Objective To develop a method for determination of catechins and alkaloids in brick-tea by high performance liquid chromatography(HPLC) with diode array detection(DAD),and to explore optimum extraction conditions for catechins and alkaloids components in brick-tea.Methods Catechins and alkaloids were separated and detected by HPLC.Orthogonal experiment and paired t test was carried out to compare the effect of water and alcohol as extraction solvents and to obtain optimum extraction conditions for extracting catechins and alkaloids components in brick-tea.Results Six kinds of catechins of catechin,epicatechin,gallocatechin,epigallocatechin,epicatechin gallate,epigallocatechin gallate and two kinds of alkaloids of caffeine and theobromine were separated and detected simultaneously.Calibration curves between peak areas and concentration of each component in bricktea were linear within a suitable concentration range,and coefficients of determination (R2) were between 0.9990-0.9999; spiked recoveries were from 83.78% to 106.35%,and relative standard deviations(RSD) were between 0.50%-1.51%.The optimum extraction condition for catechins and alkaloids was 80% ethanol,solid-liquid ratio of 1:10,temperature 80 ℃ and extraction time 30 min.Conclusion Alcohol as extraction solvents with optimal combination on HPLC,six kinds of catechins and two kinds of alkaloids are separated accurately,qualitatively,rapidly and sensitively.

OBJECTIVETo explore an optimal anesthesia method with less impact on hemodynamics and electrocardiogram (ECG) of old patients with coronary artery disease (CHD) during abdominal operation.
METHODSThe 133 CHD patients waiting for abdominal operation were randomly divided into continuous epidural anesthesia (EA) group, general anesthesia group (GA) and combined spinal-epidural anesthesia (CSEA) group. Continuous monitoring was carried out during operation and mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SaO2), abnormal ECG were measured respectively at different time for comparison and the differences of the above hemodynamic parameters and abnormal ECG features were compared among the 3 groups.
RESULTSAt the 15 min and 30 min point after anesthesia, SaO2 in GA group was significantly increased compared to that in the EA group (P < 0.05). At 15 min, 30 min and 60 min point after anesthesia, MAP in CSEA group was significantly increased compared to that in the EA group (P < 0.05). At 30 min point after anesthesia, HR in CSEA group was increased significantly compared to the EA group (P < 0.05). At 15 min and 30 min point after anesthesia, SaO2 in the CSEA group was increased significantly compare to the EA group (P < 0.05). Compared with preanesthesia (T0) in EA group, MAP, HR and SaO2 decreased significantly at 15, 30 and 60 min after anesthesia (P < 0.05). The fluctuation of the three parameters in GA and CSEA groups were relatively small (P > 0.05). As well as the comparison of abnormal ECG among the 3 groups was concerned, the incidence of ST-T changes in GA and CSEA groups were significantly lower than that in EA group at the time of 15 min, 30 min and 60 min after anesthesia and at the time of surgery termination (P < 0.05, P < 0.01). The incidence of arrhythmia in GA and CSEA groups were significantly lower than that in EA group at the time of 15 min, 30 min and 60 min after anesthesia (P < 0.05, P < 0.01). Compared with T0 in the same group, the incidences of ST-T changes and arrhythmia in GA or CSEA group at the time of 15, 30 and 60 min after anesthesia and at the time of surgery termination were significantly lower than that before anesthesia (P < 0.05, P < 0.01).
CONCLUSIONGA and CSEA have less impact on hemodynamics and have smaller incidence of abnormal ECG of old CHD patients with abdominal operation.

OBJECTIVETo explore effective therapeutic methods for sensorineural hearing loss (SNHL).
METHODSThirty-four cases of mild and moderate SNHL who were definitely diagnosed with pure tone test and by otologists, including 24 cases of insufficiency of the liver and kidney, 10 cases of excess of liver-fire. They were treated with acupuncture at main points, Ermen (TE 21) or Tinggong (SI 19) or Tinghui (GB 2), and Yifeng (TE 17), Shenting (GV 24), Baihui (GB 20), Houding (GV19), Touwei (ST 9), Conger 1-3, Congnao 1-2; and adjuvant acupoints: Huangshu (KI 16), Qihai (CV 6), Guanyuan (CV 4), Taixi (KI 3) were added for insufficiency of the liver and kidney; Zhongwan (CV 12), Tianshu (ST 25), Yanglingquan (GB 34) and Taichong (LR 3) were added for excess of liver-fire. Sequential multipoint pulse stimulation was adopted, twice each week, for 20 consecutive weeks (40 sessions) and then pure tone test was carried out repeatedly.
RESULTSOf 34 cases (58 affected ears), 13 cases were cured and 21 improved, and the various linguistic frequency hearing threshold pure hearing values before and after treatment increased significantly (P < 0.05).
CONCLUSIONAcupuncture and continuous multipoint pulse stimulation has definite therapeutic effect on linguistic frequency hearing loss in the patient of SNHL.

Objective To evaluate the efficacy and safety of diacerhein in the treatment of patients with knee osteoarthritis.Methods The efficacy and safety of diacerhein was randomly investigated in 42 pa- tients with knee osteoarthritis using parallel group methodology and a double-dummy technique to ensure dou- ble blind status with respect to diacerhein and control drugs diclofenac.Results Significant changes were ob- served in 20 meters walk pain,knee joint tenderness scale,WOMAC index scale,5F-36 health survey,knee joint swelling scale,compared with baseline(P>0.05)in both diacerhein and diclofenac group respectively.No difference was found between diacerhein group and diclofenae group.The patient global assessment and physi- cian's global assessment were similar in diacerhein group and diclofenac group(P>0.05).The side effect was similar in two groups.All of these side effects in gastrointestinal tract appeared to be transient.Conclusion Diacerhein can effectively relieve pain and swelling of knee osteoarthritis,and provides us a new effective and safe approach for treating knee osteoarthritis.

ObjectiveTo observe the effect of progesterone on progesterone receptor in brain tissue with hypoxia-ischemia brain da-mage(HIBD) in neonatal rats,and discuss the protective mechanism of progesterone on HIBD of neonatal rats.MethodsTwenty-four 7-day-old neonatal rats were randomly divided into 3 groups:sham-operated group,hypoxia-ischemia group and pretreatment group.Rats in hypoxia-ischemia group and pretreatment group were subjected to left common carotid artery ligation,then were exposed to 80 mL/L oxygen and 920 mL/L nitrogen gas in 37 ℃ closed container for up to 2.5 h to establish hypoxia-ischemia encephalopathy(HIE) model.Progestero-ne was injected intraperitoneally into pretreatment group rats respectively at 30 minutes before hypoxia,solution was injected into the first 2 groups.All rats were killed at the 24 hour after operation,immunohistochemistry staining was used to examine the expression of progesterone receptor in brain.ResultsTotally 24 neonatal rats entered the result analysis without loss.Progesterone receptor was expressed in both endochylema and nucleus in every group rat.The amount of the positive cell of progesterone receptor in hypoxia-ischemia group significantly decreased compared with that in sham-operated group(P
