ObjectiveTo study the therapeutic mechanism of Xihuang Wan for hyperplasia of mammary glands based on network pharmacology， molecular docking， and cell experiments. MethodsThe active ingredients and targets of Xihuang Wan were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and A Bioinformatics Annotation daTabase for Molecular mechANism of Traditional Chinese Medicine （BATMAN-TCM） and supplemented by searching against PubChem and Swiss Target Prediction. The targets of differential metabolites in tissues and urine were obtained from previous metabolomics studies through PubChem and Swiss Target Prediction. GeneCards， Online Mendelian Inheritance in Man （OMIM）， PharmGKB， Therapeutic Target Database （TTD）， Drunbank were searched for the targets of hyperplasia of mammary glands. After the common targets were obtained via Veeny2.1.0， the STRING database was used to analyze the protein-protein interactions， and Cytoscape was used for the core target analysis and visualization. Gene Ontology （GO） and the Kyoto Encyclopedia of Genes and Genomes （KEGG） were employed for enrichment analysis. Molecular docking was carried out in Autodock， and cell experiments were conducted to verify the prediction results. In the cell experiments， estradiol and progesterone （E₂+P） were used to intervene in human mammary epithelial/MCF-10A cells， and thus the MCF-10A cell proliferation model was established. The cells were then treated with Xihuang Wan-medicated serum. The cell counting kit-8 （CCK-8） was used to measure the cell proliferation， and flow cytometry was used to detect apoptosis. The mRNA and protein levels of key factors in MCF-10A cells were determined by real-time PCR and Western blot， respectively. ResultsThe results of network pharmacology showed that 90 active ingredients and 316 common targets were obtained， from which 20 core targets and 38 corresponding active ingredients were screened out. The results of GO and KEGG enrichment analyses showed that Xihuang Wan exerted effect against hyperplasia of mammary glands by regulating a variety of biological processes， which may be related to protein kinase B （Akt）-related molecular functions， estrogen signaling pathway， prolactin signaling pathway and other biological processes. The results of molecular docking showed that estrogen receptor 1 （ESR1）， serine/threonine kinase 1 （Akt1）， non-receptor tyrosine kinase （SRC）， and signal transducer and activator of transcription 3 （STAT3） all had strong binding activity with the nine active ingredients， suggesting that Xihuang Wan exert the effect through the ESR1/SRC/phosphatidylinositol 3-kinase （PI3K）/Akt signaling pathway and the Janus kinase （JAK）/STAT3 signaling pathway. The results of cell experiments showed that E₂+P intervention in MCF-10A cells promoted the proliferation of MCF-10A cells （P<0.05）， while the Xihuang Wan-medicated serum inhibited the proliferation of MCF-10A cells exposed to E₂+P （P<0.05）. Flow cytometry showed that the Xihuang Wan-medicated serum promoted the apoptosis of MCF-10A cells exposed to E₂+P （P<0.01）. The results of Real-time PCR showed that the Xihuang Wan-medicated serum down-regulated the mRNA levels of PI3K， Akt， JAK2， and STAT3 in MCF-10A cells treated with E₂+P （P<0.01）. The results of Western blot showed that the Xihuang Wan-medicated serum inhibited the expression of p-PI3K/PI3K， p-Akt/Akt， p-JAK2/JAK2， and p-STAT3/STAT3 in MCF-10A cells treated with E₂+P （P<0.05）. ConclusionXihuang Wan may exert the effect against hyperplasia of mammary glands by inhibiting the proliferation and promoting the apoptosis of MCF-10A cells， which may related to the inhibition of the activation of PI3K/Akt and JAK2/STAT3 signaling pathways.

Xihuang pills are a classic Chinese patent medicine following the theoretical principle of combining eliminating pathogen with reinforcing healthy qi in both local areas and the whole body， with the effects of clearing heat， detoxifying， alleviating edema， and dissipating mass. This medicine is traditionally used for treating carbuncle， furuncle， multiple abscess， carcinoma of breast， phlegm nodule， scrofula， lung abscess， and intestine abscess caused by fire depression， phlegm stasis， and heat toxin stagnation. It is used for treating malignant tumors， breast hyperplasia， herpes zoster， lymphadenitis， pelvic inflammatory disease， mastitis， vocal cord leukoplakia， and acne in modern medicine. Xihuang pills are now included in the 2020 edition of the Chinese Pharmacopoeia. The use of high-quality medicinal materials and modern technology enables full retaining of the active components in the medicinal materials. The chemical components in this medicine mainly include amino acids， terpenoids， fatty acids， fatty acid esters， phenols， bile acids， bile pigments， and volatile oils. Modern pharmacological studies have shown that a variety of active components such as bilirubin， bile acid， boswellic acid， and volatile oil in Xihuang pills interact with each other to exert anti-tumor， anti-breast hyperplasia， immunomodulatory， anti-inflammatory， and neuroendocrine-regulating effect. This paper reviews the research progress in the active components and pharmacological effects of Xihuang pills and predicts the quality markers （Q-markers） of this medicine according to the transmission， traceability， specificity， efficacy， measurability， and compound compatibility in the concept of Q-marker. It is suggested that bilirubin， bile acid， taurine， muskone， 11-carbonyl-β-boswellic acid， β-boswellic acid， 3-acetyl-11-keto-β-boswellic acid， octyl acetate， β-elemene， and myrrhone can be used as Q-markers of Xihuang pills， which can provide a basis for research on the material basis and the quality control of Xihuang pills.

Objective:To observe the clinical efficacy of neck Gongfa exercise in intervening people at high risk for cervical spondylosis. Methods:A total of 212 participants from 8 companies at high risk for cervical spondylosis were divided into two groups using the random number table method,with 105 participants in the control group receiving health education and 107 participants in the trial group receiving an additional neck Gongfa exercise.After successive 3-month interventions,the two groups were compared in terms of cervical soft tissue tension and neck disability index(NDI)score.The incidence of cervical spondylosis was observed 3 months later. Results:During the process,10 cases dropped out in the trial group,and the control group had 9 dropout cases.After the intervention,the cervical soft tissue tension value and NDI score improved in both groups(P<0.05)and showed significant differences between the two groups(P<0.05).At the 3-month follow-up,the trial group had a lower incidence rate of cervical spondylosis than the control group(P<0.05). Conclusion:For people at high risk for cervical spondylosis,neck Gongfa exercise can effectively improve cervical soft tissue tension and motor dysfunction and lower the incidence of cervical spondylosis in the short run.

Esophageal squamous cell carcinoma (ESCC) is a kind of malignant tumor with high incidence and mortality in the digestive system. The aim of this study is to explore the function of lnc-ABCA12-3 in the development of ESCC and its unique mechanisms. RT-PCR was applied to detect gene transcription levels in tissues or cell lines like TE-1, EC9706, and HEEC cells. Western blot was conducted to identify protein expression levels of mitochondrial apoptosis and toll-like receptor 4 (TLR4)uclear factor kappa-B (NF-κB) signaling pathway. CCK-8 and EdU assays were carried out to measure cell proliferation, and cell apoptosis was examined by flow cytometry. ELISA was used for checking the changes in glycolysis-related indicators.Lnc-ABCA12-3 was highly expressed in ESCC tissues and cells, which preferred it to be a candidate target. The TE-1 and EC9706 cells proliferation and glycolysis were obviously inhibited with the downregulation of lnc-ABCA12-3, while apoptosis was promoted. TLR4 activator could largely reverse the apoptosis acceleration and relieved the proliferation and glycolysis suppression caused by lnc-ABCA12-3 downregulation. Moreover, the effect of lnc-ABCA12-3 on ESCC cells was actualized by activating the TLR4/NF-κB signaling pathway under the mediation of exosome. Taken together, the lnc-ABCA12-3 could promote the proliferation and glycolysis of ESCC, while repressing its apoptosis probably by regulating the TLR4/NF-κB signaling pathway under the mediation of exosome.

OBJECTIVES: To compare the short-, mid-, and long-term outcomes in patients with esophageal cancer between minimally invasive esophagectomy via Sweet approach in combination with cervical mediastinoscopy (MIE-SM) and minimally invasive esophagectomy via McKeown approach (MIE-MC), and to evaluate the value of MIE-SM in the surgical treatment of esophageal cancer. METHODS: A prospective, nonrandomized study was adopted. A total of 65 esophageal cancer patients after MIE-SM and MIE-MC from June 2014 to May 2016 were included. Among them, 33 patients underwent MIE-SM and 32 patients underwent MIE-MC. Short-term outcomes (including the duration of surgery, intraoperative blood loss volume, ICU stay time, postoperative complications, postoperative hospital stay, reoperation, open surgery, number of dissected lymph nodes, and 30-day mortality), mid-term outcomes, [including Quality of Life Core Questionnaire (QLQ-C30) and the esophageal site-specific module (QLQ-OES18)], long-term outcomes [including overall survival and disease-free survival] were compared between the 2 groups. RESULTS: Radical resection (R0) were achieved in all patients. There were no significant differences in the duration of surgery, intraoperative blood loss volume, ICU stay time, postoperative complications, and postoperative hospital stay between the 2 groups (all CONCLUSIONS MIE-SM appears to be a safe surgical approach, which may get better quality of life, suffer less pain, and can achieve the same therapeutic effect as MIE-MC. Therefore, MIE-SM should be considered as a valuable approach for the treatment of middle and lower esophageal cancer.

Objective:To investigate the characteristics of videonystagmography (VNG) in multiple system atrophy (MSA) patients with vertigo as the main symptom.Methods:Twenty-eight MSA patients and 28 healthy volunteers were selected, and their basic clinical data, namely, gender, age of onset, course of disease, initial symptoms, and clinical manifestations, were collected. VNG was adopted to measure spontaneous nystagmus and carry out gaze test, saccade test, smooth tracking test, visual movement test, position test, and temperature test.Results:Among the MSA patients with vertigo as the main symptom, the number of MSA-C (the cerebellar type) cases ( n=22) was significantly higher than that of MSA-P (the parkinsonian type) cases ( n=6), and there was no statistically significant difference in gender, age of onset, and course of disease ( P>0.05). The incidence of gaze nystagmus was 45.5% (10/22) in the MSA-C group and 33.3% (2/6) in the MSA-P group, which were significantly higher than that in the control group ( P<0.05). The abnormal rate of saccade test was which were significantly higher than that in the control group ( P<0.05). The abnormal rate of saccade test was 36.4% (8/22) in the MSA-C group, and no abnormality was found in the MSA-P group and the control group. The rate of abnormal visual tracking was 77.3% (17/22) in the MSA-C group and 83.3% (5/6) in the MSA-P group, which were significantly higher than that of the control group ( P<0.05). The rate of decreased optokinetic nystagmus (OKN) or nystagmus asymmetry was 40.9% (9/22) in the MSA-C group and 83.3% (5/6) in the MSA-P group, which were significantly higher than that of the control group ( P<0.05). The abnormal rate of position test was 22.7% (5/22) in the MSA-C group and 33.3% (2/6) in the MSA-P group, which showed no statistically significant difference when compared with that of the control group ( P>0.05). In the temperature test, the abnormal rate of unilateral weakening was 22.7% (5/22) in the MSA-C group, which was significantly higher than those in the MSA-P group and the control group. The hyperresponsiveness rate of cold and heat stimulation was 4.5% (1/22) in the MSA-C group, while there was no hyperresponsiveness in both the MSA-P group and the control group. The failure rate of fixation inhibition was 63.6% (14/22) in the MSA-C group, and there was no failure in the control group. Conclusion:In MSA patients with vertigo as the main symptom, the incidence of abnormal eye movements, especially the symptoms of visual tracking abnormality, fixation inhibition failure, and gaze nystagmus, is relatively high. The results of this analysis can help clinical diagnoses.
