Objective: To explore the diagnostic values of HK2 testing and single-cell sequencing in the urothelial carcinoma (UC). Methods: The qualified urine specimens of 265 suspected UC patients or postoperative patients from the Cancer Hospital of Chinese Academy of Medical Sciences, Beijing, China were collected. Both exfoliative cytology and HK2 testing were performed on clinically suspected UC or postoperative patients. The performance of diagnostic cytology and HK2, including consistency, sensitivity, specificity, positive predictive value and negative predictive value, was evaluated based on histopathological, clinical and imaging diagnosis. Isolated HK2 metabolically abnormal cells were subject to single-cell sequencing to verify the reliability of HK2 detection performance and to explore the molecular characteristics of UC. Results: The concordance rate of HK2 testing and cytology for detecting UC was 90.3% (102/113, Kappa=0.604). Compared with cytology, the sensitivity of HK2 was significantly higher (85.2% versus 75.6%, P=0.024). The detection sensitivity of combined HK2 testing and cytology was increased to 91.1%. HK2 testing was significantly more sensitive than cytology for diagnosing UC in the upper urinary tract (81.8% versus 65.5%, P=0.022). It was also more sensitive than cytology for diagnosing early-stage UC (82.6% versus 69.5%, P=0.375) and low-grade UC (69.6% versus 47.8%, P=0.125). Single-cell sequencing of the ten patients, whose samples were positive for HK2, demonstrated highly concordant copy number variations (CNVs) in tumor cells from the same UC patient, with heterogeneity in CNV profiles among different patients. Deletion of chromosome 8p was found in 3 of the 4 urine samples of renal pelvis UC. The 2 patients with benign lesions had no CNVs in all sequenced cells. Conclusions: The test for abnormal urinary glycolytic HK2 metabolism can assist urine cytology to improve the sensitivity of UC diagnosis, and it provides a novel and reliable approach for early detection of upper urinary tract UC and lower grade UC. Meanwhile, this study has preliminarily revealed the feasibility of single-cell sequencing in urinary samples, which is expected to improve the diagnostic specificity of HK2 testing.

OBJECTIVETo investigate the relationship between plasma miR-93-5p and the risk of esophageal cancer, as well as the influence of miR-93-5p on the biological function of esophageal cancer cells, exerted through exosomes.

METHODSThe expression of plasma miR-93-5p in esophageal cancer patients and healthy controls was analysed by real-time quantitative PCR. The influence of miR-93-5p on the risk and prognosis of esophageal carcinoma was analyzed by conditional logistic regression and survival analysis. The effect of miR-93-5p on the biological function of recipient cells was investigated by establishing an in vitro donor cell co-culture model. The target gene of miR-93-5p was validated by luciferase reporter assay and Western Blotting.

RESULTSUpregulation of plasma miR-93-5p expression significantly increases the risk of esophageal cancer and is associated with poor prognosis. miR-93-5p transferred by exosomes promotes the proliferation of recipient esophageal cancer cells and affects the expression of PTEN and its downstream proteins p21 and cyclin D1.

CONCLUSIONOur study provides a reference for the identification of biomarkers for the diagnosis and prognosis of esophageal cancer.

OBJECTIVETo evaluate the application effect of Chinese medical clinical pathway for treating attention-deficit hyperactivity disorder (ADHD), and to provide evidence for further improving clinical pathways.

METHODSTotally 270 ADHD children patients were recruited and treated at pediatrics clinics of 9 cooperative hospitals from December 2011 to December 2012. The treatment course for all was 3 months. Scores of attention deficit and hyperactivity rating scale, scores of behavior, Conners index of hyperactivity (CIH), and Chinese medical syndrome scores were compared between before and after treatment. The efficacy difference in various sexes, ages, and disease courses were evaluated by judging standards for Chinese medical syndrome and ADHD.

RESULTSFifteen children patients who entered clinical pathway dropped out, and the rest 255 completed this trial. Compared with before treatment, total scores of attention deficit and hyperactivity rating scale, scores of attention deficit and hyperactivity rating scale, CIH, and Chinese medical syndrome scores obviously decreased (all P < 0.01). The total effective rate in disease efficacy was 87.8% (224/255 cases), and the total effective rate in Chinese medical syndrome curative effect was 87.5% (223/255 cases). The clinical curative effect was not influenced by age, gender, or course of disease when statistically analyzed from judging standards for Chinese medical syndrome or for disease efficacy.

CONCLUSIONIntervention by Chinese medical clinical pathway could improve ADHD patients' symptoms, and its efficacy was not influenced by sex, age, or course of disease.

OBJECTIVETo explore the potential decrease of serum erythropoietin (EPO) level in patients with multiple sclerosis (MS) complicated with anemia.

METHODSThe serum EPO levels were detected in the patients with MS complicated with anemia (MS group, n=31), patients with iron deficiency anemia (IDA group, n=33), and healthy subjects (normal control group, n=80) by enzyme-linked immunosorbent assay (ELISA). Blood routine test, reticulocyte count, hemoglobin, and indexes of liver and kidney function were also detected.

RESULTSThe serum EPO level in MS group was significantly lower than those in IDA group [(101.3±17.6)U/L vs.(166.1±8.7)U/L, P<0.01]. Moreover, the serum EPO level decreased as the severity of anemia in the MS group increased: it was (95.7±9.6), (101.7±8.1), and (123.7±9.3) U/L in patients with mild, moderate, and severe anemia, respectively (P<0.05). Other indicators including blood routine findings, reticulocyte count, hemoglobin, and liver and kidney function parameters showed no significant difference between the MS group and the IDA group (P>0.05).

CONCLUSIONSThe serum EPO level decreases in patients with multiple sclerosis complicated with anemia, and the decreasing levels are related with the severity of anemia. Thus EPO therapy may be beneficial for these patients.

BACKGROUNDWide application of umbilical cord blood transplantation (UCBT) in adult patients is limited by low cell-dose available in one umbilical cord blood (UCB) unit. The aim of this study was to investigate the safety and long-term outcomes of UCBT from unrelated donors in adult and adolescent patients with leukemia.

METHODSThirteen patients with leukemia received double-unit UCBT with human leukocyte antigen (HLA) mismatched at 0 - 2 loci. We analyzed the engraftment, graft-versus-host disease (GVHD) and survival.

RESULTSTwelve evaluable patients (92.3%) had neutrophil and platelet engraftment at a median of 21 days (range, 16-38 days) and 34 days (range, 25 - 51 days), respectively. At day 30, engraftment was derived from one donor in 8 patients (66.7%, 95%CI 40.0% - 93.4%), and from both donors in 4 patients (33.3%, 95%CI 6.7% - 60.0%) with 1 unit predominated. Unit with larger nucleated cell (NC) dose would predominate in engraftment (P = 0.039), whereas CD34(+) cell dose or HLA-match failed to demonstrate any relationship with unit predominance. Only one patient developed grade II acute graft-versus-host disease (aGVHD). Chronic GVHD (cGVHD) was observed in 2 of 11 patients who survived more than 100 days, and both were limited. The median follow-up after transplantation for the 13 patients was 45 months (range 1.5 - 121.0 months) and 72 months (range 41.0 - 121.0 months) for the 8 alive and with full donor chimerism. The 5-year cumulative disease free survival (DFS) was (61.5 ± 13.5)%. Of the 13 patients, 5 patients died in 1 year and 1-year transplantation related mortality (TRM) was 23.1% (95%CI 0.2% - 46.0%).

CONCLUSIONDouble-unit UCBT from unrelated donors with HLA-mismatched at 0-2 loci may overcome the cell-dose barrier and be feasible for adults and adolescents with leukemia.

OBJECTIVETo examine the association between polymorphism of vascular endothelial growth factor(VEGF)1498 C/T,936 C/T and colorectal adenoma genetic susceptibility.

METHODSA case-control study of 224 colorectal adenomas and 200 controls was conducted and VEGF genotypes were determined based on TaqMan-probe assay. The epidemiological factors were collected through questionnaire. Accordingly, the clinicopathological data of each sample were also investigated.

RESULTSThe carriage of 936 CT and CT+TT genotypes had significantly higher risk of colorectal adenoma (CT vs. CC, OR=2.00, 95% CI: 1.23-3.25, P=0.006; CT+TT vs. CC, OR=2.04, 95% CI:1.28-3.26, P=0.003). 936-T allele carriage had increased risk of colorectal adenoma (OR=1.91, 95% CI:1.25-2.91, P=0.003). The genotypes of 1498 C/T and the frequency of C/T allele showed no differences between healthy persons and patients (P>0.05). In patients with 936 CT+TT and 936-T allele implied a tendency of villous adenoma category (CT+TT vs. CC, OR=2.54, 95% CI:1.12-5.75, P=0.040; T allele vs. C allele, OR=3.08, 95% CI, 1.64-5.80, P=0.001).

CONCLUSIONVEGF 936 C/T polymorphism can influence susceptibility to colorectal adenoma.
