[Effect of auricular point sticking therapy on perioperative pain in patients with partial lung resection].

OBJECTIVE: To observe the analgesic effect of auricular point sticking therapy during the perioperative stage in the patients with partial lung resection. METHODS: A total of 92 patients with partial lung resection were randomized into an auricular point group (31 cases, 1 case dropped off), the sham-auricular point group (30 cases) and a medication group (31 cases, 1 case dropped off). The routine medication for analgesia was provided in all of the three groups. In the auricular point group, 1 day before operation, the auricular point sticking therapy was applied at shenmen (TF4), sympathetic (AH6a), subcortex (AT4), brain stem (AT3,4i), anterior ear lobe (LO4), chest (AH10) and lung (CO14), retained till the third day after operation. In the sham-auricular point group, the auricular adhesive tape without semen vaccariae was used at the same points as the auricular point group. Separately, the scores of visual analogue scale (VAS) in 8, 16, 24, 48 h and 72 h after operation, the time for obtaining the mean of the postoperative VAS score<3 points, the scores of hospital anxiety and depression scale (HAD) in 8, 72 h after operation and the plasma concentration of ß-endorphin in 24, 48 h after operation, as well as the adverse reactions after operation were recorded in the patients of each group. RESULTS: In 8, 16, 24, 48 h and 72 h after operation, VAS scores in the auricular point group were lower than those in the sham-auricular point group and the medication group separately (P<0.05). In the auricular point group, 16 h after operation the mean of VAS score was less than 3 points, but in the sham-auricular point group and the medication group, 48 h after operation, such a mean score of VAS was obtained. In 8, 72 h after operation, HAD score in the auricular point group was lower than that in the sham-auricular point group and the medication group respectively. In 24, 48 h after operation, the concentration of plasmaß-endorphin was all higher than that in the sham-auricular point group and the medication group respectively (P<0.05). In 24 h after operation, the plasma concentration ofß-endorphin in the sham-auricular point group was higher than the medication group (P<0.05). The incidence of adverse reaction in the auricular point group was lower than that in the sham-auricular point group and the medication group respectively (P<0.05). CONCLUSION: Auricular point sticking therapy relieves perioperative pain, shortens analgesic time, releases anxious and depressive emotions and reduces postoperative adverse reaction in the patients with partial lung resection. The analgesic mechanism is probably related to the increase of plasma concentration of ß-endorphin.

Acupuncture and vitamin B12 injection for Bell's palsy: no high-quality evidence exists.

OBJECTIVE: To assess the efficacy of acupuncture combined with vitamin B12 acupoint injection versus acupuncture alone to reduce incomplete recovery in patients with Bell's palsy. DATA RETRIEVAL: A computer-based online retrieval of Medline, Web of Science, CNKI, CBM databases until April 2014 was performed for relevant trials, using the key words "Bell's palsy or idiopathic facial palsy or facial palsy" and "acupuncture or vitamin B12 or methylcobalamin". STUDY SELECTION: All randomized controlled trials that compared acupuncture with acupuncture combined with vitamin B12 in patients with Bell's palsy were included in the meta-analysis. The initial treatment lasted for at least 4 weeks. The outcomes of incomplete facial recovery were monitored. The scoring index varied and the definition of healing was consistent. The combined effect size was calculated by using relative risk (RR) with 95% confidence interval (CI) using the fixed effect model of Review Manager. MAIN OUTCOME MEASURES: Incomplete recovery rates were chosen as the primary outcome. RESULTS: Five studies involving 344 patients were included in the final analysis. Results showed that the incomplete recovery rate of Bell's palsy patients was 44.50% in the acupuncture combined with vitamin B12 group but 62.57% in the acupuncture alone group. The major acupoints were Taiyang (EX-HN5), Jiache (ST6), Dicang (ST4) and Sibai (ST2). The combined effect size showed that acupuncture combined with vitamin B12 was better than acupuncture alone for the treatment of Bell's palsy (RR = 0.71, 95%CI: 0.58-0.87; P = 0.001), this result held true when 8 patients lost to follow up in one study were included into the analyses (RR = 0.70, 95%CI: 0.58-0.86; P = 0.0005). In the subgroup analyses, the therapeutic effect in patients of the electroacupuncture subgroup was better than in the non-electroacupuncture subgroup (P = 0.024). There was no significant difference in the incomplete recovery rate by subgroup analysis on drug types and treatment period. Most of the included studies were moderate or low quality, and bias existed. CONCLUSION: In patients with Bell's palsy, acupuncture combined with vitamin B12 can reduce the risk of incomplete recovery compared with acupuncture alone in our meta-analysis. Because of study bias and methodological limitations, this conclusion is uncertain and the clinical application of acupuncture combined with vitamin B12 requires further exploration.

Aqueous extract of Gleditsia sinensis Lam. fruits improves serum and liver lipid profiles and attenuates atherosclerosis in rabbits fed a high-fat diet.

ETHNOPHARMACOLOGICAL RELEVANCE: Gleditsia sinensis Lam. has been used in the traditional Chinese medicine as a chief ingredient of many polyherbal formulations for the treatment of obesity and thrombosis. AIM OF THE STUDY: To evaluate the effects of Gleditsia sinensis Lam. fruit aqueous extract (GAE) on hyperlipidemia and atherosclerosis in Japanese white rabbits on a high fat diet. MATERIALS AND METHODS: Rabbits were divided into four groups: the normal control with a normal diet, and high-fat diet-fed model group and GAE-treated groups supplemented with GAE (6 or 12 mg/kg/day, p.o.), respectively. The groups fed high-fat diets were given i.v. with bovine serum albumin (BSA) on the 4th week to induce atherosclerosis. The serum lipid profile, including triglycerides (TG), total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C), was determined on the 0th, 4th, 8th and 14th week, respectively. And the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and creatine kinase (CK) were measured simultaneously. At the end of the experiment, the rabbits were sacrificed, and the atherosclerotic plaques as well as the histopathological changes of aorta and liver were assessed by oil-red or HE staining, respectively, and the aorta and liver lipid profiles were also assayed. RESULTS: Results showed that the prophylactic treatment with GAE could significantly decrease the lipid levels of serum, aorta and liver, attenuate aortic atherosclerosis and improve aortic remodeling without the significant liver and muscle toxicity. CONCLUSION: The present findings suggest that GAE can effectively attenuate the atherosclerotic at least through anti-hyperlipidemic activity and thus has the therapeutic potential in treating hyperlipidemia-related cardiovascular diseases.

Saponins isolated from the root of Panax notoginseng showed significant anti-diabetic effects in KK-Ay mice.

Panax notoginseng, a well-known and commonly used traditional Chinese herb, has been used in China for six hundred years. Panax notoginseng saponins (PNS) were extracted from the root of the plant. This is the first study on anti-hyperglycemic and anti-obese effects of PNS in genetic model mice. Additionally, the preventive effect on diabetic nephropathy was investigated. Animals received intraperitoneal injections of PNS 50 or 200 mg/kg daily. On day 12, 22 and 30, PNS-treated groups had significantly lower fasting blood glucose levels and smaller body weight incremental percentage. After a 12-day treatment, glucose tolerance of PNS groups were significantly improved; these indices in PNS-treated mice exhibited a dose-dependent improvement. Furthermore, on day 30, the serum insulin resistance index and triglyceride levels of PNS-treated groups decreased significantly, and the development of the mice glomerular lesions was prevented significantly. The results in this present paper indicate that PNS possesses anti-diabetes and anti-obese activities and may prove to be of clinical importance in improving the management of type 2 diabetes.
