OBJECTIVE To provide technical support for improving recognition rate of adverse drug events （ADEs） related to traditional Chinese medicine （TCM） formula granules and decoction pieces among inpatient patients. METHODS By referencing the global trigger tool （GTT） whitepaper， literature on adverse reactions to TCM， and expert review opinions， ADE trigger items for TCM formula granules and decoction pieces used in the inpatients were established. GTT was applied to analyze ADEs in inpatients who had used TCM formula granules and decoction pieces in our hospital from August 2013 to August 2023， utilizing the Chinese Hospital Pharmacovigilance System. The effectiveness of GTT and the characteristics of these ADEs were analyzed. RESULTS A total of forty-eight triggers were established， including thirty-two laboratory test indexes， thirteen clinical symptoms， and three antidotes. Among the 1 682 patients included， GTT identified 652 potential ADEs， 284 true positive ADEs，with a trigger rate of 38.76% and a positive predictive value of 43.56%. After review by the auditor， 278 cases of ADEs were finally confirmed， with an incidence rate of 16.53%， significantly higher than the number of spontaneously reported ADEs during the same period （0）. The 278 cases of ADEs were mostly grade 1 （223 cases）， mainly involving hepatobiliary system， gastrointestinal system， blood- lymphatic system， etc；a total of 219 types of TCMs are involved，and the top five suspected TCMs used at a frequency higher than 1% were Poria cocos， Codonopsis pilosula， Atractylodes macrocephala， fried Glycyrrhiza uralensis， and Scutellaria baicalensis. CONCLUSIONS The established GTT can improve the recognition rate of ADEs for hospitalized patients using traditional Chinese medicine formula granules and decoction pieces.

OBJECTIVE To investigate the effects of peiminine B （PEI） on Streptococcus pneumoniae （SP）-induced alveolar epithelial cell injury by regulating the Ras-related C3 botulinum toxin substrate 1 in nucleus accumbens （Rac1）/protein kinase B （Akt）/nuclear factor κB （NF-κB） signaling pathway. METHODS Human alveolar epithelial cells （HPAEpiC） were taken and randomly divided into the Control group， SP group （1×108 cfu/mL SP bacterial solution）， low-， medium-， and high-concentration PEI groups （1×108 cfu/mL SP bacterial solution+0.05， 0.10， 0.20 mmol/L PEI）， and high-concentration PEI+Akt activator group （P-H+SC79 group， 1×108 cfu/mL SP bacterial solution+0.20 mmol/L PEI+10 μmol/L SC79）. Except for the Control group， the other groups of cells were treated with SP bacterial solution and/or corresponding drug solution. After 24 h of treatment， the levels of inflammatory factors （interleukin-6， -18， -1β） in the supernatant solution， the contents of oxidative stress indexes [lactate dehydrogenase （LDH）， reactive oxygen species （ROS） and superoxide dismutase （SOD）]， apoptosis rate， as well as the expressions of proliferation/apoptosis-related proteins [cyclin-dependent kinase 1 （CDK1）， B cell lymphoma-2 related X protein （Bax）] and pathway-related proteins （Rac1， Akt， phosphorylated Akt， NF-κB and phosphorylated NF-κB） were detected in each group. RESULTS Compared with the Control group， the levels of inflammatory factors in supernatant solution， LDH and ROS contents， apoptosis rate， the protein expressions of Bax and Rac1 and the phosphorylation levels of Akt and NF-κB in the SP group were significantly increased or up-regulated， while SOD content and the protein expression of CDK1 were significantly decreased or down-regulated （P＜0.05）. Compared with the SP group， the above indexes in PEI groups were significantly improved in a concentration-dependent manner （P＜0.05）. SC79 could significantly reverse the improvement effect of the high concentration of PEI （P＜0.05）. CONCLUSIONS PEI can alleviate SP-induced inflammation and oxidative stress damage of alveolar epithelial cells and inhibit apoptosis， which may be achieved by inhibiting Rac1/Akt/NF-κB signaling pathway.

Objective To analyze the status of persistent human papillomavirus (HPV) infection and the distribution of viral subtypes in the Zhengzhou region. Methods Clinical data of 55239 patients who underwent HPV-DNA genotyping tests from 2018 to 2024 were collected. On the basis of HPV follow-up results, patients were divided into three groups: 849 cases of infection with the same HPV type, 255 cases of persistent infection with different HPV types, and 857 cases of transient HPV infection. Results Among the 9232 initially-screened patients who were positive with HPV, the high-risk HPV (HR-HPV) positive rate was 84.6% (7813/9232), and predominant subtypes were HPV-16 (20.8%), HPV-52 (17.2%), and HPV-53 (9.6%). The low-risk HPV (LR-HPV) positive rate was 15.4% (1419/9232), mainly HPV-81 (28.1%) and HPV-42 (27.0%). Among the 1961 follow-up cases, the rates of persistent and non-persistent infections with the same HPV type were 35.7% (701/1961) and 7.5% (148/1961), respectively. The rates of persistent and non-persistent infections with different HPV types were 10.9% (214/1961) and 2.1% (41/1961), respectively. Meanwhile, 43.7% (857/1961) tested negative upon follow-up. Among the 701 cases of persistent infection with the same HPV type, HR-HPV accounted for 85.7% (601/701), and LR-HPV accounted for 14.3% (100/701). Among the 214 cases of persistent infection with different HPV types, 89.7% (192/214) were high-risk transitions, and 10.3% (22/214) were low-risk transitions. Regardless of HPV types, HR-HPV was more likely to cause persistent infection than LR-HPV. In addition, over 60% of HR-HPV persistent infections resolved within 18 months, 30% developed into persistent infections, and only 15% of patients had persistent infections that last more than 24 months. Conclusion Persistent HPV infections are predominantly high-risk types. Most patients clear the infection within 18 months, approximately 30% develop persistent infections, and about 15% of patients have persistent infections that last more than 24 months. However, the HR-HPV persistent infection rates across different age groups slightly differ.

Mitochondria are the main site of energy metabolism in cardiomyocytes， and at the same time mediate apoptosis and immune response， so mitochondrial dysfunction is closely related to the development of heart failure. Combined with the pathogenesis of mitochondrial dysfunction and heart failure， it is proposed that the mitochondrial function is similar to "sweat pore - collaterals - zang and fu organs"， according to which the treatment of heart failure is based on the theory of "sweat pore - collaterals - zang and fu organs". It is believed that the core mechanism of heart failure is qi deficiency， and qi deficiency leads to the weakness of the sweat pore opening and closing， or even the sweat pore closure， then resulting in qi deficiency and blood stasis， collaterals stagnation fail to flourish， and qi， blood， and body fluids can not infiltrate and nourish zang-fu organs， so that the heart fail to be nourished， and the disease will develop. The treatment should be based on the method of boosting qi and opening sweat pore， using acridity to unblock the collaterals， and invigorating blood and draining water， with medicinal of boosting qi， invigorating blood， and draining water as treatment.

Objective:To analyze the disease burden in middle-aged and elderly population aged ≥55 in Shenzhen from 2016 to 2030 and provide evidence for the development of healthy aging strategies.Methods:The years of life lost (YLL), years lost due to disability (YLD), and the disability-adjusted life year (DALY) in this population from 2016 to 2022 were calculated. Joinpoint log-linear regression model was used to analyze the time trend. Bayesian age-period-cohort model and grey system model were used to predict YLL, YLD, and DALY in this population in 2030.Results:From 2016 to 2022, the crude DALY rate showed a transient fluctuation in age group 55-74 years, but a pronounced increase in age group ≥85 years. The proportions of YLL and YLD due to non-communicable diseases in all age groups was considerably higher than those due to communicable and nutritional diseases and injuries. In 2022, in all age groups, the YLL due to neoplasms (55-74 years old) and cardiovascular disease (≥75 years old) ranked first, and the YLD due to musculoskeletal disorder ranked first. By 2030, the causes of YLL and YLD ranking first in each age group would be remained, while the ranks of some causes would increase.Conclusions:The age specific characteristics of current and predicted disease burden differed in individuals aged ≥55 years. Therefore, it is necessary to allocate social and medical resources according to the disease burden pattern.

ObjectiveTo investigate the effect of phytoestrogen biochanin A （BCA） on liver fibrosis induced by CCl₄ in female mice with bilateral oophorectomy （ovariectomized） and its mechanism. MethodsA total of 50 ovariectomized Kunming mice were selected and given intraperitoneal injection of CCl₄ to establish a model of liver fibrosis， and then according to body weight， they were randomly divided into model group， positive control group， and low-， middle-， and high-dose BCA groups， with 10 mice in each group. In addition， 10 female mice in the same litter were given resection of a small amount of adipose tissue near both ovaries to establish the sham-operation group. The mice in the positive control group were given estradiol 2 mg/kg by gavage， and those in the low-， middle-， and high-dose BCA groups were given BCA by gavage at a dose of 25， 50， and 100 mg/kg， respectively， once a day for 7 consecutive weeks； the mice in the sham-operation group and the model group were given an equal volume of 0.5% sodium carboxymethyl cellulose solution by gavage. The mice were anesthetized and sacrificed after administration to collect samples. Liver index and uterus index were measured； HE staining and Masson staining were used to observe liver histopathological changes； the biochemical analysis was used to measure the activity of aspartate aminotransferase （AST） and alanine aminotransferase （ALT）； ELISA was used to measure the levels of interleukin-6 （IL-6） and tumor necrosis factor-α （TNF-α） in liver tissue， and Western blot was used to measure the relative protein expression levels of collagen Ⅰ， transforming growth factor-beta 1 （TGF-β₁）， alpha-smooth muscle actin （α-SMA）， estrogen receptor beta （ERβ）， and p-NF-κBp65/NF-κBp65 in liver tissue. The t-test was used for comparison of continuous data between two groups； a one-way analysis of various was used for comparison between multiple groups， and the least significant difference t-test was used for further comparison between two groups. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups and further comparison between two groups. ResultsCompared with the sham-operated group， the model group had a significant increase in liver index and a significant reduction in uterus index， as well as significant increases in the activities of serum AST and ALT， the levels of IL-6 and TNF-α in liver tissue， and the protein expression levels of collagen Ⅰ， TGF-β₁， α-SMA， and p-NF-κBp65/NF-κBp65 in liver tissue （all P<0.05）， with no significant change in the expression of ERβ in liver tissue （P>0.05）， and the model group showed significant fibrosis lesions in the liver， such as hepatocyte edema， steatosis， and necrosis with inflammatory cell infiltration and hyperplasia， deposition， and staggered distribution of collagen fibers. Compared with the model group， the low-， middle-， and high-dose BCA groups had significant reductions in liver index， the activities of serum AST and ALT， the levels of IL-6 and TNF-α， and the protein expression levels of collagen Ⅰ， TGF-β₁， α-SMA， and p-NF-κBp65/NF-κBp65 in liver tissue （all P<0.05）， with no significant change in uterine index （P>0.05）， as well as a significant increase in the protein expression level of ERβ in liver tissue （P<0.05） and varying degrees of improvement in liver fibrosis lesions. ConclusionBCA can effectively improve CCL₄-induced liver fibrosis in ovariectomized female mice， possibly by upregulating ERβ to inhibit the NF-κB signaling pathway and then alleviating inflammatory response.

Objective:Analyzing the gene expression microarray of patients experiencing acute asthma by bioinformatics methods,in order to explore the mechanism of acute asthma and to identify early indicator of acute asthma attacks.Methods:The GSE103166 microarray dataset was retrieved from the GEO database,and after cleaning and organizing the data,differential expres-sion analysis was conducted between children experiencing acute asthma attacks and non-asthmatic children.Enrichment analysis was performed using R language to annotate the functions of the differentially expressed genes(DEGs).Using gene interaction informa-tion,a network of interactions among these genes was constructed,and the network structure was deconstructed to identify key genes and regulatory sub-networks.Results:GSE103166 data set contained 87 nasal swab specimens from children(56 cases of acute asth-ma,31 cases of control).Compared with control group,the acute asthma group had 63 differentially expressed genes(39 upregulated and 24 downregulated).The results of enrichment analysis showed that the DEGs were primarily enriched in endocytic vesicle and en-docytic vesicle membrane.Among these,CD163 was the only gene significantly upregulated in both cellular components.The network dismantling analysis demonstrated four different sub-networks.CD163 was involved in sub-networkⅠ,which was composed of CD163,ARG2,CAT,GSTA2,SCNN1G and MT2A.Among them,ARG2 and CAT were at the regulatory center of the network.Conclusion:CD163 and regulatory networks based on CD163,ARG2,CAT,GSTA2,SCNN1G and MT2A are possible the crucial factors contributing to acute asthma.This study provides research ideas for the precise and early identification of biomarkers and thera-peutic targets for acute asthma attacks.

Objective:To establish the "1+3" management module of high-value consumables in Operation Room and verify its application, so as to provide new ideas for cost management of consumables in Operation Room.Methods:The Operating Room team of Shenzhen Hospital of Southern Medical University designed a "1+3" management module in 2022, where "1" referred to the management process of high-value consumables in Operation Room, and "3" referred to the precise management of consumables in Operation Room warehouse, the management of closed-loop use of Operation Room consumables and adverse event management of consumables. Surgeries using high-value consumables in the Thoracic Surgery Department, Gastrointestinal Surgery Department, and Urology Department of the hospital were selected as the research objects. The surgeries using conventional consumables from January to June 2022 were set as the control group, and the surgeries implementing the "1+3" management module from July to December 2022 were set as the observation group. The number of consumables received by the itinerant nurses before the operation and the number of high-value consumables returned after the operation were compared between the two groups. And the number of missed and error charges for high-value consumables in the two groups were counted and compared.Results:The number of consumables received before operation in the control group was higher than that in the observation group, and the difference was statistically significant ( P<0.05). The number of high-value consumables returned in the observation group was less than that in the control group, and the difference was statistically significant ( P<0.01). The proportion of missed charges for consumables in the observation group was lower than that in the control group, and the difference was statistically significant ( P<0.01), but there was no statistically significant difference in the proportion of incorrect charges between the two groups ( P>0.05) . Conclusions:The "1+3" management module for high-value consumables in Operation Room makes the process of receiving, returning, and charging high-value consumables clear, with traceable data, achieving refined management of high-value consumables in Operation Room, reducing the number of high-value consumables returned to the warehouse and reducing the proportion of missed consumables, which is conducive to effective cost control in Operation Room.
