Objective To summarize the recent pathogenetic researches on the acute pancreatitis. Methods Relevant references about the pathogenesis of acute pancreatitis, which were published recently domestic and abroad were collected and reviewed. Results Recent experimental data indicated that the synthesis and release of pro-inflammatory cytokines and chemotactic factors were responsible for local injury and systemic dissemination of the inflammatory mediators. Experimental studies also provided evidences implying that the immune system might play a role in the development of pancreatitis, such as the activation of lymphocyte and neutrophil. Additionally, the pancreas may completely recover or become fibrotic after an attack of acute pancreatitis and the presence of pancreatic stellate cell was known as a crucial factor in the fibrogenesis. Conclusion The pathogenesis of acute pancreatitis is very complicated, the factors that determine the ultimate severity of the attack are still unknown.
ObjectiveTo investigate the needs for health education in chronic hepatitis B patients, in order to provide a theoretical basis for taking pertinent nursing intervention. MethodsBetween July and December 2011, self-made questionnaires on the needs for health education were used to investigate 70 in-patients with chronic hepatitis B. Meanwhile, factors associated with the needs of health education such as age, education, and the course of the disease were also analyzed. ResultsThe differences in the needs of health education were statistically significant among patients with different cultures, ages, and courses of disease (P<0.01). The needs of health education were correlated with culture, age and courses of disease. ConclusionThere are some deficiencies in the health education for chronic hepatitis B patients. In clinical practice, health education should be multidimensional and continuous based on the age, education degree and the course of the disease.
ObjectiveTo compare effectiveness of single-anastomosis duodenoileal bypass with sleeve gastrectomy (SADI-S) and single anastomosis sleeve ileal (SASI) bypass on weight loss and glucose regulating as well as difference in micronutrient deficiency in obese rats with type 2 diabetes mellitus. MethodsThirty-six Spraque-Dawley rats fed with high fat diet combined with intraperitoneal injection of low-dose streptozotocin (35 mg/kg) for 1 month were used to induce obese rats with type 2 diabetes mellitus, then were randomly averagely divided into 3 groups: SADI-S group, SASI group, and sham operation (SO) group. Eight rats from numbered rats of each group were randomly selected to carry out experimental observation. The rats’ body weight, food intake, and fasting blood glucose (FBG) were measured from before operation to postoperative 1–6 months. Meanwhile blood was collected before surgery, as well as at month 1 and 6 after surgery for oral glucose tolerance testing (OGTT) and insulin resistance testing (ITT). Serum glucagon-like peptide (GLP-1), hemoglobin, and albumin levels, as well as vitamin B12, calcium, and ferrum concentrations were measured before surgery as well as at month 1 and 6 after surgery. Results① The body weight, food intake (except 5–6 months), and FBG level in the SADI-S group and SASI group were lower than the SO group (P<0.05) from 1- to6-month after operation, and all obviously decreased at month 1 after operation (P<0.05), but there was no statistical differences between the SADI-S group and SASI group (P>0.05). ② The postoperative OGTT and ITT blood glucose levels in the SADI-S group and SASI group were lower than those in the SO group (P<0.05) and were lower than those in the preoperative levels (P<0.05), and the SADI-S group had a lower OGTT blood glucose level than the SASI group at month 6 after operation (P<0.05). ③ The GLP-1 levels of the SADI-S group and SASI group were higher than that of the SO group (P<0.05), and higher than before operation at month 6 after operation (P<0.05) , but there was no statistical difference was found between the SADI-S group and SASI group after operation (P>0.05). ④ The postoperative albumin levels of the SADI-S group and SASI groups= were lower than of the SO group (P<0.05) and were lower than before operation, and albumin level of the SADI-S group was lower than of the SASI group at postoperative month 6 (P<0.05); while the hemoglobin had no statistical differences among the 3 groups (P>0.05). ⑤ The ferrum concentration of the SADI-S group was lower than that of the SASI group and SO group at 1 month after operation (all P<0.05), while it increased slightly at month 6 after operation and had no statistical difference between the SADI-S group and SASI group (P>0.05); the calcium concentrations of the SADI-S group and SASI group only at 6 month after operation were lower than those of the SO group (P<0.05), and were lower as compared with before operation (P<0.05) , but no statistical difference was found between the SADI-S group and SASI group (P>0.05); the vitamin B12 had no statistical differences among the 3 groups (P>0.05). ConclusionsFor obese rats with type 2 diabetes mellitus, SADI-S and SASI have similar weight loss effect. Long-term glucose reduction of SADI-S shows a advantage than SASI, but influence of postoperative micronutrients of SASI is inferior to SASI.
Objective To discuss the elbow skin fold extension line in Kirschner wire internal fixation of extended supracondylar humeral fractures in children. Methods The clinical data of 58 children with extended supracondylar fractures of the humerus who met the selection criteria between August 2021 and July 2024 were retrospectively analyzed. In 28 cases, needle placement of medial epicondyle of humerus was performed with the assistance of the elbow skin fold extension line (study group), and 30 cases were assisted by routine touch of the medial epicondyle of the humerus (control group). There was no significant difference in baseline data such as gender, age, side, cause of injury, Gartland type, Kirschner wire configuration, and time from injury to operation between the two groups (P>0.05). The closed reduction rate, total operation time, time of medial humeral condyle pin placement, fluoroscopy times during medial pin placement, rate of one-time determination of medial entry point, ulnar nerve injury rate, and fracture healing time were recorded and compared between the two groups. At the same time, the closed reduction rate of patients with the time from injury to operation ≤24 hours and >24 hours was compared. The elbow function was evaluated by Mayo elbow function score. Results The closed reduction rate of the study group was significantly higher than that of the control group (P<0.05). Among all patients, the closed reduction rate of patients with the time from injury to operation ≤24 hours [73.3% (22/30)] was significantly higher than that of patients >24 hours [42.9% (12/28)] (χ2=5.545, P=0.019). The total operation time, medial needle placement time, and fluoroscopy times in the study group were significantly less than those in the control group, and the one-time determination rate of medial needle entry point in the study group was significantly higher than that in the control group (P<0.05). There were 4 cases of ulnar nerve injury in the control group, and no ulnar nerve injury in the study group, but there was no significant difference in the rate of ulnar nerve injury between the two groups (P>0.05). All patients were followed up 6-12 months (mean, 8 months). There was no bone nonunion in both groups, and the fracture healing time of the study group was significantly shorter than that of the control group (P<0.05). Volkmann ischemic contracture, heterotopic ossification, myositis ossificans, and premature epiphyseal closure were not observed after operation. No complications such as loosening or fracture of Kirschner wire occurred. At last follow-up, the Mayo elbow joint function score was used to evaluate function, and there was no significant difference between the two groups (P>0.05). Conclusion In the treatment of extended supracondylar fractures of the humerus in children, the elbow skin fold extension line can help to quickly locate the medial epicondyle of the humerus, quickly insert Kirschner wire, and reduce the operation time and trauma.
Objective To explore the influencing factors for early complications after laparoscopic sleeve gastrectomy (LSG). Methods A retrospective analysis was conducted for the clinical data of 306 obese patients undergoing LSG at the Weight Reduction and Metabolism Center of Xuzhou Medical University Affiliated Hospital of Lianyungang from January 2020 to September 2022. Early postoperative complications (≤30 d) of LSG were classified according to the Clavien-Dindo classification, and the influencing factors of early postoperative complications were explored. Results There were 27 cases (8.8%) suffered from early complications, including 8 cases of grade Ⅰ (2.6%), 15 cases of grade Ⅱ (4.9%), 4 cases of grade Ⅲ (1.3%), there were no grade Ⅳ and grade Ⅴ complications. The multivariate results showed that BMI≥45 kg/m2 [OR=3.63, 95%CI (1.10, 11.92)], high cholesterol [OR=7.12, 95%CI (2.42, 20.95)], and preoperative GERD [OR=3.69, 95%CI (1.11, 12.23)] were influencing factors for early complications. Conclusions LSG is a safe diagnostic and therapeutic method for treating obesity. Attention should be paid to the impact of BMI, high cholesterol, and preoperative GERD on the occurrence of complications after LSG.
ObjectiveTo compare the clinical efficacy of TypeⅡhybrid and Sun’s surgery in treating acute Stanford A aortic dissection. MethodsA retrospective analysis was conducted on the clinical data of patients with acute Stanford A aortic dissection who were treated at the Central Hospital of Wuhan affiliated to Tongji Medical College, Huazhong University of Science and Technology from 2016 to 2022. According to the surgical method, patients were divided into a typeⅡhybrid group and a Sun’s surgery group, and the clinical efficacy of the two groups was compared. ResultsA total of 52 patients were included, with 22 in the typeⅡhybrid group and 30 in the Sun’s surgery group. The typeⅡhybrid group consisted of 18 males and 4 females, with an average age of (58.18±6.00) years, while the Sun’s surgery group consisted of 22 males and 8 females, with an average age of (53.03±11.89) years. All surgeries were successfully completed. There were 4 (13.3%) perioperative deaths in the Sun’s surgery group, including 2 patients of multiple organ failure, 1 patient of paraplegia, and 1 patient of uncontrollable postoperative bleeding. There was 1 (4.5%) perioperative death in the typeⅡ hybrid surgery group, who was suspected of acute coronary syndrome and took a loading dose of dual antiplatelet drugs preoperatively. The patient underwent secondary thoracotomy for hemostasis, was re-cannulated during the operation, and finally died of circulatory failure after implantation of intra-aortic balloon pumping. There was no statistical difference in perioperative mortality between the two groups (P=0.381). Compared with the Sun’s surgery group, the typeⅡhybrid surgery group had shorter cardiopulmonary bypass time [153.00 (135.00, 185.25) min vs. 182.50 (166.50, 196.75) min, P=0.013], aortic cross-clamp time [77.00 (70.50, 92.00) min vs. 102.50 (93.50-109.75) min, P<0.001], postoperative ICU stay [4.0 (2.83, 6.00) days vs. 8.0 (6.38, 11.78) days, P<0.001], postoperative ventilator support time [72.00 (29.50, 93.25) h vs. 87.65 (39.13, 139.13) h, P=0.138], intraoperative blood loss [(1586.82±209.41) mL vs. (1806±292.62) mL, P=0.004], postoperative 24 h drainage volume [612.50 (507.50, 762.50) mL vs. 687.50 (518.75, 993.75) mL, P=0.409], and postoperative hospital stay [18.00 (13.00, 20.25) days vs. 22.00 (17.00, 29.25) days, P=0.013]. There was no statistically significant difference in the incidence of other early postoperative complications such as secondary thoracotomy for hemostasis, tracheotomy, renal dysfunction requiring dialysis, stroke, and paraplegia between the two groups (P>0.05). ConclusionFor patients with acute Stanford A aortic dissection, typeⅡhybrid surgery is safe and effective; compared with traditional Sun’s surgery, typeⅡ hybrid surgery has relatively less trauma, lower incidence of complications, satisfactory short-term results, and further research is needed on long-term prognosis.
ObjectiveTo compare the efficacy of pars plana vitrectomy (PPV) combined with subretinal or intravitreal injection of Conbercept for the treatment of refractory diabetic macular edema (DME). MethodsA retrospective case control study. From June 2022 to March 2024, 32 eyes of 32 patients with refractory DME diagnosed at The Affiliated Eye Hospital of Nanchang University were included in the study. All patients had received regular treatment with anti-vascular endothelial growth factor (VEGF) drugs or corticosteroid drugs for at least 5 times, and had undergone focal retinal laser photocoagulation or panretinal laser photocoagulation, the central macular thickness (CMT) persisted or decreased by less than 50 μm. All affected eyes underwent best-corrected visual acuity (BCVA), intraocular pressure, optical coherence tomography (OCT), microperimetry, and laboratory glycated hemoglobin (HbA1c) testing. BCVA was measured using a standard logarithmic visual acuity chart, and converted to the logarithm of the minimum angle of resolution (logMAR) for statistical analysis. CMT was measured using an OCT device. Microperimetry was performed using an MP-3 microperimeter, recording the mean sensitivity (MS) of the retina within a 12° range of the fovea. The affected eyes were treated with 23G PPV combined with internal limiting membrane peeling and either macular subretinal or intravitreal injection of Conbercept, and were divided into subretinal injection group and the intravitreal injection group, each consisting of 16 cases and 16 eyes. The same equipment and methods as before surgery were used for related examinations at 1, 3, and 6 months post-surgery. Changes in BCVA, CMT, and MS were observed and compared, as well as the number of additional anti-VEGF treatments required within 6 months after surgery. Intergroup comparisons were made using independent samples t tests, and repeated measures data were analyzed using repeated measures analysis of variance. ResultsThe age (t=－0.271), gender composition (χ2=0.001), duration of diabetes (Z=－0.868), HbA1c (t=－0.789), intraocular pressure (t=1.689), logMAR BCVA (t=1.393), CMT (t=－0.613), MS (Z=－0.132), and the number of anti-VEGF injections (t=－0.752) between the subretinal injection group and the intravitreal injection group showed no statistically significant differences (P＞0.05). The within-subject effects comparison of BCVA, CMT, and MS at 1, 3, and 6 months post-surgery compared to pre-surgery for all affected eyes showed statistically significant differences (F=8.060, 125.722, 39.054; P＜0.05). The overall comparison of logMAR BCVA between the subretinal and intravitreal injection groups post-surgery showed no statistically significant difference (F=0.662, P=0.422), however, comparisons of CMT (F=4.540) and MS (F=6.066) showed statistically significant differences (P＜0.05). At 1, 3, and 6 months post-surgery, comparisons of logMAR BCVA between the two groups showed no statistically significant differences (t=－0.123, 0.239, 1.087; P＞0.05), comparisons of CMT showed statistically significant differences (t=－3.474, －4.832, －2.482; P＜0.05), comparisons of MS showed statistically significant differences at 1 and 3 months (t=－2.940, －2.545; P＜0.05), but not at 6 months (t=－1.527, P＞0.05). At 6 months post-surgery, the number of additional intravitreal anti-VEGF injections required in the subretinal and intravitreal injection groups showed a statistically significant difference (Z=－2.033, P=0.042). During the follow-up period and at the final follow-up, no complications such as injection site bleeding, retinal detachment, vitreous hemorrhage, macular hole, or retinal pigment epithelial tear or atrophy occurred in all affected eyes. ConclusionCompared with intravitreal injection, subretinal injection of Conbercept for the treatment of refractory DME has more advantages in reducing macular edema and improving visual function in the macular area, and also reduces the number of postoperative anti-VEGF drug treatments.
