Objective To study the effect of interventional treatment of iliac and femoral vein stenosis concomitant with deep venous thrombosis. Method Fifty-three patients were divided into 5 groups. In group A after placing into inferior vena cava a filter,11 patients adopted Amplatz Trombectomy Device for thrombolysis or ORSIS thrombolysis and persistent thrombolysis through popliteal vein. In group B thrombus was taken out through guiding catheter and then persistent thrombolysis through popliteal vein after placing into inferior vena cava filters in 9 cases. In group C 13 patients adopted persistent thrombolysis through femoral arteries. In group D 8 patients received persistent thrombolysis through popliteal vein. In group E persistent thrombolysis through foot veins was carried out in 12 patients. Seventeen patients received implanted stents and balloon-expansion in iliac and femoral veins. Results Symptoms disappeared in 26 patients(49.0%), significantly improved in 21 patients (39.6%), improved in 3 patients (5.7%), did not improve in 3 patients (5.7%), respectively. The repatency of iliac and femoral vein was achieved in more than 80% of the 17 patients. Complications developed in 3 cases in the course of thrombolysis. Conclusion The effect of mechanical removal of thrombus, persistent thrombolysis through catheter and transluminal angioplasty is safe and satisfactory.

Integration of "5+3" training mode is to accelerate the construction of standardization of clinical medical personnel training system,and the establishment of the new training mode.The training goal is to make the students become the high-level clinicians with the ability of clinical thinking and clinical practice,and scientific research and teaching,who can independently and pro-fessionally prevent and treat the related common disease.Therefore,guided by the general training goal of our students,we designed and practiced a teaching mode centered on "immune disease mechanism analysis" in the teaching of medical immunology,aiming at improving students'ability of clinical thinking,self learning and team coorperation.

AIM: To investigate therapeutic efficiency of amniotic extraction on dry eye in rabbit model induced by topical benzalkonium chloride (BAC).
METHODS: Totally 26 rabbits (26 right eyes) with dry eye model were studied and divided into two groups:group A (control group with PBS eye drops, n = 13) and group B ( amniotic extraction group, n = 13). Another two rabbits were chosen as normal control. The SchirmerⅠ tests ( S Ⅰ t) and corneal fluorescein staining ( FL) were made, and the tear total protein content, amylase activity, lactoferrin, lysozyme contents, goblet cell density were performed in two groups before treatment and 1, 2, 4 and 8 wk after treatment.
RESULTS: There were significant differences in SIT, FL scores, lysozyme activity and goblet cell density among different groups at different time points (P<0. 05). But, there was no significant differences in SⅠt, FL scores, lysozyme activity and goblet cell density between two groups before treatment (P>0. 05). After 8wks' treatment with PBS, the mean differences of the group A showed great changes in SⅠt, lysozyme and goblet cell density compared with those before treatment ( P < 0. 05); but there was no significant differences in FL scores compared with those before treatment (P>0. 05). As for group B, 8wks after treatment, there were statistical changes in SⅠt, FL, lysozyme (P<0. 05); but there was no significant differences in goblet cell density compared with those before treatment ( P > 0. 05). It was evident that statistical differences were observed in S Ⅰ t, FL scores, lysozyme activity and goblet cell density between two groups at each time point (P<0. 05). However, there were no significant differences in total protein, lactoferrin, amylase activity at different time points (P>0. 05). Meanwhile there was no significant differences in total protein, lactoferrin, amylase activity between two groups before treatment ( P > 0. 05 ). But there were significant differences in total protein, lactoferrin, amylase activity between two groups after 4 and 8 wks'treatment (P<0. 05).
CONCLUSION: Amniotic extraction has significant therapeutic effect on the dry eye in rabbit model.

As a member of G protein coupled-receptors superfamily, free fatty acid receptor 1 (FFAR1), is also known as GPR40, has been shown to regulate numerous pathophysiological processes in a variety of tissues and organs. The activated FFAR1 has a variety of biological functions. For instance, it can not only regulate metabolism of fatty acids and glucose, but also play an important role in immune inflammatory response, it may be a potential drug target for the treatment of various chronic inflammatory diseases. In this review, we focus on the recent researches of FFAR1's action in the regulation of pathophysiological processes, its molecular mechanism and new agonists development. At the same time, this review will take the discovery of series FFAR1 agonists as examples, and display the applied prospects of FFAR1.

OBJECTIVETo study the expression of Aurora-B in human glioma tissue and its significance.

METHODSThe total RNA was extracted from 41 human glioma tissues and 11 normal brain tissues by Trizol reagent. After reverse transcription of the total RNA into cDNAs, Aurora-B mRNA expressions in these samples were detected by quantitative real-time PCR. The protein expression in these samples was detected using immunohistochemical staining.

RESULTSAurora-B mRNA and protein expressions were significantly increased in glioma tissues as compared with those in normal brain tissues.

CONCLUSIONAurora-B mRNA and protein show markedly higher expressions in glioma tissue, suggesting that Aurora-B may be one of the malignant biomarkers in the pathogenesis and progression of human glioma.

OBJECTIVETo explore the effects of overexpression of human tissue inhibitors of metalloproteinase-1 (hTIMP-1) on proliferation, invasion, metastasis, angiogenesis, and apoptosis in human hepatocellular carcinoma (HCC) cells in vitro and in vivo.

METHODSRecombinant adenoviral vector containing hTIMP-1 (AdhTIMP-1) was constructed previously. HepG2 cells were infected by AdhTIMP-1 and the changes of cell proliferation and invasion were detected in vitro. The anticancer activity of AdhTIMP-1 was evaluated in BAL B/c mice bearing HCC. Tumor volume and pulmonary metastases were observed. The mechanisms underlying the antitumor effect in vivo were investigated based on detection of microvessel density and apoptosis in tumor tissues.

RESULTSThe resultant AdhTIMP-1 was successfully constructed and the expression of hTIMP-1 was detected by Western blot and RT-PCR. AdTIMP-1 could effectively infect HepG2 cells and significantly inhibit the proliferative activity and invasive ability of the tumor cells. Compared with the controls, pre-infection of HepG2 cells by AdhTIMP-1 resulted in a significant inhibition of tumor formation by 75. 8%. A single local injection of AdhTIMP-1 into pre-established tumors significantly reduced the tumor growth rate by 45.4%, tumor-associated angiogenesis index by 47.8%, lung metastases by 70.4%, and showed a 3-fold increase of apoptotic tumor cells.

CONCLUSIONOur data indicated that AdhTIMP-1 can significantly attenuate tumor proliferation and invasion, reduce metastasis, inhibit angiogenesis, and induce apoptosis in HCC-bearing mice and may pave the way for further liver cancer gene therapy.

OBJECTIVETo investigate the value of fractional nitric oxide concentration in exhaled breath (FeNO) in assessing the level of asthma control in children.

METHODSA total of 226 asthmatic children were divided into controlled asthma (n= 86), partially controlled asthma (n=63), and uncontrolled asthma groups (n=77). Ninety healthy children were enrolled as controls. FeNO was measured for both asthmatic and healthy children using the Swedish-designed NIOX system.

RESULTSThe control group had an FeNO of 14±6 ppb, the controlled asthma group had an FeNO of 29±26 ppb, the partially controlled asthma group had an FeNO of 32±30 ppb, and the uncontrolled asthma group had an FeNO of 40±32 ppb. The three asthma groups showed significantly higher FeNO than the control group (P<0.05). The uncontrolled asthma group showed significantly higher FeNO than the controlled asthma group (P<0.05), but there were no significant differences in FeNO between the partially controlled and uncontrolled asthma groups and between the partially controlled and controlled asthma groups (P>0.05).

CONCLUSIONSAsthmatic children have significantly higher FeNO than healthy children, and FeNO is correlated with the level of asthma control.

Objective To investigate the value of permeability surface (PS) in predicting hemorrhagic transformation (HT) in acute ischernic stroke (AIS) using CT peffusion (CTP).Methods The study included 31 consecutive patients who presented symptoms suggestive of an AIS for 3-9 h. All patients underwent CT examination (noncontrast CT,CTP).HT was determined by follow-up CT images.According to presence of HT,the AIS was divided into HT group (PSHT,11 patients) and non-HT group(PSNo-HT,20 patients).PS,cerebral blood flow (CBF),cerebral blood volume (CBV) and mean transit time (MTT) on both sides of brains were measured.The relative PS(rPS),relative CBF (rCBF),relative CBV(rCBV) and relative MTT(rMTT) were obtained by calculating the ratio of the values of bilateral regions.The rPS between PSHT and PSNo-HT was compared with an exact Wilcoxon signed-rank test. The rCBF,rCBV,rMTT and the PS of the ischemic side between PSHr and PSNo-HT were compared with independent-sample t test.Meanwhile,Spearman rank correlation analysis was conducted to analyze the relationship between the CTP parameters and HT.ResultsThe PS value of ischemic side was (1.61±0.77) ml · min - 1 · 100 g-1 for the PSHT group,and the value was (0.91 ± 0.49) ml · min - 1 · 100 g- 1 for the PSNo-HT group.For the PSHT group,rPS,rCBF,rCBV,rMTT were 2.76 ±0.78,0.32 ±0.18,0.66 ±0.31,2.67 ±0.71,and for the PSNo-HT group,rPS,rCBF,rCBV,rMTT were 1.35 ±0.19,0.50±0.21,0.91 ±0.28,2.62 ± 1.31.Compared with PSNo-HT,PSHT had higher rPS and PS value,and there were significant statistical differences (U =0.000,t =3.070,P ＜0.01).But rCBF and rCBV values were lower in the PSHT group compared to the PSNo-HT group,and there were significant statistical differences (trCsF =2.343,trCBV =2.210,P ＜ 0.05).There was no significant statistical difference in rMTT between the two groups(t =0.118,P ＞ 0.05).Significant positive correlations were detected between the rPS and PS with HT(r=0.496,0.821,P ＜0.01).ConclusionsThe value of rPS is helpful in predicting HT in AIS.And it can be used as a predictor in determining clinical personalized treatment and thus reduce the incidence of adverse events.
