Chaihu Guizhi Ganjiangtang was first recorded in the Treatise on Cold Damage （Shang Han Lun）. This prescription is composed of Bupleuri Radix， Scutellariae Radix， Cinnamomi Ramulus， Zingiberis Rhizoma， Trichosanthis Radix， Ostreae Concha， and Glycyrrhizae Radix et Rhizoma. It has the effects of soothing Lesser Yang， warming the spleen， and stimulating the generation of body fluid. It is mainly used to treat digestive tract diseases such as chronic cholecystitis （CC）， irritable bowel syndrome， and non-alcoholic fatty liver disease. Dyspepsia caused by CC presents a variety of gastrointestinal symptoms such as abdominal pain， poor appetite， postprandial fullness， aversion to greasy food， soft stool， and bitter mouth， being a type of biliary dyspepsia. In modern medicine， dyspepsia caused by CC is mainly managed by medical treatment and surgical treatment. Internal medicine mainly focuses on reducing inflammation， promoting the function of gallbladder， resolving stones， alleviating spasms， and relieving the pain for CC， demonstrating definite short-term efficacy but suffering from single effects， high recurrence rate， and poor compliance. Although surgical treatment can cure cholecystitis， it is accompanied by the increased incidence of adverse events such as abdominal pain， diarrhea， and dyspepsia. Modern clinical studies have confirmed that Chaihu Guizhi Ganjiangtang can significantly alleviate the symptoms such as abdominal pain and dyspepsia of CC patients. Pharmacological studies have found that Chaihu Guizhi Ganjiangtang mainly contains active ingredients such as Bupleuri Radix saponins， baicalin， cinnamaldehyde， gingerol， Trichosanthis Radix polysaccharide， Ostreae Concha polysaccharide， and Glycyrrhizae Radix et Rhizoma total flavonoids. Chaihu Guizhi Ganjiangtang can ameliorate the symptoms of dyspepsia caused by CC by inhibiting inflammatory responses， improving gallbladder contraction and gastrointestinal motility， regulating the bile acid-intestinal flora axis and the brain-gut axis， and modulating blood lipids through multiple targets. By reviewing the previous literature， this article summarizes the research progress in the treatment of dyspepsia caused by CC with Chaihu Guizhi Ganjiangtang and its main active ingredients as well as the pathogenesis of this disease and puts forward the shortcomings and improvement strategies for the current research. The review aims to provide a reference for the further research on Chaihu Guizhi Ganjiangtang in the treatment of dyspepsia caused by CC.

Objective To explore the number of peripheral blood regulatory T cells (Treg) in patients with chronic kidney disease (CKD) and its correlation with vascular calcification. Methods This was a single-center, cross-sectional, and observational study. Non-dialysis patients with CKD treated at Zhongshan Hospital, Fudan University from March 2021 to March 2022 were enrolled. Abdominal aortic calcification (AAC) was assessed using lateral abdominal X-ray. Number of Treg and cytokine levels were measured by flow cytometry. Logistic regression analysis was performed to evaluate the related factors for AAC in CKD patients. Results A total of 83 patients were included, aged 17–86 years, with 57 males (68.7%). The distribution of CKD stages was as follows: stage G1 in 7 patients (8.4%), stage G2 in 17 patients (20.5%), stage G3 in 21 patients (25.3%), stage G4 in 19 patients (22.9%), and stage G5 in 19 patients (22.9%). No AAC was observed in patients with stages G1 and G2, while the prevalence of AAC in patients with stages G3, G4, and G5 was 23.8%, 21.1%, and 26.3%, respectively. Compared with stage G1 patients, those with stages G3–5 showed decreased number of peripheral blood Treg and elevated levels of interleukin (IL)-6 and IL-17F (P＜0.05). The area under the receiver operating characteristic curve for number of peripheral blood Treg in predicting AAC in CKD patients was 0.766 (95%CI 0.652–0.879, P＝0.002). Logistic regression analysis showed that decreased number of Treg was related factor for AAC in CKD patients (OR＝0.957, 95%CI 0.922–0.992, P＝0.018). Conclusion As CKD progresses, number of peripheral blood Treg significantly decreases, which is correlated with AAC in CKD patients.

Objective:To develop and validate the Pain nursing Competency Evaluation Questionnaire for Nursing Students to provide an effective tool for measuring the pain management competency of nursing students in China.Methods:The questionnaire was constructed through literature review, semi-structured interviews, focus group discussions, Delphi expert consultation, and a pre-survey. From September 2023 to January 2024, a convenience sampling method was used to select 250 nursing students from Hangzhou Normal University and Lishui University in Zhejiang Province for the survey. Reliability and validity of the developed questionnaire were tested. A random sample of 30 nursing students was selected for retesting after two weeks.Results:A total of 10 female experts were consulted through correspondence. The Pain Care Competency Evaluation Questionnaire for nursing students consists of 36 items. Through exploratory factor analysis, five common factors were extracted: pain health education, comprehensive pain assessment, pain screening and assessment, analgesic interventions, and analgesic side effects nursing, which together explained 61.695% of the variance. The content validity of the questionnaire was 0.96, and the item-level content validity index ranged from 0.900 to 1.000. The overall Cronbach′s α coefficient was 0.924, and the Cronbach′s α coefficients for the five dimensions ranged from 0.856 to 0.915. The test-retest reliability was 0.831. Conclusions:The Pain Care Competency Evaluation Questionnaire for nursing students developed in this study has good reliability and validity. It can be used as a tool to assess nursing students′ competency in pain care and provides a reference for the design and optimization of pain care courses and clinical practice programs for nursing students in undergraduate institutions.

Objective:The Social Isolation Scale for people with type 2 diabetes mellitus (T2DM) was developed and tested for reliability and validity, which provided an effective tool for measuring the social isolation level of patients with T2DM.Methods:The initial scale was developed through literature review, qualitative interviews, and expert consultation. Convenience sampling method was used to select T2DM patients who met the inclusion and exclusion criteria for questionnaire survey. The item analysis method was used to select the items of the scale. Exploratory and confirmatory factor analyses were used to evaluate construct validity. The content validity of the scale was evaluated by the scale-level content validity index and the item-level content validity index. The criterion validity was verified by using the Lubben Social Network Scale-6 and the De Jong Gierveld Loneliness Scale. Reliability was tested through internal consistency and test-retest reliability.Results:Through literature review and qualitative interviews, 30 items of the scale were selected to form the first version scale. After two rounds of inquiries from 16 experts (expert authority coefficient = 0.897), the second version of the scale was formed. A total of 407 questionnaires were distributed in two stages using the second version scale. Among the 407 patients, there were 214 males and 193 females. Exploratory factor analysis extracted 4 common factors, with a cumulative variance contribution rate of 61.338%. The final scale was determined to include 4 dimensions and 16 items, with the dimensions being "social support network", "frequency of social participation", "satisfaction with interpersonal relationships", and "diabetes-related sense of isolation".The average content validity index at the scale level was 0.929, the content validity index at the item level was 0.830 - 1.000, and the criterion validity was - 0.647 and 0.681. The Cronbach′s α coefficient of the total scale was 0.822, and the test-retest reliability was 0.858.Conclusions:The Social Isolation Scale for people with T2DM has good reliability and validity. It is a reliable and valid tool for assessing social isolation in T2DM patients.

Objective Magnetic resonance angiography(MRA)offers a non-invasive and radiation-free advantage in detecting and diagnosing intracranial artery stenosis;however,it is associated with high equipment costs.Transcranial color-coded Duplex ultrasound(TCCD)combined with contrast-enhanced ultrasound(CEUS)presents advantages such as non-invasiveness,real-time dynamic monitoring,and low cost.Nevertheless,there were no reports comparing the sensitivity,specificity,diagnostic agreement with MRA,or health economic evaluation of TCCD combined with CEUS for detecting major intracranial artery stenosis.Methods From April 2023 to August 2024,a total of 55 patients suspected of having intracranial artery stenosis or occlusion were recruited at Beijing Tiantan Hospital,Capital Medical University.Both TCCD combined with CEUS and MRA were performed to evaluate the degree of stenosis in the terminal segment of the internal carotid artery,M1 and M2 segments of the middle cerebral artery,A1 and A2 segments of the anterior cerebral artery,P1 and P2 segments of the posterior cerebral artery,and the V4 segment of the vertebral artery.Intracranial artery stenosis was categorized into three groups:normal/mild,moderate,and severe/occlusion.Sensitivity,specificity,and consistency between the two methods were calculated.The Wilcoxon signed-rank test was used to compare the differences in examination costs and diagnostic time.Results Fifty-five high-risk patients(110 cerebral hemispheres in total)with suspected cerebrovascular stenosis were included(median age:46 years;69.0%male).TCCD combined with CEUS and MRA were performed simultaneously.TCCD combined with CEUS showed high sensitivity and specificity in diagnosing intracranial artery stenosis,with good consistency compared to MRA.The highest diagnostic consistency was observed in the M2 segment(Kappa=0.704)and A2 segment(Kappa=0.650),while the M1 segment showed moderate consistency(Kappa=0.569).The average cost of TCCD combined with CEUS was 240 CNY with a diagnostic duration of 21 min,compared to 722 CNY and 287 min for MRA(P<0.001,effect sizer=0.89-0.91).Conclusion Compared to MRA,TCCD combined with CEUS demonstrates higher consistency in screening for stenosis in the M2 segment of the middle cerebral artery and the A2 segment of the anterior cerebral artery.It is also more cost-effective.However,MRA has advantages in assessing deep intracranial vessels.A synergistic use of both methods can optimize the allocation of diagnostic resources for intracranial artery stenosis.It is recommended that primary healthcare institutions adopt TCCD as the initial screening tool,and,with standardized training and technical upgrades,combine it with CEUS.Complex cases should be referred for detailed evaluation by using MRA.

Aortic endovascular stent infection(AEI)is a rare and potentially fatal complication following endovas-cular aortic repair(EVER).Its occurrence involves multiple factors.Actively preventing the colonization and ad-hesion of pathogenic microorganisms on the stent can significantly reduce the incidence rate of AEI.The clini-cal manifestations of AEI are nonspecific.Patients who develop unexplained fever,fatigue,pain or elevated in-flammatory markers after EVER should be alerted to the possibility of AEI and require laboratory and imaging ex-aminations to be improved actively for further clarification.For patients diagnosed with AEI who can tolerate sur-gery,the preferred treatment is to thoroughly remove infected materials and tissues,and to reconstruct blood sup-ply and administer antibacterial therapy according to the patient's condition.For those who cannot tolerate surger-y,long-term or lifelong antibacterial drug therapy is required,which can be supplemented by percutaneous punc-ture drainage.Strict screening of EVER patients,active prevention of pathogen colonization,early diagnosis and multidisciplinary combination treatment can significantly reduce the incidence and fatality rate of AEI,there-by improving patient prognosis.

Objective To explore the effect of playing moderate-intensity table tennis and badminton on myo-pia prevention among children between 7 and 9 years old,so as to provide related theoretical basis.Methods A total of 536 myopic children were initially screened from two schools in Guangzhou via questionnaires and in-terviews.Among them,36 children(7-9 years old)were selected and randomly divided into a control group,a table tennis group and a badminton group,each of 12.All groups underwent 1.5-hour training three times a week for six months,covering training on dynamic visual acuity,sports vision and attention training and the ex-ercise intensity was adjusted according the heart rate,rating of perceived exertion(RPE)and blood oxygen lev-els.Moreover,the equivalent spherical degree(SED),ocular biology,and accommodative parameters were mea-sured before and after the intervention.Results After intervention,the left eye SEDs of the control and badmin-ton groups were lower than before intervention(P<0.05).Moreover,the axial length(AL)in the left and right eyes and the axial length/corneal radius of curvature(AL/CR)of all 3 groups after intervention were significant-ly higher than before that(P<0.05).The table tennis group showed significant improvement in accommodative fa-cility(AF)in both eyes(P<0.05),while the badminton group demonstrated significant increases in AF of both eyes,amplitude of accommodation(AMP)in the right eye,but a significant decrease in the positive relative adjustment(PRA)(P<0.05).Moreover,after intervention,SE and AF of both eyes in the table tennis group was significantly higher,with lower AL and AL/CR ratios in the left eye compared to the control group(P<0.05).The badminton group exhibited greater AMP in the right eye and AF improvements in both eyes com-pared to the control and table tennis groups(P<0.05),but lower PRA(P<0.05).Moreover,the left-eye SE of the badminton group was higher than the control group(P<0.05),while the right-eye corneal curvature and the left-eye AL/CR were lower than the latter(P<0.05).Meanwhile,after the intervention,the left-eye AL and PRA of the badminton group were significantly lower than the table tennis group(P<0.05).Conclusion Pupils can effectively increase their reserve of eye adjustment,improve the adjustment function of the eye,and delay the development of myopia by playing table tennis and badminton with moderate intensity.Playing table tennis excels in delaying refractive power changes,while doing badminton significantly improves PRA,AMP,and AF.

Objective:To investigate whether continued low-dose aspirin (LDA) intervention affects the incidence of pre-eclampsia (PE) and adverse pregnancy outcomes in pregnant women with high-risk PE screening in the first trimester and reassessed as low risk at 28 weeks of gestation.Methods:This study was a prospective observational cohort study. From April 2022 to April 2024, a total of 106 pregnant women who underwent prenatal examination in the Affiliated Jiangyin Hospital of Nantong University were enrolled. They were assessed as high risk of PE by multiple indicators combined screening at 11-13 +6 weeks of gestation, received LDA intervention, and were reassessed as low risk of PE at 28 weeks of gestation. The patients were divided into withdrawal group (49 cases) and continuation group (57 cases). The incidence of PE and adverse pregnancy outcomes were compared between the two groups. Results:(1) There were no statistically significant differences in general conditions and the incidence of pregnancy complications between the two groups (all P>0.05). During the PE risk screening at 11-13 +6 weeks of gestation, there were no statistically significant differences in mean arterial pressure (MAP) and ultrasound uterine artery pulsation index (UtPI) between the two groups (all P>0.05), but the placental growth factor (PlGF) level in the withdrawal group was significantly lower than that in the continuation group ( P=0.023). There was no significant difference in the proportion of pregnant women with high risk of PE before 32 weeks and 34 weeks of pregnancy between the two groups (all P>0.05). (2) There were 7 cases (14%, 7/49) of PE in the withdrawal group, including 1 case (2%, 1/49) of early-onset PE and 3 cases (6%, 3/49) of PE before 37 weeks of pregnancy. There were 11 cases (19%, 11/57) of PE in the continuation group, including 2 cases (4%, 2/57) of early-onset PE and 4 cases (7%, 4/57) of PE before 37 weeks of pregnancy. There were no significant differences in the incidence of PE (including early-onset PE and PE before 37 weeks of pregnancy), gestational hypertension, severe PE, chronic hypertension complicated with PE and chronic hypertension complicated with pregnancy between the two groups (all P>0.05). (3) There were no significant differences in cesarean section rate, preterm birth rate, placental abruption, postpartum hemorrhage, fetal growth restriction, fetal distress rate, neonatal birth weight, neonatal asphyxia, and 1-minute and 5-minute Apgar scores between the two groups (all P>0.05). No stillbirth occurred in the two groups. Conclusion:For pregnant women with high risk of PE screening in the first trimester and taking LDA intervention, there is no difference in the incidence of PE and adverse pregnancy outcomes whether to continue LDA or not after being reassessed as low risk at 28 weeks of gestation.

Objective To study how lipid bilayer fluidity modulates the interaction between β1 integrin and CD40L,as well as the formation of CD40L-mediated tumor cell contact interfaces.Methods Supported lipid bilayers(SLB)with different fluidities were prepared through adjusting the 1,2-dioleoyl-sn-glycero-3-[N-(5-amino-l-carboxypentyl)iminodiacetic acid]succinyl nickel salt(DGS-NTA)content.The functionalization of lipid bilayers was achieved by anchoring fluorescently labeled CD40L molecules onto the membrane surface.The contact interface formation of PC9 cells on the functionalized lipid bilayers was observed through confocal fluorescence imaging and fluorescence recovery after photobleaching(FRAP)experiments,and data of two dimensional(2D)reaction kinetics of β1 integrin and CD40L were extracted from Zhu-Golan plots.Results The diffusion coefficient of molecules in lipid bilayer was negatively correlated with DGS-NTA content.High fluidity of lipid bilayer promoted CD40L accumulation at cell contact interface and expanded the cell contact area.The 2D dissociation constants(2D Kd)of β1 integrin-CD40L complexes were approximately 13,31 and 65 molecules/μm2 for the three lipid bilayers with high,moderate and low fluidities,respectively.Conclusions High fluidity of lipid bilayers significantly facilitates diffusion and aggregation of CD40L to the cell contact interface,thus enhancing β1 integrin-CD40L interaction and the stability of cell contact interfaces.

Objective:To investigate the clinical characteristics and aeromedical assessment conclusions of bronchial asthma in military pilots.Methods:The clinical data of 24 military pilots was retrospectively analyzed who were diagnosed with bronchial asthma and hospitalized at the Air Force Medical Center between January 2010 and March 2024. These pilots were divided into a qualified group and a grounded group based on aeromedical assessment conclusions. The basic information, clinical data, diagnosis and treatment, and aeromedical assessment conclusions were compared between the 2 groups.Results:There were 11 military pilots in the qualified group and 13 in the grounded group. No statistically significant differences were observed between the 2 groups in terms of age at initial asthma diagnosis, body mass index, flying hours, aircraft types, smoking status, or family history of bronchial asthma (all P>0.05). The time intervals between the symptom onset, initial diagnosis and treatment and ground observation were shorter in the qualified group than in the grounded group, with statistically significant differences ( Z=-1.77, -2.73, P=0.047, 0.006). No statistically significant differences were found between the 2 groups in terms of cough variant asthma, concurrent allergic rhinitis, eosinophil count and percentage, and abnormal pulmonary function (all P>0.05). The proportion of military pilots with identified allergens was significantly higher in the grounded group than in the qualified group ( P=0.005). In the qualified group, one fighter pilot was aeromedically assessed as being restricted to dual-seat fighter aircraft. After 3 months of ground observation without disease recurrence, the dual-seat restriction was lifted. The other 2 fighter pilots were qualified for downgraded aircraft types (from fighters to bombers, transporters, or helicopters). Eight non-fighter pilots were aeromedically concluded as eligible for flight. After [43.0(15.8, 66.3)] months of treatment and ground observation, the 13 military pilots in the grounded group were found to be under poor symptom control with recurrent episodes before being grounded. Conclusions:Bronchial asthma in military pilots is closely related to allergic rhinitis, with early clinical symptoms often being atypical and prone to delayed diagnosis and treatment. Patients with bronchial asthma should receive individualized treatment based on their condition. Both the US military and the Chinese military stipulate that pilots with bronchial asthma be ineligible for flight. However, for cases with mild illness, no sudden acute severe attacks, symptom resolution after treatment, normal pulmonary function, and in stable condition after 3-6 months of ground observation, an aeromedical assessment can be conducted based on the aircraft types and flight duties.
