ABSTRACT
Objective:To explore the correlation between abnormal expression of serum 25(OH)D and immune-related fac-tors and subclinical atherosclerosis(AS)in patients with impaired glucose regulation.Methods:A total of 142 patients with im-paired glucose regulation admitted to Zaozhuang Municipal Hospital from December 2019 to April 2021 were selected.The patients with impaired glucose regulation were selected as the control group(n=86)and patients with subclinical atherosclerosis were selected as the observation group(n=56)according to carotid ultrasound examination and bramolecular pulse wave conduction velocity.The serum 25(OH)D and immune factors were compared between the two groups.Carotid ultrasound was used to measure the carotid inti-media thickness,and Pearson method was used to determine the correlation between the intimedia thickness,25(OH)D and immune factors.Baseline data and hematological indicators were collected,univariate and multivariate Logistic regression analysis was per-formed to determine the influencing factors of subclinical atherosclerosis,and ROC curve was used to evaluate the diagnostic efficacy of serum 25(OH)D and immune factors in subclinical atherosclerosis.Results:The serum 25(OH)D[(24.01±4.87)mmol/L vs(30.74±5.01)mmol/L,t=7.909,P=0.000)in the observation group was significantly lower than that of control group.TNF-α[(48.32±8.02)ng/L vs(33.21±9.00)ng/L,t=10.199,P=0.000)and IL-6[(41.22±9.43)ng/L vs(30.21±7.01)ng/L,t=7.492,P=0.000)in ob-servation group were significantly higher than those in control group.Carotid intima-media thickness was negatively correlated with se-rum 25(OH)D(r=-0.428,P<0.001),and was positively correlated with serum TNF-α and IL-6(r=0.574,0.577,P<0.001).Logis-tic regression analysis showed that serum 25(OH)D(OR=0.520,95%CI:0.401~0.675),serum TNF-α(OR=1.667,95%CI:1.131~2.457)and serum IL-6(OR=1.478,95%CI:1.213~1.802)were the influencing factors of subclinical atherosclerosis.ROC curve showed that the optimal cut-off value of serum 25(OH)D was 28.32 mmol/L,and the corresponding sensitivity,specificity and AUC were 69.64%,70.93%and 0.803(95%CI:0.749~0.855),respectively.The critical value of serum TNF-α was 40.56 ng/L,corre-sponding sensitivity was 71.43%,specificity was 72.09%,and AUC was 0.761(95%CI:0.717~0.823).Serum IL-6 cut-off value was 36.13 ng/L,corresponding sensitivity was 60.71%,specificity was 60.47%,and AUC was 0.627(95%CI:0.566~0.702).The sensitivity,specificity and AUC of regression analysis were 85.71%,81.40%and 0.889(95%CI:0.830~0.915).Conclusion:Serum 25(OH)D and immune-related factors alone and in combination can effectively predict the occurrence of subclinical atherosclerosis,which is correlated with carotid intima-media thickness,and serum 25(OH)D and immune-related factors are predictors of subclinical atherosclerosis.
ABSTRACT
Objective:To observe the value of superb microvascular imaging(SMI)combined with contrast-enhanced ultrasound(CEUS)in the differential diagnosis of benign and malignant superficial enlarged lymph nodes.Methods:A total of 82 patients with superficial enlarged lymph nodes who admitted to the Fourth Hospital of Qinhuangdao City from March 2020 to June 2022 were selected.All patients underwent SMI and CEUS examinations,and the ultrasound-guided needle biopsy was used as the"gold standard",and Kappa values was used to analyze the consistencies of single SMI and CEUS,and the combination of them with the"gold standard"in diagnosing benign and malignant superficial enlarged lymph nodes.Results:The results of ultrasound-guided needle biopsy showed that 34 superficial enlarged lymph nodes were benign lymph nodes and 63 superficial enlarged lymph nodes were malignant lymph nodes in 97 superficial enlarged lymph nodes of 82 patients.The results of SMI examination showed that 37 superficial enlarged lymph nodes were benign lymph nodes and 60 superficial enlarged lymph nodes were malignant lymph nodes in 97 superficial enlarged lymph nodes.The results of consistency analysis indicated that SMI has favorable value in differential diagnosis of benign and malignant superficial enlarged lymph nodes,which has better consistency with needle biopsy(Kappa=0.712).The results of CEUS examination showed that 36 cases of the 97 superficially enlarged lymph nodes were benign lymph nodes and 61 cases were malignant lymph nodes.The results of consistency analysis indicated that CEUS has better value in differential diagnosis of benign and malignant superficial enlarged lymph nodes,which has higher consistency with needle biopsy(Kappa=0.821).The results of SMI combined with CEUS examination showed that 35 cases of 97 superficial enlarged lymph nodes were benign lymph nodes and 62 cases were malignant lymph nodes.The result of consistency analysis indicated that SMI combined with CEUS has better value in differential diagnosis of benign and malignant superficial enlarged lymph nodes,and has higher consistency with needle biopsy(Kappa=0.886).Conclusion:Both SMI and CEUS examinations have better value in differential diagnosis of benign and malignant superficial enlarged lymph nodes,and the combination of them can further improve the consistency with result of pathological examination,and enhance the diagnostic value,which has a certain guidance significance in clinical screening malignant lymph nodes.
ABSTRACT
Objective To investigate the expression of MutS homolog 3(MSH3)in oral squamous cell carcinoma and its significance.Methods The MSH3 protein expression was examined by immunohistochemistry in 20 normal oral mucosa and 60 oral squamous cell carcinoma tissues.Results Our results showed that MSH3 expression in oral squamous cell carcinoma tissues was lower than normal oral mucosa.The MSH3 expression in oral squamous cell carcinoma tissues with better differentiation was higher than that with worse differentiation.The positive MSH3 expression decreased from oral squamous cell carcinoma patients without lymph nodal metastasis to that with metastasis.MSH3 expression was not related to the patients'gender,age,tumour location or size.Conclusion Downregulation of MSH3 is consistent with poorly differentiation and nodal metastasis in oral squamous cell carcinoma.MSH3 may play a significant role in the malignant progression of oral squamous cell carcinoma.
ABSTRACT
OBJECTIVE To study the effects of Hugan buzure formula (HBF) on intrahepatic cholestatic liver injury in rats and its potential mechanism. METHODS Rats were randomly divided into control group, model group, ursodeoxycholic acid (UDCA) group (positive control, 60 mg/kg ) and HBF low-dose, middle-dose and high-dose groups (HBF-L, HBF-M, HBF-H groups, 0.4, 0.8, 1.6 g/kg ), with 6 rats in each group. The rats in each drug group were given the corresponding drug solution intragastrically, once a day, for 7 consecutive days. The rats in the control group and the model group were given equal volumes of water intragastrically. On the 5th day, except for the control group, the rats in other groups were single intragastrically administered with alpha-naphthyl isothiocyanate olive oil solution (100 mg/kg) to establish the model. After 48 h of modeling, the contents of liver function indexes (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total bile acid, total bilirubin, direct bilirubin) and oxidative stress indexes [malondialdehyde (MDA), glutathione (GSH), superoxide dismutase] in serum of rats were detected; the pathological changes of liver tissue were observed. The mRNA expressions of inflammation-related factors [tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β)] and farnesoid X receptor (FXR) signaling pathway-related factors [FXR, small heterodimer partner (SHP), multidrug resistance protein 2 (MRP2), bile salt export pump (BSEP), Na+-taurocholate cotransporting polypeptide (NTCP), organic anion-transporting polypeptide 2 (OATP2) and cholesterol 7α-hydroxylase (CYP7A1)], the expressions of FXR signaling pathway-related proteins (FXR, MRP2, BSEP, NTCP) and nuclear factor- κB p65 (NF- κB p65) in liver tissue were detected.RESULTS Compared with the model group, the contents of liver function indexes and the level of MDA in serum, the mRNA expressions of the above inflammation-related factors and CYP7A1, and the relative expression of NF-κB p65 in liver tissue were significantly decreased; the levels of GSH in serum, the mRNA expressions of FXR, SHP, MRP2, BSEP, NTCP and OATP2, and the relative expressions of FXR, MRP2, BSEP and NTCP in liver tissue were significantly increased (P<0.05 or P<0.01); the pathological changes of liver tissue were significantly improved. Only some indexes in HBF-L group, HBF-M group and UDCA group were significantly reversed (P<0.05 or P<0.01). CONCLUSIONS HBF can prevent intrahepatic cholestatic liver injury in rats, and the effects may be related to the activation of FXR signaling pathway and the reduction of inflammation and oxidative stress.
ABSTRACT
Objective:To investigate the risk factors associated with mortality in patients with severe traumatic liver injury (TLI) and to establish and validate an early prediction model for mortality.Methods:A retrospective cohort study was conducted to analyze the clinical data of 273 patients with severe TLI admitted to the ICU from the medical information mart for the intensive care-IV (MIMIC-IV) database. The cohort consisted of 176 males and 97 females, with age ranging from 18 to 83 years [35.6 years(25.7,57.5)years]. The patients were divided into two groups based on in-hospital mortality: the survival group (253 patients, 92.7%) and the death group (20 patients, 7.3%). The two groups were compared with regards to gender, age, cause and type of injury, treatment method, massive blood transfusion, comorbidities as well as vital signs and laboratory tests measured within 24 hours of ICU admission. Univariate analysis was used to screen for risk factors associated with mortality in severe TLI patients. Independent risk factors for mortality were determined using multivariate Logistic regression analysis. Lasso regression was used to screen for predictors of mortality, and a nomogram prognostic model was then established through a multivariate Logistic regression analysis. The area under the receiver operating characteristic (ROC) curve (AUC) was used to evaluate the discrimination of the model, while the Hosmer-Lemeshow goodness-of-fit test and calibration curve were used to evaluate the calibration of the model. The model′s clinical applicability was evaluated through decision curve analysis (DCA). Internal validation was performed by the 200 Bootstrap samples, and external validation was performed by using 163 patients with severe TLI from the emergency ICU collaborative research database (eICU-CRD). Finally, the predictive efficacy of the nomogram model was compared to other trauma or severity scores.Results:Univariate analysis showed that the age, cause of injury, massive blood transfusion, chronic liver disease and laboratory tests measured within 24 hours of ICU admission, including temperature, systolic blood pressure, diastolic blood pressure, mean arterial pressure, shock index, platelets, red blood cell distribution width (RDW), mean red blood cell hemoglobin concentration (MCHC), blood glucose, blood urea nitrogen, creatinine, anion gap, bicarbonate, prothrombin time (PT), activated partial thromboplastin time (APTT) and international normalized ratio (INR) were associated with the mortality of severe TLI patients ( P<0.05 or 0.01). Multivariate Logistic regression analysis revealed that age ( OR=1.08, 95% CI 1.03, 1.12, P<0.01), body temperature <36 ℃ ( OR=8.00, 95% CI 2.17, 29.53, P<0.01), shock index ( OR=9.59, 95% CI 1.76, 52.18, P<0.01) and anion gap ( OR=1.32, 95% CI 1.15, 1.53, P<0.01) were significantly associated with mortality in severe TLI patients. Lasso regression analysis selected 7 predictors, including age, body temperature<36 ℃, shock index, anion gap, chronic liver disease, creatinine and APTT. Based on these 7 predictors, a nomogram prediction model was developed. The AUC of the nomogram for predicting mortality was 0.96 (95% CI 0.94, 0.99), and the Hosmer-Lemeshow goodness-of-fit test indicated a good fit ( P>0.05). The calibration curve demonstrated excellent consistency between the predicted and actual probabilities, and DCA demonstrated that the model had good clinical net benefit at all risk threshold probability ranges. Internal validation confirmed the stability of the model ( AUC=0.96, 95% CI 0.92, 0.98), and external validation demonstrated good generalization ability ( AUC=0.95, 95% CI 0.91, 0.98). Moreover, the nomogram exhibited superior predictive efficacy compared with injury severity score (ISS), revised trauma score (RTS), trauma injury severity score (TRISS), sequential organ failure score (SOFA), acute physiological score III (APS III), Logistic organ dysfunction score (LODS), Oxford acute severity of illness score (OASIS) and simplified acute physiological score II (SAPS II). Conclusions:Age, body temperature <36 ℃, shock index and anion gap are independent risk factors for mortality in severe TLI patients. A nomogram prognosis model based on 7 predictors, namely age, body temperature <36 ℃, shock index, anion gap, chronic liver disease, creatinine and APTT exhibits good predictive efficacy and robustness, and is contributive to accurately assess the risk of mortality in severe TLI patients at an early stage.
ABSTRACT
Objective To investigate the risk factors for covert hepatic encephalopathy (CHE) in patients with liver cirrhosis and their influence on prognosis. Methods A total of 416 patients with liver cirrhosis who were hospitalized in a grade A tertiary hospital in Chongqing from September 2019 to June 2020 were enrolled in the study, and according to the presence or absence of CHE, they were divided into CHE group with 212 patients and non-CHE group with 204 patients. Clinical data and laboratory examination results were collected, and follow-up was performed for 6 months. The t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test, the continuous correction chi-square test, and the Mann-Whitney U test were used for comparison of categorical data between groups. Univariate and multivariate logistic regression analyses were used to analyze the risk factors for CHE. Results The incidence rate of CHE was 51%. The univariate analysis showed that age, course of disease, the medical history of hepatic encephalopathy (HE), infection, ascites, electrolyte disturbance, hepatorenal syndrome, Child-Pugh class, prothrombin time, total bilirubin, creatinine, platelet, prothrombin activity, albumin, and Model for End-stage Liver Disease (MELD) score were the influencing factors for CHE (all P < 0.05). The multivariate logistic regression analysis showed that the medical history of HE ( OR =10.848, 95% CI : 4.971-23.674, P < 0.05), transjugular intrahepatic portosystemic shunt (TIPS) ( OR =4.334, 95% CI : 1.203-15.621, P < 0.05), Child-Pugh class ( OR =4.968, 95% CI : 1.299-18.992, P < 0.05), and MELD score ( OR =1.253, 95% CI : 1.161-1.352, P < 0.05) were independent predictive factors for CHE ( P < 0.05). The follow-up study showed that CHE had an effect on the short-or medium-term readmission, HE, and death of patients (all P < 0.05). Conclusion CHE has a relatively high incidence rate and greatly affects the prognosis of patients with liver cirrhosis. The development of CHE should be taken seriously in patients with a past history of HE, a history of TIPS, Child-Pugh class C liver function, and a high MELD score, and identification, screening, and intervention should be performed as early as possible to improve the prognosis of patients with liver cirrhosis.

Hepatocellular carcinoma (HCC) often has an insidious onset, and most patients are in the advanced stage and have lost the best opportunity for treatment at the time of diagnosis, resulting in a poor prognosis. As a multifunctional transcription factor, Yin Yang 1 (YY1) regulates the transcription of a variety of important genes and plays a key role in various tumors. Previous studies have shown that YY1 affects many biological behaviors such as proliferation, apoptosis, migration, and angiogenesis and is closely associated with drug resistance and poor prognosis of HCC. This article reviews the research advances in the role of YY1 in the development and progression of HCC, so as to provide a theoretical basis for the treatment of HCC.

ABSTRACT
【Objective】 To investigate the effect of ethanol extracts of Siwei Dihuang on the apoptosis of cardiomyocytes and its mechanism. 【Methods】 The experiment set the control group, model group, model group + ethanol extracts of Siwei Dihuang-L group, model group + ethanol extracts of Siwei Dihuang-M group, model group + ethanol extracts of Siwei Dihuang-H group, model group + miR-NC group, model group + miR-26b group model group + ethanol extracts of Siwei Dihuang-M + anti-miR-NC group, and model group + ethanol extracts of Siwei Dihuang-M + anti-miR-26b group. Flow cytometry was used to detect apoptosis; lactate dehydrogenase (LDH) kit, superoxide dismutase (SOD) kit, and malondialdehyde (MDA) kit were used to detect LDH, SOD activity and MDA content, respectively. Real-time quantitative PCR (RT-qPCR) was used to detect miR-26b and MAPK mRNA levels; luciferase report experiment was conducted to detect the targeting relationship between miR-26b and MAPK. 【Results】 Compared with those in control group, the apoptosis rate of the cardiomyocytes of the model group was significantly increased, MDA content and LDH activity were significantly increased, the activity of SOD was significantly decreased, miR-26b expression was significantly decreased, but MAPK mRNA expression was significantly increased (P<0.05). Treatment with low, medium and high concentrations of ethanol extracts of Siwei Dihuang could reduce apoptosis rate, MDA content and LDH activity, increase SOD activity and increase miR-26b expression, and decrease MAPK mRNA expression (P<0.05). Overexpression of miR-26b inhibited high glucose-induced cardiomyocyte apoptosis and oxidative stress. Inhibition of miR-26b reversed the inhibitory effect of ethanol extracts of Siwei Dihuang on H9C2 apoptosis and oxidative stress in high glucose-induced cells. miR-26b targeted and regulated MAPK. 【Conclusion】 Ethanol extracts of Siwei Dihuang can inhibit the apoptosis and oxidative stress of H9C2 cells in high glucose, and its mechanism may be related to the upregulation of miR-26b and MAPK expressions.
ABSTRACT
Objective:To investigate the correlation between inositol level and glycolipid metabolism in gravidas with gestational diabetes mellitus (GDM).Methods:A cross-sectional study was conducted on 80 GDM cases undergoing routine examination at Fujian Provincial Maternity and Children's Hospital from November 2018 to August 2019, who were selected as GDM groups. Another 50 women with uncomplicated pregnancies during the same period were selected as the control group. Blood and urine inositol level and serum glycolipid profiles were compared between the two groups, and their association was analyzed. Independent or paired-sample t test, Mann-Whitney test, Chi-square (or Fisher's exact) test, and Pearson correlation test were performed for statistical analysis. Results:The serum inositol concentration and high-density lipoprotein (HDL) cholesterol in the GDM group were significantly lower [322.1 ng/ml (279.1-364.1 ng/ml) vs 403.8 ng/ml (391.8-425.3 ng/ml), Z=-7.879; 1.8 mmol/L (1.5-2.0 mmol/L) vs 2.0 mmol/L (1.7-2.2 mmol/L), Z=-2.419; both P<0.05], while the concentration of urine inositol, lipoprotein-a (lipo-a), 0 h-, 1 h-, 2 h-oral glucose tolerance test (OGTT) glucose, fasting insulin, and glycosylated hemoglobin (HbA1c) were significantly higher when comparing to the control group [192.2 ng/ml (171.0-219.9 ng/ml) vs 143.8 ng/ml (121.1-158.6 ng/ml), Z=-6.834; 253.2 mg/L (65.0-349.0 mg/L) vs 148.5 mg/L(46.5-159.3 mg/L), Z=-0.187; 5.0 mmol/L (5.1-5.6 mmol/L) vs 4.4 mmol/L (4.2-4.6 mmol/L), Z=-5.547; 10.0 mmol/L (9.1-11.3 mmol/L) vs 7.8 mmol/L (7.0-8.4 mmol/L), Z=-6.987; 8.6 mmol/L(7.6-9.4 mmol/L) and 6.6 mmol/L (5.7-7.1 mmol/L), Z=-7.100; 18.2 mU/L(10.6-25.9 mU/L) vs 11.0 mU/L (6.3-12.7 mU/L), Z=-4.537; 5.4%(4.5%-5.5%) vs 5.1%(4.9%-5.4%), Z=-3.468; all P<0.05]. (2) Serum inositol concentration was negatively correlated with fasting insulin and 0 h-, 1 h-, 2 h- OGTT glucose level ( r=-0.386, -0.416, -0.350 and -0.407, respectively); urinary inositol concentration was positively correlated with 0 h-, 1 h-, 2 h-OGTT glucose levels ( r=0.402, 0.389 and 0.429, respectively) (all P<0.05). Conclusions:Serum inositol concentration was decreased, and urinary inositol excretion was increased in women with GDM. Measurement of changes in inositol levels during the second trimester may be helpful to assess the metabolic status of pregnant women.
ABSTRACT
【Objective】 To investigate the dynamic changes of local and systemic inflammatory responses after high-fat diet feeding of ApoE-/- mice so as to establish the method to assess the recruitment of PKH26-labeled monocytes into atherosclerotic plaque. 【Methods】 ApoE-/- mice that had received a high-fat diet (HFD) for 8 and 16 weeks were assessed for: ① atherosclerotic plaque burden (oil red O staining), ② aortic tissue inflammation (by RT-qPCR to detect aortic inflammatory factors and cells), ③ systemic inflammatory responses (by ELISA to measure plasma proinflammatory cytokine levels and flow cytometry to assess inflammatory cellular profile in the peripheral blood), and ④ recruitment of PKH26 labeled monocytes into atherosclerotic lesions (by confocal microscope). 【Results】 Compared to those in high-fat diet 8 weeks group, ApoE-/- mice in high-fat diet 16 weeks group had more serious atherosclerosis in the whole aorta and aortic root (P<0.01); significantly up-regulated aortic mRNA levels of inflammatory factors CCL2, TNF-α and IL-1β (P<0.01); an increased number of aortic local macrophages (P<0.001); significantly increased protein expression of plasma CCL2 and TNF-α (P<0.01); and the increased percentage of peripheral blood monocytes (P<0.05). Moreover, the number of PKH26 labeled monocytes that migrated to aortic lesions were significantly higher in high-fat diet 16 weeks group (P<0.01). 【Conclusion】 High-fat diet promotes the severity of systemic and local inflammatory responses in ApoE knockout mice, which contributes to the migration of peripheral blood monocytes to atherosclerotic plaque.
ABSTRACT
Objective:To investigate the effects of forced-air warming blankets combined with conventional warming strategies on the quality of postoperative recovery and cognitive recovery in elderly patients undergoing laparoscopic radical resection of colorectal cancer.Methods:This was a prospective, randomized, controlled trial.A total of 70 patients aged 65-75 years, who were classified as American Society of Anesthesiologists(ASA)grade-Ⅱ or Ⅲ, undergoing the laparoscopic radical resection of colorectal cancer under general anesthesia, were enrolled.Patients were randomly divided into two groups: the forced-air warming group(group FAW, n=35)and the conventional warming group(group CW, n=35). The inadvertent perioperative hypothermia(IPH), postoperative shivering, postoperative agitation, anesthesia recovery time and other postoperative complications were compared between the two groups.The post-operative quality of recovery scale(PQRS)was used to evaluate the quality of postoperative recovery and the recovery of cognitive function before and 1, 3, and 7 days after operation.Results:As compared with the group CW, the group FAW showed that the incidences of IPH, postoperative shivering and agitation were decreased(5.7% vs.22.8%, 2.8% vs.28.6%, 5.7% vs.31.4%, χ2=4.200, 10.057 and 7.652, P=0.042, 0.003 and 0.006), and the satisfaction degree of patients was increased at 48 hours after operation( P<0.01). The postoperative wake-up time was prolonged in the group CW as compared with the group FAW( P<0.01). Compared with the group CW, the proportion of patients with excellent overall recovery quality was increased in the group FAW 1 day after surgery( P<0.05). There was no significant difference in general recovery quality and cognitive recovery between the two groups at 3 and 7 days after operation. Conclusions:For elderly patients undergoing laparoscopic radical resection of colorectal cancer, the forced-air warming blanket combined with conventional warming strategies is more helpful to decrease the incidence of IPH, reduce postoperative shivering and improve the overall recovery quality at 1 day after operation, but no significant effect on postoperative recovery of cognitive function is found.

AIM: To observe the mechanism of celecoxib reversal adriamycin resistance in NK/T cell lymphoma cells. METHODS: SNK6 and SNK6/ADR cells were treated with celecoxib of different concentrations (10, 20, 40, 60, 80, 100 μmol/L), the growth inhibition rate of SNK6 and SNK6/ADR were measured by MTT method. The IC
ABSTRACT
Objective:To investigate differentially expressed genes in muscular tissue in Alzheimer's disease mice and normal mice, and to elucidate the role of differentially expressed genes in the pathogenesis of Alzheimer's disease.Methods:Muscle tissues of Alzheimer’s disease mice and normal mice were collected and the second-generation high-throughput RNA transcription sequencing(RNA-seq)technique was used to screen differentially expressed genes.Additionally, Gene Ontology(GO)functional annotation and Kyoto encyclopedia of genes and genomes(KEGG)pathway analysis were conducted.Differences in the expression of candidate genes in muscle tissues between Alzheimer’s mice and normal mice were verified by real-time fluorescence quantitative polymerase chain reaction(qRT-PCR).Results:A total of 4 222 genes in muscles had different expression between Alzheimer's disease mice and normal mice, with 2087 genes highly expressed and 2 135 lowly expressed in muscles of Alzheimer's disease mice.GO analysis showed that significantly up-regulated functional genes were mainly enriched in cellular, single biological, metabolic and catalytic processes and activities.KEGG pathway analysis showed that differentially expressed genes were significantly enriched in signal pathways related to metabolism and inflammation.Results from qRT-PCR showed that the mRNA expression of candidate genes was consistent with the trend of transcriptome sequencing results.Conclusions:Differentially expressed genes and related important regulatory signal pathways were screened at the transcriptome level in muscle tissues of Alzheimer's disease mice and normal mice.The differentially expressed genes are enriched in signal pathways related to metabolism and inflammation in muscle tissues of Alzheimer's disease mice and the findings provide an important basis for further exploration of the pathogenesis of Alzheimer's disease.
ABSTRACT
Objective:To investigate the correlation between concomitant diabetes mellitus and clinical features in patients with COVID-19.Methods:Fifty patients with COVID-19 admitted to the Sixth People′s Hospital of Shenyang were divided into 2 groups with and without diabetes mellitus. Indexes such as hospitalization days, duration of positive virus-PCR result, secondary infection, duration of fever, rate of liver dysfunction, and rate of cardiac injury were compared between 2 groups.Results:The average hospitalization durations of diabetes group and control group were(24.0±6.8) and(18.4±5.9) days, respectively, and the duration of positive virus-PCR testing results were(16.0±4.5) and(12.3±4.4) days respectively, suggesting longer hospital stay and longer time for virus clearance in the diabetes group than those in the control group(both P<0.05). The rates of secondary infection, severe subtype, liver dysfunction and cardiac injury in the diabetes group increased, though without significant difference( P>0.05). Conclusion:Prolonged duration of positive virus-PCR result and average days of hospitalization in patients with COVID-19 may be associated with diabetes mellitus.
