Objective Objective To study the feasibility of direct applying MRI to TPS by measuring the geometric distortion of MRI. Methods Phantom 1 was made by marking radical arrangement of fat pipelines every 15? in foam phantom and Phantom 2 by net arrangement at every 2.7?cm. Coronal and transverse scan parallel with the radial and net fat pipeline in the phantom was performed at sequence of cranial FSE T2WI by Marconi 1.5T superconduct MRI machine. Geometric distortion in 5 different fields of view (FOV) was calculated by measuring the absolute borderline error of direct scan and coronal digital reconstructed radiograph (DRR). Results When FOV was equal or smaller than 11.0?cm?11.0?cm, 22.0?cm?22.0?cm and 27.5?cm?27.5?cm, the geometric distortion was 0.0, 1.1 and 1.4?mm of direct scanning MRI and 1.0,1.4 and 2.0?mm of coronal DRR. Conclusion When the magnetic field of MR is high and the tissue shows uniform density, MRI can be applied on TPS directly.

Objective To investigate the associated factors of complete virological response (CVR) in Entecavir treatment among chronic hepatitis B (CHB) patients with positive HBeAg.Methods Data of 166 CHB patients with positive HBeAg receiving Entecavir treatment in Yantai Infectious Diseases Hospital during December 2009 and May 2014 were collected.Clinical data including age,gender,genotype,baseline alanine aminotransferase (ALT),HBV DNA load,HBsAg and HBeAg levels as well as CVR cumulative rates at different time points during Entecavir treatment were retrospectively analyzed.The cumulative rate of CVR was estimated using Kaplan-Meier method,and the difference in cumulative CVR rates was studied with Log-rank test.Cox's proportional hazards regression model was used to analyze the factors associated with CVR during Entecavir treatment.Results The cumulative rates of CVR during Entecavir treatment in HBeAg positive CHB patients were 54.5％ (87/157),74.3％ (106/129),80.2％ (109/119) and 86.8％ (110/112) at 48,96,144 and 192 weeks,respectively.Log-rank test showed that female patients and patients with genotype B,high baseline ALT level or low baseline HBV DNA load had higher CVR rates (x2 =15.601,11.542,17.021 and 10.094,all P ＜ 0.01).Cox's proportional hazards regression model showed that female was the only associated factor for CVR in Entecavir treatment among HBeAg positive CHB patients [hazard ratio (HR) =3.015,95％ confidence interval (CI):1.875-4.968,P ＜ 0.01].Conclusion CVR rate is increasing with the course of Entecavir treatment in HBeAg positive CHB patients,and CVR is more likely to occur in female patients.

Objective To study the mechanism of serum thyroxin and insulin change after hemihepatectomy. Methods The hemihepatectomy was performed in rabbits, the fasting peripheral blood samples were drawn on the day prior to surgery, and 24 hour, 48 hour, the first week, one month after operation respectively for monitoring the serum thyroxin and insulin.Results The level of TT 3 was (1.93?0.47) nmol/L, TT 4 (53.56?8.4) nmol/L preoperatively. The levels of TT 3 and TT 4 significantly decreased at 24 hour postoperatively, and gradually rose at 48 hour and up to normal levels in the first month postoperatively. The level of insulin rapidly rose immediately after operation, and began to decrease in the first week, and returned to the preoperative level in one month after operation. Conclusions The syndrome of normal thyroid disease and the syndrome of non thyroid disease can occur after hemihepatectomy; and hyperinsulinemia also can occur after hemihepatectomy.

Objective To seek a rational method of estimating the demands for medical services so as to work out regional health planning in a scientific way. Methods A metropolis including 19 counties and districts was selected as a region and demands for medical services were forecasted via retrospective analysis and the econometric model. Results A model of the demands for outpatient and inpatient services was obtained based on the impact of many social and economic factors on medical health services, and illustrations were given to indicate the demands for medical health services in the 19 counties and districts in future when prices should rise by 15% and 20%. Conclusion The econometric model can be used as a tool for estimating the demands for medical health services, and yet improvements need to be made.

Methods The expression of CD151, c-Met and integrin alpha3, alpha6 in 71 patients with PDAC and 10 samples of normal pancreas tissues were detected by immunohistochemistry, and the relationship between the expression of CD151, c-Met and integrin alpha 3, alpha 6 and the clinicopathological features, prognosis of these patients was analyzed. Results The positive expression rates of CD151, c-Met and integrin alpha 3, alpha 6 in PDAC were 81.69% (58/71) , 69.01% (49/71), 69.01% (49/71) and 84.51% (60/71) , and there was no expression in normal pancreas tissues. The expressions of CD151, c-Met were significantly associated with TNM stage and lymph node metastasis (P < 0.05). The expression of CD151 was positively correlated with the expressions of c-Met and integrin alpha3, alpha6 (r =0.583, P =0.000, r = 0.457;P =0.000, r = 0.671 ;P =0.000). Univariate analysis suggested the expression of CD151, c-Met and integrin alpha3, alpha6 was associated with survival (P<0.05). Multivariate analysis suggested the expression of CD151, c-Met was the independent prognostic factor for post-operative survival. Conclusions CD151, c-Met and integrin alpha3, alpha6 play a role in the development, metastasis and prognosis of PDAC, and they might be new markers to predict biological behavior and the prognosis of PDAC patients.

OBJECTIVE: To identify pathogenic mutation of TSC1 and TSC2 genes in a patient with long-time misdiagnosis of epilepsy. METHODS: Peripheral blood samples and clinical data of the patient and her 2 parents were collected. Potential mutation of TSC1 and TSC2 genes were detected by direct sequencing. RESULTS: The patient had frequent episodes of epilepsy in addition with Shagreen patches for 10 years. A frame-shifting mutation c.2509_2512delAACA was detected in exon 20 of the TSC1 gene. This same mutation was not found in her unaffected parents. CONCLUSION The recurrent frame-shifting mutation c.2509_2512delAACA (p.Asn837ValfsX11) of the TSC1 gene probably underlies the disease in this patient.
