OBJECTIVE: To evaluate the clinical effect of acellular dermal matrix (ADM) on the repair of different tissue defects in pharyngeal and laryngeal cancer. METHOD: Twenty-three cases of pharyngeal and laryngeal cancer were analyzed retrospectively, including 16 patients with pharyngeal cancer, and 7 patients with laryngeal cancer. After surgery, the patients appeared two types of tissue defects respectively: hypopharynx tissue defect and neck skin tissue defect. These defects were repaired with ADM, and the clinical effects were observed. RESULT: Sixteen cases of hypopharynx tissue defect and 7 cases of neck skin tissue defect were repaired with ADM. One case in hypopharynx tissue defect group and 2 cases in neck skin tissue defect group undergone pharyngeal fistula postoperatively. CONCLUSION The repair of tissue defects in pharyngeal and laryngeal cancer with ADM had some advantages, such as good histocompatibility, low immune rejection, wide material sources and simple method. There were some differences in clinical effects between hypopharynx cavity defect and neck skin tissue defects, so the emphasis of the need to pay attention to is different in the clinical.

OBJECTIVE: To compare the clinical results between stapled and traditional suture closure total laryngectomy. METHOD: Fifty-three cases of laryngeal cancer with total laryngectomy were divided into 2 groups: 32 cases with traditional suture closure total laryngectomy (group A) and 21 cases with stapled total laryngectomy group (group B). Compare two groups in pharyngeal fistula, postoperative bleeding, dysphagia, and nasal regurgitation. RESULT: There was no difference of postoperative pharyngeal fistula between group A and B (P>0. 05). The incidence of dysphagia, nasal regurgitation, and postoperative bleeding in group B were 23. 8%, 14. 3% and 14. 3% respectively, which were obviously higher than that in group A (P<0. 05). CONCLUSION Stapled total laryngectomy has the advantages of reducing the operative time and simplifying the operation with some disadvantages such as higher standards of operation indications, higher incidence of dysphagia, higher nasal regurgitation, higher postoperative bleeding, and poor medical economic profit. Traditional suture closure total laryngectomy is recommended in clinical practice.

Objective To investigate the incidence of the post-stroke emotion disorder, the relationship between post-stroke emotion disorder and the location of stroke, and the effects of Paroxetine combined with psychotherapy in treating post-stroke emotion disorder. Methods 181 patients with acute brain stroke were assessed by SDS and SAS. Of these patients, 54 patients met the criteria of depression and anxiety after acute brain stroke. These 54 patients were divided into 2 groups randomly. They were treated with routine anti-stroke medication, routine anti-stroke medication with Paroxetine combined with psychotherapy for 6 weeks, respectively. The rating scales such as SSS, HAMD, HAMA, TESS and so on were used to evaluate the improvement of symptoms and side effects. Results According to the evaluation of SDS or SAS, there were 81 patients (44.75%) with post-stroke emotion disorder. The rate of post-stroke depression with anxiety was 66.67%. Post-stroke depression with anxiety was related to the location of brain stroke, such as frontal cortex,left cerebral hemisphere and basal ganglia (P

An actinomycete strain P-13, with antimicrobial activity against muskmelon bacterial spot pathogens, was isolated from the muskmelon rhizosphere soil samples in Xinjiang. The strain P-13 was identified as Streptomyces rochei based on morphological, physiological characteristics and 16S rRNA sequence analysis. The agar diffusion bioassay showed that the diameter of inhibition zone against Acidovorax avenae subsp. citrull BFB and Pseudomonas syringae pv. Lachrymans P4 was above 19 mm and 17 mm, respectively. The antimicrobial substances obtained from strain P-13 were demonstrated to be alkaline and water-soluble compounds according to paper chromatogram analysis and exocellular metabolites. Furthermore, it was stable to be treated by 100?C for 10 min, pH 6 for 6 h, or ultraviolet treatment for 7 h. Moreover, it was insoluble in organic solvents, such as petroleum benzine, diethyl ether, and acetic ether.

Para-Hisian accessory pathway (AP) means the AP locate about 0. 5cm above or under the His bundle. To identify the AP location,the big tip catheter mapping must be under sinus rhythm,ventricular pacing and inducing SVT in order to avoid injury of His bundle. During ablation process, the surface morphology and juctional escape rhythm must be observed. If RF must be done under ventricular pacing, once ablating effect is confirmed,the pacing would be stopped and escape rhythm can be observed. If ante-grade condution are always through AP in SVT and endocardial mapping are confirmed multipe APs and AVN are bystander in SVT, we do not exclude abmormal growth in AVN. It can be ablated retrograde AP to treat SVT and should be avoided to ablate antigrade AP.

AIM To study the early cardioprotective effects of pharmacological preconditioning of nitroglycerin (NG) and buprenorphine (BU) used alone and in combination on myocardial ischemia in rats. METHODS Male Wistar rats were randomized to 5 groups. The ischemia and reperfusion injury was induced by ligation of the left arterior descending coronary arrery for 30 min and followed reperfusion for 2 h. The rats were subjected to different treatments before I/R. Normal saline (NS) was infused intravenously with the same volume of NG and BU in Sham group. Ischemia/preconditioning (IP) was performed by three cycles of 5 min I/R in EIP group. BU (1 0 mg?kg -1 ) and NG (0 3 mg?kg -1 ) was administered intravenously alone in BU and NG group or given together in B+N group to mimic the effects of IP, respectively. Heart rate, blood pressure, ST segment and arrhythmias were recorded continuously throughout the whole test. Plasma LDH and CK were measured on 30 min after ischemia and 2 h after reperfusion, HE and TTC staining were performed to determine myocardial necrosis at the end of test. RESULTS Compared with Sham group the onset of arrhythmias was delayed and the duration of ventricular premature contraction (VPC) was shortened remarkably ( P

96 anterior teeth with different degree of caries in 80 patients were randomly divided into 2 groups(n =48 teeth,40 patients). In the experimental group the teeth were repair with nanometer resin filling,in the control group with ceramic crown.In 0.5 to 1 year follow-up,the satisfaction rate and the clinical success rate were similar in the 2 groups(P >0.05).Application of nano resin aesthetic restoration can lower tooth injury,postoperative complications and the cost.

Objective To explore how the different intervention measures affect the outcome of central venous catheter-related thrombosis (CRT) in children. Methods A retrospective analysis was carried out to collect the clinical data of patients with CRT from the nursing management system of the Children′s Hospital Affiliated to Zhejiang University School of Medicine which reported by each nursing unit from January 1,2015 to December 31,2015. Results Totally 108 cases were included (72 boys and 36 girls), median age of 24.5 months (ranged from 1 month to 14 years old). Nearly 42.59% (46/108) patients suffered from neurological diseases. Nearly 55.56%(60/108) CRT was detected in the first week after catheterization. Once CRT conformed, there were four kinds clinical intervention options applied. Intervention 1: thrombolytic therapy with urokinase combined anticoagulation with nadroparin calcium. Intervention 2: anticoagulant therapy only. Intervention 3: thrombolytic therapy alone. Intervention 4: no medications. The differences of effective between the four kinds of intervention were statistically significant (χ2=13.380, P=0.004). The single-factor regression analysis was done to each relevant factor. Finally the multivariate regression analysis showed four factors had impacts upon the results. The factors were as follows:gender (OR=10.400, 95%CI 1.879-57.563, P=0.007);interval (OR=1.107, 95%CI 1.035-1.184, P = 0.003), size of thrombus(OR = 1.562,95%CI 1.033-2.362,P=0.035; Intervention 2 (OR =11.757, 95% CI 2.254- 61.327, P = 0.003), intervention 4 (OR = 35.397, 95% CI 3.493-358.760, P =0.003). Conclusions The earlier and small size thrombus is more soluble. Thrombolytic therapy or combined anticoagulation is more effective. It is recommended that if no contraindications presents, thrombolytic combined with anticoagulant therapy should start early standardized treatment.

Objective To investigate temperature changes in prefrontal cortex and hippocampus of heroin addicts with magnetic resonance spectroscopy (MRS).Methods 18 heroin addicts in the withdrawal state and 18 healthy volunteers (control group) were performed with MRS scan.First, resting-state MRS scan was performed on all subjects, and then did MRS scan again under visual stimulation while subjects were asked to carefully watch the heroin-related cue images.Measurements of NAA of the identified regions (the prefrontal cortex, bilateral hippocampus) were obtained from all subjects.Brain temperatures were calculated by the modified brain temperature-chemical shift equation.Results In resting state, the temperature of prefrontal cortex in heroin addicts group was higher than the control group, the difference was statistically significant (P<0.05),and the brain temperature was positively correlated with total dose of heroin (P<0.05).The prefrontal cortex/hippocampus temperature of heroin addicts group did not showed statistical significance between resting state and visual stimulation state (P>0.05).Conclusion MRS can be used to measure brain temperature noninvasively.Temperature change of brain may be helpful for exploring the mechanism of drug addiction and craving.

Objective To evaluate the expression and clinical significance of miRNA in plasma of patients with primary biliary cirrhosis.Methods Plasma from 19 PBC patients,10 healthy volunteers and 10 viral hepatitis patients were selected from Shanghai Songjiang Hospital from december 2010 to January 2013.Among them 3 PBC patients' plasma and 3 healthy volunteers' plasma were detected by miRNA microarray for miRNA expression profile examination.Real-time PCR was used to verify the results of microarray,miRNA target gene predictior software was used to predict the target genes of differentially expressed miRNA.ROC was used to determine the clinical value of plasma miRNA.Results According to microarray,a total of 16 miRNAs were found to be differentially expressed.As revealed by qRT-PCR,the expression of miRNA-92a-3p and miRNA-4516 decreased while the expression of miRNA-572 and miRNA-575 were up-regulated in PBC group compared with healthy controls (P ＜ 0.05).In comparison with nonPBC cirrhosis group,only miRNA-92a-3p and miRNA-4516 were down-regulated (P ＜ 0.05).The area under the curve (AUC)of miRNA-92a-3p for the diagnosis and differential diagnosis of PBC were 0.92 and 0.84,respectively.while for The area under the ROC curve of miRNA-4516,the AUC for diagnosis and differential diagnosis PBC were 0.89 and 0.76,respectively.The optimal cut-off values for identifying PBC from healthy controls were defined as 1.26 ng/μl.for miRNA-92a-3p (sensitivity,92％ ;specificity,80％)and 1.16ng/ul for miRNA-4516 (sensitivity,85％ ;specificity,70％)respectively.The optimal cut-off values for identifying PBC from viral hepatitis were defined as 1.08 ng/μl.for miRNA-92a-3p (sensitivity,89％ ; specificity,81％)and 1.06 ng/μl for miRNA-4516 (sensitivity,77％ ;specificity,68％).Conclusion The results indicate that plasma from patients with PBC has a unique miRNA exprssion profile and these differentially expressed miRNA can be used as clinical biomarkers of PBC.
