Objective The stentless full root aortic bioprosthesis has superior hemodynamics.Clinical data of Bio-Bentall procedure using stentless full root bioprosthesis of our center was retrospectively analyzed in this perspective for validation.Methods From November 2001 to March 2009,317 adult patients ( 196 male and 121 female) underwent modified Bio-Bentall procedure using the Medtronic Freestyle xenograft as a full root replacement.Two hundred and three patients received an isolated root replacement or a root and ascending aortic replacement (ARR).In 114 patients a variety of concomitant procedures including coronary artery bypass grafting ( n =32 ),mitral valve repair ( n =11 ) and aortic arch replacement ( n =36 ) were performed.(ARR + ).Results Mean patient age was (70.3 ± 10.2) years (range 17 -94 years),97 patients were 75 and older at time of procedure.Mean operative time for the ARR was ( 190 ± 57 ) min with a clamp time of 88 - 27 min.Mean operative time for ARR + group was (282 ±93) min with an average clamp time of (110 ±32) min.Overall operative mortality was 7.9％ (25/317),for ARR it was 5.4％ (11/203 ).Mean ICU stay was (4.9 ± 8.1 ) days,mean hospital stay being (9.8 ± 8.1 ) days.Necessity for bailout bypass surgery among patients with ARR was low at 1.5％ (3/203) comparable to stented xenograft implantations.Echocardiography demonstrated excellent clinical results with low transvalvular gradients especially when a single suture inflow anastomosis technique was used.Conclusion Full root stentless valve implantation preserving porcine root integrity is a valuable option in aortic valve/ascending aorta surgery.Though technically a more challenging operation,it does not lead to increased perioperative morbidity and mortality and can be beneficial mainly for elderly patients with small aortic roots with or without aortic root pathology.

Objective:Characteristics of the retroperitoneal tumor blood supply arteries were analyzed to evaluate the safety and effec-tiveness of preoperative interventional embolization for benign and malignant retroperitoneal tumors. Methods:A total of 241 cases were divided into benign retroperitoneal tumor group and malignant retroperitoneal tumor group. Each group was divided into groups A, B, and C according to the long diameter of the tumor tissue. Group A>10.0 cm, 5.0 cm0.05). Significant differences in intraoperative bleeding and intraoperative blood transfusion were found between groups A and B (P<0.05). Main arteries of the abdominal retroperitoneal tumor are the lumbar, internal iliac, and adrenal arteries. The main artery of pelvic retroperitoneal tumor is the internal iliac artery. Conclusion:Preoperative interventional embolization can effec-tively reduce the risk of bleeding during malignant retroperitoneal tumor surgery and improve the perioperative safety of patients. No significant benefit of benign retroperitoneal tumors and no increased risk of bleeding during surgery were observed. Retroperitoneal tumor preoperative embolization should focus on investigating the lumbar, internal iliac, and adrenal arteries.

Objective To observe the clinical efficacy of yang-warming acupuncture therapy established by Zuo Changbo for the treatment of allergic rhinitis. Methods Sixty patients with allergic rhinitis were randomly divided into observation group and control group, 30 cases in each group. The observation group was given Zuo’s yang-warming acupuncture therapy and the control group was given conventional acupuncture therapy. Acupuncture was performed once every other day, and 10 times constituted one course of treatment. After treatment, the therapeutic effect was evaluated, and the symptom scores of nasal itching, stuffy nose, sneezing and nasal discharge as well as their visual analog scale ( VAS) scores were observed. Results ( 1) Total effective rate of the observation group was 93.3%, and that of the control group was 63.3%, there was significant difference between the two groups ( P<0.01). ( 2) After treatment, the scores of the four symptoms were decreased obviously ( P<0.05 or P<0.01) , and the decrease in the observation group was superior to that in the control group ( P<0.01) . ( 3) After treatment, the VAS scores in both groups were decreased ( P<0.01) , and the decrease was more obvious in the observation group (P<0.01). Conclusion The curative effect of yang-warming acupuncture therapy on allergic rhinitis is better than that of the routine acupuncture group.

ObjectiveTo observe the effect of the Fangfeng Tongshengsan on post-chemoembolization syndrome with primary liver cancer or postoperative liver metastases of colorectal cancer. MethodSeventy-two patients suffered from post-chemoembolization syndrome after transcatheter hepatic arterial chemoembolization were randomly divided into 2 groups， including a Fangfeng Tongshengsan group and a control group， with 36 patients in each group. The patients in Fangfeng Tongshengsan group orally took the decoction for consecutive 7 d. The patients in the control group were physically cooled down with alcohol rub bath and ice pack for consecutive 7 d. Furthermore， the difference of fever， Karnofsky performance status （KPS）， pain in the liver region， nausea vomiting， constipation， and liver function between these two groups were observed. ResultCompared with the control group， Fangfeng Tongshengsan significantly relieved fever， reduced the body temperature （P<0.05）， and shortened the duration of fever （P<0.05）， indicating that Fangfeng Tongshengsan remarkably improved the KPS （P<0.05）. Meanwhile， Fangfeng Tongshengsan obviously alleviated nausea， vomiting， and constipation status and shortened the duration time compared with the control group （P<0.05）. In addition， the parameters of liver function including alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， γ-glutamyl transpeptidase （GGT）， and total bilirubin （TBIL） were significantly decreased in the Fangfeng Tongshengsan group （P<0.05）， which indicated that Fangfeng Tongshengsan alleviated liver dysfunction of patients with post-chemoembolization syndrome. ConclusionFangfeng Tongshengsan can be used to treat post-chemoembolization syndrome with primary liver cancer and postoperative liver metastases of colorectal cancer.
