OBJECTIVE: To study the diagnosis and treatment of parotid Lymphoepithelioma-like carcinoma (LELC), and improve the rate of the diagnosis and treatment. METHOD: Eighteen cases with parotid LELC confirmed pathologically were collected in our department, and the clinical presentation, diagnosis, treatment and prognosis were retrospectively summarized and analyzed from 1982 to 2002. RESULT: All of these LELC patients were found in unilateral side. All cases received Epstein-Barr virus serological test except 2 cases because of refusing, and the testing result displayed: EBV-VCA-IGA positive rate in 93% (15/16); EBV-EA-IGA in 75% (12/ 16); EBV-DNA enzyme in 63% (10/16). Of 16 cases with facial nerve reserved, parotid superficial lobectomy were undertaken in 6 cases, resecting a majority of parotid in 5 cases, whole lobectomy in 5 cases. Facial never resection and whole lobectomy in 2 cases due to facial nerve trunk involved. Functional neck lymph dissection in superior and middle part was undertaken in 14 cases and radical neck lymph dissection in 4 cases, total neck lymph node metastasis rate was 67% (12/18). All of patients received radiotherapy to 50-70 Gy. The follow up were over 1 year, and local recurrence occurred in 2-4 years after operation for 4 cases and had to undergo reoperation. The 1, 3, 5 years survival rates of the 18 cases were 94% (17/18), 72% (13/18) and 50% (9/18), respectively. The chief Causes of death were distant metastasis and local recurrence. CONCLUSION There maybe be close relationship between occurrence of LELC and Epstein-Barr virus infection. Its histopathologic feature is similar to undifferentiated nasopharyngeal carcinoma and nasopharynx biopsy must be demanded before confirming diagnosis for eliminating metastasis focus. The neck lymph node metastasis rate of LELC is high and local invasion is strong. It is important to undergo enlarged local resection, neck lymph dissection and postoperative radiotherapy.

Objective To investigate the effects of in situ venous arterialization on extensive artery obliterans occlusion of the lower extremity. Methods Lumbar sympathetic ganglionectomy and one stage in situ arterialization of the great saphemous vein were performed in 104 ischemic limbs of 88 patients with extensive arterial occlusion. Results Eighty-two of 104 limbs were followed-up from 6 months to over 6 years. The intermittent claudication, night pain improved in all cases, with satisfactory wound healing and no swelling of the lower limbs. Conclusions Arterial blood flow through venous conduit improves and reconstructs the blood circulation of the ischemic limbs.

OBJECTIVETo investigate the effect of atorvastatin on cardiac remodeling and function after acute myocardial infarction (AMI) in rats and whether this effect is mediated by transforming growth factor-β1 (TGF-β1) signaling pathway.

METHODSAMI was induced by left coronary artery ligation in 64 male Sprague-Dawley rats, and 45 surviving rats were randomized into control group (n=15), low-dose atorvastatin group (10 mg/kg, n=15) and high-dose atorvastatin group (20 mg/kg, n=15). Similar surgical procedure was performed in sham-operated rats (n=15) without coronary ligation. Atorvastatin was given daily by gavage from the first day after AMI. Eight weeks later, the cardiac function, left ventricular weight/body mass index (LVMI), collagen volume fraction (CVF), and the expressions of TGF-β1 and Smad2 were compared between the groups.

RESULTSAMI caused significantly reduced cardiac function, increased LVMI and CVF, and upregulated expressions of TGF-β1 and Smad2 mRNA and proteins in the control group (P<0.05). The cardiac function, LVMI, and CVF were improved by atorvastatin, which also down-regulated the expressions of TGF-β1 and Smad2 (P<0.05), and the effects were more prominent in high-dose atorvastatin group (P<0.05).

CONCLUSIONAtorvastatin can dose-dependently improve cardiac remodeling and function after AMI in rats, which is mediated by regulating the activity of TGF-β1/Smad2 signaling pathway.

Pulmonary hypertension is a progressive disease characterized by pulmonary vascular remodeling and eventually develops into right heart failure, which seriously affects the quality of life and safety of patients. Traditional drug therapy can alleviate disease progression, but the prognosis is poor.Mesenchymal stem cells have been shown to be effective in experimental pulmonary hypertension and right heart failure, which is an important research direction in the future.In this paper, the research progress of mesenchymal stem cells in pulmonary hypertension and right heart failure is reviewed.

Objective:To explore the independent risk factors of portal vein thrombosis (PVT) in liver cirrhosis, and to establish and evaluate a risk prediction model for PVT in patients with cirrhosis.Methods:A total of 295 cases of cirrhosis hospitalized in Renmin Hospital of Wuhan University from December 2019 to October 2021 were divided into a modeling set ( n=207) and an internal validation set ( n=88) by the random number table. In addition, patients with cirrhosis hospitalized in Yichang Central People's Hospital, Wuhan Puren Hospital, No.2 People's Hospital of Fuyang City and People's Hospital of China Three Gorges University during the same period were collected as an external validation set ( n=92). The modeling set was divided into PVT group ( n=56) and non-PVT group ( n=151). Univariate analysis was used to preliminarily screen the related indicators of PVT, and then multivariate logistic regression analysis with forward stepwise regression was used to determine independent risk factors for PVT. A nomogram prediction model was constructed based on the independent risk factors obtained. The internal and external validation set were used to verify the predictive ability of the model. Distinction degree was used to evaluate the ability of the model to distinguish patients with or without PVT. Hosmer-Lemeshow goodness-of-fit test was used to evaluate the consistency between predicted risk and the actual risk of the model. Results:Univariate analysis showed that smoking, history of splenectomy, trans-jugular intrahepatic portosystemic shunt (TIPS), gastrointestinal bleeding and endoscopic variceal treatment, and levels of hemoglobin, alanine aminotransferase, aspartate aminotransferase and D-dimer were significantly different between the PVT group and the non-PVT group ( P<0.05). Multivariate logistic regression analysis found that smoking ( P=0.020, OR=31.21, 95% CI: 1.71-569.40), levels of D-dimer ( P=0.003, OR=1.12, 95% CI: 1.04-1.20) and hemoglobin ( P=0.039, OR=0.99, 95% CI: 0.97-1.00), history of TIPS ( P=0.011, OR=18.04, 95% CI: 1.92-169.90) and endoscopic variceal treatment ( P=0.001, OR=3.21, 95% CI: 1.59-6.50) were independent risk factors for PVT in patients with liver cirrhosis. Receiver operator characteristic (ROC) curve analysis showed that the area under the ROC curve (AUC) for the internal validation set was 0.802 (95% CI: 0.709-0.895) ( P<0.001), and the AUC for the external validation set was 0.811 (95% CI: 0.722-0.900) ( P<0.001). Both AUC were larger than 0.75. The calibration curve of Hosmer-Lemeshow goodness-of-fit test showed that the P values of both internal validation set ( χ2=3.602, P=0.891) and the external validation set ( χ2=11.025, P=0.200) were larger than 0.05. Conclusion:Smoking, history of TIPS or endoscopic variceal treatment, levels of D-dimer and hemoglobin are independent risk factors for PVT in patients with liver cirrhosis. The prediction nomogram model based on the above factors has strong predictive ability.
