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 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.

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.

Objective: To evaluate the sensitivity and specificity of exhaled nitric oxide in the diagnosis and therapy of bronchial asthma. Methods: From January 2016 to December 2017, 87 patients diagnosed with bronchial asthma in Luoyang Central Hospital Affiliated to Zhengzhou University were selected as asthma group , and 40 healthy people were selected as healthy control group at the same term.The levels of FeNO, FEV₁/pred, peripheral blood EOS count, ACT score, percentage of sputum EOS were measured. Results: The positive rate of FeNO was 56.3%(49/87) in the asthma group, which in the healthy control group was 5.0%(2/47). The fractional exhaled nitric oxide level of reexamined patients before treatment [(70.9±53.6)ppb] was higher than that after treatment[(12.2±8.7)ppb], and the difference was statistically significant(t=4.323, P=0.001). The fractional exhaled nitric oxide level in the asthma group [(42.4±42.5)ppb] was higher than that in the healthy control group [(9.4±5.8)ppb], and the difference between the two groups was statistically significant(t=2.871, P=0.001). The fractional exhaled nitric oxide level was positively correlated with peripheral blood EOS count (r=0.376, P=0.000) and ACT score (r=0.361, P=0.001), but had no correlation with FEV₁/pred (r=-0.111, P=0.306) and sputum EOS (r=-0.036, P=0.805). Conclusion The measurement of fractional exhaled nitric oxide levels has an important clinical significance in the diagnosis of bronchial asthma.And it has a guiding significance for the evaluation of the therapeutic effect of bronchial asthma.

Objective To investigate the occurrence and prevention measures of long term complications in long term survival recipients after liver transplantation.Methods In the recipients undergoing liver transplantation from Sept. 2003 to Dec. 2004,by Nov. 30,2011,there were 62 cases with the survival time more than seven years.The clinical data and follow up examination results of these 62 cases were retrospectively,including weight,blood pressure,blood sugar,blood lipids,and liver and kidney functions. The incidence of long-term complications was statistically tested.Results Postoperative metabolic complications including overweight or obese occurred in 21 cases (33.9％), new onset diabetes in18 patients (29％), hyperlipidemia in 17 cases (27.4％),hypertension in 9 cases ( 14.5 ％ ),and kidney dysfunction in 12 patients ( 19.4％ ).The incidence of diabetes and hyperlipidemia in the patients with overweight and diabetes (respectively 52.4％ and 42.9％) was significantly higher than in the normal weight group (respectively 17.1 ％ and 19.5 ％)(P＜0.05).In 58 recipients with primary diseases of hepatitis B-related liver diseases,one case had hepatitis B virus reinfection. In 17 recipients with primary disease of primary liver cancer,tumor recurrence occurred in 2 cases.During the follow up period,4 patients received liver re-transplantation due to hepatic artery stenosis (1 case) or biliary complications-induced loss of the transplanted liver function (3 cases).Conclusion The major complications of the long term survival recipients after liver transplantation are metabolic complications and primary disease relapse. Postoperative long-term follow up and monitoring of recipients is recommended to prevent and treat a variety of long-term complications.
