ABSTRACT

BACKGROUND:Some studies have shown that the hounsfield units(HU)value based on lumbar CT can be used to screen osteoporosis.At present,the number of patients with pulmonary infection has increased;the number of patients with pulmonary infection and type 2 diabetes is also increasing,which increases the utilization rate of chest CT. OBJECTIVE:To investigate the role of lumbar 1 vertebral body HU value based on chest CT in the screening of type 2 diabetes mellitus osteoporosis. METHODS:The clinical data of 244 patients with type 2 diabetes mellitus treated in the First Affiliated Hospital of Chengdu Medical College from June 2020 to June 2022 were analyzed retrospectively.The bone mineral density was obtained by dual-energy X-ray absorptiometry.According to WHO's diagnostic criteria for osteoporosis,the subjects were divided into the non-osteoporosis group(n=120)and the osteoporosis group(n=124).The general condition,T value and HU value of lumbar 1 vertebra in chest CT were compared,and the relationship between the HU value and T value of each position was analyzed and the accuracy of type 2 diabetes mellitus osteoporosis was evaluated. RESULTS AND CONCLUSION:(1)There was no significant difference in sex,age,body mass index,glycosylated hemoglobin,mean blood glucose,calcium(Ca),phosphorus(P),time of type 2 diabetes mellitus,history of hypertension and history of hyperlipidemia between the two groups(P>0.05).(2)The HU value was positively correlated with the lowest T value of the hip(r=0.619,P<0.01);the HU value was positively correlated with the hip T value(r=0.584,P<0.01),and the HU value was positively correlated with the femoral neck T value(r=0.641,P<0.01).When the HU value was 98,the prediction of type 2 diabetes mellitus osteoporosis had good accuracy,and the sensitivity was 70.8%.(3)It is concluded that the HU value of the lumbar 1 vertebra based on chest CT examination is of good value for osteoporosis screening in patients with type 2 diabetes mellitus,and may be an opportunistic and cost-free supplementary screening method for type 2 diabetes mellitus osteoporosis.

ABSTRACT

BACKGROUND:The development of steroid-induced osteonecrosis of the femoral head is a complex process involving multiple mechanisms.There is still no standard therapeutic drug for early intervention of this disease.Current studies have shown that baicalein has various pharmacological activities such as regulating lipid metabolism,bone metabolism,apoptosis and anti-oxidative stress,which provides an idea for the prevention and treatment of steroid-induced osteonecrosis of the femoral head. OBJECTIVE:To observe the preventive effect of baicalein against steroid-induced osteonecrosis of the femoral head and to investigate its possible mechanism. METHODS:Thirty-six 10-week-old male Sprague-Dawley rats were randomly divided into three groups(n=12 per group):blank control group,model group,and baicalein intervention group.In the model group and baicalein intervention group,intraperitoneal lipopolysaccharide and intramuscular injection of methylprednisolone sodium succinate were performed for modeling,while normal saline was used as a substitute for the modeling drug in the blank control group.Baicalein 300 mg/kg was administered by gavage(once a day for 6 weeks)at the time of initial intramuscular glucocorticoid injection in the baicalein intervention group,and baicalein was replaced by normal saline in the other two groups.The serum level of malondialdehyde in rats was detected at 2 weeks of the experiment.Blood lipid indicators and bone formation metabolic markers were detected at 6 weeks of the experiment,the histomorphometric changes of the femoral head were analyzed by hematoxylin-eosin staining,anti-tartaric acid phosphatase staining and TUNEL staining,and the femoral head was subjected to Micro-CT scanning and three-dimensional reconstruction of the bone in order to analyze the alterations of bone tissue structure and parameters. RESULTS AND CONCLUSION:The serum levels of malondialdehyde,triglyceride,β-collagen type Ⅰ carboxy-terminal peptide were increased and the serum levels of bone specific alkaline phosphatase and pre-collagen type Ⅰ amino-terminal peptide were decreased in the model group compared with the blank control group(P<0.05).The serum level of malondialdehyde decreased in the baicalein intervention group compared with the model group(P<0.05),but there was no significant difference between the baicalein intervention group and blank control group(P>0.05).The serum level of triglyceride was higher in the baicalein intervention group than the blank control group(P<0.05),but had no significant difference between the baicalein intervention group and model group(P>0.05).There were also no significant differences in the levels of bone specific alkaline phosphatase and β-collagen type Ⅰ carboxy-terminal peptide between the baicalein intervention group and the other two groups(P>0.05).The serum level of the baicalein intervention group was lower in the baicalein intervention group than the blank control group(P<0.05)but had no significant difference between the baicalein intervention group and model group(P>0.05).Histomorphological analysis of the femoral head showed that the rate of bone empty lacuna,osteoclast counting and cell apoptosis rate in the femoral head of model group rats were significantly higher than those of the other two groups(P<0.05).There was a significant increase in the number of adipocytes in the bone marrow cavity of the femoral head,bone trabeculae were thinned and sparsely arranged with more disruptions in the continuity.The incidence of osteonecrosis was higher in the model group(75%)than in the baicalein intervention group(25%;bilateral and unilateral exact significance results were both 0.05).There was also an increase in the number of adipocytes in the bone marrow cavity of the femoral head in the baicalein intervention group,and the trabecular changes were roughly similar to those in the model group.Micro-CT results showed that bone volume fraction,trabecular thickness,trabecular number,and bone mineral density decreased and trabecular separation increased in the model group compared with the blank control group(P<0.05).Overall significant bone mass loss was observed in the model group.Bone tissue parameters in the baicalein intervention group were significantly improved than those in the model group,which were reflected in bone volume fraction,trabecular thickness and trabecular separation(P<0.05),and trabecular number and bone mineral density had no significant difference between the baicalein intervention group and blank control group(P>0.05).Although baicalein failed to significantly ameliorate dyslipidemia and promote bone formation in rats with steroid-induced osteonecrosis of the femoral head,it could reduce the incidence of steroid-induced osteonecrosis of the femoral head by reducing oxidative stress damage,decreasing cell apoptosis,inhibiting osteoclasts,suggesting its effectiveness in the early prevention of steroid-induced osteonecrosis of the femoral head.

ABSTRACT

OBJECTIVE@#To explore the clinical outcomes of anteromedial combined with lateral locking plate for complex proximal humeral fractures in the eldery.@*METHODS@#From June 2018 to October 2020, 30 patients who underwent surgical treatment for Neer grade 3 to 4 proximal humeral fractures, including 8 males and 22 females, aged from 51 to 78 years old with an average of (61.5±7.5) years old. Of them, 15 patients had fractures fixed with anteromedial combined with lateral locking plate(ALLP group), whereas 15 received internal fixation with proximal humerus locking plate only(PHLP group). The clinical data, simple shoulder test (SST), humeral head height loss, varus angle and shoulder range of motion were compared between the two groups.@*RESULTS@#All fractures were healed. The follow-up time ranged from 12 to 24 months, with an average of(14.3±2.9) months. The operation time of ALLP group was longer than that of PHLP group (P<0.05). There was no significant difference in intraoperative blood loss between the two groups (P>0.05). There was no significant difference in SST score between the two groups at 1, 3 and 12 months after operation (P>0.05). In terms of radiographic measurement, there was no significant difference in humeral head height loss and varus angle between the two groups at 1 and 3 months after operation (P>0.05). At 12 months after operation, the height loss and varus angle of humeral head in ALLP group were lower than those in PHLP group (P<0.05). In shoulder range of motion, the range of forward elevation in ALLP group was larger than that in PHLP group 1 year after operation(P<0.05). There was no significant difference in external rotation between the two groups.@*CONCLUSION@#Anteromedial combined with lateral locking plate in the treatment of complex proximal humeral fractures in the elderly can increase the stability of the medial column and obtain a good fracture prognosis. But there are also disadvantages such as longer operation time, so it should be individualized according to the fracture type of the patient.

ABSTRACT

The pharmaceutical manufacturing model is gradually changing from intermittent manufacturing to continuous manufacturing and intelligent manufacturing. This paper briefly reviewed the supervision and research progress in continuous pharmaceutical manufacturing in China and abroad and described the definition and advantages of continuous pharmaceutical manufacturing. The continuous manufacturing of traditional Chinese medicine(TCM) at the current stage was summarized in the following three terms: the enhancement of the continuity of intermittent manufacturing operations, the integration of continuous equipment to improve physical continuity between units, and the application of advanced process control strategies to improve process continuity. To achieve continuous manufacturing of TCM, the corresponding key technologies, such as material property characterization, process modeling and simulation, process analysis technology, and system integration, were analyzed from the process and equipment, respectively. It was proposed that the continuous manufacturing equipment system should have the characteristics of high speed, high response, and high reliability, "three high(H~3)" for short. Considering the characteristics and current situation of TCM manufacturing, based on the two dimensions of product quality control and production efficiency, a maturity assessment model for continuous manufacturing of TCM, consisting of operation continuity, equipment continuity, process continuity, and quality control continuity, was proposed to provide references for the application of continuous manufacturing technology for TCM. The implementation of continuous manufacturing or the application of key continuous manufacturing technologies in TCM can help to systematically integrate advanced pharmaceutical technology elements and promote the uniformity of TCM quality and the improvement of production efficiency.

ABSTRACT

OBJECTIVE@#To investigate the clinical efficacy of acrylic cement (PMMA) mixed with calcium sulfate combined with percutaneous kyphoplasty (PKP) in the treatment of osteoporotic fracture (OVCF).@*METHODS@#The clinical data of 191 patients with OVCF treated with PKP from January 2020 to March 2021 were retrospectively analyzed. Among them, 82 patients with 94 vertebral bodies were treated with PMMA mixed with calcium sulfate as the observation group, and 109 patients with 125 vertebral bodies were treated with pure PMMA as the control group. Among the 82 patients in the observation group, there were 16 males and 66 females, with a mean age of (75.35±11.22) years old, including 36 thoracic vertebrae and 58 lumbar vertebrae. In the control group, there were 109 patients, 22 males and 87 females, with an average age of (74.51±9.21) years old, including 63 thoracic vertebrae and 62 lumbar vertebrae. The visual analog scale (VAS) before operation and 1 day, 3 months and 1 year after operation were calculated. The Oswestry disability index (ODI), Cobb's angle, vertebral body height and the probability of postoperative bone cement leakage were used to analyze the efficacy of the two groups.@*RESULTS@#All the patients were followed up for more than one year. Compared with the control group, there was no significant difference in operation time, bleeding volume and bone cement injection volume between the two groups(P>0.05), while the leakage rate of bone cement was significantly lower in the observation group (P<0.05). In addition, there was no significant difference in VAS, ODI, Cobb angle, and vertebral body height between the two groups before operation, and 1 day, 3 months, and 1 year after operation (P>0.05), but each index was improved compared with that before operation (P<0.05).@*CONCLUSION@#PMMA mixed with calcium sulfate has equivalent efficacy in treating OVCF than PMMA alone, but can effectively reduce the probability of cement leakage.

ABSTRACT

Objective: To investigate the clinical efficacy of long-segment pedicle screw reduction and internal fixation combined with kyphoplasty in the treatment of stage Ⅲ reducible Kummell disease. Methods: The clinical data of 32 patients with stage Ⅲ reducible Kummell disease treated at the Department of Orthopedics, Sir Run Run Shaw Hospital, Zhejiang University College of Medicine from January 2012 to March 2017 were analyzed retrospectively.There were 7 males and 25 females,aged (71.8±6.7)years(range:61 to 86 years).The injured segment was T10 in 1 patient,T11 in 8 patients,T12 in 13 patients,L1 in 7 patients,L2 in 2 patients and L3 in 1 patient.Preoperative American spinal injury association(ASIA) classification of patients all showed grade D.Bone mineral density (BMD),spinal X-ray,CT and MRI were examined before operation.All patients were treated with postural reduction, long-segment pedicle screw reduction and internal fixation combined with kyphoplasty.The operation time,intraoperative blood loss,length of stay and postoperative complications were recorded.The visual analogue scale (VAS) and Oswestry dysfunction index (ODI) as well as the BMD of hip were collected before and after operation.The Cobb angle of involved segment kyphosis and the height of anterior edge of diseased vertebrae were measured before operation,3 days and 12 months after operation.CT-related parameters were measured before and 3 days after operation,including sagittal anterior and posterior diameter of spinal canal,cross-sectional anterior and posterior diameter of spinal canal and cross-sectional spinal canal area.Paired sample t test and repeated measures were used to compare the data before and after operation. Results: All patients received the operation successfully.The operation time was (131.3±16.9) minutes (range:95 to 180 minutes),the blood loss was (82.5±27.1) ml (range:50 to 150 ml),and the length of stay was (8.3±2.4) days (range:5 to 14 days).All patients were followed up for more than 12 months.The VAS decreased gradually at 3 days,3 months,6 months and 12 months after operation,and the differences were statistically significant compared with the VAS before surgery (all P<0.01).ODI at 3,6 and 12 months after surgery was significantly improved compared with that before surgery(All P<0.01).The CT-related parameters at 3 days after operation were significantly higher than those before operation (All P<0.05).At 12 months after surgery,the Cobb angle decreased from (35.2±7.6) ° preoperatively to (4.3±1.7) ° (t=22.630,P<0.01),the height of anterior edge of diseased vertebrae increased from (4.3±1.0) mm preoperatively to (16.9±2.5) mm(t=-25.845,P<0.01),the bone mineral density of hip increased from -(2.2±0.6) preoperatively to -(2.8±0.6)(t=-0.040,P<0.01).Up to the last follow-up,2 patients had distal pedicle screw loosening, 1 patient had proximal junctional kyphosis,and there was no new vertebral fracture. Conclusions: Based on postural reduction,long-segment pedicle screw reduction and internal fixation combined with kyphoplasty is a safe and effective treatment method for stage Ⅲ reducible Kummell disease,which can reconstruct the stability of the diseased vertebrae.Postoperative standard anti-osteoporosis treatment is the basis to ensure the efficacy.

ABSTRACT

@#Abstract: Objective This paper aims to explore the effect of live attenuated varicella vaccine on the sensitivity of tuberculin skin test(TST), and to provide reference for tuberculin skin test in the future. Methods TST and emergency varicella vaccine were administered to students in grade one of a high school in Wuxi, Jiangsu province, who had both TB and varicella cases. Independent-samples t test was used to analyze the mean diameter of induration of TST in day 0, day 83 and day 195. The retrospective cohort study was used to analyze the effect of live attenuated varicella vaccine on TST.   Results The mean induration diameter of 45 students who participated in three TST tests on day 0, day 83 and day 195 were analyzed by independent sample t test. On day 0, there was a difference in the mean diameter of TST induration between the unvaccinated and vaccinated groups(1.630±2.837 vs 5.818±4.530) (t=-3.692, P=0.001). On day 83, there was no difference in the mean diameter of TST induration between the two groups(0.001±0.001 vs 0.114±0.533) (t=-1.000, P=0.329). On day 195, there was a difference in the mean diameter of TST induration between the two groups(1.913±3.774 vs 5.023±5.126) (t=-2.309, P=0.026). Moreover, the retrospective cohort study showed that the mean diameter of TST induration changed more significantly after inoculation with varicella vaccine, RR=6.071, 95%CI (1.667-22.116), P<0.05; After inoculation with varicella vaccine, the mean diameter of TST test did not change significantly from day 0 to day 195 with no statistical significance RR=3.474, 95%CI (0.333-36.240), P>0.05. Conclusions Live attenuated varicella vaccine may temporarily affect the sensitivity of tuberculin skin test.

ABSTRACT

Chronic atrophic gastritis (CAG) and gastric intestinal metaplasia (GIM) significantly increase the risk of gastric cancer. Blocking the development of CAG and GIM would help to decrease the incidence of gastric cancer. It was revealed that eradication of Helicobacter pylori could reverse gastric mucosa atrophy. Recent studies reported that GIM could be reversed to a certain extent. Clinical studies demonstrated that Lamb′s tripe extract and vitamin B12 capsule exhibited significant reversal effects on GIM. The present study systemically reviewed the diagnosis and treatment of CAG and clinical application of Lamb′s tripe extract and vitamin B12 capsule, and established the specialist instruction that would guide the reversal treatment of CAG and GIM.

ABSTRACT

Objective To investigate the clinical application value of the levels of heparin-binding protein (HBP) in cerebrospinal fluid (CSF) for intracranial infectious diseases. Methods A case-control study was conducted. 150 patients after craniotomy(73 in the postoperative bacterial intracranial infection group, 77 in the postoperative non-infection group) admitted to the Department of Neurology of the People's Hospital of Liaoning Province from December 2016 to May 2018 were collected. At the same time, 46 patients without operation (14 in the non-bacterial intracranial infection group, 32 patients without intracranial infection were selected as control group whose white blood cell count (WBC) values in CSF were all below 10 × 106/L) in the same period were also collected. According to the diagnostic criteria for severe intracranial infection, the patients with bacterial intracranial infection were divided into 26 cases of mild intracranial infection group and 47 cases of severe intracranial infection group. According to the Glasgow Outcome Scale (GOS) score at the time of discharge, the patients were divided into 30 cases of good prognosis group (GOS score 4-5 points) and 43 cases of poor prognosis group (GOS score 1-3 points). The concentrations of HBP in CSF were tested with latex immunoturbidimetry, and the concentrations of procalcitonin(PCT) in cerebrospinal fluid and serum were tested with electrochemiluminescence, and cerebrospinal fluid routine were tested with instrument method, and the concentrations of total protein(TP) in cerebrospinal fluid were tested with turbidimetry. The differences of the laboratory test indicators in each group were statistically analyzed, and the levels of HBP in CSF of patients with different degrees of intracranial infection and different prognosis were compared. Comparison of two independent samples was performed using the Mann-Whitney U test. Results The HBP levels in cerebrospinal fluid were 187.00 (73.00, 635.00) ng/ml, 10.00 (3.50, 32.00) ng/ml, 1.50 (0, 4.00) ng/ml, 3.00 (1.00, 4.00) ng/ml in post-craniotomy bacterial intracranial infection group, uninfected group after craniotomy, non-bacterial intracranial infection group and control group respectively. The cerebrospinal fluid levels of WBC count were 1280.00 (363.00, 4327.00)×106/L, 63.00 (18.50, 300.00)×106/L, 5.00 (3.00, 14.75)×106/L, 3.00 (2.00, 5.75)×106/L. The absolute value of cerebrospinal fluid neutrophils were 1216.00 (225.50, 3895.50)×106/L, 24.00 (2.00, 209.50)×106/L, 1.00 (1.00, 3.00)×106/L, 1.00 (1.00, 1.00)×106/L. The cerebrospinal fluid levels of PCT were 0.16 (0.10, 0.32) ng/ml, 0.09 (0.07, 0.14) ng/ml, 0.07 (0.06, 0.12) ng/ml, 0.07 (0.06, 0.13) ng/ml. The serum levels of PCT were 0.36 (0.15, 1.09) ng/ml, 0.09 (0.04, 0.16) ng/ml, 0.08 (0.04, 0.13) ng/ml, 0.07 (0.03, 0.11) ng/ml. The levels of HBP, WBC, neutrophils, PCT in CSF and serum PCT in the post-craniotomy bacterial intracranial infection group were significantly higher than those in the uninfected group after craniotomy (Z=-9.246,-6.759,-6.741,-4.477,-6.202, P<0.05), non-bacterial intracranial infection group(Z=-5.840,-5.412,-5.259,-2.923,-5.104,P<0.05) and the control group (Z=-7.905,-7.919,-7.335,-4.397,-5.474, P<0.05). There were significant differences in the levels of HBP, WBC and neutrophils in CSF(Z=-3.763,-3.444,-3.041,P<0.05) and no significant differences in CSF and serum PCT (Z=- 0.869, - 1.850, P>0.05)between the uninfected group after craniotomy and the non-bacterial intracranial infection group. There were significant differences in the levels of HBP, WBC and neutrophils in CSF(Z=-4.496,-6.685,-4.842,P<0.05) and no significant differences in CSF and serum PCT(Z=-0.676,-1.303, P>0.05)between the uninfected group after craniotomy and the control group. There were no significant differences in the levels of HBP, PCT in CSF and serum PCT (Z=-0.861,-0.514,-0.273, P>0.05)and significant differences in the levels of WBC and neutrophils in CSF(Z=-2.756,-3.060, P<0.05) between the non-bacterial intracranial infection group and the control group. The levels of HBP in CSF in the severe intracranial infection group were significantly higher than those in the mild intracranial infection group(Z=-6.267, P<0.05). The levels of HBP in CSF in the poor prognosis group were significantly higher than those in the good prognosis group(Z=-7.064, P<0.05). The area under the ROC curve for the diagnosis of bacterial intracranial infection by HBP, WBC, neutrophils, TP, PCT in CSF and PCT in serum was 0.986, 0.987, 0.945, 0.945, 0.770 and 0.914, respectively. The area under the ROC curve for differential diagnosis of bacterial intracranial infection and non-bacterial intracranial infection was 0.994, 0.958, 0.961, 0.929, 0.747 and 0.936, respectively. Conclusions HBP in CSF is an ideal indicator for the diagnosis of bacterial intracranial infection. It is important to distinguish between bacterial intracranial infection and non-bacterial intracranial infection. The extent of increase is related to the severity of infection and prognosis of the disease.

ABSTRACT

Orchidaceae (Orchidaceae) is the second largest family of angiosperms. It’s the "flagship" group in plant protection. The existence of orchid plant is closely related to mycorrhizal fungi. The relationship between orchids and their symbiotic mycorrhizal fungi is a benefit to the protection and population restoration of orchids. Aims: The research was aimed to study molecular identification about 15 strains of mycorrhizal fungi from 6 plots by rDNA ITS technology in order to understand and utilise the mycorrhizal fungi of Liparis japonica (Miq.) Maxim. Study Design: The mycorrhizal fungi collected from different geographical locations were isolated and purified from the mycorrhizal fungi symbiotic with Liparis japonica in Northeast China, which were identified by rDNA ITS, meanwhile computed evolutionary distance and constructed the phylogenetic tree. Place and Duration of Study: In 2017, the root segments of Liparis japonica were collected separately from Qianshan, Changbaishan, Gaoguan, Guanmenshan, Dongling, Daqinggou. Methodology: Fifteen strains of mycorrhizal fungi collected from six plots were identified by rDNA ITS. Using DNAMAN software to analyse, the pairwise homology was compared by using the optimal global sequencing option. The evolutionary distances of fifteen strains were calculated by MEGA (Molecular Evolutionary Genetics Analysis) software package and their phylogenetic trees were constructed by neighbour-joining method. Results: With primers ITS1 and ITS4, the 15 mycorrhizal fungi strains of rDNA ITS got about 600 bp length. ITS length was about 582-613 bp, in which ITS1 length was about 177-190 bp, and ITS2 length was 246-273 bp. The mycorrhizal fungi strains were highly homology separated from one plot, mostly above 90%. The plots from the south to the north were as follows: Qianshan, Guanmenshan, Gaoguan, Dongling, Changbaishan, Daqinggou in China. Fifteen strains after separated and purified were identified to be the Epulorhiza of Orchid Rhizoctonia blasted with Genbank. The homology of the strains gradually decreased affected by the difference of the north and the south, namely there was an increasing trend of diversity from south to north. Conclusion: The homology of mycorrhizal fungi from one plot was higher because of the same soil environment and climate environment and so on, and strain type was single. Under the influence of microclimate in Northeast China, the homology of strains decreased gradually in the sample area, that is, the diversity gradually increased from the south to the north.

ABSTRACT

[Objective] To investigate the awareness rate of AIDS and STDs related knowledge, the epidemic features of high-risk behaviors and related risk factors among pregnant women in a sentinel hospital of Liangxi District of Wuxi City. [Methods]The pregnant women who built health care manual or accepted pregnancy health care from April to June in every year during 2010-2015 were investigated.[Results]Of more than 2 400 pregnant women investigated, the infection rates of HIV, syphilis, and HCV were 0.04%, 0.46% and 0.25%. The awareness rate of knowledge was 85.79%. But, the understanding of AIDS was not scientific and comprehensive. [Conclusion]The infection rates of HIV and other STDs were observed at low levels among pregnant women in the sentinel hospital of Liangxi District. But, some still had high-risk behaviors. The mastery degree of the knowledge of AIDS prevention and control were not comprehensive. Policy advocacy, health education, voluntary consultation test and many other prevention and control strategies must extend the coverage from high risk groups to pregnant women and many other general population. Intensive education about AIDS should be carried out to help people have a correct and scientific understanding of AIDS.

ABSTRACT

Glaucoma, alias'the thief of light', characterized by visual field defects that correspond to damaged areas of the optic nerve head, is a common ophthalmopathy causing irreversible blindness. Thus early diagnosis is crucial. Structural assessment can detect Glaucoma in early stage and diminish the risk of irreversible visual impairment. There are now several apparatus which can clinically measure ONH parameters and confirm DDLS (disc damage likelihood scale) precisely and reproducibly. Comprehensive estimate considering RNFLD (retina nervefiberlayer defects), offers reliable evidence as well as potent support for preclinical detecting, measurement and follow-up observations.

ABSTRACT

Objective To understand the current status of chronic disease prevention literacy among primary and secondary school students in Dalian and to provide evidence for developing health education regarding chronic diseases and promotion strategies in students. Methods A total of 1 058 students from four districts or counties in Dalian were investigated through a questionnaire survey using stratified cluster sampling in 2015. A multiple linear regression method from Stata 15. 0 was used to identify the influencing factors of chronic disease prevention literacy among primary and junior school students. Results The current status of chronic disease prevention literacy was 6. 62 % among primary and junior school students in Dalian,and it was higher in urban students than in those from rural areas (P <0. 001),higher in junior school than in primary school (P < 0. 001),and higher in girls than in boys (P = 0. 034). There also appeared to be a positive regression relationship with parents' higher education degrees (P < 0. 001). Conclusion The current status of chronic disease prevention literacy is low among primary and secondary school students in Dalian. We should strengthen their health literacy level, mobilize the role of their parents,and especially increase chronic disease prevention awareness and the self-care ability of the rural students.

ABSTRACT

Objective To compare the differences,correlation,and consistency among central corneal thickness (CCT) measurements by anterior segment optical coherence tomography (AS-OCT),Lenstar,and ultrasound biomicroscopy (UBM). Methods In this cross-sectional study,AS-OCT,Lenstar,and UBM were used to measure the CCT in 54 patients (83 eyes) between October 2015 and August 2016 in the Fourth Affiliated Hospital of China Medical University. Data were statistically analyzed by random analysis of variance, Pearson correlative analysis,and Bland-Altman analysis to compare the difference,correlation,and consistency among the three instruments. Results The differences in the mean CCT measured by the three instruments were statistically significant (P < 0. 05 for all comparisons). There was also a high correlation (all P < 0. 001) and consistency among the three instruments. Conclusion There is a high level of correlation and consistency in the CCT measurements by the three instruments. Therefore,these could be interchangeable under some circumstances. AS-OCT could be the first choice as an early screening tool for glaucoma.
