Study on the physical growth status of birthweight discordant twins under 4 years old / 中国实用儿科杂志

OBJECTIVE: To study the physical growth characteristics of birthweight discordant twins(BDT)under 4 years old. METHODS: The physical growth characteristics of BDT under 4 years old born from September 2010 to December 2017 in child health care system of Children's Hospital of Chongqing Medical University were analyzed retrospectively. R 3.5.3 was used to clean up the database,analyze the distribution of different degree of birthweight discordance,and draw the fitting curves. More than 20% of birth weight difference was taken as inclusive criteria of BDT. BDT were divided into preterm or full-term groups,and low birthweight or normal birthweight groups respectively. SPSS 19.0 software was used for statistical analysis. RESULTS: A total of 141 pairs of BDT were included,accounting for 15.4%(141/916). The degree of birthweight difference in premature BDT was higher than that of full-term BDT(t=3.820,P<0.001). The growth discordance of preterm BDT lasted longer. Physical growth of low/very low birthweight BDT was slower than that of normal birthweight BDT under 4 years old. The growth status of BDT didn't reach the average level of WHO growth chart by the time of the last follow-up. CONCLUSION: Birthweight discordance of twins could have longlasting effects on further growth and development. Preterm twins have higher degree of birthweight discordance,and the growth discordance lasts longer. Low birthweight is an important reason for growth retardation of the lighter BDT.Growth of BDT should be monitored regularly to increase follow-up compliance.

Current situation and related factors of AIDS discrimination among junior medical students in Jiangxi Province / 中国学校卫生

Objective@#To explore the current situation and related factors of AIDS discrimination among junior medical students in Jiangxi Province, so as to provide a reference for effective AIDS anti discrimination intervention measures in medical colleges.@*Methods@#Using a convenience sampling approach, 2 484 medical students were selected from five universities in Jiangxi Province from July to August 2023. An anonymous survey was conducted using a general information questionnaire, a AIDS knowledge questionnaire, and the Chinese version of Zelaya s AIDS Stigma Scale. Independent sample t-tests and analysis of variance were carried out to analyze the level of AIDS discrimination among medical students with different characteristics. Multiple stepwise regression analysis was performed to identify the related factors of AIDS discrimination.@*Results@#The total score of AIDS discrimination among medical students was (2.55±0.67). The dimension with the highest score was fear of contracting the disease (2.89±1.01). The results of the multiple stepwise regression analysis showed that the factors related to AIDS discrimination included gender ( β = -0.17 ), grade ( β =-0.08), being an only child or not ( β =-0.04), whether knowing about AIDS knowledge or not ( β =0.22), willingness to use condoms during sexual activity ( β =0.07), willingness to participate in school sexual health knowledge based activities ( β =0.05) and the perceived importance of selfhealth ( β =0.11) ( P <0.05).@*Conclusions@#AIDS discrimination is prevalent among junior medical students in Jiangxi Province. Efforts should be undertaken to enhance humanistic education and relevant knowledge dissemination among junior medical students to reduce the level of AIDS discrimination.

Quantitative evaluation of Colles' fracture by Multislice CT multiplanner reconstruction: a feasibility study / 中国骨伤

<p><b>OBJECTIVE</b>To investigate the feasibility and reliability on the quantitative evaluation of Colles' fracture by multislice CT (MSCT) multiplanner reconstruction (MPR).</p><p><b>METHODS</b>A total of 36 patients with Colles' fracture from July 2011 to July 2014 were investigated in this study. There were 11 males and 25 females with a mean age of (42.5 ± 5.4) years old (ranged 35 to 72 years). All the patients underwent anteroposterior and lateral X-ray films and MSCT scans on wrist joints within 2 days after trauma. Images were sent to the workstation through picture archiving and conserving system (PACS). One associate chief physician independently and respectively measured the dorsal intercalation depth of distal fracture block, palmar angle and dislocation degree of wrist articular surface collapse on anteroposterior and lateral X-ray film and MSCT-MPR. The time interval between the two measurements was 2 weeks. All the data between the first and second measurement on X-ray and MPR and the mean value between the X-ray and MPR was examined with paired t-test. The pearson analyzed their correlation.</p><p><b>RESULTS</b>Among the 35 cases, 35 cases of palmar angle, 21 cases of intercalation depth and 16 cases of dislocation of wrist articular surface collapse could be measured on both X-ray and MPR. For the above parameters, the first measurement results were (12.5 ± 3.6)°, (4.5 ± 2.1) mm, (3.7 ± 1.6) mm and the second measurement results were (4.8 ± 2.2)°, (6.4 ± 3.6) mm, (2.5 ± 1.2) mm on X-ray films respectively. The first measurement results on MPR were (14.5 ± 5.3)°, (4.2 ± 1.2) mm, (5.7 ± 2.3) mm, and the results were (13.2 ± 2.6)°, (4.7 ± 2.2) mm, (4.6 ± 2.1) mm for the second measurement respectively. The three parameters between the first and second measurement on plain film had statistical difference and low correlation (r = 0.681, 0.640, 0.345, P < 0.05). The data between the first and second measurement on MPR showed that the dislocation degree of wrist articular surface collapse had statistical difference (P < 0.05) and no statistical significance was found for the other two parameters (P > 0.05), with the moderate correlation (r = 0.954, 0.854, 0.642). The three parameters had low or moderate correlation with each other on X-ray (r = 0.454, 0.532, 0.378, P < 0.05), compared with the mean value on MPR.</p><p><b>CONCLUSION</b>Using MSCT MPR images may carry on the multiple parameter measurement of Colles fracture, to make quantitative evaluation, and repeated measurement is better reliability.</p>

Clinical Significance of Plasma D-dimer in Systemic Sclerosis / 现代检验医学杂志

Objective To study correlation between systemic sclerosis(SSc)and plasma D-dimer and to reveal the probably rules of the fibrinolytic systems in SSc.Methods In 2013 January to 2014 January,cellected 32 patients with SSc and 35 with healthy controls to detected level of plasma D-dimer.Logistic and t student test were used for statistical analysis for correlation between SSc and pulmonary artery hypertension.Results When compared to healthy controls (0.28±0.04μg/ml),the level of plasma D-dimer were significantly increased in SSc patient (0.31±0.05μg/ml,t=1.997,P=0.008).After stratifying SSc patients according to disease subset,whereas patients with diffuse subset displayed substantially increased values (0.41±0.06μg/ml,t=2.051,P<0.001).The level of plasma D-dimer was associated with pulmonary artery hyper-tension (OR=4.38,95%CI=2.59~8.91,P=0.008).Conclusion Demonstrated that SSc patients with diffuse subset are characterized by increased plasma D-dimer values,reflecting a potential activation of fibrinolytic cascaded,which might finally predispose these patients to thrombotic complications and pulmonary artery hypertension.

Evaluation of Several Inflammatory Markers to Infectious and Gouty Arthritis / 现代检验医学杂志

Objective The aim of this study was to investigate which inflammatory markers allow an accurate differentiation of septic and gouty arthritis.Methods In 2013 January to 2014 January 33 patients with septic arthritis and 29 patients with gouty arthritis.Detected white blood cells,C-reactive protein and uric acid of inflammatory markers in plasma and tested lac-tate,glucose,uric acid,lactate dehydrogenase and white blood cell count inflammatory markers in the synovial fluid.MedCalc 13.0 software were used for statistical analysis.Results There were no significantly different between serum C-reaction protein and WBC counts with two groups.Synovial lactate showed the greatest diagnostic potential (AUC=0.898,sensitivi-ty=96.9%,specificity=72.4%)followed by serum uric acid (AUC=0.818)and synovial uric acid (AUC=0.808).Con-clusion Lactate in the synovial fluid has excellent diagnostic potential to differ septic arthritis from gouty arthritis.Synovial lactate levers above 1.7 mmol/L almost proofed septic arthritis.
