Objective To investigate the impact of the Shared Medical Appointment (SMA) model on blood glucose levels and self-management behaviors in patients with gestational diabetes mellitus (GDM). Methods A total of 87 pregnant women diagnosed with GDM at the Obstetrics and Gynecology and Endocrinology Outpatient Departments of the Affiliated Suqian Hospital of Xuzhou Medical University from October 2021 to October 2022 were enrolled and divided into treatment group (n=44) and control group (n=43). The treatment group received SMA-based GDM management, while the control group underwent routine outpatient follow-up. Baseline data, flash glucose monitoring (FGM)-related indicators before and after treatment, and self-management behavior scale scores were compared between the two groups. Results No statistically significant differences were observed between the two groups in age, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), blood urea nitrogen (BUN), creatinine (Cr), uric acid (UA), triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and glycated hemoglobin (HbA1c) (P>0.05). After treatment, the time in range (TIR) of glucose was higher in the treatment group than that in the control group, while mean amplitude of glycemic excursions (MAGE), standard deviation of blood glucose (SDBG), coefficient of variation (CV), and mean blood glucose (MBG) were lower in the treatment group (P < 0.05). Within the treatment group, post-treatment TIR was higher, and MAGE, CV, SDBG, and MBG were lower than pre-treatment levels (P < 0.05). In the control group, post-treatment TIR was higher, and SDBG and MBG were lower than pre-treatment levels (P < 0.05). After treatment, the total score and scores for dietary management, exercise management, medication management, and blood glucose monitoring management in the self-management behavior scale were significantly higher in the treatment group than in the control group (P < 0.05). In the treatment group, post-treatment scores for all self-management behaviors were higher than pre-treatment levels, while post-treatment total scores and scores for medication management and blood glucose monitoring management in the control group were higher than pre-treatment levels (P < 0.05). Conclusion SMA management model can comprehensively improve blood glucose levels and enhance self-management behavior capabilities in GDM patients.

Objective:To explore the influences of neutrophilic granule protein (NGP) on nitric oxide (NO) production in lipopolysaccharide (LPS)-induced macrophages and the regulatory mechanism.Methods:NGP highexpression RAW264.7 cells (NGP/RAW) and negative control empty vector cells (NC/RAW), NGP knockout RAW264.7 cells (NGP KO/RAW) and wild-type cells (WT/RAW) were cultured in vitro. Cells in logarithmic phase were stimulated with 10 mg/L LPS (LPS group) or phosphate buffered saline (PBS group) respectively. The content of NO in the supernatant was detected by Griess method. The mRNA expression of inducible nitric oxide synthase (iNOS) was detected by quantitative reverse transcription-polymerase chain reaction (RT-qPCR). The protein expressions of iNOS and phosphorylated signal transducer and activator of transcription 1 (p-STAT1) were detected by Western blotting.Results:Compared with PBS group, iNOS mRNA and NO expression were significantly increased at different time after LPS stimulation, the mRNA expression of iNOS peaked at 12 hours after LPS stimulation (2 -ΔΔCt: 38.45±1.34 vs. 1.00±0.00 in NC/RAW cells, 56.24±2.41 vs. 1.45±0.30 in NGP/RAW cells, 37.84±1.52 vs. 1.00±0.00 in WT/RAW cells, 5.47±0.62 vs. 0.98±0.40 in NGP KO/RAW cells, all P < 0.05), and the production of NO peaked at 24 hours after LPS stimulation (μmol/L: 24.15±1.26 vs. 0.15±0.04 in NC/RAW cells, 58.80±2.11 vs. 0.18±0.02 in NGP/RAW cells, 25.04±1.80 vs. 0.16±0.02 in WT/RAW cells, 2.42±0.38 vs. 0.12±0.03 in NGP KO/RAW cells, all P < 0.05). After being stimulated by LPS, the expression of iNOS mRNA and NO in NGP/RAW cells were increased significantly compared with NC/RAW cells [iNOS mRNA (2 -ΔΔCt): 8.42±0.59 vs. 4.63±0.37 at 2 hours, 27.16±1.60 vs. 14.25±1.02 at 6 hours, 56.24±2.41 vs. 38.45±1.34 at 12 hours; NO (μmol/L): 4.12±0.25 vs. 2.23±0.17 at 6 hours, 16.50±1.52 vs. 6.35±0.39 at 12 hours, 58.80±2.11 vs. 24.15±1.26 at 24 hours, all P < 0.05]. At the same time, the protein expressions of p-STAT1 and iNOS were also significantly enhanced (p-STAT1/GAPDH: 4.26±1.84 vs. 1.00±0.32 at 0 hours, 20.59±4.97 vs. 0.93±0.21 at 2 hours, 141.99±10.99 vs. 11.17±2.11 at 6 hours; iNOS/GAPDH: 1.27±0.86 vs. 1.00±0.22 at 0 hours, 7.94±1.94 vs. 2.01±0.92 at 2 hours, 24.24±4.88 vs. 3.72±1.11 at 6 hours, all P < 0.05), indicating that NGP might increase the expression of iNOS by promoting the phosphorylation of the signal transducer and activator of transcription 1 (STAT1) pathway, thereby increasing the production of NO. After being stimulated by LPS, the expression of iNOS mRNA and NO in NGP KO/RAW cells were significantly lower than that of WT/RAW cells [iNOS mRNA (2 -ΔΔCt): 2.46±0.31 vs. 4.22±0.18 at 2 hours, 3.61±0.44 vs. 13.02±1.34 at 6 hours, 5.47±0.62 vs. 37.84±1.52 at 12 hours; NO (μmol/L): 1.22±0.19 vs. 2.01±0.12 at 6 hours, 1.60±0.44 vs. 5.15±0.62 at 12 hours, 2.42±0.38 vs. 25.04±1.80 at 24 hours, all P < 0.05]. It showed that iNOS activation was reduced after NGP knockout, which in turn reduced NO production. Conclusion:NGP can positively regulate NO production in activated macrophages by activating the STAT1/iNOS pathway.

PURPOSE: Details of patients hospitalized for asthma exacerbation in mainland China are lacking. To improve disease control and reduce economic burden, a large sample survey among this patient population is indispensable. This study aimed to investigate the clinical characteristics and outcomes of such patients.METHODS: A retrospective study was conducted on patients hospitalized for asthma exacerbation in 29 hospitals of 29 regions in mainland China during the period 2013 to 2014. Demographic features, pre-admission conditions, exacerbation details, and outcomes were summarized. Risk factors for exacerbation severity were analyzed.RESULTS: There were 3,240 asthmatic patients included in this study (57.7% females, 42.3% males). Only 28.0% used daily controller medications; 1,287 (39.7%) patients were not currently on inhaled corticosteroids. Acute upper airway infection was the most common trigger of exacerbation (42.3%). Patients with severe to life-threatening exacerbation tended to have a longer disease course, a smoking history, and had comorbidities such as hypertension, chronic obstructive pulmonary disease (COPD), and food allergy. The multivariate analysis showed that smoking history, comorbidities of hypertension, COPD, and food allergy were independent risk factors for more severe exacerbation. The number of patients hospitalized for asthma exacerbation varied with seasons, peaking in March and September. Eight patients died during the study period (mortality 0.25%).CONCLUSIONS: Despite enhanced education on asthma self-management in China during recent years, few patients were using daily controller medications before the onset of their exacerbation, indicating that more educational efforts and considerations are needed. The findings of this study may improve our understanding of hospital admission for asthma exacerbation in mainland China and provide evidence for decision-making.

Objective:To explore the effects of electronic nursing hand-over schedule based on "knowledge-to-action" frame and evidence-based nursing in orthopedics nursing.Methods:We selected 150 patients of the Department of Orthopedics at the Hangzhou First People's Hospital from May to October 2018 in control group with the traditional handover, and selected 150 patients from November 2018 to April 2019 in intervention group with the electronic nursing hand-over schedule based on "knowledge-to-action" frame and evidence-based nursing. We compared the quality of nursing hand-over between two groups.Results:The nursing hand-over time of intervention group and control group was (2.45±1.05) min and (5.17±1.26) min respectively with a statistical difference ( t=11.726, P<0.05) . In intervention group, there were no missing items in the nursing hand-over, and the incidence of nursing risk events was 1.33% (2/150) , and the qualified rate of nursing measures was 98.0% (147/150) which were better than those in control group with statistical differences (χ 2=4.252, 4.624, 4.795; P<0.05) . Conclusions:The electronic nursing hand-over schedule based on "knowledge-to-action" frame and evidence-based nursing can improve the quality of nursing hand-over for orthopedics patients.

Objective: To investigate the potential effects of cytochrome P450 1A1 (CYP1A1) in regulating macrophages polarize to M2 type and explore the molecular mechanism. Methods: All trials were completely randomized. ① Experiment 1: 6-8 weeks old healthy male C57BL/6J mice were collected, and primary peritoneal cells were extracted, then the cells were divided into phosphate buffered saline (PBS) group and interleukin-4 (IL-4) group. The cells in the IL-4 group were stimulated with 10 mg/L IL-4 (M2 macrophage inducer); and those in the PBS group were given with an equal amount of PBS. The mRNA expressions of intracellular M2 type polarized marker molecules including arginase-1 (Arg-1) and chitinase 3 like protein 1 (YM1) at 2, 4, 6 hours after IL-4 challenge were determined by quantitative reverse transcription-polymerase chain reaction (RT-qPCR). The phosphorylation of tyrosine protein kinase 1/signaling transcriptional and transduced activator 6 (JAK1/STAT6) signaling pathway and protein expressions of CYP1A1 and Arg-1 at 6, 12, 24 hours after IL-4 challenge were determined by Western Blot. ② Experiment 2: RAW264.7 cells with high expression CYP1A1 (CYP1A1/RAW) and their negative control cells (NC/RAW) were cultured in vitro. The cells in logarithmic growth phase were collected, and then they were divided into PBS control group and IL-4 group. The treatment method was the same as experiment 1. The phosphorylations of intracellular JAK1/STAT6 and phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) pathways in different cells at 1 hour and 2 hours after IL-4 challenge were determined by Western Blot. The mRNA and protein expressions of Arg-1 in different cells at 2 hours and 4 hours after IL-4 challenge were determined by RT-qPCR and Western Blot, respectively. Results: ① Experiment 1: after IL-4 challenge for 2 hours, the mRNA expressions of Arg-1 and YM1 in the primary peritoneal macrophages of mice were significantly increased as compared with the PBS control group [Arg-1 mRNA (2^-ΔΔCt): 1.75±0.82 vs. 1.00±0.21; YM1 mRNA (2^-ΔΔCt): 2.58±0.53 vs. 1.00±0.20, both P < 0.05] which indicated that IL-4 induced macrophage to M2 type polarization successfully. Meanwhile, the mRNA expression of CYP1A1 in polarized mouse peritoneal primary macrophages was also elevated as compared with the PBS control group, and peaked at 4 hours [CYP1A1 mRNA (2^-ΔΔCt): 2.25±0.69 vs. 1.00±0.17, P < 0.01]. The results indicated that CYP1A1 expression was enhanced when macrophages polarized to M2 type. Compared with the PBS control group, the bands of phosphorylated JAK1 (p-JAK1), phosphorylated STAT6 (p-STAT6), Arg-1 and CYP1A1 were enhanced in primary peritoneal macrophages of mice in the IL-4 group, and reached the peak value at 12 hours then gradually decreased. This result indicated that the phosphorylation of JAK1/STAT6 pathway was enhanced in M2 macrophages with high expression of CYP1A1, and the pathway was activated. ② Experiment 2: after IL-4 challenge for 2 hours, the expression of Arg-1 mRNA in CYP1A1/RAW cells was significantly higher than that in NC/RAW cells (2^-ΔΔCt: 3.02±0.60 vs. 1.47±0.43, P < 0.05), and the protein band signal was also stronger, and both peaked at 4 hours. This indicated that CYP1A1 could promote the polarization of macrophages to M2. After IL-4 challenge for 2 hours, the expression of p-JAK1 and p-JAK3 protein bands in both cells were significantly enhanced as compared with the PBS control group, but the enhancement of p-STAT6 band in CYP1A1/RAW cells was stronger than that of NC/RAW cells, indicating that CYP1A1 promoted macrophage polarization by promoting phosphorylation of the JAK1/STAT6 pathway. In the meantime, the protein band of Akt, a downstream protein of the PI3K/Akt pathway, in CYP1A1/RAW cells was significantly lower than that of NC/RAW cells, indicating that CYP1A1 did not promote macrophage polarization through this pathway. Conclusions CYP1A1 promotes the polarization of macrophage to M2 type. The mechanism is related to promoting the phosphorylation of JAK1/STAT6 pathway.

Objective To analyze the risk factors of patients with trauma in intensive care unit (ICU), a new warning scoring system is established for predicting the incidence of sepsis in traumatic patients; and to provide a new simple method of clinical score, which could provide a reference for clinical prevention and treatment of sepsis. Methods The clinical data of 591 patients with trauma in the ICU of the Army Specialized Medical Center of Army Medical University and Affiliated Hospital of Zunyi Medical University from January 2012 to December 2017 were retrospectively analyzed. The patients were divided into sepsis group (n = 382) and non-sepsis group (n = 209) according to their clinical outcome. The basic clinical data of all ICU trauma patients were collected, and the differences in gender, age, underlying diseases, and vital signs, critical illness scores, blood culture results and laboratory biochemical examinations within 24 hours of ICU admission between the two groups were analyzed. Univariate Logistic regression analysis was used to screen the related factors leading to sepsis. The indexes with P < 0.12 analyzed by univariate Logistic regression analysis were included in multivariate Logistic regression analysis. The risk factors of sepsis in traumatic patients were screened and assigned, and the total score was sepsis early warning score. The receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of the warning score of sepsis in patients with trauma. Results The incidence of sepsis in ICU trauma patients was 64.6% (382/591), and the ICU mortality was 10.5% (40/382). The traffic accident was a common cause of ICU trauma patients. Compared with non-sepsis patients, Glasgow coma score (GCS), proportion of past history, red blood cell (RBC), platelet (PLT), albumin (Alb) were lower in patients with sepsis, and body temperature, pulse, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), sequential organ failure assessment (SOFA), injury severity score (ISS), new injury severity score (NISS), fraction of inspired oxygen (FiO2), blood sodium, activated partial thromboplastin time (APTT), prothrombin time (PT), procalcitonin (PCT), C-reactive protein (CRP) levels were higher, blood transfusion, central venous catheterization, mechanical ventilation, shock, multiple organ dysfunction syndrome (MODS), open injury and multiple injuries were more common, the duration of mechanical ventilation, ICU days and total hospital days were longer, and all the differences were statistically significant. Most of the traumatic patients with sepsis were undergone with multiple trauma. Compared with non-sepsis patients, the proportion of multiple position trauma was significantly higher than patients without sepsis. And most traumatic patients were insulted in head, face and neck. The risk factors were screened by univariate and multivariate Logistic stepwise regression analysis, the indexes into the regression model were pulse > 100 bpm [odds ratio (OR) = 1.617, 95% confidence interval (95%CI) = 0.992-2.635, P = 0.044], APTT > 36 s (OR = 2.164, 95%CI =1.056-4.435, P = 0.035), shock (OR = 1.798, 95%CI = 1.056-3.059, P = 0.031), mechanical ventilation (OR = 5.144, 95%CI = 2.302-11.498, P < 0.001), APACHEⅡ > 21 (OR = 3.348, 95%CI = 1.724-6.502, P < 0.001), NISS > 25 (OR = 3.332, 95%CI = 1.154-9.624, P = 0.026), assigning scores were 0.5, 1.0, 0.5, 1.5, 1.5, 1.5, respectively, which were included in the new warning score of sepsis. ROC curve analysis showed that the area under ROC curve (AUC) of warning score for predicting sepsis in patients with trauma was 0.782, which was significantly higher than the APACHEⅡ(AUC = 0.672), APTT (AUC = 0.574) and NISS (AUC = 0.515) with significant difference (all P < 0.01). When the cut-off value of sepsis warning score was 4.0, the sensitivity and specificity were 71.7% and 61.9%, respectively. Conclusions Close monitoring and stabilization of vital signs of traumatic patients within 24 hours of ICU admission and reduction of unreasonable invasive mechanical ventilation time are expected to reduce the incidence of sepsis in traumatic patients. New warning score of sepsis consisted of six factors: pulse, APTT, shock, mechanical ventilation, APACHEⅡ and NISS. Rational use of warning score of sepsis would help us to assess the prognosis of traumatic patients more easily and effectively, and the predicted effect is much better than APACHEⅡ, APTT and NISS.

Objective: To determine the clinical significance of nontuberculous mycobacteria (NTM) isolated from respiratory specimens. Methods: Clinical data of patients with NTM strains isolated from the respiratory tract between January 2014 and February 2017 were retrospectively analyzed. Clinical significance of NTM isolated strains was evaluated based on diagnostic criteria of NTM pulmonary diseases from American Thoracic Society (ATS). Quantitative data of two groups were analyzed by independent t test. Categorical data were analyzed by Pearson χ² test or Fisher exact test. Results: Totally 352 NTM strains from 257 patients had been isolated between January 2014 and February 2017. Among 15 identified NTM species, M. intracellular (51.7%, 182/352), M. abscessus (25.6%, 90/352), and M. avium (10.8%, 38/352) were predominant. Of the 157 patients with full clinical data involved in the analysis, 58 (36.9%) patients were determined to have definite disease, and 34 patients (21.7%) were designated as probable disease candidates, and 16 (10.2%) patients were regarded as uncertain disease, and 49(31.2%) patients were diagnosed as unlikely disease. The age of 58 patients with definite disease was (63.9±12.7) years, and 48.3% (28/58) were female. M. intracellulare (55.2%, 32/58) was the main cause of pulmonary NTM disease, followed by M. abscessus (25.9%, 15/58) and M. avium (12.1%, 7/58), while other NTM species only accounted for 6.8% (4/58). Definite cases with M. intracellulare, M. abscessus, M. avium, M. kansasii, M. marseillense, and M. columbia accounted for 35.2% (32/91), 57.7% (15/26), 7/15, 2/3, 1/3 and 1/2, respectively, among patients with corresponding isolations, while patients with other species of isolation did not meet the diagnostic criteria. Patients with clinical significant isolation of NTM were older than those without clinical significance (χ²=3.603, P=0.000), and proportion of anti-acid staining positivity of patients with clinical significance was higher than that of patients without clinical significance (χ²=18.815, P=0.000). The proportion of M. abscessus in patients with clinical significance was higher than that in patients without clinical significance (χ²=6.313, P=0.012). However, there was no significant difference between the two groups in the isolation of M. Gordon (Fisher exact test, P=0.028). The proportion of M. abscessus lung disease in women was 11/15, which was higher than that of M. intracellulare lung disease (41.5%, 17/41), and the difference between the two groups was statistically significant (χ²=4.462, P=0.035). There was no significant difference of clinical symptoms and underlying diseases in NTM lung disease among different groups (all P>0.05). In these patients with definite disease, 39.7% (23/58) of them manifested the upper lobe cavitary form, 53.4% (31/58) exhibited nodular bronchiectatic form, and only 6.9% (4/58) exhibited unclassified form. The upper lobe cavitary form (43.8%, 14/32) and the nodular bronchiectatic form (53.1%, 17/32) dominated in patients with M. intracellulare lung disease. M. abscessus lung disease was dominated by the nodular bronchiectatic form (11/15) while the upper lobe cavitary form only accounts for 3/15. There was no significant difference of image characteristics between NTM lung disease and other different groups (all P>0.05). Conclusions 36.9% of the patients with NTM isolates met the ATS diagnostic criteria for NTM lung disease. Different species have different clinical significance. M. intracellulare and M. abscessus are the most predominant NTM isolated species that cause NTM lung disease. Majority of patients manifest as the upper lobe cavitary form, followed by the nodular bronchiectatic form.
