OBJECTIVE To investigate the clinical characteristics of euglycemic diabetic ketoacidosis （euDKA） induced by empagliflozin， and provide references for safe medication. METHODS Case reports of euDKA induced by empagliflozin were retrieved and analyzed from PubMed， Web of Science， CNKI， and Wanfang Data. The Naranjo’s scale was adopted to assess the causal relationship between empagliflozin and euDKA. RESULTS A total of 29 patients were enrolled， including 16 males and 13 females，with a median age of 58 years. All patients were diagnosed with type 2 diabetes mellitus； 22 patients had at least one comorbidity. The median time to euDKA onset was 60 days after administration， and 7 cases occurred within 2 weeks of treatment. Perioperative periods，fasting，and low-carbohydrate or ketogenic diets were the main predisposing factors. Common presentations included nausea，vomiting， fatigue， tachypnea，and tachycardia. The causal relationship between empagliflozin and euDKA was assessed as “probable” in all cases. According to adverse reaction severity grading， 13 cases were grade 3 （severe） and 16 cases were grade 4 （life-threatening）. All patients discontinued empagliflozin and recovered after corresponding treatment. CONCLUSIONS euDKA is a serious adverse reaction to empagliflozin， which mostly occurs early in treatment. Perioperative periods， fasting， and ketogenic diets are prone to induce euDKA. Elderly patients and those with comorbidities are at higher risk. Risk assessment should be conducted before clinical administration； blood ketones and acid-base monitoring should be strengthened in the early medication period； withhold the drug before elective surgery， avoid prolonged fasting；upon diagnosis， discontinue empagliflozin and initiate intravenous insulin， provide fluid resuscitation promptly， and use other treatments to improve patient prognosis.

Lianggesan was first recorded in Taiping Huimin Heji Jufang， which was composed of Rhei Radix et Rhizoma， Natrii Sulfas， Gardeniae Fructus， Forsythiae Fructus， Scutellariae Radix， Glycyrrhizae Radix et Rhizoma（GRR）， Menthae Haplocalycis Herba， Lophatheri Herba and Mel. It was clinically applied to treat fire-heat syndrome in the upper and middle Jiao， and the curative effect was positive. In this study， the bibliometric method was used to conduct a detailed textual research on the formula name， medicinal composition， dosage evolution， origin and processing， functional indications and other aspects of Lianggesan. Research revealed that Lianggesan has six other names， such as Lianqiao Yinzi， Lianqiao Jiedusan， Jufang Lianggesan， Jiegu Lianggesan， Hejian Lianggesan and Qingji Lianggesan. Based on the edition of Taiping Huimin Heji Jufang， an analysis of the evolution of its formula composition revealed that the missing Chinese medicines were predominantly bamboo leaves and honey， while the added Chinese medicines were primarily supplements introduced to address changes in disease manifestations. After textual research， the dosage for one dose of Lianggesan from Taiping Huimin Heji Jufang was as follows：826 g of Rhei Radix et Rhizoma， 826 g of Natrii Sulfas， 826 g of GRR， 413 g of Gardeniae Fructus， 413 g of Menthae Haplocalycis Herba， 413 g of Scutellariae Radix， and 1652 g of Forsythiae Fructus. Decocting method was as following：Grinding the Chinese medicines into coarse powder（2-4 mm）， taking 8.16 g per dose， adding 300 mL of water， along with 2 g of Lophatheri Herba and 5 g of Mel， and decocting to 140 mL. The residue was removed and taken warmly 30 min after meals. It was recommended to take it three times daily until improvement was achieved. The origins of the 9 Chinese medicines were consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. Except for GRR， which required single frying（stir-frying）， the remaining medicines were all raw products. The description of the function of this formula in ancient books was summarized as purging fire and promoting bowel movements， clearing heat from the upper body and purging the lower body， and the main syndromes included facial redness， tongue swelling， red eyes， etc. In modern applications， the formula is primarily used for respiratory and digestive system diseases， including acute lung injury， chronic obstructive pulmonary disease， herpetic angina and aphthous stomatitis， covering 142 types of diseases. In summary， this paper can provide a basis for further research and development of Lianggesan through the literature review and key information combing.

Chronic pain, frequently comorbid with neuropsychiatric disorders, significantly impairs patients' quality of life and functional capacity. Accumulating evidence implicates the chemokine CCL2 and its receptor CCR2 as key players in chronic pain pathogenesis. This review examines the regulatory mechanisms of the CCL2/CCR2 axis in chronic pain processing at three hierarchical levels: (1) Peripheral Sensitization: CCL2/CCR2 modulates TRPV1, Nav1.8, and HCN2 channels to increase neuronal excitability and CGRP signaling and calcium-dependent exocytosis in peripheral nociceptors to transmit pain. (2) Spinal Cord Central Sensitization: CCL2/CCR2 contributes to NMDAR-dependent plasticity, glial activation, GABAergic disinhibition, and opioid receptor desensitization. (3) Supraspinal Central Networks: CCL2/CCR2 signaling axis mediates the comorbidity mechanisms of pain with anxiety and cognitive impairment within brain regions, including the ACC, CeA, NAc, and hippocampus, and it also increases pain sensitization through the descending facilitation system. Current CCL2/CCR2-targeted therapeutic strategies and their development status are discussed, highlighting novel avenues for chronic pain management.

BACKGROUND: Over 20 million colonoscopies are performed in China annually. An automatic clinical decision support system (CDSS) with accurate semantic recognition of colonoscopy reports and guideline-based is helpful to relieve the increasing medical burden and standardize the healthcare. In this study, the CDSS was built under a hierarchical-label interpretable classification framework, trained by a state-of-the-art transformer-based model, and validated in a multi-center style. METHODS: We conducted stratified sampling on a previously established dataset containing 302,965 electronic colonoscopy reports with pathology, identified 2041 patients' records representative of overall features, and randomly divided into the training and testing sets (7:3). A total of five main labels and 22 sublabels were applied to annotate each record on a network platform, and the data were trained respectively by three pre-training models on Chinese corpus website, including bidirectional encoder representations from transformers (BERT)-base-Chinese (BC), the BERT-wwm-ext-Chinese (BWEC), and ernie-3.0-base-zh (E3BZ). The performance of trained models was subsequently compared with a randomly initialized model, and the preferred model was selected. Model fine-tuning was applied to further enhance the capacity. The system was validated in five other hospitals with 3177 consecutive colonoscopy cases. RESULTS: The E3BZ pre-trained model exhibited the best performance, with a 90.18% accuracy and a 69.14% Macro-F1 score overall. The model achieved 100% accuracy in identifying cancer cases and 99.16% for normal cases. In external validation, the model exhibited favorable consistency and good performance among five hospitals. CONCLUSIONS The novel CDSS possesses high-level semantic recognition of colonoscopy reports, provides appropriate recommendations, and holds the potential to be a powerful tool for physicians and patients. The hierarchical multi-label strategy and pre-training method should be amendable to manage more medical text in the future.

OBJECTIVES: To investigate the incidence of myocardial injury in children with rotavirus-induced diarrhea, analyze its risk factors, and develop a predictive model for myocardial injury. METHODS: A retrospective analysis was conducted on 203 children diagnosed with rotavirus infection at the Suzhou Wujiang District Children's Hospital from January 2021 to December 2023. The children were divided into groups based on the presence or absence of myocardial injury. Basic information and laboratory indicators at admission were collected and compared between the two groups. LASSO regression was used to screen potential risk factors, followed by multivariate logistic regression to evaluate independent factors. A nomogram model was established and validated. RESULTS: Out of 203 children with rotavirus infection, 53 cases (26.1%) showed myocardial injury. Age, severe dehydration, metabolic acidosis, red cell distribution width, and blood sodium were closely associated with myocardial injury in children with rotavirus-induced diarrhea (P<0.05). The area under the receiver operating characteristic curve for the predictive model of myocardial injury was 0.841 (95%CI: 0.777-0.905), with a sensitivity of 73.6% and specificity of 85.3%. The model curve closely fit the ideal diagonal line. Decision curve analysis showed that using the model for prediction resulted in the highest net benefit when the probability threshold was 0.18-0.98. CONCLUSIONS The model developed in this study can predict the risk of myocardial injury in children with rotavirus-induced diarrhea.

Objective:To investigate the differences in clinical outcomes of septic children with varying serum zinc levels,and to analyze the relationship between reduced serum zinc levels and organ dysfunction as well as 28-day mortality in septic children.Methods:This study conducted a retrospective analysis of clinical data from pediatric patients diagnosed with sepsis or septic shock in the Department of critical care medicine of the children's Hospital of Soochow University between January 2017 and December 2022.Clinical characteristics,organ dysfunction,and prognosis were compared between two groups:children with low serum zinc levels and those with normal zinc levels.Results:The serum zinc level of septic children within 24 hours of admission was 9.60(5.52,13.80)μmol/L,with 50.54%(94/186)of the children exhibiting low serum zinc levels(<10.07 μmol/L).Compared to the normal serum zinc group,the low serum zinc group had a significantly lower Pediatric Critical Illness Score(PCIS)[(78.71±9.35)vs.(85.12±8.51),P=0.005]and higher 28-day mortality(46.80%vs.14.13%,P<0.001).The low serum zinc group also had a higher proportion of invasive mechanical ventilation(64.89%vs.47.82%,P=0.019),renal replacement therapy(15.59%vs.3.26%,P=0.003),and use of vasoactive drugs(56.38%vs.30.43%,P<0.001).The rate of underlying conditions in the low serum zinc group was significantly higher than that in the normal serum zinc group(57.44%vs.36.95%,P=0.005).Additionally,the low serum zinc group had a higher incidence of disseminated intravascular coagulation(DIC),respiratory failure,acute kidney injury,shock,and multiple organ dysfunction syndrome(MODS)compared to the normal serum zinc group(P<0.05).Serum zinc levels had predictive value for 28-day mortality in septic children(AUC=0.813;95%CI:0.725～0.902;P<0.001).A serum zinc level of less than 6.950 μmol/L predicted the death of septic children with a sensitivity of 0.618 and a specificity of 0.902.Conclusion:Sepsis in children is commonly associated with low serum zinc levels,especially in those with underlying conditions such as hematologic and oncologic disorders.Sepsis patients hypozincemia with a higher incidence of DIC,respiratory failure,acute kidney injury,shock,and MODS.A serum zinc level below 6.95 μmol/L serves as a significant predictor of 28-day mortality in children with severe sepsis.

This research aims to construct a stable epithelial cell senescence model for screening and e-valuation of senolytics.We explored the optimal conditions for doxorubicin-induced senescence of non-transformed epithelial cells MCF 10A,including the optimal induction concentration,the optimal inter-vention time,and the optimal senescence duration,and confirmed the feasibility of MCF 10A as an epi-thelial senescence model by multiple ways.The optimal condition for Doxorubicin-induced senescence of MCF 10A cells was treatment with 0.6 μmol/L Doxorubicin for 16 h to achieve the best senescence state on the 8th day.Under the optimal induction conditions,the positive rate of senescence-associated β-gal-actosidase(SA-β-gal)staining in the treated group reached 97％.At the same time,biochemical results of detecting the expression of mRNA,proteins,and immunofluorescence demonstrated that the expression levels of senescence-associated secretory phenotype(SASP),p16,p21 and p53 in the treated group were significantly higher than those in the control cells,and Lamin B1 was significantly decreased(P＜0.001),which were consistent with the specific characteristics of senescence.In summary,an epithelial senescence model was successfully induced in MCF 10A cells by Doxorubicin in this study,which will promote the screening of senolytics for senescent epithelial cells.

Objective:To study the spatial distribution and characteristics of iodine content in residential drinking water in Shaanxi Province, and provide a basis for scientific prevention and control of iodine deficiency disorders.Methods:From March to October 2022, an investigation was conducted in all counties (districts, referred to as counties) of Shaanxi Province, with administrative villages as survey units. For centralized water supply systems, two terminal water samples were collected, and iodine content was measured separately, with the average value representing the drinking water iodine content at that location. For decentralized water supply systems, a 10% sampling method was used to divide each administrative village into five areas (east, south, west, north, and center), with 10% of water wells sampled from each area (if fewer than 10 water wells, the well with the largest drinking population was selected; if fewer than 5 wells, all wells were sampled). One water sample was collected from each water well, and iodine content was determined using the arsenic-cerium catalytic spectrophotometry method. Spatial autocorrelation and spatial scan analysis were used to analyze the spatial distribution and characteristics of drinking water iodine content.Results:A total of 53 990 drinking water samples were collected, with a median water iodine content of 6.66 μg/L, ranging from 0.10 to 779.40 μg/L. Drinking water iodine content was detected in 112 counties, showing a significant spatial positive correlation (global autocorrelation, Moran's I = 0.74, Z = 43.83, P < 0.001). Local autocorrelation analysis showed that the difference in the distribution of iodine content in drinking water among 36 counties was statistically significant ( P < 0.05), with 22 counties showing low-low clustering and 12 counties showing high-high clustering. Spatial scanning identified three water iodine clustering areas, including two high-water iodine cluster areas and one low-water iodine cluster area. Conclusions:The distribution of iodine content in residential drinking water in Shaanxi Province shows significant spatial clustering and heterogeneity, requiring targeted interventions to achieve precise prevention and control of iodine deficiency disorders.

Objective To investigate the potential association between XRCC1 and XRCC3 gene polymor-phisms and susceptibility to cervical cancer within populations infected with high-risk human papillomavirus(HPV).Methods A cohort of 176 cervical cancer patients with high-risk HPV infection,diagnosed at the First People's Hospital of Kashgar Region between January 2021 and January 2023,were enrolled as the study group.Concurrently,177 women infected with high-risk HPV but without cervical cancer were enrolled as the control group.All participants were followed up,and genotyping along with HPV subtyping was conducted for subsequent analysis.Results The XRCC1 Arg399Gln genotype showed a significant association with cervical cancer risk among individuals infected with specific HPV subtypes(e.g.,HPV-16,-18,-52,and-58),but no significant correlation was observed with the number of concurrent HPV infections.Compared to non-carriers,individuals carrying the XRCC1 Arg399Gln genotype exhibited an increased risk of cervical cancer,particularly among those infected with HPV-16,-18,-52,or-58.Statistically significant differences were found between the control group and the cervical cancer group for the XRCC1 Arg280His(P<0.001)and XRCC3 Thr241Met(P<0.05)genotypes;however,no significant differences were observed for XRCC1 Arg194Trp and XRCC1 Arg399Gln polymorphisms(P>0.05).Further analysis revealed that the XRCC1 Arg280His polymorphism was associated with a 3.57-fold higher risk of cervical cancer(OR=3.57,95%CI:1.99～6.43),while XRCC1 Arg194Trp showed no significant association(P>0.05).Additionally,XRCC1 Arg399Gln was associated with a reduced risk(OR=0.57,95%CI:0.34～0.96),and XRCC3 Thr241Met was linked to a decreased risk of cervical cancer(OR=0.22,95%CI:0.06～0.84).Conclusions In the HPV-infected population of Kashgar,the XRCC1 Arg280His polymorphism is significantly associated with an increased risk of cervical cancer(OR=3.57),whereas the XRCC3 Thr241Met(GG)genotype exhibits a protective effect(OR=0.16).The XRCC1 Arg399Gln variant demonstrates a protective association specifically among TT homozygotes(OR=0.57).In contrast,the XRCC1 Arg194Trp polymorphism does not show a statistically significant association with cervical cancer risk.

Objective To investigate iodine content in drinking water and clarify the distribution characteristics of iodine in water in Shaanxi Province.Methods A cross-sectional survey method was used to collect water samples from administrative villages in the province.Two tap water samples were taken from the centralized water supply villages,and 10％samples were taken from the decentralized water supply villages.Water iodine was detected by arsenic cerium catalytic spectrophotometry.Water iodine areas were divided according to national standards:＜40 μg/L was iodine deficiency area,40-100 μg/L was iodine adequate area,＞100 μg/L was high iodine area.According to the ecological regionification scheme of the Chinese Academy of Sciences,Shaanxi Province was divided into three types:the central and eastern Inner Mongolia Platea-Loess Plateau ecological region,the Fenwei Basin ecological region,and the Qinba Mountains ecological region.SPSS 25.0 was used for statistical analysis.Results The median of water iodine in Shaanxi Province was 6.66 μg/L.The survey of water iodine content was conducted in 22 848 administrative villages,1 309 townships,112 counties and 14 municipalities in the whole province.The median water iodine was less than 40 μg/L in 91.75％(20 963/22 848)of the administrative villages,between 40 and 100 μg/L in 7.40％(1 691/22 848)of the administrative villages,and more than 100 μg/L in 0.85％(194/22 848)of the administrative villages.The median of water iodine in the central and eastern Inner Mongolia Platea-Lose Plateau ecological zone,the Fenwei Basin ecological zone,and Qinba Mountains ecological zone was 12.35,8.88,and 2.00 μg/L,respectively,and the differences among different ecological zones were statistically significant(H=6 616.23,P＜0.001).The median of water iodine of centralized and decentralized water supply was 6.72 and 6.21 μg/L,respectively,and differences between different water supply methods were statistically significant(Z=5.638,P＜0.01).Conclusion The overall external environment of Shaanxi Province is iodine deficient,and most of the administrative villages are iodine deficient areas.There are a certain proportion of high iodine water source areas and suitable iodine areas.
