Objective To investigate the effect of sodium hyaluronate (SH) intra-articular injection on the treatment of knee osteoarthritis (OA), andto compare the contents of free radicals and inflammatory factors in joint fluids of pre-and pro-treatment as to explore the treatment mechanism of SH. Methods Ninety-two patients (111 knees) with mild(51)，moderate(35) and serious(25) knee OA were treated with intra-articular injections of SH (20 mg once a week for 5 weeks). According to Lysholm scoring, clinical signs such aspain, swelling,and the ability to walk, squat, run, go upstairs and downstairs were assessed before and after the treatment, and the contents of nitric oxide (NO), superoxide dismutase(SOD), malonic dialdehyde(MDA) and IL-1β、TNF-α in joint fluids from the OA joints before 1st,2nd, and 5th injection and 3 months after each injection were observed. Results All cases were followed up for 3 months. The improvements in the signs and function of knees were excellent in 42 knees, good in 38 knees, fair in 21 knees and poor in 10 knees, with 72.1% excellent and good results. The lighter the illness was, the better the improvement was: the rate of the excellent and good was 92.1% in mild group, 68.6% in moderate group and 42.9% in serious group. The contents of oxygen free radicals and IL-1β、TNF-α of the patients with mild and moderate OA decreasedmarkedly after being treated with SH（Plt;0.05）, but these decreased lightlyin serious OA group（Pgt;0.05）. SH had mild effect on the contents of NO. Three months after treatment, only in mild OA group the contents of NO significantly decreased（Plt;0.05）, and no significant change in moderate and serious groups was observed（Pgt;0.05）. Conclusion SH intraarticular injection has a positive effect on the relief of clinical symptoms and on the improvement of articular function of knee OA. The therapeutical effect of SH on OA is achieved possibly by decreasing the contents of free radicals especially oxygen free radicals and inflammatory factors in joint fluids.

Abstract： Objective To summarize the methods and results of supra-annular aortic valve replacement（AVR） in patients with severely damaged aortic annulus. Methods Supra-annular AVR was performed in 5 patients between March 2008 and Dec. 2010 in Changhai Hospital, Second Military Medical University. There were 4 males and 1 female with their mean age of 46.3 years (ranging from 38 to 53 years). Non-specific infectious diseases were diagnosed in 4 patients who had severe paravalvular leakage after their first AVR operations (2 patients with Behcet’s disease and 2 patients with arteritis), and one patient had severe infectious endocarditis. All the patients had severely destroyed aortic annulus and could not undergo routine AVR. The prosthetic valves were fixed to the aortic sinus wall between the annulus and coronary arterial ostia, and the sutures passed through from the outside of aortic wall into the inside and prosthetic valve ring. Coronary artery bypass grafting was performed if the coronary ostium was involved. Results All patients recovered from the operations uneventfully, and were followed up from 6 months to 3 years. All patients were in New York Heart Association（NYHA） functional class Ⅰ or Ⅱ during the follow-up period, and paravalvalar leakage, pseudoaneurysm and aortic root aneurysm were not found by the examination of 3D computed tomographic angiography and echocardiography at 6 months（4 cases）, 1 year（2 cases）, and 3 years（1 case）, respectively . Conclusions Supra-annular AVR is an alternative surgical method for patients with severely damaged aortic annulus. The procedure is simple and effective to prevent paravalvular leakage and pseudoaneurysm formation.
【Abstract】ObjectiveTo explore the mechanisms of anabolism intensified by recombination human growth hormone (GH) on the basis of total parenteral nutrition (TPN) during postoperative in gastrointestinal carcinoma patients. MethodsNinety-four gastrointestinal carcinoma patients undergone operation were randomly divided into TPN group and TPN+GH group. The levels of TNF-α, IL-1, IL-6 and CRP were detected in the first, third, seventh postoperative day. ResultsThe levels of TNF-α, IL-1, IL-6 and CRP were significantly lower in TPN+GH group than those in the TPN group at the first, third, seventh postoperative day （P＜0.01）. The levels of TNF-α, IL-1, IL-6 and CRP were significantly higher at the indicated time of postoperative days than the pre-operative days in the two groups (P＜0.01）. ConclusionBy inhibiting TNF-α, IL-1, IL-6 and CRP production in gastrointestinal carcinoma patients undergone operation and blocking high catabolism induced by inflammatory cytokines, GH promotes the synthesis of anabolism.
ObjectiveTo summarize the recent progress in studies of intestinal immunity in inflammatory bowel disease (IBD). MethodsThe literatures on studying the intestinal immunity in IBD, including ulcerative colitis and Crohn disease were reviewed and analyzed. ResultsIBD comprised two main diseases that cause inflammation of the intestines: ulcerative colitis and Crohn disease. Although the diseases had some features in common, there were some important differences in clinical symptoms and pathological features. Accumulating evidence suggested that IBD results from an inappropriate inflammatory response to intestinal microbes in a genetically susceptible host. Immunity studies highlighted the importance of host-microbe interactions in the pathogenesis of these diseases. Prominent among these findings were genomic regions containing nucleotide oligomerization domain 2 (NOD2), autophagy genes, miRNAs, and components of the interleukin-23/type 17 helper T-cell (Th17) pathway. The disfunction of the intestinal microbiome, intestinal epithelium, intestinal immune cells, and the intestinal vasculature played a key role in the process of IBD. The treatment with monoclonal antibody had been introduced to treat IBD and had been certificated effective. ConclusionThe study of basic intestinal immunity and regulation network of molecules in pathogenic process of IBD provides theory basis on prevention of IBD, while related genes of IBD can offer more gene therapy targets.
Objective To explore the application of two methods of direct fecal detection ofClostridium difficilein patients with recurrent inflammatory bowel disease (IBD), including nucleic acid amplification test (NAAT) and enzyme immunoassay (EIA), in order to provide support for hospitals to prevent and control clostridium difficile infection (CDI). Methods Fresh feces of 48 patients with recurrent IBD treated between November 2014 and April 2015 were collected within 48 hours after admission. Anaerobic culture and identification, NAAT and EIA were used to test the same samples. Statistical analysis was performed using Kappa test. Results Among the 48 fecal samples,Clostridium difficilewas negative in 37 and positive in 11 including 2 (4.2%) with toxigenicClostridium difficile characterized as toxin type A+B+. Compared with anaerobic culture and identification, NAAT had a perfect correlation (Kappa=1.00,P<0.05), and EIA had an almost perfect correlation (Kappa=0.89,P<0.05). But EIA toxin test had missed detection of toxigenic samples. Conclusions For patients with recurrent IBD combined with CDI, both NAAT and EIA test may be applied to detctClostridium difficile in feces directly, while NAAT may show a better performance. Samples from highly suspected patients with negative toxin result tested by EIA should be confirmed by other methods such as NAAT.
Objective To explore the role of macrophage-stimulating protein ( MSP) and receptor tyrosine kinase RON in the airway inflammation of chronic obstructive pulmonary disease( COPD) , and investigate its possible mechanism. Methods The rat COPDmodel was established by exposing the rats to cigarette smoke daily for three months. Rat alveolar macrophages ( AMs) were isolated in vivo and cultured,and then challenged with different concentrations of MSP for 24 hours. The concentrations of MSP in broncho-alveolar lavage fluid ( BALF) and serum, and the levels of IL-1β, TNF-α, IL-8, and IL-10 in the supernatants were measured by ELISA. The expression of RONmRNA in lung tissue was assessed by reverse transcription-polymerase chain reaction. The levels of RON protein in the lung tissue and AMs cultured in vitro were observed by immunohistochemistry. The activity of superoxide dismutase ( SOD) and malondialdehyde ( MDA) content in the culture solution were measured with chromatometry method. Results Compared with the control group, the concentrations of MSP in serum and BALF of the COPD rats were significantly higher ( P lt;0. 01) . The levels of RONmRNA and RON protein in the COPD rats were also upregulated significantly ( P lt; 0. 01) . MSP evoked the AMs isolated from the normal and COPD rats to generate more content of MDA and caused a reduction in activity of SOD. In addition, MSP stimulated TNF-α, IL-8, IL-1βand IL-10 release fromAMs of the normal and COPD rats dose-dependently. The levels of TNF-α, IL-8, and IL-1βwere higher, while the level of IL-10 and the SOD activity were lower in AMs of the COPD group than those of the control group in the same dose of MSP ( P lt;0. 01) . The more significant increase in the levels of TNF-α, IL-8, IL-1β, and the more notable decrease in the activity of SOD was found in the COPD group compared with the control group. But the degree of increasing MDA and IL-10 in the AMs of the COPD group was lower than that in the control group. Linear correlation analysis showed that the MSP concentration and the RON protein level in the COPD rats were positively associated with the total cellcounts and AM counts in BALF, and were related to the indexes for pulmonary emphysema. Conclusions There is a close correlation between the MSP and receptor tyrosine kinase RON with the airway inflammation of COPD. The mechanism might be that MSP promote the macrophages release inflammatory factors and increase the production of oxygen free radicals.
ObjectiveTo systematically review the effect of compound Danshen dripping pills combined with Western medicine on inflammatory factors and cardiac function after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction.MethodsDatabases including CNKI, WanFang Data, VIP, CBM, PubMed, Web of Science, EMbase and The Cochrane Library were searched for randomized controlled trials of compound Danshen dripping pills combined with Western medicine in the treatment of acute myocardial infarction after PCI. The retrieval time was from the establishment of the databases to June 11th, 2020. Two reviewers independently screened literature, extracted data and evaluated the risk bias of included studies. RevMan 5.3 software was used for meta-analysis.ResultsA total of 16 studies were included, involving 2 069 patients. The results of the meta-analysis showed that the combination of compound Danshen dripping pills could increase the left ventricular ejection fraction (MD =?4.74, 95%CI 4.07 to 5.42, P<0.01), decrease the B-type natriuretic peptide (SMD=?3.81, 95%CI ?5.06 to ?2.57, P<0.01), the level of interleukin-6 (SMD=?3.20, 95%CI ?4.54 to ?1.86, P<0.01) and level of tumor necrosis factor-a (SMD=?4.96, 95%CI ?7.03 to ?2.89, P<0.01).ConclusionsCurrent evidence suggests that the combination of compound Danshen dropping pills has potential benefits in inhibiting inflammation and improving cardiac function after PCI. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
Inflammatory bowel disease (IBD) is characterized by recurrent abdominal pain, diarrhea, and mucopurulent bloody stools as its main clinical manifestations. In recent years, its parenteral manifestations have received increasing attention. Fatigue, as one of the extraintestinal manifestations of IBD, affects the quality of life of patients, and results in considerable distress for patients. The influencing factors of fatigue symptoms in IBD patients include inflammation, psychological comorbidities, sleep disorders, anemia, micronutrient deficiency, changes in microbiota, and metabolomics. The pathogenesis is currently unclear and may be related to disorders in tryptophan metabolism. This article will review the influencing factors and pathogenesis of fatigue symptoms in IBD patients, aiming to provide a basis for the prevention and treatment of IBD fatigue.
