Objectives: To analyze the strategies of the diagnosis and treatment in patients with the pulmonary infection after renal transplantation. Methods: A retrospective analysis was made on 28 cases of pulmonary infections among 285 patients undergoing renal transplantation. Results: The morbidity of pulmonary infection was 9.82%(28/285). The majority pathogens of pulmonary infection in this study were pseudomonas, staphylococcus epidermidis, canadida and cytomegalovirus. Chest X ray was important in the diagnosis, but there was no specificity to determine the pathogens. The mortality in 28 pulmonary infection patients was 32.1%(9/28). Most of the patients suffered from pulmonary infection within 4 months after the operation, and the postoperative period from 2 months to 4 months was a high risk time window for death caused by pulmonary infections. Conclusions: The morbidity and mortality of pulmonary infections, especially severe pneumonia, in patients with renal transplantation, are higher than healthy people. Treatment following clinical epidemiology and strategy of microbiology play a very important role to reduce the mortality in those patients.

Objective To evaluate the clinical feasibility of performing the placement of drainage tube via transnasal route in treating mediastinal anastomotic fistula after surgery of esophageal cancer.Methods A total of 6 patients with mediastinal anastomotic fistula after surgery of esophageal cancer,who were admitted to authors' hospital during the period from August 2015 to January 2016,were included in this study.The diagnosis was confirmed by esophageal radiography and thoracic CT scan in all the 6 patients.Under X-ray monitoring,the drainage tube was inserted into the cavity of mediastinal fistula with the help of a guide wire guidance,and continuous negative pressure suction was adopted.The jejunum nutrition tube was inserted via the same nostril if feeding tube was not placed.Results Successful placement of fistula drainage tube and jejunum nutrition tube was achieved in all the 6 patients.In one patient the fistula drainage tube had to be re-placed as the drainage tube was obstructed five days after initial placement.Under X-ray monitoring the mean time used for the drainage tube placement was 33 min (range of 23-48 min).The procedure was well tolerated by all the 6 patients,and no procedure-related complications occurred.After continuous negative pressure suction that lasted for 6-40 days (mean of 23 days) the fistulae healed.Conclusion For the treatment of mediastinal anastomotic fistula after surgery of esophageal cancer,the placement of fistula drainage tube under X-ray monitoring is simple,safe and effective.(J Intervent Radiol,2017,26:250-252)

Objective To explore the diagnostic value of percutaneous transhepatic cholangial biopsy for malignant obstructive jaundice.Methods Data of 42 cases suspected of malignant obstructive jaundice who underwent percutaneous transhepatic cholangial biopsy and percutaneous transhepatic cholangial drainage (PTCD) were retrospectively analyzed.And during the examination,the biopsy tissues were obtained for pathology.Results The pathologic results were obtained successfully in 41 of 42 cases and the success rate of operation was 97.62％ (41/42).There were 31 cases with positive results.The positive rate was 73.81％ (31/42).In 12 cases diagnosed as distal biliary tract obstruction by percutaneous transhepatic cholangiography (PTC),positive pathology results were found in 3 cases;the positive rate was 25.00％ (3/12).In 30 cases diagnosed as perihilar biliary tract obstruction by PTC,positive pathology results were found in 28 cases;the positive rate was 93.33％ (28/30).The accuracy of perihilar biliary tract obstruction was higher than that of distal biliary tract obstruction (x2=20.704,P＜0.05).In all 42 cases,there were no severe complications during or after surgery.In the 31 cases with positive biopsy pathological results,6 cases underwent surgery after improved liver function.The postsurgical pathological results were agree with biopsy pathological results.Conclusion Percutaneous transhepatic cholangial biopsy is safe and efficient for malignant obstructive jaundice.The successful rate and positive rate are high,especially for perihilar biliary tract obstruction.

Mice was stimulated by peptidoglycan from Lactobacillus sp and detect cytokines production。It was found that PG induced the production of inflammatory cytokines (IL-1,TNF-? in peritoneal macrophages,IFN-? in spleen cell)and did not induce the IL-2 production in spleen cell. Affymetrix MOE430A genechip was used to analyze changed gene expression of immune cells. It was found that expression of cytokines and related genes were changed under peptidoglycan administration. This might induced by activation of TLR-NF-?B signal pathway.

Objective To observe the clinical effect of Yiqi Yangyin Huoxue decoction(the function of decoction is to tonify Qi,nourish Yin and enhance blood circulation)on salivary gland response attribute to radiotherapy.Methods This study,carried between January 2005 and December 2005,focused on the effect of Chinese herbs on salivary gland response attribute to radiotherapy.In the treatment group,30 cases took Chinese herbs during the duration of radiotherapy,while in the control group 30 cases were given routine therapy.Results Both groups had finished the radiotherapy,however,in the control group,there were 5 cas- es with a break for 1～2 weeks.For the comparison of the salivary gland change in acute stage,there was no variance(x~2=2.387,P=0.122);the latency for the salivary gland change in treatment group was longer than that in control group(x~2=13.106,P=0.000).For the comparison of Karnofsky after radiotherapy,the KS was superior in the treatment group than that in control group(x~2=12.685,P=0.013);For the comparison of objective effect after radiotherapy,the remission rate in treatment group was 90 %,and it was 86.7 % in control group(x~2=0.638,P=0.727).Conclusion The decoction can remit the salivary gland response caused by radiotherapy in clinic,prolong the latency for acute radioactive response;release the pain of the pa- tients,increase the achievement ratio for radiotherapy,and improve the patients'living condition.To combine with radiotherapy,Chinese herbs is a good supplemental therapy for nasopharyngeal carcinoma

OBJECTIVETo explore the feasibility of replacement of ordinary syringes by auto-disposal syringes (AD) in China.

METHODSSampling survey was conducted in Hebei province to collect data on the direct medical spending of hepatitis B and their Disability Adjusted Life Year (DALY) losses. The financial burden on hepatitis B was calculated based on the result of field survey as well as through data-base of the Second National Health Services Survey of MOH in 1998. The cost-benefit analysis was employed, in which the saving of the financial burden on hepatitis B patients attributing to unsafe injections was taken as the benefit of intervention and the increased expenditures of AD syringes as the costs.

RESULTSThe total financial disease burden of Hepatitis B in China in 2001 was between RMB 16.19 and 20.17 billion Yuan and the financial disease burden per patient was between RMB 1755.38 and 1409.64 Yuan. Study on the cost-benefit analysis in the replacement intervention program showed high financial feasibility. The Benefit-Cost Ratio (BCR) of the measure was between 32.46 and 97.39, which was bigger in rural areas than that in cities. The direct BCR was less than one when the price gap between ordinary syringe and AD exceeded RMB 0.24 Yuan.

CONCLUSIONThe intervention of safe injection practice through universal usage of AD to replace ordinary syringe seemed to be applicable due to its high potential economic benefits.
