In this study a combination of HRP retrograde tract tracing and immunocytochemistry was employed to investigate the afferent projections of neuropeptide Y(NPY) -and neurotensin (NT)-immunoreactive(ir) neurons in the cervical, thoracic, lumbar and sacral spinal segments to the parabrachial nucleus in the rat. It was demonstrated that the retrogradely labeled neurons were scattered in bilateral laminae I, II, IV, V, VII, gray matter commissure dorsal to the central canal, lateral cervical nucleus and lateral spinal nucleus. The NPY-ir neurons were situated in bilateral lamina I, superficial portion of the lamina II, lateral cervical nucleus and lateral spinal nucleus. The NT-ir cells were seen in bilateral lamina I and lamina II of dorsal horn. In lamina I, lateral cervical nucleus and lateral spinal nucleus a few of NPY-HRP double labelled neurons could be observed. Individuals of NT-HRP double labeled neurons were identified only in lamina I. The results of this study suggest that NPY and NT neurons probably involved in the nociceptive transmission of the spino-parabrachial pathway.

By introducing a mixture of WGA-HRP and HRP or fluorogold into the parabrachial nucleus, the cell origin of the spinoparabrachial projections in the rat have been carefully examined. The labelled neurons were found in bilateral spinal gray matter, lateral spinal nucleus and lateral cervical nucleus with contralateral predominance. They were mainly located in lamina I, lamina II, lamina IV, lamina V and lamina VII of the gray matter and also in the gray matter commissure posterior to the central canal. Comparing the distribution patterns of the projection neurons in the cervical, thoracic, lumbar and sacral segments, we did not find any distinct differences. The fact that the parabrachial nucleus receives a wide extensive projections form the spinal segments suggests that the spino-parabrachial pathways are possibly involved in the transmission of multiple sensory inputs.

Objective To investigate the synergistic effect of calcium channel blocker on cyclosporine-induced gingival overgrowth (GO). Methods 130 renal transplant patients treated with cyclosporine were divided into group A (with calcium channel blocker) and group B (without calcium channel blocker). Demographic, pharmacologic and periodontal data were recorded. The prevalence and severity of GO were compared between the two groups. Three calcium channel blockers, including nifedipine, amlodipine and felodipine, were administered in the patients of group A. The relationships between these three calcium channel blockers and the prevalence of GO were analyzed. Results The patients receiving calcium channel blocker showed significantly higher prevalence of GO (44/73,60 % ) than those without calcium channel blocker (22/57, 39 %) (P＜0. 05). A higher proportion of mild GO (37 %) in group A was also observed than in group B (19 %, P＜0. 05). There were no significant differences in the proportions of moderate and/or severe GO between the two groups (P＞0. 05). Periodontal variables, including plaque index and papilla bleeding index, were significantly higher in GO patients than in those without GO in both two groups (P＜0. 05). In addition, the prevalence of GO in patients receiving nifedipine (77 %) was higher than in those receiving amlodipine (57 %) or felodipine (50 %). Conclusion The combination with calcium channel blocker is a risk factor of cyclosporine-induced GO and the use of nifedipine should be avoided for these at-risk patients.

Objective To evaluate the application effect of clinical nursing pathways in acute myocardial infarction patients by using the Meta-analysis.Methods Published randomized controlled trials (RCT) in acute myocardial infarction patients were searched and screened in CNKI,VIP,Wanfang database under present standards.The quality of the included studies was evaluated by certain standards.The Review Manager 5.0 software was taken for analysis.Results Totally 18 studies including 1877 cases were eligible to the criteria (894 in the experimental group and 983 in the control group) altogether.The Meta-analysis showed there was significant difference between the experimental group and the control group in hospitalization days,patients' satisfaction degree and rate of mastering knowledge.Significant difference existed between the experimental group and the control group in bedridden time,complication rate and the recurrence rate of myocardial infarction.Conclusions Application of clinical nursing pathway in acute myocardial infarction patients can shorten hospitalization days,increase patients' satisfaction degree and rate of mastering knowledge,decrease bedridden time,complication rate and the recurrence rate of myocardial infarction.

Objective To study the repairing effects of nerve growth granule(NGG) on rat common peroneal nerve transection injury.Methods After 50 Sprague-Dawley rats were subjected to nerve suture after transaction,they were randomly divided into 5 groups for daily intragastric administration of drugs:NGG high-dose(5.2g/kg),medium-dose(2.6g/kg),low-dose(1.3g/kg) groups,mecobalamin group(positive control) at 625 ?g/kg,control group(control group control).The drug administration lasted for 4 weeks.Footprint test was performed 2-,3-and 4-weeks after surgery to evaluate toe spread function(TSF).Electrophysiology was performed 4 weeks after operation to determine the compound muscle action potential(CMAP) and nerve action potential(NAP).The number of regenerated myelinated nerve fibers,thickness of myelin sheath and cross sectional area of tibial muscle were measured by histomorphology.Results TSF,amplitude and recovery rate of CMAP and NAP,the number of regenerated myelinated nerve fibers,thickness of myelin sheath and section area of tibial muscle were all increased significantly in a dose-dependent manner compared with the control group.Conclusion NGG contributes to axon growth and myelination,and thus promotes peripheral nerve regeneration in rats with functional recovery.

ObjectiveTo study the occurrence and influence factors of drug-induced injuries of vital organs caused by traditional Chinese medicine injection.MethodsChina Hospital Knowledge Database (CHKD) from 1993-2013 and case reports concerning adverse effects and drug-induced diseases caused by traditional Chinese medicine injection from Wanfang Data Knowledge Service Platformwere retrieved. Indicator systemwasestablished and relevant contentsweresummarized and analyzed.Results34 types of traditional Chinese medicine injectionswereincluded and 699 drug-induced diseasesweresummarized, taking up 53.98% of the total adverse effects. Among them, the top three included in the drug-induced diseaseswere acanthopanax injection, safflower injection and Mailuoning injection. The non-conformance between the traditional Chinese medicine injections in the literature and instructions mainly reflects unreasonable solvent selection, large compatibility concentration and usage and dosage beyond those specified in the instructions. ConclusionThe occurrence of drug-induced injuries of vital organs caused by traditional Chinese medicine injectionis relatively high, drug instructions shall be strictly followed in accordance with requirements during clinical application.
