Objective To evaluate the effect of endoluminal treatment for Budd Chiari syndrome (BCS) .Methods In 36 patients with BCS were treated by inferior vena cava(IVC) dilation and endoluminal stent placement guaded by ultrasonography, including self expanding mental Giaturco stent placement in 33 patients and pure dilation in 3 patients. Portosystemic shunts(PSSs) were followed in 13 patients with hepatic venous occlusion a week after the endoluminal treatment, including splenorenal(S R) shunts in 5 cases,and mesocaval (M C) shunts in 8 cases. Results After endoluminal procedures ,slight heart dysfunction appeared in 3 cases . After shunting ,acute pancreatitis occurred in 1 case, and upper gastrointestinal hemorrhage occurred and finally resulted in death in another case on the 10th day after PSS.All the 36 patients were followed up for 1 month to 8 years. Restenosis of the distal part of stent was found in 1 case 2 years after the operation,hepatic vein occlusion occurred in 1 case 1 year after the treament, hepatoma occurred in 1case 3 years after the treatment,and 1 patient died of C type hepatitis a year later; and 2 cases with infertility had babies 1 year later. All patients had no stent migration or occlusion of shunts .Conclusions Endoluminal therapy guarding by ultrsonography is a convenient, safe and effective method for Budd Chiari syndrome. For patients with hepatic venous occlusions, a portosystemic shunt is recommended.The above mentioned methods provide a feasible and effective means for some kinds of Budd Chiari syndrome.

Objective To investigate the relationship between the onset of lower extremity venous thrombotic disease and seasons.Methods A retrospective study was conducted, 300 patients with lower extremity venous thrombotic disease admitted to HandanCity Hospital of Traditional Chinese Medicine (TCM) from August 2012 to February 2014 were enrolled, the incidences and TCM syndromes of patients with lower extremity venous thrombotic disease in different seasons were observed, and the pathogenesis and relationships between the types of TCM syndrome and seasons were analyzed.Results There were 142 patients with lower extremity superficial thrombophlebitis, and 158 cases with lower extremity deep venous thrombosis, the incidence of lower extremity venous thrombotic disease in spring was significantly higher than that in summer and autumn [32.8% (86/262) vs. 21.3% (54/254), 18.4% (50/272), bothP < 0.01], but lower than that in winter [32.8% (86/262) vs. 37.2% (110/296)], the difference was not statistically significant (P > 0.01); while the incidence of lower extremity venous thrombotic disease in winter was significant higher than those in summer and autumn (allP < 0.01). The incidences of damp and heat downward flow type in autumn and summer were increased compared with those in winter and spring [55.6% (30/54), 60.0% (30/50) vs. 20.0% (22/110), 23.3% (20/86), allP < 0.01], while the incidences of lower extremity venous thrombotic disease with damp heat and stasis syndrome in winter and spring were increased compared with those in summer and autumn seasons [80.0% (88/110), 76.7% (66/86) vs. 44.4% (24/54), 40.0% (20/50)].Conclusions The incidence of lower extremity venous thrombotic disease is related to seasons, and the onset is high in winter and spring, damp heat and stasis syndrome being the main type; according to different seasons, clinical treatment can direct to different pathogenic factors to adopt different preventive measures interfering with the patient's constitution in order to eliminate or reduce the risk factors, achieving the effect of the disease prevention.

Choledochojejunostomy is a common surgical method for the treatment of organ diseases such as hepatobiliary, gastrointestinal and pancreatic diseases, but there are many complications related to the operation. Benign biliary-enteric anastomosis stricture (BBES) is the most common long-term complication after operation, which seriously affects the quality of life of patients. At present, bile duct reconstruction and endoscopic treatment are the main methods to deal with BBES, but there are some limitations. The new interventional therapy has the advantages of small trauma, good repeatability, high success rate and few complications. It has been applied in many medical centers. The main treatment methods include percutaneous transhepatic biliary balloon dilatation, percutaneous temporary stent placement, percutaneous transhepatic choledochoscopy, magnetic compression anastomosis and intrabiliary ablation. Up to now, there is no uniform standard for the choice of interventional therapy for BBES at home and abroad, so it is of great clinical significance to establish a standardized interventional therapy strategy.

Objective To investigate the radiation dose levels to the adults examined from diagnostic exposure in Beijing. Methods The radiation doses to the examined individuals were measured by using individual diagnostic radiology equipments in 30 random hospitals from a total of 10 districts and suburban areas, including 1 182 samples of X-ray photography,542 samples of mammography and 410 samples of CT examination. Results 2 134 samples were measured in this study. The dose ranges of X-ray photography, CR, and DR were 0?4 -24?1, 0?3 -13?9 and 0?1 -15?9 mGy, respectively. The average dose range of glandular breast was 0?3-5?4 mGy. In 410 CT samples the value of CTDIw , CTDIvol and DLP were 28?1 - 96?3 mGy, 7?0 - 23?4 mGy, and 162?2 - 898?1 mGy·cm, respectively. Conclusions Several dose levels from diagnostic examination were higher than guidance level for medical exposure in GB 18871-2002,which should be noted.

Objective To explore the changes of Beclin-1,P62/SQSTM1,microtubule-associated protein 1 light chain 3 (LC3)and unc-51 like autophagy activating kinase 1 (ULK-1)in the brains of the rats in the deve-lopmental stage with epilepsy. Methods Seventy-two male Sprague Dawley (SD)rats aged 21 days were randomly divided into the control group and the epilepsy group. The rats in 2 groups were randomly subdivided into 4 groups according to the time intervals (3 h,6 h,12 h and 48 h),respectively,with 9 rats in each group. The rats in the epilep-sy group were injected with kainic acid (12 mg/kg)to induce epilepsy,and the rats in the control group were injected with equal volume of saline. The rats in 2 groups were anaesthetized and sacrificed. Then,the brain tissues of the rats were quickly removed according to the time intervals. The brain damages were determined by adopting Nissl staining method. The apoptotic cells were detected by Terminal - deoxynucleoitidyl transferase mediated nick end labeling (TUNEL)assays. The expressions of Beclin-1,P62/SQSTM1,LC3 and ULK-1 mRNA levels in cortex were mea-sured by using real-time quantitative polymerase chain reaction (qPCR)analysis. Results Nissl staining indicated that many neurons were damaged performing vague outline,irregularly aligned,pyknotic nuclei and shrunken somata in the epilepsy 48 h group. In addition,there was a huge loss of neurons in cortex in the epilepsy 48 h group [(82 ± 8)num-bers],compared with the control group [(122 ± 8)numbers],and the difference was statistically significant (F＝3. 768, P＝0. 01). The apoptotic cells tremendously increased in the epilepsy 48 h group [(13 ± 7)numbers],compared with the control group [(2 ± 1)numbers]by TUNEL analysis,and the diffe-rence was statistically significant (t＝ -3. 821, P＝0. 003). qPCR showed the mRNA levels of Beclin-1,P62/SQSTM1,LC3 and ULK-1 were upregulated in the epi-lepsy 12 h group (1. 70 ± 0. 75,1. 75 ± 0. 77,1. 52 ± 0. 43,7. 48 ± 6. 12)and the epilepsy 48 h group (1. 63 ± 0. 43, 1. 48 ± 0. 74,1. 74 ± 0. 55,7. 69 ± 5. 65),compared with the control group (1. 00,1. 00,1. 00,1. 00),and the differences were statistically significant (F＝2. 820,3. 452,5. 811,5. 002,all P＜0. 05). Conclusion The autophagy activates be-fore apoptosis occurs,and autophagy-related genes probably are involved in epilepsy-induced brain damage.
