ABSTRACT
Objective To analyze the influencing factors of unplanned extubation(UE)occurrence of peripherally inserted central catheter(PICC)in the patients with hematological diseases.Methods A retro-spective cohort study method was adopted.The data of 7 298 patients with hematological diseases implanted with PICC catheter and followed up to its removal from January 1,2016 to December 31,2020 in the Hematol-ogy Hospital of Chinese Academy of Medical Sciences were collected,including the demographic information,catheterization records,maintenance and extubation records.According to whether UE occurring,they were divided into the UE group(n=262)and normal extubation group(n=7 036).The general data were com-pared between the two groups.The COX regression was used to analyze the influencing factors of UE in pa-tients with hematological diseases.The dose-effect relationship between age and PICC UE occurrence risk was studied by the restrictive cubic spline method.Results The incidence rate of UE was 3.6％(262/7 298).The COX regression analysis results showed that the gender,disease diagnosis,fibrinogen,prothrombin time,PLT,catheter material,number of punctures during catheterization,positioning method of catheter tip,num-ber of catheter-related complications occurrence were related to PICC UE occurrence in the patients with he-matological diseases(P＜0.05).The results of restricted cubic spline showed that there was a"U"-type non-linear relationship between age and UE risk(X2=17.710,P＜0.05),and the risk of UE was the lowest when the age was 30 years old.Conclusion In PICC,the emphasis should be paid to the male patients with hemato-logical malignancies who have repeated punctures during catheterization,no intracardiac electrocardiographic positioning during catheterization,bleeding tendency,indwelling polyurethane catheters and repeated catheter-related complications in order to decrease the UC occurrence probability.
ABSTRACT
Objective To analyze risk factors for perioperative blood transfusion in elderly patients undergoing uni-lateral primary total hip arthroplasty and develop a prediction model.Methods The study retrospectively collected 467 elderly patients receiving unilateral primary total hip arthroplasty between January 2013 and October 2021 at Peking Union Medical College Hospital.The 70%of the data were used as the training set and the 30%of the data were used as the testing set.Patients were divided into the transfusion and no-transfusion groups based on the presence or absence of perioperative blood transfusion.Univariate analysis and multivariable logistic regression were conducted to analyze patient demographic characteristics,surgical information,and preoperative laboratory tests for identifying risk factors.Clinical experience was combined to establish a prediction model and draw the nomogram.The receiver operating characteristic(ROC)curve and calibration curve were used to evaluate the model in the tes-ting set.Results A total of 91 patients(19.5%)received perioperative blood transfusion.Multivariable logistic re-gression suggested the history of coronary artery disease,prolonged operation time,and lower preoperative hemoglo-bin were risk factors for perioperative blood transfusion(P＜0.05).The prediction model was constructed based on the results of statistical analysis and clinical experience,including the history of coronary artery disease,operation time,preoperative hemoglobin,age,and American Society of Anesthesiologists(ASA)physical status＞Ⅱ.The area under the receiver operating characteristic curve(AUC)of the model was 0.809.Conclusions The prediction model for perioperative blood transfusion in elderly patients undergoing unilateral total hip arthroplasty had a good performance and could assist in clinical practice.
ABSTRACT
Objective·To explore the correlation between body compositions and cardiovascular fitness(CRF)in patients with coronary heart disease(CHD).Methods·The CHD patients(CHD group)who underwent elective percutaneous coronary intervention treatment at Renji Hospital,Shanghai Jiao Tong University School of Medicine from October 2022 to June 2023 as well as healthy people(control group)were selected.All the participants completed cardiopulmonary exercise testing(CPET)to determine CRF and bioelectrical impedance analysis(BIA)to determine body compositions on the same day.Results·A total of 191 patients with coronary heart disease and 188 healthy individuals were included.There was no statistically significant difference in baseline characteristics between the two groups.Compared with the control group,the CRF indicators of the CHD group were significantly reduced(all P<0.05).In terms of body composition indicators,the trunk muscle mass(TMM)of the CHD group was significantly lower than that of the control group(P<0.01),and the trunk fat mass(TFM)was significantly higher than that of the control group(P<0.01).Correlation analysis showed that TMM(R=0.538),lower limbs muscle mass(LMM)(R=0.754),and lower limbs fat mass(LFM)(R=0.593)were positively correlated with peak oxygen uptake per kilogram of bodyweight(VO2peak/kg)in the CHD group(all P<0.01),while TFM(R=-0.563)was negatively correlated with VO2peak/kg(P<0.01).There was no statistically significant correlation between other body composition indicators and VO2peak/kg.According to VO2peak/kg,the CHD patients were divided into low CRF group,medium CRF group,and high CRF group.The results showed that there were statistically significant differences in LMM,TMM,LFM,and TFM among the three groups of patients(all P<0.05).Multiple linear regression analysis suggested that age,gender,TMM,TFM,LMM,and LFM were related factors of VO2peak/kg in the patients with CHD.The VO2peak/kg of CHD patients increased with the increase of TMM,LMM,and LFM and the decrease of age and TFM;the female patients had lower VO2peak/kg compared to the males.Conclusion·The CRF of CHD patients is significantly lower than that of the healthy population,with higher TFM and lower TMM;in the CHD patients,CRF is negatively correlated with TFM and positively correlated with TMM,LMM,and LFM.

ABSTRACT
Objective@#To explore two visual acuity standards for examining uncorrected visual acuity (UCVA) to define poor vision in lower grade elementary school students, and to compare the difference of screening myopia rates when combined with non cycloplegic auto refraction (NCAR), so as to provide a scientific basis for standardizing UCVA examination methods using CAR as the gold standard of authenticity and reliability.@*Methods@#From March 22nd to April 9th, 2023, a total of 549 first and second grade students aged 7-8 years from a primary school in Hefei City were selected for the study by convenient cluster sampling method. Two methods were employed for UCVA examination:the first method involved charts where the student could not make mistakes in identifying at least half of the characters per line (V1), and the second method used charts with character sizes ranging from 4.0 -4.5, 4.6-5.0 and 5.1-5.3, without allowing 1, 2 and 3 errors per line (V2). While NCAR was performed, then 187 students underwent CAR examination. Paired Wilcoxon rank-sum test and McNemar test were used to compare the differences between V1 and V2 methods in defining poor vision and screening myopia rates. Using CAR as the gold standard, the authenticity and reliability of defining screening myopia rates through the combination of V1 and V2 methods along with NCAR were evaluated.@*Results@#The UCVA examination results for V1 and V2 showed statistically significant differences in both the right eye [5.0(4.9,5.0), 4.9(4.8,5.0)] and the left eye [ 5.0 (4.9,5.0), 4.9(4.8,5.0)] ( Z=-13.95, -13.34, P <0.01). The detection rates of poor vision for the right eye were 43.53% for V1 and 63.21% for V2, and the left eye with 44.08% for V1 and 62.11% for V2, with statistically significant differences ( χ 2= 106.01 , 95.09, P <0.01). When screening myopia rates were assessed for UCNA methods combined with NCAR, the right eye rates were 21.49% for V1 and 24.59% for V2, and the left eye rates were 21.31% for V1 and 23.13% for V2, with statistically significant differences ( χ 2=15.06, 8.10, P <0.01). Using CAR as the gold standard, the detection rates in the right eye and left eye were 16.58 % and 17.11%, respectively. The Youden indices for defining screening myopia in the right eye were 0.80 for V1 and 0.79 for V2, and the left eye with 0.85 for V1 and 0.83 for V2. The agreement rates for the right eye were 91.98 % for V1 and 89.30% for V2, and the left eye with 94.12% for V1 and 91.98% for V2. The Kappa values for the right eye were 0.73 for V1 and 0.67 for V2, and the left eye with 0.81 for V1 and 0.75 for V2.@*Conclusions@#Authenticity and reliability of two UCVA examination methods combined with NCAR in defining screening myopia are higher in V1 than V2 methods. It is recommended to unify the visual acuity examination methods by requiring the correct identification of more than half of the total number of visual markers in a row.
ABSTRACT
Aim To analyze the differences in plasma biomarkers and metabolic pathways between Atractylodes chinensis and Atractylodes coreana after intervention in spleen deficiency rats, and discuss the spleen strengthening mechanism of the two from a non targeted metabolomics perspective. Methods A spleen deficiency model was established in SD rats using a composite factor method of improper diet, excessive fatigue, and bitter cold diarrhea. To determine the content of gastrointestinal and immunological indicators, UHPLC-QE-MS technology was used, combined with principal component analysis (PC A) and orthogonal projections to latent structures-discriminant analysis (OPLS-DA) methods to search for biomarkers in plasma of spleen deficiency rats, and metabolic pathways were induced using the Pathway database. Results After administration of Atractylodes chinensis and Atractylodes coreana, various indicators in plasma of spleen deficiency rats showed varying degrees of regression. Metabolomics analysis showed that Atractylodes chinensis and Atractylodes coreana respectively recalled 70 and 82 plasma differential metabolites. Atractylodes chinensis mainly regulated two metabolic pathways : "Glycine, serine, and threonine metabolism, and "Thiamine metabolism". Atractylodes coreana mainly regulated five metabolic pathways, "Glycine, serine, and threonine metabolism", "Thiamine metabolism, "Pyrimidine metabolism", "Butanoate metabolism", and "Riboflavin metabolism". Conclusions Both Atractylodes chinensis and Atractylodes coreana have certain regulatory effects on spleen deficiency rats, and their mechanism of action may be related to regulating metabolic pathways such as "Glycine, serine, and threonine metabolism, and "Thiamine metabolism"in spleen deficiency.
ABSTRACT
Background/Aims@#Functional dyspepsia (FD) overlapping with other gastrointestinal disorders are quite common. The characteristics of FD overlap in Chinese population with latest Rome IV criteria were unclear. This large-scale outpatient-based study assessed the characteristics of FD overlap in South China. @*Methods@#Consecutive FD patients visited the Gastroenterology Clinic at 2 tertiary medical centers in Hangzhou, China who fulfilled the Rome IV criteria were enrolled. Complete questionnaires related to the gastrointestinal symptoms (Rome IV criteria), Reflux Disease Questionnaire, anxiety and depression, quality of sleep and life, and demographic information were collected. @*Results@#Among the total of 3281 FD patients, 50.69% overlapped with gastroesophageal reflux disease, 21.46% overlapped with irritable bowel syndrome, 6.03% overlapped with functional constipation. FD overlap had higher proportion of single/divorced/widowed rate, high education level, being employed, drinking, night shift, unhealthy dietary habit than FD only (P < 0.05). They had higher frequency of consultation and economic burden, as well as lower scores in quality of life (P < 0.001). Multivariate logistic regression showed that increasing age, female, low body mass index, history of gastroenteritis, anxiety, depression, and poor sleep quality were independent risk factors for FD overlap. @*Conclusions@#FD overlap was quite common in China with high economic burden and poor quality of life, FD patients with history of gastroenteritis, anxiety, depression, and poor sleep quality were more likely to have overlap disorders. Awareness of the physical and psychosocial stressors in overlapping condition would help optimize the management of FD overlap in clinical practice.

Objective To investigate the impacts of Nalbuphine combined with Sufentanil on postoperative analgesia and stress response in patients undergoing laparoscopic colorectal cancer surgery.Methods 86 patients who underwent laparoscopic colorectal cancer surgery from August 2020 to April 2022 were collected and grouped into an experimental group and a control group according to the analgesic plan,with 43 patients in each group.The control group was given Sufentanil after surgery,and the experimental group was given Nalbuphine + Sufentanil.The analgesic and sedative effects at different time points after surgery(1,6,12,24 and 48 h),and the changes in serum pain mediator and stress response indicators were observed and compared.The time of getting out of bed after surgery,the number of patient-controlled analgesia,the number of cases of remedial analgesia,the recovery of gastrointestinal function,and the occurrence of adverse reactions within 48 hours after surgery were recorded in both groups.Results Compared with the control group,the experimental group had a shorter time to get out of bed for the first time after surgery(t = 3.29,P = 0.001),and had fewer instances of patient-controlled analgesia(Z = 4.53,P = 0.000)and cases of remedial analgesia(χ2 = 4.48,P = 0.034);Postoperative 12,24 and 48 h after surgery,the visual analogue scale(VAS)in the experimental group was obviously lower than that in the control group(t = 2.86,t = 2.55,t = 0.10,P<0.05);Postoperative 1 and 6 h,the Ramsay sedation score in the experimental group patients was lower than that in the control group(t = 2.10,t = 2.07,P<0.05);Postoperative 6,12 and 24 h,the serum substance P(SP)(t = 3.63,t = 5.51,t = 3.46,P<0.05)and prostaglandin E2(PGE2)(t = 2.34,t = 3.56,t = 0.33,P<0.05)levels in the experimental group were obviously lower than those in the control group;Postoperative 6,12 and 24 h,the serum cortisol(Cor)level in the experimental group was obviously lower than that in the control group(t = 4.65,t = 6.50,t = 6.52,P<0.05);Postoperative 6,12,24 and 48 h,the serum norepinephrine(NE)(t = 5.49,t = 7.85,t = 7.70,t = 2.18,P<0.05),tumor necrosis factor-α(TNF-α)(t = 5.43,t = 7.83,t = 5.27,t = 2.32,P<0.05),and hypersensitivity C-reactive protein(hs-CRP)(t = 3.39,t = 9.241,t = 4.87,t = 2.37,P<0.05)levels in the experimental group were obviously lower than those in the control group.There was no statistically obvious difference between the two groups in terms of postoperative exhaust time,defecation time,bowel sounds occurrence time,and incidence of adverse reactions(P>0.05).Conclusion Nalbuphine combined with Sufentanil is effective in postoperative analgesia of laparoscopic colorectal cancer patients,and can effectively regulate the post-traumatic stress response of the body after surgery.
ABSTRACT
Objective:To explore the expression and clinical significance of heme oxygenase-1 (HO-1) and quinone oxidoreductase (NQO-1) in children with different severity levels of mycoplasma pneumoniae (MP) infection.Methods:A total of 140 children with MP infection who were treated at the Affiliated Hospital of Jining Medical University from January to June 2022 were selected as the observation group, while 100 healthy children who underwent physical examination were selected as the control group. The serum levels of interleukin-2 (IL-2), IL-6, IL-10, IL-1β, tumor necrosis factor α (TNF-α), interferon γ (IFN-γ), HO-1, and relative expression of NQO-1 protein were compared between the control group and the observation group, as well as between children with different degrees of MP infection, Forced vital capacity (FVC), maximum expiratory volume in the first second (FEV 1), peak expiratory flow rate (PEF), 50% forced expiratory flow rate and maximum mid expiratory flow rate (MEF 25-70), 50% forced expiratory flow rate (MEF 50), and 25% forced expiratory flow rate (MEF 25). Pearson correlation method was used to analyze the correlation between the expression of HO-1 and NQO-1 with inflammatory factors and lung function indicators. The receiver operating characteristic (ROC) curve was used to analyze the value of HO-1 and NQO-1 expression in predicting severe MP. Results:The serum levels of IL-2, IL-6, IL-10, IL-1β, TNF-α, IFN-γ, and HO-1 in the observation group were significantly higher than those in the control group (all P<0.05), while the relative expression level of NQO-1 protein was significantly lower than that in the control group ( P<0.05). The FVC, FEV 1, PEF, MEF 25-70, MEF 50, and MEF 25 in the observation group were significantly lower than those in the control group (all P<0.05). The serum levels of IL-2, IL-6, IL-10, IL-1β, TNF-α, IFN-γ, and HO-1 in the observation group of severe children were significantly higher than those in mild children (all P<0.05), while the relative expression of NQO-1 protein, FVC, FEV 1, PEF, MEF 25-70, MEF 50, and MEF 25 were significantly lower than those in mild children (all P<0.05). HO-1 in children with MP infection is positively correlated with IL-6, IL-1β, and IFN-γ, while the relative expression level of NQO-1 protein is negatively correlated with IL-6, IL-1β, and IFN-γ (all P<0.05); HO-1 was negatively correlated with MEF 50 and MEF 25, while the relative expression level of NQO-1 protein was positively correlated with MEF 50 (all P<0.05). The area under the ROC curve for predicting the relative expression levels of HO-1 and NQO-1 proteins in severe MP was 0.871 and 0.934, respectively (all P<0.05). Conclusions:The expression of serum HO-1 and NQO-1 in children with MP infection is correlated with cytokines and lung function indicators, and has certain application value in predicting severe illness.

The mean age of benign and malignant breast tumor groups was 29.6±11.6 years and 46.7±14.3 years, the mean tumor size in pathological examination was 3.3±2.1 cm and 2.0±0.8 cm, and the operative time was 138.9±57.0 min and 177.3±46.3 min, respectively. One patient had positive resection margin and underwent intraoperative extended resection in the malignant breast tumor group. All the patients were successfully followed up, and the mean follow-up time of benign and malignant breast tumor groups was 6.8±4.0 months and 8.7±4.9 months, respectively. No complications or tumor recurrence occurred. The scores of psychosocial status, sexual well-being, chest wall status and breast satisfaction decreased one month after surgery and basically recovered to the preoperative level in one year, and the score of scar appearance increased to 64.6±5.9 points one year postoperatively. Conclusion Endoscopic assisted transaxillary breast tumor resection can effectively improve postoperative cosmetic effect and patient satisfaction on the premise of safety.
ABSTRACT
With the continuous development of traditional Chinese medicine （TCM）， the requirement for the quality of Chinese medicines has become increasingly higher since they have been widely used in clinical practice. Chinese medicinal materials are the material basis for the inheritance and development of TCM， and their quality directly affects the clinical efficacy. Studying the quality of Chinese medicinal materials is the key to ensure the quality and realize the large-scale application. As one of rare Chinese medicinal materials， Cistanches Herba has the functions of tonifying kidney yang， invigorating blood and essence， moistening intestines to relieve constipation. High-quality Cistanches Herba is characterized by glossy appearance， high density， fleshy and soft texture， and sweet taste. With the reduction of wild resources， the products from cultivated Cistanche deserticola or C. tubulosa become dominant on the market of Cistanches Herba. The cultivation areas are widely distributed， mainly concentrated in Gansu， Inner Mongolia， and Xinjiang. However， the cultivated products have varied quality due to the differences in germplasm， producing region， cultivation method， harvesting， and processing. According to the theories of quality evaluation based on morphological characteristics and excellent appearance indicating high quality， this paper reviewed the literature on the quality evaluation， growth， development， and processing of Cistanches Herba in the last decade to explore the main factors （genetic characteristics， environmental conditions， and harvesting and processing factors） affecting the quality of Cistanches Herba. The review aims to explore the factors for the high quality and provide a reference for the producing region screening， directional cultivation， and production of Cistanches Herba.
ABSTRACT
The solute carrier family 4 (SLC4) includes 10 members (SLC4A1-5, SLC4A7-11), which are expressed in multiple tissues in the human body. The SLC4 family members differ in their substrate dependence, charge transport stoichiometry and tissue expression. Their common function is responsible for the transmembrane exchange of multiple ions, which is involved in many important physiological processes, such as erythrocyte CO2 transport and the regulation of cell volume and intracellular pH. In recent years, many studies have focused on the role of SLC4 family members in the occurrence of human diseases. When SLC4 family members have gene mutations, a series of functional disorders will occur in the body, leading to the occurrence of some diseases. This review summarizes the recent progress about the structures, functions and disease correlation of SLC4 members, in order to provide clues for the prevention and treatment of related human diseases.

OBJECTIVE@#To explore the effect of hypoxia-supported umbilical cord mesenchymal stem cell (UC-MSC) on the expansion of cord blood mononuclear cell （MNC） in vitro.@*METHODS@#The isolated cord blood mononuclear cells were inoculated on the preestablished umbilical cord mesenchymal stem cell layer and cultured under hypoxic conditions (3％ O2) and the experimental groups were normoxia (MNCs were cultured under normoxic conditions), hypoxia (MNCs were cultured under hypoxic conditions), UC-MSC (MNCs were cultured with UC-MSC under normoxic conditions), and UC-MSC+hypoxia (MNCs were cultured with UC-MSC under hypoxic conditions). To further investigate the combinational effect of 3 factors of SCF+FL+TPO (SFT) on expansion of cord blood MNCs in vitro in hypoxia-supported UC-MSC culture system, the experiments were further divided into group A (MNCs were cultured with UC-MSC and SFT under normoxic conditions), group B (MNCs were cultured with UC-MSC under hypoxic conditions), group C (MNCs were cultured with UC-MSC and SFT under hypoxic conditions). The number of nucleated cells (TNC), CD34+ cell, CFU and CD34+CXCR4+, CD34+CD49d+, CD34+CD62L+ cells of each groups were detected at 0, 7, 10 and 14 days, respectively.@*RESULTS@#Compared with group hypoxia and UC-MSC, group UC-MSC+hypoxia effectively promoted the expansion of TNC, CD34+ cell and CFU, and upregulated the expression level of adhesion molecule and CxCR4 of the cord blood CD34+ cell（P<0.05）. After culturing for 14 days, compared with group A and group B, group C effectively promoted the expansion of cord blood MNC at different time points（P<0.05）, and the effect of group A was better than that of group B at 7 and 10 days（P<0.05）.@*CONCLUSION@#Hypoxia-supported UC-MSC efficiently promoted the expansion and expression of adhesion molecule and CXCR4 of cord blood CD34+ cell, and the effect of expansion could be enhanced when SFT 3 factors were added.

OBJECTIVE@#To explore the clinical manifestations, diagnosis, treatment and prognosis of blastic plasmacytoid dendritic cell neoplasm(BPDCN).@*METHODS@#The clinical features, bone marrow morphology and immunophenotyping, treatment and prognosis of 4 patients with BPDCN were analyzed retrospectively.@*RESULTS@#4 patients had bone marrow， spleen and lymph nodes involvement， 2 patients had skin lesions， and 3 patients had central nervous system infiltration． Tailing phenomenon of abnormally cells could be seen in bone marrow. The immunophenotyping showed that CD56, CD4 and CD123 expression was observed in 4 patients， and CD304 in 3 patients． One patient refused chemotherapy and died early. Both patients achieved complete remission after the initial treatment with DA+VP regimen, 1 of them achieved complete remission after recurrence by using the same regimen again． One patient failed to respond to reduced dose of DA+VP chemotherapy, and then achieved complete remission with venetoclax+azacitidine.@*CONCLUSION@#The malignant cells in BPDCN patients often infiltrate bone marrow, spleen and lymph nodes, and have specical phenotypes, with poor prognosis. The treatment should take into account both myeloid and lymphatic systems. The treatment containing new drugs such as BCL-2 inhibitors combined with demethylation drugs is worth trying.

Long non-coding RNA (lncRNA) is a hot topic in the field of researching tumor pathogenesis, and the importance in hematologic malignancies has been gradually being elucidated. LncRNA not only regulates hematological tumorigenesis and progression through affecting various biological processes such as cell proliferation, differentiation, pluripotency and apoptosis; moreover, abnormal expression and mutation of lncRNA are closely related to drug resistance and prognosis. Thus lncRNA can be used as novel biomarker and potential therapeutic target for hematological tumors. In this review, we will focus on the latest progress of lncRNA in hematological tumors to provide new ideas for the clinical diagnosis, prognostic evaluation together with research and development of target drugs for hematologic malignancies.

OBJECTIVE@#To evaluate the changes of periodontal phenotype (width of keratinized gingiva, thickness and height of alveolar bone) of lower anterior teeth in patients with skeletal class Ⅲ malocclusion before and after the periodontal-orthodontic-orthognathic combined treatment.@*METHODS@#In the study, 20 patients with skeletal class Ⅲ malocclusion (6 males and 14 females) completed the periodontal-orthodontic-orthognathic combined treatment were included from March 2017 to June 2022, with 39 central incisors, 40 lateral incisors and 40 canines. The mean age was (25.40±4.27) years (20-34 years). The mean follow-up time was (3.70±1.05) years from the beginning of periodontal corticotomy regenerative surgery (PCRS) to the end of the combined treatment. Cone-beam computed tomography (CBCT) was used to measure the thickness, area and height of alveolar bone by the same researcher, taken before the PCRS (T0), 6 months after the PCRS (T1), 12 months after the PCRS (T2), before the orthognathic surgery (T3), and after the periodontal-orthodontic-orthognathic combined treatment (T4). The periodontal clinical parameters were used to evaluate changes in the soft tissue by another researcher, measured before the PCRS (T0) and after the combined treatment (T4). Changes of soft and hard tissue were evaluated by the periodontal phenotype.@*RESULTS@#The width of keratinized gingiva increased significantly (all P < 0.001) in lower anterior teeth, the central incisors, lateral incisors and canines increased by (1.82±1.57) mm, (2.03±1.48) mm and (2.05±1.27) mm, respectively. The proportion of thick periodontal biotype in the central and lateral incisors increased significantly (all P < 0.001), while the changes of periodontal biotypes in the lower canines were not obvious. The thickness of labial alveolar bone of lower anterior teeth all increased significantly after periodontal corticotomy regenerative surgery and the combined treatment (all P < 0.001). The area of labial alveolar bone of lower anterior teeth also increased significantly after the combined treatment (all P < 0.001). The whole area of labial and lingual alveolar bone of central and lateral incisors increased (P < 0.001), while the whole area of canines remained the same. All The height of the alveolar bone increased (all P < 0.001) on the labial side after the treatment.@*CONCLUSION@#The periodontal phenotypes of lower anterior teeth were significantly improved after the periodontal-orthodontic-orthognathic combined treatment in patients with skeletal Angle class Ⅲ malocclusion. The improvement was long-termly stable, and the periodontal risk was reduced.
