[Objective] To explore the strategy of blood management in patients with massive transfusion in the frigid plateau region. [Methods] The treatment process of a patient with liver rupture in the frigid plateau region was analyzed, and the blood management strategy of the frigid plateau region was discussed in combination with the difficulties of blood transfusion and literature review. [Results] The preoperative complete blood count (CBC) test results of the patient were as follows: RBC 3.14×10¹²/L, Hb 10⁶ g/L, HCT 30.40%, PLT 115.00×10⁹/L; coagulation function: PT 18.9 s, FiB 1.31 g/L, DD > 6 μg/mL, FDP 25.86 μg/mL; ultrasound examination and imaging manifestations suggested liver contusion and laceration / intraparenchymal hematoma, splenic contusion and laceration, and massive blood accumulation in the abdominal cavity; it was estimated that the patient's blood loss was ≥ 2 000 mL, and massive blood transfusion was required during the operation; red blood cell components were timely transfused during the operation, and the blood component transfusion was guided according to the patient's CBC and coagulation function test results, providing strong support and guarantee for the successful treatment of the patient. The patient recovered well after the operation, and the CBC test results were as follows: RBC 4.32×10¹²/L, Hb 144 g/L, HCT 39.50%, PLT 329.00×10⁹/L; coagulation function: APTT 29.3 s, PT 12.1 s, FiB 2.728 g/L, DD>6 μg/mL, FDP 25.86 μg/mL. The patient was discharged after 20 days, and regular follow-up reexamination showed no abnormal results. [Conclusion] Individualized blood management strategy should comprehensively consider the patient’s clinical symptoms, the degree of hemoglobin decline, dynamic coagulation test results and existing treatment conditions. Efficient and reasonable patient blood management strategies can effectively improve the clinical outcomes of massive transfusion patients in the frigid plateau region.

ObjectiveTo evaluate the therapeutic effect and mechanism of tendon-management and patella-movement therapeutic manipulation in the treatment of patellofemoral arthritis based on imaging evaluation. MethodsTotally 126 patients with patellofemoral arthritis were recruited and divided into a treatment group and a control group according to a randomised numerical table. The control group received routine sodium hyaluronate injection once a week for a total of 5 times； the treatment group received tendon-management and patella-movement therapeutic manipulation three times a week for four weeks. We compared the Western Ontario and McMaster University osteoarthritis index score （WOMAC）， visual analogue scale （VAS）， imaging indicators including patellar external displacement distance， patellofemoral fit angle， lateral patellofemoral angle， and patellofemoral index， and overall effectiveness evaluation between the two groups before and one week after treatment. ResultsThe total effective rate of the treatment group （45/54， 83.33%） was significantly higher than that of the control group （36/54， 66.67%，P＜0.05）. One week after the end of treatment， the VAS scores and WOMAC scores of both groups were lower than those before treatment in the same group （P＜0.01）， and the patellofemoral index and patellofemoral fit angle of the treatment group decreased compared with that of the control group （P＜0.05）. Compared with the pre-treatment， the distance of patellar external displacement， patellofemoral index， and patellofemoral fit angle decreased in the treatment group 1 week after the end of treatment， and the patellofemoral fit angle decreased in the control group （P＜0.05）. ConclusionThe therapeutic manipulation of tendon-management and patella-movement can correct the degree of patellar external displacement， alleviate joint pain symptoms， improve joint function， and achieve the goal of treating patellofemoral arthritis.

Objective To analyze the residual status,transfer behavior,and risk of paclobutrazole in the national mar-ket of Shenmai granules.Methods GC-MS/MS determined the residual amount of paclobutrazol in Shenmai granules,and ANOVA analyzed the distribution characteristics of sample residuals.The transfer rule of paclobutrazol from Ophiopogonis Radix to Shenmai granules was investigated by simulating the production process,and chronic exposure assessment was performed using the point evaluation model.Results The established method can accurately determine the residual amount of paclobutrazol in Shenmai granules.The residual amount of paclobutrazol in 85 batches of Shenmai granules ranged from 0.001 3 to 0.015 8 mg·kg-1,and there was a statistical difference in the residual amount among different enterprise samples.The transfer rate of paclobutrazol from decoction pieces to preparations was 29.8%.The chronic risk quotient(HQc)of paclobutrazol residues in Shenmai granules was 0.000 7%,far lower than 1.Conclusion There is a general presence of paclobutrazol residues in Shenmai granules.The risk assessment results show that the normal dosage of Shenmai granules does not pose an unacceptable risk to the general population.The residual distribution characteristics and process transfer rules can provide a reference for safety risk control in production enterprises.

OBJECTIVE: To identify phytochemical constituents present in the extract of flowers of Xanthoceras sorbifolia and evaluate their anti-oxidant and anti-hyperglycemic capacities. METHODS: The AlCl₃ colorimetric method and Prussian Blue assay were used to determine the contents of total flavonoids and total phenolic acids in extraction layers, and the bioactive layers was screened through anti - oxidative activity in vitro. The Waters ACQUITY UPLC system and a Waters ACQUITY UPLC BEH C₁₈ column (2.0 mm × 150 mm, 5 μm) were used to identify the ingredients. And anti-oxidative ingredients were screened by off-line UPLC-QTOF-MS/MS-free radical scavenging. The ameliorative role of it was further evaluated in a high-fat, streptozotocin-induced type 2 diabetic rat model and the study was carried out on NADPH oxidase (PDB ID: 2CDU) by molecular docking. RESULTS: Combined with the results of activity screening in vitro, the anti - oxidative part was identified as the ethyl acetate layer. A total of 24 chemical constituents were identified by liquid chromatography-mass spectrometry in the ethyl acetate layer and 13 main anti-oxidative active constituents were preliminarily screened out through off-line UPLC-QTOF-MS/MS-free radical scavenging. In vivo experiments showed that flowers of X. sorbifolia could significantly reduce the blood glucose level of diabetic mice and alleviate liver cell damage. Based on the results of docking analysis related to the identified phytocompounds and oxidase which involved in type 2 diabetes, quercetin 3-O-rutinoside, kaempferol-3-O-rhamnoside, isorhamnetin-3-O-glucoside, and isoquercitrin showed a better inhibitory profile. CONCLUSION The ethyl acetate layer was rich in flavonoids and phenolic acids and had significant anti-oxidant activity, which could prevent hyperglycemia. This observed activity profile suggested X. sorbifolia flowers as a promising new source of tea to develop alternative natural anti-diabetic products with a high safety margin.

Objective:To analyze the association between visceral fat area (VFA) and fatty liver based on quantitative CT (QCT) in people receiving health examination with normal body mass index (BMI).Methods:A cross-sectional study. A total of 1 305 physical examiners who underwent chest CT and QCT examination in the Department of Health Management of Henan Provincial People′s Hospital from January to December 2021 were retrospectively selected as subjects. The physical components at the central level of the lumbar two cone were measured with QCT, including subcutaneous fat area (SFA), VFA and liver fat content (LFC). And the metabolic indexes, such as blood lipids and blood glucose, were collected. The t-test and χ2 test were used to analyze the correlation between the detection rate of fatty live and LFCr and age and gender. According to level of VFA (<100 cm 2, 100-150 cm 2 and≥150 cm 2), the subjects were divided into three groups, and one-way ANOVA and χ2 test were used in comparison between groups. Multiple linear regression was used to analyze the correlation between VFA and metabolic indexes and LFC. Results:Of the 1 305 subjects, there were 634 males and 671 females. The detection rate of fatty liver in normal BMI population was 65.67%, and it was 72.71% and 59.02% respectively in men and women ( χ2=27.12, P<0.001), and the detection rate of fatty liver and LFC increased with age (both P<0.05). With the increase of VFA, the age, BMI, SFA, LFC, total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), fasting blood glucose (FBG), alanine aminotransferase (ALT), blood uric acid and prevalence of fatty liver increased (all P<0.05), and the low-density lipoprotein cholesterol (HDL-C) decreased ( P<0.001). Multiple linear regression analysis showed that after adjustment for age factors, regardless of male or female, LFC was independently positively related with VFA, BMI, and ALT (male β=0.206, 0.145, 0.174, female β=0.194, 0.150, 0.184; all P<0.05). FBG was positively correlated with male independently ( β=0.134; P<0.001). The indicators related to female independently were TC, TG, and blood uric acid ( β=-0.121, 0.145, 0.141, all P<0.05) Conclusion:In the population receiving health examination with normal BMI, the VFA measured by QCT technique is closely related to fatty liver.

Objective To explore the content and the psychometric properties of assessment tools used for evaluating functioning and adaptive behavior in school-age children with intellectual and developmental disabilities within educational settings. Methods The most used assessment tools included Vineland Adaptive Behavior Scales(VABS),Supports Intensity Scale for Children(SIS-C),Strengths and Difficulties Questionnaire(SDQ)and Repetitive Behavior Scale-Revised(RBS-R),for assessing functioning and adaptive behavior children with intellectual and developmental disabili-ties.Employing the framework and methods of the International Classification of Functioning,Disability,and Health(ICF),this research encoded and categorized the assessment dimensions and items of the four tools,and explored their psychometric properties. Results VABS's assessment content was solely focused on activities and participation,including speaking(d330),con-versation(d350),toileting(d530),eating(d550),drinking(d560),basic interpersonal interactions(d710),com-plex interpersonal interactions(d720),changing and maintaining body positions(d410-d429),carrying,moving and handing objects(d430-d449),and walking and moving(d450-d469).SIS-C assessed activities and participa-tion,and environmental factors,including washing oneself(d510),caring for body parts(d520),community life(d910),using transportation(d470),school education(d820),basic learning(d130-d159),looking after one's health(d570),basic interpersonal interactions(d710),and products and technology for education(e130).SDQ fo-cused on body functions,and activities and participation,including emotional functions(b152),global psychoso-cial functions(b122),attention functions(b140),and basic interpersonal interactions(d710).RBS-R focused on body functions,and activities and participation,including involuntary movement reaction functions(b755),invol-untary movement functions(b765),looking after one's health(d570),energy and drive functions(b130),under-taking a single task(d210),carrying out daily routine(d230),attention functions(b140),and handling stress and other psychological demands(d240).VABS was characterized by good specificity and excellent sensitivity.SIS-C demonstrated very good internal consistency,reliability and validity.SDQ was good in internal consistency,with excellent credibility and validity.RBS-R showed good internal consistency,reliability and validity. Conclusion SDQ and RBS-R cover both body functions,and activities and participation,SIS-C covers activity and par-ticipation,and environmental factors,while VABS solely assesses activities and participation.In terms of body functions,the assessment items primarily focus on mental functions(b130-b189)and movement functions(b750-b799).For activities and participation,the tools assess content across eight domains of functioning.Regarding en-vironmental factors,the assessment content mainly includes products and technology for education(e130),as well as design,construction and building products and technology of buildings for public use(e150).VABS,SIS-C,SDQ,and RBS-R are all norm-referenced measures,with moderate to excellent internal consistency,and good to excellent reliability and validity.

Objective To establish a UPLC-MS/MS method to measure the content of monoester-alkaloids(benzoylmesaconine,benzoylaconine,benzoylhypaconine)and diester-alkaloids(mesaconitine,hyp-aconitine,aconitine)in Fengshiantai tablets.To provide a basis for quality control by conducting chemometric analysis and risk assessment on the measurement results.Methods The components were separated on Waters BEH C18 column(2.1 mm×100 mm,1.7 μm)with methanol and 0.1%formicacid aqueous solution as the mobile phase by gradient elution at a flow rate of 0.3 mL·min-1.The column temperature was set at 35℃.The injection volume was 1 μL.The detection was carried out by electrospray ionization(ESI),and electron spray ionization source was adopted in positiveion detection with multiple reaction monitoring mode(MRM).Results Six components showed good linear relationships within their own ranges(r≥0.9990),whose average recovery rate of samples were 90.3%-107.6%with the RSD of 0.9%-1.8%.In 23 batches of tested samples,the diester-alkaloids contents ranged from 1.35 to 19.49 μg per tablet,which indicated low risk of drug safety;the monoester-alkaloids contents ranged from 20.17-99.55 μg per tablet.The results of chemometrics showed that 23 batches of samples were classify into four categories,and there were certain differences in sample quality among different production enterprises.Conclusion The established method is stable and reliable,and can be used for quality control of Fengshi Antai tablets.

Objective:To investigate the inhibitory effect of probiotics on cholesterol gallstone formation in mice fed a high-fat diet and its impact on leptin and intestinal flora.Methods:Forty 8-week-old female C57BL/6J SPF mice were obtained. After one week of adaptive feeding, the mice were randomly assigned to G-NS group ( n=10), G-Probiotics group ( n=10), L-NS group ( n=10), and L-Probiotics group ( n=10). The G-NS group and G-Probiotics group were fed with standard diet, while the L-NS group and L-Probiotics group received lithogenic diet. Additionally, the G-Probiotics group and L-Probiotics group received a probiotic solution (5×10 9 CFU/ml, 0.1 mL/10 g) by gavage, once daily for 8 weeks. The G-NS group and L-NS group received an equal volume of normal saline by gavage. After 8 weeks, the stone formation rate of mice was observed, the serum leptin, total cholesterol (TC) and low-density lipoprotein cholesterol (LDL) contents of mice were detected, feces were collected and DNA was extracted to analyze the diversity and abundance of intestinal flora in mice. Count data were presented as percentages, Fisher′s exact probability test was used for comparisons, and measurement data with normal distribution were presented as mean±standard divation ( ± s). One-way ANOVA was applied for inter-group comparisons, and the K-W rank sum test was utilized to analyze inter-group differences in the intestinal microbiota section. Results:No gallstone was found in the G-NS group and G-Probiotics group. The stone formation rates of the L-NS group and the L-Probiotics group were 100% and 60%, respectively, with statistical significance ( P<0.05). In the G-NS group, L-NS group, G-Probiotics group and L-Probiotics group the serum total cholesterol (TC) content were (2.03±0.34) mmol/L, (4.75±0.76) mmol/L, (1.64±0.49) mmol/L and (3.66±0.62) mmol/L, the serum low-density lipoprotein (LDL) cholesterol content was (0.57±0.10) mmol/L, (1.55±0.29) mmol/L, (0.73±0.37) mmol/L and (1.06±0.16) mmol/L, the serum leptin content was (6.77±0.76) μg/L, (19.24±3.97) μg/L, (3.21±1.32) μg/L and (11.67±1.05) μg/L. Comparison of serum TC and LDL: L-NS group was higher than G-NS group, L-NS group was higher than L-Probiotics group, L-Probiotics group was higher than G-Probiotics group, the difference was statistically significant ( P<0.01). Comparison of serum leptin showed that L-NS group was higher than G-NS group and L-Probiotics group, G-NS group and L-Probiotics group was higher than G-Probiotics group, the difference was statistically significant ( P<0.01). Compared with the control group, the intestinal flora diversity of mice in the simple high-fat diet group decreased, the relative abundance of harmful bacteria increased, and the relative abundance of beneficial bacteria decreased. After probiotics intervention, the intestinal flora diversity increased, the relative abundance of beneficial bacteria increased, and the relative abundance of harmful bacteria decreased. Conclusion:Probiotics can lower leptin levels and alleviate leptin resistance, decrease serum TC and LDL levels, and reduce cholesterol levels in bile, thus reducing cholesterol buildup in the gallbladder and preventing stone formation.

Objective To explore the correlations of lumbar bone mineral density(BMD)and metabolic syndrome(MS)in adult males.Methods Data of low dose chest CT and quantitative CT of 13 490 adult males were retrospectively analyzed,and lumbar BMD were measured to judge whether MS existed and the degree of MS,and the correlations of lumbar BMD with MS or not and the degree of MS,as well as of lumbar BMD value and the related indicators of MS were assessed.Taken lumbar BMD as the dependent variable,the age,low density lipoprotein cholesterol(LDL-C),blood uric acid(BUA),hemoglobin(Hb)and MS or not were included in multiple linear regression analysis to observe the impact of MS and related indicators on lumbar BMD.Results Among 13 490 adult males,3 900 were found with MS(MS group),while 9 590 were found without MS(non-MS group).Significant difference of lumbar BMD was detected between groups(P=0.001).Lumbar BMD values were negatively correlated with MS(rs=-0.025,P=0.004)and the degree of MS(rs=-0.038,P＜0.001),whereas positively correlated with abdominal obesity,high triglyceride and low HDL-C or not(rs=0.024,0.061,0.036,all P＜0.001)but negatively correlated with hypertension and hyperglycemia or not(rs=-0.135,-0.104,both P＜0.05).After adjustment of age,lumbar BMD of adult males was negatively correlated with MS or not as well as LDL-C(both P＜0.05),but positively correlated with BUA and Hb(both P＜0.001).Conclusion Lumbar BMD was associated with MS in adult males.
