Based on the development trend of the three -in-one system of “medical treatment, teaching and scientific re-search”, the main university affiliated hospitals at home and abroad need to ensure the sustaining development of hospital scientific re-search and improve the core competitiveness of hospital by improving the scientific research management , such as focusing more atten-tion on the scientific research policy , improving the quality of management staff , constructing the diversification mechanism , integra-ting resources, constructing information platform, managing the funds and archives, and strengthening the whole process supervision.

The paper analyzes different expressions of indirectly associated strong-weak connection in the process of biomedical literature knowledge discovery,defines the effect and function of strong-weak connection on literature knowledge discovery,and indicates that the accuracy rate of the discovery of potential connection through strong connection is obviously higher than the accuracy rate obtained through weak connection,and strong connection can serve as an important factor for improving the application effect of literature knowledge discovery.

Objective To analyze the correlationship of ACE I/D gene polymerphisms with the anti-hypertensive efficacy of irbesartan among essential hypertension (EH) patients in Yunnan han people.Methods One hundred EH patients hypertension were treated with irbesartan 150mg once daily for 4 weeks,and anti-hypertensive efficacy were monitored during the treatment.Results There was a significant difference between anti-hypertensive efficacy of irbesartan among different genotype groups,DD group ＞ID group ＞Ⅱ group (P ＜ 0.05) Conclusions There is different therapy responsiveness in diffenent genotypes.ACE I/D polymorphism may be an important hereditary factor that impacts the efficacy of irbesartan.

Objective To assess the feasibility and clinical efficiency of laparoscopic Madigan enucleation of the prostate for the treatment of benign prostatic hyperplasia (BPH) with large prostate.Methods From Nov.2008 to Jan.2010,24 eases of BPH patients with large prostate ( ＞90 g) were treated in our institute by laparoscopic Madigan enucleation.The average patient's age was 65.2 yrs,the average prostate weight were 132.3 ± 21.9 g,preoperative residual urine was 143.2 ± 23.2 ml,average IPSS was 28.6 ± 3.8,average QOL was 5.5 ± 2.4 and average MFR was 5.4 ± 2.3 ml/s.All patients accepted the laparoscopic Madigan enucleation of the prostate.The pre-surgery and three months post-operative IPSS,QOL,and MFR were compared and analyzed.Results All 24 patients successfully completed the surgery.The resected prostate tissue weight was 104.7 ± 23.3 g,blood loss was 112.5 ± 47.8 ml,postoperative hospital stay was 3.5 ± 0.8 d,bladder irrigation time was 1.3 ± 0.9 d,drainage time was 2.3 ± 0.5 d and catheterization time was 3.1 ±0.4 d.Three months after surgery,patient's IPSS was 4.5 ± 1.8,QOL was 19.9 ±3.1,and MFR was 18.5 ±2.9 ml/s.All the parameters significantly improved compared with the pre-surgery data ( P ＜ 0.05 ).Conclusions Laparoscopic Madigan enucleation of the prostate is a safe and effective method in the treatment of BPH with large prostate volume.

Objective To investigate the clinical features,diagnosis and treatment of prostate sarcoma. Methods19 cases of prostate sarcoma had been treated in our hospital from Oct 1995 to Sep 2010,aged from 16 to 48 years (mean,36 years).They were hospitalized due to different degrees of difficulty in urination,6 cases with bladder irritation,3 cases with gross hematuria,3 cases with blood clots in urination,3 cases with difficult defecation,2 cases with urinary tract infection,and 1 case with low back pain.Digital rectal examination showed prostate volume increased significantly in 16 cases,of which 6 cases prominent into bladder,and 3 cases touched hard nodules and tenderness.B ultrasound examination showed prostate neoplasms with internal echo uneven.Pelvic MRI in 12 cases indicated irregular soft tissue density in prostate with unclear edge,a high-low mixed signal inside,and mass protruding outward,among which 7 cases with significantly enlarged prostates and unclear bladder boundaries,6 cases with unclear boundaries with rectum,and 1 case with solid and cystic change. Pelvic CT in 10 cases showed irregular prostate tumors,among which 5 cases with tumor violation of bilateral seminal vesicle,2 cases with tumor invasion of unilateral seminal vesicle,and 3 cases with lymph node enlargement.Chest X-ray in 2 cases showed widespread metastatic lung. Results Different treatments were used according to different conditions:6 cases with full cystoprostatectomy,8 cases with radical prostatectomy,1 case with skin routine ureter fistulization and rectal fistulization,1 case with bladder fistulization,1 case with chemotherapy after prostate biopsy,and 2 cases with prostate biopsy alone. Pathological diagnosis showed 6 cases of leiomyosarcoma,6 cases of rhabdomyosarcoma,2 cases of malignant mesenchymal tumor,1 case of phyllodes sarcoma,1 case of granulocytic sarcoma,1 case of phyllodes sarcoma,1 case of malignant fibrous tissue sarcoma,and 1 case of poorly differentiated muscle induced sarcoma. Immunohistochemical examination in 19 cases of paraffin specimens stained with SP showed vimentin was positive,smooth muscle actin and myoglobin in leiomyosarcoma and rhabdomyosarcoma were positive respectively,and desmin in two kinds of afore-mentioned sarcoma expressed in different level.CD117 and S-100 were weakly positive in 1 patient with undifferentiated component and 1 patient with liposarcoma of the malignant mesenchymoma.Peroxidase was positive in granulocytic sarcoma,p63 was positive in lobulated sarcoma,and CD34 was positive in malignant fibrous histiocytoma.14 patients were given chemotherapy,among which 6 cases were combined with radiotherapy.19 cases were followed up for 4 -30 months (mean 13 months).4 patients survived for 24 -30 months without recurrence,while 15 cases died within 18 months after diagnosis. Conclusions The prostate sarcoma is a clinically rare malignant tumor with high degree of malignancy and unspecific clinical manifestations.The diagnosis relies on biopsy and immunohistochemistry,and early diagnosis and radical surgical excision are helpful for increasing survival rate.

Objective To analyze the characteristics of bone scintigraphy in 117 cases with primary hyperparathyroidism (PHPT).Methods Of these 117 cases (50 males and 67 females),there were 116 parathyroid adenomas and 1 parathyroid cancer.Mean age was 61.1(12-86) years old.All had ~(99)Tc~m-methylene diphosphonate (MDP) bone scintigraphy.The bone images could be classified into 4 categories.Category Ⅰ:normal;category Ⅱ:localized abnormal,which could be subcategorized as Ⅱ A with skull and mandible involvement,and Ⅱ B with Ⅱ A characteristics plus metabolic derangement;category Ⅲ:systemic,whole-body incmased tracer uptake;category Ⅳ:systemic plus localized metabolic derangement.Data were analyzed statistically with X~2 and t-test (isolated samples).Results According to the scintigraphic findings,there were 47 cases(40.17%)of category Ⅰ,35 cases(29.91%) category Ⅱ (21/35cases Ⅱ A and 14/35 cases Ⅱ B),30 cases (25.64%) category Ⅲ,and 5 cases (4.27%) category Ⅳ.Combining categories Ⅱ、Ⅲ and Ⅳ together,there were 70 abnormal cases.These patients had history of abnormal bone images such as bone fracture (39 cases,55.71%),calculus (8 cases,11.43%),bone fracture plus calculus(7 cases,10.00%),osteoporosis (51 cases,72.86%) or ostalgia(26 cases,37.14%);however,in the 47 cases of category Ⅰ,only 1 (2.13%),0,0,10(21.28%)and 10 cases (21.28%),respectively,were found.Therefore.these case history characteristics were statistically significant (X~2=11.152,P=0.01).The tumor size,parathyroid hormone (PTH),blood calcium,blood phosphorus in the patients of abnormal PHPT categories Ⅱ to Ⅲ were(14.52±13.72)cm~3,(731.67±618.40)ng/L,(3.05±0.29) mmol/L and (0.71±0.14) mmol/L,respectively.with statistically significant difference compared to category Ⅰ:(0.78±1.33) cm~3,(112.04±62.98)ng/L,(2.56±0.42) mmol/L and (1.03±0.36)mmol/L(t=-5.724,-5.741,-7.274 and -6.451;all P＜0.01).Conclusions (1)Bone scintigraphy was normal in 40% of PHPT patients.(2)The bone images of PHPT could be classified into 4 categories and each could reflect the duration and severity of the disease status on bone.(3)The bone imaging characteristic could be useful for differential diagnostic purposes.
