ABSTRACT
Objective: To investigate the factors influencing small intestinal ischemia in elderly patients with incarcerated hernia. Methods: The clinical data of 105 elderly patients admitted for surgical procedures of incarcerated hernia at Department of General Surgery, Huadong Hospital between January 2014 and December 2021 were retrospectively analyzed. There were 60 males and 45 females, aged (86.1±4.3) years (range: 80 to 96 years). They were divided into normal group (n=55) and ischemic group (n=50) according to intraoperative intestinal canal condition. The t test, χ2 test and Fisher's exact probability method were used for the univariate analysis of the factors that influence intestinal ischemia in patients, and Logistic regression was used for multifactorial analysis. Results: In all patients, 18 patients (17.1%) had irreversible intestinal ischemia with bowel resection. Six patients died within 30 days, 3 cases from severe abdominal infection, 2 cases from postoperative exacerbation of underlying cardiac disease, and 1 case from respiratory failure due to severe pulmonary infection. The results of the univariate analysis showed that there were differences in gender, history of intussusception, duration of previous hernia, white blood cell count, neutrophil percentage, C-reactive protein, type of incarcerated hernia, and preoperative intestinal obstruction between the two groups (all P<0.05). The Logistic regression results showed that the short time to the previous hernia (OR=0.892, 95%CI 0.872 to 0.962, P=0.003), high C-reactive protein (OR=1.022, 95%CI 1.007 to 1.037, P=0.003), non-indirect incarcerated hernia (OR=10.571, 95%CI 3.711 to 30.114, P<0.01) and preoperative intestinal obstruction (OR=6.438, 95%CI 1.762 to 23.522, P=0.005) were independent risk factors for the development of intestinal ischemia in elderly patients with incarcerated hernia. Conclusions: The short duration of the previous hernia, the high values of C-reactive proteins, the non-indirect incarcerated hernia, and the preoperative bowel obstruction are influencing factors for bowel ischemia in elderly patients with incarcerated hernia. A timely operation is necessary to reduce the incidence of intestinal necrosis and improve the prognosis.

OBJECTIVE: To analyze the application value of biological mesh in inguinal hernia patients aged from 18 to44 years old. METHODS: The clinical data of 127 patients with inguinal hernia admitted from January 2013 to December 2018 in Huadong Hospital Affiliated to Fudan University were analyzed retrospectively. Through the abdominal transverse fascia reinforcement with biological mesh(tTRB), it was to observe indicators during perioperative and followup periods, to explore the application value and treatment experience of biological mesh in young patients with inguinal hernia. RESULTS: All the 127 cases were successfully completed. There were obvious pain in 3 cases and scrotal edema in 3 cases. No other patients were found to have obvious discomfort. All patients had no complications such as recurrence, chronic pain and infection after 3 to 12 months of follow-up. CONCLUSION: The rational use of biological mesh to repair young and middle-aged patients with inguinal hernia is effective. The advantage is that the effect of mesh minimize the impact on long-term quality of life in young patients. At the same time, the risk of postoperative infection and chronic pain is effectively reduced by reinforcement of transverse fascia with biological mesh, which is worthy of further study.
ABSTRACT
<p><b>OBJECTIVE</b>To study the effects of allicin on cardiac function and underlying mechanism in rat model of myocardial infarction (MI).</p><p><b>METHODS</b>Ninety-four Wistar rats were randomly assigned to 6 groups (n=14-16 per group): sham control group [underwent thoracotomy without left anterior descending (LAD) occlusion and only received an injection of the same amount of citrate buffer], MI control group (subjected to LAD occlusion and only received an injection of same amount of citrate buffer), positive control group (subjected to LAD occlusion and received an injection of diltiazem hydrochloride at the dose of 1.5 mg/kg), and MI + allicin groups (subjected to LAD occlusion and received an injection of allicin at the doses of 1.2, 1.8, and 3.6 mg/kg). All of the drugs were administered intraperitoneally daily for 21 days. The infarct area was measured by myocardial staining. Hematoxylin-eosin staining was used to observe the pathological changes. Cardiac function parameters were assessed by echocardiography. The myocardial apoptotic index was estimated by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling staining. The expression of Bax and Bcl-2 were detected by quantificational real-time polymerase chain reaction and Western blot.</p><p><b>RESULTS</b>Treatment with allicin could attenuate the myocardial infarct area (P<0.05) and relieve the changes of the myocardium. The left ventricular anterior wall diastolic and systolic thicknesses were increased in the allicin-treated groups (P<0.05), while there was no signifificant difference in the left ventricular posterior wall diastolic and systolic thickness (P>0.05). The left ventricular internal diameter in systole, ejection fraction, fractional shortening, and stroke volume were dramatically elevated in allicin-treated rats (P<0.05). Allicin dose-dependently reduced creatine kinase and lactate dehydrogenase levels (P<0.05). The myocardial apoptotic index was also markedly lowered, and Bax expression was signifificantly decreased, whereas Bcl-2 expression exhibited an opposite trend in allicin-treated rats (P<0.05).</p><p><b>CONCLUSION</b>Allicin appears to exert a cardioprotective effect that may be linked to blocking Bcl-2/Bax signaling pathway-denpendent apoptosis, further improving cardiac function.</p>
ABSTRACT
Allicin is the internationally accepted active substance of garlic, and has cardiovascular protective effect. This research was designed to investigate the effect of allicin on myocardial fibrosis after myocardial infarction and explore the relationship between the effect and TGFβ1/Smads signaling pathway. The rat myocardial infarction model were made by ligating the left anterior desending coronary artery. The drugs were administered intraperitoneally 24 h after the operation. After 21 days, the rats were sacrificed and myocardial collagen fibres were observed by Masson staining. The protein expression of Ⅰ, Ⅲ collagen and TGFβ1, Smad3, Smad7 in the myocardium was measured by the immunohistochemistry. The results showed that myocardial fibrosis was serious and the expression of Ⅰ, Ⅲ collagen was increased in model group. After treatment with allicin, the myocardial fibrosis could be relieved markedly, and the expression of collagen was down-regulated. Meanwhile, TGFβ1 and Smad3 in heart tissue could be down-regulated and Smad7 could be up-regulated in allicin groups. So allicin may exhibit anti-myocardial fibrosis effect on rats, and the mechanism of this is related to TGFβ/Smads signal transduction.
