Objective:To evaluate the efficacy of Zhongfeng Xingnao liquid combined with conventional treatment for acute ischemic stroke (AIS).Methods:A total of 92 patients with AIS in our hospital from May 2020 to March 2021 who met the inclusion criteria were selected and divided into 2 groups according to the end number of the medical records, with 46 cases in each group. Both groups were given conventional western medicine therapy, and the control group added intravenous drip of edaravone injection, and the study group added Zhongfeng Xingnao liquid on the basis of the control group. Both groups were treated continuously for 2 weeks. Before and after treatment, the National Institutes of Health Stroke Scale (NIHSS) and the modified Rankin Scale (mRS) were used to evaluate the degree of neurological deficit and prognosis. The whole blood high-shear viscosity, hematocrit, whole blood low-shear viscosity, fibrinogen were detected by automatic blood rheometer, and the levels of high-sensitivity C-reactive protein (hs-CRP), IL-6 and endothelin-1 (ET-1) were detected by ELISA. Adverse events were recorded, and clinical effect rate was evaluated.Results:After treatment, the mRS score (2.06±0.18 vs. 2.73±0.23, t=15.56) and NIHSS score (5.25±2.36 vs. 10.61±2.48, t=14.58) of the study group were significantly lower than those in the control group ( P<0.01). The total clinical effective rate was 89.1% (41/46) in the study group and 69.6% (32/46) in the control group, with a statistically significant difference between the two groups ( χ2=5.37, P=0.020). After treatment, the serum levels of hs-CRP [(9.04±1.98)mg/L vs. (14.36±2.09)mg/L, t=12.57], IL-6 [(23.14±1.46)ng/L vs. (39.37±2.51)ng/L, t=12.39] and ET-1[(67.18±13.22)ng/L vs. (98.14±22.29)ng/L, t=19.37] in the study group were significantly lower than those in the control group ( P<0.01). The whole blood high shear viscosity [(7.53± 1.37)mPa·s vs. (9.24±1.42)mPa·s, t=5.89], hematocrit [(0.27±0.06)% vs. (0.39±0.08)%, t=8.14], whole blood low shear viscosity [(5.92±1.09)mPa·s vs. (8.35±1.24)mPa·s, t=9.98] and fibrinogen [(1.63±0.42) g/L vs. (2.47±0.58) g/L, t=7.96] were significantly lower than those in the control group ( P<0.01). During the treatment period, the incidence of adverse events was 8.70% (4/46) in the control group and 15.22% (7/46) in the study group, and there was no significant difference between the two groups ( χ2=0.93, P=0.335). After treatment, the good outcome rate was 73.9% (34/46) in the control group and 93.5% (43/46) in the study group, with a statistically significant difference between the two groups ( χ2=6.45, P=0.011). Conclusion:The Zhongfeng Xingnao liquid combined with edaravone injection can reduce the level of inflammatory cytokines in patients with AIS, improve hemorheological indicators, and play a role in brain protection.

ObjectiveTo investigate the effect of Guiqi Baizhu prescription （GQBZ） combined with oxaliplatin on the expression of epidermal growth factor receptor （EGFR） and vascular endothelial growth factor receptor-2 （VEGFR2） and angiogenesis in gastric cancer-bearing mice. MethodThe tumor-bearing model of gastric cancer was induced in Kunming mice. The mice were randomly divided into blank group， model group， oxaliplatin group （10 mg·kg-1）， and high- （17.68 g·kg-1）， medium- （8.84 g·kg-1）， and low-dose （4.42 g·kg-1） combination groups （GQBZ combined with oxaliplatin）. After the last administration， the transplanted tumor was collected and the tumor inhibition rate was calculated. Hematoxylin-eosin （HE） staining was used to observe the morphological changes of tumor tissues. Enzyme-linked immunosorbent assay （ELISA） was used to detect the serum content of epidermal growth factor （EGF）， interleukin-8 （IL-8）， and vascular endothelial growth factor （VEGF）. Western blot and immunohistochemistry （IHC） were used to detect the expression of EGFR， phosphorylated EGFR （p-EGFR）， VEGFR2， phosphorylated VEGFR2 （p-VEGFR2）， and platelet-endothelial cell adhesion molecule （CD31）. Real-time fluorescence-based quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of EGFR and VEGFR2. ResultThe tumor weight in the drug intervention groups was significantly lower than that in the model group （P<0.01）. Compared with the oxaliplatin group， the high- and medium-dose combination groups showed reduced tumor weight （P<0.05， P<0.01）. The tumor cells in the model groups were high in cell density and regular in shape， and no clear tissue necrosis was seen. The tumor cell density in the drug intervention groups was reduced， and clear tissue necrosis and large-scale inflammatory cells were visible. Compared with the blank group， the model group and the drug intervention groups showed increased serum levels of EGF， VEGF， and IL-8 （P<0.05， P<0.01）. Compared with the model group， the drug intervention groups showed decreased serum levels of EGF， VEGF， and IL-8 （P<0.01）， reduced protein expression of EGFR， p-EGFR， VEGFR2， p-VEGFR2， and CD31， and declining mRNA expression of EGFR and VEGFR （P<0.01）. Compared with the oxaliplatin group， the high- and medium-dose combination groups showed decreased serum levels of EGF， VEGF， and IL-8 （P<0.05， P<0.01）， reduced protein expression of EGFR， p-EGFR， VEGFR2， p-VEGFR2， and CD31， and dwindled mRNA expression of EGFR and VEGFR2 （P<0.05， P<0.01）. The low-dose combination group showed decreased serum levels of EGF， VEGF， and IL-8， reduced protein expression of EGFR， p-EGFR， VEGFR2， p-VEGFR2， and CD31， and dwindled mRNA expression of EGFR and VEGFR2， but the difference was not statistically significant. ConclusionGQBZ combined with oxaliplatin can inhibit the growth and angiogenesis of tumor tissues in gastric cancer-bearing mice by affecting the expression of EGFR and VEGFR2.

Generation of αGal-enhanced bifunctional tumor vaccine

Hepatocellular carcinoma (HCC) is a common malignant tumor with poor prognosis and high mortality. In this study, we demonstrated a novel vaccine targeting HCC and tumor neovascular endothelial cells by fusing recombinant MHCC97H cells expressing porcine α-1,3-galactose epitopes (αGal) and endorphin extracellular domains (END) with dendritic cells (DCs) from healthy volunteers. END+/Gal+-MHCC97H/DC fusion cells induced cytotoxic T lymphocytes (CTLs) and secretion of interferon-gamma (IFN-γ). CTLs targeted cells expressing αGal and END and tumor angiogenesis. The fused cell vaccine can effectively inhibit tumor growth and prolong the survival time of human hepatoma mice, indicating the high clinical potential of this new cell based vaccine.

Preclinical evaluation and pilot clinical study of 18FAlF-labeled FAPI-tracer for PET imaging of cancer associated fibroblasts

In recent years, fibroblast activation protein (FAP) has emerged as an attractive target for the diagnosis and radiotherapy of cancers using FAP-specific radioligands. Herein, we aimed to design a novel 18F-labeled FAP tracer ([18F]AlF-P-FAPI) for FAP imaging and evaluated its potential for clinical application. The [18F]AlF-P-FAPI novel tracer was prepared in an automated manner within 42 min with a non-decay corrected radiochemical yield of 32 ± 6% (n = 8). Among A549-FAP cells, [18F]AlF-P-FAPI demonstrated specific uptake, rapid internalization, and low cellular efflux. Compared to the patent tracer [18F]FAPI-42, [18F]AlF-P-FAPI exhibited lower levels of cellular efflux in the A549-FAP cells and higher stability in vivo. Micro-PET imaging in the A549-FAP tumor model indicated higher specific tumor uptake of [18F]AlF-P-FAPI (7.0 ± 1.0% ID/g) compared to patent tracers [18F]FAPI-42 (3.2 ± 0.6% ID/g) and [68Ga]Ga-FAPI-04 (2.7 ± 0.5% ID/g). Furthermore, in an initial diagnostic application in a patient with nasopharyngeal cancer, [18F]AlF-P-FAPI and [18F]FDG PET/CT showed comparable results for both primary tumors and lymph node metastases. These results suggest that [18F]AlF-P-FAPI can be conveniently prepared, with promising characteristics in the preclinical evaluation. The feasibility of FAP imaging was demonstrated using PET studies.

Identification of Chinese medicine sea snake based on cytochrome B (Cytb) / 中国中药杂志

The identification of species primordium has been one of the hot issues in the identification of traditional Chinese medicine. Sea snake is one of the most valuable Chinese medicinal materials in China. In order to understand the origin and varieties of sea snake in the market, we studied the molecular identification of 46 sea snakes by cytochrome B(Cytb). After comparison and manual correction, the sequence length was 582 bp, and the content of A+T(58.9%) was higher than that of G+C(41.1%). There exist 197 variable sites and 179 parsimony-informative sites of the sequence. There are 44 kinds of sequence alignment with consistency equal to 100%, and 2 kinds equal to 96%. A total of 408 Cytb effective sequences were downloaded from GenBank database, with a total of 68 species. Phylogenetic tree of a total of 454 sea snake sequences with the samples in this study were constructed by neighbor-joining trees and Bayesian inference method, respectively, which can identify 42 samples of medicinal materials, while 4 samples can not be identified because of their low node support. The results showed that the species of the sea snake medicine were at least from 2 genera and 5 species, namely, Aipysurus eydouxii, Hydrophis curtus, H. caerulescen, H. curtus, H. ornatus and H. spiralis. This study suggested that the original species of commercial sea snake are very complex and can provide insight into the identification of sea snakes.

Experimental Study of Hemilaminectomy, Total Laminectomy and Recapping laminoplasty of Cervical Spine in Sheep / 医用生物力学

Objective To study the effect of hemilaminectomy, total laminectomyand recapping laminoplasty on stability of the cervical spine. Methods Fourteen fresh adult sheep cervical spine specimens were divided into two groups, with 7 cases in each group. Each specimen was applied with a pure moment load of 3.0 N·m under flexion/extension, left/right lateral bending, and left/right axial rotation. The range of motion (ROM) and neutral zone (NZ) of specimens were measured. In the first group, the ROMs and NZs of the specimens were measured and compared under the intact state, C5 hemilaminectomy state and C4-6 hemilaminectomy state respectively. In the second group, the ROMs and NZs of specimens under the intact state, C4-6 total laminectomy state and C4-6 recapping laminoplasty state were measured and compared. Results There were no significant differences in ROMs and NZs between C5 hemilaminectomy state and C4-6 hemilaminectomy state compared with the intact state (P<0.05). Compared with the intact state, ROMs of the specimens were significantly increased during flexion and extension under C4-6 laminectomy state and C4-6 recapping laminoplasty state (P<0.05). In addition, compared with the C4-6 laminectomy state, ROMs of the specimen were significantly decreased only during extension unde C4-6 recapping laminoplasty state (P<0.05), while no significant differences were found in ROMs between total laminectomy and laminoplasty under other loads. Conclusions With hemilaminectomy, ROMs and NZs of the cervical spine did not increase significantly, and stability of the cervical spine was not affected. With C4-6 total laminectomy, ROMs and NZs during flexion and extension increased significantly, and stability of the cervical spine was affected. Recapping laminoplasty did not significantly improve stability of the cervical spine with total laminectomy.

Improvement of natural product production in Streptomyces by manipulating pathway-specific regulators / 生物工程学报

Streptomyces are major sources of bioactive natural products. Genome sequencing reveals that Streptomyces have great biosynthetic potential, with an average of 20-40 biosynthetic gene clusters each strain. However, most natural products from Streptomyces are produced in low yields under regular laboratory cultivation conditions, which hamper their further study and drug development. The production of natural products in Streptomyces is controlled by the intricate regulation mechanisms. Manipulation of the regulatory systems that govern secondary metabolite production will strongly facilitate the discovery and development of natural products of Streptomyces origin. In this review, we summarize progresses in pathway-specific regulators from Streptomyces in the last five years and highlight their role in improving the yields of corresponding natural products.

Analysis of hydroxylation and O-glycosylation on lysine sites in deer-hide gelatin / 中国中药杂志

Nano-LC MS/MS was used to analyze trypsin digested deer-hide gelatin(DHG) samples, hydroxylation and O-glycosylation on lysine sites of DHG were comprehensive identified by using PEAKS Studio software. The sites, sorts and amounts of hydroxylation and O-glycosylation on Type Ⅰ collagen α1 chain(COL1 A1) and α2 chain(COL1 A2) of DHG were revealed. As a result, 5 284 peptides were identified from DHG samples, which were mainly from COL1 A1 and COL1 A2. Among these peptides, there were 449 peptides with hydroxylysine, 442 with galactosyl-hydroxylysine, 449 with glucosyl-galactosyl-hydroxylysine. The major modified sites of hydroxylation and O-glycosylation in DHG were shown as follow: α1-9 N and α2-5 N in N-telopeptides, α1-87, α1-174, α1-930, α2-87, α2-174, α2-933 in triple helix domain, and α1-16 C in C-telopeptides. These hydroxylation and O-glycosylation were correlated with the formation and stability of collagen molecules and collagen fibrils. It is feasible for the collagens and peptides dissolving from deer skin collagen fibrils under high temperature and pressure decocting, high temperature and pressure also might destroy inter-molecular covalent cross-linking and help those glycol-peptides formations. The present study provided ideas and strategies for the in-depth investigation on DHG chemical constituents, and showed good theoretical significance and application value.

Simple and robust differentiation of Ganoderma species by high performance thin-layer chromatography coupled with single quadrupole mass spectrometry QDa / 中国天然药物

In this study, a high performance thin-layer chromatography/single quadrupole mass spectrometry QDa (HPTLC-QDa) method for robust authentication of Ganoderma lucidum, a popular and valuable herbal medicine, has been developed. This method is simple and practical, which allows direct generation of characteristic mass spectra from the HPTLC plates automatically with the application of in situ solvent desorption interface. The HPTLC silica gel plates were developed with toluene-ethyl formate-formic acid (5 : 5 : 0.2, V/V) and all bands were transferred to QDa system directly in situ using 80% methanol with 0.1% formic acid as desorption solvent. The acquired HPTLC-QDa spectra showed that luminous yellow band b3, containing ganoderic acid B/G/H and ganodeneric acid B, the major active components of Ganoderma, could be found only in G. lucidum and G. lucidum (Antler-shaped), but not in G. sinense and G. applanatum. Moreover, bands b13 and b14 with m/z 475/477 and m/z 475/491/495, respectively, could be detected in G. lucidum (Antler-shaped), but not in G. lucidum, thus allowing simple and robust authentication of G. lucidum with confused species. This method is proved to be simple, practical and reproducible, which can be extended to analyze other herbal medicines.

The 3-year cumulative incidence of RR and NRM rates were (13.9±0.1) % and (22.2±0.1) %, respectively. ②Univariate analysis showed that patients with grade Ⅲ-Ⅳ acute graft-versus-host disease (aGVHD) or hematopoietic cell transplantation comorbidity index (HCT-CI) ≥2 points or patients in very high-risk group of the Revised International Prognostic Scoring System (IPSS-R) had significantly decreased OS[ (42.9±13.2) %vs (72.9±4.2) %, χ2=8.620, P=0.003; (53.3±7.6) %vs (72.6±4.7) %, χ2=6.681, P=0.010; (53.8±6.8) %vs (76.6±6.2) %vs (73.3±7.7) %, χ2=6.337, P=0.042]. For MDS patients with excess blasts-2 (MDS-EB2) and acute myeloid leukemia patients derived from MDS (MDS-AML) , pre-transplant chemotherapy or hypomethylating agents (HMA) therapy could not improve the OS rate[ (60.4±7.8) %vs (59.2±9.6) %, χ2=0.042, P=0.838]. ③Multivariate analysis indicated that the HCT-CI was an independent risk factor for OS and DFS (P=0.012, HR=2.108, 95%CI 1.174-3.785; P=0.008, HR=2.128, 95%CI 1.219-3.712) .@*Conclusions@#HCT-CI was better than the IPSS-R in predicting the outcomes after transplantation. The occurrence of grade Ⅲ-Ⅳ aGVHD is a poor prognostic factor for OS. For patients of MDS-EB2 and MDS-AML, immediate transplantation was recommended instead of receiving pre-transplant chemotherapy or HMA therapy.

One patient with poor healing of sinus after implant of vascular prosthesis due to infected abdominal aortic aneurysms treated with negative pressure wound therapy combined with local flap / 中华烧伤杂志

In February 2018, a 67-year-old male patient with infected abdominal aortic aneurysm was admitted to the Department of Vascular Surgery of Yantai Yuhuangding Hospital Affiliated to Qingdao University Medical College. After admission, abdominal aortic endovascular exclusion surgery, right iliac artery-double femoral artery vascular bypass+ infected abdominal aortic aneurysmectomy+ stent removal surgery, and active anti-infective treatment were performed in the department of vascular surgery. Seven days after the vascular prosthesis bypass surgery, the surface skin of the vascular prosthesis of the patient was red and swollen, and there was a purulent discharge, which was diagnosed as poor healing of sinus of vascular prosthesis. Surgeons of our department and the department of vascular surgery performed incision and debridement of sinus of vascular prosthesis+ vacuum sealing drainage (VSD) in the early stage under local anesthesia. After the local infection was controlled and wound blood supply was improved, stage Ⅱ surgery of resection of sinus of vascular prosthesis+ vascular prosthesis partial diversion+ local flap propulsion under general anesthesia was performed. The incision healed well after surgery, and the patient was discharged smoothly. During the follow-up of 6 months, the patient′s flap was in good shape, and the wound was healed. This case prompts that after the diagnosis of infected abdominal aortic aneurysm vascular sinus poor healing, we can actively open the infected sinus, use VSD technology to treat granulation wounds, then divert the implanted vascular prosthesis to prepare fresh local flap which covers the vascular prosthesis, and use new silver ion dressing to cover the wounds, thus achieving satisfactory results.
