Phosphodiesterase-4 ( PDE4 ) has been one of the most popular drug targets during recent years due to its critical role in the control of intracellular cyclic adenosine monophos-phate ( cAMP ) concentration and downstream signal transduc-tion. PDE4 is widely distributed in the central nervous system ( CNS) with different expression levels of its four subtypes. Re-cent data indicate that altered PDE4 expression and/or activity is relevant to multiple CNS disorders, such as depression, memory deficiency, drug dependence, and neural lesion. Selective PDE4 inhibitors exhibit therapeutic effects on these disorders and might be a promising pharmacotherapy. The paper highlights recent re-search progress in the roles of PDE4 in CNS function, and dis-cusses the prospects of PDE4 as a novel therapeutic target for CNS disorders.

Objective To explore the clinical utility of fluorescence in situ hybridization (FISH) urine test as a non-invasive method for diagnosing the upper urinary tract urothelial carcinoma (UUTUC).Methods Urine specimens from 30 consecutive patients with UUTUC were analyzed by means of FISH and cytology.Ultrasonic and CT were also used to analyze urine specimens from the study group.Urine specimens from 30 patients with other diseases were also analyzed by means of FISH and cytology in order to compare the specificity.Results The sensitivities of FISH,cytology,CT and ultrasonic were 87％,37％,90％ and 43％.The specificity of FISH and cytology were 97％ and 93％.The sensitivity between FISH and MMCT were compared and they were not statistically significantly superior to ultrasonic and cytology.FISH and cytology were compared and no specific statistical significance was found.The positive and negative predictive value for FISH was 96％ and 88％.For cytology it was 85％ and 60％.Conclusions FISH analysis is a useful ancillary test in the detection of UT-TCC with excellent sensitivity and specificity.It provides a more reliable and less invasive approach to diagnosis and postoperative follow-up for UT-TCC.

Objective To analyze the application value of the rapid testing for influenza during 2007-2008 flu season at fever clinic in Beijing Chaoyang hospital Methods 500 patients with diagnosis of influenza-like illness were prospectively enrolled. Pharyngeal swabs were collected for influenza viral culture and rapid testing for influenza. Demographic characteristics, age, symptoms, lab tests, symptom recovery time and medical expense were also collected. The sensitivity, specificity, positive predictive value and negative predictive value for rapid testing were analyzed. Results A total of 500 patients were enrolled between Dec 2007 and March 2008. Among them 498 cases were used for analysis. Influenza B was most common by virus culture methed(n=208,41.8%) ,followed by influenza A (n=51,10.2%). The average age was 35, and the ratio of male to female was 1.47:1. Compared with the group of positive culture, patients with influenza were more likely to get cough, sore throat, and nasal congestion (t=13.728, 4.014and 4.720,P<0.001 or 0.05, respectively). A total of 260 cases were subjected to rapid testing, Among them 18 cases were influenza A positive and 132 cases were influenza B positive. The rapid testing had a sensitivity of 77.1 % and a specificity of 70.1%. The positive predictive value was 78.6% and the negative predictive value was 68.2%. The rapid testing had enhanced the proportion of anti-viral treatment from 0 to 26% and reduced the proportion of antibiotic use from 63.4% to 20. 7%. Conclusions Influenza B is the most predominant pathogen during 2007-2008 flu season among patients with influenza-like illness in Beijing. The rapid testing with high sensitivity and specificity provides guidance on clinical practice.

AIM:To investigate the effects of human induced pluripotent stem cell-derived exosomes (hiPSC-exo) on cell viability, capillary-like structure formation , and senescence in endothelial cells exposed to high glucose .METHODS: Exosomes were isolated from the conditional medium of hiPSCs and confirmed by transmission electron microscopy , nanoparticle tracking analysis , and Western blot analysis using Alix and CD63 as markers.hiPSC-exo were labeled with PKH26 for tracking.Cultured HUVECs were treated with high glucose (33 mmol/L) with or without hiPSC-exo (20 mg/L) for 48 h, and cell viability, capillary tube formation, and senescence were assessed .RESULTS:hiPSC-exo showed a typical cup shape and could be taken up by human umbilical vascular endothelial cells (HUVECs) in a concentration-dependent manner.When exposed to high glucose, viability and tube formation in HUVECs was signifi-cantly reduced, whereas the proportion of senescent cells was higher compared to that in control HUVECs (P<0.01).Furthermore, hiPSC-exo restored cell viability and capillary-like structure formation , and reduced senescence in HUVECs exposed to high glucose (P<0.01).However, hiPSC-exo had minimal effects on normal HUVECs.Therefore, stem cell-derived exosomes can promote cell proliferation, enhance capillary-like structure formation , and reduce senescence in endothelial cells exposed to high glucose . CONCLUSION:Our study highlights the role of exosomes derived from hiPSC and may provide a new strategy for maintaining vascular health, preventing vascular aging , and avoiding pathological vascular remodeling that occurs in many diseases .
