ABSTRACT

In this study, emotional stress-induced herpes simplex virus type 1(HSV-1) susceptibility model was employed to simu-late the pathological state of " depression-induced liver fire", and the protection effect of Qingre Xiaoyanning(QX) in clearing liver fire was investigated. BALB/c mice were randomly divided into a normal group, a HSV-1 group, a restraint stress + HSV-1 group,low-(0. 658 g·kg~(-1)) and high-dose(1. 316 g·kg~(-1)) QX groups, and an acyclovir group. Except for the normal group and the HSV-1 group, the mice in other groups received daily restraint stress for 6 h from day 3 of medication. On day 9 of medication, mice were anesthetized by isoflurane and infected intranasally with HSV-1. Survival rate, weight change, encephalitis symptoms, and eye injury of mice were recorded for 14 d after virus infection. Hematoxylin-eosin(HE) staining and immunohistochemical staining were used to detect pathological changes and HSV-1 antigen distribution. Plaque assay was performed to detect the titer of HSV-1. The protein ex-pression of ICP27 in the mouse brain was detected by Western blot. The experimental results showed that QX could increase the survival rate of HSV-1-infected mice loaded with emotional stress(P<0. 001), reduce the titer of HSV-1 in the mouse brain(P<0. 01), relieve brain inflammation(P<0. 05) and eye injury(P<0. 05), down-regulate the expression of ICP27 related to HSV-1(P<0. 05), and decrease the distribution of HSV-1 antigen in the mouse brain. The results demonstrated that QX significantly reduced the susceptibility to HSV-1 induced by emotional stress, which is expected to provide a theoretical basis for the treatment and preven-tion of HSV-1 infection and promote the clinical development and application of Chinese medicine effective in clearing liver fire.

ABSTRACT

Objective:To investigate the power and prenatal diagnosis strategies of cell-free fetal DNA (cffDNA) testing for chromosomal aneuploidy screening apart from trisomy-13/18/21.Methods:This study collected the clinical data of three cases at high risk of trisomy-16 indicated by cffDNA testing in Hunan Provincial Maternal and Child Health Care Hospital from March 2019 to March 2020. Results of the conventional G-banding karyotype analysis of amniotic fluid, single nucleotide polymorphism array (SNP-array) and low-coverage massively parallel copy number variation sequencing (CNV-seq) of placenta/fetal skin samples were analyzed.Results:(1) cffDNA testing results suggested that case 1-3 were at high risk of trisomy-16 and the Z values of chromosome 16 were 20.57, 24.88 and 17.87, respectively. (2) Karyotype analysis of amniotic fluid samples did not identify any abnormalities in Case 1 and 2, while SNP-array revealed a 19.2 Mb and 23.0 Mb heterozygous deletion at 16p13.3p12.3 and 16q22.1q24.3 in Case 1, and a 16.0 Mb loss of heterozygosity at 16q22.3q24.3 in Case 2. Case 3 had a mosaicism karyotype of 47,XY,+16[3]/46,XY[97] and SNP-array analysis showed no heterozygous deletion greater than 5 Mb or copy number variation. (3) Ultrasonography indicated fetal growth restriction in Case 1 and 2 and fetal death in Case 3. All three pregnancies were terminated. CNV-seq analysis of placental tissue in the center of both fetal and maternal side revealed mosaic trisomy 16, with the copy numbers of chromosome 16 of 2.56/2.70, 2.73/2.82, 2.80/2.81, respectively. However, no copy number variation was detected in Case 1 or 2 by CNV-seq analysis of fetal skin tissues. Conclusions:cffDNA testing has a certain power in detecting trisomy-16 apart from trisomy-13/18/21. For high-risk cases of trisomy-16 indicated by cffDNA testing, SNP-array analysis combined with karyotype analysis is suggested to rule out low-level mosaicism and loss of heterozygosity.

ABSTRACT

Objective:To investigate the therapeutic effect of polydatin on ulcerative colitis (UC) in mice and its regulation of protein kinase C<italic>θ</italic>(PKC<italic>θ</italic>)/signal transducer and activator of transcription 3(STAT3) signaling on T helper cell 17(Th17) and its mechanism in the treatment of UC. Method:The 32 male C57BL/6 mice were randomly divided into normal group, model group, polydatin group (0.045 g·kg<sup>-1</sup>) and sulfasalazine group (0.5 g·kg<sup>-1</sup>). The UC model was established by giving 3% dextran sodium sulfate (DSS) solution to free drinking water in mice. Polydatin and sulfasalazine groups were given by gavage 0.5 h before modeling for 7 days. The normal group and model group were given the same amount of normal saline. After the last administration, the colonic tissue was taken and hematoxylin-eosin (HE) was used to observe the pathological changes of colonic tissue. Flow cytometry was used to detect the proportion of Th17 in the lamina propria of colonic mucosa. The expression of interleukin-17A (IL-17A) in serum was detected by enzyme-linked immunosorbent assay (ELISA). Polydatin was added to CD4<sup>+ </sup>T cells purified from spleen of C57BL/6 mice by magnetic-activated cell sorting (MACS) under the stimulation of cell stimulation cocktail <italic>in vitro </italic>in order to detect its impact on PKC<italic>θ</italic> and STAT3 phosphorylation. Result:Compared with normal group, the body weight was significantly decreased, and disease activity index (DAI) scores of the model group was significantly increased (<italic>P</italic><0.01), the colonic mucosal epithelium was damaged and inflammatory cells infiltration in the mucosa and submucosa was obvious, the proportion of Th17 in the lamina propria of colonic mucosa was significantly increased (<italic>P</italic><0.01), and the content of serum IL-17A was significantly increased (<italic>P</italic><0.01). Compared with the model group, the weight and DAI score of polydatin and sulfasalazine groups were significantly improved (<italic>P</italic><0.01), the degree of colon tissue damage was significantly improved, the proportion of Th17 in colon mucosa lamina propria was significantly decreased (<italic>P</italic><0.01), and the content of IL-17A in serum was significantly decreased (<italic>P</italic><0.01). <italic>In vitro</italic> experiments showed that polydatin could significantly inhibit the phosphorylation of PKC<italic>θ</italic> and STAT3 in Th17 (<italic>P</italic><0.01) as well as IL-17A secretion. Conclusion:Polydatin can improve the ulcerative colitis in mice via inhibiting the phosphorylation of PKC<italic>θ</italic> and STAT3 to preclude IL-17A secreting in Th17.

ABSTRACT

Objective:To explore the protective effect of Gegen Qinliantang on the intestinal mucosal epithelial barrier function of ulcerative colitis (UC) mice, and to explore its mechanism of action in the treatment of ulcerative colitis via matrix metallopeptidase-9 (MMP-9)/p38 mitogen-activated protein kinase (p38 MAPK) signaling pathway. Method:The 48 female C57BL/6 mice were randomly divided into normal group, model group, sulfasalazine group (0.3 g·kg<sup>-1</sup>) and Gegen Qinliantang high, medium and low dose groups (2.84,1.42,0.71 g·kg<sup>-1</sup>). The UC murine model was established by 3% dextran sulfate sodium (DSS). Gegen Qinliantang and sulfasalazine were intragastrically administered on the 8<sup>th</sup> day after the model was established for 7 days, and the normal group was treated with the same amount of normal saline. Colon tissues were collected after the last administration, and the pathological changes of colon tissues were detected by hematoxylin-eosin (HE) staining. The expression of tight junction (TJ) proteins such as Occludin and zonula occludens-1(ZO-1) in colon tissues was detected by immunohistochemistry (IHC), and the expression levels of tumor necrosis factor-alpha (TNF-<italic>α</italic>), interleukin-1<italic>β</italic> (IL-1<italic>β</italic>), and MMP-9 mRNA in colon tissues were detected by Real-time polymerase chain reaction (Real-time PCR). The expression of phosphorylated p38 MAPK (p-p38 MAPK), p38 MAPK and MMP-9 protein in colon tissues was detected by Western blot. Result:Compared with normal group, the body weight of mice decreased (<italic>P</italic><0.01) and disease activity index (DAI) score increased significantly (<italic>P</italic><0.01) in model group, the colon tissues of the model group were damaged more obviously, the expression of occludin and ZO-1 proteins in model group was significantly reduced (<italic>P</italic><0.01), and the relative expression levels of TNF-<italic>α</italic>, IL-1<italic>β</italic>, and MMP-9 mRNA in model group were significantly increased (<italic>P</italic><0.01), the expression of p-p38 MAPK and MMP-9 in model group was significantly increased (<italic>P</italic><0.01). Compared with model group, the body mass and DAI score of the sulfasalazine group and Gegen Qinliantang group were significantly improved (<italic>P</italic><0.05,<italic>P</italic><0.01), the colonic tissues damage were significantly improved, and the expression of Occludin and ZO-1 protein was significantly increased (<italic>P</italic><0.05,<italic>P</italic><0.01), the relative expression levels of TNF-<italic>α</italic>, IL-1<italic>β</italic>, and MMP-9 mRNA were significantly decreased (<italic>P</italic><0.01), and the expression of p-p38 MAPK and MMP-9 was significantly decreased (<italic>P</italic><0.01). The changes in the middle dose group were the most obvious among the various dose groups of Gegen Qinliantang. Conclusion:Gegen Qinliantang repairs the intestinal mucosal barrier function by inhibiting the expressions of MMP-9 and inflammatory cytokines such as TNF-<italic>α</italic> and IL-1<italic>β</italic>, blocking the activation of the p38 MAPK signaling pathway, and increasing the expressions of tight junction protein.

ABSTRACT

@#The effect of sodium salicylate on the endogenous metabolism of hair cell-like cells (HEI-OC1).of mice was analyzed based on liquid chromatography-quadrupole time of flight mass spectrometry (LC-Q-TOF/MS).Firstly, HEI-OC1 cells were treated with different concentrations of sodium salicylate, and cell survival was examined by the CCK-8 method. Next, sodium salicylate was administered for different duration to observe the changes in cell morphology. Inter-group differential metabolites were screened out, and the associated metabolic pathways were analyzed based on metabonomic technology.Results showed that sodium salicylate could significantly inhibit the survival rate of HEI-OC1 cells, and that, as the concentration increased, the inhibitory effect became stronger. Also, the cell morphology could be elongated after administration and return to normal after withdrawal.Eighteen differential metabolites such as orotic acid, uridine and aspartic acid were screened out after treatment of sodium salicylate, which mainly involving two possible metabolic pathways, namely the metabolism of alanine, aspartic acid and glutamic acid, and that of pyrimidine.In summary, the application of metabolomics technology to evaluate the effect of sodium salicylate on hair cells from the microscopic perspective can provide new ideas for the study of sodium salicylate ototoxicity and development of tinnitus.

ABSTRACT

Prostate cancer is one of the common malignant tumors of male urogenital system, and the incidence of prostate cancer in China has increased significantly in the past decade. At present, endocrine therapy based on androgen blockade is the main method of clinical treatment except radical surgery and radiotherapy/chemotherapy for prostate cancer. However, the clinical benefit can only be obtained in the early stage of treatment, and nearly 90% of patients will develop to the castration resistance, and among them, nearly 90% of patients will have bone metastasis. The quality of life decreases sharply with the progression of disease for patients. In addition to the androgen signal pathway, studies have shown that many other oncogenic signal pathways have involved in the development of castration resistance, including classic cancer signaling pathways, immune and inflammatory signaling pathways, etc. Understanding the mechanism of androgen independent signal pathway in the formation of castration resistance will help to understand the off-target effect of androgen blocking therapy and introduce new treatment targets or strategies to get rid of the "no drug available" dilemma for clinical treatment of castration resistance.

ABSTRACT

Anxiety disorders are one of the most common mental disorders in adults, the cause of which derives from a combination of genetics and environmental factors. A series of animal models have been established according to their pathogenesis to measure the level of anxiety or induce anxiety only, and these models have been widely applied in the non-clinical evaluation of anxiolytics. In this review, we present the current trends in the study of anxiety disorders and summarize typical non-clinical anxiety animal models, including models that both measure anxiety levels and induce anxiety, and models that induce anxiety only. This review summarizes the important issues in standardized non-clinical research of anxiety disorders and proposes criteria for the selection of an appropriate R&D model.

ABSTRACT

OBJECTIVE@#This study tests whether long-term intake of Allium tuberosum (AT) can alleviate pulmonary inflammation in ovalbumin (OVA)-induced asthmatic mice and evaluates its effect on the intestinal microbiota and innate lymphoid cells (ILCs).@*METHODS@#BALB/c mice were divided into three groups: phosphate buffer saline, OVA and OVA + AT. The asthmatic murine model was established by sensitization and challenge of OVA in the OVA and OVA + AT groups. AT was given to the OVA + AT group by oral gavage from day 0 to day 27. On day 28, mice were sacrificed. Histopathological evaluation of lung tissue was performed using hematoxylin and eosin, and periodic acid-Schiff staining. The levels of IgE in serum, interleukin-5 (IL-5) and IL-13 from bronchoalveolar lavage fluid (BALF) were measured by enzyme-linked immunosorbent assay. The ILCs from the lung and gut were detected by flow cytometry. 16S ribosomal DNA sequencing was used to analyze the differences in colon microbiota among treatment groups.@*RESULTS@#We found that long-term intake of AT decreased the number of inflammatory cells from BALF, reduced the levels of IL-5 and IL-13 in BALF, and IgE level in serum, and rescued pulmonary histopathology with less mucus secretion in asthmatic mice. 16S ribosomal DNA sequencing results showed that AT strongly affected the colonic bacteria community structure in asthmatic mice, although it had no significant effect on the abundance and diversity of the microbiota. Ruminococcaceae and Desulfovibrionaceae were identified as two biomarkers of the treatment effect of AT. Moreover, AT decreased the numbers of ILCs in both the lung and gut of asthmatic mice.@*CONCLUSION@#The results indicate that AT inhibits pulmonary inflammation, possibly by impeding the activation of ILCs and adjusting the homeostasis of gut microbiota in asthmatic mice.

ABSTRACT

To systematically evaluate the clinical efficacy and safety of Compound Danshen Dripping Pills combined with conventional antihypertensive drugs in the treatment of hypertensive left ventricular hypertrophy. China National Knowledge Infrastructure(CNKI), Wanfang, VIP, PubMed, EMbase, Cochrane Library, Ovid and Web of Science databases were searched by computer to retrieve the randomized controlled trials(RCTs) of Compound Danshen Dripping Pills combined with conventional antihypertensive drugs in the treatment of hypertensive left ventricular hypertrophy from the establishment of databases to July 2020. After two researchers performed data retrieval, data extraction, and risk assessment of bias, they used RevMan 5.3 software for Meta-analysis. A total of 10 RCTs were included, with a total of 979 patients. Meta-analysis results showed that in terms of interventricular septal thickness(MD=-0.70, 95%CI[-1.15,-0.24], P=0.003), left ventricular posterior wall thickness(MD=-0.81, 95%CI[-1.41,-0.21], P=0.008), left ventricular mass index(MD=-8.75, 95%CI[-17.40,-0.10], P=0.05), systolic blood pressure(MD=-8.97, 95%CI[-13.46,-4.48], P<0.000 1), diastolic blood pressure(MD=-5.87, 95%CI[-8.39,-3.34], P<0.000 01) and left ventricular end-diastolic diameter(MD=-1.73, 95%CI[-2.38,-1.08], P<0.000 01), Compound Danshen Dripping Pills combined with conventional antihypertensive drugs was superior to conventional antihypertensive drugs. In terms of left ventricular ejection fraction(MD=0.41, 95%CI[-0.74, 1.55], P=0.49), there was no statistical difference in treatment between the two groups. Because of the small amount of literatures included in the safety aspect, it is impossible to give an accurate conclusion. The GRADE score showed that the level of evidence was low and extremely low. The results show that the Compound Danshen Dripping Pills combined with conventional antihypertensive drugs may effectively improve the clinical efficacy for hypertensive ventricular hypertrophy, and the safety needs to be further explored. Due to the low quality of the included literatures, more high-quality RCTs are needed for verification.

ABSTRACT

Objective:To understand the current status of iodine deficiency disorders in children aged 8 - 10 years in Beihai, Guangxi, and to provide evidence for prevention and treatment of the disease.Methods:According to the "National Iodine Deficiency Disorders Surveillance Program" (2016 edition) and the "2016 - 2018 Beihai Iodine Deficiency Disorders Surveillance Program", Beihai was divided into administrative regions by stratified multi-stage sampling method in 2016 - 2018. Each district and county was divided into five parts according to directions: east, west, south, north and middle. One primary school was selected in each direction and 40 non-boarding students aged 8 - 10 years were selected from each primary school. Urine samples and edible salt samples were collected from children to detect urinary iodine and salt iodine contents. Thyroid volume of children was determined by B-ultrasound method, and the rate of goiter was calculated.Results:A total of 800 children aged 8 - 10 years were investigated, including 200 in 2016, 200 in 2017, and 400 in 2018. The ratio of male to female was 1.08:1.00 (415/385); the median salt iodine of children aged 8 - 10 years was 19.7 mg/kg; the edible rate of qualified iodized salt was 54.4% (435/800). The median urinary iodine of children aged 8 - 10 years in Beihai was 154.3 μg/L. The median urinary iodine of children aged 8, 9 and 10 years were 182.0, 141.9, 163.3 μg/L, respectively. The median urinary iodine of boys (164.3μg/L) was higher than that of girls (140.0 μg/L, Z = - 3.765, P < 0.05); there was a difference in the median urinary iodine between children aged 8 - 10 years in different regions ( H = 33.621, P < 0.05), and Tieshangang District had the lowest (117.6 μg/L); the median urinary iodine of 314 people was in the appropriate range (100 - < 200 μg/L), accounting for 39.3% (314/800). The total thyroid goiter rate was 1.1% (9/800) in children aged 8 - 10 years; the thyroid goiter rate was different in children from different regions ( P < 0.05), and the thyroid goiter rate (3.5%, 7/200) in children aged 8 - 10 years in Haicheng District was higher than that in other areas. Conclusions:The iodine nutrition status of children aged 8 - 10 years in Beihai is appropriate. Beihai should continue to adhere to salt iodization to prevent and treat iodine deficiency disorders, and take measures to adapt to local conditions and accurately supplement iodine for children aged 8 - 10 years in different districts and counties.

ABSTRACT

Objective:The phase separation of Baihutang was carried out. The content of mangiferin,new mangiferin,calciumion,glycyrrhizin and ammonium glycyrrhizinate in the solution phase,the nano phase and the precipitated phase of Baihutang were measured,so as to define the effect of nanometer particles of Baihutang on the growth of active components,and explain the mechanisms of Baihutang in potent detoxification and heat removal. Method:The phase separation of Baihutang was performed by high-speed centrifugation and dialysis. The contents of mangiferin,new mangiferin,glycyrrhizin and ammonium glycyrrhizinate in Baihutang were determined by HPLC. Chromatographic column Diamonsil C18 (4.6 mm×250 mm,5 μm) was adopted, with acetonitrile-25 mmol·L-1 potassium dihydrogen phosphate solution as the mobile phase, and eluted in a gradient mode. The detection wavelength was 257 nm,the column temperature was 30 ℃,and the flow rate was 1.0 mL·min-1. EDTA-2Na solution was used to calibrate the calcium concentration in different phase states of Baihutang. Result:1 mL Baihutang nanoparticles contained 483.00 μg new mangiferin,1 068.88 μg mangiferin,219.93 μg glycyrrhizin and 187.10 μg ammonium glycyrrhizin,and the content of new mangiferin and mangiferin accounted for 89.4% and 89.9% respectively in 1 mL Baihutang. The new mangiferin and mangiferin in the nano phase were 230.0 and 23.3 times the true solution,and 8.5 and 14.4 times of the precipitation,respectively. The content of calcium ions in Baihutang in the nano phase was higher,accounting for 86.9% of Baihutang,and the content of calcium ions in Baihutang and Baihutang in the nano phase was higher than that in gypsum group. Conclusion:The content of main components in Baihutang in nanometer phase is significantly higher than that in other phases. The nanoparticles of Baihutang have a solubilizing effect on the main antipyretic components, such as mangiferin,mangiferin and calcium ions as well as the antitoxic components glycyrrhizic acid and glycyrrhizic acid. The mechanism of action of Baihutang is related to the formation of nanoparticles.

Objective::To compare the effect of different medicinal parts of Nandina domestica in reducing toxicity of anti-tumor drug arsenic trioxide, so as to provide the scientific basis for its further development and application. Method::Chronic arsenic trioxide poisoning model was used in this paper. Totally 56 SD rats were randomly divided into normal group, model group (arsenolite 40 mg·kg-1), sodium 2, 3-dimercapto-1-propanesulfonate group (sodium 2, 3-dimercapto-1-propanesulfonate 25 mg·kg-1+ arsenolite 40 mg·kg-1), Nandinae Radix group (Nandinae Radix 20 g·kg-1+ arsenolite 40 mg·kg-1), Nandinae Caulis group (Nandinae Caulis 20 mg·kg-1+ arsenolite 40 mg·kg-1), Nandinae Folium group (Nandinae Folium 20 g·kg-1+ arsenolite 40 mg·kg-1), and Nandinae Fructus group (Nandinae Fructus 20 g·kg-1+ arsenolite 40 mg·kg-1). The intragastric administration lasted for 10 days. After the last administration, urine was collected within 24 hours, serum, kidney and liver tissue samples were collected after operation, and serum creatinine (SCr) and urine creatinine (UCr) levels were measured, in order to calculate endogenous creatinine clearance rate (CCr). At the same time, the levels of malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) in liver and kidney of rats in each group were detected. Some kidneys and livers were fixed with formaldehyde, and the histopathological changes were observed under microscope after hematoxylin-eosin staining. Result::Compared with the model group, the rats in combination group of Nandinae Radix, Nandinae Caulis, Nandinae Fructus have a heavier body mass (P<0.01), the kidney coefficient was lower (P<0.01), the levels of UCr and CCr were significantly increased (P<0.01), the content of MDA in renal tissue was decreased significantly (P < 0.01), the level of MDA in liver tissue was decreased (P < 0.05), whereas the activities of SOD and CAT were significantly increased (P<0.01), the pathological damage of liver and kidney was alleviated. There was no significant difference in the activity of SOD in the liver between the Nandinae Folium combination group and the model group, but the changes of the other indexes were consistent with those of the above three groups. Conclusion::Nandinae Radix, Nandinae Caulis, Nandinae Fructus have significant protective effects on liver and kidney toxicity induced by arsenic trioxide oxidative stress, and Nandinae Folium was the least effective among them.

ABSTRACT

Objective::To study the effect of total alkaloids of Nandina domestica in attenuating arsenic trioxide, and analyze chemical constituents of alkaloids extract of Nandina, in order to provide the theoretical basis for studying the effect of N. domestica in attenuating arsenic trioxide with alkaloids extract of N. domestica as effective fraction. Method::The model of acute liver injury induced by arsenic trioxide was used to compare the effects on heart and liver functions of mice between arsenic trioxide alone and total alkaloids of N. domestica combined with arsenic trioxide. The detoxification of total alkaloids on arsenic trioxide was evaluated based on biochemical parameters and pathological report. Peakview (Version1.2, AB SCIEX) software was used to process the mass spectrometry data of total alkaloids of N. domestica. The structures of determined compounds were identified by molecular weight of compound (molecular formula), secondary fragments, chromatographic peak retention and literature information. Result::Among biochemical indicators, creatine kinase(CK), lactate dehydrogenase(LDH), blood urea nitrogen(BUN), malondialdehyde(MDA), alanine aminotransferase(ALT) and amino transferase of aspartate(AST) of the arsenic trioxide group were increased, while elimination rates of Na+ -K+ -adenosine triphosphate(ATP), superoxide dismutase(SOD), catalase(CAT) and serum creatinine(SCr) were decreased, compared with those of the combination group. CK and LDH of the alkaloids extract group were more obviously increased than those of the N. domestica extract group, but with no remarkable difference. In histomorphometric examination, edema of mouse heart cells was improved, and some kidney and liver damages in rats were alleviated. Totally 25 alkaloids of alkaloid extract were identified. Among them, 18 were known, and 7 were unknown, including 3 structural types, in which apomorphine alkaloids were mostly. Conclusion::Heart, kidney and liver damage degrees of the combination group were significantly alleviated compared with the arsenic trioxide group. The total alkaloids fraction extracted and purified have a significant attenuation in arsenic trioxide toxicity. The detoxification of total alkaloids extract was equal to that of N. domestica extract. Furthermore, apomorphine alkaloids, such as nantenine and domesticine, can be used as index components to establish a quality control method for total alkaloids.

ABSTRACT

Blood-brain barrier (BBB) breakdown and the associated microvascular hyperpermeability are hallmark features of several neurological disorders, including traumatic brain injury (TBI). However, there is no viable therapeutic strategy to rescue BBB function. Tissue inhibitor of metalloproteinase-1 (TIMP1) has been considered to be beneficial for vascular integrity, but the molecular mechanisms underlying the functions of TIMP1 remain elusive. Here, we report that TIMP1 executes a protective role on neuroprotective function ameliorating BBB disruption in mice with experimental TBI. In human brain microvessel endothelial cells (HBMECs) exposed to hypoxia and inflammation injury, the recombinant TIMP1 (rTIMP1) treatment maintained integrity of junctional proteins and trans-endothelial tightness. Mechanistically, TIMP1 interacts with CD63/integrin 1 complex and activates downstream FAK signaling, leading to attenuation of RhoA activation and F-actin depolymerization for endothelial cells structure stabilization. Notably, these effects depend on CD63/integrin 1 complex, instead of the MMP-inhibitory function. Together, our results identified a novel MMP-independent function of TIMP1 in regulating endothelial barrier integrity. Therapeutic interventions targeting TIMP1 and its downstream signaling may be beneficial to protect BBB function following brain injury and neurological disorders.

ABSTRACT

OBJECTIVE@#To carry out prenatal diagnosis for a fetus with high risk predicted by non-invasive prenatal testing (NIPT).@*METHODS@#Next-generation sequencing (NGS) was used to analyze free fetal DNA (ffDNA) in the maternal plasma. Chromosomal karyotyping and single nucleotide polymorphism array (SNP-array) were used to ascertain copy number variation in the fetus and its parents.@*RESULTS@#SNP-array analysis and chromosomal karyotyping revealed that the fetus had a 15.018 Mb duplication at 4q34.1q35.2 and a 7.678 Mb duplication at 21q11.2q21.1, which were derived from a t(4;21)(q34.1;q21.1) translocation carried by its mother.@*CONCLUSION@#NIPT is capable of detecting submicroscopic chromosomal abnormalities of the fetus. Combined use of genetic techniques, in particular SNP-array, is crucial for the diagnosis of partial trisomy 21q in this case.
