ObjectiveTo analyze the prevalence and influencing factors of overweight and obesity among primary school students in a community of Fengxian District, Shanghai, and to provide references for formulating prevention and control strategies against overweight and obesity. MethodsData on height and weight of all primary school students in a community in Fengxian District, Shanghai, in 2023 were obtained by physical examination, and 1 759 primary school students were included according to the entry criteria. Overweight and obesity were determined using body mass index (BMI). Additionally, a questionnaire survey was performed to 1 045 students to collect their demographic characteristics, dietary behaviors, dietary habits, sleep and physical activity information. Chi-square test and logistic regression analysis were used to analyze the influencing factors of overweight and obesity. ResultsIn 2023, among the 1 759 primary school students in the community in Fengxian District, 923 (52.47%) were male and 836 (47.53%) were female, with an overweight/obesity detection rate of 28.08%. The detection rate of overweight and obesity was 33.37% in males and 22.25% in females, which was significantly higher in males than that in females (χ²=26.845, P<0.001). Students aged 10‒12 years had a higher overweight/obesity detection rate (32.55%) than those aged 6‒<10 years (26.53%), and the difference was statistically significant (χ²=10.925, P<0.001). Logistic regression analysis revealed that being female, with young age, parental education level of bachelor’s degree and above, a high global dietary recommendation healthy (GDR-healthy) score, preference for vegetables and sweeter home-cooked meals, and a slow eating speed were negatively correlated with overweight/obesity. Whereas, parental overweight and obesity, binge eating, and a faster eating pace than same-age, same-gender peers may be positively correlated with overweight/obesity. ConclusionThe detection rate of overweight and obesity among primary school students in the community in Fengxian District of Shanghai is higher than the national level. Gender, age, parental BMI, parental education level, dietary behaviors and habits are the main influencing factors of overweight/obesity among primary school students.

Objective To investigate the clinical efficacy of CT-guided drilling,hematoma aspiration and drainage for senile cerebellar hemorrhage.Methods A retrospective analysis was performed on 89 very old patients(75-89 years old)with cerebellar hemorrhage admitted to our hospital from January 2016 to December 2022.According to their wishes,different surgical treatments were adopted,and thus they were divided into puncture group(42 cases,CT-guided drilling,aspi-ration and drainage for hematoma)and craniotomy group(47 cases,craniotomy).GCS,preopera-tive hematoma volume,length of ICU stay,postoperative complications,mortality rate and the mRS score in 3 months postoperatively in the survival were compared between the 2 groups.Re-sults There were no significant differences in age,male ratio,GCS score,preoperative hematoma volume,recurrence rate at 24 h postoperatively and mortality rate at 3 months postoperatively be-tween 2 groups(P＞0.05).The puncture group had significantly shorter length of ICU stay(7.10±1.43 dvs 8.87±1.39 d,P=0.000)and lower intracranial infection rate(4.76％vs 19.15％,P=0.040)than the craniotomy group.In 3 months of follow-up after surgery,the rate of good mRS score was higher in the puncture group than the craniotomy group,and the mRS score was lower in the former group than the latter one(P＜0.05).Conclusion CT-guided drilling,aspiration and drainage for hematoma can reduce the infection rate and improve the prognosis,and is an effective approach in the treatment of patients over 75 years old with cerebellar hemorrhage.

Background/Aims: To evaluate the causal correlation between complement components and non-viral liver diseases and their potential use as druggable targets. Methods: We conducted Mendelian randomization (MR) to assess the causal role of circulating complements in the risk of non-viral liver diseases. A complement-centric protein interaction network was constructed to explore biological functions and identify potential therapeutic options. Results: In the MR analysis, genetically predicted levels of complement C1q C chain (C1QC) were positively associated with the risk of autoimmune hepatitis (odds ratio 1.125, 95% confidence interval 1.018–1.244), while complement factor H-related protein 5 (CFHR5) was positively associated with the risk of primary sclerosing cholangitis (PSC;1.193, 1.048– 1.357). On the other hand, CFHR1 (0.621, 0.497–0.776) and CFHR2 (0.824, 0.703–0.965) were inversely associated with the risk of alcohol-related cirrhosis. There were also significant inverse associations between C8 gamma chain (C8G) and PSC (0.832, 0.707–0.979), as well as the risk of metabolic dysfunction-associated steatotic liver disease (1.167, 1.036–1.314). Additionally, C1S (0.111, 0.018–0.672), C7 (1.631, 1.190–2.236), and CFHR2 (1.279, 1.059–1.546) were significantly associated with the risk of hepatocellular carcinoma. Proteins from the complement regulatory networks and various liver diseaserelated proteins share common biological processes. Furthermore, potential therapeutic drugs for various liver diseases were identified through drug repurposing based on the complement regulatory network. Conclusions Our study suggests that certain complement components, including C1S, C1QC, CFHR1, CFHR2, CFHR5, C7, and C8G, might play a role in non-viral liver diseases and could be potential targets for drug development.

Objective To explore the efficacy of the retrosigmoid sinus approach through the cerebellopontine angle in the treatment of pontine hemorrhage.Methods A retrospective analysis was performed on 108 patients with pontine hemorrhage in Kaifeng Central Hospital from January 2016 to June 2022.They were divided into two groups according to the treatment methods,the conservative treatment group and the craniotomy treatment group(transcerebellopontine angle sigmoid sinus posterior approach).There were 94 cases in the conservative treatment group and 14 cases in the surgical treatment group.First analysis was conducted to examined whether there are differences in gender,age,Glasgow Coma Score(GCS)on admission,bleeding volume,comorbidities and complications between the two groups.Additional analysis was performed to analyze modified Rankin(modified Rankin scale,mRS)score and mortality rate after three month follow-up in case there was no significant difference at first analysis.Results There were no statistical differences in gender,age,Glasgow Coma Score(GCS)on admission,bleeding volume,comorbidities and complications between the two groups.After 3 months of follow-up,49 patients died in the conservative treatment group and 3 patients in the craniotomy treatment group.The mortality rates of the two groups were 52.1％and 21.4％respectively(χ2=4.600,P<0.05)).There was a statistical difference in the mortality rate between the two groups,and the mortality rate of the craniotomy treatment group was significantly lower than that of the conservative group.The modified Rankin score was 4(3,5)in the conservative treatment group and 3(2,3)in the craniotomy group(Z=-2.994,P<0.01).The modified Rankin score in the craniotomy group was lower than that in conservative treatment group after 3 months.Conclusion Microsurgery through the cerebellopontine angle retrosigmoid sinus approach to treat pontine hemorrhage can significantly reduce patient mortality and improve prognosis and is an effective surgical treatment method.

Critical ultrasonography is widely used in ICU and has become an indispensable tool for clinicians. However, besides operator-dependency of critical ultrasonography, lack of standardized training mainly result in the physicians′ heterogenous ultrasonic skill. Therefore, standardized training as well as strict quality control plays the key role in the development of critical ultrasonography. We present this quality control standards to promote better development of critical ultrasonography.

The epidemic of coronavirus disease 2019 (COVID-19) puts higher demands on critical care medicine. Lots of studies have been conducted to solve COVID-19-related problems. Therefore, we reviewed the annual progress for COVID-19-related issues including antivirals threapies, respiratory support and immunomodulatory therapies and other critical issues, including the effect of antibiotic on mitochondrial damage and its relationship with sepsis, the goal and direction of antimicrobial de-escalation, drug prophylaxis of constipation, bleeding in gastrointestinal disorders and management of critical illness in the informalization era and so on. We hope to provide reference for clinical and scientific research work of the intensivists.

Objective : The purpose of this study was to investigate the relevant social and environmental factors affecting the occurrence of periodontal diseases during pregnancy in pregnant women and to analyze the influence of the periodontal status of women in the second trimester of pregnancy on small for gestational age (SGA) delivery. Methods: A total of 215 pregnant women were enrolled in this study in the Department of Periodontology of the West China Hospital of Stomatology of Sichuan University from May 2015 to May 2018. Periodontal parameters, such as bleeding on probing (BOP), probing depth (PD) and clinical attachment loss (CAL), were recorded at 16-24 weeks of gestational age. Subjects were divided into the periodontitis (n=32) group, gingivitis (n=171) group and periodontally healthy (n=12) group according to their periodontal conditions. With the patient′s informed consent, the patient decided whether to receive periodontal treatment. Basic and socioeconomic information was collected through questionnaires. After delivery, subjects were divided into the SGA group and non-SGA group according to their birth results. The periodontal clinical indicators, questionnaire results and delivery results were compared among the groups. Results : The mean PD (P=0.005, r=-0.192) and BOP% (P=0.003, r=-0.199) were negatively correlated with economic income. The family income in the periodontitis group was significantly lower than that in the healthy group and the gingivitis group (P < 0.05). The flossing use rate was significantly higher in the healthy group than that in the gingivitis group (P < 0.05). A total of 106 pregnant women received scaling and root planing, while 109 patients only received oral hygiene instruction. After delivery, SGA occurred in 23 cases (10.7%), and there were no significant difference in SGA incidence among the three groups (P > 0.05). PD ≥ 5 mm% and PD ≥ 4 mm% (P < 0.05) were significantly higher in the SGA group than in the non-SGA group. There was no significant difference in SGA incidence between the treated group and the untreated group (P > 0.05). Conclusion Family income and dental flossing use have an impact on the incidence of periodontal diseases during pregnancy. The severity of periodontitis in pregnant women is correlated with the incidence of SGA.

Severe patients with coronaviras disease 2019 (COVID-19) are characterized by persistent lung damage, causing respiratory failure, secondary circulatory changes and multiple organ dysfunction after virus invasion. Because of its dynamic, real-time, non-invasive, repeatable and other advantages, critical ultrasonography can be widely used in the diagnosis, assessment and guidance of treatment for severe patients. Based on the recommendations of critical care experts from all over the country who fight against the epidemic in Wuhan, this article summarizes the guidelines for the treatment of COVID-19 based on critical ultrasonography, hoping to provide help for the treatment of severe patients. The recommendations mainly cover the following aspects: (1) lung ultrasound in patients with COVID-19 is mainly manifested by thickened and irregular pleural lines, different types of B-lines, shred signs, and other consolidation like dynamic air bronchogram; (2) Echocardiography may show right heart dysfunction, diffuse cardiac function enhancement, stress cardiomyopathy, diffuse cardiac depression and other multiple abnormalities; (3) Critical ultrasonography helps with initiating early treatment in the suspect patient, screening confirmed patients after intensive care unit admission, early assessment of sudden critical events, rapid grading assessment and treatment based on it; (4) Critical ultrasonography helps to quickly screen for the etiology of respiratory failure in patients with COVID-19, make oxygen therapeutic strategy, guide the implementation of lung protective ventilation, graded management and precise off-ventilator; (5) Critical ultrasonography is helpful for assessing the circulatory status of patients with COVID-19, finding chronic cardiopulmonary diseases and guiding extracorporeal membrane oxygenation management; (6) Critical ultrasonography contributes to the management of organs besides based on cardiopulmonary oxygen transport; (7) Critical ultrasonography can help to improve the success of operation; (8) Critical ultrasonography can help to improve the safety and quality of nursing; (9) When performing critical ultrasonography for patients with COVID-19, it needs to implement three-level protection standard, pay attention to disinfect the machine and strictly obey the rules from nosocomial infection. (10) Telemedicine and artificial intelligence centered on critical ultrasonography may help to improve the efficiency of treatment for the patients with COVID-19. In the face of the global spread of the epidemic, all we can do is to share experience, build a defense line, We hope this recommendations can help COVID-19 patients therapy.

Objective: To investigate the changes of B cell-activating factor (BAFF) and a proliferation- inducing ligand (APRIL) in serum of children with Henöch- Schönlein purpura nephritis (HSPN), and to explore their role in the pathogenesis of children HSPN. Methods: A total of 28 children with HSPN who were before treatment were selected in Department of Pediatrics Nephrology and Rheumatology, Shengjing Hospital of China Medical University from November 2017 to August 2018.Sixteen children with Henöch-Schönlein purpura were selected as HSP group, and 20 healthy children were selected as healthy control group.Followed the HSPN guideline to cure the patients for 6-8 weeks.The clinical data were collected.Serum levels of BAFF and APRIL were measured by adopting enzyme-linked immunosorbent assay (ELISA). Results: (1)Changes of serum BAFF level: the serum levels of BAFF in HSPN children were significantly lower than those in the HSP group and the healthy control group[ HSPN group (0.652±0.360) μg/L, HSP group (1.276±0.459) μg/L, healthy control group (1.285±0.299) μg/L, F=17.519, P=0.000]. Moreover, the serum levels of BAFF in before treatment were significantly lower than those in after treatment [before treatment (0.652±0.360) μg/L, after treatment (0.860±0.262) μg/L, P<0.05). However, there were no significant di-fferences in the serum levels of BAFF between HSP group and healthy control group (P>0.05). (2)Changes of serum APRIL level: the serum levels of APRIL in HSPN and HSP children were both significantly higher than those in healthy control group, but there were no marked differences between the 2 groups [HSPN group (2.285±1.015) μg/L, HSP group (2.609±1.264) μg/L, healthy control group (1.677±0.118) μg/L, F=3.647, P=0.016]. There were no significant differences in the serum levels of APRIL between before treatment and after treatment [ before treatment (2.285±1.015) μg/L, after treatment (2.042±0.695) μg/L, P>0.05]. (3)Pearson correlation analysis results showed that the serum levels of BAFF were negatively correlated with 24 h urinary protein, urinary microalbumin, and urine red blood cell count (r=-0.587, -0.608, -0.515, all P<0.05). The serum levels of APRIL were positively correlated with serum IgA(r=0.588, P<0.05). Conclusions The level of serum BAFF decreased and APRIL increased in children with HSPN, which was related to the degree of renal involvement.It suggests that BAFF and APRIL may be related to the pathogenesis of HSPN in children.

Transesophageal echocardiography(TEE) is valuable in intensive care unit (ICU) because its application meets the requirements of diagnosis and treatment of critically ill patients.However, the current application has not fully adapted to the specialty of critical care. TEE could be more valuablein ICU when used with a new way that under the guidance of the theory of critical care and embedded into the treatment workflow. We have expanded and improved the application of traditional TEE and integrated the concept of critical care, established the concept of transesophageal echocardiography for critical care (TEECC). Chinese Critical Ultrasound Study Group (CCUSG) organized experts in the area to form the consensus based the previous studiesand the long term practice of critical care ultrasound and TEE, aiming at clarifying the nature and characteristics of TEECC, promoting the rational and standardized clinical application and the coming researches.The consensus of Chinese experts on clinical application of TEECC (2019) were 33 in total, of whichthe main items were as follows: (1) TEECC is a significant means, which is expanded and improved from the traditional transesophageal echocardiography according to characteristics of critically ill patients and is applied in ICU based on critically clinical scenarios and requirements by the critical care physician, to promote visualized, refined and precisely management of critically ill patients.(2) TEE possesses distinctive superiority in implementation in ICU. It has characteristics of images with good quality, operations with good stability and low-dependent of operators, monitoring with continuity, and visualization with all-dimensional and detail of heart and blood vessels.(3)As a means of refined monitoring that could resulted in precise diagnosis and treatment, TEECC expands the dimension of intensive monitoring and improves the performance of critical care. (4) Indications of TEECC application include clinical etiological searching and invasive procedures guiding when it acted as a traditional role; and also refined hemodynamic monitoring based on critical care rationale and over-all management under specific critical clinical scenarios. (5) TEE and TTE assessments are complementary; they are not alternative. Integrated assessment of TTE and TEE is required under many critical clinical scenarios.(6) TEE should be a necessary configuration in ICU. (7) All-round and significant information regarding to the mechanism of acute circulatory disorders can be provided by TEECC; it is a non-substitutable means of identifying the causes of shock under some special clinical scenarios. (8) Focal extracardiac hematoma can be accurately and rapidly detected by TEE in patients with open-thoracic cardiac surgery or severe chest trauma when highly suspected pericardial tamponade.(9) The priority of pathophysiologic mechanism of septic shock can be rapidly and accurately identified by TEE; even if its pathophysiological changes are complex, including hypovolemia and/or vasospasm and/or left and right heart dysfunction. (10) Causes of hemodynamic disorders can be rapidly and qualitatively evaluated so that the orientation of treatment can be clarified by TEECC. (11) A full range of quantitative indicators for refined hemodynamic management in critically ill patients can be provided by TEECC. (12) TEECC helps to accurately assess volume status and predict fluid responsiveness.(13) TEECC is specially suitable for accurate quantitative assessment of cardiac function.(14) Mini TEE provides long-term continuous hemodynamic monitoring. (15) Standard views are easy to be acquired by TEECC, which is a premise for accurate and repeatable measurements, and a guarantee for assessment of effect and risk of therapy. (16) Compared with invasive hemodynamic monitoring, TEECC is minimally invasive, with low infection risk and high safety.(17) In patients with acute cor pulmonale (ACP) under condition of right ventricular dysfunction and low cardiac output, TEECC is a key tool for assessment. (18) TEECC should be implemented actively when suspicious of left to right shunt in critically ill patients who occurred hypotension that hard to explain the cause. (19) TEECC should be implemented actively when suspicious of right to left shunt in critically ill patients who occurred hypoxemia that hard to explain the cause. (20) TEECC is preferred in hemodynamics monitoring under prone position of ventilated patients.(21) TEECC is an imperative means to achieve over-all management of extracorporeal membrane oxygenation (ECMO) therapy, especially for all-round hemodynamic monitoring. (22) Three basic views is recommended to be used to simplify TEE assessment during cardiac arrest so that reversible causes could be identified, and resuscitation could be guided. (23) The flow related echodynamic evaluation (TEECC-FREE) workflow is preferred in refined hemodynamics monitoring and therapy. (24) Simple workflow of TEECC could be implemented in special critical clinical scenarios. (25) Application of TEECC is highly secure; however, impairments of procedure should also be alert by operators. (26) Pitfalls in application of TEE should be paid attention to by the critical care physician. (27) Timely and rationally application of TEECC is in favor of diagnosis and treatment of critically ill patients and may improve the prognosis.
