Background An ethylnitrosourea(ENU)-induced mutant strain C57BL/6 mouse model has been established by our research group.This model is proved to have the spontaneous phenotype of corneal opacity and the typical pathological process similar to human keratitis.Therefore,this model is expected to be a good animal model in the research of the mechanism,hereditary property,and development of drugs for corneal infectious diseases.Objective The present study is to investigate the biological features of opportunistic pathogens using a mouse Staphylococcus-infected corneal model(C57BL/6 mouse) induced by N-ethyl-N-nitrosourea(ENU),and offers an evidence of stability in this animal model.Methods Ten-week-old male C57BL/6 mice were treated with ENU at 150mg/kg by intraperitoneal injection,and then mated with female mice after 60 days.Corneal opacity mutant mice in the F1 generation were selected to backcross with C57BL/6 mice.The bacteria were isolated from the eyeballs of the mutants and cultivated,purified and identified.Drug sensitivity assay was carried out to screen for effective antibiotics for clinic medical care.Results The staphylococcus-infected corneal mouse model(B6-Co) was established successfully,and the Staphylococcus sciuri strain was separated and purified,and then the sensitive antibiotics were distinguished from resistant ones.The sensitive drugs for Staphylococcus sciuri included azithromycin,clindamycin,chloramphenicol,gentamicin,rifampicin,tetracycline,amikacin,sulfamethoxazole compound sinomin,minocycline,levofloxacin,cephalothin,cefotaxime,and furazolidone;whereas this Staphylococcal strain was resistant to cefoxitin,penicillin,ampicillin,novobiocin.Nitrofurantoin showed an intermediate sensitivity.Conclusion The C57BL/6 mouse model is a spontaneous-derived animal model that is infected by coagulase-negative staphylococci,among which the most abundant strain is Staphylococcus sciuri.

Objective To investigate the effect of Amikacin and prulifloxacin alternate application in the treatment of Lung infections in ICU resistant Acinetobacter Bauman.Methods 82 cases of Lung infections in ICU resistant Acinetobacter Bauman from August 2014 to August 2016 in our hospital were selected and randomLy divided into two groups, 41 cases in control group were given routine treatment, 41 cases in the experimental group were treated with Amikacin and prulifloxacin alternate application, and patients were treated continuous for two weeks.Levels of serum CRP, PCT, WBC, N%, SCR, BUN, AST, ALT, scores of APACHE II and CPIS and clinical efficacy were observed pre-and post-treatment.Results After two weeks, levels of serum CRP, PCT, WBC and N% in experimental group were significantly lower than control group, scores of APACHE II and CPIS were significantly lower than the control group, the total clinical efficiency was higher than the control group(P<0.05), and the levels of serum SCR, BUN, ALT, AST were lower, but had no statistically difference.Conclusion Amikacin and prulifloxacin alternate application in the treatment of Lung infections in ICU resistant Acinetobacter Bauman can reduce the patient's inflammatory reaction and the degree of infection.

OBJECTIVE To evaluate the anti-tumor activities of WX-127-07,a new microtubule-tar-geting agent invitroand probe its molecular mechanism. METHODS The well-known microtubule-targe-ting anti-tumor drugs taxol,vincristine and anti-gout drug colchicine were used as positive controls. The anti-proliferation activity was examined in five different cell lines after treatment with WX-127-07(0.3 -300 nmol·L-1 )for 72 h by SRB assay. The cell cycle arrest profile was assayed by flow cytometry. The multiparameters of cytotoxicity,cell morphology,apoptosis and different signaling pathways related to tumorigenesis and inflammation were analyzed using the high content analysis platform. Tubulin tryptic digestion and competition inhibition assay for colchicine or vinblastine site were used to confirm the bind-ing site in microtubules at a molecular level. RESULTS All the tested compounds obviously inhibited the growth of A549,HepG2,HeLa,HLF and HUVEC cells. The lC50 values of WX-127-07 were 4.47±0.05, 5.18±0.08,4.90±0.19,4.10±0.16 and(5.04±0.08)nmol·L-1 respectively,lower than those of colchicine〔the lC50 values were 21. 17 ± 1. 22,14. 19 ± 0. 53,43. 80 ± 1. 64,145. 89 ± 10. 97 and( 27. 67 ± 1.79)nmol·L-1 ,respectively〕and those of vincristine〔the lC50 values were 16.51±0.36,16.76±0.33, 27.80±2.75,43.80±1.48 and(9.15±0.78)nmol·L-1 ,respectively〕,but were similar to or lower than those of taxol〔the lC50 values were 10. 68 ± 0. 61,12. 86 ± 0. 25,4. 81 ± 0. 61,102. 07 ± 15. 17 and( 3. 04 ± 0.12)nmol·L-1 ,respectively〕. High content multi-parameter analysis revealed that WX-127-07 induced a concentration-dependent microtubular depolymerization(P=0.0075)with the same pattern as colchicine and vincristine,but at a lower concentration. Both WX-127-07 and positive drugs could induce cell cycle arrest in A549 cells,increase nuclear membrane permeability and early signs of apoptosis in HepG2 cells,but neither cancer related pathways nor inflammation related pathways were affected. Microtubular competition inhibition assay showed that WX-127-07 inhibited the binding of colchicine with tubulin(P =0.0259). Tryptic digestion of tubulin-WX-127-07 premixture showed a similar electrophoretic band to that of tubulin-colchicine premixture. CONCLUSION WX-127-07 is a novel microtubule-depolymerizing agent with anti-proliferation activity and acting on the colchicine binding site.

Objective To obtain more physiological data of Leptin knockout SD rats available for the user , the long-term observation of fasting blood glucose and pathological phenotypes were performed .Methods The protein expression levels in liver tissues were determined by western blot .Body weight of Leptin knockout rats ( Leptin-/-) and littermate lean rats (Leptin+/+) were weighed up at 1,3,6,8 months of age.Fasting blood glucose of Leptin +/+rats and Leptin-/-rats at 1,3,6,8 months of age were measured using One Touch? brand blood glucose monitoring systems.Pathological changes of pancreas and livers of Leptin -/-rats were observed by the method of HE staining and Immunohistochemistry (IHC).Results Short null Lepin proteins were expressed in liver tissues from Leptin -/-rats.

After that, blood glucose values decreased and eventually become nearly normal at 8 months of age.Pathological examination indicated that Leptin -/-rats at 8 months of age had a fatty liver , more pancreas islets with lager volume and more beta cells with increased insulin secretion .Conclusion Leptin-/-rat were characterized by obesity , fatty liver, islet cell hyperplasia and early hyperglycemia .

Objective To study the clinical efficacy of ulinastatin combined with ambroxol hydrochloride in the treatment of acute respiratory distress syndrome (ARDS) complicated with ventilator-associated pneumonia (VAP).Methods One hundred and ten cases of ARDS complicated with VAP were randomly divided into the study group (55 cases) and the control group (55 cases) according to the different treatment method.The two groups accepted symptomatic anti-infective treatment,and the control group was treated with 300mg of ambroxol twice daily,the study group were intravenously infused 200 000U ulinastatin on the basis of the control group,two groups of patients were treated for 1 week.The ventilation indicators,pathogen clearance rate,off-time rate,mechanical ventilation time,respiratory rate,APACHE score,lung injury score and adverse reactions during the treatment were compared between the two groups.Results After treatment,PaO2,PaO2/FiO2,CL,RAW and PIP in the study group were (97.83 ± 12.01)mmHg,(364.25 ±35.77)mmHg,(88.93 ±9.44)mL/cmH2O,(31.45 ±4.87)cmHH2O · L-1 · s-1,(21.43 ± 5.75)cmH2O,respectively,which in the control groupwere (83.25 ± 10.13)mmHg,(238.55 ± 34.29) mmHg,(62.77 ± 8.54) mL/cmH2 O,(37.97 ± 6.54) cmH2 O · L-1 · s-1,(29.12 ± 5.43) cnH2 O,respectively.The P.aO2,PaO2/FiO2,CL in the study group were significantly higher than those in the control group,the RAW,PIP in the study group were significantly lower than those in the control group,the differences were statistically significant (t =6.88,18.81,5.93,7.21,15.42,all P ＜ 0.05).The clearance rate of both Gram-positive lacteria (90.00％)and Gram-negative bacteria (92.00％) in the study group were significantly higher than those in the control group (66.67％ and 70.21％) (x2 =4.81,8.84;P =0.03,0.00).The mean mechanical ventilation time in the study group [(7.15 ± 2.43) days] was significantly shorter than that in the control group [(12.85 ± 3.12) days] (t =10.69,P ＜ 0.05).The respiratory rate,APACHE score and lung injury scores of the two groups were significantly lower than those before treatment (P ＜ 0.05).The respiratory rate,APACHE scores and lung injury scores of the study group [(18.94 ± 6.99) times/min,(12.53 ± 3.14) points,(1.31 ± 0.15) points] were significantly lower than those of the control group [(25.87 ± 6.12) times/min,(16.53 ± 4.42) points,(1.65 ± 0.32) points],the differences were statistically significant (t =5.53,5.47,7.14;P =0.00,0.00,0.00).The off-line success rate and mortality between the two groups had no statistically significant differences (all P ＞ 0.05).Conclusion Ulinastatin combined with ambroxol hydrochloride can significantly improve the respiratory function of ARDS patients complicated with VAP,significantly shorten the duration of mechanical ventilation,improve respiratory function,reduce lung injury and improve pathogens clearance rate,but with no significant impact on mortality.

Objective To investigate the effects of different early enteral nutrient (EN) emulsions of TPF-T and TP on nutritional status and intestinal mucosal barrier in patients with septic shock. Methods From May 2017 to May 2018, 112 patients with septic shock were continuously enrolled in the Department of Intensive Care Unit of the First People's Hospital of Taizhou, and they were randomly divided into a TPF-T group and TP group, each group with 56 cases. After admission, the patients in both groups were all treated according to the 2016 Saving Sepsis Campaign (SSC) Guidelines for septic shock. Both groups were supported with EN, TPT-T group was given TPF-T EN emulsion rich in fish oil, while TP group was supported with standard TP EN emulsion, and the therapeutic course was consecutive 7 days in both groups. The differences in nutritional status, inflammatory response, immune function, intestinal mucosal barrier, gastrointestinal symptoms and prognosis were compared between the two groups. Results After EN, the nutrition indicators such as albumin (Alb), prealbumin (PA), transferrin (TRF) and immune indexes (IgA, IgG), human leukocyte DR antigens (HLA-DR) and D-lactic acid were increased in both groups, reaching the peaks on the 7th day after EN application, Alb, PA, TRF, IgA, IgG, HLA-DR in the TPF-T group were significantly higher than those in the TP group [Alb (g/L): 34.43±5.81 vs. 33.59±5.34, PA (mg/L): 269.83±47.56 vs. 252.67±41.92, TRF (g/L): 3.43±0.64 vs. 3.32±0.81, IgA (mg/L): 159.45±34.56 vs. 143.31±33.81, IgG (mg/L): 4 947.68±871.66 vs. 4 583.75±841.54, HLA-DR: (68.22±9.11)% vs. (62.21±9.69)%], and after EN, the D-lactic acid in the TPF-T group was significantly lower than that in the TP group (mg/L: 30.42±6.79 vs. 33.34±7.31). The inflammatory indicators of tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), procalcitonin (PCT), endotoxin and diamine oxidase (DAO) were all gradually reduced in two groups, reached the lowest levels on the 7th day after EN application, and all the above-mentioned indicators in the TPF-T group were significantly lower than those in the TP group [TNF-α (ng/L):95.43±20.69 vs. 109.59±23.45, CRP (mg/L): 21.33±16.35 vs. 32.36±17.83, PCT (μg/L): 1.24±1.21 vs. 4.18±1.32, endotoxin (U/L): 10.32±2.31 vs. 11.54±2.69, DAO (g/L): 19.45±8.49 vs. 25.47±9.41]. The incidences of gastric retention, diarrhea and paralysis of lower digestive tract in TPF-T group were significantly lower than those in TP group [gastric retention: 14.29% (8/56) vs. 32.14% (18/56), diarrhea: 12.50% (7/56) vs. 35.71% (20/56), paralysis of lower digestive tract: 7.14% (4/56) vs. 23.21% (13/56)], the length of hospital stay was significantly shorter in the TPF-T group than that in the TP group (days: 18.77±5.08 vs. 21.71±6.67, P < 0.05); however, there was no significant difference in mortality between the two groups [14.29% (8/56) vs. 21.43% (12/56), P > 0.05]. Conclusion TPF-T could more effectively maintain nutritional status, reduce inflammatory reaction, improve immunity, protect intestinal mucosal barrier function, and has fewer adverse reactions, which was helpful to improve the prognosis of septic shock patients.

Background:China's accelerating development and increasingly important role in global health engagement create a great demand for global health professionals including international consulting experts.This study reported the detailed development and evaluation of an international consulting training for global health workforce.Methods:Based on Kirkpatrick's model,a mixed-methods approach was used to evaluate the effectiveness of the training.Quantitative and qualitative data on participants' reaction,learning,and application of the learned knowledge and skills were collected by a training evaluation survey at the ending of training and a follow-up interview in three months after the training.Results:Thirty-six participants attended the training and 34 of them completed quantitative investigation.The training satisfaction evaluations were positive,for which participants rated the training program highly and over 90％ of them agreed with the usefulness of the training.About knowledge and skills change,participants showed improved consulting knowledge and skills from pre-to post-training (P ＜ 0.001).A total of 23 participants accepted follow-up interview,and most participants applied knowledge and skills learned from the training in their daily work or study.However,only 30.4％ of participants applied their learning in the consulting program.The largest barrier of application was the lack of consulting opportunities.In addition,almost all the participants reported that they would be glad to attend more training courses in the future.Conclusion:The international consulting training program was well-received,and was feasible to improve the consulting service competence of global health professionals.According to participants' feedback,it is essential to develop and expand consulting training in the field of global health.

Objective To illustrate the semiological characteristics of the three sub-types within the broad bilateral asymmetric tonic seizures (BATS),summarize their predictive values on lateralization and localization of seizure onset zone (SOZ),and analyze the difference between BATS and asymmetrical tonic limb posturing (ATLP).Methods A retrospective review of 385 patients who underwent stereotactic electrode implantation in the Sanbo Brain Hospital,Capital Medical University from September 2011 to May 2018 was performed.As long as there was a clinical epileptic seizure in the presence of BATS or ATLP,the patients were classified into the corresponding groups.Postoperative prognosis was assessed using Engel's grading criteria for a follow-up of no less than six months.Seizure descriptions were based on the classification of epileptic seizures introduced by Lüiders,which used arrows to connect the symptoms in chronological order.Results There was no statistically significant difference between the classic BATS and bilateral proximal tonic seizure in terms of whether it could be an independent seizure,as the onset and end of the seizure,with version and generalized tonic-clonic seizure (P＞0.05).Compared with the ATLP,except for whether it could be an independent seizure (P=1.000) and onset before versive seizure (P=0.068),the BATS showed significantly different semiological features (P＜0.05).The classic BATS and secondary motor area epilepsy had a 100.0％ predictive accuracy on the lateralization of SOZ.In the patients with broad BATS,the SOZ distribution was more extensive,but it was rare in the orbitofrontal gyrus,frontal pole and mesial temporal lobe.Compared with the bilateral proximal tonic seizures from the other regions,those originated from supplementary somatosensory motor area and its adjacent areas were rare and showed no statistically significant difference (0/8 vs 40.0％ (18/45),x2=3.226,P=0.072) but a low trend.The predictive value of BATS on lateralization of SOZ was higher than that of ATLP (84.9％ (45/53) vs 57.1％ (24/42),x2=9.086,P=0.003),and BATS was less originated from temporal lobe than ATLP (3.8％ (2/53) vs 23.8％ (10/42),x2=8.523,P=0.004).Conclusion Different from ATLP,the broad BATS are characterized by tonic proximal upper limb posturing,and have a higher predictive value on lateralization and localization of SOZ.
