Application of pulmonary circulation single-blocking method in intersegmental plane identification during segmentectomy / 中国胸心血管外科临床杂志

@#Objective    To introduce a new method for identifying intersegmental planes during thoracoscopic segmentectomy using pulmonary circulation single-blocking in the target segment. Methods    To retrospectively analyze the clinical data of 83 patients who underwent thoracoscopic pulmonary segmentectomy from January 2019 to March 2020 using the pulmonary circulation single-blocking method. There were 33 males and 50 females, with a median age of 54 (46-65) years, and they were divided into a single vein group (SVG, n=31) and a single artery group (SAG, n=52), and the clinical data of two groups were compared. Results    The intersegmental planes were identified successfully in both groups and there were no statistically significant differences between the two groups in terms of intersegmental plane management (P=0.823), operating time (P=0.786), intraoperative blood loss (P=0.775), chest drainage time (P=0.659), postoperative hospital stay (P=0.824) or the incidence of postoperative complications (P=1.000). Conclusion    The use of pulmonary circulation single-blocking for intersegmental plane identification during thoracoscopic segmentectomy is safe and feasible, and the intersegmental plane can be satisfactorily identified by the single-blocking of arteries or veins.

The distribution of total IgE in patients with allergic and their correlation with allergens and peripheral blood eosinophils / 中国医师进修杂志

Objective:To investigate the distribution of the total IgE, and their relationship with allergens and peripheral blood eosinophils in patients with allergic.Methods:The cross-sectional study was used, and 1 417 patients with allergic in Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine were selected. The serum total IgE was detected by enzyme-linked immunosorbent assay (ELISA), and the total IgE>60 kU/L was increased. The blood routine was detected by automated hematology analyzer. Using inhalant allergens and food allergens specific IgE antibody detection kits, the serum or plasma allergen-specific IgE antibodies were detected by Oumeng imprinting in vitro semi quantitative method.Results:Among 1 417 patients with allergic, elevated total IgE was in 617 cases (43.54%), normal total IgE in 800 cases (56.46%); 749 cases (52.86%) were allergic, the most common inhalation allergen was dust mite (38.72%, 218/563), and the most common food allergen was peanut (24.01%, 109/454). The rate of normal total IgE, eosinophils and non allergic was 19.20% (272/1 417). The male proportion, ratio of eosinophils, eosinophils count, total index of inhaled allergens, total index of non inhaled allergens, number of positive allergens, total positive index and average positive index in patients with elevated total IgE were significantly higher than those in patient with normal total IgE, the age was significantly lower than that in patients with normal total IgE, and there were statistical differences ( P<0.01). The total IgE<60 kU/L (normal total IgE) was in 800 cases, total IgE from 60 to 499 kU/L (mild elevation of total IgE) in 487 cases, total IgE from 500 to 999 kU/L (moderate elevation of total IgE) in 78 cases, total IgE≥1 000 kU/L (severe elevation of total IgE) in 52 cases. The male proportion and age in patients with sever elevation of total IgE and moderate elevation of total IgE were significantly higher than those in patients with mild elevation of total IgE and normal total IgE, and there were statistical differences ( P<0.05). The compound allergy rate in patients with severe elevation of total IgE was significantly higher than that in patients with moderate elevation of total IgE, mild elevation of total IgE and normal total IgE: 73.08% (38/52) vs. 60.26% (47/78), 38.40% (187/487), 17.00% (136/800), and there was statistical difference ( P<0.05). The ratio of eosinophils, eosinophils count and number of positive allergens increased with increasing total IgE level, and there was statistical difference ( P<0.05). The number of dermatophagoides/dermatophagoides culinae allergic in patients with moderate elevation of total IgE was significantly more than that in patients with sever elevation of total IgE, mild elevation of total IgE and normal total IgE, and there was statistical difference ( P<0.05). Conclusions:Allergic disease may show a normal level of total IgE. Males are more likely to be troubled with high level of IgE. Patients with total IgE ≥1 000 kU/L should be alert to the possibility of poly-sensitization. Total IgE was no longer correlated with individual allergy severity in patients with total IgE≥500 kU/L.

Effects of extrafine-particle versus fine-particle inhaled corticosteroids combined with formoterol on large and small airway function in patients with bronchial asthma / 中国医师进修杂志

Objective:To compare the effects of extrafine-particle versus fine-particle inhaled corticosteroids (ICS) combined with formoterol on clinical symptoms, airway inflammation and airway function in patients with bronchial asthma (referred to as asthma).Methods:This prospective, randomized controlled clinical trial enrolled a total of 111 patients diagnose of asthma and cough variant asthma with forced expired volume in one second (FEV 1) percentage of predicted (FEV 1%pred) >70% in Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from November 2020 to October 2022. The patients were divided into observation group (57 cases) and control group (54 cases) by random digits table method. The patients in observation group were treated with extrafine-particle ICS combined with formoterol, while the patients in control group were treated with fine-particle ICS combined with formoterol. Both groups were treated for 4 weeks. During treatment 10 patients lost follow up and a total of 101 patients complete the final study: 52 cases in observation group and 49 cases in control group. At baseline, the asthma control test (ACT) score was calculated to evaluate the clinical symptoms, fractional exhaled nitric oxide (FeNO) was applied to evaluate the airway inflammatory level, and the pulmonary function test and bronchodilation test were perfromed. The symptom relief time was record. After treatment, all of the parameters were reevaluated. Results:The FEV 1, peak expiratory flow (PEF), forced expired flow at 50% of forced vital capacity (MEF 50), forced expired flow at 25% of forced vital capacity (MEF 25), maximal expiratory flow-volume curve (MMEF) and ACT score after treatment in both groups were significantly improved compared to baseline, and there were statistical differences ( P<0.01). The improvement of ACT score in observation group was significantly higher than that in control group: (5.90 ± 2.25) scores vs. (4.10 ± 2.18) scores, and there was statistical difference ( P<0.01); there were no statistical differences in the symptom relief time and the improvement rates of FEV 1, PEF, MEF 50, MEF 25, MMEF between the two groups ( P>0.05). Further subgroup analysis was performed on 78 patients with small airway dysfunction, 39 patients were treated with extrafine-particle ICS combined with formoterol (observation subgroup), and 39 patients were treated with fine-particle ICS combined with formoterol (control subgroup). The improvement of ACT score in observation subgroup was significantly higher than that in control subgroup: (6.05 ± 2.22) scores vs. (3.95 ± 2.19) scores, and there was statistical difference ( P<0.01); there were no statistical differences in the symptom relief time and the improvement rates of FEV 1, PEF, MEF 50, MEF 25, MMEF between the two subgroups ( P>0.05). Spearman correlation analysis result showed that the improvement rates of MEF 50, MEF 25 and MMEF after treatment were positive correlated with baseline bronchodilator responses of FEV 1, FEV 1/FVC, MEF 50, MEF 25, MMEF ( r = 0.22 to 0.58, P<0.05), but not with baseline bronchodilator responses of PEF ( P>0.05). In terms of safety, neither of the two treatments had major adverse reactions that affect treatment. Conclusions:For asthma patients with baseline FEV 1%pred>70%, the extrafine-particle ICS combined with formoterol has more significantly improved of clinical symptoms compared to fine-particle ICS combined with formoterol, and potentially with better safety profile. The improvement ratio of small airway function parameters in baseline bronchodilation test could potentially predict treatment response.

Effects of vitamin D diet early in life on airway inflammation in different endotypes of asthma mice models / 中国医师进修杂志

Objective:To investigate the effects of different doses of vitamin D diet early in life on airway inflammation in different endotypes of asthma mice models.Methods:In the Animal House of Shanghai General Hospital of Nanjing Medical University in June 2022, the BALB/c mice with 14 d pregnant were selected, the offspring mice were divided into vitamin D sufficient group and vitamin D deficient group by random number table method with 12 each. The mice in the vitamin D sufficient group were given a feed with sufficient vitamin D content, while the mice in the vitamin D deficient group were given a feed without vitamin D. At the age of 8 weeks, the mice were sensitized and stimulated with ovalbumin to establish a T2 type asthma model, while the mice were sensitized and stimulated with ovalbumin combined with ozone exposure to establish a non-T2 type asthma model, with 6 mice in each model. The level of serum 25 hydroxy vitamin D 3 was detected by enzyme-linked immunosorbent assay (ELISA) method. The lung tissue was stained with HE to evaluate the inflammatory response score and calculate the eosinophils density and neutrophils density. In bronchoalveolar lavage fluid (BALF), the expression levels of interleukin (IL)-4, IL-6, IL-10 and IL-17A, the inflammatory cell count (total cell count, neutrophil count and eosinophil count) were detected. Results:The 25 hydroxy vitamin D 3 in T2 type asthma mice and non-T2 type asthma mice of vitamin D deficient group were significantly lower than that in vitamin D sufficient group: (8.12 ± 1.72) μg/L vs. (26.63 ± 2.54) μg/L and (6.86 ± 1.65) μg/L vs. (23.81 ± 3.09) μg/L, and there was statistical difference ( P<0.01). The inflammatory response score in non-T2 type asthma mice of vitamin D deficient group was significantly higher than that in non-T2 type asthma mice of vitamin D sufficient group: (2.58 ± 0.49) scores vs. (1.83 ± 0.21) scores, and there was statistical difference ( P<0.05), there was no statistical differences in inflammatory response score in T2 type asthma mice between two groups ( P>0.05). The neutrophils density and eosinophils density in T2 type asthma mice and non-T2 type asthma mice of vitamin D deficient group were significantly higher than those in vitamin D sufficient group, T2 type asthma mice: (20.30 ± 1.95) cells/100 μm vs. (12.58 ± 1.04) cells/100 μm and (5.25 ± 0.62) cells/100 μm vs. (3.15 ± 0.35) cells/100 μm; non-T2 type asthma mice: (53.48±5.19) cells/100 μm vs. (33.80 ± 2.74) cells/100 μm and (3.00 ± 0.29) cells/100 μm vs. (2.17 ± 0.21) cells/100 μm, and there were statistical differences ( P<0.01 or <0.05). The BALF total cell count in T2 type asthma mice and non-T2 type asthma mice of vitamin D deficient group was significantly higher than that in vitamin D sufficient group, the BALF eosinophil count in T2 type asthma mice of vitamin D deficient group was significantly higher than that in T2 type asthma mice of vitamin D sufficient group, the BALF neutrophil count in non-T2 type asthma mice of vitamin D deficient group was significantly higher than that in T2 type asthma mice of vitamin D sufficient group, and there were statistical differences ( P<0.01); there was no statistical difference in BALF neutrophil count in T2 type asthma mice between two groups ( P>0.05); there was no statistical difference in BALF eosinophil count in non-T2 type asthma mice between two groups ( P>0.05). The BALF total cell count and neutrophil count in non-T2 type asthma mice of both groups were significantly higher than those in T2 type asthma mice, but the BALF eosinophil count in T2 type asthma mice was significantly higher non-T2 type asthma mice, and there were statistical differences ( P<0.05). The BALF IL-4, IL-6 and IL-17A in T2 type asthma mice and non-T2 type asthma mice of vitamin D deficient group were significantly higher than those in vitamin D sufficient group, the BALF IL-10 was significantly lower than those in vitamin D sufficient group, and there were statistical differences ( P<0.01 or <0.05). In vitamin D deficient group, the BALF IL-4 in non-T2 type asthma mice was significantly lower than that in T2 type asthma mice, the BALF IL-6 and IL-17A were significantly higher than those in T2 type asthma mice, and there were statistical differences ( P<0.05); in vitamin D sufficient group, the BALF IL-6 and IL-17A in non-T2 type asthma mice were significantly higher than those in T2 type asthma mice, and there were statistical differences ( P<0.05). Conclusions:Vitamin D deficiency is involved in different mechanisms of airway inflammation in T2 type asthma and non-T2 type asthma, and this effect may be more obvious for non-T2 type asthma.

Correlation study between early neurological deterioration and cerebral microbleeds in patients with acute small artery occlusion / 中国医师进修杂志

Objective:To investigate the relationship between the degree and location of cerebral microbleeds (CMBs) and the early neurological deterioration (END) within 72 h after admissionin in patients with acute small artery occlusive stroke (SAO).Methods:Patients with first-onset SAO hospitalized in Changzhou Second People′s Hospital from July 2020 to January 2021 were retrospectively enrolled. All patients completed the head magnetic resonance imaging including susceptibility weighted imaging. Collected baseline data, and evaluated the National Institutes of Health Stroke Scale (NHISS) scores before admission and within 72 h after onset. Patients were divided into END group and no END group according to whether NIHSS scores increased by ≥3 within 72 h after admission. The baseline characteristics were compared between these two groups. Moreover, the correlation between the degree and location of CMBs and END were analyzed by multivariate Logistic regression.Results:A total of 163 first-episode SAO patients were enrolled. There were 47 patients (28.83%) with END. In END group, there were 35 patients (74.47%) with CMBs which was higher than those in non-END group [42 patients (36.21%)]. In END group, there were 21 patients (44.68%) with severe CMBs, 11 patients (23.41%) with basal ganglia CMBs, 16 patients (34.04%) with mixed CMBs, which were all higher than those in non-END group [5 patients (4.31%) with severe CMBs, 9 patients (7.76%) with basal ganglia CMBs, and 13 patients (11.21%) with mixed CMBs]. The difference was statistically significant ( P<0.05). After adjusting for triglyceride, location of infarcated lesions, and the degree of WMHs, further Logistic regression analysis revealed that severe CMBs ( OR = 6.139, 95% CI 1.377 - 27.375, P = 0.017), basal ganglia CMBs ( OR = 5.253, 95% CI 1.105 - 24.975, P = 0.037) and mixed CMBS ( OR = 5.098, 95% CI 1.197 - 21.704, P = 0.028) were independent risk factors of END in SAO patients. Conclusions:The location and degree of CMBs are closely related to the occurrence of END in patients with SAO. Severe CMBs, basal ganglia CMBs and mixed CMBs may be the effective predictors of END in patients with SAO.

Clinical characteristics of neonatal gastric perforation and risk factors of mortality / 中国新生儿科杂志

Objective:To study the clinical characteristics of neonatal gastric perforation (NGP) and risk factors of mortality.Methods:From January 2015 to May 2022, infants with NGP admitted to NICU of our hospital were retrospectively studied. They were assigned into the survival group and the death group. Clinical manifestations, laboratory and imaging results, surgical treatments and prognosis were compared and risk factors of mortality were determined.Results:A total of 27 infants with NGP were enrolled, including 17 males and 10 females. 24 were premature infants and 3 were term infants. 26 infants had low birth weight. 3 infants had neonatal resuscitation due to asphyxia, 10 received positive pressure ventilation before the onset of perforation symptoms, 2 showed gastrointestinal malformations and 3 with septic shock before surgery. The median age of onset was 2.0 d. The main presenting symptom was abdominal distension, with most perforations occurring at the greater curvature of the stomach. 20 cases had congenital gastric muscular layer defects. 21 cases survived and 6 cases died. Age of onset was later in the death group than the survival group [2.5 (2.0, 7.8) days vs. 1.9 (1.4, 3.0) days]. The survival group had higher preoperative platelet count than the death group [(218±80) ×10 9/L vs. (126±73)×10 9/L]. The incidences of thrombocytopenia, septic shock and multi-organ dysfunction syndrome before surgery in the survival group were significantly lower than the death group ( P<0.05). Logistic regression analysis showed that preoperative thrombocytopenia was a risk factor for NGP mortality ( OR=19.000, 95% CI 2.029-177.932, P=0.010). Conclusions:NGP is more common in male infants, premature infants and low birth weight infants. The most common etiology is congenital gastric muscular layer defects. The mortality rate is high and preoperative thrombocytopenia is a risk factor for mortality.

Patients with CSVD may be accompanied by cardiovascular, endocrine, gastrointestinal, urination, sleep disorders and other autonomic dysfunction.

Application strategy of the Principles and Guidelines for Human Factors/Ergonomics (HFE) Design and Management of Work Systems in China / 中国职业医学

To provide in-depth information and guidance on ergonomics, the International Labour Organization (ILO) had issued a series of conventions, recommendations, and resolutions on human factors/ergonomics (HFE) and had published HFE guides and toolkits. In 2021, the ILO and the International Ergonomics Association released an international guideline on HFE entitled Principles and Guidelines for Human Factors/Ergonomics (HFE) Design and Management of Work Systems (hereinafter referred to as the HEF Guidelines), aiming to improve the occupational safety, health, and the well-being of workers from the perspective of work system sustainability. There are currently 112 national health standards in China related to HFE, of which 79 (accounting for 71%) are equivalent to relevant standards from the International Organization for Standardization. Most of the recommended standards do not meet the applicability requirements of HFE for the Chinese workforce, as they are different from the national occupational health standard system. At present, China's HFE capability cannot meet the needs of the workforce, and there is still a gap between occupational diseases related to HFE included in the Occupational Disease List of China and those compared to the ILO. In the future, China needs to pay attention to the application of the HEF Guidelines, further improve the technical services for occupational health, include diseases caused by poor ergonomics in the national occupational disease list, strengthen the HFE standard system in the national occupational health standard system, actively promote the application of action-oriented HFE tools, enhance “human-machine coordination” and “person-job matching”, and focus on physical and cognitive HFE design to promote equality in workplace and reduce the occurrence of occupational and work-related diseases.

HSDL2 overexpression promotes rectal cancer progression by regulating cancer cell cycle and promoting cell proliferation / 南方医科大学学报

OBJECTIVE@#To analyze the expression of hydroxysteroid dehydrogenase like 2 (HSDL2) in rectal cancer tissues and the effect of changes in HSDL2 expression level on proliferation of rectal cancer cells.@*METHODS@#Clinical data and tissue samples of 90 patients with rectal cancer admitted to our hospital from January 2020 to June 2022 were collected from the prospective clinical database and biological specimen database. The expression level of HSDL2 in rectal cancer and adjacent tissues was detected by immunohistochemistry, and based on the median level of HSDL2 expression, the patients were divided into high expression group (n=45) and low expression group (n=45) for analysis the correlation between HSDL2 expression level and the clinicopathological parameters. GO and KEGG enrichment analyses were performed to explore the role of HSDL2 in rectal cancer progression. The effects of changes in HSDL2 expression levels on rectal cancer cell proliferation, cell cycle and protein expressions were investigated in SW480 cells with lentivirus-mediated HSDL2 silencing or HSDL2 overexpression using CCK-8 assay, flow cytometry and Western blotting.@*RESULTS@#The expressions of HSDL2 and Ki67 were significantly higher in rectal cancer tissues than in the adjacent tissues (P < 0.05). Spearman correlation analysis showed that the expression of HSDL2 protein was positively correlated with Ki67, CEA and CA19-9 expressions (P < 0.01). The rectal cancer patients with high HSDL2 expressions had significantly higher likelihood of having CEA ≥5 μg/L, CA19-9 ≥37 kU/L, T3-4 stage, and N2-3 stage than those with a low HSDL2 expression (P < 0.05). GO and KEGG analysis showed that HSDL2 was mainly enriched in DNA replication and cell cycle. In SW480 cells, HSDL2 overexpression significantly promoted cell proliferation, increased cell percentage in S phase, and enhanced the expression levels of CDK6 and cyclinD1 (P < 0.05), and HSDL2 silencing produced the opposite effects (P < 0.05).@*CONCLUSION@#The high expression of HSDL2 in rectal cancer participates in malignant progression of the tumor by promoting the proliferation and cell cycle progress of the cancer cells.

Analysis of the clinical characteristics and misdiagnosis of area postrema syndrome manifesting as intractable nausea, vomiting, and hiccups in neuromyelitis optica spectrum disorders / 中华内科杂志

Objective: To investigate the misdiagnosis of area postrema syndrome (APS) manifesting as intractable nausea, vomiting and hiccups in neuromyelitis optic spectrum disease (NMOSD) and reduce the risk of misdiagnosis. Methods: We retrospectively analyzed data from NMOSD patients attending the Department of Neurology at the First Medical Center of PLA General Hospital between January 2019 and July 2021. SPSS25.0 was then used to analyze the manifestations, misdiagnosis, and mistreatment of APS. Results: A total of 207 patients with NMOSD were included, including 21 males and 186 females. The mean age of onset was 39±15 years (range: 5-72 years). The proportion of patients who were positive for serum aquaporin 4 antibody was 82.6% (171/207). In total, 35.7% (74/207) of the NMOSD patients experienced APS during the disease course; of these patients, 70.3% (52/74) had APS as the first symptom and 29.7% (22/74) had APS as a secondary symptom. The misdiagnosis rates for these conditions were 90.4% (47/52) and 50.0% (11/22), respectively. As the first symptom, 19.2% (10/52) of patients during APS presented only with intractable nausea, vomiting and hiccups; 80.8% (42/52) of patients experienced other neurological symptoms. The Departments of Gastroenterology and General Medicine were the departments that most frequently made the first diagnosis of APS, accounting for 54.1% and 17.6% of patients, respectively. The most common misdiagnoses related to diseases of the digestive system and the median duration of misdiagnosis was 37 days. Conclusions: APS is a common symptom of NMOSD and is associated with a high rate of misdiagnosis. Other concomitant symptoms often occur with APS. Gaining an increased awareness of this disease/syndrome, obtaining a detailed patient history, and performing physical examinations are essential if we are to reduce and avoid misdiagnosis.

Expert consensus on late stage of critical care management / 中华内科杂志

We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

Short-term efficacy of empagliflozin in children with glycogen storage disease type Ⅰb / 中华儿科杂志

Objective: To analyze the short-time efficacy of empagliflozin in the treatment of glycogen storage disease type Ⅰb (GSD Ⅰb). Methods: In this prospective open-label single-arm study, the data of 4 patients were collected from the pediatric department in Peking Union Medical College Hospital from December 2020 to December 2022. All of them were diagnosed by gene sequencing and had neutropenia. These patients received empagliflozin treatment. Their clinical symptoms such as height and weight increase, abdominal pain, diarrhea, oral ulcer, infection times, and drug applications were recorded at 2 weeks, 1 month, 2 months, 3 months, 6 months, 9 months, 12 months, and 15 months after treatment to assess the therapeutic effect. The liquid chromatography-tandem mass spectrometry method was used to monitor the changes in 1, 5-anhydroglucitol (1, 5AG) concentration in plasma. At the same time, adverse reactions such as hypoglycemia and urinary tract infection were closely followed up and monitored. Results: The 4 patients with GSD Ⅰb were 15, 14, 4 and 14 years old, respectively at the beginning of empagliflozin treatment, and were followed up for 15, 15, 12 and 6 months, respectively. Maintenance dose range of empagliflozin was 0.24-0.39 mg/(kg·d). The frequency of diarrhea and abdominal pain decreased in cases 2, 3, and 4 at 1, 2 and 3 months of treatment, respectively. Their height and weight increased at different degrees.The absolute count of neutrophils increased from 0.84×109, 0.50×109, 0.48×109, 0.48×109/L to 1.48×109, 3.04×109, 1.10×109, 0.73×109/L, respectively. Granulocyte colony-stimulating factor was gradually reduced in 1 patients and stopped in 3 patient. Plasma 1, 5 AG levels in 2 children were significantly decreased after administration of empagliflozin (from 46.3 mg/L to 9.6 mg/L in case 2, and from 56.1 mg/L to 15.0 mg/L in case 3). All 4 patients had no adverse reactions such as hypoglycemia, abnormal liver or kidney function, or urinary system infection. Conclusion: In short-term observation, empagliflozin can improve the symptoms of GSD Ⅰb oral ulcers, abdominal pain, diarrhea, and recurrent infection, also can alleviate neutropenia and decrease 1, 5AG concentration in plasma, with favorable safety.

Immunogenicity and safety of revaccination of 23-valent pneumococcal polysaccharide vaccine in people aged 60 years and above / 中华流行病学杂志

Objective: To evaluate the immunogenicity and safety of revaccination of 23-valent pneumococcal polysaccharide vaccine (PPV23) in elderly people aged ≥60 years. Methods: The elderly aged ≥60 years with 1 dose of PPV23 vaccination were selected as revaccination group and those without history of pneumococcal vaccine immunization were selected as the first vaccination group. One dose of PPV23 was administered to both groups, and the first blood samples were collected before vaccination while the second blood samples were collected on day 28-40 after vaccination. ELISA was used to detect the concentrations of anti-specific serotype Streptococcus pneumoniae podocyte polysaccharide immunoglobulin G, and the safety of the vaccination was evaluated after 30 days. Results: The geometric mean concentration (GMC) of antibody to 23 serotypes before the vaccination (0.73-13.73 μg/ml) was higher in revaccination group than in the first vaccination group (0.39-7.53 μg/ml), the GMC after the vaccination (1.42-31.65 μg/ml) was higher than that before the vaccination (0.73-13.73 μg/ml) in the revaccination group, and the GMC after the vaccination (1.62-43.76 μg/ml) was higher than that before the vaccination (0.39-7.53 μg/ml) in the first vaccination group; the geometric mean growth multiple in revaccination group (2.16-3.60) was lower than that in the first vaccination group (3.86-16.13); The mean 2-fold antibody growth rate was lower in revaccination group (53.68%, 95%CI: 52.30%-55.06%) than in the first vaccination group (93.16%, 95%CI: 92.18%- 94.15%), all differences were significant (P<0.001). After the vaccination, 13 serotypes of GMC were higher in the first vaccination group than in revaccination group (P<0.001), the differences were not significant for 10 serotypes of GMC (P>0.05). The incidence of local adverse reaction was 19.20% and 13.27% in revaccination group and the first vaccination group, respectively (P=0.174). Conclusions: The antibody level in ≥60 years people who received one dose of PPV23 after a 5-year interval was still higher than that in unvaccinated people. The antibody level decreased after 5 years of the first vaccination, and the antibody level could be rapidly increased by one more dose vaccination, but the overall immune response was lower than that of the first vaccination; revaccination with PPV23 has a good safety.

Analysis and prediction of thyroid cancer morbidity and mortality trends in China / 中华流行病学杂志

Objective: To analyze the morbidity and mortality trends of thyroid cancer in China from 1990 to 2019, explore the causes of the trends, and predict morbidity and mortality in the future. Methods: The morbidity and mortality data of thyroid cancer in China from 1990 to 2019 were collected from the 2019 Global Burden of Disease database. The Joinpoint regression model was used to describe the change trends. Based on the morbidity and mortality data from 2012 to 2019, a grey model GM (1,1) was constructed to predict the trends in the next ten years. The model was tested by the posterior error method and residual test method. Results: In all populations, men and women, the AAPC values of the crude morbidity rates were 4.15% (95%CI: 3.86%-4.44%, P<0.001), 5.98% (95%CI: 5.65%-6.31%, P<0.001) and 3.23% (95%CI: 2.94%-3.53%, P<0.001) respectively, the AAPC values of age-standardized morbidity rates were 2.47% (95%CI: 2.12%-2.83%, P<0.001), 3.98% (95%CI: 3.68%-4.29%, P<0.001), 1.65% (95%CI: 1.38%-1.93%, P<0.001), the AAPC values of crude mortality rates were 2.09% (95%CI: 1.92%-2.25%, P<0.001), 3.68% (95%CI: 3.45%-3.90%, P<0.001), 0.60% (95%CI: 0.50%-0.71%, P<0.001). The age-standardized mortality rates in men showed a fluctuating trend of first decrease (1990-1994), then increase (1994-2012), and then decrease (2012-2019) (AAPC=1.35%, 95%CI: 1.16%-1.53%, P<0.001). The age-standardized mortality rate in women continuously decreased (AAPC=-1.70%, 95%CI: -1.82%- -1.58%, P<0.001). The GM (1,1) models can be used for medium and long-term predictions. The results of the residual test show that the average relative error values of all models are less than 10.00%, the prediction accuracy values are more than 80.00%, and the prediction effects are good. The results of the posterior error method show that all the prediction results are good except the qualified prediction of the age-standardized morbidity rate in men. In 2029, the crude morbidity rates would increase to 3.57/100 000, 2.78/100 000, and 4.40/100 000, respectively, and the age-standardized incidence rates would increase to 2.38/100 000, 1.89/100 000, and 2.88/100 000, respectively, the crude mortality rates would increase to 0.57/100 000, 0.62/100 000 and 0.53/100 000, and the age-standardized mortality rates would decrease to 0.33/100 000, 0.42/100 000 and 0.27/100 000 in all population, men and women in China. Conclusions: The overall, gender- specific age-standardized mortality rates showed downward trends in the last decade or so, and the prediction results showed that it might further decline. However, the crude morbidity rates, age-standardized and crude mortality rates have been on the rise, and the population aging is becoming increasingly serious in China, which requires close attention and targeted prevention and control measures.

Epidemiological distribution of genotypes and sub-genotypes of hepatitis B virus in 15 ethnic groups in China / 中华流行病学杂志

Objective: To understand the distribution of genotypes and sub-genotypes of HBV in different ethnic groups in China. Methods: The HBsAg positive samples were selected by stratified multi-stage cluster sampling from the sample base of national HBV sero-epidemiological survey in 2020 for the amplification of S gene of HBV by nested PCR. A phylogeny tree was constructed to determine the genotypes and sub-genotypes of HBV. The distribution of genotypes and sub-genotypes of HBV were analyzed comprehensively by using laboratory data and demographic data. Results: A total of 1 539 positive samples from 15 ethnic groups were successfully amplified and analyzed, and 5 genotypes (B, C, D, I and C/D) were detected. The proportion of genotype B was higher in ethnic group of Han (74.52%, 623/836), Zhuang (49.28%, 34/69), Yi (53.19%, 25/47), Miao (94.12%, 32/34), Buyi (81.48%, 22/27). The proportions of genotype C were higher in ethnic groups of Yao (70.91%, 39/55). Genotype D was the predominant genotype in Uygur (83.78%, 31/37). Genotype C/D were detected in Tibetan (92.35%,326/353). In this study, 11 cases of genotype I were detected, 8 of which were distributed in Zhuang nationality. Except for Tibetan, sub-genotype B2 accounted for more than 80.00% in genotype B in all ethnic groups. The proportions of sub-genotype C2 were higher in 8 ethnic groups, i.e. Han, Tibetan, Yi, Uygur, Mongolian, Manchu, Hui and Miao. The proportions of sub-genotype C5 were higher in ethnic groups of Zhuang (55.56%, 15/27) and Yao (84.62%, 33/39). For genotype D, sub-genotype D3 was detected in Yi ethnic group and sub-genotype D1 was detected in both Uygur and Kazak. The proportions of sub-genotype C/D1 and C/D2 in Tibetan were 43.06% (152/353) and 49.29% (174/353). For all the 11 cases of genotype I infection, only sub-genotype I1 was detected. Conclusions: Five genotypes and 15 sub-genotypes of HBV were found in 15 ethnic groups. There were significant differences in the distribution of genotypes and sub-genotypes of HBV among different ethnic groups.

Research progress on neurodevelopmental outcomes of small for gestational age infants / 中华预防医学杂志

The incidence of perinatal disease and perinatal mortality in small for gestational age infants increased significantly. This group of people is prone to a variety of long-term metabolic diseases and cardiovascular diseases, and is also prone to growth retardation and neurodevelopmental delay, which will seriously affect the long-term quality of life of children. The article studies the neurodevelopmental outcomes of small-for-gestational-age infants. By reviewing and sorting out previous literature, the neurodevelopmental disorders of small-for-gestational-age infants are analyzed according to five aspects: intellectual development, motor development, language development, sensory development, and mental illness. The classification and summary were carried out, and the influencing factors of neurodevelopmental disorders of SGA were also evaluated, so as to provide reference for promoting the improvement of neurodevelopmental outcomes of small-for-gestational-age infants.

Associations of mobile phone use with male semen quality and sex hormones / 环境与职业医学

Background Experimental studies have shown that radiofrequency electromagnetic waves emitted by mobile phones can cause adverse effects on male reproductive health, including decreased semen quality and altered sex hormones. However, the results of epidemiological studies on the relationship between mobile phone use and male semen quality are inconsistent. Furthermore, there are few epidemiological studies on the association of mobile phone use with sex hormones. Objective To explore the associations of mobile phone use with male semen quality and sex hormones. Methods A total of 2045 men visited the reproductive medicine center of a hospital in Wuhan and ordered infertility examination were recruited from December 2018 to January 2020. Information on mobile phone use was obtained using a questionnaire. Among them, 1232 and 1694 men were eligible for semen quality analyses and sex hormone analyses, respectively. Multiple linear and logistic regression models were used to analyze the associations of mobile phone use with male semen quality and sex hormones. Results After adjusting for potential confounders, there was no statistically significant associations of mobile phone use with sperm progressive motility, sperm total motility, sperm concentration, sperm count, or serum luteinizing hormone (P>0.05). However, serum total testosterone showed a declined tendency with increasing daily duration of mobile phone use (Ptrend=0.08). Compared with men with daily mobile phone use of 0-2 h, men with daily mobile phone use of 2.1-5, 5.1-8, and >8 h showed decreased serum total testosterone concentrations by 6.29% (95%CI: 0.40%-11.84%), 6.01% (95%CI: 0.60%-12.19%), and 7.87% (95%CI: 0.40%-14.79%), respectively. Conclusion Mobile phone use is not associated with male semen quality and serum luteinizing hormone, but increasing daily duration of mobile phone use is potentially associated with a tendency to lower male serum total testosterone.

A consensus on the management of allergy in kindergartens and primary schools / 中国学校卫生

Abstract@#Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.
