Chinese Journal of Biologicals 2023;36(9):1143-1148
Membrane fusion is essential for all life activities of eukaryotes and the fusion process requires the interaction of different vesicular transporters,which are highly conserved in eukaryotes,to coordinate specifically and facilitate the fusion of different biofilms. Vesicle associated membrane protein 8(VAMP8)mainly locates in vesicular as well as lysosomal membranes,and plays a vital role in the fusion of many different biofilms. This paper focused on the molecular structure,transcriptional regulation,post-translational modification and biological function of VAMP8 as well as the research progress on its correlation with human diseases,so as to provide new ideas for the treatment of related diseases and the development of effective therapeutics targeting VAMP8.
4.Relationship among Social Support Coping Style and Mental Health on University Librarians
Chinese Journal of Rehabilitation Theory and Practice 2006;12(5):449-451
ObjectiveTo investigate the relationship among social support,coping style and mental health on university librarians.Methods421 librarians were assessed with the symptom checklist 90 (SCL-90),social support rating scale (SSRS) and simplified coping style questionnaire (SCSQ) in 2005. ResultsSome factor of SCL-90 negatively correlated with utility percentage of social support(P<0.05), and positively correlated with passive coping style(P<0.05). Except utility percentage,the other three factors of social support showed significant difference among different academic titles (P<0.05), and it was significant different (P<0.05) on passive coping factor among them. The score of social support improved with ages except for utility percentage (P<0.05).On positive coping factor but not negative, there were significant difference among different age groups(P<0.05). ConclusionThe social support and coping style obviously correlate with the mental health of university librarians.
5.Clinical analysis of serotretine combined with metformin in the treatment of senile diabetic patients with sulfonylurea failure
Chinese Journal of Biochemical Pharmaceutics 2017;37(7):296-298
Objective To investigate the clinical effect of sitagliptin combined with metformin in the treatment of sulfonylurea-deficient elderly patients with diabetes mellitus.Methods Sixty patients with diabetes mellitus were enrolled in our hospital from January 2013 to December 2016.The patients were divided into observation group(30 cases) and control group(30 cases) according to the random number method.The patients in the observation group were treated with sitagliptin and metformin.The patients in the control group were treated with gemcitabine, and the clinical treatment effect, fasting blood glucose, postprandial blood glucose, glycosylated hemoglobin, fasting C peptide and postprandial 2hC peptide Level of statistical comparison.Results The clinical effect of the observation group was significantly higher than that of the control group.Before and after treatment, the fasting blood glucose, 2h postprandial blood glucose, glycosylated hemoglobin, fasting C peptide and postprandial 2hC peptide level were not significantly different After fasting blood glucose, 2h postprandial blood glucose and glycosylated hemoglobin levels were significantly lower than before treatment, after treatment of fasting C peptide and postprandial 2hC peptide levels were significantly higher than before treatment.Conclusion The clinical efficacy of serotretine combined with metformin in the treatment of elderly patients with diabetes mellitus is similar to that of Yuxing, and the combination is more convenient and more suitable for clinical treatment.It is worthy to be popularized and applied in clinical practice.
6.Effects of photodynamic therapy on microvessels and vascular endothelial growth factor expression in transplanted mouse Heps liver carcinoma
Journal of Medical Postgraduates 2003;0(04):-
Objective: Hitherto there has been no report on the changes of microvessels and the expression of angiogenic factors after photodynamic therapy(PDT) of liver carcinoma.The purpose of this study was to investigate the effect of PDT on the microvessels and the expression of vascular endothelial growth factors(VEGF) in tumor cells. Methods: The mice models subcutaneously transplanted with Heps liver carcinoma were randomly divided into a PDT group(n= 28) and a control group(n= 28).The dynamic changes of the microvessels and VEGF expression in the tumor cells were observed at 2,6,24 and 72 h after PDT by H-E and immunohistochemical staining.Results: Progressive changes were seen in the tumor microvessels at the four time points after PDT,including dilatation,blood stasis,hypostasis,hemorrhage,and angiolysis.Compared with the control group,the microvessel density of the tumors was reduced significantly(P
7.Dysphagia after Traumatic Brain Injury (review)
Chinese Journal of Rehabilitation Theory and Practice 2012;18(8):740-742
The incidence of swallowing disorder is high in previous research both in oral and pharyngeal stage, and there are many related factors contributing to the assessment of swallowing function. This article reviewed the research progress of dysphagia after traumatic brain injury (TBI) from epidemiology, assessment methods, characteristics, risk factors, therapeutic strategies and clinical outcome。
9.Clinical significance of cerebrovascular hemodynamic index with ultrasound in silent cerebral infarction
Chinese Journal of Cerebrovascular Diseases 2015;(6):292-296
Objective Toobservetheclinicalsignificanceofcerebrovascularhemodynamicindex (CVHI)inthepatientswithsilentcerebralinfarction.Methods Atotalof180patientsperformed cerebrovascular hemodynamics with ultrasound and head MRI examinations were enrolled retrospectively. They were divided into three groups:60 patients with silent cerebral infraction (SCI)were used as a SCI group,60 age-,sex- and previous medical history-matched high risk patients with cerebrovascular disease were used as a cerebrovascular disease risk factor (CV-HRF)group,and 60 healthy subjects were used as a normal control group over the same period. Cerebrovascular function detector was used to collect CVHI at the bilateral carotid arteries. The CVHI features of the 3 groups were analyzed and compared. Results Comparedwiththecontrolgroup,thereweresignificantchangesinvariousindexesofcerebral vascular hemodynamics in the SCI group and the CV-HRF group. The indexes of reflecting the cerebral blood supply state included significantly decreased mean blood flow,mean flow velocity,maximum flow velocity,and minimum flow velocity (P<0. 05);the indexes reflecting vascular elastic properties and resistance status included the increased pulse wave velocity,characteristic impedance,peripheral resistance,and dynamic resistance (P<0. 05);the indexes reflecting cerebral microcirculation included significantly increased critical pressure and decreased differential pressure (P<0. 05);the total score of cerebrovascular function was also decreased significantly,they were 44 ± 9,51 ± 5,and 85 ± 7,respectively (P<0. 05);there were significance differences in the distribution of total score amongthe3groups(P<0.05).Conclusion Thehigh-riskpatientswithsilentcerebralinfarction and cerebrovascular disease have the CVHI changes. The total integrated value of cerebrovascular function declined,and the former is more obvious.
10.Study of oxalate degraded ability of Lactic acid bacteria of marketable yoghurt in vivo culture
Chinese Journal of Urology 2006;0(S1):-
Objective To know the ability of degrading oxalate of three species of Lactic acid bacterium and their mixing bacteria coming from yoghurt in vivo culture broth. Methods Identifying the species of Lactic acid bacteria obtained from 6 brands of yoghurt.Three species of bacterium and their mixture was cultured separately for 72 h in MRS broth which contained three different concentration of ammonium oxalate,and the broth without inoculum of bacteria was prepared as a control.The concentration of ammonium oxalate in culture were detected. Results Three species of Lactic acid bacteria (L.bulgaria,L.acidophilus and L.thermophilus) were detected in every band of yoghurt.After 72 h incubation,the concentration of oxalate in all the broth containing bacteria was lower than that in the control ones.L.acidophilus showed the best degrading activity,and in the presence of ammonium oxalate 5 mmol/L,the 11.0% of oxalate was degraded by the bacteria.The higher concentration of oxalate was,the more the amount of oxalate degraded was,but the lower the percent of degrading was. Conclusions All the species coming from yoghurt have the ablitiy of oxalate degrading which become greater as the increasing of the concentration of oxalate in culture.
