Objective To investigate the expression of succinate dehydrogenase subunit A(SDHA)and subunit B (SDHB) in patients with renal cell carcinoma (RCC),and its relationship with the clinicopathologic characteristics. Methods The expression of SDHA and SDHB was detected in 179 cases of RCC by immunohisto-chemistry and the relationship between the SDHA ,SDHB expression and the clinicopathologic characteristics of RCC were analyzed. Results In 179 cases of RCC,18 cases(10.1%)were shown with negative or suspicious-negative expression of SDHA and SDHB,including 2 cases(1.1%)with suspicious-negative expression of SDHA and SDHB. 12 cases(66.7%)had tumor located in left kidney and 6 cases(33.3%)had tumor located in right kidney. The well-differentiation group contained 15 cases(83.3%),moderate-differentiation group contained 1 case (5.6%)and poor-differentiation group contained 2 cases(11.1%). Most of SDH negative and suspicious negative RCC had the following characteristics that the normal renal tubule could be seen within the tumor. The tumor was composed of polygonal cells arranged in nest ,and the polygonal cells were separated by a fine fibrovascular stroma. The nuclei were shown around with vesicular chromatin. The eosinophilic flocculet material ,vacuole and eosino-philic inclusion body could be seen in the cytoplasm of tumor cells. Conclusion The RCC cases with negative expression of SDHA and SDHB protein have unique histological features ,with significantly higher incidence in the left kidney than that in the right kidney.

Objective To investigate the radiological characteristics and the relationships between the parameters by X?ray and direct magnetic resonance arthrography (dMRA) in non?completely dislocated dysplasia hips. Methods We retro?spectively reviewed patients (above 13 years old) with dysplasia hips from August 2009 to August 2012. These patients were classi?fied as Hartofilakidis typeⅠand typeⅡ. 188 patients (274 hips) involved 28 males (30 hips) and 160 females (244 hips), average aged 27.3 years (range 13-47 years). Standard pelvic A?P, bilateral 65° oblique X?rays, and dMRA were conducted in each pa?tient. Lateral central?edge angle (LCE), anterior central?edge angle (ACE), femoral neck?shaft angle (FNSA), and tonnis acetabu?lar index (AI) angle were measured based on the X?ray. The dysplasia hips were classified into 4 grades (GradeⅠ:CE 11°-20° , GradeⅡ:CE 1°-10°, GradeⅢ:CE-9°-0°, and GradeⅣ:CE≤-10°). Femoral neck anteversion angle (FNA), labral tear, labral inversion, and labral cyst was observed on dMRA films. Variance analysis and rank correlation were applied to find the relation?ship between CE grades and the relevant parameters by using SPSS 19.0. Results LCE has negative correlation with AI and grade of osteoarthritis, and has positive correlation with age, ACE. However, there was no relationship between FNSA and FNA. There was significantly different in Shenton's line, labral tear, labral inversion, cartilage lesion, among different grade of LCE. Conclusion LCE is an important parameter used in evaluating for dysplasia hips without complete dislocation. LCE can reflect age of onset, ACE, AI angle and degree of joint damages. Evaluation for the severity of non?completely dislocated dysplasia hips can be conducted according to grades of CE.

In this study, UPLC-MS/MS was adopted to determine the contents of five ephedrine alkaloids (Norephedrine, Norpseudoephedrine, Ephedrine, Pseudoephedrine, Methylephedrine) in plasma and urine in rats after the combined administration of Ephedrae Herba-Gypsum Fibrosum and calculate relevant pharmacokinetic parameters, in order to discuss the effect of the combined administration of Ephedrae Herba-Gypsum Fibrosum on plasma pharmacokinetics and urinary excretion characteristics. According to the results, after being combined with Gypsum, the five ephedrine alkaloids showed similar pharmacokinetic changes, such as shortened t(max), accelerated absorption rate, but reduced AUC(0-t) and V(z)/F, which may be related to the increase in urine excretion. Besides, Gypsum was added to enhance C(max) of Pseudoephedrine and prolong MRT(0-t) of Methylephedrine, so as to enhance the anti-asthmatic effect of Ephedrae Herba and resist the toxic effect of Norephedrine and Ephedrine. This study proved the scientific compatibility of Ephedrae Herba-Gypsum Fibrosum and provided a reference for studies on the prescription compatibility regularity and relevant practices.

Objedtve To summarize the experience of single-stage repair of coarctation of aorta(CoA) or interrupted aortic arch (IAA)and associated intracardiac defects through median stemotomy.Methods From Jan 2007 to Jul 2008,a total of 24 pa-tients with CoA or IAA and associated intracardisc defects were surgically repaired in single-stage through median stermotomy,inchud-ing 9 coanctation of aorta,12 coarctation with aortic arch hypoplasia,and 3 interrupted aorlic arch,.The associated intracardiac de-fects were Taussing-Bing anomaly 4,non-restricted VSD 22,subaortic stenosis 1 and pulmonary vein stenosis 1.The age ranged form 1 to 99 months (average 16 months) and the body weight ranged from 4 to 19 kg(average 9.3 kg).Aortic arch reconstruction was performed by hypothermic continuous low flow bypass using regional perfusion for all patients.Three patients with LAA and 9 patients with CoA underwent end-to-end ansetomosis.Of the 12 patients with coarctation and aortic arch hyipoplasia,8 patiellts underwent ex-tended end-to-end anastomosis,2 patients underwent end-to-side anastomosis and 2 patients underwent aortoplasfy.Results 2 cases were dead. One infant with Taussig-Bing type heart was dead of severe infection after 47 days postoperative,the other one who associ-ated with LAA and VSD dead of pulmonary hypertension crisis due to pneumonia after 15 days postoperative.No patient presented neu-rdogieal complication and renal insufficiency during the perioperation.2 cases presented recurrent respiratory problem.During the 18months follow-up,no patient presented with recoarctation except one with pressure gradient more than 20 mm Hg.Conclusion Pa-tients with coarctation of aorta or interrupted aortic arch and associsted intracardisc defects should be surgically treated as early as pos-sible when diagnosis was mode.Single-stage sortic arch reconstruction through median stemotomy using continuous regional perfusion is an effective and safe procedurd.Sufficient resection of ductus,extensive dissection of thoracic vessels and optimal tissus-tissue anas-tomosis techmique are very important for successful repair and avoiding recoarctation.

Objective To discuss the mid?to long?term results and possible prognostic factors of Bernese periacetabu?lar osteotomy for adolescents and young adults with developmental dysplasia of the hip. Methods Bernese periacetabular os?teotomy was performed on 162 patients (171 hips) with hip dysplasia from August 1997 to July 2009. Follow?up data was ac?quirable completely in 123 cases (137 hips), including 30 males (33 hips) and 93 females (104 hips). Age of surgery was 12-48 years (average 27.1 years). The X?ray radiographs and Harris scores were recorded preoperatively and at the last follow?up. The lateral center?edge angle (LCE), acetabular incline angle (AI), continuity of Shenton's line were also recorded. The grades of the hip osteoarthritis were classified by T?nnis classification. Insufficient corrections of osteotomy, excessive corrections of osteotomy, nonunion of the pubis, nerve injuries, and vascular injuries were recorded as complications. Results All the con?tactable cases was followed up again in June and July in 2014. Follow?up duration was 5-17 years (mean, 8.1 years). The LCE angle improved from 7.13° ± 8.86° preoperatively to 30.17° ± 14.98° at the final follow?up. The T?nnis acetabular incline angle decreased from 27.84° ± 12.85° preoperatively to 7.06° ± 10.58° at the final follow?up. The continuity of Shenton's line was in?tact in 106 cases postoperatively, compared with 87 cases preoperatively. Harris score improved from 83.34±9.82 preoperative?ly to 92.79±7.05 at the last follow?up. There was significant correlation between preoperative Harris score and Harris score at the last follow?up. Early complications were observed in 15 cases (15 hips), along with 17 cases (17 hips) of progressions of hip osteoarthritis. Survival rate of the hip at the last follow?up was 97.8%. Conclusion Bernese periacetabular osteotomies can significantly improve bone coverage and joint function of hip dysplasia patients with low rate of short?term complications. Further?more, there was little osteoarthritis progression observed, with good survival rate of the joint in mid?to long?term follow?up. Lower pre?operative Harris scores and higher pre?operative T?nnis classifications are important prognostic factors for post?operative pain.

OBJECTIVETo elucidate the molecular mechanism of Wendan Tang in prevention of lipid metabolism disorder in adult rats.
METHODOn the basis of hyperlipidemia rat models, triglycerides (TG), total cholesterol (TC) in serum, activities of lipase (LA), lipoprotein lipase (LPL), hepatic lipase (HL) in liver, parts of hemogram and hepatic LDLR mRNA levels were investigated 21 days after the feeding of atherogenic diet.
RESULTWendan Tang significantly reduced the serum TG, TC and increased the activity of LPL and LA, but caused no chang in HL. The result of RT-PCR test showed that high fat and high cholesterol feeding could significantly induce the reduction of LDLR mRNA levels, while Wendan Tang could increase hepatic LDLR density.
CONCLUSIONWendan Tang can prevent disorder of lipid metabolism by regulating TC, TG, LDL-c through upregaulation of LDLR transcription level and improving antioxidant ability.
