Objective To assess the efficacy and safety of radiotherapy combined with sodium glyci-didazole (CMNa)in treating nasopharyngeal carcinoma by conducting a Meta-analysis.Methods Randomized clinical controlled studies (RCTs)of radiotherapy plus CMNa versus radiotherapy alone in the treatment of nasopharyngeal carcinoma were retrieved from China Biology Medicine disc,China National Knowledge Infrastruc-ture,digital journal of Wanfang Data,China Science and Technology Journal Database,PubMed and Cochrane Library.According to the inclusion and exclusion criteria,data extraction and quality assessment were done by two researchers independently,and clinically important measures were selected.Outcomes were pooled with Rev-Man 5.2.Results The rate of complete remission (CR)in the radiotherapy combined CMNa group was better than that in the radiotherapy alone group in 1 .41 multiple to primary lesion,RR =1 .41 ,95%CI:1 .30-1 .52, Z =8.20,P =0.00.To lymphonodi cervicales metastasis,the rate of CR in the radiotherapy combined CMNa group was better than that in the radiotherapy alone group in 1 .45 multiple,RR =1 .45,95%CI:1 .30-1 .62, Z =6.50,P =0.00.There were no significant differences in the incidence rates of adverse reactions of skin (RR =0.97,95%CI:0.87-1 .08,Z =0.57,P =0.57 ),mucosa (RR =1 .03,95%CI:0.93-1 .15,Z =0.65, P =0.52 )and decrease in white blood cells (RR =0.84,95% CI:0.56-1 .25,Z =0.87,P =0.38). Conclusion In the treatments of nasopharyngeal carcinoma,the rates of CR of primary lesion and lymphonodi cervicales metastasis in radiotherapy combined with CMNa group are superior to the radiotherapy alone group. However,the occurrence rates of adverse reactions in the two groups have no obvious differences.

OBJECTIVETo study the karyotype of four Ephedra plants in order to provide the cytologic evidence for the genetic diversity and identification genetic resources of Ephedra.

METHODThe roots of germinating seeds were used to study the karyotype of four Ephedra plants by staining and slide-preparing technique of mitotic chromosomes.

RESULTthe optimal root-sampling time was about 10: 20 - 10:40 am. Using 0.002 mol x L(-1) 8-Hydroxyquinoline to pretreating the intravital root tips, the optimal pretreatment time for E. Sinica, E. intermedina, E. equisetina and E. przewalskii was 4, 5, 4.5 and 3.5 h, respectively. E. przewalskii and E. equisetina were diploid, E. Sinica and E. intermedina were belonged quadruple. The karyotype formulae of the four species were 2n = 2x = 14 = 2M + 8m + 4sm, 2n = 2x = 14 = 10m + 4st, 2n = 4x = 28 = 20m (2SAT) +8st, and 2n = 4x = 28 = 20m (SAT) + 6st + 2sm, respectively.

CONCLUSIONAll the karyotypes of four Ephedra species were 2A type, which was the symmetric karyotype.

TCM for the improvement of nasal mucosa remodeling after chronic sinusitis endoscopy is the key to the effective prevention of new lesions and recurrence in the surgical cavity mucosa.This article reviewed the mechanism of the nasal mucosa remodeling phenomenon after chronic sinusitis endoscopy and the unique advantages of TCM treatment.Deficiency,phlegm and blood stasis leading to"lung loss"is the perennial root of nasal mucosa remodeling.The treatment is"tonifying deficiency and removing phlegm,invigorating qi and promoting blood circulation",using acupuncture and medicine,and both internal and external treatment to regulate Th17/Treg balance and reduce the inflammatory infiltration;blocking the phosphorylation of MAPK and NF-κB pathway to inhibit TGF-β1-induced myofibroblasts,reduce collagen deposition and inhibit their remodeling,and promote the process of mucosal epithelialization,which can provide ideas for the theoretical and clinical treatment of TCM prevention and treatment of nasal mucosa remodeling.

Objective:To retrospectively analyze clinical efficacy and safety of omalizumab in the treatment of chronic urticaria (CU) in southern Zhejiang, China.Methods:A retrospective observational study was conducted on CU patients who received omalizumab treatment at the First Affiliated Hospital of Wenzhou Medical University from January 1st, 2018 to August 1st, 2021. Through the outpatient follow-up visits, the disease activity, condition control, and quality of life were evaluated using the 7-day urticaria activity score (UAS7) , urticaria control test (UCT) , and dermatology life quality index (DLQI) . In addition, changes in disease condition, recurrence after withdrawal, and adverse events were assessed. Independent-sample t test was used for intergroup comparisons of normally distributed measurement data, Wilcoxon signed-rank sum test or Kruskal-Wallis H test was used for comparisons of non-normally distributed measurement data, and chi-square test or Fisher′s exact test was used for comparisons of enumeration data. Results:A total of 252 CU patients with poor response to antihistamines were included, with a baseline UCT score of 5.0 ± 2.4 points, a UAS7 score of 25.6 ± 6.2 points, and a DLQI score of 17.5 ± 4.7 points; among them, 204 (81.0%) were treated with omalizumab at an initial dose of 300 mg, and 48 (19.0%) with omalizumab at an initial dose of 150 mg. At the end points (12.0 ± 1.4 months after the start of treatment) , an overall control rate of 90.3% (224/248) was achieved after the omalizumab treatment; concretely, 137 (55.2%) patients achieved complete control (UCT = 16 points) , 87 (35.1%) achieved partial control (12 points ≤ UCT < 16 points) , and 24 (9.7%) showed no response (UCT < 12 points) , while 10 with partial response shifted to complete control after dose increase. During the treatment period, recurrence occurred in 50 patients (36.5%) , of whom 32 patients opted for retreatment with omalizumab, and then 30 (93.8%) achieved partial or complete control. Adverse events were reported in 8 patients (3.2%) , and all were mild or moderate.Conclusion:Omalizumab was effective in the real-world treatment of CU, and could improve patients′ quality of life, with a favorable safety profile.

Objective:To observe the clinical effect of arthrocentesis combined with liquid phase con-centrated growth factor(CGF)injection in the treatment of unilateral temporomandibular joint osteoarthri-tis(TMJOA),in order to provide a new treatment option for TMJOA patients.Methods:In this non-randomized controlled study,patients diagnosed with unilateral TMJOA who visited the center for tem-poromandibular joint disorder and orofacial pain of Peking University School and Hospital of Stomatology from June 2021 to January 2023 were selected as research objects.The patients were divided into experi-mental group and control group,which were selected by patients themselves.The experimental group re-ceived arthrocentesis combined with liquid phase CGF injection and the control group received arthrocen-tesis combined with HA injection.Both groups were treated 3 times,once every two weeks.The clinical effect was evaluated by the maximum mouth opening,pain value and the degree of mandibular function limitation 6 months after treatment.The change of condylar bone was evaluated by cone beam CT(CBCT)image fusion technology before and after treatment.Results:A total of 20 patients were included in the experimental group,including 3 males and 17 females,with an average age of(34.40± 8.41)years.A total of 15 patients were included in the control group,including 1 male and 14 females,with an average age of(32.20±12.00)years.There was no statistical difference in general information between the two groups(P＞0.05).There were no statistical differences in the mouth opening,pain value and the degree of jaw function limitation between the two groups before treatment(P＞0.05),and all of them improved 6 months after treatment compared with before treatment(P＜0.05).However,the mouth opening of experimental group was significantly higher than that of control group 6 months after treatment(P＜0.05),and the degree of jaw function limitation was significantly lower than that of con-trol group(P＜0.05).CBCT 2D images showed that the condylar bone of both groups was smoother after treatment than before treatment,and image fusion results showed that 10 patients(50.0％)in the experimental group and 5 patients(33.3％)in the control group had reparative remodeling area of con-dylar bone,and there was no statistical difference between them(P＞0.05).Except for one CGF pa-tient,the other patients in both groups had some absorption areas of condylar bone.Conclusion:The ar-throcentesis combined with liquid phase CGF injection can improve the clinical symptoms and signs of unilateral TMJOA patients in short term,and is better than HA in increasing mouth opening and impro-ving jaw function.CBCT fusion images of both patient groups show some cases of condylar bone repara-tive remodeling and its relevance to treatment plans still requires further study.

Objective:To investigate the effect of posture training on head posture in myogenic temporomandibular disor-ders(TMD)patients with forward head posture. Method:Forty-five myogenic TMD patients(6 male,39 female;age 29.24±6.13y)were recruited from the outpatient rehabilitation clinics of the Ninth People's Hospital of Shanghai Jiaotong University School of Medi-cine from January 2019 to February 2021.Under the design of a prospective controlled study,all patients were randomly divided into the posture training group(23 cases)and the control group(22 cases).The pos-ture training group received posture training for 3 weeks with 30 minutes each time;the control group only re-ceived health education.The patients in two groups received outpatient follow-up after 3 weeks.The maximum mouth opening(MMO)and pain intensity were measured before and after treatment,and the head rotation and craniovertebral angle were measured using the sagittal photograph. Result:The craniovertebral angle of the posture training group(n=22)after treatment were signifiicantly higher than the control group(n=20)(55.3°±2.3° vs 48.4°±4.4°,P＜0.001).The pain score in the posture training group was significantly lower than that in the control group(1.9±0.7 vs 2.9±0.8,P＜0.001).There were no sig-nificant group differences between the improvement of head rotation angle and MMO(P=0.437,P=0.313). Conclusion:Posture training can improve the head posture of myogenic and symptoms in TMD patients.

To demonstrate the effect of AB serum on terminal erythroid differentiation ex vivo.
 Methods: After separation of CD34+ cells from cord blood, the cells were cultured and divided into a control group and an experimental group. The effects of AB serum were examined by the expressions of different markers (GPA, Band3 and α4-integrin) for erythroblast differentiation and enucleation by flow cytometry. 
 Results: The CD34+ cells were successfully differentiated to enucleated red blood cells. There were evident differences among the expressions of GPA, Band3 and α4-integrin between the 2 groups. The percentage of GPA positive cells in the experimental group was bigger than that in the control group in every time point. The expression of Band3 in the experimental group was higher than that in the control group. The expression of α4-integrin in the experimental group was lower than that in the control group. In addition, the enucleation rate in the experimental group was higher than that in the control group.
 Conclusion: AB serum can promote the cell differentiation and enucleation during terminal erythroid differentiation in vitro.
