Objective To investigate the effect of different function of sympathetic nerve on the pain of peripheral nerve chronic compression. Methods Forty-eight male Sprague-Dawley rats were made into lower trunk chronic compression models and divided into 6 groups (A1,B1,C1,A2,B2,C2) with 8 rats per group. The C8T1 dorsal root ganglions of the compressed sides of group A1 (control group), B1 (sympathetic block group)and C1 (de-sympathetic group) were harvested 3 months after compression surgery. The compressed lower trunks of group A2 (control group), B2(sympathetic block group)and C2(de-sympathetic group)were decompressed 3 months after compression surgery and bred for another month and then the C8T1 dorsal root ganglions of the compressed sides were harvested. The levels of substance P mRNA in the C8T1 dorsal root ganglions were tested with RT-PCR technique. Results the mean relative levels of substance P mRNA of group A1, B1 and C1 were (3.620 ± 0.830) × 10-2, (2.945 ± 0.724) × 10-2, (2.239 ± 0.734) × 10-2, respectively, with a significant difference (P = 0.006) and those of group A2, B2 and C2 were (3.163 ± 1.026) × 10-2, (2.355 ± 0.680) × 10-2,(1.487 ± 0.802) × 10-2, the difference among which was statistically significant (P = 0.003). Conclusion The pain of peripheral nerve chronic compression is affected by sympathetic function. The more lower the sympathetic function is, the more light the pain is. Sympathetic blockage or resection helps to relieve the pain of peripheral nerve compression disease after being decompressed.

To investigate chemical constituents contained in Skimmia arborescens. The chemical constituents were separated by silica gel column chromatography, pharmadex LH-20, RP-C18, and 1H, 13C-NMR spectroscopic analysis were employed for the structural elucidation. Six coumarin compounds were separated from S. arborescens. Their structures were elucidated as umbelliferone (1), scopoletin (2), scopolin (3), nodakenetin (4), skimmin (5), 6, 7-dimethoxycoumarin (6), and all compounds were separated from the plant for the first time. Using the model of ear swelling caused by xylol of mice, the anti-inflammatory effect of its total extract was evaluated. The result indicated that middle and high dose groups of its total extract could obviously inhibit the ear swelling caused by xylol of mice.

Objective To evaluate the role of surgical resection on synchronous multiple pulmonary nodules identified difficultly in clinics. Methods The clinical data of 97 patients with synchronous multiple pulmonary nodules who received surgical resection between 2012 and 2019 in Hunan Cancer Hospital were retrospectively analyzed. There were 72 males and 25 females, aged 58.1卤9.0 years. Among these patients, there were 78 patients with ipsilateral and 19 patients with bilateral pulmonary nodules. Clinicopathological parameters between main nodules and secondary nodules were evaluated. Perioperative morbidity was also assessed. Results The operation was successfully completed on all patients for the ipsilateral and bilateral lesions. Totally, 71.1% of mian lesions was mostly removed by lobectomy, and the completion rate of video-assisted thoracoscopic surgery (VATS) was 69.1% (67/97); 80.4% of secondary lesions were mostly removed by wedge resection, and the completion rate of VATS was 71.1% (69/97). The incidence of grade 3 or higher complications after unilateral or bilateral surgery was 12.8% and 5.3%, respectively. Postoperative pathology confirmed that the main lesions were malignant in 65 patients (67.0%), mainly adenocarcinoma (63.1%), of which 43.1%were in the stage Ⅰ; 32 patients were benign, mainly tuberculoma (56.3%). There were 29 patients of malignant secondary lesions, 67 benign, and 1 both benign and malignant; the pathological agreement rate of primary and secondary lesions was 54.6% (lung cancer metastases in the lung and all the benign). When the primary lesion was malignant with its diameters of <3 cm, 3-<5 cm, 5-7 cm, >7 cm, the metastatic rate of secondary lesions was 42.5%, 15.8%, 20.0%, 0, respectively. When the primary lesion was malignant with lymph node metastasis, the probability of the secondary lesion being a metastatic tumor was higher than that without lymph node metastasis (46.7% vs. 30.0%, P>0.05). When the primary lesion was malignant and the primary and secondary lesions were located in the same lobe, the secondary lesions were more likely to metastasize (54.5%), while when they were located on different lobes on the same side or different sides, the secondary lesions were more likely to be benign (58.1%, 72.7%), and the possibility of metastasis was small ( 32.6%, 9.1%). When the primary lesion was benign and clinical differential diagnosis was difficult, the secondary lesion was benign. Conclusion For synchronous multiple pulmonary nodules, the diameter of the primary lesion is large, the metastatic rate of secondary lesions tends to decrease. In ipsilateral synchronous multiple pulmonary nodules, especially with node metastasis, the risk of metastatic nodule increases. Bilateral surgical resection does not significantly increase the perioperative morbidity.

ObjectiveTo evaluate the lipid-lowering activity of Quansanqi tablets(QSQ), an innovative new drug of Panax notoginseng. MethodMice and golden hamsters were used to establish a hyperlipidemia model by injecting egg yolk milk and feeding high-fat diets. The levels of total cholesterol (TC),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were detected, and liver function indicators [alanine aminotransferase (ALT), aspartate amino-transferase (AST), and alkaline phosphatase (ALP)] of golden hamsters were detected. Hematoxylin-eosin (HE) staining was used to observe the degree of liver injury. In the experiments, a normal group, a model group, an atorvastatin calcium group, and low-, medium-, and high-dose QSQ groups (0.32, 0.64, 1.28 g·kg-1 for mice, and 0.16, 0.32, 0.64 g·kg-1 for golden hamsters) were set up. ResultCompared with the normal group, the acute hyperlipidemia model mice showed increased TC, TG, and LDL-C levels (P<0.01), and the hyperlipidemia model mice showed increased TC and LDL-C levels (P<0.01). Additionally, the hyperlipidemia model golden hamsters showed increased serum TC, TG, LDL-C, ALT, AST, and ALP levels (P<0.05, P<0.01). HE staining indicated the presence of fat accumulation in the liver, accompanied by inflammatory reactions. Compared with the model group, QSQ of various doses could reduce TC, TG, and LDL-C levels in acute hyperlipidemia model mice (P<0.05, P<0.01), and the high-dose QSQ could reduce TC and LDL-C levels (P<0.01) and increase HDL-C level (P<0.05) in hyperlipidemia model mice, as well as reduce TC, TG, and LDL-C levels in hyperlipidemia model golden hamsters (P<0.05, P<0.01), especially in the first two weeks. In addition, atorvastatin calcium could further increase ALT, AST, and ALP levels (P<0.05, P<0.01) and aggravate liver function damage, while low-dose QSQ could reduce ALT, AST, and ALP (P<0.05), and medium- and high-dose QSQ did not cause further liver function damage. ConclusionQSQ have a significant lipid-lowering effect on different hyperlipidemia model animals and can improve liver function and liver injury.
