Chinese Journal of Trauma 2010;26(11):999-1002
Objective To investigate the changes of thrombomodulin (TM) and von Willebrand factor (vWf) and their clinical significance in patients with severe brain injury. Methods The study involved 62 patients with severe brain injury who were divided into diffuse axonal injury group (28 patients) and focal brain injury group (34 patients). Then, the 62 patients were divided into young group (16-30 years old, 20 patients), middle-aged group (31-65 years old, 20 patients) and elderly group ( >65 years old, 22 patients). The serum levels of TM and vWf were determined at days 1 and 7 after injury respectively. ELISA method was employed to determine the serum levels of TM and vWf.Results The vWf in focal brain injury group was significantly higher than that of diffuse axonal injury group at days 1-7 after injury ( P < 0.05 ). Compared with the young and middle-aged groups, the TM and vWf levels in the elderly group at day 1 after injury were significantly elevated ( P < 0. 05 ). The TM levels in patients with delayed traumatic intracerebral hematoma (DTICH) were significantly higher than that in patients without DTICH (P < 0. 05). Conclusions In the acute stage of severe brain injury,injury severity and activation of endothelial cells varies in patients with different types of injury and at different ages. TM is one of sensitive indicators to reflect the cerebal vascular endothelial cell injury. It is very meaningful to assess the prognosis of severe brain injury by measuring serum levels of TM and vWf and take TM as a predictive indicator for DTICH.

The Journal of Practical Medicine 2018;34(8):1368-1371,1375
Objective The study was to determine the relationship between acquired admission and/or pre-operative Rotterdam CT scores and TBI prognosis after standard decompressive craniectomy. Methods We chose 1 108 cases simple TBI patients with unilateral decompressive craniectomy(DC) from January 2011 to May 2016 in our hospital as the research object,and 212 patients which were reached standard were included in our retro-spective study. According to general data analysis,GOS 3 month after injury,the subject were divided into poor prognosis group and good prognosis group.Multiple factors logistic regression analysis was used to determine the re-lationship between acquired admission or preoperative Rotterdam CT scores and mortality or GOS in 3 month after injury. Results A total of 85 patients(40.1%) had a good prognosis and 127(59.9%) had a poor prognosis.A comparative analysis of different admission and preoperative Rotterdam CT scores groups showed the mortality and poor prognosis rates were statistically significant(P=0.00) in 4-6 groups of patients after injury 3 months.Multi-ple factors logistic regression analysis showed admission and preoperative Rotterdam CT scores were significantly as-sociated with mortality and poor prognosis(P<0.05).Conclusions Rotterdam CT scores provide important prog-nostic information of TBI patients with DC. Combined admission Rotterdam CT scores and preoperative Rotterdam CT scores may forecast the early mortality and long-term outcome for TBI patients.

Background Natural product sanguinarine chloride (SC) can significantly alleviate liver fibrosis and acute liver injury in mice, but whether it has a protective effect on mouse liver injury caused by sodium arsenite (SA) has not been studied. Objective To verify if SC may present preventive and therapeutic effects on SA-induced liver injury in mice. Methods A total of 140 SPF male Kunming mice were randomly divided into two sub-studies, which included a prevention sub-study and a treatment sub-study. In each sub-study, a blank group (normal saline), a model group (5 mg·kg−1 SA), and a positive control group (11.375 mg·kg−1 bicyclol and 182 mg·kg−1 glutathione), as well as SC low, medium, and high dose groups (25, 50, and 100 mg·kg−1) were arranged with 10 mice in each group. In the prevention sub-study, the blank group was given normal saline, the model group was given SA, and the other groups (the SC low, medium, and high dose groups and the positive control group) were given the corresponding treatment 30 min before gavage of SA, once a day, for 28 d. In the treatment sub-study, except for the blank group which was given normal saline, the other groups were given SA for 28 d, then the model group was given normal saline, and the other groups were given the corresponding treatment every day for 28 d. After the experiment, the mice were sacrificed to evaluate selected physiological and biochemical indicators in serum and liver tissue and to observe histopathological changes after HE staining. Results In either sub-study of preventive effect or treatment effect: compared with the blank group, body weight, liver weight, liver coefficient, as well as serum alanine transaminase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), malondialdehyde (MDA), glutathione peroxidase (GSH), and superoxide dismutase (SOD) among all SC groups were not significantly different (P>0.05); but compared with the model group, the SC groups showed increased body weight (P<0.01), decreased liver weight and liver coefficient (P<0.01), reduced ALT, AST, TBIL, and MDA (P<0.05 or P<0.01), and increased GSH and SOD with (P<0.05 or P<0.01) or without significance; compared with the positive control group, no differences were found in the above indicators (P>0.05). The result of histopathological evaluation showed that the SC groups had a clear liver lobule structure, neatly arranged hepatic cords, and less infiltration of inflammatory cells. Conclusion SC has both preventive and therapeutic effects on SA-induced liver injury in mice.

Objective:To explore the chain mediating effect of emotion dysregulation and trait anger between childhood trauma and aggressive behavior in adolescents.Methods:A sample of 1 333 undergraduates were recruited to complete the questionnaires about childhood trauma, aggressive behavior, emotion dysregulation, trait anger.The SPSS 23. 0 and Mplus 8.3 software were used to analysis data and test intermediate effect.Results:The scores of childhood trauma, aggressive behavior, difficulties in emotion regulation and trait anger were (33.624±8.211), (53.995±12.307), (91.781±17.518), (23.352±5.477), respectively. Correlation analysis showed that childhood trauma, aggressive behavior, emotion dysregulation and trait anger were positively correlated with each other( r=0.209-0.614; all P<0.01). Mediation modeling analysis showed that childhood trauma had a significant direct effect on aggressive behavior. The direct effect value was 0.121, accounting for 35.8% of the total effect. The total indirect effect of childhood trauma on aggressive behavior was 0.217, accounting for 64.2% of the total effect. The mediating effect of emotion dysregulation as mediator between childhood trauma and aggressive behavior was 0.035, accounting for 10.4% of the total effect. The mediating effect of trait anger as mediator between childhood trauma and aggressive behavior was 0.108, accounting for 31.9% of the total effect. The chain mediating effect of emotion dysregulation and trait anger was 0.074, accounting for 21.9% of the total effect. Conclusion:Emotion dysregulation and trait anger exert a multiple mediating effect on the relationship between childhood trauma and aggressive behavior.

Purpose:
Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease, and Th17 cells are key factors in the pathogenesis of human inflammatory conditions, such as RA. Catalpol (CAT), a component in Rehmanniae Radix (RR), has been found to regulate human immunity. However, the effects of CAT on Th17 cell differentiation and improvement of RA are not clear.
Materials and Methods:
Collagen-induced arthritis (CIA) mice were constructed to detect the effects of CAT on arthritis and Th17 cells. The effect of CAT on Th17 differentiation was evaluated with let-7g-5p transfection experiments. Flow cytometry was used to detect the proportion of Th17 cells after CAT treatment. Levels of interleukin-17 and RORγt were assessed by qRT-PCR and enzyme-linked immunosorbent assay. The expression of signal transducer and activator of transcription 3 (STAT3) was determined by qRT-PCR and Western blot.
Results:
We found that the proportion of Th17 cells was negatively associated with let-7g-5p expression in CIA mice. In in vitro experiments, CAT suppressed traditional differentiation of Th17 cells. Simultaneously, CAT significantly decreased Tregs-to-Th17 cells transdifferentiation. Our results demonstrated that CAT inhibited Tregs-to-Th17 cells transdifferentiation by up-regulating let-7g-5p and that the suppressive effect of CAT on traditional differentiation of Th17 cells is not related with let-7-5p.
Conclusion
Our data indicate that CAT may be a potential modulator of Tregs-to-Th17 cells transdifferentiation by up-regulating let-7g-5p to reduce the expression of STAT3. These results provide new directions for research into RA treatment.

Objective:To investigate the association between body mass index (BMI) trajectories in children and adolescents and subclinical renal damage (SRD) in adulthood.Methods:4 623 participants aged 6-18 years old were recruited from the ongoing cohort of Hanzhong adolescent hypertension study in 1987, and the subjects were followed up in 1989, 1992, 1995, 2005, 2013 and 2017, respectively. Group-based trajectory modeling was used to identify distinct BMI trajectories in longitudinal analysis. Generalized linear model was applied to examine the association between different BMI trajectories and SRD incidence in adulthood.Results:A total of 2 678 subjects from childhood to adulthood were enrolled in this study. All subjects were divided into three groups according to three distinct BMI trajectories: low-increasing BMI group ( n=1 017), moderate-increasing BMI group ( n=1 353), and high-increasing BMI group ( n=308). Over follow up for 30 years, a total of 248 participants (9.3%) developed SRD. Urinary albumin-to-creatinine ratio (uACR) in low to high-increasing BMI group was 0.9(0.6, 1.4), 1.0(0.7, 1.7), 1.6(0.8, 3.2), respectively ( P trend<0.001), and estimated glomerular filtration rate was 98.5(87.6, 111.6) , 96.2(86.4, 109.7), 95.3 (87.5, 125.0) ml·min -1·(1.73 m 2) -1, respectively ( P trend=0.025). The generalized linear model analysis showed that uACR was increased linearly from low to high-increasing BMI group [ β=3.16(95% CI 1.02-5.31), Ptrend=0.004]. There was no correlation or linear trend between BMI trajectory and estimated glomerular filtration rate [ β=-2.30(95% CI-5.18-0.57), Ptrend=0.117]. Compared with the low-increasing BMI group, the high-increasing BMI group had greater odds of experiencing SRD in adulthood after adjusting for multiple confounders such as age, gender, medical history and lifestyle ( OR=2.83, 95% CI 1.84-4.36, Ptrend<0.001). Conclusions:Higher BMI trajectorie is correlated with higher level of uACR and risk of SRD in middle age. Identifying long-term BMI trajectorie from early age may assist in predicting individuals′ renal function in later life.

ObjectiveTo compare the clinical effect of heat-sensitive moxibustion before menstruation and since the first day of menstruation on primary dysmenorrhoea (PD), thereby optimizing the clinical treatment plan. MethodsSixty patients with PD were randomly divided into pretreatment group (treated before menstruation) and conventional treatment group (treated since the first day of menstruation) of 30 cases each. For all patients, the area surrounded by bilateral Zigong (EX-CA1) and bilateral Guilai (ST 29) in the supine position, and that formed by bilateral Shenshu (BL 23) and Ciliao (BL 32) in the prone position were selected for circling moxibustion (2 min), sparrow-pecking moxibustion (1 min), and then moxibustion along the channels to stimulate the moxibustion sensation and obtain two heat-sensitive points with the best sensation for treatment. In the pretreatment group, moxibustion was applied 3-7 days before the onset of menstruation, and in the conventional treatment group, moxibustion was applied on the day of menstruation. Both groups were treated once daily for 7 days per menstrual cycle for 3 consecutive cycles. The clinical outcomes of the two groups were measured before and after treatment in terms of the COX menstrual pain symptom scale (CMSS) scores, visual analogue scale for pain (VAS) scores, and uterine artery hemodynamic indicators including blood pulsation index (PI) and resistance index (RI), and the clinical effect was compared. ResultsAfter treatment, the CMSS scores, VAS scores, PI and RI in the two groups decreased, and lower scores were found in the pretreatment group (P<0.05 or P<0.01). The total effective rate after treatment was 93.3% (28/30) in the pretreatment group, which was better than 73.3% (22/30) in the conventional treatment group (P<0.05). ConclusionThe clinical effect of heat-sensitive moxibustion before the menstruation for PD was better than that implemented since the first day of menstruation, by significantly improving the patients' dysmenorrhoea symptoms and uterine artery blood flow index.
