ABSTRACT
Objective:To investigate the construction and application of telemedicine system in Tibet Autonomous Region.Methods:From June to July 2020, medical institutions at all levels in Tibet Autonomous Region were visited. Relevant information was collected through discussion, questionnaires and field visits, and the data of effective questionnaires were statistically analyzed.Results:A total of 125 medical institutions were visited, covering 7 regions of Tibet Autonomous Region, of which 74 medical institutions were able to realize audio-video two-way communication with the telemedicine platform of the PLA General Hospital. Seventy-three valid questionnaires were collected, and 64(88%)hospitals had software or hardware audio and video terminals. Twenty-five hospitals had never carried out remote consultation, accounting for 34%. The annual remote consultation amount of 35 hospitals was less than 10 cases, and that of 11 hospitals was 11-100 cases. Only 2 hospitals had carried out remote ECG and remote ultrasound diagnosis, with an annual consultation volume of more than 100 cases.Conclusions:The hospitals at or above the county level in Tibet Autonomous Region have established telemedicine system, but there are few remote services, the system idle rate is high, and the distance education resources are not matched.
ABSTRACT
Objective:To improve the quality standard for compound Huanghuai tablets. Methods: The main components of the preparation including Flos Sophorae Immaturus, Radix Scutellariae Baicalensis, Radix Paeoniae Rubra, Radix et Rhizoma Rhei Palma-ti, Rhizoma Imperatae, Caulis Spatholobi, Semen Coicis and Spica Prunellae Vulgaris were identified by TLC qualitatively. The content of rutin in Flos Sophorae Immaturus was determined by HPLC. A DIKMA? Spursil C18 (250 mm × 4. 6 mm, 5 μm) column was used with methanol-0. 2% phosphoric acid solution (45:55) as the mobile phase. The flow rate was 1. 0 ml·min-1 , the detection wave-length was set at 350 nm, the column temperature was maintained at 25℃, and the injection volume was 20μl. Results:The spots in TLC were clear without any interference. The calibration curve was linear within the range of 0. 0116-0. 1859 mg · ml-1 ( r =0. 9999) for rutin. The average recovery was 98. 93% (RSD=1. 14%,n=6). Conclusion: The improved quality standard is sim-ple, specific and reproducible, which can be used for the quality control of compound Huanghuai tablets.
ABSTRACT
Objective To investigate the effect of minocycline on isoflurane-induced hippocampal neuroapoptosis and cognitive dysfunction in aged rats. Methods Forty-five male SD rats were randomly assigned into 3 groups ( n=15): blank control group ( group C) , 1.5% isoflurane group ( group I) and 50 mg??kg-1 minocycline+1.5% isoflurane group ( group M+I) . Minocycline was injected intraperitoneally 12 h before the start of anesthesia for group M+I.Group I and group M+I were exposed to 1.5% isoflurane for 4 h, while group C were exposed to 30% O2-70% N2.At the end of anesthesia, five rats in each group were randomized to analyse arterial blood gas. The other rats in each group were sent back to their home cage until they were fully awake.Fourteen days after anesthesia, Morris water maze was used to assess the cognitive function, and then hippocampi of rats were dissected for detection of the expression of cleaved caspase3, Bax and Bcl-2. Results No difference was found in arterial gas analysis among the 3 groups (P>0.05).Compared with group C, the rats in the group I spent more time locating the platform on the third and fourth training days and the time percentage that the rats in group I spent in the target quadrant was much less (P<0.05).However, these changes were reversed in group M+I (P<0.05).The isoflurane-induced increased level of Bax and cleaved caspase3 and decline of anti-apoptotic factor Bcl-2 were restored by minocycline pretreatment ( P<0.05) . Conclusion Minocycline could attenuate cognitive dysfunction induced by isofluranein aged rats.The mechanism is associated with inhibition of hippocampal neuroapoptosis which is increased by isoflurane.
ABSTRACT
Aiming at the characteristics of telemedicine service,we summarized our telemedical consultation work during 2006-2008.We believed that telemedical consultation from big hospitals are very important in maintaining physical and moral health conditions and treating severe sickness of grassroots officers and soldiers,it can also play active roles in the construction of basic army unit hospitals.
