Objective To explore the relationship between insulin resistance (IR) and benign prostatic hyperplasia (BPH) in elderly men. Methods All BPH outpatients in Geriatric department of the second Xiang Ya Hospital in Feb 2008 were recruited in this study. Bioche assays including insulin (FINS), prostate specific antigen (PSA), HbAlc, fasting plasma glucose, 2 hours postprandial blood glucose were performed and HOMA-IR were calculated. The blood pressure, body weight, height and waist circumference were measured, and the body mass index (BMI) was calculated. Prostate volume (PV) was measured by abdominal ultrasound, lower urinary tract symptoms (LUTS) was evaluated by International Prostate Symptom Score (IPSS) and inquired about the history of LUTS in detail. Results (1) HOMA-IR＞ 2.8 was diagnosed as insulin resistance (IR). The patients were divided into two groups: insulin sensitivity (IS) group (n=48) and IR group (n=20). The PV level was higher in IR group than in IS group [(61.1-32. 9) ml vs. (40.4±16.5)ml, P＜0. 05], there were no statistical differences in PSA [(3.3±2.3) μg/L vs. (2.91±1.3) μg/L, P＞0.05], the history of LUTS [(13.4±6.6)years vs. (8.7±6.0)years, P＞0.05], IPSS [(16.42±6.67)scores vs. (13. 29±7.09)scores, P＞0. 05] between the two groups. (2)According to BPH progressivity evaluation provided by MTOPS study (age≥62 years, PSA≥1. 6 μg/L, PV≥31 ml), the patients were divided into two groups: low progressive risk group (n= 30) and high progressive risk group (n= 38). The FINS and HOMA-IR levels were significantly higher in highprogressive risk group than in low progressive risk group (all P＜0. 01). (3)The PV was positively correlated with HOMA-IR level and FINS level (r= 0. 431, 0. 492, P＜0. 01). Conclusions IR exists in majority of elderly BPH patients, the degree of IR and relative high level of FINS are related to the enlargement of PV and the development of BPH.

Systemic lupus erythematosus (SLE) is an archetypical systemic, autoimmune inflammatory disease , of which the mechanism still not unveiled. Studies on epigenetics in SLE have long been the subject of investigation and as part of epigenetics. DNA methylation has been confirmed to play a role in the pathogenesis of SLE. The high autore-activity of CD4~+ T cell from SLE patients is associated with DNA hypomethylation. DNA hypomethylation is crucial to induce SLE - like autoimmune disease in SLE - non - susceptible mice. The reactivation of inactive X chromosome by hypomethylation may lead to high incidence of SLE in women. Drug - induced SLE is also connected with DNA hypomethylation. To understand the role of DNA methylation in the onset of SLE comprehensively, we review the findings reported in the literatures about DNA methylation and SLE.

ObjectiveTo explore the effect of metabolic syndrome (MS) on the occurrence and development of benign prostate hyperplasia (BPH).Methods 101 elderly BPH patients were divided into two groups:BPH (n = 45) and BPH with MS (n= 56)group.The effects of metabolic indexes,including body mass index (BMI),waist,high density lipoprotein cholesterol (HDL-C),fasting blood glucose (FBS) and insuline resistance index (H()MA-IR),on prostate volume(PV),prostate-specific antigen (PSA),international prostate symptom score (IPSS) and lower urinary tract symptoms (LUTS) were surveyed in BPH patients.Results BPH with MS group showed significantly higher values of PV (t = 3.22,P= 0.003)and longer course of LUTS (t= 2.02,P =0.046) than BPH group.The BPH patients with overweight and obesity had significantly higher levels of PV(49.44±26.83 ml and 51.7±22.2 ml,P=0.021 and 0.043) than BPH patients with normal weight (38.10 ± 10.64 ml).Additionally,BPH patients with abdominal obesity had significantly higher levels of PV than BPH patients without abdominal obesity(50.26±26.51 ml vs.38.99± 11.25ml,P=0.005).BPH patients with low HDL-C had significantly higher PV than BPH patients with normal HDL-C[(54.23±28.92)ml vs.(40.40± 14.87) ml,P=0.009].The values of PV,PSA in the BPH patients with elevated FBS were significantly higher than in BPH patients with normal FBS (t=3.17 and 2.4I,P= 0.035 and 0.013).BPH patients with insuline resistance (IR) had higher values of PV and longer courses of LUTS than BPH patients without IR (t= 3.43 and 3.58,P-0.001).The PV was positively correlated with BMI(r= 0.459.P= O.OOO),FINS (r= 0.42,P=O.OOI),HOMA-IR (r= 0.49,P= 0.003) and gatively correlated with HDL-C (r= 0.38,P-0.000)- Multiple linear stepwise regression analysis showed that PV was closely correlated with HOMA-IR.ConclusionsMS has evident effects on the occurrence and development of BPH.

Objective To evaluate the efficacy of multiple injection of morphine combined with phloroglucinol in the treatment of renal colic. Methods One hundred and twenty patients with severe renal colic were equally divided into three groups by random digits table,with 40 cases each group. The group A was administrated with physiological saline 100 ml and phloroglucinol 80 mg intervenous drop infusion combined with morphine 9 mg intravenous injection fractionated into three times, and the group B was administrated with physiological saline 100 ml and phloroglucinol 80 mg intervenous drop infusion,and the group C was administrated with physiological saline 100 ml intervenous drop infusion and morphine 9 mg intravenous injection fractionated into three times. At 10,20 and 40 min after administration, the antalgic efficacy of three groups were analyzed as well as the side effect. Results At 20 min and 40 min both of the total efficacy rates in group A[82.5%(33/40),95.0%(38/40)] were higher than those in group B [62.5%(25/40),80.0%(32/40)] and group C [60.0%(24/40),77.5%(31/40)] (P＜ 0.05),and the colic-exclusion rate in group A was also higher than that in group B and group C (P ＜ 0.05). The difference of the efficacy rates in group A in these two time-points had no statistical significance (P ＞0.05). No increased pain occurred in group A except 1 case of vomiting. Conclusion Multiple injection of morphine combined with phloroglucinol is quick, effective and safe in the early treatment of renal colic.

Objective : To analyze the prevalence and influencing factors of leprosy reactions in Zhejiang Province from 2010 to 2019, so as to provide reference for the control of leprosy. Methods: Through the national leprosy management system, the new leprosy cases in Zhejiang Province from 2010 to 2019 were recruited to analyze the incidence of leprosy reactions in different demographic characteristics and leprosy clinical features. The multivariate logistic regression analysis was conducted to explore the influencing factors for leprosy reactions. Results : Totally 191 leprosy cases were investigated. The incidence rate of leprosy reactions was 29.32%; the the incidence rate of typeⅠand type Ⅱreaction was 16.75% and 9.42%, respectively. There were 33 leprosy reaction cases (58.93%) before multidrug therapy (MDT) , 13 cases (23.21%) during 0-6 months of MDT, 5 cases (8.93%) during 7-12 months of MDT, 3 cases (5.36%) during over 12 months of MDT, and 2 cases (3.57%) after MDT. The results of the multivariate logistic analysis showed that the cases who were 35 years old or below (OR=2.245, 95%CI: 1.006-5.008) , were not floating population (OR=3.442, 95%CI: 1.394-8.494) , were infected outside family (OR=3.878, 95%CI: 1.075-13.993) and were smear positive (>0+,OR=4.514, 95%CI: 1.365-14.926; >3+,OR=4.727, 95%CI: 1.443-15.485) were risk factors for leprosy reactions. Conclusions The prevalence of leprosy reactions is high in Zhejiang Province from 2010 to 2019, and is associated with age, floating population, source of infection and BI.

Cell growth profiles were evaluated in shake-flask culture to improve sclareol production by the engineered yeast strain Saccharomyces cerevisiae S7. Product formation was tightly coupled with cell growth. High cell density cultures were performed with different carbon sources using a dissolved oxygen level feedback-control strategy in a 3 L bioreactor. The titers of sclareol were 253 mg/L, 386 mg/L and 408 mg/L, respectively, when glucose, ethanol and glucose/ethanol mixture were used as the carbons sources. The maximal titer was 27-fold higher than that obtained under shake-flask culture conditions. The results suggested that the presence of ethanol was beneficial to sclareol production. These results provided useful information for optimization of yeast cell factory and efficient production of terpenoids.
