Objective To investigate the prevalence and clinical significance of different subtypes (IgG,IgM and IgA) of anticardiolipin antibodies (aCL) and anti-β2-glycoprotein Ⅰ antibodies (aβ 2GP1),as well as lupus anticoagulant (LA) in systemic lupus erythematosus (SLE).Methods IgG/IgM/IgA,IgG,IgM,IgA aCL and anti-β2GP1 were tested by enzyme-linked immunosorbent assay (ELISA) in 100 patients with SLE (42 patients were diagnosed as secondary antiphospholipid syndrome),44 healthy controls and 32 patients with other connective tissue diseases excluding SLE and antiphospholipid syndrome (APS).Meanwhile,LA was tested by modified Dilute Russell's viper venom time (dRVVT).The correlation between antiphospholipid antibodies and clinical manifestation was analyzed by Spearman correlation analysis.The postiverate of antiphospholipid antibodies in SLE patients,health controls and patients with other connective tissue diseases were compared by chi square test.The concentrations of antiphospholipid antibodies in different groups were compared using independent sample Kruskal Wallis test.The diagnostic efficacy of antiphospholipid antibodies in SLE patients was analyzed by crosstable using clinical diagnosis of APS as gold standard.P ＜ 0.05 was considered statistically significant.Results The prevalence of IgG aCL (x2 =15.031,P ＜ 0.001),IgA/G/M (x2 =11.678,P =0.003) and IgA (x2 =6.17,P =0.036) antiβ2GP1 were significantly higher in patients with SLE than in the other two groups.IgA/G/M (r =0.207,P=0.039),IgG (r=0.230,P=0.021) and IgA (r=0.217,P=0.030) aCL,IgA/G/M (r=0.218,P=0.029) and IgA (r =0.255,P =0.01) anti-β2GP1,as well as LA (r =0.233,P =0.02) were associated with thrombotic events.IgA/G/M anti-β2GP1 (r =0.22,P =0.029) and LA (r =0.254,P =0.011) were associated with pathological pregnancy.23.1％ (6/26) aCL positive SLE patients were IgM and/or IgA aCL positive.53.6％ (15/28) anti-β2GP1 positive SLE patients were IgM and/or IgA antiβ2GP1 positive.In SLE patients,the specificity and sensitivity of IgA/G/M aCL for APS were 98.3％ and 26.2％,respectively.The specificity and sensitivity of IgA/G/M anti-β2GP1 were 84.5％ and 40.5％,respectively.The specificity of at least two isotypes positive for APS (both aCL and anti-β2GP1 were 98.3％),was higher than IgG aCL (94.8％) or anti-β2GP1 (93.1％).The sensitivity of at least one isotype of aCL (47.6％) or anti-β2GP1 (42.9％) positive for APS were higher than IgG aCL (40.5％)and anti-β2GP1 (21.4％).Conclusions IgG and IgM aCL together would be better than IgA/G/M aCL for APS screening.IgA/G/M anti-β2GP1 would be better for APS screen due to higher sensitivity and strong association with thromboembolic events and pathologic pregnance.IgA aCL or anti-β2GP1 was associated with thromboembolic events.IgA aCL or anti-β2GP1 would be useful for APS diagnosis in IgG and IgM aCL or anti-β2GPl negative patients.

Abstract: Objective　By collecting and sorting the information of varicella cases reported in Liaoning Province from 2006 to 2021, the epidemiological characteristics were analyzed, and the monthly incidence data were predicted, so as to explore the prevention and control strategy of varicella disease in Liaoning Province. Methods　By collecting the characteristic information of varicella cases in Liaoning Province, epidemiological analysis was carried out on the regional, population, and temporal characteristics of varicella incidence. The monthly incidence data of varicella were fitted with Eviews software, seasonal ARIMA model was used for modeling, and models were selected according to SC and AIC. After modeling, the model was used to predict the incidence data in 2022. Results　The incidence rate of varicella in Liaoning Province has increased in recent years. The onset time was "bimodal distribution", with the main peak occurring from November to January of the next year and the secondary peak occurring from May to June. Since 2019, the onset age has shifted backward. From the original 0-<10 age group with the highest incidence rate, it shifted to the 10-<20 age group with the highest incidence rate. From 2006 to 2021, the incidence of varicella mainly concentrated in people aged 0 to <40 years old, and the incidence rate of the population over 40 years old showed a cliff-like decline. The incidence of chickenpox was higher in the central region of Liaoning Province, such as Shenyang, Dalian, Anshan and Panjin, and relatively low in Huludao, Jinzhou, Fuxin and Liaoyang. The distribution of the population was mainly students, followed by kindergartens and scattered children. ARIMA model of monthly incidence data was established by software as ARIMA (1, 0, 1) (1, 1, 1)12. Conclusions　The incidence rate of varicella in Liaoning Province has been rising in recent years. The incidence is obviously seasonal, and the age group of the affected population has moved backward. It is predicted that the incidence will continue to increase in 2022. The prevention and control of varicella should still be the current key work. In order to reduce the population incidence rate, two-dose vaccination strategies should be vigorously promoted the implementation of the, and the inclusion of varicella vaccine in the immunization program should be achieved as soon as possible.

Objective: To systemically review the safety and efficacy of Absorb bioresorbable vascular scaffold (Absorb BVS) versus cobalt chromium-everolimus eluting stent (CoCr-EES) for treating the patients with coronary artery disease (CAD) by percutaneous coronary intervention (PCI).
Methods: We searched relevant literatures in PubMed, Embase, Cochrane Library, CNKI and Wanfang database from 2008-01 to 2015-10, meanwhile, collected published data and randomized controlled trials from meeting abstracts and websites to compare Absorb BVS and CoCr-EES for treating CAD patients. The quality of literatures were assessed and extracted by modiifed Jadad score, Meta-analysis was conducted by STATA 12.0 soft ware.
Results: There were 4 eligible trials with 3,389 patients were enrolled. Absorb BVS group, n=2,164 and CoCr-EES group, n=1,225. During the mean of 1.1 years follow-up period, the following incidences were similar between 2 groups:target lesion failure (OR=1.29, 95%CI 0.95-1.74, P=0.10), all cause death (OR=1.31, 95%CI 0.60-2.87, P=0.50), cardiac death (OR=1.38, 95%CI 0.45-4.24, P=0.57), myocardial infarction (OR=1.30, 95%CI 0.93-1.80, P=0.12), deifnite or probable stent thrombosis (OR=2.08, 95%CI 0.95-4.54, P=0.07), re-vascularization (OR=1.03, 95%CI 0.80-1.33, P=0.81), target lesion re-vascularization (OR=1.06, 95%CI 0.67-1.66, P=0.81) and the patient-oriented composite endpoint (OR=0.95, 95%CI 0.66-1.35, P=0.76).
Conclusion: Absorb BVS and CoCr-EES had the similar safety and efifcacy for treating the low and moderate risk CAD patients who had angina, ischemia while without symptoms. The longer period of follow-up study and larger randomized, controlled clinical trials were needed for Absorb BVS application in clinical practice.

OBJECTIVETo evaluate the impact of nicotine- and tar-free cigarette smoke extract (fCSE) on the serum testosterone (T) level and erectile function of male rats.

METHODSWe randomized 30 male SD rats to three groups of equal number to receive subcutaneous injection of PBS (1.0 ml / 300 g body weight per day), fCSE (1.0 ml/300 g body weight per day), and reduced glutathione hormone (GSH, 200 mg per kg body weight per day) in addition to fCSE (fCSE + GSH), respectively, all for 8 weeks. Then we evaluated the erectile function of the rats by measuring the maximal intracavernous pressure (MICP), mean arterial pressure (MAP), ICP/MAP ratio, time of stimulation to MICP (Tmax), and cavernosal filling fate (CFR). We determined the serum T level, the activities of superoxide dismutase (SOD) , malondialdehyde (MDA), and nitric oxide synthase (NOS) in the cavernosal tissue, and also observed the morphological changes of the corpus cavernosum.

RESULTSCompared with the controls, the rats of the fCSE group showed obvious decreases in the levels of serum T ([5.37 ± 1.43] vs [3.22 ± 1.11] μg/L), NOS ([2.90 ± 0.27] vs [1.67 ± 0.18] U/mg) , and SOD ([18.41 ± 1.09] vs [13.36 ± 1.18] U/mg prot) and erectile function-related indexes MICP ([85.92 ± 6.36] vs [58.99 ± 10.76] mmHg), MICP/MAP (0.86 ± 0.09 vs [0.56 ± 0.08]), and CFR (2.14 ± 0.44 vs 0.89 ± 0.44), but markedly increased Tmax ([29.90 ± 5.78] vs [42.90 ± 8.56]s), with a positive correlation between the serum T level and CFR (r = 0. 364, P < 0.05). Masson staining revealed a lower ratio of the corpus cavernosum smooth muscle tissue to collagen fiber in the fCSE group (0.27 ± 0.04) than in the control (0.98 ± 0.12). Compared with the fCSE group, the fCSE + GSH group exhibited significantly improved MICP ([58.99 ± 10.76 ] vs [77.95 ± 7.71] mmHg), MICP/MAP (0.56 ± 0.08 vs 0.77 ± 0.09), and CFR (0.89 ± 0.44] vs 1.76 ± 0.42) and shortened Tmax ([42.90 ± 8.56 ] vs [32.10 ± 5.84 ] s). The ratio of the corpus cavernosum smooth muscle tissue to collagen fiber was higher in the fCSE + GSH than in the fCSE group (0.77 ± 0.09 vs 0.27 ± 0.04) but still lower than in the control (0.98 ± 0.12).

CONCLUSIONNicotine- and tar-free cigarette smoke extract reduces the serum T level and erectile function of rats, which is related to oxidative stress. Antioxidant therapy can improve erectile function but has a limited value for morphological protection of the penile tissue.

Objective: To systematically review the safety and efifciency for dual antiplatelet therapy (DAPT) ≤ 6 months and DAPT ≥ 12 months in patients after drug eluting stent (DES) implantation. Methods: We collected the data for randomized clinical trials for DAPT ≤ 6 months and DAPT ≥ 12 months in patients after DES implantation up to 2015-01 by searching the literatures of PubMed, EMBASE, Cochrane Library, Scopus and Chinese literature database, and meanwhile collected the relevant reporting cases from both domestic and international cardiovascular conferences for this study. There were 2 investigators independently conducted the literature screening, data extraction and quality evaluation, Meta analysis was performed with STATA 12.0 software. Results: A total of 15,378 patients from 7 eligible studies were enrolled and the patients were divided into 2 groups: DAPT ≤ 6 months group,n=7672 and DAPT ≥ 12 months group,n=7706. Meta analysis indicated that DAPT ≤ 6 months could effectively reduce the major bleeding (OR=0.58, 95% CI 0.37-0.91,P=0.017). While the other incidences between 2 groups were similar as all cause death (OR=0.90, 95% CI 0.73-1.11,P=0.314), cardiac death (OR=0.93, 95% CI 0.70-1.24,P=0.617), myocardial infarction (OR=1.13, 95% CI 0.91-1.41,P=0.275), in stent thrombosis (OR=1.21, 95% CI 0.79-1.85,P=0.382) and cerebrovascular accidents (OR=1.00, 95% CI 0.66-1.51,P=1.000). Conclusion: The incidence rates of cardiovascular and cerebrovascular events are similar in patients with DAPT ≤ 6 months and DAPT ≥ 12 months after DES implantation. DAPT ≤ 6 month had the lower risk of bleeding, which is rather suitable for the patients received new generation of DES, with higher risk of bleeding, lower risk of thrombosis and with poor compliance to medication; however, the large and randomized clinical trials are needed to make ifnal conclusion.
