Objective To analyze the correlation between serum soluble Klotho protein(sKL)and tendino-C(TN-C)and the severity of disease and oxidative stress in children with immunoglobulin A(IgA)nephropa-thy.Methods A total of 85 children with IgA nephropathy admitted to the hospital from July 2019 to August 2022 were selected as IgA nephropathy group,and 85 healthy patients who underwent physical examination in the hospital during the same period were selected as healthy group.Serum sKL and TN-C levels were com-pared between the two groups.Receiver operating characteristic(ROC)curve was drawn to analyze the value of serum sKL,TN-C and their combination in predicting the occurrence of IgA nephropathy.IgA nephropathy group was divided into mild group(28 cases),moderate group(39 cases)and severe group(18 cases)accord-ing to 24 h urinary protein quantity.Serum sKL,TN-C levels and oxidative stress indexes[malondialdehyde(MDA),superoxide dismutase(SOD)and advanced oxidation protein product(AOPP)]of the three groups were compared.The correlation between serum sKL and TN-C levels and oxidative stress indexes was ana-lyzed by Spearman correlation,and the correlation between serum sKL and TN-C levels and the severity of IgA nephropathy in children was examined by Kendall's Tau-b.Results The serum sKL level in IgA ne-phropathy group was lower than that in healthy group,and the serum TN-C level was higher than that in healthy group,the difference was statistically significant(P＜0.05).ROC curve showed that the area under the curve and 95％CI of serum sKL,TNC and their combination predicted the occurrence of IgA nephropathy were 0.726(95％CI:0.648-0.803),0.853(95％CI:0.796-0.909)and 0.891(95％CI:0.845-0.937).The level of serum sKL in severe group was lower than that in moderate and mild groups,while the level of serum TN-C was higher than that in moderate and mild groups,and the difference was statistically significant(P＜0.05).The serum SOD level of severe group was lower than that of moderate group and mild group,and the serum AOPP and MDA levels were higher than those of moderate group and mild group,the difference was statistically significant(P＜0.05).Spearman correlation showed that sKL level was positively correlated with SOD(r＞0,P＜0.05),and negatively correlated with AOPP and MDA(r＜0,P＜0.05).TN-C level was negatively correlated with SOD(r＜0,P＜0.05),and positively correlated with AOPP and MDA(r＞0,P＜0.05).Conclusion The levels of serum sKL and TN-C in children with IgA nephropathy are related to the severity of disease and oxidative stress,and the combination of SKL and TN-C can effectively predict the occurrence of IgA nephropathy.

Fermentum Rubrum（FR） is a kind of traditional Chinese medicine with dual-use functions of medicine and food， which has been used for more than 1 000 years. By referring to the ancient herbal classics and modern laws and regulations， the author sorted out the origin of FR， sorted out the development of processing， and analyzed the problems existing in the quality standard， aiming to provide a basis for further research and development of FR. There are many theories about the origin of FR. After summarizing and sorting out the relevant literature， three viewpoints are mainly drawn， including Han dynasty origin theory， Wei and Jin origin theory and Tang dynasty origin theory. After synthesizing the views of various schools， it is believed that the origin of FR should be no later than the Eastern Han dynasty. FR is made from rice by fermentation， which has the effect of strengthening the spleen， eliminating food， promoting blood circulation and removing stasis after fermentation. Although the natural fermentation in ancient times has been able to pay attention to the influence of temperature， humidity and strain on the quality of FR， due to the low level of science and technology， there are still problems such as complicated and cumbersome process， large workload and high labor cost. To the pure fermentation in modern times， the fermentation processing method of FR has been evolved， gradually improved and perfected. However， due to the lack of standardized research， there is no unified standard for the fermentation process of FR in various regions， and the quality standard lags behind seriously， which leads to the unstable product quality on the market. Among the 15 specifications for the preparation of FR， only 6 have been published in the past 5 years， and most of them have not been revised in a timely manner， and some of them have not been included in the updated version. Based on this， it is recommended to carry out a systematic study on processing technology of FR， and the best process is selected to accelerate the revision and improvement of its standardization， so as to improve the quality of FR sold in the market and promote its stable and sustainable development.

Background::Liver cancer is largely resistant to chemotherapy. This study aimed to identify the effective chemotherapeutics for β-catenin-activated liver cancer which is caused by gain-of-function mutation of catenin beta 1 ( CTNNB1), the most frequently altered proto-oncogene in hepatic neoplasms. Methods::Constitutive β-catenin-activated mouse embryonic fibroblasts (MEFs) were established by deleting exon 3 ( β-cateninΔ(ex3)/+ ), the most common mutation site in CTNNB1 gene. A screening of 12 widely used chemotherapy drugs was conducted for the ones that selectively inhibited β-cateninΔ(ex3)/+ but not for wild-type MEFs. Untargeted metabolomics was carried out to examine the alterations of metabolites in nucleotide synthesis. The efficacy and selectivity of methotrexate (MTX) on β-catenin-activated human liver cancer cells were determined in vitro. Immuno-deficient nude mice subcutaneously inoculated with β-catenin wild-type or mutant liver cancer cells and hepatitis B virus ( HBV); β-cateninlox(ex3)/+ mice were used, respectively, to evaluate the efficacy of MTX in the treatment of β-catenin mutant liver cancer. Results::MTX was identified and validated as a preferential agent against the proliferation and tumor formation of β-catenin-activated cells. Boosted nucleotide synthesis was the major metabolic aberration in β-catenin-active cells, and this alteration was also the target of MTX. Moreover, MTX abrogated hepatocarcinogenesis of HBV; β-cateninlox(ex3)/+ mice, which stimulated concurrent Ctnnb1-activated mutation and HBV infection in liver cancer. Conclusion::MTX is a promising chemotherapeutic agent for β-catenin hyperactive liver cancer. Since repurposing MTX has the advantages of lower risk, shorter timelines, and less investment in drug discovery and development, a clinical trial is warranted to test its efficacy in the treatment of β-catenin mutant liver cancer.

Objective To explore the value of blood inflammatory load in predicting overall survival of elderly patients with epithelial ovarian cancer(EOC).Methods Elderly patients with EOC were selected,and their clinical data and peripheral blood parameters were collected.We constructed an inflammation-related blood scoring system using univariate and multivariate Cox regression analysis.The Kaplan-Meier method was used for survival analysis.We used Cox proportional hazards analysis to identify the independent prognostic factors.A nomogram model was constructed based on independent prognostic factors,and the receiver operating characteristic curve,C-index,and calibration curve were used to evaluate the model.Results Patients with high blood inflammatory load had worse prognosis(P=0.002).Compared with the low inflammatory load group,patients with high inflammatory load had later clinical stages and larger ascites volume(P<0.05).Cox regression analysis showed that ACCI,CA125,residual lesions,and blood score were independent factors affecting overall survival(P<0.05).Conclusion The blood inflammatory load is the biomarker for the prognosis of elderly patients with EOC.Scoring the inflammatory load in the blood can assist in efficacy monitoring and treatment intervention of ovarian cancer patients.

Objective By population survey,to explore the epidemiological characteristics of gastric precancerous lesions in Lishui District of Nanjing and provide objective basis for the prevention and treatment of early gastric cancer.Methods From July 2021 to December 2022,21 977 patients who received endoscopy and/or 13C-UBT in Lishui District People's Hospital and 6 medical community units in Nanjing City were retrospectively analyzed for demography characteristics,detection rate of gastric precancerous lesions,and H.Pylori infection rate.Results(1)590 cases of gastric precancerous lesions were detected(detection rate 2.68%);(2)The total detection rate of precancerous lesions and three pathological types in males were all higher than those in females(all P<0.001);(3)The minimum age for the total detection rate of precancerous lesions in males and the mini-mum age for each pathological type were lower than in females(P<0.001,0.009,0.005,0.002);(4)The popu-lation total H.pylori infection rate was 23.10%,the H.pylori infection rate in patients with precancerous lesions was higher than that in non-precancerous lesions(P<0.001),both H.pylori infection rate of male and female in precancerous lesions were all higher than those of non-precancerous lesions of the same sex(all P<0.001),in addition,the H.pylori infection rate of male whether in precancerous or non-precancerous lesions was higher than that of female(all P<0.001);(5)The precancerous lesions detection rate in male,female,and the overall age range of 20～29 to 70～79 years is positively correlated with age growth(P<0.001),and rapidly decreases after the age of 79,the of H.pylori infection rate was also positively correlated with age growth(P<0.001),and the trend of age change(P<0.001)was parallel to the precancerous lesions detection rate.Conclusions The detec-tion rate of gastric precancerous lesions in this region is above the average level in China;the total H.pylori infec-tion rate is at a relatively low level in China;the H.pylori infection rate is parallel to the age trend of the detection rate of gastric precancerous lesions,and increases with age.

Objective To detect the expression of acrosin binding protein(ACRBP)in serum and tumor tissue of patients with epithelial ovarian cancer(EOC),and to investigate the relationship between the expres-sion of acrosin binding protein(ACRBP)in serum and tumor tissue of patients with epithelial ovarian cancer(EOC)and first-line chemotherapy effect and prognosis.Methods The expression and prognostic effects of ACRBP mRNA in OC were analyzed using data obtained from Gene Expression Profiling Interactive Analysis Database.Then,tissue specimens and serum samples were collected from 95 patients with EOC who under-went surgery at the hospital between October 2019 and December 2021.In addition,30 samples of ovarian be-nign tumor tissue were selected as the benign tumor control group and 30 serum samples from healthy volun-teers were selected as the normal control group.The expression of ACRBP was detected by immunohisto-chemical staining.After first-line chemotherapy was completed,solid tumor efficacy evaluation criteria version 1.1 was used to evaluate chemotherapy effects,and the patients were divided into sensitive group and drug-re-sistant group.The sensitive group included complete response(CR)and partial response(PR)patients,and the drug-resistant group included stable disease(SD)and progressive disease(PD)patients.Results In the public database,ACRBP mRNA expression was significantly increased in OC patients(P＜0.05),and its high expression was associated with poor overall survival(OS).In clinical samples,ACRBP was mainly expressed in the cytoplasm of EOC tumor cells,while no ACRBP was detected in the ovarian tissues of benign tumor control group.The expression of ACRBP in first-line chemotherapy resistant group was significantly higher than that in sensitive group,and the difference was statistically significant(P＜0.001).The area under receiv-er operating characteristic(ROC)curve of ACRBP expression for predicting first-line chemotherapy resistance was 0.830(95％CI:0.743-0.916),the cut off value was 8.65 points,and the sensitivity and the specificity were 80.0％and 77.1％,respectively.High expression of ACRBP was an independent risk factor for the prog-nosis of OS and PFS in patients with EOC(P＜0.05).According to the median expression of ACRBP,pa-tients with EOC were divided into low ACRBP expression group(＜8.27 points)and high ACRBP expression group(≥8.27 points).The OS and progression-free survival(PFS)of patients with high expression of ACRBP were significantly shorter(P＜0.05).Conclusion High expression of ACRBP in EOC patients is closely related to first-line chemotherapy resistance and poor prognosis.ACRBP has the potential to be a new biomarker for the prediction of first-line chemotherapy effect and prognosis.

Objective:To investigate the clinical outcome of endovascular treatment vs. drug treatment in patients with symptomatic non-acute long-segment occlusion of the internal carotid artery. Methods:Based on prospective cohort registration research data, patients with symptomatic non-acute long-segment occlusion of internal carotid artery were retrospectively included. They were divided into a drug treatment group and an endovascular treatment group according to the actual treatment received. The latter was further divided into a successful recanalization group and an unsuccessful recanalization group. The endpoint events included ipsilateral ischemic stroke, any stroke, and all-cause death. Multivariate logistic regression analysis was used to compare the endpoint events between groups during the perioprocedural period (within 30 days), and multivariate Cox proportional hazards model was use to compare the endpoint events between the groups during the long-term follow-up. Results:A total of 684 patients were included, of which 570 (83.33%) were male, median aged 63 years (interquartile range, 56-70 years). Three hundred and fifty-three patients (51.6%) received drug treatment; 331 (48.4%) received endovascular treatment, of which 161 (48.6%) had successful recanalization. The median follow-up time was 1 223 days (interquartile range, 646.5-2 082 days), with 109 patients (15.9%) experiencing stroke recurrence events (including 87 ipsilateral ischemic stroke) and 78 (11.4%) experiencing all-cause mortality. The risk of any stroke during the perioprocedural period in the successful recanalization group was significantly higher than that in the drug treatment group (odds ratio 3.679, 95% confidence interval 1.038-13.036; P=0.044), but the risk of ipsilateral ischemic stroke recurrence (risk ratio 0.347, 95% confidence interval 0.152-0.791; P=0.012) and all-cause mortality (risk ratio 0.239, 95% confidence interval 0.093-0.618; P=0.003) during the long-term follow-up were significantly lower than those in the drug treatment group. Conclusions:In patients with symptomatic non-acute long-segment occlusion of the internal carotid artery, endovascular treatment can increase the risk of stroke recurrence within 30 days, but successful recanalization can reduce the risks of long-term ipsilateral ischemic stroke recurrence and all-cause mortality.

Despite significant achievements of deep learning in medical image segmentation,there are challenges for brain tumor segmentation using deep learning,such as insufficient receptive field,excessive redundant information,and information loss.To address these issues,a novel brain tumor segmentation network model(EAU-Net)is proposed based on encoder-decoder structure.EAU-Net incorporates an effective receptive field expansion block and an attention fusion module to minimize the adverse effects caused by insufficient receptive field and excessive redundant information which often occurred in the current brain tumor segmentation network.Additionally,a bottleneck resampling module based on inverted residual structure is introduced to effectively avoid information loss during upsampling and downsampling,while deep convolutions are used to reduce computational complexity.Experimental results on the BraTS2020 dataset reveal that EAU-Net achieves the highest segmentation accuracy,demonstrating its feasibility and effectiveness for brain tumor segmentation.

Objective:To analyze the efficacy of endoscopic surgical repair in the treatment of type Ⅲ laryngeal clefts and to explore the feasibility of the treatment for type Ⅲ laryngeal clefts. Methods:The clinical data of 6 children with type Ⅲ laryngeal clefts who underwent endoscopic surgical repair in our department from June 2018 to January 2023 were analyzed retrospectively. The operation was performed under combined intravenous and general anesthesia,preserving the spontaneous breathing of the children. With the assistance of 4 mm/0° endoscope, radiofrequency knife or laryngeal scissors were used to make fresh wounds along the edge of laryngeal clefts,and cotton pads infiltrated with adrenaline （1:10 000） were used to compress the wound. 6-0 PDP suture was used to suture 3-6 stitches according to the extent of laryngeal clefts. Modified barium swallowing test （MBS） was performed 3 months after operation. Results:All the children were successfully treated with endoscopic surgical repair. After surgery, 2 cases were transferred to pediatric intensive care unit （ICU） for 7 days of monitoring, and the rest were transferred back to the general ward. There were no postoperative complications. The symptoms of dysphagia, laryngitis and recurrent pneumonia were improved in all children. According to the follow-up results of postoperative MBS,no aspiration was found in all children, and 2 children had intermittent cough when drinking large amounts of water. During the follow-up, there were 2 cases of recurrence, and the cracks were completely repaired after the second endoscopic surgical repair treatment,and no recurrence has been observed so far. Conclusion:Endoscopic surgical repair can be applied to some children with type Ⅲ laryngeal clefts with less intraoperative bleeding and fewer operative complications. It can significantly improve the symptoms such as swallowing dysfunction and recurrent pneumonia. It is a safe and effective surgical treatment.
