Objective To analyze the disease burden of chronic kidney diseases (CKD) attributed to high body mass index (BMI) in China from 1992 to 2021 and predict the disease burden for the next decade, and to provide evidence for the prevention and treatment of CKD. Methods Using the Global Burden of Disease (GBD) database and the Joinpoint model, the average annual percentage rate change (AAPC) of the mortality rate and disability-adjusted life year (DALY) rate was calculated to describe and analyze the CKD disease burden attributed to high BMI in China from 1992 to 2021. The ARIMA model was employed to predict and analyze the change trend of the CKD disease burden. Results From 1992 to 2021, the mortality rate and DALY rate attributed to high BMI-induced chronic kidney disease showed an upward trend. Compared to 1992, the attributed number of deaths increased by 324.38%, and DALYs increased by 268.56%; the mortality rate increased by 64.00%, and the DALY rate grew by 51.62%. From 1992 to 2021, the mortality rate and DALY rate for males were lower than those for females, but the growth rate for males exceeded that of females. From 1992 to 2021, the mortality rate and DALY rate of chronic kidney disease attributed to high BMI in China increased with age. The average annual change rate of chronic kidney disease attributed to high BMI in China from 1992 to 2021 (mortality rate: 1.40 per 100,000 (95% CI: 1.04–1.76), DALY rate: 1.43 per 100 000 (95% CI: 1.17–1.70)) was higher than thHuaiyin Normal University, Huai'anher social demographic index (SDI) regions. The ARIMA model predicted that the age-standardized mortality rate increased from 2.91 per 100 000 in 2022 to 3.05 per 100 000 in 2026, and the age-standardized DALY rate increased from 69.65 per 100 000 in 2022 to 73.58 per 100 000 in 2026. Conclusion Chronic kidney disease attributed to high BMI in China is on the rise, and it will continue to grow in the future. The focus of CKD prevention and control should be on males and the elderly, while active measures should be taken to reduce the occurrence and progression of chronic kidney disease.

Depression (Dep) is one of the most common concomitant symptoms of Parkinson's disease (PD), but there is a lack of detailed pathologic evidence for the occurrence of PD-Dep. Currently, the management of symptoms from both conditions using conventional pharmacological interventions remains a formidable task. In this study, we found impaired activation of extracellular signal-related kinase (ERK), reduced levels of transcription and translation, and decreased expression of brain-derived neurotrophic factor (BDNF) in the medial prefrontal cortex (mPFC) of PD-Dep rats. We demonstrated that the abnormal phosphorylation of α-synuclein (pS129) induced tropomyosin-related kinase receptor type B (TrkB) retention at the neuronal cell membrane, leading to BDNF/TrkB signaling dysfunction. We chose SEW2871 as an ameliorator to upregulate ERK phosphorylation. The results showed that PD-Dep rats exhibited improvement in behavioral manifestations of PD and depression. In addition, a reduction in pS129 was accompanied by a restoration of the function of the BDNF/ERK signaling loop in the mPFC of PD-Dep rats.

Objective:To analyze the three-dimensional radiographic characteristics of calcifying odon-togenic cyst and calcifying epithelial odontogenic tumor using spiral computed tomography(CT)and cone-beam computed tomography(CBCT).Methods:Clinical records,histopathological reports,and CBCT or non-enhanced spiral CT images of 19 consecutive patients with calcifying odontogenic cyst(COC)and 16 consecutive patients with calcifying epithelial odontogenic tumor(CEOT)were retrospec-tively acquired,and radiographic features,including location,size,expansion,internal structure and calcification,were analyzed.Results:Among the 19 COC cases(12 males and 7 females,with an average age of 27 years),89.5％(17/19)of the lesions originated from the anterior and premolar areas,100.0％of them exhibited cortex expansion,and 78.9％had discontinued cortex.Among the 16 CEOT cases(3 males and 13 females,with an average age of 36 years),81.3％(13/16)of the lesions were in the premolar and molar areas,56.3％of them exhibited cortex expansion,and 96.8％had discontinued cortex.According to the distribution of internal calcifications,these lesions were divided in-to:Ⅰ(non-calcification type):absence of calcification;Ⅱ(eccentric marginal type):multiple calcifi-cations scattered along one side of the lesion;Ⅲ(diffused type):numerous calcifications diffusely dis-tributed into the lesion;Ⅳ(plaque type):with a ≥ 5 mm calcified patch;V(peri-coronal type):multiple calcifications clustered around impacted teeth.Calcifications were present in 73.7％of COC le-sions,including 9 type Ⅱ,3 type Ⅲ and 2 type Ⅳ lesions,and 42.8％of CEOT lesions had calcifica-tion images,including 2 type Ⅲ and 5 type V lesions.Six COC lesions had odontoma-like images.Moreover,8 of 9 type Ⅰ CEOTs were histologically Langerhans cell-rich subtype,which had a smaller size(with an average mesiodistal diameter of 17.8 mm)and were not associated with impacted teeth.Conclusion:COC lesions tended to originate from the anterior part of the jaw and exhibit cortex expan-sion,and were sometimes associated with odontoma.CEOT commonly occurred in the posterior jaw and had discontinued cortex.Two lesions had significantly different calcification map.Over 70％of COC le-sions had calcification images,which were mostly scattered along one side of the cysts,far from the im-pacted teeth.Approximately 60％of CEOT lesions exhibited smaller size and non-calcification,and the remaining CEOT cases often had calcification images clustered around the impacted teeth.

Objective:To investigate a new method for the reconstruction of hemifacial microsomia by sagittal osteotomy of the affected mandibular outer cortex combined with bone graft of mandibular outer cortex from healthy side.Methods:From March 2006 to March 2023, the clinical data of patients with hemifacial microsomia admitted to the Department of Craniomaxillofacial Surgery, Plastic Surgery Hospital, Chinese Academy of Medical Sciences were analyzed retrospectively. Preoperative diagnosis and surgical design were performed based on clinical manifestations and imaging findings. All cases were operated under general anesthesia. The affected mandibular outer cortex was previously split by an intraoral approach, and then the mandibular outer cortex of appropriate shape and size on the healthy side was harvested and grafted into the split bone space according to the preoperative design, following by internal rigid fixation. Complications, facial appearance improvement, and patient satisfaction were followed up. Photographs were taken preoperative, immediately postoperative and at the long-term(last) postoperative follow-up, and the severity of the deformity was analyzed. CT data from preoperative, immediate postoperative, and long-term follow-up visits were imported into Surgicase Proplan medical three-dimensional image workstation in Dicom format. The mandible was reconstructed using Segmentation, and the thickness of the mandible was measured during pre-operative, immediate post-operative and long-term follow-up visits. Anova with repeated measurement design was used to compare measurements and LSD test was used for multiple comparisons. The Kruskal-Wallis rank sum test were used to statistically analyze malformation severity. P< 0.05 is considered statistically significant. Results:A total of 39 patients were included in this study, including 13 females and 26 males, with an average age of (22.21±4.57) years (15-27 years). All patients were followed up for an average of (45.56±39.41) months (6-153 months) after surgery. The grafted mandibular outer cortex grows well with the adjacent bone tissue, and the mandibular angle and mandibular body are significantly wider. Of the 39 cases, 1 developed an infection 1 year after surgery, the titanium plate was exposed, and the patient healed after debridement and removal of the immobilizing splint. The facial appearance of the other patients improved significantly. Preoperative, immediate postoperative and long term follow up of mandibular thickness measurements were compared in pairs, and the differences were statistically significant (all P<0.05). The patient’s appearance satisfaction score: the preoperative score was [2.0(1.5, 2.0)] points, the immediate postoperative score was [4.0(4.0, 4.0)] points, the score of the last postoperative follow up was [4.0(4.0, 4.0)] points. There was statistical difference in satisfaction among the three groups ( P<0.01). The preoperative scores were compared with the scores of the immediate postoperative and the last postoperative follow-up respectively, and the differences were statistically significant( P<0.01). There was no statistical significance in satisfaction between the immediate postoperative score and the score of the last postoperative follow up ( P>0.05). Conclusion:The sagittal splitting osteotomy of the mandibular outer cortex is consistent with the features of mandibular anatomy, and provides a good condition for the grafting and healing of autogenous bone. Removing the outer cortex of the mandible on the healthy side not only increases the thickness of the affected side, but also decreases the width of the angle of the mandible on the healthy side, so as to effectively correct the asymmetric deformity of the mandible. The method is simple, with few complications and good results, and is one of the ideal treatments to correct hemofacial microsomia.

Uncovering the risk factors of pulmonary hypertension and its mechanisms is crucial for the prevention and treatment of the disease.In the current study,we showed that experimental periodontitis,which was established by ligation of molars followed by orally smearing subgingival plaques from patients with periodontitis,exacerbated hypoxia-induced pulmonary hypertension in mice.Mechanistically,periodontitis dysregulated the pulmonary microbiota by promoting ectopic colonization and enrichment of oral bacteria in the lungs,contributing to pulmonary infiltration of interferon gamma positive(IFNγ+)T cells and aggravating the progression of pulmonary hypertension.In addition,we identified Prevotella zoogleoformans as the critical periodontitis-associated bacterium driving the exacerbation of pulmonary hypertension by periodontitis,and the exacerbation was potently ameliorated by both cervical lymph node excision and IFNγ neutralizing antibodies.Our study suggests a proof of concept that the combined prevention and treatment of periodontitis and pulmonary hypertension are necessary.

Objective To explore the effects of repetitive transcranial magnetic stimulation(rTMS)combined with synchronous working memory training on memory,attention,executive function and other cognitive functions in stroke patients.Methods A total of 100 stroke inpatients and outpatients admitted in Department of Rehabilitation Medicine of Hongqi Hospital Affiliated to Mudanjiang Medical College from January 2022 to May 2023 were enrolled and randomly divided into a synchronous group(simultaneous rTMS and working memory training),a rTMS group,a working memory training group,and a control group(no cognitive training),there were 25 case in each group.Stroop test,Rivermead behavioral memory test,Montreal cognitive assessment(MoCA),modified Barthel index(MBI)test,and Fugl-Meyer test were applied before and after treatment.Results There were no significant differences in above test scores among the four groups before treatment(P＞0.05).After treatment,Stroop test showed that the synchronization group had significantly higher accuracy rates of the baseline phase and the conflict phase than the other three groups(P＜0.05),shorter reaction time of the baseline phase than the working mem-ory training group and the control group(1043.76±260.38 ms vs 1299.36±468.86 ms and 1418.68±412.25 ms,P＜0.05),and shorter reaction time of the conflict phase than the control group(P＜0.05).The synchronization group scored statistically higher scores than the other three groups in the Rivermead behavioral memory test,MoCA test,modified Barthel test,and Fugl-Meyer test(P＜0.05).Conclusion rTMS combined with synchronous working memory training can effectively improve the cognitive function in stroke patients.

AIM:This study aims to examine the ependymin-related protein 1(EPDR1)expression in various tissues from wild-type C57BL/6 mice and type 2 diabetes(db/db)mice.The impact of EPDR1 on lipid accumulation in al-pha mouse liver 12(AML12)hepatocytes was also investigated.METHODS:Western blot was used to detect EPDR1 protein expression in the heart,liver,spleen,lung,kidney,gastrocnemius,brown adipose and brain tissues of C57BL/6 mice.Western blot and immunohistochemical(IHC)staining were also used to compare EPDR1 protein expression in the liver,gastrocnemius muscle,heart and kidney tissues of db/db and C57BL/6 mice.To develop an AML12 cell lipid deposi-tion model,palmitic acid(PA)+oleic acid(OA)was used,and the cells were transfected with adenovirus overexpressing EPDR1 or treated with exogenous recombinant EPDR1 protein(rEPDR1).ELISA was conducted to determine intracellu-lar triglyceride(TG)content,and oil red O staining was employed to assess the effect of EPDR1 on lipid accumulation in AML12 cells.RESULTS:Western blot and IHC staining results revealed that EPDR1 was widely expressed in various tis-sues of wild-type mice,with the liver exhibiting the highest protein expression level.However,EPDR1 expression was down-regulated in the liver,gastrocnemius muscle,heart and kidney tissues in diabetic db/db mice compared with wild-type mice.Oil red O staining revealed that overexpression of EPDR1 in AML12 liver cells or rEPDR1 treatment led to re-duced lipid accumulation.Furthermore,the TG content significantly decreased compared with the model group(P<0.05).CONCLUSION:EPDR1 is expressed in various tissues of wild-type mice,but showed diminished expression in the liver tissues of diabetic mice.Nevertheless,enhancing the expression of EPDR1 can aid in reducing lipid accumula-tion in hepatocytes.These findings provide an experimental foundation for further exploration of the role of EPDR1 in the development of fatty liver in diabetic liver tissue.
