The aim of this work was to investigate guar gum/ethylcellulose mix coated pellets for potential colon-specific drug delivery. The coated pellets, containing 5-fluorouracil as a model drug, were prepared in a fluidized bed coater by spraying the aqueous/ethanol dispersion mixture of guar gum and ethylcellulose. The lag time of drug release and release rate were adjustable by changing the ratio of guar gum to ethylcellulose and coat weight gain. In order to find the optimal coating formulation that was able to achieve drug targeting to the colon, the effect of two independent variables (the ratio of guar gum to ethylcellulose and the coat weight gain) on drug release characteristics was studied using 3×4 factorial design and response surface methodology. Results indicated that drug release rate decreased as the proportion of ethylcellulose in the hybrid coat and the coat weight gain increased. When the ratio of guar gum to ethylcellulose was kept in the range of 0.2 to 0.7, and the coat weight gain in the range of 250% to 500%, the coated pellets can keep intact for about 5 h in upper gastrointestine and achieve colon-specific drug delivery. The pellets prepared under optimal conditions resulted in delayed-release sigmoidal patterns with T5% (time for 5% drug release) of 5.1-7.8 h and T90% (time for 90% drug release) of 9.8-16.3 h. Further more, drug release was accelerated and T90% of the optimum formulation pellets decreased to 9.0-14.5 h in pH 6.5 phosphate buffer with hydrolase. It is concluded that mixed coating of guar gum and ethylcellulose is able to provide protection of the drug load in the upper gastrointestinal tract, while allowing enzymatic breakdown of the hybrid coat to release the drug load in the colon.

In this article we analyzed the current development of moxibustion treating rheumatoid arthritis from the usefulness, advancement, synergistic effect as well as the variance between different kind of moxibustion. We concluded that moxibustion was an effective intervention for treating RA, and the methods used in moxibustion were searched in clinic. But the clinical tralls has a long way to go, we should pay more attention to the critical issues while in the use of moxibustion.

Biotechnology supremacy is a newly-advanced power theory. It is a superior dominance of military biotechnological application based on the microcosm of life structure within a certain period of time. The advancement of biotechnology supremacy and modern biotechnology has created the concept of bio-micro-frontier, which involves information and defense resources of all living ultra-micro-organisms with national and regional characteristics. Being feasible both in theory and practice, the implementation of bio-micro-frontier system is strategically important. This article explores the implementation of bio-micro-frontier in terms of strategy and tactics, which will add a unique dimension to future military transformation and active defense.

Objective To investigate the clinical significance of serum omentin-1 levels in obesity and essential hypertension patients and its related influencing factors. Methods One hundred and thirty patients with obesity admitted to the Cadre Health Care Department of Navy General Hospital from Jun. 2011 to Dec. 2013 were enrolled in this study. According to the blood pressure,130 obesity patients were divided into simple obesity group( n=64 )and obesity hypertension group( n=66 ). Sixty non obesity patients with normal blood pressure were enrolled as control group. Serum omentin-1 levels were assessed by enzyme linked immunosorbent assay ( ELISA). Association between omentin-1 and biochemical parameters( including systolic blood pressure( SBP), diastolic blood pressure(DBP),body mass index(BMI),waist hip ratio(WHR),fasting blood glucose(FBG), triglyceride(TG),total cholesterol(TC),low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol( HDL-C),fasting insulin( FINS),insulin resistance index( HOMA-IR)and high sensitive C reactive protein(hs-CRP))were analyzed. Results Serum omentin-1 levels in control group was(26. 7 ± 5. 1)μg/L, significantly higher than that in simple obesity group and obesity hypertension group((22. 1 ± 3. 2)μg/L,(18. 3 ± 3. 4)μg/L;F=33. 7,P﹤0. 01),and serum omentin-1 levels in obesity hypertension group was significantly lower than that in simple obesity group( t =21. 5,P ﹤0. 05). Pearson correlation analysis showed that serum omentin-1 negatively correlated with BMI,WHR,SBP and HOMA-IR( r = - 0. 447,- 0. 340,- 0. 350,-0. 397;P﹤0. 01). There were no significant relations between omentin-1 and age,DBP,FBG,FBG,TG,TC, LDL-C,HDL-C,FINS and hs-CRP( P ﹥0. 05 ). Multiple stepwise regression analysis showed that HOMA-IR, BMI and SBP were independent influencing factors of serum Omentin-1. Conclusion The serum omentin-1 level decreases in the obesity hypertension patients. Omentin-1 is negatively correlated with BMI,SBP,and HOMA-IR, which may contribute to the underlying pathophysiology of obesity and essential hypertension.

Objective To investigate the causes,diagnosis,treatment of the difficult postoperative decannulation resulting from tracheotomy between children and adults and the method of improving the rate of successful decannulation.Methods Clinical data of 56 cases with difficult decannulation after tracheotomy were analysed retrospectively,all the patients were admitted in our hospital between Jan 1990 and Oct 2006.All the patients were separated into two groups,children group including 24 cases of 14 months ～ 14 years old,adult group including 32 cases of age ranging 15 ～ 48 years old.The postoperative time after tracheotomy were 6 month ～ 1.5 year and 6 month ～ 2 year respectively.Results There were differences of the etiology,diagnostic choice and the clinical manifestation in the treatment of the diffficult decannulation after tracheotomy between children and adults.Children with difficult decannulation after tracheotomy occurred mainly in laryngitis and airway foreign body airway caused by obstruction retrieved after tracheotomy (14/24,58.33 ％),followed by the emergency tracheotomy,such as head and neck trauma (7/24,29.17％).Adults with difficult decannulation after tracheotomy mainly occurred in the throat caused by traumatic lesions of the larynx (including malformations,subglottic stenosis of larynx or vocal cord paralysis) (23/32,71.88％).The average block time in children with anti-inflammatory treatment was significantly lower than that in without anti-inflammatory therapy (6.2 d vs 10.1 d,t =4.26,P ＜ 0.01).However,there was no significant difference in the average block time in adults with anti-inflammatory and without anti-inflammatory treatment (t =1.63,P ＞ 0.05).In the course of treatment,rates of children consciously breathing difficulties (21/21,100％) was also significantly higher than the adult group (13/28,46.43％).Conclusion Children less than 3 years old should avoid tracheotomy.There is no definite relation between the successful treatment in the difficult decannulation and the age of the patients over 3 years old.The first failure treatment in children may be related with the local inflammation.When in treatment,doctors should observe the characteristics of respiratory difficulties,take attention to the influence of children psychological factors to the treatment.Children should be treated in the non-traumatic examination methods.

Objective To study the role of lipase in inflammation in patients with acute pancreatitis.Methods Acute pancreatitis patients (n =200) were enrolled in the study.The patients were examined by computerized tomography and the severity of AP is determined by Blathazat Score.We assess the muhivariate-adjusted association of amylase and lipase with inflammatory markers of AP.We identified that lipase was more specifically correlated with AP progression than amylase,lactate dehydrogenase and creatitine kinase.Results We demonstrated that in AP patients,a doubling of lipase excretion was associated with 6.8％ increase of white blood cells (95％ CI,3.06％-10.5％,P ＜ 0.01),10.3％ (95％ CI,5.7％-14.9％,P ＜ 0.01) increase of neutrophil number but 14.8％ (95％ CI,2.3％-27.3％,P ＜0.05) decrease of lymphocytes in the blood,respectively.By contrast,amylase has no association with these cells.Both amylase and lipase had no relationship with triglyceride level in AP patients.Conclusions Lipase serves as an indicator for the severity and treatment of AP.

OBJECTIVETo study clinical effects of short-segment fixation and injured vertebra bone grafting through injured pedicle for the treatment of thoracolumbar burst fractures under MAST Quadrant retractor via a paraspinal muscle approach.

METHODSThe data of 42 patients with thoracolumbar burst fractures treated from June 2009 to September 2012 were reviewed. There were 19 males and 23 females, with an average age of (55.2±11.9) years old. The mean injury time was (5.8±4.3) days. Fracture segments included T10 in 3 cases, T11 in 6 cases, T12 in 13 cases, L1 in 9 cases, L2 in 7 cases, and L3 in 4 cases. According to Denis classification, 9 patients were type A, 21 patients were type B, 5 patiens were type C, 5 patients were type D, and 2 patients were type E. All the patients were treated with short-segment pedicle screw-rod system fixation under MAST Quadrant via the paraspinal muscle approach. The operative time, blood loss, complications and the height of vertebra, kyphosis Cobb angle, VAS scores, JOA scores were measured before and after treatment.

RESULTSAfter treatment, the vertebral height and kyphosis Cobb angle were restored. Compared with preoperative results, postoperative vertebral height and kyphosis Cobb angle, VAS scores and JOA scores were all improved. But there was no statistically significance in vertebral height, kyphosis Cobb angle between postoperative at 1 week and 1 year.

CONCLUSIONInternal fixation combined with injured vertebra bone grafting through the injured pedicle for the treatment of thoracolumbar burst fractures via the paraspinal intermuscular approach under MAST Quadrant is a safe, minimally invasive, effective and satisfactory method.
