Objective To investigate the etiological agents of hand, foot and mouth disease (HFMD) in children in spring and summer from 2007 to 2008 in Beijing and the characteristics of the disease by virus isolation and to provide the scientific evidence for prevention and treatment for HFMD. Methods During April to August, 2007 and May to September, 2008, 356 clinical specimens including 255 throat swabs and 101 vesicle fluids were collected from 256 patients with HFMD who visited the Children's Hospital Affiliated to Capital Institute of Pediatrics and children with severe HFMD with neural system complications from Ditan Hospital and Youan Hospital All of the specimens were inoculated into Vero cells for virus isolation. After the cell pathogenic effects (CPE) appeared, the isolates were identified by RT-PCR with the universal primers within 5'untranslated region of enterovirus and typed by specific primers for VP1 gene of EV71 and CA16, respectively. The throat swabs from all of 10 severe HFMD were tested for enterovirus by RT-PCR addition to virus isolation. Results Out of 256 patients, 188 were positive for enterovirus by virus isolation, with the overall positive rate of 73.4%. Among the 356 clinical specimens collected from these 256 patients, 239 enterovirus strains were isolated with the overall positive rate of 67.1%. The positive rate for virus isolation from vesicle fluid samples was 75.2% which was higher than the positive rate of isolation from throat swabs (63.9%), but the time for CPE appearing in cell culture showed no significant difference. The positive rate of virus isolation from throat swabs from children with severe HFMD was 50% (5/10) which was lower than overall positive rate (73.4%) from regular HFMD. The RT-PCR typing for virus isolates revealed that among 45 enterevirus strains isolated from the specimens collected in 2007 by the universal primer pairs, 43 were CAI6 (95.6%, 43/45) and 2 were EV71 (4.4%, 2/45), whereas for the specimens collected in 2008, out of 143 enterovirus isolates by PCR with universal primers, 117 were EV71 (82.4%, 117/142) and 24 were CA16 (16.8%, 24/142). All of 10 severe cases were positive for EV71 by RT-PCR directly from clinical specimens. Conclusion CA16 and EVT1 were the etiological pathogens of HFMD in Beijing during 2007 to 2008 HFMD seasons. The dominant type of enterovirus was different between 2007 and 2008. Enterovirus type CA16 was predominant in 2007, whereas EV71 was predominant in 2008. All of severe cases of HFMD in children in this study were caused by EV71.

【Objective】 To investigate the epidemiology of HTLV by conducting HTLV nucleic acid detection among voluntary blood donors, so as to provide basis for the decision making of blood screening strategy. 【Methods】 The HTLV blood nucleic acid(NAT) screening platform was established based on the existing NAT for HBV / HCV / HIV screening. HTLV (type 1 + 2) detection was carried out in 5 368 blood donors, and the results were analyzed. 【Results】 No NAT-yielding of HTLV- 1, -2 type was found in a total of 5 368 voluntary blood donor from January to August 2019. 【Conclusion】 Qianxinan, currently, is very low epidemic or non epidemic as none of HTLV infections was found among blood donors and no significant differences in the epidemiology of HTLV were notable between the counties and cities. It, however, still needs further investigation in the future.

Objective:To introduce and validate the Pediatric Nausea Assessment Tool (PeNAT) and the Baxter Retching Faces Scale (BARF) in the assessment of chemotherapy induced nausea in Chinese children with malignant neoplasms, and to explore the cut-off value for rescue antiemetic.Methods:A prospective descriptive study was conducted, 244 children in Sun Yat-sen University Cancer Center with malignant neoplasms who received chemotherapy were selected by convenience sampling from July to August 2021. PeNAT, BARF, Visual Analogue Scale (VAS) and the Faces Pain Scale-Revised(FPS-R) were used to assess the severity of nausea and pain before and after chemotherapy, before and 30-60 minutes after the use of rescue antiemetic or analgesic. After chemotherapy, the children also were asked the changes of nausea severity and whether antiemetic was needed.Results:A test-retest reliability was conducted on the patients with the same severity of nausea before and after chemotherapy, and the intraclass correlation coefficient of the PeNAT and BARF were 0.940 (both P<0.05). After chemotherapy, the PeNAT and BARF were 1.5(1.0, 2.0) and 2.0(0, 2.0) points, which were significantly higher than the 1.0(1.0, 1.0) and 0(0, 0) points before chemotherapy ( Z = - 9.19, - 9.09, both P<0.01). The PeNAT and BARF of 11 cases receiving antiemetic before medication were 4.0 (4.0, 6.0) and 3.0(2.0, 4.0) points, which were higher than the 0(0, 2.0) and 1.0(1.0, 2.0) points without antiemetic ( Z = - 4.03, - 3.86, both P<0.05). After chemotherapy, the correlation coefficients between PeNAT or BARF and VAS-nausea were r = 0.933, 0.957 (both P<0.01), and FPS-R were r = 0.192, 0.189 (both P<0.05). After using antiemetic, PeNAT and BARF were 2.0(2.0, 3.0) and 2.5(2.0, 4.0) points, which were significant different than the 3.0(3.0, 3.8) and 4.0(4.0, 8.0) points before using antiemetic ( Z = - 2.97, - 2.83, both P<0.05). According ROC curves and cut-off values, it was determined that PeNAT≥3 and BARF≥4 had clinical significance and require clinical intervention. Conclusions:PeNAT and BARF have excellent reliability and validity in the assessment of chemotherapy induced nausea in children with malignant neoplasms, they can effectively identify the requirement of rescue antiemetic, and evaluate the efficacy of antiemetic.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

BACKGROUNDAllergic asthma is a chronic airway inflammatory disease partly characterised by high concentration of T help 2 (Th2) cytokines in bronchoalveolar lavage fluid (BALF). There is no report on the relation of peripherally circulating blood lymphocytes and asthma. We explored the balance of Th2/Th1 cytokines in asthmatic mice. Exogenous recombinant interleukin (IL) 33 acted on murine peripheral circulating blood lymphocytes, IL-5 cytokine was selected for assessing Th2 cytokines and interferon-gamma (IFN-γ) for Th1 cytokines.

METHODSFemale specific pathogen free BABL/c mice were sensitised by intraperitoneal injection of 20 µg of ovalbumin emulsified in 1 mg of aluminium hydroxide gel in a total volume of 200 µl, and challenged for 30 minutes in 7 consecutive days with an aerosol of 2 g ovalbumin in 100 ml of PBS. Then we collected BALF and isolated lymphocytes from the peripheral blood. The lymphocytes were divided into two groups: asthmatic group and normal group. Th1/Th2 cytokines was detected by enzyme-linked immunosorbent assay (ELISA) kits.

RESULTSIn the asthma group, we found numerous eosinophils and lymphocytes on the glass slides. We then confirmed that the optimal concentration of IL-33 was 10 ng/ml and time of IL-33 stimulating lymphocytes was 24 hours. In the asthma group, the production of IL-5 was significantly increased over normal group after stimulation with IL-33 (P < 0.05) and the production of IFNγ was supressed from IL-33 stimulated lymphocytes (P < 0.05).

CONCLUSIONIL-33 acts on lymphocytes of peripheral blood increasing secretion of Th2 cytokines and inhibiting secretion of Th1 cytokines.
