Objective To evaluate the efficacy and safety of the combination of Weimaining capsule and XELOX regimen (oxaliplatin plus capecitabine) in the treatment of advanced gastric cancer patients.Methods A total of 62 patients with advanced gastric cancer who fulfilled all predetermined criteria were randomly divided into observation group and control group.The 31 patients in observation group received a combination of Weimaining capsule and XELOX regimen,the 31 patients in control group received only XELOX regimen at the same dose intensity.Each patient received at least two cycles (1 cycle =21 days) of treatment,the efficacy was assessed after two cycles.Results The median time-to-progression (TTP) of observation and control groups were 5.5 and 4.8 months,respectively.The difference had no statistical significance (P =0.238).The disease control rates (DCR) of observation group was significantly improved compared with control group [67.7 ％ (21/31) vs 41.9 ％ (13/21),P ＜ 0.05],the difference was statistically significant,while the objective response rate (ORR) of the 2 groups had no statistical difference [(32.3 ％ (10/31) vs 25.8 ％ (8/31),P ＞ 0.05].In drug safety aspects,there was no Ⅴ grade adverse reactions (deaths caused by drug) among all the patients.Rates of grades Ⅱ-Ⅳ neutrocytopenia and nausea,vomiting in observation group were obviously lower than control group [16.13 ％ (5/31) vs 38.71％ (12/31),P ＜ 0.05;12.90 ％ (4/31) vs 35.48 ％ (11/31),P ＜ 0.05],other adverse reactions between the 2 groups had no statistical difference.Conclusions A combination of Weimaining capsule and XELOX regimen in the treatment of advanced gastric cancer patients can improve DCR significantly and reduce part of adverse reaction induced by chemotherapy with satisfactory safety.This method is worthy of application widely.

A new HPLC-UV technique for the separation and analysis of 10 monosaccharides achieved within 13.5 min using 1-phenyl-3-methyl-5-pyrazolone (PMP) as the labelling molecule of the reductive monosaccharides has been established by combining common high performance liquid chromatography-UV and C18 column. The established technique was applied to the quantification of the monosaccharide components in extract of Silybum marianum. The results showed that the tested 10 monosaccharides as PMP derivatives were baseline separated under the HPLC conditions proposed. It was confirmed that Silybum marianum extract was composed of mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, xylose, galactose and arabinose with the molar ratio of 0.66:0.84:0.58:1.0:1.6:0.69:2.7:4.8. Quantitative recoveries of the compositional monosaccharides separated from the extract were in the range of 92.4%-104.0%, and the RSD values fell within 0.68%-3.81%. The results demonstrated that the proposed HPLC method was simple, rapid, convenient, and precise, and it was applicable to the analysis of the compositional monosaccharides of Silybum marianum extract.

Objective To identify the features of the NCAM+ c-Kit+ subset of hepatic progenitor cells in the intrahepatic cholangiocarcinoma (ICC) cell line RBE.Method Magnetic activated cell sorting was used to isolate NCAM+ c-Kit+/NCAM-c-Kit-subset cells,which were tested for hepatic progenitor cell properties and proliferation,colony formation,and invasive abilities in nude mice.Resuits The cell proliferation ability of NCAM+c-Kit+ subset cells was stronger than that of NCAMc-Kit-subset cells (P＜0.01).In serum-free condition,the number of colonies formed by NCAM+c-Kit+ subset cells was more than that of NCAM-c-Kit-cells (P＜0.01).1 × 104 NCAM+c-Kit+ cells were enough to form tumors in nude mice after subcutaneous inoculation for two weeks,while 1 × 106 NCAM-c-Kit-cells were necessary to form tumors for three weeks.The tumor formation rate of NCAM+c-Kit+ cells was higher than that of NCAM-c-Kit-cells (P=0.04).Conclusions It is possible that NCAM+c-Kit+ subset cells in RBE have the properties of hepatic progenitor cells,and NCAM combined with c-Kit might be a valuable marker for isolating and purifying ICC stem/progenitor cells.

Objectives To study the age and gender distribution of clinical and non-clinical depressive symptoms in chil-dren, and the potential link between non-clinical and clinical depressive symptoms. Methods 4520 children aged 8-15 years old were screened for mental disorders by Strength and Dififculties Questionnaire (SDQ) and the Development and Well Being Assessment (DAWBA), and further assessed by the Depression Self-Rating Scale for Children (DSSC). Fifty-three children diagnosed as depressive disorder were included in clinical group and 1504 children without depression disorders whose DSSC scores≥14 were included in non-clinical group. The relationship between gender, age and DSSC scores was analyzed. Results Interaction effect on DSSC scores between gender and age was found in clinical group (F=4.40, P=0.049), but not found in non-clinical group (F=1.04, P=0.409). DSSC scores of girls were higher than that of boys in clinical group (t=2.16, P=0.048). There was no statistically signiifcant main effect of gender in non-clinical group (F=0.21, P=0.646). No signiifcant difference in DSSC scores existed among different age groups in clinical group (F=0.82, P=0.573). There was signiifcant main effect of age in non-clinical group (F=1.96, P=0.048). Conclusions There were different age and gender distribution of clinical and non-clinical depressive symptoms in children.

Objective To investigate the status and influencing factors of quality of life among diabetes patients in Nanchang,and to explore the relationships between the quality of life and community health care demands.Methods Totally 292 diabetes patients were recruited by multi-stage sampling method from thee community health service centers in Nanchang city.They were investigated with Diabetes-specific Quality of Life Scale(DSQL) and a self-designed questionnaire of community health care demands.The results underwent analysis.Results The total score of the DSQL in Nanchang was(66.88±15.44) points,which was relatively poor.The main factors affected patients' quality of life were the complications of diabetes,diabetic macroangiopathy,diabetic foot,hypertension and patients' career.The total and the every dimension of the scores of the DSQL were positively correlated with the scores of disease nursing needs and community health care demands.Conclusions To improve diabetes patients' quality of life,community diabetic care should focus on the different affected factors of patients' quality of life and the demands of patients.

Objective To investigate the correlation of the 24?hour ambulatory systolic blood pressure (SBP) and carotid intima?media thickness(CIMT) in the elderly. Methods A total of 2 464 who were more than or equal to 60 years old participants were selected with random sampling in accordance with the inclusion criteria from the retired workers in Tangshan Kailuan Company. Dynamic blood pressure monitoring, neck vascular ultrasound and other examination were performed for the participants. . Multivariable linear regression analysis was used to analyze correlation between the SBP of 24?hour, daytime and nightime with CIMT, respectively. Results ( 1) The observation population was divided into three groups according to the tertiles of SBP of 24?hour, daytime and nightime, respectively. With the levels of different SBPs inceasing, CIMT values thickened markedly ( P<0. 01 ) . ( 2 ) Multivariable linear regression analysis showed that after adjusting for confounding factors,the SBP of 24?hour,daytime and nightime associated with CIMT positively and linearly(P<0. 05),and regression coefficient(95%CI) were 0. 022(0. 009-0. 035), 0. 021(0. 008-0. 035), 0. 019 ( 0. 006-0. 032) respectively. In addition,clinic SBP step into the multivariable linear regression,and regression coefficient ( 95%CI ) were 0. 016 ( 0. 003-0. 029 ) , 0. 016 ( 0. 003-0. 030 ) , 0. 019 ( 0. 007-0. 032 ) , respectively. Conclusion The effect of increased 24?hour ambulatory SBP on CIMT was greater than the clinic SBP. Active monitoring of 24 h ambulatory blood pressure and maintaining a low level of blood pressure is essential for preventing and delaying atherosclerosis.

Objective To explore the relationship between different blood glucose levels and new carotid artery plaques.Methods A total of 5 440 participants met the inclusion criteria were selected stratified randomly from the 101,510 serving and retired workers of Tangshan Kailuan Company who participated the health examination from 2006 to 2007.The follow-up health examination were respectively preformed from 2010 to 2011 and from 2012 to 2013 which included carotid ultrasound for these 5 440 participants.The 5 440 participants were divided into three groups (ideal blood glucose group,impaired fasting glucose group and diabetic group) according to their fasting glucose levels in 2010-2011 examination.Multivariate Logistic regression analysis was used to analyze the risk factors of new carotid artery plaques.Results Among 5 440 subjects,participants whose FPG,ultrasound data incomplete and ultrasound detection of carotid plaques during the 2010-2011 health examination were excluded,then 3 084 participants were included in this study,among them,175 participants who did not participate the 2012-2013 health examination and 561 participants whose carotid plaque ultrasound data incomplete were excluded.Thus,a total of 2 348 participants were included in the present analysis.The total detection of new carotid artery plaque rate was 15.0％ (352/2 348) after 2 years of follow-up.The detection of new carotid artery plaque rate in normal glucose group(n =1724),impaired fasting glucose group(n=464) and diabetic group(n=160) were 14.2％(245/1 724),14.9％(69/464) and 23.8％(38/160),respectively.The diabetic group was higher than that of the ideal blood glucose group and the impaired fasting glucose group,the difference was statistically significant(P＜0.05).Impaired fasting glucose group and diabetic group had an increased risk of new carotid artery plaque compared with those in ideal glucose group(OR =0.924,95％CI 0.691-1.235 and OR =1.733,95％CI 1.107-2.713,respectively),the difference was statistically significant(P＜0.05).After adjusted for the other risk factors,with the risk-adjusted ratio (OR =1.117,95％CI 0.824-1.513 and OR =1.393,95％CI 0.872-2.226).Conclusion The detection of new carotid artery plaque increase in the diabetic group.However,after adjustment for other risk factors associate with emerging danger of new carotid artery plaque is no significant difference.This requires more long-term follow-up study of a large sample to be further confirmed.

OBJECTIVE:To explore the effects of early treatment with mouse nerve growth factor on the wound healing in aged patients with electric burn. METHODS:78 elderly patients with electric burn were divided into control group and observation group by random number table method,with 39 cases in each group. Control group was given routine method for electric burn, and observation group was additionally given Mouse nerve growth factor for injection 30 μg dissolved in 2 ml 0.9% Sodium chlo-ride injection within 24 h,im,qd,on the basis of control group. Treatment course of 2 groups lasted for 2 weeks. Clinical effica-cies of 2 groups were compared as well as VAS score before treatment,3,5,7 days after treatment. The survival rate of skin flaps and the rate of wound healing 3,5,7 days after treatment,the recovery of wound scar,the value of wound blood perfusion,the time of complete wound healing and the occurrence of ADR were also compared. RESULTS:The total effective rate of observation group(94.9%)was significantly higher than that of control group(66.7%),with statistical significance(P<0.05). 3,5,7 days after treatment,VAS score of observation group was significantly lower than that of control group,and the survival rate of skin flaps and the rate of wound healing were significantly higher than those of control group,with statistical significance(P<0.05). Af-ter treatment,VSS score of observation group was significantly lower than that of control group,while the value of wound blood perfusion was significantly higher than that of control group;the time of complete wound healing was significantly lower than that of control group,with statistical significance (P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Early treat-ment with mouse nerve growth factor for elderly patients with electric burns can effectively lower the VAS and VSS score,improve the survival rate of skin flaps and the rate of wound healing,increase the value of wound blood perfusion and shorten the time of complete wound healing with good clinical efficacy and safety.

Objective: To investigate the relationship of PD-L1 protein expression and gene amplification in gastric cancer and their correlation with clinicopathologic factors. Methods: The cohort included 247 gastric cancer specimens with follow-up data and clinicopathologic data obtained from Shanxi Cancer Hospital in 2011. PD-L1 expression was detected by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH). Results: PD-L1 protein was expressed in 25.9% (64/247) of the tumor cells and 26.7% (66/247) of the tumor infiltrating immune cells (IC). There was a correlation between the two (P<0.01). The expression of PD-L1 in tumor cells correlated with the degree of differentiation and tumor diameter(P<0.05). The PD-L1 expression in IC correlated with vascular tumor thrombi(P<0.05). The amplification rate of PD-L1 gene detected by FISH was 19.0% (47/247), and was associated with age, large/small curvature of the stomach, tumor location, tumor diameter, and lymph node metastasis(P<0.05). The positive coincidence rate of the two methods was 25.0% (16/64), negative coincidence rate was 83.0% (152/183), and total coincidence rate was 68.0% (168/247), suggesting that the coincidence of IHC and FISH was poor (P=0.157). There was a negative correlation between PD-L1 protein expression on tumor cells and prognosis in gastric cancer. There was no significant correlation between PD-L1 protein expression on IC and PD-L1 gene amplification with prognosis. Vascular tumor thrombi, tumor diameter, depth of invasion, and lymph node metastasis were all poor prognostic factors of gastric cancer(P<0.05). Multivariate Cox regression analysis showed that PD-L1 protein expression, depth of invasion and lymph node metastasis were all independent prognostic risk factors for gastric cancer. Conclusions Concordance between PD-L1 protein expression and gene amplification is poor. PD-L1 protein expression may signify poor prognosis. There is no significant correlation between PD-L1 gene amplification and prognosis of patients with gastric cancer.

OBJECTIVETo investigate the relationship between the use of antibiotics in a burn unit and the change in the drug - resistance of Staphylococcus aureus (S. aureus).

METHODSBy calculating the defined daily doses (DDD) of accumulated consumption of antibiotics per unit time and expense consumption, the use of different kinds of antibiotics in a burn unit in recent five years was analyzed, and correlation analysis between the change of antibiotics consumption amount and the change in drug - resistance level of S. aureus were carried out.

RESULTSAmikacin, gentamycin and cephazolin were the commonest antibiotics used in our burn unit. They were relatively cheaper than some other antibiotics. The consumption amount of compound antibiotics application was negatively correlated with the penicillin resistance level of S. aureus. Seven correlation coefficients between the consumption of first generation cephalosporins and seven coefficiences of resistance rate of S. aureus were negative. The consumption amount of the 3rd generation of cephalosporin application was positively related to the resistance of S. aureus to erythromycin and oxacillin.

CONCLUSIONAccumulated DDD might be one of the ideal indices of reflecting antibiotic use. The changes in the consumption amount of the 1st and 3rd generation of cephalosporins containing beta-lactamase-inhibitor might affect the drug-resistance levels of S. aureus to some degree.
