ABSTRACT
OBJECTIVE:To explore the effect of subarachnoid block anesthesia in endoulogy minimally invasive surgery of el-derly patients. METHODS:198 elderly patients underwent endoulogy minimally invasive surgery were randomly divided into obser-vation group (100 cases) and control group (98 cases). Observation group received subarachnoid block anesthesia,and control group received epidural anesthesia. The anesthesia onset time,anesthesia dose,surgery time,complete block time,satisfaction de-gree of anesthesia effect,the occurrence of ADR were compared between 2 groups. RESULTS:Anesthesia onset time and complete block time of observation group were (1.5 ± 0.6) min and (7.9 ± 3.9)min,which were significantly shorter than those of control group (4.5 ± 1.2) and (17.5 ± 4.3) min,with statistical significance (P0.05). CONCLUSIONS:Subarachnoid block anesthesia consumes small dose,acts rapidly and shows significant anesthesia effect,it is used for endoulogy minimally invasive surgery of elderly patients.
ABSTRACT
Objective To explore the relationship between the levels of Cu, Fe, Mn, Zn in serum and Parkinson disease (PD). Methods A total of 40 patients with PD (PD group) and 40 control subjects (control group)were enrolled in this study. Serum levels of Mn were measured by graphite atomic absorption, and Cu ,Fe, Zn were measured by inductively coupled plasma(ICP)mass spectrometry. Resudts There were significantly increase in the levels of Mn and Fe in PD group than those in control group [(0.269±0.326) μ mol/L vs (0.125±0.054) μmol/L, P< 0.05, (1.512±0.949) μmol/L vs (0.676±0.111) μmol/L, P< 0.01)]. There were no significant difference in the levels of Cu and Zn between two groups (P> 0.05). Condusion Micreelements may play important roles in pathogenesis and development of PD, especially Fe and Mn.
ABSTRACT
Objective: In order to solve the problem of moisture absorption for Biantong Capsule, the extract granule of Chinese medicine is covered with HPMC for Biantong Capsule. Methods: Taking moisture absorption rate as measure index, various facters effected the moisture absorption rate, and the optimal coating process can be selected with well disturbed uniform design and computer analog test. Results: Under the condition of 25℃, relative moisture 75% and 100% respectively, the moisture absorption rate is lower than uncovered granules, the critic relative moisture of covered granules is greater than that of uncovered granules. Conclusion: Chinese medicine of Biantong Capsule covered with HPCM can be served as a good anti moisture method.
ABSTRACT
AIM: To investigate the preparation and parameter of pellets of traditional Chinese medicine in order to solve the problem of preparation of pellets of traditional Chinese medicine. METHODS: We took centrifugal spray method to prepare the pellets, and compared effect of spray coating and fluidzed bed coating on the quality of pellets. RESULTS: The best preparation of pellets was determined as followed. The frequency of turntable was 45 HZ, the flow rate of liquid was 1.2 g/min. the relative density of liquid was 1.20 g/cm 3; when coating weigh reached 14%, the better pellets could be obtained. CONCLUSION: The need of the assistant matter of taking spray pellets and film coating was less and roboticized. It accorded with the answer of GMP and the regular production of the preparation of pellets of traditional Chinese medicine.
ABSTRACT
AIM: To establish the quality standard of Puqinxiaoyan Tablets (Radix Scutellariae, Herba Taraxaci, Herba Corydalis Bungeanae, etc.). METHODS: TLC was used for identification of Herba Taraxaci, Herba Corydalis Bungeanae; HPLC was used for the determination of baicalin. RESULTS: The TLC identification was highly specific and the spots clear and concentrated. The linear range of baicalin was from 0.060～ 0.660?g, r = 0.99991, The recovery of the loading was 97.29%, RSD was 2.13%, respectively. The content of baicalin wasn't less than than 9.0mg per tablet. This method was easy to operate with accurate result, high sensitivity and good reproducibility. CONCLUSION: These methods are able to effectively control the quality of Puqinxiaoyan Tablets.
