Various collateral circulations were detected by 2D color Doppler flow imaging(2DCDFI)in the part of 70 patients of liver cirrhosis with portal hypertension,including reopened umbilical veins,dilated focal intrahepatic veins,dilating,hepatofugal centrifugal hepatic blood flow in the portalveins,perisplenic and retroperitoneai varices etc.Red and blue blood flows were detected in the collateral circulations by 2D-CDFI and appeared as continuous venous spectrum with low velocity blood volume could be calculated to evaluat the therapeulic effectiveness of portal-systemic shunt operation.

Objective To assess the effect of arterial embolization in treating hyperthroidism by colour ultrasonography.Methods Forty two cases of hyperthyroidism were treated with thyroid arteries embolization. A few days before and 1, 3, 6 months after embolization, the echograms of thyroids were observed including the volumes of thyroids and the internal diameters of thyroid arteries were measured with colour ultrasonography respectively. The Vs, Vd, Vm, PI, RI were measured with the Doppler and the quantities of blood flow were calculated. The relationships of changes for all these parameters and T 3, T 4 and TSH were analysed. Results Before artery embolization all thyroids were enlarged with diffusely homogenous or heterogenous low echos and nodules in some patients accompanied by widenings of the thyroid arteries and their branches full of blood supply. The volume of thyroids decreased after artery embolization. 1 3 months later the echo of thyroids enhanced and got coarse with decrease of the thyroid vasculature and narrowing of vessel calibers except a few star or spot like blood streams were sometimes seen within the thyroids and no blood flow signals found in some cases. 3 6 months after embolization, the echo of thyroids decreased gradually or unevenly distribnted. All the parameters of blood flow before and after the treatment showed statistically significant differences( P

Objective To investigate the effect of parecoxib on cardiac function after acute myocardial infarction (AMI) in rats. Methods Twenty-four adult male SD rats, weighing 230-250 g, were randomly divided into 3 groups ( n = 8 each): group Ⅰ sham operation (group S), group Ⅱ AMI and group Ⅲ parecoxib (group P). Myocardial infarction was induced by ligation of left anterior descending branch (LAD) of coronary artery in group Ⅱ and Ⅲ . In group S, LAD and cervical sympathetic trunk were exposed but not ligated and transected.Group P received intrperitoneal parecoxib 8 mg/kg once a day for 3 days 24 h after ligation of LAD, while group AMI received normal saline instead. At 4th day after ligation LAD, the left ventricular systolic pressure ( LVSP),left ventricular end-diastolic pressure (LVEDP) and ± dp/dtmax were measured and recorded. Blood samples were taken from common carotid artery to determine the plasma concentrations of TXA2 and PGI2 and PGI2/TXA2 was calculated. Then the animals were sacrificed and hearts removed. Myocardial infarct size of left venicle was calculated. Results Compared with group S, LVSP, ± dp/dtmax, plasma concentrations of PGI2 and PGI2/TXA2 were significantly decreased, while LVEDP and plasma concentrations of TXA2 increased in group AMI and P( P ＜0.05). Compared with group AMI, LVSP, ± dp/dtmax, plasma concentrations of PGI2 and PGI2/TXA2 were significantly decreased, while LVEDP and plasma concentrations of TXA2 increased in group P ( P ＜ 0.05). There was no significant difference in myocardial infarct size between group AMI and P (P ＞ 0.05). Conclusion Parecoxib can improve cardiac function after AMI in rats and the mechanism is related to regulation of the balance of PGI2/TXA2.

Objective:To observe the therapeutic effect ofcapsaicin at different concentrations on chronic knee arthritis pain model in mice.Methods:Choosing 50 healthy adult male Kunming mice builded chronic knee arthritis pain model by injecting 0.01 mL CFA (Complete Freund's Adjuvant,CFA) into left joint cavity.The model would be succeed in building after 3 weeks.The successful model mice were divided into five groups randomly (n=10):The first experimental group (saline group),the second experimental group (capsaicin excipient group),the third experimental group (0.5 ％ of capsaicin),the fourth experimental group (3 ％ of capsaicin) and the fifth experimental group (8 ％ of capsaicin).All of the mice would be observed the time of withdrawal latencies from the thermal heated surface after administration of one,four and seven hours,and thermal withdrawal time within 60 days after the injection.Results:①The physiological saline group compared with excipient group,the thermal withdrawal time had no statistically significant difference (P＞0.05)after administration of one,four and seven hours,and thermal withdrawal time within 60 days.②The acute pain duration of the third group would disappear after capsaicin injection 7 hours,four hours for the fourth group,and one hour for the fifth group.③The duration of analgesia of the third group,lasted for 18.9± 1.1 days;The analgesia time of the fourth group lasted for 33.7± 1.0 days;The analgesia time of the fifth group lasted for 58.2± 1.2 days.Conclusions:Capsaicin has analgesic effects on chronic knee pain model in mice induced by CFA,and the days of analgesia increases with the concentration of capsaicin.

Objective To observe the efficacy of ginger-partitioned moxibustion plus Chinese medication enema in treating diarrhea caused by antibiotics. Method Forty patients with antibiotics-induced diarrhea were randomized into an observation group and a control group. Twenty cases in the control group were treated by Metronidazole and Live Combined Bifidobacterium and Lactobacillus tablets; twenty cases in the observation group were given ginger-partitioned moxibustion plus Chinese medication enema.

Objective To investigate the feasibility of combined laparoscopic and thoracoscopic esophagectomy for esophageal carcinoma and gastro-esophageal anastomosis in right thoracic cavity.Methods We retrospectively analyzed the clinical data of 38 patients who underwent esophagectomy for esophageal carcinoma and gastro-esophageal anastomosis in right thoracic cavity from October 2011 to August 2012.To remove the stomach in laparoscopic and the esophagus in thoracoscopy.The main portion of a gastric conduit is created using three to four firings of a linear stapler(Ethicon Endo-surgery,Cincinati,OH) and jejunum stoma.Gastric conduit was pulled into the chest cavity and anastomosed to the esophagus.Results The average operative time was 280 minutes,the mean operative blood loss was 120 ml.No patient required laparotomy.No pulmonary complications or anastomotic leaks occurred.One had gastric retention,another one had chylous hydrothorax.All patients were cured,no one dead in hospital.Conclusion Combined laparoscopic and thoracoscopic esophagectomy for esophageal carcinoma and gastro-esophageal anastomosis in right thoracic cavity is technically feasible and safe,minimized trauma,less operative blood loss and quick recovery.

ObjectiveTo assess the differences of short- and long-term postintervention status on ocular and systemic symptoms for patients with ocular myasthenia gravis (OMG) after pyridostigmine bromide, corticosteroid, thymectomy, or thymectomy-corticosteroid combination therapy ( combination ).MethodsThis retrospective plus prospective study included 180 OMG patients, whose age of onset ≥ 15 years, treated non-randomly with above therapies separately: thymectomy group (60 cases ), corticosteroid group (39 cases), combination group ( 31 cases ), symptomatic group ( 50 cases ). Postintervention status complying with Myasthenia Gravis Foundation of America (MGFA)complete stable remission ,pharmacologic remission, or minimal manifestations was considered as desirable response, which was used as statistical indicator. Results ①Corticosteroid group showed higher desirable response rates on ptosis, ophthalmoplegia and general weakness at 3-6 months after treatment than other groups, and 42. 1％( 16/38 ) of them at 3 months achieved the desired state of ptosis, higher than the symptomatic group (7/48,14. 6％, ×2 = 8. 200, P = 0. 004 ). ② Ascending ideal rates had been presented in both combination and thymectomy groups since 1 year after treatments, while a little bit higher rate was presented in the former. At the end of observation, 21.7％ ( 13/60 )of patients in thymectomy group achieved complete stable remission.By paired longitudinal comparisons,thymectomy group showed higher ideal rates on ptosis (22/40,55.0％ ), ophthalmoplegia ( 16/27,59. 3％ ) and general weakness (20/40,50. 0％ ) at 2 years than that at 3 months( 11/59,18.6％ ;11/44,25.0％ ;9/60,15.0％ ;P =0. 002, 0. 031,0.000). ③For those patients by symptomatic treatment, the average age of onset was (51.9 ± 18.0) years, higher than that by other 3 therapies (F = 10. 563 ,P =0. 000). ④OMG patients with ophthalmoplegia more likely select corticosteroid or combined therapy. Ophthalmoplegia in combination group was higher than that in symptomatic and surgery groups( ×2 = 12. 939,14. 380, P =0. 000 in both). Ophthalmoplegia in corticosteroid group was higher than that in surgery group ( ×2 = 8. 017, P = 0. 005 ).Conclusions Corticosteroid appears to early overcome ptosis, ocular motor dysfunction and general weakness for patient with OMG in early-to-middle adulthood.Thymectomy andsurgery-corticosteroid combinationtherapies bothshowlong-term effectonthem.
