Objective To investigate the clinical effects of liver transplantation including living related liver transplantation for Caroli's disease (CD). Methods Seven consecutive patients with diffused type of Caroli's disease had undergone liver transplantation (LT) from September 1999 to February 2007 in our single center. The clinical characteristics and survival of these patients were retrospectively reviewed. Results All 7 patients were diagnosed as Caroli's disease with diffused type which manifested recurrent cholangitis in clinical symptoms. Among them, 4 were female and 3 male.The mean age was 16 years old (ranging from 10 to 31 years old). Six patients were subjected to conservative therapy and only one patient had previously undergone cholecystectomy and T tube drainage before transplantation. In types of surgery, 4 patients accepted split liver transplantation with right liver lobe, two got whole liver transplantation and only one underwent living related liver transplantation. In two patients venovenous bypass was done during the operation. The mean duration of surgery was 9. 1 h. Post-transplant complications included pulmonary infection (3 cases), acute rejection (2 cases), pleural effusion (2 cases) and biliary leakage in the split section of donor liver (1 case). One patient died within 19 days caused by acute renal failure and multiple organs dysfunction.The rest six patients are alive without any signs of recurrence of protopathy and the longest survival time is 7 years. Conclusion Liver transplantation is a valuable treatment to Caroli's disease with diffused type. Due to the organ shortage, living related liver transplantation may own identical effects on LT.

We present a case of 32-year-old male with profound mental retardation and autism spectrum disorder who had presented with seizures, rigidity and elevated creatine kinase and was initially diagnosed as neuroleptic malignant syndrome (NMS). The patient subsequently had a complicated clinical course, developing refractory status epilepticus, which lead to the eventual diagnosis of progressive encephalomyelitis with rigidity and myoclonus (PERM). We discuss the clinical similarities and differences between NMS and PERM, and highlight the need to consider alternative diagnoses when the clinical picture of NMS is atypical, particularly in this patient group where the history and clinical examination may be challenging.

Objective:To evaluate the safety and efficacy of endoscopic cryoablation (ECA) in patients with upper tract urothelial carcinoma (UTUC).Methods:The clinical data of 9 patients with UTUC treated with ECA from April 2018 to September 2019 were retrospectively analyzed. Patients consisted of 3 males and 6 females, with median age of 76 years old (ranging from 50 to 88 years old). Among the patients, 6 cases had tumors of ureter, 1 case had tumor of renal pelvis and 2 cases had tumors of renal pelvis combined with ureter. Of the 9 patients, two had bilateral UTUC, six were presented with single lesion, three were presented with multiple lesion. The size of tumors were (1.53±0.91)cm. The tumors of all cases were localized (≤stage T 2), and there was no carcinoma or suspicious lymph node/distant metastasis. All patients enrolled in this study had strong will to choose kidney-sparing therapy. Biopsy, resection of intraluminal lesion with laser and cryoablation under ureteroscopy or percutaneous nephroscopy was performed under general aneasthesia.Ureteroscopy was performed 3 months after cryoablation. Perioperative complications and follow-up results were recorded and assessed. Results:Cryoablation was successfully performed in patients under ureteroscopy (n=8) or nephroscopy (n=1). The median cryoablation time was 6 (ranging from 4-16) minutes. The median follow-up was 16 months (ranging from 4-24 months). No tumor recurrence was observed at primary sites during follow-up. Two patients with multiple lesions were observed denovo ureteral neoplasms outside the primary sites 3 months and 6 months after cryoablation and treated with second cryoablation. One case died due to cardiovascular events 4 months after surgery. One patient underwent ureteral stricture during follow-up and received ureteroscopic balloon dilatation. No recurrent stricture was found in this case during the subsequent follow-up of 16 months. The other 5 cases showed no recurrence or complications like stricture during follow-up.Conclusions:ECA could probably be a promising treatment for localized UTUC. No recurrence in primary site and low incidence of ureteral stricture was observed during follow-up. The efficacy and safety of ECA need to be verified with large sample study.

Objective To evaluate the suitability of reported standard liver volume formulae for Chinese adults based on the practice of 216 cases of living donor liver transplantation in our transplantation center. Methods The graft volume was preoperatively estimated in 179 adult-to-adult right liver living donors by two methods: first, the radiological right liver volume by computed tomography (CT) and second,calculated graft volume obtained by reported standard liver volume formula and the percentage of the right liver volume ( given by CT). Both results were compared to the actual graft volume measured during surgery.Results The mean percentage of right liver volume was 55.4% (SD 5.41%). The results of Urata、Heinemann、Vauthey、 Lee、 Yoshizumi formula were significantly larger than the actual right liver volume (P ＜0. 01 ). The result of Sheung-tat Fan was less than the actual right liver volume, there was statistical ESLV =334. 024 + 11. 508 × BW, is most suitable to estimate adult Chinese donor's right liver volume.

OBJECTIVE:To establish a method for the content determination of polymer in cefatrizine propylene glycol. METHODS:High performance sephadex gel chromatography was performed on the column of Sephadex G-10 with mobile phase A of 0.01 mol/L phosphate buffer [0.01 mol/L Disodium hydrogen phosphate solution-0.01 mol/L Sodium dihydrogen phosphate solution (61∶39,V/V)](pH7.0)and mobile phase B of water at a flow rate of 1.0 ml/min,the detection wavelength was 254 nm,column temperature was 30℃,and volume injection was 200μl. RESULTS:The linear range of polymer was 2.07-103.30 mg/ml(r=0.999 4);the limit of quantitation of 10.4 ng,limit of detection was 4.1 ng;RSDs of precision and reprodicibility tests were lower than 3%. CONCLUSIONS:The method is specific with high sensitivity and good reproducibility,and can be used for the content determination of polymer in active pharmacentical ingredient cefatrizine propylene glycol.

Progressive supranuclear palsy (PSP) with predominant cerebellar ataxia (PSP-C) is a rare phenotype of PSP. The clinical and radiological features of this disorder remain poorly characterized. Through a retrospective case series, we aim to characterize the clinical and radiological features of PSP-C. Four patients with PSP-C were identified: patients who presented with prominent cerebellar dysfunction that disappeared with the progression of the disease. Supranuclear gaze palsy occurred at a mean of 2.0 ± 2.3 years after the onset of ataxia. Mild cerebellar volume loss and midbrain atrophy were detected on brain imaging, which are supportive of a diagnosis of PSP. Videos are presented illustrating the co-existence of cerebellar signs and supranuclear gaze palsy and the disappearance of cerebellar signs with disease progression. Better recognition and the development of validated diagnostic criteria would aid in the antemortem recognition of this rare condition.

Objective To explore the indications for liver transplantation among patients with hepatolithiasis.Methods Data from 1 431 consecutive patients with hepatolithiasis who underwent surgical treatment from January 2000 to December 2006 were retrospectively collected for analysis.Surgical procedures included T-tube insertion combined with intraoperative cholangioscopic removal of intrahepatic stones,hepatectomy,cholangiojejunostomy,and liver transplantation.Results Nine hundred and sixty-one patients who had a stone located in the left or right intrahepatic duct underwent hepatectomy or T-tube insertion combined with intraoperative cholangioscopic removal of intrahepatic stones.The rate of residual stones was 7.5%(72/961).Four hundred and seventy patients who had a stone located in the bilateral intrahepatic ducts underwent surgical procedures other than liver transplantation;the rate of residual stones was 21.7%(102/470).Only 15 patients with hepatolithiasis underwent liver transplantation;they all survived.According to the degree of biliary cirrhosis,recipients were divided into 2 groups: a group with biliary decompensated cirrhosis(n=7),or group with biliary compensated cirrhosis or noncirrhosis group(n=8).There were significant differences in operative times,transfusion volumes and blood losses between 2 groups(P

Objective:To investigate the influence of collateral circulation evaluated by CT perfusion (CTP) imaging in infarction progression and clinical prognoses of patients with acute large-artery occlusion of the anterior circulation before and after thrombectomy.Methods:One hundred and ten patients with acute large-artery occlusion of the anterior circulation within 24 h of onset, admitted to our hospital from May 2018 to September 2019, were chosen in our study; all patients completed thrombectomy; their clinical data were analyzed retrospectively. Regional leptomeningeal collateral-temporally fused maximum intensity projection (rLMC-tMIP) was used to evaluate the collateral circulation based on 4D-CT angiography (4D-CTA). According to the core infarct volume in CTP imaging and the diffusion weighted imaging (DWI) results of MR within one week of surgery, the progressive infarct volume was calculated. Modified Rankin scale (mRS) was used to evaluate the prognoses of these patients 3 months after surgery.Results:(1) There were 56 patients with good collateral circulation and 54 patients with poor collateral circulation. Age ( OR=0.951, 95%CI: 0.910-0.993, P=0.023), cardiac dysfunction ( OR=0.116, 95%CI: 0.018-0.731, P=0.022), baseline fasting blood glucose ( OR=0.788, 95%CI: 0.646-0.961, P=0.019), wakefulness stroke ( OR=0.093, 95%CI: 0.023-0.380, P=0.001), and site of vascular occlusion ( OR=7.604, 95%CI: 2.650-21.821, P=0.000) were independent influencing factors for collateral circulation. (2) Scores of rLMC-tMIP ( 95%CI: -2.947- -1.474, P=0.000), volume of ischemic penumbra ( 95%CI: 0.065-0.126, P=0.000), scores of edema in the brain tissues ( 95%CI: 2.952-7.600, P=0.000), hemorrhage transformation ( 95%CI: 8.966-23.114, P=0.000), and 24 h NIHSS scores ( 95%CI: 0.606-1.248, P=0.000) were independent influencing factors for volume of progressive infarction. (3) There were 59 patients having good prognosis and 51 patients having poor prognosis. Hemorrhage transformation ( OR=0.019, 95%CI: 0.001-0.275, P=0.004) and progressive infarction volume ( OR=0.824, 95%CI: 0.756-0.897, P=0.000) were independent influencing factors for prognoses of patients with acute large-artery occlusion of the anterior circulation after thrombectomy. Conclusion:The scores of rLMC-tMIP based on 4D-CTA can well predict the infarction volume in patients with acute large-artery occlusion of the anterior circulation within 24 h of onset, which can effctively evaluate the clinical prognoses of the patients.
