Objective To investigate relationship between obstructive sleep apnea hypoventilation syndrome(OSAHS) and hypertension.Methods Questionnaire survey was conducted among 1573 local permanent residents in Guangzhou during March and June 2006 to understand prevalence of hypertension and snoring,and polysomnography monitoring was performed for 347 of them with moderate and severe snoring to estimate prevalence of OSAHS.Risk factors for hypertension was screened with multivariate logistic regression analysis.Results In total,1547 copies of valid questionnaires were collected,and 184 cases (11.9%) of hypertension were found with a prevalence of 10Department of Endocrinology,Shanxi Provincial People's Hospital,Taiyuan 030012,China 0%,49 of diabetes with a prevalence of 2.7%,and 212 of dyslipidemia with a prevalence of 10.4%.Prevalence of OSAHS was found in 34 of them (2.2% ) with Epworth sleepiness scale (ESS) score equal to or greater than nine.Prevalence of hypertension in OSAHS group was 32.5%,much higher than that in non-snoring group (8.3% ) and snoring group ( 17.1% ).Results of logistic regression analysis showed that age,gender,OSAHS,diabetes and dyslipidemia all were high-risk factors for hypertension,with OSAHS ranking the third.Conclusion OSAHS is one of high-risk factors for hypertension.

Objective To discuss the effect of the combination detection of cardiac troponin I (cTnI) and homocysteine(Hcy) for increasing the diagnosis and treatment offects of non-ST elevation myocardial infarction (NSTEMI) .Methods The levels of cTnI and Hcy were detected in 47 patients with NSTEMI(NSTEMI group) before and after therapy and 63 healthy individuals(control group) .The detection results were performed the statistical analysis for verifying their value to judge the diagnostic and treatment effect of NSTEMI .Results The levels of cTnI and Hcy were (2 .37 ± 0 .65)ng/mL and(19 .23 ± 2 .94)μmol/L in the NSTEMI group ,which were significantly higher than(0 .33 ± 0 .14)ng/mL and(10 .62 ± 3 .27)μmol/L in the control group ,the differences showing statistical significance (P< 0 .05);the sensitivities of single cTnI and Hcy were 95 .74% and 85 .11% respectively ,and their specificities were 85 .71% and 90 .48% respectively ;the sensitivity and sepecificity of cTnI and Hcy combination detection were risen to 97 .87% and 98 .41% respectively ;after therapy ,the cTnI and Hcy levels in the NSTEMI group were significantly lowered and close to the normal levels .Conclusion The combination detection of cTnI and Hcy can not only be used for the diagno-sis of NSTEMI ,but also has the important significance to the judgment of the therapeutical effect of NSTEMI .

Objective: To explore the clinical efficacy of Xiaoshuan enteric-coated capsule (XSECC) in treating cerebral infarction and its potential mechanism of action. Methods: Patients with acute ischemic stroke (AIS) of the qi deficiency and blood stasis type were randomly assigned to the control and observation groups. They were evaluated using the National Institutes of Health Stroke Scale (NIHSS), Activities of Daily Living (ADL), Hachinskilnchemic Scale (HIS), Barthel Index (BI), clinical efficacy scores, and TCM syndrome scores on days 0, 14, 30, and 90. Furthermore, VEGF and BDNF levels were measured on days 30 and 90. Finally, we analyzed the changes in each scale score and vascular neurological factor in both groups. Results: After 14 days of treatment, the difference values in NIHSS, ADL, and BI were higher, and TCM syndrome and clinical efficacy scores were increased in the observation group compared with those of the control group (all P < .05). After 30 days, the NIHSS, ADL, HIS, and TCM syndrome scores were decreased compared with those of the control group, while BI and clinical efficacy scores were increased (all P < .05). After 90 days, the difference value in ADL was higher, and TCM syndrome score was increased in the observation group compared with that of the control group (P = .047, P = .005, respectively). The levels of VEGF and BDNF were higher in the observation group than in the control group on days 14, 30, and 90 (all P < .05). VEGF and BDNF levels on day 0 were associated with prognosis of patients with AIS; therefore, they have a predictive value for the prognosis of acute cerebral infarction. Conclusions XSECC therapy can improve clinical outcomes in patients with acute and recurrent cerebral infarctions. Its mechanism of action may be associated with the secretion of VEGF and BDNF.

Objective To determine the composition of abnormal red cell membrane skeletin. Methods By sodium dodecyl sulphate polyacrylamide gel electrophoresis of ghostcorpuscles, we quantified the amount of protein by densitometric evaluation.Results The results showed that in β-thalassernia, the amount of spectrin, 4.5 protein and globin significantly increased compared with the controls (26.05 + 1.46, 21.69 + 1.86; 22.87 + 5.61, 12.99 +2.33; 15.23+3.31 and 4.97+2.73, respectively, P＜0.05).Conclusion These data suggest that the erythrocyte membrane protein composition matched with globin in patients with β-thalassemia of the racial Li minority are different from the normal control. These factors increase rigidity but decrease deformability of the β-thalassemic red cell membrane, which may lead to hemolytic anemia.

Objective To observe the value of myocardial performance index(MPI)for evaluating fetal left ventricular(LV)function in pregnant women with obstetric antiphospholipid syndrome(OAPS).Methods Totally of 41 singleton pregnancy women with OAPS(criteria-OAPS[C-OAPS]group,n=16;non-criteria OAPS[NC-OAPS]group,n=25)and 60 healthy singleton pregnancy women(control group)were prospectively enrolled.Mitral flow E velocities/A velocities,isovolumic relaxation time(IRT),isovolumic contraction time(ICT),ejection time(ET)and MPI of fetal LV were compared among 3 groups.Receiver operating characteristic(ROC)curve was drawn to evaluate the efficacy of MPI for predicting adverse pregnancy outcomes of pregnant woman.Results Significant differences of mitral flow E velocities/A velocities,IRT,ICT,ET and MPI of fetal LV were found among 3 groups(all P＜0.05).Results of pairwise comparison showed that among C-OAPS group,NC-OAPS group and control group,IRT and MPI of LV decreased,whereas E/A and ET of LV increased in order(all P＜0.05).ICT in C-OAPS group was higher than that in control group(P＜0.05).The sensitivity,specificity and area under the curve of MPI for predicting adverse pregnancy outcomes of pregnant woman with OAPS was 90.00％,64.45％and 0.798,respectively.Conclusion MPI could be used to evaluate fetal LV function in pregnant women with OAPS,also being helpful for predicting adverse pregnancy outcomes.

Objective:To investigate the epidemiological characteristics of human respiratory syncytial virus (HRSV) in patients with Severe Acute Respiratory Infection (SARI) in Tianjin from 2015 to 2020.Methods:The study data were obtained from the Third Center Hospital of Tianjin, a designated sentinel hospital, from 2015 to 2020, with 1 597 SARI patients enrolled in this study. The clinical specimens of the research participants were subjected to respiratory multi-pathogen testing. HRSV-positive specimens were subtyped to analyze the differences in HRSV detection rates among cases of different age groups and periods and their mixed infection situations.Results:A total of 1 597 nasopharyngeal swabs were collected, with an HRSV detection rate of 4.20%. Among 67 HRSV-positive specimens, there were 19 pure HRSV-A nucleic acid-positive specimens, 19 pure HRSV-B nucleic acid-positive specimens and 29 mixed HRSV-A and HRSV-B nucleic acid-positive specimens. The difference in HRSV detection rate among different age groups was statistically significant ( P<0.05), and the HRSV detection rate in children under five years old was higher than that in other age groups. From 2016 to 2020, the detection rate of HRSV showed an increasing trend year by year. The HRSV detection rate of SARI cases was highest in the winter season, at 7.15%. There were 10 (14.93%) mixed positive cases for HRSV and other viruses, of which four were mixed positive for HRSV and influenza A. Conclusion:The incidence of HRSV in Tianjin exhibits an increasing trend from 2016 to 2020, peaking during the winter season, with children under five years old constituting a high-risk demographic for HRSV infection.

Objective To observe the value of right ventricle modified myocardial performance index(RV-Mod-MPI)for evaluating maternal obstetric antiphospholipid syndrome(OAPS)involving fetal right ventricular function.Methods Forty-five pregnant women with maternal OAPS(OAPS group)and 60 healthy pregnant women(control group)were prospectively enrolled.Fetal RV-Mod-MPI was obtained with tricuspid and pulmonary valve flow images by applying pulsed wave Doppler(PW).Late pregnancy conditions and data of newborns after delivery were recorded.The indexes were compared between groups.Receiver operating characteristic curve was drawn,and the area under the curve(AUC)was used to assess the efficacy of fetal RV-Mod-MPI for predicting adverse pregnancy outcomes in OAPS group.Results Compared with those in control group,OAPS group had higher fetal RV-Mod-MPI values,lower newborn birth weight and lower Apgar score at 1 min after birth,as well as higher probability of adverse pregnancy outcomes(all P＜0.05).The AUC of fetal RV-Mod-MPI for predicting adverse pregnancy outcome in OAPS group was 0.726.Conclusion RV-Mod-MPI could be used to evaluate maternal OAPS involving fetal right ventricular function and predict adverse pregnancy outcomes.

Objective To evaluate the clinical efficacy of different combinations with "Shugan Jianpi" acupuncture and Yintang acupoint magnetic stimulation in the treatment of depression with liver depression and spleen deficiency type.Methods 160 patients with depression treated in hospital from December 2013 to June 2017 were divided into 4 groups according to the random number table,with 40 cases in each group.Group A received basic drug therapy," Shugan Jianpi" acupuncture combined with Yintang acupoint magnetic stimulation,group B received basic drug therapy combined with Yintang acupoint magnetic stimulation,group C received basic drug therapy combined with " Shugan Jianpi" acupuncture treatment,group D was treated with basic medicine only for 4 weeks.Hamilton Depression Scale (HAMD) was used to assess the short-term and long-term efficacy for 4 groups before treatment,after 2 weeks of treatment,after 4 weeks and 2 months after treatment and the safety of these 4 types of therapy was evaluated with the side effects scale (TESS).2 months after the treatment,the quality of life universal scale (SF-36) was evaluated for patients in 4 groups.Results After 2 weeks,4 weeks and 2 months of treatment,HAMD scores in the 4 groups were significantly lower than those before treatment (P＜0.05).After 2 weeks of treatment,HAMD score of A group was (15.28±3.45),and HAMD score of B,C,D group were ((18.30±3.57),(22.50±3.71),(27.30±4.82)) respectively.HAMD score of A group was significantly lower than those of B,C,D group (P＜0.05).After 4 weeks of treatment,HAMD scores in A,B group were significantly lower than those in C,D group (P ＜0.05).After 2 months of treatment,HAMD scores in all the 4 groups were further declined compared with those after 4 weeks of treatment (P＜ 0.05),however,there was no significant difference between the four groups (P＞0.05).The scores of each dimension of SF-36 in group A were significantly higher than those of group B,C and D (P＜0.05),and which in group B and C were significantly higher than those in D group after 2 months of treatment.(P＜0.05).There was no statistical difference among the 4 groups in TESS scores (P ＞0.05).Conclusion The results suggest that there is a synergistic effect in combination of the " ShuganJianpi" acupuncture combined with Yintang acupoint magnetic stimulation in the treatment of depression of liver qi stagnation and spleen deficiency type,and it can effectively reduce the degree and improve their quality of life in patients with depression.

Objective:To analysis effectiveness of the "14 plus 7 day quarantine" and "nucleic acid plus total antibody testing" strategy (combined screening strategy) for screenin the imported patients with COVID-19 in Xiamen.Methods:The study populations were overseas travelers arriving in Xiamen from March 17 to December 31, 2020, and overseas travelers who had quarantine outside Xiamen for less than 21 days from July 18 to December 31, 2020. Data were collected and analyzed on the timing of detection, pathways, and test results of the imported patients with COVID-19 after implementing combined screening strategy.Results:A total of 304 imported patients with COVID-19 were found from 174 628 overseas travelers and 943 overseas travelers from other cities. A total of 163 cases (53.6%) were diagnosed by multitime, multisite intensive nucleic acid testing after positive finding in total antibody testing. Among them, 27 (8.9%) were first positive for nucleic acid in 14 plus 7 day quarantine and 136 were first positive for nucleic acid in 14-day quarantine. Only 8 of these individuals were tested positive for nucleic acid after positive total antibody testing. The other 128 individuals were tested positive for nucleic acid after being negative for average 2.3 times (maximum of 6 times). Aditional 155 cases might be detected by using the combined "14 plus 7 day quarantine" and " nucleic acid plus total antibody testing" strategy compared with "14-day quarantine and nucleic acid testing" strategy, accounting for 51.0% of the total inbound infections. So the combined screening strategy doubled the detection rate for imported patients with COVID-19. No second-generation case caused by overseas travelers had been reported in Xiamen as of February 26, 2021.Conclusions:Xiamen's combined screening strategy can effectively screen the imported patients with COVID-19 who were first positive for nucleic acid after 14 day quarantine. Compared with "14 day quarantine and nucleic acid testing", the combined screening strategy improved detection rate and further reduced the risk of the secondary transmission caused by the imported patients with COVID-19.
