Objective: To evaluate the inhibitory effect of Yichuanping capsule (易喘平胶囊) on the airway mucus overproduction in asthmatic mice and its mechanism. Methods: Thirty-two male BALB/c mice were randomly divided into normal control group, asthma group, dexamethasone group and Yichuanping capsule (YC) group (n=8 in each group). Asthmatic mouse model was established by intraperitoneal injection of ovalbumin. The number of goblet cells and secretion of mucus were detected with periodic acid-Schiff (PAS) staining, and mucus protein MUC5AC mRNA was detected with reverse transcription-polymerase chain reaction (RTCD*2PCR). Number of total cells and eosinophil in bronchoalveolar lavage fluid (BALF) were counted with special staining. The contents of interleukinCD*24 (ILCD*24) and ?CD*2interferon (IFNCD*2?) in lung tissue were assessed by enzyme-linked immunoadsorbent assay (ELISA). Results: Compared with asthma group, the number of goblet cells, MUC5AC mRNA levels and secretion of mucus in airway were reduced in dexamethasone group and YC group(all P

Objective:To evaluate the effect of presurgical nasal mode(PNM)combined with nasal diorthosis in the treatment of na-sal deformity and incomplete unilateral cleft lip(IUCL)in infants.Methods:35 infants with IUCL were treated by PNM followed by nasal diorthosis and cheiloplasty.The nasal asymmetry was analysed by measurments of nostrils height,nostrils width and nasal colu-mella angle skewness on the photographs at the initial visit(T0),pre-operation(T1),1 week after operation(T2),1 month after opera-tion(T3)and a year after operation(T4).The other 35 infants with IUCL without PNM treatment were served as the controls.Re-sults:Compared with the controls,the symmetry of nostrils height,nostrils width,nasal columella angle skewness in PNM treated children were significantly improved at T0-T1 and T1-T2(P ＜0.05).there was no significant difference at T2-T3 and T3-T4(P >0. 05).Conclusion:Nasal asymmetry can be improved by presurgical nasal mode treatment followed by preliminary nasal deformity di-orthosis and cheiloplasty.

Objective:To study the correlation between early postsurgery phonetic acquisition of speech stop and speech outcomes of young children.Methods:28 children with cleft palate were included in the study.An one-stage palatal repair procedure was per-formed by one surgeon for the children before the age of 1 8 months.Naming tests were used in the speech therapy room when the chil-dren were aged 23 months and 30 months.Stop consonant inventory number,percent correct consonants(PCC),percent correct man-ners(PCM)and percent correct places(PCP)were analyzed.Results:Number of stop consonant was significantly correlated with PCC,PCM and PCP at 24 and 30 months of age in the children.Coefficient of determination between stop consonant number and PCC was 0.535.Conclusion:Speech stop may be used as the “sensitive sound”for the analysis of speech development of the chinese children aged 2-3 years after cleft palate repair and as the individuation guideline to determine the best assessment and therapy time.

Objective: Velopharyngeal insufficiency (VPI) is a common postoperative sequela secondary tocleft palate. It could significantly impairpatients′living quality. Treatment of VPI includes surgery and speech therapy, but the reported success rates are inconsistent. A consensus in the literatures is needed, to guide procedure selection for patients with VPI. Methods: This is a retrospective study on management options for patients with VPI.This study systematically introduces the assessment, management plan and treatment effect of VPI, in the Craniofacial center of Hospital Stomatology of Xi′an Jiaotong University.The challenges of VPI diagnosis and treatment with cleft palate are discussed in-depth. Results: Most patients with VPI underwent evaluation and treatment (surgical or/and speech therapy) had speech improvement. The average value of hypernasality decreased from 3.67 before interventions to 1.57 after interventions.A multidisciplinary team using multi-modal to evaluate velopharyngeal function and speech. All patients had no bleeding, would dehiscence or fistula postoperatively. The difficulty of stimulability test was significantly reduced. Fourteen patients completed speech therapy, with the averaged treatments period of 3 months. Conclusions Speech pathologist is the manager of speech rehabilitation of cleft palate patients with VPI. The operation skill plays a key role in the treatment of VPI. Detailed diagnostic information is important for performing excellent surgical techniques. The cooperation of surgeon and speech pathologist, could be helpful to achieve the final speech rehabilitation.

Objective To explore the hot topics and the research trend of traditional Chinese medicine treatment of chronic obstruc-tive pulmonary disease in 2017-2021,and to aware the cooperation among authors and institutions in the field.Methods Literature on TCM treatment of chronic obstructive pulmonary disease published in CNKI and PubMed in 2017-2021 was searched,and CiteSpace 5.8 R3 was used to visualize the authors,research institutions and keywords of the included literatures.Results A total of 3082 Chinese literatures and 1093 English literatures were included.In 2017-2021,the trend of publication has always shown a steady growth,and there was a lack of communication and cooperation among authors and teams.Keywords visualization map showed 18 clusters and 20 emer-gent words.Conclusion Traditional Chinese medicine treatment of chronic obstructive pulmonary disease is mainly focused on syndrome type,treatment methods,disease mechanism and related curative effect indicators,and the syndrome differentiation analysis and clinical curative effect evaluation of traditional Chinese medicine compounds are still the main forces at present.As the patients quality of life is becoming more and more attention,how to strengthen pulmonary rehabilitation education,improve patient compliance,and expand the lo-cation and area of pulmonary rehabilitation is one of the current research trends.

ObjectiveThrough a randomized， double-blind， double-simulation， positive-control， multicenter design， this study aimed to analyze the relationship between the dosage， efficacy， and safety of Pudilan anti-inflammatory oral liquid in treating acute pharyngitis/tonsillitis in adults caused by bacterial infection and validate the regulatory effect of Pudilan anti-inflammatory oral liquid on inflammatory markers such as serum amyloid A （SAA）， C-reactive protein （CRP）， white blood cells （WBC）， neutrophil percentage （NE%）， and erythrocyte sedimentation rate （ESR）， thereby exploring the feasibility of using Pudilan anti-inflammatory oral liquid as a substitute for antibiotics in the treatment of infectious diseases and providing a basis for rational clinical medication. MethodUsing a stratified randomized， double-blind， double-simulation， positive-control， multicenter design， 220 participants were enrolled from nine centers. The participants were randomly divided into three groups at 1∶1∶1 — a Pudilan anti-inflammatory oral liquid 20 mL group （73 cases）， a Pudilan anti-inflammatory oral liquid 10 mL group （73 cases）， and a control group （amoxicillin group， 74 cases）. The treatment course was 7 days. The study observed parameters including the total effective rate of sore throat， onset and disappearance time of sore throat， health status score， treatment time， and inflammation markers. Result①Dataset division： The 211 cases were included in the full analysis dataset （FAS）， 208 cases were included in the per-protocol dataset （PPS）， and 218 cases were included in the safety dataset （SS）. ② Efficacy evaluation： There were statistically significant differences （P<0.05） in the comparison of the three groups regarding the total effective rate of sore throat， disappearance time of sore throat， and health status. Both the 20 mL and 10 mL groups were non-inferior to the control group， and there was a statistically significant difference between the 20 mL and 10 mL dosage groups （P<0.05）. There was no statistically significant difference in the comparison of onset time of sore throat among the groups. CRP， WBC， and NE% of patients in all three groups significantly decreased on the 7^th day of treatment compared with those before treatment （P<0.01）. ③Safety evaluation： Adverse events mainly occurred in various examination indicators. There were no statistically significant differences in the comparison between groups， and no adverse reactions or serious adverse events occurred. ④Economic evaluation： The increased cost of the 10 mL and 20 mL dosage groups was entirely justified as compared with that in the control group. When comparing the 10 mL and 20 mL dosage groups， the 10 mL dosage group was deemed less advantageous. ConclusionPudilan anti-inflammatory oral liquid can be used alone as an alternative to antibiotics in the treatment of acute pharyngitis/tonsillitis caused by bacterial infection. It demonstrates good safety and can lower inflammation markers such as CRP， WBC， and NE%， suggesting its potential to reduce the body's inflammatory response. Its mechanism of action may be related to its multi-target regulatory mechanism.
