ABSTRACT
Human adipose-derived stem cells (hASCs) are a promising cell type for bone tissue regeneration. Circular RNAs (circRNAs) have been shown to play a critical role in regulating various cell differentiation and involve in mesenchymal stem cell osteogenesis. However, how circRNAs regulate hASCs in osteogenesis is still unclear. Herein, we found circ_0003204 was significantly downregulated during osteogenic differentiation of hASCs. Knockdown of circ_0003204 by siRNA or overexpression by lentivirus confirmed circ_0003204 could negatively regulate the osteogenic differentiation of hASCs. We performed dual-luciferase reporting assay and rescue experiments to verify circ_0003204 regulated osteogenic differentiation via sponging miR-370-3p. We predicted and confirmed that miR-370-3p had targets in the 3'-UTR of HDAC4 mRNA. The following rescue experiments indicated that circ_0003204 regulated the osteogenic differentiation of hASCs via miR-370-3p/HDAC4 axis. Subsequent in vivo experiments showed the silencing of circ_0003204 increased the bone formation and promoted the expression of osteogenic-related proteins in a mouse bone defect model, while overexpression of circ_0003204 inhibited bone defect repair. Our findings indicated that circ_0003204 might be a promising target to promote the efficacy of hASCs in repairing bone defects.

Repairing glans dehiscence after failed hypospadias repair is challenging for pediatric surgeons. Here, we introduced and evaluated a newly modified Mathieu technique, Mathieu combined tunnel (MCT), which involves multiple custom-designed flaps for the shortage of flap source material after repeated operations; we also constructed a tunnel to avoid the glans incision that may carry new risks of dehiscence. This retrospective study included 26 patients who were consecutively admitted to the First Affiliated Hospital of Sun Yat-Sen University (Guangzhou, China) for glans dehiscence repair after failed hypospadias repair from October 2014 to October 2020; sixteen patients underwent surgery using the MCT (MCT group) and ten patients underwent surgery using the tubularized incised plate (TIP) technique (TIP group). The operative time, blood loss, postoperative complications, normal urethral meatus rate, success rate, and Hypospadias Objective Penile Evaluation (HOPE) score were compared between the two groups. The MCT group achieved an overall satisfactory penile appearance and voiding function, with a higher rate of normal urethral meatus (15/16, 93.8%) and a lower rate of glans dehiscence (1/16, 6.2%), compared with the TIP group (70.0% and 30.0%, respectively). However, these differences were not statistically significant, possibly because of the limited number of patients (all P > 0.05). Mean postoperative HOPE scores were similar in the MCT group (mean ± standard deviation: 8.83 ± 0. 89) and TIP group (8.94 ± 0.57) (P > 0.05). No significant differences were found between the two groups in terms of blood loss and success rate, nor in the rates of various complications (e.g., fistula, urethral stricture, and glans dehiscence). In conclusion, the MCT technique appears to be feasible and reliable for repairing glans dehiscence after failed hypospadias repair.

Crohn's disease (CD) is a chronic nonspecific inflammatory bowel disease that can involve the whole digestive tract. At present, the pathogenesis is believed to be mainly related to environment, genetics and intestinal microecology changes. Compared with healthy people, CD patients demonstrate different degrees of flora imbalance in the digestive tract, and the flora composition varies across different regions. In recent years, reconstruction of gastrointestinal microecological balance has become the focus of research. Fecal microbiota transplantation as a new treatment strategy has been gradually applied in clinical practice. Here we reviewed the changes of flora across different regions of digestive tract in patients with CD and the relevant pathogenic mechanism, as well as the progress of fecal microbiota transplantation in the treatment of CD.
ABSTRACT
Crohn's disease (CD) is a chronic nonspecific intestinal inflammatory disease with unclear etiology and pathogenesis. At present, it is believed that CD can cause different degrees of metabolic abnormalities, and that the related metabolites also play an important role in the development and progression of the disease. In recent years, metabonomics is becoming more and more well-developed and has provided guidance for clinicians on rational nutritional support. Here is a review on the metabolic changes of multiple systems in CD patients, the application of metabonomics in CD diagnosis and treatment, and the research progress of clinical nutrition intervention.
ABSTRACT
OBJECTIVES@#This study aimed to assess the influence of different types of rapid maxillary expansion on root resorption (RR).@*METHODS@#Literature searches were carried out electronically in five English and two Chinese databases. Randomized controlled trials (RCTs), controlled clinical trials (CCTs), cohort studies, and case-control studies were included. The data were extracted by three authors. The risk of bias in the RCTs and nonrandomized studies were assessed in accordance with corresponding scales.@*RESULTS@#Among the 400 articles identified, seven were included for the final analysis. Three studies were graded as high value of evidence, while two and another two studies were graded as moderate value and low value, respectively. According to the available evidence, the tooth-borne maxillary expansion caused more obvious RR of anchorage teeth than the bone-borne one. In addition, the Haas-type palatal acrylic pads could not effectively reduce the degree of RR. The difference in the design of the retainer between the tooth-borne maxillary expansion (the use of a band or wire framework to connect the anchorage tooth) did not cause the difference in the incidence and degree of RR.@*CONCLUSIONS@#Clinical evidence suggested that bone-borne maxillary expansion may decrease the amount of RR, while the amounts of resorption did not significantly differ between Haas and Hyrax and between different retainer types of Hyrax.

Objective:To solve the problem of leg shaking caused by the sudden change of angular acceleration at the joint of periodic motion during circular gait training of lower limb rehabilitation robot. Methods:A kind of quasi-circular gait was proposed, which divided the periodic motion into three phases: start phase, middle phase and end phase. The time was equal in the start phase and the end phase, and could be adjusted with the parameter ratio. The joint trajectories of the two phases were planned by quintic polynomial, and the middle phase was still the circular gait joint trajectory. The trajectory of the proposed quasi-circular gait was simulated. Results:The angular velocity was continuously differentiable and 0, the angular acceleration was continuous and 0, and the end-effector trajectory became flat with the increase of ratio. The results on the physical prototype of the lower limb rehabilitation robot were principally consistent with the simulation, and the machine worked smoothly. Conclusion:The proposed variable quasi-circular gait had smooth angular acceleration at the junction of periodic motions, which effectively solved the jitter problem when using circular gait for lower limb rehabilitation training and avoided secondary injury to the patients.

ABSTRACT
A device to produce low temperature plasma ( LTP) was designed and constructed to serve as the ion source of a high resolution mass spectrometry, and was applied to qualitatively analyze the steroid samples. In comparison with conventional electrospray ionization mass spectrometry, low temperature plasma mass spectrometry ( LTP-MS) had some advantages such as simple sample pretreatment and less interference. Mass spectrometry and tandem mass spectrometry were used to characterize the steroid samples in this research, and it was found that the structural stability of each steroid sample was presented in its mass spectrum, while in the tandem mass spectra there were more fragments of H2 O lost. And then the fragmentation process of typical steroid samples in collision induced dissociation ( CID ) was discussed based on theoretical calculation. In addition, by comparing tandem mass spectrometry and the fragmentation process, a pair of isomers of testosterone and dehydroepiandrosterone could be distinguished successfully.

ABSTRACT
ObjectiveTo evaluate the consistency of color Doppler ultrasonography (CDFI) and digital subtraction angiography (DSA) in diagnosis of carotid artery stenosis or occlusion. MethodsThe agreement and disagreement between CDFI and DSA examination results in 215 cases with unilateral carotid artery stenosis or occlusion were studied. By reviewing the CDFI sonogram and DSA dynamic image, the reason of discrepancy between two imaging modalities was analyzed.ResultsThe agreement rate was 90.7% (195 cases) between first CDFI scan and DSA, while disagreement rate was 9.3%(20 cases). Thus CDFI and DSA showed a good consistency (Kappa=0.7731,P<0.01). After reviewing the CDFI sonogram and DSA dynamic image, the discrepancy was attributed to treatment response in10 cases (4.7%), imaging principle difference in 3 cases (1.4%) , and inconsistent physician diagnoses in 7 cases (3.2%). ConclusionIn diagnosis of extracranial carotid artery stenosis or occlusion, the results of CDFI and DSA were highly consistent . In inconsistent cases, the examination results should be viewed under comprehensive and complementary analysis.

ABSTRACT
To study the protective effect of Arctigenin in goto-kakizaki (GK) rats combined with hypertension macroangiopathy. Six-week-old GK rats were divided randomly according to blood glucose level into four groups: the model group and low, middle and high dose arctigenin groups (12.5, 25, 50 mg x kg(-1)), with Wistar rats as the normal group. All of GK rats were given high-glucose and high-fat diet. After 16 weeks, GK rats were orally administrated with 10 mg x kg(-1) x d(-1) N-Ω-nitro-L-arginine methyl ester for eight weeks. During the modeling, all of arctigenin groups were orally administrated with different dose of arctigenin twice a day; The model group and the normal group were given solvents. At the beginning, mid-term and end of the experiment, blood glucose was measured. At the end of the experiment, efforts were made to detect blood pressure, collect abdominal aortic blood after anesthesia, fix thoracic aorta after bloodletting to make paraffin sections, observe morphological characteristics and detect the expression of VEGF by immunohistochemistry. According to the results, the blood glucose rose in all GK rats, with no significant difference between the drug group and the model group. At the end of the experiment, the blood pressure significantly increased in GK rats, indicating that Arctigenin could notably reduce the blood pressure in GK rats in a dose-dependent manner. The blood routine test showed increases in both the total white blood cell count and differential blood count, MPV and PDW, abnormal blood platelet parameters and decrease in PLT in GK rats, suggesting that Arctigenin could remarkably reduce the total white blood cell count and differential blood count, MPV and PDW. The thoracic aortic morphological observation revealed obvious endangium lesions in GK rats, demonstrating that Arctigenin could ameliorate the lesion extent. VEGF immumohistochemical staining showed a higher VEGF expression in the model group but lower expression in Arctigenin groups. In conclusion, Arctigenin had a protective effect on aorta in GK rats. Its mechanism may be related to blood pressure lowering, anti-inflammation, improvement in blood platelet function and reduction of VEGF expression.

To compare the curative effects of two surgical treatment methods for open angle glaucoma and cataract patients. ●METHODS: Totally 69 patients with primary open angle glaucoma and cataract were divided into two groups:group A and group B. Thirty- four patients (34 eyes) in group A underwent small incision non -phacoemulsification cataract surgery combined with trabeculectomy, just combined operations, 35 patients (35 eyes) in group B underwent small incision non -phacoemulsification cataract surgery beyond 6mo after trabeculectomy, just two stage operations. Postoperative intraocular pressure at 1wk and 3mo, postoperative corrected visual acuity and filtering bleb at 3mo were observed, and intraoperative and postoperative complications were compared. All the patients were followed up for 3-6mo. ● RESULTS: All the visual acuity were increased compared with that before surgery in two groups, the difference was not statistically significant. All the intraocular pressure was controlled in two groups, the difference was not statistically significant, and the difference about the filtering bleb was neither statistically significant ( P > 0. 05 ). There were no serious intraoperative and postoperative complications in two groups. ● CONCLUSlON: The two stage operations and the combined operations both can control theintraocular pressure and improved visual acuity of open angle glaucoma and cataract. The two stage operations may prevent a second operation for post trabeculectomy cataract, allowing earlier visual rehabilitation.
