Objective:To assess the diagnostic utility of ultrasound-guided fine-needle aspiration (FNA) combined with BRAF V600E gene mutation detection for discerning benign from malignant thyroid isthmus nodules classified as thyroid imaging report and data system (TI-RADS) 4a and 4b. Methods:A retrospective analysis was conducted on the clinical data of 48 patients with thyroid nodules of TI-RADS 4, who underwent surgical confirmation and pathological diagnosis at Jiaozuo People's Hospital between October 2019 and June 2022. Using surgical and pathological outcomes as the gold standard, the diagnostic efficacy of FNA cytopathology, BRAF V600E gene mutation detection, and the combined approach were individually evaluated for benign and malignant thyroid nodules of TI-RADS 4. Results:The receiver operating characteristic curve analysis revealed the diagnostic values of FNA, BRAF V600E gene mutation detection, and their combined use in predicting the benignancy or malignancy of thyroid isthmus nodules. For TI-RADS 4a nodules, the areas under the curves were 0.876 for FNA, 0.852 for BRAF V600E gene mutation detection, and 0.952 for the combined approach. For TI-RADS 4b nodules, the areas under the curves were 0.850, 0.858, and 0.908, respectively. The P-values were 0.010, 0.016, and 0.002 for TI-RADS 4a nodules, and 0.006, 0.005, and 0.001 for TI-RADS 4b nodules. Notably, the combined approach demonstrated larger areas under the curves compared with individual applications. Conclusion:The combined use of FNA and BRAF V600E gene mutation detection enhances the diagnostic accuracy for thyroid isthmus nodules classified as TI-RADS 4a and 4b, as reflected by an increased area under the receiver operating characteristic curve.

Correlation between tear inflammatory factors and postoperative complications in glaucoma patients after trabeculectomy / 局解手术学杂志

Objective To investigate the application value of tear inflammatory factors in early evaluation of the occurrence of complications after trabeculectomy in glaucoma patients.Methods A total of 150 eyes of 150 patients with angle-closure glaucoma who underwent trabeculectomy in Department of Ophthalmology of Zhangjiagang Hospital of Traditional Chinese Medicine were included.The clinical data of all patients were collected,and the levels of inflammatory factors(including G-CSF,GM-CSF,IFN-γ,MCP-1,TNF-α,IL-12,IL-13,IL-15,IL-1β,IL-4,IL-7,IL-10,IL-17,IL-5)in tears were detected before surgery.According to the occurrence of postoperative complications,the patients were divided into the complication group and the control group,and the clinical data of the two groups were compared.Logistic regression was used to analyze the related factors of the occurrence of complications after trabeculectomy in glaucoma patients.The predictive model of tear inflammatory factors was established by Logistic regression,and the receiver operating characteristic(ROC)curve was drawn to analyze the value of this model in early evaluation of the occurrence of complications after trabeculectomy in glaucoma patients.Results Complications occurred in 35(23.33%)of 150 glaucoma patients after trabeculectomy,including 24 cases of shallow anterior chamber,5 cases of ciliary body or choroid detachment,3 cases of iridocyclitis,2 cases of hyphema,and 1 case of retinal detachment.IFN-γ,GM-CSF and IL-5 levels of the patients in the complication group were lower than those in the control group(P<0.05).There was no significant difference in the levels of other inflammatory factors of patients between the two groups(P>0.05).Multivariate Logistic regression analysis showed that increased levels of IFN-γ(OR=0.999),GM-CSF(OR=0.988)and IL-5(OR=0.996)were independent protective factors for complications after trabeculectomy in glaucoma patients(P<0.05).ROC curve analysis showed that the sensitivity and specificity of the model were 94.29%and 83.84%in early evaluation of the occurrence of complications after trabeculectomy in glaucoma patients,and the AUC was 0.906,which was higher than that predicted by IFN-γ(AUC=0.642),GM-CSF(AUC=0.721)and IL-5(AUC=0.666)alone.Conclusion Preoperative analysis of tear inflammatory factors in glaucoma patients can early evaluate the occurrence of postoperative complications,especially the combined detection of IFN-γ,GM-CSF and IL-5 levels is of great significance for predicting the occurrence of complications.

Tumor Therapy: Targeted Substances Metabolism Reprogramming Induces Tumor Ferroptosis / 生物化学与生物物理进展

There are huge differences between tumor cells and normal cells in material metabolism, and tumor cells mainly show increased anabolism, decreased catabolism, and imbalance in substance metabolism. These differences provide the necessary material basis for the growth and reproduction of tumor cells, and also provide important targets for the treatment of tumors. Ferroptosis is an iron-dependent form of cell death characterized by an imbalance of iron-dependent lipid peroxidation and lipid membrane antioxidant systems in cells, resulting in excessive accumulation of lipid peroxide, causing damage to lipid membrane structure and loss of function, and ultimately cell death. The regulation of ferroptosis involves a variety of metabolic pathways, including glucose metabolism, lipid metabolism, amino acid metabolism, nucleotide metabolism and iron metabolism. In order for tumor cells to grow rapidly, their metabolic needs are more vigorous than those of normal cells. Tumor cells are metabolically reprogrammed to meet their rapidly proliferating material and energy needs. Metabolic reprogramming is mainly manifested in glycolysis and enhancement of pentose phosphate pathway, enhanced glutamine metabolism, increased nucleic acid synthesis, and iron metabolism tends to retain more intracellular iron. Metabolic reprogramming is accompanied by the production of reactive oxygen species and the activation of the antioxidant system. The state of high oxidative stress makes tumor cells more susceptible to redox imbalances, causing intracellular lipid peroxidation, which ultimately leads to ferroptosis. Therefore, in-depth study of the molecular mechanism and metabolic basis of ferroptosis is conducive to the development of new therapies to induce ferroptosis in cancer treatment. Ferroptosis, as a regulated form of cell death, can induce ferroptosis in tumor cells by pharmacologically or genetically targeting the metabolism of substances in tumor cells, which has great potential value in tumor treatment. This article summarizes the effects of cellular metabolism on ferroptosis in order to find new targets for tumor treatment and provide new ideas for clinical treatment.

Comprehensive analysis of insulin products complex disulfide bonds structure by high resolution mass spectrum / 药学学报

The correct pairing of disulfide bonds maintains the correct folding mode and high-level structure formation of peptides and protein drugs, which is crucial for the quality control of products. In order to ensure that the disulfide bonds are correctly paired, disulfide bond analysis is an essential part of peptides and protein drug characterization. Mass spectrometry can be used to analyze disulfide bonds. However, insulin and its analogues have two pairs of disulfide bonds without restriction enzyme cutting site. Conventional collision-induced dissociation (CID) and high-energy induced cleavage (HCD) cannot accurately locate the complex disulfide bond. In our study, three methods were used to localize the complex disulfide, including enzyme digestion combined with key peptide fragment in source decay (ISD) fragmentation method, enzyme digestion combined with partial reduction alkylation method, intact protein source ISD and electron transfer dissociation (ETD) cleavage method, The applicability of insulin aspart, insulin lispro and insulin glargine were also investigated. This study provides a new way for the quality control of disulfide bonding mode of insulin and its analogues, and also provides a reference for the disulfide bond localization of peptides or proteins containing this complex disulfide bond.

Swyer syndrome with gonadal non-dysgerminoma malignant germ cell tumors: a report of 15 cases in a national medical center / 中华妇产科杂志

Objective: To evaluate the incidence, treatment, and survival outcomes of Swyer syndrome with gonadal non-dysgerminoma malignant germ cell tumor (MGCT-NDG). Methods: A retrospective study was performed on Swyer syndrome patients with MGCT-NDG between January 2011 and December 2022 in Peking Union Medical College Hospital to investigate their characteristics and outcomes. Results: A total of 15 patients (4.9%, 15/307) with Swyer syndrome were identified in 307 MGCT-NDG patients. The average age at diagnosis of MGCT-NDG and Swyer syndrome were (16.8±6.7) and (16.7±6.6) years, respectively. Six cases were preoperatively diagnosed as Swyer syndrome, of which 4 cases received bilateral gonadectomy with or without hysterectomy, while the other 2 cases underwent removal of gonadal tumor and unilateral gonadectomy with hysterectomy, respectively. Of the 9 patients postoperatively diagnosed as Swyer syndrome, unilateral gonadectomy, removal of gonadal tumor, and unilateral gonadectomy with hysterectomy were performed in 6 patients, 2 patients, and 1 patient, respectively. Mixed malignant germ cell tumor (MGCT;10 cases), yolk sac tumor (4 cases), and immature teratoma (1 case) were the pathological subtypes, in the descending order. There were International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ in 6 cases, stage Ⅱ in 3 cases, stage Ⅲ in 5 cases, and stage Ⅳ in 1 case, respectively. Eleven patients received reoperation for residual gonadectomy after a average delay of (7.9±6.2) months, including 8 MGCT-NDG patients and 1 gonadoblastoma patient, no tumor involved was seen in the remaining gonads in the other 2 cases. Ten patients experienced at least one recurrence, with a median event free survival of 9 months (5, 30 months), of which 2 patients received surgery only at the time of initial treatment. All patients with recurrence received surgery and combined with postoperative chemotherapy. After a median follow-up of 25 months (15, 42 months), 10 patients were disease-free, 3 patients died of the tumor, 1 died of side effects of leukemia chemotherapy, and 1 survived with disease. Conclusion: The incidence rate of Swyer syndrome in patients with MGCT-NDG is about 4.9%; timely diagnosis and bilateral gonadectomy should be emphasized to reduce the risk of reoperation and second carcinogenesis in this population.

Objective: To describe the current status and trends in the outcomes and care practices of extremely preterm infants at 22-25 weeks' gestation age from the Chinese Neonatal Network (CHNN) from 2019 to 2021. Methods: This cross-sectional study used data from the CHNN cohort of very preterm infants. All 963 extremely preterm infants with gestational age between 22-25 weeks who were admitted to neonatal intensive care units (NICU) of the CHNN from 2019 to 2021 were included. Infants admitted after 24 hours of life or transferred to non-CHNN hospitals were excluded. Perinatal care practices, survival rates, incidences of major morbidities, and NICU treatments were described according to different gestational age groups and admission years. Comparison among gestational age groups was conducted using χ2 and Kruskal-Wallis tests. Trends by year were evaluated by Cochran-Armitage and Jonckheere-Terpstra tests for trend. Results: Of the 963 extremely preterm infants enrolled, 588 extremely preterm infants (61.1%) were male. The gestational age was 25.0 (24.4, 25.6) weeks, with 29 extremely preterm infants (3.0%), 88 extremely preterm infants (9.1%), 264 extremely preterm infants (27.4%), and 582 extremely preterm infants (60.4%) at 22, 23, 24, and 25 weeks of gestation age, respectively. The birth weight was 770 (680, 840) g. From 2019 to 2021, the number of extremely preterm infants increased each year (285, 312, and 366 extremely preterm infants, respectively). Antenatal steroids and magnesium sulfate were administered to 67.7% (615/908) and 51.1% (453/886) mothers of extremely preterm infants. In the delivery room, 20.8% (200/963) and 69.5% (669/963) extremely preterm infants received noninvasive positive end-expiratory pressure support and endotracheal intubation. Delayed cord clamping and cord milking were performed in 19.0% (149/784) and 30.4% (241/794) extremely preterm infants. From 2019 to 2021, there were significant increases in the usage of antenatal steroids, antenatal magnesium sulfate, and delivery room noninvasive positive-end expiratory pressure support (all P<0.05). Overall, 349 extremely preterm infants (36.2%) did not receive complete care, 392 extremely preterm infants (40.7%) received complete care and survived to discharge, and 222 extremely preterm infants (23.1%) received complete care but died in hospital. The survival rates for extremely preterm infants at 22, 23, 24 and 25 weeks of gestation age were 10.3% (3/29), 23.9% (21/88), 33.0% (87/264) and 48.3% (281/582), respectively. From 2019 to 2021, there were no statistically significant trends in complete care, survival, and mortality rates (all P>0.05). Only 11.5% (45/392) extremely preterm infants survived without major morbidities. Moderate to severe bronchopulmonary dysplasia (67.3% (264/392)) and severe retinopathy of prematurity (61.5% (241/392)) were the most common morbidities among survivors. The incidences of severe intraventricular hemorrhage or periventricular leukomalacia, necrotizing enterocolitis, and sepsis were 15.3% (60/392), 5.9% (23/392) and 19.1% (75/392), respectively. Overall, 83.7% (328/392) survivors received invasive ventilation during hospitalization, with a duration of 22 (10, 42) days. The hospital stay for survivors was 97 (86, 116) days. Conclusions: With the increasing number of extremely preterm infants at 22-25 weeks' gestation admitted to CHNN NICU, the survival rate remained low, especially the rate of survival without major morbidities. Further quality improvement initiatives are needed to facilitate the implementation of evidence-based care practices.

Associations of sex hormone levels with body mass index (BMI) in men: a cross-sectional study using quantile regression analysis / 亚洲男科学杂志(英文版)

Body mass index (BMI) has been increasing globally in recent decades. Previous studies reported that BMI was associated with sex hormone levels, but the results were generated via linear regression or logistic regression, which would lose part of information. Quantile regression analysis can maximize the use of variable information. Our study compared the associations among different regression models. The participants were recruited from the Center of Reproductive Medicine, The First Hospital of Jilin University (Changchun, China) between June 2018 and June 2019. We used linear, logistic, and quantile regression models to calculate the associations between sex hormone levels and BMI. In total, 448 men were included in this study. The average BMI was 25.7 (standard deviation [s.d.]: 3.7) kg m-2; 29.7% (n = 133) of the participants were normal weight, 45.3% (n = 203) of the participants were overweight, and 23.4% (n = 105) of the participants were obese. The levels of testosterone and estradiol significantly differed among BMI groups (all P < 0.05). In linear regression and logistic regression, BMI was associated with testosterone and estradiol levels (both P < 0.05). In quantile regression, BMI was negatively associated with testosterone levels in all quantiles after adjustment for age (all P < 0.05). BMI was positively associated with estradiol levels in most quantiles (≤80th) after adjustment for age (all P < 0.05). Our study suggested that BMI was one of the influencing factors of testosterone and estradiol. Of note, the quantile regression showed that BMI was associated with estradiol only up to the 80th percentile of estradiol.

A novel and low-toxic peptide DR3penA alleviates pulmonary fibrosis by regulating the MAPK/miR-23b-5p/AQP5 signaling axis

Pulmonary fibrosis (PF) is a pathological change caused by repeated injuries and repair dysfunction of the alveolar epithelium. Our previous study revealed that the residues Asn3 and Asn4 of peptide DR8 (DHNNPQIR-NH2) could be modified to improve stability and antifibrotic activity, and the unnatural hydrophobic amino acids α-(4-pentenyl)-Ala and d-Ala were considered in this study. DR3penA (DHα-(4-pentenyl)-ANPQIR-NH2) was verified to have a longer half-life in serum and to significantly inhibit oxidative damage, epithelial-mesenchymal transition (EMT) and fibrogenesis in vitro and in vivo. Moreover, DR3penA has a dosage advantage over pirfenidone through the conversion of drug bioavailability under different routes of administration. A mechanistic study revealed that DR3penA increased the expression of aquaporin 5 (AQP5) by inhibiting the upregulation of miR-23b-5p and the mitogen-activated protein kinase (MAPK) pathway, indicating that DR3penA may alleviate PF by regulating MAPK/miR-23b-5p/AQP5. Safety evaluation showed that DR3penA is a peptide drug without obvious toxicity or acute side effects and has significantly improved safety compared to DR8. Thus, our findings suggest that DR3penA, as a novel and low-toxic peptide, has the potential to be a leading compound for PF therapy, which provides a foundation for the development of peptide drugs for fibrosis-related diseases.

Mechanism of Fructus Lycii against dry eye: an analysis based on network pharmacology and experimental verification / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To explore the mechanism of fructus lycii in treating dry eye based on network pharmacology and experimental verification.METHODS: Taking “fructus lycii” as key words, the active ingredients and target of fructus lycii were searched by using Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP). Gene targets related to dry eye(DE)were searched by GeneCards and OMIM databases. The target genes of fructus lycii and DE were imported into Venn software to obtain the intersection target map of them. After that, the data were imported into the String database to obtain the PPI protein-protein interaction network diagram. Using Cytoscape3.7.2 software, the PPI protein-protein interaction network diagram was constructed for active ingredients, target sites and related diseases of fructus lycii. The Bioconductor platform and R language were used for gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis. And the key targets in the pathogenesis of DE were verified by experiments.RESULTS: Through TCMSP, 45 types of effective chemical components of fructus lycii, 174 target genes corresponding to active components and 131 common target genes with DE were screenedout. In accordance with the network topology of “drug-composition-disease-target”, 27 main effective components of fructus lycii were found in the treatment of DE. The PPI network was analyzed according to the high degree value, which is the key targets of fructus lycii for DE treatment, mainly including AKT1, VEGFA, CASP3, IL1B, JUN, PTGS2, CXCL8, etc. According to GO enrichment analysis, 166 biological functions and processes of fructus lycii for DE treatment were obtained. KEGG enrichment analysis showed that 31 signaling pathways were involved. Additionally, experimental verification displayed that the protein expressions of AKT1, interleukin-6(IL-6), tumor necrosis factor(TNF-α)and IL-17 in conjunctiva tissue of the DE model group were significantly increased.CONCLUSIONS: Through network pharmacology, this study confirmed that the treatment of DE by fructus lycii is a complex process involving multi-components, multi-targets and multi-pathways, and that the treatment of DE by fructus lycii is mainly regulated by anti-inflammatory and apoptosis-related molecules.

Objective To compare and analyze the disease burden caused by drinking in China in 1990 and 2019. Methods The global disease burden database 2019 was used to analyze the attribution score (PAF), mortality, disability adjusted life year (DALY) and other indicators attributed to drinking in China in 1990 and 2019. The disease burden caused by alcohol consumption was compared between China and the world as well as different social demographic index (SDI) regions. Results From 1990 to 2019, the PAF attributed to drinking increased by 12.85%. The number of deaths attributed to drinking increased to 514 700, and the mortality increased to 36.18/100 000, while the DALY attributed to drinking increased to 17.2651 million person-years, and the DALY rate increased by 5.16%. The disease burden attributed to drinking was higher in men than that in women, and the attributable mortality and DALY rate in the elderly over 70 years old were higher than those in the young. From 1990 to 2019, the attributable disease burden of esophageal cancer was the highest in China, followed by colorectal cancer. Compared with the world and different SDI regions, China had the lowest standardized DALY rate attributed to drinking. Conclusion Drinking is one of the important risk factors for related diseases and cancers in China, and effective intervention measures should be taken for key populations.

Value of glycosylated hemoglobin A1c and apolipoprotein A-1 ratio on predicting outcome of patients with acute coronary syndrome / 中华心血管病杂志

Objective: To investigate the predictive value of glycosylated hemoglobin A1c/apolipoprotein A-1 (HbA1c/ApoA-1) ratio for major adverse cardiovascular events (MACEs) in patients with acute coronary syndrome (ACS). Methods: The present study is a retrospective cohort study. ACS patients who were hospitalized and underwent coronary angiography at Beijing Hospital from March 2017 to March 2019 were enrolled. Baseline information such as sex, age, previous history, Gensini score, HbA1c and ApoA-1 were analyzed. Patients were divided into two groups according to presence or absence of MACEs and the difference on HbA1c/ApoA-1 ratio was compared between the two groups. According to the tertiles of HbA1c/ApoA-1 levels, patients were divided into high (5.87-16.12), medium (4.50-5.83) and low (2.11-4.48) HbA1c/ApoA-1 groups. Cox proportional risk model was used to evaluate the differences in MACEs and all-cause mortality among the three groups. Kaplan-Meier survival analysis was used to compare the differences of MACEs between the various HbA1c/ApoA-1 groups. Results: A total of 366 ACS patients were included in this study. The mean age of the patients was (65.9±10.3) years. There were 59 MACEs and 10 all-cause deaths during the mean of (22.3±4.4) months follow-up. After adjusting for age, systolic blood pressure, history of diabetes and Gensini score, the incidence of MACEs was 2.45 times higher in the high HbA1c/ApoA-1 group than in the low HbA1c/ApoA-1 group (95%CI 1.16-5.18, P=0.019). There was no significant difference in all-cause mortality between the high and low HbA1c/ApoA-1 groups (P=1.000). Kaplan-Meier survival analysis showed that patients in the high HbA1c/ApoA-1 group had the highest risk of MACEs, while patients in the low HbA1c/ApoA-1 group had the lowest risk of MACEs (P<0.01). Spearman rank correlation analysis showed that HbA1/ApoA-1 ratio was positively correlated with Gensini score in ACS patients (r=0.274, P<0.01). Conclusion: High HbA1c/ApoA-1 ratio was an independent risk factor for MACEs in ACS patients. Patients with high HbA1c/ApoA-1 ratio had more severe coronary artery disease lesions. HbA1c/ApoA-1 ratio may be used as a potential risk stratification biomarker for ACS patients, it might be useful for the early identification of high-risk population and for predicting the incidence of MACEs among ACS patients.

Randomized controlled trial(RCT) of oral Chinese patent medicine in the adjuvant treatment of RVGE in children was retrieved from the databases such as CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, EMbase, and Web of Science from database inception to October 22, 2022. The quality of the included RCT was evaluated according to the Cochrane risk-of-bias tool, and the data were analyzed by RevMan 5.4 and Stata 16 software. Sixty-three RCTs were included, with 11 oral Chinese patent medicines involved, including Xingpi Yanger Granules, Weichang'an Pills, Qiuxieling Mixture, Erxieting Granules, and Changyanning Granules/Syrup. The results of the network Meta-analysis showed that in terms of clinical total effective rate, the top 3 optimal interventions were Changyanning Granules/Syrup, Xiaoer Guangpo Zhixie Oral Liquid, and Xiaoer Shuangjie Zhixie Granules combined with conventional western medicine. In terms of the anti-diarrheal time, the top 3 optimal interventions were Shenling Baizhu Granules, Qiuxieling Mixture, and Shuangling Zhixie Oral Liquid combined with conventional western medicine. In terms of the antiemetic time, the top 3 optimal interventions were Changyanning Granules/Syrup, Xingpi Yanger Granules, and Xiaoer Shuangjie Zhixie Granules combined with conventional western medicine. In terms of the antipyretic time, the top 3 optimal interventions were Shenling Baizhu Granules, Xiaoer Shuangjie Zhixie Granules, and Qiuxieling Mixture combined with conventional western medicine. In terms of the negative conversion rate of rotavirus, the top 3 optimal interventions were Xingpi Yanger Granules, Erxieting Granules, and Cangling Zhixie Oral Liquid combined with conventional western medicine. In terms of reducing creatine kinase isoenzyme MB(CK-MB) level, the top 3 optimal interventions were Weichang'an Pills, Xingpi Yanger Granules, and Xiaoer Shuangjie Zhixie Granules combined with conventional western medicine. In terms of adverse reactions, no se-rious adverse reactions were reported in all studies. Oral Chinese patent medicines in the adjuvant treatment of children with RVGE have their own advantages, Specifically, Changyanning Granules/Syrup + conventional western medicine focuses on improving the clinical total effective rate and shortening the antiemetic time, Shenling Baizhu Granules + conventional western medicine on shortening the anti-diarrheal time and antipyretic time, Xingpi Yanger Granules + conventional western medicine on improving the negative conversion rate of rotavirus, and Weichang'an Pills + conventional western medicine on reducing the CK-MB level. Limited by the quantity and quality of literature included in this study, the results need to be verified by high-quality RCT with a larger sample size.

Three-dimensional finite element study on the effects of maxillary anterior two-step retraction and en-masse retraction with clear aligners / 中华口腔医学杂志

Objective: To investigate the effects of two-step retraction and en-masse retraction on tooth movement pattern of anterior teeth and posterior anchorage with clear aligners using three-dimensional finite element analysis. Methods: A finite element model of maxillary first premolar extraction case undergoing clear aligner treatment was established based on maxillofacial cone-beam CT data of a 24-year-old adult male with individual normal occlusion, who visited Department of Oral Surgery, Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine for impacted mandibular third molar in June, 2022. The initial tooth displacement of five anterior retraction protocols (two-step with canine retraction, two-step with incisor bodily retraction, two-step with incisor retraction-overtreatment, en-masse bodily retraction, and en-masse retraction-overtreatment) were evaluated. Results: Two step with canine retraction caused distal tipping of the canine and labial tipping of the incisors (0.18° for central incisor and 0.13° for lateral incisor). Two step with incisor retraction caused mesial tipping of the canine. In two step with bodily retraction protocol, uncontrolled lingual tipping was found in central incisor (0.29°) and lateral incisor (0.32°). In two-step with incisor retraction-overtreatment protocol, the movement pattern of the incisors didn't change, but the inclinations reduced to 0.21° and 0.18°. En-masse retraction caused distal tipping of the canine. In en-masse bodily retraction protocol, uncontrolled lingual tipping was also found in central incisor (0.19°) and lateral incisor (0.27°). In en-masse retraction-overtreatment protocol, the central incisor showed controlled lingual tipping (0.02°) and the lateral incisor showed palatal root movement (0.03° labial inclination). Posterior teeth exhibited mesial tipping in all five protocols. Conclusion: En-masse retraction with incisor overtreatment was beneficial to incisor torque control in clear aligner treatment.

Emerging and comparative genomic analysis of a novel plasmid carrying blaKPC-2 in Citrobacter freundii / 中华预防医学杂志

Objective: To explore the drug resistance mechanism and gene structure characteristics of a carbapenemase-producing novel incompatibility group plasmid pNY2385-KPC from Citrobacter freundii. Methods: A multi-drug resistant strain was obtained from urine samples of patients with fever in the emergency ward of Li Huili Hospital, Ningbo Medical Center. Bacterial species was preliminary identified and finally confirmed by 16S rRNA gene amplification and the average nucleotide identity alignment, respectively. The minimum inhibitory concentrations of the antimicrobial agents were determined by VITEK 2 Compact System. The complete genome sequence was obtained by "third-generation" sequencing methods, and then detailed annotation of gene function and comparative genomic analysis of plasmid structure were carried out by BLASTP/BLASTN, RefSeq, ConservedDomains, ResFinder, Isfinder, etc. Results: The pNY2385-KPC carried by citrobacter freundii NY2385 belonged a novel incompatibility group, and contained blaKPC-2 and conjugative transfer (type Ⅳ secretory system, T4SS) genes, which could induce conjugative transfer. A total of 15 plasmids of the same type as pNY2385-KPC were retrieved by NCBI, which were from Citrobacter freundii, and the rest were from Serratia marcescens, Escherichia coli, Enterobacter cloacae, Klebsiella pneumoniae, Raoultella planticola and other bacteria, and were broad-host-range plasmids. The sequence comparative analysis of all 6 of the novel plasmid from Citrobacter freundii showed that the structure of the novel plasmid had certain conserved property, with Tn6296 variant structure carrying blaKPC-2, and plasmid pCF1807-3 had both repApNY2385-KPC and repAIncX8. Conclusion: The pNY2385-KPC type plasmids in Citrobacter freundii carried blaKPC-2 resistance gene, which were divided into two subtypes: repApNY2385-KPC single replicator and repApNY2385-KPC/repAIncX8 complex replicator, belonging to broad-host-range plasmids. And as a mobile genetic element, the plasmids promote the spread of blaKPC-2.
