Objective To explore the clinical features,diagnosis and treatment of solid-pseudopapillary tumor(SPT)of pancreas.Methods The clinical data of 19 patients with SPT treated in 8 years were studied retrospectively,included 3 males and 16 females.Results The type of operation was decided by the size and location of tumor.Pancreatic leakage was a familiar complication,there were 9 cases.Patients were followed up from 3 to 70 months,and no recurrence or metastsis was found.Conclusion Pancreas SPT is a rare type neoplasm of pancreas.Pancreas SPT is affecting primarily young women,complete resection results in excellent prognosis.

Objective To research the method for constructing an ECG acquisition platform on Zigbee based network with multi-node. Methods The platform is based on an SOC Zigbee chip CC2430. Furthermore,the hardware design and software ECG sampling process is introduced respectively. Results As the Zigbee can support dynamic routing on the platform,we can get ECG data in abundance,and meanwhile,users get more room and freedom. Conclusion It's a right nice scheme for colleting ECG data.

AIM To study mechanism of endothelin (ET) on canine pulmonary veins. METHODS The isometric tension of pulmonary venous strips was recorded. RESULTS ET 3 and IRL1640 produced contraction in pulmonary venous strips. ET 3 induced contraction was markedly suppressed by BQ123 (P

BackgroundThere are a lot of studies about the wound healing charateristics of cornea after SBK with femtosecond laser.In our study,mechanical microkeratome was preferred for corneal flap.We observed the proliferation of keratocytes by investigating the myofibroblast ( MF) activity.Objective The study was to compare the morphologic and histological changes in the cornea after sub-Bowmans keratomileusis ( SBK) with photorefractive keratectomy ( PRK) and laser in situ keratomileusis ( LASIK)by investigating the express of transforming growth factor-β( TGF-β)and α-smooth muscle actin( α-SMA)and to investigate the wound healing characteristiCs of cornea after SBK.MethodsTwenty-seven adult New Zealand white rabbits were randomly assigned into group A,B and C.SBK waa performed on the right eyes of each rabbit in group A,LASIK for group B and PRK for group C.All the left eyes were used as the normal control group.Histological examinations by light microscopy were performed on day 7,1 months,3 months after surgery.The expression of α-SMA and TGF-β and the number of activated MF were assessed by immunohistochemiatry.ResultsIn SBK group,corneal epithelium cells proliferation around the wound was seen and the numbers of active fibroblasts were increased after surgery.The expression of α-SMA or TGF-β around the corneal flap and the corneal 8troma started at day 7 postoperatively and peaked at 1 months and decreaaed around the corneal flap and the corneal 8troma started at day 7 postoperatively and peaked at 1 months and decreaaed t3mnh.TFβep( SBK:t=2.226,2.158,2.330,P＜0.05;PRK:t=4.745,6.524,6.293,P＜O.05).The numbersof activ( SBK:t=2.226,2.158,2.330,P＜O.05;PRK:t=4.745,6.524,6.293,P＜0.05).The numbersof activatedMFs were different fromLASIKstatisticallytoobetweenSBKgroupandPRKgroup ( SBK:t =4.439.5.692,4.175,P＜0.05 ; PRK:t=6.330,6.723,5.267,P＜0.05 ).Theα-SMAand TCF-βexpressionsin SBKgroupwerelessthan PRK group but more thanLASIKgroup( TCF-β:t =4.691,5.527,t =4.399,P＜0.05 ; α-SMA:t =9.637.10.282,8.197,P＜0.05).The numhers of MFs in SBK group was less than PRK group before 3 months and were same at 3 months ( t =5.188,4.529,P＜0.05 ).Conclusions ComparedwithconventionalLASIK,SBKcanup-regulatethe expression of α-SMA.TGF-β,activated MFs in the corneal flap.which enhance corneal biomechanics and promote healing.However,most of the disadvantages caused by wound healing in SBK still remain compared to PRK.

OBJECTIVE:To investigate the preventive use of antibacterials in perioperative patients with cholecystitis.METHODS:The preventive use of antibacterials in 118 perioperative patients with cholecystitis was analyzed retrospectively.RESULTS:Of 118 cases,100% had received antibacterials,100% were irrational in medication duration(up to 10.75 days on average),69.49% had high starting point of drug application,and 62.71% were irrational in medication time.CONCLUSION:The phenomenon of irrational use of antibacterials in perioperative patients with cholecystitis is common and serious,and there are many problems remain to be tackled urgently.

Objective To explore the methods of breast tumor surgery information platform construction.Method To construct the information platform from target location,overall framework,function etc.Result The building of information platform provided a full range of care for breast cancer patients.Conclusion The construction of information platform can further improve the quality of nursing in breast cancer patients.

Objective To investigate the electromyographic(EMG)characteristics of sternocleidomastoid muscle in patients with motor neuron disease.Methods The clinical and EMG data of 461 patients of MND group and 349 of non-MND group were analyzed retrospectively.Results The abnormality rate of sternocleidomastoid EMG in MND group was 60.3%,much higher than that in non-MND group(4.6%)(P

Objective:According to the tumor of children psychology, explore a set of suitable for children accurate tumor radiotherapy positioning method, in order to improve the positioning accuracy, thus improve the tumor clinical cure rate.Methods: 1.Eliminate fear; 2.Adaptability training; 3.The methods of psychological suggestion. Evaluation method: take psychological induction of radiation induced by radiation therapy in children with and without taking mental children from the placement time, downtime in drug utilization rate, treatment rate and bit error rate comparison.Results: There is obvious difference between two groups (P<0.05).Conclusion: radiotherapy positioning of children with psychological intervention in the method, can improve the treatment of children's compliance.
