The biological samples of oral genetic diseases and rare diseases are extremely precious. Collecting and preserving these biological samples are helpful to elucidate the mechanisms and improve the level of diagnose and treatment of oral genetic diseases and rare diseases. The standardized construction of biobanks for oral genetic diseases and rare diseases is important for achieving these goals. At present, there is very little information on the construction of these biobanks, and the standards or suggestions for the classification and coding of biological samples from oral and maxillofacial sources, and this is not conducive to the standardization and information construction of biobanks for special oral diseases. This consensus summarizes the background, necessity, principles, and key points of constructing the biobank for oral genetic diseases and rare diseases. On the base of the group standard "Classification and Coding for Human Biomaterial" (GB/T 39768-2021) issued by the National Technical Committee for Standardization of Biological Samples, we suggest 76 new coding numbers for different of biological samples from oral and maxillofacial sources. We hope the consensus may promote the standardization, and smartization on the biobank construction as well as the overall research level of oral genetic diseases and rare diseases in China.

Objective:To establish the quality evaluation method of Prunellae spica dispensing granules based on three quality indexes of standard decoction. Methods:Fourteen batches of Prunellae spica were collected from different habitats. According to technical requirements, fourteen batches of Prunellae spica standard decoction and three batches of formula granules were prepared and the paste-forming rates were calculated. The fingerprints of Prunellae spica standard decoction and formula granules were established by Ultra High Performance Liquid Chromatography (UPLC). The similarity values of fingerprints between dispensing granules and standard decoction were calculated. The content and transferring rate of Rosmarinic acid were determined and calculated. Results:The average paste-forming rate of Prunellae spica was (12.59±2.32)%. The paste-forming rates of the three batches were 11.14%, 10.78% and 10.39% respectively. The average content of Rosmarinic acid in standard decoction was (18.99±9.74)mg/g. The average transferring rate was (60.58±7.87)%. The contents of three batches were 7.40 mg/g, 7.49 mg/g and 7.09 mg/g. The transferring rates were 52.06%, 50.10% and 50.40% respectively. Nine common fingerprint peaks were identified in the fingerprints of standard decoction and formula granules, two of which were identified as Rosmarinic acid and Caffeic acid by comparison of reference substance. The fingerprints similarity of Prunellae spica dispensing granules and standard decoction were 0.954, 0.973 and 0.952, respectively. Conclusions:The quality indexes of three batches of formulation granules are consistent with standard decoction. This method could provide reference for the establishment of quality standard of Prunellae spica dispensing granules.

METHODS Retrieved from the Cochrane Library ,PubMed,Embase,CNKI,Wanfang database,CBM and HTA official website ,systematic review/meta -analysis,pharmacoeconomics research and HTA reports about calcitonin in the treatment of PMOP were retrieved from the inception to Sept . 30th,2022. Two researchers independently carried out screening ,data extraction and quality evaluation ,and analyzed the data results descriptively . RESULTS A total of 18 studies were included ,including 12 SR/meta-analysis and 6 economic studies ,and no HTA report was retrieved . In terms of effectiveness , the results of the included studies were basically consistent :calcitonin had a certain advantage in reducing the incidence of vertebral fracture compared with calcium and lasoxifene alone ,but did not show clinical advantage compared with other positive drugs . In terms of reducing the incidence of non -vertebral fractures , calcitonin had some advantages ,compared with calcium al one and raloxifene ,but did not show clinical advantage compared with other positive drugs . In terms of improving bone mineral density(BMD),only 2 studies showed that calcitonin had a certain advantage over calcium but no advantage was observed compared with other positive drugs . In terms of improving non - vertebral BMD ,only 1 study showed that calcitonin combined with calcium had certain advantages compared with calcium alone in improving femoral BMD ,but there was no advantage compared with other positive drugs . In terms of lowering bone pain scores , both included studies demonstrated short -term benefit of nasal calcitonin in reducing acute pain was found in patients with vertebral fractures,but not in patients with chronic pain . In terms of safety ,the three included studies showed that calcitonin caused mild adverse reactions compared with other positive drugs ,but there was a risk of malignant tumors after long -term use . In terms of economy,only 1 study showed the use of nasal calcitonin in the treatment of PMOP had more economic advantages than no treatment or etidronate . CONCLUSIONS Calcitonin has a certain effect on reducing acute pain in patients with PMOP vertebral fracture,and its safety needs further investigation . No obvious economic advantage has been found .

The Brodmann area(BA)-based map is one of the most widely used cortical maps for studies of human brain functions and in clinical practice;however,the molecular architecture of BAs remains unknown.The present study provided a global multiregional proteomic map of the human cerebral cortex by analyzing 29 BAs.These 29 BAs were grouped into 6 clusters based on similarities in proteomic patterns:the motor and sensory cluster,vision cluster,auditory and Broca's area cluster,Wernicke's area cluster,cingulate cortex cluster,and heterogeneous function cluster.We identified 474 cluster-specific and 134 BA-specific signature proteins whose functions are closely associated with specialized functions and disease vulnerability of the corresponding clus-ter or BA.The findings of the present study could provide explanations for the functional connec-tions between the anterior cingulate cortex and sensorimotor cortex and for anxiety-related function in the sensorimotor cortex.The brain transcriptome and proteome comparison indicates that they both could reflect the function of cerebral cortex,but show different characteristics.These pro-teomic data are publicly available at the Human Brain Proteome Atlas(www.brain-omics.com).Our results may enhance our understanding of the molecular basis of brain functions and provide an important resource to support human brain research.

Objective:To explore the diagnostic process and outcomes of patients with aplastic anemia (AA) who received outpatient treatment in a real-world setting.Methods:The diagnostic processes, treatment regimens, and outcomes of 176 patients with AA treated in outpatient centers from January 2018 to December 2019 were reviewed.Results:The median interval from the onset of symptoms to the first visit was 7 (5-120) months. Complaints during the first visit included bleeding (52.3% ) , anemia (51.7% ) , and infection (6.8% ) . For diagnosis, 168 patients (95.5% ) underwent bone marrow aspiration; however, only 22 of them (17.1% ) consented aspiration in multiple sites (sternum) . The completion rate of bone marrow biopsy was 85.1% (143/168) ; flow immunophenotype and karyotype analyses were performed on 59.5% (100/168) and 58.9% (99/168) of AA patients, respectively, and the culture of clonal forming units by bone marrow mononuclear cells was performed on 26.8% (45/168) of AA patients. The most preferred regimen was cyclosporine combined with androgen and levamisole (43.8% , 77 patients) , followed by cyclosporine combined with androgen (25.6% , 45 patients) . Cyclosporine alone was administered in 24 patients (13.6% ) and androgen alone in 16 patients (9.1% ) . Furthermore, 14 patients (7.9% ) did not consent to any drugs or only chose traditional Chinese medicine. The patients were divided according to the frequencies of follow-up: regular follow-up group (≥4 times/year, n=130) and irregular group (<4 times/year, n=46) . The former had a higher 6-month remission rate (52.5% vs 28.0% , P=0.005) , a greater high-quality remission rate in 12 months (40.7% vs 16.7% , P=0.027) , and a lower relapse rate in 24 months (4.4% vs 36.4% , P=0.001) . Conclusion:In real-world settings, bone marrow aspiration in multiple sites should be addressed in outpatient treatment for AA diagnostic work-up, including PNH clone screening, flow immunophenotype, chromosome karyotype analysis, and culture of clonal forming units. Patients with AA who follow regular visits were more likely to achieve high-quality remission and a lower relapse rate. Visits at least four times per year are recommended for AA patients undergoing outpatient treatment.

Objective:To explore the efficacy and safety of ibrutinib treatment for relapsed/refractory (R/R) primary autoimmune hemolytic anemia (AIHA) .Methods:Two cases of primary AIHA with relapse events were refractory to glucocorticoid, anti-CD20 monoclonal antibody, immunosuppressive drugs, and splenectomy (case 1 only) . Ibrutinib treatment was administered at an initial dose of 280 mg/d (420 mg/d for case 1 from the 3rd to 8th week) .Results:Both patients achieved transfusion independence and HGB>20 g/L above baseline after 2 weeks (partial response) . For case 1, HGB concentration restored to 113 g/L but with incomplete hemolysis recovery after 10 weeks; HGB reached the level of 118 g/L, also with incomplete hemolysis recovery, after 6 weeks in case 2. They all acquired complete response with incomplete hemolysis recovery (CRi) . The responses sustained 14 weeks and 10 weeks after follow-up at 16 weeks and 12 weeks, respectively. During the treatment, hematologic and nonhematologic toxicity is mild and acceptable.Conclusion:Ibrutinib alone is effective for the 2 R/R primary AIHA cases. We need further clinical trial to identify its efficacy and safety.
