OBJECTIVE: To investigate the current status of clinical genetics specialization development and the diagnostic and therapeutic capabilities for hereditary diseases across medical institutions in Shanghai, and to assess the necessity and feasibility of establishing training bases for clinical genetics specialists. METHODS: By employing a cross-sectional survey design, the Clinical Genetics Committee of Shanghai Medical Association has conducted questionnaire surveys from March to April 2025 across 54 healthcare institutions in Shanghai (including 33 tertiary hospitals and 21 secondary hospitals). The survey involved administrative departments and medical personnel from 15 clinical specialties. The survey has covered current genetic disease diagnosis and treatment practices, relevant and specialised disease types, genetic department establishment, testing capabilities, personnel teams, and training requirements. RESULTS: The results revealed that 78.0% of clinical departments surveyed had treated patients with hereditary disorders. Shanghai possesses diagnostic and therapeutic expertise for over 95% of hereditary diseases listed in its rare disease catalogue, reflecting both the practical clinical demand for such conditions and the city's overall diagnostic and therapeutic strengths in this field. Nevertheless, significant disparities exist in the development of genetics departments across different tiers of healthcare institutions. Resources for genetic testing capabilities (including molecular, cellular, and biochemical testing) are also unevenly distributed across different tiers of hospitals. The survey further revealed that only 26.0% of departments believe that their current physician structure fully meets the diagnostic and treatment demands. Over 90% of departments consider standard training for clinical genetic specialists necessary, with 74.0% expressing willingness to participate in establishing training bases. Based on above findings and thorough deliberation, the Clinical Genetics Committee of the Shanghai Medical Association proposes advancing specialist training and discipline development through establishing a standard training system. The committee has drafted a three-year training protocol featuring a "joint training"-centered model, recommending a pilot-first, dynamically optimized strategy for steadily advancing training base development. CONCLUSION Shanghai faces substantial demand for genetic disease diagnosis and treatment, yet exhibits shortcomings in clinical genetics specialization development, resource allocation, and talent pipeline cultivation. To establish a standard training system holds significant practical importance and is underpinned by a broad demand.

ObjectiveTo investigate the correlation between neutrophil-to-lymphocyte ratio （NLR）， platelet-to-lymphocyte ratio （PLR）， systemic immune-inflammation index （SII） and the severity of intrauterine adhesions （IUA）. MethodsThe retrospective study included 380 patients who underwent transcervical resection of adhesions （TCRA） from December 2019 to March 2025. Based on the American Fertility Society （AFS） classification， patients were divided into mild （n=61）， moderate （n=225）， and severe （n=94） groups. NLR， PLR， and SII were calculated from preoperative blood tests. Statistical analyses included Kruskal-Wallis test and ordinal Logistic regression. ResultsNLR， PLR， and SII were significantly higher in the severe IUA group compared to the mild group （P<0.05）， with SII showing the strongest predictive ability （OR=1.004， P=0.001）. The number of intrauterine procedures was an independent risk factor （OR=1.27/level， P=0.016）. The predictive model ［Logit（P）=-0.676+0.241×operation times+0.004×SII］ effectively identified severe IUA cases. ConclusionInflammatory markers （particularly SII） are correlated with IUA severity and may serve as non-invasive tools for clinical assessment.

ObjectiveTo evaluate the pregnancy outcomes of assisted reproductive technology （ART） in women with a history of thyroid cancer who retained fertility intentions after completing cancer treatment. MethodsA retrospective analysis was performed on 61 patients with a history of thyroid cancer who underwent in vitro fertilization/intracytoplasmic sperm microinjection and embryo transfer （IVF/ICSI-ET）. These patients were included as the case group. A total of 122 non-cancer patients who received ART during the same period were selected as the control group using 1∶2 matching based on age and oocyte retrieval time. Baseline characteristics， outcomes of the first ART cycle， and cumulative pregnancy outcomes were compared between the two groups. ResultsThere was no significant difference in the basic data， the total amount of gonadotropin （Gn） and the days of use between the case group and the control group （P>0.05）. However， the case group had significantly fewer retrieved oocytes， mature oocytes （MII）， lower fertilization and cleavage rates， and fewer transferable and high-quality embryos， as well as fewer embryos transferred during the first cycle （P < 0.05）. However， there was no significant difference in the rate of first embryo implantation and first clinical pregnancy between the two groups （P>0.05）. In the analysis of cumulative outcomes， the two groups did not show statistically significant differences in the cumulative pregnancy rate， clinical pregnancy rate per transfer cycle， the number of oocyte retrieval cycles required per live birth， the number of embryo transfer cycles required per live birth， and the number of embryos used for each live birth （P>0.05）. However， the cumulative live birth rate was significantly lower in the case group compared to the control group （P=0.005）. ConclusionAfter treatment for thyroid cancer， when ART is used to help pregnant women， the pregnancy outcome is comparable to that of women without tumors. Individualized reproductive management and timely fertility preservation strategies are recommended to optimize reproductive outcomes in this population.

Abstract The prevention and control of myopia in Chinese children and adolescents has become a major public health issue. While maintaining increased outdoor activity as a cornerstone intervention, there is an urgent need to explore new complementary approaches that can be effectively implemented in both indoor and outdoor settings. In recent years, environmental spatial frequency has gained increasing attention as one of the key environmental factors influencing the development and progression of myopia. Both animal studies and human research have confirmed that indoor environments lacking mid to high spatial frequency components, often characterized as "visually impoverished", can promote axial elongation and myopia through mechanisms such as disruption of retinal neural signaling, impaired accommodative function, and altered expression of related molecules. Based on the scientific consensus, it is recommended that "enriching of environmental spatial frequency" should be integrated into the myopia prevention and control framework. Following the principles of schoolled organization, family cooperation, community involvement, and student participation, specific measures are put forward in three areas：optimizing school visual settings, improving home spatial environments, and promoting healthy visual behavior. The aim is to create "visually friendly" indoor environments as an important supplement to outdoor activity, thereby providing a novel perspective and strategy for comprehensively advancing myopia prevention and control among children and adolescents.

Objective:To investigate the longitudinal trajectories of symptom clusters in elderly patients with laparoscopic surgery for colon cancer, and explore the predictive factors for each trajectories subgroup.Methods:Using a longitudinal survey, elderly patients with laparoscopic surgery for colon cancer patients from Shanxi Bethune Hospital from January 2021 to January 2024 were collected by convenient sampling method. The Chinese Version of the MD Anderson Symptom Inventory Gastrointestinal Cancer Module was used to conduct follow-up surveys of the selected patients at 2 weeks, 1 month, 3 months and 6 months after surgery. The symptom cluster was extracted by exploratory factor analysis, and the latent category growth model was conducted to identify the trajectory subgroups of each symptom cluster, the predictive factors of each trajectory subgroup was analyzed by multiple Logistic regression analysis.Results:A total of 118 cases were concluded in the present study, there were 69 males and 49 females with an age of (74.85 ± 3.29) years old. There were 4 symptom clusters after surgery, which were named as energy deficit symptom cluster, digestive tract symptom cluster, sleep mental symptom cluster, and psychological fatigue symptom cluster, the variance contribution rates were respectively 62.486%, 71.209%, 73.937%, 63.476%. The results from latent class growth model showed that there were 3 trajectory subgroups in the symptom cluster: high level-slow decline group accounted for 33.0% (39/118), moderate level-stable decline group accounted for 39.0% (46/118), low level-rapid decline group accounted for 28.0% (33/118). College education or above tends to developed into low level-rapid decline group ( OR=0.365, 95% CI 0.083-0.603, P<0.05), while patients undergoing traditional laparoscopic surgery ( OR=3.679, 95% CI 1.297-4.432, P<0.05) and primary tumor stages of Ⅲ-Ⅳ were more likely to developed into high level-slow decline group ( OR=0.333, 95% CI 0.120-0.920, P<0.05). Conclusions:There are 4 symptom clusters in elderly patients with laparoscopic surgery for colon cancer, and the characteristics of postoperative symptom cluster changes demonstrate significant heterogeneity, medical staff should pay attention to the management of symptom clusters trajectory categories, dynamically adjust intervention plans to improve nursing quality.

Objective To investigate a cluster of healthcare-associated infection(HAI)of carbapenem-resistant Klebsiella pneumoniae(CRKP)in intensive care unit(ICU)of a traditional Chinese medicine hospital,and provide evidence for the prevention and control of multidrug-resistant organisms in hospitals.Methods From January to Ju-ly 2023,multiple cases of CRKP infection in the ICU of a traditional Chinese medicine hospital occurred,surpassing the number in the same period of previous years.Through collection of patients'clinical information,epidemiologi-cal investigation and environmental hygiene monitoring,the isolated CRKP strains were identified by pulsed-field gel electrophoresis(PFGE),possible causes of transmission were found out,and corresponding control measures were taken.Results During the study period,a total of 13 patients were confirmed to have developed CRKP infection,mainly respiratory tract infection,bloodstream infection,and abdominal infection.Environmental monitoring showed that only 2 out of 131 environmental object surfaces specimens and staff's hand specimens tested positive for CRKP.PFGE identification showed that the 2 CRKP strains isolated from the sink specimens were highly homolo-gous to the strains isolated from 2 recently admitted patients.Some strains isolated from patients were highly ho-mologous,indicating a possibility of cross transmission.Conclusion CRKP is prone to be cross-transmission among ICU patients and contaminates the environment.Early warning and investigation should be conducted to prevent the occurrence of HAI outbreaks.

Objective To evaluate the protective effect of Schistosoma japonicum cystatin(rSj-Cystatin)in a mouse mode of"two-hit"sepsis.Methods Sixty male C57BL/6 mice randomized equally into sham-operated group,protein group,"two-hit"modeling group,and protein intervention group.In the former two groups,the mice received an intraperitoneal injection of 100 μL PBS followed by exposure of the cecum and then by intraperitoneal injection of 100 μL PBS or 25 μg rSj-Cystatin 30 min later;In the latter two groups,100 μL PBS containing LPS(5 mg/kg)was injected intraperitoneally 24 h before cecal ligation and puncture(CLP),and 100 μL PBS or 25 μg rSj-Cystatin were injected 30 min after CLP.At 12 h after rSj-Cystatin treatment,6 mice from each group were sacrificed for detection of TNF-α,IL-6,IL-10,TGF-β,iNOS and Arg-1 in the serum,spleen,liver,lung and kidney tissues using ELISA,for examinations of liver,lung and kidney pathologies with HE staining,and for analysis of CD3+CD4+CD25+Foxp3+T cell percentage in the spleen using flow cytometry.The remaining mice were observed for general condition and 72-h survival.Results The 72-h survival rates in the 4 groups were 100％,100％,0％and 20％,respectively,showing significant differences between the latter two groups.The mouse models of"two-hit"sepsis exhibited obvious tissue pathologies and significant elevations of TNF-α and IL-6 in both the serum and tissue homogenate,which were significantly ameliorated by rSj-Cystatin treatment.Treatment with rSj-Cystatin also increased IL-10 and TGF-β levels and spleen CD3+CD4+CD25+Foxp3+T cell percentage.The septic mouse models also showed increased iNOS levels in all the detected tissues and a decreased Arg-1 level in the kidney,and these changes were obviously improved by rSj-Cystatin treatment.Conclusion rSj-Cystatin has a protective effect against"two-hit"sepsis in mice by regulating the inflammatory microenvironment.

Objective To determine the effect of baicalein on high glucose-induced cardiac fibro-blast pyroptosis based on the nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)/cysteinyl aspartate-specific proteinase-1(Caspase-1)/gasdermin D(GSDMD)pathway.Methods Rat cardiac fibroblasts were grouped into control,high glucose group,low-,medium-and high-dose baicalein(H-,M-and L-baicalein)groups,and H-baicalein+NLRP3 agonist(BMS-986299)group.Except for the control group,all other groups were cultured in DMEM medium containing 40 mmol/L glucose,then 12.5,25 and 50 μmol/L baicalein was added into the medium correspondingly,and 1 μmol/L BMS-986299 was used to treat the H-baicalein+NLRP3 agonist group.Lactate dehydrogenase(LDH)cytotoxicity assay were employed to detect cell cytotoxicity.qRT-PCR and Western blotting were performed to determine the expression of NLRP3,Caspase-1,and GSDMD at mRNA and protein levels.Results High glucose treatment induced more EdU positive cells,higher pyroptotic rate,stronger cytotoxicity,higher Col-Ⅰ and Col-Ⅲ contents,and enhanced mRNA and protein levels of NLRP3,Caspase-1 and GSDMD in comparison to the control group(P＜0.05).The H-baicalein+NLRP3 agonist group had more EdU positive cells(26.85±2.95 cells vs 15.43±1.82 cells,P＜0.05),higher pyroptotic rate[(33.45±4.02)％vs(17.34±2.15)％,P＜0.05],stronger cytotoxicity[(27.94±2.93)％vs(14.13±1.87)％,P＜0.05],and increased contents of Col-Ⅰ(107.58±13.39 ng/ml vs 58.73±8.36 ng/ml,P＜0.05)and Col-Ⅲ(118.43±13.95 ng/ml vs 68.74±8.57 ng/ml,P＜0.05),and enhanced expression of NLRP3,Caspase-1 and GSDMD at both mRNA and protein levels(P＜0.05)when compared with the H-baicalein group.Conclusion Baicalein inhibits high glucose-induced cardiac fibroblast pyroptosis by suppressing NLRP3/Caspase-1/GSDMD pathway.

Objective:To observe changes in intestinal flora in children with anorexia and the effects of pediatric Tuina(Chinese therapeutic massage)on their intestinal flora,and to explore the relationship between alterations in intestinal flora and anorexia,as well as the therapeutic mechanisms of pediatric Tuina in treating children with anorexia.Methods:A total of 60 healthy children who underwent physical examinations were recruited as the blank group.One hundred and twenty children with anorexia were randomly divided into a Tuina group and a medication group,with 60 children in each group,according to the random number table method.The blank group received no intervention;the Tuina group was treated with pediatric Tuina therapy;the medication group was treated with Jian Wei Xiao Shi(stomach-invigorating and digestion-promoting)tablets.Both groups underwent continuous treatment for 7 d as one course,with a 1-day rest period between courses,for a total of 4 courses.Fecal samples were collected from the three groups.The intestinal flora was detected using the 16S rDNA method.Results:Before treatment,compared to the blank group,the abundance of Firmicutes in the Tuina and medication groups was significantly lower(P<0.05).After treatment,the abundance of Firmicutes in the Tuina group was significantly increased compared to before treatment(P<0.05),with no significant difference compared to the blank group(P>0.05);in the medication group,there was a trend of increased abundance of Firmicutes,but there was no significant difference compared to that before treatment in the same group(P>0.05),and the difference compared to the blank group remained significant(P<0.05).Before treatment,compared to the blank group,the abundance of Faecalibacterium prausnitzii(F.prausnitzii)in the Tuina and medication groups was significantly lower(P<0.05).After treatment,the abundance of F.prausnitzii in the Tuina group was significantly increased compared to before treatment(P<0.05),with no significant difference compared to the blank group(P>0.05);in the medication group,there was a trend of increased abundance of F.prausnitzii,but no significant difference was showed compared to before treatment in the same group(P>0.05),and the differences compared to the blank and Tuina groups were significant(P<0.05).Before treatment,compared to the blank group,the abundance of Eubacterium in the Tuina and medication groups was significantly lower(P<0.05);after treatment,the abundance of Eubacterium in both Tuina and medication groups was significantly increased compared to that before treatment(P<0.05),with no significant difference compared to the blank group(P>0.05).Before treatment,compared to the blank group,the abundance of Roseburia in the Tuina and medication groups was significantly lower(P<0.05);after treatment,the abundance of Roseburia in both Tuina and medication groups was significantly increased compared to that before treatment(P<0.05),with no significant difference compared to the blank group(P>0.05).Conclusion:The reduction of beneficial intestinal flora may be involved in the pathogenesis of pediatric anorexia.Pediatric Tuina can promote the recovery of intestinal flora balance by increasing the abundance of beneficial flora.

Objective To establish a risk prediction model of continuous renal replacement therapy(CRRT)withdrawal failure in patients with infectious shock complicating acute kidney injury(AKI)based on the decision tree algorithm,and to explore the influencing factors of CRRT withdrawal failure in patients with infectious shock complicating AKI.Methods 220 patients with infectious shock complicating AKI admitted to our hospital from May 2020 to May 2023 were retrospectively analyzed,and divided into success group and failure group according to the success or failure of the withdrawal,univariate and multivariate Logistic regression analysis were used to screen risk factors of CRRT withdrawal failure in patients with septic shock complicated with AKI,C-reactive protein/albumin(CRP/ALB)at admission and sepsis-related organ failure assessment(SOFA)score at withdrawal,acute physiology and chronic health evaluation(APACHE Ⅱ)score,N-terminal B-type natriuretic peptide(NT-proBNP)level at the beginning of CRRT,mean arterial pressure(MAP)grading,urine volume after withdrawal,and serum creatinine(Scr)level after withdrawal were taken into constructing a decision tree model and validating the model efficacy.Results In this study,there were 41.82％of patients failed to withdrawal.Combination of univariate and multivariate Logistic regression analysis showed that SOFA score at withdrawal,APACHE Ⅱ scores,urine volume after withdrawal,Scr level after withdrawal,NT-proBNP at the beginning of CRRT,and MAP grading,CRP/ALB at the time of admission were an independent risk factor for CRRT withdrawal failure in patients with septic shock complicated with AKI(P＜0.05).The results showed that the higher CRP/ALB was the most important influencing factor on the failure of CRRT evacuation in patients with infectious shock complicating AKI,and the area under the receiver operating characteristic curve was 0.965.Conclusion The decision tree model constructed by CRP/ALB at admission,SOFA score at withdrawal,urine volume after withdrawal,Scr level after withdrawal,APACHE Ⅱ score,and MAP grading has a better predictive efficacy of CRRT withdrawal failure in patients with infectious shock complicating AKI,which is a guideline for patients'prognostic assessment.
