[Rules of acupoint selection and drug use in clinical treatment of hypertension with acupoint application therapy].

OBJECTIVE: To explore the rules of acupoint selection and drug use in treatment of hypertension with acupoint application therapy. METHODS: The articles of the clinical research of hypertension treated with acupoint application therapy were retrieved from Chinese journal full-text database (CNKI), VIP database (VIP) and Wanfang databases from the time of establishment to January 20, 2019. The database was set up with Microsoft Excel 2010. Using the cloud platform of the ancient and modern medicine record, the frequency statistical and clustering analyses were conducted. RESULTS: A total of 117 articles were collected, including 191 prescriptions, 60 aucpoints and 236 kinds of herbal drugs. It was found in the frequency statistical analysis that the top 6 acupoints in use frequency were Yongquan (KI 1), Quchi (LI 11), Taichong (LR 3), Shenque (CV 8), Sanyinjiao (SP 6) and Neiguan (PC 6). According to the correlation analysis, corresponding to these top 6 acupoints, the pairs of acupoints were Sanyinjiao (SP 6) and Yongquan (KI 1), Shenque (CV 8) and Yongquan (KI 1), Neiguan (PC 6) and Yongquan (KI 1), Zusanli (ST 36) and Sanyinjiao (SP 6), Sanyinjiao (SP 6) and Neiguan (PC 6) with Yongquan (KI 1), as well as Yongquan (KI 1) and Neiguan (PC 6) with Sanyinjiao (SP 6). The dominant meridians were the kidney meridian, the conception vessel and the bladder meridian. The special acupoints referred to yuan-source point, luo-connecting point, back-shu point and front-mu point. The top 3 herbal drugs in use frequency included fructus evodiae, semen sinapis and rhizoma chuanxiong. The herbs used were mainly warm and slight cold in nature and neutral in property. The frequencies of the drug use were similar in the application for cold and heat purposes. The common flavors of the herbal medicines were pungent, sweat and bitter and the liver, kidney and spleen meridians were generally involved in meridian tropism. CONCLUSION: In treatment of hypertension with acupoint application therapy, the commonly used single acupoint is Yongquan (KI 1), which is generally combined with Sanyinjiao (SP 6), Shenque (CV 8), Neiguan (PC 6) and Zusanli (ST 36). The correlation is emphasized on the application of special acupoints, meridian points and zangfu organs. The vesicatory herbal drugs are predominant in the drug use. In generally, this therapy embodies the treatment principles as tonifying for the deficiency and reducing for the excess, as well as balancing of cold and heat.

Efficacy of autologous peripheral blood mononuclear cells in treatment of high radial nerve injury / 中国组织工程研究

OBJECTIVE: To investigate the efficacy of autologous peripheral blood mononuclear cells in the treatment of high radial nerve injury. METHODS: From April 2011 to September 2015, 12 cases of radial nerve injury in the middle arm were treated. Preoperatively peripheral blood mononuclear cells were mobilized, and then 15 mL of mononuclear cell suspension was prepared on the operation day. Radial nerves scheduled for anastomosis were surgically explored and subjected to end-end anastomosis using outer membrane suturing under microscope. The anastomotic site of the nerve was enveloped with gelatin sponge soaked with 5 mL of autologous peripheral blood mononuclear cell suspension. The remaining 10mL of cell suspension was used for a multi-point injection into the local muscles, 0.5 mL at each point. Thereafter, the deep fascia and the incision were sutured in sequence. Postoperative antibiotic treatment was used to prevent infection for 48 hours, and upper limb immobilization lasted for 4 weeks. Performance of rehabilitation exercise was guided. During the follow-up, wrist dorsal extension and muscle strength of extensor carpi ulnaris and extensor digitorum communis were detected to evaluate the therapeutic efficacy. RESULTS AND CONCLUSION: All the patients were followed up for 15 to 36 months, with an average of 17 months. Efficacy was excellent in 9 cases, good in 2 cases, fair in 1 case and poor in 0 case. The excellent and good rate was 92%. The wrist dorsal extension could achieve the functional needs, and the thumb dorsal extension and finger extension basically met the functional requirements. It is suggested that autologous peripheral blood mononuclear cell transplantation can achieve good outcomes in the treatment of high radial nerve injury.

[Evaluation of a pilot study on needle and syringe exchange program among injecting drug users in a community in Guangdong, China].

OBJECTIVE: To evaluate the feasibility and effectiveness of needle and syringe exchange program among a community of injecting drug users (IDUs) on AIDS prevention. METHODS: A quasi-experiment design was used in a controlled community intervention study. Needle and syringe exchange program was implemented for 10 months in IDUs of an intervention community, including peer education and health education, provision of free needles and syringes, and collecting back of used needles and syringes by trained peer educators and local health workers, whereas no intervention measure in a control community was instituted. Interviews with IDUs were conducted before and after intervention with a snowballing strategy to evaluate its effectiveness. RESULTS: A total of 428 and 429 IDUs were interviewed with structured questionnaire before and after intervention in intervention and control communities, respectively. Results revealed that awareness of HIV-related knowledge increased from 29.4% to 58.7% in the intervention community. Multivariate logistic regression analysis showed that awareness of HIV-related knowledge was higher in those who had read health education materials (OR = 2.93, 95% CI 2.12 - 4.04). As compared with the baseline data, frequency of sharing needles and syringes in past 30 days in the intervention community decreased from 48.9% to 20.4% in before intervention community (chi(2) = 41.02, P = 0.001), whereas there was no significant change in the control community. The causes of sharing needles and syringes in the intervention community included 'disable to get needle and syringe during the night', 'lack of needle and syringe when injecting at friend's home', 'not daring to buy needle and syringe for fear of being arrested' and 'no money to buy needle and syringe', declined markedly. CONCLUSIONS: Needle and syringe exchange program was feasible and effective in reducing their risky drug injecting behavior among IDUs in communities. Such strategy should be adopted in the country to reduce rapid spread of HIV.
