To explore the measures of nursing management in the treatment of large number of infants with urinary calculi. The nursing management measures included launching the preparedness and response project for sudden public health events, formulating scientific and standardized nursing management system,optimizing work flow,strengthening nurse training,focusing on the details in nursing management,implementing disinfection and isolation system seriously,and paying close attention to health education for the parents of minority infants. Scientific nursing management can ensure the treatment effectiveness and nursing safety for the infants with urinary calculi.

Objective:To study the changes of upper airway dimension and morphology in Class Ⅱ mandibular retrusion children af-ter functional treatment by Twin-block appliance.Methods:The Cone-Beam CT(CBCT)data of upper airway of the subjects were measured with Dolphin 11.5 software before and after fuctional treatment by Twin-block appliance.The comparison of upper airway di-mension and morphology between pre-treatment and post-treatment was performed by paired t-text.Results:After functional treatment the volume of total upper airway,velopharyngeal airway,glossopharyngeal airway,laryngopharyngeal airway,oropharyngeal airway,the sectional area of the inferior of the soft palate(SP),tip of the epiglotti(TE),the sagittal diameter of SP,the lateral diameter of SP and TE increased(P <0.05)in the children;the airway's shape of SP was attended to be rounder and TE to be more flat.Conclusion:Functional treatment is effective in the treatment of skeletal Class Ⅱ mandibular retrusion of children by increase of the upper airway and improvement of respiration.

Objective To find out the cut-off value of rose bengal plate agglutination test(RBPT) in rapid diagnosis of brucellosis.Methods From May to June 2009,398 people who came to the outpatient department of Inner Mongolia Center for Endemic Disease Control and Research were diagnosed brucellosis by RBPT and tube agglutination test (SAT).Tube agglutination test as a gold standard,rose bengal plate agglutination test,its authenticity and reliability were evaluated.Results Taking positive predictive value 100.0％ as the selection standard,the cut-off value of RBPT was ++ which could be used to diagnose brucellosis.The sensitivity was 83.3％; the specificity was 100.0％; the Youden index was 0.832; and the compliance rote was 89.9％.Conclusion The cut-off value ++ of RBPT to diagnosis brucellosis is worthy of clinical promotion.

Subjective cognitive decline (SCD) represents subjective complaints about cognitive decline in the absence of objective impairment in neuropsychological tests. Recently, growing evidence has suggested that SCD might be the first symptomatic stage of Alzheimer's disease (AD) spectrum disorders. However, SCD is a heterogeneous condition mixed with AD and non-AD related conditions. Hence, refinement of evidence from previous reports and standardization of the concept about SCD are needed to define appropriate target population with AD pathology. In this article, we review previous studies involving subjects with SCD, the new proposed research criteria, and characteristics of SCD in the aspect of preclinical AD. Biomarker status of SCD is also addressed. Future researches on SCD require a longitudinal follow-up with sufficient biomarker studies and proper outcome measures.

Objective To observe the incidence and explore the potential factors of nonresponse to cardiac resynchronization therapy (CRT) in patients with severe chronic congestive heart failure. Method CRT was performed in 119 patients with NYHA function class Ⅲ - Ⅳ and left ventricular ejection fraction ≤35% [96 men and 23 women, age (60.5 ± 11.3 ) years ]. Results Seven patients died for different reasons between 1 - 6 months post CRT and clinical and echocardiographic (Echo) data at 6 months post CRT were analyzed from the remaining 112 patients. The incidence of nonresponse to CRT was 28.57%.Compared to the response group, complete right bundle branch block, longer course of congestive heart failure, higher pulmonary systolic pressure and serum creatinine level and non-optimal target vessels positioning of the left venticle lead( the great cardiac vein and the middle cardiac vein)were the independent predictors for nonresponse after CRT( all P ＜ 0.05). Compared with nonresponse group, the dosages of digoxin and diuretics used for heart failure were significantly reduced in response group ( P ＜ 0.01 ).Conclusions The incidence of nonresponse after CRT was 28.57% in this patient cohort Higher pulmonary systolic pressure and serum creatinine level and non-optimal target vessels positioning of the left venticle lead ( the great cardiac vein and the middle cardiac vein) were the independent predictors for nonresponse after CRT.

The prescription combinations of traditional Chinese medicine (TCM) focuses on the taste and channel tropism, the Qi movement, as well as the compatibility according to multiple combination principles and medicinal property and flavor combination of several traditional Chinese medicines. With the in-depth study on the prescription compatibility, researchers have realized that the medicinal property theory is the core of TCM combinations. However, there is no definite method for combinations based on medicinal properties. In this paper, the authors put forward an method for designing prescription combinations based on bipartite graph and the greedy algorithm. With the medicinal property combinations of Siweilurong Pills for example, the authors proved this method could provide ideas for quickly choosing herbal medicines for prescription combinations, and discussed the prospect of this method in substituting previous and endangered herbal medicines and banned medicinal materials.

BACKGROUND: We studied the incidence of trauma caused by alcohol related accidents, and the effects that has on the occurrence, the extent, and the outcome to the patient. METHODS: In our study we studied trauma patients excluding pediatric patients(15 years old and under) who came to the Emergency department of Korea University Medical School Anam Hospital from the 1st of january 1996 to 30th of June 1996, looked into their medical records, and studied the records in a retrospective manner. The trauma patients were divided into two groups, a) alcohol-related and b) alcohol-non-related. The two groups were then subdivided according to their sex, age, the time they came in, the anatomical part of the trauma, the mechanism of their injury, the extent of the injury, the length of their hospital stay, the length of their ED stay and were seperately compared and analysed. Statistically, ANOVA and logistic regression analysis using SAS were used in the study and then was assessed in Chi-square analysis methods. RESULTS: The total of the trauma patients, added up to 832 people, 577: male and 255: female. Among this sum, 16 trauma patients were alcohol related(male:127 & female 36). 115 people were in the age group of 21-40. Compared to the non-alcohol related trauma group, the alcohol-related group had more facial & scalp injuries and tended to come in the hours between 0-6 AM. The cause of the injuries were mossy by fast-fighting and suicide, compared to mostly accidental-slipping injuries in the non alcohol-related group. There were no difference in the degree of the injury(ISS) and the length of hospital stay between the two groups, whereas the length of the stay at the ED was longer alcohol-related trauma patients. CONCLUSION: Alcohol related trauma patients were mostly in their 20s and 30s, came to the hospital at a late time it the reason for their visit were mossy because of fist fighting. In the Emergency department, because prompt and correct diagnosis is quite difficult to make in this group, their ED stay tended to be longer. We can conclude that measuring the blood alcohol level of these patients, continuing the psychological therapy and educating people is needed.
