Objective To evaluate the therapeutic efficacy of agitating thrombolysis technique for Budd-Chiari syndrome complicated with inferior vena cava (IVC) fresh thrombus. Methods From August 2004 to March 2009, 5 patients of Budd-Chiari syndrome (four males and one female, aged 36-48 years) with IVC fresh thrombus were treated with agitating thrombolysis technique. After anpography of IVC the recanalization of IVC was performed, which was followed by agitating thrombolytic therapy. Finally,IVC was dilated with percutaneous transluminal balloon angioplasty. Clinical follow-up of IVC patency was conducted by color Doppler sonography. Results After agitating thrombolysis. The thrombi were completely disappeared in all 5 patients without single occurrence of pulmonary embolism. In all patients, IVC remained patency on color Doppler ultrasonograph after following up for a mean period of 23.8 months. Conclusion Agitating thrombolysis technique is a safe and effective treatment for Budd-Chiari syndrome complicated with IVC fresh thrombus.

OBJECTIVE:To observe the therapeutic effect of reptilase combined with omeprazole in treating severe cran?iocerebral injury complicated with upper gastrointestinal hemorrhage.METHODS:A total of178patients were randomly di?vided into2groups,treatment group were treated with reptilase in combination with omeprazole and control group received single omeprazole with3days.RESULTS:The effective rates in treatment group and control group were96.55%and84.62%,respectively,there was significant difference between2groups(P

Chyluria is characterized by the presence of chyle in the urine. The most common cause of non-parasitic chyluria is the upstream obstruction of the thoracic duct and reflux of the chyle into the renal collecting system. Traditional treatments include dietary modifications and surgery. The recently developed new interventional technique to treat chyluria. Here, we firstly reported one case of chyluria caused by thoracic duct obstruction in China, which was successful treated with intranodal lymphangiography combined by percutaneous balloon plasty. The symptoms of chyluria were completely relieved after our operation, which provides a minimally invasive, safe and effective method for patients with ineffective chyluria after conservative treatment or surgery.

Objective:To explore the application of pyrophosphorolysis-activated polymerization(PAP)to monitor plasma cfDNA in ad-vanced non-small cell lung cancer(NSCLC).Methods:A total of 85 patients diagnosed with advanced NSCLC between March 2016 and June 2017 were enrolled in the present study. EGFR mutations in cfDNA extracted from the plasma were detected using PAP and ARMS-PCR technology.The concordance analysis of EGFR mutations involved plasma vs.tumor tissue and PAP vs.ARMS-PCR.Further-more,38 EGFR-positive patients were selected to monitor EGFR mutations with PAP.Results:No statistical differences in EGFR muta-tions were observed between plasma and tumor tissue(P=0.092),as well as PAP and ARMS-PCR(P=0.210).The detection rate of EGFR mutations in cfDNA was higher in the progressor than in the non-progressor(62.5% vs.21.3%,P<0.001).Conclusions:PAP can be used for detecting and monitoring EGFR mutations in cfDNA to predict disease progression.

Objective:To evaluate the feasibility, safety, treatment outcome, and the individualized surgical procedure selection of the interventional treatments of chylous leakage.Methods:From July 2019 to January 2022, the clinical data of 60 consecutive patients with chylous leakage underwent interventional treatment were respectively analyzed. The cases included chylothorax ( n=37), chylous ascites ( n=10), chyluria ( n=4), chylothorax combined with chylous ascites ( n=5), chylothorax combined with chylopericardium ( n=2), and pelvic chylous effusion ( n=2). Conservative treatment was considered to have failed for all patients. The lymphangiography was firstly performed to detect chylous leakage, then an individualized procedure was selected according to the lymphangiography results. The treatment outcomes and complications were recorded, and follow-up was performed. Results:Lymphangiography was technically successful in 55 of 60 patients (91.7%), and no cisterna chyli and thoracic duct opacification was observed in 5 patients. The procedures for the patients included lymphangiography alone ( n=23), thoracic duct embolization ( n=23), thoracic duct disruption ( n=5), lymphatic embolization for pelvic chylous effusion ( n=4), and balloon plasty for thoracic duct ( n=5). Clinical success was achieved in 53 of 60 cases (88.3%). The complication rate was 8.3% (5/60), and all complications were minor. The median follow-up time was 11 months (range 0.5-30 months) for 56 patients, and 4 patients were lost to follow-up. There was one patient presenting the reoccurrence of symptom, and 8 patients died. Conclusions:The interventional treatment of chylous leakage is safe with good outcomes and low complication rate. Individualized treatment procedures based on the lymphangiography findings is feasible and with good curative effect.

ObjectiveTo observe the therapeutic effect of Yiyuan Qiwei pills （YYQW） on diabetes mellitus-induced induced erectile dysfunction （DMED） in rats and explore its regulation on the nitric oxide （NO）-cyclic guanosine monophosphate （cGMP） signaling pathway. MethodFifty-five healthy SD male rats of clean grade aged 2-3 months underwent intraperitoneal injection of streptozotocin （STZ） to induce the DMED model， and another 10 healthy SD male rats of clean grade aged 2-3 months were assigned to the control group. The model rats were randomly divided into a model group， a sildenafil group （5 mg·kg^-1， ig）， and low-， medium-， and high-dose YYQW groups （1.5， 3.0， 6.0 g·kg^-1， ig）. The rats in the model group and the control group were given normal saline by gavage at 10 mL·kg^-1， once a day for two months. After intervention， the penile erectile function of rats in each group was measured by a pressure detection system. The pathological changes and ultrastructure of penile corpus cavernosum were observed by hematoxylin-eosin （HE） staining and transmission electron microscopy， respectively. The level of NO in the corpus cavernosum was detected by nitrate reductase. Enzyme-linked immunosorbent assay （ELISA） was used to detect the levels of cGMP and advanced glycation end products （AGEs）. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of endothelial nitric oxide synthase （eNOS）， neurogenic nitric oxide synthase （nNOS）， total nitric oxide synthase （NOS）， and phosphodiesterase type5 （PDE5） in rat penile tissues. The expression of above proteins was detected by Western blot. ResultCompared with the control group， the model group showed decreased intracavernous pressure （ICP）， NO， and cGMP levels， reduced mRNA and protein expression of nNOS and NOS， and increased PDE5 mRNA and protein expression （P<0.05）. Compared with the model group， the sildenafil group and the YYQW groups displayed increased ICP， NO， and cGMP levels， elevated mRNA and protein expression levels of nNOS and NOS， and reduced PDE5 mRNA and protein expression levels （P<0.05）. There were no pathological changes in the tissues and cell ultrastructure of the corpus cavernosum in the control group， while serious pathological changes were observed in the model group. Additionally， the sildenafil group and the YYQW groups were superior to the model group， the optimal effect was observed in the high-dose YYQW group. ConclusionYYQW can improve the penile erectile function of DMED rats and reduce the pathological damage of corpus cavernosum. The mechanism may be related to the promotion of nNOS and NOS expression， the inhibition of PDE5 expression， and the activation of the NO/cGMP signaling pathway.
