Objective To explore the application of high-frequency oscillatory ventilation(HFOV)postoperatively after open heart surgery in children with congenital heart disease.Methods From Jun.2007 to Jun.2008,a total of 1 957 cases were operated in pediatric center of Fuwai cardiovascular hospital.Thirteen cases of 1 957 were given HFOV.Among these 13 patients,8 were male and 5 were female;Age was(13.4?15.4)months.The range of weight was 4.2-12.5 kg.Four cases were tetralogy of Fallot,3 cases were transposition of the great arteries(1 case was corrective transposition of the great arteries),2 cases were total anomalous pulmonary venous connection,2 cases were total endocardial cushion defects,2 cases were pulmonary artery atresia,all patients were under cardiopulmonary bypass repaired operation except 1 patient with PAA under Blalock-Taussig procedure.All patients were mechanical ventilated after surgery.Results The duration of switching general mechanical ventilation to HFOV was(15.70?20.33)days and patients continued to be on HFOV about(10.0?7.5)days.In short term,the lung function of ventilation and gas exchange were be improved by HFOV,but the long-term result was not sa-tisfactory due to a high mortality.There were 5 survived(38.4%)in this group.Six cases of the patients succumbed to consolidation of lung.The commonest complication was pneumothorax(7 cases).Conclusions Short term of HFOV in children with congenital heart disease was satisfactory postoperatively.But there was a high mortality.HFOV can be regarded as a transition method for unsatisfactory long-term.

Objective:To investigate the feasibility and safety of a new method of natural orifice transluminal endoscopic surgery(NOTES) -totally transtracheal endoscopic thyroidectomy(TTET) .Methods:Three miniature swines and 6 beagle dogs were underwent TTET.Under general anesthesia,special designed endotracheal tube with 2-channel was used and endoscope and instruments were inserted through the respective channel.Incision of tracheal anterior wall was accomplished and partial or subtotal thyroidectomy was performed.Finally,the defects in the trachea were sutured with ENDO STITCH instrument.Results:Partial thyroidectomy was successfully accomplished on 3 pigs and subtotal thyroidectomy was done on 6 dogs.No serious complications such as anoxia,asphyxia,airway obstruction and death occurred during the operation.Animals were sacrificed 2h after the procedure and incision of trachea was found to be closely sutured.There were no subcutaneous emphysema and haematoma formation.Conclusion:Preliminary experimental results showed the feasibility and safety of TTET.Transtracheal access maintains the integrity of cervical tissues and achieves an optimal cosmetic outcome.TTET may open up a new field of NOTES on thyroid surgery.

BACKGROUNDCataracts is considered be formed because of an abnormal glucose metabolic pathway or oxidative stress. We explored the damaging role of ONOO- and antagonism of cholecystokinin octapeptide-8 (CCK-8) in diabetic cataractal rat lenses.

METHODSA diabetic cataractal animal model was established by peritoneal injection of streptozotocine (STZ). Thirty-six normal SD rats were taken as control group; seventy-two were given STZ (45 mg/kg) and then divided into STZ group and CCK-8 group (peritoneal injection CCK-8). STZ induced diabetic rats were treated with CCK-8 for 60 days. Lenses were examined with slit lamp at 20, 40 and 60 days. Immunofluorescent staining and Western blot analysis were used for determining nitrotyrosine (NT, a marker for ONOO-). PT-PCR and gene array analysis were used for determining the expression of inducible nitric oxide synthetase mRNA (iNOS mRNA) in lens epithelium (LEC).

RESULTSSTZ group rats developed lens opacity by 20 days that reached a high level by 60 days after STZ injection. CCK-8 group rats delayed the cataract formation. CCK-8 group rats delayed the cataract formation. There was no distinct expression of NT and iNOS mRNA in control group. In STZ group, there were distinct expression of NT and upregulation of iNOS mRNA; however, CCK-8 group showed weak expression of NT and downregulation of iNOS mRNA.

CONCLUSIONSNT, which may be a new form of oxidative stress, was expressed in diabetic rat LEC although CCK-8 could reverse NT damage in LEC. The results suggested that CCK-8 might be a useful therapeutic agent against diabetic cataract. The antagonizing mechanism of CCK-8 may be related to direct antagonism of ONOO- as well as its inhibition of the expression of iNOS mRNA for production of NO and therefore decrease in the formation of ONOO-.

Cancer has been increasingly recognized as a global issue. This is especially true in countries like China, where cancer incidence has increased likely because of changes in environment and lifestyle. However, cancer is not a modern disease; early cases have been recorded in ancient medical books in the West and in China. Here, we provide a brief history of cancer, focusing on cancer of the breast, and review the etymology of ai, the Chinese character for cancer. Notable findings from both Western and Chinese traditional medicine are presented to give an overview of the most important, early contributors to our evolving understanding of human breast cancer. We also discuss the earliest historical documents to record patients with breast cancer.

Objective To understand the status of depression and social support in cancer patients,to discuss the correlation between them,and to provide basis for improving their quality of life and mental states.Methods A questionnaire survey was conducted in 82 cancer patients with radiotherapy using Zung Depression Rating Scale (SDS) and Social Support Rating.Scale (SSRS).Results 50 cases (60.98％ ) had depression symptoms ; Their SSRS score was ( 44.51 ± 4.02),with significant difference from the norm (34.56 ± 3.73 ) scores (t =22.425 ;P ＜0.01 ).Significant differences of social support and depression were found among different age groups and educational levels of cancer patients (P ＜0.01 ).Depression of the patients had a significant negative correlation with the level of social support,objective support,subjective support and utilization of support (r =-0.791,-0.855,-0.710,and -0.658;P＜0.01).Conclusions Incidence of depression in cancer patients was high and the level of social support was fine.Depression is negatively related with social support.Nurses should pay attention to the role of social support systems in depression of cancer patients and use appropriate social support to improve the quality of life and psychological state of patients.

Objective To analyze the results of malaria focus investigation and disposal in Tengchong City,Yunnan Prov-ince between 2015 and 2016,so as to provide evidences for interrupting potential malaria transmission. Methods The malaria foci were investigated and disposed according to the malaria cases reported from"China Information System for Disease Control and Prevention"in Tengchong City between 2015 and 2016. The mosquitoes were captured by mosquito-lured lamp overnight to investigate the malaria vector in local. The peripheral blood samples were collected from the local residents with a febrile history in the foci within two weeks and the accompanists of the cases,and then the rapid malaria diagnosis tests were used to screen the malaria carriers. Results Totally 145 imported malaria cases were reported in Tengchong City between 2015 and 2016,and the focus investigation and disposal rate within 7 d was 100%(145/145). A total of 16186 mosquitoes of 12 species of Anopheles were captured,among which An. sinensis was the predominant,accounting for 64.31%(10410/16186),followed by An. kun-mingensis and An. minimus,with the constituent ratios of 14.15%(2291/16186)and 11.66%(1887/16186),respectively. One person(1.96%,1/51)in the 51 accompanists of the cases was positive in the malaria rapid diagnosis test. Conclusions The malaria transmission vectors such as An. sinensis,An. kunmingensis,An. minimus etc. are still distributed in Tengchong City,and An. sinensis is the predominant species. Therefore,the relevant authorities should continue to strengthen the focus in-vestigation and disposal to interrupt the potential introduced malaria transmission by imported cases in the future.
