Objective: To evaluate the clinical efficacy of digitally guided precision crown lengthening in secondary aesthetic rehabilitation cases, and to provide a clinical reference for digitally guided crown lengthening procedures and secondary aesthetic restorations. Methods: We present a case of a patient with tetracycline-stained teeth, partial detachment of anterior resin veneers, and gingival margin discrepancies. The patient underwent digitally guided precision crown lengthening followed by secondary aesthetic rehabilitation. Multimodal data, including intraoral, facial, and CBCT scans, were integrated to construct a four-dimensional virtual patient model (incorporating teeth, face, bone, and occlusion) for surgical planning and 3D-printed guide fabrication. Secondary aesthetic restoration was performed after achieving stable post-surgical outcomes. Based on this case, we conducted a detailed analysis and reviewed relevant literature on crown lengthening in secondary aesthetic rehabilitation. Results: The gingival contour of the anterior teeth exhibited significant improvement, with enhanced symmetry and stable gingival margin positioning that closely matched the preoperative design. The crown lengthening procedure demonstrated high precision, and the final outcome was aesthetic and functional. Literature review indicated that secondary restorations frequently present challenges such as gingival contour discrepancies and inflammation. Aesthetic crown lengthening in the anterior region should optimize both soft and hard tissue morphology to meet aesthetic standards, with digital technology improving procedural accuracy. Conclusion Precision crown lengthening effectively addresses gingival margin discrepancies in secondary aesthetic rehabilitation, ensuring stable gingival positioning and superior aesthetic outcomes. This approach is particularly suitable for cases with high aesthetic demands.

Diamond-Blackfan anemia(DBA),also known as congenital pure red cell aplasia,is a rare genetic disorder characterized by bone marrow failure,congenital anomalies,and severe red blood cell abnormalities.The rarity of the condition,and consequently limited patient pool and scarcity of research models,means that the pathogenic mechanisms associated with genetic mutations in DBA remain uncertain,and the clinical treatment options are limited.This review synthesizes the findings from zebrafish,mouse,and human cellular models of DBA mutations.We clarify the pathogenic mechanisms and monitor the progression of drugs into clinical trials,thereby aiding further in-depth explorations into the etiology and therapeutic advancements for DBA.

Humanistic caring for patients in the operating room refers to providing the whole process of caring medical services for patients in the operating room.

Objective:To summarize and analyze the clinical treatment of aspergillus infection in the central nervous system.Methods:Data was obtained from a recipient who were diagnosed with invasive aspergillosis in the central nervous system after liver transplantation.We retrospectively analyzed the clinical character of the recipient." Liver transplantation" , " Aspergillus" , " brain" and " aspergillus" were searched for literature published in English or Chinese in Wanfang data, CNKI and PubMed database for nearly 5 years until January 2022.Results:A 33 years old recipient was admitted to the hospital with fatigue, chest distress and shortness of breath after liver transplantation on postoperative day(POD)48.On the computed tomography(CT)scan of the chest, multiple exudative lesions was observed in both lungs.Multiple sputum cultures were grown as Candida albicans.The symptoms of chest tightness and shortness of breath were significantly improved by treating with caspofungin compared before.On POD 79, the recipient developed stubborn nausea and vomiting.Cranial enhanced magnetic resonance imaging(MRI)showed central nervous system(CNS)infection.Numerous traditional pathogenic microorganisms tests of cerebrospinal fluid(CSF)were all negative.With the help of metagenomics next generation sequencing(mNGS), aspergillus fumigatus was detected in CSF.The recipient received therapy with voriconazole and rehabilitation.Therapy with voriconazole was continuous for 8 months.Unfortunately, the recipient developed cholestasis due to repeated biliary infection and eventually died of liver failure 13 months later.Conclusions:Although the mortality rate of aspergillus infection in the central nervous system is very high after liver transplantation, timely and effective treatment is still expected to improve its prognosis.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

Objective To explore the effects and influences of meridian stretch stocking for prevention of lower extremity deep vein thrombosis ( LEDVT ) after gynecological pelvic surgery. Methods A total of 210 patients,who conducted pelvic surgery at Department of Obstetrics and Gynecology, Wuhan Third Hospital from April 2010 to February 2013, were randomly divided into routine group (Group A), the common stretch stocking group ( Group B) and meridian stretch stocking group ( Group C) , 70 cases in each group,according to their check-in time. The patients of Group A followed routine nursing methods, and the patients of Group B complied with normal stretch stocking while the patients of Group C adopted meridian stretch stocking. The usage of stretch stockings was on the basis of conventional nursing methods and applied immediately after the surgery. Then a series of comparisons were made in terms of lower extremity venous blood flow velocity, foot dorsum skin temperature and the incidence of LEDVT, coagulation and fibrinolytic function, etc. Results Group C possessed the lowest LEDVT incidence in three groups and the differences were statistically significant (χ2 =6. 667,P<0. 05). Meanwhile Group C had the fastest posterior divisions superficial vein and popliteal fossa vein blood flow velocity with statistical significance compared with the other two groups (P<0. 01). The lower limb dorsal skin temperature of Group C was higher than that of Group A and Group B after two and four hours′ surgery ( P<0. 01). There was no statistical difference in blood coagulation and fibrinolytic function of the three groups (P>0. 05). Conclusions Meridian stretch stocking can advance venous blood flow velocity, improve lower limb dorsal skin temperature and reduce LEDVT incidence of patients with gynecological pelvic surgery.
