Objective:To observe the effect of Wenyang Huazhuo recipe (WYHZ) on pregnancy outcomes in patients with unexplained recurrent spontaneous abortion (URSA).Methods:A retrospective cohort study was used and 240 cases of pregnancy URSA patients with spleen kidney yang deficiency syndrome at the Reproductive Center, First Teaching Hospital of Tianjin University of Traditional Chinese Medicine and Department of Gynaecology and Obstetrics, General Hospital of Tianjin Medial University from November 2018 to March 2022 were recruited. The patients were assigned to WYHZ group (120 cases) and control group (120 cases) based on whether accepting oral WYHZ from 3 months before pregnancy to 8-12 weeks after pregnancy regularly. Pregnancy outcomes, perinatal period outcomes and obstetric complications were compared between the two groups. Multivariate logistic regression were used to analyze the effect of WYHZ on pregnancy outcome.Results:The live birth rate and the clinical pregnancy rate in WYHZ group [86.67% (104/120), 90.00% (108/120)] were higher than those in control group [71.67% (86/120), P=0.004; 75.00% (90/120), P=0.002]. The early abortion rate in WYHZ group [10.08% (12/119)] was lower than that in control group [25.86% (30/116), P=0.002], the differences were statistically significant. There were no significant differences in perinatal outcome and incidence rate of obstetric complications between the two groups (all P>0.05). Multivariate logistic regression analysis showed that the application of WYHZ significantly improved the live birth rate ( OR=8.818, 95% CI: 3.556-21.871, P<0.001) and sustained pregnancy rate ( OR=11.261, 95% CI: 4.262-29.751, P<0.001) in URSA patients. Conclusion:WYHZ using before and during pregnancy can significantly improve the live birth rate and the clinical pregnancy rate of URSA patients with syndrome of yang deficiency of spleen and kidney, and improve their pregnancy outcomes.

Objective To investigate the efficacy and safety of ALA-PDT combined with Quxietang douc-hing in the treatment of cervical HPV infection.Methods 208 female cervical PCR-HPV positive patients were randomly divided into treatment group and control group,each group had 104 cases.The control group received 10%(ALA)in cervical for 3 hours,then red light for 30 minutes once a week,a total of 3 times.Treatment group was given 10% (ALA)in cervical for 3 hours,then red light for 30 minutes once a week,a total of 3 times,and douching vagina with Quxietang,one day at a time,stay 3 weeks.After treatment for 3 months,every month,a cervical PCR-HPV check was conducted,summarized virus removal efficiency.Results The virus removal efficiency of treatment group was 89.42%,that of the control group was 73.08%,the difference was statistically significant (χ2 =7.471,P<0.05 ).The patients in the treatment group had light local mild erythema,swelling,burning pain,without treatment subside.Conclusion ALA -PDT combined with Quxietang douching method is efficient,with mild adverse reactions,the treatment group was better than the control group in removing cervical HPV infection and effectively eliminating the hidden trouble of cervical HPV.

Objective: To investigate β2 adrenergic receptor (β2-AR) gene polymorphism, Arg16Gly, Gln27Glu and essential hypertension (EH) occurrence in Tibetan population living at high altitude area. Methods: Our research included in 2 groups: EH group, n=385 patients and Control group,n=297 normal healthy subjects. β2-AR polymorphisms of Arg16Gly and Gln27Glu were detected by Snapshot mini-sequencing technique and their frequencies were compared between 2 groups and male, female genders. Results: The genotype and allele frequency distributions of Arg16Gly and Gln27G1u were similar between 2 groups, P>0.05; there were no signiifcant differences between male and female genders,P>0.05. Conclusion: No obvious relationship was found between β2-AR gene polymorphism (Arg16Gly, Gln27Glu) and EH occurrence in Tibetan population living at high altitude area.

Objective To explore the prevalence,awareness,treatment and control rates of hypertension among Tibetan monks in Gannan Tibetan Autonomous Prefecture of Gansu Province,and to analyze risk factors of hypertension in this population.Methods A total of 984 (aged 18 and over) Tibetan monks in Gannan Tibetan Autonomous Prefecture of Gansu Province were included with cluster sampling method from March to June,2014.General information was obtained by questionnaire and blood pressure was measured.Multivariate logistic regression analysis was applied to analyze the risk factors of blood pressure.Results Prevalence of hypertension in this population was 19.3％ (190/984),and standardized prevalence rate was 21.7％.The prevalence of hypertension were 16.3％ (82/502),21.0％ (60/286) and 24.5％ (48/196),and standardized prevalence rate was 17.8％,22.1％ and 26.6％ among Tibetan monks aged 18-39,40-59 and ≥60 years,respectively.Rates of awareness,treatment and control of hypertension in Tibetan monks were 9.5％ (18/984),4.2％ (8/984)and 1.6％ (3/984),respectively.Multivariate logistic regression analysis showed that age,body mass index and family history of hypertension were independent risk factors of hypertension in this population (P ＜ 0.01 or 0.05).Conclusions Prevalence,awareness,treatment and control rates of hypertension among Tibetan monks in Gannan Tibetan Autonomous Prefecture of Gansu Province are relatively low.Age,body mass index and family history of hypertension are risk factors of hypertension in this population.

BACKGROUND:Previous studies have confirmed that healing of in vivo tendon is the outcome of interaction between endogenous healing and exogenous healing. Exogenous healing is a main reason for tendon adhesion, and affects the recovery of tendon function.OBJECTIVE: To explore application of tissue engineering technique and its materials in prevention and treatment of tendon adhesion induced by movement injury.METHODS: Using the key words of "movement injury, biomaterial, tissue engineering, tendon adhesion", we retrieved randomized animal controlled studies and clinical application literatures addressing tendon biomechanics function, adsorbable biomaterial polyglycolic acid, tendon cells-constructed tissue engineered tendon in vitro, biomembrane, chitosan, adsorbable antistick membrane, sodium hyaluronate, bioprotein gel and so on in prevention of tendon adhesion in Chinese Journal Full-text Database published from January 1990 to December 2000. By aggregate analysis of literature data, follow-up and function evaluation, this article summarized clinical application of tissue engineered techniques and materials in prevention of tendon adhesion.RESULTS AND CONCLUSION: A total of 61 literatures were primarily obtained. Following reading titles and abstracts, 31 literatures of irrelevant objectives and contents, and 9 literatures of repetitive contents were excluded. Totally 21 literatures were included for analysis. Tendon adhesion refers to hyperplasia and invasion of surrounding tissues during repair of tendon damage. With the deep understanding of tendon repair healing, application of tissue engineering to preventing tendon adhesion became more and more. Tendon healing is an interaction between endogenous healing and exogenous healing, and mainly endogenous healing, which was simultaneously associated with tendon sheath, vincula tendinum and synovial fluid. Tendon adhesion is mainly induced by excessive action of exogenous healing and damage to surrounding tissues. Tissue engineering is a novel technique. Novel biomaterials are widely used in tissue engineering performance to solve problems such as tendon injury andchondronecrosis. Presently, it Is important to reconstruct tissues, which can reach clinical outcomes of preventing adhesion.
