Objective To explore the clinical efficacy of back acupoint pricking and cupping combined with intense pulsed light in the treatment of acne vulgaris.MethodsTotally 160 cases of acne vulgaris treated in our hospital from July 2014 to August 2015 were selected and randomly divided into observation group and control group, 80 cases in each group. Patients in both groups were treated with intense pulsed light, every two weeks, for 4 times. Patients in the observation group were treated with back acupoint pricking and cupping based on the treatment above, every other day, five times as a treatment session, for two sessions. The treatment efficacy was compared between the two groups.ResultsThe total effective rate in the observation group was 96.25% (77/80), which was significantly higher than 77.50% (62/80) in the control group, with statistical significance (P<0.01). Serum T of the two groups after the treatment decreased significantly when compared with those before the treatment. Serum T in the observation group in patients of the same sex decreased significantly after the treatment compared with those in the control group (P<0.01). Total scores of self-perception, emotion function and Qol-Acne score after treatment in observation group were significantly higher than those in the control group (P<0.01). After 3 months of treatment, the recurrence rate of the effective patients in the observation group was 2.60% (2/77), lower than the control group, which was 16.13% (10/62) with significant difference (P<0.01).Conclusion The clinical efficacy of back acupoints pricking and cupping combined with intense pulsed light in the treatment of acne vulgaris is confirmative, which can effectively reduce androgen levels and improve the life quality of patients, with low recurrence rate.

OBJECTIVE:To observe the efficacy of Ruzengxiao in the prevention and cure of hyperplasia of mammary glands in rats.METHODS:To investigate the therapeutic effect of drugs,the spayed rats were injected i.m with benzoic acid E2 0.8mg? kg-1 qd alt for 90 consecutive days,during the period between 20 and 30 days after modeling,these rats were injected with progesterone 4mg? kg-1 qd alt for 5 consecutive times;30d after modeling,the model animals with hyperplasia of mammary glands were randomized to groups to be treated intragastrically with 0.05% CMC-Na,Ruzengxiao or Tomoxi fen qd for 60d consecutively.Samples were taken at 24h after the last time of drug administration for determination of indexes.RESULTS:After treating the model animals for 2months,the following experimental results were obtained:for the spayed animals,after injection with estradiol(E2)for 3mo,their index of thymus decreased,indexes of uterus and adrenal glands increased significantly;levels of estrogen receptor(ER)in mammary tissues and serum E2 increased significantly,while the serum progesterone(P)deceased significantly,ratio of E2/testosterone(T)increased significantly;the numbers of lobules of mammary gland increased,hyperplasia of interstitial tissues appeared,secretion of acini increased,and the acini were highly distended,level of prolactin(PRL)increased,while levels of luteinizing hormone(LH)and follicle stimulating hormone(FSH)decreased,but no statistic difference was noted as compared with castration group(spayed animal without administration with E2 and P etc.);the E2-induced increase in indexes of uterus and adrenal gland was significantly inhibited after treatment with Tamoxifen or Ruzengxiao 20g? kg-1 for 2mo;Both Ruzengxiao(at different dosage)and Tomoxifen could significantly increase serum Testosterone level but decrease ratio of E2/T in rats with hyperplasia of mammary glands,showing significant differences as compared with model group.All drugs showed no obvious effect on serum levels of LH,FSH,PRL,P and E2 etc in rats with hyperplasia of mammary glands.CONCLUSION:The above results reveal that Ruzengxiao has satisfactory preventive and curative effects on model rats with hyperplasia of mammary glands.This mechanism might be related to the reduction of serum levels of E2,P and PRL,and the ratio of E2/T.

Objective To study the expressions of TLR4, CD14, MD-2 and NF-kB in colonic mucosa in patients with diarrhea-irritable bowel syndrome (IBS-D) , and compared with normal subjects. The purpose of this study is to explore the role of TLR4 and TLR4 signal transduction pathway in the pathogenesis of IBS-D. Methods The expressions of TLR4, CD14, MD-2 and NF-kB in colon mucosa were examined by immunohistochemistry (IHC) in 30 IBS-D patients and 12 healthy volunteers separately. The average absorbance (A value) of TLR4 was analyzed. The positive expression rates of CD14, MD-2 and NF-kB of colonic mucosa were studied. Results Compared with healthy controls, significant upregulation of TLR4 expression relative to controls was found in colon mucosa of IBS-D. A value of TLR4 in IBS-D was significantly higher (0.3971 ±0.0996 vs 0. 3044 ±0.0481). The positive rate and intensity of NF-kB in IBS-D were significantly higher than those in healthy. The number of positive cells of MD-2 showed significant increase in lamina propria of IBS-D against controls. The percent of CD14 positive was upregulated in lamina propria in IBS-D. The expressions of MD-2 and CD14 in intestine epithelial cell were low or negative. Conclusions There is the activation of the signal transduction pathway of TLR4/NF-kB in the colonic mucosa of patients with IBS-D. Up-regulated expression of TLR4 in IBS patients suppose that it might contribute to occurrence of IBS-D.

Objective To study the expressions of Toll-like receptor (TLR)2 and TLR4 in colonic mucosa of patients with irritable bowel syndrome (IBS) and in normal subjects. Methods Thirty patients with diarrhea predominant IBS and 12 healthy volunteers were enrolled. The expressions of TLR2 and TLR4 in colonic mucosa were examined by immunohistochemistry (IHC).TLR2 and TLR4 were semi-quantitative analyzed with average absorbence. Results Contrast to healthy controls, the lamina propria of IBS patients showed edema and looseness with lots of inflammatory cells infiltration. There was no difference in expression of TLR2 between healthy controls and IBS patients (P>0.05). Compared with healthy controls, TLR2 in crypt epithelium and TLR4 in luminal surface of IBS patients were significantly up-regulated (TLR2 : 6.7 % vs. 50.0 %,TLR4: 40.0% vs. 0, P<0. 05). The TLR4 expressed in intestine epithelial cell of both the apical surface and the basolateral surface in 86.7% of patients with IBS, and in 50% of healthy controls.The positive cells of TLR4 in lamina propria were higher in patients with IBS than those in healthy controls (70. 084 ± 21. 887 vs. 20. 577 ± 4. 546, P<0.01). The A values of TLR2 and TLR4 in colonic mucosa of the patients with IBS were higher than those in healthy controls (TLR2:0. 3079±0. 0283vs. 0.3886±0. 0510,TLR4:0. 3044±0. 0481 vs. 0. 3971 ±:010996,P<0. 01). Conclusions Inflammatory cells infiltrated into colonic mueosa in patients with IBS suggested that inflammation might participate in the pathogenesis of IBS. Up-regulated expressions of TLR2 and TLR4 in IBS patients supposed that they might contribute to the occurrence of IBS.
