RESUMO
Objective:To provide reference for improving the provincial Internet plus medical service medical insurance payment policy in China.Methods:From three dimensions of policy tools,participants and policy placement,the distribution characteristics of the Internet plus medical service and medical insurance payment related policies that have been issued in 31 provinces of China were analyzed.A total of 58 policy documents were collected,forming 1585 text items.Results:A total of 597 text items were selected for policy tools(X dimension),with supply based,demand based,and environmental based policy items accounting for 20.6%,16.6%,and 62.8%,respectively.A total of 574 text items were selected for the participating entities(Y-dimension),and 414 text items were selected for the policy placement(Z-dimension).Conclusion:There is a structural imbalance in policy tools,and complementarity and coordination should be enhanced.There are significant differences in the application of policy tools among participating entities,and the division of labor and collaboration among participating entities should be deepened.The practicality of policy implementation is not strong,and close connections between links should be strengthened.The distribution of policies among regions is not balanced enough,and policy design should be optimized according to local conditions.
RESUMO
Objective:To investigate COVID-19 vaccination status and relevant adverse reactions in patients with psoriasis treated with biological agents, and to explore the effect of COVID-19 vaccination on psoriatic lesions.Methods:Clinical data were collected from 572 psoriasis patients aged 18 - 60 years, who were registered in the management system of psoriasis patients treated with biological agents in the University of Hong Kong-Shenzhen Hospital from May 2019 to June 2021. The COVID-19 vaccination status was investigated by telephone interviews, and the vaccination-related information was obtained by fixed healthcare workers during a fixed time period according to a predesigned questionnaire. Measurement data were compared between two groups by using t test, and enumeration data were compared by using chi-square test or Fisher′s exact test. Results:The COVID-19 vaccination coverage rate was 43.13% (226 cases) among the 524 patients who completed the telephone interview, and was significantly lower in the biological agent treatment group (30.79%, 105/341) than in the traditional drug treatment group (66.12%, 121/183; χ2 = 60.60, P < 0.001) . The main reason for not being vaccinated was patients′ fear of vaccine safety (49.66%, 148/298) , followed by doctors′ not recommending (26.51%, 79/298) . In the biological agent treatment group after vaccination, the exacerbation of psoriatic lesions was more common in patients receiving prolonged-interval treatment (42.86%, 6/14) compared with those receiving regular treatment (4.40%, 4/91; Fisher′s exact test, P < 0.001) . Skin lesions were severely aggravated in two patients after COVID-19 vaccination, who ever experienced allergic reactions and whose skin lesions did not completely subside after the treatment with biological agents. Conclusions:The COVID-19 vaccination coverage rate was relatively low in the psoriasis patients treated with biological agents, and no serious adverse reaction was observed after vaccination. Prolonged-interval treatment due to COVID-19 vaccination ran the risk of exacerbation of skin lesions.

RESUMO
Objective: To evaluate the efficacy and safety of HLA-haploidentical hematopoietic stem cell transplantation (allo-HSCT) for hepatitis-related aplastic anemia (HRAA) patients. Methods: Retrospective analysis was performed on hepatitis-associated aplastic anemia patients who received haplo-HSCT at our center between January 2012 and June 2022. October 30, 2022 was the final date of follow-up. Results: This study included 28 HRAA patients receiving allo-HSCT, including 18 males (64.3% ) and 10 females (35.7% ), with a median age of 25.5 (9-44) years. About 17 cases of severe aplastic anemia (SAA), 10 cases of very severe aplastic anemia (VSAA), and 1 case of transfusion-dependent aplastic anemia (TD-NSAA) were identified. Among 28 patients, 15 patients received haplo-HSCT, and 13 received MSD-HSCT. The 2-year overall survival (OS) rate, the 2-year failure-free survival (FFS) rate, the 2-year transplant-related mortality (TRM) rate, the 100-day grade Ⅱ-Ⅳ acute graft-versus-host disease (aGVHD) cumulative incidence rate, and the 2-year chronic graft-versus-host disease (cGVHD) cumulative incidence rate were 81.4%, 81.4% (95% CI 10.5% -20.6% ), 14.6% (95% CI 5.7% -34.3% ), 25.0% (95% CI 12.8% -45.4% ), and 4.2% (95% CI 0.6% -25.4% ), respectively. After transplantation, all patients had no significant liver function damage. Compared with the MSD-HSCT group, only the incidence of cytomegaloviremia was significantly higher in the haplo-HSCT group [60.0% (95% CI 35.2% -84.8% ) vs 7.7% (95% CI 0-22.2% ), P=0.004]. No statistically significant difference in the Epstein-Barr virus was found in the 2-year OS, 2-year FFS, 2-year TRM, and 100-day grade Ⅱ-Ⅳ aGVHD cumulative incidence rates and 2-year cGVHD cumulative incidence rate. Conclusion: Allo-HSCT is safe and effective for HRAA, and haplo-HSCT can be used as a safe and effective alternative for newly diagnosed HRAA patients who cannot obtain HLA-matched sibling donors.

RESUMO
Since the oncolytic herpes simplex virus T-VEC was approved in the United States for the treatment of malignant melanoma in 2015, there has been increasing interests in the oncolytic virus therapy. The oncolytic virus therapy also occupies a certain position in the treatment research process of non-small cell lung cancer(NSCLC). Based on the rapid development of genetic engineering and protein engineering, researchers have designed many recombinant oncolytic viruses targeting various specific sites to further improve their targeting and oncolytic effect in order to alleviate symptoms and even cure NSCLC patients. This review introduces the two major classifications of oncolytic viruses, wild type and gene-edited, and how they achieve tumor lysis by specifically targeting and killing tumor cells. We focus on the research progress of oncolytic virus applied alone to treat NSCLC, or combined with chemotherapy, immunotherapies such as chimeric antigen receptor (CAR)-T cell therapy, immune checkpoint inhibitors and other current hot research to treat NSCLC. At the same time, we summarize and discuss the issue of targeted transport, which is of high concern in the academic field of oncolytic virus therapy, and point out that the use of extracellular vesicles as drug carriers has a good potential for development. Finally, we analyze the existing problems and future application prospects in the context of existing basic and clinical studies, to expend new approaches for the treatment of NSCLC, so that it is no longer limited to traditional therapies.
RESUMO
OBJECTIVE@#To investigate the efficacy of Bushen Huoxue Fang (BSHXF, a traditional Chinese medicine formula) for improving recurrent spontaneous abortion (RSA) in mice and the role of tyrosine kinase (JAK2) and transcriptional activator (STAT3) signaling pathway in its therapeutic mechanism.@*METHODS@#Female CBA/J mice were caged with male DBA/2 mice to establish RSA mouse models, which were randomly divided into model group, dydrogesterone group and BSHXF group, with the female mice caged with male BALB/c mice as the control group (n=6). From the first day of pregnancy, the mice were subjected to daily intragastric administration of BSHXF, dydrogesterone, or distilled water (in control and model groups) for 12 days. After the treatments, serum levels of antithrombin III (AT-III), activated protein C (APC), tissue plasminogen activator (t-PA), progesterone, human chorionic gonadotropin (HCG), and estradiol (E2) were detected in each group using ELISA. HE staining was used to observe the morphological changes of the endometrium of the mice. Western blotting was performed to determine the expressions of p-JAK2, p-Stat3 and Bcl-2 in the placenta of the mice.@*RESULTS@#Compared with the control mice, the mouse models of RSA showed a significantly increased embryo loss rate with decreased serum levels of AT-III, T-PA, progesterone, APC and HCG, increased placental expressions of p-JAK2, p-STAT3 and Bax, and decreased expression of Bcl-2 (P < 0.05). Treatments with BSHXF and dydrogesterone both increased serum levels of AT-III, t-PA and HCG in the mouse models; Serum APC level was significantly reduced in BSHXF group and serum progesterone level was significantly increased in dydrogesterone group (P < 0.05).@*CONCLUSION@#BSHXF can improve the prethrombotic state and inhibit cell apoptosis by downregulating the JAK2/STAT3 pathway to increase the pregnancy rate in mouse models of RSA.

Objective: To investigate the early effect and safety of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with a 10-day decitabine-containing conditioning regimen in the treatment of acute myeloid leukemia (AML) /myelodysplastic syndrome (MDS) . Methods: From April 2021 to May 2022, 31 AML/MDS patients who received allo-HSCT with a 10-day decitabine-containing conditioning regimen were analyzed. Results: AML (n=10), MDS-AML (n=6), CMML-AML (n=1), and MDS (n=14) were identified in 31 patients, 16 males, and 15 females, with a median age of 41 (20-55) yr. Neutrophils and platelets were successfully implanted in 31 patients (100%), with a median implantation duration of 12 (9-30) and 14 (9-42) days, respectively. During the preconditioning period, 16 patients (51.6%) developed oral mucositis, with 15 cases of Ⅰ/Ⅱ grade (48.4%) and one case of Ⅲ grade (3.2%). After transplantation, 13 patients (41.9%) developed CMV viremia, six patients (19.4%) developed hemorrhagic cystitis, and four patients (12.9%) developed a local infection. The median time of acute graft versus host disease (aGVHD) following transplantation was 33 (12-111) days. The cumulative incidence of aGVHD and Ⅲ/Ⅳ grade aGVHD was 41.9% (95% CI 26.9%-61.0%) and 22.9% (95% CI 13.5%-47.5%), respectively. There was no severe cGVHD, and mild and moderate chronic GVHD (cGVHD) incidence was 23.5% (95% CI 12.1%-43.6%). As of November 30, 2022, only one of the 31 patients had relapsed, with a 1-yr cumulative relapse rate (CIR) of 3.2% (95% CI 0.5%-20.7%). There was only one relapse patient death and no non-relapse deaths. The 1-yr overall survival (OS) and disease-free survival (DFS) rates were 92.9% (95% CI 80.3%-100%) and 96.8% (95% CI 90.8%-100%), respectively. Conclusions: A 10-day decitabine-containing conditioning regimen for allo-HSCT reduced relapse and was safe and feasible in treating AML/MDS.

Objective: To systematically review the status and factors influencing presenteeism among clinical nurses. Methods: In December 2021, CNKI, CBM, Wanfang, VIP, Web of Science, PubMed, Embase, The Cochrane Library, CINAHL, PsyclNFO and other databases were electronically searched to cross sectional studies on the current situation and factors influencing the occurrence of presenteeism among clinical nurses. The search terms mainly included presenteeism, sick at work, Stanford Presenteeism Scale, nurse, level, risk factor, influence, et al. And the search time was from the establishment of the database to November 30, 2021. Literature screening, data extraction and evaluation of the risk of bias in the included literature were done independently by two researchers, and meta-analysis was performed using Stata 15.1 software. Results: A total of 29 studies involving 13 535 clinical nurses were included.The results of the meta-analysis showed that the score of presenteeism was 17.99 [95% CI (17.02-18.95), P =0.000]. Subgroup analysis showed that presenteeism scores were higher in articles published before 2020 (ES=19.28, 95%CI: 18.41-20.15, P=0.000) and in the group of nurses aged 36 to 40 years (ES=19.27, 95%CI: 17.35~21.19, P=0.000), female (ES= 17.04, 95%CI: 14.70-19.39, P=0.000), secondary school education (ES=21.01, 95%CI: 17.76-24.26, P= 0.007), married (ES=17.49, 95%CI: 15.13-19.85, P=0.000), working for 5 to 10 years (ES=17.78, 95%CI: 16.54-19.02, P=0.000), contract (ES=17.05, 95%CI: 15.23-18.87, P=0.000), working in pediatrics (ES= 16.65, 95% CI: 15.31-17.99, P=0.000) and European region (ES =21.21, 95% CI: 20.50-21.93, P=0.000) . Conclusion: Current evidence suggests that clinical nurses are at high risk of presenteeism, which is affected by variety of factors. The managers should pay attention to the physical and mental health of nurses, identify high-risk factors as early as possible and take measures to reduce the occurrence of presenteeism and improve the quality of nursing.

Objective: To summarize the clinical characteristics of patients with cleidocranial dysplasia (CCD) and analyze their treatment methods. Methods: From January 2000 to December 2020, patients with CCD who completed comprehensive treatment in the Department of Orthodontics and the First Dental Clinic, School and Hospital of Stomatology, China Medical University were retrospectively analyzed. A total of 14 CCD patients [7 males and 7 females, aged (16.1±4.5) years] were collected. There were 153 impacted permanent teeth in this study. In addition to the teeth that needed to be extracted due to special conditions, 147 impacted teeth were pulled into the dentition using closed traction. Patients were divided into adolescent group (≥12 years and<18 years, 10 patients) and adult group (≥18 years, 4 patients). Failure rate of traction was compared between the two groups. Factors affecting the success rate of closed traction such as vertical position of teeth (high, middle and low) and horizontal position of the teeth (palatal, median and buccal) were analyzed. Results: The incidence of maxillary impacted teeth [69.3% (97/140)] was higher than that of mandibular impacted teeth [40% (56/140)]. The difference was statistically significant (χ2=24.22, P<0.001). The supernumerary teeth were mainly located in the premolar area 61.4% (21/44), and most of them were in the palatal region of the permanent teeth 95.5% (42/44). They were generally located at the same height or the occlusal side of the corresponding permanent teeth. The success rate of closed traction was 93.9% (138/147). The success rate in the adolescent group [98.2% (108/110)] was higher than that in the adult group [81.1% (30/37)], and the difference was significant (χ2=14.09, P<0.05). Failure after closed traction of 9 teeth was found totally, including 7 second premolars. The success rate of traction in impacted second premolars at different vertical (χ2=11.44, P<0.05) and horizontal (χ2=9.71, P<0.05) positions in alveolar bone was different significantlly. The success rates of the second premolars were high (15/16), middle (12/13), low (2/7), and lingual palatine (10/17), median (19/19), lip-buccal (0/0), respectively. Conclusions: The closed traction of impacted teeth in patients with CCD was effective, and the age was the main variable affecting the outcome. The success rate of traction in impacted second premolars located in low position vertically or in palatal position was low, which required close observation during treatment.

OBJECTIVE@#To identify traditional Chinese drugs that contain active ingredients for treatment of myocardial infarction (MI) and explore their therapeutic mechanisms using network pharmacology and molecular docking technology.@*METHODS@#The TCMSP database was used for screening the traditional Chinese drugs containing active ingredients for treating MI, and the related targets of MI and the candidate drugs were obtained from Genecards, OMIM, PharmGkb and PharmMapper databases. The common target network of the drug targets and disease targets was established using Venny2.1.0 software. GO and KEGG signal pathway enrichment analysis of the common targets was performed, and the protein-protein interaction (PPI) network was constructed for the targets. The targets in the PPI network were analyzed to identify the key targets, for which GO and KEGG pathway enrichment analyses were performed. Molecular docking was performed for the candidate ingredients and the key targets, and a total score ≥6 was used as the criteria for screening the therapeutic ingredients and their docking binding with key targets was verified. A human umbilical vein endothelial cell (HUVEC) model of oxygen-glucose deprivation (OGD) was used to validate the candidate ingredients and the key therapeutic targets for MI by Western blotting.@*RESULTS@#Our analysis identified Salvia miltiorrhiza and Dalbergiae odoriferae as the candidate drugs rich in active ingredients for treatment of MI. These ingredients involved 16 key therapeutic targets for MI, which participated in such biological processes as inflammatory response, angiogenesis, energy metabolism and oxidative stress and the pathways including HIF-1, VEGF, and TNF pathways. Sclareol and PTGS2 in Salvia miltiorrhiza and formononetin and KDR in Dalbergiae odoriferae all had high docking total scores. Western blotting showed that at medium and high doses, sclareol significantly inhibited PTGS2 expression and formononetin promoted KDR expressions in the cell models in a dose-dependent manner (P < 0.05).@*CONCLUSION@#Both Salvia miltiorrhiza and Dalbergiae odoriferae have good therapeutic effects on MI. Sclareol in Salvia miltiorrhiza and formononetin in Dalbergiae odoriferae regulate the expressions of KDR and PTGS2, respectively, to modulate the inflammatory response, angiogenesis, oxidative stress and energy metabolism and thus produce myocardial protective effects.

ObjectiveWe aimed to investigate the efficacy and mechanism of Yishen Shengjing Prescription (YSP) in the treatment of oligoasthenospermia in rats. MethodThe oligoasthenospermia rat model was established by injection with cyclophosphamide (35 mg·kg-1·d-1) for 5 consecutive days. Rats were randomly assigned into control group (without treating with cyclophosphamide), model group, low- (YSP-L), medium- (YSP-M), and high- (YSP-H) dose (2.91, 5.83, and 11.66 g·kg-1, respectively) groups, Wuzi Yanzongwan (WYW, 1.03 g·kg-1) group, and L-carnitine (0.17 g·kg-1) group, with 8 rats in each group. After 28 days of drug intervention, the body weight, testicular weight, and testicular index of rats were recorded. The sperm quality in epididymis was detected by computer-assisted sperm analysis (CASA) system. Hematoxylin-eosin (HE) staining was employed for observation of testicular tissue morphology. The levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in testicular tissue were detected by colorimetry. The levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T) in serum were determined by enzyme-linked immunosorbent assay(ELISA). TdT-mediated dUTP nick-end labeling (TUNEL) was employed to detect the apoptosis of testicular cells. The protein levels of B cell lymphoma-2(Bcl-2), Bax, and cleaved Caspase-3 in testicular tissue were detected by Western blot. ResultCompared with the control group, the model group showed decreased body weight, testicular weight and index, sperm concentration and motility (P<0.01) and increased testicular pathological score (P<0.01). Compared with the model group, the YSP-M, YSP-H, WYW, and L-carnitine groups showed increased body weight, testicular weight, testicular index, sperm concentration and motility and decreased testicular pathological score. After modeling, the SOD level decreased (P<0.01) while the MDA content increased (P<0.01) in the testicular tissue. YSP-H, WYW, and L-carnitine reversed the SOD and MDA level changes caused by modeling. Compared with the control group, the model group exhibited declined T level (P<0.01) and increased FSH and LH levels (P<0.01). Compared with the model group, YSP, WYW, and L-carnitine increased the T level (P<0.01) and decreased the LH level (P<0.05, P<0.01). The apoptosis rate of spermatogenic cells in the model group was higher than that in the control group (P<0.01), whereas YSP-M, WYW, and L-carnitine reversed such changes (P<0.01). The model group rats showed decreased expression of Bcl-2(P<0.05) and increased expression of Bax and cleaved Caspase-3 (P<0.05, P<0.01). Compared the model group, YSP-M, YSP-H, WYW, and L-carnitine up-regulated the Bcl-2 expression and down-regulated the cleaved Caspase-3 expression (P<0.05, P<0.01). ConclusionYSP improved the sperm quality of oligoasthenospermia model rats by regulating the antioxidant system and sex hormone levels and inhibiting the apoptosis of spermatogenic cells.
RESUMO
Atopic dermatitis is a chronic, refractory and inflammatory skin disease with the clinical manifestations of severe pruritus and recurrent attacks. It has a high incidence and is closely correlated with other allergic, autoimmune or infectious diseases, which can cause a variety of secondary diseases and mental and psychological disorders, seriously affecting the life quality of patients. Chinese herbal medicines have been used for the prevention and treatment of atopic dermatitis for thousands of years, and many Chinese herbal medicines (including compound prescriptions) effective for this disease have been recorded. These medicines generally have little adverse reactions and the treated patients have low recurrence rate of atopic dermatitis. According to the evidence of modern medicine, the onset of atopic dermatitis is related to the impairment of skin barrier function, abnormal immune response, and abnormal differentiation of mast cells, antigen-presenting cells, and eosinophils. Additionally, it is associated with mental, endocrine, metabolic and other factors. The defect of skin barrier function and the dysfunction of immune system are the main pathogenesis of atopic dermatitis. In recent years, scientists have achieved certain progress in improving skin barrier function with Chinese herbal medicines. This paper systematically summarizes the studies about the application of Chinese herbal medicines in regulating the expression of epidermal proteins, epidermal lipids, aquaporins, tight junction proteins, and antimicrobial peptides in recent 10 years, aiming to clarify the pathological mechanism and provide reference for the clinical research and application of Chinese herbal medicines in the treatment of atopic dermatitis.
