Objective:To investigate the clinical characteristics and prognosis of single center adult chronic myeloid leukemia in chronic phase(CML-CP).Methods:Clinical data of 41 adult CML-CP patients in Department of Hematology,Shanghai Fengxian District Central Hospital from January 2015 to May 2021 were retrospectively analyzed.The clinical characteristics and prognosis of patients between＜60 years group and ≥ 60 years group were compared.Results:The 41 patients included 27(65.9％)males and 14(34.1％)females.The median age of the patients was 56(19-84)years,with 22 cases(53.7％)＜60 years and 19 cases(46.3％)≥60 years.Univariate analysis indicated that the proportions of patients with comorbidities,intermediate/high-risk Sokal score,myelofibrosis,and lactate dehydrogenase ≥1 000 U/L were significantly increased in ≥60 years group compared with＜60 years group at initial diagnosis(all P＜0.05).There were no statistical differences in the distribution of sex,ELST score,white blood cell count,platelet count,peripheral blood basophil percentage,peripheral blood eosinophil percentage and bone marrow primitive cell percentage between the two groups(P＞0.05).The proportion of patients taking reduced-dose imatinib in≥60 years group significantly increased(P＜0.001).Patients＜60 years had a higher proportion of molecular biological remission after treatment of tyrosine kinase inhibitors(TKIs)than patients ≥ 60 years(P＜0.001).The incidence of non-hematologic adverse reactions to TKI therapy significantly increased in patients ≥ 60 years(P＜0.001).Multivariate analysis showed that no adverse factors affecting the efficacy and prognosis of TKI.Conclusion:Compared with adult CML-CP patients＜60 years,patients ≥ 60 years gain fewer benefits from TKI treatment and increased adverse reactions.

The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

Effective treatments for neuropathic pain are lacking due to our limited understanding of the mechanisms. The circRNAs are mainly enriched in the central nervous system. However, their function in various physiological and pathological conditions have yet to be determined. Here, we identified circFhit, an exon-intron circRNA expressed in GABAergic neurons, which reduced the inhibitory synaptic transmission in the spinal dorsal horn to mediate spared nerve injury-induced neuropathic pain. Moreover, we found that circFhit decreased the expression of GAD65 and induced hyperexcitation in NK1R⁺ neurons by promoting the expression of its parental gene Fhit in cis. Mechanistically, circFhit was directly bound to the intronic region of Fhit, and formed a circFhit/HNRNPK complex to promote Pol II phosphorylation and H2B monoubiquitination by recruiting CDK9 and RNF40 to the Fhit intron. In summary, we revealed that the exon-intron circFhit contributes to GABAergic neuron-mediated NK1R⁺ neuronal hyperexcitation and neuropathic pain via regulating Fhit in cis.

Objective To investigate the value of multi-phase MRI-based radiomics machine learning models in differentiating small renal cell carcinoma(sRCC)from fat-poor renal angiomyolipoma(fp-AML).Methods 79 cases of sRCCs and 35 cases of fp-AMLs(diameter≤4 cm)which were confirmed by pathology were retrospectively analyzed.The volume of interest(VOI)of the total tumor was manually delineated on the images of T2WI(T2),unenhanced phase(UP),corticomedullary phase(CMP)and nephrographic phase(NP)and then the radiomics of the VOIs were extracted respectively.The training set and the test set were set according to the ratio of 7∶3.The t-test,maximal relevance and minimal redundancy(mRMR)and the least absolute shrinkage and selection operator(LASSO)were used to select the radiomics features.The selected features were used to build classification models with logistic regression(LR)and support vector machine(SVM).The receiver operating characteristic(ROC)curve was used to evaluate the classification performances of the models.Results There were 4,12,3,11 and 15 optimal features obtained from T2、UP、CMP、NP and the combined four phases,respectively.The radiomics features based on NP or the combined four phases with LR model performed best,AUCs were respectively 0.956,0.986 in the training set and both were 0.881 in the test set.Conclusion The multi-phase MRI-based radiomics machine learning model has favorable diagnostic performance in differentiating sRCC from fp-AML.

[Abstract] Objective To elucidate the important role of Nogo-A in climacteric neurodegeneration such as memory impairment by observing memory function and the expression of Nogo-A in hippocampus and striatum of rats under low estrogen condition. Methods Fouthy-five female SD rats were divided into sham operation group, ovariectomized group and ovariectomized estrogen treatment group with 15 rats in each group. Medication was given 2 weeks after ovariectomized. Estrogen treatment group was subcutaneously injected in groin with estrogen [25 μg/ (kg.d)] dissolved in sterile sesame oil. The sham operation group and the ovariectomized group were given the same amount of aseptic sesame oil. Samples were collected after 6 weeks of drug treatment. The difference of memory function of rats in three groups was observed by conditioned fear training experiment, and the expression of Nogo-A in hippocampus and striatum was observed by immunohistochemistry and Western blotting. Results Compared with the sham and estrogen treatment group, memory function in ovariectomized group decreased significantly and the number of Nogo-A positive neurons in hippocampus and striatum of ovariectomized rats was significantly higher than that of sham operation group (P < 0. 05). There was no difference between the estrogen treatment group and the sham operation group with the memory function and the Nogo-A expression (P > 0. 05). The result of immunoblotting was consistent with the above-mentioned immunohistochemical result. Conclusion The increased expression of Nogo-A in hippocampus and striatum under low estrogen condition may be one of the key reasons for memory impairment in climacteric women.

This study aimed to investigate the development status of traditional Chinese medicine(TCM) intervention in psoriasis in recent ten years, analyze the research hotspots, and summarize the development trends to provide reference materials for scholars in this field. Taking the available literature related to the field of TCM intervention in psoriasis as the research object, the trends, contents, and source publications were statistically analyzed based on bibliometrics. The research cooperation and co-occurrence of keywords in this field were studied by the knowledge map analysis method based on CiteSpace. The total number of Chinese papers was 2 993 and English papers 285. In terms of publication trend, the annual publication of English papers was low but showed an obvious upward trend, while the increase in Chinese papers fluctuated and tended to be flat. In terms of the content of Chinese papers published, TCM ranked first according to the discipline(2 415). In English papers, the number of publications in pharmacology and pharmaceutical science was the highest(87). Literature source analysis showed that the Chinese and English journals with the most publications were China Journal of Traditional Chinese Medicine and Pharmacy and Evidence Based Complementary and Alternative Medicine, respectively. Beijing University of Chinese Medicine published the most dissertations in China(99). The authors with the most publications in Chinese and English were LI Bin(Yueyang Hospital of Integrated Traditional Chinese and Western Medicine Affiliated to Shanghai University of Traditional Chinese Medicine) and LU Chuan-jian(Guangdong Hospital of Traditional Chinese Medicine). As revealed by the CiteSpace analysis of the research cooperation network, there were four mature and stable core teams in this field, but the cooperation intensity between different teams was weak. According to the keywords co-occurrence knowledge graph constructed by CiteSpace, the current hot keywords in this field are as follows: psoriasis, blood-heat syndrome, blood-stasis syndrome, fire needle, blood-dryness type, imiquimod, TCM bath, etiology and pathogenesis, cytokines, cupping therapy, etc. In summary, Chinese scholars have conducted active exploration and research in the field of TCM intervention in psoriasis in recent ten years. The overall development trend is good, and the breadth and depth of the research are constantly extending. It is suggested that relevant research should be free from discipline restrictions and strive for interdisciplinary integration.

OBJECTIVES: To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia. METHODS: A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively. RESULTS: Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia. CONCLUSIONS The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

Intermittent exotropia(IXT)is a common ophthalmic disease with high incidence, variable deviation, and varying degrees of impaired binocular visual function. The defect of binocular visual function is related to the changes of visual cortex. IXT involves the functional changes of many brain regions, including the cortical areas related to binocular fusion. After correcting the eye position, the abnormal changes of cerebral cortex still exist in some patients with IXT, and the recovery of binocular vision is still difficult. In order to solve these problems, visual perception training is gradually applied to the postoperative reconstruction of binocular visual function in patients with IXT. Visual perception training repairs the visual cortex from the brain level, improving the ability of the visual cortex to process information by constantly stimulating the visual center, thus repairing the visual central function, so that patients can obtain good binocular visual function, stabilize the eye position and reduce recurrence. This article reviews the mechanism of binocular visual impairment and the role of visual perception training in the treatment of IXT. It is hoped to provide more evidence for visual perception training to reconstruct postoperative binocular visual function and reduce the recurrence rate in patients with IXT.

Objective:To investigate the correlation between the trajectory of triglyceride-glucose index multiplied by body mass index (TyG×BMI) and the incidence of new-onset non-alcoholic fatty liver disease (NAFLD).Methods:It was a retrospective cohort study. A total of 2 304 subjects who underwent health examinations at the Health Management Center of the First Affiliated Hospital of Zhengzhou University from 2017 to 2019 were included as the study population. Based on the TyG×BMI values from the health examinations, a latent class modeling approach was used to determine four distinct TyG×BMI trajectory groups: low-stable, moderate-stable, high-stable, and extremely high-stable group. The incidence of NAFLD was followed-up during the 2020 and 2021 health examinations for each group. The differences in NAFLD incidence among different TyG×BMI trajectory groups were compared using the log-rank test, and the correlation between different TyG×BMI trajectories and the incidence of new-onset NAFLD was analyzed using Cox proportional hazards regression models.Results:The incidence of NAFLD increased with the elevation of TyG×BMI trajectories. The cumulative incidence rates of NAFLD for the low-stable, moderate-stable, high-stable, and extremely high-stable groups was 13.00%, 16.70%, 20.10% and 26.60%, respectively, with statistically significant differences ( χ2=35.155, P<0.01). Compared with the low-stable group, the high-stable and extremely high-stable groups had higher risks of NAFLD (HRs for high-stable group was 1.564, 1.428, 1.426, 1.289, respectively; HRs for extremely high-stable group was 2.121, 1.670, 1.659, 1.607, respectively; all P<0.05). After adjusting for various confounding factors such as gender, waist circumference, BMI, blood glucose, blood lipids and liver function in model 4, the risks of NAFLD for the high-stable and extremely high-stable groups were still 1.389 and 1.607 times higher than that in the low-stable group (95% CIs: 1.035-1.864, 1.207-2.140). Conclusion:The risk of NAFLD increases with the elevation of TyG×BMI trajectories, suggesting that TyG×BMI can serve as a predictive index for NAFLD.

Objective:To investigate the mediation effect of triglyceride glucose index(TyG) on the relation between thyroid nodules and visceral fat area.Methods:A total of 9 324 individuals at the Health Management Center of the First Affiliated Hospital of Zhengzhou University from January 2017 to December 2021 were selected, and the basic information, biochemical indicators, color ultrasound of thyroid were also collected. According to the cut-off value of visceral fat area(VFA) of 100 cm 2 and body mass index(BMI) of 24 kg/m 2, they were divided into four groups: VFA(-)BMI(-), VFA(-)BMI(+ ), VFA(+ )BMI(-), and VFA(+ )BMI(+ ). Chi-square test was used to compare the incidence rate among the four groups, and multivariate logistic regression analysis to indentify influencing factors. TyG and VFA were quartiled, and multivariate logistic regression analysis was used to explore the effects of TyG and VFA on thyroid nodules. The regression coefficient test was used to analyze whether TyG mediated the association between VFA and thyroid nodules. Results:Multivariate logistic regression analysis revealed that compared with VFA(-)BMI(-) group, the VFA(+ )BMI(-) group had the highest risk of thyroid nodules( OR=1.283, 95% CI 1.064-1.546, P=0.009), followed by VFA(+ )BMI(+ ) group( OR=1.245, 95% CI 1.028-1.508, P=0.025). When using TyG and VFA Q1 group as reference, the Q4 group showed an increased risk of thyroid nodule by 1.584 times(95% CI 1.208-2.077, P=0.001) and 1.573 times(95% CI 1.249-1.982, P<0.001), respectively. Mediation analysis indicated that VFA had a direct impact on the incidence rate of thyroid nodules( β=0.162, 95% CI 0.140-0.186, P<0.001). TyG partially mediated the effect of VFA on the incidence rate of thyroid nodules( β=0.103, 95% CI 0.087-0.121, P<0.001), accounting for 38.87% of the total effect. Conclusions:VFA is an independent risk factor for thyroid nodules regardless of BMI. Among individuals with visceral obesity but normal BMI, the incidence rate of thyroid nodules was the highest. In addition, TyG partially mediates the risk of thyroid nodules in patients with visceral obesity. The evaluation of visceral obesity might be of great significance in the early screening and prevention of thyroid nodules.
