Objective To observe the curative effects of treatment with Edaravone for acute massive cerebral infarction.Methods 48 patients with acute massive cerebral infarction were randomized into the treatment with Edaravone group(Edaravone group,24 patients) and the conventional treatment control group(control group,24 patients).Two groups patients were admitted conventional treatment for cerebral infarction.Edaravone group patients were admitted with Edaravone 30 mg into 100 ml saline infusion introvenously,twice a day,linked 20 ～ 25 d.Respectively before and after the treatment,neurologic function dificit score(NDS),plasma fibrinogen(Fib) content,coagulation blood function,activity of superoxide dismutase(SOD) were examined.The clinical efficacy was compared between the two groups.Results NDS of tow groups after treatment were significantly lower than those of before treatment,activity of SOD were significantly increased than those before treatment(all P0.05).Significant efficiency ratio of the Edaravone group(87.5%) was significantly higher than that of the control group(45.8%)(P

Objective To understand the intestinal nervous system(ENS) pathological change in rats with acute renal failure(ENS).Methods Rat acute renal failure model was established,the intracanthus blood was drew to determine the serum total creatinine(Scr) blood urea nitrogen(BUN) after 48h and 4th-day,then the rats was sacrificed at fourth day each rat's kidney tissue,duodenum,jejunum,ileum,colon and rectum were stained with hematoxylineosin(SE).Finaly, iNOS staining by immunohitochemstry,observed the numbers of the ENS nerve plexus, ENS nerve cell , and iNOS positive cell nerve plexus. Check whether there has hyperemia hydrops, degenerative necrosis, and inflammatory cell infiltration on the mucosa epithelium.Results ⑴Kidney histological change was occurred. The kidney tubules degenerative necrosis was found in all the ten cases of kidney failure, and the hyaline cast, mesenchyme hemorrhagic necrosis, and inflammatory cell infltration were seen. ⑵ HE coloration and microscope inspection;numbers of the ENS nerve plexus and nerve cell of the acute kidney failure group were less than the normal group, especially in the ileum and rectum .⑶The number of the iNOS positive cell nerve plexus in ENS of the rats with acute renal failure was apparently less than that of the normal group. In addition, the iNOS positive presentation was stronger than that of the normal group.Conclusions The findings suggest that toxic metabolites of uremic rat acts on the ENS,and thus leading to pathological changes of ENS,resulting in stomach and intestinal mortor function disorder.

Objective To study on the efficacy and safety of treating achalasia by gastroscopic balloon dilation under anesthesia. Methods Fifteen patients with achalasia were given intravenous propofol and midazolam before dilation. Patient's feeling or distress and operative duration were recorded. The changes of blood pressure (BP) , heart rate ( HR) and blood oxygen saturation ( SpO2 ) were also recorded and analyzed. Results Patients did not complain of any discomfort or pain during gastroscopy. The time of recovery from anesthesia was 17 -27(23. 2) minutes. There were significant changes in clinical scores before and after dilation ( P

Objective To investigate the gastric empty and electrogastrogram(EGG) in patients with renal insufficiency before and after hemodialysis, and to study the enteric nervous system (ENS) in experimental acute renal failure rats.Methods The comparisons of gastric emptying and EGG before and after hemodialysis were carried out in 15 patients with uremia who have gastrointerstinal symptoms. Acute renal failure models were also established. The neuroplexus of ENS and levels of some gut hormones were investigated. Results The EGG and gastric emptying were abnormal in patients with uremia before hemodialysis, but improved after dialysis. The neuroplexus of ENS with positive nitric oxide synthase(NOS) staining in rats with acute renal failure was significantly decreased. The levels of gastrin, vasoactive intestinal peptide and motilin in rats with acute renal failure were (159.1?55.6)?g/L, (121.6?48.9)pg/L, and (6.32?3.55)pmol/L, respectively, which were significantly different from those of the control group(P

Objective To observe the characteristic of precancerous lesions and early gastric carcinoma with narrow belt imaging technology. Methods The 74 patients were enrolled in this study. The same case was used as self-control. The operation was made in pain-less under anesthesia. When the mirror was advanced to the duodenal descending segment, an ordinary microscope mode was used and the mirror was back to Mallory, the lesions found were recorded, the image was zoomed in with low-fold and observed (1.4,1.6,1.8 times). Suspicious lesions were collected and biopsies were made. Results Chronic gastritis could be commonly found in type A and AB. Mild in-testinalization and mild atypical hyperplasia could be commonly found in mixed type holding type C, type BC and AB. Moderate atypical hy-perplasia could be found in type CD and AC, and heavy atypical hyperplasia in type CD and D. Early gastric cancers (superficial depressed) were seen in type BC and irregular thick type A. Advanced gastric cancers were in type CD, D and C. Helicobacter pylori infection were common in type A and B. Protruded type, sunken type were not easily missed with common endoscopic and NBI. But "for ordinary focus of infection, it was easily missed with common endoscopic, while less with NBI. Conclusion NBI is a simple and safe method, which can be used to find precancerous lesions and early gastric cancer lesions more easily. It will enlaance the diagnosis rate of precancerous lesions and early gastric cancer as positive rate of biopsy was markedly improved.

This study was aimed to explore the effect of total flavonoids and saponins from Huang-Qi Ge-Gen (HQGG) decoction on blood glucose (BG), serum lipid, interleukin-12 (IL-12) and interleukin-15 (IL-15) of liver in diabetes mellitus (DM) rats, in order to investigate their interactions in regulating DM processes. A total of 66 SD rats were randomly divided into 6 groups, which were the normal group, model group (A1B1), control group, total flavonoids group (A2B1), total saponins group (A1B2), and total flavonoids and saponins group (A2B2), with 11 rats in each group. Except the normal group, other groups were intraperitoneal injected with streptozotocin (STZ). And the experiment was according to 2×2 factorial design experiment scheme. The BG was determined before STZ injection and 7 days after the STZ injection. After 30 days, BG, serum lipid, IL-12 and IL-15 of liver were tested. Related indexes were calculated to the weighted composite score. Main and interactive effect of total flavonoids and saponins were studied according to the factorial design experiment scheme. The results showed that compared with the normal group, all indexes of model group showed statistical differences (P<0.05). Total flavonoids and saponins from HQGG decoction can effectively reduce BG, without any interactions between them. Both the total flavonoids and total saponins can reduce serum cholesterol (CHO), triglyceride (TG), liver IL-12 and IL-15. And there were interactive effects. The single use of herb achieved better effects than the combination. It was concluded that total flavonoids and saponins from HQGG decoction can reduce BG, CHO, TG, and liver IL-12 and IL-15 levels in rats. However, the regulation of total flavonoids and saponins on indexes mentioned above showed no additive effect.

Objective: To explore the relationship between platelet counts at admission and in-hospital mortality in patients with type A acute aortic dissection (AAD). Methods: We investigated 183 consecutive patients with CT conifrmed diagnosis of type A AAD treated in our hospital from 2012-02 to 2013-05. There were 126 (68.9%) male and the patients were divided into 3 sets of groups.①In-hospital surviving group,n=157 and In-hospital death group,n=26.②According to platelet counts, the patients were divided into 5 groups: Q1 group, platelet counts ≤ 119×109/L,n=36, Q2 group, platelet (120-149) ×109/L,n=37, Q3 group, platelet (150-173)×109/L, n=36, Q4 group, platelet (174-228)×109/L,n=37, Q5 group, platelet >228×109/L,n=37.③At admission, platelet ≤ 119×109/L,n=36 and platelet >119×109/L,n=147. In addition, the patients were further divided into another 4 groups based on operative condition: platelet ≤ 119×109/L with operation,n=18, without operation,n=18; platelet > 119×109/L with operation,n=96, without operation,n=51. The basic information at admission including platelet counts, WBC and D-dimer were studied in all groups, the primary endpoint was in-hospital mortality. Results: The overall in-hospital mortality was 14.3%. Compared with In-hospital surviving group, the In-hospital mortality group had decreased platelet counts, lower blood pressure and higher level of D-dimer. The mortality in Q1 group (38.9%) was higher than those in Q2, Q3, Q4 and Q5 groups (10.8%, 11.1%, 8.1% and 2.7%), allP<0.001. The risk of death in Q5 group was higher than Q1 group (HR=11.2, 95% CI 2.13-123.3,P=0.007). With adjusted age, gender and other relevant factors, when platelet counts ≤ 119×109/L, the risk of in-hospital mortality with Cox multivariate model I analysis was (HR3.90, 95% CI 1.67-9.09,P=0.002), with Cox model II was (HR=2.67, 95% CI 1.15 -6.19,P=0.023). Conclusion: AAD patients with admission platelet counts ≤ 119×109/L had the high risk of in-hospital death, even with operation, lower platelet counts was still related to in-hospital death.

Objective To investigate the place reaction of support drainage tube in cholecystojejunostomy and its pathological changes.Methods Eight pigs were randomized into 2 groups.The tube-placing cholecystojeunostomy(n=2)or choledochocholedochostomy(n=2)and non-tube-placing cholecystojejunostomy(n=2)or choledochocholedochostomy(n=2)were performed respectively.All the 8 pigs were sarcrificed 3 months after the operation for pathological examination.Results Gross anatomy catheter group showed anastomotic inflammatory hyperplasia, wall hardening hyperplasia,luminal narrow contracture and stone formation.Microscopic biopsy showed bile duct mucosa in interstitial lymphocytes, plasma cells and other chronic inflammatory cell infiltration, a large number of fibrous tissue hyperplasia.However, these features were not found in pigs without placing the tube.Conclusion The tube can not prevent the stenosis.It might promote the formation of stricture since it can stimulate inflammatory hyperplasia and tissue hardening.

Objective To study the feasibility and effect of scarless endoscopic thyroidectomy(SET) and minimally invasive video-assisted surgery of the thyroid(MIVA) endoscopic technique. Methods SET: Incisions were made on the anterior part of the breast and mareolata,blunt dissection of the subcataneous planes of the neck and chest were administered .MIVA: Incisions were made 3cm above the thymus notch and the operation was video assisted in the thyroid adenoma extripation and subtotal thyroidectomy. The thyroid nodules were extirpated or subtotal thyroidectomy was performed. Results All 10 cases of the SET and 12 cases of the MIVA were successful performed and without complications. Conclusions For thyroid surgery,SET is a good cosmetic operation,MIVA is a minimal trauma and effective operation.

Objective To investigate the effect of absorbable hemostatic membrane on hemostasis in lum-bar surgery.Methods From 2014 to 2015 in our department,40 patients(mainly for lumbar spinal stenosis and lumbar spondylolisthesis patients)were enrolled in lumbar surgery(via transforaminal interbody fusion,TLIF), and were rando mLy divided into the absorbable hemostatic membrane group and the ordinary hemostasis group. The volume of 24-hour incision drainage and the hemoglobin of preoperative and 1 day postoperation were compared between the two groups. Results Compared with the control group,the volume of incision drainage and hemoglobin in the absorbable hemostatic membrane group were significantly decreased at 24 hours after surgery. Conclusions The hemostatic effect of absorbable hemostatic membrane is very good in lumbar surgery,absorb-able hemostatic membrane is worthy of application in spinal surgery.
