1.The effect of ischemia-reperfusion injury on concentrations of free amino acids in rat myocardium and taurine's protective role
Chinese Pharmacological Bulletin 1987;0(02):-
By using the model of ischemia-reperfusion injury in the isolated working rat heart,the change of free amino acid concentrations in myocardium and the effect of taurine on the heart were investegated. It was found that concentrations of 17 free amino acids in myocardium, except Cys,decreased,and that 20mM taurine was able to ameliorate the ischemia-reperfusion injury of the heart ;e. g. , the improvement of recovery of cardiac mechanical functions, the decrease in the leakage of LDHand CK from myocardium,in the accumulation of lipid peroxides and calcium,and in the loss of free amino acids in myocardium,as well as the decrease in the occurence rate of ventricular arrhythmias during the reperfusion phase. So, it may be suggested that exogenous taurine has some protective effects against the myocardial is-chemia-reperfuaion injury.

Objective: To evaluate the cytotoxic effect of PEM? induced by HSPgp96 on anti-tumor in vitro. Methods; PEM? separated from mice induced by thioglycolate were divided into three groups randomly: Culture medium in control; LPS-induced group; HSPgp96-induced group. The production of NO, the cytotoxic effect to H22 cells and the morphologic change of PEM? were investigated separately by enzyme method, MTT assay and scanning electron microscope. Results: In vitro, HSPgp96 can increased NO production from PEM? of mice and significantly enhance the cytotoxic effect of PEM? to H22 cells as well as LPS. Conclusion: HSPgp96 can effectively induce the cytotoxic effect of PEM? on anti-tumor in which NO is one of the capital effective molecules in vitro.

AIM: To investigate the antitumor effect and mechanism of trichosanthin (TCS) on melanoma B-16 cells. METHODS: (1) The injury of B-16 cells by trichosanthin was observed with SCGE and hoechst33258 staining method. (2) LCSM and specificity fluorescent probe Fluo-3/AM, H2DCF-DA, DAF-FM diacetate were applied to analyze the dynamic changes of Ca2+, ROS and NO in single cell cultured with TCS. Simultaneously, the relationship between ROS, NO and increase of Ca2+ was also revealed. RESULTS: (1)When treated with TCS (50 mg/L) for 3 h and 6 h, neither cytotoxicity assay nor SCGE showed the differences compared with control group. After 12 h incubation, specificity phenomena of DNA injury-comet tail appeared in SCGE and chromatin condensation even apoptotic body formation were seen by Hoechst33258 staining. (2) TCS (50 mg/L) evoked rapid enhancement of the production of Ca2+, ROS and NO in the cell and the differences between TCS and control group had statistical significance (P

Objective To investigate the association of serum C peptide concentration with the severity and the outcome of diabetic foot ulcer (DFU). Methods The clinical data of 257 inpatients with DFU were collected, including fasting and postprandial 2h C peptide levels and C peptide area under curve (AUCCP ). The patients were followed up on the outcomes of ulcers and death. The associations of serum C peptide concentration with the Wagner degree, infection severity, and healing rate were analyzed. Results The medians of fasting and 2h postprandial serum C peptide as well as AUCCP were 1. 37(0. 02 ~ 9. 00) nmol/ L, 3. 22(0. 02 ~ 29. 61) nmol/ L, and 511. 65 (3. 60 ~ 2 691. 30)nmol·min-1 ·L-1 respectively, which were lower than general levels. The time of follow-up in our study was 2. 8 (1. 0 ~ 5. 1) years. By the end of study, the wound of 75. 88% patients was healed, 3. 5%undergone major amputation, and 23. 74% died. After adjusting for relative factors, there were no significant associations of serum fasting and postprandial C peptide levels and AUCCP with Wagner degree and infection severity (P>0. 05). Cox regression analysis showed that the fasting plasma C peptide and hemoglobin were the independent protective factors for the healing of ulcers; old age, male, higher infection degree, and diabetes family history were their independent risk factors ( all P < 0. 05). Conclusions The lower plasma fasting C peptide concentration in patients with DFU is not correlated with Wagner degree and infection severity, but closely related with healing rate.

Inflammatory bowel disease (IBD) is a chronic non-specific intestinal inflammatory disease of unknown etiology, which is characterized by recurrent episodes and prolonged refractory recovery. Financial toxicity refers to the objective economic burden and subjective economic distress caused by medical expenses caused by the disease to patients. IBD patients show a certain level of financial toxicity due to frequent visits to doctors for a long time. This article reviews the concept of financial toxicity, evaluation tools and the current status of financial toxicity in IBD patients, analyzes the influencing factors of financial toxicity in IBD patients from the aspects of general demography factors, disease and treatment and psychosocial aspects, summarizes and puts forward the countermeasures of toxicity of IBD patients to reduce the economic and the direction of the future study, so as to provide reference for related research.

Objective:To deeply explore the supportive care needs of patients with inflammatory bowel disease, in order to provide reference for the development of supportive care strategies.Methods:A qualitative description was conducted based on the supportive care needs framework. Objective sampling method was used to select 17 patients with inflammatory bowel disease from the First Affiliated Hospital with Nanjing Medical University from August to November 2021 for semi-structured in-depth interview and directed content analysis was used to analyze the interview data.Results:The final analysis yielded a total of 5 categories. These were physiological need, information need, practical (daily life) need, emotional and social support need, psychological and spiritual needs. They were all within the framework of supporting care needs.Conclusions:In the future, targeted education and diversified social support should be implemented based on the needs of patients with inflammatory bowel disease and from the perspectives of hospital, family members and peers.
