Abstract Objectives To investigate the changes in the coagulation function and hemodynamic parameters in patients with Hemorrhagic Traumatic Shock (HTS) after restrictive fluid resuscitation. Methods A total of 139 patients with HTS admitted to our hospital were enrolled, among which 69 HTS patients were divided into the control group and the remaining 70 HTS patients as the observation group. Patients in the control group underwent regular fluid resuscitation, while those in the observation group underwent restrictive fluid resuscitation. Results During treatment, 70 patients in the observation group had a lower bleeding amount, infusion amount, and blood transfusion volume than those in the control group (p < 0.05). After treatment, patients in the observation group had better hemodynamic parameters and blood coagulation than those in the control group (p < 0.05), and the incidence rate in the observation group was only 12.9%, which was significantly lower than 60.87% in the control group, while the cure rate in the observation group was 100%, which was significantly higher than that in the control group (p < 0.05). Conclusions Restrictive fluid resuscitation could remarkably increase the cure rate and reduce the bleeding amount during HTS treatment, thereby benefiting the recovery of the patient's blood coagulation.

Abstract Coronary heart disease (CHD) is one of the main diseases causing morbidity and mortality globally, with oxidative damage and lipid peroxidation associated with oxidative stress and atherosclerosis. Cinnamomum migao is a Miao ethnomedicine that has been shown to provide relief from CHD symptoms. A gas chromatograph-mass spectrometer (GC-MS) was used to determine the chemical components of ten batches of migao fatty oil (MFO), yielding a total of 35 chemical constituents. The antioxidant activity of MFO in vitro was assessed using the DPPH· and ABTS·+ assay methods, and both indicated good antioxidant activity. The network pharmacology predicted the active constituents of MFO and their therapeutic influence on the mechanism of oxidative damage-induced coronary heart disease (OD-CHD). Six compounds were discovered in MFO, including tau-cadinol acetate and dodecanoic acid, which may play a role in OD-CHD by acting on lipids and atherosclerosis, the PI3K-Akt signalling pathway, and other pathways. In conclusion, our study lays the foundation for investigating the use of MFO in the treatment of OD-CHD.

OBJECTIVES: Patients with Type I neurofibromatosis scoliosis with intra-canal rib head protrusion are extremely rare. Current knowledge regarding the diagnosis and treatment for this situation are insufficient. The purpose of this study is to share our experience in the diagnosis and surgical treatments for such unique deformities. METHODS: Six patients with Type I neurofibromatosis scoliosis with rib head dislocation into the spinal canal were diagnosed at our institution. Posterior instrumentation and spinal fusion without intra-canal rib head resection via a posterior-only approach was performed for deformity correction and rib head extraction. The efficacy and outcomes of the surgery were evaluated by measurements before, immediately and 24 months after the surgery using the following parameters: coronal spinal Cobb angle, apex rotation and kyphosis of the spine and the intra-canal rib head position. Post-operative complications, surgery time and blood loss were also evaluated. RESULTS: Patients were followed up for at least 24 months post-operatively. The three dimensional spinal deformity was significantly improved and the intra-canal rib head was significantly extracted from the canal immediately after the surgery. At follow-up 24 months after surgery, solid fusions were achieved along the fusion segments, and the deformity corrections and rib head positions were well maintained. There were no surgery-related complications any time after the surgery. CONCLUSIONS: Systematic examinations are needed to identify patients with Type I neurofibromatosis scoliosis with rib head dislocation into the canal who can be treated by posterior-only spinal fusion without rib head resection.

Sichuan basin, situated in the west of China, is the fourth biggest basin in China. In order to describe a systematic study of the cry2-type genes resources from Bacillus thuringiensis strains of Sichuan basin, a total of 791 Bacillus thuringiensis strains have been screened from 2650 soil samples in different ecological regions. The method of PCR-restriction fragment length polymorphism (PCR-RFLP) was used to identify the type of cry2 genes. The results showed that 322 Bacillus thuringiensis strains harbored cry2-type genes and four different RFLP patterns were found. The combination of cry2Aa/cry2Ab genes was the most frequent (90.4%), followed by cry2Aa (6.8%) and cry2Ab alone (2.5%), and only one novel type of cry2 gene was cloned from one isolate (JF19-2). The full-length of this novel gene was obtained by the method of thermal asymmetric interlaced PCR (Tail-PCR), which was designated as cry2Ag1 (GenBank No. ACH91610) by the Bt Pesticide Crystal Protein Nomenclature Committee. In addition, the result of scanning electron microscopic (SEM) observation showed that these strains had erose, spherical, bipyramidal, and square crystal. And the results of sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) demonstrated that these strains harbored about one to three major proteins. These strains exhibited a wide range of insecticidal spectrum toxic to Aedes aegypti (Diptera) and Pieris rapae Linnaeus, 1758 (Lepidoptera). Particularly, JF19-2 contained cry2Ag gene had the highest insecticidal activity. All these researches mentioned above revealed the diversity and particularity of cry2-type gene resources from Bacillus thuringiensis strains in Sichuan basin.

Electrodeposition of polypyrrole films on aluminum from aqueous solutions containing p-toluene sulfonic acid and pyrrole was performed by cyclic voltammetry and galvanostatic technique. The influence of applied current density on the morphology of the films was studied by Scanning Electron Microscopy. The films displayed a cauliflower-like structure consisting of micro-spherical grains. This structure is related to dopand intercalation in the polymeric chain. Films deposited at higher current density were more susceptible to the formation of pores and defects along the polymeric chain than films deposited at lower current density. These pores allow the penetration of aggressive species, thereby favoring the corrosion process.

beta-dicarbonyl compounds were oxidized electrocatalytically, with fragmentation and loss of "ch2", using ceric methanesulphonate as a mediator. 2,4-pentanedione yields acetic acid (90%), methyl acetoacetate yields acetic acid (84%) plus methanol and dimethyl malonate yields methanol (64%). For 1,3-diphenyl-1,3-propanedione and 1,3-cyclohexanedione, benzoic acid (61% yield) and glutaric acid (75% yield) were obtained, respectively. Methyl cyanoacetate and malononitrile were inert.

Estudou-se em Ribeirão Preto, SP, Brasil, no período de 1º de junho de 1978 a 31 de maio de 1979, 98% do universo de nascidos vivos, totalizando 8878 crianças nascidas de parto único, sendo 6750 procedentes de Ribeirão Preto. Observou-se um aumento da proporção de mães adolescentes em Ribeirão Preto (14,1%) quando comparada com estudo realizado 10 anos antes (11,7%). A idade materna menor de 20 anos esteve associada com os indicadores mais desfavoráveis para a saúde perinatal, no que diz respeito à atenção médica à gestação e ao parto. Essa situação ficou mais evidente entre as mães adolescentes de classes sociais menos favorecidas, revelando que o grupo de mães adolescentes não é homogêneo, mas apresenta diferentes proporções de risco para a saúde perinatal de acordo com as frações de classe social que existem no seu interior.

Ninety-eight percent of all live births occuring in the city of Ribeirão Preto, state of São Paulo (Brazil), from June 1, 1978 to May 30, 1979 were studied, for a total of 8,878 single-delivery infants, 6,750 of whom were from this town. An increase in the proportion of teenage mothers in Ribeirão Preto (14.1%) was observed in relation to a study carried out ten years before (11.7%). Maternal age of less than 20 years was associated with more unfavorable perinatal health indicators with respect to medical care and delivery. This situation was more evident among teenage mothers from underprivileged social classes, showing that the group of teenage mothers is not homogeneous but presents different risk rates for perinatal health according to the social strata of which the group is composed.
