A method, which was a modification of that of Stothert et al, was adopted to establish chronic lung lymph fistula in goats from Chongqing area. The procedure consisted mainly that a segment of the thoracic duct was isolated to serve as the efferent of the caudal mediastinal lymph node to collect lung lymph, and an irrigation tube was inserted for the periodic admnistration of heparin solution to prevent the sanguinous lymph from clotting in the early postoperative days. A series of difficulties including high surgical mortality, stoppage of lymph flow, and chyle contamination of the lung lymph were overcome. A trial of the operated goats on steam inhalation injury precipitated instant increase of lung lymph f .ow and an elevation of lymph/plasma ratio of total protein concentration, which suggested that our animal model was suitable and effective in the study of the exchanges of fluid and protein in the lungs. The details of the technique were described and discussed.

AIM: To investigate the effects of RUNX3 gene on the growth and drug sensitivity of SH-SY5Y cells.METHODS: The siRNA plasmid of RUNX3 was constructed and transfected into SH-SY5Y cells.Stable transfectants were identified by RT-PCR and Western blotting.The growth curve,cell cycle distribution,drug sensitivity assay and accumulation of adriamycin in cells were detected by MTT assay and flow cytometry.The expressions of cyclin D1,CDK4,CDK6,p21,p27,Bcl-2,Bax,P-gp and MRP were analyzed by Western blotting.RESULTS: mU6pro-RUNX3 siRNA was successfully constructed and transfected into SH-SY5Y cells.Down-regulation of RUNX3 significantly promoted the cellular proliferation,inhibit the drug sensitivity and intracellular adriamycin accumulation of cells,compared with that in the controls(P

Objective:To investigate the role of early enteral nutrition in preventing functional delayed gastric emptying(FDGE)after radical distal subtotal gastrectomy.Methods:A retrospective review was performed in clinical data of patients with gastric cancer undergoing radical distal subtotal gastrectomy in our hospital from March 2004 to March 2008.There were 71 patients receiving early enteral nutrition (group EEN,n=71) after operation and 107 patients receiving parenteral nutrition (group PN,n=107) at the same time.The outcomes of FDGE between of two groups were compared.Results:The incidence of FDGE in group EEN was 1.4%(1/71).And the incidence of FDGE in group PN was 10.3%(11/107).There was significant difference between the group EEN and the group PN (P

Paget's disease of the breast is an uncommon disorder that accounts for 1% to 3% of all mammary tumors. The incidence of underlying carcinoma associated with Paget's disease has been reported in 82% to 100% of cases. The finding of underlying carcinoma reaches almost 100% when a palpable lump is also present. In this rare case, we described a patient presenting with Paget's disease but no palpable lump. However, we found 11 independent regions which were all invasive ductal carcinoma after the operation. Considering this patient, we should pay more attention to a multifocal and multicentric breast carcinoma associated with Paget's disease. Furthermore, we believe the mammography examination and a modified radical mastectomy are the most appropriate treatments for this population in clinical practice.

The results suggested that the clinical symptoms were relieved significantly without complications.Conclusion　SCL can relieve the clinical symptoms and improve the life quality of patients with bullous keratopathy significantly.

Objective To discuss the clinical application of laparoscopic ultrasound (LUS) in laparoscopic nephron sparing surgery(NSS) for central renal tumors.Methods Eighteen patients underwent laparoscopic NSS for central renal tumors.The use of LUS was mainly lay in observing the nature and size of the tumor, the minimum distance from the tumor to capsule, collective system and renal artery, tumor's vasa vasorum,tumor localization and determination of margins.Results Of the 18 central renal tumors,the size was 11 - 29 mm,23.3 mm in average.The minimum distance from the tumor to capsule was 2 - 11mm,4.7 mm in average.The minimum distance within 5 mm to collective system and to capsule was 12 and 10 cases respectively.The tumor was surrounded by nephridial tissue completely on LUS, without protruding capsule.LUS diagnosis of 18 central renal tumors: 10 cases of renal angiomyolipoma,7 cases of renal cell carcinoma, 1 case of renal cyst with capsule wall calcification (at first diagnosed as renal carcinoma by CT).The findings of LUS were same to pathologic and(or) postoperative diagnoses.The accuracy of ultrasound localization was 100％.The surgical margins of 7 cases of renal cell carcinoma were all negative.Conclusions It is of high clinical value of LUS on locating the tumor and defining tumor margins in laparoscopic resection of central renal tumors.Besides, more information on tumor and vessel supply will be achieved.

Objective To investigate the role of double contrast-enhanced ultrasonography (DCUS) in the diagnosis of rectal gastrointestinal stromal tumors (GISTs). Methods In eleven patients with rectal GISTs before surgery, gastrointestinal ultrasound contrast agent were injected into rectal lumen and tumor’s two dimensional ultrasound features were analyzed. Microbubbles were injected into the vein to investigate the feature of lesion microcirculation perfusion. After the surgery, according to the tumor diameter and mitotic count, rectal GISTs were classified as very low-risk, low-risk, intermediated-risk and high-risk tumors. The very low-risk and low-risk tumors were grouped together as one group while the intermediated-risk and high-risk tumors were grouped together as another group. According to ultrasound performance and pathological type, ultrasonic features of rectal GISTs with different risk levels were estimated. Results Among all rectal GISTs cases, 63.6%(7/11) were low-risk. Under DCUS, the tumor diameter was less than 5 cm, with regular round, hypoechogenicity, uniform low enhancement and less internal liquefaction necrosis. For the 36.4%(4/11) high-risk cases, under DCUS, the tumor diameter was≥5 cm, with irregular round or lobulation, mixed hyperechogenicity and hypoechogenicity, nonuniform high enhancement, large blood vessel and common liquefied necrosis region. The biological behavior of rectal GISTs was relevant to lesion size, liquefaction necrosis and enhancement mode of ultrasound contrast and irrelevant to the bound and shape of lesion. The accuracy of DCUS and contrast-enhanced ultrasonography were 90.9%(10/11) and 72.7%(8/11) respectively. Conclusions DCUS is considered as an effective tool in diagnosingrectal GISTs and can get useful information of the biological characteristics. It has great value for the diagnosis and treatment of rectal GISTs.

Objective To evaluate the preoperative T staging value of rectal carcinoma by using double contrast-enhanced ultrasonography (DCUS).Methods 71 patients with rectal carcinoma were examined by ultrasound after infusing contrast agent and bolus injection of SonoVue preoperatively.The border,shape and perfusion patterns of the tumor were observed.After surgery,the T staging made by DCUS and perfused contrast-enhanced ultrasonography (PCUS) was compared with final pathologic results respectively.Results The accuracy of PCUS and DCUS in determining the T stage of rectal carcinoma were 71.8％(T1 72.7％％,T250.0％,T374.4％,T476.9％) and 85.9％(T190.9％,T275.0％,T387.1％,T484.6％) respectively.The difference between these two methods was statistically significant (P ＜0.05).Conclusions DCUS is a new valuable method for T staging of rectal carcinoma with its high accuracy preoperatively.

Objective To explore the relationship between the distribution of infected snails and transmission of acute schistosomiasis in hilly regions.Methods The data concerning the distribution of the infected snails and acute schistosomiasis in Shitai County,Anhui Province from 1999 to 2008 were collected and analyzed.Results The sehistosome infection rate of human increased as the distance between the settings with infected snails and activity sites of humans shortened.Conclusions Acute infection of schistosome of human is associated with the distance between the settings with infected snails and activity sites of them.Strengthening the measures of snail control in key regions,protecting key populations and carrying out health education for schistosomiasis control are important approaches to control the transmission of acute schistosomiasis in hilly regions.

Objective To examine the sleep status and relevant psychosocial factors in patients with colorectal cancer before surgery and improve their sleep quality. Methods A cross?sectional survey method was used. Participants were 107 cases of patients with colorectal cancer from the Department of Anorectal Surgery in The First Hospital ,which is affiliated with China Medical University. The Athens insomnia scale(AIS),Ham?ilton depression scale(HAMD),Hamilton anxiety scale(HAMA),perceived social support scale(PSSS),self?esteem scale(SES),medical cop?ing questionnaire(MCMQ),memorial University of Newfoundland scale of happiness(MUNSH),Eysenck personality questionnaire(EPQ),and Wong?Baker face scale were used to assess preoperative sleep in patients with colorectal cancer and related psychosocial factors. Results Among the 107 cases,there were 24 cases of insomnia,with an insomnia incidence of 22.43%. No statistical differences were found in demographic charac?teristics and clinical characteristics(P>0.05). According to the degree of insomnia,there were significant differences between groups(P<0.05) for depression,anxiety,social support,avoidance,yield,happiness,and EPQ?N. Before the surgery,the degree of depression,anxiety,and EPQ?P had a significant positive effect on the degree of insomnia (P< 0.05). Conclusion The degree of insomnia before surgery in patients with colorectal cancer is closely associated with depression,anxiety,coping styles,social support,and personality characteristics.
