Objective:To investigate the effect of search for meaning on depression and the moderating role of perspective change in college students. Methods:The participants were 1 16 college students. The hypotheses were tested by analyzing data collected at 3 time points. Search for meaning and the presence of meaning in life were measured with the Meaning in Life Questionnaire,the dimension of perspective change in Meaning-Focused Coping Questionnaire was used to assess the ability to change perspective,and depression was assessed with the Center for Epidemiological Studies Depression Scale (CES-D). Results:The scores of perspective change was positively corre-lated with scores of meaning in life (r=0. 29 ,P<0. 0 1 ),and negatively correlated with CES-D scores (r=-0. 34,P<0. 001). The scores of perspective change moderated the relationship between scores of search for mean-ing and scores of presence of meaning in life (β=0. 22,P<0. 01 ),and this interaction effected CES-D scores through the mediation of scores of presence of meaning in life. That is,for the individuals with lower perspectivechange score (blow one standard),the score of search for meaning was negatively associated with the presence of meaning in life,with in turn increased CES-D scores,95%CI:0. 07 -033;among the individuals with higher per-spective change scores (above one standard),there was no mediation effect. Conclusion:The results suggest that perspective change could moderate the relationship between search for meaning and meaning in life,which in turn buffers depression. The findings imply the potential positive role of perspective change in the process of searching for meaning in life among university students.

AbstractObjective: To explore the effect and mechanism of curcumin on human T-cell acute lymphoblastic leukemia (T-ALL) cell apoptosis induced by Mcl-1 small molecule inhibitors UMI-77.
METHODS:
T-ALL cell line Molt-4 was cultured, and the cells were treated with different concentrations of curcumin and Mcl-1 small molecule inhibitor UMI-77 for 24 h. The MTT method was used to detect the cell survival rate after different treatment; According to the results of curcumin and UMI-77, the experimental settings were divided into control group, curcumin group (20 μmol/L curcumin treated cells), UMI-77 group (15 μmol/L Mcl-1 small molecule inhibitor UMI-77 treated cells) and curcumin+ UMI-77 group (20 μmol/L curcumin and 15 μmol/L Mcl-1 small molecule inhibitor UMI-77 treated cells), MTT method was used to detect cell proliferation inhibition rate, Annexin V-FITC/PI double staining method and TUNEL staining were used to detect cell apoptosis, DCFH-DA probe was used to detect cell reactive oxygen species, JC-1 fluorescent probe was used to detect mitochondrial membrane potential, Western blot was used to detect the expression levels of apoptosis-related proteins and Notch1 signaling pathway-related proteins.
RESULTS:
After the treatment of Molt-4 cells with different concentrations of curcumin and Mcl-1 small molecule inhibitor UMI-77, the cell survival rate was decreased (P<0.05); Compared with the control group, the cell proliferation inhibition rate of the curcumin group and the UMI-77 group were increased, the apoptosis rate of cell was increased, the level of ROS was increased, the protein expression of Bax, Caspase-3 and Caspase-9 in the cells were all increased, and the protein expression of Bcl-2 was reduced (P<0.05); Compared with the curcumin group or UMI-77 group, the cell proliferation inhibition rate and apoptosis rate of the curcumin+UMI-77 group were further increased, and the level of ROS was increased. At the same time, the protein expression of Bax, Caspase-3 and Caspase-9 in the cells were all increased, the protein expression of Bcl-2 was reduced (P<0.05); In addition, the mitochondrial membrane potential of the cells after curcumin treatment was decreased, and the proteins expression of Notch1 and HES1 were reduced (P<0.05).
CONCLUSION
Curcumin can enhance the apoptosis of T-ALL cells induced by Mcl-1 small molecule inhibitor UMI-77 by reducing the mitochondrial membrane potential, the mechanism may be related to the inhibition of Notch1 signaling pathway.

There has been an ongoing search for clinically acceptable methods for the accurate, efficient and simple diagnosis and prognosis of hepatocellular carcinoma (HCC). Optical spectroscopy is a technique with potential clinical applications to diagnose cancer diseases. The purpose of this study was to obtain the optical properties of HCC tissues and non-tumorous hepatic tissues and identify the difference between them. A total of 55 tissue samples (HCC tissue, n=38; non-tumorous hepatic tissue, n=17) were surgically resected from patients with HCC. The optical parameters were measured in 10-nm steps using single-integrating-sphere system in the wavelength range of 400 to 1800 nm. It was found that the optical properties and their differences varied with the wavelength for the HCC tissue and the non-tumorous hepatic tissue in the entire wavelength range of research. The absorption coefficient of the HCC tissue (1.48±0.99, 1.46±0.88, 0.86±0.61, 2.15±0.53, 0.54±0.10, 0.79±0.15 mm(-1)) was significantly lower than that of the non-tumorous hepatic tissue (2.79±1.73, 3.13±1.47, 3.06±2.79, 2.57±0.55, 0.62±0.10, 0.93±0.16 mm(-1)) at wavelengths of 400, 410, 450, 1450, 1660 and 1800 nm, respectively (P<0.05). The reduced scattering coefficient of HCC tissue (5.28±1.70, 4.91±1.54, 1.26±0.35 mm(-1)) and non-tumorous hepatic tissue (8.14±3.70, 9.27±3.08, 2.55±0.57 mm(-1)) was significantly different at 460, 500 and 1800 nm respectively (P<0.05). These results show different pathologic liver tissues have different optical properties. It provides a better understanding of the relationship between optical parameters and physiological characteristics in human liver tissues. And it would be very useful for developing a non-invasive, real-time, simple and efficient way for medical management of HCC in the future.

OBJECTIVE: To investigate the characteristics and regularity of hepatotoxicity induced by quinolones, and to provide reference for clinical use of drug safely. METHODS: Using “quinolone” “floxacin” “hepatotoxicity” “hepatic injury”as retrieval words, relevant literatures about hepatotoxicity induced by quinolones were retrieved from domestic and foreign databases as CNKI, Wanfang, VIP, PubMed (during database establishment to 31th, Dec. 2017). Those literatures were summarized and analyzed. RESULTS: A total of 59 valid literatures were collected, including 61 cases of hepatotoxicity induced by quinolones, 8 types of drugs as ciprofloxacin, moxifloxacin, ofloxacin, lomefloxacin, norfloxacin, levofloxacin, gatifloxacin and enoxacin. Ciprofloxacin, levofloxacin, moxifloxacin and ofloxacin were the most common drugs that caused hepatotoxicity, involving 19, 13, 11, 7 cases, respectively; accumulative constitute ratio was 81.97%. The ratio of male to female was 1.54 ∶ 1, and hepatotoxicity always happened at the age of 61 to 80 (30 cases, 49.18%). Primary diseases of 46 cases were single disease (75.41%), and mainly were infection of respiratory system and urogenital system. There were 15 cases of combined disease (24.59%). Thirty-one cases used quinolones alone, most of which was ciprofloxacin. There were 30 cases of drug combination. Thirty-four cases were given drug intravenously and mainly were domestic cases. The hepatotoxicity first occurred within 10 minutes after administration and at the latest 8 weeks after administration. Forty-nine patients suffered from hepatotoxicity within 10 days after medication, accounting for 80.33%. Besides general fatigue, nausea and vomiting, clinical symptoms also included abnormal elevation of alanine aminotransferase, aspartate aminotransferase and total bilirubin,etc. Fifty-four patients were improved after withdrawal or symptomatic treatment, while 7 patients died. The results of causality evaluation of drug-induced hepatic injury showed that there were 4 probably association cases, 45 likely association cases and 12 possible association cases. CONCLUSIONS: The hepatotoxicity caused by quinolones is related to drug variety, patient’s age, primary disease, drug combination and route of administration, and mostly occurs within 10 days after administration. Great importance should be attached to patient’s liver function indexes, strengthen medication monitoring, and carefully combined use of drugs.

Objective To observe Shenci capsule's effect on immunologic function and hematological tox-icity of patients with advanced non-small cell lung cancer.Methods 60 cases of patients with advanced non-small cell lung cancer were chosen and divided into the therapy group and the control group randomly with 30 cases in each group respectively. While patients in the control group were administered simple GP chemotherapy regime, patients in the therapy group were administered Shenci capsule treatment orally in addition to the therapy in the control group.Comparisons were made of the variations in the subgroup of T lymphocyte(including the absolute val-ue of CD3+cell,the absolute value of CD4+cell,the absolute value of CD8+cell and CD4+/CD8+ratio)of hematology before and after chemotherapy between the two groups of patients. Results No significant discrepancy was found in the comparison of the absolute value of CD3+cell,the absolute value of CD4+cell,the absolute value of CD8+cell and CD4+/CD8+ratio before the chemotherapy between the two groups(P > 0.05)and the absolute value of CD3+cell,and the absolute value of CD4+cell of both groups decreased significantly after the chemotherapy(P<0.05), especially in the control group(P < 0.05). The hematological toxicity of the therapy group was lower than that in the control group(P < 0.05)after the chemotherapy. Conclusion Shenci capsule was capable of enhancing the body immunity in advanced non-small cell lung cancer and alleviating hematological toxicity.

Objective To analyze the effect of night-shift work, anxiety and their interaction on work-related musculoskeletal disorders (WMSDs) among electronics manufacturing employees. Methods A total of 2 676 employees from 58 electronic manufacturing enterprises in the Pearl River Delta region of Guangdong Province were selected as the research subjects using the judgment sampling method. The Basic Situation Survey Scale, Generalized Anxiety Disorder 7-item Scale and Questionnaire of Musculoskeletal Disorders were used to assess night-shift work, anxiety and the prevalence of WMSDs in employees. The multivariate logistic regression model was used to analyze the effects of night-shift work, anxiety and their combined effects on the risk of WMSDs. Results The proportion of night-shift work was 30.3%, and the detection rates of anxiety and WMSDs were 26.8% and 41.3%, respectively. The results of multivariate logistic regression analysis showed that night-shift work and anxiety were independent risk factors of WMSDs in the research subjects, after excluding the influence of confounding factors such as age, marital status, enterprise size and length of service [odds ratio (OR) and 95% confidence interval (CI) were 1.307 (1.092-1.564) and 3.282 (2.739-3.934), respectively, both P<0.01]. Compared with those without night-shift work or anxiety, the risk of WMSDs was higher in individuals with only night-shift work, only anxiety, or both night-shift work and anxiety [OR and 95%CI were 1.347 (1.091-1.663), 3.395 (2.727-4.227) and 4.117 (3.072-5.519), respectively, all P<0.01]. Conclusion Both night-shift work and anxiety can increase the risk of WMSDs among electronic manufacturing employees, and these two factors exhibit a synergistic effect in increasing the risk of WMSDs.

ObjectiveTo analyze the current occupational health literacy (OHL) level and its influencing factors among drivers in transportation industry. Methods A total of 880 drivers of taxi companies, passenger transport companies, freight companies and online booking companies were selected as the research subjects using the judgment sampling method. The Occupational Health Literacy Questionnaire of National Key Populations was used to conduct a survey on their OHL levels via online questionnaires, and the influencing factors of OHL were analyzed. Results The OHL level of the research subjects was 54.32% (478/880). The OHL levels in the dimensions of occupational health legal knowledge, basic knowledge of occupational health protection, basic skills of occupational health protection, healthy working style and behavior were 55.34%, 79.55%, 58.30% and 46.25%, respectively. The results of the multivariate logistic regression analysis showed that the OHL levels of drivers in passenger transport and freight companies were higher than that in taxi companies (all P<0.01). The OHL levels of drivers in private enterprises, foreign-funded enterprises, and other enterprises were lower than those in state-owned enterprises (all P<0.05). The OHL levels of drivers in large enterprises were lower than that of drivers in micro-enterprises (P<0.05). The OHL levels of drivers worked >5-10 years and >10 years were lower than that of drivers working 1-5 years (all P<0.05). Conclusion There is a considerable room for improvement in the OHL levels of drivers in the transportation industry. The category, economic type, and scale of the employing unit and driving work year of the current position are the main influencing factors of OHL levels.
