Objective To investigate the change of serum cancer antigen(CA) 125 in patients with pleural effusion.Methods One hundred and twenty-eight patients with pleural effusion were admitted to the Naval General Hospital of People's Liberation Army from January 2010 to September 2012 were selected as our subjects.The level of serum CA125 was measured.The difference of serum CA125 positive rate and level were compared according to gender,pleural effusion nature,quantity and pleural effusion chest area; And the difference of patients with malignant pleural effusion tuberculosis,inflammatory,exudative pleural effusion based on above indicators.The correlation between serum CA125 level and pleural effusion depth were analyzed.Results The positive proportions of CA125 were 83.3％ (35/42) and 76.7 ％ (66/88) of patients with malignant and benign effusion respectively,and there was no significant difference (x2 =0.74,P ＞ 0.05).The serum CA125 level of patients with malignant pleural effusion was significantly higher than benign ones ((177.8 ± 31.4) U/ml vs.(110.6 ± 13.6) U/ml,t =31.24,P ＜ 0.05).There were no significant difference in the positive proportion of serum CA125 between malignant,tuberculous,inflammatory and transudative pleural effusion(75.8％ (25/33),70.0％ (20/29),87.5％ (21/24) and 83.3％ (35/42),P ＞ 0.05).Serum CA125 levels of patients with malignant pleural effusion were significantly higher than that with inflammatory ((177.8 ± 31.4) U/ml vs.(72.5 ± 12.8) U/ml,P ＜ 0.05),but the differences were not significant among malignant,tuberculous and transudative pleural effusion group((140.6 ± 28.2) U/ml,(154.3 ± 30.5) U/ml,P ＞ 0.05).The serum CA125 levels of patients with small,moderate and large effusions were (56.4 ± 18.2) U/ml,(120.2 ± 24.5) U/ml and (185.5 ± 34.6) U/ml respectively,and the difference among these groups were significant(F =296.03,P ＜ 0.05).Serum CA125 levels was positively correlated with pleural fluid depth (r =0.56,P ＜0.01).Different gender,pleural effusion parts serum CA125 positive rate and the different levels were not statistically significant (P ＞ 0.05).Conclusion Serum CA125 increased in patients with benign and malignant pleural effusion,and serum CA125 was not severed as the diagnosis biomarker in differentiating benign and malignant pleural effusion.Serum CA125 levels is helpful in monitoring the change of pleural fluid size due to the relation with depth of pleural fluid.

Objective To explore the relationship between obstructive sleep apnea-hypopnea syndrome (OSAHS) and metabolic syndrome (MS) in obese middle-aged and older men. Methods We selectively recruited 154 obese middle-aged and older men matched for body mass index (BMI) and age. The polysomnography was performed for diagnosing OSAHS and for discriminating disease severity. The BMI, waist circumference, blood pressure, plasma glucose and lipid profiles were measured and analyzed in all subjects. Appropriate statistical methods were used to compare the components of MS in each group. Logistic regression was taken to elucidate the relationship between OSAHS and MS. Results Compared to control group, severe OSAHS group had significantly lower high density lipoprotein cholesterol level [( 1.03 ± 0.29 ) mmol/L vs. ( 1.31 ± 0. 38) mmol/L,P＜0. 05] and higher fasting glucose [(6.61±1.76) mmol/L vs. (5.47±0.64) mmol/L, P＜0. 05]as well as higher systolic blood pressure [( 133 ± 13) mm Hg vs. ( 125 ± 12) mm Hg, P＜0. 05] and diastolic blood pressure [(99±10) mm Hg vs. (80±5) mm Hg, P＜0. 05]. The prevalence of MS was significantly higher in OSAHS group than in control group (mild OSAHS group: 25.7%,moderate OSAHS group: 46. 5%, severe OSAHS group: 84.4%, control group: 16. 1 %, all P＜0. 01). OSAHS was independently associated with an increased prevalence of MS Odds ratio, 6.16).Conclusions OSAHS is independently associated with MS in obese middle-aged and older men.

Objective To investigate the effects of arsenic trioxide(ATO) on anti-dsDNA antibody and lymphocyte subsets proliferation in splenic cells of MRL/lpr mice.Methods MRL/lpr mice were divided into three groups: ATO group(0.4 mg/kg?d,ip),sodium chloride(NS) group(0.25 mL,ip),and cyclophosphamide(CTX) group(50 mg/kg?qw,ip).The control group consisted of 12 syngeneic normal C57/BL mice,which were sub-divided into ATO group(0.4 mg/kg?d,ip) and NS group(0.25 mL,ip).After two-month treatment,all mice were killed and their bodies and spleens were weighed.Anti-dsDNA antibody in serum were detected by ELISA.The percentage of different cell subsets was checked through flow cytometry.Results(1)The spleen index、serumlevel of anti-dsDNA antibody and the percentages of CD19+、CD3+、CD3+CD4+ lymphocytes in ATO group were much lower than those in NS group of MRL/lpr mice(P0.05). Conclusion Arsenic trioxide can inhibit the activation of T and B lymphocytes,increase the percentage of NK cell and reduce the serum level of auto-antibody.And it was of no effect in the normal mice.

Objective To investigate the influence of the nursing intervention on the ankle-brachial pulse wave velocity (PWV) and the ankle-brachial index (ABI) in patients with newly diagnosed type 2 diabetes mellitus. Methods Eighty patients with newly-diagnosed type 2 diabetes mellitus were selected and were completely randomly divided into the intervention group (40 patients) and the control group (40 patients). In the intervention group, the closed integrated nursing management mode was applied. Group health records were established and the nursing management group mode of chronic diseases was applied. The chronic disease management team was organized with specialist physicians, chronic disease specialist nurses and general practice nurses who were specialized trained and got related qualification. The whole team diagnosed patients in hospital and out of hospital, gave mental intervention and daily life guidance to patients (diet, sports and so on). Outside of hospital, the telephone follow-up was made every week; the regular family visit was made and the guidance was given to patients every month; the related presupposed indicators were tested every three months. All the patients who were enrolled in the chronic disease management team were given the pre-job training to fully understand their responsibilities, obligations, work contents, etc. in the team. They also signed the team's responsibility statement. In the control group the traditional diabetes nursing management mode was used. After two years intervention, the early detection atherosclerosis blood indexes (PWV and ABI) of patients in the two groups were compared. Results Before the intervention, there was no significant difference in the PWV or the ABI between the two groups (P> 0.05). After the intervention, the PWV in the intervention group was (1 552±462)cw/s, which was significantly different compared with that in the control group(1 613±417)cw/s (t=2.031, P=0.047). Moreover, in the intervention group, the PWV before the intervention was significantly different compared to the PWV after the intervention(t=2.533,P=0.008). After the intervention, the ABI was improved, but the ABI in the intervention group was not significantly different compared with that in the control group. In the intervention group, the ABI before the intervention was not significantly different from that after the intervention(P>0.05). Conclusions The closed nursing management mode can improve the PWV value in patients with newly diagnosed type 2 diabetes mellitus and delay the development of atherosclerosis.

Objective? To explore the application effect of remote management mode for essential hypertensive patients in the army. Methods? By purposive sampling, a total of 70 male army cadres who had been diagnosed as essential hypertension admitted or during health check in the Sixth Medical Center of PLA General Hospital since 2017 were selected as the research objects. The remote management mode was adopted for them in the intervention. Re-examination was conducted for them one year after implementing the remote mode of management. The patients' blood pressure, lifestyle modification status, and related knowledge acquisition about hypertension were compared before and after the management. Results? The systolic and diastolic blood pressures of patients after intervention were lower than those before intervention, and the differences were statistically significant (P＜ 0.01). After intervention, patients' compliance with medication, salt control behavior, alcohol restriction and exercise were better than those before intervention, and the differences were statistically significant (P＜0.01). The score of hypertension related knowledge after intervention was higher than that before intervention,and the difference was statistically significant (P＜0.01). Conclusions? The remote management mode on blood pressure can achieve good effects in the blood pressure management of the patients with hypertension in the army.

Objective:To examine the prevention effecacy and safety of preprotein convertase subtilisin-kexin 9 (PCSK9) inhibitors in stroke in patients with atherosclerotic cardiovascular disease (ASCVD) at primary and secondary prevention.Methods:PubMed, Embase, Web of Science, Cochrane Library, and Wanfang and CNKI databases were searched for randomized controlled trials comparing evolocumab, alirocumab, tafolecimab or inclisiran (experimental group) with placebo or conventional therapy (control group) in hyperlipidemia and ASCVD from inception to March 2024. Valid data were extracted after screening and applying Cochrane Literature quality assessment tool to assess the literature quality. Efficacy outcome (incidences of stroke and ischemic stroke) and safety outcome (cardiovascular mortality, and incidences of aminotransferase increased by more than 3 times, creatine kinase increased by more than 3 times, allergic reaction and hemorrhagic stroke) were recorded. Meta analysis of the extracted data was conducted using Stata software to calculate the risk difference ( RD). Results:Twenty articles (21 randomized controlled trials) were included with 62 799 patients. For primary prevention, no significant difference was found between PCSK9 inhibitors and control groups in stroke incidence ( RD=0.000, 95% CI: -0.002-0.003, P=0.905) or ischemic stroke incidence ( RD=0.001, 95% CI: -0.005-0.006, P=0.824); incidence of creatine kinase increased by more than 3 times in the PCSK9 inhibitors group was significantly decreased compared with that in the control group ( RD=-0.005, 95% CI: -0.010-0.000, P=0.039). For secondary prevention, PCSK9 inhibitors group had significantly reduced stroke incidence ( RD=-0.004, 95% CI: -0.006--0.002, P<0.001) and ischemic stroke incidence ( RD=-0.003, 95% CI: -0.005--0.002, P<0.001) compared with control group; no significant differences in cardiovascular mortality, or incidences of aminotransferase increased by more than 3 times, creatine kinase increased by more than 3 times, allergic reaction and hemorrhagic stroke were noted between the PCSK9 inhibitors group and control group ( P>0.05). Conclusion:PCSK9 inhibitors in primary prevention have no significant effect on stroke or ischemic stroke incidences, but can decrease the incidence of creatine kinase increased by more than 3 times; PCSK9 inhibitors in secondary prevention can reduce stroke and ischemic stroke incidences without increasing complications and thus enjoying certain safety.
