Objective To analyze the characteristics of military training injury caused by distal femoral fractures that used reverse interlocking intramedullary nail(retrograte nails) and condylar plate to fix,and then compare the clinical treatment effects.Methods Retrospective analysis of clinical information of 30 cases,14 cases were treated with reverse interlocking intramedullary nail(reverse nail group) and 16 cases with condyle plate fixation(condyle plate group),all the cases were followed up for 12～20 months to compare the treatment effect and complications.Results According to Merchan criteria with clinical evaluation of knee function,the rate of good and excellent was 85.7% in the reverse interlocking in-tramedullary nail group,68.7%(P

A 35-year-old woman patient,complained of intermittent pain in the left flank for a week.Abdominal ultrasound and computed tomography scan revealed a left renal mass.Nephrectomy was performed,and a final diagnosis of adult Wilms' tumor was made based on histopathology and immunohistology.Chemotherapy was conducted for 4 times with dactinomycin D,vincristine and doxorubicin after surgery.At the time of the last recheck,the patient was alive with no evidence of disease.Adult Wilms' tumor is the exceptional malignant renal tumor.Only 1%-2% of Wilms' tumor is diagnosed in adult patients.Because of unspecific tumor symptoms in adults,the diagnosis is frequently made by histology.The diagnosis of adult Wilms' tumor is difficult to make preoperatively because diagnostic imaging only confirms the presence of a renal mass.Stage and histology are the clinical factors guiding the selection of postsurgical treatment and prognosis.Having retrospected 6 cases of adult Wilms' tumor between 1950 and 2007 and reviewed related reports,we conclude that the proper strategies of adjuvant treatment as applied to childhood Wilms' tumor patients after surgery can conspicuously improve the outcome in adult patients.

objective To determine a proper fiducial photography distance setting for ideal amptitied endoscopic imaging of parathyroid gland by high definition endoscopy system.Methods 30 patients were operated with MIVAT mode (modified Miccoli's approach) for treatment of thyroid carcinoma from Apr.2013 to Mar.2014.High definition imaging was established by Image 1 Endoscopy System(Karl Storz Co.) to observe parathyroid gland and related fine anatomical structures during surgery.5 fiducial photography distances (1.0/1.5/2.0/2.5/3.0 cm) were separately tested during surgery.Maximally amplified parathyroid gland images of each setting were obtained by the approaching-amplifying photographic method,and then the size of the real parathyroid glands as well as their screen images were measured and recorded to calculate the magnification.A proper fiducial photography distance setting was determined postoperatively by comparison of the magnification times,as well as clarity,stability of the imaging and surgical maneuverability.Results ①90 parathyroid glands were successfully observed and measured.②At the longest fiducial photography distance (3.0 cm),the parathyroid gland could be stably magnified by 14.26±3.06(long trail)/12.62±2.88 (wide trail)times,but their contour and color not clear.③At the intermediate distance (2.5 cm),the parathyroid gland could be magnified by 16.74±3.15 (long trail)/14.81± 3.47(wide trail)times with the graphics stable,and the color and contour more clear,but the vascular pedicle and the tiny vessels under the capsule still blurred.④At the shortest distance (1.0 cm),the parathyroid gland could be magnified by 27.72±6.45 (long trail)/26.33±7.22(wide trail)times,not only the color and contour,but also the vascular pedicle and the tiny vessels under the capsule of the gland became further clearer,unfortunately the graphics was shimmy and unstable.Conclusions ①2.5 cm can be a proper fiducial photography distance for searching,identifying and preserving parathyroid gland in MIVAT,while 1.0 cm can be a special fiducial photography distance for further confirming parathyroid gland when necessary.② Current high definition endoscopy system can be applied to identify the parathyroid gland if fiducial photography distance was properly set and approachingamplifying photographic method was used.Along with the magnification of the imaging,the features of the parathyroid gland may become clearer,including its yellow-brown color and oval contour,as well as the detail structures such as the tiny vessels under the capsule and the vascular pedicle.

Objective To investigate the effects of peroral catheter balloon dilatation on patients with dysphagia caused by cricopharyngeal achalasia after stroke.Methods Thirty-two stroke survivors with cricopharyngeal achalasia were randomly divided into a control group and a treatment group,each of 16.Both groups were given routine dysphagia rehabilitation training,but the treatment group was additionally given peroral balloon dilatation therapy six times a week for 2 weeks.Both groups were given swallowing function evaluations and videofluoroscopic swallowing examinations (VFSS) before and after the treatment.Results After the treatment,14 of the 16 patients in the treatment group demonstrated improved swallowing,significantly better than the control group,where only 9 patients had improved.The VFSS showed dysphagia to have been relieved in both groups,but significantly more in the treatment group.Transit duration in the pharnx was significantly shortened from 0.28 s to 0.16 s in the treatment group,but no significant difference was tound in the control group.Conclusion Peroral catheter balloon dilatation is effective for relieving cricopharyngeal achalasia after stroke.

AIM: To study the effects of ischemia/reperfusion (I/R) on primary cultured sinoatrial node (SAN) cells and the influence of pinacidil (a K_(ATP) channel activator). METHODS: The SAN cells were isolated from newborn rats and purified. The 48 h cultured cells were cultivated in following mediums: simulated reperfusion solution as normal control, simulated ischemia/reperfusion solution (I/R), Pinacidil+I/R (P+I/R), 5-HD+P+I/R and 5-HD+I/R. Spontaneous action potentials were recorded by ruptured-patch whole-cell technique in current clamp ((I=0)) and the maximum diastolic potential (MDP), upstroke velocity (UV), action potential overshoot (APO), interbeat interval (IBI) and action potential durations at 50% repolarization (APD_(50)) were measured. RESULTS: Compared with control group, simulated ischemia/reperfusion shorten APD_(50), reduced UV, MDP and APO. Exposed to pinacidil, MDP of cells in I/R groups was hyperpolarized; IBI, UV and APO were increased; APD_(50) was shorten. 5-HD couldn't block the effects of pinacdil on APD_(50), IBI and MDP, but reversed its actions on increasing UV and APO. CONCLUSIONS: Pinacidil made changes of AP in I/R group by opening different K_(ATP) channels of SAN cells. The role of this changes on protection in SAN cells during ischemia/reperfusion requires further investigation. [

Objective:To prepare sirolimus ( SRL) dropping pills to improve SRL solubility and dissolution. Methods:The base of SRL dropping pills was screened. The optimal formula and preparation process were also optimized by orthogonal design. The equi-librium solubility, hygroscopicity and drug release in vitro of SRL dropping pills were studied. Results: PEG6000 was chosen as the base. The optimal preparation conditions of SRL dropping pills were as follows: the ratio of SRL and base was 1∶10, the dropping speed was 65 drops/min, the dropping temperature was 95℃ and the temperature of cooling solvent was 5℃. The equilibrium solubili-ty of SRL dropping pills in different solvents was increased significantly compared with that of SRL. The hygroscopicity of the dropping pills was notable. The drug release in vitro of SRL dropping pills was similar to that of the marketed tablets with quick and complete re-lease. Conclusion:SRL dropping pills exhibit increased solubility and improved dissolution, which are valuable to be studied further.

Objective To study the diagnosis and management of extra-adrenal pheochromocytoma.Methods A retrospective clinical study was done on 33 patients of extra-adrenal pheochromocytoma treated at our department.Results Extra-adrenal pheochromocytoma accounted for 16.2％ (33/204) of all pheochromocytoma patients admitted between Jan 2005 and Dec 2012.There were 13 males and 20 females.The mean age at diagnosis was 45 years,with a range from 17 to 81 years.14 patients were hospitalized for abdominal discomfort,8 patients suffered from typical hypertension symptoms including headache and dizziness and blurred vision,one of bladder pheochromocytoma was found paroxysmal hypertension and 10 patients had no obvious clinical symptoms.All the patients underwent CT scan,and 8 extra-adrenal pheochromocytoma were discovered.11 patients were given circulation expansion therapy.Most of the tumors were located at bladder(3 case),renal hilus (7 case) and para-aorta(23 case).There were two patients with multiple tumors.In 26 cases,blood pressure fluctuated when touching tumor during operation.All the patients were treated with surgical operation.Except for 1 biopsy,32 patients underwent total resection of tumor including a case combined resection with left kidney and a case with the spleen.There were no perioperative mortality.Postoperative follow up showed very good prognosis,with no death.Conclusions Compared with imaging examination,clinical manifestations and laboratory tests were less evaluable for the diagnosis of extra-adrenal pheochromocytoma.Proper preoperative preparation and precise operation is essential for the prognosis.
