ObjectiveAge-related macular degeneration （AMD） is one of the leading causes of low vision and blindness in people over 50 years old， and dry AMD （dAMD） is one type for which there is currently no clear treatment. On the basis of the diagnosis and clinical characteristics of dAMD in traditional Chinese and Western medicine， this paper evaluated the fitting degrees of existing animal models of dAMD with clinical characteristics according to the evaluation methods of animal models， and put forward suggestions and prospects. MethodsLiterature on animal models of dAMD was searched against database， and the characteristics of the models were assigned according to the diagnosis criteria of diseases and syndromes of traditional Chinese and Western medicine， and the fitting degrees of the models with clinical characteristics were analyzed and evaluated. ResultsAt present， the animal models of dAMD are mainly established targeting complement factors， chemokines， oxidative damage， lipid/glucose metabolism， and natural strains. Most of the models can simulate the major pathological changes of dAMD， showing the fitting degree of 25%-50% with clinical characteristics in Western medicine. However， the evaluation of traditional Chinese medicine （TCM） syndromes， especially the evaluation of secondary syndromes， is missing， and the models present low fitting degrees with the clinical characteristics in TCM. ConclusionExisting animal models of dAMD are mostly established under the guidance of Western diagnostic standards， which reproduce the main disease characteristics of Western medicine and lack observation of TCM syndromes. Future studies can pay attention to the intervention factors and evaluation systems of spleen deficiency Qi deficiency and liver-kidney Yin deficiency syndrome and build the animal model of dAMD with integration of disease and syndrome based on clinical characteristics of traditional Chinese and Western medicine.

Fused teeth are usually formed by the partial or complete fusion of two normal tooth germs during the development process and belong to dental developmental abnormalities. Fused teeth are relatively rare clinically, and those occurring in the posterior tooth area are even rarer. This article reports a case of fused teeth between the first permanent molar and the second permanent molar in the right mandible. This fused tooth had a complex root canal anatomical structure (seven root canals). The number and location of the root canals were analyzed by cone beam computed tomography, and root canal treatment was successfully completed with the assistance of microscope.

Objective:To investigate the current status of psychosocial adaptation in young and middle-aged patients after colorectal cancer surgery and to explore its influencing factors, providing a basis for the development of targeted interventions.Methods:A total of 200 postoperative young and middle-aged colorectal cancer patients undergoing follow-up at the outpatient department of Shanxi Cancer Hospital from June 2023 to March 2024 were selected by convenience sampling. Data were collected using a general demographic questionnaire, the Self-Report Psychosocial Adjustment to Illness Scale (PAIS-SR), the Family APGAR Index Questionnaire, and the Simplified Ways of Coping Questionnaire (SWCQ). Multiple linear regression analysis was performed to identify factors influencing psychosocial adaptation.Results:A total of 200 questionnaires were distributed, and 191 valid responses were collected, yielding a valid response rate of 95.5%. The total PAIS-SR score of participants was (57.91±23.45). Multiple linear regression analysis revealed that education level, self-perceived economic status, employment status, presence of a stoma, time since surgery, family care, and positive coping style were statistically significant influencing factors ( P<0.05), explaining 46.4% of the variance in psychosocial adaptation. Conclusions:Healthcare providers should pay particular attention to patients with lower educational levels, poor self-perceived economic conditions, unemployment, a stoma, and shorter postoperative duration. Enhancing family care—starting with patient caregivers—and encouraging the use of positive psychological interventions to foster active coping strategies may help improve psychosocial adaptation in young and middle-aged colorectal cancer patients.

Objective To compare the therapeutic effects of laparoscopic transabdominal preperitoneal repair(TAPP)and Bassini herniorrhaphy in the treatment of inguinal hernia.Methods 107 patients with inguinal hernia from January 2021 to December 2024 were selected and divided into the Bassini group(53 cases were repaired by Bassini herniorrhaphy)and the TAPP group(54 cases were repaired by TAPP)by random number table method.The surgical-related indicators,pain degree,stress index levels,quality of life,rehabilitation effect and incidence of complications of the two groups of patients were compared.Results The operation time of the Bassini group was significantly shorter than that of the TAPP group,the intraoperative blood loss was significantly more than that in the TAPP group,and the hospital stay was significantly longer than that in the TAPP group,the differences were statistically significant(P<0.05).The visual analogue scale(VAS)score of the two groups of patients after surgery showed a trend of first increasing and then decreasing.The VAS scores of the TAPP group at 3 and 7 days after surgery were significantly lower than those of the Bassini group,and the differences were statistically significant(P<0.05).The levels of cortisol and norepinephrine in both groups of patients 3 days after the operation were significantly higher than those before the operation,and the Bassini group was significantly higher than the TAPP group,the differences were statistically significant(P<0.05).The total effective rate of the TAPP group was 98.15%,significantly higher than that of the Bassini group(83.02%),and the difference was statistically significant(P<0.05).The Short Form 36(SF-36)score of the two groups of patients one month after the operation was significantly higher than that before the operation,and the TAPP group was significantly higher than the Bassini group,the differences were statistically significant(P<0.05).The incidence of complications in the TAPP group was 3.70%,significantly lower than 18.87%in the Bassini group,and the difference was statistically significant(P<0.05).Conclusion Compared with Bassini herniorrhaphy,TAPP can effectively shorten the hospital stay,reduce intraoperative blood loss,lower postoperative pain and stress response,improve the postoperative quality of life of patients,enhance rehabilitation effect and reduce the incidence of complications.It is worthy of clinical promotion and application.

Objective:To evaluate the alveolar ridge preservation effect of immediate implantation at extraction site with the im-proved CBCT measuring method.Methods:Eighty patients with extraction site were divided into test group A,B,C and control group.The patients were treated by means of immediate implant placement combined with large flap surgery,guided bone regener-ation(GBR)using mass Bio-Oss bone particles in the group A(the thickness of facial bone wall＜1 mm);The patients were trea-ted by means of immediate implant placement combined without flap surgery and bone graft in the group B(the thickness of facial bone wall ≥1 mm and＜2 mm)and C(the thickness of facial bone wall ≥2 mm),the CGF was implanted in the jumping space only when the thickness of jumping space was＞2 mm.In the control group,the alveolar sockets healed naturally without any in-tervention or treatment.CBCT was taken before surgery,immediately after surgery,and 6 months after surgery to evaluate the height and width of alveolar bone,the thickness of facial bone wall and jumping space.Results:The reduction of alveolar ridge height in group A,B,C and control group was(0.41±0.13,0.94±0.18,0.59±0.12,1.31±0.19)mm,The reduction of alveolar ridge width in group A,B,C and control group was(0.93±0.10,1.48±0.21,1.12±0.17,1.66±0.16)mum.The re-sults of four groups were statistically different(F=177.0,P＜0.001;F=125.3,P＜0.001).The alveolar ridge thickness of facial bone wall in group A,B,C and con-trol group was(0.98±0.25,2.39±0.28)mm,(1.43±0.52,2.10±0.33)mm,(2.17±0.41,2.79±0.27)mm before surgery and six months after immediate implantation.The results of each group were statistically different between before surgery and six months after immediate implantation(t=16.45,P＜0.001;t=7.357,P＜0.001;t=5.488,P＜0.001).Patients in three test groups had the thickness of jumping space＞2 mm and ≤2 mm,and the reduction of alveolar ridge width was(0.78±0.18,0.88±0.17)mm.The results were statistically different(t=17.18,P=0.018).Conclusion:The alveolar ridge preservation was obtained by means of immediate implant placement combined with large flap surgery,guided bone regeneration(GBR)using mass Bio-Oss bone particles at extraction site with the thickness of facial bone wall＜1 mm;The alveolar ridge preservation was obtained without flap surgery and GBR at extraction site with the thickness of facial bone wall≥1 mm.The preservation of soft and hard tissue was better in the axial palatal side of immediate implantation with the thickness of jumping space＞2 mm than that with the thickness of jumping space≤2 mm.

Purpose To evaluate the predictive value of left atrial appendage(LAA)morphological assessment by preoperative left atrial CT imaging in the risk of peri-device leak(PDL)after left atrial appendage occlusion(LAAO)in atrial fibrillation.Materials and Methods Seventy-one patients with atrial fibrillation who successfully underwent LAAO in Nanchong Central Hospital from January 2020 to February 2024 were retrospectively analyzed.According to the results of left atrial CT imaging after LAAO,all patients were divided into the PDL group(n=26)and the non-PDL group(n=45).The long diameter,short diameter,long diameter/short diameter ratio,area,perimeter of both the LAA orifice and landing area,and LAA length and LAA depth were compared between the two groups.Univariate and multivariate Logistic regression analysis were used to explore the risk factors leading to the differences between the two groups.Results The long diameter,long diameter/short diameter ratio,area,perimeter of both the LAA orifice and landing area in the PDL group were statistically higher than those in the non-PDL group(t/Z=4.952,-5.570,-2.912,3.191,6.757,-6.462,-3.318,3.733,all P<0.05).The LAA orifice short diameter,LAA length,LAA depth and the short diameter of landing area in the PDL group were higher than those in the non-PDL group,but there were no statistically significant differences between the two groups(t/Z=-1.773,1.765,1.509,-1.415,all P>0.05).Univariate Logistic regression analysis showed that the long diameter,long diameter/short diameter ratio,area and perimeter of LAA orifice and landing area before operation were correlated with postoperative PDL(P<0.05).Multivariate Logistic regression analysis showed that,the long diameter/short diameter ratio of LAA landing area was an independent risk factor for postoperative PDL.Conclusion Preoperative evaluation of the morphology of LAA orifice and landing zone by left atrial CT imaging can predict the occurrence of PDL after LAAO in atrial fibrillation in advance.When the long/short diameter of the landing area is large,it is necessary to be highly alert to the occurrence of PDL,which provides a basis for selecting and customizing the occluder before LAAO in patients with atrial fibrillation.

The female reproductive system is essential for sustaining reproductive endocrine homeostasis,however,its vulnerability to various endogenous and exogenous insults,including pathological conditions,pharmacological agents,genetic predispositions,and environmental factors,often results in compromised fertility.The existing protective approaches(including surgical interventions,hormonal replacement therapies,and assisted reproductive techniques)are constrained by several limitations,such as adverse therapeutic effects,technical complexities,and their incapacity to reverse ovarian senescence.Artemisinin and its derivatives(ARTs),characterized by their unique endoperoxide bridge configuration,have exhibited outstanding therapeutic performance across multiple domains including malaria treatment,anticancer therapy,inflammation modulation,and parasitic infection control.Emerging research has identified their novel protective capabilities against various reproductive system pathologies.This comprehensive review systematically elucidates the molecular mechanisms underlying artemisinin-based interventions in reproductive pathologies and evaluates their clinical translation prospects,thereby proposing innovative strategies for the development of next-generation fertility-protective agents with enhanced safety and efficacy profiles.

BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.
