Objective To know the influence of psychological intervention on delivery results of par-turient women, and then reference to certain effective psychological nursing cares for clinical field. Methods Divided 226 partreient women of spontaneous labor into the experimental group and the control group randomly, there were 113 eases in each group. Traditional routine nursing cares was used in the control group, psychological intervention was used in the experimental group in addition. Compared the condi-tion of birth process and the incidence rate of labor-related complications between the two groups. Re-sults There were significant differences between the two groups about all the indexes which had indicated the delivery. Conclusions Correct psychoanalysis and proper nursing intervention and effective release the pains for parturient women, and then decrease the incidence rate of medical negligence.

Objective:To investigate the changes of occlusal plane in the process of retracting maxillary anterior teeth with different vertical traction force.Methods:The three dimensional finite element model of maxillary anterior teeth en-masse retraction by micro-implant was constructed with cone beam CT scanning and MIMICS and ANSYS software.Then the movement tendency of tooth and the changes of the maxillary occlusal plane was calculated when the vertical traction force was 0,0.5,0.75 and 1 N in the process of en-mass retraction,respectively.Results:Lingual tipping of anterior teeth,distal tipping of the first molar and the maxillary occlusal plane clockwise rotation by the retraction forces were observed.With the vertical traction force increasing,lingual tipping of anterior teeth and distal tipping of the first molar were decreased,and the occlusal plane clockwise rotation was prevented.Conclusion:The upper dentition movement and occlusal plane rotation can be changed effectively by the vertical traction with different force.When retract anterior teeth,0.5-0.75 N vertical traction force is beneficial to prevent clockwise rotation of the maxillary occlusal plane.

Objective To investigate the correlation of clinicopathological features with osteopontin and aquaporin-1 expres-sion in laryngeal carcinoma.Methods From August 2011 to December 2014 in Dongfeng General Hospital,80 laryngeal cancer specimens and adjacent normal tissue samples were selected,all samples were carried out osteopontin and aquaporin Immunohistochemical analysis expression and clinicopathological characteristics and correlation analysis.Results Osteopon-tin staining particles and aquaporin-1 were located in the stromal cells,yellow dye.In cancer tissue,osteopontin and aquapor-in-1 positive granules were mainly located in the cytoplasm of cancer cells,diffuse shading,coloring deeper place near nests. The positive expression rates of osteopontin and aquaporin-1 in the laryngeal carcinoma were 70.0% and 56.3% respective-ly,the positive rates in the adjacent tissues were 5.0% and 7.5% respectively that compared to the differences were statisti-cally significant (P <0.05).In 80 cases of laryngeal carcinoma.The expression of osteopontin and aquaporin-1 in different clinical stages,differentiation and lymph node metastasis tissues were statistically significant (P <0.05).Spearman correla-tion analysis showed that the osteopontin and aquaporin-1 in laryngeal carcinoma were positively correlated (P <0.05).Con-clusion Osteopontin and aquaporin-1 expression in laryngeal carcinoma were showed high status,and the clinical stage,de-gree of differentiation and lymph node metastasis were significantly correlated that can work together to promote tumor inva-sion and metastasis.

[ABSTRACT]OBJECTIVETo investigate the therapeutic effect of early combination treatment with intratympanic glucocorticoid injection for sudden sensorineural hearing loss(SSNHL).METHODSTotal of 178 patients with diagnosis of SSNHL, including 44 with hearing loss at middle-low frequencies,50 at high frequencies,44 at all frequencies and 40 at total deafness, were randomly divided into combination treatment group (CT group) and systemic oral prednisone group (OP group).CT group (82 patients) received intratympanic administration of methylprednisolone and oral prednisone in tapering doses. Pure-tone threshold audiometry (PTA) was performed at week 8 after beginning of therapy. RESULTSIn middle-low frequencies, the final PTA and PTA improvement were 26.14±24.82 dB and 42.23±1.61 dB in CT group respectively, and were 37.91±13.98 dB and 30.00±13.30 dB in OP group respectively (both P<0.05). In high frequencies, all frequencies and total deafness SSNHL group, the differences of the final PTA and PTA improvement were not statistically significant in both groups. The PTA improvement in CT group for total deafness (26.52±14.03) dB was more than that of OP group (22.06±11.17)dB (t=2.361,P<0.05). In middle-low frequencies, the recovery rate was 72.73%(16 cases) in CT group, and 40.91% (9 cases) in OP group, the difference was significant (χ2=4.539,P<0.05), but not in apparent effective rate, effective rate and total effective rate. In high frequencies, all frequencies and total deafness, there were no significant differences in therapeutic effect. The recovery rate of total CT group (40.24%) was significantly increased compared with that of OP group (26.04%)(χ2=4.061,P<0.05), the differences of apparent effective rate, effective rate and total effective rate were not statistically significant in both groups.CONCLUSIONFor low-middle frequencies SSNHL, the early combination treatment with intratympanic glucocorticoid injection leads to higher hearing recovery and therapeutic effect compared with traditional oral prednisone. Systemic application should be applied for high frequencies, all frequencies and total deafness of SSNHL.
