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.

AIM: To investigate chemical constituents of Spatholobus suberectus Dunn. METHODS: Isolation and purification were carried out by column chromatographic methods. Compounds were characterized based on their physical characteristics and spectra data. RESULTS: Seventeen compounds were isolated from ethanol extract of S. suberectus. The structures were elucidated as prestegane B (1), (2R, 3R)-buteaspermanol (2), (+)-medioresinol (3), (2R, 3R)-3,7-dihydroxyflavanone (4), benzeneethanol (5), 4, 7, 2'-trihydroxy-4'-methoxyisoflavanol (6), naringenin (7), blumenol A (8), protocatechuic acid ethyl ester (9), liquiritigenin (10), 7, 4'-dihydroxy-8-methoxy-isoflavone (11), 3, 5, 7, 3', 5'-pentahydroxyflavanone (12), protocatechuic acid (13), glycyroside (14), 8-methylretusin-7-O-β-D-glucopyranoside (15), 3, 3', 4', 5, 6, 7, 8-heptahydroxyflavan (16), and dulcisflavan (17). CONCLUSION All compounds are firstly isolated from the title plant and compounds 1, 3 were isolated from the Spatholobus genus for the first time.

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.

Chylothorax is a rare complication of neck dissection, and bilateral chylothorax is even rarer. However, both are potentially serious and sometimes life-threatening, especially those that are associated with left neck dissection for head and neck neoplasms. We report one case of bilateral chylothorax following left supraclavicular dissection for breast cancer. This case was treated successfully with a new conservative management approach.

OBJECTIVETo study the association of TGF-alpha gene polymorphism and non-syndromic cleft lip with cleft palate in Shandong province.

METHODSPolymerase chain reaction combined with restrict enzyme digestion was used to detect the target gene variation in 98 patients with non-syndromic cleft lip with cleft palate and 101 healthy controls.

RESULTSThe C2 allele frequency in patients with non-syndromic cleft lip with cleft palate was significantly higher than that in healthy controls. The genotype frequency in patients with positive family history was significantly higher than that without positive family history.

CONCLUSIONTGF-alpha gene polymorphism is closely associated with non-syndromic cleft lip with cleft palate in Shandong, especially in patients with positive family history.

This paper reports the surface morphology and I-V curves of porous silicon (PS) samples and related devices. The observed fabrics on the PS surface were found to affect the electrical property of PS devices. When the devices were operated under different external bias (10 V or 3 V) for 10 min, their observed obvious differences in electrical properties may be due to the different control mechanisms in the Al/PS interface and PS matrix morphology.

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.
