Objective To study the protective effect of leuprorelin particle on ovarian reserve function applied before the laparoscopic cystectomy of ovarian endometriosis.Methods 106 patients with endometriosis treated from January 2015 to December 2015 in our hospital were selected.The subjects were divided into two groups according to the random number table, 53 cases of each group.The control group adopted the laparoscopic surgery;the observation group took the leuprorelin particle before the laparoscopic surgery.The operation condition, ovarian hormone and function were observed. Results The operation time and bleeding amount in observation group was better than control group ( P <0.05 ) .After surgery, the exhaust time between two groups had no significantly different.After surgery, the level of follicle stimulating hormone (FSH) in observation group was lower than control group; the level of estradiol (E2) in observation group was higher than control group (P <0.05); the level of luteinizing hormone (LH) between two groups had no significantly different.After surgery, the ovarian volume and antral follicle count ( AFC) in observation group was better than control group (P<0.05).Conclusion Before the laparoscopic cystectomy of ovarian endometriosis, the leuprorelin particle protects the ovarian function and morphology and has less impact in the level of hormone.

BACKGROUND: Umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs) have been shown to lead to new tissue formation after homing and engrafting to the heart. But the safety of UCB-MSCs engrafting remains to be further investigated. OBJECTIVE: To study the safety and apoptosis inhibition of the UCB-MSCs under co-culture conditions on human cardiomyocytes. METHODS: UCB was collected at delivery with informed consent obtained from 10 donors. The UCB-MSCs were treated with 5-azaserine to induce differentiation into cardiomyocytes. The in vitro cultured cells of the 3rd-5~(th) passages and dividing cells were taken to detect telomerase activity, tumor-related gene expression, G-banding patterns of chromosomal karyotupes, cell surface antigen expression, tumor formation in nude mice, and inhibited apoptosis under co-culture conditions. RESULTS AND CONCLUSION: Prior to and after 5-azaserine induction, telomerase activity and tumor-related gene expression (p53, cyclin A, cdk2, β-actin, C-fos, h-TERT, c-myc) of UCB-MSCs were similar, no abnormal chromosomal karyotupes were observed, immunophenotype exhibited no change, CD34 was negative, but CD44 and CD90 (Thy-1) were positive. At 10 weeks after inoculation of UCB-MSCs, nude mice still survived healthily and no formed tumor in vivo was observed. Hematoxylin-eosin staining suggested normal subcutaneous tissue. Compared with simple cardiomyocytes, UCB-MSCs could significantly inhibit cardiomyocyte apoptosis under co-culture conditions (P < 0.05), indicating that human UCB-MSCs are a valuable, safe, and effective source of cell transplantation treatment.

OBJECTIVE:To explore the treatment effect and complication prevention of various stent materials for intracranial arteriostenosis.METHODS:A computer-based online search of Science Direct and Ei database (1998-01/2009-10) was performed for English articles with the key words of "intracranial arteriostenosis,stent placement" In addition,CNKI and CBM database (1998-01/2009-10) were searched for related Chinese articles with the same key words in Chinese.Moreover,related works were manually searched.Studies regarding various stent materials for intracranial arteriostenosis were included,including basic and clinical experiments.RESULTS:Multicenter studies of worldwide show that stent implantation displays obvious advantages in treating carotid artery stenosis compared with carotid endarterectomy.Recently,with developing of balloon and stent compliance,as well as stent technology,and application of various novel materials and cerebral protection device,stent has become a safe and effective therapy for intracranial arteriostenosis.However,complications following stent implantation,such as restenosis,ischemic stroke,cerebral hemorrhage hypertransfusion syndrome,and cerebral angiospasm,limit its application.CONCLUSION:The safety and efficacy of intracranial stent implantation remains validation of multicenter and perspective studies.High incidence of restenosis following stent implantation requires further improvement.

Abdominal wall endometriosis (AWE) is defined as endometrial tissue superficial to the peritoneum. Many cases of AWE are associated with cesarean section scars. Thus, AWE is often misdiagnosed as a hernia or hematoma. The most common presentation of AWE is the development of a painful mass after uterine surgery. Many patients with AWE are associated with a previous surgical incision. Careful history and physical examination is essential to make correct diagnosis. Studies such as ultrasound, CT, MRI, and FNA are helpful. Medical treatment of AWEs is usually unsuccessful. Therefore, surgical treatment should be offered to every patient and the results usually are excellent. We performed a review of published literatures to demonstrate the pathogenesis, symptoms, diagnosis, treatment and outcomes of patients having AWE.

OBJECTIVE:To investigate the correlation of serum resistin and adiponectJn Ievels with bone mineral density(BMD)in 232 healthy male volunteers in Changsha area.METHODS:A totaI of 232 healthy Chinese men of Han population were selected randomly from Changsha area.All subjects gave their informed consent to participate in this study.Subjects were excluded from the study if they had conditions or received treatment that affecting bone metabolism.Serum adiponectin and resistin levels were determined by ELISA.BMD was measured by dual energy X-ray absorptiometry in total body,lumbar spine,and total hip.Body fat mass and lean body mass were measured by the whole body scanning.The correlation of serum adiponectin and resistin levels with fat mass and BMD at various sites were analyzed;the predictors of BMD at various sites was assayed using multiple linear stepwise regression analysis.RESULTS:Adiponectin was negatively correlated with fat mass(r=-0.216.P＜0.05),while resistin had no correlation with fat mass.The correlation disappeared after adjustment for age and fat mass(r=-0.006,P＞0.05).The significant negative correlations between adiponectin and BMD were found,and remained significant after adjustment for age and fat mass.There was no correlation between resistin and BMD at various sites.In the multiple linear stepwise regression analysis.adiponectin was an independent predictor of BMD in men.CONCLUSION:Resistin js not correlated with fat mass and BMD at various sites.Adiponectin is correlated with fat mass,and has a negative correlation with BMD at various sites,it is an independent predictor of BMD in Chinese men.

BACKGROUND:Compared with the bone marrow mesenchymal stem cells (BMSCs),cells from the umbilical cord blood (UCB)are considered"very young",and its proliferation and differentiation cannot decrease with age.Thus,cells from UCB are a great substitute of BMSCs.OBJECTIVE:To observe the characteristics of in vitro differentiation of UCB-MSCs into cardiomyocytes.DESIGN,TIME AND SETTING:The observational experiment was performed at the Beijing Sijitan Hospital from March 2005 to February 2007.MATERIALS:Cells from UCB were collected from healthy arturients after signing the informed consent.METHODS:Mononuclear cells were isolated to further harvest MSCs.At the third passage,CD34,CD44 and CD90 were measured using immunofluorescence flow cytometry.After 4 weeks of 5-azacitidine treatment,myosin heavy chain,GATA4 and troponin 1 were identified using immunohistochemistry and reverse transcription-polymerase chain reaction.MAIN OUTCOME MEASURES:β-myosin heavy chain,GATA4 and troponin I expression.RESULTS:UCB-MSCs showed a fibrolast-like morphology,clonally expanded after 5-azacitidine reatment.The immunophenotype of these clonally expanded cells is consistent with that reported for BMSCs.Immunohistochemistry and reverse transcription-polymerase chain reaction showed β-myosin heavy chain,GATA4 and troponin I expression.CONCLUSION:UCB-MSCs differentiate into cardiomyocyte-like cells,which have the characteristics of cardiomyocytes.

Objective　To investigate the early changes and clinical significance of plasma endothelin(ET) and nitric oxide(NO) in patients with acute brain injury.　Methods　The plasma ET and NO concentration at 1 day after injury were checked with radioimmunoassay and Green method in 48 cases of acute brain injury, in 42 cases of non-brain injury and in 38 healthy volunteers. 　Results　 The early plasma concentrations of ET and NO were (109.73±12.61) ng/Lf and (92.82±18.21) μmol/L, respectively, in 48 cases of acute cerebral injury, which were higher than those in the non-brain injury group［(67.90±11.33) ng/L and (52.66±12.82) μmol/L, respectively, P<0.01］ and in the normal control group ［(50.65±17.12)ng/L and (36.12±12.16) μmol/L, respectively, P<0.001］. The amounts of ET and NO in the patients with severe brain injury were (116.18±18.12) ng/L and (108.19±13.28) μmol/L, respectively, which were significantly higher than that of the moderate brain injury group［(92.33±16.32) ng/L and (76.38±12.71) μmol/L, respectively, P<0.01］.The early levels of ET and NO were negatively related to the GCS scores of the patients with acute brain injury. The amounts of ET and NO were (126.23±15.23)ng/l and (118.18±10.12) μmol/L, respectively, in the patients with subdural hematomas, which were significantly higher than those in the patients with epidural hematomas ［(81.13±12.37) ng/L and(68.02±13.18) μmol/L, respectively, P<0.01］. The stable plasma concentrations of ET and NO at 14 days after injury in the patients with acute brain injury and with non-brain injury were similar to that in the normal controls. 　Conclusions　 ET and NO are related to the pathophysiological process in the early period of acute brain injury, and the values of ET and NO correlate positively with the clinical manifestations. The changes of plasma ET and NO can be regarded as important indexes to diagnose the severity of acute brain injury.

Objective　To measure the levels of urokinase-type plasminogen activator (uPA) and its receptor (uPAR) in synovial fluid and plasma of patients with RA and investigate its clinical significance.Methods　By using ELISA sandwich method,the levels of uPA and uPAR in plasma from 46 patients with RA and 8 with osteoarthritis (OA) were measured.Those in synovial fluid (SF) from 14 patients with RA,and plasma from 12 healthy subjects were measured as controls.Results　The concentration of uPA and uPAR in SF from patients was significant higher than that in their plasma (P＜0.001,P＜0.01),and the concentration of uPA and uPAR in plasma of RA was also much higher than that in plasma of OA patients (P＜0.05,P＜0.000 1) and healthy subjects (P＜0.000 1,P＜0.001).There was no significance between plasma levels of RF＋ and RF－ in RA patients.The concentration of uPA and uPAR of plasma in RA correlated positively with CRP,RF and the number of swelling joints.Conclusion　The levels of uPA and uPAR in SF and plasma are useful parameters for monitoring disease activity of RA.These findings suggest that the uPA and uPAR genes may play an important role via proteolytic damage of the extracellular matrix during the development of RA.
