Objective: To investigate the objective characteristics of tongue manifestation in different stages of damp-heat syndrome in diabetic kidney disease (DKD). Methods: A cross-sectional study enrolled 134 patients with DKD G3-5 stages who met the diagnostic criteria for damp-heat syndrome in DKD. The patients were treated at Dongzhimen Hospital, Beijing University of Chinese Medicine, from May 2023 to January 2024. The patients were divided into three groups: DKD G3, DKD G4, and DKD G5 stage, with 53, 33, and 48 patients in each group, respectively. Clinical general data (gender, age, and body mass index) and damp-heat syndrome scores were collected from the patients. The YZAI-02 traditional Chinese medicine (TCM) AI Tongue Image Acquisition Device was used to capture tongue images from these patients. The accompanying AI Open Platform for TCM Tongue Diagnosis of the device was used to analyze and extract tongue manifestation features, including objective data on tongue color, tongue quality, coating color, and coating texture. Clinical data and objective tongue manifestation characteristics were compared among patients with DKD G3-5 based on their DKD damp-heat syndrome status. Results: No statistically significant difference in gender or body mass index was observed among the three patient groups. The DKD G3 stage group had the highest age (P<0.05). The DKD G3 stage group had a lower score for symptoms of poor appetite and anorexia(P<0.05) than the DKD G5 group. No statistically significant difference was observed in damp-heat syndrome scores among the three groups. Compared with the DKD G5 stage group, the DKD G3 stage group showed a decreased proportion of pale color at the tip and edges of the tongue (P<0.05). The DKD G4 stage group exhibited an increased proportion of crimson at the root of the tongue, a decreased proportion of thick white tongue coating at the root, a decreased proportion of pale color at the tip and edges of the tongue, an increased hue value (indicating color tone) of the tongue color in the middle, an increased brightness value (indicating color lightness) of the tongue coating color in the middle, and an increased thickness of the tongue coating (P<0.05). No statistically significant difference was observed in other tongue color proportions, color chroma values, body characteristics, coating color proportions, coating color chroma values, and coating texture characteristics among the three groups. Conclusion Tongue features differ in different stages of DKD damp-heat syndrome in multiple dimensions, enabling the inference that during the DKD G5 stage, the degree of qi and blood deficiency in the kidneys, heart, lungs, liver, gallbladder, spleen, and stomach is prominent. Dampness is more likely to accumulate in the lower jiao, particularly in the kidneys, whereas heat evil in the spleen and stomach is the most severe. These insights provide novel ideas for the clinical treatment of DKD.

BACKGROUND: Generalized pustular psoriasis (GPP), a rare and recurrent autoinflammatory disease, imposes a substantial burden on patients and society. Awareness of GPP in China remains limited. METHODS: This cross-sectional survey, conducted between September 2021 and May 2023 across 14 hospitals in China, included GPP patients of all ages and disease phases. Data collected encompassed demographics, clinical characteristics, economic impact, disease severity, quality of life, and treatment-related complications. Risk factors for GPP recurrence were analyzed. RESULTS: Among 127 patients (female/male ratio = 1.35:1), the mean age of disease onset was 25 years (1st quartile [Q1]-3rd quartile [Q3]: 11-44 years); 29.2% had experienced GPP for more than 10 years. Recurrence occurred in 75.6% of patients, and nearly half reported no identifiable triggers. Younger age at disease onset ( P  = 0.021) and transitioning to plaque psoriasis ( P  = 0.022) were associated with higher recurrence rates. The median diagnostic delay was 8 months (Q1-Q3: 2-41 months), and 32.3% of patients reported misdiagnoses. Comorbidities were present in 53.5% of patients, whereas 51.1% experienced systemic complications during treatment. Depression and anxiety affected 84.5% and 95.6% of patients, respectively. During GPP flares, the median Dermatology Life Quality Index score was 19.0 (Q1-Q3: 13.0-23.5). This score showed significant differences between patients with and without systemic symptoms; it demonstrated correlations with both depression and anxiety scores. Treatment costs caused financial hardship in 55.9% of patients, underscoring the burden associated with GPP. CONCLUSIONS The substantial disease and economic burdens among Chinese GPP patients warrant increased attention. Patients with early onset disease and those transitioning to plaque psoriasis require targeted interventions to mitigate the high recurrence risk.

Intravascular large B-cell lymphoma (IVLBCL), a rare subtype of non-Hodgkin lymphoma, is classified as an independent subtype of extranodal diffuse large B-cell lymphoma (DLBCL) in the 2008 World Health Organization (WHO) Classification (Turner et al., 2010). The 5th edition of the World Health Organization (WHO 2022) classification of hematolymphoid tumors retains this subtype (Alaggio et al., 2022). IVLBCL, which is characterized by neoplastic lymphocyte proliferation within the lumen of small blood vessels, tends to invade organs, such as the nervous system, skin, bone marrow (BM), and lung (D'Angelo et al., 2019; Satoh et al., 2019; Vásquez et al., 2019; Fukami et al., 2020).

Objective:To investigate the incidence of postoperative complications in Chinese patients with gastric or colorectal cancer, and to evaluate the risk factors for postoperative complications.Methods:This was a national, multicenter, prospective, registry-based, cohort study of data obtained from the database of the Prevalence of Abdominal Complications After Gastro- enterological Surgery (PACAGE) study sponsored by the China Gastrointestinal Cancer Surgical Union. The PACAGE database prospectively collected general demographic characteristics, protocols for perioperative treatment, and variables associated with postoperative complications in patients treated for gastric or colorectal cancer in 20 medical centers from December 2018 to December 2020. The patients were grouped according to the presence or absence of postoperative complications. Postoperative complications were categorized and graded in accordance with the expert consensus on postoperative complications in gastrointestinal oncology surgery and Clavien-Dindo grading criteria. The incidence of postoperative complications of different grades are presented as bar charts. Independent risk factors for occurrence of postoperative complications were identified by multifactorial unconditional logistic regression.Results:The study cohort comprised 3926 patients with gastric or colorectal cancer, 657 (16.7%) of whom had a total of 876 postoperative complications. Serious complications (Grade III and above) occurred in 4.0% of patients (156/3926). The rate of Grade V complications was 0.2% (7/3926). The cohort included 2271 patients with gastric cancer with a postoperative complication rate of 18.1% (412/2271) and serious complication rate of 4.7% (106/2271); and 1655 with colorectal cancer, with a postoperative complication rate of 14.8% (245/1655) and serious complication rate of 3.0% (50/1655). The incidences of anastomotic leakage in patients with gastric and colorectal cancer were 3.3% (74/2271) and 3.4% (56/1655), respectively. Abdominal infection was the most frequently occurring complication, accounting for 28.7% (164/572) and 39.5% (120/304) of postoperative complications in patients with gastric and colorectal cancer, respectively. The most frequently occurring grade of postoperative complication was Grade II, accounting for 65.4% (374/572) and 56.6% (172/304) of complications in patients with gastric and colorectal cancers, respectively. Multifactorial analysis identified (1) the following independent risk factors for postoperative complications in patients in the gastric cancer group: preoperative comorbidities (OR=2.54, 95%CI: 1.51-4.28, P<0.001), neoadjuvant therapy (OR=1.42, 95%CI:1.06-1.89, P=0.020), high American Society of Anesthesiologists (ASA) scores (ASA score 2 points:OR=1.60, 95% CI: 1.23-2.07, P<0.001, ASA score ≥3 points:OR=0.43, 95% CI: 0.25-0.73, P=0.002), operative time >180 minutes (OR=1.81, 95% CI: 1.42-2.31, P<0.001), intraoperative bleeding >50 mL (OR=1.29,95%CI: 1.01-1.63, P=0.038), and distal gastrectomy compared with total gastrectomy (OR=0.65,95%CI: 0.51-0.83, P<0.001); and (2) the following independent risk factors for postoperative complications in patients in the colorectal cancer group: female (OR=0.60, 95%CI: 0.44-0.80, P<0.001), preoperative comorbidities (OR=2.73, 95%CI: 1.25-5.99, P=0.030), neoadjuvant therapy (OR=1.83, 95%CI:1.23-2.72, P=0.008), laparoscopic surgery (OR=0.47, 95%CI: 0.30-0.72, P=0.022), and abdominoperineal resection compared with low anterior resection (OR=2.74, 95%CI: 1.71-4.41, P<0.001). Conclusion:Postoperative complications associated with various types of infection were the most frequent complications in patients with gastric or colorectal cancer. Although the risk factors for postoperative complications differed between patients with gastric cancer and those with colorectal cancer, the presence of preoperative comorbidities, administration of neoadjuvant therapy, and extent of surgical resection, were the commonest factors associated with postoperative complications in patients of both categories.

Before the "mesorectal" theory was proposed, the traditional anatomy believed that the "pelvirectal space" belonged to the anal canal and perirectal space, which was independent of the rectal structure, located on both sides of the rectum, above the levator ani, and below the peritoneal reflexion, and was composed of a large amount of fatty tissue filling. With the development of the theory of membrane anatomy and the clarification of the concept of "rectal mesentery", combined with the author's clinical experience, we found that the above-mentioned fat is actually the fat within the mesorectum, as well as the fat tissue of lateral lymph nodes (LLN) such as the internal iliac lymph nodes (No.263) and obturator lymph nodes (No.283) on both sides of the rectal mesentery, rather than the so-called fat tissue within the interstitial space. Therefore, the author believes that the pelvirectal space does not exist. In the anatomical location equivalent to the pelvic rectal space, there is the "superior levator ani space" based on the membrane anatomy theory. From the pelvirectal space to the superior levator anal space, it reflects our further understanding of the anatomy of the rectal mesentery.

Objective To explore the effects of transcutaneous electrical acupoint stimulation(TEAS)combined with multi-model analgesia on infrared thermal imaging characteristics and pain after total knee arthroplasty(TKA).Methods A total of 74 patients with TKA were divided into the treatment group and the control group according to random number table method,with 37 cases in each group.The control group was treated with multi-model analgesia,and the treatment group was treated with TEAS on the basis of multi-model analgesia for 30 min,once in the morning and afternoon before the patient's rehabilitation exercise 1-7 days after surgery.The infrared thermal imaging data,visual analogue scale(VAS)score,Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)score and pain threshold of the two groups were recorded and analyzed before and at different time points after operation.Results There were 2 cases dropped out in each group.Compared with before surgery,both groups had an increase in knee joint temperature on the surgical side 14 days after surgery(P<0.05),and the temperature in the treatment group was lower than that in the control group(P<0.05).The self knee temperature difference in the treatment group was lower than that in the control group 14 days after surgery(P<0.05).Compared with before surgery,the VAS score of the treatment group decreased 3 and 7 days after surgery(P<0.05),while the VAS score of the control group decreased 7 days after surgery(P<0.05);compared with the control group at 3 and 7 days after surgey,the VAS score of the treatment group was lower than that of the control group.Compared with before surgery,the WOMAC scores of both groups increased 7 days after surgery(P<0.05);after 7 days of surgery,the WOMAC score of the treatment group was lower than that of the control group(P<0.05).Compared with before surgery,the pain threshold values of both groups increased 7 days after surgery(P<0.05);compared with the control group at 3 and 7 days after surgery,the pain threshold values of the treatment group was higher than that of the control group(P<0.05).Conclusion TEAS combined with multi-model analgesia can reduce the temperature of the knee joint,relieve the pain of the operated limb,and promote the early functional recovery of the knee joint after TKA.Infrared thermal imaging technology has a certain application value in indirectly assessing the degree of postoperative pain and detecting early infection of the affected limb.

Colorectal cancer is one of the most common malignancies, with a high incidence rate. Surgical treatment, as the primary approach, has consistently garnered significant attention from surgeons. In recent years, continuous advancements in diagnostic technologies and treatment concepts have led to remarkable progress in minimally invasive therapies for colorectal cancer. From the trauma associated with open surgeries and early bowel resections to the introduction of radical tumor resection concepts, minimally invasive surgical techniques have continuously evolved. With the rise of robotic surgery and advancements in artificial intelligence in the 21st century, functional surgery has gained increasing importance. The combination of enhanced recovery principles with minimally invasive surgery has significantly improved survival outcomes and the quality of life for cancer patients. This article reviews recent advances in minimally invasive treatment concepts for colorectal cancer, drawing on past experiences, and aims to promote further progress in colorectal surgery.

Objective To observe the effects of acute normovolemic hemodilution(ANH)on target-controlled infusion(TCI)of etomidate blood drug concentration and adrenal cortical function.Methods Sixty patients who undergo elective multisegmental spine surgery,35 males and 25 females,aged 30-60 years,BMI 20-25 kg/m2,ASA physical status Ⅰ or Ⅱ,were divided into two groups using random number table method:ANH group and control group,30 patients in each group.Both groups used a target-controlled infusion of etomidate for anesthesia induction and anesthesia maintenance.In the ANH group,ANH was performed after steady anesthesia induction,ideal Hct 28％to 30％,and transfused within 1 hour after surgery;the control group was routinely treated.The dosage of etomidate was recorded.Liquid chroma-tography-tandem mass spectrometry(LC-MS/MS)was used to detect etomidate blood concentrations at the immediate postoperative,10,20,and 30 minutes postoperative periods in the two groups,and the immedi-ate moment autologous blood collected into the storage bag,preserved in the storage bag for 1 hour,and the immediate moment transfused back in the ANH group.Plasma concentrations of cortisol(Cor),adrenocorti-cotropic hormone(ACTH),and aldosterone(ALD)were measured by chemiluminescence immunoassay(CLIA)before the induction of anesthesia,immediately after the operation,and at 1 day and 2 days postop-eratively.Results There was no significant difference in the total dosage of etomidate between the two groups.Compared with the immediate postoperative period,the plasma etomidate concentration was signifi-cantly decreased 10,20,and 30 minutes after surgery(P<0.05).Compared with the control group,the concentration increased significantly 10 minutes after surgery in the ANH group(P<0.05).The plasma concentrations of etomidate were(547.8±119.4)ng/ml at the immediate moment autologous blood collected into the storage bag,(536.7±107.8)ng/ml at the preserved in the storage bag for 1 hour,and(522.8±91.7)ng/ml at theimmediatemoment transfusedbackinthe ANHgroup.Comparedwithbeforein-duction of anesthesia,the concentration of Cor and ALD immediately after the operation decreased signifi-cantly(P<0.05)and the concentration of ACTH was significantly higher(P<0.05).There were no sta-tistically significant differences in the concentrations of Cor,ALD,and ACTH between the two groups before induction of anesthesia 1 day and 2 days postoperatively.Conclusion In the orthopedic surgery of TCI eto-midate,return transfusion of collected autologous blood transiently(about 10 minutes)increases etomidate blood concentrations,the function of adrenal cortical will recover to the preoperative level within 24 hours after the operation.

Objective:To investigate the effect of combined use of midazolam and remifentanil without muscle relaxant on tracheal intubation in female patients undergoing breast surgery.Methods:A retrospective analysis was performed on 40 female patients with breast disease who underwent tracheal intubation and general anesthesia at The First Affiliated Hospital of Zhengzhou University between January 2023 and June 2023. These patients were divided into a control group ( n = 20) and an observation group ( n = 20) based on whether muscle relaxants were applied at the time of intubation. The control group received intravenous rocuronium bromide, whereas the observation group did not use muscle relaxants. Both groups were intravenously administered midazolam (0.1 mg/kg) and remifentanil (4 μg/kg) prior to tracheal intubation. The intubation conditions were evaluated based on factors such as the ease of inserting the laryngoscope and the patient's response to intubation, including coughing. Results:There were no statistically significant differences in age, height, and body mass between the two groups (all P > 0.05). The excellent rate of intubation conditions was significantly lower in the observation group compared with the control group [45% (9/20) vs. 85% (17/20), χ2 = 7.03, P = 0.008). The good rate of intubation conditions was significantly higher in the observation group compared with the control group [40% (8/20) vs. 5% (1/20), χ2 = 7.03, P < 0.05]. There was no statistically significant difference in the excellent and good rates of intubation conditions between the observation and control groups [85% (17/20) vs. 90% (18/20), χ2 = 0.23, P > 0.05]. No significant difference in intraoperative awareness score was observed between the observation and control groups [(2.59 ± 0.44) points vs. (2.61 ± 0.31) points, P > 0.05]. None of the patients in either group exhibited any episodes of arrhythmias. Furthermore, no adverse reactions such as muscle stiffness, nausea, vomiting, or skin itching were observed in either group following the surgical procedure. Conclusion:Without the use of muscle relaxants, intravenous administration of midazolam at 0.1 mg/kg and remifentanil at 4 μg/kg for tracheal intubation in female patients undergoing breast surgery can offer excellent intubation conditions, ensuring that the patient remains unconscious throughout the surgical procedure.
