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 To explore the risk factors of nosocomial infection during the trauma intensive care unit stay and provide reference for clinical prevention.Methods 983 cases of trauma ICU patients were selected, whose clinical data were retrospectively analyzed.And 983 patients were divided into infection group and non-infection group according to their infection status,univariate factors such as age were analyzed aimed at all patients.Infection group was divided into mild traumapatients ( ISS<16 ) and severe trauma patients ( ISS≥16 ) , multivariate factors analysis were carried out aimed at infection group patients and severe trauma patients respectively.Results Independent risk factors of nosocomial infection in infection group patients were age≥60 years ( OR =1.70,95% CI 1.05 ~2.69),time length of ICU stay≥2 weeks (OR=1.59,95% CI 1.06~2.49),tracheacannula(OR=2.69,95% CI 1.80~4.20),ISS score≥16(OR=2.20,95% CI 1.20~3.91),central venousmonitoring(OR=4.31,95% CI 2.81~6.52);independent risk factors of nosocomial infection in severe trauma patients were time length of ICU stay≥2 weeks,trachea cannula,central venous monitoring.Conclusion More than one independent risk factor are related to ICU trauma patients,standardized treatment means,shortening the treatment time and other means should be carried out to control the infection status.

By means of literature investigation and analysis, the papers related to exercise-induced Achilles tendon rupture and operative restoration were summarized, which provide evidences for further analysis. Results demonstrated that exercise-induced Achilles tendon rupture was associated with anatomic structure and local affection of Achilles tendon, as well as athletic techniques. Operative therapy was recommended when the Achilles tendon was completely ruptured. With the development of tissue engineering tendon, more and more biological patch materials have been used in the clinical repair of Achilles tendon due to the superiority on the prevention of postoperative adhesion and the substitution of Achilles tendon.
