Objective To establish a comprehensive,simple,and effective scoring model for predicting the recurrence risk after endovascular embolization of intracranial aneurysms in order to assess the possibility of recurrence and to provide guidance for the selection of surgical protocols and postoperative management.Methods From May 2012 to May 2014,434 patients (441 aneurysms) with intracranial aneurysm treated with endovascular embolization at the Department of Neurosurgery,Changhai Hospital,the Second Military Medical University were enrolled retrospectively,and they were used as a modeling group.After modeling,109 patients (109 aneurysms) were used as a validation group.In the modeling cohort,a predictive scoring model of recurrence risk was established according to the results of multivariate logistic regression analysis;the model was validated in the validation cohort.According to the scoring model of the modeling group,the scoring table of best cut-off value of the receiver operating characteristic (ROC) curves was divided into a low-risk and a high-risk of recurrence.The recurrence risk score model was compared with the North America aneurysm recanalization stratification scale (ARSS) model,and Raymond grade.Results Multivariate logistic regression analysis showed that the 3 factors included in the scores and finally,a established scoring model of recurrence risk prediction were non-stent assisted embolization (1 point),Raymond grade ≥Ⅱ (1 point),and the size of aneurysm (aneurysm >25 mm[3 points)],aneurysm 10-25 mm[1 point],and aneurysm <10 mm[0 point]).The validation indicated that the scoring system had higher predictive value (AUC=0.738,95%CI 0.641-0.834,P<0.05) and goodness of fit (Hosmer-Lemeshow χ2=2.109,P=0.146).The scoring table was further divided into the low-risk recurrence (0-1 point) and high-risk recurrence (2-5 points),its sensitivity was 72.73% (48/66) and specificity was 68.80% (258/375).The predictive ability of the aneurysm recurrence risk score model was similar to that of the ARSS score (χ2=0.54,P=0.462),and it was better than the Raymond grade (χ2=15.10,P<0.01).Conclusion The established simple aneurysm recurrence risk predicting score model in this study may accurately predict the recurrence of aneurysms,however,a multicenter,large sample prospective study is needed for further validation.

Following oxidative stress, reactive oxygen species are produced and accumulate in glioma cells in large quantities, and to avoid the occurrence of cellular dysfunction, glioma cells can respond adaptively in the biological processes of DNA damage repair, lipid peroxidation and protein modification to produce radiotherapy resistance. The expression of nuclear factor erythroid 2-related factor 2, solute carrier family 7 member 11, glutathione and microRNA, as key regulatory molecules, can regulate reactive oxygen species levels, alter glioma oxidative stress status, and affect radiochemotherapy sensitivity. Further study on the relationship between oxidative stress and sensitivity to radiotherapy and chemotherapy of glioma can provide theoretical basis for precise treatment of glioma.

Abdominal internal hernia is relatively rare in clinics, which is easily to be ignored and occur serious complications, mainly the obstruction of gastrointestinal tract, such as gastrointestinal ischemia and necrosis, that could be life-threatening. This article introduced one case with atypical abdominal pain as the first manifestation of the disease, then the main symptom was metabolic acidosis and treatment was carried out, and finally by surgery the diagnosis of abdominal internal hernia was confirmed and proper treatment given.

Objective: To investigate the correlation of human papillomavirus (HPV) infection status and genotyping characteristics with the result of liquid-based thin-layer cytology (TCT) of the cervix in the female physical examiners in Xi'an. Methods: The data of 5 163 female physical examiners who underwent HPV and TCT screening simultaneously in the First Affiliated Hospital of Xi'an Jiaotong University From June 2017 to June 2018 were collected to analyze HPV infection, genotyping and their relationship with TCT. Results: Among the 5 163 examiners, 527 (10.21%) were HPV-positive, and the infection rate in the examiners over 60 years old was the highest [12.26% (57/465)]. Among HPV-positive examiners, the infection rate of single genotype was higher than that of multiple genotypes infection [75.90% (400/527) vs. 24.10% (127/527), P < 0.01]. The top four genotypes were type 52, 58, 53 and 16 accounting for 17.21% (121/703), 12.09% (85/703), 11.52% (81/703) and 10.67% (75/703), respectively, of the total frequency of HPV infection. Of the 5 163 examiners, 68 (1.32%) examiners were positive for TCT screening. There was no significant difference in the positive rate of TCT between HPV multiple genotypes-infected examiners and single genotype-infected examiners [11.02% (14/127) vs. 9.00% (36/400), χ² = 0.460, P > 0.05]. Among 50 examiners with positive results of HPV and TCT tests, the top four genotypes were type 58, 52, 53 and 16, and they were in consistence with the overall HPV infection genotyping. Conclusions The HPV infection in the female physical examiners in Xi'an is dominated by the single genotype infection, and the main genotypes of HPV infection are type 52, 58, 53 and 16. The combined detection of HPV genotyping and TCT can improve the effectiveness of cervical lesions screening.

Objective:To construct a nomogram for predicting the occurrence of renal allograft rejection based on the combination of multimodal ultrasound features and clinical data.Methods:The ultrasound findings and clinical characteristics of 102 patients with transplanted kidneys who underwent renal biopsy in the General Hospital of Eastern Theater Command from January 2021 to March 2022 were analyzed retrospectively. Patients were divided into rejection group and nephropathy group according to Banff transplant kidney pathological diagnostic criteria (2017 edition). Multivariate Logistic regression was used to screen independent predictors related to the status of rejection, and nomograms were drawn based on the independent predictors. The internal validation of the nomogram was carried out by Bootstrap method, and the ROC curve and calibration curve were utilized to evaluate the diagnostic efficacy of the nomogram.Results:Blood urea nitrogen concentration, renal aortic resistance index, absolute time to peak and cortical echo were independent predictors of rejection( OR=1.073, 1.078, 0.843, 0.205; all P<0.05). Incorporating blood urea nitrogen concentration, renal aortic resistance index, absolute peak time and cortical echo, the nomogram was constructed. The AUC of the predictive model was 0.814(95% CI=0.722-0.905) and the cutoff value was 0.67(corresponding to a total score of about 157 points). Both internal verification (AUC=0.788) and calibration curve demonstrated the clinical usefulness of the nomogram. Conclusions:The nomogram for predicting the occurrence of rejection in renal allograft patients based on multimodal ultrasound features and clinical data can guide the individualized treatment of patients with renal dysfunction.

Objective:To investigate the morphological feature and clinical significance of MRI around tumor after drug-eluting bead transcatheter arterial chemoembolization (DEB-TACE) of primary hepatocellular carcinoma.Methods:We reviewed and analyzed the data of hepatocellular carcinoma patients admitted from January 2017 to December 2018 in the Department of Radiological Intervention of the First Affiliated Hospital of Zhengzhou University. A total of 42 patients were enrolled, including 35 males and 7 females, aged (57.0±11.9) years. For the first time after operation, MRI enhancement showed peri-tumor margin enhancement as the starting point of follow-up. Follow-up and measure enhanced edge thickness, delayed enhancement, progression or remission data.Results:A total of 49 tumors and 84 peritumoral enhancement margins were included in 42 patients, with 30 sharp type , 40 rough type and 14 nodular type. The thickness of sharp type is less than that of rough type and nsodular type, and the differences were statistically significant (all P<0.05). The sharp type is the majority of the tumors with maximum diameter <5 cm, rough type and nodule type are the majority of tumors with maximum diameter ≥5 cm. Most of the sharp type are continuously enhanced, while the rough type and nodular type are not. Most sharp type relief (93.3%, 28/30), while rough type (80.0%, 32/40) and nodular type ( n=12) are mostly of deterioration, the differences are statistically significant (all P<0.05). Conclusion:Compared with the rough type and nodular type, the sharp type usually occurs in smaller tumors and more prone to local mitigation in the enhanced morphology around MRI after DEB-TACE in primary hepatocellular carcinoma.

Objective To analyze the clinicopathological features of type 2 diabetes mellitus complicated with colorectal cancer (DCRC). Methods A case?control study was conducted. Inclusion criteria: (1) hospitalized patients receiving fibrocolonoscopy; (2) adenocarcinoma and mucinous adenocarcinoma diagnosed by pathology; (3) with preoperative cTNM clinical staging; (4) colorectal cancer patients undergoing surgical treatment; (5) with postoperative pTNM staging; (6) no smoking or drinking habits. Exclusion criteria: (1) familial adenomatous polyposis (FAP); (2) Lynch syndrome; (3) carcinoma of anal canal and perianal carcinoma; (4) multiple primary cancer; (5) with serious cardiocerebrovascular diseases or multiple organ failure. Clinicopathlogical data of 32 DCRC patients who were diagnosed and treated in Peking University Shougang Hospital from December 2017 to December 2018 were retrospectively collected and analyzed. Forty nondiabetic colorectal cancer (CRC) patients during the same period were selected as control group according to the sex ratio and the age difference less than 5 years. Student′s t test and χ2 test were used to compare the difference between the two groups in baseline clinicopathological data, clinical test results, tumor markers and infiltration status of T cells in tumor immune microenvironment. Results Among 32 DCRC patients, 24 were males and 8 were females with a mean age of (63.0±1.7) years; among 40 CRC patients, 30 were males and 10 were females with a mean age of (60.5 ± 1.6) years. The duration of diabetes mellitus in DCRC patients (from the diagnosis of diabetes mellitus to the diagnosis of colorectal cancer) was (9.2±1.3) years. The body mass index (BMI) of DCRC group was significantly higher than that of CRC group [(24.8±0.6) kg/m2 vs. (23.2±0.4) kg/m2, t=2.372, P=0.020]. There were no significant differences in other baseline data (sex, age, primary site of tumor, R0 resection rate, pathological stage, pathological type, differentiation degree of tumor, preoperative intestinal obstruction) between the two groups (all P>0.05). Serum triglyceride level in DCRC group was higher than that in CRC group [(2.1 ± 0.2) mmol/L vs. (1.5 ± 0.1) mmol/L, t=3.085, P=0.003], while hemoglobin [(120.3±5.2) g/L vs. (132.7±2.8) g/L, t=-2.224, P=0.029], anti? thrombin III [(94.2±3.7)% vs. (103.5±2.4)%, t=-2.197, P=0.031], and red blood cell count [(4.2±0.1)×1012/L vs. (4.5±0.1)×1012L, t=-2.055, P=0.044] were all lower than those in CRC group. The preoperative carcinoembryonic antigen (CEA) level in DCRC group was higher than that in CRC group [(50.3±21.8) μg/L vs. (5.6±1.0) μg/L, t=2.339, P=0.022]. There were no significant differences in preoperative levels of other four tumor molecular markers (CA199, CA242, CA724 and CA125) between the two groups (all P>0.05). The expression of Foxp3 [specific markers of CD4+, CD25+ regulatory T cells (Treg)] in DCRC group was higher than that in CRC group [(82.7±6.2) cell/ HPF vs. (62.6±4.9) cell/HPF, t=2.586, P=0.012]. There were no significant differences in the infiltration of CD4, CD8, PD?1 and PD?L1 positive cells between two groups (all P>0.05).Conclusions The average diabetic history of DCRC patients is nearly 10 years. They have higher BMI and serum CEA level, and more Treg cell infiltration in the tumor. Close attention should be paid to these patients in clinical practice.

Objective:To investigate the safety and efficacy of the TRIANGLE operation after neoadjuvant chemotherapy in locally advanced pancreatic cancer(LAPC).Methods:This study is a retrospective case series analysis. Between January 2020 and December 2022, a total of 103 patients were diagnosed as LAPC who underwent neoadjuvant chemotherapy at the Pancreas Center, the First Affiliated Hospital of Nanjing Medical University. Among them, 26 patients (25.2%) underwent the TRIANGLE operation. There were 15 males and 11 females,with a age of (59±7) years (range: 49 to 74 years). The pre-treatment serum CA19-9( M(IQR)) was 248.8(391.6)U/ml (range: 0 to 1 428 U/ml),and the serum carcinoembryonic antigen was 4.1(3.8)μg/L(range: 1.4 to 13.4 μg/L). The neoadjuvant chemotherapy regimens included: mFOLFIRINOX regimen in 6 cases(23.1%), GnP regimen in 14 cases(53.8%), and mFOLFIRINOX+GnP regimen in 6 cases(23.1%). The follow-up duration extended until June 2023 or until the occurrence of the patient′s death or loss to follow-up. The Kaplan-Meier method was employed to estimate the 1-year and 3-year overall survival rates. Results:After neoadjuvant chemotherapy,CA19-9 levels decreased by 92.3(40.1)%(range:2.1% to 97.7%). Evaluation of the response to treatment revealed 13 cases(50.0%) of stable disease,11 cases(42.3%) of partial response,and 2 cases(7.7%) of complete response. The surgical operation consisted of 12 cases(46.2%) of pancreaticoduodenectomy,12 cases(46.2%) of distal pancreatectomy,and 2 cases(7.7%) of total pancreatectomy. Margin determination was based on the “standardised pathology protocol” and the “1 mm” principle. No R2 and R1(direct) resections were observed,while the R0 resection rate was 61.5%(16/26), and the R1(1 mm) resection rate was 38.5%(10/26).The R1(1 mm) resection rates for the anterior margin,posterior margin,transected margin,portal vein groove margin,and uncinate margin were 23.1%(6/26),19.2%(5/26),12.5%(3/24),2/14, and 1/12, respectively. The overall postoperative complication rate was 57.8%(15/26),with major complications including grade B/C pancreatic fistula 25.0%(6/24,excluding 2 cases of total pancreatectomy),delayed gastric emptying in 23.1%(6/26),wound complications 11.5%(3/26),postoperative hemorrhage 7.7%(2/26), chylous fistula 7.7%(2/26) and bile fistula 3.8%(1/26). No reoperation was performed during the perioperative period(<90 days). One patient died on the 32 nd day postoperatively due to a ruptured pseudoaneurysm. A total of 25 patients were followed up,with a follow-up time of 21(24)months(range: 8 to 42 months). During the follow-up period,8 cases(32.0%) died due to tumor recurrence and metastasis,while 17 patients(68.0%) remained alive,including 11 cases of disease-free survival,5 cases of distant metastasis,and 1 case of local recurrence. The overall survival rates at 1- and 3-year after the initiation of neoadjuvant chemotherapy were 95.8% and 58.9%, respectively. The overall survival rates at 1- and 3-year after surgery were 77.7% and 57.8%, respectively. Conclusion:Performing pancreatoduodenectomy according to the Heidelberg triangle protocol in LAPC patients after neoadjuvant chemotherapy might increase the R0 resection rate without increasing perioperative mortality or the incidence of major postoperative complications.
