Objective To investigate the effects of AGEs-RAGE on the apoptosis of GLUTag cells and explore the possiblc mechanism.Methods GLUTag cells treated with 0、100、200、300μg/ml of AGEs for 24h were examined for gene and protein expression of RAGE using RT-PCR and western blotting,respectively.GLUTag cells were randomly divided into four groups:control,200μg/ml AGEs,AGEs+siRNA-RAGE and AGEs+apocynin.The protein expression of p22phox、p47phox 、Bcl-2、Bax in the cells were detected with western blotting.The reactive oxygen species (ROS) levels were examined using 2'7'-dichlorodihydroflur-rescein diacetate (DCFH-DA) and the apoptosis of L cells were tested by AnnexinV-FITC/PI.Results AGEs increased thc cxpression of RAGE in a dose dependent manner.Treatment with AGEs induced a significant increase in the expression of p22phox,p47phoxand the activity of ROS,caused up-regulation of Bax and down-regulation of Bcl-2,which enhanced the apoptosis of GLUTag cells.Apocynin,the inhibitor of NADPH oxidase,prevented those responses and the effects caused by AGEs were abolished by inhibition of RAGE activity with siRNA.Conclusion AGEs positively regulate the exprcssion of NADPH oxidase-derived ROS and its down-steam signaling pathway p53/Bax by targeting RAGE,leading to the apoptosis of GLUTag cells.

Objective To investigate the comprehensive treatment of Crohn's disease complicated with anal fistula.Methods The clinical data of 33 patients with Crohn's disease complicated with anal fistula who were admitted to the Sixth Hospital of Sun Yat-Sen University from June 2007 to April 2011 were retrospectively analyzed.According to the range of the disease,surgical,medical and combined treatment were applied.Surgical treatment included thread-drawing drainage,fistulectomy,incision and drainage of the perianal abscess and enterostomy.Medical treatment include 5-aminosalicylic acid,immunosuppressive therapy,glucocorticoid,tumor necrosis factor monoclonal antibodies.All the patients were followed up till August 2012.The Crohn's disease activity index (CDAI) and perianal Crohn's disease activity index (PDAI) before and after treatment were analyzed using the independent sample t test.Results Of the 33 patients,22 received surgical and medical treatment,7 received surgical treatment,and 4 received medical treatment.The anal fistula was healed in 18 patients after the initial treatment (3 of them did not receive surgical treatment),and the mean closure time of the fistula was (3.2 ± 2.6) months (range,1-12 months) ; the condition of 8 patients was improved ; 4 patients suffered from fistula persistence ; anal fistula recurrence was observed in 6 patients,and the time for anal fistula recurrence was (35 ±56)months (range,5-148 months).The preoperative CDAI and PDAI of the 33 patients were 166 ± 100 (range,7-361) and 9.2 ± 2.6 (range,5-16),and the postoperative CDAI and PDAI of the 33 patients were 83 ± 53 (range,0-212) and 2.7 ± 3.1 (range,0-11).There were significant differences between the pre-and postoperative CDAI and PDAI (t =4.20,8.92,P ＜0.05).Of the 12 patients who were failed in the initial treatment,the anal fistula was healed in 3 patients after the treatment,and the condition of the other 9 patients remained the same.Of the 6 patients with anal fistula recurrence,5 received reoperation (4 were healed and 1 remained the same after the treatment) and the fistula of 1 patient who received medical treatment was not healed.At the end of the follow up,the anal fistulas of 20 patients were healed,and 10 remained the same.Conclusions There is no standard treatment for Crohn's disease complicated with anal fistula,surgical treatment combined with medical treatment is important for the treatment of Crohn's disease complicated with anal fistula.Surgical procedures should be chosen carefully according to the condition of the patients.

OBJECTIVE:To investigate the application and variation trend of biological product and biochemical drugs in hospitals of Chongqing,and to provide reference for further improving rational use of this type of drugs in clinic. METHODS:By using the methods of DDDs analysis and ranking of amount of money,the data on the use of biological products and biochemical drugs collected from 34 hospitals of Chongqing during 2013-2015 were summarized and analyzed statistically. RESULTS:The consumption sum of biological products and biochemical drugs in 34 hospitals from Chongqing during 2013-2015 decreased from 828.01 million yuan to 763.70 million yuan,and their proportion decreased from 9.55% to 7.82%. The consumption sum of Thymopolypeptides injection,Deproteinised calf blood serum injection,Coenzyme complex injection,Ribonucleic acidⅡinjection and Human albumin injection ranked the top 5 places averagely within 3 years. Among them,Thymopolypeptides injection ranked the top 1 in 3 years. DDDs of Thymopolypeptides injection and Deproteinised calf blood serum injection ranked the top 3 places within 3 years,and DDDs of Thymopolypeptides injection had been declining. DDDs of Kallidinogenase injection,Coenzyme Q10 injection,Human albumin injection and Placental polypeptide injection increased year by year. B/A of Thymosin injection in 2013 and 2015 were both 1.00. B/A of Kallidinogenase injection and Coenzyme Q10 injection were far greater than 1 in 3 years;B/A of Human albumin injection and Human immunoglobulin injection were far less than 1 in 3 years,and those of Placental polypeptide injection were also less than 1. CONCLUSIONS:The consumption sum of biological products and biochemical drugs in 34 hospitals of Chongqing during 2013-2015 are in downward trend generally. The clinical application of the main varieties is basically reasonable,but the application of few varieties needs to be strengthened and chosen carefully.

Patellofemoral osteoarthritis (PFOA) is a subtype of knee osteoarthritis that has gained popularity in recent years due to its high prevalence and disease burden. The National Clinical Research Center for Geriatric Disorders (Xiangya Hospital) and the Joint Surgery Branch of the Chinese Orthopaedic Association, together with the editorial department of the Chinese Journal of Orthopaedics, convened a panel of orthopaedic experts to come up with guidelines. Subsequently, the Chinese clinical practice guideline for patellofemoral osteoarthritis (2020 edition) was officially released in September 2020. This is of utmost importance in standardizing the clinical diagnosis and treatment of PFOA in China. The present guideline focused on the diagnosis (symptoms, signs and imaging changes), non-surgical interventions (primary treatment and pharmacotherapy) and surgical interventions (repair and reconstruction) of PFOA. The present interpretation aims to address key emerging clinical issues in the diagnosis and treatment of PFOA in China.
