Objective:To evalute the role of antidepressants in the treatment of functional dyspepsia.Methods:Separated 50 functional dyspepsia(FD)patients into 2 groups by random.Then treated the antidepressant group antidepressants,while the antidyspepsia group was treated with drugs to cure primary digestive system disease by individual principle.And both groups were treated with supportive psychotherapy.The therapy continued for 8 weeks.Mental and symptoms state evaluation was done before and after treatment by Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale(SDS)and by symptoms.Results:There was significant difference in the scores of SAS and SDS between the FD groups and normal groups(P0.05).Conclusions:FD patients commonly have depression or anxiety.Antidepressants have good efficiency in treatment of FD patients who has emotional impediment both for improving somatic and psychological symptoms.

Objective:To study the changes of iNOS expression in periodontal tissues of rats with periodontitis in orthodontic tooth movement. Methods:48 SD rats at 10 weeks were divided randomly into two groups: periodontitis teeth group and normal teeth group. The maxillary first molar was pulled mesially both in the two groups. 4 rats were executed each time after activation of pull-spring 1, 2, 3, 7,14 and 21d both in two groups. iNOS immunohistochemistry staining were done to compare the expression variations. Results: There were significant differences between the two groups in 2,3, 7, 14 and 21 d. The periodontitis teeth group had stronger positive signals. Conclusion: Periodontitis will increase the expression of iNOS in the rats periodontal tissue during tooth movement, and influence the reconstruction of periodontium.

Objective To investigate the effects of arginine combined with leptin in treatment of rats with a-cute pancreatitis. Methods Sixty Wister rats were randomly divided into sham operation group (group A), acute pancreatitis group (group B),arginine group (group C),leptin group (group D),arginine plus leptin group (group E),with 12 rats in each group. Acute panereatitis model was developed by retrograde injection of 5% sodium tauro-cholate into cholangiopancreatography in rats. After 6 hours, medicine were given by intraperitoneal injection, ab-dominal aortic blood and pancreatic specimens were taken for measurement of tumor necrosis factor-α(TNF-α), ser-um amylase,nuclear factor-κB (NF-κB) activity of pancreatic tissue, and pathological damage score of pancreatic tissue. Results TNF-α,Amylase,NF-κB activity, pathologic scores were(1.206±0.446)μg/L, (1617.2±18.8) U/L,0.174±0.013,0.6±0. 2 in group A;(3.201±0.321) μg/L, (4643.8±303.4) U/L,0.397±0. 025,7.8±1.3 in group B;(1.845±0.404) μg/L,(3370.9±173.2)U/L,0.255±0.026,3.9±1.1 in group C;(1.996±0.374) μg/L, (3693.7±208.0)U/L,0.274±0.062,4.2±1.2 in group D;(1.440±0.287)μg/L, (2501.0±771.4)U/L,0.211±0.027,2.3±1.0 in group E. Compared with group A, the indicators were significantly in-creased in group B (P < 0.05). Compared with group B, these indicators were reduced in group C and D (P <0.05). There was no significant difference between group C and group D. These indicators in group E were signifi-cantly lower than those in group C and D (P < 0.05). NF-κB in pancreatic tissue were positively correlated with other indicators(P <0.01). Conclusions In treatment of acme pancreatitis in rats, arginine combined with leptin has idenditfied effect, and the effect of combination therapy is better than that of separate medicine.

Objective Establishing the drug?resistant Candida albicans disseminative infected mice model for new drug screening. Methods The disseminative infected mouse model was generated by intravenously injecting a clinical Drug?resistant Candida albicans strain ( CaR) to immunosuppressive ICR mice. The features of model was evaluated by clinical symptom, survival condition, fungal burden in tissue, histopathology, cytokines assay and medication. Results After infected with CaR (0 day), the death of mice started at the first day, though, compared to clinical drug sensitive strain ( CaS) infected group, the difference of mortality rate in 16?day observation period was not significant in two groups (CaR, 90?7%;CaS, 86?2%, P =0?158), mice in CaR group died faster than those in CaS group at the early stage;On the fourth day of infection, Candida albicans could be detected in the different tissues, and we found fungal burden in kidney and brain was a significant difference. The typical granuloma caused by fungal infection was the main histopathological feature observed in the kidney, brain and heart. Cytokines in renal tissue were detected by flow cytometry, The changes of IL?1α,IL?6,TNF?αand IFN?γin kidney were significant. Compared with CaS group, IL?1 and IFN?γ were significantly higher and TNF?αdecreased significantly in CaR group. The mice of groups CaR and CaS were treated with 10 mg/kg fluconazole, the mortality rates were 83?3% and 37?5%, which have a significant difference. Conclusions In this study, we successfully established a drug?resistant Candida albicans disseminative infected mice model which is potential tool for the development of new anti?infectious agent.

Objective To establish a Juema minipig model of myocardial infarction, to evaluate the clinical indi?ces in the model pigs, and to explore the relationship between gene expression and metabolic decompensation. Methods 13 male Juema minipigs were randomly divided into control (Sham, n=5), myocardial infarction (MI, n=5) and normal control (for evaluating the recovery condition after surgery, n=3) groups. In the MI group, the ligation was done at the left descending coronary artery around the 1/3 distance to heart apex. Four weeks after the surgery, the cardiac function and serum biochemistry was analyzed. The histological changes and gene expression profiles in the myocardium in the peri?infarct area were exanimated. Results Ultrasonic images showed that the infarction was formed, the ejection fraction and fraction shortening were significantly reduced in the MI group ( ~32% and ~40% less than those of the sham group). Histological examination showed that myocardial fibers at the peri?infarct area were broken, dissolved, and there was con?nective tissue hyperplasia with increased neutrophil and lymphocyte infiltration. Microarray analysis revealed that two myo?cardial remodeling and pathology mediating pathways, three inflammation?related pathways, and 8 metabolic pathways ( in?cluding fatty acid, amino acid, and glucose metabolic pathways) were significantly changed. Conclusions We have suc?cessfully established a Juema minipig model of myocardial infarction. The less branches of the left descending coronary ar?tery allow us to establish a stable model by surgery with comparable characteristics in the clinic indices. The results of this study provides useful reference characteristics of an animal model with characteristic changes in the peri?infarct area.

Purpose: Laparoscopy is being increasingly accepted for pancreaticoduodenectomy. Stapled anastomosis (SA) is used extensively to facilitate laparoscopic pancreaticoduodenectomy (LPD); however, the incidence of anastomotic bleeding after stapled gastrointestinal anastomosis is still high. Methods: One hundred and thirty-nine patients who underwent LPD using Whipple method were enrolled in our study. We performed the SA with our reinforced method (n = 68, R method) and without the method (n = 71, NR method). We compared the clinical characteristics and anastomosis methods of patients with or without gastrointestinal-anastomotic hemorrhage (GAH), and operative parameters were also compared between the anastomotic methods. Results: Of the 139 patients undergoing LPD, 15 of them developed GAH. The clinical characteristics of patients with or without GAH were not significantly different except in the anastomotic method (P < 0.001). In the univariate logistic regression analyses, only the anastomotic method was associated with GAH. Furthermore, patients with the NR method had significantly higher incidences of GAH (P < 0.001) and Clavien-Dindo grade ≥ III complications (P < 0.001). Conclusion Our retrospective analysis showed that the SA performed with reinforced method might be a reform of SA without the reinforcement, as indicated by the lower incidence of GAH. However, further research is necessary to evaluate the utility of this reinforced method.

Objective To investigate effects of goal-directed fluid therapy on inflammatory cytokines under combined anesthesia.Methods 60 patients undergoing colorectal cancer surgery,aged 60 to 85 years old,which were classified as American Society of Anesthesiology(ASA)classⅡ~Ⅲ,were randomly assigned to Goal-directed fluid therapy group(group G,n = 30)and central venous pressure liquid management group(group C,n = 30). Life sign and BIS indexes were collected at the time points,before surgery(T1),after the start of the operation (T2),one hour after surgery(T3),after the operation(T4).Hemodynamic indexes were recorded.Two milliliter blood sample were phlebotomized for evaluation of TNF-α and IL-6 from each patient at T1,T3,T4.The infusion volume, the amount of bleeding,the operation time,anal exhaust time,and length of postoperative hospital stay were recorded. Results Comparing information between the two groups,infusion volume and colloid had an obvious decrease than that of group C(P<0.05).SVV and CVP of group G were much stable than group C.The levels of TNF-α and IL-6 of group G were lower than those of group C(P<0.01).The length of anal exhaust time and post-operative hospital stay group G were faster than that of group C(P<0.01).Conclusions Goal-directed fluid ther-apy is superior on fluid administration. It can reduce the release of IL-6 and TNF-α. It is beneficial to elderly colorectal cancer patients with hypertension.

Objective: To summarize the incidence, clinical manifestations, diagnosis and treatment of basal cell nevus syndrome and to provide reference for clinical diagnosis and treatment. Methods : Retrospective analysis of 4 cases of basal cell nevus syndrome admitted to the General Hospital of PLA during January 2017 to January 2018 and recent cases reported in the literature. Results: In this study, 1 males and 3 females were included. The patients included a mother and her child. All 4 cases were surgically resected. Pathological reports included all keratocysts of the jaws. There has been no recurrence since follow-up. Through literature summarization and analysis, the clinical manifestations of this syndrome were found to be diverse. Typical clinical manifestations include multiple keratocysts of the jaws, multiple blepharospasms or cancers, deformities of the spine or ribs, increased brachial distance, eye diseases or special face intracranial calcification. Conclusion Basal cell nevus syndrome is an autosomal dominant genetic disorder. The clinical manifestations are diverse and the diagnosis is often overlooked. The incidence of cysts in the jaws is one of the important clinical manifestations of this syndrome. Early diagnosis and proper treatment improve patient survival and quality of life.
