ABSTRACT

Objective:To compare the application value of Caprini thrombosis risk assessment scale and Shanghai venous thrombosis risk factor scale in predicting venous thromboembolism in hospitalized maternal patients.Methods:This was a case-control study. A total of 67 pregnant women complicated with venous thromboembolism in the Obstetrics Department of Shandong Provincial Hospital Affiliated to Shandong First Medical University from January 2010 to September 2021 were retrospectively analyzed. And 144 pregnant women without venous thromboembolism in the same period were selected. Two venous thrombosis risk assessment tools were used to evaluate the pregnant women, and the predictive effectiveness and accuracy of the two assessment tools were compared.Results:The effects of the two risk assessment tools for venous thrombosis were different before and after delivery with statistical difference ( Z=8.15, 5.97, both P<0.01), but the Shanghai venous thrombosis risk factor scale (83.9%, 67.3%) was superior to Caprini thrombosis risk assessment scale (52.1%, 45.0%) in the accuracy of prenatal and postnatal prediction. The area under receiver operating characteristic curve showed that the Shanghai venous thrombosis risk factor rating scale (0.863) was significantly superior to the Caprini thrombosis risk assessment scale (0.748) after delivery. Conclusions:The Shanghai venous thrombosis risk factor scale is more valuable than the Caprini thrombosis risk assessment scale in the early risk identification of venous thromboembolism in pregnant women.

ABSTRACT

Evading or escaping from predators is one of the most crucial issues for survival across the animal kingdom. The timely detection of predators and the initiation of appropriate fight-or-flight responses are innate capabilities of the nervous system. Here we review recent progress in our understanding of innate visually-triggered defensive behaviors and the underlying neural circuit mechanisms, and a comparison among vinegar flies, zebrafish, and mice is included. This overview covers the anatomical and functional aspects of the neural circuits involved in this process, including visual threat processing and identification, the selection of appropriate behavioral responses, and the initiation of these innate defensive behaviors. The emphasis of this review is on the early stages of this pathway, namely, threat identification from complex visual inputs and how behavioral choices are influenced by differences in visual threats. We also briefly cover how the innate defensive response is processed centrally. Based on these summaries, we discuss coding strategies for visual threats and propose a common prototypical pathway for rapid innate defensive responses.

ABSTRACT

Tripterygium wilfordii is a valuable medicinal plant rich in biologically active diterpenoids, but there are few studies on the origins of these diterpenoids in its secondary metabolism. Here, we identified three regions containing tandemly duplicated diterpene synthase genes on chromosomes (Chr) 17 and 21 of T. wilfordii and obtained 11 diterpene synthases with different functions. We further revealed that these diterpene synthases underwent duplication and rearrangement at approximately 2.3-23.7 million years ago (MYA) by whole-genome triplication (WGT), transposon mediation, and tandem duplication, followed by functional divergence. We first demonstrated that four key amino acids in the sequences of TwCPS3, TwCPS5, and TwCPS6 were altered during evolution, leading to their functional divergence and the formation of diterpene secondary metabolites. Then, we demonstrated that the functional divergence of three TwKSLs was driven by mutations in two key amino acids. Finally, we discovered the mechanisms of evolution and pseudogenization of miltiradiene synthases in T. wilfordii and elucidated that the new function in TwMS1/2 from the terpene synthase (TPS)-b subfamily was caused by progressive changes in multiple amino acids after the WGT event. Our results provide key evidence for the formation of diverse diterpenoids during the evolution of secondary metabolites in T. wilfordii.

ABSTRACT

Triptolide has wide clinical applications due to its anti-inflammatory, anti-tumor and immunosuppressive activities. In this study, we investigated the effect of blocking isopentenyl pyrophosphate (IPP) translocation on the biosynthesis of triptolide by exogenously adding D,L-glyceraldehyde (DLG) to the suspension cells of Ttripterygium wilfordii at different stages (7 d, 14 d). Subsequently, the cell viability, biomass accumulation, triptolide contents, as well as the profiles of the key enzyme genes involved in the upstream pathway of triptolide biosynthesis, were analyzed. The results showed that IPP translocation is involved in the biosynthesis of triptolide. IPP is mainly translocated from the plastid (containing the MEP pathway) to the cytoplasm (containing the MVA pathway) in the early stage of the culture, but reversed in the late stage. Blocking the translocation of IPP affected the expression of key enzyme genes involved in the upstream pathway of triptolide, which in turn affected the accumulation of triptolide. Understanding the characteristics and mechanism of IPP translocation provides a theoretical basis for further promoting triptolide biosynthesis through synthetic biology.

ABSTRACT

Objective:To evaluate the effect of using a walking support band on the gait of stroke survivors.Methods:Sixty stroke survivors were randomly divided into a walking support band group ( n=20), an ankle foot orthosis (AFO) group ( n=20) and a conventional rehabilitation group ( n=20). All three groups received conventional rehabilitation therapy, while the AFO group members were additionally provided with an ankle-foot orthosis and the walking support band group members received training wearing a walking support band. Before and after 4 weeks of treatment, all three groups were evaluated using three-dimensional gait analysis. Results:A total of 57 patients finished the study. After the interventions, the average step speed, frequency and step length of the three groups had all increased significantly, while the average stride width, the percentage of double stance phase, unaffected and affected side stance phase, and the ratio between unaffected and affected side stance phase had all decreased significantly. After the intervention, the average step speed, frequency and length of the AFO and walking support band groups had increased significantly compared with the conventional rehabilitation group, while the average stride width of the AFO group, and the stride width, the percentage of double stance phase and unaffected side stance phase of the walking support band group had decreased significantly. After the treatment, the average percentages of double stance phase and unaffected side stance phase of the walking support band group had decreased significantly more than in the AFO group.Conclusions:A walking support band can significantly improve the abnormal gait of stroke survivors and is superior to an ankle-foot orthosis when combined with conventional rehabilitation therapy.

ABSTRACT

Sterol C24-methyltransferase (SMT) plays multiple important roles in plant growth and development. SMT1, which belongs to the family of transferases and transforms cycloartenol into 24-methylene cycloartenol, is involved in the biosynthesis of 24-methyl sterols. Here, we report the cloning and characterization of a cDNA encoding a sterol C24-methyltransferase from().(GenBank access number KU885950) is a 1530 bp cDNA with a 1041 bp open reading frame predicted to encode a 346-amino acid, 38.62 kDa protein. The polypeptide encoded by thecDNA was expressed and purified as a recombinant protein from() and showed SMT activity. The expression ofwas highly up-regulated incell suspension cultures treated with methyl jasmonate (MeJA). Tissue expression pattern analysis showed higher expression in the phellem layer compared to the other four organs (leaf, stem, xylem and phloem), which is about ten times that of the lowest expression in leaf. The results are meaningful for the study of sterol biosynthesis ofand will further lay the foundations for the research in regulating both the content of other main compounds and growth and development of

ABSTRACT

Objective To evaluate diagnostic value of the novel virtual touch tissue imaging quantification (VTIQ) technique of acoustic radiation force impulse (ARFI) shear wave elastography in the differential diagnosis between benign and malignant thyroid lesions. Methods From June to July 2014, the imaging data of 82 thyroid lesions in 75 patients proven by fine needle aspiration cytology (FNAC) biopsy on conventional ultrasound and VTIQ were retrospectively analyzed. The thyroid nodules were examined by conventional ultrasound firstly and then the lesions were classified by thyroid imaging report and data system (TI-RADS). The maximum, minimum, median and average of shear wave velocity (SWV) values were obtained from multiple SWV measurement under the VTIQ speed mode. The region of interest (ROI) was determined according to the VTIQ quality mode after the patients holding the breath. According to the FNAC cytology results, ROC curve were plotted to determine the most accurate SWV value and the cut-off value for differential diagnosis. Results According to the FNAC results, grading≥5 level was set as the positive results and FNAC<5 level as the negative results. There were 28 positive nodules and 54 negative nodules in 82 thyroid nodules. The positive rates of TI-RADS classification were consistent with the theoretical results. The SWVmax, SWVmin, SWVmedian, and SWVmean on VTIQ of negative and positive thyroid nodules were (3.2±0.6), (2.2±0.4), (2.7±0.4), (2.6±0.4) m/s, and (4.6±1.7), (3.1±0.8), (3.5±1.0), (3.6±1.1) m/s. There were significant differences between positive and negative thyroid nodules in SWVmax, SWVmin, SWVmedian, and SWVmean on VTIQ (t=3.53, 3.68, 3.32, 3.81, all P<0.01). Based on the area under curve of ROC, the SWVmean value in the nodule was the best value in comparison with other SWV values. The cut-off value of VTIQ mean was 2.9 m/s. According to ROC curve analysis, the sensitivity, specificity and Youden index for VTIQ were 70.6%, 88.5%, 0.59, respectively. Conclusion The study proved that VTIQ elastography technique plays an important role in differential diagnosis of thyroid nodules and the VTIQ SWVmean is the best parameter for differential diagnosis.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the relationship between expression of coiled-coil domain-containing protein 80(CCDC80) and obesity in serum and adipose tissues.</p><p><b>METHODS</b>A cross-sectional survey was conducted in a hospital in Tangshan in September 2010. 100 people including 78 healthy people and 22 with type-2 diabetes were recruited. Another 36 female patients with benign tumor of Obstetrics and Gynecology were also recruited. Demographic characteristics and serum samples were collected from all subjects, basic biochemical indicators were tested. All subjects were divided into 'Normal Weight' and 'Overweight and Obese' according to their BMI (BMI <24.0 kg/m(2); BMI≥24 kg/m(2)). Serum CCDC80 of the 100 subjects was detected by ELISA. Visceral and subcutaneous fat were derived from the other 36 female subjects, and Real-time PCR was used to detect CCDC80 mRNA expression in adipose tissues. Pearson correlation and multiple linear regression were used to analyze the correlation between serum or adipose CCDC80 expression and waist, BMI, and other biochemical indicators.</p><p><b>RESULTS</b>The age of 100 subjects was (52.9±8.4) years old. 44% of them were women (44 cases) and 56% of them were men (56 cases). After dividing them into three groups according to their BMI, covariance analysis were conducted, and age and gender were adjusted. The HDL-C level was significantly different among three groups (F = 10.73, P < 0.001): 'Overweight and obese combined with diabetes' group ((0.90±0.06) mmol/L)< 'Overweight and obese' group ((1.14±0.04) mmol/L) < 'Normal weight' group ((1.28±0.05) mmol/L). The adjusted expression of serum CCDC80 of the 100 subjects was (5.84±0.16) pg/ml, (5.81±0.98) pg/ml among men and (5.97±0.89) pg/ml among women, and there was no significant difference (t = -0.812, P = 0.419) between genders. ANOVA revealed that there was no significant differences of the expression of serum CCDC80 among three groups (F = 1.06, P = 0.351), 'Normal weight' group was (5.84±0.16) pg/ml, 'overweight and obese' group was (6.11±0.14) pg/ml, and 'Overweight and obese combined with diabetes' group was (5.84±0.19) pg/ml. The analysis showed that FBG had a negative correlation with serum CCDC80 (R(b) = -0.223, P = 0.026). Multivariate linear regression had a similar result, with 1 mmol/L increase of serum FBG, serum CCDC80 decreases for 0.24 pg/ml (β = -0.24, 95% CI: -0.21--0.02). There was also a negative correlation between serum CCDC80 and FBG in overweight and obese people (R(a) = -0.368, P = 0.013). Besides, CCDC80 mRNA was detected in both subcutaneous and visceral adipose tissue of 36 cases, the expression level was 0.06±0.02 for subcutaneous fat, was 0.05±0.04 for visceral fat, and the expression in visceral fat was lower (0.05±0.03) than that in subcutaneous fat (0.06±0.03) (t = 2.50, P = 0.025) among overweight and obese group. There was a negative correlation between waist and visceral CCDC80 mRNA expression (r = -0.472, P = 0.035).</p><p><b>CONCLUSION</b>This study suggested that CCDC80 may be involved in energy and insulin metabolism, and plays a protective role in obesity and diabetes.</p>

ABSTRACT

Staphylococcus aureus is a major cause of hospital-acquired infection. Because the bacteria are very easy to become resistant to antibiotics, vaccination is a main method against S. aureus infection. Clumping factor B (ClfB) is an adhesion molecule essential for S. aureus to colonize in the host mucosa and is regarded as an important target antigen. In this study, we successfully used Escherichia coli to express a segment encoding the N1-N3 regions of ClfB protein (Truncated-ClfB) cloned from S. aureus. The protein was purified by affinity and ion exchange chromatographies and gel filtration. Rabbits were immunized three times with purified Truncated-ClfB. After that, blood was collected to prepare serum which were then used for measurement of antibody level. Phagocytosis of S. aureus opsonized by the serum was determined by a flow cytometry. Results show that the serum IgG titer reached 1:640 000. Phagocytosed S. aureus by polymorphonuclear leukocytes were significantly more when the bacteria were opsonized by the serum from Truncated-ClfB immunized rabbits than those from no immunized group (P < 0.01). Therefore, the results indicated that Truncated-ClfB could be a promising vaccine candidate against S. aureus infection.

ABSTRACT

Objective To prospectively validate the feasibility and usefulness of the thyroid imaging reporting and data system (TI-RADS) suggested by Kwak. Methods According to the TI-RADS published in Radiology by Kwak et al in 2011, the TI-RADS score of 810 thyroid nodules in 415 patients whose pathologic diagnoses were available were categorized . According to TI-RADS and pathologic results, receiver operating characteristic (ROC) curve was plotted, and the probability of malignancy in each category was calculated. Results Eight hundred and ten pathologically proven thyroid nodules included 649 benign and 161 malignant lesions. Among them, 11 nodules were categorized as TI-RADS 2 (all benign nodules);370 nodules were categorized as TI-RADS 3 (368 benign nodules and 2 malignant nodules);150 nodules were categorized as TI-RADS 4a (143 benign nodules and 7 malignant nodules);116 nodules were categorized as TI-RADS 4b (87 benign nodules and 29 malignant nodules); 146 nodules were categorized as TI-RADS 4c (39 benign nodules and 107 malignant nodules);17 nodules were categorized as TI-RADS 5 (1 benign nodules and 16 malignant nodules). The area under the curve of TI-RADS was 0.89, and the probability of malignancy in nodules with a classiifcation of TI-RADS 2, 3, 4a, 4b, 4c and 5 was 0, 0.5%, 4.6%, 25.0%, 73.0%and 94.0%, respectively. Conclusions The TI-RADS suggested by Kwak has great diagnostic value in diagnosing thyroid nodules. The actual probability of malignancy conforms with the theoretical risk of malignancy.

ABSTRACT

Objective To investigate the features of intraductal papillary neoplasm of the bile duct (IPN-B) on baseline ultrasound and contrast-enhanced ultrasound (CEUS).Methods A retrospective analysis of the baseline ultrasound and CEUS in nine pathologically proven IPN-B lesions in eight patients.CEUS was performed with low mechanical index and continuous real-time imaging technique and the contrast agent of SonoVue.Results On conventional ultrasound,5 lesions were appeared as expansion of bile duct type,whose main features were cauliflower shape tumor (n =1) or papillary nodes (n =3) in expanded bile duct with rare blood supply;the other 3 lesions were appeared as complex cystic type,which contained cystic and solid components in the lesions.Many tiny anechoic areas were observed inside the solid lesions.Two lesions were rich in blood supply and another one was rare.All were communicated with adjacent slightly dilated bile duct.On CEUS,solid components of eight lesions appeared homogeneous (n =5) or heterogeneous (n =3) hyper-enhancement in the arterial phase and declined into hypo-enhancement in the portal and late phases.One lesion,on the contrary,was invisible on both conventional ultrasound and CEUS.Conclusions Understanding the ultrasound features of IPN-B is mandatory because of its low preoperative diagnosis rate on CEUS.IPN-B should be taken into consideration when cauliflower shape tumors or papillary nodules in expanded bile duct,as well as hyper-enhancement in the arterial phase and hypo-enhancement in the portal and late phases on CEUS,were demonstrated.
