Objective:To explore the robust relationship between insomnia and type 2 diabetes mellitus by two-sample Mendelian randomization analysis to overcome confounding factors and reverse causality in observational studies.Methods:We identified strong,independent single nucleotide polymorphisms(SNPs)of insomnia from the most up to date genome wide association studies(GWAS)within European ancestors and applied them as instrumental variable to GWAS of type 2 diabetes mellitus.After excluding SNPs that were significantly associated with smoking,physical activity,alcohol consumption,educational attainment,obesity,or type 2 diabetes mellitus,we assessed the impact of insomnia on type 2 diabetes mellitus using inverse variance weighting(IVW)method.Weighted median and MR-Egger regression analysis were also conducted to test the robustness of the association.We calculated the F statistic of the selected SNPs to test the applicability of instrumental variable and F statistic over than ten indicated that there was little possibility of bias of weak instrumental variables.We further examined the existence of pleiotropy by testing whether the intercept term in MR-Egger regression was significantly different from ze-ro.In addition,the leave-one-out method was used for sensitivity analysis to verify the stability and relia-bility of the results.Results:We selected 248 SNPs independently associated with insomnia at the genome-wide level(P＜5 ×10-8)as a preliminary candidate set of instrumental variables.After clum-ping based on the reference panel from 1000 Genome Project and removing the potential pleiotropic SNPs,a total of 167 SNPs associated with insomnia were included as final instrumental variables.The F statistic of this study was 39.74,which was in line with the relevance assumption of Mendelian randomi-zation.IVW method showed insomnia was associated with higher risk of type 2 diabetes mellitus that po-pulation with insomnia were 1.14 times more likely to develop type 2 diabetes mellitus than those without insomnia(95％CI:1.09-1.21,P＜0.001).The weighted median estimator(WME)method and MR-Egger regression showed similar causal effect of insomnia on type 2 diabetes mellitus.And MR-Egger re-gression also showed that the effect was less likely to be triggered by pleiotropy.Sensitivity analyses pro-duced directionally similar estimates.Conclusion:Insomnia is a risk factor of type 2 diabetes mellitus,which has positively effects on type 2 diabetes mellitus.Our study provides further rationale for indivi-duals at risk for diabetes to keep healthy lifestyle.

Objective:To explore the association between polymorphisms of transforming growth factor-β(TGF-β)signaling pathway and non-syndromic cleft lip with or without cleft palate(NSCL/P)among Asian populations,while considering gene-gene interaction and gene-environment interaction.Methods:A total of 1 038 Asian NSCL/P case-parent trios were ascertained from an international consortium,which conducted a genome-wide association study using a case-parent trio design to investigate the genes affec-ting risk to NSCL/P.After stringent quality control measures,343 single nucleotide polymorphism(SNP)spanning across 10 pivotal genes in the TGF-β signaling pathway were selected from the original genome-wide association study(GWAS)dataset for further analysis.The transmission disequilibrium test(TDT)was used to test for SNP effects.The conditional Logistic regression models were used to test for gene-gene interaction and gene-environment interaction.Environmental factors collected for the study in-cluded smoking during pregnancy,passive smoking during pregnancy,alcohol intake during pregnancy,and vitamin use during pregnancy.Due to the low rates of exposure to smoking during pregnancy and al-cohol consumption during pregnancy(＜3％),only the interaction between maternal smoking during pregnancy and multivitamin supplementation during pregnancy was analyzed.The threshold for statistical significance was rigorously set at P=1.46 × 10-4,applying Bonferroni correction to account for multiple testing.Results:A total of 23 SNPs in 4 genes yielded nominal association with NSCL/P(P＜0.05),but none of these associations was statistically significant after Bonferroni's multiple test correction.How-ever,there were 6 pairs of SNPs rs4939874(SMAD2)and rs1864615(TGFBR2),rs2796813(TGFB2)and rs2132298(TGFBR2),rs4147358(SMAD3)and rs1346907(TGFBR2),rs4939874(SMAD2)and rs1019855(TGFBR2),rs4939874(SMAD2)and rs12490466(TGFBR2),rs2009112(TGFB2)and rs4075748(TGFBR2)showed statistically significant SNP-SNP interaction(P＜1.46 × 10-4).In contrast,the analysis of gene-environment interactions did not yield any significant results after being cor-rected by multiple testing.Conclusion:The comprehensive evaluation of SNP associations and interac-tions within the TGF-β signaling pathway did not yield any direct associations with NSCL/P risk in Asian populations.However,the significant gene-gene interactions identified suggest that the genetic architec-ture influencing NSCL/P risk may involve interactions between genes within the TGF-β signaling path-way.These findings underscore the necessity for further investigations to unravel these results and further explore the underlying biological mechanisms.

Objective:To delve into the intricate relationship between common genetic variations across the entire genome and the risk of non-syndromic cleft lip with or without cleft palate(NSCL/P).Methods:Utilizing summary statistics data from genome-wide association studies(GW AS),a thorough investigation to evaluate the impact of common variations on the genome were undertook.This involved assessing single nucleotide polymorphism(SNP)heritability across the entire genome,as well as within specific genomic regions.To ensure the robustness of our analysis,stringent quality control measures were applied to the GWAS summary statistics data.Criteria for inclusion encompassed the absence of missing values,a minor allele frequency≥1％,P-values falling within the range of 0 to 1,and clear SNP strand orientation.SNP meeting these stringent criteria were then meticulously included in our analy-sis.The SNP heritability of NSCL/P was calculated using linkage disequilibrium score regression.Addi-tionally,hierarchical linkage disequilibrium score regression to partition SNP heritability within coding re-gions,promoters,introns,enhancers,and super enhancers were employed,and the enrichment levels within different genomic regions using LDSC(v1.0.1)software were further elucidated.Results:Our study drew upon GWAS summary statistics data obtained from 806 NSCL/P trios,comprising a total of 2 418 individuals from the Chinese population.Following rigorous quality control procedures,490 593 out of 492 993 SNP were deemed suitable for inclusion in SNP heritability calculations.The observed SNP heritability of NSCL/P was 0.55(95％CI:0.28-0.82).Adjusting for the elevated disease pre-valence within our sample,the SNP heritability scaled down to 0.37(95％CI:0.19-0.55)based on the prevalence observed in the general Chinese population.Notably,our enrichment analysis unveiled significant enrichment of SNP heritability within enhancer regions(15.70,P=0.04)and super enhan-cer regions(3.18,P=0.03).Conclusion:Our study sheds light on the intricate interplay between common genetic variations and the risk of NSCL/P in the Chinese population.By elucidating the SNP heritability landscape across different genomic regions,we contribute valuable insights into the genetic basis of NSCL/P.The significant enrichment of SNP heritability within enhancer and super enhancer re-gions underscores the potential role of these regulatory elements in shaping the genetic susceptibility to NSCL/P.This paves the way for further research aimed at uncovering novel genetic pathogenic factors un-derlying NSCL/P pathogenesis.

Objective To investigate the expression of programmed death ligand 1(PD-L1) in primary tumor cells(TCs) and tumor-infiltrating immune cells(TICs) in patients with liver metastases from colorectal cancer(CRC) and determine its predictive value for recurrence after microwave ablation(MWA) of liver metastases. Methods The paraffin-embedded specimens of 28 patients with CRC liver metastasis were collected retrospectively. The expression of PD-L1 in the primary lesions was detected by immunohistochemistry, and the relationship between PD-L1 and clinical features was analyzed. Recurrence-free survival(RFS) was analyzed by Kaplan-Meier method and Log rank test. Cox proportional hazards regression model was used to analyze the factors influencing recurrence. Results The positive rates of PD-L1 in TCs and TICs in primary CRC were 14.3%(4/28) and 46.4%(13/28), respectively. PD-L1 expression in primary TICs of CRC patients with liver metastases was significantly correlated with the largest hepatic tumor diameter (P < 0.05). PD-L1 expression in primary TICs of CRC patients with liver metastasis was correlated with poor RFS after MWA (P < 0.05). PD-L1 expression in primary TICs and the largest hepatic tumor diameter > 3 cm in CRC patients with liver metastases were the risk factors for recurrence after MWA (P < 0.05). Conclusion PD-L1 expression in primary TICs of CRC patients with liver metastasis may increase the risk of recurrence after MWA for liver metastasis.

Objective:To establish a risk prediction model for neonatal asphyxia in cesarean section and test its application effect.Methods:This was a retrospective study. We retrospectively analyzed the clinical data of 2 244 infants (modeling group) who were delivered by cesarean section in Affiliated Hospital of Weifang Medical University from April 2021 to December 2021. Newborns were divided into asphyxia group ( n=176) and non-asphyxia group ( n=2 068) according to the occurrence of neonatal asphyxia. Logistic regression was used to screen the risk factors of neonatal asphyxia in cesarean section and a line chart model was established to predict the risk. Another 683 neonates were selected as validation group for external validation of the model from January to March in 2022. Results:Five factors including preterm birth, fetal distress, fetal growth restriction, abnormal S/D value of umbilical artery and umbilical cord around the neck were included in the prediction model. The area under ROC curve of the modeling group was 0.902, the Youden index was 0.687, the sensitivity was 0.837, and the specificity was 0.850. Hosmer-lemeshow test showed that χ2=1.79, and P=0.877. In the validation group, the area under ROC curve was 0.823, the Youden index was 0.555, the sensitivity was 0.835, and the specificity was 0.720. It showed that the model had a good fitting effect and identification validity. Conclusions:The risk prediction model has a good clinical application value in the prediction of neonatal asphyxia in cesarean section, and provides reference for obstetricians to take preventive management measures of neonatal asphyxia in time.

Ganjiang (Zingiberis Rhizoma, ZR) and Jiangtan (Carbonized Zingiberis Rhizoma, CZR) have long been used in traditional Chinese medicine (TCM) with a rich history in the treatment of various ailments. While ZR and CZR obviously stem from the same botanical source, their attributes, chemical compositions, pharmacological behaviors, and clinical applications are different owing to variations in the extent of drying and processing they undergo. In this paper, data pertaining to ZR and CZR were retrieved from databases including China National Knowledge Infrastructure (CNKI), PubMed, Web of Science, and Google Scholar. These sources were scrutinized to elucidate the distinctions between ZR and CZR arising from carbonization processing in terms of their ethnopharmacology, quality control, chemical compositions, biological activities, pharmacological mechanisms, and clinical uses. In this study, a total of 56 chemical constituents were identified and isolated from ZR and CZR, which primarily encompassed volatile oils, gingerols, and diphenylheptane compounds. CZR's pharmacological effects include hemostatic, anti-oxidant, analgesic, antibacterial, anti-cancer, and other biological activities. ZR has pungent and warm properties. It is a Yang-supplementing herbal medicine for ailments exacerbated by cold or damp climatic influences. CZR is a product of ZR after undergoing high temperature, with diminished intensity of its pungent and warm attributes. This change leads to a more gradual treatment efficacy, renowned hemostatic effects and its ability to gently invigorate the spleen and effectively alleviate diarrhea. Currently, research on the pharmacological mechanism of CZR is mainly focused on the effects of CZR on coagulation and fibrinolysis. Although the healing effect of CZR has long been known, and some correlation has been found between the changing composition and the changing color of the decoctions, people still lack relatively clear processing mechanisms to reflect the characteristics and specific quality standards of the ingredients of CZR's hemostatic effect. This review provides a systematic summary on quality control, chemical composition, ethnopharmacology, and pharmacology of CZR, offering novel perspectives for advancing the exploration of additional carbonized herbal medicine and fostering their application in clinical settings

Objective:To discuss the classification and treatment of ureteroileal anastomotic stricture (UAS) after radical cystectomy.Methods:The clinical data of 34 patients with UAS after radical cystectomy in the Department of Urology of Tongji Hospital from January 2017 to January 2022 were reviewed and analyzed. There were 25 males and 9 females. The average age was (66.3±7.7)years, including 2 cases of bilateral hydronephrosis and 32 cases of unilateral hydronephrosis. The average time of UAS was detected (14.7±6.5)months after radical cystectomy. There were 32 patients of unilateral hydronephrosis and 2 patients of bilateral hydronephrosis. Two patients had undergone nephrostomy in an external hospital. Three patients had elevated leukocytes in blood routine. Among them, two patients had fever. First, nephrostomy on the hydronephrosis side and anti-infection treatment were performed. After routine blood tests showed that the white blood cells were normal and antibiotics were stopped for 24 hours without fever, the operation was performed. 34 patients had preoperative hydronephrosis of (2.7±0.6) cm. Of the 34 cases in this group, 5 cases were injected with methylene blue through a preoperative nephrostomy tube, and 29 were injected with methylene blue through the renal pelvis using an 18G puncture needle under ultrasound guidance. Using a ureteroscope to observe in the ileal bladder, methylene blue was seen in 4 cases. Methylene blue was used to guide the search for the stenosis and a super smooth guide wire was inserted. Among them, 3 cases were dilated with a 5 mm ureteral dilation balloon catheter, 1 case was dilated with a F14 ureteral access sheath, and then a F6 single J stent was inserted. Methylene blue was not seen in the ileal conduit in 30 cases, of which 16 cases were treated with a flexible ureteroscope through the nephrostomy to locate the stenosis, incised with a 30 W holmium laser. 9 cases were treated with 5 mm ureteral dilation balloon catheter, and 7 cases were treated with a F14 ureteral access sheath, and then an F6 single J stent was inserted. 14 cases were unable to find the stenosis by antegrade method. According to the operation time and patient's condition, it was decided to perform immediate or second stage dual endoscope surgery. Through the nephrostomy, a flexible ureteroscope was used to enter the stenosis along the super slide guide wire. A rigid ureteroscope was used to observe the stenosis through the ileal conduit, and the stenosis was found. The stenosis was found in 10 cases and incised with a 30 W holmium laser. 8 cases were treated with 5 mm ureteral dilation balloon catheter, and 2 cases were treated with a F14 ureteral access sheath, and then an F6 single J stent was inserted. 4 cases were still unable to accurately locate the stenosis using the dual endoscope surgery(one case was bilateral stenosis, and one side was relieved), and continued indwelling nephrostomy. The definition of successful removal of stricture in this study is that an F6 single J stent can be inserted into the ureter.Results:UAS were classified into four types based on the severity of the intraoperative findings: Type Ⅰ, the narrow ureteral lumen is more than 50% narrower than the normal ureteral lumen, but methylene blue can pass through in strands; Type Ⅱ, needle like stricture of the ureteral lumen, allowing only methylene blue filaments to pass through; Type Ⅲ, membranous atresia of the ureter, with a narrow segment of 1 to 3 mm in length, and methylene blue cannot pass through; Type Ⅳ, long segment stenosis. Of the 34 cases in this group, 4 cases were type Ⅰ, and the stenosis was dredged by retrograde method; 16 cases were type Ⅱ, and the stenotic segments were dredged by antegrade method; 10 cases were type Ⅲ, and the stenosis was dredged by the dual endoscope surgery; Four cases were of type Ⅳ (one case was of bilateral UAS, one side was of type Ⅲ, and the other side was of type Ⅳ, which was classified as type Ⅳ). The stenotic segment could not be solved through the above methods. Among the 34 patients, 30 patients were successfully relieved of anastomotic obstruction, and 1 patient with bilateral obstruction was unilaterally relieved of anastomotic obstruction. In the other 3 cases, because the stenosis segment was too long, 2 cases were changed to nephrostomy, and 1 case was changed to open surgery, with a success rate of 88.2%. UAS was classified into 4 types based on the severity of UAS seen during surgery. No serious complications occurred during and after the operation. During the follow-up of 6-24 months, the imaging evaluation of 4 patients showed that hydronephrosis was aggravated, with an average increase in creatinine of (32.5±10.9)μmol/L, requiring replacement of a single J tube. The imaging evaluation of the remaining 26 patients showed that the postoperative hydronephrosis was 0.9 ± 0.6 cm less than the preoperative hydronephrosis 2.6 ± 0.6 cm, with a statistically significant difference ( P<0.01). The quality of life score at 3 months after surgery was (1.9±0.6), which was significantly improved compared to the preoperative indwelling nephrostomy period (5.2±0.7), with a statistically significant difference ( P<0.01) Conclusions:The treatment of UAS after radical cystectomy with retrograde, antegrade, and dual endoscope surgery has a high success rate, which can help some patients avoid the inconvenience of indwelling external drainage tubes and the risk of open surgery. Choosing an appropriate surgical method can achieve the goal of treating UAS with minimal trauma.

Via an insufficient coat protein complex I (COPI) retrieval signal, the majority of SARS-CoV-2 spike (S) is resident in host early secretory organelles and a tiny amount is leaked out in cell surface. Only surface-exposed S can be recognized by B cell receptor (BCR) or anti-S therapeutic monoclonal antibodies (mAbs) that is the trigger step for B cell activation after S mRNA vaccination or infected cell clearance by S mAbs. Now, a drug strategy to promote S host surface exposure is absent. Here, we first combined structural and biochemical analysis to characterize S COPI sorting signals. A potent S COPI sorting inhibitor was then invented, evidently capable of promoting S surface exposure and facilitating infected cell clearance by S antibody-dependent cellular cytotoxicity (ADCC). Importantly, with the inhibitor as a probe, we revealed Omicron BA.1 S is less cell surface exposed than prototypes because of a constellation of S folding mutations, possibly corresponding to its ER chaperone association. Our findings not only suggest COPI is a druggable target against COVID-19, but also highlight SARS-CoV-2 evolution mechanism driven by S folding and trafficking mutations.

【Objective】 To reveal the integral in vivo polypharmacokinetics (PPK) similarity or difference between Jinyinhua (Lonicerae Japonicae Flos, LJF) and Shanyinhua (Lonicerae Flos, LF), and provide reference for their clinical application. 【Methods】 The PPK model and its total quantum statistical moment similarity (TQSMS) method were used to compare the integral PPK profiles of nine components with anti-inflammatory efficacy (rutin, caffeic acid, chlorogenic acid, cryptochlorogenic acid, dispsacoside B, macranthoidin B, isochlorogenic acid A, isochlorogenic acid B, and isochlorogenic acid C) of LJF and LF. A total of 54 Specific Pathogen Free (SPF) grade Kunming (KM) mice were randomized into LJF group and LF group (n = 27), and each group was divided into nine subgroups (n = 3) according to different time points. Subsequently, mice model of p-xylene-induced ear edema was constructed by oral administration of LJF and LF. The concentrations of the nine anti-inflammatory components in plasma samples of the mice were determined by ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS/MS). And the pharmacokinetics (PK) parameters of single component and the integral PPK parameters [total quantum statistical moment (TQSM) and TQSMS] of multiple components were calculated by Drug And Statistics (DAS) software and home-brew programs with Excel, respectively. 【Results】 There were significant differences in single-component PK parameters between LJF and LF (P < 0.05). Whereas, no significant differences were found in multi-component TQSM parameters, including total quantum zero moment (AUCT0-t, AUCT0-∞) and total quantum first moment (MRTT0-t, MRTT0-∞) for the total quanta (P > 0.05). Accordingly, single-component TQSMS varied from 0.220 4 to 0.968 9, and that for the total quanta was 0.828 4, suggesting no significant differences in the speed and extent of bioavailability between LJF and LF. Furthermore, in light of high TQSMS (0.828 4), the integral PPK profiles of the nine anti-inflammatory components of LJF and LF were similar under 90% confidence intervals. 【Conclusion】 The PPK model and its TQSMS method are appropriate and efficient to compare the similarity or difference of integral PPK profiles of multi-component herbal medicines. It is suggested in this research that LJF can be replaced with LF or vice versa for anti-inflammatory treatment.

To investigate the evaluation and management of gastrointestinal fistula after upper gastrointestinal tunnel endoscopic surgery, a retrospective analysis was performed on 15 patients with gastrointestinal fistula after upper gastrointestinal tunnel endoscopic surgery, who were treated at the Endoscopy Center of Zhongshan Hospital, Fudan University from January 2012 to October 2022. All patients were treated successfully after comprehensive treatment. Three patients received metal clipping and gastric tube drainage; 10 patients received gastric tube drainage combined with jejunal nutritional tube placement, and 7 of them had gastric tube directly put into the fistula cavity; 2 patients received covered esophageal stent placement combined with jejunal nutritional tube placement. Five patients received wound tissue glue spraying; 2 patients underwent purse-string suture with nylon loops and metal clips after reduced fistula burned by hot biopsy forcep or argon plasma coagulation. The gastrointestinal fistula after tunnel endoscopic surgery is a complex postoperative complication, which needs early detection, careful evaluation and comprehensive treatment.
