Objective To analyze the curative effects and complications of ventriculo-peritoneal shunt in treating hydrocephalus caused by different diseases in children. Methods The data of 289 children with hydrocephalus who were performed ventriculo-peritoneal shunt were examined and the incidence rate of complications was analyzed. Results Thirty-seven incidences of complications occurred in 24 patients with the total incidence rate of 12.46%.There was obstruction of proximate tube in five cases,distal end in two cases,with the obstruction rate of 2.42%.Postoperative infection happened in nine cases(3.11%).Bacterial culture was positive in three cases,two of which were Staphylococcus epidermidis and Bacillus coli in the other one.Negative results were found in six patients for the bacterial culture.Subdural hematoma occured in one case,and tube break after injury in two cases.Slit ventricle syndrome broke out seven times in three cases,leakage of cerebrospinal fluid in two,exposure of pumps in three,and subcutaneous hydrops in two.Four cases(1.38%)were dead from infection. Conclusion Ventriculo-peritoneal shunt is preferred for hydrocephalus in children if the complications are well prevented and controlled.

Objective To study the adsorption and separation of licorice flavonoid with macroporous resins. Methods Eight types of macroporous resin were selected to compare their performances in absorbing and desorbing licorice flavonoid. The optimal type for licorice flavonoid was decided, meanwhile, its kinetic curve and dynamic absorbing behavior were studied. Results HPD300 resin possessed higher adsorption and desorption capacity. The appropriate adsorption and desorption conditions were as follows:concentration of sample was 2.0 mg/mL, velocity of sample solution was 1.5 BV/h, volume of sample solution was 2 BV (bed volume);velocity of 80%ethanol was taken as eluant 1.5 BV/h, and the volume was 3 BV. Flavonoid content was increased more than 2 times under above conditions. Conclusion HPD300 macroporous resin showed better comprehensive adsorption property. It can be used to purify and separate licorice flavonoid.

Objective: To determine the protective effect of zero-balanced ultraifltration and modiifed ultraifltration on infants’ pulmonary function atfer cardiac surgery. Methods: Sixty infants with congenital heart diseases were randomly divided into 3 groups: a zero-balanced ultraifltration group (Z group), a modiifed ultraifltration group (M group) and a zero-balanced ultraifltrationwith modified ultrafiltration group (Z+M group). Oxygenation index (OI), difference of alveoli-arterial oxygen pressure (P(A-α)O2), static lung compliance (Cstat), and airway resistance (Raw) were measured before caridopulmonary bypass (CPB, T1), 20 minutes atfer the CPB (T2), 2 h atfer the operation (T3), 6 h atfer the operation (T4) and 12 h atfer the operation (T5). hTe time of mechanical ventilation was also monitored. Results:Atfer the CPB, OI and Cstat in all groups decreased signiifcantly, while Raw and P(A-α)O2 increased signiifcantly. At T3, T4 and T5, OI and Cstat in the Z+M group were signiifcantly higher than those in the Z group and the M group (P<0.05), Raw andP(A-α)O2 in the Z+M group were signiifcantly lower than those in the Z group and the M group (P<0.05). hTe ventilation time in the Z+M group was signiifcantly shorter than that in the Z group and the M group (P<0.05). Conclusion:Zero-balanced ultrafiltration and modified ultrafiltration can effectively promote the pulmonary function atfer cardiac surgery in infants.

Objective To investigate the effect of chymase on the proliferation of rat cardiac fibroblasts (CFs) and the role of transforming growth factor-?1 (TGF-?_1).Methods Cultured CFs of neonatal SD rats were isolated by trypsinization.Cell number and DNA synthesis were evaluated by MTT assay (A_(490) value) and [~3H]-deoxythy- midine [~3H]-TdR incorporation.The mRNA expression of TGF-?_1 in CFs was determined by RT-PCR.Results Chymase increased CFs numbers and [~3H]-TdR incorporation in a dose-dependent manner.The A_(490) value of CFs stimulated by 15,30 and 60 ng/mL chymase was 0.263?0.033,0.348?0.031 and 0.387?0.026,respectively, which were all significantly higher than that of control (0.201?0.019,P

Despite significant progress in medical therapy for ulcerative colitis, surgical intervention is still required in a portion of patients with ulcerative colitis. Ileal pouch-anal anastomosis has been commonly used in western countries, while ileorectal anastomosis may be appropriate in specific scenarios. The surgical decision should be made based upon the clinical situation and sufficient patient consent.

OBJECTIVETo compare the clinical safety and efficacy of laparoscopic versus open colorectal resection in octogenarians. Methods Studies comparing laparoscopic colorectal resection with open colorectal resection in octogenarians were identified from the Medline, Embase, Ovid, and Cochrane databases from 1990 to 2012. The methodological quality of the selected studies was assessed to determine studies suitable for inclusion. Meta-analysis was performed by fixed or random effects model.

RESULTSFive observational studies with a total of 685 patients (330 laparoscopic colorectal resections and 355 open colorectal resections) were identified. Laparoscopic colorectal resection was associated with a prolonged operative time (WMD=27.89, P<0.01) and a lower rate of overall complications (OR=0.58, P<0.01), wound infection (OR=0.50, P<0.05), cardiovascular complication(OR=0.53, P<0.05), quicker bowel function return (WMD=-0.83, P<0.01), and shorter length of hospital stay (WMD=-3.60, P<0.05). No differences were found with regard to anastomotic leak (OR=1.13, P>0.05), prolonged ileus (OR=0.71, P>0.05), respiratory complication (OR=0.59, P>0.05),mortality (OR=0.67, P>0.05), and reoperation (OR=0.85, P>0.05).

CONCLUSIONLaparoscopic colorectal resection is as safe as open colorectal resection, and is more favorable in terms of length of hospital stay and bowel function return in octogenarians.

BACKGROUNDDiagnosis and appropriate treatment of multidrug-resistant tuberculosis (MDR-TB) remain major challenges. We sought to elucidate that persons who share a household with drug resistance tuberculosis patients are at high risk for primary drug resistance tuberculosis and how to prevent these outbreaks.

METHODSWe used 12-locus mycobacterial interspersed repetitive unit and 7-locus variable-number tandem repeat to identify household transmission of extensively drug resistant and multiple drug resistant Mycobacterium tuberculosis in three families admitted in Shanghai Pulmonary Hospital affiliated with Tongji University. Drug susceptibility tests were done by the modified proportion method in the MGIT 960 system in the same time. Clinical data were also obtained from the subjects' medical records.

RESULTSAll of the six strains were defined as Beijing genotype by the deletion-targeted multiplex PCR (DTM-PCR) identification on the genomic deletion RD105. Strains from family-1 had the same minisatellite interspersed repetitive unit (MIRU) pattern (232225172531) and the same MIRU pattern (3677235). Strains from family-2 had the same MIRU pattern (2212261553323) and the same MIRU pattern (3685134). Strains from family-3 did not have the same MIRU pattern and they differed at only one locus (223326173533, 223325173533), and did not have the same VNTR pattern with two locus differed (3667233, 3677234).

CONCLUSIONSHousehold transmission exists in the three families. A clear chain of tuberculosis transmission within family exists. Tuberculosis susceptibility should be considered when there is more than one tuberculosis patients in a family. Household tuberculosis transmission could be prevented with adequate treatment of source patients.

BACKGROUNDAllergic asthma is associated with airway inflammation and hyperresponsiveness caused by dysregulated production of cytokines secreted by allergen-specific helper T-type 2 (Th2) cells. The linker for activation of T cells (LAT) is a membrane-associated adaptor protein, which has been shown to take part in regulating T cell receptor (TCR) signaling and T cell homeostasis. In this study, we established an asthmatic mouse model to examine the changes in LAT levels during allergic airway disease and the effects of LAT transgenic expression on airway inflammation.

METHODST cells from mouse lung tissues were isolated from allergen challenged (ovalbumin (OVA)) and control mice, and the purity of these isolated T cells was examined by fluorescence-activated cell sorter (FACS). Semi-quantitative RT-PCR and Western blotting were used to detect the expression of the LAT gene and LAT protein, respectively. After an intranasally administered mixture of pCMV-HA-LAT plasmid and Lipofectamine 2000, 24 hours before and 72 hours after allergen challenge, the BALF cell count and the differential cytologies were studied. In addition, IL-4 and IFN-γ levels in the BALF were determined by ELISA, and pathological changes in lung tissues were observed.

RESULTSLAT protein and mRNA expression were decreased in lung T cells in a mouse model of allergen-induced airway disease. After intranasal administration of pCMV-HA-LAT, histopathological examination of the lungs showed that intervention with LAT overexpression prevented mice from developing airway inflammation, and the number of total cells, eosinophils, neutrophils, and lymphocytes in the BALF was reduced significantly compared with the OVA sensitized and challenged group. In addition, the Th2 cytokine IL-4 decreased, while the Th1 cytokine IFN-γ increased compared to the OVA sensitized and challenged group or the OVA sensitized group plus pCMV-HA treatment.

CONCLUSIONThis study demonstrates that LAT might effectively diminish Th2 cytokine responses, lung histopathological changes and lung inflammation to allergen challenge in a model of experimentally induced asthma.

OBJECTIVETo study the protective effect of astragaloside IV (AS IV) on H2O2 induced human mesangial cells (HMC), and further explore its molecular mechanism.

METHODThe cultured mesangial cells were divided into 5 groups: the normal control group, the H2O2 model group, the AS IV (12.5, 100 nmol x L(-1)) group and the Tempol (1 x 10(5) nmol x L(-1)) group. The MTT method was used to observe cell viability. Hoechst 33258 staining was used to observe the HMC apoptosis and DHE staining was used to detect the generation of reactive oxygen species (ROS). The flow cytometry was used to detect the changes in cell cycle. Western blot was used to detect the expression of Cyclin D1, CyclinA, p38, and T-p38.

RESULTH2O2 (1 x 10(5), 2 x 10(5), 3 x 10(5), and 4 x 10(5) nmol x L(-1)) could induce HMC oxidative stress injury, with significant decrease in the cell survival rate. AS IV (100 nmol x L(-1)) could significantly inhibit HMC oxidative stress injury induced by H2O2 (3 x 10(5) nmol x L(-1)), increase the survival rate of HMC cells, inhibit cell apoptosis, and decrease intracellular ROS production. AS IV could also increase the expression of Cyclin D1, recover normal cell proliferation, and decrease the expression of p38.

CONCLUSIONAS IV can protect H2O2 induced oxidative stress injury in mesangial cells. Its mechanisms may be related to inhibiting the p38/MAPK signaling pathway, increasing the expression of Cyclin D1 and decreasing the intracellular ROS oxidative stress injury.
