Objective To investigate the clinical efficacy of acupoint application in treating senile hypertension of yin deficiency and yang excess type.Methods Sixty-six old patients with hypertension of yin deficiency and yang excess type were randomly allocated to treatment and control groups, 33 cases each. The control group took nifedipine controlled release tablets and the treatment group received acupoint application in addition. The quality of life score was recorded in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results The total efficacy rate in reducing blood pressure was 90.0% in the treatment group and 84.8% in the control group; there was no statistically significant difference between the two groups (P>0.05). The total efficacy rate in improving the symptoms was 90.9% in the treatment group and 69.7% in the control group; there was a statistically significant difference between the two groups (P<0.05). There was a statistically significant pre-/post-treatment difference in the quality of life score in the two groups (P<0.05). There was a statistically significant post-treatment difference in the quality of life score between the treatment and control groups (P<0.05).Conclusions Acupoint application is an effective way to treat senile hypertension of yin deficiency and yang excess type. It can improve the quality of life in the patients.

Objective To compare the effects of sedation induced with dexmedetomidine and propofol on intracranial pressure and cerebral oxygen metabolism in patients with permissive hypercapnia. Methods Twentyfour patients with acute respiratory distress syndrome (ARDS) were randomly divided into 2 groups ( n = 12 each) :dexmedetomidine group (group D) and propofol group (group P) . Their APACHE Ⅱ scores were 11-18. The patients were mechanically ventilated (VT 5-7 ml/kg, RR 12-17 bpm, PEEP 6-10 cm H2O, FiO2 40-60%). PaCO2 was maintained at 50-65 mm Hg. Radial artery was cannulated for direct BP monitoring and blood sampling. Right internal jugular vein was cannulated and the catheter was advanced cephalad until jugular bulb. Continuous infusion of dexmedetomidine was started at 0.5 μg· kg-1· h-1 and TCI of propofol was started at target plasma concentration (Cp) of 0.4 μg/ml. The infusion of both drugs was gradually increased until Ramsay score (1= fully awake, 6 =asleep, unresponsive to loud verbal stimulus) reached 3,4,5. Transcranial Doppler monitoring was used to determine cerebral blood flow velocity (CBFV), pulsatility index (PI) and resistance index (RI) before administration of dexmedetomidine and propofol (T0 ) and at 30 min after the 3 levels of sedation were reached (T1-3) . Meanwhile blood samples were taken from radial artery and jugular bulb for blood gas analyses. Cerebral O2 metabolic rate (CMRO2), cerebral A-V O2 content differences (Da-jvO2) and cerebral O2 extraction rate (CERO2) were calculated .ResultsCBFV, PI, RI and CMRO2 were significantly decreased at T1-3 as compared with the baseline values at T0 in both groups. CBFV was positively correlated with CMRO2 in both group D (r = 0.80) and group P ( r = 0.76) . CBFV, PI and RI were significantly lower at T1-3 in group D than in group P. There was no significant change in Da-jvO2 and CERO2 at T1-3 as compared with the baseline values at T0 in both groups. Conclusion At different sedation levels, dexmedetomidine results in lower intracranial pressure than propofol and maintains the balance between cerebral O2 supply and demand in patients with permissive hypercapnia.

Three-dimensional (3D) fluorescence spectra and thin layer fluorescence chromatogram of common Camptotheca fruit (CCF) crude drug, camptothecin (CPT) and 10-hydroxycamptothecin (HCPT) have been studied, and a novel fluorimetric method for determination of CPT in CCF crude drug has been established. In 3D fluorescence spectra, CPT presented 3 fluorescence peaks with excitation wavelengths lambdaex of 215, 255 and 365 nm, separately, and all peaks with emission wavelength lambdaem of 430 nm. HCPT presented 4 fluorescence peaks with lambdaex of 220, 265, 325 and 375 nm, separately, and all peaks with lambdaem of 555 nm. The fluorescence of CPT is much stronger than that of HCPT. Comparison of 3D fluorescence spectra and analysis of thin layer fluorescence chromatogram revealed that the main fluorescent component of CCF is CPT. HCPT and other components basically do not interfere with the fluorescence of CPT. Under the condition of pH 3.0-6.7, CCF aqueous solution can produce strong and steady fluorescence. Using methanol as solvent, the extracting solution of CCF was prepared, and diluted properly with water, then measured fluorescence intensity at lambdaex/lambdaem = 365/430 nm to determine the content of CPT. A linear calibration curve covered the concentration range 0.002 35-0.235 microg x mL(-1). The regression equation was IF = 9 + 30,844 c, with correlation coefficient r = 0.999 (n=9). The method has been applied to the analysis of CPT in a CCF sample, with a result of 0.127% and a spiked recovery rate of 102%. The reliability of the method has been verified by a thin layer chromatography-fluorescence scanning method. Experimental results demonstrated that this method can be used for quality evaluation of CCF crude drug.

Respiratory failure and respiratory complication are most reasons that result in death of ALS patients.Respiratory support,especially non-invasive Bi-level positive airway pressure,may improve living quality and prolong survival time.Treatment of respiratory support was gradually accepted and focused in the worldwide.In addition,malnutrition is an independent poor prognostic factor for ALS.Percutaneous endoscopic gastrostomy can ensure enough energy intake,improve nutritional status and prolong survival time.The profit and indication of BiPAP and PEG were Summarized.

Aim To study the role of nitric oxide by measuring the expression and activity of nitric oxide synthase in hippocampus of rats tolerance and dependence to the anticonvulsant action of flurazepam.Method Animal models of toleran and dependence to flurazepam were established. Nitric oxide synthase in hippocampus was measured using Western blot and immunohistochemistry, and its activity was evaluated using colorimetry. Result Hippocampal nNOS increased in rats tolerance to flurazepam. In rats dependence to flurazepam, hippocampal nNOS increased but without statistical significance. Total NOS activity increased dramatically both in flurazepam tolerane and dependene rats.Conclusion NO may play a role in rats tolerance and dependence to the anticonvulsant action of flurazepam.

Objective To explore the effect of psychological intervention combined with drug multimodal therapy on orthopedic analgesia and its effect on stress response, and to provide reference for clinical application.Methods 88 cases treated with open reduction and internal fixation for lower limb fracture as the object of study were collected from March 2015 to March 2017 in Baoji traditional Chinese medicine hospital, which were received multi-mode drug treatment.According to whether to receive psychological intervention, 88cases were divided into the intervention group(45 cases) and the control group(43 cases).Postoperative pain was assessed by visual analogue scale(VAS) and simplified McGill questionnaire(SF-MPQ), the changes of plasma CRP and IL-6 levels were compared before and after operation.Results There was no significant difference in VAS score, SF-MPQ score, preoperative plasma CRP and IL-6 levels between the two groups.One and 24 hour after operation, VAS score and SF-MPQ score were higher than those at admission(P<0.05).The VAS score and SF-MPQ score in the intervention group were lower than those in the control group at different time points(P<0.05).One and 24 hour after operation, plasma CRP and IL-6 levels in the two groups were significantly higher than those before operation(P<0.05), the levels of plasma CRP and IL-6 in the intervention group were significantly lower than those in the control group(P<0.05).Conclusion Psychological intervention combined with multimodal drug therapy can effectively reduce the degree of postoperative pain and stress reaction, and is conducive to postoperative rehabilitation.
