Objective To study the effect of glutamine and arginine in rats with hepatic fibrosis.Methods Thirty male Wistar rats with hepatic fibrosis induced by CCl4 for 6 weeks were randomly divided into control group(n=10)、glutamine treatment group(n=10) and arginine treatment group(n=10).At 8 weeks after treatment,the liver appearance、collagen protein level and the degree of hepatic fibrosis were observed.Results At the end of 8 weeks,there was no death of any group of the rats.The glutamine group showed the most severe hepatic fibrosis,the control group showed less,and the arginine group showed the least fibrosis.Conclusions The degree of hepatic fibrosis is aggravated by glutamine,while arginine obviously relieves rat hepatic fibrosis.

Objective To retrospectively analyze the clinical data of 16 patients with renal cell carcinoma complicatedwith sarcomatoid differentiation, so as to discuss the treatment and prognosis of the condition. Methods A total of 547 patients with renal cell carcinoma were admitted in our department during 2005-2009, and 16(2. 9%) ofthem also had sarcomatoid differentiation, including 7 males and 9 females, aged (52 ± 10) years old, ranging 36-70 years old. Gross hematuria was found in 5 patients, backache in 5, fatigue and weight loss in 2, cough and hemoptysis in 1; and 3 patients were accidentally found with renal occupation during physical examination. All tumors were solitary, with 7 in the left and 9 in right. The maximum tumor diameter was (7. 8±4. 1) cm, ranging 2-15 cm. Full examination was done to confirm the tumor stage preoperatively. Preoperative examination showed that 2 patients had retroperitoneal lymph node enlargement, 1 had right pulmonary hila lymphatic metastasis, 1 had livermetastasis, 2 had renal vein and (or) the inferior vena cava tumor thrombi, 3 had bone metastases, 1 had invasion of ipsilateral adrenal gland, and 1 had invasion of the upper ureter. All the 16 patients underwent surgical treatment,and their specimens were subjected to H-E staining and immunohistochemical examination. Five patients were treated with INF-α after operation and were followed up. Results All patients received radical nephrectomy. Pathological examination showedthat 9 patients had clear cell renal cell carcinoma with sarcomatoid differentiation, 3 had chromophobe renal cell carcinoma with sarcomatoid differentiation, and the other 4 had unclassified renal cell carcinoma with sarcomatoid differentiation. No recurrence or metastasis was seen in the 4 pT1N0M0 patients. All the pT2-T4 patients died, with the progression-free survival time being (5. 6±4. 5) months, ranging 2-16 months; the overall survival time was (8. 3± 5. 6) months, ranging 3-20 months. Conclusion Preoperation staging of patients with renal cell carcinoma complicated with sarcomatoid differentiation has a great impact on patient survival. Operation is the most effective treatment for patients with early stage, and routine follow? up examination is recommended post operatively. Targeted therapy may be an effective way for patients of advanced stag.

Abnormal activation of Wnt signaling pathway plays an important role in the development and progression of prostate cancer; androgen receptor (AR) is the key for the transformation of androgen-independent prostate cancer (AIPC), and AR signaling pathway is now the focus of prostate cancer research. Many signal pathways can affect AR signaling pathway; in this paper we review the Wnt signaling pathway, androgen receptor and their crosstalk in prostate cancer.

Objective To conduct targeted surveillance of nosocomial infections in intensive care units(ICU)to provide reference for comprehensive infection control . Methods All the 374 patients treated in ICU in 2013 were investigated by targeted surveillance methods .Results A total of 82 episodes of nosocomial infections were identified in 62 (16 .6% )of the 374 patients . The cumulative hospital stay was 2 724 days .The infection incidence per patient‐day was 22 .8‰ .The infection in ICU was primarily pneumonia (75 .6% ,including 39 ventilator‐associated pneumonia) ,bloodstream infections (including 6 central line‐associated bloodstream infections ) and catheter‐associated urinary tract infections . The incidence of ventilator‐associated pneumonia ,central line‐associated bloodstream infection and catheter‐associated urinary tract infection was 33 .3‰ ,2 .8‰ , 2 .3‰ patient‐day ,respectively .Overall ,74 strains of pathogens were isolated ,of which 93 .2% ,5 .4% and 1 .4% were gram‐negative bacilli ,gram‐positive cocci and fungi ,respectively .The top three gram‐negative bacilli were Pseudomonas aeruginosa(25 .7% ),Klebsiellapneumoniae(14 .9% ),and Acinetobacterbaumannii(10 .8% ).Conclusions Theincidenceof nosocomial infection was 16 .6 % in ICU patients ,of which device‐related infection accounted for 62 .2 % .Control of equipment‐related infections is critical for curbing the nosocomial infections in ICU . The antimicrobial regimens for ICU patients should cover gram‐negative bacilli .

[Objective]To study the role and the effect of establishing the plan of meeting emergency in the rehabilitation and reestablishment of high-octane body hurt.[Method]Eighty six patients of high-octane body hurt were collected from Shi He Zi people's hospital during 1998 to 2007.According to Gustilo-Anderson categorize of open fracture and mark of ISS,high-octane body hurt can be divided into three parts.Meanwhile,different part can be taken different methods to rehabilitate and reestablish.Therefore,we can analyze pertinence between cure principle and curative effect.[Result]Eighty three patients were observed during the period of fifteen and thirty-three months,the average were nineteen months.Five of them contracted double floating knee injury,and their knee joint appeared anchylosis,abnormality and function failure afterfracture healed up.We did one-off knee joint release while extracting internal fixation,and used CPM machine to assist exercise.Fortunately,the function of knee joint could be renewed.Another five patients' fracture did not heal up very well.However,after experiencing the apply of oneself bone autograft,fracture could be healed up perfectly.The time of allograft bone union ranged from five to sixteen months,the average time were 7.5 months.There are three patients contract paraplegia,and three patients dead.By autopsy,some of them belongs to multiple fracture and multiple viscera burst.Mortality was 3.48%.[Conclusion]By establishing the plan of meeting emergency of high-octane body hurt,using the Gustilo-Anderson categorize of open fracture and mark of ISS,we can systemic classify damage degree,and make scientific treatment by stages,therefore,attaining our goal of early diagnoses,early treatment,and decreasing mortality and decreasing the proportion of disabled.After all,the plan of meeting emergency plays an essential role in traumatie surgery.

[Objective]To detect the expression of tumor necrosis factor-?(TNF-?)and interleukin-18(IL-18)protein in herniated intervertebral disc,and discuss the role of TNF-? and IL-18 protein in the course of the intervertebral disc degeneration and to clarify the mechanism of the lumbar intervertebral disc degeneration and herniation. [Method]Forty nine specimens were studied from December 2005 to April 2007 in the First Affiliated Hospital of Shihezi Medical College.Experimental group contained thirty-four herniated intervertebral disc and control group contained fifteen discs,which were collected from the patients with spine fracture or autopsy.The specimens were divided into two parts,one part was fixed in 10% formalin about 24 hours and was embedded in paraffin.Four ?m serial sections and S-P method were used.The sections were stained with TNF-? and IL-18 monoclonal antibodies,and the results were observed by OLYMPUS microscope.Another part was changed into well-distributed liquid,which was determined by Elisa method respectively,in order to detect density of TNF-? and IL-18 protein.Software SPSS 13.0 was used for statistical analysis.[Result]1 TNF-? and IL-18 protein were expressed mostly in cytoplasma.The expression of IL-18 in the experiment group was obviously higher than in the control group.There were statistical significances(P

10 000mL. Six cases developed ascites postoperatively. There was no mortality or bile duct injury. The average hospital stay was 15d.Conclusions Intraoperative bleeding and bile duct injuries are the major dangers of (cholecystectomy) in patients with liver cirrhosis, and packing of gallbladder bed with pedicle of greater omentum is a satisfactory method of hemostasis.
