The end stage of chronic renal diseases is characterized by glomerular sclerosis and interstitial fibrosis. Studies have revealed that effective amelioration of renal fibrosis can significantly delay the progression of chronic renal diseases. Peroxisome proliferator activated receptors (PPARs) are ligand-activated nuclear transcriptional factors of the nuclear hormone receptor superfamily, and PPAR-γ is one of the phenotypes of PPARs. The effect of PPAR-γ on inhibiting renal fibrosis has become a hot spot. In this article the research advances of PPAR-γ in amelioration of renal fibrosis are reviewed.

AIM: To observe the effect the combination of hydrobromidum (654 2) and salviae miltiorrhizae on diabetic peripheral neuropathy (DPN). METHODS: sixty two cases of DPN were given the normal treatment of diabetes. Based on the treatment, they were divided into three groups at random. The first group (n=24) was given the combinction 654 2 and salviae miltiorrhizae, the second group (n=20) was given 654 2 alone, and the third group (n=18) was given salviae miltiorrhizae alone. RESULTS: The effertive rates in the first, the second and the third group were 79.2 %, 45% and 27.8 % (P

The incidence of severe viral pneumonia increased year on year,cardiac dysfunction is one of the commonest complications in severe pneumonia.But it is still controversial whether or not the severe pneumonia is associated with heart failure.This article focuses on the mechanisms and the treatment of severe pneumonia complicated with cardiac dysfunction.

Using floating microelectrode, the effects of furosemide on action potential and contractile force were studied in isolated toad atrial myocardium. Furosemide increased the force of contraction of toad right atrial myocardium, amplitude and dV/dtmax of action potential, and prolonged action potential duration at 50% repolari-zation (APD50), but the APD25, APD90 and sinus cycle length ( SCL) were not influenced. The positive intropic effect of furosemide could be blocked by Verapamil. These results indicated that furosemide could promote the Ca++ inward current.

Objective To evaluate the clinical efficacy of dexmedetomidine given intranasally for day surgery recovery period.Methods 60 pediatric patients who were treated for elective day surgery were selected as study objects,and they were randomly divided into control group and observation group according to the digital table,30 cases in each group.During operation, after induction of 8% sevoflurane inhalation at 8 L/min,3% of sevoflurane was maintained at 1 L/min.After intubation,0.5 g dexmedetomidine was given intranasally in the observation group, 0.9% NaCl saline was given to the control group.Mean arterial pressure (MAP),heart rate (HR),oxygen saturation (SpO2) were observed at different time points.The recovery time, number of cases of agitation, Aono agitation scale, children anesthesia delirium PAED score and the incidence of adverse reactions were observed in the two groups.Results As the time passed by, the MAP,HR,SpO2 in the two groups stabilized, except HR of the observation group at T0 time was higher than the control group[(92.92±3.22)beats/min vs.(89.32±3.22) beats/min], the difference was statistically significant(t=2.34,P<0.05).The children of the observation group recovered more slowly than the control group[(20.55±0.97)min vs.(18.62±1.03)min,t=2.17,P<0.05)],the number of cases of agitation, Aono restless score, anesthesia delirium PAED scores were lower than children in the control group (t=5.38,3.72,2.56,all P>0.05).The overall incidence of adverse reactions was similar in the two groups, there was no statistically significant difference (13.33% vs.10.00%,x2=0.12,P>0.05).Conclusion Dexmedetomidine given intranasally for the children underwent day surgery can significantly improve the quality of children awakeness, reduce the incidence of postoperative delirium, and without significant side effects.

Through introducing the current situation of systemic pediatric emergency protocol,including five-level triage system,pediatric critical rescue protocol,pediatric trauma life support,emergency observation and guidelines for the pediatric intrahospital transport,we reviewed the issues of pediatric emergency to put forward recommendations.

Objective To investigate the effects of rehabilitation therapy after revision of the totally replaced hip. Methods Forty one patients with various revision operations on the totally replaced hip were administered with rehabilitation exercises protocols different from those with the first time total hip replacement(THR), and evaluated with Harris hip function score before and after treatment. Results According to the rehabilitation therapy and exercise program that we planned meticulously, the hip function recovered well, and the total Harris hip function score of pain, function, ROM and deformity improved significantly from (39.71?6.68) to (76.37?11.23)( P

Objective To explore the efficacy and safety of clinical application of bronchofibroscope (BFS) in PICU. Methods Seventy-nine critically ill children in our PICU were operated with BFS in 89 cases and the etiology of these children was analyzed. The blood-gas analysis and oxygenation index both before and after the treatment had been compared, and syndrome was observed as well. For 40 cases in which critically ill children received bronchoalveolar lavage in addition to mechanical ventilation, and the index of respiratory mechanics was analyzed. Analysis and summary had been performed on the culture results of bronchoalveolar lavage fluid in 74 cases. Results The primary disease in these cases was mainly respiratory diseases (64/79). There was no major change in oxygenation index and blood pH ( P ＞0. 05 ) before and after operation with BFS. No severe syndrome,such as sudden cardiac arrest and pneumothorax, was recorded. However,transient decrease in SpO2 was most frequently observed in minor syndromes (15/79). The children treated with mechanical ventilation were recorded with significant decrease in air way resistance ( P ＜ 0. 05 ) after bronchoalveolar lavage. However,dynamic compliance and work of breathing only changed slightly (P ＞0. 05 ). The culture positive rate of bronchoalveolar lavage fluid was 29. 1% (23/79) ,mainly gram-negative bacteria, which coincided with disease spectrum of PICU. Conclusion The application of BFS in PICU can improve salve and tracheobronchial management for critically ill children. The diagnosis and treatment is safe and reliable by strictly grasping the examination indication by BFS under the custody of PICU.

Objective To discuss the effectiveness of rehabilitation training after arthroscopic rotator cuff repair.Methods Seventy-four cases of arthroscopic rotator cuff repair were studied.They were randomly divided into a treatment group and a control group.Both groups received shoulder passive motion training after the operation.The treatment group also received 3-phase shoulder exercises for rehabilitation.changes in American shoulder & elbow surgeons' scores (ASES scores),University of California at Los Angeles shoulder scoring system scores (UCLASS),and visual analogue scale (VAS) scores were assessed pre-operation,and 6 months and 1,2 and 3 years later.Results There was no difference between the groups pre-operation.After the operation,significant improvements in all the outcome measurements were observed in the treatment group.Significant improvement in VAS scores was observed only in the treatment group.Shoulder pain,mobility,range of active forward flexion,strength of forward flexion and patient satisfaction all improved significantly more in the treatment group than in the control group.Conclusions Early and systematic rehabilitation training is an effective way to improve the function of the shoulder joint after arthroscopic rotator cuff repair.
