Objective To evaluate the expressions and roles of survivin (SVV), bcl-2 and proliferating cell nuclear antigen(PCNA) in cutaneous squamous cell carcinoma (SCC). Methods The expressions of SVV, bcl-2 and PCNA were investigated by SP immunohistochemistry technique in 82 cases of SCC and 18 normal skin samples. Results There were 79.3% of SCC patients with the expression of SVV (P

Objective To explore the expression and clinical significance of survivin protein and proliferation cell nuclear antigen(PCNA) in human nasopharyngeal carcinoma (NPC). Methods The expression of survivin protein and PCNA was detected by SP immunohistochemical technique in 96 cases of NPC tissues. Results The positive rate of survivin expression was 75.0% in PNC. Labeling idex(LI) of PCNA in survine positive NPC was higher than that in survivin negative NPC. The positive rate of survivin expression in NPC with neck lymph node metastasis was higher than that in NPC without neck lymph node metastasis. The positive rate of survivin expression in NPC patients with less than 5-year survival rate was higher than that in NPC patients with over 5-year survival rate. Conclusion NPC had survivin expression, and survivin expression in NPC was positive related with PCNA expression. The survivin protein might promote the neck lymph node metastasis of NPC cells. The prognosis of the patients with survivin positive NPC was worse.

Objective To investigate the expression and clinical significance of survivin and proliferating cell nuclear antigen(PCNA) in human esophageal carcinoma. [WTHZ]Methods The expression of survivin and PCNA was detected by immunohistochemical SP method in 98 cases of esophageal carcinoma and paired normal mucosa adjancent to tumor. Results The positive rate of survivin expression in esophageal carcinoma and normal mucosa adjancent to tumor was 80.6% and 7.1%, respectively, which was obviously higher in the former than in the latter(P

Objective The results of Aortic valve replacement (AVR). Combined with ascending aortic replacement(group A) or aortoplasty (group B) in patients with aortic valve disease and ascending aortic dilatation were analysed to assess the clinical outcomes and respective indications. Methods Among the two groups, the age, gender, NYHA class, types of aortic valve lesions and left ventricular ejection fraction were not different statically. The ascending aortic diameters in group A[(50.41 ±3.71) mm] and group B [(48.29±2.18) mm] were not statically different. Ascending aortic replacement was performed in Group A. A Dacron tube(diameter 28 ～ 30mm) was routinely wrapped around the ascending aorta after aortoplasty in group B. Results There was 1 postoperative death in group B, blood transfusion volume and postoperative complications were not stasticaly different in the two groups. Cardiopulmonary bypass time [(110.52 ± 27.51) min] and aortic across clumping time [(71.70 ± 17.13)min] in group A were significantly longer than that of group B [(97.31 ± 19.46) min,P=0. 004; (57.13 ±19.46) min, respectively. P=0.025]. Conclusion Aortic valve disease, especially bicuspid valve disease often combines with ascending aortic dilatation or aneurysm. In younger patients, ascending aorta should be actively treated surgically when the diameter is equal or more than 40mm. Aortoplasty with external reinforcement of a Dacron tube is simpler and safer than aortic replacement in patient without aortic atherosclerosis or ulceration, and large aneurysm.

Objective To summary the methods and results of first and second operations on patients with aortic valve disease and non-specific aortitis.Methods The total 34 patients including 23 cases with aortitis and 11 cases with Behcet disease were studied from Jan 2000 to Dec 2010.The first operation was Bentall procedure in 18 cases and AVR in 16 cases.Fourteen of 16 cases who had AVR developed severe paravalvular leakage,and undewent the second operation including 10 aortic root replacement (8 valve-conduit and 2 homograft) and 4 non-anatomic AVR.Results Eighteen patients who had first operation of Bentall procedure all survive without aortic pseudoaneurysm after the follow-up of 6 months to 11 years.Fourteen redo cases all survive except for one case died of repture of aortic pseudoaneurysm 1.2 years postoperatively.Conclusion Preoperative diagnosis in these patients is very difficulty.The first operation of root replacement is of choice.The second operation is very difficulty to handle,root replacement can achieve satisfactory results.Non-anatomic AVR is easy to perform,and good hemo stasis intraoperatively,and is a satisfied alternative method with good results.

Objective To discuss of the therapeutic effects of treating three TCM types of Chronic superficial gastritis (CSG)disharmony of liver and stomach, weakness of the spleen and the stomach, and damp heat in the spleen and the stomach with chinese medicine, and to discuss its impact on the changes of three gastrointestinal hormones-- motilin (MTL), gastrin (GAS), and somatostatin (SS). Methods The data of 150 CSG patients in Shenzhen Bao’an Hospital from Feb, 2011 to Mar, 2013 were selected. These patients belonged to three kinds of syndrome, which was disharmony of liver and stomach, weakness of the spleen and the stomach, and damp heat in the spleen and the stomach, each syndrome had 50 cases. Different Chinese medicines were applied to different syndrome of patients. After one month treatment, the therapeutic effects and the changes of MTL, GAS, SS in these patients were detected by radioimmunoassay. Results After treatment, the total effective rate of the damp heat in the spleen and the stomach syndrome was 94%, the weakness of the spleen and the stomach type was 88%, disharmony of liver and stomach type was 90%, the difference was not statistically significant among the three types(χ2=3.84, P>0.05);after treatment, the serum MTL, SS level of disharmony of liver and stomach, weakness of the spleen and the stomach, and damp heat in the spleen and the stomach type were [damp heat in the spleen and the stomach type were (240.25±7.29)pg/ml, (68.23± 5.97)pg/ml;the weakness of the spleen and the stomach type were (260.16±8.84)pg/ml, (75.35±4.65)pg/ml;disharmony of liver and stomach type were(258.32±15.23)pg/ml, (80.12±7.88)pg/ml] higher than before treatment [damp heat in the spleen and the stomach type were (87.26±7.58)pg/ml, (49.34±4.93)pg/ml;the weakness of the spleen and the stomach type were (67.11±7.81)pg/ml, (57.15±5.11)pg/ml; disharmony of liver and stomach type were (89.26±7.60)pg/ml, (40.63±7.26)pg/ml], and the levels of serum GAS [(156.38±17.36)pg/ml, (146.15±15.56)pg/ml, (140.26±13.37)pg/ml] was lower than before treatment [(274.59 ± 17.82)pg/ml, (320.83 ± 15.02)pg/ml, (216.15 ± 13.77)pg/ml], the difference was statistically significant (P<0.05 or 0.01). Conclusions The changes of three hormones-MTL, GAS, SS can be used as an objective basis for the diagnosis and the judgment of healing efficacy of CSG treated by traditional Chinese medicine.

Objective To evaluate the methods and consequences of surgical technique in the treatment of Stanford A aortic dissection.Methods 108 patients with type Standford A aortic dissection underwent surgery in our study,including urgent surgery in 53 and selective surgery in 55.The operation was performed under deep hypothennic circulatory arrest (DHCA) in 85 cases.Surgical procedures included ascending and semi arch replacement or total arch replacement (some cases combined with stented graft implanted into the descending aorta),"elephant trunk" procedure.Concomitant procedures included repair of intimal tear in arch or descending aorta,Bentall procedure,aortic valve replacement,Cabrol or modified Cabrol procedure,aortic valvuloplasty,mitral valvuloplasty or mitral valve replacement,tricuspid valvuloplasty and CABG.Results In-hospital mortality was 6.5% (7 of 108 patients).The mor- tality was 7.5% (4 of 53 patients) in urgent surgery group and in elective surgery group was 5.4% (3 of 55 patients).Ninety six percent survived patients were followed up for 1 month to 13.3 years [mean (3.2?1.3) years] and 2 deaths occurred during the fel- low-up period.3 patients underwent re-operatian.Conclusion The choice of surgical procedures depend on the location of intimal tear for Stanford A aortic dissection.The better operative effects can be expected with proper surgical indication,perfecting surgical technique,and enhancing postoperative treatment.
