Osteoarthritis （OA） is a common chronic， highly prevalent， painful， and disabling degenerative joint disease. It has imposed a heavy burden on social healthcare and patients' psychology and economy due to its clinical symptoms such as impaired joint mobility and severe joint pain and the immature therapies. Studies have shown that OA is closely associated with articular cartilage dysfunction， synthesis and degradation disorders of chondrocyte extracellular matrix （ECM）， and joint inflammation. Moderate autophagy can restore the function of damaged chondrocytes， regulate chondrocyte apoptosis， and promote the synthesis and metabolism of ECM to alleviate the inflammation of joints and delay the onset and progression of OA. According to the clinical symptoms， OA can be classified into the category of impediment in traditional Chinese medicine. With the theories of holistic conception， treatment based on syndrome differentiation， and individualised diagnosis and treatment， traditional Chinese medicine has demonstrated definite effects in the treatment of OA in thousands of years of practice. Moreover， traditional Chinese medicine causes mild adverse reactions， and the patients have high tolerance and acceptance. This paper briefly explains the roles of autophagy and the related regulatory proteins， such as Unc-51-like autophagy-activated kinase 1 （ULK1）， Beclin-1， and microtubule-associated protein light chain 3 （LC3）， and details the latest research achievements in the prevention and control of OA by traditional Chinese medicines and its related markers via the regulation of autophagy， so as to provide a idea for the in-depth research in this field and the clinical application of traditional Chinese medicine in preventing and treating OA.

Portal vein thrombosis （PVT） is one of the common complications during the natural course of liver cirrhosis and has an important influence on the progression of liver cirrhosis. This article mainly summarizes the research advances in the risk factors for PVT. There are many risk factors for PVT， and Virchow’s triad， namely venous stasis， hypercoagulability， and vascular endothelial injury and systemic inflammation caused by surgery or trauma， are considered the main reasons for the development and progression of PVT. At present， more prospective studies are still needed to validate the predictive models for the risk of PVT that have certain application prospects in clinical practice. Cirrhotic patients with PVT tend to have a poor prognosis， and complete obstructive PVT is associated with increased mortality after liver transplantation. Recent studies have shown that prophylactic anticoagulant therapy is safe and effective in patients with liver cirrhosis and can thus help with the prevention and treatment of PVT.

Objective To study the changes in related parameters after secondary preparation of blood components,in order to further improve the quality of blood components.Methods Different centrifugation conditions were selected for the preparation of primary blood component red blood cells in additive solution leukocytes reduced,and the quality was tested.Then,using the red blood cells in additive solution leukocytes reduced as the initial blood for secondary preparation,and the red blood cells were washed through the Haemonetics ACP 215 device,and the quality was tested.The preparation pa-rameters of blood components were observed,compared and optimized.Results Under comparable centrifugation effects of different centrifugation conditions,the quality control items,which of primary blood components of red blood cells in additive solution leukocytes reduced and frozen plasma prepared by the separation,such as volume,hemoglobin,hematocrit and re-sidual white blood cells met the relevant national standards.And the quality control items of secondary blood components of washed red blood cells such as the hemoglobin and superalbumin content both met the relevant national standards,while vol-ume exceeded the standard by 7-14 mL,which can be operated to the standard range.In addition,the recovery rate of red blood cells and the clearance rate of plasma protein could reach 75%and 99%respectively.Conclusion There is a certain correlation between primary and secondary preparation of blood components,but the relevant parameters of secondary prepa-ration of blood components can be flexibly adjusted according to the actual situation to ensure that the quality of prepared blood component products meet the national standards,thus ensuring clinical treatment effect and safety.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Objective:To explore the characteristics of brain dynamic activity in patients with schizophrenia by using functional magnetic resonance imaging(fMRI).Methods:Forty-three patients with schizophrenia and 31 normal controls were recruited and under fMRI scanning.The Positive and Negative Symptom Scale(PANS)was used to assess the severity of clinical symptoms.The DPABI software were used to compute dReHo and dFC.Granger causality analysis was used to calculate the effective connectivity between the significant brain regions of dReHo and the whole brain.Two sample t-test was performed to compare the difference of dReHo and dFC be-tween patients with schizophrenia and normal controls.Results:The dReHo of left postcentral gyrus(LPG)(P＜0.01,cluster-level FWE corrected)in patients with schizophrenia was decreased.The Dfc was increased between left postcentral and left middle frontal gyrus,left superior medial frontal gyrus,right calcarine,left medial cingulum gyrus,right supplementary motor area(P＜0.01,uncorrected).Compared with normal controls,patients with schiz-ophrenia showed decreased effective connectivity from LPG to right putamen.Conclusion:It suggests that the ab-normal functional activity of the postcentral gyrus mightcontribute to the neural physiopathology in patients with schizophrenia.

【Objective】 To investigate the preparation quality and clinical application effect of pooled platelets with leukocytes reduced. 【Methods】 The quality and clinical effect of the buffy-coated method prepared pooled platelets leukocytes reduced (experimental group, n=40) and apheresis platelets leukocytes reduced (control group, n=40) were compared. 【Results】 The platelet volume (mL), platelet count (×10¹¹), red blood cell contamination (×10⁸) and residual white blood cell (×10⁶) of the experimental group and control group were 278.90±7.92 vs 276.52±8.01, 2.66±0.09 vs 2.66±0.83, 0.54±0.42 vs 0.83±0.84, 0.29±0.54 vs 0.27±0.51, respectively, with no significant difference. The results of bacterial culture were negative, all met the requirements of relevant national standards. In addition, the CCI (×10^3, 24 h) and PPR (%) were 15.11±9.86 vs 14.61±12.55 and 54.23±18.70 vs 61.41±19.09 respectively, with no significant difference, indicating a certain degree of therapeutic effect. 【Conclusion】 The quality and clinical therapeutic effect of pooled platelets leukocytes reduced were consistent with that of apheresis platelets leukocytes reduced.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.

Various c-mesenchymal-to-epithelial transition (c-MET) inhibitors are effective in the treatment of non-small cell lung cancer; however, the inevitable drug resistance remains a challenge, limiting their clinical efficacy. Therefore, novel strategies targeting c-MET are urgently required. Herein, through rational structure optimization, we obtained novel exceptionally potent and orally active c-MET proteolysis targeting chimeras (PROTACs) namely D10 and D15 based on thalidomide and tepotinib. D10 and D15 inhibited cell growth with low nanomolar IC₅₀ values and achieved picomolar DC₅₀ values and >99% of maximum degradation (D_max) in EBC-1 and Hs746T cells. Mechanistically, D10 and D15 dramatically induced cell apoptosis, G1 cell cycle arrest and inhibited cell migration and invasion. Notably, intraperitoneal administration of D10 and D15 significantly inhibited tumor growth in the EBC-1 xenograft model and oral administration of D15 induced approximately complete tumor suppression in the Hs746T xenograft model with well-tolerated dose-schedules. Furthermore, D10 and D15 exerted significant anti-tumor effect in cells with c-MET^Y1230H and c-MET^D1228N mutations, which are resistant to tepotinib in clinic. These findings demonstrated that D10 and D15 could serve as candidates for the treatment of tumors with MET alterations.

Objective:To investigate the prevalence and risk factors of diabetic peripheral artery disease (PAD) in patients with type 2 diabetes mellitus (T2DM) managed in primary health care in China.Methods:A total of 2 528 T2DM patients were selected using a two-stage cluster random sampling method based on the baseline survey of the "China Diabetic Foot Prevention Model Project." The study was conducted in 2015 among T2DM patients in 8 primary healthcare centers in Changshu county and Jiang'an district of Wuhan, China. Data collection methods included a questionnaire, body measurement, and blood glucose detection. The Ankle-Brachial Index (ABI) is the most widely used noninvasive vascular test. A binary logistic regression model was used to analyze the influence factors.Results:The prevalence of PAD was 11.2% among the diabetic patients managed in primary health care in the two cities. The prevalence of PAD under 55 years old, 55- years old, 65- years old, and ≥75 years old were 7.8%, 6.0%, 12.9% and 22.5%, respectively. Multivariate stepwise logistic regression identified influence factors included older age, higher education level, smoking, drinking, postprandial glucose uncontrol, and prior myocardial infarction or angina. Compared to age <55 years, the odds ratio for PAD were 0.74 for 55- years (95% CI: 0.43-1.28), 1.72 for 65- years (95% CI: 1.05-2.81), 3.56 for 75 years and above (95% CI: 2.07-6.11), respectively. Compared to patients with education in primary school and below, the odds ratio was 1.37 (95% CI: 0.97-1.94), 2.48 (95% CI: 1.73-3.55), 1.99 (95% CI: 1.26-3.13) for those with education levels of junior high school, senior high school, and college, respectively. Current smoking ( OR=1.49, 95% CI: 1.02-2.17), current drinking ( OR=0.45, 95% CI: 0.28-0.71), postprandial glucose uncontrol (2 h postprandial plasma glucose >10.0 mmol/L: OR=1.72, 95% CI: 1.22-2.43), and prior myocardial infarction or angina ( OR=2.32, 95% CI: 1.50-3.61) were influencing factors of PAD. Conclusions:Despite the high prevalence of PAD in diabetes managed in primary health care; multiple risk factors are not effectively aware of and under control. It is urgent to promote ABI screening and standardized management for diabetes, especially in primary health care.

Objective:To analyze the trend of liver cancer morbidity and mortality among residents with household registration in certain District, 2017 to 2019.Methods:The crude morbidity and mortality rate of males and females in the whole population were calculated by using the relevant data from the certain District Cancer Registry and Report System and the Cause of Death Surveillance System. The standardized morbidity and mortality rate were calculated according to the age structure of 2000 National Demographic Census and Segi's world population, respectively. Trend in liver cancer morbidity and mortality were evaluated using percent change (PC), annual percentage change, and case-number-weighted annual percent change. Age-specific rates were used to analyze the epidemic trend of liver cancer with age.Results:The crude morbidity rate of liver cancer in the whole population (male and female) of the certain district from 2017 to 2019 were 18.86/100 000, 26.05/100 000 and 11.90/100 000 respectively, and the crude mortality rates were 21.20/100 000, 29.29/100 000 and 13.38/100 000 respectively. The crude morbidity and mortality rate of liver cancer among male showed a downward trend (PC=-16.77% and -20.15% respectively). The crude morbidity and mortality rate of liver cancer among female showed inconsistent changes; however, the crude morbidity rate showed a downward trend, and the crude mortality rate first increased and then decreased (PC=-19.42% and -0.30% respectively). Liver cancer morbidity and mortality rate in male after the age of 30 were increased with age. The two key points of accelerated growth were around the age of 65 and 75, and the peak of morbidity (130.78/100 000) and mortality (201.96/100 000) were after the age of 80. The morbidity and mortality rate were significantly lower in female than those of male aged 60; however, after the age of 65, the morbidity rate was increased rapidly and gradually approached as that of male. After the age of 80 (the peak morbidity and mortality were 104.40/100,000 and 132.87/100,000, respectively), male were about twice as high as those female aged between 75 and 79.Conclusion:Morbidity and mortality rate of liver cancer in the certain District showed an overall downward trend from 2017 to 2019, but it increased with age, and the disease burden was relatively high among the elderly population. Liver cancer mostly occurred in male, so the prevention and control of liver cancer epidemics in middle-aged and elderly should be actively monitored.
