OBJECTIVETo introduce the experience in coronary artery bypass grafting (CABG) combined with concomitant valve operation.

METHODSFrom 1998 to 2002, forty-five patients (38 men and 7 women) with coronary artery lesion and valve diseases underwent myocardial revascularization combined with concomitant valve operation. The mean age of the patients was 59 years (42 to 75 years). Heart function was Class II (NYHA) in 7 patients, Class III in 30, Class IV in 8. The value of ejection fraction was 0.32 to 0.50. Thirty patients had mitral valve lesion, 7 aortic lesion, and 8 both lesions. Seventeen patients had single-vessel diseases, 20 double-vessel diseases, 8 triple -vessel diseases, and 8 left main artery lesion. After cardiac arrest by cold blood cardioplegia under moderate cardiopulmonary bypass (CPB), distal anastomosis of the saphenous vein (SV) to the target vessels were firstly performed and followed by valve replacement (32 patients) or plasty (2). The left internal mammary artery (LIMA) was grafted to the left anterior descending artery (LAD) before aortic unclamping. Proximal anastomosis of the SV to the aorta was finally finished on beating heart. The mean bypass time was 173.5 min and the mean duration of aortic cross-clamping time was 112.6 min.

RESULTSNo mortality occurred during hospitalization and all patients were discharged 9.2 days after operation. Cardiac function of all patients was improved to Class I-II and no patient died during follow-up.

CONCLUSIONSCABG combined with valve surgery can be safely performed with good results.

OBJECTIVETo investigate the serologic type, phage-biotype and toxic factor of Vibrio cholerae isolated from different sea products, analyze the relation between the Vibrio cholerae in sea products and cholera epidemiology, and provide references for forecasting cholera epidemic situation and drawing out a preventing plan.

METHODThe biotype of strains isolated was analyzed by using type and phage-biotype serological methods. The toxic gene was detected by PCR.

RESULTSThe constituent ratio of V. cholerae O139, Ogawa and Inaba were, respectively, 48.44%, 20.31% and 31.25% in 64 strains of V. cholerae. The result of phage-biotype showed that the 26 strains of V. cholerae O1 were all non-epidemic strains. The result of toxic gene detecting showed that positive rate of V. cholerae O139 was higher than those of Ogawa and Inaba.

CONCLUSIONThe positive rate of toxic gene in V. cholerae O139 was high and the V. cholerae O139 was mainly in turtle, breed aquatics water and crustacean, so these sea products were the important sectors in cholera prevention and control.

Objective To better understand the epidemiology of rabies during the past ten years in Yancheng city,Jiangsu province. Methods Data was collected and analyzed on rabies cases in Yancheng. Density and vaccination rate on Canine,Rate of injured people bit by dogs,and the information of post-exposure prophylaxis were studied. Rabies virus in the dog brains,collected around the epidemic areas of Yancheng,were detected and analyzed. Results A total of 135 human rabies cases occurred from 1999 through 2008,and formed the second epidemic peak since 1958. Of these victims,84% (114) were farmers. In general,the rate of people having dogs were 3%-6% per 100 people,and the injured person-times of 100 dogs were 6.37 per year. Notably,the vaccination rate of dogs was only 20%. Of those people injured by dogs and other animals,77% had received post-exposure treatment,and only 5%-10% had been administered anti-rabies serum. Rabies virus antigen was found in 4 (3.6%) of 111 brain specimens among dogs collected from epidemic areas. Genetic analysis of N and G genes,which were amplified from brain specimens,indicated that these viruses belong to genotype Ⅰ rabies and expressing a close relationship with the Chinese vaccine strain CTN. Conclusion The large number of dogs with low vaccination rate among them,together with the incorrect and low post-exposure treatment in rural areas seemed to be responsible for the outbreak of rabies in Yancheng city.

BACKGROUNDBacterial lipopolysaccharide (LPS) can activate immunological cells to secrete various proinflammatory cytokines involved in the pathophysiological process of disseminated intravascular coagulation (DIC) during infection. In recent years, it has been found that bone marrow-derived mesenchymal stem cells (BMSCs) can affect the activity of these immune cells and regulate the secretion of proinflammatory cytokines. Here, we report the possible protective effect of BMSCs pre-treatment in LPS-induced DIC rat model and the mechanism.

METHODSForty-eight adult male rats were divided into five experimental groups and one control group with eight animals in each group. In the treatment groups, 0, 1'10(6), 2'10(6), 3'10(6), and 5'10(6) of BMSCs were injected intravenously for 3 days before LPS injection, while the control group was treated with pure cell culture medium injection. Then, the LPS (3 mg/kg) was injected via the tail vein in the treatment groups, while the control group received 0.9% NaCl. Blood was withdrawn before and 4 and 8 hours after LPS administration. The following parameters were monitored: platelets (PLT), fibrinogen (Fib), D-dimer (D-D), activated partial thromboplastin time (APTT), prothrombin time (PT), tumor necrosis factor-a (TNF-a), interferon-g (IFN-g), interleukin-1b (IL-1b), creatinine (Cr), alanine aminotransferase (ALT), creatinine kinase-MB (CK-MB), and endothelin (ET).

RESULTSCompared with the control group, a significant change of coagulation parameters were found in the experimental groups. The plasma level of the inflammatory mediator (TNF-a, IFN-g, IL-1b), organ indicator (Cr, ALT, and CK-MB), and ET in the experimental groups were much lower (P < 0.05) than that in the control group. Furthermore, some of these effects were dose-dependent; the statistical comparison of the plasma levels between the groups (from group 2 to group 5) showed a significant difference (P < 0.05), except the ALT and CK-MB levels (P > 0.05).

CONCLUSIONPre-treatment with BMSCs can attenuate organ dysfunction and inhibit systemic intravascular coagulation effectively via the regulatory effect on immune cells and proinflammatory cytokines in LPS-induced DIC rat model.

OBJECTIVETo summarize the experience in performing left ventricular aneurysmectomy (LVA) with geometric reconstruction and concomitant coronary artery bypass grafting (CABG) without mortality.

METHODSForty-two patients underwent LVA with geometric reconstruction and concomitant CABG. Forty-one patients were male, one was female with mean age of (55.5 +/- 2.4) years (40 - 68 years). Preoperative cardiac function was NYHA class III in 32 patients and class IV in 10. Thirty-eight patients had unstable angina pectoris and 10 had the history of severe ventricular arrythmia. Eight patients had ventricular tachycardia. Preoperative left ventricular ejection fraction (LVEF) was 41% (17% - 63%), LVEF was less than 40% in 29 cases. Left ventricular anatomic aneurysms were confirmed by ventriculography. Thirty-three cases underwent Jatene technique; 8 cases, Dor technique, and 1 case, Cooley technique. Mural thrombi were found in 21 patients and were completely removed. CABG was concomitantly performed in all patients. All of the left anterior descending artery was bypassed with left internal mammary artery and the other target vessels with saphenous vein. Mean cardiopulmonary bypass time was (135 +/- 11) minutes and aortic clamping time was (78 +/- 10) minutes.

RESULTSNo hospital mortality occurred and all patients were discharged. Postoperative reexploration for bleeding in 1 patient. The diameter and end systolic and diastolic volume of left ventricle were significantly decreased to nearly normal after operation. Operative ejection fraction had a tendency to increase but without significance (P > 0.05).

CONCLUSIONSLVA with geometric reconstruction and concomitant CABG could not only improve heart function but also eliminate ventricular arrythmia. The clinical result was excellent.

Objective:To explore the feasibility and application value of indocyanine green(ICG)lymph node tracer in clinical early stage cervical cancer staging surgery.Methods:A retrospective analysis was performed on 31 patients with early clinical stage(ⅠA1-ⅡA1)cervical cancer who underwent laparoscopic radical hysterectomy,pelvic lymph node resection and para-aortic lymph node sampling were selected as the study subjects in Sichuan Provincial Maternal and Child Health Care Hospital from April 1,2022 to July 31,2023.They were divided into the ICG fluorescence tracer group(ICG group,17 cases)and the conventional surgery group(control group,14 ca-ses)based on whether ICG was injected or not.The resected lymph nodes were classified and submitted for ex-amination according to location and whether they presented visualization.The method of contingency coefficient was used to analyze the correlations between lymph node visualization patterns and lymph node metastasis and clinicopathological characteristics,and the perioperative data of the two groups were compared.Results:①The postoperative stage of 8 patients(25.8％)(4 in each group)were improved compared with the preoperative clini-cal stage.The number of resected lymph nodes in the ICG group was less than that in the control group(18±9 nodes/person vs.26±11 nodes/person,P＜0.05).There were no statistically significant differences in operation time,intraoperative blood loss,postoperative FIGO(2018)staging,lymph node metastasis rate,and positive rate of resected lymph nodes between the two groups(P＞0.05).②The visualization rate in the ICG group was 64.71％(11/17).There was no statistically significant difference in the positive rate between the visualized and non-visualized lymph nodes(P＞0.05).There was a significant correlation between lymph node visualization and lymph node metastasis(C=0.707,P＜0.05),and a significant correlation was found between lymph node visual-ization and lymph node metastasis in the same patient(C=0.557,P＜0.05).Conclusions:The rate of lymph node metastasis in clinical early stage cervical cancer is low.ICG fluorescence visualization can trace lymph nodes and predict the risk of metastasis.By only resecting the visualized lymph nodes under the guidance of ICG tracer,the lymph node metastasis status of early-stage cervical cancer can be fully evaluated,which is worthy of further research.
