This paper discusses the pathogenesis and treatment strategies of skin cancer based on the theory of "spleen deficiency-sweat pore obstruction-toxin accumulation". It is believed that although the disease is located in the skin and body hair， it is not only the localized disorder but closely related to the imbalance of qi and blood of zang-fu （脏腑） organs. The core of the disease is the synergistic disorder of spleen， sweat pore， and skin and body hair. The disease progression follows a dynamic evolution from spleen deficiency with loss of nourishment， initial closure of sweat pore to binding of dampness and stasis with obstruction of sweat pore， and then to cancer toxin consolidation with damage to sweat pore. Based on this， three principles of building earth， opening sweat pore and attacking toxin are established. The method of fortifying spleen and raising the clear aims to consolidate the root and restore validity， with commonly used prescriptions including modifications of Buzhong Yiqi Decoction （补中益气汤）， Liujunzi Decoction （六君子汤） and Guipi Decoction （归脾汤）. The method of opening sweat pores with acrid-moistening medicinals is suggested when dredging and unblocking the sweat pore， commonly using acrid and warm dispersing medicinals， supplemented with herbs that nourish fluids and moisten dryness. The method of clearing heat and removing toxin is to break cancer toxin directly， and modifications of prescriptions such as Wuwei Xiaodu Beverage （五味消毒饮）， Xiaolei Pills （消瘰丸） and Xihuang Pills （犀黄丸） are commonly used. These approaches provide valuable ideas for the prevention and treatment of skin cancer with traditional Chinese medicine.

Objective:To evaluate the sample preparation proficiency and storage proficiency of 11 clinical biobanks in Beijing through simulated experiments, and to establish an assessment method for the quality comparability of biological samples.Methods:An exploratory research design was adopted. In November 2023, artificial composite serum quality control materials containing six recombinant human protein markers—recombinant human alanine aminotransferase (rhALT), recombinant human aspartate aminotransferase (rhAST), recombinant human creatine kinase (rhCK), recombinant human creatine kinase-MB (rhCK-MB), recombinant human B-type natriuretic peptide (rhBNP), and recombinant human troponin I (rhTNI)—were distributed to 11 clinical biobanks in Beijing City. Sample preparation and storage followed the standardized operating procedures. Proficiency differences were assessed through statistical analysis.Results:Three-way repeated measures ANOVA revealed all six protein markers showed a declining trend over storage time in ultra-low-temperature environments ( F values 11.68-4 179.66, all P<0.01). However, neither long-term/temporary refrigerator types ( F values 0.01-1.23, all P>0.05)nor placement locations within refrigerators significantly affected the stability of these six proteins ( F valus 0.03-1.47, all P>0.05). The biases in detection results for rhALT, rhAST, rhTNI, and rhBNP at different storage time points were within the allowable bias limits for each item, supporting their use as markers for protein stability in biobank samples. All 11 institutions passed the storage proficiency assessment. In the preparation proficiency assessment, deviations were observed in post-preparation sample results, with a notably high out-of-control rate for rhCK (36.36%). Conclusion:Sample preparation proficiency can serve as a quality control metric for clinical biobanks. Future external quality assessment systems for biobanks should focus on sample preparation rather than storage processes.

Alzheimer's disease(AD)is an age-related neurodegenerative disease with an increasing incidence worldwide.A large number of studies have shown that the incidence rates of hearing loss is high in patients with mild cognitive impairment and Alzheimer's disease,and may be a risk factor for the occurrence and development of cognitive impairment.There is an interaction between the two,but the causal mechanism is still unclear.Early screening and management of hearing impairment may play an important role in the early diagnosis,symptom im-provement and disease progression of Alzheimer's disease.This paper reviews relevant clinical and basic research to discuss the correlation between hearing loss and Alzheimer's disease,and the possible causal mechanism between them.

Aim To investigate the effects of the fangchinoline derivative LYY-32 on the biological prop-erties of the BLM642-1290 DNA helicase,in order to lay a foundation for further research on its antitumor activity.Methods Fluorescence polarization assay,malachite green-phosphate and ammonium molybdate colorime-try,and fluorescein-labeled DNA gel electrophoresis experiments were conducted to study the effects of fangchinoline derivative LYY-32 on the DNA binding activity,ATPase activity,and DNA unwinding activity of BLM642-1290 DNA helicase.The effects of LYY-32 on the DNA unwinding activity of DNA helicase in cells were studied using fluorescent techniques and time-lapse microscopy.Ultraviolet spectral scanning was used to investigate the effects of LYY-32 on the confor-mation of the BLM642-1290 DNA helicase.Results At a concentration of 10 μmol·L-1,the inhibition rate of LYY-32 on BLM642-1290 DNA helicase binding to dsDNA was 53.17％.At a concentration of 5 μmol·L-1,the inhibition rate of LYY-32 on BLM642-1290 DNA helicase binding to ssDNA was 88.49％.The inhibition rate of LYY-32 on the ATPase activity of BLM642-1290 DNA he-licase was 89.3％at a concentration of 50 μmol·L-1.When the concentration of LYY-32 exceeded 5μmol·L-1,its inhibition rate on the DNA unwinding activity of BLM642-1290 DNA helicase was 100％.LYY-32 also significantly inhibited the DNA unwinding ac-tivity of DNA helicase in cells.However,LYY-32 had no effect on the conformation of BLM642-1290 DNA heli-case.Conclusion The DNA binding activity,AT-Pase activity,and DNA unwinding activity of BLM642-1290 DNA helicase could be significantly inhibi-ted by the fangchinoline derivative LYY-32.

Jiaxing city is one of the pilot cities for the Long-term Care Insurance(LTCI)policy in Zhejiang Province.This study examines the current implementation status of Jiaxing's LTCI policy in terms of financing(including financing targets,channels,methods,and standards)and benefit payments(including payment forms,contents,standards,and levels).It summarizes the experiences and challenges encountered during the pilot process.Currently,Jiaxing's LTCI policy has undergone continuous improvement in financing and benefit payment mechanisms.The financing targets now cover both urban and rural residents,and the coverage has expanded from individuals with severe disabilities to include those with severe dementia.The benefit content has been refined,with the introduction of a detailed service project directory and service pricing.For the future,it is recommended to expand the coverage to individuals with moderate disabilities,based on the fund's capacity and sustainability,and to differentiate benefit standards according to the severity of disability.Furthermore,it is suggested to strengthen the responsibilities of employers and individuals,diversify financing channels,and gradually explore an independent financing mechanism for LTCI.A combination of fixed-amount and proportional financing methods should be considered,alongside factors such as intergenerational equity and population aging trends,to establish a scientific and dynamic premium adjustment mechanism.

OBJECTIVE To analyze the levels of NOD like receptor thermal protein domain associated protein 3(NLRP3),nuclear factor κB(NF-κB)and Caspase-1 in peripheral blood mononuclear cells in patients with recur-rent spontaneous abortion(RSA)and reproductive tract infection(RTI),and the relationship between above inde-xes and pregnancy outcome.METHODS A total of 136 patients with RSA and RTI who were admitted to Nanyang First People's Hospital from Mar.2021 to Apr.2024 were selected as the study group,70 patients with RSA but without RTI during the same period were selected as the control group,and those patients with RSA and RTI who were pregnant again were divided into the continued pregnancy group and the abortion group based on their preg-nancy outcomes.The levels of NLRP,NF-κB and caspase-1 in peripheral blood mononuclear cells were compared between the study group and the control group,Multivariate logistic regression analysis was used to identify risk factors for adverse pregnancy outcomes in patients with RSA and RTI.Receiver's operating characteristic(ROC)curves were used to evaluate the value of NLRP,NF-κB,and Caspase-1 in peripheral blood mononuclear cells in predicting pregnancy outcomes of patients with RSA and RTI.RESULTS The levels of NLRP,NF-κB and caspase-1 in the study group were(1.93±0.49),(1.82±0.41)and(2.23±0.41)respectively,which were higher than those in the control group(P＜0.05).The proportion of abortion in the study group was 39.79％,which was higher than that in the control group(P=0.036).Pre-pregnancy body mass index(BMI)and the levels of glycated hemoglobin,triacylglycerol,NLRP,NF-κB and Caspase-1 in the abortion group were higher than those in the continued pregnancy group.Multivariate logistic regression analysis showed that NLRP3(OR=4.721,95％CI:1.336-16.680,P=0.016),NF-κB(OR=4.669,95％CI:1.495-14.58,P=0.008),caspase-1(OR=4.358,95％CI:1.260-15.070,P=0.023)and pre-pregnancy BMI(OR=2.927,95％CI:1.280-6.693,P=0.011)were risk factors affecting pregnancy outcomes of patients with RSA and RTI(P＜0.05).ROC curves indicated that the area under the curve(AUC)of NLRP,NF-κB and Caspase-1 for pregnancy outcome in patients with RSA combined with RTI was 0.846,0.885 and 0.938.CONCLUSION The NLRP,NF-κB and Caspase-1 in peripheral blood mononuclear cells is highly expressed in patients with RSA and RTI,and the high expression of the above indicators is closely related to the adverse pregnancy of patients,which can be used as a predictor of pregnancy outcomes in patients with RSA and RTI.

Objective Based on the interventional operating room,the nursing quality evaluation index system was con-structed under the background of medical union and empirical analysis was conducted,so as to provide support and basis for accu-rate and efficient evaluation of nursing quality in interventional operating room.Methods From July to September 2024,based on evidence-based methods,the relevant literature was retrieved and evaluated,and the structure-process-outcome theory was taken as the basic framework,and the relevant nursing quality indicators were preliminarily drawn up in interventional operating rooms.In October 2024,a total of 28 experts were selected to conduct expert letter consultation(2 rounds)with Delphi method,from which the indicators were revised and finally clarified,and empirical analysis was carried out.Results There were two rounds of expert consultation in this paper.The questionnaire recovery rate of the first round was 85.71％(24/28).The Cs,Ca and Cr of the first round were 0.895,0.942 and 0.919,respectively.The recovery rate of the second round questionnaire,Cs,Ca and Cr of the experts were 100.00％(24/24),0.891,0.941 and 0.916,respectively,and Kendall's W value was within 0.088-0.301(P＜0.05).The final nursing quality sensitive index system consists of 1 structure,5 process and 2 outcome inde-xes,respectively.Fifty patients undergoing interventional surgery were included before and after intervention.Empirical analysis showed that the incidence of adverse events after intervention(4.00％)was lower than that before intervention(16.00％)(P＜0.05).Conclusion The sensitive index of nursing quality based on the background of medical union is practical and scientific,and can provide practical guidance for the evaluation,continuous improvement and optimization of nursing quality in interventional operating room,and reduce the incidence of adverse events.
