ObjectiveTo investigate the feasibility and safety of endoscopic retrograde cholangiopancreatography （ERCP） combined with oral cholangiopancreatography in the treatment of major duodenal papilla gallbladder polyps. MethodsA retrospective analysis was performed for the clinical data of eight patients with choledocholithiasis and gallbladder polyps who underwent ERCP and combined with oral cholangiopancreatography for major duodenal papilla cholecystectomy in Center of Digestive Endoscopy， Jilin People’s Hospital， from May 2022 to June 2024， and related data were collected， including the success rate of surgery， the technical success rate of gallbladder polyp removal， the superselective method of cystic duct， the time of operation， the time of gallbladder polyp removal， and surgical complications. ResultsBoth the success rate of surgery and the technical success rate of gallbladder polyp removal reached 100%， and of all eight patients， three patients used guide wire to enter the gallbladder under direct view， while five patients received oral cholangiopancreatography to directly enter the gallbladder. The time of operation was 51.88±12.34 minutes， and the time of gallbladder polyp removal was 23.13±10.94 minutes. The diameter of gallbladder polyp was 2‍ ‍—‍ ‍8 mm， and pathological examination showed inflammatory polyps in three patients， adenomatous polyps in one patient， and cholesterol polyps in four patients. There were no complications during or after surgery. The patients were followed up for 2‍ ‍—‍ ‍27 months after surgery， and no recurrence of gallbladder polyp was observed. ConclusionOral cholangiopancreatography is technically safe and feasible in endoscopic major duodenal papilla cholecystectomy.

OBJECTIVE To explore the role of Yes-associated protein(YAP)in epidermal stem cell(EPSC)differentiation after ionizing radiation(IR).METHODS ① A punch was used to induce skin injuries on the back of mice.The IR group received localized irradiation with 60 Co γ-rays,while the normal control group did not.Samples were collected at 0,1,3,6,9,and 12 d for RNA and protein extraction.Western blotting was used to detect changes in YAP protein expressions during wound healing.Real-time quantitative polymerase chain reaction(RT-qPCR)was performed to assess the mRNA levels of Yap and its downstream target genes,connective tissue growth factor(Ctgf),and cysteine-rich protein 61(Cyr61).② EPSCs were exposed to 60 Co γ at a dose of 4 or 8 Gy,while the control group was not irradiated.Cells were collected to detect the levels of YAP protein via Western blotting.Cells were collected at 4,12,24,and 36 h post-IR to assess the levels of YAP mRNA by RT-qPCR.③ Short hairpin RNA(shRNA)was used to establish stable YAP knockdown cell lines,and the knockdown efficiency of sh YAP was verified by Western blotting.RT-qPCR was then performed to detect the impact of YAP knockdown on mRNA levels of K1 and K10 after IR.RESULTS① Compared with the control group,the YAP protein level in the IR group during wound healing was significantly reduced(P<0.05,P<0.01),so were the mRNA levels of Yap and its downstream target genes Ctgf and Cyr61(P<0.05,P<0.01).② Compared to the cell control group,the mRNA and protein levels of YAP in the IR group cells were significantly reduced(P<0.01).③ In the sh YAP cells,the YAP protein level was significantly reduced(P<0.01).Furthermore,the mRNA levels of K1 and K10 were significantly decreased after IR in sh YAP cells(P<0.01).CONCLUSION YAP can regulate EPSC differentiation in wound healing after IR.

Objective:To evaluate the safety and efficacy of enhanced recovery after surgery(ERAS) in the perioperative period of congenital choledochal cysts in children.Methods:This is a multicenter prospective randomized controlled study. The clinical data of 273 pediatric congenital choledochal cysts(CCC) patients who underwent surgery at 14 medical centers with complete follow-up data were collected through the medical data analysis platform. Among them, 123 cases in ERAS group were managed perioperatively in strict accordance with ERAS mode, and 150 cases in conventional group were managed according to traditional mode. The length of hospital stay,time to first farting, time to complete feeding, the incidence of complications, cost and readmission rate within 30 days,stress indexes and liver function were compared between the two groups.Results:Compared with the conventional group, median time to start farting (2.0 d vs. 3.0 d, P<0.001), median time to complete feeding (5.0 d vs. 7.0 d, P<0.001), median postoperative hospitalization time (6.0 d vs. 9.0 d, P<0.001),the median total length of stay(13.0 d vs. 15.0 d, P<0.001) were shorter,the median hospitalization cost (37,000 yuan vs.43,000 yuan P<0.001) was lower, and stress indexes recovered quickly. The incidence of postoperative hospital stay and readimission rate within 30 d were not statistically different between the two groups. Conclusion:It is safe and feasible to implement ERAS for children with CCC in the perioperative period, which can reduce stress response, speed up recovery,and save medical costs.

Objective:To explore the role of ductular reaction in assessing the efficacy of liver transplantation.Method:From January 2015 to December 2020, he relevant clinical data were retrospectively reviewed for 100 recipients and their corresponding donors at Shulan (Hangzhou) Hospital. They were assigned into two groups of hepatic steatosis (HS group, 65 cases) and non-hepatic steatosis (non-HS group, 35 cases) according to whether or not receiving steatosis donated liver. Furthermore, based upon the occurrence of early allograft dysfunction (EAD), the participants were categorized into two groups of EAD (33 cases) and non-EAD (67 cases). The degree of bile duct reaction ductular reaction was defined by the percentage of staining area occupied by cytokeratin 19 (CK19) -positive bile duct cells in immunohistochemical-stained specimens. Donor of ductular reaction were compared between HS/non-HS and EAD/non-EAD groups. The risk factors for EAD were identified by univariate and multivariate Logistic regression analysis. Subgroup analysis was conducted based upon the level of ductular reaction (DR number) in donors (DR=0.4 as a threshold) and whether or not donors exhibited steatosis. The impact of DR was examined on the incidence of EAD and survival post-liver transplantation in steatosis donors.Result:The level of DR was higher in steatosis donor than that in non-steatosis donor [ (0.59%±0.385%) vs. (0.32%±0.194%), P<0.01]. And it was higher in EAD group than that in non-EAD group [ (0.72%±0.449%) vs. (0.38%±0.226%), P<0.01]. Multivariate logistic regression analysis showed that a high level of ductular reaction was an independent risk factor for EAD post-liver transplantation in donor. Subgroup analysis revealed that receiving a steatosis donor with low ductular reaction (DR<0.4%) had comparable levels of EAD occurrence and overall survival rate to receiving a non-steatosis donor. Conclusion:Steatosis with low ductular reaction donor may be safely applied for liver transplantation. And assessing donor injury based upon ductular reaction can effectively expand the clinical application of steatosis donors.

Objective:To assess the usage of the robot-assisted core-needle biopsy for the bone tumors, moreover to compare its outcomes with the manual technique.Methods:A retrospective study was conducted from February 2019 to February 2021, the medical records of the patients with bone lesions that had received core-needle biopsy were collected. There were 57 males and 45 females, the age was 45.9 (10~79) years. Eight patients received robot-assisted biopsy, whereas 94 patients underwent C-arm/ CT guided biopsy, the recorded data included operational duration, aspirational direction adjustment, etc. The pathological diagnosis reports of the biopsy specimens and the operational specimens were compared.Results:The diagnosis outcomes included metastases (33 cases), osteosarcoma (12 cases), chondrosarcoma (12 cases), giant cell tumor of bone (12 cases), fibrous dysplasia (7 cases), chronic osteomyelitis (7 cases), lymphoma (4 cases), multiple myeloma (4 cases), chronic fracture (3 cases), chondroblastoma (2 cases), pleomorphic undifferentiated sarcoma (2 cases), leiomyosarcoma (1 case), and Langerhans cell histiocytosis (1 case). Eighty-seven cases (85.29 %) lesions were found in the limbs, whereas 15 cases (14.71%) were in the axial locations. Compared with the manual group, the robot-assisted group had more axial locations: 7/8 vs. 11.70%(11/94), P<0.01; fewer aspirational direction adjustment: (0.4 ± 0.1) times vs. (3.1 ± 1.5) times, P<0.01 ; longer operational duration: (48.8 ± 8.8) min vs. (29.6 ± 6.0) min, P<0.01. There were no statistical differences between the two groups regarding the sex, age, pathological fracture, diagnostic accuracy, open biopsy rate and complications ( P>0.05). Conclusions:The robot-assisted core-needle biopsy is a reliable technique, it helps decrease the operational difficulty. The usage of this technique is recommendable for the bone lesions with great difficulty for biopsy, such as the minimal bone tumors and the lesions in the spine and the pelvis.

Objective:To explore the differences in clinical and injured vertebra radiological parameters between patients with non-traumatic osteoporotic vertebral compression fracture (OVCF) and those with traumatic OVCF after percutaneous vertebroplasty (PVP).Methods:A retrospective study was conducted to analyze the 369 OVCF patients (with 458 vertebrae injured) who had been treated by PVP at Department of Orthopaedics, Beijing Luhe Hospital between October 2015 and March 2017. There were 292 females and 77 males with a mean age of 73 (60, 79) years. Based on the absence or presence of a trauma history, the patients were stratified into a non-traumatic group (127 patients with 160 vertebrae injured) and a traumatic group (242 patients with 298 vertebrae injured). Clinical parameters [age, gender, body mass index, symptomatic duration, and number of injured vertebrae, visual analogue scale (VAS), Oswestry disability index (ODI), duration of follow-up, and rate of new OVCFs] and injured vertebra radiological parameters (position of injured vertebra, fracture type, compression severity, fracture range, cortical defect, intravertebral cleft, spinal canal compromise, basivertebral foramen, morphology of bone cement, range of bone cement, cement leakage, cement volume, rate of vertebral height restoration, recollapse of cemented vertebrae) were recorded perioperatively. All the clinical and radiological parameters were compared between the 2 groups.Results:Compared with the traumatic group, the non-traumatic group had an older age [75 (71, 83) years versus 71 (65, 76) years], more females (85.0% versus 76.0%), a longer symptomatic duration [10.0 (7.0, 15.0) d versus 6.5 (2.0, 12.0) d], a lower preoperative VAS pain score [7 (6, 8) points versus 7 (7, 8) points], a lower VAS pain score at postoperative day 1 [2 (2, 3) points versus 2 (2, 3) points], a lower preoperative ODI [66% (63%, 72%) versus 70% (65%, 73 %)], a lower ODI at postoperative day 1 [32% (30%, 34%) versus 32% (31%, 34%)], a higher rate of new OVCFs during follow-up (34.6% versus 12.8%), a lower rate of thoracolumbar lesions (51.9% versus 70.1%), more deformed fractures (mostly amphicoelous type), a lower rate of cortical defects in the anterior wall (20.0% versus 31.5%), a higher rate of trabecular pattern of cement (83.1% versus 71.8%), a higher rate of type-B cement leakage (50.6% versus 31.9%), a lower rate of type-C cement leakage (5.6% versus 12.8%), a lower rate of recollapse of cemented vertebrae (43.8% versus 55.4%). All the comparisons above were statistically significant ( P<0.05). There were no significant differences between the 2 groups in the other clinical or radiological parameters ( P>0.05). Conclusions:There are statistically significant differences in a significant number of clinical and injured vertebra radiological parameters between patients with non-traumatic OVCF and those with traumatic OVCF after PVP. It is noteworthy that non-traumatic OVCFs are one specific subgroup of OVCFs.

Objective To explore the relevant relationship and specificity between the implicit and explicit loyalty of military cadets in order to provide a theoretical basis and objective indicators for a more comprehensive and objective assessment for individual loyalty.Methods E-Prime 2.0,a classic implicit association paradigm was employed to construct an implicit association loyalty test for 64 military cadets.Simultaneously,an explicit loyalty measurement was conducted using the Chinese Military Personnel Loyalty Scale.Results ① Significant implicit effect was observed in the loyalty assessment of military cadets,indicating a general tendency to perceive higher levels of personal loyalty and lower levels of loyalty to external entities.② Explicit loyalty assessment revealed that the participants had the highest loyalty score towards the Party,the Nation,and the People(4.79±0.34),followed by the loyalty score to their profession(4.38±0.53),and the relatively lower loyalty score towards the unit and leaders(4.03±0.83).Among the 3 dimensions of loyalty,the normative loyalty score ranked highest,while continuance loyalty score took lower.③ There were no correlations among the scores of loyalty to the Party,the Nation,and the People(r=-0.030,P=0.823),to the profession(r=-0.047,P=0.728),to the unit(r=0.050,P=0.710),or to the leaders(r=0.043,P=0.749).Conclusion The implicit effect in the loyalty assessment is significant in military cadets,and there is no significant correlation between explicit and implicit loyalty measurements.Thus,we cannot rely solely on explicit measurements to assess their loyalty attitudes.

Objective To explore the application value of CT texture analysis for evaluating Ki-67 expression in patient with esophageal squamous cell carcinoma.Methods Sixty-one cases of pathologically confirmed esophageal squamous cell carcinoma patients were selected to obtain the Ki-67 protein expression status of the patients'pathological tissues,and the patients were divided into a high-expression group and a low-expression group.All patients underwent plain and enhanced chest CT within two weeks before surgery.Lesions delineation and texture feature extraction of esophageal cancer were obtained via Omni-Kinetics software.The texture parameters included Min Intensity,Max Intensity,Median Intensity,Mean Intensity,Deviation,Skewness,Kurtosis,Entropy,Energy,Correlation,Haralick,short run high grey level emphasis(SRHGLE),short run low grey level emphasis(SRLGLE),long run high grey level emphasis(LRHGLE),long run low grey level emphasis(LRLGLE),Grey Level Nonuniformity,Run Length Nonuniformity.The differences of texture features among different Ki-67 expression groups were compared,and the receiver operating characteristic(ROC)curve was used to analyze the predictive value of Ki-67 expression in patient with esophageal cancer.Results In plain CT images,the SRHGLE and Grey Level Nonuniformity of the high expression group were significantly higher than those of the low expression group(P=0.010,0.002,respectively).In enhanced CT images,the Mean Intensity,Entropy and Grey Level Nonuniformity of the high expression group were significantly higher than those of the low expression group(P=0.026,0.037,0.001,respectively),and SRHGLE and LRHGLE of the high expression group were significantly lower than those of the low expression group(P=0.016,0.010,respectively).The area under the curve(AUC)of texture features in plain CT were 0.676-0.740,and the AUC of combined diagnosis reached 0.770[95%confidence interval(CI):0.645,0.868],and sensitivity and specificity was 0.921,0.565,respectively.In enhanced CT,the AUC of texture features were 0.629-0.750,the AUC of combined diagnosis increased to 0.903(95%CI:0.799,0.964),and sensitivity and specificity was 0.816,0.826,respectively.Conclusion CT texture analysis can early and non-invasively predict Ki-67 expression in patient with esophageal squamous cell carcinoma,it can be used as an imaging marker to evaluate the proliferative activity of esophageal cancer cells,and may provide diagnosis and treatment information for clinical decision-making of esophageal squamous cell carcinoma.

Acute idiopathic maculopathy(AIM)is an inflammatory lesion of unknown cause that primarily affects the macula. It follows a unique natural course, distinct from other maculopathy, often manifesting as a sudden loss of visual acuity followed by flu-like symptoms that gradually resolve as the disease subsides. A comprehensive understanding of the unique history, multimodal imaging, and a thorough systematic examination are crucial in determining the final diagnosis of AIM. The treatment and prognosis of AIM remain controversial. Meanwhile, it presents similar clinical manifestations and pathological changes to various chorioretinopathy, posing challenges for clinical differentiation. This article provides a review of its pathogenesis, clinical symptoms, multimodal imaging features, diagnosis and differential diagnosis, treatment and prognosis, in order to reduce misdiagnosis and mistreatment while enhancing comprehension of AIM.
