Objective:To deeply study and explore the cognitive and barrier factors of clinical nurses' nutrition management in patients with pressure injury (PI), and provide evidence for developing quantifiable standardized management model and strengthening individualized nutrition management.Methods:A semi-structured in-depth interview was conducted with 11 nurses. The NVivo10.0 software and Colaizzi's 7-step analysis of phenomenological data were used to analyze interview data.Results:The study summarized four themes that hindered nutrition management: subjective judgment bias; education training lags behind and radiates one-sided; lack of policy and configuration; conflict between workload, roles and perceptions.Conclusions:There are many obstacles to the implementation of nutrition management in patients with PI. An objective, feasible and standardized nutrition management plan should be established, support should be provided by policy, configuration and information system, and relevant knowledge training and multi-team cooperation should be strengthened to improve patient life.

Objective To observe the inhibition effect of Shenkang 2 on rats'HPA axis,and provide theoretical basis for clinical application of steroid withdrawal and maintenance in the treatment phase.Methods To built the HPA axis suppression rat model by using high-dose glucocorticoids,when the hormone reduced to low-dose,traditional Chinese medicine Shenkang 2 were administrated.Serum ACTH,cortisol levels,adrenal index,adrenal pathological differences were observed before and after the treatment of Shenkang 2 among the treatment group,hormone control group and normal group.Results Serum ACTH,cortisol and adrenal index slowly recovered after hormone withdrawal in beth treatment group and the hormone control group,serum ACTH,cortisol and adrenal index in the treatment group rebounded faster than that in the control group,the atrophy of fascicular zone of adrenal cortex and cell disarrangement was lighter in the treatment group than that in the control group.Conclusions Shenkang 2 can improve the suppression effect of glucocorticoid-induced HPA axis suppression.

Objective To investigate the application of get-well treatments in the suffers after thorax opera- tion over 70 years old. Methods 68 suffers after thorax operation over 70 years old were divided to two groups. Comparison group( n = 32 ) is actualized general nurse. Experiment group( n = 36) is actualized lung function exercise before operation, and get-well treatments after operation, such as psychologic get-well, deep breath, abdominal breath, effective cough and sputuming, applying apparatus training breath; exercise limbs and body, atomization in- breath, and so on. Results The suffers in experiment group who have lung atrophy,lung infection, liquid in the tho- rax,the time in the hospital and the time holding thorax pipe are less than the suffers in comparison group. Conclu- sion Lung function exercise before operation and effective get-well treatments after operation have significant ef- fects on old suffers.

BACKGROUND: The etiology and pathogenesis of Tourette syndrome(TS)is still unacknowledged, and related studies on the relationship between TS and hypoironemia are unavailable. Since hypoironemia has been found existed in children with TS who showed better outcomes after receiving adjuvant ferralium, thereby this study was designed to investigate the relationship between TS and serum iron.OBJECTIVE: To study the relationship between TS and serum iron.SETTING: At a nursing science department of a university-affiliated hospital, pediatric department of a university affiliated hospital and sectional hospital.PARTICIPANTS: Between June 1997 and December 2000, 45 children with TS received treatment at pediatric clinic of Chenghai sectional people' s hospital, Shantou city, who accorded with the diagnostic standards of the second edition of Chinese Psychopathy Category and Diagnostic Standards,those who were confirmed as brain organic diseases by CT and MIR were excluded.METHODS: Serum iron, hemoglobin and the number of red blood cells were determined in 45 TS children and compared with that in 38 controls.MAIN OUTCOME MEASURES: Difference of the level of serum iron and the incidence of hypoironemia between two groups.RESULTS: The level of serum iron was(12.79 ±0.67) μmol/L in experimental group, obviously lower than(19.26 ± 5.38) μmol/L in control.group( P ＜ 0. 005), the incidence of hypoironemia was 42% significantly higher than13% of control group( P ＜ 0. 005).CONCLUSION: Quite a lot of children with TS have hypoironemia that might be one of the pathogenesis factors, the possible mechanism is, as the result of hypoironemia, decreased activity of monoamine oxidase led to abnormal monoamine neurotransmitter.

[Summary] Kisspeptin is vital for the neuroendocrine regulation of GnRH secretion. Kisspeptin neurons are now recognized as a central pathway responsible for conveying key homeostatic information to GnRH neurons. A number of metabolic modulators have been proposed as regulators of kisspeptin including leptin, adiponectin, insulin, ghrelin, POMC, and neuropeptide Y. Recent data indicate that kisspeptin may have a direct role in regulating energy balance by its regulation of food intake and glucose homeostasis. Thus, kisspeptin may serve as a new connection between reproductive function and energy metabolism.

Objective To establish a real-time quantitative PCR assay for the identification of Campylobacter jejuni in fecal samples.Methods Specific primers of the PCR were designed according to the conserved sequences of Campylobacterjeju-ni,and the real-time quantitative PCR assay was established.150 cases of fecal samples were tested by both culture and PCR methods.With the culture testing results as the reference standard,the sensitivity,specificity,accuracy and repetition of the real-time quantitative PCR were validated.Kappa test was used to estimate the difference between the two detection meth-ods.Results The standard carve of the real-time quantitative PCR assay fitted the equationY=-3.51Log(X)+37.09 (R2=0.996)well.The sensitivity,specificity,and accuracy of the established method were 92.4%,95.8% and 94%,respective-ly.The theoretical detection limit of the PCR method was 102 CFU/ml,and its reproducibility was good (CV<5%).Statisti-cal analysis demonstrated that the results of the two methods were consistent,and the consistent strength was very strong (Kappa=0.88,P<0.05).Conclusion The established real-time PCR method can assay the Campylobacterjejuni in human fecal samples rapidly and accurately.

Objective To establish a real-time fluorescence PCR method to detect the drug resistance genes of pathogenic Campylobacter jejunum in human stool samples,and investigate the relationship between quinoloneantibiotic resistance and the related genes in Campylobacter jejuni .Methods According to the gyrA and gyrB gene sequences that related with the fluoroquinolone resistance in Campylobacter jejuni ,the primers of the PCR method was designed and synthesized.A rapid real-time fluorescence PCR method to detect the drug resistance genes in Campylobacter jejuni samples was established,and the optimum reaction system and conditions were screened through an optimized approach.The developed method was com-pared with the classical drug susceptibility assay.Results It was found in the compared results that,there were 8 inconsis-tent strains of Campylobacter jejuni ,2 of the 8 strains were drug sensitive but contented the drug resistance gene,while 6 strains were drug resistant but had no drug resistant gene.Conclusion The established method can be applied to detect the drug resistance relative genes of gyrA and gyrB in Campylobacter jejuni .There was some correlation between the drug re-sistance representation and its genotype,but this point requires further studies.

Objective To study the effects of the numbers of the canalith repositioning procedure on the treatment of benign paroxysmal positional vertigo(BPPV).Methods A clinical study was conducted on 68 BPPV patients using randomized controlled methods.The canalith repositioning procedure was performed on 34 patients in the treatment group only a day for 3 consecutive days,whereas it was performed on 34 patients in the control group once only,patients in both groups took betahistine mesylate tablets and flunarizine hydrochloride on the basis of ma-nipulative reduction.After one week and three months,the efficacy was evaluated,and the recovery situation was observed.ResuIts After 1 week of treatment,the cure rate was 82.4% in the treatment group,and 58.8% in the control group.The difference was statistically significant (P<0.05).After 3 months,the cure rate was 91.2% in the treatment group,and 85.3% in the control group,showing no significant difference (P>0.05 ).ConcIusion Based on the classifications of BPPV ,several times of manipulative reduction combined with drug treatment can im-prove short-term cure rates of BPPV and shorten healing time.

Objective To investigate the systemic stress responses after laparoscopic resection in colorectal cancer patients.Methods Sixty patients were randomized into the laparoscopic resection group (30 cases) and open resection group (30 cases) from October 2001 to September 2002 in our hospital.Analgesic dosages, recovery time of intestinal peristalsis, postoperative temperatures, C reactive protein(CRP), IL 6 and white blood cell (WBC) counts were recorded after operation. Results The changes of postoperative temperatures and WBC counts showed no significant difference between two groups.But in the laparoscopic resection group, the recovery time of intestinal peristalsis, postoperative analgesic dosages, CRP and IL 6 significantly decreased ( P

Objective Acute poisoning is frequently encountered at emergency department. This study was to investigate the epidemiology and characteristics of patients with acute poisoning who were treated at the Emergency Center, Fujian Provincial Hospital, China. Method We retrospectively analyzed the gender, age, causes of poisoning, types of poisons, poisoning route, emergency diagnoses, outcomes, and prognoses of these patients.Results Altogether 2867 patients with acute poisoning were treated from January 2004 to December 2009. The ratween 18 and 40 years old. The incidence of acute poisoning was as high as 11.33% in January each year. The incidence of poisoning was in a descending order: alcohol poisoning (54.55%), medication poisoning (25.95%), pesticide poisoning (5.65%), and drug poisoning (4.88%). Most (56.44%) of the patients with drug poisoning were under 25 years and their mean age was significantly lower than that of patients with medication poisoning or alcohol poisoning ( P ＜ 0.01 ). Approximately 69.54% of the patients were followed up after emergency treatment, 30.39% were hospitalized, and four patients died. Conclusions Acute poisoning is largely alcohol poisoning and medication poisoning in a city. The emergency green channel "pre-hospital emergency care-emergency department-hospital treatment" can significantly improve the survival rate of patients with acute poisoning.
