Schizophrenia is a prevalent mental-behavioral disorder characterized by perceptual disturbances,affective dysregulation,and behavioral abnormalities.In traditional Chinese medicine,it is classified under"manic depressive psychosis"according to its symptomatology.The concepts of"spirit,soul,and inferior spirit"originate from Lingshu·Benshen.Drawing on the concept of"spirit governs the soul and inferior spirit"from Lei Jing,this study explored schizophrenia pathogenesis and treatment from the perspective of the three-level regulation of spirit,soul,and inferior spirit.The core pathogenesis involves failure of spirit to govern as the root cause,disruption of soul homing as the pathodynamic process,and the loss of inferior spirit's somatic functional expression as the manifestation.The pathological locations are the heart,liver,and lungs.Therapeutic strategies are developed according to the pathological transmission pattern"spirit derangement,soul floating,inferior spirit dissipation,"forming a treatment system that emphasizes"calming the heart and tranquillization,restoring its control to solidify the root;suppressing the liver soul and regulating the central mechanism to pacify excess to stop mania;purifying the lungs and calming the inferior spirit to restore its clarity and regulate sensory perception and restore cognition."The treatment emphasizes the synergistic use of"calming the spirit,stabilizing the soul,and soothing the inferior spirit,"and combines acupuncture and repetitive transcranial magnetic stimulation and other treatments to treat both the manifestation and root cause of schizophrenia.Exploring the syndrome differentiation and treatment of schizophrenia from the perspective of spirit,soul,and inferior spirit,aiming to provide a theoretical basis for the treatment of schizophrenia with traditional Chinese medicine.

Objective:To compare the efficacy and safety of cold-endoscopic mucosal resection (C-EMR) and hot-endoscopic mucosal resection (H-EMR) for the treatment of colorectal polyps sized 10-20mm.Methods:Patients who underwent colonoscopy at the Gastrointestinal Endoscopy Center of the Eighth Affiliated Hospital, Sun Yat-sen University from January 2022 to January 2023 were selected as the research subjects. Patients meeting the inclusion criteria with at least one 10-20 mm, Paris type Ⅰs, type Ⅱa polyp were selected. They were divided into C-EMR group (no high-frequency current treatment) and H-EMR group (high-frequency electrical polyp removal) based on the random number table method. The main outcome measures were the complete resection rate of polyps, the incidence of postoperative complications (bleeding, perforation and infection), and the recurrence rate of polyps in the two groups. Secondary outcomes were the procedure time and cost-effectiveness.Results:A total of 209 eligible polyps were found in 209 patients, 105 in the C-EMR group (105 patients) and 104 in the H-EMR group (104 patients). There was no significant difference in the complete removal rate of polyps [91.4% (96/105) VS 95.2% (99/104), χ2=1.184, P=0.276], the recurrence rate of polyps [2.9% (3/105) VS 1.9% (2/104), χ2=0.195, P=0.683] or the incidence of complications [5.7% (6/105) VS 1.9% (2/104), χ2=2.040, P=0.280] between the C-EMR group and the H-EMR group. Compared with H-EMR group, the operation time of C-EMR group was shorter (5.26±2.41 min VS 9.34±5.63 min, t=-8.478, P<0.001), and the number of titanium clips used was fewer (2.55±0.94 VS 3.94±1.14, t=-9.623, P<0.001), and the differences between the two groups were statistically significant. The cost of polypectomy was lower in the C-EMR group than that in the H-EMR group (2 720±452 yuan VS 3 031±293 yuan), but the difference was not stastistically significant（ t=-5.896， P=0.651）. Conclusion:C-EMR demonstrates non-inferior efficacy and safety in treating 10-20 mm colorectal polyps compared with H-EMR. Widespread adoption of C-EMR may lead to reduced healthcare costs and expenditures.

Objective To investigate the proportions of myeloid-derived suppressor cells(MDSCs)and their subsets,including poly-morphonuclear MDSCs(PMN-MDSCs),early-stage MDSCs(e-MDSCs),monocytic MDSCs(M-MDSCs),and lectin-like oxidized low-density lipoprotein receptor-1(LOX-1)positive PMN-MDSCs,in the peripheral blood of ovarian cancer(OC)patients and ana-lyze their correlations with clinicopathological parameters of the patients.Methods The proportions of MDSCs and their subsets in the peripheral blood of 38 OC patients(OC group)and 46 healthy individuals(healthy control group)were detected by flow cytometry.The levels of serum IL-10 and TGF-β were detected using ELISA.The OC group was further divided into LOX-1 high and low expres-sion subgroups based on the median proportion of LOX-1+PMN-MDSCs in MDSCs.Results The proportions of MDSCs,PMN-MDSCs,and LOX-1+PMN-MDSCs in the peripheral blood mononuclear cells(PBMCs)of the OC group were significantly higher than those in the healthy control group(U=492,P＜0.001;t=8.741,P＜0.000 1;U=223,P＜0.000 1).The proportions of M-MDSCs and e-MDSCs in the OC group were significantly lower than those in the healthy control group(t=4.366,P＜0.000 1;t=6.927,P＜0.000 1).The proportion of LOX-1+PMN-MDSCs in the lymph node metastasis group of OC patients was significantly higher than that in the non-metastasis group(t=2.249,P＜0.05).The levels of serum IL-10 and TGF-β in the OC group were significantly higher than those in the healthy control group(P＜0.05).In addition,the level of serum TGF-β in the LOX-1 high expression group was significantly higher than that in the LOX-1 low expression group(t=2.302,P＜0.05).Conclusion The proportion of LOX-1+PMN-MDSCs in the peripheral blood of OC patients is significantly increased and closely related to lymph node metastasis.

Objective:To analyze the relationship between 24-hour urinary calcium (24 h UCa) level and the risk of end-stage kidney disease (ESKD), cardiovascular disease (CVD), and all-cause mortality.Methods:In the Chinese Cohort Study of Chronic Kidney Disease, we examined 3 375 patients aged 18-74 years with CKD stages 1-4. Kaplan-Meier survival and Cox proportional hazard regression models were used to test a time-to-event association between levels of 24 h UCa and incidence of ESKD, CVD, and all-cause mortality.Results:During a follow-up of 4.17 (3.37, 5.20) years, 179, 145, 104 and 38 ESKD events occurred in <0.60, 0.60-, 1.20-, ≥2.32 mmol 24 h UCa groups. Higher levels of 24 h UCa (1.20-,≥2.32 mmol) were independently associated with a lower incidence of ESKD events in patients with CKD, with HR (95% CI) of 0.71 (0.54-0.93) and 0.43 (0.29-0.64), respectively. No significant associations with CVD and all-cause mortality endpoints were detected. Conclusion:Among patients with CKD, levels of 24 h UCa displayed an association with the risk of ESKD among patients with CKD stages 1-4.

Objective To analyze the characteristics of adverse drug reactions （ADR） reported in Sixth People’s Hospital South Campus, Shanghai Jiaotong University from 2021 to 2023, to provide reference for promoting rational clinical drug use. Methods ADR data reported in our hospital were collected retrospectively, including patients’ basic information, drugs causing adverse reactions, types of adverse reactions and outcomes. Descriptive analysis methods were used to summarize and analyze the data. Results A total of 979 cases of ADR were reported in our hospital from 2021 to 2023. The highest proportion of patients with ADR occurred in the age range of 31 to 50, and more male patients （63.5%）. The top five drugs involved with adverse reactions were antibiotics （48.8%）, Chinese medicine injections（19.2%）, vitamins（7.5%）, Chinese traditional medicine（7.2%）, equine tetanus immunoglobulin（6.3%）. Among antibiotics, cefuroxime, ceftazidime and cefotiam were the majority. The organs/systems involved in all ADR were mainly skin and accessories damage （55.4%）. The clinical manifestations were rash, itching, and maculopapular rash. Conclusion From 2021 to 2023, the most common drugs causing adverse drug reactions in our hospital were mainly antibacterial drugs, and the rational clinical use of antibacterial drugs still needs to be concerned.

BACKGROUND:There are many problems to completely transform clinical diseases into animal models,but the ideal animal model is the premise of the mechanism research of cervical spondylosis,and it is very important to select the appropriate animal model of cervical spondylosis.OBJECTIVE:To analyze the species,sex,age,type of cervical spondylosis model and its internal molecular mechanism of animal models of cervical spondylosis in detail so as to explore how to select suitable animal models for experimental research of cervical spondylosis.METHODS:PubMed,Medline,Embase,Web of Science,WanFang,VIP,and CNKI databases were searched with Chinese and English search terms"cervical spondylosis,cervical spondylotic myelopathy,cervical spondylotic radiculopathy,cervical spondylosis of vertebral artery type,neck type cervical spondylosis,unbalanced dynamic and static forces,joint injury,neck pain,animal model."According to the inclusion and exclusion criteria,the literature was screened,and finally 61 articles were included for review and analysis.RESULTS AND CONCLUSION:Rats are the most commonly used animals,and males seem to be more popular.It is recommended to use young adult animals.According to the characteristics of molding,cervical spondylosis models were divided into cervical spondylotic myelopath,cervical spondylotic radiculopathy,neck type cervical spondylosis,and other type cervical spondylosis.The advantages and disadvantages of various modeling methods were evaluated.Based on the studies of existing animal models,the molecular mechanism of cervical spondylosis was summarized.Therapeutic signals mediate nuclear factor-κB,phosphatidylinositol-3 kinase/protein kinase B,mitogen-activated protein kinase,and other pathways to regulate the biological processes of inflammation,apoptosis and autophagy of spinal cord,nerve root,intervertebral disc,muscle and other tissues,and ultimately delay the progression of cervical spondylosis.The quality of some studies is poor,and the clinical compatibility is not high.In the future,it is necessary to further standardize the animal model of cervical spondylosis,formulate relevant guidelines,improve the credibility of the research results,and lay a solid foundation for further human clinical trials.

OBJECTIVE: To explore the epidemiological characteristics of knee osteoarthritis (KOA) among the elderly in the community, and its correlation with bone mass loss. METHODS: A cross-sectional study was conducted on elderly community population over 50 year old from 12 community health service centers in Zhejiang province. Their gender, age, body mass index (BMI), T value and KOA diagnosis were collected using face to face questionnaire survey. Univariate regression was used to analyze the influence of age, gender, BMI and bone loss on KOA. Logistic multivariate regression model was used to analyze the independent effect of bone mass loss on KOA. RESULTS: Among 4 173 subjects in this study, 1 710 of them were had a KOA. The prevalence rate was 40.9%. The mean age, the proportion of females and the mean BMI in KOA patients were (65.5±3.8) years old, 67.7%(1 158/1 710) and(24.59±1.28) kg·m^-2, respectively, which were significantly higher than (58.5±3.2) years old, 51.3%(1 263/2 463), and (23.48±1.25) kg·m^-2 in non-KOA subjects (P<0.001). In the population aged from 60 to 69 years old, the influence of osteopenia and osteoporosis on the prevalence of KOA was[OR=1.21, 95%CI(1.00, 1.46), P=0.053 2], [OR=1.42, 95%CI(1.14, 1.78), P=0.002 2]. The influence of male and female osteoporosis on the prevalence of KOA was [OR=1.52, 95%CI(1.16, 1.99), P=0.002 7] and [OR=1.87, 95%CI(1.51, 2.32), P<0.000 1], respectively. In the population of 24 kg·m^-2≤BMI<28 kg·m^-2, the influence of osteopenia and osteoporosis on the prevalence of KOA was [OR=1.47, 95%CI(1.21, 1.80), P=0.000 1], [OR=2.69, 95%CI(2.11, 3.42), P<0.000 1], respectively. After controlling the confounding factors of age, gender and BMI, compared with people with normal bone mass, the effect of osteopenia on the prevalence of KOA was [OR=1.34, 95%CI(1.08, 1.67), P=0.009 2], and the effect of osteoporosis on the prevalence of KOA was [OR=1.38, 95%CI(1.06, 1.79), P=0.017 9]. CONCLUSION Elderly overweight women are more likely to develop KOA. Bone mass loss is an independent risk factor for KOA, which will significantly increase the prevalence of KOA in people overweight or aged 60 to 69 years old.
