Objective To investigate the application value of recombinant human growth hormone ( rhGH) in the treatment of severe burns .Methods 36 patients with severe burns were selected and randomly divided into the observation group and control group ,18 cases in each group .Both two groups used the same anti-infection therapy , nutritional support and surgical methods .The observation group received rhGH subcutaneous injection therapy , the control group used the same amount of daily injections of 0.9%sodium chloride.The levels of tumor necrosis factor-α( TNF-α) and interleukin 6 ( IL-6 ) , wound healing time , hospitalization time and other indicators were compared between the two groups.Results 7d,14d after treatment,the TNF-αand IL-6 levels of the two groups were (18.4 ± 3.3)ng/L vs (24.9 ±7.3)ng/L,(133.2 ±66.9)ng/L vs (271.4 ±88.9)ng/L,(15.4 ±3.2)ng/L vs (25.4 ± 4.9)ng/L,(90.9 ±20.8) ng/L vs (200.7 ±62.2) ng/L,the differences were significant between the two groups (t=3.74,4.75,4.02,4.69,all P<0.05).The healing time and hospital stay in the observation group were signifi-cantly shorter than those of the control group (t=3.75,3.86,4.75,4.64,all P<0.05).Conclusion rhGH therapy can significantly improve the wound healing of severe burn patients ,reduce hospitalization time,it has good clinical results.

Multiple sclerosis (MS) is a demyelinating autoimmune disease of the central nervous system. It mainly occurs in young and middle-aged people and has a high disability rate. The pathogenesis of MS has not been fully elucidated, with great genetic heterogeneity, diverse clinical phenotypes, lack of specific biomarkers, numerous and complicated research data, which bring great challenges to the diagnosis and treatment of MS. Artificial intelligence (AI), as the cutting-edge hotspot in the development of science and technology, is widely used in the medical field to assist in the diagnosis, treatment and prognosis of various diseases. Its infinite learning ability greatly promotes the management of MS. This article will review the application of AI in MS diagnosis and treatment.

ObjectiveTo discuss the clinical characteristic and perioperative management of colonic obstruction caused by colonic carcinoma in elderly.MethodsThe clinical characteristic and perioperative management of 30 patients with colonic obstruction caused by colonic carcinoma from January 2000 to November 2010 were collected and analyzed retrospectively.Among 30 cases,11 cases were accepted emergency operation,19 cases were accepted limited operation.Resection and anastomosis at stage Ⅰ was in 26 cases (86.7％),shortcut surgery and simple fistulation was in 4 cases ( 13.5％ ).ResultsThe length of stay was 22-56 days.Postoperative complication including wound infection in 5 cases,wound liquescence in 3 cases,wound dehisce in 2 cases,anastomotic fistula in 2 cases,pulmonary infection in 3 cases.Two cases died during perioperative period.Conclusions Besides diagnosis as early as possible,appropriate perioperative management should be taken to the elderly patients,including reasonable operative time and surgical approaches and these are the keys to improve clinical curative effect.

Objective To investigate the feasibility of fast-track surgery in colorectal surgery.Methods Eighty consecutive patients with colorectal cancer admitted for colorectal surgery were divided into two groups by random digits table with 40 cases each. Group A was treated with the new concept of fasttrack surgery and group B was treated with the traditional methods of operation. The time of postoperative bowel venting and defecation,hospital stay time, the rate of complication, the rate of readmission and the total cost during hospitalization were compared. Results The time of postoperative bowel venting and defecation,hospital stay time were shorter in group A [(2.7 ± 0.9), (2.9 ± 0.1 ), (5.8 ± 1.0) d,respectively]than those in group B [( 3.9 ± 0.5 ), (4.2 ± 0.3 ), ( 8.3 ± 1.2) d, respectively] and the rate of complication and the total cost during hospitalization in group A [7.5%(3/40), ( 1.83 ± 0.22) ten thousand yuan] were lower than those in group B[27.5%(11/40), (2.35 ± 0.36) ten thousand yuan](P＜ 0.05). Conclusion The new concept of fast-track surgery can accelerate recovery after colorectal resection,reduce the rate of overall complications and total cost during hospitalization.

OBJECTIVE: Increasing of adhesion between leukemia cells and endothelial cells during all-trans retinoic acid (ATRA) treatment plays an important role in retinoic acid syndrome. This work observed the effects of tripterine on this ATRA-caused increasing in adhesion. METHODS: The effects of tripterine on ATRA-induced expressions of adhesive molecules in acute promyelocytic leukemia cell line NB4 and human umbilical vascular endothelial cells (HUVEC) were detected by flow cytometry. The effects of tripterine on adhesion between ATRA-treated NB4 and HUVEC were determined by adhesive assays. RESULTS: ATRA caused remarkable elevation of intercellular adhesion molecule-1 (ICAM-1) in NB4 cells, which could be significantly reduced by tripterine (P<0.01). The expressions of E-selectin, vascular cell adhesion molecule-1 (VCAM-1) and ICAM-1 in HUVEC were elevated by conditioned medium from ATRA-induced NB4 (ATRA-NB4-CM) (P<0.01), and inhibited by tripterine with inhibition rates being 25.3%, 42.4% and 61.0% respectively. ATRA increased the adhesion between NB4 and HUVEC, which was reversed completely by tripterine. CONCLUSION: Tripterine can inhibit ATRA-caused adhesion between leukemia cells and endothelial cells, and it might be a potential agent for treating retinoic acid syndrome.

Objective To discuss the efficacy and safety of covered Cheatham-Platinum stent (CCPS) implantation in treating coarctation of the aorta (CoA).Methods The clinical data of 11 patients with CoA who had received CCPS implantation were retrospectively analyzed.Results Successful implantation of single CCPS was accomplished in all 11 patients.After the implantation,the diameter of coarctation site was immediately dilated from preoperative (4.76+0.89) mm to postoperative (12.86+0.90) mm (t=24.86,P＜0.001),and the average systolic blood pressure difference across the coarctation was immediately reduced from preoperative (38.55+10.02) mmHg to postoperative (9.82+6.60) mmHg,the difference was statistically significant (t=10.8,P＜0.001).The patients were followed up for 3-79 months,with a mean of (31.91±27.58) months.The clinical symptoms were relieved in all patients and the activity tolerance was obviously improved.No complications such as endoleak,acute injury of aortic wall,re-coarctation or re-stenosis,vascular injury of puncture site,or death occurred in all patients.Conclusion For the treatment of CoA,implantation of CCPS has excellent short-term and mid-term effect,meanwhile,this technique can effectively avoid complications such as aortic wall iniurv.(J Intervent Radiol.2017.26:211-214)

Objective To examine the prevalence of depressive symptoms and related factors among HIV-positive men who have sex with men (MSM) in Shanghai.Methods All of the HIV-positive MSM were enrolled to participate in a cross-sectional study with questionnaire-based interview during Nov.,2014 to Nov.,2015.Depression was measured with a 12-item version of the Center for Epidemiological Studies Depression Scale (CES-D),where a score of 9 had been recommended as the cutoff score to indicate possible depressive symptoms.Results A total of 505 participants were recruited with a median age of 30.Among them,the majority were aged 21-44 (77.2％),non-local resident (64.6％),unmarried (73.1 ％) and university graduate or above (62.1 ％).Depressive symptoms were detected from 235 MSM and the prevalence of depression was 46.5 ％.Multiple logistic regression analysis showed that MSM who were non-local residents (OR =1.66,95 ％ CI:1.01-2.49)and had more than one male sex partner in the past year (OR=2.21,95％ CI:1.43-3.41) were more likely to have depressive symptoms compared with local residents and had only one male sex partner or less.On the contrary,compared with the education level of junior middle school or below and having no long-term partners,those who were senior high school educated (OR=0.39,95％ CI:0.21-0.74) and had homosexual behavior with main long-term partners without condoms (OR =0.38,95 ％ CI:0.17-0.85) had lower risk to be depressive.Conelusions The prevalence of depressive symptoms among HIV-infected MSM is high.Residence,education level,homosexual behavior with main long-term partner and number of male sex partner are significantly associated with depressive symptoms,suggesting psychological interventions should be further explored and studied.

Objective:To study the physical activity level and its influence factors among residents in one suburb of Beijing,so as to provide specific interventions for different people in different circum-stances and to provide reference for health relevant policy-making in the future.Methods:In the study, 7 31 9 subjects aged 1 8 years or above were involved.The self-designed questionnaires based on Health Belief Model (HBM)had acceptable validity and reliability.The physical activity levels were calculated to classify sufficient or insufficient amount by a thousand-step equivalent greater than or equal to 6 or 1 0. Multiple variable Logistic regression was used to explore the influence factors of the physical activity among the residents.Results:The residents’median amount of physical activity in the suburb district of Beijing were 9.1 thousand-step equivalent with quartile of (3.8,20.4).The percentages of the thou-sand-step equivalent greater than or equal to 6 or 1 0 were 63.7% and 47.7%,respectively.The median amounts of physical activity from work or household chores,transportation and recreation physical activi-ties were 4.0,1 .0,0.0 and the components of the total amount of physical activity from those were 61 .7%,1 8.3% and 20.1 %,respectively.There were 8.6% residents whose life did notinvolve moder-ate or vigorous intensity activities.By using factor analysis,five factors were extracted from the scale based on the HBM;These factors together contributed to 63.7% of the sum of the squared loadings.The differences of physical activity levels on education level,age,gender,self-efficacy,cues,subjective and objective barriers were statistically significant (P <0.05).Those who were female,with older age,lower education level,higher self-efficacy,fewer cues,fewer subjective and objective barriers preferred to do more physical activities.Conclusion:The physical activity levels among the residents in the suburb dis-trict of Beijing are moderate and high,and most amount of physical activities from work or household chores.Those who are male and whose ages are from 1 8 to 29 years and whose education levels are of university or above should be focused on intervention.Specific interventions should be developed for dif-ferent people in different situations;More attention should be paid to improve the residents’self-efficacy and reduce the subjective and objective barriers of physical activity,and we also should actively advocate people to have more leisure exercise so as to improve the physical activity level among all residents.

In China, the treatment of AIDS With Chinese herbal medicine compound has been widely studied and practiced. Clinical Studies showed that the treatment of AIDS with Chinese medicine can significantly relieve AIDS patients' clinical symptoms, improve life quality with rising immunity and alleviate toxic and side effects in antiviral drug. This study took 28 Clinical Studies on the treatment of AIDS with Chinese herbal medicine compound published in Chinese periodicals as the research object, and designed Tree Analysis Algorithm was used to analyze prescription compatibility in the treatment of AIDS with Chinese herbal medicine compound. Results of data analysis revealed that clinical therapy on AIDS could be classified into three types: predominent de-toxication, predominent supplementing Qi, and simultaneous de-toxication and supplementing Qi due to different understanding the pathogenesis of excessive evil and deficient essence-qi. But in practical medication, there has not formed a reasonable and effective combination or basic prescription up to now, except that Astragalus was wildly used.
