With the rapid development of social economy and the continuous improvement of human living standard, the incidence, fatality and recurrence rates of cardiovascular disease (CVD) are increasing year by year, which seriously affects people's life and health. Conventional therapeutic drugs have limited improvement on the disability rate, so the search for new therapeutic drugs and action targets has become one of the hotspots of current research. In recent years, the therapeutic role of the natural compound rosmarinic acid (RA) in CVD has attracted much attention, which is capable of preventing CVD by modulating multiple signalling pathways and exerting physiological activities such as antioxidant, anti-apoptotic, anti-inflammatory, anti-platelet aggregation, as well as anti-coagulation and endothelial function protection. In this paper, the role of RA in the prevention of CVD is systematically sorted out, and its mechanism of action is summarised and analysed, with a view to providing a scientific basis and important support for the in-depth exploration of the prevention value of RA in CVD and its further development as a prevention drug.

Antibiotic-associated diarrhea(AAD)in children is a type of diarrhea that occurs after the use of antibiotics in children,and its pathogenesis is closely related to the intestinal flora.The medication of antibiotics can affect the metabolic function of the intestinal flora and the immune function of the body,and then leads to the occurrence of AAD.In the view of Chinese medicine,AAD in children is mainly involved the spleen,and the etiology of the disease is due to the weakness of the spleen and stomach of the body constitution together with the attack of the pestilential pathogen and the accumulation of drug toxin.The pathogenesis of ADD in children is characterized by spleen deficiency with predominant dampness,deficiency of spleen qi,and insufficiency of spleen yang.Spleen deficiency is the root cause of pediatric AAD,and spleen and intestinal flora have commonality,so the treatment of pediatric AAD can be performed from the perspective of the spleen.The treatment of pediatric ADD from the spleen follows the principle of strengthening and activating the spleen,and the regulation of the spleen for achieving the purpose of treating the disease from the root can be achieved by the methods of strengthening spleen and draining dampness,strengthening spleen and replenishing qi,and strengthening spleen and warming yang separately with the fundamental prescriptions of Shenlin Baizhu Powder,Sijunzi Decoction,and Fuzi Lizhong Pills.

italic>Platycodon grandiflorum (Jacq.) A. DC is one of the most commonly used bulk medicinal herbs. It has important value in the fields of medicine, food and cosmetics, and its market demand is increasing year by year, and it has a good development prospect. In this study, based on 403 distribution records and 8 environmental variables, we used Maxent model to predict the potential distribution of P. grandiflorum under climate change. The results showed that the model simulation effect was the best when the Maxent parameter was FC (feature combination) = LQPH (L: linear features; Q: quadratic features; P: product features; H: hinge features) and RM (regularization multiplier) = 2.1, AUC (area under curve) = 0.901, and the model prediction showed that P. grandiflorum was widely distributed in 28 provinces of China under the current climate conditions, with a suitable area of 2 337 419.98 km². Under the influence of climate change in the future, the area of suitable habitat of P. grandiflorum showed a decreasing trend, and the distribution center as a whole showed a trend of northward and eastward shift. The distribution area of P. grandiflorum in the three main producing areas is affected by climate change, and the overall trend is that the future suitable distribution area of Chifeng in Inner Mongolia increases, while the future suitable distribution area of Zibo in Shandong and Taihe, Bozhou in Anhui decreases or even disappears under the SSP5-8.5 scenario (shared socioeconomic pathways). It is suggested to maintain and protect the ecological environment and germplasm resources of the reserved area suitable for the growth of P. grandiflorum, and increase the cultivation research in the expansion area of P. grandiflorum, so as to lay a foundation for the subsequent expansion of P. grandiflorum planting and to promote the protection and sustainable development of P. grandiflorum resources.

Objective To investigate the effect of evodiamine on renal fibrosis in rats with chronic renal failure(CRF)by regulating sphingosine kinase 1(SphK1)/S1P signaling pathway.Methods CRF rat model was established by feeding 0.5％adenine diet.The rats after modeling were randomly divided into model group,evodiamine low-and high-dose groups,Niaoduqing Granules group and evodiamine high-dose+K6PC-5(SphK1 activator)group.At the end of intervention,the levels of 24-hour urinary protein(24 h-UTP),serum urea nitrogen(BUN)and serum creatinine(SCr)were detected.The levels of monocyte chemoattractant protein 1(MCP-1)and interleukin 6(IL-6)in serum of rats were detected by enzyme-linked immunosorbent assay(ELISA).The pathological changes of renal tissue and collagen volume fraction(CVF)were observed by hematoxylin-eosin(HE)and Masson staining.The mRNA expressions of transforming growth factor β1(TGF-β1)and type Ⅳcollagen(COL-Ⅳ)in renal tissue were detected by real-time quantitative polymerase chain reaction(qRT-PCR).The protein expressions of SphK1 and S1P in renal tissue were detected by Western Blot.Results Compared with the normal group,the model group showed obvious inflammatory infiltration and collagen fiber deposition,the number of glomeruli decreased in renal tissue,and the expression levels of SCr,BUN,24h-UTP,IL-6,MCP-1,CVF,mRNA expressions of TGF-β1 and COL-Ⅳ,protein expessions of SphK1 and S1P were significantly increased(P＜0.05).Compared with the model group,the histopathological changes of the low-dose and high-dose evodiamine groups and the Niaoduqing Granules group was improved,and the expression levels of SCr,BUN,24 h-UTP,IL-6,MCP-1,CVF,mRNA expressions of TGF-β1 and COL-Ⅳ,protein expessions of SphK1 and S1P were significantly decreased.For intergroup comparison of each index,there were differences between the low-dose evodiamine group and the high-dose evodiamine group(P＜0.05),but there was no significant difference between the high-dose evodiamine group and the Niaoduqing Granules group(P＞0.05).Compared with the high-dose evodiamine group,the histopathological changes of the high-dose evodiamine+K6PC-5 group was further aggravated,and the improvement effect of all indexes were reversed(P＜0.05).Conclusion Evodiamine improves renal fibrosis in CRF rats by inhibiting SphK1/S1P signaling pathway.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To explore the clinical efficacy and influencing factors of omadacycline(OMC)in the treat-ment of patients with infectious diseases.Methods Data about hospitalized patients who received OMC monothera-py or combination therapy at Xiangya Hospital of Central South University from January 2022 to December 2023 were analyzed retrospectively.The influencing factors for failure of OMC treatment was analyzed by univariate and multivariate logistic regression analysis.Results A total of 160 patients were included in analysis,with an overall effective treatment rate of 69.4％(n=111).After treatment with OMC,patients in effective group was observed that body temperature improved([36.83±0.52]℃ vs[37.85±0.92]℃,P＜0.001),white blood cell count([7.78±4.07]× 109/L vs[10.06±6.49]× 109/L,P＜0.001),procalcitonin([0.63±1.19]ng/mL vs[4.43±10.14]ng/mL,P=0.001),C-reactive protein([35.16±37.82]mg/L vs[105.08±99.47]mg/L,P＜0.001),and aspartate aminotransferase([50.50±40.04]U/L vs[77.17±91.43]U/L,P=0.004)all decreased signifi-cantly.Only one patient had adverse reactions such as diarrhea,but treatment was not interrupted.Univariate ana-lysis showed that patients in failure treatment group had a higher acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score(17.0[9.5-22.0]vs 12.0[9.0-19.0],P=0.046)and sequential organ failure assessment(SOFA)score(7.0[4.5-10.0]vs 4.0[2.0-9.0],P=0.019).Multivariate analysis showed that end-stage liver disease(OR=77.691,95％CI:5.448-1 107.880,P=0.001),mechanical ventilation(OR=6.686,95％CI:1.628-27.452,P=0.008)and the combination treatment of vancomycin(OR=6.432,95％CI:1.891-21.874,P=0.003)were risk factors for the failure of OMC treatment,while the course of OMC treatment(OR=0.905,95％CI:0.825-0.994,P=0.037)was a protective factor for the effective treatment.Conclusion OMC can be used as an alternative therapy for refractory severe infection,with fewer adverse reaction.End-stage liver disease,mechanical ventilation and combination treatment of vancomycin are risk factors for failure of OMC treatment in in-fected patients.Adequate OMC treatment course can improve patients'clinical outcome,large-scale case studies are needed to confirm the initial conclusion.

Aim To observe the effect of Astragalus membranaceus and Angelica sinensis on the apoptosis of chondrocytes,and to investigate the effect of Astrag-alus membranaceus and Angelica sinensis on the sur-vival of fresh ostecartilage allograft.Methods Forty-eight 4-month-old New Zealand white rabbits,half male and half female,were randomly divided into sham operation group,model group,positive group and As-tragalus and Angelica 5∶1 group.In addition to the sham operation group,the other groups were both male and female donors and recipients for knee joint osteo-cartilage cross transplantation modeling.After 8 weeks of drug intervention,samples were taken for general observation,HE staining,saffrane-O staining,immu-nohistochemical staining,qPCR and Western blot de-tection.Results Compared with model group,As-tragalus and Angelica 5∶1 group and positive group,the repair site healed better,the morphology of osteo-chondrocytes tended to be normal,and the division and proliferation were obvious.Proteoglycan deposition in-creased and type Ⅱ collagen content was higher,the differences were statistically significant(P＜0.05).qPCR and Western blot results showed that compared with model group,the mRNA and protein expressions of Bax,caspase-3 and caspase-9 in other groups were significantly decreased(P＜0.05).Conclusion As-tragalus and Angelica can promote the survival of fresh osteochondral allograft,and its mechanism may be re-lated to promoting collagen production,promoting chondrocyte proliferation and inhibiting chondrocyte apoptosis.

OBJECTIVE: Huangqi Decoction (HQD), a classical traditional Chinese medicine formula, has been used as a valid treatment for alleviating liver fibrosis; however, the underlying molecular mechanism is still unknown. Although our previous studies showed that microRNA-663a (miR-663a) suppresses the proliferation and activation of hepatic stellate cells (HSCs) and the transforming growth factor-β/small mothers against decapentaplegic (TGF-β/Smad) pathway, whether long noncoding RNAs (lncRNAs) are involved in HSC activation via the miR-663a/TGF-β/Smad signaling pathway has not yet reported. The present study aimed to investigate the roles of lncRNA lnc-C18orf26-1 in the activation of HSCs and the mechanism by which HQD inhibits hepatic fibrosis. METHODS: The expression levels of lnc-C18orf26-1, miR-663a and related genes were measured by quantitative reverse transcription-polymerase chain reaction. HSCs were transfected with the miR-663a mimic or inhibitor and lnc-C18orf26-1 small interfering RNAs. The water-soluble tetrazolium salt-1 assay was used to assess the proliferation rate of HSCs. Changes in lncRNA expression were evaluated in miR-663a-overexpressing HSCs by using microarray to identify miR-663a-regulated lncRNAs. RNA hybrid was used to predict the potential miR-663a binding sites on lncRNAs. Luciferase reporter assays further confirmed the interaction between miR-663a and the lncRNA. The expression levels of collagen α-2(I) chain (COL1A2), α-smooth muscle actin (α-SMA) and TGF-β/Smad signaling pathway-related proteins were determined using Western blotting. RESULTS: Lnc-C18orf26-1 was upregulated in TGF-β1-activated HSCs and competitively bound to miR-663a. Knockdown of lnc-C18orf26-1 inhibited HSC proliferation and activation, downregulated TGF-β1-stimulated α-SMA and COL1A2 expression, and inhibited the TGF-β1/Smad signaling pathway. HQD suppressed the proliferation and activation of HSCs. HQD increased miR-663a expression and decreased lnc-C18orf26-1 expression in HSCs. Further studies showed that HQD inhibited the expression of COL1A2, α-SMA, TGF-β1, TGF-β type I receptor (TGF-βRI) and phosphorylated Smad2 (p-Smad2) in HSCs, and these effects were reversed by miR-663a inhibitor treatment. CONCLUSION Our study identified lnc-C18orf26-1 and miR-663a as promising therapeutic targets for hepatic fibrosis. HQD inhibits HSC proliferation and activation at least partially by regulating the lnc-C18orf26-1/miR-663a/TGF-β1/TGF-βRI/p-Smad2 axis.

OBJECTIVES: To observe the effects of acupoint application with turmeric blistering moxibustion plaster on pain, shoulder range of motion (ROM) and upper limb motor function in the patients with post-stroke hemiplegic shoulder pain (PSHSP). METHODS: Eighty-two patients with PSHSP were randomly divided into an observation group (41 cases, 1 case was eliminated, 4 cases dropped out) and a control group (41 cases, 2 cases were eliminated and 2 cases dropped out). The routine treatment, nursing care and rehabilitation training were performed in the control group. On the basis of the intervention as the control group, in the observation group, the turmeric blistering moxibustion plaster was applied to bilateral ashi points, Jianyu (LI 15), Jianliao (TE 14), Binao (LI 14), Shousanli (LI 10) and Hegu (LI 4), once a day, remained for 6 hours each time. This moxibustion therapy was operated 5 times weekly, one course of treatment consisted of 2 weeks and 2 courses were required. Separately, before treatment and after 2 and 4 weeks of treatment, the score of visual analogue scale (VAS), shoulder ROM and the score of upper limbs in Fugl-Meyer assessment (U-FMA) were observed in the two groups. RESULTS: VAS scores were lower (P<0.05), ROM in shoulder flexion, abduction, internal rotation and external rotation was larger (P<0.05), and U-FMA scores were higher (P<0.05) after 2 and 4 weeks of treatment when compared with those before treatment in the two groups. After 4 weeks of treatment, VAS score decreased (P<0.05), and ROM in shoulder flexion, abduction, internal rotation, external rotation and U-FMA score increased (P<0.05) in comparison with those after 2 weeks of treatment in either group. In the observation group, VAS scores were dropped (P<0.05) after 2 and 4 weeks of treatment respectively, and ROM of shoulder flexion and abduction enlarged after 2 weeks of treatment (P<0.05) when compared with those in the control group. After 4 weeks of treatment, ROM in shoulder flexion, abduction, internal rotation and external rotation in the observation group was larger (P<0.05) and U-FMA score was higher (P<0.05) than those in the control group. CONCLUSIONS Acupoint application with turmeric blistering moxibustion plaster may effectively reduce the degree of shoulder pain and improve the shoulder range of motion and the upper limb motor function in the patients with post-stroke hemiplegic shoulder pain.
