Objective:To analyze the feasibility and clinical efficacy of mirror reconstruction in total hip arthroplasty (THA) assisted by visual treatment solution (VTS) for patients with Crowe type II-III developmental dysplasia of the hip (DDH).Methods:Included in this study were 67 patients (67 hips) with unilateral Crowe type II-III DDH undergoing primary THA from June 2022 to August 2023. According to the reconstruction position of the rotation center, the patients were divided into mirror group and high group. There were 37 patients (37 hips) in the mirror group, reconstructed by referring to the rotation center of contralateral normal hip, with 8 males and 27 females, aged 40.9±16.7 years old and 30 patients (30 hips) in the high group, reconstructed by the "high hip center" strategy, with 7 males and 23 females, aged 38.3±11.1 years old. The radiographic results between the affected hip and the normal hip in 12 months postoperatively and the clinical results before and after the operation were compared.Results:All the operations for patients with Crowe type II-III DDH were completed successfully. The operation time, intraoperative blood loss and the follow-up time in the mirror group were 113.9±22.9 min, 287.8 ±181.6 ml and 12.8±1.8 months, respectively, while those in the high group were 118.0±26.2 min, 293.3±125.8 ml and 13.7±2.3 months respectively without significant difference between the two groups. In 12 months postoperatively the rotation center height, greater trochanter height and femoral offset of 37 hips in the mirror group were 16.1±3.8 mm, 17.7±5.2 mm and 34.4 ±5.1 mm, respectively, which were not significantly different from those of the normal side, while the HHS and WOMAC osteoarthritis index were significantly improved compared to those before operation from 32.3±5.3 and 76.9±5.4 points to 84.3±6.3 and 9.4±2.5 points ( t=-34.222, P<0.001; t=64.486, P<0.001). In the high group, the rotational center height, greater trochanter height and femoral offset of 30 hips were 27.9±3.7 mm, 25.4 ±7.9 mm and 35.4 ±6.2 mm, respectively, which were significantly higher than those in the normal side ( t=-15.706, P<0.001; t=-6.494, P<0.001; t=-2.555, P=0.016), and the HHS and WOMAC osteoarthritis index were significantly improved compared to those before operation from 30.9±4.8 and 78.7±5.3 points to 79.5±4.9 and 13.9±3.3 points ( t=-37.339, P<0.001; t=64.375, P<0.001). The HHS and WOMAC osteoarthritis index in the mirror group significantly improved compared with the high group in 12 months postoperatively ( t=3.404, P=0.001; t=-6.315, P<0.001). The X-ray at last follow-up showed that all prostheses were in a stable position. Conclusion:Compared with the high hip center reconstruction, satisfactory outcomes in terms of functional recovery and radiographic evaluation could be achieved in patients with Crowe type II-III DDH undergoing VTS-assisted THA of mirror reconstruction. The application of mirror reconstruction is expected to achieve the goal of restoring the anatomical structure and function of the primary hip after THA.

Objective To investigate the pollution level of 9,10-anthraquinone in teas sold in Wuhan, and to assess the dietary exposure of 9,10-anthraquinone ingested through tea. Methods The content of 9,10-anthraquinone in teas collected from local tea markets in Wuhan was analyzed by GC-MS/MS. Results 9,10-anthraquinone was detected in all 36 tea samples with a concentration ranging from 0.0080 mg/kg to 0.137 mg/kg. The standard limit for 9,10-anthraquinone has not yet been set in China. Referring to EU standards, the total over-standard rate was 86.11% (31/36). Generally, the concentration of residual 9,10-anthraquinone was higher in highly fermented teas. The highest average concentration of residual 9,10-anthraquinone was found in fully/post-fermented tea (0.0762 mg/kg), and the over-standard rate was 100%. The second highest was in semi-fermented tea (0.0452 mg/kg), and the over-standard rate was 86.7%. The concentration of 9,10-anthraquinone in non-fermented tea was 0.0262 mg/kg, and the over-standard rate was 42.9%. According to people^’s tea-drinking habits, tea samples were brewed with boiling water（1:50）for 5 minutes, and the concentration of 9,10-anthraquinone in tea soup was 0.0004 mg/kg～0.01 mg/kg, with an average leaching rate of 7.2%. The average daily intake exposure of tea for an adult was 0.0551μg/kg bw/day. Conclusion There was a certain degree of 9,10-anthraquinone pollution in the teas sold in Wuhan, and the rate exceeding the standard was high. Since the acceptable daily intake (ADI) for 9,10-anthraquinone has not been established, it is impossible to assess the health risks of 9,10-anthraquinone ingested through tea.

Objective: To explore the expression of amphiregulin (AREG) in nasal polyps patients with different degrees of eosinophil infiltration, and to analyze the correlation between AREG and tissue remodeling. Methods: Forty-eight patients underwent endoscopic sinus surgery in the Department of Otorhinolaryngology Head and Neck Surgery, Remin Hospital, Wuhan University from July 2017 to August 2018 were recruited, including 40 males and 8 females, aged from 16 to 60 years old. The subjects were divided into three groups: control group (n=14), eosinophilic chronic sinusitis with nasal polyps (ECRSwNP) group (n=19) and noneosinophilic chronic rhinosinusitis with nasal polyps (non-ECRSwNP) group (n=15). The relative expression of AREG in nasal mucosa was detected by Western blot assay and immunohistochemical staining. Tissue remodeling was detected by HE staining, AB-PAS staining and Masson staining. Kruskal-Wallis test was used for comparison among multiple groups, and Spearman correlation analysis was conducted between the expression level of AREG and the related indexes of tissue remodeling. Results: The expression of AREG in ECRSwNP group was significantly higher than that in non-ECRSwNP group and control group (median protein expression of Western blot was 1.592 vs 0.617 vs0.582, all P<0.05). The degree of epithelial injury and goblet cell metaplasia in ECRSwNP group was significantly higher than that in control group (all P<0.05), the percentage of collagen fibrosis area in ECRSwNP group was significantly lower than that in control group (P=0.01). In chronic rhinosinusitis with nasal polyps (CRSwNP) patients, the area of mucous glands was negatively correlated with the expression of AREG (r=-0.616, P<0.05), and the percentage of collagen fibrosis area was negatively correlated with the expression of AREG (r=-0.738, P<0.05). Conclusion The expression of AREG is higher in ECRSwNP patients, which is related to the process of tissue remodeling.

Objective: To study the expression and significance of Notch1-Jagged1 in nasal mucosa of allergic rhinitis (AR) mouse model in various stages and in the serum of AR patients. Methods: Thirty-six mice were divided into 3 groups: control group, basal sensitization group (OVA) and OVA/AR group, with 12 mice in each group. Allergic symptom in each group were scored after AR model establishment. HE staining method was used to observe the nasal mucosa eosinophils infiltration. ELISA was used to detect the serum level of total IgE. Flow cytometry was used to detect the change of Treg cells in each group. Western blot was used to detect the expression of Notch1 and Jagged1 in nasal mucosa. Flow cytometric bead array (CBA) was used to detect the level of Th1/Th2/Th17 cytokines in splenic lymphocytes. The serum was obtained from 50 patients with AR and 30 control volunteers in Department of Otorhinolaryngology Head and Neck Surgery, Renmin Hospital of Wuhan University from June to October 2017. ELISA was used to detect the expression of Notch1 and Jagged1. Results: Compared with the control group, the allergy symptom, the number of nasal mucosal eosinophils and the level of total IgE were not significantly different in basal sensitization group, but increased significantly in OVA/AR group (6.11±0.78 vs 0.67±0.50, 77.67±5.61 vs 10.33±0.82, (106.80±11.91) pg/ml vs (82.45±19.80) pg/ml, t value was 19.471, 34.848, 2.542, respectively, all P<0.05). Compared with the control group, the ratio of Treg cell increased in basal sensitization group but decreased in OVA/AR group ((10.29±0.47)% vs (9.28±0.16)%, (8.49±0.15)% vs (9.28±0.16)%, t value was 5.838, 4.540, respectively, all P<0.01). Compared with control group, the expression of Notch1 increased significantly both in basal sensitization group and OVA/AR group (1.04±0.05 vs 0.71±0.05, 1.83±0.10 vs 0.71±0.05, t value was 9.293, 31.363, respectively, all P<0.01); and the expression of Jagged1 only increased significantly in OVA/AR group (0.41±0.04 vs 0.21±0.01, t=13.472, P<0.01). It was found that Notch1 was positively correlated with the level of IL-6, IL-10 by Pearson test (r value was 0.98, 0.87, respectively, all P<0.01). Compared with control volunteers, the expression of Notch1 and Jagged1 increased significantly in AR group patients ((1 135.0±254.9) pg/ml vs (436.0±139.3) pg/ml, (1 200.2±401.0) pg/ml vs (559.9±124.2) pg/ml, t value was 13.99, 11.94, respectively, all P<0.01). Conclusions The expression of Notch1 receptor and ligand increased significantly in the pathogenesis of AR. Notch1-Jagged1 may promote the occurrence and development of AR by up-regulating the expression of IL-6 and IL-10.

PURPOSE: Maternal influences contribute to the origin of allergic diseases, but the mechanisms are not clear. The current literature prompted the role of epigenetics in the development of allergic diseases. We sought to investigate the roles of regulatory T (Treg) cells and Forkhead box p3 (Foxp3) DNA methylation in the process of maternal transmission of allergic rhinitis (AR) susceptibility. METHODS: BALB/c female mice (AR mother) were sensitized by intraperitoneal injection of Dermatophagoides pteronyssinus (Der p) 1 on day 1 and 7. Then they mated with normal male mice on day 8. From day 21 to 28, the female mice were intranasal challenged with Der p 1 continuously. The normal controls were given with normal saline in the same way. On postnatal day 3, Female mice and their offspring were sacrificed to detect their histopathology in nasal mucosae, cytokines in sera of mother and spleen homogenates of offspring, Treg cells count, Foxp3 mRNA expressions, and Foxp3 DNA methylation levels in spleens. RESULTS: Compared with the normal controls, neonatal offspring of Der p 1-stimulated female mice (AR offspring) showed the elevation of interleukin (IL)-4 (P<0.01) and IL-17 (P<0.01), the submission of IL-10 (P<0.01) in spleen homogenates. Further, Treg cells count in AR offspring decreased remarkably compared with the normal offspring (P<0.01). Though the difference of Foxp3 DNA methylation level between AR offspring and normal control offspring was not obvious, correlation analysis demonstrated that there was significantly positive correlation between Foxp3 DNA methylation level of mother and that of offspring (r=0.803, P<0.01). CONCLUSIONS: Under the influence of Maternal AR, their neonatal offspring develop into T-helper type 2 (Th2) dominant immune state, which is closely associated with the recession of Treg cells. Foxp3 DNA methylation may be a mechanism responsible for that maternal effect but still need more studies to ensure.

OBJECTIVE: To evaluate the perioperative analgesic effects of parecoxib sodium in patients undergoing nasal endoscopic surgery. METHOD: In the randomized, double blind, controlled study, 120 patients undergoing septoplasty were divided into 3 groups (n = 40): A group received parecoxib at a dose of 40 mg by muscle injection 30 min before the operation followed by saline at the same volume every 24 h for 48 h; B group received parecoxib at a dose of 40 mg by muscle injection 30 min before the operation followed by 40 mg every 24 h for 48 h; C group received an equal volume of 0.9% saline at the same time points. Patients were assessed with respect to pain score (VAS), rescue analgesia requirement and the side effects during the operation as well as at 3, 24, 48 h after the surgery. RESULT: Intra-operative as well as the postoperative pain scores were less in the A group and B group than in the.control group. Compared with group A, group B had significantly lower VAS score at 24 h after the operation, however there were no significant difference on other time points. Fewer participants of both the A and B groups required rescue medication after operation. CONCLUSION Administration of parecoxib can provide ideal analgesic effects without serious adverse side effects at the perioperative period for patients who received nasal endoscopic operation. Intramuscular parecoxib (40 mg 30 min before the operation followed 40 mg qd for 48 h) designed as preoperative analgesia mode resulted in sufficient perioperative analgesia that deserves popularization in the clinical works.

OBJECTIVE: To evaluate the preemptive analgesia effects of both the parecoxib sodium and the pentazocine in patients undergoing nasal endoscopic surgery. METHOD: In the randomized, double blind, controlled study, 120 patients undergoing septoplasty were divided into 3 groups (n = 40): group A received parecoxib 40 mg by muscle injection 30 min before the operation; group B received pentazocine 30 mg; group C received an equal volume of saline. The preemptive analgesia effect was evaluated with VAS scores which recorded at different time points. The proportion of participants using rescue analgesia after the operation were recorded as additional measures of preemptive analgesia. RESULT: Intra-operative as well as the postoperative pain scores were less in the group A and group B than in the control group. Fewer participants required rescue medication after operation with parecoxib as well as pentazocine than placebo. However there were no difference in the preemptive effects between the group A and group B. CONCLUSION Administration of both the parecoxib and pentazocine before the nasal endoscopic surgery can provide preemptive analgesia without serious adverse side effects that deserves popularization in the clinic.

OBJECTIVE: To summarize the clinical features of epistaxis in the posterior fornix of inferior meatus and its comprehensive treatment measures. METHOD: We collected and retrospectively analyzed the clinical data of 212 cases of epistaxis hospitalized in our department, among which 23 cases were diagnosed as epistaxis in the posterior fornix of inferior meatus. They underwent nasal endoscopic exploration and coagulation surgery with one case under general anesthesia and the other 22 under local anesthesia. The bleeding from olfactory cleft, spheno-ethmoidal recess and the middle nasal meatus were excluded for all the patients during the surgery. After shifting the inferior turbinate inward by fracture, the active bleeding was found in the posterior fornix of inferior meatus, which was stopped immediately by bipolar coagulation. The areas of coagulation and nasal mucosa erosion were packed with nasopore after operation. RESULT: For all the patients, bleeding spots were definitely located during the operation and successfully coagulated. None of them suffered from recurrent-bleeding within 1 week postoperatively. Followed up for 6 to 12 months, there was no epstaxis recurrence or nasal cavity adhesion at the bled side in all patients. CONCLUSION For intractable epistaxis patient, after excluding the bleeding in olfactory cleft, sphenoethmoidal recess and the middle nasal meatus, it should be considered that the bleeding might come from posterior fornix of inferior meatus. It is the key point to thoroughly expose the posterior fornix of inferior meatus by shifting the inferior turbinate inward by fracture and explore for the bleeding spot carefully.

OBJECTIVE: To compare the therapeutic effect of radiofrequency ablation and focused ultrasound in treatment of allergic rhinitis which was refractory to medical therapy, and to explore the reliable and safe surgical treatment. METHOD: Eighty-six perennial allergic rhinitis patients were divided randomly into two group. The radiofrequency ablation group included 40 patients and focused ultrasound group included 46 patients. A standard 0 to 10 visual analog scale (VAS) was used to assess the allergic symptoms therapeutic effect before and one year after treatment. RESULT: Allergic symptoms were improved in both two groups one year after treatment. The total VAS score in radiofrequency ablation group decreased from 31.35 +/- 6.16 to 14.16 +/- 4.83 and the total effective power of this group was 87.5% at the twelfth month after surgical. While the total VAS score in focused ultrasound group decreased from 32.86 +/- 5.45 to 21.91 +/- 8.58 and total effective power was 69.6% (all P < 0.01). CONCLUSION This study had demonstrated that the radiofrequency ablation and focused ultrasound appears to be an effective and safe tool for treating allergic rhinitis which was refractory to medical therapy. Compared to focused ultrasound, the radiofrequency ablation seemed to have a longer time therapeutical effect. While the focused ultrasound was more safe and little trauma, which made it possible to the repeated application.

OBJECTIVE: To investigate the positive rates of some allergens in different age groups of allergic rhinitis patients, and to analyze the relationship between serum specific immunoglobulin E(sIgE) and total immunoglobulin E(IgE). METHOD: Six hundred and fifty-three patients with allergic rhinitis, tested by AllergyScreen system, were enrolled in our research. RESULT: The positive rate of sIgE in all patients was 85.5%. The positive rate of dust mite was the highest with the result of 76.3%, and the positive rate of feline or dogs hair was the lowest of 20.3%. The statistical significance of different positive rate of some allergens were found in the different age groups. All the patients were divided into two groups, one was younger than 18 years old group, which including 18 years old and another was older than 18 years old group. Except Mx, the positive rate of other allergens existed statistical difference. The level of serum total IgE could not reflect the positive rate of sIgE completely. CONCLUSION It is an effective and reliable method of the diagnosis of allergic rhinitis to combine the analysis of total serum IgE and sIgE levels with patients clinical manifestations. Different strategies should be employed for the prevention and treatment of allergic rhinitis according to their ages.
