Objective:To evaluate the clinical application of urine sediment score (USS) in early diagnosis, etiological differentiation, staging and prognosis of acute kidney injury (AKI), and to investigate the diagnostic efficacy of independent USS and its combination with blood urea nitrogen(Bun) serum creatinine(sCr) and uric acid(UA) in AKI.Methods:From August 23 to September 28, 2023, 9 020 morning urine samples of hospitalized patients in the First Hospital of Jilin University were detected by Sysmex UF5000.A total of 3 226 ssamples with small and round cell (SRC) > 1/μl and/or CAST>1/μl were screened for microscopic examination, and 404 cases with positive renal tubular epithelial cells and/or cast were enrolled in this study. There were 218 males and 186 females, aged 59.5 (49.0, 71.0) years. The 404 cases were divided into the USS AKI group (345 cases) and the USS non-AKI group (59 cases) according to the USS results based on the microscopic findings. According to Kidney Disease: Improving Global Outcomes (KDIGO) criteria, they were divided into KDIGO criteria AKI group (63 cases) and KDIGO criteria non-AKI group (341 cases), and the AKI group was divided into renal AKI group (33 cases) and non-renal AKI group (30 cases). According to the clinical diagnosis recorded in the medical records, they were divided into clinically diagnosed AKI group (29 cases) and clinically diagnosed non-AKI group (375 cases).The χ 2 test or Fisher exact test was used to compare USS in different AKI causes and stages. Logistic regression was used to calculate the odds ratio of renal AKI and stage 3 AKI. The area under the receiver operating characteristic curve was used to evaluate the sensitivity and specificity of USS, sCr, UA and Bun alone and in combination in the diagnosis of AKI, and the best cut-off value, sensitivity and specificity in the diagnosis of AKI were calculated. P < 0.05 was considered statistically significant. Results:The USS was used to identify the etiology of KDIGO standard AKI group,and there were significant differences in USS between renal AKI group and non-renal AKI group (χ 2=11.070, P<0.001). Compared to USS=1, the odds ratio of renal AKI was 8.125 when USS≥2 (95% CI 2.208—29.901). There was a statistically significant difference in the comparison of USS between groups in each stage of the AKI staging study based on USS (χ 2=15.724, P<0.05). Compared to USS=1, the odds ratio of stage 3 AKI was 9.714 when USS≥2 (95% CI 1.145-82.390). The AUC of independent USS in the diagnosis of AKI was 0.687 (95% CI 0.618-0.757, P<0.001), the specificity was 65.7% and the sensitivity was 61.9%. The AUC of USS combined with Bun, sCr, UA in the diagnosis of AKI was 0.794 (95% CI 0.608-0.980, P<0.05), the specificity was 82.4%, and the sensitivity was 88.9%. Conclusions:There wasan increased likelihood of renal AKI or stage 3 AKI while USS≥2,and whose combination with Bun, sCr and UA will improve the diagnostic efficiency of AKI.

ObjectiveThis paper aims to analyze the current status of outcome indicators in randomized controlled trials （RCT） of traditional Chinese medicine （TCM） for treating chronic atrophic gastritis （CAG）， so as to provide references for constructing the core outcome set （COS） of TCM in the treatment of CAG. MethodChina National Knowledge Infrastructure （CNKI）， Wanfang， VIP， SinoMed， PubMed， Embase， and Cochrane Library databases were searched for RCTs of TCM in the treatment of CAG in the last five years. The risk of bias of included studies was evaluated， and the selection status of outcome indicators was statistically analyzed. ResultA total of 150 RCTs were included， with a sample size of 44-398 cases. 164 outcome indicators were reported， with an application frequency of 1 229 times. The outcome indicators were classified into seven indicator domains according to functional attributes， followed by physical and chemical examination （69.41%）， TCM syndrome （12.69%）， symptoms and signs （11.15%）， safety indicators （5.37%）， quality of life （0.65%）， long-term prognosis （0.65%）， and economic evaluation （0.08%）. According to the statistical analysis， there were problems in the selection of outcome indicators in RCTs of TCM for treating CAG， including various indicators， non-standard name reports， unclear primary and secondary indicators， random combination of subjective and objective indicators， neglected patient report outcome indicators， missing long-term prognosis and economic indicators， insufficient reporting of safety indicators， and inconsistent measurement tools and measurement time points. ConclusionIn the past five years， there have been many problems in the selection of outcome indicators in RCTs of TCM for treating CAG. It is necessary to actively promote the construction of the COS of TCM in the treatment of CAG and promote the high-quality development of clinical research of TCM.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

Objective:To re-evaluate the reliability of the conclusions of the systematic reviews (SR)/meta-analysis (MA) of Traditional Chinese Medicine (TCM) in the treatment of functional dyspepsia (FD).Methods:CNKI, CBM, WanFang Data, VIP, PubMed, Cochrane Library, and Embase were searched from the establishment of the database to March 30, 2022. Two researchers independently screened literature and extracted data, and included SRs/MAs in the treatment of FD with TCM. The AMSTAR 2 and GRADE tools were used to evaluate the included the study carried out methodological quality evaluation, outcome evidence quality grading, and descriptive analysis of the main outcome.Results:A total of 28 SRs/MAs were included, with 34 outcome indicators. According to the AMSTAR 2 evaluation results, 21 SRs/MAs were of medium quality, and 7 SRs/MAs were of low quality. The GRADE quality of evidence grading results showed that of the 100 evidence bodies, 13 were of high quality, 58 were of moderate quality, 24 were of low quality, and 5 were of very low quality.Conclusion:TCM in the treatment of FD can improve the clinical efficiency, improve the cure rate, reduce the recurrence rate, and improve the clinical symptoms, but the methodological quality and evidence quality of related SRs/MAs have certain defects, so this conclusion should be treated with caution.

Objective:To explore the structural and functional alterations of related brain regions in patients after cardiopulmonary resuscitation (CPR) by brain magnetic resonance imaging (MRI).Methods:A single-center, observational, cross-sectional study design was used. Patients who had brain MRI scans during hospitalization between July 2020 and July 2021 in Emergency Department of the First Affiliated Hospital of Nanjing Medical University and had good neurologic outcomes were consecutive enrolled in this study. The healthy control (HC) group consisted of age- and sex-matched volunteers. The demographic and clinical data were recorded. The modified Rankin Scale (mRS) was used to check the recovery and degree of continued disabilities when patients performed MRI. Montreal cognitive assessment (MoCA) was used to assess cognitive functions. The analyses of voxel-based morphometry (VBM) and fractional amplitude of low-frequency fluctuation (fALFF) were conducted. After data preprocessing, comparison of gray matter volume (GMV) and fALFF values between the case group and HC group were carried out, and the information of different brain regions was obtained. Partial correlation analyses were performed to evaluate the correlation between the image parameters of different clusters and clinical parameters.Results:Totally 13 patients were enrolled in this study and 13 were in the HC group. All patients achieved good neurologic outcome; mRS was 3 in 1 case, 2 in 3 cases, and 1 in 5 cases during MEI examination. The case group showed significantly lower MoCA score compared with the HC group ( P<0.001). There were significantly decreased GMVs in the right inferior frontal gyrus, superior temporal gyrus, left superior temporal gyrus, and transverse temporal gyrus in the case group. The patients showed significantly decreased fALFF values in the left postcentral gyrus and precentral gyrus, while increased fALFF values in the right putamen than the HC group (voxel-level P<0.001 and cluster-level P<0.05 with GRF correction). In addition, mean fALFF value in the right putamen was negatively correlated with MoCA score in the case group ( r=-0.710, P=0.021). Conclusions:Patients after CPR may have GMVs and neuronal spontaneous activity changes in some brain regions, and VBM and fALFF methods can be used to objectively evaluate the impaired brain functional activity in patients after successful CPR.

Objective:To study the distribution and antibiotics resistance of the main pathogens of neonatal purulent meningitis in different regions of China.Methods:A retrospective descriptive clinical epidemiological study was conducted in children with neonatal purulent meningitis which admitted to 18 tertiary hospitals in different regions of China between January 2015 to December 2019. The test results of blood and cerebrospinal fluid, and drug sensitivity test results of the main pathogens were collected. The distributions of pathogenic bacteria in children with neonatal purulent meningitis in preterm and term infants, early and late onset infants, in Zhejiang Province and other regions outside Zhejiang Province, and in Wenzhou region and other regions of Zhejiang Province were analyzed. The chi-square test was used for statistical analysis.Results:A total of 210 neonatal purulent meningitis cases were collected. The common pathogens were Escherichia coli ( E. coli)(41.4%(87/210)) and Streptococcus agalactiae ( S. agalactiae)(27.1%(57/210)). The proportion of Gram-negative bacteria in preterm infants (77.6%(45/58)) with neonatal purulent meningitis was higher than that in term infants (47.4%(72/152)), and the difference was statistically significant ( χ2=15.54, P=0.001). There were no significant differences in the constituent ratios of E. coli (36.5%(31/85) vs 44.8%(56/125)) and S. agalactiae (24.7%(21/85) vs 28.8%(36/125)) between early onset and late onset cases (both P>0.05). The most common pathogen was E. coli in different regions, with 46.7%(64/137) in Zhejiang Province and 31.5%(23/73) in other regions outside Zhejiang Province. In Zhejiang Province, S. agalactiae was detected in 49 out of 137 cases (35.8%), which was significantly higher than other regions outside Zhejiang Province (11.0%(8/73)). The proportions of Klebsiella pneumoniae, and coagulase-negative Staphylococcus in other regions outside Zhejiang Province (17.8%(13/73) and 16.4%(12/73)) were both higher than those in Zhejiang Province (2.9%(4/137) and 5.1%(7/137)). The differences were all statistically significant ( χ2=14.82, 12.26 and 7.43, respectively, all P<0.05). The proportion of Gram-positive bacteria in Wenzhou City (60.8%(31/51)) was higher than that in other regions in Zhejiang Province (38.4%(33/86)), and the difference was statistically significant ( χ2=6.46, P=0.011). E. coli was sensitive to meropenem (0/45), and 74.4%(32/43) of them were resistant to ampicillin. E. coli had different degrees of resistance to other common cephalosporins, among which, cefotaxime had the highest resistance rate of 41.8%(23/55), followed by ceftriaxone (32.4%(23/71)). S. agalactiae was sensitive to penicillin, vancomycin and linezolid. Conclusions:The composition ratios of pathogenic bacteria of neonatal purulent meningitis are different in different regions of China. The most common pathogen is E. coli, which is sensitive to meropenem, while it has different degrees of resistance to other common cephalosporins, especially to cefotaxime.

ObjectiveTo compare the differences in thyroid hormone levels between adolescents with and without suicidal ideation， and to explore the association between thyroid hormone/suicidal ideation and the antidepressant treatment. MethodsA total of 100 patients were divided into non-suicidal ideation group and suicidal ideation group according to the SIOSS. The levels of thyroid-stimulating hormone （TSH）， triiodothyronine （T3）， thyroxine （T4）， free triiodothyronine （FT3） and free thyroxine （FT4） were compared between the two groups as well as their changes after 6 weeks of antidepressant treatment. ResultsThe levels of FT3， FT4 and T4 in the non-suicidal ideation group were higher than those in the suicidal ideation group. After 6 weeks of antidepressant treatment， the levels of FT3， FT4 and T4 in the suicide ideation group were higher than those before the treatment. The FT3 level in the male non-suicidal ideation group was higher than that in the suicidal ideation group. The levels of FT4 and T4 in the female non-suicidal ideation group were higher than those in the suicidal ideation group （all P<0.05） ConclusionThere are differences in thyroid hormone levels between adolescents with and without suicidal ideation （both with first-episode depression）， and patients with suicidal ideation have significant changes after treatment with antidepressants.

ObjectiveTo investigate the effect of Gegen Qinliantang （GGQLT）-medicated serum on free fatty acid （FFA）-induced nonalcoholic steatohepatitis （NASH） in vitro model of human hepatoma cells HepG2. MethodNASH model of HepG2 cells was established in vitro， and the cells were intervened with different volume fractions of GGQLT-medicated serum and resveratrol. Intracellular lipid deposition in each group was detected by oil red O staining， the level of reactive oxygen species （ROS） in each group were detected by flow cytometry， the levels of glutathione peroxidase （GSH-Px）， superoxide dismutase （SOD）， triglyceride （TG） and malondialdehyde （MDA） in each group were detected by kits. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to measure the mRNA expression levels of nuclear transcription factor （NF）E₂-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， quinone oxidoreductase 1 （NQO1）， Kelch-like epichlorohydrin-associated protein-1 （Keap1）， NF-κB， thioredoxin interacting protein （TXNIP）， interleukin-1β （IL-1β） in HepG2 cells of each group. The protein expression of Nrf2， TXNIP in cells of each group was detected by Western blot. ResultFFA induced large accumulation of intracellular lipids. Compared with the normal group， the activities of GSH-Px and SOD were significantly decreased （P<0.01） and the contents of TG， ROS and MDA were significantly increased （P<0.05， P<0.01） in the model group. Compared with the model group， all GGQLT groups and resveratrol group could elevate intracellular SOD activity to different degrees （P<0.05， P<0.01） and significantly reduce the levels of intracellular ROS and MDA （P<0.05， P<0.01）， GGQLD high- and medium-dose groups and resveratrol group significantly elevated GSH-Px activity （P<0.01）， GGQLD medium- and low-dose groups and resveratrol group significantly decreased TG content （P<0.05， P<0.01）. Compared with the model group， GGQLT high- and medium-dose groups and resveratrol group could significantly upregulate the mRNA expression levels of Nrf2， HO-1 and NQO1 （P<0.01）， all GGQLT groups and resveratrol group could significantly downregulate the TXNIP protein expression level， as well as significantly downregulate the mRNA expression levels of Keap1， NF-κB （P<0.05， P<0.01）. Nrf2-siRNA transfection of cells revealed that Nrf2 expression was significantly downregulated （P<0.01） in the Nrf2-siRNA group of cells by comparing with NC-siRNA group at the corresponding dose of drugs， and the inhibitory effects of GGQLT and resveratrol on TXNIP， IL-1β were attenuated. ConclusionFFA induces the production of ROS and inflammatory factors in HepG2 cells， and GGQLT can improve the anti-inflammatory and antioxidant capacities of cells， and its mechanism may be related to the regulation of Nrf2/TXNIP signaling pathway， so as to improve NASH.

Objective:Investigating the distribution of intestinal Akkermansia muciniphila (AKK) and explore abundance-effect in obesity obesity to provide potential dose effect for obesity intervention.Methods:Clinical data of 6 986 subjects including body mass index, waist circumference, and common confounders such as gender, age, diastolic blood pressure, systolic blood pressure, fasting blood glucose, triglyceride, total cholesterol, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol, and uric acid were collected from Guangdong Gut Microbiome Project in 2008. 16S ribosomal RNA (16S rRNA) sequencing data were used to estimate the genus abundance of AKK as well as its operational taxonomic unites (OTUs). Central obesity and overall obesity were diagnosed according to the criteria of China Obesity Working Group in 2002. Multivariate logistic regression was used to analyze the OR (95% CI) of obesity with one-unite elevation of AKK. The dose effect of AKK on obesity was estimated by comparing the trend of ORs from the 1st to the 20th quantile. Results:A total of three AKK OTUs(AKK OTU1, AKK OTU2, AKK OTU3) were identified: AKK OTU1 and AKK OTU2 were distributed in more than 90% of the population, while AKK OTU3 was distributed at 21.7%; All the OTUs showed a"bimodal"distributional pattern and their correlations with common factors were variable. Disparities of the association with obesity were found between the OTUs and the AKK. AKK OTU1, AKK OTU2, and the genus level of AKK showed significant protective effects against obesity; The ORs (95% CI) were 0.95(0.93-0.98), 0.97(0.94-0.99), 0.93(0.91-0.96), respectively for central obesity; And ORs(95% CI) were 0.88(0.80-0.97), 0.98(0.93-1.02), 0.81(0.74-0.89), respectively for overall obesity. The results were similar after adjustment for common confounders. According to the calculation of dose-effect, the protect effects of AKK increased with accumulated abundance and the minimum effective dose on central obesity and overall obesity was 1.83% and 4.98%, respectively. Conclusion:AKK is a protective factor for obesity, but the dose-effect of AKK and the strain-differences should be considered in the future interventional study.

To study the prognosis-related regulation mechanism of miR-452-5p and its influence on the proliferation and migration of hepatocellular carcinoma (HCC) cells, liver hepatocellular carcinoma (LIHC) dataset in The Cancer Genome Atlas (TCGA) was used to validate the differential expression of miR-452-5p and perform the Kaplan-Meier analysis of overall survival (OS).Target genes of miR-452-5p from TargetscanHuman and miRDB databases were predictived; and differentially expressed genes(DEGs) and weighted gene co-expression network analysis (WCGNA) were completed with GSE14520.Lipofectmine-2000 was used to transfect miR-452-5p mimics, mimics negative control, miR-452-5p inhibitor and inhibitor negative control into Huh7 cells,respectively.The mRNA and protein expression level of RORα in 4 groups were determined by RT-qPCR and Western blot.CCK-8 assay and Transwell assay were conducted to testify the capabilities of proliferation and migration.The regulation between miR-452-5p and RORα was confirmed by the dual luciferase reporter assay.After analysis in the TCGA-LIHC dataset, miR-452-5p had higher expression in HCC tissue than that in normal tissue, which was also associated with a shorter OS.RORα and LAMC1 were discriminated by intersecting of DEGs, WGCNA module genes, and predictive target genes.Survival analysis exhibited that dysregulation of RORα was significantly related to the OS.Overexpression of miR-452-5p in HCC cells suppressed the expression of RORα both in mRNA and protein, and also enhanced the viability and migration of HCC cells.The results of the dual luciferase reporter assay showed that miR-452-5p targeted 3′UTR of RORα.Up-regulated miR-452-5p inhibited the expression of RORα, facilitated the proliferation and migration of HCC cells, and promoted the progression and poor prognosis of HCC.
