Objective:To investigate the value of serum vascular endothelial growth factors (VEGF), pepsinogen ratio (PGR) combined with magnifying chromoendoscopy in the diagnosis of Epstein-Barr virus associated gastric carcinoma (EBVaGC).Methods:A retrospective case control study was conducted. The clinical data of 314 patients with gastric cancer who were confirmed by pathological examination in Baoji Central Hospital from January 2018 to January 2023 were retrospectively collected. All patients were divided into EBVaGC group (34 cases) and EB virus negative gastric cancer (EBVnGC) group (280 cases) according to the result of EB virus quantitative real time polymerase chain reaction in serum before treatment, while 50 healthy volunteers who underwent the physical examination in the same period were selected as the control group. The level of VEGF was detected by using enzyme-linked immunosorbent assay (ELISA), and serum levels of pepsinogen (PG) Ⅰ and PGⅡ were detected by using fluorescence immunochromatography. PGR was calculated by PGⅠ-to-PGⅡ ratio. Electronic magnification gastroscopy was performed, suspicious lesions were stained and the pathological state of gastric tissues was observed. Taking the pathological results of living tissues as the gold standard, the diagnostic efficacy of each index alone and the combination detection for EBVaGC was calculated. Multivariate logistic regression model was used to analyze the independent risk factors of the incidence of EBVaGC.Results:The age of patients in EBVaGC group, EBVnGC group and the healthy control group was (61±10) years, (63±12) years and (61±12) years, respectively; and there were 28 males (82.4%), 228 males (81.4%) and 41 males (82.0%), respectively. There were no statistically significant differences in age and gender among the 3 groups (all P>0.05). The serum VEGF level and the proportion of positive patients detected by endochromatography in EBVaGC group were higher than those in the EBVnGC group and the healthy control group [VEGF: (253±48) pg/ml vs. (183±38) pg/ml, (92±25) pg/ml; positive proportion: 94.1% (32/34) vs. 77.9% (218/280), 2.0% (1/50)], and the PGR in EBVaGC group was lower than that in EBVnGC group and the healthy control group (2.1±1.0 vs. 3.1±1.1, 14.1±1.9), and the differences were statistically significant (all P<0.05). The sensitivity of serum VEGF in the diagnosis of EBVaGC was higher than that of PGR [73.5% (25/34) vs. 66.9% (22/34)]. The diagnostic specificity of PGR [78.2% (219/280) vs. 69.3% (194/280)] and accuracy [76.8% (241/314) vs. 69.8% (219/314)] were higher than those of VEGF. The sensitivity [85.3% (29/34)], specificity [82.9% (232/280)] and accuracy [83.1% (261/314)] of magnifying chromoendoscopy in the diagnosis of EBVaGC were higher than those of VEGF and PGR. The sensitivity [94.1% (32/34)], specificity [95.7% (268/280)] and accuracy [95.5% (300/314)] of the 3 combined detection were higher than those of single and pairwise detection. Multivariate logistic regression analysis showed that the independent risk factors for the incidence of EBVaGC included alcoholism ( OR = 2.310, 95% CI: 1.243-3.581, P = 0.007), spicy food preference ( OR = 1.516, 95% CI: 1.084-2.142, P = 0.026), irregular diet ( OR = 1.448, 95% CI: 1.013-2.104, P = 0.043), family history of gastric cancer ( OR = 2.732, 95% CI: 1.312-4.894, P = 0.001). Conclusions:Serum VEGF and PGR combined with magnifying chromoendoscopy can improve the diagnostic efficiency of EBVaGC, and developing good eating will be helpful to prevent or slow down the progression of stomach diseases.

Objective:To analyze the detection strategy and basic detection situation of markers of infectious diseases transmitted by transfusion in blood testing laboratories of blood stations in China.Methods:Based on the data of practice comparison working party of Blood Stations in Mainland of China from 2017 to 2021, the data on the testing strategies and the basic detection information of the markers for the transmission of infectious diseases through transfusion in the member laboratories of the practice comparison working party of Blood Stations in Mainland of China from 2017 to 2021 were collected, and the situation of the selection for testing markers, testing strategy and the testing method and other relevant aspects were sorted out and analyzed by charts.Results:The selection of the testing markers was consistent, but HTLV testing item was added in some member laboratories. The detection strategy of using two ELISA reagents and one nucleic acid testing (NAT) reagent simultaneously was adopted in 47 member blood stations; 3) NAT method was dominated by mini pool-NAT in member laboratories. The number of members adopting mini-pools of 8 (MP8)-NAT decreased from 17 in 2017 to 14 in 2021, while the number of members adopting mini-pools of 6 (MP6)-NAT increased from 13 in 2017 to 22 in 2021; Roche NAT system accounted for the largest proportion.Conclusions:In order to ensure blood safety and avoid missing detection, the blood stations still adopt the detection strategy of using two ELISA reagents and one nucleic acid testing (NAT) reagent simultaneously; Meanwhile, in order to increase the NAT positive rate, the proportion of mini pool-NAT mainly decreased year by year despite its dominating role, while the proportion of individual donation-NAT increased year by year; NAT method is transiting from mini-pools of 8 (MP8) to mini-pools of 6 (MP6); The proportion of imported NAT system used in NAT laboratory is relatively large.

Objective:To analyze the correlation between 21-gene recurrence score (RS) and clinicopathological characteristics of patients with Lumina type breast cancer, and to explore its significance in individualized treatment.Methods:The clinicopathological data of 59 patients with surgical resection and pathological diagnosis of Lumina type breast cancer in Shanxi Provincial Cancer Hospital from May 2018 to May 2019 were retrospectively analyzed. Real-time fluorescence quantitative polymerase chain reaction was used to detect the expression of 21 gene and RS was calculated. According to the 21-gene RS, the patients were divided into low recurrence risk group (RS < 18 points), intermediate recurrence risk group (RS 18-31 points) and high recurrence risk group (RS > 31 points). Univariate and multivariate logistic regression analyses were made to evaluate the correlations between different recurrence risk and clinicopathological characteristics of patients and their influence on the choice of adjuvant chemotherapy.Results:Based on the 21-gene RS, 29 patients were in low recurrence risk group, 22 cases were in intermediate recurrence risk group, and 8 cases were in high recurrence risk group. Single-factor analysis showed that age ( P = 0.012), maximum mass diameter ( P = 0.031), histological grade ( P = 0.036), progesterone receptor (PR) level ( P = 0.015), Ki-67 positive index ( P = 0.049) and molecular typing ( P = 0.010) were influencing factors of 21-gene RS recurrence risk. Multivariate logistic regression analysis showed that the age and Ki-67 positive index were negatively correlated with 21-gene RS recurrence risk (both P < 0.05). After grouping according to the 21-gene RS, 17 patients in the intermediate recurrence risk group (according to the traditional postoperative recurrence risk grouping method for breast cancer) were classified as low recurrence risk group, and 4 patients in the low recurrence risk group were classified as intermediate recurrence risk group ( χ2 = 4.535, P = 0.033). After grouping based on 21-gene RS, the number of patients who needed chemotherapy in individualized treatment decreased. Of the 17 cases, 11 cases did not undergo postoperative chemotherapy, and the remaining patients received chemotherapy. The postoperative follow-up period was 11-22 months. As of March 2020, there was no recurrence or disease progress. Conclusion:The 21-gene RS can provide objective basis for the individualized precise treatment and prognosis prediction for patients with early-stage Lumina type breast cancer.

【Objective】 To analyze the HIV-, HCV- and HBV- NAT yield rate in different areas of Henan province, so as to provide the basis for disease prevention and control as well as the establishment of a unified quality control standard for nucleic acid testing(NAT) in the Henan province. 【Methods】 The number and prevalence of NAT yielding samples with isolated infectious virus, namely HIV, HCV and HBV, in 18 blood stations in Henan province from 2017~2019, as well as the trends were analyzed. The NAT quality of each laboratory and each testing system was analyzed according to the ratio of reactive individual donation(ID) results to reactive minipools(MP). 【Results】 The HBV, HCV and HIV ID-NAT yield numbers in 3 501 251 blood donations were HBV 2 606(74/100 000), HCV 21 (0.63/100 000), and HIV 34(1.00/100 000). The HBV ID-NAT yield rate showed an upward trend in the whole province from 2017 to 2019, while the prevalence of HIV and HCV ID-NAT yield didn′t differ significantly during three years. 5 kinds of NAT detection systems were applied in 18 blood centers. among which Ⅰ, Ⅱ, Ⅳ and Ⅴ were triplex detection systems. 2661 ID-reactive samples were implicated in 5 595 MP-reactive samples, with a resolution rate of 47.56%. The resolution rate of triplex NAT system Ⅰ, Ⅱ, Ⅳ and Ⅳ was 39.63%~47.95%, 40.43%~54.36%, 51.61% and 70.00%~45.45%, respectively. An upward trend in triplex NAT resolution rate was observed in 8 laboratories, i. e.B, D, E, F, I, K, L and Q, and an descending trend in A and C. The NAT system Ⅲ, a ID-NAT system, was used only by laboratory C, presenting a NAT-yield rate of 0.19% (282/145 474) and resolution rate of 46.45% (131/282). 【Conclusion】 The majority of NAT-yield of one infectious virus in Henan province is HBV, presenting annual increasing trend. The quality management of NAT laboratories should be strengthened as the divergence was seen in the performance of different NAT laboratories.

【Objective】 To analyze the cause of single-ELISA reactive of four blood screening items in 18 blood stations in Henan, so as to provide the basis for improving the quality of blood screening. 【Methods】 The single-ELISA reactive rate of HBsAg, anti-HCV, HIV Ag/Ab and anti-TP of 18 blood station laboratories in Henan throughout 2019 was calculated, and the causes were analyzed according to different ELISA reagent combinations and gray area settings in each laboratory. 【Results】 The overall single-ELISA reactive rates of HBsAg, anti-HCV, HIV Ag/Ab and anti-TP were 1.740(2 154/1 237 789), 0.564‰(698/1 237 789), 1.421‰(1 759/1 237 789) and 1.561‰(1 932/1 237 789), respectively, showing significant differences by detection items (P <0.05). Person correlation analysis showed that the single-ELISA reactive rate was independent of the gray area settings.but dependent on laboratories and reagent combinations. The single-ELISA reactive rate of HBsAg, anti-HCV, HIV Ag/Ab and anti-TP in D laboratory was the highest and higher than that in other labs using the same reagent.The laboratories with high HBsAg single-ELISA reactive rate were mostly those using a combination of imported reagents and domestic reagents, including the top 6 laboratories. The laboratories with high anti-HCV single-ELISA reactive rate were mostly those using certain domestic reagents. No obvious rules was noticed by single-ELISA reactive for anti-HIV. Laboratories with high anti-TP single-ELISA reactive rate were mostly those using combination 4. 【Conclusion】 The HBsAg single-ELISA reactive rate was the highest in the four blood screening items of blood station laboratories in Henan. The single-ELISA reactive rate is related to the laboratory itself and the reagent manufacturer, suggesting that laboratory quality control should be strengthened and proper reagent combination should be selected to reduce the waste of blood.

One hundred and nine consecutive coronary heart disease (CHD) patients with obstructive sleep apnea (OSA) undergoing percutaneous coronary intervention (PCI) during February 2016 to August 2018 were enrolled in the study. After treatment the quality of sleep was improved in 35 cases (observation group) and was not improved in 74 patients (control group). The basic characteristics, coronary lesions of patients were compared between two groups. Compared with the control group, patients in observation group had significant higher proportion of males [80.0%(28/35) vs. 59.5%(44/74), χ²=4.471, P=0.035], smoking history [85.7% (30/35) vs. 63.5% (47/74), χ²=5.647, P=0.018], lower body mass index [(25.8±3.1) kg/m² vs. (27.4±3.2) kg/m², t=2.461, P=0.033]. Compared with control group, the observation group had lower coronary Gensini score[(35.4±5.7) vs. (38.7±6.5), t=2.571, P=0.011], less number of stent[ (1.4±0.4) vs. (1.6±0.4), t=2.427, P=0.016]. And the lesions were mostly distributed in the right coronary artery in observation group (61.9%, 26/35) (χ²=11.759, P=0.003).Conclusion The improvement of sleep quality by PCI depends on the clinical features and coronary artery lesions of CHD patients with OSA.

Primary sclerosing cholangitis (PSC) is a common autoimmune liver disease,and the diversity of its treatment methods has been hotly discussed by scholars in various countries.As the best treatment,end-stage liver transplantation (LT),due to the related diseases,such as postoperative complications greatly limits its wide application in clinical practice.Early assessment and intervention can reduce the risk of concomitant disease and reduce the occurrence of postoperative complications.In this paper,the status of LT indications,timing and related disease management,postoperative complications and other aspects of PSC patients were reviewed.

To investigate the effect of the jianpi-jiedu formula (JPJD) on the expression of angiogenesis-relevant genes in colon cancer.
 Methods: Crude extract was obtained from JPJD by water extract method. The effect of JPJD crude extract on colon cancer cell proliferation capacity was determined by MTT assays. The IC50 value was calculated by GraphPad Prism5 software. Affymetrix gene expression profiling chip was used to detect significant differences in expressions of genes after JPJD intervention, and pathway enrichment analysis was performed to analyze the differentially expressed genes. Ingenuity Pathway Analysis software was applied to analyze differentially expressed genes relevant to tumor angiogenesis based on mammalian target of rapamycin (mTOR) signaling pathway and then the network diagram was built. Western blot was used to verify the protein levels of key genes related to tumor angiogenesis.
 Results: JPJD crud extract inhibited the proliferation capacity in colon cancer cells. The IC50 values in 24, 48, and 72 hours after treatment were 13.060, 9.646 and 8.448 mg/mL, respectively. The results of chip showed that 218 genes significantly upgraded, and 252 genes significantly downgraded after JPJD treatment. Most of the genes were related to the function of biosynthesis, metabolism, cell apoptosis, antigen extraction, angiogenesis and so on. There were 12 differentially expressed angiogenesis genes. IPA software analysis showed that the JPJD downregulated expression of sphingomyelin phosphodiesterase 3 (SMPD3), VEGF, vascular endothelial growth factor A (VEGFA), integrin subunit alpha 1 (ITGA1), cathepsin B (CTSB), and cathepsin S (CTSS) genes, while upregulated expressions of GAB2 and plasminogen activator, urokinase receptor (PLAUR) genes in the colorectal cancer cell. Western blot results demonstrated that JPJD obviously downregulated expressions of phospho-mTOR (P-mTOR), signal transducer and activator of transcription 3 (STAT3), hypoxia inducible factor-1α (HIF-1α), and VEGF proteins, while obviously upregulated the level of phospho-P53 (P-P53) protein.
 Conclusion: JPJD may inhibit colorectal tumor angiogenesis through regulation of the mTOR-HIF-1α-VEGF signal pathway.
