ABSTRACT
AIM:To investigate the inhibitory effect of the"decoction for soothing liver and removing stasis and toxicity(SGQYJDF)"on hepatocellular carcinoma(HCC)proliferation in nude mice by inducing ferroptosis via the tumor protein 53(p53)/solute carrier family 7 member 11(SLC7A11/xCT)/glutathione peroxidase 4(GPX4)pathway.METHODS:An ectopic subcutaneous tumor model was established by injecting SK-Hep-1 cells subcutaneously into the right axilla of nude mice.Upon formation of tumor,the mice were randomly divided into five groups(i.e.,control group,low-,medium-and high-dose SGQYJDF groups and medium-dose SGQYJDF plus Sorafenib group).Each group of mice was orally administered with the corresponding therapy for 14 consecutive days,during which the tumor size was observed regularly.At the end of treatment,the tumor growth inhibition rate was calculated based on tumor mass,and histopatho-logical changes were observed by HE staining.Then,the levels of malondialdehyde(MDA),glutathione(GSH)and fer-rous ions(Fe2+)were detected by colorimetric assays.The expression of the proliferation markers Ki-67 and GPX4 was de-tected by immunohistochemistry(IHC).The expression of p53 and xCT was detected by Immunofluorescence(IF).And the expression of p53,xCT and GPX4 was determined by Western blot.RESULTS:(1)SGQYJDF was found to dose-de-pendently decrease tumor volume(P<0.01)and inhibit tumor mass growth(P<0.01),and meanwhile,reduce the per-centage of Ki-67-positive cells(P<0.01)and their proliferation ability in tumor tissues,as compared to the control group.(2)In terms of Ferroptosis-related indicators,SGQYJDF was found to dose-dependently increase the levels of Fe2+ and MDA but decrease the level of GSH in tumor tissues(P<0.01),as compared to the control group.(3)In terms of protein expression,SGQYJDF was found to dose-dependently upregulate the expression of p53(P<0.05)but inhibit the expres-sion of xCT(P<0.05)and GPX4(P<0.01).Notably,medium-dose SGQYJDF plus sorafenib showed a stronger effect than high-dose SGQYJDF.CONCLUSION:Our findings suggest that SGQYJDF can induce Ferroptosis to inhibit the proliferation of subcutaneously transplanted tumor tissues in nude mice by upregulating the expression of p53,and inhibit-ing the expression of xCT and GPX4.

Conclusions:Zhushui plaster application and nursing combined with elemene injection can not only effectively control the negative psychological state of lung cancer patients with malignant pleural effusion and reduce the degree of cancer-related fatigue, but also improve their quality of life.
ABSTRACT
Cholestatic liver diseases (CLD) are a series of diseases due to impaired bile flow and accumulation of bile acid in the liver and/or systemic circulation caused by immune, genetic, and environmental factors. The pathogenesis of CLD remains unclear and CLD is difficult to treat. As a substitute for human diseases, animal models can provide a platform for exploring the etiology and pathogenesis of the disease and finding appropriate therapeutic targets. This article reviews the current research advances in the animal models of CLD.
ABSTRACT
{L-End}Objective To analyze the local muscle response under continuous ergonomic workload by simulating manual lifting, and to screen the sensitive metabolic biomarkers during fatigue process. {L-End}Methods A total of 13 healthy male volunteers were selected as the study subjects using simple random sampling method. Study subjects underwent repetitive simulated manual lifting for four periods (T1 to T4), each lasting 12 minutes. The degree of work-related fatigue in the forearm, upper arm, shoulder, back, and leg muscles, and the whole body was accessed using Borg 6-20 Rating of Perceived Exertion (RPE) Scale. The venous blood samples were collected from elbow between each two periods to detect the levels of eight metabolic biomarkers: ammonia, lactate, creatine kinase, lactate dehydrogenase (LDH), C-terminal telopeptide of type Ⅰ collagen (CTX-Ⅰ), C-terminal telopeptide of type Ⅱ collagen (CTX-Ⅱ), cartilage oligomeric matrix protein (COMP), and calcium ions. {L-End}Results The RPE scores of the study subjects for the muscles of five body parts and the whole body increased with the increasing lifting periods (all P<0.01). Fatigue was observed in all target muscles, with overall body fatigue occurring in the T2 period. The levels of ammonia, lactate, creatine kinase, LDH, COMP, and calcium ions in the serum of study subjects were higher in the T1 to T4 periods than in the T0 period (all P<0.05). The serum CTX-Ⅰ level was higher in the T1 and T3 periods than that in the T0 period (all P<0.05) , and the serum CTX-Ⅱ level was higher in the T1, T2 and T4 periods than that in the T0 period (all P<0.05). The level of these eight serum metabolic biomarkers fluctuated during the T1 to T4 periods. The serum creatine kinase level increased with the period of lifting (all P<0.05). The serum lactate level was higher in the T3 period than those in the T1 and T2 periods (all P<0.05). The serum LDH and calcium ion levels were higher in the T2 to T4 periods than that in the T1 period (all P<0.05). The serum COMP level was higher in the T2 and T3 periods than that in the T1 period (all P<0.05). Except for CTX-Ⅰ, the levels of other seven metabolic markers in serum were higher in individuals after fatigue than before fatigue (all P<0.05). {L-End}Conclusion Serum metabolic biomarkers such as ammonia, lactate, creatine kinase, calcium ions, LDH, CTX-Ⅱ, and COMP exhibit significant changes before and after fatigue. These metabolic biomarkers could be used as sensitive biomarkers for evaluating muscle fatigue during repetitive works.

ABSTRACT
OBJECTIVE@#To observe the occurrence time of neuralgia and the expression of purinergic ligand-gated ion channel 7 receptor (P2X7R) in the dorsal horn of the spinal cord after intraperitoneal injection of streptozotocin (STZ) in diabetic rats, and to explore the effect of electroacupuncture (EA) and pretreatment of EA on the heat pain threshold and expression of P2X7R in the spinal dorsal horn in rats with diabetic neuropathic pain (DNP), and to explore the possible mechanism of EA for DNP.@*METHODS@#PartⅠ: Thirty male SD rats were randomly selected from 64 male SD rats as the control group; the remaining rats were given intraperitoneal injection of STZ (10 mg/mL) at a dose of 65 mg/kg to establish the diabetes model, and 30 rats were successfully modeled as the model group. The control group and the model group were divided into three subgroups respectively at 7, 14 and 21 days, with 10 rats in each subgroup. Body mass, fasting blood glucose (FBG) and thermal pain threshold were recorded at 7, 14 and 21 days after injection; the expression of P2X7R in spinal dorsal horn was detected by Western blot. PartⅡ: Eight SD rats were randomly selected from 35 male SD rats as the blank group, and the remaining 27 rats were given intraperitoneal injection of STZ (10 mg/mL) at a dose of 65 mg/kg to establish the diabetes model. The 24 rats with successful diabetes model were randomly divided into a DNP group, an EA group and a pre-EA group, 8 rats in each group. Fifteen to 21 days after STZ injection, the EA group received EA at "Zusanli" (ST 36) and "Kunlun" (BL 60), continuous wave, frequency of 2 Hz, 30 min each time, once a day; the intervention method in the pre-EA group was the same as that in the EA group. The intervention time was 8 to 14 days after STZ injection. The body mass, FBG and thermal pain threshold were recorded before STZ injection and 7, 14 and 21 days after STZ injection; the expression of P2X7R in spinal dorsal horn was detected by Western blot 21 days after injection.@*RESULTS@#PartⅠ: Compared with the control group, in the model group, the body mass was decreased and FBG was increased 7, 14 and 21 days after STZ injection (P<0.01), and the thermal pain threshold was decreased 14 and 21 days after STZ injection (P<0.05), and the expression of P2X7R in spinal dorsal horn was increased 7, 14 and 21 days after STZ injection (P<0.05, P<0.01). PartⅡ: Compared with the blank group, in the DNP group, the body mass was decreased and fasting blood glucose were increased 7, 14 and 21 days after STZ injection (P<0.01). Compared with the DNP group, in the pre-EA group, the heat pain threshold was increased 14 and 21 days after STZ injection (P<0.05), while in the EA group, the heat pain threshold was increased 21 days after STZ injection (P<0.01), and the expression of P2X7R in the dorsal horn in the EA group and the pre-EA group was decreased (P<0.01).@*CONCLUSION@#The diabetic neuropathic pain is observed 14 days after STZ injection. EA could not only treat but also prevent the occurrence of DNP, and its mechanism may be related to down-regulation of P2X7R expression in the dorsal horn of the spinal cord.

OBJECTIVE: To explore the influencing factors of low back pain and the relationship of the influence of bad working posture, weight load and frequency of load and the dose-response relationship among the occupational workers of key industries in China. METHODS: A total of 57 501 employees from 15 key industries in China were selected as research subjects using stratified cluster sampling method. The occurrence of low back pain in the past one year, as well as occupational factors such as job type, labor organization and work posture were investigated by using the Chinese version Musculoskeletal Disorders Questionnaire. RESULTS: The prevalence of low back pain in the occupational population of key industries in China was 16.4%(9 448/57 501). Multivariate Logistic regression analysis showed that the risk of low back pain in females was higher than that in males(P<0.01). Married, obese, occasional and frequent smokers, and a history of lower back disease were associated with increased risk of low back pain(all P<0.05). The risk of low back pain was associated with older age, higher education level, and lower frequency of physical exercise(all P<0.01). The risk of low back pain was higher with longer working time, greater back curvature, and the high frequency of long standing and sitting position work, uncomfortable working posture, repeated operation per minute, and lifting>5 kg weight(all P<0.01). CONCLUSION: The influencing factors of low back pain in the occupational population of key industries in China include bad working posture, high frequency load, weight load and other individual factors. There is a dose-response relationship with low back posture load and frequency of load.
ABSTRACT
OBJECTIVE: To explore the association of serum Apelin level, silicosis stage and lung function in patients with occupational silicosis(hereinafter referred to as silicosis). METHODS: A case-control study was conducted. A total of 85 patients with silicosis were selected as the silicosis group(44, 28 and 13 patients with stage Ⅰ, Ⅱ and Ⅲ silicosis, respectively), and 120 healthy individuals without occupational hazard exposure were selected as the control group. Serum samples were collected from the cases of the two groups and the level of Apelin was determined by enzyme-linked immunosorbent assay. The pulmonary function of the silicosis group was examined. RESULTS: The median and the 25 th and 75 th percentiles \[M(P_(25),P_(75))\] of serum Apelin levels in the control group and silicosis group were 1.29(0.92, 1.77) and 0.80(0.62, 1.04) mg/L, respectively. The level of serum Apelin M(P_(25),P_(75)) in stage Ⅰ, Ⅱ and Ⅲ silicosis patients was 1.03(0.82, 1.31), 0.66(0.60, 0.80) and 0.50(0.30, 0.65) mg/L, respectively. The results of multiple linear regression analysis showed that the level of serum Apelin in the silicosis group was higher than that in the control group after excluding the influence of age and smoking(P<0.01). The level of serum Apelin decreased with the increase of silicosis stage in the silicosis group(P<0.001). Serum Apelin level in silicosis group was positively correlated with lung vital capacity, forced vital capacity, forced expiratory volume in the first second, and forced expiratory flow between 25% and 75%(all P<0.05). CONCLUSION: The lower level of serum Apein in silicosis patients, the more serious the disease and the more serious the damage to lung function. Apelin is of significance in the diagnosis, staging, treatment appraisal and prognostic evaluation of silicosis, and it can be use as a potential therapeutic target for silicosis.

ABSTRACT
OBJECTIVE: To assess the effect of ergonomic factor load on work-related musculoskeletal disorders(WMSDs) in shipyard workers. METHODS: A total of 751 shipyard workers were selected as the research subjects using judgment sampling method. The exposure level of adverse ergonomic factors was assessed using the Quick Exposure Check method. The prevalence of WMSDs was investigated using the revised Musculoskeletal Disorders Investigating Questionnaire of our research group, and the relationship between them was analyzed. RESULTS: The proportions of high or very high level of work load exposure to the neck, back, shoulder and hand in shipyard workers from high to low were 66.4%, 63.5%, 59.8% and 43.7%(P<0.01) respectively. The proportions of occupational stress, driving, vibration and working rhythm at high or very high exposure level were 20.0%, 4.1%, 22.9% and 3.2%, respectively. The prevalence of WMSDs in four body parts of shipyard workers from high to low was the back, neck, hand and shoulder(the prevalence were 44.2%, 31.2%, 26.9% and 26.6%, respectively, P<0.01). After excluding the influence of confounding factors, multiple logistic regression analysis showed that the higher the labor load exposure level and longer of the vibration tool using, the higher the risk of shoulder WMSDs [odds ratio(OR) and 95% confidence interval(CI) were 1.25(1.04-1.51) and 1.33(1.05-1.69), respectively, P<0.05]. The higher the level of occupational stress, the higher the risk of back and neck WMSDs [OR(95%CI) was 1.29(1.05-1.58) and 1.42(1.15-1.77), respectively, P<0.05]. CONCLUSION: There was a dose-effect relationship between the exposure level of shoulder load, the time of using vibration tools and the shoulder WMSDs, and there was a dose-effect relationship between the occupational stress level and the WMSDs in the back and neck.
ABSTRACT
The aim of this paper was to investigate the effect of Schizonepetae Herba and Saposhnikoviae Radix(wind medicine) on the expression of AQP4 and AQP8 in colonic mucosa in rats with ulcerative colitis(UC). A total of 35 healthy SD male rats were randomly divided into normal group(gavaged with normal saline), DSS model group, as well as low, middle, and high dose wind medicine groups(Schizonepeta and Saposhnikovia 1∶1, gavaged at dosages of 6, 12, and 24 g·kg~(-1)·d~(-1)), with 7 in each group. UC rat model was established by free drinking of 3% dextran sulphate sodium(DSS) solution for 10 days. At the end of the 10 th day after the treatment, mice were put to death to collect colonic mucosa. The length of colon was measured; the colonic mucosal injury index(CMDI) and pathological changes of colon were observed. ELISA method was used for measuring the content of serum IL-1, IL-8, and immunohistochemical method was used to measure AQP4, AQP8 protein expressions in colon mucosa. The expressions of AQP4, AQP8 mRNA were measured by Real-time PCR. As compared with the normal group, the length of colon tissue was significantly reduced(P<0.01), CMDI scores and pathological scores were significantly increased(P<0.01), the levels of serum IL-1 and IL-8 were significantly increased(P<0.05) in model group; the immunohistochemical results showed that the protein expressions of AQP4, AQP8 were lower; the color was light yellow or brown; AQP4, AQP8 mRNA expressions in colon mucosa were significantly decreased in model group(P<0.01). CMDI scores, pathological scores, and the levels of serum IL-1, IL-8 in high, middle, low dose wind medicine groups were obvious lower than those in the model group(P<0.01 or P<0.05); the protein expressions of AQP4, AQP8 were higher; the color was chocolate brown or dark brown; the length of colon tissue, and the expressions of AQP4, AQP8 mRNA were obvious higher in wind medicine groups(P<0.01 or P<0.05). Schizonepetae Herba and Saposhnikoviae Radix could significantly improve the symptoms and histopathology of UC model rats and accelerate the intestinal mucosal healing. The mechanism may be related with up-regulating the expression level of AQP4 and AQP8 in colonic mucosa.

ABSTRACT
Myasthenia gravis (MG) is a prototypical antibody-mediated neurological autoimmune disease with the involvement of humoral immune responses in its pathogenesis. T follicular helper (Tfh) cells have been implicated in many autoimmune diseases. However, whether and how Tfh cells are involved in MG remain unclear. Here, we established and studied a widely-used and approved animal model of human MG, the rat model with acetylcholine receptor alpha (AChRα) subunit (R-AChR)-induced experimental autoimmune myasthenia gravis (EAMG). This model presented mild body-weight loss 10 days after the first immunization (representing the early stage of disease) and more obvious clinical manifestations and body-weight loss 7 days after the second immunization (representing the late stage of disease). AChR-specific pre-Tfh cells and mature Tfh cells were detected in these two stages, respectively. In co-cultures of Tfh cells and B cells, the number of IgG2b-secreting B cells and the level of anti-AChR antibodies in the supernatant were higher in the cultures containing EAMG-derived Tfh cells. In immunohistochemistry and immunofluorescence assays, a substantial number of CD4/Bcl-6 T cells and a greater number of larger germinal centers were observed in lymph node tissues resected from EAMG rats. Based on these results, we hypothesize that an AChR-specific Tfh cell-mediated humoral immune response contributes to the development of EAMG.

OBJECTIVE: To analyze the relationship between the blood biochemical indexes and the local muscle fatigue of operators with local muscle fatigue caused by moderate-load repetitive manual lifting. METHODS: Five healthy male volunteers were selected as the research subjects. They repeatedly performed simulated manual lifting operation for four periods(T1-T4), 10 minutes per period. Each period was suspended for 3 minutes to be accessed for the rating of perceived exertion(RPE) score of local muscle. Meanwhile, their venous blood was collected to be detected for serum calcium ion, creatine kinase, cartilage oligomeric matrix protein(COMP), ammonia, lactic acid, lactate dehydrogenase(LDH), C-reactive protein(CRP), and collagen type Ⅱ C terminal telopeptide(CTX-Ⅱ). RESULTS: The RPE score and serum creatine kinase level of the subjects increased with the increasing of lifting time(P<0.05). Serum calcium ion levels in time periods T2, T3 and T4 were higher than that in T1(P<0.05). Serum COMP levels in T3 and T4 were higher than that in T1(P<0.05). The levels of ammonia,lactic acid, LDH, CRP and CTX-Ⅱ in each time period showed no statistical significance(P>0.05). Serum creatine kinase, calcium ion and LDH levels were positively correlated with RPE score(correlation coefficient were 0.840, 0.512, 0.741, respectively, P<0.01). CONCLUSION: Serum creatine kinase is a sensitive, effective and objective index reflecting muscle fatigue, which is suitable for evaluating the fatigue process of moderate-load repetitive activities. Serum calcium ion has a good correlation with muscle fatigue, and serum COMP can reflect muscle fatigue to some extent.
ABSTRACT
The aim of this paper was to screen the active targets of Schizonepetae Herba and Saposhnikoviae Radix in the treatment of ulcerative colitis by means of network pharmacology,and to investigate their mechanism of action. The effective components of Schizonepetae Herba and Saposhnikoviae Radix were screened out by traditional Chinese medicine systematic pharmacological( TCMSP)database,with oral bioavilability( OB) ≥30% and drug-like( DL) ≥18% selected as the thresholds. Target PPI network was built between the main components and their corresponding targets. One hundred and eighty-two human genes corresponding to the medicine target sites were obtained from Uniprot database; 3 874 genes corresponding to ulcerative colitis were obtained from Genecard database.A total of 115 intersection genes were screened from disease genes and medicine genes,and the PPI interaction analysis was conducted by using String tool. Disease-target PPI network was drawn by using Cytoscape software,and component-target-disease network was constructed. One hundred and eight nodes and 1 882 connections were found,and then Cytoscape software was used to merge the networks and filter the core network for gene GO function analysis and KEGG pathway enrichment analysis. The mechanism of Schizonepetae Herba and Saposhnikoviae Radix was then verified by animal experiment. Gene GO functional analysis suggested that biological process,molecular functions and cell components were involved,and it was found that ulcerative colitis might be related to transcription factor activity,and cytokine receptor binding,etc. Gene KEGG pathway enrichment analysis showed that the mechanism of ulcerative colitis might be associated with TNF and Toll-like receptors( TLRs) signaling pathway-mediated cytoinflammatory factors interleukin-1( IL-1) and interleukin-6( IL6). The possible mechanism of the effective components of Schizonepetae Herba and Saposhnikoviae Radix in treating ulcerative colitis might be related to intervening the cytokine receptor binding of TNF and TLRs signaling pathways,reducing the transcription of nuclear factor-kappaB( NF-κB),and inhibiting the secretion of intestinal inflammatory factors IL-1 and IL-6.

Objective:To investigate the clinical effect of botulinumtoxin type A (Botox-A) combined with electromyographic biofeedback therapy on the upper limb muscle spasm after stroke.Methods:86 cases of patients with upper limb muscle spasm after stroke in our hospital from January 2016 to January 2017 were selected and divided into the observation group and the control group,with 43 cases in each group.Patients in the control group were treated with electromyographic biofeedback therapy,and the observation group was treated with Botox-A based on the basis of control group.The improvement of upper limb muscle spasm,Upper limb movement function,the active range of wrist joint and life skills before and after treatment were compared between two groups.Results:After treatment,the total effective rate of improvement of upper limb muscle spasm of observation group were significantly higher than that of the control group (P<0.05);At 2 weeks and 4 weeks after treatment,the Fugl-Meyer scores,Wrist joint activities,modified Barthel index (MBI) of two groups were significantly higher than those before treatment (P<0.05),which were significantly higher in the observation group than those of the control group (P<0.05).Conclusion:Botox-Acombined with electromyographic biofeedback therapy had remarkable clinical effect on the upper limb muscle spasm after stroke,which could effectively reduce the upper limb spasticity,improve the arm and wrist movement ability and the ability of daily life.
ABSTRACT
Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease, and the spectrum of this disease includes simple liver steatosis, nonalcoholic steatohepatitis, liver fibrosis, and liver cirrhosis. At present, liver biopsy is still the gold standard for the diagnosis of NAFLD and can determine the degree of steatosis, inflammation grade, and fibrosis stage, but its clinical application is limited by its invasiveness and static nature. New diagnostic markers and noninvasive diagnostic methods have been reportedly recently, and the constant development of magnetic resonance imaging, transient elastography, and controlled attenuation parameter provides new methods for the noninvasive diagnosis of NAFLD.
