Secondary organizing pneumonia after infection is a pathological condition characterized by connective tissue filling and obstructing the alveoli and bronchioles, in which following an infection in the lung, the inflammatory response is not controlled in a timely and effective manner. The pathogenesis and treatment of this condition can be interpreted through the Sanjiao membranous tube theory and the concept of stagnation within the pulmonary micro-membrane. Sanjiao is conceptualized as a four-way membranous tube that internally connects with the zangfu organs and externally with the skin and muscles, enabling the circulation of energy and fluids throughout the body. It also maintains communication with the zangfu micro-membranes. Within the lungs, the pulmonary micro-membrane is distributed and connected to the upper jiao membranous tube, facilitating the movement of qi and fluids and supporting nutrient distribution. External pathogens may invade the Sanjiao membranous system through the external membranous tube, travel internally along this system, and transform into latent pathogens that settle within the pulmonary micro-membrane. These latent pathogens can subsequently transform into heat or dampness, leading to the depletion of lung qi and impairing the lung′s ability to regulate and transport body fluids. Consequently, fluids may seep into the pulmonary micro-membrane, where they are transformed into dampness, turbidity, and phlegm. The accumulation of damp-turbidity and phlegm obstructs the flow of qi and blood, resulting in blood stasis in the pulmonary collaterals. This stagnation occurring within both the pulmonary micro-membrane and its associated collaterals underlies the development of secondary organizing pneumonia after infection. In severe cases, this condition may progress to pulmonary interstitial fibrosis. The therapeutic approach emphasizes expelling latent pathogens, regulating and dredging the pulmonary micro-membrane, tonifying the healthy qi, and supporting health. Regulating and dredging the pulmonary micro-membrane is a crucial step, with a focus on promoting the flow of lung qi, resolving dampness and phlegm, and activating blood circulation to remove stasis.

Background and Aims:Implant-based breast reconstruction is one of the most common reconstructive approaches after mastectomy for breast cancer.However,the incidence of postoperative complications remains significant,and the associated risk factors have not been fully elucidated.This study aimed to analyze the incidence of surgical complications following implant-based breast reconstruction in patients undergoing mastectomy at our center and to identify potential risk factors.Methods:A retrospective analysis was conducted on patients who underwent mastectomy and implant-based breast reconstruction at Sun Yat-sen Memorial Hospital between May 2004 and August 2022.Patients were grouped according to the presence or absence of postoperative surgical complications,and multivariate Logistic regression was used to identify independent risk factors.Results:A total of 545 patients with 602 reconstructed breasts were included.Surgical complications occurred in 13.6%(82/602)of the cases,including infection,wound dehiscence/poor healing,flap or nipple-areola necrosis,and implant leakage/rupture.Multivariate analysis revealed that nipple-areola complex resection(OR=1.934,95%CI=1.056-3.542,P=0.033),postoperative radiotherapy(OR=2.483,95%CI=1.527-4.036,P<0.001),implant volume≥300 mL(OR=1.663,95%CI=1.025-2.696,P=0.039),and surgeon experience with fewer than 10 cases(OR=1.804,95%CI=1.092-2.979,P=0.021)were all independent risk factors for complications.Conclusion:NAC resection,radiotherapy,large implant volume,and limited surgical experience are important independent risk factors for postoperative surgical complications following implant-based breast reconstruction.Thorough preoperative evaluation and appropriate surgical planning are essential to minimize risks.

Objective To explore the role of pseudogene AC106872.1 in maintaining the self-renewal capacity of human embryonic stem cells(hESCs).Methods AC106872.1 was knocked out in hESCs and knockout effi-ciency was validated by PCR and agarose gel electrophoresis.The colony formation of hESCs was assessed through colony formation assays and alkaline phosphatase(AP)staining.The expression level of pluripotency and differ-entiation marker genes was analyzed by qPCR and flow cytometry.RNA sequencing(RNA-seq)was performed to assess transcriptomic changes upon AC106872.1 knockout.Results Knockout of AC106872.1 significantly in-hibited the colony formation of hESCs(P＜0.05).The expression level of pluripotency marker genes was signifi-cantly reduced(P＜0.000 1),while the expression of differentiation marker genes was markedly increased(P＜0.000 1).Conclusions The pseudogene AC 1 06872.1 plays a crucial role in maintaining human embryonic stem cell self-renewal through regulation of pluripotency genes expression.

Systemic sclerosis is an autoimmune rheumatic disease that often leads to multisystem diseases,frequently resulting in pulmonary interstitial fibrosis.According to the theory of sanjiao(triple energizers)membranous channels,sanjiao connects the five zang-organs and six fu-viscera internally and the skin,muscles,and bones externally.It serves as a four-way membranous channel that connects internal organs and external structures,linking with the micromembranes of organs and blood vessels.The pathogenesis of pulmonary interstitial fibrosis secondary to systemic sclerosis involves external cold obstructing the skin and interstitial layers,impairing the defense qi and defense yang,which originate in the essence of the kidney.This leads to weak defensive qi and kidney deficiency,causing stagnation in sanjiao's energy flow and disruption of water and gasification and loss of fluid,resulting in accumulation of dampness,phlegm,and blood stasis.These obstructive factors spread along sanjiao's membranous channels,leading to multiorgan micromembrane involvement and systemic damage.The lungs,which are in direct contact with the external environment,are particularly susceptible to invasion by external pathogens.When combined with stagnation of dampness,phlegm,and blood in the lungs,this leads to secondary pulmonary fibrosis,resulting in lung dysfunction.Continuous stagnation of sanjiao exacerbates the overall condition of the patient,leading to a mixed cold-heat imbalance.Treatment focuses on"unblocking,transforming,and regulating"to restore sanjiao function,promote qi and fluid circulation,invigorate blood,and adjust the cold-heat imbalance,ultimately restoring the overall condition of the patient.

Objective:To explore the optimization of the standardized assessment tool for clinical diagnosis of Chinese developmental dyslexia (DD).Methods:A cross-sectional study was conducted from May to December 2023, in which 130 primary school children in grades 1 to 3 with clinical signs of literacy lag and positive screening results on the screening scales were recruited from the outpatient clinic of Child Health Care Medical Division, Shanghai Children′s Hospital, Shanghai Jiao Tong University School of Medicine. Chinese dyslexia screening behavior checklist for primary students (CDSBC) was used as the screening scales, and supplemented by dyslexia checklist for Chinese children. Referring to the standard procedure of the"expert advice on diagnosis and intervention of Chinese developmental dyslexia", the developmental dyslexia scale for standard mandarin (DDSSM) was used to evaluate the children′s literacy-related cognitive abilities and conduct the diagnostic assessment, and divided the children into learning backward group and the DD group. The t-test and χ2 test were used to compare the differences in the distribution of intelligence, literacy and attention deficit hyperactivity disorder between the two groups. Spearman′s correlation was used to analyze the correlation between the scores for each cognitive ability in the DDSSM and the CDSBC. Results:Of the 130 children, 90 were male, aged (8.3±1.0) years; 40 were female, aged (8.1±0.9) years. A final diagnosis of DD was made in 59 cases, of which 41 were males. There was no statistically significant difference in operational intelligence quotient (101±15 vs.100±15, t=0.53, P>0.05) and statistically significant difference in literacy of DDSSM (32±5 vs.21±4, t=11.56, P<0.001) between the learning backward group and the DD group. Eighteen cases (25.4%) of the learning backward group were children with attention deficit subtype attention deficit hyperactivity disorder (ADHD-I), and 16 cases (27.1%) in DD group, the difference in incidence between the two groups was not statistically significant ( χ2=0.05, P>0.05). There were correlations between the DDSSM (for oral vocabulary, morphological awareness and orthographic awareness) and the CDSBC total score ( r=-0.42, -0.32, -0.35, all P<0.01), but the correlations for visuospatial perception and rapid automatized naming with CDSBC total score were not statistically significant ( r=-0.09 and -0.20,both P>0.05). Conclusion:For literacy-related cognitive abilities, screening scales CDSBC are not sufficiently useful for assessment, so the introduction of standardized assessment tools DDSSM is an optimization of the clinical diagnosis of Chinese DD, which is crucial for achieving accurate diagnosis and intervention.

Objective To explore the association between interpregnancy weight change and the recurrence of gestational diabetes mellitus(GDM).Methods This study included women who had two delivery records and a history of GDM during their previous pregnancy at the Guangdong Women and Children Hospital between January 2017 and July 2022.Interpregnancy weight change was defined as the difference between the prepregnancy BMIs of two consecutive pregnancies.Interpregnancy weight change was categorized into four groups(＜-1,-1 to＜1,1 to＜3,≥3 kg/m2),with the-1 to＜1 kg/m2 group serving as the reference.Logistic regression analyses were used to assess the associations of interpregnancy weight changes with GDM recurrence and changes in glucose values during two consecutive pregnancies.Results Among 703 participants,326 individuals(46.4％)experienced GDM recurrence.Compared with the groups with an interpregnancy BMI change of-1 to＜1 kg/m2,the groups with a BMI change of 1 to＜3 or ≥3 presented an increased risk of GDM recurrence,with odds ratio(OR)[95％confi-dence intervals(CI)]of 2.16(1.52-3.08)and 2.56(1.44-4.56),respectively.The risk of GDM recurrence significantly in-creased with increasing interpregnancy weight gain(P for trend＜0.01).However,there was no significant association between a BMI change＜-1 kg/m2 and GDM recurrence,with an OR(95％CI)of 0.95(0.57-1.57).An increase of 1 kg/m2 in the in-terpregnancy BMI was associated with a higher risk of elevated fasting blood glucose and 1 h plasma glucose,with OR(95％C1)of 1.15(1.05-1.26)and 1.21(1.10-1.33),respectively.Conclusion Women with a history of GDM are at a high risk of GDM recurrence,and interpregnancy weight gain is associated with an increased risk of GDM recurrence.These findings under-score the importance of health education among women with a history of GDM who plan to conceive again and emphasize the im-portance of weight management in reducing the recurrence of GDM.
