ABSTRACT

OBJECTIVE@#To observe the efficacy and complications of one-stage tumor resection to treat primary sacral neurogenic tumors and to discuss some details in the clinically relevant anatomy.@*METHODS@#A retrospective analysis of 26 patients with neurogenic turors of the sacral spine who were surgically treated from January 2001 to January 2018, including 16 males and 10 females, aged from 21 to 69 years old with an average age of (39.3±10.9) years old. The courses of diseases ranged from 3 to 56 months with an average of (17.9±10.1) months. The diameters of presacral components ranged from 3.3 to 19.6 cm with an average of (8.7±4.1) cm. The proximal margin of presacral lesions was above the L5S1 level in 6 cases, and lower than L5S1 in 20 cases. A posterior incision approach for one-stage complete resection of the tumor was used firstly, and an anterior approach was combined when necessary. Spinal-pelvic reconstruction with the modified Galveston technique was also carried out in relevant cases. Whether to preserve the tumor-involved nerve roots depended on the situation during the operation. The operation time, intraoperative blood loss, pain relief, and complications were recorded. The lumbosacral spine stability and sacral plexus neurological function were evaluated during postoperative follow-up, and local recurrence and distant metastasis were examined as well.@*RESULTS@#Total excision was achieved in all 26 patients, with an operation time of (160.4±35.3) mins and an intraoperative blood loss of (1 092.3±568.8) ml. Tumors have been removed via a posterior-only approach in 21 cases and via combined anterior/posterior approaches in 5 cases. The diameter of presacral masses components ranged from 11.3 to 19.6 cm with an average of (15.1±3.2) cm in patients with combined anterior/posterior approaches, and ranged from 3.3 to 10.9 cm with an average of (7.2±2.4) cm in patients with a posterior-only approach. Five of the six patients whose proximal margin of presacral masses was above the L5S1 level adopted combined anterior/posterior approaches, and 20 patients lower than the L5S1 level adopted the posterior-only approach. All the patients were followed up for 6 to 82 months with an average of(45.4±18.2)months. Postoperative lumbosacral pain and lower extremity radicular pain were significantly relieved, and sensation, muscle strength and bowel and bladder function were also improved to varying degrees. The postoperative early complications included superficial wound infection in 1 case and cerebrospinal fluid leakage in 2 cases. Pathology confirmed 17 cases of schwannoma, 7 cases of neurofibroma and 2 cases of malignant schwannoma. Local recurrence was observed in two cases of benign neurogenic tumors. One patient with a malignant nerve sheath tumor had lung metastasis, who died 20 months after the operation. In 17 cases of upper sacral neurogenic tumors, 4 cases did not undergo spinal-pelvic reconstruction with internal fixation, of which 2 cases suffered from postoperative segmental instability. Tumor-involved nerve roots were resected during surgery in 7 cases. One of these patients who had S2 and S3 nerve roots sacrificed simultaneously had an impaired bladder and bowel function postoperatively, and did not recover completely. In the other 6 cases, the neurological function was not damaged obviously or recovered well.@*CONCLUSION@#The posterior approach can directly expose the lesions, and it is also convenient to deal with nerve roots and blood vessels. The operation time, intraoperative blood loss, degree of symptom relief, complication rate, and recurrence and metastasis rate can be controlled at an appropriate level. It is a safe and effective surgical approach. When the upper edge of the presacral mass is higher than the L5S1 level or the diameter of the presacral mass exceeds 10 cm, an additional anterior approach should be considered. The stress between the spine and pelvis is high, and internal fixation should be used to restore the mechanical continuity of the spine and pelvis during resection of neurogenic tumors of the high sacral spine. Most of the parent nerve roots have lost their function. Resection of a single parent nerve root is unlikely to cause severe neurological dysfunction, while the adjacent nerve roots have compensatory functions and should be preserved as much as possible during surgery.

ABSTRACT

Objective: To investigate the association between metabolically healthy obesity and the incident risk of stroke in people aged ≥40 years from rural areas of Henan Province. Methods: During 2007 to 2008, 20 194 residents aged ≥18 years were selected for baseline examination by random cluster sampling and 17 265 participants were followed up during 2013 to 2014. According to the aim of current study, a total of 11 864 eligible subjects were included in this post-hoc analysis. Depending on body mass index and metabolic status, subjects were divided into four groups: metabolically healthy normal weight, metabolically healthy obesity, metabolically abnormal normal weight and metabolically abnormal obesity. Multivariate logistic regression model was used to analyze the relationship between metabolically healthy obesity and the risk of stroke. Results: The median (Q1, Q3) age of study participants was 54(46, 61) years, and 4 526 participants were men. During the mean follow-up of 6 years, the cumulative incidence of stroke was 7.16%. The incidence of stroke in metabolically healthy normal weight, metabolically healthy obesity, metabolically abnormal normal weight, and metabolically abnormal obesity were 3.73%, 4.61%, 8.99% and 9.38%, respectively (χ²=117.458, P<0.001). After adjusting possible confounding factors, compared with metabolically healthy normal weight, the risk of stroke was significantly increased in the metabolically healthy obesity group, metabolically abnormal normal weight group and metabolically abnormal obesity group with the odds ratio (OR) and 95% confidence interval (CI) of 1.52(1.10-2.12), 2.11(1.61-2.77) and 2.78(2.18-3.55), respectively. Stratified analysis showed that the risk of stroke was significantly higher in metabolically healthy obesity people aged 40-59 years compared with metabolically healthy normal weight group (OR=2.12, 95%CI: 1.36-3.30). Conclusion: Metabolically healthy obesity, metabolically abnormal normal weight and metabolically abnormal obesity are positively associated with the risk of stroke.

ABSTRACT

The interleukin (IL) -23/IL-17 axis is the main pathway in the pathogenesis of plaque-type psoriasis vulgaris, and IL-17A plays a key role in the relevant immune pathways. IL-17A mediates overlapping inflammatory pathways in atherosclerosis and psoriasis, promotes inflammation, coagulation and thrombosis, and plays an important role in the occurrence and development of cardiovascular comorbidities in patients with psoriasis. Inhibiting the inflammatory effect of IL-17A can reduce the incidence and mortality of cardiovascular comorbidities in patients with severe psoriasis. This review summarizes recent research progress in IL-17A-mediated systemic inflammation and cardiovascular comorbidities in patients with psoriasis, and provides a reference for prevention and reduction of cardiovascular comorbidities in patients with psoriasis in clinical practice.

ABSTRACT

Objective:To study the stability and influencing factors of potassium iodate iodized salt that can be sold in Jilin Province.Methods:In November 2020, 10 large supermarkets were randomly selected in Jilin Province, and two kinds of potassium iodate iodized salts were randomly selected in each supermarket, with five copies of each kind, a total of 100 samples of iodized salt, and the iodine content was determined by spectrophotometry (iodide-starch blue light method). Iodized salt samples were classified according to different salt species (mine salt, sea salt and lake salt) and different production processes (refined salt and non-refined salt). The salt was stored at room temperature, and the iodine content in the salt was measured at 0, 10 and 20 days after opening the packaging. The iodine content attenuation rates of different salt species and different production processes were compared.Results:The mine salt, sea salt and lake salt in iodized salt samples were 45, 45 and 10 portions, respectively. The iodine contents of the 0th day of storage [(19.89 ± 1.38), (20.62 ± 1.91), (19.78 ± 1.01) mg/kg] were compared, and the difference was not statistically significant ( F = 2.57, P = 0.093). On the 10th day, the iodine content of mine salt was lower than that of sea salt and lake salt, and the differences were statistically significant ( P < 0.05); on the 20th day, the iodine content of mine salt was lower than that of sea salt, and the difference was statistically significant ( P < 0.05). There was a significant difference in the iodine content of mine salt stored at 0, 10 and 20 days ( F = 90.62, P < 0.001). The iodine content of sea salt and lake salt on the 20th day was significantly lower than that on the 0th and 10th day, and the differences were statistically significant ( P < 0.05). The iodine content attenuation rates of mine salt, sea salt and lake salt on the 0 - 10 days was compared with that on the 10 - 20 days, and the differences were statistically significant ( Z = 2.24, 2.94, 2.80, P < 0.05). There was a significant difference in the iodine content attenuation rates of mine salt, sea salt and lake salt during the 0 - 10 days of storage ( Z = 24.05, P < 0.001), there was no statistically significant difference in the iodine content attenuation rates on 10 - 20 days ( Z = 5.86, P = 0.053). There was no significant difference in iodine content attenuation rates between refined salt and non-refined salt on 0 - 10, 10 - 20 days ( Z = 1.16, 0.28, P > 0.05). There was no statistical significant difference in the iodine content attenuation rates of refined salt and non-refined salt on the 0 - 10 days compared with those of 10 - 20 days ( Z = 0.76, 1.90, P > 0.05). Conclusions:Iodine loss occurs at 20 days after opening the packaging of iodized salt in Jilin Province. The attenuation of iodine content is less affected by salt species and production processes. It is recommended to eat iodized salt within 20 days after opening the packaging.

ABSTRACT

This study establishes and optimizes the physiologically based pharmacokinetics (PBPK) model for dapagliflozin, predicts the drug distribution into relevant tissues, and calculates the inhibitory effect on the sodium-glucose cotransporters (SGLTs) in the intestine and renal proximal tubule. Based on literature data, a PBPK model for oral administration in healthy adults was established and the predicted blood concentration-time curve characteristics, the main pharmacokinetic parameters (PK), and drug excretion in urine were compared with the published data. To verify and optimize the model and verify the accuracy of the tissue distribution and concentration predictions, a pharmacodynamics model (PD) was established. Urine glucose excretion (UGE) was simulated at the corresponding times. The characteristics of the drug-time curve predicted by the model are similar to those of the measured curve, and the ratio of the main PK parameters to the measured values is within a two-fold range; the accuracy of the established PBPK model is good. The maximal inhibition obtained with 10 mg of dapagliflozin on the duodenum and jejunum segment sodium-glucose co-transporter 1 (SGLT1s) was 1.6%-4.7%, and the inhibition rate of the sodium-glucose co-transporter 2 (SGLT2s) in the proximal tubule of the kidney was as high as 99.9%. At a dose of 10 mg, dapagliflozin delayed intestinal glucose absorption while occupying most of the sites (99.9%) of the renal sodium-glucose cotransporter 2 and inhibiting its glucose reabsorption. This physiological-pharmacokinetic model for dapagliflozin in healthy adults can provide meaningful guidance for exploring pharmacological mechanisms and potential toxicity of gliflozin by simulating drug distribution in different tissues.

ABSTRACT

Objective@#The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.@*Methods@#The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.@*Results@#A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).@*Conclusion@#An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

ABSTRACT

Objective:To investigate the expression of microRNA (miR) -26a in human skin fibroblasts during photoaging induced by ultraviolet A (UVA) , and to evaluate the effect of up-or down-regulation of miR-26a expression on the methylation level of the whole genome, the target gene enhancer of zeste homolog 2 (EZH2) and cell aging.Methods:Some human skin fibroblasts were irradiated with 10 J/cm 2 UVA once a day for 7 consecutive days, RNA was extracted on days 0, 3 and 7, and real-time quantitative reverse PCR (RT-PCR) was performed to determine the expression of miR-26a; miR-26a mimics and inhibitors were transfected into fibroblasts to up-or down-regulate the expression of miR-26a respectively, and fluorescence microscopy and RT-PCR were performed to determine the expression of miR-26a and evaluate the transfection efficiency. Some human skin fibroblasts were divided into 6 groups: blank control group receiving no treatment, UVA group treated with UVA irradiation according to the above method, miR-26a mimic group transfected with miR-26a-mimics, UVA+miR-26a mimic group transfected with miR-26a-mimics followed by UVA irradiation, miR-26a inhibitor group transfected with miR-26a inhibitors, UVA+miR-26a inhibitor group transfected with miR-26a inhibitors followed by UVA irradiation. On day 7, cells in each group were collected after the end of UVA irradiation. Then, flow cytometry was performed to detect cell cycle, DNA methylation quantitative detection kit was used to detect the methylation level of whole genome, RT-PCR was conducted to determine the mRNA expression of EZH2 (a histone-lysine N-methyltransferase enzyme) , DNA methyltransferase 1 (DNMT1) and miR-26a, and Western blot analysis was performed to determine the protein expression of EZH2 and DNMT1. Statistical analysis was carried out by using one-way analysis of variance and least significant difference- t test. Results:Compared with the unirradiated control group, the expression of miR-26a gradually increased in the UVA irradiation group over time during the culture, and there was a significant difference in the expression of miR-26a between the two groups after 7 days of UVA irradiation ( t=5.295, P < 0.05) . Strong fluorescence signals were observed in the miR-26a mimic-or miR-26a inhibitor-transfected fibroblasts, suggesting a high transfection efficiency. Flow cytometry showed that the proportion of cells at G1 phase significantly differed among the blank control group, UVA group, miR-26a mimic group, UVA+miR-26a mimic group, miR-26a inhibitor group, and UVA+miR-26a inhibitor group (52.82% ± 2.56%, 78.56% ± 4.34%, 53.63% ± 3.13%, 89.52% ± 4.17%, 54.39% ± 3.86%, 65.34% ± 4.78%, respectively; F=46.728, P < 0.01) , and significantly higher in the UVA group than in the blank control group ( t=8.848, P < 0.01) , higher in the UVA+miR-26a mimic group than in the miR-26a mimic group and UVA group ( t=11.922, 3.154, P < 0.01, < 0.05, respectively) , and higher in the UVA+miR-26a inhibitor group than in the miR-26a-inhibitor group ( t=3.087, P < 0.05) , but significantly lower in the UVA+miR-26a inhibitor group than in the UVA group ( t=3.547, P < 0.05) . Detection of the genome-wide methylation level showed that the methylation level ( A450 value) significantly differed among the above groups (0.676 ± 0.024, 0.323 ± 0.043, 0.506 ± 0.035, 0.169 ± 0.024, 0.602 ± 0.036, 0.422 ± 0.029, respectively, F=97.402, P < 0.01) , and significantly lower in the UVA group than in the blank control group ( P < 0.01) , lower in the UVA+miR-26a mimic group than in the miR-26a mimic group and UVA group (both P < 0.01) , and lower in the UVA+miR-26a inhibitor group than in the miR-26a inhibitor group ( P < 0.01) , but significantly higher in the UVA+miR-26a inhibitor group than in the UVA group ( P < 0.05) . RT-PCR and Western blot analysis showed significant differences in the mRNA and protein expression of EZH2 and DNMT1 respectively among the 6 groups (both P < 0.05) , which were significantly lower in the UVA group than in the blank control group ( P < 0.05) , lower in the UVA+miR-26a mimic group than in the miR-26a mimic group and UVA group (both P < 0.05) , and lower in the UVA+miR-26a inhibitor group than in the miR-26a inhibitor group ( P < 0.05) , but significantly higher in the UVA+miR-26a inhibitor group than in the UVA group ( P < 0.05) . Conclusion:In the UVA irradiation-induced photoaging of skin fibroblasts, miR-26a expression was up-regulated, cellular proliferative activity and genome-wide methylation level decreased; up-regulation of miR-26a expression could down-regulate the expression of its target gene EZH2 and methylation-related gene DNM1, and promote cell photoaging, while down-regulation of miR-26a expression could up-regulate the expression of EZH2 and DNMT1, and inhibit cell photoaging.

ABSTRACT

The present study explored the therapeutic potential of hydrogen sulfide (H2 S) in restoring aging-induced loss of cardioprotective effect of remote ischemic preconditioning (RIPC) along with the involvement of signaling pathways. The left hind limb was subjected to four short cycles of ischemia and reperfusion (IR) in young and aged male rats to induce RIPC. The hearts were subjected to IR injury on the Langendorff apparatus after 24 h of RIPC. The measurement of lactate dehydrogenase, creatine kinase and cardiac troponin served to assess the myocardial injury.The levels of H2S, cystathionine β-synthase (CBS), cystathionine γ-lyase (CSE), nuclear factor erythroid 2-related factor 2 (Nrf2), and hypoxia-inducible factor (HIF-1α) were also measured. There was a decrease in cardioprotection in RIPC-subjected old rats in comparison to young rats along with a reduction in the myocardial levels of 2, CBS, CSE, HIF-1α, and nuclear: cytoplasmic Nrf2 ratio. Supplementation with sodium hydrogen sulfide (NaHS, an H2S donor) and l-cysteine ( H 2S precursor) restored the cardioprotective actions of RIPC in old hearts. It increased the levels of H2S, HIF-1α, and Nrf2 ratio without affecting CBS and CSE. YC-1 (HIF-1α antagonist) abolished the effects of NaHS and l-cysteine in RIPC-subjected old rats by decreasing the Nrf2 ratio and HIF-1α levels, without altering 2.The late phase of cardioprotection of RIPC involves an increase in the activity of H2S biosynthetic enzymes, which increases the levels of H2S to upregulate HIF-1α and Nrf2. H2S has the potential to restore aging-induced loss of cardioprotective effects of RIPC by upregulating HIF-1α/Nrf2 signaling.

ABSTRACT

Objective:To evaluate the efficacy and safety of recombinant human tumor necrosis factor-α receptorⅡ: IgG Fc fusion protein (rhTNFR:Fc) in the treatment of drug-induced toxic epidermal necrolysis (TEN) .Methods:From 2009 to 2018, 22 patients with TEN were enrolled from 8 centers such as the Second Affiliated Hospital of Soochow University, including 10 males and 12 females, whose age ranged from 22 to 75 years. These patients were subcutaneously injected with rhTNFR:Fc at a dose of 25 mg once every 3 days for 6 - 8 consecutive sessions, and the initial dose was doubled. The drug eruption area and severity index (DASI) score and DASI improvement indices (DASI50, DASI75 and DASI90) were assessed before treatment and on days 4, 7, 10, 13, 16, 19, 22 and 25 after treatment; cytometric bead array (CBA) technology was used to detect the level of tumor necrosis factor (TNF) -α in peripheral blood and blister fluid samples. During the treatment, body temperature, rash changes, liver and kidney function of patients were monitored, and adverse reactions were recorded. Statistical analysis was carried out by using repeated measures analysis of variance, paired t test and Pearson correlation analysis. Results:Of the 22 patients, the temperature stopped rising in 20 patients without infections 24 - 72 hours after the first treatment, and returned to normal after 48 - 120 hours. Among the 22 patients, new blisters stopped appearing 24 - 48 hours after the first treatment, the skin color changed from bright red to dark purple after 48 - 96 hours, and most skin lesions subsided after 2 weeks. After 2 - 4 weeks of treatment, levels of alanine aminotransferase and aspartate aminotransferase returned to normal in 19 patients with abnormal liver function. After 4 - 13 days of treatment, levels of creatinine and urea nitrogen stopped rising in 7 patients with abnormal renal function. During the treatment, the DASI score of the 22 patients gradually decreased ( F = 532.81, P < 0.01) , from 53.64 ± 8.67 before treatment to 2.05 ± 1.21 on day 25 after treatment ( t = 26.60, P < 0.001) . On day 10 after treatment, 22 patients (100%) achieved DASI50; on day 19, 22 (100%) achieved DASI75; on day 25, 20 (90.90%) achieved DASI90. The level of TNF-α in peripheral blood of the 22 patients gradually decreased along with the extension of treatment duration, from 33.95 ± 27.90 ng/L before treatment to 2.38 ± 0.79 ng/L on day 25. Before treatment, the level of TNF-α in blister fluid of 15 patients was 111.99 ± 99.41 ng/L, and the ratio of blister-fluid TNF-α level to peripheral blood TNF-α level was 1.83 - 28.21. Before treatment, no correlation was observed between the serum level of TNF-α and DASI score in the 22 patients ( P = 0.10) , while the blister-fluid TNF-α level was positively correlated with DASI score in the 15 patients ( r = 0.59, P = 0.02) . No acute adverse reactions were observed during the treatment. All the 22 patients completed the treatment and were discharged with complete recovery. During 6 months of follow-up after discharge, no recurrence or any complication was observed. Conclusion:rhTNFR:Fc is effective and safe for the treatment of drug-induced TEN.

ABSTRACT

A 89-year-old female patient presented with skin lesions of the groin, vulva and intergluteal sulcus for 10 months, and blisters for 3 weeks. Skin examination revealed the red-white hyperplastic plaques on the groin, vulva and intergluteal sulcus, on which mung-bean- to pea-sized erosions and blisters scattered, and several similar blisters were scattered on the right axilla and right leg, some of which were broken and covered with crusts. Histopathological examination of the skin lesion on the intergluteal sulcus showed thickened spinous layer without acantholysis, subepidermal fissures and blisters in some areas, focal papillary dermal edema with eosinophil infiltration, and perivascular infiltration composed mainly of lymphocytes in the superficial dermis. Direct immunofluorescence assay showed linear deposition of IgG and C3 at the epidermal basement membrane zone, clustered deposition of IgM in the dermis, but no IgA deposition. Indirect immunofluorescence on salt-split skin revealed that IgG and C3 were deposited on the epidermal side. Enzyme linked immunosorbent assay (ELISA) showed that serum levels of anti-BP180 and anti-BP230 antibodies were 26.92 U/ml and 68.17 U/ml respectively, and those of anti-desmoglein 1 (Dsg1) and anti-Dsg3 antibodies were normal. The patient was diagnosed with pemphigoid vegetans. After the treatment with oral methylprednisolone combined with topical halometasone ointment and tacrolimus 0.03% ointment, the skin lesions gradually subsided.

ABSTRACT

Based on dehydrogenation of monocrotaline-induced Beagle dog model of pulmonary hypertension (PH), GC-TOF-MS metabolomics technique was used to identify potential biomarkers and biologically significant changes in the serum. Pattern recognition method was used for processing metabolomics data to compare PH Beagle dogs (n=11) versus healthy controls (n=8). The results show that 514 compounds were detected in the serum. The profiles of PH models and healthy controls can be distinguished clearly, indicating that there are significant differences in the metabolic profiles. Data analysis revealed 15 types of potential biomarkers, including amino acids glycine and 3-cyanoalanine, glucose, fructose, 1-monopalmitic acid glycerin, and malic acid. Diversified metabolites and their metabolic pathways have been analyzed. We found that different degrees of turbulence and disorganization occurred in glyoxylate and dicarboxylate metabolism, TCA cycle, starch and sucrose metabolism pathways in the Beagle dogs. A soluble guanylate cyclase activator, 4,6-diamino-2-[1-(3-fluorothiophen-2-yl)methyl-1H-pyrazolo[3,4-b]pyridin-3-yl]-5-pyrimidinyl-N-methyl methyl carbamate (sGC003), was administered (n=15) for comparison with the model and the control. We found that three groups were clearly clustered, indicating that there were differences in the three groups of metabolites. ANOVA statistical analysis results suggested that sGC003 exhibited pharmacodynamic effect, and at the same time, it also changed the endogenous metabolites to some extent. This study laid a foundation for the application of metabolomics in early diagnosis of pulmonary hypertension and provided experimental evidence for the application of sGC003 compound. In this study, the program of animal testing had been approved by Committee on the management of experimental animal in the Beijing Rixin Technology Co. Ltd.

ABSTRACT

OBJECTIVE@#To explore the relationship between the expression levels of JARID1B,Hes1 and MMP-9 genes and the stages of chronic myelogenous leukemia(CML) and the curative effect of imatinib mesylate (IM).@*METHODS@#Peripheral blood samples of 15 cases of CML in chronic phase and 10 cases of CML in progressive phase were collected from the Hematology Department of Taihe Hospital affiliated to Hubei University of Medicine and 15 cases of healthy people in the Physical Examination Center. CML patients were divided into effective group and ineffective group based on the efficacy after treatment with IM, then real-time PCR was used to detect the expression levels of JARID1B, Hes1 and MMP-9 mRNA, finally, the differences in the level of gene expression and their correlations with CML stages and IM curative efficacy were analysed.@*RESULTS@#The expression levels of Hes1 and MMP-9 in initially diagnosed patients in chronic and progressive phase without IM treatment were significantly higher than those of health people(P<0.05). There was no significant difference in the expression level of JARID1B between chronic phase patients and health people(P>0.05), but the expression level of JARID1B in the progressive phase patients was higher than that of health people (P<0.05). The expression levels of JARID1B and Hes1 in the IM-effective group were not significantly different from those in the IM-ineffective group (P=0.85,P=0.82), while the expression level of MMP-9 in the IM-effective group [JP2]was significantly lower than that in the IM-ineffective group(P<0.05).@*CONCLUSION@#The expression levels of JARID1B Hes1 and MMP-9 relate with the different phase of CML; The expression levels of JARID1B and Hes1 have not significant relationship with IM curative efficacy, the MMP-9 gene expression level relates with IM curative efficacy.

ABSTRACT

Objective To investigate the expressions,roles,and clinical significance of microRNA-365(miR-365)and E74-like factor 4(ELF4)in cervical cancer. Methods The expressions of miR-365 in normal cervical tissues(n=34),cervical intraepithelial neoplasia 1(CIN 1)(n=31),cervical intraepithelial neoplasia2-3(CIN 2-3)(n=37),squamous cell carcinoma of the cervix(SCC)(n=33),and three cervical cancer cell lines(C33A cells,Hela cells,and SiHa cells)were detected by real-time quantitative polymerase chain reaction(qPCR).Bioinformatic prediction and luciferase reporter gene assay were performed to verify whether ELF4 was a direct target of miR-365.Western blot and immunohistochemistry were used to detect ELF4 expression in cervical cancer cells and in different pathological cervix tissues.CCK8 assay was used to detect the effect of overexpression or inhibition of miR-365 on the proliferation of cervical cancer cells at different time points.The relationships among the miR-365 expression,ELF4 expression,and clinicopathological parameters of cervical cancer were analyzed by correlation analysis. Results qPCR results showed that compared with the normal cervical cell HcerEpic,the expressions of miR-365 in CIN1,CIN2-3,and cervical cancer tissues gradually decreased with the increased pathologic grade,and its expressions also decreased in different cervical cancer cell lines.The luciferase reporter gene assay confirmed that ELF4 was the direct target of miR-365.Western blot showed that the expression of ELF4 increased in all three cervical cancer cell lines compared with normal cervical epidermal cell(P=0.013,P=0.002,P=0.004).Immunohistochemistry showed that ELF4 expression was up-regulated in CIN and cervical cancer tissues.CCK8 assay showed that overexpression of miR-365 inhibited cell proliferation,while inhibition of miR-365 promoted the proliferation of three cervical cancer cells(PConclusion The decreased expression of miR-365 in human cervical cancer cells relieves its inhibitory effect on ELF4,which promotes the proliferation of cervical cancer cells and the formation of tumor.
