Objective To study the detection rate of early esophageal carcinoma using magnifying endoscopy,and to evaluate the relationship between the imaging patterns of microvasculature change and his- tological diagnosis.Methods Two hundred and fourteen patients with esophageal mucosa roughness,ero- sion,plaque,abnormal color and indentation in conventional endoscopy and 16 healthy volunteers were en- rolled.The magnifying endoscopy images were graded as four patterns by intraepithelial papillary capillary loop(IPCL)changes after iodine dyeing.The biopsies underwent pathologic evaluation.The comparison be- tween the imaging patterns of endoscopy and histological diagnosiswas was evaluated.Results 80.4%(90/ 112)esophagitis was type 2,and 85.7%(12/14)early esophageal carcinoma was type 3 and type 4.The difference was significant between early esophageal carcinoma and normal mueosa(?~2=27.32,P

Objective The factors influencing the dose distribution of intracavitary brachytherapy for moderately advanced and advanced uterine cervical cancer was studied.Methods Ninty-five patients with cervical cancerⅡ～Ⅲb who received radical radiation therapy in our department from Aug,2004 to Nov,2005,were treated with after-loading brachytherapy using,first,the self-designed“Mutipurpose Hori- zontal Transit Table”(MPHTT) for locating and treatment before the intracavitaray brachytherapy proper. The deviation of isodose curve based on A-B reference system,and the dose of deviation was defined by measuring in a practical standard phantom.Results There were significant influence on the deviation of i- sodose curve in pathology and para-metrial infiltration of cervical cancer and operating skill,but negative to clinical stage.The degree of deviation of isodose curve could not be lowered with the increase in sessions of intracavitary brachytherapy.Conclusions It is necessary to perform the locating,by use of mphtt,before the proper brachytherapy for patients with cervical cancer,not only for the identification of the deviation of i- sodose curve,but also to provide the evidence for revising the plan for dose adjustment of conformal radiation therapy in the pelvic cavity.

Objective The aim of the study was to explore the difference between the expression of CDg7 in peripheral blood and bone marrow on acute myeloid leukemia (AML n=30). Methods A flow cytometric quantitative analysis of expression levels for CD87 was performed on fresh blast cells in peripheral blood and bone marrow from patients with acute myeloid leukaemia using CD87, monoclonal antibodies. Analysis the difference between the expression of CD87 using matched t -test. Results The values of CD87 expression in bone marrow of 14 M5 cases are from 9.47 %～80.32 %, and from 11.49 %～87.46 % in peripheral blood. The values of CD87, expression in bone marrow of 8 M4 cases are from 14.27 %～46.28 %,and from 14.79 %～47.19 % in peripheral blood. The values of CD87 expression in bone marrow of 6 M2 cases are from 4.67 %～34.26 %, and from 8.96 %～39.78 % in peripheral blood. The values of CDs, expression in bone marrow of 2 MI cases are from 3.56 %～7.69 %, and from 5.21 %～8.96 % in peripheral blood.The expression of CD87 in peripheral blood and bone marrow from patients with acute myeloid leukaemia had statistical difference (t =3.13, P<0.05). Conclusion The levels of CD87 expression had difference between peripheral blood and bone marrow. The level in peripheral blood was higher than bone marrow. So when we performed quantitative analysis of expression levels for CD87, peripheral blood instead of bone marrow was commended.

Objective To analyze the correlation between anterior circulation artery stenosis and lacune or lacunar infarct(LI) in elderly patients.Methods A retrospective analysis of data was performed in 111 patients with intracranial artery atherosclerosis,ischemic cerebral infarction or transient ischemic attack from January to December 2016 in our hospital.All the patients underwent non-contrast brain MRI or CT scan,as well as one-stop dynamic whole brain 4D CT angiography and CT perfusion scan(CTA-CTP/ perfusion).Imaging data were retrospectively analyzed.Intracranial 4D CTA was produced by using MIP and CPR post processing.The correlation of intracranial internal carotid artery(ICA)and middle cerebral artery (MCA)stenosis with lacunar infarct or lacune was analyzed by chi-square test using IBM SPSS Statistics 22.0 software.Results The average age of 111 patients was(68.4± 6.8)years.A total of 19 phases with 6080 images were obtained by one-stop scanning.The optimal phase of artery visualization was selected from 19 phases for evaluating artery stenosis.Intracranial ICA and/or MCA stenosis were revealed in 94 patients,including 73(65.8％)patients with LI or lacune and 21 patients(18.9％)without LI or lacune.17 patients without intracranial ICA or anterior circulation of MCA stenosis included 7 patients(6.3 ％)with LI or lacune and 10 patients(9.0％)without LI or lacune.Anterior circulation vessels stenosis was positively correlated with lacunar infarction or lacune(x2 =7.794,P=0.005).94 patients with anterior circulation vessels stenosis were further divided into 2 subgroups:unilateral and bilateral stenosis.39 cases showed unilateral vessels stenosis,including 25 cases (26.6 ％) with LI or lacunein,and 14 cases (14.9 ％) without LI or lacunein.And 55 cases showed bilateral vessel stenosis,including 48 cases (51.1％)with LI or lacune,and 7 case (7.4 ％) without LI or lacune.The risk for LI or lacunein was statistically higher in bilateral vessel stenosis than in unilateral vessel stenosis(x2 =7.061,P=0.008).Patients with anterior circulation vessels stenosis combined with LI or lacune were 73 cases,including 31 cases of grade Ⅰ,19 cases of grade Ⅱ,14 cases of grade Ⅲ,and 9 cases of grade Ⅳaccording to Trial criteria(NASCET)classification,with no significant difference between the different grades of anterior circulation vessels stenosis.Conclusions A correlation between ICA or MCA stenosis and lacunar infarction or lacune may exist.Risk for lacunar infarction or lacune is higher in patients with bilateral artery stenosis than in patients with unilateral artery stenosis.

Objective To investigate the effects of output power,action time and radiofrequency(RF) needle on the cool-tip radiofrequency ablation(RFA) by experimental tools and to determine the value of ultrasonography in size evaluation of RFA zone.Methods The cool-tip RFA to fresh calf liver were monitored by ultrasound.The experiments by single electrode needle were performed with different combination of output power (80 W,120 W) and time (5 min,8 min,10 min).The cluster needle was used for assessment at 5 min with different output power(80 W,120 W).After the end of trial,the longitudinal specimens were cut open.The view and size of the ablation zone were recorded with naked eyes.The pathological changes displayed by optical microscope were recorded as well.Results The measurement of ablation zone with naked eyes showed with the ablation zone expanded with time in 80 W-power cases,but the pace of expansion slowed down,but in 120 W-power cases,expansion of the ablation zone was not obvious; the ablation zone in 120 W-power was bigger than that in 80 W-power at 5 min,their difference decreased with time,and the ablation zones were similar at 10 min.The cluster needle can produce ablation zone with lesser aspect ratio than that of single electrode needle,consequently similar to circle.Ultrasonic measurement of the ablation zone had real discrepancy.Most of longitudinal diameters were greater than the real ones,while in large ablation lesions,vertical diameters were often less than the real ones.Under optical microscope,no change could be found in shape and structure of the cells in ablation zone.Conclusion The output power and performing time have impact on ablation.The high-power output increased heat production as well as reduction of heat conduction.Compared with single electrode needle,the cluster needle produced ablation zone closer to real hepatic tumor,thus has more reliable effect to small hepatocellular carcinoma with diameter around 2 cm.The ultrasond has a great significance in RFA guidance,but it could not accurately define the border of ablation zone.

Abstract?AlM:To analyze of the clinical features of acute retinal pigment epitheltis ( ARPE) .?METHODS: The clinical data of 36 ARPE patients ( 40 eyes) attending this center from January 2008 to January 2014 were reviewed retrospectively. Of them, 21 patients (58.3%) were male (male :female=1:0. 71). The mean age was 40. 92±7. 13 years old (range:17~60y). The mean best-corrected visual acuity (BCVA) was 0. 50±0. 26 with a range of 0. 3 ~ 1. 0. Thirty-two patients were unilateral cases. All the patients were examined for BCVA, funds photography, fluorescein fundus angiography ( FFA ) , optical coherence tomography ( OCT) . FFA was shown as three types: type ▏ to multiple black light or grape variety fluorescent spot; Type II for l lesions visible fluorescence leakage; Type Ⅲ lesions with choroid neovascularization ( CNV ) . OCT was the following three forms: multiple RPE lesions layer reflection intermittent, proliferation ( type ▏); pigment epithelial detachment with limitations neural epithelium ( typeII);types l and ll with CNV ( type Ⅲ) .?RESULTS: Ocular fundus showed that the lesions were multiple dark-gray spots with a dark circumscribed area at the macular or nearby in all 40 eyes. FFA showed:21 eyes were type ▏, 17 eyes were type II and 2 eyes were typeⅢ, BCVA between type ▏ and type II was statistically significant (P<0. 05), the same was between type 芋. BCVA between different cases in the same type and between type II, Ⅲ, was no statistical difference ( P>0. 05). OCT showed 21 eyes wwere type ▏, 17 eyes were type II and type Ⅲ 2 eyes. BCVA average between type▏ andIIwas statistically significant (P<0. 05). The mean BCVA was no statistically significant difference between type II and Ⅲ patients (P>0. 05).?CONCLUSlON:ARPE fundus demonstrated the multiple dark gray discrete lesions, the degree of visual impairment related with the presence of pigment epithelial barrier and lesion location. OCT and FFA characterized three types. FFA is shown asblack light orgrape variety fluorescent spot, and is the basis of diagnosis. OCT can display the lesions organization form of each layer clearly. lt plays a more and more important role in the diagnosis and differential diagnosis of ARPE.

Postoperative pancreatic leakage remains a persistent problem after pancreaticoduodenectomy.For patients with a soft and nonfibrotic pancreas,double binding continuous hemstitch suture is an optimal method for anastomosis.From January 2011 to June 2012,92 cases of periampullary carcinoma with a soft pancreas underwent pancreaticoduodenectomy,and then a modified technique of pancreaticogastrostomy was performed with 2 continuous hemstitch sutures placed in the mucosal and seromuscular layers of the posterior gastric wall,respectively.The median time for pancreaticogastrostomy was 12 minutes,and only 15 patients had postoperative complications.Two patients developed pancreatic leakage(1 grade A and 1 grade B)postoperatively.Pancreaticogastrostomy with double binding continuous hemstitch sutures is a simple and safe reconstruction procedure for patients with a soft and fragile pancreas who received pancreaticoduodenectomy.

Objective:To investigate the effect of dihydromyricetin (DMY) on LPS-induced septic shock in mice and the related underlying mechanism.Methods:The LPS-induced septic shock mice model was established after the mice were pre-treated by DMY for 7 days.The mortality rate was calculated at 24,48,72,96,120,144 and 168 h after the mice were intraperitoneal injected with LPS.For elucidation of underlying mechanism ,RAW246.7 were pre-incubated with DMY for 1 h,and then stimulated by LPS 100 ng/ml.Western blot was performed for determination of P-ERK,P-JNK and P-p38 expression.Immunohistochemistry was applied to explore c-Fos and c-Jun nucleus translocation.Results:DMY could significantly inhibit LPS-induced mice mortality.Inhibitory effect of DMY on the phosphorylation of JNK and p 38 contributed to the anti-inflammatory effect of DMY in vivo.Furthermore , DMY obviously prevented c-Fos and c-Jun nucleus translocation.Conclusion:The anti-inflammatory effect of DMY is attributed to the suppression on c-Fos and c-Jun nucleus translocation ,via inhibition of the phosphorylation of JNK and p 38.
