By systematically combing ancient and modern literature， this paper examined Tribuli Fructus and Astragali Complanati Semen（ACS） used in the famous classical formulas from the aspects of name， origin， production area， harvesting and processing， clinical efficacy， so as to provide a basis for the development of famous classical formulas containing such medicinal materials. The results showed that the names of Tribuli Fructus in the past dynasties were mostly derived from its morphology， and there were nicknames such as Baijili， Cijili and Dujili. The name of ACS in the past dynasties were mostly originated from its production areas， and there were nicknames such as Baijili， Shayuan Jili and Tongjili. Because both of them had the name of Baijili， confusion began to appear in the Song dynasty. In ancient and modern times， the main origin of Tribuli Fructus were Tribulus terrestris， and ancient literature recorded the genuine producing areas of Tribuli Fructus was Dali in Shaanxi and Tianshui in Gansu， but today it is mainly cultivated in Anhui and Shandong. The fruit is the medicinal part， harvested in autumn throughout history. There is no description of the quality of Tribuli Fructus in ancient times， and the plump， firm texture， grayish-white color is the best in modern times. Traditional processing methods for Tribuli Fructus included stir-frying and wine processing， while modern commonly used is purified， fried and salt-processed. The ancient records of Tribuli Fructus were spicy， bitter， and warm in nature， with modern research adding that it is slightly toxic. The main effects of ancient and modern times include treating wind disorders， improving vision， promoting muscle growth， and treating vitiligo. The mainstream base of ACS used throughout history is Astragalus complanatus. Ancient texts indicated ACS primarily originated from Shaanxi province. Today， the finest varieties come from Tongguan and Dali in Shaanxi. The medicinal part is the seed， traditionally harvested in autumn. Modern harvesting occurs in late autumn or early winter， followed by sun-drying. Ancient texts valued seeds with a fragrant aroma as superior， while modern standards prioritize plump， uniform and free of impurities. Traditional processing methods for ACS included frying until blackened and wine-frying， while modern practice commonly employs purification methods. In terms of medicinal properties， the ancient and modern records are sweet and warm in nature. Due to originally classified under Tribuli Fructus， its effects were thus regarded as equivalent to those of Tribuli Fructus， serving as the medicine for treating wind disorders， additional functions included tonifying the kidneys and treating vitiligo. The present record of its efficacy is to tonify the kidney and promote Yang， solidify sperm and reduce urine， nourish the liver and brighten the eye， etc. Based on the textual research results， it is suggested that when developing the famous classical formulas of Tribuli Fructus medicinal materials， we should pay attention to the specific reference object of Baijili， T. terrestris and A. complanatus should be identified and selected， and the processing method should be in accordance with the requirements of the formulas.

Objective To explore the predictive value of CT radiomics and morphological features for the prognosis and survival in non-small cell lung cancer(NSCLC)patients.Methods The clinic data of 300 NSCLC patients(300 lesions)were downloaded from the Cancer Imaging Archive,with 210 randomly selected as the training set and 90 as the test set.According to the prognosis and survival,the patients were divided into two groups with survival period≤3 and＞3 years.3D Slicer software was used to delineate the regions of interest layer by layer in CT images,and the radiomics features were extracted from each region of interest.Both t-test and least absolute shrinkage and selection operator were utilized for radiomics feature screening.Three types of prediction models,namely radiomics model,morphological model and combined model,were constructed with Logistic regression,whose performances were evaluated using the receiver operating characteristic(ROC)curve.Results The differences in radiomics labels and mediastinal lymph node metastasis between the training set and the test set were statistically significant.For radiomics model,morphological model and combined model,the area under the ROC curve was 0.784(95%CI:0.722-0.847),0.734(95%CI:0.664-0.804)and 0.748(95%CI:0.680-0.815)in the training set,and 0.737(95%CI:0.630-0.844),0.665(95%CI:0.554-0.777)and 0.687(95%CI:0.578-0.797)in the test set,which demonstrated that radiomics model had the best diagnostic performance.Conclusion The CT radiomics model can effectively predict the prognosis and survival in NSCLC patients.

Objective:To investigate the clinical effect of composite surgery in the treatment of chronic common carotid artery occlusion(CCAO).Methods:A retrospective descriptive study was conducted. The clinical data of 7 patients with CCAO admitted to Xuanwu Hospital, Capital Medical University from October 2020 to December 2023 were collected retrospectively. There were 6 males and 1 female. The age was (66.7±10.9) years, ranging from 52 to 83 years. Outpatient or telephone follow-up were conducted after surgery, carotid artery ultrasound or computed tomography angiography were performed at 3 months, 6 months, and 1 year postoperatively to determine vascular patency. The selection of surgical methods and clinical effect were analyzed. Normally distributed measurement data were expressed as mean±standard deviation ( ± s). The measurement data of skewed distribution were expressed by M ( Q1, Q3). Count data were expressed as frequency. Results:All 7 patients were diagnosed with chronic CCAO before operation, 6 on the left and 1 on the right. 3 cases affected the middle and distal segments of the common carotid artery, 1 case affected the proximal segment, and 1 case each affected the middle and distal segments, the remaining case involves the entire common carotid artery. All the procedures were successfully performed, among which 4 cases underwent carotid endarterectomy combined with stent placement, and 3 cases did not receive stent placement after carotid endarterectomy. 1 patient developed neck hematoma after surgery and the remaining patients recovered well after surgery without any complications or deaths. The follow-up time was 13.5(4.0, 20.5) months; 1 patient was lost to follow-up, and 6 patients received effective follow-up. the common carotid artery remained unobstructed in all 6 patients, and there were no transient ischemic attacks or strokes during the follow-up period.Conclusion:Composite surgery is a safe and feasible method that can be used to treat chronic CCAO lesions, and has satisfactory short-term results.

Background and objective With further understanding and research into non-small cell lung cancer with tumours ≤2 cm in maximum diameter,segmental lung resection is able to achieve the same long-term prognosis as lobec-tomy.However,there are few studies on the prognostic effect of wedge resection on small volume invasive lung adenocarci-noma with an invasion depth of 0.5 to 1.0 cm.Therefore,this study focuses on the clinical efficacy and prognosis of wedge re-section in patients with small-volume invasive lung adenocarcinoma.Methods A retrospective analysis of the medical records of 208 patients who underwent surgery in the Department of Thoracic Surgery of the Affiliated Provincial Hospital of Anhui Medical University from February 2016 to December 2017 was made,and the postoperative pathological results confirmed small volume invasive lung adenocarcinoma.According to their surgical methods,they were divided into lobectomy group(n=115),segmentectomy group(n=48)and wedge resection group(n=45).Kaplan-Meier survival curve estimation and Cox proportional risk regression model were used to explore the influence of different surgical methods on the prognosis of patients with small volume invasive lung adenocarcinoma.Results The wedge resection group had better perioperative outcomes compared with the segmentectomy group and lobectomy group,with statistically significant differences in intraoperative bleed-ing(P=0.036),postoperative drainage(P＜0.001),operative time(P=0.018),postoperative time with tubes(P=0.001),and postoperative complication rate(P=0.006).There were no significant differences when comparing the three groups in terms of survival rate(lobectomy group vs segmentectomy group,P=0.303;lobectomy group vs wedge resection group,P=0.742;and segmentectomy group vs wedge resection group,P=0.278)and recurrence-free survival rate(lobectomy group vs segmentec-tomy group,P=0.495;lobectomy group vs wedge resection group,P=0.362;segmentectomy group vs wedge resection group,P=0.775).Univariate and multivariate survival analyses showed that consolidation tumor ratio(CTR)was the prognostic factor of overall survival and revurrence-free survival for patients with small-volume invasive lung adenocarcinoma(P＜0.05).Conclusion Wedge resection in patients with small volume invasive lung adenocarcinoma can achieve long-term outcomes similar to segmentectomy and lobectomy.When the CTR≤0.5,wedge resection is preferred in such patients.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.

Objective:To investigate the clinical characteristics and surgical treatment experience of carotid body tumor (CBT).Methods:The clinical data of 12 patients with CBT admitted to the Department of Vascular Surgery, Xuanwu Hospital, Capital Medical University from March 2013 to August 2020 were analyzed retrospectively. Among them, there were 6 males and 6 females, aged 31-83 years, with a median age of 57 years. Among the 12 patients, 2 patients were not treated surgically. The body mass index (BMI), tumor side, maximum diameter of tumor, and tumor classification, operation time, intraoperative bleeding volume, postoperative drainage volume and time, postoperative hospital stay and postoperative complications of patients undergoing surgery were recorded.Results:BMI of the 12 patients was 17.19-29.07 kg/m 2, with an average of (24.05±3.95) kg/m 2. Among the 12 patients, there were 4 tumors on the left side, 6 tumors on the right side and 2 patients had bilateral tumors. The maximum diameter of the tumor was 1.7-8.7 cm, with an average of (4.05 ± 1.89) cm. Among the 2 patients with bilateral tumors, 1 patient underwent staged resection within 9 months and 1 patient only removed the larger tumor. A total of 10 patients underwent surgical resection. All excised tumors were confirmed histopathologically to be paraganglioma. The average operation time and the amount of bleeding was(164.73 ± 74.39)min and 341.82 mL respectively. The drainage time was 1-3 d, with an average of (1.73 ± 0.65) d. The cumulative drainage volume was 22-237 mL, with an average of (77.18 ± 57.47) mL. Classification of 11 surgically resected tumors: 3 patients (3/11, 27.3%) were Shamblin Ⅰ, 7 patients (7/11, 63.6%) were Shamblin Ⅱ and 1 patient (1/11, 9.1%) were Shamblin Ⅲ. There were 1 patient of hematoma and 1 patient of acute cerebral infarction after operation. One patient with decrease in muscle strength of right limb, other surgical patients complained no complications such as stroke and cranial nerve injury when discharged. Patients undergoing surgery were hospitalized for 8-20 days, with an average of (13.36 ± 3.61) d. Conclusions:CBT is a rare paraganglioma in clinic. Surgical resection is an effective method to treat CBT. Careful operation should be carried out to avoid serious complications such as wound hematoma, cranial nerve injury and ischemic stroke.

OBJECTIVE：To in vestigate the effects of dexmedetomidine （Dex）on SIRT 1/Akt/GSK3β/β-catenin signaling pathway in cerebral injury of sepsis model rats ，and explore the mechanism of its protecitve effect on cerebral injury. METHODS ： A total of 80 male SD rats were randomly divided into sham operation group （Sham group ），sepsis group （CLP group ），CLP+Dex group（10 μg/kg Dex），CLP+Dex+Sirtinol group （10 μg/kg Dex+2 μL/100 g SIRT 1 inhibitor sirtinol ），with 20 mice in each group. Two hours before modeling ，CLP+Dex+Sirtinol group was injected with sirtinol via lateral ventricle. Sepsis model was induced by cecal ligation and perforation in each group （in sham group ，only operation was performed but no ligation was performed）. At 0，3，6 h after modeling ，CLP+Dex group and CLP+Dex+Sirtinol group were given Dex （10 μg/kg） intraperitoneally，Sham group and CLP group were given constant volume of normal saline intraperitoneally. Cerebral tissue water content，Evans blue （EB）content，apoptosis in cerebral cortex ，the levels of IL- 1β and TNF-α in cerebral tissue as well as the protein expression of SIRT 1，p-Akt，p-GSK3β and β-catenin in hippocampus were detected 24 h after last medication. RESULTS ： Compared with Sham group ，cerebral tissue water content ，EB content ，the number of apoptotic cells in cerebral cortex as well as the levels of IL- 1β and TNF-α in cerebral tissue were increased significantly（P＜0.05），while the protein expression of SIRT 1， p-Akt，p-GSK3β and β-catenin in hippocampus were decreased significantly （P＜0.05）. Compared with CLP group ，cerebral tissue water content ，EB content ，the number of apoptotic cells in cerebral cortex as well as the levels of IL- 1β and TNF-α in cerebral tissue were decreased significantly in CLP+Dex group （P＜0.05），while the protein expression of SIRT 1，p-Akt，p-GSK3β and β-catenin in hippocampus were increased significantly （P＜0.05）. Sirtinol could significantly reverse the above-mentioned cerebral protection and factor regulation effects of Dex （P＜0.05）. CONCLUSIONS ：Dex can protect the cerebral tissue of sepsis model rats，which may play an anti-inflammatory and anti-apoptotic role by activating SIRT 1/Akt/GSK3β/β-catenin signaling pathway ，so as to reduce cerebral edema ，protect blood-brain barrier and reduce cerebral injury.

Objective:To explore the method and effect of endovascular treatment to innominate artery stenosis or occlusion.Methods:The data of 11 patients with stenosis or occlusion of innominate artery from January 2014 to November 2019 at Xuanwu Hospital of Capital Medical University were collected. All patients received endovascular treatment. We summarized the changes of clinical symptoms, surgical methods, perioperative complications, stent patency, and analyzed the changes in systolic blood pressure and peak blood flow velocity on the involving side.Results:All 11 patients underwent endovascular treatment. The surgical technique success rate was 100%. All patients were followed up. The follow-up time was 4-69 months, with an average of (30.1±23.4)months. 2 patients used cerebral umbrella during the operation. 1 patient was performed ipsilateral carotid endarterectomy, 1 patient underwent contralateral carotid stent implantation, 1 patient was diagnosed as severe stenosis of the innominate artery and left common carotid artery, and an innominate artery stent implantation was performed at one stage, left common carotid artery stent implantation was performed after half a year. We done operation from the femoral artery puncture approach (6 patients), brachial artery puncture approach (2 patients), axillary artery and femoral artery puncture approach (1 patients), and right common carotid artery and the femoral artery puncture approach (2 patients). 3 patients had in-stent restenosis at 6, 7and 12 months after stenting, respectively. 1 patient underwent balloon dilatation, and 2 patients underwent re-stent implantation. We have not do further intervention to 1 case of in-stent occlusion occurred 14 months after the stenting, for the clinical symptoms did not improve significantly. The clinical re-intervention rate in this group was 3/11, and the primary patency rate was 7/11. The secondary patency rate was 10/11. The symptoms of 10 patients were relieved and the weakness of right upper extremity was not significantly changed in 1 patient. No puncture point complications occurred in all patients, and no cerebral infarction occurred during the perioperative period. There were statistically significant differences in systolic blood pressure, blood pressure difference and peak blood flow velocity before and after the operation ( P<0.05). Conclusions:Endovascular treatment of innominate arterial stenosis or occlusion was safe and effective, and the appropriate surgical approach and plan should be selected according to the lesion characteristics and the whole body conditions.

Objective: To investigate the effect of endovascular treatment of cerebral infarction with right aortic arch and Kommerell's diverticulum. Methods: Retrospective analysis was done to assess the treatment effect of a case from vascular surgery, Xuanwu Hospital of Capital Medical University. This case was diagnosed as cerebral infarction with right aortic arch and Kommerell's diverticulum. Results: One month after the treatment of cerebral infarction, we successfully used the thoracic aortic stent to isolate the Kommerell's diverticulum. There were no operative complications occurred. The stent had good shape and smooth blood flow was seen in the stent. Conclusions Endovascular treatment to cerebral infarction with right aortic arch and Kommerell's diverticulum is safe and feasible, and the clinical outcome requires further long-term follow-up.

Objective To compare the clinical curative effects of PTA and simple pharmacotherapy for intrapopliteal artery ischemic disease.Methods Seventy-three patients with intrapopliteal artery ischemic disease were divided into PTA group (n=37) and pharmacotherapy group (n=36).Their ABI,claudication distance,vascular patency,rest pain and amputation rate were recorded and analyzed with SPSS 22.0 at months 1,3,6,12,18 and 24 respectively before and after treat ment.The vascular patency and amputation rate were analyzed according to the Kaplan-Meier curve.Results The ABI was higher in PTA group than in pharmacotherapy group during the 1-24 months following up period after treatment,and was still higher in PTA group than in pharmacotherapy group at month 24 after treatment (0.640±0.238 vs 0.500±0.152,P=0.038).The claudication distance was shorter and the rest pain was milder in PTA group than in pharmacotherapy group at months 1 and 3,and at months 1-18 respectively (P＜0.05,P＜0.01).No significant difference was found in amputation-free survival curves between the two groups (Plogrank =0.618).Conclusion The symptom improvement of PTA is better than that of pharmacotherapy for patients with severe rest pain or severe intermittent claudication.
