ObjectiveTo observe the effect of Yangxin Tongmai Formula （养心通脉方） by midnight-noon ebb-flow administration method for rat models of premature coronary heart disease （PCHD） with blood stasis syndrome， and to explore the possible mechanism of action from the perspective of DNA methylation differential gene expression. MethodsThere were 3 SD rats in each of the blank group， model group and Yangxin Tongmai Formula group， and the rats in the model group and Yangxin Tongmai Formula group were fed with high-fat chow plus vitamin D3 by gavage plus isoproterenol hydrochloride by subcutaneous injection to construct rat models of PCHD with blood stasis syndrome. After successful modelling， rats in Yangxin Tongmai Formula group were gavaged with 18 g/（kg‧d） of Yangxin Tongmai Formula， and rats in blank group and the model group were gavaged with 4 ml/（kg‧d） of 0.9% NaCl solution， and serum samples of rats in each group were collected for DNA methylation sequencing after 3 weeks to screen for the relevant DNA methylation differentiation genes. In addition， rats with successful modelling of PCHD with blood stasis were randomly divided into model group， Yangxin Tongmai Formula with midnight-noon ebb-flow administration method group ［18 g/（kg‧d） of Yangxin Tongmai Formula was gavaged twice in the heart channel period （12：00） and pericardium channel period （20：00）］， the Yangxin Tongmai Formula control group ［18 g/（kg‧d） of Yangxin Tongmai Formula was gavaged twice at 8：00 and 18：00］ and the Atorvastatin Calcium group ［atorvastatin calcium tablets solution 1.8 mg/（kg‧d） at the same intervention time as that in Yangxin Tongmai Formula control group］， and set up a blank group of 8 rats in each group. The model group and blank group were gavaged with 0.9% NaCl solution 4 ml/（kg‧d） for the same time as the Yangxin Tongmai Formula control group. After 3 weeks of gavage， the blood lipids ［including total cholesterol （TC）， low-density lipoprotein （LDL）， high-density lipoprotein （HDL）］ levels of rats in each group were detected； the HE staining of myocardial tissues and thoracic aorta was used to observe the pathomorphological changes； the levels of serum inflammation indexes ［tumour necrosis factor alpha （TNF-alpha）， lipopolysaccharide （LPS）， and interleukin 10 （IL-10）］ were detected； immunoprecipitation-realtime fluorescence quantitative PCR was used to detect the relative expression of cardiac tissue screening differential genes. ResultsThe genes screened for differentially methylated regions were calmodulin 2 （Calm2）， calcium voltage-gated channel subunit α1s （Cacna1s）， and phospholipase Cβ1 （Plcb1）. Compared with the blank group， rats in the model group showed elevated levels of TC， LDL， TNF-α and LPS， and decreased levels of HDL and IL-10 （P＜0.05 or P＜0.01）； HE staining showed obvious swelling of myocardial fibres， accompanied by a large number of inflammatory cell infiltration， and thickening of the inner wall of the aortic vessels with internal wall damage， which was visible as a large number of lipid cholesterol crystals and obvious inflammatory cell infiltration. Compared with the model group， the TC， LDL， TNF-α and LPS contents of rats in the Yangxin Tongmai Formula with midnight-noon ebb-flow administration method group， the Yangxin Tongmai Formula control group， and the atorvastatin calcium group all reduced， and the contents of HDL and IL-10 all elevated （P＜0.05）， with the improvement of myocardial tissue damage and the reduction of inflammatory infiltration， and the improvement of the damage of the inner lining of the thoracic aorta and the reduction of lipid infiltration. Compared with Yangxin Tongmai Formula control group， LDL， TNF-α and LPS contents reduced， and IL-10 contents increased in the midnight-noon ebb-flow administration method group （P＜0.05）. Compared with the model group， the relative expression of Calm2 and Plcb1 genes decreased and the relative expression of Cacna1s gene increased in Yangxin Tongmai Formula control group and the midnight-noon ebb-flow administration method group （P＜0.05）； compared with the Yangxin Tongmai Formula control group， the relative expression of Calm2 gene decreased and the relative expression of Cacna1s gene increased in the midnight-noon ebb-flow administration method group （P＜0.05）. ConclusionThe intervention of Yangxin Tongmai Formula in the heart channel period （12：00） and pericardium channel period （20：00） was more effective in improving the blood lipid level， inhibiting inflammation， and improving myocardial tissue damage in rats of PCHD with blood stasis syndrome， and Calm2 and Cacna1s genes may be the key targets of Yangxin Tongmai Formula in intervening the blood stasis syndrome of PCHD.

With the introduction and implementation of relevant policies such as the outline of "Healthy China 2030" plan and Healthy China Action (2019-2030), the health service function of traditional Chinese medicine (TCM) has been valued and developed. TCM health literacy has become one of the important ways to promote the health of the whole population. TCM health preservation literacy refers to the ability of individuals to obtain TCM health preservation concepts, knowledge and technical services, and to make correct health care decisions to promote their own health by using knowledge and information as well as medical and technical services. According to survey data from the National Administration of Traditional Chinese Medicine, the compliance rate of TCM health literacy among Chinese citizens has increased from 8.55% in 2014 to 24.62% in 2023, and is still on the rise. However, there are differences in the level of TCM health literacy among different regions, genders, and occupational groups. This article retrieves relevant literature published on CNKI and Wanfang Data from the establishment of the databases until December 2024. The content is sorted out using thematic analysis, and a review is conducted on the concept, evaluation tools, current status, and influencing factors of TCM health literacy. This article provides a reference for enhancing public health awareness and improving the level of TCM health literacy.

Objective To investigate whether aberrant DNA methylation of ubiquinol-cytochrome C reductase core protein 1(UQCRC1)is related to cognitive impairment caused by neonatal sevoflurane exposure.Methods A total of 94 SPF C57 mice of either sex,aged 6 d,and weighing 4～6 g,were randomly divided into 7 groups:control group(Con,n=6),sevoflurane-6 and-24 h exposure groups(Sev-6 and-24 h,n=6),control+DMSO group(Con+DMSO,n=19),control+5-aza-2'-deoxycytidine(5-AZA,methylation inhibitor)group(Con+5-AZA,n=19),sevoflurane+DMSO group(Sev+DMSO group,n=19),and sevoflurane+5-AZA group(Sev+5-AZA group,n=19).From 6 to 8 d after birth,the mice of the Sev-6 and-24 h exposure groups were exposed to 3％sevoflurane daily(with 97％oxygen,2 L/min,2 h per day),while those from the Con groups were given exposure of 100％oxygen(2 L/min,2 h per day).For the mice of the 5-AZA and DMSO groups,1 mg/kg of 5-AZA or an equal volume of DMSO was injected intraperitoneally 30 min before daily exposure.In 6 and 24 h after the last exposure to sevoflurane,6 mice from the Con,Sev-6 h,and Sev-24 h groups were euthanized for biochemical analysis,and in 24 h post-exposure,6 mice from the Con+DMSO,Con+5-AZA,Sev+DMSO,and Sev+5-AZA groups were randomly selected for biochemical analysis,while another 3 mice from above each group were also randomly selected for morphological analysis.The remaining 10 mice in these groups underwent behavioral testing(open field test,novel object test,and Y-maze test)at 30～33 d after birth to assess cognitive function,and were euthanized in 24 h after the final behavioral test.RT-qPCR and Western blotting were used to detect the hippocampal expression of UQCRC1,DNA methyltransferases(Dnmts),and methyl CpG binding protein 2(Mecp2)at mRNA and protein levels,respectively.Immunofluorescence assay was employed to observe the distribution and expression of UQCRC1 in the hippocampus.Bisulfite sequencing PCR(BSP)was applied to measure the methylation in the UQCRC1 promoter region.Results Compared with the Con group,the mRNA and protein levels of UQCRC1 were down-regulated(P<0.05),and the mRNA level of Dnmts was up-regulated(P<0.05)in both the Sev-6 h and Sev-24 h exposure groups,while the methylation level in the UQCRC1 promoter region was enhanced in the Sev-24 h exposure group(P<0.05).Additionally,the Sev+5-AZA group had obviously increased mRNA and protein levels of UQCRC1(P<0.05),and notable improvement in cognitive impairment(P<0.05)when compared with the Sev+DMSO group.Conclusion Hypermethylation of UQCRC1 promoter region and thus down-regulating its mRNA and protein expression might be the main mechanism by which repeated neonatal sevoflurane exposure induces cognitive impairment later in life.

Objective To clarify the active ingredients and the potential molecular mechanism of Guben Qushi Huayu Prescription in treating psoriasis recurrence.Methods An ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF/MS)was applied to analyze the whole formula and the constituents absorbed into blood of Guben Qushi Huayu Prescription,and molecular docking technology was used to study the binding affinity of the constituents absorbed into blood with psoriasis-related immunomodulatory proteins such as CD69 and CD103 proteins.Results Mass spectrometry analysis identified 21 active ingredients such as paeoniflorin in Guben Qushi Huayu Prescription,including several known anti-inflammatory and immunomodulatory compounds.Analysis of the constituents absorbed into blood identified 11 ingredients,including paeoniflorin,that may affect the course of psoriasis through blood circulation.Molecular docking studies revealed that the constituents absorbed into blood,including astilbin,isoastilbin,chlorogenic acid,neochlorogenic acid,cryptochlorogenic acid,helicine,paeoniflorin,ononin,all had high binding affinities with CD69 and CD103 proteins.Conclusion This research reveals the main active ingredients of Guben Qushi Huayu Prescription and their potential mechanism for regulating the recurrence of psoriasis by mass spectrometry and molecular docking technology,contributing to providing scientific basis for further pharmacological research and clinical application.

Objective:To explore the effects of intraspinal blocking analgesia on the delivery quality and puerperal pelvic floor function of primiparas.Methods:A total of 99 primiparas who delivered in the Second People′s Hospital of Wuhu City from January 2021 to April 2022 were enrolled in this study, 54 patients received intraspinal blocking analgesia (study group) and 45 patients received conventional treatment, without intraspinal blocking analgesia (control group). The delivery quality between the two groups was compared, and the pelvic floor function was evaluated and compared by pelvic floor rehabilitation therapy instrument and pelvic floor ultrasound at 6-8 weeks after delivery.Results:Vaginal delivery were successful in both groups. The total labor duration in the study group was longer than that in the control group: (8.03 ± 2.94) h vs. (6.89 ± 3.49) h, there was statistical difference ( P<0.05). The maximum value of pelvic floor rapid contraction stage, rising time and average value of continuous contraction stage in the study group were higher than those in the control group: (32.85 ± 10.13) μV vs. (14.73 ± 3.25) μV, (0.28 ± 0.06) s vs. (0.22 ± 0.05) s, (30.26 ± 5.24) μV vs. (16.74 ± 4.00) μV, there were statistical differences ( P<0.05). There were no statistical differences in other indicators such as the pre-resting stage, rapid contraction phase recovery time and post-resting stage between the two groups ( P>0.05). The rate of pelvic floor class Ⅰ and class Ⅱ muscle abnormalities at 6-8 weeks after delivery in the study group were lower than those in the control group, but there were no statistical differences ( P>0.05). The maximum Valsalva state hiatus area of levator ani muscle, maximum Valsalva state bladder posterior urethral angle, hiatus area of levator ani muscle at rest state and bladder neck degree in the study group were smaller than those in the control group: (19.09 ± 4.82) cm 2 vs. (23.00 ± 5.34) cm 2, (138.59 ± 23.14)° vs. (148.47 ± 20.38)°, (9.96 ± 2.63) cm 2 vs. (11.60 ± 2.75) cm 2, (20.13 ± 4.37) mm vs. (28.05 ± 6.52) mm, there were statistical differences ( P<0.05). Conclusions:Although intraspinal block analgesia can prolong the total labor time of primipara, but it can reduce the damage of pelvic floor function, possibly by increasing systolic period to protect pelvic floor muscles.

Objective:To explore the clinical effect of using great toe fibular flaps of both feet on reconstruction of pulp defects of two neighbouring digits.Methods:A total of 14 digit pulp defects in 7 cases were repaired in Zhoukou Huaihai Hospital using great toe fibular flaps of both feet from August 2020 to January 2023. Of the 7 cases, there were 4 males and 3 females, with an average of 28 years old, ranging from 19 to 45 years old. Meanwhile, there were 4 cases in left hand and 3 cases in right hand.

The donor site of the great toe fibular flap left linear scars only, without abnormality in range of motion and gait in walking. In addition, there were 5 in excellent and 2 in good according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association.Conclusion:Application of great toe fibular flaps of both feet is an ideal option for the simultaneous repair of pulp defects of two neighbouring digits, which can achieve good reconstructive results.

OBJECTIVE To establish the characteristic chromatogram of the volatile oil in the standard decoction of Qingshang juantong decoction， and preliminarily infer the main active components of volatile oil that affect the clinical therapeutic effect. METHODS The volatile oil in the standard decoction of Qingshang juantong decoction was extracted by steam distillation. The ultra-high performance liquid chromatography （UPLC） characteristic chromatograms of 15 batches of samples were established by the Similarity Evaluation System of TCM Chromatographic Fingerprint （2012 edition）， and the similarity evaluation was carried out. The volatile oil of standard decoction was identified by UPLC coupled with quadrupole time-of-flight mass spectrometry （UPLC-Q-TOF/MS）. Then the volatile oil components were analyzed by GC-MS. RESULTS The similarities of UPLC characteristic chromatograms for volatile oil of 15 batches of Qingshang juantong decoction were between 0.949 and 0.997. A total of 12 common peaks were obtained. According to the UPLC-Q-TOF/MS， the main components were methyl eugenol， E-ligustilide， E-butylidenephthalide and so on. A total of 23 components were identified by GC-MS， which were mainly 3，4，5-trimethoxy- methylbenzene， patchouli alcohol， Z-ligustilide and so on. CONCLUSIONS The characteristic chromatograms of the volatile oil in the standard decoction of Qingshang juantong decoction is established， and it is inferred that methyl eugenol， ligustilide， E- butylidenephthalide， patchouli alcohol， 3，4，5-trimethoxy-methylbenzene might be the main active components affecting the clinical therapeutic effect of the volatile oil of Qingshang juantong decoction.

Objective The aim of this study was to screen and verify the proteins interacting with Vimentin,investigate the regulatory relationship between FABP5 and candidate proteins,and further explore the mechanism of FABP5 in hepatocellular carcinoma.Methods Immunoprecipitation combined with tandem mass spectrometry(IP-MS)was used to screen the proteins that bind to FABP5.The binding relationship between FABP5 and candi-date interacting proteins was verified from the exogenous and endogenous levels by Co-immune precipitation assay(Co-IP).RT-qPCR,Western blot and immunofluorescence were used to observe the effect of knockdown FABP5 on the transcription and translation of Vimentin in HCC cells.The effect of overexpressing FABP5 on the cytoskeleton of HCC cell was observed by phalloidin staining.Results 336 potential target proteins that bind to FABP5 were identi-fied through IP-MS.Based on literature,five candidate proteins related to tumors were selected,namely PRDX1,PRSS3,PKM,HSP90AA1,and Vimentin.The binding relationship between FABP5 and Vimentin protein was con-firmed through both exogenous and endogenous Co-IP.Knockdown FABP5 has no significant effect on the expression of Vimentin mRNA,but it can inhibit the expression of Vimentin protein,and overexpression of FABP5 can affect the cytoskeleton of HCC cell.Conclusions FABP5 promotes the migration and invasion of HCC cells by the regula-tion of Vimentin and the influence of cytoskeletal remodeling,and thus it is expected to be a potential target for anti-HCC and provide new ideas for the treatment of HCC.

Objective:To explore the clinical efficacy of free superficial circumflex iliac artery perforator flap (SCIAPF) in reconstruction of soft tissue defects of hand and foot in children.Methods:From August 2021 to August 2023, free SCIAPFs were used to reconstruct soft tissue defects of hands and feet in 8 children at the Department of Hand and Foot Surgery, Zhoukou Huaihai Hospital. There were 6 boys and 2 girls aged between 2 and 7 years old. The sites of soft tissue defect were: 1 of metacarpophalangeal joint in the functional area of left thumb, 2 of dorsal right hand, 1 of dorsal left foot, 2 of medial malleolus of right foot, and 2 of right forefoot, and all were accompanied with tendon and bone exposure. The size of soft tissue defects ranged from 2.5 cm×3.0 cm to 6.0 cm×3.5 cm. After emergency debridement, the children received flap transfers, the flaps sized from 3.0 cm×3.5 cm to 7.0 cm×4.0 cm. Donor sites were closed by running intradermal suture. All children were included in the scheduled postoperative follow-up by visit of outpatient clinic, WeChat interviews and home visits to observe the appearance, colour, texture and sensation of the flaps, the functional recovery of the affected hands and feet, as well as the healing of donor sites.Results:After surgery, all 8 flaps survived beside 1 had a partial necrosis at the edge and healed with a scab after dressing change. Flap donor sites healed in one stage. Scheduled postoperative follow-up lasted from 7 to 22 months, with an average of 10 months. The flaps presented a slightly bloated appearance, soft texture with a restored protective sensation and satisfactory functional recovery of hands and feet. Linear scars were left at the donor sites. According to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 1 child was of excellent and 2 children of good in hand function of the 3 children with hand injury. The Maryland Foot Score revealed 3 children were of excellent and 2 of good in foot function of the 5 children with foot injury.Conclusion:Free SCIAPF is an ideal option for reconstruction of soft tissue defects of hand and foot in children, with concealed donor site, convenient flap harvesting, fewer complications and satisfactory reconstructive effect.

Objective To investigate the application of artificial intelligence-based follow-up plan for patients after percutaneous coronary intervention(PCI).Methods The follow-up plan of artificial intelligence after PCI was constructed through literature review and expert correspondence consultation.A total of 82 patients with coronary heart disease who underwent PCI in the Second Affiliated Hospital of Nanchang University from October 2022 to November 2023 were selected and divided into intervention group and control group according to random number table method,with 41 cases in each group.The control group was given routine nursing program,and the intervention group was added artificial intelligence-based follow-up program on the basis of control group.The incidence of major adverse cardiovascular event(MACE)within 6 months,30 days readmission rate,medication compliance and satisfaction score were compared between two groups.Results The incidence of MACE within 6 months and 30 days readmission rate in intervention group were significantly lower than those in control group(P＜0.05).After 6 months of intervention,Morisky scale score and satisfaction score of patients in two groups were significantly higher than before intervention(P＜0.05),and Morisky scale score and satisfaction score of patients in intervention group were significantly higher than those in control group(P＜0.05).Conclusion Follow-up program based on artificial intelligence technology can reduce the incidence of MACE and 30 days readmission rate of patients after PCI.
