Papillary thyroid cancer (PTC) is the most common type in thyroid carcinomas.Recently,the prevalence and diagnostic rate of PTC has got significantly high with the general use of ultrasound.Nowadays,more and more studies have suggested that the coexistence of PTC and diabetes is common.They indicated that hyperglycemia would induce the deterioration of oxidative stress injury,chronic inflammation,insulin resistance,obesity,dyslipidemia,deficiency of vitamin D and dysimmunity.All of these may break the balance of oxidation and antioxidation and result in disordering signal pathway,accumulation of inflammatory cytokines,over activating of insulin and insulin-like growth factor-1,changing the metabolic pathways,which will promote the occurrence and progression of PTC.

Background Keratectasia after laser in situ keratomileusis (LASIK) is one of the serious complications which affect the vision.The measurement of cornea posterior elevation is an important way helping to find this change.Objective The aim of this study was to investigate the change of cornea posterior elevation after LASIK in myopic eyes with astigmatism and affecting factors.Methods A series case-observational study was adopted.One hundred and twenty-seven myopic eyes with astigmatism of 66 patients who received LASIK in 2008 May through 2010 January in Beijing Tongren Hospital were retrospectively analyzed to evaluate the change of cornea posterior elevation following the LASIK.The parameters related to cornea posterior elevation were measured and compared before and 3 months,6 months and 1 year after surgery,respectively,with Oculyzer anterial segment analysis system.Results The height values from posterior cornea highest point,the lowest point and central vertex central elevation zone were (12.20±3.39),(-19.02±7.38) and (1.05 ±3.25) μm respectively before LASIK and were (14.38±3.80),(-18.55±7.11),(2.83±4.81)μm in3 months and (13.99±3.38),(-17.57±6.54),(2.45±4.61) μm in 6 months after LASIK.They were (14.40±3.85),(-17.76±6.00),(2.16±5.00) μm in 1 year after surgery.Significant increases were found in the vertex height and central elevation after LASIK compared with before surgery(highest pointq=6.813,5.594,6.875,all at P＜0.001.central vertex:q=4.488,P=0.002;q =3.530,P=0.013 ;q =2.799,P =0.047).However,no significant difference was seen in various time points after LASIK (P＞0.05).A positive correlation was obtained between the height value of the posterior cornea central vertex with the spherical equivalent (SE),maximum cutting depth or cutting proportion 1 year after LASIK (r =0.295,0.297,0.295,all at P=0.001),and there was a negative correlation between it with residual stroma (r=-0.208,P=0.019).The intraocular pressure (IOP) measured with noncontact tonometry (NCT) was (14.24±3.33) mmHg before LASIK,and those of 3 months,6 months and 1 year were (8.42± 1.90),(8.61 ± 1.64) and (8.76± 1.64)mmHg after LASIK,showing a significant lowing in IOP after LASIK in comparison with before LASIK (q =29.851,28.317,26.337,all at P＜0.001).But no significant change was found in the different time points after LASIK (P＞0.05).There was significant difference in the IOP corrected by Ehlers after LASIK (P＞0.05).The IOP before LASIK had positive correlation with the central elevation of posterior cornea surface 1 year after LASIK(r=0.258,P =0.003).Conclusions The cornea posterior elevation increases slightly early stage after LASIK but retains stable level with lapse of time.The refraction diopter before LASIK is the main factor affecting the posterior corneal shape.To reduce the risk of corneal ectasia,more attention should be paid to the reserving of appropriate corneal residual stroma and smallest degree of eccentricity during the ablation procedure.

This study was designed to validate the correlation between integrated pharmacokinetic and therapeutic effects of alkaloids using bile processed Rhizoma Coptidis (BRC). Rats were divided into three groups: normal, disease model, model+BRC. Rats were induced to have an excessive heat syndrome. Rectal temperatures were collected at 0, 3, 6 and 9 h after single oral administration of the drugs. The plasma concentrations of three alkaloids were quantified at different times by UPLC-MS/MS after the administration of BRC. An approach of self-defined weighting coefficiency was created to the holistic pharmacokinetic profiles of alkaloids in BRC. The classified and integrated synthetic concentrations were obtained, and then the pharmacokinetic parameters of alkaloids were calculated from non-compartmental model analysis. The potential relationship between the integrated mean concentration of alkaloids and the antifebrile efficacy was investigated. The holistic t(max) of alkaloids was 1.11 h, the antifebrile effect of BRC at 3 h was improved over the model group. Double peaking appeared in the integrated blood concentration-time curve, the second t(max) of alkaloids was 4.82 h. The antifebrile effects of BRC at 3-6 h were significant, and the antifebrile effects at 6-9 h was decreased significantly. Dynamic variation of alkaloids of BRC in the body exhibited the similarity to the pattern of its antifebrile effect.

OBJECTIVEThis study aimed to investigate the duration of gingival healing after the stage II surgery of dental implantation for periodontitis patients and to provide clinical guidelines for implant restoration.

METHODSTwenty-nine periodontitis patients who had implantation surgery and achieved osseointegration were operated with stage II surgery (a total of 60 pieces of implants). The height of buccal gingival of each implant was measured twice after the stage II surgery. All implants were measured at the lowest point ofbuccal gingival after one week. The implants were randomly divided into four groups according to the schedule of the next test time: group one at one week from the initial test point, group two at two weeks, group three at three weeks, and group four at four weeks. Each group includes 15 pieces of implants. The amount of the buccal gingival change in each group between the second and first tests was determined, and the data were analyzed statistically.

RESULTSThe amount of gingival change of groups one, two, three, and four was (-0.25 +/- 0.66), (-0.04 +/- 0.52), (-0.70 +/- 0.77), and (-0.74 +/- 1.09) mm, respectively. No significant difference was observed between groups one and two in terms of the amount of gingival changes (P > 0.05). However, a significant difference was found between groups two and three (P < 0.05), and the amount of gingival recession was 0.66 mm. No significant difference was found between groups three and four (P > 0.05), and the gingival achieved stability.

CONCLUSIONThe gingival recession achieves stability at the fourth week (after 28 d) after stage II surgery. At this time, the implant can be restored, and the abutment can be selected according to the amount of gingival change of the periodontitis patient.
