Objective To investigate the relevancy between diet and colostrum nutrition in pregnant women in the second and third trimesters.Methods A total of 378 pregnant women who met the inclusion and exclusion criteria and were registered in the Obstetrics and Gynecology Hospital,Fudan University from Jun 2022 to Apr 2023 were included in the study by continuous sampling method.General information,diet in the second trimester,diet in the third trimester and colostrum data 48-72 h after delivery were collected.The relevancy between daily dietary nutrient intake and colostrum quality in pregnant women during the second and third trimesters was analyzed.Results All of the 378 subjects met the colostrum collecting criteria.We found that dietary fat intake during the second trimester was positively correlated with colostrum quality(OR=2.408,95%CI:1.086-5.338),and energy was negatively correlated with colostrum quality(OR=0.319,95%CI:0.157-0.651).Dietary protein intake in the third trimester was positively correlated with colostrum quality(OR=5.905,95%CI:1.757-19.842).Conclusion There is a certain relevancy between diet and colostrum nutrition.A reasonable diet during pregnancy is recommended to promote the quality of colostrum.

Purpose: This study was conducted to evaluate the efficacy of bladder outlet surgery in patients with detrusor underactivity (DU) and to identify factors associated with successful outcomes. Methods: We conducted a retrospective review of men diagnosed with DU in urodynamic studies who underwent bladder outlet surgery for lower urinary tract symptoms between May 2018 and April 2023. The International Prostate Symptom Score (IPSS) questionnaire, uroflowmetry (UFM), and multichannel urodynamic studies were administered. Successful treatment outcomes were defined as either an IPSS improvement of at least 50% or the regaining of spontaneous voiding in patients urethral catheterization prior to surgery. Results: The study included 93 male patients. Men diagnosed with significant or equivocal bladder outlet obstruction (BOO) experienced significant postoperative improvements in IPSS (from 20.6 to 6.0 and from 17.4 to 6.5, respectively), maximum urine flow rate (from 5.0 mL/sec to 14.4 mL/sec and from 8.8 mL/sec to 12.2 mL/sec, respectively) and voiding efficiency (from 48.8% to 86.0% and from 61.2% to 85.1%, respectively). However, in the group without obstruction, the improvements in IPSS and UFM results were not significant. The presence of detrusor overactivity (odds ratio [OR], 3.152; P=0.025) and preoperative urinary catheterization (OR, 2.756; P=0.040) were associated with favorable treatment outcomes. Conversely, an unobstructed bladder outlet was identified as a negative prognostic factor. Conclusions In men with DU accompanied by equivocal or significant BOO, surgical intervention to alleviate the obstruction may enhance the IPSS, quality of life, and UFM results. However, those with DU and an unobstructed bladder outlet face a comparatively high risk of treatment failure. Preoperative detrusor overactivity and urinary catheterization are associated with more favorable surgical outcomes. Consequently, active deobstructive surgery should be considered for patients with DU who are experiencing urinary retention.

The nucleus tractus solitarii (NTS) is one of the morphologically and functionally defined centers that engage in the autonomic regulation of cardiovascular activity. Phenotypically-characterized NTS neurons have been implicated in the differential regulation of blood pressure (BP). Here, we investigated whether phenylethanolamine N-methyltransferase (PNMT)-expressing NTS (NTS^PNMT) neurons contribute to the control of BP. We demonstrate that photostimulation of NTS^PNMT neurons has variable effects on BP. A depressor response was produced during optogenetic stimulation of NTS^PNMT neurons projecting to the paraventricular nucleus of the hypothalamus, lateral parabrachial nucleus, and caudal ventrolateral medulla. Conversely, photostimulation of NTS^PNMT neurons projecting to the rostral ventrolateral medulla produced a robust pressor response and bradycardia. In addition, genetic ablation of both NTS^PNMT neurons and those projecting to the rostral ventrolateral medulla impaired the arterial baroreflex. Overall, we revealed the neuronal phenotype- and circuit-specific mechanisms underlying the contribution of NTS^PNMT neurons to the regulation of BP.

Aim To explore the material basis of anti-tumor effect of Compound Muji Granules. Methods The anti-tumor pharmacodynamics of Compound Muji Granules in vitro was studied by microfluidic chip technology. The fingerprint of Compound Muji Granules was established by HPLC. The "Spectrum-Material-Effect" of Compound Muji Granules was analyzed by grey correlation analysis,partial least squares regression analysis and network pharmacology approach. Results Seven batches of Compound Muji Granules with different extraction methods were successfully established. The results of grey correlation analysis showed that there was a positive correlation between Compound Muji Granules and 7 of the 14 components with pharmacodynamic correlation coefficient >0.80. The contribution of anti liver tumor was peak number 48(luteolin)>6(gallic acid)>19(chlorogenic acid)>59(quercetin)>67(kaempferol)>65(naringin)>38(ellagic acid),in that order. Conclusions Through the establishment of "Spectrum-Material-Effect" research method,it is clear that the above seven active monomers may be the anti-tumor material basis of Compound Muji Granules.

OBJECTIVE: To analyze the cement flow in the abutment margin-crown platform switching structure by using the three-dimensional finite element analysis, in order to prove that whether the abutment margin-crown platform switching structure can reduce the inflow depth of cement in the implantation adhesive retention. METHODS: By using ANSYS 19.0 software, two models were created, including the one with regular margin and crown (Model one, the traditional group), and the other one with abutment margin-crown platform switching structure (Model two, the platform switching group). Both abutments of the two models were wrapped by gingiva, and the depth of the abutment margins was 1.5 mm submucosal. Two-way fluid structure coupling calculations were produced in two models by using ANSYS 19.0 software. In the two models, the same amount of cement were put between the inner side of the crowns and the abutments. The process of cementing the crown to the abutment was simulated when the crown was 0.6 mm above the abutment. The crown was falling at a constant speed in the whole process spending 0.1 s. Then we observed the cement flow outside the crowns at the time of 0.025 s, 0.05 s, 0.075 s, 0.1 s, and measured the depth of cement over the margins at the time of 0.1 s. RESULTS: At the time of 0 s, 0.025 s, 0.05 s, the cements in the two models were all above the abutment margins. At the time of 0.075 s, in Model one, the gingiva was squeezed by the cement and became deformed, and then a gap was formed between the gingiva and the abutment into which the cement started to flow. In Model two, because of the narrow neck of the crown, the cement flowed out from the gingival as it was pressed by the upward counterforce from the gingival and the abutment margin. At the time of 0.1 s, in Model one, the cement continued to flow deep inside with the gravity force and pressure, and the depth of the cement over the margin was 1 mm. In Model two, the cement continued to flow out from the gingival at the time of 0.075 s, and the depth of the cement over the margin was 0 mm. CONCLUSION When the abutment was wrapped by the gingiva, the inflow depth of cement in the implantation adhesive retention can be reduced in the abutment margin-crown platform switching structure.

This study evaluated the scientific nature and effectiveness of iterative optimization of prevention and control measures for local outbreaks caused by the BA.2 and BA.5.2 COVID-19 strains in Fujian Province in 2022,to provide a scientif-ic basis for responding to future new or recurrent respiratory infectious diseases.According to the theory of infectious disease dynamics,relevant information regarding the local epidemic situation caused by the BA.2 sub-type Omicron virus strain in March 2022 and BA.5.2 sub-type Omicron virus strain in October 2022 in Fujian Province was collected.The susceptible exposed infectious removed(SEIAR)model of COVID-19 infection with a latent period and asymptomatic infected persons was used to analyze the transmission dynam-ics of two local epidemic situations,and evaluate the preven-tion and control effects.The incubation period of the BA.2 epidemic was 3 days(1～9 days),the intergenerational inter-val was 3 days(1～5 days),and the initial Rt was 3.0(95％CI:2.7～3.3).The incubation period of the BA.5.2 epidemic was 2 days(1～6 days),the intergenerational interval was 1 day(0～2 days),and the initial R,was 1.9(95％CI:1.7～2.1).The fittingresults for the BA.2 and BA.5.2 epidemics were good,and no statistical difference was observed between the predic-ted and actual numbers of cases(x2BA.2=31.53,x2BA.5.2=27.88,P＞0.05).If an emergency response had not been initiated,the BA.2 epidemic would have continued to spread andpeak on April 7th,with an estimated 638 035 cases.The BA.5.2 epidemic would have rapidly spread,reaching a peak on November 14th,with an estimated 685 940 cases.If one incubation period were detected early,the scale of the BA.2 epidemic would have decreased by 25.73％;if two incubation periods were detected early,the scale would have decreased by 79.56％,and if one incubation period had been delayed,the scale would have expanded by 13.72％.If one incubation period had been detected early in the BA.5.2 epidemic,the scale would have decreased by 35.04％;if two incubation periods had been detected early,the scale would have decreased by 92.47％;and if one incubation period had been delayed,the scale would have increased by 19.75％.The guiding ideology,and the prevention and control measures for handling two local epidemics were optimized and iterated.Our study indicated that implementing the"four early"measures ef-fectively decreased the scale of the epidemic,and earlier detection was associated with more significant control effects.This study provides valuable information for the prevention and control of new or recurrent respiratory infectious diseases.

Objective: To report the clinical features and genetic variations of monogenic lupus caused by DNASE1L3 deficiency and to introduce preliminary experience on diagnosis and treatment for this disease. Methods: Clinical data of 3 children from the same pedigree were collected who were diagnosed with DNASE1L3 defect-associated monogenic lupus in August 2020 by Department of Pediatrics, Peking Union Medical College Hospital referred from Department of Pediatrics, Boai Hospital of Zhongshan. DNA was extracted from the peripheral blood of the patients and their parients to perform genetic analysis and confirmation. Six interferon-stimulated genes were relatively quantified to examine the activation of the type I interferon signaling. "DNASE1L3" "systemic lupus erythematosus" and "SLE" were searched in PubMed, Wangfang Data, CNKI databases for related reports from database established date to June 2022. Spectrum of genetic variations and clinical phenotypes were analyzed in combination with this pedigree. Results: Case 1, a 14-year-old girl with edema, hematuria, and heavy proteinuria, presented with membranous nephropathy. Case 2, the 12-year-old younger brother of case 1 with hematologic, cardiac, pulmonary, renal involvement, positive antinuclear antibody, positive anti-double-stranded DNA antibody and low complement C3, manifested with systemic lupus erythematosus. Case 3, the 8-year-old younger sister of case 1 with hematologic, cardiac, pulmonary and renal involvement, positive antinuclear antibody, positive anti-double-stranded DNA antibody, and low complement C3 and C4, manifested with systemic lupus erythematosus. Genetic testing revealed that all 3 patients carried homozygous deletions in exons 3 and 4 on DNASE1L3 gene. Interferon scores were elevated in case 1, 2 and their parents but normal in case 3. All 3 patients were diagnosed with monogenic lupus caused by DNASE1L3 defects. Literature searching identified 10 relevant publications in English and 0 publication in Chinese, involving 42 patients from 18 pedigrees (including the 3 cases from this pedigree). Nine variants were found: c.289_290delAC (p.T97Ifs*2), c.643delT (p.W215Gfs*2), c.320+4delAGTA, c.321-1G>A, Ex5 del, c.433G>A, c.581G>A (p.C194Y), c.537G>A (p.W179X), and Ex3-4 del. The hotspot variants were c.643delT (43% (36/84)) and c.289_290delAC (36% (30/84)). Kidney was affected in 31 cases (74%) of the 42 cases. Among the 25 patients, joints were affected in 16 cases (64%), fever were reported in 13 cases (52%) hematologic system was involved 13 cases (52%), rash was present in 10 cases (40%), intestinal tract was involved in 8 cases (32%), lungs were involved in 6 cases (24%), eyes were involved in 4 cases (16%), and the heart was involved in 4 cases (16%). The 2 cardiopulmonary affected patients from literature showed poor prognosis, with 1 died, and 1 right heart failure. Conclusions: The clinical manifestations of monogenic lupus caused by DNASE1L3 defect are highly heterogenous, primarily with renal, blood, joint, intestinal, and cardiopulmonary involvement. There is no correlation between the genotype and the phenotype. DNASE1L3 defects were predominantly mediated by null varations including nonsense, splicing, frameshift and exon deletions. The hotspot variants are c.643delT and c.289_290delAC. DNASE1L3 defects should be cautioned in early-onset lupus-like patients with renal, joint and hematologic involvement. Cardiopulmonary involved patients require close monitoring for poor prognosis. Copy number variations should be carefully analyzed after negative whole exome sequencing.

The clinical randomized controlled trial(RCT) of Chinese patent medicine in the treatment of influenza were reviewed and analyzed to provide basic information for clinical decision and related research. On the basis of the collection in the Traditional Chinese Medicine(TCM) Clinical Evidence Database System(EVDS), CNKI, Wanfang, VIP, SinoMed, EMbase, PubMed, and Cochrane Library were searched for RCTs of Chinese patent medicine for influenza published from database inception to July 25, 2021. The publication time, sample size, intervention and control measures, course of treatment, outcome indicators, and methodological quality of the trials were analyzed and evaluated. Ninety-two RCTs of Chinese patent medicine for influenza published between 2005 and 2021, were included, among which 17 RCTs(18.48%) had a sample size higher than 200 and the average sample size was about 145. Twenty-seven Chinese patent medicines were involved, including twenty-one oral medicines and six injections. The Chinese patent medicines in trials reported in more than five papers included Lianhua Qingwen Capsules/Gra-nules, Tanreqing Injection, and Reduning Injection. Fourteen intervention protocols were reported, of which Chinese patent medicine+western medicine+conventional treatment vs western medicine+conventional treatment(20.65%) was the most frequently employed. Additionally, 85.87% of the RCTs reported the course of treatment, and 80.43% of the RCTs determined 3-7 d as the intervention course. Forty-five outcome indicators were extracted, which were used 434 times, including symptoms/signs, physicochemical detection, safety events, TCM symptoms/syndromes, quality of life, long-term prognosis, and economic evaluation. Symptoms/signs(61.52%) exhibited the highest frequency. Methodological problems were prevalent in the included trials. The findings reveal that there are few clinical trials on influenza treatment by Chinese patent medicine, and the methodological problems are prominent, affec-ting the reliability and practicability of the trials. In the future research, the value characteristics of Chinese patent medicine should be highlighted and the quality control in the whole process should be strengthened based on the scientific and rigorous design.

Objective:To systematically review the teaching effect of problem-based learning (PBL) combined with evidence-based medicine (EBM) teaching mode on the standardized residency training.Methods:CNKI, Wanfang database, VIP database, SinoMed, Embase, PubMed and Web of SCI databases were searched, and the randomized controlled trial (RCT) studies of the application of EBM combined with PBL teaching in standardized residency training were collected. The retrieval time was from the establishment to 1st July, 2018. Two investigators independently extracted data and assessed the quality of the studies. After assessing the risk of bias of included studies, Meta-analysis was performed on RevMan 5.3.Results:In total, 4 studies were included in the review. Narrative assessment was adopted, because outcome indicators of these study were varied and the quality of the literatures could not meet the requirement of Meta-analysis. Our study suggested that the residents who were in PBL combined with EBM teaching mode group got higher scores in the standardized residency training, compared with those in the lecture-based learning (LBL) teaching mode group, especially in case analysis score, total score of examination, improvement of clinical thinking ability, communication and expression ability, organization and cooperation ability, etc.Conclusion:The current evidence suggests that the application of EBM combined with PBL teaching mode has a positive effect on the standardized residency training. Compared with the traditional LBL teaching, EBM can improve students' ability. However, limited by the quantity and quality of included studies, the above conclusions still need to be verified by more studies with larger samples and higher quality.
