Objective To evaluate the reliability and validity of hepatocellular carcinoma (HCC)using the liver imaging reporting and data system (LI-RADS).Methods By using the LI-RADS v2013.1,two radiologists evaluated 1 62 patients with cirrhosis or with a risk of HCC according to an inclusion criteria.The Kappa value was used to evaluate the consistency between two different diagnoses and was compared with pathological and follow-up results.The accuracy of the LI-RADS was assessed including sensitivi-ty,specificity,positive predictive value,negative predictive value,positive likelihood ratio,negative likelihood ratio and accuracy rating.Results In all 1 62 patients,there were HCCs in 97 patients including 7 patients belonging to the LR3,benign diseases in 50,and other kinds of malignancy in 1 5.The Kappa value was 0.882 (P =0.000)between two observers on LI-RADS grading. The sensitivity,specificity and accuracy rating of LI-RADS grading in diagnosing HCC was 100.00%,91.30%,and 97.06%,re-spectively.Conclusion The LI-RADS has high consistency and stability in evaluation and diagnosis of HCC by enhanced CT.LR3 di-agnosis should be cautious because of a susceptible development to HCC,which can be improved through the combination of clinic and laboratory examination.

Objective To explore the expression of PIWIL1 protein and DICER enzyme in hepa tocellular carcinoma (HCC) and their significance.Methods Immunohistochemical method was used to detect the expression of PIWIL1 and DICER in 47 cases of HCC and the adjacent HCC tissues.Western blot method was used to detect the expression of PIWIL1 and DICER in 31 cases of fresh HCC tissues and their adjacent HCC tissues.The relationship between PIWIL1 and DICER and their relationships were analysed with clinical features.12 cases of normal liver tissues were used as control group.Results The expression of PIWIL1 was high in HCC but low in normal liver tissues (P＜ 0.05).The expression of DICER was high in normal liver tissues but low in HCC (P＜0.05).The expression of PIWIL1 was positively correlated with invasion to adjacent tissues and histological differentiation (P＜0.05).The expression of DICER was negatively correlated with invasion to the adjacent tissues and histological differentiation (P＜0.05).There was a negative correlation between PIWIL1 and DICER (P＜ 0.05).Conclusions High expression of PIWIL1 and low/missing expression of DICER was related to pathological differentiation and invasion of adjacent tissues.

Recent studies find that the expression of hepatoma-derived growth factor (HDGF) is closely correlated with the tumorigenesis,progression,metastasis,therapy and prognosis of various malignancies.Though the mechanism of the interaction of HDGF and tumors is still unclear,the research of HDGF serving as a tumor marker in malignancies and a new target for tumor treatment has become a hotspot in the research of tumor.

Objective To investigate the therapeutic effect of stereotactic surgical treatment and postoperative cognitive functions in patients with treat-resistant obsessive compulsive disorder(TRO). Methods Twelve patients with TRO receiving MRI stereotactic bilateral anterior capsulotomy was retrospectively studied. The evaluation was conducted using the Yale-Brown obsessive compulsive rating scale (Y-BOCS),Wechsler Adult Intelligence Scale-Revised in China (WAIS-RC),Wechsler Memory Scale-Revised in China(WMS-R), Modified Version of Wisconsin Card Sorting Tests (M-WCST) before and 6 months after the operation. Results The scores of Y-BOCS was 5.00(1.00,12.25) and 25.00 (20.25,32.00) after and before surgery, respectively. The scores of Y-BOCS were significantly lower after surgery than before (P<0.05). Most of cognitive function tests were not significantly different in TRO between pre-operation and 6 month post-operation (P>0.05).There were significant improvements in several cognitive tests after surgery including im-mediately logical memory 20.00(12.50,24.00),delayed logical memory16.50(11.50,21.75),immediately visual reproduc- tion 12.00(11.00,14.00),delayed visual reproduction11.00(8.50,14.00) and block design test scores 36.50(29.75,46.75), immediately logical memory14.00(13.00,18.75),delayed logical memory 14.50 (8.75,17.00),immediately visual reproduc-tion 11.00(6.50,11.75),delayed visual reproduction 8.50(6.25,10.00) and block design test scores 30.50(21.00,41.50) (P<0.05). Conclusions MRI-guided bilateral anterior internal capsulotomy is effective and safe treatment for patients with TRO and can improve their cognitive function.

Objective To study the memory disorder perception characteristics of subjective memo-ry complaints(SMCs)and to analyze the influencing factors. Methods 302 subjects conforming to the in-clusion criteria were selected.All the subjects completed the illness perception questionnaire-memory of Chi-nese version(IPQ-M). Results (1)There was no statistical difference between the score of social compari-son(2.95±0.78)and the middle value 3.The differences between the score of the remaining dimensions of memory impairment perception(timeline acute/chronic(3.57 ± 0.89),consequences(2.24 ± 0.77),timeline stability/decline(3.71±0.88),personal control(blame)(3.61±0.92),personal control(helplessness)(3.31± 0.73),emotional representation(2.29 ± 0.70),treatment control(2.78 ± 0.67),illness coherence(3.14 ± 0.64))and the middle value 3 were statistically significant(all P<0.05).(2)Gender,education level,living condition,marital status,economic condition,family history of dementia and knowledge education of dementia were the influencing factors of memory perception of SMCs. Conclusion The memory complaining people are less aware of the related knowledge of memory decline,and there are more errors and negative percep-tions.The factors that affect the perception of memory disorders are complex.

Objective To compare the difference of T-stage between Chinese 2017 staging system and the 2008 staging system for nasopharyngeal carcinoma,and to investigate the optimization of T-stage and provide suggestions for further revision.Methods The MRI data of 183 patients with histology-proven newly diagnosed nasopharyngeal carcinoma in our hospital were enrolled from September 2009 to May 2017.All the anatomic sites mentioned in the two staging systems were marked,and all patients were staged according to the 2017 staging system and the 2008 staging system for nasopharyngeal carcinoma.Comparisons of T-stage were made between the two staging systems.Results Involvement of oropharynx,nasopharynx,prevertebral muscles,cervical vertebra,hypopharynx and orbit were 100％ accompanied with other same or more advanced T-stage classifications.The invasion rates of the cervical vertebra,orbit and hypopharynx were very low (all ＜ 5.00％).The incidence of involvement of pterygoid structure was 15.30％,most of which incorporated with erosion of skull base,only 1 case was invaded alone.All cases of involvement of paranasal sinuses were incorporated with erosion of skull base.Compared with the 2008 staging system,the consti-tuent ratio of T1 + T2 in the 2017 staging system increased from 36.61％ to 61.75％,and that of T3 + T4decreased from 63.39％ to 38.25％,the constituent ratio of T-stage between the 2017 staging system and the 2008 staging system was significantly different (x2 =26.94,P ＜ 0.001).There was moderate consistency of T-stage between these two staging systems (Kappa =0.514,P ＜ 0.001).Conclusion The T-stage of 2017 staging system still has a larger simplification and optimization space.Therefore,according to the principle of concise,the T-stage parameters including oropharynx,nasopharynx,prevertebral muscles,paranasal sinuses,cervical vertebra,orbit and hypopharynx are recommend to delete,and it does not have an impact on the composition of T-stage.We suggest that the pterygoid structure shall combine with the skull base to be one anatomical structure.

Objective: To compare survival outcomes between cervical adenocarcinoma (ADC) and squamous cell carcinoma (SCC) using a propensity score matching (PSM) analysis based on the Surveillance, Epidemiology, and End Results (SEER) Program. Methods: Patients diagnosed with cervical cancer between 1998 and 2016 were identified from the SEER database. The Kaplan-Meier method and Cox regression analysis were used to analyze survival. A subgroup analysis of overall survival (OS) between patients with ADC and SCC was performed after the 1:1 PSM analysis. Results: Of the 33,148 patients, 24,591 (79.19%) had SCC and 8,557 (25.81%) had ADC. In the unmatched cohort, after adjustment in multivariate analysis, patients with ADC had a worse prognosis than patients with SCC (hazard ratio [HR]=1.12; 95% confidence interval [CI]=1.07– 1.18; p<0.001). In the propensity matched cohort, Kaplan-Meier analysis and subgroup analysis showed that ADC was associated with a worse prognosis than SCC (p=0.001). An analysis stratified by SEER stage revealed a worse prognosis for patients with ADC patients presenting with a regional disease than patients with SCC (HR=1.24; 95% CI=1.14–1.36 p<0.001), but no statistically significant differences were observed between the localized disease (HR=0.97; 95% CI=0.86–1.10; p=0.664) and distant disease (HR=1.09; 95% CI=0.97–1.22; p=0.162) subgroups. Conclusion The significant differences in survival outcomes between patients with cervical ADC and SCC were only observed in the regional disease subgroup, but not in the localized disease and distant disease subgroups.
