Objective To investigate the effect of ultrasound-guided subcostal transverses abdominis plane (TAP) block with dexmedetomidine after laparoscopic radical operation. Methods 40 patients underwent laparoscopic radical operation for colorectal cancer were randomized into dexmedetomidine group (group DEX) and control group (group CON). All the patients received ultrasound-guided subcostal TAP block after operation, Group DEX with dexmedetomidine 1 μg/kg and 0.25% ropivacaine to 20 ml, and group CON with 0.25% ropivacaine 20 ml. All the patients were assessed with Ramsay scores and the pain at rest and on coughing were assessed with Visual Analogue Scale (VAS), 2, 6, 12, 24 and 24 hours after operation. The highest level and the duration of sensory blockade, the first time and the total times of pressing the analgesia pump in the first day after operation, and the requirements of sufentanil were recorded. First flatus time, first diet time and the length of hospital stay were compared. Results The scores of VAS were significantly less (P<0.001), and the Ramsay scores were more in the group DEX than in the group CON (P<0.01) 2, 6 and 12 hours after operation; with the longer time of sensory blockade (P<0.001), the later to first press the analgesia pump (P<0.001), the less frequence of pressing the analgesia pump (P<0.001), and less dosage of sufentanil (P<0.001). The first flatus time, first diet time were significantly earlier in the group DEX than in the group CON (P<0.001), with the less length of total hospital stay (P<0.001). Conclusion Dexmedetomidine can promote the anaesthesia of ultrasound-guided subcostal TAP block with ropivacaine and improve the recovery after laparoscopic radical operation.

WRKY transcription factors, one of the largest families of transcriptional regulators in plants, involve in multiple life activities including plant growth and development as well as stress responses. However, little is known about the types and functions of WRKY transcription factors in Catharanthus roseus, an important medicinal plant. In this study, we identified 47 CrWRKY transcriptional factors from 26 009 proteins in Catharanthus roseus, and classified them into three distinct groups (G1, G2 and G3) according to the structure of WRKY domain and evolution of the protein family. The expression profiling showed that these CrWRKY genes expressed in a tissue/organ specific manner. The 47 CrWRKY genes were clustered into three types of expression patterns. The first type includes the CrWRKYs highly expressed in flowers and the protoplast treated with methy jasmonate (MeJA) or yeast extraction (YE). The second type contains the CrWRKYs highly expressed in stem and hairy root. The third type represents the CrWRKYs highly expressed in root, stem, leaf, seedling and the hairy root treated by MeJA. Real time quantitative PCR was employed to further identify the expression patterns of the 16 selected CrWRKY genes in various organs, the MeJA-treated protoplasts and hairy roots of Catharanthus roseus, and similar results were obtained. Notably, the expresion of more than 1/3 CrWRKY genes were regulated by MeJA or YE, indicating that these CrWRKYs are likely involed in the signalling webs which modulate the biosynthesis of terpenoid indole alkaloid and plant responses to various stresses. The present results provide a framework for functional identification of the CrWRKYs and understanding of the regulation network of terpenoid indole alkaloid biosynthesis in Catharanthus roseus.

Objective:To study the relationship and the role of leptin in children with biliary atresia and hepatic fibrosis to provide a treatment basis for these patients.Methods:The clinical data of children with biliary atresia or congenital biliary dilatation (CBD) who underwent surgical treatment at the Department of General Surgery of Tianjin Children's Hospital from August 2019 to August 2021 were retrospectively analyzed. Of 31 children included in this study, there were 14 males and 17 females, with age of 60 (30, 63) d. Children with biliary atresia served as the study group ( n=26) and children with CBD served as the control group ( n=5). Leptin protein, α-smooth muscleactin (α-SMA) and phosphorylation of extracellular-regulated protein kinase 1/2 (p-ERK1/2) in liver tissues were detectd by immunohistochemistry (IHC). The expression level of leptin mRNA in liver tissues were detected by quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR). Results:The average optical density values of leptin protein, α-SMA protein and p-ERK1/2 protein in the liver tissues of children in the study group were significantly higher than the control group ( P<0.05). The expression levels of leptin, α-SMA and p-ERK1/2 in liver tissues of children with biliary atresia significantly increased with increase in fibrosis degree ( P<0.05). The expression level of leptin in liver tissues of children with biliary atresia was positively correlated with the liver fibrosis grade ( rs=0.876), α-SMA ( r=0.723) and p-ERK1/2 ( r=0.725) ( P<0.01). The results of qRT-PCR showed that the content of leptin mRNA in liver tissues of children with biliary atresia was significantly higher than that of children with CBD ( P<0.05). Conclusion:Expressions of leptin increased with aggravation of degrees of hepatic fibrosis in biliary atresia. Leptin may be involved in activation of HSCs through the ERK1/2 signaling pathway in the process of hepatic fibrosis due to biliary atresia.

Objective:To investigate the labial surface angle and Collum angle of anterior teeth using cone-beam computed tomography (CBCT), and to provide guidance for proper setting of torque for avoiding alveolar fenestration and dehiscence.Methods:CBCT data of 200 patients (66 males, age ranging from 18 to 40 years, with average 26.7 years) were screened and imported into Invivo 5.4, the middle labio-lingual sections of anterior teeth were obtained, and the Collum angle and labial surface angle were measured respectively. One-way ANOVA was used to analyze the discrepancies of the two measurements among teeth. Pearson correlation analysis was performed to detect the association between the two measurements.Results:The Collum angles (labial surface angles) in upper central incisor, lateral incisor, canine and lower central incisor, lateral incisor and canine were 0.17±5.11° (15.50±2.91°), -5.67±5.74° (15.52±3.50°), -5.56±4.67° (20.07±3.66°), -3.97±4.49° (14.40±3.20°), -6.50±4.03° (14.76±3.25°), -3.70±4.91° (18.27±3.07°) respectively; the positive Collum angles indicated the lingually bent root relative to crown, while the negative indicated the labially bent root. The labial surface angles in upper and lower canine were significantly larger than that of intra-arch central and lateral incisors ( P<0.001). On the contrary, no significant differences were detected between central and lateral incisors in the maxilla and mandible ( P>0.05, P>0.05). Moreover, except for the maxillary central incisor, the Collum angle and labial surface angle were positively correlated. Conclusions:The values of Collum angle among anterior teeth are significantly different, and the obvious lingual-bent root are more likely accompanied with the greater labial surface curve, which might cause variable torqueing and be necessary to elevate before treatment.
