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 evaluate the pathological features of bilateral retinoblastoma (RB) and the relationship between different treatments and high-risk histopathologic features (HHF). MethodsRetrospective series of case studies. From 1999 to 2018, 73 patients with binocular RB diagnosed by pathological examination in Department of Ophthalmology, Peking University People's Hospital were included in the study. Among them, 50 patients were male (68.5%, 50/73), 23 patients were females (31.5%, 23/73); 11 patitents had a family history of RB. The mean age at the first diagnosis was 14.8±15.6 months. The average time between first diagnosis and first intervention was 3.97±4.74 months. According to the international classification standard of intraocular RB staging, among the 73 eyes, C, D and E stages were 2 (2.7%, 2/73), 15 (20.5%, 15/73), and 56 (76.7%, 56/73) eyes, respectively. Ocular images for each patient were obtained using a wide-angle contact fundus camera during examination under general anaesthesia. The treatment protocol (globe salvaging or enucleation) depended on the result of several clinical features. Globe salvaging treatment included chemotherapy combined with local therapy such as intra-arterial chemotherapy (IAC), intravitreal chemotherapeutics injection, cryotherapy, laser, transpupillary thermotherapy and radiotherapy. If globe salvaging failed, enucleation was offered and histopathologic analysis was conducted of the enucleated eye, the ophthalmic pathologist read and evaluated the presence of HHF. Independent samples t-test was performed to compare the continuous variables. The pathological features and the relationship between different treatments and HHF were analyzed. Group difference was calculated with chi-square. Results Among the 73 eyes, the first treatment was enucleation in 21 eyes (28.8%, 21/73); 52 eyes (71.2%, 52/73) were treated with eye protection. After enucleation, 9 cases (12.3%, 9/73) had recurrence and metastasis, and 7 cases (9.6%, 7/73) died. The intervention time of patients with recurrence and metastasis and those without recurrence and metastasis were 7.4±7.3 and 3.5±4.1 months respectively; the first intervention time of patients with recurrence and metastasis was significantly later than that of patients without recurrence and metastasis, but the difference was not statistically significant (t=－1.561, P=0.154). The pathological examination results showed that there were 26 eyes (35.6%, 26/73) with HHF, 4 (26.7%, 15/26) and 22 (39.3%, 22/56) eyes were in stage D and E, respectively. Those who received other treatments before enucleation had lower HHF percentages after enucleation than those who did not receive corresponding treatments, but the difference was not statistically significant (χ2=1.852, 0.074, 0.000, 1.007, 0.007, 2.729; P＞0.05). Among the 26 eyes, 5 (83.3%, 5/6) and 21 (31.3%, 21/67) eyes were treated with systemic chemotherapy combined with and without IAC, respectively, and there was a significant difference in the percentage of HHF (χ2=4.422, P=0.035). ConclusionsIAC eye-preserving therapy before enucleation has a significant effect on HHF.
Objective To investigate the risk factors for early progression in patients with acute respiratory distress syndrome (ARDS), and to provide a reference for early detection and intervention of high-risk patients with ARDS progression. Methods Data from multicenter mechanically ventilated patients with mild to moderate ARDS were retrospectively analyzed. According to the severity grade of 72 h ARDS, the patients were divided into an early progressive group and a non-progressive group. Chi-square test was used to compare the risk factors of ARDS patients and the prognosis of the two groups were analyzed by Logistic regression. Results A total of 355 patients with mild to moderate ARDS were included in invasive mechanical ventilation, of which 97 patients (27.3%) progressed after 72 hours. 78.4% were female in the progressive group and 64.0% were female in the non-progressive group. Compared with the non-progressive group, the patients with ARDS in the progressive group had shorter 28-day no mechanical ventilation, higher ICU mortality, and lower survival rate at 30 days and 60 days（P<0.05）, but there was no significant difference in the length of ICU stay between the two groups (P>0.05). Univariate and multivariate regression analysis showed that the patients with ARDS in the progressive group had lower baseline oxygenation index (OR=0.979, 95%CI 0.961 - 0.986, P<0.01), higher peak airway pressure (OR=1.068, 95%CI 1.017 - 1.121, P<0.01), higher lactate level (OR=1.224, 95%CI 1.057 - 1.417, P<0.01), higher tidal volume (OR=1.159, 95%CI 1.002 - 1.341, P<0.05), higher age (OR=1.373, 95%CI 1.051 - 1.082, P<0.01), and more male patients (OR=2.583, 95%CI 1.336 - 4.995, P<0.05). Conclusions Early progression is common in mild to moderate ARDS patients with mechanical ventilation. The progressive group has shorter duration of 28 days without mechanical ventilation, higher ICU mortality and lower 30-day and 60-day survival rate than the non-progressive group. Male, low baseline oxygenation index levels, high peak airway pressure, tidal volume, lactate levels, and higher age are risk factors for early progression in patients with mild to moderate ARDS.

Methods We retrospectively analyzed the clinical data of 2 559 patients who underwent non-gastroduodenal abdominal surgeries in our hospital between September 2004 and March 2010. We divided them into the PGS group with 23 patients and the non-PGS group with 2 536 patients. Results By comparing the age, the gender, the starting time of eating after surgery, the duration of surgery, whether the patients had advanced cancer, whether anemia or hypoproteinemia existed, whether the patients had a history of previous abdominal surgery, and whether nutritional support was provided early after operation between the PGS group and the non-PGS group, we found that the chi-square value was 19.687, 0.018, 0.346, 48.243, 21.801, 16.803, 24.679, 0.870 and the P value waslt;0.01, gt;0.05, gt;0.05, lt;0.01, lt;0.01, lt;0.01, lt;0.01, gt;0.05 respectively. Conclusion Over 65 years of age, the duration of surgery over four hours, advanced cancer, the history of previous abdominal surgery and anemia or hypoproteinemia are the risk factors of PGS after non-gastroduodenal abdominal surgery.
ObjectiveTo study the efficacy and safety of early laparoscopic cholecystectomy with percutaneous transhepatic gallbladder drainage (PTGBD) in the treatment of elderly patients with high risk moderate acute cholecystitis.MethodsThe clinical data of 218 elderly patients with high risk moderate acute cholecystitis admitted to Department of Hepatobiliary Surgery in Dazhou Central Hospital from January 2015 to October 2019 were retrospectively analyzed, including 112 cases in the PTGBD combined with early LC sequential treatment group (sequential treatment group) and 106 cases in the emergency LC group. In the sequential treatment group, PTGBD was performed first, and LC was performed 3–5 days later. The emergency LC group was treated with anti infection, antispasmodic, analgesia, and basic disease control immediately after admission, and LC was performed within 24 hours. The operation time, intraoperative blood loss, conversion to laparotomy rate, postoperative catheter retention time, postoperative anal exhaust time, postoperative hospitalization time, hospitalization cost, incidence of incision infection, and incidence of complications above Dindo-Clavien level 2 were compared between the two groups to evaluate their clinical efficacy and safety.ResultsAll patients in the sequential treatment group were successfully treated with PTGBD, and the symptoms were significantly relieved within 72 hours. There were significant differences in the operation time, intraoperative blood loss, conversion to laparotomy rate, postoperative tube retention time, postoperative anal exhaust time, postoperative hospitalization time, incidence of incision infection, and the incidence of complications above Dindo-Clavien level 2 between the two groups (P<0.05), which were all better in the sequential treatment group, but the hospitalization cost of the sequential treatment group was higher than that of the emergency LC group (P<0.05). There were no cases of secondary operation and death in the 2 groups. After symptomatic treatment, the symptoms of all patients were relieved, without severe complications such as biliary injury and obstructive jaundice. All the 218 patients were followed up for 4–61 months, with an average of 35 months. During follow-up period, 7 patients in the sequential treatment group had postoperative complications, and complications were occurred in 13 patients in the emergency LC group.ConclusionPTGBD is the first choice for elderly high risk moderate acute cholecystitis patients with poor systemic condition and high risk of emergency surgery, but it has the disadvantage of relatively high medical cost.
ObjectiveTo analyze the risk factors of postoperative cognitive dysfunction (POCD) in elderly patients after abdominal surgery. MethodsThe clinical data of 2 286 patients over 60 years old after abdominal surgery were retrospectively analyzed, which were divided into non-POCD group with 2 248 patients and POCD group with 38 patients. The influencing factors of POCD in elderly patients after abdominal surgery, including the age, gender, anesthetic way, the premedication, cormobided with lung or heart disease, diabetes, jaundice, anemia or hypoproteinemia, the duration of surgery, and postoperative analgesia protocols, were analyzed between two groups. ResultsThe age, anesthetic way, cormobided with lung or heart disease, diabetes, jaundice, with or without continuous postoperative effective analgesia, and surgery duration over four hours were relevant with POCD (Plt;0.05), while gender, the premedication, and preexisted anemia or hypoproteinemia were not relevant with that (Pgt;0.05). ConclusionAge over 70 years, general anaesthesia, cormobided with lung or heart disease, diabetes, jaundice, surgery duration over four hours, and incomplete postoperative analgesia are the risk factors of POCD after abdominal surgery.
