Effects of breast milk intake ratio during hospitalization on antibiotic therapy duration in preterm infants less than 34 gestational weeks: a multicenter retrospective cohort study / 中华围产医学杂志

Objective:To investigate the effects of breast milk to total milk intake ratio during hospitalization on the duration of antibiotic therapy in preterm infants less than 34 weeks of gestation.Methods:Clinical data of preterm infants ( n=1 792) less than 34 gestational weeks were retrospectively collected in 16 hospitals of Jiangsu Province Neonatal-Perinatal Cooperation Network from January 1, 2019, to December 31, 2021. The days of therapy (DOT) were used to evaluate the duration of antibiotic administration. The median DOT was 15.0 d (7.0-27.0 d). The patients were divided into four groups based on the quartiles of DOT: Q 1 (DOT≤7.0 d), Q 2 (7.0 d<DOT≤15.0 d), Q 3 (15.0 d<DOT≤27.0 d) and Q 4 (DOT>27.0 d) groups. According to the breast milk intake ratio (breast milk intake to total milk intake during hospitalization×100%), they were also divided into four groups: very-low-ratio breastfeeding group (breast milk intake ratio≤25%), low-ratio breastfeeding group (25%<breast milk intake ratio≤50%), medium-ratio breastfeeding group (50%<breast milk intake ratio≤75%) and high-ratio breastfeeding group (breast milk intake ratio>75%). Univariate analysis ( Chi-square test and Kruskal-Wallis rank-sum test) was used to analyze the factors influencing DOT. Spearman correlation analysis and trend Chi-square test were used to explore the relationship between breast milk intake ratio and DOT. After using multiple imputations to address missing data, two models were constructed after adjusting for different factors, and multinomial logistic regression model was applied to evaluate the effects of the breast milk intake ratio on DOT. Finally, sensitivity analysis was conducted to assess the stability of the models. Results:(1) Of the 1 792 preterm infants, there were 507 (28.3%) in the Q 1 group, 422 (23.5%) in the Q 2 group, 438 (24.4%) in the Q 3 group and 425 (23.7%) in the Q 4 group. (2) The median values of DOT in the very-low-ratio, low-ratio, medium-ratio and high-ratio breastfeeding groups were 20.0 d (11.0-31.0 d), 20.0 d (11.0-32.0 d), 13.0 d (6.0-25.8 d) and 10.0 d (4.0-21.0 d), respectively. Compared with the very-low-ratio and low-ratio breastfeeding groups, the medium-ratio and high-ratio breastfeeding groups had shorter DOT (all P<0.05). (3) After adjusting for factors with P<0.1 (prenatal glucocorticoid exposure, antimicrobial use within 24 h before delivery, gestational age at delivery, birth weight, Apgar score≤7 at 1 min, neonatal respiratory distress syndrome, infectious pneumonia and early-onset neonatal sepsis) between the DOT quartile groups, it showed that medium-ratio and high-ratio breastfeeding were protective factors in contrast to very-low-ratio breastfeeding in the Q 2, Q 3 and Q 4 groups as compared with the Q 1 group [Q 2 group: OR=0.50 (95% CI: 0.30-0.85) and OR=0.36 (95% CI: 0.26-0.51); Q 3 group: OR=0.31 (95% CI: 0.18-0.55) and OR=0.20 (95% CI: 0.14-0.29); Q 4 group: OR=0.22 (95% CI: 0.12-0.42) and OR=0.17 (95% CI: 0.12-0.26)]. Conclusion:Breast milk intake accounting for over 50% of total milk intake has a positive impact on reducing DOT in premature infants requiring antibiotics, which suggests that breastfeeding should be actively encouraged.

Clinical features and management analysis of 11 cases of laryngocele / 中华耳鼻咽喉头颈外科杂志

Objective: To summarize clinical features and our experience of the diagnosis and treatment of laryngocele. Methods: Clinical data of 11 laryngocele patients in department of Otorhinolaryngology Head and Neck Surgery of the Second Affiliated Hospital of Shanxi Medical University from January 2012 to December 2021 were retrospectively reviewed, including 9 men and 2 women, aged from 12 to 75 years, with median age of 56 years. Electronic laryngoscope was performed in 10 of all patients, laryngeal CT in 10 and cervical color ultrasound in 5 before operation.All the operations were performed under general anesthesia, and the external cervical approach was used for external and combined laryngocele. The internal laryngocele was resected by low temperature plasma through transoral endoscopy. Patients were followed up regularly after operation to evaluate the effect. Clinical feature, types of lesions, imaging findings, surgical approaches and follow-up results were analyzed through descriptive statistical method. Results: Eleven laryngocele patients were divided into mixed type (n=6), internal type (n=4) and external type (n=1).Nine patients presented with hoarseness or dysphonia, 7 with cervical mass and 1 with airway obstruction. Surgical resections were done through external cervical approach (n=7)or transoral endoscopic approach (n=4). All the operations were successful and no complication occurred. All cases were followed up from 17 to 110 months. No recurrence was encountered. Conclusions: Laryngocele is a rare lesion with atypical clinical presentation. Preoperative imaging including CT scan and electronic laryngoscope is essential to evaluate the location, and extent of the lesion, and to make the surgical plan.Complete surgical excision is required. Surgical resection is the only effective method for the treatment of laryngocele.

Antiarrhythmic drugs (AADs) are the first-line treatment for rhythm-control strategies. This consensus focuses on the principle of rhythm control in AF, the characteristics of AADs, and the medication recommendations for patients in different populations suffering from AF. Hence, this consensus aims to support clinical decision-making for AF therapy.

Prevalence and incidence of heart failure among community in China during a three-year follow-up / 老年心脏病学杂志（英文版）

BACKGROUND@#Epidemiological surveys on heart failure (HF) in Chinese community are relatively lacking. This study aimed to estimate the prevalence and incidence of HF among community residents in southern China.@*METHODS@#Baseline data of this prospective study was collected from 2015 to 2017 among 12,013 permanent residents aged ≥ 35 years in Guangzhou, China. The same survey process was carried out for individuals aged ≥ 65 years after a three-year follow-up.@*RESULTS@#The overall prevalence of HF in community residents aged ≥ 35 years was 1.06%. Male had significantly higher risk of HF prevalence [odds ratio (OR) = 1.50, P = 0.027]. The gender-adjusted risk of HF was 1.48 times higher per 10 years aging. HF prevalence was statistically associated with atrial fibrillation, valvular heart disease, hypertension and chronic obstructive pulmonary disease after adjusting for age and gender (OR = 8.30, 5.17, 1.11, 2.28, respectively; all P < 0.05). HF incidence in individuals aged ≥ 65 years were 847 per 100,000 person-years. Baseline atrial fibrillation, valvular heart disease, and diabetes mellitus were risk factors for HF incidence for individuals aged ≥ 65 years adjusting for age and gender (OR = 5.05, 3.99, 2.11, respectively; all P < 0.05). Besides, residents with new-onset atrial fibrillation and myocardial infarction were at significantly higher risk of progression to HF (OR = 14.41, 8.54, respectively; all P < 0.05).@*CONCLUSIONS@#Both pre-existing and new-onset cardiovascular diseases were associated with HF incidence in southern China. Management of related cardiovascular diseases may be helpful to reduce the incidence of HF.

Clinical effect of different maintenance doses of caffeine citrate in the treatment of preterm infants requiring assisted ventilation: a pilot multicenter study / 中国当代儿科杂志

OBJECTIVES@#To explore the optimal maintenance dose of caffeine citrate for preterm infants requiring assisted ventilation and caffeine citrate treatment.@*METHODS@#A retrospective analysis was performed on the medical data of 566 preterm infants (gestational age ≤34 weeks) who were treated and required assisted ventilation and caffeine citrate treatment in the neonatal intensive care unit of 30 tertiary hospitals in Jiangsu Province of China between January 1 and December 31, 2019. The 405 preterm infants receiving high-dose (10 mg/kg per day) caffeine citrate after a loading dose of 20 mg/kg within 24 hours after birth were enrolled as the high-dose group. The 161 preterm infants receiving low-dose (5 mg/kg per day) caffeine citrate were enrolled as the low-dose group.@*RESULTS@#Compared with the low-dose group, the high-dose group had significant reductions in the need for high-concentration oxygen during assisted ventilation (P=0.044), the duration of oxygen inhalation after weaning from noninvasive ventilation (P<0.01), total oxygen inhalation time during hospitalization (P<0.01), the proportion of preterm infants requiring noninvasive ventilation again (P<0.01), the rate of use of pulmonary surfactant and budesonide (P<0.05), and the incidence rates of apnea and bronchopulmonary dysplasia (P<0.01), but the high-dose group had a significantly increased incidence rate of feeding intolerance (P=0.032). There were no significant differences between the two groups in the body weight change, the incidence rates of retinopathy of prematurity, intraventricular hemorrhage or necrotizing enterocolitis, the mortality rate, and the duration of caffeine use (P>0.05).@*CONCLUSIONS@#This pilot multicenter study shows that the high maintenance dose (10 mg/kg per day) is generally beneficial to preterm infants in China and does not increase the incidence rate of common adverse reactions. For the risk of feeding intolerance, further research is needed to eliminate the interference of confounding factors as far as possible.

Preoperative prediction of Ki-67 expression status in breast cancer based on dynamic contrast enhanced MRI radiomics combined with clinical imaging features model / 中华放射学杂志

Objective:To investigate the value of preoperative prediction of Ki-67 expression status in breast cancer based on multi-phase enhanced MRI combined with clinical imaging characteristics prediction model.Methods:This study was retrospective. A total of 213 breast cancer patients who underwent surgical treatment at Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between June 2016 and May 2017 were enrolled. All patients were female, aged 24-78 (51±10) years, and underwent routine breast MRI within 2 weeks prior to surgery. According to the different Ki-67 expression of postoperative pathological results, patients were divided into high expression group (Ki-67≥20%, 153 cases) and low expression group (Ki-67<20%, 60 cases). The radiomic features of breast cancer lesions were extracted from phase 2 (CE-2) and phase 7 (CE-7) images of dynamic contrast enhanced (DCE)-MRI, and all cases were divided into training and test sets according to the ratio of 7∶3. The radiomic features were first selected using ANOVA and Wilcoxon signed-rank test, followed by the least absolute shrinkage and selection operator method regression model. The same method of parameters selection was applied to clinical information and conventional imaging features [including gland classification, degree of background parenchymal enhancement, multifocal/multicentric, lesion location, lesion morphology, lesion long diameter, lesion short diameter, T 2WI signal characteristics, diffusion-weighted imaging (DWI) signal characteristics, apparent diffusion coefficient (ADC) values, time-signal intensity curve type, and axillary lymph nodes larger than 1 cm in short axis]. Support vector machine (SVM) was then used to construct prediction models for Ki-67 high and low expression states. The predictive performance of the models were evaluated using receiver operating characteristic (ROC) curves and area under cueve(AUC). Results:Totally 1 029 radiomic features were extracted from CE-2 and CE-7 images, respectively, and 9 and 7 best features were obtained after selection, respectively. And combining the two sets of features for a total of 16 features constituted the CE-2+CE-7 image best features. Five valuable parameters including lesion location, lesion short diameter, DWI signal characteristics, ADC values, and axillary lymph nodes larger than 1 cm in short axis, were selected from all clinical image features. The SVM prediction models obtained from the radiomic features of CE-2 and CE-7 images had a high AUC in predicting Ki-67 expression status (>0.70) in both the training set and the test set. The models were constructed by combining the CE-2, CE-7, and CE-2+CE-7 radiomic features with clinical imaging features, respectively, and the corresponding model performance in predicting Ki-67 expression status was improved compared with the models obtained by using the CE-2, CE-7, and CE-2+CE-7 radiomic features alone. The SVM prediction model obtained from CE-2+CE-7 radiomic features combined with clinical imaging features had the best prediction performance, with AUC of 0.895, accuracy of 84.6%, sensitivity of 87.9%, and specificity of 76.2% for predicting Ki-67 expression status in the training set and AUC of 0.822, accuracy of 70.3%, sensitivity of 76.1%, and specificity of 55.6% in test sets.Conclusion:The SVM prediction model based on DCE-MRI radiomic features can effectively predict Ki-67 expression status, and the combination of radiomic features and clinical imaging features can further improve the model prediction performance.

OBJECTIVES@#To investigate the preadmission follow-up condition of neonates hospitalized due to severe hyperbilirubinemia after discharge from the department of obstetrics and the influencing factors for follow-up compliance.@*METHODS@#A multicenter retrospective case-control study was performed for the cases from the multicenter clinical database of 12 units in the Quality Improvement Clinical Research Cooperative Group of Neonatal Severe Hyperbilirubinemia in Jiangsu Province of China from January 2019 to April 2021. According to whether the follow-up of neonatal jaundice was conducted on time after discharge from the department of obstetrics, the neonates were divided into two groups: good follow-up compliance and poor follow-up compliance. The multivariate logistic regression model was used to identify the influencing factors for follow-up compliance of the neonates before admission.@*RESULTS@#A total of 545 neonates with severe hyperbilirubinemia were included in the study, with 156 neonates (28.6%) in the good follow-up compliance group and 389 (71.4%) in the poor follow-up compliance group. The multivariate logistic regression analysis showed that low gestational age at birth, ≥10% reduction in body weight on admission compared with birth weight, history of phototherapy of siblings, history of exchange transfusion of siblings, Rh(-) blood type of the mother, a higher educational level of the mother, the use of WeChat official account by medical staff to remind of follow-up before discharge from the department of obstetrics, and the method of telephone notification to remind of follow-up after discharge were associated with the increase in follow-up compliance (P<0.05).@*CONCLUSIONS@#Poor follow-up compliance is observed for the neonates with severe hyperbilirubinemia after discharge from the department of obstetrics, which suggests that it is necessary to further strengthen the education of jaundice to parents before discharge and improve the awareness of jaundice follow-up. It is recommended to remind parents to follow up on time by phone or WeChat official account.

In the follow-up audit, except criterion 4 and 10, the compliance of the remaining 8 criteria had significantly improved, and χ2 value was 10.29-132.06, P<0.01. The result of history adverse reaction in the follow-up audit showed that among 68 patients, 3 had experienced chemotherapy infusion reactions in the past (The drugs were oxaliplatin, gemcitabine and paclitaxel), 39 had chemotherapy-related symptoms before admission (most of them were relieved at admission), of which the top five were loss of appetite, fatigue, nausea, neurotoxicity and vomiting. Conclusions:The aims of the project were fulfilled. We achieved increased compliance with evidence-based best practice recommended by JBI in most of audit criteria. Further audit will need to be carried out to improve the validity and quality of nursing assessment.

Panax Notoginseng Saponin Attenuates Gastric Mucosal Epithelial Cell Injury Induced by Dual Antiplatelet Drugs through COX and PI3K/Akt/ VEGF-GSK-3β-RhoA Network Pathway / 中国结合医学杂志

OBJECTIVE@#To elucidate the underlying mechanism of Panax notoginseng saponin (PNS) on gastric epithelial cell injury and barrier dysfunction induced by dual antiplatelet (DA).@*METHODS@#Human gastric mucosal epithelial cell (GES-1) was cultured and divided into 4 groups: a control, a DA, a PNS+DA and a LY294002+PNS+DA group. GES-1 apoptosis was detected by flow cytometry, cell permeability were detected using Transwell, level of prostaglandins E2 (PGE2), 6-keto-prostaglandin F1α (6-keto-PGF1α) and vascular endothelial growth factor (VEGF) in supernatant were measured by enzyme linked immunosorbent assay (ELISA), expression of phosphatidylinositide 3-kinase (PI3K), phosphorylated-PI3K (p-PI3K), Akt, phosphorylated-Akt (p-Akt), cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2), glycogen synthase kinase-3β (GSK-3β) and Ras homolog gene family member A (RhoA) were measured by Western-blot.@*RESULTS@#DA induced apoptosis and hyper-permeability in GES-1, reduced supernatant level of PGE2, 6-keto-PGF1α and VEGF (P<0.05). Addition of PNS reduced the apoptosis of GES-1 caused by DA, restored the concentration of PGE2, 6-keto-PGF1α and VEGF (P<0.05). In addition, PNS attenuated the alteration of COX-1 and COX-2 expression induced by DA, up-regulated p-PI3K/p-Akt, down-regulated RhoA and GSK-3β. LY294002 mitigated the effects of PNS on cell apoptosis, cell permeability, VEGF concentration, and expression of RhoA and GSK-3β significantly.@*CONCLUSIONS@#PNS attenuates the suppression on COX/PG pathway from DA, alleviates DA-induced GES-1 apoptosis and barrier dysfunction through PI3K/Akt/ VEGF-GSK-3β-RhoA network pathway.

Clinical features of preterm infants with a birth weight less than 1 500 g undergoing different intensities of resuscitation: a multicenter retrospective analysis / 中国当代儿科杂志

OBJECTIVE@#To evaluate the clinical features of preterm infants with a birth weight less than 1 500 g undergoing different intensities of resuscitation.@*METHODS@#A retrospective analysis was performed for the preterm infants with a birth weight less than 1 500 g and a gestational age less than 32 weeks who were treated in the neonatal intensive care unit of 20 hospitals in Jiangsu, China from January 2018 to December 2019. According to the intensity of resuscitation in the delivery room, the infants were divided into three groups:non-tracheal intubation (@*RESULTS@#Compared with the non-tracheal intubation group, the tracheal intubation and ECPR groups had significantly lower rates of cesarean section and use of antenatal corticosteroid (@*CONCLUSIONS@#For preterm infants with a birth weight less than 1 500 g, the higher intensity of resuscitation in the delivery room is related to lower rate of antenatal corticosteroid therapy, lower gestational age, and lower birth weight. The infants undergoing tracheal intubation or ECRP in the delivery room have an increased incidence rate of adverse clinical outcomes. This suggests that it is important to improve the quality of perinatal management and delivery room resuscitation to improve the prognosis of the infants.

Comparison of the accuracy of RIFLE, AKIN and KDIGO criteria in predicting early death after liver transplantation / 器官移植

Objective To compare the accuracy of three acute kidney injury (AKI) criteria of RIFLE, Acute Kidney Injury Network (AKIN) and Kidney Disease: Improving Global Outcomes (KDIGO) in predicting the early (30 d) postoperative death of liver transplant recipients. Methods Clinical data of 173 liver transplant recipients were retrospectively analyzed. The incidence of postoperative AKI was calculated according to the three criteria of RIFLE, AKIN and KDIGO. The all-cause fatality rate and cause of death at postoperative 30 d were analyzed. The risk factors of death within 30 d after operation were analyzed by binary Logistic regression. The prediction accuracy of three criteria for death within 30 d after operation was compared by the receiver operating characteristic (ROC) curve. Results According to the RIFLE, AKIN and KDIGO criteria, the incidences of postoperative AKI were 48.0%, 51.4% and 53.8%, respectively. Thirteen patients died within 30 d after operation and the fatality rate was 7.5%. RIFLE, AKIN and KDIGO stages were the independent risk factors for death within 30 d after operation (all P < 0.05). The area under the curve (AUC) of RIFLE, AKIN and KDIGO stages to predict death within 30 d after liver transplantation were 0.828, 0.766 and 0.844, respectively. There was a statistically significant difference between AKIN and KDIGO (P < 0.05). Conclusions KDIGO criterion is better for predicting early death after liver transplantation. However, as a tool, the comparative selection among these three criteria still needs the evidence support from a large multicenter sample.

Involvement of Src kinase in the down-regulation of ultra-rapid delayed rectifier K(+)current induced by tumor necrosis factor-α in cardiomyocytes / 中华心血管病杂志

Objective: To investigate whether inflammatory factor tumor necrosis factor-α (TNF-α) is involved in the electrical remodeling of cardiomyocytes by regulating ultra-rapid delayed rectifier K(+) current (I(kur)) and the role of Src kinase. Methods: H9c2 cells, embryonic cardiomyocytes of rat, were cultured in Dulbecco's modified Eagle's medium (DMEM) and atrium-derived HL-1 cells were cultured in Claycomb medium. Both H9c2 and HL-1 cells were cultured at 37 ℃ with 5% CO(2). Cells cultured in normal conditions without additional treatment served as control group. Experimental groups were treated with different concentration of TNF-α (25 or 50 or 100 ng/ml) for 24 hours. To study whether Src specific inhibitor PP1 could abrogate the effect of TNF-α, cells were pre-treated with 10 μmol/L PP1 for 1 hour, followed by TNF-α (100 ng/ml) for 24 hours. Western blot and the whole cell patch clamp technique were used to detect the protein expression of Kv1.5 and Src and I(kur) in each group. Results: (1) In H9c2 cells, high concentration of TNF-α treatment (100 ng/ml) significantly reduced the Kv1.5 protein expression compared with control group and TNF-α 25 ng/ml group (both P<0.05). Compared with control group, the expression of p-Src protein was higher in 25 ng/ml, 50 ng/ml, 100 ng/ml TNF-α group (all P<0.05), but there was no statistical difference in the expression of Src protein among groups (P>0.05). In addition, the current density of I(kur) was decreased in 50 ng/ml, 100 ng/ml TNF-α group (both P<0.05). Furthermore, the expression of Kv1.5 protein and the current density of I(kur) were increased in PP1+TNF-α group compared with TNF-α 100 ng/ml group (both P<0.05). There was no statistical difference in the expression of Kv1.5 protein and the current density of I(kur) between the control group and PP1+TNF-α group (both P>0.05). (2) In atrium-derived HL-1 cells, the expression of Kv1.5 protein was reduced in 100 ng/ml TNF-α group compared with control group and TNF-α 25 ng/ml group (both P<0.01). In addition, the expression of p-Src protein was increased in TNF-α 100 ng/ml group compared with control group (P<0.05), but there was no statistical difference in the protein expression of Src among groups (P>0.05). The expression of Kv1.5 protein was increased in PP1+TNF-α group compared with TNF-α 100 ng/ml group (P<0.05). Conclusion: TNF-α is involved in the pathogenesis of atrial fibrillation, probably via decreasing I(kur) current density in atrium-derived myocytes through the activation of Src kinase.

HPLC Fingerprint of Bletillae Formosanae Rhizoma / 中国实验方剂学杂志

Objective: To study the chemical constituents of Bletillae Formosanae Rhizoma and the distribution characteristics of active components in the fingerprint by establishing its high performance liquid chromatography (HPLC) fingerprints. Method: HPLC was used to establish the fingerprint of Bletillae Formosanae Rhizoma. Four reference substances,i.e. militarine,coelonin,4-methoxy-9,10-dihydrophenanthrene-1,2,7-triol and batatasin Ⅲ were used to identify chromatographic peaks. The fingerprints of 17 batches of Bletillae Formosanae Rhizoma fingerprints were analyzed and compared by "Computer-aided-similarity evaluation soft" and stoichiometry,and then compared with the fingerprint of Bletillae Rhizoma. Result: The established HPLC fingerprint method of Bletillae Formosanae Rhizoma showed good repeatability and stability. 20 common peaks were marked,four of which were identified by reference substances; militarine was No.8 common peak,and others corresponded to No. 10, No. 14 and No. 18 common peaks. Results showed that the similarities of samples except S4 were higher than 0.85, but the relative peak area of common peaks was quite different. Within the cluster distance 10,the samples are clustered into 5 categories, reflecting certain origin correlation. Principal component analysis (PCA) showed that the difference in samples was mainly caused by the common peaks located after No. 9 peak,where chemical constituents such as bibenzyl and dihydrophenanthrene were distributed. Bletillae Formosanae Rhizoma and Bletillae Rhizoma showed similar chemical constituents. Conclusion: The method provided a theoretical basis for the further clinical application and quality control of Bletillae Formosanae Rhizoma,as a substitute for Bletillae Rhizoma.

Mental Health Status and Its Influencing Factors in the Floating Population in Chengdu / 中国医学科学院学报

To investigate the mental health status of the floating population in Chengdu and explore its influencing factors. A questionnaire-based survey was conducted on non-Chengdu household workers over 16 years old in four directions(east,south,west,and north)of Chengdu from June 2017 to June 2018 to collect their social demographic characteristics and mental health status information through respondent driven sampling method.The 12-item general health questionnaire(GHQ-12) was used to assess the mental health status of the respondents,and a multivariate logistic regression model was used to analyze the influencing factors of mental health. The average score of GHQ-12 was(1.09±1.61)and the detection rate of mental problems was 7.11%.The main mental problems were anxiety and nervousness.Multivariate unconditional logistic regression analysis showed that over 55 years old(=0.425,95%=0.213-0.847),junior middle school education(=0.541,95%=0.356-0.824),length of residence ≥5 years(5-9 years:=0.603,95%=0.394-0.923;≥10 years:=0.534,95%=0.346-0.823),annual income ≥18 000 yuan(18 000-35 999 yuan:=0.524,95%=0.328-0.836;36 000-59 999 yuan:=0.327,95%=0.190-0.565;≥60 000 yuan: =0.356,95%=0.192-0.662),and a good relationship with employers(=0.519,95%=0.363-0.742)were the protective factors for the mental health.Divorce/widowhood(=2.351,95%=1.341-4.124),plan to return hometown after 5 years(=1.805,95%=1.084-3.006)and not yet consideration of leaving Chengdu(=1.844,95%=1.269-2.681)were the risk factors. The mental health of the floating population in Chengdu is generally good.However,floating individuals with poor marital status and/or poor sense of belonging to Chengdu are at higher risk of mental problems.The local government should formulate and improve the policies and measures related to social welfare and public services for the floating population and try to enhance their urban integration and sense of belonging,thus improving their mental health.

To explore serum levels of miR‐21 and miR‐155 in patients with T2DM complicated CHD and their relationship with lipid metabolism .Methods : A total of 134 T2DM patients treated in our hospital from 2016 to 2017 , were divided into T2DM + CHD group (n＝60) and pure T2DM group (n＝74).Blood glucose and blood lipid levels and serum miR‐21 and miR‐155 levels were measured and were compared between two groups .Results :There were no significant difference in general data , blood pressure , body mass index (BMI) , glycosylated hemo‐globin A1c (HbA1c) , plasma glucose and total cholesterol (TC) between two groups , P＞0. 05 all.Compared with pure T2DM group , there were significant rise in levels of triglyceride (TG) [ (1. 89 ± 0.92) mmol／L vs.(2. 75 ± 1.61) mmol／L] , LDL‐C [ (2.83 ± 0.79) mmol／L vs.(3. 52 ± 1.24) mmol／L] and serum miR‐21 [ (0. 93 ± 0. 15) vs.(1. 86 ± 0.24 )] , and significant reductions in levels of HDL‐C [ (1.35 ± 0. 34 ) mmol／L vs.(0. 94 ± 0.31 ) mmol／L] and serum miR‐155 [ (0. 95 ± 0.19) vs.(0. 27 ± 0. 10)] in T2DM + CHD group , P＝0.001 all.Multiva‐riate Logistic regression analysis indicated that TG , LDL‐C and miR‐21 were independent risk factors for T2DM +CHD (OR＝2. 800～4. 986 , P＜0.05 all) , while HDL‐C and miR‐155 were its independent protective factors (OR＝0.314 , 0.327 , P＜ 0.05 both).Pearson correlation analysis indicated that serum miR‐21 level was significant positively correlated with TG and LDL‐C levels ( r＝0. 415 , 0.506 , P＜0.05 or ＜0. 01) , and serum miR‐155 level was significant inversely correlated with TG and LDL‐C levels ( r＝ －0. 397 ,－0. 526 , P＜0.05 or ＜0. 01 ).Con‐clusion : Serum miR‐21 level was significant positively correlated with TG and LDL‐C levels , but serum miR‐155 level was significant inversely correlated with TG and LDL‐C levels ,

Myelodysplastic syndromes combined with mature plasmacytoid dendritic cells proliferation: report of one case and review of literature / 白血病·淋巴瘤

Objective To investigate the clinical features, diagnosis, treatment and prognosis of myelodysplastic syndromes (MDS) with mature plasmacytoid dendritic cells (PDC) proliferation. Methods The clinical data of one case of MDS with excess blasts (EB)﹣1 with mature PDC proliferation in Air Force Medical Center was retrospectively analyzed, and the literature was reviewed. Results The patient′s physical examination revealed anemia and thrombocytopenia. Bone marrow smears showed 0.064 of myeloblasts and 0.152 of dendritic cells. Immunophenotyping showed two groups of abnormal proliferation cells, namely, myeloblasts and mature PDC. Decitabine treatment was given, and the red blood cells and platelets were infused intermittently. The condition of patient was basically stable. Conclusions MDS with mature PDC proliferation is extremely rare. No special clinical manifestations are found, and the diagnosis is based on bone marrow cytology and immunophenotyping. There is no standard regimen for treatment of MDS with mature PDC proliferation, and the prognosis depends on the progression of MDS.

Application of image guided technique in rhino-orbital related endoscopic surgery / 临床耳鼻咽喉头颈外科杂志

To review retrospectively six cases of rhino-orbital related endoscopic surgeries aided by Fusion electromagnetic system,to explore the indications and clinical value of image guided technique in endonasal endoscopic surgery.Retrospective research methods were used.In this study,six cases of nasal endoscopic sinus surgery using Fusion electromagnetic system were analyzed,including 1 nasal penetrating foreign body,2 optic nerve decompressions,1 orbital apex hemangioma,1 sieve frontal sinus cyst,1 intraorbital mass biopsy.The preparation time of navigation system,the accuracy of intraoperative positioning and surgical coherence,intraoperative and postoperative complications of surgery were recorded.The average preparation time was(8.13 ± 1.858)min.In the navigation,the sinus ostium,orbital cardboard,skull base,optic nerve,internal carotid artery and other important structures can be accurately located in all patients,while registrations had been accurate within 1 mm.Six patients were successfully operated by image guided technique.There was no intracranial or intraorbital complications due to intraoperation error.Image guided technique allows for a truely microinvasive and accurate rhino-orbital related endoscopic surgeries.It requires less preoperative preparation time,has high surgical navigation accuracy,improves the surgical coherence and safety,and reduces the surgical complicationgs.However,as an auxiliary tool,it can not replace the surgeon's anatomical knowledge,surgical training and clinical experience.

Simultaneous Determination of Eight Kinds of Neurotransmitters in Rat Blood Serum by Ultra-high Performance Liquid Chromatograph- Tandem Mass Spectrometry / 分析化学

An ultra-high performance liquid chromatography tandem mass spectrometric ( LC-MS/MS ) method for simultaneous determination of 8 kinds of neurotransmitters (5-HT, GABA, Glu, ACH, NE, DA, 5-HIAA, HVA) in rat serum was developed.The blood samples were extracted by 0.1% formic acid in acetonitrile and separated on a Waters ACQUITY UPLC BEH C18(2.1 mm×100 mm, 1.7 μm) using gradient elution, with the mobile phase consisting of acetonitrile and 0.1% formic acid in water.The samples were then ioniZed with positive electrospray ( ESI+) , and detected under multiple reaction monitoring ( MRM ) mode.As a result, 8 kinds of neurotransmitters were determined accurately in 10 min with a limit of quantitation of 1.8 ng/mL and intra-day and inter-day precisions of ≤9.2% ( n=6 ).This method showed a good linearity in detection of neurotransmitters and the linear correlation coefficients were greater than 0.994.Also the stability, recovery and matrix effect were eligible for the analysis.This method showed high accuracy, sensitivity, strong specificity, good stability, small matrix effect and short time for analysis, and was suitable for the quantitative determination of monoamine, amino acids and acetylcholine neurotransmittes in rat serum.
