BACKGROUND:Recently, the biodegradable materials with good biocompatibility and with no adverse reaction have been widely applied in the clinical treatment and care of gynecology and obstetrics. The development of the biodegradable material is very rapid. OBJECTIVE:To summarize the application of biodegradable materials in gynecology and obstetrics. METHODS: The first author searched PubMed and CNKI databases for articles related to biodegradable materials in gynecology and obstetrics using the keywords of “degraded materials, biodegradable materials, gynecological care, surgery” in Chinese and English respectively. This article has an outlook of the potential application in gynecology and obstetrics based on clinical experience. RESULTS AND CONCLUSION:Biodegradable materials with good biocompatibility and biological security play an important role in biomedical materials. Their polymers and degradation products show smal adverse reactions to the body, and have good biomechanical properties, physical and chemical properties and good workability, which have been widely used in gynecology and obstetrics, such as absorbable stylolite and tampon tape. Although we have made a great progress on the biomaterial research, it stil has the limitation and safety flaws in the clinic. As the biomaterial research is further developed, the biomaterial application prospect wil be more promising.

(0.05)).And there were no side effects in two groups. CONCLUSION: The Yinqiao Tablet is effective and safety in treating wind-type common cold.

Objective To investigate the effect of ethanol on level of the main hippocampal subtype of muscarinic receptor(M1)in mice,and evalu?ate whether the content change on this receptor could be linked with alterations in cognition,so as to further reveal the mechanism of brain damage in?duced by ethanol. Methods Sixty female mice were randomly divided into four groups. The model mice were induced by intragastric administration of ethanol at dose of 8%,16%,and 32%respectively of 0.2 mL/10 g for 8 weeks according to the protocol,and control group were treated with intra?gastric administration of distilled water. The capability of learning and memory were examined by Morris water maze,and ELISA method was used to measure the M1 receptor content in hippocampus in each group of mice. Results Compared with first day,the mean escape latency period on the fifth day was significantly shortened in each group. There was no significant difference between ethanol and control group for the mean escape latency period on the fifth day. Compared with the control group,the active time in the target quadrant was significantly shortened in 16%and 32%ethanol group. M1 receptor content in hippocampus formation was significantly decreased in all the ethanol group mice. The ethanol concentration was nega?tive correlated with the M1 receptor content. Conclusion Chronic alcoholism can induce the memory impairment in mice,which might be associat?ed with the low level of M1 receptor subtype in hippocampus of mice.

Objective To detect UGT1A1 gene promoter polymorphism with gene sequence method and analyze the distribu-tion of UGT1A1*28 and UGT1A1*6 gene polymorphism in Wuhan.Methods A total of 230 samples were collected from tumor patient in Medical Oncology Department of Renmin Hospital of Wuhan University from January 2013 to December 2014,then gene sequence of the target fragments were detected by Sanger sequencing method and analyzed patient UGT1A1 gene promoter polymorphism TA box.Results In this research examination 230 example tumor patient,198 patients (86.1%)were identified with TA6/TA6 genotype,29 patients (12.6%)were identified with TA6/TA7 genotype,3 pa-tients (1.3%)TA7/TA7 variant.Conclusion TA6/TA6 wild-typewas higher frequence in patients with malignant tumour in Wuhan.

Objective To evaluate the clinical effects and safety of Er:YAG fractional laser for facial rejuvenation.Methods Altogether 559 patients aged from 32 to 58 years old with obvious pigmentary lesions and wrinkles in the face were given 2 courses of restoration treatment with the Pixel Er:YAG fractional laser.The patients paid a return visit a month later after the last treatment.With the results of clinical observation and photograph-based comparison,the therapeutic effects were graded by disappearance of pigmentary lesions and elimination of facial wrinkles.Complications such as hyperpigmentation,depigmentation and hyperplastic scar were observed.Results Among the 559 patients, there were 103 cases (18.4%) of slight effect, 378 cases (67.6%) of moderate effect, and 78 cases (14%) of excellent effect,with the total effective rate of 100% and a satisfactory rate of 81.6%.The was no complication such as hyperpigmentation,depigmentation and hyperplastic scar occurred.Effective maintaining rate within 6 months was 67%.Conclusion Er:YAG fractional laser is safe and effective for facial rejuvenation and worthy of promotion.

Background and purpose:Promoter methylation ofPCDH10, a gene encoding protocadherin 10, has been found to be correlated to poor prognosis in gastric cancer (GC) patients. However, the relationship between the expression of PCDH10 and prognosis in GC remained unknown. This study aimed to explore the relationship be-tween the expression of PCDH10 and clinicopathological features and prognosis of GC, and to identify biomarker for predictions of recurrence and survival of GC.Methods:mRNA expressions of PCDH10 in 115 pairs of GC tissues and adjacent normal tissues were detected by real-time lfuorescence quantitative polymerase chain reaction (RTFQ-PCR). The correlation between PCDH10 expression level and clinicopathological features and prognosis of GC was analyzed. Prediction models for 5-year recurrence and 5-year survival were established using logistic regression method.Results:Progression-free survival (PFS) and overall survival (OS) were signiifcantly prolonged in patients with PCDH10 low expression compared to patients without PCDH10 low expression (P=0.046 andP=0.033 respectively). PCDH10 low expression signiifcantly correlated with less lymph node metastasis (P=0.001) and earlier TNM staging (P=0.001), and was more common in female than in male (P=0.040). The mRNA expression of PCDH10 did not correlate with age, Lauren classiifcation, T stage, neural invasion or vascular invasion. Univariate Cox analysis showed Lauren classiifca-tion, T stage, N stage, M stage and PCDH10 expression signiifcantly correlated with PFS and OS. Logistic regression models for the prediction of 5-year recurrence or 5-year survival based on clinicopathological features included Lauren classiifcation, T stage, N stage and M stage as variables. Logistic regression models for the prediction of 5-year recur-rence or 5-year survival based on PCDH10 expression included Lauren classiifcation, T stage, M stage and PCDH10 expression level but not N stage as variables. The models based on PCDH10 expression had the same effciencies as models based on clinical parameters in predicting 5-year recurrence or 5-year survival for GC patients.Conclusion:PCDH10 low expression correlated with better prognosis, less lymph node metastasis and earlier TNM stage in GC patients. Low expression of PCDH10 may be a biomarker of better survival for GC patients. Logistic regression model based on PCDH10 mRNA expression may serve as a prediction model when patients have unknown lymph node metas-tasis status.
