ABSTRACT Introduction: Thoracic aortic aneurysm is a potentially fatal disease with a strong genetic contribution. The dysfunction of vascular smooth muscle cells (VSMCs) contributes to the formation of this aneurysm. Although previous studies suggested that long non-coding ribonucleic acid (RNA) hypoxia inducible factor 1 α-antisense RNA 1 (HIF1A-AS1) exerted a vital role in the progression and pathogenesis of thoracic aortic aneurysm, we managed to find a new regulatory mechanism of HIF1A-AS1 in VSMCs via transcriptomics. Methods: Cell viability was detected by the cell counting kit-8 assay. Cell apoptosis was assessed by Annexin V-fluorescein isothiocyanate/propidium iodide double staining. Transwell migration assay and wound healing assay were performed to check the migration ability of HIF1A-AS1 on VSMCs. The NextSeq XTen system (Illumina) was used to collect RNA sequencing data. Lastly, reverse transcription-quantitative polymerase chain reaction confirmed the veracity and reliability of RNA-sequencing results. Results: We observed that overexpressing HIF1A-AS1 successfully promoted apoptosis, significantly altered cell cycle distribution, and greatly attenuated migration in VSMCs, further highlighting the robust promoting effects of HIF1A-AS1 to thoracic aortic aneurysm. Moreover, transcriptomics was implemented to uncover its underlying mechanism. A total of 175 differently expressed genes were identified, with some of them enriched in apoptosis, migration, and cell cycle-related pathways. Intriguingly, some differently expressed genes were noted in vascular development or coagulation function pathways. Conclusion: We suggest that HIF1A-AS1 mediated the progression of thoracic aortic aneurysm by not only regulating the function of VSMCs, but also altering vascular development or coagulation function.

RESUMO Explorar o efeito clínico da terapia musical no tratamento de pacientes de meia-idade e idosos com depressão. De junho de 2019 a junho de 2020, 100 pacientes com depressão foram selecionados como objeto deste estudo, e foram divididos em um grupo controle e um grupo de observação de acordo com a ordem de consultas, sendo 50 pacientes incluídos em cada grupo. Não houve diferença significativa entre os dois grupos em termos de gênero, idade, escolaridade e tratamento medicamentoso (dose, tipo de medicação) (P>0.05). Os pacientes do grupo controle foram tratados com medicamentos antidepressivos convencionais. Os pacientes do grupo de observação adicionaram a terapia musical à terapia convencional. O terapeuta musical precisa entender completamente a situação básica do paciente e formular um plano de tratamento musical adequado de acordo com o estado real do paciente. Comparar os escores HANA e PSP entre os dois grupos de pacientes com depressão após tratamento para avaliar o efeito terapêutico dos pacientes. Os escores Hana e PSP no grupo de observação após o tratamento foram significativamente superiores às do grupo controle (P< 0.05). Para o tratamento da depressão, além da seleção de medicamentos apropriados, o estado emocional dos pacientes é mais importante. A terapia musical Como tratamento auxiliar da Terapia tradicional no tratamento da depressão nos idosos foi efetivamente verificada, portanto devemos promover ativamente sua aplicação.

ABSTRACT To explore the clinical effect of music therapy in the treatment of middle-aged and elderly patients with depression. From June 2019 to June 2020, 100 patients with depression in a community were selected as the object of this study, and were divided into a control group and an observation group according to the order of visits, with 50 patients in each group. There was no significant difference between the two groups in terms of gender, age, education level and drug treatment (medication dose, type) (P>0.05). The patients in the control group were treated with conventional antidepressant drugs. The patients in the observation group added music therapy to the conventional therapy. The music therapist needs to fully understand the basic situation of the patient and formulate a suitable music treatment plan according to the actual state of the patient. Compare the HANA and PSP scores between the two groups of depressive patients after treatment to judge the treatment effect on the patients. The Hana and PSP scores in the observation group after treatment were significantly higher than those in the control group (P<0.05). To treat depression, in addition to selecting appropriate drugs, alleviating the emotional state of patients is more important. Music therapy as an auxiliary treatment of traditional therapy, in the treatment of depression in the elderly, has been effectively verified, we should actively promote its application.

Las puntuaciones de Hana y PSP en el grupo de observación después del tratamiento fueron significativamente más altas que las del grupo de control (P <0,05). Para tratar la depresión, además de seleccionar los fármacos adecuados, es más importante aliviar el estado emocional de los pacientes. La musicoterapia como tratamiento auxiliar de la terapia tradicional, en el tratamiento de la depresión en el anciano, ha sido efectivamente comprobada, debemos promover activamente su aplicación.

RESUMO OBJETIVO Relatar os procedimentos cirúrgicos e a eficácia do uso de retalhos plantares mediais venosos para reparo de defeitos de tecidos moles dos dedos. METODOLOGIA De março de 2010 a abril de 2012, foram colhidos retalhos plantares mediais venosos para reparar ferimentos de 31 dedos em 29 casos. Entre eles, 13 dedos médios com defeitos nas pontas em 11 casos, 7 dedos com defeitos na parte dorsal em 7 casos e 11 dedos com defeitos na polpa digital em 11 casos. O tamanho dos defeitos variava de 1,2 cm × 1,5 cm a 2,5 cm × 3,5 cm. Foram colhidos retalhos plantares mediais venosos de 1,5 cm × 2 cm a 3 cm × 4 cm. Foram adotados enxertos de pele de espessura total na área doadora. RESULTADOS Todos os 31 retalhos sobreviveram, com exceção de 1 retalho com crise arterial e 2 casos com crise venosa. Esses problemas foram corrigidos a tempo com anastomoses secundárias das artérias e veias e os retalhos sobreviveram. Os ferimentos e áreas doadoras atingiram cicatrização por primeira intenção. Todos os enxertos de pele sobreviveram. Foi realizado acompanhamento pós-operatório em de 26 dedos em 24 casos por 4 a 12 meses, sendo que dos casos tratados 5 não tiveram acompanhamento. As partes dorsais dos dedos lesionados apresentaram morfologia normal, com cor e textura da pele muito similares a da pele normal. Após o reparo dos defeitos nas pontas e polpas digitais, impressões digitais apareceram e a sensação protetora foi restaurada. CONCLUSÃO Os defeitos de tecido mole dos dedos podem ser reparados de forma satisfatória com retalhos plantares mediais venosos, com poucos danos à área doadora. Este método mostrou se eficaz para o reparo de defeitos de tecido mole dos dedos.

SUMMARY OBJECTIVE To report the surgical procedures and efficacy of using medial plantar venous flap for the repair of soft tissue defects of the fingers. Methods From March 2010 to April 2012, medial plantar venous flaps were harvested to repair the wounds of 31 fingers in 29 cases. Among them, there were 13 middle fingers with defects at the tips in 11 cases, 7 fingers with defects in the dorsal part in 7 cases, and 11 fingers with defects in the finger pulp in 11 cases. The size of the defects ranged from 1.2cm×1.5 cm to 2.5cm × 3.5cm. Medial plantar venous flaps of 1.5cm × 2cm – 3×4 cm were harvested. Full-thickness skin grafts were adopted for the donor areas. RESULTS All 31 flaps survived, except for 1 flap with arterial crisis and 2 cases with venous crisis. These conditions were timely corrected by secondary anastomosis of artery and vein and the flaps survived. The wounds and the donor areas achieved healing by the first intention. All grafted skins survived. Postoperative follow-up was conducted for 26 fingers in 24 cases for 4-12 months, excluding 5 cases with lost follow-up. The dorsal part of the damaged fingers had normal morphology, and the skin color and texture were similar to those of the normal skin. After the repair of defects in the fingertip and pulp, fingerprints appeared, and the protective sensation was restored. CONCLUSION The soft tissue defects of the fingers can be satisfactorily repaired with medial plantar venous flap, and little damage is caused to the donor area. This method is proven effective for the repair of soft tissue defects of the fingers.

ABSTRACT Objectives: Rectocele with constipation might be related to methane (CH4) producing intestinal bacteria. We investigated the breath CH4 levels and the clinical characteristics of colorectal motility in constipated patients with rectocele. Methods: A database of consecutive female outpatients was reviewed for the evaluation of constipation according to the Rome III criteria. The patients underwent the lactulose CH4 breath test (LMBT), colon marker study, anorectal manometry, defecography and bowel symptom questionnaire. The profiles of the lactulose breath test (LBT) in 33 patients with rectocele (with size ≥ 2 cm) and 26 patients with functional constipation (FC) were compared with the breath test results of 30 healthy control subjects. Results: The mean size of rectocele was 3.52 ± 1.06 cm. The rate of a positive LMBT (LMBT+) was significantly higher in patients with rectocele (33.3%) than in those with FC (23.1%) or healthy controls (6.7%) (p = 0.04). Breath CH4 concentration was positively correlated with rectosigmoid colon transit time in rectocele patients (γ = 0.481, p < 0.01). A maximum high pressure zone pressure > 155 mmHg was a significant independent factor of LMBT+ in rectocele patients (OR = 8.93, 95% CI = 1.14-71.4, p = 0.04). Conclusions: LMBT+ might be expected in constipated patients with rectocele. Moreover, increased rectosigmoid colonic transit or high anorectal pressure might be associated with CH4 breath levels. Breath CH4 could be an important therapeutic target for managing constipated patients with rectocele.

Objetivo Avaliar a prevalência de diabetes melito (DM) e pré-diabetes melito (PDM) na população muçulmana no noroeste da China e discutir os fatores de risco. Materiais e métodos Selecionamos três vilarejos de acordo com a renda e a população, usando uma amostra estratificada e por cluster. Os sujeitos eram residentes com ≥ 20 anos de idade e de famílias que estavam no local há mais de três gerações. Foram feitos e analisados um questionário e o teste de tolerância oral à glicose (TTOG) para 660 sujeitos. Resultados A prevalência do DM e PDM entre as populações Han e muçulmana foi diferente (P = 0,041), e as prevalências também foram diferentes com relação à idade na população Han (P < 0,001) e muçulmana (P < 0,001), respectivamente. Exceto pela faixa etária de 20 anos de idade, a prevalência do DM e PDM na população muçulmana foi maior do que na população Han (P = 0,013), não havendo diferenças significativas para as outras faixas etárias (P > 0,05). A ingestão de sal (P < 0,001) e óleos comestíveis (P < 0,001) na população muçulmana foi mais alta do que na população Han, enquanto o tabagismo (P < 0,001) e consumo de álcool (P < 0,001) foram mais baixos. O IMC (P < 0,001), a idade (P = 0,025) e o tabagismo (P = 0,011) foram fatores de risco para o DM e PDM, mas o consumo de álcool (P < 0,001) foi um fator protetor. Conclusões No noroeste da China, a prevalência de DM é maior na população muçulmana e é especialmente mais alta na faixa etária de 20 anos de idade, quando comparada com a população Han. Isso pode ser explicado por diferenças genéticas potenciais e hábitos alimentares ruins.

Objective To survey the prevalence of diabetes mellitus (DM) and pre-diabetes mellitus (PDM) in the Muslim population in northwest China, and discuss the risk factor. Materials and methods According to the income and the population, we randomly selected 3 villages with stratified and cluster sampling. The subjects were residents ≥ 20 years of age, and were from families which have been local for > 3 generations. The questionnaire and oral glucose tolerance test (OGTT) were completed and analyzed for 660 subjects. Results The prevalence of DM and PDM between the Han and Muslim populations were different (P = 0.041). And the prevalence were also different with respect to age in the Han (P < 0.001) and Muslim population (P < 0.001) respectively. Except for the 20-year-old age group the prevalence of DM and PDM within the Muslim population was higher than the Han (P = 0.013), we did not find any significant difference for other age groups (P > 0.05). The intake of salt (P < 0.001) and edible oil (P < 0.001) in the Muslim population was higher than the Han, while cigarette smoking (P < 0.001) and alcohol consumption (P < 0.001) was lower. BMI (P < 0.001), age (P = 0.025), and smoking cigarettes (P = 0.011) were risk factors for DM and PDM, but alcohol consumption (P < 0.001) was a protective factor. Conclusions In northwest China, the prevalence of DM was higher in the Muslim population, and it was special higher on the 20-year-old age compared to the Han. This might be explained by the potential genetic differences and poor dietary habits.

BACKGROUND: Testis-expressed sequence 101 (TEX101) was found to be highly expressed in testis and involved in acrosome reaction in previous studies. Recently, the metastasis suppressor function of TEX101 in cancer was disclosed, but the comprehensive investigation of its expression has rarely been reported. In this study, the expression features of TEX101 in normal human organs and seminoma were systematically analyzed. RESULTS: Immunohistochemistry demonstrated intense staining of TEX101 in human testis tissues; however, its expression in 27 other types of normal human organs, including the ovary, was negligible. Higher expression of TEX101 was observed in the spermatocytes and spermatids of the testis, but relatively lower staining was detected in spermatogonia. Western blotting showed a single TEX101 band of 38 kDa in human testis, but it did not correspond to the predicted molecular weight of its mature form at 21 KDa. Furthermore, we examined seminoma tissues by immunohistochemistry and found that none of the 36 samples expressed TEX101. CONCLUSIONS: Our data confirmed TEX101 to be a testis protein that could be related to the maturation process of male germ cells. The lack of TEX101 in seminoma indicated its potential role in tumor progression. This characteristic expression of TEX101 could provide a valuable reference for understanding its biological functions.

In this report, we describe combined polymorphisms of the UGT1A9, UGT1A7 and UGT1A1 genes in 100 unrelated, healthy Chinese Han subjects. The functional regions of these genes were sequenced and comprehensively analyzed for genetic polymorphisms. Thirty variants were detected, including five novel forms. Tentative functional predictions indicated that a Cys → Arg substitution at position 277 in the UGT1A7 gene could alter the protein conformation and that 12460T > G in the 3'UTR might influence protein translation through specifically expressed miRNAs. UGT1A9*1b was a major functional variant in the subjects examined whereas the *1f allele had a frequency of only 0.5%. A special functional haplotype (GAGAAC) was identified for UGT1A9, 1A7 and 1A1. These findings provide fundamental genetic information that may serve as a basis for larger studies designed to assess the metabolic phenotypes associated with UGT1A polymorphisms. They also provide important data for the implementation of personalized medicine in Chinese Han.

OBJECTIVE: To determine the burden of enteric fever through trends in morbidity and mortality, bacterial species and antimicrobial resistance in Guangxi, a southern, subtropical, coastal province of China with a disproportionally large burden of enteric fever. METHODS: Data on morbidity and mortality caused by enteric fever between 1994 and 2004 were extracted from the Guangxi Center for Disease Control and Prevention. Laboratory-based surveillance and outbreak investigations were integrated with reports of notifiable infectious diseases to estimate the bacterial species-specific incidence of enteric fever. To adjust for underreporting, survey data were collected from three prefectures that represent the hyper-, moderate- and low-endemic regions of Guangxi province. FINDINGS: In Guangxi province, enteric fever incidence rate varied over the study period, with a peak of 13.5 cases per 100000 population in 1995 and a low of 6.5 in 2003. The disease occurred most frequently during the summer and autumn months and in the group aged 10-49 years. The incidence of enteric fever varied by region within Guangxi province. During the 11-year period covered by the study, 61 outbreaks of enteric fever were reported, and Salmonella paratyphi A (SPA) became the predominant causative agent in the province. CONCLUSION: Prospective studies may provide a better understanding of the reason for the shifting epidemiology of enteric fever in Guangxi province. Given the emergence of resistance to first- and second-line antimicrobials for the treatment of enteric fever, a bivalent vaccine against both SPA and S. typhi would facilitate for disease control.

OBJETIVOS: Determinar la carga de fiebre tifoidea mediante las tendencias de morbilidad y mortalidad, las especies bacterianas y la resistencia a los antibióticos en Guangxi, una provincia costera y subtropical del Sur de China, con una carga de fiebre tifoidea desproporcionalmente elevada. MÉTODOS: Los datos sobre morbilidad y mortalidad causadas por la fiebre tifoidea entre 1994 y 2004 se recogieron en el Centro de control y prevención de enfermedades de Guangxi. Con el fin de estimar la incidencia específica de la fiebre tifoidea para cada una de las especies bacterianas se incorporaron informes de enfermedades infecciosas de declaración obligatoria a la vigilancia basada en pruebas analíticas y las investigaciones de los brotes epidémicos. Para el ajuste de los subregistros se recopilaron los datos del estudio procedentes de tres prefecturas representantes de las regiones hiperendémicas, mesoendémicas e hipoendémicas de la provincia de Guangxi. RESULTADOS: La tasa de incidencia de la fiebre tifoidea en la provincia de Guangxi varió a lo largo del estudio, registrando un pico máximo de 13,5 casos por cada 100 000 habitantes en 1995 y un mínimo de 6,5 en 2003. La enfermedad tuvo una mayor incidencia durante los meses de verano y otoño, así como en el grupo de edad comprendido entre 10 y 49 años. La incidencia de la fiebre tifoidea varió según las regiones dentro de la misma provincia de Guangxi. Durante los 11 años que duró el estudio se declararon 61 brotes epidémicos de fiebre tifoidea, siendo la Salmonella paratyphi A (SPA) el agente causal predominante en la provincia. CONCLUSIÓN: Los estudios prospectivos pueden ayudar a comprender mejor la causa de los datos epidemiológicos cambiantes de la fiebre tifoidea en la provincia de Guangxi. Una vacuna bivalente contra SPA y S. typhi facilitaría el control de la enfermedad, teniendo en cuenta la aparición de resistencias a los antibióticos de primera y segunda línea para el tratamiento de la fiebre tifoidea.

OBJECTIF: Déterminer le fardeau que représente la fièvre typhoïde au travers des tendances de morbidité et de mortalité, des espèces bactériennes et de la résistance antimicrobienne dans le Guangxi, une province subtropicale côtière du sud de la Chine présentant un fardeau anormalement important de fièvre typhoïde. MÉTHODES: Les données de morbidité et de mortalité causées par la fièvre typhoïde entre 1994 et 2004 ont été obtenues auprès du Centre de contrôle et de prévention des maladies du Guangxi. La surveillance en laboratoire et les enquêtes sur les résurgences ont été intégrées aux rapports des maladies infectieuses à déclaration obligatoire pour permettre d'estimer l'incidence spécifique d'espèces bactériennes de la fièvre typhoïde. Afin de compenser les sous-déclarations, les données du sondage ont été recueillies auprès de trois préfectures caractéristiques des régions hyper, modérément et faiblement endémiques de la province du Guangxi. RÉSULTATS: Dans la province du Guangxi, le taux d'incidence de la fièvre typhoïde a varié au cours de la période d'étude, avec un pic de 13,5 cas par 100 000 habitants en 1995 et un minimum de 6,5 en 2003. La maladie est fréquemment survenue pendant les mois d'été et d'automne, et dans la tranche d'âge 10-49 ans. L'incidence de la fièvre typhoïde a varié de région en région dans la province du Guangxi. Pendant la période de 11 ans couverte par l'étude, 61 résurgences de fièvre typhoïde ont été rapportées, et l'agent causatif prédominant dans la province était Salmonella paratyphi A (SPA). CONCLUSION: De futures études devraient fournir une meilleure compréhension de la raison de la variabilité épidémiologique de la fièvre typhoïde dans la province du Guangxi. Étant donné l'apparition de résistance aux première et deuxième lignes de traitements antimicrobiens de la fièvre typhoïde, un vaccin bivalent contre SPA et S. typhi faciliterait le contrôle de la maladie.
