Objective To explore a good of treating posttraumatic deviated nose. Methods Clinical data of 136 patients with posttraumatic deviated nose were analyzed.Closed nasal bone replacement was employed in 34 patients with the disease history of 20-30 days,while open rhino- plasty approach was employed in 102 patients with the disease history over 6 months to correct their postt- raumatic deviated nose,and straightening the septum and ectomizing the inferior turbinate were done if necessary.Results The follow-up was over one year.In the 34 patients with the disease history of 20- 30 days,the outcome was excellent in 28 cases and good in 6.In the 102 patients with the disease history over 6 months,the outcome was excellent in 81 cases and good in 21.The deformity of nose was corrected satisfactorily.Normal nasal shape and good ventilation were obtained.Conclusion Posttraumatic devi- ated nose deformities are often caused by delayed and inaccurate treatment.Closed nasal bone replace- ment can be employed for the patients with trauma history less than one month,and open rhinoplasty ap- proach and straightening the septum and restoration of the nasal shape are employed for other patients.In this way good results can be obtained.

Objective To investigate the expression level of peripheral blood neutrophil CD64 in Kawasaki disease (KD),and explore its clinical significance.Methods Fifty-four patients with KD were divided into 2 groups [13 patients with coronary artery lesions(CAL) and 41 patients without CAL],and 30 age-matched patients with sepsis and 10 healthy children were studied.The levels of peripheral blood neutrophil CD64 was measured by flow cytometry.Results Before treatment,the levels of C D64 in children with KD(7.02 ± 3.21)and sepsis (11.25 ± 5.14) were significantly higher than the healthy children (2.45 ± 0.52),and the level of CD64 in the KD group was significantly lower than that in sepsis group(P ＜ 0.01).CD64 index were significantly elevated in the 2 groups of KD patients before treatment (CAL group:5.74 ± 3.09 ; without CAL:7.43-± 3.17).There was no significant difference in the CD64 level between KD patients with CAL and without CAL.CD64 index in the 2 groups of KD patients after treatment (CAL group:2.56 ± 0.73 ; without CAL:2.63-± 0.69) were significantly lower than those before treatment (all P ＜ 0.01).Conclusions The expression of peripheral blood neutrophil CD64 in KD is significantly elevated.The degree of elevation in CD64 possibly has clinical meaning in differentiating KD from sepsis,and it can be a sensitive factor of disease outcome.

Objective: To explore the relationship between ABO blood group and acute non-ST-segment elevation myocardial infarction (NSTEMI) occurrence. Methods: Our research included 2 groups: NSTEMI group, 1039 relevant patients treated in Anzhen hospital from 2013-01 to 2014-12 were retrospectively enrolled; Control group, 1039 subjects with normal coronary artery which was confirmed by coronary angiography. The Baseline condition including age, previous disease history and ABO blood group was studied. Logistic regression model was used to conduct single and multivariate analysis. Results: In NSTEMI group and Control group, blood type A was 287/1039 (27.6％) vs 259 (24.9％), type B was 345 (33.3％) vs 356 (34.3％), type AB was 102 (9.8％) vs 114 (11.0％) and type O was 305 (29.4％) vs 310 (29.8％), ABO blood group distribution for A and non-A, B and non-B, AB and non-AB blood group, O and non-O had no statistic meaning between 2 groups, P>0.05. Logistic regression analysis indicated that with adjusted risk factors of MI such as age, gender, hypertension, diabetes, hyperlipemia, cerebrovascular disease and smoking, the patients with blood types A, B and AB had the similar risk for NSTEMI occurrence than type O patients; there was no relationship between ABO blood group and NSTEMI occurrence. Conclusion: ABO blood group had no relationship to NSTEMI occurrence.

Objective To investigate the prevalence and distributing feature of overweight and obesity in Han, Uygur and Hazakh population in adults from Xinjiang. Methods Four-stage selected random samples with maternal age at 35 or over were used to analyze the prevalence and distributing feature of self-reported congestive heart failure in different nationalities, age, sex. The sampled adult population were collected from 6 localities(Urumqi, Kelamayi, Fukang, the Turfan Basin locality, Hetian locality, Yili Hazakh autonomous prefecture), 23 municipalities and 7 locality and 5 autonomous counties in Xinjiang. Results 16 460 people were surveyed. The prevalence rates of overweight and obesity were 36.1% and 26.9% in Han, Uygur and Hazakh population in Xinjiang,respectively from February, 2007. The prevalence rates of overweight and obesity were 41.4% and18.4% in Han population, 34.9% and 28.9% in Uygur population, but 32.8% and 40.1% in Hazakh population. The prevalence rate of overweight and obesity was higher in males(x2= 135.00, P＜0.05).The prevalence rates of overweight and obesity were different between different ethnic groups(x2=338.232, P＜0.05). The prevalence of overweight was highest in Han population, with the highest seen in Hazakh population. The prevalence rates of overweight and obesity were increasing with age (x2=246.80,P＜0.05). The overweight rate in 45-54 year olds and the obesity rate in 55-64 year olds reached their peak values. Results from logistic regression model analyses indicated that the prevalence of overweight and obesity in Xinjiang were statistically associated with age, educational level, jobs, smoking and alcohol consumption. Conclusion The prevalence rates of overweight and obesity were much higher in the population of Xinjiang but different among ethnicities. The prevalence of overweight was the highest in Han male population and the rate of obesity in Hazakh male population was the highest.

Objective:To investigate the efficacy of Baxian Xiaoyaotang （BXT） in treating ankylosis of wind-cold-dampness obstruction syndrome after acute Achilles tendon rupture surgery and its effects on transforming growth factor-β₁ （TGF-β₁）， insulin-like growth factor-1 （IGF-1）， and epidermal growth factor （EGF）. Method:According to the visiting sequence， 66 patients with fresh closed Achilles tendon rupture were included and randomly divided into a treatment group （n=33） and a control group （n=33）. Patients in both groups underwent surgical repair， followed by immobilization in long-leg brace， which was then replaced by the boot brace in the fourth week， with the plantar-flexion angle adjusted correspondingly. Six weeks later， the brace was removed for accelerated functional rehabilitation training. On this basis， patients in the treatment group were further instructed to fumigate and wash the affected Achilles tendon with BXT， twice a day， for 45 d. The Leppilahti Achilles tendon performance scores and American Orthopaedic Foot and Ankle Society （AOFAS） ankle-hindfoot scores between the two groups were compared at the time of brace removal and the third， sixth， and twelfth months after surgery. The strength of triceps surae on the affected side was evaluated at the last follow-up visit. The serum TGF-β₁， IGF-1， and EGF levels were detected before and after treatment. The wind-cold-dampness obstruction syndrome scores， symptom scores， the changes in foot dorsiflexion angle， and the overall clinical efficacy were compared. Result:The changes in scores of patients receiving different treatment measures did not synchronize. After the removal of brace， the Leppilahti Achilles tendon performance score and AOFAS ankle-hindfoot score determined at three time points in the treatment group were higher than those in the control group （P<0.05）. At the last follow-up visit， the good-to-excellent rate of muscle strength in the treatment group was 93.94% （31/33）， higher than 72.73% （24/33） in the control group （χ²=0.031，P<0.05）， implying that the strength of triceps surae in the treatment group was better recovered. After treatment， the serum TGF-β₁， IGF-1， and EGF levels in both groups were increased in contrast to those before treatment （P<0.05）， and these levels in the treatment group were all higher than those in the control group （P<0.05）. The foot dorsiflexion angle and the wind-cold-dampness obstruction syndrome score in the treatment group were superior to those in the control group （P<0.05）. The overall response rate of the treatment group was 90.91% （30/33）， higher than 75.76% （25/33） of the control group （χ²=6.981， P<0.05）. No adverse reactions occurred during the treatment. Conclusion:The external fumigation and washing with BXT alleviates both the clinical symptoms and traditional Chinese medicine （TCM） syndrome， improves the joint function score， triceps surae strength， and other indicators， elevates the serum TGF-β₁， IGF-1， and EGF levels， and enhances the strength and toughness of Achilles tendon of patients with ankylosis due to wind-cold-dampness obstruction after the acute Achilles tendon rupture surgery. Its clinical efficacy is better than that of functional rehabilitation training.

To study the biopharmaceutics characteristics of paris saponin VII (PSVII). The solubility of PSVII was evaluated by measurement of the equilibrium solubility in different solvents and media. The permeability of PSVII was evaluated by measuring the oil/water partition coefficient (lgP) and determining the apparent permeability coefficient (PC) on a mono-layer Caco-2 cell model. The effects of p-glycoprotein and multidrug resistance related protein 2 on PSVII transport in mono-layer Caco-2 cell model were further investigated. Finally, the small intestinal absorption of PSVII was investigated in rat. In solvents of different pH, the equilibrium solubility of PSVII was quite low, and the dose number of PSVII was larger than 1. The lgP of PSVII was less than 0. The apparent permeability coefficient [PC] of PSVII in mono-layer Caco-2 cell model was less than 14.96 × 10 cm·s, and the efflux ratio of PSVII in mono-layer Caco-2 cell model was less than 1. The transport rate of PSVII in mono-layer Caco-2 cell model was not affected by the inhibitors of p-glycoprotein and multidrug resistance related protein 2. After oral administration, PSVII could be detected in rat intestinal contents, but could not be detected in the small intestinal mucosa. PSVII showed low solubility and permeability, which would result in low oral bioavailability in clinic. PSVII belonged to Class IV compound in biopharmaceutics classification system.

Dental implants represent the majority of treatment strategies used to replace missing teeth. However, peri-implant diseases caused by disturbance in peri-implant microbiological balance are among the reasons for implant failure. Since the 1980s, peri-implant microorganisms have been a hot research topic in dental microbiology. The bacterial ecology between the disease and health largely differs, which directly or indirectly increases the risk of peri-implant diseases. Accordingly, the determination of the 'core microbiome' of peri-implantitis and peri-implant mucositis is a key point of recent research.

Titanium dental implants have wide clinical application due to their many advantages, including comfort, aesthetics, lack of damage to adjacent teeth, and significant clinical effects. However, the failure of osseointegration, bone resorption, and peri-implantitis limits their application. Physical-chemical and bioactive coatings on the surface of titanium implants could improve the successful rate of dental implants and meet the clinical application requirements. This paper reviews the characteristics of surface modification of titanium implants from the aspects of physics, chemistry, and biology. Results provide information for research and clinical application of dental implant materials.
