OBJECTIVETo investigate the association between the polymorphism of serotonin transporter gene-linked polymorphic region(5-HTTLPR) and slow transit constipation(STC).

METHODSPolymerase chain reaction was used to assess 5-HTTLPR polymorphism of SERT gene in 54 patients with STC and 100 healthy controls.

RESULTSThe frequencies of serotonin transporter short/short(S/S) and allele S genotypes were significantly higher in STC patients than those in controls(72.2% vs 50.0%; 83.3% vs 72.5%; both P< 0.05). There were no significant differences in 5-HTTLPR polymorphism respectively between the two groups according to gender and age(less than 45 and more than 45 years old). The frequency of S/S genotype was higher in the patients with less than 40% of the ingested markers evacuated within 72 h than those with more than 40% evacuated(71.7% vs 42.6%, P< 0.05).

CONCLUSIONThe presence of 5-HTTLPR allele S may contribute to the pathogenesis of STC.

Objective To investigate the correlation between the CT perfusion and microvessel density (MVD),expression of vascular endothelial growth factor(VEGF)in neoplasm of head and neck.Methods Eighty-eight lesions of head and neck were scanned by spiral CT.The largest axial surface of the mass was searched on unenhanced imaging,and at this level the dynamic contrast enhanced scan series was acquired.Time-density curves (TDC)were created from circular or oval regions of the interest drawn over the mass,target artery by Toshiba Xpress/SX spiral CT with perfusion functional software.The parameters were measured including:peak height (PH ),peak time (PT ),mean transit time (MTT), contrast enhancement ratio(RPH),and perfusion flow (PF).Histopathological slides of 35 masses were carefully prepared for the anti-CD34 and VEGF immunohistochemical staining and tumor microvessel density and calculation of VEGF expression scores.The parameters of CT perfusion were correlatively study with MVD and VEGF.Results(1)The TDC of CT perfusion imaging could be classified into 3 types.The TDC of 53/77 (68.9% )malignant tumors presented the type with rapid ascending and rapid descending after injecting contrast.The TDC of 6/9 malignant lymphomas showed low platform curve。(2)The PF median of thyroid carcinoma was 82.2(41.0,183.4)ml?min~(-1)?100 g~(-1).There was significantly difference in the parameters of CT perfusion among thyroid carcinoma and squamaous cell cancer (Median 23.8 (7.0, 108.4)ml?min~(-1)?100 g~(-1))and lymphomas (Median 24.5(13.2,78.6)ml?min~(-1)?100 g~(-1)).(3) MVD in benign tumors was (44.7?3.4),and in malignant tumors,it is (49.6?14.8 ).There was no significantly difference in MVD between benign and malignant tumors.High VEGF expression was found in 15 malignant tumors and 1 benign tumors,low VEGF expression was found in 9 malignant tumors and 10 benign tumors.(4)There were no significantly difference in VEGF expression and MVD.There was good correlation between MVD (M 40.0 )and PH (M 26.9 ),RPH (M 14.5 ),PF (M 46.8 )(r = 0.35,45.49, 0.41 ).There was correlation between VEGF(M 4.0)and MTT(M 16.7 )(r = -0.41 ).Conclusion The TDC and CT perfusion could be helpful to differentiate benign from malignant tumors. CT peffusion in neoplasm of head and neck is correlated with MVD and VEGF,and may reflect MVD and expression of VEGF.

Diacylglycerol, DAG, because of its multifunctional and nutritional properties, attracted considerable attention recently. Enzymatic synthesis of diacylglycerols from linoleic acid was investigated in a solvent-free reaction in a continuously operated fixed bed reactors containing Lipozyme RM IM. By appropriate manipulation of the fluid-residence time, the relative proportions of the various acylglycerols in the effluent stream can be controlled. In addition, the presence of excess glycerol is effective for the removal of water produced during the esterification reactions. Under the conditions of molar ratio of linoleic acid to glycerol of 0.5, the immoblized enzyme maintained high stability and allowed the reaction to continue for 10 days without significant deterioration in enzyme activity. It was determined that the conversion of fatty acid, content of 1,3-DAG and volume efficiency of reactor reached optima under the conditions: a packaged-bed reactor(with a ratio of packed length to inner diameter of 7.8), reacting temperature at 65 degrees C, molar ratio of linoleic acid to glycerol of 0.5, and feeding flow rate of 1.2 mL/min.

OBJECTIVETo investigate the reasonable proposal of prophylactic antibiotics use in selective colorectal operation.

METHODSOne hundred and sixty-five patients underwent colorectal surgery were randomized to Treatment 1 (55 cases), Treatment 2 (50 cases) and Control (60 cases) group. The Treatment 1 group was given oral MgSO4 solution at the night before operation, and Cefradine 2.0 g (I.V.) during the induction of anesthesia, continued with tow times of intravenous Cefradine 2.0 g and 0.5% Metronidazole 100 ml at an interval of 12 hours in 24 hours after the operation. The Treatment 2 group was given the same treatment as Treatment 1, but the antibiotics would not be withdrawn until 3-5 d after operation. On the basis of the treatment of Treatment 2 group, the Control group was given oral antibiotics 2-3 days before operation. Postoperative complications including surgical site infection, stoma leakage, dysbacteriosis, and WBC, body temperature, days of hospitalization and antibiotic expenses in the three groups were observed and compared.

RESULTSThere was no significant differences in surgical site infection, stoma leakage, WBC counting and its change, body temperature and hospital stay among the three groups (P > 0.05). The incidence rate of dysbacteriosis in Control group was significantly higher than that in Treatment 1 group (P < 0.05). The antibiotic expenses in the Treatment 1 group was significantly lower than those of the other two groups (P < 0.05).

CONCLUSIONSProphylactic antibiotic use during the induction of anesthesia and 24 hours after operation was reasonable in selective colorectal operation, it can prevent the surgical site infection effectively with good social-economic effects and fewer side effects.

ABSTRACT:OBJECTIVE To explore the mechanism of treating Alzheimer's disease model rats by electro-acupuncture through detecting the phosphorylation of p38MAPK and tau protein in hippocampus.METHODS SD rats were randomly di-vided into control group,sham-operated group,model group and electric-acupuncture group.The model group and electric-ac-upuncture group were injected with Aβ1-40 into hippocampus.20 d later,the electric-acupuncture group had electric-acupuncture at Baihui(GV20) and Shenshu(BL23)appoints.Morris Water Maze was used to observe rates memory abilities,and western blot and immunohistochemistry were used to determine the expression of p-p38MAPK and p-tau181.RESULTS The electric-acupuncture group significantly improved learning and memory abilities(P <0.05);expression of p-p38MAPK and p-tau181 in the model group was significantly higher than the others,while significantly reduced after electric-acupuncture treatment(P <0.05).CONCLUSION Acupuncture can regulate expression of p-tau181 through p38MAPK signaling pathway and improve the learning and memory ability of AD rats.

Objective To investigate the clinical features and prognosis of acute pancreatitis(AP)complicated with metabolic syndrome(MS).Methods 139 AP patients were retrospectively selected and divided into MS group(76 cases)and non-MS group(63 cases),general data of the two groups were collected and analyzed;conservative treatment was given to 2 groups of patients,and the general conditions,laboratory indicators,comorbidities,and related indicators of disease severity of the two groups were compared and analyzed,and the influencing factors of poor prognosis in patients(AP combined with MS)were analyzed.Results Compared with non-MS group,HDL,Ca2+in MS group decreased significantly,Body weight、Body Mass Index(BMI)、diabetes mellitus、hypertension(systolic/diastolic blood pressure)、hyperlipidemia、white blood cell count、CRP、PCT、IL-6、FPG、UA、TC、TG、TyG、TYG-BMI and non-traditional lipid parameters TC/HDL-C、TG/HDL-C、LDL-C/HDL-C and non-HDL-C were significantly increased.There were no significant differences in age、sex、length of stay、BUN、CREA、LDL-C、ALT and AST between the two groups(P＞0.05);BMI,white blood cell count,CRP,IL-6,FPG,UA,TC,TG,TyG,TYG-BMI,TC/HDL-C,TG/HDL-C,LDL-C/HDL-C,and non-HDL-C were independent risk factors for poor prognosis in AP patients with MS,and HDL-C was a potential protective factor for prognosis in AP patients with MS,the difference was statistically significant(P＜0.05).Conclusion With the change of modern lifestyle,there are more and more MS patients,and the incidence of MS patients with AP is gradually increasing.TyG,TYG-BMI and non-traditional lipid parameters are novel,convenient and practical markers for clinical evaluation,which have a high diagnostic and predictive value for AP with MS metabolic abnormalities,and provides clinical basis for management and intervention.

OBJECTIVETo evaluate the relationship between mortality and HBVDNA and HBeAg expression of severe hepatitis B patients.

METHODSThe mortality rates of different types of severe hepatitis patients in our hospital during the last five years were analysed. HBV DNA was detected using the fluorescence quantitative PCR method and the HBeAg expression of severe hepatitis B was studied using a microparticle method.

RESULTS(1) Hepatitis B morbidity was 83.5% in each type of severe hepatitis, and severe chronic hepatitis B morbidity was 96.77% in each type of severe chronic hepatitis. (2) The mortality rate of those with HBV DNA more than 1 x 10(5) copies/ml was 53.25% and the mortality of those with HBV DNA less than 1 x 10(5) copies/ml was 34.50% (P less than 0.01). The HBeAg expression had no influence on the death rate. (3) The death rate descended to 30.38% from 54.64% (HBV DNA more than 1 x 10(5) copies/ml) when treated with Lamivudine (P less than 0.01).

CONCLUSIONIn severe hepatitis the quantity of virus carried in the patient is one of the key factors of mortality; antivirus treatment can lower mortality.

OBJECTIVETo explore methods of preventing and reversing rejection after simultaneous pancreas-kidney (SPK) transplantation.

METHODSSeventeen patients underwent SPK transplantation from September 1999 to September 2003 were reviewed retrospectively. Immunosuppression was achieved by a triple drug regimen consisting of cyclosporine, mycophenolate mofteil (MMF), and steroids. Three patients were treated with anti-CD3 monoclone antibody (OKT3, 5 mg x d(-1)) for induction therapy for a mean period of 5-7 days. One patients received IL-2 receptor antibodies (daclizumab) in a dose of 1 mg x kg(-1) on the day of transplant and the 5th day posttransplant. One patient was treated with both OKT3 and daclizumab for induction.

RESULTSNo primary non-functionality of either kidney or pancreas occurred in this series of transplantations. Function of all the kidney grafts recovered within 2 to 4 days after transplantation. The level of serum creatinine was 94 +/- 11 micromol/L on the 7th day posttransplant. One patient experienced the accelerated rejection, resulting in the resection of the pancreas and kidney grafts because of the failure of conservative therapy. The incidence of the first rejection episodes at 3 months was 47.1% (8/17). Only the kidney was involved in 35.3% (6/17); and both the pancreas and kidney were involved in 11.8% (2/17). All these patients received a high-dose pulse of methylprednisone (0.5 g x d(-1)) for 3 days. OKT3 (0.5 mg x d(-1)) was administered for 7-10 days in two patients with both renal and pancreas rejection. All the grafts were successfully rescued.

CONCLUSIONRejection, particularly acute rejection, is the major cause influencing graft function in SPK transplantation. Monitoring renal function and pancreas exocrine secretion, and reasonable application of immunosuppressants play important roles in the diagnosis and treatment of rejection.

OBJECTIVETo demonstrate the association of tumor budding with clinicopathological features and prognosis in T2 rectal cancer.

METHODSClinicopathological data of 123 patients who underwent potentially curative resection for T2 rectal carcinoma between 2001 and 2005 at the Changhai Hospital were collected. All pathology slides were stained with hematoxylin and eosin for microscopic examinations. The maximum value of tumor buds(MV) and average value of tumor buds(AV) were calculated, which were classified as low value (≤5), median value (5 < bud value < 10), and high value (≥10).

RESULTSUnivariate analysis and multivariate analysis revealed that MV(P=0.000), AV(P=0.001), and lymphatic invasion (P=0.006) were independent predictors for lymph node metastasis in T2 rectal cancer. Neural invasion and poorly differentiation were significantly associated with MV(P<0.05). Neural invasion, vascular invasion and poorly differentiation were were significantly associated to AV (P<0.01). Disease-free survival (DFS) of patients with low AV, median AV and high AV was 110.5 months, 95.8 months, and 60.0 months respectively. There were significance differences in DFS of low AV with median and high AV(P<0.05). DFS of patients with low MV, median MV and high MV was 115.1 months, 98.5 months, and 86.0 months respectively. There were significance differences in DFS between low and high AV, and median and high MV(P<0.01 and P<0.05), while no significant difference existed between low and median MV.

CONCLUSIONTumor budding is a useful marker to indicate high invasiveness of rectal cancer and a valuable prognostic predictor.
