Objective To investigate the effects of docosahexaenoic acid (DHA) on the growth of human pancreatic cancer cell lines. Methods Human pancreatic cancer cell lines Patu8988 and SW1990 were treated with DHA. The cell proliferation was evaluated by MTT assay. Cell cycle, apoptosis, and cyclooxygenase-2 ex-pression were evaluated by flow cytometry. Results After incubation of pancreatic cancer cell with DHA for 24 to 72 hours, cell proliferation significantly decreased (P<0. 01) and apoptosis increased, both of which were time- dependent and dose-dependent After incubation with 50μg/ml DHA for 24 hours, cyclooxygenase-2 expression of pancreatic cancer cell lines significantly decreased (P < 0. 05). Conclusions DHA can inhibit the growth of hu- man pancreatic cancer cells via decreasing cell proliferation and inducing apoptosis. These effects may be associat- ed with the decrease of cyclooxygenase-2 expression.

The relationship between acupuncture and stress is discussed from three aspects, including is it possible for acupuncture stimulation to be a stressor, whether acupuncture will start stress reaction, and whether acupuncture effects contain some stress factors. It is believed that correct acupuncture manipulation will not cause stress response, however, under some circumstances, such as inaccurate manipulation, improper treatment or patients who are very nervous but do not receive effective intervention, acupuncture is likely to cause stress response. Acupuncture-induced stress response is totally different from acupuncture anti-stress. The possible stress factors in acupuncture effect are explored, which can provide a new angle for the research on action mechanism of acupuncture. From the view of stress to review acupuncture treatment, there are three enlightenments: emphasizing on communication between doctors and patients, avoiding over-pursuit of deqi and focusing on analysis of the body constitution.

Objective To investigate the diagnosis,preoperative examination and surgical treatment of carotid body tumor(CBT).Methods From December 2008 to December 2012 80 patients of carotid body tumor were treated in our center.The average age was(43:±:12)years,33 cases were male,47 cases were female.The lesions were unilateral in 68 cases and bilateral in 12.All tumors were surgically resected.In 26 of Shamblin Ⅰ,32 of Shamblin Ⅱ and 19 of Shamblin Ⅲ tumors were simply resected.One Shamblin Ⅱ and 2 Shamblin Ⅲ cases underwent tumor resection combined with external carotid embolization.3 Shamblin Ⅱ and 8 Shamblin Ⅲ cases were treated by tumor resection combined with internal carotid reconstruction,1 Shamblin Ⅲ was done with tumor resection combined internal carotid repair.Results All of 80 patients with 92 tumors were successfully resected.There was no death case during peroperative period,while one case developed hemiplegia and 14 cases suffered cranial nerve injuries.68 cases (85％) were followed-up from 1 year to 6 years.Thera were 14 patients with cranial nerve injuries,2 of them were lost to follow-up,11 with complete or partial recovery and 1 was still doing poorly.Conclusions Tumor size and its relation to the carotid artery form the basis upon which appropriate operation is adopted.

Objective To analyze the bibliometry of the literature of acupoint thread-embedding in treating simple obesity, and to provide references for clinic.Method By both computer and manual retrieval, the relevant literatures over the past 30 years were collected from the Chinese Journal Full-text Database (CJFD), Vip database, WanFang database. By using the SPSS 17.0 software for statistical analysis, the distribution (province or city), publication year, and journal of the literatures, supporting fund, sample size, research method, material of the thread, use frequency of the involved acupoints, and the meridians of the selected acupoints were summarized.Result The included eligible 175 articles were distributed over many provinces and cities; the publication amount had been increasing year by year; there was a variety of thread materials; the literature with supporting funds only occupied a small percentage, while the research with a small sample size occupied a comparatively large percentage, and the randomized controlled trials (RCTs) also had a small percentage.Conclusion As a common Chinese external therapy in treating simple obesity, acupoint thread-embedding has been paid more and more attention for its practical value and bright future. However, the relevant governmental department hasn’t paid enough attention to this therapy, and the low clinical research quality also makes it difficult to scientifically evaluate its clinical efficacy and safety. Therefore, more attention is required, RCTs of multicenter and large sample size are expected, and clinical research quality also needs improvement, to provide references for clinic.

Objective To optimize the sulfated modification conditions for Rhizoma Smilacis Glabrae polysaccharides (RSGP),and to investigate the possibility of enhancing the activity of RSGP after sulfating modification.Methods RSGP was modified by cholorosulfonic acid-pyridine.With the yield,carbohydrate content and sulphate substitution degree as the observation indexes,L9 (34)orthogonal design was used to optimize reaction time,reaction temperature and reagent ratio.The degree of sulphate substitution was determined by barium chloride turbitimetry,and the carbohydrate content was detected by sulfuric acid-phenol method.Then the structures of the sulfated modified products were analyzed by infrared radiation (IR) spectrum.Methyl thiazolyl tetrazolim(MTT)assay was used to determine the anti-tumor activity of sulfated RSGP on HepG2 and MCF-7 cell lines.Results The optimized modification conditions of RSGP were sulfating RSGP with cholorosulfonic acid-pyridine in the ratio of 1:6 for 4.5 hours at 60 ℃.The MTT assay results showed that the sulfated RSGP could inhibit the growth and proliferation of human liver cancer HepG2 cell line and human mammary cancer MCF-7 cell line in concentrationdepending manner.Conclusion It is feasible for sulfating modification of RSGP with cholorosulfonic acid-pyridine,and sulfating modification can enhance the anti-tumor activitv of RSGP.

Eight 1,6-O,O-diacetylbritannilactone (OABL) derivatives (compounds 1-8) were synthesized by esterification or reduction of 1-O-diacetylbritannilactone (ABL) isolated from Inula japonica.All derivatives were evaluated for their anti-inflammation activities through the determination of inhibition of nitric oxide (NO) production in lipopolysaccharide (LPS)-induced macrophages.As results,compounds 5-8 (IC50 ＜ 2 μmol/L) exhibited more potent inhibition of NO production activities than the lead compound OABL.

BACKGROUND:Tai Chi exercise can relax the affected muscle of patients, increase muscle flexibility and strength, promote normal movement patterns of stroke patients, inhibit abnormal posture and spasm patterns, improve patient motion control and balance function. OBJECTIVE:To systematicaly assess the effectiveness of Tai Chi on the movement, emotional disorder and quality of life in patients with stroke. METHODS: Al extracted data from databases of PubMed, EMbase, Web of Science, EBSCO, Google Scholar, CNKI, VIP and Wangfang were obtained, which were the randomized controled trials addressing the effects of Tai Chi on the movement, emotional disorder and quality of life in patients with stroke. The retrieval time was from database establishment to July 1st, 2015. According to the inclusion and exclusion criteria, two reviewers independently screened, extracted data and assessed the methodological quality of the included literatures. Then the meta-analysis was conducted using RevMan 5.3 software. RESULTS AND CONCLUSION:A total of 15 randomized controled trials involving 1016 patients were included. The results of Meta-analysis suggested that: Tai Chi was superior to the conventional rehabilitation in improvement of balance function [mean difference (MD)=7.87, 95% confidence interval (CI) (4.56, 11.18),P < 0.000 01], gait speed [MD=0.27, 95%CI (0.04, 3.94),P=0.02], anxiety [standardized mean difference (SMD)=-0.47, 95%CI(-0.89,-0.04),P=0.03] and quality of life [SMD=0.65, 95%CI(0.10, 1.19),P=0.02], and there were statistical differences. But there was no statisticaly significant difference in the improvement of depression and functional walking ability. These findings indicate that Tai Chi is superior to the conventional rehabilitation in the improvement of balance function, gait speed, anxiety and quality of life. However, large-sample, high-quality randomized controled trials are needed to provide more reliable evidence for the effect of Tai Chi in depression and functional walking ability.
