Objective:To analyze the current status of frailty in elderly patients undergoing cardiac surgery, explore its risk factors, and establish a predictive model of frailty in order to provide targeted and predictive nursing programs.Methods:A total of 205 cardiac surgery patients admitted to the first affiliated hospital of Xinjiang Medical University from March 2015 to January 2019 were selected as the study subjects. Patients were divided into 2 groups according to whether they were frail: the frailty group ( n=78) and the control group ( n=127). Logistic regression was used to analyze the risk factors that affect the frailty of elderly patients undergoing cardiac surgery. The receiver operating characteristic curve (ROC) was used to evaluate the effectiveness of model X [consisting of body mass index (BMI), Mini-Mental State Examination (MMSE) score, number of diseased patients, and number of drugs] in diagnosing frailty in elderly patients undergoing cardiac surgery. Results:Of the 205 patients, 78 (38.05%) showed frailty. The proportion of high school education level and above, Tinetti Gaitassessment (TGA) score≥24 and MMSE score≥27 in the frailty group was lower than that in the control group, and the proportion of Geriatric Depression Scale-15 (GDS-15) score≥7, the number of diseases≥3 and the number of drugs≥5 in the frailty group was higher than that in the control group ( χ2 value was 9.254-26.061, P<0.05). Logistic regression analysis showed that BMI, MMSE score, number of diseased, and number of medications were independent risk factors for frailty in elderly patients undergoing cardiac surgery ( OR value was 0.032-5.275, P<0.05). The area under the ROC curve, sensitivity and specificity of frailty in elderly cardiac surgery patients assessed by model X were 0.913, 75.61% and 96.77%, respectively. Conclusion:The incidence of frailty is higher in elderly patients undergoing cardiac surgery. Model X can diagnose the frailty of elderly patients undergoing cardiac surgery and help clinical nurses to carry out targeted care.

Objective To explore the relationship between sex hormone-binding globulin (SHBG) of gestational diabetes mellitus ( GDM ) pregnant women with well-controlled glucose and pregnancy outcomes. Methods Two hundred and fifty-one GDM pregnant women of 24 - 28 weeks in Shengjing Hospital of China Medical University were recruited from Mar. 2005 to Mar. 2010. Two hundred and sixteen cases of GDM with well-controlled glucose were defined as glycemic satisfied group, and they were treated by diet therapy ( 169 cases) or insulin therapy (47 cases) . Thirty-five cases with unsatisfied glucose were defined as glycemic unsatisfied group. One hundred and ninety-two healthy pregnant women of 24 - 28 weeks were defined as healthy control group. Serum SHBG and homeostasis model analysis of insulin resistance ( HOMA-IR) at 24 - 28 weeks and above 36 weeks were measured. GDM was diagnosed bytwo-step method according to the National Diabetes Data Group ( NDDG) criteria. The pregnancy outcomes and complications of the three groups were recorded. Results ( 1 ) Comparison of pregnancy outcomes and complications: glycemic satisfied group was less likely to develop hypertensive disorders in pregnancy ( 10. 6% ) , premature birth(8. 3% ) ,large for gestational age ( LGA) (8. 8% ) , neonatal asphyxia(3. 7% ) and neonatal hypoglycemia ( 2. 3% ) compared to glycemic unsatisfied group ( 42. 9% , 34. 3% , 31. 4% , 22. 9% and 11. 4% ,respectively). And the difference was statistically significant (P <0. 05 or P <0. 01). There was no significant difference for incidence of polyhydramnios, pueperal infection, postpartum hemorrhage, neonatal hyperbilirubinemia between the two groups ( P> 0. 05 ) . When compared to healthy control group(7. 3% ,2. 1% ,4. 2% ,2. 1% and 1. 6% ) ,no significant difference was found for incidence of premature birth( 8. 3% ) , pueperal infection ( 3. 2% ) , postpartum hemorrhage (5. 1% ) , neonatal asphyxia (3. 7% )and neonatal hypoglycemia(2. 3% ,P >0. 05). (2) Comparison of results of 24 - 28 weeks and above 36 weeks: serum SHBG of glycemic satisfied group [( 384 ± 88 ) , (457 ± 48 ) nmol/L]was significantly higher than that of glycemic unsatisfied group[(313 ±45) ,(401 ±73) nmol/L];HOMA-IR of glycemic satisfied group (5. 3 ±1.1,5.5 ±1.1) was significantly lower than that of glycemic unsatisfied group (7. 0 ± 1. 3 ,7. 6 ± 1. 7 ; P < 0. 01). Serum SHBG of glycemic satisfied group was significantly lower than that of healthy control group [( 492 ± 95 ) , (565 ± 40 ) nmol/L]; and HOMA-IR of glycemic satisfied group(5. 3 ± 1. 1,5. 5 ± 1. 1) was significantly higher than that of healthy control group (3. 6 ±0. 6,3. 9 ± 0. 5 ;P < 0. 01 ) . FPG of glycemic satisfied group [( 5. 84 ± 0. 28 ) , ( 5. 16 ± 0. 13 ) mmol/L]was significantly lower than that of glycemic unsatisfied group [(6. 13 ± 0. 16 ) , ( 5. 68 ± 1. 14) mmol/L; P < 0. 01]. FINS of glycemic satisfied group [( 20. 4 ± 2. 1 ) , ( 24. 1 ± 4. 2 ) mmol/L]was significantly lower than that of glycemic unsatisfied group [(24. 7 ± 4. 5 ) , ( 29. 9 ± 2. 7 ) mmol/L; P < 0. 01]. ( 3 ) Correlation analysis. Between 24 - 28 weeks, SHBG was negatively correlated with HOMA-IR in the three groups ( r = -0. 952, P <0. 01) ; and SHBG was negatively correlated with HOMA-IR in glycemic satisfied group ( r = -0. 903, P <0. 01). Conclusions Well-controlled glucose can not completely improve maternal and fetal outcomes of GDM pregnant women. High insulin resistance and low serum SHBG can influence pregnancy outcomes.

OBJECTIVE To observe prenatal nicotine exposure (PNE) induced high sensitivity of hypo?thalamic-pituitary-adrenal (HPA) axis in offspring rats which were fed with a high-fat diet, and to explore the mechanism. METHODS Nicotine (2 mg·kg-1 per day) was injected subcutaneously to preg?nant Wistar rats from gestational day (GD) 9 to GD20,and then the young rats were naturally delivered. After weaning, half of the offspring was fed with a high-fat diet until postnatal weeks (PW) 20. The others were exposed to unpredictable chronic stress (UCS) from PW17 to PW20. The pathological changes in the hippocampus were analyzed by HE staining. The blood concentration of adrenocorticotropic hormone (ACTH) and corticosterone (CORT) was detected by RIA kits and ELISA kits, respectively. Meanwhile, real-time PCR was used to detect the mRNA expression of ACTH releasing hormone (CRH), arginine vasopressin (AVP), vesicular glutamate transporter 2 (VGluT2), glutamic acid decarboxylase 65 (GAD65), mineralocorticoid receptor (MR),glucocorticoid receptor (GR) and glutamic acid decarboxylase 67 (GAD67). RESULTS In the normal control group,UCS treatment increased the level of serum ACTH and CORT 1.96 and 3.24 times in female rats,but 1.63 and 3.54 times in male rats. In the PNE group, UCS treatment increased the level of serum ACTH and CORT 3.96 and 5.98 times in female rats, but 3.04 and 5.22 times male rats. PNE increased the mRNA expression of AVP in the female and male rats 2.04 and 1.13 times in UCS treatment control group, and the mRNA expression of hypothalamus CRH and the ratio of VGLuT2/ GAD65 were increased 2.49 and 1.14 times in female rats, respectively. Furthermore, the nicotine group exhibited histological changes to different degrees in the hippocampus and dentate gyrus area of the hippocampus. In the female and male nicotine groups, the mRNA ratio of hippocampal MR/GR decreased by 88.0% and 86.0% in comparison with the normal control group without UCS, and the mRNA expression of GAD67 was enhanced 1.38 and 1.97 times in female and male rats without UCS. In the female UCS treatment nicotine groups, the mRNA expression of GAD67 was increased 2.17 times compared with the UCS treatment control group. CONCLUSION PNE can induce a high sensibility of HPA axis in offspring rats fed with a high-fat diet. The imbalance of hippo?campus MR/GR and the enhanced expression of GAD67 mRNA may be involved.

Objective To detect the DMD gene mutation sites and the regions of breakpoints in Duchenne/Becker muscular dystrophy (DMD/BMD) patients in northern China. Methods Multiplex amplifiable probe hybridization (MLPA) was used to detect the mutation in 59 cases (51 cases with DMD and 8 with BMD) from northern China and dystrophin gene mutations in their parents. Results From northern China and dystrophin gene mutations 59 families found gene deletions in 33 cases of 59 DMD/BMD patients (55.9%), duplications in 6 cases (10. 2%) and point mutation in one case (1.7%). Intron 44 was most frequently affected (n = 13, 33.3%), followed by intron 50 (n = 11, 28.2%) and intron 45 (n=8, 20.5%). The novel mutations were identified, in two patients including two independent duplications carried by patient D1 149 and a point mutation [5208del(A)] carried by patient D1 65, which were not included in Leiden database. In addition, an exon 22 deletion was found in one patient, which was the first reported case in Chinese patients. Conclusions Deletions are mostly located in the hotspot between exon 45 and 50. Duplications mostly occurred in the 5' end of the gene. Intron 44 is the most frequently affected breakpoint in northern Chinese population.

[Objective]To explore the relationship between peripheral arterial disease(PAD)and diabetic retinopathy(DR)in type 2 diabetes patients.[Methods]A total of 99 patients diagnosed with PAD were classified into grade 1-3 by their total scores of peripheral arterial stenosis assessed by color doppler ultrasound examinations,where the degree of stenosis 30% ~ 49% scored 0, 50%~99%scored 1,lumen occlusion(i.e. degree of stenosis 100%)scored 2,and therefore the total score 0-2 was categorized into Grade 1 ,3~4 into Grade 2 ,5~12 into Grade 3. The bilateral anterior tibial artery ,posterior tibial artery and dorsalis pedis artery of these patients were analyzed. The presence of diabetic retinopathy(DR)was graded from retinal photographs using a standard protocol.[Results]Among 99 cases of type 2 diabetic patients with peripheral arterial disease ,58.6%of them were male with average age of 67.3 ± 7.9 years old. Patients of Grade 1,Grade2,Grade 3 lesion accounted for 45.4%,30.3%,24.2%,respectively. Age, gender,smoking history,SBP,DBP,BMI,FBG,TC,TG,LDL-C,HDL-C,HbA1C among 3 groups were not statistically signifi-cant. The associations of DM duration and HbA1C value were significantly larger in DR than in PAD. The proportion of DR patients increased with the severity degree of PAD(p for trend=0.004). Degree of stenosis Grade 2 and Grade 3 could be predictive for DR.[Conclusions]DR is associated with the severity degree of PAD in type 2 diabetes patients as evaluated by duplex ultrasonography.Degree of stenosis Grade 2 and 3 could be used for screening or finding DR. Strategies for optimum treatment and early prevention are needed.

Objective:To evaluate the effect of exercise on the sleep quality of elderly persons experiencing a sleep disorder so as to provide an evidentiary basis for future studies.Methods:Reports of randomized and controlled trials of the effects of exercise on sleep quality among elderly persons with sleep disorders were extracted from the Cochrane library, PubMed, EMbase, the Web of Science, CNKI and other databases. Reports from the database′s inception to August 28, 2019 were retrieved. All were screened applying inclusion and exclusion criteria, and their methodological quality was evaluated using the Cochrane bias risk tool. The combined effect was analyzed using version 5.0 of the ReMan software.Results:Nine reports covering 928 patients were identified. Meta-analysis showed that compared with the control group, exercise could significantly improve the overall sleep quality of elderly patients with sleep disorders in terms of sleep score, subjective sleep quality, sleep latency, sleep duration, sleep efficiency, degree of sleep disturbance, sleep medication use, and daytime functioning.Conclusion:Exercise can improve the overall sleep quality of patients with a sleep disorder, shortening the sleep latency, improving sleep efficiency, reducing the use of sleep drugs, and improving their daytime functioning. However, it has less effect on subjective evaluations of sleep quality and sleep disorder.

Objective:
To analyze the association between tea drinking during pregnancy and the risk of preterm delivery and abortion,so as to provide basis for prevention of preterm delivery and abortion.
Methods:
The databases of CNKI,Wanfang,VIP,CBMdisc,PubMed and Web of Science were searched for cohort studies and case-control studies into the association between tea consumption during pregnancy and preterm delivery or abortion until June 30 th,2019. Relative risk(RR)or odds ratio(OR)were used as indicators for the meta-analysis.
Results:
A total of 1 099 articles were retrieved,14 of them were included in the quantitative study,including 9 cohort studies with 18 295 exposed and 71 890 unexposed individuals and 5 case-control studies with 1 351 cases and 3 059 controls. There was no statistically significant association between tea drinking during pregnancy and preterm birth or abortion(OR/RR=1.08,95%CI:0.99-1.18). The linear regression model of random effect showed that with the increase of tea consumption during pregnancy,the risk of premature delivery and abortion did not change significantly(OR/RR=1.05,95%CI:0.99-1.11). There was no publication bias found in Begg's test and Egger's test.
Conclusion
Drinking tea during pregnancy is not associated with preterm delivery and abortion.
