OBJECTIVETo compare the effect of three kinds of extraction model on high angle bimaxillary protrusion patients.
METHODSA total of 30 patients with Class I malocclusion and bimaxillary protrusion, aged 14-25 years old, were selected and divided into three groups. Four first premolars were extracted in the first group. The two maxillary first premolars and two mandibular first molars were extracted in the second group. The two maxillary first premolars and two mandibular first molars were extracted in the third group, and two additional micro-implants used as orthodontic anchorage in maxilla. Three groups were all treated with MBT appliance. Cephalometric analysis were carried out before and after treatment, and the results were analyzed with statistics.
RESULTS1) About the hard tissues, compared with the first group, there were statistically significant differences of N-Me, SGo/NMe, ANS-Me, FH/MP, SN/MP, and ODI in the second and the third group after treatment (P<0.01). 2) About the soft tissues, the teeth and the alveolar bone, compared with the first group, there were statistically significant differences of Pg-Pos, Li-SnPos, Si-LiPos, LL-E, L1-NB, L1/NB, U1/L1, L7-MP in the second and the third group after treatment (P<0.01). 3) All patients received consummate orthodontic treatment and obtained fine occlusion. Facial profiles were improved significantly after orthodontic treatment.
CONCLUSION1) After orthodontic treatment with mandibular first molars extraction, FH/MP, SN/MP, N-Me, ANS-Me, L1-NB and L1/NB decreased respectively, and soft tissue profiles were improved significantly. 2) Additional micro-implant used as orthodontic anchorage in maxilla significantly contributed to the maxillary incisor retraction and subsequent soft tissue change. 3) The first molars extraction and additional micro-implant used as orthodontic anchorage are efficient in improving the facial profiles for high angle bimaxillary protrusion patients.

OBJECTIVETo investigate the effect of Nifedipine on matrix metalloproteinase (MMP)-10 and MMP-13 expression in human periodontal ligament fibroblast (HPDLF) induced by mechanical strain in vitro.
METHODSHPDLF was divided into four groups at random by mechanical strain of elongation 0%, 8%, 12% and 16%. Each group was divided into four subgroups again by the concentration of Nifedipine 0, 10, 30, 50 microm. The cells were imposed to state mechanical strain 12 h after incubated with Nifedipine 1 h. And then immunohistochemical staining was used to investigate the expressions of MMP-10 and MMP-13 in intracytoplasm.
RESULTSIn 0% group, there was no significant difference of MMP-10 and MMP-13 expression in all subgroups (P>0.05). The expressions of MMP-10 and MMP-13 were high in group 8%, 12% and 16% without Nifedipine, and increasing significantly with elongation (P<0.001). The expressions of MMP-10 and MMP-13 decreased with dose increasing (P<0.001) in HPDLF after imposed to Nifidepine.
CONCLUSIONThe expressions of MMP-10 and MMP-13 induced by mechanical strain were inhibited by Nifedipine, which suggested calcium ions channels participate in expressions of MMP-10 and MMP-13 induced by loading.

A significant-source of allergens come from house dust that contain particles derived from arthropods, molds, and pet dander. This study evaluated mite and booklouse fauna from vacuumed dust samples in Beijing China (a temperate zone). Our survey was carried out in Beijing in the homes of mite allergic patients who visited our Allergy Department. In total, 38 homes were selected for the collection of dust samples by vacuuming, from December 2008 to January 2010. The flotation method was used to isolate mites from house dust. Permanent slides were prepared for mite specimens and mites were identified and counted under a microscope. In total, 1,798 separate mite and insect specimens were found in 345 dust samples taken from 38 homes. A total of 95 individual Dermatophagoides (D) siboney were detected in 35 dust samples from 19 homes (representing 5.3% of all mite and insect species found in house dust); in addition, this mite was found to co-exist with D. farinae (Hughes, 1961) in 33 dust samples. Our results demonstrated the presence D. siboney that co-existed with D. farinae in house dust in Beijing China (a temperate zone).

Objective To analyze the demand for non-occupational post-exposure prophylaxis (nPEP) services and related influencing factors among men who have sex with men (MSM) in Liuzhou City, Guangxi Province. Methods MSM was recruited in Liuzhou City, Guangxi Province. Face-to-face survey was used to collect demographic information, knowledge about AIDS, history of high-risk behavior, knowledge and demand for nPEP services. 2 test was used to analyze the differences of demand for nPEP services among MSM with different characteristics and different high-risk behaviors. Log-binomial regression model was used to analyze the influencing factors of demand for nPEP services. Prevalence ratio and 95% confidence interval were calculated. Results 31.1% of MSM population had heard of nPEP service, and 61.6% of them needed the service after being informed of nPEP about its protective effect. 58.6% of MSM would spend money to buy nPEP service after high-risk behavior. Logistic regression analysis showed that the education level was university degree or above (PR=2.743, 95% CI: 1.996-3.450), the perception of the local MSM AIDS epidemic was not serious or unknown (PR=0.211, 95% CI: 0.112-0.294), and the number of temporary sexual partners in half a year was 2 or more (PR=3.642, 95% CI: 2.223-4.842), these subjects above were influencing factors of nPEP service demanded for respondents. Conclusions MSM population in Liuzhou area of Guangxi have a certain need for nPEP service. We should implement nPEP service as soon as possible in accordance with local conditions, and strengthen the corresponding propaganda to reduce the harm of AIDS to MSM population.

Objective: To evaluate the effects of CYP2C19 genetic polymorphism on the plasma concentration of voriconazole in patients with hematological disease and the value of serial monitoring plasma concentrations in the treatment and prevention of invasive fungal disease (IFD). Methods: From January 2016 to December 2016, 65 hematological patients who received voriconazole intravenous administration for the treatment of invasive fungal disease were enrolled in this study. The population CYP2C19 polymorphism of voriconazole were performed using PCR-Pyrosequencing. The trough plasma concentrations of vriconazole (Ctrough) was detected by ultra performance liquid chromatography tandem mass spectrometry. Results: Based on the genotype analysis, 65 subjects were identified as extensive metabolizers' group (30 cases) and poor metabolizers' group (35 cases). The Ctrough of the 65 patients were detected for 169 times totally, and there was a significant difference of Ctrough values between the two groups [0.98(0.38-2.08) mg/L vs 2.19(1.53-4.27) mg/L, z=10.286, P<0.001]. The medium of Ctrough in 65 hematological patients were described. Lack of response to therapy was more frequent in patients with voriconazole levels <1.5 mg/L (50.0%) than in those with voriconazole levels >1.5 mg/L (20.5%) (P=0.052). And the risk of adverse events was more frequent in patients with voriconazole levels >5.5 mg/L (80.0%) than in those with voriconazole levels ≤5.5 mg/L (8.3%) (χ2=11.689, P=0.020). Conclusion: Patients with CYP2C19 wild-type phenotype are extensive metabolizers, their Ctrough of voriconazole are significantly lower than patients with CYP2C19 non-wild-type phenotype (poor metabolizers). Appropriate concentrations of vriconazole can improve the efficacy and safety during treatment.

OBJECTIVETo analyze the relationship between radiographic parameters and clinical outcomes of patients with distal radius fractures in elderly patients following conservative treatment, and find the important radiographic parameters with distal radius fractures in elderly patients.
METHODSFrom May 2012 to May 2015, a retrospective analysis was performed of 45 elderly patients with distal radius fractures treated by conservative treatment, which including 17 males and 28 females with an average age of 64.49 years old from 60 to 89 years old. The imaging parameters were measured and the clinical efficacy was evaluated. The imaging parameters on the standard wrist joint X-ray picture were measured including metacarpal angle, the radius height, the ulna variation, the ulnar angle, and so on. The clinical effect of wrist joint was evaluated by Dienst score standard. Multiple factor linear regression was used to analyze the relationship between the image parameters and the clinical efficacy.
RESULTSAll patients were followed up for 12 to 24 months with an average of 17.6 months. All fractures of the distal radius were healed. According to the Dienst evaluation, at the final follow-up the result was excellent in 27 cases, good in 10 cases, fair in 6 cases and poor in 2 cases. There was a significant correlation between the height of the radius, the angle of the palmar and the variation of the ulna and the function of the wrist joint in the imaging parameters. When the radius height more than 8.12 mm, the palmar angle more than -1.64 degree and the ulna variant less than 4.05 mm, the result of Dienst function was better.
CONCLUSIONSThe imaging parameters such as the radius height, the palmar angle and the ulna variation are related to the recovery of the clinical efficacy of the distal radius fractures in the elderly. The most important parameter is the radius height, which reminds the surgeon to pay special attention to the reduction of the radius fracture in the elderly.
