Objective To evaluate the short-term effect of early treatment with clopidogrel before elective coronary stenting in patients with NSTE-ACS,compared with treatment with clopidogrel at the time of the procedure. Methods Patients with NSTE-ACS undergoing elective coronary stenting were randomly divided into two groups: early treatment group (n=272) and control group (n=265). Patients in the early treatment group were given clopidogrel immediately since hospitalization (300 mg loading dose, then 75 mg once daily); while in the control group, patients were given clopidogrel (300 mg) after coronary angiography followed by 75 mg per day after PCI. The composite endpoints were death, recurrent angina pectoris, instent thrombosis, myocardial infarction and urgent target vessel revascularization within 30 days after coronary stenting. Results Differences in baseline characteristics among patients between the two groups were negligible. There were no significant difference in the target vessel lesions requiring stenting between the 2 groups. Compared with the control group, early administration of clopidogrel showed a lower rate of death, myocardial infarction, refractory ischaemia, instent thrombosis and revascularization within 30 days of PCI. Conclusion Compared with administration of clopidogrel at the time of coronary stenting, pre-treatment with clopidogrel in patients with NSTE-ACS could significantly reduce the odds of adverse cardiovascular event and improve clinical outcomes within 30 days of PCI.

Malaria is a significant global infectious disease that once wreaked havoc in China as well. In recent years, the global malaria control situation has stagnated, and China is also facing a huge threat of imported malaria. So, effective malaria vaccines are urgently needed as a supplementary strategy to the existing prevention and control measures. Compared to vaccines targeting the erythrocytic stage and those designed to block transmission, vaccines aimed at preventing infection during the pre-erythrocytic stage have attracted more attention and have made a series of progress in recent years. At present, the only two malaria vaccines recommended by the World Health Organization (WHO) are pre-erythrocytic vaccines. In this paper, the current situation and trend of pre-erythrocytic malaria vaccine research and development are reviewed, intending to provide a reference for the research, development, and application of malaria vaccines in the future.

Objective To study the clinical efficacy of acupuncture combined with medication plus joint mobilization in the treatment of lumbar intervertebral disc protrusion accompanied with secondary lumbar spinal stenosis.MethodsTotally 66 cases of lumbar intervertebral disc protrusion accompanied with secondary lumbar spinal stenosis were collected randomly and divided into treatment group (34 cases) and control group (32 cases). The control group was given treatment of simple acupuncture and TCM medication, while the treatment group was given joint mobilization treatment besides acupuncture and TCM medication. Functions of lumbar vertebra were evaluated by ODI scale and the degrees of pain were evaluated by VAS. The clinical efficacy in the two groups was compared. Results ODI in both groups were significantly improved after treatment compared with that before treatment. However, the changing range of the ODI of the treatment group was more significant than that in control group (P<0.01). After treatment, VAS scores were relieved (P<0.05) in both groups, and treatment group was more significant than that in control group (P<0.05). The total clinical efficacy was 97.06% (33/34) in the treatment group, and 84.38% (27/32) in the control group, with statistical significance (P<0.05).Conclusion Acupuncture combined with medication plus joint mobilization in the treatment of lumbar intervertebral disc protrusion accompanied with secondary lumbar spinal stenosis has good efficacy.

Objective To evaluate the diagnostic accuracy of Streptocuccus pneumoniae urinary antigen test (SpUAT) in patients with community acquired Streptocuccus pneumoniae pneumoniae (SPP). Methods The clinical studies relating SpUAT diagnostic accuracy for community acquired Streptocuccus pneumoniae infection were searched via computer and manual screening of Chinese databases including China National Knowledge Internet (CNKI), China Biology Medicine disc, China Technical Journal Full-text Database, and Wanfang Database as well as English databases such as PubMed, EBSCO, Elsevier Science, Ovid Technologies, and Springer. Data were extracted according to appropriate inclusion and exclusion criteria and analyzed with Meta-disc 1.4 and Stata 12.0 software. Pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio as well as diagnostic odds ratio (DOR) were calculated, and summary receiver operating characteristic curve (SROC) was plotted and area under SROC (AUC) was calculated to analyze the diagnostic accuracy of SpUAT for adult community acquired SPP. Results A total of 15 studies enrolling 6 866 patients were included, all of which with a quality assessment of diagnostic accuracy studies (QUADAS) score not lower than 10, indicating a high study quality. Random effect model was applied owing to non-threshold effect associated heterogeneity. It was shown by Meta analysis that compared with routine pathogen diagnosis (hemoculture, sputum smears, sputum culture and trachea and bronchus attractive culture), the pooled sensitivity, pooled specificity, pooled positive likelihood ratio, and pooled negative likelihood ratio was 73% [95% confidence interval (95%CI) = 71%-76%,] 91% (95%CI = 90%-92%), 6.97 (95%CI = 4.13-11.77), and 0.30 (95%CI = 0.26-0.34), respectively, pooled DOR was 24.34 (95%CI = 13.14-45.11), and AUC of SROC was 0.8051±0.0362. It was indicated by heterogeneity test that experiment design (prospective or retrospective), sample sizes (lower than 200 or higher than or equal to 200), reference test (fewer than 3 or more than or equal to 3 test methods), or literature language (Hispanic or non-Hispanic) had no effect on study heterogeneity, indicating certain other unknown factors may be involved. Funnel plot suggested that 15 involved studies uniformly distributed along the two sides of regression line, indicating no publication bias. Conclusions The use of SpUAT for the diagnosis of adult community acquired SPP has a moderate sensitivity and high specificity. Although the overall accuracy of SpUAT diagnosis is relatively high, there is significant heterogeneity among the studies, so more high-quality studies are needed.

Objective To compare the efficacy of ozone injection plus electrothermal acupuncture versus oral glucosamine and nimesulide in treating knee osteoarthritis and investigate the effects of the two treatments on the WOMAC total score and the pain, stiffness and physical function scores.Method Eighty patients with knee osteoarthritis were randomly allocated to combination and Western medicine groups, 40 cases each. The combination group received a combined treatment with intra-articular ozone injection and electrothermal acupuncture and the Western medicine group took glucosamine hydrochloride and nimesulide sustained-release tablets. The WOMAC score was recorded in the patients before and after treatment. The therapeutic effects were evaluated using the WOMAC score. Result The control and marked efficacy rate of ozone injection plus electrothermal acupuncture for knee osteoarthritis was higher than that of Western medicine. The WOMAC score decreased in both groups after treatment (P<0.05) but decreased more in the combination group than in the Western medicine group (P<0.05). There were no significant post-treatment differences in the pain and stiffness scores between the combination and Western medicine groups (P>0.05). The physicalfunction score decreased more in the combination group than in the Western medicine group (P<0.05).Conclusion Ozone injection plus electrothermal acupuncture is more effective than Western medicine in treating knee osteoarthritis. It is more effective in improving knee function but not in relieving the pain and joint stiffness in comparison with Western medicine.

Methods:
College students were sampled from full-time colleges and universities in Guiyang City using a multi-stage stratified cluster sampling method from March to May in 2022. Students' knowledge, attitude and practice on e-cigarette use were collected using a questionnaire designed based on the 2019 China National Youth Tobacco Survey Questionnaire, and factors affecting the attempt to use e-cigarette were identified using a multivariable logistic regression model.
Results :
Totally 2 800 questionnaires were recovered, including 2 694 valid questionnaires, with an effective recovery rate of 96.21%. The respondents included 687 males (25.50%) and 2 007 females (74.50%). The total score of knowledge on e-cigarette use was (2.95±1.02) points, and there were low proportions of knowing that e-cigarettes contained hazardous substances, including nicotine and tar (59.06%) and knowing that e-cigarette use may cause diseases (53.27%). The total score of attitudes towards e-cigarette use was (5.09±2.36) points, and 93.50% of respondents did not use e-cigarettes given by companions. There were 132 students with attempts to use e-cigarettes (4.90%), and there were 29 current e-cigarette users (1.08%). Multivariable logistic regression analysis identified age of 20 years and lower (OR=0.438, 95%CI: 0.267-0.719), living in rural areas (OR=0.458, 95%CI: 0.264-0.794), thinking that e-cigarettes are addictive (OR=0.449, 95%CI: 0.217-0.928), and thinking that e-cigarette smoking is harmful (OR=0.263, 95%CI: 0.131-0.527) as factors protecting from e-cigarette use, and monthly living expenses of more than 2 000 Yuan (OR=2.995, 95%CI: 1.135-7.902), cigarette smoking (OR=19.826, 95%CI: 11.385-34.527), and using companions' e-cigarettes (OR=9.141, 95%CI: 5.534-15.101) and thinking that people around me support my use of e-cigarettes (OR=2.673, 95%CI: 1.426-5.013) were risk factors for e-cigarette use among college students.
Conclusions
There is a low awareness rate of e-cigarette use among college students in Guiyang City, and the majority oppose e-cigarette use, with a low proportion of attempt to use e-cigarettes. Age, source of students, monthly living expenses, e-cigarette smoking, knowledge on e-cigarette use and use of companions' e-cigarettes may affect the attempt to use e-cigarettes.

Objective To assess the diagnostic value of multiple-slice spiral CT (MSCT) perfusion imaging technique in pancreatic cancer by measuring and comparing the dynamical characteristics of blood flow between normal pancreas and pancreatic cancer. Methods The CT perfusion imaging were obtained using Siemens Somatoma MSCT scanner in 44 patients with normal pancreas tissue and 18 patients with pancreatic cancer. The mean blood flow (BF),blood volume (BV), time to start (Trs), time to peak (TIP), permeability and patlak blood volume (pBV) were measured and statistically analyzed by using Siemens Body peHusion software package. Results The mean BF, BV, Trs, TIP, permeability and pBV of normal pancreas were: (90.60±29.25) ml·100 ml-1·min-1, (190.35±43.8) ml/L, (205.3±160.2) s, (1403.5±334.0)s, (99.47±49.9) 0.5 ml·100 ml-1·min-1, (157.8±52.5) ml/L, respectively. The mean BF, BV, TTS, TrP, per-meability and pBV of pancreatic cancer were (22.9±10. 63) ml·100 ml-1·min-1, (52.38±18.08) ml/L, (194.3±76.0) s, (1549.5± 308.5)s, (115.25±33.55) 0.5 ml·100 ml-1·min-1, (83.16±41.45) ml/L respectively. The mean BF, BV, pBV and permeability between normal pancreas and pancreatic carcinoma were statistically significant (P<0.01). However the mean TTS and TIP between normal pancreas and pancreatic carcinoma were not statistically significant (P>0.05). Conclusion There are significant differences between perfusion values of pancreatic carcinoma and normal pancreatic tissue, and MSCT perfusion imaging is helpful in diagnosing pancreatic carcinoma.
