ABSTRACT

AIM: To quantify early changes of macular capillary parameters in type 2 diabetic patients using optical coherence tomography angiography(OCTA).METHODS: Retrospective case study. A total of 49 healthy subjects, 52 diabetic patients without retinopathy(noDR)patients, and 43 mild nonproliferative diabetic retinopathy(mNPDR)patients were recruited. Capillary perfusion density, vessel length density(VLD), and average vessel diameter(AVD)were calculated from macular OCTA images(3 mm×3 mm)of the superficial capillary plexus after segmenting large vessels and the deep capillary plexus. Parameters were compared among control subjects, noDR, and mNPDR patients. The area under the receiver operating characteristic curve estimated the abilities of these parameters to detect early changes of retinal microvascular networks.RESULTS: Significant differences were found in the VLD and AVD among the three groups(P<0.001). Compared with the control group, the noDR group had significantly higher AVD(P<0.05). VLD of both layers in patients of mNPDR group was significant decreased compared with that of noDR group(all P<0.01). Deep AVD had a higher area under the curve(AUC)of 0.796 than other parameters to discriminate the noDR group from the healthy group. Deep AVD had the highest AUC of 0.920, followed by that of the deep VLD(AUC=0.899)to discriminate the mNPDR group from the healthy group.CONCLUSIONS: NoDR patients had wider AVD than healthy individuals and longer VLD than mNPDR patients in both layers. When compared with healthy individuals, deep AVD had a stronger ability than other parameters to detect early retinal capillary impairments in noDR patients.

ABSTRACT

Objective:To explore the expression and importance of Piezo1, E-cadherin, and Vimentin in nasal polyps patients. Methods:Thirty-five patients undergoing endoscopic sinus surgery under general anesthesia were streamed into 20 cases of nasal polyps(NP group) and 15 cases of simple septoplasty without any sinus disease(Control group). Immunofluorescence staining and Western Blot were applied to detect the protein level of Piezo1, E-cadherin, and Vimentin in NP tissues and nasal polyp-derived primary human nasal epithelial cells(pHNECs). Also, BEAS-2B cell lines were treated with human TGF-β1 protein to establish epithelial mesenchymal transition(EMT) model in vitro and quantitative real-time polymerase chain reaction were used to calculate Piezo1 and above biomarkers in the model. Results:Compared with control group, Piezo1 and Vimentin showed higher level while E-cadherin was lower in NP tissues and pHNECs.In EMT model in vitro, Piezo1 and Vimentin were demonstrated higher expression with decreased level of E-cadherin. Conclusion:The tendency of Piezo1 is consistent with the mesenchymal-related biomarker Vimentin, going against with epithelial-related biomarker E-cadherin, implying its involvement with EMT process in nasal polyps.

ABSTRACT

Objective:To summarize the clinical phenotype and genetic characteristics of Poirier-Bienvenu neurodevelopmental syndrome associated with CSNK2B gene variation. Methods:The clinical and genetic data of a child with Poirier-Bienvenu neurodevelopmental syndrome caused by shear variant of CSNK2B gene who was diagnosed in the Department of Neurology, Children′s Hospital Affiliated to Zhengzhou University in March 2022 were collected. Previous relevant literature at home and abroad was reviewed to summarize the clinical characteristics of the disease. Results:The child was a girl aged 13 months, mainly due to "intermittent convulsions for 2 months" for consultation. The clinical manifestations of the girl were normal face, generalized tonic-clonic seizures, low intelligence, language and motor retardation, and there was no abnormality in the long-range video electroencephalography and the head magnetic resonance imaging. No abnormality was found in chromosome karyotype analysis and chromosome coefficient of copy variation analysis. The whole exon gene sequencing test indicated that the child carried de novo heterozygous shear variant of CSNK2B gene c.291+5G>C, which had not been reported in the literature. According to the clinical manifestations and genetic examination results of the child, the diagnosis of Poirier-Bienvenu neurodevelopmental syndrome was clear. The CSNK2B gene of the proband′s parents and the twin sister was wild-type. The application of sodium valproate anti-seizure medication could effectively control the seizures of the child, and by giving rehabilitation function training, the child′s language and gross motor function was improved. Conclusions:The Poirier-Bienvenu neurodevelopmental syndrome is a rare autosomal dominant disorder caused by variants in the CSNK2B gene. The clinical manifestations are infancy-onset seizures, intellectual development disorders, language and motor development disorders, etc, and the video electroencephalogram and skull magnetic resonance are mostly normal. The CSNK2B gene shear variant is the genetic etiology of the proband.

ABSTRACT

Objective: A subset of intractable allergic rhinitis (iAR) patients experience severe symptoms which cannot be effectively controlled by standard drug therapy and/or antigen specific immunotherapy. In recent decades, endoscopy vidian neurectomy and posterior nasal nerve neurectomy (PNNN) were introduced as treatments of iAR that have shown to be highly successful at symptom management in a number of patients. But some patients experience relapse or suboptimal symptom control postoperation. To improve the effectiveness of PNNN to control iAR, a modified PNNN surgical approach (mPNNN) combined with accessory posterior nasal nerve neurectomy (aPNNN), which called as mPNNN-aPNNN was used. This study aims to compare the effects between mPNNN-aPNNN and PNNN on controlling the symptoms of iAR and evaluate the surgical effectiveness and safety of mPNNN-aPNNN. Methods: The patients with iAR experienced mPNNN-aPNNN or PNNN surgery at the department of Otolaryngology Head and Neck Surgery of the Second Xiangya Hospital, Central South University from January 2018 to December 2019 were analyzed retrospectively. The approach of PNNN, a selective resection of the posterior nasal nerve branches, was modified to the neurectomy of total branches of posterior nasal nerve at the sphenopalatine foramen, and combined the operation of aPNNN in which the accessory posterior nasal nerve at the palatine bone perpendicular plate was resect in our study. Daily Nasal Symptom Scores (DNSS), Total Rhinitis Medication Score (TRMS), and the Rhinoconjunctivitis Qualities of Life Questionnaires Scores (RQLQS) were used to evaluate the complications during the operation and after the operation at the 3rd, 6th, 12th, and 24th month postoperatively. Total Nasal Symptom Scores (TNSS) was used to assess the total effective rate and markedly effective rate of the operations. Results: A total of 140 iAR patients experienced mPNNN-aPNNN or PNNN. Those with concomitant septoplasty and/or inferior turbinate reduction, and were absent during the postoperative follow-up were excluded. The final 62 patients with mPNNN-aPNNN and 34 with PNNN were enrolled. DNSS, TNSS, TRMS, and RQLQS at the postoperation were significantly improved compared with the preoperation in all patients (all P<0.001). Compared with PNNN, the postoperative DNSS, TNSS, and TRMS of mPNNN-aPNNN were obviously improved (all P<0.001). There was a persisted relief of symptoms at the postoperation in all patients with mPNNN-aPNNN. The total effective rate and markedly effective rate at the postoperative 24th month were 100% and 83.3%, respectively. Furthermore, the postoperative RQLQS decreased significantly (P<0.001). Only 5 sides of all patients (5/192, 2.6%) reported upper palate numbness during the first week after operation, with all recovered spontaneously in 1 month without treatment. No other postoperative complications occurred in mPNNN-aPNNN and PNNN.Conclusion: The surgery of mPNNN-aPNNN improve TNSS more significantly than PNNN. The operation of mPNNN-aPNNN is safe and effective to control iAR symptoms.

ABSTRACT

Objective: To investigate the feasibility of isolation and culture of human adenoid-derived mesenchymal stem cells (aMSCs) in vitro, and to observe the differentiation of aMSCs into olfactory sensory neurons. Methods: Adenoid tissues surgically removed from children with adenoid hypertrophy in the Second Xiangya Hospital of Central South University from September to November of 2020 were collected. The adenoid tissues were digested and isolated by trypsin and then cultured with adhesion method. The expressions of cell surface antigens CD45, CD73 and CD90 on aMSCs of P5 generation were tested by flow cytometry, and the ability of osteogenic and adipogenic induction were used to identify cell differentiation ability. Then, aMSCs were induced into differentiation by retinoic acid (RA), sonic hedgehog (SHH), basic fibroblast growth factor (bFGF), RA+SHH, RA+bFGF, SHH+bFGF and RA+SHH+bFGF, respectively. The morphology of differentiated cells was observed under inverted microscope. The expression of β-tubulin 3, which was the specific marker of sensory neuron, the expressions of growth associated protein-43 (GAP43) and olfactory maker protein (OMP), which were the specific markers of olfactory sensory neuron, were detected by immunofluorescence antibody assay. The expression intensities were compared by Chi-square test of four-grid table data. Results: aMSCs were successively isolated and cultured from human adenoid tissues. P0 cells generation had good adhesion and proliferation performance. P2 cells were basically purified. P5 cells expressed CD73 and CD90 with the purity of 99.3% and 99.75% respectively, without CD45 expression. P5 cells had a good ability of osteogenic differentiation and adipogenic differentiation. Neuron-like morphology and expression of β-tubulin 3 were found in differentiated cells after induced by RA, SHH, or bFGF, respectively. An induction of expression of GAP43 was found in differentiated cells of bFGF+SHH group and RA+SHH+bFGF group, without expression of OMP of each group. The intensity of GAP43 expression of RA+SHH+bFGF group was stronger than that of bFGF+SHH group (χ2=17.48, P<0.005). Conclusions: aMSCs can be cultured from human adenoid tissues, with the stably passaged and good differentiation ability. As a new population of mesenchymal stem cells, aMSCs have the neuroregenerative properties and could differentiate into immature olfactory sensory neurons under the induction of RA+SHH+bFGF in vitro.

ABSTRACT

Hepatocellular carcinoma (HCC) has emerged as a significant public health concern, posing a serious threat to the lives and health of residents in China. Furthermore, the incidence and mortality rates of HCC are notably higher in males than in females. Androgen receptors (AR) can contribute to the occurrence of male-specific cancers such as prostate cancer, suggesting a potential link to the increased susceptibility of males to HCC. Elucidating the cancer-promoting mechanism of AR and developing specific targeted interventions are effective ways to advance tertiary prevention of HCC and improve patient prognosis. This paper reviews the relevant evidence of AR’s role in promoting the occurrence and development of HCC, summarizes relevant mechanisms discovered to date, including promoting the stemness of HCC cells, altering the immune microenvironment, regulating key signaling pathways, inducing glycolysis in hepatocellular carcinoma, and synergizing with hepatitis B virus to promote HCC. Additionally, research directions for targeted interventions in HCC through AR-related signaling pathways are discussed.

ABSTRACT

Endemic fluorosis is a common biogeochemical disease. Although the etiology is clear, its molecular mechanism is not fully understood. So far, there is no specific method to effectively treat fluorosis, mainly to prevent. In recent years, a large number of studies have confirmed that a variety of macro elements such as calcium, magnesium, phosphorus, and trace elements such as selenium and boron play a positive regulatory role in the occurrence and development of fluorosis, and have different degrees of influence in the body's antagonism against fluorosis. High levels of trace elements such as arsenic, lead, aluminum and chromium are risk factors for fluorosis. In view of the importance of a variety of macro and trace elements in human nutrition and health, this article reviews the latest developments in multiple elements and fluorosis, especially skeletal fluorosis and dental fluorosis, in order to further understand the causes of fluoride-induced health damage, and provide theoretical reference for improving the prevention strategies of fluorosis in a targeted manner.

ABSTRACT

Objective To observe the effect of edaravone on endogenous neural stem cells in rats with permanent cerebral ischemia. Methods The rat model of permanent cerebral ischemia was established by electrocoagulation. Thirty SD rats were randomly divided into three groups; sham operation group, brain injury group and edaravone group. Six hours after the establishment of the model, the edaravone group was intraperitoneally injected with 1.5 g/L edaravone (10 ml/kg) once a day. The sham operation group and the cerebral ischemia group were intraperitoneally injected with saline of equal volume for 7 days. 24 hours after the last administration, BrdU positive cells, Nestin/BrdU positive cells, neuronal class III β-tubulin (Tuj1)/BrdU positive cells and glial fibrillary acidic protein (GFAP)/BrdU positive cells were observed by immunofluorescent staining, Tuj1 and GFAP protein expressions were detected by Western blotting. Results Compared with the cerebral ischemia group, the BrdU positive cells, Nestin/BrdU positive cells, Tuj1/BrdU positive cells and GFAP/BrdU positive cells increased significantly in the infraventricular area and the cortex area around the ischemia in the edaravone group (P<0.05). Compared with the cerebral ischemia group, the expression of Tuj1 and GFAP protein in the cerebral cortex of edaravone group increased ( P<0.05). Conclusion Edaravone can promote the proliferation of endogenous neural stem cells and astrocytes in the subventricular area and the cortex around ischemia, and promote the differentiation of endogenous neural stem cells into neurons.

ABSTRACT

OBJECTIVES@#This study aimed to evaluate the color stability of tetracycline teeth restored with ceramic veneers of different thicknesses combined with different resin cement systems after aging.@*METHODS@#Twenty patients with tetracycline teeth, including two maxillary central incisors, were selected clinically. The patients were randomly divided into four groups and restored with 0.5 and 0.75 mm ceramic veneers by using a veneer adhesive system, either with light-cured or dual-cured reaction. The color difference (ΔE) values after cementation and 1, 6, 12, and 24 months of use were obtained by quantification of L*, a*, and b* values with a colorimeter. The results were analyzed statistically with two-way ANOVA and Student's @*RESULTS@#The ΔE values of ceramic veneers detected after aging were less than 2.25. The 0.5 mm groups exhibited greater color change than the 0.75 mm-thick veneers (@*CONCLUSIONS@#Resin cements and veneer thickness influence the color of ceramic veneers after aging. Cementation of veneers with either dual- or light-cured resin cements does not affect the long-term color stability of tetracycline teeth differently.

ABSTRACT

Since the outbreak of 2019-nCoV, the epidemic has developed rapidly and the situation is grim. LANCET figured out that the 2019-nCoV is closely related to "cytokine storm". "Cytokine storm" is an excessive immune response of the body to external stimuli such as viruses and bacteria. As the virus attacking the body, it stimulates the secretion of a large number of inflammatory factors: interleukin(IL), interferon(IFN), C-X-C motif chemokine(CXCL) and so on, which lead to cytokine cascade reaction. With the exudation of inflammatory factors, cytokines increase abnormally in tissues and organs, interfering with the immune system, causing excessive immune response of the body, resulting in diffuse damage of lung cells, pulmonary fibrosis, and multiple organ damage, even death. Arachidonic acid(AA) metabolic pathway is principally used to synthesize inflammatory cytokines, such as monocyte chemotactic protein 1(MCP-1), tumor necrosis factor(TNF), IL, IFN, etc., which is closely related to the occurrence, development and regression of inflammation. Therefore, the inhibition of AA metabolism pathway is benefit for inhibiting the release of inflammatory factors in the body and alleviating the "cytokine storm". Based on the pharmacophore models of the targets on AA metabolic pathway, the traditional Chinese medicine database 2009(TCMD 2009) was screened. The potential herbs were ranked by the number of hit molecules, which were scored by pharmacophore fit value. In the end, we obtained the potential active prescriptions on "cytokine storm" according to the potential herbs in the "National novel coronavirus pneumonia diagnosis and treatment plan(trial version sixth)". The results showed that the hit components with the inhibitory effect on AA were magnolignan Ⅰ, lonicerin and physcion-8-O-β-D-glucopy-ranoside, which mostly extracted from Magnoliae Officinalis Cortex, Zingiberis Rhizoma Recens, Lonicerae Japonicae Flos, Rhei Radix et Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma, Scutellariae Radix, Gardeniae Fructus, Ginseng Radix et Rhizoma, Arctii Fructus, Dryopteridis Crassirhizomatis Rhizoma, Paeoniaeradix Rubra, Dioscoreae Rhizoma. Finally the anti-2019-nCoV prescriptions were analyzed to obtain the potential active prescriptions on AA metabolic pathway, Huoxiang Zhengqi Capsules, Jinhua Qinggan Granules, Lianhua Qingwen Capsules, Qingfei Paidu Decoction, Xuebijing Injection, Reduning Injection and Tanreqing Injection were found that may prevent 2019-nCoV via regulate cytokines. This study intends to provide reference for clinical use of traditional Chinese medicine to resist new coronavirus.

ABSTRACT

Liver injury caused by acetaminophen (AP) overdose is a leading public health problem. Although AP-induced liver injury is well recognized as the formation of N-acetyl-p-benzoquinone (NAPQI), a toxic metabolite of AP, resulting in cell damage, emerging evidence indicates that AP-induced liver injury is also associated with gut microbiota. However, the gut microbiota-involved mechanism remains largely unknown. In our study, we found that vancomycin (Vac) pretreatment (100 mg/kg, twice a day for 4 days) attenuated AP-induced liver injury, altered the composition of gut microbiota, and changed serum metabolic profile. Moreover, we identified Vac pretreatment elevated cecum and serum 2-hydroxybutyric acid (2-HB), which ameliorated AP-induced cell damage and liver injury in mice by reducing AP bioavailability and elevating GSH levels. Our current results revealed the novel role of 2-HB in protecting AP-induced liver injury and add new evidence for gut microbiota in affecting AP toxicity.

ABSTRACT

OBJECTIVE@#To evaluate the effects of different postoperative analgesic strategies on neurocognitive function and quality of recovery in elderly patients at 7 days after thoracic surgery with one lung ventilation.@*METHODS@#Ninety elderly patients undergoing video-assisted thoracic surgery were randomized into 3 groups (@*RESULTS@#The patients in TA and EA groups had significantly higher MMSE scores and lower incidence of postoperative neurocognitive dysfunction (PNCD) than those in GA group without significant difference between the former two groups. At 7 days after the surgery, serum levels of S100-β and MMP-9 were significantly higher in GA group than in TA and EA group, and did not differ significantly between the latter two groups. QoR-40 scores were significantly higher in TA and EA groups than in GA group, and were higher in TA group than in EA group. The chest intubation time and length of hospital stay were significantly shorter in TA and EA groups than in GA group.@*CONCLUSIONS@#In elderly patients undergoing surgeries with one lung ventilation, general anesthesia combined with either postoperative continuous thoracic paravertebral block or epidural analgesia can significantly improve postoperative neurocognitive function and quality of recovery, but continuous thoracic paravertebral block analgesia can be more advantageous for improving postoperative quality of recovery.

ABSTRACT

BACKGROUND@#The proportion of recurrences after discharge among patients with coronavirus disease 2019 (COVID-19) was reported to be between 9.1% and 31.0%. Little is known about this issue, however, so we performed a meta-analysis to summarize the demographical, clinical, and laboratorial characteristics of non-recurrence and recurrence groups.@*METHODS@#Comprehensive searches were conducted using eight electronic databases. Data regarding the demographic, clinical, and laboratorial characteristics of both recurrence and non-recurrence groups were extracted, and quantitative and qualitative analyses were conducted.@*RESULTS@#Ten studies involving 2071 COVID-19 cases were included in this analysis. The proportion of recurrence cases involving patients with COVID-19 was 17.65% (between 12.38% and 25.16%) while older patients were more likely to experience recurrence (weighted mean difference (WMD)=1.67, range between 0.08 and 3.26). The time from discharge to recurrence was 13.38 d (between 12.08 and 14.69 d). Patients were categorized as having moderate severity (odds ratio (OR)=2.69, range between 1.30 and 5.58), while those with clinical symptoms including cough (OR=5.52, range between 3.18 and 9.60), sputum production (OR=5.10, range between 2.60 and 9.97), headache (OR=3.57, range between 1.36 and 9.35), and dizziness (OR=3.17, range between 1.12 and 8.96) were more likely to be associated with recurrence. Patients presenting with bilateral pulmonary infiltration and decreased leucocyte, platelet, and CD4@*CONCLUSIONS@#The main factors associated with the recurrence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) after hospital discharge were older age, moderate severity, bilateral pulmonary infiltration, laboratory findings including decreased leucocytes, platelets, and CD4

ABSTRACT

ObjectiveSurgical site infection (SSI)is a type of common hospital-acquired wounds. The purpose of this study is to understand its clinical characteristics and prognosis in order to provide evidence for taking appropriate measures.Methods132 wound patients who met the diagnostic criteria of surgical site infection in the wound care center in recent 3 years were enrolled. The patients were treated locally with nanosilver dressing combined with red light and infrared ray. Individualized nutritional recipes and activity prescriptions were given, and the skin was showered every other day to heal or last 2 months.Observation indicators: demographics and wound characteristics; changes of area and depth after14 days intervention; the posi-tive rate of bacteria before and after the intervention, and healing rate and healing time of 2 months were analyzed and compared.ResultsA total of 132 cases of SSI(52.27% superficial and 47.73% deep ) was identified. The average age was 48.33±16.90 years. The average age and gender of the two groups were similar (P>0.05).Peri-wound skin is contaminated in all cases. The mean onset time of SSIs was 19.82±5.64 days, and the median onset time was 20 days. The onset time and duration of deep SSIs were longer than that of superficial SSIs (P0.05), and the depth of deep SSIs was deeper than that of superficial SSIs (P<0.05).The positive rate of bacterial culture inthe deep SSI group (79.31%) was higher than that of the superficial SSI group (59.46%) (P<0.05). After 14 days treatment, the area was smaller, the depth was lower (P<0.05), and the positive rate of bacteria was significantly decreased in the two groups (P<0.05). The healing rate ofsuperficial SSI group (84.06%) was higher than that of deep SSI group (66.67%) (P<0.05) in two months, and the healing time of superficial SSI group was significantly shortened (35.46<11.12 days vs 41.08<11.33 days, P<0.05). Logistic regression analysis showed that negative bacterial culture before intervention increased the healing index (OR=0.190). Long-term use of antibiotics did not promote healing (OR=0.343).ConclusionSuperficial and deep SSIs are common types of SSIs. Gender and age are similar, and skin contamination may play a role in the development of SSI,which needs attention. Local and systemic interventions can effectively improve wound healing. Negative bacterial culture and proper use of antibiotics can improve the healingprobability.
