The CHISS statistical software which has its own copyright protection in China is applied to the teaching in medical statistical. A questionnaire was carried out among 135 applicants after they had learnt the modern statistical method for 18 teaching hours and practiced on computers with CHISS for 6 teaching hours. Those applicants gave out the evaluations: CHISS has the character of convenient and visual demonstration. It can meet the needs of medical statistical teaching and doing research.

There exist a series of problems in heat stroke treatment,such as,pathogenesis is still unclear,clinical classification is too simple and has no intrinsic relation with pathophysiological process and prognosis,missing of indexes for hierarchical diagnosis and prognosis prediction,and lack of targeted therapeutic norms.All of these factors could lead to high mortality and disability by heat stroke.Our research team started an epidemiological investigation of heat stroke since 2002.On the basis of discovering organ injury rule,system info and treatment technology on critical medicine were applied to heat stroke treatment.Research on organ injury mechanism for heatstroke was carried out based on translational medicine idea,and periodic research results were also achieved.A series of key technologies for heat stroke treatment were obtained.These technologies were popularized in 30 hospitals across the country,thus improving ability of heat stroke treatment.

It is an important topic in life science research to study the method of intervening sub-health. Previous studies indicated that traditional Chinese medicine (TCM) has unique advantages in sub-health intervention. In this paper, TCM sub-health intervention was summarized from such aspects as diagnosing according to syndrome differentiation, application of herbal medicine and Chinese patent medicine, herbal cuisine and medicated bath. At the same time, the paper discussed methods of sub-health comprehensive intervention, the relation between individual physical factors and sub-health, and the potential influence of the sub-health intervention on the innovation of Chinese medicine health insurance.

Non-Drug Therapy has good advantages for sub-health state.Commonly used methods of non-drug therapy are health education,life conditioning,physical exercise,psychological adjustment,acupuncture,massage and etc.TCM has obvious advantages in the field of non-drug therapy,showing broad prospects.

BACKGROUND: Differentiation of neural stem calls (NSCs) was mediated by many environmental factors. Several factors can induce NSCs to differentiate into neurons in varying degrees and it is now a focus on the control of NSCs differentiation.OBJECTIVE: To study the effects of combination of basic fibroblast growth factor (bFGF) and brain-derived neurotrophic growth factor (BDNF) on the differentiation of NSCs into neurons.DESIGN, TIME AND SETTING: The in vitro cytology observation was performed at the Neurotomia Laboratory of China Medical University in May 2008.MATERIALS: Three adult male SD rats were provided by Experimental Animal Center of China Medical University.METHODS: Dispositions to the rats were consistent with ethical standards of animals. The rat brain hippocampus was removed sterilely. After trypsin digestion, NSCs were cultured in serum-free medium. Cell suspension was prepared and diluted when the diameter of the fourth passage of clone sphere was 200 μm by mixture of DMEM/F12 containing 2% B27, 20 μg/L of epidermal growth factor (EGF), and 20 μg/L bFGF. Monoclonal calls were passagad. NSCs were divided into blank control, bFGF, BDNF and bFGF+BDNF groups by different growth factors added into the media. Fetal bovine serum of 0.1 volume fraction was added in blank control group. The media in the other three groups were added bFGF, BDNF and bFGF+BDNF respectively for 1 week.The concentration of bFGF was 10 μg/L and the concentration of BDNF was 200 μg/L.MAIN OUTCOME MEASURES: Immunocytochemistry staining was used to identify NSCs as well as to detect the differentiation of NSCs into neurons.RESULTS: The monoclonal calls expressed nestin and the differentiated call expressed neuron specific enolase and glial fibrillary acidic protein. Compared to blank control group, the proportion NSCs into neurons in the bFGF group, BDNF group and bFGF+BDNF group were much higher (t=3.409-7.558, P < 0.05), with the highest in bFGF+BDNF group (t =7.558, P < 0.05).CONCLUSION: Combination of bFGF and BDNF can promote the differentiation of adult hippocampus NSCs into neurons.

Objective To investigate the effect and safety of thoracic drainage by central venous catheter in critical patients with pleural effusion. Methods A prospective study was carried out,in which 46 critical patients with pleural effusion admitted to department of critical care medicine were included,and according to the types of their primary diseases to make matched pairs,and they were divided into two groups:conventional drainage control group and central venous catheter drainage observation group(each 23 cases). The drainage effect and complications were compared between the two groups,acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)score, quantitative pleural effusion and the counts of white blood cells(WBC)and of platelets(PLT),the levels of prothrombin time(PT),procalcitonin(PCT)and C-reactive protein(CRP),etc. were measured on the baseline and 24 hours after the operation. Results There were no significant differences in the APACHEⅡ score,quantitative pleural effusion,amount and duration of drainage,as well as the levels of WBC,PLT,PT and PCT between group control and observation(all P>0.05). The post-drainage CRP(μg/L)level in group observation was much lower than that in group control(77.26±67.20 vs. 106.13±66.23,P<0.01). There was a trend that the incidence of complication in group control was higher than that in group observation(26.1%vs. 4.3%),but the difference was not statistically significant(P>0.05). Conclusions In the comparison between the conventional drainage and thoracic drainage with central venous catheter,the therapeutic effects for treatment of critical patients with pleural effusion were similar, but the stress was milder and the incidence of complications was lower in the latter group. Therefore,the thoracic drainage with central venous catheter is a safe,effective and alternative method to substitute the conventional drainage for critical patients with pleural effusion.

Objective To examine the difference in the onset of and recovery from the neuro-muscular (N-M) blockade induced by rocuronium measured by acceleromyography of corrugator supercilli (CS) muscle and adductor pollicis (AP) muscle and the implication for clinical N-M monitoring. Methods Forty ASA Ⅰ - Ⅲ patients aged 32-65yr undergoing elective cholecystectomy or gastrectomy under combined general-epidural anesthesia (CGEA) were randomized to receive rocuronium 0.6 mg?kg-1 (group A, n = 20) or 0.9 mg?kg-1 (group B, n = 20) to facilitate tracheal intubation. Patients with N-M transmission disease, serious heart and lung disease or hepato-renal dysfunction were excluded. Epidural was performed at T8-9 or T9-10 . The level of epidural block was below T4. N-M blockade was measured by acceleromyography (TOF-WATCH SX Organon Teknika) of AP muscle at the thumb and CS muscle at the superciliary arch simultaneously. General anesthesia was induced with midazolam 0.05 mg ? kg-1 , propofol 2 mg ? kg-1 , fentanyl 3 ?g ? kg-1 and rocuronium 0.6 or 0.9 mg ? kg-1 . Tracheal intubation was performed at 80 % depression of T1 . The intubation condition (rated as excellent, good, medium, poor). The onset time (time from injection of rocuronium to maximal depression of T1) and the time of return to 25% and 75% of the control height of T1 were recorded and recovery index (RI) was calculated. Results The onset time of N-M block of CS muscle was (111?36)s at 0.6 mg?kg-1 and (74 ? 26)s at 0.9 mg?kg-1 and that of AP muscle was (106 ? 34) s (0.6 mg?kg-1 ) and (84?28) s (0.9 mg?kg-1 ) . The onset time produced by 0.9 mg?kg-1 was significantly shorter than that produced by 0.6 mg?kg-1 . At 0.6 mg?kg-1 80% depression of T1 of AP muscle was equal to 66% (52%-81 % ) depression of T1 of CS muscle and only 2 out of 10 patients showed good intubation condition. At 0.9 mg?kg-1 80% depression of T1 of AP muscle was epual to 89% (76%-93%) depression of T1 of CS muscle and all patients showed good intubation condition. The recovery of CS muscle from relaxation was faster than that of AP muscle. Conclusion There are differences in the onset of and recovery from the N-M blockade induced by rocuronium between CS and AP muscle. Monitoring N-M blockade of CS muscle is better for intubation.
