The deficiency of fingers due to various reasons leads to a certain degree of loss of full or part hand functions. Physical and mental health of patients are seriously affected, and patients have varying degrees of reduced quality of life. Prosthesis fingers play an important role in completing the body shape and enhancing patients’ self-confidence and self-esteem. However, how to make prosthesis fingers perform coordinated movements and restore complete functions is a crucial problem that urgently needs to be solved. This paper reviews the methods of brain-computer interface controlled fine finger movements and elaborates on the origin, current situation, and advancements of the development of this technology, laying a foundation for subsequent research, with the expectation of helping patients solve the problems arising from the insufficiency or absence of finger functions.

Objective:To explore the clinical effect of Triangle hierarchical management in patients with acute non-ST-segment elevation myocardial infarction(NSTEMI)after percutaneous coronary intervention(PCI).Methods:A total of 107 NSTEMI patients who underwent PCI in our hospital from Jan 2019 to Dec 2022 were selected.Ac-cording to the random number table method,patients were divided into control group(n=53)and observation group(n=54).Patients in the control group received routine rehabilitation training,while observation group re-ceived Triangle hierarchical management based on control group,both groups were intervened for 6 months.Car-diopulmonary function indexes,scores of myocardial infarction dimensional assessment scale(MIDAS)and general self-efficacy scale(GSES)before and after intervention,and incidence of adverse events during follow-up were compared between two groups.Results:During study period,two cases were lost in the control group and one case withdrew in the observation group,with 51 and 53 cases finally enrolled in each group,respectively.Compared with the control group after intervention,there were significant rise in forced expiratory volume in one second(FEV1)[(2.98±0.27)L vs.(3.30±0.35)L],FEV1/forced vital capacity(FVC)[(72.65±4.31)％vs.(77.06±3.95)％]and GSES score[(18.53±2.63)points vs.(26.89±3.19)points],and significant reduction in MIDAS total score[(65.53±4.86)points vs.(56.26±4.38)points]in observation group(P＜0.001 all).There was no significant difference in the incidence rate of adverse events between control group and observation group during fol-low-up(13.73％vs.7.55％,P=0.306).Conclusion:Triangle hierarchical management may significantly improve lung function,self-efficacy and quality of life with high safety in patients with acute non-ST-segment elevation myocardial infarction after PCI,suggesting that it worths promoting in clinical practice.

Several mitochondrial dysfunctions in obesity and diabetes include impaired mitochondrial membrane potential, excessive mitochondrial reactive oxygen species generation, reduced mitochondrial DNA, increased mitochondrial Ca2+ flux, and mitochondrial dynamics disorders. Mitophagy, specialized autophagy, is responsible for clearing dysfunctional mitochondria in physiological and pathological conditions. As a paradox, inhibition and activation of mitophagy have been observed in obesity and diabetes-related heart disorders, with both exerting bidirectional effects. Suppressed mitophagy is beneficial to mitochondrial homeostasis, also known as benign mitophagy. On the contrary, in most cases, excessive mitophagy is harmful to dysfunctional mitochondria elimination and thus is defined as detrimental mitophagy. In obesity and diabetes, two classical pathways appear to regulate mitophagy, including PTEN-induced putative kinase 1 (PINK1)/Parkin-dependent mitophagy and receptors/adapters-dependent mitophagy. After the pharmacologic interventions of mitophagy, mitochondrial morphology and function have been restored, and cell viability has been further improved. Herein, we summarize the mitochondrial dysfunction and mitophagy alterations in obesity and diabetes, as well as the underlying upstream mechanisms, in order to provide novel therapeutic strategies for the obesity and diabetes-related heart disorders.

Strigolactones(SLs) are a class of sesquiterpenoids derived from the carotenoid biosynthesis pathway with the core carbon skeleton consisting of tricyclic lactone(ABC tricyclic ring) and α,β-unsaturated furan ring(D ring). SLs are widely distributed in higher plants and are symbiotic signals between plants and Arbuscular mycorrhiza(AM), which play key roles in the evolution of plant colonizing terrestrial habitats. As a new type of plant hormone, SLs possess such important biological functions as inhibiting shoot branching(tillers), regulating root architecture, promoting secondary growth, and improving plant stress resistance. Therefore, SLs have attracted wide attention. The biological functions of SLs are not only closely related to the formation of "excellent shape and quality" of Chinese medicinal materials but also have important practical significance for the production of high-quality medicinal materials. However, SLs have been currently widely studied in model plants and crops such as Oryza sativa and Arabidopsis thaliana, and few related studies have been reported on SLs in medicinal plants, which need to be strengthened. This review focused on the latest research progress in the isolation and identification, biological and artificial synthesis pathways, biosynthesis sites and transport modes, signal transduction pathways and mechanisms, and biological functions of SLs, and prospected the research on the regulation mechanism of SLs in the growth and development of medicinal plants and their related application on targeted regulation of Chinese herbal medicine production, which is expected to provide some references for the in-depth research on SLs in the field of Chinese medicinal resources.

OBJECTIVE: This study was conducted to explore the mechanism of intestinal inflammation and barrier repair in Crohn's disease (CD) regulated by moxibustion through bile acid (BA) enterohepatic circulation and intestinal farnesoid X receptor (FXR). METHODS: Sprague-Dawley rats were randomly divided into control group, CD model group, mild moxibustion group and herb-partitioned moxibustion group. CD model rats induced by 2,4,6-trinitrobenzene sulfonic acid were treated with mild moxibustion or herb-partitioned moxibustion at Tianshu (ST25) and Qihai (CV6). The changes in CD symptoms were rated according to the disease activity index score, the serum and colon tissues of rats were collected, and the pathological changes in colon tissues were observed via histopathology. Western blot, immunohistochemistry (IHC) and immunofluorescence were used to evaluate the improvement of moxibustion on intestinal inflammation and mucosal barrier in CD by the BA-FXR pathway. RESULTS: Mild moxibustion and herb-partitioned moxibustion improved the symptoms of CD, inhibited inflammation and repaired mucosal damage to the colon in CD rats. Meanwhile, moxibustion could improve the abnormal expression of BA in the colon, liver and serum, downregulate the expression of interferon-γ and upregulate the expression of FXR mRNA, and inhibit Toll-like receptor 4 (TLR4) and myeloid differentiation factor 88 (MyD88) mRNA. The IHC results showed that moxibustion could upregulate the expression of FXR and mucin2 and inhibit TLR4 expression. Western blot showed that moxibustion inhibited the protein expression of TLR4 and MyD88 and upregulated the expression of FXR. Immunofluorescence image analysis showed that moxibustion increased the colocalization sites and intensity of FXR with TLR4 or nuclear factor-κB p65. In particular, herb-partitioned moxibustion has more advantages in improving BA and upregulating FXR and TLR4 in the colon. CONCLUSION Mild moxibustion and herb-partitioned moxibustion can improve CD by regulating the enterohepatic circulation stability of BA, activating colonic FXR, regulating the TLR4/MyD88 pathway, inhibiting intestinal inflammation and repairing the intestinal mucosal barrier. Herb-partitioned moxibustion seems to have more advantages in regulating BA enterohepatic circulation and FXR activation.

OBJECTIVE: To establish the fixation model of anterior cervical transpedicular system (ACTPS) after subtotal resection of two segments of lower cervical spine(C₃-C₇) in order to provide a finite element modeling method for anterior cervical reconstruction. METHODS: The CT data of the cervical segment (C₁-T₁) of a 30-year-old adult healthy male volunteer was collected. Used Mimics 10.0, Rapidform XOR3, HyperMesh 10.0, CATIA5V19 and ANSYS 14.0 to establish the three-dimensional nonlinear complete model of lower cervical spine(C₃-C₇) as the intact group. The number of units and nodes of the complete model were recorded. After the effectiveness of the complete model was verified, the C₅ and C₆ vertebral subtotal resection was performed, and the ACTPS model was established as the ACTPS group. The axial force of 75 N and moment couple of 1N·m was loaded on the upper surface of C₃ in intact group and ACTPS group, the range of motion(ROM)and stress distribution in states of flexion extension, lateral flexion, rotation was compared between two groups. RESULTS: There were 85 832 elements and 23 612 nodes in the complete model of lower cervical spine(C₃-C₇) which was established in this experiment. The stress distribution of ACTPS internal fixation model was relatively uniform. Comparing with the intact group, the overall range of motion in ACTPS group was decreased in flexion extension, lateral flexion and rotation directions, and the corresponding compensation of adjacent C_3,4 segment was increased slightly. CONCLUSION The stress distribution of ACTPS fixation system is uniform, there is no stress concentration area at the joint of screw and titanium plate, and the fracture risk of internal fixation is low. It is suitable for stability reconstruction after anterior decompression of two or more cervical segments.

OBJECTIVE: To compare accuracy of anterior cervical pedicle screws between assist of rapid prototyping 3D guide plate and free-hand insertion, and evaluate the safety of two methods. METHODS: Eight adult cervical cadaver specimens after formaldehyde immersion, including 4 males and 4 females, aged 32 to 65(40.3±5.6) years old. After X-ray examination to exclude bone damage and deformity, 4 of them (3D guide plate group) randomly selected were for CT scan to obtain DICOM format data, and the data was imported into Mimics software for model, designed the ideal entry point and nail path for anterior cervicaltranspedicular screw (ATPS). After obtaining the personalized guide plate of the nail channel, it was exported as STL data, and the individual guide plate was printed by rapid prototyping and 3D printing technology. In turn, with the assistance of 3D guide plates, one-to-one personalized ATPS screws were placed on the four lower cervical cadaver specimens. Another 4 (free-hand group) lower cervical cadaver specimens were implanted with ATPS screws using free-hand technique. All specimens were performed CT thin-layer scanning and three-dimensional reconstruction after operation. The Tomasino method was used to evaluate the safety of the screws on the CT cross-sectional and sagittal images, to determine whether there was a cortical puncture of the lower and inner edges of the pedicle. According to the CT rating results, gradeⅠandⅡwere safe, and grade Ⅲ- Ⅴ were dangerous.And the accuracy of screws was recorded and analyzed between two groups. RESULTS: Two screws were inserted in each segment from C CONCLUSION The 3D printing rapid prototyping guide plate assisted insertion of the anterior cervical pedicle screw can significantly improve the accuracy and safety, and provide a theoretical basis for further clinical application.

OBJECTIVE: To observe the effect of acupuncture-moxibustion on negative emotions and plasma tryptophan (Trip)-kynurenine (Kyn) metabolism in the patients with Crohn's disease (CD) at the mild and moderate active stage. METHODS: A total of 66 CD patients were randomized into an observation group (33 cases, 1 case dropped off) and a control group (33 cases, 2 cases dropped off). In the observation group, acupuncture was applied in combination with moxibustion. In the control group, the sham-acupuncture was used in combination with sham-moxibustion. In both of the observation group and the control group, acupuncture was applied to Zhongwan (CV 12), Shangjuxu (ST 37), Sanyinjiao (SP 6), Gongsun (SP 4), Hegu (LI 4), Quchi (LI 11), Taixi (KI 3) and Taichong (LR 3), and moxibustion was applied to Tianshu (ST 25) and Zusanli (ST 36). The treatment was given once every two days, 3 times a week, totally for 12 weeks. Separately, before and after treatment, the score of the hospital anxiety-depression scale (HADS) and the score of intestinal core symptoms (degree of abdominal pain and frequency of diarrhea) were observed in the patients of the two groups. The concentration of plasma indoleamine 2,3-dioxygenase 1 (IDO1) and the ratios of Kyn/Trp, QuinA/Kyn, KynA/Kyn and KynA/QuinA were compared between the two groups. RESULTS: Compared with before treatment, the scores of HADS-A and HADS-D in the observation group and the score of HADS-A in the control group were all reduced after treatment ( CONCLUSION Acupuncture and moxibustion relieve the negative emotions of anxiety and depression in CD patients at mild and moderate active stage, which is probably related to the regulation of plasma Trp-Kyn metabolic pathway.

Objective:To explore the seizure recurrence and prognosis of epilepsy in relapse after anti-epileptic drugs (AEDs) withdrawal, and the influencing factors for these conditions.Methods:From December 2009 to August 2018, patients from the Affiliated Brain Hospital of Nanjing Medical University who relapsed after AEDs withdrawal were collected and followed up for at least 18 months. The seizure recurrence and prognosis of these patients were prospectively observed. The Kaplan-Meier method was used for survival analysis. The associated risk factors of the second relapse in the enrolled patients were analyzed by multivariate Cox analysis. The included patients were divided into good prognosis group and poor prognosis group according to whether they had achieved seizure freedom for at least one year after the first relapse. A multivariate Cox regression model was used to analyze the independent risk factors affecting their prognosis.Results:A total of 56 patients with epilepsy in relapse after AEDS withdrawal were collected. The average follow-up period was 46.23 months (18-120 months) from the initial time of seizure recurrence, and 21 patients (37.5%) had the second seizure recurrence. The relapsing risk in patients who continued to be observed without adding AEDs was higher than those who were treated immediately with drugs [9/16 vs 30.0% (12/40)], but without statistically significant difference (χ2=2.220, P=0.071). The results of univariate analysis showed that focal seizures, seizure frequency more than once per month before remission and poly-drug therapy before AEDs withdrawal were associated with high risk of the second relapse. Poly-drug therapy was an independent risk factor for the second relapse by multivariate Cox analysis ( HR=3.383, 95% CI 1.257-9.105). Of the 56 patients with epilepsy in relapse after AEDs withdrawal, 47 patients (83.9%) had a good prognosis without seizure for at least one year, and of 33 patients who were followed up for three years or more, 26 (78.8%) had no seizure for at least two years. Between the group retreated immediately after the first recurrence and the group without immediate treatment [87.5% (35/40) vs 12/16],there were no statistically significant differences on the proportions of good prognosis (χ2=2.333, P=0.258). Univariate analysis showed that the course of epilepsy>6 months before initial treatment, the frequency of seizures>1/month before remission, symptomatic epilepsy and poly-drug therapy were associated with the poor prognosis. However, none of independent risk factors was found for the poor prognosis through the multivariate analysis. Conclusions:The prognosis of patients with epilepsy in relapse after AEDs withdrawal is well, and about 2/3 patients with epilepsy in relapse after AEDs withdrawal have no more seizure recurrences. The poly-drug therapy before AEDs withdrawal may be an independent risk factor for the second seizure relapse.
