[Objective] To summarize the clinical experience on treating thoracic spinal little joints disorder by manipulation of embracing cervical and extracting chest. [Method] To col ect and analyze the theory and methodology of Pro.Fan's clinical treatment on thoracic spinal little joints disorder. [Result]Professor Fan has rich clinical experience for many years in the study and treatment of spinal diseases. He puts forward theories of“close relationship between symptoms with etiology”and“correct spinal little joints disorder”, that is to say, considering symptoms to detect it's etiology, thinking etiology to find out it's dislocation, the method of treatment is removing pathogeny, etiology is removed, symptoms are removed. Based on the theory, Pro.Fan invents the manipulation of “embracing cervical and extracting chest”to treat thoracic spinal little joints disorder.And this manipulation has significant effect on clinic. [Conclusion] Pro.Fan has great innovation on treatment of thoracic spinal little joints disorder and the manipulation of“embracing cervical and extracting chest”has significant effect on clinic.

Objective To summarize the experience in the diagnosis and treatment of intraductal papillary mucinous neoplasms (IPMN) of the pancreas.Methods The clinical data of 16 cases of intraductal papillary mucinous neoplasms of the pancreas in the First Affiliated Hospital of China Medical University from January,2000 to October,2013 was retrospectively analyzed.Results There were 9 males and 7 females,age ranging from 37 to 61 years (average 49 years).The common complaint was epigastric pain.Ultrasonography and CT scan found solid lesions in all cases,main pancreatic duct dilatation was found in 10 cases.All the cases received surgical resection of the tumor.Pathology showed adenomas in 14 cases,borderline tumors in one,and adenocarcinoma in one.14 patients were followed-up ranging from 5 to 48 months,all were alive without recurrence and metastasis.Conclusions IPMT is a special type of pancreatic tumor.Surgical resection is the most effective treatment with excellent prognosis.

Objective To compare the effects of oxygen therapy and local pressurization in alleviating plateau hypoxia at high altitude.Methods Forty-five healthy male soldiers were investigated at an altitude of 3992 meters.The subjects were randomly divided into three groups, ie.an oxygen inhalation group, a single-soldier oxygen increasing respirator (SOIR) group and a BiPAP group.The oxygen inhalation group was treated with oxygen inhalation via nasal catheter at 2 L/min.SOIR was used to assist breath in the SOIR group.The BiPAP group were treated with bi-level positive airway pressure ventilation, with IPAP of 10 cm H20 and EPAP of 4 cm H2O.PaO2、PaCO2、SpO2 and heart rate were measured before and 30 minutes after the treatment.Results There were continuous increase of PaO2 from (53.30±4.88) mm Hg to (58.58±5.05) mm Hg and (54.43±3.01) mm Hg to (91.36±10.99) mm Hg after BiPAP ventilation and oxygen inhalation, respectively (both P < 0.01).However, the PaO2、of the SOIR group was decreased from (56.00±5.75) mm Hg to (50.82±5.40) mm Hg (P < 0.05).In the other hand, the PaCO2、 was increased from (30.41±1.51) mm Hg to (32.5±2.98) mm Hg in the oxygen inhalation group (P< 0.05), declined from (28.74±2.91) mm Hg to (25.82±4.35) mm Hg in the BiPAP group (P < 0.05), and didn't change significantly from (28.65±2.78)mm Hg to (29.75±3.89) nun Hg in the SOIR group (P > 0.05).Conclusions Both BiPAP ventilation and oxygen inhalation can alleviate plateau hypoxia by improving PaO2 at 3992 meter altitude while SOIR has no significant effect.

Objective: To investigate the corrective effect of modified Brisson technique to treat concealed penis in children. Methods: From July 2015 to July 2017, 32 patients(3-10 years old, mean 7.2 years old )with concealed penis were treated with the modified Brisson technique in the Children′s Hospital of Zhengzhou University. All the children with concealed penis were treated by the modified Brisson technique, complications, postoperative results and followed-ups were retrospectively analyzed. Results: 32 cases of concealed penile children had pain on the postoperative day, 2 cases required patient controlled analgesia device. No infection and dehiscence were noticed after discharge. All the children were followed up for 6 months to 1 year, and the results were satisfactory. Review showed that the penile body was similar to the appearance after circumcision, with obvious extension exposure, normal exposure of penile scrotal Angle and penile pubic Angle, and no obvious retraction. The internal plate of the prepuce in 5 cases was slightly edema, and edema dissolved within 2 months. Conclusions Modified Brisson is a better method to treat concealed penis in children, which can correct the pathological structure and retain the integrity of penile skin to the greatest extent.
