Edema, as one of common clinical diseases, could be treated by taking medicines and adopting external therapies with traditional Chinese medicines (TCM). In recent years, there have been many clinical and basic studies concerning external therapies with TCM on edema Data showed that the external therapies are mostly composed of such purgating drugs as Rhei Radix et Rhizoma, Natrii Sulfas and Pharbitidis Semen, heat-clearing drug such as Phellodendri Chinensis Cortex and resuscitation-inducing drug such as Borneolum Syntheticum. The study showed that ingredients of external therapies did not pass through hilum and hepatic system, and thus avoided the first pass effect of livers. They enabled effective components of drugs to be rapidly absorbed through pores and skins, strengthened the effect against edema, shortened the treatment course, decreased side effects, and were convenient and inexpensive. External therapies with TCM could play unique advantages in inhibiting edema in the future clinical studies.

Objective To investigate the effect of dexmedetomidine on median effective target effect-site concentration ( EC50) of sufentanil inhibiting body movement evoked by skin incision in patients undergoing bilateral subtotal thyroidectomy. Methods Thirty-nine ASA I or II patients of both sexes aged 20-64 yr with a body mass index of 20-25 kg/m2 undergoing bilateral subtotal thyroidectomy were randomly divided into 2 groups: control group (group C) and dexmedetomidine group (group D). The patients were premedicated with intramuscular phenobarbital 0.1 g and scopolamine 0.3 mg. In group D dexmedetomidine 0.6 μg/kg was injected iv over 10 min at S min before induction of anesthesia. Anesthesia was induced with target-controlled infusion (TCI) of propofol and sufentanil. The target plasma concentration of propofol was set at 3.0 μg/ml which was maintained until the end of operation. TCI of sufentanil was started at 10 min after initiation of propofol TCI. The initial target effect-site concentration was set at 0.20 ng/ml and decreased/increased by 20% in the next patient according to whether the patient's body moved or not within 1 min after skin incision. Laryngeal mask airway was inserted at 3 min after initiation of sufentanil TCI. Spontaneous breathing was maintained. Skin incision was made at 10 min after initiation of sufentanil TCI. The EC50 and 95% confidence interval (CI) of sufentanil inhibiting skin incision-evoked body movement were calculated with sequential method. Results EC50, of sufentanil was 0.1148 ng/ml (95% CI 0.1055-0.1249 ng/ml) in group D and 0.1454 ng/ml (95% CI 0.1339-0.1580 ng/ml) in group C, and was significantly lower in group D than in group C. Conclusion Dexmedetomidine 0.6 μg/kg infused iv before operation can reduce the EC50 of sufentanil inhibiting body movement evoked by skin incision in patients undergoing bilateral subtotal thyroidectomy.

Objective To investigate the effect of electro-acupuncture on the spinal nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) signal pathway in a rat model of neuropathic pain (NP). Methods Forty-eight pathogen-free male SD rats weighing 190-210 g were randomly divided into 3 groups (n = 16 each):group Ⅰ sham operation (group S); group Ⅱ group NP and group Ⅲ electro-acupuncture + NP (group E). NP was induced by chronic constrictive injury (CCI). Right sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1 mm intervals with 4-0 chromic catgut. In group E Huantiao and Weizhong points on the operated side were stimulated with electric stimulator (frequency 2 Hz, wave length 0.6 ms, starting at a voltage of 1mA and increasing by 1 mA every 10 min) for 30 min once a day at 11-17 d after CCI. Pain threshold to mechanical and thermal nociceptive stimuli was measured before (T0 , baseline) and at 10 and 16 d after CCI (T1, T2). The animals were sacrificed at 17 d after CCI and the lumbar segment (L4-6) was removed for determination of the activities of total NO synthase (tNOS), induced and neural NOS (iNOS, nNOS) (by spectrophotometry), NO content (by nitrate reductase method) and cGMP content (by immuno-histochemistry) in the spinal cord in 8 animals and the expression of iNOS and nNOS in the dorsal horn of the spinal cord (by immuno-histochemistry) in another 8 animals in each group. Results CCI significantly decreased the mechanical and thermal pain threshold at T1 and T2 as compared with the baseline at T0 in group NP and E. Hyperalgesia induced by CCI was significantly attenuated by electro-acupuncture at T2 in group E as compared with group NP.CCI significantly increased tNOS and nNOS activities, NO and cGMP content in the spinal cord and up-regulated nNOS expression in the spinal dorsal horn. Electro-acupuncture significantly attenuated the CCI-induced increases in tNOS and nNOS activities, NO and cGMP content in the spinal cord and nNOS expression in the spinal dorsal horn. There was no significant difference in the iNOS activity among the 3 groups. Conclusion NO-cGMP signal pathway in the spinal cord is involved in the acupuncture analgesia.

Objective:To explore the mental health status of overseas medical students during the COVID-19 epidemic, so as to provide references for the improvement of their mental health level.Methods:Symptom Checklist 90 (SCL-90) was applied to make a survey online among 118 overseas medical students. SPSS 19.0 was used for statistical analysis, and independent sample ttest and univariate analysis were conducted between the groups. Results:The analysis showed that during the COVID-19 epidemic, the scores of SCL-90 factors of overseas medical students in China were significantly higher than those of Chinese youth norms ( P<0.001). The top four scores were as follows: obsessive-compulsive symptoms > paranoia ideation > interpersonal sensitivity > depression. The positive screening rate for SCL-90 of the overseas students was 40.4%. The scores of male overseas students were significantly higher than those of female students ( P<0.01). The scores of overseas students living outside China at present were significantly higher those of students living in China and on campus ( P<0.001). Conclusion:The mental health status of the overseas medical students needs to be attached great importance during the COVID-19 epidemic. Targeted psychological counseling and intervention should be given to foreign students both staying outside China and those on campus.

To alleviate the shortage of excellent talents of traditional Chinese medicine (TCM), the State Administration of Traditional Chinese Medicine has decided to cultivate a group of talents with strong theoretical foundation, rich practical experience and exquisite skills who would like to devote themselves to TCM technology research. The national talent training program for inheritance of characteristic TCM technology is a major breakthrough in the history of new China in the cultivation of high-level TCM technology talents. A retrospective analysis was performed on the national talent training program for inheritance of characteristic TCM technology hold in training bases from Beijing, Shanghai, Guangdong Province, Jiangsu Province, Anhui Province, Xinjiang Uygur Autonomous Region, Inner Mongolia Autonomous Region, Heilongjiang Province, Yunnan Province, Sichuan Province, Shaanxi Province and Fujian Province. Based on the completion assessment work of 2014 and 2015 national talent training program for inheritance of characteristic TCM technology, and after knowledge exchange and discussion with the training subjects from 30 provinces and some teaching experts in the field of characteristic TCM technology, this paper summarizes the work of the national talent training program for inheritance of characteristic TCM technology. After trained in bases in China, training subjects' theoretical knowledge and practical skills as well as their comprehensive capacity have been greatly promoted. At the same time, there are also some problems and shortages. For example, characteristic TCM technology in some training bases is not prominent enough, some characteristic TCM technologies are not well inherited, and the affiliations of some training subjects do not pay enough attention to it. All of these problems should be solved and improved in future work.
