Objective To observe the safety and efficacy of the SLIPA mask airway in the cesarean section operation under general anesthesia.Methods Fifty single birth pregnant women who underwent cesarean operation under general anesthesia were randomized into 2 groups.SLIPA mask group(group S,25 cases)and endotracheal intubation(ETT)group(group T,25 cases).Mean arterial pressure(MAP),heart rate(HR),partial pressure of carbon dioxide in end expired gas(P_(ET)CO_2),peak airway pressure(Paw)were measured before induction of anesthesia,just before intubation,2min after intubation,just before extubation,2 min after extubation.Bucking,style,reflow,vomiting,aspiration were observed at inmbation or SLIPA mask airway insertion,before and after extubation and intraoperative.Umbilical arteries and veins blood were collected at delivery for the blood gas analysis.All delivery times,operation time and Apgar scores at 1,5 min were recorded.Results The successful rate ofthe first time intubation was 100% in group S,there was 2 cases by the second time intubation in group T.There Was 3 cases with gently air leak,but no influence on respiratory management.After intubation and extubation,MAP and HR increased significantly in group T (P<0.05),while group S had no significant change.There was no occurrence of bucking,style,reflow,vomiting,aspiration intmoperative,but 17 cages occurred at extubation in group T.The incidence and degree of sore throat in group T(10 cases after 2 hours and 6 cases after 24 hours) were significantly higher than those in group S(P<0.05).The Apgar scores at 1,5 min and delivery times were not significant between the two groups(P>0.05).Conclusion There is less adverse effects of SLIPA mask airway than ETT under general anesthesia in the cesarean section operation,SLIPA mask airway is safe and efficacious.

The liver is an important organ of the body,with an extraordinary capacity for responding to physical or chemical injuries by regenerating. The mechanisms behind liver regeneration are very complicated as hundreds of substances are involved.However,most of them are not liver-specific,such as HGF,EGF etc. We recently isolated a pure protein with hepatic stimulatory activity from the extract of a weanling calf liver and named its hepatopoietin Cn (HPPCn).This paper,with reference to our own work, mainly reviews the development and bioactivity about hepatic stimulator substance(HSS),augmenter of liver regeneration(ALR),hepassocin(HPS) and HPPCn,which are liver-specific biologically active peptides.

Objective To observe the effect of electroacupuncture on improvement of learning and memory ability and the expression of connective tissue growth factor(CTGF)mRNA and protein in hippocampus in diabetic rats with cognitive impairment.Methods The rat diabetes model was induced by injecting streptozotocin(20 g/L),and then the rats were randomly divided into three groups:electro-acupuncture group(EA),diabetes-mellitus-untreated group(DM)and control group(CN).After four weeks of electroacupuncture treatment,blood glucose level was determined and the effect of electroacupuncture on learning and memory was examined with the device of Morris water maze.RT-PCR was used to detect CTGF mRNA level,and immunohistochemistry was used to detect CTGF protein expression.Results Blood glucose level and the latency period in DM group were increased compared with those in EA and CN groups(P

Achalasia is a rare primary oesophageal motility disorder that presents as a functional obstruction at the oesophago-gastric junction. The prevalence of achalasia in Down syndrome is much higher, which implies a unique association between these two uncommon conditions. Although the exact aetiology of achalasia is unknown, studies have proposed that its pathogenesis is related to autoimmune, infectious or genetic factors, leading to the intrinsic loss of inhibitory myenteric neurons in both the oesophagus and lower oesophageal sphincter. We herein report the case of a 16-month-old girl with Down syndrome and achalasia who was initially treated for gastro-oesophageal reflux disease. The diagnosis of achalasia was made only when her condition deteriorated, with subsequent failure to thrive, and upon further investigations, including barium swallow study and upper endoscopy. We also review the various mechanisms postulated in the development of achalasia in Down syndrome, as well as the various treatment modalities available for this rare disorder.

Objective To investigate the effects of fluvastatin on the tubulointerstitium damage in progressive diabetic kidney disease. Methods A rat model of type 2 diabetic nephropathy (DN) was developed successfully by combination of dietary induced insulin resistance and low dose STZ induced hyperglycemia after unilateral nephrectomy. Female SD rats were randomly divided into three groups: control rats, type 2 diabetic rats and type 2 diabetic rats treated with fluvastatin (2mg/kg/d). After 6 weeks, blood glucose, serum insulin, serum triglyceride and cholesterol, serum creatinine, and urinary protein were measured respectively. The protein expressions of c Jun and tansforming growth factor (TGF) ? 1 were studied by immunohistochemistry. TGF ? 1 gene expression was studied with a RT PCR technique. Results Fluvastatin at lower doses, which did not influence blood glucose and blood lipid level, significantly inhibited expression of c Jun protein(0 2536?0 0180 vs 0 5855?0 0314, P

BACKGROUND:Currently, bone marrow mesenchymal stem cel s can differentiate into nerve cel s via many approaches. Different methods for inducing bone marrow mesenchymal stem cel s differentiating into nerve cel s have different ratios. OBJECTIVE:To investigate the difference between chemical method and co-culture method to induce the differentiation of rat bone marrow mesenchymal stem cel s into nerve cel s. METHODS:Rat bone marrow mesenchymal stem cel s were isolated and purified using whole bone marrow culture method, and then randomly divided into two groups:chemical group,β-mercaptoethanol was added;co-culture group, co-cultured in a Transwel chamber. RESULTS AND CONCLUSION:Visible protrusions from induced cel s showed radiation growth at 1 week of induced culture, and neuron-specific enolase staining was positive at 2 weeks of culture. Star-like structure of nerve cel s was visible in the co-culture group within 4-5 days of culture, and then more protrusions formed. Meanwhile, the positive rate of neuron-specific enolase was (70.82±2.46)%. After 6-7 days of culture, neuron-like cel s formed and were interconnected in the chemical group;while, the positive rate of neuron-specific enolase was (52.37±1.83)%. These findings suggest that cel microenvironment plays a leading role in the differentiation of bone marrow mesenchymal stem cel s into nerve cel s, and chemical induction method is inferior to the co-culture method.
