Hyssopus cuspidatus is an authentic medicinal herb used in Xinjiang， rich in the chemical constituents including flavonoids， phenolic acids and terpenoids. It possesses anti-inflammatory， antioxidant， and immunomodulatory effects. Modern pharmacological studies have demonstrated that H. cuspidatus exerts therapeutic effects on asthma by inhibiting airway inflammatory responses， suppressing airway remodeling， modulating the function of the hypothalamic-pituitary-adrenal axis， and relaxing bronchial smooth muscle. It also demonstrates intervention effects on chronic obstructive pulmonary disease by reducing levels of inflammatory cytokines and regulating immune balance. Additionally， H. cuspidatus can mitigate acute lung injury by inhibiting oxidative stress and intervene in lung cancer by suppressing proliferation and promoting apoptosis of lung cancer cells. In terms of clinical application， compound preparations containing H. cuspidatus， such as Hanchuan zupa granules and Luo’ou kezupa， have demonstrated favorable therapeutic effects on pulmonary diseases including asthma， cough， and pediatric bronchopneumonia. Currently， the research on precise action targets and compound matching rules of H. cuspidatus remains inadequate. Future studies should integrate modern technologies such as metabolomics to conduct in-depth exploration， thereby promoting the modernized development and clinical application of this traditional medicinal herb.

ObjectiveTo investigate the effect of Naoqingtong decoction （NQT） on the kidney damage and the inflammatory factors NOD-like receptor protein 3 （NLRP3）， apoptosis-associated speck-like protein containing a C-terminal caspase recruitment domain （ASC）， cysteinyl aspartate-specific proteinase-1 （Caspase-1）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） in spontaneously hypertensive rats （SHRs）. MethodsTwenty-four SHRs were randomized into a model group， a low-dose （12.9 g·kg^-1·d^-1） NQT （NQT-L） group， a high-dose （25.8 g·kg^-1·d^-1） NQT group （NQT-H）， and a captopril （CTP， 20 mg·kg^-1·d^-1） group， with 6 rats in each group. In addition， 6 homozygous male Wistar-Kyoto rats were used as the control group. The control and model groups were administrated with the same amount of normal saline by gavage for 8 weeks. General behaviors of rats were observed during the intervention period， and the blood pressure was measured periodically. At the end of intervention， the body mass was weighed， and both kidneys were collected and weighed for the calculation of the renal index. Hematoxylin-eosin staining was performed to observe the pathological changes in the kidney tissue. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot were employed to determine the expression levels of NLRP3， ASC， Caspase-1， IL-6， and TNF-α in the kidney tissue. ResultsDuring the experiment period， the control group had normal mental status， food intake， and activity， while the model group showed thinning of hair， loss of luster， reduced activity， loss of appetite， fecal adhesion， and irritability， and some of the skin had scratches or blood scabs. The above symptoms were alleviated to different degrees after 8 weeks of NQT administration. An intelligent non-invasive sphygmomanometer was used to measure the tail artery pressure of rats， which showed that the systolic and diastolic blood pressure of rats in the model group was higher than that in the control group （P<0.01）. Compared with the model group， drug interventions lowered the systolic and diastolic blood pressure （P<0.05， P<0.01）. Compared with the control group， the model group showed severe pathological damage in the kidney tissue， which was alleviated in each drug intervention group. Compared with the control group， the model group showed up-regulated expression levels of NLRP3， ASC， Caspase-1， IL-6， and TNF-α in the kidney tissue （P<0.05， P<0.01）. Compared with the model group， the drug intervention groups showed down-regulated expression levels of NLRP3， ASC， Caspase-1， IL-6， and TNF-α in the kidney tissue （P<0.05， P<0.01）. ConclusionNQT can lower the blood pressure in SHRs by inhibiting the activation of NLRP3 inflammasomes， suppressing renal inflammation， and ameliorating hypertensive kidney damage.

OBJECTIVE:To study the mechanism of Aurantii fructus immaturus(AFI)and its main active ingredients in pro-moting gastrointestinal motility of model rats with spleen deficiency. METHODS:170 rats were randomly divided into blank group (10 rats) and modeling group (160 rats),rats in modeling group was induced models with spleen deficiency by bitter cold diar-rhea+irregular diet. After modeling, rats were randomly divided into model group, naringin (NA) low-dose, medium-lose, high-dose groups(3.267,6.535,13.070 mg/mL),neohesperidin(NE)low-dose,medium-lose,high-dose groups(3.865,7.730, 15.460 mg/mL),synephrine(SY)low-dose,medium-lose,high-dose groups(0.252,0.504,1.008 mg/mL),compatibility groups with 3 monomer ingredients (NA-NE-SY) low-dose,medium-lose,high-dose and AFI water decoction low-dose,medium-lose, high-dose groups(0.104,0.208,0.416 g/mL,calculated by crude drug),ig,once a day,10 mL/kg,for 7 d. After the last admin-istration,gastrin (GAS) in serum,and acetylcholine (ACh),motilin (MTL),substance P (SP),vasoactive intestinal peptide (VIP)levels in plasma were detected. RESULTS:Compared with blank group,GAS level in serum and ACh,MTL,SP levels in plasma in model group were reduced(P<0.01),VIP level in plasma was increased(P<0.05). Compared with model group,ex-cept for the GAS level in serum showed no obvious change in NA high-dose group and SY doses groups,other medicine groups were obviously increased (P<0.05 or P<0.01);the ACh levels in serum were obviouly increased in NE high-dose group,SY high-dose group and AFI water decoction low-dose group(P<0.01). MTL levels in plasma were obviously increased in NE medi-um-dose,high-dose groups,SY high-dose group,compatibility low-dose,medium-dose groups and AFI water decoction medi-um-dose,high-lose groups (P<0.05);SP levels in plasma were obviously increased in NA low-dose,medium-dose groups and NE doses groups(P<0.05 or P<0.01);VIP levels were reduced in NA low-dose group,SY high-dose group and AFI water decoc-tion low-dose,medium-lose groups(P<0.05). CONCLUSIONS:AFI may promote the gastrointestinal motility of model rats with spleen deficiency by promoting the secretion of GAS,ACh,MTL,and inhibiting the secretion of VIP;there are differences be-tween AFI and the 3 monomer ingredients in regulation of gastrointestinal hormones.
