Objective: To investigate the effect of F.nucleatum(Fn) and P. gingivalis(Pg) on soluble intercellular adhesion molecule-1(sICAM-1) in peri-implant sulcular fluid(PISF).Methods: PCR was used to detect microorganism samples from PISF. According to detection of Fn and Pg, 51 titanium implants in 32 partly edentulous patients were divided into 3 groups. Clinical parameters included PD, mPLI and sICAM-1. Periopaper strips were used to collect PISF and an ELISA technique was applied to measure the levels of sICAM-1. Results: PD was significantly greater in the patients with Pg and/or Fn than that in those without Pg or Fn (P

Objective To evaluate the clinical feasibility of grading of ureteral stricture in renal allograft.Methods The clinical data of 9 case of ureteral stricture after renal transplantion from February 2015 to September 2015 were retrospectively analyzed and relative articles were reviewed to evaluate the significance of ureteral stricture grading.The diagnosis of ureteral stenosis was made by serum creatinine elevation,ultrasound of allograft kidneys and presence of stricture on a pyelogram.Grade 1 ureteral stenosis was defined as graft function deterioration with presence of hydronephrosis on ultrasound,but no obvious stricture identified on a pyelogranm.Grade 2 was defined as serum creatinine elevation,presence of hydronephrosis on ultrasound,and a focal (<1 cm) distal ureteral stricture at the ureteral anastomotic site on a pyelogram.Grade 3 was defined as serum creatinine elevation,hydronephrosis on ultrasound,and a long segment (>1 cm) distal ureteral stricture extending to proximal ureter or pelvis on pyelogram.Results One case,6 cases and 2 cases were classified to grade 1,2 (stricture length <1 cm) and 3 (>1 cm),respectively.One case of grade 1,6 cases of grade 2 and 1 case of grade 3 were successfully dilated by balloon dilation catheter and endoureterotomy.One case of grade 3 was converted to open reconstructive surgery.Surgery success rate of grade 1 and 2 was 100% (7/7) and 100% (6/6) 6 and 9 months after surgery,respectively.Ureteral stenosis did not recur in one case of grade 1 and 6 cases of grade 2 during a follow-up period of 12 months after surgery.However,one case of grade 3 reoccurred 6 months after surgery,and reoperation was performed and there was no recurrence up to now (10 months).Conclusion Wuzhi tablet acted as an effective agent that makes rifampicin containing anti-tuberculosis chemotherapy possible and safe by stabilizing blood concentration of tacrolimus in post-renal transplant tuberculosis patients,which also reduced the dosage of tacrolimus as well as the risk of acute rejection greatly.

OBJECTIVEThrough the establishment of mouse' ovalbumin- sensitized asthmatic model and the observation of the 8-Isoprostane of plasm, to evaluate the therapeutic effects of arsenolite on asthmatic mice.
METHODForty-two healthy Kunming male mice were randomly divided into control group and experience groups, the latter were treated with dexamethasone, arsenolite. Lung function were tested, 8-isoprostane of plasm and WBC of BALF were measured.
RESULTLung function improved after treating with dexamethasone or arsenolite. The WBC of asthmatic mice were significantly higher than those in control group, and decreased after treating with dexamethasone or arsenolite; 8-Isoprostane of plasm in asthmatic mice was higher than that of control group, and decreased after treating with dexamethasone or arsenolite.
CONCLUSIONThere is oxidant stress status in asthmatic mice. Arsenolite could lighten airway obstruction, reduce airway high response and redress oxidant stress status in asthmatic mice.

OBJECTIVETaking Chinese compound medicine Yuchangning as a research model, prepared the pH and time dependent Yuchangning tablets for colon-specific delivery (PT-YT-CSD), and evaluated the releasing property in vitro.
METHODThe coating prescription is filtered by the release extent of matrine and oxymatrine in vitro and the wicking rate of the tablet, which including the category and proportion of film forming agent and porogen, the sort and dosage of fluidizing agent, the increment of weight after coating and so on. The releasing property of the preparation is evaluated by the dissolution tests in vitro through measuring the content of matrine and oxymatrine content.
RESULTThe preparation method of the PYTCSD: After prepared plain tablets, the 95% alcoholic solution of EC and Eudragit II are mixed in a 7:3 EC: Eudragit II ratio and then added in DEP up to 10% of the coating amount, reduced the alcohol concentration to 4% by diluting with ethonal. Tablet was coated by the alcohol solution and the weight of the plain tablet was increased by 3%. The dissolution tests in vitro indicated that matrine and oxymatrine were not dissolved in the simulated gastric juice after 2 h. The accumulative quantities of matrine and oxymatrine were less than 10% in the simulated intestinal juice after 4 h. The quantities of matrine and oxymatrine are 75.7% and 76.8% in the simulated colon juice after 1 h.
CONCLUSIONThe PYTCSD was prepared and the preparation could fulfil the aim of delivering in the specific colon in vitro.

OBJECTIVETo detect the level and dynamic change of severe acute respiratory syndrome (SARS)-coronavirus-specific IgG antibody in conavalescent SARS patients, and to provide information for prevention and vaccine development.
METHODSIgG antibody against coronavirus was detected by ELISA in the blood of 311 convalescent SARS patients for every 2 - 4 weeks. Stata 7.0 statistics software was used to analyse the results.
RESULTSIgG antibody was detected positive on each testing of all the convalescent patients and its peak appeared 35 days after recovery. IgG antibody level showed a 35.8% decrease within one year.
CONCLUSIONData showed that all the SARS convalescent patients had generated high level of specific IgG antibody against coronavirus in the early stage of recovery, but the antibody level declined along with the progress of convalescence, suggesting that the detection of the IgG antibody should go on until it disappeared.

OBJECTIVETo evaluate the effect of ossicular reconstruction with partial ossicular replacement prosthesis (PORP) in patients with tympanosclerosis.
METHODSThe data of 28 cases of tympanosclerosis treated between 1992 and 2006 were reviewed. Of the 28 patients, 14 (14 ears) underwent ossicular reconstruction with PORP and 14 (14 ears) had ossicular mobilization, and all the patients were followed-up for 3-24 months.
RESULTSSignificant improvement was found in postoperative speech frequency (500, 1000, 2000 Hz) pure tone average (PTA) and air-bone gap (ABG) closure after in the operation the two groups. Ossicular reconstruction using PORP resulted in statistically better ABG closure and PTA (P<0.05).
CONCLUSIONIn ossicular attic fixation, ossicular reconstruction using PORP can yield better results than mobilization of the major ossicles in patients with tympanosclerosis.

OBJECTIVETo observe osteoclasts on the resorbing surface of human deciduous teeth.
METHODSAfter fixing the collected deciduous teeth, we prepared the tooth slices without decalcification, treated them with HE and TRAP dyestuff, and observed the osteoclasts under light and scanning electron microscope.
RESULTSThere were large quantity of various forms of overlapping and huge osteoclasts with many nuclei and silk-like protuberances on the resorbing surface of deciduous teeth. The multinucleated osteoclasts align on the surface of coarse dentin.
CONCLUSIONOn the resorbing surface of human deciduous teeth there are large amount of osteoclasts which can be used as a source of studying human osteoclast.
