ABSTRACT

Inflammatory bowel disease (IBD) is a heterogeneous group of disorders characterized by the chronic refractory inflammation of gastrointestinal tract. Although the pathogenesis of IBD has not been fully elucidated, there is increasing evidence that various environmental factors, including dietary nutrition, play an important role in the occurrence and development of the disease. Dietary nutrition has the effect on modulating the gut microbiome and regulating immune system, and even shows potential influence on epigenetic regulations. Therefore, diet has raised great research interest as a therapeutic tool to improve the disease course, due to its fewer side effects. Here is a review of the role of dietary nutrients in the development and treatment of IBD, with emphasis on fiber, fat, vitamin D, zinc, selenium and three specific dietary patterns considered applicable to the management of IBD therapy, namely the special carbohydrate diet, the low fermentable oligosaccharides, disaccharides, monosaccharides and polyol diet, and the Mediterranean diet.

ABSTRACT

Due to the limited resource of bear bile powder, the major raw material of Tanreqing Capsules(TRQ), cultured bear bile powder is used as a replacement to develop the Tanreqing Capsules Substitute(TRQS). An LC-MS/MS method was established in this study for simultaneous quantitation of 8 compounds from TRQS in rat plasma: tauroursodeoxycholic acid(TUDCA), taurocheno-deoxycholic acid(TCDCA), ursodeoxycholic acid(UDCA), chenodeoxycholic acid(CDCA), ferulic acid, wogonoside, baicalin, and forsythoside A. Thereby, the pharmacokinetic behaviors of TRQ and TRQS were evaluated. Concentration of endogenous compounds TUDCA, TCDCA, UDCA, and CDCA was determined with the stable isotope surrogate analytes: D4-TUDCA, D4-TCDCA, D4-UDCA, and D4-CDCA. Plasma samples were extracted by acetonitrile-induced protein precipitation. The LC conditions are as follows: Waters BEH C_(18) column(2.1 mm×100 mm, 1.7 μm), mobile phase of 10 mmol·L~(-1) ammonium formate aqueous solution(containing 0.01% formic acid) and acetonitrile-methanol mixture(1∶5). MS conditions are as below: multiple reaction monitoring(MRM), ESI~(+/-). Concentration of UDCA, CDCA, TUDCA, and TCDCA was corrected with a response factor, which is the ratio between the responses recorded for the surrogate and the authentic analyte at the equal concentration. Each of the plasma components showed good linearity(r > 0.995 1). Accuracy and precision met the criteria(inter-day RSD<7.0%, RE 89.98%-112.0%; intra-day RSD<12%, RE 90.41%-111.2%). The recovery was 64.83%-119.9% and matrix effect was 87.15%-113.8%. The validated method was applied for pharmacokinetic study of TRQS and TRQ(po, 0.94 g·kg~(-1)). There was no significant difference in C_(max) and AUC_(0-24 h) of baicalin, UDCA, TUDCA, and TCDCA between the two groups, indicating similar pharmacokinetic behaviors between TRQS and TRQ in rats.

ABSTRACT

Objective:To study the effect of ulinastatin combined with early enteral nutrition on severe acute pancreatitis and its effect on nuclear factor-κB(NF-κB) and Toll-like receptor 4 (TLR4).Methods:Ninety severe acute pancreatitis patients who were treated in Central Hospital of Lijin County from January 2016 to January 2020 were selected and were divided into U+EEN group (ulinastatin combined with early enteral nutrition therapy) and EEN group (early enteral nutrition therapy) by random number table method, with 45 patients in each group. Curative effect, complications, nutritional indicators, immunoglobulins and inflammatory factors were detected and compared with analysis of variance. Western blot was used to detect the expression of NF-κB and TLR4 in pancreatic tissue in two groups.Results:The hospitalization time, ICU admission time, intestinal ventilation time, hospitalization costs and organ failure rate, pancreatic cysts, diabetes, chronic pancreatitis, incidence of sepsis in U + EEN group were lower than those in EEN group: (2.1 ± 0.4) months vs. (2.4 ± 0.6) months, (16.9 ± 2.1) d vs. (21.7 ± 2.8) d, (23.7 ± 3.8) d vs. (27.4 ± 4.1) d, (11.4 ± 1.5) thousand Yuan vs. (14.1 ± 2.1) thousand Yuan and 8.9%(4/45) vs. 20.0%(9/45), 13.3%(6/45) vs. 28.9%(13/45), 11.1%(5/45) vs. 24.4%(11/45), 8.9%(4/45) vs. 26.7%(12/45), 6.7%(3/45) vs. 22.2%(10/45), and the differences were statistically significant ( P<0.05). The levels of prealbumin (PA), albumin (ALB) and total protein (TP) after treatment in U + EEN group were higher than those in EEN group: (107.4 ± 6.5) mg/L vs. (102.8 ± 4.7) mg/L, (46.1 ± 3.5) g/L vs. (43.4 ± 2.8) g/L, (55.9 ± 3.4) g/L vs. (53.7 ± 3.1) g/L, and the differences were statistically significant ( P<0.05). The levels of IgG, IgA, IgM after treatment in U+EEN group were higher than those in EEN group: (10.5 ± 1.6) g/L vs. (9.5 ± 1.3) g/L, (8.9 ± 1.4) mg/L vs. (8.3 ± 1.2) mg/L, (60.5 ± 3.6) mg/L vs. (55.9 ± 3.4) mg/L, the levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-8 in U+EEN group were lower than those in EEN group: (25.1 ± 2.9) mg/L vs. (30.6 ± 4.1) mg/L, (20.1 ± 1.9) mg/L vs. (24.6 ± 1.5) mg/L, (17.8 ± 1.9) mg/L vs. (20.1 ± 2.3) mg/L, and the differences were statistically significant ( P<0.05). The expressions of NF-κB and TLR4 protein in pancreatic tissue of patients in U + EEN group were significantly lower than those in EEN group (0.3 ± 0.2 vs. 0.5 ± 0.2, 0.2 ± 0.1 vs. 0.5 ± 0.1, P<0.05). Conclusions:Ulinastatin combined with early enteral nutrition can significantly improve the nutritional status and immune function and improve the prognosis of patients with severe acute pancreatitis, which may be related to ulinastatin′s reduction effect of NF-κB and TLR4′s expressions.

ABSTRACT

OBJECTIVE@#To assess the impact of early relapse (ER) after autologous hematopoietic stem cell transplan-tation (AHSCT) on overall survival (OS) for multiple myeloma (MM) patients.@*METHODS@#Clinical data of 37 patients with MM undergoing AHSCT in department of hematology of Shanxi Bethune Hospital from January 2012 to December 2017 were retrospectively analyzed. The effect of ER on OS of patients was analyzed. The effects of international staging system (ISS) staging, cytogenetics, pre-transplant efficacy, minimal residual disease, and age on OS of the patients were also analyzed respectively.@*RESULTS@#Among the 37 patients, 13 cases (35.1%) had ER, and 24 cases (64.9%) had non-ER. 3 patients with ER had extramedullary disease, but none with non-ER showed extramedullary disease. More than or equal to very good partial rate (VGPR) in patients with ER and without ER were 3 cases (23.1%) and 15 cases (62.5%), respectively, and the curative effect of the former was significantly lower than that of the latter (P<0.05). The median follow-up time was 31 (12-96) months, and median OS time was 93 months in all the patients. The median survival time of patients with ER was 17 months, and the median progression free survival was 7 months, both were significantly shorter than 93 months and 38 months of patients with non-ER (P<0.05). Univariate analysis showed that the OS was affected by ER, cytogenetic abnormalities (FISH), and ≥VGPR before transplantation. Multivariate analysis showed that ER was an independent prognostic factor.@*CONCLUSION@#The prognosis of patients with ER after AHSCT in newly diagnosed MM is poor. ER is an independent prognostic factor of survival.

ABSTRACT

Ossifying fibroma (OF) and fibrous dysplasia (FD) are two fibro-osseous lesions with overlapping clinicopathological features, making diagnosis challenging. In this study, we applied a whole-genome shallow sequencing approach to facilitate differential diagnosis via precise profiling of copy number alterations (CNAs) using minute amounts of DNA extracted from morphologically correlated microdissected tissue samples. Freshly frozen tissue specimens from OF (n = 29) and FD (n = 28) patients were obtained for analysis. Lesion fibrous tissues and surrounding normal tissues were obtained by laser capture microdissection (LCM), with ~30-50 cells (5 000-10 000 µm

ABSTRACT

Postprostatectomy erectile dysfunction (pPED) remains a current problem despite improvements in surgical techniques. Vacuum therapy is clinically confirmed as a type of pPED rehabilitation. However, its underlying mechanisms are incompletely understood. Recently, autophagy and apoptosis were extensively studied in erectile dysfunction resulting from diabetes, senescence, and androgen deprivation but not in the context of pPED and vacuum therapy. Therefore, this study was designed to investigate the roles of autophagy and apoptosis in pPED and vacuum therapy. Twenty-four adult male Sprague-Dawley rats were randomly divided into three groups: the control group, bilateral cavernous nerve crush (BCNC) group, and BCNC + vacuum group. After 4 weeks of treatment, intracavernosal pressure was used to evaluate erectile function. Real-time quantitative polymerase chain reaction, western blot, and immunohistochemistry were used to measure the molecular expression. TdT-mediated dUTP nick-end labeling staining was used to assess apoptosis. Transmission electron microscopy was used to observe autophagosomes. After treatment, compared with those of the BCNC group, erectile function and cavernosal hypoxia had statistically significantly improved (P < 0.05). Apoptosis and the relative protein expression of B-cell lymphoma-2-associated X and cleaved Caspase3 were decreased (P < 0.05). Autophagy-related molecules such as phosphorylated unc-51-like autophagy-activating kinase 1 (Ser757) and p62 were decreased. Beclin1, microtubule-associated protein 1 light chain 3 A/B, and autophagosomes were increased (P < 0.05). Besides, the phosphatidylinositol 3-kinase/AKT/mammalian target of rapamycin signaling pathway, as a negative regulator of autophagy to some degree, was inhibited. This study revealed that vacuum therapy ameliorated pPED in BCNC rats by inhibiting apoptosis and activating autophagy.

ABSTRACT

Penile length shortening and erectile dysfunction are common complications after radical prostatectomy. Various methods have been used to maintain erectile function, but less attention has been paid to preserving penis length. N-acetylcysteine (NAC) has the effect of antioxidation and antifibrotic, which may be beneficial to improve those postoperative complications. This study investigated the effect of NAC on maintaining the penile length and the erectile function after bilateral cavernous nerve crush (BCNC) and its underlying mechanism. Twenty-four male rats were randomly divided into three groups: control group, BCNC group, and BCNC + NAC group. NAC or equal volume of saline was daily administrated by intragastric gavage for 4 weeks. The initial and end penile lengths were measured. Intracavernosal pressure/mean arterial pressure (ICP/MAP) ratio was calculated to assess erectile function. Hematoxylin-eosin staining, Masson's trichrome staining, immunohistochemistry, and Western blot were performed to explore cellular and molecular changes of the penis. Compared to the BCNC group, the penile length, ICP/MAP ratio and smooth muscle/collagen ratio in the BCNC + NAC group were improved significantly (all P < 0.05), and the expressions of endothelial nitric oxide synthase, α-smooth muscle actin, glutathione, and glutathione peroxidase 1 were significantly increased after NAC treated (all P < 0.05), along with the decreased expressions of hypoxia-inducible factor-1α, transforming growth factor-β1, collagen I, collagen III, collagen IV, malonaldehyde, and lysine oxidase (all P < 0.05). This study demonstrated that NAC could maintain penile length and partly improve erectile function. Possible mechanism is directly and/or indirectly related to antihypoxic and antifibrosis.

ABSTRACT

Objective:To examine the effect of FAM83D knockdown on proliferation, survival ability and invasion of human esophageal squamous cell carcinoma after X-ray radiation, and explore the mechanism.Methods:The expression of FAM83D, E-cadherin and vimentin in tumor tissues was detected in 69 cases of esophageal squamous cell cancer by using immunohistochemical method. The siRNA based on the sequences of the FAM83D mRNA were synthesized to transfect into the cultured ECA109 cells as FAM83D shRNA group. The effect of silencing FAM83D gene was evaluated to determine the protein levels of FAM83D in the human oesophageal squamous cell carcinoma ECA109 and KYSE30 cells using western blotting. MTS, clone formation, and Transwell assay were employed to examine the proliferation, survival ability and invasion of ECA109 and KYSE30 cells in vitro, respectively. We used flow cytometry assay to analyze distribution of cell apoptosis in different groups. Western blotting was used to examine the expression of cell metastasis-related molecules and apoptosis-related protein. Results:The strong expression rates of FAM83D, E-cadherin, and vimentin were 55%(38/69), 36%(25/69) and 61%(42/69) in the tumor tissues, respectively. FAM83D protein expression was significantly and negatively correlated with the expression of E-cadherin ( r=-0.350, P<0.01), and positively with the expression of vimentin ( r=0.470, P<0.01). Western blotting results demonstrated that silencing FAM83D gene significantly reduced the FAM83D protein expression ( P<0.01). MTS data demonstrated that FAM83D knockdown after irradiation significantly inhibited the proliferation of esophageal squamous cell carcinoma ECA109 and KYSE30 cells ( P<0.05). The data from the clone formation assay revealed that the radiosensitivity was increased after downragulation of FAM83D expression ( P<0.01). In addition, the invasive abilities of oesophageal carcinoma cells transfected with FAM83D shRNA after irradiation were significantly inhibited compared with those of the NC group ( P<0.01), followed by the downregulation of N-cadherin, vimentin, Snail, p-Akt and p-GSK-3β expression, and the upregulation of E-cadherin expression ( P<0.01). The apoptosis rate of tumor cells in FAM83D shRNA group after irradiation was markedly increased ( P<0.01), followed by a decrease of Bcl-2 and Mcl-1 expression and an increase of Cleaved caspase-3 expression ( P<0.01). Conclusions:FAM83D expressions was found to be closely related to the invasion and development of ESCC. Furthermore, siRNA interference technology inhibited the expression of FAM83D gene in oesophageal squamous cell carcinoma cells, reduced the proliferation, invasion of cells, induced cell apoptosis, and increased radiosensitivity, which may be associated with regulating the epithelial-mesenchymaltransition via Snail/Akt/GSK-3β signaling pathways.

ABSTRACT

Objective:To investigate the effects of combination of transcranial direct current stimulation (tDCS) and mirror therapy (MT) on upper limb motor function after stroke. Methods:From April, 2018 to March, 2019, 78 stroke inpatients were randomly assigned into tDCS group (n = 26), MT group (n = 26) and combined group (n = 26). All the patients received their related therapy, respectively, based on routine medicine and rehabilitation. Their motor-evoked potential cortical latency (CL) and central motor conduction time (CMCT) in affected brain area were measured before and four weeks after treatment, while they were assessed with Fugl-Meyer Assessment-Upper Extremity (FMA-UE) and modified Barthel Index (MBI). Results:All CL, CMCT, and the scores of FMA-UE and MBI improved significantly in all the groups after treatment (|t| > 2.609,P < 0.05), and improved more in the combined group than in both tDCS group and MT group (P < 0.05). Conclusion:Both tDCS and MT could improve excitability of cerebral cortex of the affected brain area and promote the recovery of upper limb motor function for patient after stroke, and it is more effective in combination mode.

ABSTRACT

Objective@#To investigate the application of the self-made semen quality control (QC) product in internal QC of computer-assisted sperm analysis (CASA).@*METHODS@#CASA was calibrated with high- and low-concentration commercially available semen QC product and meanwhile 15 samples of self-made mixed semen QC product were placed in 75 cryotubes containing liquid nitrogen, followed by CASA of the concentration, motility, curvilinear velocity (VCL), straight line velocity (VSL), average path velocity (VAP), linearity (LIN), wobble (WOB) and straightness (STR) of the sperm using standard procedures and 50 days of continuous monitoring. The Makler counting plate was used to measure the concentration and motility of the self-made sperm.@*RESULTS@#The coefficients of variation (CV) of the commercially available semen QC product at high and low concentrations were 6.18% and 7.85%, respectively. CASA showed that the concentration of the self-made QC product was (25.97 ± 1.41) ×10⁶/ml, with a CV of 5.42%, and the sperm motility, VCL, VSL, VAP, LIN, WOB and STR were (22.15 ± 1.75)% (CV = 7.9%), (59.18 ± 2.05) μm/s (CV = 3.46%), (26.79 ± 1.2) μm/s (CV = 4.48%), (34.98 ± 1.4) μm/s (CV = 4.01%), 46.81 ± 1.55 (CV = 3.3%), 60.52 ± 1.3 (CV = 2.15%) and 76.46 ± 1.98 (CV = 2.59%), respectively. The concentration and motility of the self-made sperm detected with the Makler counting plate were (34.39 ± 2.37) ×10⁶/ml (CV = 6.89%) and (38.04 ± 1.69)% (CV = 4.44%), respectively. Levey-Jennings QC charts were plotted for the indicators using the means and standard deviation.@*CONCLUSIONS@#The self-made internal QC product by liquid nitrogen cryopreservation is feasible and effective for monitoring the accuracy and precision of CASA-derived sperm concentration and motion parameters, and it has a smaller CV than the commercially available QC product in measuring sperm concentration.

ABSTRACT

Objective:To explore the effect of combining transcranial direct current stimulation (tDCS) with bilateral isokinematic training (BIT) to improve upper limb motor function after stroke.Methods:Sixty stroke survivors were randomly divided into a tDCS group, a BIT group and a tDCS + BIT group, each of 20. In addition to conventional medical treatment and rehabilitation training, the three groups were given the additional treatment their group names indicate for four weeks. Before and after the intervention, everyone′s motor evoked potential cortical latency (CL) and central motor conduction time (CMCT) were measured. Upper limb motor function was assessed using the Fugl-Meyer upper extremity assessment (FMA-UE) and the Hongkong edition of a functional test for the hemiplegic upper extremity (FTHUE-HK).Results:After 4 weeks of treatment the average CL and CMCT had decreased significantly in all three groups, with those of the combined group significantly shorter than the other two groups′ averages. The average FMA-UE and FTHUE-HK scores had increased significantly in all three groups compared to those before treatment, but those of the combined group were significantly superior to the other groups′ averages.Conclusions:tDCS combined with BIT can further improve the excitability of the cerebral cortex and promote the recovery of upper limb motor function.

ABSTRACT

To explore the mechanism hydroxysafflor yellow A (HSYA) biosynthesis and regulation, the effect of methyl jasmonate (MeJA) treatment on gene expression related to the biosynthesis of hydroxysafflor yellow A (HSYA) was analyzed, and expression differences in genes involved in HSYA biosynthesis in safflower of different colors was quantified. MeJA at concentrations of 0, 50, 100, and 200 μmol·L-1 was sprayed onto safflower florets to determine the optimal concentration of MeJA. Safflower was treated with 100 μmol·L-1 MeJA and florets were harvested 0, 3, 6, 12 and 24 h after treatment. The content of MeJA was determined by high performance liquid chromatography (HPLC). RNA was extracted from safflower florets treated with 100 μmol·L-1 MeJA for 6 h. The transcription of key genes involved in the biosynthesis of HSYA was quantified by qRT-PCR and differentially expressed genes were identified. The content of HSYA increased after treatment with MeJA, with 100 μmol·L-1 MeJA treatment for 6 h having the greatest effect on HSYA accumulation. qRT-PCR results showed that MeJA could significantly increase the transcription of HSYA biosynthesis genes including PAL2, PAL4, 4CL2, 4CL4, 4CL5, CHS3, CHS4 and CHI2. The content of HSYA differed between safflowers of different colors with a trend of red>orange-yellow>yellow>white. The results of qRT-PCR showed that the expression of CHS1 and CHI2 in red, orange and yellow safflower was significantly higher than that in white safflower. These results indicate that MeJA promotes the accumulation of HSYA by up-regulating the expression of genes involved in the biosynthesis of HSYA such as PAL2, PAL4, 4CL2, 4CL4, 4CL5, CHS3, CHS4 and CHI2, and the variation of HSYA content in safflower of different colors was related to a difference in the level of expression of CHS1 and CHI2.

ABSTRACT

The advantages of western medical research were analyzed and the differences between skin nerve stimulation in western medicine and acupuncturemoxibustion in TCM were compared, so as to inspire the scientific researches of acupuncture and moxibustion in China. The related literature was searched and the research basis, content and achievements of the American stimulating peripheral activity to relief condition (SPARC) program were systematically summarized. From the perspectives of theoretical system, stimulation site, stimulation method and mechanism of action, the similarities and differences between skin nerve stimulation in western medicine and acupuncturemoxibustion in TCM were compared. Through comparative analysis, it is found that the systematic construction of SPARC "high-resolution neural circuit map" is essentially the upgraded version of the traditional distribution map of meridians and acupoints in China, which is similar to the research on origin of nervous system and stimulation site of acupuncturemoxibustion of TCM. Under the impact of "localization of traditional Chinese medicine" in other countries, learning from the international advanced research technology, gathering top-level talents, and encouraging openness and innovation will be the necessary pathway to improve the quality of acupuncturemoxibustion research and master the power of knowledge initiative.

ABSTRACT

OBJECTIVE@#To observe the effect of electroacupuncture (EA) preconditioning on the expressions of tyrosine kinase Lyn and spleen tyrosine kinase (Syk) in mast cells of subcutaneous loose connective tissue in the rats with urticaria and explore the potential biological mechanism of EA in the intervention of urticaria.@*METHODS@#A total of 32 SD rats were randomized into a blank group, a model group, an EA group and a positive medication group, 8 rats in each one. Except of the blank group, the passive cutaneous anaphylaxis (PCA) was adopted to prepare the model of urticaria in the rats of the rest three groups. In the EA group, EA was applied to bilateral "Quchi" (LI 11), "Xuehai" (SP 10) and "Zusanli" (ST 36), with disperse-dense wave, 2 Hz/15 Hz in frequency and 1 mA in current intensity, once daily, for 20 min each time, consecutively for 7 days. In the positive medication group, loratadine (1 mg•kg•d) was for intragastric administration, once daily, consecutively for 7 days. The samples were collected for index detection 30 min after PCA antigen challenge in the rats of each group. Spectrophotometer was adopted to determine the effusion quantity of Evans blue in the allergized site of skin. HE staining was used to observe the morphological changes in the allergized site of skin. Toluidine blue staining was provided to observe mast cell degranulation in subcutaneous loose connective tissue in the allergized site of skin. Immunohistochemistry was applied to determine the protein expressions of Lyn and Syk during degranulation of mast cells.@*RESULTS@#In the rats of the odel group, the eipdermis of allergized site was thickening, cells were disorganized in hierarchy and inflammatory cells were infiltrated largely in the dermis. In the positive medication group and the EA group, the epidermis was getting thin, cell arrangement was clear and the inflammatory cell infiltration was obviously alleviated as compared with the model group. Compared with the blank group, the OD value of skin dye effusion quantity, the degranulation rate of mast cells and the positive expressions of Lyn and Syk were all increased in the model group (<0.01). Compared with the model group, the OD value of skin dye effusion quantity, the degranulation rate of mast cells and the positive expressions of Lyn and Syk were all reduced in the EA group and the positive medication group (<0.01). Compared with the positive medication group, the degranulation rate of mast cells was increased significantly in the EA group (<0.01).@*CONCLUSION@#Electroacupuncture at "Quchi" (LI 11), "Xuehai" (SP 10) and "Zusanli" (ST 36) reduces vascular permeability and gives play to the role of anti-allergy by the way of regulating and controlling the degranulation of mast cells in the rats with urticaria and the effect mechanism of electroacupuncture may be related to the inhibition of protein expressions of Lyn and Syk in mast cells.

Methods:From October, 2017 to August, 2018, 66 patients after stroke were randomly divided into routine group (n = 22), sling group (n = 22) and combined group (n = 22). All the groups accepted routine rehabilitation, while the sling group accepted sling exercise therapy based on routine group and the combined group accepted sling exercise therapy and Kinesio Taping. They were assessed with Berg Balance Scale (BBS) and Fugl-Meyer Assessment-Lower Extremities (FMA-LE), and their gait parameters were measured with Motion Analysis, before and four weeks after treatment. Results:There were obvious improvements in the BBS score, FMA-LE score and gait parameters in all the groups after treatment (P < 0.05), and it was ranked from better to worse as the combined group, the sling group and the routine group (P < 0.05). Conclusion:Sling exercise therapy combined with Kinesio Taping may further improve balance and walking for stroke patients.

ABSTRACT

Objective@#To evaluate the effect of X-ray radiation on cell proliferation, migration, survival ability and cell cycle of human esophageal squamous cell carcinoma after RNA interference-mediated down-regulation of HMGB1 gene expression.@*Methods@#The expression of HMGB1 at mRNA and protein levels in the human esophageal squamous cell carcinoma cell lines ECA109 and KYSE30 was determined using RT-PCR and Western blot assays. MTS and Transwell assays were employed to examine the proliferation and migration of ECA109 and KYSE30 cell lines. The cellular survival ability in vitro was assessed by clone formation assay. The cell cycle after X-ray radiation in different groups was detected by flow cytometry.@*Results@#The expression of HMGB1 at mRNA and protein levels in ECA109 and KYSE30 cells were markedly higher in a dose-dependent and time-dependent manner in the radiation group than that in the control group (all P<0.05). MTS results demonstrated that the proliferation of ECA109 and KYSE30 cells was obviously lower at each time point after radiation than that in the group without radiation (all P<0.01). The expression of HMGB1 at mRNA and protein levels was significantly inhibited in the HMGB1 siRNA group than those in the control and NC groups (both P<0.01). The data from the clone formation assay revealed that the radiosensitivity was significantly increased after down-regulation of HMGB1 expression (P<0.01). Transwell migration assay revealed that the number of migrating cells at the fourth hour after X-ray irradiation in the HMGB1 siRNA group was significantly lower than those in the control and negative groups (both P<0.01). In the HMGB1 siRNA group, the percentage of cells at G0/G1 phase was obviously higher, whereas the percentage of S phase was significantly lower than those in the control and NC groups, and the trend was even more significant after X-ray radiation (all P<0.01).@*Conclusion@#Inhibition of HMGB1 expression by siRNA can suppress the proliferation and migration of ECA109 and KYSE30 cells and enhance the radiosensitivity by increasing the cell cycle arrest at G0/G1 stage after X-ray irradiation in vitro.

ABSTRACT

Objective: To assess the infection status of Cryptosporidium spp. in the four common species of farmed animal (pigs, cattle, goats and geese) in the Hainan Island of China, followed by molecular characterization of the parasite. Methods: During March to July 2019, 864 DNA were extracted from the fecal samples of 188 pigs, 341 goats, 130 cattle, and 169 geese which were collectd from four, five, six, and three cities of the Hainan Province, China, respectively. The species/genotypes and subtypes of Cryptosporidium were identified by employing nested-PCR amplification of the SSU rRNA and the 60 kDa glycoprotein (gp60) genes of the parasite, respectively. Results: Cryptosporidium was identified in 68 (7.9%) out of 864 animals, with 45 (13.2%) goats, 13 (6.9%) pigs, 4 (3.1%) cattle, and 6 (3.6%) geese. Cryptosporidium (C.) xiaoi (n=24) and C. ubiqutium (n=21) were identified in goats; C. suis (n=7) and C. scrofarum (n=6) in pigs; C. parvum (n=3) and C. occultus (n=1) in cattle; and C. baileyi (n=1) and Cryptosporidium goose genotype I(n=3) in geese. The 21 C. ubiqutium isolates shared a same subtype XII a, and the subtype of three C. parvum was II dA15G1. Conclusions: We present for the prevalence of the Cryptosporidium in cattle, goats, pigs and geese from the Hainan Island of China for the first time. The molecular characterization of the Cryptosporidium isolates obtained here propose that the goats, cattle and pigs are potential sources of C. ubiqutium, C. parvum, and C. suis infections, in humans.
