Objective@#To explore the association between bedroom light at night (LAN) exposure and body mass index (BMI) in children at 1 year follow up, so as to provide new strategies for obesity prevention.@*Methods@#From December 2021 to May 2022, cluster random sampling was conducted, involving 648 children from two primary schools in Tianchang, Chuzhou City, Anhui Province, China, to assess bedroom LAN exposure of children during sleep. A questionnaire survey and physical examination were carried out in May 2022. Multivariate linear regression was performed to analyze the correlation between bedroom LAN exposure and BMI variable quantity at 1 year follow up (May, 2023).@*Results@#The median intensity of bedroom LAN exposure during the sleep episode was [1.11(0.35,3.24)lx] in children. The proportion of the sample exposed to an average light intensity of ≥3 lx was 27.5%, while 19.0% was exposed to a LAN intensity of ≥5 lx during the sleep episode. In the multivariable linear regression, after adjusting for covariates, including sex, baseline age, sleep duration, family monthly income, and maternal education level, exposure to a 1 h-average post bedtime LAN intensity of ≥3 lx ( β=0.25, 95%CI =0.05-0.44) and LAN≥5 lx ( β=0.34, 95% CI = 0.12-0.55) was associated with a gain of 0.25 and 0.34 kg/m 2, respectively, in the children s BMI at the 1 year follow up ( P < 0.05).@*Conclusions@#A positive correlation was found between bedroom LAN exposure and BMI variable quantity at 1 year follow up in children. Thus, reduced bedroom LAN exposure might be useful for interventions aimed at obesity prevention.

Objective:To investigate the value of CT radiomic model based on analysis of primary gastric cancer and the adipose tissue outside the gastric wall beside cancer in differentiating stage T1-2 from stage T3-4 gastric cancer.Methods:This study was a case-control study. Totally 465 patients with gastric cancer treated in Affiliated People′s Hospital of Jiangsu University from December 2011 to December 2019 were retrospectively collected. According to postoperative pathology, they were divided into 2 groups, one with 150 cases of T1-2 tumors and another with 315 cases of T3-4 tumors. The cases were divided into a training set (326 cases) and a test set (139 cases) by stratified sampling method at 7∶3. There were 104 cases of T1-2 stage and 222 cases of T3-4 stage in the training set, 46 cases of T1-2 stage and 93 cases of T3-4 stage in the test set. The axial CT images in the venous phase during one week before surgery were selected to delineate the region of interest (ROI) at the primary lesion and the extramural gastric adipose tissue adjacent to the cancer areas. The radiomic features of the ROIs were extracted by Pyradiomics software. The least absolute shrinkage and selection operator was used to screen features related to T stage to establish the radiomic models of primary gastric cancer and the adipose tissue outside the gastric wall beside cancer. Independent sample t test or χ2 test were used to compare the differences in clinical features between T1-2 and T3-4 patients in the training set, and the features with statistical significance were combined to establish a clinical model. Two radiomic signatures and clinical features were combined to construct a clinical-radiomics model and generate a nomogram. The area under the receiver operating characteristic curve (AUC) was used to evaluate the efficacy of each model in differentiating stage T1-2 from stage T3-4 gastric cancer. The calibration curve was used to evaluate the consistency between the T stage predicted by the nomogram and the actual T stage of gastric cancer. And the decision curve analysis was used to evaluate the clinical net benefit of treatment guided by the nomogram and by the clinical model. Results:There were significant differences in CT-T stage and CT-N stage between T1-2 and T3-4 patients in the training set ( χ2=10.59, 15.92, P=0.014, 0.001) and the clinical model was established. After screening and dimensionality reduction, the 5 features from primary gastric cancer and the 6 features from the adipose tissue outside the gastric wall beside cancer established the radiomic models respectively. In the training set and the test set, the AUC values of the primary gastric cancer radiomic model were 0.864 (95% CI 0.820-0.908) and 0.836 (95% CI 0.762-0.910), and the adipose tissue outside the gastric wall beside cancer radiomic model were 0.782 (95% CI 0.731-0.833) and 0.784 (95% CI 0.702-0.866). The AUC values of the clinical model were 0.761 (95% CI 0.705-0.817) and 0.758 (95% CI 0.671-0.845), and the nomogram were 0.876 (95% CI 0.835-0.917) and 0.851 (95% CI 0.781-0.921). The calibration curve reflected that there was a high consistency between the T stage predicted by the nomogram and the actual T stage in the training set ( χ2=1.70, P=0.989). And the decision curve showed that at the risk threshold 0.01-0.74, a higher clinical net benefit could be obtained by using a nomogram to guide treatment. Conclusions:The CT radiomics features of primary gastric cancer lesions and the adipose tissue outside the gastric wall beside cancer can effectively distinguish T1-2 from T3-4 gastric cancer, and the combination of CT radiomic features and clinical features can further improve the prediction accuracy.

ObjectiveTo investigate the effect of the sling massage exercise on postpartum pelvic girdle pain (PPGP). MethodsFrom March, 2022 to May, 2023, 56 patients with PPGP in Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine were randomly divided into control group (n = 28) and observation group (n = 28). Both groups received routine physical therapy and healthy education, while the control group received exercise therapy and the observation group received sling massage exercise, for six weeks. They were assessed with Visual Analog Scale (VAS), Pelvic Girdle Questionnaire (PGQ) and active straight leg raise (ASLR) test before and after treatment, and measured resting and contraction thickness of transversus abdominis with ultrasound; and integrated electromyography (iEMG), root mean square (RMS), median frequency (MF) and mean power frequency (MPF) of pelvic floor muscles with surface electromyography. ResultsAfter treatment, the total effective rate was 96.43% in the observation group and 78.57% in the control group (Z = 2.728, P < 0.05). All the indexes improved in both groups (|t| > 2.080, P < 0.05) except resting thickness of transverse abdominis muscle, and improved more in the observation group than in the control group (|t| > 2.161, P < 0.05). ConclusionThe sling massage exercise can alleviate pain, enhance the stability of the core muscle group, and improve load transfer and quality of life, better than exercise therapy.

Objective: To investigate the clinical, imaging, histological, and molecular features and the differential diagnosis of radiation-associated sarcomas of bone and soft tissue. Methods: Forty-six cases of radiation-associated sarcomas of the bone and soft tissue in Beijing Jishuitan Hospital from January 2010 to January 2022 were retrospectively analyzed; and the imaging, histological features and immunophenotype were examined. Results: There were 33 females and 13 males, aged from 18 to 74 years, with a mean of 52 years. The most common site of radiation-associated sarcomas were the limbs and spine (15 cases), followed by the chest (9 cases). The primary diseases included epithelial tumors (15 breast cancer, 6 cervical cancer, and 5 bowel cancer), hematolymphoid tumors, bone and soft tissue tumors and infectious lesions. The latent period of radiation-associated sarcomas ranged from 2-22 years, with an average of 11.6 years. Histopathologically, the morphology was divergent from the primary tumor. The most common malignant tumor type was undifferentiated sarcoma (22 cases), followed by osteosarcoma (16 cases). The immunophenotype of radiation-related sarcoma was almost the same as the corresponding soft tissue sarcoma. Conclusions: Radiation-induced sarcoma has a wide range of primary tumor types and its imaging, morphology and immunohistochemical features are similar to those of the primary sarcoma of bone and soft tissue. Clinical correlation is often recommended for the differential diagnosis.

Objective:To investigate the effects of Tiaogan Lifei Decoction on the level of symptom control in patients with bronchial asthma (asthma) treated with moderate and high dosage inhaled glucocorticoids (ICS).Methods:Randomized double-blind placebo controlled prospective study was used. Totally 90 patients with asthma (liver lung disharmony, wind phlegm blocking collateral syndrome) using moderate and high dosage ICS who met the inclusion criteria from January 2020 to December 2021 in Chaoyang District Hospital of Traditional Chinese Medicine in Beijing were divided into two groups according to random number table method, with 45 cases in each group. On the basis of using the original dosage of ICS, the treatment group used Tiaogan Lifei Decoction, while the control group used Tiaogan Lifei Decoction simulant. The course of treatment was 12 weeks. TCM symptom score of both group before and after the treatment was detected; asthma control test (ACT) was used to assess the effects of asthma on the patients; St George's Hospital Respiratory Questionnaire (SGRQ) was used to assess patients' quality of life; the peak expiratory flow rate (PEF) was measured with a peak expiratory flow meter. 2 ml of venous blood was collected for eosinophil (EOS) detection, and the serum allergen specific IgE level was determined by ELISA. The adverse reactions were observed during the treatment and the clinical efficacy was evaluated.Results:During the test, 3 cases and 2 cases in the treatment group and control group lost prevention respectively. 3 cases in the treatment group and 6 cases in the control group withdrew from the trial because of the aggravation of symptoms and the need to increase the dosage of ICS. The total effective rate in the treatment group was 78.6% (33/42), and that in the control group was 55.8% (24/43), with statistical significance ( χ2=4.98, P=0.026). After treatment, the scores of daily activities, early awakening, control and total scores in the treatment group were higher than those in the control group ( t values were 1.76, 1.99, 2.00, 2.69, respectively, P<0.01 or P<0.05); after treatment, the scores of cough, chest tightness, active wheezing, upset, pharyngeal itch and total score in the treatment group were lower than those in the control group ( t values were -5.89, -6.01, -5.66, -4.27, -6.67, -9.05, respectively, P<0.01); SGRQ score in the treatment group was lower than that of the control group ( t=-7.19, P<0.01). No serious adverse reactions occurred during treatment in the two groups. Conclusion:Tiaogan Lifei Decoction is helpful to improve the symptom control level of asthma patients who are using ICS, and effectively improve the quality of life of patients with asthma of liver lung disharmony and wind phlegm obstructing collaterals syndrome.

Objective:To explore the relationship of infertility-related stress and depression of infertility women, and the effect of coping style and resilience in it.Methods:A cross sectional study was conducted in 230 infertility women who treated with Assisted Reproductive Technology in Reproductive Medical Center of the First Affiliated Hospital of Soochow University using convenience sampling method from April 2020 to April 2021 with self-made general information questionnaire, Fertility Problem Inventory, Simplified Coping Style Questionnaire, 10-item Connor-Davidson Resilience Scale and Patients' Health Questionnaire Depression Scale-9 item. And correlation and effect analysis was conducted.Results:Two hundred and nineteen questionnaires were finally collected, the effective recovery rate was 95.2%(219/230). The score of Fertility Problem Inventory was (136.21 ± 27.38) points, the score of Simplified Coping Style Questionnaire was (34.26 ± 7.66) points, the score of 10-item Connor-Davidson Resilience Scale was (27.50 ± 6.78) points, the score of Patients' Health Questionnaire Depression Scale-9 item was (4.26 ± 3.83) points. Correlation analysis results showed that infertility-related stress of infertility women was positively correlated with negative coping ( r=0.20, P<0.01) and depression ( r=0.26, P<0.01), negative coping was positively correlated with depression ( r=0.23, P<0.01). Effect analysis results showed that negative coping had a partial mediating effect between infertility-related stress and depression, and the mediating effect size was 0.05, accounting for 15.63% of the total effects. Resilience moderated the second half path of the mediation relationship ( β=-0.137, t=-2.11, P<0.05). Conclusions:The infertility-related stress is a positive predictor of depression. Negative coping has a mediating effect between infertility-related stress and depression, and resilience moderates the effect of negative coping on depression.

Objective:To observe any effect of combining low-frequency transcranial magnetic stimulation (rTMS) with interactive virtual scenario training on the recovery of upper limb motor function after a stroke.Methods:Ninety stroke survivors were randomly divided into a pseudo-rTMS group, an rTMS group and a combination group, each of 30. In addition to basic medication, conventional rehabilitation and nursing care, the pseudo-rTMS, rTMS and combination groups received either sham rTMS treatment, 1Hz rTMS or virtual situational interaction along with 1Hz rTMS 5 days a week for 4 weeks. Before and after the 4 weeks their motor evoked potentials, cortical latency and central motor conduction time were measured, and surface electromyography was applied to the affected biceps brachii and triceps brachii. Meanwhile, the National Institutes of Health Stroke Scale, the Fugl-Meyer upper extremity assessment and the modified Barthel index were employed to assess the degree of neurological deficit, upper extremity motor function and ability in the activities of daily living (ADL).Results:After the 4-week intervention, a significant improvement was observed in all of the outcome measurements with all three groups. At that time the average scores of the rTMS group were significantly better than the pseudo-rTMS group′s averages but the average scores of the combination group were significantly better than those of either of the other two groups.Conclusion:Repeated application of low-frequency transcranial magnetic stimulation combined with virtual scenario interactive training can effectively improve the upper limb motor function and ADL performance of stroke survivors, and relieve the symptoms of neurological deficit. The combined therapy is worthy of application in clinical practice.

The coronavirus disease 2019 (COVID-19) pandemic has stimulated tremendous efforts to develop therapeutic agents that target severe acute respiratory syndrome coronavirus 2 to control viral infection. So far, a few small-molecule antiviral drugs, including nirmatrelvir-ritonavir (Paxlovid), remdesivir, and molnupiravir have been marketed for the treatment of COVID-19. Nirmatrelvir-ritonavir has been recommended by the World Health Organization as an early treatment for outpatients with mild-to-moderate COVID-19. However, the existing treatment options have limitations, and effective treatment strategies that are cost-effective and convenient for tackling COVID-19 are still needed. To date, four domestically developed oral anti-COVID-19 drugs have been granted conditional market approval in China. These drugs include azvudine, simnotrelvir-ritonavir (Xiannuoxin), leritrelvir, and mindeudesivir (VV116). Preclinical and clinical studies have explored the efficacy and tolerability of mindeudesivir and supported its early use in mild-to-moderate COVID-19 cases at high risk for progression. In this review, we discuss the most recent findings regarding the pharmacological mechanism and therapeutic effects focusing on mindeudesivir and other small-molecule antiviral agents for COVID-19. These findings will expand our understanding and highlight the potential widespread application of China's homegrown anti-COVID-19 drugs.

Objective:To investigate the association between fasting blood glucose levels and the risk of early vascular aging(EVA).Methods:The basic information, medical history, and laboratory results of 695 individuals who underwent health check-up at the Physical Examination Center of the First People′s Hospital of Changzhou from January 2020 to March 2021 were retrospectively analyzed.Results:A total of 695 healthy individuals were included in the study, among whom there were 249 cases of EVA and 446 cases of non-EVA. Compared to the non-EVA group, the EVA group showed significant differences in age, gender, triglycerides, high density lipoprotein-cholesterol(HDL-C), fasting blood glucose, left brachial-ankle pulse wave velocity(L-baPWV), right brachial-ankle pulse wave velocity(R-baPWV), systolic blood pressure, and diastolic blood pressure(all P<0.01). All participants were divided into three groups( T1, T2, T3) based on fasting blood glucose levels. As fasting blood glucose levels increased, body mass index, total cholesterol, triglycerides, HDL-C, low density lipoprotein-cholesterol, L-baPWV, R-baPWV, systolic blood pressure, diastolic blood pressure, and EVA indicators showed significant differences among the three groups(all P<0.05). Univariate logistic regression analysis showed that age, gender, triglycerides, HDL-C, systolic blood pressure, diastolic blood pressure, and fasting blood glucose levels were significantly associated with the occurrence of EVA(all P<0.05). For the continuous variable of fasting blood glucose, in the regression equations without correction, with preliminary correction, and with full correction of covariates, higher fasting blood glucose levels significantly increased the risk of EVA, with odds ratios( OR) of 2.249, 2.580, and 2.413, respectively(all P<0.001). Compared to the T1 group, the risk of EVA in the T2 group, after no correction, preliminary correction, and full correction of covariates, was 1.881, 2.040, and 1.972, respectively(all P<0.01). The risk of EVA in the T3 group, unadjusted, preliminary adjustment, and full adjustment of covariates, was 3.234, 3.733, and 3.410, respectively(all P<0.001). After adjusting for confounding factors, a linear relationship between fasting blood glucose levels and the occurrence of EVA was observed through smooth curve fitting. Conclusion:Elevated fasting blood glucose may increase the risk of developing EVA.

Objective: To clarify the phenotypes of the newborns with SLC26A4 single-allele mutation in deafness genetic screening and second variant; to analyze the SLC26A4 genotype and hearing phenotype. Methods: 850 newborns born in Beijing from April 2015 to December 2019 were included and there were 468 males and 382 females. They received genetic deafness screening for 9 or 15 variants, with the result of SLC26A4 single-allele mutation. Firstly, three step deafness gene sequencing was adopted in this work, i.e., the first step was "SLC26A4 gene whole exons and splice sites" sequencing; the second step was "SLC26A4 gene promoter, FOXI1 gene and KCNJ10 gene whole exons" sequencing; and the third step was detection for "SLC26A4 gene copy number variation". Secondly, we collected the results of newborn hearing screening for all patients with the second mutation found in the three step test, and conducted audiological examinations, such as acoustic immittance, auditory brainstem response and auditory steady state response. Thirdly, for novel/VUS mutations, we searched the international deafness gene database or software, such as DVD, ClinVar and Mutation Taster, to predict the pathogenicity of mutations according to the ACMG guideline. Lastly, we analyzed the relationship between genotype and phenotype of newborns with SLC26A4 single allele mutation. Results: Among 850 cases, the median age of diagnosis was 4 months. In the first step, 850 cases were sequenced. A total of 32 cases (3.76%, 32/850) of a second variants were detected, including 18 cases (2.12%, 18/850) with identified pathogenic variants; 832 cases were sequenced and 8 cases of KCNJ10 gene missense variants were detected among the second step. No missense mutations in the FOXI1 gene and abnormal SLC26A4 gene promoter were detected; the third step sequencing results were all negative. Genotypes and hearing phenotypes included 18 cases combined with the second clear pathogenic variant, 16 cases (16/18) referred newborn hearing screening and 2 cases (2/18) passed in both ears; degree of hearing loss consisted of 18 profound ears (18/36), 13 severe ears (13/36) and 5 moderate ears (5/36); audiogram patterns comprised 17 high frequency drop ears (17/36), 14 flat ears (14/36), 3 undistinguished ears (3/36), and 2 U shaped ears (2/36); 11 cases underwent imaging examination, all of which were bilateral enlarged vestibular aqueduct. As for 22 cases of other genotypes, all passed neonatal hearing screening and the hearing diagnosis was normal, including 9 cases with VUS or possibly novel benign variants, 8 cases with KCNJ10 double gene heterozygous variants, and 5 cases with double heterozygous variants. Conclusions: The probability of individuals with SLC26A4 single-allele variant who merge with a second pathogenic variant is 2.12%, all of which are SNV, which can provide scientific basis for the genetic diagnosis and genetic counseling of SLC26A4 variants. Those who have merged with second pathogenic variant are all diagnosed with sensorineural hearing loss. Patients with KCNJ10 gene mutations do not manifest hearing loss during the infancy, suggesting the need for further follow-up.

BACKGROUND@#This study aimed to determine the reasons for conversion and elucidate the safety and efficacy of transition to tenofovir alafenamide/emtricitabine/bictegravir sodium (TAF/FTC/BIC) in highly active antiretroviral therapy (HAART)-experienced HIV-infected patients in real-world settings.@*METHODS@#We conducted a retrospective cohort study. The treatment conversion rationales, safety, and effectiveness in 1684 HIV-infected patients with previous HAART experience who switched to TAF/FTC/BIC were evaluated at Beijing Ditan Hospital from September 2021 to Auguest 2022.@*RESULTS@#Regimen simplification (990/1684, 58.79%) was the most common reason for switching, followed by osteoporosis or osteopenia (375/1684, 22.27%), liver dysfunction (231/1684, 13.72%), decline in tenofovir alafenamide/emtricitabine/elvitegravir/cobicistat (TAF/FTC/EVG/c) with food restriction (215/1684, 12.77%), virological failure (116/1684, 6.89%), and renal dysfunction (90/1684, 5.34%). In patients receiving non-nucleotide reverse transcriptase inhibitors (NNRTI)-containing regimens, lipid panel changes 1 year after switching indicated a difference of 3.27 ± 1.10 mmol/L vs . 3.40 ± 1.59 mmol/L in triglyceride ( P  = 0.014), 4.82 ± 0.74 mmol/L vs . 4.88 ± 0.72 mmol/L in total cholesterol ( P  = 0.038), 3.09 ± 0.70 mmol/L vs . 3.18 ± 0.66 mmol/L in low-density lipoprotein ( P  <0.001), and 0.99 ± 0.11 mmol/L vs . 0.95 ± 0.10 mmol/L in high-density lipoprotein ( P  <0.001). Conversely, among patients receiving booster-containing regimens, including TAF/FTC/EVG/c and lopinavir/ritonavir (LPV/r), lipid panel changes presented decreased trends. We also observed an improved trend in viral load suppression, and alanine transaminase (ALT), aspartate transaminase (AST), estimated glomerular filtration rate (eGFR), and serum creatinine levels after the transition ( P  <0.001).@*CONCLUSION@#The transition to TAF/FTC/BIC demonstrated good treatment potency. Furthermore, this study elucidates the motivations behind the adoption of TAF/FTC/BIC in real-world scenarios, providing clinical evidence supporting the stable conversion to TAF/FTC/BIC for HAART-experienced patients.

Objective: To investigate the distribution and characteristics of gene mutations in osteosarcoma, and to analyze the frequency and types of detectable mutations, and to identify potential targets for individualized treatment of osteosarcoma. Methods: The fresh tissue or paraffin-embedded tissue samples of 64 cases of osteosarcoma that were surgically resected or biopsied and then subject to next generation sequencing, were collected from Beijing Jishuitan Hospital, China from November 2018 to December 2021. The tumor DNA was extracted to detect the somatic and germline mutations using targeted sequencing technology. Results: Among the 64 patients, 41 were males and 23 were females. The patient age ranged from 6 to 65 years with a median age of 17 years, including 36 children (under 18 years old) and 28 adults. There were 52 cases of conventional osteosarcoma, 3 cases of telangiectatic osteosarcoma, 7 cases of secondary osteosarcoma, and 2 cases of parosteosarcoma. The detection rate of gene mutations was overall 84.4% (54/64). There were 324 variations in 180 mutated genes, including 125 genes with copy number variations, 109 single nucleotide variants, 83 insertions or deletions, and 7 gene fusions. The most common mutated genes were TP53, VEGFA, CCND3, ATRX, MYC, RB1, PTEN, GLI1, CDK4 and PTPRD. Among them, TP53 had the highest mutation rate (21/64, 32.8%), single nucleotide variant was the main mutation type (14/23, 60.9%), and 2 cases carried the TP53 germline mutation. VEGFA and CCND3 showed copy number amplification simultaneously in 7 cases. Conclusions: The high-frequency mutation of TP53 suggests that it plays an important role in the pathogenesis and development of osteosarcoma. VEGFA, CCND3 and ATRX are mutated genes in osteosarcoma and worthy of further studies. Combination of pathologic diagnosis and next generation sequencing with clinical practice can guide individualized treatment for patients with refractory, recurrent and metastatic osteosarcoma.

Objective: To investigate the influence of sleep fragmentation in infancy and toddler period on emotional and behavioral problems at the age of 6 years. Methods: Using a prospective cohort design, 262 children were extracted from mother-child birth cohort recruited from May 2012 to July 2013 in Renji Hospital, School of Medicine, Shanghai Jiao Tong University. Children's sleep and physical activities were assessed using actigraphy at 6, 12, 18, 24, and 36 months of age, from which the sleep fragmentation index (FI) at each follow-up point was calculated. Children's emotional and behavioral problems at 6 years of age were assessed using the strengths and difficulties questionnaire. Group-based trajectory model was applied to determine sleep FI in infancy and toddler period trajectory groups with Bayesian information criteria being used to determine the best fitting model. Children's emotional and behavioral problems between groups were examined with independent t test and linear regression models, etc. Results: A total of 177 children, with 91 boys and 86 girls, were included in the final analysis and were divided into 2 groups: high FI group (n=30) and low FI group (n=147). Compared with children in the low FI group, those in the high FI group presents with higher total difficulties score and higher hyperactivity or inattention score ((11.0±4.9) vs. (8.9±4.1), (4.9±2.7) vs. (3.7±2.3) scores, t=2.17, 2.23, both P<0.05, respectively), with the differences remaining significant after adjusting for covariates (t=2.08, 2.09, both P<0.05 respectively). Conclusion: High sleep fragmentation in infancy and toddler period is associated with more emotional and behavioral problems, especially hyperactivity or inattention problems, at 6 years of age.

Oral mucositis (OM) is a common complication during hematopoietic stem cell transplantation. When OM occurs, with the destruction of oral mucosal barrier function, the formation of oral bacterial environment is accelerated, which has a negative impact on the life quality and clinical outcomes of patients. OM can be prevented by keeping the oral cavity clean, using the mouthwash properly, and limiting the delivery of cytotoxic drugs to oral tissues. This review describes the research progress on the prevention and local intervention of OM in patients with hematopoietic stem cell transplantation, in order to provide ideas for the selection of clinical intervention and management strategies on OM, and to provide references for exploring effective management methods for OM.

Periodontitis is one of the most common infectious oral diseases, which can cause destruction of periodontal supporting tissues and even tooth mobility and loss. Controlling infection, eliminating inflammation, restoring the physiological shape of periodontal tissues, and meeting functional and aesthetic needs are the main goals of periodontal treatment. When periodontitis develops to a more severe stage, surgical treatment is necessary to handle soft and hard tissues for good treatment results. Since the development of the first Nd:YAG laser dedicated to dental medicine by Myers in 1990, over 30 years of clinical and basic research have shown that lasers have tremendous potential in assisting periodontal surgery. This article summarizes the principles and operational routines of laser-assisted periodontal surgery, aiming to provide clinical reference for diagnosis and treatment.

OBJECTIVE@#To evaluate the effect of transcutaneous acupoint electrical stimulation (TEAS) at Neiguan (PC 6) on general anesthesia under preserving spontaneous breathing in thoracoscopic lobectomy.@*METHODS@#A total of 66 patients of primary lung cancer undergoing thoracoscopic lobectomy were divided to an observation group (33 cases, 1 case discontinued) and a control group (33 cases). In the observation group, TEAS at Neiguan (PC 6) was used 30 min before anesthesia induction till the end of surgery. The surgery time, maximum value of partial pressure of end-tidal carbon dioxide (PETCO2) and minimum value of oxygen saturation (SpO2) of the two groups were recorded. The dosage of propofol, sufentanil, remifentanil and dexmedetomidine were analyzed. Separately, before induction (T0), at the start of surgery (T1), thoracic exploration (T2) and lobectomy (T3), as well as 30 min (T4) and 60 min (T5) after lobectomy, the mean arterial pressure (MAP), heart rate (HR), respiratory rate (RR), serum cortisol (Cor) and norepinephrine (NE) were measured. The time of post anesthesia care unit (PACU) stay, ambulation, flatus, chest drainage and the incidence of nausea and vomiting were compared between the two groups.@*RESULTS@#The maximum value of PETCO2, the dosage of propofol and remifentanil in the observation group were lower than those in the control group (P < 0.05, P < 0.01), the minimum value of SpO2 in the observation group was higher than that of the control group (P < 0.01). At T1-T5, the MAP, HR, serum Cor and NE levels in the observation group were all lower than those in the control group (P < 0.05). The ambulation time, the time for the flatus, chest drainage time, and the incidence of nausea and vomiting in the observation group were all lower than those in the control group (P<0.001, P < 0.01).@*CONCLUSION@#For the general anesthesia under preserving spontaneous breathing in thoracoscopic surgery, TEAS at Neiguan (PC 6) relieves stress response, reduces opioids dosage and promotes postoperative recovery.

Objective: To investigate the clinicopathological features, diagnosis and differential diagnosis of pediatric myofibroma/myofibromatosis of the soft tissue and bone. Methods: All cases of pediatric myofibroma/myofibromatosis of the soft tissue and bone diagnosed between January 2011 and December 2018 were retrieved from the surgical pathology records in the Department of Pathology, Beijing Jishuitan Hospital, Beijing, China. Clinical and radiological data were collected. H&E and immunohistochemistry were used to examine histological and immunophenotypic features and to make the diagnosis and differential diagnosis. The relevant literature was also reviewed. Results: Twenty-eight cases of pediatric myofibroma/myofibromatosis of the soft tissue and bone were respectively collected. The patients' ages ranged from 2 months to 14 years, with a mean age of 7 years. There were 7 females and 21 males. There were 12 cases located in soft tissue, including the finger (n=9), upper arm (n=1) and foot (n=2). There were 14 cases located in the bone of limb, including the femur (n=8), tibia (n=4), clavicle (n=2), fibula (n=2) and radius (n=1). There were 2 cases of myofibromatosis involving multiple bones. Radiology showed lytic lesions in the bone. The proliferation of spindle-shaped myofibroblasts arranged in fascicles with indistinct eosinophilic cytoplasm and bland nuclei, with no pleomorphism and cytological atypia. The characteristic histologic structure was the biphasic nodular growth pattern with cellular and paucicellular regions. The tumors might arrange in a hemangiopericytoma-like pattern. The stroma varied between dense fibrosis and myxoid changes. The reactive new bone formation and inflammatory cell infiltration also existed. Immunohistochemical study showed that the SMA was positive. The surgical resections were performed. One of the patients had tumor recurrence as a result of 11-month follow-up. Conclusions: The pediatric myofibroma/myofibromatosis of the soft tissue and bone is a very rare benign tumor and has a good prognosis. It has a characteristic morphology and its differential diagnosis from other spindle cell tumors could be made with the immunohistochemical analysis.

Objective:To evaluate the influence factors of the peak time in computed tomography (CT) portal venography.Methods:Twenty-eight patients who underwent CT perfusion (CTP) examination in Minhang Hospital Affiliated to Fudan University from October 2020 to December 2021 were retrospectively collected. The CT enhancement time-density curves of the main portal vein trunk and abdominal aorta were obtained at the cross section of the left and right branches of portal vein. The peak time of portal vein and abdominal aorta, the enhanced CT attenuation of the liver and spleen parenchyma enhancement at the peak value of portal vein were measured. Pearson correlation and regression analysis were performed.Results:The peak time of abdominal aorta was (16.39±2.68)s, and portal vein was (27.12±4.65)s. The enhanced CT attenuation of liver and spleen parenchyma were (84.64±20.21)HU and (142.28±25.15)HU, respectively. The peak time of portal vein was positively correlated with the peak time of abdominal aorta ( r=0.825, P<0.001), and there was no statistical correlation with the enhanced CT values of liver and spleen. Multiple linear regression analysis showed that the peak time of abdominal aorta was an independent factor affecting the peak time of portal vein ( b=1.326, t=5.874, P<0.001). The regression equation was the peak time of portal vein=4.185+ 1.451× the peak time of abdominal aorta. The peak time of portal vein in cirrhosis group was (27.78±4.48)s, and that in noncirrhosis group was (26.8±4.81)s, with no significant difference between the two groups ( P=0.614). Conclusions:There was a linear correlation between the peak time of portal vein and the abdominal aorta, and the results could be helpful to optimize the setting of delay time before CT portal venography.
