Non-small-cell lung cancer (NSCLC) patients who experience brain metastases are usually associated with poor prognostic outcomes. This retrospective study proposed to assess whether bevacizumab or gefitinib can be used to improve the effectiveness of whole brain radiotherapy (WBRT) in managing patients with brain metastases. A total of 218 NSCLC patients with multiple brain metastases were retrospectively included in this study and were randomly allocated to bevacizumab-gefitinib-WBRT group (n=76), gefitinib-WBRT group (n=77) and WBRT group (n=75). Then, tumor responses were evaluated every 2 months based on Response Evaluation Criteria in Solid Tumors version 1.0. Karnofsky performance status and neurologic examination were documented every 6 months after the treatment. Compared to the standard WBRT, bevacizumab and gefitinib could significantly enhance response rate (RR) and disease control rate (DCR) of WBRT (P<0.001). At the same time, RR and DCR of patients who received bevacizumab-gefitinib-WBRT were higher than those who received gefitinib-WBRT. The overall survival (OS) rates and progression-free survival (PFS) rates also differed significantly among the bevacizumab-gefitinib-WBRT (48.6 and 29.8%), gefitinib-WBRT (36.7 and 29.6%) and WBRT (9.8 and 14.6%) groups (P<0.05). Although bevacizumab-gefitinib-WBRT was slightly more toxic than gefitinib-WBRT, the toxicity was tolerable. As suggested by prolonged PFS and OS status, bevacizumab substantially improved the overall efficacy of WBRT in the management of patients with NSCLC.

ABSTRACT A 35 d trial was conducted to evaluate the effects of dietary supplementation of co-fermented agricultural by-products, soybean hulls and Pleurotus eryngii stalk residue (PESR), with Aureobasidium pullulans on nutrients digestibility and meat quality in broilers fed on conventional corn-soybean meal basal diet. A total of 400 1-d-old Ross broilers were allotted to 4 dietary treatments with 4 replicate pens (25 birds per pen). Birds were fed the corn-soybean meal diets supplemented with 0% (CON), 0.5% fermented soybean hulls (0.5% FSBH), 0.5% fermented soybean hulls partially replaced with PESR (0.5% FSHP) and 1.0% FSHP. The broilers fed on the diet that contained fermented products had higher total tract apparent digestibility for hemicellulose than those on CON (p<0.05). Meanwhile, the birds fed on 0.5% FSHP also showed the lightest duodenum and jejunum weight among all groups. Compared with the CON, the inclusion of 1.0% FSHP in the diet significantly decreased ammonia N concentration in cecum followed by 0.5% FSHP and subsequent 0.5% FSBH group. Dietary supplementation of fermented products significantly improved WHC and increased protein content in meat as compared with the CON. Moreover, the fat content in meat decreased in the broilers that received 0.5% FSBH and 1.0% FSHP. In conclusion, dietary supplementation of co-fermented agricultural by-products, PESR and soybean meal, could improve the digestibility of hemicellulose and decrease the cecal ammonia N concentration; moreover, the increased WHC and protein level as well as decreased fat content in meat suggested the promising utilization of these low-cost materials as broiler feed additives.

microRNA (miR)-142-3p is implicated in malignancy and has been identified as a biomarker for aggressive and recurrent lung adenocarcinomas. This study aimed to evaluate the inhibitory effect of miR-142-3p on apoptosis and inflammation induced by bleomycin in MLE-12 cells. MLE-12 cells were first transfected either with miR-142-3p mimic or miR-142-3p inhibitor and then the cells were exposed to 50 μg/mL of bleomycin. Thereafter, cell viability, apoptosis and the expression of pro-inflammatory cytokines were assessed using CCK-8, flow cytometry, RT-PCR and western blot analyses. Cox-2, PI3K, AKT and mTOR expressions were detected by western blotting after bleomycin was administered together with NS-398 (an inhibitor of Cox-2). As a result, cell viability was significantly decreased, as well as apoptosis and the expression of IL-1 and TNF-α were remarkably increased after 50 and 100 μg/mL of bleomycin administration. miR-142-3p overexpression alleviated bleomycin-induced apoptosis and overproduction of these two pro-inflammatory cytokines, while miR-142-3p suppression exhibited completely opposite results. Up-regulation of Cox-2 and inactivation of PI3K/AKT/mTOR were found in bleomycin-pretreated cells, while these abnormal regulations were partially abolished by miR-142-3p overexpression and NS-398. In conclusion, this study demonstrated that miR-142-3p overexpression protected bleomycin-induced injury in lung epithelial MLE-12 cells, possibly via regulating Cox-2 expression and PI3K/AKT/mTOR signaling pathway. These findings provide evidence that miR-142-3p may be a therapeutic strategy for idiopathic pulmonary fibrosis (IPF) treatment.

Male circumcision is the most frequently performed procedure by urologists. Safety and efficacy of the circumcision procedure requires continual improvement. In the present study, we investigated the safety and efficacy of a new male circumcision technique involving the use of a circular stapler. In total, 879 consecutive adult male patients were randomly divided into 2 groups: 441 underwent stapler circumcision, and 438 underwent conventional circumcision. The operative time, pain score, blood loss volume, healing time, treatment costs, and postoperative complications were compared between the two groups. The operative time and blood loss volume were significantly lower in the stapler group than in the conventional group (6.8 ± 3.1 vs 24.2 ± 3.2 min and 1.8 ± 1.8 vs 9.4 ± 1.5 mL, respectively; P<0.01 for both). The intraoperative and postoperative pain scores were significantly lower in the stapler group than in the conventional group (0.8 ± 0.5 vs 2.4 ± 0.8 and 4.0 ±0.9 vs 5.8 ± 1.0, respectively; P<0.01 for both). Additionally, the stapler group had significantly fewer complications than the conventional group (2.7% vs 7.8%, respectively; P<0.01). However, the treatment costs in the stapler group were much higher than those in the conventional group (US$356.60 ± 8.20 vs US$126.50 ± 7.00, respectively; P<0.01). Most patients (388/441, 88.0%) who underwent stapler circumcision required removal of residual staple nails. Overall, the present study has shown that stapler circumcision is a time-efficient and safe male circumcision technique, although it requires further improvement.

A previous study showed that BMP-2 (bone morphogenetic protein-2) and wear debris can separately support osteoclast formation induced by the receptor activator of NF-κB ligand (RANKL). However, the effect of BMP-2 on wear debris-induced osteoclast formation is unclear. In this study, we show that neither titanium particles nor BMP-2 can induce osteoclast formation in RAW 264.7 mouse leukemic monocyte macrophage cells but that BMP-2 synergizes with titanium particles to enhance osteoclast formation in the presence of RANKL, and that at a low concentration, BMP-2 has an optimal effect to stimulate the size and number of multinuclear osteoclasts, expression of osteoclast genes, and resorption area. Our data also clarify that the effects caused by the increase in BMP-2 on phosphorylated SMAD levels such as c-Fos expression increased throughout the early stages of osteoclastogenesis. BMP-2 and titanium particles stimulate the expression of p-JNK, p-P38, p-IkB, and P50 compared with the titanium group. These data suggested that BMP-2 may be a crucial factor in titanium particle-mediated osteoclast formation.

OBJECTIVE: We attempted to evaluate maternal thyroid function in a new self-sequential longitudinal reference interval (SLRI) which we established recently. By this method, we analysed the correlation between pregnancy outcome, neonatal thyroid stimulating hormone (TSH) level and maternal thyroid diseases. METHODS: A total of 1744 pregnant women participated in the study and 1747 babies were born from those women (three bore twins). The levels of TSH, free thyroxine (FT4) and thyroid peroxidase antibodies (TPO-Ab) of mothers were quantified by electrochemistry immunoassay (ECL). The levels of neonatal blood TSH were detected by time-resolved fluorescence immunoassay (TRFIA). All data were collected and statistically analysed by SPSS 13.0 software. RESULTS: With our new SLRI method, we found that 0.11%~3.84% pregnant women would get thyroid diseases. Subclinical hypothyroidism was the most common maternal thyroid disorder. Being positive for thyroid peroxidase antibodies was a significant risk factor of subclinical hypothyroidism during pregnancy. The median, P2.5~P97.5, and interquartile range (IQR) of neonatal TSH (N-TSH) of 1747 babies were 2.72 mIU/L, 0.10~8.01 mIU/L and 2.62 mIU/L, respectively; 28.6% of pregnant women with thyroid diseases developed pregnancy complications. The prevalence was significantly higher than in the normal thyroid function group (p< 0.001). The levels of N-TSH were low correlated with maternal TSH levels (p < 0.05), but there were no significant correlations between N-TSH and maternal FT4 and maternal TPO-Ab (p > 0.05). CONCLUSIONS: Thyroid disorders, especially subclinical hypothyroidism, are common in pregnant women. These disorders are associated with pregnancy and fetal outcome. Routine maternal thyroid function screening is important and should be recommended.

OBJETIVO: Intentamos evaluar la función tiroidea materna en un nuevo intervalo de referencia longitudinal auto-secuencial (SLRI) que establecimos recientemente. Por este método, analizamos la correlación entre el resultado del embarazo, el nivel de la hormona estimulante de la tiroides (TSH) en neonatos, y las enfermedades tiroideas maternas MÉTODOS: Un total de 1744 mujeres embarazadas participó en el estudio y 1747 bebés nacieron de esas mujeres (tres de ellas tuvieron gemelos). Los niveles de TSH, la tiroxina libre (FT4), y los anticuerpos de la peroxidasa tiroidea (TPO-Ab) de las madres, fueron cuantificados mediante inmunoensayo electroquímico (ECL). Los niveles de TSH en la sangre de los neonatos, fueron determinados mediante inmunoensayo por fluorescencia resuelto en el tiempo (TRFIA). Todos los datos fueron recogidos y analizados estadísticamente usando el software SPSS 13.0 RESULTADOS: Con nuestro nuevo método SLRI, encontramos que 0.11%~3.84% de las mujeres embarazadas contraerán enfermedades tiroideas. El hipotiroidismo subclínico fue el trastorno de la tiroides materna más común. Ser positivo a los anticuerpos de la peroxidasa tiroidea fue un factor de riesgo significativo del hipotiroidismo subclínico durante el embarazo. La mediana, P2.5~P97.5, y el rango intercuartil (IQR) de la TSH (N-TSH) neonatal de los 1747 bebés fueron 2.72 mIU/L, 0.10~8.01 mIU/L y 2.62 mIU/L respectivamente. El 28.6% de las mujeres embarazadas que tenían enfermedades tiroideas, desarrollaron complicaciones del embarazo. La prevalencia fue significativamente más alta que en el grupo con función tiroidea normal (p < 0.001). Los niveles de N-TSH fueron bajos en correlación con los niveles de TSH maternos (p < 0.05), pero no hubo ninguna correlación significativa entre la N-TSH y la FT4 materna, y la TPO-Ab materna (p > 0.05). CONCLUSIÓNS: Los trastornos tiroideos, especialmente el hipotiroidismo, son comunes en las mujeres embarazadas.Estos trastornos se hallan asociados con el resultado del embarazo y el resultado fetal. El tamizaje de rutina de la función tiroidea materna es importante y debe recomendarse.

OBJECTIVE: To survey Human Papilloma Virus (HPV) infection in Chinese Women of Jiangsu Province and discuss the relationship between HPV and the biology of cervical cancer. METHODS: Two thousand, one hundred and fifty-three sexually active women (including 66 cases of cervical cancer) were selected for high-risk human papilloma virus DNA test with Hybrid Capture II (HCII). RESULTS: The overall HPV prevalence was 32.6% (701/2153) with higher positive rates in cervical carcinoma and Cervical Interstitial Neoplasia (CIN) [93.9% and 54.6%] respectively. For women aged 40-59 years, the overall high-risk HPV prevalence was higher than those of other age groups. Compared with CIN I, the positivity rate and viral load of HPV DNA in CIN III is much higher (80.2% vs 29.9%, 11.89 vs 0.53). Ninety-four per cent (64/66) of patients with Cervical cancer were detected to be HPV positive. There was no significant difference in HPV DNA among each clinical stage and pathologic grade. But the positive rates and the value of HPV DNA were higher in the patients with cervical interstitial incursion. Eighty per cent of patients (20/25) could become negative within six months after operation. CONCLUSIONS: High-risk HPV DNA test is effective in screening for cervical diseases. HC II is an effective method to detect HPV DNA.

OBJETIVO: Investigar la infección por el virus del papiloma humano (VPH) en las mujeres chinas de la Provincia de Jiangsu y analizar la relación entre VPH y la biología del cáncer cervical o del cuello uterino. MÉTODOS: Dos mil ciento cincuenta y tres mujeres sexualmente activas (incluyendo 66 casos de cáncer cervical) fueron seleccionadas para una prueba de ADN con el fin de detectar el virus del papiloma humano de alto riesgo mediante Captura Híbrida 2 (HC2). RESULTADOS: La prevalencia general de VPH fue 32.6% (701/2153), hallándose las tasas positivas más altas en el carcinoma cervical y la neoplasia intersticial cervical (NIC) [93.9% y 54.6%]. Para las mujeres de 40-59 años de edad, la prevalencia general de VPH de alto riesgo fue mayor que para los otros grupos etarios. En comparación con el CIN, la tasa de positividad y la carga viral de ADN del VPH en el CIN es mucho mayor (80.2% vs 29.9%, 11.89 vs 0.53). Se detectó que noventa y cuatro por ciento (64/66) de las pacientes con cáncer del cuello uterino eran VPH positivas. No hubo ninguna diferencia significativa en el ADN del VPH ADN entre cada fase clínica y el grado patológico. No obstante, tanto las tasas positivas como el valor de VPH ADN fueron más altos en las pacientes con incursión intersticial cervical. Ochenta por ciento de las pacientes (20/25) podrían volverse negativas en seis meses tras la operación. CONCLUSIONES: La prueba de ADN para la detección del virus del papiloma humano de alto riesgo es un medio efectivo para el tamizaje de las enfermedades cervicales. El HC2 es un método efectivo para detectar el ADN del VPH.
