Objective: To investigate the mechanisms responsible for the neuroprotection by cholecystokinin octapeptide against glutamate-induced apoptosis in vitro cultured cortical neurons. Methods: Primary cultured corticaI neurons from SD rats of 0～24 hold were incubated for 8 days. The cultured cells were divided randomly into three groups: control group,glutamate group and CCK group. In the controI group,cells were not treated with glutamate orCCK;Neurons in glutamate group were incubated with 50?mol/Lglutamate for 30 min;In CCK group,CCK-8 was added to the Neurons 24 h prior to incubation with glutamate. After injuried by glutamate,cells in all the groups were incubated with normal medium for 0,6,12,24 h and 48 h. At the five time points,cells were fixed respectively for experiment. Cell viability were determined by the colorimetric MTT assay;The protein expression of Bcl-2,Bax and Caspase-3 were determined by immunocytochemistry techniques. Results:Pretreatment with CCK for 24 h significantly improved glutamate-induced suppression of cell viability. Pretreatment with CCK also completely reversed the suppression of Bcl-2 expression,and significantly inhibited Bax overexpression and Caspase-3 activition induced by glutamate. Conclusion:Theneuroprotective mechanisms of CCK against glutamate-induced apoptosis in cultured cortical neurons may be associated with up-regulation of Bcl-2/Bax ratio and down-regulation of Caspase-3.

Objective To study the pathological spectrum of neonatal sepsis and antibiotic resistance of bacteria and fungi isolated from neonatal blood samples. Methods Clinical information of neonates with sepsis admitted to neonatal ward of our Hospital were retrospectively collected from January 2007 to December 2014 and analyzed. Results During the study period, a total of 23 224 infants were admitted to neonatal ward. Among them, 608 were diagnosed with sepsis (2. 62% , 608 / 23 224). Blood culture samples were positive in 412 cases, the rest (196 cases) were diagnosed according to clinical manifestations and laboratory tests. The composition ratio of sepsis during the first 4 years was significantly lower than that of the subsequent 4 years (2. 58% , 225 / 9 805 vs. 2. 85% , 383 / 13 419, P < 0. 05). Of 412 bacterial strains isolated, gram-positive bacteria, gram-negative bacteria and fungi accounted for 62. 38% , 30. 34% and 7. 28% , respectively. For the 155 strains isolated during first 4 years, the number of G + bacteria, G - bacteria and fungi were 106 strains (68. 39% ), 40 strains (25. 81% ), 9 strains ( 5. 81% ), respectively. The coagulase-negative staphylococcus ( CONS ) accounted for 90. 57% of G + strains. Klebsiella pneumoniae and Escherichia coli accounted for 50. 00%and 15. 00% of G - strains respectively. 257 strains were isolated during the subsequent 4 years, of which G + bacteria, G - bacteria and fungi accounted for 151 strains (58. 75% ), 85 strains (33. 07% ), 21 strains (8. 17% ), respectively. CONS accounted for 74. 83% of G + strains, Klebsiella pneumoniae and Escherichia coli accounted for 30. 58% and 35. 29% of G - strains. The composition ratio of CONS and Escherichia coli were significantly different between first and subsequent 4 years (P < 0. 05). G +bacteria were resistant to penicillin, oxacillin and macrolide, sensitive to piperacillin / tazobactam and quinolone. We did not identify any G + strain resistant to vancomycin. In general, G - bacteria were resistant to ampicillin and cephalosporins, sensitive to the beta lactamase inhibitor compound preparation and quinolones, and highly sensitive to carbapenems. Fungi generally were sensitive to conazoles. Conclusions Neonatal sepsis are mainly caused by CONS, Klebsiella pneumoniae and Escherichia coli also play important roles. G + bacteria and G - bacteria in general are resistant to penicillin and cephalosporins. All G + bacterial strains isolated from our cohort are sensitive to vancomycin. G - bacteria are generally sensitive to carbapenems. Fungi generally are sensitive to conazoles.

Objective To investigate the correlation between hepatitis B virus (HBV)drug -resistance gene mutations and hepatocellular carcinoma (HCC).Methods The clinical data of treatment -experienced patients,who underwent examination for HBV drug -resistance gene mutations in Beijing Ditan Hospital from January 1 to December 31,2013,and still had detectable HBV DNA after being treated with nucleos(t)ide analogues,were collected.All the patients were followed up,and the development of HCC was considered as the clinical out-come.The correlation between drug -resistance gene mutations and the development of HCC in patients with HBV infection was analyzed. The chi -square test was used for comparison of categorical between groups,the t -test was used for comparison of continuous data between two groups,and the log -rank test was used for comparison of the incidence of HCC between two groups.Results A total of 227 patients were enrolled in this study.According to the results of the detection of HBV drug -resistance gene mutations,103 patients (103 /227, 45.37%)had no drug -resistance gene mutations and 124 (124 /227,54.63%)had drug -resistance gene mutations.There were no sig-nificant differences between the mutation group and the non -mutation group in HBV DNA load (5.19 ±1.60 log10 IU /ml vs 5.44 ±1.75 log10 IU /ml,t =-1.134,P =0.258)and the percentage of patients with liver cirrhosis (24.19% (30 /124)vs 16.50% (17 /103),χ2 =2.026,P =0.155).The median follow -up was 28 months (range 4 -58 months),and the incidence of HCC was 7.49% (17 /227).A-mong the patients with HBV drug -resistance gene mutations,12 (12 /124,9.68%)developed HCC,and among those without HBV drug-resistance gene mutations,5 (5 /103,4.85%)developed HCC.Among the patients who developed HCC,70.59% (12 /17)had HBV drug -resistance gene mutations at baseline;among the patients who did not develop HCC,53.33% (112 /210)had HBV drug -resistance gene mutations at baseline.Conclusion The patients with poor control of HBV DNA during antiviral therapy have a comparable incidence of HCC to those not treated with antiviral therapy,with a relatively high risk of developing HCC;the treated patients with HBV drug -resist-ance gene mutations may have a higher risk of HCC than those without such mutations,which needs to be confirmed by the studies with a longer follow -up period and a larger sample size.

Objective To investigate the clinical significance of the joint detection of platelet parameters and coagulation function markers in hepatitis patients.Methods 310 patients with viral hepatitis were divided into 4 groups:acute hepatitis group,chronic hepatitis group,serious hepatitis group and hepatocirrhosis group.The control group was the 80 healthy examination eligible people.Each group were detected platelet parameters ( PLT), mean platelet volume( MPV),.platelet distribution width( PDW),platelet large cell ratio( P-LCR), prothrombin time( PT) ,activated partial thromboplasin time (APTT ) , thrombin time ( TT) and factorl ( Fbg).Results The levels of PLT,MPV and Fbg were obviously reduced in chronic hepatitis,serious condition chronic hepatitis patients and hepatocirrhosis had significant difference compared with those in the control group (all P < 0.01).Moreover, the levels of PDW,P-LCR,PT,APTT and TT were obviously increased in the four groups compared with the control group(all P <0.05 ).Conclusion The joint detection of platelet parameters and coagulation function markers could help to observe the degree of progression of virus hepatitis,and had important clinical significance for the treatment and prognosis.

There are various kinds of antihypertensive agents with complex chemical structures. Common antihypertensive agents are divided into 5 classes, including diuretics, calcium antagonists, angiotensin-converting enzyme inhibitors, angiotensin Ⅱ receptor blockers and β-blockers, and can cause various types of drug eruptions. This review summarizes clinical characteristics, possible pathogenesis, treatment and consequences of antihypertensive agent-induced drug eruptions, including angioedema, and lupus erythematosus-like, psoriasis-like, eczematoid, herpetiform or lichen planus-like drug eruptions, in hope to facilitate their early detection, diagnosis and treatment, and to provide information and ideas for clinical and basic researches into them.

Skin microbiome maintain homeostasis with the host, and affect skin barrier and immune function. The components of skin microbiome are diverse and specific, and are affected by multiple factors. The predominance of Staphylococcus aureus and decrease in diversity of skin microbiome are a characteristic of atopic dermatitis. The overgrowth of S. aureus can aggravate inflammatory reactions in AD. S. epidermidis, although another predominant bacterium in AD, exerts an immunoprotective role by regulating skin barrier?associated immunoreactions through the dendritic cells, interleukin (IL)?17A?producing Th17 cells/IL?17 pathway, and by suppressing the overgrowth of S. aureus. Malassezia can induce and aggravate inflammatory reactions in AD through colonization, sensitization, cross reactions, and other mechanisms. Studies on skin probiotics may provide new directions for the treatment of AD.
