There are practical and cost-effective opportunities for the prevention and early intervention of periodontal disease, a common oral condition. Depression and anxiety represent major global mental health challenges, and they are characterized by high prevalence rates and an elevated suicide risk. Their clinical management is complicated by extended treatment timelines and substantial healthcare costs. Accumulating evidence demonstrates a statistically significant bidirectional association between periodontal disease and depression/anxiety disorders. However, established clinical pathways integrating these conditions remain lacking. This review presents a comprehensive analysis of current research examining the relationship between periodontal disease and mood disorders, specifically depression and anxiety. This study explored the bidirectional mechanisms within the microbiota-oral-brain axis, which includes both periodontal disease inducing neuroinflammation through pro-inflammatory factors, such as interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) activating the TLR-4/NF-κB signaling pathway, and depression and anxiety leading to “glucocorticoid resistance” through hypothalamic-pituitary-adrenal (HPA) axis dysregulation, thus causing dual immune dysfunction that exacerbates periodontal tissue destruction, as well as the mechanisms by which biological, psychological, and social factors contribute to the bidirectional association between periodontal disease and depression/anxiety. We propose implementing bidirectional referral protocols between dental and psychiatric services in clinical practice, incorporating mental health screening tools, such as Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7(GAD-7), for patients with moderate-to-severe periodontal disease, and incorporating periodontal examination into routine assessment during psychiatric services. This multidisciplinary approach aims to break the vicious circle between these conditions and provide clinicians with pragmatic intervention strategies.

OBJECTIVE To systematically evaluate the quality of the Heat-clearing and symptom-relieving formula and screen potential marker components that influence the quality of the formula. METHODS The contents of 11 components （calycosin-7- O - β -D-glucoside， ononin， hyperoside， isoquercitrin， baicalin， baicalein， cryptotanshinone， tanshinone Ⅱ A ， tanshinone Ⅰ， senkyunolide A， ferulic acid） in the Heat-clearing and symptom-relieving formula were determined by high-performance liquid chromatography-tandem mass spectrometry （HPLC-MS/MS）. Using the contents of the aforementioned components as variables， cluster analysis （CA）， principal component analysis （PCA）， and orthogonal partial least squares-discriminant analysis （OPLS-DA） were conducted using OriginPro 2024 software and SIMCA 14.1 software； marker components affecting the quality of the Heat-clearing and symptom-relieving formula were then screened based on the criteria of variable importance in the projection （VIP） value＞1 and P ＜0.05. The comprehensive evaluation of 20 batches of samples was carried out using the entropy weight-technique for order preference by similarity to ideal solution（TOPSIS） and grey correlation analysis （GCA） methods. RESULTS The contents of the above 11 components were 7.993-72.866， 4.542-31.228， 727.666-1 901.884， 496.846-1 293.279， 1 995.501-6 779.150， 54.500-241.280， 150.302-304.339， 79.698-189.206， 257.118-682.418， 5.498-21.687， 7.524-26.935 μg/g. CA， PCA and OPLS-DA results showed that 20 batches of samples were grouped into 2 categories. Q1， Q3， Q4， Q7-Q9， Q12， Q15， Q16 were grouped into one category， and the rest were grouped into another category； VIP values of ferulic acid， tanshinone Ⅱ A ， baicalin， cryptotanshinone， calycosin-7- O - β -D-glucoside and ononin were all greater than 1 （ P ＜0.05）. Both the entropy weight-TOPSIS and GCA methods showed that the samples ranked in the top 11 according to the euclidean distance and relative correlation degree were Q2， Q5， Q6， Q10， Q11， Q13， Q14， Q17-Q20. CONCLUSIONS The established HPLC-MS/MS method is rapid， accurate and highly sens itive. Combined with chemical pattern recognition analysis， entropy weight-TOPSIS and GCA methods， this method can be used to evaluate the quality of the Heat-clearing and symptom-relieving formula. Ferulic acid， tanshinone Ⅱ A ， baicalin， cryptotanshinone， calycosin-7- O - β -D-glucoside and ononin may be the marker components that affect the quality of this formula. The overall quality of 11 batches of the Heat-clearing and symptom-relieving formula， including Q17， is relatively superior.

Objective:To analyze the clinical features and risk factors for renal injury in children with antineutrophil cytoplasmic antibody (ANCA)-positive IgA vasculitis (IgAV).Methods:A case-control study was conducted. Seventy-two ANCA-positive IgAV children hospitalized at the Children′s Hospital of Chongqing Medical University from January 2017 to October 2022 were enrolled as the ANCA-positive group. Propensity score matching (1∶4) using the nearest neighbor was performed with age and gender as covariate, and 288 cases ANCA-negative IgAV children were included as the ANCA-negative group. Patients with renal injury were named ANCA-positive IgAV nephritis (IgAVN) group and ANCA-negative IgAVN group, respectively. The ANCA-positive IgAVN group was further divided into myeloperoxidase (MPO) group and proteinase 3 (PR3) group based on the type of ANCA. Clinical data including manifestations, laboratory tests, renal injury, and prognosis were collected. Comparisons between groups were performed using independent sample t-tests, Mann-Whitney U tests, χ2 tests, or Fisher′s exact tests. Kaplan-Meier curves were used to assess differences in the time to renal injury onset, and multivariate logistic regression was performed to identify independent risk factors for renal injury. Results:Among the 72 ANCA-positive IgAV children (41 males, 31 females, age of 7.7 (5.3, 11.2) years), no significant difference in age or gender was observed compared to the ANCA-negative group (both P>0.05). The ANCA-positive group had higher IgM levels, a higher incidence of recurrent rash, and shorter thrombin time (all P<0.05). Among children with renal injury, the ANCA-positive group showed significant differences in the incidence of hematuria, clinical classification, and grade A prognosis compared to the ANCA-negative group (all P<0.05), but no difference was found in the time to renal involvement onest or renal pathology (all P>0.05). The MPO group had higher rates of microscopic hematuria, gross hematuria, acute renal insufficiency, glomerular sclerosis, and grade B prognosis compared to the ANCA-negative IgAVN group (all P<0.05), with a later onset of renal involvement ( P<0.05). Elevated serum creatinine ( OR=1.08, 95% CI 1.03-1.14) and shortened thrombin time ( OR=0.71, 95% CI 0.55-0.92) were independent risk factors for renal injury in ANCA-positive IgAV children (all P<0.05). Conclusions:Children with ANCA-positive IgAV are more likely to experience recurrent rash. MPO-ANCA-positive IgAVN children have higher risks of hematuria, acute kidney injury and glomerular sclerosis, with later-onset but poorer renal prognosis compared to ANCA-negative IgAVN children. Higher serum creatinine levels and shorter thrombin time may be associated with renal injury in children with ANCA-positive IgAV.

For centuries, people have been searching for ways to reconstruct the mutilated thumb and fingers. Among the hundreds of operation methods that have appeared, the method of toe transplantation to reconstruct the thumb and fingers, which appeared in the second half of the 19 th century, had the best effect. However, due to the limitation of technical level at that time, only the pedicled toe could be transplanted to reconstruct the thumb and fingers. During the treatment period, the patient was in an inappropriate position where the hand and foot were fixed together for a long time, and the nerve was not repaired, so the thumb and fingers reconstructed after surgery had poor feeling. Therefore, it has not been widely used. It was not until 1966 when Yang Dongyue succussed in reconstructing the thumb using a free toe transplant with blood vessel anastomosis that toe transplantation gradually became the mainstream method of thumb and finger reconstruction. The appearance and function of the thumb and finger reconstructed by toe transplantation are still very different from that of the normal thumb and finger. Moreover, when multiple thumbs and fingers are defective, the transplantation of multiple toes for repair will cause great damages to the foot, so it is not suitable to reconstruct more than three thumb and fingers using toes in the same period. In 2007, Wang Zengtao proposed the concept of "full-finger reconstruction of thumb and fingers" and a series of new operation methods: new fingers were designed and assembled by means of using a variety of tissue combination assembly, which changed the traditional method of toe transplantation to reconstruct thumb and fingers, and the method of replacing thumb and fingers by toes was changed to manufacturing new thumb and fingers so that the toes could be retained and the thumb and fingers could be reconstructed with approximately normal shape and function. In recent years, the concept and series of new operation methods of thumb and finger reconstruction have been popularized at home and abroad. This paper focuses on the development of full-finger reconstruction of thumb and fingers.

Objective:To investigate the correlationship between an artificial intelligence-based e-Boston bowel preparation scale (e-BBPS) system score and the adenoma miss rate.Methods:Colonoscopy images of 4 373 patients at the Endoscopy Center of Renmin Hospital of Wuhan University from December 21, 2017 to December 31, 2019 were collected for model training. Patients who underwent colonoscopy at the Eighth Affiliated Hospital of Sun Yat-sen University from October 8, 2021 to November 9, 2022 were prospectively included. Patient's bowel preparation was evaluated by the e-BBPS system and endoscopists based on BBPS score. If both the endoscopists and e-BPPS system believed that the bowel preparation was sufficient, the patient immediately proceeded to a second colonoscopy. Otherwise, the patient underwent bowel preparation again. The differences in adenoma and polyp miss rate between the qualified group (e-BBPS system score ≤3) and the unqualified group (e-BBPS system score >3) were compared.Results:The adenoma miss rate in the qualified group was significantly lower than that in the unqualified group [26.72% (62/232) VS 42.53% (37/87), χ2=7.384， P=0.007, OR=2.029 (95% CI: 1.212-3.396)], and the polyp miss rate in the qualified group was significantly lower than that in the unqualified group [27.28% (195/702) VS 41.24% (113/274), χ2=16.539， P<0.001, OR=1.825 (95% CI: 1.363-2.443)]. Conclusion:The deep learning-based e-BBPS system demonstrates accuracy and reliability in bowel preparation assessment, offering potential to standardize the process of evaluating bowel preparation and reduce missed lesions.

Objective:To explore the clinical manifestations and genetic characteristics of a child with Leukoencephalopathy with ataxia (LKPAT) caused by a CLCN2 gene variant. Methods:A retrospective analysis was conducted on the clinical data of a child admitted to Hunan Children′s Hospital in June 2024 due to " intermittent convulsions for 13 days" . Peripheral blood samples were collected from the child and his parents for whole exome sequencing, followed by Sanger sequencing validation and pathogenicity analysis of candidate variants. Literature searches were performed using the keywords " CLCN2 gene" "chloride channel-2" "leukoencephalopathy with ataxia/LKPAT" "leukoencephalopathy" in both Chinese and English on CNKI, Wanfang, and PubMed databases. The search time was set from the establishment of the databases to July 31, 2024. Childhood-onset LKPAT literature was screened and analyzed. This study was approved by the Medical Ethics Committee of Hunan Children′s Hospital (Ethics No. HCHLL-2024-351). Results:① The child was a 7-month-and-26-day-old male infant born to consanguineous parents, presenting with epileptic seizures and borderline development. Cranial MRI revealed symmetrical long T 2 signal shadows in the posterior limb of the internal capsule, cerebral peduncle, pons, and middle peduncle of the cerebellum. Video electroencephalogram (EEG) showed an abnormal childhood EEG with one focal seizure. ② Whole exome sequencing revealed a homozygous c. 2201dup (p.Glu735Ter) variant in the CLCN2 gene of the child. Sanger sequencing confirmed that the variant was inherited from both parents. According to the guidelines of the American College of Medical Genetics and Genomics (ACMG) and the Association for Molecular Pathology (AMP), this variant was classified as pathogenic (PVS1+ PM3_Supporting+ PM2_Supporting). ③ A total of 8 relevant literature were retrieved, together with the present case, 16 childhood-onset LKPAT patients were cumulatively reported, which consisted of 9 males and 7 females. Twelve CLCN2 gene variants were involved, including 2 nonsense variants, 3 missense variants, 7 frameshifting variants, 2 c. 61dup variants, and 5 c.1709G>A variants. The initial symptoms of the 16 patients included headache, ataxia, epileptic seizures, spasticity, developmental delay, lower back pain, hearing impairment, and intention tremor. Three patients had the onset of the disease before the age of one, of which two had epileptic seizures as the initial symptom. Conclusion:The homozygous variant CLCN2: c. 2201dup (p.Glu735Ter) is considered the pathogenic cause of LKPAT in this child, marking the first childhood-onset case reported in China. Genetic testing has facilitated the diagnosis of childhood-onset LKPAT and expanded the spectrum of CLCN2 gene mutations.

Objective To explore the application of bundled nursing care for recurrent obstruc-tive esophageal cancer treated by photodynamic therapy.Methods Thirty patients with recurrent ob-structive esophageal cancer were administered with photosensitizer hematoporphyrin derivative injec-tion.After 24 hours,an optical fiber was introduced under endoscopic guidance,and 630 nm laser was used to irradiate the tumor locally.The degree of relief in dysphagia,improvement in perform-ance status,changes in body mass index,and treatment-related adverse reactions were recorded.Bundled nursing strategies were implemented,including preoperative assessment,education,prepara-tion,postoperative positioning,observation,prevention of complications,and light protection meas-ures.Results After treatment,the median diameter of the narrowest esophageal lesion was increased[(8.92±0.64)mm versus(4.77±0.60)mm],the Karnofsky Performance Status(KPS)score was improved[(77.69±5.99)versus(84.62±6.60)],BMI was increased[(17.17±1.66)kg/m2 ver-sus(18.08±1.60)kg/m2],and the Stooler dysphagia grade was decreased compared with treatment be-fore.The main treatment-related adverse reactions were retrosternal pain and fever.Conclusion Photo-dynamic therapy for recurrent obstructive esophageal cancer has a rapid onset of action and mild ad-verse reactions,and ensures the smooth implementation of PDT and patients'safety.

Objective:Measure the global longitudinal strain (GLS) of the left ventricle in trauma patients by beside speckle tracking echocardiography to explore the role of STE -GLS in evaluating left ventricular systolic function in trauma patients, and then explore the clinical value of GLS in judging the prognosis of trauma patients.Methods:Trauma patients admitted to intensive care unit from September 1, 2020 to April 1, 2021 with an Injury Severity Score (ISS) of ≥ 16 points. were consecutively enrolled. Moreover, those patients who met the following criteria were selected as the research subjects: aged between 18 and 80 years old, had no serious underlying diseases in the past, the time from trauma onset to admission was within 24 hours, and were able to complete an echocardiogram examination within 24 hours after the onset of the disease. Exclude patients who are unable to complete the ultrasound examination within 24 hours after the onset of the disease, or those with poor image quality, or those complicated with severe heart diseases and systemic comorbidities. The left ventricular global longitudinal strain (GLS) was measured by bedside speckle tracking echocardiography. According to the GLS values they were divided into abnormal group (GLS> -15%) and normal group (GLS≤ -15%). Independent sample t-tests and chi-square tests were applied to conduct a comparative analysis of the clinical characteristics between the two groups of patients. Furthermore, multiple linear regression analysis was conducted to explore the correlation between STE-GLS and the duration of intensive care unit stay.Results:A total of 32 trauma patients were eligible for this study. One patient was found to have abnormal left ventricular systolic function (LVEF<50%) detected by conventional echocardiography, however speckle tracking echocardiography detected decreased left ventricular systolic function (GLS> -15%) in 13 Patients. Multiple linear regression analysis showed that the global longitudinal strain of left ventricle and serum high sensitivity troponin I were independent risk factors affecting the time of intensive care in trauma patients.Conclusions:Speckle tracking echocardiography (STE) is more sensitive than traditional echocardiography and can detect left ventricular systolic dysfunction early. STE-GLS is an independent risk factor affecting hospitalization time of trauma patients in intensive care unit. Clinically, STE-GLS and serum Hs-TnI can be combined to determine the prognosis of trauma patients.

Objective:To explore the learning curve of primary urologists mastering Holmium laser enucleation of the prostate for the treatment of large volume benign prostatic hyperplasia (BPH).Methods:The clinical data of 92 patients with larger volume BPH who received HoLEP performed by a urologist in Beijing Friendship Hospital Pinggu Campus, Capital Medical University were retrospectively reviewed. 92 patients were divided into group A (1-23 cases, n=23), group B (24-46 cases, n=23), group C (47-69 cases, n=23), and group D (70-92 cases, n=23) based on the sequence of surgery. The clinical characteristics, including prostate volume, operation time, enucleation efficiency, indwelling catheter time, decrease value of hemoglobin, intraoperative blood transfusion, perioperative complications, and international prostate symptom score (IPSS), quality of life (QOL) score, Qmax, and postvoid residual urine (PVR) at 3 months postoperatively were compared between the four groups. Measurement data were expressed as mean ± standard deviation ( ± s), one-way analysis of variance was used for comparisons among multiple groups, and t-test was used for comparisons between two groups. Count data were expressed as the cases and percentage, and the Chi-square test was used for comparison between groups. Results:There were significant differences among the four groups in terms of operation time [(94.43±8.26) min, (86.39±5.89) min, (70.70±5.64) min, (64.70±4.23) min, P=0.001], enucleation efficiency [(0.90±0.08) mL/min, (1.01±0.07) mL/min, (1.23±0.12) mL/min, (1.34±0.12) mL/min, P=0.001], decrease value of hemoglobin [(25.98±1.39) g/L, (23.27±1.49) g/L, (20.03±1.07) g/L, (18.49±0.96) g/L, P=0.001] and indwelling catheter time [(5.91±1.54) d, (5.35±1.27) d, (3.39±0.72) d, (3.04±0.64) d, P=0.001]. Compared with group C and group D, the operation time was longer, the enucleation efficiency was lower, the decrease value of hemoglobin before and after the operation was higher, and the indwelling catheter time was longer, the above differences were all statistically significant ( P<0.05). However, there was no statistically significant difference between group A and group B, or group C and group D ( P>0.05). Among the 92 patients, only 3 patients received blood transfusion during operation, including 2 patients in group A and 1 patient in group B. 2 patients underwent surgical complications during the perioperative period. Among them, 1 patient suffered bladder wall injury due to improper operation of the tissue pulverizer in group A, and 1 patient developed prostatic capsule perforation in group B. Furthermore, after 56 cases of operation, a primary urologist can perform HoLEP surgery quickly and safely. Conclusion:The learning curve of a primary urologist mastering HoLEP for larger volume (≥ 80 mL) BPH was 56 procedures, and the operation efficiency and safety were significantly improved.
