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 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 observe the clinical effect of subretinal injection and intravitreal injection of conbercept in the treatment of polypoid choroidal vasculopathy (PCV). MethodsA prospective, randomized double-blind controlled study. From June 2022 to January 2023, 35 patients of 35 eyes with PCV diagnosed at Affiliated Eye Hospital of Nanchang University were included in the study. All patients were first-time recipients of treatment. Best corrected visual acuity (BCVA), optical coherence tomography (OCT), and indocyanine green angiography (ICGA) were performed in all affected eyes. BCVA was performed using an international standard visual acuity chart and converted to logarithmic minimum resolved angle (logMAR) visual acuity for statistical purposes. Enhanced depth imaging with OCT instrument was used to measure the macular retinal thickness (MRT), subfoveal choroidal thickness (SFCT), and pigment epithelium detachment (PED) height. Randomized numerical table method was used to divide the patients into subretinal injection group (group A) and vitreous cavity injection group (Group B), 18 cases with 18 eyes and 17 cases with 17 eyes, respectively. Comparison of age (t=0.090), disease duration (t=−0.370), logMAR BCVA (t=−0.190), MRT (t=0.860), SFCT (t=0.247), and PED height (t=−0.520) between the two groups showed no statistically significant difference (P＞0.05). The eyes of group A were given one subretinal injection of 10 mg/ml conbercept 0.05 ml (containing conbercept 0.5 mg), and subsequently administered on demand (PRN); eyes in group B were given intravitreal injection of 10 mg/ml conbercept 0.05 ml (containing conbercept 0.5 mg). The treatment regimen was 3+PRN. Lesions were categorized into active and quiescent according to the results of post-treatment OCT and BCVA. Active lesions were treated with intravitreal injection of conbercept at the same dose as before; stationary lesions were followed up for observation. BCVA and OCT were performed at 1, 2, 3, 6 and 9 months after treatment; ICGA was performed at 3, 6 and 9 months. BCVA, MRT, SFCT, and PED height changes before and after treatment were compared and observed in the affected eyes of the two groups. Independent sample t-test was used to compare between the two groups. ResultsWith the prolongation of time after treatment, the BCVA of the affected eyes in groups A and B gradually increased, and the MRT, SFCT, and PED height gradually decreased. Compared with group B, at 2, 3, 6, and 9 months after treatment, the BCVA of group A was significantly improved, and the difference was statistically significant (t=−2.215, −2.820, −2.559, −4.051; P＜0.05); at 1, 2, 3, 6, and 9 months after treatment, the MRT of the affected eyes in group A (t=−2.439, −3.091, −3.099, −3.665, −5.494), SFCT (t=−3.370, −3.058, −3.268, −4.220, −4.121), and PED height (t=−3.460, −4.678, −4.956, −5.368, −6.396) were significantly reduced, and the differences were statistically significant (P＜0.05). No complications such as intraocular inflammation, high intraocular pressure, or vitreous hemorrhage occurred in any of the affected eyes during or after treatment. ConclusionCompared with the intravitreal injection of conbercept, the subretinal injection of conbercept can more effectively reduce the height of MRT, SFCT, PED height, and improve the visual acuity of the affected eyes with PCV.
