The present analysis was based on the iteration of the 2023 WHO Essential Medicines Model List(23rd list)and Essential Medicines Model List for Children(9th list).In a methodological fashion,the adjustment procedure of the basic drug list and the materials required to submit the application were sorted out.Subsequently,a comprehensive synthesis of predominant features characterizing the 2023 edition of the EML and EMLc are summarized(offered).Notably,this edition boasts the highest count of medicines ever included featuring extensive inclusion of innovative drugs to fill the gap,select medicines for children carefully,and the emphasizing on clinical benefit evidence and public health affordability.It is suggested that China should update the NEML according to the national conditions and the experience of WHO as soon as possible,pay attention to the difference and connection between the list of essential medicines and the list of medical insurance,and play a meticulous role for establishing effective linkages between two lists.Such measures are envisaged to meet the basic drug needs,and ensure the accessibility and affordability of drugs,thereby optimizing the allocation of health resources.

Objective: To investigate the risk factors for airway mucus hypersecretion in childhood pneumonia infected by different pathogens. Method: A retrospective cohort included 968 children who were hospitalized for Mycoplasma pneumoniae pneumonia (MPP), respiratory syncytial virus (RSV) pneumonia, adenovirus pneumonia and underwent bronchoscopy in Respiratory Department of Children's Hospital of Chongqing Medical University from January 2019 to December 2021 was conducted. The children were divided into two groups distinguished by airway mucus secretion according to the airway mucus hypersecretion score which were scored according to the mucus secretion under the bronchoscope. The demographic characteristics, clinical characteristics, laboratory tests and disease severity of the two groups were compared. And the risk factors for the development of airway mucus hypersecretion in two groups were analyzed. Chi square test, Mann-Whithey U test and Fisher exact test were used to analyze the differences between the two groups, and multivariate Logistic regression was used to analyze the influencing factors. Result: There were 559 males and 409 females in the 968 children, with an age of 4.0 (1.4, 6.0) years. Among the 642 children with MPP, 185 cases were in the hypersecretion group and 457 cases were in the non-hypersecretion group. There were 41 cases in the hypersecretion group and 160 cases in the non-hypersecretion group of 201 children with RSV pneumonia. In the 125 children with adenovirus pneumonia, there were 39 cases in the hypersecretion group and 86 cases in the non-hypersecretion group. In these children, the age of children in the hypersecretion group was older than that in the non-hypersecretion group (6.0 (4.0, 7.0) vs. 5.0 (3.0, 7.0) years old, 1.5 (0.5, 3.6) vs. 0.8 (0.4, 1.6) years old, 2.0 (1.2, 4.5) vs. 1.3 (0.8, 2.0) years old, U=35 295.00, 2 492.00, 1 101.00, all P<0.05). Through multivariate Logistic regression analysis it found that increased risk of airway mucus hypersecretion was present in childhood MPP with increase in peripheral blood white blood cell count (OR=3.30, 95%CI 1.51-7.93, P=0.004) or increase in neutrophil ratio (OR=2.24, 95%CI 1.16-4.33, P=0.016) or decrease in lymphocyte count (OR=3.22, 95%CI 1.66-6.31, P<0.001) or decrease in serum albumin (OR=2.00, 95%CI 1.01-3.98, P=0.047). The risk of airway mucus hypersecretion was increased in children with RSV pneumonia combined with elevated peripheral blood eosinophils (OR=3.04, 95%CI 1.02-8.93, P=0.043). Meanwhile, airway mucus hypersecretion was associated with severe pneumonia (OR=2.46, 95%CI 1.03-6.15, P=0.047) in children with RSV pneumonia. Older age was associated with increased risk of airway mucus hypersecretion in children with adenovirus pneumonia (OR=1.02, 95%CI 1.00-1.04, P=0.026). In these children with occurrence of pulmonary rales, wheezes or sputum sounds (OR=3.65, 95%CI 1.22-12.64, P=0.028) had an increased risk of airway mucus hypersecretion. Neutrophils in bronchoalveolar lavage fluid (BALF) demonstrated higher ratio in hypersecretion group from children with MPP (0.65 (0.43, 0.81) vs. 0.59 (0.34, 0.76), U=24 507.00, P<0.01), while the proportion of macrophages in BALF was lower (0.10 (0.05, 0.20) vs. 0.12 (0.06, 0.24), U=33 043.00, P<0.05). Nucleated cell count and neutrophil ratio in BALF were higher in hypersecretion group of children with RSV pneumonia (1 210 (442, 2 100)×10⁶ vs. 490 (210, 1 510)×10⁶/L, 0.43 (0.26, 0.62) vs. 0.30 (0.13, 0.52), U=2 043.00, 2 064.00, all P<0.05). Conclusions: The increase in peripheral blood white blood cell count, neutrophil ratio and decrease in lymphocyte count, serum albumin in children with MPP is related to the development of airway mucus hypersecretion. In children with RSV pneumonia, the abnormal increase of eosinophils in peripheral blood has relationship with hypersecretion. The appearance of lung rale, wheezing, and sputum rale are associated with airway mucus hypersecretion in children with adenovirus pneumonia. In addition, local neutrophil infiltration in the respiratory tract is closely related to the occurrence of airway mucus hypersecretion caused by Mycoplasma pneumoniae and RSV infection.

Aim To explore the effect of Buyang Huanwu Decoction on cerebral ischemia-reperfusion injury in rats by regulating autophagy through PI3K/AKT pathway. Methods The rats were randomly divided into five groups(n=10): sham operation group(Sham), model group(Model), Buyang Huanwu Decoction group(BYHWD), PI3K inhibitor group(LY294002)and Vehicle group(Vehicle). Except Sham group, the other groups were treated with 2h ischemia and 72 h reperfusion for modeling. The Zea Longa score was used to assess the neurological defects, HE was used to observe brain injury in the ischemic penumbra(IP), immunofluorescence was employed to detect LC3, and Western blot was used to detect pathway and autophagy marker proteins. Results Compared BYHWD group with model group, the neurological score of rats decreased, cerebral infarction volume decreased, the pathological lesions of brain IP were relieved, PI3K and p-AKT/AKT expression increased, and LC3Ⅱ/ decreased and p62 increased(P<0.05). The regulatory effect of BYHWD was weakened by LY294002(P<0.05). Conclusion Buyang Huanwu Decoction alleviates cerebral ischemia-reperfusion injury in rats by activating PI3K/AKT pathway to inhibit autophagy.

Objective:To investigate the blood pressure change in patients with acute ischemic stroke (AIS) and hypertension treated with cinepazide maleate injection.Methods:This was a subgroup analysis of post-marketing clinical confirmation study of cinepazide maleate injection for acute ischemic stroke: a randomized, double-blinded, multicenter, placebo-parallel controlled trial, which conducted in China from August 2016 to February 2019. Eligible patients fulfilled the inclusive criteria of acute anterior circulation ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores of 7-25. The primary endpoints were mean blood pressure of AIS patients treated with cinepazide maleate or control, which were assessed during the treatment period (14 days), and the proportion of the patients with normal blood pressure was analyzed after the treatment period. Furthermore, a subgroup analysis was performed to investigate a possible effect of the history of hypertension on outcomes.Results:This analysis included 809 patients with hypertension. There was no significant difference in patients blood pressure and the proportion of patients with normal blood pressure (60.5% vs. 59.0%, P>0.05) between cinepazide maleate group and control group. Conclusion:Administration of cinepazide maleate injection does not affect the management of clinical blood pressure in patients with AIS.

Objective:To explore the therapeutic effect of Fuzheng Huayu capsule on nonalcoholic fatty liver fibrosis induced by high trans fatty acid and high sugar diet in mice. Method:Forty SPF male C57/B6 mice were randomly divided into 4 groups （normal group， model group， Obelcholinic acid group， and Fuzheng Huayu capsule group）， with 10 mice in each group. Except 10 mice in the normal group， nonalcoholic fatty liver fibrosis was induced by high-fat and high-sugar diet for 24 weeks in the other 30 mice. From the 25th week of modeling， 4 groups received intragastric administration for 4 weeks， once a day： Fuzheng Huayu capsule group 4.8 g·kg^-1. Oxycholic acid group 10 mg·kg^-1. Model control group and normal group received the same volume of normal saline. Liver tissue and serum samples were collected at the end of the 28th week. The pathological changes of liver tissue of mice in each group were observed by hematoxylin-eosin （HE） staining， the degree of liver fibrosis was observed by Sirius red staining， the degree of lipid deposition was observed by oil red O staining， the content of hydroxypropylamine （Hyp） in liver tissue was determined by alkaline hydrolysis， and the change of triglyceride （TG） in liver tissue was detected by enzyme method. Serum alanine aminotransferase （ALT）， aspartate aminotransferase （AST） activities and fasting blood glucose （FBG） were detected by kit method， enzyme-linked immunosorbent assay （ELISA） was used to detect fasting Insulin （INS） level and calculate the changes of insulin resistance index （HOMA-IR）， liver fibrosis related mRNA and proteins of were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， Western blot and Immunohistochemistry. Result:Compared with the normal group， the liver tissue in the model group showed significant collagen fiber deposition， at mostly F2-F3 fibrosis stages， with increased number of inflammatory foci in liver tissue， obvious balloon degeneration and fatty degeneration of liver cells， significantly increased contents of Hyp and TG in liver tissue （P<0.01）， significantly increased activities of ALT and AST in serum and levels of FBG， INS and HOMA-IR （P<0.01）， and increased type I collagen （Col-Ⅰ）， Col-Ⅳ， α-smooth muscle agonist protein （α-SMA） and transforming growth factor-β （TGF-β） protein and mRNA in liver tissue. Compared with the model group， the collagen fiber deposition in liver tissue of mice in Fuzheng Huayu capsule group was significantly reduced， at mostly F0-F1 fibrosis stages， with significantly improved balloon-like change of hepatocytes， and significantly reduced number of inflammatory foci in lobules （P<0.05，P<0.01）. Compared with the model group， Fuzheng Huayu capsule can significantly reduce the content of Hyp in liver tissue， the levels of serum ALT and AST， and the expression of Col-Ⅰ， Col-Ⅳ， α-SMA and TGF-β genes and proteins in mice （P<0.05，P<0.01）. Conclusion:Fuzheng Huayu capsule has a good therapeutic effect on nonalcoholic fatty liver fibrosis induced by high trans fatty acid and high sugar diet in mice.

Primary liver cancer (PLC) is one of the most common malignant tumors in China. PLC is characterized by insidious onset, rapid progress, poor quality of life, and short survival time. Notably, current treatment strategies remain unsatisfactory. Traditional Chinese medicines (TCM) have been used to treat a variety of diseases, including liver diseases, for more than 2000 years. In this study, we performed a review of the use frequency and clinical efficacy of TCM in treating PLC. Relevant literature from January 1, 2009, to January 1, 2021 was retrieved from network databases of China National Knowledge Infrastructure (CNKI), Chongqing VIP, Wanfang, PubMed, and SinoMed. The most frequently used TCM and their effi-cacy in PLC treatment were summarized. Based on the inclusion and exclusion criteria, 33 articles were selected. Overall, the efficacy of the combination of TCM and Western medicines in the treatment of PLC was higher than that in the control groups (i.e. treatment with Western medicines alone) (65.11％ vs. 44.31％, P < .05). Among the 33 selected articles, 11 were investigated for TCM preparation (marketed drugs) and 22 for TCM formulas. In total, 102 types of TCM (single herbs) were used to treat PLC. The top five most frequently used TCM were Poria (14.71％), Astragali radix (13.73％), Atractylodis Macrocephalae Rhizoma (12.75％), Bupleuri radix (12.75％), and Glycyrrhizae radix et Rhizoma (11.76％). Of the 102 types of TCM, tonics were the most frequently used categories, followed by heat-clearing medicines, blood-invigorating medicines, and stasis-resolving medicines. Of 207 papers, 174 (84.06％) could not be sub-jected to statistical analysis due to research quality. Further high-quality research on herb sources, for-mula components and dosage, toxicology, and ethics of TCM is necessary. In conclusion, TCM play a promising role in the treatment and management of PLC, although further investigations are warranted.
