The antidepressant activity and molecular mechanisms of Yueju Wan volatile oil were investigated. The Yueju Wan volatile oil was extracted by using supercritical CO_2. Gas chromatography-mass spectrometry(GC-MS) combined with network pharmacology identified 28 chemical constituents in Yueju Wan volatile oil, primarily terpenes and lactones. A total of 123 overlapping targets were associated with depression, including core targets of interleukin-1β(IL-1β), signal transducer and activator of transcription 3(STAT3), and caspase-3(CASP3). These targets were mainly involved in the prolactin, advanced glycation end products/receptor(AGE/RAGE), and phosphoinositide 3-kinase/protein kinase B(PI3K/Akt) signaling pathways. A reserpine-induced depression mouse model was established to evaluate the therapeutic effects and mechanisms of Yueju Wan volatile oil. The effects of Yueju Wan volatile oil on depression-like behavior in mice were evaluated by analyzing body mass, body temperature index, tail suspension immobility time, forced swimming immobility time, and sucrose preference. Hematoxylin-eosin(HE) staining revealed neuronal protection of Yueju Wan volatile oil in the brain of mice. Enzyme-linked immunosorbent assay(ELISA) and Western blot were employed to detect the protein expression of AGEs, IL-1β, phosphorylated PI3K(p-PI3K), Akt, phosphorylated Akt(p-Akt), nuclear factor κB(NF-κB), and brain-derived neurotrophic factor(BDNF). Behavioral evaluation showed that Yueju Wan volatile oil could effectively control the decline of body mass and body temperature of depressed mice, reduce tail suspension and swimming immobility time, and enhance their preference for sucrose. Histopathological examination showed that Yueju Wan volatile oil could alleviate the neuronal damage in CA1 and dentate gyrus(DG) of the hippocampus of mice. ELISA and Western blot results showed that Yueju Wan volatile oil could significantly increase the protein expression levels of PI3K, Akt, and BDNF and significantly decrease the protein expression levels of AGEs, IL-1β, p-PI3K, p-Akt, and NF-κB in the hippocampus of mice. Furthermore, the p-PI3K/PI3K and p-Akt/Akt ratios were significantly decreased at medium and high doses. These findings suggest that the aromatherapy of Yueju Wan volatile oil can significantly improve reserpine-induced depression-like behavior in mice, which may be related to reducing the expression of neuronal membrane protein AGEs, reducing the phosphorylation levels of PI3K and Akt, inhibiting NF-κB entry into the nucleus, and alleviating the release of pro-inflammatory factors and nerve injury.

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.

Breast cancer has become the most prevalent malignant tumor among women, putting the health of women at serious risk. Screening for lead compounds in the active ingredients of plant that are effective and less toxic continues to be an important strategy for treating breast cancer. Gerbeloid J, a coumarin isolated from Gerbera piloselloides (L.) Cass., showed significant anti-cancer activity. But there is no report on the effect and mechanism of gerbeloid J on cycle and apoptosis of breast cancer. By using the CCK-8, clone formation, and PI staining assays, the effects of gerbeloid J on the proliferation of MCF-7 and MDA-MB-231 cells were assessed in this study. The effects of gerbeloid J on the apoptosis and mitochondrial function of MCF-7 and MDA-MB-231 cells were assessed using DAPI, Annexin V/TO-PRO-3, Rhod-2 AM, TMRM, DCFDA staining assays, and Western blot. The results demonstrated that gerbeloid J regulated the P21/CDC25C/CDK-1/cyclin B1 pathway and arrested the cell cycle at G2/M phase to suppressed the proliferation of MCF-7 and MDA-MB-231 cells. Additionally, gerbeloid J induced apoptosis through the stimulation of mitochondrial calcium excess, reduction of mitochondrial membrane potential, and promotion of ROS generation, and its mechanism was related to the activation of mitochondrial apoptotic pathway. In conclusion, by regulating the P21/CDC25C/CDK-1/cyclin B1 pathway and activating the mitochondrial apoptosis pathway, gerbeloid J could cause breast cancer cell cycle arrest and apoptosis, which might offer a promising candidate for the creation of new drugs against breast cancer.

OBJECTIVE: To analyze the characteristics of gene mutation and overexpression in newly diagnosed multiple myeloma (NDMM) patients. METHODS: Bone marrow cells from 208 NDMM patients were collected and analyzed. The gene mutation of 28 genes and overexpression of 6 genes was detected by DNA sequencing. Chromosome structure abnormalities were detected by fluorescence in situ hybridization (FISH). RESULTS: Gene mutations were detected in 61 (29.33%) NDMM patients. Some mutations occurred in 5 or more cases, such as NRAS, PRDM1, FAM46C, MYC, CCND1, LTB, DIS3, KRAS, and CRBN. Overexpression of six genes (CCND1, CCND3, BCL-2, CCND2, FGFR3, and MYC) were detected in 83 (39.9%) patients, and cell cycle regulation gene was the most common. Single nucleotide polymorphisms (SNP) changes were detected in 169 (81.25%) patients, the TP53 P72R gene SNP (70.17%) was the most common. Abnormality in chromosome structure was correlated to gene overexpression. Compared to the patients with normal chromosome structure, patients with 14q32 deletion showed higher proportion of CCND1 overexpression. Similarly, patients with 13q14 deletion showed higher proportion of FGFR3 overexpression, whereas patients with 1q21 amplification showed higher proportion of CCND2, BCL-2 and FGFR3 overexpression. CONCLUSION There are multiple gene mutations and overexpression in NDMM. However, there is no dominated single mutation or overexpression of genes. The most common gene mutations are those in the RAS/MAPK pathway and the genes of cyclin family CCND are overexpression.

ObjectiveTo explore the effect of health locus of control on the early rehabilitation after anterior cruciate ligament（ACL） reconstruction. MethodsFrom July 2019 to October 2019， a prospective cohort study of 155 ACL patients receiving reconstruction （male=124 and female=31） in our hospital was conducted. The general data questionnaire， MHLC-C， Tegner activity score， IKDC Score， Lysholm Score and Y-Balance Test were used for further analysis. The correlation between HLC and early rehabilitation after ACL reconstruction was explored by Wilcoxon signed-rank tests， correlation analysis and Logistics regression analysis. ResultsPositive correlations were found between the internality health locus of control （IHLC） and the IKDC score （r_3m=0.77， r_6m=0.70， P<0.001）， as well as the Lysholm scores （r_3m=0.68， r_6m=0.64， P<0.001） and the Tegner activity score （r_3m=0.24， r_6m=0.46， P<0.05） in 3 and 6 months after surgery， and higher IHLC score indicated a better y-balance test outcome［OR 95%CI=0.86（0.76， 0.97）， P=0.016］. Chance health locus of control （CHLC） was negatively correlated with the IKDC score （r_3m=-0.71， r_6m=-0.67， P<0.001）， the Lysholm score （r_3m=-0.49， r_6m=-0.43， P<0.001） and the Tegner activity score （r_3m=-0.22， r_6m=-0.35， P<0.05） in 3 and 6 months after surgery， and higher CHLC score indicated worse outcome of y-balance test ［OR 95%CI=1.26（1.12， 1.41）， P<0.001］. There was a negative correlation between the Powerful others health locus of control （PHLC） and the IKDC score （r_3m=-0.51， r_6m=-0.50， P<0.001）， the Lysholm scores （r_3m=-0.36， r_6m=-0.40， P<0.001）， but there was no correlation with the Tegner activity score in 3 and 6 months after surgery（P>0.05）. The risk of poor y-balance test increased by higher score of PHLC ［OR 95%CI=1.74（1.29， 2.34）， P<0.001］. ConclusionA significant correlation was found between the health locus of control and the early rehabilitation effect after ACL reconstruction. Higher internality health locus of control scores indicated a better rehabilitation outcome， while higher scores of external loci of control indicated higher risk of worse rehabilitation outcome.

Aim To study the mechanism of anti-plate- let aggregation of sorghum root active parts. Methods The effects of active fraction (WEAE-M 30%) from sorghum roots on platelet aggregation induced by collagen, thrombin and adenosine diphosphate were investigated in vitro. Western blot, enzyme-linked immunoas-say, flow cytometry and fluorescence techniques were used to explore the mechanism of the antiplatelet aggregation effect of WEAE-M 30% . Results WEAE-M 30% had a significant inhibitory effect on platelet aggregation induced by the three agonists mentioned above. The inhibitory effect on platelet aggregation induced by collagen was the most significant, with an inhibitory rate of (72. 91 ±2. 42)%. It was found that WEAE-M 30% had a significant inhibitory effect on the collagen- mediated platelet (IPVI signaling pathway protein Src, MAPK signaling pathway protein p38 and ERK phosphorylation. It also significantly inhibited the levels of ATP, P-selection and Ca2+ in platelets. Conclusions It is suggested that the mechanism of WE-AE-M 30% antiplatelet aggregation may be related to the inhibition of platelet activation pathway GPV1, MAPK and the release of typical platelet representative particles.

Objective: To evaluate the safety and clinical efficiency of holmium laser enucleation of the prostate (HoLEP) in the treatment of small-volume BPH (SBPH) complicated by severe lower urinary tract symptoms (LUTS). METHODS: We retrospectively analyzed the clinical data on 82 cases of SBPH with severe LUTS treated by HoLEP from January 2017 to December 2018. The patients were aged (65.5 ± 7.6) years, with a mean prostate volume of <40 ml, a total IPSS of 24.8 ± 4.6, a QOL score of 5.2 ± 0.8, the maximum urinary flow rate (Qmax) of (7.6 ± 3.7) ml/s, and a mean PSA level of (1.8 ± 1.4) μg/L. RESULTS: All the operations were successfully completed, the mean operation time averaging (30.2 ± 5.0) min, enucleation time (26.7 ± 5.6) min and comminution time (3.5 ± 1.1) min, and the enucleated tissue weighing (20.3 ± 4.9) g. After surgery, the bladders were irrigated for (3.5 ± 1.9) h, with (3.0 ± 1.7) L of rinse solution, and catheterization lasted (24.8 ± 9.7) h. Histopathology revealed moderate or severe lymphocytic infiltration in 69 cases (84.1%). At 6 months after operation, significant improvement was observed in the IPSS, QOL, Qmax and PSA level compared with the baseline (P < 0.05). To date, no urethral stricture-related reoperation was ever necessitated. CONCLUSIONS HoLEP is safe and effective for the treatment of SBPH complicated by severe LUTS and can be employed after adequate preoperative evaluation of the patient.《.
