Efficacy and prognostic factors analysis of CT-guided 125I seeds implantation for primary hepatocellular carcinoma / 中华核医学与分子影像杂志

Objective:To evaluate the efficacy and prognostic factors of 125I seeds implantation for primary hepatocellular carcinoma. Methods:From December 2011 to January 2021, 102 primary hepatocellular carcinoma patients (86 males, 16 females; median age 61 years) who underwent 125I seeds implantation from 5 hospitals in China were enrolled in this retrospective study. Local progression-free survival (LPFS), overall survival (OS) and the prognostic factors were analyzed. Kaplan-Meier method was used to draw the distribution curve of survival time, and LPFS rate and OS rate were calculated. Log-rank test and Cox regression were used to analyze the influencing factors of survival. Results:The median follow-up time was 38 months until April 2021. The local control rate was 96.1%(98/102). The 1-, 3- and 5-year LPFS rate were 61.3%, 25.5% and 12.7%, and the 1-, 3- and 5-year OS rate were 73.9%, 39.1% and 22.6%, respectively. There were 75 patients with progressive disease, including 42 patients with intrahepatic recurrence and metastasis after seed implantation, and 55 patients died. Multivariate analyses showed that short-term efficacy complete response (CR) (hazard ratio ( HR)=0.34, 95% CI: 0.20-0.58) was protective factor related to LPFS; short-term efficacy CR ( HR=0.25, 95% CI: 0.13-0.47) was the protective factors related to OS; Barcelona clinic liver cancer (BCLC) C stage ( HR=2.33, 95% CI: 1.27-4.27), intrahepatic progression and extrahepatic metastasis ( HR=3.18, 95% CI: 1.28-7.86; HR=3.23, 95% CI: 1.27-8.21) were independent risk factors related to OS. No sever adverse effects were observed. Conclusions:125I seeds implantation is safe and effective for the treatment of primary hepatocellular carcinoma. BCLC stage, short-term efficacy and post-implantation progression are independent factors related to survival time.

125I seed implantation for early stage non-small cell lung cancer—analysis of clinical efficacy and prognosis factors / 中华放射医学与防护杂志

Objective:To analyze the efficacy and safety of radioactive 125I seed implantation in the treatment of unresectable early-stage non-small cell lung cancer (NSCLC), in order to provide data for clinical practice and relevant research. Methods:A retrospective study was conducted on the data of 39 patients with early-stage NSCLC who received CT-guided radioactive 125I seed implantation from Dec 2010 to Dec 2018 in multiple hospitals.The seed implantation process consisted of preoperative planning and design, CT-guided puncture, seed implantation, and postoperative evaluation and dose verification.The efficacy and complications of the treatment were analyzed.The clinical efficacy was evaluated by adopting the Response Evaluation Criteria in Solid Tumors (RECIST) (v1.1) and the adverse reactions were evaluated using the Common Terminology Criteria for Adverse Events (CTCAE v4.0). Results:All the patients were 70 years old on average (51-85). The median lesion diameter was 2.7 cm (1.1-6.0 cm), the median seed activity was 0.7 mCi (0.6-0.8 mCi), while the median follow-up duration was 29 months (3-97 months). Meanwhile, the 1-, 3-, and 5-year overall local control rates were 89.5%, 79%, and 79%, respectively, and the 1-, 3-, and 5-year overall survival rates were 100%, 74.8%, and 49.9%, respectively.Local recurrence and distant metastasis were the main causes of failure, accounting for 17.9% (7 cases) each.The incidence of pneumothorax was 56.4% (22 cases), among which nine cases (23.1%) required invasive closed thoracic drainage.Only 1 case of grade-2 radiation pneumonia (2.6%) was observed, with no other adverse reactions such as dermatoses, esophagitis, or myelitis being discovered.As indicated by univariate analysis, the patients with KPS scores of 80-90, pathological type of adenocarcinoma, T stage of T 1-2, and D90>180 Gy exhibited better local control ( χ2=6.202, P<0.05). Meanwhile, high D90 was also associated with a higher survival rate ( χ2=6.907, P<0.05). Conclusions:Radioactive 125I seed implantation is a safe and effective treatment for unresectable early-stage NSCLC.In cases where external beam radiotherapy is not available, radioactive 125I seed implantation can be considered as one of the treatment options.Pneumothorax is the most common complication of radioactive 125I seed implantation, and adenocarcinoma (pathological type) and higher values of D90 are predictors of better local control.

Objective:To investigate the natural course and psychosocial risk factors of depressive symptoms in college freshmen.Methods:Changes in depressive symptoms among college freshmen were observed for two year periods,self-reporting questionnaires were used to collect data every half yearly.The depressive symptoms were assessed with the Centre for Epidemiological Study-Depression Scale,and psychosocial factors were tested as the potential risk factors,rating by Zung Self-Rating Anxiety Scale,Eysenck Personality Questionnaire-Neuroticism Subscale,Rosenberg Self-Esteem Scale,Frost Multidimensional Perfectionism Scale,Parental Rearing Scale,Adolescents Self-Rating Life Events Checklist,Epworth Sleepiness Scale,daytime sleep time,Godin Leisure-Time Exercise Questionnaire.Generalized estimating equations model was used to analyze the date.Results:Totally 1339 college students were recruited in the survey.It was found the depressive scores significantly increased in the second and third surveys,then decreased in the fourth and fifth surveys.Male (Coef=-1.01,SE =0.42,P =0.017),not interested in the major (Coef=3.89,SE =1.42,P =0.006),neuroticism(Coef =0.79,SE =0.23,P =0.001),self-esteem(Coef =-1.57,SE =0.25,P ＜ 0.001),anxiety(Coef =4.79,SE =0.16,P ＜ 0.001),life events (Coef =0.08,SE =0.01,P ＜ 0.00l),daytime sleepiness (Coef =0.80,SE =4.56,P ＜ 0.001) were significantly correlated with depressive symptoms.Conclusion:The first year of college is a critical time in the prevention depression.Not interested in the major,high neuroticism,low self-esteem,anxiety,life events,daytime sleepiness may be risk factors of depressive symptom in college students.

Cognitive functions in patients with depressive disorder,hyperlipidemia disorder, and comorbid both of the disorders / 中国心理卫生杂志

Objective:To compare the cognitive functions in patients with depressive disorder,hyperlipidemia disorder,and comorbid both of the disorders.Methods:A cross-sectional study was performed in age,gender and education year matched patients with depressive disorder (n =51)(according to the ICD-10),hypedipidemia(n =38) (according to the Chinese adult lipid guideline),comorbid both of the disorders(n =40) and normal controls (n =56) were recruited in this study.All subjects received a battery of neuropsychological tests to access the anxiety and depression symptoms and cognitive function.Results:The scores of MoCA were lower in the patients with comorbid both disorders and patients with depression than patients with hypedipidemia [(24 ± 3),(24 ± 4)vs.(26 ± 3),Ps ＜0.05],and were lower in patients with depression than in normal controls(25 ±3),P ＜0.05.Stroop color test amends numbers were higher in patients with comorbid disorder than in the other three groups (Ps ＜0.05).The scores of immediate and delayed logical memory were higher in patients with hyperlipidemia than in other three groups (Ps ＜0.05).The total number of words in verbal fluency test were lower in patients with comorbid disorders and patients with depression than in patients with hyperlipidemia (Ps ＜0.05).Wisconsin card sorting test category completes were lower in patients with comorbid disorders and patients with depression than in patients with hyperlipidemia and normal controls (Ps ＜ 0.05).The scores of persistent errors were higher in patients with comorbid disorders and patients with depression than in patients with hyperlipidemia and normal controls (Ps ＜0.05).Conclusion:In this study,patients with depressive disorder have impairment of cognitive function,while hyperlipidemia may probably do not impair cognitive function.

Preincubation with low dose of hydrogen peroxide enhances anti-oxidative stress potential of mouse BMSCs / 基础医学与临床

Objective To investigate the effects of preconditioning with low-concentration hydrogen peroxide ( H2O2 ) on oxidative stress-induced bone marrow mesenchymal stem cells ( BMSCs ) apoptosis and its mecha-nism.Methods Mouse bone marrow mesenchymal stem cells ( BMSCs) were isolated and purified by differential centrifugation, and were treated with 0,200,250,300, 500 μmol/L H2O2 after preincubation with 50 μmol/L H2O2 or control medium.Apoptosis of these cells was measured by flow cytometry, and the expression of phos-phorylated PI3K, Akt and mTOR was analyzed by Western blot; BMSCs were also primed with PI3K inhibitor LY294002 for 30 min, then preincubated with 50 μmol/L H2O2 or control medium for 12 h before treatment with 300 μmol/L H2O2.Expression of apoptosis proteins Bcl-2, Bax, caspaase-3, cleaved-caspase-3 and the key pro-teins of the PI3K/Akt/mTOR pathway were detected by Western blot .Results H2O2 induced BMSCs apoptosis in a dose-dependent manner ,and pretreatment of BMSCs with low concentration of H2O2 significantly decreased H2O2-induced apoptosis of the BMSCs .Western blot results revealed that preconditioning with low-concentration H2O2 re-markably reversed the decrease in Bcl-2, total and phosphorylated PI3K, Akt and mTOR levels, and increased in Bax, cleaved-caspase-3 expression after high-dose H2O2 treatment.Such effects were antagonized by PI3K inhibitor LY294002 .Conclusions Preincubation with low-concentration H2O2 may indnce resistance of BMSC to oxidative stress, and such effect may be mediated by inhibition of pro-apoptotic proteins and activation of the PI 3K/Akt/mTOR pathway .

Effects of Fluoxetine and Electroacupuncture on G-protein Level in Platelet Membrane from Patients with Major Depression / 中国心理卫生杂志

Objective: Affective disorder patients can be effectively treated by electro-acupuncture methods without many side effects, but the mechanism of the treatment is not known. The object of this study was to discover whether there is change of guanine-nucleotide-binding protein (G-protein) level in platelets membrane from major depression patients before and after treatment by fluoxetine and electro-acupuncture. Methods:We utilized selective antibodies to quantitate the levels of the G-protein ? subunits in platelets membrane of 78 major depression patients (24 received fluoxetine treatment, 24 received electo-acupuncture treatment and 30 received placebo treatment) and 30 matched comparison subjects.Result:Levels of both G?i and G?q of the patient groups were higher than matched normal comparison subjects before treatment of fluoxetine and electro-acupuncture,the level of G?i and G?q did not change after the treatment of fluoxetine, electro-acupuncture and placebo. The level of G?s wasn't significantly different with matched comparison subjects.Conclusion:The levels of G?i、G?q in platelets membrane from major depression patients are higher than normal, the high levels of G?i and G?q in platelets membrane may be a trait abnormality for major depression patients, not a state abnormality for major depression.
