Objective To analyze the effect of guizhi gancao decoction on dardiac function and serum VCAM-1 and sE-selectin levels in patients with coronary heart diseaser. Methods Fifty-eight patients with coronary heart disease were enrolled in this study from September 2014 to June 2015. According to the different treatment methods, 40 patients were treated with conventional western medicine. The observation group of 40 cases were treated with conventional western medicine and Guizhi licorice soup. The effects of cardiac function, 6-minute walking test, cardiac parameters and serum sE-Selectin and ICAM-1 levels were observed. Results Observation group of patients with cardiac ultrasound parameters LVEF (43.27 ± 5.21)%, LVEDd (59.34 ± 5.43) mm, FS (26.32 ± 1.63)%, E / A (1.23 ± 0.22) and 6 min walking distance were better than those of the control group (t=2.3628,P =0.0206;t=2.4643,P=0.0159;t=2.7831,P =0.0068;t=2.5023,P =0.0144;t=3.7571,P =0.0006). The markedly effective rate was 47.50%, which was higher than that of the control group (25.00%), and there was significant difference (χ2 = 4.3813, P= 0.0363). In the observation group, 4 patients were ineffective and the inefficiency rate was 10.00%, which was significantly lower than that of the control group (χ2 = 4.0205,P= 0.0450). The levels of TC (5.21 ± 0.82) mmol / L, TG (1.22 ± 0.32) mmol / L and LDL-C (2.44 ± 0.52) mmol / L were significantly lower in the observation group than those in the control group (t= 3.2729, P = 0.0016; t= 3.5119, P = 0.0007; t= 3.5136, P= 0.0007). While the HDL-C (1.21 ± 0.17) mmol / L index was higher than that of the control group (t = 5.4575, P = 0.0000). There was no significant difference in serum index between the two groups before treatment . After treatment, the serum sE-Selectin (75.58 ± 9.97) ng / mL and VCAM-1 (662.43 ± 65.78) ng / mL were lower than those in the control group (t = 3.4082, P = 0.0010;t = 3.3088, P = 0.0014). Conclusion Treatment of CHF patients with CRT / CRT-D pacemaker implantation in the heart after surgery can effectively improve its clinical condition, and the effect is outstanding, side effects, and CRT-D better effect.

Objective To evaluate the effectiveness and influencing factors of 131I treatment for cervical lymph node metastases of papillary thyroid carcinoma (PTC).Methods Eighty-nine post-operative PTC patients (24 males,65 females,11-72 years) with cervical lymph nodes as the only site of metastasis (negative serum TgAb,1-4 times of 131I treatment) on 131I planar Rx-WBS or SPECT/CT were retrospectively reviewed.Results of 131I Rx-WBS or SPECT/CT,serum Tg levels under both TSH-suppressed and TSH-stimulated conditions were measured and recorded.CR and PR were recognized as effective therapy.x2 test and logistic regression analysis were used to analyze the data.Results The effective rate of 1-4 times of 131I treatment was 57.30％(51/89),73.03％(65/89),80.90％(72/89),83.15％(74/89),respectively (x2=18.792,P＜0.01).Logistic regression analysis suggested that therapeutic effectiveness was related to the size of metastatic lymph nodes and whether metastatic lymph nodes could be visualized on the post-ablative 131I Rx-WBS or SPECT/CT.Conclusions 131I treatment is an effective modality for PTC patients with cervical lymph nodes as the only site of metastasis.The cumulative effective rate increased within a limited times of treatment.The size of metastatic lymph nodes and whether metastatic lymph nodes could be visualized on the first post-ablative 131I Rx-WBS or SPECT/CT are the key factors for the therapeutic effectiveness.

Objective:To investigate the clinicopathological characteristics and 18F-fluorodeoxyglucose (FDG) PET/CT imaging features of bronchopulmonary neuroendocrine tumors(BP-NETs) with different pathological subtypes. Methods:From January 2013 to May 2018, 280 patients (196 males, 84 females, median age 58 years) with BP-NETs proved by pathology in Henan Provincial People′s Hospital were retrospectively analyzed. Age, gender, smoking history, the location and size of tumor, Ki-67 positive index, thyroid transcription factor-1 (TTF-1), synaptophysin (Syn), chromogranin-A (CgA), CD56, maximum standardized uptake value (SUV max), lymph node metastasis and distant metastasis were compared among 4 pathological subtypes of BP-NETs, including typical carcinoid (TC), atypical carcinoid (AC), small cell lung carcinoma (SCLC) and large cell neuroendocrine carcinoma (LCNEC). One-way analysis of variance, χ2 test, Fisher exact test and Kruskal-Wallis rank sum test were used for data analysis. Results:There were significant differences in age, smoking history, tumor size and location, Ki-67 positive index, CgA, CD56, TTF-1, SUV max and TNM stage among TC( n=59), AC( n=21), SCLC( n=184) and LCNEC ( n=16) groups ( F values: 2.067, 3.358, H values: 17.749-22.351, all P<0.05). SCLC had the largest tumor size (5.5(3.0, 6.8) cm) and the highest proportion of central type (85.3%, 157/184), and were more prone to lymph node metastasis. LCNEC had the oldest age ((66±16) years), the largest proportion of smoking history (14/16) and peripheral type (12/16). CD56 in SCLC (95.7%, 176/184) and LCNEC(15/16) mostly showed positive expression, while the positive expression rates of CgA and TTF-1 were higher in TC and AC (96.6%(57/59), 93.2%(55/59) and 95.2%(20/21), 90.5%(19/21), respectively). The Ki-67 positive index and SUV max of the four subtypes were significantly different, with the highest in SCLC group and the lowest in TC group. Conclusion:Different pathological subtypes of BP-NETs manifest different clinicopathological features and imaging presentation on 18F-FDG PET/CT, which are useful for understanding their characteristics.

Objective:To investigate the effect of lateral tibial periosteum distraction on diabetic foot and vasculitis foot.Methods:A retrospective analysis of 13 patients (16 feet) who received lateral tibial periosteal distraction between June 2019 and May 2020 were included in the study. 9 males and 4 females; aged 39-77 years (average 66 years); left foot 7 cases, right foot 9 cases. 5 cases were patients with diabetic foot, 1 case was diabetic foot with arteriosclerosis obliterans, 2 cases were thromboembolic vasculitis, and 5 cases were arteriosclerosis obliterans. The tibial periosteum was dissected and a distraction device was placed. In the 3 patients with foot ulcers, tibial periosteum distraction devices were placed on the severer side. The periosteal distraction began on the third day after surgery, about 0.75 mm/d, the adjustment was done usually in two weeks. Two weeks later, the stretch plate was removed surgically. The followings were evaluated: visual analogue scale (VAS) pain score, foot peripheral oxygen saturation, foot capillary filling test, lower extremity arterial CT angiography (CTA), etc.Results:All 13 patients were followed up for 2-12 weeks, with an average of 3.85 weeks. VAS pain score: the average pain score of 13 patients with preoperative foot pain was 5.31±1.84 (range, 2-9) points, and 2 weeks after surgery, the average value was 2.46±1.39 (range, 1-6) points with statistical significance ( t=6.124, P<0.001) ; peripheral foot oxygen saturation: the average preoperative blood oxygen saturation of 12 patients was 87.83%±14.83% (range, 50%-98%), 1 patient was not detected before surgery, and 2 weeks after operation, the average blood oxygen saturation was 92.33%±7.91% (range, 75%-99%). There was no significant difference between them ( t=1.124, P=0.285). The foot skin temperature of 10 patients was 35.68±0.85 ℃ (range, 34.00-36.60 ℃) before surgery and 36.23±0.46 ℃ (range, 35.50-36.90 ℃) after surgery, and the difference was statistically significant ( t=3.197, P=0.008) . Capillary filling test: 2 weeks after operation, the capillary filling response was significantly improved. All 13 patients had improved CTA of both lower extremity arteries before operation, and 11 patients had CTA taken back after two weeks of operation. Compared with preoperative CTA, new vascular network was found in the operation limb. In addition to 1 patient with thromboangiitis obliterans (mainly suffering from foot pain, no wound symptoms), 2 of 12 patients with heart failure, renal failure and other basic diseases did not heal, and the wounds of the other 10 patients had improved significantly 1 month later. Conclusion:Lateral tibia periosteum distraction can be used to treat chronic ischemic diseases of lower extremities with satisfactory postoperative results.

Objective:To explore the clinical value of semi-ex vivo intestinal autotrans-plantation (IATx) for patients with mesenteric root regional tumors accompanied by vascular invasion.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 6 patients who underwent semi-ex vivo IATx in the Sichuan Academy of Medical Sciences & Sichuan Provincial People's Hospital from September 2021 to December 2022 were collected. There were 4 males and 2 females, aged (47±21)years. Observation indicators: (1) surgical conditions; (2) postoperative conditions; (3) follow-up. Measurement data with normal distribution were represented by Mean± SD. Count data were represented by absolute numbers. Results:(1) Surgical conditions. All 6 patients completed semi-ex vivo IATx successfully. The operation time, warm ischemia time, cold ischemia time, volume of intraoperative blood transfusion were (10.2±2.1)hours, (2.3±1.6)minutes, (49.2±15.6)minutes, (707±263)mL. Of the 6 patients, 3 patients were intraoperatively perfused with cold UW solution, while the other 3 were not. (2) Postoperative conditions. Results of postoperative pathological examination of the 6 patients showed 4 cases of pancreatic ductal adenocarcinoma, 1 case of cholangiocarcinoma, and 1 case of mesenteric fibromatosis. All 6 cases had nega-tive surgical margins and the duration of postoperative hospital stay was (19±4)days. None of the patient had gastrointestinal bleeding or anastomotic leakage postoperatively, and the autotransplanted intestine functioned well. There was no perioperative death, and intravenous rehydration was not required after discharge. (3) Follow-up. All 6 patients were followed up for (12±5)months. Only 1 patient with mesenteric fibromatosis had recurrence in the 7th month postoperatively, while the remaining 5 patients showed no sign of recurrence or metastasis. There were 4 of 6 patients with chronic diarrhea. They were improved after oral loperamide, bifidobacterium and pancreatin capsules. All 6 patients survived.Conclusion:Semi-ex vivo IATx for the treatment of patients with mesenteric root regional tumors accompanied by vascular invasion is safe and feasible, which can achieve good short-term efficacy.

Objective:To study the correlation between changes of cerebral striatal dopamine D 2 receptors non-displaceable binding potential (BP ND), functional connectivity (FC) and clinical symptoms in patients with first-episode major depressive disorder (MDD), by 11C-Raclopride PET/CT and resting state fMRI (rs-fMRI). Methods:Thirty-eight first-episode depression patients (MDD group) and forty healthy volunteers (control group) matched with age, gender and years of education were selected. All subjects were scored with Hamilton depression scale (24 versions) before enrollment.All the subjects underwent cerebral 11C-Raclopride PET/CT and rs-fMRI in resting state. MIAKAT and DPARSF were used to analyze BP ND of cerebral striatal dopamine D 2 receptors and FC of striatum and the whole brain in subjects, respectively. Changes of striatal dopamine D 2 receptors BP ND and striatum and the whole brain FC of MDD were analyzed, and correlations among BP ND, FC and Hamilton depression rating scale were calculated by Rest 1.8 and SPSS 20.0. Results:Compared with the control group, BP ND of bilateral caudate nucleus and putamen dopamine D 2 receptors in the MDD group were decreased(left caudate nucleus: 1.16±0.37 vs 1.48±0.39, right caudate nucleus: 1.21±0.31 vs 1.62±0.48, left putamen: 1.73±0.47 vs 2.21±0.66, right putamen: 1.79±0.46 vs 2.17±0.65, t=3.66, -4.42, -3.68, -2.91, all P<0.001). Besides, FC of left caudate nucleus and left medial prefrontal lobes(4.38±1.31, 2.35±0.48), left caudate nucleus and left middle frontal gyrus(3.36±1.11, 1.64±0.56), left caudate nucleus and left superior frontal gyrus(3.14±0.78, 1.64±0.53), left putamen and left medial prefrontal lobes(4.10±1.42, 2.42±0.64, t=6.82, P<0.05), right caudate nucleus and right medial prefrontal lobes (4.32±1.30, 2.33±0.63, t=8.51, P<0.05), right putamen and right medial prefrontal lobes(3.77±1.25, 2.31±0.63, t=6.49, P<0.05)in the MDD group were increased.FC of left putamen and left anterior cingulate(1.60±0.55, 2.68±0.84, t=-6.76, P<0.05), right caudate nucleus and right amygdala (1.67±0.57, 3.46±0.64, t=-8.27, P<0.05) in the MDD group were decreased. Furthermore, there were significant negative correlations between D 2 receptors BP ND of bilateral striatum and FC of the same lateral striatum and medial prefrontal lobes ( r=-0.66, -0.50, -0.67, -0.47, all P<0.05). In MDD group, FC in left caudate nucleus and left medial prefrontal lobe were positively correlated with total score of Hamilton depression scale and anxiety somatization( r=0.55, 0.68, P<0.001). FC in left putamen and left medial prefrontal cortex were positively correlated with cognitive impairment and retardation ( r=0.37, 0.40, P=0.021, 0.001). FC of right caudate nucleus and right medial prefrontal lobe were positively correlated with Hamilton depression scale total score and anxiety somatization ( r=0.52, 0.67, all P<0.001). FC in right putamen and right medial prefrontal cortex was positively correlated with cognitive impairment ( r=0.50, P=0.002). Conclusion:The abnormal BP ND of cerebral striatal dopamine D 2 receptor of patients with first-episode depression is related to the abnormal activity of dopamine reward circuit related neurons in patients with MDD, which was related to clinical symptoms of depression. It may be involved in the pathogenesis of depression.

【Objective】 To analyze the correlation between CT attenuation value of renal papilla and occurrence and development of renal calculi. 【Methods】 The clinical data of 100 patients with calcium oxalate stones treated during Aug.2020 and Jul.2022 were retrospectively analyzed, including 60 with primary stones, and 40 with recurrent stones. The 30 healthy volunteers were enrolled in the control group. CT attenuation value of renal papilla was measured with plain scan CT, and risk factors were identified with the receiver operating characteristic (ROC) curve. The correlation of CT attenuation value and 24 h urine metabolism was analyzed. 【Results】 The CT attenuation value of renal papilla was significantly higher in the primary group [34.92 (IQR: 3.84)] and recurrent group [43.00 (IQR: 8.74)] than in the control group [32.58 (IQR: 5.21)] (P<0.05). Compared with the primary group, the recurrent group had decreased citric acid level but increased calcium level in 24 h urine (P<0.05). The citrate ion and calcium ion were correlated with the CT attenuation value (P<0.05). 【Conclusion】 Patients with high renal papilla density have a high risk of stone formation and recurrence. Increased renal papilla density is a warning signal for the development of stones. The high calcium and low citric acid in 24 h urine have certain effects on the occurrence and development of urolithiasis. Intake of calcium should be limited and citric acid should be supplemented in patients with calcium oxalate stones.

Ischemic stroke (IS) is a severe cerebrovascular disease with a high incidence, mortality, and disability rate. The first-line treatment for IS is the use of recombinant tissue plasminogen activator (r-tPA). Regrettably, numerous patients encounter delays in treatment due to the narrow therapeutic window and the associated risk of hemorrhage. Traditional Chinese medicine (TCM) has exhibited distinct advantages in preventing and treating IS. TCM enhances cerebral microcirculation, alleviates neurological disorders, regulates energy metabolism, mitigates inflammation, reduces oxidative stress injuries, and inhibits apoptosis, thereby mitigating brain damage and preventing IS recurrence. This article summarizes the etiology, pathogenesis, therapeutic strategies, and relationship with modern biology of IS from the perspective of TCM, describes the advantages of TCM in the treatment of IS, and further reviews the pharmacodynamic characteristics and advantages of TCM in the acute and recovery phases of IS as well as in post-stroke complications. Additionally, it offers valuable insights and references for the clinical application of TCM in IS prevention and treatment, as well as for the development of novel drugs.
