Objective:To evaluate our self-designed guide device for Kirschner-wire placement in the surgery for paediatric fractures of supracondylar humerus.Methods:A retrospective study was conducted of the 117 children who had been treated for fractures of supracondylar humerus at Department of Orthopedics, The First People's Hospital of Huaian Affiliated to Nanjing Medical University from March 2019 to January 2023. There were 64 boys and 53 girls with an age of (5.8±1.5) years. By the Gartland classification, there were 67 fractures of type Ⅱ and 50 fractures of type Ⅲ. The time from injury to operation averaged (48.5±10.8) hours. The children were divided into 2 groups according to how their Kirschner-wires were placed. In the control group of 58 cases, external percutaneous Kirschner-wire placement was assisted using a syringe needle; in study group of 59 cases, external percutaneous Kirschner-wire placement was assisted using our self-designed guide device for Kirschner-wire placement. The operation time, rate of one-time placement of disposable K-wire, intraoperative fluoroscopy frequency, Baumann angle, carrying angle, fracture healing time, Flynn score of elbow joint function at the final follow-up, and postoperative complications were compared between the 2 groups.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). The 117 pediatric patients were followed up for (15.3±3.2) months after operation. The operation time [(30.6±4.5) min] and intraoperative fluoroscopy frequency [(15.6±2.1) times] in the study group were significantly less than those in the control group [(40.6±7.3) min and (23.7±4.9) times], while the rate of one-time placement of disposable K-wire in the study group was significantly higher than that in the control group [84.2%(149/177) versus 32.2%(56/174)] ( P<0.05). There were no significant differences in Baumann angle, carrying angle, fracture healing time, or Flynn score of elbow joint function at the final follow-up between the 2 groups ( P>0.05). The incidence of complications in the study group (6.8%, 4/59) was significantly lower than that in the control group (20.7%, 12/58) ( P<0.05). Conclusions:Our self-designed guide device for Kirschner-wire placement is simple and convenient to use. In the surgery for paediatric fractures of supracondylar humerus, it can improve the rate of one-time placement of disposable K-wire, reduce intraoperative fluoroscopy, and decrease the incidence of complications.

To study the carriage status of drug susceptibility, clonal complex groups, serotypes, surface proteins and virulence genes of Streptococcus agalactiae from respiratory specimen sources. A total of 35 strains of S.agalactiae meeting the criteria were collected from 3 hospitals in 2 locations, Tangshan and Jinan. The age span of the patients was 3 days-92 years, and the percentage of elderly patients&ge;60 years was 71.5%.The susceptibility to 9 antimicrobial drugs was measured and analyzed using the micro broth dilution method. The strains were 100.0% sensitive to penicillin, linezolid, vancomycin, and ceftriaxone; However, it exhibits high resistance rates to erythromycin, clindamycin and levofloxacin, at 97.1%, 85.7% and 82.9% respectively; and the resistance rates to tetracycline and chloramphenicol were 34.3% and 14.2%, respectively. Genome sequence determination and analysis showed that 16 resistance genes were detected in 35 strains, among which: macrolide and lincosamide resistance genes were mainly ermB, with a carrying rate of 74.2%; tetracycline resistance genes were mainly tetM, with a carrying rate of 25.7%; in addition, the mutation rates of the quinolone resistance determinants gyrA and parC were 88.5% and 85.7%, respectively. 35 strains belonged to 6 ST types and 4 clonal groups, with CC10/ST10 as the main one, accounting for 62.8%; they contained 4 serotypes of Ⅰb, Ⅱ, Ⅲ, and Ⅴ, as well as 1 untyped strain, with serotype Ⅰb as the main one, accounting for 65.7%. The strains carried three pilus types, PI1+PI2a, PI2a and PI2b types, respectively, and detected five surface proteins, alpha, alp1, rib, srr, and r df_0594, and seven virulence factors, cba, cfb, cylE, fbsA, hylB, l mb, and pavA. Overall, S.agalactiae isolated from respiratory tract specimens is predominantly sourced from elderly patients, with CC10 strains being most prevalent. These strains harbor multiple drug-resistant and virulence genes, demonstrating elevated resistance rates to macrolides, lincosamides, and quinolones. This emphasizes the necessity for vigilant attention to the health threat posed by S. agalactiae from respiratory tract speciments of elderly patients.

Objective:To analyze the drug resistance characteristics of Klebsiella pneumoniae in the nasopharynx of hospitalized patients in North China from 2022 to 2023. Methods:From November 2022 to July 2023, nasopharyngeal swabs were collected from 100 inpatients in Affiliated Hospital of North China University of Science and Technology, and Klebsiella pneumoniae was isolated and cultured. At the same time, the clinical data of the patients were collected, including gender, age, department, clinical diagnosis of disease type, etc. The minimum inhibitory concentration of strains was detected by an automatic bacterial drug sensitivity system. The drug resistance genes, ST types, capsule serotypes and population structure of the strains were analyzed by whole genome sequencing and data analysis. Results:Klebsiella pneumoniae was isolated from 55 nasopharyngeal swabs of 100 inpatients(55.00%). Among the 55 inpatients with Klebsiella pneumoniae in the nasopharynx, 70.91% (39/55) were male, with an age distribution concentrated between 61 and 80 years old (58.18%, 32/55), and 50.91% (28/55) were in intensive care units (ICU). The main underlying disease type was nervous system disease (49.09%, 27/55). The results of drug sensitivity showed that the non-susceptibility rates of 55 strains of Klebsiella pneumoniae to cephalosporins, quinolones, aztreonam and nitrofurantoin were all more than 80.00%. Twenty-eight carbapenem-resistant Klebsiella pneumoniae strains (50.91%), 47 extended-spectrum β-lactamase producing strains (85.45%), and 48 multi-drug-resistant strains (87.27%) were detected. A total of 11 antibiotic resistance genes were detected, including carbapenems (carrying rate 76.36%) and extended-spectrum β-lactamase (carrying rate 96.36%). The 55 strains could be divided into 17 ST types, and the most common type was ST11 (25.45%). The 55 strains were divided into 18 capsular serotypes, among which K102 was the most prevalent (23.64%). OXA-1_ST307_K102 (21.82%) and KPC-2_ST5492_K125 (18.18%) were the dominant clones, distributed in the Department of Neurosurgery and ICU. The result of whole genome sequence analysis showed that there were four clusters with high homology among the 55 strains. The strains from the ICU formed two independent clusters, and strains from the Neurology ICU and Neurosurgery department formed one cluster respectively. Conclusion:The carrying rate of Klebsiella pneumoniae in the nasopharynx of inpatients is high, and the drug resistance of the strains is serious. There are many types of drug-resistant genes.

Objective: To study the correlation between ceramic and chronic obstructive pulmonary disease (COPD), and explore its related risk factors. Methods: In January 2021, five representative ceramic enterprises were selected from Chancheng District, Nanhai District, Gaoming District and Sanshui District of Foshan City. The ceramic workers who came to Chancheng Hospital of Foshan First People's Hospital for physical examination from January to October 2021 were selected as the research objects, and 525 people were included. Conduct questionnaire survey and pulmonary function test. Logistic regresion was performed to analyze the influencing facters of COPD among ceramic workers. Results: The subjects were (38.51±1.25) years old, 328 males and 197 females, and the detection rate of COPD was 9.52% (50/525). The incidence of respiratory symptoms such as dyspnea, chronic cough, wheezing and chest tightness, the detection rates of abnormal lung age, abnormal lung function and COPD in males were higher than those in females (P<0.05). The logistic regression analysis showed that male, age, working years, smoking status and family history of COPD were the risk factors for COPD among ceramic workers (P<0.05) . Conclusion: The ceramic workers are the high risk population of COPD. We should do a good job in health education, and do a regular physical examination to find the changes of lung function in time, and prevent the occurrence of COPD as soon as possible.

Cancer anorexia/cachexia syndrome (cancer anorexia cachexia syndrome, CACS) is a common complication in advanced cancer patients, which is characterized by reduced feeding, sustained weight loss, general fatigue and weakness. CACS related symptoms make patients suffer from a series of adverse psychosocial effects, such as anxiety, pain and social isolation, thus bringing serious adverse effects on patients′ individuals, families and society. This paper reviewed the symptoms associated with CACS and their psychosocial effects, as well as the interventions related to adverse psychosocial effects, in order to provide theoretical reference for alleviating psychosocial distress and improving health-related quality of life of patients with CACS.

Objective:To translate the Health Literacy of Caregivers Scale-Cancer (HLCS-C) into Chinese and test its reliability and validity.Methods:The British translation model was used to translate and back translate the English version scale, and the Chinese version scale was initially verified and revised through expert consultation and pre-test. From June to September 2021, 242 caregivers of cervical cancer patients admitted to Shandong Cancer Hospital were selected by convenient sampling. The revised Chinese version of HLCS-C was used to investigate the caregivers for reliability and validity test. A total of 242 questionnaires were distributed and 226 valid questionnaires were recovered.Results:There were 44 items in the Chinese version of HLCS-C. The exploratory factor analysis showed that the scale included 8 dimensions, namely cancer information collection, cancer information mastery, social support, cancer related communication with patients, understanding of patients' needs and preferences, health and healthcare service use, health information processing, and active participation with medical and nursing staff, with a cumulative variance contribution rate of 73.448%. The scale-level content validity index ( S- CVI) was 0.981, and the item-level content validity index ( I- CVI) was 0.833 to 1.000. The total Cronbach's α coefficient of the scale was 0.946, and Cronbach's α coefficient of each dimension was 0.700 to 0.945. The total half-reliability coefficient of the scale was 0.791, and the half-reliability coefficient of each dimension was 0.635 to 0.867. Conclusions:The Chinese version of HLCS-C has good reliability and validity, and can be used as an assessment tool for the health literacy of cervical cancer caregivers.
