Objective To investigate the efficacy of endoscopic intranasal structure reconstruction surgery for rhinogenous headache. Methods 82 cases of rhinogenous headache were given endoscopic intranasal structure reconstruction. Compared VAS scores before and 6 months after treatment, counted the effective rate. Results Among the 82 patients, 69 patients(84. 1%) were cured, 8 cases (9. 8%) were of obvious effect, 5 cases (6. 1%) were invalid, and the total efficiency was 93. 9%. VAS scores of the mucosal contact headache group before treatment were greater than that of the sinus headache group (P<0. 05). Compared with VAS scores before treatment, both of the two groups had lower VAS scores after treatment (P<0. 05), but there was no significant difference between the two groups after treat-ment (P>0. 05). Conclusion Endoscopic surgical operation can remove the extrusion of the nasal cavity and paranasal sinuses and factors of nasal congestion, and then reconstruct normal anatomical structure of nasal cavity, thus restoring normal function of paranasal sinuses. It has good therapeutic effect on rhinogenic headache.

Objective To investigate the usefulness of acoustic radiation force impulse (ARFI) elastography for noninvasive evaluation of liver fibrosis in rats.Methods A total of 70 male Wistar rats were included in the group for dimethylnitrosamine (DMN)-induced liver injury,and 10 saline-injected rats were used as normal control.Hepatic injury was induced by a single intraperitoneal injection of DMN at a dose of 50 mg/kg of body weight.Several rats in the group with DNM injected and the normal control group were randomly selected and sacrificed at each of the following post-injection time:day 5,7,10,14,21,24,and 28.And their livers were taken for pathology analysis.All the rats underwent ARFI elastography before sacrificed in order to acquire a shear wave velocity (Vs) to represent liver stiffness.Correlation between Vs and the histological finding was analysed.ResultsAmong 58 successfully modeled rats,9,13,14 and 12 rats were found to be with S1,S2,S3 and S4 of liver fibrosis pathologically,respectively.And 10 rats were found to be with severe inflammatory activity without any fibrosis.Values of Vs increased with the stage of liver fibrosis ( P ＜0.05).There was a significant correlation between Vs and stage of liver fibrosis ( r =0.947,P =0.000).The areas under ROC curve for the diagnosis of fibrosis S≥S1,S≥S2,S≥S3 and S=S4 were 0.983,0.995,0.999 and 0.964,respectively;for the cutoff values of Vs were 1.59 m/s,2.13 m/s,2.33 m/s and 2.51 m/s,respectively,the sensitivity was 95.8％,92.3％,100％ and 84.6％,and specificity was 100％,100％,96.9％ and 95.6％,respectively.The values of Vs in the group with severe inflammatory activity were significantly higher than those in the control group ( P =0.000).ConclusionsARFI has a relatively high value in the evaluation of liver fibrfosis in rats,while severe inflammatory activity may affect its accuracy.

Objective To investigate the clinical characteristics and related pathogenetic factors in Takayasu arteritis with myocardial involvement.Methods We retrospectively analyzed clinical data of Takayasu arteritis patients with myocardial involvement of Peking Union Medical College Hospital from 1987 to 2013.Results Myocardial involvement was diagnosed in 23 patients from 86 Takayasu arteritis patients.Sixty-five percent (15/23) of patients presented with congestive heart failure.Fifteen patients were without coronary artery involvement.Sixty-five percent (15/23) of patients with mild to moderate hypertension.Seventyfour percent(17/23) patients had pulmonary hypertension.Left ventricular ejection fraction was (34.70 ±0.09)％.Glucocorticco costeroid and immunosuppressive therapy could significantly increase left ventricular ejection fraction (t=4.302,P＜0.05).Conclusion We emphasize that myocardial involvement is common in Takayasu arteritis.It is an independent risk factor that impacts the prognosis.Early detection of myocardial involvement and effective therapy can improve the prognosis.

Objective To investigate the clinicopathologic features of intestinal polypoid lymphoma (PL) in children. Methods The clinicopathologic data of 15 cases of pediatric intestinal PL in Jiangxi Provincial Children 's Hospital were retrospectively analyzed. Immuohistochemistry was used to detect the expressions of CD10, bcl-6, bcl-2, MUMl and ERCC1, then EB virus (EBV)-encoded RNA (EBER) status was tested by using in situ hybridization. Results Amongst 15 cases studied, 13 cases were Burkitt lymphoma (BL), 1 case was diffuse large B-cell lymphoma (DLBCL) and 1 case was between DLBCL and BL (DLBCL/BL). The positive rate of CD10, bcl-6, bcl-2, MUMl, ERCC1 and EBER were 100.0%(13/13), 92.3%(12/13), 0, 7.7 % (1/13), 15.4 % (2/13), 53.8 % (7/13), respectively in 13 BL cases. The clinical stage of 13 patients with BL: 11 cases (84.6 %) Ⅱ stage, 1 case (7.7 %) Ⅲ stage, 1 case (7.7 %) Ⅳstage. The clinical stage of DLBCL and BL/DLBCL: Ⅱstage. 14 cases of PL had survival time without tumors, 24-120 months follow-up, and 1 BL patient inⅣstage without chemotherapy died after 2 months. Conclusion BL is a major subtype of intestinal PL in children, which shows a low clinical stage and a good prognosis.

Objective To explore the feasibility of electromagnetic navigation for hepatic ducts exploration by choledochoscope based on a three-dimensional (3D) printing model.Methods The retrospective descriptive study was conducted.The clinical data of 1 patient with obstructive jaundice combined with secondary biliary tract dilation who was admitted to the Beijing Tsinghua Changgung Hospital in April 2016 were collected.Digital imaging and standardized format data of enhanced computed tomography (CT) scan were collected,3D reconstruction of liver and bile duct were done under a 3D printing model,and then a hollow model of bile duct was achieved.Choledochoscope with internal electromagnetic probe was inserted into the printed hepatic ducts.Four points of anatomical markers in left and right hepatic ducts and common hepatic duct were chosen as fiducial markers for calibration and registration.Results After registration,the scope can be tracked in main hepatic segmental bile ducts.The locations of choledochoscope matched precisely the navigation results.Conclusion Electromagnetic navigation may bring accurate tracking effectiveness for choledochoscopic examination.

Objective To analyze the specimen types,ward distribution and risk factors for infections caused by extended-spectrum β-lactamase(ESBLs)-producing-Escherichia coli(ECO) in recent two years,so as to provide bacteriological basis for both hospital infection control and clinical anti-infection treatment.Methods Non-repetitive 443 ECO strains isolated from the hospitalized patients in the Third People′s Hospital of Shenzhen were collcted,and the phoenix100 system was employed for bacterial identification and antimicrobial susceptibility tests.ESBLs-ECO was further confirmed by the double-disk synergy test,and the risk factors caused ESBLs-ECO were statistically analyzed.Results A total of 115 strains of ESBLs-ECO were identified among the 443 strains of ECO,which accounted for 26.0%.The ESBLs-ECO strains were mainly isolated from the sputum,urine,and blood specimens.Among the isolated ESBLs-ECO strains,20.9% were isolated from the department of Tuberculosis,13.9% from the department of pediatric,12.2% from the department of live disease,and 8.7% from the department of infection.The male sex,surgery and use of the third generation cephalosporins were independent risk factors of ESBLs-ECO infection.Conclusion The isolation rate of ESBLs-ECO in this hospital is high.It is necessary for the hospital to strengthen the control of nosocomial infections according to the risk factors.More attention should be payed on male patients,the standardization of surgical operation and disinfection,and the restriction of using the third generation cephalosporins,so as to reduce the incidene of ESBLs-ECO infections.

Objective To observe the effect of sitagliptin on carotid intima-media thickness (c-IMT) and serum hs-CRP and IL-6 levels in the patients with newly diagnosed type 2 diabetes mellitus. Methods 65 patients with newly diagnosed type 2 diabetes mellitus who were admitted to the outpatient clinic and were hospitalized in our hospital were selected. They were randomly divided into sitagliptin phosphate tablet group (experimental group) with 35 cases and metformin hydrochloride tablet group (control group) with 30 cases. All patients were given health education about diabetes, diet guidance and exercise. All patients were given drawing of venous blood at a fasting condition ≥10 h before treatment and 6 months after treatment to determine the following indicators: FPG, 2 hPG, hs-CRP, IL-6, TC, TG, HDL-c, LDL-c, HbA1 c, hs-CRP, IL-6, etc, and c-IMT was determined. Results There was no statistically significant difference in blood glucose, blood lipids, inflammation index and c-IMT between the two groups before treatment (P>0.05); after treatment, FPG, 2 hPG and HbA1 c were significantly lower than those before treatment in both groups, and the difference was statistically significant (P<0.01). There were statistically significant differences in FPG and HbA1 c between the two groups (P<0.01). There was no statistically significant difference in 2-hour postprandial blood glucose between groups (P>0.05). The c-IMT, hs-CRP and IL-6 levels in the experimental group after treatment were significantly lower than those before treatment, and the differences were statistically significant (P<0.05). There was no significant change in c-IMT in control group after treatment (P>0.05). hs-CRP and IL-6 had a decreasing trend compared with those before treatment, and the difference was not statistically significant (P>0.05). There were statistically significant differences in c-IMT, hs-CRP and IL-6 between the two groups after treatment (P<0.05). Spearman linear correlation analysis: c-IMT was positively correlated with hs-CRP levels and IL-6 (r=0.6585, P=0.000; r=0.571, P=0.000). There was no significant correlation between fasting blood glucose and glycosylated hemoglobin (P>0.05). Conclusion The DPP-4 inhibitor of sitagliptin has a clear hypoglycemic effect and can reduce c-IMT, hs-CRP and IL-6. The anti-inflammatory effects besides hypoglycemic effect may be involved in the reduction of atherosclerosis in the patients with diabetes mellitus.
