Objective To investigate the ultrasonography,high-risk factors and pregnancy outcomes related to pernicious placenta previa(PPP)and neonatal asphyxia.Methods The clinical data of 144 pregnant women with PPP from Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology from May 2016 to July 2020 were retrospectively analyzed.Depending on the neonatal condition,they were divided into non-asphyxia group(n=91)and asphyxia group(n=53).Mainly by prenatal ultrasound ex-amination and intraoperative diagnosis,the high-risk factors of neonatal asphyxia were analyzed with univariate and multivariate Logistic regression analysis,and the neonatal outcomes were compared between the two groups.Results Compared with the non-asphyxia group,the incidence of placenta dominated by anterior wall,complete placenta previa,premature delivery,polyhydramnios and placenta percreta were higher in the asphyxia group,and the differences were statistically significant(P＜0.05).Multivariate Logistic regression analysis showed that placenta dominated by anterior wall,premature delivery,polyhydramnios and placenta percreta were independent risk factors for neonatal asphyxia(P＜0.05,OR＞1).Compared with the non-asphyxia group,the incidence of neonatal admission was higher with lower gestational age and birth weight in the asphyxia group(P＜0.05).Conclusion The risk factors related to PPP and neonatal asphyxia are placenta dominated by anterior wall,premature delivery,polyhydramnios and placenta percreta.Pregnancy outcomes related to PPP and neonatal asphyxia are worse.

Objective To investigate the relationship between appendicular skeletal muscle composition(muscle mass and muscle index)and glycosylated hemoglobin A1c(HbA1c)level in type 2 diabetes mellitus(T2DM)patients.Methods A total of 459 adult T2DM patients hospitalized in the Department of Endocrinology,Tangdu Hospital of Air Force Medical University from April 2021 to June 2022 were selected as the research objects.Bioelectrical impedance analysis was used to evaluate the body composition of the patients.The patients were divided into two groups according to HbA1c level:standard glycation group(HbA1c≤7.0%,n=145)and unqualified glycation group(HbA1c>7.0%,n=314).The two groups'general data,biochemical indexes,muscle content,fat content and other body composition were analyzed.Spearman correlation analysis and multiple logistic regression analysis were used to analyze the relationship between body composition and glycemic control in type 2 diabetic patients.Results The appendicular skeletal muscle mass and its index(ASMI)of the patients in the standard glycation group were better than those in the unqualified glycation group(P<0.05).However,there were no significant differences in gender,history of antidiabetic drugs and body fat(body fat content,limb fat content and visceral fat content)between the two groups(P>0.05).Spearman correlation analysis showed that appendicular skeletal muscle mass and its index were negatively correlated with HbA1c(r=-0.158,P=0.001;r=-0.187,P<0.001).Logistic regression analysis showed that upper limb skeletal muscle mass(OR=3.570,95%CI 2.293-5.559)and lower limb skeletal muscle mass(OR=1.297,95%CI 1.146-1.468)were independent protective factors for achieving glycation standard in HbA1c group.Conclusions The skeletal muscle mass of limbs is a protective factor for reaching the standard of HbA1c.With the increase of skeletal muscle mass of limbs,the level of HbA1c gradually decreases.Among them,the increase of upper limb muscle mass has a stronger correlation with reaching the standard of HbA1c.

In the outbreak of COVID-19,triage procedures based on epidemiology were implemented in a local hospital in Changsha to control the transmission of SARS-CoV-2 and avoid healthcare-associated infection.This re-trospective study analyzed the data collected during the triage period and found that COVID-19 patients were en-riched 7 folds into the Section A designated for patients with obvious epidemiological history.On the other side,nearly triple amounts of visits were received at the Section B for patients without obvious epidemiological history.8 COVID-19 cases were spotted out of 247 suspected patients.More than 50％of the suspected patients were submi-tted to multiple rounds of nucleic acid analysis for SARS-CoV-2 infection.Of the 239 patients who were diagnosed as negative of the virus infection,188 were successfully revisited and none was reported as COVID-19 case.Of the 8 COVID-19 patients,3 were confirmed only after multiple rounds of nucleic acid analysis.Besides comorbidities,delayed sharing of epidemiological history added complexity to the diagnosis in practice.The triaging experience and strategy will be helpful for the control of infectious diseases in the future.

BackgroundPerinatal depression seriously affects the physical and mental health of pregnant women， such as affecting their role transition， identity， and family relationships， etc. In severe case， it can even lead to suicidal behavior， causing a heavy burden on pregnant women and their families. A hierarchical management model centered on pregnant women， involving collaboration of families， communities， and hospitals， facilitates comprehensive and dynamic management of perinatal depression. ObjectiveTo evaluate the application effect of "Internet +" hospital-community-family trinity linkage management model on perinatal depression in pregnant women， in order to provide a reference for the clinical intervention. Methods80 pregnant women who established medical records from the Department of Obstetrics and Gynecology of Mianyang Third People's Hospital from January to December 2022， with Edinburgh Postnatal Depression Scale （EPDS） score>9， were selected as the research objects. According to the random number table method， they were divided into a study group and a control group， each group consisting of 40 cases. Both groups received routine nursing intervention in the pregnant women's school of obstetrics and gynecology outpatient department before delivery， and in the study room of the department of obstetrics and gynecology after being admitted to the hospital for delivery. After discharge， they received routine follow-up until 42 days postpartum. The study group received the "Internet +" hospital-community-family ternary linkage management on the basis. EPDS， Pittsburgh Sleep Quality Index （PSQI）， Generic Quality of Life Inventory （GQOLI-74） and Nursing Satisfaction questionnaire were assessed before intervention and 42 days postpartum. ResultsAfter intervention， the EPDS score and PSQI score of the study group were lower than those of the control group （F=42.823， 60.453， P<0.05）， GQOLI-74 score and nursing satisfaction were higher than those of the control group （F=198.902， χ²=5.165， P<0.05） . Conclusion"Internet +" hospital-community-family trinity linkage management model may help to improve the severity of perinatal depression symptoms， improve the quality of sleep and life， and increase the satisfaction of pregnant women.［Funded by Mianyang Health Scientific Research Commission Project （number， 202134）］

Objective:To study influence of Status-Background-Assessment-Recommendation(SBAR)communi-cation mode intervention on patients with heart failure(HF).Methods:According to intervention method,a total of 187 HF patients treated in our hospital were divided into routine intervention group(n=96,received routine in-tervention based on routine treatment)and SBAR group(n=91,received SBAR communication mode intervention based on routine treatment).Both groups were intervened for six months.General clinical data,LVEF,left ven-tricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV),scores of Morisky medi-cation compliance scale and the medical outcomes study 36-item short-form heath survey(SF-36),patients'satis-faction and incidence rate of major adverse cardiovascular events(MACE)within six-month follow-up were com-pared between two groups.Results:Compared with routine intervention group,after intervention,there were sig-nificant rise in LVEF[(53.44±2.11)%vs.(57.72±1.80)%],scores of Morisky medication compliance scale[(2.00±0.77)scores vs.(3.63±1.07)scores]and SF-36[(68.83±7.62)scores vs.(76.81±9.68)scores],and significant reductions in LVEDV[(132.63±5.59)ml vs.(119.15±6.89)ml]and LVESV[(64.36±5.82)ml vs.(56.62±4.21)ml]in SBAR group(P=0.001 all).Patients'satisfaction of SBAR group was significantly higher than that of routine intervention group(89.01%vs.73.96%,χ2=6.958,P=0.008),and incidence rate MACE during follow-up was significantly lower than the latter(5.49%vs.15.63%,LogRankχ2=5.043,P= 0.025).Conclusion:SBAR communication mode intervention can significantly improve heart function,medication compliance and quality of life in patients with heart failure,with high patients'satisfaction.

Objective To investigate the value of ¹⁸F-FDG PET/CT metabolic parameters and metabolic heterogeneity for predicting the expression of human epidermal growth factor receptor 2 (HER2) in patients with gastric cancer. Methods A total of 45 patients with gastric cancer confirmed by surgical pathology between September 2016 and May 2021 were enrolled in this study.All the patients underwent ¹⁸F-FDG PET/CT examination before surgery.The maximum standardized uptake value (SUVmax),metabolic tumor volume (MTV),and total lesion glycolysis (TLG) of primary gastric cancer were measured,and the linear regression slope of MTV corresponding to different SUVmax thresholds (40% SUVmax and 80% SUVmax) was calculated.The absolute value of the slope was deemed to represent the metabolic heterogeneity of primary gastric cancer,termed the heterogeneity index (HI).Univariate and multivariate Logistic regression analyses were conducted to evaluate the correlations of ¹⁸F-FDG PET/CT metabolic parameters and HI with HER2 expression. Results The 45 patients included 10 with positive HER2 expression and 35 with negative result.The MTV (P=0.043) and HI (P=0.048) were lower in the patients with positive HER2 expression than in the patients with negative HER2 expression.The MTV and HI had the optimal thresholds of 12.10 cm³ and 3.71,respectively,which respectively showed the accuracy of 62.2% and 57.8% for predicting HER2 expression.The univariate Logistic regression showed that the tumor differentiation degree,MTV,and HI were correlated with HER2 expression,while the multivariate Logistic regression showed that only the tumor differentiation degree (OR=20.130,95%CI=1.843-219.860,P=0.014) was an independent predictor for HER2 expression.A further stratified analysis of the tumor differentiation degree showed that HER2 expression only varied among different MTV threshold groups in patients with moderately/well differentiated gastric cancer (P=0.031). Conclusions MTV and HI were associated with HER2 expression in gastric cancer,whereas neither played an independent predictive role.Therefore,these factors should be combined with clinicopathological characteristics of patients to jointly guide treatment decisions.

Objective: To understand the epidemiological characteristics of bacillary dysentery with multiple-onset in Henan province from 2005 to 2020. Methods: The reported cases of bacillary dysentery (including confirmed cases and clinically diagnosed cases) in Henan Province from January 2005 to December 2020 were collected through China's National Disease Supervision Information Management System. The main information included gender, age, home address, date of onset and date of diagnosis. The interval between two episodes of the same case was more than 15 days, which was judged as two episodes. The incidence characteristics of bacillary dysentery patients with two or more cases in Henan Province from 2005 to 2020 were analyzed, and the regional distribution map of cases was drawn using ArcGIS software. Results: From 2005 to 2020, a total of 250 430 cases of bacillary dysentery were reported in Henan Province, with a cumulative incidence rate of 228.66/100 000. There were 2 342 cases with two or more attacks. The incidence of recurrent cases of bacillary dysentery increased year by year (χ²_trend=2 932.28, P<0.001). There was no significant difference in the incidence of two or more cases of different sexes (χ²=0.39, P=0.540). There was significant difference in the incidence among different age groups (χ²=438.40, P<0.001). The incidence of two or more cases in the 60-69 age group was relatively high (1.70%). The shortest time interval between the onset of the disease was 16 days, and the longest was 5 579 days, with M (Q₁, Q₃) about 428 (237, 843) days. Compared with healthy people, those with a history of bacterial diseases had a higher risk of developing bacillary dysentery (RR: 4.12, 95%CI: 3.95‒4.29). Conclusion: The proportion of patients with multiple-onset shows an increasing trend, and there is an age difference.

Volatile oil of traditional Chinese medicine （VOTCM） is a plant volatile component obtained through distillation or supercritical fluid extraction. The volatile oil is rich in terpenes and phenylpropanoids， with many different effect. It is not only widely used in healthcare products， but also has a variety of pharmacological effect， such as analgesia， antioxidant， antibacterial， anti-inflammatory， anti-tumor effect. Malignant tumor is an important threat to human health. At present， the drugs commonly used in clinical treatment of tumors are expensive with certain toxic and side effect. Although new treatment technologies are also being promoted step by step， they have higher treatment costs than traditional chemotherapies， and the long-term efficacy remained to be further confirmed. The effect of volatile oil of traditional Chinese medicine（TCM） on cancer is receiving more and more attention. In particular， it has a significant inhibitory effect on lung， liver， colon， and stomach cancer. Specifically， it can not only reduce the side effect of chemotherapy drugs， but also effectively prolong or stop the tumor recurrence， with special effects in treatment and adjuvant treatment. At the same time， various anti-tumor mechanisms of volatile oils have been discovered， such as inducing tumor cell apoptosis， inhibiting tumor blood vessel formation， inhibiting tumor cell proliferation， inducing tumor cell differentiation， interfering with multidrug resistance， and regulating the body's immune function. However， there are still some problems in the basic research， achievement transformation， and product development of volatile oil of TCM， which restricts its clinical and daily application. This paper summarizes the antitumor mechanism of volatile oil of TCM by consulting relevant domestic and foreign literatures， analyzes the current situation of volatile oils， and proposes improvement directions for its problems and development， in the expectation of laying the foundation for the research of volatile oil of TCM in anti-tumor research.
