ObjectiveTo investigate the current status of emergency management for severe mental disorders in Shanghai, and to provide countermeasures and suggestions for the establishment of a sound emergency management system for severe mental disorders and the enhancement of emergency management capability. MethodsA questionnaire survey and qualitative interviews were used to conduct an investigation into the emergency management in 17 district-level mental illness prevention and control institutions in Shanghai, which includes the basic situation of emergency management for severe mental disorders, the construction of emergency response teams and personnel, emergency preparedness drills and training, emergency management plans and rules and regulations, and problems encountered in emergency management. ResultsIn terms of emergency management mechanism and basic situation, resources such as personnel allocation, security funds and green channel were well equipped in each district-level mental illness prevention and control institution in Shanghai. However, the equipment of some hardware facilities was still insufficient to some extent. Therefore, further improvement on the emergency management mechanism for severe mental disorders was needed. With regard to the construction of emergency team and personnel allocation, the majority were those aged between 35‒<45 years old, with a bachelor’s degree, and more than 10 years of working experience. For example, 90.27% staff in district-level mental illness prevention and control institution had a bachelor’s degree or above, which was higher than that among the staff in community-level (73.60%); staff majored in clinical medicine in district-level institution accounted for the proportion at 52.71%, higher than that among the staff in community-level (28.86%); 57.24% staff in district-level institution had an intermediate professional title, higher than that among the staff in community-level (42.28%); and 69.90% staff in district-level institution had more than 10 years of working experience, higher than that among the staff in community-level (43.62%). In the aspect of emergency drills and training, all district-level mental illness prevention and control institutions in Shanghai had a high demand for emergency training, and the weak aspects mainly focused on lack of emergency service protocols, skills of addressing technical challenges, and construction of effectiveness evaluation system. Moreover, the teaching methods were primarily centered on case analysis, simulation drills, interactive discussions, and so forth. Concerning emergency management plans and rules and regulations, all districts in Shanghai had relatively established well-developed systems for emergency response plans, emergency response leadership groups, and emergency response operational task forces for severe mental disorders. About half of the institutions had established other rules and regulations related to emergency management of severe mental disorders in addition to emergency plans. ConclusionShanghai has initially established an emergency management system for severe mental disorders, but it is still fragile in specialized training for emergency management of severe mental disorders, construction of emergency management mechanisms, and the building-up of grassroots emergency teams. Further priorities should include strengthening emergency management training, enhancing the construction of emergency management personnel teams, and gradually establishing a more comprehensive and integrated emergency management mechanism for severe mental disorders.

ObjectiveTo investigate the status of liver function abnormalities in patients with severe mental disorder (SMD) in Shanghai community, to explore the related factors to abnormal liver function in patients with SMD, and to analyze the effects of the types of mental disorders and medication status on liver function abnormalities. MethodsThe patients with SMD in Jinshan District, Minhang District, Hongkou District and Xuhui District of Shanghai were selected as the research subjects. Questionnaire survey, physical examination and laboratory tests were conducted to obtain their demographic characteristics and liver function indicators such as alanine aminotransferase (ALT) and total bilirubin (TBil). The types of mental disorders and medication status of patients in Jinshan District were also investigated. Abnormalities in liver function were determined by abnormalities in either ALT or TBil. Binary logistic regression analysis was used for multivariate analysis of the status of abnormal liver function, and the effects of mental disorder types and medication status on liver function were analyzed, simultaneously. ResultsA total of 7 251 patients with SMD were finally included into this study, and the rate of liver function abnormality was 22.7%, of which 694 cases (9.6%) had ALT abnormality and 1 084 cases (14.9%) had TBil abnormality. Univariate analysis showed that the rate of liver function abnormalities was higher in males than that in females (χ²=45.026, P<0.001), higher in suburbs than that in urban areas (χ²=25.317, P<0.001), higher in those with higher BMI than in those with lower BMI (χ²=63.748, P<0.001), higher in those with elevated blood pressure (BP) than in those without elevated BP (χ²=24.774, P<0.001), higher in those with elevated blood glucose than in those without elevated blood glucose (χ²=43.345, P<0.001), higher in those with abnormal triglyceride (TG) than in those with normal TG (χ²=15.551,P<0.001), and higher in those with abnormal total cholesterol (TC) than in those with normal TC (χ²=10.962, P=0.001). Multivariate analysis showed that the rate of abnormal liver function was higher in males than that in females (OR=1.53, 95%CI: 1.36‒1.73), higher in suburbs than that in urban areas (OR=1.43, 95%CI: 1.21‒1.70), higher in those with overweight than in those with normal BMI (OR=1.16, 95%CI: 1.01‒1.33), higher in those with obesity than in those with those with normal BMI (OR=1.61, 95%CI: 1.36‒1.91), higher in those with elevated blood glucose than in those without elevated blood glucose (OR=1.39, 95%CI: 1.23‒1.58), and higher in those with abnormal TC than in those with normal TC (OR=1.36, 95%CI: 1.13‒1.65).The difference in the rate of ALT abnormalities among the SMD patients in Jinshan District with different medication status was statistically significant (χ²=21.928, P<0.001). Whereas, the differences in the effects of the types of mental disorders and medication status on the status of liver function abnormalities were not statistically significant(P>0.05). ConclusionThe detection rate of liver function abnormalities in community-based SMD patients in Shanghai is high, and male, suburban, and accompanied by elevated BMI, BP, blood glucose, and TC are risk factors for liver function abnormalities in patients with SMD. Primary healthcare providers should pay more attention to the liver function of patients with SMD and initiate targeted and tailored prevention, detection and treatment measures.

Objective This study aimed to investigate the temporal and spatial changes in the expression of perios-tin during periodontal inflammation in mice.Methods A periodontitis model was constructed using silk thread ligation.Mice were randomly divided into five groups in-cluding control group,4-day ligation group,7-day liga-tion group,14-day ligation group,and self-healing group(thread removal for 14 days after 14-day ligation).Mi-cro-CT and histological staining were performed to char-acterize the dynamic changes in the mouse periodontal tissue in each group.RNAscope and immunohistochemical staining were used to analyze the pattern of changes in peri-ostin at various stages of periodontitis.The cell experiment was divided into three groups:control group,lipopolysac-charide(LPS)stimulation group(treated with LPS for 12 h),and LPS stimulation removal group(treated with LPS for 3 h followed by incubation with medium for 9 h).Quantitative real-time polymerase chain reaction(qRT-PCR)was used to detect the expression of periostin,transforming growth factor-β1(TGF-β1),and matrix metalloproteinase 2(MMP2).Results Significant alveolar bone resorption was observed 7 days after ligation.With increasing duration of ligation,the damage to the mouse periodontal tissue was aggravated,which manifested as increased osteoclasts,widen-ing of the periodontal membrane space,and decreased alveolar bone height.Some degree of periodontal tissue repair was observed in the self-healing group.Periostin expression decreased at 4 and 7 days compared with the control group and increased at 14 days compared with 4 and 7 days.A significant recovery was found in the self-healing group.The qRT-PCR results showed that the expression of periostin and TGF-β1 in the LPS stimulation group decreased compared with that in the control group but significantly recovered in the LPS removal group.Conclusion Periostin expression in the PDL of mice showed a downward and upward trend with inflammation progression.The significant recovery of periostin expression after removing inflammatory stimuli may be related to TGF-β1,which is crucial to maintain the in-tegrity of the PDL.

The medication adherence was mainly taking medication on time and in the right amount, with 2 437 cases accounting for 90.80%. Conclusion The main characteristics of schizophrenic patients using long-acting antipsychotic medications are young, unmarried, and unemployed adults, with incomplete self-awareness, continuous medication and medication given by others.

Venous thromboembolism(VTE)includes deep venous thrombosis(DVT)and pulmonary embolism(PE).Patients in intensive care unit(ICU)are often at a high risk of VTE due to combining many risk factors.Prevention strategies of VTE in critically ill patients are crucial,including identification of risk factors,the risk as-sessment of thrombosis and bleeding,mechanical prophylaxis and drug prophylaxis,effect monitoring,and quality control.Since the risk of VTE in ICU patients is high,the risk of bleeding should not be ignored.It is a challenge for ICU physicians to comprehensively evaluate the risk of thrombosis and bleeding in critically ill patients and im-plement effective preventive and monitoring measures in time.This article reviews the relevant research progress on prevention strategies of VTE in critically ill patients in order to provide clinical evidence for the prophylaxis of VTE in critically ill patients.

Objective:To evaluate the clinical efficacy and safety of intense pulsed light combined with fruit acid in the treatment of erythema and pigmentation after facial acne.Methods:From January 2019 to December 2022, 108 patients were selected from Dermatology Hospital of Guangxi Zhuang Autonomous Region, including 30 males and 78 females, aged 20-44 (28.2±5.1) years. The patients were divided into three groups: intense pulsed light group (40 cases), fruit acid group (38 cases) and intense pulsed light combined with fruit acid group (30 cases). The clinical efficacy of the three groups was compared. The facial biological characteristics data of patients were collected with VISIA skin analyzer and the changes compared before and after treatment in each group.Results:The total effective rates of the intense pulsed light group, the fruit acid group and the combination group were 57.5% (23/40 cases), 50.0% (19/38 cases), and 80.0% (24/30 cases), respectively. Comparison of total effective rates among three groups, there were statistically significant differences (χ 2=6.70, P=0.04). Comparison of effective rates among different groups showed that there was no difference between the intense pulsed light group and the fruit acid group (χ 2=0.44, P=0.51); there were significant difference between the intense pulse light group and the combination group (χ 2=3.93, 6.49; P<0.05), and between the fruit acid group and the combination group (χ 2=6.49, P=0.01). After treatment, the VISIA scores of erythema, spots, pores, and purple in three groups of patients significantly decreased compared to before treatment ( P<0.05). The VISIA scores of each observation value showed a decreasing trend with the increase of treatment frequency ( P<0.01). During the treatment, no obvious adverse reactions were observed. Conclusions:Intense pulsed light combined with fruit acid in the treatment of facial erythema postacnes and postinflammatory hyperpigmentation can improve the efficacy and less adverse reactions.

The incidence and mortality of venous thromboembolism (VTE) are high in critically ill patients, and there is still a risk of VTE and bleeding after the use of fixed-dose low molecular weight heparin (LMWH) for prophylaxis. The level of anti-factor Ⅹa is not up to standard after LMWH prophylaxis in patients with surgery or trauma. The condition of critically ill patients is complicated, and the proportion of patients with low antithrombin Ⅲ is high, which can affect the prophylactic efficacy of LMWH and contribute to VTE occurrence. There is currently no consensus on whether adjusting LMWH dose according to anti-factor Ⅹa levels can reduce VTE occurrence in critically ill patients. High-quality multicenter randomized controlled studies are needed in the future to establish new approaches for precise prevention of VTE in critically ill patients.

Objective:To explore the employment experiences of coordinators of In-Hospital Organ Procurement Organization (OPO).Methods:Based on purpose sampling, 12 full-time In-Hospital OPO coordinators in Chongqing City were recruited from July to December 2020. A semi-structured and in-depth interview was performed and the data was analyzed by Colaizzi.Results:4 first-level themes were extracted, including professional identity process, negative emotional experience, improvement of professional practice competence and job expectancy. 12 second-level themes were identified including career expectations and identity confusion, professional values, shortage of respect and ratification, huge workloads, great psychological pressure, influence of the bereaved families, enhancement of the ability to communicate, improvement of problem-solving ability, improvement of team-work ability, optimization of scenario simulation, a perfection of the assessment system, a clear career path.Conclusions:In-Hospital OPO coordinators are lack of professional awareness in an initial stage. While feeling a sense of professional value, they also experience some negative emotions. Furthermore, their competences are improved in practice and they, meanwhile, express a strong desire for career development. It is suggested that the administrators could explore establishment of academic education, enhancement of psychological and social support, creation of pretty working environments and improvement of training, assessment and promotion systems to facilitate the career development of coordinators.

ObjectiveTo explore the relapse status based on the positive and negative syndrome scale （PANSS Scale） and related factors of schizophrenics in Shanghai communities， and to analyze the association between socio demographic characteristics， lifestyles， clinical characteristics and relapse. MethodsA dynamic cohort prospective study design was used in this study. From March 2018 to February 2019， a total of 189 schizophrenics in Xuhui， Hongkou， Changning， Jiading， Songjiang and Baoshan districts were enrolled successively. Baseline questionnaires were conducted through face-to-face interviews at baseline， which contained social demographic information， lifestyle information and clinical information. A follow-up was conducted every 2 weeks for a measurement of PANSS Scale for a total of 6 months. Relapse was assessed by a PANSS score increase of ≥25% from baseline （or an increase of 10 points or more if the baseline score was ≤40 points）. Univariate and multivariate Cox regression models were used to analyze the associations between relapse status （assessed by PANSS Scale） and socio demographic characteristics， lifestyles， and clinical characteristics， respectively. ResultsA total of 165 community schizophrenics completed baseline and follow-up surveys， with a loss to follow-up rate of about 12.7%. After exclusion of sociodemographic and clinical information deficits， 132 patients were included in the analysis totally， with an average age of 48.18±12.67 years， among whom 41.67% were male. Totally 33 patients relapsed during the 6-month follow-up period， with a relapse rate of 25.0%. After adjusting for gender， family history， age， employment， education， marital status， smoking， drinking， exercise frequency， medication compliance， insight， social function， violence history， stress recent events， adverse drug reactions and baseline scores of PANSS Scale， risk factors of relapse included the following four factors： age below 40 years （HR=4.47， 95%CI： 1.15-17.40）， primary school or below （HR=7.11， 95%CI： 1.54-32.83）， unemployed （HR=8.34， 95%CI： 1.78-38.98）， and adverse drug reactions （HR=5.02， 95%CI： 1.75-14.37）. ConclusionWe should pay attention to the risk factors such as age， education， employment and adverse drug reactions， in order to identify high-risk patients and to conduct timely interventions during the relapse management of schizophrenics in Shanghai community.
