OBJECTIVETo explore the current application and features of Aconite prescriptions with incompatible herbs in grade A class three hospitals in east China and central China through a clinical study and comparative analysis.

METHODClinical prescriptions containing Aconite with incompatible herbs were collected. Association rules were utilized to analyze the compatible features of these herbs.

RESULTThis analysis found that the frequently used incompatible herba; pairs are Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma, with the support rate of 44.45%, occupying nearly half of the surveyed prescriptions; Pinelliae Rhizoma is the most frequently used herb in the two areas, with support rate up to 76.24%. Among the top 10 herbal pairs in the support rate, except for Aconiti Lateralis Radix Praeparata and Pinelliae Rhizoma, the top 10 herbs in Central China were mostly for warming the middle jiao and tonifying qi, such as Zingiberis Rhizoma, Atractylodis Macrocephalae Rhizoma and Codonopsis Radix; Whereas those in east China were mostly for activating and nourishing blood, such as Angelicae Sinensis Radix, Chuanxiong Rhizoma, and Salviae Miltiorrhizae Radix et Rhizoma. Among the top 10 herbal pairs in the support rate, except for Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma, the core herbal pairs applied in central China were mainly for resolving phlegm and warming the middle jiao, such as Pinelliae Rhizoma-Glycyrrhizae Radix et Rhizoma, Pinelliae Rhizoma-Zingiberis Rhizoma; Whereas those in east China were principally for activating blood and tonifying qi, like Atractylodis Macrocephalae Rhizoma and Pinelliae Rhizoma, Angelicae Sinensis Radix and Pinelliae Rhizoma. Among the core herbal groups in the two areas, the most frequently used herbal groups in the two areas are Aconiti Lateralis Radix Praeparata, Glycyrrhizae Radix et Rhizoma and Pinelliae Rhizoma with the support rate of 59.73%, accounting for the highest proportion among all of herbal groups.

CONCLUSIONThere are the combined clinical application of Aconite with incompatible herbs, mostly with Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma, but with differences in the combined application in east China and central China.

Reactive oxygen species (ROS) is defined as the electron reduction product of oxygen with high reactivity which can maintain normal physiological functions and redox homeostasis. The tumor microenvironment is in a state of oxidative stress. ROS can affect multiple processes of tumor immune response by modulating the phenotype and functions of tumor cells and immune cells. With the rapid development of immunology, ROS-based tumor immunomodulation has been widely concerned and studied. In this review, the mechanism of ROS participating in tumor immune response is elaborated. Meanwhile, the research process and application of ROS in tumor immunomodulation in recent years are reviewed and analyzed.

OBJECTIVETo study the flavanoids extracted from onion on the blood-brain barrier (BBB) permeation, and their effects on primary cultured neuron cell proliferation and apoptosis of SD rats using ethanol reflux method.

METHODSThe brain microvascular endothelial cells (BMVECs) were first successfully primary cultured. Then rats BMVECs and astrocytes (ACs) were co-cultured to establish the in vitro BBB model. The flavanoids were extracted from onion using ethanol reflux method. The model was verified by transmission electron microscopy (TEM) and trans-epithelial electric resistance (TEER). The flavanoids permeability was tested using high performance liquid chromatography (HPLC). Meanwhile, rat neuron cells were cultured and exposed to H2O2 and flavanoids. Their effects on the cell proliferation and apoptosis were observed using MTT assay. The injury of neuron DNA was analyzed using single-cell gel electrophoresis (SCGE) and immunofluorescent assay.

RESULTSThe in vitro BBB model was successfully established by TEM and TEER. Results of HPLC proved flavanoids extracts could effectively permeate the BBB with the permeability of 60.58%. The extractive at 10 - 20 microg/mL showed obvious inhibition on the apoptosis of neuron cells induced by H2O2, and attenuated the injury of neuron DNA.

CONCLUSIONSThe flavanoids extracted from onion ethanol reflux method could effectively penetrate the BBB. They also showed obvious inhibition on the H2O2 induced neuron cell apoptosis and DNA injury.

OBJECTIVETo explore the distribution, combination and evolution of various syndromic etiologies of erectile dysfunction (ED) based on the syndrome etiology theory.

METHODSUsing the ED Syndromic Etiology Scale, we collected the clinical data on the Chinese medicine diagnoses of 297 cases of ED, extracted the core syndromic etiologies by analysis of principal components and factors, and analyzed the patterns of distribution, combination, and evolution of ED syndromic etiologies according to the general information of the patients.

RESULTSThrough analysis of principal components and factors, 9 core syndromic etiologies were extracted, i. e. , liver constraint with qi stagnation, kidney yin deficiency, damp-heat, liver constraint transforming into liver-fire, blood stasis, kidney yang deficiency, heart-spleen paired deficiency, qi-yin paired deficiency, and phlegm-damp. Each of these syndrome etiologies exhibited its own specific distribution patterns. Of the total number of cases studied, 51.52% had 2 or 3 core syndromic etiologies and 36.03% had only one.

CONCLUSIONIn the early stage of ED, its syndromic etiologies are usually liver constraint with qi stagnation, kidney yin deficiency, damp-heat, liver constraint transforming into liver-fire, and blood stasis. With the natural progres- sion of the disease, its syndromic etiologies gradually evolve into kidney yang deficiency, heart-spleen paired deficiency, qi-yin paired deficiency, phlegm-damp, and blood stasis, and finally into yin-yang deficiency of the heart, spleen and kidneys, combined with phlegm-damp and blood stasis.

Objective To study the clinical features and to improve the treatment on the elderly patients with brain tumor.Methods Retrospective analysis of 163 cases with brain tumor which had been confirmed by CT,MRA or pathology.Results Of all the 163 cases,121 were located in supratentorium,most of which were meningiomas and gliomas.Most patients(129 cases)had comorbidity.After operation,symptoms disappeared or obviously improved in 126 cases,moderately improved in 19 cases,and did not changed in 6 patients.Twelve cases died after operation in a month, in which 9 patients were over 75 years old.The death rate of operation was 6.1%.Conclusions It is important to know the atypical manifestation of brain tumor in the elderly,which may prevent clinical misdiagnosis and mistherapy.The perioperative management is indispensable to the prognosis of the patients.The choice of operation and medication should be in individualized.

INTRODUCTION: Associations of variations in PLA2R1 and HLA-DQA1 genes with susceptibility to idiopathic membranous nephropathy (IMN) have been well documented. Association with spontaneous remission, however, is poorly defined in the Chinese Han population. METHODS: A Chinese cohort of 117 IMN patients and 138 healthy controls were recruited between July 2009 and November 2019. Case-control studies for single-nucleotide polymorphisms (SNPs) within HLA-DQA1 (rs2187668) and PLA2R1 (rs35771982, rs4664308, rs3749117, rs3749119) genes were performed. The contributions of these polymorphisms to predict susceptibility, titre of autoantibodies against the M-type phospholipase A2 receptor (anti-PLA2R1), glomerular PLA2R1 expression, and spontaneous remission were analysed. RESULTS: We found that variations in PLA2R1 (SNPs rs35771982, rs4664308, rs3749117) were strongly associated with IMN susceptibility, while SNP (rs2187668) within HLA-DQA1 did not increase the risk of IMN. All SNPs in PLA2R1 and HLA-DQA1 were not statistically associated with anti-PLA2R1 titre, glomerular PLA2R1 expression and spontaneous remission after Bonferroni correction ( CONCLUSION This study confirms that variations in PLA2R1 (SNPs rs35771982, rs4664308, rs3749117) are risk factors for IMN. We found excellent association of serum albumin level, anti-PLA2R1 titre and glomerular PLA2R1 positivity with non-spontaneous remission in IMN.

Objective Apoptosis was induced by oxidative stress in nerve cells after cerebral ischemia. It further breaks the dy-namic balance of mitochondrial division of fusion. This study aimed to investigate the effect of butylphthalide combined with edaravone treat-ment on the dynamic change of Drp1 and Mfn2 in rats with focal cere-bral ischemia cells and its protection mechanism. Methods 96 rats were divided into 4 groups according to random number table. The 4 groups were ischemia group,butylphthalide group,edaravone group and butylphthalide combined with edaravone groups(combine group),each group divided into three subgroups(3 d,7 d,14 d). Longa-Zea suppository method is adopted to establish the middle cerebral artery occlusion(MCAO)model.Butylphthalide group,edar-avone group and combine group were injected butylphthalide(0.4 g/kg)and/or edaravone(10 mL/kg)peritoneally 2 hours before surgery and 1 day after surgery. The same volume of isotonic saline was given at the same time of the other 3 groups in ischemia group. The cerebral cortex of the left ischemic region was obtained at the day 3,7,14. The evaluation of the curative effect was evaluated with neurological function score.HE staining was used to observe the cerebral cortex neuron morphological structure,protein and mRNA lev-el of Drp1 and Mfn2 was measured by western blot and RT-PCR. Results At the day 3,7,and 14,the neurological function score was higher in ischemia group than the other 3 groups(P<0.05). Compared with the combine group at day 3,7,and 14[(1.06± 0.18),(0.82±0.13),(0.57±0.10)],the neurological function score was elevated in butylphthalide group[(2.02±0.18),(1.23± 0.13),(0.86±0.10)]and edaravone group[(2.08±0.17),(1.23±0.13),(0.85±0.12)](P<0.05). At the same time point,com-pared with the ischemia group,Drp1 protein and mRNA levels were lower in the other 3 groups(P < 0.05)while Mfn2 protein and mRNA levels were elevated(P<0.05). Compared with the butylphthalide group and edaravone group,Drp1 protein and mRNA levels were lower in combine group(P<0.05)while Mfn2 protein and mRNA levels were elevated(P<0.05). Conclusion The protective effect of edaravone combined with butylphthalide is better than single use. Its mechanism may be related to the removing of oxygen free radicals and reducing oxidative stress by edaravone,and the protection of the mitochondria by butylphthalide.

To investigate the crucial role of particle size in the biological effects of nanoparticles, a series of mesoporous silica nanoparticles (MSNs) were prepared with particle size gradients (50, 100, 150, 200 nm) with the traditional Stober method and adjusting the type and ratio of the silica source. The correlation between toxicity and size-caused biological effects were then further examined both in vitro and in vivo. The results indicated that the prepared MSNs had a uniform size, good dispersal, and ordered mesoporous structure. Hemolytic toxicity was found to be independent of particle size. At the cellular level, MSNs with smaller particle sizes were more readily internalized by cells, which initiated to more intense oxidative stress, therefor inducing higher cytotoxicity, and apoptosis rate. In vivo studies demonstrated that MSNs primarily accumulated in the liver and kidneys of mice. Pharmacokinetic analysis revealed that larger MSNs were eliminated more efficiently by the urinary system than smaller MSNs. The mice's body weight monitoring, blood tests, and pathological sections of major organs indicated good biocompatibility for MSNs of different sizes. Animal welfare and the animal experimental protocols were strictly consistent with related ethics regulations of Zhejiang Chinese Medical University. Overall, this study prepared MSNs with a particle size gradient to investigate the correlation between toxicity and particle size using macrophages and endothelial cells. The study also examined the biosafety of MSNs with different particle sizes in vivo and in vitro, which could help to improve the safety design strategy of MSNs for drug delivery systems.

Objectives: To evaluate the clinical characteristics and prognosis of high risk cytogenetic abnormalities (HRCA) and various combinations of cytogenetic abnormality in patients with newly-diagnosed multiple myeloma (NDMM) . Methods: This retrospective study collected 182 NDMM patients in the First Affiliated Hospital of Jilin University between Nov. 2009 and May 2018. HRCA included 1q+, del (17p) , t (4;14) , and t (14;16) detected by FISH, and non-HRCA included del (13q) , t (11;14) detected by FISH. The clinical characteristics among three groups, including cases who carrying a single HRCA, 1 HRCA in combination with non-HRCA and cases carrying two or more HRCAs (double/triple-hit) were observed. Kaplan-Meier curve was used to analyze both progression-free survival (PFS) and overall survival (OS) for the three groups. Results: The survivals of patients with 1 HRCA in combination with non-HRCA were similar to those with two or more HRCAs (double/triple-hit) , the median PFS (mPFS) was 19.1 m vs 12.1 m (P=0.248) and median OS (mOS) was 29.6 m vs 29.3 m (P=0.774) . Furthermore, the prognosis of these two groups were both inferior to patients with a single HRCA, respectively. (mPFS: 32.2 m, P=0.040, P=0.001; mOS: 42.3 m, P=0.021, P=0.041) . Strikingly, both the mPFS and the mOS of patients with 1 HRCA in combination with non-HRCA (regardless of high risk or not) were significantly shorter than that of cases with a single HRCA (mPFS: 15.1 m vs 32.2 m, HR=2.126, 95%CI 1.176-3.843, P=0.005; mOS: 29.3 m vs 42.3 m, HR=1.442, 95%CI 0.705-2.950, P=0.011) . Conclusion: It is of prognostic significance value for detecting double/triple-hit based on FISH cytogenetics in NDMM.
