Objective To observe the efficacy and safety of Morinda officinalis oligosaccharides in the continuation treatment of mild and moderate depression.Methods An open,single-arm,multi-center design was adopted in our study.Adult patients with mild and moderate depression who had received acute treatment of Morinda officinalis oligosaccharides were enrolled and continue to receive Morinda officinalis oligosaccharides capsules for 24 weeks,the dose remained unchanged during continuation treatment.The remission rate,recurrence rate,recurrence time,and the change from baseline to endpoint of Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),Clinical Global Impression-Severity(CGI-S)and Arizona Sexual Experience Scale(ASEX)were evaluated.The incidence of treatment-related adverse events was reported.Results The scores of HAMD-17 at baseline and after treatment were 6.60±1.87 and 5.85±4.18,scores of HAMA were 6.36±3.02 and 4.93±3.09,scores of CGI-S were 1.49±0.56 and 1.29±0.81,scores of ASEX were 15.92±4.72 and 15.57±5.26,with significant difference(P＜0.05).After continuation treatment,the remission rate was 54.59％(202 cases/370 cases),and the recurrence rate was 6.49％(24 cases/370 cases),the recurrence time was(64.67±42.47)days.The incidence of treatment-related adverse events was 15.35％(64 cases/417 cases).Conclusion Morinda officinalis oligosaccharides capsules can be effectively used for the continuation treatment of mild and moderate depression,and are well tolerated and safe.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To investigate the effect of transcranial direct current stimulation(tDCS)in the left posterior sylvia temporal-parietal association area on language function in patients with post-stroke conductive aphasia.Methods The post-stroke aphasia patients admitted to the Department of Rehabilitation Medicine,Xuanwu Hospital,Capital Medical University were prospectively included from June 2021 to April 2024.A self-cross randomized controlled trial was performed in this study.The patients enrolled were assessed as conductive aphasia by Western aphasia test kit diagnostic criteria.Twelve patients with post-stroke conductive aphasia were completely randomly divided into group A(treatment sequence:stage A—washout period—stage B)and group B(treatment sequence:stage B—washout period—stage A),with 6 cases in each group.Stage A performed true tDCS therapy combined with speech and language training,and stage B performed sham tDCS therapy combined with speech and language training.During washout period,only speech and language training was performed,and each stage was trained for 5 days.The tDCS anode is the stimulation electrode and is placed at the stimulation target.The cathode is the reference electrode and is placed on the right shoulder.The intensity of tDCS was 1.4 mA,the true stimulation was 20 min/time,and the sham stimulation stopped automatically after only 30 s/time,both twice/d,and a total of 10 times treatment were performed.Speech and language training was performed 30 min/time,2 times/d,a total of 10 times treatment.The function of rehearsal and picture naming(training item and non-training item)were examined before and after treatment of stage A and B immediately,and the difference of function scores of rehearsal and picture naming(training item and non-training item)before and after treatment of stage A and B were compared.Results(1)There were no significant differences in gender,age,course of disease and educational level between group A and group B(all P＞0.05).(2)Before and after washout period,there were no statistical significance in functional scores of rehearsal and picture naming(training items and non-training items)in both group A and group B(all P＞0.05).(3)There were no significant differences in functional scores of rehearsal and picture naming(training items and non-training items)between group A and group B before and after washout treatment(all P＞0.05).(4)Compared with the difference before and after treatment of stage B,the function scores difference before and after treatment of stage A in rehearsal function,picture naming(training item)and picture naming(non-training item)were higher([6.9±1.4]scores vs.[2.2±1.0]scores,t=9.604;[6.2±1.2]scores vs.[1.8±1.1]scores,t=9.277;[6.5±1.0]scores vs.[1.5±1.0]scores,t=12.247;all P＜0.01).Conclusions Preliminary analysis suggested that tDCS intervention in the brain tissue of the temporoparietal association area of the left posterior lateral cleft may help improve the rehearsal and picture naming(training and non-training items)ability in conductive aphasia patients after stroke.The sample size of this study is small,and the results need to be further explored.

Aim To investigate the mechanism of icar-itin(ICT)on D-galactose(D-gal)-induced TM4 ser-toli cell junctional function damage in vitro.Methods TM4 cells were divided into the normal control group and D-gal treatment group with different concentra-tions.The expression changes of TM 4 cell junction function-related proteins(ZO-1,Occludin,β-catenin and Cx43)and ERα/FAK signaling pathway-related proteins(ERα,FAK and pY397-FAK)were detected by Western blot.The concentration of ICT was screened by MTT method.TM4 cells were divided into normal control group,D-gal treatment group,and D-gal treatment+different concentrations of ICT group.The expression levels of the above proteins were detected by Western blot.Molecular docking was used to study the interaction between ERα and ICT,meanwhile predict the affinity between them.Finally,TM4 cells were di-vided into normal control group,D-gal treatment group,ERα inhibitor group,D-gal+ICT group,and ERα inhibitor+ICT group.The expression levels of the above proteins were detected by Western blot.Re-sults Compared with the normal control group,the ex-pression of junctional function-related proteins(ZO-1,Occludin,β-catenin and Cx43)and ERα/FAK signa-ling pathway-related proteins(ERα,FAK and pY397-FAK)were significantly down-regulated.After treat-ment with ICT,the expression of above proteins were significantly up-regulated.The docking results of ERα and ICT molecules revealed the formation of two hydro-gen bonds between Asp351 amino acid residue of ERα and ICT,with bond distances measuring 3.4? and 2.4?.Additionally,the docking binding energy be-tween them was found to be lower than-7 kcal·mol-1.After TM4 cells were treated with ERα inhibi-tor,the expression of above proteins and ERα/FAK signaling pathway-related proteins were significantly down-regulated,while the expression levels of the a-bove proteins did not change significantly after being given ICT protected group.Conclusions D-gal can cause damage to the junctional function of TM4 cells,and ICT can improve this damage,which may be related to the up-regulation of ERα/FAK signaling pathway.

This study investigated the mechanism of Danggui Shaoyao Powder(DSP) against mitophagy in rat model of Alzheimer's disease(AD) induced by streptozotocin(STZ) based on PTEN induced putative kinase 1(PINK1)-Parkin signaling pathway. The AD rat model was established by injecting STZ into the lateral ventricle, and the rats were divided into normal group, model group, DSP low-dose group(12 g·kg~(-1)·d~(-1)), DSP medium-dose group(24 g·kg~(-1)·d~(-1)), and DSP high-dose group(36 g·kg~(-1)·d~(-1)). Morris water maze test was used to detect the learning and memory function of the rats, and transmission electron microscopy and immunofluorescence were employed to detect mitophagy. The protein expression levels of PINK1, Parkin, LC3BⅠ/LC3BⅡ, and p62 were assayed by Western blot. Compared with the normal group, the model group showed a significant decrease in the learning and memory function(P<0.01), reduced protein expression of PINK1 and Parkin(P<0.05), increased protein expression of LC3BⅠ/LC3BⅡ and p62(P<0.05), and decreased occurrence of mitophagy(P<0.01). Compared with the model group, the DSP medium-and high-dose groups notably improved the learning and memory ability of AD rats, which mainly manifested as shortened escape latency, leng-thened time in target quadrants and elevated number of crossing the platform(P<0.05 or P<0.01), remarkably activated mitophagy(P<0.05), up-regulated the protein expression of PINK1 and Parkin, and down-regulated the protein expression of LC3BⅠ/LC3BⅡ and p62(P<0.05 or P<0.01). These results demonstrated that DSP might promote mitophagy mediated by PINK1-Parkin pathway to remove damaged mitochondria and improve mitochondrial function, thereby exerting a neuroprotective effect.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

Objective: To investigate the histological features and clinical manifestations in different types of cardiac amyloidosis to improve diagnostic accuracy. Methods: The histopathological features and clinical manifestations of 48 patients diagnosed with cardiac amyloidosis by Congo red stain and electron microscopy through endomyocardial biopsy were collected in West China Hospital of Sichuan University from January 2018 to December 2021. Immunohistochemical stains for immunoglobulin light chains (κ and λ) and transthyretin protein were carried out, and a review of literature was made. Results: The patients age ranged from 42 to 79 years (mean 56 years) and the male to female ratio was 1.1 to 1.0. The positive rate of endomyocardial biopsy was 97.9% (47/48), which was significantly higher than that of the abdominal wall fat (7/17). Congo red staining and electron microscopy were positive in 97.9% (47/48) and 93.5% (43/46), respectively. Immunohistochemical stains showed 32 cases (68.1%) were light chain type (AL-CA), including 31 cases of AL-λ type and 1 case of AL-κ type; 9 cases (19.1%) were transthyretin protein type (ATTR-CA); and 6 cases (12.8%) were not classified. There was no significant difference in the deposition pattern of amyloid between different types (P>0.05). Clinical data showed that ATTR-CA patients had less involvement of 2 or more organs and lower N-terminal pro-B-type natriuretic peptide (NT-proBNP) than the other type patients (P<0.05). The left ventricular stroke volume and right ventricular ejection fraction of ATTR-CA patients were better than the other patients (P<0.05). Follow-up data of 45 patients was obtained, and the overall mean survival time was 15.6±2.0 months. Univariate survival analysis showed that ATTR-CA patients had a better prognosis, while cardiac amyloidosis patients with higher cardiac function grade, NT-proBNP >6 000 ng/L, and troponin T >70 ng/L had a worse prognosis (P<0.05). Multivariate survival analysis showed that NT-proBNP and cardiac function grade were independent prognostic factors for cardiac amyloidosis patients. Conclusions: AL-λ is the most common type of cardiac amyloidosis in this group. Congo red staining combined with electron microscopy can significantly improve the diagnosis of cardiac amyloidosis. The clinical manifestations and prognosis of each type are different and can be classified based on immunostaining profile. However, there are still a few cases that cannot be typed; hence mass spectrometry is recommended if feasible.

Objective:To investigate the change of syndesmotic volume via CT scan in Danis-Weber B type ankle fracture, aiming to provide a non-invasive diagnostic method for Danis-Weber B type ankle fracture combined with syndesmotic injury.Methods:Retrospective analysis was performed on 48 patients with Danis-Weber B type ankle fractures in Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2018 to March 2022, including 30 males and 18 females, aging (43.71±19.41) years. Ankle CT scans and three-dimensional reconstructions were performed before surgery and at the last follow-up, measuring the syndesmotic volume between the tibiotalar joint and 1, 3 and 5 cm above the ankle and compared with each other. Intraoperative exploration was used as the gold standard for the syndesmotic injury. Based on the results of exploration of the syndesmotic injury, patients were divided into simple ankle fracture group (fracture group, 25 cases) and ankle fracture combined with syndesmotic injury group (fracture + ligament group, 23 cases). The sensitivity and specificity of this diagnostic method were statistically evaluated. The assessments at the last follow-up were performed to value the clinical effect of surgery. The metric data conforming to the normal distribution were expressed as mean ± standard deviation ( ± s), and the t-tests were used for comparison between groups. The measurement data of skewed distribution were expressed as quartile M( Q1, Q3), and nonparametric tests were used for intergroup comparison. Counting data were expressed as number of cases and percentage (%), and Chi-square test were used for intergroup comparison. Results:In the fracture group, there were no statistically significant differences of the syndesmotic volume at 1, 3, and 5 cm above the ankle joint before surgery and at the last follow-up ( P=0.219, 0.269, 0.103). On the contrary, the volume above were statistically significant in the fracture + ligament group ( P<0.001). There were statistically significant differences in syndesmotic volume between the two groups at 1, 3, and 5 cm above the ankle joint preoperatively ( P=0.005, 0.004, 0.038). By contrast, there were no statistical differences between the two groups postoperatively ( P=0.082, 0.155, 0.249). For the sensitivity and specificity of Danis-Weber B type ankle fractures combined with syndesmotic injury, they were 92% and 67% at 1 cm above the ankle joint, 69% and 87% at 3 cm above the ankle joint, and 62% and 87% at 5 cm above the ankle joint, respectively. The last follow-up clinical function score indicated a good surgical outcome. Conclusions:Volumetric measurement via CT scan is one of the diagnostic methods for evaluating Danis-Weber B type ankle fracture combined with syndesmotic injurys. Open resection internal fixation combined with elastic fixation of the ankle fracture combined with syndesmotic injurys can significantly reduce the lower tibiofibular volume, and the efficacy is definite.
