Objective To improve the diagnosis of multiple tuberculosis of bone and joints by analyzing its radiologic findings respectively .Methods 5 cases with multiple tuberculosis of bone and joints were all proved by pathology of them, there were 1 male and 4 female, the age ranged from 15 to 56 years old. X-ray films were all taken in 5 cases. Vertebral canal iodolography was performed in 1 case, 2 cases were undergone biopsy, and operation was done in 3 cases.Results Multiple bones in 5 cases were involved, including 3～5 bones. Of all cases, long bone and short bone were involved together in 3 cases, plat bone and vertebra were involved together in 1 case, long bone, plat bone and vertebra were simultaneously involved in 1 case. And 3 cases involved long bone and short bone simultaneously had pathosis in unilateral limbs, 2 cases involved plat bone had pathosis in bilateral. X-ray plain films demonstrated osteolytic destruction with slight sclerosis at the margin of partial destructive areas, which were round, oval or irregularity. There were soft tissue masses around the involved bones.Conclusion The multiple tuberculosis of bone and joint is of some clinic symptoms and X-ray features, but the confirmed diagnosis of which is entertained by biopsy and pathology.

OBJECTIVE:To investigate the curative effects of alfacalcidol soft capsules combined with calaium carbonate tablet on secondary hyperparathyroidism(SHPT)associated with chronic renal failure(CRF).METHODS:55patients were assigned to dialysis group(28cases)and non-dialysis group(27cases),both groups had taken oral alfacalcidol soft capsules in combination with calcium carbonate tablet continuously for3months.Then the changes in serum Ca 2+ ,P 3- ,PTH,AKP and Cr levels were observed.RESULTS:After treatment,serum Ca 2+ concentration was significantly increased(P

Objective To evaluate the value of breast molybdenum target radiography in evaluating the enlarged axillary lymph nodes in breast diseases.Methods 79 patients underwent breast molybdenum target radiography,including conventional laxial and oblique projection. Some of them were examine furtheremore in compress projection in axillary fossa. The X-ray findings were analysis. And radiologic-pathologic correlation were carried out.Results There were 46 cases of brease carcinoma, 20 cases of hyperplasia,7cases of fibroadenoma,2 cases of plasmacytic mammitis,2cases of lipoma and 2 cases of papilloma in 79 patients. In the 33 cases of breast benign lesion , the enlarged axillary lymph nodes were seen bilaterally in 12 cases, sum was 1 to 5 in each case, smaller than 2 cm in diameter in 31 cases and uneven density in 13 cases were showed. In the 46 cases of brease carcinoma, the enlarged lymph nodes were seen laterally in 43cases, sum was 1 to 4 in each cases, larger than 2 cm in diameter was showed in 17 cases, and all were even density. There were statistical differences in number, diameter and density of enlarged lymph nodes between two groups. Conclusion The enlarged axillary lymph nodes are of different X-ray features in breast benign lesion and malignant lesion,it is helpful in differential diagnosis of breast diseases.

Objective To study the value of double contrast barium enema(DCBE),colonoscopy and spiral CT in examination of colonic disease.Methods 325 cases with colonic disease underwent DCBE,colonoscope and CT examinations.The detecting rates and the accurate rates in localizing the lesions were compared among these three examinations.Results The detecting rate of lesions by DCBE,colonoscope and CT were 91.1,89.8 and 64.6,respectively,there was no statistical difference between the former two,but there was difference between the former and CT(P

Objective To analyze the mammographic features and pathological characteristics among different molecular subtypes of breast cancer.Methods The results of 210 cases breast cancer identified by postoperative pathology were collected and classified to three groups;Luminal,HER-2(+)and TNBC(triple negative breast cancer)by molecular subtypes.Three groups'mammograph-ic features and pathological characteristics were compared.Results 210 cases included 147 Luminal cases,30 HER-2 (+)cases and 33 TNBC cases.There were statistically significant difference between tumor grading and lymph node metastasis (P <0.05).Three groups had statistically significant difference among mass number,mass margin and calcification incidence(P <0.05),and had no sta-tistically significant difference between mass size and shape(P >0.05).The mammographic features of Luminal molecules subtypes showed more mass with burr,HER-2(+)molecules subtypes showed no fixed features but more calcification incidence than other groups,TNBC molecules subtypes showed merely mass with clear margin and less calcification.Conclusion The mammographic fea-tures and pathological characteristics of different molecular subtypes of breast cancer are significant differences.

SAαt2,6 and SAα2,3 linked sialic acid molecules on epithelial cell membrane served as receptors for influenza virus, which axe specifically recognized by human and avian influenza viruses, respectively. The distribution of these two species of sialic acids in human respiratory tract from different anatomical sites and different age groups was investigated. The results showed that SAα2,3Gal species was prevalent in respiratory bronchiole and lung alveolar epithelium, but was infiequent in trachea, bronchus and bronchiole. On the contrary, the SAα2,6Gal species was more common in the trachea and bronchus and to a lesser degree in the alveolar epithelium. When compared the expression levels of SAα2,6Gal and α2,3Gal in the respiratory tract among different age groups, no significant difference was found. In the ex vivo H5N1 virus infection study, alveolus epithelium were found to be more susceptible to avian influenza than trachea and bronchus epithelial cells. These results suggest that the human respiratory tract, to some extent, is permissive for avian influenza viruses. The currently-observed limited human to human transmission of H5N1 virus may be associated with the different abundance of SAα2,3Gal linkages in human upper respiratory tract among individuals.

Objective To explore the optimized method of venous anastomosis for right donor kidney transplantation in rats.Methods Sprague Dawley (SD) rats were used as donors and recipients for homologous rat kidney transplantation.Both bilateral kidneys were harvested from the donor rats (n =45).Ninety rats were used as recipients and divided into 4 groups according to randomly digital table:In groups AC (n =15 each),the right donor kidneys were transplanted into the left nephridial pit of recipients,and endto-side,venous bypass and modified end-toend (donor's proximal end of vena cava was anastomosed to recipients renal Vein followed by ligation of its distal end) venous anastomosis was done,respectively; In the control group (n =45),the left donor kidneys were transplanted into the same side of the recipients,and the conventional end-to-end venous anastomosis was used.Then the intra-operative findings,successful operation rate and postoperative complications were compared between two groups.Results The venous anastomosis time in group B was longer than in groups A,C and control group (P＜0.05),which significantly increased warm ischemia time of donor kidneys and operative time of recipients (P＜0.05).The venous anastomosis time,warm ischemia time of donor kidneys and operative time of recipients showed no significant difference between groups A or C and control group (P＞0.05).The successful operation rate in group C (93.3％)was similar to that in control group (86.7％) (P＞0.05),but higher than in group A (53.3％) and group B (53.3％) (P＜0.05).There was no significant difference in postoperative complications between group A and group C.Conclusion For right donor kidney transplantation,the method of harvesting the right donor kidney with a part of vena cava,and then anastomosing the proximal end to recipients renal vein and ligating the distal end,is highly feasible,efficient and economic.
