Objective: To evaluate the reliability and validity of the Chinese version of Frost's Multidimensional Perfectionism Scale(FMPS).Methods: One thousand two hundred and eighty Chinese undergraduate students participated in the study and responded to the FMPS and instruments measuring psychological distresses such as anxiety,depression,and obsession-compulsion.Both exploratory and confirmatory factor analyses were used to examine the factor structure of the Chinese FMPS.The association between FMPS and psychological distresses was analyzed as an investigation for criterion validity.Results: Factor analyses extracted five of the original six factors of FMPS.PC did not emerge as a dimension.The five subscales were shown to have satisfactory internal consistencies with Cronbach's alpha between 0.64 and 0.81 and test-retest reliability 0.63~0.82.Chinese FMPS was associated with anxiety,depression,and obsession-compulsion.Particularly,CM and DA are correlated with these psychological distresses with coefficients between 0.30 and 0.70.Conclusion: Chinese FMPS is satisfactorily valid and reliable.It is suitable to use in Chinese college students.

Objective To explore the effects of behavioral inhibition system/activation system (BIS/BAS) and emotion regulations on depression of adolescents.Methods 800 adolescents from an university and a middle school were chosen by cluster random sampling,and were surveyed by BIS/BAS scale,Beck depression inventory(BDI),center for epidemiologic studies depression scale (CESD) and cognitive emotion regulation questionnaire (CERQ).The data were analyzed by pearson correlation,F test and multiple stepwise regression analysis.Results (1) BDI and CESD were correlated positively with BIS (r =0.39,0.41,P ＜ 0.01),self-blame,rumination,catastrophizing,blame others and perspective(r =0.19-0.50,P ＜ 0.05-0.01),and negatively with planning,reappraisal (r =-0.08-0.24,P＜0.05).(2)The scores of severe depression group were highest(15.45 ±2.57,P＜0.01) in BIS,lowest in BAS-drive(9.60 ±2.99,P＜0.01),and nonadaptive emotion regulations were used mostly,and adaptive emotion regulations were done leastly.(3) Catastrophizing,BIS,reappraisal,rumination,refocusing and self-blame explained 35％ of total variance,and catastrophizing and BIS explained the largest proportion,respectively 25％ and 4％.Conclusion BIS/BAS and emotion regulations may be important factors influencing non-clinical depression of adolescents.

Objective To explore the clinical manifestations of toxic epidermal necrolysis(TEN) and its rare pulmonary complications.Methods Clinical symptoms,treatment and prognosis of 1 child with TEN caused by carbamazepine were analyzed.Radiological images were reviewed to evaluate the manifestations and the outcome of chronic pulmonary complications associated with TEN.Results The patient had high fever shortly after a dosage increment of carbamazepine.A confluent erythematous exanthema developed rapidly into painful blistering with skin erosion,denudation and involvement of conjunctive and oropharyngeal mucosa.The diagnosis of TEN was made.The mucocutaneous damage was gradually recovered with steroid plus intravenous immunoglobulin for 3 weeks.However,the patient presented with respiratory failure in the recovery phase of TEN.The computer tomography revealed pulmonary bullae and pneumothorax in the right lung.Lung parenchyma was squeezed and pulmonary bullae ruptured with pneumothorax and atelectasis,which were absorbed gradually through thoracic drainages.The patient′s lung function and pulmonary bullae were partly improved during a 7-month follow-up.Conclusions TEN is a severe form of blistering skin di-sease which is characterized by an extensive loss of epidermis and mucous membrane.Chronic pulmonary complications may occur in recovery phase of TEN.Pulmonary bullae,which might be caused by mucous damage and respiratory obstruction,is a rare complication of TEN.

Abstract?AIM:To investigate the clinical effect of orthokeratology for 400 juvenile with myopia astigmatism and its effects on corneal endothelial cells.?METHODS:Four hundred patients(800 eyes), of whom the average age was 11.5 ±2.3 years old, 239 male, 161 female, were divided into two groups: orthokeratology group and spectacles group. Parameters including efficacy data ( uncorrected visual acuity, corneal curvature, axial length and diopter ) and corneal endothelial cell data ( count of endothelial cell, endothelial cell density, fluorescein staining and central corneal thickness) were observed at 1d, 1, 6, 12 and 24mo after wearing.? RESULTS: The visual acuity of spectacles group recovered to normal after wearing, that of orthokeratology group recovered to normal at 1mo after wearing.At 2a after wearing, the corneal curvature, diopter of orthokeratology group decreased significantly (40.09 ±0.31D, 0.23 ±0.06D respectively); while those of spectacles group increased, the differences between the two groups were significant (P<0.05).The axial length of the two groups increased slightly at 1mo after wearing ( P>0.05 ) compared to those before wearing. At 2a after wearing, the axial length of the two groups were 23.96 ± 0.38mm, 26.49±0.88mm respectively (P<0.05).At 2a after wearing, central corneal thickness was 527.33 ± 27.69mm, 526.98±26.89μm(P>0.05).The count of endothelial cell and endothelial cell density both decreased after wearing without significant differences (P>0.05).?CONCLUSION: Orthokeratology has less effect on the corneal endothelial cells, no obvious adverse reactions and can control the prognosis of myopia.

The fermentation conditions which affect C-15? hydroxylation o f 18-methyl-estr- 4-ene-3,17-dione were investigated. As the key step in the Hydroxylation, the dissolution of substrate was focused on. Tween80, MeOH, DMSO,?-CD and 2-HP?CD were studied to improve the dissolvability of 18-met hyl-estr-4-ene-3,17-dione.The other factors such as pH, substrate concent ration and aeration strategies which affected conversion rate were also resea rched. As a result, the conversion rate can be up to 60% in shake flask and ach i(eve 50% in fermentor,which would overcome the disadvantage of 15?-hydroxyl -18-methyl-estr-4-ene-3,17-dione chemosynthesis and provide a good techn ics to industry.

OBJECTIVE:To study the effects of Shenfu qiangxin(SFQX)pills on the expression of autophagy-associated pro-tein LC3b and pro apoptotic gene Bax in myocardial cells of rats with cardiorenal syndrome (CRS). METHODS:Rats were ran-domly divided into sham operation group(water),model group(water),positive control group(Captopril tablets 2.3 mg/kg)and SFQX pills high-dose,medium-dose and low-dose groups [13.2,6.6,3.3 g(crude drug)/kg],with 10 rats in each group. CRS mod-el was induced in those groups by abdominal-aortae-constriction+acute renal ischemia reperfusion injury except for sham operation group;and they were given relevant medicine intragastrically 8 week after operation,once a day,for consecutive 4 weeks. Plasma contents of Cr and ALD,the protein expression of LC3b and Bax in myocardial tissue of rats were detected 24 h after last medica-tion;ventricular index was calculated,and morphological change of myocardial tissue was observed. RESULTS:Compared with sham operation group,the plasma contents of Cr and ALD,ventricular index and the protein expression of LC3b in myocardial tis-sue increased significantly in model group (P<0.05 or P<0.01);and myocardial cell suffered from endochylema red deletion, myocardial cross striation disorder,intercellular space fibrosis aggravation and so on. Compared with model group,the plasma con-tents of Cr and ALD(except for positive control group)and the protein expression of LC3b and Bax in myocardial tissue decreased significantly in positive control group and SFQX pills high-dose group(P<0.05 or P<0.01);myocardial pathological change was improved;the ventricular index decreased significantly in SFQX pills low-dose and medium-dose groups (P<0.05). CONCLU-SIONS:SFQX pills can decrease the plasma contents of Cr and ALD,inhibit myocardial cell autophagy and apoptosis in CRS rats.

Hair follicle (HF), one of the skin appendages, has received a lot of attention to be a new target and pathway for drug delivery. The development of hair follicle targeted drug delivery system (HFTDDS) through percutaneous permeation is particularly important for skin diseases derived from HF such as acne, hair loss, and folliculitis for their on-site action. This review describes the structure and physiological function of HF, the microenvironment of HF, and factors affecting HF permeation. Multiple nanoformulations used to improve the HF permeation and technologies to characterize the HF permeation were introduced. The latest advance of HFTDDS based on nanoformulations were systematically summarized and analyzed in the treatment of acne and hair loss. Finally, the challenges of formulating HFTDDS were discussed. The review is expected to provide some ideas and references for developing delivery systems for treating skin diseases derived from HF.

With dwindling number of new antibiotics and inappropriate use of antibiotics, the emergence and spread of antibiotics resistance occurs commonly in healthcare institutions worldwide. In China, antibiotics are commonly overprescribed and misused. This study is to assess the effect of the nationwide special campaign on antibiotic stewardship program (ASP) at specialized hospitals in China by investigating prescription information from 2011 to 2012. Data on the hospital consumption and prescription of systemic antibiotics were obtained from four specialized hospitals, including maternity, children's, stomatological and cancer hospitals. Systematic random sampling was used to select outpatient prescriptions and inpatient cases. A total of 105 specialized hospitals in 2011 and 121 specialized hospitals in 2012 were analysed. The defined daily doses (DDDs) per 100 inpatient days, the percentage of antibiotic use in outpatient prescriptions, and the percentage of antibiotic use in inpatient cases were used as measurements of antibiotic use. The overall antibiotic use density in the selected hospitals decreased between 2011 and 2012 from 39.37 to 26.54 DDD/100 inpatient days (P<0.001). The percentage of antibiotic use in outpatient prescriptions (range: 24.12%-18.71%, P=0.109) and inpatient cases (64.85%-60.10%, P=0.006) also decreased within the two years. Significant changes were observed among regions and different hospitals within the two years. And antibiotic consumption was correlated with the type and size of specialized hospital in 2012, but not with the regions. This analysis of antibiotic consumption of specialized hospitals allows relevant comparisons for benchmarking and shows that national ASP has improved antibiotic rational use in China. The data will assist policymakers in formulating effective strategies to decrease antibiotic overuse and identify areas that require further work.
