ObjectiveTo investigate the effect of Puerarin on expression of inductible nitric oxide synthase (iNOS) in RAW264.7 macrophage cells induced by lipopolysaccharide （LPS）. MethodsThe protein and mRNA levels of lipopolysaccharide (LPS)-induced iNOS was determined in RAW264.7 macrophage cells using Western blotting and RT-PCR respectively. ResultsPuerarin inhibited expression of iNOS concentration dependently (P<0.01). ConclusionPuerarin may reduce iNOS level, result in prevention of inflammation.

Objective:To evaluate the effect of short-time group psychological guidance on mental quality of college students. Methods:Designed the content of one day's psychological coach.600 college students received psychological coach successively.60 students were randomly chosen as the intervened group,who were treated with one-day group psychological guidance,while 60 students,who never attended the group psychological guidance,were chosen as control.Assessed and compared the mental quality of the intervened group and the control group with the Faith in People Scale (FPS),Personal Evaluation Inventory (PEI),Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale (SDS) on the day before or 1 and 12 weeks after coach.Results:There were no significant differences of the scale of FPS,PEI,SAS,and SDS between two groups before coach and there were significant differences between two groups after coach.Conclusion:Short-time group guidance is helpful to developing college students' ability in interpersonal contact and self-confidence and improving depression and anxiety.

Objective To study the differences in retinoic acid receptor γ(RARγ) mRNA expression levels in blood leukocytes between antipsychotic-free and antipsychotic-naive schizophrenic patients and healthy control,especially in different genders. Methods Forty-three acute schizophrenic patients who were antipsychotic-naive or antipsychotic-free for at least three months (male = 34, female = 9) and 39 age- and sex-matched healthy subjects (male =25 ,female = 14) were included for blood leukocytes expression of RAR γ mRNA ,using real-time PCR technique. Results Kolmogorov-Smirnov Z analysis showed a significant increase of RARγ mRNA (P =0.041) level in blood leukocytes of pooled schizophrenic patients(0. 027 ± 0. 003) than in the healthy subjects (0. 020 ± 0.002). The elevation was mainly found in the female patients (0. 030 ± 0.003). Within-sex analysis showed that the female schizophrenic patients showed a trend increase (P = 0. 166) of RAR γmRNA expression compared with the male patients (0. 026 ± 0. 001) and exhibited greater RARγ mRNA expression (P = 0. 014)when compared with the female healthy subjects(0. 018 ±0.004). Conclusions The present findings showed an abnormal expression of leukocyte RARγ mRNA level in antipsychotic-free and antipsychotic-naive schizophrenia especially in the female patients. Blood RARγ markers could add to the diagnosis and individualized pharmacotherapy of schizophrenic patients ,especially the female patients.

Objective To evaluate the effect of triamcinolone orbital injection combined with dexamethasone in treatment of the patients with the grade Ⅳ of thyriod associated ophthalmopathy. Methods NOSPEVS Ⅳ grade of 90 patients were randomly divided into three groups,Group A,orbital injection of triamcinolone combind with dexamethasone, Croup B,simple injection of triamcinolone,Group C,oral prednisone therapy for half a year. To review each record of visual acuity intraocular pressure palpebral fissure size, upper eyelid drop late exophthalmos eye movement and so on every 4 weeks and follow-up for one year. Results Group A and group B of exophthalmos and eye movement improved obviously,however,Group C with poor efficacy and more side effects,and Group A in 3 groups was the fastest with least number of injections and which improved eye symptons significantly with fewer complications. Conclusion Orbital injection of triamcinolone combined with dexamethasone could be more rapid and effective than a simple injection of triamcinolone or oral prednisone to improve symptoms and signs in thyroid ophthalmopathy.

Objective To investigate the clinical value of 99Tcm-MIBI gated G-MPI in detecting the myocardial damage in sarcoglycanopathy.Methods 99 Tcm - MIBI G - MPI was performed in 8 patients (3 males,5 females,age ranged from 10 to 30 y) with sarcoglycanopathy confirmed by clinical results and molecular pathology and 4 healthy persons as control group.Quantitative gated SPECT (QGS) software was used for processing and interpretation.Myocardium of left ventricle was divided into 7 segments and 20 subsegments.A five-point scoring system was used to evaluate the myocardial damage.Results Seven patients showed positive results in G-MPI (7/8).Fifty-nine sub-segments of injured myocardium were detected in the 140 sub-segments of 7 abnormal patients.One abnormal segment was observed in 1 patient,two abnormal segments were detected in 2 patients,and ≥3 abnormal segments were observed in 4 patients.Enlarged left ventricles were detected in 5 patients (5/8),and the LVEF of 3 patients among them decreased to (43.1 ±2.8)％.Conclusion 99Tcm-MIBI G-MPI can detect myocardial damage in sarcoglycanopathy as a direct and non-invasive method,and can be used in the early diagnosis and long-term follow-up in sarcoglycanopathy.

Background Diabetic complication is associated with lipid peroxidation.Aldehyde dehydrogenases (ALDH) catalyze the irreversible oxidation of a variety of biological aldehydes,including lipid-derived aldehydes (LDAs),and thus protect organs and tissues from toxic LDAs.Understanding the activity of ALDH in different ocular tissues in diabetic subjects is very important for prevention and treatment of diabetic ocular complications.Objective This research aimed to investigate the activity and expression of ALDH in different ocular tissues in diabetic rats and to explore the mechanism of ALDH in diabetes-induced eye disease.Methods Twenty-eight healthy SPF male Sprague-Dawley(SD) rats weighted 170-180 g were randomly divided into the normal control group and diabetic group.The diabetic animal model was established by intraperitonial injection of 4％ streptozotocin at 65 mg/kg.Isometric citric acid buffer was injected in the rats of the normal control group.The rats were sacrificed in each group 2 and 4 months after the establishment of the diabetic models,and eyeballs were obtained for the preparation of corneal,lens and retinal homogenates.ALDH activity was detected using a multifunctional microplate reader SpectraMax M5,and ALDH content was measured by ELISA at the wavelength of 450 nm with the SpectraMax M5 ELISA reader.Results The blood glucose level in diabetic rats was significantly elevated at various time points compared with the normal control group(P=0.000),and body weights were evidently lower in the diabetic group than in the normal group (P =0.000).The activities of ALDH (A340) in corneal,lens and retinal tissues in the diabetic group were increased in comparison with the normal control group (F =396.601,P=0.000),and showed an enhancement with the lapsing of time (F =53.139,P =0.000).In addition,the highest level of ALDH was found in the cornea and the lowest level in the lens(F =6973.000,P=0.000).The expression level of ALDH in the corneal,lens and retinal homogenates was significantly higher in the diabetic group compared with the normal control group (F=312.985,P =0.000) and showed a considerable increase over the course (F =19.203,P=0.000).The highest expression level was seen in the cornea and the lowest was in the lens,with a significant difference among these three kinds of tissues (F =3243.000,P =0.000).Conclusions ALDH can protect ocular tissue from the damage of lipid peroxidation.Thess results suggest that ALDH plays a role in preventing diabetes-related ocular complications.

Objective To investigate perioperative antimicrobial prophylaxis in thyroid operation at all levels of hospitals in a province.Methods From January 1 ,2011 to December 31 ,2013,all kinds of thyroid operation in a province were conducted targeted monitor,investigated results were analyzed.Results A total of 1 304 cases of thy-roid operation were investigated,1 294 (99.23%)were elective operation;duration of operation of 1 051 cases (80.60%)were ≤2 hours;antimicrobial use rate was 96.70%;196 patients (15.45%)were administered 30 mi-nutes before operation,887 patients (70.34%)used antimicrobial agents for >48 hours;19.53% of patients used the first generation cephalosporins and clindamycin.Conclusion There are some problems in antimicrobial use in thyroid operation in this province,such as inappropriate choice of antimicrobial agents,improper administration time,long time use of antimicrobial agents,and use antimicrobial agents without indications.Management of anti-microbial agents should be strengthened,so as to promote the rational use of antimicrobial agents.
