Objective:To investigate the incidence and risk factors of renal injury in human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS) patients with poor immune reconstitution.Methods:The HIV infection/AIDS patients with poor immune reconstitution who were visited Second Department of Infection of Hangzhou Xixi Hospital from January to December 2021 were enrolled. The clinical data and laboratory examinations of the patients were collected, and the relevant risk factors were analyzed by logistic regression.Results:Among 303 HIV infection/AIDS patients with poor immune reconstitution, 59(19.5%) patients had renal injury. Logistic regression analysis showed that hypertension (odds ratio ( OR)=0.200, 95% confidence interval (95% CI) 0.065 to 0.618, P=0.005), taking tenofovir ( OR=0.275, 95% CI 0.130 to 0.580, P=0.001), hypoproteinemia ( OR=1.045, 95% CI 1.006 to 1.086, P=0.022), and low CD4 + T lymphocytes level ( OR=1.009, 95% CI 1.003 to 1.014, P=0.001) were risk factors for renal injury. Conclusions:The incidence of renal injury in HIV infection/AIDS patients with poor immune reconstitution is high. Hypertension, taking tenofovir, hypoproteinemia, and low CD4 + T lymphocytes level are risk factors for renal injury in patients.

Objective    To introduce a modified sutureless technique and its surgical results in the treatment of total anomalous pulmonary venous connection (TAPVC). Methods    Clinical data of 11 patients with TAPVC who underwent the modified sutureless technique treatment from 2014 to 2019 in our center were retrospectively analyzed, including 4 males and 7 females. The median surgical age was 1.4 (0.3, 27.0) months. The median weight was 4.3 (3.5, 8.5) kg. Six (54.5%) patients were of supracardiac subtype, and five (45.5%) patients were of infracardiac subtype. Five (45.5%) patients had preoperative severe pulmonary hypertension, and three (27.3%) patients had preoperative pulmonary vein obstruction. The surgical results were compared with those of 10 patients treated with conventional surgical technique. Results    The median follow-up was 12 (range, 1-65) months. During the follow-up, no death or postoperative pulmonary vein obstruction occurred in the modified sutureless technique group. The perioperative data and relief of re-obstruction were superior in the modified sutureless technique group, but the difference was not statistically significant (P>0.05). The postoperative survival of the the modified sutureless technique group was better than that of the traditional surgery group (P=0.049). Conclusion    The modified sutureless technique which includes partial suture and then incising, and eversion of pulmonary vein incision, is a safe and reliable method for the treatment of TAPVC with satisfactory short-term results.

We reported a case of a six-year-old boy diagnosed of single ventricle, pulmonary atresia and interrupted inferior vena cava. After modified Blalock-Taussig shunt and bidirectional Glenn procedure, he received the Fontan procedure. The Fontan procedure was done through a unilateral thoracotomy, using an autologous pericardial conduit to connect hepatic vein and azygos vein. The result of short-term follow-up was satisfactory.

Objective To evaluate the value of real-time three-dimensional transesophageal echocardiography (TEE) in the diagnosis of mitral valve structure in mitral valve prolapse, the significance of determining the prosthetic mitral valve ring size in the surgical treatment and the evaluation of immediate postoperative effect. Methods From November 2016 to March 2017, 19 patients with mitral prolapse performed with surgical treatment were diagnosed by transthoracic echocardiography at the echocardiography and vascular ultrasound center in the First Affiliated Hospital of Zhejiang University. All 19 patients underwent real-time three-dimensional TEE examination after anesthesia and before cardiopulmonary bypass. When the heart was recovered immediately after the operation, TEE was performed again to check the valve and the images were recorded in real time. During the whole examination, the images were observed by sonologists, surgeons and anesthesiologists, and the sonographic results were compared with the intraoperative findings. Totally 19 patients with moderate to severe mitral valve prolapse were examined and measured with real time three-dimensional ultrasound reconstruction. The mitral valve and tendons were observed and the mitral valve ring, the length of the valve and the diameter of the fiber triangle were measured. Results Intraoperative TEE examination could clearly display the anatomical structure and movement of mitral valve, annulus, chordae tendineae and papillary muscles from any angle. Real time observation of mitral valve thickness, mobility, calcification, vegetations and chordae tendineae rupture was effective. It was able to diagnose the thrombosis and patent foramen ovale. In the 19 patients, the TEE diagnosis of mitral valve prolapse was almost consistent with operative findings, and P2 was the most common area. The etiology was detected in 15 cases caused by rupture of mitral chordae tendineae, which was consistent with operative findings, and the accuracy rate was 100%. The size of the prosthetic ring provided by TEE in 14 cases was consistent with operative findings among 19 patients. The accuracy rate was 73.7% (4/9). Four cases were selected 1 size down than TEE, and 1 case was selected 1 size up than TEE. Conclusions The application of real-time three-dimensional ultrasound reconstruction can objectively reflect the pathogeny and pathological changes of prolapse, and provide a visual stereoscopic image, which is of great reference value for the formulation of the operation scheme. It also provides a basis for selecting the size of the forming ring and saves the operative time. It has practical clinical guiding significance. The function of the autologous valve is evaluated immediately after the operation, and the ventricular wall movement and left ventricular systolic function are detected in real time, and the left heart gas could be monitored. It is helpful to the intraoperative monitoring of the anesthesiologist and increase the success rate of the operation.

Objective To study the anatomy of the caudate lobe and to apply the knowledge in caudate lobe resection and piggyback liver transplantation. Methods Dissection of the caudate lobe was carried out in 35 fresh adult livers. Before dissection, the portal venous system was injected with barium sulfate emulsion to show the portal branches of the caudate lobe. Results The caudate lobe was shown to consiste of 3 portions: (1) the Spigelian lobe, the paracaval portion and the caudate process. The Spigelian lobe was pyramidal in shape with 3 faces, a peak and a base; (2) the paracaval portion was situated to the right and to the front of the vena cava; (3) the caudal process was the liver parenchyma between the hepatic hilum and the anterior aspect of the vena cava. Conclusions The entire caudate lobe is situated at the posterior part of the liver and it surrounds the vena cava. The key point in resecting the entire caudate lobe or in performing a piggyback liver transplantation is adequate mobilization and division of all the outflowing veins of the caudate lobe.

Objective To observe therapeutical effects of gastric bypass on non-obese type 2 diabetes patients.Methods From June 2008 to April 2010,data of 47 patients with both gastric lesions and non-obese type 2 diabetes mellitus undergoing gastric bypass in the Institute of General Surgery were studied.The patients were divided into 3 groups according to the operation type:total stomach resection plus Roux-en-Y anastomosis ( n =20),partial stomach resection plus Roux-en-Y anastomosis(n =13)and Billroth Ⅱ gastrectomy(n =14).They were followed for 6 months after surgery.Level of body mass index (BMI),fasting blood glucose (FBG) and GLP-1 was measured before operation and on the 1 st week,2nd week,1 st month,3rd month,and 6th month after operation.The level of glycosylated hemoglobin was measured before operation and on the 3rd and 6th month after operation.The prognosis of the patients on the 6th month after surgery was evaluated.Results Compared with preoperative level,FBG level in all the 3 groups significantly decreased on the 1 st week after surgery and maintained a similar level during the follow-up period (P ＜ 0.01 ).GLP-1 level was elevated after operation (P ＜0.01 or P ＜ 0.05).On the 3rd and 6th month after operation,glycosylated hemoglobin level in all the 3 groups significantly decreased (P ＜ 0.01 or P ＜ 0.05 ).The change of the above parameters was greater in groups undergoing Roux-en-Y anastomosis than in Billroth Ⅱ group(P ＜ 0.05 ).The control rate of T2DM for Billroth Ⅱ,partial stomach resection plus Roux-en-Y anastomosis and total stomach resection plus Roux-en-Y anastomosis was 78.5％(11/14),100％ (13/13) and 100％ (20/20)respectively on the 6th month after surgery,indicating Roux-en-Y gastric bypass had better effect of blood glucose control than Billroth Ⅱ (P ＜ 0.05 ).Postoperative BMI decreased significantly in all groups (P ＜ 0.05) and there was no statistical difference between all the groups (P ＞ 0.05 ).Conclusions All groups of gastric bypass are effective in terms of glucose control.Roux-en-Y gastric bypass is more effective than Billroth Ⅱ on diabetes control and its therapeutic effect is independent of weight loss.
