Objective To investigate the causes of unqualified sputum specimens culturing and put forward the countermeasures.Methods One thousand five hundred and twenty-four sputum specimens from January to December in 2012 were collected as control group and another 768 cultured sputum specimens from January to June in 2013 as the experimental group.The sputum specimens in the control group were analyzed by a designated nurse to find out causes for the unqualified specimens and work out countermeasures.Then the strategies to avoid unqualified specimens were used in the experimental group.Finally, the unqualified rate was compared between the two groups.Result The experimental group was significantly better than the control group before taking the measures for culturing in terms of time for specimen collection, inadequacy in specimens, unprepared oral tract, quality in specimens, sputum collected from deep into lungs(P<0.05).Conclusion The main causes of unqualified specimens included improper choice of time for specimen collection, inadequacy in specimens and unprepared oral tract.Enhanced training to medical staff, health education to patients and standardized flowchart for specimens collection are critical for the improvement of qualified sputum culturing.

The initiation of puberty is associated with the hypothalamus-pituitary-gonadal( HPG) axis. The activation of gonadotropin-releasing hormone( GnRH) is the key factor in the initiation of puberty. The initi-ation of puberty is a complicated process,GnRH is under the influence of many associated neuropeptides. Re-cently,the studies have found that GnIH and Kisspeptin can respectively inhibit and promote the hypothalamus GnRH secretion of mammals,indicating that GnIH and Kisspeptin on regulation of reproductive endocrine axis play very important roles. Therefore,GnIH/GPR147 and Kisspeptin/GPR54 pathways may be closely associated with the initiation of puberty.

Objective To investigate the effects of transplantation of sciatic nerve(SN) and injection of 8-(4-Chlorophenylthio)-cAMP(CPT-cAMP) into the viteous on axotomized retinal ganglion cells(RGCs) in adult hamsters. Methods Twenty adult golden hamsters were ramdomly divided into 4 groups.Optic nerve(ON) was transected and a segment of autologous sciatic nerve(attached graft,AG) was removed and sutured to the proximal stump of ON in regenerating control group(AG group).The animals in experimental groups were further treated with CPT-cAMP injection and/or implantation of a short of segment sciatic nerve(SN) intravitrously.Fluorescent retrograde labeling method and quantitative anatomical techniques were used to measure the number of RGCs. Results 1.In control (AG) retinas,the mean number of regenerating RGCs was 1*!428?284/retina.2.In AG+SN group,the mean number of regenerating RGCs was 2*!220?415/retina.3.In AG+cAMP group,the mean number of regenerating RGCs was 2*!175?364/retina.4.The mean number of regenerating RGCs in AG+cAMP+SN group were 4*!255?820/retina.AG+SN,AG+cAMP groups were significantly different from AG group(P

Objective Use three inhibitors to block three different signaling pathway to explore the mechanisms of 3-isobutyl-1-methylxanthine(IBMX) and 8 (4 Chlorophenylthio) cAMP(CPT-cAMP) on the regeneration of retinal ganglion cells. Method Fluorescent retrogratde tracing method and quantitative anatomical techniques were used to measure the numbers of RGCs in control one,control two group and experiment groups. Results 1^ In control group 1(AG),the mean number of regenerating RGC was 1428??284/retina in 4 weeks after surgery; 2^ In control group 2(AG+IBMX+CPT-cAMP) the mean number of regenerating RGC was 4?917?1 489/retina in 4 weeks after surger; 3^ The mean number of regenerating RGC of experiment groups in 4 weeks after surgery were (1) H89 group(AG+IBMX+cAMP+H89):1?426?320/retina; (2)Wortmannin group(AG+IBMX+cAMP+Wortmannin):4143?1?057/retina; (3)PD98059 group(AG+IBMX+cAMP+PD98059):4?154?965/retina. Conclusion The promoting effects of IBMX and CPT-cAMP on regeneration of RGCs can be interrupted by H89 and can't be blocked by wortmannin and PD98059.
