With the rapid development of social economy and the continuous improvement of human living standard, the incidence, fatality and recurrence rates of cardiovascular disease (CVD) are increasing year by year, which seriously affects people's life and health. Conventional therapeutic drugs have limited improvement on the disability rate, so the search for new therapeutic drugs and action targets has become one of the hotspots of current research. In recent years, the therapeutic role of the natural compound rosmarinic acid (RA) in CVD has attracted much attention, which is capable of preventing CVD by modulating multiple signalling pathways and exerting physiological activities such as antioxidant, anti-apoptotic, anti-inflammatory, anti-platelet aggregation, as well as anti-coagulation and endothelial function protection. In this paper, the role of RA in the prevention of CVD is systematically sorted out, and its mechanism of action is summarised and analysed, with a view to providing a scientific basis and important support for the in-depth exploration of the prevention value of RA in CVD and its further development as a prevention drug.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

BackgroundSleep disorder can adversely affect human physical and mental health， with important implications for socioeconomic development. And higher vocational college students are subject to various pressures and stimuli exerted by academic studies， job seeking and family socioeconomic status， which may contribute to the onset insomnia symptom or sleep disorder. ObjectiveTo discuss the sleep status and influencing factors among higher vocational college students， and to provide references for improving their sleep status. MethodsIn January and February， 2022， a stratified random sampling method was utilized to enroll 3 300 students from five higher vocational colleges in Wenjiang district of Chengdu city. All the participants were assessed using Insomnia Severity Index （ISI）， Patient Health Questionnaire Depression Scale-9 item （PHQ-9） and Generalized Anxiety Disorder Scale-7 （GAD-7）. Pearson correlation analysis was conducted to test the correlation of ISI with PHQ-9 and GAD-7 scores， and the Logistic regression analysis was performed to identify the influencing factors of insomnia symptom in higher vocational college students. ResultInsomnia symptom was detected in 81.90% （2 497 / 3 300） of higher vocational college students. The detection rate of insomnia symptom among vocational college students yielded statistical difference in terms of gender， family socioeconomic status， being an only child or having siblings， degree of psychological pressure exerted by academic studies or job seeking， amount of hours spent on Internet per day， frequency of physical exercise， and the presence or absence of anxiety symptom and depression symptom （χ²=21.032， 22.172， 8.983， 75.939， 36.781， 32.350， 54.512， 86.561， P<0.01 or 0.05）. Among higher vocational college students， ISI score was positively correlated with GAD-7 and PHQ-9 scores （r=0.620， 0.714， P<0.01）， and GAD-7 score was positively correlated with PHQ-9 score （r=0.824， P<0.01）. Gender， family socioeconomic status， degree of psychological pressure exerted by academic studies or job seeking， amount of hours spent on Internet per day， frequency of physical exercise， and the presence or absence of anxiety symptom and depression symptom were effective factors in predicting the insomnia symptom in higher vocational college students （P<0.01 or 0.05）. ConclusionFemale gender， average and below average family socioeconomic status， moderate-to-severe degree of psychological pressure exerted by academic studies or job seeking， spending 2~5 h， 5~7 h or >7 h on Internet per day， inadequate physical exercise and presence of depressive symptom are the risk factors for insomnia symptom in higher vocational college students.［Funded by Sichuan Provincial Primary Health Development Research Center in 2022， North Sichuan Medical College （number， SWFZ22-C-89）］

Compound 1 is a novel macrocyclic flavonoid, and all the others are reported from this plant for the first time. In vitro cytotoxic activities of compounds 1-7 were evaluated by MTS testing with five cancer cell lines. Compound 7 exhibited weak cytotoxicity against tumor cell lines A549, SMMC-7721, and SW480.

OBJECTIVE: To analyze the clinical features of acute myeloid leukemia (AML)/high-risk myelodysplastic syndrome (MDS) patients aged over 60 years old. METHODS: The clinical data of 61 elderly newly diagnosed patients with AML and high-risk MDS who submitted to the Department of Hematology/Oncology of the First Affiliated Hospital of Tsinghua University from January 2009 to April 16, 2021 were retrospectively analyzed. These patients were divided into chemotherapy group (45 cases) and supportive treatment group (16 cases). The overall survival (OS) was analyzed by Kaplan-Meier method, and the prognostic factors of survival were analyzed by multivariate Cox regression. RESULTS: After 2 cycles of induction chemotherapy, the complete remission (CR) rate was 37.8% (17/45), and overall response rate was 62.2% (28/45) in the chemotherapy group. The median OS in the chemotherapy group and supportive treatment group was 11.3 (0.07-43) and 1.6 (0.33-7.72) months, respectively (P<0.001). The median OS in patients who reached CR or did not reach after 1 cycle of induction chemotherapy was 19.8 (10-30.63) and 8.17 (0.07-43) months, respectively (P<0.05), while after 2 cycles was 22.7 (4.2-43) and 7.26 (0.07-26) months, respectively (P<0.001). Univariate analysis showed that age > 80 years old, CCI score > 2, PS score > 2 and supportive treatment were the adverse prognostic factors for OS. Further multivariate analysis suggested that chemotherapy was the only independent prognostic factor for OS (HR=0.140, 95%CI: 0.048-0.409, P<0.001). In the chemotherapy group, univariate analysis showed that CCI score > 2 and failure to reach CR after induction chemotherapy were poor prognostic factors. Multivariate analysis showed that CCI score > 2 (HR=0.139, 95%CI: 0.050-0.384, P<0.001) and failure to achieve CR after induction chemotherapy (HR=0.103, 95%CI: 0.041-0.259, P<0.001) were the adverse prognostic factors for OS. The patients were tolerant to side-effect of chemotherapy. CONCLUSION Appropriate chemotherapy can prolong the survival of elderly patients with AML and high-risk MDS.

OBJECTIVE: To investigate the age distribution of Mongolian patients with cerebral infarction caused by thrombosis and the correlation and consistency between thromboelastography (TEG) and four parameters of coagulation. METHODS: The age distribution of 298 Mongolian patients with cerebral infarction treated in Affiliated Hospital of Inner Mongolia Minzu University from January 2020 to December 2021 and their TEG, four items of routin coagulation and platelet count were analyzed retrospectively. The correlation and consistency of above-mentioned two detection methods were statistically analyzed. RESULTS: The onset age of 298 Mongolian patients with cerebral infarction was mainly 61-70 years old, accounting for 38.3%, followed by 51-60 years old, accounting for 26.8%. The R time detected by TEG was linearly correlated with PT and APTT（r=0.186，r=0.152）. K value, MA value and α-Angle measured by TEG was linearly correlated with Fib (r=-0.364，r=0.616，r=0.359), K value, MA value and α-Angle measured by TEG was linearly correlated with Plt (r=0.318，r=0.519，r=0.301). The R time detected by TEG was consistent with PT and APTT, and the Kappa values were 0.252 (P<0.001), 0.336 (P<0.001). K, MA, and α-Angle measured by TEG was consistent with Fib, the Kappa values were 0.265 (P<0.001), 0.289 (P<0.001) and 0.290 (P<0.001), respectively; K、MA and α-Angle measured by TEG was consistent with Plt, the Kappa values were 0.276 (P<0.001), 0.285 (P<0.001) and 0.302 (P<0.001), respectively. CONCLUSION The onset age of Mongolian patients with cerebral infarction caused by thrombosis is mainly 61-70 years old, followed by 51-60 years old. The onset age shows a younger trend. There is a significant correlation between TEG and coagulation, but the consistency is weak, therefore, the two methods can not be replaced each other.

OBJECTIVE: To compare the therapeutic effect of Tongdu Tiaoqi acupuncture (acupuncture for unblocking governor vessel and regulating qi ) combined with warming acupuncture, Tongdu Tiaoqi acupuncture, abdominal moxibustion and oral tamsulosin hydrochloride sustained release capsule on postoperative urinary retention. METHODS: A total of 120 patients with postoperative urinary retention were randomized into an acupuncture-moxibustion group, an acupuncture group, a moxibustion group and a medication group, 30 cases in each group. Tongdu Tiaoqi acupuncture combined with warming acupuncture were applied in the acupuncture-moxibustion group. Tongdu Tiaoqi acupuncture was applied at Baihui (GV 20), Shuigou (CV 26) etc. in the acupuncture group. Moxibustion was applied at Qihai (CV 6), Guanyuan (CV 4), Shuidao (ST 28) and Sanyinjiao (SP 6) in the moxibustion group. Tamsulosin hydrochloride sustained release capsule was given orally in the medication group. The treatment was once a day, and 5-day treatment was required in each group. Before and after treatment, the residual urine volume of bladder, the visual analogue scale (VAS) score and the time of first urethral catheter removal were observed, and the clinical efficacy was compared in the 4 groups. RESULTS: After treatment, the residual urine volume of bladder was decreased compared before treatment in the 4 groups (P<0.05), and that in the acupuncture-moxibustion group was less than the other 3 groups (P<0.05). After treatment, the VAS scores were decreased compared before treatment in the acupuncture-moxibustion group, the acupuncture group and the moxibustion group (P<0.05), and those in the 3 groups were lower than the medication group (P<0.05). The time of first urethral catheter removal in the acupuncture-moxibustion group was earlier than the other 3 groups (P<0.05). The total effective rate was 93.3% (28/30) in the acupuncture-moxibustion group, which was superior to 63.3% (19/30) in the acupuncture group, 60.0% (18/30) in the moxibustion group and 66.7% (20/30) in the medication group (P<0.05). CONCLUSION The therapeutic effect of Tongdu Tiaoqi acupuncture combined with warming acupuncture on postoperative urinary retention is superior to simple acupuncture, abdominal moxibustion and tamsulosin hydrochloride sustained release capsule.

Objective:To investigate the effect of Qixian Tongluo prescription on neural function recovery in patients with cerebral infarction and its mechanism. Method:A total of 100 inpatients （January to June，2020）with cerebral infarction in the Neurology Department of Wenzhou Hospital of Traditional Chinese Medicine were assigned to an experimental group （n=50） and a control group （n=50） according to the random number table. Both groups received conventional treatment of western medicine，while the experimental group took additional Qixian Tongluo prescription. Treatment lasted for 12 weeks. The clinical efficacy，National Institutes of Health Stroke Scale （NIHSS） score， the modified Barthel index （MBI），Fugl-Meyer assessment （FMA） score， and levels of brain-derived neurotrophic factor（BDNF），vascular endothelial growth factor（VEGF）， and stromal cell-derived factor-1（SDF-1） in peripheral blood of the two groups before and after treatment were compared. Result:The total response rate in the experimental group was 84.00%（42/50），higher than 66.00%（33/50） in the control group （Z=-7.365，P<0.05）. There was no significant difference in the scores of MBI，FMA， and NIHSS before treatment between the two groups. The MBI and FMA scores of the two groups increased （P<0.01）， and the NIHSS scores decreased （P<0.05， P<0.01）. Compared with the control group after treatment， the experimental group showed increased MBI and FMA scores and decreased NIHSS score （P<0.05）. There was no significant difference in BDNF level between the two groups before and after treatment. The VEGF and SDF-1 levels in the peripheral blood of the two groups were higher than those before treatment （P<0.05）， and the experimental group was higher than the control group （P<0.05）. Conclusion:Qixian Tongluo prescription can effectively improve the clinical efficacy，the quality of life， and the prognosis of patients with cerebral infarction during convalescence. The underlying mechanism is associated with the promotion of the expression of endogenous VEGF and SDF-1 in the peripheral blood to activate the SDF-1/chemokine receptor 4（CXCR4） signaling pathway， induce the recruitment and mobilization of endothelial progenitor cells， and facilitate the angiogenesis and repair of ischemic brain tissues.

Caveolin-1 (CAV-1) is related to inflammation, oxidative damage, and immunity. In order to obtain a series of dibenzoylmethane halophenols with strong anti-inflammatory and antioxidant effects targeting CAV-1, twenty-nine target compounds were therefore synthesized by Baker-Ventaraman rearrangement and demethylation reaction, starting from the substituted benzoyl chloride and o-hydroxyacetophenone, and their interactions with CAV-1 were investigated by BLI technique. Their in vitro anti-inflammatory and antioxidant properties were also evaluated. The results showed that compounds A6, A17, A18, and A29 not only specifically bind to CAV-1, but also present strong anti-inflammatory and antioxidant effects. These results suggest that this class of compounds can affect the signaling pathways related to inflammation and oxidative stress by directly acting on CAV-1. In particular, these compounds exhibit the most significantly inhibitory effects on IL-1β and COX-2 release. IL-1β plays a key regulatory role in the development of arthritis. Therefore, it is worth expecting for the application of such compounds in the prevention and treatment of arthritis.
