Objective To summarize the clinical experiences in microsurgical treatment of severe children hand injuries caused by firecrackers. Methods 26 cases of children hand injuries caused by a firecracker blast were treated with microsurgical procedures. An emergency operation was done for 23 cases, and a delayed repair was done for 3 cases. Operative procedures differed from case to case, according to the injury type. Results All flaps and reconstructed thumbs survived completely by first intention. Of the 9 cases with 11 fingers replanted, 7cases with 9 fingers survived. The follow up for over two years showed that satisfactory restoration of hand function and shape was achieved and the replanted fingers also showed satisfactory restoration of holding and finger to palm and finger to finger functions. Conclusion Severe children hand injuries caused by a firecracker blast must be treated as soon as possible with microsurgical procedures. Preoperative planning of a proper repair or reconstruction approach is also of great importance.

Satellite cells, as the major stem cells, are responsible for postnatal skeletal muscle growth, regeneration and maintenance. As a result, satellite cells have great potential as therapeutic agents. Activation of satellite cells in vivo is a key link in the muscle regeneration processes. And their replenishment is necessary to keep the capacity of skeletal muscle to regenerate after recurrence of muscle damage. Cellular and molecular regulation of activation and replenishment for satellite cells issues were reviewed. Hoping through the points of nitric oxide-hepatocyte growth factor (NO-HGF), myostatin and Notch signaling and the niche of satellite cells to overcome the recent obstruction in cell therapy in clinic myopathy, such as Duchenne muscle destrophy.

Objectives To compare the value of different criteria (WHO, IDF and CDS criteria) on the diagnosis of metabolic syndrome (MS) in the elderly people. Methods 2 456 elderly patients admitted to General Hospital of PLA for routine physical examination during 1996 to 2005 were involved in present study. The value of different criteria (WHO, IDF and CDS criteria) on the diagnosis of metabolic syndrome (MS) was compared. Results The incidences of MS in the involved patients were 27.2%, 27.0% and 42.6%, respectively, according to WHO, IDF and CDS criteria. The diagnostic coincidence of CDS and IDF criteria was 79.0%. For the 1759 cases with the waistline data, the incidences of MS were 32.3%, 37.8% and 53.8%, respectively, according to the above three criteria. The diagnostic coincidence of CDS and IDF criteria was 76.5 %. According to the criteria of WHO, IDF and CDS, central obesity was detectable in a rate of 35.9%, 49.6% and 52.2%, respectively. Hypertension was diagnosed in a rate of 61.6%, 72.4% and 61.6%, and abnormal glucose metabolism was found in a rate of 24.9%, 40.5% and 24.9%, respectively. The most common clinical symptom complex of MS was hypertension, impaired glucose tolerance and abnormal lipid metabolism. Conclusions A higher coincidence exists between CDS and IDF criteria for MS, but the incidence of MS is higher in CDS criterion compared to WHO and IDF criteria. It is indicated that more attention should be paid on the measurement of the waistline in the elderly people. It seems more appropriate that the waistline data in CDS criterion should be modified from 85cm to 90cm for the elderly people, however, this should be verified by more epidemiological investigation.

This paper introduces a kind of design scheme with the application of M-bus to concentrated oxygen supply data acquisition and measurement.The method to integrate all kinds of consumable equipments and products of different companies is also presented.It is proved that the data acquisition system by M-bus can be applied to concentrated oxygen supply data acquisition and measurement in hospital.

To evaluate the prevalence and incidence of coronary heart disease (CHD) and associated risk factors with CHD in the elderly, a survey was conducted among old subjects aged 60 to 90 who had health examination in PLA General Hospital from 1996 to 1997. A cohort population without CHD had been followed up until 2000, and the incidence of CHD was calculated as the baseline. The incidence of CHD was calculated by person year method. The risk factors of incidence in CHD of different groups were analyzed with multiple logistic regression at the end of four observation years. The incidences of CHD and myocardial infarction (MI) of IGT and DM group were significantly higher than that of NGT group( P

ObjectiveTo establish nude mouse tumor models bearing human pancreatic adenocarcinoma SW1990 cells in multiple sites at different time-points and investigate the feasibiilty of multiple tumor-bearing in these models; then the findings and detection rate of 3.0T magnetic resonance image (MRI) in subcutaneous transplanted tumors was analyzed. Methods A total of 6 BALB/C nude mice were randomized into 3 groups (2 mice per group ).At the 1st,8th,15th day,the mice were injected subcutaneously with the suspension of SW1990 cells at left axilla and right axilla and right groin in sequence.Three weeks later,all the bearing-tumor mice were performed with MRI non-contrast enhanced scanning plus Gd-DTPA enhanced scan and the subcutaneous masses were subjected to pathological analysis.ResultsAll the 6 nude mice were alive during the study and obvious mass was observed in every injected site.The tumor size was positively associated with the grwing time.There were 9 tumors which could be de.ted by noncontrast enhanced MRI scanning and one more tumor was detected by contrast enhanced scanning.2 tumors were not detected,the 2 tumors were located at subcutaneous of right groin,with the shortest growing time,and the major axis of the 2 un-detected tumors was less than 5mm.Despite the MRI findings of the transplanted masses similar to that of human pancreatic adenocarcinoma with bleeding,necrosis,they presented the characteristics of a clear rim,with pseudocapeule sign.All the 12 masses were similar with human pancreatic adenocarcinoma under light microscope.ConclusionsIt is feasible to transplant human pancreatic adenocarcinoma cell at three different subcutaneous sites (injected at three different points of time) in the nude mouse,with a minimal survival time of three weeks.However,routine 3.0T MRI cannot detect the early tumors (growing time within 1 week,major axis ＜5 mm).

Objective To develop a set of health status questionnaire in line with health management demands for different physical examination reeeivers. Methods Based on literature review and clinical practice, sleep, pain, anxiety, depression, stress, fatigue, habits and social adaptation could be used as health items. An item database was set according to domestic or abroad established questionnaires. The items were screened to constitute our health status questionnaire. A total of 2866 individuals were randomly chosen to get the reliability or validity test. Results The correlation coefficient of single item with total score was 0.361-0.683. The Cronbach'α of sub-scales was ≥ 0.945, the retested reliability coefficient of was ≥ 0.677, and split-half reliability coefficient was ≥0.835. Eight factors in exploratory factor analysis explained 69.37% of total variance. Confirmatory factor analysis showed high degree of fitting. Conclusion Our health status questionnaire has higher reliability and validity and can be used for health data collection.

Objective: To investigate the hemodynamic changes of ophthalmic artery(OA) and central retinal artery(CRA) in patients with primary angle-closure glaucoma(PACG) and the effects of intraocular pressure(IOP) on retrobulbar hemodynamics. Methods: Following the measurement of IOP by non-contact tonometry,hemodynamic changes of OA and CRA were examined by color Doppler imaging(CDI) in 45 patients(90 eyes) with PACG,who were divided according to IOP into a hypertension(38 eyes) and a normal tension group(52 eyes).Observations were made of the peak systolic velocity(PSV),end-diastolic velocity(EDV),pulsatility index(PI) and resistance index(RI).Results: Significant differences were found between the PACG patients and the normal controls in CRA-EDV(P

The concept of the health promoting hospital, a modern mode of medical service that has turned from the formerly unitary pattern of medical treatment to the health promoting and life quality improving pattern of medical treatment, prevention and health care, was proposed by modern medical institutions so as to keep up with the change in medical modes and medical socialization. In recent years, many countries in the world have adopted the advanced service ideas of the health promoting hospital and conducted active research on various specific subjects. The paper gives an account of the concept, basic theories, development history, and latest progress both at home and abroad of the health promoting hospital so as to give an impetus to health education and health promotion in China.
