Objective To determine the clinical efficacy of the combination of Aidi injection and chemotherapy in patients of advanced non-small-cell lung cancer (NSCLC). Methods One hundred and twenty three patients with stage ⅢB/Ⅳ NSCLC complying with diagnosis standard were eligible.Those patients were randomly divided into treatment group (63 patients) and control group (60 patients). Both of groups received NP regimens( NVB 25 mg/m2, ivgtt, d1,d8; DDP 25 mg/m2, ivgtt, d1-3, watering). In treatment group,patients received Aidi injection (50 ml, ivgtt, d1-10) combined with NP regimens. Then some indexes were observed, including outcomes in the overall response rates, adverse drug reaction, quality of life. Results In treatment group, outcomes in the overall response rates were 50.8 %, 5 patients were completely remitted(CR),27 patients were partly remitted(PR). In control group, outcomes in the overall response rates were 35.0 %(3 CR, 18 PR). Gastrointestinal reaction and bone marrow depression of treatment group was lower than control group. Quality of life of treatment group was higher than control group. The difference was significant between two groups (P＜0.05). Conclusion This Aidi injection plus chemotherapy combination is effective against NSCLC with mild toxicities and quality of life can be improved.

Objective To establish the rat overlap syndrome (OS) model of intermittent hypoxia (IH) combined with pulmonary emphysema and to explore its connection with hepatic oxidative stress, inflammatory status in the live and coagu?lation profile. Methods Male Wistar rats (n=60) were randomly divided into four groups:control group (A), IH group (B), pulmonary emphysema group (C) and OS group (D). The rat model of pulmonary emphysema was established by exposing rats in smoke for 16 weeks. From the 13th week, pre-programmed intermittent hypoxia/re-oxygenation (IH/ROX) exposure was given in the meantime of smoke exposure in OS group. Liver tissues were sectioned or triturated for pathological scoring or for detecting expression levels of superoxide dismutase (SOD), catalase (CAT) and malondialdehyde (MDA) respectively. Se?rum levels of coagulant/anticoagulant factors such as antithrombin (AT), fibrinogen (FIB), von Willebrand factor(vWF) and FactorⅧ(FⅧ) were also evaluated using biochemistry analysis. Results The levels of pathological scores and coagulant factors(FIB, FⅧ:C and vWF:Ag)were significantly higher in group D than those in group A, B and C. The values of SOD, CAT and AT were significantly lower in group D than those in other three groups. Serum levels of FIB, vWF:Ag, FⅧ:C and AT:A correlated with SOD(r equal to-0.905、-0.941、-0.946 and 0.817 respective,P<0.01). Conclusion In rat overlap syndrome when IH combined with pulmonary emphysema, hepatic inflammation and coagulability present mutual promotion effect and produce a more significant liver-derivative inflammatory and prothrombotic status.

Results ET in different group was(6 .53 ± 14 .96) ,(4 .40 ± 1 .15) ,(4 .20 ± 1 .20) ,(4 .09 ± 1 .31) ,(3 .70 ± 1 .46)EU/mL ,respec‐tively .There were no difference between each group .Conclusion ET examination suggests there is no difference between different type of intestinal obstruction in children and endotoxemia is not found in intestinal obstruction according to the results .

In order to investigate whether Laribacter hongkongensis could be detected in stool samples of Rattus norvegicus in the wild,Rattus norvegicus were trapped alive in an urban community of Guangzhou,China over a period of one year from June 2015 to May 2016,and their stool samples were examined for the presence of L.hongkongensis strains.Isolates were identified based on phenotypic characteristics and 16S rRNA sequence analysis,and were examined for their susceptibility to 19 antimicrobial agents.Further typing of the isolates was performed using multi-loci sequence typing (MLST) analysis.A total of 191 R.norvegicus were trapped alive.L.hongkongensis was identified and successfully isolated from two samples,representing a prevalence of 1.05 ％.Although the two isolates possessed similar phenotypic characteristics and have no base difference of 16S rRNA gene,they constituted two new distinct sequence types (STs),ST-163 and ST-164.This is the first report that L.hongkongensis can be detected in the intestinal tract of R.norvegicus.Results suggest that R.norvegicus could serve as carriers of L.hongkongensis and therefore could be another potential source of infection.

OBJECTIVETo confirm diagnosis of a special case with chief complaints of abdominal pain and dyskinesia of lower extremities.

METHODSThe clinical symptoms, signs, MRI, pathological findings and the results of blood test for microfilaria were analyzed.

RESULTSThe patient was a 6-year old girl who had abdominal pain for 10 days dyskinesia of lower extremities for 6 days accompanied by difficulty in urination and defecation. There was tenderness on T7-9 spinous process, sensory dullness below the umbilicus. Babinski's and Oppenheim's sign were bilaterally positive, and ankle clonus was positive. MRI showed space occupying change in the vertebral canal at T7-9 level. The mass of 2 cm x 1 cm x 1 cm size was removed by surgical operation and histopathological study showed obvious fibrous tissue proliferation accompanied by eosinophil, lymphocyte and neutrophil infiltration around a worm-like structure. Night time blood test performed at 23:00 confirmed the presence of microfilaria.

Objective To evaluate the early change of left ventricular (LV) systolic function in patients with type 2 diabetes mellitus(T2DM) by ultrasound speckle tracking imaging. Methods Ninety-five subjects were included:40 T2DM with normal LV ejection fraction (LVEF≥50% ,group A),20 T2DM with abnormal LVEF (LVEF<550 %) (group B), and 35 normal controls. Two-dimensional strain images were acquired from LV short-axis view. LV peak systolic global and segmental radial strain and circumferential strain at the levels of mitral annulus, papillary muscle and apex, and LV systolic global and segmental rotation at the levels of mitral annulus and apex and LV peak systolic global twist were assessed. Results In group A, compared with control group, LV peak systolic radial strain parameters were not significant difference (P >0.05), peak systolic circumferential strain of part segments, average peak strain of each plane and global strain were reduced (P <50.05～0.001) ,and LV peak systolic rotation of all apical segments, peak systolic global rotation at the levels of mitral annulus and apex,and peak systolic global twist were significantly increased (P <0.05～0.001). Compared with control group and group A,all LV systolic radial strain and circumferential strain parameters, LV systolic global and segmental rotation and peak systolic global twist in group B were significantly reduced (P <0.05 ～ 0.001). Conclusions Speckle tracking imaging could be used to evaluate the early change of LV torsional deformation and LV systolic function in T2DM.
