Based on advancements in modern medical research regarding the intricate connection between the endocrine and exocrine functions of the pancreas， as well as the relationship between pancreatic functions and traditional Chinese medicine （TCM） spleen system， this paper discussed the categorization of the pancreas. It is proposed that the pancreas is neither a true zang organ nor a fu organ， but possessed the attributes of an extraordinary fu-organ and can be classified under the spleen. The spleen governs transportation and transformation， ascent of the clear and dispersion of essence， which encompasses the endocrine and exocrine functions， and pancreatic enzymes and glucose-regulating hormones form the material basis for the spleen's function of dispersing essence. Diseases of the pancreas exhibit characteristics of both zang-organ deficiency and fu-organ excess， so treatment should simultaneously supplement zang-organ disease and regulate fu-organ disease when pancreas showing endocrine and exocrine co-morbidities， with focus on restoring the pancreas （spleen）'s dispersing essence function. Therapeutic strategies include supplementing spleen qi， nourishing spleen yin to strengthen spleen earth， unblocking spleen collaterals， raising spleen yang， and removing spleen turbidity to support the spleen's dispersing essence function， so as to replenish the essential qi of zang-fu organs， ensure their distribution throughout the body， and improve the endocrine and exocrine functions of the pancreas.

Objective:To compare the clinical outcomes of immediate breast reconstruction using latissimus dorsi flap with implant versus mesh with implant based on BREAST-Q evaluation.Methods:From the clinical database of the First Affiliated Hospital of Nanjing Medical University, the patients who underwent immediate breast reconstruction after total mastectomy from January 2020 to December 2023 were selected as the research subjects. All breast reconstruction surgeries were performed by the same surgeon. Patients were divided into two groups according to surgical methods: the latissimus dorsi muscle flap combined with implant immediate breast reconstruction group (LD group) and the mesh combined with implant immediate breast reconstruction group (mesh group). Patients were followed up in outpatient clinics or by telephone one year after surgery. The BREAST-Q was used to evaluate the surgical outcomes of both groups from four dimensions: psychosocial well-being, sexual well-being, chest-physical well-being, and breast satisfaction. The score range for each dimension was 0-100, with higher scores indicating greater patient satisfaction with quality of life and surgical outcomes. Statistical analysis was performed using SPSS 22.0 software. Normally distributed measurement data were expressed as Mean ± SD, and comparisons between the two groups were performed using independent sample t-test. Count data were expressed as number of cases and percentages, and comparisons between groups were performed using chi-square test or Fisher’s exact test. P<0.05 was considered statistically significant. Results:A total of 123 patients were included, with 59 patients in the LD group and 64 patients in the mesh group. In the LD group, the mean age was (37.7±7.0) years, body mass index (BMI) was (22.6±2.6) kg/m 2, and clinical tumor staging showed 2, 22, 30, and 5 cases for stages 0, Ⅰ, Ⅱ, and Ⅲ, respectively. In the mesh group, the mean age was (39.1±7.0) years, BMI was (22.6±2.8) kg/m 2, and clinical tumor staging showed 1, 25, 38, and 0 cases for stages 0, Ⅰ, Ⅱ, and Ⅲ, respectively. There were no statistically significant differences between the two groups in baseline characteristics including age, BMI, and clinical tumor staging (all P>0.05). One year after surgery, the BREAST-Q result showed no statistically significant differences between the LD group and mesh group in psychosocial well-being [(83.0±19.8) points vs. (80.8±19.3) points] and sexual well-being [(62.1±30.4) points vs. (65.8±25.6) points] (all P>0.05). However, the LD group had lower chest-physical well-being scores than the mesh group [(40.6±9.7) points vs. (45.1±9.6) points, P<0.05], while breast satisfaction scores were higher in the LD group than in the mesh group [(68.0±17.8) points vs. (59.8±12.6) points, P<0.01]. Conclusion:Immediate breast reconstruction by both latissimus dorsi flap with implant and mesh with implant can improve patients’ psychosocial and sexual well-being by enhancing breast appearance. However, LD technique provides better breast satisfaction, while the mesh technique offers advantages in physical well-being of the chest wall and upper body. Surgeons should select the most appropriate breast reconstruction technique based on patients’ anatomical conditions, treatment history, and individual needs to optimize postoperative quality of life and satisfaction.

ObjectiveThe glycosidic linkage structural characteristics of polysaccharides from Pinelliae Rhizoma（PR） and its processed products were analyzed by sugar spectrum， high performance thin layer chromatography（HPTLC）， fluorescence-assisted carbohydrate gel electrophoresis（PACE） based on partial acid hydrolysis and specific glycosidase hydrolysis， and the antioxidant activities of polysaccharides before and after hydrolysis（enzymolysis） were compared. MethodPolysaccharides from PR and its processed products were extracted by ultrasound extraction， starch was hydrolyzed by α-amylase， and small molecules below 3 kDa were removed by ultrafiltration. The purified polysaccharides were prepared by hydrolysis of acid and five different specific glycosidases， and the hydrolysates were analyzed by HPTLC and PACE. The antioxidant capacity of polysaccharides was analyzed by 2，2′-azino-bis（3-ethylbenzthiazoline-6-sulfonic acid）（ABTS） and 2，2-diphenyl-1-picrylhydrazyl（DPPH） free radical scavenging experiment before and after different hydrolysis. ResultThrough HPTLC and PACE analysis， it was found that polysaccharides from PR and its processed products could be hydrolyzed by β-galactosidase， β-mannase， cellulase and pectinase， but hardly hydrolyzed by glucanase， indicating that the polysaccharides contained β-galactopyranoside bond， β-1，4-mannoside bond， β-1，4-glucoside bond and α-1，4-galacturonic acid glycosidic bond. In vitro antioxidant experiments showed that the ABTS radical scavenging capacity of the polysaccharides from PR and its processed products was weakened after acid hydrolysis and pectinase enzymatic hydrolysis， while the ABTS radical scavenging capacity was enhanced after enzymatic hydrolysis with cellulase， β-galactosidase， and β-mannase. And after different hydrolysis， the DPPH free radical scavenging capacity of polysaccharides from PR and its processed products was all significantly enhanced. ConclusionThe glycosidic linkage structural characteristics of polysaccharides from PR and its processed products was analyzed by sugar spectrum in this paper， and the relationship between glycosidic bond types and their antioxidant activity was clarified through in vitro antioxidant experiments， which is beneficial for further elucidating the material basis of the related efficacy of PR and its processed products， and providing new ideas and methods for analyzing the structural characteristics of polysaccharides in Chinese medicines.

Objective     To evaluate the predictive performance of the geometric characteristics, centerline (CL) of pulmonary nodules for prognosis in patients with surgically treatment in the National Lung Screening Trial (NLST). Methods    CT images of 178 patients who underwent surgical treatment and were diagnosed with non-small cell lung cancer (NSCLC) in the low-dose CT (LDCT) cohort from the NLST image database were selected, including 99 males and 79 females, with a median age of 64 (59, 68) years. CT images were processed using commercial software Mimics 21.0 to record the volume, surface area, CL and the area perpendicular to the centerline of pulmonary nodules. Receiver operating characteristic (ROC) curve was used to compare the predictive performance of LD, AD and CL on prognosis. Univariate Cox regression was used to explore the influencing factors for postoperative disease-free survival (DFS) and overall survival (OS), and meaningful independent variables were included in the multivariate Cox regression to construct the prediction model. Results    The area under the curve (AUC) of CL for postoperative recurrence and death were 0.650 and  0.719, better than LD (0.596, 0.623) and AD (0.600, 0.631). Multivariate Cox proportional risk regression analysis showed that pulmonary nodule volume (P=0.010), the maximum area perpendicular to the centerline (MApc)(P=0.028) and lymph node metastasis (P<0.001) were independent risk factors for DFS. Meanwhile, age (P=0.010), CL (P=0.043), lymph node metastasis (P<0.001), MApc (P=0.022) and the average area perpendicular to the centerline (AApc) (P=0.016) were independently associated with OS. Conclusion    For the postoperative outcomes of NSCLC patients in the LDCT cohort of the NLST, the CL of the pulmonary nodule prediction performance for prognosis is superior to the LD and AD, CL can effectively predict the risk stratification and prognosis of lung cancer, and spheroid tumors have a better prognosis.

Objective     To evaluate the security and clinical value of the combination of three-dimensional computed tomography-bronchography and angiography (3D-CTBA) and indocyanine green (ICG) staining in video-assisted thoracic surgery (VATS) segmentectomy. Methods     The clinical data of 125 patients who received VATS segmentectomy from January 2020 to January 2021 in our hospital were retrospectively analyzed. There were 40 (32.0%) males and 85 (68.0%) females with an average age of 54.8±11.1 years. Results     The procedure was almost identical to the preoperative simulation. All intersegment planes were displayed successfully by ICG reverse staining method. There was no allergic patient. A total of 130 pathological specimens were obtained from the 125 patients. The mean operation time was 126.8±41.9 min, the time of first appearance of fluorescence was 22.7±4.9 s, the mean mark time was 65.6±20.3 s, the median blood loss was 20.0 (10.0-400.0) mL, the postoperative hospital stay was 5.6 (4.0-28.0) d, and the postoperative retention of chest tube time was 3.2 (2.0-25.0) d. Pathological results showed that microinvasive adenocarcinoma was the most common type (38.5%, 50/130), followed by invasive adenocarcinoma (36.9%, 48/130); there were 3 metastatic tumors (3/130, 2.3%). Conclusion     The combination of 3D-CTBA and ICG reverse staining is proved to be a safe, necessary and feasible method. It solves the difficult work encountered in the procedure of segmentectomy, and it is worth popularizing and applying in clinic.

Objective:Taking emergency department (ED) as a starting point, to analyze the epidemiological characteristics and mortality risk factors of sepsis, and to provide evidences for ED to carry out the strategy of "three early and two lower" for sepsis.Methods:Based on the ED and inpatient medical record management information platform of Tianjin Medical University Gernal Hospital, adult ED patients with sepsis from January 1, 2017 to December 31, 2020 were included according to the third international consensus definitions for sepsis and septic shock in 2016 and the consensus of Chinese experts on early prevention and blocking of sepsis in 2020. The epidemiological characteristics of patients were retrospectively analyzed. Chi-square test was used to compare the difference of age, sex, hospitalization times, length of stay, hospitalization cost and infection location between dead patients and survival patients, and a stepwise logistic regression model was used to analyze the influencing factors of mortality in hospitalized patients with ED sepsis.Results:A total of 7 494 patients with sepsis in ED were included in this study, and the annual and monthly component ratios varied from 3.8‰ to 6.1‰ and 2.0‰ to 9.0‰, respectively. The main characteristics of patients with sepsis in ED were as follows: 40-69 years old (46.0%), male (59.0%), mostly diagnosed with sepsis (96.8%), mainly treated with urban health insurance (59.6%), and ED diagnosis and treatment fees of 2 000-8 000 Yuan (51.1%). The mortality of hospitalized patients with ED sepsis was 24.4% and that of hospitalized patients with septic shock was 28.8%. The main characteristics of hospitalized patients with ED sepsis were as follows: most of them were male (56.2%) patients over 70 years old (56.0%), most of them were diagnosed with sepsis (94.0%) and hospitalized for the first time (76.0%), the median hospitalization time was 15 d, most of them were hospitalized under urban health insurance (65.2%), and the median hospitalization fees was 47 000 Yuan. The risk factors of death were influenced by age and length of stay. Patients aged 70 years or older had a higher risk of death than those aged from 18 to 39 years, and patients with a length of stay of more than 7 d had a lower risk of death than those with a length of stay of shorter than 7 d. The primary infection focus were mainly respiratory and urinary systems, while the death rate of patients with hematological and abdominal infections was relatively high, and the difference was statistically significant ( P<0.01). Respiratory and abdominal infections were risk factors for death in patients with ED sepsis. Conclusions:The composition ratio of sepsis in ED patients is not regular in time, so vigilance of sepsis in elderly men and patients with respiratory system, blood system, urinary system and abdominal infections should be constantly raised. Patients with sepsis who are older, hospitalized more frequently, hospitalized for a shorter time, and infected in the respiratory system or abdomen have a higher risk of death.

Objective:To investigate the effectiveness and safety of early combined with tirofiban in the treatment of elderly patients with acute ischemic stroke after intravenous thrombolysis with alteplase.Methods:Elderly (60-75 years old) patients with acute ischemic stroke received intravenous alteplase thrombolysis in the Department of Neurology, Traditional Chinese Medicine Hospital of Huangdao District, Qingdao from January 2018 to May 2020 were enrolled prospectively. According to whether tirofiban is combined or not, they were divided into tirofiban group and non-tirofiban group. Tirofiban was pumped intravenously 2 h after intravenous thrombolysis, first 0.4 μg/(kg·min) for 30 min, then 0.1 μg/(kg·min) for 24 h. The efficacy endpoints included National Institutes of Health Stroke Scale (NIHSS) score at 7 d after treatment and modified Rankin Scale (mRS) score at 90 d after onset. 0-2 was defined as good outcome, and >2 was defined as poor outcome. The safety endpoints included the incidence of hemorrhagic transformation, symptomatic intracranial hemorrhage (sICH) and mortality within 90 days after onset.Results:A total of 124 patients with acute ischemic stroke were enrolled. The median age was 68 years (range, 60-75 years). There were 73 males (58.9%) and 51 females (41.1%). There were 62 patients (50%) in the tirofiban group and 62 (50%) in the non-tirofiban group. The median baseline NIHSS score was 14. Hemorrhagic transformation occurred in 7 patients (5.6%), of which 2 were sICH (1.6%). The follow-up at 90 d after onset showed that 68 patients (54.8%) had a good outcome, 56 (45.2%) had a poor outcome, of which 4 (3.2%) died. The NIHSS score at 7 d after treatment (5.52±4.79 vs. 7.35±3.80; t=2.357, P=0.020) and the rate of good outcome at 90 d after onset (64.5% vs. 45.2%; χ2=4.689, P=0.030) in the tirofiban group were significantly better than those of the non-tirofiban group, and there were no significant differences among the incidence of hemorrhagic transformation (4.8% vs. 6.5%; P=1.000), sICH (1.6% vs. 1.6%; P=1.000), and 90 d mortality (3.2% vs. 3.2%; P=1.000). Conclusion:After intravenous thrombolysis with alteplase, the early combined treatment with tirofiban in elderly patients with acute ischemic stroke can significantly improve the efficacy and outcome, and will not increase the risk of hemorrhagic transformation, sICH and death.

BACKGROUND: The good prognosis of lepidic predominant invasive adenocarcinoma (LPA) and adenocarcinoma in situ (AIS)/microinvasive adenocarcinoma (MIA) in the pathological subtypes of early lung adenocarcinoma is similar, and the means to distinguish LPA from non-LPA is urgently needed in clinical practice. This study intends to analyze the correlation between positron emission computed tomography (PET)/computed tomography (CT) maximal standard uptake value (SUVmax) with CT three-dimensional reconstruction parameters and the pathological subtypes of early lung adenocarcinoma with part-solid nodules (PSNs) in preoperative imaging. METHODS: The data of early lung adenocarcinoma patients who underwent anatomical pneumonectomy at the Department of Thoracic Surgery of Northern Jiangsu People's Hospital from January 2016 to January 2019 retrospectively analyzed and subsolid nodules on imaging were showed. All patients with enhanced chest CT and PET/CT data can be obtained completely, using Mimics software to perform three-dimensional reconstruction to obtain tumor volume, 3-dimensional mean-CT value (3Dm-CT) of tumor and SUVmax, using SPSS 25.0 for statistical analysis and GraphPad Prism 8.3.0 for drawing receiver operating curve (ROC). P<0.05 indicates that the difference is statistically significant. RESULTS: 67 patients were included in this study. All patients were divided into two groups according to different pathological subtypes. AIS, MIA and LPA in invasive adenocarcinoma (IAC) were in the low-risk group, 28 cases (41.8%), and the remaining non-LPA were in high-risk group, 39 cases (58.2%). SUVmax (t=3.153, P=0.002), tumor volume (t=3.331, P=0.001), solid/ground glass component volume (t=2.74, P=0.006)/(t=3.127, P=0.002) and 3Dm-CT of solid/ground glass component (t=3.655, P<0.001)/(t=7.082, P<0.001) between the two groups were all statistically significant. ROC curve prompts: SUVmax [area under curve (AUC)=0.727], tumor volume (AUC=0.740), ground glass component volume (AUC=0.725), 3Dm-CT of solid components (AUC=0.763), 3Dm-CT of ground glass components (AUC=0.756) have the best predictive performance. The above-mentioned covariates with AUC>0.7 were included in the multivariate ROC curve analysis, and the joint predictor (AUC=0.835) was obtained with medium or above predictive value. CONCLUSIONS PET/CT SUVmax and CT three-dimensional reconstruction parameters have a significant correlation with the different pathological subtypes of early lung adenocarcinoma with PSNs in imaging. The combination of SUVmax, tumor volume, ground glass component volume and 3Dm-CT of solid/ground glass component CT value has certain value in identifying the pathological subtype of early stage lung adenocarcinoma with PSNs nodules in imaging.
