Objective To investigate the expression,synergistic relationship and clinical significance of alcohol de-hydrogenase(ADH1A)and vascular endothelial growth factor-A(VEGFA)in hepatocellular carcinoma(HCC).Methods The expression and correlation of ADH1A and VEGFA in HCC and adjacent normal tissues were ana-lyzed by GEPIA.TCGA and GSEA were used to analyze the pathway of ADH1A in HCC.The clinical and patho-logical data of 84 patients with HCC were collected,and 54 patients with paracancer normal tissue samples were se-lected as controls to analyze the correlation between ADH1A and VEGFA and clinicopathological parameters of HCC.Immunohistochemistry was used to detect the protein expression of ADH1A and VEGFA in cases and con-trols,and the correlation between the expression of ADH1A and VEGFA and the clinical progression and prognosis of patients with HCC was analyzed based on clinical pathological parameters and Kaplan-Meier.Results Bioinfor-matics analysis found that ADH1A was low-expressed in HCC and VEGFA was highly expressed in HCC,and there was a negative correlation between the two(P<0.001);immunohistochemical detection results showed that the expression of ADH1A in HCC tissue was lower than that in normal tissue adjacent to cancer(P<0.01)while the expression rate of VEGFA in HCC tissue was significantly higher than that of normal tissue adjacent to cancer(P<0.01);The recurrence rate of vascular thrombus and HCC patients in HCC group with high expression of ADH1A was lower(P<0.05).The proportion of tumor diameter>5 cm,high TNM stage,microsatellite and G2-G3 dif-ferentiation in HCC tissues in VEGFA high expression group was higher(P<0.05).Kaplan-Meier survival analy-sis showed that patients with high ADH1A expression and low VEGFA expression had a higher five-year survival rate.Conclusion Low expression of ADH1A and high expression of VEGFA in tumor tissues of patients with HCC indicate tumor progression and can be used as one of the prognostic evaluation indicators for patients with HCC.

pancreatic cancer is a common malignant tumor of digestive system, with poor prognosis. About 80% of patients have lost the opportunity of surgical resection when diagnosed. In different treatment schemes, radioactive seed 125I implantation can improve the quality of life of patients with unresectable pancreatic cancer and is expected to improve their survival rate. This article reviews the clinical applications of 125I particle implantation therapy combined with chemotherapy, cryotherapy, intracavitary irradiation, stent placement, radiofrequency ablation, nanoknife, and bypass surgery, in order to better promote its clinical application. However, it is necessary to establish unified dosage standards and regulatory guidelines to make them safer and more widely serve clinical practice.

Background:Doxycycline can be used in the eradication of Helicobacter pylori(Hp)infection,but there is a lack of large sample study to confirm its efficacy and safety.Aims:To explore the efficacy and safety of doxycycline in the eradication of Hp infection.Methods:Literatures on doxycycline and other antibiotics in the eradication of Hp infection were retrieved from CNKI,Wanfang data,VIP,PubMed,Embase,Web of Science,and Cochrane Library from the date of database establishment to October 2023.Meta-analysis was conducted by RevMan 5.3 software.Results:Nineteen literatures including 3 686 patients with Hp infection were enrolled.Both intention-to-treat(ITT)eradication rate(82.51%vs.73.65%;OR=1.72,95%CI:1.42-2.07,P<0.000 01)and per-protocol(PP)eradication rate(88.96%vs.78.06%;OR=1.63,95%CI:1.28-2.06,P<0.000 1)of doxycycline-based regimen were significantly higher than those of non-doxycycline regimens.The adverse reaction rate of doxycycline-based regimen was significantly lower than that of non-doxycycline regimens(8.35%vs.15.01%;OR=0.55,95%CI:0.42-0.71,P<0.000 01).Subgroup analysis showed that Hp eradication rate of doxycycline-based regimen was significantly higher than that of clarithromycin-based regimen(OR=2.67,95%CI:1.84-3.88,P<0.000 01)and levofloxacin-based regimen(OR=2.20,95%CI:1.50-3.22,P<0.000 1),however,no significant difference in Hp eradication rate was found between doxycycline-based regimen and amoxicillin-based regimen(OR=1.09,95%CI:0.78-1.52,P=0.61)and tetracycline-based regimen(OR=0.87,95%CI:0.33-2.26,P=0.77).Conclusions:The eradication rate of doxycycline-based regimen in the eradication of Hp is significantly higher than that of non-doxycycline regimens,and the adverse reaction rate is low,which is worthy of clinical application.

Aim To investigate the relationship between fibrinogen(FIB)and the progression of coronary plaque stenosis rate in patients with type 2 diabetes mellitus(T2DM).Methods Hospitalized T2DM patients who underwent two or more coronary CT angiography(CCTA)examinations in the First Affiliated Hospital of Xi'an Jiaotong U-niversity from January 2015 to December 2020 were included.The subjects were divided into high FIB and low FIB groups according to the median of FIB.The differences in the progression of coronary plaque stenosis rate and other clini-cal characteristics were compared between the two groups,and the relationship between FIB level and the progression of coronary plaque stenosis rate was analyzed by Spearman's correlation analysis and Logistic regression.Results A total of 145 patients were included,73 in the high FIB group and 72 in the low FIB group at baseline,with a median follow-up time of 25(18,40)months between CCTA.The age,proportion of women,and the progression of coronary plaque ste-nosis rate were higher in the high FIB group than those in the low FIB group,and the differences were statistically signifi-cant(P＜0.05).FIB level was positively correlated with the change in coronary plaque stenosis rate(r2=0.308,P＜0.001).Multivariate Logistic regression analysis showed that FIB level was a risk factor for the progression of coronary plaque stenosis rate in patients with T2DM(OR=5.25,95％CI:1.97～14.02,P＜0.001),after adjusting for age,sex and other clinical risk factors.Conclusion High baseline FIB level is an independent risk factor for the progression of coronary plaque stenosis rate in patients with T2DM,and monitoring FIB level is beneficial to cardiovascular risk stratifica-tion in patients with T2DM.

Objective To comparatively observe the value of TIPS combined with catheter-directed thrombolysis and percutaneous transhepatic portal vein catheterization thrombolysis for acute non-cirrhotic non-neoplastic portal vein thrombosis(PVT).Methods Twenty-five patients with acute non-cirrhotic non-neoplastic PVT were retrospectively enrolled and clustered into TIPS group(n=17,underwent TIPS combined with catheter-directed thrombolysis)and liver puncture group(n=8,underwent percutaneous transhepatic portal vein catheterization thrombolysis)according to the access of thrombolysis.The technical success rate,duration of catheter-directed thrombolysis,complications within 7 days,as well as portal vein patency 3 months after treatment,Child-Pugh grading of liver function and occurrence of hepatic encephalopathy(HE)were recorded and compared between groups.Results The technical success rates were both 100%in 2 groups.There was no significant difference of the duration of catheter-directed thrombolysis between groups(P＞0.05).The thrombolytic effect in TIPS group was better than that in liver puncture group(P＜0.05).No significant difference of the occurrence of bleeding within 7 days was found between groups(P＞0.05).After 3 months'follow-up,the degree of portal vein patency in TIPS group was higher than that in liver puncture group(P＜0.05).No significant difference of Child-Pugh grading of liver function nor occurrence of HE was found between groups(both P＞0.05).Conclusion Both TIPS combined with catheter-directed thrombolysis and percutaneous transhepatic portal vein catheterization thrombolysis were effective for treating acute non-cirrhotic non-neoplastic PVT,and the thrombolytic effect of the former was better than the latter.

Objective:To detect the 3′-terminal 2′- O-methylation (2′Ome) modified microRNA-486-5p (miR-486-5p) levels in the serum of patients with coronary heart disease (CHD), and evaluate its clinical application value as a biomarker to assist the diagnosis of CHD. Methods:Seventy patients with CHD diagnosed at the Eastern Theater General Hospital from January 2021 to December 2022 and 60 age-and sex-matched healthy people undergoing health examination during the same period were selected for this retrospective case-control study. The Gensini score was calculated based on coronary angiography results, and patients in the coronary artery disease group was categorized into mild-to-moderate stenosis (40 cases) and severe stenosis subgroups (30 cases); Serum biochemical indexes, miR-486-5p and 2′Ome-miR-486-5p expression levels were compared between the CHD group and the healthy control group; correlation of biochemical indices, Gensini score and serum miR-486-5p and 2′Ome-miR-486-5p levels was assessed by using Spearman correlation analysis; and multifactorial logistic regression was used to analyze the impact of serum miR-486-5p and 2′Ome-miR-486-5p levels on CHD and the degree of coronary artery stenosis; evaluation of the diagnostic value of 2′Ome-miR-486-5p levels on the degree of coronary artery disease and coronary artery stenosis was achieved by using ROC curve.Results:Serum miR-486-5p and 2′Ome-miR-486-5p levels were significantly higher in CHD group than in the healthy control group [0.31 (0.17, 0.84) vs 0.21 (0.11, 0.49), Z=2.055, P<0.05; 2.30 (1.32, 5.40) vs 0.86 (0.55, 1.72), Z=5.840, P<0.05]; Serum 2′Ome-miR-486-5p expression levels were higher in both mild-moderate and severe stenosis subgroups than in healthy controls ( P<0.05), and serum 2′Ome-miR-486-5p levels were higher in the severe stenosis subgroup than in the mild-moderate stenosis subgroup [3.54(1.78, 5.44) vs 1.63(1.25, 4.07), Z=-2.053, P<0.05]. Both serum miR-486-5p and 2′Ome-miR-486-5p levels were positively correlated with the Gensini score ( r=0.277 and 0.479, respectively, P<0.05); multifactorial logistic regression analysis showed that serum 2′Ome-miR-486-5p level was an independent influence factor of the degree of coronary stenosis after adjustig for the effects of confounding factors such as age and sex ( OR=1.025, 95% CI 1.002-1.049, P<0.05). ROC curve analysis showed that the area under the ROC curve of serum 2′Ome-miR-486-5p levels for the diagnosis of CHD patients, mild to moderate and severe stenosis were 0.798, 0.752 and 0.859, with sensitivities of 91.4%, 92.5%, and 73.3%, and specificities of 56.7%, 51.7% and 81.7%, respectively, at the optimal cut-off (0.912, 0.863, 2.209). Conclusion:Serum 2′Ome-miR-486-5p level is increased in CHD patients and is an independent predictor of the severity of coronary artery stenosis, which can be used as a biomarker for the diagnosis of patients with CHD.

Objective:To explore the association between serum high density lipoprotein subtype 3 cholesterol (HDL3-C) levels and the severity and in-stent restenosis of patients with coronary artery disease.Methods:124 patients with coronary artery diseases and 62 healthy controls were included in this clinical case-control retrospective study. Participants were hospitalized from November 2020 to November 2021 at Jinling Hospital, Medical School of Nanjing University were enrolled. Patients with coronary artery disease were as follows: 28 patients with acute coronary syndrome and 96 patients with stable coronary heart disease. Serum HDL3-C levels as well as total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) levels were determined. According to the coronary artery angiography results of all patients at the time of admission, Gensini scores were calculated and patients were divided into in-stent restenosis group ( n=22), no in-stent stenosis group ( n=23) and non-stent implantation group ( n=79). The correlation between HDL3-C levels and other parameters was analyzed by Pearson or Spearman correlation analyses. Multivariate Logistic regression analyses were used to determine the impact of HDL3-C on the in-stent restenosis of coronary artery diseases. Results:Compared with controls, serum levels of HDL3-C and HDL-C were significantly decreased in patients with coronary artery diseases (all P<0.05). There was a significantly negative correlation between HDL3-C levels and Gensini scores ( r=-0.201, P=0.043). Among patients with coronary artery disease, serum levels of HDL3C, TC and TG in the in-stent restenosis group were significantly lower than in no in-stent stenosis group as well as than in the non-stent implantation group (all P<0.05). Multivariate Logistic regression analyses showed that after adjusting for age, sex, lipid-lowering drugs and TC, TG, LDLC parameters, HDL3-C ( OR=0.885, 95% CI 0.791-0.990, P=0.033) and HDL-C ( OR=0.018, 95% CI 0.001-0.426, P=0.013) levels were both independently associated with the occurrence of coronary artery disease; only HDL3-C levels (no in-stent stenosis group as the reference: OR=0.833, 95% CI 0.698-0.994, P=0.042; non-stent implantation group as the reference: OR=0.812, 95% CI 0.685-0.963, P=0.017) were independently associated with the presence of in-stent restenosis ( P<0.05). Conclusions:Serum HDL3-C levels are decreased in patients with coronary artery disease, especially in patients with in-stent restenosis. HDL3-C levels are associated with the severity of coronary artery lesions and the presence of in-stent restenosis of coronary arteries.

ObjectiveTo observe the effect of Jiaji electroacupuncture combined with neurodynamic mobilization on nerve conduction velocity and the expression of Netrin-1, Slit2 and Rho GTPases after sciatic nerve injury in rabbits. MethodsA total of 216 New Zealand rabbits were randomly divided into nomal control group (NC), vector virus group (VV), Jiaji electroacupuncture combined with neurodynamic mobilization group (EN), Netrin-1 group (N1), Slit2 group (S2) and N1+S2 group. Each group was divided into three subgroups according to the postoperative treatment time points (one, two and four weeks), with twelve rabbits in each subgroup. The rabbit model of Sunderland Ⅲ degree injury of the left sciatic nerve was established by clamping method. There was no intervention in NC, and virus was injected during the preparation of the model. Jiaji electroacupuncture and neurodynamic mobilization were administrated three days after operation in EN group. Nerve conduction velocity of sciatic nerve was measured with electromyography. The sciatic nerve and L_4-6 spinal cords were obtained, the expression of Netrin-1 and Slit2 mRNA were detected real-time quantitative polymerase chain reaction and immunofluorescence double staining, and the expression of Rac1, Cdc42 and RhoA protein were observed via Western blotting. ResultsOne, two and four weeks after modeling, the nerve conduction velocity was more in EN group and N1+S2 group than in N1 group and S2 group (P < 0.05); the Netrin-1 and Slit2 mRNA expression were higher in the EN group and N1+S2 group than in the VV group and NC group (P < 0.05); the protein expression of Rac1 and Cdc42 were higher, and the protein expression of RhoA was lower in EN group and N1+S2 group than in N1 group, S2 group and VV group (P < 0.05). ConclusionJiaji electroacupuncture combined with nerve mobilization may promote the axonal regeneration by regulating the expression of Netrin-1 and Slit2, adjusting the imbalance of Rho GTPases enzyme system, and then promoting cytoskeleton reorganization and peripheral nerve regeneration after injury.

The purpose of this study was to evaluate the effect of dicalcium phosphate dihydrate (DCPD) on the biocompatibility of mineral trioxide aggregate (MTA). DCPD was added to MTA (OrthoMTA) to suppress the increase in pH of MTA during hardening, and the change of pH, cytotoxicity, and subcutaneous inflammation reactions in mouse model were observed. The pH of OrthoMTA and DCPD-OrthoMTA at 1st day in phosphate-buffered saline was 12.5 and 12.8, respectively. At 19th day, the pH was 11.6 (OrthoMTA) and 8.8 (DCPD-OrthoMTA). Cytotoxicity of DCPD-OrthoMTA extract was lesser than that of OrthoMTA at high concentration (above 50%) (p<0.05). No significant differences appeared in subcutaneous inflammatory reactions among ProRoot MTA, OrthoMTA and DCPD-OrthoMTA. Therefore, it is likely that there is no apparent relationship between the cytotoxicity and subcutaneous inflammation in our experimental conditions.
