During 14-17th days, the duodenum of the rat fetus was composed of stratified epithelium and peripheral mesenchyme. On 18th day, the mesenchyme began to protrude toward the basal aspect of the epithelium, resulted in the formation of primary villi. At the sametime, goblet cells and the primordia of intestinal glands appeared. The number of goblet cells,which located at the surface of the villi, increased gradually with the fetus age, whereas after birth the goblet cells decreased with the development and maturation of intestinal glands. From 19th day till 3-4 weeks after birth, the shape of villi changed continuously, and attained to the adult shape in 4th week.

Objective To investigate the clinical significance of the level of adiponectin (APN) in patients with chronic obstructive pulmonary disease(COPD).Methods The case-control study involving APN in OSAHS were searched and identified from Cochrane Library,PubMed,Embase,China Academic Journals Full-text database,VIP Database,and Full text database of China' s.According to inclusion and exclusion criteria,evaluated the quality of choice experiment,and then extracted the valid data for meta-analysis.Results Seven articles were selected,including 2 in SCI,5 in Chinese.Meta analysis showed that APN in acute exacerbation COPD group was significantly higher than in COPD group (standardized mean difference (SMD) =2.32,95％CI=0.62-4.02,P＜0.05).Compared with normal control group,APN in COPD was higher (SMD=1.39,95％CI=1.00-1.78,P＜0.01).Determined publication bias by Begg's and Egger's test,the results did not show any bias (P＞ 0.05).Conclusion The serum APN of COPD patients are significantly elevated,the APN testing in some extent reflect the severity of COPD.

Objective To evaluate the efficacy and safety of domestic human recombinant FSH (rhFSH) in women with anovulation of WHO groupⅡ. Methods A randomized, blind, parallel-controlled, non-inferiority and multicenter study was performed. A total of 534 admitted to 13 hospitals from May 2008 to August 2009. There were 531 women with ovulatory disorder was included in the statistical analysis, were randomly divided into test group (domestic rhFSH, n=352) and control group (imported rhFSH, n=179). Percentage of cycle with mature follicle, ovulation rate, clinical pregnancy rate, multiple pregnancy rate, ovarian hyperstimulation syndrome (OHSS) and adverse events were observed. Results No statistical significant differences (P>0.05) were observed between the two groups in terms of the efficiency on mature follicle [91.8%(323/352) versus 88.8%(159/179)], ovulation rate [91.3%(295/323) verus 90.6%(144/159)], clinical pregnancy rate [19.2%(62/323) verus 18.2%(29/159)], the number of the follicles<14 mm, the level of serum LH and progesterone, the thickness of endometrium on the day of hCG administration. The number of follicle≥18 mm and 14 mm≤follicle<18 mm and the level of serum estradiol on the day of hCG in the test group were significantly higher than those in the control group (P<0.05). The number of days of rhFSH administration in the test group was significantly less than that in the control group [(9.8±2.2) versus (11.4± 0.6) days, P<0.05], the dosage of rhFSH was significantly lower than that in the control group [(879 ± 419) versus (1 043 ± 663) U, P<0.05]. The multiple pregnancy rate in the test group was significantly higher than that in the control group [21% (13/62) versu 10% (3/29), P<0.05]. The incidence of OHSS and adverse events were similar between the two groups (P>0.05), and no other adverse events were observed in test group during treatment. Conclusion Ovarian stimulation with domestic rhFSH is effective, safe and economical in women with anovulation of WHO groupⅡ.

OBJECTIVETo identify the casual mutation of a Chinese pedigree with hypertrophic cardiomyopathy (HCM), and to analyze the genotype-phenotype relationship.

METHODSThe coding exons of 26 reported disease genes were sequenced by targeted resequencing in the proband and the identified mutation were detected with bi-directional Sanger sequencing in all family members and 307 healthy controls. The genotype-phenotype correlation was analyzed in the family.

RESULTSA missense mutation (c.2191C > T, p. Pro731Ser) in the 20th exon of MYH7 gene was identified. This mutation was absent in 307 healthy controls and predicted to be pathogenic by PolyPhen-HCM. Totally 13 family members carried this mutation, including 10 patients with HCM and 3 asymptomatic mutation carriers. The proband manifested severe congestive heart failure and 8 patients expressed various clinical manifestations of heart failure, including dyspnea, palpitations, chest pain, amaurosis or syncope. Five patients were diagnosed as HCM at the age of 16 or younger. One family member suffered sudden cardiac death.

CONCLUSIONSThe Pro731Ser of MYH7 gene mutation is a causal and malignant mutation linked with familiar HCM.
