OBJECTIVETo determine the effect of chemotherapy on ovarian endocrine function and menstruation.

METHODSMenstruation and serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), and estradiol (E2) levels were observed when the patients with ovarian cancer undergoing one side ovarectomy were followed by chemotherapy.

RESULTSAbnormal menstruation occurred in 86.7% cases, including 80% amenorrhea and 6.7% oligomenstruate. Menstruation resumed around 2 months after chemotherapy. Serum LH, FSH levels rose and E2 level declined during amenorrhea. No significant change was observed in progesterone or testosterone levels.

CONCLUSIONSOvary function impairment may occur in ovarian cancer patient treated by one side ovarectomy followed by chemotherapy. Serum LH, FSH, and E2 levels change and abnormal menstruation are two common manifestations. However, chemotherapy-related amenorrhea is reversible.

OBJECTIVETo investigate the effect and mechanism of Compound Salvia injection (CSI) on nitrate ester tolerance.

METHODSEighty-four patients with coronary heart disease (CHD) were randomly divided into three groups, Group A treated with isosorbide dinitrate (ISD, 15 mg, 4 times per day) alone, Group B with ISD plus CSI and Group C with ISD plus vitamin C. The therapeutic course for all groups was 10 days. The tolerance to nitrate ester and blood pressure were monitored. Before and after treatment, the color Doppler ultrasonic apparatus was used to detect the baseline value of humeral arterial internal diameters (D0), the humeral arterial dilatory response under compression [D1, that is, the flow-mediated vasodilation (FMD)] and the vasodilatory response after sucking of nitroglycerin (D2). And the blood levels of endothelin-1 (ET-1), endothelial nitric oxide synthase (eNOS) mRNA expression were determined. The endothelial-dependent vasodilation (EDD) was expressed by (D1 - D0)/D0 x 100%, and the endothelial-independent vasodilation (EID) was expressed by (D2 - D0)/D0 x 100%.

RESULTS(1) The occurrence rate of nitrate tolerance in Group B and C (28.57% and 35.7%) was lower than that in Group A (64.29%), but insignificant difference was found between the former two. (2) After treatment, blood pressure increased in Group A to the level of pre-treatment, that in Group C also increased but still lower than that of pre-treatment, while insignificant increase was observed in Group B, comparison between Group B and C showed significant difference (P < 0.05). (3) After treatment, EID lowered in Group A, EDD increased in Group B and C (P < 0.05), EDD and EID in Group B and C were higher than those in Group A (P < 0.05), and EDD was higher in Group B than in Group C (P < 0.05). (4) After treatment, ET-1 mRNA expression lowered in Group B, eNOS mRNA expression increased in Group B and C, with significant difference as compared with those before treatment and those in Group A (P < 0.05), and eNOS mRNA expression in Group C was lower than that in Group B (P < 0.05).

CONCLUSIONCSI could partially prevent the occurrence of tolerance to nitrate ester, with the effect better than vitamin C, the mechanism might be related with its regulation on eNOS, ET-1 mRNA expression and protection on vascular endothelial function.

OBJECTIVETo compare the clinical values of the model for end-stage liver disease (MELD)-Na scoring system and the Child-Turcotte-Pugh (CTP) scoring system for predicting the short-term prognosis of acute-on-chronic hepatitis B liver failure.

METHODSA total of 339 patients with acute-on-chronic hepatitis B liver failure and admitted to the Eighth People's Hospital of Guangzhou and Nanfang Hospital of Southern Medical University between January 2010 and December 2012 were included in this retrospective analysis. The short-term predictive values of MELD-Na and CTP scores were compared for this patient population.

RESULTSThe mean MELD-Na score in the advanced stage of liver failure was significantly higher than those in the early and middle stages, respectively (both P less than 0.01). The mean MELD-Na score in the middle stage of liver failure was also significantly higher than that in the early stage (P less than 0.01). In contrast, the mean CTP scores for the three stages of liver failure were not significantly different (all P more than 0.05). The MELD-Na score showed a stronger correlation with the stage of liver failure (rs =0.485, P less than 0.01) than did the CTP score (rs =0.306, P less than 0.01). The short-term mortality rates were significantly different for the three stages of liver failure (P less than 0.01). The mean MELD-Na score of the death group was significantly higher than that of the survival group (P less than 0.01). The CTP scores, however, were not significantly different between the death and survival groups (P more than 0.05).The short-term mortality rate of liver failure was significantly higher for patients with increased scores for the MELD-Na and CTP systems (both P less than 0.01). The areas under the curve of the MELD-Na and CTP scores were 0.813 and 0.823, respectively. The MELD-Na and CTP score have similar predictive values (P more than 0.05).

CONCLUSIONThe MELD-Na scoring system is slightly superior to the CTP scoring system for predicting short-term prognosis of acute-on-chronic hepatitis B liver failure.The predictive value may improve for both the MELD-Na score and the CTP score when combined with expert clinical practice and experience.

Objective:To observe the impact of diabetes mellitus (DM)on pacing parameters and postoperative com-plications in patients With implantation of permanent artificial cardiac pacemaker.Methods:A total of 80 patients With sick sinus syndrome,Who received implantation of permanent artificial cardiac pacemaker from Jun 2008 to Jun 2011,Were enrolled.According to complicated With DM or not,they Were divided into DM group (n=40)and non-DM control group (n=40).Pacing parameters and postoperative complications Were compared betWeen tWo groups.Results:There Were no significant difference in atrial and ventricular pacing threshold,sensing and of pace-maker impedance in baseline betWeen tWo groups (P>0.05).All parameters of pacemaker increased in tWo groups after implantation 12 months;compared With non-DM control group,there Were significant increase in pacing threshold [atrial:(0.59±0.23)V vs.(0.67±0.25)V,ventricular:(0.47±0.28)V vs.(0.54±0.35)V],sens-ing [atrial:(2.33±1.16)mV vs.(2.92±1.36)mV,ventricular:(12.21±4.82)mV vs.(12.77±5.36)mV], impedance [atrial:(537.12±115.32)Ωvs.(662.48±235.26)Ω,ventricular:(602.48±222.46)Ωvs.(762.41± 235.38)Ω]of pacemaker in DM group,P<0.05 or <0.01;and incidence rate of postoperative complications (12.5%)in DM group Was significantly higher than that of non-DM control group (5%),P<0.05.Conclusion:Electrocardiographic reconstruction is more severe in SSS patients complicated DM,in these patients postoperative complication incidence significantly elevates.

BACKGROUNDThin endometrium is associated with poor reproductive outcomes; estrogen treatment can increase endometrial thickness (EMT). The aim of this retrospective cohort study was to investigate the factors influencing the effectiveness of estrogen treatment and reproductive outcomes after the treatment in patients with thin endometrium.

METHODSRelevant clinical data of 101 patients with thin endometrium who had undergone estrogen treatment were collected. Possible factors influencing the effectiveness of treatment were analyzed retrospectively by logistic regression analysis. Eighty-seven infertile women without thin endometrium who had undergone assisted reproduction served as controls. The cases and controls were matched for age, assisted reproduction method, and number of embryos transferred. Reproductive outcomes of study and control groups were compared using Student's t-test and the Chi-square test.

RESULTSAt the end of estrogen treatment, EMT was ≥8 mm in 93/101 patients (92.1%). Effectiveness of treatment was significantly associated with maximal pretreatment EMT (P = 0.017) and treatment duration (P = 0.004). The outcomes of assisted reproduction were similar in patients whose treatment was successful in increasing EMT to ≥8 mm and the control group. The rate of clinical pregnancy in patients was associated with the number of good-quality embryos transferred in both fresh (P = 0.005) and frozen-thawed (P = 0.000) embryo transfer cycles.

CONCLUSIONSThinner EMT before estrogen treatment requires longer treatment duration and predicts poorer treatment outcomes. The effectiveness of treatment depends on the duration of estrogen administration. Assisted reproductive outcomes of patients whose treatment is successful (i.e., achieves an EMT ≥8 mm) are similar to those of controls. The quality of embryos transferred is an important predictor of assisted reproductive outcomes in patients treated successfully with exogenous estrogen.
