ObjectiveTo systematically review the purchase willingness rate and influencing factors of long-term care insurance in Chinese population.MethodsCNKI, VIP, WanFang Data, EMbase and PubMed databases were electronically searched to collect cross-sectional studies on the purchase willingness rate of long-term care insurance in China from inception to March 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using Stata 16.0 software.ResultsA total of 66 cross-sectional studies involving 151 231 subjects were included. The results of the meta-analysis showed that the purchase willingness rate of long-term care insurance in China was 52.4% (95%CI 48.1% to 56.8%). Subgroup analysis showed that: among the sample characteristic factors, residents who were from the central region of China (56.4%), being studied after 2016 (53.3%), and residing in pilot regions (53.1%) had a higher willingness rate to purchase long-term care insurance. Among demographic factors, the research considered factors of residence and family size (56.2%) contributed to a higher willingness to purchase long-term care insurance, and residents with monthly income from 1 000 yuan to 5 000 yuan (55.4%) and who were unmarried (55.3%) had a higher willingness to purchase long-term care insurance. Among health and concept factors, the research considered factors of insurance and government trust (57.3%), factor of number of chronic diseases (55.0%), and factor of health risk cognition (52.4%) contributed to a higher willingness to purchase long-term care insurance. Among the factors of long-term care insurance system, factor of the government subsidy (60.6%), factor of long-term care insurance price (58.0%) and factor of payment methods (56.2%) contributed a higher willingness to purchase long-term care insurance.ConclusionsCurrent evidence shows that over half of residents are willing to purchase long-term care insurance. However, different factors still affect their purchase willingness. The influencing factors reflect numerous difficulties in the current long-term care insurance system, which requires attention and continuous improvement of policy formulators and related researchers.
Objective To investigate the prognostic factors of severe chronic obstructive pulmonary disease ( COPD) in elderly patients, and to guide the clinical assessment and appropriate interventions. Methods A prospective cohort study was carried out from May 1993 to December 2010. A total of 178 elderly patients with severe COPD were recruited for baseline survey, and followed up for the living conditions, whether used non-invasive ventilation, and causes of death. A survival analysis was performed on all patients stratified by lung function. The significant factors on survival rate were analyzed. Results In this cohort the survival rates were 49% and 12% in five and ten years, respectively. The important factors for prognosis were age [ relative risk( RR) = 1. 043, 95% confidence intervals( 95% CI = 1. 010-1. 050] , forced expired volume in one second ( FEV1 , RR = 0. 019, 95% CI = 0. 007-0. 052) , FEV1% pred ( RR = 1. 045, 95% CI = 1. 012-1. 079) , lung function grade ( RR = 2. 542, 95% CI = 1. 310-4. 931) , body mass index ( BMI, RR= 0. 945, 95% CI = 0. 895-0. 952) , and pulmonary heart disease ( RR = 1. 872, 95% CI = 1. 188- 2. 959) . In severe COPD, non-invasive ventilation ( NIV, RR = 1. 167, 95% CI = 0. 041-1. 674) , pulmonary heart disease ( RR = 3. 805, 95% CI = 1. 336-10. 836) , FEV1 ( RR = 0. 081, 95% CI = 1. 001-1. 168) , and arterial partial of oxygen ( PaO2 , RR=0. 956, 95% CI =0. 920-0. 993) were the independent predictors.The patients using NIV had longer survival than those without NIV. The 5 and 10 years survival rate in the patients with NIV were 78% and 50% , much higher than those without ventilation which were 30% and 25% , respectively. In extremely severe COPD, FEV1 ( RR=1. 059, 95% CI =1. 015-1. 105) , arterial partial of carbon dioxide ( PaCO2 , RR=1. 037, 95% CI = 1. 001-1. 074) , age ( RR= 1. 054, 95% CI = 1. 013-1. 096) and pulmonary heart disease ( RR = 1. 892, 95% CI = 1. 125-3. 181) were the independent predictors. Conclusions Age, BMI, FEV1 , PaO2 , PaCO2 , pulmonary heart disease, and NIV were prognostic factors in elderly patients with severe COPD. The prognostic factors between severe and extremely severe COPD were not identical. Patients with severe COPD should be given early intervention, including progressive nutritional support, and long-term home oxygen therapy combining with NIV.
Aiming at the shortcomings in the theory and practice of integrated elderly care and medical services in China, using the methods of literature analysis and comparative analysis, we summarize four typical models of integrated elderly care and medical services, namely, the American commercial pension model, the British national tax financing system pension model, the Japanese national security transformation, and the German long-term care insurance system, and compare the four models systematically from the aspects of system overview, service principle, operation mode, financing supervision, etc. The enlightenment for the policy and practice development of integrated elderly care and medical services in China is obtained: firstly, the service concept should be innovated; secondly, it is important to improve the relevant legal protection and supporting measures; thirdly, the refinement of the integrated elderly care and medical service projects are supposed to be promoted; fourthly, a multi-party linkage mechanism ought to be establishd; and fifthly, community endowment model should be advocated.
Objective To evaluate the effect of releasable sutures on shallow anterior chamber, filtering bleb and long-term intraocular pressure (IOP). Methods We searched MEDLINE (1971 to 2007), OVID (1971 to 2007) and National Science and Technology Library (1971 to 2007). Randomized controlled trials (RCTs) of the effect of releasable sutures on trabeculectomy were collected. Study selection and assessment, data collection and analyses were undertaken and cross-checked by two reviewers. Meta-analyses were performed with The Cochrane Collaboration’s RevMan 4.2.10 software. Results Six RCTs involving 341 eyes were included. Significant differences were observed in the reduction of postoperative shallow anterior chamber (RD –0.23, 95%CI –0.31 to –0.14, Plt;0.000 01) and functional filtering blebs (RD –0.15, 95%CI –0.27 to –0.02, P=0.02). But, no differences were observed for the control of long-term IOP (SMD –0.13, 95%CI –0.37 to 0.10, P=0.27). Conclusion The evidence currently available showed that releasable sutures could reduce the incidence of shallow anterior chamber and has no beneficial effect in controlling long-term IOP. The current evidence is insufficient to define the efficacy of maintaining functional filtering blebs. Further large-scale, high-quality randomized controlled trials are needed.
ObjectiveTo review and analyze the long-term results of delayed repair of median nerve injury. MethodsBetween January 2004 and December 2008, 228 patients with median nerve injury undergoing delayed repair were followed up for more than 4 years, and the clinical data were retrospectively analyzed. There were 176 males (77.19%) and 52 females (22.81%), aged 2-71 years (median, 29 years). The main injury reason was cutting injury in 159 cases (69.74%);203 cases had open injury (89.04%). According to the injury level, injury located at area I (upper arm) in 38 cases (16.67%), at area II (elbow and proximal forearm) in 53 cases (23.25%), at area III (anterior interosseous nerve) in 13 cases (5.70%), and at area IV (distal forearm to wrist) in 124 cases (54.39%). The delayed operations included delayed suture (50 cases, 21.93%), nerve release (149 cases, 65.35%), and nerve graft (29 cases, 12.72%). ResultsFor patients with injury at area I and area II, the results were good in 23 cases (25.27%), fair in 56 cases (61.54%), and poor in 12 cases (13.18%) according to modified Birch and Raji’s median nerve grading system;there was significant difference in the results between 3 repair methods for injury at area II (χ2=6.228, P=0.044), but no significant difference was found for injury at area I (χ2=2.241, P=0.326). Twelve patients (13.18%) needed musculus flexor functional reconstruction. Recovery of thenar muscle was poor in all patients, but only 5 cases (5.49%) received reconstruction. Thirteen cases of nerve injury at area III had good results, regardless of the repair methods. For patients with injury at area IV, the results were excellent in 6 cases (4.84%), good in 22 cases (17.74%), fair in 72 cases (58.06%), and poor in 24 cases (19.35%) according to Birch and Raji’s grading system;there was significant difference in the results between 3 repair methods (χ2=12.646, P=0.002), and the result of delayed repair was better. ConclusionThe results of delayed repair is poor for all median nerve injuries, especially for high level injury. The technique of repair methods vary with injury level. For some delayed median nerve injuries, early nerve transfer may be a better choice for indicative patients.

In 2025, the American Cancer Society published "Cancer statistics, 2025", which projected cancer data for the upcoming year based on incidence data collected by central cancer registries (through 2021) and mortality data obtained from the National Center for Health Statistics (through 2022). Similarly, the National Cancer Center of China released "Cancer incidence and mortality in China, 2022" in December 2024, analyzing data from 22 cancer registries across the country. This study provides a comparative analysis of cancer incidence and mortality trends in China and the United States during the same period, with a focus on sex- and age-specific distributions and long-term changes in cancer patterns. Long-term trends indicate that lung and liver cancer mortality rates in China have declined, primarily due to tobacco control measures and hepatitis B vaccination programs. However, the burden of gastric and esophageal cancers remains substantial. In the United States, mortality rates for colorectal and lung cancers have continued to decline, largely attributed to widespread screening programs and advances in immunotherapy. As economic growth and social development, China’s cancer profile is gradually shifting towards patterns observed in countries with high human development index. However, the prevention and control of upper gastrointestinal cancers remains a critical public health challenge that requires further attention.
The new effective systemic treatment strategy has "created" many long-term stage Ⅳ non-small cell lung cancer (NSCLC) survivors, and surgeons should pay attention to those individual ineffective lesions of long-term survivors. Besides, the new effective systemic treatment strategy may have changed the original concept and population of oligometasis. To intervene the oligo-progression lesions of long-term stage Ⅳ survivors, particularly after effective systemic treatment, at appropriate time with appropriate way might be the main task of surgery in the future.
