ABSTRACT
Background Lead is widely distributed. Lead exposure interferes with early life development in zebrafish, but the mechanisms by which lead exposure affects skeletal development and cardiac development are not clear as yet. Objective To investigate the molecular mechanisms of bone development and cardiac development toxicity induced by lead acetate exposure. Methods Zebrafish embryos were exposed to different concentrations of lead acetate (0, 6, 12, 24, and 48 μmol·L−1) for 3 h post-fertilization (3 hpf) until 5 d post-fertilization (5 dpf). The malformation phenotypes of 5 dpf were counted, and the mRNA expressions of spinal development-related genes (bmp2b, bmp4, bmp9, runx2a, runx2b) and heart development-related genes (nkx2.5, myh6, myh7) were detected by quantitative PCR (qPCR). Expressions of genes of development-related regulatory pathways including Wnt/β-catenin pathway (wnt5a, wnt8a, wnt10a, β-catenin) and TGF-β pathway (tgf-β1, tgf-β2) as well as key molecule eph of Eph-Ephrin signaling were analyzed. Results At 5 dpf, the zebrafish in the lead acetate treated groups showed deformed phenotypes including spinal curvature and pericardial sac edema compared to the control group. In the lead acetate groups at 24 and 48 μmol·L−1, the spinal curvature deformity rates reached 26.47% and 71.52% (P<0.01) respectively. The qPCR results revealed that the expression levels of spinal development-related genes bmp2b, bmp4, bmp9, runx2a, and runx2b were downregulated in the 48 μmol·L−1 exposure group compared to the control group by 82.8%, 58.0%, 88.7%, 85.5%, and 69.2%, respectively (P<0.05 or P<0.01); the expression levels of heart development-related genes myh6, myh7, and nkx2.5 were down-regulated by 63.7%, 58.9%, and 55.2%, respectively (P<0.01); the expression levels of wnt8a and β-catenin in the Wnt/β-catenin pathway were down-regulated by 71.5% and 47.3% (P < 0.05 or P < 0.01), respectively; the expression level of tgf- β1 in the TGF-β pathway was down-regulated by 67.5% (P<0.01); the expression level of eph was down-regulated by 86.9% (P<0.01). Conclusion Lead acetate exerts developmental toxic effects on zebrafish heart and bone by down-regulating the expressions of genes related to spinal development and heart development, as well as inhibiting development-related Wnt/β-catenin and TGF-β pathways and Eph-Ephrin signaling, causing malformed phenotypes such as spinal curvature and pericardial sac edema.
ABSTRACT
ObjectiveTo construct the physical activity intervention effect category and framework for college students with mental and behavioral health and functioning problems based on International Classification of Functioning, Disability, and Health (ICF). MethodsThe typical mental and behavioral health and functioning condition of college students were systematically analyzed using ICF. Relevant literatures about the health and functioning outcomes of college students participating in physical activity were retrieved from the databases of PubMed, Web of Science, EBSCO, and CNKI, from the establishment to August 20th, 2022, and reviewed systematically. ResultsTen English literatures were included, involving ten randomized controlled trials with 848 participants aged 15 to 34 years from seven countries, mainly from the journals of rehabilitation science, sports rehabilitation, rehabilitation psychology and health psychology, and were mainly published after 2016. The typical mental and behavioral health and functioning problems of college students mainly focused on stress, anxiety, depression, sleep disorders, learning fatigue, mobile phone addiction, alcohol drinking disorder, sedentary behavior and physical inactivity. Physical activity interventions included Biodanza, Hatha Yoga, Tai Chi, basketball, Baduanjin, cycling, swimming, roller skating, baseball, skill training, stretching exercise, resistance training, and aerobic exercise, etc. The frequency of interventions was mainly a long-term (four to 14 weeks, one to three times per week) program of high-, moderate-, or low-intensity physical activity. The health outcomes included improving cognitive function, relieving stress, anxiety, depression and learning fatigue, reducing negative automatic thinking, enhancing mindfulness, reducing loneliness and deficiency, improving sleep quality, improving upper limb muscle endurance; promoting the development of exercise habits, increasing physical activity participation, improving activity performance and academic performance, reducing sedentary behavior, drinking behavior and problematic mobile phone use; increasing social interaction, improving health perception and psychosocial function, enriching and improving recreation and campus life, and improving the quality of interpersonal relationships, quality of life and well-being. ConclusionA conceptual framework of physical activity participation of college students with mental and behavioral health and functioning problems is constructed using ICF. The typical mental and behavioral health and functioning problems of college students are mainly classified as mental health and functioning problems, behavioral health and functioning problems. The intervention types of physical activity are divided into physical fitness category, skill category, sports category and combination category. Health outcomes can be reflected in three dimensions: physical and mental health, activity and behavioral health, and overall functioning and quality of life.
ABSTRACT
Experimental research on male infertility is critical to the study of the pathogenesis of male infertility and the evaluation of drug therapy. This paper reviewed animal experiments on male infertility in recent years. The experimental models of male infertility mainly include oligoasthenozoospermia （OA），teratozoospermia，azoospermia， and varicocele animal models. The OA animal models are mostly induced by glycosides of Tripterygium wilfordii （GTW）， adenine，hydrocortisone， and radiation，which are mainly chemical means. The animal models of azoospermia were usually constructed by intraperitoneal injection of bissulfonyl alkylating agent busulfan and immersion of scrotum in 43 ℃ water. There are few studies on animal models of teratozoospermia，and the induction methods by GTW and methyl methanesulfonate（MMS） are common. The animal models of varicocele-caused infertility are usually induced by operation. The ligation of the middle division of the left renal vein between the lateral inferior vena cava and the medial spermatic vein has a significant influence on testicular morphology and epididymal sperm quality. Animal experimental studies have shown that classic prescriptions for tonifying the kidney and promoting spermatogenesis represented by Wuzi Yanzongwan and clinical empirical prescriptions by modern research have played a significant role in the treatment of male infertility. The mechanism of tonifying the kidney in the treatment of male infertility mainly focuses on inhibiting spermatogenic cell apoptosis. The kidney-tonifying method can regulate the apoptosis of spermatogenic cells，which provides a new treatment idea and a reliable scientific basis for traditional Chinese medicine in the field of male reproduction.
ABSTRACT
In recent years，with the change in lifestyle and social environment and the increase in pressure in both life and work，male fertility has decreased significantly in China，and the incidence of male infertility has increased year by year，which has brought great challenges to andrologists. Traditional Chinese medicine （TCM） has a definite curative effect in the treatment of male infertility and is widely applied in clinical practice. In order to clarify the role of TCM in different types and each stage of male infertility，the China Association of Chinese Medicine （CACM） invited outstanding young andrologists in the clinic of TCM and western medicine to discuss topics such as idiopathic oligospermia and teratospermia，abnormal semen liquefaction，varicocele，immune infertility，improving success ratio of assisted reproductive technology，and ameliorating depression or anxiety. They conducted in-depth discussions on the advantages，characteristics，disadvantages，diseases responding specifically，and advantageous aspects of TCM treatment. The causes of male infertility and related links of treatment were summarized. Due to the unclear etiology and complex pathogenesis of male infertility，western medicine cannot achieve a good curative effect，while TCM，taking the holistic view as the core，specializes in improving functional diseases and can correspond to multiple targets and factors，with comprehensive treatments such as internal treatment and external treatment. This study summarized the advantageous diseases and advantageous stages of TCM treatment alone and integrated TCM and western medicine treatment and put forward suggestions for the treatment of the diseases by TCM and western medicine in order to promote the therapeutic effects and advantages of TCM among andrologists，increase mutual learning and communication between TCM and western physicians，provide patients with excellent and personalized treatment plans in clinical practice，and improve the curative effect of male infertility and fertility of males in China.
ABSTRACT
Objective:To explore the application effect of the ternary linkage continuation care model based on cognitive balance theory in patients with rheumatoid arthritis (RA), and to provide a reference for the continuation care model of RA patients.Methods:The convenience sampling method was adopted. A total of 72 RA patients who were treated in Huainan First People's Hospital, Anhui Province from January to December 2020 were selected as the research objects, and they were divided into observation group and control group by random number table method with 36 cases in each group. The control group was given regular discharge guidance and health education, and the observation group was given ternary continuous care based on cognitive balance theory on the basis of the control group. The intervention time was 3 months. The fatigue state, pain catastrophe, exercise self-efficacy and hope index was evaluated by the Bristol Rheumatoid Arthritis Fatigue Multi-Dimensional Questionnaire (BRAF-MDQ), the Pain Catastrophic Scale (PCS), the Self-Efficacy for Exercise Chinese version(SEE-C), and the Herth Hope Index Scale-Chinese version (HHI-C) and the results were compared between the two groups before and after the intervention.Results:There was no significant difference in the score of BRAF-MDQ, PCS, SEE-C, HHI-C before the intervention between the two groups( P>0.05). The scores of physical fatigue, life fatigue, cognitive fatigue and emotional fatigue of BRAF-MDQ in the observation group after the intervention were (10.02 ± 0.85), (6.33 ± 0.58), (3.31 ± 0.48), (4.25 ± 0.56) points, respectively, significantly lower than those in the control group (12.97 ± 1.89), (8.94 ± 0.97), (6.55 ± 0.97), (5.92 ± 0.87) points, and the differences were statistically significant ( t values were 8.54-17.96, all P<0.05). The scores of contemplation, exaggeration, and helplessness of PCS in the observation group after the intervention were (5.66 ± 0.43), (4.12 ± 0.36), (3.31 ± 0.41) points, respectively, which were significantly lower than those in the control group (8.41 ± 0.88), (5.74 ± 0.85), (5.52 ± 0.86) points, and the differences were statistically significant ( t=16.85, 10.53, 13.92, all P<0.05). The scores of SEE-C and HHI-C were (60.22 ± 7.89), (37.48 ± 5.79) points in the observation group after the intervention, which were significantly higher than those in the control group (46.98 ± 5.84), (34.21 ± 4.93) points, and the differences were statistically significant ( t=8.09, 2.58, both P<0.05). Conclusions:The ternary linkage continuation nursing model based on the cognitive balance theory has a significant effect on alleviating the fatigue state and pain catastrophe of RA patients, and helps to improve the patients' hope level and exercise self-efficacy.
ABSTRACT
Objective:To summarize the clinical manifestations and gene mutation features of patients with nucleotide excision repair (NER) disorders.Methods:A retrospective analysis was made on clinical data of patients with NER disorders who were admitted to the Chinese People′s Liberation Army General Hospital from October 2008 to February 2022 and diagnosed in the Outpatient Department of Beijing Children′s Hospital, Capital Medical University from October 2015 to February 2022.Literature on previously reported Chinese patients with NER disorders was reviewed.Results:(1)A total of 16 patients with NER disorders were enrolled, including 6 males and 10 females.The onset age was 7.5 (4.0, 12.0) months and the age at diagnosis was 42.0 (21.5, 77.0) months.There were 3 types of NER disorders: Cockayne syndrome (CS) in 13 cases, Xeroderma Pigmentosum (XP) in 2 cases and Cerebro-Oculo-Facio-Skeletal syndrome (COFS) in 1 case.Four disease-causing genes were detected: CSA gene in 11 cases, CSB gene in 3 cases, XPG gene in 1 case, and XPD gene in 1 case.The first symptoms of the 16 patients were photosensitivity and developmental delay, and neurological symptoms were observed in all the 3 NER disorder types.XP and CS patients had skin symptoms.CS patients presented typical facial features, visual and auditory impairment, microcephaly and changes in neuroimaging features.COFS patients showed intrauterine growth retardation.(2)Results of literature review: a total of 96 Chinese patients reported were retrieved, involving 6 disease types, including CS in 45 cases, XP in 44 cases, trichothiodystrophy in 4 cases, COFS in 1 case, XP-CS in 1 case, and ultraviolet sensitive syndrome in 1 case.Nine mutated genes were identified: CSA in 33 cases, XPA in 15 cases, CSB in 13 cases, XPV in 10 cases, XPC in 9 cases, XPG in 7 cases, XPD in 7 cases, XPF in 1 case, and MPLKIP in 1 case.The common symptoms were growth failure (62 cases), skin photosensitivity (61 cases), typical facial features (52 cases), mental retardation (49 cases) and microcephaly (48 cases). Among 36 cases had imaging data 33 cases(91.7%)had calcification of basal nucleus or globus pallidus.Three cases had intrauterine growth retardation and microcephaly during pregnancy.

ABSTRACT
Objective:To re-evaluate the methodological quality, evidence quality and reporting quality of the systematic review and meta analysis of Traditional Chinese Medicine (TCM) in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods:We searched the databases of CNKI, Wanfang, VIP, Cochrane Library, PubMed, EMbase, and retrieved the systematic reviews or meta-analysis literatures on the treatment of AECOPD with TCM from the establishment of the database to February 28, 2021. We applied AMSTAR2 scale and GRADE Tools, PRISMA statement to evaluate methodological quality, evidence quality and report quality.Results:A total of 15 systematic reviews were included, including 85 outcome indicators. The evaluation results of AMSTAR2 scale showed that 9 articles were low-quality methodology and 6 articles were very low-quality methodology. The GRADE results showed that the quality of evidence for 23 outcome indicators was moderate, the quality of evidence for 30 outcome indicators was low, and the quality of evidence for 32 outcome indicators was very low. The results of the PRISMA statement showed that the quality of the reporting is relatively adequate.Conclusion:TCM combined with western medicine can improve the clinical efficacy of AECOPD to a certain extent, but the methodological quality of reviews and the quality of evidence are generally low. In the future, researchers should standardize the writing of systematic reviews/meta-analysis, in order to provide clinicians with more authentic and reliable evidence-based evidence.
ABSTRACT
As an important tool to evaluate cardiac autonomic function, heart rate variability (HRV) is closely associated with ischemic stroke. The change of HRV can not only increase the incidence and recurrence risk of ischemic stroke, but also affect the severity of the disease and the risk of complications, resulting in poor outcomes. Effective intervention for patients with stroke to restore their autonomic nerve function is expected to become a new target for the treatment of ischemic stroke. This article reviews the research progress of the correlation between HRV changes and ischemic stroke.

ABSTRACT
The American Association of Cataract Surgeons issued the Consensus on Astigmatism Management in Cataract Surgery in 2019. To help Chinese ophthalmologists better comprehend the consensus, the main contents are explained: Toric intraocular lens(Toric IOL)implantation is the first choice for correcting corneal astigmatism. Three or more than three instruments should be used for preoperative measurement, and the values that are consistent with results should be taken. Then the Barrett Toric calculator can be used to calculate Toric IOL. When calculating toric IOL,the position of the surgical incision, surgically induced astigmatism(SIA), etc. should be considered. Then, the Toric IOL that makes resultant astigmatism close to 0 without flipping the astigmatism axis can be selected. The intraoperative automated image-guided systems can be used to guide the implantation. If residual astigmatism causes discomfort, laser in situ keratomileusis(LASIK)or IOL replacement can be used for correction. Toric IOL implantation is not recommended for patients with pseudoexfoliation(PXF)syndrome or macular lesions. There are many contraindications in dysfunctional lens syndrome(DLS)patients, which should be carried out by senior doctors. In the future, it is necessary to explore further the influence of haptic design and optic material on the rotational stability of IOL. Cataract surgery assisted by intraoperative aberrometers, automated image-guided systems or femtosecond laser still needs further development.
ABSTRACT
AIM: To quantify the lacrimal punctum using anterior segment optical coherence tomography(AS-OCT)and analyze the correlation between the epiphora and primary punctal stenosis.METHODS: A cross-sectional study. There were 43 healthy volunteers(57 eyes)and 44 patients(62 eyes)with primary lacrimal punctal stenosis and epiphora enrolled in the Lacrimal Center of the Third Medical Center of PLA General Hospital from September 2020 to January 2021. The inferior punctum of all subjects were scanned by AS-OCT, and the images were quantified in order to observe the AS-OCT image features. The outer punctal diameter, punctal depth, tear well diameter and tear well depth were all measured simultaneously. The inferior punctum's punctal reserve and punctal reserve ratio were estimated according to the available parameter data.RESULTS: 1)The measured parameters conforming to normal distribution were expressed as mean±standard deviation. The observation group's outer punctal diameter, tear well diameter, tear well depth, and punctal reserve ratio were 458.19±63.58μm, 200.34±84.69μm, 188.95±87.50μm and 0.32±0.18, respectively, while the control group's outer punctal diameter, tear well diameter, tear well depth and punctal reserve ratio were 655.53±82.62μm, 230.26±107.02μm, 275.30±144.34μm, 0.46±0.23, respectively. The parameters in observation group were all lower than those of control group(P<0.05); 2)Parameter data that did not conform to normal distribution were expressed as medians and quartiles, and the results were as follows: the punctal depth in the observation group was 265.50μm(interquartile range 204.25-328.77)μm and the punctal reserve was 71.53μm(interquartile range 46.12-111.37)μm, respectively, while the punctal depth in the control group was 468.76μm(interquartile range 420.50-588.88)μm and the punctal reserve was 182.16μm(interquartile range 131.36-309.84)μm. This difference was statistically significant(P<0.05); 3)In the observation group, there was a negative correlation between the epiphora and the outer punctal diameter(r=-0.448, P<0.05), a positive correlation between the epiphora and tear well depth(r=0.335, P<0.05), and a negative correlation between the epiphora and the punctal reserve and punctal reserve ratio coefficient(r=-0.520, -0.566, P<0.05).CONCLUSION: The AS-OCT can aid in enhancing punctal morphology cognition; The outer punctal diameter and tear well depth are related to the epiphora; The primary punctal stenosis patients with smaller outer punctal diameters are more likely to have the symptom of epiphora, and in patients with punctal stenosis, the greater the potential capacity of the punctum to hold tears, the lesser the degree of epiphora.

Conclusions:7 500 - 9 999 steps/d are optimal walking exercise intensity, it can effectively improve the nutritional status and reduce fatigue of patients with esophageal cancer during concurrent chemoradiotherapy.
ABSTRACT
Acute leukemia (AL) is the most common tumor in childhood.With the improvement of risk stratification therapy, the complete remission rate of AL has been significantly improved.However, central nervous system leukemia (CNSL) remains the major cause of recurrence and death of leukemia.This study aims to review the pathogenesis, diagnosis and treatment of CNSL in children, hoping to further improve the understanding.
ABSTRACT
Cognitive impairment seriously affects the quality of life of patients. Clinically, it is common in cerebral ischemia, sepsis and postoperative. Its etiology includes abnormal expression of regulatory molecules in the brain, ischemic injury of brain tissue and abnormal expression of genes and proteins in brain tissues. However, there is no effective treatment at present. Electroacupuncture has a certain effect on cognitive impairment. Its mechanism mainly includes inhibiting oxidative stress response, enhancing synaptic plasticity, inhibiting neuroinflammation, regulating glial cell activity, regulating excitatory amino acids, and improving glucose metabolism.
ABSTRACT
Purpose@#Nonalcoholic fatty liver disease (NAFLD) is closely associated with metabolic diseases, including obesity and diabetes, and has gradually become the most common cause of chronic liver disease. We investigated the effects of sodium glucose cotransporter 2 (SGLT2) inhibitor canagliflozin on NAFLD in high-fat diet (HFD)-induced obese mice and possible underlying mechanisms. @*Materials and Methods@#Male C57BL/6 mice were fed a normal-diet, HFD, or HFD with canagliflozin for 14 weeks. AML-12 hepatocytes were treated with canagliflozin. Expression of related pathways was assessed. @*Results@#Canagliflozin administration reduced body weight and fat mass, compared with HFD alone. Canagliflozin improved glucose and lipid metabolic disorders. Compared with HFD-fed mice, liver weight, serum alanine transaminase (ALT) levels, and hepatic lipid accumulation were decreased after canagliflozin administration. Additionally, canagliflozin upregulated lipolysis markers (CPT1a, ACOX1, and ACADM), downregulated lipogenesis markers (SREBP-1c and FASN), and suppressed the production of inflammatory cytokines (TNFα, MCP1, IL-1β, and IL-6), consistent with significantly increased LC3 II/I and Atg7 levels in the liver following canagliflozin treatment. In vitro, canagliflozin increased CPT1a, ACOX1, and ACADM expression, decreased SREBP-1c and FASN protein expression, and reduced TNFα, MCP1, IL-1β, and IL-6 mRNA levels in lipid mixture (LM)-induced hepatocytes in a dose-dependent manner. These changes were reversed by 3-MA, an autophagy inhibitor. @*Conclusion@#Our findings suggest that canagliflozin ameliorates the pathogenesis of NAFLD by regulating lipid metabolism and inhibiting inflammation, which may be associated with its promotion of autophagy.
ABSTRACT
Objective@#: To evaluate the safety and efficacy of an overlapped stenting-assisted coiling technique in treating vertebral artery dissecting aneurysm (VADA) via Low-profile Visualized Intraluminal Support (LVIS) stent-within-Neuroform EZ stent. @*Methods@#: From January 2017 to June 2019, 18 consecutive patients with VADAs (ruptured : unruptured=5 : 13) were treated with the overlapping stents assisted-coiling technique in our center. The overlapping manner was a Neuroform EZ stent being deployed first, followed by LVIS stents placement using the ‘shelf’ technique. The patients’ clinical characteristics, technical feasibility and safety, and immediate and follow-up angiographic results were retrospectively reviewed. @*Results@#: Seventeen (94.4%) procedures were technically successful with an exact deployment of the stents and patent parent or perforator arteries. The immediate angiographies after procedure confirmed Raymond class I, II, and III occlusion of VADAs were in 12 (66.7%), two (11.1%), and four cases (22.2%), respectively. Post-procedural complications developed in one patient (5.6%) with minor brainstem infarctions, which resulted from an in-stent thrombosis during the procedure. Angiographic follow-up at 5.7 months (range 3 to 9 months) demonstrated Raymond class I and II occlusion were in all cases (100%). The modified Rankin Scale scores at 21.3 months (range 15 to 42 months) 0–2 in 17 cases (94.4%) and three in one case (5.6%). @*Conclusion@#: Overlapping stents via LVIS stent-within-Neuroform EZ stent combined with coiling is safe and effective for patients with VADA in the midterm results.
ABSTRACT
Purpose@#Neoadjuvant chemotherapy (NAC) is widely used to treat breast cancer (BC). The prediction and evaluation of chemotherapy responses remains a significant challenge. @*Methods@#MicroRNAs (miRNAs) play a crucial role in cancer drug resistance. We used a miRNA microarray and identified that miR-638 is downregulated in chemoresistant cases.However, the exact role of miR-638 and the underlying mechanisms of chemoresistance remain unclear. Using real-time quantitative reverse transcription polymerase chain reaction, we found significant downregulation of miR-638 in chemoresistant patients compared with chemosensitive patients. To explore the function of miR-638, we overexpressed and inhibited miR-638 expression in MDA-MB-231 and MCF-7 cells by transfecting them with miR-638 mimics and miR-638 inhibitor, respectively. Cell proliferation and apoptosis were measured using MTS and flow cytometry, respectively. A minimal patient-derived xenograft (MiniPDX™) model was established to evaluate the chemosensitivity to different drugs. @*Results@#The results showed that cell proliferation decreased and cell apoptosis increased in cells transfected with the miR-638 mimic, and cell proliferation and apoptosis were reversed with transfection of miR-638 inhibitor compared with the control group. Among patients who received 5-fluorouracil (5-FU), miR-638 expression levels were lower in the chemoresistant group than in the chemosensitive group. The MiniPDX™ model showed that MDA-MB-231 cells overexpressing miR-638 were more susceptible to 5-FU treatment in vivo. @*Conclusion@#We provided evidence of acquired resistance to 5-FU caused by miR-638 deficiency. Alterations in miR-638 may be used with 5-FU chemotherapy during NAC for BC.
ABSTRACT
ObjectiveTo analyze drug resistance status and risk factors in elderly tuberculosis patients in Ninghai County of Zhejiang Province， and to provide basis for prevention and control of drug-resistant tuberculosis. MethodsClinical data were collected from 142 elderly tuberculosis patients （with positive sputum culture） who were diagnosed and treated in medical institutions in Ninghai from 2016 to 2020. The risk factors of drug resistance were analyzed by Chi-square test and logistic regression model. ResultsThe overall drug resistance rate was 33.80%， and the drug resistance rate in patients with recurrent pulmonary tuberculosis was significantly higher than that in patients with initial pulmonary tuberculosis， and the difference was statistically significant. Multivariate unconditional logisitic regression analysis showed that irregular medication and disease recurrence were independent risk factors for multidrug resistance in the elderly patients. ConclusionThe drug resistance rate in elderly tuberculosis patients in Ninghai is high. It is necessary to strengthen the management and supervision of tuberculosis in the community， and to carry out effective health education and visit for elderly patients， especially for newly treated patients， and to avoid treatment failure caused by irregular medication and interruption of treatment.
ABSTRACT
We intend to study the structural characteristics of Lycopus europaeus Linn. chloroplast genome and compare the evolutionary relationship of species from Lamiaceae with similar medicinal effects. The total DNA of Lycopus europaeus was sequenced using the Illumina Hiseq 4000 Sequencing platform and was assembled using NOVOplasty software. And then we annotated and analyzed the genome using the CPGAVAS2 online tool. We constructed the phylogenetic tree using the Stellera chamaejasme and Potentilla chinensis as the outgroup. The whole length of Lycopus europaeus chloroplast genome was 152 085 bp. A total of 132 genes were annotated including 88 protein-coding genes, 8 rRNA genes and 36 tRNA genes. Among them, 8 protein-coding genes (ndhB, rps7, rps12, rps19, rpl2, rpl23, ycf2, ycf15), 7 tRNA coding genes (trnM-CAU, trnL CAA, trnN-GUU, trnE-UUC, trnV-GAC, trnA-UGC, trnR-ACG) and 4 rRNA coding genes (rrn16s, rrn23s, rrn4.5s, rrn5s) are located in the IR region. There are 13 protein coding genes [rps16, rps19 (×2), atpF, rpoC1, rpl2 (×2), petB, petD, rpl16, ndhB (×2), ndhA] each contains one intron, two protein-coding genes (ycf3, clpP) each contain two introns, and 8 tRNA coding genes each contain one intron. A total of 34 SSRs were detected in the chloroplast genome of Lycopus europaeus. Phylogenetic analysis revealed that two species in the Lycopus genus, four species in the Dracocephalum genus, Glechoma longituba, two species in the Mentha genus and Prunella vulgari, in total 10 species are most related. The complete genome sequence of Lycopus europaeus was obtained and analyzed, which clarified the evolutional relationship between the species of Lycopus europaeus and in the Lamiaceae family.
ABSTRACT
Objective: To investigate the feasibility, safety and efficacy of transoral robotic surgery (TORS) in the treatment of lingual thyroglossal duct cyst (LTGDC). Methods: The clinical data of 10 patients with LTGDC treated with TORS in Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology from May 2017 to November 2020 were analyzed retrospectively,including 6 males and 4 females, aged 5-44 years. The cysts were fully exposed, and resection usually started from the cephalic side of lesions. The range of resection was 3 to 5 mm away from the lesions, and partial hyoid bone was removed if necessary. Intra-operative robotic set-up time,operation time and estimated blood loss,and post-operative local bleeding, dyspnea and recovery time for oral intake were analyzed. SPSS 12.0 software was used for statistical analysis. Results: The cysts in all 10 patients were successfully resected by TORS with da Vinci Si surgical system. The mean robotic set-up and exposure time, operation time, estimated intraoperative blood loss and recovery time for oral intake were (15.5±7.1) min, (17.6±7.4) min, (8.9±6.4)ml and (2.3±2.2)days, respectively. No patient required tracheostomy intra-or post-operatively, and no symptoms of airway obstruction, postoperative bleeding, pharyngeal fistula, hoarseness and neurological impairment occurred after operation. The patients were followed up for 5 to 47 months, with median follow-up time of 17 months, and no recurrence was observed. Conclusion: TORS is safe and feasible for resection of LTGDC, with rapid recovery and low recurrence rate.
