Objective To establish a off-pump leukocyte depletion method in canines.Methods Twenty-one healthy adult mongrel dogs of both sexes, weighing 10-12 kg, were randomized into 2 groups: control group (group C, n = 9) and leukocyte depletion group (group LD, n = 12) . An extracorporeal leukocyte filtration end was constructed by aseptic puncture of the bilateral external jugular veins via a blood transfusion line and the leukocyte filter for extracorporeal leukocyte depletion. In group LD, blood was filtered with a MP-300 blood line and a SQ40S leucocyte depletion filter one end placed in the right external jugular vein (artery end) and the other end placed in the left external jugular vein (venous end). After heparin anticoagulation, a MP-300 blood line pump was used as the power. Blood was filtered at a rate of 75 ml/min and it was maintained for 60 min. The artery end was then closed, normal saline injected into the closed circuit, the remaining blood pumped into the body, and then the venous end closed. In group C, aseptic puncture of the bilateral external jugular veins was performed. Arterial blood samples were taken immediately before leukodepletion (baseline, T_0 ) , at 10, 20, 30, 40, 50 and 60 min of leukodepletion (T_(1-6) , depletion period), and at 10, 20, 30, 40, 50, 60, 120, 180 and 270 min after leukodepletion (T_(7-15) , recovery period) for determination of blood routine. MAP, HR, RBC.Plt and body temperature were recorded at T_0 , T_6 , T_(12) and T_(15) . Results There were no significant difference in MAP and RBC between the two groups ( P > 0.05 ) . HR, body temperature, and Plt were significantly lower in group LD than in group C (P < 0.05) .The leukocyte concentration was lower during depletion period in group LD than in group C ( P < 0.05) , while there was no significant difference in leukocyte concentration during recovery period between the two groups (P > 0.05 ). Conclusion The off-pump leukocyte depletion method is successfully established and has exact efficacy with less adverse effects in this study.

Objective: To explore the dynamic association and gender difference among body dissatisfaction, weight bias internalization and eating disorders in junior high school students, so as to provide the reference for the rational implementation of relevant intervention activitites. Methods: From June to December 2023, a cluster sampling method was used to select 698 students from a middle school in Fuzhou for three followup surveys for a period of 6 months (T1:June 2023, T2:September 2023, T3:December 2023). The Eating Disorders Inventory-Body Dissatisfaction (EDI-BD), the Chinese Version of the Weight Bias Internalization Scale for Mainland Chinese Children and Adolescents (C-WBIS), and the Chinese Version of the Eating Disorder Examination Questionnaire (C-EDE-QS) were used for investigation. Analysis of variance, t test, Pearson correlation analysis and crosslagged analysis were used for statistical analysis. Results: T1 there were statistically significant differences in body dissatisfaction scores among junior high school students of different grades and with or without leftbehind experience (t=-3.25, 2.12, P<0.05). There were statistically significant differences in weight bias internalization (t=-3.03, -2.43, 2.43) and eating disorders (t=-4.64, -2.04, 2.63) among junior high school students of different genders, grades and with or without leftbehind experience (P<0.05). Crosslagged analysis showed that body dissatisfaction was a predictor of weight bias internalization (βT1-T2=0.22, βT2-T3=0.12) and eating disorders (βT1-T2=0.09, βT2-T3=0.17, P<0.01). Eating disorders could predict body dissatisfaction (βT1-T2=0.15, βT2-T3=0.13) and weight bias internalization (βT1-T2=0.14, βT2-T3=0.23, P<0.01). The mutual predictive effect of body dissatisfaction, weight bias internalization and eating disorders varied with gender. T2 weight bias internalization in girls had a predictive effect on T3 body dissatisfaction (β=0.11). T1 and T2 eating disorders in girls had a predictive effect on T2 and T3 weight bias internalization (βT1-T2=0.26, βT2-T3=0.21) (P<0.01). Conclusions Body dissatisfaction, weight bias internalization, and eating disorders of the junior high school students are interconnected. And there is a certain twoway correlation and gender difference between body dissatisfaction, weight bias internalization and eating disorders in junior high school students.

Objective: To evaluate the effect of Tai Chi and Qigong on patients with lumbar disc herniation (LDH). Methods: Relevant data were retrieved from nine English and Chinese databases, including Cochrane Library, PubMed, and Wanfang Data, etc. from inception to June 2024. All published randomized controlled trials assessing the effect of Tai Chi and Qigong on visual analog scale (VAS), Japanese Orthopedic Association (JOA) score, and other health indicators in participants with LDH compared to usual medical care or other treatments were included. Grey literature, trials involving the pushing of hands (Tui Shou) or Tai Chi with weapons, and trials with co-interventions (Tai Chi/Qigong plus another treatment) were excluded. Methodological quality was analyzed using the Cochrane risk of bias tool, and evidence quality was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) tool. Results: Fourteen trials (954 patients) were included in this study. Tai Chi and Qigong were associated with lower VAS pain scores (standardized mean difference −0.55, 95% confidence interval [CI] −0.95 to −0.15, P = .01), higher JOA scores (mean difference [MD] 4.40, 95% CI 2.62 to 6.18, P < .001) and straight leg raise test results (MD 9.40°, 95% CI 7.64 to 11.15, P < .001) in patients with LDH. Furthermore, compared with usual care, Tai Chi and Qigong showed enhanced effects on pain and JOA scores. When compared to other exercises or massage, the effect on pain scores was similar but that on JOA scores was significant. Conclusions Tai Chi and Qigong may have favorable effects on VAS pain and JOA scores compared with usual care, and on JOA scores compared with other exercises or massage in patients with LDH. Given the overall poor quality of the evidence, the results of current study should be interpreted cautiously.

OBJECTIVETo compare the antitussive activity of three kinds of Stemonae Radix specified in the Chinese Pharmacopoeia, including roots of Stemona sessilifolia, S. japonica and S. tuberosa.

METHODThe antitussive activity was determined in mouse after cough induction by ammonia aerosol stimulation and the number of cough in 2 min were detected with codeine as positive control.

RESULTAll the decoctions, the total alkaloid fractions and non-alkaloid fractions of S. sessilifolia, S. japonica and three chemical types of S. tuberosa showed significant antitussive effect and exhibited a dose-dependent inhibition of coughing. The ED50 values showed that the antitussive activity strength for both total alkaloid fractions and the decoctions are: S. tuberosa (Type I) > S. sessilifolia > S. japonica. The total alkaloid fractions had more potent atitussive activity than the decoctions and non-alkaloid fractions. The antitussive activity strength for the three chemical types of S. tuberosa is: Type I > Type III > Type II. The samples from different producing areas for the same species of Stemonae Radix had no significant differences in antitussive activity. The result also showed that the honey-processed slice had much stronger antitussive activity than raw slice.

CONCLUSIONThe antitussive efficacies of Stemonae Radix were influenced by chemical diversity both in same species and among different species, different fractions and processed method.

Norepinephrine (NE) can raise blood pressure and speed up heart rate. However, because its effect of raising heart rate is less than that of reflex reduction of heart rate caused by the increase of blood pressure, NE causes more heart rate decrease in patients. A case of tachyarrhythmia caused by low dose NE was admitted to department of intensive care unit (ICU) of Shijiazhuang Third Hospital. The heart rate of the patient increased with the elevation of NE application dose. A variety of antiarrhythmic drugs was invalid. The related examination was prescribed to eliminate the cause of arrhythmia caused by the disorder of electrolysis and thyroid function, and found that heart rate decreased as the dose of NE tapered. After NE was stopped, the patient recovered sinus rhythm. During one month of follow-up, the patient's heart rhythm was normal. Therefore, the occurrence of tachyarrhythmia is related to NE.

OBJECTIVE: To explore the influence of hypoxemia on the hearing of children with childhood obstructive sleep apnea-hypopnea syndrome (OSAHS). METHOD: Auditory brainstem response (ABR) and distortion-product otoacoustic emission (DPOAE) was recorded in 68 ears and 60 ears respectively of children suffering from OSAHS with "A" tympanogram. Meanwhile, ABR and DPOAE was also recorded in 30 controls of children with "A" tympanogram. RESULT: There was no statistical difference between the mild OSAHS group and the control group in the latency of wave I, III and V, the interval between wave I and III, III and V, I and V. There was significant difference between the moderate and severe OSAHS group and the control group in the delayed latency of wave I. There was significant difference between the mild OSAHS group and the control group in the amplitudes of DPOAE at 8 kHz. There was significant difference between the moderate and severe OSAHS group and the control group in the amplitudes of DPOAE at 6 kHz and 8 kHz. CONCLUSION Cochlear function was affected when AHI > or = 10/h. ABR and DPOAE could be used to detect the early damagement of auditory function in childhood OSAHS.
