Methods:The mice were fed with soybean phospholipids of 2 . 5, 5 . 0 , 10.0 g/kg bw respectively while control group with distilled water for 30 days. Then the mice were killed and contents of fatty acids and phospholipids in erythrocyte membranes were detected by HPLC. Results: (1)The contents of linoleic acid (C18 ∶2) and linolenic acid ( C18 ∶3), the composition of polyunsaturated fatty acid (PUFA) were increased obviously (P

Objective:To investigate the clinical manifestations and causative factors of adverse drug reactions following cinepazide mahate injection and provide reference for the safe use of drugs.Method:503 cases treated with cine- pazide maleate in our hospital were retrospectively studied and the results were statistically analyzed by SPSS(versionl 1.0).Result:Of 503 patients,27 cases presented some adverse events with an incidence of 5.4%,and adverse drug reac- tions were found in 11 cases with an incidence of 2.2%.The main adverse drug reactions were nervous,gastrointestinal and dermal reactions.The adverse drug reactions had no relation with sex,but with age of patients and combination use of drugs(P

Objective To investigate the dynamic changes of MDA, NO, SOD and pathologic changes of the lung and kidneyduring repefusion after haemorrhagic shock in rabbits, and to study the protective effects of edaravone during thecourse.Method Totally 29 beparinized (3 mg/kg) rabbits were randomly divided into three groups:tho sham-operatedcontrol group (group C, n = 7), the haemorrhagic shock group (group I/R, n = 10), and the haemorrhagicshock group with edaravone infusion (group I/R-edaravone, n = 12). Rabbits in the latter two groups were bledfrom left arteria cmralis in 10 minutes with MAP maintained at 40 mmHg for 60 minutes, and then group I/R-edar-avone was given edaravone intravenously. After that, resuscitation began:all blood loss was replaced with normalsaline within 60 minutes with MAP at the end ≥ 70% MAP before haemorrhagic shock. Edaravone was reinjectedat 10 hours after shock.All rabbits were killed at 20 h after reperfusion.Plasma nitric oxide(NO), malonyldialde-hyde (MDA) and superoxide dismutase(SOD) in every group were measured before shock,60 minutes after shockaad 1 h, 5 h and 20 h after reperfusien. Part of the right lung and the right kidney tissues were taken from everyrabbit for pathologic examnation after sacrifice.Results There was no significant difference in MDA,NO aad SOD among three groups before shock. A higherlevel of MDA (5.35±0.29 μmol/L), NO(27.75 ±2.88 μmol/L)and lower serum concentration of SOD(194.58±14.42U/ml)could be found in group I/R during haemorrhagic shock,as compared to group C(4.44±0.59 μmol/L,25.01±4.95μmol/L,210.86±24.54U/ml,respectively,P<0.01).At 20 hours after resuscitation,MDA and NO contents continued to increase(5.69±0.24 μmol/L and 28.01±3.10 μmol/L respectively,P<0.05)while SOD contents kept decreasing(151.83±9.36 U/ml,P<0.05)in group I/R.Comparing to group I/R,group I/R-edaravone had significant lower level of MDA(3.48±0.23 μmol/L,P<0.01)and higher concentration of SOD(195.10±11.87U/ml,P<0.01).Edaravone attenuated the pathologic changes in the lung and kidney.Conclusions Edaravone could effectively protect vital organs from reperfusion injury caused by free radicals following haemorrhagic shock by reducing plasma levels of MDA,NO and increasing levels of SOD.

Objective To investigate the incidence and risk factors of surgical site infection(SSI)in neurosurgical patients in a tertiary first-class hospital,and provide reference for the prevention and control of SSI.Methods 47 neurological patients with SSI (49 patients developed SSI,2 were excluded from study due to the lack of appropriate control subject)from December 31 ,2011 to December 31 ,2012 were as infected group,and 94 patients without SSI (1 ∶2 matching)were as non-infected group,risk factors for SSI were analyzed retrospectively.Results There was no significant difference in general condition of two groups of patients (all P >0.05 );among 3 708 patients,49 (1 .32%)developed SSI;intracranial infection was the main type of SSI (89.80%);27 patients were performed ce-rebrospinal fluid (CSF)bacteriological detection,6 (22.22%)of whom were positive for CSF bacteriological detec-tion.Univariate conditional logistic regression analysis showed that risk factors for SSI in neurosurgical patients were operational risk assessment score (OR =2.04),frequency of preoperative antimicrobial use(OR =3.15 ),fre-quency of intraoperative antimicrobial use(OR=2.58),duration of operation(OR=2.70),surgical blood loss(OR=1 .72),indwelling drainage tube(OR=4.30),duration of indwelling drainage tube after operation(OR=2.06),and time for initial dressing change(OR=1 .66);Multivariate conditional logistic regression analysis showed that the in-dependent risk factors for SSI were frequency of preoperative antimicrobial use(P =0.03,OR =4.86),duration of operation(P =0.05,OR = 2.89 ),and time for initial dressing change after operation (P = 0.01 ,OR = 1 .92 ). Conclusion Risk factors for SSI in department of neurosurgery are multiple,duration of operation,duration of in-dwelling drainage tube after operation,and time for initial dressing change after operation are major risk factors.

AIM: To study the possibility that yellow wine improves the pathological changes of atherosclerosis in vivo. METHODS: Six weeks old LDL receptor knockout mice (n=48) on a high-fat and L-methionine diet developed plasma hyperhomocysteinemia and atherosclerosis. The animals were randomly divided into yellow wine group, red wine group, ethanol group and control group (n=12 in each group) and were sacrificed after 14 weeks. The levels of plasma lipids and homocysteine in serum were examined. The morphological changes of aorta artery and the atherosclerosis of aorta sinus were observed under microscope. The expression and activation of matrix metalloproteinase-2 (MMP-2) were determined by the method of immunohistochemistry. RESULTS: No significant difference of plasma total cholesterol, triglyceride or high density lipoprotein cholesterol among groups was observed. Plasma homocysteine was significantly decreased in yellow wine group as compared to other three groups (P<0.01). Compared to ethanol and control groups, use of yellow wine and red wine significantly reduced the atherosclerosis lesion area (P<0.01). However, no significant discrepancy between the yellow wine group and red wine group was found. Compared to control group, the expression of MMP-2 in yellow wine group, red wine group and ethanol group decreased by 26.3%, 27.6% (P<0.01) and 5.7% (P>0.05), respectively. The activity of MMP-2 in yellow wine group, red wine group and ethanol group decreased by 31.7%, 32.5% (P<0.01) and 6.7% (P>0.05), respectively. CONCLUSION: Yellow wine and red wine inhibit the expression of MMP-2 and improve the pathologic changes of atherosclerosis, indicating that they have benefic effects on cardiovascular system.

Background and purpose:HPV infection is known as the primary cause of cervical cancer worldwide To investigate high risk type human papillomavirus (HPV) prevalence and incidence rates of cervical intraepithelial neoplasia (CIN) and their screen risk factors in women with different methods of screening.Methods:1137 residents, workers and service women aged 15-59 from Shenzhen city were investigated for cervical cancer in an epidemiology screening study.The high risk types of human papillomavirus of liquid-based cytology samples were tested by hybrid capture 2 (HC-Ⅱ) and liquid-based cytology test (LCT) was also performed at the same time. Women for HPV-positive with LCT ≥ atypical squamous cells of undetermined sign (ASCUS) or HPV-negative with LCT ≥ low grade squamous intraepithelial lesion (LSIL) were biopsied in colposcopy and then were examined by pathology. All data was managed by Foxbase. ?2 test and unconditional Logistic regression model were used for data analysis by SPSS 10.0.Results:1137 women were eligible in our research, the overall rates of HPV infection was 14.0%. HPV detection rates in residents, workers and service women were 14.1%,9.2%,18.9% respectively. HPV detection rates in workers group was significantly lower than that of service women and residents (P

OBJECTIVETo assess the accuracy of immunological fecal occult blood test (iFOBT) for detection of colorectal cancer (CRC).

METHODSA total of 1 197 studies published before June 2014 were selected from PubMed and Embase and 17 of which were finally included in this meta-analysis. A bivariate mixed-effects models was used for overall value merging and heterogeneity testing. In addition to the overall sensitivity and specificity, the analyses were also performed among certain subgroups, including a "colonoscopy group" (all were referred for colonoscopy diagnosis regardless screening results) and a "follow-up group" (only the screening positive were referred and all were then followed up), a qualitative group and a quantitative group (classified by the way of iFOBT result reading).

RESULTSA total of 161 502 subjects aged from 48 to 63 years were included in the analysis. IFOBT had an overall integrated sensitivity of 0.85 (95% CI: 0.79-0.89) (heterogeneity test: Q = 59.67, P < 0.001) and an overall integrated specificity of 0.93 (95% CI: 0.92-0.94) (heterogeneity test: Q = 1 722.53, P < 0.001) for detection of CRC. In the subgroup analysis, it was found that in the "colonoscopy group" and in the "follow-up group", the sensitivity were 0.81 (95%CI: 0.73-0.87) and 0.88 (95% CI: 0.81-0.92), respectively; the specificity were 0.92 (95% CI: 0.89-0.93) and 0.95 (95% CI: 0.94-0.96), respectively. It was also found that in the qualitative group and the quantitative group, the sensitivity were 0.84 (95% CI: 0.76-0.90) and 0.86 (95% CI: 0.78-0.92), respectively; the specificity were 0.94 (95% CI: 0.91-0.96) and 0.93 (95% CI: 0.91-0.94), respectively.

CONCLUSIONIFOBT had high overall sensitivity and specificity for detecting colorectal cancer.

Disability-adjusted life years (DALYs) has been increasingly used to estimate burden of disease worldwide. By giving a particular attention to DALYs, the objectives of the study were to review various data sources and to conduct an extended estimation on the burden of cancer in China. Based on the publications released by the GLOBOCAN 2008 program and the Global Burden of Disease 2010 (GBD 2010) program, we reviewed the methodological information and gathered DALY data associated with burden of cancer in China, and then we extracted and summarized the data and conducted an extended analysis. From a methodological perspective, both of the programs applied the utility weights mainly from populations other than China. The data from GLOBOCAN 2008 suggests that liver cancer has replaced lung cancer and became the leading cancer in males in China when using DALY rather than mortality rate as the indicator (6.3 million and 5.4 million DALYs, respectively); although the ranking is different, data from the GBD 2010 project shows DALYs caused by liver cancer is comparable to that associated with lung cancer (7.9 million and 8.0 million, respectively). The years lived with disability (YLDs) comprised 26% and 12% of the total DALYs associated with breast cancer and colorectal cancer in China. Both projects suggest that liver cancer might have become or is becoming the leading contributor to males' DALYs in China. There are indications that, along with economic development, YLD will play a more important role in estimation of burden of cancer in China; it suggests that China should consider introducing DALY into the estimation system as early as possible. It also suggests that research on quality of life and utility associated with the major cancers in China need to be systematically conducted to facilitate more accurate DALY estimation.
