Objective To evaluate the prognostic values of leukocyte count,hemoglobin,biochemical parameters,erythrocyte sedimentation rate and immunoglobulin on mortality in patients aged 80 years and over.Methods Totally 342 patients(aged 85.6±4.0 years)were followed up for (82.0±36.9) months,and the cause and time of death were recorded.Results During the period of follow up,198 patients suffered from death.Compared with the survival group (132 cases),the death group had older age [ (86.5±4.4)years vs.(84.5±3.2)years,t=-4.86,P＜0.01 ],higher white blood cell [ (6.2± 1.7) ＞ 109/L vs.(5.5±1.3) × 109/L,t=-3.93,P＜0.01 ],lower hemoglobin [(134.4±14.4)g/L vs.(140.0± 12.6)g/L,t= 3.65,P＜0.01 ],slightly faster erythrocyte sedimentation rate [ 11 mm/h(15 mm/h) vs.9 mm/h (10 mm/h),U=- 3.31,P＜0.01 ],lower immunoglobulin M [ (0.9±0.5)mg/L vs.(1.1±0.8)mg/L,t =2.55,P＜0.05 ],slightly higher urea nitrogen [ (7.5±2.6) mmol/L vs.(6.8±1.6) mmol/L,t=2.81,P＜0.01]and creatinine [(113.0±32.5) μmol/L vs.(100.5±15.8) μmol/L,t=-4.65,P＜0.01 ].Cox multivariate analysis revealed that older age (RR=1.083,95％CI:1.040 1.127,P＜0.01),white blood cell count (RR=1.134,95％CI:1.021-1.260,P＜0.05),creatinine (RR=1.011,95％CI=1.0021.020,P＜0.05),hemoglobin(RR=0.835,95％CI:0.714-0.975,P＜0.05)andimmunoglobulin M(RR=0.710,95％CI:0.521-0.966,P＜0.03),aorticaneurysm(RR=2.144,95％CI:1.163-3.951,P ＜ 0.05 ) were the independent risk factors for death.Conclusions Aging,increased WBC count,decreased hemoglobin and immunoglobulin M,elevated creatinine and aortic aneurysm are the independent risk factors for death,which are powerful parameters for the prognostic evaluation in the elderly aged 80 years and over.

OBJECTIVETo explore the auricular point specificity of the electric determination in stroke so as to provide the evidence for the objective study on the auricular point diagnosis in stroke.

METHODSThirty patients of stroke were selected in an observation group; 30 patients of non-stroke internal medicine disorder were in a control group A; 30 persons of healthy examination were in a control group B. In the observation group.and the control group A, beside the conventional treatment, acupuncture was applied to all the cases. In the observation group, Jianyu (LI 15), Quchi (LI 11), Shousanili (LI 10), Hegu (LI 4), Waiguan (TE 5), Liangqiu (ST 34), Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3) were selected on the affected side. In the control group A, Yin-tang (GV 29), Baihui (GV 20), Sishencong (EX-HN 1), Fengfu (GV 16), Dazhui (GV 14), Fengchi (GB 20), Tianzhu (BL 10), Jiaji (EX-B 2) C4-C7 were selected. Acupuncture was given once a day in the two groups. The; treatment of one week made one session, and continuously 2 sessions were required. In the control group B, the convention physical examination was provided without any medication and acupuncture involved. The CLRH-A auricular point detector was used to detect the entire auricular point area in the subjects and the positive reaction sites of auricular points in the subjects of each group before and after treatment separately. The auricular point positive detecting score and positive point frequency were observed in the subjects.

RESULTSBefore treatment, the auricular points detecting score in the observation group was obviously higher than that in the control group A and control group B (both P<0. 05). The difference in the score between the control groups was not significant in' comparison (P>0. 05). In two weeks of treatment, the auricular points detecting score in the observation group was reduced apparently (P<0. 05). The difference was not significant before and after treatment in either the control grolip A or the control group B (both P>0.05). In the observation group, the first 15 points with high frequencies of positive reaction were naogan (AT3,4i), pizhixia (AT4), e (AT1), xin (CO15), gan (CO12), nie (AT2), zhen (AT3), shen (CO10), jiaogan (AH6a), pi (CO13) shenmen (TF4), wei (CO4), neifenmi (CO18), shenshangxian (TG2p) and erjian (HX6,7i). The differences were significant in the frequencies of positive reaction at 9 auricular points as compared with the control group A and the control group B respectively, named naogan (AT3,4i), pizhixia (AT4), e (AT1), xin (CO15), gan (CO12), nie (AT2), zhen (AT3), shen (CO10) and jiaogan (AH6a) (all P <0. 05).

CONCLUSIONThe pathological degree of positive reaction about auricular points in stroke patients is higher than those in the patients of non-stroke internal medicine disease and the healthy people. It is verified that the auricular diagnostic method is specific in stroke. naogan (AT3,4i), pizhixia (AT4), e (AT1), xin (C15), gan (GO12), nie (AT2), zhen (AT3), shen (CO10) and jiaogan (AH6a) are correlative with stroke.

The mechanism of Tongmai Oral Liquid (TOL) for chronic nephritis rat model with Qi-deficiency and blood-stasis syndrome was studied.The model was established by adding Qi-deficiency and blood-stasis syndrome to the chronic nephritis rats. The experimental rats were randomly allocated to 5 groups: Group A (treated with high dosage of TOL), Group B (treated with low dosage of TOL), Group C (treated with Jinshuibao), Group D (model control group) and Group E (normal control group). After 4 weeks of treatment, general health state, biochemical indexes including T lymphocyte subgroup and blood rheology, and pathological damage of kidney tissue were much improved in Group A than Group B and Group C. It is indicated that TOL can improve the renal function and delay the occurrence of glomerular arteriosclerosis in rats by reinforcing Qi, activating blood flow, regulating immune function, lessening the hypercoagulative state and reducing renal damage.

Objective To investigate effects of different doses of recombinant human bone morphogenetic protein-2 (rhBMP-2) on vascular endothelial growth factor (VEGF) expression in fetal mouse osteoblasts.Methods Calvaria osteoblasts of fetal mice of 19 days were cultured.The effects of rhBMP-2 at different doses and different action times on VEGF expression patterns in fetal mouse osteoblasts were observed with reverse transcrip- tion-polymerase chain reaction (RT-PCR) and Western blot staining.Results In the present study,RT-PCR detected a steady expression of VEGF mRNA in the control fetal mouse osteoblasts.The levels of VEGF mRNA increased in an apparent biphasic manner with a maximum stimulation (about 2-fold above the control,P＜0.05 ) in both VEGF mRNA species observed at 300 ng/mL of rbBMP-2.After 48 h of rhBMP-2 treatment,the VEGF mRNA levels approached those in the control.The VEGF mRNA levels appeared to be biphasic in rhBMP-2-treated cultures,showing peak induction at 3 and 24 h and remaining elevated at 48 b.Compared with the individual control value at each time point,an apparent maximum increase (about 2.5-fold above the control,P＜0.05) occurred at 6 h.The second peak induction,about 2-fold above that in the control,occurred at about 36 h.Conclusions The expression of VEGF mRNA is steady in the control fetal mouse osteoblasts.RhBMP-2 can promote the expression of VEGF in dose-dependent and time-dependent manners.

Aim To study the effect of Baoxinbao film on endothelin(ET) and nitric oxide(NO) secretion in patients with stable angina pectoris(SAP).Methods 76 patients with SAP were randomly divided into two groups, with 40 cases in the baoxinbao group plastered with baoxinbao film and 36 cases in the isosorbide dinitrate group receiving isosorbide dinitrate. The levels of plasma ET and NO before and after treatment were observed. Results The concentrations of plasma ET were increased and plasma NO reduced significantly in the SAP patients respectively, as compared with those in the control group(all P

it was 4% (3/75). GP73-positive rate in HCC was higher than that of the normal liver tissues (χ2=73.60, P<0.05). sCLU-positive rate in HCC was also higher than that of the normal liver tissues (χ2=207.94, P<0.05). GP73 expression was positively correlated with sCLU expression in HCC (r=0.405, P<0.05). GP73 and sCLU were associated with clinicopathological features including tumor differentiation, TNM stage and vascular invasion (P<0.05); GP73 and sCLU had no correlation with the patient’s gender, age, HBsAg, cirrhosis, AFP value, portal vein thrombosis and tumor numbers (P>0.05). GP73 was associated with survival but not sCLU. Conclusion:GP73 and sCLU have higher positive rates in HCC and GP73 is positively correlated with sCLU. The expression of GP73 and sCLU are probably closely related with the invasion of HCC, which can help evaluate the prognosis of the patients.

Objective To analyze the clinical features and the effect of therapy on cutaneous emphysema of chest wall and/or pneumomediastinum complicated in severe acute triphosgene poisoning patients.Methods Among 81 triphosgene poisoning patients,5 complicated with cutaneousemphysema of chest wall and/or pneumomediastinum were analyzed in respect of the clinical data including age,gender,arterial blood gas (ABG),modes of mechanical ventilation support and so on.Results Five patients consisting of 3 males and 2 females,aged (23.20 ± 5.17) years,were complicated with cutaneous emphysema of chest wall and/or pneumomediastium with a prevalence rate of 0.06％.Of them,4 were alleviated completely and 1 died of acute respiratory distress syndrome (ARDS).There was no significant difference in arterial blood gas analysis (ABG) between patients with cutaneousemphysema and/or pneumomediastinum and patients without ( P ＞ 0.05 ).Conclusions Triphosgene-induced acute lung injury treated with mechanical ventilation support with high PEEP is highly suggested as high risk factor for the formation of cutaneous emphysema of chest wall and/or pneumomediastinum in severe acute Triphosgene poisoning patients.It is very important to set the PEEP level of mechanical ventilation support as low as possible for avoidance of alveolar rupture.

Objective To observe the changes of serum soluble CD40 ligand (sCD40L) and fibrinogen in acute myocardial infarction (AMI) patients and to investigate the clinical predictive value of increased serum sCD40L and fibrinogen. Methods Serum sCD40L level of 60 AMI patients was determined by enzyme-linked im-munosorbent assay (ELISA). Plasma level of fibrinogen was measured. The patients were followed up for 2 years af-ter discharge from the hospital and were observed for cardiovascular event. Results AMI patients had higher sCD40L and fibrinogen levels than those of controls [(15.36±7.32) μg/L vs. (5.79±2.78) μg/L, (4.60±1.37)g/L vs. (3.03±0.82) g/L,P<0.001] ,which were significantly higher in the patients experiencing cardio-vascular event than those without cardiovascular event [(18.14±6.34) μg/L vs. (14.38±6.67) μg/L and (4.97±1.33)g/L vs. (4.20±1.24} g/L] (P<0.05). The patients with sCD40L≥14.5 μg/L or fibrinogen≥ 4.4 g/L experienced increased risk of adverse cardiovascular events (P<0.05). In AMI patients, sCD40L level was significantly higher in patients with diabetes than in nondiabetics [(18.38±6.71) μg/L vs. (14.46±6.48) μg/L, P<0.05)]. Fibrinogen level was related to sCD40L (r=0.27, P<0.05) and LVEF(r=-0.319, P<0.05). Conclusion Increased sCD40L and fibrinogen levels,which maybe related to the pathogenesis of AMI,can be found in AMI patients and can indicate an independent increased risk of major adverse cardiovascular events. Diabetes is independently associated with elevated sCD40L level in AMI patients.

Objective: To construct the expression plasmid of a novel gene human NBEAL1 (neurobeachin like 1), and to study its relationship with the pathological grades of glioma. Methods: Total RNA of human glioma cell line U251 was extracted. NBEAL1 expression plasmid pGEX-KG/NBEAL1 was constructed and transferred into E. coli BL21. Recombinant NBEAL1 protein was induced by IPTG and further purified by GST affinity chromatographic column. The purity of recombinant NBEAL1 protein was examined by Western blotting analysis. A NBEAL1 protein specific monoclonal antibody was prepared and was used to study the relationship of NBEAL1 expression with pathological grades of glioma. Results: The NBEAL1 gene fragment was successfully cloned into pGEX-KG expression plasmid and verified by DNA sequencing. The recombinant NBEAL1 protein was expressed in inclusion bodies, with a yield of more than 30% of total bacterial proteins; the purity of purified NBEAL1 protein was above 95%. Western blotting analysis confirmed that the purified protein containing GST tag and NBEAL protein. NBEAL1 protein was lowly expressed in normal brain tissues and highly expressed in low grade glioma tissues; and the expression of NBEAL1 decreased with the increase of glioma malignancy. Conclusion: The NBEAL1 protein has been successfully cloned, expressed and purified. NBEAL1 protein expression in glioma tissues is negatively associated with the pathological grades of glioma.
