1.Research progress of endoplasmic reticulum stress in diabetic cardiomyopathy
Chinese Pharmacological Bulletin 2017;33(9):1200-1203
Diabetic cardiomyopathy(DCM) is a disease independently related with coronary artery atherosclerotic heart disease, hypertensive heart disease, valvular heart disease, congenital heart disease and other heart diseases that are uniquely associated with diabetes mellitus, and the pathological manifestations of DCM are mainly myocardial hypertrophy, interstitial fibrosis, necrosis and apoptosis.Endoplasmic reticulum is the central location of many important cellular functions, and endoplasmic reticulum swelling and functional disorder in diabetic cardiomyocytes, high blood sugar can cause endoplasmic reticulum stress, suggesting that endoplasmic reticulum stress(ERS) may be involved in the pathogenesis of diabetic cardiomyopathy and development.Based on this, this paper summarizes the progress of ERS in diabetic cardiomyopathy from the pathogenesis of diabetic cardiomyopathy, unfolding protein reaction and the related role of ERS in DCM.

Objective To investigate the role of platelet rich plasma (PRP) on free fat graft's survival in a rat model.Methods Twenty-four rats were used in the experiment.For each rat,three groups of free fat grafts were injected into the subcutaneous layer of dorsum.Group A was the control group with 0.5 ml fat and 0.12 ml normal saline.Group B received 0.5 ml fat and 0.1 ml PRP with 0.02 ml normal saline.Group C was given combination of 0.5 ml fat and 0.1 ml PRP which was activated by 0.02 ml calcium chloride.Eight rats were euthanised using pentobarbital sodium each time,1,2 and 3 months after fat transplantation.Specimens were acquired and stained with haematoxylineeosin,and then the histological changes examined using light microscopy.All the data were statistically analysed using paired t test to determine if there were differences between the study groups.Results Compared the volume of the fat grafts at 1 month,there was no deference between the groups(P>0.05).However,the diameter of group C was significantly higher than group A (P<0.05).On histological examination,larger vascular density was observed in group C compared with group A at 1 month (P<0.05).And reduced inflammatory reaction was also observed in group C at 3 months(P<0.05).While other histological parameters were not statistically significant (P>0.05).Conclusions PRP does not enhance the survival of fat graft in the Wistar rat model.

BACKGROUND:The degradation of extracellular matrix, which is mediated by matrix metal oproteinases, plays a crucial role in the corneal neovascularization. Tissue factor pathway inhibitor 2, a new type serine proteinase inhibitor, can effectively inhibit the activity of matrix metal oproteinases.
OBJECTIVE:To elucidate the effect of tissue factor pathway inhibitor 2 on the expressions of matrix metal oproteinases in keratocytes in vitro.
METHODS:Rabbit keratocytes were primarily cultured and subcultured in vitro. Plasmid vector pBos-Cite-neo/TFPI-2 was transfected into keratocytes with Lipofectamine 2000. The positive cells were selected using G418.
RESULTS AND CONCLUSION:The results of reverse transcription-polymerase chain reaction, western blot analysis and gelatinase zymography analysis showed that, expression of mRNA and protein of tissue factor pathway inhibitor 2 was upregulated in the transfected keratocytes (P<0.05), while activity of matrix metal oproteinase 1 and 2 was significantly decreased (P<0.05). Experimental findings indicate that that tissue factor pathway inhibitor 2 strongly inhibits the activity of matrix metal oproteinase 1 and 2 in keratocytes.

OBJECTIVE:To explore the role of clinical pharmacists in the therapy for patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) complicated with allergic bronchopulmonary aspergillosis (ABPA). METHODS:Clinical pharmacists participated in the therapy for a AECOPD patient with ABPA. According to patient's con-dition,clinical pharmacists suggested adjusting the inhalation order of salbutamol and budesonide aerosol inhalation;stop-ping cefatriaxone and adjusting to intravenous injection of voriconazole;and then adjusting voriconazole to oral dosage form timely,monitoring therapy duration. Clinical pharmacists paid close attention to therapeutic efficacy and ADR,and provided medication education for patients. RESULTS:Physicians adopted the suggestion of clinical pharmacists to adjust inhalation order of aerosols,the dosage and route of administration of voriconazole. The patient's condition was improved obviously,and the drug therapy was continued after discharge. CONCLUSIONS:Clinical pharmacists participating in the whole process of treatment improves therapeutic efficacy,reduces the occurrence of ADR and promotes rational drug use in clinic.

Objective To observe the curative effect of pricking bloodletting combined with acupuncture on patients with piriformis injury syndrome.Methods A prospective randomized controlled clinical trial was conducted, 84 patients with piriformis injury syndrome admitted to the Department of Acupuncture and Massage in the First Affiliated Hospital of Xinjiang Medical University from May 2011 to May 2014 were enrolled, and they were divided into observation group and control group by random number table, each group being 42 cases. The patients in the observation group were treated with bloodletting once a week (after bloodletting no other treatment was given), and then once a day of acupuncture was performed for 4 days in a week, completing one therapeutic course; while in the control group, the patient was treated with routine acupuncture once a day for 5 days in a week, finishing one therapeutic course. The interval between two therapeutic courses was 2 days, two courses were carried out, and afterwards the clinical therapeutic effects were evaluated in the two groups. The changes of visual analogue scale (VAS) of two groups before and after treatment and the therapeutic effects were observed.Results The VAS score of the two groups after treatment was lower than that before treatment, and the degree of decrease of VAS score in the observation group was significantly lower than that of thecontrol group (1.50±1.35 vs. 2.69±1.68,P < 0.01); the total effective rate in the observation group was obviously higher than that in the control group [100.00% (42/42) vs. 69.05% (29/42),P < 0.01].Conclusion Pricking bloodletting combined with acupuncture therapy for treatment of piriformis injury syndrome can shorten the course of treatment.

Aim To explore the role of nicotinamide adenine dinucleotide phosphate ( NADPH ) oxidase in high fat-induced injury in MIN6 isletβ cells. Methods MIN6 islet β cells were exposed to different concen-trations of palmitic acid ( 0. 1 , 0. 3 , 0. 5 , 0. 8 mmol · L-1 ) for 48 h and different time points of 0. 5 mmol· L-1 palmitic acid(24,48,72,96 h). Cell viability was measured by MTT, the protein expression of NADPH oxidase subunits such as p22 phox , p47 phox , p67 phox and gp91 phox and apoptosis related proteins such as Bcl-2 and Bax were determined by Western blot. Results MIN6 islet cells exposed to palmitic acid at 0. 5 mmol ·L-1 for 48 h showed a decrease in their viability and an increase in the expression of NADPH oxidase sub-units(p22phox、p47phox、p67phox and gp91phox) and Bax(P<0. 05 ) , while Bcl-2 expression was significantly re-duced. the pretreat with NADPH oxidase inhibitor di-phenyliodonium( DPI,10 μmol · L-1 ) significantly in-hibited high fat-induced Bcl-2 and Bax expression( P<0. 05 ) . Conclusion Activated NADPH oxidase might play an important role in the treatment of high fat-in-duced injury in MIN6 islet cells.
