Objective:To aralyze the clinical characteristics of Chlamydia pneumoniae infection in Beijing.Methods:Based on Beijing Respiratory Pathogen Surveillance System, acute respiratory infection patients were recruited from 35 different types of sentinel hospitals in Beijing. Their epidemiological and clinical data were systematically collected and clinical specimens were also obtained. Nuclear acid testing was performed for 30 types of respiratory pathogens (including Chlamydia pneumoniae). The identified patients of Chlamydia pneumoniae infection were divided into two groups, the acute upper respiratory tract infection (AURI) group and pneumoniae group. The differences in clinical characteristics, laboratory examination and prognosis were compared by using independent sample t test, Mann-Whitney U test, χ 2 test or Fisher′s exact probability test. Results:A total of 119 patients of Chlamydia pneumoniae infection were included, including 12 patients in the AURI group and 107 patients in pneumoniae group. Chlamydia pneumoniae infection mainly occurred in people aged from 5 to 44 years, accounting for 81.5% (97/119). The three most common clinical symptoms were cough (92.4%, 110/119), fever (88.8%, 95/107), and sputum production (76.5%, 91/119). White blood cell counts increased in 39.3% (46/117) of patients. Neutrophile granulocyte proportion increased in 39.7% (46/116) of patients. Platelet count increased in 36.9% (41/111) of patients. An increase of the creatine kinase MB isoenzyme (CKMB) was observed in 12 pneumonia patients (24.5%, 12/49). Radiological examination showed that 90.6% (87/105) of patients in the pneumoniae group had pulmonary parenchymal changes; the lesion occurred most commonly in the lower right lung lobe (34.3%, 36/105) and the lower left lung lobe (27.6%, 29/105). Although 73.8% (79/107) of patients in the pneumoniae group were hospitalized, no case received intensive care unit or mechanical ventilation. As to outcomes, one patient developed respiratory failure and 6 patients suffered myocardial injury. No death was observed in this study. The median days of hospitalization and course of illness for pneumonia patients M( P25, P75) were 10.0 (7.0, 13.0) days and 18.0 (13.5, 22.0) days, respectively. Conclusion:Generally, Chlamydia pneumoniae infections in Beijing from 2015 to 2019 were mild, and the main clinical manifestations were cough, fever and sputum. However, most patients in the pneumoniae group caused by Chlamydia pneumoniae still required hospitalization but with a better outcome.

Objective:To retrieve, evaluate and summarize the evidence of perioperative delirium prevention and care in elderly patients with fractures, and provide a basis for standardized prevention, care and management in clinical practice.Methods:The evidence was systematically retrieved from the Guidelines International Network, National Guidelines Library, Institute for Healthcare Optimization, UpToDate, BMJ Best Practice, Joanna Briggs Institute Center for Evidence Based Health Care, Cochrane Library, Yimaitong, CINAHL, Embase, BMJ, PubMed, CNKI , Wanfang, and China Biology Medicine disc (CBMdisc) , including guidelines, evidence summary, systematic reviews, best practice information, and randomized controlled trials (RCT) published up to December 1, 2019.Results:Finally, 15 articles were included, including 2 clinical decision-making, 5 guidelines, 5 systematic reviews, 2 summaries of evidence, and 1 RCT. The best evidence included 11 aspects such as delirium risk factor assessment, assessment tools, assessment timing, and qualifications of assessors, with a total of 25 pieces of evidence.Conclusions:Perioperative delirium in elderly patients with fractures has not yet gained the full attention from healthcare professionals. Medical institutions should establish standardized procedures for the evaluation, prevention, and care of elderly patients with fractures based on evidence-based evidence transformation, improve the health education system for medical staff and patients, formulate corresponding norms, improve the level of delirium care, and improve patients' outcomes.

Objective: To study the antipyretic, anti-inflammatory and analgesic effects of Yinhaojiere mixture and the antipyretic effect of Ilex asprella. Methods: The experiments of mice ear edma induced by xylene, the increase of capillary permeability by acetic acid and the sterilized cotton caused rat groin granulation tissue hyperplasia were used to study the anti-inflammatory effect of Yinhao-jiere mixture; the hot-plate tests and the acetic acid writhing test were applied to research the analgesic effect of Yinhaojiere mixture. In addition, the dry yeast induced fever in rats was employed to explore the efficacy of antipyretic agents in Yinhaojiere mixture and Ilex asprella water extract. Results: Yinhaojiere mixture could obviously inhibit the inflammation of the peritoneal cavity of mice ( P <0. 05). The inhibition of Yinhaojiere mixture against ear swelling induced by p-xylene was significant. Yinhaojiere mixture could sig-nificantly increase the pain threshold. Especially, Yinhaojiere mixture had significant antipyretic effect (P<0. 05). In the anti-inflam-matory, analgesic and antipyretic experimetns, there were no significant differences between the middle and high dose groups of Yinha-ojiere mixture and indomethacin group (P>0. 05). Conclusion: Yinhaojiere mixture with the Ilex asprella as the main ingredient has notable anti-inflammatory, analgesic and antipyretic effects, and Ilex asprella exhibits anti-inflammatory, analgesic effects, and its anti-pyretic effect is more significant.

Objective To explore the compound compatibility regulation of oral traditional Chinese medicines (TCM) for the prevention and treatment of infantile repeated respiratory infection.Methods The oral TCM compound literatures for the prevention and treatment of infantile repeated respiratory infection were collected from four databases,including China Biology Medicine disc,CNKI,VIP Periodical and Wanfanf Data.The retrieval time was from January 2006 to July 2006.Then the TCM oral compound prescriptions meeting the requirements were obtained by the literature arrangement and performed the terms standardized processing for extracting the information and establishing Excel table.Then the Kaiyuan software package R i386 3.3.0 was used to conduct the drug frequency,association rules analysis and clustering analysis.Results A total of 311 prescriptions were screened out and 208 kinds of traditional Chinese medicine were analyzed.It was found that the higher compatibility frequencies of TCM were atractylodes,radix glycyrrhizae,windproof,radix astragali,radix pseudostellariae,poria cocos,dried tangerine or orange peel,etc.;the strong association rules prompted that modified Yupinfeng Powder composed of core medicines such as astragalus,atractylodes and windproof was the basic formula for prevention and treatment of infantile repeated respiratory infection;the clusters analysis found some TCM societies such as emembranous Astragalus mongholicus-keel-oysters,Atractylodes-Poria cocos-licorice-Astragalus mongholicus-dangshen.Conclusion The drug frequency,association rules analysis and clustering analysis can reveal the compatibility rules of TCM prescriptions for preventing and treating infantile repeated respiratory to provide reference basis for optimizing the clinical prescription and improving the curative effect.

Objective To investigate the relationship between indoor radon concentration and air exchange rate for new residential building.Methods The indoor radon concentration and air exchange rate were measured in two new roughcast houses in Guangzhou and Hefei,respectively.The radon concentration was measured using radon instrument.The air exchange rate was measured by using tracer gas dilution method.Results The indoor radon concentrations measured in Guanzhou for two bedrooms in a 48-hour closed condition were 106 and 115 Bq/m3,the range of 17-181 and 6-224 Bq/m3.Air exchange rates were 0.16/h and 0.21/h.In Hefei,the twice measured values for one bedroom were 148 and 186 Bq/m3,the range of 8-224 and 14-290 Bq/m3,and air exchange rates were 0.14/h and 0.12/h.The indoor radon concentration exponentially decreased with the increase of air exchange rates.Conclusions Attention should be paid to the indoor radon pollution issue that may arise in new residential buildings of energy-saving design due to low air exchange rate.

Objective To observe the effect of high quality nursing on adverse emotion and quality of life of patients with colorectal cancer during hospitalization.Methods A total of 40 pa-tients with colorectal cancer were chosen in our hospital as the research objects,and the patients were randomly divided into control group with routine nursing and observation group with high quality nursing by digital form method.Postoperative Hospital Anxiety and Depression Scale (HAD)scores and SF-36 of quality of life were observed.Results Before intervention,there was no significant difference in scores of depression,anxiety and SF-36 (P >0.05).After intervention, depression and anxiety score in observation group was lower than that in control group,and SF-36 score was higher than that in control group,which revealed that the differences were significant (P<0.05).Conclusion High quality nursing plays a positive role in adverse emotion and postopera-tive life quality.
