Objective To investigate the preference of the postgraduates in school for work and their psychological changes based on the analysis of the employment status of postgraduates majoring in clinical science of stomatology in Anhui medical university in recent five years in an aim to provide preemployment counseling.Methods The employment status of postgraduates majoring in clinical science of stomatology in affiiated stomatological hospital of Anhui medical university in recent five years (2006 -2010) was summed up.Questionnaire of employment preference and the psychological pressure was conducted in 66 postgraduates majoring in clinical science of stomatology (2008 -2010 grade).Results The employment rate of provincial first-class hospitals was obviously decreased in the recent five years while that of municipal first-class hospitals was increased gradually.The number of postgraduates willing to work in the municipal first-class hospitals was reduced while that willing to future their study and work in the non first-class hospitals was increased.Psychological pressure was univcrsally existed in students and did not get released.Conelusion As the employment situation for postgraduates majoring in clinical science of stomatology changes,the preference for work and psychological pressure of the postgraduates also undergo corresponding changes.Targeted measures can be formulated to work out the problem based on the understanding of these changes.Meanwhile,adjustment should be made in the training methods and employment guidance for postgraduates majoring in clinieal science of stomatology.

Objective:To compare the effectiveness and safety of all-suture anchors and single-row suture anchors for rotator cuff repair.Methods:A prospective randomized controlled study was conducted to analyze the clinical data of 50 patients with rotator cuff tear admitted to Second Affiliated Hospital of Zhejiang University School of Medicine between July 2019 and September 2021. They were divided into two groups according to the random table: 25 patients to receive repair with single-row suture anchors (control group) and the other 25 with all-suture anchors (trial group). Visual Analogue Scale (VAS), University of California, Los Angeles (UCLA) shoulder score, American Shoulder and Elbow Surgeons (ASES) score and shoulder range of motion were compared between the two groups before surgery, at 3 months after surgery and at the last follow-up. The rotator cuff retear rate of the two groups was evaluated according to Sugaya classification at 6 months after surgery. Breakage or anchor loosening during surgery, healing of incision and presence of infections or neurological complications after surgery, and change of the anchor position and periosteal reaction at the insertion site at 3 and 6 months after surgery were observed in the two groups.Results:A total of 50 patients with rotator cuff tear were involved in this study, including 17 males and 33 females, aged 40-73 years [(59.1±10.3)years]. All patients were followed up for 6-9 months [(6.7±1.0)months]. The differences in VAS, UCLA shoulder score, ASES score, and shoulder range of motion between the two groups were statistically insignificant before surgery (all P>0.05). The VAS at 3 months after surgery and at the last follow-up in the control group was 2.0 (2.0, 4.0)points and 2.0 (0.0, 2.0)points, respectively, with no statistical differences from 2.0 (2.0, 2.0)points and 2.0 (0.0, 2.0)points in the trial group (all P>0.05). In the control group, the UCLA shoulder score and ASES score at 3 months after surgery and the ASES score at the last follow-up were (25.1±4.5)points, 78.8 (71.6, 85.8)points and 85.8 (85.8, 93.0)points, respectively, with no statistical differences from (26.8±4.7)points, 85.8 (82.3, 85.8)points, and 92.8 (85.8, 100.0)points in the trial group (all P>0.05). At the last follow-up, the UCLA shoulder score of the control group was (29.2±3.9)points, which was lower than that of the trial group [(31.6±2.4)points] ( P<0.05). The differences in shoulder motion between the two groups at 3 months after surgery and at the last follow-up were not statistically significant (all P>0.05). The VAS, UCLA shoulder score, and ASES score at 3 months after surgery and at the last followup in both groups were significantly improved compared to their preoperative values (all P<0.05); further improvements were observed at the last follow-up compared with those at 3 months after surgery (all P<0.05). The rotator cuff retear rate at 6 months after surgery was 16.7% (4/24) in the control group, not statistically different from 4.3% (1/23) in the trial group ( P>0.05). There were no incidences of anchor loosening or breakage during surgery. All incisions were healed after surgery, with no infections or neurological complications. No grades II to III periosteal reactions at the anchor insertion sites were observed in either group at 3, 6 months after surgery. The percentage of patients with grade 0 periosteal reaction at the anchor insertion site at 3 months after surgery was 4.2% (1/24) in the control group, significantly lower than 30.4% (7/23) in the trial group ( P<0.05). Conclusion:All-suture anchors and single-row suture anchors are effective in rotator cuff repair, but the former results in better shoulder function and fewer periosteal reactions in the anchor insertion site in the early stage.
