		                        			ObjectiveTo evaluate a third-generation applicator template for intracavitary combined with interstitial brachytherapy (IC-ISBT) suitable for locally advanced cervical cancer, aiming to improve therapeutic outcomes. MethodsA retrospective study was conducted on patients with stage IB3-ⅣB cervical cancer treated at Sun Yat-sen University Cancer Center from January 2023 to October 2023. Magnetic resonance imaging data before and after external beam radiation therapy were collected and analyzed. According to the residual tumor after external beam radiation, high-risk clinical target volumes (HR-CTV) were delineated, based on which a third-generation IC-ISBT applicator template was designed. The dosimetric and therapeutic differences between using this applicator template (template implantation group) and traditional freehand interstitial implantation (freehand implantation group) were further compared. Statistical methods were used to analyze the data from both groups to test the efficacy and safety of the two approaches. ResultsThe third-generation applicator template could accommodate different cervical structures and optimize needle path layout. The tumor volume in the template implantation group was significantly larger than in the freehand implantation group, showing statistical differences. In terms of dosimetric coverage (V100%), the template implantation group exhibited significant statistical differences compared with the freehand implantation group, demonstrating superior dose coverage. Additionally, the third-generation template showed advantages in protecting the rectum and sigmoid colon by potentially reducing high-dose points, while there were no significant differences in bladder dosimetry between the two methods. The primary cervical lesion remission rates were similar between the two groups. ConclusionThe third-generation IC-ISBT applicator template is scientifically and rationally designed, especially for patients with larger tumor volumes and later stages. It is easy to operate, highly reproducible, and shows significant advantages in dose distribution and protection of surrounding critical organs. The template has the potential to be widely applied as a routine treatment option.

		                        			ObjectiveStarting from the etiology, pathogenesis, and treatment strategies of endometriosis and adenomyosis, to integrate and sort out the academic characteristics of contemporary renowned experts and schools in the field of traditional Chinese medicine gynecology. MethodsAccording to the systematic review of text and opinion (SrTO) process developed by the Joanna Briggs Institute (JBI) in Australia, this paper determined literature screening criteria by searching China National Knowledge Infrastructure (CNKI), VIP, Wanfang, and China Biomedical Literature Database. Information was extracted after literature screening, and quality evaluation was conducted using the JBI Narrative, Text, and Opinion Systematic Review Strict Evaluation Checklist. The JBI Narrative, Opinion, Text Evaluation, and Review Tool Summary Table was used for information synthesis, and data analysis and display were conducted in the form of text and charts. ResultsThe 146 articles related to 39 renowned experts and 19 articles related to 10 schools of thought were included. Research has found that contemporary experts and schools in traditional Chinese medicine gynecology consider blood stasis as the core pathogenesis in understanding the etiology and pathogenesis of two diseases and related infertility. Their viewpoints varied from multiple aspects such as clinical symptom characteristics, meridian circulation location, pathological product evolution, disease duration, emotional psychology, lifestyle habits, preference for food and drink, innate endowment, and acquired injury. In terms of treatment, it was advocated to divide the stage, treat according to different types, adapt to the times, integrate nature and humans, and combine multiple methods to treat comprehensively when necessary. It was also recommended to skillfully use insects, make good use of classic formulas and small prescriptions, pay attention to protecting the spleen and stomach and regulating emotions, and make good use of self-formulated empirical formulas for internal or external use. Besides, individualized long-term management of patients was also advocated. ConclusionThis study applies the SrTO process to systematically summarize the academic ideas of contemporary renowned experts and schools in traditional Chinese medicine gynecology regarding the causes, mechanisms, diagnosis, and treatments of endometriosis, providing a scientific and standardized reference for future theoretical exploration.

		                        			OBJECTIVE To investigate the current situation of pharmaceutical management in compact medical consortium of Guangdong province, and to provide decision-making basis for promoting the high-quality construction and sustainable development of the provincial medical consortium. METHODS A self-designed questionnaire was used to select 50 compact medical consortiums in Guangdong province. The survey was answered by the heads of the pharmacy department of the general hospitals. The survey covered the basic scale of the consortium, the appointment of chief pharmacists, the implementation of pharmaceutical management and pharmaceutical care homogenization within the consortium, the difficulties in promoting the homogenization, and the expected provincial support. Descriptive statistical analysis was performed on the survey results. RESULTS A total of 50 questionnaires were collected, and the effective recovery rate was 100%. There were 16 chief pharmacists (32.00%) in charge of the pharmacy department of the general hospital in the medical consortium. Thirty-seven medical consortiums (74.00%) had established a drug supply support system within the consortium, 35 medical consortiums (70.00%) had carried out pharmaceutical management and coordination work within the medical consortium, 23 medical consortiums (46.00%) had established a clinical medication guidance system, 25 medical consortiums chenwenying2016@163.com (50.00%) had established a bidirectional communication mechanism, and only 8 medical consortiums (16.00%) had developed new models of pharmaceutical care. At present, the difficulties in promoting the homogenization of pharmaceutical management and pharmaceutical care within the medical consortium were mainly found in three aspects: the wide gap in management level of each member unit, the lack and uneven level of pharmaceutical personnel, and insufficient policy support and implementation. Most medical consortiums hoped that relevant departments could promote the homogenization of pharmaceutical work by holding special training courses or special supervision. CONCLUSIONS At present, the compact medical consortium in Guangdong province has achieved initial results in the implementation of the chief pharmacist system, the homogenization of pharmaceutical management and pharmaceutical care. However, it is still necessary to improve the coverage of chief pharmacist appointments in the medical consortium, implement the homogenization of pharmaceutical management, and accelerate the homogenization process of pharmaceutical care.

		                        			Objective:To explore the effect and mechanism of c-Myc on regulating the expression of immune-related ligands in Y subtype small-cell lung cancer (SCLC) characterized by high expression of immune-related molecules.Methods:The Y subtype SCLC cell line H196 was randomly divided into the control group, c-Myc inhibitor 10058-F4 group, histone deacetylase 1 (HDAC1) inhibitor pyroxamide group, and 10058-F4 plus pyroxamide group. The co-culture system with NK-92MI cells was used to determine the effect of H196 cells on the function of natural killer (NK) cells. Western Blotting and co-immunoprecipitation assays were used to detect the effect of c-Myc on class Ⅰ HDAC, and flow cytometry was used to detect the regulatory effect of c-Mycon CD47, programmed cell death ligand 1 (PD-L1), and CD155, which are highly expressed immune checkpoints in Y subtype SCLC, and major histocompatibility complex classⅠ-related chains A and (MICA/B), which is a poorly expressed immune-activating ligand in SCLC, and the role of HDAC. Chromatin immunoprecipitation (ChIP) assay and real-time quantitative polymerase chain reaction (RT-qPCR) were used to determine the regulatory mechanism of c-Myc-HDAC1 on MICA/B expression.Results:Inhibition of c-Myc decreased the mortality of H196 cells in the co-culture system and down-regulated the expression of MICA/B. Compared with the NK+H196 group [(42.54±2.47)%], the proportion of cells killed by NK-92MI cells in the NK+H196+10058-F4 group was lower [(28.48±3.38)%, P<0.001]. The mean fluorescence intensity (MFI) of MICA/B on the cells in the 10058-F4 group (36.40±0.82) was lower than that in the control group (91.23±8.60, P<0.001). And c-Myc could bind to HDAC1, whose protein level was up-regulated by 10058-F4 while the mRNA level was not. Compared with the cells in the control group (90.10±4.91), the MFI of MICA/B on the cells in the pyroxamide group was significantly increased (145.70±5.86, P<0.001), and the MFI of MICA/B on the cells in the 10058-F4+pyroxamide group (54.60±2.88) was significantly increased compared with the cells in the 10058-F4 group (35.97±1.60, P<0.001). The percentage of MICA promoter gene fragments in the c-Myc antibody precipitation group (0.125±0.037) was significantly higher than that in the IgG group (0.000 8±0.000 3, P=0.004). MICB had a similar trend, suggesting that the c-Myc-HDAC1 complex could bind to the promoter region of MICA/B. The MFI of CD47 on the cells in the 10058-F4 group (60.07±0.21) was significantly lower than cells in the control group (70.27±1.37, P<0.001), but the MFIs of PD-L1 (13.50±0.61) and CD155 (829.70±41.19) were significantly higher than those on the cells in the control group (9.23±0.94, P<0.01; 496.00±4.36, P<0.001, respectively). Conclusions:c-Myc may promote the expression of MICA/B and CD47 in Y subtype SCLC cells by binding and inhibiting HDAC1, while it may also be involved in inhibiting the expression of PD-L1 and CD155 in SCLC cells.

		                        			Objective To screen the characteristic factors of renal impairment occurrence in the patients with hyperuricemia,and to analyze its diagnostic value and establish a diagnostic model.Methods A total of 2405 inpatients with diagnosed hyperuricemia in the Nanjing Municipal Hospital of Traditional Chinese Medi-cine,Nanjing University of Traditional Chinese Medicine from December 2018 to December 2022 were selected and divided into the kidney lesion group (n=1343) and the non-kidney lesion group (n=1062) according to eGFR.The characteristic factors of hyperuricemia caused renal impairment were screened and analyzed by Lasso and logistic regression and the diagnostic model was constructed.The diagnostic value of characteristic factors and diagnostic model were evaluated by the receiver operating characteristic (ROC) curve,and the change rule between the characteristic factors and the results was found by the restricted cubic splines (RCS) fitting.Results The age,uric acid (UA),cystatin-C (Cys-C) and retinol-binding protein (RBP) were the characteristic factors of hyperuricemia caused renal impairment.The combined diagnostic model:logit (P)=-8.70+0.602×age (10 years old)+0.033×UA (10 μmol/L)+0.277×Cys-C (0.1 mg/L)+0.189×RBP (10 mg/L),the area under the ROC curve (AUC) of the combined diagnosis model was 0.893 (95%CI:0.880-0.905).For every 10 μmol/L increase in blood UA,the risk of renal impairment occurrence in hyperurice-mia was increased by 3%;for every 10 years increase in age,the risk of renal impairment occurrence in hyperu-ricemia was increased by 83%;for every 10 mg/L increase in RBP,the risk of kidney damage occurrence of re-nal impairment in hyperuricemia was increased by 21%;for every 0.1 mg/L increase in Cys-C,the risk of re-nal impairment occurrence in hyperuricemia was increased by 32%.Conclusion The combined diagnostic model for whether the renal impairment in the patients with hyperuricemia occurring has good diagnostic val-ue,and Cys-C deserves more attention.
