Objective: To explore health resource allocation and optimization and evaluate the clinical departments efficiency in hospital. Methods: Taking a three level of first-class hospital in Beijing for example, the method of data envelopment analysis (DEA) was used for building a DEA model of clinical departments efficiency in hospital. Results: Based on the results of the DEA model, we drawn the technical efficiency and scale efficiency of the target clinical departments, obtained input redundancy rates and output deficiency rates of the non-effective decision-making units. Conclusion:By DEA evaluation results, the input redundancy and output deficiency of the target clinical departments are found. From the perspective of optimizing hospital resource allocation, measures to improve the hospital operational performance are proposed. There is important significance to improve the comprehensive competitiveness of the hospital.

AIM: To investigate the immunoblot changeS of dystrophin expression in mdx mice after bone marrow stem cells transplantation. METHODS: The experiment was conducted in the laboratory of Department of Neurology, the First Affiliated Hospital, Sun Yat-sen University from September to December 2004. ①Twenty-five mdx mice of 7-8 weeks old were selected and randomly divided into transplantation 4, 8, 12 and 16 weeks groups and blank control group with 5 mice in each group. Meanwhile, 20 C57 mice of 4 to 6 weeks old were selected as donor mice, and 5 C57 mice aged 10 weeks served as positive control mice. ②All mice were preconditioned with 7 Gy ?-ray. After radiotherapy, 2?107 marrow stem cells per mouse (about 0.3-0.5 mL) were injected into the vena caudalis of mice; 0.3 mL PBS was injected into the blank control group and positive control group. ③The mice in 4 transplantation groups were killed at each time point, and the gastrocnemius was harvested to prepare dystrophin samples. The amount of dystrophin expression was detected by Western blot with GAPDH as control. RESULTS: All 25 mdx mice and 5 C57 mice were involved in the result analysis. Western Blot analysis of dystrophin after transplantation: No dystrophin was detected in the blank control group; in the 4 weeks after transplantation group, only few dystrophin expressions were detected, and the dystrophin/GAPDH was about 0.095?0.267; in the 12 weeks after transplantation group, dystrophin/GAPDH was about 0.218?0.338; dystrophin expressions were increased with time, at 16 weeks after transplantation, the expressions were much more than those at 8 weeks (dystrophin/GAPDH: 0.393?0.385, 0.173?0.284, t =6.062, P

Objective To explore the ultrasonic imaging features of malignant thyroid nodules risk fac-tors by logistic regression.Methods Two hundreds and forty patients with thyroid nodules by ultrasonic examina-tion and surgical treatment for patients with definited pathological diagnosis were included in this study.The pre-operative sonographic features of the nodules were put into the logistic regression model to explore the risk factors of ultrasonic imaging features of malignant thyroid nodules.Results By logistic regression model analysis,hypoe-cho,taller than wide≥1 and micro calcification were found to be significantly statistical variables for thyroid car-cinoma.Micro calcification could predict thyroid cancer for lymph node metastases.Conclusoin During clinical diagnosis,hypoecho,taller than wide more than 1 and micro calcification could be used as indicators by ultrasound doctors to judge malignant thyroid nodules and lymph node metastases.Prospective larger similar research is still very necessary to explore the indicator for thyroid carcinoma in the future.

Purpose To investigate the clinicopathological changes of the diffuse-type giant cell tumor of the bone and joint. Methods 42 cases of the diffuse-type giant cell tumor of the bone and joint were studied and the follow-up data were reviewed. Results The male patients were 19 and the female were 23, with the male to female ratio of 1 ∶ 1. 2. The age of the patients was 8~69 years (the average age was 37. 6). It was displayed that the patients presented local pain and swelling (34 cases), including dysfunction (18 ca-ses) of the bone and joint. Clinically, the lesions located on the knee joint ( 71. 4%) in 30 cases, the hip and ankle in 9 cases (21. 4%), and the wrist elbow in 3 cases (7. 1%). 27 cases were examined by MRI. Among them, the diffuse-type giant cell tumor was diagnosed in 9 cases (33. 3%). The effusive lesions of the joint presented in 5 cases, the non-specific synovial lesions and others in 3 cases. The obviously diffuse hyperplasia of synovial cells with nodular growth pattern was found. However, a high proliferative in-dex of the tumor cells and the rich-cell tumor were found. But there was no tumor necrosis. Histopathologically, the tumor cells of dif-fuse-type giant cell tumor contained marked brown pigments, multinucleated giant cells formation and a lot of lymphocytes proliferation or follicular reaction in 17 cases (40. 5%) with invasive growth and involvement of the joint and surrounding tissue. 6 cases recurred (20%) , including 2 cases with 2 times. Conclusions The diffuse type-giant cell tumors most commonly involve the knee, followed by the hip and ankle. Preoperative examination of MRI can be help for the diagnosis of the tumor. Histopathologically, diffuse-type gi-ant cell tumor with synovial cells rich-hyperplasia and the villous structures formation more likely recur. The main biological character-istics of diffuse-type giant cell tumor are invasive growth pattern, usually into the soft tissue around the joints.

OBJECTIVETo detect the expression level of interleukin 17 (IL-17) in the plasma and colonic mucosa of patients with ulcerative colitis (UC), and to explore the synergistic mechanism of qingchang huashi recipe (QHR) combined with Mesalazine.

METHODSRecruited were 24 mild or moderate UC patients of damp-heat inner accumulation syndrome (DHIAS). Their samples of intestinal tissues were histologically graded. They were assigned to the combination group and the Western medicine (WM) group, 12 in each group. Besides, another 12 healthy volunteers were recruited as the healthy control group. QHR combined Mesalazine were given to patients in the combination group, while those in the WM group took Mesalazine. The therapeutic course for all was 3 months. By the end of treatment the expression level of IL-17 in the plasma and colonic mucosa was detected using ELISA. The infiltration of IL-17 in the intestinal mucosal tissue was detected by immunohistochemical SP method.

RESULTSThe expression level of IL-17 in the plasma and colonic mucosa was significantly higher in UC patients than in healthy controls (P <0. 05). The higher the histological grading the higher the expression level. The expression level of IL-17 in plasma and colonic tissues decreased after treatment in the two treatment groups (P < 0.05). Besides, the expression level of IL-17 was lower in the combination group than in the WM group (P <0.05).

CONCLUSIONQHR combined Mesalazine could synergically enhance the effect and effectively inhibit intestinal inflammation through down-regulating the expression of IL-17.

OBJECTIVE: To observe the effects of Spleen- strengthening decoction on GLP- 1 in patients with type II diabetes. METHODS: A randomized double- blind placebo- controlled test was conducted, and through observations for 8 wks, the changes of the two patient groups in plasma glucose, HbA1c, plasma GLP- 1 and Glucagon as well as TCM symptom score were measured for comparison. RESULTS: Before administration of Spleen- strengthening decoction, the two groups showed no significant difference in all of the indexes. After administration, the treatment group recorded lower indexes in fasting plasma glucose, HbA1c and plasma Glucagon, but higher index in fasting plasma GLP- 1, with no significant difference seen in other indexes. CONCLUSIONS: Spleen- strengthening decoction can improve glucose metabolism through heightening fasting plasma GLP- 1, and lowering both Glucagon and fasting plasma glucose.

Objective Explore the individual difference in carbon monoxide (CO) poisoning and analyze whether females were be more resistant to CO poisoning.Methods We collected 207 cases of CO poisoning deaths, and then we analyzed the Carbonyl Hemoglobin (COHb) results sorted by different sources of CO.Results The source of CO had significant impact on the fatal COHb level, but gender was not significant in affecting COHb level. In addition, it is possible that children and elders were less resistant to COHb than adults.

A growing number of studies show that drug and non-drug means can be activated phosphatidyl inositol-3-kinase serine/threonine kinase(PI3K/Akt signaling pathway)in the beginning of reperfusion, and make its downstream fork protein transcription factor O3a (FoxO3a) phosphorylation, and then promote cell survival and reduce the apoptosis so as to alleviate the symptoms of myocardial ischemia.In this paper,the role of PI3K/Akt and FoxO3a effector in myocardial ischemia was reviewed, and illustrated the role of PI3K/Akt/FoxO3a signaling pathway in myocardial ischemia.

Objective To study the antigenicity of human thyrotropin receptor(hTSHR)amino terminus (amino acid 29～280)and its association with Graves' disease.Methods Total thyroid RNA was prepared from human normal thyroid tissue.RNA was then reversely transcripted and cDNA was subjected to PCR amplification.PCR product was cloned into pcDNA3.1 and the recombinant plasmid was named pcDNA3.1/hTSHR188～940bp. Balb/c mice were immunized with peDNA3.1/hTSHR188～940bp. The levels of serum thyroxin,anti-TSHR antibody(TRAb)and thyroid stimulating antibody(TSAb)were measured,and the pathological changes of thyroid tissue were also observed.Results A 753 bp fragment encoding hTSHR ectodomain amino end was obtained after PCR amplification.Confirmed by Hind Ⅲ restriction enzyme digestion and DNA sequencing,pcDNA3.1/hTSHR188～940bphad been constructed successfully,with the correct sequence and direction of hTSHR188～940bp.In the Balb/c mice treated with pcDNA3.1/hTSHR188～940bp,elevated TRAb in week 6(0.148±0.018)were observed compared with those at week o(0.106±0.006,P＜0.01),and kept a higher level till week 10(0.134±0.011,P＜0.01).T4 and TSAb index values were significantly increased in week 10.Serum T4 concentration increased from(41.02±7.97)μg/L in week 0 to(62.20±12.77)μg/L in week 10(P＜0.01);TSAb index values rose from 0.864±0.076 at week 0 to 1.392±0.615(P＜0.01).Thyroid pathological examination showed that proliferated thyroid follicular epithelial cells and foll icular eapacity increased.Inflammatory cells were occasionally found.Conclusions There are antigen epitopes in hTSHR ectodomain amino acid 29～280,which can stimulate the production of TSAb.And the latter induces hyperthyroidism and Graves' disease like manifestations.It suggests that hTSHR ectodomain amino acid 29～280 is closely associated with Graves' disease,and maybe one of important etiological factors leading to the disease.
