Objective To identify whether cisplatin can induce autophagy of bladder cancer T24 cells and the possible mechanism, and to observe the relationship between outophagy and apoptosis.Methods MTT assay was applied to investigate the effects of various concentration of cisplatin( 0 , 10 , 20 and 40 μg/mL) on T24 survival.TEM was performed to detect the autophagosome formation .Western blot assay was used to analyze the expression changes of LC3-Ⅱ, P62 and extracellular signal-regulated kinase ( ERK1/2 ) and p-ERK at the protein level.The effects of autophagy on the survival and apoptosis of bladder cancer cells were investiga-ted.Results DDP observably inhibited proliferation of bladder cancer cells in a dose-dependent manner ( P<0.05), the 50% inhibiting concentration(IC50) was (30.3 ±2.4)μg/mL;DDP induced autophagy of bladder cancer cells, observably increased autophagosome induced by DDP; up-regulated expression levels of LC3-Ⅱproteins ( P<0.05 ) , down-regulated expression of P62 proteins ( P<0.05 );DDP increased the protein level of p-ERK (P<0.05); The inhibitor of ERK pathway U0126 inhibited DDP-induced autophagy, as evidenced by decrease in the expression of LC3-Ⅱproteins ( P<0.05 ) .After inhibition of autophagy by WTM in DDP-treated cells, cell viability was obviously decreased and apoptosis was increased (P<0.05);DDP combined with WTM observably enhanced cleavage of poly ADP-ribose polymerase 1 ( PARP-1 ) and cleaved-caspase-3 which is apop-tosis related proteins ( P<0.05 ) .Conclusions Autophagy can protect T24 cells against ciplatin-induced apop-tosis, the possible mechanism of autophagy is the ERK signaling pathway is activated .

Objective To investigate the clinical features and genetic basis of cryopyrin-associated periodic syndrome (CAPS). Methods The clinical manifestations, laboratory tests, and genetic tests of one case of CAPS were retrospectively analyzed. The related literatures were reviewed. Results A 7 year and eight month old male patient had recurrent fever for 7 years and his whole body was covered with patchy red rash which was itchy and faded with pressure. The limbs and joints were normal. The levels of high-sensitivity C-reactive protein, erythrocyte sedimentation rate, rheumatoid factors were increased. The patient had fundus arteriosclerosis, double conjunctival lesions and nerve deafness on both sides. There was no mutation found in NLRP3 gene coding region, but a heterozygous mutation (-2667G>T) had been found in 5 ' untranslated region. Compared with normal control, the mRNA level of NLRP3 increased 4.2 times and the expressions of IL-1βand IL-18 gene increased 2.2 (P=0.002) and 1.2 times (P>0.05). Conclusions The clinical features of CAPS can be recurrent fever, rash, and joint involved. The oph-thalmologic abnormalities and varying degrees of deafness may occur during the progression. The test of NLRP3 gene may help diagnosis.

As a kind of source wide,low inherent immnunogenicity multipotent stromal cells,mesenchymal stem cells (MSCs) have been used to cell-based therapeutic researches of immunodeficient deseases or other severe clinical disorders.Despite low levels of engraftment in the injured lung,numerous preclinical trials indicate that mesenchymal stem cells can promote damaged tissue repair constructed by secreting paracrine factors to regulate the host immunity,inhibit inflammation and restore epithelial integrity.Acute lung injury(ALI) is a serious organ dysfunction occurred earliest and the most commonly affected organ.Currently there is no effective medicine therapy and the mortality remains high.Researches demonstrate MSCs can reduce alveolar edema,improve lung function and reduce motality.So understanding of the mechanism will be conductive to the MSCs from experimental stage into clinical application.This issue will put a brief overview pointed on the mechanism of mesenchymal stem cells in repairing the injured lung.

Objective To investigate the effect of different forbidden drink schemes on anesthesia induction and postoperative nausea and vomiting during pediatric interventional heart surgery.Methods One hundred and twenty pediatric patients underwent cardiac interventional procedures under general anesthesia were randomized into group A,B and C,with 40 patients in each group.Patients in cach group were fasted for 8 h preoperatively.Water was prohibited for patients in group A for 6 h preoperatively.Patients in groups B and C orally took 10％ glucose solution and a multivitamin drink (Outfast) at 2 h preoperatively,respectively.Nausea and vomiting after anesthesia induction were recorded for 24 h postoperatively.Results The sedation and mask acceptance scores were significantly higher in group B and C than those in group A,and were significantly higher in group C than those in group B (P ＜ 0.05,resoectively).Following anesthesia induction,MAP was significantly higher in group B and C than that in group A (P ＜ 0.05,resoectively).Both the severity and incidence of postoperative nausea and vomiting were higher in group B and C than those in group A,and was lower in group C than that in group B (P ＜ 0.05,resoectively).Conclusions Taking clear water orally 2 hours before surgery can decrease the restlessness of pediatric interventional heart surgery during anesthesia induction period,with stable smooth hemodynamics,reducing the degree of PONV.

Objective To describe and analyze the distribution of medical expenditure of Liaoning province in 2014 in terms of population beneficiary based on the System of Health Accounts 2011(SHA 2011).Methods By means of multistage and stratified sampling, a total of 252 medical institutions were selected from four cities in Liaoning province according to their economic status and geographical distribution.Macro data including the outpatient income and hospitalization income were taken into account, to calculate the beneficiary population of the province in 2014 according to SHA2011.Results GBD classification found that the highest medical expenditure category was non-communicable diseases, accounting for 63.02% in total medical expenditure.ICD classification found that respiratory disease as consuming the highest medical expenses (43.76%).The average medical expenditure of the elderly population was the highest per person, up to 3 041.70 yuan per person.Conclusions Medical expenses of non-communicable diseases, respiratory disease and elderly population were still high.Thus we need to emphasize disease prevention, and take efficient measures against such key diseases to curb the medical expenses.The elderly population calls for specific and effective measures to reduce their medical expenses.
