Objective To introduce the clinical significance and pathophysiologic aspects of the circulatory and cardiac complications in terminal stage cirrhosis.Methods Recently relevant literatures were reviewed and summarized.Results Haemodynamic changes in cirrhosis arose on the basis of combined humoral and nervous dysregulation,with abnormalities in cardiovascular regulation,volume distribution and cardiac performance.Conclusion Comprehending the mechanisms of cardiovascular complications will contribute a lot for the treatment of terminal stage cirrhosis.

Objective:To explore the early warning value of carbapenem-resistant Klebsiella pneumoniae (CRKP) positivity in liver transplantation recipients with rectal swabs, examine the risk factors of CRKP bloodstream infection and provide the relevant treatments.Methods:From June 2018 to December 2019 in Organ Transplantation Research Institute Affiliated Tongji Hospital Tongji Medical College Huazhong University of Science & Technology, 148 cases of liver transplantation recipients with positive CRKP rectal swabbing were recruited. Clinical data were retrospectively analyzed. And the risk factors of CRKP bloodstream infections were examined for intervention and non-intervention groups to observe the effect of interventions of CRKP bloodstream infections.Results:Among them, 23 cases (15.5%) were positive for CRKP and 5 cases (21.7%) were infected with CRKP bloodstream. Rectal swab culture was negative in 125 cases and no bloodstream infection occurred. Long-term use of broad-spectrum antimicrobial agents, severe basic diseases (severe hepatitis), postoperative delayed graft liver function recovery, acute renal failure requiring renal replacement therapy (RRT) and postoperative anti-thymocyte globulin (ATG) induction were risk factors. In intervention group, there were 2 cases (11.1%) of 18 patients with positive CRKP in rectal swab culture in late stage. Among 5 CRKP-positive recipients without intervention, 3 cases (60%) developed later CRKP bloodstream infection. The incidence of bloodstream infection was significantly lower in intervention group than that in non-intervention group ( P<0.05). Conclusions:Rectal swab culture for liver transplantation recipients provides early warning for CRKP bloodstream infection. Interventions for CRKP positive high-risk recipients with rectal swab culture may reduce the occurrence of CRKP bloodstream infection and lower the risk of CRKP bloodstream infection in liver transplantation recipients.

Objective To investigate the mechanism of recombinant human growth hormone(rhGH) in articular cartilage defect repair in vivo.Methods The cylindrical,full-thick articular cartilage defects,(3.5 mm) in diameter,were made in the knee joints of 25 rabbits.rhGH of 0.1 U/kg was injected into the right knee joints 3 times a week for 4 weeks and equal volume of physiological saline to the left knee joints as control.The animals were killed respectively in 4,6,8,12,24 weeks,and the macroscopic,histologic and ultrastractural examinations were performed.Results The repairing process in experimental group was faster and better than that in the control.In the experimental groups,the defect was filled on week 4,the regenerated cartilage mainly in the shallow region and fibrous tissue in the deep region;on week 24,the regenerated tissue was morphologically close to the neighbour normal cartilage,hard to differentiate by macroscopy;Light microscopy showed the defect recovered to normal cartilage structure and the electron microscopy showed a large quantity of mature cartilage cells.In the control groups,the defect was of shallow introcession,mainly of fibrous tissue.The histological examination showed the significant difference between experimental and control groups(P

Objective To describe the clinical features of convulsive status epileptieus (CSE) in our hospital and to provide a basis for future CSE prevention and treatment. Methods Patients with CSE hospitalized from January 1996 to October 2007 were prospectively observed. Logistic regression was used to identify predictors of prognosis. Results All 220 eases of CSE were prospeetively analyzed, a hundred and two patients(46.4%) originated from rural areas. The primary cause of CSE was central nervous system(CNS)infectian (72cases, 32.7%), followed by discontinuation or reduction of antiepileptie drugs (AEDs, 35 cases,15.5%). The median duration of CSE was 5 hours and median duration of seizures before treatment was 2 hours; both were longer in rural patients (7.0 and3.5 hours respectively) than in urban patients (3.0 and 2.0 hours, Z=-3.433,-1.558,both P<0.05). The fatality rate by the time of discharge was 15.9%. Logistic regression analysis showed that the duration of CSE (χ2=20.941), a history of epilepsy (χ2=4.910), and respiratory depression (χ2=16.086) were independent predictors of CSE prognosis (allP<0.05) . Comparisons between these data of USA and Europe were made. Conclusions CSE occurs mostly in rural population and epilepsy patients. CNS infection and withdrawal or reduction of AEDs in patients with epilepsy were important triggers of CSE. Antiepileptic therapy for status epilepticus in China falls behind that in the European countries.

Objective To explore the clinical and pathological characters of Xp1 1.2 translocation renal cell carcinoma.Method We screened patients of renal cell carcinoma of PUMCH between Jan.2011 and Dec.2015,6 patients with Xp11.2 translocation renal cell carcinoma were found.There were 2 males and 4 females,with average age of 39 (ranging from 16 to 73 years old).Diameter of tumor ranged from 1.9cm to 19.0cm,and 9.6cra in average.Among which,3 cases were detected by routine physical examination,1 by severe anemia (Hb 66g/L),1 by gross hematuria,and 1 by flank discomfort.Before treatment,2 cases had local metastasis (local lymph node,renal pelvis invasion),1 had distant metastasis (pulmonary metastasis).CT examination showed that the tumors had soft tissue density / low density,with significant enhancment or uneven enhancement in enhanced scanning,and were all considered malignancy.6 patients were all treated with surgeries,of which 5 patients received radical nephrectomy,1 patient received nephron sparing surgery.Result Pathologically,most clear cells arranged in a papillary,nest like structure,with psaamoma bodies in them.Immunohistochemical examination showed that all patients were positive for TFE3.AE1/AE3,RCC,Vimentin,CD10,EMA,P504 were positive in different degree.According to pathological result,all 6 patients were proved to be Xp1 1.2 translocation renal cell carcinoma.After surgery,2 patients received immunotherapy,2 received targeted drug therapy,and 1 received local radiotherapy.The follow-up duration ranged from 9 to 56 months (average 37 months).Among which,1 patient died from tumor recurrence and multiple metastasis 22 months after surgery,1 had pulmonary metastasis 12 months after surgery,and the tumor had no significant progress after receiving targeted drug therapy.All the other patients survive without tumor recurrence.Conclusions Xp1 1.2 translocation renal cell carcinoma predominantly occurs in children and adults younger than 40 years.Arterial phase enhancement is slightly lower for Xp1 1.2 translocation renal cell carcinoma in CT scan than that of renal clear cell carcinoma.Histological features and immunohistochemical staining of TFE3 positive expression are important means of diagnosis of this disease.If necessary,gene detection could be done to make better diagnose.Surgery is preferred treatment option.Metastatic leads to poor prognosis,and need to be supplemented by targeted drug therapy.
