Objective To investigate the factors related to the occurrence of in-stent restenosis (ISR) after percutaneous coronary drug-eluting stent (DES) implantation. Methods A total of 258 consecutive patients with coronary angiography confirmed ISR that occurred at least one year after coronary sirolimus-eluting stent implantation, who were encountered at the Affiliated Ruijin Hospital of Shanghai Jiaotong University during the period from September 2010 to September 2014 , were collected as ISR group; and other 260 age-and sex-matched patients with no ISR at least one year after coronary sirolimus-eluting stent implantation, who were encountered at the same hospital and during the same period, were collected as the control group. The clinical characteristics, biochemical measurements, postoperative medications, left ventricular ejection fraction (LVEF), and coronary interventional features were determined;using multivariate logistic regression analysis the independent factors related to the occurrence of ISR were evaluated. Results Compared to the control group, in ISR group the history of previous myocardial infarction , presence of diabetes mellitus and cigarette smokers were more often seen; serum levels of high-sensitivity C-reactive protein(hs-CRP), glycosylated hemoglobin, low-density lipoprotein cholesterol (LDL-C)and apoliprotein B in ISR group were significantly increased (P<0.05), while LVEF was decreased (P<0.05). Although the number of coronary lesions and the site of stent implantation were quite similar in both groups , the stents used in ISR group were smaller and longer (P<0.05), and bifurcation stenting procedure was more employed in ISR group (P<0.05). Multivariate Logistic regression analysis revealed that the history of previous myocardial infarction, diabetes, cigarette smoking, elevated serum hs-CRP and LDL-C levels, and longer stent length were independent risk factors for the occurrence of ISR, whereas stent diameter and LVEF bore a negative correlation with ISR. Conclusion The occurrence of ISR after coronary sirolimus-eluting stent implantation is related to multiple clinical and coronary angiographic and interventional factors. Effective control of risk factors of coronary heart disease and improvement of left ventricular function play an important role in preventing ISR, especially for the patients who has small vessel disease, and in whom longer stents are employed and bifurcation stenting procedure is carried out.

Objective To study the effects of verussurinine (VSRN), an alkaloid isolated from Veratrum nigrum var. ussuriense alkaloids (VnA), against thrombosis and its platelet aggregation inhibitory activity in rats in order to find out whether VSRN is the antithrombotic active ingredient of VnA. Methods The electrically induced rat carotid artery thrombosis and stasis-induced rat inferior vena cava thrombosis models were used to evaluate the anti-arterial and anti-venous thrombosis effect of VSRN, respectively. Borns turbidimetric method was used to examine the in vivo and in vitro anti-platelet effect so as to investigate the antiplatelet aggregation of VSRN. Results In comparison with saline, VSRN in five different doses (1.25—20.00 ?g/kg) showed significantly and dose-dependently prolonged occlusion time (OT) of carotid artery injured by electrical stimulation and reduced thrombus dry weight of inferior vena cava ligated for 4 h to cause stasis. Platelet aggregation was found to be inhibited by VSRN in the doses of 1.25—5.00 ?g/kg and at the concentration of 6.25—50 ?g/L in both in vivo and in vitro test. Conclusion VSRN has powerful arteriovenous antithrombosis and antiplatelet aggregation of rats. The antithrombotic effect of VSRN is related to its platelet aggregation inhibitory activity. The above findings indicate that VSRN is an antithrombotic active ingredient of VnA.

OBJECTIVETo investigate the guidance role of preoperative nutritional risk screening in perioperative nutrition support for colorectal cancer patients in order to provide evidence for the rational clinical application of nutrition support.
METHODSNutritional risk screening was carried out in 290 hospitalized colorectal cancer patients from The Fourth People's Hospital of Wuxi City, Tongji Hospital of Tongji University and The Second Hospital of Soochow University with the nutritional risk screening(NSR) 2002 score summary table. Postoperative bowel function recovery and associated nutritional indices were compared between patients who received preoperative nutrition support according to the risk screening results and those who did not.
RESULTSAmong 110 patients at nutritional risk, 65 received perioperative nutrition support and had faster recovery of intestinal function [time to first flatus (2.3±0.5) d vs. (3.3±0.5) d, time to first defecation (3.5±0.5) d vs. (4.6±0.6) d, semi-fluid intake (10.1±1.2) d vs. (12.4±2.2) d], shorter postoperative stay [(15.7±1.1) d vs. (18.8±1.4) d], and higher albumin, prealbumin and transferrin [(33.2±4.5) g/L vs. (26.0±4.0) g/L, (0.28±0.05) g/L vs. (0.16±0.04) g/L, (1.92±0.33) g/L vs. (1.75±0.45) g/L] at 7-day postoperatively (all P<0.05) as compared to those without perioperative nutrition support(n=45). While among 180 cases without nutritional risk, there were no significant differences in the above indices between patients who received preoperative nutrition support and those who did not (all P>0.05).
CONCLUSIONIt is important to evaluate the nutritional risk in hospitalized patients with colorectal cancer, and to carry out nutrition support actively for those at nutritional risk.

They were divided into gefitinib treatment group (30 cases, treated with gefitinib) and combined treatment group (30 cases, treated with pemetrexed combined with cisplatin) by random number table. The anti-tumor efficacy, levels of tumor markers [serum carcinoembryonic antigen (CEA), cytokeratin 19 fragment antigen (CYFRA21-1) and neuron-specific enolase (NSE)] before and after treatment, adverse reactions and 6-month overall survival (OS) rate were compared between the two groups.Results:The clinical control rate of gefitinib treatment group was higher than that of combined treatment group [76.7% (23/30) vs. 50.0% (15/30), χ2 = 4.593, P = 0.032]. There was no significant difference in the levels of CEA, CYFRA21-1 and NSE between the two groups before treatment (all P > 0.05). The levels of CEA, CYFRA21-1 and NSE after treatment in gefitinib treatment group were (902±41) μg/L, (3.1±0.4) ng/ml and (17.7±2.3) ng/ml. The levels of CEA, CYFRA21-1 and NSE after treatment in combined treatment group were (999±51) μg/L, (4.0±0.5) ng/ml and (19.4±3.1) ng/ml. The levels of CEA, CYFRA21-1 and NSE after treatment in gefitinib treatment group were lower than those in combined treatment group ( t = 7.441, P < 0.01; t = 7.459, P < 0.01; t = 2.486, P = 0.016).The levels of CEA, CYFRA21-1 and NSE after treatment in the two groups were all lower than those before treatment, and the differences were statistically significant (all P < 0.05). There was no significant difference in the incidence of rash, thrombocytopenia, digestive tract reaction, and proteinuria between the two groups [26.7% (8/30) vs. 23.3% (7/30), χ2 = 0.089, P = 0.766; 16.7% (5/30) vs. 13.3% (4/30), χ2 = 0.131, P = 0.718); 30.0% (9/30) vs. 26.7% (8/30), χ2 = 0.082, P = 0.774; 10.0% (3/30) vs. 13.3% (4/30), χ2 = 0.162, P = 0.688]. After 6 months of treatment, the OS rate in gefitinib treatment group was 93.3%, and that in combined treatment group was 83.3%, and there was no statistical difference between the two groups ( χ2 = 1.456, χ2 = 0.228). Conclusion:Gefitinib treatment for EGFR-positive advanced NSCLC patients can enhance the anti-tumor efficacy, reduce the content of tumor markers, and has good safety.

Objective:To explore the clinical curative effect of foot-ankle balance massage combined with herbal fumigation on acute ankle sprain.Methods:According to random number table method, 62 patients with acute ankle sprain meeting the inclusion criteria in the hospital were divided into control group and observation group between January 2018 and January 2021, 31 in each group. The control group was treated with foot-ankle balance massage, while the observation group added herbal fumigation treatment on the basis of the control group treatment. Both were treated for 7 days. The pain degree was evaluated by Visual Analogue Scale (VAS). The pain sites of ankle joint were evaluated by Kofoed ankle scale. The recovery of ankle and foot function was evaluated by American Orthopaedic Foot and Ankle Society (AOFAS). The levels of plasma substance P, neuropeptide, nerve growth factor (NGF), IL-1β, IL-6 and hs-CRP were detected by enzyme-linked immunosorbent assay. The clinical curative effect was assessed.Results:The differences in total response rate between observation group and control group were statistically significant [96.8% (30/31) vs. 77.4% (24/31)] ( χ 2=5.17, P=0.023). At 1st day, 3rd day and 7th day after treatment, VAS scores in observation group were significantly lower than those in the control group ( t=4.86, 5.19, 3.86, P<0.01), Kofoed scores were significantly higher than those in the control group ( t=2.03, 2.58, 2.46, P<0.05), and AOFAS pain scores were significantly higher than those in the control group ( t=2.61, 2.47, 4.90, P<0.05). After treatment, levels of substance P [(2.94±0.91) mg/L vs. (3.69±0.94) mg/L, t=3.19], neuropeptide [(141.06±16.31) ng/L vs. (165.22±17.63) ng/L, t=3.16] and NGF [(43.65±10.15) ng/L vs. (52.26±10.20) ng/L, t=3.33] in observation group were significantly lower than those in the control group ( P<0.01), and levels of IL-1β, IL-6 and hs-CRP were significantly lower than those in the control group ( t=2.60, 2.64, 2.42, P<0.05). Conclusion:The foot-ankle balance massage combined with herbal fumigation can quickly relieve pain, increase levels of pain substances, reduce levels of inflammatory cytokines and improve curative effect in patients with acute ankle sprains.
