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.

Vascular prosthesis can absorb y-globulin or fibrinogen when they are transplanted in vivo, accordingly the cellular components in blood, such as platelet, are easy to attach on surface and become fiat shape to be activated, which then result in an inreversible aggregation and thrombus formation. During the process of transplanting vascular prosthesis at a diameter of more than 6 mm, a high vascular patency rate can be observed, while small-diameter (< 6 mm) vascular prosthesis transplantation is under low blood flow, therefore it produces the thrombosis. It is necessary to conduct surface modification of small-diameter vascular prosthesis and to enhance hemocompatibility. The main methods of modification include the alter of surface structure of vascular prosthesis, the augmentation of endothelial cells attachment on surface of vascular prosthesis, and grafting modification of vascular prosthesis surface.

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.

Objective:To explore therapeutic effect of pharyngeal treatment machine (PTM) combined resuscitating acupuncture (RA) on patients with dysphagia after stroke.Methods: A total of 98 stroke patients with dysphagia were selected.According to random number table, they were randomly and equally divided into pure pharyngeal treatment group (received pure PTM therapy based on routine treatment) and combined treatment group (received RA based on pure pharyngeal treatment group).Video fluorography (VFG) score and swallow-quality of life (SWAL-QOL) score before and after treatment, and total effective rate were evaluated and compared between two groups.Results: Compared with before treatment, there was significant rise in VFG score, and significant reduction in SWAL-QOL score in both groups after treatment, P<0.01 all;compared with pure pharyngeal treatment group after treatment, there was significant rise in VFG score [(5.46±2.04) scores vs.(6.54±2.75) scores], and significant reduction in SWAL-QOL score [(741.33±25.92) scores vs.(632.54±26.77) scores] in combined treatment group, P=0.032, 0.001 respectively.Total effective rate of combined treatment group was significantly higher than that of pure pharyngeal treatment group (93.88% vs.75.51%), P=0.014.Conclusion: Compared with pure pharyngeal treatment machine, pharyngeal treatment machine combined resuscitating acupuncture possesses better therapeutic effect for recovery of swallowing function, which is worth extending.
