Journal of Shanghai Jiaotong University(Medical Science) 2020;40(1):18-21
Objective:To explore the relationship between rs3758391 polymorphism of SIRT1 gene and depressive symptoms, and to further understand the role of SIRT1 gene in major depressive disorder. Methods:A total of 323 patients with major depressive disorder were retrospectively collected from the Jinhua Second Hospital, Wenzhou Kangning Hospital and Shanghai Mental Health Center, Shanghai Jiao Tong University School of Medicine. A total of 347 healthy subjects were also recruited. Depressive symptoms were evaluated by using the Hamilton Depression Scale (HAMD), and rs3758391 polymorphism was genotyped by using the TaqMan SNP genotyping Assay. The effect of rs3758391 polymorphism on the expression of SIRT1 mRNA in brain was analyzed by BRAINEAS database, and the difference of depressive symptom severity among three genotypes at rs3758391 polymorphism was compared by multivariate analysis of variance. Results:The frequencies of C and T alleles of rs3758391 polymorphism in SIRT1 gene were 18.7% and 81.3% in the case group, and 14.3% and 85.7% in the control group, respectively. The allelic distribution frequencies between the two groups were significantly different (χ2=4.86, P=0.03). There were significant differences in mood, cognitive impairment and HAMD scores among patients with different genotypes of rs3758391 polymorphism (P<0.05). The results of eQTL analysis showed that rs3758391 polymorphism was significantly correlated with the expression of SIRT1 gene in occipital cortex (OCTX) (P=0.003). Conclusion:rs3758391 polymorphism of SIRT1 gene may be a risk factor for major depressive disorder in Chinese Han population, and is associated with the severity of depressive symptoms, especially with emotional symptoms and cognitive impairment.

Objective: To understand the effect of dobutamine on the integrated backscatter of myocardium. Methods: Nineteen open-chest dogs were detected by HP Sonos 5500 with S8 transducer, and the WT, AIBS and CVIB were measured before and after the dobutamine stress. Results: During the dobutamine stress, following the increase of WT, the transmural, subepicardial and subendocardial CVIB all increased. And the increase of subepicardial CVIB was greater than that of subendocardial CVIB, leading to the decrease of TGI. But the AIBS didn't change significantly in the whole process. Conclusion: Dobutamine can enhance myocardium CVIB but has no obvious infleunce on AIBS.

Objective To evaluate the surgical treatment of carotid artery stenosis. MethodAccording to the level and degree of the stenosis, different operations were performed on 120 patients who suffered from the extracranial carotid stenosis. Treatment result was retrospectively reviewed. ResultSurgery was successful in all the patients. We performed carotid endarterectomy on 111 cases and other operations on 9 cases. The incidence of postoperative complications was low, especially for carotid endarterectomy. ConclusionCarotid endarterectomy is still the main therapy for the treatment of carotid artery stenosis with a satisfactory result.

Objective To explore the application of submental ultrasonongraphy (SUS) in the assessment of oropharyngeal swallowing disorders in children with cerebral palsy.Methods Seventeen children with cerebral palsy and oropharyngeal swallowing difficulties (7 on nasal feeding,10 on oral feeding) constituted the treatment group while 20 normal counterparts formed the control group.SUS was applied to measure any changes in the thickness of the tongue muscle and the range of hyoid bone displacement when they swallowed 5 ml of water.The results were compared with those assessed using the functional oral intake scale to decide the best cut-off point for detecting tube-feeding-dependent dysphagia.The intraclass correlation coefficient (ICC) of the 20 children in the control group was calculated to evaluate the intra-rater and inter-rater reliability of SUS.Results The average tongue muscle thickness change and hyoid bone displacement amplitude of the children on nasal feeding were significantly smaller than those of the children without nasal feeding and the normal children.The best cut-off point for the tongue muscle thickness change data was 1.0 cm,and that of the hyoid bone displacement amplitude was 1.5 cm.All of the ICCs were above 0.4,indicating good intra-rater and inter-rater reliability for the SUS examination.Conclusion Submental ultrasonongraphy can help assess the swallowing function of children with oropharyngeal swallowing disorders.

The killing effects of herpes simplex virus thymidine kinase gene/ganciclovir (HSV-tk/GCV) approach by the addition of several commonly clinical chemotherapeutic agents on hormone refractory prostate cancer (HRPC) cells PC-3m were investigated. After transferring of the HSV-tk gene into PC-3m cells, mRNA and protein expression of HSV-tk was detected by reverse-transcript polymerase chain reaction (RT-PCR) and strept avidin-biotin complex (SABC) immunohistochemical method. The killing effect of GCV, cisplatin (CDDP), etoposide (VP-16), vincristine (VCR), methotrexate (MTX), 5-fluorouracil (5-Fu), and suramin on PC-3m cells was evaluated by morphological assessment analysis, trypan blue exclusion assay and MTT assay respectively. Additionally, the cooperative effect of HSV-tk/GCV system combined with the above agents on the target cancer cells was determined by MTT. Furthermore, apoptosis and necrosis induced by GCV plus 5-Fu or suramin was analyzed by flow cytometry (FCM). The results showed that that there was HSV-tk mRNA and protein expression in pDR2-tk plasmid transduced PC-3m cell. Combination of GCV with VP-16, VCR, 5-Fu or suramin led to an enhanced cellular killing effect, but with CDDP resulted in a reduced one and with MTX in an approximate one. FCM revealed that synergistic use of GCV and 5-fu or suramin resulted in a rather large proportion of apoptosis and necrosis with the apoptosis index being 36.38% and 35.51%, and the proportion of necrosis being 33.05% and 28.87%, respectively. In conclusion, HSV-tk/CGV approach by addition of certain clinical available chemotherapeutic drugs brings on statistically significant enhanced cell killing over single-agent treatment. Our results highlight the potential for such new combination therapies for future treatments of HRPC.

Connexin-43 (Cx43) expression in prostate cancer (PCa) cells and the potency of gap junctional intercellular communication (GJIC) in the cells were investigated, with an attempt to elucidate the reason why the so-called "bystander effect" mediated by thymidine kinase (TK) suicide gene therapy on PCa cells is not of significance and to explore the role of GJIC in PCa carcinogenesis. mRNA and protein expression of Cx43 in a PCa cell line PC-3m was detected by reverse-transcription polymerase chain reaction (RT-PCR) and strapt-avidin-biotin-enzyme complex (SABC) immunohistochemical staining, and inherent GJIC of PC-3m cells was assayed by scrape-loading and dye transfer (SLDT) assay. The expression of Cx43 in human normal and malignant prostate tissues was determined by SABC immunohistochemistry as well. It was found that Cx43 mRNA and protein expression in PC-3m cells was slightly reduced as compared with positive controls and the location of Cx43 protein was aberrant in cytoplasm rather than on membrane. Assessment of paraffin sections demonstrated that the expression of Cx43 protein in PCa cells was abnormally located and markedly diminished as compared with normal prostatic epithelial ones, displaying a negative correlation to the pathological grade (chi2=4.025, P<0.05). Additionally, capacity of inherent GJIC in PC-3m cells was disrupted, which was semi-quantified as (+) or (-). It was indicated that both down-regulated expression of Cx43 mRNA and aberrant location of Cx43 protein participated in the mechanisms leading to deficient GJIC in PC-3m cells. Lack of efficient GJIC is a molecular event, which may contribute not only to limited extent of "bystander effect", but also to initiation and progression of prostatic neoplasm.
