Objective To study the effect of local mild hypothermia on serum brain natriuretic peptide (BNP) in patients with acute intracerebral hemorrhage.Methods Sixty patients with acute intracerebral hemorrhage were divided into local mild hypothermia group (30 cases) and routine therapy group (30 cases) by random digits table method.Routine therapy group was given conventional therapy,and local mild hypothermia group was given local mild hypothermia treatment besides conventional therapy.The neurologic impairment was evaluated according to American National Institute of Health Stroke Scale (NIHSS) scores on admission,and on the 3rd,7th and 14th day after treatment.Serum BNP levels in patients were determined dynamically on admission,and on the 3rd and 14th day after treatment.The effect was evaluated on the 14th day after treatment.Results There was no significant difference in serum BNP on admission between two groups (P ＞ 0.05).Serum BNP on the 3rd,14th day after treatment in local mild hypothermia group was lower than that in routine therapy group[(153.47 ± 32.01) ng/L vs.(187.45 ± 40.21)ng/L and (111.02 ± 38.27) ng/L vs.(139.71 ± 29.53) ng/L],and there was significant difference(P ＜ 0.01 or ＜ 0.05).There was no significant difference in NIHSS scores on admission and on the 3rd day after treatment between two groups (P ＞0.05).NIHSS scores on the 7th and 14th day after treatment in local mild hypothermia group was lower than that in routine therapy group [(13.84 ± 6.00) scores vs.(16.59 ± 4.62)scores and (9.23 ± 4.48) scores vs.(13.02 ± 6.76) scores],and there was significant difference (P ＜ 0.01).The total effective power in local mild hypothermia group was higher than that in routine therapy group[90.0％(27/30) vs.66.7％ (20/30)],and there was significant difference (P ＜ 0.05).Conclusions The local mild hypothermia therapy can not only significantly improve the defect of nerve function in patients with acute intracerebral hemorrhage but also reduce the serum BNP.It can improve the curative effect in patients with acute intracerebral hemorrhage.

Objective To study the IgG antibodies on red cell surface in ABO and Rh-incompatible infants and to evaluate its predictive value for hemolysis. Methods From Nov. 2001 to Jul. 2002,50 full term newborn babies with ABO and Rh incompatibility hemolysis were admitted .They were divided into two groups according to the direct Coombs test(DCT): 38 cases with positive result and 12 cases were negative. Another 30 normal newborns were chosen as control group. Erythrocyte associated IgG,A and M were measured by a flow cytometry (FCM). Results the mean level of concentration of IgG antibodies in positive DCT group was (12.64?16.83)%,while (4.54?2.54)% in negative DCT group ( P 427.5 ?mol/L,IgG was elevated with the increased TSB level. There was a close relationship between the concentration of TSB and IgG ( r =0.678). Conclusion Measurement of erythrocyte surface antigen IgG assists the diagnosis of maternal-fetal incompatible hemolysis,especially when with a positive direct Coombs test result.

Objective To investigate the association of serum adiponectin and tumor necrosis factor alpha (TNF-α) with endothelial damages in metabolic syndrome (MS) patients. Methods One-hundred and five patients diagnosed as MS were recruited as cases and 37 subjects without characteristics of MS were recruited as controls. The cases were divided into two groups according to the level of serum von Willebrand factor (vWF) :normal endo-thelial functional MS group (57 patients) and abnormal endothelial functional MS group (48 patients). Serum adi-ponectin concentration was measured by enzyme-linked immanosorbont assay (ELISA). Serum TNF-α concentration was measured by radioimmunoassay (RIA). Results The concentration of serum adiponectin in normal subjects (10.5 mg/L [SD:3.2]) was significantly higher than both that of normal endothelial functional MS group (7.9 mg/L [SD :2.2]) and abnormal endothelial functional MS group (6.5 μg/L [SD :2.5]) (P < 0.05). The concen-tration of serum TNF-α in normal subjects(0.17 μg/L [SD :0.04]) were significantly lower than that of normal en-dothelial functional MS group (0.19 μg/L [SD:0.05]) and abnormal endothelial functional MS group (0.23 ng/mi [SD: 0.06]) (P< 0.05). The level of serum adiponectin were negatively correlated with TNF-α(r=- 0.555, P < 0.01). Logistic regression analysis results showed that high level of TNF-α was a risk factor of endo-thelial damages (OR = 20.649, P = 0.035), whereas high level of serum adiponectin protected against endothelial damages (OR = 0.340,P=0.006). Conclusions Low level of serum adiponectin and high level of serum TNF-α may correlate with endothelial damages in MS patients.

OBJECTIVETo explore the maintenance effects of acupoint catgut embedding at early time on gastrointestinal function in patients with craniocerebral injury.

METHODSSixty craniocerebral injury patients with 5 to 12 points of Glasgow coma scale (GCS), according to treatment order, were alternately divided into an observation group and a control group, 30 cases in each one. Patients in the control group were treated with regular treatment and nursing care. Based on this, patients in the observation group, according to different pathogenesis and symptoms presented within 24 h into hospitalization, were additionally treated with acupoint catgut embedding. The recovery time of borborygmus, time of first anal aerofluxus, time of first defecation, abdominal pressure at different time points, the occurrence rate of complications (upper gastrointestinal hemorrhage, diarrhea, vomiting), time of enteral nutrition tolerance rate reaching 30 kcal/kg x d were observed and recorded.

RESULTSThe recovery time of borborygmus, time of first anal aerofluxus, time of first defecation and time of enteral nutrition tolerance rate reaching 30 kcal/kg x d in the observation group were all earlier to those in the control group (all P<0.01). At 48 h, 4 d and 7 d into hospitalization, the abdominal pressures in the observation group were all lower than those in the control group [(11.10 +/- 1.47) mmHg vs. (13.50 +/- 1.43) mmHg, (8.40 +/- 1.25) mmHg vs. (11.90 +/- 1.56) mmHg, (6.73 +/- 0.74) mmHg vs. (10.80 +/- 1.30) mmHg, all P<0.01]. There were 8 cases with complications of gastrointestinal hemorrhage, diarrhea and vomiting in the observation group with the occurrence rate o 27% (8/30), which was lower than those in the control group (70.0% (21/30), P<0.01.

CONCLUSIONThe acupoint catgut embedding at early time in craniocerebral injury patients could improve the recovery of gastrointestinal function, reduce intolerance of enteral nutrition and occurrence rate of various complications.

Before and after treatment as well as before metastasis,the combined detection of progastrin-releasing peptide (ProGRP) and neuron-specific enolase (NSE) was performed in 150 patients with small cell lung cancer.The follow-up period was 1 year.Enzyme-linked immunosorbent assay (ELISA) and electrochemiluminescence immunoassay were conducted.The result showed a negative correlation between the serum levels of ProGRP and NSE the curative effect.And a positive correlation existed between the serum levels of ProGRP and NSE and disease development.The difference had statistical significance (P ＜ 0.05).The levels of ProGRP and NSE may be used to indicate the disease development and evaluate the curative effect.

Objective:To investigate the effect of PLTP gene on CSE-induced IL-8 production in human bronchial epithelial cell line (HBECs). Methods:Wistar rats were exposed to air or cigarette smoke for 6 hours/day on 3 consecutive days,then the lungs were sectioned and examined. The number of total white blood cell and differential white blood cells in BALF were counted. The different concentrations of CSE co-cultured with HBECs for 24 hours. Cells growth was detected by MTT assay. Expression levels of PLTP mRNA and IL-8 mRNA were examined by RT-PCR,protein of PLTP was investigated by Western blot,and production of IL-8 ex-amined by ELISA. Results:The number of white blood cells in BALF was significantly increased compared with controls. Enhanced ex-pression level of PLTP and IL-8 were observed in CS-exposure group. Proliferation of HBECs tends to decrease at high concentrations of CSE(2. 0% CSE and 4. 0% CSE). The results suggested that the production of IL-8 induced by CSE in a time- and concentration-dependent manner,while the expression of PLTP induced by CSE in a dose-dependent manner. Furthermore,expression levels of IL-8 significantly increased after silence PLTP gene. Conclusion:PLTP siRNA could increase CSE-induced IL-8 production in HBECs.

Objective To study the correlation of the serum levels of pro-gastrin-releasing peptide (ProGRP) and neuro-specific enolase (NSE) with different treatments in limited-disease small cell lung cancer (L-SCLC) patients.Methods 150 L-SCLC patients were randomly divided into three groups including concurrent chemo-radiotherapy group,sequential chemo-radiotherapy group,and chemotherapy group.The serum levels of ProGRP and NSE were detected by enzyme-linked immunosorbent assay (ELISA) and electrochemiluminescence immunoassay before and after different treatments.The follow-up phase was 12 months.Results The serum levels of ProGRP and NSE were significantly decreased in all 3 groups after treatment (318.96,250.77,226.18 pg/ml and 31.72,23.95,17.89 μg/L),and the lowest level was observed in concurrent chemo-radiotherapy group,then the sequential chemo-radiotherapy group and chemotherapy group.The short term therapeutic effects were in the same sequence,and there was statistical significance between concurrent chemoradiotherapy group and chemotherapy (P ＜ 0.05).The decrease extent of ProGRP and NSE in effective cases (CR+PR) was significantly higher than that in failure cases in all 3 groups.The serum levels of ProGRP and NSE were increased with disease progress (P ＜ 0.05).Conclusion The serum levels of ProGRP and NSE can be used to reflect the patient' s condition and evaluate therapeutic effect in L-SCLC.The concurrent chemo-radiotherapy is more effective than sequential chemo-radiotherapy and chemotherapy only in L-SCLC.
