BACKGROUND:With the development and progress in the field of stomatology,oral implant technology has gradually become the mainstream alternative to traditional dentures.In recent years,the maturity of various bone increment techniques and the continuous development of the oral digital field have expanded the indications of dental implantation,and the success rate of implantation surgery is also increasing.However,it has become a difficult problem for some clinicians to use cone-beam computed tomography(CBCT)to accurately measure the residual alveolar ridge bone mass before implantation and to make a suitable implantation plan. OBJECTIVE:To measure the residual alveolar ridge bone mass in the proposed implant area of the mandibular first molar using the CBCT. METHODS:In a retrospective study design,the CBCT images of 205 patients with mandibular first molar loss were included to measure the height and width of the residual alveolar ridge in the proposed implant area of the mandibular first molar.The residual alveolar ridges were divided into four categories:Ⅰ,Ⅱ,Ⅲ and Ⅳ(Class Ⅱ,Ⅲ,and Ⅳ residual alveolar ridge defined as insufficient bone).Statistical analyses were conducted in terms of frequency distribution of residual alveolar ridge height,width,and morphology of the mandibular first molar,differences in residual alveolar ridge height and alveolar ridge crest width of the mandibular first molar in patients of different sexes,correlation of the residual alveolar ridge height with the crest width and bottom width of the residual alveolar ridge,as well as correlation of age with the width and height of the residual alveolar ridge crest. RESULTS AND CONCLUSION:(1)The average height of the residual alveolar ridge in the proposed implant area of the mandibular first molar was(12.14±2.96)mm,of which 43.41％(89/205)were less than 12 mm.The average width of the residual alveolar ridge in the proposed implant area of the mandibular first molar was(6.80±1.65)mm,of which 26.34％(54/205)were less than 6 mm.(2)The height of the residual alveolar ridge of the mandibular first molar was higher in males than in females,with no significant difference(P>0.05),and the width of the residual alveolar ridge of the mandibular first molar was significantly wider in males than in females(P<0.01).(3)The height of the residual alveolar ridge was negatively correlated with the top and bottom width of the residual alveolar ridge(P<0.01).Age showed a positive correlation with the residual alveolar ridge width(P<0.05)and no significant correlation with the residual alveolar ridge height(P>0.05).(4)The residual alveolar ridge of class Ⅰ accounted for 58.05％(119/205),class Ⅱ accounted for 9.27％(19/205),class Ⅲ accounted for 20.49％(42/205),and class Ⅳ accounted for 12.19％(25/205),most of which were class Ⅲ with insufficient remaining alveolar ridge bone mass.Clinicians need to individualize and design the optimal implantation plan based on the type of residual alveolar ridge.

This study aimed to localize the workplace readiness questionnaire (WRQ) and validate its applicability for assessing readiness for implementation of evidence-based practices (EBP) in primary care settings in China. The localization of the instrument will provide a practical instrument for assessing organizational readiness for change (ORC).

Objective To observe the clinical efficacy and adverse drug reactions of recombinant human growth hormone on dwarfism in children with primary nephrotic syndrome.Methods Children with dwarfism in primary nephrotic syndrome were divided into control group and treatment group.Patients in control group were orally administered prednisone acetate tablets,with an initial dose of 2 mg·kg-1·d-1,at once,no more than 60 mg in a single day,and after a duration of 6 weeks of full dosage,the dosage was reduced by 2.5 mg every 2 weeks until the maintenance dose of 5-10 mg·d-1 was administered for 12 months.Patients in treatment group were injected subcutaneously with recombinant human growth hormone 0.15 U·kg-1 at 0.5 h before bedtime every night on the basis of control group for a period of 12 months.The levels of height,bone age,standard deviation fraction of height(HtSDS),insulin-like serum growth factor 1(IGF-1),insulin-like growth factor binding protein 3(IGFBP-3),and the incidence of adverse drug reactions were compared between the two groups.Results There were 63 cases in control group and 63 cases in treatment group.The height of the children in treatment group and control group after treatment were(146.48±6.76)and(138.62±4.95)cm;the HtSDS values were-1.72±0.18 and-1.97±0.20;the IGF-1 values were(158.86±18.24)and(113.14±15.88)ng·mL-1;IGFBP-3 values were(5.21±0.83)and(3.13±0.71)μg·mL-1,the differences were all statistically significant(all P＜0.05).The incidence of adverse drug reaction in treatment group and control group were 9.52％(6 cases/63 cases)and 3.17％(2 cases/63 cases),with no statistically significant difference(P＞0.05).Conclusion Recombinant human growth hormone has a definite clinical efficacy,high safety,and effective promotion of growth and development in the treatment of primary nephrotic syndrome in children with dwarfism.

Objective:To describe the epidemiological distribution of hemorrhoids in a physical exami-nation population in China,which could provide evidence for precision prevention and early intervention of hemorrhoids.Methods:Chinese subjects over 18 years of age who underwent a physical examination in a nationwide chain of physical examination centers in 2018 were studied in a cross-sectional design,which collected information by a questionnaire and physical examination results from each subject.The epidemiological distribution of hemorrhoids was described using Logistic models.The gender-,age-,and region-detection rates of hemorrhoids were standardized to the Sixth National Population Census of the People's Republic of China(2010).Results:A total of 2 940 295 adult subjects were included in the study,of whom the average age was(41.7±14.0)years,and 52.6％were females.The standardized detection rate of hemorrhoids was higher for females(43.7％)than that for males(17.7％;P＜0.001)in this study.In the females,the age distribution of hemorrhoids was inverted U-shaped,with the highest standardized detection rate of hemorrhoids in the age group of 30-39 years(63.5％).In the males,the standardized detection rate of hemorrhoids increased along with age,with the highest percentage of 17.2％in the age group of 50-59 years,and the standardized detection rate of hemorrhoids in the age group of 60 and above decreased slightly(P＜0.001 for trend test).The participants with hypertension had a higher standardized detection rate of hemorrhoids than those with normal blood pressure in both males and females(P＜0.001).The standardized detection rate of hemorrhoids showed a positive corre-lation with body mass index(P＜0.001 for trend test in males).Conclusion:The detection rate of hemorrhoids varied to gender,age,obesity,and hypertension status,which could help to identify the risk factors and the high-risk sub-groups,and hence to strengthen health education and early detection accordingly,which could eventually reduce the incidence of hemorrhoids and improve the quality of life and health in the Chinese population.This study was conducted in a physical examination population,and the conclusions of this study should be extrapolated with caution.

Objective:To evaluate the long-term efficacy of percutaneous microwave ablation (MWA) therapy for hepatocellular carcinoma.Methods:2054 cases with Barcelona Clinic Liver Cancer (BCLC) stage 0~B at the Fifth Medical Center of the Chinese People's Liberation Army General Hospital from January 2006 to September 2020 were retrospectively collected. All patients were followed up for at least 2 years. The primary endpoint of overall survival and secondary endpoints (tumor-related survival, disease-free survival, and postoperative complications) of patients treated with ultrasound-guided percutaneous MWA were analyzed. Kaplan-Meier method was used for stratified survival rate analysis. Fine-and-Gray competing risk model was used to analyze overall survival.Results:A total of 5 503 HCC nodules [mean tumor diameter (2.6±1.6) cm] underwent 3 908 MWAs between January 2006 and September 2020, with a median follow-up time of 45.6 (24.0 -79.2) months.The technical effectiveness rate of 5 375 tumor nodules was 97.5%. The overall survival rates at 5, 10, and 15-years were 61.6%, 38.8%, and 27.0%, respectively. The tumor-specific survival rates were 67.1%, 47.2%, and 37.7%, respectively. The free tumor survival rates were 25.8%, 15.7%, and 9.9%, respectively. The incidence rate of severe complications was 2.8% (108/3 908). Further analysis showed that the technical effectiveness and survival rate over the passing three time periods from January 2006-2010, 2011-2015, and 2016-September 2020 were significantly increased, with P ?

In the field of healthcare service, it is crucial to optimize medical innovation services by combining the preferences of health service providers and demanders (i.e., stakeholders). The best-worst scaling (BWS) method is a recently developed stated preference method for assessing preferences with distinctive advantages. Nevertheless, there is a lack of a comprehensive introduction to stakeholder preference assessment using BWS, thus constraining its applications and promotion. This paper introduces the process of using BWS to assess service providers' preferences for the Shared Medical Appointment for diabetes (SMART), an integrated healthcare service of medicine and health management, in the hope of providing reference for researchers for promoting the use of BWS in implementation research.

Fermented Chinese medicine has long been used. Amid the advance for preservation of experience, the connotation of fermented Chinese medicine has been enriched and improved. However, fermented Chinese medicine prescriptions generally contain a lot of medicinals. The fermentation process is complicated and the conventional fermentation conditions fail to be strictly controlled. In addition, the judgment of the fermentation end point is highly subjective. As a result, quality of fermented Chinese medicine is of great difference among regions and unstable. At the moment, the quality standards of fermented Chinese medicine are generally outdated and different among regions, with simple quality control methods and lacking objective safe fermentation-specific evaluation indictors. It is difficult to comprehensively evaluate and control the quality of fermented medicine. These problems have aroused concern in the industry and also affected the clinical application of fermented Chinese medicine. This article summarized and analyzed the application, quality standards, and the modernization of fermentation technology and quality control methods of fermented Chinese medicine and proposed suggestions for improving the quality standards of the medicine, with a view to improving the overall quality of it.

Objective:To explore the relation of plasma Elabela with 3-month prognoses in large vessel occlusion-acute ischemic stroke (LVO-AIS) patients accepted endovascular thrombectomy (EVT).Methods:A prospective study was performed; 94 LVO-AIS patients aceepted EVT in Department of Neurology, Anhui Provincal Hospital, Anhui Medical University from August 2020 to August 2022 were selected. Plasma Elabela was detected before EVT, and 24 and 72 h after EVT. Modified Rankin scale (mRS) was used to evaluate the prognoses of the patients 3 months after EVT; differences in clinical data and plasma Elabela level between the good prognosis group and poor prognosis group were compared. Independent influencing factors for prognoses of LVO-AIS patients 3 months after EVT were analyzed by multivariate Logistic regression. Receiver operating characteristic (ROC) curve was used to analyze the efficacy of Elabela in predicting prognoses of patients with LVO-AIS 3 months after EVT.Results:Compared with the poor prognosis group, the good prognosis group had significantly lower percentages of patients with stroke history and diabetes, and lower NIHSS scores at admission ( P<0.05). Elabela level in the good prognosis group was significantly higher than that in the poor prognosis group 72 h after EVT ( P<0.05). Multivariate Logistic regression analysis showed that stroke history ( OR=0.148, P=0.037, 95% CI: 0.025-0.889), diabetes mellitus ( OR=0.148, P=0.037, 95% CI: 0.025-0.889), hypertension history ( OR=3.488, P=0.024, 95% CI: 1.177-10.339), and Elabela level 72 h after EVT ( OR=1.064, P=0.005, 95% CI: 1.019-1.111) were independent influencing factors for prognoses of LVO-AIS patients 3 months after EVT. ROC curve showed that area under ROC curve of plasma Elabela level 72 h after EVT in predicting prognosies of LVO-AIS patients 3 months after surgery was 0.718 ( P<0.001, 95% CI: 0.614-0.822). Conclusion:Plasma Elabela level 72 h after EVT may be a potential prognostic biomarker for LVO-AIS patients after EVT.

Dental and craniofacial bone development is a highly coordinated process that is tightly controlled by genetics and influenced by complex environments. The abnormal regulation of many development-related signaling molecules may lead to abnormal tooth development, severe craniofacial bone formation disorders, and developmental deformities. Transforming growth factor-β (TGF-β) is widely expressed in vivo and participates in many cellular biological processes, showing complex regulatory roles in mammalian craniofacial bone growth and tooth development. In tooth development, abnormal TGF-β signaling can lead to the failure of tooth germ formation, and its deletion mutation can directly affect odontoblast differentiation and enamel formation defects. However, the current research on TGF-β mainly focuses on the early stage of tooth development, and a comprehensive and systematic study of TGF-β-related tooth development is lacking. TGF-β signal transduction mainly controls the development of teeth and craniofacial bone by regulating the expression of development-related molecules via the classical Smad-dependent signaling pathway. In addition, the nonclassical mitogen-activated protein kinase (MAPK) pathway also participates in this process. Abnormal TGF-β signaling may cause jaw development disorders, temporomandibular joint dysplasia and inflammation, and cleft palate. Because the specific regulatory mechanism of TGF-β in craniofacial bone development has not been fully elucidated, its specific application in the treatment of related diseases is also greatly limited. This paper describes the new research progress of TGF-β in the development of teeth, jaws, temporomandibular joints and palate as well as related diseases.
