The intervention and prevention of perioperative hypothermia is not only reflected in the technical level, but also reveals the important role of humanistic care in the whole intervention work. If perioperative patients have hypothermia, it is likely to cause a series of complications such as postoperative shivering, which seriously threatens the life safety of patients. Prevention and intervention was based on a comprehensive understanding of the causes and hazards of hypothermia, especially the impact on the lives of the elderly. Effective supervision was implemented in the whole process of operation, such as dynamic monitoring of vital signs including body temperature, followed by room temperature regulation, body temperature protection and preoperative and postoperative psychological nursing. At this time, the sense of responsibility, good humanistic care of medical staff are of positive significance to effectively prevent and reduce the probability of perioperative hypothermia and accelerate the postoperative rehabilitation of patients.

Background There is a lack of research evidence on the association between sugar-sweetened beverage (SSB) consumption and gestational diabetes mellitus (GDM) in China. Objective To explore the association between frequency of SSB consumption before pregnancy and risk of GDM in pregnant women in Shaanxi Province, and to provide a scientific basis for targeted interventions to control maternal blood glucose. Methods The recruitment to the China Birth Cohort study started in October 2020. Pregnant women at 6-16 weeks who had their first prenatal examination at five hospitals in Shaanxi Province were recruited. A maternal health questionnaire was used to collect basic information about pregnant women. A semi-quantitative food frequency questionnaire was used to collect the consumption of carbonated beverages, fruit and vegetable juice beverages, coffee beverages, and milk tea beverages in one year before pregnancy, which were summed to obtain the SSB consumption. Pregnant women were divided into three groups according to SSB consumption, namely <1 serving·week⁻¹, 1-4 servings·week⁻¹, and ≥5 servings·week⁻¹. GDM was confirmed by oral glucose tolerance test (OGTT) between 24-28 weeks of gestation. A binary logistic regression model was applied to explore the association between SSB consumption and risk of GDM. Multiple linear regression was applied to investigate the associations between SSB consumption (per 1-serving·d⁻¹ increase) and OGTT fasting plasma glucose, 1-hour glucose, and 2-hour glucose. Results A total of 3811 pregnant women were finally enrolled in this study, of which 752 developed GDM, with an incidence rate of 19.7%. The incidence rates of GDM in pregnant women with SSB consumption frequency of <1 serving·week⁻¹, 1-4 servings·week⁻¹, and ≥5 servings·week⁻¹ were 18.0%, 21.1%, and 26.8%, respectively. After adjusting for maternal age, pre-pregnancy body mass index (BMI), education, number of children born, family history of diabetes, smoking, alcohol consumption, physical activity level, and total energy intake, the risk of GDM increased by 26% (OR=1.26, 95%CI: 1.05, 1.50) in the 1-4 servings·week⁻¹ group and by 76% (OR=1.76, 95%CI: 1.31, 2.38) in the ≥5 servings·week⁻¹ group compared to the <1 serving·week⁻¹ SSB consumption group, respectively. Further stratified analysis revealed no interaction effect (P_interaction>0.05) between SSB consumption and maternal age, pre-pregnancy BMI, or first labor or not. For each additional SSB consumption per day, the risk of GDM increased by 94% (OR=1.94, 95%CI: 1.37, 2.75); and the maternal OGTT 1-hour glucose and 2-hour glucose increased by 0.33 mmol·L⁻¹ and 0.18 mmol·L⁻¹, respectively (P<0.05), and no significant increase in fasting plasma glucose was found (P>0.05). Conclusion Higher SSB consumption before pregnancy increases the risk of GDM in pregnant women.

Objective:To investigate the efficacy and safety of geritinib in the treatment of acute myeloid leukemia (AML) with FLT3 mutation.Methods:The clinical data of 5 AML patients with FLT3 mutation who were diagnosed in the University of Hong Kong-Shenzhen Hospital, Shenzhen People's Hospital, Shenzhen Second People's Hospital, Shenzhen University General Hospital from March 2020 to April 2021 were retrospectively analyzed. Relapsed patients concurrently received two- or three-drug chemotherapy combined with geritinib. Blood routine was checked once a week; liver function and renal function were checked once every 2 weeks during treatment. Bone marrow puncture was performed once every 1 to 3 months to monitor the bone marrow morphology, minimal residual disease (MRD) and FLT3 mutation expression levels. The efficacy, side effects, overall survival of these patients were analyzed after treatment with geritinib.Results:The white blood cell was increased in all the 5 patients at the initial diagnosis. FLT3 mutations analysis showed FLT3-internal tandem duplication (ITD) (3 cases) and FLT-3 tyrosine-kinase domain (TKD) (2 cases). Among 5 patients, 1 patient was relapse-free with maintenance therapy of oral geritinib after hematological stem cell transplantation (HSCT) for 60 days; among other 4 relapsed and refractory patients, 1 female patient after pregnancy relapsed after transplantation and then achieved complete remission followed by the maintenance therapy with geritinib after oral geritinib, 1 16-year-old patient achieved treatment outcome close to the complete remission after treatment with geritinib, 1 patient achieved complete remission after treatment with geritinib, and then underwent haplo-HSCT followed by the maintenance therapy with geritinib and the other 1 relapsed patient achieved complete remission after treatment with geritinib. After transplantation, 3 patients receiving maintenance treatment of geritinib did not relapse. The main side effects included anemia, decreased neutrophil count, rash, and increased aminotransferase. The median follow-up time of 5 patients was 15 months (6-20 months). All 5 cases survived until the last follow-up in November 2021 and 4 patients were disease-free.Conclusions:Relapsed and refractory AML patients with FLT3 mutation can achieve complete remission after treatment with geritinib and get a chance for transplantation. Geritinib may reduce the risk of recurrence after transplantation and improve survival rate. No serious side effects occur in geritinib treatment.

Objective:To explore the effect of empowerment education in patients with coronary heart disease after percutaneous coronary intervention (PCI) .Methods:From June 2020 to July 2021, convenience sampling was used to select 90 patients with coronary heart disease who received PCI in the Department of Cardiology of Qinhuai Medical District, Eastern Theater Command General Hospital as the research object. The 45 patients admitted from June to December 2020 were set as the control group, and the 45 patients admitted from January to July 2021 were set as the observation group. The control group received routine health education, and the observation group was given empowerment education on this basis. The physical activity level and aerobic exercise endurance of the two groups of patients were compared.Results:Repeated measures analysis of variance showed that there were between-group, time and interaction effects in the 6-minute walking distance between the two groups before intervention, one month and three months after intervention, and the differences were statistically significant ( P<0.05) . The physical activity levels of patients in the observation group were higher than those in the control group after one and three months of intervention, and the differences were statistically significant ( P<0.05) . Conclusions:Empowerment education can improve physical activity level and aerobic exercise endurance in patients with coronary heart disease after PCI.

Objective:To investigate the immediate and lasting effects of enhanced external counterpulsation(EECP)on blood pressure in elderly patients with hypertension.Methods:In this real-world prospective non-randomized controlled study, the elderly hypertensive patients who were newly diagnosed as hypertension or had poor blood pressure control in the Geriatrics Department of Shandong University Qilu Hospital from May 2019 to December 2019, were enrolled as EECP group, and those with systolic blood pressure(SBP)≥180mmHg(1mmHg=0.133 kPa)or had contraindications for EECP treatment were excluded from EECP group(28 cases). Based on the 1∶1 ratio being consistent with the tendency score-matching method, patients' blood pressure was matched at 3 d before the start of the EECP treatment course, with other matched data of baseline data, coexisting disease, cardiovascular medication were choosed as control group(n=28). The EECP group received an additional 36 hours of EECP treatment(6 times/week, 1 hour/time)including lifestyle improvement and anti-hypertensive drugs.The patient's supine blood pressure was collected 3 minutes before each EECP treatment(baseline), 30 minutes during treatment, and 3 minutes after treatment.In the EECP group, family self-measured blood pressure was collected 3 days before the start of the 6-week treatment course(0w), the 6th week(6w)of the treatment course, and the 2nd week(+ 2w), 4th week(+ 4w)and 12th week(+ 12w)after the end of the treatment course, respectively.And the data of control group were collected at the same time point mentioned above.Results:Compared with baseline, the average immediate SBP of elderly hypertensive patients at the 30th minute of EECP treatment was decreased by(5.5±13.6)mmHg( P<0.001), and the average immediate diabolic blood pressure(DBP)was decreased by(1.1±7.5)mmHg( P<0.001). When the baseline SBP was between 160 and 169 mmHg, the probability of a further increase in SBP during treatment was 2.2%(2/89 cases), and when the baseline SBP was between 170 and 179 mmHg, the probability of a further increase in SBP during treatment was 0%(0/57). At 6 weeks, the decrease in SBP was significantly greater in the EECP group than in the control group[(-17.0±8.7)mmHg vs.(-10.5±7.3)mmHg, P<0.01], and the difference continued to + 2w[(-15.5±6.6)mmHg vs.(-10.6±2.5)mmHg, P<0.01]and + 4w[(-13.3±5.4)mmHg vs.(-10.7±2.1)mmHg, P<0.05]. At + 12w, the blood pressure drop was still greater in EECP group than in the control group, but it did not achieve statistically significant differences.Smoking history, history of diabetes, family history of hypertension, and improvement of comorbidities were the key factors that affect the continuous anti-hypertensive effect of EECP. Conclusions:EECP treatment has an immediate effect on lowering blood pressure in elderly hypertensive patients.A 6-week course of EECP treatment has a sustained effect on lowering blood pressure, and the effect can last from 4 to 12 weeks after the end of the course of treatment.

Objective To investigate the comprehensive improvement of multi-system diseases in elderly patients treated with enhanced external counterpulsation(EECP).Methods Clinical data of an elderly patient with multiple systemic diseases were collected and analyzed.The therapeutic effect of EECP was assessed and EECP-related literatures were reviewed.Results The 62-year-old male patient was diagnosed with coronary atherosclerotic heart disease,unstable angina,New York Heart Association(NYHA)functional class Ⅱ,hypertension(grade 3,very high risk),type 2 diabetes,acute cerebral infarction (recovery period)and benign prostatic hyperplasia.After two courses of EECP treatment,angina in the patient was significantly relieved,cardiac systolic and diastolic function was improved,activity tolerance was increased and the corresponding dosage of therapeutic drugs was reduced.In addition,the patient's blood pressure and blood glucose levels were decreased after versus before treatment and the retinal superficial blood flow was enhanced in both eyes assessed by optical coherence tomography.The frequency and volume of nocturia were reduced.The symptoms of numbness on the left side were improved.Conclusions EECP treatment has shown significant therapeutic effects on multi-system diseases in the elderly patient.EECP is safe,effective and simple and has a broad application prospect in geriatrics.

Objective To study the protective effect of trimetazidine pretreatment on myocardial I/R in a rat I/R model and its mechanism.Methods One hundred and twenty SD rats were divided into control group,I/R group,HSP70 inhibitor group,trimetazidine treatment group and combined treatment group (24 in each group).The rats in each group were further divided into 30 min reperfusion group,4 h reperfusion group and 8 h reperfusion group (8 in each group).Their HSP70-positive myocardial cells were calculated,their serum CK,CK-MB,MDA,SOD levels and their myocardial infarction size were measured.Results The serum CK and CK-MB levels were significantly higher in I/R group,HSP70 inhibitor group,trimetazidine treatment group and combined treatment group than in control group and were significantly lower in trimetazidine treatment group than in combined treatment group and I/R group after reperfusion for 4 and 8 h (P＜0.01).The serum levels of HSP70 and SOD were significantly higher,the MDA levels were significantly lower in trimetazidine treatment group than in combined treatment group and I/R group after reperfusion for 30 min,4 and 8 h (P＜0.01).The infraction size was significantly smaller in trimetazidine treatment group than in combined treatment group and I/R group after reperfusion for 4 and 8 h (P＜0.05).Conclusion Trimetazidine can increase the serum HSP70 level in myocardial cells,reduce the infarction size,and protect the myocardium against I/R in rats.

Objective To report a pedigree with tyrosinemia type Ⅱ,and to analyze its causative mutations.Methods Clinical data were obtained from a 10-year-old male proband with tyrosinemia type Ⅱ,and analyzed retrospectively.Blood and urine samples were collected from 19 persons in 3 generations of the pedigree,and the amino acid level was detected in these samples.Genomic DNA was extracted from all of the 19 family members,and mutations in the tyrosine aminotransferase (TAT) gene were detected.Results The patient developed photophobia at 2 months after birth,and the symptom was gradually aggravated after that.At the age of 6 years,ocular pain and photophobia occurred.At the age of 8 years,linear keratotic plaques occurred on his fingertips and soles of both feet,with obvious tenderness.Ophthalmic examination showed no obvious abnormalities in corneal staining or ocular fundus.Skin examination showed multiple linear keratotic plaques on the fingers and soles of both feet.The serum tyrosine level was 825.64 μmol/L,and the level of p-hydroxyphenyllactic acid in urine was 161.4 μmol/L.Genetic testing showed 2 novel mutations,including c.236G ＞ A at position 236 in exon 2 of the TAT gene causing the substitution of glycine by glutamic acid (p.Gly79Glu),and c.1141G ＞ T at position 1141 in exon 10 of the TAT gene leading to the formation of a premature termination codon instead of glutamic acid (p.Glu381*).The proband was the only patient in the family.Some members in the patrilineal family carried the mutation c.1141G ＞ T (p.Glu381*),and some in the maternal family carried the mutation c.236G ＞ A (p.Gly79Glu).Conclusion This is the first case of tyrosinemia type Ⅱ reported in the domestic population,and 2 novel heterozygous mutations were identified in the TAT gene,which may lead to the occurrence of tyrosinemia type Ⅱ in the patient.

Objective To investigate the mutations of BRCA genes in sporadic high grade serous ovarian cancer (HGSOC) and study its clinical significance. Methods Sixty-eight patients between January 2015 and January 2016 from the Affiliated Cancer Hospital of Zhengzhou University were collected who were based on pathological diagnosis of ovarian cancer and had no reported family history, and all patients firstly hospitalized were untreated in other hospitals before. (1)The BRCA genes were detected by next-generation sequencing (NGS) method. (2)The serum tumor markers included carcinoembryonic antigen (CEA), CA125, CA199, and human epididymis protein 4 (HE4) were detected by the chemiluminescence methods, and their correlation was analyzed by Pearson linear correlation. Descriptive statistics and comparisons were performed using two-tailed t-tests, Pearson′s chi square test, Fisher′s exact tests or logistic regression analysis as appropriate to research the clinicopathologic features associated with BRCA mutations, including age, International Federation of Gynecology and Obstetrics(FIGO)stage, platinum-based chemotherapy sensitivity, distant metastases, serum tumor markers (STM). Results (1) Fifteen cases (22%, 15/68) BRCA mutations were identified (BRCA1: 11 cases; BRCA2: 4 cases), and four novel mutations were observed. (2) The levels of CEA, CA199, and HE4 were lower in BRCA mutations compared to that in control group, while no significant differences were found (P>0.05), but the level of CA125 was much higher in BRCA mutation group than that in controls (t=-3.536,P=0.003). Further linear regression analysis found that there was a significant linear correlation between CA125 and HE4 group (r=0.494,P<0.01), and the same correlation as CEA and CA199 group (r=0.897,P<0.01). (3) Single factor analysis showed that no significant differences were observed in onset age, FIGO stage, distant metastasis, and STM between BRCA+and BRCA- group (P>0.05), while significant differences were found in CA125 and sensitivity to platinum-based chemotherapy between the patients with BRCA mutation and wild type (P<0.05). The multiple factors analysis showed that the high level of CA125 was a independent risk factor of BRCA mutations in sporadic HGSOC (P=0.007). Conclusion The combination of CA125 with BRCA have great clinical significance, the mutation of BRCA gene could guild the clinical chemotherapy regiments.
