OBJECTIVE To explore the effect and mechanism of Zexie tang （ZXT） on reducing lipid accumulation through network pharmacology， and compare the difference of traditional decoction versus formula granules. METHODS The active components and targets of ZXT were identified using TCMSP and SwissTargetPrediction databases. GeneCards， OMIM， DisGeNET and TTD databases were used to analyze the related targets of non-alcoholic fatty liver disease （NAFLD）； protein-protein interaction network model was constructed by String database；“ ZXT-NAFLD target-pathway” network diagram was constructed by using CytoScape software； target enrichment analysis was performed by using Metascape platform. Fat accumulation model of human hepatocellular carcinoma HepG2 cells was established to observe the effects of traditional decoction and formula granules of ZXT on lipid accumulation of cells. RESULTS Alisol B， alisol C， 1-monolinolein and alisol B monoacetate were the key active components of ZXT in the treatment of NAFLD. The core targets included MDM2， MAPK1， PIK3CB， PRKCQ and MAPK14， etc. The core signaling pathways included endocrine resistance， insulin resistance and Th17 cell differentiation. Compared with model group， except for the Zexie formula granules group and Baizhu formula granules group， the absorbance values in all other administration groups were significantly decreased （P＜0.01）； the absorbance value of Baizhu traditional decoction group was significantly higher than that of ZXT traditional decoction group （P＜0.01）； the absorbance values of Zexie formula granule group and Baizhu formula granule group were significantly higher than that of ZXT formula granule group （P＜0.01）； the absorbance value of Zexie formula granule group was significantly higher than that of Zexie traditional decoction group （P＜0.01）； the absorbance value of Baizhu formula granule group was significantly higher than that of Baizhu traditional decoction group （P＜0.01）. CONCLUSIONS ZXT reduces lipid accumulation of human hepatocellular carcinoma cells through multiple components， multiple target and multiple pathways， and its traditional decoction and formula granules exhibit slightly different lipid-lowering effects.

Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine （TCM） mainly involves peripheral vestibular diseases of Western medicine， such as Meniere's disease， benign paroxysmal positional vertigo， vestibular neuritis， and vestibular migraine， being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo， aural vertigo affecting the quality of life， aural vertigo not relieved after surgery， aural vertigo with complex causes， and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM： Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo， the control and mitigation of the symptoms， and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.

[Objective]To investigate the effect and mechanism of Shuxuetong and its main component hirudin on the apoptosis of cerebellar granule neurons(CGNs)in Sprague-Dawley(SD)rats.[Methods]CGNs incubated in vitro for 7 days were divided into survival control group or 25 K group(cultured in medium containing 25 mmol/L KCL)and apopto-sis group or 5 K group(cultured in medium containing 5 mmol/L KCL).CGNs were separately treated with proportionally diluted and different concentrations of Shuxuetong(1/50,1/40,1/30,1/20 and 1/10)and the corresponding different con-centrations of hirudin(2,2.5,3.34,5 and 10 U/mL).Hoechst staining was performed to analyze the apoptosis.Western blot was used to detect the expression levels of Cleaved Caspase-3,Bim and VEGF.[Results]Hoechst staining showed that 5 K group had a higher apoptosis rate than 25 K group.In 25 K group,there was no significant change in the apoptosis rate between neurons treated with different concentrations of Shuxuetong and hirudin,but significant changes was found in 5 K group and the higher the concentration,the lower the apoptosis rate.Western blot results revealed that,compared with control neurons in 5 K group,Shuxuetong injection and hirudin treatments resulted in a decrease of Cleaved Caspase-3 and Bim expression,but an increase of VEGF protein.[Conclusions]Shuxuetong and its main component hirudin inhibits the apoptosis of CGNs through suppressing proapoptotic BH3-only protein Bim.

Based on ZHU Zhenheng's “six constraints” theory， it is proposed that the formation of pulmonary nodules is closely related to the six constraints， which are constraint of qi， blood， phlegm， fire， dampness and food. All six constraints might lead to pulmonary nodules， among which qi constraint is the dominant one. When qi constraint lasts for a long time， it will turn into fire constraint， resulting in the failure of spleen to transport， which may lead to phlegm constraint， dampness constraint and food constraint； when qi fails to move blood， blood constraint is formulated. Mutual generation of six constraints lead to the disease， and the pathogenesis is interrelated， jointly promoting the occurrence and development of pulmonary nodules. The treatment is mainly to unblock qi， usually using Yueju Pills （越鞠丸）， a classic formula commonly used for six constraints， as the basic formula. And according to the six constraints partiality， it is suggested to flexibly add the medicinals of soothing the liver and rectifying qi， clearing heat and dissipating masses， dissolving phlegm and dissipating masses， fortifying spleen and dissipating dampness， promoting digestion and removing accumulation， invigorating blood and dissolving stasis.

We reported a case of microcephaly-capillary malformation(MIC-CAP)caused by STAMBP gene variant,in order to improve the clinical diagnosis and treatment.The patient is a 3-month-old male with recurrent convulsions and the main clinical manifestations are multiple forms of seizures,microcephaly,multiple small capillary malformations in the skin,and generalized hypotonia.The genetic test showed that a heterozygous variant in the STAMBP gene was present in the child.Both parents were heterozygous carriers.He was administrated various anti-seizure medications and ketogenic diet,but still had frequent seizures.He then underwent corpus callosotomy,and was followed up until he was 4 years and 10 months old.The post operational outcome was grade IV on Engel's classification.Based on the clinical data of 22 patients in literature,in addition to severe psychomotor retardation,microcephaly,and cutaneous capillary malformations,early-onset drug-refractory epilepsy is also a major feature of MIC-CAP syndrome,which is clinically rare and has a poor prognosis;Callosotomy may help to reduce seizures in the short term.However,the long-term outcome is poor.STAMBP gene is the main responsible gene for this syndrome.

ObjectiveTo observe the protective effect of Chaihu Jia Longgu Mulitang （CLMT） on dopaminergic neurons in Parkinson's disease with depression （PDD） model rats， and to explore the mechanism based on adenosine monophosphate-activated protein kinase/mammalian target of rapamycin （AMPK/mTOR） signaling pathway. MethodAmong the 80 male SD rats， 10 were randomly selected as normal group and the rest were treated with long-term low-dose subcutaneous injection of rotenone in the neck and back combined with chronic unpredictable mild stress （CUMS） to establish PDD rat model. The successfully modeled PDD rats were randomly divided into model group， western medicine group （madopar 0.032 g·kg^-1+fluoxetine hydrochloride 0.002 g·kg^-1）， CLMT low-dose， medium-dose and high-dose groups （5， 10 and 20 g·kg^-1）， 10 rats in each group. Normal group and model group were administrated with the same amount of normal saline by gavage for 4 consecutive weeks. Behavioral changes of rats in each group were evaluated by open field test and pole climbing test. The content of dopamine （DA） and 5-hydroxytryptamine （5-HT） in cerebrospinal fluid was determined by high performance liquid chromatography （HPCL）. The pathological changes of dopaminergic neurons in substantia nigra of rats were observed by hematoxylin-eosin （HE） staining. The positive expression of tyrosine hydroxylase （TH） and expression of α-synuclein in substantia nigra were detected by immunohistochemistry （IHC） and immunofluorescence （IF）， repsectively. The protein expression of microtubule-associated protein 1 light chain 3 （LC3）， adenosine monophosphate-activated protein kinase （AMPK）， phosphorylated AMPK （p-AMPK）， mammalian target of rapamycin （mTOR） and phosphorylated mTOR （p-mTOR） was detected by Western blot. ResultCompared with the conditions in normal group， the total horizontal distance and the activity time in the central region in open field test and the content of DA and 5-HT in cerebrospinal fluid were decreased （P<0.05， P<0.01）， and the time of pole climbing was shortened （P<0.01）， with increased score （P<0.01） in model group. Compared with model group， CLMT high-dose group and western medicine group increased the total horizontal distance and activity time in the central region and the content of DA and 5-HT （P<0.05， P<0.01）， and extended the time of climbing pole （P<0.05）， with decreased score （P<0.05， P<0.01）. Compared with those in normal group， the number of dopaminergic neurons in the substantia nigra was reduced， with narrowed and loosely arranged cell body. The fluorescence expression of α-synuclein was enhanced （P<0.01）， and the positive expression of TH was decreased （P<0.01） in model group. Compared with model group， CLMT high-dose group and western medicine group showed elevated number of dopaminergic neurons in the substantia nigra， with enlarged cell body， and decreased fluorescence expression of α-synuclein， and enhanced the positive expression of TH （P<0.05， P<0.01）. Compared with normal group， model group had lowered expression of LC3Ⅱ/Ⅰ， p-AMPK/AMPK in striatum （P<0.05， P<0.01） and increased expression of p-mTOR/mTOR （P<0.01）. Compared with those in model group， LC3Ⅱ/Ⅰ and p-AMPK/AMPK expression were increased （P<0.05， P<0.01） and p-mTOR /mTOR expression was decreased （P<0.01） in CLMT high-dose group and western medicine group. ConclusionCLMT exerts a neuroprotective effect by inhibiting rotenone neurotoxicity. It enhances the level of DA， and thus improves the depression condition in rats with Parkinson's disease. The underlying mechanism may be related to the regulation of AMPK/mTOR signaling pathway， activation of autophagy， and promotion of degrading α-synuclein.

Objective:To explore the potential mechanism of Qingke Pingchuan granule in treating acute and chronic bronchitis complicated with chronic obstructive pulmonary disease （COPD） by network pharmacology. Method:The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） was retrieved to collect the active components of Qingke Pingchuan granule and predict the action targets， followed by the construction of component-target network using Cytoscape 3.8. GeneCards， Online Mendelian Inheritance in Man（OMIM）， and DrugBank were used to harvest disease targets， whose names were put into UniProt for standardization. The treatment targets of Qingke Pingchuan Granule against the two diseases were obtained based on Venn diagram， which were then imported into the STRING platform for constructing the protein-protein interaction （PPI） network. Following the gene ontology（GO） and Kyoto encyclopedia of genes and genomes（KEGG） pathway enrichment analysis based on MetaScape， the active component-common target-signaling pathway network of Qingke Pingchuan granule against acute and chronic bronchitis complicated with COPD was finally constructed. The accuracy of the target was confirmed by literature. Result:A total of 165 active components， 374 related targets， 512 disease-related targets， and 130 common targets were obtained. Among them， the 14 core therapeutic targets were further subjected to GO enrichment analysis， which yielded 390 biological processes， nine cell components， and 23 molecular functions. The KEGG pathway analysis revealed 22 signaling pathways. Conclusion:Qingke Pingchuan granule alleviates the diseases possibly by regulating such targets as vascular endothelial growth factor receptor 2（KDR）， transforming growth factor beta-1 （TGF-β₁）， caveolin 1（CAV1）， hypoxia-inducible factor-1alpha（HIF-1α）， and interleukin-2（IL-2）， affecting the synthesis and transport of regulatory factors in cytoplasm， and controlling the cell proliferation and apoptosis.
