Medical purpose is a concept of viewing the situation as a whole, development and perpetuity. It is important that how to realize the medical purpose but not define itself.There are similar main conten of medical purpose extending directly from various stages and existing between eastern and western countries, and this is determined by characteristics of mde-icine. However, the fommer concept of medical purpose will show relative partial deficiency, and its intension will enlarge in the new stage of social, ecconomic and medical development. It also brings us new methods, ideas of thought, and make them fit for the requirement of society to medicine and the non-fungible function of medicine to human health. So the central content of medical purpose is running after the health of person and human based on elevating life quality, maintain and enhance social productive forces. This is extreme purpose of medicine and common adimission of world medicine.The realization of medical purpose is guided and restricted by the concept of humanistic ethics. So, understanding and discussion of medical bepose must be carried out guided by it and its theory frame. The centre of mordern medical humanism is the respection to the human valuation related to medicine, including that of person, group and society. Primarily, the valuation is emphasized on the human life quality and health valuvation, which are directly and first reflected not only in mordern medical humanism, but also in medical purpose.In this sense, the intension of medical humanism is equivalent to the central content of medical prupose defined above all, and the medical humanism is medical purpose. The focus reflection of medical purpose is the thought of medical humanism, one is objective of medical developmant another is the thought and principle defined for achieving the objective.

Results:The linear range of chloramphenicol was 25. 6-512. 0 μg ·ml-1(r=0. 999 9). The mean recovery was 99. 4%, and RSD was 0. 8%(n=9). Conclusion:The method is simple,accurate and reproducible,and can be used in the determination of chloramphenicol vaginal tablets.

This article reports the development of hyperosmolar hypernatremic hyperchloremic coma and acute renal failure in a male diabetic patient after recovery from hyperosmolar hypergly-cemic nonketonic coma, of which the cause is fluid retention in excess of urinary output due to the obstruction of lower urethra by diabetic neurogenic urinary bladder and hyper-plasia of prostate gland.By our experience each old diabetic man should be examined to confirm if he has neuro-genic urinary bladder and/or hyperplasia of prostate gland. Care should be taken to keep the balance of fluid intake and output provided that both of these conditions are present. The acute obstructive nephropathy can quickly ameliorate with release of the obstruction.

Objectives:To assess the nutritional status of retired residents in a community by mininutritional assessment(MNA) combined with anthropometry. Methods:MNA questionnaire and anthropometric parameters including waistline,hipline,height,weight,body mass index(BMI),midarm circumference,triceps skinfold(TSF) and midarm muscle circumference were performed in 115 retired residents. Results:①24 (20.9%) residents had MNA scores less than 23.5,which meaned malnutrition or at risk of malnutrition.②According to each single index,namely waistline, waist hip ratio and BMI,incidence of obesity was 53.9%,61.7% and 65.2% respectively.③According to each single index,that is,midarm circumference,TSF and midarm muscle circumference,prevalence of moderate or severe malnutrition was 1.7%,19.1% and 2.2%respectively.④There lied a significant correlation between MNA score and several anthropometric parameters. Conclusions:①Both overnutrition and undernutrition can be manifested in retired home residents,for whom nutritional intervene should be enhanced.②MNA questionnaire can be well used in Chinese.

Objectives:To investigate the nutritional status of the maintenance hemodialysis(MHD) patients. Methods:The dietary investigation, anthropometry and biochemical tests were conducted in 46 MHD patients,including weight,triceps skinfold(TSF), arm muscle circumference(AMC), serum total protein(TP), albumin(Alb), prealbumin(PA), transferrin(TF) and ideal weight rate(IBW%).Then nutritional status was evaluated. Results:①The energy intake of most MHD patients was lower than 125.4 kJ/(kg?d) and the mean protein intake was nearly 1.0 g/(kg?d).②According to each single index,the incidence of malnutrition was:39.13% by IBW%, 71.74% by TSF, 58.70% by AMC, 30.43 % by Alb and 82.61% by TF respectively.Only 6.52% patients had all normal paremeters. Conclusions:Malnutrition incidence of MHD patients was as high as 93.48% in our study. The regular nutritional assessment and the nutritional advice are very important for the better clinical outcome in the MHD patients.

To explore the effects of nutritional risks on clinical outcomes [length of stay (LOS),hospitalization expense & mortality] in chronic kidney disease (CKD) patients.A total of 127 CKD patients completed the screening of nutritional risks by Nutritional Risk Screening 2002 (NRS-2002) within 24-48 hours of admission.The data of nutritional supports within 2 weeks of admission,LOS,hospitalization expense and mortality were collected.① Among them,the prevalence of nutritional risks was 18.1％.And the values were 8.2％,9.4％ and 44.1％ in early,middle and advanced CKD groups respectively; ② LOS and hospitalization expense in nutritional risk group were significantly more than the non-nutritional risk group (12.5 d vs.5.2 d,P =0.00 ; 11 806 vs.5311 yuan,P =0.00).There was a positive correlation between NRS score and LOS or hospitalization expense; ③ The nutritional support rate of nutritional risk group was only 17.4％.The progression of CKD increased the nutritional risks leading to greater LOS and hospitalization expense.We should pay more attention to the nutritional risk screening and nutritional intervention in moderate-advanced CKD patients.

Objective To screen differentially expressed microRNAs at different stages of hair cycle in a murine model.Methods This study included 30 inbred female C57BL/6 mice (age,6-8 weeks; body weight,15-18 grams).Hair growth cycle was induced in the back skin of C57BL/6 mice by application of wax/rosin followed by depilation under anesthesia witl 1％ chloral hydrate.Three mice were sacrificed by cervical dislocation on day 0,8 and 20 after the induction,and skin tissue was achieved from the same depilated areas parallel to the spine.Total RNAs were extracted from the murine skin and subjected to microarray analysis of microRNA expression.Results Compared with telogen skin,the murine anagen skin showed a higher expression of miR-690,obselote-49 and miR-1308,but a lower expression of miR-291a-5p and miR-212.The expressions of miR-690,obselote-49 and miR-31 were significantly up-regulated,while those of miR-127-3p and miR-212 were downregulated in the catagen skin in comparison with the telogen skin.Conclusion Seven microRNAs are identified in this study to be differentially expressed in murine skin between different stages of hair cycle,which may provide a direction for future research.

Objective To discuss the technique of Neuroform stent-assisted coil embolization for the treatment of intracranial wide-necked aneurysms and to evaluate its clinical efficacy and complications.Methods Neuroform stent-assisted technique was used for coil embolization treatment in 31 patients with intracranial wide-necked aneurysms, all aneurysms were ruptured and the patients suffered from subarachnoid hemorrhage (SAH). Of the total 43 aneurysms, 39 were wide-necked and 4 were narrow-necked. Results Thirty-five stents were inserted in 31 patients. The stents were implanted in both internal carotid arteries in 3 patients and in both middle cerebral arteries in one patient, Intra-arterial embolization with coils was successfully performed in 41 of 43 aneurysms. Intraoperative hemorrhage occurred in 2 patients, which probably resulted from the rupture of middle cerebral artery branch due to microwire damage. The cerebral isehemic symptom happened in 1 patient with posterior communicating artery aneurysm due to the shifting of the coil from the original site to M2 segment of middle cerebral artery. During a follow-up period of 24.7 months in average, neither death nor recurrent hemorrhage occurred in 29 cases. Twenty-eight patients were in good living condition and the remaining one patient showed obvious disturbance of neural function.Conclusion For the treatment of intracranial wide-necked aneurysms, intra-arterial coil embolization with Neuroform stent-assisted technique is a safe and effective clinical therapy. It can effectively broaden the extent of indications in treating intracranial aneurysms by using interventional technique.

Objective To investigate bone strength in adults,and explore its influencing factors. Methods One hundred and ninety-one adults undergoing health examinations were selected.The questionnaires about milk intake and exercise conditions were performed,the body weight,fat mass,body mass index(BMI)and calcaneal bone strength were measured,and the relationship between each parameter and bone strength was analysed. Results Bone suength decreased with age increase,and was higher in males than that in females.Bone strength of overweight to obese adults was higher than that with normal body weight(P<0.05).Bone strength of adults with high milk intake was higher than that of those with low milk intake(P<0.05).Multivariate analysis revealed that age was negatively related to bone strength,females were more susceptible to bone strength decrease,and BMI and milk intake were positively related to bone strength. Conclusion Gender,age,BMI and milk intake are main influencing factors for bone strength.Bone strength decreases with age increase,and increase of BMI and milk intake will benefit bone strength,especially for females.
