Objective To detect expression of miR-106a-5p in gastric cancer cells and gastric cancer tissue, and to analyze relationship between it’s expression with clinicopathologic characteristics, and in addition, to analyze its target genes and enriched pathway with bioinformatics method. Methods The expressions of miR-106a-5p in the different differentiation of gastric cancer cells AGS (well differentiation), MKN-28 (middle differentiation), HGC-27 (undifferentiation), MGC-803 (low differentiation), BGC-823 (low differentiation), MKN-45 (middle differentiation) and SGC-7901 (middle differentiation), the normal gastric mucosal epithelial cells GES-1, and the gastric cancer tissue and the corresponding adjacent tissue were detected by the real-time fluorescent quantitative PCR. Furthermore, the target genes of miR-106a-5p were predicted by using more than three softwares affiliated to mirWALK web database and the signal pathways of target genes were enriched by DAVID 6.7 software. Results The expressions of miR-106a-5p in the different differentiation degree of the gastric cancer cells (AGS, SGC-7901, MKN-45, MGC-803, BGC-823, and HGC-27) were up-regulated except the MKN-28 cell line as compared with the normal gastric mucosa cell line GES-1 (P<0.010 orP<0.001), and the expression of miR-106a-5p in the gastric cancer tissue was also up-regulated as compared with the corresponding adjacent tissue, the expression of miR-106a-5p in the gastric cancer tissue was associated with the lymph node metastasis or the invasion depth. The results of the bioinformatics analysis showed that the target genes of miR-106a-5p were enriched in the multiple signaling pathways associated with the cancer. Conclusion miR-106a-5p is a molecular marker of high expression in gastric cancer and a potential cancer gene associated with lymph node metastasis and invasion depth.
ObjectiveTo observe the expressions of miR-143-3p in gastric cancer cells and gastric carcinoma tissues with its clinical significance, and to analyze the target genes with enriched pathway by using bioinformatics methods.MethodsThe expressions of miR-143-3p in different differentiation gastric cancer cells and normal gastric mucosa cell line, and the expressions in gastric cancer tissues and adjacent tissues were detected by real-time fluorescent quantitative PCR. In addition, OncomiR and YM500 databases were used to analyze the expression of miR-143-3p in gastric cancer tissues compared with adjacent tissues. Furthermore, the targets of miR-143-3p were predicted by using the software of miRecords website database, and at least three software-supported target genes were chosen to analyze the enriched the signal pathways in which the target gene was involved with DAVID 6.7 software.ResultsThe expressions of miR-143-3p in the different differentiation degree of gastric cancer cells compared with normal gastric mucosa cell line were downregulated (P<0.001), and the expression of miR-143-3p in gastric cancer tissues compared with adjacent tissues was also downregulated (downregulated in 36 cases, upregulated in 18 cases, and no alteration in 4 cases). The expression of miR-143-3p in gastric cancer tissues was associated with lymph node metastasis and invasion depth (P<0.05). Bioinformatics analysis results showed that the target genes of miR-143-3p were enriched in 38 signaling pathways associated with cancer.ConclusionMiR-143-3p is a down-regulated molecular marker in gastric cancer and a potentially clinically related tumor suppressor gene, which may be involved in the cancerous phenotype in carcinogenesis and development of gastric cancer.
Objective To compare the costs of Danmu extract syrup and Xiaoer Chiqiao Qingre granules for the treatment of acute upper respiratory tract infection (AURI) in children. Methods We conducted this prospective cohort study from July 2018 to June 2020. Children with AURI in the pediatric outpatient department and emergency department of West China Second Hospital were enrolled, and were divided into two groups: Danmu extract syrup group (Danmu group) and Xiaoer Chiqiao Qingre granule group (Chiqiao group) according to the treatment. The pharmacoeconomic evaluation took the medical and health system as the research perspective and considered direct medical costs, including registration fees, drug fees, inspection fees, testing fees, and treatment fees. A cost-effectiveness analysis or a cost minimization analysis was adopted according to the results of efficacy between the two groups. Results We enrolled 1 036 children with AURI. After propensity score matching, 252 in the Danmu group and 253 in the Chiqiao group were included. There was no statistically significant difference in the symptom recovery time between the two groups. The cost minimization analysis showed that the total costs (median difference −21.55) and drug costs (median difference −7.24) of the Danmu group were significantly lower than those of the Chiqiao group (P<0.001). The results of the subgroup and sensitivity analyses were consistent with the primary analysis. Conclusion Danmu extract syrup is a cost-saving alternative compared with Chiqiao granules for AURI in children.
Objective To analyze and compare the urban-rural difference of health resource allocation of maternal and child health institutions in Sichuan province. MethodsGini coefficient and agglomeration degree was used to analyze the equity of health resource allocation of maternal and child health institutions in Sichuan province. ResultsThe number of maternal and child health institutions per 10 000 population in rural areas was higher than that in urban areas, while the hospital beds and health workers per 10 000 population was lower. In terms of population-based Gini coefficient, the value of three type of health resources of maternal and child health institutions in Sichuan Province were lower than 0.4, indicating a good equity, however, the value of institutions and health workers in urban areas were lower than those in rural areas, the value of hospital beds were higher than those in rural areas. In terms of the difference between HRAD and PAD, there were great differences in the population-based accessibility of health resources of maternal and child health institutions in Sichuan province, relative excess and relative deficiency coexisted in different city (state). Moreover, there were differences in population-based accessibility to health resources of maternal and child health institutions between urban and rural areas in each city (state). ConclusionThere are obvious urban-rural and regional differences in health resources allocation of maternal and child health institutions in Sichuan province. Social factors such as population, geographical area and service radius should be comprehensively considered according to the real needs in the planning of rational health resources allocation of maternal and child health institutions.

ObjectiveTo systematically review the classification system for the causes of pediatric drug shortages in China, and classify the causes of pediatric drug shortages accurately, so as to provide references for the formulation of targeted strategies. MethodsFour databases including Embase, PubMed, CBM and CNKI were searched from inception to November 2023. Quantitative research, qualitative research and mixed-method research on the causes of pediatric drug shortages in China were included. Two researchers independently screened the literature and extracted data. Based on the theory of efficient market and effective government, and according to the life cycle of the drug supply chain, the fundamental causes of drug shortages were classified and summarized by thematic synthesis. ResultsFourteen articles were included. According to the four stages of the drug supply chain (research and development, production, circulation and use), a total of 19 categories of causes of the pediatric drug shortages were summarized, including 5 categories in the research and development stage, 4 categories in the production stage, 6 categories in the circulation stage, and 4 categories in the use stage. Based on the theory of efficient market and effective government, further analysis of the causes revealed that the identified reasons could be attributed to three major fundamental causes: market failure, government failure, and other causes. Among them, 6 categories were related to market failure, 7 categories were related to government failure, and 6 categories were classified as other causes. ConclusionBased on the theory of efficient market and effective government, this study established a classification system of fundamental causes of the pediatric drug shortages, and made policy suggestions accordingly. Subsequently, the classification system established in this study can be used as references to develop targeted strategies to solve the problem of pediatric drug shortages in the life cycle of drug supply chain from government and market perspectives.

Objective To update and form an instrument for evaluating clinical applicability of guidelines (version 1.0). Methods We updated the systematic review of global guideline clinical applicability evaluation instruments to form the initial item list and carried out Delphi expert consultation to establish the instrument for evaluating clinical applicability of guidelines (version 2.0). Results The general structure of version 2.0 was consistent with that of version 1.0, which included 12 evaluation items belonging to five domains covering accessibility, readability, acceptability, feasibility, and an overall evaluation. Moreover, some new items were added in version 2.0, such as "The guideline does not provide supporting tools or resources and the operation is poor", "After the guideline implementation, the expected effects of diagnosis and treatment do not be achieved", " Medical staff in your workplace believe that the guideline is not necessary because they have sufficient medical experience, etc.", "Lack of authority of the organizations and personnel that developed the guideline" and "Medical staff in your workplace are reluctant to change the original medical practice". Conclusion This study updated and formed an instrument for evaluating clinical applicability of guidelines (version 2.0), which is able to better assess the applicability of new clinical guidelines and greatly promote more appropriate guidelines into practice.
ObjectiveTo evaluate the efficacy, safety, and economics of omalizumab for the treatment of pediatric asthma through a rapid health technology assessment (HTA). MethodsThe search was conducted on INAHTA website and databases such as PubMed, Embase, Cochrane Library, SinoMed, CNKI, VIP, and WanFang Data from inception to August 2024. Literature screening, quality evaluation, and data extraction were conducted independently by two investigators. An interview was conducted to consult the medication and treatment opinions of doctors and patients to investigate its clinical application. ResultsA total of 28 articles, including HTA articles (4), SR/Meta analyses (18), and pharmacoeconomics articles (6) were included. Omalizumab could reduce the incidence of clinical exacerbations, decrease the number of asthma attacks/days with asthma symptoms, and improve the quality of life. The results of the safety evaluation showed that omalizumab could reduce the rate of serious adverse events, especially those related to worsening asthma. Foreign pharmacoeconomic studies showed ICER ranging from £30 109 to £78 009. A pharmacoeconomic study in China found an ICER of $211 217/QALY for omalizumab, which were both above the pre-set thresholds. ConclusionOmalizumab is a treatment for patients who suffer from moderate to severe persistent allergic asthma or moderate to severe allergic asthma. It has been found to improve disease symptoms without increasing serious adverse events. However, it is not considered cost-effective due to its high price.
