Objective To investigate the relationship between interleukin-17 (IL-17) and vitiligo.Methods Totally,32 vitiligo patients and 30 healthy human controls were enrolled in this study.Blood samples were collected from all the subjects,and enzyme-linked immunosorbent assay (ELISA) was performed to determine the plasma levels of IL-17.The relationship of plasma IL-17 levels with disease stage,clinical course and lesion area was assessed.Results The plasma levels of IL-17 were significantly higher in the patients with progressive and stable vitiligo than in the healthy controls (both P ＜ 0.05),and higher in the patients with progressive vitiligo than in those with stable vitiligo (P ＜ 0.05).Moreover,the plasma levels of IL-17 were positively correlated with the area of vitiligo lesions (r =0.456,P ＜ 0.05),but unrelated to the clinical course of vitiligo (r =0.239,P ＞ 0.05).Conclusion IL-17 may play a certain role in the occurrence and development of vitiligo.

Objective To compare the clinical efficacy of acupuncture and medicine for the treatment of chronic pharyngitis. Methods Sixty chronic pharyngitis patients were randomized into treatment group and control group, 30 cases in each group. The treatment group was treated with acupuncture mainly on acupoints of Zhaohai(KI6), Lieque(L7), Tiantu(CV22) , Lianquan(CV23), Tianrong(SI17) , Hegu(LI), Yuji (LU10) for nourishing yin to reduce fire and clearing throat. The supplementary acupoints were selected according to the symptoms and physical signs. Acupuncture was performed once a day and 6 times a week. The control group received western medical therapy including pharyngeal application with 1% iodine glycerin preparation and oral use of Cydiodine tablets, 3 times per day. Four weeks constituted one treatment course and the treatment for the two groups covered 2 courses. After treatment, the therapeutic effect was evaluated. The scores of the signs and s ymptoms as well as scores of chronic pharyngitis syndrome discomfort rating questionnaire(CPSDQ) evaluated by visual anal og scale(VAS) were observed. Results (1) The overall effective rate of the treatment group was 93.3%, higher than that of the control group(73.3%), and the inter-group difference was statistically significant (P<0.05). (2) After treatment, scores of the signs and symptoms and VAS for CPSDQ scores in the two groups were reduced as compared with those before treatment(all P<0.05 or P<0.01 ) .The improvement of the scores in the treatment group was superior to that in the control group(all P<0.05 or P<0.01).(3) During the treatment , needling-induced mild pain and bleeding occurred in the treatment group. No acupuncture syncope, stuck needles or allergic and toxic-side effect was shown in the two groups. Conclusion Acupuncture therapy can obviously relieve the symptoms, signs and discomfort in the patients with chronic pharyngitis, and the curative effect is superior to the drugs.

Objective To describe the clinical and imaging manifestations of patients with synovitis acne pustulosis hyperostosis osteomyelitis (SAPHO) syndrome,and to analyze the diagnostic importance of different clinical and imaging manifestations for SAPHO syndrome. Methods Seventeen patients (7 males and 10 females) with SAPHO syndrome were recruited in this study.Age ranged from 36 to 67 years with a mean age of (48 ± 8) years. All patients fulfilled the diagnostic criteria of Benhamou. Serum HLA B27 antigen records were reviewed for all patients. Imaging data of the abnormal bone sites were collected by conventional radiograph in all patients,CT in 13 patients as well as MR in 3 patients.Average time to take for a definite diagnosis of the syndrome was 3.7 years (ranged from O.5 to 13 years).Results Serum HLA B27 antigen was positive in all patients. Both skin and bone abnornalities were found in all patients.Ten patients had skin palmoplantar pustulosis and two patients had acne. Involving sites of bone and joints include sacroiliac joints,anterior chest and limbs.Sacroiliac joints were asymmetrically involved with imaging features in all patients.Eight patients exhibited anterior chest wall involvement. Five patients had osteomyelitis at limbs. For all images of 17 patients,CT was superior to conventional radiography in detecting abnormal changes of bone erosion and soft tissue swelling.MR imaging was able to depict edema changes that was not detectable by CT and radiography.Conclusion SAPHO syndrome is a rare disease,but for patients with skin and bone-joint abnormalities,especially with skin palmoplantar pustulosis,acne as well as with imaging features at the sacroiliac joint and anterior chest wall,SAPHO syndrome should be taken into a diagnostic consideration.

Objective To investigate the effect of homeopathic reduction technique in treatment of irreducible variant femoral neck fractures.Methods A retrospective case control study was performed for 91 cases of irreducible variant femoral neck fractures surgically treated from January 2011 to January 2014.Forty-seven cases [31 males,16 females;23-61 years,mean 40.6 years] were assigned to homeopathic reduction treatment (study group) and 44 [30 males,14 females;28-63 years,mean 43.1 years] were assigned to closed reduction and open reduction (control group).All fractures were Garden type Ⅳ.All cases were stabilized with three cannulated screws (6.5 mm in diameter).Operation time,intraoperative blood loss,Garden index for reduction quality,bone healing,complications like femoral head necrosis and Harris hip score were evaluated.Results Operation time and blood loss in study group [(41.2 ± 7.5) min,(37.3 ± 9.5) ml] were significantly lower than those in control group [(105.0 ± 15.7) min,(269.6 ± 50.6) ml] (P ＜ 0.05).Garden index was Grade Ⅰ 44 cases and Grade Ⅱ three in study group compared to Grade Ⅰ 20 and Grade Ⅱ three in control group (P ＜ 0.05).Incidence of femoral head necrosis had no significant differences between study group (four cases) and control group (10 cases) (P ＞ 0.05).Nonunion was not observed in study group,while there were eight cases of nonunion in control group (P ＜ 0.05).According to the Harris score,the excellent rate in study group was 91％ (39 excellent,four good,four fair) versus 66％ (21 excellent,eight good,15 fair) in control group (P ＜ 0.05).Conclusion Compared to closed reduction and open reduction,homeopathic reduction technique in treatment of femoral neck fractures is associated with shortened operation time,reduced blood loss,improved reduction quality and lowered incidence of necrosis and nonunion.

MIC.RESULTS The bacteriostatic/bactericidal CFR of 0.5g q8h imipenem/cilastatin and 0.5g q8h meropenem were the highest(100%);that of 3.375g q4h sodium piperacillin/tazobactam sodium against ESBLs-producing E.coli was above 90%;the CFRs of ceftriaxone(1g q24h,2g q24h),ceftazidime(1g q8h,2g q8h),cefepime(1g q8h,1g q12h,2g q8h) and cefoperazone sodium/sulbactam(0.5g q8h,1g q8h,2g q8h) against ESBLs-producing strains were clearly less than those of non-ESBLs-producing ones,and the CFRs could not be effectively improved with the dose and frequency increased.CONCLUSIONS The PK/PD simulation is useful to optimize the regimen of anti-infective treatment,and guide its dosing accurately.
