ObjectiveTo explore the risk factors of recurrence of incisional hernia following incisional hernia tension-free repair. MethodsThe clinical data of 162 patients with incisional hernia underwent tension-free repair were retrospectively analyzed in this hospital from January 2005 to January 2011. The relationships of incisional hernia recur-rence to gender, age, body mass index, hernia size, abdominal wall defect site, preoperative chronic comorbidities, type of tension-free repair, operation time, and wound healing disorders were analyzed by univariate and multivariate analysis. ResultsOne hundred and sixty-two patients were followed up 7-70 months with mean 34.5 months. The rate of recur-rence following incisional hernia tension-free repair was 9.26% (15/162). The results of univariate analysis showed that recurrence following incisional hernia tension-free repair was associated with the age (P < 0.05), body mass index (P < 0.05), type of tension-free repair (P < 0.05), hernia size (P < 0.05), and wound healing disorders (P < 0.05). The results of multivariate logistic regression revealed that the body mass index, type of tension-free repair, hernia size, and wound healing disorders were the independent risk factors associated with recurrence following incisional hernia tension-free repair. Fifteen recurrent patients were reperformed successfully. There was no recurrence following up with an average 23 months. ConclusionsIt is necessary to become familiar with the risk factors for recurrence of incisional hernia in order to eliminate or decrease their effects on the positive outcome of incisional herniorrhaphy. The patients with fat, hernia ring bigger, incorrect opera-tion or wound healing disorders might be easy to relapse. Surgical approach should be individualized for recurrence.
ObjectiveTo compare clinical outcomes between coronary artery bypass grafting (CABG)and off-pump coronary artery bypass grafting (OPCAB)for high-risk coronary artery disease (CAD)patients with high European System for Cardiac Operative Risk Evaluation (EuroSCORE). MethodsA total of 211 CAD patients undergoing surgical treatment in the Department of Cardiovascular Surgery, Anhui Provincial Hospital Affiliated to Anhui Medical University from June 2007 to July 2013 were enrolled into this study, including 52 patients receiving CABG and 159 patients receiving OPCAB. Predicted risk of operative mortality (PROM)of each patient was calculated by EuroSCORE. Patients with PROM≥6 were stratified into high-risk subgroups. Clinical outcomes were compared between CABG and OPCAB patients, as well as incidence of cardiovascular events, angina and stroke within 30 postoperative days in high-risk subgroup patients. ResultsOPCAB and CABG group patients had similar left main disease. There was no statistical difference in the number of distal anastomosis between OPCAB (2.75±0.82)and CABG group patients (2.83±0.58) (P > 0.05). Operation time[ (3.92±0.79)hour vs. (6.83±1.53)hour], thoracic drainage[ (983.14±802.39)ml vs. (1 620.40±879.32)ml], blood transfusion[ (1 289.30±668.08)ml vs. (2 325.30±491.98)ml], length of ICU stay[ (3.90±1.33)days vs. (5.08±1.78)days], and mechanical ventilation time[ (9.63±3.32)h vs. (13.76±3.79)h] of OPCAB group patients were significantly shorter or lower than those of CABG group patients (P < 0.05). There was no statistical difference in 30-day mortality between OPCAB and CABG group patients (1.26% vs. 3.85%, P > 0.05). Among high-risk subgroup patients, the odds ratio of stroke within 30 postoperative days in CABG was 5.7 (95%CI 1.28-25.09, P < 0.05)compared with OPCAB group patients, and the incidence of cardiovascular events and angina within 30 postoperative days were similar between the 2 subgroups. ConclusionsPostoperative mortality and number of distal anastomosis are not significantly different between CABG and OPCAB patients, but OPCAB can significantly reduce operation time, thoracic drainage, blood transfusion, length of ICU stay and mechanical ventilation time compared with CABG. For high-risk patients with high EuroSCORE, OPCAB can better reduce the incidence of postoperative stroke compared with CABG.

ObjectiveTo summarize the research progress of correlation between pancreatic cancer and diabetes mellitus.MethodsRecent studies on the association between pancreatic cancer and diabetes mellitus were extensively reviewed, and relevant research results on the association between pancreatic cancer and diabetes mellitus were reviewed.ResultsPancreatic cancer had a particular association with diabetes. Patients with pancreatic cancer may develop new diabetes or worsen existing diabetes mellitus. About 50% of patients with pancreatic cancer had diabetes mellitus before diagnosis, suggesting a “dual causal relationship” between pancreatic cancer and diabetes mellitus. Long-term type 2 diabetes mellitus (T2DM) was one of the high risk factors for the occurrence and development of pancreatic cancer. T2DM may also increase the risk of pancreatic cancer due to hyperinsulinemia, adipokine, and other factors. Pancreatic cancer was one of the cause of diabetes mellitus at the same time, but its mechanism was not yet known, also needed to get a lot of information to understand the impact of long-term diabetes mellitus on the development of pancreatic cancer, as well as the reason of pancreatic cancer related to diabetes mellitus mechanism.ConclusionThe clear relationship between pancreatic cancer and diabetes mellitus has not been proved, and further research is needed to clarify the relationship between them.
ObjectiveTo analyze the relation between ABO blood type and postoperative pathological features of patients with colorectal cancer served by West China Hospital of Sichuan University as a regional center in the current version of Database from Colorectal Cancer (DACCA). MethodsThe data of DACCA was updated on January 5, 2022. According to the screening conditions, the enrolled patients with colorectal cancer were divided into blood type A, B, AB, and O. The differences in the postoperative pathological characteristics of patients with different blood types, such as pathological TNM, T, N, M (pTNM, pT, pN, pM) staging, peripheral nerve involvement, high risk factors, tumor regression grade (TRG), and cancer nodules, were analyzed. ResultsAfter screening, 6 089 data rows were analyzed. The patients involved 2 058 blood type A, 1 469 blood type B, 494 blood type AB, and 2 068 blood type O. The results of statistical analysis showed that: ① There were statistical differences in the overall distribution of pTNM and pM stages among the patients with different blood types (H=11.564, P=0.009; H=7.947, P=0.047), which was reflected in: from the overall distribution trend, the proportion of patients with the four blood types in the same stage was similar, but it could still be seen that patients with blood type AB accounted for the highest proportion in the patients with stage Ⅲ, Ⅳ, M1a, M1b as compared with other blood types. ② There were no statistical differences in the overall distribution of peripheral nerve involvement and TRG in the patients with different blood types (H=3.414, P=0.332; H=1.143, P=0.767). ③ There was statistical difference in the proportion of different grades of high risk factors in the patients with different blood types (H=14.540, P=0.002). Specifically, the proportions of patients with grade 3–5 of high risk factors in the patients with AB blood type were the highest. ④ There was no statistical difference in the proportion of the grade of cancer nodules number in patients with different blood types (H=4.460, P=0.216). ConclusionsFrom results of this study, it is found that there are some differences in pTNM stage, pM stage, and high risk factors of colorectal cancer patients with different blood types, but no differences in pT stage, pN stage, peripheral nerve involvement, TRG, and cancer nodules among different blood types of patients. The influence of blood type on postoperative pathological characteristics of colorectal cancer patients needs to be further explored.
ObjectiveTo analyze the relation between age and postoperative pathological features of patients with colorectal cancer from Database from Colorectal Cancerr （DACCA）. MethodsThe data in DACCA were updated on January 5, 2022. The patients were selected from DACCA according to the established screening conditions, then were divided into ≤35, 35–59, and ≥60 years old groups. The differences of postoperative pathological （p） TNM （pTNM）, pT, pN, pM stages, perineural invasion （PNI）, high-risk factors grade, and tumor regression grade （TRG） among the three age groups were analyzed, and the correlation between them was analyzed. ResultsAfter screening, 5 628 data rows were enrolled, of whom 196 patients were <35 years old, 2 382 patients were 35–59 years old, and 3 050 patients were >59 years old. Statistical analysis showed that: ① There were statistical differences in the proportions of pN stage, PNI, and high-risk factors grade in the patients of different age groups （H=27.867, P<0.001; H=6.248, P=0.044; H=19.712, P<0.001, respectively）; However, it was not found that there were statistical differences in the proportions of pTNM, pT, pM stages, and TRG after neoadjuvant therapy among different age patients （H=0.920, P=0.631; H=4.923, P=0.085; H=2.272, P=0.321; H=2.337, P=0.311, respectively）. The Spearman correlation analysis results showed that there was a weakly negative correlation between the age and pN stage or grade of high-risk factors （rs=–0.070, P<0.001; rs=–0.067, P<0.001, respectively） and a weakly positive correlation between age and TRG after neoadjuvant therapy （rs=0.100, P=0.009）. ConclusionDACCA data analysis finds that patients of different age groups shows a negative correlation trend with pN stage or grade of high-risk factors and a positive correlation trend with TRG, which needs to be further verified.
Objective To observe the high-risk histopathological feature (HRF) and their correlation with prognosis in children with intraocular retinoblastoma (RB) in the intraocular stage after failed eye-preserving treatment and enucleation surgery. MethodsA single-center retrospective case study. From August 2018 to January 2023, 64 children (64 eyes) with advanced intraocular RB who were diagnosed in Department of Ophthalmology of Beijing Children's Hospital and underwent enucleation surgery after failed eye-preserving treatment were included in the study. The median follow-up time was 51 months. The gender of the children patients, the age of visit and enucleation, International Intraocular Retinoblastoma Classification (IIRC), the initial chemotherapy regimen (hereinafter referred to as "chemotherapy"), the time of enucleation surgery, pathological results, post-enucleation treatment methods and prognosis were collected. The Mann-Whitney U test was used for comparison between groups. Survival analysis was performed using the Kaplan-Meier method, and the log-rank test was used for comparison between groups. ResultsAmong 64 cases and 64 eyes, 37 were male and 27 were female. The age of seeking medical treatment was 20 (11-31) months. The age at which the surgery was performed was 29 (16-40) months. The number of eyes in IIRC stage D and E was 16 and 48 respectively. The initial chemotherapy regimens simply applied (hereinafter referred to as "alone") intravenous systemic chemotherapy (IVC) and ophthalmic artery infusion chemotherapy (IAC) in 40 cases and 11 cases, 13 cases of IVC+IAC. All patients with positive HRF received systemic adjuvant chemotherapy after surgery. There were 37 eyes (57.8%, 37/64) positive for HRF. There was no statistically significant difference in the positive rate of HRF between children in IIRC stage D and stage E (χ2=0.021, P=0.884). Among the 37 eyes with HRF, the numbers of eyes with extensive choroidal invasion, posterior lamina cribrosa optic nerve invasion, scleral invasion and optic nerve stump involvement were 17 (45.9%, 17/37), 16 (43.2%, 16/37), 3 (8.1%, 3/37) and 3 (8.1%, 3/37), respectively. During the follow-up period, there were 5 cases (7.8%, 5/64) of extraocular metastasis of the tumor and death, all of which were stage E and had HRF. Among them, the initial treatment plan was IAC for 4 cases, one case of IVC. The survival rates of children among the IVC, IAC or IVC+IAC regimens were 97.5% (39/40), 63.6% (7/11), and 100.0% (13/13), respectively. The comparison of survival rates among different chemotherapy regimens showed statistically significant differences (χ2=14.233, P＜0.001). The results of survival analysis showed that the cumulative survival rate of those with extensive choroidal invasion, posterior lamina cribrosa optic nerve infiltration, and those who received IAC was significantly lower than that of those without extensive choroidal invasion, posterior lamina cribrosa optic nerve infiltration, and those who received IVC+IAC and IVC (P＜0.05). ConclusionsEye-preserving treatment for children with advanced intraocular RB may increase the positive rate of HRF and the risk of extraocular metastasis. The IVC+IAC eye-protecting treatment plan can improve the survival rate of children.
Objective To investigate the medication adherence to antihypertensives, antidiabetics, and lipid-lowering agents and its influence on the prognosis of individuals at high risk of stroke. Methods A total of 16892 residents aged 40 years or above in eight communities in Sichuan participated in a face-to-face study from May to September 2015. A database of a high-risk population of stroke in Sichuan province was established, and data were collected via using a standardized structured questionnaire by experienced investigators, including the treatment status and medication compliance of participants with hypertension, diabetes, or dyslipidemia during the follow-up period. Multiple logistic regression analyses were performed to explore the influencing factors of medication adherence and its influence on the prognosis of individuals at high risk of stroke. Results A total of 2893 participants at high risk of stroke were enrolled. The treatment rates of hypertension, diabetes, and dyslipidemia were 50.1%, 49.2%, and 5.1%, respectively, when the high-risk individuals were identified. At the end of follow-up (with a median follow-up period of 4.8 years), the treatment rates of hypertension, diabetes, and dyslipidemia were 24.8%, 25.0%, and 7.9%, respectively. Medication adherence to antihypertensives, antidiabetics, and lipid-lowering agents were 27.8%, 25.5%, and 18.1%, respectively. Multiple logistic regression analyses showed that the education level of high school or above [odds ratio (OR)=2.134, 95% confidence interval (CI) (1.098, 4.147), P=0.025], medical insurance for urban residents [OR=1.556, 95%CI (1.086, 2.230), P=0.016] and urban employees [OR=2.325, 95%CI (1.362, 3.967), P=0.002], having fewer children [OR=0.819, 95%CI (0.719, 0.933), P=0.003], and family history of stroke [OR=1.559, 95%CI (1.066, 2.282), P=0.022] were associated with greater adherence to antihypertensives; medical insurance for urban employees was associated with greater adherence to antidiabetics [OR=2.494, 95%CI (1.173, 5.300), P=0.018]. After adjusting for confounding factors, failure to regular use of antihypertensives [OR=2.617, 95%CI (1.414, 4.842), P=0.002], antidiabetics [OR=3.909, 95%CI (2.394, 6.380), P<0.001], and lipid-lowering agents [OR=4.828, 95%CI (2.581, 9.033), P<0.001] in patients with hypertension, diabetes, and dyslipidemia, respectively were associated with increased risk of ischemic stroke during the follow-up period. Regular use of lipid-lowering agents in patients with dyslipidemia was associated with an increased risk of intracerebral hemorrhage during the follow-up [OR=4.371, 95%CI (1.156, 16.530), P=0.030]. Conclusions The prevalences of hypertension, diabetes, and dyslipidemia are high in high-risk individuals of stroke in Sichuan province. However, the treatment rates are unsatisfactory, and the medication adherence is poor. The medication adherence is affected by a variety of demographic and socioeconomic factors. Regular treatments of hypertension, diabetes, and dyslipidemia reduce the risk of ischemic stroke in individuals at high risk of stroke, but regular use of lipid-lowering agents in patients with dyslipidemia is associated with an increased risk of intracerebral hemorrhage during the follow-up.
ObjectivesTo classify the high risk population for primary liver cancer (PLC) in rural China.MethodsBetween June 2011 and June 2013, hepatitis B surface antigen (HBsAg) carriers were identified in clinical laboratory of Qidong People’s Hospital and surveyed by questionnaires. Cox proportional hazard regression model was introduced to demonstrate independent risk factors associated with PLC occurrence. Moreover, receiver characteristic operating (ROC) curve was utilized to evaluate discrimination power of risk factor panel for PLC risk classification.ResultsA total of 1 296 HBsAg carriers were enrolled, among which 686 participants were male with an average age of 45.73±11.58 years, and 610 participants were female with an average age of 45.67±12.33 years. After a mean follow up period of 5.5 years, 43 incident PLC cases were confirmed, which generated a PLC incidence of 60.5 millions person years. Multi-univariate Cox model showed that increase of age (HR=1.055, 95%CI 1.029 to 1.083, P<0.000 1), male (HR=3.263, 95%CI 1.567 to 6.796,P=0.001 6), having family history of PLC (HR=2.315, 95%CI 1.260 to 4.252, P=0.006 8), HBeAg positivity (HR=2.367, 95%CI 1.267 to 4.419, P=0.006 9) and GGT abnormality (HR=2.721, 95%CI 1.457 to 5.083, P=0.001 7) were the independent risk factors of PLC.ConclusionRoutine host, viral and liver biochemical parameters which are readily accessible in daily clinical practice can be utilized in identification of the targeted population for prevention of PLC in rural China.
