Objective To investigate the percentage of CD4 + C125 +Tregs in peripheral blood of patients with sepsis and its effect on cell immunity so as to unravel the effect of immunomodulatory therapy on it. Method Fourty patients with sepsis in ICU were randomly (random number) divided into experimental group and control group . The patients of experimental group were treated with Ulinastatin and immunoregulation agent (Thymosin αl) as well. The blood specimens were collected just before treatment, 3 days and 8 days after treatment. The percentages of CD4 + CD25 + Tregs and lymphocyte subsets were detected by using FCM (flow cytometry), and TNF-α, IL-6 and IL-10 assayed by using ELISA, and APACHE Ⅱ scores were calculated. Results Before treatment, the percentage of CD4 + CD25 + Tregs increased, and the number of lymphocytes and the percentage of T lymphocytes decreased, especially the CD4 + T lymphocytes and CD4+/CD8+ decreased more markedly, and the levels of IL-6 and TNF-α increased. After treatment,the percentage of CD4+ CD25 + Tregs was decreased, the number of lymphocytes and CD4 +/CD8 + increased, and the levels of APACHE Ⅱ score, IL-6 and TNF-α decreased especially in the experimental group decreased more significantly (P ＜ 0. 05). Conclusions The percentage of CD4 + CD25+ Tregs in peripheral blood can reflect the immune status of patients with sepsis and become a novel indicator to estimate the progress of sepsis, and the immunity and prognosis of patients. Treating the patients with Thymosin αl and Ulinastatin can raise their immunity, decrease the levels of IL-6, TNF-α and APACHE Ⅱ score and improve their prognosis.

Objective To study the relationship between serum uric acid and insulin resistance in type 2 diabetic patients Methods A total of 728 middle-aged and elderly type 2 diabetic patients were recruited and the anthropometric,clinical and biochemical parameters and fasting serum C-peptide were measured and retrospectively studied.All patients were divided into groups based on the levels of uric acid and on metabolic syndrome diagnosis or not.Results Among a total of 728 patients,the proportion of hyperuricemia was 26.9％(196/728),and metabolic syndrome(MS)was 64.6％.The levels of body mass index(BMI),waist circumference(WC),systolic pressure (SBP),diastolic pressure (DBP),triglyceride (TG),fasting C-peptide,HOMA(C-Peptide) were significantly higher in hyperuricemia group than in normal uric acid group,while the level of HDL was lower in hyperuricemia group than in normal uric acid group.The proportion of MS was statistically higher in hyperuricemia group (81.6％)than in normal uric acid group (58.3％,P ＜ 0.05).Groups Ⅰ,Ⅱ,Ⅲ,Ⅳ-the four quartiles of serum uric acid from low-to high-level were correlated with MS component number of 2.1±1.0,3.1±1.1,3.3±1.2,3.7±0.8,separately,and with HOMA(CP)of 3.7± 0.8,3.7 ± 0.8,4.0 ± 0.6,4.1 ± 0.9,separately (all P ＜ 0.05).When all patients were divided into groups based on with or without MS,the level of uric acid in MS group was (377.3 ± 43.5)μumol/L,and the proportion of hyperuricemia was 34.0％ (160/470),and HOMA(CP)was 3.90±0.72,all were significantly higher than those of non-MS group[(318.2±47.9)μmol/L,14.0％ (36/258),3.64±0.67].The levels of serum uric acid in groups with 1-5 components of MS were(285.0±62.8)μmol/L,(335.7±62.7)μmol/L,(367.1±45.0) μmol/L,(377.9±40.2) μmol/L,(389.8±46.6)μmol/L,and HOMA(CP) was 3.6±0.6,3.7±0.7,3.9±0.8,3.9±0.7,4.3±0.7 separately(P＜0.05).Serum uric acid was positively correlated with age,WC,BMI,TG,SBP,fasting C-peptide,and HOMA (CP),while negatively correlated with glycosylated hemoglobin(HbA1C),high density lipoprotein cholesterol (HDL-C).Binary logistic regression showed that the OR value of MS was 1.033 with the increase of serum uric acid,and 95％CI:1.026-1.041,P＜0.05.Conclusions Serum uric acid is correlated with insulin resistance in middle-aged and elderly hospitalized patients with type 2 diabetes.Hyperuricemia might be a new risk factor for MS.

Strong inhibition of Bacillus subtilis strain NJ-18 on mycelia growth of Alternaria solani was observed in the antagonistic tests by cylinder plate methods, and the inhibition width was 21.5 mm. Observation under microscope found that the supernatant of fermentation from NJ-18 could make the pathogen hyphae cells malformed and swelled, and consequently the growth of the pathogen was inhibited. Determining of the colonization in potato plants by the signed rifampicin-resistance in NJ-18 showed that it could colonize well in the plants, the colonization quantity of NJ-18 in the root and stem of the potato detected 30 days after fermentation irrigation was 103 CFU/g plant’s fresh weight. In pot experiment, we inoculated the tomato plants with the spore suspensions of Alternaria solani after spraying the fermentation of NJ-18, the results were investigated in 14 days and the efficacy in controlling the disease was 72.9%, which was significantly higher than 45.7%, the efficacy resulted from spray treatment of 2000 fold dilution of 50% iprodione wetable powder.

OBJECTIVETo explore the strategy of pediatric intractable epilepsy surgery.

METHODSThe clinical data of 96 pediatric cases with intractable epilepsy and epilepsy syndromes underwent surgical treatment from April 2004 to April 2006 were retrospectively analyzed.

RESULTSThe surgical treatments were performed based on the results of comprehensive data from neurological, neurosurgical and pediatric departments. Among of them, 78 cases were performed with curative procedure, 17 cases with palliative procedure and 1 case with stereotactic damage procedure. The surgical effect was judged with Engel's standard, 58 cases had no seizure during 14 to 26 months follow-up, 26 cases had significantly improved in seizure control and the total efficiency was 87.5%. 81 cases had improvements in neuropsychological tests. 22 cases had postoperative complications such as neuro-dysfunctions and 15 cases were gradually recovered after the period of follow-up ended, 1 case died of CSF over drainage after operation 3 months.

CONCLUSIONSPediatric patients with symptomatic epilepsy and epilepsy syndromes are suitable to surgical treatment, the results are satisfactory in seizure control and neuropsychological function tests.

Objective To study the expression of MCP-1 and its correlation with SSc.Methods Twenty-seven patients with SSe and 21 healthy control subjects were examined for MCP-1 expressions by ELISA.mRNA and protein of MCP-1 in fibroblast cells from 5 SSc patients and 3 healthy subjects were also measured by RT-PCR and immunohistochemistry.At the same time,the correlation between the expression levels of MCP-1 and SSc was analyzed.Results The plasma level of MCP-1 was significantly higher in pa- tients with SSc than in healthy control subjects(787?393)pg/ml versus(426?266)pg/ml,P

Objective To summarize our experience in the prevention and treatment of accessory hepatic duct injury during operation on biliary tract.Methods The clinical data of 26 cases with accessory hepatic duct were retrospectively reviewed.Results Of 26 cases,the accessory hepatic duct were type I in 38.5%(10/26),and no complications including bile leakage,biliary infection and obstructive jaundice developed after division and ligation of the accessory hepatic duct;26.9%(7/26) were type II,among which,the accessory hepatic duct were injured in 3 cases,but no case developecl complications after relevant treatment;23.0%(6/26) were type III,among which,injury of accessory bile duct occurred in 2 cases.Of them,1 case developed bile leakage and was cured by reoperation.7.7%(2/26) were type IV and 3.9%(1/26) was type V.The cases of type IV and V were not damaged.Conclusions To prevent injury of accessory hepatic duct,pre-and intra-operation identification of the condition is very important,and especially by intraoperative cholangiography.Different types of accessory hepatic duct injury should be treated by different approaches. Accessory hepatic duct of type I might be cut and ligated.Type II accessory bile duct which(enters) the cystic duct and should be protected,but,if damaged,different methods of treatment are used,(depending) on the caliber of accessory hepatic duct.Type III and IV also should be protected,but,when damaged,the accessory hepatic duct should be repaired or performed an internal draining.

Objective To explore the effect of exogenous adrenomedullin(ADM) on expressions of glutathion in plasma and brain tissue inneonatal rats with hypoxic-ischemia reperfusion brain damage(HIRBD) and the mechanism of action.Methods Fifty-six cases of 7 d SD rats were randomly divided into 4 groups including normal control group(without any treatment),HIRBD group(the model with hypoxia for 2 h and ischemia for 1 h),primed group(abdomen infusion of ADM at 0.5 h before making model,the other was same to the HIRBD group)and treatment group(abdomen infusion of ADM at onces after making model,the other was same to the HIRBD group).The neonatal rats in 4 groups were derived blood and brain tissue after decapitation at either 4 h or 24 h after reperfusion.The levels of gtutathion(GSH) in plasma and brain tissue were determined by using chromatometry.Results In HIRBD group,the affection areas at 24 h after reperfusion enlarged compared with those at 4 h after reperfusion.Meanwhile,the affection of punctiform degeneration or necrosis at 4 h after reperfusion transformed into the affection of lamellar or diffuse degeneration or necrosis at 24 h after reperfusion.The levels of GSH in plasma and brain tissue in HIRBD group at either 4 h or 24 h after reperfusion were significantly lower than that in normal control group(Pa0.05).Meanwhile the pathology score of brain section in primed group and treatment group were significantly lower than that in HIRBD group at either 4 h or 24 h after reperfusion(Pa0.05).Conclusion Exogenous ADM can induce the neuroprotection in HIRBD by adjusting the expression of GSH.

Objective To analyze the sequence of microsatellite and the flanking sequence from four populations of Oncomelania hupensis. Methods We cloned 159 SSR-PCR amplification products of a commonly used primer, (CA)8RY, using O. hupensis genomie DNA as template, and sequenced 82 products Results The sequences obtained were novel O. hupensis genomic sequences but not repeat simple sequence. It was observed that 36 out of 82 clones contained microsatellites between priming sites.The flanking sequences of certain microsatellite were invariant. Both (GA/CT). and (TTAGGG/CCCAA)n were found in four populations of O. hupensis. However, (CAA)n were found only in O. hupensis from Fuqing,Fujian province and (TCTCTG), were found only in O. hupensis from Guichi,Anhui province and (GAA/TTC)n, (CAA/TTG)n, (CAT), were found only in O.hupensis from Puge,Sichuan province. Conclusion The results obtained by SSR-PCR should not be interpreted as the amplification of microsatellite loci, and analytical rules similar to those for Random Amplified Polymorphic DNA should be used. SSR-PCR could not make the most of the priority of microsatellite. It seems better to amplify the microsatellites with the primers designed on the basis of the flanking sequence.
