Facial anthropometry has profound importance in clinical diagnosis and the recognition of abnormal facial features. With the development of anthropometry, facial anthropometry has emerged as an independent research field and is widely applied in disciplines such as plastic surgery and cranio-maxillofacial surgery. This paper reviews the evolution of facial anthropometry and discusses its future trends in the context of artificial intelligence (AI). Currently, 3D facial imaging technology can accurately capture and reconstruct the three-dimensional morphology of facial soft tissues, and enhance the precision and objectivity of measurements, thus becoming the new "gold standard" for facial anthropometry. It not only provides reference for disease diagnosis and surgical planning but also plays a crucial role in evaluating cosmetic outcomes and aging research. In recent years, AI technology has developed rapidly, enabling direct recognition of abnormal facial features. Although facial recognition systems based on two-dimensional images are relatively mature, they have to struggle to fully capture facial features as they are limited by the dimensionality of information. While three-dimensional image-based recognition boasts high accuracy, it faces challenges in the recognition and classification of abnormal facial features due to limitations in the number of training samples. The integration of AI and facial anthropometry has effectively promoted automatic recognition technology for facial landmarks, thus providing more precise and interpretable methods for assessing disease-related facial features. Future research should focus on building reliable three-dimensional facial databases to further improve the accuracy of facial recognition. Additionally, developing facial recognition systems based on small sample sizes is necessary to provide robust support for the recognition of facial features associated with rare and special diseases.

Epilepsy is one of the five major neuropsychiatric diseases on which the World Health Organization focuses. New treatment methods are emerging, such as neuromodulation and radiofrequency ablation to remove lesions and precise treatment for gene mutation. However, antiepileptic drug therapy is still the first choice mostly. Since potassium bromide was applicated in epilepsy in 1857, which opened the prelude to the development of modern antiepileptic drugs, more than 20 kinds of antiepileptic drugs have been used in clinical practice. This article reviews the present status and future development of antiepileptic drugs at home and abroad.

Objective To study the synergistic effect of NKX6. 1 and PDX1 in inducing differentiation of fetal liver-derived mesenchymal stem cells(FL-MSCs) into the pancreatic B cells and to explore the underlying mechanisms, so as to obtain enough islet-like body for transplantation. Methods Recombinant adenovirus vector harboring both PDX1 and NKX6. 1 genes was constructed, and the vector was used to infect FL-MSCs. Then a series of cytokines were used to induce the differentiation of infected FL-MSCs into pancreatic B cells. The expressions of PDX1, NKX6.1 gene, transcription factors NGN3, NeuroDl/Beta2, MafA as well as C-peptide were examined. Results PDX1 and NKX6. 1 were detected in FL-MSCs cells 24 h after infection; cells began to express NGN3, NeuroDl, and MafA and stably expressed pancreatic B cell related factors including insulin after induction. The expression of these molecules was in a certain order. Conclusion PDX1, NKX6. 1 combined with a series of cytokines can effectively induce FL-MSCs to differentiate into pancreatic islet B cells in vitro, which might be through activation of transcription factors NGN3, NeuroDl, and MafA in turn, inducing FL-MSCs to differentiate towards endocrine precursor cells, B endocrine precursor cells and B cells in turn.

Ultrasmall superparamagnetic iron oxide (USPIO), as the contrast agent of MRI, possesses two major properties: long half time in the plasma and specific binding with macrophages. Compared with gadolinium, widely-used in clinic presently, USPIO has its unique advantages in diagnosis of central nervous system diseases, though which still need further clinical verification. This article reviews the application of USPIO in MRI diagnosis of some central nervous system diseases.

AIM: To study the inhibitory effect of captopril on retinal neovascularization (RNV).METHODS: Sixty seven-day-old mice were randomly divided into treated group and control group with thirty mice in each group. These mice were exposed to 750 50mL/L oxygen for 5 days and then to room air.The treated group had been injected captopril (2.7mL/kg), while control group had been injected 9g/L sodium chloride (2.7mL/kg) by intravitreal for 5 days.The mice were sacrificed at the 17th day after birth and the eyes were enucleated. Adenosine diphosphate-ase(ADPase) stained retina flat-mounts was performed to assess the retinal vascular profiles, Hematoxylin Eosin (HE)staining method was applied to count the number of new vascular cell nuclei and the expression of matrix metalloproteinase-2(MMP-2)and pigment epithelium derived factor (PEDF)was detected by immunohistochemical method.RESULTS: Comparing with control group,regular distributions and good branch and reduced density of RNV were observed in the treated group. The number of nucleus of new vessels vascular endothelial cells breaking through the internal limiting membrane was less in the treated group than in the control group (P<0.05). Stain of retinal MMP-2 was weaker in the treated group than in the control group and stain of retinal PEDF was stronger in the treated group than in the control group.CONCLUSION: Intravitreal injection of captopril (2.7mL/kg) may block the RNV in the oxygen-induced mouse model and may provide an effective method for prevent-ing RNV.

Periodontitis is a chronic infective disease characterized as the destruction of the supporting tissues of the teeth. Bone marrow mesenchymal stem cells, which are ideal adult stem cells for the regeneration of supporting tissues, may play important roles in restoring the structure and function of the periodontium and in promoting the treatment of periodontal disease. As a consequence, the characteristics, especially osteogenic differentiation mechanism, of these stem cells have been extensively investigated. The regulation of the physiological behavior of these stem cells is associated with BMAL1 gene. This gene is a potential treatment target for periodontal disease, although the specific mechanism remains inconclusive. This study aimed to describe the characteristics of BMAL1 gene and its ability to regulate the osteogenic differentiation of stem cells.

OBJECTIVETo investigate clinical curative effects of gluteal muscle contracture release combined with insertion of gluteus maximus tendo-chilles lengthening with Z-shaped in treating severe gluteal muscles contracture.

METHODSFrom 2006 May to 2011 May, 20 patients (35 sides) with severe gluteal muscle contracture were collected, including 12 males and 8 females, aged from 8 to 34 years old with an average of 13 years old; the courses of disease ranged from 3 to 21 years. All patients manifested abnormal gait at different degree, knees close together cannot squat,positive syndrome of Ober, positive test of alice leg. Gluteus contracture fascia release were performed firstly in operation, then insertion of tendo-chilles lengthening with Z-shaped were carried out. Preoperative and postoperative gait, and knee flexion hip extensor squat test, cross leg test, adduction and internal rotary activity of hip joint, stretch strength and motor ability after hip abduction were observed and compared.

RESULTSTwenty patients were followed up for 1 to 5 years. Gluteus maximus were released thoroughly, and snapping hip was disappeared, Ober syndrome were negative. There was significant differences in knee flexion hip extensor squat test, adduction and internal rotary activity of hip joint,stretch before and after operation (P<0.01). Gluteus muscle strength was protected,stretch strength and motor ability of hip joint were recovered well. Among them,31 cases got excellent results and 4 good.

CONCLUSIONFor severe gluteal muscles contracture,insertion of gluteus maximus tendo-chilles lengthening with Z-shaped performed after gluteus contracture fascia release could release gluteal muscle contracture to the greatest extent and obtain postoperative curative effect without resection of normal hip muscle fibers and destroy joint capsule.
