Objective To translate and revise the Individualized Care Scale-Patient Version(ICS-P) into Chinese,then to assess the reliability and validity of the Chinese version of the Individualized Care Scale-Patient Version (C-ICS-P).Methods Standard forward-back translation techniques were used in the translation of the ICS-P according to the Brislin translation model.Cross-cultural revision of the translated ICS-P was carried out through group discussion and pretesting.Totally 223 patients were recruited through convenience sampling method from a tertiary hospital in Changsha and investigated using general information questionnaire and the C-ICS-P,and its reliability and validity were assessed.Results The C-ICS-P contained two subscales,and both C-ICS-P-A and C-ICS-P-B contained 3 factors explaining 61.330％ and 65.263％ of the total variance.The dimensions of C-ICS-P-A were clinical characteristics (6 items),personal life characteristics (4 items) and participation willingness (5 items);the dimensions of C-ICS-P-B were clinical care (6 items),personal life care (4 items) and decisional control over care (5 items).The Cronbach's α coefficients of C-ICS-P-A and its dimensions were 0.897,and 0.730～0.774;the Cronbach's α coefficients of C-ICS-P-B and its dimensions were 0.909,and 0.688～0.754.Split-half reliability was 0.856 for C-ICS-P-A and 0.688～0.754 for its dimensions;split-half reliability was 0.889 for C-ICS-P-B and 0.750～0.758 for its dimensions.Analysis of content validity of the C-ICS-P indicated that I-CVI was at least 0.83,S-CVI was 0.943.Conclusion The reliability and validity of C-ICS-P are satisfactory and well meet the requirements of psychological measurement,indicating C-ICS-P is a reliable and valid instrument in the context of Chinese culture.

Objective To analyze the long-term results of rituximab combined with whole brain radiotherapy and 3-dimentional conformal radiotherapy (3D-CRT) in treatment of patients with primary central nervous system lymphoma (PCNSL). Methods 23 postoperative patients younger than 60 years old were treated. Whole brain radiotherapy with dose of 32.4 Gy were performed and lesions were followed by 3D-CRT with dose of 18 Gy.A dose of rituximab (375 mg/m2) was infused on day 1 (once a week for six weeks).The overall survival was analyzed by using Kaplan-Meier.Results 19 patients(82.6 ％) was complete remission 3 patients (13.0 ％) was part remission,14 patients (60.9 ％) was progression-free survival was 26 months (17-34 months). The overall survival was 40 months (29-55 months). Toxicity was moderate without grade 3-4 neurotoxicity toxic events. Conclusions Radiotherapy (whole brain radiotherapy with sequential 3D-CRT)combined with rituximab seems to yield substantial long-term survival with moderate toxicity for the treatment of the younger patients with PCNSL.

Objective: To screen the differential expression profile of circular RNA (circRNA) in pancreatic cancer and analyze its potential function. Methods: Four pairs of pancreatic cancer tissues and corresponding adjacent pancreatic tissues were selected for high⁃throughput sequencing , and the differentially expressed circRNA was screened according to fold change > 2 and P < 0. 05. qRT⁃PCR was used to detect the expression of 5 randomly selected differentially expressed circRNA in 20 pairs of pancreatic cancer tissue samples. GO and KEGG enrichment analysis of differentially expressed circRNA was performed , and the top 50 circRNA⁃microRNA interaction network was constructed. The relationship between hsa_circ_0046523 and the clinicopathological features of pancreatic cancer was further analyzed , and the effects of hsa_circ_0046523 on the proliferation , migration and invasion of pancreatic cancer cells were observed by functional experiments. Results: A total of 17 182 circRNA were predicted by high⁃throughput sequencing , of which 302 circRNA were differentially expressed including 137 circRNA were upregulated and 165 circRNA were downregulated in pancreatic cancer tissues. The qRT⁃PCR results showed that the expression levels of hsa_circ_0046523 , hsa_circ_0004220 and hsa_circ_0000690 in pancreatic cancer tis⁃sues were significantly upregulated (P<0.05)，while the expression levels of hsa_ ir_0008676 and hisa _ circ_0004416 were significantly downregulated (P<0.05）.which was consistent with the sequencing results.GO analysis indicated that differentially expressed circRNA were mainly involved in substrate-dependent cell migration, protein kinase complex and cytoskeletal protein bindinig.KEGG pathway enrichment analysis showed that differentially expressed circRNA were mainly involved in protein digestion and absorption , ABC transporters , central carbon metabolism in cancer,and glycineserine and threonine metabolism pathways.The expression level of hsa_ circ_0046523 was closely correlated with tumor differentiation (P=0.002),T stage (P=0.006),lymph node metastasis (P=0.011) and TNM stage (P=0.001).Compared with HPDE6-C7 cells the expression of hsa_circ_0046523 significantly inc increased in pancreatic cancer SW1990, Mia PaCa-2BxPC-3 and Capan-2 ceIls (P<0.05). hsa_circ_ 0046523 knockdown significantly inhibited the proliferation, migration and invasion of pancreatic cancer Mia PaCa⁃2 BxPC⁃3 cells (P < 0. 05) . Conclusion There are characteristic differentially expressed circRNAs in pancreatic cancer tissues , and these differentially expressed circRNAs may be involved in the occurrence and development of pancreatic cancer.

Post-traumatic stress disorder (PTSD) is a psychiatric disease that seriously affects brain function. Currently, selective serotonin reuptake inhibitors (SSRIs) are used to treat PTSD clinically but have decreased efficiency and increased side effects. In this study, nasal cannabidiol inclusion complex temperature-sensitive hydrogels (CBD TSGs) were prepared and evaluated to treat PTSD. Mice model of PTSD was established with conditional fear box. CBD TSGs could significantly improve the spontaneous behavior, exploratory spirit and alleviate tension in open field box, relieve anxiety and tension in elevated plus maze, and reduce the freezing time. Hematoxylin and eosin and c-FOS immunohistochemistry slides showed that the main injured brain areas in PTSD were the prefrontal cortex, amygdala, and hippocampus CA1. CBD TSGs could reduce the level of tumor necrosis factor-
