ABSTRACT

Objective:To explore application of mixed teaching platform in the clinical practice teaching of the laboratory medicine in Children's hospitals.Methods:We constructed a mixed online and offline teaching platform based on the Laboratory Quality Management System (LQMS) in the Children's Hospital of Chongqing Medical University. The undergraduates from Batch 2016 ( n=15) and Batch 2018 ( n=12) of College of Laboratory Medicine of Chongqing Medical University were taken as control group and experimental group respectively. Traditional teaching method was adopted by the control group, and the mixed teaching method was adopted by the experimental group. The results of two groups' clinical practice assessment, rate of outstanding students (total score ≥ 90) and rate of satisfaction (score ≥ 90) were compared to evaluate the teaching effect. SPSS 17.0 was used to conduct t-test and Chi-square test. Results:The database of teaching platform includes 68 teaching cases, 198 pieces of courseware, 305 clinical cases and 3 036 atlases. The test bank has accumulated 4 657 tests, covering clinical laboratory, immunology, biochemistry, microbiology and blood transfusion. The results of students in experimental group were significantly better than those of the control group [the score of clinical practice assessment: (85.90±5.04) vs. (78.90±6.75)( P<0.05); rate of outstanding students: 33.3% (4/12) vs. 6.7% (1/15), P>0.05; rate of satisfaction: 86.7% (13/15) vs. 100.0% (12/12) ( P>0.05). Conclusion:The mixed online and offline teaching platform based on the LQMS is highly recognized by students and can significantly improve the effect of clinical practice teaching, which can provide typical medical case teaching at any time and make up for limited case type in children's hospital.

ABSTRACT

Objective: To evaluate the relationship between red blood cell folate (RBC folate) and the prognosis of low-grade cervical intraepithelial neoplasia (CIN 1). Methods: In the married women cohort established in 2014, 564 women with CIN 1 diagnosed by pathology were recruited. The demographic characteristics and factors of cervical intraepithelial neoplasia were collected. Meanwhile, the infection status of human papillomavirus (HPV) was detected by molecular diversion hybridization, and the level of RBC folate was measured by chemical photoimmunoassay. After 24 months of follow-up, pathological examination was performed again to observe the prognosis of participants. The women with reversal were taken as the control group,and those with continuous and progressive CIN 1 were taken as the case group respectively. The relationship between RBC folate and CIN 1 outcome was evaluated by logistic regression model. Results: 453 women completed the follow-up, aged (49.72±6.84) years old. CIN 1 was reversed in 342 women, continued in 58 cases and progressed in 53 cases. The RBC folate level M (Q1,Q3) were 399.01 (307.10, 538.97) ng/ml, 316.98 (184.74, 428.49) ng/ml and 247.14 (170.54, 348.97) ng/ml, respectively. With the decrease of RBC folate, the risk of continuous and progressive CIN 1 increased (all P<0.001), while the risk of reversal CIN 1 decreased gradually (P<0.001). Combined with high-risk human papillomavirus (HR-HPV) infection status, low level of RBC folate could increase the risk of CIN 1 progression regardless of HR-HPV infection (HR-HPV infection: OR=21.34, 95%CI: 3.98-114.54; HR-HPV uninfection: OR=11.15, 95%CI: 2.34-53.13). Conclusion: Low level of RBC folate could increase the risk of CIN 1 persistence and progression regardless of HR-HPV infection.

ABSTRACT

Objective To analyze and compare the epidemiological characteristics of imported malaria in Jiaozuo City before and after malaria elimination, so as to provide insights into the malaria surveillance during the post-elimination stage and prevention of re-establishment of imported malaria. Methods Data pertaining to the epidemic situation and individual investigation of malaria in Jiaozuo City before (from 2010 to 2016) and after malaria elimination (from 2017 to November, 2020) were captured from the National Notifiable Disease Reporting System and the Information System for Parasitic Diseases Control and Prevention of Chinese Center for Disease Control and Prevention and were analyzed statistically. Results A total of 74 imported malaria cases were reported in Jiaozuo City from 2010 to 2021. Imported cases were predominantly Plasmodium falciparum malaria cases in Jiaozuo City before and after malaria elimination, and there was no significant difference in the proportion of malaria parasite species (χ2 = 0.234, P > 0.05). The imported malaria cases was predominantly reported in Wuzhi County, and was identified in overseas male farmers and businessmen at ages of 20 to 59 years, while the greatest number of imported malaria cases was reported in June and December before and after malaria elimination. The imported malaria cases predominantly acquired malaria parasite infections in sub-Saharan African countries; however, the proportion of imported malaria cases returning from Southeast Asian counties increased after malaria elimination than before malaria elimination (χ2 = 5.989, P < 0.05). The longest duration from onset to definitive diagnosis of malaria reduced from 27 days before malaria elimination to 18 days after malaria elimination, and the median duration reduced from 3 days to 2 days, while the proportion of definitive diagnosis of malaria increased from 60.47% before malaria elimination to 83.87% after malaria elimination (χ2 = 4.724, P < 0.05). In addition, the proportion of malaria cases definitively diagnosed and reported by medical institutions increased after malaria elimination than before malaria elimination (χ2 = 5.406, P < 0.05). Conclusions The imported malaria patients were predominantly P. falciparum malaria cases in Jiaozuo City during 2010 to 2021, and the patient’s medical care-seeking awareness and medical staff’s diagnosis and treatment ability have improved after malaria elimination. It is necessary to strengthen and improve malaria surveillance and response system and prevent the re-establishment of overseas imported malaria.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the clinical efficacy of self-made Kirschner wire hook in the treatment of severely displaced proximal humerus fractures in children.</p><p><b>METHODS</b>From January 2007 to February 2012,35 children with severely displaced proximal humerus fractures were treated with self-made Kirschner wire hook fixation,including 25 boys and 10 girls with an average age of 13.2 years old ranging from 5 to 17. The duration from injury to operation was 1 to 10 days with an average of 4.5 days. Preoperative diagnoses were confirmed by X-ray films as type III in 26 cases and type IV in 9 according to the Neer-Horwitz classification of the proximal humerus fractures. All fractures were close fracture without nerve or vascular injuries. Anatomical reduction was achieved by open reduction and the fractures were fixed by self-made Kirschner wire hook. Intra-operative and postoperative complications, postoperative radiographic examination, upper extremity length and range of shoulder motion were observed and recorded. Neer score system was used to evaluate shoulder function.</p><p><b>RESULTS</b>All patients were followed up from 6 to 18 months with an average of 12.1 months. The mean Neer score of the injured side was 94.2 +/- 4.8 (ranged, 84 to 99), 30 patients got an excellent result and 5 good according to the Neer scores. The X-ray showed all the fractures healed without shortening deformity or epiphyseal arrest at early stage. There were no complications related to the implant including loosening or breakage of the self-made Kirschner wire hook. The range of shoulder motion in the injuried side was similar to the normal side, except in abductor lift. All the patients could participate in normal physical activities.</p><p><b>CONCLUSION</b>The method of open reduction and fixed with self-made Kirschner wire hook is a safe,effective,convenient treatment for severely displaced proximal humeral fractures in children.</p>
