Analysis of the vaccination status of enterovirus type 71 inactivated vaccine in China from 2017 to 2021 / 中华流行病学杂志

Objective: To understand the vaccination status of enterovirus type 71 (EV71) inactivated vaccines in China from 2017 to 2021 and provide evidence for making policy on immunization strategy against hand, foot and mouth disease (HFMD). Methods: Using the reported dose number of EV71 vaccination and birth cohort population data collected by the China immunizaiton program information system to estimate the cumulative coverage of EV71 vaccine by the end of 2021 among the birth cohorts since 2012 at national, provincial, and prefecture levels, and analyze the correlation between the vaccination coverage and the potential influencing factors. Results: As of 2021, the estimated cumulative vaccination coverage of the EV71 vaccine was 24.96% in birth cohorts since 2012. The cumulative vaccination coverage was between 3.09% and 56.59% in different provinces, between 0 and 88.17% in different prefectures. There was a statistically significant correlation between vaccination coverage in different regions and the region's previous HFMD prevalence and disposable income per capita. Conclusions: Since 2017, the EV71 vaccines have been widely used nationwide, but the coverage of EV71 vaccination varies greatly among regions. Vaccination coverage is higher in relatively developed regions, and the intensity of previous epidemic of HFMD may have a certain impact on the acceptance of the vaccine and the pattern of immunization service. The impact of EV71 vaccination on the epidemic of HFMD requires further studies.

Radiomics based on multimodal MRI for the differential diagnosis of benign and malignant lung nodule/mass / 中华放射学杂志

Objective:To develop a multimodal MRI-based radiomics model for the differential diagnosis of benign and malignant lung lesions, and to compare the discriminative abilities of different models.Methods:Totally 114 patients with 115 lesions (44 benign and 71 malignant) in Nantong First Peoples′s Hospital from January 2014 to October 2019 were included in the study. All patients underwent non-enhanced MR examination, and textural features from T 1WI,T 2WI and apparent diffusion coefficient (ADC) imaging were extracted. The feature selection methods included L1 based, mutual information, tree based, recursive feature elimination and F-test. Then we constructed a prediction model by using logistic regression (LR), support vector machine (SVM), random forest (RF) and k-nearest neighbor (KNN) respectively. In order to control the number of modeling features and reduce the ininterpretability of the model, the new model was obtained by manually modifying some parameters of the hyperparameter model. One hundred and fourteen cases were rotated as training and validation sets. The performance of each model was evaluated by confounding matrix and receiver operating characteristic (ROC) curve. Results:The area under the curve (AUC) of T 2WI based LR model for the differential diagnosis of benign and malignant pulmonary nodules/masses was 0.71 and the F1 score was 0.57. Based on T 1WI images, LR and SVM model could be used to identify benign and malignant pulmonary nodules, the AUC before parameter adjustment were 0.77 and 0.78, the accuracy after parameter adjustment (LR a,SVM a) was 0.67, 0.70, and both the AUC were 0.72. However, no matter which feature or classifier was selected, both the AUC and accuracy of ADC-based model were less than 0.70. Conclusion:Multimodal MRI-based radiomics model is valuable for the differential diagnosis of benign and malignant pulmonary nodules/masses, and T 1WI-based model shows the best discrimination.

Pharmacists should take individualized and targeted intervention measures for the above risk factors，which can effectively improve the medication compliance and disease prognosis of patients.

Feasibility of radiofrequency ablation for cancer patients with atrial fibrillation / 中华心血管病杂志

Objective: To analyze the impact of cancer on the recurrence rate of atrial fibrillation (AF) after AF radiofrequency ablation and further evaluate the feasibility of radiofrequency ablation therapy in cancer patients with AF. Methods: This study was a single-center, retrospective study. Cancer patients with AF undergoing radiofrequency ablation for the first time in the First Affiliated Hospital of Dalian Medical University from May 30, 2008 to September 30, 2018 were included (cancer group). AF patients without cancer undergoing radiofrequency ablation for the first time during the same period served as non-cancer group. Clinical data including age, gender, past history, cancer and AF-related parameters, etc. were analyzed. Patients were followed up after radiofrequency ablation. The primary endpoints were AF recurrence or all-cause death. Kaplan-Meier survival analysis was used to analyze the effect of cancers on the recurrence after AF ablation. The multivariate cox regression analysis was further applied to correct for other confounding factors to analyze whether the impact of cancers on the recurrence of atrial fibrillation was statistically significant. Results: A total of 90 patients were enrolled, there were 30 patients in the cancer group (mean age (64.8±6.6) years, 16 (53.3%) males) and 60 patients in the non-cancer group (mean age (63.6±6.2) years, 32 (53.3%) males). Clinical data, such as age, gender, and cancer treatment, were similar between the two groups. During an average follow-up period of (328.7±110.2) days, there were 6 AF recurrences (recurrence rate 20.0%) in the cancer group, and 17 AF recurrences (recurrence rate 28.3%) in the control group. AF recurrence rate was similar between the two groups (P>0.05). During the follow-up period, there was no all-cause death in the two groups. Kaplan-Meier survival analysis showed that cancer was not related to AF recurrence after radiofrequency ablation (P = 0.383). After adjusting for other confounding factors, the multivariate Cox regression analysis showed that cancer was not an independent predictor of AF recurrence after radiofrequency ablation (HR=0.508, 95%CI: 0.192-1.342, P = 0.172). Conclusions: The combination of cancer has no impact on the recurrence of AF after radiofrequency ablation. For cancer patients with AF, radiofrequency ablation therapy can be considered as a feasible heart rhythm control treatment strategy.

A dose-response meta-analysis on the relationship between daily tea intake and cardiovascular mortality based on the GRADE system / 中华心血管病杂志

Objective: To explore the relationship between daily tea intake and cardiovascular disease (CVD) mortality. Methods: PubMed, EMbase, The Cochrane, Chinese Biomedical Literature Database, CNKI, and Wanfang Database were searched to collect research on tea intake and CVD mortality. The search period was from the establishment of the database to June 2020. Two researchers independently screened and extracted literature. The risk of bias was evaluated in the included studies, a dose-response meta-analysis was conducted, sensitivity analysis and publication bias analysis of the research results, and quality evaluation of the included literature and GRADE classification of the evidence body were performed. Results: A total of 21 cohort or case-control studies were included, including 1 304 978 subjects. Among them, 38 222 deaths from CVD were reported. The quality scores of the included studies were all ≥ 6 points. The dose-response meta-analysis showed that for every additional cup of tea intake per day, the mortality rate of CVD decreased by about 3% (95%CI 0.95-0.98, P<0.05), and there was a non-linear dose-response relationship (P<0.05). Compared with people who do not drink tea, people who drink 1 to 8 cups of tea a day have 8% lower CVD mortality (RR=0.92, 95%CI 0.89-0.95), 13% (RR=0.87, 95 %CI 0.84-0.91), 15% (RR=0.85, 95%CI 0.82-0.89), 15% (RR=0.85, 95%CI 0.81-0.89), 16% (RR=0.84, 95%CI 0.80-0.89), 16% (RR=0.84, 95%CI 0.81-0.88), 16% (RR=0.84, 95%CI 0.81-0.87), 16% (RR=0.84, 95%CI 0.80-0.88), respectively. The results of traditional meta-analysis showed that compared with people who do not drink tea, people who drink more than 1 cup of tea a day are associated with 14% lower CVD mortality rate (RR=0.86, 95%CI 0.81-0.91, I2=73.2%, P<0.05). The results of subgroup analysis showed that compared with the corresponding people who did not drink tea, men who drank more than 1 cup of tea a day reduced the CVD mortality rate by 24%, women by 14%, European and American populations by 12%, and Asian populations by 15%. The population who consumed green tea decreased CVD mortality by 15%, and the population of non-smokers decreased CVD mortality by 20% (all P<0.05). The population who consumed black tea decreased CVD mortality by 8%, and the smoking population who consumed black tea decreased CVD mortality by 3%, and the difference was not statistically significant (all P>0.05). The results of the bias analysis showed that Begg=0.42 and Egger=0.62, indicating that the distribution on both sides of the funnel chart is symmetrical, suggesting that there is no publication bias. The results of sensitivity analysis showed that the effect size of the outcome index did not change significantly after excluding any article, indicating that the results are robust and credible. The GRADE evaluation showed that the evidence grades of the outcome indicators were all low grade. Conclusions: Daily tea consumption is related to reduced CVD mortality. It is therefore recommended to drink an appropriate amount of tea daily.

Objective: To evaluate the synergistic anticancer effects of the combination of apigenin (Api) and tanshinone Ⅱ A (Tan IIA), and investigate the mechanisms of pharmacological effects and their potential applications as an anticancer therapy in clinics. Methods: MTT assay were used to determine anticancer effects of the combination of Api and Tan ⅡA on BGC823, MCF7, and SMMC7721 cells. AV-PI dual stain and PI staining method were used for detecting the effect of the two drugs combination on BGC823 cell apoptosis and cell cycle. Expression of p53, BAX/BCL-2, cyclin B1 and D1 proteins were determined by Western blotting. Circular dichroism method and DNA melting point method were explored to detect interaction among the two drugs and DNA. S180 tumor xenograft mice model was used to evaluate the antitumor effects of the two drugs combination. Results: Tan IIA combined with Api exerted synergistic inhibitory effects on the proliferation of BGC823 and other tumor cells with the CI of 0.28. After tumor cell treated by combination of Tan IIA and Api, the tumor cell apoptosis was significantly enhanced and the value of BAX/BCL-2 in cells was up-regulated (P < 0.01); The levels of cyclin B1, D1 protein were changed and cell cycle arrest was increased which mainly blocked in S phase. The interaction among the two drugs and DNA was in two different ways, leading to the curves of thermal denaturation of DNA changed significantly. Furthermore, the combination of Tan IIA and Api showed a stronger inhibitory effect on tumor volume and weight in S180 mice model than monotherapy, which was similar to cyclophosphamide therapy but less side effects. Conclusion Tan IIA combined with Api exerted synergistic antitumor effects. The two drugs interacted with DNA in different ways and aggravated the cell cycle arrest, which were the key mechanisms of their synergistic antitumor effects.

In the course of treatment ，the clinical pharmacist suggested that the subhibernating mixture should be stopped ；Bromocriptine mesylate tablets should be used in combination with continuous hypothermia instrument for physical cooling ，and the treatment course should be at least 10 days according to drug use before admission and medication plan after admission. The doctor adopted the suggestion. The symptoms began to relieve on the third day ，and the symptoms basically disappeared on the 10th day ，then the patient was discharged on the 13th day. The clinical manifestations of NMS were high fever ，myotonia，mental state change ，autonomic nervous disorder ，creatine phosphokinase and leukocyte increase etc. ；risk factors included drug factors ，demographic factors ，genetic and etc. ；the pathogenesis may be associated with dopaminergic receptor block and musculoskeletal fiber toxicity ；the identification diagnosis was based on clinical manifestation，including the onset time ，neuromuscalar reactivity ，remission time ，etc.；the commonly used drugs were bromocriptine mesylate and dantraline.

Efficacy and safety of vitamin D as adjuvant therapy for childhood pneumonia: a Meta analysis / 中国当代儿科杂志

OBJECTIVE@#To study the efficacy and safety of vitamin D as an adjuvant therapy for childhood pneumonia through a systematic review.@*METHODS@#Cochrane Library, PubMed, EMbase, CNKI, Wanfang Data, and Weipu Data were searched for randomized controlled trials (RCTs) of vitamin D as the adjuvant therapy for childhood pneumonia published up to August 2019. Literature screening, quality assessment, and data extraction were performed based on inclusion and exclusion criteria. Revman 5.3 was used to perform the Meta analysis of outcome indicators.@*RESULTS@#A total of 7 RCTs with 1 527 children were included, with 762 children in the vitamin D adjuvant therapy group and 765 children in the control group. The results of the Meta analysis showed that vitamin D adjuvant therapy had no effect on recovery time (P=0.67), length of hospital stay (P=0.73), and time to relief of fever (P=0.43). Furthermore, it did not reduce the recurrence rate (P=0.14), rate of adverse events (P=0.20), and mortality rate (P=0.98) of childhood pneumonia.@*CONCLUSIONS@#Current evidence shows that vitamin D adjuvant therapy has no marked efficacy in the treatment of childhood pneumonia.

Effects of artesunate inhibiting the expression of FOXP3 on proliferation, apoptosis and multidrug resistance of K562/ADR cells / 天津医药

@#Objective To investigate the effect of artesunate inhibiting the expression of FOXP3 on proliferation, apoptosis and multidrug resistance of adriamycin (ADR) -resistant K562/ADR cells in chronic myeloid leukemia (CML), and to explore its mechanism. Methods The expressions of FOXP3 mRNA in K562 and K562/ADR cells were detected by real-time PCR. The expressions of FOXP3 proteins in K562 and K562/ADR cells were detected by Western blot assay. The K562/ADR cells were treated with different concentrations of artesunate (2.5, 5.0, 7.5, 10.0 and 12.5 mg/L) for 24 h. The toxicities of different concentrations of artesunate to K562/ADR cells were detected by CCK-8 assay, and the non-cytotoxic concentrations were screened. The expressions of FOXP3 mRNA and proteins in K562/ADR cells treated by non-cytotoxic concentration of artesunate were detected by RT-PCR and Western blot assay. The changes of toxicities of ADR in K562/ ADR cells were detected by CCK-8 assay. The average fluorescence intensities of ADR were detected by FCM assay. Results The expressions of FOXP3 were higher in K562/ADR cells than those in K562 cells. The mRNA and proteins expressions of FOXP3 were significantly lower in 2.5 mg/L group, 5 mg/L group and 7.5 mg/L group than those in the control group. The toxicities and concentrations of ADR were increased in K562/ADR cells treated by artesunate (both P＜0.05). Conclusion FOXP3 gene is highly expressed in adriamycin-resistant K562/ADR cells in CML. Artesunate can increase the concentrations of ADR and reverse multidrug resistance in K562/ADR cells by inhibiting the expression of FOXP3 in a dose-dependent manner.

Distribution of posterior corneal astigmatism and its effect on the calculation of Toric intraocular lens / 中华实验眼科杂志

Objective To analysis the distribution of posterior corneal astigmatism (PA) and evaluate the influence of keratometric astigmatism (KA) and total corneal astigmatism (TCA) on the calculation of Toric intraocular lens (Toric IOL) in patients with age-related cataract (ARC) and high corneal astigmatism.Methods An observational study design was adopted.Pentacam was used to measure 200 eyes of 181 patients with ARC and KA＞0.75 D in Affiliated Hospital of Nantong University from August 2016 to April 2017.KA,PA,TCA and anterior corneal astigmatism (AA) were recorded.The astigmatism magnitude and axis of PA was studied.The subjects were divided into astigmatism with the rule group,astigmatism against the rule group and oblique astigmatism group according to the axis of AA.The correlations of decomposition values between PA and AA or KA and TCA in each group were analyzed by Pearson linear correlation analysis.The difference of decomposition values between KA and TCA in each group was compared by paired sample t test.The type and axis of Toric IOL were calculated by online formula according to KA and TCA.This study followed the Declaration of Helsinki and written informed consent was obtained from each patient prior to any medical examination.Results The mean astigmatic magnitudes of PA was -0.32 D×93.1°.PA exceeded 0.5 D in 22 eyes (11％).The steepest posterior corneal meridian was vertically aligned in 163 eyes (81.5％).The decomposition value KP(0) and KP (45) of PA were positively correlated with those ofAA (r=0.480,P＜0.001;r=0.251,P＜0.001).The mean astigmatic magnitudes of KA and TCA were 1.44D×89.6° and 1.32 D×89.5° in astigmatism with the rule group,1.39 D×153.4° and 1.71 D×154.4° in astigmatism against the rule group and 1.13 D× 122.0° and 1.24 D× 124.2° in oblique astigmatism group.53 eyes (69.7％) had KA higher than TCA in astigmatism with the rule group.82 eyes (87.3％) had KA lower than TCA in astigmatism against the rule group;20 eyes (66.7％) had KA lower than TCA in oblique astigmatism group.There were significant differences in KP (0) between KA and TCA in different astigmatism groups (all at P＜0.001).The calculated Toric IOL type were inconsistent in 85 eyes(42.5％) and the calculated axis were inconsistent in 176 eye s (88.2％).Conclusions In patients with high corneal astigmatism,the astigmatism type of PA is mostly astigmatism against the rule.Ignoring the PA can lead to deviation of Toric IOL type selection and axis placement in some patients.For patients who cannot measure PA or TCA,the type of Toric IOL should be adjusted appropriately.

In vitro-in vivo correlation of goserelin acetate microspheres / 药学学报

The objective of this paper was to establish a level A in vitro-in vivo correlation (IVIVC) for goserelin acetate extended release microspheres for injection. Three kinds of goserelin acetate microspheres with different release rates were prepared and the critical physicochemical properties, such as drug loading, particle size, glass transition temperature and morphology were characterized. In vitro dissolution test of the prepared goserelin acetate microspheres was performed using sample-and-separate method at 45 ℃ in 5% (v/v) methanol. The morphology of the microspheres and the molecular weight of poly (lactic-co-glycolic acid) (PLGA) of the prepared goserelin acetate microspheres were investigated to research the release mechanism of microspheres. The plasma concentration of goserelin was detected after intramuscular injection of goserelin acetate microspheres to SD rats, and correlated with the in vitro release profiles after processing by percent AUC method. The pharmacokinetic experimental protocol of goserelin acetate microspheres for injection in SD rats was approved by the Animal Ethics Committee of Shandong Luye Pharmaceutical Co., Ltd. The results indicated that the developed sample and separate method was able to detect differences in the release characteristics of the prepared goserelin acetate microspheres, and the in vitro-in vivo correlation of goserelin acetate microspheres was excellent (r > 0.98) and had good predictive ability in SD rats.
