Objective To investigate the relationship between plasma D-lactate levels and prognosis in newborns with neonatal necrotizing enterocolitis (NEC).Methods One hundred and four premature infants with NEC (stase Ⅱ and Ⅲ ) and another 104 premature infants without NEC admitted into Quanzhou Children's Hospital for other diseases from January 2007 to October 2010 were selected into this case control study.The gestational age,gender and birth weight of patients in the two groups were matched.NEC patients' bloods were collected within 24 hours after NEC was confirmed and blood samples of the control group were collected at the corresponding age.Enzymelinked immunosorbent assay was used to detect the plasma D-lactate level.Receiver operating characteristic curve was used to confirm the criteria of D-lactate positive,according to which,the NEC group was divided into high D-lactate group and normal D-lactate group,and the mortality and complication rate of the two groups were compared with x2 test.And NEC group was subdivided into death group and survive group according to the prognosis of the patients,and the difference of D-lactate level between the two groups were compared with t test.Results Among the NEC group,there were 63 cases (60.6％) of stage Ⅱ and 41 (39.4％) cases of stage Ⅲ ; 88 (84.6％) survived infants and 16 (15.4％) dead infants.D-lactate level was (35.4 ± 29.1) μg /ml in stage Ⅲ NEC group,(29.5±16.2) μg/ml in stage Ⅱ NEC group and (3.7±18.4) μg/ml in control group; there were statistical differences between each other(F=5.97,P＜0.05).Receiver operating characteristic curve analysis showed that if 6 μg/ml was set as the borderline,there were 87 cases(83.7％,87/104) with high D-lactate patients in NEC group,whose neonatal critical illness scoring (NCIS) was 80.9±22.6,significantly lower than that of normal D-lactate patients ( 95.8 ± 20.5) (t =2.417,P＜ 0.05),and higher neonatal septicemia rate (48.3％,42/87) and mortality (27.6％,24/87) compared with those [(5.9％,1/17) and (5.9％,1/17)] of normal D-lactate patients(x2 =11.539 and 7.146,P＜0.05,respectively).In NEC group,compared with the survived infants,the D-lactate level [(43.2±13.5) μg/ml vs (21.9 ± 22.9) μg/ml,t =4.572,P＜0.05] and the rate of septicemia [68.8％ (11/16) vs 38.6％ (34/88),x2 =3.445,P＜0.05] were higher in dead patients,and NCIS (82.4± 29.1 vs 90.6 ± 21.3,t =2.409,P＜0.05) was lower.Conctusions The level of plasma D-lactate related to the prognosis of neonatal NEC and which might be a good indicator for its prognosis and severity.

Objective To observe the effect of catgut implantation at acupoint on treating cerebrovascular epilepsy and discuss the therapeutic mechanism. Methods 58 patients were divided into an observation group and a control group. The control group was treated with sodium valproate, and the observation group was treated with catgut implantation at acupoint on the basis of the control group.Epilepsy scoring, sodium valproate adverse reactions, the change of blood concentrations of sodium valproate and curative effect evaluation and so on were observed before and after the treatment. Results The basic control and excellent rate in the observation group were 16.7%and 73.3%, better than the control group of 10.7%and 53.6% respectively. The epilepsy scoring and sodium valproate adverse reactions after treatment in the observation group were superior to the control group [observation group is(5.05±1.5),(5.09±1.53),control group is(6.40±1.74),(10.85±1.91),P<0.05]. The number of patients with blood concentrations of sodium valproate in range 50-100 mg/L after treatment was increased in the observation group(Z=2.07, P=0.038). Conclusion Catgut implantation at acupoint combined sodium valproate was more effective than sodium valproate in treating cerebrovascular epilepsy, which can obviously alleviate the adverse reaction of drugs and increase blood concentrations of sodium valproate.

Objective To observe the effects of low frequency electrical stimulation (LFES) on the proliferation of endogenous brain neural stem cells (NSCs) and on the expression of basic fibroblast growth factor (bFGF)and epidermal growth factor (EGF) in rats with acute cerebral infarction; to explore the therapeutic mechanism of LFES in improving neural function. Methods Fifty-four rats were randomly divided into a LFES group, a placebo stimulation group and a sham-operated group. Each group was further divided into 3rd day, 7th day and 14th day subgroups, with 6 rats in each subgroup. An acute cerebral infarction model was induced in the rats of the LFES and placebo stimulation groups by middle cerebral artery occlusion (MCAO). Three days after the operation, rats in the LFES group began LFES treatment (frequency 30 Hz, pulse width 250 μs, current intensity 3 mA, 10 min/d) ,while the placebo stimulation group was treated identically but without electricity. The rats in the sham-operated group had no special treatment. The expression of nestin positive cells in the subgranular zone of the hippocampus and the subventricular zone was detected by immunohistochemical staining. The expression of bFGF, EGF proteins and mRNA in the ischemic hemisphere was detected by Western blotting and RT-PCR analysis. A screen test was applied to evaluate motor function. Results Nestin-positive cells in the subgranular and subventricular zones of rats in the LFES group increased significantly more than in the placebo stimulation group at the 7th and 14th day. The expression of bFGF, EGF proteins and mRNA in the ischemic hemisphere was up-regulated compared to the placebo stimulation group at the 7th and 14th day. At the 14th day a difference in motor function was observed in rats in the LFES group compared with the placebo stimulation group. Conclusion LFES can promote the proliferation of endogenous brain NSCs and the expression of bFGF and EGF in rats with acute cerebral infarction. It can also improve motor function and enhance neural plasticity in the brain.

AIM: To observe the growthinhibiting cell cycle-modifying and apoptosis-inducing effects of satraplatin on human ovarian carcinoma cell line A2780, and to explore its possible mechanism. METHODS: The effect of satraplatin on A2780 cells proliferation was determined using MTT, and the change in cell cycle was analyzed using PI staining. Morphologic change was visualized by fluorescence and electron microscopy. AnnexinV-FITC/PI staining multiparameter flow cytometry and immuno- histochemical TUNEL assay were used to detect apoptotic cells. The activity of caspase-3 and the effect of pan-caspase inhibitor on cell viability were measured as well. RESULTS: The growthinhibiting and apoptosis-inducing effects of satraplatin were dose-dependent and similar to those of cisplatin. Satraplatin mainly caused A2780 cell accumulation in S phase accompanied by minor accumulation in G2/M phase. Cells treated with satraplatin exhibited typical morphology of apoptosis. Satraplatin-induced increase in caspase-3 activity of A2780 cells was concentration-dependent. The viability of A2780 cells was affected by pan-caspase inhibitor z-VAD-fmk in a dose-dependent manner under certain concentration of z-VAD-fmk. CONCLUSION: Satraplatin-induced apoptosis in A2780 in vitro was observed. Caspase-dependent and independent pathways were involved in apoptosis induced by satraplatin, and the latter included caspase-3 dependent and non-caspase-3 dependent pathways.

Objective:To explore the significance of detecting serum CRP,myocardial enzymes,liver function index in pediatric patients with rotavirus infectious diarrhea.Methods:110 pediatric patients with rotavirus infectious diarrhea and 85 age-matched patients with bacterial infectious diarrhea who were both treated in our hospital from January,2014 to May,2016 were enrolled in the present study.Another 20 healthy patients who had physical examination in our hospital were considered as control group.The differences of serum CRP,IL-6,hs-cTnT,CK,CL-MB,AST,ALT level and the incidence of parenteral injury were compared.Results:The incidence rate of lower respiratory tract infectivity,rash,myocardial damage and hepatic injury in RV group were significantly lower than the bacterial infectious group (P＜0.05),the level of serum CRP,IL-6 in RV group and bacterial infectious group were significantly higher than the control group,and those of RV group were significantly lower than bacterial infectious group (P ＜0.05);the level of hs-cTnT,CK,CL-MB,AST,ALT in RV group were significantly higher than bacterial infectious group and control group (P＜0.05),and those indexes of bacterial infectious group were no significantly differences compared with healthy control (P ＞ 0.05).Conclusion:The combined detection of serum CRP,myocardial enzyme and liver function indexes were of certain significance in the early distinguishing diagnosis of bacterial infectious diarrhea from rotavirus infectious diarrhea.
