ABSTRACT
Objective To evaluate the effect and mechanism of ginkgolide injection combined with edaravone on acute cerebral infarction.Methods 120 acute cerebral infarction patients were divided into observation group and control group,60 cases in each group.The control group was treated with edaravone,and the observation group was treated with ginkgolide injection combined with edaravone.The neuron specific enolase (NSE),S100β,tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6),C reactive protein (CRP),National Institutes of Health stroke scale(NIHSS) and clinical efficacy were compared between the two groups.Results After treatment,the levels of NSE,S100β,CRP,IL-6 and TNF-α of the observation group were (7.1 ± 1.5) μg/L,(0.2 ±0.1) μg/L,(14.5 ± 3.7) mg/L,(20.9 ± 5.3) ng/L and (11.2 ± 3.0)μg/L,respectively,which of the control group were (8.9 ± 2.0) μg/L,(0.4 ± 0.2) μg/L,(21.3 ± 4.2) mg/L,(29.7 ± 3.2) ng/L and (18.8 ± 3.6) μg/L,respectively,those of the observation group were significantly lower than comrol group (t =2.898,2.894,3.012,2.998,3.025,all P ＜0.05).After treatment for 7d and 14d,the NIHSS scores of the observation group were (11.8 ± 3.0) points and (7.3 ±2.2) points,respectively,which of the control group were (15.2 ± 3.9) points and (10.5 ± 3.0) points,respectively,the observation group were significantly lower than control group(t =2.984,3.037,all P ＜ 0.05).The clinical efficacy of the observation group was significantly better than that of the control group (83.3 ％ vs.61.7％) (x2 =7.064,P ＜0.05).Conclusion Ginkgolide injection combined with edaravone in the treatment of acute cerebral infarction caninhibit inflammation reaction,alleviate nerve function damage,its effect is better than edaravone.
ABSTRACT
Objective To describe the current situation of pre-hospital delay and health belief in patients with colorectal cancer and explore the relationship between them. Methods With convenient sampling methods,totally 385 patients with colorectal cancer were recruited from January to June 2016. Patients with colorectal cancer were investigated using a general data survey questionnaire, visit situation questionnaire and the Champion Health Belief Model Scale. Results The median pre-hospital delay time was 3.00 months.The rate of pre-hospital delay was 43.1%(166/385). The score of the overall health belief was (119.52 ± 12.62) points. The two dimensions of"perceived susceptibility and perceived severity" scored lower, and the two dimensions of "health motivation and perceived therapeutic benefits" scored higher. The health belief was negatively correlated with the pre- hospital delay among colorectal cancer patients (r=- 0.737, P<0.01). Conclusions Pre-hospital delay occurred among patients with colorectal cancer is severe. Patients with a higher level of health belief have shorter pre-hospital delay.It′s important to improve the level of health belief of"perceived susceptibility and perceived severity"and reduce the time of pre-hospital delay to improve outcomes in patients with colorectal cancer.
ABSTRACT
Objective To explore the dynamic responses of Sertoli cells to depletion of spermatogonial stem cells by busulfan.Methods After intraperitoneal injection of 15, 30 or 44 mg/kg busulfan to mice, the spermatogenesis and the expression of GDNF, PLZF, Nanog and GFRɑ1 mRNA were assessed by real-time quantitative PCR at 5 and 28 days after the busulfan treatment.Results Glial cell line-derived neutrophic factor ( GDNF ) was significantly increased and showed a dose-dependent trend at 5 days after busulfan treatment, but no significant difference was seen in the expression of promyelocytic leukemia zinc finger(PLZF) and GDNF family receptorα-1(GFRα1).The testicular histology also appeared no significant difference at 5 days after busulfan treatment.At 28 days after busulfan treatment, the relative expression lev-els of GDNF, PLZF, Nanog and GFRɑ1 mRNA were drastically increased.Morphological observation showed that spermat-ogenesis damages became even more severe as the busulfan dose increased.Conclusions Sertoli cell response to the de-pletion of spermatogonia occurs as early as the fifth day after busulfan treatment.Production of GDNF in Sertoli cells shows a compensatory increase, which may stimulate spermatogonial stem cells to accelerate their self-renewal, reflected by the enhancing expression of Nanog and PLZF, and ultimately promote the restoration of spermatogenesis.
