Objective To explore the clinical characteristics of patients with alcoholic liver disease(ALD)of various traditional Chinese medicine(TCM)syndrome types.Methods A retrospective analysis was conducted in 129 patients with alcoholic liver disease who met the inclusion and exclusion criteria in Foshan Hospital of Traditional Chinese Medicine from 2018 to 2022.The general data of the patients as well as their TCM syndrome types and clinical information of liver and kidney function,blood lipid,liver transient elastography during the hospital visit were collected.The distribution of TCM syndrome types in ALD patients was analyzed,and the clinical characteristics of the ALD patients with various TCM syndrome types were explored.Results(1)Of the 129 patients,128(99.22%)were male and only one(0.78%)was female,the average age was(48.71±11.50)years old,and the average body mass index(BMI)was(23.82±3.98)kg·m-2.(2)Damp-heat accumulation syndrome was most common syndrome type in ALD patients,with a total of 70 cases(54.26%),and then came liver depression and spleen deficiency syndrome(24 cases,18.60%),internal obstruction of phlegm-damp syndrome(22 cases,17.05%),liver-kidney sufficiency syndrome(7 cases,5.43%),phlegm interweaved with blood stasis syndrome(3 cases,2.33%),and internal accumulation of blood stasis syndrome(3 cases,2.33%).(3)The analysis of clinical characteristics by non-parametric rank sum test showed that there were no statistically significant differences in BMI,alcohol consumption,aspartate aminotransferase(AST),gamma-glutamyltransferase(GGT),total bilirubin(TBIL),alkaline phosphatase(ALP),triglyceride(TG),liver stiffness measurement(LSM),and controlled attenuation parameter(CAP)which reflects the fat content of liver in ALD patients with various TCM syndrome types(P＜0.05 or P＜0.01).The prominent features were as follows:patients with the 4 types of liver depression and spleen deficiency,internal obstruction of phlegm-damp,phlegm interweaved with blood stasis,and internal accumulation of blood stasis had a BMI exceeding the standard(＞24 kg·m-2),whereas patients with damp-heat accumulation syndrome and liver-kidney deficiency syndrome,which accounted for 54.26%of the sample size,had a BMI within the normal range(23.03 kg·m-2 and 21.42 kg·m-2,respectively),and the BMI of these two types differed from that(26.44 kg·m-2)of the internal obstruction of phlegm-damp syndrome(P＜0.01),suggesting that more than half of the ALD patients had the normal BMI;moreover,the patients with internal obstruction of phlegm-damp also had the highest values of serum TG(2.69 mmol/L)and CAP(292 db/m)except for the highest BMI,indicating that patients with internal obstruction of phlegm-damp syndrome had a more serious degree of obesity and hepatic fat infiltration than those with other syndrome types;the levels of AST and GGT,which separately reflect the chronic inflammatory injury of liver and bile duct cell injury,were significantly increased in the patients with damp-heat accumulation syndrome and liver-kidney deficiency syndrome,and the LSM value of these two types of patients was also the highest in all of the syndrome types,the differences being all statistically significant(P＜0.05 or P＜0.01).Conclusion Damp-heat accumulation syndrome is the main TCM syndrome type of ALD patients,the degree of fatty infiltration of the liver and overweight of ALD patients are not corresponded to the severity of illness,and there are some differences in the clinical indicators of ALD patients with various TCM syndrome types.However,with cross reference to the data of the four diagnostic examinations of TCM and the clinical indicators,the accuracy of the TCM diagnosis of ALD is expected to be increased.

Purpose::Under-foot impact loadings can cause serious lower limb injuries in many activities, such as automobile collisions and underbody explosions to military vehicles. The present study aims to compare the biomechanical responses of the mainstream vehicle occupant dummies with the human body lower limb model and analyze their robustness and applicability for assessing lower limb injury risk in underfoot impact loading environments.Methods::The Hybrid III model, the test device for human occupant restraint (THOR) model, and a hybrid human body model with the human active lower limb model were adopted for under-foot impact analysis regarding different impact velocities and initial lower limb postures.Results::The results show that the 2 dummy models have larger peak tibial axial force and higher sensitivity to the impact velocities and initial postures than the human lower limb model. In particular, the Hybrid III dummy model presented extremely larger peak tibial axial forces than the human lower limb model. In the case of minimal difference in tibial axial force, Hybrid III's tibial axial force (7.5 KN) is still 312.5% that of human active lower limb's (2.4 KN). Even with closer peak tibial axial force values, the biomechanical response curve shapes of the THOR model show significant differences from the human lower limb model.Conclusion::Based on the present results, the Hybrid III dummy cannot be used to evaluate the lower limb injury risk in under-foot loading environments. In contrast, potential improvement in ankle biofidelity and related soft tissues of the THOR dummy can be implemented in the future for better applicability.

Objective:To explore the efficacy of negative pressure suction curettage combined with InMode diamond carving in the treatment of axillary osmidrosis.Methods:A total of 200 patients with bromhidrosis, 89 males and 111 females, aged (27.85±7.98) years, were prospectively included in the study from February 2022 to February 2023 in Huamei Zixin Medical Cosmetology Hospital in Sichuan Province. According to different treatment methods, the patients were divided into 2 groups with 100 cases in each group by random number table method. The control group received negative pressure suction curettage, and the experimental group received combination with InMode diamond carving. After follow-up for one year, the efficacy, recurrence rate and incidence of adverse reactions were compared between the two groups.Results:In the experimental group, 94 cases were cured, 6 cases were effective, 0 cases were ineffective; the effective rate was 100% (100/100). In the control group, 90 cases were cured, 5 cases were effective and 5 cases were ineffective; the effective rate was 95% (95/100). The effective rate of experimental group was higher than that of control group, and the difference was statistically significant (χ 2=5.128, P=0.024). In the experimental group, no cases relapsed, and the recurrence rate was 0. In the control group, 5 cases relapsed, and the recurrence rate was 5.3% (5/95). The recurrence rate of experimental group was lower than that of control group, and the difference was statistically significant (χ 2=5.390, P=0.020) In control group, 5 cases of subcutaneous hematoma, 1 case of scar contracture, 7 cases of scar hyperplasia, and 1 case of skin necrosis occurred; the incidence of adverse reactions was 14.0% (14/100). In the experimental group, 2 cases of subcutaneous hematoma, 5 cases of scar contracture and 5 cases of scar hyperplasia occurred; the incidence of adverse reactions was 12.0% (12/100). There was no significant difference in the incidence of postoperative adverse reactions between the two groups (χ 2 = 0.177, P=0.674). Conclusions:Negative pressure suction curettage combined with InMode diamond carving has better curative effect and lower recurrence rate in the treatment of axillary osmidrosis.

Objective To investigate the effect of preparation of shear-thinning CPC/LP nano-composite hydrogel for wound healing by supramolecular interaction of polydopamine(LP)and phy-cocyanin(CPC)based on nano-clayoxidation.Methods LP aggregates were formed by polymeriza-tion of dopamine monomers in weak alkaline oxygen-containing environment of nano-clay dispersion,and then mixed it with multifunctional CPC to form shear-thinning nanocomposite hydrogels by electro-static action and Schiff base.The microstructure,rheological properties,blood compatibility and wound healing effect of hydrogel were studied systematically.Results The gelation performance of CPC/LP nanocomposite hydrogel was related to LP content.When LP content was 3％and CPC con-tent was 0.5％,stable gel could be formed;rheological test results showed that the nanocomposite hydrogel had the properties of shear thinning and self-healing;the results of blood compatibility test showed that the hemolysis rate of the nanocomposite hydrogel was less than 5％,and it had good blood compatibility.In addition,the nanocomposite hydrogel could be injected into the injury site through a smaller needle to promote wound healing.Conclusion CPC/LP nanocomposite hydrogel exhibits excellent injectable properties and can effectively promote wound healing.

Objective: To evaluate the clinical value of new coagulation biomarkers including soluble thrombomodulin (sTM) and tissue plasminogen activator inhibitor complex (t-PAI·C) for the diagnosis and prognosis of sepsis in children. Methods: The prospective observational study enrolled 59 children who were diagnosed with sepsis including severe sepsis and septic shock in the Department of Pediatric Critical Care Medicine of Shanghai Children's Medical Center affiliated to the Medical College of Shanghai Jiao Tong University from June 2019 to June 2021. The sTM, t-PAI·C and conventional coagulation tests were detected on illness day one of sepsis. Twenty healthy children were selected as the control group, and the above parameters were detected on the day of inclusion. Children with sepsis were divided into survival group and non-survival group according to prognosis at discharge. Baseline comparisons between groups were performed using Mann-Whitney U test. Multivariate Logistic regression analysis was used to evaluate the risk factors for the diagnosis and prognosis of sepsis in children. Receiver operating characteristic (ROC) curve was conducted to evaluate the predictive values of above variables for the diagnosis and prognosis of sepsis in children. Results: The sepsis group included 59 patients (39 boys and 20 girls), aged 61(22, 136)months. There were 44 patients in the survival group and 15 patients in the non-survival group, respectively. The control group consisted of 20 boys, aged 107 (94,122) months. Patients in the sepsis group had higher sTM and t-PAI·C ((12 (9, 17)×10³ vs. 9(8, 10)×10³ TU/L, 10(6, 22) vs. 2 (1, 3) μg/L, Z=-2.15, -6.05, both P<0.05) compared with children in the control group. The t-PAI·C was superior to sTM for the diagnosis of sepsis. The areas under the curve (AUC) of t-PAI·C and sTM for the diagnosis of sepsis were 0.95 and 0.66, respectively, and the optimal cut-off value were 3 μg/L and 12×10³ TU/L, respectively. Patients in the survival group had lower sTM (10 (8, 14)×10³ vs. 17 (11, 36)×10³ TU/L, Z=-2.73, P=0.006) than those in the non-survival group. Logistic regression analysis showed that sTM was a risk factor for death at discharge (OR=1.14, 95%CI 1.04-1.27, P=0.006). The AUC of sTM and t-PAI·C for predicting death at discharge were 0.74 and 0.62, respectively, and the optimal cut-off values were 13×10³ TU/L and 6 μg/L, respectively. The AUC of sTM combined with platelet counts for predicting death at discharge was 0.89, which was superior to sTM and t-PAI·C. Conclusion: The sTM and t-PAI·C had clinical application values in diagnosing and predicting prognosis in pediatric sepsis.
