In order to further standardize the vaccination of kidney transplant candidates and recipients in China, the Branch of Organ Transplantation of Chinese Medical Association has organized experts in kidney transplantation and infectious diseases. Based on the "Vaccination of Solid Organ Transplant Candidates and Recipients: Guidelines from the American Society of Transplantation Infectious Diseases Community of Practice", and in combination with the clinical reality of infectious diseases and vaccination after organ transplantation in China, as well as referring to relevant recommendations from home and abroad in recent years, these guidelines are formulated from aspects such as epidemiology, types of vaccines, vaccination principles, target population, and specific vaccine administration. The "Guidelines for Vaccination of Kidney Transplant Candidates and Recipients in China" aims to provide theoretical reference for medical workers in the field of kidney transplantation in China, regarding the vaccination of kidney transplant candidates and recipients. It is expected to better guide the vaccination of kidney transplant candidates and recipients, reduce the risk of postoperative infection, and improve survival outcomes.

Objective: To analyze the status and trends of the disease burden of periodontal disease among women of reproductive age (15-49 years) in China from 1990 to 2021, and to provide a reference for the development of periodontal disease prevention and control strategies for women of reproductive age. Methods: Using the global burden of disease (GBD) data from 1990 to 2021, this study investigated the periodontal disease burden among women of reproductive age, including prevalence, incidence, disability-adjusted life years (DALYs), DALY rates, and their corresponding standardized indicators. Joinpoint 5.2.0.0 software was used for time trend analysis of DALYs, age-specific DALY rates, and annual average percentage change (AAPC) values. A log-linear regression model was used to test trends for DALYs and DALY rates. Results: Compared with 1990, the prevalence and incidence of periodontal disease among Chinese women in 2021 increased by 45.67% (per 100,000 people) and 29.29% (per 100,000 people), respectively. The distribution of periodontal disease among women (15-49 years) showed a continuous and rapid upward trend, with the growth rate increasing rapidly with age. The number of cases increased the fastest in the 45-49 age group, and the prevalence increased the fastest in the 35-44 age group. The incidence of periodontal disease continued to rise with age, with the fastest increase in the 35-44 age group among women of reproductive age. The Joinpoint regression model results showed that periodontal disease led to an expanding trend in the disease burden among women of reproductive age in China, with an AAPC of DALYs = 1.20% and an AAPC of DALY rate = 1.25% (P<0.001). Conclusion The periodontal disease burden among Chinese women aged 15-49 years showed a gradually increasing trend from 1990 to 2021.

Most patients with pancreatic cancer are already in the locally advanced or metastatic stage at initial diagnosis. While systemic chemotherapy provides clinical benefits for those with mid-to-late-stage pancreatic cancer, its efficacy is often limited by patient tolerance. In response to the dual clinical demands of robust antitumor activity and high targeting specificity, antibody-drug conjugate (ADC) has emerged as a promising solution. By conjugating highly selective monoclonal antibodies with potent cytotoxic small-molecule drugs, ADC achieves precise tumor-targeting while minimizing damage to healthy tissues, which thereby improves treatment tolerance. However, due to the complex pathological features of pancreatic cancer, no ADC has yet been approved for clinical use for this disease. A comprehensive evaluation of factors including ADC-specific targets, payload selection, antibody-drug linkage strategies, drug delivery mechanisms, tissue distribution variability, and tumor heterogeneity will be crucial to advancing the clinical translation of ADC for pancreatic cancer treatment.

Gastric cancer is one of the most common malignant tumors worldwide,with high morbidity and mortality rates.This malignancy poses a grave threat to human life and health.Its early onset symptoms are not typical,and many patients are diagnosed in the middle and late stages;multidisciplinary comprehensive treatment remains the primary treatment for patients with advanced and unresectable gastric cancer.Comprehensive surgery is typically performed for patients with gastric cancer who are eligible for surgery.Preoperative arterial infu-sion chemotherapy is gradually receiving attention as a novel treatment method.Compared with traditional chemotherapy,it has the ad-vantages of higher efficiency,fewer side effects,and a higher surgical resection rate in later stages.It has been gradually applied in clinical practice and has achieved certain results.This article discusses the application and development of arterial infusion chemotherapy in the neoadjuvant therapy for gastric cancer.

Objective To design a storage device for lymph node specimens of gynecological malignant tumors and to evaluate its application effect.Methods The specimen depository is composed of 3 parts,including storage frame,partition plate and marking plate.391 patients with gynecological malignant tumor surgeries requiring collection of retroperitoneal lymph nodes were selected in the operating room of a tertiary A hospital in Zhejiang Province from January to December 2022 in accordance with the operation schedule.They were randomly divided into an experimental group(n=196)and a control group(n=195).Patients in the experimental group used a newly developed storage device,while the control group was with traditional device.The incidence of additional verification specimens by doctors,the average time for disposing of lymph node specimens,and the job satisfaction survey of doctors and nurses were compared.Results Within a period of 12 months after utilizing this easily recognizable specimen storage device,the additional verification rate in the experimental group was 10.62％compared with the rate of 72.48％in the control group.The average time of disposing lymph node specimens was reduced from(8.3±0.9)to(5.2±0.3)minutes.Doctors and nurses in the experimental group reported a higher level of satisfaction for the specimen storage device(P＜0.05).Conclusion Utilizing the newly designed specimen storage device can help medical staff to alleviate their workload,enhance their work efficiency,raise their job satisfaction,and ensure the accuracy of pathological results.

Objective To investigate whether modification with IL-21 and CCL19 enhances killing and tumor-infiltrating efficiency of NKP30 CAR-T cells in lung cancer.Methods The modified IL-21-CCL19 NKP30 CAR-T cells expressing IL-21 and CCL19 fusion gene was constructed based on NKP30 CAR-T cells and stimulated with CD3CD28 antibodies and IL-2.The immunophenotype and migration of the cells in the presence of IL-21 were investigated using flow cytometry and migration experiments.Lactate dehydrogenase(LDH)release and sphere formation assays were used to assess the killing and infiltration capabilities of CAR-T cells,and the secretion levels of IFN-γ,IL-21 and CCL19 were determined with enzyme-linked immunospot assay(ELISPOT)and ELISA.A zebrafish model bearing HCG-27 cell xenograft was established by microinjection of the tumor cells into the yolk sac followed 24 h later by injection of the immune cells at the same site,and the fluorescence signals were captured using a fluorescent microscopy.Results The NKP30 ligand B7H6,which was almost undetectable in normal tissues and blood cells,was highly expressed(over 90%)in lung cancer cells.Compared with NKP30 CAR-T cells and conventional T cells,IL-21-CCL19 NKP30 CAR-T cells exhibited stronger proliferative and migration capabilities with the formation of central memory T cells.The reduced expressions of CTLA4 and PD1 in the constructed cells resulted in enhanced killing efficiency against lung cancer cells accompanied by significantly increased production of IFN-γ,IL-21 and CCL19.In the zebrafish models,CAR-T cells exhibited stronger cytotoxicity and proliferative abilities than typical T cells,but these differences were not statistically significant between the two CAR-T cells.Conclusion Modification of NKP30 CAR-T cells with IL-21 and CCL19 facilitates their access into solid tumors for more effective tumor cell killing while producing a large number of memory T cells.

Cyperi Rhizoma is a common Chinese medicine in clinical practice， which has a long history of processing. In order to sort out the process of its processing， starting with the angle of processing excipients， the historical evolution and developmental venation of Cyperi Rhizoma processing were analyzed and summarized by consulting relevant literature of ancient medical records and modern codes. After combing the ancient and modern literature， it was found that there were many processing methods of Cyperi Rhizoma， the processing methods without auxiliary materials included frying， boiling， steaming and so on， and the adding auxiliary materials included vinegar， ginger， salt， multiple excipients， etc. However， with the evolution of history， some characteristic excipients have gradually disappeared， while vinegar-processed products are mainly used in modern times. Meanwhile， processing methods of Cyperi Rhizoma are well documented in various processing standards， the phenomenon of multiple methods adopted in one place and different methods in different places exists， which lacks unified quality standards and leads to uneven quality of Cyperi Rhizoma decoction pieces， which may even affect the safety and effectiveness of its clinical medication. Based on this， the problems existing in the processing research of Cyperi Rhizoma were analyzed in this paper， and made an outlook on the inheritance of the ancient processing methods and the quality standard improvement of the decoction pieces， in order to provide important literature evidence and theoretical support for the study of processing process and mechanism of Cyperi Rhizoma.

Objective:To investigate the expressions of MUC1, MUC4, MUC5AC and MUC16 in patients with first diagnosis of dry eye and their correlation with dry eye symptoms and signs.Methods:A cross-sectional study was conducted.Sixty-nine dry eye patients (69 eyes) as dry eye group and 40 normal volunteers (40 eyes) as normal control group were recruited in Xiamen Eye Center of Xiamen University, Beijing Tongren Hospital, West China Hospital of Sichuan University and Shanghai Puotuo District Center Hospital from December 2016 to May 2018.Symptoms were evaluated by Chinese dry eye questionnaire, Ocular Surface Disease Index (OSDI) and Dry Eye-Related Quality-of-Life Score Questionnaire (DEQS). Signs were assessed by tear film breakup time (TBUT), keratoconjunctival fluorescein sodium staining, and Schirmer I test.Conjunctival cells were collected by conjunctival impression cytology.The expression levels of MUC1, MUC4, MUC5AC and MUC16 mRNA in the two groups were determined by real-time fluorescence quantitative PCR.The correlation between the mRNA levels of conjunctival mucins and dry eye symptoms and signs were analyzed by Spearman correlation analysis.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committees of Xiamen Eye Center of Xiamen University (No.2017003), Beijing Tongren Hospital, Capital Medical University (No.TREC2016-29), West China Hospital of Sichuan University (No.2016310) and Shanghai Puotuo District Center Hospital (No.PTEC-A-2016-18-1). Written informed consent was obtained from each subject before any medical examination.Results:The expression levels of MUC1 and MUC16 mRNA in dry eye patients were 3.277(0.568, 5.790) and 1.815(1.048, 3.694), which were higher than 1.055(0.550, 2.010) and 1.024(0.541, 1.965) in normal control group (Z=819.00, P=0.008; Z=861.00, P=0.002). According to OSDI scores, MUC1 was mainly increased to 3.277(1.161, 6.226) in mild to moderate (12-32 points) dry eye patients (Z=9.04, P=0.029), and MUC16 was mainly increased to 1.968(1.074, 3.726) in severe (>32 points) dry eye patients (Z=12.24, P=0.007). MUC1 expression was positively correlated with TBUT, and was negatively correlated with corneal staining scoring and keratoconjunctival staining scoring ( r s=0.270, P=0.025; r s=-0.331, P=0.006; r s=-0.325, P=0.007). MUC16 expression was positively correlated with TBUT, and was negatively correlated with blurred vision scoring, symptom exacerbation scoring during reading, impact scoring of driving at night, impact scoring of computer and impact scoring of TV use ( r s=0.249, P=0.039; r s=-0.359, P=0.047; r s=-0.370, P=0.034; r s=-0.558, P=0.016; r s=-0.498, P=0.006; rs=-0.515, P=0.002). Conclusions:The gene expressions of MUC1 and MUC16 are higher in conjunctiva of dry eye patients.MUC1 mRNA expression is related to patients' signs.MUC16 mRNA expression is related to the quality of life of patients.
