BACKGROUND: Radiofrequency catheter ablation (RFCA) in dog triggers myocardial nerve sprouting and sympathetic hyperinnevation. It is possible that RFCA in humans has the same effect. Nerve growth factor (NGF) is a neurons nurture that supports the survival and differentiation of sympathetic neurons and enhances target innervation. Therefore, it is hypothetic that RFCA can increases plasma NGF concentration in humans.OBJECTIVE: To test the hypothesis that RFCA increases plasma NGF concentration in humans.DESIGN: Self-control experiment.SETTING: Department of Cardiology, Tangdu Hospital, the Fourth Military Medical University of Chinese PLA.PARTICIPANTS: Forty-three patients were selected from the Cardiological Department of Tangdu Hospital, the Fourth Military Medical University of Chinese PLA from January to June 2005, including atrioventricular nodal reentrant tachycardia (AVNRT) (n=18), right-sided accessory pathways (RSAP) (n=13) and left-sided accessory pathways (LSAP) (n=12), 20 males and 23 females, ages 28-65 years, all agreed to participate in the study voluntarily.METHODS: Blood samples were obtained from the peripheral veins before ablation and at 6 hours, 1, 3, 5, 7 days after ablation. The plasma concentration of NGF was determined with enzyme-linked immunosorbent assay (ELISA).MAIN OUTCOME MEASURES: The plasma concentration of NGF was determined with ELISA before RFCA and at 6 hours, 1, 3, 5, 7 days after RFCA in each patient.RESULTS: Total 43 patients who were referred for ablation therapy for AVNRT, RSAP and LSAP were involved in the result analysis without loss. Plasma NGF increased at 6 hours after RFCA. Increased NGF continued to 7 days in the RFCA treated patients. The plasma NGF concentrations at 6 hours, 1, 3, 5, 7 days after RFCA in AVNRT, RSAP and LSAP ablations treated patients were (29.72±7.04), (30.94±5.68),(31.39 ±4.92), (31.06 ±4.56), (29.11 ±4.59), (31.77 ±6.25), (30.69 ±5.10),(31.46±4.96), (30.15±4.01), (30.43±3.14), (31.42±6.75), (31.00±5.20),(32.08±4.62), (30.67±3.71), (29.27±2.75) μg/L, respectively, and all more than that before RFCA [(14.89±2.84), (15.00±2.71), (15.51±2.75) μg/L, P ＜ 0.01]. However, there were no significant differences in the NGF levels at 6 hours, 1, 3, 5 and 7 days after RFCA (P ＞ 0.05). The plasma NGF concentration was not significant different among AVNRT, RSAP and LSAP ablation patients at any given time (P ＞ 0.05). The number of RFCA applications, the procedure time and the total energy have no correlation with NGF concentration at any given time instance.CONCLUSION: RFCA increases plasma NGF concentration in humans and lasts for at least 7 days. The number of RFCA applications, the procedure time and the total energy have no correlation with NGF concentration at any given time instance.

A total of 2 153 adolescents aged from 16 to 18 years old from 7 high schools were enrolled. The prevalence of diabetes mellitus and impaired fasting glucose was 6.13% and 16.12%, respectively. The independent risk factors are obesity or overweight.

This paper reports the results of a study about the segregational stability of a series of pNK289-derived plasmids. The segregational stability in B. subtilis AS1. 1176 was found to be different among these same originated plasmids. The difference in segregational stability was shown not to be related to the sizes or replication patterns of the plasmids, but to have some relation to their copy numbers. As the unstable plasmid pNK219 can be miaintained stably in B. subtilis BD 224, it can be inferred that the host inheritable background could affect the segregational stability of plasmid. These results not only have laid a foundation for finding out some genes related to the stability of pNK289-derived plasmids, but also provided theoretical basis for constructing stable recombinant plasmid in Bacillus.

Objective To enhance the understanding of clinical characteristics and genetic testing of chromosome 4q21/q22 deletion syndrome. Methods Chromosomal microarray analysis was used to detect genetic change in a child with special facial appearance and development delay. Results A 15.26-Mb deletion containing 76 geinges in chromosome 4q21.21q22.2 was identiifed. Thus, this girl was diagnosed as chromosome 4q21/q22 deletion syndrome. Conclusions Chromosome 4q21/q22 deletion syndrome has varied clinical manifestations including typical characteristics (such as absolute or relative macrocephaly, megalencephaly with a characteristic head shape and facial appearance, profound hypotonia, small hands and feet, short limbs, feeding difficulties), mental retardation/severe developmental delay, and other system abnormalities ( such as congenital heart disease, seizure, kidney cysts, etc). The diagnosis of chromosome 4q21/q22 deletion syndrome relies on chromosomal microarray analysis.

OBJECTIVE:To analyze the problems about the prescription review by the monitoring system for rational drug use (PASS 1.6.1.7) and discuss the countermeasures. METHODS:A retrospective method was adopted. A total of 4 942 prescriptions of our hospital in the first quarter of 2015 were selected at random,and reviewed by PASS and the pharmacist respectively. The re-view results were analyzed,and then countermeasures were put forward for the problems found to exist in the software review. RE-SULTS & CONCLUSIONS:The conformity rates of prescriptions which had been determined as acceptable through PASS review and pharmacist review were 81.20% and 97.40% respectively. PASS misjudged 929 (18.80%) rational prescriptions as irrational ones,mainly concerning administration and dosage,simultaneous existence of Western medicine and Chinese patent medicine on one prescription,repeated drug use and use with caution,etc. PASS misjudged 122(2.47%)irrational prescriptions as rational pre-scriptions,mainly concerning administration and dosage,inconformity between diagnosis and drug use,etc. The above-said prob-lem was attributed to imperfect hospital management and insufficient software intelligence. It is suggested that the hospital should strengthen the data maintenance and management of information system and PASS developer should improve software rules to in-crease the accuracy rate of prescription review.

OBJECTIVE:To explore the construction effect of rational drug use monitoring system on the improvement of clini-cal drug use in the hospital. METHODS:The data about the construction of rational drug use monitoring system were collected from our hospital,including pharmacist workstation prescription check(check before prescription/medical order charging to realize warning in advance),clinical pharmacy management system prescription comment(realize prescription/medical order comment after-wards)and adverse drug reaction/adverse drug event(ADR)reporting information platform(realize online ADR reporting)during 2014-2015. The data was analyzed to evaluate the effectiveness of system construction. RESULTS & CONCLUSIONS:There were a total of 3 417 329 prescriptions audited by the pharmacist workstation within 2 years through improving system functions,includ-ing 7 315 prescriptions were returned to doctors to be modified,the percentage of which declined from 0.39% to 0.08%. The pass rate of prescription comment pre-judgment increased from 81.2% to 90.4% in 2015 by clinical pharmacy management system. The valid case number of ADR monitoring and reporting increased from 186 cases to 267 cases,involving all department of our hospi-tal. The construction of rational drug use monitoring system in our hospital can improve the standardization of prescription/medical orders,the level of rational drug use and the case number of ADR,which has achieved the expected results.
