Objective Based on the U.S.Food and Drug Administration Adverse Event Reporting System(FAERS)database,data mining was conducted on hematological adverse events related to antibody drug conjugates(ADC),providing reference for the safe use of ADC drugs in clinical practice.Methods The report data from the third quarter of 2011 to the fourth quarter of 2022 were retrieved from the FAERS database.After data cleaning such as deduplication and name standardization,extract hematological adverse events related to ADC,and use report odds ratio method and the information component method for signal detection.Results A total of 101 610 adverse event reports were extracted,with 8 ADC drugs as the primary suspected drugs,and 5 768 ADC related hematological adverse event reports.Among them,3 423 cases of agranulocytosis were involved,and the signal intensity from strong to weak were sacituzumab govitecan(SG),gemtuzumab ozogamicin(GO),brentuximab vedotin(BV),polatuzumab vedotin(PV),enfortumab vedotin(EV),trastuzumab deruxtecan(TD),inotuzumab ozogamicin(IO)and ado-trastuzumab emtansine(TDM-1).There were 2 327 cases hematopoietic cell deficiency,with signals ranging from strong to weak were IO,SG,BV,EV,PV,TD,TDM-1,and GO.Report with clinical outcome of death of ADC drug related hematological adverse events included BV 179(16.84％),TDM-1 102(13.01％),TD 88(27.08％),GO 12(16.90％),IO 8(11.59％),EV 54(24.32％),PV 22(27.16％),and SG 84(21.05％).Adverse event time analysis showed that the number of events on the first day of TD,IO,and SG medication accounts for ≥ 40％of the total number of cases.The median time of hematological adverse events in TD,GO,IO,EV,PV,and SG was within one treatment course(21 days).Conclusion Attention should be paid to the risk of ADC drug-related hematological adverse event,during the clinical medication process,blood cell count changes should be closely monitored,and any abnormalities should be promptly diagnosed and treated.

Chemical cleaning and disinfection are crucial steps for eliminating infection in root canal treatment.However,irrigant selection or irrigation procedures are far from clear.The vapor lock effect in the apical region has yet to be solved,impeding irrigation efficacy and resulting in residual infections and compromised treatment outcomes.Additionally,ambiguous clinical indications for root canal medication and non-standardized dressing protocols must be clarified.Inappropriate intracanal medication may present side effects and jeopardize the therapeutic outcomes.Indeed,clinicians have been aware of these concerns for years.Based on the current evidence of studies,this article reviews the properties of various irrigants and intracanal medicaments and elucidates their effectiveness and interactions.The evolution of different kinetic irrigation methods,their effects,limitations,the paradigm shift,current indications,and effective operational procedures regarding intracanal medication are also discussed.This expert consensus aims to establish the clinical operation guidelines for root canal irrigation and a position statement on intracanal medication,thus facilitating a better understanding of infection control,standardizing clinical practice,and ultimately improving the success of endodontic therapy.

This study was aimed at investigating the effect of lymphocyte activation gene-3(LAG3)on liver B lymphocyte subsets and their functions in WT and LAG3-KO mice infected with Echinococcus multilocularis(E.multilocularis).In a mouse model of E.multilocularis infection,the expression and localization of CD19 and α-SMA in liver were detected by immu nohistochemistry.CD80,CD86 and MHC-Ⅱ molecules expressed on B cells and their subsets in mice liver were detected by flow cytometry.After 12 weeks of infection,the area and percentage of CD19 in LAG3-KO group was slightly higher than that in WT group,but the difference was not statistically(t=-1.241、-1.237,P＞0.05).The area and percentage of a-SMA in LAG3-KO group was higher than that in WT group(t=-3.224、-3.227,P＜0.05).The proportion of CD80 and MHC-Ⅱ molecules expressed on liver B cells in LAG3-KO group was up-regulated(t=-2.379,-3.321,P＜0.05).The percentage of liver B2 cells in LAG3-KO group was higher than that in WT group(t=-2.695,P＜0.05).The expression of CD80 on Blb cells in LAG3-KO group was significantly up-regulated(t=-5.315,P＜0.001).The proportion of CD80 of B2 cells in LAG3-KO group was lower than that in WT group(t=2.806,P＜0.05).The expression of MHC-Ⅱ molecule in B2 cells in LAG3-KO group was up-regulated(t=-4.227,P＜0.01).It is suggested that LAG3 molecules affected the B cell subsets and func-tion of mouse liver in the middle stage of E.multilocularis infection,especially B2 lymphocytes.LAG3 molecule exerted an in-hibitory effect on the activation of B cells and the expression of MHC-class Ⅱ molecules,suggesting that it may be involved in B cell exhaustion caused by E.multilocularis.

The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators' insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.

Objective:To investigate the therapeutic effect of open suture and selective suture in patients with high complexity anal fistula and its effect on anal function and complications.Methods:Prospectively selected 174 patients with high complex anal fistula who were hospitalized in the Anorectal Surgery Department of the Second People′s Hospital of Yibin City from December 2018 to December 2021 as the study subjects, including 138 males and 36 females, aged from 26 to 45 years, with an average of (35.20 ± 8.86) years. According to the admission order of patients, grouped them into single and double numbers, with single numbers being the control group ( n=87) and double numbers being the observation group ( n=87). The control group was treated with traditional incision and thread hanging therapy, while the observation group was treated with selective suture through incision and thread hanging therapy. Compared the surgical time, blood loss, surgical cost, wound healing time, and anal function at 6 months after surgery between the two groups of patients. Compared the treatment effects of two groups of patients at 6 months after surgery. Compared the postoperative complications within 6 months and recurrence within 1 year between the two groups. The measurement data subject to normal distribution were expressed by mean ± standard deviation( ± s). The two groups were compared by independent sample t test, and the count data were compared by Chi-square test. Rank sum test was used for comparison of hierarchical data. Results:The surgical time in the observation group was higher than that in the control group [(44.30 ± 8.11) min vs (42.18 ± 7.25) min, ( t=-2.44, P<0.05], and the surgical cost was higher than that in the control group [(1184.81 ± 372.68) yuan vs (835.28 ± 320.03) yuan, t=-8.75, P<0.001]. There was no statistically significant difference in blood loss data between the two groups [(19.57 ± 6.07) mL vs (18.35 ± 5.25) mL, t=-1.88, P>0.05]. The length of wound healing time in the observation group was lower than that in the control group [(24.18 ± 4.35) d vs (29.35 ± 5.08) d, t=11.09, P<0.001]. The anal function score of the observation group at 6 months after surgery was lower than that of the control group [(4.80 ± 1.21) score vs (6.71 ± 1.35) score, t=14.72, P<0.001]. All patients did not experience any loss of follow-up. In the comparison of treatment effects 6 months after surgery, the observation group had a better efficacy rating than control group ( Z=3.86, P<0.001). At 6 months after surgery, the incidence of complications in the observation group was lower than that in the control group [2.30% (2/87) vs 10.34% (9/87), χ2=4.76, P<0.05]. One year after surgery, the recurrence rate in the observation group was lower than that in the control group [2.30% (2/87) vs 10.34% (9/87), χ2=4.76, P<0.05]. Conclusion:The application of incision and thread-drawing selective suture in the treatment of patients with high complex anal fistula is beneficial to the treatment effect of patients, reduces postoperative complications, and protects the anal function of patients, with good use value.

ObjectiveTo clarify the value of the left ventricular longitudinal strain（LVLS）parameters in patients with cardiac amyloidosis （CA） and primary hypertension with left ventricular hypertrophy （HLVH）. MethodsForty-one patients confirmed with CA were selected and assigned to CA with hypertension group （n =14） and pure CA group （n=27） based on the initial diagnosis with or without hypertension. Twenty patients with primary hypertension-induced left ventricular hypertrophy （HLVH group） and twenty healthy controls were also selected， matching for gender， age， and body surface area. Clinical data， conventional echocardiography parameters were collected and LVLS parameters were measured. Within-group variations were compared among the four groups， and pairwise comparisons were conducted between groups. The sensitivity and specificity of each parameter in predicting CA were judged by the receiver operator characteristic （ROC） curvy in CA and HLVH patients with left ventricular ejection fraction （LVEF） preserved. ResultsAmong the conventional echocardiography parameters， LVEF and left ventricular end-diastolic diameter （LVEDD） were lower in the CA with hypertension group and pure CA group compared with the higher values in the HLVH group and control group. Whereas， left ventricular posterior wall thickness （LVPWT）， relative wall thickness （RWT）， and average E/e' were higher in the two CA groups compared with the HLVH group （all P＜0.05）.Among the LVLS parameters， Global longitudinal strain （GLS） was the worst in the CA with hypertension group so as pure CA group， modest in the HLVH group， and highest in the control group. On the contrary， relative longitudinal strain and ejection fraction strain ratio （EFSR） were the highest in the CA with hypertension group so as to pure CA group， modest in the HLVH group， and lowest in the control group （all P＜0.05）. ROC analysis showed that when LVEF was preserved， the absolute value of GLS less than 14.35% and EFSR higher than 4.28 could effectively distinguish CA from HLVH （all AUCs＞0.9，all P＜0.05）； meanwhile GLS showed high sensitivity（100%） and EFSR showed great specificity（95%）. There were not statistically significance in any parameter between CA with hypertension group and pure CA group（all P＞0.05）. ConclusionWhether CA was complicated with hypertension or not， there were statistically significance among routine echocardiography and LVLS parameters compared with HLVH. In particular， GLS and EFSR are accurate in predicting CA in patients with myocardial hypertrophy and preserved LVEF.

Acupoint-symptom relationship in CHENG Dan-an's Note About Treatise on Cold-Attack was analyzed based on complex network, acupoint names and indications were extracted from the book, which provided ideas and methods for promoting the modernization of acupuncture and moxibustion by using complex network technology. A total of 112 acupoints in 201 acupuncture prescriptions were included, and the total frequency of acupoints was 880 times, forming 42 034 acupoint pairs. In terms of network indexes, compared with the complex network of comprehensive acupuncture books, such as Meridian and Acupoint Science, Zhenjiu Dacheng, Acupuncture A and B Meridians formed based on the same mathematical method, the complex network model for CHENG Dan-an's Note About Treatise on Cold-Attack shows more typical small world effect, which is characterized by higher network density (6.762) and shorter average path length (1.064). This phenomenon may be related to the tongue and pulse which added the link between acupoints. For the node indexes, the analysis of topological indexes such as Page Rank shows that acupoints represented by Dazhui (GV 14) has higher compatibility value in the treatment of exogenous diseases, which further demonstrates the clinical value of eigenvector centrality in guiding intelligent compatibility of points.

ObjectiveTo investigate the morphological characteristics of mitral valve annulus in patients with degenerative mitral valve prolapse with severe regurgitation. MethodsA total of 18 patients with mitral valve prolapse complicated with severe regurgitation and 36 patients with normal mitral valve were selected and analyzed using Philips Epic7C echocardiography equipped with transesophageal 3D probe X7-2T and QLAB MVN software. ResultsThe anterolateral and posterio-medium diameter， anterior-posterior diameter， circumference and area of mitral annulus in patients with mitral prolapse complicated with severe regurgitation were larger than those in the control group （P<0.05）. In addition， the annulus parameters in the middle and late systole were higher than those in the early systole （P<0.05）， while the height of the mitral annulus and the non-planar angle showed no difference between the two groups or among different cardiac cycles （P>0.05）. ConclusionsThe three-dimensional morphology and functional of mitral valve annulus changed dynamically with different phases of cardiac cycle. Three-dimensional esophageal echocardiography could provide accurate and detailed information for degenerative mitral valve prolapse with regurgitation.

Since 2015 when the transmission of schistosomiasis was controlled in China, the country has been moving towards elimination of schistosomiasis, with the surveillance-response as the main interventions for schistosomiasis control. During the period of the 13th Five-Year Plan, the transmission of schistosomiasis had been interrupted in four provinces of Sichuan, Jiangsu, Yunnan and Hubei and the prevalence of schistosomiasis has been at the historically lowest level in China. As a consequence, the goal set in The 13th Five-Year National Schistosomiasis Control Program in China is almost achieved. However, there are multiple challenges during the stage moving towards elimination of schistosomiasis in China, including the widespread distribution of intermediate host snails and complicated snail habitats, many types of sources of Schistosoma japonicum infections and difficulty in management of bovines and sheep, unmet requirements for the current schistosomiasis control program with the currently available tools, and vulnerable control achievements. During the 14th Five-Year period, it is crucial to consolidate the schistosomiasis control achievements and gradually solve the above difficulties, and critical to provide the basis for achieving the ultimate goal of elimination of schistosomiasis in China. Based on the past experiences from the national schistosomiasis control program and the challenges for schistosomiasis elimination in China, an expert consensus has been reached pertaining to the objectives, control strategy and measures for The 14th Five-Year National Schistosomiasis Control Program in China, so as to provide insights in to the development of The 14th Five-Year National Schistosomiasis Control Program in China.
