Background As assessment of the peripapillary retinal nerve fiber layer (RNFL) has been an important approach for detecting structural damage in patients with glaucoma and myopia is a vital risk factor of primary open glaucoma,it is urgent to establish the correlation between RNFL thickness and myopia,not only for understanding the characteristics of RNFL with the change of the degree of myopia,but also for identifying those myopic patients with the early stage of glaucoma.Objective This study was to assess the influence of myopia for the thickness of RNFL measured by 3D optical coherence tomography (3D-OCT).Methods Two hundred and fifty-eight eyes of 258 myopic subjects from General Hospital of Ningxia Medical University were recruited.The myopic eyes were divided into low myopia group (42 eyes,-0.5 D ≤ SE ≤-3.0 D),middle myopia group (120 eyes,-3.0 D＜SE≤-6.0 D),high myopia group (58 eyes,-6.0 D＜SE≤-8.0 D) and extreme high myopia group (38 eyes,SE ＞-8.0 D).The peripapillary RNFL thickness profile including temporal,superior,nasal and inferior quadrants and each of the 12 clocks was measured by 3D-OCT.The measured values were compared among different degrees of myopia,and the correlations between spherical equivalent (SE) and axial length with RNFL thickness were analyzed using linear regression equation.Results The RNFL thickness was gradually declined with the increase of SE and elongation of axis,showing significant differences among the 4 groups in the superior,nasal and inferior quadrants and mean RNFL thickness (F=10.48,15.60,3.31,8.98,all at P＜0.05),but temporal RNFL thickness was increased with the SE rise,with markedly difference among the 4 groups (F =2.92,P =0.03) ; and RNFL thicknesses in the superior,nasal,inferior quadrants and mean RNFL thickness were evidently declined in the high and extreme high myopia group in comparison with low myopia group (all at P＜0.05).The overall RNFL parameters at 1:00,2:00,3:00,4:00,5:00,6:00,8:00,12:00 o'clock sectors were thinning as the increase of SE (all at P＜0.05) and unchanged at the 7:00,9:00,10:00,11:00 sectors in different SE groups (all at P＞ 0.05).Negative correlations were found between axial length or SE with the RNFL thicknesses at superior,nasal and inferior quadrants,average thickness as well as 1:00,2:00,3:00,4:00,5:00,6:00,11:00,12:00 o 'clock,and positive correlation was seen between the axial length or SE with the RNFL thicknesses at temporal quadrant.Conclusions The thickness of RNFL varys with the different degree of myopia and axial length.

Objective:To explore the expression level of IL-17,IL-23 in patients with allergic rhinitis (AR) and their clinical significance.Methods:A total of 25 patients with AR were treated as observe group , and 23 healthy volunteers were chosen as the control group.The levels of serum IL-17,IL-23 and specific-IgE ( s-IgE) were compared between the two groups.The relationships among serum IL-17,IL-23 and sIgE in patients with AR were discussed.Results:The levels of IL-17,IL-23 and sIgE in observe group were significantly higher than in control group.There was a positive linear correlation between the IL-17 and IL-23/the IL-23 and sIgE/the sIgE and IL-17 in observe group.Conclusion: The IL-17 , IL-23 might be the two important cytokine in the occurrence and development process of allergic rhinitis.The IL-17,IL-23 might be related to the formation of sIgE.

This paper was aimed to study the effectiveness and safety of TanshinoneⅡA Sulfonate Sodium Injection in the treatment of unstable angina pectoris (UAP). Keywords such as coronary atherosclerotic heart disease, coronary heart disease, unstable angina, chest impediment, cardialgia, TanshinoneⅡA Sulfonate Sodium Injection, tanshinone injection, tanshinoneⅡA sulfonate, unstable, angina, randomized controlled trial (RCT), and clinical trials were searched in CNKI, VIP, Wanfang and Pubmed from the construction of database until October 31st, 2014. The inclusion criteria were RCT with clinical data integrity, similar literature research methods, and good balance between groups. The Jadad score method was used to carry out quality assessment. Meta-analysis was conducted by RevMan5.2 software. Count data was processed by odds ratio (OR). Measurement data was processed with the weighted mean differences (WMD). The 95% confidence interval (CI) was also calculated. The heterogeneity test result of included literatures was P > 0.05. The fixed effects model was used in the meta-analysis. On the other hand, random effect model was used. For the analysis results of more than 10 papers, the funnel plot was used in the analysis of publication bias. The results showed that a total of 34 studies were included. The results of meta-analysis suggested that the total efficiency of conventional treatment plus TanshinoneⅡA Sulfonate Sodium Injection for UAP was [OR = 3.83, 95%CI (3.11, 4.71),P < 0.000 01]. The electrocardiogram improvement rate was [OR = 3.34, 95%CI (2.61,4.28),P < 0.000 01]; plasma viscosity improvement was [WMD = -0.20, 95%CI (-0.38, -0.03),P = 0.03]; high shear viscosity of whole blood improvement was [WMD = -0.67, 95%CI (-0.85, -0.50),P < 0.000 01]; C-reactive protein improvement was [WMD = -2.66, 95%CI (-3.31, -2.00),P < 0.000 01]. It was concluded that the conventional treatment plus TanshinoneⅡA Sulfonate Sodium Injection for UAP had certain clinical effect with no obvious adverse reaction. However, due to the poor quality of the existing research literatures, the results should be further verified by large amount of high quality RCTs.

OBJECTIVE: To study the methods and efficacy of comprehensive treatment on retractory chronic rhinosinusitis(CRS). METHOD: Thirty-two cases of patients with refractory rhinosinusitis took part in individualized comprehensive treatment program, that is, a healthy diet and moderate exercise, psychological counseling, and reasonable operation and gauze changing, and rational use of drug therapy. RESULT: All patients were followed up for 6 months or more, 26 cases (81.3%) were completely controlled of the disease, 6 cases (18.7%) were partially controlled; the total effective rate was 100%. CONCLUSION In the current situation that CRS etiology and pathogenesis studies have not yet made a breakthrough, and we have not developed a new and effective drug, comprehensive treatment focusing on internal and external factors of refractory rhinosinusitis at the same time, that is, to take a rational healthy diet, moderate exercise, psychological counseling, and reasonable operation and gauze changing, and rational use of drug therapy ect. can obtain better effect.

BACKGROUND: Obtaining synovial fluid for diagnostic test of periprosthetic joint infection is invasive and painful to patients. Platelet count is a regular blood test which has been used as a possible predictor of several infectious diseases. Presumably, it could be one of the indicators of periprosthetic joint infection. OBJECTIVE: To identify the accuracies of platelet combined with white blood cell, erythrocyte sedimentation rate or C-reactive protein in the diagnosis of periprosthetic joint infection. METHODS: Patients undergoing revision arthroplasty from March 2013 to December 2018 in the First Affiliated Hospital of Guangzhou University of Chinese Medicine were retrospectively enrolled. A diagnosis of periprosthetic joint infection was confirmed in 77 patients according to the criterions from the Musculoskeletal Infection Society; the remaining 137 patients were confirmed as aseptic cases. White blood cell, erythrocyte sedimentation rate, or C-reactive protein and platelet count were compared between the two groups. The sensitivity, specificity, positive predictive value, and negative predictive value were calculated. RESULTS AND CONCLUSION: The platelet values were significantly increased in periprosthetic joint infection cases. Sensitivity and specificity of the platelet for periprosthetic joint infection were 64.94％ and 86.13％, respectively. Platelet demonstrated a higher accuracy when compared to erythrocyte sedimentation rate and C-reactive protein. In such cases, the platelet shows a certain reference value in confirming the diagnosis of periprosthetic joint infection. Platelet was enough used as adjunct diagnostic tool in patients suspected with periprosthetic joint infection.

Objective By analyzing the epidemic characteristics and related indicators of SARS (2003) and COVID-19(2020), to explore the reasons for the similarities and differences of the two epidemics, so as to provide reference for epidemic prevention and control. Methods The general situation, clinical classification, activity history, contact history, family members’ contact and incidence of the two infectious diseases in Guangzhou were collected and used to analyze the time characteristics, occupational characteristics, age characteristics and other key indicators of the two diseases, including the number of cases, composition ratio (%), mean, median, crude mortality, etc. Results A total of 1 072 cases of SARS (2003) were included in the study. 353 of which were severe cases with the incidence of 30.13%. 43 cases of death were reported with a mortality rate of 4.01%. The average age was 46 years old, and 26.31% of the cases were medical staff. The interval time between first report to continuous zero reports was 129 days. As to COVID-19 (2020), a total of 346 cases were included. 58 of which were severe cases with the incidence of 16.67%. One case of death was reported with a mortality rate of 0.29%. The average age was 38 years old, and no hospital infection among medical staff was reported. The interval time between first report to continuous zero reports was 35 days. Conclusions The prevention and control strategies for COVID-19 (2010) are more effective compared to that of SARS (2003), and the emergency response procedures are worth to be evaluated and summarized.

Objective To explore the perinatal risk factors of early onset thrombocytopenia (EOT) in full-term small for gestational age infants. Methods A 1:1 or 1:2 matched case control study was carried out. A total of 93 full-term small for gestational age infants with EOT were selected from April 2008 to July 2014 as the case group, and the non EOT full-term small for gestational age infants with the birth weight difference <250 g and the gestational age difference <3 days were selected as the control group. The clinical data during perinatal period and laboratory examination results after admission were collected retrospectively. And the differences between the two groups were compared. Results The incidence of intrauterine distress (41.9％ vs. 25.8％, χ2=7.35, P=0.007), amniotic fluid contamination (39.8％ vs. 27％, χ2=4.66, P=0.031), and early-onset sepsis (39.8％ vs. 27％, χ2=4.66, P=0.031) were significantly higher in the case group than those in the control group. Conditional logistics regression analysis showed that intrauterine distress (β=0.60, OR=1.82, 95％CI=1.04～3.17, P=0.035) and early-onset sepsis (β=1.69, OR=5.44, 95％CI=1.11～26.76, P=0.037) were related to EOT. Conclusions Intrauterine distress and early-onset sepsis are risk factors for the onset of EOT in full-term small for gestational age infants.
