This review introduced the anti-tumor effects of non-steroid anti-inflammatory drugs (NSAIDs) and summarized their possible molecular mechanisms according to recent abroad literatures and our research results. Some evidence showed that the anti-tumor mechanisms of NSAIDs were different in various tumors.NSAIDs decreased the biosynthesis of PGE_2 and regulated the expressions of downstream correlated genes and proteins through restraining abnormal expression of COX-2 in certain neoplasms,which resulted in the inhibition of tumor angiogenesis and proliferation as well as induced apoptosis. But in other cancer cells, NSAIDs, as activators of peroxisome proliferator-activated receptor ? (PPAR?), induced COX-2 expression, promoted the biosynthesis of cyclopentenone prostaglandins (cyPGs). cyPGs further induced tumor cell apoptosis with PPAR? dependently or PPAR? independently. Since their special mechanisms of anti-proliferation and pro-apoptosis, NSAIDs revealed significant synergistic effects with other anti-tumor treatments.

BACKGROUND: MAVERIC (Mitral Valve Repair Clinical Trial) validates the safety and efficacy of the ARTO system. We here report the first two successful cases of utilizing the ARTO system in patients with symptomatic heart failure (HF) with functional mitral regurgitation (FMR) in Asia. METHODS: Two patients, aged 70 and 63, had severe HF with FMR. Transesophageal echocardiography confirmed that the left ventricular ejection fractions were less than 50% with severe mitral regurgitation (MR) in both patients. Optimizing drug treatment could not mitigate their symptoms. Therefore, we used the ARTO system to repair the mitral valve for these patients on March 5 and 6, 2019, respectively. RESULTS: Mitral valve repairs using the ARTO system were successfully performed under general anaesthesia for these two patients. MR was decreased immediately after the procedures in both patients. The 30-day and 3-month transthoracic echocardiography (TTE) revealed a moderate to severe MR in both patients, and the New York Heart Association (NYHA) scales were also partially improved. CONCLUSION The first two cases in Asia indicate that the ARTO system is feasible for patients with heart failure with FMR, and the patient selection appears to be crucial.

Objective To investigate and analyze the clinical efficacy of cefoperazone and Shubatan in the treatment of severe infection in emergency department. Methods 100 cases of severe infection were randomly divided into control group and experimental group, with 50 patients in each group. The control group received routine treatment, and the experimental group was treated with cefoperazone and Shubatan on this basis. Pay close attention to the related vital signs change of the experimental group and the control group, the relevant clinical indicators of the two groups of patients were compared and analyzed. Results After the corresponding treatment, the bacteria removal rate of the experimental group was 90.00%, significantly higher thant 60.00 % of the control group (P<0.05). The effective rate of the experimental group was 90.00%, which was significantly higher than that of the control group (74.00%), which was statistically significant (P<0.05). There were no obvious adverse reactions in the two groups. After treatment, the total score of quality of life in the experimental group was (75.2±11.2) points, and the total score of QOL in the control group was (64.2±9.3) points, which was statistically significant (P<0.05). Conclusion The clinical efficacy of cefoperazone and Shubatan in the treatment of emergency severe infection is satisfactory. It can significantly improve the clinical symptoms and improve the quality of life in patients with severe acute respiratory infection.

OBJECTIVETo evaluate the anginal attack-relieving efficacy and safety of Kuanxiong Aerosol (KA) in patients with coronary heart disease (CHD).

METHODSA total of 780 patients confirmatively diagnosed as CHD angina from November 2011 to December 2012 in 13 medical centers in the mainland area were assigned to 2 groups by blocked randomization, the treatment group (376 cases) and the control group (374 cases). When the angina attacked, patients in the treatment group received sublingual spray three times, 0.6 mL each time, while those in the control group sublingually dissolved Nitroglycerin Tablet (NT), 0.5 mg each tablet. The effective rate of angina relief, efficacy of electrocardiogram (ECG), and the incidence of adverse reactions were observed.

RESULTSThe 3 min and 5 min remission rates of angina attack were 53.72% (202/376) and 94.41% (355/376) in the treatment group, and 47.86% (179/374) and 90.64% (339/374) in the control group. The 95% confidence interval (CI) of the difference between the 2 groups of 3 min and 5 min remission rates of angina attacks were [(-1.84%, 12.32%) and (-1.33%, 6.85%) respectively, P > 0.05]. The total improvement rates of ST-T changes in the treatment group and the control group after treatment were 74.07% and 73.13% respectively (P > 0.05). The adverse reaction rate was 9.31 (35/376 cases) in the treatment group and 22.46% (84/374 cases) in the control group (P < 0.01).

CONCLUSIONKA was not inferior to NT in relieving anginal attacks and improving ischemic ECG changes, and had obviously less adverse reaction.

OBJECTIVETo study the HIV incidence and risk factors among sero-negative spouses of HIV patients in Dehong prefecture of Yunnan province.

METHODSA cohort of sero-negative spouses of the HIV patients had been developed and followed up since November, 2005. HIV new infections and related behaviors had been investigated every six months.

RESULTSBy the end of June, 2008, 790 sero-negative spouses of HIV patients had been recruited, of whom 702 were followed-up for at least one time. During the total 1202.35 person-years, 31 new HIV infections were identified, with an overall incidence of 2.58/100 person-years. The HIV incidence rates were 2.22/100 person-years in 2006, 2.95/100 person-years in 2007 and 2.74/100 person-years in 2008. Data from the Cox proportional hazard regression model indicated that those who resided in Yingjiang county [hazard ratio (HR) = 4.37, 95%CI: 1.48 - 12.90, P = 0.008], ever using drugs (HR = 3.49, 95%CI: 1.09 - 11.18, P = 0.035), or having an HIV-infected spouse who never exposed to antiretroviral treatment (HR = 3.60, 95%CI: 1.41 - 9.16, P = 0.007) were at higher risk for HIV infection.

CONCLUSIONSero-negative spouses of HIV patients in Dehong prefecture of Yunnan province had a relatively high incidence of HIV new infection during 2006-2008. More efforts should put on those people living in these areas, having a history of drug use or having an HIV-infected spouse who had never been exposed to antiretroviral treatment.

BACKGROUNDFemales with acute myocardial infarction (AMI) have a higher risk of adverse outcomes because of receiving less evidence-based medical care. Our aim was to investigate the gender disparity in early death after ST-elevation myocardial infarction (STEMI) in the current era.

METHODSA total of 1429 consecutive patients with STEMI in the Liaoning district were analyzed. We compared hospital care and cardiac event data by sex for in-patients with acute STEMI within 24 hours of symptom onset.

RESULTSIn the emergency reperfusion group (n = 754), in-hospital mortality occurred in 4.2% of the males and 11.2% of the females (P = 0.001). In the non-emergency reperfusion group (n = 675), in-hospital mortality occurred in 13.0% of the males and 22.9% of the females (P = 0.001). Multivariate Logistic regression analysis revealed female sex as an independent risk factor of death for STEMI patients during hospitalization (OR = 1.691, P = 0.007). After controlling for patients who died within 24 hr after admission, female sex was no longer an independent risk factor (OR = 1.409, P = 0.259).

CONCLUSIONFemale sex was an independent risk factor for in-hospital mortality of STEMI patients, which is explained by an excess of very early deaths.

BACKGROUNDIn cardiology, it is controversial whether gender influences prognosis after acute myocardial infarction (MI). We examined the 30-day and 1-year prognosis for female patients with ST-elevation myocardial infarction (STEMI) in Liaoning province, and we analyzed factors that influenced these outcomes.

METHODSThis was a prospective, multicenter, observational study in which patient data were collected by questionnaire at the time of diagnosis and at approximately 30 days and 1 year later by telephone inquiries. Patients were diagnosed with STEMI between June 1, 2009 and June 1, 2010 at any of the 20 hospitals that gave treatment representative of current STEMI treatment in Liaoning Province. Unified follow-up questionnaire was used to visit the STEMI patients.

RESULTSWe analyzed data from a total of 1429 consecutive patients with STEMI in Liaoning province. Female patients were older (70.0 vs. 60.3, P < 0.001) and were less likely to receive emergency reperfusion therapy than male ones (39.2% vs. 58.0%, P < 0.001). Female gender was associated with higher unadjusted 30-day mortality rates (HR = 2.118, 95%CI: 1.572 - 2.854, P < 0.001) and higher unadjusted 1-year mortality rates (HR = 2.174, 95%CI: 1.659 - 2.848, P < 0.001). Multivariate Cox regression analysis showed that female gender was not an independent predictor of 30-day mortality rates (HR = 1.273, 95%CI: 0.929 - 1.745, P = 0.133) nor of 1-year mortality rates (HR = 1.112, 95%CI: 0.831 - 1.487, P = 0.475).

CONCLUSIONSWomen with STEMI appear to be at increased risk of 30-day and 1-year mortality compared with male STEMI patients, but this difference may be explained by older age and less frequent receipt of reperfusion therapy among the women.

PURPOSE: Plasma cells and immunoglobulins (Igs) play a pivotal role in the induction and maintenance of chronic inflammation in nasal polyps. During secondary immune responses, plasma cell survival and Ig production are regulated by the local environment. The purpose of the present study was to investigate the presence of long-lived plasma cells (LLPCs) and specific survival niches for LLPCs in human nasal polyps.METHODS: Nasal mucosal samples were cultured with an air-liquid interface system and the Ig levels in culture supernatants were analyzed by enzyme-linked immunosorbent assay. The characteristics of LLPCs in nasal polyps were determined by immunohistochemistry and immunofluorescence. The expression of neurotrophins as well as their receptors was detected by quantitative real-time polymerase chain reaction, immunohistochemistry, immunofluorescence, and Western blotting.RESULTS: The numbers of CD138⁺ total plasma cells and BCL2⁺ plasma cells were increased in both eosinophilic and non-eosinophilic nasal polyps compared with those in normal tissues. The production of IgG, IgA, and IgE was detected in culture supernatants even after a 32-day culture of nasal polyps. Although the total numbers of plasma cells were decreased in nasal polyps after culture, the numbers of BCL2⁺ plasma cells remained stable. The expression of nerve growth factor (NGF) as well as tropomyosin receptor kinase (Trk) A, a high-affinity receptor for NGF, was upregulated in both eosinophilic and non-eosinophilic nasal polyps. In addition, BCL2⁺ plasma cell numbers were positively correlated with NGF and TrkA mRNA expression in nasal mucosal tissues. Polyp plasma cells had the expression of TrkA.CONCLUSIONS: Human nasal polyps harbor a population of LLPCs and NGF may be involved in their prolonged survival. LLPCs may be a novel therapeutic target for suppressing the local Ig production in nasal polyps.
