OBJECTIVE: To analyze the effects of social and psychological factors on rehabilitation status of end stage renal disease (ESRD) patients under peritoneal dialysis. METHODS: From August in 2005 to March in 2007, 171 patients experienced peritoneal dialysis were diagnosed at the Center of Peritoneal Dialysis, Department of Nephrology, First Hospital, Peking University, including 66 males and 105 females, aged (60±13) years, with an average dialysis time of 22.8 months. They were studied with questionnaires and interview. Rehabilitation status was investigated from two aspects of activity and participation by Karnofsky activity index, Social Dysfunction Screening Scale. Hamilton depression and anxiety scales, Medical Coping Modes Questionnaire and Social Supporting Rating Scale were used to investigate social and psychological factors.RESULTS: A total of 200 questionnaires were handed out and 171 (85.5%) of them were drawn in. 134 patient had normal activity status, 78.4% of them had Dysfunction and 129 patients (75.4%) had normal social function status. Forty-two (24.5%) of patients had the symptom of anxiety, 15 (8.2%) had depression. The score of "Acceptance-Resignation" was significantly higher in this group than patients with other chronic diseases. There were no significant differences in scores of "Confrontation" and "Avoidance". Activity of rehabilitation outcome and participation index served as dependent variable, whereas depression and anxiety, coping mode and social supporting as independent variable. Using multiple stepwise regression analysis, factors that affected patient rehabilitation were found, including depression, utilization of social support and the facing coping mode. CONCLUSION: Depression, utilization of social support and the facing coping mode have important effects on patient rehabilitation.

Objective To test the reliability and validity of ICF Core Sets for Chinese COPD patients.Methods Fifty-two COPD patients were measured with ICF Core Sets for COPD patients and SF-36. For reliability test, the internal consistency was analyzed and expressed by Cronbach α coefficients and split-half reliability. For va-lidity test, the content validity and criterion validity were analyzed and expressed with Spearman rank correlation coef-ficients. Results For body function, body structure and activity and participation, there were good internal consis-tency (Cronbach α coefficients 0. 698～0.957). For environmental factors Crnnbach α coefficient and split-half reli-ability did not exist. Most items of body function, activity and participation and body structure possessed good content validity. There was concurrent validity for ICF components of body function, body structure and activity and participa-tion with SF-36, FEV1/FVC, COPD grade and health self-assessment. The environmental factors demonstrated poor reliability and validity. Conclusion The ICF Core Sets for COPD patients showed good reliability and validity. It is a good comprehensive functional measurement scale for COPD patients, but it is necessary to test the generality of this result, and some items need to be adjusted.

Objective To evaluate the efficacy of Qingfei-Jiedu decoction in the treatment of Acne. Methods A total of 93 female patients with acne were randomly divided into 3 groups according to random number table, 31 in each group. The observation group took the oral Qingfei-Jiedu decoction, and the Chinese medicine control group took the oral tanshinone capsule, and the western medicine control group took the oral acetic acid ring propyl alcohol progesterone. All 3 groups were treated for 4 weeks. The levels of serum dihydro (DHT), IL-6 and IL-8 were measured by ELISA. The changes of the lesions before and after treatment were observed and the adverse events were recorded during the treatment. The clinical effect was evaluated. Results After treatment, the serum DHT (56.94 ± 15.74 pg/ml vs. 74.48 ± 18.53 pg/ml, t=2.089), IL-6 (22.84 ± 11.77 pg/ml vs. 30.37 ± 14.50 pg/ml, t=2.135), IL-8 (22.64 ± 7.38 pg/ml vs. 29.54 ± 9.65 pg/ml, t=2.057) in the observation group were significantly lower than those in the Chinese medicine control group (P<0.05). After treatment, the disappearance rate of skin lesions (65.4% ± 15.0% vs. 44.7% ± 12.9%, 42.7% ± 13.6%, F=6.862) and comprehensive syndrome effective rate (57.2% ± 12.6% vs. 46.3% ± 12.8%, 44.8% ± 11.7%, F=5.322) in the observation group were significantly higher than those in the other two control groups (P<0.05). The observation group and the traditional Chinese medicine control group did not have adverse events, but the western medicine control group showed one case nausea. Conclusions The Qingfei-Jiedu decoction can reduce the level of serum DHT, IL-6 and IL-8 in female patients with acne vulgaris, and improve the skin lesion disappearance rates and comprehensive syndrome rates.

Objective To investigate the electrophysiological changes of peripheral nerves in both patients with hereditary neuropathy with liability to pressure palsies(HNPP).Methods The nerve conduction velocities of a family consisting of a proband and 4 members were tested,and the proband was detected by biopsy.Results The proband's median nerve,ulnar nerve,sural sensory nerve conduction velocity (SCV) were decreased.The median nerve,ulnar nerve,common peroneal nerve motor nerve conduction velocity(MCV) of proband were decreased.The sensory fibers of the most frequently involved nerve sural nerve,sural nerve damage to the results:the motor nerve conduction motor nerve evoked potential latency and 18 abnormal rate was 75.0％,the nerve distal to the abnormal rate of MCV was 87.5％.Conclusion Prolongation of distal nerve conduction latencies occurs in essentially all individuals whether symptomatic or asymptomatic.Nerves may be more easily damaged at the site of compression.

Objective To evaluate the diagnostic value of bedside lung ultrasound on severe pneumonia in elderly patients.Methods Bedside lung ultrasound lung ultrasound and chest CT were performed in 104 elderly patients admitted to the emergency department for suspected severe pneumonia,from November 2010 to January 2013.According to the characteristics of the chest CT image,patients were divided into consolidation group (big leaf or lung segment distribution density shadow) and the unconsolidation group (for the performance of the cable sample,ground glass sample,or small patch sample changes).Differences in ultrasonic characteristics were compared between the two groups.Results Ultrasonic image characteristics were pulmonary consolidation,subpleural lesion,pleural changes and parapneumonic effusions in patients with severe pneumonia.Among 65 patients with chest CT image of pulmonary consolidation in consolidation group,60 patients were found pulmonary consolidation by lung ultrasound,and all 39 patients in unconsolidation group were not found pulmonary consolidation by lung ultrasound,and there was a significant difference in detect rate by lung ultrasound between the two groups (x2 =87.546,P＜ 0.001).The number of subpleural lesion and pleural changes were (1.16 ± 1.07) and (3.14 ± 2.20) respectively in consolidation group and (3.85 ± 1.93) and (11.73 ± 3.69) respectively in unconsolidation group,which had significant differences between the two groups (t=7.439,12.133,both P＜0.001).There was no significant difference in the incidence of parapneumonic effusions between the two groups (45/65 vs.29/39,x2 =0.086,P=0.496).Conclusions Ultrasound image characteristics of severe pneumonia in elderly patients included pulmonary consolidation,pleural lesions,pleural changes and parapneumonic effusions.Ultrasonic characteristics will be pleural lesions,pleural changes in severe pneumonia patients without chest CT image of pulmonary consolidation.
