Objective To discuss the key points of nursing care for patients using ultrasound-guided microwave coagulation therapy with artificial pleural effusion for liver carcinoma in the hepatic dome.Methods The preoperative and postoperative data of 34 patients who were hospitalized in our hospital from June 2004 to February 2009 were reviewed.Results All the patients finished the treatment successfully.Slightly chest distress was the most frequently complication correlated to artificial pleural effusion,mostly disappeared in 3-7 days.Only 3 patients suffered from dyspnea and a decrease of SpO_2 in the second day after the treatment.The symptoms were relieved after a drainage of pleural.The common side effects of microwave coagulation therapy were found as fever,pain during deep respiration and liver dysfunction,which were relieved after symptomatic treatment and nursing care.No severe complication was found.Conclusions Adequate preoperative preparation,proper intraoperative cooperation,close postoperative observation and nursing are the key points to decrease complications.

Objective To observe the dyskinesias and motor fluctuation in patients with Parkin-son’s disease, and investigate their influential factors. Methods The detail information of dyskinesias and motor fluctuation of 63 patients with Parkinson’s disease were recorded and followed up when the of L-Dopa therapy was carried out, and all patients were assessed by using UPDRS at “on” and “off” stage, Hoehn and Yahr scale, Schwab and England living scale.The data were calculated with SPSS 10.0 statistic software. Results All patients received alone or combined L-Dopa therapy.Among the 63 patients, 11 (17.5%) were experienced dyskinesias, in which 10 show dystonia; and 36 were (57.1%) experienced motor fluctuation, in which 28 developed wearing-off.The mean daily dose of L-dopa and score of UPDRS in “off” stage were positively correlated with dyskinesias.The duration of therapy with L-dopa was positively correlated with motor fluctuation.The controlled release cabidopa/levodopa was in negative correlation. Conclusions The rate of motor fluctuation was approximately equal to the results reported in other countries.The dyskinesias was lower in occurrence and the mean daily dose of L-dopa and the disease severity should be the main influencing factors to the dyskinesias.The duration of therapy with L-dopa should be influencing factor to motor fluctuation.The main subtype of motor complications should be dystonia and wearing-off.

OBJECTIVE: To study the hospital infections caused by ESBLs-producing Escherichia coli and Kalispell.METHODS: Bacterial drug resistance of 460 stains of ESBLs-producing Escherichia coli and Kalispell pneumonia and the application of antibiotics in our hospital in 2005 were analyzed retrospectively.RESULTS: The infections caused by ESBLs-producing Escherichia coli and Kalispell pneumonia were more often found in department of respiratory diseases,ICU and neurosurgery patients,which were treated empirically predominantly with levofloxacin,followed by cefoperazone/sulbactam,but were treated mostly by carbapenems,levofloxacin,cefoperazone/sulbactam after the drug susceptibility test results were obtained.The drug combination was characterized predominantly by combined use of two kinds,at most 6 kinds in combination.CONCLUSION: In most of the cases the medication for infections caused by ESBLs-producing Escherichia coli and Kalispell pneumonia is effective and reasonable.However,in a few cases the application of antibiotics is irrational and nonstandard,which should be given fully attention.

Objective To investigate the efficacy and safety of carvedilol in patients with chronic heart failure (CHF).Methods Forty-six patients with CHF were randomly divided into carvedilol group (n=26) and control group (n=20) on the basis of standard therapy including digitalis, diuretics and ACEI. Before and after treatment, NYHA class, echocardiography and adverse reaction were observed. Results The mean dose of carvedilol was titrated to 25.14?3.05mg/day. After treatment, NYHA class was improved in both groups. Left ventricular end-diastolic diameter (LVEDD) measured by echocardiography reduced [(58.79?8.99)mm vs (64.68?10.12) mm,P

BACKGROUND:Many internal fixations,such as dynamic hip screw,Gamma screw,proximal femoral nail,angle steel plate,as well as locking proximac femoral plate,are utilized in treating intertrochanteric fractures,especially the dynamic hip screw However,the failure rate is gradually increased.OBJECTIVE:To explore the application and clinical efficacy of total hip replacement for the treatment of elderly intertrochanteric fracture fixation after failure of dynamic hip screw.METHODS:A total of four cases with intertrochanteric fractures were treated by total hip replacement after failure of dynamic hip screw fixation was selected.According to Evans typing,one case were type Ⅱ,two cases were type Ⅲ A,and one case was typeⅢB.Internal fixation displacement could be found at half to 1 year after dynamic hip screw fixation.Because of bone disunion,coxa adducta and pain,the patients could not walk.Sequentially,total hip replacement was performed with 45°abduct angle and10°-15°anteversion angle The clinical efficacy was evaluated by Harris scoring criteria.RESULTS AND CONCLUSION:All the cases were operated smoothly,with 1.5-2 hour operation duration and 400-600 mL blood loss.No case appeared allergic response to bone cement.By 3-12 months follow-up,4 successful operative cases do not appear prosthesis loosening,subsidence and are satisfied with well hip function.The average Harris score were 81 points.The results revealed that application of total hip replacement after the failure of DHS in elderly intertrochanteric fracture fixation,which shortened the time patients stay in bed to reduce complications and improved the hip joint function.

Objective To investigate the effect of exercise on calcium modulin in myocardial sarcoplasmic re-ticulum of animal type 1 diabetes model in rat. Methods A total of 40 Spragne-Dawley rats were randomly dividedinto 4 groups : a normal control group, an exercise training group, a diabetes group and a diabetes plus exercise-traininggroup. At the end of 4- week-exercise training after the establishment of the diabetes model by intraperitoncal injectionof sterptozotocin, the animals were sacrificed and the level of blood glucose, insulin, blood fat and glycosylated serumprotein were tested. The gene expression of calcium modulin proteins was measured by reverse transcription-polymerasechain reaction, and the Western blotting technique was used to measure the protein of sarcoplasmic endoplasmic reticu-lure Ca<'2+> -ATPase (SERCA2) and phaspholamban (PLB). Results The level of biochemical indicator of exercisegroup is not affected when comparing with that of the control group, but significantly changed in diabetic group ( P <0. 01 ) ; The level of blood glucose, insulin, blood fat and glycosylated serum protein were ameliorated in diabetic rats inthe exercise training group. No significant changes in mRNA level of SERCA2, PLB and ryanodine receptor type 2(RYR2) were observed between control and diabetic group, the same to protein expression of SERCA2 and PLB. Butexpression of calcium modulin mRNA was significantly increased in exercise group and diabetic rats in the exercisetraining group comparing with that of the control and diabetic groups ( P < 0.01 ), the same to protein expression ofSERCA2 and PLB. Conclusion Exercise exerted good protective effects on the myocardial injury with 1 type diabetesrat, which might attribute to the upregnlated expression of SERCA2, PLB and RYR2 in diabetic rat heart.
