ObjectiveTo investigate the efficacy and safety of Babaodan Capsule （BBD） in the treatment of patients with chronic hepatitis B virus （HBV） infection with damp-heat in the liver and gallbladder comorbid with gallbladder polyps. MethodsA randomized， double-blinded， placebo-controlled single-center trial was conducted among 120 patients with chronic HBV infection who were admitted to Beijing YouAn Hospital， Capital Medical University， from August 2020 to April 2023， and they were divided into treatment group （BBD） and control group （placebo）， with 60 patients in each group. The course of treatment was 24 weeks， and follow-up assessments were conducted every 4 weeks. The primary outcome measures were the number and maximum diameter of gallbladder polyps （assessed by ultrasound）， and the secondary outcome measures included traditional Chinese medicine （TCM） syndrome score， blood lipid levels， and liver function parameters. The independent-samples t test or the Wilcoxon rank-sum test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups； the Wilcoxon rank-sum test was used for comparison of ranked data between two groups； the generalized estimating equation was used to analyze repeated measures data. ResultsAfter 8 weeks of treatment， the treatment group had a significantly smaller diameter of polyps and a significantly lower number of polyps than the control group （Z=-1.76 and -1.80， both P<0.05）， and after 24 weeks of treatment， the treatment group had a significantly higher polyp reduction rate than the control group （30.51% vs 10.91%， P<0.05）. The subgroup analysis showed that patients receiving combined antiviral therapy， male patients， patients with a diameter of polyps of <5 mm， and patients with multiple polyps tended to achieve significantly greater benefits. At week 8 of treatment， the treatment group had a significantly better TCM syndrome score than the control group （Z=-2.35， P<0.05）； after treatment， compared with the control group， the treatment group had a significantly greater increase in high-density lipoprotein （Z=-1.85， P<0.05） and significantly lower levels of alanine aminotransferase （Z=-2.06， P <0.05）， aspartate aminotransferase （Z=-2.13， P<0.05）， total bilirubin （Z=-2.12， P<0.05）， and direct bilirubin （Z=-3.09， P<0.05）. No serious adverse events were reported in either group. ConclusionBBD can effectively reduce the size of gallbladder polyps， improve TCM syndrome score， and reduce the level of bilirubin in patients with chronic HBV infection with damp-heat in the liver and gallbladder， with a favorable safety profile， and it may be more suitable for patients receiving combined antiviral therapy and specific subgroups （male patients， patients with a diameter of polyps of <5 mm， and patients with multiple polyps.

OBJECTIVE: To observe the effects of Xingnao Kaiqiao acupuncture technique (for regaining consciousness and opening orifice) on methylation of N6-methyladenosine (m6A), and key methyltransferases and demethylases, so as to clarify the mechanism of acupuncture on cerebral ischemia-reperfusion injury (CIRI). METHODS: Of 68 male Sprague-Dawley rats of SPF grade, 15 rats were randomly selected as a sham-operation group, and the remaining rats were subjected to the model of middle cerebral artery occlusion using the suture ligation. CIRI was induced by ischemia for 2 h followed by reperfusion. Rats that failed to modeling or died were excluded. The rest 45 rats were randomly divided into three groups, i.e. model group, acupuncture group, and non-point acupuncture group, with 15 rats in each group. The rats in the acupuncture group were treated with acupuncture at bilateral "Neiguan" (PC6) and "Shuigou" (GV26). In the non-point acupuncture group, acupuncture was delivered at three non-points, located 3 mm below the bilateral midaxillary line and 3 mm lateral to the tip of the coccyx. One intervention was operated in these two acupuncture groups and the needles were retained for 30 min. Before modeling start and 2 h after ischemia, a laser speckle flowmeter was used to monitor the cerebral blood perfusion. In 2 h of ischemia and 24 h of reperfusion, the neurological behavioral score was evaluated. The volume of rat cerebral infarction was determined by triphenyltetrazolium chloride (TTC) staining, and the level of m6A methylation in ischemic cortical area was detected by Dot blot, and the protein and mRNA expression of the demethylase i.e. fat mass and obesity-associated protein (FTO), AlkB homolog 5 (ALKBH5) and key methyltransferases, i.e. methyltransferase-like 3 (METTL3), methyltransferase-like 14 (METTL14), and Wilms' tumor 1-associated protein (WTAP) in ischemic cortical area were detected by Western blot and real-time PCR. RESULTS: Cerebral blood perfusion decreased by>70% after 2 h ischemia. Compared with the sham-operation group, the neurobehavioral score and the percentage of cerebral infarction volume increased in the model group (P<0.01); the level of m6A methylation in the ischemic cortical area increased (P<0.01), the protein and mRNA expression of FTO decreased (P<0.01), and that of ALKBH5, METTL3, and METTL14 increased (P<0.01, P<0.05) in the model group. When compared with the model group and the non-point acupuncture group, the acupuncture group showed a decrease in the neurobehavioral score and the percentage of cerebral infarction volume (P<0.01), the level of m6A methylation in the ischemic cortical area was reduced (P<0.01, P<0.05), and the protein and mRNA expression of FTO was elevated (P<0.01). CONCLUSION Xingnao Kaiqiao acupuncture technique presents its protective effect on the brain in the rats with CIRI, which is related to up-regulating the expression of FTO and modulating m6A methylation.

Objective:To explore the interrelationship among three simplified hand and wrist bone age assessment methods and to establish corresponding bone ages for each substage in male children.Methods:This retrospective case series study included 169 left hand and wrist X-rays from 152 male children who underwent bone age assessments at the Pediatric Orthopedics and Pediatrics Departments,Beijing Jishuitan Hospital,Capital Medical University from January 2019 to December 2023. The age at the time of X-ray was (13.7±2.0) years (range:9.1 to 17.9 years). Reasons for bone age assessment included evaluating the progress of adolescent idiopathic scoliosis in 36 cases, predicting limb length discrepancies in 28 cases, and predicting the height of healthy adolescents in 88 cases. Bone age was first graded using the Chinese hand-wrist bone age assessment method. Three simplified hand and wrist bone age assessment methods were then applied:Sanders simplified skeletal maturity staging system(Sanders stage), the distal radius and ulna classification (DRU), and e thumb ossification composite index (TOCI). Somers′delta correlation test was used to analyze the relationship among the results of the three simplified methods. The bone age and standard deviation for each sub-stage were calculated, and gender differences in bone age for the same sub-stage were compared with previous study.Results:The DRU, TOCI and Sanders stages showed a strong correlation when assessing bone age in male children, with Somers′delta correlation coefficients ranging from 0.881 to 0.876 (all P<0.01). The sub-stages with the smallest standard deviations (shorter duration) in each of the three classifications can serve as a quick reference for determining precise bone age, included proximal thumb epiphysis covered, without sesamoid (12.0 years);proximal thumb epiphysis covered with sesamoid or distal radial covered (13.0 years), early capping of the thumb epiphysis, radial epiphysis medial side capping(13.5 years), all phalangeal epiphyses capping (14.0 years), distal phalangeal physes beginning to close (14.5 years), all distal phalangeal physes closed (15.0 years), middle or proximal phalangeal physes beginning to close (15.5 years), all digital epiphyses closed (16.5 years), and nearly complete distal radius fusion with a notch (17.5 years). On average, the bone ages of males were 2 years behind those of females in the same substage. Conclusions:The DRU, TOCI, and Sanders stages can be applied to male children, and it is showed good correlation between them. The subtypes with shorter duration can be used as a quick assessment method to determine the bone age.

Objective:To analyze the growth characteristics of different genotypes of Japanese encephalitis virus (JEV) in different cell lines, and to provide scientific basis for the selection of cell lines in the study of JEV.Methods:BHK-21, Vero, C6/36, PK-15, DF-1, N2a, SH-sy5y and MDCK cell lines were selected. The proliferation ability of genotype 1 (NX1889 strain), genotype 3 (P3 strain) and genotype 5 (XZ0934 strain) JEV in these cell lines was evaluated by plaque assay and RT-qPCR.Results:Significant cytopathogenic effects (CPE) were observed in BHK-21, Vero, C6/36, DF-1, N2a and PK-15 cell lines across all three JEV genotypes. However, no significant differences in CPE characteristics were observed within the same cell line. SH-sy5y and MDCK cell lines did not show significant CPE, but virus proliferation was detected in SH-sy5y cell line, while MDCK cell line were found to be insensitive to JEV. No significant difference was observed in the proliferation curves of G1, G3 and G5 JEV in BHK-21, Vero and SH-sy5y cell lines. In C6/36 and PK-15 cell lines, the titer of G1 JEV was higher than that of G3 and G5. In DF-1 cell line, G5 demonstrated a higher titer than the other two genotypes, whereas in N2a cell line, G5 showed a lower titer than the other two.Conclusions:There are differences in the proliferation of three different genotypes of JEV in different cell lines, which can provide reference for the study of JEV in different directions.

Objective: To uncover the underlying mechanisms of action of the Yinlai decoction on high-calorie diet-induced pneumonia through proteomics analysis. Methods: Based on the Gene Expression Omnibus (GEO) database, lung tissue samples from normal and high-fat diet (HFD) fed mice in the GSE16377 dataset were selected as test cohorts to identify differentially expressed genes and conduct bioinformatics analyses. In the animal experiments, mice were randomly divided into the control (N), high-calorie diet pneumonia (M), and Yinlai decoction treatment (Y) groups. Mice in the M group received high-calorie feed and a 0.5 mg/mL lipopolysaccharide solution spray for 30 min for 3 d. The mice in the Y group were intragastrically administered 2 mL/10 g Yinlai decoction twice daily for 3 d. Pathological evaluation of the lung tissue was performed. Differentially expressed proteins (DEPs) in the lung tissue were identified using quantitative proteomics and bioinformatics analyses. The drug-target relationships between Yinlai decoction and core DEPs in the lung tissue were verified using AutoDock Vina and Molecular Graphics Laboratory (MGL) Tools. DEPs were verified by western blot. Results: GEO data mining showed that an HFD altered oxidative phosphorylation in mouse lung tissue. The Yinlai decoction alleviated pathological damage to lung tissue and pneumonia in mice that were fed a high-calorie diet. A total of 47 DEPs were identified between the Y and M groups. Enrichment analysis revealed their association with energy metabolism pathways such as the tricarboxylic acid cycle (TCA) and oxidative phosphorylation. The protein-protein interaction network revealed that Atp5a1, Pdha1, and Sdha were the target proteins mediating the therapeutic effects of Yinlai decoction. Molecular docking results suggested that the mechanism of the therapeutic effect of Yinlai decoction involves the binding of brassinolide, praeruptorin B, chrysoeriol, and other components in Yinlai decoction to Atp5a1. Conclusion The Yinlai decoction alleviated lung tissue damage and pneumonia in mice that were fed a high-calorie diet by regulating the TCA and oxidative phosphorylation. Our study highlights the importance of a healthy diet for patients with pneumonia and provides a scientific basis for the prevention and treatment of pneumonia through dietary adjustments.
