Patients with periodontal disease often require combined periodontal-orthodontic interventions to restore periodontal health, function, and aesthetics, ensuring both patient satisfaction and long-term stability. Managing these patients involving orthodontic tooth movement can be particularly challenging due to compromised periodontal soft and hard tissues, especially in severe cases. Therefore, close collaboration between orthodontists and periodontists for comprehensive diagnosis and sequential treatment, along with diligent patient compliance throughout the entire process, is crucial for achieving favorable treatment outcomes. Moreover, long-term orthodontic retention and periodontal follow-up are essential to sustain treatment success. This expert consensus, informed by the latest clinical research and practical experience, addresses clinical considerations for orthodontic treatment of periodontal patients, delineating indications, objectives, procedures, and principles with the aim of providing clear and practical guidance for clinical practitioners.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Endo-periodontal lesions(EPLs)involve both the periodontium and pulp tissue and have complicated etiologies and pathogenic mechanisms,including unique anatomical and microbiological characteristics and multiple contributing factors.This etiological complexity leads to difficulties in determining patient prognosis,posing great challenges in clinical practice.Furthermore,EPL-affected teeth require multidisciplinary therapy,including periodontal therapy,endodontic therapy and others,but there is still much debate about the appropriate timing of periodontal therapy and root canal therapy.By compiling the most recent findings on the etiology,pathogenesis,clinical characteristics,diagnosis,therapy,and prognosis of EPL-affected teeth,this consensus sought to support clinicians in making the best possible treatment decisions based on both biological and clinical evidence.

【Objective】 To evaluate the application of computer-aided personal interviewing (CAPI) and computer-assisted telephone interview (CATI) in the satisfaction survey among blood donors. 【Methods】 Voluntary blood donors from stationary and mobile blood collecting sites of Zhejiang Blood Center from Jan 2018 to Dec 2020 were surveyed according to the principle of random sampling. The satisfactory degree of totally 21 items involving pre-donation, in-donation, and post-donation were surveyed. The outcomes were categorized and subsequently analyzed by SPSS23.0, and the differences in demography and blood types between different years were analyzed. 【Results】 5 534 voluntary blood donors were investigated via CAPI and CATI, which contributed to the reflection of real needs of blood donors. The results showed that the comprehensive satisfactory degree of blood donors increased from 95.4% in 2018 to 95.8% in 2020. Significant difference has been found in the eight indexes in Zhejiang (P<0.05) as blood donation publicity, environment of blood donation, service and professional skills of healthcare physicians, skills of phlebotomist before donation, service of pre-donation testing physicians, service and skills of phlebotomist during donation. 【Conclusion】 The combination of CAPI and CATI methods used in the survey of blood donor satisfactory degree, which has presented credible results, is more objective, convenient and time saving, therefore worth popularizing.

Objective To observe the prevalence and related risk factors of arterial stiffness measured by brachial-ankle pulse wave velocity (baPWV) in patients with systemic lupus erythematosus (SLE).Methods The study population included 135 patients currently enrolled in the Chinese SLE Treatment and Research group registry (CSTAR).All traditional cardiovascular risk factors and SLE-related disease factors were collected on the day of the baPWV examination.Results (1) Significant differences were observed in age (P ＜ 0.000),family history of cardiovascular disease (P =0.003),mean blood pressure (P =0.000) and hemoglobin A1c (P =0.023) between SLE patients with normal and abnormal arterial stiffness.In addition,SLE patients with abnormal arterial stiffness had lower creatinine clearance rates [85.9(65.5-108.8) ml/min vs.106.4 (86.8-124.6) ml/min,P =0.011],longer disease and hydroxychloroquine duration (P =0.002 and P =0.022,respectively),and higher proportion of intravenous cyclophosphamide use (OR =3.04,95％ CI:1.230-7.514,P =0.013) as compared to patients with normal arterial stiffness.(2) After adjustment of all confounding factors,age (OR =4.56,95％ CI:1.863-11.133,P =0.001),mean blood pressure (OR =1.12,95％ CI:1.055-1.196,P =0.000),disease duration (OR =1.12,95％ CI:1.050-1.367,P =0.007) and the proportion of intravenous cyclophosphamide use (OR =2.86,95％ CI:1.364-5.979,P =0.005) remained as independent risk factors for abnormal arterial stiffness in SLE patients.Conclusion Both traditional cardiovascular risk factors and SLE-related factors are associated with the risk of increased arterial stiffness.

From September 2002 to May 2006, five patients ( age range, 24 to 46; mean, 32) with tibial defect underwent transplantation of free latissmus dorsi osteocutaneous flap using bridge-like vascular anastomosis. All the osteocutaneous flaps survived without any serious complications, and tibial defects were improved completely. After 1.5 to 4.5 years' follow-up ( mean, 2.6), no remarkable dysfunction was found at donor sites, and local injury was reduced. This study indicates that transplantation of free latissmus dorsi osteocutaneous flap using bridge-like vascular anastomosis might be useful in leg reconstructive surgery if only one vessel is remained.

Objective To summarize clinical experience in application of nail-bed lengthening operation for fingertip injuries.Methods From September 2003 to May 2007,36 patients (25 men and 11 women) aged 16 -45 years (26 in average) with nail defect by fingertip injuries underwent reconstruction operation using nail-bed lengthening at Orthopaedics and Traumatology Hospital of Taizhou,with the thumb involved in 15 cases,the index finger in 10 cases,the middle finger in eight eases and the ring finger in three case.A skin rectangle with thickness of 2 - 3 mm and width as that of the nail was resected at the skin edge 5 -6 mm distant from the epenychium,without damage to underlying subcutaneous vascular network, and U-shape skin flap was delicately slid proximally with its ends sutured.Results All surgical operations for nail lengthening were uneventful and clinically satisfactory,and the appearance of the thumb or other fingers was good during follow-up for six months to three years (19 months in average).Conclusions Nail lengthening for fingertip injuries with nail defect is a simple and effective surgical operation which could improve the appearance of the thumb and other fingers.

The article presents a method improvement of the medial plantar pedicled flap transplantation to cover the defect of the foot heel.Since 2002,6 patients with soft tissue defects on the foot heel underwent reconstruction with the medial plantar pedicled flap transplantation of excluding the plantar fascia and 3 patients used conventional flap of the medial plantar pedicled flap transplantation.They ranged in age from 18 to 52 years(mean,32 years).All the flaps had survived completely without major complication with satisfactory clinical results.Follow-up period ranged from 1.5 to 6 years(mean,3.8years)postoperatively.There was no remarkable donor site morbidity.Patients with flap of excluding the plantar fascia had good appearance in recipient site.Injury to donor site was reduced.Skin of the instep area can be raised as an island fasciocutaneous flap based on medial plantar vessels,with the branch of medial plantar nerve supplying the instep skin to provide the sensation.The flap is thin and suitable for repairment of soft tissue defect on the foot heel.
