ABSTRACT
Objective To evaluate the use of unilateral pedicle lymphography (PLG) in preoperative localization and treatment of chyluria.Methods From October 2010 to March 2017,25 cases with severe chyluria and undergoing cystoscopy and unilateral PLG before renal pedicle lymphatic disconnection were reviewed.There were 11 males and 14 females,aged 44-71 years,with an average of 58.5 years.The course of the disease was 6 months to 30 years,with an average of 8.3 years.Of them,18 cases had undergone unilateral PLG and spiral CT angiography preoperatively.Surgical treatment was performed according to PLG imaging.Results Unilateral ureteral chyluria was discovered in 16 out of the 19 cases through cystoscopy,with the sensitivity of 84.2％ (16/19).In contrast,unilateral chyluria was only detected in 4 of the other 6 patients with bilateral chyluria.Albiduria were found in the remaining 5 cases in bladder,without ureteral excreted chyle.The sensitivity for chyluria positioning by cystoscopy was 64.5％ (20/31).The location of lesion in 19 patients with unilateral chyuria and 6 patients with bilateral chyluria could be correctly displayed by PLG and the sensitivity was 100％ (31/31).There was no significant difference in location between cystoscopy and PLG in 19 patients with unilateral chyluria (P =0.2482).But in total lesion location,the sensitivity of PLG was higher than cystoscopy(P =0.0026).Eighteen patients who had undergone PLG combined with spiral CT angiography,could not only locate the chylous fistula,but also determine the number of renal vessels as well as their relationship with diseased lymphatic vessels.Chyluria had disappeared immediately after unilateral renal pedicle lymphatic exfoliation in 23 patients.However,it still presented in the other 2 patients who were confirmed contralateral pyeloymphatic fistulas by PLG 3 months after surgery and cured by reoperation.Chyluria recurred in 6 cases during follow-up of 6 to 58 months,and 4 were confirmed bilateral pyelolymphatic fistulas by PLG.Two of these 4 cases were cured by laparoscopic surgery or open surgery,respectively.The other 2 patients were cured by conservative treatment.Moreover,2 patients with unilateral chyluria recurred in situ after the first laparoscopic surgery,which was confirmed by PLG.Notably,all these patients were cured by ESWL finally.Conclusions This study suggested that PLG displays remarkable advantage in terms of localization sensitivity.PLG combined with spiral CT angiography preoperatively can not only locate the chylous fistula,but also determine the number of renal vessels as well as their relationship with diseased lymphatic vessels.Depending on PLG and spiral CT angiography,renal pedicle lymphatic disconnection can effectively protect renal vessel.In addition,it can avoid the omission of ligation for perivascular lymphatic vessels.Furthermore,PLG plays a key role in temporarily obstructing the leakage of pyelolymphatic fistulas to some extent.
ABSTRACT
Clinics are a main institutional form for doctors to open personal business in China .The develop-ment process of clinic reflects the situation of medical staff free practice .This study summarized the supervision poli-cies on clinic in China since the founding of China and got three conclusions .The first one was the attitude of the practice of the clinic has changed significantly .The change include four stages which were authorization ( 1949—1957 ) , limitations ( 1958—1977 ) , re-authorization ( 1978—1996 ) , promotion and encourage ( 1997—) along with macroeconomic system reform and the changes of government's governance ideas on health sector .The second conclu-sion was that the government gradually raised awareness of the status and role of the clinic institutions in the health system over the past several decades .The third conclusion was the supervision policies became more meticulous .In the future , clinical institutions can be a useful supplement to public medical institutions in China for its development process and characteristics .
ABSTRACT
In recent years , the increasing number of private medical institutions in China has not led to the re-sponding increase in medical services , capital asset scales .The competitive situation between public and private medical institutions has not yet been formed .This paper discusses the difficulties that Chinese private medical institu-tions have encountered in overseas capital inflow , in order to foster local private medical Institutions , as well as the development of private non-profit hospitals .Based on a systematic analysis of the key points in policy , suggestions were proposed in regarding with enhancement of top-level design of the policies , encouragement of the development of off-shore or on-shore small-scale private medical institutions , as well as facilitation of the productive factors flow in medical institutions'operation.The suggestions on the policies are to be referenced in decision making for a healthy development of Chinese private medical institutions .
ABSTRACT
There are still some flaws in the private non-profit hospital supervision system since those hospitals recently began to grow in China. The paper aims to analyze the access and changing processes from the non-profit to profit hospitals and the non-profit character supervision of the private non-profit hospitals based on the literature and survey data in Hubei, Guangdong and Jiangsu Provinces. It also puts forward some suggestions on the private non-profit hospitals development including how to optimize the access process, increase taxes or liquidation in the chan-ging process, and establish the coordination supervision mechanism for the non-profit Character in China.
ABSTRACT
By means of comparative analysis and literature review,the paper identified differences of private non-profit hospitals at home and abroad in terms of their historical background,fund-raising,tax-free qualification,and governance structure.On such basis,an analysis was made on the development paths of such hospitals in China,for theoretical references and decision support for their development.
ABSTRACT
Based on an analysis of the positioning of public hospitals and the significance of their corporate governance,the authors hold that the present corporate governance of China's public hospitals is at its startup stage.They believe that such governance is the basis to build contemporary hospital management system,yet it is not a solution for all problems confronting these hospitals.Furthermore,progress of the governance requires further optimization of the political ecology.These studies aim at providing theoretical and policy support for the ongoing reform trials of public hospitals.
ABSTRACT
Objective To understand the current status of learning motivation of high vocational nursing students, In order to increase their learning effect and teach quality. Methods 334 high vocational nursing students were investigated with college students learning motivation questionnaire, the results underwent analysis. Results High vocational nursing students had low learning motivation, their learning motivation was diversified. Significant difference existed between top students and low students. Conclusions High vocational nursing students had weak learning motivation, and is not related with grades and source places. It had individual orientation and utility color, but low social property. Learning motivation is an important factors for academic achievement.
