Objective To investigate expression of PP2CE in human hepatocellular carcinoma(HCC)tissues and the clinical pathological significance,and test its sub-cellular localization in liver cells and HCC cells.Methods A total of 50 samples of HCC tissues and their para-carcinoma tissues were collected in Tongji Hospital(Wuhan).PP2CE mRNA and protein levels were detected in HCC tissues and their para-carcinoma tissues by qRT-PCR and immunohistochemistry method.Immunofluorescent assay was performed to test the sub-cellular localization of PP2CE in the cells.Results PP2CE mRNA and protein expression levels were significantly decreased in HCC tissues as compared with those in para-carcinoma tissues(both P＜0.05).Immunohistochemistry analysis found that PP2CE expression was associated with tumor size,differentiated degree,portal vein invasion and clinical stage(both P＜0.05).Immunofluorescent assay suggested that PP2CE was mainly located in the cytoplasm and perinuclear area.Conclusion PP2CE is reduced in HCC and may be implicated in the development and progression of HCC.

Objective To investigate the relationship of diabetic nephropathy with serum endothelin-1(ET-1) and C-reactive protein(CRP). Methods Levels of blood pressure, glucose, lipid, creatinine,ET-1,CRP and urinary albumin excretion(UAER) were measured and calculated in 86 patients with type 2 diabetes mellitus(T2DM)and 30 healthy subjects. Results Serum ET-1 and CRP were significantly higher in T2DM than in control(P<0.05，P<0.01).Serum ET-1 and CRP were increased with increment of serum creatinine and UAER(P<0.05，P<0.01). Conclusions Serum ET-1 and CRP may be involved in the development and progression of diabetic nephropathy.

Objective To determine whether concentrations of plasma homocysteine and status of folate and vitamin B12 were altered in patients with heroin dependence compared with control subjects. Methods We recruited 20 patients with heroin addiction. Twenty age-and sex-matched healthy volunteers as the control group were enrolled. Blood concentrations of homocysteine, folate and vitamin B12 were measured in a fasted status. Results Mean homocysteine level was higher in the heroindependence group than in the control group [18.3 ± 4.5 (Q1 = 14.7, Q2 = 17.6, Q3 = 19.2) vs. 8.4 ± 2.7 (Q1 = 5.9, Q2 = 8.5, Q3 = 10.5) μmol/L, P < 0.001]. Patients in heroinaddictiongroup had signi cantly lower folate levels compared with the control group [6.6 ± 2.6 (Q1=4.6, Q2=6.4, Q3=8.1) vs. 12.7 ± 2.5 (Q1 = 11.1, Q2 = 13.0, Q3 = 17.5) ng/mL, P < 0.001]. There was significant difference on plasma B12 concentrations between heroin users and controls [384.1 ± 228.8 (Q1=312.0, Q2=348.5, Q3=374.5) vs. 399.4 ± 45.1 (Q1=358.0, Q2=394.5, Q3=428.3) Pg/mL, P < 0.001]. Heroin users group demonstrated a negative correlation of homocysteine with folate , which was statistically significant in heroin users groups (r = - 0.614; P = 0.004), there was a trend towards a negative correlation of homocysteine with B12 in heroin users (r = -0.605; P = 0.005), respectively. Conclusions We conclude that patients with heroin dependence are prone to high concentration of plasma homocysteine.

Objective To discuss the clinical efficacy of point-injection with nerve growth factor (NGF) in treatment of infantile cerebral palsy.Methods According to the time order,50 cases with cerebral palsy were randomly divided into the treatment group(30 cases) and the control group (20 cases).Both groups were given the conventional treatment of Bobath mainly exercise therapy,homework therapy and the language therapy.In addition,the treatment group was given the treatment of point-injection with NGF.Gesell scale was used to evaluate all the patients before and after treatment.Results After treatment,the Gesell evaluation of the treatment group was higher than control group,and the difference was statistically significant (t =-2.096,-2.187,-2.048,-2.053,-2.225,all P ＜0.05).Conclusion On the basis of rehabilitation training,point-injection with NGF could improve intelligence,motor function and language in children with cerebral palsy,and the efficacy was obvious.

Objective: To establish a simple, stable and high success rate separation method of myocardial cells in New Zealand rabbits. Methods: Compared influence between perfusion speed of 50 r/min (8 ml/min) and 65 r/min (11 ml/min) of Langendorff perfusion device on cell separation during separation course of myocardial cells. Results: Compared with perfusion speed of 50 r/min, there was significant decrease in time to obtain cells [(33±9.10) min vs. (19.29±2.73) min], and significant increase in success rate (50% vs. 91%) and survival rate [(38.26±2.63) % vs. (85.71±2.21) %] by perfusion speed of 65 r/min, P<0.01 all. Conclusion: Perfusion speed is an important factor that affects acute separation of myocardial cells in New Zealand rabbits, and 65r/min perfusion speed may be more stable and successful to obtain single myocardial cell.

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 investigate the effect of nifedipine on brain edema and neurological function in patients with cerebral hemorrhage . Methods 72 patients with ICH from October 2013 to October 2015 in our hospital were selected, and randomly divided into experimental group and control group, 36 cases in each group.The control group used dehydration to reduce intracranial hypertension, improve cerebral circulation, promote nutritional metabolism and anti infection and other conventional treatment,and the experimental group daily intravenous infusion of 1.0 mg of nifedipine on the basis of control group, a course of ten days.The activity dependence, clinical efficacy, MESS score, ICH score, BI score, brain hematoma and brain edema volume were observed and compared between the two groups before and after treatment.Results After treatment, the activity dependence of the experimental group was significantly better than that of the control group ( P <0.05 );the clinical effective rate of the experimental group was significantly higher than that of the control group (P<0.05).BI scores of both groups were increased after treatment, MESS scores were reduced(P<0.05);The BI score of the experimental group was significantly higher than that of the control group (P<0.05),and the MESS score was significantly lower than that of the control group (P <0.05).The volume of cerebral hematoma and the volume of cerebral edema were significantly reduced after treatment in both groups (P<0.05),there was no significant difference in the volume of cerebral hematoma between two groups,there was significant difference in the volume of cerebral edema between two groups (P <0.05).Conclusion Nifedipine can effectively reduce cerebral edema in patients with cerebral hemorrhage, reduce the degree of neurological deficit, improve clinical efficacy.

Aim To investigate the effects of berberine on extracellular matrix in rat glomerular mesangial cells cultured under high glucose and its possible mechanism.Methods Six groups were divided according to the different experimental conditions:① Normal glucose group (NG);② Mannitol group (Mannitol);③ High glucose group (HG);④ SB203580 treatment group (HG+SB203580);⑤ Berberine low dosagegroup (HG+BBR 30 ?mol?L-1);⑥ Berberine high dosage group (HG+BBR 90 ?mol?L-1). The phospho-p38MAPK,phospho-cAMP response element binding protein (CREB) and fibronectin were detected by Western blot analysis. Results Berberine obviously decreased protein expression of fibronectin compared with high glucose group. Phospho-p38MAPK and phospho-CREB level was significantly lowered compared with that of high glucose group. Conclusion Berberine can inhibit extracellular matrix accumulation including fibronectin via p38MAPK signal pathway in treatment of diabetic nephropathy.

Objective The purpose of this study was to investigate the effects of short-term and high-intensity training on the biomechanics characteristic of guinea pig's Achilles tendon, and thus to propose a new training mode for quickly enhancing the ability of withstand stress and anti-injury. Method Guinea pigs were assigned to different groups according to the training intensity they would undergo, i.e. high intensity group, medium intensity training for 8-weeks group and control group. The bilateral Achilles tendons were excised after different strength training. The variety of biomechanics characteristic of different intensity and different period were observed and compared respectively. Result Compared with the control group (8.19?0.60, 30.54?5.71), both the high intensity group (group C, 11.51?2.49,35.64?5.28, group D, 14.92?2.75, 44.29?4.09) and the medium intensity group (12.37?2.15, 36.36?4.94) show significant differences (P
