Objective　To discuss the possibility of ultrasonic superficial spray anesthesia applied to bronchoscopy in children with intratracheal foreign bodies. Methods　50 cases with intratracheal foreign body were divided into two groups: surface anesthesia group (S group) and intravenous anesthesia group (Ⅰ group). 2% Lidocain by ultrasonic spraying inhalation for 8～10 min and r-OH 80 mg*kg-1+Ketamine 1 mg.kg-1 intravenous injection were adminstered respectively. Results　In S group perioperative the MAP and HR were stable， the complications were fewer and the SpO2 was >95%，the awaking time was shorter (70.1±15.3) min after operation；In I group the MAP and HR were descendent (P<0.05)， the complications were more and the SpO2 was <95% (P<0.05)， the awaking time was longer(P<0.01). Conclusion　The surface anesthesia is effective.The MAP and HR are stable，the complications are fewer and the awaking time is shorter.

ABSTRACT:Many studies show that helminth‐derived molecules can induce immunoregulatory cells to form immune net‐work‐mediated immune ,thereby inhibiting allergic and autoimmune diseases .Helminth parasites can induce immune cell activa‐tion and produce cytokine .And parasites play an inhibitory effect to affect other immune related diseases .However ,the associ‐ation between helminths infections and immune related diseases does not always have an unequivocal outcome .While some hel‐minths infections protect against allergic diseases ,other helminth can exacerbate this immunopathology .

Objective To evaluate the safety and effectively of transfusion plan guided by POTTS in gynecological patients with Hb level ranged from 60 to 100 g/L. Methods 114 gynecological patients with perioperative Hb level ranged from 60 to 100 g/L were randomly divided into POTTS group ( n=57 ) and control group ( n=57 ) . Patients in POTTS group received transfusion under the guidance of POTTS. Patients in control group received transfusion according to doctor's experience. The proportion of injecting RBCs,the amount of RBCs, the incidence of serious complications and mortality,ICU occupancy rate, postoperative Hb recovery, incision healing, hospitalization time, blood transfusion related costs and costs of hospitalization were observed and compared. Results The transfusion rate and volume in POTTS group were significantly lower than the control group ( P<0. 01 ) . Neither severe com-plications nor any mortality were found in each group. The transfusion costs in POTTS group were significantly less than the control group (P<0. 01). Two groups had no postoperative ICU admission;the postoperative Hb recovery, incision healing, hospitalization time and costs of hospitalization in two groups were not statistically significant. Conclusion POTTS could be safety and effectively used in gynecological patients with Hb level ranged from 60 to 100 g/L, also effectively save the blood, reduce the costs of blood transfusion, not increase perioperative mortality and the incidence of various complications.

AimTo study the effect of extracts of ginkgo biloba leaves(GbE) on apoptosis in neuronal cells. Methods Primary cerebral cultures from rat fetus were used to observe the activity of neuronal cells and to determine the release of LDH and DNA gel electrophoresis. Results Gb E enhanced the activity of neuronal cells, decresed the release of LDH,and relieved the structural changes of nucleus and DNA fragmentation. Conclusion GbE can inhibit apoptosis in neuronal cells.

Objective To evaluate in vivo tracking of swine mesenchymal stem cells (MSCs) la-beled with super paramagnetic iron oxide (SPIO) in intraportal transplantation by a clinical 1.5T MR.Methods MSCs were isolated from swine and cultured as well as expanded, which were then incuba-ted with SPIO (Feridex I. V.). Prussian blue staining was performed for showing intracelluar irons.To establish a swine model of acute liver necrosis, 0.5 g/kg of D-galactosamine was administrated to 10 pigs. MSCs(labeled cells in six, unlabeled cells in four)were injected into liver via portal veins. MR imaging was performed with a clinical 1.5T MR immediately before and at 6 h, 3 d, 7 d, 14 d after transplantation, respectively. Results Prussian blue staining of SPIO labeled MSCs could be effec-tively labeled and the labeling efficiency was almost 100%. Signal intensity loss in liver by SPIO labe-ling on FFE sequence persisted until 14 days after transplantation. Histological analysis by Prussian blue staining showed homing of labeled MSCs in liver after 14 days, primarily distributing in hepatic sinusoids and liver parenchyma. Conclusion MSCs can be labeled with SPIO in vitro successfully.MRI can monitor magnetically labeled MSCs transplanted into liver.

Objective To understand the endemic characteristics and regularity of cystic echinococcosis by evaluating and classifying its endemic situation in Non Tibetan Plateau regions,so as to provide the evidence for formulating effective preventive and control measures. Methods The prevalence data of cystic echinococcosis in 174 counties(cities,districts,banners)in Non Tibetan Plateau regions from a national survey were collected and analyzed by the sample cluster method in 2012. Results The 174 counties(cities,districts,banners)could be classified into 4 clusters by spatial distribution. The first cluster with human high prevalence rate,low infection rate of livestock,and positive rate of dog stool antigen included 3 counties. The second cluster with high infection rate of livestock,low prevalence rate of human,and positive rate of dog stool antigen included 20 counties(cit-ies). The third cluster with high positive rate of dog stool antigen,low prevalence rate of human,and low infection rate of livestock included 39 counties(cities,districts,banners). The fourth cluster with low rates of the above 3 indices included the rest 112 counties. Conclusions The results of the cluster analysis conform to the current epidemiological status of cystic echinococcosis in the Non Tibetan Plateau regions. The epidemiological characteristics and geographical distributions of the four area types will pro-vide a basis for the classified management and guidance of cystic echinococcosis control in these areas.

CONCLUSION: Sansheng Huatan Decoction combined with chemotherapy is a better treatment for non-small-cell lung cancer as compared with chemotherapy.

Objective To retrospectively analyze the influence of perioperatively transfusing different ratios of fresh frozen plasma (FFP) to red blood cell (RBC) on prognosis of patients receiving massive transfusion.Methods From January 2010 to September 2012,139 surgical patients with transfusion of ≥ 10 RBC units within 24 hours were included in the study.Patients were categorised into three groups based on the FFP ∶ RBC scale:high scale group (FFP ∶ RBC ＞ 1 ∶ 1,n =19),middle scale group (FFP ∶ RBC =1 ∶ 2-1 ∶ 1,n =43) and low scale group (FFP ∶ RBC ＜ 1 ∶ 2,n =77).Comparison among the groups was made in aspects of transfusion of different blood products in hospital,blood routine index before and after massive transfusion,blood coagulation index,electrolyte index,hospital stay,ICU stay,cure rate and mortality.Results FFP transfusion was the most in high scale group (2 600 ± 1 582) ml,followed by (1 390 ± 1 043) ml in middle scale group and (318 ± 342) ml in low scale group (P ＜0.05).Platelet (PLT) transfusion was more in high scale group (0-1.4 units) and middle scale group (0-1.0 units) compared with that in low scale group (0-0.0 units,P ＜ 0.05).Volume of RBC and cryoprecipitate transfused revealed no significant differences among the groups (P ＞ 0.05).Before blood transfusion prothrombin time (PT) [(20.2 ± 10.7) s] and activated partial thromboplastin time (APTT) [(57.2±45.8) s] in middle scale group were significantly prolonged than those in high scale group [(14.3 ±4.4) s and (35.3 ± 10.0) s] and low scale group[(12.5 ± 1.7) s and (31.5 ± 5.9) s] (P ＜ 0.05),but the differences were insignificant in indices of hemoglobin (Hb),PLT,international normalized ratio (INR),K +,and Ca2 + (P ＞ 0.05).After blood transfusion Hb [(106.8 ± 31.7) g/L] and Ca2+[(1.99 ± 0.24)mmol/L] in low scale group were higher than these in middle scale group [(82.5 ± 32.2) g/L and (1.76 ± 0.38) mmol/L] and in high scale group [(91.3 ± 19.1) g/L and (1.96 ±0.25) mmol/L] (P ＜0.05),but there were no significant differences in PLT,PT,INR,APTT and K+(P ＞ 0.05).Moreover,hospital stay,ICU stay,cure rate and mortality were not differed significantly among the groups (P ＞ 0.05).Conclusion For massive transfusion patients,transfusion of FFP and RBC at a 1 ∶ 2 to 1 ∶ 1 ratio is beneficial to preventing coagulation dysfunction and reducing plasma total infusion volume,and exerts no effect on the prognosis.

Objective The core mechanism of renal insterstitial fibrosis (RIF) is epithelial-mesenchymal transition.This study aimed to investigate the effect of erythropoietin on high glucose-induced epithelial-mesenchymal transition ( EMT) of normal hu-man kidney proximal tubular epithelial cells (HK-2) and its possible mechanism. Mothods HK-2 cells cultured in vitro were ran-domly divided into a blank control group , a high glucose induction group , a mannitol induction group , an EPO induction group , an EPO (5, 10, and 20U/mL) inhibition group, and an Rho kinase inhibitor group.After 24 hours of intervention, the mRNA levels of RhoA and ROCK were determined by RT-PCR, those of E-cadherin and α-smooth muscle actin (α-SMA) proteins detected by immu-nofluorescence staining , and the expression of FN proteins in the supernatant measured by ELISA . Results Compared with the blank control group , the expressions of RhoA and ROCK 1 mRNA were significantly increased in the high glucose induction group (0.945 ±0.132 vs 1.400 ±0.022, 1.007 ±0.002 vs 1.913 ±0.011, P<0.05), but markedly decreased in the 5, 10, and 20U/mL EPO inhibition groups (1.400 ±0.022 vs 1.278 ±0.006, 1.400 ±0.022 vs 0.770 ±0.005, 1.400 ±0.022 vs 0.334 ±0.009, P<0.006) in comparison with the high glucose induction group , and the effects were related to the concentration of EPO .Compared with the blank control, the expression of E-cadherin protein was increased in the high glucose induction group (0.644 ±0.006 vs 0.107 ± 0.004, P<0.05), but remarkably decreased in the 5, 10, and 20 U/mL EPO inhibition groups (0.236 ±0.006, 0.433 ±0.010, 0.521 ±0.010) in comparison with the high glucose induction group (P<0.05), and the effects were also related to the concentration of EPO.Pearson correlation analysis showed a positive correlation between the mRNA expressions of RhoA and ROCK 1 in the high glu-cose induction and EPO inhibition groups . Conclusion EPO can inhibit high glucose-induced epithelial-mesenchymal transition of normal human kidney HK-2 cells and thus delay renal fibrosis , which mignt be related to the RhoA/ROCK signaling pathway .
