ObjectiveHistorically documented Zhejiang Atractylodis Macrocephalae Rhizoma（Baizhu） possesses premium characteristics such as phoenix-like head and crane-like neck， pronounced sweetness， and fragrant aroma. However， its current market circulation is low， and the processed products with Zhejiang-style characteristics are at the risk of being lost. This study aims to preserve the ancient Zhejiang-style processing techniques and evaluate them using modern scientific methods. MethodsMultidimensional intelligent sensory evaluation was used to digitally characterize the "quality-structure" of the external appearance of nine-steamed and nine-processed Baizhu medicinal materials（intermediate processed products） and the "odor-taste" of the internal quality of its decoction pieces（slices）， and the appearance parameters were digitally characterized by colorimeter， texture analyzer， electronic nose and electronic tongue， the chemical composition was analyzed via ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS）. Then， cluster analysis on the differences in odor between the medicinal materials（intermediate processed products） and decoction pieces（slices） of nine-steamed and nine-processed Baizhu was conducted， as well as the differences in taste between water-soluble and alcohol-soluble extracts of the decoction pieces（slices）， and the correlation analysis of chroma value-alcohol-soluble extract content-component response value. ResultsThe nine-steamed and nine-processed Baizhu had a dark brown to black epidermis， a brownish-yellow to brownish-gray cross-section， a slightly tough texture， a faint odor， and a slightly sweet， bitter and pungent taste. Texture analyzer measurements revealed minimal adhesion and maximum recovery in the middle section of the characteristic processed Baizhu， consistent with the processing endpoint of thorough steaming and cooking. The head section showed the highest internal hardness， elasticity and chewiness， indicating a denser texture in this area. The electronic nose sensor could clearly distinguish the difference between the medicinal materials and its decoction pieces， with a more significant clustering effect at 60 ℃ for 30 minutes compared to ambient temperature headspace for 2 hours， highlighting the significant impact of the baking degree before slicing on the quality. The electronic tongue taste signal map clearly distinguished the differences between water-soluble and alcohol-soluble extracts of nine-steamed and nine-processed Baizhu decoction pieces， and the addition of auxiliary materials during processing could enhance its alcohol-soluble extract content. A total of 82 chemical components were identified in the characteristic processed Baizhu. After processing， the contents of 58 components increased， while 24 components decreased. Correlation analysis revealed significant negative correlations（P<0.01） between ethanol-soluble extract content and colorimetric values of brightness（L^*）， yellow-bule value（b^*）， and total color difference（E^*_ab）. E^*_ab showed marked negative correlations（P<0.05） with the response values of isochlorogenic acid A and C. ConclusionThis study establishes a modern intelligent sensory evaluation model for multidimensional holographic characterization of nine-steamed and nine-processed Baizhu， clarifying the correlation between increased isochlorogenic acid content and the visual color appearance after different steaming cycles， as well as its intrinsic alcohol-soluble extracts. This provides a reference for quality evaluation and processing standards of the Zhejiang-style characteristic processed products.

Objective:To investigate the clinical efficacy of radical gastrectomy with mesan-gientization via the inferior margin of the pancreas approach (GMIP).Methods:The retrospective cohort study was conducted. The clinicopathological data of 255 patients of Siewert Ⅱ and (or) Ⅲ adenocarcinoma of esophagogastric junction (AEG) who were admitted to Cancer Hospital Affiliated to Shanxi Medical University from March 2024 to March 2025 were collected. There were 191 males and 64 females, aged (62 ±7)years. Of 255 patients, 152 cases undergoing GMIP were allocated into the mesangientization radical resection group, 103 cases undergoing D 2 radical resection of gastric cancer were allocated into D 2 radical resection group. Observation indicators: (1) surgical and post-operative situations; (2) lymph node dissection status. Comparison of measurement data with normal distribution between groups was conducted using the t test. Comparison of measurement data with skewed distribution between groups was conducted using the Wilcoxon test. Comparison of count data between groups was conducted using the chi-square test or corrected chi-square test. Compari-son of ordinal data was conducted using the rank sum test. Results:(1) Surgical and postoperative situations. In the mesangientization radical resection group, the time of lymph node dissection was (115±14)minutes, volume of intraoperative blood loss was (81±37)mL. In the D 2 radical resection group, the above indicators were (97±13)minutes, (104±39)mL, respectively. There were significant differences in the above indicators between the two groups ( t=-8.68, -4.64, P<0.05). In the mesan-gientization radical resection group, the total number of examined lymph node was 40.00(10.00), the number of lymph node dissected (the total number of each group) was 29.00(5.00), the number of lymph node metastasis (the total number of each group) was 2.00(1.00). In the D 2 radical resection group, the above indicators were 27.00(9.00), 8.00(4.00), 1.00(1.00), respec-tively. There were significant differences in the above indicators between the two groups ( Z=-10.68, -13.57, -6.80, P<0.05). (3) Lymph node dissection status. There were significant differences in number of lymph node dissected of No.14v, 12a, 12p, 11d, 11p, 10, postgastric, 9, 8a, 8p lymph node between the mesangientization radical resection group and the D 2 radical resection group ( P<0.05). There were significant differences in number of lymph node metastasis of No.11d and postgastric lymph node between the mesangientization radical resection group and the D 2 radical resection group ( P<0.05). Conclusion:Compared with D 2 radical resection, the GMIP for Siewert Ⅱ or Ⅲ AEG has less volume of intraoperative blood loss and more complete lymph node dissection.

Objective To evaluate the efficacy of minimally invasive neuroendoscopy combined with intraventricular drainage in the treatment of intraventricular hemorrhage.Methods A retrospective analysis was conducted on the clinical data of 88 patients with intraventricular hemorrhage who underwent surgical treatment from January 2018 to December 2023.All patients received bilateral ventricular indwelling external drainage tubes.Among them,37 cases were included in the endoscopy group.The bleeding side or side with more blood accumulation underwent a midline fistula.With the assistance of neuroendoscopy,the intraventricular blood clots were removed and a ventricular drainage tube was inserted.The contralateral ventricle was punctured and a ventricular drainage tube was inserted;The remaining 51 cases were included in the drainage group,in which bilateral ventricular drainage tubes were placed according to the traditional intraventricular drainage protocol.Results There was no significant statistical difference(P>0.05)between the endoscopic group and the drainage group in terms of mortality rate(10.8%vs.13.7%),rebleeding rate(8.1%vs.11.8%,P=0.576),intracranial infection rate(10.8%vs.17.6%,P=0.372),and hydrocephalus rate(10.8%vs.23.5%,P=0.166).Similarly,no significant statistical difference was found in the total hospitalization cost between the endoscopy group and the drainage group[(90700±73000)yuan vs.(99500±66000)yuan]and the GOS score during the 6-month follow-up(3.16±1.14 vs 3.02±1.12)showed(P>0.05).However,the postoperative GCS score improvement was significantly better in the endoscopic group than in the drainage group[2.00(2.00,4.00)vs.1.00(0.00,3.00),P=0.002].The duration of the extracranial drainage catheter placement was significantly shorter in the endoscopic group than in the drainage group[(7.16±2.99)days vs.(10.12±3.93)days,P<0.001].Conclusion Neuroendoscopy-assisted evacuation of intraventricular hemorrhage facilitates effective hematoma clearance,reduces the duration of ventricular drainage catheterization,and may contribute to improved patient outcomes.

Objective To explore the long-term efficacy of percutaneous pulmonary valve implantation(PPVI)and the durability of the domestic self-expanding Venus P valve.Methods A total of 8 patients with post-surgical right ventricular outflow tract(RVOT)dysfunction,who were admitted to hospital from October 2014 to July 2016 and deemed anatomically suitable for PPVI with self-expanding valve,were included prospectively.Clinical,imaging,procedural and follow-up data were analyzed.The survival rates,perioperative and long-term complication rates,long-term efficacy of PPVI,and long-term function of Venus P in 8 patients were evaluated.The immediate procedural results were evaluated by clinical implant success rate,which is defined as successful valve implantation with echocardiography-assessed pulmonary regurgitation＜moderate and peak trans-pulmonary pressure gradient＜40 mmHg.Results A total of 8 patients were included,with 7 females,aged 14 to 36 years.The initial diagnosis included post-surgical Tetralogy of Fallot(5 cases),post-surgical Trilogy of Fallot(1 case),post-surgical Quadricuspid pulmonary valve stenosis(1 case)and post-surgical Double-Outlet Right Ventricle(1 case).The indications of PPVI included RVOT-pulmonary obstruction and regurgitation(1 case)and isolated regurgitation(7 cases).Clinical implant success was achieved in all of the 8 patients with firmly fixed valve,and there were no such complications as valve detachment,displacement or stent fracture.All patients experienced significant symptom relief after the procedure.The right ventricular end-diastolic volume index(RVEDVi)measured by CMR 6 months after PPVI showed a significant decrease compared to preprocedural values[(89.99±13.85)ml/m2 vs.(144.93±11.28)ml/m2,P=0.001].Postoperative pulmonary regurgitation were significantly improved or disappeared in all patients,and there was no statistically significant difference in the average peak pressure gradient measured by echocardiogram between preoperative and the latest follow-up[(23.25±8.39)mmHg vs.(18.75±6.28)mmHg,P=0.210].Over an average follow-up period of(9.25±0.71)years,1 case of infective endocarditis occurred 5 years after PPVI.During the follow-up,no death,deterioration of heart failure,malignant arrhythmia or other serious complications were observed.All patients completed 8-year follow-up,and 3 completed 10-year follow-up.All patients were graded as NYHA functional class one at the latest follow-up.Conclusions PPVI using the domestically produced self-expanding Venus P is safe and feasible for the treatment of patients with post-surgical RVOT dysfunction and suitable anatomy.Our study confirms the long-term efficacy and durability of Venus P from multiple perspectives,and no severe stent fracture occurred without pre-stent implantation in the native RVOT.

Objective To compare the effects of different doses of adenine(ADE)by oral gavage in a mouse model of renal fibrosis(RF),and to provide a more suitable mouse model for further RF research.Methods Thirty C57BL/6J Nifdc mice were divided randomly into a control group,low-dose ADE group(ADE-L group,50 mg/kg),and high-dose ADE group(ADE-H group,100 mg/kg),and the general condition,mortality,and body mass changes of the mice were observed.Serum creatinine(CREA),blood urea nitrogen(BUN),and uric acid(UA)were measured on day 30 to evaluate renal function.Histopathological changes in kidney tissues were observed by hematoxylin-eosin(HE)and Masson staining,and expression levels of fibronectin(FN),collagen Ⅰ(COL Ⅰ),and alpha smooth muscle actin(α-SMA)in kidney tissues were detected by Western Blot.Results The cumulative mortality rates in the ADE-L and ADE-H groups were 91.7％and 58.3％,respectively.The body mass of mice in the ADE-L group was similar to that in the control group(P＞0.05),but the body mass of mice in the ADE-H group was significantly lower than that of mice in the control and ADE-L groups from day 3 to day 30(P＜0.001).Day 30 CREA and BUN levels in the ADE-L group were similar to those in the blank group,but CREA and BUN levels were significantly increased in the ADE-H group(P＜0.001).There were no significant differences in UA levels among all groups.Inflammatory infiltration and tubular dilatation were observed in the ADE-L group on day 30,accompanied by tubular epithelial necrosis,while crystal accumulation in the tubular lumen and interstitium was observed in the ADE-H group,and the degree of interstitial fibrosis was significantly higher than in the control group(P＜0.01).Expression levels of interstitial fibrosis-related proteins in the ADE-H group on day 30 were significantly higher than in the control and ADE-L groups(P＜0.05,P＜0.01 or P＜0.001).Conclusions Both 50 and 100 mg/kg of ADE can be used to establish a mouse model of RF,with different doses leading to varying degrees of renal injury.Mice in the ADE-L group developed mild interstitial fibrosis on day 30,while mice in the ADE-H group developed moderate to severe interstitial fibrosis.

Objective:To seek any correlation between hypoesthesia and sensory disturbance to motor function among stroke survivors.Methods:One hundred and two stroke survivors with hyperalgesia were treated with sinusoidal alternating current at 2000Hz, 250Hz or 5Hz to stimulate the fingers and toes on their healthy and hemiplegic sides. Current perception thresholds (CPTs) and pain tolerance thresholds (PTTs) were recorded. The correlation between the degree of sensory disturbance in the hemiplegic limb and muscle strength was explored.Results:①The degree of sensory impairment in those who had suffered a cerebral hemorrhage was significantly greater than among those with cerebral infarction, without significant difference in pain tolerance between different genders and affected sides. ②All of the patients with sensory impairment showed significantly higher CPT and PTT values at the different frequencies, with a positive correlation between them. ③The CPT values of the affected hand and foot at the different frequencies were negatively correlated with muscle strength on the affected side.Conclusions:Both CPT and PTT can usefully represent the degree of sensory disturbance after a stroke. The CPT values of patients with different types of stroke are significantly different, and the degree of sensory disturbance is correlated with the muscle strength of the affected side. Therefore, it is helpful for prognostic judgment and individualized rehabilitation treatment planning by quantifying the degree of sensory disturbance.

Objective To compare the effects of sequential Exoview and Mimics three-dimensional reconstruction with fluorescence method in thoracoscopic pulmonary segmentectomy.Methods The clinical data of 160 patients with lung cancer admitted to our hospital from January 2020 to June 2023 were retrospectively analyzed.Among them,79 patients who underwent thoracoscopic pulmonary segmentectomy with the sequential Exoview three-dimensional reconstruction and fluorescence method before the operation were classified as the Exoview group,and 81 patients who underwent thoracoscopic pulmonary segmentectomy with the sequential Mimics three-dimensional reconstruction and fluorescence method before the operation were classified as the Mimics group.The surgical completion status,the coincidence rate between the number of left and right pulmonary artery branches evaluated before operation and intraoperative findings,reconstruction time,segment display effect,general indicators of operation(operation time,intraoperative blood loss,number of lymph node dissection,thoracic tube placement time,postoperative hospital stay),pulmonary function[forced expiratory volume in one second(FEV1),percentage of forced expiratory volume in one second(FEV1%)]and complications were compared between the two groups.Results All patients in the two groups successfully completed thoracoscopic pulmonary segmentectomy,and indocyanine green was injected once in each group.The operation process was roughly consistent with the preoperative simulation,and no thoracotomy was performed.There was no statistically significant difference in the resection of lung segment between the two groups of patients(P>0.05).The coincidence rate between the number of left and right pulmonary artery branches evaluated before operation and intraoperative findings in the Exoview group was higher than that in the Mimics group(P<0.05).There was no significant difference in the segment display effect between the Exoview group and the Mimics group(P>0.05).The operation time and the reconstruction time in the Exoview group were shorter those that in the Mimics group,and the intraoperative blood loss was less than that in the Mimics group(P<0.05).There was no significant difference in the number of lymph node dissection,the thoracic tube placement time,or the postoperative hospital stay between the two groups(P>0.05).There was no statistically significant difference in FEV1 or FEV1%7 days after surgery compared with those before surgery(P>0.05).The FEV1 and FEV1%of patients in the Mimics group 7 days after surgery were lower than those beforesurgery(P<0.05).There was no statistically significant difference in FEV1 or FEV1%between the Exoview group and the Mimics group before and 7 days after surgery(P>0.05).The total incidence of complications in the Exoview group was 1.27%,compared with 4.94%in the Mimics group,the difference was not statistically significant(P>0.05).Conclusion Both sequential Exoview and Mimics three-dimensional reconstruction with fluorescence method are safe and effective for thoracoscopic pulmonary segmentectomy,while Exoview has more advantages in preoperative assessment of the number of pulmonary artery branches,and it has shorter reconstruction time and operation time,with less impact on lung function.

Objective:To summarize the clinicopathological features, evolving trends in treatment and surgical approaches, and survival outcomes of patients who underwent D2 radical gastrectomy for gastric cancer in Shanxi Provincial Cancer Hospital over the past 11 years with the goal of providing a reference for the clinical practice of gastric cancer in this region.Methods:A retrospective observational study was conducted to analyze the clinicopathological data of patients who underwent D2 radical gastrectomy for pathologically confirmed gastric malignancy at the Department of Gastrointestinal Surgery, Shanxi Provincial Cancer Hospital from January, 2013 to December, 2023. Exclusion criteria consisted of: (1) residual gastric cancer or recurrent gastric cancer after surgery; (2) emergency gastric cancer resection due to bleeding, perforation, obstruction, or other causes; (3) comorbidity with other primary malignant tumors; (4) severe preoperative cardiopulmonary insufficiency or hepatic and renal insufficiency who cannot tolerate radical surgery; and (5) inconsistent main diagnosis information across the medical record system, pathological system, and gastric cancer-specific database. Patients were divided into three groups based on treatment methods: the surgery-only group, the perioperative chemotherapy group, and the adjuvant chemotherapy group. Endpoints included: (1) baseline patient characteristics; (2) trends in tumor location and pathological features; (3) evolution of treatment modalities; and (4) survival outcomes.Results:A total of 15,644 patients were included in the analysis, with 12,591 males and 3,053 females, the male-to-female gender ration was approximately 4∶1; the mean age was (61.2±9.5) years. The tumor sites were mainly concentrated in the esophagogastric junction (EGJ) (57.4%), followed by the antrum (25.9%). The incidence of EGJ cancer initially rose and then declined. However, gastric antrum tumors remained stable, and gastric body tumors showed a slow upward trend after 2020, accounting for 16.7%. In terms of pathological types, poorly differentiated carcinoma was the most prevalent, accounting for 55.9%, followed by moderately differentiated carcinoma (24.2%), mucinous adenocarcinoma (or signet ring cell carcinoma,14.1%), neuroendocrine carcinoma (4.8%), and well-differentiated carcinoma (0.9%). The proportion of poorly differentiated adenocarcinoma showed a significant upward trend overall as well, peaking at 65.6% in 2022 and decreasing to 57.5% in 2023. Mucinous adenocarcinoma (or signet ring cell carcinoma) exhibited fluctuations with a first increase followed by a decrease: it peaked at 17.3% in 2018, dropped sharply to 8.4% in 2022, and rose back to 13.8% in 2023. The proportions of well-differentiated adenocarcinoma, moderately differentiated adenocarcinoma, and neuroendocrine tumors remained stable year by year. In terms of pathological staging, the overall proportions of gastric cancer at Stage 0, Stage I, Stage II, Stage III, and Stage IVa were 0.5%, 17.3%, 25.1%, 54.9%, and 2.3%, respectively. For Stage III, its proportion was 74.6% in 2013, which decreased to 46.4% by 2023. Stages I and II gastric cancer showed an upward trend, with their proportions rising from 10.2% and 12.1% in 2013 to nearly 21.0% and 29.6% in 2023, respectively. Between 2013 and 2023, the proportion of patients who received surgery alone continued to decrease, with this proportion dropping to 34.7% in 2023. In contrast, the number of patients who received adjuvant chemotherapy increased year by year, reaching 54.2% in 2023. Since 2017, the application of perioperative chemotherapy has gradually increased, rising to 11.1% in 2023. Immunotherapy showed an almost synchronous growth trend with perioperative chemotherapy. However, targeted therapy exhibited a downward trend after a period of growth. There were 10,704 cases of open surgery (68.4%), 4,744 cases of laparoscopic surgery (30.3%), and 193 cases of transthoracic surgery (1.2%). Pathological margin positivity was observed in 443 cases (2.8%), and the volume of gastric cancer surgeries gradually increased, peaked in 2021 before subsequently decreasing gradually. However, the volume of laparoscopic surgeries did not decrease; instead, it showed an upward trend. The main resection method for EGJ tumors was total gastrectomy, accounting for 78.5% of the total, followed by proximal gastrectomy, which accounted for 21.5%. After total gastrectomy, esophagojejunal Roux-en-Y anastomosis was the primary anastomotic method, and for proximal gastrectomy, the main anastomotic method was esophagogastric anastomosis, which accounted for 68.0% of the total. For distal gastrectomy, Billroth II anastomosis was the most common anastomotic technique, accounting for 92.7% of these procedures. The overall incidence of postoperative complications was 14.5% (2,264/15,644), among which the incidence of severe complications (grades III-IV) was 4.5% (706/15,644). The entire cohort was followed up with for (47.1±36.8) months, and the 1-year, 3-year, and 5-year overall survival rates were 86.4%, 65.9%, and 58.1%, respectively. For patients with stage 0, I, II, III, and IV gastric adenocarcinoma, the 1-year overall survival rates were 95.7%, 98.0%, 89.4%, 81.0%, and 49.1%, respectively; the 3-year overall survival rates were 92.1%, 94.6%, 81.9%, 51.4%, and 14.7%, respectively; and the 5-year overall survival rates were 89.4%, 91.7%, 75.1%, 41.5%, and 10.0%, respectively. For patients with stage I, II, III, and IV gastric neuroendocrine carcinoma, the 1-year overall survival rates were 96.7%, 91.1%, 73.8%, and 52.6%, respectively; the 3-year overall survival rates were 87.2%, 69.6%, 46.1%, and 32.1%, respectively; and the 5-year overall survival rates were 87.2%, 62.2%, 36.7%, and 32.1%, respectively.Conclusions:Gastric cancer in Shanxi Province is characterized by a male predominance, a high prevalence of tumors at the esophagogastric junction, a large proportion of poorly differentiated adenocarcinoma, and presentation at advanced stages (predominantly Stage III). The detection rate of early gastric cancer has been increasing year by year, the volume of laparoscopic surgeries has been on the rise annually, and the treatment model has shifted from single surgery to comprehensive treatment.
