Objective To investigate the serum C-reactive protein (CRP) level in patients with acute cerebral infarction and acute massive cerebral infarction with multiple organ dysfunction syndrome (MODS),and analyze the clinical value of CRP. Methods The serum CRP level of 50 patients of control group and 50 patients of cerebral infarction admitted to hospital within 7 days (30 patients were admitted into acute cerebral infarction group and 20 patients into acute massive cerebral infarction with MODS group) were determined by immune scatter turbidimetry. Results (1)In cerebral infarction patients,serum CRP level in 48 cases(96%) was equal and over 5 mg/L.In control group,serum CRP level in 3 cases(6%) was equal and over 5 mg/L(P＜0.0 5).(2)The level of serum CRP acute in cerebral infarction group and in acute massive cerebral infarction with MODS group increased significantly than that in control group (P＜0.01).The level of serum CRP in acute massive cerebral infarction with MODS group increased significantly than that in acute cerebral infarction group.(3)When the level of CRP＜25 mg/L,the incidence of MODS in patients with acute cerebral infarction was zero.When the level of CRP≥25 mg/L,the incidence of MODS increased gradually with the rise of CRP. Conclusions There is positive correlation between the serum level of CRP and the severity of acute cerebral infarction and the incidence of MODS.CRP is a useful marker in predicting the prognosis of acute massive cerebral infarction with MODS.

The positive ratio is 74 percent using the plate anaerobe culturing device made by author, higher than using common anaerobic box and anaerobic jar.

A bacterial strain which could grow well on the substrate of PAEs as the sole source of carbon and energy was isolated from contaminated sludge in the river of WeiFang in ShangDong province and it was designated as JDC-3. Based on the morphology,biophysical and biochemical properties as well as molecular characteristics,this isolate was preliminarily identified as Delftia sp.. A fragment of phthalate dioxygenase gene was successfully amplified from the genus of Delftia for the first time using a set of degenerate primers. Meanwhile,the degradation capability of JDC-3 was determined by HPLC using DMP as test substrate. The results showed that the optimal pH and temperature were at 7.0～8.0 and 30?C～35?C respectively. The degradation kinetics of JDC-3 was studied in different initial DMP concentration under optimal conditions. The results indicated that the degradation dynamic equation was ln C =-0.06837 t + A when DMP concentration was lower than 300 mg/L,with half life of 12.48 h. The degradation rate decreased and half life of JDC-3 prolonged as the initial concentration kept on increasing.

OBJECTIVETo compare the effect and safety of the no-flip method versus the external method in Shang Ring circumcision.

METHODSWe searched relevant randomized controlled trials published in China and abroad comparing the no-flip method and external method of Shang Ring circumcision. Based on the Cochrane Handbook for systematic review, two reviewers independently eval- uated the quality of the included studies and abstracted relevant data, followed by a meta-analysis using the statistical software Review Manager 5.1.0.

RESULTSTotally 7 studies with 1 200 cases were included. Compared with the external method, the no-flip method was associated with a lower total rate of complications (RR = 0.40, 95% CI: 0.18, 0.87, P = 0.02), a lower incidence of postop- erative edema (RR = 0.28, 95% CI: 0.09, 0.81, P = 0.02), and a lower 24 h postoperative pain score (MD = -0.35, 95% CI: -0.55, -0.14, P < 0.001).

CONCLUSIONThe no-flip method of Shang Ring circumcision was superior to the external method for its advantages of fewer complications, lower incidence of postoperative edema, and mild postoperative pain. However, our findings need further support by more high-quality randomized controlled trials.

BACKGROUND:There are so many studies about ovariectomized rats at present, but the research on the change rules of bone mass, bone turnover markers, estrogen levels and their correlation in different periods of ovariectomized rats is rarely reported. OBJECTIVE:To analyze the change rules of bone mass, bone turnover markers, estrogen level and their correlation in different periods of ovariectomized rats. METHODS: Thirty-four 3-month-old female Sprague Dawley rats were randomly divided into three groups: baseline group, ovariectomized group and sham operated group. At the beginning of the experiment, the rats in the baseline group were sacrificed, then rats in the ovariectomized group and sham operated group were executed at 4, 8, 12 weeks postoperative respectively. The bone mineral density, bone mass content, area of different zones of the L1-3 lumbar vertebrae and femurs were detected by dual-energy X-ray absorption method, and meanwhile the serum levels of type I procolagen amino-terminal pro-peptide, I colagen carboxy-terminal peptide and estrogen were determined by ELISA. At last, we analyzed the correlation between body mass, bone mineral densityin vitro, type I procolagen amino-terminal pro-peptide, I colagen carboxy-terminal peptide and estrogen levels and the age of ovariectomized rats. RESULTS AND CONCLUSION: (1) The bone mineral density and bone mass content of the lumbar vertebral and femurs in the ovariectomized group were significantly lower than those in the sham operated group and baseline group at the 4th week after operation (P < 0.05). The bone mineral density and bone mass content in the ovariectomized group were ameliorated obviously at the 8th and 12th weeks compared with those at the 4th week after operation (P < 0.05). The bone mass loss was highest in the L1 and intertrochanteric regions. (2) Serum levels of type I procolagen amino-terminal pro-peptide and I colagen carboxy-terminal peptide in the ovariectomized group were significantly higher than those in the baseline group and sham operated group at the 4th week after operation, but there was no difference at the 8th and 12th weeks. (3) The serum estrogen level in the ovariectomized group was prominently lower than that in the sham operated group and baseline group at the 8th and 12th weeks after operation (P < 0.01 at the 8th week,P < 0.05 at the 12th week). (4) The age was positively correlated with body mass and bone mineral density of the lumbar vertebrae and femursin vitro, while the serum levels of type I procolagen amino-terminal pro-peptide and I colagen carboxy-terminal peptide were negatively correlated with the bone mineral density of the lumbar vertebrae and femurs in vitro (P < 0.01). These results suggested that the bone mass of the lumbar vertebrae and femurs in ovariectomized rats was decreased rapidly firstly, and then rose slowly with time; the bone mass in the L1 and intertrochanteric regions lost seriously; the bone turnover markers showed a significant increase at the beginning of ovariectomy and reduced gradualy to normal condition, while the estrogen level was increased at the first month after ovariectomy and then decreased rapidly. In addition, the body mass, bone turnover markers and estrogen level were associated with the change of bone mass.

OBJECTIVETo investigate relationship between glucose metabolic disorders and expression of insulin receptor (IR) and tyrosine protein kinase (TPK) in posthepatitic cirrhosis hepatocyte and HBV DNA expression in pancreatic cells.

METHODSTo detect HBV DNA in paraffin-embedded pancreatic and hepatic tissues from 12 posthepatitic cirrhosis patients with positive serum HBV markers by using in situ hybridization (ISH) with a digoxigenin labelled probe. The amount of IR and TPK have been evaluated by immunohistochemical quantitative analysis using image analyzer in hepatocyte of 12 patients positive for HBV markers with posthepatitic cirrhosis in serum. Immunofluorescent histochemical double staining technique was used. HBsAg and IR were observed under confocal laser scanning microscope.

RESULTSEleven of 12 cirrhosis patients? hepatocytes were HBV DNA positive, including 7 patients (7/7) with impaired glucose tolerance (IGT) and 4 patients (4/5) with normal glucose tolerance (NGT). Eight of 12 pancreatic cells were HBV DNA positive, including 7 patients (7/7) with IGT, but only one patient (1/5) with NGT-HBV DNA was found positive in pancreatic cells in significantly more subjects in IGT group than in NGT group (P less than 0.01).IR and TPK amount in hepatocyte of IGT was significantly less than that of NGT patients with posthepatitic cirrhosis (P less than 0.01). IR amount was closely related to the TPK in cirrhosis hepatocyte r=0.82597(P less than 0.01). HBV DNA was mainly localized in the nuclei of hepatocyte and pancreatic acinar and islet cells. Immunofluorescent histochemical double-staining showed that HBsAg was partly localized in the IR positive areas of hepatocytes and pancreatic islet cells.

CONCLUSIONHBV can invade acinar cells of pancreas and islet cells, which might be a direct cause of insulin-dependent diabetes mellitus-like the disorder and insulin absence after HBV infection. Decrease of IR and TPK might be main cause of noninsulin-dependent diabetes mellitus-like disorder after having hepatitis or posthepatitic cirrhosis.

OBJECTIVEDisturbances of the synthesis and breakdown of the extracellular matrix of arterial walls have emerged as key features of the atherosclerotic process. We observed the changes of circulating procollagen marker for type III collagen turnover rate, the N-terminal propeptide P III NP and vascular resistance in hypertensive patients treated with various antihypertensive regimens.

METHODA total of 130 light to moderate hypertensive patients were randomly assigned to receive enalapril (group B, n = 43), enalapril + spirolactone (20 mg/d, group A, n = 44) and anti-hypertensive drugs not directly affecting RAAS (calcium antagonist, beta-blocker, group C, n = 43) for 1 year. Target blood pressure is < 130/80 mm Hg.

RESULTSTarget blood pressure was reached in all treated patients and was similar among various groups. Under the same blood pressure controlling precondition, serum P III NP were similar at baseline among various groups and remained unchanged in group B [(3.4 +/- 0.3) microg/L vs. (3.7 +/- 0.3) microg/L, P > 0.05] and significantly decreased in group A [(2.3 +/- 0.2) microg/L vs. (3.8 +/- 0.2) microg/L, P < 0.05] while significantly increased in group C [(3.9 +/- 2.0) microg/L vs. (3.2 +/- 1.5) microg/L, P < 0.05]. Vascular resistance was similar among groups before therapy and all significantly decreased after 1 year antihypertensive therapy and the decrease was more significant in group A [(1064.3 +/- 158.6) dyn.s(-1).cm(-5)] than that in group B [(1200.8 +/- 298.7) dyn.s(-1).cm(-5)] and group C [(1205.1 +/- 206.4) dyn.s(-1).cm(-5)].

CONCLUSIONSpironolactone in conjunction with enalapril is a more favorable antihypertensive regimen in decreasing P III NP and improving vascular resistance than enalapril alone or antihypertensive drug regimens not directly affecting RAAS.

To investigate the efficacy of interferon alpha 2 b plus ribavirin combination therapy in sixty-two patients with chronic hepatitis c (CHC) infection originating from a single blood donor. The 62 patients who developed CHC following blood transfusion from a known single infected donor were treated with interferon and ribavirin combination therapy for 48 weeks and followed-up for 96 weeks. The therapy regimen consisted of subcutaneous administration of 3-500 MIU interferon alpha 2 b every other day and daily oral administration of 0.6-1.0 g of ribavirin. Patients were monitored during treatment and in follow-up for sustained virological response (SVR), early virology response (EVR), treatment end virology response (ETVR), biochemical response of withdrawals, and side effects. The SVR rate was 83.9% (52/62). The EVR rate was 95.2% (59/62). The ETVR rate was 87.1% (54/62). The biochemical response rate after withdrawal of treatment was 100.0%. Eight patients developed mildly abnormal thyroid function as a result of the interferon therapy, but all were able to complete the antiviral treatment regimen under the care of endocrinologists. Younger age, relatively short course of disease, low viral load, and better compliance, but not sex, were correlated to curative effect of the combination therapy. Interferon alpha 2 b plus ribavirin combination therapy had a significant curative effect on a group of 62 CHC patients originating from a single case, with 52 of the patients showing SVR out to 96 weeks after therapy. Antiviral treatment is recommended for hepatitis C virus-positive patients to eradicate the virus and prevent disease progression.
