ABSTRACT
OBJECTIVE:To systematically evaluate therapeutic efficacy and safety of recombinant mutant human tumor necrosis factor(rmhTNF)versus pleural perfusion of cisplatin in the treatment of malignant pleural effusions,and to provide evidence-based reference in clinic. METHODS:Retrieved from PubMed,Cochrane Library,Web of Science,CJFD,Wanfang database,VIP and CBM,RCTs about rmhTNF(trial group)vs. cisplatin(control group)in the treatment of malignant pleural effusions were included. Meta-analysis was conducted by using Rev Man 5.3 statistical software after quality evaluation and data extraction with Cochrane system evaluator manual 5.3.0. RESULTS:A total of 7 RCTs were included,involving 478 patients. Meta-analysis showed that clinical total response rate of trial group [RR=1.43,95%CI(1.27,1.62),P<0.001] was significantly higher than that of control group,with statistical significance. There was no statistical significance in the incidence of gastrointestinal reaction[RR=1.15,95%CI(0.73,1.80),P=0.55],chest pain[RR=1.12,95%CI(0.73,1.73),P=0.60],fever[RR=0.62,95%CI(0.35,1.08),P=0.09] and myelosuppression[OR=0.94,95%CI(0.57,1.54),P=0.79] between trial group and control group. CONCLUSIONS:Pleural perfusion of rmhTNF is significantly better than cisplatin in the treatment of malignant pleural effusions. The incidences of gastrointestinal reaction,chest pain,fever and myelosuppression induced by rmhTNF were similar to those induced by cisplatin.
ABSTRACT
Objective To investigate the association between the nutritional status and related factors in patients with Parkinson's disease (PD).Methods Seventy-two patients with PD (PD group) and 71 age-and sex-matched healthy controls (control group) were enrolled in this study from September 2014 to November 2017 at the First Affiliated Hospital of Sun Yat-sen University.Their serum nutritional indices,including serum albumin,prealbumin,transferrin,free fatty acid and retinol conjugated protein,were collected.The PD participants were interviewed and assessed using motor and non-motor scales,including Hoehn and Yahr stage,Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS),Non-Motor Symptoms Questionnaire for Parkinson's Disease (NMSS),Mini-Mental State Examination (MMSE),Unified Dyskinesia Rating Scale (UDysRS) and 39-item Parkinson's Disease Questionnaire (PDQ-39).Their medication dosage was indicated by daily levodopa equivalent doses (LEDD).Body mass index (BMI) was used to determine their nutritional status,with abnormal nutritional status defined as BMI lower than 20 kg/m2.Results Levels of serum albumin (41.60 (40.28,43.98) g/L vs 44.00 (42.30,46.20) g/L,Z=4.500,P＜0.01),transferrin ((2.32±0.34) g/L vs (2.51±0.34) g/L,t=-3.305,P=0.001),and free fatty acid (418.00 (289.75,637.25) μmol/L vs 547.00 (386.00,699.00) μmol/L,Z=2.079,P=0.038) of the PD group were significantly lower than those of the control group.There was a significant negative correlation between serum albumin and MDS-UPDRS-Ⅱ score (r=-0.254,P=0.031),MDS-UPDRS-Ⅳ score (r=-0.256,P=0.030),years of dyskinesia (r=-0.240,P=0.043),years of motor fluctuation (r=-0.304,P=0.009) and LEDDs (r=-0.321,P=0.006).Disease duration was negatively correlated with serum albumin (r=-0.285,P=0.015) and transferrin (r=-0.275,P=0.019),and age (r=-0.252,P=0.032) was negatively correlated with prealbumin.The forward binary Logistic regression model indicated that abnormal nutritional status was closely associated with rigidity (OR=1.171,95％CI 1.013-1.354,P=0.032),akinesia (OR=1.070,95％CI 1.000-1.144,P=0.048),UDysRS score (OR=1.051,95％CI 1.004-1.099,P=0.032),MDS-UPDRS-Ⅳ score (OR=1.177,95％CI 1.018-1.360,P=0.027) and MMSE score (OR=0.821,95％CI 0.678-0.994,P=0.043),but not correlated with tremor and axial symptoms.Compared with PD patients with abnormal nutritional status,PD patients with normal nutritional status had higher MMSE scores (28.00 (27.00,29.00) vs 28.00 (25.00,28.00),Z=-2.060,P=0.039),lower rigidity (9.60±3.83 vs 12.00±4.29,t=-2.264,P=0.027),akinesia (19.98 ± 8.00 vs 24.42:±:8.06,t=-2.071,P=0.042) and MDS-UPDRS-Ⅳ scores (8.00 (5.00,11.00) vs 10.00 (9.00,13.00),Z=2.642,P=0.008).Conclusions PD patients tend to have a lower serum nutritional indices.PD patients with lower levels of serum nutritional indices are characterized by more severe motor complication,longer disease duration,older age and higher LEDD.PD patients with abnormal nutritional status have worse cognition and more severe motor symptoms (rigidity,akinesia and motor complication).
ABSTRACT
The pathogenesis of icteric hepatitis is that pathogenic dampness blocks the middle energizer or blood stasis blocks the bile duct,so that the bile is not excreted normally and moves to the skin surface,which makes the skin yellow.Traditior al Chinese medicine (TCM) has unique advantages in the prevention and treatment of icteric hepatitis.This article systematically introduces the etiology and pathogenesis of icteric hepatitis and the TCM syndrome differentiation therapy for icteric hepatitis,in order to provide a reference for the clinical treatment of icteric hepatitis and the improvement in its prognosis.

ABSTRACT
Objectives:To examine the effect of chloride blocker (NPPB and tamoxifen)on volume sensitive chloride channels in mouse cardiac ventricular myocytes. Methods:Isolated mouse cardiac ventricular myocytes were subjected to whole cell patch clamp to record the hypotonicity activated chloride currents. Results:When the myocytes were exposed to hypotonic solution, an obvious whole cell currents were activated. The currents were inhibited by extracellular NPPB reversibly and significantly. The specific blocker for volume sensitive chloride channel , tamoxifen (50 ?mol/L), could apparently block the activity of this channel in a voltage dependent manner. Conclusions:Mouse cardiac ventricular myocytes process volume sensitive chloride channel which is sensitive to NPPB and tamoxifen.
ABSTRACT
Objective The effects of free fatty acid on leptin receptor in rat islet cells were investigated. Methods Islet cells of newborn sprague Dawley rats were incubated with palmitate acid (0 25mmol/L) or oleic acid (0 125mmol/L) for 12 hours, 24 hours and 36 hours respectively. Western blotting was used to assess the protein content of leptin receptor in rat islet cells. The RNA expression level of leptin receptor was assayed by RT PCR. Tyrosine phospholation of leptin receptor was determined by method of immuno precipitation. Results The protein content of leptin receptor in rat islet cells was significantly decreased after being incubated with free fatty acids for 24 and 36 hours compared with the control ( P
ABSTRACT
Objective:To investigate the effect of free fatty acid on leptin receptor in rats.Methods:High plasma free fatty acid rat model was created by intravenous injection of free fatty acid. Western blot was used to assess the protein level of leptin-receptor in rat liver, muscle and pancreas tissues. The RNA expression level of leptin-receptor was examined by RT-PCR .The tyrosine phosphorylation of leptin-receptor was examined by immuno-precipitation. Results:The protein and RNA levels of leptin-receptor in liver,muscle and pancreas tissues of high plasma free fatty acid rats were similar to those of normal group(P>0.05).But the tyrosine phosphorylation of leptin-receptor significantly downregulated in liver and muscle tissues as compared with control group(P<0.05). Conclusions:High plasma free fatty acid may affect the tyrosine phosphorylation of leptin-receptor in rat liver and muscle.
