ObjectiveTo investigate the imaging features of calcium salt deposition and serological markers in patients with alveolar echinococcosis through a retrospective analysis， as well as independent risk factors for the degree of calcium salt deposition in lesions， and to provide a basis for assessing disease process. MethodsA retrospective analysis was performed for the imaging and clinical data of 107 patients with alveolar echinococcosis who were admitted to The First Affiliated Hospital of Shihezi University from December 2023 to June 2025， and according to the volume of calcium salt deposition， they were divided into non-deposition group with 16 patients， mild deposition group with 52 patients， moderate deposition group with 16 patients， and severe deposition group with 23 patients. A one-way analysis of variance or the Kruskal-Wallis H test was used for comparison of continuous data between groups， and the χ² test or Fisher’s exact test was used for comparison of categorical data between groups. The four groups were further combined into the low deposition group （no/mild deposition） and the high deposition group （moderate/severe deposition）. A binary logistic regression analysis was used to investigate the independent influencing factors for calcium salt deposition， and a predictive model was established. The receiver operating characteristic （ROC） curve was used to assess the predictive performance of the model， and the Bootstrap method was used for internal validation. ResultsThere were significant differences between the four groups in sex distribution， involvement of other sites， white blood cell count， lymphocyte percentage， fibrinogen， uric acid， sodium ion， chloride ion， and calcium ion （all P<0.05）. The univariate analysis showed that there were significant differences between the four groups in sex， involvement of other sites， white blood cell count， lymphocyte percentage， fibrinogen， alanine aminotransferase， albumin， creatinine， uric acid， sodium ion， chloride ion， and calcium ion （all P<0.1）. The multi-collinearity diagnosis showed that the VIF values for all continuous variables ranged from 1.104 to 1.760， suggesting that collinearity did not affect modeling. An ordinal logistic regression model was established based on sex， involvement of other sites， calcium ion， lymphocyte percentage， and uric acid. The multivariate analysis showed that lymphocyte percentage （odds ratio ［OR］=1.106， 95% confidence interval ［CI］： 1.041 — 1.174， P=0.001） and blood calcium level （OR=0.005， 95%CI： 0.000 —0.230， P=0.007） were independent influencing factors for the degree of calcium salt deposition. The regression equation was established as Logit（P）=8.231 + 0.100 × lymphocyte percentage -5.344 × calcium ion. The ROC curve analysis showed that the model had an area under the ROC curve of 0.716， with a Youden index of 0.353， a sensitivity of 1.000， and a specificity of 0.353. The Hosmer-Lemeshow test showed that the model had poor calibration （χ²=20.688， P=0.008）. The Bootstrap method with 1000 repeated samples showed that the estimated values of lymphocyte percentage （OR=1.106， 95%CI： 1.049 — 1.186， P=0.002） and calcium ion （OR=0.005， 95%CI： 0.000 — 0.214， P=0.010） were consistent with the original model， and the confidence intervals did not include 1， which further supported the reliability of the model. ConclusionBoth lymphocyte percentage and blood calcium level are independent influencing factors for calcium salt deposition in alveolar echinococcosis， and the degree of calcium salt deposition in alveolar echinococcosis lesions increases with the reduction in blood calcium level and the increase in lymphocyte percentage.

Purpose To explore the diagnostic efficacy of 99Tcm labeled fibroblast activation protein inhibitor(FAPI)SPECT/CT for metastatic lesions in advanced colorectal cancer and its impact on decisions regarding immunotherapy,and to compare it with 18F-FDG PET/CT.Materials and Methods A total of 34 patients with advanced colorectal cancer who underwent both 99Tcm-FAPI SPECT/CT and 18F-FDG PET/CT imaging from August 2022 to November 2023 in Fuzhou University Affiliated Provincial Hospital were prospectively included.The gold standard was based on biopsy or clinical and imaging follow-up results.Chi-square tests and rank sum tests were used to compare differences between the groups.Results Among the 34 patients,17 patients subsequently received immunotherapy.The uptake of 99Tcm-FAPI was significantly higher than that of 18F-FDG for the primary tumor site(Z=-2.389,P=0.017),peritoneal metastasis(Z=-2.497,P=0.013)and liver metastasis(Z=-0.106,P=0.015).The diagnostic efficacy of 99Tcm-FAPI SPECT/CT for patients with peritoneal metastasis was superior to that of 18F-FDG PET/CT(χ2=4.65,P=0.033).Metastatic lesions that did not uptake 99Tcm-FAPI had a better clinical prognosis after immunotherapy(χ2=11.839,P=0.006),and maximum standardized uptake value(SUVmax)-FDG/SUVmax-FAPI ratio was a promising predictive factor for a better prognosis after immunotherapy,with an optimal cut-off value of 5.04.Conclusion 99Tcm-FAPI SPECT/CT has superior diagnostic efficacy for peritoneal metastasis in advanced colorectal cancer compared with 18F-FDG PET/CT.SUVmax-FDG/SUVmax-FAPI ratio is a promising radiomic parameter for predicting patient prognosis after immunotherapy,which can help guide clinical decision-making further.

Objective:This study aimed to explore the utility of transcutaneous electrical acupoint stimulation (TEAS) combined with skin sympathetic response (SSR) in assessing the effectiveness of perigastric autonomic nerve preservation during radical gastrectomy.Methods:A retrospective cohort analysis was conducted involving 221 patients who underwent laparoscopic radical gastrectomy at the Department of Gastric Surgery, Taizhou People's Hospital, affiliated with Nanjing Medical University, between June 2022 and September 2024. The cohort comprised 109 patients who underwent laparoscopic radical total gastrectomy without autonomic nerve preservation (total gastrectomy without nerve preservation group). Additionally, 112 patients underwent laparoscopic radical distal gastrectomy, including 34 patients who received autonomic nerve preservation (nerve preservation group) and 78 patients who did not (without nerve preservation group). TEAS was administered at the Zusanli and Tianshu acupoints one day before and one day after surgery, during which SSR latency and voltage amplitudes in the upper and lower extremities were recorded and compared across groups. Differences in SSR latency and voltage amplitude between the nerve preservation and non-nerve preservation groups of the distal gastrectomy cohort were also analyzed. Further, TEAS was applied at the same acupoints for 15 minutes on the 1st, 2nd, and 3rd postoperative days, and changes in intestinal sounds and intestinal functional recovery time were monitored. Surgical parameters, including operative duration, intraoperative blood loss, and harvested lymph node, were documented. Postoperative inflammatory indicators, including interleukin-6 (IL-6), C-reactive protein (CRP), procalcitonin (PCT), and the incidence of anastomotic leakage, were evaluated. At three months postoperatively, gastroscopy was performed to assess residual gastric food and bile reflux. Additionally, the prognostic nutritional index (PNI) was evaluated across all patient groups.Results:Following total gastrectomy, TEAS of Zusanli combined with arms' SSR revealed a latency of (23 59.71±410.55) ms and a voltage amplitude of (0.43±1.67) mV; for the legs, latency was (2 596.88±369.01) ms and voltage amplitude was (0.25±0.08) mV. TEAS of Tianshu combined with arms' SSR demonstrated a latency of (2 746.47±224.37) ms and a voltage amplitude of (0.31±0.14) mV; for the legs, latency was (2 891.90±193.61) ms and voltage amplitude was (0.19±0.72) mV. Postoperative latency was significantly prolonged, and voltage amplitude was markedly reduced (all P < 0.01). In the distal gastrectomy with nerve preservation group, TEAS of Zusanli combined with arms' SSR showed a latency of (1 668.04±261.91) ms and a voltage amplitude of (0.78±0.26) mV; for the legs, latency was (1 568.86±220.09) ms and voltage amplitude was (0.61±0.24) mV. TEAS of Tianshu combined with arms' SSR demonstrated a latency of (1 519.36±206.99) ms and a voltage amplitude of (0.66±0.34) mV; for the legs, latency was (2 004.80±508.53) ms and voltage amplitude was (0.55±0.28) mV. In the distal gastrectomy without nerve preservation group, TEAS of Zusanli combined with arms' SSR revealed a latency of (2 385.95±710.27) ms and a voltage amplitude of (0.23±0.11) mV; for the legs, latency was (2 506.81±779.37) ms and voltage amplitude was (0.26±1.29) mV. TEAS of Tianshu combined with arms' SSR indicated a latency of (2 697.78±385.55) ms and a voltage amplitude of (0.21±0.14) mV; for the legs, latency was (2 949.14±506.61) ms and voltage amplitude was (0.17±0.11) mV. The group without nerve preservation exhibited significantly prolonged latencies and reduced voltage amplitudes (all P<0.01). No statistically significant differences were observed between the groups in operative time, intraoperative bleeding, the number of dissected lymph nodes, inflammatory indicators (IL-6, CRP, PCT) at 3 days postoperatively, or anastomotic leakage rates (all P>0.05). In the group without nerve preservation, bowel sounds on postoperative days 1, 2, and 3 were (0.36±0.58), (1.04±0.97), and (1.74±1.10) times/min, respectively, with bowel function recovery time of (62.24±9.91) hours. The PNI at 3 months postoperatively was (37.42±3.01). Incidences of food residue in the residual stomach and bile reflux were 21.79% (17/78) and 29.49% (23/78), respectively. In the group with nerve preservation, bowel sounds on postoperative days 1, 2, and 3 were (0.76±0.82), (2.03±1.34), and (3.71±1.27) times/min, respectively, with bowel function recovery time of (44.94±8.05) hours. The PNI at 3 months postoperatively was (41.34±3.40). Incidences of food residue and bile reflux were 5.88% (2/34) and 11.76% (4/34), respectively. Statistically significant differences were observed between the groups (all P < 0.05). Conclusion:TEAS of Zusanli and Tianshu combined with SSR provides an objective measure for assessing the preservation of perigastric autonomic nerves during radical gastrectomy.

Objective:To explore the clinical efficacy of double tract reconstruction and single flap valvuloplasty technique in laparoscopic proximal gastrectomy.Methods:A retrospective cohort study was adopted to analyze the clinical data of 65 patients with gastric cancer who underwent radical proximal gastrectomy at Taizhou People's Hospital Affiliated to Nanjing Medical University from July 2019 to April 2024. According to the different reconstruction methods, the patients were divided into the double tract reconstruction group (double tract; n=43) and oblique anastomosis of esophageal-gastric mucosal window with single flap valvuloplasty technique group (single flap n=22). The baseline data, surgical and postoperative recovery indicators, postoperative pathological results, gastroesophageal reflux at postoperative 6 months, and nutritional status at postoperative 1 year were compared between the two groups. Results:Comparisons of operative time, gastrointestinal reconstruction time, number of lymph nodes dissected, postoperative intestinal function recovery time, total protein, plasma albumin, hemoglobin, and lymphocyte count at 1 week postoperatively, prognostic nutritional index (PNI), time to normalization of postoperative white blood cell count and C-reactive protein, length of hospital stay, hospital costs, and incidence of postoperative pulmonary infection or anastomotic leakage between the two groups showed no statistically significant differences (all P>0.05). However, compared with the double tract group, the single muscle flap group had significantly higher intraoperative blood loss ( P<0.001), higher maximum postoperative body temperature ( P=0.004), and a significantly higher proportion of patients with pleural effusion ≥2 cm ( P=0.029).No statistically significant differences were observed between the two groups in terms of tumor length, length of esophageal involvement, Siewert classification, tumor differentiation degree, neural invasion, lymphovascular invasion, number of metastatic lymph nodes, tumor T stage and N stage, or UICC TNM staging for gastric cancer (all P>0.05). Nevertheless, the minimum distance of the lower resection margin in the double tract group was significantly longer than that in the single muscle flap group, with a statistically significant difference between the groups ( P<0.001). At 6 months postoperatively, results from the Quality of Life Questionnaire-Core 30 (QLQ-C30), Quality of Life Questionnaire-Stomach 22 (QLQ-ST022), Reflux Symptom Index scores, Visick grading, and gastroscopy (Los Angeles classification) all indicated that the incidence of reflux esophagitis in the double tract group was significantly lower than that in the single muscle flap group (all P<0.001). Gastrointestinal contrast examination showed no anastomotic stenosis in either group; gastroesophageal reflux occurred in 5 cases (11.6%) in the double tract group and 4 cases (18.2%) in the single muscle flap group, with no statistically significant difference (χ2=0.524, P=0.469). Gastroscopy results revealed that the incidence of reflux esophagitis at 6 months postoperatively was 9.3% (4/43) in the double tract group and 59.1% (13/22) in the single muscle flap group, with a statistically significant difference between the two groups (χ2=18.680, P<0.001).At 1 year postoperatively, the dual-chamber group showed better performance in body mass index(BMI), proportion of a decrease in BMI, plasma albumin, and PNI compared with the single muscle flap group, with statistically significant differences (all P<0.05). There were no statistically significant differences in hemoglobin or lymphocyte count between the two groups (all P>0.05). During 1 year of follow-up, one case of anastomotic recurrence occurred in each group, with no statistically significant difference between the groups ( P=0.624). Conclusions:Both proximal gastrectomy with double-tract anastomosis and esophagogastric mucosal window oblique anastomosis combined with single muscular flap valvuloplasty for digestive tract reconstruction are safe and feasible. However, double-tract anastomosis can better prevent the occurrence of postoperative reflux esophagitis, improve the patient's postoperative nutritional status, and enhance the patient's quality of life.

Depression is a common mental disorder in clinical practice， and it falls under the category of depression syndrome in traditional Chinese medicine （TCM）. In TCM， Qi depression is considered as the root cause of all depression syndromes. Qi depression can lead to blood stasis， which is a key cause of diseases due to depression syndrome. Therefore， treating stasis is an important therapeutic approach for depression syndrome. Salviae Miltiorrhizae Radix et Rhizoma， a representative herbal medicine for activating blood and removing stasis， is effective in activating blood， removing stasis， dredging meridians， and alleviating pain. Currently， it is primarily used in clinical practice to treat cardiovascular and cerebrovascular diseases， such as neurasthenia， coronary heart disease， insomnia， and palpitations. The active components of Salviae Miltiorrhizae Radix et Rhizoma are complex and exhibit a variety of pharmacological effects. These components include water-soluble salvianolic acids and lipid-soluble tanshinones. Modern pharmacological studies have proven that Salviae Miltiorrhizae Radix et Rhizoma and its active components possess antioxidant， anti-inflammatory， anti-tumor， anti-fibrosis， and neuroprotective properties. In recent years， increasing attention has been paid to the pharmacological effects and mechanisms of Salviae Miltiorrhizae Radix et Rhizoma and its active components in treating depression. This paper systematically reviews the antidepressant mechanisms of Salviae Miltiorrhizae Radix et Rhizoma and its main active components from the regulation of monoamine neurotransmitters， the hypothalamic-pituitary-adrenal axis， neurotrophic factors， and neuroinflammation. In addition， this paper summarizes the clinical applications of the prescriptions containing Salviae Miltiorrhizae Radix et Rhizoma in the treatment of depression， providing new insights for further research on the pharmacological mechanisms of Salviae Miltiorrhizae Radix et Rhizoma in treating depression.

Objective To compare the success rate and stability of rat models of comorbid chronic pain and depression induced by different doses of complete Freund's adjuvant(CFA).Methods Sixty SD rats were divided randomly into a control group,low-dose CFA group(CFA-L),and high-dose CFA group(CFA-H)(n=20 rats per group).Rats in the CFA-L and CFA-H groups were injected with 50 and 100 μL CFA,respectively,and rats in the control group were injected with 0.9％sodium chloride solution.The general state,body weight,mechanical withdrawal threshold(MWT),and thermal withdrawal latency(TWL)were observed at 0,7,14,21,and 28 days after modeling.Depressive behavior was evaluated using the open field test(OFT),forced swim test(FST),and tail suspension test(TST).Glutamate(Glu)and γ-aminobutyric acid(GABA)levels in the anterior cingulate cortex were detected by enzyme-linked immunosorbent assay.Brain-derived neurotrophic factor(BDNF)expression in the anterior cingulate cortex was detected by immunohistochemistry,and pathological changes in the anterior cingulate cortex were observed by HE staining.Results(1)Regarding the general condition of the rats,the left ankle joint and toes were obviously red and swollen in the CFA-L and CFA-H groups on the 7th day after modeling,and the swelling was more severe in the CFA-H group.The redness and swelling of the left hind foot and ankle joint and toes gradually recovered in the CFA-L group on days 14,21,and 28 after modeling,but were still obvious in the CFA-H group,and the water and food intake decreased.(2)The body mass was significantly lower in rats in the CFA-H group compared with those in the blank and CFA-L groups on days 14,21,and 28 after modeling(P＜0.05,P＜0.05).(3)Regarding pain-related behavior,the MWT and TWL were significantly decreased in the CFA-L and CFA-H groups on the 7th and 14th days after modeling,compared with the control group(P＜0.05,P＜0.05).On day 21 after modeling,MWT was significantly lower in the CFA-H group than in the blank and CFA-L groups(P＜0.05,P＜0.05),and TWL was significantly lower in the CFA-L and CFA-H groups than in the blank group(P＜0.05,P＜0.05).On day 28 after modeling,MWT and TWL were significantly lower in the CFA-H group than in the blank and CFA-L groups(P＜0.05,P＜0.05).(4)In terms of depression-related behaviors,the total OFT movement distance was significantly lower in the CFA-H group than in the blank and CFA-L groups on day 7 after modeling(P＜0.05,P＜0.05).The total OFT distance and central dwell time were significantly lower in the CFA-H group than in the blank and CFA-L groups on days 14,21,and 28 after modeling(P＜0.05,P＜0.05),and the result in the FST and TST were significantly higher than in the blank and CFA-L groups(P＜0.05,P＜0.05).(5)Glu,GABA,and BDNF expression levels were significantly higher in the CFA-H group than in the blank and CFA-L groups(P＜0.05,P＜0.05),while GABA,Glu/GABA,and BDNF levels were significantly lower in the CFA-H group than in the blank and CFA-L groups(P＜0.05,P＜0.05,P＜0.05).(6)The CFA-L group showed less damage in the anterior cingulate cortex,more pyramidal cells,more arranged cells,clear nucleoli,and a small number of cells with karyokynesis and deep staining.Compared with the CFA-L group,rats in the CFA-H group showed a disordered cell arrangement in the injured area of the anterior cingulate cortex,a large number of pyknotic and hyperchromatic neurons,significantly fewer or absent pyramidal cells,and vacuoles,red blood cells,and neurofibrillary tangles in the interstitial space.Conclusions Injection of CFA 100 μL can be used to establish a rat model of chronic inflammatory pain and depression,showing hyperalgesia,depression-like behavioral changes,changes in levels of Glu,GABA,and BDNF in the anterior cingulate cortex,and pathological changes in the anterior cingulate cortex,consistent with the pathophysiological characteristics of chronic pain and depression.

Genetic factors are often involved in the pathogenesis of young adult stroke, and its subtype, atherosclerotic type of large arteries, may be caused by a combination of genetic and environmental factors, but little is known about its underlying pathogenesis. To provide clues for better understanding of identifying relevant stroke etiological genetic factors and adopting effective preventive strategies, the role of genetic factors in atherosclerosis and related risk factors was described, and the possible genetic mechanisms of large-artery atherosclerotic stroke in young people were explored, which may be further investigated in future research in the following areas: etiological typing of stroke in young people and the related genetic mechanisms; modifiable vascular risk factors and the development of secondary prevention strategies; high-resolution vascular imaging magnetic resonance imaging in the etiological typing of stroke in young people and the pathogenesis of premature atherosclerosis and vulnerable plaques.

Objective To compare the success rate and stability of rat models of comorbid chronic pain and depression induced by different doses of complete Freund's adjuvant(CFA).Methods Sixty SD rats were divided randomly into a control group,low-dose CFA group(CFA-L),and high-dose CFA group(CFA-H)(n=20 rats per group).Rats in the CFA-L and CFA-H groups were injected with 50 and 100 μL CFA,respectively,and rats in the control group were injected with 0.9％sodium chloride solution.The general state,body weight,mechanical withdrawal threshold(MWT),and thermal withdrawal latency(TWL)were observed at 0,7,14,21,and 28 days after modeling.Depressive behavior was evaluated using the open field test(OFT),forced swim test(FST),and tail suspension test(TST).Glutamate(Glu)and γ-aminobutyric acid(GABA)levels in the anterior cingulate cortex were detected by enzyme-linked immunosorbent assay.Brain-derived neurotrophic factor(BDNF)expression in the anterior cingulate cortex was detected by immunohistochemistry,and pathological changes in the anterior cingulate cortex were observed by HE staining.Results(1)Regarding the general condition of the rats,the left ankle joint and toes were obviously red and swollen in the CFA-L and CFA-H groups on the 7th day after modeling,and the swelling was more severe in the CFA-H group.The redness and swelling of the left hind foot and ankle joint and toes gradually recovered in the CFA-L group on days 14,21,and 28 after modeling,but were still obvious in the CFA-H group,and the water and food intake decreased.(2)The body mass was significantly lower in rats in the CFA-H group compared with those in the blank and CFA-L groups on days 14,21,and 28 after modeling(P＜0.05,P＜0.05).(3)Regarding pain-related behavior,the MWT and TWL were significantly decreased in the CFA-L and CFA-H groups on the 7th and 14th days after modeling,compared with the control group(P＜0.05,P＜0.05).On day 21 after modeling,MWT was significantly lower in the CFA-H group than in the blank and CFA-L groups(P＜0.05,P＜0.05),and TWL was significantly lower in the CFA-L and CFA-H groups than in the blank group(P＜0.05,P＜0.05).On day 28 after modeling,MWT and TWL were significantly lower in the CFA-H group than in the blank and CFA-L groups(P＜0.05,P＜0.05).(4)In terms of depression-related behaviors,the total OFT movement distance was significantly lower in the CFA-H group than in the blank and CFA-L groups on day 7 after modeling(P＜0.05,P＜0.05).The total OFT distance and central dwell time were significantly lower in the CFA-H group than in the blank and CFA-L groups on days 14,21,and 28 after modeling(P＜0.05,P＜0.05),and the result in the FST and TST were significantly higher than in the blank and CFA-L groups(P＜0.05,P＜0.05).(5)Glu,GABA,and BDNF expression levels were significantly higher in the CFA-H group than in the blank and CFA-L groups(P＜0.05,P＜0.05),while GABA,Glu/GABA,and BDNF levels were significantly lower in the CFA-H group than in the blank and CFA-L groups(P＜0.05,P＜0.05,P＜0.05).(6)The CFA-L group showed less damage in the anterior cingulate cortex,more pyramidal cells,more arranged cells,clear nucleoli,and a small number of cells with karyokynesis and deep staining.Compared with the CFA-L group,rats in the CFA-H group showed a disordered cell arrangement in the injured area of the anterior cingulate cortex,a large number of pyknotic and hyperchromatic neurons,significantly fewer or absent pyramidal cells,and vacuoles,red blood cells,and neurofibrillary tangles in the interstitial space.Conclusions Injection of CFA 100 μL can be used to establish a rat model of chronic inflammatory pain and depression,showing hyperalgesia,depression-like behavioral changes,changes in levels of Glu,GABA,and BDNF in the anterior cingulate cortex,and pathological changes in the anterior cingulate cortex,consistent with the pathophysiological characteristics of chronic pain and depression.
