ObjectiveTo investigate the value of the serum levels of Clusterin and sphingosine 1-phosphate （S1P） in assessing the prognosis of sepsis patients with acute liver injury. MethodsA total of 127 sepsis patients with acute liver injury who were admitted to Lianyungang Hospital， Xuzhou Medical University， from March 2019 to May 2022 were enrolled， and according to their prognosis after 28 days of treatment， they were divided into death group with 35 patients and survival group with 92 patients. The independent-samples t test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between groups. A pearson correlation analysis was used to investigate the correlation. The prognostic value of serum Clusterin and S1P was analyzed by receiver operating characteristic curve. ResultsThere were significant differences between the two groups in the degree of liver injury， Acute Physiology and Chronic Health Evaluation Ⅱ （APACHEⅡ） score， Sequential Organ Failure Assessment （SOFA） score， the presence or absence of acute kidney injury， prothrombin time （PT）， international normalized ratio （INR）， Child-Pugh class， and C-reactive protein （all P<0.05）. The death group had significantly lower serum levels of Clusterin and S1P than the survival group （t=11.094 and 10.390， both P<0.05）. The patients with severe liver injury had significantly lower serum levels of Clusterin and S1P than those with mild or moderate liver injury （t=9.825 and 11.418， both P<0.05）. The multivariate regression analysis showed that the degree of liver injury （odds ratio ［OR］=1.260， 95% confidence interval ［CI］： 1.081 — 1.468， P<0.05）， APACHEII score （OR=1.031， 95%CI： 1.019 — 1.044， P<0.05）， SOFA score （OR=1.066， 95%CI： 1.039 — 1.094， P<0.05）， Clusterin （OR=0.899， 95%CI： 0.859 — 0.940， P<0.05）， and S1P （OR=0.824， 95%CI： 0.749 — 0.908， P<0.05） were independent risk factors for the prognosis of patients with sepsis. The ROC curve analysis showed that serum Clusterin and S1P used alone or in combination had an area under the ROC curve of 0.864， 0.861， and 0.949， respectively. Serum Clusterin and S1P were significantly negatively correlated with alanine aminotransferase， total bilirubin， PT， and INR in sepsis patients with acute liver injury （all P<0.05）. ConclusionThe sepsis patients with acute liver injury who died had significant reductions in serum Clusterin and S1P compared with those who survived， and the levels of Clusterin and S1P are closely associated with the degree of liver injury. The combination of Clusterin and S1P has a good value in predicting the prognosis of sepsis patients with acute liver injury and is expected to become a potential marker for predicting the prognosis of sepsis patients with acute liver injury.

Association between health literacy and depressive emotion among occupational groups in Shanghai / 环境与职业医学

Background At present, insufficient support for enterprise health environment and career development may lead to severe depressive emotion among occupational groups. Objective To investigate current state of depressive emotion and the relationship between health literacy and depressive emotion among occupational groups in Shanghai, and to provide evidence for formulating health management measures to alleviate depressive emotion among the occupational population. Methods This cross-sectional survey, using two-stage stratified sampling, was from December 2022 to February 2023, and selected 2548 active workers from 151 enterprises in Shanghai. A total of 2489 valid questionnaires were returned, with a recovery rate of 97.68%. Health literacy, internality health locus of control, and depressive emotion were evaluated by the Health Literacy Questionnaire, the Multidimensional Health Locus of Control Scale-Internality Health Locus of Control, and the Patient Health Questionnaire Depression Scale-9 item (PHQ-9), respectively. R 4.2.2 software was used for statistical analysis, binary logistic regression model was used to analyze the association between health literacy, internality health locus of control, and the risk of depressive emotion, and multiple linear model was used to analyze the correlation between health literacy, internality health locus of control, and PHQ-9 related indicators (total score, affective score, and somatic score). Results A total of 2489 workers aged 18 years and above in Shanghai were included in the analysis, 868 of them reported depressive emotion, and the positive rate of depressive emotion was 34.9%. The total score, affective score, and somatic score of PHQ-9 in M(P25, P75) were 3.00 (0.00, 6.00), 1.00 (0.00, 4.00), and 1.00 (0.00, 3.00), respectively. The results of binary multiple logistic regression analysis showed that after adjusting for selected confounders, no health literacy (OR=1.32, 95%CI: 1.10, 1.60; P=0.004) and low level of internality health locus of control (OR=1.66, 95%CI: 1.35, 2.05; P < 0.001) were associated with an increased risk of reporting depressive emotion. The results of multiple linear model showed that the lack of health literacy and low internality health locus of control were positively correlated with the total score, affective score, and somatic score of PHQ-9. Conclusion Depressive emotion among the working population in Shanghai is prominent, and more than 1/3 of them report depressive emotion. Lower health literacy and internality health locus of control are related to an increased risk of depressive emotion in the study population. Improving occupational health literacy and enhancing internality health locus of control are expected to prevent depressive emotion in occupational groups.

Research progress on the mechanism of valproic acid against glioma / 中国药房

Gliomas are commonly central nervous system tumors. The conventional treatment is surgical resection combined with chemoradiotherapy， but glioma patients often have a poor prognosis. Therefore， there is an urgent need to identify new potential targets in gliomas and develop more effective treatments. Valproic acid has the properties of histone deacetylase inhibitor， which has been proven to have inhibitory effects on various tumors. It is confirmed that valproic acid could promote apoptosis and cell arrest of glioma cells， inhibit cell invasion and glioma stem cells， increase the sensitivity of glioma cells to radiotherapy and chemotherapy by regulating ERK/Akt signaling pathway， Akt/mTOR signaling pathway， and regulating expression levels of RECK， MGMT， Nrf2， PON2， Smad4， GSK3β and other proteins. In addition， valproic acid can also enhance the effectiveness of anticancer drugs by inhibiting the growth of glioma stem cells and inducing their differentiation. In conclusion， valproic acid can inhibit glioma through multiple targeted actions， and may become a new targeted drug for the treatment of glioma.

@#Objective To observe the effects of dual-task motor training on motor and balance function for stroke patients. Methods From January, 2016 to June, 2017, 30 patients with stroke were assigned randomly into control group (n = 15) and treatment group (n = 15). Both groups accepted routine physical therapy, the control group accepted anti-gravity treadmill training, while the treatment group accepted dual-task training with anti-gravity treadmill, for four weeks. They were measured with balance training and evaluation system, and assessed with Fugl-Meyer Assessment-lower extremity (FMA-L), Berg Balance Scale (BBS) and modified Barthel Index (MBI), before and after treatment. Results The range of swaying on X axial (Rx) and Y axial (Ry), as well as rectangle area (RecArea) decreased after treatment in the treatment group (t > 4.719, P < 0.001), while RecArea decreased in the control group (t = 5.069, P < 0.001). Ry and RecArea were less in the treatment group than in the control group (t > 2.288, P < 0.05). The scores of FMA-L, BBS and MBI improved after treatment in both groups (t > 7.316, P < 0.001), and improved more in the treatment group than in the control group (t > 2.322, P < 0.05). Conclusion The dual-task training via anti-gravity treadmill may improve motor and balance function in stroke patients, and promote the activities of daily living.

Experience Analysis on National Traditional Chinese Medicine MasterBan XiuwenTreatment of FemaleYin-Wei / 世界科学技术-中医药现代化

National traditional Chinese medicine (TCM) master professor Ban Xiuwen had rich experiences on treatment of gynecological diseases with unique insights on diagnosis and treatment for disorders of menstruation, leukorrhea, pregnancy and delivery. FemaleYin-Wei, which was a gynecological disorder, was recorded in the book ofHuang-Di Nei-Jing. However, due to different reasons, TCM study on femaleYin-Wei was far less than the study on male impotence. ProfessorBan Xiuwen had specific considerations for this disease on the book of Treatment of Miscellaneous Gynecological Diseases. In his understanding, femaleYin-Wei was due to four aspects, which were the innate deficiency, yang deficiency and coldness of the uterus; seven emotion damage, liver-qi soothing disorder; spleen-stomach deficiency,qi-blood deficiency; and phlegm-dampness stasis,qi stagnation. Through the analysis and study on case records of femaleYin-Wei treatment by national TCM master professorBan Xiuwen, this article briefly elaborated professorBan Xiuwen’s understandings on femaleYin-Wei treatment from etiology, pathogenesis, treatment according to syndrome differentiation, and clinical experiences. Two femaleYin-Wei cases treated by professorBan Xiuwen were given as examples in order to analyze the etiology, pathogenesis, treatment according to syndrome differentiation and treatment experiences in details. The therapeutic effects of both cases were obvious, which were also important study documents.
