ObjectiveThis study aims to systematically analyze the blood-absorbed components and metabolic profiles of Xiebaisan（XBS） in normal and chronic bronchitis （CB） mice using ultra performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry（UPLC-Q-Exactive Orbitrap MS）， while comparing differences between the two states. MethodsThirty female BABL/c mice were randomly divided into the normal group， the normal drug administration group， the CB group， the CB drug administration group and the dexamethasone group， with 6 mice in each group. The CB mouse model was established by inducing with ovalbumin （OVA）. The mice in the normal drug administration group and the CB drug administration group started to be gavaged with XBS（13.2 g·kg^-1） from the 21^st day， and the dexamethasone group mice were simultaneously gavaged with dexamethasone （0.5 mg·kg^-1） until the end of the 35^th day of the experiment. Subsequently， serum samples were collected and evaluated for their efficacy， based on the pharmacological evaluation indicators， to determine the efficacy of XBS in treating CB. Then the UPLC-Q-Exactive Orbitrap MS was employed to identify and analyze the chemical constituents， blood-absorbed components， and metabolites of XBS. Chemometric analysis was conducted to reveal metabolic profile differences under "dual states". Concurrently， Real-time PCR technology was utilized to detect the expression levels of key liver metabolic enzymes CYP2E1， CYP3A1， UGT1A1， and UGT1A6. ResultsA total of 28 prototype components and 158 metabolites （including 48 phase Ⅰ metabolites and 110 phase Ⅱ metabolites） of XBS were unambiguously identified in the serum of normal mice. Additionally， a comprehensive characterization was performed on a total of 32 prototype components and 178 metabolites （including 50 phase Ⅰ metabolites and 128 phase Ⅱ metabolites） of XBS in the serum of CB mice. Among them， 27 prototype components were detected in both states， including 12 flavonoids， 2 alkaloids， 3 triterpenes， 4 organic acids， 3 amides， 1 stilbene and 2 other compounds. The chemometrics analysis revealed no significant difference in the prototype components and metabolites of XBS between normal and CB mice； however， there was a significant increase in the in-vivo exposure of XBS in CB mice. Compared to normal mice， the levels of phase Ⅰ metabolites such as oxidation， reduction and methylation of blood components of XBS as well as phase Ⅱ metabolites of glucuronidation showed significant changes in CB mice. Real-time PCR further confirmed that these alterations were attributed to the upregulation of CYP2E1 （P<0.05）， CYP3A1 （P>0.05）， UGT1A1 （P<0.01） and UGT1A6 （P<0.01） enzymes expression in the liver of CB mice. ConclusionThis study elucidated the disparities in the levels of the blood-absorbed components and metabolic profiles of XBS in normal and CB mice， especially in oxidation， reduction， methylation in phase Ⅰ metabolism and glucoaldehyde acidification in phase Ⅱ metabolism. And there are related to the differences in the expression levels of phase Ⅰ and phase Ⅱ metabolic enzymes CYP2E1， CYP3A1， UGT1A1 and UGT1A6 in the liver.

BACKGROUND:Inter-limb asymmetry is a common phenomenon observed during human growth and development.Prolonged specialized training can lead to specific adaptations in inter-limb asymmetry among athletes.OBJECTIVE:To review the formation causes,manifestations,and impacts of inter-limb asymmetry on sports performance,and provide an overview of the relevant assessment methods and intervention strategies.METHODS:A literature search was conducted in the CNKI,WanFang,PubMed,and Web of Science databases from their inception to September 2024.The search terms included"asymmetry,asymmetries,asymmetric,asymmetrical,imbalance,strength,power,force,jump,sprint,athletic performance,anthropometry,injury"in English and Chinese.After excluding duplicate publications,irrelevant content,and conference papers,a total of 131 articles were finally included for analysis.RESULTS AND CONCLUSION:(1)Inter-limb asymmetry can be influenced by various factors including genetics,task demands,training regimens,injuries,fatigue,and limb preference.These factors lead to being primarily manifested in anatomical structure,strength performance,and task-specific asymmetry.(2)An increase in inter-limb asymmetry can result in impaired performance in bilateral in-phase symmetric movements.However,the relationship between increased inter-limb asymmetry and bilateral out-of-phase symmetric movements remains unclear and requires further investigation.(3)Training interventions have been shown to effectively mitigate inter-limb asymmetry,with unilateral training demonstrating superior outcomes compared with bilateral training.The choice of training methods and content should be tailored to meet the specific demands of the sport.(4)To further clarify the relationship between inter-limb asymmetry and athletic performance,it is recommended that future research adopt the concept of"task specificity"in inter-limb asymmetry.This includes standardizing study designs,selecting sensitive testing methods and indicators,unifying calculation methods to provide more high-quality evidence,and establishing categorized warning threshold standards for inter-limb asymmetry in different sports.

AIM: To investigate the correlation between different severity grades of obstructive sleep apnea-hypopnea syndrome(OSAHS)and visual field defects as well asvisual evoked potential(VEP)parameters in patients with anterior ischemic optic neuropathy(AION). METHODS: A retrospective case-control study. Patients diagnosed with AION complicated by OSAHS at the Department of Ophthalmology, the Affiliated Xuzhou Municipal Hospital of Xuzhou Medical University, between June 2022 and October 2025 were selected as the study subjects. According to the AHI and mSaO2, the patients were divided into three groups: a mild group(AHI 5-15 events/h, mSaO2 85%-90%), moderate group(AHI 16-30 events/h, mSaO2 80%-85%), and severe group(AHI >30 events/h, mSaO2 <80%). General demographic data, retinal nerve fiber layer(RNFL)thickness, visual field defect indicators including mean defect(MD)and pattern standard deviation(PSD), as well as VEP parameters(P100 latency and amplitude)were compared among the three groups. RESULTS: This study included a total of 110 patients with AION complicated by OSAHS. Based on the severity of OSAHS, the patients were divided into a mild group of 37 patients(21 men and 16 women, mean age 62.15±9.37 y), a moderate group of 35 patients(20 men, 15 women; mean age 61.82±8.94 y), and a severe group of 38 patients(22 men, 16 women; mean age 63.02±9.61 y). There were no significant differences among the three groups in terms of age, sex, TG, TC, LDL-C, HDL-C levels, or AION severity(all P>0.05); however, there were significant differences in history of hypertension, history of diabetes, systolic blood pressure, diastolic blood pressure, and FPG levels(all P<0.05). The mean RNFL thickness in the severe group(63.27±5.58 μm)was significantly lower than that in the moderate group(74.14±6.28 μm)and the mild group(83.22±7.02 μm), and the moderate group was lower than the mild group(all P<0.05); The MD value(-11.57±1.82 dB)and PSD value(7.35±0.87 dB)in the severe group were both higher than those in the moderate group [(-7.62±1.31 dB),(4.89±0.62 dB)] and the mild group [(-4.38±1.05 dB),(2.57±0.45 dB)](all P<0.05); the P100 latency in the severe group(132.41±8.57 ms)was longer than that in the moderate group(118.75±7.32 ms)and the mild group(105.62±6.14 ms), and the amplitude(7.65±1.53 μV)was lower than that of the moderate group(11.24±1.89 μV)and the mild group(15.38±2.11 μV)(all P<0.05). Spearman's correlation analysis revealed that the severity of OSAHS was negatively correlated with the MD value(rs=-0.901, P<0.05)and positively correlated with the PSD value and P100 latency(rs=0.947, 0.807, P<0.05), and was negatively correlated with P100 amplitude(rs=-0.878, P<0.05). CONCLUSION:The severity of OSAHS is closely associated with RNFL thickness, visual field defects, and VEP parameters in patients with AION; the more severe the OSAHS, the more pronounced the structural and functional damage to the optic nerve. Monitoring AHI and mSaO2 can aid in assessing the condition of patients with AION and developing personalized intervention plans.

ObjectiveTo analyze scarlet fever surveillance data in Harbin City from 2010 to 2024, to preliminarily understand its incidence level and epidemiological characteristics, and to provide a scientific basis for the further formulation of effective prevention and control strategies. MethodsScarlet fever surveillance data for Harbin City from January 1, 2010 to December 31, 2024 were collected through the China Disease Prevention and Control Information System. Descriptive epidemiological analyses were conducted using incidence rates and constituent ratios. ResultsFrom 2010 to 2024, a total of 11 052 scarlet fever cases were reported in Harbin City, during the 15-year period, with an average annual reported incidence of 7.65/100 000. The overall annual incidence rate showed a fluctuating downward trend, with epidemic peaks occurring from April to July each year and from November to January of the following year. The age group of 0 to 9 years had the highest incidence rate at 6.47/100 000. The majority of cases were students (4 707 cases, 42.59%), children in nurseries and kindergartens(3 289 cases, 29.76%) and scattered children (2 941 cases, 26.61%), together accounting for 98.96% of all cases. The incidence ratio of male to female was 1.53∶1. The average annual incidence rate was 9.23/100 000 for males and 6.07/100 000 for females. Over the 15-year period, all 18 districts (counties) in Harbin City had reported cases. The top five areas with the highest average annual reported incidence of scarlet fever were Acheng District (14.45/100 000), Xiangfang District (12.73/100 000), Pingfang District (12.10/100 000), Bin County (10.29/100 000) and Daowai District (10.08/100 000). ConclusionFrom 2010 to 2024, the overall incidence of scarlet fever in Harbin City presented a downward trend. The disease prevailed mainly in spring-summer and autumn-winter, rather than year-round, with cases concentrated in densely populated districts and counties. Children and adolescents constituted the major affected population. The incidence was slightly higher in males, and school-age children accounted for a larger proportion than other age groups. Comprehensive preventive measures should focus on health education in key endemic areas, strengthen targeted protection for high-risk groups, and enhance epidemic surveillance and early warning.

Objective:To construct an integrated early rehabilitation program for healthcare and rehabilitation system based on the information-motivation-behavioral skills (IMB) model and evaluate its application effect in patients treated with total hip arthroplasty (THA).Methods:Construction of the rehabilitation program: An integrated research team was established, composed of head burse of orthopedics, orthopedic nursing specialists, orthopedic surgeons, anesthesiologists, and rehabilitation therapists. Considering the key points of perioperative early rehabilitation of THA patients, an integrated early rehabilitation program was constructed based on the IMB model through literature review and expert panel method. Clinical application of the rehabilitation program: A retrospective cohort study was conducted to analyze the clinical data of 100 THA patients admitted to Qingdao Municipal Hospital from March to December 2023, including 47 males and 53 females, aged 60-85 years [(69.8±5.5)years]. Patients were divided into two groups according to their admission time: 50 patients admitted from March to July 2023, receiving routine care (routine care group) and 50 admitted from August to December 2023, receiving intervention through an early rehabilitation program of an integrated healthcare and rehabilitation system based on routine care (integrated care group). The first postoperative ambulation time and length of hospital stay were compared between the two groups. The Harris hip function score was used to assess hip function in both groups at 3 days, 1, 3, and 6 months postoperatively; the Barthel index was used to assess the daily living self-care capacity in both groups preoperatively, at 1, 3, and 6 months postoperatively. The incidence of complications within 6 months after surgery was compared between the two groups.Results:An early integrated rehabilitation program based on the IMB model comprised 25 specific measures of three domains: information support, motivational intervention, and behavioral skills. All the patients were followed up for 6 months. The first postoperative ambulation time and length of hospital stay in the integrated care group were (1.3±0.5)days and (7.4±2.3)days, shorter than (1.5±0.5)days and (8.5±2.3)days in the routine care group ( P<0.05). There were no statistically significant differences in the Harris hip function scores at 3 days postoperatively or preoperative Barthel index between the two groups ( P>0.05). At 1, 3, and 6 months postoperatively, the Harris hip function scores in the integrated care group were (80.3±6.0)points, (88.6±5.2)points, and (92.5±4.1)points, respectively, higher than (75.1±6.3)points, (84.2±5.7)points, and (88.0±5.2)points in the routine care group ( P<0.01); the Barthel index in the integrated care group were (79.2±8.7)points, (87.7±5.7)points, and (92.3±4.9)points, respectively, higher than (72.1±9.0)points, (83.5±6.6)points, and (88.6±5.0)points in the routine care group ( P<0.01). At 6 months postoperatively, the incidence of complications in the integrated care group was 4% (2/50), lower than 16% (8/50) in the routine care group ( P<0.05). Conclusion:Compared with the routine care, an integrated early rehabilitation program for medical care and health based on the information-motivation-behavioral skills model for THA patients can shorten the first postoperative ambulation time and length of hospital stay, restore hip joint function, improve daily living self-care capacity and reduce the incidence of complications.

Objective:This study aimed to analyze the genetic subtypes and drug resistance transmission characteristics of HIV-1 among the preoperative population in Ningxia from 2018 to 2023, to provide a scientific basis for the prevention and control of the AIDS epidemic.Methods:Plasma samples and demographic information of HIV/AIDS patients receiving antiviral treatment in Ningxia from 2018 to 2023 were collected. Blood samples with a viral loads >200 copies/ml from preoperative testing were amplified, sequenced, and subjected to genotypic resistance testing to analyze their genetic subtypes and drug resistance characteristics. The TN93 model in MEGA11 software was used to calculate the genetic distance between each pair of all sequences, and a molecular transmission network was constructed in Cytoscape 3.10.0 with 1.9% as the genetic threshold.Results:Among 101 preoperative HIV/AIDS patients, CRF07_BC and CRF01_AE were the predominant subtypes. The majority were male (85.15%, 86/101), aged 41-60 years (45.54%, 46/101), residing in Yinchuan city (61.39%, 62/101), and infected via heterosexual transmission (71.29%, 72/101), with most cases being late-detected. Of 39 drug-resistant sequences, resistance to non-nucleoside reverse transcriptase inhibitors (NNRTIs) alone (18.81%, 19/101) and dual resistance to nucleoside reverse transcriptase inhibitors (NRTIs)-NNRTIs (13.86%, 14/101) were most common. Among 44 sequences forming 13 transmission clusters, nine clusters harbored drug-resistant mutations. Four subtypes entered the molecular network, primarily involving heterosexual transmission, individuals with junior high school education or below, and men aged≥50 years.Conclusions:From 2018 to 2023, the preoperative HIV/AIDS patients had diversified genetic subtypes, with higher rates of overall drug resistance and late detection, stronger drug resistance and higher mortality rate. Strengthening molecular epidemiological research and developing targeted screening strategies are critical to improve early detection and reduce transmission risks.

Objective To explore the reproductive health literacy of young female sailors,investigate the influence of long voyage on the health,and propose strategies on health education.Methods A total of 49 young female sailors were enrolled.Their healthy status was evaluated by annual medical records.The questionnaire survey was also conducted to evaluate general status related to reproductive health,knowledge pertaining to reproductive health,and health status after long voyage.Results Some female sailors had symptoms of thyroid diseases,such as hypothyroidism(32.65%),benign thyroid nodules(59.18%),and suspected papillary carcinoma(in one sailor,2.04%).Ultrasonography revealed breast nodules in 5 subjects(10.00%),mammary gland hyperplasia in 46 subjects(93.88%)and reproductive benign diseases in 6 subjects(12.24%).The physical and mental states significantly changed in the late stage of long voyage.The changes in work and living environment were the main factors affecting the emotional and psychological status in the long voyage.The discomfort in menstrual cycle piled up with the above-mentioned changes during a long voyage,and the menstruation significantly affected the duty of 36.73%of female sailors during a long voyage.Female sailors had little knowledge about the prevention and examination of breast cancer and thyroid cancer.Conclusion The living and work environment during a long voyage may affect the health of the thyroid,mammary gland and reproductive system of young female sailors.Active health education via online and offline ways is helpful to improve the health literacy and self-care of female sailors,subsequently enhancing the combat effectiveness.

With the popularization of 5G communication technology and the continuous upgrade of robot-assisted surgery system,telesurgery has developed rapidly.However,there are few of reports about this technique in single-port laparoscopic gynecological surgery.On April 19,2024,the surgeons at the Second Affiliated Hospital of Naval Medical University in Shanghai successfully implemented robot-assisted single-port laparoscopic bilateral adnexectomy for a patient who was admitted to the Naval Hospital of the Eastern Theater Command in Zhoushan,Zhejiang Province through 5G communication technology.The operation time was 90 min,intraoperative bleeding was 20 ml,and no intraoperative complications occurred.There were no adverse events caused by robots such as robot system failure and instrument failure,or adverse events caused by remote communication such as network interruption and network attack.Intraoperative user datagram protocol(UDP)real-time monitoring data showed an average delay of 108 ms(range,105-111 ms)and a packet loss rate of 0.04%.The surgeons had a slight sense of delay when the operation amplitude was too large.There was no obvious stalling which affected the process of the operation.The patient was able to move around on the first day after surgery,and the catheter was removed.No postoperative complications occurred.The patient was discharged from the hospital on the second day after surgery.Postoperative pathological results revealed left fallopian tube ovarian serous cystadenofibroma,fallopian tubal tissue;right fallopian tube ovarian,sent for examination as ovarian and fallopian tube tissue.There were no complaints of discomfort during reexamination one month after surgery,and the umbilical incision healed well.This case is an attempt of telesurgery in the field of gynecology,and provides experiences for the further development of this technique.

Objective To investigate the situation of HIV infection and epidemiological characteristics among voluntary blood donors and pre-transfusion patients in Yuxi prefecture between 2010 and 2021.Methods Da-te collected with the HIV/AIDS Case Reporting Cards and original record of blood station,HIV antibody positive rate,the demographic characteristics,and epidemiological data of blood donors and pre-transfusion patients,were analyzed accordingly,the related date were statistically analyzed.Results The HIV antibody positive ratio were 5.56? and 2.01? among pre-transfusion patients and voluntary blood donors(P<0.001),showing an downward trend year after year.The HIV-positive detection rate among blood donors aged<25 years was significantly higher at 3.72‰ compared to 1.60‰ for those aged≥25 years(P=0.003).Among HIV-positive blood recipients,the proportion of individuals aged 15-24 years(34.62%)was markedly higher than that among blood donors(1.96%),whereas no donors were aged≥50 years compared to 23.53%of recipients(P<0.001).Farmers showed a significantly higher HIV detection rate(3.18‰)than students(2.66‰)and other occupations(1.60‰)(P=0.041).Similarly,individuals with high school education or below showed a higher detection rate(2.52‰)than those with high school education or above(1.45‰)(P=0.045).Among HIV-positive cases,blood donors had a higher proportion of HIV-infected individuals(84.62%)versus AIDS cases(15.38%),whereas the recipients showed the opposite trend:41.18%HIV-infected versus 58.82%AIDS cases(P<0.001).Conclusion In recent years,the HIV positive detection rate in Yuxi area has shown a downward trend,but the occurrence of HIV in Yuxi area is characterized by youthfulness and low education.Among them,HIV infected individuals through same-sex contact account for an important reason for HIV infection.
