Objective To investigate the effects of self-made Yishen Antai Decoction combined with progesterone in the treatment of recurrent spontaneous abortion (RSA) and the effect on pregnancy outcomes and blocking antibodies (BA). Methods 100 cases of patients with RSA were randomly divided into the observation group and the control group, 50 cases in each group. The control group was treated with progesterone and on the basis, the observation group was additionally treated with self-made Yishen Antai Decoction. Both groups were intervened till 12 weeks of gestation, and the clinical curative effect was evaluated. Results The total effective rate of treatment, the success rate of pregnancy and the positive rate of blocking antibody (BA) showed significant differences between the observation group and the control group (P< 0.05). After treatment, the total TCM symptom score and serum levels of interleukin-2 (IL-2) and interferon-γ (IFN-γ) were significantly lower while interleukin-10 (IL-10) level was significantly higher in the observation group than the control group (P< 0.05). There were no serious adverse reactions in the two groups. Conclusion Self-made Yishen Antai Decoction is effective and safe in the treatment of RSA. It can significantly improve the success rate of pregnancy and the positive rate of BA, which may be associated with the regulation of IL-2, IL-10 and IFN-γ levels.

Objective Anovel index based on frequency-domain analysis of heart rate variability (HRV) was tested on patients with reduced left ventricular systolic function.This index,namely VHFI,was defined as the very high frequency (VHF) component of the power spectrum normalized to represent its relative value in proportion to the total power minus the very low frequency component.Methods Patients (n=130) were divided into a study group,consisting 66 patients with decreased left ventricular systolic function,and a control group,consisting 64 patients with normal heart structure and function and without severe coronary artery stenosis (＜50%).Results VHFI in the study group was significantly higher than that in the control group (19.17±13.35 vs 11.37±10.77,P＜0.001).Cardiac events occurred in 18 patients during follow-up (33.34±3.26 months).Defining the positive test as VHFI =15 and negative test as VHFI ＜15,achieved a sensitivity of 57.58% and a specificity of 78.13% for predicting decreased left ventricular systolic function,and achieved a sensitivity of 66.67% and a specificity of 64.29% for predicting cardiac events.Univariate Cox regression analysis showed that positive VHFI test was an independent variable in predictive cardiac events.Conclusions The results suggest that VHFI is a useful tool for quick evaluation of left ventricular systolic function and prediction of prognosis.

Objective To make an evidence-based rehabilitation plan for a patient with osteogenesis imperfecta after external fixation. Methods Based on a comprehensive assessment for the patient's condition, the clinical problems were listed. Related articles were searched from National Guideline Clearinghouse (NGC), The Cochrane Library, PubMed, CBM, CNKI and Wanfang databases. And the reference list of each eligible article was also included. Finally the optimum rehabilitation program was designed with optimal clinical evidence, patient's conditions and relatives' willingness. Results 1 randomized controlled trial and 4 case reports were included. A progressive exercise program was developed and implemented. No new fractures occurred during the intervention. Muscle strength, gait, activities of daily living had been greatly improved. 20 weeks later, the Berg score was 43 and the Barthel index was 80. Conclusion The progressive rehabilitation exercise program developed from evidence-based practice is safe, effective and feasible.

Compared with hip replacement, internal fixation in the treatment of the elderly femoral neck fracture, especially the application of cannulated screws, is minimally invasive, easy to operate and economical. In recent years, it becomes the research focus in the field of orthopedic clinical research. However, configuration of cannulated screws is still controversial. Most clinicians believe that three cannulated screws being placed in parallel in an inverted triangle configuration is better than that in a triangular configuration in biomechanics and clinical effect. Nonparallel strong oblique nailing technique allows the screws to share more weight to reduce postoperative complications, so that it is more suitable for elderly patients with osteoporosis. However, the related complications of internal fixation such as nonunion, femoral neck shortening and other problems are still the focus of domestic and foreign scholars. Issues about how to control the indication of internal fixation surgery, understand related factors of the complications, and prevent complications are required to be further explored.

Medical examination is an important measurement of evaluating the teaching effect and studying results,and also is the main method and content of teaching quality evaluation in universities and colleges.During the teaching evaluation we found that many problems of medical examination need to be solved and improved.This paper deals with three major aspects closely related to teachers including the standardization of programming test paper,rating the test scores,and statistical analysis of the examination papers.

The professional skill schools started an activity,which is the important measure to popularize the strategy of“the science and education making our country prosper”,that is,the definition of professional skill and implement of institution of professional certificates.It is the development direction of professional education that implementing of the institution of double-certificates',creating the new mode of cultivating the individuals,and strengthening the tuition of students'skill to make the students to acquire the education diplomas and the pro- fessional certificates.This issue points out the way and some opinions in this work,in the terns that imploring practice of the identification of the professional skill of microorganism inspecting worker' and the joint of microorganism education reform.

The co-metabolic carbon sources,dynamics and influence factors of atrazine biotransformation by genetically engineered microor- ganism(GEM)were investigated in the paper.The results showed that glucose was superior to acetate as co-metabolic carbon sources.The concentration of carbon sources affected little on atrazine transformation but much on GEM growth.The specific transformation rate(STR)of atrazine was influenced not by cell density of GEM but by atrazine concentration.Monod model was used to simulate atrazine transformation dynamics and the parameters were v_(max)=0.168/h and Ks=30.49 mg/L.When temperature reduced,STR decreased markedly.The trans- formation was efficient in weak alkaline condition and was inhibited in acidic condition.To some extent,salinity did not affect transformation activity of GEM.Co~(2+),Fe~(2+),Fe~(3+),and Zn~(2+) improved atrazine transformation,but Mn~(2+),Ni~(2+) and Cu~(2+) inhibited atrazine transforma- tion.The results also showed that there existed a direct correlation between adsorption and transformation of atrazine by GEM.

Pharmacogenomics is defined as the study of the association between genetics and drug response. This review includes basic concepts of pharmacogenomics, heterogeneity of hypertension and antihypertensive drug responses, genes associate with drug metabolism, and individualized drug therapy. The knowledge of genes that influence the pharmacodynamic determinants of blood pressure response to antihypertensive medications has the potential to provide new insights not only into molecular mechanisms influencing drug response, but also into the role that these genes may play in determining interindividual differences in blood pressure level and the occurrence of hypertension.

Objective To investigate vascular endothelial growth factor(VEGF) and TNF-α levels in the serum of patients with primary hepatocellur carcinoma(HCC),and to evaluate their relevance with the development and metastasis of HCC.Methods VEGF and TNF-α levels in serum were examined by enzyme linked immunosorbent assay(ELISA) technology in 87 patients with HCC and 10 healthy individuals.Results Serum VEGF and TNF-α,levels in HCC patients were significantly higher than that in the contorl group.In addition,HCC patients infected with hepatitis virus(including HBV and HCV) showed a remarkable elevation in serum VEGF and TNF-α levels.The VEGF and TNF-α levels in HCC with metastasis were also higher than those without metastasis.Conclusion The serum VEGF and TNF-α levels in HCC patients might serve as the pivotal biological indices that could reflect HCC progressien and metastasis.
