Objective To investigate the clinical application value of hand-assistant laparoscopy and total laparoscopy in radical right colectomy.Methods Five hundred and twenty-four patients were selected as our subjects who performed by hand-assistant laparoscopic radical right colectomy (213 cases) or total laparoscopic radical right colectomy (293 cases) in colon cancer therapy.The operation durations,bleeding volumes,postoperative pain scores,postoperative draining volumes,recovery time of gastrointestinal function,hospitalization times,hospitalization expenses,postoperative complications and cosmetic satisfactory scores were recorded and compared.Results The operation durations,bleeding volumes,postoperative draining volumes in hand-assistant laparoscopic group were (112.4±52.9) min,(105.6 ± 49.5) ml,(28.6± 15.7) ml,lower than those in total laparoscopic group((148.5±61.7) min,(171.5±72.4) ml,(28.6±15.7) ml;P=0.032,0.041,0.039).The recovery time of gastrointestinal function of hand-assistant laparoscopic group were (69.4±21.8) h,longer than total laparoscopic group ((53.4 ± 21.7) h;P =0.008).The hospitalization times,hospitalization expenses,postoperative complications of hand-assistant laparoscopic group were as same as total laparoscopic group(P＞0.05).Hand-assisted laparoscopic group mild pain in 35 cases,121 cases of moderate and severe 75 cases;Total 96 cases of mild pain in laparoscopic group,146 cases of moderate and severe in 51 cases,the difference was statistically significant(P=0.027).Beauty score incision of laparoscopic group was higher than in the whole hand-assisted laparoscopic group,the difference was statistically significant ((4.3 ± 0.9) score vs.(2.4±0.6) score;P=0.002).Conclusion Hand-assistant laparoscopic radical right colectomy is convenient and more quickly for operation.Total laparoscopic radical right colectomy has advantage in terms of less injury and the patients are more satisfactory.For practiced operators,total laparoscopic radical right colectomy is recommended cosmetic satisfactory score.

Objective To evaluate the image quality of dynamic three-dimensional contrast enhanced ultrasonography(3D-CEUS) in liver tumors.Methods Twenty-five patients were examed with 2D-CEUS and dynamic 3D-CEUS.Contrast-enhanced computed tomography or magnetic resonance imaging(CECT/MRI) were performed early or late.Two readers reviewed the images of both modalities and graded the images according to diagnostic criteria as follows:tumor blood fusion in arterial phase(unclear-score 0,moderate-score 1,clear-score 2),tumor boundry and relationship with periphery tissues (unclear score 0,moderate-score 1,clear-score 2).The concordance between the two modalities for showing liver tumors was evaluated by Kappa test.Results Twenty-three of 25 danymic 3D-CEUS were displayed successfully versus total objects in CECT/ MRI.Among them,for showing blood fusion,16 lesions scored 2,7 lesions scored 1,2 lesions scored 0 in danymic 3D-CEUS,meanwhile 18 lesions scored 2,7 lesions scored 1,0 lesion scored 0 in CECT/MRI,the Kappa value was 0.65.For showing tumor boundry and relationship with peripherytissues,16 lesions scored 2,7 lesions scored 1,2 lesions scored 0 in danymic 3D-CEUS,meanwhile 21 lesions scored 2,4 lesions scored 1,0 lesion scored 0 in CECT/MRI,the Kappa value was 0.52.Conclusions Danymic 3D-CEUS was shown to be useful for displaying tumor blood fusion,boundry and relationship with periphery tissues in single liver tuomor,the concordance between dynamic CEUS and CECT/MRI for single liver tuomor was fair.For huge liver tumor and multi-tumors,3D-CEUS can not give overall information.

Objective To compare the application of Goldman , CARPREG and ZAHARA in predicting cardiac outcomes in pregnant women with congenital heart disease. Methods A retrospective analysis of 144 pregnant women with CHD , enrolled in The Third Affiliated Hospital of Guangzhou Medical University between Jan 1992 and June 2015 was conducted. The mortality and the incidence of cardiac events were counted by three risk estimation methods. The sensitivity and calibration of three systems were compared by using Hosmer-Lemeshow goodness of-fit analysis and Aera Under Curve (AUC). Results In terms of mortality rates, the sensitivity of CARPREG was higher than that of Goldman (AUC:0.874 and 0.889 respectively;P = 0.568 >0.05);. In terms of the incidence of cardiac events, the sensitivity of ZAHARA was higher than that of Goldman (AUC:0.912 and 0.773 respectively;P = 0.063 > 0.05); Conclusions All 3 risk estimation methods have good performance in sensitivity of predicting the incidence of cardiac events and mortality in pregnant women with CHD. The ZAHARA has a better calibration in predicting the incidence of cardiac events , and we recommend ZAHARA as the first choice of evaluation system for this kind of patients.

Objective To evaluate the feasibility and advantages of robot-assisted laparoscopic radical prostatectomy (RALRP) in treating high-risk prostate cancer.Methods From Mar.2010 to Dec.2014,69 men with high-risk prostate cancer (clinical stage ≥ T3a,serum PSA ≥ 20 μg/L or biopsy Gleason score ≥8) underwent surgical treatment at our center.RALRP was performed in 44 cases,with a mean age of (66.7 ± 8.6) yrs (range:50 ～ 82) and a mean baseline PSA of (23.1 ± 11.2) μg/L (range:3.6-48.8).Transperitoneal approach was adopted in all cases.Twenty-five patients were treated with ORP.The mean age was (64.3 ± 5.9) yrs (range:52-75) and baseline PSA was (21.7 ± 10.2) μg/L (range:5.7-41.3).Baseline clinical features,including age,initial PSA,biopsy Gleason score and clinical staging,were comparable between two cohorts.Surgical outcomes after RALRP were analyzed and compared between groups.Results All RALRP procedures were successfully performed with da Vinci robotic system and there was no open conversion.Mean operation duration were similarly (158 ± 47)min for RALRP group and (152± 42)min for ORP group,respectively.The mean estimated blood loss and postoperative length of hospital stay in RALRP group were (328 ± 254) ml and (8.4 ± 3.1) days,both of which were significant lower than those in ORP group,(674 ± 302) ml and (14.4 ± 3.7) days.Two cases of urine leak and two of lymphatic leak occurred after RALRP,and a statistically insignificantly higher complication rate was observed for the ORP group,in which four of urine leak and three of lymphatic leak happened.The positive surgical margin rates of two groups were 20.5％ and 24％,respectively.After the mean follow-up of 25 (RALRP) and 27 months (ORP),continence rate was significantly higher in the RARLP group (93.2％ vs.72.0％).PSA failure was observed in seven RALRP cases (15.9％) and four ORP cases (16.0％).Conclusion Compared with traditional ORP,RALRP shows significant advantages,including less blood loss,fewer complications,shorter length of stay,better postoperative continence and equivalent oncologic outcome when dealing with high-risk prostate cancer cases.Robot-assisted surgery is a safe and efficacious surgical modality in this setting.

Objective To explore the role and clinical significance of GSTM 3 ( glutathione S-trans-ferase mu 3) expression in prostate cancer (PCa). Methods We had used the two-dimensional fluores-cence difference gel electrophoresis ( 2D-DIGE) and mass spectral analysis to further verify the microarray data of mRNA expression profiling discovered .GSTM3 mRNA level was detected by Rael-time Quantitative PCR ( RT-QPCR) in 28 pairs of prostate cancer tissue and benign tissue .The relationship of GSTM 3 level with the serum PSA level and the clinical feature of PCa were analyzed . Results In 2D-DIGE study, we found that the expression of GSTM 3 protein in adjacent tissues was significantly higher than that in PCa tis-sues (P<0.05).RT-QPCR results showed that GSTM3 in adjacent tissues (8.12±0.51) was significantly higher than that in PCa tissues (7.18±0.54) (P<0.05).There was no significant difference of GSTM3 ex-pression in different serum PSA packets ( P>0.05) and prostate cancer clinical pathological parameters ( P>0.05). Conclusions GSTM3 expression is down-regulated in PCa tissues, and we may identify PCa by detecting the GSTM 3 expression .

BACKGROUND:It is important to establish an ideal mouse model of severe aplastic anemia for investigating the mechanism and finding new therapies for aplastic anemia. OBJECTIVE:To establish a severe aplastic anemia mouse model by using recombinant human interferon-γand busulfan. METHODS:Sixty healthy Kunming female mice were randomly divided into two groups:model group (n=50) and control group (n=10). The model group was given recombinant human interferon-γat a dose of 1×104 U/d by intraperitoneal injection and busulfan at a dose of 18 mg/(kg·d) through stomach feeding for 7 days. The same volume of physiological saline was given to control group. Multi-parameters, including general condition, body weight, blood cellcount, morphology and biopsy of bone marrow were analyzed in two groups. RESULTS AND CONCLUSION:At day 7 after treatment, the weight, white blood cellcount, hemoglobin, blood platelet, reticulocyte count in model group were significantly lower than control group (P<0.05). Bone marrow smears and biopsy of model group showed marked reduction of bone marrow proliferation and increases of percentages of non-hematopoietic cellclusters and adipose tissue. The oil drop and fat vacuole were apparently seen in the model group. Severe aplastic anemia mouse model can be established by using recombinant human interferon-γand busulfan successful y, which is economic, stable and easy to operate.
