ABSTRACT

Objective:To study the characteristics and influencing factors of coping styles of clinical ophthalmic interns under psychological stress, so as to provide scientific basis for promoting the mental health development of medical students.Methods:In 2019, 103 students of Sun Yat-sen University who participated in clinical practice of ophthalmology were investigated by cluster sampling with general situation questionnaire and simple coping style questionnaire. The database was established by Epidata, and the data was statistically analyzed by SPSS 25.0 software.Results:The scores of positive coping and negative coping were (1.70±0.10) and (1.30±0.05) respectively, which were all lower than the norm ( P < 0.001). The scores of non first time practice students were 0.087 points higher than those of first time practice students; the scores of eight-year students were 0.124 points higher than those of five-year students; the scores of positive coping increased by 0.015 points for each level of family income increase. Men scored 0.027 points higher than women in negative coping scores; eight-year students scored 0.053 points lower than five-year students in negative coping scores; family income increased by one grade, negative coping scores decreased by 0.017 points; rural registered residence students scored 0.035 points higher than urban registered residence students in negative coping scores; non first practice students scored 0.074 points higher than the first practice students in negative coping scores. Conclusion:Educators should pay close attention to the coping styles of clinical ophthalmic interns, carry out mental health education and guidance of coping methods according to the characteristics of different groups, take effective measures to improve students' stress coping ability and promote the smooth development of clinical practice in ophthalmology.

ABSTRACT

Objective@#Study the response of GMDTC to cadmium ions and metal ions in vivo to determine whether GMDTC are specifically complexed with cadmium ions to provide a reference for the safety and dfficacy of GMDTC.@*Methods@#Complexometric titration, HPLC and HPLC-MS were applied to research the complexation reaction of GMDTC and various metal ions. The molecular ion peak of GMDTC, GMDTC-Cd complex and GMDTC-Pb complex also detected by LC-MS. Additionally, the initial structure was determined by DFT simulation method.@*Results@#Results of complexometric titration and HPLC detection showed that GMDTC characteristic absorption peak area was proportional to the concentration of itself and there was no color change and peak time change when the GMDTC mixed with Ca2+, Fe2+, Mg2+, Zn2+. However, the color changed to black transition when the GMDTC mixed with Cu2+ and the color changed from yellow precipitate to light yellow transparent transition when GMDTC mix with Hg2+. Moreover, the peak area as well as the retention time has changed a lot which indicated that a chemical reaction has already happened. When the GMDTC mixed with Cd2+ and Pb2+, the color has changed from pale yellow to colorless transparent and the peak area of GMDTC has increased a lot. Finally, the GMDTC-Cd complex ratio both of which are 2:1 were calculated based on the results of LC-MS instrument and atomic calculations.@*Conclusion@#The specific cadmium chelating agent GMDTC can not react with the Ca2+, Fe2+, Mg2+, Zn2+, but it can react chemically with Cu2+ and Hg2+, even specific complex with Pb2+ and Cd2+.

ABSTRACT

OBJECTIVE: To establish a New Zealand rabbit model of acute kidney injury induced by cisplatin. METHODS: A total of 24 male New Zealand rabbits were randomly divided into control group,low-,medium-and high-dose cisplatin group according to the body mass. Rabbits were injected with cisplatin at 0. 0,1. 0,2. 0,4. 0 mg/kg body weight by auricular vein. Rabbits in low-dose group was continuously injected for 5 days,medium-dose group was continuously injected for 3 days,and the high-dose group was injected for once per day. Rabbits in the control group did not receive any treatment. Blood was collected from the middle ear artery and 24 h urine was taken before exposure and on day 1,day 3,day 5 and day 7 of injection. The serum creatinine( Scr) and urea nitrogen( BUN) were detected by colorimetric method,and 24 h urine kidney injury molecule 1( KIM-1) was measured by enzyme-linked immunosorbent assay. Plasma platinum,24 h urinary platinum and renal platinum level were detected by inductively coupled plasma mass spectrometry.At the end of the experiment,rabbits were sacrificed and the left kidney was taken for histopathological examination.RESULTS: The body mass of rabbits of the low-,medium-and high-dose groups on day 7 after cisplatin exposure was lower than that of the control group( P < 0. 05),and lower than that of the same group before exposure( P < 0. 05). After 3 days of exposure,the Scr level in each dose group was higher than that of the control group( P < 0. 05),the Scr level on day 3and day 5 in medium-and high-dose groups were higher than that of the low-dose group( P < 0. 05). The BUN levels on day 3 and day 5 in medium-and high-dose group were higher than that of the control group and low-dose group( P <0. 05),the BUN levels on day 7 in three dose groups were higher than that of the control group( P < 0. 05). The levels of plasma platinum and 24 h urinary platinum in the three doses groups of New Zealand rabbits on day 1,day 3,day 5 and day 7 after exposure were higher than that of the control group( P < 0. 05),and were higher than the pre-treatment levels of the same group( P < 0. 05). The level of 24 h urinary KIM-1 in the meclium-dose group of New Zealand rabbits was higher than that of the control group on day 3 of exposure( P < 0. 05). The level of 24 h urinary KIM-1 in the mediumdose group of New Zealand rabbits on the 5th day after exposure was higher than that of the control group( P < 0. 05). The renal platinum levels in the three groups of New Zealand rabbits were higher than that in the control group( P < 0. 05).The pathological changes of rabbit kidney caused by cisplatin are mainly tubular dilatation,protein cast,alkalophilic and interstitial nephritis. CONCLUSION: Cisplatin can induce acute kidney injury in rabbits,and the degree of injury is dosedependent. The dose of 1. 0 mg/kg body weight continuous injection for 5 days is closely related to clinical use of cisplatin,which is recommended for model establishment.

ABSTRACT

Objective To investigate regional activity abnormalities of patients with liver cirrhosis before and after liver transplantation using resting-state fMRI and amplitude of low frequency fluctuations (ALFF)method.Methods Totally 11 patients preparing to accept liver transplantation were adopted into liver cirrhosis group and 11 healthy volunteers in the health examination were adopted into the control group. The liver cirrhosis group was investigated at a week before operation and repeatedly a month after liver trans-plantation.Healthy volunteers were investigated at the same time.MR imaging data were obtained from a Phil-ips Achieva 1.5-T MR imager.The imaging data were mainly preprocessed with a MATLAB toolbox called DPARSF.REST software was used to calculate the ALFF value of each subject.A second-level random-effect two-sample t-test was performed on the individual ALFF.Significant differences were set at the standard of a corrected cluster level of P<0.05,and software Xjview 8.1 was adopted to express the outcome.Results (1)Compared with control group,decreased ALFF were found in bilateral middle occipital gyrus(MOG) (MNI:x=36,y=-72,z=9),bilateral precuneus/cuneus(PCu/Cu)/posterior cingulated(PCC)(MNI:x=15,y=-66,z=24),left inferior parietal lobule(LIPL)(MNI:x=-39,y=-54,z=42),and bilateral para-central lobule/cingulate gyrus(MNI:x=3,y=-36,z=45)of cirrhosis patients,no increased ALFF were found.(2)Compared with cirrhosis patients,no increased or decreased ALFF were found in postoperative group.After relaxing standards of statistics,increased ALFF were found in left inferior parietal lobule(IPL) (MNI:x=-39,y=-51,z=42),cingulate gyrus(MNI:x=3,y=-33,z=42),and right middle frontal gyrus (MNI:x=35,y=57,z=0)of postoperative group,no decreased ALFF were found.(3)Compared with control group,decreased ALFF were found in bilateral precuneus/posterior cingulated(PCC),and left middle occipi-tal gyrus(MOG)of postoperative group,no increased ALFF were found.Conclusions Significant decreased ALFF is found in visual cortex(PCu),DMN((PCu/Cu/PCC),and LIPL of cirrrhosis patients,and those ab-normalities reflect the weakness of local neurons spontaneous low-frequency.Compared with beforeoperative group,ALFF of LIPL,in cingulate gyrus,and right middle frontal gyrus have a tendency of rising.One month after liver transplantation,decreased ALFF is found in BA7 and BA 31,suggesting that the spontaneous low-frequency of local neurons haven't recoverd to normal level.

ABSTRACT

OBJECTIVE: To explore different doses of sodium(s)-2-(dithiocarboxylato((2R,3R,4R,5R,6R)-2,3,4,5,6-pentahydroxyhexyl) amino)-4-(methylthio) butanoate(GMDTC) for removing cadmium. METHODS: Thirty-five male New Zealand rabbits were randomly divided into blank control group,GMDTC high dose control group,model control group,ethylene diamine tetraacetic acid(EDTA) control group and GMDTC low,medium and high dose groups,five rabbits in each group. The blank control group and GMDTC high dose control group were given 0. 90% normal saline solution intravenously; model control group,EDTA control group and GMDTC low,medium and high dose group were given 2 μmol/kg of cadmium chloride(CdCl_2) and 40 μmol/kg of β-mercaptoethanol mixed solution intravenously,5. 0mL/kg body weight(bw),once a day for five days. On the forty-one day of the experiment(the fist day of GMDTC treatment),the control group and the model control group were injected 0. 90% normal saline solution 250 mL via ear vein,the EDTA control group was given EDTA solution at the dose of 93. 5 mg/kg bw with 250 mL 0. 90% normal saline solution,also via ear vein; the GMDTC high dose control group,and the GMDTC low,medium and high dose groups were given 250 mL GMDTC solution at the concentration of 108.0,12.0,36.0 and 108. 0 mg/kg bw with 0. 90% normal saline by intravenous infusion,once a day,6 times a week for four consecutive weeks. The urine β_2-microglobulin(MG),renal cadmium,blood cadmium,and urinary cadmium before and after the treatment were detected. RESULTS: The body weight of New Zealand rabbits increased with the increasing feed time(P < 0. 01). The levels of β_2-MG before treatment increased in model control group,EDTA control group,GMDTC low,medium and high dose groups than that in the blank control group(P < 0. 01). The levels of renal cadmium after treatment in GMDTC medium and high dose groups decreased compared with those in the blank control group and EDTA control group respectively(P < 0. 05). The blood cadmium after treatment in EDTA control group,GMDTC low,medium and high dose groups were decreased compared with those before treatment in the same group respectively(P < 0. 05),meanwhile decreased than the blood cadmium after treatment in the model control group respectively(P < 0. 05). The blood cadmium after treatment had not a statistically significant difference among the EDTA control group,GMDTC medium and high dose groups(P < 0. 05). At all the time points(1,6,8,13,15,20,22 and 28 days after treatment),the urinary cadmium after treatment in EDTA control group and the three GMDTC dose groups increased compared to the model control group at the same time(P < 0. 05). The urinary cadmium after treatment increased with GMDTC dose increased at the other six time points,expect on 20 and 22 days after treatment(P < 0. 05). The blood cadmium removal rates after treatment were 70. 06%,74. 86% and 78. 05% and the renal cadmium removal rates were 14. 27%,27. 95% and 61. 24% in GMDTC low,medium and high dose groups,respectively. CONCLUSION: The intravenous infusion of GMDTC at the dose of 108. 0 mg/kg bw effectively removed cadmium in cadmium poisoning rabbit. This dose had no obvious toxic effect and was equivalent to human dose of 36. 0mg/kg bw which meets the requirement of new drug property.

ABSTRACT

BACKGROUND:Retinoic acid is the most promising inducer for neuroblastoma minimal residual lesion, and it can induce cel differentiationin vivo, accompanied by reducing tumor cel proliferation. OBJECTIVE:To study the effect of nanoparticle labeling on biological characteristics of neuroblastoma stem cels, and the role of 13-cis retinoic acid to induce differentiation of neuroblastoma stem cels. METHODS:Neuroblastoma stem cels were isolated and culturedin vitro using serum-free suspension culture method, labeled with polylysine-modified γ-Fe2O3 nanoparticles and induced in culture medium containing 13-cis retinoic acid. RT-PCR was used to detect the expression of Oct-4 before and after labeling as wel as before and after induction. Immunofluorescence method was used to detect the expression of nestin before and after labeling as wel as before and after induction. RESULTS AND CONCLUSION:Neuroblastoma stem cels were successfuly cultured in the bone marrow samples from 5 of 20 cases. Polylysine-modified γ-Fe2O3 nanoparticle labeling did no influence the viability and proliferation ability of neuroblastoma stem cels, and also had no effect on Oct-4 mRNA and nestin expression. After cultured in the culture medium containing 13-cis retinoic acid, the cel shape changed and the growth rate slowed down. Moreover, the expression of Oct-4 mRNA and nestin was gradualy reduced. These findings indicate that polylysine-modified gamma-Fe2O3 nanoparticles can be used to label neuroblastoma stem cels, and 13-cis retinoic acid can induce the differentiation of neuroblastoma stem cels.

ABSTRACT

Objective To test the efficacy of cognitive behavioral self help therapy for chronic insomnia (CBTI-SH) patients with hypnotic long-term use.Methods A total of 60 adults with chronic insomnia and common comorbidities were recruited.Participants were randomly assigned to either intervention group (IG,n =30) if they had used hypnotics more than 6 months,or control group(CG,n =30) if they had never used hypnotics in the past 6 months.All the patients were given CBTI-SH for 4 weeks.The primary outcome was self-report symptom,based on sleep diaries (including Sleep Latency(SL),Wake after Sleep Onset(WASO),Total Sleep Time(TST),Time In Bed(TIB),Sleep Efficiency(SE) which were evaluated on baseline and at the end of the 2nd,4th week treatment.Continuous variables were evaluated by repeated-measures multivariate analyses of variance (MANOVA).At the conclusion of treatment,each participant was asked how many days per week they enacted each of 6 core elements of the CBT regimen.Linear regression models were examined to determine net predictors of CBTI-SH adherence.Results The MANOVA showed a significant treatment group × time interaction,as well as time main effects for SE,TIB and WASO(P<0.05).The patients in CG made better improvements than those in IG on SE,TIB and WASO((0.19 ±0.08) vs(0.09 ±0.09),(92.48 ± 32.64) vs (78.06 ±60.05),(103.08 ±64.82) vs (64.92 ±56.36),respectively) (P < 0.05).Effect size were 1.14,0.85 and 0.62 respectively.Self-ratings of treatment adherence showed patients in the IG reported less adherence to standard rise time and TIB prescription than those in CG.(P < 0.05).According to the linear regression models,both age and the comorbidity of chronic somatic diseases explained net associations with CBTI-SH adherence (P < 0.05).Conclusion Chronic insomnia patients with hypnotic long-term use show less sleep improvement and less adherence to CBTI-SH compared with those who don' t use these medicines.Both age and the comorbidity of chronic somatic diseases explain net associations with CBTI-SH adherence.

Results (1)The means of sexual life satisfaction,Lacores and four indexes of social support in group A were significantly higher than those in group B(P<0.05),but P's and N's scores in group A lower than those in group B (P<0.05). (2) Stepwise multiple regression ana-lyses showed that only sexual life satisfaction (sβ=0.487) and objective social support (sβ=0. 158) entered the equation in whole sample (r=0.290). Conclusion (1) There axe significant differences of sexual life satisfac-tion, personality characteristics and social support among the women with different marital satisfactions.

ABSTRACT

Objective To explore the relationship between sleep disorder and management strategies in the elderly patients with primary hypertension.Methods The sleep status of 122 elderly patients with primary hypertension was evaluated by Pittsburgh Sleep Quality Index(PSQI) and Coping Style Questionnaire(CSQ).Results The mean score of PSQI was 8.34±3.81,and 63.93% (78/122) of the participants experienced sleep disorder.The most commonly used management strategy wag "problem-solving" (0.74±0.18) and "rationalization" (0.56±0.19).The management strategies were different by gender and age.The lowest score was found in the "ask-for-help" group(t=2.326,P=0.022),which was negatively related with sleep disorders (r=-0.208,P=0.022).Conclusions Intervention of management strategy in elderly patients with primary hypertension may help to improve their sleep quality.

ABSTRACT

Objective To explore the risk factors of antidepressant treatment emergent suicidal ideas or attempted suicide among patients with bipolar depression. Methods Out of 623 patients with bipolar disorder visiting between June 2006 and June 2009,68 who was initially diagnosed as unipolar disorder and treated with antidepressants were retrospectively surveyed. Suicide and activation symptoms during the process of antidepressant treatment were estimated based on the cases record and semi-structural interviews. Unconditional bivariate logistic regression was conducted to analyze the potential risk factors. Results Of 68 patients,7 ( 10. 3% ) experienced antidepressant treatment emergent suicidal ideas and 4 ( 5.9% ) attempted suicide after 2 to 63 ( 17.45 ± 5.90 )days following the treatment. The antidepressant treatment emergent suicidal ideas or attempted suicide were related to the suicidal level before treatment (P= 0. 012, OR = 2. 072 ) and the combined use of benzodiazepine (P =0. 043, OR = 0.236). Clinical subtypes, gender, age, symptoms feature, types of antidepressant and antidepressanttreatment emergent activation symptoms had little impact on the antidepressant treatment emergent suicidal ideas orattempted suicide (P > 0.05 ). Conclusion The antidepressant treatment emergent suicidal ideas or attempted suicide among patients with bipolar depression are positively related to the suicidal level before treatment while negatively associated with the combined use of benzodiazepine.
