Objective To investigate clinical value of anti-adhesion agent:chitosan in preventing adhesions followed by laparotomy surgery in obstetrics and gynecology.MethodsFrom Jan.2006 to Dec.2009,770 patients underwent laparotomy surgery at Department of Obstetrics and Gynecology in the Second Affiliated Hospital of Harbin Medical University.One hundred and twenty-five patients underwent secondary surgery due to disease recurrence or cesarean section,the previous surgery were 18 cases with myomectomy,20 cases with endometriosis surgery,5 cases with resection of pelvic abscess,20 cases with ectopic pregnancy surgery,27 cases with benign adnexal neoplasm resection,9 cases with cyto-reductive surgery in ovarian cancer,26 cases with variable infertility surgery.Those 125 patients were managed by different agents washing before abdomen closure,which were assigned into two groups,including 59 cases washed by saline in control group and 66 cases washed by chitosan in study group.The abdomen adhesion in secondary surgery was evaluated by adhesion classification system.Results In study group,37 patients without adhesions,20 patients with degree Ⅰ adhesion,6 patients with degree Ⅱ adhesion,3 patients with degree Ⅲ adhesion,and no patients with degree Ⅳ adhesion were observed.While in control group,there were 11 patients without adhesions,23 patients with degree Ⅱ adhesion,14 patients with degree Ⅱ adhesion,8 patients with degree Ⅲ adhesion,and 3 patients with degree Ⅳ adhesion.The distribution of adhesion reached statistical significance between the two groups (x2 =20.9999,P =0.0003 ).Twenty-six patients in previous surgeries due to infertility included 17 cases in control group and 9 cases in study group.They all were managed by cesarean section in secondary surgery,it was found that 15 cases without adhesion and 2 cases with degree Ⅰ adhesion were in study group and 2 cases without adhesion and 7 cases with degree Ⅰ adhesion were in control group.It reached statistical difference ( P =0.0016 ).ConclusionAnti-adhesion agent could prevent adhesion followed by surgery in obstetrics and gynecology effectively.

Objective To study the relationship between the serum level of cholinesterase (CHE) and patient's clinical characteristics and serum levels of lactic dehydrogenate(LDH) and β2-microglobulin (β2-MG) in non-Hodgkin lymphoma(NHL) patients. Methods The levels of CHE, LDH, β2-MG were detected with rate method and immunoassay respectively in 74 patients, and then these patients were divided into low (38 patients) and high level groups (36 patients) according to the serum CHE levels, compared with clinical characteristics and serum levels of LDH and β2-MG between the two groups. Results There were a significant difference in serum levels of CHE, LDH, β2-MG between the low and the high CHE level group [(3714.2 ±1207.1) U/L, (435.7±364.4) U/L, (4.3±2.9) mg/L; (7898.2± 1550.5) U/L, (247.4±134.8) U/L, (2.7±1.2) mg/L, respectively] (t =10.510, P =0.000; t =2.969, P =0.005; t =3.043, P =0.004, respectively). There were no statically significance in age, pathology type, leukocyte and platelet between the low and high serum CHE level groups (t =0.166, P =0.868; x2 =0.751, P=0.386; t =1.626, P=0.111; t =1.987, P=0.056, respectively). Patients with low CHE level group were mostly in Ann Arbor Ⅲ-Ⅳ period (x2 =9.394, P =0.024) and mostly male patients compared with the high CHE level group patients (x2 =5.432, P =0.020). The quantity of hemoglobin in the low CHE level group(97.6±25.8) g/L were lower than that of the high level group (113.4±15.2) g/L (t = 3.230, P =0.002). Conclusion The low CHE level was not correlated with age, pathology type, leukocyte and platelet, but was related with male, Ann Arbor Ⅲ-Ⅳ period, anemia, and higher expression of LDH, β2-MG.

Objective To investigate the value of multi-slice spiral CT in the diagnosis of small lung adenocarcinomas. Methods Fourteen patients underwent thin multi-slice spiral CT scan. Images were post-processed and 2 kinds of postprocessing images including multiple planar reconstruction (MPR) and minimum intensity projection (MinIP) were performed. The image characteristics of the tumors assessed by multi-slice spiral CT were correlated with the clinical/pathological manifestation. Results In 14 cases of small lung adenocarcinoma, tumor density had two forms. Four of five cases with localized bronchioloalveolar carcinoma (LBAC) showed total or partial ground-glass opacity, and 9 adenocarcinomas showed solid attenuation. 3 cases with LBAC showed partial ground-glass opacity mixed with airway dilatation. MPR in 14 patients clearly showed interlobar pleura and image characteristics of the tumors. MinIP in 10 cases were able to demonstrate 5～6 scale bronchial divisions and presented air bronchogram of tumors in a vivid way. Conclusion Thin multi-slice spiral CT scan and reconstruction images can play an important role and are the valuable method in the diagnosis of small lung adenocarcinomas.

Aerosol and splatter formed during dental procedure were collected pre and post rinsing with Xipayi mouth rinse or 1% H2O2,cultured 48 hours with blood agar plates,counted the bacterial colonies.Both groups were effective in reducing bacterial aerosols(P 0.05).Bacterial aerosols by dental procedure can be reduced by using mouthwash pre-operationally,both Xipayi mouth rinse and 1% H2O2 are effective mouthwashes.

Objective To evaluate which b value is the best to distinguish the glioma recurrence and radiation-induced brain injury using DWI when b value were at 1 000 s/mm2、3 000 s/mm2 and 5 000 s/mm2 respectively.Methods Retrospective analysis the DWI of 21 patients who suffered from glioma recurrence and radiation-induced brain injury obtained on a 3T MRI scanner.Results (1)All recurrent glioma (100%)showed hyper-intense signal,while most radiation-induced brain injury patients (80%)showed hypo-in-tense signal when b=5 000 s/mm2 .The sensitivity and specificity were high (100% and 80% respectively)when hyper-intense sig-nal was taken as a diagnostic point of glioma recurrence and radiation-induced brain injury.(2)The receiver operating characteristic (ROC)curve analysis suggested that the minimum ADC resulted in a highest sensitivity to differentiate glioma recurrence from radi-ation-induced brain injury when b=5 000 s/mm.Conclusion High b-value is more accurate to reflect cell density,and the minimum ADC is better to differentiate the glioma recurrence and radiation-induced brain injury when b=5 000 s/mm2 on DWI.

Background and purpose:Ovarian cancer is one of three common malignant tumors in the female reproductive system,whose mortality is the highest in all of the gynecological cancers.The genetic instability and hypermutation rate of tumor cells were found to be associated with chemotherapeutic resistance,and accounted for the high recurrence rate and the failure of current treatment.Invasion and metastasis of tumor are closely related to angiogenesis.Experiments in vivo and in vitro have confirmed that there are many kinds of promoter and suppressor of angiogenesis in primary malignant tumor cells.Angiogenesis could be a potential molecular target for cancer treatment.Endostatin is a specific inhibitor of vessel endothelium.Animal experiments have confirmed that Endostatin could inhibit tumor growth through anti-angiogenesis and result in the decrease of invasion and metastasis of cancer,and it would not easily induced drug resistance in the cells.Thus Endostatin could be safely used for a variety of cancer treatments,being able treat any patho-angiogensis.Recently it has been reported that Endostatin may significantly enhance anti-tumor effects when it is combined with traditional treatment methods such as surgery,chemotherapy,radiotherapy and immunotherapy.Although the study of Endostatin was done in vitro,the primary results were very encouraging and provide the rationale for future clinical trials.In this study,we aim to evaluate the inhibitory effect of Endostatin on SKOV_(3) cell and to investigate the possible mechanism of the inhibition.Methods:1.The effects of Endostatin on SKOV_(3) cells proliferation was studied by means!of MTT.2.The cell apoptosis and cell cycle were detected by transmission electron microscope and cell flow cytometry.3.bcl-2 and bax expression were determined in SKOV_(3) cell by immunocytochemistry,RT-PCR and Western blot analysis.Results:Endostatin inhibited SKOV_(3) cell proliferation,and the value of A_(490) of 15?g/ml 72 h Endostation group(0.454) was much lower than that of PBS control group(1.369)(P
