ABSTRACT
Objective To compare the vibrating perception threshold (VPT) between normal subjects and subjects with cervical spondylosis of nerve root type, and to observe the clinical efficacy of acupoint injection at Quyuan (SI13) in releasing pain in cervical spondylosis of nerve root type.Method Sixty-three patients with cervical spondylosis of nerve root type were recruited and randomized into a treatment group of 35 cases and a control group of 28 cases. The treatment group received acupoint injection at Quyuan, and the control group received acupoint injection at Jiaji (EX-B2) points. The short-form McGill Pain Questionnaire (MPQ) was adopted. From the questionnaire, the Pain Rating Index (PRI), sensory (S), affective (A), and total (T) pain rating indexes, Visual Analogue Scale (VAS), and Present Pain Index (PPI) were used to comprehensively evaluate the pain improvement and to quantify the therapeutic efficacy, and the VPT was also considered. The Clinical Assessment Scale for Cervical Spondylosis (CASCS) by West China Rehabilitation Center was also used to analyze the result in the treatment group.Result After the intervention, the MPQ and VAS scores in the treatment group were significantly lower than those in the control group (P<0.05). The total effective rate of the treatment group was significantly higher than that of the control group (P<0.05). Meanwhile, the VPT was improved after the treatment.Conclusion Acupoint injection at Quyuan can produce a more significant efficacy than at Jiaji (EX-B2) in treating cervical spondylosis of nerve root type.
ABSTRACT
OBJECTIVE:To establish a method for the simultaneous determination of curdione,germacrone and furanodiene of zedoray turmeric oil in Ruxiankang injection. METHODS:HPLC was performed on the column of Zorbax SB-C18 with mobile phase of acetonitrile-water (gradient elution) at a flow rate of 1.0 ml/min,detection wavelength was 216 nm,column temperature was 30℃,and the injection volume was 10 μl. RESULTS:The linear range was 60-480 μg/ml for curdione(r=0.999 0),40-320 μg/ml for germacrone(r=0.999 0)and 40-320 μg/ml(r=0.999 0);RSDs of precision,stability and reproducibility tests were lower than 2.0%;recoveries were 95.21%-99.89%(RSD=1.6%,n=6),102.33%-104.89%(RSD=1.0%,n=6)and 97.38%-99.06%(RSD=0.7%,n=6),respectively. CONCLUSIONS:The method is simple and accurate,and can be used for simultaneous contents deter-mination of curdione,germacrone and furanodiene of zedoray turmeric oil in Ruxiankang injection.
ABSTRACT
Objective To study the development of Arbidol hydrochloride(Ahyd) multi-layers controlled-released preparation and evaluate its release rate in order to provide the basis for Ahyd pharmacodynamics reseach.Methods Ahyd multi-layers was used as experiment group and Ahyd single-layer as control,high performance liquid chromatography(HPLC) was used to examine releasing level of two groups for calculating parameters of drug metabolism and bioavailability.Results Compared with Ahyd single-layer,the multi-layers controlled-released preparation had several significant advantages as below:Cmax fell remarkably(P
ABSTRACT
Abdominal breathing is an effective training method for relaxation.It is applicable for resolving sub-health problems in autonomic nervous malfunction and curing some kinds of psychosomatic disorders.In order to improve its training effect,we develop a kind of abdominal breathing training instrument on the basis of the principle of biofeedback.With both features of biofeedback and breathing training apparatus,it may simultaneously feedback the training effect to the trainer during the abdominal breathing training,and the trainer may regulate his breathing mode for desirable effects.In this paper,the instrument is described in such aspects as the circuit design,composition and clinical application.It is an economical,safe and effective instrument,which can be used in Health Promotion Project.
ABSTRACT
Objective To detect EB virus in peripheral blood of patients with non-hodgkin lymphoma (NHL) by ramification amplification method (RAM).To investigate the relativity of NHL with infection of EB virus.Methods RAM was used to detect EB virus with the man-made target gene sequence of promotor of EBER-1. In 120 cases of patients with NHL, EB virus were detected by RAM, and the result of RAM was compared with that of PCR.Raji cells and NB4 cells were used as positive control and negative control respectively.Results RAM could detect 10 molecular target gene of the exponent.76 cases were positive in 120 cases of NHL patients and the positive rate was 63.3%, The result is identical with that of PCR.Conclusion Ramification amplification method is sensitive, convenient and easy to perform.NHL has a high relativity with infection caused by EB virus.
ABSTRACT
Objective Satellite cells(SCs) transplantation was tried to improve cardiac function in this experiment.Methods A myocaridium infarction was created in 23 male Suzhong pigs by ligating the diagonal ramus,and the alive pigs were divided into the experimental group and the control group.SCs were extracted,purified,cultured by modified Dorfman method,and were transplanted into myocardium by intramyocardial injection.By pathomorphological research,we observed the therapeutic outcomes of heart failure.Results ⑴10 pigs were alive(5 in the control group,and the other 5 in the experimental group).The successful rate of making mould was 43 5%.⑵After cultured in vitro for 3 days,SCs were spindle-shaped,and sticked to walls.SCs growth were stasis and each other fusing into form myotube when we delayed to divede Petri dishs or reduced the concentration of Fetus Bovine Serum(FBS) in the culture medium.⑶In the experimental group,neonate skeletal muscle cells were observed in the infarction regions,which were multi-nuclei near edges.These cells aligned in an accordance direction.Intercalated disks were not found between them.The capillary density in experimental group was much higher than the control group.Conclusions Autograft of SCS can be alive in acceptor,and improve the heart function by altering cardiac compliance and configuration,or by stimulating the blood capillary proliferation.SCs don't form intercalated disks with remnant myocardial cells,so synchro-contraction will not occur between them,but malign arrhythmia are not found.
ABSTRACT
Objective To evaluate the possible effect of percutaneous transluminal coronary angioplasty(PTCA) on myocardial injury. Methods Serum cTnI and CK MB levels were measured in 173 patients with coronary artery disease undergone PTCA before and 6, 12, 24, 48 and 72 hours after the procedure. Cardiac events during follow up in these patients were recorded. Results Serum cTnI level was increased after PTCA in 42 patients, remained normal in 84, and was over baseline level before and after the procedure in 47. Serum CK MB level was above baseline before and after the procedure in one patient and increased in 10. Compared with normal cTnI group, elevated cTnI was related to total balloon inflation time, total pressure, number of dilation and stents deployed, contrast medium dose and occurrence of angina during balloon inflation ( P 0.05). Conclusion cTnI was more sensitive and specific than CK MB in identifying minor myocardial injury during PTCA. This injury was related to the intensity of PTCA, but not enough to make worse influence on overall outcome.
