This paper evaluates the impact of basic medical insurance on the health status of flexible employees based on the CFPS three-period balanced panel data from 2016 to 2020,using Ordered Probit Model and Two-way Fixed Effects Model.It is found that basic medical insurance significantly promotes the physical and mental health of flexible employees.Further heterogeneity analysis reveals that the health performance of basic medical insurance was particularly significant for middle-aged and old-aged,rural,east-central and better-educated flexible employees.In addition,the mediation effect analysis indicates that basic medical insurance promots the health of flexible employees through the mediation channels of improving the utilization of medical services and reducing the burden of disease costs.This paper suggests promoting the comprehensive participation of flexible employees;improving the medical insurance system for middle-aged and elderly flexible employees;accelerating the sinking of high-quality medical resources to rural and western areas;and actively exploring a new mode of participation in medical check-ups by flexible employees,with a view to lowering the incidence of serious illnesses and major illnesses among flexible employees and improving health performance.

AIM To evaluate the quality of Yanyangke Mixture.METHODS The HPLC fingerprints were established,after which cluster analysis,principal component analysis and partial least squares discriminant analysis were performed.The contents of liquiritin,rosmarinic acid,sheganoside,irisgenin,honokiol,monoammonium glycyrrhizinate,irisflorentin,isoliquiritin and magnolol were determined,the analysis was performed on a 35 ℃ thermostatic Agilent ZORBAX SB-C18 column(5 μm,250 mmx4.6 mm),with the mobile phase comprising of 0.1％phosphoric acid-acetonitrile flowing at 1 mL/min in a gradient elution manner,and multi-wavelength detection was adopted.RESULTS There were ten common peaks in the fingerprints for twelve batches of samples with the similarities of more than 0.9.Various batches of samples were clustered into three types,three principal components displayed the acumulative variance contribution rate of 87.448％,peaks 5、14(honokiol),3(liquiritin),11(monoammonium glycyrrhizinate)and 15(asarinin)were quality markers.Nine constituents showed good linear relationships within their own ranges(r＞0.999 0),whose average recoveries were 98.5％-103.6％with the RSDs of 0.92％-1.7％.CONCLUSION This stable and reliable method can provide a basis for the quality control of Yanyangke Mixture.

Even though the combined use of ultrasound (US) and alpha-fetoprotein (AFP) is recommended for the surveillance of hepatocellular carcinoma (HCC), the utilization of AFP has its challenges, including accuracy dependent on its cut-off levels, degree of liver necroinflammation, and etiology of liver disease. Though various studies have demonstrated the utility of protein induced by vitamin K absence II (PIVKA-II) in surveillance, treatment monitoring, and predicting recurrence, it is still not recommended as a routine biomarker test. A panel of 17 experts from Asia-Pacific, gathered to discuss and reach a consensus on the clinical usefulness and value of PIVKA-II for the surveillance and treatment monitoring of HCC, based on six predetermined statements. The experts agreed that PIVKA-II was valuable in the detection of HCC in AFP-negative patients, and could potentially benefit detection of early HCC in combination with AFP. PIVKA-II is clinically useful for monitoring curative and intra-arterial locoregional treatments, outcomes, and recurrence, and could potentially predict microvascular invasion risk and facilitate patient selection for liver transplant. However, combining PIVKA-II with US and AFP for HCC surveillance, including small HCC, still requires more evidence, whilst its role in detecting AFP-negative HCC will potentially increase as more patients are treated for hepatitis-related HCC. PIVKA-II in combination with AFP and US has a clinical role in the Asia-Pacific region for surveillance. However, implementation of PIVKA-II in the region will have some challenges, such as requiring standardization of cut-off values, its cost-effectiveness and improving awareness among healthcare providers.

COVID-19 has been prevalent for three years. The virulence of SARS-CoV-2 is weaken as it mutates continuously. However, elderly patients, especially those with underlying diseases, are still at high risk of developing severe infections. With the continuous study of the molecular structure and pathogenic mechanism of SARS-CoV-2, antiviral drugs for COVID-19 have been successively marketed, and these anti-SARS-CoV-2 drugs can effectively reduce the severe rate and mortality of elderly patients. This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.

Objective:To explore the effect of predictive nursing based on group management model on the recovery of elderly anesthesia patients, the quality of postoperative recovery and the complications during the recovery period.Methods:From May 2020 to May 2021, 190 elderly surgical patients admitted to the Postanesthesia Care Unit (PACU) of the First Affiliated Hospital with Nanjing Medical University in the Department of Anesthesia and Perioperative Medicine were selected by the convenient sampling. The patients were randomly divided into observation group and control group with 95 cases each. The control group received routine nursing, while the observation group received predictive nursing based on group management model. Before entering the PACU (before intervention) and before leaving the PACU (after intervention) , the Aldrete Score and the Quality of Recovery 40 Questionnaire (QoR-40) were used to evaluate the patients' recovery and postoperative recovery quality, and the complications of the two groups in the recovery period were recorded and compared.Results:After intervention, the Aldrete score and postoperative recovery quality score of the observation group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . The total incidence of complications in the observation group was 4.21% (4/95) , which was lower than 11.58% (11/95) in the control group with a statistical difference ( P<0.05) . Conclusions:Predictive nursing based on group management model can effectively improve the recovery of elderly anesthesia patients and the quality of postoperative recovery, and reduce the occurrence of complications during the recovery of patients.

Objective:To investigate the diagnostic value of ultrasonography in Poland′s syndrome.Methods:From February 2016 to December 2020, the ultrasonographic images of 15 patients with Poland′s syndrome diagnosed by Provincial Hospital Affiliated to Shandong First Medical University were retrospectively analyzed, and the ultrasonographic features were summarized.Results:High-frequency ultrasound could clearly show the anatomical structures of each layer of the chest wall of the patients with Poland′s syndrome. The sonogram of Poland′s syndrome mainly showed the absence of all or part of the pectoralis major on the affected side, some of which were combined with the absence of pectoralis minor. The difference between the thickness of the affected chest wall and the healthy side was statistically significant ( P<0.01). Among the 15 cases of Poland′s syndrome, 11 cases had brachydactyly or syndactyly. Ultrasound showed that the bifurcation position of the common palmar digital artery of the middle finger was lower than that of the healthy side. Conclusions:The ultrasonography is an effective imaging method for diagnosis of Poland′s syndrome.

Aortoiliac occlusive disease (AIOD) refers to the stenosis and occlusion of the distal abdominal aorta and(or) bifurcation of the aortoiliac artery,which is mainly caused by atherosclerosis,leading to pelvic and lower limb ischemia.Open surgery has always been the main treatment for complex AIOD.However,in recent years,with the development of endovascular surgery technologies and medical instruments,its treatment concept has been greatly changed.More and more clinical evidence has proved that the long-term efficacy of endovascular therapy is not inferior to that of traditional open surgery,so minimally invasive endovascular therapy has become the preferred treatment for AIOD.
