ABSTRACT
Acute coronary syndrome (ACS) is one of the leading causes of death in cardiovascular disease. Percutaneous coronary intervention (PCI) is an important method for the treatment of coronary heart disease (CHD), and it has greatly reduced the mortality of ACS patients since its application. However, a series of new problems may occur after PCI, such as in-stent restenosis, no-reflow phenomenon, in-stent neoatherosclerosis, late stent thrombosis, myocardial ischemia-reperfusion injury, and malignant ventricular arrhythmias, which result in the occurrence of major adverse cardiac events (MACE) that seriously reduce the postoperative benefit for patients. The inflammatory response is a key mechanism of MACE after PCI. Therefore, examining effective anti-inflammatory therapies after PCI in patients with ACS is a current research focus to reduce the incidence of MACE. The pharmacological mechanism and clinical efficacy of routine Western medicine treatment for the anti-inflammatory treatment of CHD have been verified. Many Chinese medicine (CM) preparations have been widely used in the treatment of CHD. Basic and clinical studies showed that effectiveness of the combination of CM and Western medicine treatments in reducing incidence of MACE after PCI was better than Western medicine treatment alone. The current paper reviewed the potential mechanism of the inflammatory response and occurrence of MACE after PCI in patients with ACS and the research progress of combined Chinese and Western medicine treatments in reducing incidence of MACE. The results provide a theoretical basis for further research and clinical treatment.

A 28?year?old, healthy male presented with blurring of vision in the right eye following third dose of the AstraZeneca/ COVISHIELD vaccine. Further examination revealed ischemic central retinal vein occlusion, and subsequent laboratory investigations were inconclusive for his eye disease. He responded to pulse corticosteroid and tapering doses of oral corticosteroids without requiring any intra?vitreal injection. Twelve articles were identified with the help of a PubMed literature search, and a short review of these patients was performed. Retinal vein occlusion can occur because of inflammation?induced thrombosis after coronavirus disease 2019 vaccination and may respond to anti?inflammatory therapy
ABSTRACT
Anti-inflammatory therapy is generally considered to be prior to surgery for Takayasu disease to achieve better outcomes. We report two Takayasu arteritis patients with thoracic aneurysm. Case 1 was a 19-year-old woman who presented acute trachyphonia for one month. CT revealed aortic arch aneurysm of which maximal diameter was 64 mm with partial cystic protrusion. We performed urgent total arch replacement before anti-inflammation therapy was induced. Postoperative course was uneventful and the patient discharged on steroid therapy. Case 2 was a 35-year-old woman who complained chest pain for two weeks. CT revealed a Valsalva aneurysm with maximal diameter 54 mm and the aortic wall of the arch including its branches was surrounded by thick low density area. As the FDG-PET confirmed inflammatory arteritis, initial steroid therapy was planned. However, one day before admission, the patient presented acute aortic dissection and did not respond to any resuscitation. We conclude that the right time of surgery or the initial induction of anti-inflammatory therapy for anuerysmal dilation by Takayasu arteritis is to be determined based not only on the inflammation level but also on aneurysmal size and the patient's severity of complaints.
ABSTRACT
Objective To study the effects of diacerein and its metabolite rhein on plasma inflammatory cytokine level and expression of perirenal adipose tissue chemerin in type 2 diabetes mellitus (T2DM) rats and its role in regulating glucose and lipid metabolism.Methods We randomly divided 56 SD male rats into 5 groups: normal control group (Group A), T2DM group (Group B), pioglitazone group (Group C), diacerein group (Group D), and pioglitazone+diacerein group (Group E).Group A was fed with ordinary feed whereas the other groups were fed with high-fat diet.At the end of week 8, rats in Groups B, C, D and E were injected intraperitoneally with 30mg/kg of STZ solution to create the model.Those in Group A were injected with the same volume of sterile sodium citrate solution.OGTT examination was taken to screen the model rats at the end of week 10.The successful mode was chosen according to OGTT result.Then Group C was treated with pioglitazone 10mg/(kg·d) orally, Group D with diacerein 50mg/(kg·d), Group E with pioglitazone 10mg/(kg·d)+diacerein 50mg/(kg·d), and Group A and B were given the same volume of normal saline.The intervention lasted 4 weeks.At the end of experiment weeks 10 and 14, FBG, FINS, TC, TG, LDL-C, IL-1β, IL-6, and TNF-α were detected in the fasting rats with free access to water.After blood sample was taken at the end of week 14, all rats were killed and theperirenal adipose tissue was isolated, the expression of chemerin in perirenal adipose tissue was detected by Western blotting.Results At the end of week 10, FBG, FINS, TG, TC, LDL-C, IL-1β, IL-6, and TNF-α were higher in Groups B, C, D and E than in Group A while HDL-C was lower (all P<0.01).At the end of week 14, TC, TG, and LDL-C were lower in Groups C, D and E than in Group B but higher than Group A while HDL-C was lower than in Group A (all P<0.05).Group E had greater changes in glucose and lipid metabolism and inflammatory cytokine level than Groups C and D (P<0.05).Western blotting results showed that the expression of chemerin in perirenal adipose tissue increased higher in Group B than in Groups A, C, D and E (P<0.05).The expression of chemerin were also higher in Groups C and D than in Groups A and E (P<0.05), but there was no significant difference between Groups A and E.Conclusion Diacerein can regulate the metabolism of glucose and lipid, improve insulin resistance by reducing the expression of chemerin and the level of inflammatory cytokines.
ABSTRACT
Acute spinal cord injury can lead to severe motor,sen-sory and sphincter muscle dysfunction.Inflammatory response caused by inflammatory cytokines plays a crucial role in the oc-currence and development of secondary damage.Maintaining the body balance between inflammaion and anti-inflammation through an appropriate anti-inflammatory intervention will be an important strategy for drug therapy of spinal cord injury.This paper mainly introduces the cause,process and participation of inflammatory response in the pathophysiological mechanism of acute spinal cord injury,and also reviews the latest progress of experimental research of anti-inflammatory drugs,aiming to provide reference for finding the safe and effective drugs.
ABSTRACT
Inflammation is a defensive reaction and the most common pathological manifestation of dry eye.In addition,excessive inflammatory response is considered to be the most common pathogenic factor and main cause of dry eye.Currently,the active mechanism of anti-inflammatory drugs has been well-known,and topical antiinflammatory therapy for dry eye is exerting a role at certain extend.However,some adverse responses of these drugs are emerging during the treating procedure.Therefore,it is emphasized that a large sample size of and multicenter randomized-controlled clinical trial is needed to identify the different effects of various anti-inflammatory drugs for different types of dry eye diseases,which will offer a basis for standardized anti-inflammatory treatment for dry eye.
