Phospholipase A2(PLA2) activity in rat serum and honiogenate of liver and lungs was determined by the method of titrating.It was found that serum PLAi activity of adrenalectornized rats(ADX) was 75.13 + 7.94 U, which was significantly different from that of control rats (58.88 ?15.33U).When ADX were injected with hydrocortisone(5 mg/100g tody weight) and decapitated 2h later, the serum FLA2 activity was 55.09?8.63U, which did not differ significantly from that of controls.However, the PLAi activity in the homogenate of lungs and.liver had no significant change.These results show that glucocorticoids exerted tonic inhibition of rat serum PLA2.

There was no significant increase of serum glucocorticoid in partial adrenalectomized rats after scalding, whereas glucocorticoid receptor in hepatic cytosol of those rats tended to increase. And 6 h after scalding, the difference between scalded and controlled rats was highly significant. Hepatic glucocorticoid receptor mRNA was also determined by the method of dot blot. It was found that hepatic gluco corticoid receptor mRNA of partial adrenalectomized rats was increased 6h after scalding. Those results suggest that the decrease of hepatic cytosol glucocorticoid receptor in scalded intact rats was dependent on the rise of serum glucocorticoid.

Previous work in our laboratory showed that, after scalding, there was not only a decrease of rat liver cytosol [3H]-Dexamethasone specific binding sites but also an increase of apparent dissociation constant of [3H]-Dex and a change of sedimentation coefficient of glucocorticoid receptor (GCR).The present study was carried out using photoaffinity labeling of GCR in rat liver cytosol.It was found that there was no significant difference between molecular weights of . GCR in normal and scalded rats determined by SDS-polyacrylamide gel electrophoresis. Our result suggests that change of sedimentation coefficient is not due to alteration of molecular weight of GCR binding subunit.

Objective To conduct a meta-analysis of the curative effect and safety of the drug-coated balloon (DCB) and uncoated balloon (UCB) in treating femoropopliteal artery ischemic disease in order to provide more credible conclusion to guide clinical practice.Methods By retrieving relevant documents contained in Medline,EMbase,Cochrane library,EBSCO,Springer Link,Scopus,Web and other data pools,the research articles of clinical trials that met the inclusion and exclusion criteria were collected.According to the risk assessment standard of Cochrane collaboration network,the academic qualities of included articles were evaluated,the relevant data were extracted,then,the meta-analysis was conducted with RevMan5.3 software.Results A total of 8 papers were collected,which were originated from 6 clinical trials (from 2008 to 2015) and included 1188 patients in total.DCB group had 722 patients,and UCB group had 466 patients.Meta analysis showed that the target lesion revascularization (TLR) rates at 6,12 and 24 months after angioplasty in DCB group were significantly lower than those in UCB group.The late lumen loss (LLL) amount and re-stenosis rate at 6 month after angioplasty in DCB group were lower than those in UCB group.No statistically significant differences in amputation rate and mortality at 6,12 and 24 months after angioplasty existed between the two groups.Conclusion In treating femoropopliteal artery ischemic disease,the use of DCB is superior to the use of UCB in aspects of TLR rate,LLL amount and re-stenosis rate,besides,no significant difference in safety exists between DCB and UCB.Therefore,priority should be given to the use of DCB when the patient's economic conditions permit.

Objective To investigate women's psychological o utcome and its effect factors before and after hysterectomy. Methods In the clinical prospective study, 83 women were investigated for the ir psychiatric status with BDI, HAMD and SCL-90 questionnaires at the time of a dmission and 3 months after hysterectomy. Results The posto perative scales of BDI, HAMD, and SCL-90 were significantly lower than the preo perative ones. The morbidity of depression was decreased from 33.7% to 10.1%. Th e changes of SCL-90 were varied among different age groups. Before hysterectomy , HAMD scales were related negatively to women's educational level, but positiv ely to chief complaints. However, after hysterectomy, HAMD scales were related p ositively to parity, having other physical diseases, but negatively related to p atient's age. Conclusion Hysterectomy is beneficial to wom en's psychiatric and somatic health. Depression occurring before and after hyst erectomy is seen more often in women younger, having more parity, less-educate d, complaining of dysmenorrhea and/or menorrhagia and having other diseases.

To report a case of fructose-1, 6-bisphosphatase deficiency child with delayed diagnosis for seven years, and review the literature. A 13-year-old boy presented with recurrent episodes of hypoglycemia after infection since 6 years old, he also had convulsion and short stature. The laboratory finding revealed ketotic hypoglycemia, lactic acidosis, transient elevated ALT and UA. The genetic analysis showed compound heterozygous mutations of c. 960-961insG and c. 355G> A in FBP1 gene. Among eighteen patients reported in China, 88.9% had convulsion, 16.7% had growth retardation, the average delayed diagnosis spent 2.8 years, which could result in permanent brain damage and high death risk. The most common mutation was c. 960-961insG, followed by c. 355G>A and c. 490G>A, these mutations maybe hot spot sites of FBPl gene in China.

BACKGROUND:Generaly, the stent surface modification, especialy seeding cels, may accelerate or cause stent endothelium, and cause restenosis for prevention of in-stent thrombosis.
OBJECTIVE: To develop the optimal conditions for vascular stents coated with bone marrow mesenchymal stem cels.
METHODS: Cerebrovascular stent was co-cultured with passage 3 bone marrow mesenchymal stem cels from rats at 1×106, 1×107, 1×108, and 1×109/L. Cels on the stents were examined with transmission electron
microscopy after 48 hours. A total of 160 male Sprague-Dawley rats were enroled, among which, 20 rats were as normal control group, and the remaining 140 were used for producing models of ischemic stroke that were
randomly sub-divided into seven groups at 8 weeks after modeling: stainless steel stent implanted group, polymer stent group, and different concentrations of cellstent composite groups. After 8 weeks of implantation, the
expression of vascular endothelial growth factor in these cels was examined by western blot assay. Rat platelet activation in different groups was determined by flow cytometry.
RESULTS AND CONCLUSION:Implanted stem cels were able to grow adherently on the stainless steel stent wal. When the planting cellconcentration was 1×107 cels/L, the cels and organeles were morphologicaly
normal and covered the stent surface wel. These coated cels also expressed vascular endothelial growth factor, suggesting that they functioned as endothelial cels, and they also significantly lowered platelet activation. When
co-cultured with 1×107/L bone marrow mesenchymal stem cels, the stent was covered wel with endothelial-like cels and had significant lower platelet activationin vivo.
