Objective To study the effects of enhanced external counterpulsation (EECP) on the diastolic heart failure in hypertensive patients.Methods 104 hypertensive patients with diastolic heart failure were randomly divided into treatment group and control group,52 patients were given 36 hours of treatment EECP.After 6 months,Doppler ultrasound recordings were obtained from all patients to determine the left ventrlcular diastolic function.Resuits Left ventricular diastolic function index and the left ventrich mass weight index (LVMI) wero impmved after treatment in both groups(P＜0.01),and EECP treated group was better than control group(P＜0.05).Conduslon For hypertensive patients with diastolic heart failure,EECP could not only improve heart diastolic function,but also reverse reconstruction of the left ventricuhr.

Objective To investigate the relationship between resting heart rate(RHR) and prognosis of acute coronary syndromes without ST-segment elevation.Methods 167 patients of ACS without ST-segment elevation admitted to hospitals consecutively from Oct. 2001 to Oct. 2004 were divided into five groups according to the levels of RHR[RHR 1 group:RHR

Objective To summarize the clinical characteristic and therapeutic efficacy of lacunar infarction after craniocerebral trauma.Methods 37 cases of children with lacunar infarction after craniocerebral trauma from December 2000 to December 2004 were retrospectively analyzed.Results All of the 37 sufferers received the expectant treatment in hospital.Among the 37 cases,30(81.1%) were well-healed and 7(18.9%) were light maimed when leaving hospital.The clinical symptom of the 29 sufferers completely faded and 7 patients who were light maimed recoverd during the follow-up visit for 6 to 12 months.Conclusions Lacunar infarction after craniocerebral trauma is the syndrome of the damage of the nervous system.Its' major manifestation is the disorder of half body movement.Children with light craniocerebral trauma get this kind of disesase easily.CT scanning and regular re-X can predominantly raise the of the final diagnosis.Most of the sufferers can receive good long-term therapeutic efficacy.

Objective To explore the effects of hyperbaric oxygen (HBO) treatment on expression of extra-cellular signal regulated kinase 1/2 (ERK 1/2) and neurological function in acute traumatic brain injury (TBI) rats so as to offer trial support for clinical application of HBO in TBI.Methods Twenty-four adult Sprague-Dawley rats were randomly divided into sham-operation group,TBI group and HBO treatment group,with eight rats per group.The sham-operation group was free from TBI but skull was opened only but the TBI group was subjected to TBI according to Alice method.TheHBO treatment group was treated with HBO for 10 days ( one time per day) after TBI operation.On day 14,NSS rating was performed in all rats.Then,the rats were sacrificed and cortex of which was obtained to measure the expression of ERK1/2 by using reverse transcription-polymerase chain reaction (RT-PCR).The localization of the expression of ERK was detected by immunohistochemical staining and the changes in ERK protein was analyzed by optical density.Results The NSS score in the HBO group was significantly decreased at day 14 after HBO treatment ( P ＜ 0.01 ) and the expression of ERK1/2 in HBO group was also significantly decreased (P ＜ 0.05 ) in comparison with the TBI group.Conclusions HBO treatment can significantly decrease NSS score and expression of ERK1/2 in acute TBI rats,indicating that HBO may improve neurological function through down-regulating expression of ERK1/2.

Objective To study the effects of hyperbaric oxygen on the diastolic heart failure in hypertensive patients. Methods 60 hypertensive patients with diastolic heart failure were randomly divided into treatment group and control group. Conventional therapies were given to patients of both groups. In addition, hyperbaric oxygen therapy was applied to those of treatment group. After 3 months, Doppler ultrasound recordings were obtained from all patients to determine the left ventricular diastolic function. Results The indexes of left ventricular diastolic function were im-proved after treatment in both groups(P < 0.01) ,and treatment group was better than control group(P < 0. 05). Conclusion For hypertensive patients with diastolic heart failure, hyperbaric oxygen can improve heart diastolic function.

Objective To study hyperbaric oxygen on left ventricular ejection fraction preserved by the influence of left ventricular remodeling in patients with heart failure. Methods A total of 110 patients with heart failure and normal ejection fraction were randomly allocated into the control group (n=55) and the HBO group (n=55). The control group were given the routine therapy, the HBO group were treated with hyperbaric oxygen on the basis of conventional drug. The application of color doppler ultrasound before and after treatment for 3 months left ventricular structure indicators. Results Left ventricular structure indicators were significantly decreased (LVDd、IVSD、LVPWD、LVMI)(P<0.01). Compared with the control group the difference was statistically significant (P<0.05). Follow-up of 3 months, The treatment group composite cardiovascular events was fewer than the control group and had significant difference (P<0.05). Conclusion Hyperbaric oxygen therapy can significantly improve left ventricular ejection fraction preserved by heart failure of left ventricular diastolic and systolic function and reverse left ventricular remodeling,And can reduce the happening of cardiovascular events.

Objective:To systematically evaluate the effect of repeated low-level red light (RLRL) therapy on controlling the progression of myopia in children.Methods:Medline, Embase, Cochrane Library, Web of Science, ClinicalTrial.gov and the CNKI, VIP, Wanfang database, and Chinese Clinical Trial Registry (www.chictr.org.cn) were searched from their establishment to September 2022 to obtain the randomized controlled trial (RCT) about RLRL controlling myopia progression in children.Grey literature was also searched.Inclusion and exclusion criteria were developed according to the PICOS principle.Two researchers screened the literature independently, extracted data, and assessed the risk of bias in the included studies using the Cochrane collaboration tool for assessing risk of bias.The data were imported into RevMan 5.4 software for meta-analysis.Mean and standard deviation of data were used to obtain mean differences and 95% confidence intervals of included studies.Changes in spherical equivalent (SE) and axial length (AL) were compared between before and after the intervention in RLRL and single-vision spectacle (experimental group) and single-vision spectacle (control group). The GRADE system was used to grade the quality of evidence for the outcome indicators.Results:A total of 157 studies were obtained.After the screening, 7 RCT studies including 1 038 study subjects met the inclusion criteria.Meta-analysis results showed that retarded SE progression was retarded and AL elongation was reduced significantly after different follow-up durations (1, 3, 6, 12 and 24 months) in experimental group compared with control group.As the follow-up duration extended from 1 month to 24 months, the retard of SE progression increased from 0.14 to 0.93 D, and the reduction of AL increased from 0.07 to 0.48 mm.Both 635 and 650 nm red light significantly retarded SE progression and reduced AL elongation.The two outcome indicators, SE change and AL change were moderate-strength evidence by GRADE.Conclusions:The current moderate-strength evidence shows that RLRL can better retard myopia progression in children than single-vision spectacle glasses.

Objective: To investigate the current situation and associated factors of computer vision syndrome (CVS) among college freshmen in Tianjin during the COVID-19 epidemic, and to provide a reference for visual comfort of college students. Methods: A total of 868 college freshmen from one university in Tianjin were administered with CVS qualitative analysis questionnaire, eye health status questionnaire and eye health examination during Oct to Dec 2021. Chi square test and multivariate Logistic regression were used for data analysis. Results: The detection rate of CVS among the included students was 68.5% ( n =595) and was higher in females (72.2%) than in males (61.7%). The CVS detection rate in girls, students without myopia, >30 min sleep onset, >1 h mobile phone usage, and ≤8 h sleep duration (72.2%, 70.4%, 81.1%, 72.7%, 71.2%) were significantly higher than boys, students with low grade myopia, sleep onset required ≤30 min, use mobile phone for ≤1 h, and sleep duration >8 h(61.7%, 63.3 %, 67.4%, 65.9%, 61.1%) ( χ 2=10.08, 3.94, 5.89, 4.40, 7.94, P ＜0.05). Differences in CVS detection rates varied significantly by daily electronic device usage and academic stress students ( χ 2=22.03, 21.24, P ＜0.05). Multivariate Logistic regression analysis showed that daily use of electronic devices 4-6, 7-9, ≥10 h, sleep onset required >30 min, moderate to higher academic pressure were positively associated with CVS ( OR=1.95, 2.94, 2.30, 2.39, 3.51, 4.41, P ＜0.05), boys, low grade myopia, night sleep time >8 h were negatively associated with CVS ( OR=0.65, 0.70, 0.65, P ＜0.05). Conclusion The detection rate of CVS among freshmen in a university in Tianjing is high. Attention should be paid to the CVS situation of students with e learning, and general public should also be educated to reduce the time of unnecessary electronic product use and ensure night sleep to reduce the prevalence of CVS.

Objective:To investigate the prevalence and risk factors of tessellation fundus (TF) among Tianjin Medical University students with different refractive statuses.Methods:A cross-sectional study. From September to December 2019, 346 students from Tianjin Medical University were randomly selected and underwent slit-lamp examination, non-cycloplegic auto-refraction, subjective refraction, best-corrected visual acuity, ocular biometric measurement, and non-dilation fundus photography. The differences in the prevalence of TF in basic characteristics and ocular biometric parameters were compared. Based on the equivalent spherical (SE), refractive status was divided into the non-myopia group (SE>-0.50 D) and the myopia group (SE≤-0.50 D). The myopia group was further divided into mild myopia group (-3.00 D26 mm group. The logistic regression was used to analyze the risk factors affecting TF. Trend tests were performed for each risk factor and TF.Results:Of the 346 subjects, 324 (93.6%, 324/346) were myopia, of whom 73 (21.1%, 73/346), 167 (48.3%, 167/346), and 84 (24.3%, 84/346) were mild myopia, moderate myopia, and high myopia, respectively; 22 (6.4%, 22/346) were non-myopia. There were 294 (85.0%, 294/346) students with TF in the macula, including 9 (40.91%, 9/22), 58 (79.45%, 58/73), 145 (86.83%, 145/167), and 82 (97.62%, 82/84) in non-myopia, low myopia, moderate myopia, and high myopia group, respectively; 52 (15.0%, 52/346) students were without TF in the macula. There were statistically significant gender differences ( χ2=4.47), SE ( t=6.29), AL ( t=-8.29), anterior chamber depth ( Z=-2.62), lens thickness ( Z=-2.23), and average corneal radius ( Z=-3.58) between students with and without TF in the macula ( P<0.05). Spherical equivalent and axial length were independent risk factors for TF and its severity ( P≤0.001). With an increasing degree of myopia, and increasing axial length, the risk of TF increased ( P for trend<0.001). Conclusions:The prevalence of TF is 85.0% among Tianjin Medical University students. TF is detected in the fundus of no myopia, mild myopia, moderate myopia and high myopia. The degree of myopia is higher, the AL is longer, the possibility of TF is higher.
