ABSTRACT

The immune checkpoint blockade therapy has profoundly revolutionized the field of cancer immunotherapy. However, despite great promise for a variety of cancers, the efficacy of immune checkpoint inhibitors is still low in colorectal cancer (CRC). This is mainly due to the immunosuppressive feature of the tumor microenvironment (TME). Emerging evidence reveals that certain chemotherapeutic drugs induce immunogenic cell death (ICD), demonstrating great potential for remodeling the immunosuppressive TME. In this study, the potential of ginsenoside Rg3 (Rg3) as an ICD inducer against CRC cells was confirmed using in vitro and in vivo experimental approaches. The ICD efficacy of Rg3 could be significantly enhanced by quercetin (QTN) that elicited reactive oxygen species (ROS). To ameliorate in vivo delivery barriers associated with chemotherapeutic drugs, a folate (FA)-targeted polyethylene glycol (PEG)-modified amphiphilic cyclodextrin nanoparticle (NP) was developed for co-encapsulation of Rg3 and QTN. The resultant nanoformulation (CD-PEG-FA.Rg3.QTN) significantly prolonged blood circulation and enhanced tumor targeting in an orthotopic CRC mouse model, resulting in the conversion of immunosuppressive TME. Furthermore, the CD-PEG-FA.Rg3.QTN achieved significantly longer survival of animals in combination with Anti-PD-L1. The study provides a promising strategy for the treatment of CRC.

ABSTRACT

With the deepening of China's medical reform, the scale of hospital equipment assets at all levels is also expanding. In the face of large-scale and various equipment assets, the traditional single machine statistical management method not only has a single interface, poor data accuracy and is not compatible with other systems, but also is difficult to achieve "full life cycle" management. In order to solve above problems, the Ninth People's Hospital Affiliated to Shanghai Jiao Tong University of Medicine aims to use the Internet of Things to build a medical equipment management information platform, realize the whole hospital area, whole subject and whole process management of medical materials, and achieve the objectives of business linkage, information connectivity and data sharing between management departments and clinical departments.

ABSTRACT

Objective To analyze the spatial and temporal characteristics of hand, foot and mouth disease (HFMD) in Hunan Province from 2016 to 2020. Methods The data of HFMD in Hunan Province from 2016 to 2020 were collected from China's Disease Prevention and Control Information System. HFMD spatial autocorrelation analysis was conducted by ArcGIS 10.2 software at county level, and spatial-temporal scan statistical analysis was performed by SaTScan 9.7 software. Results A total of 714 157 cases was reported in Hunan Province during 2016-2020, with an average annual incidence rate of 208.36/100 000. Global spatial autocorrelation showed that HFMD had a positive spatial correlation on the county scale in Hunan Province during this period. Local spatial autocorrelation indicated that the hot spots were mainly concentrated in the north of central Hunan, the east of central Hunan and the west of Hunan. Spatial-temporal scanning analysis revealed the first class clusters (RR = 6.65, P< 0.001) covering 34 counties in northern and central Hunan, mainly distributed in Yueyang City, Changsha City, Zhuzhou City, Yiyang City and Xiangtan City from May 2018 to June, and the second class clusters (RR = 3.02, P < 0.001) covering 40 counties in western Hunan and central and southwest Hunan from April 2016 to June 2016. Conclusion HFMD incidence exhibits seasonal and regional characteristics in Hunan Province. The prevention and control of HFMD should be guided by combining the characteristics of spatial-temporal clustering.

ABSTRACT

Objective:To investigate the safety and efficacy of transcatheter genicular artery embolization (GAE) for moderate to severe knee osteoarthritis (KOA).Methods:This prospective study included 13 patients (17 knees) with KOA who were treated with GAE from October 2020 to March 2021. The Kellgren-Lawrence (K-L) grade was 2-3 for 11 knees, and 4 for 6 knees. The Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and the Whole-Organ Magnetic Resonance Imaging Score (WORMS) assessments were performed for all the subjects before operation. The success rate, clinical efficacy and complications were recorded after operation. Clinical outcomes were evaluated at 1 day, 1week and 1, 3, 6 months after the operation.Results:The success rate of GAE in 17 cases was 100%, and the success rate of target artery superselection was 98.4%(63/64). The baseline WOMAC pain score was 11(10, 13) and total score was 44(38, 58) for 17 knees. Post-operation follow-up WOMAC pain score were 4(3, 7), 2(1, 5), 2(1, 6) and 4(2, 6) at 1 day, 1 week, 1 month, and 3 months. Post-operation follow-up WOMAC total score were 22 (15, 34),20 (12, 24),17 (12, 26) and 20 (12, 31) at 1 day, 1 week, 1 month, and 3 months. There were 16 knees with 6 month follow-up assessment, with the WOMAC pain score of 2.5(2, 5), and the total score of 15(12, 26). Significant difference was found in the WOMAC pain score between baseline and the 1 day, 1 week, 1, 3 and 6 months follow up ( Z=-3.631, -3.623, -3.622, -3.622, -3.532, all P<0.001); also, the total score was statistically significant different between the baseline and the 1 day, 1 week, 1, 3 and 6 months follow up ( Z=-3.639, -3.634, -3.646, -3.527, -3.532, all P<0.001). At 3 months follow-up, there was 1 knee recognized clinical failure. Post-operative adverse reaction in this group included skin ecchymosis in femoral artery puncture area ( n=3), knee joint stiffness and pain within 1 week ( n=4),and clanging joints during postoperative activities ( n=6). Conclusion:GAE is a feasible and safe procedure with obvious short-term curative effect, which can alleviate pain symptoms and improve restricted movement in patients with KOA.

ABSTRACT

Objective:To compare the advantages and disadvantages of hemiarthroplasty (HA) and reverse shoulder arthroplasty (RSA) in the treatment of complex proximal humeral fractures in the elderly patients.Methods:Pubmed, the Cochrane Library, EMBASE, and Chinese databases like CNKI, Wanfang Data and Weipu were searched for studies comparing HA and RSA in the treatment of complex proximal humeral fractures in the elderly (>60 years) from 2000 to 2020. After the studies were included and excluded by a set of inclusion and exclusion criteria and evaluated for their quality, their radiological and functional data were extracted and analyzed using software Stata 14.0.Results:Included in this meta-analysis were 11 studies with a total of 771 patients. RSA was superior to HA in outcomes like forward flexion ( SMD=-1.043, 95% CI: -1.551 to -0.534, P=0.000), abduction ( SMD=-0.811, 95% CI: -1.470 to -0.153, P=0.016), Constant score ( SMD=-0.699, 95% CI: -1.118 to -0.280, P=0.001), American Shoulder Elbow Surgeons’ Form (ASES) ( SMD=-0.931, 95% CI: -1.256 to -0.606, P<0.001), and Simple Shoulder Test (SST) ( SMD=-0.598, 95% CI: -1.181 to -0.016, P=0.044). HA led to a higher complication rate ( RR=2.14, 95% CI: 1.11 to 4.14, P=0.024), a higher joint stiffness rate ( RR=6.467,95% CI: 1.923 to 21.755, P=0.003) and a higher revision rate ( RR=5.796, 95% CI: 1.927 to 17.434, P=0.002). There were no statistically significant differences between RSA and HA in tuber healing rate ( RR=0.850, 95% CI: 0.669 to 1.080, P=0.182), internal rotation ( SMD=0.536, 95% CI: -0.394 to 1.466, P=0.259), external rotation ( SMD=-0.366, 95% CI: -0.916 to 0.184, P=0.192), implant infection ( RR=1.550, 95% CI: 0.330 to 7.286, P=0.579) or Disabilities of the Arm, Shoulder and Hand (DASH) score ( SMD=0.286, 95% CI: -0.278 to 0.850, P=0.032). Although there was no significant difference between RSA and HA in visual analogue scale (VAS) score ( SMD=0.440, 95% CI: -0.113 to 0.993, P=0.119), RSA scored better ( SMD=-1.101, 95% CI: -2.090 to -0.112, P=0.029). Conclusion:For elderly patients (>60 years) with complex proximal humeral fracture, RSA may be a more effective surgical intervention which can lead to better early and mid-term clinical outcomes than HA.

OBJECTIVE:To prepare Liguatrazine opthalmic liposome therm osensitive gel ,and to investigate its in vivo and in vitro characteristics. METHODS :The ammonium sulfate gradient method was used to prepare Liguatrazine liposomes. The preparation technology was optimized by using orthogonal test. Using poloxamer P 407 as gel matrix ,Liguatrazine liposomes were prepared into thermosensitive gel. A membraneless model was used to study the dissolution and in vitro drug release of the gel. The modified Franz diffusion cell was used to investigate corneal permeability and further determine corneal hydration value. The effects of the gel on the proliferation of human corneal epithelial cell HCE-T. HE staining and Draize test were used to investigate the stimulatory effects of the gel on corneal cells of the rabbit ,and the histological changes of the eyes were observed. RESULTS :The optimal preparation technology of Liguatrazine liposome was drug-lipid ratio of 1 ∶ 10(m/m),the ammonium sulfate concentration of 0.2 mol/L,phospholipid-cholesterol ratio of 4∶1(m/m),incubation temperature of 45 ℃. Then ligustrazine opthalmic liposome thermosensitive gel was prepared with 23% poloxamer P 407 as gel matrix. The gel had good gelatinization temperature. The in vitro drug release and dissolution showed zero-order kinetic characteristics ,and in vitro drug release of the gel was mainly related to dissolution (R2=0.993 4). The cumulative transcorneal permeability of the gel was 43.3% within 6 hours and corneal hydration value was 72.98%. Low and medium concentrations (1,5 mg/L)of Ligustrazine opthalmic liposome thermosensitive gel had no obvious proliferation toxicity to HCE-T cells ,but it showed cytotoxicity at high concentration (10 mg/L). The mean Draize eyeirritation score of the gel on rabbit cornea was within non-stimulation,and there was no abnormal change in rabbit (No.2018001) corneal histology. CONCLUSIONS : Prepared Ligustrazine opthalmic liposome thermosensitive gel has a suitable phase transition temperature ,good corneal permeability ,and low corneal irrit ation.

ABSTRACT

@#Objective    To prepare platelet-derived growth factor receptor β (PDGFRβ)-targeted near-infrared molecular probe and evaluate its potential in optical molecular imaging of lung cancer. Methods    PDGFRβ-specific affibody Z-tri was recombinantly expressed in Escherichia coli (E. coli) and purified using affinity chromatography. In vitro cell-binding of Z-tri was analyzed by flow cytometry. Cellular distribution of Z-tri in tumor grafts was determined by protein-tracing. The molecular probe CF750-Z-tri was prepared by conjugating near-infrared fluorescent dye CF750 to Z-tri. The optical images of xenografts of lung cancer were obtained by using CF750-Z-tri combined with optical imaging system. Results    PDGFRβ-specific affibody Z-tri was highly expressed in E. coli and purified to homogeneity. Z-tri could bind PDGFRβ-positive cells but not PDGFRβ-negative cells cultured in vitro. In the tumor xenografts of human lung cancer, intravenously injected Z-tri was predominantly distributed on cells overexpressing PDGFRβ. The near infrared fluorescent dye CF750 was efficiently conjugated to Z-tri. Optical images with high contrast of lung cancer xenografts were produced by using the near-infrared fluorescent probe CF750-Z-tri combined with optical imaging system. Conclusion    The near-infrared fluorescent probe CF750-Z-tri can be used for optical imaging of human lung cancer, which takes great potential in optical imaging-guided surgery of lung cancer.

ABSTRACT

Objective:To systematically evaluate the efficacy and safety of neoadjuvant chemoradiotherapy (NCRT) plus surgery versus neoadjuvant chemotherapy (NCT) plus surgery in the treatment of advanced esophageal squamous cell carcinoma.Methods:Clinical controlled trials of comparing the treatment of NCRT plus surgery with NCT plus surgery for esophageal squamous cell carcinoma were electronically searched from the databases including PubMed, The Cochrane Library, EMbase, CBM, CNKI, WanFang and VIP from the inception of databases to January, 2019. Two reviewers independently screened the literatures, extracted data and assessed the risk of bias of the included studies. And then, a meta-analysis was performed by using RevMan 5.3 software.Results:A total of 8 clinical control studies were included, including 995 patients with esophageal squamous cell carcinoma. Meta-analysis results showed that compared with the NCT group, the R 0 resection rate was significantly higher ( OR=2.14, 95% CI: 1.03-4.45, P=0.040) and the pathological complete response (pCR) rate was significantly higher ( OR=4.19, 95% CI: 1.71-10.28, P=0.002) in the NCRT group. The incidence of postoperative complications ( OR=1.37, 95% CI: 0.76-2.48, P=0.300) and the risk of perioperative death ( OR=1.28, 95% CI: 0.58-2.83, P=0.54) were not significantly different between two groups. The long-term survival of patients with esophageal squamous cell carcinoma in the NCRT group was significantly better compared with that in the NCT group ( HR=0.77, 95% CI: 0.64-0.92, P=0.005). Conclusions:Compared with NCT plus surgery for advanced esophageal squamous cell carcinoma, NCRT plus surgery has higher R 0 resection rate and pCR rate, does not significantly increase the risk of perioperative complications or perioperative death, and significantly improves the long-term survival of esophageal squamous cell carcinoma patients.

ABSTRACT

Acute respiratory distress syndrome (ARDS) is a common clinical critical disease, characterized by progressive respiratory distress, intractable hypoxemia, respiratory failure and so on, with high mortality rate and lack of effective prevention and treatment strategies. In recent years, mesenchymal stem cell (MSC) can be used in the treatment of acute lung injury (ALI), which cannot only replace the damaged lung epithelial cells, but also promote tissue repair and alleviate ARDS by secreting anti-inflammatory and anti-fibrosis factors. This review focuses on the related mechanisms and signal pathways of MSC and its paracrine factors in the treatment of ARDS by regulating the balance of macrophage polarization.

ABSTRACT

Malignant tumor, an important factor threatening human life and health, brings huge economic burden to patients. At present, chemoradiotherapy is still the main treatment method for tumor diseases, but there are also great side effects when it plays a therapeutic role. Traditional Chinese medicine in the prevention and treatment of tumor diseases has many advantages such as few side effects, improving the physiological state of patients, and slowing down the side effects of radiotherapy and chemotherapy. Berberine is an effective component of rhizoma coptidis, with a very good antitumor effect. It can inhibit tumor cell proliferation, promote tumor cell apoptosis, inhibit tumor metastasis and angiogenesis, regulate tumor autophagy, reverse multi-drug resistance of tumor, regulate the body immunity, and affect tumor metabolic reprogramming to play its role. Compared with chemical preparations, berberine has a wide range of sources, with high safety and easy access, and has great potential in the prevention and treatment of malignant tumors. In this article, we would mainly review the research progress on the antitumor mechanism of berberine in recent years.

ABSTRACT

Objective:To explore the mechanism of motor imagery training (MIT) combined with conventional rehabilitation to promote the functional recovery of upper limbs in stroke survivors. To explore the brain network reorganization resulting when motor imagery training (MIT) is combined with conventional rehabilitation to promote the motor recovery of stroke survivors.Methods:Fourteen hemiplegic patients were recruited as the MIT group. They underwent 4 weeks of MIT (30 min/day, 5 days/week) along with conventional rehabilitation treatment. The upper limb section of the Fugl-Meyer assessment (FMA-UE) and the modified Barthel Index (MBI) were used to assess all of the patients, and resting-state fMRI was performed before and after the treatment. Twenty-eight age- and sex-matched healthy subjects also received one-time resting-state fMRI scanning. Granger causal analysis was performed in the MIT group to calculate the changes in effective connection between the ipsilesional primary motor cortex and the whole brain before and after the treatment, and the results were compared with the healthy control group.Results:After the treatment, the average FMA-UE and MBI of the MIT group had increased significantly. Before the intervention, the effective connection mode of the ipsilesional M1 area in the MIT group was significantly different from that of the healthy controls. The causal flow from the ipsilesional M1 area to the bilateral prefrontal cortex had increased abnormally and the causal flow from the contralesional primary motor cortex, the inferior parietal lobule and the cerebellum to the ipsilesional M1 area had decreased significantly. After the treatment, the effective connection pattern of the stroke survivors was nearly normal, and the causal influence from contralesional motor imagery-related brain areas (the superior parietal lobule, inferior parietal lobule, thalamus and the fusiform gyrus) to the ipsilesional M1 area was enhanced. Effective connection from the ipsilesional M1 area to the contralesional cerebellum before the intervention was positively correlated with the improvement in FMA-UE scores, and the effective connection from the contralesional middle frontal gyrus to the ipsilesional M1 area was correlated negatively.Conclusions:The neural mechanism of MIT's effectiveness when it is combined with conventional rehabilitation might be related to the reorganization of effective connections. That would include enhanced causal flow between motor imagery-related brain areas and the contralesional cerebellum and ipsilesional M1 area. Down-regulation of the effective connection from the contralesional middle frontal gyrus to the ipsilesional M1 area also occurs.

ABSTRACT

Objective:To investigate optimal antiplatelet therapy options based on the CYP2C19 genotype in elderly patients with acute coronary syndrome(ACS).Methods:Elderly patients with ACS admitted to our hospital from January 2018 to March 2019 were enrolled and received CyP2C19 gene testing.Patients with the intermediate metabolic genotype of CYP2C19 were randomly divided into two groups: the Ticagrelor group and the double-dose Clopidogrel group.After a one-year follow-up, the risk of bleeding and incidences of cardiovascular events in the two groups were analyzed.Results:468 elderly patients meeting the criteria, 214 had the intermediate metabolic genotype of CYP2C19, accounting for 45.7% of the total, and were randomly divided into the ticagrelor treatment group( n=107)and the double-dose Clopidogrel treatment group( n=107). There were significant differences between the Ticagrelor treatment group and the double-dose Clopidogrel treatment group in incidences of minor bleeding, massive hemorrhage, recurrent angina and recurrent acute myocardial infarction(11.2% vs.22.4%, 2.8% vs. 9.4 %, 4.7% vs.13.1%, 3.7% vs. 11.2%, P<0.05). The double-dose Clopidogrel group not only had a higher risk of cardiovascular events, but also a higher risk of bleeding. Conclusions:For elderly ACS patients with the intermediate metabolic genotype of CYP2C19, a standard dose of ticagrelor is recommended.

Methods Thirteen cases of CVD patients from Jan 2015 to Mar 2018 admitted into the First Affiliated Hospital of Zhejiang University were retrospectively analyzed. All of them underwent digital subtraction angiography (DSA) to clarify problem origin. Suitable balloons were chosen to dilate the original catheters or the occlusive veins, and then the original catheters were replaced. PTA was used to help catheter replacement and all patients were followed up for 6 months. Results Four of the 13 patients were found stuck when replacing catheters. All of them successfully had catheters removed with PTA (Hong's techniques). All patients had successfully catheter replacement with blood flow volume>250 ml/min. Among 4 patients with edema, 3 patients showed better within 6 months. Only 3 patients needed warfarin to keep blood flow volume>250 ml/min within 6 months. Conclusions PTA shows advantages of lesser trauma, better tolerance and higher success rate in patients with catheter-related CVD. It can also relieve symptoms resulting from occlusive central vein.
