Objective To compare the effects of intra-sinus thrombolysis by using urokinase and heparin anticoagulation alone for cerebral venous sinus thrombosis (CVST).Methods Consecutive inpatients with CVST were enrolled retrospectively.Their demographic and clinical data were collected.The treatment mainly consists of intra-sinus thrombolysis by using urokinase and heparin anticoagulation alone.The outcomes were evaluated according to the modified Rankin scale (mRS) at 6 months.The mRS score ＜ 2 was defined as good outcome,and ≥2 was defined as poor outcome.Results A total of 36 patients were enrolled,including intra-sinus thrombolysis by using urokinase (n =18) and heparin anticoagulation alone (n =18).Twenty-one had good outcomes and 15 had poor outcomes.After treatment,the recanalization rate (94.4％ vs.66.7％ ;x2 =3.850,P=0.041) of the urokinase thrombolysis group and the good outcome rate at 6 months (72.2％ vs.44.4％ ; x2 =3.827,P =0.046) were significantly higher than those of the heparin anticoagulation group.The proportion of the patients receiving intra-sinus thrombolysis by using urokinase of the good outcome group was significantly higher than that of the heparin anticoagulation group (60.0％ vs.18.2 ％ ; x2 =5.360,P =0.021).Multivariate logistic regression analysis showed that the intrasinus thrombolysis by using urokinase was an independent protective factor for good outcomes in patients with CVST (odds ratio,1.085,95％ confidence interval 1.024-1.361; P=0.023),and the high coagulation state was its independent risk factor (odds ratio,0.185,95％ confidence interval 0.049-0.611;P=0.004).None of the patients occurred symptomatic cerebral hemorrhage.Conclusions Intra-sinus thrombolysis with urokinase may improve the outcomes for patients with CVST,and it is superior to the heparin anticoagulation alone.

Objective To investigate the clinical efficacy of capecitabine metronomic chemotherapy in the maintenance of elderly patients with metastatic breast cancer. Methods Fifty-six patients with metastatic breast cancer treated in Jiangsu Shengze Hospital from April 2014 to April 2017 were randomly divided into two groups according to random number table method: metronomic chemotherapy group (n = 28) and conventional chemotherapy group (n = 28). The patients in the metronomic chemotherapy group were treated with capecitabine 500 mg, 2 times/d and continuous oral administration. The conventional chemotherapy group received capecitabine 1 250 mg, 2 times/d for 14 days, rested for 7 days, 21 days was a course of treatment.After two courses,the clinical efficacy,toxicity and quality of life were evaluated. Results There were no significant differences in RR and DCR between the metronomic chemotherapy group and conventional chemotherapy group (RR: 39.3 % vs. 42.8 %, DCR: 89.3 % vs. 85.7 %, both P > 0.05). The median progression-free survival (PFS) time in the metronomic chemotherapy group was 5.8 months (95 % CI 3.23-7.44, P= 0.764) and median overall survival (OS) time was 7.9 months (95 % CI 4.15-7.95, P=0.519). The median PFS time in the conventional chemotherapy group was 7.2 months (95 % CI 3.32-6.33, P=0.835), median OS time was 10.3 months (95 % CI 4.08-7.37, P=0.463). There was no significant difference between the two groups (both P> 0.05). The incidences of hand-foot syndrome, myelosuppression and digestive tract reaction in conventional chemotherapy group were higher than those in metronomic chemotherapy group, there were significant differences between the two groups (all P < 0.05). No Ⅲ-Ⅳ level adverse reactions were found in the metronomic chemotherapy group. The overall rate of improvement of the quality of life in the metronomic chemotherapy group was significantly higher than that in the conventional chemotherapy group (92.9 % vs. 78.8 %, χ 2= 7.629, P < 0.05). Conclusion The clinical efficacy of capecitabine metronomic chemotherapy in the maintenance of elderly patients with metastatic breast cancer is similar to conventional dose maintenance therapy,but it can not only reduce the side effects, but also improve the quality of life of patients.

Gallbladder abdominal wall fistula is usually due to the acute cholecystitis with-out timely treatment, which leads the formation of abscess around the gallbladder, the gallbladder adhering to the abdominal wall and the abscess infiltrating into the skin to form a spontaneous abdominal wall fistula. Patient with gallbladder abdominal wall fistula may have the symptoms of cholecystolithiasis and acute cholecystitis. Ultrasound examination can detect the situation of gallbladder conveniently, including the internal echo after formation of abscess, the connection between the gallbladder and abdominal cavity, and the blood flow signal, to clarify the diagnosis for the subsequent treatment. The authors share the diagnosis and treatment experiences of an elderly patient with gallbladder abdominal wall fistula.

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.

This article reported a male patient with neonatal onset mental retardation autosomal dominant 35 (MRD35). The boy presented with repeated convulsions, hypotonia, enlarged head circumference, congenital muscular torticollis and feeding difficulties in the neonatal period. Dynamic electroencephalogram showed paroxysmal epileptic discharges in the left central-temporal region. High-throughput whole-exome sequencing revealed a heterozygous mutation of c.139G>A (p.Glu47Lys) in the PPP2R5D gene, which was a de novo mutation not inherited from his parents. The child had significant developmental delay at the age of one year. MRD35 lacks typical clinical manifestations and requires whole-exome sequencing for definitive diagnosis. Currently, there is no specific treatment for MRD35 and symptomatic treatments, including rehabilitation training, language training and seizure control, are mostly adopted.

Objective:To analyze the epidemic characteristics and clinical key indicators of the patients infected with SARS-CoV-2 of the local Omicron variant epidemic, to understand the clinical characteristics of mild and severe patients, and to provide a scientific basis for the effective treatment and prevention of severe disease.Methods:From January 2020 to March 2022, the clinical and laboratory data of COVID-19 patients admitted to the Fifth People's Hospital of Wuxi were retrospective analyzed, including virus gene subtypes, demographic information, clinical classification, main clinical symptoms, and key indicators of clinical testing, and the changes of clinical characteristics of the patients infected with SARS-CoV-2.Results:A total of 150 patients with SARS-CoV-2 infection were admitted, 78, 52 and 20 in 2020, 2021 and 2022, including 10, 1 and 1 severe patient, and the main infected virus strains were L, Delta, and Omicron variants. The relapse rate of patients infected with the Omicron variant was as high as 15.0% (3/20), the incidence of diarrhea decreased to 10.0% (2/20), the incidence of severe disease decreased to 5.0% (1/20), and the number of hospitalization days of mild patients increased compared with 2020 (days: 20.43±1.78 vs. 15.84±1.12); respiratory symptoms were reduced, and the proportion of pulmonary lesions decreased to 10.5%; the virus titer of severely ill patients with SARS-CoV-2 Omicron variant infection (day 3) was higher than that of L-type strain (Ct value: 23.92±1.16 vs. 28.19±1.54). The acute plasma cytokines interleukin (IL-6, IL-10) and tumor necrosis factor-α (TNF-α) were significantly lower in patients with severe Omicron variant new coronavirus infection than those with mild disease [IL-6 (ng/L): 3.92±0.24 vs. 6.02±0.41, IL-10 (ng/L): 0.58±0.01 vs. 4.43±0.32, TNF-α (ng/L): 1.73±0.02 vs. 6.91±1.25, all P < 0.05], while γ-interferon (IFN-γ) and IL-17A were significantly higher than patients with mild disease [IFN-γ (ng/L): 23.07±0.17 vs. 13.52±2.34, IL-17A (ng/L): 35.58±0.08 vs. 26.39±1.37, both P < 0.05]. Compared with previous epidemics (2020 and 2021), the proportion of CD4/CD8 ratio, lymphocyte count, eosinophil and serum creatinine decreased in patients with mild Omicron infection in 2022 (36.8% vs. 22.1%, 9.8%; 36.8% vs. 23.5%, 7.8%; 42.1% vs. 41.2%, 15.7%; 42.1% vs. 19.1%, 9.8%), the proportion of patients with elevated monocyte count and procalcitonin was large (42.1% vs. 50.0%, 23.5%; 21.1% vs. 5.9%, 0). Conclusion:The incidences of severe disease in patients with SARS-CoV-2 Omicron variant infection was significantly lower than that of previous epidemics, and the occurrence of severe diseases was still related to the underlying diseases.

Objective:To explore the clinicopathologic features and renal prognosis of patients with post-transplant membranous nephropathy (MN).Methods:Patients with allograft biopsy-proven MN were reviewed retrospectively and divided into unknown etiology group (A, n=12) and recurrent membranous nephropathy (rMN) group (B, n=7). Their clinicopathological data and renal prognosis were assessed and compared.Results:No differences existed in the proportion of living-related donor or post-transplant allograft function. Group B had recurrence at 16.4 months after transplantation and it was significantly shorter than group A. Allograft impairment manifested as proteinuria, nephrotic syndrome and/or renal insufficiency in both groups. The positive rate of serum anti-PLA2R antibody and renal PLA2R staining was significantly higher in group B than that in group A. Similarly, the intensity of IgG4 subtype staining was also stronger in group B than that in group A. The 5-year cumulative renal survival rates from end-stage renal disease (ESRD) were 77.8% and 66.7% in groups A and B respectively. No significant inter-group difference existed in renal prognosis.Conclusions:Anti-PLA2R antibody plays an important role in the recurrence of rMN after renal allografting. PLA2R staining is useful for detecting primary disease and its sensitivity is higher than that of serum anti-PLA2R antibody. Rituximab is an effective treatment for post-transplant MN. Follow-up studies with a larger sample size are required for further verification.

Objective To characterize the clinicopathologic features,treatment efficacy and prognoses of proliferative glomerulonephritis with monoclonal IgG deposits (PGNMID) in renal allografts.Methods Electronic medical records of Jinling Hospital were searched for PGNMID that was diagnosed during January 2008 to April 2017.Clinicopathologic features,treatment regimens and prognoses information were retrieved and analyzed.Results We identified 5 cases of PGNMID with clinical symptoms of proteinuria (5/5),serum creatinine elevation (4/5) or hematuria (4/5) 5 to 19 months after kidney transplantation.Various light microscopic features were observed,with predominantly membranoprolifeative pattern.Mild mesangial proliferation pattern could be observed in early stages of disease progression.Immunofluorescence revealed monoclonal IgG3κ in 3 patients and IgG3λ in another 2 cases.One case of PGNMID with normal light microscopy but monoclonal IgG deposits was verified by IgG and light-chain subtyping.In the 4 patients treated with rituximab or bortezomib,decreased proteinuria was achieved in all treated patients while the decreases in serum creatinine decrease were only observed in 2 patients At last follow-up,one patient was in dialysis and serum creatinine levels of other 2 patients were ＞265.2 μmol/L.Conclusion Membranoprolifeative pattern is the most frequently observed microscopic findings and IgG3 is the most frequent IgG subtype in PGNMID.PGNMID recurs shortly after kidney transplantation.Rituximab and/or bortezomib is conducive to decrease proteinuria while their efficacy to decrease serum creatinine is dubious.The most effective treatment protocol for PGNMID remains to be determined in larger samples.

Background: Xylazole (Xyl) is a veterinary anesthetic that is structurally and functionally similar to xylazine. However, the effects of Xyl in vitro remain unknown. Objectives: This study aimed to investigate the anesthetic mechanism of Xyl using fetal rat nerve cells treated with Xyl. Methods: Fetal rat nerve cells cultured for seven days were treated with 10, 20, 30, and 40 μg/ mL Xyl for 0, 5, 10, 15, 20, 25, 30, 45, 60, 90, and 120 min. Variations of amino acid neurotransmitters (AANTs), Nitric oxide-Cyclic GMP (NO-cGMP) signaling pathway, and ATPase were evaluated. Results: Xyl decreased the levels of cGMP and NO in nerve cells. Furthermore, Xyl affected the AANT content and Na+ -K+ -ATPase and Ca2+ -Mg2+ -ATPase activity in nerve cells. These findings suggested that Xyl inhibited the NO-cGMP signaling pathway in nerve cells in vitro. Conclusions This study provided new evidence that the anesthetic and analgesic effects of Xyl are related to the inhibition of the NO-cGMP signaling pathway.

AIM:To investigate the role of Ywhab in the growth of mouse B-cell lymphoma,and to explore the potential underlying mechanisms.METHODS:The correlation between Ywhab and human diffuse large B-cell lymphoma(DLBCL)was investigated by bioinformatics analysis.Infection with retroviral vector was performed to establish stable mouse B-cell lymphoma 38B9 cell line with overexpression of Ywhab gene,which was verified by RT-qPCR and Western blot.The impact of Ywhab overexpression on 38B9 cell growth both in vitro and in vivo was detected by cell counting,CCK-8 assay,and subcutaneous tumor loading experiments.The expression of apoptosis-related proteins was detected by RT-qPCR and Western blot.Co-immunoprecipitation combined with mass spectrometry(CoIP-MS)was employed to search for proteins specifically binding to Ywhab gene product 14-3-3β,which was confirmed by Western blot and molecu-lar docking analysis.RESULTS:The Ywhab gene exhibited low expression in DLBCL,which was correlated with poor clinical prognosis of DLBCL patients.Compared with normal mouse bone marrow B cells,Ywhab expression was low in 38B9 cells.Overexpression of Ywhab induced apoptosis of 38B9 cells both in vitro and in vivo,promoted the expression of pro-apoptotic proteins Puma,Noxa and Bax at both mRNA and protein levels,and inhibited the mRNA and protein expres-sion of anti-apoptotic protein Bcl2(P＜0.05).The 14-3-3β protein specifically bound to Hsp90aa1 and reduced Hsp90aa1 protein levels,thereby suppressing the growth of 38B9 cells.CONCLUSION:Ywhab promotes the apoptosis of B-cell lymphoma cells by binding to Hsp90aa1 and thereby inhibiting the function of Hsp90aa1.
