Objective To investigate the clinical efficacy of ultrasound-guided double-tract percutaneous cholecystostomy combined with choledochoscopic gallbladder-preserving cholecystolithotomy for the elderly patients with acute calculous cholecystitis.Methods The clinical data of 35 elderly patients with cholecystolithiasis who were admitted to the General Hospital of Chengdu Military Command from January 2012 to December 2013 were retrospectively analyzed.All the 35 patients received ultrasound-guided double-tract percutaneous drainage,and then received choledochoscopic gallbladder-preserving cholecystolithotomy.The long-term oral use of anti-inflammatory and cholagogue medications after operation reduced recurrence of cholecystolithiasis.All the patients were followed up by telephone interview and outpatient examination till June 30,2014.Results All the 35 patients undergoing successfully the ultrasound-guided double-tract percutaneous cholecystostomy.Of the 35 patients,1 patient with the puncture bleeding was cured successfully by symptomatic treatment,1 patient was treated by cholecystectomy due to the unformed sinus tract under costal margin,and other 34 patients underwent successfully cholecystolithotomy.The follow-up was carried out for 4 to 24 months and 1 patient was diagnosed as with recurrence of cholecystolithiasic.Conclusion Ultrasound-guided double-tract percutaneous cholecystostomy combined with choledochoscopic gallbladder-preserving cholecystolithotomy for elderly patients with acute calculous cholecystitis is safe and feasible,with an advantage of promotional value.

Objective To determine whether the cross-sectional area (CSA)of the calf measured with MRI could stage lower ex-tremity lymphedema (LEL)secondary to gynecological cancer treatments.Methods 148 patients were enrolled in this research.116 females with unilateral LEL and 32 without LEL after gynecological cancer treatments underwent calf MRI and water displacement. Total soft tissue CSA (T),muscle CSA (M)and subcutaneous tissue CSA (S)of affected calf,and difference of T (DT),M (DM) and S (DS)between calves were obtained on MRI at mid-calf level.Volume of affected calf and difference of volume (DV)between calves were obtained by water displacement.Statistical analysis was performed to determine feasibility of MRI measurements for ac-cessing LEL.Results There were close correlations between volume and T or S of affected calf,and between DV and DT or DS of calves.The correlations of stages of LEL with T and S of affected calf as well as DT and DS were stronger than the volume of affect-ed calf and DV (P< 0.01).Multivariate analysis showed more significant differences in T and S than in volume of affected calf,and in DS than in DV between LEL stages (P< 0.05).No difference was found in volume of affected calf and in DV between stage 0 andⅠ. For staging LEL,DS showed the most profound discrimination ability among all measurable parameters.Conclusion DS of calves could be the most reliable parameter recommended for staging and early diagnosis of LEL.

ObjectiveTo evaluate the applicability of modified formulas based on plasma creatinine levels in Chinese patients with chronic kidney disease (CKD). MethodsA total of 327 CKD patients were investigated. Glomerular filtration rate (GFR) was estimated with Chinese equations and Ruijin equation. The accuracy of estimated GFR was compared with 99mTc-DTPA-GFR (sGFR) in CKD patients. ResultsBland-Ahman analysis demonstrated that Ruijin equation was more consistent with sGFR than the other equations. But all the equations were not well consistent with sGFR. Linear regression showed that the slopes of Ruijin equation and MDRD-1 equation were closer to the identical line. 15%, 30% and 50% accuracy of Ruijin equation were higher than the other equations. But 30% accuracy of Ruijin equation was still less than 70%. When the accuracy of estimated GFRs was compared with sGFR in different stages of CKD, GFR estimated by Ruijin equation showed good results. ConclusionsWhen plasma creatinine is checked with enzymatic method, modified GFR estimation equations may show great bias in Chinese CKD patients. More clinical trails should be carried out to evaluate and identify the application of modified GFR estimation equations in Chinese patients with CKD.

Objective To investigate the clinical preemptive analgesic efficacy of parecoxib sodium(PS) at different administration timing in the patients with total hip arthroplasty(THA).Methods Sixty patients receiving THA were prospectively enrolled and randomized into three groups.The group A started to be intravenously injected by PS 40mg/d on preoperative 3 d until operation day;the group B was intravenously injected by parecoxib sodium 40mg at preoperative 30 min;the group C began to be intravenously injected by the same dosage of normal saline at the same time point as the group A.The rest pain was assessed by using the visual analog scale(VAS) at postoperative 6,24,48,72 h.The duration of patient-controlled intravenous analgesia(PCIA) and total dosage were recorded.The first time unaided ambulation time was observed.Results The VAS scores at various postoperative time points in the group A and B were significantly lower than those in the group C(P＜0.05),the VAS scores at postoperative 6,24 h in the group A were remarkably lower than those in the group B.The PCIA duration in the group A,B and C were 25.05±10.32),(36.75± 13.91),(50.40 ± 15.17)h,respectively,the pair-wise comparison of the group A,B and C showed statistical difference(P＜0.05).The total dosages of PCIA drug in the group A,B and C were(29.25 ± 4.58),(34.50 ± 5.09),(62.65 ±10.52)tg,respectively,the dosage in the group A and B was significantly lower than that in the group C(P＜0.05).The first time unaided ambulation time in the group A,B and C were (2.75 ± 0.81),(3.05 ± 1.08),(4.10 ±-0.92)d respectively,which in the group A and B was earlier than that in the group C (P＜0.05).Conclusion Continuously using PS on preoperative 3 d can increase the analgesic effect in THA patients and is conducive to the functional rehabilitation and increase the patient satisfaction.

Objective To present the baseline characteristics of serum uric acid level in patients with chro-nic kidney disease(CKD). Methods A cross-sectional study on CKD patients was carried out in our hospital for 9 months. Results 713 patients were enrolled. The top three causes of CKD in these patients were primary glomerular disease(61.2%, 436/713), essential hypertensive kidney disease (7. 2%, 51/713 ) and diabetic nephropathy (5.8% ,41/713). Serum uric acid level and the incidence of hyperuricemia were associated with the stage of CKD (F = 73. 569, P = 0. 000;χ2= 138. 156, P = 0.000). A significantly negative correlation was discovered between ser-um uric acid level and the level of glomerular filtration rate(RR = - 1. 045 ,P =0. 000). A significantly positive cor-relation of serum uric acid level was found with diastohc blood pressure, proteinuia level, smoking and BMI ( RR = 1.400,15. 149,37. 696,and 3.421 ,P <0.05 ,respectively). Conclusions The cross-sectional study of serum uric acid level in patients with CKD will help to determine the dynamic changes of serum uric acid level in Chinese CKD patients and lay a solid basis for the prevention and treatment of CKD and its complications.

Objective To analyze the impact factors for early renal damage in type 2 diabetic patients by the classification tree model.Methods A total of 601 patients with type 2 diabetes were enrolled.According to glomerular filtration rates and urine albumin quantification,the patients were divided into type 2 diabetes group (418 cases) and early diabetic renal damage group (183 cases).The clinical data of the patients were recorded to analyze the main influential factors for the microalbuminuria of type 2 diabetic patients using the Exhaustive CHAID classification tree algorithm.Results Six important explanatory variables were screened out by the classification tree model from the 34 candidate variables related to early renal damage,including fibrinogen,history of hypertension,retinopathy,Cys C levels,SBP and peripheral neuropathy.Elevated fibrinogen was the main factor.Conclusion The classification tree model can analyze the major influential factors of early renal damage in type 2 diabetic patients effectively,and it can help develop the prevention and treatment methods.

Objective To evaluate the MR lymphangiography (MRL)in diagnosis of limb lymphedema.Methods A total of 582 patients with lymphedemtous limbs were enrolled in the study,MRL was performed at 3.0T MR.The morphology and enhancement of the lymph nodes,the number of lymphatic vessels and the lymph flow were evaluated.Results No matter in primary or secondary lymphedema,there were patients showed only lymph nodes affected,or only lymph vessels affected,and some patients showed both affected.Lymphatic aplasia,hypoplasia or hyperplasia were showed in primary lymphedema.Obstruction lymphatic vessels,and lym-phangiectasia were showed in secondary lymphedema.The velocity of lymph flow was (1.0±0.62)cm/min in affected limb of pa-tients with primary lymphedema,which was significantly slower than that of affected limb of patients with secondary lymphedema (2.22±1.64)cm/min(P<0.01)in dynamic contrast-enhanced MRL.In both type of lymphedema,the contrast enhanced lymph nodes showed less nodes with delayed enhancement and lower signal intensity,compared to that of lymph nodes in the contralateral normal side.Conclusion Dynamic contrast-enhanced MRL is helpful for assessing the anatomical and functional status of lymphatic system in lymphedematous limb.This new imaging techniques provides a powerful tool for the diagnosis of lymphedema.
