Abstract： Objective　To analyze the characteristics and corresponding drug resistance of pathogenic bacterial spectrum in eight major infection sites of hospitalized patients, and to provide epidemiological data for the rational selection of antibiotics in clinical practice. Methods　A total of 396 bacterial strains isolated from clinical specimens of hospitalized patients in member institutions of the Hainan Provincial Bacterial Resistance Monitoring Network from September 1, 2020, to September 30, 2022, were included in this study. Data were screened and filtered from the database of MH120 Microbial Identification and Drug Sensitivity Analysis System based on the technical scheme of the National Bacterial Drug Resistance Surveillance Network and Science and Technology Basic Resources Investigation Project research plan in 2020. The testing data were integrated, summarized, and analyzed using EXCEL and WHONET 5.6 software, and statistical analysis was conducted using SPSS 26.0 software. Results　Among of 396 strains of bacteria, 78 (19.7%) were isolated from respiratory tract specimens, 74 (18.7%) from urinary tract specimens, 72 (18.2%) from blood specimens, 54 (13.6%) from abdominal cavity specimens, 48 (12.1%) from skin and soft tissue specimens 48 strains (12.1%), 30 (7.6%) from reproductive tract specimens, 22 (5.6%) from central nervous system specimens, 18 (4.5%) from digestive tract specimens. Gram-negative bacteria accounted for 69.4% of the isolates, while gram-positive bacteria accounted for 30.6%. The top five gram-negative bacteria isolated were Klebsiella pneumoniae (14.9%), Escherichia coli (14.4%), Pseudomonas aeruginosa (10.4%), Acinetobacter baumannii (5.3%), and Salmonella species (4.5%). The top five gram-positive bacteria were Staphylococcus aureus (11.1%), Streptococcus agalactis (7.8%), Enterococcus faecalis (3.0%), Enterococcus faecium (2.8%), and Streptococcus suis (1.8%). Respiratory failure and bloodstream infection were independent influencing factors of treatment response (P<0.01). The resistance rate of Escherichia coli to ampicillin was 81.4%, and the resistance rate of Staphylococcus aureus to gentamicin and levofloxacin were both below 7%. Conclusions　The pathogen spectra vary with different infection sites of patients, and rational selection of antibiotics based on drug susceptibility testing is crucial to shorten the treatment time of patients and avoid the unnecessary emergence of drug-resistant strains caused by drug abuse.

Objective:To explore the safety and effectiveness of medium-frequency electrotherapy for increasing the volume of the latissimus dorsi muscle.Methods:Fifteen adult New Zealand white rabbits were randomly divided into three groups, namely group A, group B, and group C, with 5 rabbits in each group. This was a self-control study, with the right latissimus dorsi muscle as the experimental group and the left latissimus dorsi muscle as the control group. The three groups corresponded to three different current intensity levels: 7.062 mA for group A (6th gear), 10.593 mA for group B (9th gear), and 14.124 mA for group C (12th gear). After the 12th, 24th, and 36th sessions of the experiment, ultrasonography was used to collect the thickness of the latissimus dorsi muscle. After the 36th electrostimulation, the latissimus dorsi muscle samples were collected to measure their in vivo muscle thickness and wet weight and were then sent for HE and MASSON staining.Results:After the 12th, 24th, and 36th electrostimulation sessions, ultrasonographic sampling in groups A and B showed an increase in the thickness of the right latissimus dorsi muscle compared to the left; for example, the thickness on the right of group B increased by 37.8%. The wet weight data collected after the 36th electrostimulation in groups A and B showed an increase in the right latissimus dorsi muscle compared to the left; for example, the wet weight on the right of group B increased by 5.04%.Conclusions:Different electrostimulation modes of medium-frequency therapy technology can induce muscle fiber thickening or atrophy. In this experiment, the 9th gear (10.593 mA) of medium-frequency therapy technology may be a suitable choice for inducing muscle fiber thickening, and the 12th gear (14.124 mA) may be a suitable choice for inducing skeletal muscle thinning.

To demonstrate the effect of AB serum on terminal erythroid differentiation ex vivo.
 Methods: After separation of CD34+ cells from cord blood, the cells were cultured and divided into a control group and an experimental group. The effects of AB serum were examined by the expressions of different markers (GPA, Band3 and α4-integrin) for erythroblast differentiation and enucleation by flow cytometry. 
 Results: The CD34+ cells were successfully differentiated to enucleated red blood cells. There were evident differences among the expressions of GPA, Band3 and α4-integrin between the 2 groups. The percentage of GPA positive cells in the experimental group was bigger than that in the control group in every time point. The expression of Band3 in the experimental group was higher than that in the control group. The expression of α4-integrin in the experimental group was lower than that in the control group. In addition, the enucleation rate in the experimental group was higher than that in the control group.
 Conclusion: AB serum can promote the cell differentiation and enucleation during terminal erythroid differentiation in vitro.
