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.

Objective:To comprehensively evaluate the tricuspid valve, right heart anatomical characteristics and related dynamic parameters in patients with different degrees of functional tricuspid regurgitation (FTR) using four-dimensional auto tricuspid valve quantitative(4D Auto TVQ), four-dimensional auto right ventricle quantitative(4D Auto RVQ), and four-dimensional auto left atrium quantitative(4D Auto LAQ), and to investigate the structural and functional changes of the tricuspid valve and right heart in them.Methods:Sixty-three patients with FTR diagnosed by echocardiography at the First Affiliated Hospital of Guangxi Medical University from February to July 2022 were prospectively selected as the case group, including 30 patients with mild FTR and 33 patients with moderate or above FTR, and 30 healthy subjects were selected as the control group. Transthoracic echocardiography was used for two-dimensional and three-dimensional image acquisition of the heart. The tricuspid regurgitation volume, left ventricular ejection fraction (LVEF), right ventricular global strain (RVGS) were measured by 2D images, and pulmonary artery systolic pressure (PASP) were measured from the tricuspid regurgitation pressure difference. The 3D images were imported into EchoPAC 204 to obtain the tricuspid valve, right heart structure and related dynamic parameters. The annulus area (AA), annulus perimeter(AP), spherical index (SI), annulus area change fraction (AC), coaptation point height (CPH), and tenting volume (TV) were measured by 4D Auto TVQ. The right atrial maximum volume (RAVmax) and right atrial minimum volume (RAVmin) were measured by 4D Auto LAQ. Right ventricular end-diastolic volume (RVEDV), right ventricular end-systolic volume (RVESV), right ventricular fractional area change (RVFAC) and tricuspid annular plane systolic excursion (TAPSE) were measured by 4D Auto RVQ. After standardizing the dimension parameters with body surface area (BSA), the differences in the above parameters were compared between the three groups, the correlation between regurgitant volume and each parameter was compared by correlation analysis, and the independent factors of increased tricuspid regurgitant volume were investigated by univariate and multivariate linear regression analysis.Results:There were statistically significant differences in PASP, AA/BSA, AP/BSA, AC, TV, RAVmax/BSA, RAVmin/BSA, RVFAC, RVGS, and TAPSE between the three groups (all P<0.05). There were statistically significant differences in LVEF, CPH, RVEDV/BSA, and RVESV/BSA in the moderate and above FTR group compared with the control and mild FTR groups (all P<0.05). Correlation analysis showed that RAVmin was the most highly correlated with tricuspid regurgitant volume ( r=0.875, P<0.001) and TV and end-systolic annulus area(ESAA) were highly correlated with tricuspid regurgitant volume ( r=0.747, 0.683; both P<0.001) in patients with FTR. Multifactorial linear regression showed that RAVmin, TV and regurgitant volume were independently positively correlated (β=0.721, 0.205; both P<0.05). Conclusions:The four quantification technique can provide valid structural and functional information by quantifying the tricuspid valve as well as the right heart in patients with FTR, and RAVmin and TV are independent correlates of increased tricuspid regurgitant volume.

Objective　To provide a data foundation not only for food safety supervision and pollution source tracing, but also for the clinical treatment of drug-resistant bacteria in barreled drinking water, the drug resistance and type Ⅲ secretion system (T3SS) virulence genes carriage of Pseudomonas aeruginosa detected in barreled drinking water in Hainan Province were investigated, and the correlative relationship between strain ribosomal subtypes and virulence genes were then discussed. Methods The drug resistance of the isolated 55 strains of Pseudomonas aeruginosa was confirmed by using VITEK 2 Compact automatic microbial drug sensitivity system, and the T3SS virulence genes ExoU, ExoS, ExoT and ExoY were amplified by PCR, bacterial strain subtypes and homology were analyzed by the RiboPrinter automatic microbial gene fingerprint identification system. Results The drug sensitivity results showed that Pseudomonas aeruginosa isolated from barreled water had relatively low drug resistance, though one strain of multidrug-resistant Pseudomonas aeruginosa was discovered, resistant to imipenem, ciprofloxacin and cefepime. The distribution of T3SS virulence genes showed four genotypic combinations: ExoT+/ExoY+/ExoS+/ExoU- (45.45%, 25/55), ExoT+/ExoY+/ExoS-/ExoU+ (34.55%, 19/55), ExoT+/ExoY-/ExoS-/ExoU+(18.18%, 10/55), ExoT+/ExoY+/ExoS+/ExoU+ (1.82%, 1/55). Ribosomal typing results showed that the Pseudomonas aeruginosa strains were divided into six subtypes, the numbers of each subtype accounted for 24 (43.64%), 1 (1.82%), 25 (45.45%), 1 (1.82%), 3 (5.45%) and 1 (1.82%) respectively, with subtype Ⅰ and subtype Ⅲ being dominant. The main T3SS genotypes of the top two subtype I and subtype III were ExoT+/ExoY+/ExoS-/ExoU+ (16/24, 66.67%) and ExoT+/ExoY+/ExoS+/ExoU- (22/25, 88%). Conclusions The T3SS secretion system exhibits the characteristics of multiple virulence genes' coordinated expression, and there is a certain correlation between subtypes of bacterial strains and virulence genotypesThe exploration of the relationship between them provides guidance for tracing the source of Pseudomonas aeruginosa contamination, production control, clinical treatment in barrelled drinking water, and preliminarily establishes the initial data of local Pseudomonas aeruginosa strains in barrelled drinking water as well the related drug sensitivity data in Hainan.

Objective:To detective the cut-off values of amino acid levels in premature infants in Sichuan.Methods:Data of newborns screening for inherited metabolic diseases (IMD) by tandem mass spectrometry in Sichuan Province from January 2018 to December 2019 were retrospectively analyzed.They were divided into premature infant group ( n=2 264, 1 312 males and 952 females) and full-term infant group ( n=53 275, 28 269 males and 25 006 females). The cut-off values of amino acids in dry blood spots were expressed as percentage ( P0.5 - P99.5), and rank sum test was used for comparison between preterm and full-term infants.

Objective:To analyze the clinical characteristics, therapeutic options and risk factors of mortality in patients with carbapenem-resistant Acinetobacter baumannii (CRAB) bloodstream infection, and to provide evidence for clinical treatment option and prognosis evaluation of CRAB bloodstream infections. Methods:A retrospective study was carried out in 224 patients with confirmed diagnosis of CRAB bloodstream infection during the period from January 2012 to December 2017 in West China Hospital, Sichuan University. The patients were divided into the death group and the survival group according to the survival status 28 days after collecting blood samples. The clinical features and therapeutic options of antibacterial drugs were reviewed. Student′s t test was used for analyzing normally distributed data and Mann-Whitney U test for non-normal data.Chi-square test was used for categorical variables. Univariate and multivariate logistic analysis were used to analyze the risk factors of mortality associated with CRAB bloodstream infection. Results:Among 224 cases of CRAB bloodstream infection, 121 cases died (54.02%). These patients were mainly in intensive care unit (ICU) and hematology department. The common underlying diseases were severe acute pancreatitis and severe cardiovascular events. The interleukin (IL)-6 level (median (interquartile range)) in the death group (480.40 ng/L (1 432.95 ng/L)) was higher than that of the survival group (107.05 ng/L (263.08 ng/L)), the difference was statistically significant ( Z=4.526, P<0.01). The procalcitionin (PCT) levels in the death group and the survival group were 3.81 μg/L (17.26 μg/L) and 2.12 μg/L (12.74 μg/L), respectively, with no difference between the two groups ( P>0.05). The death rate of empirical treatment with a single or more non-active antimicrobial agents was 57.14% (64/112), that of monotherapy with active agent was 45.68% (37/81), and that of combination therapy with at least one active drug was 64.52% (20/31). The differences had no statistical significance ( P=0.130). The logistic regression analysis showed that the risk factors of mortality associated with CRAB bloodstream infection were renal dysfunction (odds ratio ( OR)=2.181, P=0.024) and multiple organ dysfunction syndrome (MODS; OR=20.376, P<0.01). Conclusions:The fatality rate of patients with CRAB bloodstream infection is high. These patients with renal dysfunction or MODS have poor prognosis. In addition to early effective antibacterial therapy, individual comprehensive treatment should be implemented in order to improve the curative effect.

Objective To acquire the basic information on diagnostic radiology and radiotherapy institutions and the frequency of medical radiation of Hebei province in 2016.Methods A survey was made using questionnaires for basic information on medical X-ray diagnosis,interventional radiology,radiotherapy and clinical nuclear medicine.Values of frequencies were derived for each type of medical X-ray procedure by dividing the total population.Results In 2016 there were 2 951 institutions at province level and 6 966 pieces of equipment involved in diagnostic radiology and radiotherapy treatments.Frequency values were estimated to be 379.25 examinations per 1 000 population in medical X-ay diagnosis,2.31 per 1 000 in interventional radiology,0.55 per 1 000 in radiotherapy and 1.65 per 1 000 in clinical nuclear medicine.The frequency for CT examination was 136.39 per 1 000,accounting for 36％ of the total frequencies in the province,with average annual growth rate of 12.4％.The highest value of frequency in clinical nuclear medicine was from Shijiazhuang among all types of medical procedures in different regions,11 times higher than the lowest value found in Hengshui city.Although the number of tertiary hospitals only accounted for 2.3％ of the total number of institutions,they contributed 25.5％,by examination number,of the medical X-ray diagnosis and 35.3％ of the CT examination.Interventional radiology and radiotherapy contributed more than 70％ of the total frequencies in the province,and clinical nuclear medicine was as high as 97.7％.Conclusions The basic information on diagnostic radiology and radiotherapy institutions and the frequency of medical procedures in Hebei in 2016 have been preliminarily made clear.Medical exposure could maintain a long-term growth trend.The frequency distribution of medical procedures in various regions and medical institutions is highly unbalanced.It is desirable to enhance the macroeconomic regulation and the management of medical radiation protection in order to rationally perform all types of diagnostic radiology and radiotherapy treatments to protect the health and safety of the patients and the examined individuals,and to promote the sustainable development of the health care services.
