Threatened abortion is a common disease of obstetrics and gynecology and one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in TCM obstetrics and gynecology， Western medicine obstetrics and gynecology， and pharmacology to deeply discuss the advantages of TCM and integrated Chinese and Western medicine treatment as well as the medication plans for threatened abortion. After discussion， the experts concluded that chromosome， endocrine， and immune abnormalities were the key factors for the occurrence of threatened abortion， and the Qi and blood disorders in thoroughfare and conception vessels were the core pathogenesis. In the treatment of threatened abortion， TCM has advantages in preventing miscarriages， alleviating clinical symptoms and TCM syndromes， relieving anxiety， regulating reproductive endocrine and immune abnormalities， personalized and diversified treatment， enhancing efficiency and reducing toxicity， and preventing the disease before occurrence. The difficulty in diagnosis and treatment of threatened abortion with traditional Chinese and Western medicine lies in identifying the predictors of abortion caused by maternal factors and the treatment of thrombophilia. Recurrent abortion is the breakthrough point of treatment with integrated traditional Chinese and Western medicine. It is urgent to carry out high-quality evidence-based medicine research in the future to improve the modern diagnosis and treatment of threatened abortion with TCM.

Abstract Long noncoding RNA (lncRNA) is closely related to the pathogenesis of cancer,representing a burgeoning field in tumor research in recent years. MAGI2-AS3, a tumor-associated lncRNA, exerts pivotal roles in epigenetics, transcription and post-transcriptional regulation. Studies have suggested that MAGI2-AS3 may be involved in multiple stages of tumor development, and has potential applications for tumor diagnosis, therapy and prognosis. This review summarizes the expression, regulatory mechanism and clinical application value of MAGI2-AS3 in common malignant tumrs, providing the reference for tumor prevention and treatment.

Objective:To analyze the iodine nutrition status of children aged 8 to 10 years in Zhejiang Province from 2016 to 2021.Methods:A multi-stage stratified sampling method was used to select non-residential children aged 8 to 10 years from 90 counties in Zhejiang Province. A total of 114 103 children were included in the study from 2016 to 2021. Direct titration method and arsenic-cerium catalytic spectrophotometry were used to detect salt iodine content and urinary iodine level, respectively, to evaluate the iodine nutritional status of children. Ultrasound was used to detect thyroid volume and analyze the current prevalence of goiter in school-age children.Results:The age of 114 103 children was (9.04 ± 0.81) years old, with 50.0% of (57 083) boys. The median of iodine content M ( Q1, Q3) in children's household salt was 23.00 (19.80, 25.20) mg/kg, including 17 242 non-iodized salt, 6 173 unqualified iodized salt, and 90 688 qualified iodized salt. The coverage rate of iodized salt was 84.89%, and the coverage rate of qualified iodized salt was 79.48%. The proportion of non-iodized salt increased from 11.85% in 2016 to 16.04% in 2021 ( χ 2trend=111.427, P<0.001). The median of urinary iodine concentration M ( Q1, Q3) in children was 182.50 (121.00, 261.00) μg/L, among which the proportions of iodine deficiency, iodine suitability, iodine over suitability, and iodine excess were 17.25% (19 686 cases), 39.21% (44 745 cases), 26.85% (30 638 cases), and 16.68% (19 034 cases), respectively. The median of urinary iodine concentration in children in inland areas [ M ( Q1, Q3): 190.90 (128.80, 269.00) μg/L] was significantly higher than that in children in coastal areas [ M ( Q1, Q3): 173.00 (113.00, 250.30) μg/L] ( P<0.001). From 2016 to 2021, a total of 39 134 ultrasound examinations were conducted, and 1 229 cases of thyroid enlargement were detected. The goiter rate was 3.14% (95% CI: 2.97%-3.32%). The incidence of goiter in children in coastal areas [3.45% (95% CI: 3.19%-3.72%), 641/18 604] was higher than that in children in inland areas [2.86% (95% CI: 2.64%-3.10%), 588/20 530] ( P=0.001). Conclusion:From 2016 to 2021, the iodine nutrition level of children aged 8-10 years in Zhejiang Province is generally suitable, and the rate of goiter in children meets the limit of iodine deficiency disease elimination standards.

A simple, fast, and visual method for detecting antibodies against peste des petits ruminants virus (PPRV) using colloidal gold strips was developed. In this study, the pET-32a-N was transformed into Escherichia coli Rosetta (DE3) for expression. Hybridoma cell lines were generated by fusing SP2/0 myeloma cells with splenocytes from immunized mice with the expressed and purified N protein of PPRV. The PPRV N protein was labeled with colloidal gold particles as the gold-labeled antigen. The N protein served as the gold standard antigen and as the test (T) line-coated antigen, while the monoclonal antibody served as the quality control (C) line-coated antibody to assemble the colloidal gold immunochromatographic test strips for detecting antibodies against the N protein of PPRV. Hybridoma cell line designated as 1F1 was able to stably secrete the monoclonal antibody against the N protein of PPRV. The titer of 1F1 monoclonal antibody in ascites was 1:128 000 determined by indirect enzyme-linked immunosorbent assays (ELISA), and the immunoglobulin subtype of the monoclonal antibody was IgG1, with kappa chain. The obtained monoclonal antibody was able to specifically recognize the N protein of PPRV, as shown by Western blotting and indirect immunofluorescent assay (IFA). The developed colloidal gold test strip method was able to detect PPRV antibodies specifically, and there was no difference between different batches of the test strips. Testing of a total of 122 clinical sera showed that the compliance rate of the test strip with ELISA test was 97.6%.The test strip assay developed in this study has good specificity, reproducibility, and sensitivity, and it can be used for the rapid detection of PPRV antibodies.

Iodine is an essential nutrient required for thyroid hormone synthesis and human growth and development. Iodine requirements increase substantially during pregnancy, and insufficient iodine intake may affect the health of pregnant women, and fetal growth and development. Iodized salt-based iodine supplementation is effective to improve maternal iodine levels, reduce risk of thyroid dysfunctions, and plays a vital role in improvements of offspring growth and development and prevention of intellectual disability. However, excessive iodine supplementation during pregnancy may affect maternal thyroid functions and the nerve development of offspring. Precise and personalized iodine supplementation schemes are therefore required tailored to local iodine deficiency degree and pregnant women's individual iodine status. This review summarizes the advances in the impact of iodine supplementation during pregnancy on maternal and offspring health, so as to provide insights into the guidance of iodine supplementation during pregnancy.

ObjectiveTo analyze the induction effect of Fusobacterium nucleatum （Fn） on endoplasmic reticulum stress-related proteins Glucose-regulating protein 78（GRP78） and X-box binding protein 1（XBP1） in esophageal squamous cell carcinoma （ESCC）， and to explore its potential mechanism and clinical significance. MethodsESCC cells KYSE150 and KYSE140 were infected with Fn for 12 h， 24 h and 48 h. The oxidative stress indexes （ROS， MDA and SOD） and the expression of GRP78 and XBP1 in each group were detected by oxidative stress index kit and Western blot. The experiment was divided into Fn groups， Fn+siNC1 groups， Fn+siGRP78 groups， Fn+siNC2 groups and Fn+siXBP1 groups； the oxidative stress indexes， paclitaxel （PTX） response efficacy， abilities of proliferation， invasion and metastasis in each group were compared. The infection of Fn and the expression of GRP78 and XBP1 in 234 ESCC and paracancerous tissues were detected by RNA scope and immunohistochemistry. The correlation between each factor and clinicopathological characteristics of patients was analyzed by Chi-square test. The influence of each factor on the survival of patients was compared by Kaplan-meier survival estimate. ResultsCompared with Fn uninfected KYSE150 and KYSE140 cells， the content of ROS and MDA was gradually increased， the activity of SOD was gradually decreased， and the expression of GRP78 and XBP1 was gradually increased in Fn infected groups （12 h， 24 h and 48 h） （P < 0.05）. Compared with Fn groups， Fn+siNC1 groups， and Fn+siNC2 groups， ROS and MDA contents were decreased， SOD activity was increased， PTX response efficacy was enhanced， and abilities of proliferation， invasion and metastasis were decreased in Fn+siGRP78 and Fn+siXBP1 groups （P < 0.05）. The rates of Fn， GRP78 and XBP1 in ESCC tissues were 43.16%， 69.66% and 60.68%， respectively. And the three indexes were significantly consistent （P < 0.05）. The patients with positive Fn infection and high expression of GRP78 and XBP1 were mostly males with a history of smoking and drinking， and the tumor differentiation degree was low， the invasion degree was deep， the lymph node metastasis rate was high， and the clinical stage was mostly stage Ⅲ/Ⅳ. The 5-year survival time of patients with above positive indexes was shortened （P < 0.05）. ConclusionsFn could induce endoplasmic reticulum stress by inducing the high expression of GRP78 and XBP1， and promote the malignant evolution of ESCC.

At present, Chinese residents have three iodine nutritional states: iodine deficiency, iodine appropriate and iodine excess. Appropriate iodine nutrition is crucial to the growth, development, and metabolic regulation of the body. Accurate assessment of individual iodine nutrition level is helpful to accurately understand the iodine status of the body and prevent iodine deficiency or excess. Previous indexes for assessing iodine nutrition include urinary iodine, thyroid stimulating hormone, goiter rate and so on, but these indexes have different degrees of shortcomings in individual iodine nutrition evaluation. This paper reviews the commonly used individual iodine nutrition evaluation indexes, and discusses the possibility of combined application of multiple indexes.

Objective:To evaluate the current situation of prevention and control of iodine deficiency disorders (IDD), and to describe the iodine nutrition level of pregnant women in key population in Zhejiang Province.Methods:In 2021, a cross-sectional survey on iodine nutrition status of the population was conducted in all 90 counties (cities, districts) in Zhejiang Province. Each county (city, district) was divided into five districts: east, west, south, north, and central. One township (street) was selected from each district, and 20 pregnant women were selected from each township (street) to collect edible salt samples and one random urine sample for salt and urinary iodine testing. The above indicators were stratified and analyzed according to urban, rural, coastal, inland, early pregnancy, mid pregnancy, and late pregnancy.Results:A total of 9 679 pregnant women's salt samples were tested, with a salt iodine content of (20.2 ± 9.2) mg/kg, an iodized salt coverage rate of 84.2% (8 153/9 679), and a qualified iodized salt consumption rate of 80.4% (7 785/9 679). Among them, the qualified iodized salt consumption rate of pregnant women in coastal areas was 69.4% (3 175/4 575), significantly lower than that in inland areas [90.3% (4 610/5 104)]; and the proportion of non iodized salt consumption in coastal areas [25.8% (1 181/4 575)] was significantly higher than inland areas [6.8% (345/5 104)]. A total of 9 679 pregnant women's urine samples were tested, with a median urinary iodine of 133.0 μg/L ( < 150 μg/L). In urban areas, the median urinary iodine (129.8 μg/L) was lower than that in rural areas (135.0 μg/L). Likewise, the median urinary iodine was 126.0 μg/L, lower than inland areas (140.3 μg/L). And as pregnancy progressed, the iodine nutrition level of pregnant women gradually decreased (the median urinary iodine: 137.0 μg/L in early pregnancy, 134.1 μg/L in mid pregnancy, and 129.4 μg/L in late pregnancy).Conclusion:In 2021, pregnant women in Zhejiang Province are in a state of iodine deficiency, and there is a greater risk in urban areas compared to rural areas and coastal areas compared to inland areas.

ObjectiveTo observe the protective effect and mechanism of Tianhuang formula (THF) against renal injury in hyperuricemia nephropathy (HN) mice through network pharmacology. MethodAll mice were randomly divided into a normal group, a model group, a febuxostat group (5 mg·kg^-1), a low-dose THF group (L-THF, 60 mg·kg^-1), and a high-dose THF group (H-THF, 120 mg·kg^-1). The mice in the normal group were treated with 0.5% sodium carboxymethylcellulose (CMC-Na) by gavage daily. The HN model was induced by oral administration of 500 mg·kg^-1 hypoxanthine and intraperitoneal injection of 200 mg·kg^-1 oteracil potassium in mice except for those in the blank group. The mice in the groups with drug intervention were treated with corresponding drugs by gavage for three weeks. The levels of serum uric acid, creatinine, urea nitrogen, and 24-h albuminuria were measured. The renal injury was observed by hematoxylin-eosin (HE) staining and PAS staining, and renal fibrosis was observed by Sirius red staining. The effects and molecular mechanism of THF in HN mice were analyzed by Western blot, network pharmacology, and molecular docking. ResultBiochemical results indicated that compared with model group, BUN and 24 h urinary protein levels were significantly decreased in L-THF group (P<0.05), SUA and SCr levels were significantly decreased (P<0.01), and SUA, BUN, SCr and 24 h urinary protein levels in H-THF group were significantly decreased (P<0.01). The results of pathological staining showed that the kidney injury and interstitial fibrosis were improved in different doses of THF groups (P<0.05). Western blot results showed that the Nod-like receptor heat protein domain associated protein 3 (NLRP3) inflammatorome, interleukin-1β (IL-1β), fibronectin (FN), uric acid transporter 1 (URAT1), phosphorylated p65 (p-p65) and phosphorylated nuclear transcription factor (NF) -κB were inhibited in the H-THF group The expression of protein-producing α (p-IκBα) was reduced to the normal level (P<0.01), but the expression of IL-1β, URAT1 and p-IκBα in HN mice was not affected in the L-THF group. ConclusionTHF ameliorates renal inflammation and fibrosis by inhibiting the activation of NF-κB and NLRP3 inflammasomes to alleviate HN

Objective: To investigate whether haplotype hematopoietic stem cell transplantation (haplo-HSCT) is effective in the treatment of pre transplant minimal residual disease (Pre-MRD) positive acute B lymphoblastic leukemia (B-ALL) compared with HLA- matched sibling donor transplantation (MSDT) . Methods: A total of 998 patients with B-ALL in complete remission pre-HSCT who either received haplo-HSCT (n=788) or underwent MSDT (n=210) were retrospectively analyzed. The pre-transplantation leukemia burden was evaluated according to Pre-MRD determinedusing multiparameter flow cytometry (MFC) . Results: Of these patients, 997 (99.9% ) achieved sustained, full donor chimerism. The 100-day cumulative incidences of neutrophil engraftment, platelet engraftment, and grades Ⅱ-Ⅳ acute graft-versus-host disease (GVHD) were 99.9% (997/998) , 95.3% (951/998) , and 26.6% (95% CI 23.8% -29.4% ) , respectively. The 3-year cumulative incidence of total chronic GVHD was 49.1% (95% CI 45.7% -52.4% ) . The 3-year cumulative incidence of relapse (CIR) and non-relapse mortality (NRM) of the 998 cases were 17.3% (95% CI 15.0% -19.7% ) and 13.8% (95% CI 11.6% -16.0% ) , respectively. The 3-year probabilities of leukemia-free survival (LFS) and overall survival (OS) were 69.1% (95% CI 66.1% -72.1% ) and 73.0% (95% CI 70.2% -75.8% ) , respectively. In the total patient group, cases with positive Pre-MRD (n=282) experienced significantly higher CIR than that of subjects with negative Pre-MRD [n=716, 31.6% (95% CI 25.8% -37.5% ) vs 14.3% (95% CI 11.4% -17.2% ) , P<0.001]. For patients in the positive Pre-MRD subgroup, cases treated with haplo-HSCT (n=219) had a lower 3-year CIR than that of cases who underwent MSDT [n=63, 27.2% (95% CI 21.0% -33.4% ) vs 47.0% (95% CI 33.8% -60.2% ) , P=0.002]. The total 998 cases were classified as five subgroups, including cases with negative Pre-MRD group (n=716) , cases with Pre-MRD<0.01% group (n=46) , cases with Pre-MRD 0.01% -<0.1% group (n=117) , cases with Pre-MRD 0.1% -<1% group (n=87) , and cases with Pre-MRD≥1% group (n=32) . For subjects in the Pre-MRD<0.01% group, haplo-HSCT (n=40) had a lower CIR than that of MSDT [n=6, 10.0% (95% CI 0.4% -19.6% ) vs 32.3% (95% CI 0% -69.9% ) , P=0.017]. For patients in the Pre-MRD 0.01% -<0.1% group, haplo-HSCT (n=81) also had a lower 3-year CIR than that of MSDT [n=36, 20.4% (95% CI 10.4% -30.4% ) vs 47.0% (95% CI 29.2% -64.8% ) , P=0.004]. In the other three subgroups, the 3-year CIR was comparable between patients who underwent haplo-HSCT and those received MSDT. A subgroup analysis of patients with Pre-MRD<0.1% (n=163) was performed, the results showed that cases received haplo-HSCT (n=121) experienced lower 3-year CIR [16.0% (95% CI 9.4% -22.7% ) vs 40.5% (95% CI 25.2% -55.8% ) , P<0.001], better 3-year LFS [78.2% (95% CI 70.6% -85.8% ) vs 47.6% (95% CI 32.2% -63.0% ) , P<0.001] and OS [80.5% (95% CI 73.1% -87.9% ) vs 54.6% (95% CI 39.2% -70.0% ) , P<0.001] than those of MSDT (n=42) , but comparable in 3-year NRM [5.8% (95% CI 1.6% -10.0% ) vs 11.9% (95% CI 2.0% -21.8% ) , P=0.188]. Multivariate analysis showed that haplo-HSCT was associated with lower CIR (HR=0.248, 95% CI 0.131-0.472, P<0.001) , and superior LFS (HR=0.275, 95% CI 0.157-0.483, P<0.001) and OS (HR=0.286, 95% CI 0.159-0.513, P<0.001) . Conclusion: Haplo HSCT has a survival advantage over MSDT in the treatment of B-ALL patients with pre MRD<0.1% .
