[Objective]To forecast the sponge mechanism mediated by LOC389023 in patients with intractable temporal lobe epilepsy(TLE),through investigating the expression of microRNA interacted with dipeptidyl peptidase 10(DPP10)and LOC389023.[Methods]The expression of DPP10 and Kv4.3 were detected in 15 temporal neocortex from patients with brain trauma (control group)and in 26 temporal neocortex from patients with intractable TLE(epilepsy group)by western blot(WB)and immunohisto?chemical(IHC)staining. The location of DPP10 and voltage dependent potassium channel 4.3(Kv4.3)was detected by immunofluo?rescent(IF)staining. The interaction between DPP10 and Kv4.3 was testified by co-immunoprecipitation(Co-IP). The expression of microRNA obtained by softwares(miRanda,Pita,TargetScan and miRDB)was detected by qPCR.[Results]IHC and WB showed an increased expression of DPP10(P<0.05)and a decreased expression of Kv4.3(P<0.05)in the epilepsy group. IF showed that the DPP10 and the Kv4.3 co-expressed in the membrane and the cytoplasm of neurons. Co-IP showed obvious interaction between the DPP10 and the Kv4.3.Five microRNA(miR-32-5p,miR-140-5p,miR-367-3p,miR-25-3p,miR-4325)were obtained by soft?wares. No significant differences in the expression of miR-32-5p and miR-4325 were found between epilepsy group and control group by qPCR(P>0.05). But decreased expression of LOC389023 and miR-140-5p and increased expression of miR-25-3p and miR-367-3p were found in epilepsygroup compared to control group (P < 0.05).[Conclusion]miR-25-3p and miR-367-3p may be regulated by LOC389023 through the sponge mechanism followed by altered expression of DPP10 in intractable temporal lobe epilepsy.

BACKGROUND: Chinese medicine xinmailong (XML) injection is a kind of new nucleoside compound which comes from American giant cockroach of insects. A lot of studies show that XML has obvious effect on cardiovascular activity which can treat acute or chronic congestive heart failure and shock and improve microcirculation.OBJECTIVE: To observe the effect of XML on anti-aging of mice.DESIGN: Controlled observational study.SETTING: Department of Physiology and Pathology, Basic Medical College of Dali College.MATERIALS: The experiment was carried out at the Functional Laboratory of Basic Medical College between July 2002 and September 2004. A total of 40 ICR mice of both sexes were provided by Kunming Medical College,Yunnan Naturally Occurring Drugs Key Laboratory. XML injection was provided by Yunnan Tengchong Pharmacy Factory [batch number: 94 (ZL) 03].METHODS: A total of 40 ICR mice were randomly divided into 4 groups:young control group, aging control group, XML group at high dosage and XML group at low dosage with 10 in each group. All mice were fed routinely with standard feed. Mice in young control group aged 3 months and weighed (20±2) g; meanwhile, mice in other groups aged 20 months and weighed (40±3) g. From the 20th month, mice in XML groups were intraperitoneally injected with 6 mg/kg and 8 mg/kg, respectively, for 30 days with once every day. Mice in young and aging control groups were intraperitoneally injected with the same volume of saline. On the 31st day,heads of mice were cut off to obtain blood which was maintained at hepalean anti-coagulated tube. Brains and livers were obtained rapidly for homogenate with 10% saline. Activities of catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in serum, content of malondialdehyde (MDA) in brain tissue and content of lipofuscin in cerebral and hepatic tissue were measured according to introduction of kits.MAIN OUTCOME MEASURES: ① Activities of CAT, SOD and GSHPx in serum; ② content of MDA in brain tissue and contents of lipofuscin in cerebral and hepatic tissues.RFSULTS: A total of 40 animals were involved in the final analysis without any loss. ① Activities of CAT, SOD and GSH-Px in serum of mice were lower in aging control group than those in young control group; however,activities of CAT, SOD and GSH-Px in serum of mice were increased in the two XML dosage groups, and there was significant difference from those in aging control group (P ＜ 0.05 or P ＜ 0.01). ② Content of MDA in brain tissue and contents of lipofuscin in cerebral and hepatic tissues of mice in aging control group were higher than those of mice in young control group, but those in the two dosage groups were decreased, which was significant difference from those of mice in aging control group (P ＜ 0.01). However, there was no significant difference between the two dosage groups.CONCLUSION: XML has an effect on anti-aging through improving metabolism of free radicals.

ObjectiveTo identify the risk factors related to the mortality of severe acute pancreatitis.Methods Clinical data of 57 cases of severe acute pancreatitis in our hospital from August 1997 to February 2004 were collected and analyzed retrospectively. There were 32 males and 25 females. The median age was 51 years. Cases were divided into death group and survival group according to their outcome. The characteristics, severity and surgical therapy were analyzed. ResultsEleven patients died, the mortality was 19.3%。 Thirty cases underwent surgery, 8 died, the mortality was 26.3%.Factors which were of significant differences between the two groups by univariate analysis were age, Ranson score, APACHEⅡscore, ascites, MODS, ARDS, heart failure and renal failure. Multivariate logistic regression showed that independent risk factors included age, ascites, MODS. ConclusionsIn case of severe acute pancreatitis,the independent risk factors related to mortality were age, ascites and MODS.

OBJECTIVETo investigate the expression of La protein in cervical cancer tissues and explore its role in the occurrence and progression of cervical cancer.

METHODSThe expression of La protein in cervical cancer and normal cervical tissues was detected by immunohistochemical staining. RNA interference technology was used to silence La protein expression in HeLa cells and the changes in cell proliferation, tumor sphere formation and cell cycles were investigated.

RESULTSThe expression of La protein was significantly higher in cervical cancer tissues than in normal cervical tissues (61% vs 9%, P<0.05). Silencing La protein expression in HeLa cells caused significantly reduced the cell proliferation and lowered the tumor sphere formation rate from the control level of (17.1=1.92)% to (6.3=0.45)% (P<0.05), resulting also in G0/G1 cell cycle arrest and reduced cyclin D1 protein expression.

CONCLUSIONThe RNA binding protein La can promote the development of cervical cancer and may play a critical role in the carcinogenesis and progression of cervical cancer.

Objective To investigate the early resuscitation effect of hemoglobin-based oxygen carriers (HBOC) in rats with uncontrolled hemorrhagic shock.Methods 170 Sprague-Dawley (SD) rats were randomly divided into five groups:lactate Ringer solution (LR) control group,whole blood control group,and 0.5％,2.0％,5.0％ HBOC groups,with 34 rats in each group.The uncontrolled hemorrhagic shock model in SD rats was reproduced by cutting off the splenic artery branch,and induced mean arterial pressure (MAP) reducing to 40 mmHg (1 mmHg =0.133 kPa).The corresponding solution was infused after model reproduction in each group,maintaining MAP at 50 mmHg for 1 hour,then completely ligating and hemostasis,and maintaining MAP at 70 mmHg for 1 hour and 80 mmHg for 1 hour respectively,after maintaining MAP 80 mmHg,all were supplemented with LR to 2 times blood loss volume.The survival rate and blood loss rate were observed in 16 rats in each group,hemodynamics parameters including MAP,left ventricular systolic pressure (LVSP) and the maximum rate of left ventricular pressure rise (+dp/dtmax) were determined in another 10 rats,and cardiac output (CO) and tissue oxygen supply (DO2) were observed in the rest 8 rats.Results ① When resuscitation by LR alone,the blood loss rate of animals was as high as 60％ to 70％.Compared with the LR control group,whole blood recovery could significantly reduce the blood loss rate before hemostasis in uncontrolled hemorrhagic shock rats [(46.6 ± 4.5)％ vs.(62.3 ± 4.0)％,P ＜ 0.01];0.5％,2.0％,5.0％ HBOC could significantly decrease the blood loss rate,especially in 5.0％ HBOC group with significant difference as compared with that in the LR control group [(45.6±4.1)％ vs.(62.3±4.0)％,P ＜ 0.01].② When LR was used alone for resuscitation,the rats died quickly and survived for a short time.Only one rat survived for 12 hours,and no rat survived for more than 24 hours.Compared with the LR control group,whole blood resuscitation could improve the survival rate of uncontrolled hemorrhagic shock rats,and the survival time was significantly prolonged (hours:20.4± 4.6 vs.3.5 ± 1.1,P ＜ 0.01);0.5％,2.0％ and 5.0％ HBOC also significantly prolonged the survival time of rats.The 5.0％ HBOC group had the best effect,4 rats survived in 24 hours,and the survival time was significantly longer than that of the LR control group (hours:18.4 ± 4.0 vs.3.5 ± 1.1,P ＜ 0.01),and it was the same as the whole blood control group.③ Compared with pre-shock,CO,DO2 and hemodynamic parameters of uncontrolled hemorrhagic shock rats were significantly decreased,and the above parameters were gradually increased with the prolongation of rehydration time.Compared with the LR control group,whole blood resuscitation could significantly increase CO and DO2,and improve hemodynamics in rats with uncontrolled hemorrhagic shock at different time points.Three concentrations of HBOC could also increase CO,DO2 and other hemodynamic parameters of rats at 1 hour of maintaining MAP of 80 mmHg after hemostasis and 1 hour and 2 hours after resuscitation.The effect of 5.0％ HBOC group was more significant than that of the LR control group with statistically significant difference [CO (× 10-3,L/min):72.84±2.84 vs.63.11±2.38 at 1 hour of maintaining MAP of 80 mmHg,70.25±4.55 vs.59.88 ± 9.31 at 1 hour after resuscitation,71.51 ± 2.90 vs.53.24 ± 6.32 at 2 hours after resuscitation;DO2 (L· min-1 · m-2):271.9± 13.5 vs.159.1 ±25.4 at 1 hour of maintaining MAP of 80 mmHg,261.0± 15.0 vs.145.7±20.1 at 1 hour after resuscitation,249.6± 12.0 vs.107.4± 18.2 at 2 hours after resuscitation;MAP (mmHg):82.1±2.1 vs.74.0±2.8 at 1 hour of maintaining MAP of 80 mmHg,107.5±9.3 vs.64.0±5.7 at 1 hour after resuscitation,104.0±9.7 vs.73.0±4.2 at 2 hours after resuscitation;LVSP (mmHg):128.6±7.9 vs.103.8±0.8 at 1 hour of maintaining MAP of 80 mmHg,129.3±± 15.0 vs.99.4±0.0 at 1 hour after resuscitation,127.5± 11.3 vs.97.4±0.0 at 2 hours after resuscitation;+dp/dt max (mmHg/s):6 534.2±± 787.6 vs.5 074.0± 71.7 at 1 hour of maintaining MAP of 80 mmHg,5 961.5 ±± 545.4 vs.4 934.5 ± 510.2 at 1 hour after resuscitation,5 897.4± 350.5 vs.4 534.7 ±489.2 at 2 hours after resuscitation,all P ＜ 0.05].Conclusions HBOC infusion prolonged the survival time,increased survival rate,and improved hemodynamics,cardiac function and tissue oxygen supply in a dose-dependent manner in the early stage of uncontrolled hemorrhagic shock.The recovery effect of 5.0％ HBOC was similar to that of the whole blood.

Objective:To explore the prognostic factors of patients with gallbladder cancer in different anatomical locations.Methods:A retrospective analysis of the clinical data of 140 patients with gallbladder cancer who were surgically treated in the 904 Hospital of the Joint Logistics Support Force from January 2015 to December 2015. Among them, 49 were males and 91 were females, with a median age of 64.0 years. According to the location of gallbladder cancer, they were divided into the neck of the gallbladder and the bottom of the gallbladder. The clinical data of the two groups were compared. The Kaplan-Meier method was used for univariate analysis, and Cox multivariate regression analysis was used to analyze the significant factors of univariate survival to determine the independent risk factors that affect the prognosis of patients with gallbladder cancer. Use Pearson correlation to analyze the correlation between clinicopathological characteristics.Results:Patients in the neck of the gallbladder group had higher levels of preoperative total bilirubin, preoperative albumin, carcinoembryonic antigen, carbohydrate antigen 19-9, extrahepatic bile duct resection (biliary-enteric anastomosis), radical resection, breakthrough of the liver/serous membrane invasion, lymph node metastasis, TNM staging, local recurrence in the operation area in the surgical area were statistically significant ( P<0.05). Univariate analysis suggested that preoperative jaundice, Glasgow prognostic score (GPS), C-reactive protein, carcinoembryonic antigen, carbohydrate antigen 19-9, accidental gallbladder cancer, surgical method, tumor pathological type, tumor differentiation degree, tumor growth location (neck than the bottom of the body) are related to the prognosis (all P<0.05). Cox regression analysis indicated that GPS ( RR=3.272, 95 CI: 1.987-5.388), surgical method ( RR=4.149, 95 CI: 2.561-6.723), tumor location ( RR=0.316, 95 CI: 0.209-0.478), distant metastasis ( RR=1.695, 95 CI: 1.036-2.775) and TNM staging ( RR=3.686, 95 CI: 2.222-6.115) are independent risk factors affecting the prognosis of gallbladder cancer. Correlation analysis suggests that neck tumors are related to later staging, liver bile duct invasion, lymph node metastasis, high inflammation levels, and low radical cure rates. Conclusions:Gallbladder cancer that occurs in the neck of the gallbladder is an independent factor influencing the poor prognosis of patients with surgical treatment. In addition, TNM staging, distant metastasis and Glasgow score are important predictors of survival in patients with gallbladder cancer.
