OBJECTIVE To assess the adherence ability of Candida albicans to two denture base resins with different surface roughness.METHODS In adhesion assays,two denture base resins were made into standard test samples with different surface roughness.Suspension of C.albicans(ATCC 10261) strain was used to adhere on the test samples,and cultured to observe the adhesive effect of a mixed salivary pellicle with Candida to these surfaces.RESULTS In glass surface group,the amount of C.albicans adhering to heat-curing denture base resins was 15.33?2.80,and the amount of C.albicans adhering to Valplast flexible denture resin was 13.67?2.94;In gypsum surface group,the amount of C.albicans adhering to heat-curing denture base resins was 22.67?4.84,and the amount of C.albicans adhering to Valplast flexible denture resin was 21.17?3.31.Significantly greater adhesion of C.albicans to rough surfaces rather than smooth surfaces of the same material was found,at the same time C.albicans had different adhesive ability on different denture base resins(P

Objective To investigate the relationship between the microsatellite polymorphism of cytotoxic T lymphocyte associated antigen-4 (CTLA-4) gene and inflammatory bowel disease(IBD) patients in Zhejiang province. Methods One hundred and eighteen IBD patients without consanguinity (99 patients with ulcerative colitis, 19 patients with Crohn's disease) and 140 healthy controls were studied. The (AT) repeats in the 3' untranslated region of exon 4 of CTLA-4 gene were amplified by allele-specific PCR. The amplified products were electrophoresed with 12% polyacrylamide gel, followed by silver staining. Results Twenty alleles were found in IBD patients and healthy controls. The frequency of 122 bp allele was higher in patients with ulcerative colitis (P=0.0001/Pc=0.0025, OR= 11.393, 95% CI:2.574-50.429) and Crohn's disease (P=0.0003/Pc=0.0050, OR=21.061, 95% CI:3.927-112.94) than that in healthy controls. Conclusion CTLA-4 gene microsatellite polymorphism was obviously associated with IBD in Zhejiang province.

OBJECTIVETo explore the clinical efficacy of the arthroscopic Mender II stapler for the treatment of patients with meniscus anterior horn injury needing meniscal suture repair.

METHODSAmong 47 patients with meniscus anterior horn injury, 29 patients were male and 18 patients were female, ranging in age from 12 to 31 years old, with a mean age of (20.53± 4.12) years old. The duration of disease ranged from 3 to 35 days, and the average duration was (12.43±5.74) days. The Mender II stapler was used to carry out arthroscopic suture from outside to inside. The Lysholm knee scoring system was used to evaluate and analyze preoperative and postoperative symptoms, such as pain, limping embolism and so on.

RESULTSForty-six patients were followed up, and the duration ranged from 12 to 48 months, with a mean of (20.53±4.12) years. The incision healed at the first stage without important vessels and nerves injuries. The symptoms of the locked knee joint disappeared, and symptoms such as pain, limp, swelling and limitation of activity improved. The Lysholm score increased from preoperative 52.33±7.31 to postoperative 86.74±6.92.

CONCLUSIONUsing Mender II stapler to treat patients with meniscus anterior horn injury who were treated with arthroscopic suture from outside to inside is effective to improve symptoms, and to obtain good short-term results.

To build the Dendrobium nobile -T2DM network, and elucidate the molecular mechanism of D. nobile to type 2 diabetes (T2DM). Collect the chemical composition of D. nobile and the targets on T2DM by retrieving database and documents, build the network of D. nobile to T2DM using the entity grammar systems inference rules. The molecular mechanism of D. nobile to T2DM includes: (1) regulating lipid metabolism by lowering triglyceride; (2) reducing insulin resistance; (3) protecting islet cells; (4) promoting the glucose-dependent insulin tropic peptide (GIP) secretion; (5) inhibiting calcium channel. Under the guidance of network pharmacology, through entity grammar systems inference rules we elucidate the molecular mechanism of D. nobile to T2DM, and provide the basis for the further development of health care products based on D. nobile.

With patients' general situation, medication use, occurrence time of adverse drug reaction/event (ADR/ADE), clinical manifestations and prognosis as reference items, a retrospective study was made for 315 cases with ADR/ADE induced by Gastrodin in Chongqing from January 2008 to June 2014, in order to analyze the characteristics of ADR/ADE and provide reference for rational clinical medication. The results showed that among the 315 cases with ADR/ADE, 143 cases (45.4%) were males and 172 cases (54.6%) were females, most of them (74.9%) were aged above 45; 60 cases (19.0%) with ADE were caused by off-label indications and 66 cases (21.0%) with ADE were caused by over dosage; ADR/ADE cases induced by intravenous drip mainly happened within 30 min (85.5%), ADR/ADE cases induced by oral administration mainly happened within 2 h (74.4%), and all of ADR/ ADE cases induced by intramuscular injection happened within 10 min. Totally 593 ADR/ADE cases were reported, which were mainly damages in gastrointestinal system, skin and its adnexa; And 61.9% of ADR/ADE cases were newly reported. It is suggested that medical workers shall learn about the regularity and characteristics of ADR/ADE induced by gastrodin, apply it in clinic with standards, pay close attention to changes of patients' situations and attach importance to the monitoring of ADR/ADE, so as to enhance the safety of medication.

Background:Gastrointestinal carcinoids are prone to be neglected in clinical practice because of the poor specific symptoms in early stage. Aims:To analyze the clinicopathological characteristics,treatment modalities and prognosis of a series of cases of gastrointestinal carcinoids for strengthening the understanding of the disease. Methods:A total of 116 patients diagnosed as gastrointestinal carcinoids by pathology from Jan. 1997 to Jan. 2010 in 8 hospitals at Wuhan were enrolled in this retrospective study. Data on sex,age,major symptoms,diagnostic approaches,treatment modalities, pathological features and prognosis, etc. were collected and analyzed. Results:The most common sites of the gastrointestinal carcinoids were rectum(59. 5%)and stomach(19. 8%);the most common symptoms were abdominal pain,abdominal distention and hematochezia. The positivity rates of immunohistochemical marker NSE,Syn and CgA were 92. 7%,87. 5% and 62. 5%,respectively. The proportion of stomach carcinoids with diameter larger than 2 cm was 73. 9%, and that of rectal carcinoids was only 13. 0%(P <0. 001). Most of the gastric carcinoids(81. 8%)infiltrated into or breakthrough the serosa;the rate of lymph node involvement in gastric carcinoids was significantly higher than that in rectal carcinoids(72. 7% vs. 17. 1%,P<0. 001),while typical carcinoids were less common in stomach than in rectum(60. 9%vs. 95. 7%,P<0. 001). Only one(4. 3%)gastric carcinoid patient underwent endoscopic therapy,while that for rectal carcinoids was 24 cases(34. 8%,P=0. 003). Surgical operation was the main therapeutic method for both gastric and rectal carcinoids. The 3-and 5-year survival rates for rectal carcinoids were 92. 8% and 62. 3%,respectively,and those for gastric carcinoids were 62. 6% and 49. 2%,respectively;there were no significant differences between the two groups(P>0. 05). Conclusions:Gastrointestinal carcinoids enrolled in this study distributed mainly in rectum and stomach. As compared with rectal carcinoids,gastric carcinoids were more advanced in disease stage with poorer prognosis. Regular health checks, strengthening the understanding of the disease,and grasping the specificities of carcinoids distributed at different sites might be helpful for the early diagnosis and treatment of gastrointestinal carcinoids,thus improving the survival rate.

Objective To analyze and explore the clinical features,pathological characters,treatment and prognosis of rectum carcinoid.Methods From January 1997 to January 2010,69 pathologically diagnosed rectum carcinoid cases were collected from Union Hospital of Tongji Medical College,Huazhong University of Science and Technology and other 7 hospitals.The clinical features,pathological characters,treatment and prognosis were analyzed. Results Of 69 rectum carconid cases,there were 36 males and 33 females.The average age was (49.3±12.9) years.The common symptom were hemotochezia,abdominal pain,constipation,diarrhoea and abdominal distension.There were 55 cases with lesions from the anus less than 8 cm and in other patients,lesions from the anus were all more than 8 cm.66 cases were typical carcinoid,3 cases were atypical carcinoid.40 cases underwent the immunohistochemical staining.The common markers for immunohistochemical staining were Syn,CgA and NSE,the positive percentage were 90％ (36/40),75％ (30/40) and 82.5％(33/40) respectively.A total of 24 patients received endoscopic therapy,44 patients had surgery,1 patient who refused surgery received only life support and symptomatic treatment.Conclusion No specific clinical symptoms of rectum carcinoid,and most were typical carcinoid.Lesions confined to mucosa and submucosa could be considered the endoscopic therapy.
