BACKGROUND:The function was poor in middle aged and elderly patients with total knee replacement. If there was no ideal anesthesia during the operation, the prognosis of patients would be poor. Therefore, it is necessary to explore the analgesic drugs for artificial knee joint arthroplasty. OBJECTIVE:To investigate clinical analgesic efficacy of tramadol and paracetamol in total knee arthroplasty and the drug safety. METHODS:200 cases undergoing unilateral total knee arthroplasty in the Department of Orthopedics of Huaian First Hospital Affiliated to Nanjing Medical University from December 2013 to January 2015 were enroled in this study. According to the different methods of analgesia, patients were divided into control and experimental groups, with 100 cases in each group. Control group received intravenous patient controled analgesia. Experimental group received paracetamol and tramadol oraly. Clinical analgesic efficacy and safety of tramadol paracetamol in total knee arthroplasty were analyzed. RESULTS AND CONCLUSION: No significant difference in visual analogue scale score was detected immediately, 4 and 5 days after replacement in both groups. Visual analogue scale score was significantly lower in the experimental group than in the control group at 1-3 days after replacement. Hospital for Special Surgery scores at 7 and 12 months after replacement and Special Surgery scores at 24 and 72 hours after replacement were significantly higher in the experimental group than in the control group. The twice doses of tramadol and paracetamol were significantly lower at 24 and 48 hours after replacement in the experimental group than in the control group. The incidence of complications was significantly lower in the experimental group than in the control group. These data verify that during perioperative analgesia, the effects of tramadol and paracetamol were ideal, could lessen patient’s pain, contribute to the recovery of knee function, have less adverse reactions, and have a certain clinical application value.

Dilated cardiomyopathy (DCM) is the most common type of cardiomyopathy in children.It is associated with gene mutation,viral infection,autoimmunity,nutritional deficiency,drug induced,endocrine and metabolic abnormalities,et al.Through the balance of the calcium content,the negative control of renin-angiotensin-aldosterone system and the reduction of the formation of inflammatory mediators,vitamin D can reduce the occurrence of DCM.This paper elaborates the latest research advances of the DCM pathogenesis and treatment,especially focusing on the mechanism and prognosis of vitamin D deficiency and gene mutation.

Government Subsidized Student Loan is a policy adopted by the government,which aims to help the poor students to go to college.However,the result turns out that the policy doesn't achieve the expectant target for many reasons.This paper analyses the reasons and introduces three methods for promoting the healthy development of the Government Subsidized Student Loan.They are: establishing the personal credit system for college students,ensuring the remedy right of loan and designing reasonable procedure of Government Subsidized Student Loan.

Objective To analyze clinical value of enteral nutrition via a nasojejunal feeding tube placed endoscopically and total parenteral nutrition in severe acute pancreatitis( SAP) .Methods 35 patients with SAP were received nasojejunal enteral nutrition endoscopically(NENE),while other 35 patients were received total parenteral nutrition(TPN).After nutrtion support for 4 weeks the nutrition index,Ranson score,APACHE score and CT score and complications and mortality rate of occurrence between the two groups were compared.Results After nutrition support of 4 weeks,the levels of hemoglobin and serum albumin of NENE group were (108 ±21) g/L,(38.7 ±9.5) g/L, which were significantly higher than those of TPN group( t=3.928,3.684,all P<0.05),while the fasting blood glucose of(5.1 ±1.2)mmol/L was significantly lower than that of TPN group(P<0.05),the level of CRP,TNF-α, IL-1 and IL-6 in patients of NENE group were (32.1 ±12.3)mg/L,(34.4 ±12.3)ng/L,(22.4 ±11.3)ng/L, (32.4 ±11.3)ng/L,which were significantly lower than those of TNP group(t=3.927,4.925,4.258,4.825,all P<0.05);the incidence of multiple organ dysfunction,hyperglycemia of NENE group were 17.14%,8.57%,5.71%, 5.71%,which were significantly lower than those of TPN group(χ2 =4.167,4.529,5.082,4.926,all P<0.05). Conclusion Nasojejunal enteral nutrition endoscopically is safe in clinical application.Compared with TPN,NENE results in better control of the incidence of complication, and decreased the length of stay in hospital and the cost enteral nutrition were more beneficial than total parenteral nutrition.
