Objective To explore the reasons and the treatment counter-measures for secondary intracranial hemorrhage happens in the intracranial tumor craniotomy. Methods Retrospectively analyzed the clinical data of 15 patients with intracranial tumor who suffered secondary intracranial hemorrhage intraoperation. Summarized the tumor characteristics and the situation of corresponding vessels confined by second operation. Results In these 15 cases,the rank of course of disease was 6.5 months to 2 years, mean 1.2 years. The size of the tumor was big with diameter 4.62 ～5. 82cm,mean 5. 12cm,and the tumor was deep surrounding by large range edema,which led to intracranial hypertension. The emissary vein,bridging vein and cortical draining vein were considered as the corresponding vessels for ' secondary intracranial hemorrhage during the second operation carried out for all 15 cases. There wsa no death cases in this research and all patients recovered the nomal ability for self-caring after 3 months following up. Conclusion Sudden drawdown of intracranial pressure and perfusion pressure breakthrough of local vessels had relationship with secondary intracranial hemorrhage during craniotomy for intracranial tumor. Accurate judgement for the occurrence of secondary intracranial hemorrhage intra-operation and quickly taking the effective corresponding measures was the important strategy for prognosis improving for these patients.

Chloroplast-based expression system is promising for the hyper-expression of plant-derived recombinant therapeutic proteins and vaccines. To verify the feasibility of obtaining high-level expression of the SARS subunit vaccine and to provide a suitable plant-derived vaccine production platform against the severe acute respiratory syndrome coronavirus (SARS-CoV), a 193-amino acid fragment of SARS CoV spike protein receptor-binding domain (RBD), fused with the peptide vector cholera toxin B subunit (CTB), was expressed in tobacco chloroplasts. Codon-optimized CTB-RBD sequence was integrated into the chloroplast genome and homoplasmy was obtained, as confirmed by PCR and Southern blot analysis. Western blot showed expression of the recombinant fusion protein mostly in soluble monomeric form. Quantification of the recombinant fusion protein CTB-RBD was conducted by ELISA analysis from the transplastomic leaves at different developmental stages, attachment positions and time points in a day and the different expression levels of the CTB-RBD were observed with the highest expression of 10.2% total soluble protein obtained from mature transplastomic leaves. Taken together, our results demonstrate the feasibility of highly expressing SARS subunit vaccine RBD, indicating its potential in subsequent development of a plant-derived recombinant subunit vaccine and reagents production for antibody detection in SARS serological tests.

Objective: To explore the association between circadian rhythm with depressive and anxiety symptoms of college students in Jinzhou City, to provide a theoretical basis for targeted depression and anxiety prevention among college students. Methods: A total of 1 938 college students were selected by convenient sampling method from November to December 2020 for questionnaire survey. The relationship between circadian rhythm and depression and anxiety symptoms was analyzed by using questionnaire,survey including Self Rating Depression Scale (SDS), Self Rating Anxiety Scale (SAS) and Munich Chronotype Questionnaire (MCTQ). Results: There were significant differences in the distribution of depressive symptoms in different majors, smoking, drinking and physical exercise ( χ 2=46.80, 5.88, 5.76, 12.23, P <0.05). There were significant differences in the distribution of anxiety symptoms in different majors, smoking and drinking ( χ 2=9.41, 5.80, 5.56, P <0.05). Stratified analysis showed that the depressive symptoms of different chronotype were statistically varied by age, gender, professional, grade, registered residence, body mass index, smoking, drinking, and sports( χ 2=8.16, 14.42, 12.25, 6.19, 10.99, 15.29, 17.41, 15.63, 7.47, 9.59, 10.51 , P <0.05). The anxiety symptoms of different chronotype were statistically different in age (21 years) and smoking (no), ( χ 2= 8.34 , 7.16, P <0.05). Spearman rank correlation showed that the corrected Mid sleep on Free Days Corrected for Sleep Debt on Work Days (MSFsc) was positively correlated with the standard scores of depression and anxiety ( r s=0.10, 0.09), and social jet lag was positively correlated with the standard scores of depression and anxiety ( r s=0.09, 0.05)( P <0.05). After controlling for age, major, smoking and drinking, binary Logistic regression showed that mean sleep length was inversely correlated with depressive symptoms ( OR =0.82), and weekly insomnia frequency was positively correlated with depressive symptoms ( OR=1.14 ).Early type and intermediate type of chronotypes were negatively correlated with depression ( OR =0.66,0.57). Intermediate type of chronotype was negatively correlated with anxiety symptoms ( OR =0.65). Conclusion Circadian rhythm is related to depressive and anxiety symptoms,among which the average sleep length, early rise and intermediate sleep patterns are negatively related to depression symptoms, and intermediate sleep patterns and anxiety symptoms, suggesting that circadian rhythm disorder may affect depression and anxiety symptoms.
