OBJECTIVE:To explore the effect of health intervention on blood pressure,medication compliance and the quali-ty of life in elderly patients with hypertension. METHODS:64 elderly patients with hypertension were selected and randomly divid-ed into observation group and control group,with 32 cases in each group. Both groups were given Amlodipine besylate tablet 5 mg,qd. Control group received routine hypertension knowledge education and regular recheck by guidance. Observation group addi-tionally received health intervention on the basis of control group. The blood pressure control,cognitive level of patients to hyper-tension,medication compliance,the level of trust in physicians and quality score of life were compared between 2 groups before and after intervention. RESULTS:There was no statistical significance in systolic blood pressure and diastolic blood pressure be-tween 2 groups before intervention (P>0.05). After intervention,systolic blood pressure and diastolic blood pressure of 2 groups were decreased significantly,and the observation group was significantly lower than the control group,with statistical significance (P<0.05). There was no statistical significance in cognitive level of patients to hypertension,medication compliance,the level of trust in physicians and quality score of life between 2 groups before intervention (P>0.05). After intervention,the observation group was better than the control group in terms of cognitive level of patients to hypertension,medication compliance,the level of trust in physicians and quality score of life,with statistical significance(P<0.05). CONCLUSIONS:Health intervention can effec-tively improve the cognitive level of elderly patients with hypertension to hypertension,improve the medication compliance and the level of trust in physicians,control blood pressure and improve the quality of life.

BACKGROUND: The neurological basis for learning and memory is the high plasticity of central nervous system, and special rehabilitative training is necessary in the process of the functional recombination of central nervous system.OBJECTIVE: To observe the capability of rehabilitative training in differentiating learning ability and memory maintaining of one-trial passive avoidance response, and its correlation with the kinetic properties of Nmethyl-D-aspartic acid (NMDA) receptor channel of contralateral hippocampal neuron in rats with cerebral infarction.DESIGN: A randomized control animal trial.SETTING: Department of Rehabilitative Medicine, Affiliated Hospital of Luzhou Medical College.MATERIALS: The experiment was carried out in the central laboratory of Luzhou Medical College between March 2000 and February 2002. Twentyfour male Wistar rats were randomly divided into three groups with 8 rats in each: free movement after cerebral infarction group (model group), rehabilitative training after cerebral infarction group (rehabilitation group) and normal group.METHODS: ① Model establishment: Rats in the model group and rehabilitation group were made into models of infarction of right middle cerebral artery, and those in the normal group were not given any treatment. ②Rehabilitative training: After 4 days, only the rats in the rehabilitation group were trained with rolling-cage exerciser, screen exerciser and balance exerciser for 4 weeks. ③ Learning and memory tests: The learning and memory performances of all the rats were tested at 35 days postoperatively. The Y-maze test was applied to mainly observe the needed number f training for the rats to reach 9/10 correct response (for running to dark arm), and the multi-functional conditioned reflex box to observe the stayed duration on the diving board (step-through latency). ④ The single channel current property of NMDA receptor in hippocampal neurons was recorded with cell adhesion after learning and memory tests.MAIN OUTCOME MEASURES: ① training times needed for the rats to grasp the structure of the maze in each group; ② step-through latency in each group; ③ single channel current property of NMDA receptor in each group.RESULTS: All the 24 rats were involved in the analysis of results. ① The training times needed for the rats to grasp the structure of the maze in the rehabilitation group and normal group were significantly different from that in the model group [(68.02±11.67), (57.62±10.31), (107.07±16.32) times, P ＜0.05], and there was no significant difference between the rehabilitation group and normal group (P＞0.05). ② The medians of step-through latency before shock in the rehabilitation group and normal group were significantly different from that in the model group (286.7 s, 298.4 s, 126.7 s, P ＞0.05), and there was no significant difference between the rehabilitation group and normal group (P＞0.05). ③ The 35 pS short open NMDA receptor channel mainly existed in the hippocampal neurons of rats in the rehabilitation group, the open proportion was 0.099±0.007. The duration and proportion of 20 pS short and long open and the 35 pS short open NMDA receptor channels in the hippocampal neurons of rats were not significantly different from those in the normal group (P＞0.05). In the model group, 20 pS open channel was mainly observed, and the durations of 20 pS short and long open channels were obviously shorter than those in the rehabilitation group, the open proportion of 35 pS short open channel was 0.036t0.04, which was lower than that in the rehabilitation group,but no 35 pS long open channel was observed.CONCLUSION: Rehabilitative training accelerates the recovery of the learning and memory abilities of rats with cerebral infarction by changing the NMDA receptor channel properties of contralateral hippocampal neurons.

Objective To observe the effect of neuropeptide Y(NPY) on the levels of serum interleukins(ILs)in guinea pigs with experimental allergic encephalomyelitis(EAE).Methods 30 guinea pigs were divided randomly into normol control group,EAE group and NPY group.The NPY was injected into the intracerebroventricular in NPY group one week before the EAE model be made.The EAE molders were made by injecting the homogenate of rat's spinal cord into the plantar of guinea pigs in groups EAE and NPY.Then,the neurological deficits score was observed everyday,the incidence and the delitescence of EAE were observed too.The levels of serum IL-1?,IL-2,IL-4,IL-6 and IL-8 were detected,and the neuropathological examination was used when symotoms peak period of EAE models.Results(1)The incidences of the EAE in groups EAE and NPY were 100% and 90%,the delitescences of EAE were(10.0?4.8)d and(25.4?12.6)d,the neurological deficits scores at the symotoms peak period were(3.60?0.52) and(1.80?1.14),respectively.There were significantly differences between the two groups(all P

Objective To explore the effect of BCG-polysaccharide nucleic acid(BCG-PSN) on the numbers of Th3,Th2 and Th1 cells in peripheral blood mononuclear cell(PBMC) and airway inflammation status in patients with asthma.Methods Twenty-six patients with moderate persistent asthma were enrolled into the study and randomly divided into simple medication group(n=13,accepted Fluticasone/salmeterol alone) and combined medication group(n=13,accepted Fluticasone/salmeterol+BCG-PSN together).The numbers of Th3,Th1 and Th2 cells in PBMC, the serum levels of TGF-β,IFN-γ,IL-4 and IgE and the clinical effect and airway inflammation status were observed at three time points: before,1.5 months after and 3 months after treatment. Results (1)At 1.5 months after treatment,the Th1/Th2 number was significantly higher in the combined medication group than the simple medication group(1.20±0.57 vs 0.79±0.39,t= 2.129,P＜0.05),and the asthma control test scale(ACT) showed similar difference(18.31±1.75 vs.15.54±2.40,t=3.359,P＜0.01) between the two groups.(2)At 3 months after treatment,the Th1/Th2 number was significantly higher in the combined medication group than the simple medication group(1.73±0.74 vs1.16±0.48,t=2.327,P＜0.05),and the ACT also showed the same kind of difference(22.46±1.13 vs.20.23±2.59,t=2.851,P＜0.01) between the two groups.In addition,at this time point the PEF variability was significant lower in the combined medication group than the simple medication group([9.88±2.18]% vs.[12.05±2.74]%,t=2.235,P＜0.05).(3)We found no significant differences in the comparisons of the numbers of T helper cell subsets in PBMC ,the serum levels of cytokines and IgE,the numbers of inflammatory cells in induced sputum between the two groups(Ps＞0.05).(4)No correlation were found between Th3 cell numbers in PBMC and the serum levels of IgE in the two groups.Conclusion The combined use of Fluticasone/salmeterol and BCG-PSN can further correct the imbalance of Th1/Th2 cells,alleviate clinical symptom of asthma and airway hyper-responsiveness.The therapeutic efficacy improves along with the therapy period,better in the combined medication group than the simple medication group.BCG-PSN has no significant effects on the numbers of Th3 in PBMC in patients with asthma.

Objective To explore the expression of GATA-3 in pulmonary tissue of asthmatic mice and the inhibitory effect of dexamethsone(Dex)on it.Methods The Blab/c mice asthma model was induced by ovalbumin(OVA) with classic method.Twenty-four male mice were randomly divided into control group,asthmatic group and Dex treated group.The expression of GATA-3 protein was measured by immunohistochemical staining.The expression of GATA-3 mRNA was measured by reverse transcription-polymerase chain reaction(RT-PCR).The level of IL-4 in mice spleen CD4 T cell was measured by flow cytometry.The airway inflammation was evaluated by HE staining.Results The percentages of postive GATA-3,GATA-3 mRNA and IL-4 protein of asthmatic group were significantly higher than those of control group(P

Objective To explore the effects of hypoxia on expression of signal transduction and activators of transcription (STAT3) gene and proliferation of rat pulmonary arterial smooth muscle cells (PASMCs). Methods RT PCR and western blot were used to assess the levels of STAT3 mRNA and tyrosine phosphorylated STAT3 protein after primarily cultured rat PASMCs were exposed to hypoxia for 2h, 6h, 12h, 24h respectively. 3 H TdR incorporation was used to observe the cell proliferation. Results The expression of STAT3 mRNA was increased after exposure of PASMCs to hypoxia for 2h, and peaked when exposed for 6h, then declined when exposed for 12h, but still higher than that in PASMCs when exposed to normal oxygentension. The level of tyrosine phosphorylated STAT3 was increased when exposed for 6h,peaked after 12h and delined after 24h in PASMCs exposed to hypoxia. With prolongation of time of hypoxia, 3 H TdR incorporation in PASMCs was significantly higher, and reached a maximum after 24h. Conclusion The results suggested that hypoxia could induce the expression of STAT3 mRNA and activation of STAT3 protein in PASMCs, implying that STAT3 gene might play an important role in the early stage of hypoxia induced PASMCs proliferation

Objective To compare the effects of four different analgesia techniques on serum IL-6, IL-10 and heat shock protein 70 (HSP70) in patients after hysterectomy. Methods Forty-eight ASA Ⅰ-Ⅱ patients aged 32-54 yrs weighing 45-79 kg after hysterectomy were randomly divided into 4 groups ( n = 12 each): group Ⅰ received patient-controlled epidural analgesia (PCEA) with 0.2% ropivacaine + fentanyl 2 ?g?ml-1 + 0.008% ondansetron; group Ⅱ received patient-controlled intravenous analgesia (PCIA) with fentanyl 8 ?g?ml-1 + 0.008% ondansetron; group Ⅲ PCEA with 0.2% ropivacaine + tramadol 2 mg?ml-1 +0.008% ondansetron and group Ⅳ PCI A with tramadol 8 mg?ml-1 + 0.008% ondansetron. Both PCEA and PCIA were commenced with a loading dose of 5 ml. The PCA pump was set up with an 1 ml bolus with a 10 min lockout interval and a background infusion at 1 ml?h-1. Blood samples were taken before anesthesia (baseline) and at 2, 24, 48 and 72 h after surgery for determination of serum levels of IL-6, IL-10 and HSP 70.Results The changes in serum IL-6, IL-10 and HSP 70 concentrations were similar. Serum IL-6, IL-10 and HSP 70 levels were all increased after surgery in the 4 groups, and they reached a peak at 24 h after surgery. Serum IL-6 and HSP 70 levels at 24h after surgery were significantly lower in group Ⅰ and Ⅲ than in group Ⅱ and Ⅳ( P
