Objective:To investigate the prognostic value of serum adenosylhomocysteinase (AHCY) in patients with hepatitis E virus acute liver failure (HEV-ALF).Methods:From 1 January 2017 to 31 December 2022, 100 patients each with HEV-ALF and acute hepatitis E (AHE) from the First Affiliated Hospital of Medical School of Zhejiang University and Affiliated Suzhou Hospital of Nanjing Medical University were included in this case-control study. The HEV-ALF group was 58.56±11.16 years old, including 71 men. The AHE group was 56.04±14.30 years old, including 61 men. All serum samples were obtained before the patient had an acute onset and were obtained without treatment. Firstly, the serum AHCY levels in patients with HEV-ALF and AHE were analyzed by ELISA. Secondly, the serum AHCY levels in HEV-ALF patients with different organ failure and disease condition were compared. According to the number of organ failure, 100 HEV-ALF patients were divided into organ failure number=2 group ( n=58), number=3 group ( n=24) and number>3 groups ( n=18). According to the disease condition, 100 patients were divided into improvement group ( n=49), disease fluctuation group ( n=37), and deterioration group ( n=14). Thirdly, the survival times between the high serum AHCY level group ( n=50) and the low serum AHCY level group ( n=50) were compared. Finally, the independent risk factors to predict mortality using the multivariate Logistic regression analysis, and evaluated the predictive and decision-making abilities of serum AHCY levels were explored using the receiver operating characteristic (ROC) curve and decision curve analysis (DCA). Results:Serum AHCY levels in HEV-ALF patients were significantly higher than those in AHE patients [326.92 (295.37-385.84) pg/ml vs. 222.88 (188.04-246.78) pg/ml, Z=-12.217, P<0.001]. Serum AHCY levels in group 2 were significantly lower than those in group 3 [303.44 (284.40-330.15) pg/ml vs. 335.36 (306.30-385.84) pg/ml, Z=-3.353, P=0.001]. Serum AHCY level in group 3 were significantly lowerthan those in group>3 [335.36 (306.30-385.84) pg/ml vs. 549.89 (423.35-660.22) pg/ml, P<0.001]. The serum AHCY levels in the fluctuation group were lower than those in the deterioration group [322.17 (283.92-423.74) pg/ml vs. 458.26 (374.66, 593.89) pg/ml, Z=-4.016, P=0.009]. The survival time of high serum AHCY level group was significantly lower than that of low serum AHCY level group [23.11 (20.25-25.96) days vs. 29.49 (28.79-30.20) days, Z=-2.596, P<0.001]. The multivariate Logistic regression analysis showed that the levels of serum AHCY and total bilirubin were independent risk factors to predict mortality in HEV-ALF patients [AHCY, OR (95% CI): 1.008 (1.002-1.015), P=0.008; total bilirubin, OR (95% CI): 1.011 (1.005-1.018), P=0.001]. Serum AHCY level predicting the area under the curve (AUC) of 30-day mortality in HEV-ALF patients was 0.912, with a sensitivity of 90.00% and a specificity of 93.75%. DCA results demonstrated that serum AHCY level had good decision-making power for predicting 30-day mortality in HEV-ALF patients. Conclusion:Serum AHCY has an important prognostic value for HEV-ALF patients. Higher serum AHCY levels indicate the worse prognosis of HEV-ALF patients.

Aim To observe the effect of epimedium on the proliferation and stem cell-like character expression of breast cancer cells, and investigate the relationship between the inhibition of stem cell-like character and miR-148a by epimedium, and its molecular mechanism. Methods After treatment with different concentrations of epimedium, cell viability and population dependence were detected by MTT assay and colony formation assay; the breast cancer stem cell-derived mammosphere formation was examined by Mammosphere assay; the expression levels of CD44,ALDH-1, Oct4,BMIl and EpCAM were detected by qPCR; the protein expression levels of EpCAM, SOX4, ZO-1, E-cadherin and vimentin were detected by Western blot; the protein localization of EpCAM was observed by im-munofluorescence assay; the effect of epimedium on migration was detected by wound healing assay. The miR-148a mimic was transfected into MDA-MB-231 cells, and the effects of epimedium on stem-like character expression of transfected MDA-MB-231 cells were observed. Results Epimedium significantly inhibited the proliferation and population dependence of MDA-MB-231 cells (P < 0.05 ), and reduced the breast cancer stem cell-derived mammosphere formation; compared with control group, epimedium significantly decreased mRNA levels of CD44, ALDH-1, Oct4, BMI1 and EpCAM (P <0.05) ,decreased protein contents of EpCAM, SOX4 and Vimentin (P < 0.05 ), up-regulated the protein expression of ZO-1 and e-cadherin ( P <0.05) ,and decreased the migration ability of MDA-MB-231 cells (P < 0.05). Epimedium up-regulated the expression of miR-148a in MDA-MB-231 cells (P <0.01). YYH + miR-148a mimic group significantly inhibited stem-like character expression and EMT process of breast cancer MDA-MB-231 cells compared with control group (P <0.05). Conclusions Epimedium can inhibit the proliferation of MDA-MB-231 cells, which may be related to the up-regulation of miR-148a, decrease of stem-like character expression of breast cancer cells,and inhibition of EMT.

Objective: To analyze the clinical characteristics of children with Burkitt lymphoma (BL) and to summarize the mid-term efficacy of China Net Childhood Lymphoma-mature B-cell lymphoma 2017 (CNCL-B-NHL-2017) regimen. Methods: Clinical features of 436 BL patients who were ≤18 years old and treated with the CNCL-B-NHL-2017 regimen from May 2017 to April 2021 were analyzed retrospectively. Clinical characteristics of patients at disease onset were analyzed and the therapeutic effects of patients with different clinical stages and risk groups were compared. Survival analysis was performed by Kaplan-Meier method, and Cox regression was used to identify the prognostic factors. Results: Among 436 patients, there were 368 (84.4%) males and 68 (15.6%) females, the age of disease onset was 6.0 (4.0, 9.0) years old. According to the St. Jude staging system, there were 4 patients (0.9%) with stage Ⅰ, 30 patients (6.9%) with stage Ⅱ, 217 patients (49.8%) with stage Ⅲ, and 185 patients (42.4%) with stage Ⅳ. All patients were stratified into following risk groups: group A (n=1, 0.2%), group B1 (n=46, 10.6%), group B2 (n=19, 4.4%), group C1 (n=285, 65.4%), group C2 (n=85, 19.5%). Sixty-three patients (14.4%) were treated with chemotherapy only and 373 patients (85.6%) were treated with chemotherapy combined with rituximab. Twenty-one patients (4.8%) suffered from progressive disease, 3 patients (0.7%) relapsed, and 13 patients (3.0%) died of treatment-related complications. The follow-up time of all patients was 24.0 (13.0, 35.0) months, the 2-year event free survival (EFS) rate of all patients was (90.9±1.4) %. The 2-year EFS rates of group A, B1, B2, C1 and C2 were 100.0%, 100.0%, (94.7±5.1) %, (90.7±1.7) % and (85.9±4.0) %, respectively. The 2-year EFS rates was higher in group A, B1, and B2 than those in group C1 (χ²=4.16, P=0.041) and group C2 (χ²=7.21, P=0.007). The 2-year EFS rates of the patients treated with chemotherapy alone and those treated with chemotherapy combined with rituximab were (79.3±5.1)% and (92.9±1.4)% (χ²=14.23, P<0.001) respectively. Multivariate analysis showed that stage Ⅳ (including leukemia stage), serum lactate dehydrogenase (LDH)>4-fold normal value, and with residual tumor in the mid-term evaluation were risk factors for poor prognosis (HR=1.38,1.23,8.52,95%CI 1.05-1.82,1.05-1.43,3.96-18.30). Conclusions: The CNCL-B-NHL-2017 regimen show significant effect in the treatment of pediatric BL. The combination of rituximab improve the efficacy further.

OBJECTIVE: To investigate the effects of nuclear transcription factor-κB(NF-κB)/amide adenine dinucleotide phosphate oxidase 1(NOX1) signaling pathway in tumor necrosis factor-α(TNF-α) induced apoptosis of A549 cells. METHODS: i) A549 cells were stimulated with TNF-α at the concentrations of 0.00, 0.25, 0.50, and 1.00 nmol/L. CCK-8 assay was used to detect the cell viability to screen the optimal stimulating concentration of TNF-α. ii) A549 cells at logarithmic growth stage were randomly divided into four groups, the control group, the TNF-α group, the BAY11-7082(NF-κB inhibitor) group and the TNF-α+BAY11-7082 group. The cells in the control group were not treated. The TNF-α and BAY11-7082 groups were stimulated with 0.50 nmol/L TNF-α and 5 μmol/L BAY11-7082, respectively. The TNF-α+BAY11-7082 group was stimulated by both TNF-α and BAY11-7082. After 24 hours of culture, the cell survival rate was detected by CCK-8 assay. Flow cytometry was used to detect cell apoptotic rate, and Western blotting was used to detect the relative expression of NF-κB(p65) and NOX1 proteins. RESULTS: i) When A549 cells were stimulated with TNF-α at the concentration of 0.50 nmol/L, the cell proliferative activity was reduced and the cell apoptosis was promoted. This concentration was selected as the stimulation dose of TNF-α in subsequent experiments. ii) The survival rate of A549 cells in the TNF-α group decreased(P<0.05), the apoptotic rate and the protein expressions of NF-κB(p65) and NOX1 increased in TNF-α group(all P<0.05) compared with the control group. In BAY11-7082 group, the survival rate and the relative expression of NF-κB(p65) and NOX1 of A549 cells were decreased(all P<0.05), and the apoptotic rate of A549 cells was increased(P<0.05) compared with the control group. A549 cells in TNF-α+BAY11-7082 group changed from a long spindle shape to an irregular one. The cell survival rate increased(P<0.05), the apoptotic rate and the relative expression of NF-κB(p65) and NOX1 decreased(all P<0.05) compared with the TNF-α group. CONCLUSION: NF-κB/NOX1 signaling pathway is involved in A549 cells apoptosis induced by TNF-α.

OBJECTIVE: To observe the clinical effect of high suspension and low incision (HSLI) surgery on mixed haemorrhoids, compared with Milligan-Morgan haemorrhoidectomy. METHODS: A multi-centre, randomized, single-blind, non-inferiority clinical trial was performed. Participants with mixed haemorrhoids from Xiyuan Hospital of China Academy of Chinese Medical Sciences, Beijing Rectum Hospital, Air Force Medical Center of People's Liberation Army of China, and Puyang Hospital of Traditional Chinese Medicine were enrolled from September 2016 to March 2018. By using a blocked randomization scheme, participants were assigned to two groups. The experimental group was treated with HSLI, while the control group was treated with Milligan-Morgan haemorrhoidectomy. The primary outcome was the clinical effect evaluated at 12 weeks after operation. The secondary outcomes included the number of haemorrhoids treated during the operation, pain scores, use of analgesics, postoperative oedema, wound healing, incidence of anal stenosis, anorectal manometry after operation, as well as surgical duration, length of stay and total hospitalization expenses. A safety evaluation was also conducted. RESULTS: In total, 246 eligible participants were enrolled, with 123 cases in each group. There was no significant difference in the clinical effect between the two groups (100.00% vs. 99.19%, P>0.05). Compared with the control group, the number of external haemorrhoids treated during the operation and the pain scores after operation were significantly reduced in the experimental group (P<0.05 or P<0.01); the patient number with wound healing at 2 weeks after operation and the functional length of anal canal at 12 weeks after operation were significantly increased in the experimental group (P<0.05). There was no significant difference in the incidence of anal stenosis, the numbers of patients using analgesics and patients with postoperative oedema between the two groups after operation (P>0.05). The surgical duration and length of stay in the experimental group were significantly longer than those in the control group, and the total hospitalization expense was significantly higher than that in the control group (all P<0.05). No adverse events were reported in either group during the whole trial or follow-up period. CONCLUSION HSLI had the advantages of preserving the skin of anal canal completely, alleviating postsurgical pain and promoting rapid recovery after operation. (Registration No. ChiCTR1900022883).

BACKGROUND: As a bioactive substance, Biodentine has good compressive strength, bonding strength and less micro-leakage. It has been successfully applied to a variety of clinical indications. However, much less is known about whether Biodentine can promote osteogenesis. OBJECTIVE: To explore the effects of Biodentine of different concentrations on proliferation and osteogenesis of MG-63 cells. METHODS: The extracts of Biodentine with different concentration gradients (1, 1/2, 1/4, 1/8, 1/16) were prepared. MG-63 cells were cultured in six groups, with the addition of minimum essential medium (control group) and five concentrations of Biodentine extracts. Cell proliferation was detected by cell counting kit-8 assay at 1, 3, 5 and 7 days, and then the best concentration of Biodentine extract was screened. Another MG-63 cells were cultured in minimum essential medium (blank control group) and Biodentine extract of the optimal concentration (experimental group). The expression of osteogenic factor Runx2 mRNA in MG-63 cells was detected by real-time PCR at 1, 3, 5 and 7 days of culture. Then alizarin red staining was used to observe calcified nodules in MG-63 cells at 10 and 14 days of culture. RESULTS AND CONCLUSION: (1) At 1 and 3 days of culture, the number of viable cells in different concentration groups was similar to that in the control group (P ＞ 0.05). At 5 days of culture, compared with the control group, the number of viable cells in MG-63 cells was significantly lowered in the 1 concentration group, showed no significant changes in the 1/2, 1/4, 1/8 concentration groups (P ＞ 0.05), and was significantly increased in the 1/16 concentration group (P ＜ 0.05). Therefore, the 1/16 concentration of Biodentine extract was used for further experiment. (2) Runx2 mRNA expression of the experimental group at 1, 3, 5 and 7 days of culture was 1.14, 5.29, 1.08 and 2.11 times that of the control group, respectively (all P ＜ 0.05). (3) At 10 days of culture, both the experimental group and blank control group showed no mineralized nodules; at 14 days of culture, mineralized nodules were observed in the two groups, and larger and darker nodules were seen in the experiment group. To conclude, Biodentine at certain concentrations can promote the proliferation and osteogenic activity of human osteosarcoma cell line MG-63.

OBJECTIVETo analyze the relationship between pesticide exposure and adverse pregnancy outcomes in famers.

METHODSA search was conducted to collect the articles about the relationship between pesticide exposure and adverse pregnancy outcomes published worldwide from 1990 to February 2012. Meta-analysis was performed on the collected articles using RevMan 4.2 software.

RESULTSTwelve articles were collected. Compared with the controls, the pesticide-exposed famers showed a combined odds ratio (OR) for spontaneous abortion of 1.52 (95%CI: 1.04 ∼ 2.21; P = 0.03), a combined OR for premature birth of 1.33 (95%CI: 1.09 ∼ 1.61; P = 0.005), a combined OR for dead fetus of 1.22 (95%CI: 1.16 ∼ 1.29; P < 0.01), a combined OR for stillbirth of 1.90 (95%CI: 0.58 ∼ 6.28; P = 0.29), a combined OR for birth defect of 2.02 (95%CI: 0.84 - 4.69; P = 0.12), a combined OR for low birth weight of 1.62 (95%CI: 0.60 ∼ 4.39; P = 0.34), a combined OR for neonatal death of 2.18 (95%CI: 0.54 ∼ 8.88; P = 0.28), and a combined OR for delayed conception of 1.43 (95%CI: 0.93 ∼ 2.18; P = 0.1). Pesticide exposure increased the risks for spontaneous abortion, premature birth, and dead fetus, but was not significantly associated with stillbirth, birth defect, low birth weight, neonatal death, and delayed conception.

CONCLUSIONPesticide exposure can cause adverse pregnancy outcomes in farmers, increasing the risks of spontaneous abortion, premature birth, and dead fetus.

The aim of this study was to investigate the effect of brucine on secretion of TNF-α, IFN-γ, IL-4 and proliferation of T lymphocytes in patients with aplastic anemia (AA), and to explore its mechanism. Peripheral blood T lymphocytes from 10 patients with AA and 10 healthy volunteers were isolated, purified and cultured. T lymphocytes from the patients were divided into 0, 100, 200 and 400 µg/ml brucine-treated groups. T lymphocytes from healthy volunteers were used as control group. After being cultured for 72 hours, the levels of TNF-α, IFN-γ, IL-4 in the supernatant of cultured T lymphocytes from AA patients were detected by ELISA, and the proliferation of T lymphocytes from AA patients was detected by MTT. The results showed that compared with the normal control group, the levels of TNF-α and IFN-γ in the culture supernatant significantly increased, and IL-4 was significantly decreased. The levels of TNF-α and IFN-γ in the culture supernatant of brucine treated groups were lower, and were dependent on the concentration of brucine. However, the levels of IL-4 were found to be not obviously changed. The inhibition rate of T lymphocytes in 100, 200 and 400µg/ml brucine-treated groups were (13.61 ± 4.31)%, (14.28 ± 4.31)% and (15.12 ± 4.56)% respectively, among which the differences were not statistically significant. It is concluded that the brucine can reduce the levels of TNF-α and IFN-γ through inhibiting the proliferation of T lymphocytes in AA patients, which provides experimental basis for therapy of AA patients.
