Abstract
Diabetic foot is one of the serious complications of diabetic patients, which makes the society and public health bear a huge economic burden. In recent years, more and more studies at home and abroad have been conducted on the treatment of chronic wounds with autologous platelet-rich fibrin, and the therapeutic concepts and methods have been updated constantly. In this paper, we reviewed the general situation of autologous platelet-rich fibrin, the mechanism of autologous platelet-rich fibrin in promoting the healing of diabetic foot ulcers and the new progress in its application, so as to provide a new strategy for the repair of diabetic foot ulcers.

Abstract
Objective: To investigate the trend of postoperative cavity status in patients with eosinophilic chronic sinusitis with nasal polyps (eCRSwNP) who underwent total nasalization surgery and partial reboot surgery. And to discuss the relationship between tissue eosinophil counts and status of postoperative cavity. Methods: Patients with eCRSwNP in four tertiary medical centers (Longgang ENT Hospital, Xiamen Humanity Hospital, Guangdong Clifford Hospital and the First Affiliated Hospital of Sun Yat-Sen University) from March 2018 to October 2021 were divided into 2 groups. The group without previous surgery history was performed for the nasalization surgery, and another group with previous surgery history underwent the part-reboot surgery. The follow-up time after operation was defined as the following 5 stages: 6, 12, 20-24, 36 and more than 42 months. According to FESS-95 Guangzhou standard, status of sinus cavity was assessed and classified into 3 categories: good, better and bad. The association between the sinus cavity status and tissue eosinophil counts in the above 5 stages was analyzed by one-way ANOVA, and P<0.05 was considered statistically significant. Results: A total of 72 eCRSwNP patients finished the follow-up in this study. There were 47 males and 25 females in these patients, aged from 11 to 67 years. A total of 50 cases underwent nasalization surgery and 22 cases underwent partial reboot surgery. With the follow-up time from 6 to 48 months, there were 72 cases (100.0%) who completed 6 months and 12 months follow up, 46 cases (63.9%) for 20-24 months, 36 cases (50.0%) for 32-36 months and 16 cases (22.2%) with the follow-up time more than 42 months. No matter what kind of surgery, there was no "bad" situation of the surgical cavity status 6 months after the operation, and the differentiation gradually occurred more than 12 months after the surgery. Moreover, the rates of "good" cavity status for the 5 stages in the group of nasalization surgery were 78.0%, 66.0%, 56.7%, 47.6% and 42.9%, and were 63.6%, 45.5%, 25.0%, 20.0% and 11.1% in the partial reboot surgery group, respectively, suggesting that the status of nasal cavity in nasalization surgery group was always better than that in partial reboot surgery group in every period. In addition, the "bad" rate was 0, 8.0%, 10.0%, 14.3% and 28.6% in the group of nasalization surgery, and was 0, 27.3%, 18.8%, 33.3% and 55.6% in the partial reboot surgery group, respectively. The average percentage of tissue eosinophil counts in the 72 cases was 42.1%, which had no obvious effect on the status of the surgical cavity (P>0.05). Conclusions: For eCRSwNP patients, the operative cavity status in the patients without previous operation history treated with nasalization surgery is good. The time of 1-2 years after surgery is the main period for sinus lesions. The counts of tissue eosinophils has no significant influence on surgical sinus cavity status in the eCRSwNP patients.

Abstract
Obesity is a leading global health problem contributing to various chronic diseases, including type II diabetes mellitus (T2DM). The aim of this study was to investigate whether blueberries, yoghurt, and their respective bioactive components, Cyanidin-3-O-β-glucoside (C3G) and peptides alone or in combinations, alter the expression of genes related to glucose metabolism in skeletal muscles from diet-induced obese mice. In extensor digitorum longus (EDL), yoghurt up-regulated the expression of activation of 5’adenosine monophosphate-activated protein kinase (AMPK), insulin receptor substrate-1 (IRS-1), phosphatidylinositol-3 kinase (PI3K) and glucose transporter 4 (GLUT4), and down-regulated the expression of angiotensin II receptor type 1 (AGTR-1). The combination of blueberries and yoghurt down-regulated the mRNA expression of AGTR-1 and Forkhead box protein O1 (FoxO1) in the EDL. Whereas the combination of C3G and peptides down-regulated AGTR-1 and up-regulated GLUT4 mRNA expression in the EDL. In the soleus, blueberries and yoghurt alone, and their combination down-regulated AGTR-1 and up-regulated GLUT4 mRNA expression. In summary blueberries and yoghurt, regulated multiple genes associated with glucose metabolism in skeletal muscles, and therefore may play a role in the management and prevention of T2DM.

Abstract
PURPOSE Ghrelin, a gastric hormone, provides a hunger signal to the central nervous system to stimulate food intake. Ghrelin also modulates neuroinflammatory and apoptotic processes. Dedicator of cytokinesis 4 (DOCK4), a guanine nucleotide exchange factor (GEF), is involved in the regulation of neuronal polarization and axon regeneration. However, the effect of DOCK4 on ghrelin production has not been explored. METHODS The expression of DOCK4 in human and mouse stomach was examined by immunohistochemical staining. The synthesis and secretion of ghrelin in Dock4 null mice were evaluated by real-time quantitative PCR, Western blot and ELISA. The effects of DOCK4 on ghrelin production in mHypoE-42 cells were measured by real-time quantitative PCR and Western blot. RESULTS We showed that DOCK4 was expressed in both human and mouse gastric ghrelin cells. The mRNA and protein levels of gastric ghrelin, as well as ghrelin secretion, were remarkably diminished in Dock4 null mice. Furthermore, we showed that overexpression of Dock4 significantly stimulated ghrelin expression, while siRNA knockdown of endogenous Dock4 resulted in a marked decrease of ghrelin in mHypoE-N42 cells. CONCLUSIONS Our results identify DOCK4 as a critical regulator for ghrelin production in gastric X/A-like cells.

Abstract
PURPOSE Caloric restriction (CR) and Roux-en-Y Gastric Bypass (RYGB) are considered effective means of body weight control, but the mechanism by which CR and RYGB protect against high-fat diet (HFD)-induced obesity remains elusive. The browning of white adipose tissue (WAT) is a potential approach to combat obesity. Here we assess whether browning of WAT is involved in CR- and RYGB-treatment. METHODS The average size of adipocytes was determined by histological analysis. Expression of thermogenic genes in both human subjects and mice were measured by quantitative real-time PCR and immunohistochemical staining. RESULTS The average size of adipocytes was bigger, while the expression of thermogenic genes such as uncoupling protein 1 (UCP1), nuclear factor erythroid-2 like 1 (NRF1) and PPARγ coactivator-1 α (PGC1α) were lower in the WAT of obese subjects when compared to lean controls. Both CR and RYGB promoted weight and fat loss. Increment of the average adipocytes size and down-regulation of thermogenic genes were significantly reversed by both CR and RYGB in the WAT of obese mice. CONCLUSIONS Our findings showed that CR and RYGB significantly improved high-fat diet-induced lipid accumulation by promoting the browning of WAT.

Abstract
Abstract
Introduction/Objective
Genes involved in histone methylation are frequently mutated in non-Hodgkin’s lymphomas. For instance, frequent mutations in genes encoding histone methytransferases MML2 and EZH2 are present in diffuse large B cell lymphoma (DLBCL) and follicular lymphoma (FL). The aim of this study was to characterize the immunohistochemical expression of H3K4Me3 in benign/reactive lymph nodes (LNs) with comparison to follicular lymphoma (FL).
Methods/Case Report
Immunohistochemical staining with an anti-H3K4Me3 antibody was performed on FFPE whole slide section from patients with benign/reactive LNs (n=21), low grade (grade 1-2) FL (n=21). H3K4Me3 reactivity was scored for staining intensity and percentage of lymphocytes showing reactivity.
Results (if a Case Study enter NA)
The majority of the reactive LN sections (15 out of 21 cases) showed a distinct distribution of H3K4Me3 staining, with the majority of cells in the mantle zone and the interfollicular zones showing moderate-strong staining, whereas reactive germinal centers (GCs) showed significantly decreased or close to negative staining. Neoplastic follicles in all the FL cases contained positive cells with significantly stronger staining compared to that in the germinal centers in benign lymph nodes. The interfollicular zones, while diminished in FL due to expanded neoplastic follicles, showed retained H3K4Me3 staining. The difference in staining intensity between follicles and mantle/interfollicular zones became indistinct in FL.
Conclusion
H3K4Me3 expression in benign/reactive LNs is characterized by positive expression in lymphocytes in interfollicular and mantle zones and significantly decreased in GCs. However, the expression pattern is different in FL, which showed significantly increased expression in the follicles compared to that in reactive GCs. In FL, the expression in GCs is similar to that in the interfollicular and mantle zone lymphocytes. It is reported that about 90% of FL have MLL2 mutation and MLL2 is the enzyme responsible for the methylation of H3K4. So far, it is unclear whether the mutation of MLL2 in FL affects the overall methylation activity of the enzyme. In our study, there is increased methylation of H3K4 in the follicles of FL, which raises the possibility that MLL2 mutation somehow increases H3K4 methylation.

Abstract
We report ^{51}V NMR and inelastic neutron scattering (INS) measurements on a quasi-1D antiferromagnet BaCo_{2}V_{2}O_{8} under transverse field along the [010] direction. The scaling behavior of the spin-lattice relaxation rate above the Néel temperatures unveils a 1D quantum critical point (QCP) at H_{c}^{1D}≈4.7 T, which is masked by the 3D magnetic order. With the aid of accurate analytical analysis and numerical calculations, we show that the zone center INS spectrum at H_{c}^{1D} is precisely described by the pattern of the 1D quantum Ising model in a magnetic field, a class of universality described in terms of the exceptional E_{8} Lie algebra. These excitations are nondiffusive over a certain field range when the system is away from the 1D QCP. Our results provide an unambiguous experimental realization of the massive E_{8} phase in the compound, and open a new experimental route for exploring the dynamics of quantum integrable systems as well as physics beyond integrability.

Abstract
Many factors still need to be evaluated to fully understand the physical mechanisms determining optical cavity vibration, which are crucial for designing and constructing a transportable ultra-stable laser. Herein, a detailed dynamic analysis is used to characterize the vibration modes of a transportable optical cavity. The first five resonance modes are identified in the presence of a cavity support, and the guidelines to achieve a high first-order resonance frequency are proposed; thereby, high robustness is described using a 50 mm length optical cavity. The results demonstrate that the first-order resonance of up to 681 Hz with a gross weight of 2.51 kg can be achieved using an optimization strategy for given cavity support. The theoretical results are consistent with simulation and experiment. With the optimal group, a 1.34 Hz linewidth transportable ultra-stable laser at 1550 nm is established, and a linewidth of 1.5 Hz and frequency instability of 9.5×10-15@1s are obtained after the test including 100 km actual road transportation and 34 min continuous vibration. The test condition is equivalent to ∼ 1000 km road transportation. Our method can be readily extended to other transportable optical cavities, providing a powerful tool for improving the robustness of vibration, particularly important for transportable environments.

Abstract
Objective: To explore the otological and hearing characteristics in children with Turner syndrome (TS), to determine risk factors of hearing loss, and to discuss algorithms for future surveillance. Methods: The clinical data of otolaryngology in children with TS from January 2018 to April 2020 were reviewed retrospectively. A total of 46 female children with TS, aged from 5 to 18 years were enrolled. Karyotypes included 17 cases (37.0%) of monosomy, 16 cases (34.7%) of mosaicism, and 13 cases (28.3%) of abnormal X chromosome structures. The otoscopic characteristics, audiological performance, and otologic diagnoses were evaluated. Multivariate logistic regression and Mann-Whitney U test were used for statistical analysis. Results: The most common otologic comorbidity was otitis media with effusion (OME), including 20 cases (43.5%) with 33 ears (35.9%). 14 cases (30.4%) were diagnosed with hearing loss. The regression analysis revealed that the age (OR=1.345, 95%CI: 1.072-1.760) and comorbidity of OME (OR=9.460, 95%CI: 2.065-60.350) were risk factors associated with hearing loss. In TS with OME, when compared with the mean air conduction threshold, the hearing loss of the group with pars flaccida retractions was significantly higher ((24.3±13.8) dB HL vs. (14.4±4.2) dB HL, U=59.500, P=0.008) than that of the group with none retractions. Conclusion: OME and hearing loss are common in children with TS. As age increases or suffers from OME, the risk of hearing loss increases.

Abstract
IntroductionDuring an out-of-hours shift, the initial assessment of a CAMHS patient is performed by the paediatric trainee, usually the paediatric SHO (senior-house-officer). During my placement as a paediatric SHO, I was aware of a gap in formalised metal state examination teaching for paediatric juniors, which would be crucial for a thorough assessment of these patients, and to better guarantee they are safely managed until further assessment.ObjectivesThe aim is to provide a short teaching session on mental state examining of the CAMHS patent to paediatric SHOs in order to improve their confidence in assessment.MethodsIn order to assess initial confidence in assessing the mental-state of a CAMHS patient, a pre-teaching questionnaire was given to the paediatric SHOs. A 30-minute teaching session on the mental state exam was then carried out and a post-teaching questionnaire was then given to the same trainees.Results
Paired sample Wilcoxons signed rank test found that training significant improved trainees’ confidence in taking a psychiatric mental state exam (p= 0.005, r = 0.628), and improved their confidence in presenting a mental state exam (p = 0.0041, r = 0.6420).Conclusions
Being able to confidently assess the mental state of a CAMHS patient in an on call shift is important for the initial assessing paediatric trainee. However this is often not taught in the paediatric curriculum and trainees have expressed some anxiety in performing this assessment overnight, before a more comprehensive assessment by a CAMHS professional. A simple teaching session may help to reduce this anxiety and improve trainees’ confidence.

Abstract
Exosomes are a kind of membrane vesicle with a diameter of 30-150 nm. It is formed by the budding of multiple vesicles in cells, which can fuse with the cell membrane and be released into the extracellular matrix. Adipose derived stem cells (ADSCs) have the potential of self-renewal and multi-directional differentiation. They can transport the active substance, regulate the inflammatory response, cell migration, proliferation, differentiation and angiogenesis via the action of paracrine exosomes, so as to enhance the ability of wound repair, promote wound healing, and inhibit the formation of scars. Chronic wounds refer to the wounds that can not reach the anatomic and functional integrity through the normal, orderly, and timely repair process, and the course of the wound healing is more than 4 weeks. At present, there are various treatment methods for chronic wounds, among which ADSCs, although showing a good application prospect, have some limitations due to ethical issues, while exosomes can avoid this problem. This article reviews the treatment of chronic wounds with ADSC exosomes.
