Objective To investigate the clinical characteristics and currently treatment status of intractable ulcerative colitis (IUC). Methods A retrospective analysis was conducted on the data of inflammatory bowel disease patients, who were hospitalized in Sir Run Run Shaw Hospital, School of Medicine, Zhejiang University, from January 1999 to December 2009. According to the reaction to glucosteroids (GCS) treatment, they were divided into GCS effective group and intractable group. The general data, lesion, clinical symptoms and laboratory findings of these two groups were compared.Further treatments and the results of intractable group were analyzed. Results Totally 234 UC patients were enrolled, of which 37.6％ (88/234) patients received GCS treatment, intractable group and effective group took up 23.9％ (21/88) and 76.1％ (67/88) respectively. There was no significant difference of lesion between two groups (P＞0.05). Compared with effective group, the proportion of intractable group was higher in moderately severe bellyache[38. 1 ％ (8/21) vs 13. 4％ (9/67), P＝0.012, OR＝3.97, 95％CI:1.29～12.23], anemia[61.9％(13/21) vs 32.8％(22/67), P＝0.018,OR＝3.32, 95％CI:1.20～9.20], thrombocytosis[57.1％(12/21) vs 29.9％(20/67), P＝0.023,OR＝3.13, 95％ CI: 1.14 ～8.61]and hypoalbuminemia[38.1 ％ (8/21) vs 11.9％ (8/67), P＝0.007, OR＝4.54, 95％CI: 1.44～ 14.32]. Some patients of intractable group could be remission through extending period of GCS treatment, adding the immunomodulators or biological agents and intestinal segment excision. Conclusion UC patients with moderately severe bellyache, anemia,thrombocytosis, hypoalbuminemia at the onset of disease, which may indicate relatively poor response to GCS treatment. Immunomodulators, biological agents and surgery are the further treatment for IUC patients.

Objective:To investigate the cytokine profile expressed by CIK cells.Methods:CIK cells were induced from peripheral blood mononuclear cells in the presence of IFN-?,IL-1?,IL-2 and mAb against CD3. The phenotype and characterization of CIK cells were identified by flow cytometric analysis.Cytokine expression profiles were determined at mRNA level by semi-quantitative RT-PCR.Results:The percentage of CD3~+CD56~+ positive cells reached up to or higher than 50%.CIK cells couldn't express IFN-?、IFN-? and IFN-? under this kind of condition. But they could express IFNs principally on day 10 to 20. The level of ILs went down after steadily expressed on day 6 to 10(or 20).TNF-? and TRAIL constitutively expressed during the culture period in vitro. TNF-? maintained high expression on day 20.TGF-?_1 mainly expressed on day 30.Conclusion:CIK cells can widely express various kinds of cytokines in vitro.

Objective To compare the displacements of the clips in the cavity measured with orthagonal kilovoltage (KV) X-my plain film in conditions of moderate deep inspiration breathing hold(mDIBH) and free breath (FB), and compare the margins from clinical target volume (CTV) to planning target volume (PTV) based on the displacements. Methods Before radiotherapy, 2 and 5 sets of orthogonal KV plain film were respectively collected in mDIBH and FB group, then the automatic registration of the reconstructed KV plain film and DRR derived from the planning OF images was finished. In conditions of mDIBH and FB, the displacements of the selected clip at the same location in the different directions and of the different selected clips in the same direction were compared. The margins in three dimensional directions were calculated and compared in conditions of mDIBH and FB . Results In FB hold group, the difference of displacement in left-right (LR), cranial-caudal (CC) and anterior-posterior (AP) directions were statistically significant between the clips at the cranial and caudal border of the cavity (9. 7 mm and 10. 6 nun (Z = -2. 12,P =0. 037) ,7. 3 mm and 8. 3 mm (Z = -2. 31 ,P=0. 041) ,15.5 mm and 16. 1 nun (Z = -2. 32,P = 0. 041)), but not statistically significant for the clips at the bottom and lateral P=0.814),15.7 mm and 16.5 mm (Z=-0.26,P=0.856)). The corresponding differences in the different directions were statistically significant (5.0 mm and 7. 8 mm(Z = -2. 31, P =0. 036), 5.0 mm and 9. 3 nun (Z= -2. 21,P=0. 021),7. 8 mm and9.3 mm (Z= -2. 11,P=0.041)). In FB group, the differences of the displacements of the four selected clips were statistically significant in CC and AP directions (7.3 mm and 8.4 mm (Z= -2.45,P=0.021), 15.5 mm and 16.5 mm (Z= -2.41,P= 0.043)), but not in LF direction (10.6 nun and 10.6 mm (Z= -0.24,P=0. 815)). In mDIBH group, the displacements in LF direction were statistically significant (4. 4 mm and 5.4 mm (Z = -2. 31, P = O. 031)), but not in CC and AP directions (8. 6 mm and 8.6 mm (Z =-0. 21, P = 0. 815), 10. 5 mm and 10. 8 mm (Z = -0. 27 ,P =0. 754)). There were statistically significant difference of the margins in LF and AP directions (9.7 mm and 5.0 mm (Z= -2.34,P=0.029),15.5 mm and 9.3 mm (Z= -2. 31,P= 0.021)), but not in CC direction (7.3 mm and 7. 8 mm (Z= -0.29,P =0.770)) between mDIBH and FB conditions. Conclusions The margins extended from CTV to PTV for EBPBI should be determined based on the respiratory status, border location and border direction.

Objective To evaluate the effects of electroacupuncture (EA) on synaptic interface structures around a cerebral infarct and evaluate how learning and memory relate to synoptic structure. Methods Forty-eight male, adult Wistar rats were divided randomly and equally into an EA group and a control group after models of ische-mic brain injury had been established. Each group was then divided into 1 week, 2 week and 3 week sub-groups. In the EA group EA was started 24 hours after the operation at the Baihui (DU20) and Da Zhui (BUI4) points and continued for one week, two weeks or three weeks. The control group was fed in normal cages and had no special treatment. Synoptic substructures in the hippocampal CA3 area of the ischemic side were assessed morphologically and quantitatively. Results The synaptic curvatures and postsynaptic density (PSD) an well as the width of the ac-tive area increased significantly in the EA group compared with the control group. Morris water maze learning ability in the EA group exceeded that in the control group. Spatial probe test results also significantly improved in the EA groups compared with the control groups. Conclusions Learning and memory improved in the injured rats following EA, and this is likely to be related to synaptic changes and synaptic plasticity increasing.

Long noncoding RNA (lncRNA) is a class of RNA molecules that longer than 200 nucleotides.lncRNA is lack of functional open reading frames and has no protein coding ability.Recently, accumulating evidences indicate that lncRNA plays active roles in tumor carcinogenesis and progression.The aberrant expression of lncRNA is significantly correlated with the growth,metastasis,and therapy-resistance of digestive system tumors.Thus,lncRNA may be served as new targets for the diagnosis,treatment,and progno-sis of patients with digestive system tumors.

Objective To investigate the expression levels of serum LINC00978 in gastric cancer patients and its correlation with clinicopathological characteristics,and evaluate its clinical diagnostic value.Methods The expression levels of LINC00978 in gastric cancer cells and serum samples from the patients with gastric cancer or gastric benign diseases and healthy controls were detected by real-time qRT-PCR,and its correlations with clinicopathological parameters were analyzed.The diagnostic efficacy of serum LINC00978 was evaluated by the receiver operating characteristic (ROC) curve.Results The expression levels of LINC00978 in MGC-803 cells were significantly higher than that in GES-1 cells (18.88 ± 1.15 vs 1.00 ± 0.03,t =-21.926,P ＜ 0.05).The expression levels (median[P25,P75]) of serum LINC00978 in gastric cancer patients (3.525 [1.385,8.954]) were significantly higher than those in the patients with gastric benign diseases (0.419 [0.258,1.369],Z =-4.834,P ＜ 0.01) and healthy controls (0.814 [0.351,2.510],Z =-4.686,P ＜ 0.01).The expression levels of serum LINC00978 in gastric cancer patients were significantly related to lymphatic metastasis (r =0.448,P ＜ 0.01),invasive depth (r =0.369,P ＜ 0.01) and TNM stage (r =0.383,P ＜ 0.01),and those after operation significantly lower than before operation (0.17 [0.15,0.39] vs 0.98 [0.59,1.61],Z =-5.731,P ＜ 0.01).There was no significant difference in serum LINC00978 levels between the patients with gastric benign diseases and healthy controls (Z =-1.693,P ＞ 0.05).The area under the ROC curve (AUCROC) and 95％ confidence interval (CI) of serum LINC00978 levels in the diagnosis of gastric cancer were 0.807 and 0.732-0.882,respectively.When the cutoff value was 1.806,the sensitivity and specificity for the diagnosis of gastric cancer were 71.4％ and 75.9％,respectively.Conclusion The expression levels of serum LINC00978 in gastric cancer patients increase and are related to lymphatic metastasis,invasive depth and TNM stage,which may be served as a novel biomarker for the diagnosis of gastric cancer.

Objective:To analyze the gene mutation, clinical manifestations and prognosis of children with steroid resistant nephrotic syndrome (SRNS), and to provide reference for the treatment of hereditary SRNS in children.Methods:The clinical data of 29 patients with SRNS and whole exon sequencing (WES) diagnosed in Xi′an Children′s Hospital from January 1, 2018 to December 31, 2020 were retrospectively analyzed.Results:In 29 cases of SRNS with genetic testing, 10 cases (34.5%) were gene mutations, including 2 cases of congenital nephrotic syndrome. The onset age of the patients with gene mutation ranged from 0.1 to 10.7(4.06±3.73)years, and the median age of onset was 3.3 years. The clinical type was mainly nephritis (8/10), and the pathological type was mainly focal segmental glomerulosclerosis (FSGS) (5/7). The main mutant genes were NPHS1 (2 cases), NPHS2 (2 cases), WT1 (2 cases), SMARCAL1 (1 case), COQ8B (1 case), TRPC6 (1 case) and COL4A3 gene (1 case). The main types of genetic variation were missense mutations, and 6 (60%) cases were new mutations that had never been reported in the database containing human pathogenic mutations before. Compared with the non-gene mutation group, 24 hour urinary protein was higher [(177.92±164.59)mg/(kg·24 h) vs (84.99±40.79)mg/(kg·24 h)] in gene mutation group, with statistically significant difference ( P<0.05). In the gene mutation group, there were 2 cases of complete remission, including 1 case of complete remission treated with coenzyme Q10, 1 case of partial remission, and 8 cases of immunosuppression treatment, with an effective rate of 2/8, while in the non-gene mutation group, the effective rate of immunosuppression treatment was 17/19, with statistically significant difference in prognosis between the two groups ( P<0.05). Conclusions:The pathological type of children with hereditary SRNS is mainly FSGS, which are often ineffective to immunosuppressive therapy, poor prognosis and easy to progress to end-stage renal disease. Gene detection is of great significance for etiological diagnosis, treatment and prognosis evaluation in children with SRNS.
