Objective To observe the effects of mizoribine(MZR)on renal tubular epithelial?mesenchymal transition(EMT)of mice which have been performed unilateral ureteral obstruction(UUO),and study the mechanism of its anti?fibrosis of renal interstitial. Methods A total of 24 CD1 mice were randomly divided into sham group,UUO model group and MZR treatment group,with 8 mice in each group. The day before op?eration,mice of MZR treatment group had been given MZR 10 mg/kg/d lavage,those of sham group and UUO model group had been given equal saline lavage. Fourteen days after the operation ,blood was collected and serum creatinine and blood urea nitrogen were measured;the obstruction kidneys were harvested for section,HE staining and Masson staining were employed to observe the changes of kidney pathological;the expression ofα?SMA and E?Cad in kidney with detected by immunohistochemical and Western blot method. Results Compared with sham group,serum creatinine and blood urea nitrogen of mice in UUO model group and MZR treatment group were significantly elevated ,kidney pathological chang?es and the expression ofα?SMA in renal tissue were increased and that of E?Cad was reduced ,the differences were all statistically significant(P<0.05);compared with UUO model group,mice in MZR treatment group had different degree of improvements in serum creatinine,blood urea ni?trogen and kidney pathological changes ,the expression ofα?SMA in renal tissue was inhibited and that of E?Cad was increases ,and the differences were statistically significant(P<0.05). Conclusion MZR may inhibit the development of renal tubular EMT in UUO mice ,thereby reduce the level of renal tubule interstitial fibrosis and improve renal function.

Objective To compare the influences of different routes of nutrition on the outcome and respiratory muscle strength of elderly patients in respiratory intensive care unit (RICU). Methods Totally 147 elderly patients in RICU were equally randomized into combined nutrition group ( combinination of parenteral nutrition and enteral nutrition), total enteral nutrition (EN) group, and total parenteral nutrition (PN) group. The changes of energy metabolism, respiratory muscle strength, and short-term outcome were observed or determined.Results Plasma albumin (ALB), hemoglobin (Hb), creatinine (Cr) levels, and nitrogen balance significantly increased in all group 7 days later ( all P ＜ 0. 01 ), while blood urea nitrogen (BUN) significantly decreased ( P ＜0.01 ). The increase of ALB, Hb, Cr levels, and nitrogen balance were significantly more remarkable than that in EN group and PN group (P＜0.05 or P＜0.01). The decrease of BUN level in the combined nutrition group was significantly more remarkable than that in EN group ( P ＜ 0. 05 ). After nutritional support, the maximum inspiratory pressure in the combined nutrition group (P =0. 021 ) and EN group (P = 0. 011 ) became significantly higher, and occlusion pressure at 0.1 second inspiration level in the combined nutrition group became significantly lower ( P =0. 025). The incidences of infectious and non-infectious complications in PN group were significantly higher than those in EN group (P = 0. 002 and 0. 017, respectively) and combined nutrition group ( P = 0. 005 and 0. 004, respectively). Gastric retention was more common in EN group than that in PN group ( P = 0. 035). The weaning time,length of RICU stay, length of hospital stay and 20-day-mortality were significantly decreased in the combined nutrition group than those in the other two groups ( all P ＜ 0. 05 ). Conclusion The effectiveness of the combined application of PN and EN is superior to PN or EN alone in improving nutritional status and respiratory muscle strength as well as in improving the short-term outcome in elderly patients in RICU..

Objective To study the diagnosis,management and prognosis of persistent m?llerian duct syndrome (PMDS). Methods 2 cases of PMDS associated with transverse testicular ectopia were reported.Clinically there was azoospermia or testis tumor.Corporeal hysterectomy and orchidopexy were performed and the testis tumor was excised. Results Vascular supply and hormonal function of the testis were normal in both 2 patients after 2 year's follow up. Conclusions PMDS is an inherited male pseudohermaphroditism. Every effort should be made to preserve the testis and its fertility function when surgical management is needed.The possible development of testis tumor should be kept in mind and closely observed.

OBJECTIVETo analyze the imaging features of osteopoikilosis and its diagnosis knowledge.

METHODSThe imaging data of 9 patients with osteopoikilosis were analyzed retrospectively, including 6 familial cases and 3 sporadic cases. In 6 familial cases,there were 4 males and 2 females with an average age of 28 years old ranging from 10 to 63 years. Clinical manifestations of 1 familial case were left knee pain and limitation of activity for 3 years, and other 5 cases without clinical manifestation. In 3 sporadic cases, there were 2 males and 1 female with an average age of 33.7 years old ranging from 25 to 44 years. Three sporadic cases had obvious injury history with following up from 6 to 12 months. All imaging results of 9 cases were observed.

RESULTSThe imaging data of 6 familial osteopoikilosis showed the multiple round or oval nodes within bone with clear margins, uniform density, different size. The occurrence of the hyperostotic spots preferentially localized in the epiphyses and metaphyses of the long bones, and carpus and tarus. X-ray features of 3 sporadic osteopoikilosis were similar to that of 6 familial cases and for 6 to 12 months follow-up X-ray features were unchanged.

CONCLUSIONThe imaging features of osteopoikilosis are relatively specific such as the multiple mottling dense focal within bone with clear border and bilateral symmetry, and the focus located on cancellous bone and the diaphyses usually is unaffected. The imaging is a valuable examination for the accurate diagnosis of osteopoikilosis.

Atomic force microscopy has become an important tool for studying biological samples based on its high spatial resolution, high force resolution and the capability of working at physiological conditions. This article reviewed the application of AFM imaging and force measurement in biology and medicine.

OBJECTIVE:To provide electronic drug directions for hospital staffs.METHODS:Based on the military hospital information system,a system that can provide electronic drug directions was developed by establishing the database,collecting and sorting drug directions.RESULTS&CONCLUSION:This system is characterized by friend user interface,convenient input,quick inquiry,easy maintenance and widespread service,which can help hospital staffs to get the drug di?rections quickly and exactly and hence to better serve patients.
