The gait acquisition system can be used for gait analysis. The traditional wearable gait acquisition system will lead to large errors in gait parameters due to different wearing positions of sensors. The gait acquisition system based on marker method is expensive and needs to be used by combining with the force measurement system under the guidance of rehabilitation doctors. Due to the complex operation, it is inconvenient for clinical application. In this paper, a gait signal acquisition system that combines foot pressure detection and Azure Kinect system is designed. Fifteen subjects are organized to participate in gait test, and relevant data are collected. The calculation method of gait spatiotemporal parameters and joint angle parameters is proposed, and the consistency analysis and error analysis of the gait parameters of proposed system and camera marking method are carried out. The results show that the parameters obtained by the two systems have good consistency (Pearson correlation coefficient r ≥ 0.9, P < 0.05) and have small error (root mean square error of gait parameters is less than 0.1, root mean square error of joint angle parameters is less than 6). In conclusion, the gait acquisition system and its parameter extraction method proposed in this paper can provide reliable data acquisition results as a theoretical basis for gait feature analysis in clinical medicine.

Objective:To evaluate the minimally invasive fixation with a locking plate via the tarsal sinus approach in the surgical treatment of Sanders Ⅱ and Ⅲ calcaneal fractures.Methods:A retrospective study was conducted to analyze the 65 patients who had been surgically treated for Sanders Ⅱ and Ⅲ calcaneal fractures at Department of Foot and Ankle Surgery, Binzhou Medical College Hospital from April, 2019 to September, 2020. There are 44 males and 21 females with an age of (42.5±10.4) years, and 46 Sanders type Ⅱ fractures and 19 Sanders type Ⅲ ones. The patients were divided into group L and group S according to surgical methods. Group S of 35 cases was fixated with a minimally invasive locking plate through the tarsal sinus incision while group L of 30 cases fixated with a locking plate through the L-shaped incision. The 2 groups were compared in terms of waiting time before surgery, surgical time, hospital stay, intraoperative bleeding, visual analogue scale (VAS) at 3 days after surgery, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score at 1 year after surgery, excellent and good rate by the Maryland foot function score, B?hler angle, Gissane angle, varus angle, and complications.Results:There was no significant difference in the general data before surgery between the 2 groups, showing comparability ( P>0.05). All patients were followed up for (13.3±1.6) months after surgery. The waiting time before surgery [(2.8±1.8) d], surgical time [(80.7±9.9) min], hospital stay [(6.7±1.9) d], intraoperative bleeding [(54.3±14.2) mL], and VAS at 3 days after surgery [6 (5, 7) points] in group S were all significantly less or lower than those in group L [(8.2±2.8) d, (105.0±15.7) min, (14.6±3.4) d, (74.3±12.8) mL, and 7 (6, 8) points] (all P<0.05). At one year after surgery, the AOFAS ankle-hindfoot score [(90.1±3.5) points] in group S was significantly higher than that in group L [(83.5±6.7) points] ( P<0.05), but there was no statistically significant difference in the excellent and good rate by the Maryland foot function score between the 2 groups [91.4% (32/35) versus 86.7% (26/30)] ( P=0.695). The B?hler angle, Gissane angle, and varus angle were significantly improved in all patients one year after surgery compared with the values before surgery ( P<0.05), but there were no statistically significant differences within either group or between the 2 groups at 3 days or 1 year after surgery ( P>0.05). Peroneal muscle pain was reported in 1 case in group S; there were 2 cases of skin necrosis, 1 case of incision hematoma and 1 case of sural nerve injury in group L. Conclusion:The minimally invasive fixation with a locking plate via the tarsal sinus approach is an effective treatment for Sanders Ⅱ and Ⅲ calcaneal fractures.

OBJECTIVE:
To measure the concentration of bone morphogenetic protein 2 (BMP-2) in demineralized bone matrix (DBM) prepared from different long bones and to evaluate the osteoinductivity of different DBM on MC3T3-E1 cells.
METHODS:
Different bones from the same cadaver donor were used as the initial materials for making DBM, which were divided into ulna group (uDBM), humerus group (hDBM), tibia group (tDBM), and femur group (fDBM) according to the origins, and boiled DBM (cDBM) was taken as the control group. The proteins of DBM were extracted by guanidine hydrochloride, and the concentrations of BMP-2 were determined by ELISA assay. Then the DBM were co-cultured with MC3T3-E1 cells, the proliferation of MC3T3-E1 cells was observed by cell counting kit 8 (CCK-8) assay. The osteogenic differentiation ability of MC3T3-E1 cells was qualitatively observed by alizarin red, alkaline phosphatase (ALP), and Van Gieson staining, and the osteogenic differentiation ability of MC3T3-E1 cells was quantitatively analyzed by ALP content. Linear regression was used to analyze the effect of BMP-2 concentration in DBM on ALP synthesis.
RESULTS:
There were significant differences in the concentration of BMP-2 among the DBM groups (P<0.05). The concentrations of BMP-2 in the lower limb long bone were higher than those in the upper limb long bone, and the concentration of BMP-2 in the fDBM group was about 35.5 times that in the uDBM group. CCK-8 assay showed that the cells in each group continued to proliferate within 5 days of co-culture, and the absorbance (A) values at different time points were in the order of cDBM group

Objective:To understand the etiological characteristics of an acute gastroenteritis outbreak.Methods:Real-time polymerase chain reaction (PCR) and bacteria cultures were performed for the samples, including stool samples from patients and cooks, environmental swabs, raw food material (chicken meat), collected during the outbreak. Pulsed-field gel electrophoresis, antibiotics susceptibility test and whole-genome sequencing were performed for the Campylobacter jejuni isolates. Results:Four stool samples from patients were positive for Campylobacter jejuni by real-time PCR, in which 1 Campylobacter jejuni strain was isolated from a case who had no antibiotic treatment. Twelve Campylobacter jejuni and 7 Campylobacter coli isolates were obtained from 4 raw chicken meat samples. The Campylobacter jejuni strain isolated from the case was resistant to nalidixic acid, ciprofloxacin, chloramphenicol, florfenicol and tetracycline. The MLST analysis with the whole-genome sequences confirmed that the Campylobacter jejuni isolate from the case belonged to ST10075. Antimicrobial resistance genes cmeABCR, tetO/M and blaOXA-61 were found in the genome of the isolate from the patient by the whole-genome sequencing. No mutation in 23S rRNA was found and the C257T mutation in gyrA was identified in this isolate. Conclusion:Laboratory analysis indicated that Campylobacter jejuni infection might be the major cause of this gastroenteritis outbreak.

Objective To investigate the effect of continuous blood purification (CBP) on peripheral blood monocyte membrane CD14 (mCD14) expression and inflammatory response in patients with traumatic sepsis Methods A retrospective case control study was conducted on the clinical data of 50 patients with severe sepsis after trauma treated between January 2015 and December 2016. There were 34 males and 16 females, with an average age of 45.37 years (range, 16-73 years). Patients were divided into CBP group (25 cases) and non-CBP group (25 cases) according to whether they agreed to receive CBP treatment. The peripheral blood samples were collected at 0, 12, 24, 48, and 72 hours after treatment, and the mCD14 and leukocyte elastase (HLE) expressions were detected by flow cytometry and by ELISA, respectively. The peripheral blood mononuclear cells were isolated from the two groups 24 h after treatment and cultured in vitro. The variations of mCD14 expression in mononuclear cells were measured at 4, 8, 12, 24, 48, and 72 h after stimulation with lipopolysaccharide (LPS). The expression levels of tumor necrosis factor (TNF) -a, interleukin (IL) -6, and IL-10 in mononuclear cells were detected by ELISA. Results At 12, 24, 48, and 72 hours after treatment, the leukocyte elastase levels in the two groups were lower than those before treatment (P < 0.01), and the decrease in CBP group was significantly greater than that of non CBP group(P<0.01). At 12, 24, 48, and 72 hours after treatment, the mCD14 levels in both groups were up-regulated before treatment (P <0.01), and the increase in CBP group was significantly greater than that of non CBP group (P < 0.01). The mCD14 expressions before treatment, 4 h after treatment, and 8 h after treatment in CBP group were all higher than those in non CBP group at the same time points. At 4, 8, 12, 24, and 48 hours after the re-stimulation with LPS on the mononuclear cells in both groups, the levels of TNF-α and IL-6 in CBP group were significantly higher than those in non-CBP group (P <0.01), and there was no significant difference in IL-10 levels between the two groups (P >0.05). Conclusions CBP treatment can increase monocyte mCD14 expressions through eliminating inflammatory factors and pro-inflammatory mediators and reducing HLE directly or indirectly in patients with traumatic sepsis. When the body is stimulated again, its anti-inflammatory response ability is markedly stronger than that of patients who have not received CBP treatment.

Objective To identify the critical indicators of nursing practice environment in China, as a reference for related studies. Methods Descriptive systematic review was used to retrieve literature of nursing practice environment, collect all potential indicators and design questionnaires based on those indicators. In the end, 39 potential indicators were identified, for a questionnaire survey of nurses from cooperating medical institutions in 30 provinces in China, with the data subject to statistical analysis in multiple linear regression model. Results Questionnaire items of higher mean score were usually found with a smaller 95% confidence interval, while coefficient of variation tended to be lower. Seventeen indicators were recommended as key indicators for nursing practice environment in China, including proper working hours and intensity, opportunities for nurses to participate in hospital management, good working relationship with doctors within a department,nursing managers′support for nurses′right decisions. The remaining components turned out to be insignificant in the analysis. Conclusions The influencing factors for the nursing practice environment in China are different from other countries. In this consideration, nursing managers should further explore and focus on such special indicators, and proactively improve the quality of nursing practice environment for better nursing service.

Spontaneous bacterial peritonitis (SBP) is a common complication of cirrhosis. Based on our current understanding of SBP, the most common etiologies for SBP in cirrhosis are Enterobacter and Streptococcal species. Th e Aeromonas species are ubiquitous in fresh or sea water. Aeromonas caviae is never identified as etiology in cases of SBP. A patient, who had a history of liver cirrhosis related to chronic hepatitis B virus infection for 1 year, presented with diarrhea. He had diarrhea 1 week later returned from coastal city. He was hospitalized and treated with norfloxacin after 7 days of severe symptoms, including fever, abdominal distention, and diarrhea. Analysis of the ascitic specimen revealed a white-cell count of 4.42 × 109 cells/L with 88% neutrophils. Analysis of stool specimen showed a white-cell count of 60 cells per high-power field. Th e patient started the injection of cefriaxone at a dose of 4 g/d. However, the situation was not improved. Th ree days later, stool and ascitic fluid culture showed positive for Aeromonas caviae. Antibiotic susceptibility testing revealed that imipenem, meropenem, amikacin, and cefoperazone-sulbactam were highly sensitive to the Aeromonas caviae. However, the bacilli resisted to ceftriaxone, ceftazidime, ampicillin-sulbactam, levofloxacin, and sulfamethoxazole. Ceftriaxone was then switched to imipenem. The patient was fully recovered 14 days later. Aeromonas caviae is a rare pathogen of SBP in cirrhosis. It resists to third-generation of cephalosporin and fluroquinolone, which are of frequently used dependent on clinical experience. It needs a special attention.
