ABSTRACT
Objective@#To explore the role of mobile phone addiction and anxiety symptoms in the relationship between childhood psychological abuse and depressive symptoms among college students, in order to provide a basis for mental health promotion.@*Methods@#From February to May 2023, a stratified random sampling method was used to select 1 799 freshmen to juniors from a university in Wuhu City, Anhui Province. The questionnaire survey was conducted using the 2-item Patient Health Questionnaire (PHQ-2), Child Psychological Maltreatment Scale (CPMS), Mobile Phone Addiction Tendency Scale (MPATS), 2-item General Anxiety Disorder (GAD-2). Correlations among each variable were analyzed, and the chain mediating effect of mobile phone addiction and anxiety symptoms was explored.@*Results@#The detection rate of depressive symptoms among college students was 9.7%, and the positive detection rate of childhood psychological abuse was 28.6%. Depressive symptoms were positively correlated with childhood psychological abuse, mobile phone addiction and anxiety symptoms ( r =0.28, 0.32, 0.27, P <0.01). Childhood psychological abuse was positively correlated with mobile phone addiction and anxiety symptoms ( r =0.29, 0.71, P <0.01). Mobile phone addiction and anxiety symptoms were positively correlated ( r =0.30, P <0.01). Childhood psychological abuse could effectively predict depressiove symptoms, mobile phone addiction and anxiety symptoms ( β =0.08, 0.06, 0.66, P <0.01). Mobile phone addiction and anxiety symptoms had a chain mediating effect between childhood psychological abuse and depression symptoms, with a total indirect mediating effect (effect=25.27%, P <0.05), accounting for 72.44% of the total effect.@*Conclusions@#Mobile phone addiction and anxiety symptoms play a chain mediating role between childhood psychological abuse and depressive symptoms. Focusing on childhood psychological abuse, mobile phone addiction and anxiety among college students are beneficial for depression symptoms prevention.

Objective@#To understand the status quo of school bullying among middle school students in Anhui Province and its correlation with family environment and education methods of students related to school bullying, so as to provide corresponding prevention and controlling measures against school bullying.@*Methods@#The investigation has been conducted on the occurrence of school bullying among middle school students ranging from junior grade one to senior grade three in Hefei, Wuhu, Fuyang of Anhui Province, during which up to 1 826 students information has been gathered through Questionnaire Atar Platform using the school bullying scale and self designed questionnaire. SPSS 26.0 statistical software has been applied for data analysis.@*Results@#The incidence of bullying was 41.40%, and among them, 14.46% were reported to bully others, 39.59% of them were of being bullied, and 12.65% of them were reported of bullying others and being bullied at the same time. Multivariate Logistic regression corrected model showed that quiet relationship with mother ( OR=1.76, 95%CI =1.22-2.53) was a risk factor for the bully, quiet relationship with father( OR=1.89, 95%CI=1.47-2.43 ), reorganized family ( OR=2.28, 95%CI =1.22-4.29) were the risk factors for the bullied, quiet/poor relationship between parents ( OR=1.52, 95%CI=1.06-2.17; OR=3.15, 95%CI =1.79-5.57) was a risk factor for the bully-bullied; Punishment and abuse( OR=1.45, 95%CI=1.10-1.90; OR=1.82, 95%CI=1.48-2.23; OR=1.47, 95%CI = 1.10- 1.96) were risk factors for the above three behaviors( P <0.05).@*Conclusion@#The incidence of school bullying is influenced by family environment and rearing style. In daily life, parents should be mindful of maintaining a good family relationship, fostering active communication with child, which can reduce the occurrence of school bullying.
ABSTRACT
Objective:To observe the clinical efficacy of Tongdu Tiaoshen needling combined with cognitive therapy treating post-stroke depression.Method:Sixty patients with post-stroke depression were randomized into observation group and control group,30 cases in each group,using different methods to the two groups of patients based on basic treatment of cerebrovascular disease for 4 weeks.The observation group was intervened by Tongdu Tiaoshen needling combined with cognitive therapy,while the control group was by oral treatment of Paroxetine Hydrochloride Tablets.Cinical effects and side effects were evaluated with Hamilton Depression Scale (HAMD) and Assessment of daily living ability (Barthel index) and National Institute of and Treatment Emergent Side Effect Scale (TESS),and serum levels of 5-HT were measured before and after intervention.Result:The two groups after treatment compared with before treatment,HAMD scores were significantly lower (P＜0.05),Barthel index was increased (P＜0.05),the observation group was significantly better than the western medicine group,with significant differences between the two groups (P＜0.05),The serum 5-HT levels in two groups were significantly higher than those before treatment(P＜0.05),and the increase of 5-HT levels in the two groups was not statistically significant (P＞0.05).The total effective rate was 93.3％ in the treatment group versus 86.7％ in the control group,and the difference was statistically significant (P＜0.05).The adverse reactions in observation group was lower than that in western medicine group,the difference was statistically significant (P＜0.05).Conclusion:Tongdu Tiaoshen needling combined with cognitive therapy intervention for post-stroke depression is an effective approach to improve the depression of patients with PSD,and has good repeatability of clinical operation with low side effects.Its therapeutic mechanism may be related to increase serum 5-HT level.
ABSTRACT
OBJECTIVE:To compare therapeutic efficacy of rosuvastatin vs. atorvastatin for blood lipid,atherosclerosis and vascular endothelial vasodilation in patients with coronary heart disease(CHD). METHODS:A total of 150 CHD inpatients select-ed from cardiovascular medicine department of our hospital during Jan. 2014-Dec. 2015 were divided into rosuvastatin group (72 cases)and atorvastatin group(78 cases)according to lottery method. All patients were adjusted to living habits,given antiplatelet and blood pressure regulating drugs and other basic treatment. At the same time,rosuvastatin group was given Rosuvastatin calcium tablets 10 mg,po,once a night;atorvastatin group was given Atorvastatin calcium tablets 20 mg,po,once a night. Both groups received treatment for 6 months. The levels of blood lipid indexes (TC,TG,HDL-C,LDL-C),IMT,Crouse scores,Gensini scores and the changes of brachial artery diameter(D)were compared between 2 group before and after treatment. The occurrence of ADR was recorded. RESULTS:Before treatment,there was no statistical significance in above indexes between 2 groups(P>0.05). After treatment,the levels of TC,TG,LDL-C,IMT,Crouse scores and Gensini scores in 2 groups were decreased signifi-cantly,while the levels of HDL-C and D values were increased significantly,compared to before treatment;the levels of TC,TG, LDL-C,Crouse score and Gensini score in rosuvastatin group were significantly lower than atorvastatin group,and D value was significantly higher atorvastatin group,with statistical significance(P<0.05). There was no statistical significance in the levels of HDL-C or IMR between 2 groups (P<0.05). During treatment,dizziness occurred in a patient of rosuvastatin group and relieved spontaneously. Four patients in each group had slight elevation of transaminase,and could be reduced to normal after liver protec-tion treatment. CONCLUSIONS:Rosuvastatin shows more significant therapeutic efficacy than that of atorvastatin in reducing blood lipid,improving AS and vascular endothelial vasodilation in CHD patients with good satety.
ABSTRACT
The formation of physique was influenced by many factors and was closely related to the disease, especially by the social and cultural factors. According to the characteristics of physique, physique conditioning was conducive to rehabilitation of the disease. It was also the internal evidence for individualized treatment of rehabilitation. Traditional Chinese medicine (TCM) rehabilitation advocated functional rehabilitation as the main treatment purpose. Attentions were paid to promoteqi circulation. The psychological characteristics of the rehabilitation subject were especially emphasized on, in order to improve the therapeutic effect of rehabilitation. There were many classifications of physical evaluations, which were widely used in a variety of clinical diseases rehabilitation. The pathological physique correction and adjustment cannot be ignored in rehabilitation. Therefore, the application of physical evaluation in the guidance of rehabilitation therapy can enrich the content of TCM rehabilitation evaluation. It further improved TCM physical evaluation system to meet the needs for clinical practice and TCM modernization.
ABSTRACT
Objective To investigate the different distribution and expression of mammalian target of rapamycin complex (mTORC) in the kidney of diabetic nephropathy (DN) mice.Methods Fourteen eight-week-old male C57BL/6 mice were assigned to 2 groups: the control group ( n=7 ) and the streptozotocin ( STZ )-induced DN group ( n=7 ) . Blood and urinary variables including glucose , albumin, creatinine and albumin/creatinine ratio were assessed 2 weeks after STZ injection.Hematoxylin-eosin staining was performed for renal pathological analyses .The distributions of mTOR , phosph-ser2448-mTOR(p-mTOR), mTORC1(Raptor), mTORC2(Rictor) and phosph-ser240/244-S6K1 (p-S6K1) were determined by immunofluorescence.The expression levels of mTOR, p-mTOR, mTORC1(Raptor), mTORC2(Rictor), S6K1 and p-S6K1 were detected by Western blotting .Results Two weeks after STZ injection , the diabetic mice developed albuminuria (P<0.01) and renal hypertrophy (P<0.05).The immunofluorescence positive staining for mTOR , Raptor, and Rictor was distributed in the epithelial cells of proximal tubules , glomerular mesangium and capillary loops as well as the medullary collecting ducts of the control mouse kidney .These positive signals increased in the DN mouse kidney ( P<0.05).However, pS6K1 was not detected in the inner medulla of control mouse and p-mTOR was not found in the glomeruli of both control and DN mice .Conclusion mTORC is widely expessed in the mouse kidney and participates in the development of DN , whereas the 2448 serine phosphorylation of mTOR may be not implicated in the hyperglycemia mediated glomerular injury .
ABSTRACT
In this study, the effects of hyperosmolality on the expression of urea transporter A2 (UTA2) and aquaporin 2 (AQP2) were investigated in transfected immortalized mouse medullary collecting duct (mIMCD3) cell line. AQP2-GFP-pCMV6 and UTA2-GFP-pCMV6 plasmids were stably transfected into mIMCD3 cells respectively. Transfected mIMCD3 and control cells were cultured in different hypertonic media, which were made by NaCl alone, urea alone, or an equiosmolar mixture of NaCl and urea. The mRNA and protein expression of AQP2 was elevated by the stimulation of NaCl alone, urea alone and NaCl plus urea in AQP2-mIMCD3 cells; whereas NaCl alone and NaCl plus urea rather than urea alone increased the mRNA and protein expression of UTA2 in UTA2-mIMCD3 cells, and all the expression presented an osmolality-dependent manner. Moreover, the mRNA and protein expression of UTA2 rather than AQP2 was found to be synergistically up-regulated by a combination of NaCl and urea in mIMCD3 cells. It is concluded that NaCl and urea synergistically induce the expression of UTA2 rather than AQP2 in mIMCD3 cells, and hyperosmolality probably mediates the expression of AQP2 and UTA2 through different mechanisms.
ABSTRACT
In current study, the expressions of protein kinase C (PKC)-α, βⅠ and βⅡ as well as their correlation to the expression of transforming growth factor-βⅠ (TGF-βⅠ) and vascular endothelial growth factor (VEGF) were investigated in glomeruli of normal renal tissues taken from human kidney tumors and kidney tissues from patients with diabetic nephropathy (DN). The accumulation of glomerular extracelluar matrix (ECM) was determined by PAS staining, the expressions of PKC-α,PKC-βⅠ, PKC-βⅡ, TGF-βⅠ and VEGF were measured by semi-quantitative immunohistochemistry.Our results showed that in glomeruli of normal renal tissues, PKC-α and βⅡ had a strong expression whereas the expression of PKC-βⅠ was weak; in glomeruli of DN patients, the expressions of PKC-α,PKC-βⅠ, VEGF and TGF-βⅠ and the accumulation of ECM increased significantly, but the expression of PKC-βⅡ decreased markedly. Meanwhile, the expressions of PKC-α and βⅠ had a positive correlation to the expressions of VEGF and TGF-βⅠ respectively, whereas PKC-βⅡ showed no correlation to VEGF and TGF-βⅠ. It is concluded that the expressions of PKC-α, βⅠ and βⅡ in glomeruli of normal subjects and DN patients are different. PKC-α seems to play a critical role in human DN by up-regulating VEGF expression, whereas PKC-βⅠ is relatively important for the up-regulation of TGF-βⅠ and the accumulation of ECM under diabetic conditions.
ABSTRACT
In current study, the expressions of protein kinase C (PKC)-alpha, betaI and betaII as well as their correlation to the expression of transforming growth factor-betaI (TGF-betaI) and vascular endothelial growth factor (VEGF) were investigated in glomeruli of normal renal tissues taken from human kidney tumors and kidney tissues from patients with diabetic nephropathy (DN). The accumulation of glomerular extracelluar matrix (ECM) was determined by PAS staining, the expressions of PKC-a, PKC-betaI, PKC-betaII, TGF-betaI and VEGF were measured by semi-quantitative immunohistochemistry. Our results showed that in glomeruli of normal renal tissues, PKC-alpha and betaII had a strong expression whereas the expression of PKC-betaI was weak; in glomeruli of DN patients, the expressions of PKC-alpha, PKC-betaI, VEGF and TGF-betaI and the accumulation of ECM increased significantly, but the expression of PKC-betaII decreased markedly. Meanwhile, the expressions of PKC-alpha and betaI had a positive correlation to the expressions of VEGF and TGF-betaI respectively, whereas PKC-betaII showed no correlation to VEGF and TGF-betaI. It is concluded that the expressions of PKC-alpha, betaI and betaII in glomeruli of normal subjects and DN patients are different. PKC-alpha seems to play a critical role in human DN by up-regulating VEGF expression, whereas PKC-betaI is relatively important for the up-regulation of TGF-betaI and the accumulation of ECM under diabetic conditions.
ABSTRACT
Objective To study the cytopathogenic effect of epidemic hemorrhagic fever with renal syndrome virus (HFRSV) on renal tubular cells(RTC). Methods Human fetal renal tubular cells (HFRTC) were cultured in vitro. HFRTC infected or not infected by HFRSV were observed by using trypan-blue stain and transmission electron microscopy(TEM). Viral-mRNA was detected by in situ molecular hybridization. Results (1) HFRSV could directly infected HFRTC: (2)The death rate of HFRTC in the infection group was significantly higher than that in the control grou 1 to 4 weeks after infection; (3) Injuries of cell membrane and cell organs after infection with HFRSV were significantly earlier and more severe as compared to control by means of TEM. Conclusion HFRSV can directly damage renal tubular cells (RTC ), which contributes to the pathogenesis of hemorrhagic fever with renal syndrome (HFRS).
