[Objective] To evaluate the effect of fast rehabilitation nursing pathway in patients after artificial hip replacement.[Methods] 86 patients underwent artificial hip replacement were randomly divided into the control group and the experimental group with 43 cases in each group.The control group received routine care,while the experimental group was given fast rehabilitation nursing pathway.Anxiety and pain at 48h after operation were evaluated,and hip joint function(Harris score)was evaluated six months after operation.[Results] Compared with the control group,anxiety and pain score at 48h after operation decreased markedly,and Harris score six months after operation increased significantly.[Conclusions] Fast rehabilitation nursing pathway can reduce both the short-term and long-term efficacy of patients after artificial hip replacement.

Objective The homological analysis of a foodborne disease outbreak event that occurred on July 15, 2022, in Sanya was carried out to provide scientific basis for clinical treatment, incident tracing and prevention and control, and to explore the feasibility of pulsed field gel electrophoresis (PFGE) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) in the homology analysis of Salmonella bacteria. Methods The traceability analysis of food poisoning incidents was accurately analyzed through the combination of traditional bacterial detection methods, PFGE, MALDI-TOF MS and the clinical symptom, epidemiological characteristics. Results In this outbreak, 14 cases of poisoning symptoms such as fever, nausea, and vomiting appeared, all of which had a history of dining in the same restaurant, with similar onset and clinical manifestations. Among them, one was the chef who made the fried rice in the restaurant. The pathogen culture and identification showed that it was caused by Salmonella typhimurium and Salmonella choleraesuis. Among the 14 cases of patients, 5 cases of Salmonella choleraesuis, 3 cases of Salmonella typhimurium, with the positive rate of 57.14% (8/14). One case of environment and two cases of food were detected. The result of PFGE showed nine PFGE types, 95.00% homology for 7 strains, and 94.00% homology for 4 strains. Conclusions The food poisoning was caused by eating egg fried rice containing Salmonella choleraesuis and pork intestine containing Salmonella typhimurium. In the future, , it is necessary to strengthen the risk monitoring of food contamination and harmful factors, to ensure food safety from the source of food supply, and to prevent the occurrence of foodborne infection events. At the same time, it is also crucial to standardize the health check of related personnel, and to conduct multi-channel education on the harm and prevention of foodborne diseases.

Objective To investigate the effects of bundle care on feeding intolerance in premature infants. Methods A total of 80 premature infants admitted to the neonatal department of a Class Ⅲ Grade A hospital in Changzhou from August 2017 to February 2018 were recruited. The study subjects were randomly divided into experimental group and control group by random number table method, with 40 cases in each group. The two groups of premature infants were treated with bundle care and routine nursing respectively. The effects of the two regimens on the occurrence of feeding intolerance, growth and development indicators of premature infants from birth to 14 days were compared. Results After the intervention, The incidence of feeding intolerance of preterm infants in the experimental group was less than that in the control group, and the difference between the two groups was statistically significant (P＜ 0.05). Compared with the control group, the growth of body weight, head circumference and length of preterm infants in the experimental group was significantly greater than that in the control group, with statistical significance (P＜0.05). Conclusions The bundle care can effectively reduce the occurrence of feeding intolerance of premature infants, improve the feeding quality of premature infants, and provide theoretical basis for improving feeding intolerance of premature infants, which can be applied in clinic.

Objective To investigate the characteristics of body composition (BC) in gout patients and its clinical significance. Methods Consecutive gout patients were recruited between August 2017 and December 2018. Demographic information, clinical characteristics and comorbidities were collected. BC was assessed by bioelectric impedance analysis including body fat percentage (BF% ), trunk and limb BF%, appendicular skeletal muscle index. Overfat was defined by BF%≥25% for male and≥35% for female. The association between BC and serum uric acid (sUA) was evaluated by multiple linear regression. Results A total of 362 gout patients were recruited with median age 38 (30, 52) years, 96.1% (348/362) were male. Mean sUA was(551±133)μmol/L. The mean BF% was (25.8±6.4)% with 53.6%(194/362) patients overfat. Male gout patients with overfat showed more affected joints [4(2, 6) vs. 2(2, 5)], higher sUA [(576 ± 126)μmol/L vs. (523 ± 134) μmol/L], higher prevalence of dyslipidemia [70.1%(131/187) vs. 54.0%(87/161)], metabolic syndrome [60.8%(118/187) vs. 28.0%(47/161)], fatty liver [58.2%(113/187) vs. 35.1%(59/161)] and hypertension [44.4%(83/187) vs. 25.5%(41/161)] than male patients with normal fat (all P<0.05). Their BF% , trunk BF% and limb BF% were positively correlated with the numbers of affected joints, sUA, metabolic syndrome, fatty liver, and hypertension, respectively (r=0.154-0.435, all P<0.05). Multivariable linear regression suggested that BF% (β=4.29, P=0.020) and trunk BF% (β=9.11, P=0.007), but not limb BF% , were positively correlated with sUA. Conclusion Overfat is very common in gout patients. The proportion of trunk fat in male patients is positively correlated with sUA. When assessing obesity in gout patients clinically, body composition analysis should be performed simultaneously.

Objective:To investigate the etiology, pathogenesis, clinical manifestations, and treatment of acute pancreatitis (AP) complicated with spleen infarction.Methods:A case of AP combined with splenic infarction was retrospectively analyzed and the literature was reviewed.Results:AP complicated with splenic infarction suggested that the patient′s condition was serious. The impairment of splenic immune function caused by splenic infarction may be an important cause of severe acute pancreatitis (SAP). Early detection and active treatment can obtain a good prognosis, and anticoagulant or antiplatelet aggregation treatment was not the key treatment.Conclusions:AP combined with splenic infarction may be an risk factor for SAP.

Objective:To study the clinical characteristics of ureaplasma urealyticum (UU) infection in preterm infants with gestational age <34 weeks.Methods:From January 2017 to December 2021, premature infants with gestational age <34 weeks admitted to neonatal department of our hospital were enrolled in this prospective cohort study. UU-DNA from respiratory tract samples were examined using quantitative fluorescence polymerase chain reaction method. The infants were assigned into UU (+) group and UU (-) group. Perinatal factors and clinical characteristics were compared between the two groups.Results:A total of 182 preterm infants were enrolled, including 59 cases (32.4%) in UU (+) group and 123 (67.6%) in UU (-) group. UU (+) group had significantly lower gestational age and birth weight and significantly higher incidences of vaginal delivery, premature rupture of membranes (PROM) >18 h and maternal chorioamnionitis than UU (-) group ( P<0.05). Compared with UU (-) group, UU (+) group had significantly higher leucocyte count, neutrophil count and interleukin-6 at 1, 24 and 72 h after birth ( P<0.05). No significant differences existed in C-reactive protein and procalcitonin between the two groups at each time point ( P>0.05). In UU (+) group, the incidences of intrauterine pulmonary infection and bronchopulmonary dysplasia (BPD) were higher and the incidence of respiratory distress syndrome was lower than UU (-) group ( P<0.05). No significant differences existed in the incidences of intraventricular hemorrhage, periventricular leukomalacia, feeding intolerance, necrotizing enterocolitis, retinopathy of prematurity between the two groups ( P>0.0 5). UU (+) group had significantly longer duration of oxygen therapy than UU (-) group ( P<0.05). No significant differences existed in the duration of invasive mechanical ventilation and hospital stay between the two groups ( P>0.05). Conclusions:Preterm infants <34 weeks with positive UU in respiratory tract secretions have higher incidences of vaginal delivery, PROM>18 h and maternal chorioamnionitis. Leukocyte and neutrophil count and interleukin -6 are higher in these infants. They need prolonged oxygen therapy and have increased risks of intrauterine pulmonary infection and BPD.

Objective:To explore the performance of the commonly used whole blood C-reactive protein (CRP) detection systems and give related recommendation on the performance requirements of detection systems.Methods:A total of 7 540 venous blood samples from 26 maternal, child and children′s hospitals were collected to conduct this multi-center study on the analytical performance of 5 commonly used whole blood CRP detection systems from March to April in 2019. The blank check, carryover, repeatability, intermediate precision, linearity, sample stability, influence of hematocrit/triglyceride/bilirubin, comparison with SIEMENS specific protein analyzer and trueness were evaluated. The 5 systems included BC-5390CRP autohematology analyzer, AstepPLUS specific protein analyzer, Ottoman-1000 Automated Specific Protein POCT Workstation, i-CHROMA Immunofluorometer equipment Reader and Orion QuikRead go detecting instrument. The 5 systems were labeled as a, b, c, d and e randomly.Results:Within the 5 systems, all values of blank check were less than 1.00 mg/L, the carryovers were lower than 1.00%. The repeatability of different ranges of CRP concentrations including 3.00-10.00, 10.00-30.00 and>30.00 mg/L were less than 10.00%, 6.00% and 5.00%, respectively, and the intermediate precision was less than 10.00%. The linearity correlation coefficients of the 5 systems were all above 0.975, while the slope was within 0.950-1.050. Whole blood samples were stable within 72 hours both at room temperature (18-25 ℃) and refrigerated temperature (2-8 ℃). The CRP results were rarely influenced by high triglyceride or bilirubin, except for the immmunoturbidimetric test based on microparticles coated with anti-human CRP F(ab) 2 fragments. When triglyceride was less than 15.46 mmol/L, the deviation of CRP was less than 10.00%. When bilirubin was less than 345.47 μmol/L, the deviation of CRP was less than 10.00%. CRP was more susceptible to Hct on the systems without Hct correction. The deviation of CRP between different Hct dilution concentration and 40% dilution concentration can reach as high as 67.48%. The correlation coefficients ( r) of 5 systems were all more than 0.975 in the range of 0-300.00 mg/L compared with Siemens specific protein analyzer. All systems passed the trueness verification using the samples with specified values of 12.89 and 30.60 mg/L. Conclusion:The performance of 5 systems can basically meet the clinical needs, but it is suggested that the whole blood CRP detection system without automatic Hct correction should be modified manually.
