Objective To establish quality evaluation method of Andrographis paniculata standard decoction by UPLC. Methods 21 batches of Andrographis paniculata standard decoctions were prepared according to the standardization method of TCM decoction pieces. The UPLC characteristic chromatograms analysis method was established. With andrographolide as a reference, quantitative analysis of multi-components by single marker （QAMS） was established for new neoandrographolide, 14 deoxyandrographolide and dehydrated andrographolide. The results were compared with the external standard method （ESM） to determine the accuracy of the method. Results Similarity Evaluation System for Chromatographic Fingerprint of TCM （2012 edition） was used to analyze and compare the characteristic chromatograms, and seven common peaks were determined and five were identified including luteolin-7-O-β-D-glucuronide, andrographolide, neoandrographolide, 14-deoxyandrographolide and dehydroandrographolide. The RSDs of content results of each component by QAMS and ESM were all within 3%. Conclusion The determination method was reliable and accurate, which could be used to reflect the intrinsic quality of Andrographis paniculata standard decoction comprehensively and provide the basis for the quality evaluation of Andrographis paniculata formula granules and other preparations.

Objective:To investigate the differences of the glymphatic system (GS) function between patients with mesial temporal lobe epilepsy with hippocampal sclerosis (mTLE-HS) and healthy controls and between different seizure types by using diffusion tensor imaging along perivascular space (DTI-ALPS), and to analyze the correlation between GS function and the course of disease, as well as the efficacy of predicting the surgical outcome.Methods:This study was a cross-sectional study. A total of 171 patients with mTLE-HS (mTLE-HS group) and 75 healthy volunteers (HC group) were retrospectively enrolled from July 2009 to July 2021 at Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University. The general information of all subjects, such as seizure type (partial seizure, secondary generalized seizure), surgical outcome, etc., was analyzed. The 3D magnetization prepared rapid gradient echo T 1WI and DTI sequence images were collected. The VBM analysis method was used to segment cerebrospinal fluid and calculate the volume. The ALPS index of the bilateral brain was calculated using the Atlas-based DTI-ALPS method. Independent sample t-test or paired t test were used to compare the ALPS index between the mTLE-HS group and HC group, and between patients with different seizure types. Pearson correlation analysis was used to analyze the correlation between bilateral ALPS index and disease duration in mTLE-HS group. The predictive value of the ALPS index for surgical outcomes was evaluated by receiver operating characteristics curve and area under the curve. Results:Among the 171 mTLE-HS patients, 98 patients were mTLE with left-side HS (mTLE-LHS) and 73 patients were mTLE with right-side HS (mTLE-RHS); 37 patients underwent surgical treatment, including 27 with good prognosis and 10 with poor prognosis. Compared with the HC group, the left-side ALPS index of mTLE-LHS and mTLE-RHS were both decreased ( P<0.05). The right-side ALPS index in mTLE-RHS was lower than that in the HC group ( P<0.001). There was no significant difference in the right-side ALPS index between mTLE-LHS and HC group ( P=0.080). The ALPS index on the affected side of patients with secondary generalized seizures was significantly lower than that of patients with only partial seizures (all P<0.05), but the difference in ALPS index on the healthy side was not statistically significant( P>0.05). The left-side and right-side ALPS index in mTLE-LHS were negatively correlated with disease duration ( r=-0.272, P=0.007; r=-0.307, P=0.002), but no significant correlation was found between the left-side or right-side ALPS index in mTLE-RHS (all P>0.05). The DTI-ALPS index on the affected side in mTLE-HS patients exhibited good diagnostic accuracy for surgical outcome classification, with an area under the curve of 0.778. Conclusions:The patients with mTLE-HS exhibit dysfunction of the GS, and the degree of impairment is related to the type of seizure and the course of epilepsy. The ALPS index, which characterizes the function of GS, demonstrates good diagnostic accuracy for classifying surgical outcomes.

Objective:To compare the clinical and radiological outcomes between the ankle dislocation exposure versus the traditional posterolateral approach exposure in the treatment of complex posterior ankle malunion.Methods:This retrospective study analyzed the 50 patients (50 feet) with posterior ankle malunion who had been treated at Department of Foot and Ankle Orthopedics, Foshan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Chinese Medicine from May 2015 to June 2023. This cohort included 18 males and 32 females, with an age of (46.2±12.0) years. The duration from injury to surgery averaged 7.0 (4.0, 12.2) months. The patients were divided into 2 groups based on the surgical exposure methods: an ankle dislocation group (22 cases) in which the posterior ankle malunion was exposed by ankle dislocation before reduction and fixation, and a traditional posterolateral approach group (28 cases) in which the posterior ankle malunion was exposed by the traditional posterolateral approach before reduction and fixation. Evaluation indices included operative time, ankle arthritis grading, incidence of complications, as well as pre-operative and last follow-up recordings of distal tibial articular angle and joint step-off, visual analogue scale (VAS) pain score, and ankle-hindfoot score of American Orthopaedic Foot and Ankle society (AOFAS).Results:There was no significant difference in the baseline data between the 2 groups, indicating comparability ( P>0.05). The average follow-up was (39.4±17.9) months. The operative time in the dislocation group [(95.8±9.9) min] was significantly shorter than that in the posterolateral approach group [(121.9±14.3) min] ( P<0.05). The step-off on the distal tibial articular surface at the last follow-up in the dislocation group [0.3 (0.0, 0.9) mm] was significantly lower than that in the posterolateral approach group [1.0 (0.3, 1.1) mm] ( P<0.05). The grading of ankle arthritis was significantly worse in the posterolateral approach group than that in the dislocation group ( P<0.05). There were no differences in distal tibial articular angle, VAS pain score, AOFAS ankle-hindfoot score, or postoperative complications between the 2 groups at the last follow-up ( P>0.05). Conclusions:Both ankle dislocation exposure and traditional posterolateral approach exposure yield satisfactory clinical and radiological outcomes in patients with complex posterior ankle malunion. However, the ankle dislocation exposure offers a novel method for direct visualization of the malunion on multiple planes, which is more advantageous for restoration of the anatomical consistency of the distal tibial articular surface.

Cell-free biosensors are detection tools that involve cell-free protein synthesis and consist of recognition elements and reporting elements.These biosensors offer several advantages,such as the ease of construction,a significant specificity and a high sensitivity.By overcoming the limitations associated with cell survival and cell membrane barriers,cell-free biosensors can considerably reduce response times.This article reviewed the recognition and reporting compo-nents of cell-free biosensors,summarizes recent research advancements in their applications to such spheres of public health as environmental monitoring and disease diagnosis,and explores the programmability and logical analysis capabili-ties of these biosensors.Future developments in this field are also predicted.
