Acupuncture for the relief of hot flashes in breast cancer patients: A systematic review and meta-analysis of randomized controlled trials and observational studies.

OBJECTIVE: To critically assess the effectiveness and safety of acupuncture for treating hot flashes (HFs) among breast cancer (BC) patients, and to get much more highly compelling evidence then to guide clinical practice. METHODS: Comprehensive systematic literature searches were carried out for identifying randomized controlled trials and observational studies (OSs) published before January 2015. The meta-analysis (MA) was performed by Review Manager 5 software if data could be merged routinely, if not descriptions would be given. RESULTS: A total of 18 studies were eligible ultimately. With respect to HFs frequency, the MA during treatment showed a significant difference (MD = -1.78, 95% confidence intervals [95% CIs]: -3.42--0.14), but no statistical differences were observed when posttreatment or follow-up period. While electroacupuncture versus applied relaxation, they both helped to promote HFs markedly but did not reveal statistically significance between them. Referring to Kupperman's index, all the treatment brought out great assistance when compared with baseline conditions, and there was significant difference between real acupuncture sham acupuncture (posttreatment: MD = -4.40, 95% CI: -6.77--2.03; follow-up: MD = -4.30, 95% CI: -6.52--2.08). In terms of OS, 7 prospective single arm studies focused on exploring the efficacy of traditional acupuncture, and all revealed moderate or great benefit for BC patients suffering from HFs. CONCLUSIONS: Acupuncture still appeared to be an efficacious therapeutic strategy, especially for the less/no side effects. Because of its widespread acceptance and encouraging effectiveness for improving HFs, much more high-quality studies are in need urgently.

[Study on photosynthesis and physiological characteristics of Acanthopanax giraldii on different light intensity].

This article is aimed to study the response mechanism of Acanthopanax giraldii on different shading intensity to guide its artificial cultivation. The cultivated A. giraldii in Maoxian was used as the research object, set up different shading treatment groups, analyzed photosynthesis, physiology, submicroscopic structure to explore the response mechanism of A. giraldii to different light intensity. Light was the main influencing factor to photosynthetic rate.During morning and afternoon periods,the Pn of the CK group reduced by stomatal limitation and non stomatal limitation factors respectively. While during 14：30-18：30 period, the Pn of A1 and A2 groups reduced by non stomatal limitation factors.LSP, LCP and Rd of A1 and A2 groups were significantly lower than those of CK group;The content of SS and SP of A1 and A2 groups were lower than those of CK group. The content of Pro of CK group were significantly higher than those of group A2.The activities of SOD and POD of them was higher than that of CK group,CAT activity of A1 and POD activity of A2 were relatively higher In their respective free radical scavenging system. Starch grain increased and base grana declined in the chloropalst of those group CK. The study results indicated that response mechanism of different shading conditions of A. giraldii under field cultivation conditions. Its could effectively adapt to environmental changes of the home cultivation,which provided a reference for ensuring yield and quality.

[Effect of pungent dispersion bitter purgation method on the esophageal mucosal intercellular space of reflux esophagitis model rats].

OBJECTIVE: To observe the effect of pungent dispersion bitter purgation method (PDBPM) on the esophageal mucosal intercellular space of reflux esophagitis (RE) model rats. METHODS: Totally 100 Wistar rats were randomly divided into the control group, the model group, the Western medicine group (WM), the Chinese medicine group (CM), 25 rats in each group. Rats in the control group only received switch operation. Rats in the rest three groups received modified partial cardia muscle incision combined pylorus ligation of external parts to prepare the RE rat model. Starting from the 3rd day after operation, WM mixture (Motilium 3. 2 mg/kg + Omeprazole Capsule 4.3 mg/kg + Hydrotalcite Tablet 161.4 mg/kg) was administered by gastrogavage to rats in the WM group. Rats in the CM group was administered by gastrogavage with Modified Banxia Xiexin Decoction (5.7 g/kg), 2.5 mL each time, twice daily for 14 consecutive days. Equal volume of normal saline was administered by gastrogavage to rats in the control group and the model group. On day 7 and 14, the lower esophagus pH value, general specimen of mucosa and histopathologic changes were observed. Intercellular spaces of esophageal epithelium were measured for a control study. RESULTS: Compared with the same group at day 7, the lower esophagus pH value increased at day 14 (P < 0.01); the naked eye integral of esophageal mucosa and intercellular spaces of esophageal epithelium also decreased at day 14 in the CM group and the WM group (P < 0.05). Compared with the control group at the same time point, the lower esophagus pH value decreased in the model group (P < 0.01). The naked eye integral of esophageal mucosa, and intercellular spaces of esophageal epithelium increased in the model group with increased intercellular spaces (P < 0.01). Compared with the model group at the same time point, the lower esophagus pH value increased and the naked eye integral of esophageal mucosa decreased in the CM group and the WM group at day 7 and 14 (P < 0.01). Intercellular spaces of esophageal epithelium of RE model rats at day 14 was lower in the CM group and the WM group than in the model group (P < 0.01). Compared with the WM group, the lower esophagus pH value decreased at day 7 in the CM group (P < 0.05); the naked eye integral of esophageal mucosa and intercellular spaces of esophageal epithelium decreased at day 14 in the CM group (P < 0.05). CONCLUSIONS: PDBPM had favorable treatment effect on RE model rats. The therapeutic effect was more obvious along with the therapeutic course went by. Its mechanism might be achieved through good repair effect on damaged mucosa, increasing the pressure of esophageal sphincter, and inhibiting gastric acid.

Efficacy and safety of tarcrolimus cream 0.1% in the treatment of vitiligo.

BACKGROUND: Vitiligo is an acquired, pigmentary skin disorder which is disfiguring and difficult to treat. Phototherapy and application of topical corticosteroids are most commonly prescribed. However, these therapies are often not effective and use of corticosteroids on the face may lead to cutaneous atrophy, telangiectasia, and ocular complications. OBJECTIVE: We sought to assess the efficacy of topical tacrolimus ointment in the treatment of vitiligo. METHODS: A prospective pilot study was performed of 30 patients with vitiligo. Patients were treated with tacrolimus ointment for at least 4 months. Clinical responses were documented during clinic visits, and by pretacrolimus and post-tacrolimus photography. RESULTS: Twenty-five (83.3%) patients showed some repigmentation at the end of 4 months. Patients with vitiligo for more than 5 years also responded well to tacrolimus ointment. Repigmentation in active vitiligo was superior to that in stable vitiligo. 80% of patients with segmental vitiligo of the head and neck showed some response to tacrolimus, but there was no statistical significance between segmental and vulgaris vitiligo. The mean percentage of repigmentation on the head and neck was greater than that on the trunk and extremities. Four patients initially experienced burning on application. CONCLUSIONS: Topical tacrolimus ointment is an effective and well-tolerated alternative therapy for vitiligo especially involving the head and neck.

[Antitumour effect of total saponins of Rubus parvifolius on malignant melanoma].

OBJECTIVE: To evaluate the antitumor effect of total saponins of R. parvifolius on malignant melanoma. METHOD: The human malignant melanoma A375 cells were regularlly subcultured in vitro, and were divided into five groups contained positive control group (CTX), high concentration (0.01 mg x mL(-1)) and middle concentration (0.001 mg x mL(-1)) and low concentration (0.000 1 mg x mL(-1)) total saponins of R. parvifolius groups and negative control group. By using MTT colorimetric method, the cell viability was measured. B16 melanoma cells were transplanted to mice, which were divided into positive control group, high dose (100 mg x kg(-1)) and middle dose (50 mg x kg(-1)) and low dose (25 mg x kg(-1)) total saponins of R. parvifolius groups and negative control group. The inhibition effect of the tumor in vivo, mean survival time and rate of life-elongation of the mice were observed. TUNEL method was used to detect the apoptosis of B16 malignant melanoma. RESULT: Antitumor assay in vitro showed that the absorbency increased in the concentration of 0.01, 0.001 mg x mL(-1) with statistical significance (P < 0.05 vs negative control). Antitumor assay in vivo showed that the tumor inhibitory rate of high dose (100 mg x kg(-1)) and middle dose (50 mg x kg(-1)) of total saponins of R. parvifolius were 37.02% and 30.61%, respectively. Loaded tumor mouse survival duration could be prolonged. The apoptosis indexes of B16 tumor cells in three treatment groups were 32.5%, 20.5% and 5.5%, respective and there was statistical significance (P < 0.05 vs negative control). CONCLUSION: The total saponins of R. parvifolius has remarkable inhibition of proliferation of malignant melanoma cells in vivo and in vitro and exerts antitumor activities through promoting tumor cell apoptosis.
