Efficacy and safety of allogeneic umbilical cord-derived mesenchymal stem cells for the treatment of complex perianal fistula in Crohn's disease: a pilot study.

OBJECTIVES: The aim of the study was to evaluate the efficacy and safety of allogeneic umbilical cord-derived mesenchymal stem cells (TH-SC01) for complex perianal fistula in patients with Crohn's disease (CD). METHODS: This was an open-label, single-arm clinical trial conducted at Jinling Hospital. Adult patients with complex treatment-refractory CD perianal fistulas (pfCD) were enrolled and received a single intralesional injection of 120 million TH-SC01 cells. Combined remission was defined as an absence of suppuration through an external orifice, complete re-epithelization, and absence of collections larger than 2 cm measured by magnetic resonance imaging (MRI) at 24 weeks after cell administration. RESULTS: A total of 10 patients were enrolled. Six patients (60.0%) achieved combined remission at 24 weeks. The number of draining fistulas decreased in 9 (90.0%) and 7 (70.0%) patients at weeks 12 and 24, respectively. Significant improvement in Perianal Crohn Disease Activity Index, Pelvic MRI-Based Score, Crohn Disease Activity Index, and quality of life score were observed at 24 weeks. No serious adverse events occurred. The probability of remaining recurrence-free was 70% at week 52. CONCLUSION: The study demonstrated that local injection of TH-SC01 cells might be an effective and safe treatment for complex treatment-refractory pfCD after conventional and/or biological treatments fail (ClinicalTrials.gov ID, NCT04939337). TRIAL REGISTRATION: The study was retrospectively registered on www. CLINICALTRIALS: gov (NCT04939337) on June 25, 2021.

Trend of drug clinical trials in mainland China from 2009 to 2020.

With the development of linnovative regulations on drug clinical trials in mainland China, the quantity and quality of drug clinical trials have gradually improved over the past decade. Based on the information of the clinical trials from the online drug clinical trial registration platform of National Medical Products Administration, we reviewed the data of drug clinical trials in mainland China from 2009 to 2020. A total of 8,593 clinical trials have been conducted during this period. The annual number of clinical trials has been increasing gradually, and peaked in 2017. There were 2,127, 1,051, 1,551, and 156 phases I, II, III, and IV clinical trials respectively. In addition, there were 3,441 bioequivalence studies. Trials for anti-tumor drugs ranked the highest (19.45%), followed by trials of drugs for infections and infestations (12.96%) and those for cardiovascular diseases (9.00%). Meanwhile the number of the clinical trial sites also increased annually. However, there were only 116 and 130 clinical trials of drugs for children and rare diseases respectively. The geographical distribution of the sites was uneven. This mapping review provides an overall look of clinical trials in China, which may be useful for domestic and international sponsors.

Diagnosis and Management of Pediatric Papillary Craniopharyngiomas.

OBJECTIVE: Papillary craniopharyngioma (PCP) was previously believed to occur only in adults. Sporadic pediatric PCP (PPCP) confirmed by detection of BRAF V600E mutation has been reported since 2018, but is often misdiagnosed before being diagnosed definitively. We aimed to evaluate PPCP characteristics and propose diagnostic criteria for prompt diagnosis, seeking to reduce patient morbidity and mortality and reduce costs linked to misdiagnosis. METHODS: This study included 5 patients with PPCPs whose data were retrieved retrospectively from among 1032 patients with craniopharyngiomas admitted to Sanbo Brain Hospital Management Group from March 2017 to May 2021. Patients' demographics, clinical presentation, tumor imaging characteristics, histopathologic results, surgical approaches, and postoperative outcomes were analyzed. RESULTS: PPCP was misdiagnosed intraoperatively as sellar abscess (n = 4) or Rathke cleft cyst (n = 1). Preoperative magnetic resonance imaging showed that all tumors were under the saddle diaphragm, and the cyst wall was enhanced (n = 5). Computed tomography scans showed scattered high-density signs (n = 4). No recurrence was noted after complete resection. Postoperative hypothalamic dysfunction was mild. BRAF V600E mutation was confirmed in all cases by sequencing and immunohistochemistry. Immunohistochemistry showed granulation and inflammation and MPO, CD3, CD20, CD38, CD68, and CD163 were positively expressed. CONCLUSIONS: Misdiagnosis of PPCP is responsible for failed surgical treatment. We propose that prompt diagnosis of PPCP can be achieved if preoperative magnetic resonance images show the tumor under saddle diaphragm with tumor wall enhancement and computed tomography scans show high-density signs scattered in the tumor, which leads to safe, effective tumor resection. Our proposed diagnosis and treatment strategy for PPCP reduces morbidity and mortality.

A Novel Necroptosis-Associated IncRNAs Signature for Prognosis of Head and Neck Squamous Cell Carcinoma.

Purpose: The prognosis of head and neck squamous cell carcinoma (HNSCC) is poor. Necroptosis is a novel programmed form of necrotic cell death. The prognostic value of necroptosis-associated lncRNAs expression in HNSCC has not been explored. Methods: We downloaded mRNA expression data of HNSCC patients from TCGA databases. Prognostic lncRNAs were identified by univariate Cox regression. LASSO was used to establish a model with necroptosis-related lncRNAs. Kaplan-Meier analysis and ROC were applied to verify the model. Finally, functional studies including gene set enrichment analyses, immune microenvironment analysis, and anti-tumor compound IC50 prediction were performed. Results: We identified 1,117 necroptosis-related lncRNAs. The Cox regression showed 55 lncRNAs were associated with patient survival (p < 0.05). The risk model of 24- lncRNAs signature categorized patients into high and low risk groups. The patients in the low-risk group survived longer than the high-risk group (p < 0.001). Validation assays including ROC curve, nomogram and correction curves confirmed the prediction capability of the 24-lncRNA risk mode. Functional studies showed the two patient groups had distinct immunity conditions and IC50. Conclusion: The 24-lncRNA model has potential to guide treatment of HNSCC. Future clinical studies are needed to verify the model.

A Modified Approach with Caval Transection for Supracardiac Total Anomalous Pulmonary Venous Connection: Comparison Between Conventional and Sutureless Surgery in 173 Patients.

The efficacy of primary sutureless repair for supracardiac total anomalous pulmonary venous connection (TAPVC) needs to be confirmed. This study aimed to compare the long-term outcomes between the conventional surgery and the sutureless technique with a modified approach in superior TAPVC. Between January 2008 and December 2018, 173 patients with supracardiac TAPVC underwent surgery either with the conventional procedure (n = 130) or the sutureless repair (n = 43). Multivariate analysis and competing-risk analysis were used to identify risk factors for early death and postoperative pulmonary venous obstruction (PVO), respectively. Among 173 patients who underwent repair of supracardiac TAPVC, 46 (28%) had preoperative PVO, and 22 (12.7%) had postoperative PVO. The sutureless group had a lower postoperative PVO rate compared with the conventional group (p = 0.027). The risk factors for death were age ≤ 28 days [odds ratio (OR), 11.56; 95% confidence interval (CI) 1.33-100.47, p = 0.015], weight ≤ 3 kg (OR 9.57; 95% CI 1.58-58.09, p = 0.009), emergency operation (OR 19.24; 95% CI 3.18-116.35, p = 0.002), cardiopulmonary bypass time (OR 2.16; 95% CI 1.36-3.43, p = 0.003), cross-clamp time (OR 1.73; 95% CI 1.20-2.50, p = 0.022), and duration of ventilation (OR 1.11; 95% CI 1.02-1.21, p = 0.027). Age ≤ 28 days [Hazard Ratio (HR) 1.92; 95% CI 1.92-11.02, p < 0.001] and preoperative PVO (HR 41.70; 95% CI 8.15-213.5, p < 0.001) were associated with postoperative PVO. The sutureless repair is a reliable technique for supracardiac TAPVC. Age ≤ 28 days is associated with 30-day mortality and postoperative PVO.

Prognostic nomogram based on immune scores for laryngeal squamous cell cancer.

PURPOSE: Immune scores have been used as a prognostic factor for various types of cancer. However, the association between immune scores and the prognosis of laryngeal squamous cell cancer (LSCC) has not yet been investigated. This study aimed to explore the prognostic significance of immune scores and construct a clinical nomogram to predict the survival of patients with LSCC. METHODS: The clinicopathological characteristics and immune scores of 102 patients with LSCC were obtained from TCGA database and a nomogram was developed. C-index and calibration curves were applied to assess the performance of the model. RESULTS: Patients with higher immune scores had significantly better overall survival (OS). The prognostic nomogram presented a good performance in survival prediction. CONCLUSIONS: High immune scores are correlated with improved OS in patients with LSCC. In addition, the nomogram developed for this study may assist clinicians in the prognostic evaluation of patients with LSCC.

Systematic evaluation of therapeutic effects of stem cell transplantation trials for heart diseases in China.

BACKGROUND: To systematically assess the quality of reports of clinical trials of stem cell for heart diseases published in Chinese. METHODS: The quality of reports was assessed according to the CONSORT statement and the Jadad score. The association between the CONSORT scores and the reported therapeutic effects was evaluated. RESULTS: A total of 36 randomized clinical trials were identified, and 1552 patients were included. The mean CONSORT score was 7.06 (SD = 2.99). The proportion of reports with a Jadad score of 3 was 8.33%. The improvement of left ventricular function, myocardial perfusion area, left ventricular diastolic diameter, and cardiac output decreased with the increase in the CONSORT score. CONCLUSIONS: The percentages of high-quality reports published in Chinese on stem cell therapy for heart diseases are low. Although stem cell transplantation seems promising for heart diseases, high-quality studies are needed to verify the conclusions．.

Unrelated cord blood transplantation versus haploidentical transplantation in adult and pediatric patients with hematological malignancies-A meta-analysis and systematic review.

Several clinical trials have compared the safety and efficacy of umbilical cord blood transplantation (UCBT) with haploidentical transplantation (HIT) in patients with hematological malignancies. To obtain more reliable evidence, we performed a systematic review and meta-analysis. Seven studies were included and there was a combined total of 102 children and 1311 adults undergoing UCBT, along with 94 children and 915 adults undergoing HIT. Pooled comparisons of studies of UCBT and HIT in children found that the incidence of chronic graft-versus-host disease (GVHD) and disease-free survival (DFS) at 2 years (RR 0.34, 95% CI (0.03, 4.53), P=0.41; HR 0.51, 95% CI (0.23, 1.09), P=0.08) were not statistically different. For adults, although the incidence of grade II-IV acute GVHD differ (RR 1.17, 95% CI (1.02, 1.34), P=0.02), but it indicates a very small difference between the groups as the RR is barely above 1. On the other hand, although the incidence of grade III-IV acute GVHD did not differ (RR 1.51, 95% CI (0.78, 2.92), P=0.22), but there is a tendency of higher risk for the UCBT. And the incidence of chronic GVHD did not differ (RR 1.05, 95% CI (0.82, 1.34), P=0.71). There was no difference in relapse, non-relapse mortality (NRM) and DFS at 2 years (HR 0.92, 95% CI (0.74, 1.13), P=0.42; HR 0.87, 95% CI (0.49, 1.52) P=0.62 and HR 0.74 95% CI (0.39, 1.43), P=0.37). In conclusion, UCBT and HIT could be considered as equally effective option for adult patients without HLA-matched donors.

Identification of core biomarkers associated with pathogenesis and prognostic outcomes of laryngeal squamous-cell cancer using bioinformatics analysis.

PURPOSE: Despite advances in the treatment of laryngeal squamous-cell carcinoma (LSCC), the survival rate of LSCC remains poor. Thereby, it is urgent to identify novel diagnostic and prognostic biomarkers for LSCC. The study aimed to identify potential core genes associated with the pathogenesis and prognosis of LSCC. METHODS: Differentially expressed genes between LSCC and normal laryngeal tissue samples were screened by an integrated analysis of data from GEO and TCGA databases. Core genes related to the pathogenesis and prognosis of LSCC were identified by employing protein-protein interaction network and Cox proportional hazards model analyses. RESULTS: Ten hub genes (AURKA, AURKB, CDC45, KIF2C, NDC80, EXO1, TYMS, RAD51AP1, ITGA3, and UBE2T) that might be highly related to the pathogenesis of LSCC were identified. An eight-gene prognostic signature consisted of ZG16B, STATH, RTN4R, MSRA, CBX8, SLC5A1, EFNB1 and CNTFR was constructed with a good performance in predicting overall survivals. CONCLUSION: Our findings might shed some new light on the pathogenesis of LSCC and help identify new therapeutic targets of LSCC.

Efficiency of Modified Triple-Branched Stent Graft in Type I Aortic Dissection: Two-Year Follow-up.

BACKGROUND: The efficacy of hemiarch replacement combined with a modified triple-branched stent graft in Debakey type I aortic dissection remains to be confirmed. METHODS: From January 2016 to December 2017, 167 patients with acute Debakey type I aortic dissection underwent hemiarch replacement combined with a modified triple-branched stent graft. The clinical and imaging data were retrospectively analyzed. The early composite endpoint was defined to comprise perioperative mortality, permanent neurologic deficits, and renal failure requiring hemodialysis at discharge. RESULTS: The overall 30-day mortality was 4.2% (7 of 167). The incidence of the composite endpoint was 11.4% (19 of 167). The risk factors for the composite endpoint were malperfusion syndrome (odds ratio 5.17; 95% confidence interval, 1.46 to 18.35; P = .011) and creatine greater than 1.5 mg/dL (odds ratio 5.44; 95% confidence interval, 2.27 to 13.06; P < .001). The overall survival was 94% at 1 year and 92.2% at 2 years during a median follow-up of 20.9 ± 9.6 months. Three patients required distal aorta reintervention. Complete thrombosis in the false lumen of the descending aorta at the level of the pulmonary bifurcation and at the level of the celiac trunk was observed in 98.8% and 10.8% of the patients, respectively. CONCLUSIONS: Hemiarch replacement combined with a modified triple-branched stent graft is a reliable technique for acute Debakey type I aortic dissection as indicated by 2 years of follow-up.

Increased perihematomal neuron autophagy and plasma thrombin-antithrombin levels in patients with intracerebral hemorrhage: An observational study.

Animal studies have demonstrated that autophagy was involved in neuronal damage after intracerebral hemorrhage (ICH). Several studies showed thrombin-antithrombin (TAT) plasma levels were elevated in patients with ICH. In this study, we aimed to evaluate if autophagy occurred in patients with ICH; and the relationship between the severity of brain injury and plasma TAT levels.A novel tissue harvesting device was used during hematoma removal surgery to collect loose fragments of tissue surrounding the affected brain area in 27 ICH patients with hematoma volumes of >30 mL in the basal ganglia. Control tissues were obtained from patients who underwent surgery for arteriovenous malformation (n = 25). Transmission electron microscopy (TEM) and immunohistochemistry for autophagy-related proteins were used to evaluate the ultrastructural and morphologic cellular characteristics; and the extent of autophagy in the recovered tissue specimens. Stroke severity was assessed by using the Glasgow Coma Scale (GCS) and the National Institutes of Health Stroke Scale (NIHSS). An enzyme-linked immunosorbent assay (ELISA) was used to measure plasma TAT levels.Transmission electron microscopy showed autophagosomes and autolysosomes exist in neurons surrounding the hematoma, but not in the control tissues. The number of cells containing autophagic vacuoles correlated with the severity of brain injury. Immunohistochemistry showed strong LC3, beclin 1, and cathepsin D staining in ICH tissue specimens. Plasma TAT levels correlated positively with autophagic cells and ICH severity (P < .01).Autophagy was induced in perihematomal neurons after ICH. Autophagy and plasma TAT levels correlated positively with severity of brain injury. These results suggest that autophagy and increased plasma TAT levels may contribute to the secondary damage in ICH patients.

Comparison of the short-term and long-term outcomes of surgical treatment versus endoscopic treatment for early esophageal squamous cell neoplasia larger than 2 cm: a retrospective study.

BACKGROUND: NCCN Guidelines of esophageal cancer recommend that endoscopic therapy is considered "preferred" for patients with limited early-stage disease less than or equal to 2 cm. However, there is currently no definite evidence to support either endoscopic therapy or esophagectomy for early esophageal cancer larger than 2 cm. We aimed to explore the optimal treatment for this condition. METHODS: From January 2010 to June 2016, 116 patients with early esophageal neoplasia [high-grade dysplasia (HGD), lamina propria and muscularis mucosae (T1a) cancer, selected superficial submucosa (T1b) cancer without lymph node metastases] larger than 2 cm and treated either surgically or endoscopically were included. RESULTS: Endoscopic therapy was performed in 69 patients and esophagectomy in 47 patients, respectively. The median follow-up time was 43.8 months in the endoscopic cohort and 49.4 months in the surgical cohort. The overall survival was similar between the two cohorts (97.1% vs. 91.5%, P = 0.18). Survival without readmission for treatment-related complicates was also similar. Minor and severe procedure-related complications occurred more often in the surgical cohort than in the endoscopic cohort (63.8% vs. 43.5% and 8.5% vs. 0 respectively, P < 0.05 for both). Four patients in the endoscopic cohort had to undergo additional esophagectomy and were alive during follow-up. There were no procedure-related deaths in the endoscopic cohort, whereas two deaths occurred in the surgical cohort. Recurrence occurred in nine patients in the endoscopic group (13%): six with local recurrence, one with residual neoplasia and two with metachronous neoplasia. None of them died after repeated endoscopic treatments. CONCLUSIONS: Efficacy was similar between endoscopic therapy and esophagectomy in the treatment of early esophageal squamous cell neoplasia larger than 2 cm and endoscopic therapy was associated with fewer and manageable complications. We recommend endoscopic treatment should be preferred selected for early esophageal neoplasia larger than 2 cm.

Efficacy of intracellular immune checkpoint-silenced DC vaccine.

BACKGROUND: DC-based tumor vaccines have had limited clinical success thus far. SOCS1, a key inhibitor of inflammatory cytokine signaling, is an immune checkpoint regulator that limits DC immunopotency. METHODS: We generated a genetically modified DC (gmDC) vaccine to perform immunotherapy. The adenovirus (Ad-siSSF) delivers two tumor-associated antigens (TAAs), survivin and MUC1; secretory bacterial flagellin for DC maturation; and an RNA interference moiety to suppress SOCS1. A 2-stage phase I trial was performed for patients with relapsed acute leukemia after allogenic hematopoietic stem cell transplantation: in stage 1, we compared the safety and efficacy between gmDC treatment (23 patients) and standard donor lymphocyte infusion (25 patients); in stage 2, we tested the efficacy of the gmDC vaccine for 12 acute myeloid leukemia (AML) patients with early molecular relapse. RESULTS: gmDCs elicited potent TAA-specific CTL responses in vitro, and the immunostimulatory activity of gmDC vaccination was demonstrated in rhesus monkeys. A stage 1 study established that this combinatory gmDC vaccine is safe in acute leukemia patients and yielded improved survival rate. In stage 2, we observed a complete remission rate of 83% in 12 relapsed AML patients. Overall, no grade 3 or grade 4 graft-versus-host disease incidence was detected in any of the 35 patients enrolled. CONCLUSIONS: This study, with combinatory modifications in DCs, demonstrates the safety and efficacy of SOCS1-silenced DCs in treating relapsed acute leukemia. TRIAL REGISTRATION: ClinicalTrials.gov NCT01956630. FUNDING: National Institute of Health (R01CA90427); the Key New Drug Development and Manufacturing Program of the "Twelfth Five-Year Plan" of China (2011ZX09102-001-29); and Clinical Application Research of Beijing (Z131107002213148).

Fuzheng Qingjie granules potentiate the anticancer effect of cyclophosphamide by regulating cellular immune function and inducing apoptosis in Hepatoma 22 tumor-bearing mice.

Fuzheng Qingjie (FZQJ) is a polyherbal Chinese medicine that has previously been implemented as an adjuvant therapy for gastrointestinal cancer. The present study investigated whether FZQJ is able to potentiate the anticancer effect of cyclophosphamide (CTX). Hepatoma 22 tumor-bearing mice were randomly divided into a vehicle group, CTX group, FZQJ group and combination (CTX+FZQJ) group. In addition, untreated mice without H22 cells served as blank controls. Seven days post-treatment, the mice were sacrificed and the tumors were weighed. Blood cells were evaluated using an automatic hemocytometer analyzer and flow cytometer. The expression levels of interleukin (IL)-2 and tumor necrosis factor (TNF)-α were evaluated using a radioimmunoassay. Apoptotic cells were observed using a terminal deoxynucleotidyl transferase dUTP nick-end labeling assay. Alanine transaminase, aspartate aminotransferase, blood urea nitrogen and creatinine were examined using an automatic biochemical analyzer. The results demonstrated that the tumor inhibitory rate and apoptosis index were higher in the combination group, compared with those in the CTX group. Notably, FZQJ was able to alleviate CTX-induced decreases in the numbers of white blood cells and platelets, CD3+ and CD4+ T lymphocyte subsets, and the concentration of hemoglobin, body weight and thymus index, and increase serum TNF-α and IL-2 levels without overt hepatorenal toxicity. These results suggest that FZQJ granules may enhance the anticancer effect of CTX, in addition to alleviating the side effects.

Relation of phosphodiesterase type 5 inhibitors and malignant melanoma: a meta-analysis and systematic review.

Data on the association between using PDE5 inhibitors and malignant melanoma are conflicting. To estimate the relation of using PDE5 inhibitors with risk of malignant melanoma, Medline (Ovid) and Embase (Ovid) databases were searched up to February 2017, and a random effects model was used to calculate the summary risk estimates. Five observational studies were included. Five studies reports encompassed a total of 15,979 melanoma cases occurring among 1, 188,414 participants. The pooled multivariable-adjusted RR of melanoma in patients with using PDE5 inhibitors was 1.12 (95% CI: 1.03-1.21, I2 = 0.48). Findings from this systematic review support that PDE5 inhibitor use is associated with increased risk of melanoma in ED patients, the result remains inclusive and warrants further study in the future.

Fuzheng Qingjie Granules Inhibit Growth of Hepatoma Cells via Inducing Mitochondria-Mediated Apoptosis and Enhancing Immune Function.

Fuzheng Qingjie (FZQJ) granules, a compound Chinese medicine, have been used as an adjuvant therapy for alimentary tract cancers. However, the underlying anticancer mechanisms are still not well understood. In the present study, HepG2 cells were treated with FZQJ-containing serum. Cell proliferation was evaluated using MTT assay. Apoptosis was analyzed using a flow cytometer. Cell ultrastructure was observed under a transmission electron microscope. The mitochondrial membrane potential (Δψ) was examined with JC-1 dye. In H22 tumor-bearing mice, CD4+ T cells, CD8+ T cells, CD3+ T cells, and natural killer (NK) cells in peripheral blood were evaluated cytometrically. Interleukin (IL)-2 and tumor necrosis factor (TNF)-α levels were measured using radioimmunoassay.The mRNA levels of Bax and Bcl-2 were examined by reverse transcription-polymerase chain reaction. The protein levels of Bax, Bcl-2, cytochrome C, caspase 3 and 9, PARP, and CD69 were examined by Western blotting. The apoptotic cells in tissues were observed using TUNEL method. Alanine transaminase (ALT), aspartate transaminase (AST), blood urea nitrogen (BUN), and creatinine (CRE) were detected by an automatic biochemical analyzer. The results showed that FZQJ-containing serum remarkably inhibited proliferation of HepG2 cells in dose- and time-dependent manners, induced HepG2 cell apoptosis and caused a decrease of Δψ. Analysis of tumor tissue showed that FZQJ-induced apoptosis was accompanied by downregulation of Bcl-2 and upregulation of Bax, release of cytochrome c, activation of caspase 3 and 9, and cleavage of PARP. In addition, FZQJ increased the percentages of CD4+ T and NK cells, the ratio of CD4+/CD8+ T cells as well as the levels of serum TNF-α. FZQJ also increased CD69 expression in tumor tissue. No hepatorenal toxicity was observed in H22 tumor-bearing mice. These results indicated that FZQJ could inhibit the growth of hepatoma cells via regulating immune function and inducing mitochondria mediated apoptosis.

Synergisic effect of APRIL knockdown and Jiedu Xiaozheng Yin, a Chinese medicinal recipe, on the inhibition of hepatocellular carcinoma cell proliferation.

It is well documented that A proliferation-inducing ligand (APRIL), a member of the tumor necrosis factor superfamily, plays a crucial role in the occurrence and development of tumors. In the present study, we evaluated the synergistic effect of APRIL knockdown and Jiedu Xiaozheng Yin (JXY), a Traditional Chinese Medicinal recipe, on the inhibition of hepatocellular carcinoma (HCC) cell proliferation and elucidated the underlying mechanism. The results demonstrated that both APRIL knockdown using small interfering RNA (siRNA) and JXY treatment could trigger cell cycle arrest and cell apoptosis, and suppress HCC cell proliferation through an NF-κB-related pathway. Synergism was further demonstrated between APRIL knockdown and JXY treatment. In conclusion, these results indicate that APRIL is a target gene for HCC and combination of siRNA-APRIL and JXY application holds great promise as a novel approach for the treatment of APRIL-positive HCC.

Subcutaneous administration of liraglutide ameliorates learning and memory impairment by modulating tau hyperphosphorylation via the glycogen synthase kinase-3ß pathway in an amyloid ß protein induced alzheimer disease mouse model.

Type 2 diabetes mellitus is a risk factor for Alzheimer's disease (AD). The glucagon-like peptide-1 analog liraglutide, a novel long-lasting incretin hormone, has been used to treat type 2 diabetes mellitus. In addition, liraglutide has been shown to be neurotrophic and neuroprotective. Here, we investigated the effects of liraglutide on amyloid ß protein (Aß)-induced AD in mice and explored its mechanism of action. The results showed that subcutaneous administration of liraglutide (25nmol/day), once daily for 8 weeks, prevented memory impairments in the Y Maze and Morris Water Maze following Aß1-42 intracerebroventricular injection, and alleviated the ultra-structural changes of pyramidal neurons and chemical synapses in the hippocampal CA1 region. Furthermore, liraglutide reduced Aß1-42-induced tau phosphorylation via the protein kinase B and glycogen synthase kinase-3ß pathways. Thus liraglutide may alleviate cognitive impairment in AD by at least decreasing the phosphorylation of tau.

Umbilical Cord Mesenchymal Stromal Cell With Autologous Bone Marrow Cell Transplantation in Established Type 1 Diabetes: A Pilot Randomized Controlled Open-Label Clinical Study to Assess Safety and Impact on Insulin Secretion.

OBJECTIVE: To determine the safety and effects on insulin secretion of umbilical cord (UC) mesenchymal stromal cells (MSCs) plus autologous bone marrow mononuclear cell (aBM-MNC) stem cell transplantation (SCT) without immunotherapy in established type 1 diabetes (T1D). RESEARCH DESIGN AND METHODS: Between January 2009 and December 2010, 42 patients with T1D were randomized (n = 21/group) to either SCT (1.1 × 10(6)/kg UC-MSC, 106.8 × 10(6)/kg aBM-MNC through supraselective pancreatic artery cannulation) or standard care (control). Patients were followed for 1 year at 3-month intervals. The primary end point was C-peptide area under the curve (AUC(C-Pep)) during an oral glucose tolerance test at 1 year. Additional end points were safety and tolerability of the procedure, metabolic control, and quality of life. RESULTS: The treatment was well tolerated. At 1 year, metabolic measures improved in treated patients: AUCC-Pep increased 105.7% (6.6 ± 6.1 to 13.6 ± 8.1 pmol/mL/180 min, P = 0.00012) in 20 of 21 responders, whereas it decreased 7.7% in control subjects (8.4 ± 6.8 to 7.7 ± 4.5 pmol/mL/180 min, P = 0.013 vs. SCT); insulin area under the curve increased 49.3% (1,477.8 ± 1,012.8 to 2,205.5 ± 1,194.0 mmol/mL/180 min, P = 0.01), whereas it decreased 5.7% in control subjects (1,517.7 ± 630.2 to 1,431.7 ± 441.6 mmol/mL/180 min, P = 0.027 vs. SCT). HbA1c decreased 12.6% (8.6 ± 0.81% [70.0 ± 7.1 mmol/mol] to 7.5 ± 1.0% [58.0 ± 8.6 mmol/mol], P < 0.01) in the treated group, whereas it increased 1.2% in the control group (8.7 ± 0.9% [72.0 ± 7.5 mmol/mol] to 8.8 ± 0.9% [73 ± 7.5 mmol/mol], P < 0.01 vs. SCT). Fasting glycemia decreased 24.4% (200.0 ± 51.1 to 151.2 ± 22.1 mg/dL, P < 0.002) and 4.3% in control subjects (192.4 ± 35.3 to 184.2 ± 34.3 mg/dL, P < 0.042). Daily insulin requirements decreased 29.2% in only the treated group (0.9 ± 0.2 to 0.6 ± 0.2 IU/day/kg, P = 0.001), with no change found in control subjects (0.9 ± 0.2 to 0.9 ± 0.2 IU/day/kg, P < 0.01 vs. SCT). CONCLUSIONS: Transplantation of UC-MSC and aBM-MNC was safe and associated with moderate improvement of metabolic measures in patients with established T1D.
