Based on transcriptome sequencing technology, the mouse model of prediabetes treated with Huangjing Qianshi Decoction was sequenced to explore the possible mechanism of treating prediabetes. First of all, transcriptome sequencing was performed on the normal BKS-DB mouse group, the prediabetic model group, and the Huangjing Qianshi Decoction treatment group(treatment group) to obtain differentially expressed genes in the skeletal muscle samples of mice. The serum biochemical indexes were detected in each group to screen out the core genes of Huangjing Qianshi Decoction in prediabetes. Gene Ontology(GO) database and Kyoto Encyclopedia of Genes and Genomes(KEGG) database were used to conduct signaling pathway enrichment analysis of differentially expressed genes, and real-time quantitative polymerase chain reaction(RT-qPCR) was used to verify them. The results showed that the levels of fasting blood glucose(FBG), fasting insulin(FINS), insulin resistance index(HOMA-IR), total cholesterol(TC), triglycerides(TG), and low-density lipoprotein cholesterol(LDL-C) in the mouse model were significantly decreased after treatment with Huangjing Qianshi Decoction. In the results of differential gene screening, there were 1 666 differentially expressed genes in the model group as compared with the normal group, and there were 971 differentially expressed genes in the treatment group as compared with the model group. Among them, interleukin-6(IL-6) and NR3C2 genes, which were closely related to the regulation of insulin resis-tance function, were significantly up-regulated between the model group and the normal group, and vascular endothelial growth factor A(VEGFA) genes were significantly down-regulated between the model group and the normal group. However, the expression results of IL-6, NR3C2, and VEGFA genes were adverse between the treatment group and the model group. GO functional enrichment analysis found that the biological process annotation mainly focused on cell synthesis, cycle, and metabolism; cell component annotation mainly focused on organelles and internal components; and molecular function annotation mainly focused on binding molecular functions. KEGG pathway enrichment analysis found that it involved the protein tyrosine kinase 6(PTK6) pathway, CD28-dependent phosphoinositide 3-kinase/protein kinase B(PI3K/AKT) pathway, p53 pathway, etc. Therefore, Huangjing Qianshi Decoction can improve the state of prediabetes, and the mechanism may be related to cell cycle and apoptosis, PI3K/AKT pathway, p53 pathway, and other biological pathways regulated by IL-6, NR3C2, and VEGFA.

Objective: To investigate the current status of humanistic care ability of burn specialist nurses and to analyze the influencing factors. Methods: A single-center cross-sectional research method was conducted. From May to August 2020, 63 burn specialist nurses who met the inclusion criteria in Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine were selected. Self-made general data questionnaire was used to investigate 17 indexes, including gender, age, professional title, working years, whether received humanistic care training, academic qualification, and caring ability inventory (CAI) was used to evaluate their humanistic care ability. After the nurses were classified by the general data, independent sample t test and one-way analysis of variance were performed on the data to analyze the total score of CAI. The CAI total scores and scores of cognition, courage, and patience of the nurses were compared with the international norm. The factors with statistically significant differences in unvariate analysis were selected for multiple linear regression analysis to screen the independent influencing factors of humanistic care ability of burn specialist nurses. Results: A total of 63 questionnaires were collected in this survey, all of which were valid. Among the 63 nurses, there were 4 males and 59 females, with the age mainly ranging from 20 to 30 years (30 nurses, 47.62%), the professional titles mainly being nurse practitioner (36 nurses, 57.14%), the working years mainly being more than 10 years (28 nurses, 44.44%), 32 nurses not receiving humanistic care training, and academic qualifications mostly being junior college (37 nurses, 58.73%). There were significant differences in the total scores of CAI among nurses with different ages, professional titles, working years, whether received humanistic care training, and academic qualifications (with F values of 53.95, 49.14, and 75.42, t values of 6.08 and -2.82, respectively, P<0.01). The scores of cognition, courage, and patience and the total scores of CAI of nurses in this group were significantly lower than those of international norm (with t values of -2.02, -2.04, -6.19, and -3.89, respectively, P<0.05 or P<0.01). Multiple linear regression analysis showed that age, working years, professional title, and whether received humanistic care training were the independent influencing factors of humanistic care ability of burn specialist nurses (with 95% confidence intervals of 1.91-23.23, 16.25-31.48, 1.05-19.09, and 6.72-31.82, unstandardized coefficient values of 12.57, 23.86, 10.07, and 19.27, respectively, P<0.05 or P<0.01). Conclusions: The humanistic care ability of burn specialist nurses is relatively weak. Age, professional title, working years, and whether received humanistic care training are the independent influencing factors of humanistic care ability of burn specialist nurses.

Background: Subclinical hypothyroidism (SCH) is the most common thyroid dysfunction, and its relationship with blood pressure (BP) has been controversial. The aim of the study was to analyze the association between SCH and newly-diagnosed hypertension. Methods: Based on data from the Thyroid disease, Iodine nutrition and Diabetes Epidemiology (TIDE) study, 49,433 euthyroid individuals and 7,719 SCH patients aged ≥18 years were enrolled. Patients with a history of hypertension or thyroid disease were excluded. SCH was determined by manufacturer reference range. Overall hypertension and stage 1 and 2 hypertension were diagnosed according to the guidelines issued by the American College of Cardiology/American Heart Association in 2017. Results: The prevalence of overall hypertension (48.7%), including stage 1 (28.9%) and 2 (19.8%) hypertension, increased significantly in SCH patients compared with euthyroid subjects. With elevated serum thyroid stimulating hormone (TSH) level, the hypertension prevalence also increased significantly from the euthyroid to different SCH subgroups, which was more profound in females or subjects aged <65 years. The age- and sex-specific regression analysis further demonstrated the same trends in the general population and in the 1:1 propensity matched population. Similarly, several BP components (i.e., systolic, diastolic, and mean arterial BP) were positively associated with TSH elevation, and regression analysis also confirmed that all BP components were closely related with SCH in female subjects aged <65 years. Conclusion The prevalence of hypertension increases for patients with SCH. SCH tends to be associated with hypertension and BP components in females younger than 65 years.

Objective: To investigate the positive rate for 2019-nCoV tests and co-infections in Wuhan district. Methods: A total of 8 274 cases in Wuhan were enrolled in this cross-sectional study during January 20 to February 9, 2020, and were tested for 2019-nCoV using fluorescence quantitative PCR. Both respiratory tract samples (nasopharynx, oropharynx, sputum and alveolar lavage fluid) and non-respiratory tract samples (urine, feces, anal swabs, blood and conjunctival sac swabs) were collected. If both orf1ab and N genes are positive, they are classified as nucleic acid test positive group; if both orf1ab and N genes are negative, they are classified as negative group; if single gene target is positive, they are classified as suspicious group. Individuals were divided into male group and female group according to sex. At the same time, 316 patients were tested for 13 respiratory pathogens by multiplex PCR. Results: Among the 8 274 subjects, 2 745 (33.2%) were 2019-nCoV infected; 5 277 (63.8%) subjects showed negative results in the 2019-nCoV nucleic acid test; and 252 cases (3.05%) was not definitive (inconclusive result). The age of cases with COVID-19 patients and inconclusive cases was significantly higher than that of cases without 2019-nCoV infection (40 vs 56, t=27.569, P<0.001; 52 vs 56, t=6.774, P<0.001). The positive rate of 13 respiratory pathogens multiple tests was significantly lower in 104 subjects who were positive for 2019-nCoV compared with those in subjects who were negative for 2019-nCoV test (5.77% vs 18.39%, χ²=24.105, P=0.003). Four types of respiratory tract samples and five types of non-respiratory tract samples were found to be positive for 2019-nCoV nucleic acid test. Conclusion The 2019-nCoV nucleic acid positive rate in male is higher than in female. Co-infections should be pay close attention in COVID-19 patients. 2019-nCoV nucleic acid can be detected in non-respiratory tract samples.

In recent years, as the level of economic life has improved, the incidence of gestational diabetes mellitus has increased year by year. Gestational diabetes mellitus (GDM) has been a serious threat to maternal and newborn health. The pathogenesis of gestational diabetes is not very clear, and may be closely associated with insulin resistance, genetic susceptibility, inflammatory response, metabolic disorders. According to the gestational diabetes diagnostic standard,24-28 weeks pregnant women keep an empty stomach over 8 h, taken 75 g oral glucose directly, and then receive the oral glucose tolerance test. GDM is diagnosed as fasting blood-glucose> 5.1 mmol · L^-1,1-hour postprandial blood glucose>10.0 mmol · L^-1,and 2-hour postprandial blood glucose>8.5 mmol · L^-1. Western medicine treatment is mainly based on diet, exercise, drugs, education, monitoring and insulin therapy according to blood glucose. Meanwhile, GDM is a type of diabetes in traditional Chinese medicine. GDM is prevented and treated with diets and traditional method sports and Chinese herbs. Therefore, integrated Chinese and western medicine therapy can maximize the curative effect, reduce the incidence of gestational diabetes mellitus, and effectively improve the adverse outcome and prognosis of patients with gestational diabetes mellitus from mother to child.

Objective To retrospectively study the biodistribution of 68Ga-DOTA-TATE as a SSTR imaging agent in human subjects.Methods A total of 106 patients with suspected disease were enrolled in this study.All patients were histologically proven for having either a single tumor ＜2 cm or without evidence of tumor during follow-up.Patients underwent PET/CT whole-body scan 17-100 min after intravenous injection of 55.2-220.0 MBq 68Ga-DOTA-TATE.ROI was drawn for measuring SUV of tracer-avid pathologies.One-way analysis of variance and two-sample t test were used for statistical analysis.Results High 68Ga-DOTA-TATE avidity was found in pituitary,with SUVmax of 4.00± 1.21.Tracer was excreted mainly through urinary system resulting in highest uptake in the urinary tracts.The SUVmax of kidney cortex was 19.01 ± 5.45.Mediastinal blood pool and liver SUVmax were 0.93±0.33 and 7.69±2.26,respectively.Mild uptake of 68Ga-DOTA-TATE was found in the brain,cerebellum,lung and muscle,all lower than that of mediastinal blood pool.Moderate accumulation of 68 Ga-DOTA-TATE (close to or slightly higher than liver) was found in adrenal gland and spleen,with SUVmax 7.61 ± 3.42 and 8.63± 2.31,respectively.Other organs (pituitary,salivary gland,thyroid,pancreas,small intestine,colon,uterus,prostate and bone) showed tracer uptake in the range between those of mediastinal blood pool and liver.68Ga-DOTA-TATE distribution in pancreas was not uniform.Nine patients had focal accumulation in the uncinate process of pancreas with highest SUVm~ up to 8.48.However,the SUVmax and SUV in the rest of pancreas (head,neck,body and tail) showed insignificant difference (F values:0.703,0.563,both P＞0.05).68Ga-DOTA-TATE uptake in each organ reached equilibrium quickly after injection but with slight increase over time.The changes in SUV,however,showed insignificant difference among organs,including different parts of pancreas (t values:from -0.09 to 1.75,from-1.70 to-0.42,respectively,all P＞0.05).Conclusions The biodistribution of 68Ga-DOTA-TATE reaches equilibrium shortly after intravenous administration and is stably maintained.The biodistribution activities are organ-specific,and characteristic to that of SSTR concentration.

Objective To investigate the characteristics of NEN metastasis with SSTR PET/CT and to correlate the results with FDG-PET and pathology.Methods From November 2011 to August 2016,a total of 43 patients with NEN (18 males,25 females;age range:26-74 years) were recruited into this retrospective study;they underwent 68Ga-DOTA-TATE PET/CT (TATE-PET) imaging 40-60 min after 44.4-229.4 MBq 68Ga-DOTA-TATE administration.Metastases in 31 patients were confirmed by histopathology and in 12 patients by follow-up and other imaging modalities.Twenty-eight of 43 patients finished routine FDG-PET in a week after TATE-PET.PET/CT results were considered positive when the metastatic lesions were tracer-avid.ROI was drawn over each lesion for size and SUV measurement.x2 test and Pearson correlation analysis were used for statistical analysis.Results (1) Of 43 patients,TATE-PET detection rates of metastasis in the liver,lymph nodes,bones.and lungs were 85.7％(30/35),12/13,7/7,2/3,respectively,with their corresponding SUVmax of 18.1(11.3-23.3),10.8(5.4-15.6),7.7(4.2-9.9) and 1.8(1.3-2.3),respectively.Statistical correlation between size and SUVmax was found in metastatic bone lesions(r=0.233,P＜0.05).(2) In 31 patients with histopathologically proven metastasis,TATE-PET detected 23/24 (95.8％) G2,1/2 G1 and 5/5 G3 metastases.G1 metastases were only found in the liver.(3)Among 28 patients underwent both TATE-PET and FDG-PET,there was no significant difference between the detecting rate of metastasis:89.2％ (25/28) vs 71.4％ (20/28);x2 =2.389,P＞0.05.Compared with FDG-PET,TATE-PET was superior in demonstrating metastasis in the liver and bones (70.0％ (14/20) vs 65.0％ (13/20),3/3 vs 2/3),equal in detecting lung metastasis (both 2/3) but inferior in demonstrating metastasis in lymph nodes (9/10vs 10/10).Conclusions The capability of TATE-PET in revealing NEN metastasis varies depending on lesion localization and histologic grade.TATE-PET and FDG-PET are complementary to each other in detection of NEN metastasis,but without obvious relationship to histologic grade.

OBJECTIVE: To investigate the changes of creatine kinase-MB (CK-MB) and heat shock protein 60 (HSP 60) in rats without electric marks after electric injury, to identify the relationship of the CK-MB, HSP 60 and the time of electric injuries, and to evaluate the damage to cells after electric injury. METHODS: The animal model of electric injury without electric marks was established by alternating current (voltage 110 V). Automatic biochemistry analyzer was used to detect the serum CK-MB and immunohistochemical staining technology was used to analyze the tissues of myocardium and left lobe of liver. RESULTS: The amount of serum CK-MB was increased when the rats were injuried, and reached the peak at 30min. Then the amount of CK-MB began to decrease and showed a slight downward trend in 3-5 h after electric injury, and leveled off at 6 h. Immunohistochemistry staining also showed the changes of HSP 60 of rats' myocardial cells and hepatic cells regularly after electric injury. CONCLUSION The regular changes of serum CK-MB and tissular HSP 60 in rats can be used to diagnosis electric injury and assess the injury of internal organs after the electric injury without electric marks.
