Objective To investigate the correlation of triacylglycerol glucose(TyG)index,monocyte to high-density lipoprotein cholesterol ratio(MHR)with coronary artery disease and myocardial ischemia degree in coronary heart disease(CHD),and to analyze the two Predictive value of coronary artery disease and myocardial ischemia degree.Methods CHD patients from the 920th Hospital of the Chinese People's Liberation Army Joint Logistics Support Force from January 2019 to January 2022 were selected as the study group(n = 150),and healthy physical examination subjects from the same period were selected as the control group(n = 75).The TyG index and MHR of the two groups were compared and analyzed.The extent of coronary artery disease was evaluated based on the Gensini score,and the TyG index and MHR of patients with different coronary lesions and myocardial ischemia were compared,and their correlation with Gensini score and myocardial ischemia was analyzed.The predictive value of TyG index,MHR,and the combined detection of both for coronary lesions and myocardial ischemia was evaluated using receiver operating characteristic(ROC)curves and area under the curve(AUC).Results The TyG index and MHR of the study group were(4.12±0.35)and(0.26±0.08)×109,respectively,which were higher than those of the control group(4.94±0.55)and(0.43±0.12)×109,and the TyG index and MHR of severe coronary artery disease>moderate coronary artery disease>mild coronary artery disease,acute myocardial infarction TyG index,MHR>unstable angina pectoris>stable angina pectoris(P<0.05);TyG index and MHR were positively correlated with Gensini score(r = 0.621,0.635,P<0.05),and positively correlated with the severity of myocardial ischemia(r = 0.617,0.642,P<0.05).The AUC of TyG index and MHR for the joint identification of mild coronary artery disease and moderate coronary artery disease was 0.917,which was greater than the AUCs of 0.749 and 0.832 for the two conditions individually.The AUC of TyG index and MHR for the joint identification of mild to moderate coronary artery disease and severe coronary artery disease was 0.935,which was greater than the AUCs of 0.770 and 0.767 for the two conditions individually(P<0.05).The AUC of TyG index and MHR for the joint identification of stable angina pectoris and unstable angina pectoris was 0.922,which was greater than the AUCs of 0.812 and 0.824 for the two conditions individually.The AUC of TyG index and MHR for the joint identification of stable angina pectoris,unstable angina pectoris,and acute myocardial infarction was 0.913,which was greater than the AUCs of 0.708 and 0.714 for the two conditions individually(P<0.05).Conclusions TyG index and MHR are positively correlated with Gensini score and myocardial ischemia degree.The combined detection of the two has a higher application value in the evaluation of coronary artery disease and myocardial ischemia degree.

BACKGROUND:With the increase of patients with cubital tunnel syndrome,ulnar groove plasty does not affect the normal anatomical structure and distribution of the ulnar nerve,which is one of the main surgical procedures for the treatment of cubital tunnel syndrome.3D printing combined with ulnar groove plasty can more accurately position the expansion depth and width of the ulnar groove to avoid some surgical complications. OBJECTIVE:To investigate the effect of 3D printing technology combined with ulnar groove plasty on nerve electrophysiology and prognosis in patients with cubital tunnel syndrome. METHODS:A total of 70 patients with moderate and severe cubital tunnel syndrome who were treated in Cangzhou Integrated Traditional Chinese and Western Medicine Hospital from March 2020 to March 2022 were selected as the study subjects.They were divided into two groups,with 35 cases in each group.The control group underwent traditional ulnar groove plasty.The observation group underwent 3D printing technology combined with ulnar groove plasty.The patients were followed up for 3 months.The clinical efficacy,latency,amplitude of compound muscle action potential of abductor pollicis brevis of the affected limb and ulnar nerve motor conduction velocity,grip strength on the affected side,pinch strength of the middle and thumb fingers,S-W monofilament of the little finger,two-point discrimination of the little finger,and Disabilities of the Arm,Shoulder and Hand Questionnaire score were compared between the two groups. RESULTS AND CONCLUSION:(1)Compared with the control group(74%),the excellent and good rate was significantly higher in the observation group(91%)(P<0.05).(2)Compared with pre-treatment,the latency of compound muscle action potential of abductor pollicis brevis of affected limb was significantly shorter and the wave amplitude and ulnar nerve motor conduction velocity were significantly higher in the two groups after treatment.The latency was significantly shorter and the wave amplitude and ulnar nerve motor conduction velocity were significantly higher in the observation group than those in the control group(P<0.05).(3)Compared with pre-treatment,the grip strength,middle finger and thumb pinch strength of the affected side,S-W monofilament of the little finger and two-point discrimination of the little finger were significantly decreased in the two groups after treatment.The grip strength,middle finger and thumb pinch strength on the affected side were greater,S-W monofilament of the little finger and two-point discrimination of the little finger were significantly smaller in the observation group than those in the control group(P<0.05).(4)Compared with pre-treatment,the Disabilities of the Arm,Shoulder and Hand Questionnaire scores of the two groups were significantly reduced after treatment,and the Disabilities of the Arm,Shoulder and Hand Questionnaire scores of the observation group were significantly lower than those of the control group(P<0.05).(5)It is concluded that 3D printing technology combined with ulnar groove plasty in the treatment of cubital tunnel syndrome can effectively improve its clinical efficacy,promote the neurophysiological recovery of patients,and enhance the function of fingers and upper limbs,which has high clinical application value.

China has classified the Corona Virus Disease 2019(COVID-19) as a statutory category B infectious disease and managed it according to Category B since January 8, 2023.In view that Omicron variant is currently the main epidemic strain in China, in order to guide the treatment of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) infection in children with the times, refer to the Diagnosis and Treatment Protocol for Novel Coronavirus Infection (Trial 10 th Edition), Expert Consensus on Diagnosis, Treatment and Prevention of Novel Coronavirus Infection in Children (Fourth Edition) and the Diagnosis and Treatment Strategy for Pediatric Related Viral Infections.The Expert Consensus on the Diagnosis, Treatment and Prevention of Novel Coronavirus Infection in Children (Fifth Edition) has been formulated and updated accordingly on related etiology, epidemiology, pathogenic mechanism, clinical manifestations, auxiliary examination, diagnosis and treatment, and added key points for the treatment of COVID-19 related encephalopathy, fulminating myocarditis and other serious complications for clinical reference.

Monkeypox is a zoonotic disease.Previous studies have shown that children are vulnerable to monkeypox and are also at high risk for severe disease or complications.In order to improve pediatricians′ understanding of monkeypox and achieve early detection, early diagnosis, early treatment and early disposal, the committee composed of more than 40 experts in the related fields of infectious diseases, pediatrics, infection control and public health formulate this expert consensus, on the basis of the latest clinical management and infection prevention and control for monkeypox released by the World Health Organization (WHO), the guidelines for diagnosis and treatment of monkeypox (version 2022) issued by National Health Commission of the People′s Republic of China and other relevant documents.During the development of this consensus, multidisciplinary experts have repeatedly demonstrated the etiology, epidemiology, transmission, clinical manifestations, laboratory examinations, diagnosis and differential diagnosis, treatment, discharge criteria, prevention, case management process and key points of prevention and control about monkeypox.

Since December 2019, severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) infections have raged globally for more than 2 years.China has always adopted scientific and effective prevention and control measures to achieved some success.However, with the continuous variation of SARS-CoV-2 cases and imported cases from abroad, the prevention and control work has become more difficult and complex.With the variation of the mutant strain, the number of cases in children changed, and some new special symptoms and complications were found, which proposed a new topic for the prevention and treatment of SARS-CoV-2 infection in children in China.Based on the third edition, the present consensus according to the characteristics of the new strain, expounded the etiology, pathology, pathogenesis, and according to the clinical characteristics and experience of children′s cases, and puts forward recommendations on the diagnostic criteria, laboratory examination, treatment, prevention and control of children′s cases for providing reference for further guidance of effective prevention and treatment of SARS-CoV-2 infection in children in China.

Objective:To analyze the health fitness and its influencing factors among urban elderly residents in Lanzhou city.Methods:A multi-stage sampling method was used to survey urban elderly residents in Lanzhou city with self-designed questionnaire from July 17th to August 3rd, 2020. The questionnaire included general information, life habits and Healthy Fitness Measurement Scale Version 1.0 (HFMS V 1.0), a total of 1 124 questionnaires were distributed and 1 124 were collected, including 1 043 valid questionnaires (92.8%). The HFMS V 1.0 was scored with Likert 5-point scale, positive and negative scoring method. The health fitness status of the subjects was divided into low, medium and high levels according to the norms of HFMS V 1.0 for Chinese urban elderly residents. The influencing factors were analyzed by using the chi-square test and ordinal logistic regression.Results:The conversion score of HFMS V 1.0 for the urban elderly residents in Lanzhou city was 61.99±14.20, and the physical fitness score was the lowest (57.84±16.98); of the 1 043 subjects, 332 (31.83%), 360 (34.52%) and 351 (33.65%) subjects were classified with low, medium, and high health fitness levels, respectively. Chronic diseases and poor dietary habits were the risk factors for the health fitness of urban elderly residents in Lanzhou city (both P<0.05); more adequate sun exposure, physical exercise, sufficient sleep, high self-health concern and high frustration quotient were protective factors for health fitness in those subjects (all P<0.05). Conclusion:The overall level of health fitness in urban elderly residents in Lanzhou city is moderate, and chronic disease, dietary habits, sun exposure, physical exercise, length of sleep, self-health concern and frustration quotient are the main influencing factors.

At present, severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)infection is still rampant worldwide.As of September 10, 2021, there were about 222 million confirmed cases of corona virus disease 2019(COVID-19)and more than 4.6 million deaths worldwide.With the development of COVID-19 vaccines and the gradual vaccination worldwide, the increasing number of cases in children and unvaccinated young people has drawn attention.According to World Health Organization surveillance data, the proportion of COVID-19 infection cases in children gradually increased, and the proportion of cases in the age groups of under 5 years and 5-14 years increased from 1.0% and 2.5% in January 2020 to 2.0% and 8.7% in July 2021, respectively.At present, billions of adults have been vaccinated with various COVID-19 vaccines worldwide, and their protective effects including reducing infection and transmission, reducing severe disease and hospitalization, and reducing death, as well as high safety have been confirmed.Canada, the United States, Europe and other countries have approved the emergency COVID-19 vaccination in children and adolescents aged 12 to 17 years, and China has also approved the phased vaccination of COVID-19 vaccination in children and adolescents aged 3 to 17 years. For smooth advancement and implementation of COVID-19 vaccination in children, academic institutions, including National Clinical Research Center for Respiratory Diseases, National Center for Children′s Health, and The Society of Pediatrics, Chinese Medical Association organized relevant experts to reach this consensus on COVID-19 vaccination in children.

Severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)infection is still worldwide.As a vulnerable group, severe and dead pediatric cases are also reported.Under this severe epidemic situation, children should be well protected.With the widespread vaccination of SARS-CoV-2 vaccine in adults, the infection rate have decreased.Therefore, SARS-CoV-2 vaccine inoculation for children groups step by step is of great significance to the protection of children and the prevention and control of corona virus disease 2019(COVID-19) as a whole.But the safety of children vaccinated with SARS-CoV-2 vaccine is a main concern of parents.Therefore, in order to ensure the safety of vaccination and the implementation of vaccination work, National Clinical Research Center for Respiratory Diseases, National Center for Children′s Health and the Society of Pediatrics, Chinese Medical Association organized experts to interpret the main issue of parents about SARS-CoV-2 vaccine for children, in order to answer the doubts of parents.

Objective:To evaluate the application of metagenomic next-generation sequencing (mNGS) in the diagnosis of osteoarticular infection.Methods:The clinical data of 37 inpatients aged 32-90 year with osteoarticular infection admitted in the Department of Spine Surgery of Qingdao Chest Hospital from January to December 2019 were retrospectively analyzed. There were 31 cases of spine infection and 6 cases of other joint infection. The tissue samples were obtained from the infected sites through puncture or surgical approach in all patients. The tissue samples were subjected to routine culture of mycobacteria, aerobic bacteria and anaerobic bacteria, respectively. The gene amplification and mNGS were performed for detection of mycobacterium tuberculosis DNA (MTB-DNA). The chi-square test or Fisher’s exact test were used to compare the detection rates of pathogen and simple bacterial infection between mNGS and conventional culture. The conventional culture, mNGS and MTB-DNA amplification detection were performed for all samples; with clinical diagnosis as the gold standard, the diagnostic values of 3 methods were evaluated with receiver operating characteristic curve (ROC). Paired sample t test was used to compare white blood cell(WBC) count, erythrocyte sedimentation rate, C-reactive protein of patients before and after treatment. P<0.05 was considered statistically significant. Results:The pathogens were detected by mNGS for 42 times: bacteria for 39 times (92.8%), fungi for twice (4.8%) and Kirks body for once (2.4%). Among 37 patients there were 29 cases of pure bacterial infection (78.4%), 2 cases of pure fungi infection (5.4%), 1 case of pure Kirks body infection (2.7%), and 5 cases of mixed infection of two or more pathogens (13.5%). The detection rates of mNGS and conventional culture were 100.0% (37/37) and 67.6% (25/37), respectively ( χ2=13.987, P<0.05). The detection rates of mNGS and conventional culture in 29 patients with pure bacterial infection were 100.0% (29/29) and 69.0% (20/29), respectively ( χ2=16.913, P<0.05). The area under the ROC curve (AUC) of conventional culture, mNGS, and MTB-DNA in the diagnosis of osteoarticular tuberculosis infection was 0.958 (95% CI: 0.866-1.000, P<0.05), 1.000 (95% CI: 1.000-1.000, P<0.05) and 0.958 (95% CI: 0.866-1.000, P<0.05). All the 37 patients were treated with anti-infective drugs according to the results of mNGS and conventional culture. Among them, 28 patients received surgical intervention. The patients were followed up until April 30, 2020, 1 patient died. After 3 months of follow-up, the WBC count, erythrocyte sedimentation rate and C-reactive protein were (5.5±1.5)×10 9/L, (41±38)mm/h and (5.0±4.6) mg/L, respectively, which were lower than those before anti-infection treatment [(8.0±2.9)×10 9/L, (79±42)mm/h and(63±52)mg/L] ( t=6.536, 8.302 and 6.373, all P<0.05). Conclusion:The metagenomic next-generation sequencing may have important clinical value in the differential diagnosis of osteoarticular infection.
