Objective To explore the clinical features,diagnosis and treatment of serious pyogenic infection in deep neck. MethodsFrom January 2002 to April 2005,the clinical data of 22 patients hospitalized with serious pyogenic infection in deep neck were collected and retrospectively analysed. Results All the patients suffered unilaterally.Besides the symptoms of infection,dyspnea,pain in swallowing,limitation of mouth opening and progressive limitation of cervical activity were presented.Bacterial cultivation were performed in 14 patients and positive results were detected in six.Fourteen of all the 22 patients were cured with antibiotics,and abscess incision drainage was carried out in the other eight.Preoperative cervical PA-LAT X-ray photography and contrast-enhanced CT scanning were performed on one and seven patients,respectively,all of which indicated the formation of abscess.All the patients were cured except one who died of cerebral infarction and multiorgan dysfunction. Conclusion Imaging evaluation plays a significant role in the preoperative diagnosis and systemic treatment of serious pyogenic infection in deep neck.Bacterial cultivation provides reliable evidence for the etiopathogenisis and helps to make the effective treatment.

Facing the current situation of scientific literacy in vocational medical school, med-ical science literacy education has been penetrated into the teaching process of human functionology by measures of combining with research materials and clinical cases, increasing the proportion of ex-perimental teaching, stressing comprehensive practical projects and carrying out the ‘competitive learning’ to improve competency and occupation competitiveness of vocational medical students.

OBJECTIVE:To observe the effect of ulinastatin on the serum inflammatory cytokines of patients with ulcerative colitis. METHODS:Totally 60 patients with ulcerative colitis were randomly divided into observation group and test group,and an-other 20 healthy volunteers were selected as normal control group. Test group were received routine treatment,including nutrition support and maintaining water,electrolyte balance and 5-amino salicylic acid (5-ASA),etc. Patients in observation group were treated by ulinastatin 200 000 U by intravenous infusion based on the treatment of test group,q12h. 7 d were as a course for the pa-tients,and it lasted for 2 courses. The clinical data in healthy control group and other 2 groups was observed,including tumor ne-crosis factor-α(TNF-α),interleukin-1β(IL-1β),IL-8,C-reactive protein(CRP)levels,colon peroxidase activity(MPO),clinical activity index(CAI)scores and the incidence of adverse reactions before and after treatment. RESULTS:Before and after treatment, the TNF-α,IL-1β,IL-8,CRP and MPO in other 2 groups were significantly higher than health control group,with significant dif-ferences(P<0.05). After treatment,the TNF-α and IL-1β in 2 groups and the IL-8 and CRP levels in observation group were low than before,and the TNF-α,IL-8 and CRP levels in observation group were significantly lower than test group,with significant dif-ferences(P<0.05). There were no obvious adverse reactions during treatment. CONCLUSIONS:Based on the routine treatment, ulinastatin can effectively inhibit the expression of inflammatory cytokines of patients with ulcerative colitis,and relieve the inflam-mation and injury of colon,with good safety.

Promotion of outstanding people to head nurses is key to hospital nursing management.In view of the current shortcomings in the analysis of appraisal data and the interpretation of appraisal results,the analysis of means(ANOM)method is introduced to the process of hospital human resource management.The proposed method aims to solve the problem when the score differences between interviewers are great and the score differences between candidates are small.An example for head nurses' promotion appraisal in a hospital is offered to demonstrate that statistical tools can provide the decision support for hospital personnel selection.Finally,the application differences between ANOM and analysis of variance(ANOVA) in human resources appraisal are compared.

Objective To investigate the effect of miR-30a on human osteosarcoma cell 143B in migration,invasion andcellviability.Methods 143BcellswereinfectedortransfectedwithrecombinantadenovirusmiR-30a(Ad-miR30a) and miR-30a inhibitor respectively .Wound healing assay was performed to detect the cell healing ability ( P<0.05 ) .Cell migration and invasion ability were determined by Transwell assay ( P<0.05 ) .The cell viability was analyzed by MTT assay ( P<0.01 ) .Real-time quantitative PCR was performed to analyze the expression of RUNX2 mRNA level and confirmed the adenovirus miR-30a expressed in 143B cells.The expression of RUNX2 was analyzed by Western blot .miR-30a target to RUNX2 was verified by luciferase reported gene assay .Results The ability of migration and invasion was suppressed in osteosarcoma cell 143B by overexpression miR-30a,and the cell viability also decreased .After the endogenous miR-30 a being inhibited , the cell motility and invasion enhanced and the cell viability was promoted .The RUNX2 protein decreased after overexpression miR-30 a as compared with controlgroup.TheluciferaseactivityofRUNX2decreasedbyaddingmiR-30a.Conclusions 143Bcellmigration, invasion and viability were suppressed by miR-30a,and this process is potentially achieved via suppressing RUNX 2 protein expression .

Background Chinese dietary reference intakes for calcium are largely based on foreign studies.We undertook metaregression to estimate calcium requirements for Chinese adults derived from calcium balance data in Chinese adults.Methods We searched PubMed,Cochrane CENTRAL,and SinoMed from inception to March 5,2014,by using a structured search strategy.The bibliographies of any relevant papers and journals were also screened for potentially eligible studies.We extracted a standardized data set from studies in Chinese adults that reported calcium balance data.The relationship between calcium intake and output was examined by an individual participant data (IPD) and aggregate data (AD) meta-regression.Results We identified 11 metabolic studies in Chinese adults within 18-60 years of age.One hundred and forty-one IPD (n=35) expressed as mg/d,127 IPD (n=32) expressed as mg·kg body wt-1·d-1,and 44 AD (n=132) expressed as mg/d were collected.The models predicted a neutral calcium balance (defined as calcium output (Y) equal to calcium intake (C)) at intakes of 460 mg/d (Y=0.60C+183.98) and 8.27 mg·kg body wt-1·d-1 (Y=0.60C+3.33)for IPD,or 409 mg/d (Y=0.66C+139.00) for AD.Calcium requirements at upper intakes were higher than that at lower intakes in all these models.Conclusion Calcium requirement for Chinese adults 18-60 years of age approximately ranges between 400 mg/d and 500 mg/d when consuming traditional plant-based Chinese diets.

OBJECTIVETo explore the clinical effect of combination of acupressure and magnetic sticker on the quality of life (QOL) including appetite, defecation, and sleep in patients with advanced gastroenteric tumor.

METHODSTotally 147 patients with advanced gastroenteric tumor were assigned to 4 groups according to different treatment methods, i.e., the supportive treatment group (A, 20 cases), the acupressure treatment group (B, 41 cases), the magnetic sticker treatment group (C, 40 cases), and a combination of acupressure and magnetic sticker treatment group (D, 46 cases). They were respectively treated with different methods, supportive treatment for group A, acupressure for group B, magnetic sticker for group C, and a combination of acupressure and magnetic sticker for group D. The scores of food intake, defecation frequency, sleep time, Karnofsky, and QOL were compared before treatment and at day 14 after treatment.

RESULTSAfter treatment, the scores of food intake, defecation frequency, and sleep time were obviously improved in B, C and D groups (P < 0.01). There was statistical difference between group D and group A (P < 0.01). In addition, in comparison with A group, both Karnofsky score and QOL score increased in B, C and D groups (P < 0.01).

CONCLUSIONThe assisted therapy of the combination of acupressure and magnetic sticker could ameliorate QOL such as the digestive functions and sleep in patients with advanced gastroenteric tumor.
