Objective:To investigate the hepatitis C virus (HCV) infection in hemodialysis patients.Methods:One hundred and fifty hemodialysis patients were tested for HCV-RNA using a reverse transcription-polymerase chain reaction (RT-PCR) assay and for anti-HCV IgG using an enzyme-linked mmunosorbent assay (ELISA).Result:The positive rate of anti-HCV IgG was 24%.The positive rate of HCV-RNA was 26.7%;the total positive rate of HCV markers was 35.3%.Conclusion:HCV infection rate in hemodialysis patients is higher than that of general population.The first-class risk factors for HCV infection is transfusion of blood,while the cross using of dialyzer and dialysis pipe-line is also one of the risk factors.

Objective To compare the effects of different doses of dexmedetomidine on the median effective concentration (EC50) of ropivacaine for epidural block and investigate the appropriate dose.Methods One hundred and twenty ASA Ⅰ patients of both sexes,aged 20-55 yr,weighing 50-75 kg,scheduled for knee arthroscopic operation,were randomly divided into 4 groups (n =30 each):no dexmedetomidine group (group D0),0.25 μg/kg dexmedetomidine group (group D0.25),0.50μg/kg dexmedetomidine group (group D0.50),and 1.00μg/kg dexmedetomidine group (group D1.00).In group D0,ropivacaine 20 ml was injected into epidural space.The ropivacaine-dexmedetomidine mixtures containing 0.25,0.50 and 1.00 μg/kg dexmedetomidine were injected into epidural space in groups D0.25,D1.00 and D0.50 respectively.The volume of mixtures was 20 nl in groups D0.25,D1.00 and D0.50.The initial concentration of ropivacaine was set at 0.40 ％,0.40 ％,0.28 ％ and 0.20 ％ in groups D0,D0.25,D0.50 and D1.00 respectively and then the EC50 was determined by up-and-down technique.The concentration of ropivacaine was increased/decreased by 0.02％ in the next patient.The analgesic effect was assessed using VAS score.VAS score =0 was considered as effective analgesia.The EC50 and 95％ confidence interval (CI) of ropivacaine were calculated using probit method.Adverse effects were recorded.Results The EC50 and 95 ％ CI of ropivacaine was 0.38％ (0.35-0.41)％,0.34％ (0.31-0.36)％,0.22％ (0.20-0.24)％ and 0.14％ (0.12-0.15) ％ in groups D0,D0.25,D0.50 and D1.00 respectively.The EC50 of ropivacaine was decreased gradually in groups D0,D0.25,D0.50 and D1.00 ( P ＜ 0.05).Compared with group D0,the incidonce of hypotension and bradycardia was significantly increased in group D1.00 ( P ＜ 0.05),while no significant change was found in the incidence of adverse effects in groups D0.25 and D0.50 (P ＞ 0.05).Conclusion The appropriate dose of dexmedetomidine for epidural analgesia is 0.50 μg/kg.

Objective In order to provide the basis for establishment of food allergy models , we compared the differences of sensitivity and alterations of intestinal flora of food allergy models in two strains of mice .Methods Forty 4-5-week old female BALB/c and Kunmimg mice were divided into control group ( n=10) and food allergy goup ( n=30), respectively.Ovalbumin (OVA) was injected to the mice to establish food allergy models .Serum OVA-specific IgE of the mice was assayed by ELISA .The jejunum tissue was examined by pathology with HE staining .The changes of fecal flora were detected by denaturing gradient gel electrophoresis (DGGE).Results (1)Among the sensitized 60 mice, OVA-sIgE levels were significantly increased in 27/30 BALB/c mice and 21/30 KM mice compared with those of control groups(P<0.001).Moreover, there were more evident inflammatory cell infiltration , epithelial cell shedding and cytolysis in the jejunal villi of BALB/c mice than those of KM mice.(2) After food allergy modeling, there were significant changes of intestinal flora in the BALB/c mice (P<0.001), while only significant change of evenness was found in the KM mice (P<0.05).(3)There were changes of abundance , Shannon index and evenness of intestinal flora in the model groups of BALB/c and KM mice.Conclusions BALB/c mice are more sensitive to OVA allergy than KM mice .The composition of intestinal flora is different among different strains of mice .The changes of intestinal flora after OVA challenge in BALB /c mice are more obvious than those in KM mice .

This study was aimed to observe the influence ofQing-Chang Hua-Shi Recipe (QHR) on IL-6trans-signaling in experimental colitis mice, in order to initially explore the possible mechanisms of QHR for ulcerative colitis (UC). TNBS/ethanol was used in the establishment of colitis mice model. After intervention of medication, ELISA was used in the detection of soluble Interleukin-6 receptor (sIL-6R). Real-time PCR was used to detect the mRNA expression level of IL-6 and glycoprotein 130 (gp130). Western blot was used in the observation of protein expression of IL-6 and gp130 in the colonic mucosa. The results showed that the level of sIL-6R, the mRNA and protein expression of IL-6 and gp130 in the model group were significantly higher than that in the control group. QHR was able to reduce the sIL-6R level (P < 0.01), decreased the mRNA and protein expression of IL-6 and gp130 (P < 0.01) in the colon tissues among experimental colitis mice. It was concluded that QHR had good anti-inflammatory effects on experimental colitis mice. It might be associated with influencing IL-6trans-signaling.

Objective To evaluate the effect of isoflurane or sevoflurane inhalation before and after gestation on the offspring brain development. Methods Thirty female adult Sprague Dawley rats were randomly assigned into 5 groups(n=6 each):control group(group C),group that ex?posed to isoflurane with the concentration of 1.6%for 6 hours before gestation(group BI),group that exposed to isoflurane with the concentration of 1.6%at the 6th,10th,14th and 18th day for 6 hours(group PI),group that exposed to sevoflurane with the concentration of 2.4%for 6 hours before gestation(group BS),and group exposed to sevoflurane with the concentration of 2.4%at the 6th,10th,14th and 18th day for 6 hours after gestation (group PS). Twelve offspring rats from pregnant rats in each group were chosen on the day of birth(T1),and 7th,14th and 28th days after birth(T2, T3 and T4)and sacrificed,and the hippocampi were then isolated. Hematoxylin and eosin stain were adopted to observe the tissue pathological change. Electron microscope was used to observe the neuron ultrastructure change of hippocampus. Immolunohistochemistry was used to detect cas?pase?3,the expression of growth associated protein?43(GAP?43)and neuronal nitric oxide synthase(nNOS). Results Compared with group C, no significant change was found in caspase?3,GAP?43 and nNOS expression in offspring rat hippocampus in groups BI and BS(P>0.05),and no damage change in hippocampal was seen by HE staining and electron microscopy. In group PI and PB,the expression of caspase?3 was significantly up?regulated,the expression of GAP?43 and nNOS was down?regulated at T1 to T3(P<0.01),and structural changes in cell were seen by electron microscopy. In group PI,significant pathological changes in hippocampal were seen by HE staining at T1 to T3. Compared with group PI,the expres?sion of GAP?43 and nNOS was significantly up?regulated(P<0.01),and the expression of caspase?3 was down?regulated at T1 to T3(P<0.01). Conclusion Isoflurane or sevoflurane inhalation before gestation does not affect the offspring brain development,while isoflurane or sevoflurane in?halation after gestation can induce transient abnormal change of offspring brain development,and isoflurane′s toxicity was greater than sevoflurane.

Objective To discuss the value of high resolution MRI in the evaluation of small intralabyrinthine lesions with the symptom of vertigo. Methods We retrospectively analyzed the imaging examination techniques and imaging finding of 13 cases of labyrinthine hemorrhage or exudate and 6 cases of intralabyrinthine schwannoma (ILS) with the symptom of vertigo. Two cases of labyrinthine hemorrhage or exudate and 3 cases of ILS underwent temporal bone high resolution CT(HRCT) scan and all the 19 patients received highresolution MR examination. Patients of labyrinthine hemorrhage or exudate received fluid?attenuated inversion recovery (FLAIR)T2WI in addition to routine pre?contrast temporal bone MR. Pre?and post?contrast MR of the temporal bone were performed on the ILS patients. In particular, 3 ILS cases received three?dimensional sampling perfection with application?optimized contrasts by using different flip angle evolutions (3D?SPACE) sequence. Results There was no abnormal finding on HRCT of the inner ear of the 2 labyrinthine hemorrhage cases. On T1WI, regions of mild increased signal intensity of the labyrinth of affected side could be spotted in 7 patients whereas no abnormal signal intensity was found in the other 6 patients. On T2WI, all the 13 labyrinthine hemorrhage or exudate cases had no abnormal finding in the inner ear. On FLAIR T2WI sequence, regions of increased signal intensity of the labyrinth of affected side could be found in all the 13 cases. Thress ILS patients that received HRCT scan showed no valuable finding. On T1WI, no abnormal signal intensity was found in the labyrinth of the 6 patients. On T2WI, regions of decreased signal intensity of the labyrinth could be found in only 3 patients. All the 3 cases that received 3D?SPACE sequence appeared as a filling defect in the high?signal labyrinth clearly while 2 of the 3 lesions could not be found on T2WI. After Gadolinium administration, all the 6 ILSs were obviously enhancing. Conclusions High resolution MRI is valuable in the diagnosis of labyrinthine hemorrhage or exudate and ILS. The use of FLAIR T2WI sequence can help us to find labyrinthine hemorrhage or exudate more sensitively. The use of 3D?SPACE sequence can help us to detect and diagnose small intralabyrinthine lesions.

Objective To explore the diagnosis, treatment and prognosis of acute perforation of gnstric cancer. Methods The clinical data of 24 patients with acute perforation of gastric cancer who had been admitted to Guangzhou General Hospital of PLA from July 1996 to December 2008 were retrospectively analyzed. Results Of all patients, 4 were treated by perforation repair, 2 by perforation repair combined with gastrojejunostomy, 11 by palliative subtotal gastrectomy, 2 by radical gastrectomy, and 5 by radical gastrectomy after perforation repair. The mean survival time of patients treated by perforation repair, perforation repair combined with gastro-jejunostomy, partial gastrectomy and radical gastrectomy were (4±5), (6±9), (12±7), and (25±9) months, respectively. Conclusions Early diagnosis and reasonable operation are the keys to decrease the morality and increase life quality for patients who suffered from acute perforation of gastric cancer. Different pathologic stages maybe an important factor in deciding the prognosis.

Objective To discuss the relationship between serum 25-hydroxy vitamin D[25(OH)D] level and the severity of diabetic retinopathy in type 2 diabetes mellitus.Methods 1474 cases of type 2 diabetic patients were classified into three groups according to their severity of diabetic retinopathy, the non-diabetic retinopathy group(NDR group, n =640), the background diabetic retinopathy group(BDR group, n =494) and the proliferative diabetic retinopathy group(PDR group, n=340).640 healthy people with normal level of glycosylated hemoglobin(HbA1c) were selected as control group(NDM group, n=640).Disease duration, body mass index(BMI), systolic pressure, low density lipoprotein-cholesterol(LDL-C), HbA1c and 25(OH)D were detected and compared among groups.Results Disease duration and HbA1c were increasing significantly, and the levels were NDM groupNDR group>BDR group>PDR group(all P<0.05).The level of 25(OH)D was negatively related to disease duration and HbA1c (P<0.001), and it was negatively associated to the severity of diabetic retinopathy(r=-0.855,P<0.001).Conclusion The decrease of 25(OH)D level is closely associated with the severity of diabetic retinopathy in patients with type 2 diabetes mellitus, and it might be an important predictor for the severity of diabetic retinopathy.
