Chemotherapy based on cisplatin or its combination therapy is a common cancer treatment method. However， the non-specific side effects of cisplatin， poor pharmacokinetic properties of small molecule drugs， and susceptibility to drug resistance greatly limit the clinical application of cisplatin as first-line anti-tumor drug. With the development of nanocarrier technology， liposomes have become an ideal carrier for delivering cisplatin drugs due to their excellent properties of targeting， reducing toxicity， and enhancing efficacy. This paper reviews the status of cisplatin liposome both domestically and internationally which have entered clinical trials， including L-NDDP，SPI-077®， Lipoplatin®，LiPlaCis，SLIT and ILC， etc. Currently， only Lipoplatin® and ILC are showing good potential in cancer therapy. Although cisplatin liposome has made some progress in reducing systemic toxicity and improving treatment efficiency in clinical research， there is still potential for further improvement in tumor targeting and reducing side effects. In the future， more low-toxicity and efficient cisplatin liposomes can be developed through formulation technologies such as co-delivery liposome， stimuli-responsive liposome and targeting liposome.

BackgroundAs a high prevalence disorder， schizophrenia has caused significant burden to family and society due to the impairment of occupational and social function. Currently， the dominant vocational training model in China follows a paternalistic， clinician-led decision-making approach. Although it improves patients' social function to some extent， it undermines their autonomy and treatment adherence. Therefore， it is urgently necessary to explore a new intervention method to enhance treatment compliance and social function in patients. ObjectiveTo explore the impact of shared decision-making oriented vocational training on social function in hospitalized schizophrenia patients， so as to provide references for rehabilitation interventions. MethodsA total of 68 patients diagnosed with schizophrenia according to the International Classification of Diseases， tenth edition （ICD-10） criteria were consecutively enrolled from January to June 2024 at The Third People's Hospital of Wenjiang Distric， Chengdu. Participants were randomly allocated into the research group （n=34） and the control group （n=34） using a random number table method. Both groups received routine rehabilitation training， while the research group received shared decision-making oriented vocational training for 12 weeks， 2 times a week for 2 hours each time. Before and at the 4^th and 12^th week of intervention， two groups were evaluated by General Self-Efficacy Scale （GSES）， Stigma Scale for Mental Illness （SSMI）， Scale of Social function of Psychosis Inpatients （SSFPI） and Inpatient Psychiatric Rehabilitation Outcome Scale （IPROS）. ResultsA total of 63 participants completed the study， with 30 cases in the research group and 33 cases in the control group. Repeated measures ANOVA revealed statistically significant time effects and interaction effects in both groups for GSES， SSMI， SSFPI and IPROS scores （F=20.451， 16.022； 26.193， 12.944； 23.957， 5.023； 11.776， 3.985， P<0.05 or 0.01）， while no significant group effects were observed （F=0.188， 0.742， 1.878， 0.474， P>0.05）. At the 12^th week of intervention， there were statistically significant differences in GSES， SSMI， SSFPI and IPROS scores between the two groups. ConclusionShared decision-making oriented vocational training may help to improve social function in patients with schizophrenia. ［Funded by 2023 Chengdu Medical Research Project （number， 2023468）］

BackgroundThe issue of depression among adolescents is becoming increasingly serious， seriously endangering their healthy development. The issue of sleep disturbances in adolescents with depressive disorder is gradually receiving attention， but there is currently a lack of research on the relationship between sleep quality and suicide risk in this patient population. ObjectiveTo explore the relationship between suicide risk and sleep quality in adolescents with depressive disorders， and analyze the influencing factors of suicide risk， so as to provide references for clinical intervention. MethodsA total of 101 adolescents patients who met the diagnostic criteria for depressive disorder in the International Classification of Diseases， 10th edition （ICD-10） and were hospitalized at Hefei Fourth People's Hospital from June 2020 to February 2023 were selected. The patients were evaluated using the Nurses' Global Assessment of Suicide Risk （NGASR） and Pittsburgh Sleep Quality Index （PSQI）. According to the NGASR score， patients were divided into severe suicide risk group （n=35） and non-severe suicide risk group （n=66）. Pearson correlation analysis was used to examine the correlation between sleep quality and suicide risk in adolescents with depression. Multiple Logistic regression was used to analyze the influencing factors of severe suicide risk in adolescent patients with depression. ResultsStatistically significant differences were found between the two groups in terms of academic pressure， peer relationship and family relationship （t=3.942， 4.378， 6.748， P<0.05）. Moreover， there was a statistically significant difference in PSQI score between two groups （t=7.398， P<0.05）. There was also a statistically significant difference in sleep quality between the two groups （χ²=4.986， P<0.05）. Pearson correlation analysis showed a positive correlation between total PSQI score and NGASR score （r=0.698， P<0.05）. Severe depression （OR=1.628， 95% CI： 1.079~2.457）， high academic pressure （OR=1.118， 95% CI： 1.018~1.228） and poor sleep quality （OR=1.158， 95% CI： 1.033~1.297） were identified as risk factors of severe suicide risk， while good relationships with classmates （OR=0.908， 95% CI： 0.826~0.998） and family （OR=0.904， 95% CI： 0.823~0.993） were protective factors. ConclusionSleep quality in adolescents with depression is negatively correlated with suicide risk and poor sleep quality may be a risk factor for severe suicide risk.

Background Schizophrenic patients have metabolic disorders,impaired language and information processing function.Inflammatory factors may play an important role in the occurrence and development of schizophrenia.Objective To explore the relationship of the inflammatory factor levels with metabolic levels,language fluency and information processing function in patients with schizophrenia,so as to provide references for clinical understanding of the neuropathological mechanisms of schizophrenia.Methods A total of 96 patients with schizophrenia were included in the study group,who were hospitalized in the Fourth People's Hospital of Hefei from January 2021 to December 2022 as well as met the diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders,fifth edition(DSM-5)and Mini-International Neuropsychiatric Interview(MINI)6.0.Meanwhile,population who underwent physical examination at the same hospital were included in the control group(n=42).A high-sensitivity multi factor electrochemiluminescence analyzer was used to detect the levels of inflammatory factors IL-4,IL-5,IL-7,IL-8,IL-10 and IL-13.A fully automated biochemical analyzer was used to detect the levels of metabolic indicators such as fasting blood glucose,triglycerides,high-density lipoprotein,apolipoprotein A,creatinine and urea nitrogen.Verbal fluency and information processing function of all participants were assessed by using Verbal Fluency Test(VFT)and Stroop Color Word Test(SCWT).Results There were statistically significant differences in the levels of IL-4,IL-5,IL-7,IL-8,IL-10,IL-13 and IL-15 between the study group and the control group(P<0.05).There were statistically significant differences in BMI,waist circumference,fasting blood glucose,triglycerides,high-density lipoprotein,urea nitrogen,apolipoprotein A and creatinine levels between the two groups(P<0.05).The differences in the correct number of household appliances,animals,fruits,vegetables,names starting with"water"and"self"in VFT between the two groups were statistically significant(P<0.05).The differences in point reaction time,character reaction time and character color reaction time in SCWT between the two groups were statistically significant(P<0.05).Correlation analysis showed that except for creatinine levels,the levels of IL-4 and IL-5 in patients with schizophrenia were correlated with other indicators(P<0.05).IL-7 levels were correlated with creatinine levels,household appliances,animals,fruits,correct number of names starting with"water"in VFT,point reaction time and word reaction time in SCWT(P<0.05).IL-8 levels were correlated with triglyceride levels,household appliances,animals,fruits,vegetables,correct number of names starting with"water"and"self"in VFT and word reaction time in SCWT(P<0.05).Except for creatinine levels and the correct number of names starting with"self",IL-10 levels were correlated with all other indicators(P<0.05).Except for creatinine and urea nitrogen levels,IL-13 levels were correlated with other indicators(P<0.05).Conclusion The levels of inflammatory factors in patients with schizophrenia may be related to their metabolic levels,language fluency and information processing function.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

ObjectiveTo investigate the expression and role of response gene to complement 32 （RGC32） in liver regeneration after partial hepatectomy （PH）. MethodsA total of 42 male C57BL/6 mice， aged 10 weeks， were randomly divided into control group， postoperative day 1 group （1－d group）， postoperative day 2 group （2－d group）， postoperative day 4 group （4－d group）， postoperative day 6 group （6－d group）， postoperative day 8 group （8－d group）， and postoperative day 10 group （10－d group）， with 6 mice in each group. In the control group， the complete liver of the mice was resected for weighing and photography as the normal control group （sham group）； further， the left and middle lobes of the liver were resected for weighing and photography as the surgical control group （0－day group）； the sham group and the 0－day group shared the same group of mice. After successful modeling by PH， the mice were sacrificed on days 1， 2， 4， 6， 8， and 10 after surgery， and the liver was collected to measure the change in size. HE staining and oil red O staining were used to evaluate liver histomorphological changes； serum alanine aminotransferase （ALT） and aspartate aminotransferase （AST） were measured to evaluate the changes in liver function； immunohistochemical staining was used to measure the expression of proliferating cell nuclear antigen （PCNA） and Ki67 and analyze the change in cell proliferation during liver regeneration； quantitatie real－time PCR and immunohistochemical staining were uused to measure the expression and subcellular distribution of RGC32 during liver regeneration； EdU cell proliferation assay was used to analyze the effect of RGC32 overexpression or knocknout on hepatocyte proliferation in L02 cells. For continuous data， comparison between multiple groups was made by analysis of variance， and further pairwise comparisons were conducted using the LSD－t test. The independent samples t－test was used for comparison of continuous data between two groups. A Pearson correlation analysis was performed. ResultsThe liver gradually enlarged after PH， and the liver/body weight ratio rose to the peak from days 0 to 6， with significant differences between different time points （all P<0.05）， while there was no significant change in liver size from days 6 to 10. The number of liver lipid droplets significantly increased after PH surgery and gradually decreased with liver regeneration， with a significant difference between the portal vein region and the central vein region （all P<0.05）. Compared with the sham group， the 1d group had significant increases in the serum levels of ALT and AST （all P<0.05）， which gradually returned to the levels of the sham group on day 6 and day 2 after surgery， respectively （P>0.05）. Immunohistochemical staining showed that there were rapid increases in the numbers of PCNA－ and Ki67－positive liver parenchymal cells after PH surgery， with the highest numbers of 86±5 and 89±5， respectively， on day 2， which then gradually decreased； however， there were gradual increases in the numbers of PCNA－ and Ki67－positive nonparenchymal cells， with the peak numbers of 34±5 and 25±3， respectively， on day 6， which then gradually decreased. The total expression of RGC32 increased to the highest level on day 2 after PH surgery and then gradually decreased， and the changing trend of RGC32 expression in cytoplasm was consistent with that of total RGC32 expression； however， the expression of RGC32 in nucleus decreased to the lowest level on day 2 after PH surgery and then increased gradually. The correlation analysis showed that the expression of RGC32 in nucleus was negatively correlated with the proliferation of liver parenchymal cells （R²=0.308 3， P=0.016 7）， and the expression of RGC32 in cytoplasm was positively correlated with the proliferation of liver parenchymal cells （R²=0.808 6， P<0.000 1）. Cell experiments showed that compared with the control group， the EdU－positive rate was reduced by 15.6% after RGC32 overexpression （P<0.01） and was increased by 19.2% after RGC32 knockdown （P<0.01）. ConclusionLiver parenchymal cells and nonparenchymal cells show asynchronous proliferation and participate in liver regeneration together. During liver regeneration after hepatectomy， there are differences in the expression of RGC32 between nucleus and cytoplasm， and RGC32 in nucleus may inhibit hepatocyte proliferation.

Objective:To explore the current situation of nursing human caring in hospital wards and analyze its influencing factors, so as to facilitate the development of nursing human caring practice.Methods:From July to November 2022, a total of 107 hospitals were surveyed through stratified convenience sampling method, and 4 072 ward nursing managers were recruited to finish the general information questionnaire and the ward nursing human caring status questionnaire. The general information included the region, class and type of the hospital, etc. The ward nursing human caring status questionnaire included 38 items in 5 dimensions of nursing human caring system and process, humanistic quality and training of nursing staff, humanistic environment and facilities, human caring procedures and measures, and human caring quality evaluation and improvement, with a full score of 190 points. Descriptive statistics were used to analyze the general data, independent samples t-test, ANOVA and correlation analysis were used to analyze the factors influencing the current status of nursing human caring in the ward, while multiple linear regression analysis was used to conduct a multivariate analysis. Results:The score of nursing human caring in hospital wards was 156.91±27.78. Whether the hospital had carried out nursing human caring pilot(demonstration) wards, whether the ward had previously been a hospital nursing human caring pilot(demonstration) nursing unit, the type of ward, and whether nursing managers had participated in human caring training were the influencing factors of the implication of nursing humanistic caring in wards( P<0.05). Conclusions:The practice of nursing human caring in hospital wards is at a good level, but needs to be further strengthened. Nursing managers should take systematically strategies to promote the development of nursing human caring practice.

China is stepping up its standardized management of investigator initiated trials(IIT)carried out by medical and health institutions, spotlighting the establishment and improvement of the quality control system of IIT projects than ever before. The authors retrieved official websites of clinical research related units of medical institutions and research institutes at home and abroad, and by means of literature review analyzed the current quality management of IIT projects at home and abroad. They found such setbacks as lack of quality management standards and norms, imperfect quality control mechanism, poor awareness of quality risk, insufficient quality supervision and poor quality control ability of clinical researchers. Based on the above, the paper made the following recommendations for building an IIT project quality control system in China: developing quality management standards and norms, setting up a systematic quality control mechanism(i.e., exploring a three-level quality control mode composed of the project team/department-hospital-national supervision institution/peer review expert team, and implementing the whole process quality control mechanism), strengthening policy guidance and system construction, and strengthening the standardized training of clinical researchers.

Objective:To reveal the expression and regulation network of microRNA (miRNA) and mRNA in ovarian endometriosis using high-throughput sequencing, and then explore the potential pathogenesis.Methods:From January 2017 to January 2018, twenty patients with ovarian endometriosis in Xiangya Hospital of Central South University were enrolled. Ectopic endometrium and paired eutopic endometrium were collected when surgery was conducted. After total RNA was extracted, miRNA sequencing and mRNA sequencing were performed respectively. Differential miRNA and mRNA expression profiles were analyzed. Predicted mRNA were obtained by Targetscan and miRDB databases, and then intersected with differential mRNA to obtain candidate mRNA. miRNA-mRNA regulatory network was analyzed using Cytoscape software, whereas gene ontology (GO) and pathway function enrichment were performed by DAVID database.Results:Compared with eutopic endometrium, there were 369 miRNAs (197 up-regulated, 172 down-regulated) and 3 765 mRNAs (1 975 up-regulated and 1 790 down-regulated) differentially expressed in ectopic endometrium. Real time quantitative polymerase chain reaction (qRT-PCR) confirmed that the expression of mir-202-5p and mir-514a-5p in ectopic endometrium was higher than that in eutopic endometrium ( P<0.05), while the expression of mir-375-3p, mir-449b-5p in ectopic endometrium was lower than that in eutopic endometrium ( P<0.05). Bioinformatics found that the candidate mRNA related to these four miRNAs are mainly enriched in biological processes of nuclear steroid hormone receptor binding, transmembrane receptor and protein kinase activity, and participate in transforming growth factor β (TGF β) signal pathway, adhesion junction, Wnt signal pathway and Rap1 signal pathway. Conclusions:miRNA and mRNA are differentially expressed in endometriosis, and exact important regulatory network in the development of endometriosis by involving multiple biological processes.
