Objective To establish a method to determine 7 kinds of volatile halohydrocarbons in drinking water with headspace gas chromatography. Methods The water samples were heated by water bath,the water head space gas was injected into gas chromatography,separated by DB-624 capillary column and then detected by ECD detector. Results Under the optimal experimental conditions,the methods had a wide linear range,the lowest determination limits was 0.001-0.05 ?g/L,the relative standard deviation was 3.6%-8.9%,the rate of recovery was 84%-104%,the linear range of determination was 0.01-50 ?g/L. Conclusion This method is sensitive,simple,accuracy and is appllicable for determination of 7 kinds of volatile halohydrocarbons in drinking water.

Objective To observe the effects of salmeterol/fluticasone on the bone metabolism and bone density of the patients with moderate COPD and whether the effects is relate with inhaled corticosteroid course. Methods Sixty pa-tients with COPD were divided into 2 groups by random digit table. Patients in experimental group (n=30) were given conven-tional therapy with salmeterol/fluticasone one inhale(bid) for continuously 12 months while patients in control group (N=30) were given conventional therapy without any glucocorticoid.The bone mineral density (BMD) of the femoral triangle in all patients were measured by DXA before therapy, 3 months and 12 months after therapy. At the same time, biochemical indi-cators that are correlated with bone metabolism include bone gla protein (BGP) and alkaline phosphatase (ALP) were mea-sured by radioimmunoassay. Results The BMD, BGP and ALP of patients in experimental group and in control group be-fore therapy, 3 month and 12 month after therapy were compared. There is no significant difference (P>0.05) between these two groups before therapy and after 3 month but significant difference was shown after 9 months (P<0.05). Conclusion Short period inhaling salmeterol/fluticasone in patients with COPD is safe. But long-term inhaling salmeterol/fluticason may lead to decline of the bone density in patients with COPD.

Objective:To investigate the expression of u-PA and PAI-1 and their possible role in oral submucous fibrosis(OSF). Methods:Immunohistochemistry and imaging analysis were used to detect the expression of u-PA and PAI-1 in 30 cases of OSF and 10 cases of normal control.Results:The expression of u-PA and PAI-1 was observed in the cytoplasm of blood vessel endothelium,fibroblasts and inflammatory infiltration cells in lamina propria of OSF and control samples.u-PA expression was increased at the early stage of OSF(P0.05).PAI-1 expression was increased following the development of the disease(P

Objectives To investigate the clinical features of Guillain-Barré syndrome (GBS) in children from Shen-zhen. Methods The clinical manifestations, results of electrophysiological tests and prognosis of 28 GBS patients from July 2002 to July 2012 were retrospectively analysed. Results Of 28 children, 16(57.1%) had preceding acute upper respiratory infection for 3-14 days but no patient had acute gastroenteritis. One had received HBV vaccination in 2 weeks before the onset of GBS. The peak season for GBS is spring. According to the clinical presentations and the neurophysiological results 17 patients had demyelinating neuropathy, 5 acute motor axonal neuropathy, 2 acute motor sensory axonal neuropathy, 3 Miller-fisher syndrome, and 1 polyneuritis cranialis. 14 (50.0%) patients suffered from pain in limbs which is the most nota-ble symptom in the early stage. Intravenous immune globulin (IVIG) and steroids were given during the acute phases in the majority of the patients, and assisted ventilation was performed in 2 patients due to respiratory muscle paralysis. No diffe-rence was found in Hughes scores, average hospitalization durations, and the prognosis between patients with GBS variants patients and patients with classic GBS. Conclusions Children with GBS in Shenzhen area have different clinical features.

Objective To explore the relevance between lipoprotein(a) and atherosclerotic renal artery stenosis in adults.Methods Literature search was conducted in PubMed and EMBASE Database,using “atherosclerotic renal artery stenosis” as the search term as well as in Wanfang Database,China National Knowledge Infrastructure,and Cqvip Database,using “renal artery stenosis” and “lipoprotein” as the search terms,aiming to find case-control or cohort studies published before 2010.The qualities of all the literatures enrolled were evaluated using Newcastle-Ottawa scale and the data from which were analyzed by the Review Manager 5.0 software.Results Five eligible case-control studies (661 cases) entered the Meta analysis.The results showed that the lipoprotein(a) level was not significantly higher in the case group than that in the control group [ mean difference =0.0702 g/L,95％ CI ( - 0.0688,0.2092),P =0.32 ].Conclusion According to the existing studies,the relevance between lipoprotein(a) and atherosclerotic renal artery stenosis can not be established.

Objective To investigate the effects of ulinastatin on pulmonary and hepatorenal function of elderly patients undergoing resection of esophageal cancer. Methods The clinical data of 40 elderly patients with esophageal cancer who had been admitted to Southwest Hospital from January 2005 to January 2008 were retrospectively analyzed. All the patients were randomly divided into control group (n = 20) and ulinastatin group (n = 20) according to random number table. Patients were administered with total parenteral nutrition, and patients in ulinaslatin group were additionally instilled with 4×10~5 U/d of ulinastatin. The levels of PaO_2, PaCO_2, PaO_2/FiO_2, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (Tbil), blood urea nitrogen, creatinine and uric acid were detected preoperatively and at postoperative day 2 and day 6. All the data were analyzed by t-test and chi-square test. Results The levels of PaO_2 and PaO_2/FiO_2 were (87.3±4.2) mm Hg (1 mm Hg =0.133 kPa) and (416±20)mm Hg in ulinastatin group, which were significantly higher than (79.0±4.3)mm Hg and (376±20)mm Hg in control group (t =6.2, 6.2, P <0.05). The levels of ALT, AST and Tbil were (23±7)U/L, (38±8)U/L and (13.4±3.0) μmol/L in ulinastatin group, and (39±8) U/L, (50±9) U/L and (24.5±6.0) μmol/L in control group, with significant difference between the 2 groups (t = 7.0, 4.4, 7.6, P < 0.05). The levels of uric acid, blood urea nitrogen and creatinine were (279±84) μmol/L, (4.1±1.7) mmol/L and (66±12) μmol/L in ulinastatin group, and (386±67)μmol/L, ( 8.9±2.7) mmol/L and (95±38) μmol/L in control group, with significant difference between the 2 groups (t = 4.4, 6.4, 3.3, P < 0.05). The recurrence of complications in ulinastatin group was significantly lower than that in control group (χ~2 = 4.8, P <0.05). Conclusion Postoperative supplementation of ulinastatin and total parenteral nutrition is helpful in improving the pulmonary and hepatorenal function of elderly patients undergoing resection of esophageal cancer.

Purpose To observe the action time of parthenolide (PTN) as selective nuclear factor-κB(NF-κB) inhibitor in heart of rats.Methods Forty SD rats were randomly divided into control(CON) group,PTN group,dimethyl sulfoxide(DMSO) group,lipopolysaccharide(LPS) group and PTN+LPS group.The first day:PTN group,DMSO group and PTN+LPS group rats were respectively injected interapertoneally PTN(500 μg/kg) and DMSO; other groups rats were injected interapertoneally equivalent saline.The second day(in equivalent to 24 h after injecting PTN):in LPS group and PTN+LPS group LPS(12.5 mg/kg) was administered subcutaneously; other group rats were injected subcutaneously equivalent saline.Every heart was obtained in equivalentce to 1 h after injecting LPS to measure the expression of NF-κB p50 in nucleus,inhibitory kappaB(IκBα) and phosphorylation inhibitory kappaB(p-IκBα) in cytoplasm of cardiac myocytes through Western blotting.Results Compared with CON group,the expression of NF-κB p50,IκBα and p-IκBα had no difference in PTN and DMSO group.And in LPS group and PTN + LPS group,the expression of NF-κB p50 up-regulated significantly(P＜0.05),IκBα down-regulated(P＜0.05) and p-IκBα up-regulated significantly(P＜0.05).Conclusion LPS can activate NF-κB in 1 h and PTN in rats after 24 h has few effect.
