1.Pharmacokinetics of gastrodin from Tiangou Jiangya capsule in rats.
China Journal of Chinese Materia Medica 2014;39(15):2964-2967
The paper aims to study the pharmacokinetic parameters of gastrodin in rats effected by compound compatibilitiy and different doses of Tiangou Jiangya capsule. The extracts from Gastrodiae Rhizoma( equivalent to gastrodin 16.82 mg x kg(-1) and Tiangou jiangya capsule (equivalent to gastrodin 8.410, 16.82, 33.64 mg x kg(-1)) were oral administrated to rats respectively. The plasma were taken at various time points and treated with acetonitrile to measure the contents of gastrodin by HPLC method. The mean plasma concentration-time data were analyzed by 3P97 pharmacokinetic software and the pharmacokinetic parameters between groups were treated by SPSS 16.0. The results showed that gastrodin in rat was fitted to one-compartment model, Cmax and AUC of Tiangou Jiangya capsule were in direct proportion to oral administration, and t1/2Ka had nothing to do with doses, which indicated that gastrodin was fitted first-order rate transfter process in vivo. Morever, comparison with the Gastrodiae Rhizoma extract, isodose gastrodin in Tiangou Jiangya capsule showed a significant decrease for Cmax, Ke and increase for t1/2Ke, V/Fc, this indicated that compound compatibility can delay the absorbtion of gastrodin, prolong the resident time and promote the distribution in vivo, but its bioavailability is not significantly effected.

Chinese Journal of Rehabilitation Theory and Practice 2002;8(3):166-166
ObjectiveTo observe the effect of comprehensive rehabilitation treatment on clinical nerve function deficiency (CNFD) and activities of daily living (ADL) of the patients with stroke. Methods45 stroke sufferers from different period were divided into three groups (1st group: in one month; 2nd group: one to six months; 3rd group: over six months). Before and after the comprehensive rehabilitation treatment was given, the CNFD, ADL and clinical effect were assessed.ResultsAfter comprehensive rehabilitation treatment, the CNFD of 1st group, and the ADL score of 1st group and 2nd group were improved significantly, and the 1st group's was better than the others. The total effective rate also increased in 1st and 2nd group. Conclusions Early rehabilitation treatment can improve the patient's neural motion function and the activities of daily living.

ObjectiveTo observe the protective effect of tetrahydroxystilbene glucoside (TSG) on rats' hippocampal neuronal damage induced by glutamate (Glu) in the culture.MethodsHippocampus was isolated from newborn SD rats and dispersedly cultured in the medium for 9 days. Neurons were incubated with TSG (5—100μmol/L) for 24h, the cells were washed twice with Lock's solution without Mg2+,then Glu 500 μmol/L was added. Thirty min later, the reaction was terminated by washing the monolayer cells twice with the Lock's solution and then cultures were kept at 37℃ for 24h. Cell viability was measured by MTT method and cell membrane damage was determined by LDH leakage; with Fluo-3/AM as an intracellular calcium indicator and added into the bathing medium, fluorescent intensity of intracellular free calcium were observed through laser scanning confocal microscopy (LSCM).ResultsAfter the treatment with 5—100μmol/L TSG for 24h, the decrease of cell viability and the increase of LDH leakage caused by Glu was obviously resisted dose dependently. TSG inhibited increase of Ca2+ in cytoplasm, compared with model group.ConclusionTSG can significantly promote the cell viability and reduce the cell membrane damage in Glu treating hippocampal neurons. The neuroprotective activities of TGS is mediated by inhibiting Ca2+ overload in cytoplasm.

Objective To evaluate osteoporosis and the bone turnover markers in patients with Graves′ disease(GD) and the association of bone turnover markers including serum osteocalcin ( OCN ),I procollagen Nterminal propeptide( PINP),serum alkaline phosphatase ( ALP),and β- I collagen carboxyl-terminal peptide ( β-CTX)with thyroid hormone levels.Methods A total of 163 patients with Graves′ disease were enrolled.Serum thyroid hormone,OCN,PINP,and β-CTX levels were measured by the method of ethchemiluminescence.Serum ALP,calcium,phosphorus,and urinary calcium/creatinine ratio were measured by automatic biochemical system.Bone mineral density ( BMD ) of lumbar spines 1-4 ( L 1-4 ) and the proximal left femur was detected by dual energy xray absorptiometry.Results GD cases enrolled were composed of 43 men (26.4% )and 120 women ( 73.6% ),with an average age of ( 47 ± 1 ) years.There were 126 cases ( 77.3% ) with normal BMD,and 37 cases ( 22.7% ) with osteoporosis.OCN,ALP,PINP,β-CTX,and free T3 levels were significantly higher in the group of osteoporosis than those in the group with normal BMD( P<0.05 or P<0.01 ) after adjusting for sex,age,and BMI.The levels of OCN,P1NP,and β-CTX were positively correlated with serum FT3 level ( all P<0.01 ) and were also progressively increased according to the quartile groups of FT3 levels ( P<0.01 ) after sex,age,and BMI were adjusted.Conclusion Patients with Graves′ disease had a high incidence of osteoporosis with characristic high rate of bone turnover,which is related to the raised thyroid hormone levels.

Objective To examine the impact of oncology nurses' compassion satisfaction and compassion fatigue on doctor-patient relationship satisfaction.Methods Questionnaire survey was conducted by 388 oncology nurses,the questionnaires include Professional Quality of Life Scale and DoctorPatient Relationship Satisfaction Scale.Results The total scores of compassion satisfaction was 34.22±7.19,the total scores of secondary traumatic was 26.32±6.12,the total scores of job burnout was 25.13±6.08,the total scores of doctor-patient relationship satisfaction was 4.24±0.75.Pearson correlation analysis showed that doctor-patient relationship satisfaction score was positively correlated with oncology nurses' compassion satisfaction (r=0.468,P < 0.05),negatioely correlated with nurses' compassion fatigue factor scores (r=-0.182,-0.531).Regression analysis showed that compassion satisfaction,secondary traumatic,job burnout and night shift frequency were influencing factors of doctor-patient relationship satisfaction,which could explain29.2% of the variance.Conclusions Improvement of the oncology nurses' compassion satisfaction and compassion fatigue can improve the doctor-patient relationship satisfaction and the quality of nursing service,and create a harmonious medical environment.
10.Clinical observation on acupuncture at points of Shaoyang meridians plus moving cupping on the neck and shoulder for migraine
Journal of Acupuncture and Tuina Science 2017;15(5):377-381
Objective:To observe the efficacy of acupuncture at points of Shaoyang meridians plus moving cupping on neck and shoulder for migraine. Methods:A total of 64 migraine cases were randomly allocated into an observation group and a control group, 32 cases in each group. Random number table method was used in allocation. Acupuncture at points of Shaoyang meridians and cupping on neck and shoulder were used for cases in the observation group, which contain acupuncture 5 times a week and cupping once a week. Oral flunarizine hydrochloride capsules were used for cases in the control group, 10 mg for each dose, 1 dose a day. 2 weeks constitutes a course of treatment. The patients were treated for two courses of treatment in both groups. After that, the changes of visual analogue scale (VAS) and the migraine disability assessment questionnaire (MIDAS) were observed, as well as the clinical efficacy. Results:The total effective rate and recovery and marked effective rate in the observation group were 93.8% and 71.0% respectively, versus 78.1% and 43.8% in the control group, showing statistical significant differences (both P<0.05). There were significant decreases in VAS and MIDAS scores after treatments in both groups (both P<0.05). VAS and MIDAS scores in the observation group were significantly different from those in the control group (both P<0.05). Conclusion: Combining acupuncture at points of Shaoyang meridians and cupping on neck and shoulder can relieve headache and reduce influence of migraine on life. It can produce a better efficacy than oral flunarizine hydrochloride capsules in treating migraine patients.
