Objective To study the differences in the inclination of lower incisors among the female patients with beautiful profiles in different vertical skeletal types so as to provide the clinical treatment design for a certain guiding. Methods 137 cephalometric films of female patients with beautiful profiles were selected and divided into three groups based on the vertical facial types(∠SNMP):small degree(n = 31),average degree(n = 89) and larger degree groups(n=17). The angles of∠L1/MP and∠L1/A-Pog were measured and treated with covari-ance analysis for detecting the differences between the groups. Results The index of L1-MP(°)was the smallest in the larger degree group,the largest in the small degree group and average in the average group,with significant differences between the three groups(F = 17.38,P < 0.001). There was no significant differences in ∠L1/A-Pog (°)(F=2.61,P>0.05). Conclusion Lower incisors have compensatory inclined lingually in the group of higher mandible angle,but labially in the group of lower mandible angle.

Objective: To explore the intervention techniques of group counseling leader ("group leader") during group counseling process. Methods: The analysis material of intervention techniques was 11 sessions in two unstructured counseling groups. The analysis unit was every dialogue paragraph in the leader'soral response in the group counseling process. And the leaders' intervention techniques emerging in the video and verbatim transcription were coded according to adapted coding manual. Results: Totally 48 types of techniques were identified, that were grouped into 4 categories, including basic communication and reaction technique, exploring and influencing technique, facilitating technique, action and intervention technique. From the perspective of the single group counseling activity, techniques of basic communication and reaction were used more in the early and middle stage of an activity. Techniques of exploring and influencing and techniques of action and intervention were used more in the middle and later stage. And facilitating techniques were more used in the early and later stage. From the perspective of the whole grouping counseling process, techniques of basic communication and reaction and techniques of exploring and influencing were two primary types of intervention techniques. Frequency of using exploring and influencing techniques reached its peak in the intermediate stage of the group counseling process. The use of facilitating technology was gradually reduced. Conclusions: Techniques of basic communication and reaction are basic intervention techniques in group counseling, while techniques of exploring and influencing and techniques of action and intervention could be used on the basis of the development of the group. And facilitating techniques could facilitate to open the group and deepen the achievement of group counseling.

Objective:To explore group leaders' intervention intensions during group counseling process. Methods: The Interpersonal Process Recall (IPR) was applied to collect leaders' intervention intensions in 11 sessions of 2 unstructured counseling groups. Leaders' intervention intensions were coded according to coding manual. Results: Totally 29 types of intervention intensions were identified and grouped into 10 categories. The 3 intervention intensions with the highest frequency were"access to information and evaluation", "promoting awareness" and "expressing support for group members". The intervention intensions of establishing a group culture and promoting group cohesion mainly appeared in the early stage of group counseling. The intervention intension of dealing with emotion mostly appeared in the middle stage. The intervention intension of promoting awareness appeared a lot in the early and middle stages of group development The intervention intention of expressing support for group members was salient at the initial and final stages of group counseling. Conclusion: There may be diverse intervention intensions in the process of group counseling. Group leaders could pay attention to interpersonal interaction, giving consideration to both individuals and groups.

OBJECTIVETo analyze the diagnostic value of larval excretory-secretory antigen in Angiostrongylus cantonensis (LESA) infection.

METHODSA.cantonensis larvae harvested from mice brain were cultured in vitro. The LESA and the adult worm antigens of A.cantonensis (AWA) were collected and analyzed using SDS-PAGE and Western blotting. Two ELISA systems were established using the two antigens (LESA-ELISA and AWA-ELISA) to detect the serum spectra from different sources.

RESULTSSDS-PAGE and Western blotting displayed fewer protein and antigen bands for LESA than for the adult antigen. Two distinct bands of LESA (with relative molecular masses of 40 000 and 26 000) showed reactivity with the sera from patients with A. cantonensis infection. The serum levels of IgG and IgM antibodies to LESA increased at the beginning of infection in mice, reaching the peak on day 5 after infection and decreased on day 10. Compared with AWA-ELISA, LESA-ELISA showed a lower seropositive ratio in suspected patients with A.cantonensis, with also a lower cross-positive ratio in patients with schistosomiasis and clonorchis sinensis.

CONCLUSIONLESA possesses fewer antigen reaction bands than AWA. Although with a slightly lower positive ratio than AWA, LESA has a higher specificity for detecting serum antibodies in suspected cases of A.cantonensis infection, and therefore shows a potential for the diagnosis of angiostrongyliasis especially in the early stage and in current infection.

Objective: To evaluate the methodological quality of papers that performed meta-analyzed and systematically reviewed acupoint selections for the treatment of functional dyspepsia (FD) and to identify the ideal acupoint combinations for FD. Methods: Chinese databases including China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), China Biology Medicine (CBM), and Wanfang Database, as well as English databases including PubMed, Embase, and Cochrane Library were searched to retrieve papers about meta-analysis and systematic literature reviews on acupuncture for FD. The time span for the paper retrieval was set from the foundation of the databases to April 30, 2022. The Veritas scores of the papers based on their publication year, study type, Assessment of Multiple Systematic Reviews 2 (AMSTAR2), Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), heterogeneity, and publication bias were rated to assess the methodological quality of the included studies. Then, randomized controlled trials (RCTs) were extracted from those meta-analysis papers or systematic literature reviews for analyzing acupoints frequency, meridian frequency, and association rules with the use of R software (V 4.3.1). Results: Eight meta-analysis papers were included in the study after screening. The mean Veritas scores of the papers based on publication year, type of study, AMSTAR2, PRISMA, heterogeneity, and publication bias were 4.50, 8.00, 4.63, 4.63, 4.50, and 6.13, respectively. The analysis of the scores revealed insufficiencies in the reviews pertaining to the methodology, comprehension of the research strategy, detailed list of excluded studies, sources of funding, assessment of potential bias risks impact on meta-analysis results in each study, explanation of heterogeneity, and identification of potential conflicts of interest. Furthermore, a total of 85 RCTs were obtained from the eight meta-analysis papers involving 85 acupuncture prescriptions and 67 acupoints for subsequent data mining. The most commonly used meridian was Stomach meridian of Foot-Yangming (ST). Zusanli (ST36), Neiguan (PC6), Zhongwan (CV12), Taichong (LR3), Tianshu (ST25), Gongsun (SP4), Weishu (BL21), Pishu (BL20), Neiting (ST44), and Yinlingquan (SP9) topped the list of frequently selected acupoints. Additionally, a total of 28 association rules were identified, including 10 second-order, 15 third-order, and 3 fourth-order association rules. The top-ranking association rules in each order were “Neiguan (PC6) → Zusanli (ST36)” “Zhongwan (CV12) + Neiguan (PC6) → Zusanli (ST36)” and “Zhongwan (CV12) + Taichong (LR3) + Neiguan (PC6) → Zusanli (ST36)”, respectively. Conclusion Acupuncture could alleviate the clinical symptoms of FD. However, the quality of methodology applied in the meta-analysis papers on the subject needs to be improved. Through data mining, a combination of Neiguan (PC6), Zusanli (ST36), Zhongwan (CV12), and Taichong (LR3) was identified as an essential acupoint combination for the treatment of FD.
