The patient,a male newborn,was admitted to the hospital 2 hours after birth due to prematurity(gestational age 27+5 weeks)and respiratory distress occurring 2 hours postnatally.After admission,the infant developed fever and elevated C-reactive protein levels.On the fourth day after birth,metagenomic next-generation sequencing of cerebrospinal fluid indicated a positive result for Mycoplasma hominis(9 898 reads).On the eighth day,a retest of cerebrospinal fluid metagenomics confirmed Mycoplasma hominis(56 806 reads).The diagnosis of purulent meningitis caused by Mycoplasma hominis was established,and the antibiotic treatment was switched to moxifloxacin[5 mg/(kg·day)]administered intravenously for a total of 4 weeks.After treatment,the patient's cerebrospinal fluid tests returned to normal,and he was discharged as cured on the 76th day after birth.This article focuses on the diagnosis and treatment of neonatal Mycoplasma hominis purulent meningitis,introducing the multidisciplinary diagnosis and treatment of the condition in extremely preterm infants.[Chinese Journal of Contemporary Pediatrics,2024,26(4):432-436]

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.

AIM To explore the clinical effects of Supplemented Buzhong Yiqi Decoction on patients with HP-positive chronic atrophic gastritis of Spleen-Stomach Deficiency Pattern.METHODS One hundred and thirty-two patients were randomly assigned into control group(66 cases)for 12-week intervention of conventional treatment,and observation group(66 cases)for 12-week intervention of both Supplemented Buzhong Yiqi Decoction and conventional treatment.The changes in clinical effects,HP clearance rate,miR-32,TGF-β1,IL-6,PGⅠ,PGⅡ,EGF,somatostatin,gastrin,motilin,gastroscopy pathological score and TCM symptom score were detected.RESULTS The observation group demonstrated higher total effective rate and HP clearance rate than the control group(P<0.05).After the treatment,the two groups displayed decreased miR-32,TGF-β1,IL-6,gastroscopy pathological score,TCM symptom score(P<0.05),and increased PGⅠ,PGⅡ,EGF,somatostatin,gastrin,motilin(P<0.05),especially for the observation group(P<0.05).CONCLUSION For the patients with HP-positive chronic atrophic gastritis of Spleen-Stomach Deficiency Pattern,Supplemented Buzhong Yiqi Decoction can alleviate inflammation,regulate gastrointestinal hormone levels,improve symptoms,and enhance efficacy.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

OBJECTIVE: To review the research progress of the feasibility of a new treatment method for atrophic rhinitis (ATR) based on tissue engineering technology (seed cells, scaffold materials, and growth factors), and provide new ideas for the treatment of ATR. METHODS: The literature related to ATR was extensively reviewed. Focusing on the three aspects of seed cells, scaffold materials, and growth factors, the recent research progress of ATR treatment was reviewed, and the future directions of tissue engineering technology to treat ATR were proposed. RESULTS: The pathogenesis and etiology of ATR are still unclear, and the effectiveness of the current treatments are still unsatisfactory. The construction of a cell-scaffold complex with sustained and controlled release of exogenous cytokines is expected to reverse the pathological changes of ATR, promoting the regeneration of normal nasal mucosa and reconstructing the atrophic turbinate. In recent years, the research progress of exosomes, three-dimensional printing, and organoids will promote the development of tissue engineering technology for ATR. CONCLUSION Tissue engineering technology can provide a new treatment method for ATR.

【Objective】 To investigate the correlation of monocytes and high-density lipoprotein cholesterol ratio(MHR) and albumin with the severity of coronary artery lesions in patients with unstable angina pectoris. 【Methods】 We enrolled 342 patients with unstable angina pectoris. According to the Gensini score of their coronary angiography results, they were divided into Gensini≤ 20 group, 2040 group. The differences in biochemical indicators between the groups were compared, and the correlation between the different indicators and the Gensini score was analyzed. According to the MHR quartile grouping, there were differences between the comparison groups. LDL-C was divided into subgroups and then subjected to multifactor Logistic regression analysis. 【Results】 MHR differed significantly among low, moderate and high grade lesions (P<0.05). Subgroup analysis showed that in low LDL-C group, Gensini score was positively correlated with MHR(P<0.05), while in high LDL-C group, Gensini score was negatively correlated with albumin(P<0.05). Multivariate Logistic regression analysis showed that the MHR level of patients with high Gensini score was 102.375 times higher than that of patients with low Gensini score(P<0.05). In the group with high LDL-C, the serum albumin level in the group with low Gensini score was 1.431 times that in the group with high Gensini score and 1.218 times that in the group with moderate Gensini score(all P<0.05). 【Conclusion】 In patients with unstable angina pectoris, especially when LDL-C levels are not high, both high MHR and low serum albumin are independent risk factors for the severity of coronary artery disease.

【Objective】 To investigate the risk factors and predictive effectiveness of prostate imaging reporting and data system (PI-RADS) score for patients with clinically significant prostate cancer (CsPCa) whose PI-RADS score was 3, so as to provide evidence for the diagnosis and treatment. 【Methods】 The clinical and multi-parameter magnetic resonance imaging (mpMRI) data of 153 CsPCa patients treated during Jan.2017 and Dec.2021 whose PI-RADS score was 3 were retrospectively analyzed. With PI-RADS score of 3 as the independent risk factor for CsPCa, the other relevant independent risk factors in predicting CsPCa were evaluated. 【Results】 Univariate and multivariate analyses showed that prostate-specific antigen (PSA) density and apparent dispersion coefficient (ADC) were independent risk factors for the diagnosis of CsPCa (P<0.05). Analysis of receiver operating characteristic (ROC) curve showed that combined PSA density and ADC were more effective than PSA density and ADC alone (P<0.05). 【Conclusion】 The combination of PSA density and ADC can guide clinicians to identify high-risk CsPCa patients from patients with PI-RADS score of 3 points.

Objective: To evaluate snack consumption and the influencing factors associated with student participation in the Nutrition Improvement Program, and to provide a scientific basis for improving the program. Methods: Among the 50 monitoring counties that implemented the Compulsory Education Student Nutrition Improvement Program, two primary schools and two junior schools were randomly selected according to different food supply patterns (i.e., school, company, and mix). This study randomly selected one or two classes from each grade, which ranged from grade 3 to grade 9. A questionnaire, which addressed snack consumption and choice, was distributed to 27 374 students. Results: The findings revealed that 14.0% of students from poor rural areas in central and western regions consumed snacks two or more times per day, and 21.6% of students spent 3 yuan or more on snacks each day. The top three choices of snacks included fruit and vegetables (50.6%), biscuits and bread (50.1%), and puffed food (40.0%). Students who had mothers who worked outside the home, parents who worked outside the home, who consumed corporate meals, and who had access to a small shop on campus were more likely to consume snacks one or more times per day(OR=1.35，1.19，1.11，1.51，P<0.05). Conclusion The phenomenon of snack consumption among primary and middle school students from poor rural areas in central and western regions is common, and the selection of unhealthy snacks was identified as a problem. A health education system with comprehensive support and guidance from individuals, families, schools, and society should be established to guide students to opt for healthier snacks.

Objective: To evaluate temporal trend in food supply among pilot schools involved in the National Nutrition Improvement Program for Rural Compulsory Education Students (NNIPRCES). Methods: Ten percent of pilot schools were randomly selected and asked to report the information on food supplies. Daily intake of energy, carbohydrates and protein for each student were calculated and compared with the reference value in Nutrition Guidelines of School Meals (WS/T 554-2017). Results: Energy and protein supply increased among those pilot schools. The supply of energy increased from 1 566.5 kcal in 2012 to 1 927.4 kcal in 2017, protein increased from 49.0 g to 61.0 g. The energy ratio of fat increased from 31.9% to 34.9%, while energy ratio of carbohydrate decreased significantly (F=83.38, 128.36, 20.27 and 17.28, all P<0.05). The proportion of reasonable energy supply from carbohydrate and fat in 2017 were 17.5% and 26.8%, respectively. Conclusion The supply of energy and macronutrients in the pilot areas were unreasonable, more measures including dietary guide and monitoring need to be adopted to improve students nutrition status among rural areas.
