OBJECTIVETo explore the effects of sacral canal injection on nerve root local inflammatory factors in rat model with lumbar disc herniation, in order to identify its mechanism of treatment.

METHODSForty-eight male SD rats were randomly divided into sham operation group(group A), model group (group B), Chinese medicine group(group C) and western medicine group(group D). There were 12 rats in each group. The model of lumbar disc herniation was established using compression and inflammatory stimulation in group B, C, D. All rats were given epidural catheterization and group A and B with physiological saline (1 ml/kg), group C with mixed liquor of 2% lidocaine and compound Danshen injections and physiological saline (2:2: 16) and group D with mixed liquor of 2% lidocaine and triamcinolone acetonide injection and physiological saline (2:2:16), once a week for a total of three treatments. Four rats were killed every 1 week after injection for once, and the inflammatory factors of tumor necrosis factor (TNF-alpha), prostaglandin E2 (PGE2), interleukin-l (IL-1) and interleukin-6 (IL-6) were detected by ELISA method.

RESULTSThe levels of TNF-alpha, PGE2, IL-1 and IL-6 in compressed nerve tissues in group B were increased than those of group A (P < 0.01). The levels of PGE2, IL-1 and IL-6 in group C and D were decreased than those of group B, and group D was much less(P<0.05). There was no significant difference in level of TNF-alpha among group B, C, D (P > 0.05).

CONCLUSIONCompound compression with inflammatory stimulation can lead to massive release of inflammatory mediators, such as TNF-alpha, PGE2, IL-1 and IL-6. Both injection with compound Danshen injections and triamcinolone acetonide injections by sacral canal can reduce the levels of part inflammatory mediators (PGE2, IL-1 and IL-6), and the effect of Glucocorticoid is better than Danshen (P < 0.05).

Plasma ghrelin level was measured by RIA in 49 grids with idiopathic central precocious puberty(ICPP)and 35 girls with simple premature thelarche(PT).The results showed that the plasma ghrelin level was negatively correlated with Tanner stage,bone age,Lid at 15,30 and 60 min after GnRH activation, uterus and ovary volumes.The plasma ghrelin level in the ICPP group was remarkably lower than that in the PT and control groups(both P

This study aimed to investigate the mechanism of "Trichosanthis Fructus-Allii Macrostemonis Bulbus" (GX) on phlegm and blood stasis syndrome (PBSS) rats combining the methods of network pharmacology and experimental verification. Animal experiment ethical requirements were approved by the Ethical Committee Experimental Animal Center of Anhui University of Chinese Medicine (grant number: AHUCM-rats-2021070). Based on the HPLC-Q-TOF-MS analysis and database, 69 chemical constituents of GX and 163 targets of GX for the treatment of phlegm and blood stasis-related cardiovascular diseases were obtained. Then, key targets such as serine/threonine kinase 1 (Akt1), tumor necrosis factor (TNF), interleukin 6 (IL6), vascular endothelial growth factor A (VEGFA), cellular tumor antigen p53 (Tp53) were screened. Pathway analysis showed that the targets of GX in the treatment of phlegm and blood stasis-relate cardiovascular diseases were mainly involved in PI3K/Akt signaling pathway, sphingolipid metabolism, platelet activation, hypoxia inducible factor-1 (HIF-1), ras-proximate-1 (rap1) and other signaling pathways. In addition, molecular docking analysis showed that apigenin, cucurbitacin D, linolenic acid and kaempferol and other key components had potential binding ability with Akt1, TNF, IL6, VEGFA and Tp53. In the animal experiments, compared to the phlegm and blood stasis syndrome group, GX could significantly improve the traditional Chinese medicine syndrome score, blood lipid, vascular endothelial structure disorders and reduce serum endothelin-1 (ET-1) level, increase serum nitric oxide (NO) and endothelial nitric oxide synthase (eNOS) levels, which could restore aortic endothelial function. In addition, the expression of intercellular cell adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) in aorta could be significantly reduced, which could improve the vascular endothelial injury of aorta. Western blot revealed that GX could significantly decrease the phosphorylation levels of phosphoinositide 3-kinase (PI3K) and Akt in aorta. This study revealed the mechanism of GX in treatment of phlegm and blood stasis-relate cardiovascular diseases is consistent with the characteristics of multiple ingredients, multiple targets and multiple pathways. In addition, this study also clarified that the reversal of pathological of phlegm and blood stasis syndrome rats may be related to GX inhibiting PI3K/Akt signaling pathway, which could improve vascular inflammation and vascular endothelial function injury.

Objective To confirm whether taxotere combined with mild hyperthermia will have synergistic effects,and to explore their joint mechanism of action.Methods Firstly the effective concentration of taxotere was determined by using MTT method to observe the effect of docetaxel on proliferation of human breast cancer cell line MCF-7.Then three samples of in vitro cultured human breast carcinoma MCF-7 cells were prepared,termed the the taxotere group,the taxotere plus mild hyperthermia group and the control group,and treated with effective concentration of taxotere exclusively or in combination with mild hyperthermia,or left without any special treatment.The taxotere plus mild hyperthermia group was subdivided into 5 subgroups according to the temperatures used (39.0 ℃,39.5 ℃,40.0 ℃,40.5 ℃,41.0 ℃) MTT assays were used to measure the proliferation and invasive capacity of the cells and their effective concentrations.Flow cytometry was used to detect cell apoptosis rates and any cell cycle changes in the control group.Western blotting was used to detect any changes in the expression of mitogen-activated protein kinases (MAPKs),Bcl-2/Bax,heat shock protein-70 (HSP-70) and P-gp.Results The taxotere with mild hyperthermia group demonstrated a significantly higher rate of apoptosis than that in the taxotere and control groups.There were also more cells in the G2/M phase observed.Combining taxotere with mild hyperthermia was found after 24 h to have significantly increased p-ERK,p-JNK,p38,HSP-70 and P-gp protein levels and to have significantly decreased Bcl-2 protein expression in contrast with the other two groups.Conclusions Combining taxotere with mild hyperthermia showed synergistic effects in vitro.It seemed to be limiting the accumulation of MCF-7 cells in the G2/M phase and activating the signal pathways of MAPKs while inhibiting the activation of Bcl-2/Bax signal pathways.Combining taxotere and mild hyperthermia can accelerate the expression of HSP70 and P-gp in MCF-7 cells.Hyperthermia might induce chemotherapy resistance.

ObjectiveTo explore the correlations of simple bladder capacity measurement and urodynamic examination used for assessing the bladder function of patients with spinal cord injury.Methods From December 2011 to September 2013,a total of 37 patients with spinal cord injury were recruited.Their bladder functions were examined by both simple bladder capacity measurement and urodynamics in the first week after admission.The type of neurogenic bladder,residue urine,bladder capacity and the changes of bladder pressure were documented and compared.Results The simple bladder capacity measurement and urodynamics showed no significant differences in the parameters including residual urine,and bladder pressures when inputting 50mL,100mL,300mL and 400mL water(P>0.05). But there were significant differences in the results of bladder capacity and bladder pressure when inputting 200mL water(P<0.05). The intra-class coefficients between the results by the two methods were 0.606~0.919(P<0.01).The Kappa coefficient of the health professionals’judgments according to the two methods was 0.825(P<0.001).Conclusions The results of simple bladder capacity measurement are reliable.It can be used as the supplement for urodynamics to monitor the bladder function of patients with spinal cord injury.

Objective To retrospectively assess the prognostic impact of diabetes mellitus (DM) on patients with hepatocellular carcinoma (HCC) after curative resection.Methods A total of 417 HCC patients who had undergone curative hepatic resection were included into two groups.108 patients were classified into DM group and 309 patients into the non-DM group.Overall survival,disease-free survival,postoperative morbidity and mortality were compared between the two groups after reducing confounding bias by propensity score matching.Independent prognostic predictors were determined by Cox proportional hazards model.Results Propensity score matching resulted in 89 patients in each group,and variables were balanced between two groups.In the matched cohort,DM and non-DM groups showed similar morbidity and 30-and 90-day mortality after curative hepatectomy (respectively x2 =0.837,x2 =Fisher,x2 =Fisher,all P ＞ 0.05),the 1-,3-,and 5-year overall survival rates were 82.0％,59.9％,and 33.4％ in DM group and 90.7％,79.1％,and 69.3％ in non-DM group,respectively(P =0.001),however,there was no significant difference in disease-free survival between DM and non-DM groups.Cox multivariate analysis revealed that DM is an independent risk factor for overall survival in patients with HCC after curative resection,but not for disease-free survival.Conclusions DM does not increase the postoperative morbidity or mortality for patients with HCC after curative resection,however,DM may increase the risk of mortality of HCC patients in the long-term.
