Objective Acne vulgaris remains a major problem in dermatological practice. Phototherapy for acne with blue and red light-emitting diode (LED) arrays has recently attracted attention.The aim of this study is to observe the clinical effect of the blue and red light combination phototherapy on acne. Methods 65 individuals were recruited: 25 females and 5 males. Patients underwent treatment of 20-25 minutes blue light and 5-10 minutes combined light treatment twice per week. Continuous irradiation for 4 weeks was as 1 session. Mild acne vulgaris was treated for 1 session, moderate and severe acne were treated for 1 or 2 sessions. Results After system treatment, the acne lesion was reduced apparently without side effect. The effective rate of mild acne vulgaris, moderate acne vulgaris and severe acne vulgris was 80 %, 89.4 % and 88.2 %, respectively. Conclusion The combination of blue and red light-emitting diode therapy for acne vulgaris is effective. This therapy is convenient without side effect, and it is a new preferable modality for the treatment of acne.

Objective To investigate the expression of VEGF-D and MMP-2 and explore their relationship with tumor invasion and local metastasis in pancreatic carcinoma.Methods The expression of VEGF-D and MMP-2 in 30 patients with pancreatic carcinomas and 6 cases with normal pancreatic tissues were detected by SABC immunohistochemical method.Results The positive rates of VEGF-D and MMP-2 proteins were 60%(18/30)and 66.7%(20/30)respectively,no expression of VEGF-D and MMP-2 was detected in normal pancreatie tissues.The expression of VEGF-D was significantly correlated with lymph node metastasis(P<0.05),and the expression of MMP-2 was significantly correlated with lymph node metastasis and tumor local invasion(P<0.05).The expression of VEGF-D protein Was positively correlated with MMP-2 protein(rs=0.54,P<0.01).Conclusions There is a significantly positive correlation between high expression of VEGF-D and MMP-2 proteins in pancreatic carcinoma,and they may contribute to the invasive properties of pancreatic cancer.

OBJECTIVE:Using in vitro studies,we evaluated the antibacterial activity of amoxicillin/tazobactam against 128 strains of pathogens isolated from patients and compared with amoxicillin/clavulanic acid and amoxicillin/sulbactam.METHODS:To detect the minimum inhibitory concentrations (MIC)of four ?-lactams against 128 clinically isolated strains with agar dilution method.RESULTS:The results indicated that the in vitro antibacterial activity of amoxicillin/tazobactam(2∶1) was the best.The MIC50 of amoxicillin/tazobactam(2∶1) is 1/4~1/8 times than those of amoxicillin/sulbutam and amoxicillin/clavulanic acid.The MIC90 of amoxicillin/tazobactam(2∶1) was 1/2~1/4 of those of amoxicillin/sulbutam and amoxicillin/clavulanic acid.The combination ratio 2∶1(amoxicillin/tazobactam)of the two compounds was more suitable than other combination ratios(4∶1 and 8∶1)for inactivating ?-lactamase.CONCLUSION:The in vitro antibacterial activities of amoxicillin/tazobactam(2∶1) against MRSA,MRSE,MSSA and E.coli are high.It showed that amoxicillin/tazobactam(2∶1)is stable to ?-lactamase and is an effective bactericidal agent.

Objective To observe the effects of electroacupuncture at Ganshu (BL18) and Zusanli (ST36) on depression state and gastrointestinal motility and relevant protein expressions in brain of rats with stress-induced depressive functional dyspepsia. Methods Totally 48 Wistar rats were randomly divided into normal, model, electroacupuncture (EA) and sham-operation group, with 12 rats in each group. Depressive functional dyspepsia model was established by chronic unpredictable mild stress protocols. From day 15 to day 28, the EA group was given electroacupuncture at BL18 and ST36, and the sham-operation group was stimulated by electroacupuncture at 1/3 and 2/3 of the tail. Body weight test, open field test and sucrose preference test were measured on day 0, day 14 and day 28. After 14-day administration, gastric residual volume and intestinal propulsion rate of semisolid paste were detected. The expression of βCaMK inⅡ lateral habenulas and BDNF in hippocampus were measured by Western blot. Results Compared with the normal group, the weight, the sucrose preference rate, the behavior score, the small intestinal propulsion rate of semisolid paste and the expression of BDNF in hippocampus decreased significantly both in the model group and sham-operation group (P<0.01), and the gastric residual volume of semisolid paste and the expression of βCaMK inⅡ lateral habenulas increased significantly (P<0.01). Compared with the model group, the weight, the sucrose preference rate, the behavior score, the small intestinal propulsion rate of semisolid paste and the expression of BDNF in hippocampus increased significantly in EA group (P<0.01), and the gastric residual volume of semisolid paste and the expression of βCaMK inⅡ lateral habenulas decreased significantly (P<0.01). Compared with the sham-operation group, the expression of βCaMKⅡ in lateral habenulas decreased significantly, the expression of BDNF in hippocampus increased significantly in EA group (P<0.01). Conclusion Electroacupuncture at Ganshu (BL18) and Zusanli (ST36) can improve depression and gastrointestinal motility of rats with depressive functional dyspepsia, which may be related to the inhibition of βCaMK inⅡ lateral habenulas and the activation of BDNF in hippocampus dyspepsia.

ObjectiveTo investigate the correlation between ineffective esophageal motility (IEM)and gastroesophageal reflux disease (GERD).MethodsA total of 90 GERD patients were enrolled in our study,including 62 patients with reflux esophagitis (RE) and 28 with non-erosive reflux disease (NERD).All the patients underwent gastroscopy,24-hour esophageal pH monitoring and esophageal manometry.ResultsIn the RE group 30 (48.4%) patients were diagnosed as having IEM,which was significantly higher than the NERD group (6 patients,21.4% ) (P<0.05).Positive esophageal acid exposure was more often seen in patients with IEM than in those with normal esophageal motility (91.7% v.s.57.2%,P <0.01 ).The values of total percentage of time with pH <4,percentage of reflux time in supine position,long-duration episodes ( >5 min) and the longest reflux time and DeMeester score were significantly higher in the IEM cases than those in the normal esophageal motility cases ( P < 0.01 ),so was the values of number of reflux episodes (P < 0.05).ConclusionIEM is the most common esophageal dysmotility in patients with GERD and closely related to distal esophageal acid exposure and RE.
