Objective To study the preventive effect of Omeprazole on post-endoscopic retrograde choledo-chopallcreatography(ERCP)-induced pancreatitis.Methods 126 patients were divided into two groups at random.One group received Omeprazole 20mg bid for two days.and the other group received placebo(Vitamine B).Blood was drawn in each group the day before,4 hours and 24 hours following ERCP for examination of amylase and hepa-torenal functions.Meanwhile Meanwhile the clinical manifestations of acute pancreatitis were also observed.Results Acute pancreatitis was clinically induced in 1.59% cases of placebo group,but none in the Omeprazole group.Hyperamy-lasemia occurred in 20.63%-7.93%in Omeprazole group at 4 hours and 24 hours after ERCP operation,while 30.16%.14.29%in placebo group;The incidence rate of acute pancreatitis following ERCP and hyperamylasemia 4 h after ERCP in omeprazole group were significantly lower than in placebo group(P<0.01,P<0.05).There were no significance differences in amylase 24 hours following ERCP between two groups(P>0.05).Concluslon Omeprazole can prevent the acute pancreatitis induced by ERCP to some extent.

Objective To study imageology anatomy concerned of sellar turica and explore its potential role on growth of pituitary adenomas. Methods According to classification of sinus sphenoidalis,103 normal imageology data of sellar turica region were analyzed, including 83 cases with entire saddle type sinus sphenoidalis and 20 cases anti-saddle type sinus sphenoidalis. Furthermore, the clinical data of 45 cases of pituitary adenomas with extension into sinus sphenoidalis were retrospectively studied. Results The relationship between sellar floor's shapes and sinus sphenoidals'types was that the larger the sinus sphenoidalis was, the deeper the floor was(98.8%). The relationship between sellar floor's shapes and the superior surface of hypophysis was that most of depressed sellar floors were companied with depressed superior surfaces of hypophysises(93.8%). The anteroposterior shapes of sellar turica in midsagittal can be divided into 4 types such as bag-type, kettle-type, tube-type, and sifter-type. 45 patients suffering from pituitary adenoms with extension into sinus sphenoidalis all had entire saddle type sinus sphenoidalis. Conclusions The imageology anatomy concerned of sellar turica could explain the phenomena of pituitary adenomas with extension toward sellar floor and sinus sphenoidalis. Referring to the literatures concerned, it indicated that the imageology anatomy was the key factor of affecting the growth of pituitary adenomas.

Objective To investigate the application of hypocaloric parenteral nutrition in postoperarive elderly patients with gastric cancer. Methods 59 elderly patients aged 60- 79 years with gastric cancer after operation were randomly assigned to receive 84 kJ · kg -1.d -1 hypocaloric parenteral nutrition (29 cases) and 126 kJ · kg-1 · d -1 standard-calorie parenteral nutrition (30cases),totally 6 d from postoperative 2 d. Complications, serum proteins, immune function,inflammation,blood glucose, liver function and recovery time of gastrointestinal function were observed during nutritional support. Results The postoperative complication rate were 37.9％(11/29) in hypocalorie group and 43.3 ％ (13/30) in standard calorie group ( P＞0.05),mainly pulmonary infection.There were no ditferences in levels of serum albumin,total protein and prealbumin between two groups at postoperative 3 d and 6 d (P＞0.05).Peripheral blood lymphocytes and T lymphocyte subsets CD3+,CD4+,CD4+/CD8- ratio were decreased after sugery,but CD8 1 values increased in two groups (P＞0.05).C reactive protein was increased significantly at postoperative 3 d compared with preoperation,and decreased at 6d than 3 d (P＞0.05).Blood glucose was decreased gradually at 3 and 6 d (P＞0.05).Postoperative liver function paraneters were elevated,no difference was found at 3 d (P＞0.05),and continued to rise at 6 d in standard calorie group than in hypocalorie group (P＜0.05). There was no difference in times of aerofluxus and cacation after operation between hypocalorie and standard calorie groups (P＞0.05). Conclusions Hypocaloric parenteral nutrition is a safe and effective method for nutrition support in postoperative elderly patients with gastric cancer.

Aim To investigate the protective effects of polysaccharides from the rhizomorph of Armillaria mella(AMP-1) on alloxan injured INS-1 cells.Methods Graded concentrations of AMP-1(2,10,50,100,500,1 000 mg?L-1) were added into the culture medium of alloxan injured INS-1 cells.The survival rate was measured by MTT assay.The amount of glucose-stimulated insulin secretion in different concentrations of AMP-1 was determined by radioimmunoassay(RIA).SOD and NOS activity,NO,MDA and GSH production were assayed colorimetrically.Results AMP-1 could reduce oxidative injuries induced by alloxan in INS-1 cells.The survival rate of cells treated with AMP-1 increased significantly.In the presence of 5.6 mmol?L-1 or 16.7 mmol?L-1 glucose,AMP-1(50,100,500,1 000 mg?L-1)increased glucose-induced insulin secretion in INS-1 cells in a dose-dependent manner.NOS levels and the production of NO and MDA decreased significantly by AMP-1,while SOD levels and the production of GSH increased.Conclusions AMP-1 promoted glucose-induced insulin secretion in INS-1 cells by increasing the abilities of scavenging the free radicals induced by alloxan.

Objective:To explore the prognostic factors of patients with Vibrio vulnificus sepsis. Methods:The clinical data of 67 patients with Vibrio vulnificus sepsis from January 2008 to December 2019 in the First Affiliated Hospital of Wenzhou Medical University were retrospectively analyzed. Univariate analysis was used to compare the differences in general information, clinical manifestations, admission laboratory indicators, antibiotics and surgery between the death group and the cured group. Then the factors with significant difference in univariate analysis were included in multivariate analysis, and the factors of prognosis were obtained. Results:Univariate analysis showed that there were significant difference in liver disease, admission with hypotension shock, multiple limb injuries; admission leukocytes, platelets, pH value, albumin, lactic acid, aspartate aminotransferase, creatinine, procalcitonin, creatine kinase, activated partial thromboplastin time, prothrombin time between the death group and the cured group (all P <0.05). Multivariate analysis showed that admission lactate ( OR=0.628, 95% CI: 0.461-0.855, P=0.003), albumin ( OR=1.330, 95% CI:1.062-1.667, P=0.013), creatine kinase ( OR=0.999, 95% CI: 0.998-1.000, P=0.016) and admission surgery time ( OR=0.118, 95% CI: 0.015-0.938, P=0.043) were risk factors of the prognosis. Patients with high lactate, creatine kinase and low albumin at admission indicate poor prognosis; patients with admission surgery time≤ 12 h have better prognosis. Conclusion:For the treatment of patients with Vibrio vulnificus sepsis, medical staff should dynamically evaluate these prognostic factors in the early stage, and early surgical treatment should be adopted to improve the prognosis of patients.

Objective To investigate the clinical manifestions, pathological features and diagnosing methods of Lafora disease. Methods The chnical and pathological features of 5 patients with Lafora disease who were diagnosed by axillary biopsies were systemically studied. The specimen were stained by HE, PAS and AB-PAS methods. Results Four of 5 cases had an onset during adolescence and 1 during adulthood. All cases presented with progressive generalized tonic-clonic seizure, myoclonus and dementia. Emotional disturbance, dysarthria and ataxia appeared in the early course of the disease. Lafora bodys were identified in myoepithelial cells and duct cells of both eccrine sweat glands and apecrine sweat glands in the biopsies of axillary skin. Conclusions Lafora disease could be confirmed by round and oval periodic acid-Schiff- positive inclusions in skin biopsy specimen combined with the proper clinical settings. Both axillary and other skins can be chosen as the sites of biopsy.

As the major member of serine/threonine protein ki-nases family, glycogen synthase kinase 3β ( GSK-3β) has well characterized roles in the development of a variety of diseases. However, it is noticed that modulation of GSK-3β in tumor pro-gress is two-faced. Once the activity of GSK-3βas a“pro-onco-genic factor” is inhibited, opposing role as a“tumor suppressor”can also be disrupted, which will trigger the consequent side effect on activation of Wnt/β-catenin signaling pathway. The is-sue has placed a major obstacle to anti-GSK-3β in cancer treat-ment. In fact, functional compartmentalization of a large number of intracellular signaling events cross-talked with GSK-3β can prevent their mutual interference and determine the cell fate. Therefore, understanding the specific mechanisms of GSK-3β in regulation of diverse signaling systems or refinement of a sub-strate competitive inhibitor may have great significance to exploit approaches selectively target GSK-3β in tumor treatment.

Objective To explore the effect and mechanism of superficial vein puncture for the first time in obese children auxiliary with venous enhancement.Methods From January 201 5 to July 201 5,1 20 children (3 -7 years old)with obesity were randomly divided into control group and observation group,60 cases in each group.The control group used conventional methods to select limbs superficial vein puncture,the observation group guided by visualizer to select limbs superficial vein puncture.Results The superficial vein puncture success rate of observation group was 96.67% for the first time,the puncture time was (78.95 ±6.68)s;Success rate of control group was 78.33%,the puncture time was (98.44 ±34.1 3)s,the differences between two groups were statistically significant (χ2 =1 0.385,t =21 .787,all P <0.05).Conclusion Obese children with venous visualizer superficial vein punc-ture success rate increased significantly,for the first time the puncture time shortened.

Objective: To explore the turnover and treament of postoperative remainder of giant nonfunctioning pituitary adenoma with suprasellar extension(SSE). Methods: The clinical data of 68 cases suffering from giant nonfunctioning pituitary adenoma with suprasellar extension(SSE)admitted into our department were retrospectively analyzed.These patients underwent primary transsphenoidal surgery. Results: Twenty cases had SSE adenomas totally removed(20.6%).In other 48 cases(79.34%)，SSE residues were shown in MRI recheck at one day after surgery.After 3 months，the 3rd MRI scanning was performed only to find that tumor residues descended to sellar floor in 21 cases,into intrasella in 8 cases，and down to the level of stalk hypophysial and the entrance to the sella in 3 cases.All of Patients with residual tumors received retranssphenoidal resection(the total removal rate of desending SSE residues was 96.9%).There were 2 cases with adenoma residues with slight descending.Obvious SSE adenomas were treated with transtranial approach.The twelve cases with small SSE residues were consecutively observed and two of them received gamma knife treatment because of unobvious postoperative visual improvement.The surgical mortality was 0%.There was no death during follow up in all of these patients.There were no cases with rhinorrhea.meningitis or visual deterioration.Two patients had supradiaphragmatic bleeding detected by routine postoperative CT. Conclusion: Staged surgery with two or multiple transsphenoidal resections is an appropriate treatment for giant nonfunctioning pituitary adenoma with supresellar extension(SSE)，with few complications.Futher study is warranted to investigate the growth pattern of pituitary adenoma.
