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.

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.

Objective To study the correlation of perceived social support and job burnout with subjective well-being of male nurses.Methods 122 nurses were selected from three large hospitals of Yantai and Weihai region,including 61 male and 61 female nurses,perceived social support scale,job burnout scale and subjective well-being scale were used for investigation.The correlation of perceived social support and job burnout with subjective well-being of male nurses was analyzed.Results Male nurse' occupation self-efficacy score as well as perceived social support score were significantly lower than those of female nurses.The three dimensions of job burnout of male nurses were negatively correlated with subjective well-being and perceived social support,perceived social support and subjective well-being.Perceived social support was positively correlated with subjective well-being.Job burnout and perceived social support could predict subjective well-being.Conclusions The social support and job burnout have a large impact on subjective well-being of male nurses.

Vasovagal syncope (VVS) is the most common cause of transient loss of consciousness ( TLOC ),mainly with head-up tilt test (HUTT) for diagnosis and treatment evaluation.Beacause of potential risks in the process of HUTT,it is necessary to explore an early,accurate,safe,effective,inexpensive and convenient means of diagnosis and evaluation for VVS.The means of quantitative history are now in practice of clinical trials.The means commonly used are Calgary Presyncope Form (CPF)and three questionaires about point scores in the Calgary syncope symptom studies.Due to its stable,simple and easy to apply features,CPF has some advantages on assessing the effectiveness of different treatment methods for VVS.The three questionnaires have some application potential in diagnosis for VVS.

Objective:To develop a method for the determination of natural benzoic acid in Mesona chinensis Benth. with different production places and storage time. Methods:HPLC was adopted, the column was an Agilent ZORBAX SB-C18 (250 mm × 4. 6 mm, 5 μm) column, the mobile phase was methanol-0. 02 mol·L-1 ammonium acetate (5∶95) at the flow rate of 1. 0 ml·min-1 , the col-umn temperature was 35℃, the detection wavelength was 230 nm, and the injection vocume was 10μl.

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.

In the present paper,the authors make a summary about the development of acupuncture needles in Chinese ancient times recorded in the literature,and have a discussion on the effect of the thickness of acupuncture needles on clinical the-rapeutic efficacy in accordance with modern medical theories,the development of its clinical application and by combining their own experience in acupuncture practice. They conclude that the thickness of the abdominal needle is a negligible factor influencing the therapeutic efficacy of the reinforcing-reducing manipulations. In the treatment of deficiency pattern disorders,a thinner acupuncture needle is suitable,while for excess syndrome,a thicker acupuncture needle is recommended. In the light of the patient's constitution and different state of clinical conditions,a flexible application of the acupuncture needle with different diameters is highly recommended in clinical practice. In this way,the clinical therapeutic effect would be improved much.
