Objective To evaluate the significance of fiberoptic bronchoscopic brush cytology in the diagnosis and histological classification of lung carcinoma.Methods Data of 309 patients with lung carcinoma were retrospectively analyzed.Both bronchoscopic cytology and histology diagnosis were available.The positive rate of bronchoscopic cytology and tissue biopsy were calculated respectively.The classification accuracy of cytological diagnosis for lung carcinoma was evaluated.In tissue biopsy standard,evaluated the significance of bronchoscopic cytology in diagnosis and histological diagnosis.Results The positive rate of bronchoscopic cytology and tissue biopsy were 86.1％ (266/309) and 83.8％ (259/309),respectively.Bronchoscopic cytology combined with bronchial biopsy could obviously improve the positive rate to 94.2％ (291/309) in lung carcinoma diagnosis.Taking the tissue biopsy histological type as a standard,the cytotyping accuracy for brush method was 85.1％(74/87) in squamous carcinoma,82.4％(108/131) in adenocarcinoma and 100％(11/11) in small cell carcinoma for higher.However,the accuracy in diagnosing poorly differentiated carcinomas was only 12.2％ (5/ 41).Conclusion Fiberoptic bronchoscopic brush cytology plays an stable and important role in diagnosing lung carcinomas and histological type determination.However,it has limited use in diagnosing poorly differentiated carcinomas.

Objective To assess the clinical efficacy of laparoscopic uterine artery blockage for the treatment of adenomyosis. Methods Laparoscopic uterine artery blockage was performed in 38 patients with adenomyosis. Enucleation and excision or vaporization of endometriosis were performed at the same time in patients with chocolate cyst of ovary and endometriosis. Lysis of adhesion and presacral neurectomy were performed in some patients. Symptoms and uterine volumes of all patients were investigated after the treatment. Results Relieved clinical symptoms were found in all 38 patients. Menorrhagia was reduced to (56?16)%. Complete disappearance of dysmenorrhea was found in 17 patients (44.7%), significantly alleviated in 14 patients (36.8%), partially alleviated in 6 patients (15.8%), but ineffectiveness in 1 patient (2.6%). Pain score and classification were decreased significantly (P

Objective To investigate the effects of ursodeoxycholic acid (UDCA), dexamethasone (DEX), and S adenomethionine (SAMe) on the pregnant rats with intrahepatic cholestasis induced by ethinylestradiol (EE). Methods A total of 50 15 day pregnant Wistar rats were randomly divided into five groups: control group, EE group, UDCA group, DEX group, and SAMe group. In EE group, rats were subcutaneously injected with EE (2.5 mg?kg -1 ?d -1 ) for 5 d. In the control group, rats received subcutaneous injection of appropriate volume of propylene glycol (PG) for 5 d. In UDCA, SAMe, and DEX groups, rats were administered with the same dose of EE plus UDCA (100 mg?kg -1 ?d -1 ), SAMe (100 mg?kg -1 ?d -1 ), and DEX (1 mg?kg -1 ?d -1 ) for 5 d, respectively. The serum levels of aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatases (ALP), glycocholic acid (GC), and total bilirubin were measured after cesarean. Morphologic changes of the liver of pregnant rats and the growth and development of the fetal rats were observed. Results The serum levels of ALT, ALP, GC in rats of UDCA group were decreased significantly as compared with those in DEX group ( P

Objetcive To analyze the contrast-enhanced ultrasound (CEUS)features in clear cell renal cell carcinoma (CCRCC) of different size and to discuss the diagnostic value of CEUS in CCRCCs. Methods The contrast-enhanced and conventional US features of 80 CCRCCs confirmed pathologically were retrospectively analyzed. Samples were divided into three groups by diameters: small CCRCCs (≤30 mm), medium CCRCCs(＞30 mm) and large CCRCCs(＞50 mm). The tumoral vascularity, lesion homogeneity and presence of an anechoic rim were observed on conventional US. The enhancement of echogenicity, homogeneity and pseudocapsule were evaluated on CEUS. Results Among the 80 renal masses, 32 were small CCRCCs, 28 were medium CCRCCs while the large CCRCCs were 20. On conventional US, 18.8%(6/32) of small CCRCCs, 71.4%(20/28) of medium CCRCCs and 95%(19/20) of large CCRCCs demonstrated as heterogeneous and the differences were highly statistically significant, whereas there were no differences in the tumoral vascularity and the presence of pseudocapsule sign among the three groups. On CEUS, 28.1%(9/32) of small CCRCCs, 85.7%(24/28) of medium CCRCCs and 100%(20/20) of large CCRCCs showed a homogeneous enhancement. The incidence of pseudocapsule sign in medium tumors was higher than small and large groups(71.4%,50% and 25%,respectively). There were statistically significant differences among the three groups in the enhanced homogeneity and the presence of pseudocapsule sign. However, all the three groups revealed mainly isoechoic and hyperechoic and there were no differences among them. Compared with conventional US, CEUS depicted significantly the increased tumoral vascularity (51.3% vs. 87.5%) and pseudocapsule sign(22.5% vs. 51.3%). Eight lesions demonstrated heterogeneous contrast enhancement on CEUS while homogeneous on conventional US, but there were no differences in lesion homogeneity between conventional US and CEUS findings. Conclusions Different sizes of CCRCC showed distinct CEUS features in the enhanced homogeneity and the presence of pseudocapsule sign. CEUS is more effective on improving the sonographic characteristics of tumoral visualization and may provide important information of US findings for the diagnosis of renal cell carcinoma.

Objective To construct an expression plasmid carrying the specific siRNA of survivin gene,and to evaluate its silencing effect on the expression of survivin gene and its inhibition effect on the growth of gastric cancer cells.Methods The specific siRNA of survivin gene was designed and synthesized,and an expression plasmid pAdGFP-siRNA was constructed.Gastric cancer cell line SGC-7901 was cuhured and transferred with pAdGFP-siRNA,then the silencing of survivin gene expression and the growth inhibition of cancer cell mediated by pAdGFP-siRNA were identified.Results The growth of gastric cancer cells was inhibited after transferring the pAdGFP-siRNA,with the inhibition rate of 68.2% compared to the control group.Immunohistochemistry showed that the specific siRNA markedly silenced the expression of survivin gene in cancer cells.Conclusions The overexpression of survivin gene in gastric cancer cells results in the high proliferation and the resistance to the chemo- and radio-therapy of the cancer cells.The specific siRNA can markedly silence the expression of survivin gene and inhibit the growth of cancer cells.

AIM: To examine the effect of acrylic ester and thermosol respectively as pressure sensitive adhesive matrix of zhitong huoxue extract ( Rhizoma Corydalis,Radix aconiti,Radix Paeoniae alba,Radix et notoginseng ginseng,etc) on the dissolution of effective constituent from zhitong huoxue extract.METHODS: The in vitro release experiment was carried out on Permcell diffusion cell,HPLC method was applied to determining the cumulative elease rate of tetrahydropalmatine,aconitine,paeoniflorin and ginsenoside Rg_1 from zhitong huoxue pressure sensitive adhensive.RESULTS: The acrylic ester matrix had sound controlled release profile in vitro of alkaloid components.In KT-A thermosol matrix,the in vitro release rate proved to be inversely proportional to the molecular weight (R = 0.91 ) of the effective constituents,while the 2501 s matrix presented a steadily cumulative release rate over 12 h (30% -43% ).CONCLUSION: Good release rates are observed with effective constituent with small molecular weight,adhesive composition of matrix has an obvious effect on the in vitro release behavior of zhitong huoxue extract.

Objective To report our surgical experience in treating 19 cases of solitary iliac aneurysms (SIA). Methods The clinical data of 19 consecutive patients with SIA between January 1985 and January 2008 were retrospectively reviewed. There were 18 men and 1 woman, aging from 39 to 77 years ( mean 62 ± 7 years). Results There were 30 SIAs in the 19 patients, including 25 ( 83.3% ) common iliac aneurysms, 4 (13.3%) internal ihac aneurysms and 1 (3. 3% ) external iliac aneurysm. Eleven patients ( 57.9% ) had multiple ancurysms, with 9 patients ( 47.4% ) having bilateral SIA. Two patients had coexistent peripheral vascular occlusive disease. There were 2 patients suffering form ruptured SIA, one was saved by emergency operation and one died before an surgery could be attempted. Seventeen patients underwent successful open aneurysmectomy and artificial graft implantation leaving no ischemic complications of the pelvic organs. One patient with right common iliac aneurysm underwent endovascular repair without endoleak. There was no operative death during porioperative period. The surviving patients remained stable and had good patency of grafts during the follow-up period. Conclusions Early management of SIA is important, CT angiogarphy (CTA) is necessary not only to evaluate the SIAs, but also to detect multiple aneurysms or arterial occlusive disease. Close and long-term follow-up is mandatory for the early detection of the formation of new anearysms.

OBJECTIVETo explore the relationship between blood stasis (BS) syndrome and coronary lesion in patients with coronary heart disease (CHD).

METHODSSyndrome types of 500 patients collected from multiple centers whose diagnosis of CHD confirmed by coronary angiography were differentiated. And the relationship between BS syndrome, its subtypes, and coronary lesion (affected branches, degree of constriction) were analyzed.

RESULTSThe affected branches of coronary artery in patients of BS syndrome was 2.28 +/- 0.28, while that in the non-BS syndrome patients was 2.07 +/- 0.86, showing significant difference between them (P < 0.05); as compared to patients of non-BS syndrome, the coronary lesions in patients of BS syndrome were mostly multi-vascular, and of more severe degree (P < 0.05). In patients of various BS syndrome subtypes, the average number of affected coronary branches in patients of yang-deficiency subtype was 2.58 +/- 0.65, which was significantly more than the number in patients of other BS syndrome subtypes. The constriction degree of coronary lesions in patients of yang-deficiency BS syndrome subtype were mostly severe or moderate, and single branch lesion was rarely seen, as compared with those in patients of phlegm-stasis obstruction subtype, the difference was significant (P < 0.05). The corresponding correlative analysis showed that close correlation was found between yang-deficiency subtype of BS syndrome and severe coronary constriction with the correlation distance of 0.1899.

CONCLUSIONRelationship between BS syndrome and coronary lesion (its number of branches and degree of constriction) truly exists to a certain extent.
