Risk factors of polycystic ovarian syndrome among Li People

Objective: To study the relevant risk factors of polycystic ovarian syndrome (PCOS) of Li People so as to provide basis for early diagnosis and treatment of PCOS. Methods: With case-control study method, 285 cases of PCOS of Li People were as recruited case group, and 580 cases of non-PCOS of female Li People as control group. Questionnaire was adopted to collect data regarding risk factors of PCOS, then the risk factors of PCOS was searched by univariate and multivariate analysis. Results: Multivariate analysis showed that the risk factors of PCOS included in menstrual cycle disorder (OR = 5.824), bad mood (OR = 2.852), family history of diabetes (OR = 7.008), family history of infertility (OR = 11.953), menstrual irregularity of mother (OR = 2.557) and lack of physical exercise (OR = 1.866). Conclusions: To target the high risk factors of menstrual cycle disorder, family history of diabetes, family history of infertility, family history of diabetes, bad mood and lack of physical exercise of female population, we should implement early screen, diagnose and treatment of POCS in order to reduce the incidence rate of PCOS and improve prognosis of PCOS.

Comparison on serum biomarkers for anovulatory and ovulatory dysfunctional uterine bleeding in Lizu females

OBJECTIVE@#To screen, identify, and compare the serum biomarkers between anovulatory dysfunctional uterine bleeding (ADUB) and ovulatory dysfunctional uterine bleeding (ODUB) in Lizu females.@*METHODS@#The subjects included 128 ADUB patients, 63 ODUB patients, and 93 controls. The serum and supernate of the subjects' mense were collected and stored at -80 °C until use. Differential proteins in the sera of three groups were screened using surface-enhanced laser desorption ionization time-of-flight mass spectrometry. The screened proteins were then identified by tricine-SDS-PAGE gel and spectrometry. Protein expression levels in the menses of ADUB, ODUB, and control subjects were determined using ELISA, RT-PCR, and Western blotting. SPSS 14.1 was used for statistical analysis and chart drawing (α = 0.05).@*RESULTS@#Three differential protein peaks with peak values of 11.80, 13.59, and 14.68 km/z were screened and identified as serum amyploid protein A (SAA), vascular endothelial growth factor, and vitamin K epoxide reductase, respectively. The SAA was highly expressed in the menses of ADUB and ODUB patients but poorly expressed in the controls. The vascular endothelial growth factor was highly expressed in the menses of ODUB and controls but poorly expressed in ADUB patients. Meanwhile, the vitamin K epoxide reductase was highly expressed in the menses of ADUB and control subjects but poorly expressed in ODUB patients.@*CONCLUSIONS@#The SAA is the common serum biomarker of ADUB and ODUB. ADUB may be related to angiogenesis impairment, whereas ODUB may be associated with blood coagulation disruption.

Estrogen up-regulates MMP2/9 expression in endometrial epithelial cell via VEGF-ERK1/2 pathway

OBJECTIVE@#To study the effect of estrogen on anovulatory dysfunctional uterine bleeding (ADUB).@*METHODS@#Primary endometrial epithelial cells of Hainan Lizu female was cultured and hydrolytic activity of gelatinase was determined by gelatin zymography analysis. Cellular mRNA and protein synthesis was blocked respectively to determine whether the increased expression of MMP-2/9 was induced by estrogen. The expression of VEGF was blocked by siRNA. After treatment with various factors, MMP-9, VEGF, total Erk and phosphorylated Erk expression in primary uterine epithelial cells was detected by Western blotting analysis. Cell MMP-2/9mRNA levels was measured by real-time RT-PCR.@*RESULTS@#The activity and expression of MMP2/9 was increased in the endometrium of patients with ADUB. Estrogen could up-regulate the expression of VEGF and activate Erk 1/2-Elk1 signal path. After interference by siRNA, ERK1/2 pathway was blocked in cells, and the expression of MMP-2/9 was down-regulated. ERK1/2 specific blocker U0126 blocked ERK phosphorylation, and it could down-regulate the expression of MMP-2/9.@*CONCLUSIONS@#The results showed that the estrogen can increase the expression of VEGF, and thus activate ERK1/2 pathway to induce MMP-2/9 expression.

Primary human hepatocyte transplantation in the therapy of hepatic failure: 2 cases report

Liver failure is the end stage of hepatopathy with unfavorable prognosis. In two patients with liver failure, viable primary human hepatocytes, obtained from resected liver tissue of patients with hepatolithiasis, were transplanted into the spleen by interventional therapy through femoral arterial cannula. After transplantation, the patients' clinical symptoms and liver function were significantly improved. However, their bilirubin increased within six days following transplantation. One suffered from hepatic coma and give up treatment and the other patient died fourteen days after transplantation. It is technically safe to treat liver failure by intrasplenic transplantation of adult hepatocytes and the clinical efficacy has been confirmed. How to make transplanted hepatic cells proliferate and functionally survive is the key point to maintain continuous improvement of the recipient's hepatic function.

Application of immunohistochemical labeling in the diagnosis of hepatobiliary intraepithelial neoplasia and/or cancer / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the best combination of monoclonal antibodies for the diagnosis of hepatobiliary intraepithelial neoplasia and/or cancer.</p><p><b>METHODS</b>CK7, CK20, Villin, CEA, P53 and Ki-67 antigens were detected in the tissues of high-level hepatobiliary intraepithelial neoplasia and cancer by immunohistochemistry and the results were analyzed statistically.</p><p><b>RESULTS</b>Villin was 100% positive in hepatobiliary intraepithelial neoplasia and/or cancer, while 100% negative in the adjacent normal bile duct epithelium. The expression rate of CEA was significantly lower in high-level hepatobiliary intraepithelial neoplasia tissues than in the cancer tissues (P<0.05). Ki-67 indexes were significantly lower in most of the high-level hepatobiliary intraepithelial neoplasia than in the cancer tissue (P<0.01). P53 indexes were also lower in high-level hepatobiliary intraepithelial neoplasia (P<0.01).</p><p><b>CONCLUSION</b>Detection of multiple antigens (CEA, Villin, Ki-67 and P53) provides specific clues to the diagnosis of high-grade hepatobiliary intraepithelial neoplasia and/or cancer.</p>
