Objective: To explore the role of outdoor activity in the relationship between infancy responsive caregiving trajectories and early childhood development, so as to provide a theoretical basis for the promotion of early child development. Methods: The study participants were drawn from the Shanghai Maternal-Child Pairs Cohort and 4 723 mother-child pairs who completed responsive caregiving questionnaires at 2, 6 and 12 months old were included. Questionnaires were used to assess children s responsive caregiving and average daily hours of outdoor activity at 2 years of age. The Age-Stage Questionnaire, Third Edition (ASQ-3) was used to evaluate children s development problems at 2-5 years old. Group based trajectory model was applied to fit infancy responsive caregiving trajectory. Modified Poisson regression was used to analyze associations between different responsive caregiving trajectory groups and child development, and moderating effects were tested for hours of outdoor activity. Results: Infancy responsive caregiving trajectories were categorized into general group ( n =3 871), declining group( n =160), and fluctuating group( n =646). After adjusting for confounding factors, such as parents educational level, annual household income, maternal progestation body mass index,maternal tobacco exposure during pregnancy,maternal anxiety and depression during pregnancy, maternal age at delivery,maternal gestational age,maternal mode of delivery, children s gender,children s birth weight, and duration of breastfeeding, the results of modified Poission regression analysis showed that compared with the general group, children at the age of 2 in declining and fluctuating group had increased risks of suspected developmental delays in communication, gross motor, fine motor, problem solving, and personal-social scales ( OR =1.41,1.31,1.35,1.23,1.21；1.07,1.08,1.08,1.09,1.06);but children only had increased risk of suspected developmental delays in communication of declining group ( OR =1.08), personal-social scales of fluctuating group ( OR =1.06) at 3-5 years of age ( P <0.05). At lower levels of outdoor activity, children in fluctuating group had reduced scores in communication ( β =-1.41), fine motor ( β =-2.34), problem solving ( β =-1.11) and personal-social scales ( β =-1.99) as compared to general group; and children in declining group had reduced scores in gross motor ( β =-4.78)( P <0.05). While at higher levels of outdoor activity, no differences were found between children in fluctuating, declining groups and those in general group in scores of different scales ( P >0.05). Conclusion Prolonged outdoor activity attenuates the adverse effects of declining and fluctuating trajectories of infancy responsive caregiving on early childhood development.

Objective To analyze the efficacy and safety of unilateral laminectomy and bilateral decompression under unilateral biportal endoscopy(UBE)and microendoscope(MED)in lumbar spinal stenosis.Methods 80 patients with lumbar spinal stenosis from January 2021 to December 2022 were selected and divided into two groups by numerical table method,the control group and the study group,and the number of cases was 40.The grouping method was random number table method.The control group was treated with unilateral laminectomy and bilateral decompression under MED,while the study group was treated with unilateral laminectomy and bilateral decompression under UBE.Operation time,intraoperative blood loss,Oswestry disability index(ODI)and visual analogue scale(VAS)of lumbago and leg pain were obtained before surgery,1,3 months after surgery and at the last follow-up,efficacy and complications were compared between the two groups.Result There were no significant differences in operative time and blood loss between the study group and the control group(P>0.05).1,3 months after surgery and at the last follow-up,ODI in both groups were lower than those before surgery(P<0.05),but there was no difference between the study group and the control group(P>0.05).The VAS of lumbago and leg pain in both groups were lower than those before surgery(P<0.05),at 1,3 months after surgery and the last follow-up,and the study group was significantly lower than the control group(P<0.05).The excellent and good rate of clinical treatment in the study group was 97.50%,and there was no difference compared with 92.50%in the control group(P>0.05).The complication rate of the study group was 2.50%,significantly lower than that of the control group(15.00%)(P<0.05).Conclusion Unilateral laminectomy and bilateral decompression under the UBE and MED have similar efficacy in the treatment of lumbar spinal stenosis,both of which can effectively promote functional recovery,but UBE can reduce pain more effectively and has fewer postoperative complications.

Objective To investigate the effect of Ganoderma lucidum polysaccharide peptide(GLPP)on proliferation,migration and apoptosis of diffuse large B cell lymphoma(DLBCL)cells and its mechanism.Methods OCI-LY19 cells were divided into six groups:control,GLPP,si-NC,si-protein arginine methyltransferase 6(PRMT6),GLPP+pcDNA3.1-NC and GLPP+pcDNA3.1-PRMT6 groups.The si-NC,si-PRMT6,GLPP+pcDNA3.1-NC and GLPP+pcDNA3.1-PRMT6 groups were transfected with si-NC,si-PRMT6,pcDNA3.1-NC and pcDNA3.1-PRMT6,respectively.After the transfection was completed,control,si-NC and si-PRMT6 groups were treated with RPMI-1640 medium,while the GLPP,GLPP+pcDNA3.1-NC and GLPP+pcDNA3.1-PRMT6 groups were cultured with RPMI-1640 medium containing with 20 μg·mL-1 GLPP.After administration 24 h,the cell proliferation inhibition rates,mobility rates and apoptosis rates were detected.The expression levels of PRMT6 protein were measured by Western blotting.Results The cell proliferation inhibition rates of si-NC,si-PRMT6,GLPP+pcDNA3.1-NC and GLPP+pcDNA3.1-PRMT6 groups were(1.28±0.16)％,(38.61±3.29)％,(52.84±7.74)％and(22.75±3.87)％,respectively.The number of cell migrations in the control,GLPP,si-NC,si-PRMT6,GLPP+pcDNA3.1-NC and GLPP+pcDNA3.1-PRMT6 groups was(252.65±24.65),(136.54±16.46),(231.65±21.24),(142.76±15.34),(140.23±9.84)and(192.38±23.38)cells;the apoptosis rates were(4.36±0.52)％,(28.24±2.36)％,(4.23±0.45)％,(24.54±2.27)％,(28.42±3.85)％and(14.25±2.13)％);the expression levels of PRMT6 protein were 1.82±0.21,0.56±0.05,1.78±0.19,0.54±0.05,0.29±0.02 and 0.32±0.03,respectively.The differences of above indexes were statistically significant between control group and GLPP group,between si-NC group and si-PRMT6 group,between GLPP+pcDNA3.1-NC group and GLPP+pcDNA3.1-PRMT6 group(all P＜0.05).Conclusion GLPP could inhibit proliferation,migration and promote apoptosis of DLBCL cells by down-regulating PRMT6 expression.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.

Objective To analyze the application effect and economic benefit of total parathyroidectomy(TPTX)+subcutaneous implantation of forearm(AT)+thymectomy in patients with secondary hyperparathyroidism(SHPT).Methods The clinical data of 110 patients with SHPT who were treated in our hospital from March 2018 to January 2021 were retrospectively analyzed.They were divided into medication group(50 cases,receiving cinacalcet combined with low-dose calcitriol)and operation group(60 cases,receiving TPTX+AT+thymectomy)according to different treatment regimens.The biochemical indexes,cardiac structure and function,clinical symptoms and quality of life of the two groups were compared before and after treatment for 24 months,and the complications,cost-effectiveness and recurrence rate of the two groups after operation were counted.Results After treatment,the levels of serum iPTH[(206.45±152.59)pg/ml],calcium[(2.05±0.26)mmol/L],phosphorus[(1.48±0.21)mmol/L],calcium-phosphorus product(3.02±0.69)and ALP[(102.03±30.25)U/L]in operation group were all lower Drug group[(721.32±325.36)pg/ml,(2.22±0.18)mmol/L,(1.91±0.22)mmol/L,(4.22±0.74),(140.62±27.15)U/L](P＜0.05);LVEF[(60.85±4.02)％]in operation group was higher than that in drug group[(55.58±3.84)％].LVED[(48.03±2.58)mm]and LVST[(9.85±0.76)mm]were lower than those in drug group[(51.02±3.65)mm,(11.12±0.86)mm](P＜0.05).The scores of bone pain,skin pruritus and restless legs syndrome in the operation group were lower than those of the medication group,and the KDTA score was higher than that of the medication group(P＜0.05).The total cost of treatment in the operation group[(4.06±1.42)million yuan]was not significantly different from that in the drug group[(3.46±1.85)million yuan](P＞0.05).The effective rate of iPTH reduction in operation group was 90.00％(54/60),which was higher than that in drug group(48.00％,24/50)(P＜0.05).The cost-effectiveness analysis showed that the CER of the drug group and the operation group were 7.21 and 4.51 respectively,and the operation treatment had more cost-effectiveness advantages.The incremental cost-effectiveness analysis shows that compared with the drug group,the operation group needs to increase the cost by 14,800 yuan for each additional patient effectively treated for SHPT(P＞0.05).There was no significant difference in the incidence of complications(13.33％VS 12.00％)and the recurrence rate(8.33％VS 4.00％)at 2 4 months after treatment between the operation group and the drug group(P＞0.0 5).Conclusion TPTX+AT+thymectomy can relieve the bone pain,reduce the iPTH level,correct the disorder of calcium and phosphorus metabolism,improve the heart function and structure,and improve the quality of life,and the cost-effectiveness is higher than SHPT of drug treatment,without increasing short-term recurrence rate.

Objective To investigated the correlation between the effects of the compatibility of fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle on chemical composition and anti-inflammatory effects.Methods An HPLC-DAD method was employed for the simultaneous determination of various components of fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle,including paeoniflorin,albiflorin,benzoylpaeoniflorin,oxypaeoniflorin,glycyrrhizic acid and glycyrrhizin.An adjuvant-induced arthritis rat model was established.Administration groups were given fried Paeoniae Radix Alba,Glycyrrhizae Radix et Rhizoma Praeparata cum Melle,and fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle liquid by gavage for 2 weeks,respectively.Enzyme-linked immunosorbent assay was conducted to detect the levels of inflammatory factors IL-1β,TNF-α and PGE2 in serum of each group.Factorial design,bivariate correlation analysis,and multiple linear regression were employed to explore the effect of compatibility on chemical composition and its correlation with anti-inflammatory efficacy.Results The established HPLC-DAD analysis method revealed a significant increase in the content of oxypaeoniflorin,albiflorin and benzoylpaeoniflorin following the compatibility of fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle(P<0.05).Compared with the model group,the contents of IL-1β,TNF-α and PGE2 in serum of each administration group decreased(P<0.01),and the contents of IL-1β,TNF-α and PGE2 in serum of compatibility group were lower than fried Paeoniae Radix Alba group and Glycyrrhizae Radix et Rhizoma Praeparata cum Melle group(P<0.05,P<0.01).The results from the factorial design indicated the presence of an interaction effect between fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle.Bivariate correlation analysis results showed negative correlations between oxypaeoniflorin,albiflorin,paeoniflorin,glycyrrhizin,benzoylpaeoniflorin and glycyrrhizic acid with the contents of IL-1β,TNF-α and PGE2,respectively.Multiple linear regression results revealed that glycyrrhizin and glycyrrhizic acid were negatively correlated with the contents of IL-1β,TNF-α and PGE2.Conclusion The established method for analyzing multiple constituents in the compatibility of fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle is straightforward,rapid,highly specific,accurate,and reliable,suitable for quality evaluation and control.The compatibility of fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle can inhibit the expressions of IIL-1β,TNF-α and PGE2,and the content of chemical composition is correlated with anti-inflammatory effects.

Infectious diseases are the leading cause of death in children. Sepsis is a critical infectious disease that causes death in children globally, with a high morbidity and mortality rate. It poses a serious threat to children′s health. Early diagnosis has become the key to treating severe sepsis. The establishment of animal models of sepsis can help people better diagnose sepsis and take interventions to improve the prognosis of sepsis patients. This study reviews the types, advantages and disadvantages of existing animal models of sepsis and proposes the optimization of these models to provide a reference basis for the selection and optimization of experimental models and the promotion of the "reverse transformation" of sepsis into clinical practice.

Objective To evaluate the improvement in the quality of early postoperative recovery in patients undergoing cardiac valve surgery with remimazolam-based fast-track anesthesia,and to provide a reference for the clinical optimization of fast-track anesthesia and Enhanced Recovery After Surgery(ERAS)protocols.Methods We selected elective surgery patients undergoing median sternotomy for cardiac valve replacement and/or repair under general anesthesia with extracorporeal circulation.Based on routine anesthesia assessment and fast-track anesthesia suitability assessment,a total of 228 patients were strictly enrolled according to the inclusion and exclusion criteria and randomly divided into two groups:the Remimazolam group(n=114)and the Propofol group(n=114).Patients in the Remimazolam group were induced and maintained with remimazolam for anesthesia,while patients in the control group were administered propofol.We recorded the general information and surgical data of the patients;the QoR-15 scores before surgery(1 day preoperatively),1 day postoperatively,3 days postoperatively,and 1 day before discharge;as well as hemodynamic parameters at key time points after admission,the incidence of hypotension and bradycardia after anesthesia,the duration of surgery,anesthesia duration,postoperative mechanical ventilation time,ICU stay,postoperative hospital stay,and the incidence of perioperative cardiovascular adverse events and the incidence of early postoperative complications.Results There was no statistically significant difference in general data and QoR-15 scores between the two groups 1 day before surgery(P>0.05).The QoR-15 score of the Remima-zolam group 1 day before discharge was higher than that of the Propofol group,with a statistically significant differ-ence(P<0.05),but the difference was less than the minimum clinically important difference,which is less than 8,indicating no significant clinical benefit.One minute after intubation and one minute after skin incision,the heart rate in the Propofol group slowed down and the Mean Arterial Pressure(MAP)significantly decreased,with a statis-tically significant difference between the groups(P<0.05);there was no statistically significant difference in heart rate and MAP at other times.The incidence of intraoperative hypotension and bradycardia was lower in the Remima-zolam group than in the Propofol group,with a statistically significant difference(P<0.05).The duration of postop-erative mechanical ventilation,ICU stay,postoperative hospital stay,and the rate of re-intubation were all shorter in the Remimazolam group than in the Propofol group,and the success rate of fast-track anesthesia was higher in the Remimazolam group,with a statistically significant difference(P<0.05).There was no statistically significant difference in the incidence of perioperative complications between the two groups.Conclusions Compared with the commonly used intravenous anesthetic propofol,the remimazolam-based fast-track anesthesia regimen did not signifi-cantly improve the postoperative recovery quality scores in patients undergoing cardiac valve surgery.However,remimazolam had advantages in maintaining hemodynamic stability,increasing the success rate of fast-track anesthe-sia,shortening postoperative ICU stay and hospital stay,and is a viable intravenous anesthetic option for cardiac surgery patients.

Background::Endometriosis (EM) is a complex benign gynecological disease, but it has malignant biological behavior and can invade any part of the body. Clinical manifestations include pelvic pain, dysmenorrhea, infertility, pelvic nodules, and masses. Our previous study successfully detected circulating endometrial cells (CECs) in the peripheral blood of patients with EM. The purpose of this study is to overcome the limitation of cell size in the previous microfluidic chip method, to further accurately capture CECs, understand the characteristics of these cells, and explore the relationship between CECs and the clinical course characteristics of patients with EM.Methods::Human peripheral venous blood used to detect CECs and circulating vascular endothelial cells (CVECs) was taken from EM patients ( n = 34) hospitalized in the Peking University People’s Hospital. We used the subtraction enrichment and immunostaining fluorescence in situ hybridization (SE-iFISH) method to exclude the interference of red blood cells, white blood cells, and CVECs, so as to accurately capture the CECs in the peripheral blood of patients with EM. Then we clarified the size and ploidy number of chromosome 8 of CECs, and a second grouping of patients was performed based on clinical characteristics to determine the relationship between CECs and clinical course characteristics. Results::The peripheral blood of 34 EM patients and 12 non-EM patients was evaluated by SE-iFISH. Overall, 34 eligible EM patients were enrolled. The results showed that the detection rates of CECs were 58.8% in EM patients and 16.7% in the control group. However, after classification according to clinical characteristics, more CECs could be detected in the peripheral blood of patients with rapidly progressive EM, with a detection rate of 94.4% (17/18). In total, 63.5% (40/63) of these cells were small cells with diameters below 5 μm, and 44.4% (28/63) were aneuploid cells. No significant association was found between the number of CECs and EM stage.Conclusion::The number and characteristics of CECs are related to the clinical course characteristics of patients with EM, such as pain and changes in lesion size, and may be used as biomarkers for personalized treatment and management of EM in the future.
