Objective To make students at different levels not only learn theoretical knowledge of acupuncture-moxibustion manipulation skills but also achieve full operating training, strengthen the combination of theory and practice and improve the teaching quality of clinical disciplines by applyingmultimedia-subject participationteaching method to acupuncture-moxibustion manipulation techniques in the experimental teaching of acupuncture and moxibustion. Method The students were randomized, according to grade, into experiment (n=114) and control (n=115) groups. The teaching content was the same in the two groups. The experiment group received multimedia-subject participationteaching method. After the multimedia teaching, the students did an independent demonstration and made a self-evaluation, the teachers made a comment and the students did independent practice again in groups. The control group received conventional theory teaching and did practice under demonstration in the experimental lesson. The examination and questionnaire were used as assessment indicators to evaluate the effect ofmultimedia-subject participationteaching method applied to acupuncture-moxibustion technique teaching. Result Statistical analysis was made using the SPSS11.5 statistical software package. The independent samples t-test is used for a between-groups comparison. The statistical result showed that satisfaction was 100%in the experiment group and 75.7%in the control group;there was a statistically significant difference between the two groups (P<0.05). Conclusion Multimedia-subject participationteaching method is an innovation in acupuncture-moxibustion technique teaching and helps the students to better master acupuncture-moxibustion manipulation skills. Mastery of theoretical knowledge before real practice is the key to proficient manipulation. The combination of the two in classroom teaching yields twice the result with half the effort. Carrying out multimedia-subject participation teaching method will help to further deepen the teaching reform and to improve the level and quality of“Acupuncture and Moxibustion”teaching.

Objective To investigate the protective effect of wogonin on acute kidney injury(AKI)induced by li-popolysaccharide(LPS).Methods The model of septic-induced AKI was established on male C57BL/6J mice by a single intraperitoneal injection of LPS and normal C57BL/6J mice were used as normal control group.Twenty-four male C57BL/6 mice were randomly divided into 4 groups(6 mice in each group):normal control group(NC),normal control+wogonin(NC+WOG 12.5 mg/kg),LPS model group(LPS 10 mg/kg),LPS model+wogonin(LPS 10 mg/kg+WOG 12.5 mg/kg).After LPS intervention for 24 h,serum samples were collected to detect blood creatinine(CRE)and urea nitrogen(BUN)levels.HE staining and PAS staining were performed to observe the degree of renal pathological injury.Immunohistochemistry was performed to detect the degree of expression of inflammatory markers interleukin(IL)-1 β,IL-6 and tumor necrosis factor(TNF)-α in renal tissues.PCR was performed to detect the expression of KIM-1 and NGAL in renal tissues.Western blot was performed to detect the changes in protein expression of NF-κB signaling pathway subunits P65 and PP65 in renal tissues.Results Com-pared with NC group,CRE and BUN levels in LPS group increased(FCRE=60.90,P<0.001,FBUN=82.13,P<0.001);compared with LPS group,these indexes decreased in LPS+WOG group(P<0.001).PCR test re-sults showed that compared with the NC group,the expression of KIM-1 and NGAL mRNA was significantly in-creased in LPS group(FKIM-1=146.3,P<0.001,FNGAL=161.2,P<0.001).In contrast,KIM-1 and NGAL mR-NA expression was decreased in the LPS+WOG group(P<0.01).Renal histopathological examination showed that compared with the NC group,renal tissues of mice had renal tubular dilatation and inflammatory cell infiltration in LPS group;compared with LPS group,the number of tubular dilatation reduced and inflammatory cell infiltration was reduced in LPS+WOG group(FHE=721.4,P<0.001;FPAS=518.9,P<0.001).Immunohistochemical staining showed that the expression of IL-1 β,IL-6 and TNF-α was significantly increased in the LPS group;com-pared with the LPS groups(FIL-1β=114.6,FIL-6=108.9,FTNF α=251.6,all P<0.001),these indexes de-creased in LPS+WOG group(all P<0.01).Further studies using Western blot showed that the NF-κB signaling pathway of LPS-treated mice had been activated and produced a hyperphosphorylated state in comparison to the NC group(FPP65=13.02,P<0.01),yet this pathway in the LPS+WOG group showed the opposite effect,namely attenuated activity and reduced phosphorylation when the control was LPS(P<0.01).Conclusion WOG effec-tively blocked the NF-κB signaling pathway in the LPS-induced acute kidney injury model mice,thereby attenua-ting the inflammatory response and tissue damage in the kidneys of LPS-induced acute kidney injury mice.

Objective:To screen and identify H-2 d-restricted T cell epitopes in fusion (F) and attachment (G) glycoproteins of Nipah virus (NiV) in mice. Methods:The complete peptides (single peptide contains 15 amino acids, and 10 amino acids were repeated in the front and back peptides) derived from F and G antigens were mixed into peptide libraries. BALB/c mice were immunized with DNA vaccines expressing NiV F and G proteins alone and in combination. The full sequence peptide libraries of F and G antigens were mixed into peptide pools by matrix design, and spleen cells of immunized mice were collected and analyzed by IFN-γ ELISPOT assay to detect the dominant H-2 d-restricted epitope peptides. Results:Twelve dominant H-2 d-restricted peptides were screened from the F protein-specific peptide library and the 56th peptide produced the strongest reaction. Four dominant peptides were screened from the G protein-specific peptide library and the 72nd peptide produced the strongest reaction. Conclusions:In this study, 12 F antigen-specific and 4 G antigen-specific H-2 d restricted dominant T cell epitopes of NiV were screened and identified by IFN-γ ELISPOT, which could provide reference for immunological analysis of NiV and vaccine research.

Liver cholesterol metabolism disorder plays an important role in the development of non-alcoholic fatty liver disease (NAFLD).In order to reveal the molecular mechanism of cholesterol homeostasis imbalance induced by saturated fatty acids, HepG2 cells were stimulated with palmitic acid (PA).Lipids accumulation was analyzed by Oil Red O staining, intracellular triglyceride and cholesterol quantification.The level of genes and proteins related to cholesterol homeostasis was measured by RT-qPCR and western blotting.Additionally, intracellular bile acids and mitochondrial oxysterols were detected by LC-MS/MS.The results demonstrated that intracellular lipids such as TG and TC were significantly increased in the model with PA stimulation.Although no significant difference was detected in genes related to cholesterol synthesis and uptake, the protein expression of ABCG5 and LXRα were significantly down-regulated, indicating a decrease in cholesterol efflux.Meanwhile, the gene expression of STARD1 and CYP7B1, which are responsible for bile acid alternative synthesis, were markedly enhanced, along with a significant increase of cholesterol and 27-OHC in mitochondria and CDCA in cells.These results suggested that PA overload may disrupt cholesterol homeostasis by inhibiting cholesterol efflux and promoting bile acids synthesis.

Objective:To evaluate the efficacy and safety of Qingxuan Zhike granules in improving cough symptoms and shortening the course of influenza (wind-heat invading lung) in children.Methods:In this multicenter, randomized, controlled clinical trial, a total of 240 outpatient influenza patients from 7 hospitals, including the First Affiliated Hospital of Yunnan University of Traditional Chinese Medicine, from April 2023 to December 2023 were collected.The subjects were randomly divided into the control group and the experimental group via SAS software using the block randomization method.The differences between two groups were compared with t test, corrected t test and χ2 test.Subjects in the control group were given Oseltamivir phosphate granules, orally, twice a day (weight ≤15 kg, 30 mg/time; weight >15-23 kg, 45 mg/time; weight >23-40 kg, 60 mg/time; weight >40 kg, 75 mg/time; age≥13 years, 75 mg/time).In addition to Oseltamivir phosphate granules, subjects in the experimental group were also given Qingxuan Zhike granules, orally, 3 times a day (1-3 years old, 1/2 bag each time; >3-6 years old, 3/4 bag each time; >6-14 years old, 1 bag each time).After 5 days of treatment, the medication was suspended for 2 days.The effect of cough, antipyretic effect, clinical recovery rate, clinical recovery time, Canadian Acute Respiratory Illness and Flu Scale (CARIFS) score, traditional Chinese medicine (TCM) syndrome effect, complication rate, and adverse reactions were evaluated between the two groups. Results:Finally, 232 cases were included in the study, including 115 cases in the experimental group and 117 cases in the control group.Before and after treatment, there were no significant difference in CARIFS cough score between the experimental group and the control group (all P>0.05).After treatment, the change in CARIFS cough score in the experimental group [(-1.00±0.91) scores]was significantly higher than that in the control group [(-0.75±0.98) scores] ( t=-1.995, P=0.047).After treatment, the change in TCM syndrome cough score in the experimental group [(-1.69±1.51) scores] was significantly higher than that in the control group [(-0.97±1.63) scores] ( t′=-0.035, P=0.001).The time of complete regression of fever in the experimental group [(44.82±22.72) h] was shorter than that in the control group [(51.35±27.07) h], and the difference between the two groups was statistically significant ( t=-1.966, P=0.050).The fever score showed that the area under the curve between the CARIFS symptom fever score and time in the experimental group was 4.40±2.42, while that in the control group was 5.12±2.44, and the difference between the two groups was statistically significant ( t=-2.252, P=0.025).The clinical recovery rate was 93.91%(108/115) in the experimental group and 92.31%(108/117) in the control group, and there was no significant difference between the two groups ( χ2=0.233, P>0.05).The clinical recovery time in the experimental group [(2.93±1.21) d] was shorter than that in the control group [(3.29±1.15) d], and the difference between the two groups was statistically significant ( t=-2.279, P=0.024).After treatment, there was a significant difference in TCM syndrome score variation between the experimental group [(-12.00±4.13) scores] and the control group [(-10.85±4.31) scores] ( t′=-2.067, P=0.040).No complication occurred in both groups, and there was no significant difference in the incidence of adverse events between the two groups ( χ2=1.299, P>0.05). Conclusions:Qingxuan Zhike granules combined with Oseltamivir phosphate can effectively improve the cough symptoms associated with influenza in children, shorten the time and course of fever, and improve the TCM syndrome score; thus, they are safe in clinical application.
