Viral myocarditis (VMC) is a clinical frequent cardiovascular disease with extremely high mortality and disability rate ,which seriously impairs the health of children and young adults ,and its pathogenesis has not been fully elucidated .It is generally believed that VMC pathogenesis is mainly related to direct damage on myocardial cells ,immune damage ,cell apoptosis and cytokines .The present article made a summary about the research progress of its pathogenesis .

Objective To assess the efficacy of interventional bronchoscopic techniques used to treat stenosis of bronchial anastomosis after lung transplantation.Methods A retrospective study of 24 cases who underwent lung transplantation from September 2003 to August 2005 in our Unit was done. All recipients were subjected to surveillance bronchoscopy with biopsy at predetermined intervals and when clinically indicated. Endobronchial electrocauterization with microwave therapy apparatus and endobronchial electrocoagulation with high-frequency electrotome were performed for the management of bronchial stenosis or granuloma formation.Results There were 2 of 24 recipients (2/24,8.3 %) with stenosis of bronchial anastomosis. Airway stenosis appeared in 3 of 28 anastomoses (3/28,10.7 %): 2 on the left and 1 on the right. These patients with airway stenosis responded to interventional bronchoscopy,and their respiratory function was improved significantly.Conclusions Despite the improvements in surgical technique and immunosuppression strategies,a small number of patients still had airway complications after lung transplantation. Interventional bronchoscopic techniques,i.e. endobronchial electrocauterization with microwave therapy apparatus and endobronchial electrocoagulation with high-frequency electrotome will be effective in the treatment of airway complications after lung transplantation and with good response in respiratory function.

Objective To compare early enteral with parenteral nutrional support in patients after hepatectomy. Methods In this study, 59 patients were randomized into 2 groups to respectively receive enteral or parenteral nutritional support beginning the first day post-op for a week. The general nutrition condition, liver function, gut function, dosage of albumin, mortality, complication rate and expense were recorded. Results Patients were given same quantity of heat and nitrogen. At the end of the study, serum albumin, body weight and upper arm circumference had not reached the preoperative level in patients receiving enteral mutrition while all except for serum prealbumin had not reached the level in parenterally nutritional patients. Furthermore, the time of gut begins functional (29?12) h in enterally nutritional patients was shorter than in parenterally nutritional patients (38?14) h. Enteral nutrition was more economic than parenteral nutrition (P

ObjectiveTo study the water/fat ratio of patients with pancreatic ductal adenocarcinoma (PDAC) and mass-forming focal chronic pancreatitis (MFP),and to provided guide for the clinicians.MethodsThirteen patients with PDAC,8 patients with MFP and 20 healthy volunteers were scanned by GE 3.0T MR IDEAL sequence.The signal strength of outcome images was measured; the water/fat ratio analysis was performed.Two kinds of formula were applied,the first was WF1 =SW/SF,the second was WF2 =( SIP + SOP) / ( SIP - SOP).SW was the signal strength of water,SF was the signal strength of fat,and SIP was the signal strength of in-phase,while SOP was the signal strength of opposite phase.ResultsBy using the WF1 formula,the water/fat ratio of normal pancreas,PDAC,MFP was 7.97 ±0.95,9.94 ±1.19,5.08 ±0.49,respectively.By using the WF2 formula,the water/fat ratio of normal pancreas,PDAC,MFP was 11.51 ± 1.62,13.87 ±1.84,5.73 ±0.65,respectively.The difference among the three groups was statistically significant (P ＜ 0.05 ) under the same formula.The value of WF2 was higher than that of WF1,the difference in PDAC groups was also statistically significant ( P ＜0.05 ).ConclusionsThe water/fat ratio of pancreas among PDAC,MFP and normal pancreas is different.PDAC has the highest water/fat ratio,followed by the normal pancreas; MFP has the lowest ratio.

ObjectiveTo investigate the treatment effects of comprehensive nursing intervention on patients with chronic obstructive pulmonary disease(COPD) treated by non-invasive mechanical ventilation with BiPAP mode.Methods96 patients with diagnosed COPD and using non-invasive mechanical ven- tilation with BiPAP mode were randomly divided into the control group(46 cases) which was treated with routine measures and the comprehensive nursing intervention group (50 cases) which adopted comprehen- sive nursing intervention according to experimental design. The frightening degree, incidence rate of com- plications and clinical treatment effect by ventilator were compared between the two groups.ResultsPa- tients compliance with treatment and clinical treatment effect by ventilator in the comprehensive nursing in- tervention group was better than that of the control group. The frightening degree and incidence rate ofcomplications were lower than those of the control group (P < 0.01 ).ConclusionsComprehensive nurs-ing intervention with non-invasive mechanical ventilation with BiPAP mode can improve the treatmentcompliance of COPD patients,reduce complications followed by non-invasive mechanical ventilation andreach the prospective treatment effect.

Objective To analyze the expression and clinical significance of tumor suppressor phosphatase -tension protein gene(PTEN)in differentiated thyroid carcinoma and the relationship with the V600E gene site muta-tion of murine sarcoma viral oncogene homolog B1(BRAF).Methods The expression of PTEN was assayed by im-munohistochemical staining in differentiated thyroid carcinoma and adjacent tissues.The differences were compared between clinical pathological features.The BRAF V600E gene mutation was detected by fluorescence quantitative pol-ymerase chain reaction(PCR)and to investigate the correlation between the expression of PTEN and BRAF V600E mutation.Results The negative rate of PTEN was 78.75%(63 /80)in differentiated thyroid carcinoma,13.75%(11 /80)in adjacent tissues(χ2 =27.236,P =0.000).There were significant differences in the expression of PTEN between I -II and III -IV in TNMstage,grade I and II,and lymph node metastasis(χ2 =10.395,6.948,9.263,P =0.000,0.006,0.000).The differences were not significant in the expression of PTEN between different gender,≤45 years and >45 years different pathological types and tumor diameter <2cm and ≥2cm(χ2 =1.113,0.941, 2.301,1.567,P =0.185,0.213,0.087,0.181).There was correlation between the expression of PTEN and BRAF V600E mutations(r =0.301,P =0.004).Conclusion The expression of PTEN is involved in the occurrence and development of differentiated thyroid cancer and is associated with BRAF V600E.The PTEN has the predictive value of prognosis in tumors.

Objective To explore the application of non-breathholding photography technology in angiography. Methods 183 cases with abdominal and thoracic DSA examination were separated into non-breathholding experimental group and conventional breath-hold control group in proper order. The experimental group collected images in natural breathing and the conventional group gained images after inspiratory breathholding in imaging process. The images of two groups were adjusted by the post-processing functions and were print film; the quality of the images was evaluated. Results In the chest experimental group(n =37) had 36cases(97.30% )satisfactory and 1 case(2.70% ) unsatisfactory, and the control group(n=36)had 32cases(88.89%) satisfactory and 4 (11.11%) unsatisfactory. In the abdominal experimental group(n=55) had 53 cases(96.36%) satisfactory and 2 cases(3.64%) unsatisfactory images, and the control group(n=55) had 49 cases(89.09%) satisfactory and 6cases(10.91%) unsatisfactory images. There is no significant difference of the image quality between the two groups in each part (chest part ?2=2.02, 0.1
