The ethical review of clinical research involving mental disorders in the ethical governance of scientific and technological has obvious particularities， especially in the field of artificial intelligence and brain-computer interfaces which are reflected in the impact on mental autonomy， the impaired informed consent ability of participants with severe mental disorders in research， and other aspects. In addition， the stigma of illness， the use of placebo， and psychological assessment methods in clinical research have also drawn attention to the ethical review of psychiatry. In 2020， the Beijing Municipal Health Commission issued the Guidelines for Ethical Review of Clinical Research Involving Mental Disorders （Guidelines）. Shen Yucun’s Psychiatry， compiled in 2023， revised the application of the Guidelines in the context of ethical governance. An analysis was conducted on the purpose and significance of its issuance and revision， its scope of application， the principal responsibility of ethical review in medical and health institutions， and the key content of ethical review in psychiatry， to improve the quality of ethical review in clinical research involving mental disorders and promote the standardized development of clinical research in psychiatry.

Drug therapy is a common method to cure diseases and relieve symptoms.The value of patient-reported outcome(PRO)in evaluating the effect of drug therapy has been increasingly paid attention.The PRO scale is a standardized questionnaire,which can scientifically evaluate the experiences and subjective effects of drug use from a patient-centered perspective,and help patients and clinicians make more reasonable medication decisions.By reviewing and sorting out relevant global literature,this paper found that the content of the PRO scales relevant to drug therapy focused on five fields:"medication satisfaction""medication adherence""drug treatment burden""medication-related quality of life"and"adverse drug reactions".This paper described the basic information,measurement characteristics and application of common scales in recent years respectively,and summarized and analyzed the problems and enlightenment of scale development,aiming to provide theoretical reference for the selection,application and development of PRO scales.

Objective To explore the expression of serum Hepcidin,long non-coding RNA myocardial infarction-associated transcript(LncRNA MIAT)and creatinine(CRE)in patients with bipolar disorder(BPD)and their relationship with the severity of the disease.Method In this study,150 patients with BPD who were admitted to Baoji Central Hospital from March 2021 to March 2023 were selected as the study subjects and were included in the BPD group.Another 150 healthy subjects were selected as the control group.Hamilton Depression Scale(HAMD)was used to evaluate depression.Young mania ratings scale(YMRS)was used to evaluate the degree of mania.All subjects were tested for serum Hepcidin,LncRNA MIAT and CRE levels.The levels of serum Hepcidin,LncRNA MIAT and CRE were compared between control group and BPD group.The levels of serum Hepcidin,LncRNA MIAT and CRE in BPD groups with different depression/mania degrees were compared.Receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of serum Hepcidin,LncRNA MIAT and CRE in BPD.The relationship between serum Hepcidin,LncRNA MIAT and CRE and the severity of BPD was analyzed.Results The levels of serum Hepcidin(46.17±9.17 ng/L),LncRNA MIAT(11.92±2.65)and CRE(74.02±11.89 μ mol/L)in BPD group were higher than those in control group(22.16±5.23 ng/L,4.11±0.95,57.16±8.61 μ mol/L),with significant differences(t=-27.856,-43.079,-14.066,all P＜0.05).The levels of serum Hepcidin,LncRNA MIAT and CRE increased with the increase of depression/mania in BPD patients(F=22.036,25.463,17.499;19.552,15.791,18.335,all P＜0.05).The combined detection of serum Hepcidin,LncRNA MIAT and CRE(95％CI:0.866～0.949)for BPD diagnosis had an area under the ROC curve of 0.914,with high specificity and sensitivity,which was significantly higher than that of serum Hepcidin alone(95％CI:0.693～0.816),LncRNAMIAT(95％CI:0.696～0.819)alone and CRE(95％CI:0.587～0.701)detection alone(AUC=0.759,0.762,0.614,all P＜0.05).Serum Hepcidin,LncRNA MIAT and CRE were positively correlated with depression severity in BPD patients(r=0.784,0.771,0.826,all P＜0.05).Serum Hepcidin,LncRNA MIAT and CRE were positively correlated with mania severity in BPD patients(r=0.806,0.793,0.831,all P＜0.05).Conclusion The levels of serum Hepcidin,LncRNA MIAT and CRE in BPD patients were higher than those in the normal population,and they were positively correlated with the severity of the disease.Combined detection may have a high diagnostic value.

Objective:To observe the development process of the neuronal synapse in cerebral cortex and basal ganglionic eminence(GE)regions of the mice,and to clarify the differences in the development of excitatory and inhibitory synapses in different brain regions in vivo and in vitro.Methods:The female C57BL/6 mice were euthanized by cervical dislocation from the 13.5th day to the 15.5th day during the pregnancy,and the embryos were collected under the sterile conditions.The cortex and GE regions of brain tissue of the embryonic mice were gradually isolated under microscope.The primary neurons from the embryonic mice were cultured in vitro,and the cell samples were collected on the 3rd,7th,14th,and 21th days,respectively,and regarded as culture 3 d,7 d,14 d,and 21 d groups.The expression levels of postsynaptic density 95(PSD95)and Gephyrin mRNA in the primary neurons from the cortex and GE regions of the mice in various groups were detected by real-time fluorescence quantitative PCR(RT-qPCR)method.Immunofluorescence method was used to detect the expression levels of vesicular glutamate transporter 1(vGLUT1),PSD95,vesicular GABA transporter(vGAT),and Gephyrin proteins in the neurons from the cortex and GE regions of the mice in various groups.Immunofluorescence method was also used to detect the expression levels of vGLUT1 and vGAT proteins in the neurons from the cortical and GE regions in brain tissue of the embryonic mice.Results:Compared with culture 3 d group,the expression levels of PSD95 and Gephyrin mRNA in cortex and GE regions of the mice in culture 14 d and 21 d groups were significantly increased(P<0.01).Compared with cortex area,the expression level of Gephyrin mRNA in the neurons from GE region of the mice in culture 14 d group was significantly decreased(P<0.01).The microscope observation results showed that the excitatory and inhibitory synapses in the neurons from cortex and GE regions of the mice in culture 14 d group showed preliminary development,with positive expression of relevant proteins;among them,the excitatory synaptic proteins showed more distinct positive expression in the cortex neurons,and the presynaptic vGLUT1 and postsynaptic PSD95 molecules exhibited co-localization in the cell bodies and protrusions of the cortical neurons;the inhibitory presynaptic vGAT protein and postsynaptic Gephyrin protein in the neurons from GE region also exhibited co-localization in the cell bodies and protrusions,and there were more distinct expressions of the presynaptic molecule proteins than postsynaptic molecule proteins.Compared with cortex region,the levels of vGLUT1 and PSD95 proteins in the neurons from GE region of the mice in culture 14 d group were significantly decreased(P<0.01),while the levels of vGAT and gephyrin proteins were significantly increased(P<0.01).In culture 21 d group,the positive expressions of synaptic protein in the neurons from cortex and GE regions were increased,and the excitatory and inhibitory synapses further matured and enhanced.In the neurons from cortex and GE regions,rich patterns of corresponding pre-and postsynaptic expression were formed in the cell bodies and protrusions,and synapse structures showed gradual,positive development,with more apparent expression of presynaptic molecules compared wih postsynaptic proteins.Compared with cortex region,the levels of vGLUT1 and PSD95 proteins in the neurons from GE region of the mice in culture 21 d group were significantly decreased(P<0.01),and the levels of vGAT and Gephyrin proteins were significantly increased(P<0.01).Compared with cortex region,the expression level of vGLUT1 protein in the neurons from GE region in brain tissue of the embryonic mice was significantly decreased(P<0.01),while the expression level of vGAT protein was significantly increased(P<0.05).Conclusion:There are distinct differences in synaptic development between the neurons from cortex and GE regions,the excitatory synapses develope earlier in the cortical region and the inhibitory synapses develope earlier in the GE region.The region-specific development of synapses suggests that different types of neural diseases with different cell types might originate from different developmental processes.

Arsenic is a widely occurring metalloid element in the natural environment and is one of the primary carcinogens identified by the World Health Organization (WHO), but the specific carcinogenic mechanism is currently unclear. In recent years, through toxicological studies on arsenic, it has been found that exposure to arsenic can affect cellular metabolism in the body, which may be closely related to the carcinogenic mechanism of arsenic. Therefore, the authors review the research progress on arsenic exposure-induced effects on glucose metabolism, lipid metabolism, and amino acid metabolism, with a view to providing a theoretical basis for the study of the mechanism of arsenic carcinogenesis.

Pharmacy services in grassroots medical institutions provide professional pharmacy services for patients. This service not only expanded the scope of primary care delivery, but also meets the residents′need for appropriate medication. At present, the majority of grassroots medical institutions in China provide outpatient pharmacy services by means of pharmacy service alliance, and foreign grassroots medical institutions mainly provide pharmaceutical outpatient services with drug treatment management as the core for patients by granting pharmacists partial prescription rights.In recent years, pharmaceutical outpatient services in grassroots medical institutions had achieved good results in improving patient clinical outcomes, enhancing medication rationality, and enhancing patient compliance. However, there were many unresolved issues, including low public awareness, shortage of pharmaceutical talents, and imperfect guarantee systems. The author suggestted that efforts should be made to increase the publicity of pharmaceutical outpatient services, improve the training mechanism for pharmacists, strengthen cooperation between pharmacists and clinical physicians, include pharmacists in the contracted service team of family doctors, and improve various guarantee systems, in order to provide reference for promoting the sustainable development of pharmaceutical outpatient services in grassroots medical institutions in China.

Objective To observe and analyze the difference of serum immunoglobulin IgA, IgG, IgM, β2-microglobulin and transferrin in pre-eclampsia (PE) and pregnancies complicated with chronic kidney disease.Methods Totally 46(40.0%)pregnancies with PE(PE group),36(31.3%)pregnancies with chronic kidney disease(chronic kidney disease group)and 33(28.7%)normal pregnancies with normal blood pressure and proteinuria without any complication(control group)delivered in Renji Hospital were recruicted in this study from February 2017 to July 2017.Serum IgA,IgG,IgM,β2-microglobulin and transferrin levels were detected. Correlation tests were conducted between these indicators and blood pressure, 24 hours proteinuria value and delivery weeks. Results (1) Comparison of general situation of pregnancies in the 3 groups:there were no significant difference in the age and child bearing history between the 3 groups(all P>0.05),while there was a significant difference in the blood pressure and deliver week(all P<0.01).There was no significant difference in 24 hours proteinuria values between PE group and chronic kidney disease group (Z=-0.187, P=0.852). (2) Comparison of serum immunoglobulin, β2-microglobulin and transferrin levels in pregnant women with three groups: serum IgA level in chronic kidney disease group was significantly higher than those in PE and control groups[(2.4±0.9)vs(1.8±0.9)vs(1.6±0.6)g/L;F=9.959,P<0.01].The serum IgG and IgM values had no significant difference between the 3 groups(all P>0.05).Serum β2-microglobulin in chronic kidney disease group was significantly higher than those in PE and control groups[(4.0±2.6)vs(2.7±0.7)vs(2.0±0.5)mg/L;F=15.892,P<0.01].Serum transferrin in chronic kidney disease group was significantly lower than those in PE and control groups[(3.0±0.8)vs(3.7±1.1)vs(3.6±0.6) g/L; F=6.284, P<0.01]. (3) The correlation between serum immunoglobulin, β2-microglobulin, transferrin and blood pressure, proteinuria value and delivery weeks in PE group: the blood pressure level was not correlated with serum IgA,β2-microglobulin and transferrin values in PE group(all P>0.05).So,24 hours proteinuria value was positively correlated with β2-microglobulin (r=0.557, P<0.01), which was negatively correlated with transferrin (r=-0.442, P<0.01) and was not correlated with IgA(r=0.089, P=0.556). There was a negative correlation between delivery weeks and β2-microglobulin(r=-0.328,P=0.026),and positive correlation with transferrin (r=0.315, P=0.035) and no correlation with IgA (r=-0.169, P=0.260). (4) The correlation between serum immunoglobulin, β2-microglobulin, transferrin and blood pressure, proteinuria value and delivery weeks in chronic kidney disease group:the blood pressure level was positively correlated with β2-microglobulin(systolic pressure: r=0.598,P<0.01;diastolic pressure:r=0.557,P<0.01),which was not correlated with IgA and transferrin in chronic kidney disease group (all P>0.05). So,24 hours proteinuria value was positively correlated with β2-microglobulin and IgA(r=0.568,r=0.330,both P<0.05), and not correlated with transferrin (r=0.255, P=0.133). Delivery weeks had a negative correlation with β2-microglobulin(r=-0.574,P<0.01),while it had a positive correlation with transferrin(r=0.369,P=0.027). No correlation was found between delivery weeks and IgA values (r=-0.257, P=0.131). Conclusion The serum levels of IgA,β2-microglobulin and transferrin in PE and pregnancies with chronic kidney disease are significantly different,which may provide clinical value for the diagnosis of PE and pregnancies with chronic kidney disease in future.
