Objective To investigate the effects of extract from couple medicinals of strengthening healthy qi and eliminating pathogenic qi, i.e.Huangqi(Radix Astragali, astragalus root) and Ezhu (Rhizoma Curcumae, curcumae rhizome), and oxaliplatin(L-OHP)on inhibiting metastasis of CT26 wild-type(CT26.WT)cells, and regulating CXCR3, CCR6 mRNA, and protein expression in rats with colon cancer.Methods Orthotopic transplantation model of BALB/c colon carcinoma was built in mice.L-OHP or L-OHP combined with extract from huangqi and ezhu were given to the mice model.Effects of those medicines on liver metastasis were observed.CXCR3 and CCR6 mRNA expression were measured by using RT-PCR, and CXCR3, CCR6 protein expression was detected with Western Blot.Results L-OHP group and L-OHP combined with Chinese medicinal groups exhibited inhibitive effects on orthotropic tumor growth, and best effect was observed in positive expression (P<0.01).L-OHP combined with TCM can decrease the incidence of liver metastasis (P<0.05).Compared with the control group, mRNA expressions of CXCR3 and CCR6 decreased in the model group and low-dose group (P<0.01).Effects of L-OHP combined with low-dose Chinese medicine were more effective than other groups(P<0.01).Compared with the control group, CXCR3 and CCR6 protein expressions decreased sinificantly in all groups(P<0.05 or P<0.01).Conclusion Mechanism of huangqi, ezhu and oxaliplatin(L-OHP) to inhibit tumor metastasis may relate to downregulation of CXCR3, CCR6 mRNA and protein expression.

database until 2015-01, and all randomized controlled trials (RCT) upon (RVS) pacing and (RVA) pacing in Chinese population were enrolled. According to Cochrane Handbook 5.0.2 quality evaluation criteria, the publications were selected by 2 independent researchers and Meta-analysis was conducted with RevMan5.0 software.
Results: A total of 16 RCT articles including 1199 patients were enrolled in this study. The research was divided into 2 groups: RVS group,n=602 and RVA group,n=597. Meta-analysis indicated that the following indexes in RVS group were better than those in RVA group: the differences between post-and pre-operation for the combination value in LVEF (MD=1.90, 95% CI 0.75-3.05,P=0.001), stroke volume (MD=7.08, 95% CI 2.39-11.76,P=0.003), QRS wave width (MD=29.13, 95% CI 5.71-52.54,P=0.01), LVESV (MD=2.04, 95% CI -4.22 to 8.31,P<0.00001), LVEDV (MD=2.64, 95% CI 1.80-3.49, P<0.00001), BNP (MD=68.00, 95% CI 57.57-78.43,P<0.00001), inter ventricular septum and left ventricular posterior wall motion delay time (SPWMD) (MD=22.68, 95% CI 16.91-28.45,P<0.00001), E/A (MD=0.49, 95% CI 0.41-0.57, P<0.00001), LRVPEI (MD=14.06, 95% CI 12.36-15.75,P<0.00001), resistance of electrode (MD=-67.02, 95% CI -119.96 to -14.08,P=0.01) and pacing threshold (MD=0.09, 95% CI 0.00-0.18,P=0.04). The time of operation in RVS group was longer than that in RVA group, (MD=-11.76, 95% CI -14.69 to -8.82,P<0.00001). The differences between post- and pre-operation in LVEDD, Tei index and X-ray exposure time were similar between 2 groups,P>0.05.

Objective: To analyze the clinical characteristics of hepatic flare and evaluate efficacy of antiviral treatment in pregnant women with chronic HBV infection. Methods: A single-center, open-label, prospective study was conducted, and pregnant women with chronic HBV infection were enrolled. Liver function, HBV serum markers and HBV DNA of pregnant women with chronic HBV infection were reviewed during every 4 to 12 weeks of gestation period. The proportion and clinical characteristics of hepatitis flare during pregnancy were observed. Logistic regression analysis was used to predict hepatic flare in pregnant women with chronic HBV infection. Antiviral therapy with telbivudine (LdT) or tenofovir dipivoxil (TDF) was used to treat hepatic flare during pregnancy. Sequential entecavir (ETV) or TDF was applied after the delivery. Treatment course and drug withdrawal in pregnant women with hepatic flare was the same as those of the general patients with chronic hepatitis B. Liver function, HBV serum markers and HBV DNA were measured in pregnant women with hepatic flare at different time points (4, 12, 24 and 52 weeks). A t-test was used to compare the hepatic flare in pregnant women with and without hepatitis group. HBsAg and HBeAg were used to quantify the receiver operating characteristic (ROC) curve of pregnant women with hepatic flare during pregnancy. Area under the ROC curve was used to calculate the optimal cut-off value corresponding to the maximum sensitivity and specificity of the ROC curve. Results: Of the 220 pregnant women with chronic HBV infection, 55 (25%) had hepatitis flare during pregnancy and received antiviral treatment. Among the 55 women with hepatic flare during gestation, 47 (85.46%) had hepatic flare in the mid-second trimester (12-24 weeks); average peak value of alanine aminotransferase (ALT) was 220.62 U/L, and the average peak value of ALT in 32 cases (58.18%) of pregnant women with hepatic flare was between 2–5 × ULN. HBsAg and HBeAg quantification were significantly lower in pregnant women with hepatic flare during pregnancy than with non-hepatitis (t = -3.745, P < 0.001; t = -2.186, P = 0.030). Multivariate logistic regression analysis showed that pregnant women with HBeAg < 3.065 log10 s/co were 7.576 times more likely to have hepatic flare during pregnancy (95% confidence interval: 3.779-15.190). ALT normalization, undetectable HBV DNA levels, HBeAg loss and HBeAg seroconversion in 55 pregnant women with hepatic flare at 52-week treatment was 100% (55/55), 74.55% (41/55), 47.27% (26/55) and 41.82% (23/55), respectively. HBsAg quantification at 52 weeks was significantly lower than baseline HBsAg quantification (3.32 + 0.37) log₁₀ IU/ml and (3.95 + 0.40) log₁₀ IU/ml; t = 8.465, P < 0.001). Conclusion Hepatic flare often occurs in the second trimester of pregnancy in pregnant women with chronic HBV infection and baseline HBeAg quantification is an independent predictor of hepatic flare. HBeAg seroconversion rate increased at 52 weeks after antiviral therapy.

Objectives: . The necessity to develop a method for prognostication and to identify novel biomarkers for personalized medicine in patients with head and neck squamous cell carcinoma (HNSCC) cannot be overstated. Recently, pathomics, which relies on quantitative analysis of medical imaging, has come to the forefront. CXCL8, an essential inflammatory cytokine, has been shown to correlate with overall survival (OS). This study examined the relationship between CXCL8 mRNA expression and pathomics features and aimed to explore the biological underpinnings of CXCL8. Methods: . Clinical information and transcripts per million mRNA sequencing data were obtained from The Cancer Genome Atlas (TCGA)-HNSCC dataset. We identified correlations between CXCL8 mRNA expression and patient survival rates using a Kaplan-Meier survival curve. A retrospective analysis of 313 samples diagnosed with HNSCC in the TCGA database was conducted. Pathomics features were extracted from hematoxylin and eosin–stained images, and then the minimum redundancy maximum relevance, with recursive feature elimination (mRMR-RFE) method was applied, followed by screening with the logistic regression algorithm. Results: . Kaplan-Meier curves indicated that high expression of CXCL8 was significantly associated with decreased OS. The logistic regression pathomics model incorporated 16 radiomics features identified by the mRMR-RFE method in the training set and demonstrated strong performance in the testing set. Calibration plots showed that the probability of high gene expression predicted by the pathomics model was in good agreement with actual observations, suggesting the model’s high clinical applicability. Conclusion . The pathomics model of CXCL8 mRNA expression serves as an effective tool for predicting prognosis in patients with HNSCC and can aid in clinical decision-making. Elevated levels of CXCL8 expression may lead to reduced DNA damage and are associated with a pro-inflammatory tumor microenvironment, offering a potential therapeutic target.

Objective To observe the effects of Jingning Granule on attention set shifting (AST) in rats with attention deficit hyperactivity disorder (ADHD).Methods Spontaneously hypertensive rats (SHR) were used as rat model of ADHD.Jingning granule (20.25, 10.125, 5.062 5 g/kg), Methylphenidate HCl Extended-release Tablets (Ritalin 6.75 mg/kg) and pediatric Huanglong granule (0.937 5 g/kg) were used as the intervention respectively and administered continuously for 17 days.The number of errors, burrowing times, and error rate in AST were used as the outcome measures.Results Compared with the normal control group, the number of error, error rate, and burrowing times increased in model group in Simple Discrimination (SD) phase, Compound Discrimination (CD) phase, Intra-Dimensional shift (IDS) phase, Reversal Learning (RL) phase, and Extra-Dimensional shift (EDS) phase;compared with the model group, Jingning granule reduced the frequency of error, error rate, and frequency of burrowing, and improved the attention set shifting defects in ADHD rat model.Conclusion ADHD model rats presented defected attention set shifting, and Jingning granule could effectively improve the attention set transfer ability in ADHD model rats.

Objective There is still a lack of effective clinical prognostic factors for predicting outcomes and guiding treatments in extranodal nasal-type NK/T-cell lymphoma (NKTCL).This study was aimed to investigate the clinical features and prognostic role of primary tumor burden (PTB).Methods A total of 1383 patients were recruited from ten hospitals, including 947 stage Ⅰ patients (68.5%), 326 stage Ⅱ patients (23.6%), and 110 stage Ⅲ-IV patients (8.0%).There were 751 patients (54.3%) presenting with high PTB (H-PTB).The Kaplan-Meier method was used to calculate survival rates, and the log-rank test was conducted for survival difference analysis.Meanwhile, a multivariate analysis was performed using the Cox regression model.Results H-PTB was associated with high invasive potential, high frequency of B symptoms, advanced stage, regional lymph node involvement, lactate dehydrogenase elevation, and poor performance status.The patients with H-PTB had significantly lower 5-year overall survival (OS) and progression-free survival (PFS) rates than those with low PTB (L-PTB)(OS:50.2% vs.72.1%, P=0.000;PFS:41.8% vs.62.5, P=0.000).PTB was an independent prognostic factor for both OS (HR=1.851) and PFS (HR=1.755) according to the Cox multivariate analysis.Moreover, H-PTB was associated with significantly lower locoregional control (LRC) in early-stage NKTCL, and the 5-year LRC rate was 71.6% in patients with H-PTB and 84.3% in those with L-PTB (P=0.000).Conclusions H-PTB is associated with multiple adverse clinical features in NKTCL, and it is an independent indicator for poor outcomes and LRC.H-PTB can be used as a reliable indicator for risk stratification and treatment decision.
