Objective To study the different expression of microRNA(miRNA) including mir-29c,mir-200a,mir-145 in the mid-secretary endometrium and its relationship with infertility of endometriosis.Methods From August 2011 to February 2013,36 infertile cases with endometriosis confirmed by laparoscopy and pathology and excluded the other infertile factors in Department of Reproductive Medicine in Peking University Shenzhen Hospital were enrolled in this study,which were divided into 17 cases with stage Ⅰ-Ⅱ,19 cases with stage Ⅲ]-Ⅳ according to the revised classification American Fertility Society.Forty-four healthy women with male factor infertility were chosen as control group.The relative expression levels of mir-29c,mir-200a,mir-145 in the endometrium of women in two groups were detected by using real-time quantitative polymerase chain reaction.Those women were followed up for pregnancy outcome of endometriosis group after assisted reproductive techniques (pregnancy and nonpregnancy group respectively).Results (1) The expression of miRNA between endometriosis and control groups:the average expression level of mir-29c,mir-200a,mir-145 in the endometrium of endometriosis group was 2.46 ± 1.98,3.20 ± 2.45,6.378 ± 3.275,which were significantly higher than 1.36 ± 1.05,2.04 ±1.16,4.548 ± 1.885 in control group (P =0.026,0.027,0.041,respectively).(2) The expression of miRNA between Ⅰ-Ⅱ stage and Ⅲ-Ⅳ:the average expression level of mir-29c,mir-200a,mir-145 in the endometrium was 0.53 ± 0.51,0.33 ± 0.26,0.048 ± 0.021 in patients with of stage Ⅰ-Ⅱ,while 0.26 ±0.18,0.28 ±0.12,0.045 ±0.016 in stage Ⅲ-Ⅳ respectively,there were no statistically significant differences between the two groups(P =0.191,0.661,0.753,respectively).(3) The expression of miRNA between pregnancy and non-pregnancy groups:the average expression level of mir-29c,mir-200a,mir-145 in the endometrium were 0.60 ± 0.30,1.23 ± 0.48,0.886 ± 0.238 in pregnancy group,while 2.64 ± 1.73,4.39 ± 2.58,7.199 ± 3.945 in non pregnancy group,there were statistically significant differences between the two groups(P =0.030,0.039,0.028,respectively).Conclusion Up-regulation of mir-29c,mir-200a,mir-145 in the endometrial tissue might play a role in endometriosis associated infertility.

BACKGROUND: Studies have shown that alanine (A) to threonine (T) substitution at codon 54 of intestinal fatty acid-binding protein (FABP2) in different populations is associated with dyslipidemia and other characteristics of metabolic syndrome.OBJECTIVE: To investigate the frequency of encoding 54Ala/Thr (A/T) single nucleotide polymorphism in the FABP2 in middle-aged and old people, and explore the association between 54T FABP2 and plasma lipids.DESIGN: A case-controlled analysis. SETTING: Department of Biochemistry, Hebei North University and Department of Clinical Laboratory, the 251 Hospital of Chinese PLA.PARTICIPANTS: 469 physical examinees were selected from the Medical Examination Center, the 251 Hospital of Chinese PLA between October 2003 and April 2005. The subjects included 217 males with mean age of (56±10) years, and 252 females with mean age of (55±13) years. Only people with normal liver and kidney function, and with no blood relation were recruited. The informed consent to this study was obtained from all subjects. The experiment was admitted by Hospital Ethics Committee. METHODS: ①After fasting for 12 hours, automatic analyzer (Olympus AU 6400) was adopted to measure plasma total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), apoprotein A1(Apo A1) and Apo B levels. ②1 mL venous blood was extracted and immediately mixed with anti-coagulants containing citric acid, natrium citricum and glucose. White blood cells were separated and genomic DNA was isolated using standard methods with proteinase K digestion and phenol/chloroform purification. The genotype distribution frequency in each group was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). MAIN OUTCOME MEASURES: ①Plasma TC, TG, HDL-C, LDL-C, Apo A1and Apo B levels; ②Distributions of FABP2 genotypes at codon 54. RESULTS: ①The genotype frequencies of A/A, A/T, T/T were 0.48, 0.42, and 0.10 in males, and 0.44, 0.46, and 0.10 in females, respectively. The allelic frequency of point mutant 54Thr in FABP2 gene was 0.31 in males and 0.33 in females, respectively. There was no difference between males and females (χ2=0.47, P > 0.05). ②The LDL-C and Apo B concentrations in fasting plasma of males with 54T allele were significantly higher than those with 54A allele (P < 0.05). The TC and LDL-C concentrations in fasting plasma of females with 54T allele were significantly higher than those with 54A allele (P < 0.05). CONCLUSION: In the middle-aged and old populations, the frequency of encoding 54Ala/Thr polymorphism in FABP2 gene is not correlated with gender, but with high lipoprotein profile.

OBJECTIVETo explore the relationship between body mass index (BMI) and clinical outcomes of in vitro fertilization and embryo transfer (IVF/ICSI-ET) cycles in patients with endometriosis.
METHODSWe retrospectively analyzed the data of infertile women with endometriosis undergoing 244 IVF/ICSI-ET cycles between January, 2011 and August, 2012. The patients, categorized into 3 groups with mild endometriosis, moderate to severe endometriosis, and no endometriosis (control), underwent a long protocol, and the relationship of the general conditions, dose of gonadotropin, days of stimulation, BMI, number of oocytes retrieved and embryos transferred with the outcome of IVF were analyzed.
RESULTSThere was significant difference between moderate to severe endometriosis group and the control group in the number of ampules, oocytes retrieved and embryos transferred. The patients with moderate or severe endometriosis had significantly lower BMI and clinical pregnancy rate than those with mild or no endometriosis.
CONCLUSIONEndometriosis is inversely correlated with BMI, and BMI of the patients with endometriosis may affect the pregnancy rate of IVF cycles.

Objective To observe the effects of electro-acupuncture on loading of lower limb joints in patients with knee osteoarthritis (KOA) during stair climbing and explore the related biomechanical mechanism. Methods Forty patients with KOA were randomly assigned, with 20 patients in observation group (electro-acupuncture group, EA group) and 20 patients in control group (superficial acupuncture group, SA group). Finally 18 patients in each group completed the study. In observation group, seven knee acupuncture points were chosen and patients were connected with electro-acupuncture instrument; while in control group, the electro-acupuncture instrument was connected but not electrified after superficial acupuncture at non-acupoint points. The three-dimensional gait analysis system was used to assess the biomechanical characteristics during stair climbing before and after treatment, including peak vertical force (PFz), vertical impulse (IFz) and symmetry index (SI%). Results After 3 weeks of treatment in EA group, PFz of the right foot during stair ascent and PFz of the left foot during stair descent increased (P<0.05); IFz of both feet during stair ascent and IFz of the right foot during stairs descent significantly decreased (P<0.05); no significant differences were found in SI% of peak and impulse (P>0.05). In SA group, only SI of impulse during stairs ascent increased (P<0.05). There was no significant difference between two groups before and after treatment (P>0.05). Conclusions Electro-acupuncture can effectively improve the joint load capacity and reduce the dynamic cumulative load of patients w
