Foot ulcer prevention plays a crucial role in reducing the amputation rate among diabetic patients. With regard to the prevention of diabetic foot ulcers, the 2023 guidelines of the International Working Group of Diabetic Foot(IWGDF) were different from the 2019 counterpart. The most notable change is the addition of high-level evidence to support recommendations, primarily derived from randomized controlled studies. The 2023 guidelines also advocate for local skin temperature measurement, participation in ankle exercise training, and psychological intervention for foot ulcer prevention. This article conducts a comparative analysis of the two guidelines across six key dimensions: identification of high-risk feet, regular examination of high-risk feet, health education, ensuring appropriate daily footwear, addressing ulcer risk factors, and comprehensive foot care. Drawing from clinical insights, the application and prospective implications of the 2023 guidelines in China are also examined.

To analyze the biological characteristics of Pasteurella multocida in bovine respiratory tract and its prevalence in large-scale cattle farms,bacterial isolation,culture,and morphological observation were conducted on the lungs and liver samples of dead cows suffering from respiratory diseases in Hohhot,Inner Mongolia.The isolated strains were studied through biochemical testing,16S rRNA gene sequencing,specific primer PCR identification,capsule serotyping,pathogenicity testing,virulence gene testing,drug sensitivity testing,and drug resistance gene detection methods.The results showed that six strains of Pasteurella multocida serotype A were isolated and identi-fied from the lungs of diseased and dead cows.After sequencing the 16S rRNA sequence of the bac-teria,it was found that the six strains of Pasteurella multocida had the closest genetic relationship with the Chongqing isolate CQ2(CP033599.1).The results of mouse pathogenicity test and viru-lence gene detection showed that all isolates were pathogenic and carried at least 16 or more related virulence genes such as exbB,nanB,sodC,oma 87,etc.,but no hsf1 and toxA were detected.The results of drug sensitivity tests and resistance gene detection showed that the isolated strains were sensitive to different degrees of antibiotics such as ciprofloxacin,ofloxacin,and cefotaxime.They were resistant to streptomycin,clindamycin,and lincomycin,and resistance genes of str A,strB,and tet(H)were detected.The results indicate that there is a certain correlation between the pathoge-nicity and virulence genes,drug resistance phenotype,and drug resistance genes of Pasteurellamultocida type A in cattle.It is recommended to use quinolones(such as ciprofloxacin)and cepha-losporins(such as cefotaxime)antibacterial drugs in clinical practice,which can provide scientific basis and prevention and control plans for the prevention and treatment of respiratory diseases caused by Pasteurella multocida in cattle farms,and lay a foundation for the epidemiological mo-nitoring of bovine respiratory multocida pasteurellosis.

Objective:To translate the University of Rhode Island Change Assessment of voice scale（URICA-Voice） into Chinese and test its reliability and validity. Methods:The URICA-Voice scale was converted into Chinese by literal translation, cultural adjustment, expert consultation, pre-investigation, and back translation. Convenience sampling was used to recruit patients at four speech therapy centers from February to May 2022. Then the Chinese version of the scale was distributed to them, and the reliability and validity of the scale were tested after data collection. Cronbach ɑ was used to evaluate the reliability. The critical ratio method and Pearson correlation coefficient were used for item analysis. Item-level content validity, scale-level content validity, and confirmatory factor analysis were used to test the validity of the scale. Results:A total of 247 valid questionnaires were collected. ①Item analysis: the critical ratios between a high-score and low-score groups of 32 items were all statistically significant（P<0.01） and all the critical ratios were above 3.00. The Pearson correlation between 32 items and the total score was significant（P<0.01）. ②Validity analysis: I-CVI=1.00, S-CVI/Ave=1.00, χ²/df=2.30, RMSEA=0.07. Except for item 9 and 23, the standardized factor loading coefficients of other items were all above 0.50. AVE of the four dimensions of the scale was all above 0.50, and the combined reliability of the four dimensions was all above 0.70. The correlation coefficients between dimensions were less than the square root of the AVE of the dimension itself. ③Reliability analysis: the Cronbach ɑ of the whole scale was 0.94, and the Cronbach ɑ of the four dimensions were 0.88, 0.92, 0.94, and 0.88 respectively. Conclusion:The Chinese version of URICA-Voice has good reliability and validity, and can be used as a specific measurement tool for evaluating the compliance of voice training in China.

ObjectiveTo understand the current situation and influencing factors of health service demands of new residents in Shanghai. MethodsFrom July to August 2020， a questionnaire survey was conducted in 1 358 new residents from 36 survey points in 7 districts of the city. The questionnaire included the basic medical insurance coverage in the inflow area， the current situation of medical demand and related influencing factors， and the demands for other health services. Results47.1%（562/1 194）of new residents did not choose to seek timely medical treatment when they were not feeling well. The main reason was that the working hours occupied the medical treatment time. Logistic regression analysis showed that the main factors affecting the medical needs in new residents were the average daily working hours， living area and type of residence， health status， physical examination and physical exercise， and the type of basic medical insurance. The demands of new residents for "health consultation of common diseases and frequently occurring diseases"， "health behavior intervention （such as smoking cessation and alcohol restriction）"， "medical guidance and publicity"， "accidental injury prevention （traffic， work， falling， etc.）" and "maintenance of legitimate rights and interests of health" were 57.1%（682/1 194）、41.3%（493/1 194）、34.9%（417/1 194）、32.2%（385/1 194） and 31.9%（381/1 194）， respectively. ConclusionNew residents demands for medical services cannot be met. We should actively improve the working and living conditions of new residents， improve the construction of new residents' health service system， and improve the utilization level of health services.

Objective: To explore the promotion effect of laparoscopic standardized surgery for gastric cancer observational in some regional medical centers in Shanghai. Methods: A retrospective cohort study was carried out. Eleven regional medical centers in Shanghai received the promotion program of laparoscopic standardized surgery for gastric cancer, which was led by Ruijin Hospital, Shanghai Jiaotong University School of Medicine (Shanghai Minimally Invasive Surgery Center) from January to December 2020. Clinicopathological data of gastric cancer patients treated at these 11 regional medical centers before and after the promotion program were collected. Inclusion criteria were as follows: patients undergoing laparoscopic distal gastrectomy or total gastrectomy; gastric cancer confirmed by pathology; without distant metastasis or peritoneal metastasis. Patients who did not undergo laparoscopic D2 radical resection, or received neoadjuvant chemotherapy before surgery, or without complete clinical data were excluded. Patients undergoing laparoscopic surgery from January to December 2019 were included in the pre-promotion group (46 cases). Patients undergoing laparoscopic surgery from January to December 2021 were included in the post-promotion group (102 cases). In addition, patients undergoing laparoscopic surgery at Ruijin Hospital from January 2021 to December were included in the control group (138 cases). The baseline data, perioperative measurements postoperative complications, and pathological results of the three groups were analyzed and compared. Results: There were no significant differences in baseline characteristics among the three groups (all P>0.05). Compared with the pre-promotion group, the operation time in post-promotion group was significantly shorter [(207.3±36.0) minutes vs. (254.2±47.1) minutes, t=7.038,P<0.001], and the number of harvested lymph node was significantly more (24.4±12.2 vs. 18.9±5.5, t=2.900, P=0.004). However, there were no significant differences in the extent of resection, time to fluid intake, and postoperative hospital stay between the two groups (all P>0.05). Compared with the control group, the operation time [(207.3±36.0) minutes vs (172.6±26.0) minutes, t=8.281, P<0.001], time to fluid intake [(6.3±3.2) days than (5.5±3.0) days, t=2.029, P=0.044], and the postoperative hospital stay [(14.3±5.6) days vs. (10.1±4.8) days, t=6.036, P<0.001] in the post- promotion group were still longer. Total gastrectomy was less common in the post-promotion group compared with the control group [18 cases (17.6%) vs. 41 cases (29.7%), χ²=7.380, P=0.007]. However, there was no significant difference in the number of harvested lymph node between the two groups (P>0.05). The morbidity of postoperative complication in the post-promotion group (9.8%, 10/102) was significantly lower than that in the pre-promotion group (23.9%, 11/46) (χ²=5.183, P=0.023), while above morbidity was not significantly different between the post-promotion group and the control group [9.8% vs. 6.5% (9/138), χ²=0.867, P=0.352]. Conclusion: After the promotion of laparoscopic standardized surgery for gastric cancer in regional medical centers, the standardization degree of surgery has been improved, and the morbidity of postoperative complication decreases. Laparoscopic standardized surgery for gastric cancer can be promoted to more regional medical centers.

The prevalence of lower digestive tract diseases is high. White light endoscopy, narrow-band imaging (NBI) and blue laser imaging (BLI) are commonly used in the diagnosis of lower digestive tract diseases, but they have some limitation in the detection of small and atypical lesions. In recent years, linked color imaging (LCI), as a unique image-enhanced endoscopic technique, has shown its unique advantages in the detection of lower digestive tract diseases, the judgment of pathological classification of colorectal polyps, and the assisted endoscopic treatment of intestinal lesions. This article reviewed the research progress of LCI in endoscopic diagnosis of lower digestive tract diseases.

Upper digestive tract diseases include Barrett's esophagus, esophageal squamous cell carcinoma, Helicobacter pylori infection, gastric cancer, etc. Although white light imaging, blue laser imaging and narrow-band imaging have a certain ability to identify these upper digestive tract lesions, however, there are still some missed diagnosis and misdiagnosis of early lesions. Linked color imaging (LCI) could improve the diagnostic accuracy and sensitivity of upper digestive tract lesions through the unique color enhancement technology of endoscopic images. This article reviewed the research progress of LCI in endoscopic diagnosis of upper digestive tract lesions.

Objective:To investigate the efficacy and clinical experiences of fluorescein angiography assisted occlusion via lateral-orbital keyhole approach in internal carotid bifurcation aneurysms. Methods:The clinical data of 16 patients with internal carotid artery bifurcation aneurysms admitted to our hospital from January 2016 to December 2020 were retrospectively analyzed. All patients accepted fluorescein angiography assisted occlusion via lateral-orbital keyhole approach. The patients were followed up at one, 3, and 6 months after surgery by medical imaging. The therapeutic efficacy of these patients was assessed by Glasgow outcome scale (GOS). Results:All aneurysms in these 16 patients were clipped at one-stage operation. Intraoperative fluorescein angiography and FLOW 800 showed that the aneurysms were completely clipped without residual, and the blood flow of the parent artery and perforating arteries was unobstructed. Six months after surgery, 14 patients recovered well (GOS scores of 5), and 3 developed limb hemiplegia (GOS scores of 4).Conclusion:Intraoperative fluorescein angiography assisted occlusion via lateral-orbital keyhole approach is safe and effective in internal carotid bifurcation aneurysms.

Objective:To investigate the changes of distribution and antimicrobial resistance of pathogens in children with urinary tract infection in a single center in Beijing, and to provide references for the rational use of antibio-tics agent in clinical practice.Methods:The clinical data as well as urine culture and drug sensitivity results of children with urinary tract infection treated in the Department of Nephrology, Children′s Hospital Affiliated to Capital Institute of Pediatrics from January 2013 to May 2018 were retrospectively analyzed.According to the time of onset, the patients were divided into 2 groups, namely the 2013 to 2015 group and the 2016 to 2018 group.SPSS 17.0 software was used for statistical analysis of clinical data.Results:Among the 744 pathogenic bacteria isolated, the most common type was Gram-negative bacteria (59.4%, 442/744 strains), and the proportion of Escherichia coli ( E.coli) was the highest (39.4%, 293/744 strains). Gram-positive bacteria were the second most common (36.8%, 274/744 strains), among which, Enterococcus faecium (21.8%, 162/744 strains) accounted for the largest proportion (3.8%, 28/744 strains). Fungi were the least common type of pathogenic bacteria (3.8%, 28/744 strains). In Gram-negative bacteria, E.coli was highly resistant to Ampicillin (87.6%, 255/291 strains), but less resistant to Piperacillin/Tazobactam (12.7%, 37/291 strains). By comparing the overall distribution of Gram-positive, Gram-negative and common pathogenic bacteria in 2013 to 2015 and 2016 to 2018, the infection rate of Gram-negative bacteria (63.8%, 55.5%)was always higher than that of Gram-positive bacteria(33.1%, 40.2%), but the infection rate of Gram-positive bacteria has shown an upward trend in recent years, and the differences were statistically significant ( χ2=4.080, P<0.05). Conclusions:The main pathogenic bacteria of urinary tract infection in children are Gram-negative bacteria, and E.coli is the most common causative bacteria.However, the infection rate of Gram-positive bacteria has been increasing in recent years. E.coli is highly sensitive to Piperacillin and Tazobactam, which can be used as the adequate selection for treating urinary tract infection in children. E.coli is highly resistant to the first and the second-generation cephalosporin antibiotics, but sensitive to the third-generation cephalosporin antibiotics, such as Cefotetan.
