Objective:To evaluate laparoscopic choledocholithotomy in patients with cholecystolithiasis and normal sized common bile duct(CBD) with choledocholithiasis.Methods:The clinical data of 393 patients with cholecystolithiasis and choledocholithiasis treated by LC combined with LCBDE at the Department of General Surgery of Hefei Second People's Hospital from Mar 2014 to Jul 2021 were retrospectively analyzed.Results:There were 280 CBD calculi cases in which CBD diameter >8 mm which was included into CBD dilated group, and 113 cases of CBD calculi with normal diameter (5 mm≤CBD diameter ≤8 mm). There was no difference in operative time and postoperative complications in the small diameter group. During the follow-up period, 1 case in the dilated group experienced biliary tract stenosis and treated by stenting. There was no statistical significance in biliary tract stenosis in both groups ( P>0.05).Stone recurrence occurred in 3 cases (2.7%) in the normal diameter group, all of which were removed by ERCP lithotomy. Stone recurrence occurred in 8 cases (2.9%) in the CBD dilated group, 7 were removed by ERCP stone extraction and 1 refused further treatment. Conclusion:It is safe and feasible to perform LC+LCBDE in patients with cholecystolithiasis complicating normal sized CBD stones.

Objective:
To investigate the expression,prognosis and biological role of hepatocyte nuclear factor 4A (HNF4A) in gastric cancer,and to study its effect on the proliferation of gastric cancer cells.
Methods:
Tumor Immune Estimation Resource 2. 0 (TIMER2. 0) and Gene Expression Profiling Interactive Analysis ( GEPIA2) databases were used to analyze the relative expression levels of HNF4A in gastric cancer and normal tissue,KM Plotter was used to analyze the correlation between the expression level of HNF4A and the survival rate of gastric cancer patients,TISIDB database and R language (4. 1. 2) were used to analyze whether HNF4A was involved in the immune regulation process of gastric cancer.cBioPortal database was used to analyze the mutations of HNF4A in gastric cancer,GSEA 4. 2 was used to analyze the functional enrichment of HNF4A,and LinkedOmics database was used to predict the genes that might be regulated by HNF4A.The relative expression of HNF4A in gastric cancer and adjacent tissues was detected by qRT-PCR , Western blot and immunohistochemistry (IHC) .The proliferation and cell cycle of gastric cancer cells were analyzed by CCK-8,EdU,colony forming assay and flow cytometry.
Results :
The expression of HNF4A increased in gastric cancer tissues (P <0. 05) ,and the overall survival rate of gastric cancer patients with high HNF4A expression was worse (P<0. 001) .HNF4A was mainly missense mutated in gastric cancer.Immune cell infiltration showed that HNF4A was associated with B lymphocytes,CD8 + T cells, neutrophils,macrophages and dendritic cells ( all P <0. 001) . HNF4A was also associated with tumor mutation burden (r = 0. 28,P<0. 0001) and microsatellite instability (r = 0. 13,P<0. 01) .After knockdown of HNF4A, cell proliferation ability was significantly inhibited ,and cell cycle was arrested at G0 / G1 phase.
Conclusion
HNF4A expression significantly increased in gastric cancer tissues,which is associated with poor prognosis ,and may also be involved in immune regulation. Knockdown of HNF4A can inhibit the proliferation of gastric cancer cells.

Antibody-drug conjugates(ADCs), as an emerging therapy for cancer treatment, have made significant progress in the past few decades. However, due to the heterogeneity of ADCs, they still face various issues and challenges in clinical therapy. Therefore, site-specific conjugation techniques have become a crucial area of research in ADCs, and in recent years, this field has witnessed numerous breakthrough advancements, empowering ADCs with enhanced performance. The review provides a comprehensive overview of the frontiers in site-specific conjugation technologies for ADCs. Categorized into seven major classes including lysine-based, cysteine-based, low-abundance amino acid-based and glycosylation site-based conjugation techniques, ribosomal incorporation of unnatural and noncanonical amino acids and enzyme-mediated conjugation techniques, it meticulously describes 21 classical and emerging techniques such as the THIOMAB technology and linchpin-directed modification, in order to offer valuable insights for the development of next-generation ADCs.

Objective:To evaluate the effect of imatinib on growth impairment in children with chronic myeloid leukemia (CML-CP) in the chronic phase.Methods:From July 2018 to July 2019, questionnaires were distributed to CML children aged <18 years at the time of diagnosis who were receiving imatinib for at least 3 months or to their parents in China. The height-for-age standard deviation score (HtSDS) and the difference of standard deviation integral (△HtSDS) were used to explore the change in height with imatinib therapy.Results:The data of 238 respondents were included; 138 (58.0% ) respondents were men. The median age at the first diagnosis of CML was 11.0 years (range, 1.4-17.9 years) , and 93 (39.0% ) respondents were at the prepuberty stage. At the time of completing the questionnaires, the median age was 15.0 years (range, 2.0-34.0 years) . The median duration of imatinib therapy was 28 months (range, 3-213 months) . Among all the respondents, the mean HtSDS when completing the questionnaires (-0.063±1.361) was significantly lower than that at the time of starting imatinib treatment (0.391±1.244) ( P<0.001) . Total 71.0% respondents showed growth impairment that was more common in those starting imatinib therapy at prepubertal age than in those starting at pubertal age. Multivariate analysis showed that younger at the start of imatinib therapy ( P<0.001) and longer duration of imatinib therapy ( P<0.001) were significantly associated with severe growth impairment on imatinib therapy. Conclusions:Imatinib induced growth impairment in children with CML-CP. Younger the age of initiation and longer the duration of imatinib therapy, more obvious the effect of imatinib on growth impairment.

OBJECTIVE:
To investigate the relationship between sleep parameters and suicidal ideation in patients with late-life depression (LLD).
METHODS:
Seventy-seven LLD patients over 60 years old from Sir Run Run Shaw Hospital of Zhejiang University during July 2017 and July 2018 were included in the study. All patients were assessed with Hamilton Depression Rating Scale (HAMD) and polysomnography (PSG) overnight. The suicidal score of item 3 in HAMD (HAM-D3)was used to define whether there was a suicidal ideation. Participants were subsequently grouped according to endorsement of presence (HAM-D3 score ≥1, =46) versus absence (HAM-D3 score=0, =31) of suicidal ideation symptoms. The sleep efficiency, total sleep time, wakefulness after sleep onset, rapid eye movement percent/latency, and non-rapid eye movement sleep stages 1-3 (N1-N3) were assessed. ANOVA analyses were conducted to explore the correlation of sleep parameters with suicidal ideation between the groups with and without suicidal ideation. In model 1, the HAM-D3 constituted the independent variable in separate ANOVA tests; in model 2 the impact of depressive symptoms were assessed as a covariate with sleep parameters.
RESULTS:
There was less stage N3 [(55±41)min, =-4.731, <0.05] and the reduced percentage of N3 [(15±11)%, =-4.194, <0.05] in LLD patients with suicidal ideation, compared with the LLD patients without suicidal ideation [(104±49) min, (26±11)%]. Correlation analyses revealed that there was a significant correlation between the suicidal ideation and the percentage of stage N3 and sleep time of stage N3 (both <0.05).
CONCLUSIONS
Suicidal ideation is associated with less N3 sleep in LLD patients.
