2.Predictors at nadir of severity on patients with Guillain-Barr? syndrome
Chinese Journal of Neurology 2001;0(02):-
Objective To explore the factors relating to the severity of Guillain-Barr? syndrome (GBS) (i.e. of being the mild form or in need of mechanical ventilation), and to find the predictors in early clinical presentations and laboratory investigations as to guiding the early management of GBS. Methods All 123 cases of patients with GBS admitted to Xuanwu Hospital from 1996-2002 were collected, and divided into two groups based on the international criteria for different severity of GBS. Mildly affected patients (i.e. able to walk unaided during the whole course or the Medical Research Council [MRC] muscle power grading scale≥4 in both lower limbs at nadir) and ventilated patients (i.e. in need of mechanical ventilation) were divided in this study. Characteristics of each group in early clinical presentations and laboratory investigations were analyzed in univariate conditional Logistic model in order to find out the predictors. Results In all 123 patients studied, 32 were having mild GBS; 29 severe GBS (i.e. in need of mechanical ventilation during the course). Men (P=0.047) and patients without bulbar dysfunction (P=0.002) were more likely to become mild GBS. The possibility of being mild form was 3.33∶1 between man and woman, 1∶20.17 between those with and without bulbar dysfunction. Patients with bulbar dysfunction (P

Objective To study the case of 76 patients with choledochoduodenal fistula ( CDF) ,and summarize the experience of mak-ing diagnosis and treatment. Methods From January 1999 to June 2012,76 patients with CDF were treated in our department and then was confirmed by endoscopic retrograde cholangiography ( ERCP) . All patients were classified based on the location of duodenal papilla in rela-tion to the orificium fistulae of CDF. Different therapies were used to certain CDF depending on the diameter of the orificium fistulae of CDF. Of the 76 CDF patients,70 patients (92%) required surgery. Results The fistula of 76 CDF patients have three types,and the formation of this classification was based on the position between the duodenal papilla and the orificium fistulae of CDF. Different therapies referred to cer-tain diameter of CDF,70 patients required surgery and 6 acquired pharmacotherapy. Of the 70 patients needing surgical intervention,clinical outcomes were excellent in 66 patients. Follow-up of these patients for 6 months to 10 years showed they did not suffer from further cholangi-tis. Conclusion The past history of biliary disease,upper abdominal pain,fever,and jaundice may lead to the disease of CDF. ERCP was the primary method for diagnosing this disease,and operative therapy was the primary treatment for most CDF patients.

Objective To investigate the possible regulating effect of integrin-linked kinase (ILK) towards matrix metalloproteinase-9/tissue inhibitor of metalloproteinase-1 (MMP-9/TIMP-1) ratio in the process of transforming growth factor-β1 (TGF-β1)-induced epithelial-mesenchymal transition (EMT) in human kidney proximal tubular epithelial (HK-2) cells.Methods HK-2 cells were cultured and stimulated with 10 ng/ml TGF-β1.Specific ILK-small interfering RNA (ILK-siRNA) was used to inhibit ILK expression.The characteristic epithelial marker (E-cadherin) and mesenchymal marker (α-SMA) of EMT were examined by Real-time reverse transcription polymerase chain reaction (real-time RT-PCR) and Western blot.The expressions of ILK,MMP-9,and TIMP-1 were also examined,to determine the regulating effect of ILK towards MMP-9/TIMP-1 ratio.Results In the HK-2 cells cultured with TGF-β1,the expression of E-cadherin decreased,and α-SMA expression increased;overexpression of ILK and an abnormal changing of MMP-9/TIMP-1 ratio were observed.ILK inhibition by ILK-siRNA could adjust MMP-9/TIMP-1 ratio to near normal.Meanwhile,the overexpressed ILK and α-SMA were decreased.Conclusions Our data indicates that ILK-siRNA successfully inhibits ILK expression,which regulates the MMP-9/TIMP-1 ratio in HK-2 cells.The inhibition of ILK expression suppresses TGF-β1-induced EMT partially.

BACKGROUND: Recent researches demonstrate that transplantation of bone marrow stem cells in the area of myocardial infarction can directionally differentiate into myocardial cells having normal physiological function and can promote newborn vascularization so as to repair infarction myocardium and improve injured cardiac function.OBJECTIVE: To observe short-term clinical effect of autologous bone marrow stem cell transplantation (ABMSCT) in percutaneous coronary artery on the treatment of acute myocardial infarction.DESIGN: Self-control study.SETTING: Department of Cardiology, Xiangtan Central Hospital.PARTICIPANTS: A total of 27 patients with acute myocardial infarction, including 16 males and 11 females, were selected from Department of Cardiology, Xiangtan Central Hospital from June 2004 to December 2006. Their ages coronary artery was finished after onset emergently; in addition, blood flow of infraction related vessels recovered to grade TIMI3. All patients provided the confirmed consent.METHODS: Operative procedure: All patients were performed with emergently interventional therapy of coronary artery after onset of acute myocardial infarction. One week later, percutaneous cavity tube technique was used to establish infarction related arterial pathway, and guiding filament was used to send micro-perfusion tube into stents. And then,separated bone marrow stem cell suspension was poured through central cavity of micro-tube into the distal end of infarction vessels. Operative evaluation: Dynamic electrocardiogram was evaluated for 24 hours before and after transplantation; in addition, left ventricular ejection fraction and myocardial perfusion defect scores were detected before and at 6 and 12 months after transplantation; otherwise, recovery state and complication were observed in follow up at 6 and 12 months after operation.defect scores: At 6 and 12 months after operation, left ventricular ejection fraction was higher than that before transplantation, and there was significant difference before and after transplantation (P<0.05). While, myocardial perfusion defect scores were lower than those before transplantation, and there was significant difference before and arrhythmia were not found out, cardiac arrhythmia was not increased, and cardiac arrhythmia combining with malignancy not have any complications and in-stent constriction after operation.
