Background Abnormality of intraocular pressure (IOP) leads to ocular shape change and functional damage.Previous study on the influence factors of IOP mostly focus on eye tissue,but the research of systemic affecting factor is lack.Objective This study was to survey the distribution of IOP and its association with the systemic factors in Chinese population.Methods A cross-section study was designed in this study.The subjects were enrolled from the government employees physical check-up cohort in Guangzhou.IOP was measured using non-contact tonometry.The height,weight and blood pressure were measured based on a presupposed standard protocol.Fundus and slit lamp examinations were performed by trained ophthalmologists.Frequency-doubled perimetry was carried out in the subjects with the suspicious optical disc abnormality,and abnormal perimetry result and operated eye were rejected in the survey.The operative history was learned by questionnaire.Stata 11.0 was used for the data analysis.Results Total 7763 subjects finished all the examination,including 4213 male and 3550 female.Four hundred and fifteen subjects were excluded due to previous intraocular surgery and glaucoma,and the clinical data of the right eyes of 7348 subjects who were eligible for the protocol were brought into statistical analysis.The mean IOP was (15.6±2.8) mmHg in the subjects,and that in the male and female subjects was (15.6±2.8) mmHg and (15.7±2.8) mmHg,respectively,showing a statistically significant difference (t =2.415,P =0.016).A good consistence was found in the IOP between the right eyes and the left eyes (r=0.830,P＜0.001).The IOP value in the subjects presented with a near normal distribution.IOP value was gradually decreased with the increase of age.Multivariate regression suggested a negative correlation between IOP and age or gender (P＜0.001) as well as a positive correlation between IOP and body weight index (BMI),systolic blood pressure or diastolic blood pressure (P ＜0.001).Conclusions Similar to other studies in East Asia population,IOP is associated with age,gender,BMI,systolic and diastolic blood pressure in this survey.

Objective To investigate the clinical effect and quality of life of clopidogrel combined with atorvastatin in the treatment of cerebral infrction.Methods 74 patients with cerebral infarction were randomly divided into study group and control group, 37 cases in each group.The control group applied the traditional treatment methods, and the study group were treated with drug combination therapy ( clopidogrel +fluvastatin) on the basis of the control group.After 1 course (6 months), the scores of neurological function and activity, clinical efficacy and quality of life of the two groups were observed and compared.Results National Institutes of Health Stroke Scale ( NIHSS) and Fugl-Meyer were significantly improved in the two groups at discharge (P<0.05), but the improvement degree of the study group was significantly better than the control group (P<0.05).In the control group, 7 cases were ineffective, the effective rate was 81.1%, while the study group was 3 cases, the effective rate was 91.9%, with statistically significant differences(P<0.05), The study group were significantly better than the control group (P<0.05) in the physiological, environmental, health status and quality of life, but the difference was not statistically significant in the psychological and social dimensions.Conclusion Clopidogrel combined with fluvastatin in treating cerebral infarction could significantly improve the treatment efficiency, effectively control blood lipid levels of patients, and improve nerve function and activity ability of patients, and ultimately improve the quality of life of patients.

Objective To explore the TCM syndrome characteristics of cardiac syndrome X(CSX).Methods The signs and symptoms of 51 patients with CSX were analyzed according to the diagnosis of TCM syndromes to summarize their syndrome character- istics.Results of the 51 CSX cases,the following signs and symptoms took dominance:chest pain,fullness in chest,epigastric and abdominal distention,emotional distress,dark purple tongue with petechia,greasy coating,string-taut pulse.The syndromes were mainly of Biao-Superficial excess,including qi stagnation,phlegm retention and blood stasis,occupying 66. 7%,accompanied with Benroot deficiency,including qi deficiency,yin deficiency,qi and yin both deficiency,occupying 33.3%.Conclusion Qi stagnation, phlegm retention and blood stasis are the primary syndromes of CSX.

OBJECTIVE: To explore the relation between the behavior psychology analysis of partial mechanical injuries and the nature of death in high-falling cases, and provide reference, for such cases. METHODS: Of 311 death victims of high-falling injuries collected from 2008 to 2013, 205 cases were associated with partial mechanical injuries. The characteristics of injury formation, preliminary crime scene traces, fatal injury of high-falling, and text messages were all retrospectively analyzed. RESULTS: According to the investigation of preliminary crime scene traces, fatal injury of high-falling and text message, there were 86 suicide, 24 accident and 95 uncertainty in the 205 cases. According to the behavior psychology analysis of partial mechanical injuries, there were 80 suicide, 11 accident, and 4 homicide in the 95 uncertainty cases. CONCLUSION The partial mechanical injuries uncertainly caused by high-falling correlate with the manner of high-falling death. According to the behavior psychology analysis of the partial mechanical injuries in high-falling death cases, the presumption of high-falling death is usually accurate

Objective:To investigate the effects of establishment of a trauma center on the therapeutic efficacy for patients with severe multiple injuries.Methods:A retrospective study was conducted in the patients who had been treated at The Second Affiliated Hospital, University of South China for severe multiple injuries from October 2015 to September 2019. They were assigned into 2 groups. The study group included 102 patients who had been treated after establishment of our trauma center (from October 2017 to September 2019) while the control group 126 patients who had been treated before establishment of our trauma center (from October 2015 to September 2017). The 2 groups were compared in terms of time for emergency treatment (from admission to emergency surgery or ICU), ICU stay, hospital stay, total medical costs and mortality.Results:There was a significant difference between the 2 groups in time for emergency treatment [51 (47, 57) min for the study group versus 97 (87, 107) min for the control group] ( P<0.05). There were no significant differences between the 2 groups in ICU stay [4 (1.8, 9.3) d versus 4 (2.0, 10.0) d], hospital stay [25.5 (15.8, 39.0) d versus 21.5 (12.8, 41.5) d], or total medical costs [￥41,259.0 yuan (￥26,950 yuan, ￥81,599 yuan)] ( P>0.05). There was a significant difference between the 2 groups in mortality [12.7% (13/102) for the study group versus 24.6% (31/126) for the control group] ( P<0.05). Conclusion:Establishment of a trauma center can effectively shorten time for emergency treatment, improve treatment efficacy and reduce mortality for patients with severe multiple injuries.
