Objective\ To study the early diagnosis and treatment of the fracture of posterior medial tubercle of the talus (PMTT).Methods\ Five cases of PMTT fractures had been definitely diagnosed by CT scan. Subtalar joint were involved in three cases, open reduction and internal fixation (ORIF) had been adopted in 2;and 1 had been treated conservatively because of the refusal to surgery by the patient. Plaster cast fixation and excision of fragment was done respectively in one case. Results\ Four out of five cases had been correctly diagnosed and one had been misdiagnosed in the first visit.The mean follow up was 24 months. Non union combined with tenderness and numbness of the sole of the foot was found in the misdiagnosed case after 6 months. Excision of the fragment was carried out for this case and a satisfactory result had been achieved. Three of the other four cases was treated operatively with a good result and one were treated conservatively with a poor result. Conclusion\ The PMTT fractures are rarely seen and often misdiagnosed. Early diagnosis and correct treatment is important to eliminate the nonunion or tarsal tunnel syndrome.

Objective To study the proliferation promoting effect on osteoblast cells induced by sodium orthovanadate and whether nitric oxide (NO) was involved in this process. Methods MTT assay was employed to determine cell proliferation and its inhibition. The level of NO was measured by enzyme reduction method. Results The MTT values of MC3T3-E1 cells under the 2.5,5.0,10.0 ?mol/L of sodium orthovanadate were 0.3380?0.0045, 0.3400?0.0141, 0.3840?0.0313 respectively, which were higher than in control group (0.2540?0.0167)(P

As a zinc finger protein with ubiquitin-modifying activity, A20 is highly expressed in most mammalian cell in response to stimuli of tumor necrosis factor (TNF), lnterleukin-1 (IL-1), lipopolysaccharide (LPS) and other factors. A20 has been found to play a crucial effect in control of the cell maturation, cytokine production and immunostimulatory potency of dendritic cells (DCs) via modulating down-regulation of NF-κB signaling transduction pathway. In this brief review, we descript the biological characteristics of A20 and the involvement of the A20 in the pathway of the immune responses toward to the DC cell maturation and immunostimulatory potency.

Objective To explore the association between the single-nucleotide polymorphism (SNP) rs3822086 site of the α-Synuclein(SNCA)gene and Parkinson's disease (PD) of Uygurs versus Hans in Xinjiang,and to compare the distribution difference of this polymorphic site between the Uygurs and Hans.Methods The rs3822086 polymorphism was determined by polymerase chainreaction restriction fragment length polymorphism (PCR-RFLP) in 237 patients with idiopathic Parkinson's disease (IPD,including 92 Uygurs and 145 Hans) and 247 health controls (including 103 Uygurs and 144 Hans).Results In the group aged ≥60 years,the T/T,C/T genotypes and T allele frequency were higher in PD group (196 cases) than in control group (196 cases) (25.5％ vs.20.9％,52.0％ vs.44.4％ and 51.5％ vs.43.1％),for genotype:P=0.027,allele:P=0.018.Between the Uygur versus Han nationality population,the T/T,C/T genotype and T allele frequency in the Uygurs were lower than in the Hans (15.4％ vs.30.4 ％,45.6％ vs.50.5％ and 38.2％ vs.55.7％),for genotype:P =0.000,allele:P =0.000.Conclusions The SNP rs3822086 site of SNCA gene may be a potential susceptibility site of IPD patients over the age of 60 years in Xinjiang,and rs3822086C/T + T/T is susceptible genotypes and rs3822086T is susceptible alleles.The distribution of rs3822086 polymorphism of SNCA might have a significant difference between the Xinjiang Uygur and Han populations.

Objective To evaluate the orthodontic effect of surgery on mixed dentition period class Ⅲ malocclusion and to investigate the effective therapeutic method of the skeletal class Ⅲ malocclusion.Methods A total of 20 patients aged 8.5 to 9.1 years with early mixed dentition class Ⅲ skeletal malocclusion.The treatment was divided into two phases.During the first phase,the entire stuffy group was treated with a bonded maxillary expansion and protraction.During the second phase,the entire study group received multiple loop edgewise arch wire (MEAW) treatment until an ideal occlusion relationship achieved.Comparison of the pre-and post-orthodontic treatment cephalometric radiographs had been done after maxillary protraction and MEAW were applied for patients.Results In the 20 patients after orthodontic treatment,Class Ⅲ skeletal facial profile was improved,the retraction of anterior teeth was obvious,and there were significant changes in dentition; the profile of soft tissue and satisfactory occlusion relationship were significantly improved,as compared with the changes between pre-treatment and post-treatment.Conclusions Skeletal Ⅲ malocclusion in early mixed dentition can be successfully treated.The results can be satisfied with improved class Ⅲ skeletal and molar relationship,high-angle and profile of soft tissue.

This study was aimed to explore the influence of extreme environment changes on the lung immune function in rats. Artificial climate system was used to simulate six extreme weathers, which were the sudden temperature increase (ZS), sudden temperature drop (ZJ), continuous high temperature (CG), continuous low temperature (CD), high temperature and high humidity (GWGS), normal temperature and high humidity (CWGS). And then, the method of enzyme-linked immunosorbent assay (ELISA) was adopted to detect bronchoalveolar lavage fluid (BALF) and related immune substances in lung tissues. The results showed there was significant difference of ZJ on IL-10 (P<0.05). There were significant differences of CG, CD, GWGS, and CWGS on IL-6, INF-γ and sIgA (P<0.05). Contents of the GWGS group and CWGS group were higher than that of the CG group and CD group. There was very significant difference on IL-10 in the CD group (P<0.01). It was concluded that the extreme environment changes had different influence on body’s immune. And different intervention factors cause the body’s immune factors to response accordingly.

Objective To investigate association between postural changes of blood pressure and carotid atherosclerosis in the elderly.Methods Standardized questionnaires,physical examination and biochemical blood tests were performed to acquire clinical characteristics of the participants.Presences of carotid plaques were identified by carotid ultrasound examination.Orthostatic hypotension (OH) and orthostatic hypertension (OHT) were defined according to the international consensus.Multivariable logistic regression analysis was performed to analyze the associations of carotid plaques with OH and OHT.Results 377 old people were finally included,of which 101 had OH and 33 had OHT.After full adjustment for possible confounders,old people with carotid plaques had significantly increased risk for OH as compared with those without carotid plaques (OR=2.27,95％ CI:1.32-3.90,P=0.003).Participants with bilateral carotid plaques were associated with significantly increased risk for OH (OR=3.45,95％CI:1.74 6.84,P=0.001),while the association between unilateral carotid plaques and OH was not significant (OR=1.71,95％ CI:0.88-3.32,P=0.112).No significant association was identified between carotid plaques (bilateral or unilateral) and OHT.Conclusions Presence of carotid plaques,particularly bilateral plaques,may be an independent risk factor for OH.
