Objective:To explore the effects of essential tremor(ET)on the mitochondrial morphology of GABAer-gic and glutamatergic neurons in the inferior olive(IO).Methods:The ET mouse model was established via intraper-itoneal injection of harmaline.Twelve 8-week-old male C57BL/6J mice were randomly divided into saline control group and harmaline treatment group(HA).Behavioral tests,including open field test,rotarod test,balance beam test,and tremor scoring,were conducted to assess the behavior of mice.Using genetic engineering technology and the CRISPR/Cas9 system,we designed and generated 6 male GAD2-Mito-GFP mice and 6 male VGLUT2-Mito-GFP mice,all being 8-week-old.The mice of each transgenic line were randomly divided into Control and HA group.Immunofluorescence staining was used to analyze the expression of c-FOS positive cells in the IO of both the Control and HA groups,and to classify different types of neurons.Mitochondrial network analysis(MiNA)was performed to quantitatively analyze the area,mean aspect ratio,branch length,and other of mitochondria in different types of neurons in the IO under ET con-ditions.Results:Compared to the Control group,the HA group exhibited motor abnormalities and significant tremors.Immunofluorescence results showed a significant increase in the number of c-FOS positive cells in the IO,primarily in GABAergic neurons.MiNA results revealed that the mitochondria of GABAergic neurons showed increased area,branch length diameter,demonstrating irregular morphology.Conclusion:ET induces activation of GABAergic neurons in the IO and leads to more prominent mitochondrial morphological changes.This provides a new perspective for further inves-tigation of the pathogenesis of essential tremor and its relationship with mitochondrial.

Objective:To observe and evaluate the clinical efficacy and safety of albumin-bound paclitaxel as first-line treatment for patients with advanced pancreatic cancer in China, and to explore the prognosis-related molecules in pancreatic cancer based on next-generation sequencing (NGS) of tumor tissues.Methods:From December 2018 to December 2020, patients with locally advanced or metastatic pancreatic cancer were recruited to accept albumin-bound paclitaxel as first-line treatment in the oncology departments of 24 hospitals in East China. The primary endpoints were overall survival (OS) and treatment related adverse events, and the secondary endpoint was progression-free survival (PFS). Adverse effects were graded using Common Terminology Criteria for Adverse Events 5.0 (CTCAE 5.0). NGS sequencing on the primary or metastatic tissue samples of pancreatic cancer obtained through surgical resection or biopsy was performed.Results:This study recruited 229 patients, including 70 patients with locally advanced pancreatic cancer (LAPC) and 159 patients with metastatic pancreatic cancer (mPC). The disease control rate was 79.9% and the objective response rate is 36.3%.The common adverse effects during treatment were anaemia (159 cases), leucopenia (170 cases), neutropenia (169 cases), increased aminotransferases (110 cases), and thrombocytopenia (95 cases), and the incidence of grade 3-4 neutropenia is 12.2% (28/229). The median follow-up time was 21.2 months (95% CI: 18.5-23.1 months). The median PFS (mPFS) was 5.3 months (95% CI: 4.37-4.07 months) and the median OS (mOS) was 11.2 months (95% CI: 9.5-12.9 months). The mPFS of patients with LAPC was 7.4 months (95% CI: 6.6-11.2 months), and their mOS was 15.5 months (95% CI: 12.6-NA months). The mPFS of patients with mPC was 3.9 months (95% CI: 3.4-5.1 months), and their mOS was 9.3 months (95% CI: 8.0-10.8 months). Multivariate Cox regression analysis showed that clinical stage ( HR=1.47, 95% CI: 1.06-2.04), primary tumor site ( HR=0.64, 95% CI: 0.48-0.86), Eastern Cooperative Oncology Group Performance Status (ECOG PS) score ( HR=2.66, 95% CI: 1.53-4.65), and whether to combine radiotherapy ( HR=0.65, 95% CI: 0.42-1.00) were independent influencing factors for the PFS of these patients. The primary tumor site ( HR=0.68, 95% CI: 0.48-0.95), ECOG score ( HR=5.82, 95% CI: 3.14-10.82), and whether to combine radiotherapy ( HR=0.58, 95% CI: 0.35-0.96) were independent influencing factors of the OS of these patients. The most frequent gene mutations in these advanced stage pancreatic patients were KRAS (89.66%), TP53 (77.01%), CDKN2A (32.18%), and SMAD4 (21.84%) by NGS of tumor tissues from 87 pancreatic cancer patients with sufficient specimens. Further analysis revealed that mutations in CDKN2B, PTEN, FGF6, and RBBP8 genes were significantly associated with an increased risk of death ( P＜0.05). Conclusion:Albumin-bound paclitaxel as first-line treatment demonstrated feasible anti-tumor efficacy and manageable safety for patients with advanced pancreatic cancer in China.

Objective To observe and analyze the effect of HbA1c level on macular microcirculation in patients with type 2 diabetes mellitus (T2DM).Methods A cross-sectional study.One hundred and twenty-four T2DM patients (124 eyes) without diabetic retinopathy who diagnosed by the examination of fundus color photography in Lixiang Eye Hospital Of Soochow University during September to December 2017 were enrolled in this study.There were 59 males (59 eyes) and 65 females (65 eyes),with the mean age of 65.06±7.99 years old.All patients underwent BCVA,fundus color photography,and OCT angiography (OCTA).The history of diabetes,hypertension and dyslipidemia were recorded in detail.According to the HbA 1 c level,patients were divided into three groups,HbA1c ideal control group (group A,HbA1c ＜7％,67 eyes),HbA1c control group (group B,7％≤HbA1c≤9％,44 eyes),and HbA1c poor control group (group C,HbA1c＞9％,13 eyes),respectively.The 3 mm × 3 mm range of the macular area was scanned by OCTA instrument.The vascular density (VD) and skeleton density (SD) of nonsegmented retinal layer (NRL),superficial retinal layer (SRL) and deep retinal layer (DRL) in the macular area and foveal avascular zone (FAZ) area,non-circularity index,axial rate (AR) of SRL were measured.The correlation between HbA1c,BCVA and VD,SD ofNRL,SRL,DRL was analyzed statistically with Spearman correlation test.The correlation between systemic factors and the above indicators was analyzed statistically with linear regression analysis.Results The results of linear regression analysis showed that HbA1 c was significantly correlated with VD (t=-3.237,-3.156,-2.050) and SD (t=-0.3.45,-3.034,-2.248) of NRL,SRL and DRL (P＜0.05);but no correlation with FAZ,non-circularity index and AR (t=1.739,0.429,1.155;P＞0.05).The differences of VD (F=6.349,5.981,3.709),SD (F=7.275,6.085,1.904) and AR (F=0.027) of NRL,SRL and DRL in group A,B and C were statistically significant (P＜0.05);but the differences of FAZ (F=1.904),non-circularity index (F=0.280) was not statistically significant (P＞0.05).Significant differences (P＜0.05) of VD and SD of NRL were found between group A and B (t=1.987,2.201),group A and C (t=3.365,3.572),group B and C (t=2.010,2.076).Significant differences (P＜0.05) of VD and SD of SRL were found between group A and B (t=2.087,2.168),group A and C (t=3.197,3.194).There were significant differences (P＜ 0.05) in SD of DRL between group A and B (t=2.239),group A and C (t=-2.519).There was significant difference in VD of DRL between group A and C (t=2.363).The results of Spearman correlation analysis showed that HbA1c was negatively correlated with VD (r=-0.273,-0.255,-0.222;P=0.002,0.004,0.013) and SD (r=-0.275,-0.236,-0.254;P＜0.05) ofNRL,SRL,DRL;positively correlated with FAZ and BCVA (r=0.221,0.183;P＜0.05).BCVA was negatively correlated with VD (r=-0.210,-0.190,-0.245) and SD (r=-0.239,-0.207,-0.296) of NRL,SRL,and DRL (P＜0.05),but not correlated with FAZ (r=0.099,P＞0.05).Conclusion The decrease of macular perfusion and the morphological change of FAZ accompanied by HbA1c increased.

Objective To analyze the pathogenesis and prevention and treatment of limb deep venous thrombosis complicated by postoperative gynaecological malignant tumours.Methods A retrospective analysis of 22 cases with limb deep venous thrombosis complicated by postoperative gynaecological malignant tumours in our hospital were analyzed.According to the situation of patients,surgery or conservative treatment was conducted.The clinical efficacy after treatment was observed.Results In 22 cases,6 cases underwent surgical treatment,16 cases underwent conservative treatment.After treatment,18 cases were cured,3 cases were effective,1 case ineffective.After treatment,the TT,Pt,APTT and FBG levels were (24.17 ±2.13)s,(18.25 ±2.13)s,(31.68 ± 10.30)s and (2.26 ±0.52) g/L,which were all better than before treatment,the differences were statistically significant (t =10.362,9.774,12.281,8.462,P =0.028,0.032,0.012,0.029).Followed up for 3 months,no recurrence of LDVT was observed.Conclusion The cases of gynecological malignant tumor have higher risk of limb deep vein thrombosis,we should taken prevention actively,once diagnosed should take effective intervention measures to improve the prognosis.

Clopidogrel was believed to be superior to aspirin by the well-known CAPRIE trial. However, no other large clinical trials demonstrated the same results, but all focused on the combination use of clopidogrel with aspirin, and combination therapy in CREDO was called the "Emperor's New Clothes". However, no one overturned the results of these clinical trials by quantitatively analyzing them. We reviewed ten large-scale clinical trials about clopidogrel. On the basis of results of CAPRIE, CREDO and CHARISMA trials, we re-estimated their minimal sample sizes and their powers by three well-established statistical methodologies. From the results of CAPRIE, we inferred that the minimal sample size should be 85 086 or 84 968 but its power was only 30.70%. A huge gap existed. The same was also true of CREDO and CHARISMA trials. Moreover, in CAPRIE trial, 0 was included in the 95% confidence interval and 1 was included in the 95% confidence interval for the relative risk. There were some paradoxical data in CAPRIE trial. We are led to conclude that the results in CAPRIE, CREDO, and from the subgroup analysis in CHARISMA trials were questionable. These results failed to demonstrate that clopidogrel was superior to aspirin or that clopidogrel used in combination with aspirin was better than aspirin alone. The cost-effectiveness analyses by some previous studies were not reliable.
