Asthma is a chronic inflammatory respiratory disease involving multiple cells and cellular components， characterized by recurrent episodes of wheezing， shortness of breath， chest tightness， and coughing， significantly impacting patients' quality of life. The phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt） signaling pathway， as a crucial hub in intracellular signaling， is widely involved in the regulation of cell growth， proliferation， survival， metabolism， and a series of pathophysiological processes. Its regulatory role in the pathological progression of asthma is particularly significant， specifically in promoting airway inflammation， mediating epithelial mesenchymal transition， accelerating airway remodeling， regulating cell autophagy， inducing mucus hypersecretion， and influencing immune response balance. This study analyzed potential molecular targets of the PI3K/Akt pathway， including activators such as cysteine proteinase inhibitor 1（CST1）， found in inflammatory zone 1（FIZZ1） and free fatty acid receptor 1（FFAR1）， and inhibitors such as human β-defensin-3（hBD-3）， disintegrins， metalloproteinase 33（ADAM33） and interleukin-27（IL-27）， and initially revealed the potential molecular mechanisms of traditional Chinese medicine（TCM） in asthma intervention. Based on this， the authors systematically summarized the efficacy and specific mechanisms of TCM monomers， compounds， and external treatments for asthma by regulating the PI3K/Akt signaling pathway through literature review and analysis， aiming at establishing a robust foundation for the wide application and advanced development of TCM in asthma treatment， offering innovative insights for clinical research and drug development of asthma.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Breast augmentation using polyacrylamide hydrogel (PAHG) was widely used in China. We present the first case of delayed breast inflammation after 2019 novel coronavirus(2019-nCoV) infection in a patient who recieved breast augmentation with PAHG 20 years ago, without any other predispositions. The 45-year-old female patient complained of severe breast swelling and pain three weeks after 2019-nCoV infection. The swelling extended from the upper clavicle to the upper abdomen. Delayed inflammation reaction was diagnosed, followed by emergency surgery. During the surgery, the injected material was observed to gush out in a form of greenish and thin paste, with a foul odor. The wound had extensive diffuse oozing and hemoglobin decreased significantly. The patient was discharged one week after surgery. During a three-month follow-up, she experienced weakness and fatigue with no complications. There are still many unknown areas of the impact of 2019-nCoV on human foreign bodies and immune system, which is diverse and complex. Reporting various possible symptoms and mechanisms is conducive to improving the level of awareness and intervention of plastic surgeons.

ObjectiveTo observe the effects and underlying mechanisms of Fagopyri Dibotryis Rhizoma extract on the proliferation， apoptosis， and autophagy of human colorectal cancer HCT-116 cells. MethodFirstly， cellular activity was detected by the cell proliferation and activity-8 （CCK-8） assay， and the half inhibition rate （IC₅₀） was calculated. Blank group and Fagopyri Dibotryis Rhizoma group （2， 4， 8 mg·L^-1） were set. The effect of Fagopyri Dibotryis Rhizoma on the proliferation of HCT-116 cells was observed by cloning experiments， and that of Fagopyri Dibotryis Rhizoma on apoptosis was observed by flow cytometry. The expressions of autophagy-related proteins， p38 mitogen-activated protein kinase （p38 MAPK）， extracellular signal-regulated kinase （ERK）， c-Jun amino-terminal kinase （JNK）， phosphorylated （p）-p38， p-ERK， p-JNK， and other proteins were detected by Western blot. Finally， flow cytometry instrumentation and fluorescence microscopy were used to analyze the changes in reactive oxygen species （ROS）， and a ROS scavenger （NAC） was adopted for verification. ResultCompared with the blank group， the activity of HCT-116 cells was significantly decreased in the Fagopyri Dibotryis Rhizoma group （P<0.05， P<0.01）. The apoptosis rate of HCT-116 cells in the Fagopyri Dibotryis Rhizoma group was significantly increased （P<0.01）. The expression of autophagy-related protein ubiquitin-binding protein （p62） was decreased， but that of autophagy-specific genes （Beclin1） and autophagic microtubule-associated protein 1 light-chain 3B （LC3B） was enhanced （P<0.05， P<0.01）. Compared with the Fagopyri Dibotryis Rhizoma group， the apoptosis rate of HCT-116 cells in the Fagopyri Dibotryis Rhizoma + NAC group was significantly reduced （P<0.01）. The expression of related autophagy protein Beclin1 was significantly reduced （P<0.01）， and that of LC3B protein was reduced （P<0.01）. In addition， the expression of MAPK pathway-related proteins ERK and JNK was decreased in the Fagopyri Dibotryis Rhizoma group （P<0.05， P<0.01）， and that of p-ERK and p-JNK was enhanced （P<0.05， P<0.01）. ConclusionFagopyri Dibotryis Rhizoma can inhibit the proliferation of HCT-116 cells and induce apoptosis and autophagy through the ROS/MAPK signaling pathway.

Objective:To explore the safety and efficacy of prophylactic superdrainage using superficial inferior epigastric vein (SIEV) in delayed single-pedicled deep inferior epigastric perforator (DIEP) flap breast reconstruction.Methods:The clinical data of all patients who underwent single-pedicle DIEP flap delayed breast reconstruction in Department of Comprehensive Breast Plasty Surgery, Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from May 2018 to August 2022 were retrospectively analyzed. According to whether SIEV-internal thoracic vein anastomosis was performed, they were divided into superdrainaged group and non-superdrainaged group. The diameter of SIEV and the time required for anastomosis were recorded. The total operation time, flap ischemia time, hospital stay, the rates of flap diffuse congestion, overall complications and second operation were compared between the two groups. The relative risks of flap diffuse congestion, complications and second operation were calculated. SPSS 24.0 software was used for data analysis. Measurement data was expressed as Mean±SD, independent sample t test was used for analysis. Counting data was expressed as %, and χ2 test was used for analysis. P<0.05 was considered statistically significant. Results:A total of 45 patients were included, including 26 patients in the non-superdrainaged group and 19 patients in the superdrainaged group. The total operation time was (7.7±1.9) h and (8.4±1.5) h, the flap ischemia time was (89.5±10.4) min and (92.6±12.3) min, and the hospital stay was (6.6±1.8) d and (6.6±2.0) d, respectively. There were no significant differences ( P>0.05). In the superdrainaged group, the diameter of SIEV was (2.5±0.3) mm, and manual suture was used. The time required for anastomosis of one SIEV was (12.2±2.3) min. The rates of diffuse congestion, recipient site complications, donor site complications and second operation were 7.7%(2/26), 15.4%(4/26), 7.7%(2/26) and 15.4%(4/26) in the non-superdrainaged group, and 0(0/19), 5.3%(1/19), 10.5%(2/19) and 5.3%(1/19) in the superdrainaged group, respectively. There were no significant differences between the two groups ( P>0.05). The relative risks were 3.7, 2.9, 0.7 and 2.9, respectively. Conclusion:Prophylactic superdrainage using SIEV is safe and effective. It can minimize the potential rate of diffuse venous congestion and secondary surgery, and not at the expense of increased flap ischemia time and abdominal complications in the meanwhile.

In deep inferior epigastric perforator (DIEP) flap breast reconstruction, diffuse venous congestion caused by non-pedicle causes, such as lack of effective communication between deep and superficial venous systems, is very rare. In this paper, a case of young woman who underwent DIEP breast reconstruction after breast cancer mastectomy was reported. Imaging findings showed the absence of bilateral dominant perforators and the lack of communication between the deep and superficial venous system. During operation, the superficial inferior epigastric vessels were dissected in advance. Indocyanine green angiography showed arterial perfusion insufficiency and venous congestion.The flap was successfully salvaged by supercharging/draining with superficial inferior epigastric vessels, preserving the abdominal function of the young patient to the greatest extent.
