Objective To examine the relationship among gratitude,coping styles,and pathological Internet use (PIU) in secondary vocational school students.Method 1 011 secondary vocational school students were tested with gratitude questionnaire,coping style questionnaire and pathological internet use questionnaire.Results The scores of gratitude,problem-solving,help-seeking,guilty,illusion,withdrawal,rationalization and PIU were respectively (5.23 ± 1.06),(0.65± 0.21),(0.50± 0.22),(0.40± 0.23),(0.47 ±0.22),(0.51 ±0.18),(0.42±0.18),(2.23±0.97).Gratitude was significantly and negatively associated with PIU(r=-0.18,P＜0.01).Moreover,the effect of gratitude on PIU was totally mediated by problem-solving,guilty,illusion,and rationalization (27.27％,33.43％,29.72％,9.58％).However,the mediating effects of help-seeking and withdrawal were not significant.Conclusion Coping styles mediate gratitude and PIU,and coping styles should be considered during pathological internet use of secondary vocational school students.

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 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 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.

Ribosome inactivating protein(RIP) is a kind of toxin plant pr ot ein in which extensively lives in the body of higher plants and controls ribosom e's function. Beside it can control protein's combination,it has lots of biolog ical reactivity as resisting giving birth and tumor and controlling HIV. At fir st, RIP is isolated from seeds of bitter melon.The result of SDS-PAGE indicate s that there are lots of RIP in the abstraction liquid.Then we study the antivi ral action of RIP through the cell of CEF and SPF chicken embryos.The results s how that RIP can resist NDVF_48E_8,MDVCVI_988 and FPV-SD4 to so me extent.

OBJECTIVE To investigate the positive rate of ?-lactamase,oprD2,aminoglycosides modifying enzyme and qacE△1 gene among clinical isolated strains of multi-resistant Pseudomonas aeruginosa in our hospital.METHODS P.aeruginosa was determined by VITEK,and MIC was determined by agar dilution method.TEM,IMP,VIM,oprD2,aac(3)-Ⅱ,aac(6′)-Ⅰ,aac(6″)-Ⅱ,ant(3″)-Ⅰ,ant(2″)Ⅰ and qacE△1 in strains were detected by polymerase chain reaction(PCR).RESULTS The positive rate of TEM,aac(3)Ⅱ,aac(6′)-Ⅱ,ant(3″)-Ⅰ and ant(2″)-Ⅰ in multi-resistant P.aeruginosa were 51.4%,48.6%,40.0%,54.3%,45.7% and 60.0%,respectively.No IMP and VIM genes were detected.CONCLUSIONS Positive rate of ?-lactamase, aminoglycosides modifying enzyme is high in 35 tested strains,and that should be paid more attention.

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.
