Circulating endothelial cells(CEC)are mature endothelial cells,which have been shed from the vascular cell lining and enter into blood circulation.Rare in healthy individuals,increased CEC in peripheral blood reflects significant vascular damage and dysfunction.Increased CEC have been documented in many human diseases characterized as vascular damage,including different types of tumors.Clinical data suggest that CEC count is a promising tool for monitoring disease activity with potential to assess tumor prognosis and response to treatment.

Objective To observe the effect of scalp acupuncture combined with speech training on language development delay in mental retardation children. Methods 40 cases were divided into 2 groups, 20 cases in each group. The observation group was treated with scalp acupuncture combined with speech training. The control group was treated with speech training. They were assessed with the development quotient (DQ) of adaptability and language of Gesell Developmental Schedules before and 3 months after the treatment. Results DQ of adaptability and language improved after treatment in both groups (P<0.05), and improved more in the observation group than in the control group (P<0.05). Conclusion Scalp acupuncture combined with the speech training is more effective on language development delay in mental retardation children.

Objective To promote the progress in varicella-zoster virus (VZV) immunoglobulin preparation,a rapid microneutralization test ( RMNt) was set up for screening plasmapheresis donations with high titers of special neutralizing antibodies to VZV.Methods With reference to the VZV immunoglobulin (VZIG) preparation standard of FDA and VZIG international unit ( IU) , a screening standard was formulated; the amount of virus was analyzed to determine the optimal conditions for RMNt;screening technology was established and the IU was introduced as quality control ;twenty samples of apheresis plasma and fifteen samples of pooled plasma were diluted at 1∶2 to 1∶256 and tested by RMNt respectively;and the sensitivity of RMNt was also analyzed by the commercial ELISA kit .Results Plasma samples that were diluted at 1∶16 and had a titer more than 0.4 U/ml could be used in the production of VZIG .1500 PFU/ml titers of virus in RMNt pro-duced readable results in plasma screening .Eight apheresis plasma samples tested met the screening standard , but none of the pooled samples tested positive .RMNt had a good linear relationship with ELISA (r=0.895 24,P<0.0001).Conclu-sion The sensitivity, throughput and operability of the established RMNt can be used in the screening of plasma donations as key techniques for the production of VZIG .

Objective To investigate the antibiotic resistance, virulence genes, and sequence types of Enterococcus faecium ( E. faecium) strains isolated from children under 3 years old in Sui county, Henan province. Methods Kirby-Bauer antibiotic testing was performed to analyze the antibiotic sensitivi-ties of E. faecium strains to 15 common antibiotics. PCR analysis was used to detect the virulence genes car-ried by the E. faecium strains. Multilocus sequence typing ( MLST) was performed for the typing of E. faeci-um strains. Results Forty-seven E. faecium strains were isolated from 120 stool samples collected from chil-dren under 3 years old in Sui county, Henan province, of which 95. 7% were antibiotic-resistant strains. Most of the isolated E. faecium strains were resistant to rifampicin, accounting for 91. 5% (43/47) of all isolates, followed by those resistant to erythromycin and tetracycline, which accounted for 68. 1% (32/47). Moreover, high resistance rates to those antibiotics commonly used in clinical treatments of E. faecium infec-tion including β-lactam and aminoglycosides antibiotics were observed. Those strains resistant to more than three kinds of antibiotics belonged to the same clonal complex including 12 strains of clonal complex 17 ( CC17) harboring the virulence gene of hyl. All of the isolated E. faecium strains were susceptible to vanco-mycin, linezolid, chloromycetin and nitrofurantoin. Conclusion The E. faecium strains isolated from chil-dren under 3 years old in Sui county, Henan province were multi-antibiotic resistant. There were drug-resist-ance strains belonging to the CC17 and carrying the virulence gene of hyl.

Objective To investigate the effects of Danzhi Jiangtang Capsule on CXCL9 and IL-8 in type 2 diabetic model rats, and discuss the mechanism in TCM intervention in type 2 diabetes. Methods Fifty male SD rats were randomly divided into 5 groups:normal control group, high-dosage group of Danzhi Jiangtang Capsule, low-dosage group of Danzhi Jiangtang Capsule, pioglitazone group and model group. Normal control group was fed with basal diet, while the other groups were fed with high fat diet. A single intraperitoneal injection of STZ of 35 mg/kg was employed to establish the animal model of diabetes mellitus. When the diabetic rodent model was built, high-dosage group of Danzhi Jiangtang Capsule and low-dosage group of Danzhi Jiangtang Capsule were treated with 1.08 g/(kg?d) and 0.54 g/(kg?d) by gavage, pioglitazone group was treated with 10 mg/(kg?d) by gavage, the blank group and the model group were treated with physiological saline 5 mL/(kg?d) by gavage for 8 weeks. CXCL9, IL-8 and blood glucose, and lipid in serum of rats were determined with double antibody sandwich method. Results Expressions of CXCL9 and IL-8 in model group increased significantly, compared with the normal control group (P<0.05, P<0.01). Expressions of CXCL9 and IL-8 in high and low dosage Danzhi Jiangtang Capsule group significantly decreased, the blood glucose and lipid also decreased, compared with model group (P<0.01). Conclusion Danzhi Jiangtang Capsule has inhibitory effects on the high expression of inflammatory factors in diabetes, and can also lower bloodglucose, and regulate blood lipid.

Objective: To observe the efficacy of unblocking and regulating the Belt Vessel acupuncture method for patients with abdominal obesity in Germany and its influence on the body fat parameters and glycolipids metabolism. Methods: A total of 82 cases of abdominal obesity in Germany were selected. There were two dropout cases in the treatment process. All of the patients received acupuncture at Daimai (GB26), Daheng (SP15), Tianshu (ST25), Zhongwan (CV12), Shuidao (ST28), Waiguan (TE5), and Zulinqi (GB41). The patients received acupuncture therapy once every 2-3 d, 3 times a week. The treatment duration lasted 4 weeks. Before and after treatment, the body mass (BM), waist circumference (WC), abdominal circumference (AC), hip circumference (HC), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and fasting blood glucose (GLU) were measured respectively, and the body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), and body fat rate (BFR) were calculated. Results: After treatment, the total effective rate was 72.5％; the levels of BM, WC, AC, HC, BMI, WHR, WHtR, BFR, TC, LDL-C, and GLU declined significantly compared with those before treatment (P<0.01), while the TG and HDL-C slightly declined, but the differences were statistically insignificant (P>0.05). Conclusion: The unblocking and regulating the Belt Vessel acupuncture method can significantly reduce body fat parameters such as BM, AC, and BFR, and correct the disorders of glucose and lipid metabolism in patients with abdominal obesity in Germany.
