1.Establishment of Modified Chronic Lung Lymph Fistula in Chongqing Goats
Journal of Third Military Medical University 1984;0(01):-
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.

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.

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.

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 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 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 analysis the relationship between of waist-to-height ratio(WHtR) and the non-alcoholic fatty liver disease(NAFLD).Methods A total of 7 896 were selected as observed subjects from the Kailuan Group in 2011-2012 health physical examination.A questionnaire survey,blood biochemical and abdominal ultrasound examination were finished by trained medical staff.According to previous study recommended cut points the observed subjects was divided into two groups:abdominnal obesity group(WHtR≥0.5,n=3 185) and non-abdominnal obesity group(WHtR<0.5,n=479).According to the WHtR and its quartile,the observed subjects was divided into four groups(first(WHtR<0.47),second(0.47≤WHtR<0.51),third(0.51≤WHtR<0.55) and forth(WHtR≥0.55) quartile groups).NAFLD detection rate of the four groups were Compared.Multiple Logistic regression analysis was used to analyze the influencing factors of the NAFLD.Results (1)The detection rate of NAFLD in abdominnal obesity group was higher than that in non-obesity group(62.7% vs.21.5%,P<0.01).Along with increasing WHtR level in the 4 quartile groups,the incidence of NAFLD was progressively increased,being 12.6 %,38.1%,57.5% and 72.5% respectively in the total population.After stratified by gender,15.1%,40.6%,59.6% and 75.0% in male,7.8%,31.5%,48.3% and 63.8% in female.In the same WHtR group,the NAFLD detection rate of male was higher than female,the differences were statistically significant(P<0.01).(2)Multiple logistic regression analysis showed that compared with the first quartile group,the second,third and forth quartile groups had increased risk of NAFLD after adjusting age,gender and other risk factors,the OR value being 3.19,5.93 and 9.81 in the total population.After adjusting above factors,the OR value being 3.12,6.02 and 10.45 in male,3.32,5.37 and 7.57 in female,respectively.Conclusion The incidence of NAFLD is increased along with the increasing the WHtR.
