Based on the modern understanding that lipid metabolism disorders mediate tumor microenvironmental imbalance in esophageal carcinoma， this paper proposes that failure of spleen and kidney warming and internal accumulation of phlegm-toxin constitute the core pathogenesis of esophageal carcinoma. Deficiency of spleen and kidney yang qi serves as the root cause， while impaired transformation and transportation of lipids and the accumulation of phlegm-toxin represent the superficial manifestations. Phlegm originates from the transformation of lipids， while toxin arises from and attaches to phlegm. Their interaction forms a sticky and persistent pathological state that runs throughout the entire disease process. The evolution of pathogenesis follows a dynamic and progressive pattern. In the early stage， failure of spleen and kidney warming and dysfunction of lipid metabolism mediate abnormalities in a lipid-enriched microenvironment； in the middle stage， lipid turbidity condenses into phlegm， and phlegm-toxin stasis promotes the formation of an inflammatory and hypercoagulable microenvironment； in the late stage， dysfunction of the sanjiao （三焦） warming function and impaired qi transformation lead to an imbalance in the hypoxic and metabolically dysfunctional microenvironment. Accordingly， a staged therapeutic approach is proposed， including warming the kidney and strengthening the spleen， transforming phlegm and resolving toxin， and warming and unblocking the sanjiao. By regulating lipid metabolism to restore tumor microenvironmental homeostasis， this approach provides a new theore-tical perspective and practical strategy for the intervention of esophageal cancer progression through traditional Chinese medicine.

Radiation enteritis(RE)is an inflammatory reaction caused by radiation exposure,commonly observed following radiotherapy for malignancies in the abdominal,pelvic and retroperitoneal regions.The authors believe that the pathogenesis of RE is complex,involving factors such as deficiency and excess,cold and heat,as well as qi and blood.The general pathogenesis can be summarized as"instability of the Zhongzhou,depletion of essence and blood,dysregulation of ascending and descending,and accumulation of heat-toxins".And"the instability of the Zhongzhou and subsequent malnutrition of the intestines"are the key drivers of disease progression.Based on theoretical exploration and clinical observations,this article proposed a comprehensive diagnostic and therapeutic approach centered on"stabilizing the Zhongzhou,replenishing essence and blood,regulating ascending and descending functions,and clearing heat-toxins".These four methods are often applied simultaneously,with"stabilizing the Zhongzhou and regulating the intestines"serving as the core of treatment.The approach is tailored according to the individual patient's condition of blood,qi and body fluids.A medical case was attached as evidence for verification.

ObjectiveTo investigate the incidence of stroke in patients with type 2 diabetes mellitus (T2DM) in the community of Shanghai, and to explore its influencing factors. MethodsA two-way cohort study was used to observe the incidence of stroke in a dynamic cohort of14 743 community-based T2DM patients who were enrolled for management from January 2016 to December 2018 in Hongkou District, Shanghai. All the research subjects were followed up for 3 years to observe the stroke occurrence. Outcome events were retrospectively collected from the Shanghai Stroke and Acute Myocardial Infarction Registry Reporting Information System and the Cause of Death Registry System, and information on stroke onset and verification of past medical history were collected by family physicians through clinic follow-up, home follow-up, and telephone follow-up. Cox proportional hazards model was used to identify the risk factors of stroke in TDM2 patients, and the hazard ratio (HR) and its 95% confidence interval (CI) were calculated. ResultsAfter a mean follow up of 3.5 years, the standardized incidence of stroke in patients with T2DM was 8.65‰, and the risk of standardized incidence was 3.50 (95%CI: 3.26‒3.77) compared with that of the total national population. Cox proportional hazards regression analysis showed that age (HR=1.18, 95%CI: 1.13‒1.23), being female (HR=1.14, 95%CI: 1.01‒1.29), physical activity <600 metabolic equivalent (MET)·min·week^-1 (HR=1.24, 95%CI: 1.06‒1.44), substandard of HbA1c control (HR=1.16, 95%CI: 1.03‒1.30), occasional smoker(HR=1.23, 95%CI: 1.04‒1.45), and those who took insulin therapy (HR=1.36, 95%CI: 1.11‒1.66) were associated with an increased risk of stroke, while those received contracted services from family doctors were associated with a decreased risk of stroke(HR=0.78, 95%CI: 0.71‒0.88). ConclusionCommunity T2DM population in Shanghai has a high risk of stroke. It is necessary to continue to explore the positive role of family doctor contract service management model, strengthen individualized exercise, smoking cessation and other lifestyle interventions, and strictly control blood glucose as soon as one can to delay or avoid the occurrence of complications.

Objective To explore the mechanism by which She-Ti-Zhi-Qiu decoction alleviates allergic rhinitis (AR) through gut microbiota-mediated regulation of T helper cell 17(Th17)/regulatory T cells(Treg) balance and related cytokines. Methods Twenty-eight female SD rats were randomly divided into four groups: the Control group, Model group, STZQ group, and Probiotics group. Except for the Control group, all other groups were sensitized with ovalbumin (OVA) to establish AR models. The Control and Model groups received intragastric administration of normal saline, while the STZQ group was administered She-Ti-Zhi-Qiu Decoction, and Probiotics group received probiotics. After two weeks of continuous intragastric administration, nasal mucosa, serum, peripheral blood, and colon contents were collected. The inflammation of nasal mucosal tissue was assessed via HE staining. 16S rDNA sequencing was used to detect and analyze the structure and content of bacteria in colon contents. Flow cytometry was used to detect the relative proportions of Treg and Th17 cells in peripheral blood. ELISA was used to measure the levels of Th17- and Treg-related cytokines in serum. Results Compared with the Control group, the Model group showed an inflammatory response in nasal mucosal tissue, along with increased IL-17A and IL-17E levels and decreased IL-10 levels. The percentage of Th17 cells in peripheral blood increased, while the percentage of Treg cells decreased. Beneficial bacteria in the intestine were decreased, while pathogenic bacteria were increased. Compared with the Model group, the STZQ group showed lower serum IL-17A and IL-17E levels and higher IL-10 levels. The percentage of Th17 in peripheral blood decreased, while the percentage of Treg increased. There was an increase in beneficial bacteria in the intestine and a decrease in pathogenic bacteria. The changes in the microbiota were correlated with IL-17A, IL-17E, and IL-10 levels. Conclusion She-Ti-Zhi-Qiu decoction can ameliorate the inflammation of AR by regulating gut microbiota and Th17/Treg immune balance.

PURPOSE: Hidden blood loss (HBL) during the perioperative period significantly impacts postoperative recovery and complications, yet it is frequently disregarded. This study aimed to investigate the effects of tip-apex distance (TAD) and calcar-referenced tip-apex distance (calTAD) on HBL in the treatment of intertrochanteric fractures utilizing proximal femoral nail antirotation (PFNA). The study also seeks to evaluate the possible decrease in HBL subsequent to PFNA treatment by optimizing nail positioning. METHOD: A historical cohort study was conducted from January 2020 to December 2022. Patients diagnosed with unilateral acute closed femoral intertrochanteric fracture and who underwent PFNA internal fixation surgery met the inclusion criteria, and were grouped according to the value of calTAD and TAD. The participants were divided into low TAD group (TAD<20 mm) and high TAD group (TAD≥20 mm); low calTAD group (calTAD<7.625 mm) and high calTAD group (calTAD≥7.625 mm), respectively. The primary outcome measures were intraoperative blood loss (including HBL, overt blood loss, and total blood loss). Continuous data were analyzed using an independent sample t-test or Mann-Whitney U test, and categorical data were analyzed using the Pearson Chi-square test. Univariate analysis was used to evaluate the association between various indicators and perioperative HBL. A stepwise multiple linear regression analysis model was used to determine the independent factors affecting perioperative HBL. A p value less than 0.05 was considered statistically significant. RESULTS: A total of 131 patients were initially included, of which 80 were assigned to the calTAD group (with 61 in the high calTAD group and 19 in the low calTAD group), and 80 were assigned to the TAD group (with 34 in the high TAD group and 46 in the low TAD group). The average HBL for the low TAD group was 772.85 mL, whereas for the high TAD group it was 919.68 mL (p>0.05). The average HBL for the low calTAD group was 611.42 mL, whereas for the high calTAD group it was 904.97 mL (p<0.05). Subsequent analysis revealed that the patient's height, preoperative hemoglobin levels, changes in hemoglobin and hematocrit levels from pre- to post-surgery, and calTAD are independent risk factors influencing HBL. CONCLUSION In summary, our investigation revealed a significant correlation between the positioning of nails in PFNA and HBL during the perioperative period. By optimizing the placement of the cephalic nail, specifically by ensuring a calTAD of less than 7.625 mm, a significant decrease in HBL can be attained. Additionally, we identified that height, preoperative hemoglobin, differences in preoperative and postoperative hemoglobin and hematocrit, and the positioning of the cephalic nail were independent risk factors for HBL.

Cholesterol (CH) plays a crucial role in enhancing the membrane stability of drug delivery systems (DDS). However, its association with conditions such as hyperlipidemia often leads to criticism, overshadowing its influence on the biological effects of formulations. In this study, we reevaluated the delivery effect of CH using widely applied lipid microspheres (LM) as a model DDS. We conducted comprehensive investigations into the impact of CH on the distribution, cell uptake, and protein corona (PC) of LM at sites of cardiovascular inflammatory injury. The results demonstrated that moderate CH promoted the accumulation of LM at inflamed cardiac and vascular sites without exacerbating damage while partially mitigating pathological damage. Then, the slow cellular uptake rate observed for CH@LM contributed to a prolonged duration of drug efficacy. Network pharmacology and molecular docking analyses revealed that CH depended on LM and exerted its biological effects by modulating peroxisome proliferator-activated receptor gamma (PPAR-γ) expression in vascular endothelial cells and estrogen receptor alpha (ERα) protein levels in myocardial cells, thereby enhancing LM uptake at cardiovascular inflammation sites. Proteomics analysis unveiled a serum adsorption pattern for CH@LM under inflammatory conditions showing significant adsorption with CH metabolism-related apolipoprotein family members such as apolipoprotein A-V (Apoa5); this may be a major contributing factor to their prolonged circulation in vivo and explains why CH enhances the distribution of LM at cardiovascular inflammatory injury sites. It should be noted that changes in cell types and physiological environments can also influence the biological behavior of formulations. The findings enhance the conceptualization of CH and LM delivery, providing novel strategies for investigating prescription factors' bioactivity.

Transalveolar technique for sinus floor elevation(TSFE)offers the advantages of minimal invasiveness,reduced postoperative reaction,and shorter operative time for vertical bone augmentation in the maxillary posterior region.The clinical data of one patient with severe deficiency of residual bone height(RBH)in the maxillary posterior region,a blood vessel visible in the lateral wall of the maxillary sinus and a visible septum at the floor of the maxillary sinus were reported,and two-stage flexible TSFE was used to improve the vertical bone height of the operated area while reducing trauma,the risk of Schneiderian membrane rupture and maxillary sinus infection,etc.,and the relevant literatures were reviewed.The patient,male,26 years old,complained of missing left maxillary posterior teeth for more than 1 year and requested restoration.The patient had 27 missing teeth,normal keratinized gingiva,full alveolar ridge,no elongation of the opposing teeth,fair width of the proximal and normal occlusal distance.The results of cone beam CT(CBCT)showed that the distance between the sinus crests at the site of the 27 teeth was about 3 mm,the width of the alveolar bone was about 12.8 mm,the bone density was normal,and there were no residual roots or other abnormalities;no cyst-like lesions were seen in the walls of the maxillary sinuses bilaterally,and separation was seen at the floor of the maxillary sinus on the left side and a blood vessel was seen in the lateral wall of the maxillary sinus.A diagnosis of Kennedy class Ⅱ maxillary tooth defects was made.After two stages of TSFE,the Schneiderian membrane was intact and the bone height of the implant area was elevated to 9.6 mm from 3 mm preoperatively after the completion of the restoration,with stable bone augmentation,good osseointegration,and restoration of normal occlusal function.For the patients with severe bone height deficiency in the maxillary posterior region,flexible two-stage TSFE should be considered,which can help to reduce the risk of maxillary sinus infection and Schneiderian membrane rupture while minimizing the damage and obtaining the ideal bone augmentation results.
