Objective To explore the correlative factors and management of secondary high intraocular pressure(IOP) after vitreoretinal surgery for proliferative diabetic retinopathy(PDR). Methods The data of 51 patients(54 eyes) with PDR after vitreoretinal surgery were collected.The incidence of secondary high IOP was obtained,and the correlative factors leading to high IOP were analysed.Besides,the therapeutic effects of management were observed. Results Twenty-six patients(26 eyes) experienced postoperative high IOP,with the incidence of 48.15%(26/54).It was revealed that the preoperative retinal detachment,the combined performance of crystal phacoemulsification,the practice of intraocular tamponade and the postoperative posterioruveitis were related to the occurrence of high IOP(P

Objective To study the relationship of hope level and social support of gastrointestinal cancer patients, and to investigate the effective measures to improve their hope. Methods Questionnaires were filled in by 201 gastrointestinal cancer patients and descriptive correlative study was used. Results The level of hope among those patients was from medium to high. Social support of gastrointestinal cancer patients was aignificantly higher than that of healthy people. Positively correlation was found between social support and level of hope of gastrointestinal cancer patient(r=0.154 ,P<0.05). Conclusions Social support was closely related to the level of hope of gastrointestinal cancer patients. Nurses should pay attention to the effect of social support system to improve their level of hope.

Objective To investigate the correlation between family care and self-care in heart failure patients and to explore effective measures of improving self-care of heart failure patients. Methods The Family APGAR and Self-care of Heart Failure Index were used to investigate 144 heart failure inpatients. The correlation between family care and self-care was analyzed. Results Family care scores was high (7.49 ±3.03). The Level of total serf-care was low ( 156.23 ± 38.51 ): the score of self-care maintenance, self-care management and self-care confidence was (54.38 ± 10.41 ), (49.14 ± 21.33) and (53.02 ±13.74)respectively. Family care was positively correlated with self-care in heart failure patients (r =0.21 ,P ＜0.05 ).Conclusions Heart failure patients should enhance the skills and confidence of coping symptoms. Since family care has positive effect on self-care of patients, it is important to emphasize family function on caring heart failure patients.

Objective To explore the metabolic abnormality in patients with first-episode schizophrenia and effect of atpical antipsychotics olanzapine on them.Methods Thirty patients with first-episode schizophrenia,admitted to our hospital from February 2010 to February 2011,and 40healthy controls were chosen in our study; patient group was given oral olanzapine for 4 week.The height,weight,waistline and hipline were measured before and after treatment,and the total cholesterol (TC),triglyceride(TG),high-density lipoprotein(HDL),low-density lipoprotein(LDL),apolipoprotein AI(aPOAI),apolipoprotein B100(aPOB100),lipoprotein a(LPa),fasting blood-glucose,fasting insulin and C peptide levels were detected before and after treatment; and the insulin resistance(IR)index,waist hip ratio(WHR)and body mass index(BMI)were calculated before and after treatment; metabolic index were compared between patients and controls,and patients before and after the treatment.Results The HDL and aPOA1 levels in patient group were significantly lower,and the WHR,IR index,fasting insulin and C peptide levels were obviously higher as compared with those in the controls(P＜0.05).The BMI,waist circumference,WHR,the IR index,the insulin,TC,TG,LDL and aPOB100 levels after treatment were significantly increased as compared with those before treatment(P＜0.05).Conclusion There may be some inborn metabolic abnormality factors in patients with first-episode schizophrenia; the high incidence of metabolic abnormality in patients with schizophrenia may be the result of combined action from antipsychotics and inherit susceptibility.

OBJECTIVETo study the clinicopathologic features, immunohistochemical findings, EBV and c-myc gene status of intra-abdominal non-Hodgkin B-cell lymphoma occurring in children.

METHODSSeventy-four cases of pediatric intra-abdominal non-Hodgkin B-cell lymphoma were retrieved from the archival file. The cases were classified according to the 2008 WHO classification. Tissue microarray including tumor tissues from all the 74 cases was produced. Immunohistochemical study (SP method) for CD20, CD3, CD79a, CD10, bcl-6, MUM1, bcl-2, CD43, CD38 and Ki-67 was performed. In-situ hybridization for Epstein-Barr virus-encoded RNA (EBER) and fluorescence in-situ hybridization for c-myc gene were also carried out.

RESULTSAmongst the 74 cases studied, 65 of them (87.8%) were Burkitt lymphoma (BL), 4 cases (5.4%) were diffuse large B-cell lymphoma (DLBCL) and the remaining 5 cases (6.8%) showed features in-between DLBCL and BL (DLBCL/BL). The patients often presented with abdominal pain, abdominal masses, ileus and intussusception. The ileocecal bowel wall and mesenteric lymph nodes were commonly involved. The lymphoma cells were of high histologic grade and suggested an aggressive clinical behavior. The staining for CD20 and CD79a were positive in all of the cases, while CD3 was negative. The positive rates of CD10, bcl-6, bcl-2, MUM1, CD43, CD38 and EBER in BL were 96.9% (63 cases), 95.4% (62 cases), 0 (0 case), 23.1% (15 cases), 70.8% (46 cases), 96.9% (63 cases) and 41.5% (27 cases), respectively. Fifty-four cases carried translocation of c-myc gene. As for DLBCL, the positive cases of CD10, bcl-6, bcl-2, MUM1, CD43, CD38 and EBER were 3 cases, 2 cases, 3 cases, 2 cases, 2 cases, 2 cases and 0 case, respectively. One of these cases showed c-myc gene translocation. Amongst the 4 cases of DLBCL, 2 of them belonged to germinal center B-cell-like subtype, while the remaining 2 cases were of non-germinal center B-cell-like subtype. The expression rates of CD10, bcl-6, bcl-2, MUM1, CD43, CD38 and EBER in DLBCL/BL were 5/5, 4/5, 0, 3/5, 5/5, 3/5 and 0, respectively. Three of the cases were positive for c-myc gene translocation.

CONCLUSIONSThe majority of pediatric intra-abdominal non-Hodgkin B-cell lymphoma belonged to BL. They have characteristic clinical presentation and sites of predilection and are often associated with an aggressive clinical behavior. Thorough morphologic assessment, immunohistochemistry and in-situ hybridization play an important role in subtyping this group of lymphoid malignancy.

Bladder cancer is one of the most common types of cancer. Most gene mutations related to bladder cancer are dominantly acquired gene mutations and are not inherited. Previous comparative transcriptome analysis of urinary bladder cancer and control samples has revealed a set of genes that may play a role in tumor progression. Here we set out to investigate further the expression of two candidate genes, centromere protein U (CENPU) and mitochondrial ribosomal protein s28 (MRPS28) to better understand their role in bladder cancer pathogenesis. Our results confirmed that CENPU is up-regulated in human bladder cancer tissues at mRNA and protein levels. Gain-of-function and loss-of-function studies in T24 human urinary bladder cancer cell line revealed a hierarchical relationship between CENPU and MRPS28 in the regulation of cell viability, migration and invasion activity. CENPU expression was also up-regulated in in vivo nude mice xenograft model of bladder cancer and mice overexpressing CENPU had significantly higher tumor volume. In summary, our findings identify CENPU and MRPS28 in the molecular pathogenesis of bladder cancer and suggest that CENPU enhances the progression of bladder cancer by promoting MRPS28 expression.

To identify adulterants from medicinal plants of Bletilla H. G. Reichenbach, the suitable candidate DNA barcoding of Bletilla was evaluated. In this study, the internal transcribed spacer (ITS) of nuclear ribosomal DNA, the LFY homologous gene intron 2 and chloroplast ycfl gene were amplified and sequenced from forty-one samples. The intra-specific and inter-specific divergences of Bletilla were calculated, and the identification efficiency was assessed using Barcoding Gap, NJ tree by K2P distance and BLAST1 method. The result showed the intra-specific divergence of nrDNA ITS and ycJfl (0.022-0.106 and 0.017-0.106) were obviously higher than the inter-specific divergence (0-0.012 and 0-0.015), and four species of Bletilla were also accurately distinguished in NJ trees. Whereas, there was no Barcoding Gap on LFY homologous gene intron 2, thus it cannot effectively identify species of Bletilla. Using NJ tree of nrDNA ITS and ycfl gene, powdery medicine and the adulterants of Bletilla were successfully unidentified. In conclusion, nrDNA ITS and ycfl can be used as a potential DNA barcoding to identify the medicinal plants in Bletilla and its adulterants. There were only three basic differences on nrDNA ITS between "Jujing baiji" and Bletilla striata of Lu'an in Anhui province, and two basic differences in ycfl. Based on morphological and molecular data, "Jujing baiji" could be recognized as the species of Bletilla striata.
