Chinese Journal of Biochemical Pharmaceutics 2014;(3):91-92,97
Objective To study the regulatory effect of paclitaxel injection on vascular endothelial related factors in serum of uterine cancer patients.Methods 30 cases of uterine cancer patients treated with paclitaxel (observation group)and 30 cases of uterine cancer patients treated with surgery (control group)were selected.Chemiluminescence immunoassay (CLIA)was used to detect expressions of serum tumor necrosis factor(TNF), Interleukin-8(IL-8)and tumor specific growth factor (TSGF).Results Before treatment,there was no significant difference between the serum TNF, IL-8 and TSGF in observation group and control group(P<0.05).At 3 months after treatment,the serum TNF,IL-8 and TSGFwere significantly lower than before treatment ,which was statistically significant(P<0.05).Conclusion Paclitaxel can decrease serum TNF,IL-8 and TSGF in patients with uterine cancer,which provides a new theoretical basis for its anticancer effects.
2.Clinical study on auricular point sticking plus Western medicine for moderate gastric cancer pain
Journal of Acupuncture and Tuina Science 2020;18(4):276-280
Objective: To explore the clinical efficacy and mechanism of auricular point sticking plus Western medicine for moderate gastric cancer pain. Methods: A total of 80 patients were selected and divided into an observation group and a control group according to the random number table method, with 40 cases in each group. Patients in the control group received Western medicine treatment, while patients in the observation group received additional auricular point sticking. Both groups were treated for 2 weeks. Numeric rating scale (NRS) and Karnofsky performance status (KPS) were adopted before and after treatment. The total time and times of flare-up pain in 24 h were recorded. The cyclooxygenase-2 (COX-2) and tumor necrosis factor-α (TNF-α) levels were detected. The clinical efficacy of both groups was evaluated after treatment. Results: The total effective rate of the observation group was significantly higher than that of the control group (P<0.05); after treatment, NRS scores of both groups were significantly lower than those before treatment (both P<0.05), and the score of the observation group was lower than that of the control group (P<0.05); KPS scores of both groups were significantly higher than those before treatment (both P<0.05), and the score of the observation group was higher than that of the control group (P<0.05). After treatment, the total time and flare-up times of pain during 24 h of both groups were significantly reduced (all P<0.05), and those of the observation group were significantly less than those of the control group (both P<0.05). After treatment, the COX-2 and TNF-α levels of both groups were significantly reduced (all P<0.05), and were lower in the observation group than in the control group (all P<0.05). Conclusion: The clinical efficacy of auricular point sticking plus Western medicine for moderate gastric cancer pain is valid. This combined treatment can alleviate cancer pain and improve patients' quality of life, which may be related to its ability to reduce COX-2 and TNF-α levels.

Endophytic fungi which reside in the tissue of mangrove plants seem to play an important role in the discovery of new biologically active substances. During the course of screening for the antimicrobial metabolites from the endophytic fugus Penicillium sp. FJ-1 of mangrove plant Avicennia marina, a new aurone glycoside (1) was isolated by repeated column chromatography on silica gel and recrystallization methods. The structure of 1 was elucidated as (Z)-7,4'-dimethoxy-6-hydroxy-aurone-4-O-β-glucopyranoside, on the basis of spectroscopic analysis. Compound 1 exhibited antifungal activity against Candida sp., with the potency comparable to amphotericin B and much better than fluconazole. Compound 1 can also inhibit extracellular phospholipase secretion in a concentration-dependent manner.

4.Toxic Effects of Brominated Flame Retardants on Human and Mammals
Journal of Environment and Health 1992;0(02):-
Brominated flame retardants (BFRs) are widely used industrial chemicals. Several BFRs were found to be at detectable level in the wildlife as well as in human, however, up to now there were few related papers which could be found for the adverse effects of BFRs on the wildlife, especially, on human. The recent research works on the biological effects of polybrominated diphenyl ethers (PBDEs), tetrabromobisphenol A (TBBPA) or derivates, hexabromocyclododecane (HBCD) and polybrominated biphenyls (PBBs) are reviewed in the present paper.

Objective To evaluate the effect of furosemide on Cl -/HCO- 3 exchange of inner medullary collecting duct(IMCD) in rabbit kidney. Methods The effect of furosemide in different concentrations on the changes in Cl -/HCO- 3 exchange in mono-layer of IMCD cell in rabbit kidney was determined by fluorescent probe technique. Results Cl -/HCO- 3 exchange in IMCD cell could be inhibited by 4.3% by 15?mol/L furo semide solution, and 480?mol/L furosemide solution could inhibit the exchange by 97.4%. The Cl -/HCO- 3 exchange rates of the groups, in which the final concentrations of furosemide were equal to or higher than 30?mol/L, were significantly lower than that of the control group(P

AIM: To investigate the difference of cognitive impairment and depression between age-related macular degeneration ( AMD ) group and the control group patients. ·METHODS: A prospective case-control study was performed from November 2014 to August 2016 in the hospital for AMD patients and sex-matched control group. The Mini-Mental State Examination ( MMSE) and the Geriatric Depression Scale ( GDS ) score of each patient were collected for statistical analyzing. ·RESULTS: There were total 84 cases ( 168 eyes ) included in the study. The difference of visual acuity between the two group was statistically significant ( F=8. 953, P=0. 004) by baseline data analyzing. There were no significant differences in MMSE scores between the two groups according to educational status ( P>0. 05 ) , while the prevalence of cognitive impairment in each group was statistically significant (x2 =4. 14, P=0. 042). The difference of GDS scores, prevalence of total and mild depression between two groups were both statistically significant (F=5. 852, P=0. 018; x2=6. 372, P=0. 012; x2 = 5. 674, P = 0. 017 ). However, there was no statistically significant difference in the prevalence of moderate to severe depression (x2=0. 672, P=0. 412). ·CONCLUSION: AMD patients have a higher prevalence of depression. Although MMSE score differences were not statistically significant in subgroup analysis by educational levels, AMD patients are more likely to have cognitive impairment overall.

The aim of this study is to clarify whether edaravone postconditioning had protective effect against renal ischemia/reperfusion injury and to compare the protective effect between ischemic postconditioning and edaravone postconditioning. Rats were subjected to 45 min ischemia followed by 24 h reperfusion. The rats were randomly assigned to seven groups: a sham-operated control group, an ischemia/reperfusion group, an ischemic postconditioning group, a normal saline vehicle postconditioning group and an edaravone postconditioning (1, 3, and 6 mg x kg(-1)) group. Renal function was assessed by serum creatinine and BUN concentration, while histological damage of renal tissue was assessed with HE staining. MDA content and SOD activity of renal tissue were determined. TUNEL staining was performed to analyze the apoptosis of the tubular epithelial cells, the protein level of Bcl-2 and Bax in renal tissue was examined by Western blotting. Compared to the ischemia/reperfusion group, edaravone postconditioning significantly decreased serum creatinine and BUN concentration, and ameliorated histological damage of renal tissue. MDA was less after 24 h reperfusion in the edaravone postconditioning group than that in the ischemia/reperfusion group, consistent with an increase in SOD activity. In addition, edaravone postconditioning decreased TUNEL-positive cells and Bax expression, and increased Bcl-2 expression. Results detected in the edaravone postconditioning group showed no significant difference from the ischemic postconditioning group. Edaravone administered during the last 3 min of ischemia, prior to reperfusion induces a pharmacological postconditioning in vivo against renal ischemia/reperfusion injury in rats. This protection is similar to that observed with ischemic postconditioning.
