Objective: 1)To revise the Social Skills Scale (SSS) and examine its psychometric properties.2) To explore the relationship between SSS and mental health. Methods:1)A sample of 394 freshmen completed the Social Skills Scale, SCL-90, and Self Consistency and Congruence Scale. Exploratory factor analysis, item analysis, reliability and validity analysis were used to revise the Social Skills Scale. 2) The relations between the SSS , SCL-90 and Self Consistency and Congruence Scale were examined.Results:Using exploring factor analysis, 5 factors were extracted, i.e. social adaptation, social perception, social confidence, social expression, and impression management. The mean inter-item correlation coefficients ranged from 0.52 to 0.77. The correlation coefficients of item and corresponding subscale ranged from 0.52 to 0.77, and the item discrimination indexes ranged from 0.32 to 0.52. Social adaptation, social perception and impression management were positively correlated with mental health. Social confidence was negatively correlated with mental health. Social expression did not correlation with mental health. Conclusion:The revised Social Skills scale was an reliable and valid measurement.

To study the effect of hyperbaric oxygen (HBO) on cellular proliferative nuclear antigen (PCNA) in spinal cord after its injury (SCI), we observed the pathological changes and the expression change in PCNA in spinal cord after the injured rats were treated with HBO. The results showed that there were hemorrhage, edema, vacuolation of nerve cells in spinal cord, disorder and fragmentation in nerve fibers after injury. PCNA was strongly positively expressed in neurons. The results in 0.1MPa HBO group were similar to that of non-treatment group, while in 0.25MPa HBO group, edema was abolished, the cellular vacuolation was lessened, the morphology of nerve cells recovered, the structural configuration appeared normal, and the degree of PCNA expression was decreased compared with the injury group. These results suggested that PCNA could serve as a cellular proliferative index; HBO could prevent or alleviate the pathological changes of SCI, and could effectively promote the repair of the injury of the spinal cord.

Objective To understand and raise the level of osteopomsis-relied knowledge, attitudes and behaviors for prevention and treatment of osteoperosis(OP)in residents of a community. Methods A survey was performed with a questionnaires method targeting at the elderly residents in Changfeng community.The survey was conducted with a specifically designed questionnaire,followed by a second survey.during which health edueafion was stressed.Data were analyzed with SPSS 11.0 software. Results In 3524 residents.3367 responded positively.The ratio of male to female was 1:2.10.The average age of the respondents was 61.34 years.They demonstrated a low level of OP KAP.76.72% of them heard the term of OP,60.11% had a correct judgment of their own bone heahh,42.26% knew the cause of OP.and 37.75% understood the diagnostic method of OP.The level of OP KAP varied in different groups of targeted residents.Of all the questions.the understanding of the diagnosis ranked the lowest.2281 people participated in the second survey,which showed improvement in their OP KAP.The difference was statistically significant.1439 people auended the consultation.99.86% of them considered the activities necessary,96.92% expressed their satisfaction,and 98.54% planed tO take measures to improve their bone health.Conclusion The poor understanding of bone heaith status and the knowledge about prevention and treatment of OP is why it is widely spread in the modem society,which however Call be improved by education.

Objective To observe the effect of electroacupuncture and nerve and tendon gliding exercises on mild to moderate carpal tunnel syndrome.Methods Forty patients with mild to moderate carpal tunnel syndrome were randomly divided into an observation group and a control group,each of 20.Both groups were given neurotrophic drugs.The observation group was additionally provided with electroacupuncture and nerve and tendon gliding exercises,while the control group was given routine health education for 4 weeks.The Boston carpal tunnel syndrome questionnaire (BCTQ),a visual analogue scale (VAS),thumb and middle finger to wrist motor conduction velocity (MCV),sensory nerve action potentials (SNAPs),median nerve distal motor latency (DML) and the amplitude of compound muscle action potential (CMAP) of the musculi abductor pollicis brevis were evaluated.Results There were no significant differences in any of the measurements between the two groups before the treatment.After four weeks of treatment,significantly better improvement was observed in the average SCV of the thumb and wrist,the SCV of the digitus medius and wrist,the SNAP of the thumb and wrist,the SNAP of the digitus medius and wrist,the DML of the nervus medianus and the CMAP of the abductor pollicis brevis in the observation group compared to before the treatment and compared to the control group.Moreover,there was a significant decrease in the observation group's average BCTQ symptom score and function score and in their VAS ratings.However,in the control group significant differences were only found in the average SCV of the thumb and wrist,the DML of the nervus medianus and in their VAS ratings.Conclusions Electroacupuncture and nerve and tendon gliding exercises can significantly relieve symptoms and restore hand function.They are worth applying in clinical practice.

Objective To determine the expression of Notch pathway receptors (Notch1 and Notch4) and ligands (Jagged1 and Dll4) in cutaneous malignant melanoma (CMM) tissues,and to preliminarily explore the role of the Notch signaling pathway in the pathogenesis of CMM.Methods Immunohistochemical study was performed to determine the expression pattern and intensity of Notch1,Notch4,Jagged1 and Dll4 in 40 paraffin-embedded CMM specimens and 15 paraffin-embedded pigmented nevus specimens.Statistical analysis was carried out by chi-square test and Spearman rank correlation analysis with the SPSS 21.0 software.Results Notchl was detected in 31 (77.5％) of 40 CMM specimens,as well as in 3 of 15 pigmented nevus specimens,and the positive rates significantly differed between the two groups (x2 =15.281,P ＜ 0.001).However,no significant difference in the expression intensity of Notch1 was observed between 18 in situ melanoma tissues and 22 invasive melanoma tissues (x2 =0.631,P =0.427).In addition,the positive rates of Notch4,Jagged1 and Dll4 were also significantly higher in the CMM group than those in the pigmented nevus group (all P ＜ 0.05),and the expression intensity of Notch4,Jagged1 and Dll4 significantly differed between in situ and invasive melanoma tissues (all P ＜ 0.05).In CMM tissues,the expression of Notch1 was positively correlated with that of Jagged1 (rs =0.350,P =0.027) and Dll4 (rs =0.562,P ＜ 0.001),while the expression of Jaggedl was negatively correlated with that of Dl14 (rs =-0.734,P ＜ 0.001).Conclusion Abnormality of the Notch signaling pathway may be involved in the pathogenesis of melanoma,but further researches are still needed to elucidate the detailed mechanism.

Objective To investigate the effects of exercise therapy and health education on the hospitalization and exercise endurance of patients with moderate or severe chronic obstructive pulmonary disease (COPD).Methods A total of 86 patients with moderate or severe but stable COPD were divided randomly into an observation group (n=46) and a control group (n=40).The patients in both groups accepted general respiratory medical therapy.The patients in the observation group also accepted additional pulmonary rehabilitation therapy which consisted of exercise and health education while the patients in the control group only accepted health education and rehabilitation training guidance by telephone instead of standardized pulmonary rehabilitation therapy.The average recurrence of hospitalization,length of stay,and total bed time of all of the patients was tracked for a year before and after enrolment.Their 6 minute walking distance (6MWD) and quality of life (QOL) as reflected by using a scale recommended by the Chinese Society of Respiratory Disease before and after entering the study were evaluated.Results There was no significant difference between the groups in the year before entering the study in terms of their average frequency of hospitalization,length of stay or total bed time.In the year after enrollment average frequency of recurrence requiring hospitalization,length of stay and total bed time in the observation group all decreased significantly compared with the previous year,and all were significantly lower than in the control group.There were no significant differences between the groups in average 6MWD or average QOL score at entry,but in the subsequent year both groups' results improved significantly.Conclusion Long term pulmonary rehabilitation can not only enhance exercise endurance,it also improves QOL and relieves the economic burden of COPD patients on society.

The clinical course of mycosis fungoides is indolent except when large cell transformation occurs. Large cell transformation of MF is rare and easy to misdiagnose. A case of large cell transformation of mycosis fungoides is reported. A 40-year-old man presented with a 10-year history of pruritic erythema and papules in the trunk and extremities as well as a 5-month history of nodules on the nape of the neck.Histopathologically, the erythematous patch showed typical changes of mycosis fungoides, while the tumor cells were small and expressed CD3 and CD4, and only a small number of tumor cells expressed CD30. Pathological examination of nodular lesions revealed the infiltration of large pleomorphic lymphoid cells expressing CD3 and CD4 throughout the entire dermis. There was an epidermotropism of large cells, and about 40% of these cells expressed CD30. Based on the medical history and histological findings, the patient was diagnosed with large cell transformation of mycosis fungoides. The lesions improved markedly after 3-week treatment with oral acitretin (30 mg once daily), subcutaneous interferon-alpha (2 × 106 IU thrice a week) and local superficial X-ray irradiation for nodular lesions. Up to the time of this writing, the patient had been followed.

BACKGROUND: Studies have confirmed that RhoA/ROCK signaling pathway plays an important role in the process of epithelial-mesenchymal transition. OBJECTIVE: To investigate the effect of Y-27632 (inhibition of rhodopsin kinase of 4-aminopyridines compounds) on the epithelial-mesenchymal transition of rat peritoneal mesothelial cells (RPMCs) induced by transforming growth factor ?1 (TGF-?1). DESIGN,TIME AND SETTING: An animal observational experiment was performed at the Laboratory of Nephrology in the First Affiliated Hospital of Sun Yat-sen University from March 2007 to March 2008. MATERIALS: A total of ten healthy male Sprague Dawley rats were provided by the Animal Experimental Center of Sun Yat-sen University. Y-27632 was the product of Calbiochem Company (German). TGF-?1 was the product of R&D Company (USA). METHODS: Primary RPMCs were cultured in vitro. After synchronization for 24 hours, RPMCs were randomly divided into 4 groups: control group (RPMCs cultured in the DMEM/F12 without serum), TGF-?1 group (RPMCs cultured in the DMEM/F12 without serum, and then added 10 ?g/L TGF-?1), Y-27632 group (RPMCs cultured in the DMEM/F12 without serum, and then added 10 ?g/L Y-27632), TGF-?1 +Y-27632 group (RPMCs cultured in the DMEM/F12 without serum, and then added 10 ?g/L Y-27632. 2 hours later, 10 ?g/L TGF-?1 were added). The cells were collected 48 hours after culture. MAIN OUTCOME MEASURES: The mRNA and protein expression of E-cadherin and ?-Smooth muscle actin (?-SMA) were measured by RT-PCR. The protein expression level of E-cadherin, ?-SMA and vimentin was measured by Western blotting. RESULTS: Compared to control group, the expression of E-cadherin significantly decreased in the TGF-?1 group, and the expression of ?-SMA and vimentin significantly increased (P

Objective To compare the sensitivity of four kinds of drug susceptibility test method in detecting sensitivity of tigecycline against Acinetobacter baumannii.Methods The susceptibility of 72 clinically isolated strains of carbapenemase-resistant Acinetobacter baumannii(CRAB) to tigecycline in vitro was detected with disk diffusion method,VITEK 2 Compact system,E-test and MIC test strip(MTS) test strip respectively,according to FDA standards,and the differences of four kinds of drug susceptibility test methods were compared.Results The susceptibility rates of 72 strains of CRAB to tigecycline by disk diffusion method,VITEK 2 Compact system,E-test and MIC test strip were 50.00%,69.44%,36.11% and 98.61% respectively,the intermediate rates were 48.61%,29.17%,26.39% and 1.39% respectively,the resistant rates were 1.39%,1.39%,37.50% and 0.00% respectively.Compared with MTS,the classification consistency rates of E-test,disk diffusion method and VITEK 2 Compact system were 36.11%,51.39% and 70.83% respectively.Conclusion There is difference among four kinds of method for conducting the drug susceptibility testing of tigecycline against CRAB,the consistency of disk diffusion method,VITEK 2 Compact system and E-test is lower.Detecting mediation or drug resistant strains of CRAB by disk diffusion method,VITEK 2 Compact system and E-test needs to be verified by MTS or Broth dilution method.

Objective:To explore the relationships between perfectionism and coping strategies among graduate students.Methods:396 college graduate students completed the COPE (the Coping Inventory),FMPS (Frost's Multidimentional Perfectionism Scale) and General Self-efficacy Scale.Results:①Significant positive correlations were found between adaptive perfectionism and self-efficacy,while negative correlations between doubt about actions in maladaptive perfectionism and self-efficacy;② Regression analysis indicated predictability of perfectionism and self efficacy to coping strategies.Self-efficacy still had significant predictability after perfectionism and its sub-dimension were controlled.Conclusion:Self-efficacy plays an important mediation role between perfectionism and coping strategy.
