Effect of Gupi Xiaoji Decoction on mitochondrial structure and function of human hepatoma cell line HepG2 / 中国药理学通报

Aim To observe the effect of Gupi Xiaoji Decoction (GPXJY) on the structure and function of mitochondria of human hepatoma cell HepG2 cells and explore its possible mechanism. Methods CCK8 was used to detect cell proliferation, Mito-Tracker Green fluorescence staining was used to observe the mitochondrial structure, flow cytometry was used to detect the membrane potential, Elisa was used to detect the ATP content, fluoroscopic electron microscopy was used to observe the microstructure changes, and high-content screening(HCS) was used to detect the related proteins. Results Fluorescence staining showed that GPXJY damaged the mitochondria of HepG2 cells and decreased the content of ATP. The results of flow cytometry showed that GPXJY could reduce the mitochondrial membrane potential of HepG2 cells. The results of electron microscope showed that GPXJY made the mitochondria of cancer cells swell and so on. HCS found that GPXJY significantly reduced the average fluorescence intensity of Bcl-2 in HepG2 cells, and significantly increased the average fluorescence intensity of apoptosis promoting proteins Bax, cytochrome-c, caspase-3 and cleaved-caspase-3, which was statistically significant. Conclusion GPXJY can regulate the structure and function of mitochondria in HepG2 cells.

Effects of Xihuang Pills on proliferation and apoptosis of prostate cancer LNCaP cells based on AR/m TOR signaling pathway / 中国中药杂志

Based on the androgen receptor(AR)/mammalian target of rapamycin(mTOR)signaling pathway, the effects of Xihuang Pills-medicated serum on the proliferation and apoptosis of prostate cancer LNCaP cells were investigated. The drug-containing serum of SD rats was prepared by intragastric administration of Xihuang Pills suspension. The effects of low-, medium-, and high-dose Xihuang Pills-containing serum on the in vitro proliferation of LNCaP cells were detected by cell counting kit-8(CCK-8). Flow cytometry was used to detect the apoptosis level of LNCaP cells after intervention with different concentrations of Xihuang Pills. Protein expression of cleaved cysteinyl aspartate-specific proteinase caspase-3(cleaved caspase-3), B-cell lymphoma-2(Bcl-2), and AR as well as the phosphorylation level of mTOR protein were detected by Western blot. The results showed that compared with the blank serum, the drug-medicated serum could blunt the activity of LNCaP cells. Low-, medium-, and high-dose Xihuang Pills-containing serum could significantly increase the cell apoptosis rate, increase the expression of cleaved caspase-3 protein, decrease the expression of Bcl-2 protein, reduce the expression of AR protein, and down-regulate the level of phosphorylated mTOR(p-mTOR). To study the effect of Xihuang Pills on the growth of LNCaP cells in vivo, different doses of Xihuang Pills were used to intervene in the subcutaneous graft model in nude mice inoculated with LNCaP cells. The expression levels of AR, mTOR, p-mTOR, Bcl-2, and cleaved caspase-3 were detected by Western blot. The results showed that the volumes of subcutaneous graft tumor in the low-dose, medium-dose, and high-dose Xihuang Pills groups significantly decreased compared with that in the model group. The weight of subcutaneous transplanted tumor in each group with drug intervention was significantly lower than that in the model group. Compared with the model group, the low-dose, medium-dose, and high-dose Xihuang Pills groups showed increased cleaved caspase-3 protein expression, decreased Bcl-2 and AR protein expression, and reduced p-mTOR protein expression. Further experiments showed that AR agonist R1881 could block the anti-proliferation and pro-apoptotic effects of Xihuang Pills. The mechanism of Xihuang Pills against prostate cancer is related to the inhibition of the AR/mTOR signaling pathway, inhibition of LNCaP cell proliferation, and induction of apoptosis in cancer cells.

Short-term effect evaluation of self-management group projects for chronic disease patients in Suzhou / 公共卫生与预防医学

Objective To evaluate the short-term effect of self-management group project for chronic disease patients in Suzhou. Methods Eight to ten streets / towns were randomly selected from 10 cities and districts under the jurisdiction of Suzhou. Each street / town set up a chronic disease self-management group and carried out group activities. The awareness rate of chronic disease related knowledge, health management behavior and health status of the group members after and before the activities were compared to evaluate the short-term effect of the self-management group project. Results A total of 89 chronic disease self-management groups were set up in Suzhou in 2020. Among them, there were 47 hypertension groups and 42 diabetes groups. A total of 1176 people were surveyed at baseline, and 1161 people participated in the evaluation survey after the group activities. By setting up self-management groups, the awareness rates of chronic disease-related knowledge (BMI range, variety of food intake per day per week, moderate-intensity activity time per week, daily salt intake, harm of excessive salt intake, diagnostic criteria for hypertension, sodium content in low sodium salt, fasting blood glucose criteria, low-density lipoprotein control targets) in hypertension and diabetes patients after the intervention were improved compared with those before the intervention, and the differences were statistically significant (P“self-monitoring blood pressure” increased from 52.80% before the intervention to 66.32%, while the proportion of "having a blood glucose monitoring system at home" increased from 52.80% before the intervention to 66.32%, and the proportion of “self-monitoring blood glucose” increased from 25.67% before the intervention to 38.67%. The percentage of "drinking alcohol in the past 30 days" dropped from 12.14% before the intervention to 8.35%. All these differences were statistically significant. There was no difference in the number of "smoking in the past 30 days" compared with before the activity (P≥0.05). The number of days with poor health resulting from injuries in the past 30 days also decreased but the difference was not statistically significant (P≥0.05). In terms of the severity of depression, the number of people with moderate and severe depression decreased after the intervention, and the number of people who turned into mild depression increased, and the difference was statistically significant (P<0.05). Conclusion The self-management group project for chronic disease patients in Suzhou has achieved good results and is suitable for continued promotion and application in this region.

Depression status of elderly patients with metabolic syndrome in three provinces of China / 中华流行病学杂志

Objective: To understand the depression status and its influencing factors in elderly patients with MS in China and to explore the correlation between various components of elderly MS and depression. Methods: This study is based on the "Prevention and Intervention of Key Diseases in Elderly" project. We used a multi-stage stratified cluster random sampling method to complete 16 199 elderly aged 60 years and above in 16 counties (districts) in Liaoning, Henan, and Guangdong Provinces in 2019, excluding 1 001 missing variables. Finally, 15 198 valid samples were included for analysis. The respondents' MS disease was obtained through questionnaires and physical examinations, and the respondents' depression status within the past half month was assessed using the PHQ-9 Depression Screening Scale. The correlation between elderly MS and its components and depression and its influencing factors were analyzed by logistic regression. Results: A total of 15 198 elderly aged 60 years and above were included in this study, with the prevalence of MS at 10.84% and the detection rate of depressive symptoms in MS patients at 25.49%. The detection rates of depressive symptoms in patients with 0, 1, 2, 3, and 4 MS abnormal group scores were 14.56%, 15.17%, 18.01%, 25.21%, and 26.65%, respectively. The number of abnormal components of MS was positively correlated with the detection rate of depressive symptoms, and the difference between groups was statistically significant (P<0.05). The risk of depression symptoms in patients with MS, overweight/obesity, hypertension, diabetes, and dyslipidemia was 1.73 times (OR=1.73, 95%CI:1.51-1.97), 1.13 times (OR=1.13, 95%CI:1.03-1.24), 1.25 times (OR=1.25, 95%CI:1.14-1.38), 1.41 times (OR=1.41, 95%CI:1.24-1.60), 1.81 times (OR=1.81,95%CI:1.61-2.04), respectively, more than those without the disease. Multivariate logistic regression analysis showed that the detection rate of depressive symptoms in patients with sleep disorders was higher than that with normal sleep (OR=4.89, 95%CI: 3.79-6.32). The detection rate of depressive symptoms in patients with cognitive dysfunction was 2.12 times higher than that in the average population (OR=2.12, 95%CI: 1.56-2.89). The detection rate of depressive symptoms in patients with impaired instrumental activities of daily living (IADL) was 2.31 times (OR=2.31, 95%CI: 1.64-3.26) higher than that in the average population. Tea drinking (OR=0.73, 95%CI: 0.54-0.98) and physical exercise (OR=0.67, 95%CI: 0.49-0.90) seemed to be protective factors for depression in elderly MS patients (P<0.05). Conclusions: Older patients with MS and its component abnormalities have a higher risk of depression than the average population. Sleep disorders, cognitive impairment, and IADL impairment are important influencing factors for depression in elderly MS patients, while tea drinking and physical exercise may help to reduce the risk of the disease.

Pathological significance of plasma cell infiltration in diagnosing lymph node diseases / 中华病理学杂志

Objective: To investigate the value of plasma cells for diagnosing lymph node diseases. Methods: Common lymphadenopathy (except plasma cell neoplasms) diagnosed from September 2012 to August 2022 were selected from the pathological records of Changhai Hospital, Shanghai, China. Morphological and immunohistochemical features were analyzed to examine the infiltration pattern, clonality, and IgG and IgG4 expression of plasma cells in these lymphadenopathies, and to summarize the differential diagnoses of plasma cell infiltration in common lymphadenopathies. Results: A total of 236 cases of lymphadenopathies with various degrees of plasma cell infiltration were included in the study. There were 58 cases of Castleman's disease, 55 cases of IgG4-related lymphadenopathy, 14 cases of syphilitic lymphadenitis, 2 cases of rheumatoid lymphadenitis, 18 cases of Rosai-Dorfman disease, 23 cases of Kimura's disease, 13 cases of dermal lymphadenitis and 53 cases of angioimmunoblastic T-cell lymphoma (AITL). The main features of these lymphadenopathies were lymph node enlargement with various degrees of plasm cell infiltration. A panel of immunohistochemical antibodies were used to examine the distribution of plasma cells and the expression of IgG and IgG4. The presence of lymph node architecture could help determine benign and malignant lesions. The preliminary classification of these lymphadenopathies was based on the infiltration features of plasma cells. The evaluation of IgG and IgG4 as a routine means could exclude the lymph nodes involvement of IgG4-related dieases (IgG4-RD), and whether it was accompanied by autoimmune diseases or multiple-organ diseases, which were of critical evidence for the differential diagnosis. For common lesions of lymphadenopathies, such as Castleman's disease, Kimura's disease, Rosai-Dorfman's disease and dermal lymphadenitis, the expression ratio of IgG4/IgG (>40%) as detected using immunhistochemistry and serum IgG4 levels should be considered as a standard for the possibility of IgG4-RD. The differential diagnosis of multicentric Castleman's diseases and IgG4-RD should be also considered. Conclusions: Infiltration of plasma cells and IgG4-positive plasma cells may be detected in some types of lymphadenopathies and lymphomas in clinicopathological daily practice, but not all of them are related to IgG4-RD. It should be emphasized that the characteristics of plasma cell infiltration and the ratio of IgG4/IgG (>40%) should be considered for further differential diagnosis and avoiding misclassification of lymphadenopathies.

Objective To investigate the EMG characteristics and clinical application value of surface EMG in cervical muscle group of children with congenital muscular torticollis(CMT).Methods A retrospective analysis was performed on 478 children diagnosed as CMT from January 2018 to August 2022 in Rehabilitation Center of the Children's Hospital Affiliated to Chongqing Medical University.The torticollis side of the same case was included in observation group and the healthy side was included in control group.Surface EMG was used to record the electromyography root-mean-square values of bilateral sternocleidomastoid muscles,platysma muscles and upper trapezius muscles in the rest and different exercise states.The difference of root-mean-square values between the affected side and the healthy side muscle groups at rest and under different exercise states and the diagnostic value were compared.Spearman correlation analysis was used to evaluate the relationship between the severity of congenital muscular torticollis on the affected side and the root mean square value of each cervical muscle group.Results The root-mean-square value of sternocleidomastoid muscle on the affected side of CMT children was higher than that on the healthy side during relaxation and lower than that on the healthy side during contraction,and the differences were statistically significant(P<0.05),the abnormal root-mean-square value of the affected side in the resting position and in all motion state has higher diagnostic value.The root-mean-square value of platysma muscle on the affected side was higher than that on the healthy side when it was in the resting position and the reverse neck rotation relaxed state(P<0.05),and lower than that on the healthy side when it was in the same neck rotation contraction state(P<0.05),abnormal values detected in resting sitting position and elevation of head have higher value.Root-mean-square value of upper trapezius muscle on the affected side was higher than that on the healthy side in the relaxed state(P<0.05).The abnormal values in sitting position,turning neck and bending head have high diagnostic value.The severity of CMT was positively correlated with the root-mean-square values of sternocleidomastoid muscle,platysma muscle,and upper trapezius muscle(r was 0.721,0.612,0.655,P<0.001).Conclusion sEMG could be used as a good method for the clinical diagnosis and evaluation of congenital muscular torticollis in children.

Data Mining and Systems Pharmacology to Elucidate Effectiveness and Mechanisms of Chinese Medicine in Treating Primary Liver Cancer / 中国结合医学杂志

OBJECTIVE@#To identify specific Chinese medicines (CM) that may benefit patients with primary liver cancer (PLC), and to explore the mechanism of action of these medicines.@*METHODS@#In this retrospective, singlecenter study, prescription information from PLC patients was used in combination with Traditional Chinese Medicine Inheritance Supports System to identify the specific core drugs. A system pharmacology approach was employed to explore the mechanism of action of these medicines.@*RESULTS@#Taking CM more than 6 months was significantly associated with improved survival outcomes. In total, 77 putative targets and 116 bioactive ingredients of the core drugs were identified and included in the analysis (P<0.05). A total of 1,036 gene ontology terms were found to be enriched in PLC. A total of 75 pathways identified from Kyoto Encyclopedia of Genes and Genomes were also enriched in this disease, including fluid shear stress, interleukin-17 signaling, signaling between advanced glycan end products and their receptors, cellular senescence, tumor necrosis factor signaling, p53 signaling, cell cycle signaling, steroid hormone biosynthesis, T-helper 17 cell differentiation, and metabolism of xenobiotics by cytochrome. Docking studies suggested that the ingredients in the core drugs exert therapeutic effects in PLC by modulating c-Jun and interleukin-6.@*CONCLUSIONS@#Receiving CM for 6 months or more improves survival for the patients with PLC. The core drugs that really benefit for PLC patients likely regulates the tumor microenvironment and tumor itself.

Consideration on implementation of co-administration of Seasonal Influenza and COVID-19 vaccines during pandemic in China / 中华预防医学杂志

Influenza is an infectious respiratory disease caused by the influenza viruses. Older people, infants and people with underlying medical conditions could have a higher risk of severe influenza symptoms and complications. The co-infection of Coronavirus Diseases 2019 (COVID-19) with influenza viruses could lead to the complication of prevention, diagnosis, control, treatment, and recovery of COVID-19. Influenza vaccine and COVID-19 vaccine overlapped in target populations, vaccination time, and inoculation units. Although there was insufficient evidence on the immunogenicity and safety of co-administration of influenza vaccine and COVID-19 vaccine, World Health Organization and some countries recommended co-administration of inactivated influenza vaccine and COVID-19 vaccine. This review summarized domestic and international vaccination policies and research progress, and put forward corresponding suggestions in order to provide scientific support for the formulation of vaccination strategy on seasonal influenza vaccine and COVID-19 vaccine.

Textual Research on Trionycis Carapax / 中国实验方剂学杂志

Trionycis Carapax is a commonly used Chinese medicine in clinical practice. Modern research on Trionycis Carapax mainly focuses on experimental research and clinical observation， which has been rarely reported in the literature. Based on the literature on medicinal herbs， medical books， prescriptions of all dynasties， this study carried out systematic textual research on the historical evolution and changes of the name， origin， producing areas， quality， efficacy， indications， processing methods， and contraindications of the Trionycis Carapax. As revealed by the textual analysis， the origin of Trionycis Carapax is Trionyx sinensis， and the carapace of T. steindachneri is not suitable for the preparation of Trionycis Carapax. The genuine producing areas of Trionycis Carapax include Yueyang， Jingzhou， southeast Anhui， and western Jiangsu in the middle and lower reaches of the Yangtze river. Regarding the quality， the number of ribs of Trionycis Carapax， such as seven ribs and nine ribs， is often used as the quality evaluation standard in ancient Chinese herbal books. However， through literature research and field inspections on the medicinal material markets， it is not advisable to take rib number as a quality evaluation criterion in modern times. With the change of the times， the efficacy and indications of Trionycis Carapax have gradually expanded on the basis of Shennong’s Classic of Materia Medica （Shen Nong Ben Cao Jing）， and later generations widely apply it in internal medicine， surgery， gynecology， pediatrics， etc. It should be noted that the treatment of labor heat and bone steaming by Trionycis Carapax is derived from Shennong’s Classic of Materia Medica， not Treatise on the Nature of Medicinal Herbs （Yao Xing Lun） mentioned in ancient books such as Amplification on Materia Medica （Ben Cao Yan Yi）. The processing methods of Trionycis Carapax are diverse， which are dominated by traditional vinegar processing. In terms of contraindications， Trionycis Carapax should not be compatible with bauxite and marble and is contraindicated in pregnant women. Those with spleen deficiency， weak stomach， and liver deficiency without heat should use it with caution. This study is expected to provide the basis for radical reform and further development and clinical utilization of Trionycis Carapax.

Research progress of anesthesia methods in prostate biopsy / 中华外科杂志

Prostate biopsy is the gold standard for the diagnosis of prostate cancer. In order to successfully and effectively complete the biopsy, clinicians should not only select the correct puncture method, but also pay attention to the pain control of patients undergoing puncture. It is necessary to select a reasonable anesthetic method for biopsy. The pain during biopsy comes from the skin, muscle and other structures in the puncture approach, and also comes from the prostate capsule. Therefore, the anesthesia emphasis of transperineal and transrectal biopsy approaches will also be different. The use of appropriate anesthesia is of great significance to improve the patient's cooperation and ensure the success rate of biopsy. With the continuous maturity of the technology and concept of prostate biopsy, a single anesthesia method has been unable to meet the actual anesthetic needs of biopsy, and the use of multi-site and multi-phase combined anesthesia for different sources of pain has become the mainstream anesthetic option.

@#AIM: To investigate the efficacy of anti-inflammatory treatment and anti-vascular endothelial growth factor(VEGF)treatment on different types of macular edema secondary to retinal vein occlusion(RVO-ME).<p>METHODS: The clinical data of RVO-ME patients who were treated in the Department of Ophthalmology, the First Affiliated Hospital of Zhengzhou University from 2019-06/2020-12 were retrospectively collected. A total of 108 cases(108 eyes)of RVO-ME patients were collected, including 52 cases(52 eyes)with cystoid macular edema(CME), 38 cases(38 eyes)with macular edema with serous retinal detachment(SRD), and 18 cases(18 eyes)with diffuse retinal thickening(DRT). Patients with various types of ME were further classified into anti-VEGF group and anti-inflammatory group. The observation metrics such as best corrected visual acuity(BCVA)and foveal thickness(CMT)before and 3mo after surgery were collected and compared in each group.<p>RESULTS: There was no difference in baseline data between the anti-VEGF group and the anti-inflammatory group in all types of ME patients(all P>0.05). Patients with CME in the anti-VEGF group in BCVA, CMT, and the sum of CME diameter after operation were different from that before operation(Z= -4.463, -4.541, -4.541, all P<0.001); the postoperative BCVA, CMT, and the sum of CME diameter in the anti-inflammatory group were significantly different from those before operation(Z= -3.743, -4.345, -4.372, all P<0.001); and there was no difference between the anti-VEGF group and the anti-inflammatory group in the postoperative CMT and the sum of CME diameter(Z= -1.017, -0.968, all P>0.05), but there was a difference in BCVA after operation in two groups(Z= -1.978, P<0.05). SRD patients in the anti-VEGF group had differences in postoperative BCVA, CMT, and SRD heights compared with preoperative ones(Z= -4.111, -4.198, -4.198, all P<0.01); the BCVA, CMT, and SRD height in the anti-inflammatory group after operation were different from those before operation(Z= -3.410, -3.408, -3.408, all P<0.05); and there was no difference in BCVA and CMT between the two groups after operation(Z= -0.857, -1.030, all P>0.05), but the postoperative SRD height in the anti-inflammatory group was significantly lower than that in the anti-VEGF group(Z= -2.117, P<0.05). DRT patients in the anti-VEGF group were significantly different in BCVA and CMT after operation compared with preoperative ones(Z= -2.207, -2.521, all P<0.05), and in the anti-inflammatory group after injection, BCVA and CMT were significantly different from preoperative ones(Z= -2.207, -2.521, all P<0.05). There were differences in BCVA and CMT after injection in the anti-inflammatory group compared with those before operation(Z= -2.207, -2.803, all P<0.05). There was no difference in postoperative BCVA and CMT between the two groups(Z= -0.359, -0.845, all P>0.05). <p>CONCLUSION: Anti-inflammatory and anti-VEGF treatments are effective for all kinds of ME in improving vision and reducing CMT. Anti-VEGF treatment is superior to anti-inflammatory treatment in improving BCVA of CME patients and is inferior to anti-inflammatory in decreasing SRD thickness of SRD patients.

Preliminary study on differentially expressed proteins in a mouse model of secondary cystic echinococcosis based on data independent acquisition proteomics / 中国血吸虫病防治杂志

Objective To identify the differentially expressed proteins in different liver tissues in the mouse model of cystic echinococcosis (CE), so as to provide insights into the research and development of therapeutic drugs targeting CE. Methods Female Kunming mice at ages of 6 to 8 weeks were randomly assigned into the CE group and the control group. Mice in the CE group were intraperitoneally infected with 2 000 Echinococcus multilocularis protoscoleces, while mice in the control group were injected with the same volume of physiological saline. All mice in both groups were sacrificed after breeding for 350 d, and the lesions (the lesion group) and peri-lesion specimens (the peri-lesion group) were sampled from the liver of mice in the CE group and the normal liver specimens (the normal group) were sampled from mice in the control group for data independent acquisition (DIA) proteomics analysis, and the differentially expressed proteins were subjected to Gene Ontology (GO) term enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Results A total of 26 differentially expressed proteins were identified between the lesion group and the normal group and between the peri-lesion group and the normal group, including 8 up-regulated proteins and 18 down-regulated proteins. GO term enrichment analysis showed that these differentially expressed proteins were predominantly enriched in endoplasmic reticulum membrane (biological components), oxidoreductase activity (molecular function) and oxoacid metabolic process and monocarboxylic acid metabolic process (biological processes). KEGG pathway enrichment analysis revealed that the differentially expressed protein Acyl-CoA oxidase 1 (Acox1), which contributed to primary bile acid biosynthesis during the fatty acid oxidation, was involved in peroxisome signaling pathway, and the differentially expressed protein fatty acid binding protein 1 (Fabp1), which contributed to fatty acid transport, was involved in the peroxisome proliferator-activated receptor (PPAR) signaling pathway. Conclusion Differentially expressed proteins are identified in the liver specimens between mouse models of CE and normal mice, and some differentially expressed proteins may serve as potential drug targets for CE.

Preliminary study on differentially expressed proteins in a mouse model of secondary alveolar echinococcosis based on data independent acquisition proteomics / 中国血吸虫病防治杂志

Objective To identify the differentially expressed proteins in different liver tissues in the mouse model of alveolar echinococcosis using high-resolution mass spectrometry with data independent acquisition (DIA), and to identify the key proteins contributing to the pathogenesis of alveolar echinococcosis. Methods Protoscoleces were isolated from Microtus fuscus with alveolar echinococcosis and the experimental model of alveolar echinococcosis was established in female Kunming mice aged 6 to 8 weeks by infection with Echinococcus multilocularis protoscoleces. Mice were divided into the experimental and control groups, and animals in the experimental group was injected with approximately 3 000 protoscoleces, while mice in the control group were injected with the same volume of physiological saline. Mouse liver specimens were sampled from both groups one year post-infection and subjected to pathological examinations. In addition, the lesions (the lesion group) and peri-lesion specimens (the peri-lesion group) were sampled from the liver of mice in the experimental group and the normal liver specimens (the normal group) were sampled from mice in the control group for DIA proteomics analysis, and the differentially expressed proteins were subjected to bioinformatics analysis. Results A total of 1 020 differentially expressed proteins were identified between the lesion group and the normal group, including 671 up-regulated proteins and 349 down-regulated proteins, and 495 differentially expressed proteins were identified between the peri-lesion group and the normal group, including 327 up-regulated proteins and 168 down-regulated proteins. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis revealed that these differentially expressed proteins were involved in peroxisome, peroxisome proliferator-activated receptor (PPAR) and fatty acid degradation pathways, and the peroxisome and PPAR signaling pathways were found to correlate with liver injury. Several differentially expressed proteins that may contribute to the pathogenesis of alveolar echinococcosis were identified in these two pathways, including fatty acid binding protein 1 (Fabp1), Acyl-CoA synthetase long chain family member 1 (Acsl1), Acyl-CoA oxidase 1 (Acox1), Enoyl-CoA hydratase and 3-hydroxyacyl CoA dehydrogenase (Ehhadh) and Acetyl-Coenzyme A acyltransferase 1B (Acaa1b), which were down-regulated in mice in the experimental group. Conclusion A large number of differentially expressed proteins are identified in the liver of the mouse model of alveolar echinococcosis, and Fabp1, Acsl1, Acox1, Ehhadh and Acaa1b may contribute to the pathogenesis of alveolar echinococcosis.

Analysis on Role of mTORC1/4E-BP1 Axis in Idiopathic Pulmonary Fibrosis and Research Progress of Bupleuri Radix on Its Intervention / 中国实验方剂学杂志

Idiopathic pulmonary fibrosis （IPF） is a common， lethal interstitial lung disease characterized by airway remodeling， inflammation， alveolar destruction， and fibrosis. The mammalian target of rapamycin complex 1/4E binding protein 1 （mTORC1/4E-BP1） axis is closely related to the expression of collagen by fibroblasts， and its role in pulmonary fibrosis remains to be further elucidated. Traditional Chinese medicine （TCM） has shown promising efficacy in improving the lung function， exercise capacity， and quality of life in patients with IPF. The theory of "same treatment for different diseases" provides a TCM theoretical basis for the treatment of pulmonary fibrosis with Bupleuri Radix， while the research in western medicine has preliminarily shown that both the formulation and single herb as well as the active ingredients of Bupleuri Radix have good therapeutic effects on pulmonary fibrosis. Therefore， this review will elaborate on the role of the mTORC1/4E-BP1 axis in the pathomechanism of IPF， as well as the research results of the active components of Bupleuri Radix on the phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin protein（PI3K/AKT/mTOR） pathway， so as to provide a reference for the treatment and drug development of IPF.
