ABSTRACT
Objective:To explore the consistency of MRI fast field echo resembling a CT using restricted echo-spacing (FRACTURE) and CT in the evaluation of knee and ankle bone changes.Methods:From November 2020 to November 2021, seventeen patients who underwent CT and MRI FRACTURE examinations of knee joint or ankle joint in the First Affiliated Hospital of Dalian Medical University were retrospectively collected, including 14 patients with knee joint examinations and 3 patients with ankle joint examinations. According to the number of joint components, 80 components were included, including 14 for femur and patella, 17 for tibia and fibula, and 3 for talus, scaphoid, medial cuneiform, medial cuneiform, lateral cuneiform and calcaneus, respectively. The fracture, hyperosteogeny, and bone destruction of the joint bones were evaluated by two observers using CT and FRACTURE images, respectively. Kappa test was used to analyze the consistency of CT and FRACTURE images between observers in the evaluation of joint bone lesions.Results:The Kappa values (95%CI) of the consistency evaluation of fracture, hyperosteogeny, and bone destruction by CT and FRACTURE images were 0.925 (0.823-1.027), 0.905 (0.799-1.011) and 0.895(0.752-1.038) respectively for observer 1, and were 0.963 (0.892-1.034), 0.933 (0.843-1.023) and 0.886 (0.731-1.041) respectively for observer 2. The Kappa values (95%CI) of the consistency evaluation of fracture, hyperosteogeny, and bone destruction by observers 1 and 2 via CT images were 1.000 (1.000-1.000), 0.937(0.851-1.023) and 0.945 (0.839-1.051) respectively, and that by FRACTURE images were 0.962 (0.888-1.036), 0.966 (0.899-1.033) and 0.836 (0.656-1.016) respectively.Conclusion:For the evaluation of fracture, hyperosteogeny, and bone destruction of knee joint and ankle joint, MRI FRACTURE sequence is highly consistent with CT.
ABSTRACT
Osteoporosis， as a systemic bone disease with high incidence rate and high disability rate， has become a research hotspot in recent years. The daidzein in soybean isoflavones can bind with estrogen receptors， simulating the prevention and treatment of osteoporosis with estrogen-like effect. Its mechanism of action includes promoting osteoblast formation and differentiation by activating the Wnt signaling pathway， increasing bone density， and improving bone tissue health； inhibiting osteoclast differentiation and slowing down bone resorption by reducing receptor activator of nuclear factors κB ligand/ osteoprotegerin ratio， downregulating the expression of macrophage colony-stimulating factor （M-CSF）； collaborating antioxidant and immune regulation to achieve the goal of preventing and treating osteoporosis. In addition， different doses of daidzein have different effects on bone density and osteoporosis， which may be related to factors such as study design， sample selection， and individual differences.
ABSTRACT
Objective To analyze the epidemiological characteristics of school varicella and varicella public health emergency event (PHEE) in Yunnan Province, and to provide a scientific basis for the prevention and control of varicella in schools. Methods The descriptive epidemiological method was used to analyze the reported PHEE of varicella in students and varicella in schools in Yunnan Province from 2018 to 2020. Results From 2018 to 2020, a total of 69,391 cases of varicella were reported in students in Yunnan Province, accounting for 71.48% (69 391 / 97 080) of the total cases in the province, and the annual average reported incidence rate was 255.56/100 000 (69 391/27.1522 million). The time distribution of the incidence showed double peaks, which were from May to July (26.48%) and October to January of the following year (53.88%). The incidence rates of different schools from high to low were 301.74/100 000 for primary schools (34 816/11.538 3 million), 250.43/100 000 for kindergarten (11 526/4.6024 million), 202.74/100 000 for middle school (16 779/8.276 1 million), and 119.07/100 000 for others (3 257/2.735 4 million). The age distribution was mainly concentrated in 5-9 years old, accounting for 39.81% (27 625/69 391). Varicella PHEE accounted for 25.64% (180/702）of the province's PHEE in the same period, school varicella PHEE accounted for 100% of varicella PHEE, and the attack rate was 3.38% (6 566/194 260). The sources of reported varicella PHEE were hospitals 45.40% (58/123), epidemic analysis 36.78% (44/123), schools 13.22% (15/123), and others 4.60% (6/123). Conclusion The incidence of varicella in schools in Yunnan Province is high, which is harmful to students. PHEE reported in rural schools are relatively lagging behind. On the basis of doing two doses of varicella vaccination, emergency prevention should be focused on epidemic seasons, lower grade schools and rural schools. The source of infection shall be controlled and managed in time to prevent the outbreak of the epidemic. It is recommended that varicella should be included in the management of Class C infectious diseases.

ABSTRACT
The concept of "ntigen"is a relative one. The narrow concept of it condenses the process of activation of adaptive immune response and re-recognition of the same antigen, revealing the protective mechanism of vaccines with great significance for research and development of vaccines. However, the narrow concept involves adaptive immune system members: B cells, T cells and their effector products, which is difficult for beginners to understand the inherent meaning. Meanwhile, antigen classification fully summarizes the immune response process, so a variety of classification approach increases the difficulty in learning. Our teaching team analyzes the difficulties of this chapter in depth, and we implements the strategy that takes antibody structure and function as the breakthrough point and simplified adaptive immune response process as the core in teaching. A mind map that includes the main contents of this chapter is made during the process, which promotes the effectiveness of classroom teaching greatly.

ABSTRACT
Objective:To investigate the clinical characteristics, treatments and prognosis of pulmonary arteriovenous fistula (PAVF) related ischemic stroke, as well as summarize the diagnosis and treatment process to screen and confirm PAVF related ischemic stroke.Methods:The clinical data of six PAVF related ischemic stroke patients in the First Affiliated Hospital of Fujian Medical University from January 2015 to January 2019, including clinical manifestations, brain magnetic resonance imaging, risk of paradoxical embolism (RoPE) score, contrast-enhanced transcranial Doppler (cTCD), contrast transesophageal echocardiography (cTEE), chest CT and pulmonary arteriography, were analyzed. PAVF patients were treated with interventional catheter embolization or conservative medication. All patients were followed up for 1.5 to 5.5 years.Results:All the six PAVF related ischemic stroke patients were young and middle-aged. The ratio of men to women was 1∶2. RoPE scores ranged from 6 to 7 points. Recurrent stroke was seen in five patients, and only one patient had primary stroke. Both anterior and posterior cerebral circulation could be involved. Hereditary hemorrhagic telangiectasia (HHT) was common in PAVF patients. Of the six patients, two had definite HHT with PAVF, two had suspicious HHT with PAVF, and the other two had sporadic PAVF. In all the six cases, a grade Ⅳright-to-left shunt (RLS) was observed on cTCD, and a mass of delayed microbubbles in the left atrium appeared on cTEE. One patient was diagnosed with patent foramen ovale (PFO). Lung enhanced CT was applied in all the patients. In three cases, PAVF was found located in left lower lobe. And in other three cases, lesions were located in left upper lobe, right lower lobe and right middle lung, separately. All cases were confirmed with simple type PAVF. Transcatheter embolization was performed to resolve PAVF in five patients. Of five post-operative patients, four cases showed no sign of RLS on cTCD. One patient combined with PFO still remained a small amount of potential RLS after embolization. One patient chose aspirin for conservative medication. All patients had no recurrence of ischemic stroke during the 1.5 to 5.5-year follow-up.Conclusions:PAVF related ischemic stroke patients have a high recurrence rate of ischemic stroke. PAVF related ischemic stroke has no specific brain imaging characteristics. cTCD is recommended for cryptogenic stroke patients with a high RoPE score (≥ 6 points) to detect RLS. If a patient turns out to be positive for RLS, cTEE could help differentiate intracardiac shunt from extracardiac shunt. For patients with cTEE suggesting extracardiac shunt, lung enhanced CT scan is necessary to confirm PAVF diagnosis. Patients who are diagnosed as PAVF can choose transcatheter embolization or surgical resection. cTCD could be used to evaluate the treatment effect.
ABSTRACT
Objective:To compare the effect of age on clinical outcome of laparoscopic sleeve gastrectomy (LSG) in the obese patients.Methods:A total of 113 patients who underwent LSG due to obesity and metabolic disorders between 2013 and 2018 at Fudan University Pudong Hospital, and completed the scheduled follow-up (1, 3, 6, and 12 months after surgery) were included for the retrospective analysis. The patients were divided into three groups based upon pre-operative age, including 15 to 30 year-old group ( n=58), 31 to 45 year-old group ( n=32), and 45 to 65 year-old group ( n=23). The body weight related parameters, glycemic and metabolic related parameters, lipid panel as well as arterial blood pressure were compared at pre-operative baseline, 1, 3, 6, and 12 months after surgery. The quantitative data were analyzed by repeated measurement ANOVA, and the P value was corrected by Bonferroni method. And the categorical variables were analyzed by chi square test. Results:The preoperative baseline data showed that with the increase of age, the preoperative body mass index gradually decreased, which were (40.1±5.9) kg/m 2, (37.1±6.6) kg/m 2 and (35.3±7.4) kg/m 2 in 16 to 30, 31 to 45 and 46 to 65 year-old groups, respectively. Otherwise, other metabolic related parameters were comparable. At 12 months after LSG, there was no significant difference in the amount of weight loss among the groups, but the percentage of total weight loss (% TWL) and the percentage of total BMI loss (%TBMIL) decreased significantly with age increasing. The %TBMIL in 16 to 30, 31 to 45 and 46 to 65 year-old groups were 32.3±7.5%, 28.4±8.4% ( P<005 compared with 16 to 30 year-old group) and 25.7±8.2% (compared with 16 to 30 year-old group P<0.001), respectively. In the patients with preoperative HbA1c>7%, HbA1c reduction in the three groups at 12 months after operation were 3.20% (compared with 46-65 year-old group P<0.001), 2.64% (compared with 46-65 year-old group P<0.05) and 1.34%, respectively. The proportions of patients with HbA1c < 6.5% were 95.8%, 88.9% and 50.0%, respectively. LDL, triglyceride and arterial blood pressure in all groups decreased and HDL increased rapidly within 3 months after operation, but there was no significant difference among the three groups. Conclusions:The improvement of blood glucose metabolism and the remission rate of type 2 diabetes mellitus (T2DM) in the patients with older age were worse than those in the younger patients, and the T2DM in the younger patients tends to obtain better clinical remission after LSG; in terms of weight loss, with the increase of age, %TWL and %TBMIL also showed a decreasing trend; however, the improvement of blood lipid and blood pressure after LSG was not affected by the factor of age. This study implies that patients who meet the indications of metabolic and bariatric surgery should be suggested to receive surgical treatment early in order to achieve better clinical outcomes.

ABSTRACT
This article reports the clinical manifestations, auxiliary examination, diagnosis, treatment, and prognosis of a congenital granular cell epulis (CGCE) case. A baby girl was admitted to Children's Hospital of Zhejiang University School of Medicine seven hours after birth due to difficulty in oral feeding caused by an oral cavity tumor detected prenatally. A palatine surgical resection was performed under general anesthesia based on imaging and related examination findings after admission. The patient was diagnosed as CGCE according to the pathological findings and discharged. During the follow-up, a new tooth emerged from the tumor resection site two weeks after discharge. The affected tooth was extracted at the Department of Stomatology of the hospital four weeks after discharge. The patient has no recurrence at follow-up visits till four months after the operation.
ABSTRACT
Objective:To explore the clinical and genetic characteristics of a Chinese baby with perinatal hypophosphatasia (HPP) and his parents for better understanding of the disease.Methods:The clinical data of the patient with HPP was carefully collected. The laboratory and radiographic examination data were taken for this baby patient. Sequencing for all the twelve tissue-nonspecific alkaline phosphatase(ALPL) exons and the flanking exon-intron junctions were performed in the proband and his parents with their genomic DNA from peripheral blood.Results:The blood level of alkaline phosphatase was decreased in this patient while serum calcium level was increased. His bone revealed chondrodysplasia-like change. Compound heterozygous mutations were found in the proband, with c. 346G>A(p.A116T) in exon 5 and c. 1171C>T(p.R391C) in exon 10. His father and mother were without clinical manifestation while respectively carried c. 346G>A(p.A116T and c. 1171C>T(p.R391C) missense mutations, suggesting an autosomal recessive inheritance in this family.Conclusion:Perinatal HPP has a high mortality rate. Skeletal deformities, hypercalcemia, and low level of ALP are important in the differential diagnosis of perinatal HPP.

Equipment and materials management shall be strengthened ，and equipment maintenance and disinfection shall be done well to ensure normal use of equipment. According to the evidence-based method ，the emergency drug list should be established. According to the disinfection protection requirements ，the disinfection products should be reasonably selected and their quality and sufficient inventory should be ensured. The qualified in vitro diagnostic reagents should be purchased in time. The investigational products should be managed reasonably according to the relevant requirements of clinical trials ，to ensure the drug and material supply of medical team members. Emergency plans and standard operating procedures shall be formulated，the principle of sympathetic drug use shall be followed ，and the management of off-label drug use and early warning of drug and material shortage shall be done well. Reasonable storage space should be reserved to strengthen environmental monitoring and disinfection. We should strengthen the monitoring and reporting of daily data ，strengthen the quality monitoring ， and accept the independent audit of the third party. Above strategies are helpful to improve the ability of drug supply risk identification and response ability ，and cooperate with the medical team to timely rescue patients.
ABSTRACT
Objective:To describe the long-term outcomes of intensive care unit (ICU) survivors of mechanical ventilation, and investigate the views of survivors on ICU rehabilitation clinics.Methods:A single-center cross-sectional descriptive study was designed. ICU survivors of mechanical ventilation admitted to the First Affiliated Hospital of Guangzhou Medical University from January to December 2016 were enrolled. Data were collected from August 2017 to March 2018. The general information questionnaire, Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) and ICU rehabilitation clinics questionnaire were used to evaluate ICU survivors social-demographic factors, social and economic outcomes, clinical data, quality of life and the views on ICU rehabilitation clinics.Results:A total of 248 ICU survivors of mechanical ventilation were included in the study, 130 (52.4%) of them were followed up successfully. The mean time from ICU discharge to follow-up day was (19.64±3.20) months. The average age of the survivors was (60.09±15.42) years old, and 55.4% of them were over 60 years old. Among 130 ICU survivors, severe pneumonia was the dominant ICU admission diagnosis (23.1%), followed by surgical operations (cardiac surgery 16.9%, other surgical operations 20.8%), lung transplantation (13.1%), and acute exacerbation of chronic obstructive pulmonary disease (AECOPD, 12.3%), etc. The first APACHEⅡ score after ICU admission was 16.88±7.37, the mechanical ventilation time was (12.52±12.34) days, and the length of ICU stay was (16.71±15.11) days. In terms of social and economic outcomes, the proportion of having full-time or part-time jobs decreased from 32.3% (42/130) before ICU admission to 25.4% (33/130) by the date of follow-up, while the unemployed rate increased from 6.9% (9/130) to 18.5% (24/130). Only 45.1% (23/51) of the ICU survivors returned to the post before ICU admission. 36.2% (47/130) of the ICU survivors reported that they needed care from others, and 86.9% (113/130) reported that their treatment experiences in ICU had an impact on their lives. In terms of quality of life, physiological function dimension, which was 34.62±33.15, scored the lowest and suffered the most. The physical pain dimension and mental health dimension suffered the least, and the scores were 90.19±16.98 and 75.28±15.15, respectively. Furthermore, physical component summary (PCS) score was 61.12±17.09, and mental component summary (MCS) score was 65.97±21.85. In terms of the views of ICU rehabilitation clinics, 68.5% (89/130) of the subjects believed that the establishment of ICU rehabilitation clinics was very helpful or helpful.Conclusions:The long-term outcomes of ICU survivors of mechanical ventilation are not optimistic. Their quality of life is lower than that of general people. It is necessary to set up ICU rehabilitation clinics.

ABSTRACT
Objective To investigate the identification of staphylococcus aureus lineage ST59 using the combined detection of delta hemolysin allelic variant G10S(HldG10S) and beta hemolysin(β-toxin). Methods Perspective study.A total of 82 non-duplicate clinical staphylococcus aureus were collected from November 2017 to April 2018 in the department of Clinical laboratory, the Third Xiangya Hospital of Central South University, China.The strains were routinely identified by MALDI-TOF MS and the mass spectra were obtained. According to the m/z expression intensity of delta hemolysin(Hld), all strains were divided into three groups:HldG10S (3036±2.0)m/z, Hld (3006±2.0)m/z and ND [no (3036±2.0)m/z and no (3006±2.0)m/z]. The distribution of ST59 in the three groups was detected by MLST. Reverse synergic hemolysis test was used to determine theβ-toxin phenotype. And the sensitivity, specificity and accuracy of HldG10S,β-toxin and the combined detection of HldG10S and Hld to identify ST59 were compared. Results Among the 82 strains, 21 strains expressed HldG10S toxin, accounting for 25.6％. 39 strains expressed Hld toxin, accounting for 47.6％.22 strains did not express HldG10S and Hld toxin, accounting for 26.8％. In HldG10S group,16 strains were ST59, accounting for 76.19％(16/21).ST59 was not found in both Hld and ND groups. All 16 strains of ST59 in HldG10S group producedβ-toxin, while none of the 5 strains of non-ST59 producedβ-toxin. The specificity(100％) and accuracy(100％) of the combined detection was significantly higher than that of HldG10S andβ-toxin single detection of specificity(92.4％, 77.3％) and accuracy(80.5％, 81.7％) (χ2=19.472, P<0.001;χ2=17.792, P<0.001). Conclusion The combined detection of HldG10S andβ-toxin can preliminarily and rapidly identify ST59, which can assist the routine monitoring of the change trend of staphylococcus aureus epidemic.
