Objective To analyze the evaluation and influencing factors of healthy enterprises in Hubei Province from 2020 to 2023. Methods A total of 351 enterprises participated in the healthy enterprise evaluation in Hubei province were selected as the study subjects using the judgmental sampling method. The differences in evaluation results including scales, industry sector, and ownership type of the enterprises were compared. Results The median and the 25th and 75th percentiles [M (P₂₅, P₇₅)] of the evaluation score among the 351 enterprises was 869 (838, 941) points. The evaluation pass rate was 82.3%. The M(P₂₅, P₇₅) of scores for the management system, health environment, health management and services, health culture, and health outcome review were 183 (174, 192), 190 (181, 198), 340 (321, 376), 133 (122, 142), and 26 (24, 28) points, with the score percentage of 91.5%, 86.4%, 85.0%, 88.7%, and 86.7%, respectively. The deduction rate exceeded 50.0% in six items, which predominantly concentrated within the primary indicator of the health management and services, among the tertiary indicators. The result of multiple linear regression analysis revealed that smaller enterprises had significantly lower evaluation scores (P<0.05), and domestically funded enterprises scored significantly lower than those with investment from Hong Kong, Macao and Taiwan, or foreign investments (all P<0.05). Conclusion Health management and services represent a weak area in healthy enterprise development in Hubei Province. It was suggested to improve policy incentives and support for medium-, small- and micro-sized enterprises, and domestically funded enterprises, to enhance healthy enterprise development levels.

Spermatogenesis is regulated by several Y chromosome-specific genes located in a specific region of the long arm of the Y chromosome, the azoospermia factor region (AZF). AZF microdeletions are the main structural chromosomal abnormalities that cause male infertility. Assisted reproductive technology (ART) has been used to overcome natural fertilization barriers, allowing infertile couples to have children. However, these techniques increase the risk of vertical transmission of genetic defects. Despite widespread awareness of AZF microdeletions, the occurrence of de novo deletions and overexpression, as well as the expansion of AZF microdeletion vertical transmission, remains unknown. This review summarizes the mechanism of AZF microdeletion and the function of the candidate genes in the AZF region and their corresponding clinical phenotypes. Moreover, vertical transmission cases of AZF microdeletions, the impact of vertical inheritance on male fertility, and the prospective direction of research in this field are also outlined.

Aim To study the therapeutic effect of Balanophora polysaccharide(BPS)on gastric ulcer(GU)induced by acetic acid in rats and to investigateits mechanisms. Methods Sixty male SD rats were randomly divided into sham-operated group, GU model group, omeprazole positive group(3.6 mg·kg-1), and low, medium and high dose of BPS treatment groups(100, 200 and 400 mg·kg-1). The GU model group was prepared by acetic acid cautery method, and the morphology and pathological changes of ulcers were observed by visual observation combined with HE staining, and the ulcer area and inhibition rate were measured and calculated; superoxide dismutase(SOD)activity, malondialdehyde(MDA)content and glutathione peroxidase(GSH-PX)activity were measured by enzymatic assay; tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)content were detected by ELISA. The expression levels of epidermal growth factor(EGF)and epidermal growth factor receptor(EGFR)were measured by immunohistochemistry staining and Western blot. Results Compared with the sham-operated group, obvious ulcer damage was seen in the model group. Compared with the model group, the BPS-treated group showed a significant reduction in ulcer area, an increase in SOD and GSH-PX activity and EGF and EGFR expression levels, and a significant decrease in MDA, TNF-α and IL-6 content. Conclusions BPS has a therapeutic effect on GU in rats, and its mechanism may be related to the inhibition of oxidative stress, suppression of inflammatory stimuli and promotion of regenerative repair of gastric mucosa.

OBJECTIVE: To explore the effect of WDSUB1 on dextran sulfate sodium (DSS)-induced inflammatory colon injury in mice and the underlying mechanism. METHODS: Different WDSUB1 siRNA sequences were transfected into mouse fibroblast L929 cells and the optimal sequence was selected by Western blotting. Twelve male C57BL/6 mice were randomized into two groups for injection of siWDSUB1 or siControl via the caudal vein, followed by treatment with 2.5% DSS in drinking water to establish mouse models of DSS- induced colitis (n=6). The expression level of WDSUB1 in the colon tissue of the mice was detected with Western blotting and RT-PCR, the changes in body weight and fecal condition were recorded, and the clinical symptoms of the mice were evaluated. The mRNA expression levels of IL-6, COX-2 and TNF-α and the protein expression of IκBα and P65 in the colon tissues were detected with RT- PCR and Western blotting, respectively. RESULTS: The mRNA and protein expressions of WDSUB1 in the colon tissues were significantly lower in colitis mice with WDSUB1 knock-down than in the control mice. Compared with the control mice, the mice receiving siWDSUB1 injection showed obviously milder weight loss, diarrhea and hematochezia with significantly lower mRNA expressions of COX2, IL-6 and TNFα (P < 0.05) and protein expression of IκBα but without obvious changes in P65 expression in the colon tissue. CONCLUSION WDSUB1 knockdown can alleviate DSS- induced colitis in mice possibly by inhibiting the NF-κB signaling pathway and decreasing the expression of inflammatory factors in the colon tissues.

【Objective】 To explore the clinical efficacy of traditional Chinese medicine(TCM) therapy in patients with transfusion related iron overload diagnosed with chronic aplastic anemia (CAA). 【Methods】 A total of 115 patients with CAA and iron overload who had been admitted to Zhejiang Provincal Hospital of TCM from February 2015 to December 2016 were studied. They were assigned to treatment group(n=69), positive control group(n=16), and negative control group(n=30) according to different treatment plan designed in advance. Patients in the treatment group were treated with TCM of "Bushen Huoxue" recipe once a day, with the formula mixed with astragalus 40 g, rehmannia 12 g, cornus 12 g, deerhorn glue melting by heat 12 g, atractylodes 20 g, radix paeoniae alba 20 g, curculigo orchioides 10 g, herba epimedii 10 g, cistanche 12 g, cassia stem 10 g, dried orange peel 8 g, poria 10, gingembre 6 g, angelica sinensis 20 g, salvia miltiorrhiza 20 g, zedoary 9 g, leonurus 30 g, gromwell 15 g, and prepared liquorice root 6 g. Patients in positive control group were treated with desferrioxamine for more than 8 h per day, 5 to 7 days per week. Patients in negative control group were treated with basic treatment.The serum ferritin (SF) and cytokines of patients of the three groups before and 3 months after therapy were detected according to the blood-stasis of TCM symptom rating scale, and the correlation between the decrease of ferritin after treatment and the improvement of blood stasis syndrome score was analyzed. 【Results】 The level of SF of the treatment group, positive and negative control group before treatment were 1 881.63±1 386.81 vs 6 581.36±5 180.96 vs1 974.25±1 753.06, and were 2 040.14±1 484.27 vs 4 169.18±3 631.64(P<0.05)vs 2 699.80±2 352.34(P<0.05) 3 months after treatment. The treatment was effctive in 16 patients in treatment group, accounted for 23.19%(16/69). The score of blood stasis syndrome of the three groups before and after treatment were 4.26±1.45vs 6.88±1.31 vs 4.17±1.18 and 4.42±1.43 vs 5.00±0.89 vs 4.67±1.51(P<0.01), respectively. The effective rate of improving blood stasis syndrome score in the treatment group was up to 26.09%. The decrease of serum ferritin was positively correlated with the improvement of blood stasis score (P < 0.01). The levels of IL-6 and IL-10 in treatment group were 20.79±14.14 and 56.27±25.54 before treatment, 13.00±6.48 and 41.02±9.93(P<0.05)3 months after treatment, respectively. 【Conclusion】 "Bushen Huoxue" therapy can stabilize the the level of SF and improve the blood stasis syndrome in CAA patients with iron overload.

Objective: To analyze the electrophysiological characteristics and the therapeutic efficacy of irrigated-tip catheter radiofrequency ablation(RFA) without radiation for pregnant women with focal atrial tachycardia(AT) originating from the right atrial appendage (RAA). Methods: Data from 55 women with focal AT, who underwent radiofrequency ablation (RFA) in the First Affiliated Hospital of Zhengzhou University from October 2016 to March 2019, were screened. 2 non-pregnant women with right atrial appendage tachycardia (RAAT) and 4 pregnant women with non-RAAT were excluded. The remaining 49 cases were divided into RAAT during pregnancy group (n=6, including 4 cases of tachycardia-induced cardiomyopathy) and non-pregnant and non-RAAT group (control, n=43). Under the guidance of three-dimensional mapping system, the earliest activation site was identified, RFA with the irrigated catheter without x-ray fluoroscopy was performed in RAAT patients during pregnancy, all patients in control group underwent non-zero-ray ablation. Patients were followed up at 3, 6, 12 months post procedure, and yearly follow up thereafter in outpatient clinic. Electrocardiogram or Holter monitoring was performed during follow up. AT recurrence and surgical complications were recorded during follow up. At 6 months after RFA, echocardiography examination and laboratory examination including N-terminal B-type brain natriuretic peptide measurement were performed in the pregnant patients, delivery results were also recorded in the pregnant patients. The electrophysiological characteristics of RAAT during pregnancy were analyzed, the therapeutic efficacy of RFA was compared between the two groups. Results: This study is a retrospective study. Age ((30.7±6.2)years vs. (57.2±11.7)years), left ventricular ejection fraction ((46.0±12.8)% vs. (60.1±5.9)%), proportions of organic heart disease (0% vs. 58%) were significantly lower in the RAAT patients during pregnancy group than in control group (P<0.05), while proportions of patients with persistent tachycardia (100% vs. 7%), symptoms of chest distress and palpitation (6/6 vs. 49%) and left ventricular ejection farction≤50% (4/6 vs. 9%) were significantly higher in RAAT group than in control group (P<0.05), heart rate was similar between the two groups ((163.7±11.1)beats/minutes vs. (153.7±15.2)beats/minutes, P>0.05). The characteristic P-wave morphology was observed in RAAT patients during pregnancy, i.e, P wave was mostly upright (5/6) in inferior-leads (Ⅱ, Ⅲ, aVF) and in lead I and aVL, deep and wide negative P wave was found in V₁ lead (5/6), and gradually became positive from V₂-V₆. The mean tachycardia cycle length was (361.7±38.5) ms. Three-dimensional mapping showed that the origin points of the 6 RAAT pregnant patients were all scattered in the local region, the local region was ablated accordingly, 2 patients (2/6) received extensive ablation of local areas. Immediate successful rate was similar between the two groups (6/6 vs. 93%). During follow up ((15.3±4.0) months), no complications were observed after RFA, postoperative recurrence rate was similar (1/6 vs. 12%). Uncomplicated delivery was reported in all 6 pregnant RAAT post ablation. Normal cardiac structure and function was observed in the 4 pregnant patients with tachycardia-induced cardiomyopathy post ablation. Compared to pre-ablation phase, reduced left atrial dimension ((30.3±1.3) mm vs. (36.8±6.7) mm, P>0.05), increased left ventricular ejection fraction ((64.0±2.9)% vs. (39.8±10.7)%), reduced left ventricular end-diastolic dimension ((44.8±4.0) mm vs. (60.0±2.9) mm) and reduced N-terminal B-type natriuretic peptide value ((136.2±47.5) ng/L vs. (3 408.4±901.3) ng/L) were observed at 6 months post ablation (P<0.05). Conclusion: The electrophysiological characteristics are suggestive for focal AT originating from RAA during pregnancy. Under the guidance of 3-dimension activation mapping, no fluoroscopic RFA with irrigated-tip catheter is a safe and effective strategy for the treatment of focal RAAT during pregnancy.

Objective: To evaluate the outcomes of myelodysplastic syndromes (MDS) patients who received HLA-matched sibling donor allogeneic peripheral blood stem cell transplantation (MSD-PBSCT) . Methods: The clinical data of 138 MDS patients received MSD-PBSCT from Sep. 2005 to Dec. 2017 were retrospectively analyzed, and the overall survival (OS) rate, disease-free survival (DFS) rate, relapse rate (RR) , non-relapse mortality (NRM) rate and the related risk factors were explored. Results: ①After a median follow-up of 1 050 (range 4 to 4 988) days, the 3-year OS and DFS rates were (66.6±4.1) % and (63.3±4.1) %, respectively. The 3-year cumulative incidence of RR and NRM rates were (13.9±0.1) % and (22.2±0.1) %, respectively. ②Univariate analysis showed that patients with grade Ⅲ-Ⅳ acute graft-versus-host disease (aGVHD) or hematopoietic cell transplantation comorbidity index (HCT-CI) ≥2 points or patients in very high-risk group of the Revised International Prognostic Scoring System (IPSS-R) had significantly decreased OS[ (42.9±13.2) %vs (72.9±4.2) %, χ(2)=8.620, P=0.003; (53.3±7.6) %vs (72.6±4.7) %, χ(2)=6.681, P=0.010; (53.8±6.8) %vs (76.6±6.2) %vs (73.3±7.7) %, χ(2)=6.337, P=0.042]. For MDS patients with excess blasts-2 (MDS-EB2) and acute myeloid leukemia patients derived from MDS (MDS-AML) , pre-transplant chemotherapy or hypomethylating agents (HMA) therapy could not improve the OS rate[ (60.4±7.8) %vs (59.2±9.6) %, χ(2)=0.042, P=0.838]. ③Multivariate analysis indicated that the HCT-CI was an independent risk factor for OS and DFS (P=0.012, HR=2.108, 95%CI 1.174-3.785; P=0.008, HR=2.128, 95%CI 1.219-3.712) . Conclusions: HCT-CI was better than the IPSS-R in predicting the outcomes after transplantation. The occurrence of grade Ⅲ-Ⅳ aGVHD is a poor prognostic factor for OS. For patients of MDS-EB2 and MDS-AML, immediate transplantation was recommended instead of receiving pre-transplant chemotherapy or HMA therapy.

Objective: To evaluate the outcomes of human leukocyte antigen (HLA) matched unrelated donor hematopoietic stem cell transplantation (MUD-HSCT) for adult acute myeloid leukemia (AML) in a single center. Methods: Consecutive adult AML who received MUD-HSCT in our center from January 2008 to April 2017 were studied retrospectively, comparing with patients undergoing matched sibling donor (MSD) -HSCT in the same period. The rates of overall survival (OS) , disease free survival (DFS) , relapse, non-relapse mortality (NRM) , engraftment, acute and chronic graft-versus-host disease (aGVHD and cGVHD) were analyzed. Results: A total of 247 consecutive cases were enrolled, including 46 patients with MUD-HSCT and 201 with MSD-HSCT. All the patients experienced neutrophil engraftment except for one patient who died early in the MSD group, but the median day of engraftment was longer in the MUD group (15.0 vs 14.0, P=0.017) . The accumulative engraftment rate of platelet was comparable between the two groups (93.5%vs 98.0%, P=0.128) . The accumulative incidences of aGVHD (50.0%vs 46.3%, P=0.421) and cGVHD (37.8%vs 43.0%, P=0.581) were not statistically different between the two groups. Compared with the MSD group, the accumulative NRM rate at+36 months after transplantation was significantly higher in the MUD group (22.0%vs 10.4%, P=0.049) , while the relapse rate was not statistical difference (20.5 vs 28.3%, P=0.189) . Both the 3-year OS (61.6%vs 63.3%, P=0.867) and DFS (57.5%vs 61.6%, P=0.760) were comparable between the two groups. Four independent risk factors were confirmed by the multivariate analysis: patient age ≥45 years old, CR2 or NR before transplantation, a history of extramedullary infiltration and the occurrence of grade Ⅲ-Ⅳ aGVHD. No statistical differences were demonstrated in the survival rate between MUD-and MSD-HSCT in different subgroups. Conclusions: The outcomes, such as GVHD, relapse, OS and DFS, were comparable between MUD-and MSD-HSCT for adult AML, but higher incidence of NRM and longer time to neutrophil engraftment in the MUD group. MUD-HSCT is practical and feasible for adult AML who are lack of MSD.

Objective: To compare eficacy and safety of porcine antihuman lymphocyte immunoglobulin (pALG) and rabbit antithymocyte immunoglobulin (rATG) as a part of alternative donor allogeneic hematopoietic stem cell transplantation (AD allo-HSCT) for severe aplastic anemia (SAA). Methods: The clinical data of 46 SAA patients received AD allo-HSCT from January 2006 to November 2016 were retrospectively analyzed. The cohort of patients were divided into two groups based on rATG or pALG as a part of conditioning regimen to compare implantation rate, transplantation related complications and outcome. Results: In rATG group 30 patients achieved ANC reconstitution, 27 patients achieved PLT reconstitution. In pALG group all 16 patients achieved ANC and PLT reconstitutions. There were no significant differences between the two groups in terms of acute graft-versus-host disease (aGVHD) (P=0.475), Ⅲ-Ⅳ grade aGVHD (P=0.876), chronic GVHD (cGVHD) (P=0.309), extensive cGVHD (P=0.687), graft rejection (GR) (P=0.928), bloodstream infection (P=0.443), invasive fungal disease (P=0.829), cytomegalovirus viremia (P=0.095) respectively. Prospective 5-year overall survival (OS) in rATG and pALG groups were (75.1±8.2)% and (53.6±13.3)% with median follow-up of 14(2-102) and 23(4-63) months, respectively (P=0.190). Conclusion: As a part of conditioning regimen, pALG could achieve similar efficacy as rATG, without increasing the incidences of transplantation complications such as GVHD, GR and infection, in the setting of AD allo-HSCT for SAA patients.
