1.itative Research of Occupational Injury Experiences of Laboratory Animal Workers
Journal of Zhejiang Chinese Medical University 2014;(8):1027-1030
Objective] To discuss the inner experiences of occupational injury of laboratory animal workers, and provide basis for conducting targeted occupational protective education and health management. [Methods] The phenomenological methodology was used in the study. 12 laboratory animal workers were participated in non-structured interview regarding the experiences of occupational injury. [Results] 3 themes were found including:category of occupational injury(physical injury, chemical injury, biological injury); emotional experiences of occupational injury(fears and concerns, helplessness and self-abasement); help most needed(more attention, knowledge supports, advanced and convenient protective equipment and hardware facilities). [Conclusion] Management of experimental animal industry should lay great emphasis on occupational health and protection of laboratory animal workers, increase both financial and material resources, and enhance occupational protection education, in order to maximize bad physical and psychological effects from occupational injury.

Immunohistochemical method was used to investigate the morphology and distribution of the oxytocin immunoreactive (OXT-ir) neurons and their dendrites in the subependymal plexus (SEP) around the third ventricle (OXT-SEP). The OXT-ir neurons were of magnocellular neurosecretory type which often intercalated between the ependymal cells, their dendrites were generally long and straight and mostly paralleled to or traveled within the ependyma,some of them could protrude into the ventricle, and most of them appeared heavily vacuous and have a strong tendency of grouping into fascicles. The plexus was composed of dorsal and ventral parts, the former corresponding to the extent of the magnocellular paraventricular nuclei and was extensive and dense, the dendrites were well organized; the latter was more sparse. The cell bodies and dendrites within and between different parts might mix or contact with each other. The functional significance of the plexus is discussed.

Objective To explore the value of craniocerebral CT angiography(CTA) to evaluate the prognosis in patients with acute cerebral infarction(ACI).Methods Craniocerebral CTA were performed in 70 patients with ACI at ≤6 h after onset.National Institutes of Health Stroke Scale(NIHSS) score and modeled Rank Scale(mRS) score were investigated at admission,discharge.Results There were 38 patients with visible occlusion on CTA and 32 patients with normal CTA.The patients with vessel occlusion on CTA had significantly worse discharge scores of NIHSS(P0.05).But for patients with vessel occlusion,the ratio of good prognosis in patients received thrombolytic treatment was higher than that of excluded thrombolysis(58.8% vs 31.8%;P

Objective:To optimize the preparation technology of compound sodium lactate injections for the improvement of clari-ty. Methods:The orthogonal test was adopted to screen the best preparation conditions using four influencing factors including the de-carburization temperature of the concentrated solution (A), pH value of the concentrated solution (B), decarburization time of the concentrated solution ( C) and the filling temperature of the injections ( D) with 3 levels for each, and the clarity of the injections as the index. Results:The best preparation conditions were as follows:the decarburization temperature was 60℃, pH value of the con-centrated solution was 6. 5, the decarburization time was 20minute and the filling temperature was 50℃. Conclusion: The optimal process can improve the clarity of compound sodium lactate injections.

ObjectiveTo evaluate the value of National Institute of Health Stroke Scale (NIHSS) combined with CT angiography(CTA) to predict the clinical outcome of acute ischemic stroke patients at ultra-early stage.Methods70 patients with acute ischemic stroke underwent brain CTA within 6 hours from symptom onset and were divided into two groups according to NNIHSS score, and clinical outcome was compared between two groups.ResultsThere were 38 patients with arterial occlusion on CTA and 32 patients with normal CTA. The percentage of occlusion on CTA for patients presenting with more severe neurological deficits was higher than those patients with slight to moderate deficits. The patients with occlusion on CTA and presenting with more severe deficits had a poor clinical outcome (P<0.01). 78% of patients with normal angiograms had good outcome, only 44.7% patients with arterial occlusion had a good clinical outcome(P<0.05). Both CTA evidence of vessel occlusion and admission NIHSS score correlated with clinical outcome measured by discharge NIHSS score(r=0.25, P=0.04 and r=0.73, P=0.000 respectively). The sensitivity and specificity for predicting clinical outcome by using the NIHSS score alone was 56.65% and 85.29%, and positive predictive value (PPV+) was 80.00%. There was a sensitivity of 63.89%, a specificity of 73.53%, a PPV+ of 71.88% if CTA showed vessel obstruction. If NIHSS scores combined with CTA to predict clinical outcome, the result showed a sensitivity of 70.11%, a specificity of 91.18%, a PPV+ of 88.00%.ConclusionThose patients with vessel occlusion on CTA appear to have a worse clinical outcome. NIHSS combining with CTA may increase specificity for judging prognosis and guide treatment.

Objective To compare the efficacy and safety of half-dose verteporfin and half-fluence photodynamic therapy in chronic central serous chorioretinopathy (CSC).Methods The medical records of 42 patients (42 eyes) with chronic CSC were retrospectively reviewed.According to the difference of drug dose and laser parameters in the course of PDT,the patients were divided into two groups:half-dose group and half-fluence group.Half-dose group:22 patients (22 eyes) received half-dose verteporfin(3 mg· m-2)and standard PDT(83 s,50 J · cm-2).Half-fluence group:20 patients (20 eyes) received full-dose verteporfin (6 mg · m-2) and half-fluence PDT (42 s,25 J · cm-2).Patients were followed up at 1 month,3 months,6 months after PDT.The outcome measures was the proportion of eyes with complete resolution of subretinal fluid(SRF),the changes in best corrected visual acuity (BCVA) and central retinal thickness(CMT).Results At 6 months after PDT,22 eyes(100%) that received half-dose PDT showed complete resolution of SRF,19 eyes(95%)that received half-fulence PDT showed complete resolution of SRF.There was no statistical difference between two groups (P > 0.05).At 6 months after PDT,the mean BCVA improved 7.2 letters in half-dose group and 6.7 letters in half-fluence group.There was no statistical difference compared with the improvement of BCVA between two groups(P > 0.05).In half-dose group,mean baseline central retinal thickness was (351 ± 90) μm,which was decreased to (178 ±55) μm after 6 months,respectively (P < 0.05).In half-fluence group,mean baseline central retinal thickness was (322 ± 96) μm,which was decreased to (181 ± 47) μm after 6 months,respectively (P < 0.05).None of the patients developed retinal pigment epithelium atrophy and CNV.Conclusion Half-dose verteporfm PDT and half-fluence PDT are effective and safe in the treatment of chronic CSC.
