Critical care medicine-related treatment is an interdisciplinary and multi-professional process,often leading to secondary or concomitant mental disorders in clinical practice.Currently,there is no consensus on the pharmacological treatment of related mental illnesses in China.The Chinese Society of Psychosomatic Medicine collaborated with the Critical Care Medicine expert group to form a consensus writing expert group.After a systematic review of relevant literature,summarizing published domestic and foreign literature,and extensive discussions,the consensus was developed.The consensus elaborates on the principles and processes of the standardized use of psychotropic drugs in critical care medicine,as well as the clinical indications,precautions,and specific drug selection of various psychiatric medications,providing feasible suggestions and guidance for the clinical application of psychiatric medications in the intensive care unit.

Objective Establishment and evaluation of a mouse model of aldosterone-induced multi-organ damage.Methods Twenty mice were randomly divided into four groups,with five mice in each group:a blank control group(0 μg/(kg·d)),a low-dose aldosterone group(150 μg/(kg·d))),a medium-dose aldosterone group(300 μg/(kg d)),and a high-dose aldosterone group(450 pug/(kg·d)).Aldosterone-containing osmotic minipumps were surgically implanted under the skin,and aldosterone was infused for 4 weeks to establish the aldosterone-induced damage model.The body weight and blood pressure of the mice were recorded weekly.After the 4 week modeling period,the mice were euthanized,and their tissues were collected for observation and analysis of blood pressure and histological morphology of various organs.Results(1)After 4 weeks of aldosterone infusion,the serum aldosterone levels were significantly increased in the medium-dose and high-dose aldosterone groups,but not in the low-dose aldosterone group.(2)After the implantation of osmotic minipumps,the systolic blood pressure was significantly increased in the low-dose,medium-dose,and high-dose aldosterone groups during the second and third weeks,but decreased in all these groups during the fourth week.(3)The kidney and heart in the low-dose,medium-dose,and high-dose aldosterone groups showed varying degrees of damage,interstitial edema,collagen deposition,and fibrotic lesions.The liver in the low-dose aldosterone group showed a small amount of collagen deposition,while the medium-dose and high-dose aldosterone groups showed varying degrees of hepatocyte damage,collagen deposition,and fibrotic lesions.Conclusions Aldosterone can induce multi-organ damage in mice.Under this modeling method,organ damage is mainly manifested as edema,collagen deposition,and fibrotic lesions.

Objective:To evaluate the relationship between intracerebroventricular glial cell line-derived neurotrophic factor (GDNF)-induced improvement in long-term postoperative cognitive function and expression of PKMζ and Kalirin in the hippocampus of neonatal rats.Methods:Sixty 7-day old Sprague-Dawley rats, male or female, were divided into 4 groups ( n=15 each) using a random number table method: control group (group C), GDNF group (group G), surgery group (group S) and surgery plus GDNF group (group S+ G). Group C did not receive anesthesia, surgery or drug treatment. Group G received intracerebroventricular injection of 0.3 μg recombinant rat GDNF. Group S and group S+ G underwent right carotid artery exposure surgery under 3% sevoflurane anesthesia, and in addition group S+ G received intracerebroventricular injection of GDNF. The Barnes maze test and the fear conditioning test were performed starting from postnatal day 33. The animals were then sacrificed under sevoflurane anesthesia after behavioral testing, the brains were obtained and divided into 2 halves sagittally along the midline. The left half of the brain was used for Golgi staining to observe dendritic morphology and measure dendritic spine density. The hippocampal protein was extracted from the right half of the brain to detect the expression of PKMζ and Kalirin by Western blot. Results:Compared with group C, the time to identify the target box in the Barnes maze test was significantly prolonged, the context-related freezing time in the fear conditioning test was shortened, the total dendritic length, the number of branches, the number of intersections in sholl analysis and spinal density in the hippocampus were reduced, and the expression of PKMζ and Kalirin was down-regulated in group S ( P<0.05), and no significant change was found in the aforementioned parameters in group G ( P>0.05). Compared with group S, the time to identify the target box in the Barnes maze test was significantly shortened, the context-related freezing time in the fear conditioning test was prolonged, the total dendritic length, the number of branches, the number of intersections in sholl analysis and spinal density in the hippocampus were increased, and the expression of PKMζ and Kalirin was up-regulated in group S+ G ( P<0.05). Conclusions:The mechanism by which intracerebroventricular GDNF improves long-term postoperative cognitive function may be related to up-regulating the expression of PKMζ and Kalirin and promoting the development of dendrites and dendritic spines in the hippocampus of neonatal rats.

Objective To investigate the clinical characteristics and prognosis of pneumococcal meningitis(PM),and drug sensitivity of Streptococcus pneumoniae(SP)isolates in Chinese children.Methods A retrospective analysis was conducted on clinical information,laboratory data,and microbiological data of 160 hospitalized children under 15 years old with PM from January 2019 to December 2020 in 33 tertiary hospitals across the country.Results Among the 160 children with PM,there were 103 males and 57 females.The age ranged from 15 days to 15 years,with 109 cases(68.1% )aged 3 months to under 3 years.SP strains were isolated from 95 cases(59.4% )in cerebrospinal fluid cultures and from 57 cases(35.6% )in blood cultures.The positive rates of SP detection by cerebrospinal fluid metagenomic next-generation sequencing and cerebrospinal fluid SP antigen testing were 40% (35/87)and 27% (21/78),respectively.Fifty-five cases(34.4% )had one or more risk factors for purulent meningitis,113 cases(70.6% )had one or more extra-cranial infectious foci,and 18 cases(11.3% )had underlying diseases.The most common clinical symptoms were fever(147 cases,91.9% ),followed by lethargy(98 cases,61.3% )and vomiting(61 cases,38.1% ).Sixty-nine cases(43.1% )experienced intracranial complications during hospitalization,with subdural effusion and/or empyema being the most common complication[43 cases(26.9% )],followed by hydrocephalus in 24 cases(15.0% ),brain abscess in 23 cases(14.4% ),and cerebral hemorrhage in 8 cases(5.0% ).Subdural effusion and/or empyema and hydrocephalus mainly occurred in children under 1 year old,with rates of 91% (39/43)and 83% (20/24),respectively.SP strains exhibited complete sensitivity to vancomycin(100% ,75/75),linezolid(100% ,56/56),and meropenem(100% ,6/6).High sensitivity rates were also observed for levofloxacin(81% ,22/27),moxifloxacin(82% ,14/17),rifampicin(96% ,25/26),and chloramphenicol(91% ,21/23).However,low sensitivity rates were found for penicillin(16% ,11/68)and clindamycin(6% ,1/17),and SP strains were completely resistant to erythromycin(100% ,31/31).The rates of discharge with cure and improvement were 22.5% (36/160)and 66.2% (106/160),respectively,while 18 cases(11.3% )had adverse outcomes.Conclusions Pediatric PM is more common in children aged 3 months to under 3 years.Intracranial complications are more frequently observed in children under 1 year old.Fever is the most common clinical manifestation of PM,and subdural effusion/emphysema and hydrocephalus are the most frequent complications.Non-culture detection methods for cerebrospinal fluid can improve pathogen detection rates.Adverse outcomes can be noted in more than 10% of PM cases.SP strains are high sensitivity to vancomycin,linezolid,meropenem,levofloxacin,moxifloxacin,rifampicin,and chloramphenicol.[Chinese Journal of Contemporary Pediatrics,2024,26(2):131-138]

Objective To explore training programs for pharmacists in retail pharmacies to implement medication therapy management services for patients with chronic diseases.Methods Combined with national conditions in China,the expert consultation method was used to establish a training program for pharmacists in retail pharmacies on chronic disease medication therapy management in terms of curriculum setting,teaching mode,and teaching assessment,and to implement the training.Qualitative interviews were conducted to gain an in-depth understanding of pharmacists'evaluations and suggestions on the training program.Results The training curriculum covered practice skills of pharmaceutical care and pharmacotherapeutics.The teaching modes included online learning and Q&A,case writing,role-playing and standardized patient case practices,and teaching assessment was conducted through knowledge quizzes,objective structured clinical exams,practice tests and questionnaires.181 pharmacists attended and completed the training,and the score of their overall satisfaction with the training program was 4.7(out of a maximum score of 5.0).Through the training,pharmacists'knowledge and skill levels in medication therapy management as well as attitudes,confidence and perceptions of practice were significantly improved and demonstrated better pharmacy practice abilities.Most pharmacists expressed their learning needs for disease-based pharmacy service model and communication skills training with patients in qualitative interviews.Conclusion A training program suitable for retail pharmacists to improve the comprehensive ability of chronic disease medication therapy management has initially formed,and disease-based doctor-patient communication ability and pharmaceutical care process training should become the focus of learning in medication therapy management service ability of retail pharmacists.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

The COVID-19 epidemic has spread to the whole world for three years and has had a serious impact on human life, health and economic activities. China's epidemic prevention and control has gone through the following stages: emergency unconventional stage, emergency normalization stage, and the transitional stage from the emergency normalization to the "Category B infectious disease treated as Category B" normalization, and achieved a major and decisive victory. The designated hospitals for prevention and control of COVID-19 epidemic in Tianjin has successfully completed its tasks in all stages of epidemic prevention and control, and has accumulated valuable experience. This article summarizes the experience of constructing a hospital infection prevention and control system during the "Category B infectious disease treated as Category A" period in designated hospital. The experience is summarized as the "Cluster" hospital infection prevention and control system, namely "three rings" outside, middle and inside, "three districts" of green, orange and red, "three things" before, during and after the event, "two-day pre-purification" and "two-director system", and "one zone" management. In emergency situations, we adopt a simplified version of the cluster hospital infection prevention and control system. In emergency situations, a simplified version of the "Cluster" hospital infection prevention and control system can be adopted. This system has the following characteristics: firstly, the system emphasizes the characteristics of "cluster" and the overall management of key measures to avoid any shortcomings. The second, it emphasizes the transformation of infection control concepts to maximize the safety of medical services through infection control. The third, it emphasizes the optimization of the process. The prevention and control measures should be comprehensive and focused, while also preventing excessive use. The measures emphasize the use of the least resources to achieve the best infection control effect. The fourth, it emphasizes the quality control work of infection control, pays attention to the importance of the process, and advocates the concept of "system slimming, process fattening". Fifthly, it emphasizes that the future development depends on artificial intelligence, in order to improve the quality and efficiency of prevention and control to the greatest extent. Sixth, hospitals need to strengthen continuous training and retraining. We utilize diverse training methods, including artificial intelligence, to ensure that infection control policies and procedures are simple. We have established an evaluation and feedback mechanism to ensure that medical personnel are in an emergency state at all times.

Objective: To investigate the distribution characteristics of trichlormethane in school drinking water in Jiangsu Province, and to evaluate the health risks and influencing factors of students exposed to trichlormethane, so as to provide a scientific basis for the disinfection and safety of school drinking water. Methods: A total of 315 schools (123 primary schools, 142 junior high schools, 20 high schools, and 30 universities) in Jiangsu Province were selected by a stratified sampling method. Water samples in the wet period (from July to September) of 2023 and in the dry period (from January to March) of 2024 in each school were collected, and 630 drinking water samples were collected. According to the Standard Examination Methods for Drinking Water (GB/T 5750-2023), drinking water samples were analyzed for trichlormethane, and the health risks of trichlormethane exposure in drinking water for students were assessed using the health risk assessment method recommended by US Environmental Protection Agency. The Kruskal-Wallis H rank sum test and Mann-Whitney U test were performed to analyze concentrations and health risks of trichlormethane in school drinking water in different groups. Results: The concentration of trichlormethane in school drinking water in Jiangsu Province was 8.9 (4.6, 14.0) μg/L. The carcinogenic risk of trichlormethane in school drinking water was 9.8×10 -6 (5.3×10 -6 , 1.7×10 -5 ), which was an acceptable low risk. The amount of drinking water per unit body weight and the concentration of trichlormethane in tap water samples were important factors affecting the carcinogenic risk in drinking water for students. Comparison of carcinogenic risks exposed to trichlormethane in drinking water were as follows:primary school students in lower grades had the highest risk of carcinogenesis, with a risk of 1.2×10 -5 , the wet period (1.3×10 -5 ) >the dry period (7.6×10 -6 ), river source water (1.0×10 -5 ) >lake source water (6.8×10 -6 ), liquid chlorine disinfection (1.1×10 -5 ) > sodium hypochlorite disinfection (9.3×10 -6 ), conventional treatment (1.4×10 -5 ) > advanced treatment (9.6×10 -6 ), with statistically significant differences ( Z=88.1, 3.7 , -3.2, -2.7, P <0.05). The non carcinogenic risk of trichlormethane in school drinking water was 1.4×10 -2 for less than 1, and the non carcinogenic risk was acceptable. Conclusions The carcinogenic and non carcinogenic risks of trichlormethane in school drinking water are acceptable in Jiangsu Province, and the primary school students in lower grades are key indicators for risk management of trichlormethane in drinking water. According to the characteristics of the source water, appropriate disinfection methods and water treatment processes are selected to reduce the content of trichlormethane and control health risk.
