[Clinical observation of acupuncture at Qianlianquan (Extra) and eight confluent points on chronic pharyngitis].

OBJECTIVE: To observe the clinical therapeutic effect of acupuncture at Qianlianquan (Extra) and eight confluent points on chronic pharyngitis. METHODS: A total of 42 patients with chronic pharyngitis were randomized into an observation group and a control group, 21 cases in each one. In the observation group, acupuncture was applied at Qianlianquan (Extra) and eight confluent points [Neiguan (PC 6), Waiguan (TE 5), Lieque (LU 7), Houxi (SI 3), Gongsun (SP 4), Shenmai (BL 62), Zhaohai (KI 6) and Zulinqi (GB 41)], once a day, 6 days as one course, with an interval of 1 day between the courses, 4-course treatment was required. In the control group, Qinghou Liyan granules were taken orally 5 g each time, 3 times a day, 7 days as one course and 4 courses were required. Before and after treatment, symptoms and signs scores of chronic pharyngitis and the contents of IL-2 and TNF-a in serum were compared in the two groups. RESULTS: Compared before treatment, symptoms and signs scores of chronic pharyngitis and the contents of IL-2 and TNF-a in serum were improved in both groups (all P<0.05), and the changes in the observation group were superior to the control group (all P<0.05). The total effective rate was 90.5% (19/21) in the observation group, which was superior to 81.0% (17/21) in the control group (P<0.05). CONCLUSION: The therapeutic effect of acupuncture at Qianlianquan (Extra) and eight confluent points on chronic pharyngitis is superior to conventional Chinese patent medication treatment by Qing Liyan granules.

[Association between cervical vertebral maturation stages and dental calcification stages in patients with unilateral complete cleft lip and palate].

OBJECTIVE: The purpose of the study is to investigate the relationship between dental calcification stages (DCS) and cervical vertebral maturation stages (CVMS) in patients with unilateral complete cleft lips and palates (UCLP) and to provide a theoretical basis for the treatment time selection of cleft lip and palate (CLP) patients. METHODS: A total of 123 UCLP patients and 215 non-CLP subjects were selected. The DCS of the left mandibular canine, premolar, and second molar in non-CLP subjects and on both cleft sides of UCLP patients were assessed utilizing the Demirjian method. CVMS was observed utilizing the Baccetti method. The results were analyzed by Spearman rank correlation, and the correlation coefficients were compared. RESULTS: There was a correlation between the CVMS and the DCS of the left mandibular canine, the first premolar, the second premolar, and the second molar in the non-CLP subjects and on both cleft sides of the UCLP patients (r=0.762-0.864, P<0.05; r=0.809-0.914, P<0.05, respectively). The correlation between the CVMS and the DCS of the mandibular first premolar was highest among the UCLP patients. Except for the first and the second premolars of UCLP females, the correlation between the DCS and the CVMS of the other teeth did not differ among the non-CLP subjects (P>0.05). CONCLUSIONS: DCS can be utilized as a biological index to determine the growth development statuses. The correlation between the CVMS and the DCS of the mandibular first premolar was the highest.

[The symmetry of nasal maxillary complex of patients with unilateral complete cleft lip and palate at the stage of mixed dentition-A cone beam CT study].

PURPOSE: To investigate the symmetry of nasal maxillary complex in the three-dimensional directions of patients with unilateral complete cleft lip and palate(UCLP) at the stage of mixed dentition. METHODS: Craniofacial cone-beam CT(CBCT) images of 20 UCLP patients at the stage of mixed dentition were selected. Three-dimensional reconstruction of bone tissue was carried out by Mimics software, nasal root point and 32 markers with the same name of the healthy side and the cleft side of the nasal maxillary complex were traced, three-dimensional reference planes were set up, then the distances between the points to the three-dimensional planes were measured respectively. SPSS 22.0 software package was used to analyze the data. RESULTS: In the horizontal direction, compared with the non-cleft side, the width of the cleft side of the maxilla at INM and SPC was smaller, the width of maxilla at LPA and SPr was larger, the differences were statistically significant (P<0.05). In the sagittal direction, compared with the non-cleft side, the depth of LPA, Maz and SPr at the cleft side was larger, the depth of SPM and SPC was smaller, the differences were statistically significant (P<0.05).In the vertical direction, the positions of LPA, INM and Maz at the cleft side was lower than the non-cleft side, SPC and SPr were higher, the differences were statistically significant(P<0.05). The remaining points had no significant difference (P>0.05). CONCLUSIONS: The nasal maxillary complex of UCLP patients at the stage of mixed dentition is asymmetric in three directions. The asymmetric locations were mainly located in the nasal cavity and alveolar bone. No obvious asymmetry is found in the orbital region and the maxillary region far from the cleft.
