Objective: To compare the clinical effects of endoscopic thyroidectomy using a modified gasless transsubclavian approach and the traditional neck approach for unilateral papillary thyroid carcinoma (cN0). Methods: The clinical data of 135 patients with cN0 papillary thyroid carcinoma who underwent unilateral thyroidectomy in the Department of Thyroid Surgery, the First Hospital of Jilin University from October 2020 to November 2022 were retrospectively analyzed. There were 37 males and 98 females, aging (43.2±8.8) years (range: 21 to 59 years). There were 51 cases using the modified gasless transsubclavian approach (TS group) and 84 cases using the traditional neck approach (TN group). Comparative analyses were performed between the operative results of the 2 groups by t-test, Wilcoxon rank sum test, and χ2 test. Results: All endoscopic operations were successfully completed without conversion to the traditional neck approach. Compared to the TN group, the TS group had a longer operation time (M(IQR)) (73.5 (22.5) minutes vs. 90.0 (30.0) minutes, Z=-5.831, P<0.01), more postoperative drainage (60 (25) ml vs. 95 (45) ml, Z=-6.275, P<0.01), higher hospitalization costs (22 687 (3 488) yuan vs. 26 652 (2 431) yuan, Z=-6.944, P<0.01), and a higher rate of parathyroid autotransplantation (15.5% (13/84) vs. 60.8% (31/51), χ2=29.651, P<0.01). There was no significant difference in the total exposure rate of the central compartment, postoperative hospitalization time, the number of dissected lymph nodes, the number of metastatic lymph nodes, C-reactive protein ratio before and after operation, and preoperative and postoperative parathyroid hormone (all P>0.05). Conclusions: Endoscopic thyroidectomy using the modified gasless transsubclavian approach is safe for cN0 papillary thyroid carcinoma, with longer operating time, more postoperative drainage, higher hospitalization costs, and moredifficulty in preserving the inferior parathyroid gland in situ compared to traditional open surgery.

Investigation and influencing factors on pelvic floor muscle strength of 929 adult females in gynecological outpatient department / 中华妇产科杂志

Objective: To investigate the present situation of pelvic floor muscle strength, and to analyze the factors affecting pelvic floor muscle strength. Methods: The data of patients who were admitted into the general outpatient department of gynecology, Peking University People's Hospital from October 2021 to April 2022 were collected, and the patients who met the exclusion criteria were included in this cross sectional study. The patient's age, height, weight, education level, defecation way and defecation time, birth history, maximum newborn birth weight, occupational physical activity, sedentary time, menopause, family history and disease history were recorded by questionnaire. Morphological indexes such as waist circumference, abdomen circumference and hip circumference were measured with tape measure. Handgrip strength level was measured with grip strength instrument. After performing routine gynecological examinations, the pelvic floor muscle strength was evaluated by palpation with modified Oxford grading scale (MOS). MOS grade>3 was taken as normal group and ≤3 as decreased group. Binary logistic regression was used to investigate the related factors of deceased pelvic floor muscle strength. Results: A total of 929 patients were included in the study, and the average MOS grade was 2.8±1.2. By univariate analysis, birth history, menopausal time, defecation time, handgrip strength level, waist circumference and abdominal circumference were related to the decrease of pelvic floor muscle strength (all P<0.05). By binary logistic regression analysis, the level of handgrip strength (OR=0.913, 95%CI: 0.883-0.945; P<0.001) was correlated with normal pelvic floor muscle strength; waist circumference (OR=1.025, 95%CI: 1.005-1.046; P=0.016), birth history (OR=2.224, 95%CI: 1.570-3.149; P<0.001), sedentary time> 8 hours (OR=2.073, 95%CI: 1.198-3.587; P=0.009) were associated with the decrease of pelvic floor muscle strength. Conclusions: The level of handgrip strength is related to the normal pelvic floor muscle strength of females, while the waist circumference, birth history and sedentary time>8 hours are related to the decrease of pelvic floor muscle strength of females. In order to prevent the decrease of pelvic floor muscle strength, it is necessary to carry out relevant health education, enhance exercise, improve the overall strength level, reduce daily sedentary time, maintain symmetry, and carry out comprehensive overall intervention to improve pelvic floor muscle function.

Progress in research of prophylactic therapy in contacts of rifampicin-resistant tuberculosis patients / 中华流行病学杂志

Tuberculosis (TB) prophylactic therapy for latent infection, which can reduce the risk for the development of active TB, is an important measure in TB control. China recommends prophylactic therapy for latent tuberculosis infection (LTBI) in some key populations to reduce the risk for TB. Contacts of patients with multi-drug and rifampicin-resistant TB (MDR/RR-TB) are at high risk for the infection with drug-resistant pathogen, however, no unified prophylactic therapy regimen has been recommended for LTBI due to exposure to MDR/RR-TB patients. This paper summarizes the current MDR/RR-TB prophylactic therapy regimen and its protection effect based on the results of the retrieval of literature, guidelines, expert consensus and technical specifications to provide reference for the prevention and control of LTBI.

Research progress of ProTide technology and its application in the development of antiviral drugs / 药学学报

ProTide technology is a kind of prodrug design strategy invented by the team of Christopher McGuigan. ProTides are aryloxyphosphoramidates (or aryloxyphosphonamidates) which contain a phosphorus atom combined with an amino acid ester and an aryloxy group. These prodrugs can efficiently cross the cell membrane and escape from the first rate-limiting step of phosphorylation, which afford effective solutions to the drawbacks of current nucleoside analogues. At present, ProTide technology has been extensively applied in the field of antiviral research. It has been successful in providing a number of approved drugs and clinical candidates, such as sofosbuvir and so much more, highlighting the promising future in drug discovery. This review summarizes the brief history and characteristics of ProTide technology, as well as its application in the exploration of antiviral drugs.

AIM: To investigate the postoperative ocular surface changes in acute attack eye and contralateral eye with primary angle-closure glaucoma(PACG)and cataract.METHODS: A total of 40 patients with monocular acute PACG combined with cataract who admitted to Zhengzhou Central Hospital Affiliated to Zhengzhou University from January 2021 to January 2022 were selected. Trabeculectomy combined with phacoemulsification and intraocular lens implantation was carried out in the acute attack eyes, and phacoemulsification and intraocular lens implantation were carried out in the contralateral eyes. The ocular surface disease index(OSDI)questionnaire, noninvasive first tear film break-up time(NifBUT), noninvasive average tear film break-up time(NiaBUT)and tear meniscus height(TMH)were assessed preoperatively and 1, 3 and 6mo postoperatively.RESULTS: The OSDI scores of the included patients at 1 and 3mo postoperatively(14.72±3.07, 11.39±2.24)were significantly higher than those preoperatively(9.68±1.98; all P&#x003C;0.0083), and there was no significant difference between 6mo postoperatively(10.18±1.84)and preoperatively. NifBUT of the acute attack eyes at 1 and 3mo postoperatively was significantly lower than that preoperatively, and NiaBUT of the acute attack eyes at 1, 3 and 6mo postoperatively was significantly lower than that preoperatively(all P&#x003C;0.0083). The NifBUT and NiaBUT of the contralateral eyes at 1mo postoperatively were significantly lower than those preoperatively(all P&#x003C;0.0083), and there was no significant difference between 3 and 6mo postoperatively and preoperatively. There was no significant difference in TMH of the attack eyes and the contralateral eyes postoperatively and preoperatively(P&#x003E;0.05).CONCLUSION: The stability of tear film after surgery of PACG and cataract is decreased. The acute attack eye needs 6mo or even longer to recover, while the contralateral eye needs roughly 3mo.

Drug selection for simultaneous treatment of tuberculosis combined with hepatitis C virus infection / 中华肝脏病杂志

Clinically, patients with tuberculosis (TB) combined with hepatitis C virus (HCV) infection often require simultaneous treatment. Consequently, when anti-HCV and TB drugs are used in combination drug-drug interactions (DDIs), anti-TB drug-induced hepatotoxicity, and liver disease states need to be considered. This paper focuses on discussing the metabolic mechanisms of commonly used anti-TB and HCV drugs and the selection options of combined drugs, so as to provide rational drug use for TB patients combined with HCV infection.

Analysis of vitamin D status among children under 7 years of age in some regions of China / 中华儿科杂志

Objective: To explore current vitamin D status and influential factors of vitamin D deficiency and insufficiency among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China. Methods: According to the "province-city-hospital" sampling technical route, a total of 1 531 healthy children under 7 years of age were sampled from 11 provinces, autonomous regions or municipalities in China by the cluster random sampling method from November 2020 to November 2021. The demographic information, family conditions, behavior and living habits and feeding behaviors were collected using unified questionnaire. Serum 25-hydroxyvitamin D(25(OH)D) levels were measured by liquid chromatography-tandem mass spectrometry. Serum 25(OH)D<30 nmol/L was considered deficient and 30-50 nmol/L was considered insufficient. With 25(OH)D≤50 nmol/L as the dependent variable, multivariate Logistic regression was applied to analyze the association between vitamin D deficiency and insufficiency and potential influential factors. Results: The prevalence of vitamin D deficiency and insufficiency among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China was 14.0% (215/1 531), 3.8% (25/664) and 21.9% (190/867) in 0-<3 and 3-<7 of age years, respectively. Compared to children aged 0-<3 years, children aged 3-<7 years had a 2.6-fold increased risk of vitamin D deficiency and insufficiency (OR=3.60, 95%CI 1.93-6.72, P<0.001). Frequent sunlight exposure (OR=0.46, 95%CI 0.29-0.73, P=0.001), vitamin D supplementation (sometimes, OR=0.33, 95%CI 0.21-0.51, P<0.001; daily, OR=0.20, 95%CI 0.11-0.36, P<0.001) and infant formula intake(4-7 times per weeks, OR=0.43, 95%CI 0.28-0.68, P<0.001) were protective factors for vitamin D deficiency and insufficiency. Conclusion: Vitamin D deficiency and insufficiency are common among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China, which is affected by age, sunlight exposure, vitamin D supplementation and infant formula intake.

Analysis of clinical features and risk factors of necrotizing pneumonia in children / 北京大学学报(医学版)

OBJECTIVE@#To investigate the clinical characteristics and risk factor analysis of necrotizing pneumonia in children.@*METHODS@#A retrospective study was used to analyze the case data of 218 children with severe pneumonia hospitalized in the Department of Respiratory Medicine, Children's Hospital of Capital Institute of Pediatrics from January 2016 to January 2020, and they were divided into 96 cases in the necrotizing pneumonia group (NP group) and 122 cases in the non-necrotizing pneumonia group (NNP group) according to whether necrosis of the lung occurred. The differences in clinical characteristics (malnutrition, fever duration, hospitalization time, imaging performance, treatment and regression follow-up), laboratory tests [leukocytes, neutrophil ratio, platelet (PLT), C-reactive protein (CRP), procalcitonin (PCT), D-dimer, and lactate dehydrogenase (LDH)] and bronchoscopic performance between the two groups were compared, and Logistic regression analysis of clinical risk factors associated with necrotizing pneumonia was performed to further determine the maximum diagnostic value of each index by subject operating characteristic curve (ROC). The critical value of each index was further determined by the ROC.@*RESULTS@#The differences in age, gender, pathogenic classification, and bronchoscopic presentation between the two groups of children were not statistically significant (P>0.05); whereas the imaging uptake time of the children in the NP group was higher than that in the NNP group (P < 0.05). The differences in malnutrition, fever duration, length of stay, white blood cell count, neutrophil ratio, CRP, PCT, and D-dimer were statistically significant between the two groups (P < 0.05). The imaging uptake time was lower in children under 6 years of age than in those over 6 years of age, and the imaging uptake time for bronchoalveolar lavage within 10 d of disease duration was lower than that for those over 10 d; the imaging uptake time was significantly longer in the mixed infection group than that in the single pathogen infection group. Logistic regression analysis of the two groups revealed that the duration of fever, hospital stay, CRP, PCT, and D-dimer were risk factors for secondary pulmonary necrosis (P < 0.001, P < 0.001, P < 0.001, P=0.013, P=0.001, respectively). The ROC curves for fever duration, CRP, PCT, and D-dimer were plotted and found to have diagnostic value for predicting the occurrence of pulmonary necrosis when fever duration >11.5 d, CRP >48.35 mg/L, and D-dimer > 4.25 mg/L [area under ROC curve (AUC)=0.909, 0.836, and 0.747, all P < 0.001].@*CONCLUSION@#Children with necrotizing pneumonia have a longer heat course and hospital stay, and the imaging uptake time of mixed pathogenic infections is significantly longer than that of single pathogenic infections. Children with necrotizing pneumonia under 6 years of age have more advantageous efficacy of electronic bronchoscopic alveolar lavage within 10 d of disease duration compared with children in the group over 6 years of age and children in the group with disease duration >10 d. Inflammatory indexes CRP, PCT, and D-dimer are significantly higher. The heat course, CRP, PCT, and D-dimer are risk factors for secondary lung necrosis in severe pneumonia. Heat course >11.5 d, CRP >48.35 mg/L, and D-dimer >4.25 mg/L have high predictive value for the diagnosis of necrotizing pneumonia.

Historical Evolution and Clinical Application of Classical Prescription Xiao Xumingtang / 中国实验方剂学杂志

Xiao Xumingtang in The Catalogue of Famous Ancient Classics （The First Batch） issued by the National Administration of Traditional Chinese Medicine is derived from the Important Prescriptions Worth a Thousand Gold for Emergency （Bei Ji Qian Jin Yao Fang） written by SUN Si-miao in the Tang dynasty. The present study systematically explored the origin， development， historical evolution， and clinical application of Xiao Xumingtang. As revealed by the results， Xiao Xumingtang as well as its analogues are primary prescriptions indicated for apoplexy before the Tang and Song dynasties and serve as the benchmark for the treatment of apoplexy. After the Song dynasty， due to the changes in the understanding of the pathogenesis of apoplexy and the limitations of the understanding of Xiao Xumingtang， its clinical application to apoplexy gradually decreased. In modern times， it has been re-recognized and applied， during which its clinical applications have undergone great changes. Its clinical applications are extensive， involving a variety of diseases related to the brain and nervous systems， such as stroke and its sequelae， peripheral facial paralysis， rheumatoid arthritis， hypertension， and other diseases related to the motor nervous system. Its primary indications are stroke and its sequelae， followed by peripheral facial paralysis. Other new indications are gradually found. This study is expected to provide references for the clinical application of Xiao Xumingtang and the transformation of new drugs.

Histone methylation and diabetic cardiomyopathy / 生理学报

Histone methylation is one of the key post-translational modifications that plays a critical role in various heart diseases, including diabetic cardiomyopathy. A great deal of evidence has shown that histone methylation is closely related to hyperglycemia, insulin resistance, lipid and advanced glycation end products deposition, inflammatory and oxidative stress, endoplasmic reticulum stress and cell apoptosis, and these pathological factors play an important role in the pathogenesis of diabetic cardiomyopathy. In order to provide a novel theoretical basis and potential targets for the treatment of diabetic cardiomyopathy from the perspective of epigenetics, this review discussed and elucidated the association between histone methylation and the pathogenesis of diabetic cardiomyopathy in details.

Research progress of therapeutic exosomes / 药学学报

Exosomes are a kind of endosomal vesicles that are secreted by most if not all living cells. Due to their capability of delivering a variety of cargos, such as tissue- or cell-specific proteins, lipids, and genetic materials, and their broad biological activities, exosomes have gained substantial attention as emerging therapeutics. Exosomes derived from mesenchymal stem cells (MSCs) and dendritic cells (DCs) are two types of exosomes that are widely studied. Many preclinical and clinical studies have shown that they have a satisfactory treatment effect in lung diseases, liver diseases, nervous system diseases, tumors, and other diseases. In addition, exosomes from macrophages, tumor cells, plant cells, and many other cells are getting more attention due to their therapeutic potential. Besides natural exosomes, research on engineered exosomes has also made plenty of progress. There have been several engineering methods of exosomes, such as targeting modification and loading of active ingredients. In this review, we summarize the research progress of therapeutic exosomes from different sources, and further discusses the application prospects of exosomes and possible challenges in the future.

Method:Based on the ultraperformance liquid chromatography mass spectrometry（UPLC-MS/MS） detection platform，the secondary metabolites database of <italic>C. chinensis</italic> and its flower stalk（MWDB） was built. The common database of metabolites information and the multivariate statistical analysis were used to study the differences of secondary metabolites between <italic>C. chinensis</italic> and its flower stalk and screen out 18 metabolites of<italic> </italic>the<italic> </italic>flower stalk and 11 metabolites of <italic>C. chinensis</italic> with a high content. BATMAN-TCM database was used to obtain the targets of component action，and their corresponding genes were inquired in the UniProt database. GeneCards was retrieved for antimicrobial genes，and the intersection genes of components and antimicrobials were obtained on Venny platform. Through DAVID gene ontology（GO） enrichment analysis and Kyoto encyclopedia of genes and genomes（KEGG） pathway enrichment analysis，the mechanism of its action was predicted，and the results were visualized through histogram and advanced bubble diagram drawn by GraphPad Prism software and OmicShare database. The protein-protein interaction（PPI） network was constructed by STRING， database and the component-target-pathway network was constructed by Cytoscape 3.7.2 software. The antibacterial differences were compared based on the results of network pharmacology analysis. Result:Through network pharmacology，the antibacterial active components of <italic>C. chinensis</italic> were 5 fewer than that of the flower stalk，55 more antibacterial targets than that of the flower stalk； quercetin and berberine were predicted to be the common components of the antagonistic action of <italic>C. chinensis </italic>and the flower stalk. Key genes involved in antimicrobial action were p38 Mitogen-activated protein kinase 14（MAPK14），catalase（CAT）； malaria and Toll-like receptor signaling pathway were different key pathways involved in antimicrobial activity. Conclusion:<italic>C. chinensis </italic>and the flower stalk mainly exert the antibacterial effect in a multi-target and multi-pathway manner，which can offer new ideas and clues for the study of antibacterial mechanism of<italic> C. chinensis</italic> and the flower stalk，and provide a new development direction for the comprehensive development and rational application of the flower stalk resources.

The Positive Association between Subclinical Hypothyroidism and Newly-Diagnosed Hypertension Is More Explicit in Female Individuals Younger than 65

Background@#Subclinical hypothyroidism (SCH) is the most common thyroid dysfunction, and its relationship with blood pressure (BP) has been controversial. The aim of the study was to analyze the association between SCH and newly-diagnosed hypertension. @*Methods@#Based on data from the Thyroid disease, Iodine nutrition and Diabetes Epidemiology (TIDE) study, 49,433 euthyroid individuals and 7,719 SCH patients aged ≥18 years were enrolled. Patients with a history of hypertension or thyroid disease were excluded. SCH was determined by manufacturer reference range. Overall hypertension and stage 1 and 2 hypertension were diagnosed according to the guidelines issued by the American College of Cardiology/American Heart Association in 2017. @*Results@#The prevalence of overall hypertension (48.7%), including stage 1 (28.9%) and 2 (19.8%) hypertension, increased significantly in SCH patients compared with euthyroid subjects. With elevated serum thyroid stimulating hormone (TSH) level, the hypertension prevalence also increased significantly from the euthyroid to different SCH subgroups, which was more profound in females or subjects aged <65 years. The age- and sex-specific regression analysis further demonstrated the same trends in the general population and in the 1:1 propensity matched population. Similarly, several BP components (i.e., systolic, diastolic, and mean arterial BP) were positively associated with TSH elevation, and regression analysis also confirmed that all BP components were closely related with SCH in female subjects aged <65 years. @*Conclusion@#The prevalence of hypertension increases for patients with SCH. SCH tends to be associated with hypertension and BP components in females younger than 65 years.

Objective To evaluate the relationship between the platelet reactivity detected by two methods and CYP2C19 gene polymorphism in patients with ACS after taking clopidogrel, and analyze the correlation between different platelet detection methods. Methods Forty-three patients with ACS, admitted in the General Hospital of Northern Theater Command from July to October 2019, met the diagnostic criteria and received dual antiplatelet therapy, were enrolled in present study. The gene chip was used for CYP2C19 genotype detection, vasodilatory stimulated phosphorylated protein (VASP) method and two revulsiveinduced phototurbidimetric methods [arachidonic acid-induced phototurbidimetry (AA-LTA), diphosphate adenosine-induced phototurbidimetry (ADP-LTA)] were used to evaluate the antiplatelet reactivity, and the correlation between different evaluation methods was compared. Results Of the 43 patients, 17(39.5%) were EMs, 19(44.2%) were IMs, and 7(16.3%) were PMs. The results of VASP were higher in PMs and IMs patients than those in EMs, and the results of AA-LTA were higher in PMs than those in IMs and EMs. The differences were significant (P<0.01). The platelet reactivity of VASP was positively correlated with AA-LTA and ADP-LTA (r=0.383, 0.369, P<0.05); and AA-LTA was positively correlated with ADP-LTA (r=0.496, P=0.011). Conclusions There is a difference between CYP2C19 gene polymorphism and platelet reactivity, and the correlation between VASP method and LTA method is low. CYP2C19 genotype can be used as a reference for the platelet reactivity of patients after clopidogrel therapy.

Effect of diabetes mellitus and blood sugar status on treatment outcome of tuberculosis patients / 中华疾病控制杂志

Diabetes mellitus patients are at high risk of tuberculosis, and tuberculosis is one of the important reasons for inducing and aggravating acute complications of diabetes. At present, China is facing a serious dual epidemic of tuberculosis and diabetes, which has caused great harm to the health of our people, but also brought great burden to our social economy. In this paper, PubMed, Web of Science, CNKI and Wanfang data knowledge service platform were used to search the relevant literature. Research progress on the epidemiology of tuberculosis patients complicated with diabetes, the effect of diabetes and blood glucose on the treatment outcome of tuberculosis patients, and the mechanism of diabetes affecting the treatment outcome of tuberculosis patients were analyzed and summarized, and some references were provided for the treatment and management of tuberculosis patients in China in the future.

Epigenetic Landscape Changes Due to Acupuncture Treatment: From Clinical to Basic Research / 中国结合医学杂志

Acupuncture has been widely used for treating diseases since the ancient days in China, but the mechanism by which acupuncture exerts such powerful roles is unclear. Epigenetics, including DNA methylation, histone modification, and post-transcriptional regulation of miRNAs, is the study of heritable changes in gene expression that do not include DNA sequence alterations. Epigenetics has become a new strategy for the basic and clinical research of acupuncture in the last decade. Some investigators have been trying to illustrate the mechanism of acupuncture from an epigenetics perspective, which has shed new lights on the mechanisms and applications of acupuncture. Moreover, the introduction of epigenetics into the regulatory mechanism in acupuncture treatment has provided more objective and scientific support for acupuncture theories and brought new opportunities for the improvement of acupuncture studies. In this paper, we reviewed the literatures that has demonstrated that acupuncture could directly or indirectly affect epigenetics, in order to highlight the progress of acupuncture studies correlated to epigenetic regulations. We do have to disclose that the current evidence in this review is not enough to cover all the complex interactions between multiple epigenetic modifications and their regulations. However, the up-to-date results can help us to better understand acupuncture's clinical applications and laboratory research.
