Objectives To conduct nutritional risk assessment analysis of hand-foot-mouth disease in children and to explore rational and feasible nutritional intervention. Methods The information of children with hand-foot-mouth disease in three hospitals in Guilin area was collected by ifxed-spot continuous sampling. Inquiry investigations, physical mea-surements combined with clinical diagnosis were undertaken, and nutritional risk assessment and management were con-ducted by the malnutrition screening tool of children (STAMP scoring). Those with STAMP scores ≥4 were considered at high nutritional risk. Nutritional risk reassessment was conducted on children with high nutritional risk after nutritional intervention and management. Results A total of 192 children with hand-foot-mouth disease were selected. The occur-rence rate of high nutritional risk was 68.75%(132/192). The hospitalization time of patients with high nutritional risk was prolonged and the hospitalization expense was increased apparently. The nutritional support treatment and nutritional edu-cation were undertaken on the children with high nutritional risk. The incidence of high nutritional risk from admission to discharge decreased from 68.75%to 36.98%(P<0.05). The clinical outcomes of those children accepting nutritional inter-vention were signiifcantly improved (P<0.05). Conclusions The occurrence and prognosis of hand-foot-mouth disease is closely related to the nutritional status of children, so nutritional risk assessment, nutritional intervention and management should be performed as early as possible.

Objectives To validate the Screening Tool for the Assessment of Malnutrition in Pediatrics (STAMP) in hospitalized pediatric patients, and to assess the nutritional status and nutritional risk using STAMP. Methods the nutritional status of hospitalized pediatric patients was investigated by adopting STAMP. The STAMP score≥4 was deifned as a high standard of nutritional risk. Results Among 1 506 hospitalized children, children with high nutritional risk accounted for 26.56%. The overall prevalence of malnutrition and stunting was 19.12%and 10.16%, respectively. There was signiifcant diffe-rence in stunting among each department (P<0.05), which was the highest in department of internal pediatrics. The proportion of patients receiving nutritional support was 10.09%. Among them, the rate of parenteral and enteral nutrition support was 7.84%and 2.92%, respectively. The ratio of parenteral nutrition to enteral nutrition was 2.68:1. After intervention to hospitalized pa-tients with high nutritional risk, the overall prevalence of high nutritional risk decreased from 26.56%at admission to 21.71%at discharge (P<0.05). Conclusions STAMP can objectively relfect the possible malnutritional risk in hospitalized pediatric patients. The nutrition condition of the pediatric patients can be improved through nutritional risk management.

Total elbow arthroplasty was initially used to manage the rheumatoid arthritis of elbow. With the developement of technology in recent decades, the indication of total elbow arthroplasty include the trauma associated unstable joint, traumatic arthritis and distal humerus fractures in elderly. But the high risk of complications, which includes infection, ulnar nerve deficit and tricep insufficiency, is still an unsolved issue. The most widely used approach nowadays is the Bryan-Morrey approach, while some authors also report triceps on approach recently. This article is an overview in approaches and biomechanical researches of total elbow arthroplasy by reviewing the domestic and overseas involved literatures.

This paper discussed the application of designing experiments from scientific research in Micro-biology courses and its effects on the teachers and students. The problems of the application of designing experiments in Microbiology courses were analyzed. The practice of the teaching reform showed that it give great advantages for the undergraduates with the enhancement of their ability on theory application and sci-entific innovation. This teaching reform could be widely popularized.

Various teaching methods were used in occupational health and occupational medicine teaching,including problem based learning,multimedia teaching,bilingual teaching,case based learning and practice teaching methods when being confronted with new situation of occupational health and occupational safety.These methods are mean to encourage students' enthusiasm,cultivate students' comprehensive ability and enhance their sense of social responsibility and mission.Results showed that these methods improved the quality of teaching and achieved good teaching results.

Objective To explore the characteristics of dipyridamole 201 Tl myocardial perfusion imaging (MPI) SPECT in patients with dilated cardiomyopathy. Methods Thirty patients with dilated cardiomyopathy underwent pharmacological stress 201Tl MPI SPECT after intravenous infusion of dipyridamole (0. 56 mg/kg) for 4 min. The early and delayed SPECT images were acquired respectively at 10 and 240 min after 201Tl injection. The images were analyzed and reported by two or three experienced nuclear medicine physicians. Results All patients were found to have abnormal perfusion patterns at delay imaging, however 90.00% (27/30) were also abnormal at early images. Six patients had reverse redistribution. Conclusion Dipyridamole 201Tl MPI SPECT imaging may be of some value for the assessment of patients with dilated cardiomyopathy.

Objective:To determine the prevalence of Helicobacter pylori (Hp) infection in orthotopic liver transplantation (LT) recipients, and to study the efficacy and safety of Hp eradication therapy.Methods:13C-urea breath test was carried out between July 2018 and October 2019. There were 104 males and 26 females with an average age of 52.1 year for these LT recipients who were regularly followed-up in the Organ Transplant Center, the Affiliated Hospital of Qingdao University. Propensity scoring was used to match age and gender in a ratio of 1∶3. A healthy group of individuals consisting of 299 males and 91 females, with an average age of 51.8 years, were selected as the control group also in a ratio of 1∶3. All patients underwent 13C-urea breath test to evaluate Hp infection and results of quadruple therapy. Results:The prevalence of Hp infection among the LT recipients was 18.5%(24/130) which was significantly lower than the control group 36.4% (142/390) (χ 2=14.400, P<0.001). Among the recipients who received LT and 13C-urea breath test for less than 1 year, 1-3 years and more than 3 years, the prevalences of Hp infection were 14.3% (6/42), 17.8%(8/45) and 23.3%(10/43), respectively. Although the prevalence of Hp showed a gradually increasing trend, no correlation between Hp infection and duration from LT was observed (χ 2=1.321, P=0.517). Seventeen Hp positive recipients underwent Hp eradication therapy. The success rate of Hp eradication was 100.0%(17/17). Immunosuppressant concentration was monitored regularly in 10 patients. During Hp eradication, the blood concentration of immunosuppressant increased from 1.7 to 3.6 times, and the drug dosage was reduced to one half to one third of what it was before Hp eradication. Seven of these 17 recipients suffered from adverse effects caused by increased levels of blood concentration of immunosuppressants, including headache, hypertension, insomnia and irritability. Normal liver and kidney functions were observed during eradication. Conclusion:In this study, the prevalence of Hp infection among liver transplant recipients was 18.5%. The success rate of Hp eradication was 100% using bismuth-containing quadruple therapy. The dosage of immunosuppressant required to be monitored, and if necessary, adjusted during eradication to reduce adverse side effects.

Objective To discuss the methods and effects of interferon atomization combined with mouth nursing in the treatment of hand-fcot-and-mouth disease. Methods 46 patients were randomly divided into 2 groups, which were both given the regular defervesce and heteropathy. Moreover, the treatment group was treated with 50u α-2b of interferon atomization combined with mouth nursing. Results Compared with the control group, the treatment group took less time on defervesce and recovery of mouth ulcer. And the difference was statistically significant (P < 0.01). Conclusions Interferon atomization combined with mouth nursing can treat hand-foot-and-mouth disease effectively.

Fractures of distal humerus in elderly patients are difficult to treat, as diminished bone mineral quality and increased trauma-associated articular surfaces destruction may make stable joint reconstruction even more difficult. In active patients, internal fixation is still a primary choice because of use age of total elbow replacement, but disagreements have still existed on how to treat these fractures in elderly patients. In the past years, treatment of fractures of distal humerus make much progress, including the introduction of dual plates fixation, widespread application of three-dimensional CT reconstruction, recognition of complicated fractures, understanding of the parallel plate technique, application of periarticular plates, and the selective use of total elbow arthroplasty. This article is an overview in treating options of fracture of distal humerus in the elderly patients by review the civil and overseas involved literatures.

Based on the physiological properties of ammonium-resistant N2-fixingbacterium ( Klebsiella oxytoca NG13/pMC73A), the fermentation technology of it was studied. The basic medium of high-density culture was established, with glucose as carbon source coupled with appropriate nitrogen source and inorganic salts. At the middle and late phase of culture, glucose and ammonia were added to supply carbon source and nitrogen source, stabilizing the pHat 6.5 ~ 6.8. Optimal level of dissolved oxygen was kept by controlling aeration and stirring rate. Bacterium number of Klebsiella oxytoca NG13/pMC73A reached 600 ~ 700 x 10s cfu/mL at the end of culture. Compared with previous technology, bacterium number was increased by more than ten-fold with a comparable culture period.
