Objective To explore the effect of the ongoing time of applying Musk Xiaochuan in the treatment of stable asthma and obtain the optimal therapy.Methods 129 cases of patients with stable asthma were randomly divided into 3h group (29 cases), 4h group (34 cases), 5h group (31 cases), 6h group (35 cases) according to the different applying time.The selection of points, applying frequency, treatment course remained the same, and then “dog day” was selected to apply Musk Xiaochuan paste for treatment.The asthma quality of life and asthma control pre-and post-treatment were observed.Results After applying, the asthma control questionnaire (ACQ) score difference value in 3h group was not preferable than the other groups, with no significant difference.The asthma quality life questionnaire (AQLQ) total score difference value in 4h group was significantly higher than the other 3 groups, with significant difference(P<0.05).The activity limitation score difference value and mental health difference value of AQLQ in 4h group were significantly higher than the other 3 groups, with significant difference(P <0.05), the asthma symptom score and stimulus response score difference values, health care for their own score difference value also showed significant effect (P<0.05).Conclusion The difference of the ongoing time of applying Musk Xiaochuan has different efficacy in the treatment of stable asthma, the efficacy of applying for 4h is better than 3, 5,6 h, while it could not determine the best time in asthma control.

Objective To compare the clinical value of two kinds of imaging methods including CT and MRI in early diagnosis of acute multiple cerebral infarction. Methods The imaging data of CT and MRI of 108 patients with acute multiple cerebral infarction were analyzed. The total detection rate, the detection rate in different time periods,the number and area of detected lesions and the inspection time of CT and MRI in early diagnosis of acute multiple cerebral infarction were compared. Results The total detection rates of patients with acute multiple cerebral infarction by CT and MRI were 57. 41%,96. 30%,respectively. The total detection rate of MRI was significantly higher than CT(χ2 =9. 73,P<0. 05). The detection rates of patients with acute multiple cerebral infarction for onset within 24h and 24-72h by MRI were significantly higher than CT(χ2 =18. 54,16. 20,all P<0. 05). There was no significant difference in detection rate of patients with acute multiple cerebral infarction for onset >72h between CT and MRI(P>0. 05). The number of detected lesions of patients with acute multiple cerebral infarction by MRI was significantly more than CT(t=2. 39,P<0. 05). The area of detected lesions and the inspection time of patients with acute multiple cerebral infarction by MRI were significantly less than that by CT(t =2. 43,2. 60,all P <0. 05). Conclusion Compared with CT, MRI in the early diagnosis of acute multiple cerebral infarction can effectively improve the detection rate in early stage, avoid the missed diagnosis of small lesions and is helpful to shorten the examination time.

Objective: To explore the visuospatial memory characteristics of school-age children with exotropia and to analyze associated factors. Methods: Based on a case-control study,45 exotropia children aged 8-12 years and 45 normal control children were recruited from 2017-2019. The "tapping test" was used to evaluate the visuospatial short-term and working memory of children. Results: There was no significant differences in the scores of visuospatial short-term memory between the exotropia group and the control group [(7.64±1.69)(8.00±1.66)，t=-1.00，P=0.32)]. The scores of visuospatial working memory in the control group were higher than those in the exotropia group [(5.98±1.23)(6.80±1.53)，t=-2.81，P=0.01)]. In the reverse tapping test,the better the near stereopsis was,the higher the score was (B=0.78,95%CI=0.23-1.33,P=0.01),and the constant exotropia children performed better than the intermittent exotropia children(B=1.25,95%CI=0.16-2.24,P=0.03). Conclusion Visuospatial working memory is impaired in school-age children with exotropia,and the visuospatial working memory of exotropia children is affected by the near stereopsis and exotropia constancy.

Objective: To understand the characteristics of rapid naming in exotropia children, and to analyze the influence of clinical indicators related to exotropia on the rapid naming. Methods: A total of 45 exotropia children were recruited according to the diagnostic criteria of consensus of strabismus classification experts (2015) from the Zhongshan ophthalmic center as the case group, and 45 children of the same age, gender and parental educational status were recruited as the control group without any ocular diseases. All children were evaluated the ability of the rapid naming by classical rapid naming test. Results: The letter rapid naming time of children with exotropia was longer than that in control group [(26.87±10.18)(21.98±7.29)s], and the difference was statistically significant (t=2.73, P=0.01), however there was no significant correlation between strabismus degree, symptom duration, AC/A ratio, disease classification, simultaneous vision, the near stereopsis, the far stereopsis and the letter rapid naming in the clinical indicators of exotropia (r=-0.16, 0.23, 0.20, 0.06, 0.09, 0.05, 0.20, P>0.05). Conclusion Rapid naming might be impaired among children with exotropia, with no significant correlation between this defect and its clinical indicators.

Objective: To evaluate the stability and aesthetic effect of a xenogeneic collagen matrix (mucograft) on achieving an adequate keratinized mucosa width (KMW) around implants and to provide a reference basis for the clinical application of xenogeneic collagen matrix materials. Methods: The hospital ethics committee approved the study protocol, and the patients provided informed consent. Twenty patients with a KMW<2 mm at the buccal implant site who were treated in Binzhou Medical University Affiliated Yantai Stomatological Hospital from July 2020 to September 2022 were included, and a total of 36 implants were included. The mean age of the patients was (52.0±10.4) years, of which 18 were females and 2 were males. They were divided into a free gingival graft group (FGG, control group) and a xenogeneic collagen matrix group (test group) according to different graft materials. The incremental effect of the KMW on the buccal side of the implant and the mucosal shrinkage rate was measured at 1 month and 3 months after the operation. The mucosal scar index (MSI) was evaluated after the operation. Results: At 3 months postoperatively, the KMW was (3.67 ± 1.06) mm in the control group and (2.96 ± 0.98) mm in the test group, and the difference was statistically significant (t = 2.076, P<0.05). The KMW shrinkage rate was (33.34 ± 16.30) % in the test group and (22.05 ± 15.47) % in the control group at 1 month postoperatively and (51.95 ± 12.60) % in the test group and (37.44 ± 16.30) % in the control group at 3 months postoperatively, with statistically significant differences between the two groups at the same time points (P<0.05). Three months after surgery, the test group showed significantly better outcomes than the control group in terms of the five scar indicators (scar width, scar convexity, scar color, scar trace, and overall appearance), and the difference was statistically significant (P<0.05). Conclusion Xenogeneic collagen matrix can increase the peri-implant KMW and achieve a more natural and coordinated soft tissue aesthetic effect but with a higher shrinkage rate.
