Attention deficit hyperactivity disorder (ADHD) is often accompanied by tic disorder. The core pathogenesis is considered to be ministerial fire scorching yin and internal stirring of deficient wind, which leads to disharmony between the body and spirit, resulting in clinical manifestations. The treatment principles emphasize nourishing yin fluids, calming ministerial fire, and extinguishing endogenous wind (内风). The method of nourishing yin fluids is applied throughout the entire treatment process, commonly using ingredients such as Shudihuang (Rehmanniae Radix Praeparata), Shanzhuyu (Corni Fructus), Gouqizi (Lycii Fructus), Wuweizi (Schisandrae Chinensis Fructus), and Tusizi (Cuscutae Semen). These are combined with approaches to harmonize the zang-fu organs, primarily including extinguishing liver wind, clearing heart fire, nourishing kidney water, and strengthening spleen earth, thereby stabilizing ministerial fire and extinguishing endogenous wind. Additionally, emotional regulation and smoothing emotional constraint are essential to improve clinical symptoms in children with ADHD comorbid with tic disorder.

Hydrogen-rich water (HRW) shows excellent antibacterial, anti-inflammatory, antioxidant, and wound-healing properties and plays a positive role in the treatment of various diseases, such as brain injury, kidney injury, and periodontitis. Current studies found that HRW can inhibit periodontopathogenic biofilm formation, inhibit oral connective tissue and bone tissue destruction, and show anti-inflammatory and antioxidant properties in periodontitis. Additionally, HRW can alleviate periodontal tissue damage by inhibiting oxidative stress and up-regulating the expression of antioxidant enzymes, such as glutathione peroxidase and superoxide dismutase. HRW exerts anti-inflammatory effects by regulating the nuclear factor erythroid 2-related factor 2 and mitogen-activated protein kinase pathways, which are closely associated with inflammation. Additionally, HRW inhibits the expression of inflammatory cytokines, such as interleukins, inhibits the growth and proliferation of bacterial plaque biofilms, and down-regulates glycosyltransferases and glucan-binding proteins to prevent bacterial adhesion and subsequent development of periodontitis. Furthermore, HRW has a positive effect on the expression of various cell growth factors, α-smooth muscle actin, and type I collagen, which promotes wound healing. Current clinical studies have demonstrated the biological safety of HRW (to a certain extent) and reported no adverse reactions. However, most studies on HRW in oral diseases are preclinical in vivo and in vitro studies. Therefore, further clinical studies are required to validate the therapeutic significance and optimal therapeutic regimen of HRW in human periodontitis. This article aims to review the therapeutic role and the underlying mechanisms of HRW in periodontitis.

Objective :
To explore the advantages of static navigation in locating calcified root canal therapy, and to provide reference for clinical diagnosis and treatment of calcified teeth.
Methods:
A case of acute periapical periodontitis of anterior teeth with full-length calcification of root canal was reported. A lingual minimally invasive approach was used as a conservative method of controlling the infection of teeth and preserving the incisors through the digital guide plate. The diagnosis and treatment of this type of case were analyzed retrospectively with reference to the literature.
Results:
One patient complained that the pain of left anterior teeth was aggravated for 2 days. After examination, he was diagnosed with acute periapical periodontitis of 21 teeth with total root canal calcification. With the assistance of static navigation, the root canal was located after 10 minutes, the calcification was dredged for 15 minutes, and the acute pain symptoms of the patient were relieved that day. After one year of follow-up, there was no discomfort in the teeth, and the range of low-density shadow in the apical film was reduced. After 3 years of follow-up, there was no discomfort in the teeth, and the low-density shadow of the apical root was further reduced by apical film examination. As shown by the results of the literature review, static navigation technology is advantageous because the success rate of dredging calcified root canals is neither associated with the operator’s treatment experience nor the use of microscope and ultrasonic equipment. Regardless of the degree of calcification, this method can significantly reduce the iatrogenic risk, but it is closely related to the accuracy and stability of the guide plate. However, this method is not suitable for calcified teeth with calcification under root canal curvature and limited operating space. Cone-beam computed tomography (CBCT) is recommended to locate calcified root canals, and the imaging quality is an important factor that affects the correct preoperative planning. When performing static navigation endodontic treatment, thermal damage can be reduced by selecting a drill with a small diameter that matches the guide ring and cooling the drill with frozen irrigation solution.
Conclusion
Static navigation-assisted treatment of calcified root canals is accurate and minimally invasive, which reduces clinical treatment time, preserves the lingual approach at the incisal ridge to further ensure the integrity of teeth, and ensures the long-term preservation of affected teeth.

OBJECTIVE To establish fingerprint, chemical pattern recognition and multi-component quantification analysis of Sanzi powder, and evaluate its quality. METHODS HPLC method was adopted. The fingerprints of 15 batches of Sanzi powder were established by using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine (2012 edition). Cluster analysis, principal component analysis and orthogonal partial least squares-discriminant analysis were also conducted. The variable importance in projection (VIP) value greater than 1 was used as the index to screen the differential markers, and the contents of the differential markers were determined by the same HPLC method. RESULTS A total of 21 common peaks in the HPLC fingerprints of 15 batches of Sanzi powder were calibrated, and the similarities of them were 0.994- 0.999; 6 common peaks were identified, including gallic acid (peak 3), garminoside (peak 10), corilagin (peak 11), chebulinic acid (peak 16), ellagic acid (peak 18), crocin Ⅰ (peak 19). According to the results of cluster analysis, YKD2024LH005,No.YKD2023LH062) principal component analysis and orthogonal partial least squares-discriminant analysis, 15 batches of samples could be clustered into two categories: S1, S5, S7, S9, S14 were clustered into one category; S2-S4, S6, S8, S10-S13, S15 were clustered into one category. VIP values of 11 differential components such as corilagin, chebulinic acid and ellagic acid were higher than 1. Among 15 batches of samples, the contents of corilagin, chebulinic acid and ellagic acid ranged 2.667-5.152, 9.506- 13.522, 0.891-1.811 mg/g. CONCLUSIONS Established HPLC fingerprint and multi-component quantification analysis of Sanzi powder are rapid and simple, and can be used for quality evaluation of Sanzi powder by combining with chemical pattern recognition. Eleven components such as corilagin, chebulinic acid and ellagic acid are differential markers affecting the quality of Sanzi powder.

Objective:
To establish a prediction model for high-risk cardiovascular disease (CVD) among residents aged 35 to 75 years, so as to provide the basis for improving CVD prevention and control measures.
Methods:
Permanent residents aged 35 to 75 years were selected from Dongcheng District, Beijing Municipality using the stratified random sampling method from 2018 to 2023. Demographic information, lifestyle, waist circumference and blood biochemical indicators were collected through questionnaire surveys, physical examinations and laboratory tests. Influencing factors for high-risk CVD among residents aged 35 to 75 years were identified using a multivariable logistic regression model, and a prediction model for high-risk CVD was established. The predictive effect was evaluated using the receiver operating characteristic (ROC) curve.
Results:
A total of 6 968 individuals were surveyed, including 2 821 males (40.49%) and 4 147 females (59.51%), and had a mean age of (59.92±9.33) years. There were 1 155 high-risk CVD population, with a detection rate of 16.58%. Multivariable logistic regression analysis showed that gender, age, smoking, central obesity, systolic blood pressure, fasting blood glucose, triglyceride and low-density lipoprotein cholesterol were influencing factors for high-risk CVD among residents aged 35 to 75 years (all P<0.05). The area under the ROC curve of the established prediction model was 0.849 (95%CI: 0.834-0.863), with a sensitivity of 0.693 and a specificity of 0.863, indicating good discrimination.
Conclusion
The model constructed by eight factors including demographic characteristics, lifestyle and blood biochemical indicators has good predictive value for high-risk CVD among residents aged 35 to 75 years.

ObjectiveTo explore the effects of angle and original moisture content on the moisture distribution, migration and contents of effective components in the drying process of sliced Salviae Miltiorrhizae Radix et Rhizoma(SMRR). MethodsSet the slicing angles of SMRR at 30°, 45°, and 90°. Cut the fresh samples, 1/3 dehydrated samples, and 2/3 dehydrated samples, dry them in an oven at 40 ℃ and take samples at the set time points. Low-field nuclear magnetic resonance(LF-NMR) and magnetic resonance imaging(MRI) were used to analyze the changes in transverse relaxation time(T2) of SMRR samples in 9 treatment groups at specific times, as well as the distribution and migration of water in the samples. The contents of tanshinone ⅡA, tanshinone Ⅰ, cryptotanshinone, and salvianolic acid B in samples from 9 different treatment groups were determined by high performance liquid chromatography(HPLC), and the best processing technology of SMRR was screened by combining with One-way ANOVA, Duncan multiple comparison and principal component analysis(PCA). ResultsThe moisture content of dry basis of SMRR in each treatment group decreased with the extension of drying time. The drying rate of fresh cut group decreased slowly at first, while the drying rate of water loss group showed a trend of increasing at first and then decreasing. The internal water of SMRR could be divided into three states, including bound water, non flowing water and free water. During the drying process, the water migration law showed that the free water of fresh cut group disappeared after drying for 12 h, the content of bound water gradually decreased, and the overall fluidity deteriorated. In the water loss group, part of the free water was transformed into more cohesive and non flowing water after drying for 3 h, and the three kinds of water basically disappeared after drying for 12 h. The MRI results showed that the entire dehydration process slowly moved from the outer side to the center, and the internal water eventually dissipated. In terms of the contents of active ingredients, the order of the effect of slicing angle on the total content of active ingredients in SMRR was 30°>45°>90°. The content of tanshinones was ranked as 1/3 dehydrated group>2/3 dehydrated group>fresh cut group, and the content of salvianolic acid B was ranked as 1/3 dehydrated group>fresh cut group>2/3 dehydrated group. Combined with the results of PCA and comprehensive scoring results, the overall level of effective component content in SMRR was the highest when cut at 30° after 1/3 of water loss. ConclusionAfter comprehensive evaluation, SMRR can be sliced at 30° after 1/3 of water loss. It is not only easy to cut, but also the surface and cross-sectional colors remain basically unchanged after drying, which is similar to the color under traditional processing, and the effective ingredients are preserved the highest. This study can provide a basis for the optimization of processing technology of SMRR.

Objective:To analyze the current status of red blood cell transfusion in very preterm infants (VPI) (gestational age at birth <32 weeks) from Chinese Neonatal Network (CHNN) in 2022.Methods:This cross-sectional study was based on the CHNN VPI cohort. It included 6 985 VPI admitted to CHNN 89 participating centers within 24 hours after birth in 2022. VPI with major congenital anomalies or those transferred to non-CHNN centers for treatment or discharged against medical advice were excluded. VPI were categorized based on whether they received red blood cell transfusions, their gestational age at birth, the type of respiratory support received during transfusion, and whether the pre-transfusion hemoglobin levels exceeded the thresholds. General characteristics, red blood cell transfusion rates, number of transfusions, timing of the first transfusion, and pre-transfusion hemoglobin levels were compared among different groups. The incidence of adverse outcomes between the group of VPI who received transfusions above the threshold and those who received transfusions below the threshold were compared. Comparison among different groups was conducted using χ2 tests, Kruskal-Wallis H tests, Mann-Whitney U test, and so on. Trends by gestational age at birth were evaluated by Cochran-Armitage tests and Jonckheere-Terpstra tests for trend. Results:Among the 6 985 VPI, 3 865 cases(55.3%) were male, with a gestational age at birth of 30.0 (28.6, 31.0) weeks and a birth weight of (1 302±321) g. Overall, 3 617 cases (51.8%) received red blood cell transfusion, while 3 368 cases (48.2%) did not. The red blood cell transfusion rate was 51.8% (3 617/6 985), with rates of 77.7% (893/1 150) for those born before 28 weeks gestational age and 46.7% (2 724/5 835) for those born between 28 and 31 weeks gestational age. A total of 9 616 times red blood cell transfusions were administered to 3 617 VPI, with 632 times missing pre-transfusion hemoglobin data, and 8 984 times included in the analysis. Of the red blood cell transfusions, 25.6% (2 459/9 616) were administered when invasive respiratory support was required, 51.3% (4 934/9 616) were receiving non-invasive respiratory support, while 23.1% (2 223/9, 616) were given when no respiratory support was needed. Compared to the non-transfusion group, the red blood cell transfusion group had a higher rate of pregnancy-induced hypertension in mothers, lower rates of born via cesarean section and mother′s antenatal steroid administration, smaller gestational age, lower birth weight, a higher proportion of small-for-gestational-age, multiple births, and proportions of Apgar score at the 5 th minute after birth ≤3 (all P<0.05). They were also less likely to be female, born in hospital or undergo delayed cord clamping (all P<0.01). Additionally, higher transport risk index of physiologic stability score at admission were observed in the red blood cell transfusion group ( P<0.001). The number of red blood cell transfusion was 2 (1, 3) times, with the first transfusion occurring at an age of 18 (8, 29) days, and a pre-transfusion hemoglobin level of 97 (86, 109) g/L. For VPI ≤7 days of age, the pre-transfusion hemoglobin levels for invasive respiratory support, non-invasive respiratory support, or no respiratory support, respectively, with no statistically significant differences between groups ( H=5.59, P=0.061). For VPI aged 8 to 21 days and≥22 days, the levels with statistically differences between groups (both P<0.01). Red blood cell transfusions above recommended thresholds were observed in all respiratory support categories at different stages of life, with the highest prevalence in infants aged 8 to 21 days and≥22 days who did not require respiratory support, at 90.1% (264/273) and 91.1%(1 578/1 732), respectively. The rate of necrotizing enterocolitis was higher in the above-threshold group ( χ2=10.59, P=0.001), and the duration of hospital stay was longer in the above-threshold group ( Z=4.67, P<0.001) compared to the below-threshold group. Conclusions:In 2022, the red blood cell transfusion rate was relatively high among VPI from CHNN. Pre-transfusion hemoglobin levels frequently exceeded recommended transfusion thresholds.

BACKGROUND:In recent years,numerous studies have shown that autophagy and mitophagy play an important role in the regulation of bone metabolism.Under non-physiological conditions,mitophagy breaks the balance of bone metabolism and triggers metabolism disorders,which affect osteoblasts,osteoclasts,osteocytes,chondrocytes,bone marrow mesenchymal stem cells,etc. OBJECTIVE:To summarize the mechanism of mitophagy in regulating bone metabolic diseases and its application in clinical treatment. METHODS:PubMed,Web of Science,CNKI,WanFang and VIP databases were searched by computer using the keywords of"mitophagy,bone metabolism,osteoblasts,osteoclasts,osteocytes,chondrocytes,bone marrow mesenchymal stem cells"in English and Chinese.The search time was from 2008 to 2023.According to the inclusion criteria,90 articles were finally included for review and analysis. RESULTS AND CONCLUSION:Mitophagy promotes the generation of osteoblasts through SIRT1,PINK1/Parkin,FOXO3 and PI3K signaling pathways,while inhibiting osteoclast function through PINK1/Parkin and SIRT1 signaling pathways.Mitophagy leads to bone loss by increasing calcium phosphate particles and tissue protein kinase K in bone tissue.Mitophagy improves the function of chondrocytes through PINK1/Parkin,PI3K/AKT/mTOR and AMPK signaling pathways.Modulation of mitophagy shows great potential in the treatment of bone diseases,but there are still some issues to be further explored,such as different stages of drug-activated mitophagy,and the regulatory mechanisms of different signaling pathways.

Objective:
Miniscrews are commonly utilized as temporary anchorage devices (TADs) in cases of maxillary protrusion and premolar extraction. This study aimed to investigate the effects and potential side effects of two conventional miniscrew configurations on the maxillary incisors.
Methods:
Eighty-two adult patients with maxillary dentoalveolar protrusion who had undergone bilateral first premolar extraction were retrospectively divided into three groups: non-TAD, two posterior miniscrews only (P-TADs), and two anterior and two posterior miniscrews combined (AP-TADs). Cone-beam computed tomography was used to evaluate the maxillary central incisors (U1).
Results:
The APTADs group had significantly greater U1 intrusion (1.99 ± 2.37 mm, n = 50) and less retroclination (1.70° ± 8.80°) compared to the P-TADs (–0.07 ± 1.65 mm and 9.45° ± 10.68°, n = 60) and non-TAD group (0.30 ± 1.61 mm and 1.91° ± 9.39°, n = 54).However, the AP-TADs group suffered from significantly greater apical root resorption (ARR) of U1 (2.69 ± 1.38 mm) than the P-TADs (1.63 ± 1.46 mm) and non-TAD group (0.89 ± 0.97 mm). Notably, the incidence of grade IV ARR was 16.6% in the AP-TADs group, significantly higher than the rates observed in the P-TADs (6.7%) and non-TAD (1.9%) groups. Multiple regression analysis revealed that after excluding tooth movement factors, the AP-TADs configuration resulted in an additional 0.5 mm of ARR compared with the P-TADs group.
Conclusions
In cases of maxillary protrusion and premolar extraction, the use of combined anterior and posterior miniscrews enhances incisor intrusion and minimizes torque loss of the maxillary incisors. However, this approach results in more severe ARR, likely due to the increased apical movement and composite force exerted.
