Clinical efficacy of magnetotherapy combined with pediatric massage on infantile colic.

OBJECTIVE: To investigate the short-term and long-term efficacy of magnetotherapy and pediatric massage in the treatment of infantile colic. METHODS: A total of 120 neonates with sudden onset crying, bloating, and breast refusal who met the diagnostic criteria for colic were retrospectively enrolled from September 2019 to September 2021. They were divided into a combination group, a magnetotherapy group, a pediatric massage group, and a control group based on different treatment methods (n=30 in each group). All cases were provided with conventional nursing. RESULTS: The short-term efficacy of the combination group was significantly better than that of the control group. The difference was not statistically significant among combination, magnetotherapy, and pediatric massage groups (P>0.05). In the long-term efficacy assessment, the total effective rate was 96.67% in the combination group, 93.33% in the magnetotherapy group, 86.67% in the pediatric massage group, and 93.33% in the control group. There was no significant difference among the groups (P>0.05). Neonates in the combination group had the shortest crying relief time and the longest sleep duration after relief. This was followed by the magnetotherapy and the pediatric massage groups (P<0.05). Neonates in the control group had longer crying relief time and shorter sleep duration after relief than those in the combination group (P<0.05). From day 2 to day 7 of intervention, the pain level of the combination group was decreased significantly. This was significantly lower than that of the control group (P<0.05). CONCLUSION: Magnetotherapy combined with pediatric massage can improve neonatal colic, relieve crying and pain symptoms, and improve sleep quality.

The Development and Application of Virtual Reality Animation Simulation Technology: Take Gastroscopy Simulation System as an Example.

Virtual reality (VR) technology has a great potential in the field of medical simulation due to its immersion, interactivity and autonomy. It provides a new direction for integration and application in various disciplines. Combination of VR technology and clinical practice brings great convenience for medical education and experiments. Modern VR simulators can create realistic environments that capture minute anatomical details with high accuracy and solves the problem of difficulty in mass productions with traditional devices. Taking gastroscopy simulation system as an example, this paper discusses the development and application of VR animation technology, together with its excellent performance and current research status in surgery, scientific research, training and education.

Comparative analysis of the complete chloroplast genomes of seven Populus species: Insights into alternative female parents of Populus tomentosa.

Populus tomentosa, of section Populus, is distributed mainly in northern China. This species has high resistance to many diseases and insects, and it plays key roles in shelterbelts and urban afforestation in northern China. It has long been suspected to be a hybrid, but its parents remain unknown. In the present study, we report four newly sequenced complete cp genomes from section Populus and comparative genomic analyses of these new sequences and three published cp genome sequences. The seven cp genomes ranged from 155,853 bp (P. tremula var. davidiana) to 156,746 bp (P. adenopoda) in length, and their gene orders, gene numbers and GC contents were similar. We analyzed SNPs, indels, SSRs and repeats among the seven cp genomes, and eight small inversions were detected in the ndhC-trnV, rbcL-accD, petA-psbJ, trnW-trnP, rpl16-rps3, trnL-ycf15, ycf15-trnL, and ndhF-trnL intergenic regions. Furthermore, seven divergent regions (trnH-psbA, matK, psbM-psbD, ndhC-trnV, ycf1, ndhF-ccsA and ccsA-ndhD) were found in more highly variable regions. The phylogenetic tree reveals that P. tomentosa is closely related to P. alba and P. alba var. pyramidalis. Hence, P. alba was involved in the formation of P. tomentosa.

[Traditional Chinese medicine syndrome factors of patients with HIV infection or AIDS in China].

OBJECTIVE: To study the characteristics of traditional Chinese medicine (TCM) syndrome factors of patients from different areas of China with human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS). METHODS: A cross-sectional investigation study was conducted in Henan, Guangdong and Yunnan Provinces and Xinjiang Uygur Autonomous Region of China from October 2008 to August 2010. Based on literature review and expert opinion, a clinical questionnaire of TCM syndromes was drawn up. This survey was carried out after the investigators were professionally trained. Wenfeng III Auxiliary Diagnosis and Treat System of TCM was used to analyze the frequencies of AIDS patients' signs and symptoms with scores above 70 of syndrome factors respectively. Based on this work, syndrome factors of AIDS were analyzed in different areas. RESULTS: There were 608 HIV/AIDS cases investigated from October 2008 to August 2010 in total; among them, 276 cases were from Henan, 126 cases from Guangdong, 120 cases from Xinjiang and 86 cases from Yunnan. The results of syndrome factor analysis indicated that the syndromes of four provinces were similar. HIV/AIDS patients in the four areas exhibited qi deficiency, blood deficiency, yin deficiency, yang deficiency, dampness, phlegm, qi stagnation and essence deficiency syndromes. Patients in each area also had their own characteristics, such as that the scores of dampness of Guangdong and yin deficiency of Xinjiang were higher than the other syndromes, whereas the scores of Henan Province were higher than the other areas. AIDS patients had higher scores of syndromes than HIV-infected patients. CONCLUSION: HIV/AIDS patients from different areas had similar syndrome elements. The theory of "AIDS toxin injuring primordial qi" can sum up the TCM etiology and pathogenesis of HIV/AIDS.
