Objective This study simulated clinical implant surgery using squeeze technique by establishing a rational animal model.We investigated the microscope image in order to observe the agglutination of the cancellous bone after being compressed.Methods The cancellous bone in condyles of dog femur had been chosen as the experimental position,the implant holes were prepared using squeeze technique according to different compressing extent(0,0.6,1.2,2.0mm),and then the corresponding implants were inserted into them.After different healing periods(1 week,2 weeks,4 weeks,12 weeks),the mongerl dogs were sacrificed and the hard tissue slices were made,then the architecture of the cancellous bone was observed using microscope.Results The architecture of the cancellous bone was changed obviously by squeeze technique in 1 week,2 weeks and 4 weeks hard tissue slices.After being compressed,the bone trabecula around implants was compact.Conclusion The clinical implant surgery using squeeze technique helps improve peri-implant bone density,which is good for obtaining primary stabilities of implants.

Objective To investigate the substantia nigra (SN) and brainstem raphe (BR) echogenic features of Parkinson's disease (PD) patients with musculoskeletal pain.Methods A total of 115 PD patients recruited in the Second Affiliated Hospital of Soochow University from October 2014 to May 2016 were assessed with the following rating scales:Unified Parkinson's Disease Rating Scale (UPDRS),Hoehn and Yahr Staging Scale (H/Y),Hamilton Rating Scale for Depression (HRSD),Beck Depression Inventory Ⅱ (BDI-Ⅱ) and Visual Analogue Scale (VAS).All the subjects underwent transcranial sonography during the clinical evaluation.And the patients were divided into PD with musculoskeletal pain (n =54) and PD without musculoskeletal pain (n =61) groups,or PD with depression(n =74) and PD without depression(n =41) groups.Results Compared with PD patients without pain,PD patients with musculoskeletal pain had higher scores of UPDRS-Ⅱ,-Ⅲ,HRSD,BDI,NMSQ and H/Y (UPDRS-Ⅱ score:12.56 ±6.01 vs 8.79 ±4.38,t =-3.801,P ＜0.01;UPDRS-Ⅲ score:24.43 ± 12.43 vs 20.07 ± 11.12,t=-1.986,P=0.049;HRSD score:11.65-±6.94 vs 8.38-±5.36,t=-2.844,P=0.005;BDI score:14.09 ±6.20 vs 9.74 ±6.00,t =-3.826,P ＜0.01;NMSQ score:8.57 ± 4.06 vs 5.60 ± 3.38,t=4.193,P＜0.01;H/Y:2.0(1.5,2.6) vs 1.5(1.0,2.0),Z=-3.011,P=0.003).Positive BR was more frequent in depressed than in non-depressed PD patients without pain (63.6％ vs 14.3％;x2 =15.25,P ＜0.01).Positive BR was positively associated with sex(r =0.228,P =0.014),age(r =0.184,P =0.049),disease duration (r =0.196,P =0.035),and depression (r =0.396,P ＜ 0.01).However,positive BR did not correlate with musculoskeletal pain.No correlation was found between positive SN and clinical characteristics of PD patients.Conclusions PD patients with musculoskeletal pain have worse activity of daily living,more severe motor symptoms,more non-motor symptoms,and are more depressed.SN and BR echogenecity do not correlate with musculoskeletal pain,however,hypoechogenic or interrupted BR is associated with depression in PD patients.

Objective To explore the effective management of post-operation infections through clinical pharmacists participating in the treatment of a gastric cancer patient with post operation abdominal infection and cellulitis. Methods Clinical pharmacists provided an rational anti-infective treatment plan with the combination of pharmacy and clinical practice, conducted medication education for the patient, and participated in the process of pharmacy care for the patient. Results Physicians modified the medication plan according to the recommendations from the clinical pharmacists. The patient’s infection was effectively controlled and the symptoms were alleviated. Conclusion With their professional knowledge, clinical pharmacists can select the best antibacterial drug regimen for the treatment of post-operation infections and provide patients with optimal pharmaceutical care.

Objective: To evaluate the clinical effect of two different resin cements on the glass fiber-reinforced posts. Methods : One hundred and thirty-six teeth were randomly divided into two groups, with sixty-eight in each. Group A used Multilink N self-etch system and group B used RelyX Unicem self-adhesive system to bond fiber posts. Follow-up examinations took place at 6, 12 and 24 months after the placement. Results : The success ratios of two groups were all 97% above and there was no significant difference between two groups (P > 0.05). Conclusion Multilink N self-etch system and RelyX Unicem self-adhesive system all have good effect on glass fiber-reinforced posts bonding.

Implant restoration ; Provisional restoration ; Healing abutment ; Esthetic zone ; Esthetic outcomes: To compare the esthetic outcomes of peri-implant soft tissue conditioning with provisional restorations and healing abutments. Methods : A total of 48 patients missing a single tooth in the esthetic zone were chosen for the present study and divided into two groups. Twenty-six patients in Group A used provisional restorations to condition the peri-implant soft tissue before final restorations, while 22 patients in Group B used healing abutments to condition the soft tissue. All patients were evaluated by pink esthetic scores (PESs) at the time of the final restoration and at a 1-year follow-up. Results: A total of 26 implants in Group A and 22 implants in Group B showed good peri-implant soft tissue condition. PESs at the time of the final restoration and at the 1-year follow-up in Group A were 8.18 and 8.35, respectively, and 6.73 and 8.18 in Group B, respectively. PESs at the time of final restoration and at the 1-year follow-up were not significantly different in Group A but were significantly different in Group B. The PESs of the two groups were significantly different at the final restoration but were not significantly different at the 1-year follow-up. Conclusions Provisional restoration in the esthetic zone can improve the pink esthetic effect when permanent restoration.
