Objective: To assess the prevalence, risk factors and treatment of anemia in patients with chronic kidney disease (CKD). Methods: A descriptive method was used to analyze the prevalence and treatment of anemia in CKD patients based on regional health data in Yinzhou District of Ningbo during 2012-2018. The multivariate logistic regression analysis was used to identify independent influence factors of anemia in the CKD patients. Results: In 52 619 CKD patients, 15 639 suffered from by anemia (29.72%), in whom 5 461 were men (26.41%) and 10 178 were women (31.87%), and anemia prevalence was higher in women than in men, the difference was significant (P<0.001). The prevalence of anemia increased with stage of CKD (24.77% in stage 1 vs. 69.42% in stage 5, trend χ2 test P<0.001). Multivariate logistic regression analysis revealed that being women (aOR=1.57, 95%CI: 1.50-1.63), CKD stage (stage 2: aOR=1.10, 95%CI: 1.04-1.16;stage 3: aOR=2.28,95%CI: 2.12-2.44;stage 4: aOR=4.49,95%CI :3.79-5.32;stage 5: aOR=6.31,95%CI: 4.74-8.39), age (18-30 years old: aOR=2.40,95%CI: 2.24-2.57, 61-75 years old: aOR=1.35,95%CI:1.28-1.42, ≥76 years old: aOR=2.37,95%CI:2.20-2.55), BMI (<18.5 kg/m2:aOR=1.29,95%CI: 1.18-1.41;23.0-24.9 kg/m2:aOR=0.79,95%CI: 0.75-0.83;≥25.0 kg/m2:aOR=0.70,95%CI: 0.66-0.74), abdominal obesity (aOR=0.91, 95%CI: 0.86-0.96), chronic obstructive pulmonary disease (aOR=1.15, 95%CI: 1.09-1.22), cancer (aOR=3.03, 95%CI: 2.84-3.23), heart failure (aOR=1.44, 95%CI: 1.35-1.54) and myocardial infarction (aOR=1.54, 95%CI:1.16-2.04) were independent risk factors of anemia in CKD patients. Among stage 3-5 CKD patients with anemia, 12.03% received iron therapy, and 4.78% received treatment with erythropoiesis-stimulating agent (ESA) within 12 months after anemia was diagnosed. Conclusions: The prevalence of anemia in CKD patients was high in Yinzhou. However, the treatment rate of iron therapy and ESA were low. More attention should be paid to the anemia management and treatment in CKD patients.

The role of γ-aminobutyric acid in tumor immunity / 药学学报

italic>γ-Aminobutyric acid (GABA) is a crucial inhibitory neurotransmitter found in various cells in the human body. While the GABAergic system is typically associated with the nervous system, recent research has revealed that immune cells and tumor cells also express components of this system. In the tumor microenvironment (TME), GABA is secreted to act extracellularly on other cells. GABA is metabolized via the GABA shunt and is involved in the tricarboxylic acid (TCA) cycle by generating succinate, which can provide energy for tumor cells. Activation of GABA receptors (GABARs) is a major pathway through which GABA participates in the regulation of antitumor immune responses. The activation of GABA type A receptors (GABAARs) can inhibit the activation and proliferation of T cells, elicit anti-inflammatory macrophages, and promote tumor cell growth and migration, while activation of GABA type B receptors (GABABRs) is generally considered to inhibit cancer cell migration and induce cancer cell apoptosis. In general, receptor activation inhibits immune cells, but the effect on tumor cells varies. Additionally, the downregulation of the expression levels of GABA transporters (GATs) is involved in tumor progression. Although antagonists of GABA metabolism and drugs that act on GABA receptors are considered therapeutic drugs for tumors, there have been few clinical studies conducted on them.

Efficacy of ultra-mini percutaneous nephrolithotomy and retrograde intrarenal surgery in the treatment of 2-3 cm lower calyceal stones / Eficacia de la nefrolitotomía percutánea ultramini y la cirugía intrarrenal retrógrada en el tratamiento de cálculos caliceales inferiores de 2-3 cm

Abstract We aimed to compare the efficacy and safety of ultra-mini percutaneous nephrolithotomy (UMP) and retrograde intrarenal surgery (RIRS) for the management of lower calyceal stones. A group of 136 patients with a single lower calyceal stone (2-3 cm in diameter) was divided into the UMP or RIRS groups. The average operation time in the RIRS group was significantly longer than that in the UMP group, and the intraoperative blood loss in the former was markedly less than that in the latter. Besides, in the RIRS group, the decreased value of postoperative Hb was obviously lower, the postoperative hospital stay was evidently shorter, and the total hospitalization expenses were markedly less than those in UMP group were. Moreover, the success rate of the first-stage lithotripsy in the UMP group was notably higher than that in RIRS group. The RIRS group had an obviously lower VAS score but a markedly higher BCS score than the UMP group six hours after surgery. At 24 h after operation, the levels of serum CRP, TNF-α and IL -6 in patients in both groups were remarkably increased, and they were evidently lower in the RIRS group than those in the UMP group were. Three days after surgery, the levels of serum CRP, TNF-α and IL -6 were notably lower in the UMP group than those in RIRS group were. RIRS and UMP are safe and effective in the treatment of 2-3 cm lower calyceal stones. The first-stage UMP is characterized by a high stone-free rate (SFR), short operation time and low postoperative infection risk, while RIRS is associated with less blood loss and low total expenses.

Analysis of Gene Mutation Characteristics and Prognosis of Elderly Patients with Acute Myeloid Leukemia / 中国实验血液学杂志

OBJECTIVE@#To investigate the characteristics of gene mutation in elderly patients with acute myeloid leukemia (AML) and its effect on prognosis.@*METHODS@#The clinical and laboratorial characteristics of 54 AML patients (≥60 years old) in Department of Hematology, Tangdu Hospital were analyzed retrospectively during April 2016 to October 2019. Thirty-four AML/myelodysplastic syndrome/myeloproliferative neoplasm related mutant genes were detected by second-generation sequencing technology, and their clinical characteristics, treatment effect, and influence on prognosis were analyzed.@*RESULTS@#All the patients received DAC+CAG induction treatment, after 1-2 couses of treatment, 36 cases (66.7%) achieved complete response, with a total effective rate of 75.9%, and the median survival time was 17 months. The most frequent mutant genes were TET2 (33.3%), CEBPA (31.5%), DNMT3A (18.5%), ASXL1 (16.7%), NRAS (14.8%), RUNX1 (14.8%), FLT3-ITD (12.9%), TP53 (12.9%), NPM1 (12.9%), and IDH2 (12.9%). Among 7 patients with TP53 mutation, 6 cases obtained complete response after 1-2 courses of induction treatment, but there was no statistically significant difference in the effect on prognosis. Patients with FLT3-ITD and NRAS mutations had shorter overall survival time compared with who had no mutation (P=0.47, P=0.48). Multivariate analysis showed that FLT3-ITD and NRAS mutations were poor prognostic factors.@*CONCLUSION@#The incidence of TET2 gene mutation is high in elderly AML patients. AML patients with TET2 and TP53 mutations may benefit from Decitabine-based chemotherapy. However, patients with FLT3-ITD and NRAS mutations have a short survival time, and may have a poor prognosis.

Mechanism of paeoniflorin inhibiting apoptosis of hippocampal neurons of rats induced by lead acetate / 中华劳动卫生职业病杂志

Objective: To investigate the effect and underlying mechanism of paeoniflorin on hippocampal neuron apoptosis induced by lead acetate. Methods: In September 2020, primary hippocampal neuronal cells were isolated and cultured from fetal rats, and identified using cellular immunofluorescent. MTT assay was used to measure the cell viability to determine the concentration and time of lead acetate-induced hippocampal neuron apoptosis. MTT was also used to evaluate the effect of paeoniflorin concentration on the apoptosis of hippocampal neurons induced by lead acetate. According to the results, different concentrations of paeoniflorin were selected to intervene hippocampal neuron cells, after 24 h, lead acetate was added to the cells, meanwhile, blank and model groups were set up, the content of reactive oxygen species (ROS) , superoxide dismutase (SOD) , lactate dehydrogenase (LDH) , malondialdehyde (MDA) and Caspase-3 were measured. Extracellular signal regulated kinase (ERK) , phosphorylated ERK (p-ERK) , p38 mitogen -activated protein kinases (p38MAPK) , phosphorylated p38MAPK (p-p38MAPK) , c-Jun N-terminal kinase (JNK) and phosphorylated JNK (p-JNK) protein expression in hippocampal neuronal cells were determined by Western blotting. Results: The isolated and cultured hippocampal neurons were identified by immunofluorescence chemical staining and then treated with lead acetate, MTT results showed that lead acetate had the best toxicity effect when treated for 24 h at a concentration of 25 μmol/L. Paeoniflorin showed no cytotoxic effect on hippocampal neuronal cells when the concentrations below 80 μmol/L. Compared with the model group, the activity of hippocampal neuronal cells was significantly increased after treating with 20, 40 or 80 μmol/L paeoniflorin (P<0.05) . Compared with the blank group, the ROS activity, LDH release level, MDA content and caspase-3 content were significantly increased (P<0.01) , and the SOD activity was significantly decreased (P< 0.01) in the hippocampal neuronal cells of the model group. Compared with the model group, the ROS activity, LDH release level, MDA content and caspase-3 content were obviously decreased (P<0.05) , SOD activity was significantly increased (P <0.01) after hippocampal neuronal cells were treated with 40 or 80 μmol/L paeoniflorin. Relative to the model group, the ratio of p-ERK/ERK were significantly up-regulated (P<0.01) , while the ratios of p-p38MAPK/p38MAPK and p-JNK/JNK were significantly down-regulated after hippocampal neuronal cells were treated with 40 or 80 μmol/L paeoniflorin (P<0.05) . Conclusion: Paeoniflorin may down-regulate the expression of p-p38MAPK and p-JNK protein, up-regulate the expression of p-ERK protein, and inhibit the apoptosis of hippocampal neurons induced by lead acetate through the MAPK signaling pathway.

Tryptophan and tumor immunity / 药学学报

As an essential amino acid, tryptophan (Trp) has various physiological functions and is of great significance in the metabolic process of tumors. In the human body, tryptophan is mainly transformed through kynurenine metabolic pathway, which not only promotes the inherent malignant properties of tumor cells, but also leads to immune-suppressive tumor microenvironment. Changes in tryptophan metabolism often occur in tumors, accompanied by abnormal gene expression of tryptophan-related enzymes, among which indoleamine 2,3-bioxygenase (IDO)-related gene expression and tryptophan 2,3-dioxygenase (TDO)-related gene changes are the most significant. A large number of clinical trials on IDO inhibitors, TDO inhibitors and combination therapy have been carried out. This paper reviewed the tryptophan metabolic pathway, regulation of IDO (TDO), kynurenine (KYN) and other related genes in tumor cells, and outlined the development of therapeutic schedule targeting tryptophan-related genes. The new progress provides new ideas for the further exploration of tumor treatment options.

The immunomodulatory effect of lactic acid within the tumor microenvironment / 药学学报

Tumor cells leads to enhanced glucose uptake and the conversion of a larger fraction of pyruvate into lactate even under the circumstance of abundant oxygen. This phenomenon of aerobic glycolysis is known as the Warburg effect. Lactic acid, as an important tool for tumor cells to modify the tumor microenvironment, promotes the process of tumor invasion and metastasis, and contributes to tumor development by inducing and recruiting immunosuppression-related cells and molecules. Lactic acid could efflux out of the cancer cells via the monocarboxylate transporters to prevent intracellular acidification. Lactate can inhibit the cytolytic activity of T cells and natural killer (NK) cells, promoting the differentiation of tolerogenic interleukin 10 (IL-10)-producing dendritic cells. Moreover, the lactate-derived lactylation of histone lysine residues can promote macrophage polarization toward the M2-like phenotype, suppressing the immune response within the tumor microenvironment. In this review, we discuss the role of lactate as an immunosuppressor molecule that contributes to tumor evasion from the aspects of lactic acid metabolism and its effect on immune cells. And we explore the possibility of targeting potential targets in lactate metabolism for tumor treatment. At last, we proposed a tumor immunotherapy strategy by inhibiting the pathway of aerobic glycolysis and proteins associated with the production and transport of lactic acid.

Effects of Nardostachys jatamansi on gut microbiota of rats with Parkinson's disease / 中国中药杂志

Under the guidance of the traditional Chinese medicine(TCM) theory of "Zangfu-organs of spleen and stomach" and the modern theory of "microbiota-gut-brain axis", this study explored the effects of Nardostachys jatamansi on the gut microbiota of rats with Parkinson's disease(PD). The 40 SD rats were randomly divided into the control group, PD model group, levodopa group, and Nardostachys jatamansi ethanol extract group. The PD model was established by subcutaneous injection of rotenone in the neck and back area. After 14 days of intragastric administration, the PD rats' behaviors were analyzed through open field test, inclined plane test, and pole test. After the behavioral tests, the striatum, colon, and colon contents of rats in each group were collected. Western blot was employed to detect the protein expression of tyrosine hydroxylase(TH) and α-synuclein(α-syn) in striatum and that of α-syn in colon. Enzyme linked immunosorbent assay(ELISA) was used to detect the levels of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), and nuclear factor-kappa B(NF-κB) in striatum and colon. High-throughput sequencing of 16 S rRNA gene was conducted to detect the differences in microbial diversity, abundance, differential phyla, and dominant bacteria of rats between groups. The results indicated that Nar. ethanol extract could relieve dyskinesia, reverse the increased levels of α-syn, TNF-α, IL-1β, and NF-κB in striatum, and improve the protein expression of TH in striatum of PD rats. The α diversity analysis indicated a significant decrease in diversity and abundance of gut microbiota in the PD model. The results of linear discriminant analysis effect size(LEfSe) of dominant bacteria indicated that Nardostachys jatamansi ethanol extract increased the relative abundance of Clotridiaceae, Lachnospiraceae, and Anaerostipes, and reversed the increased relative abundance of Proteobacteria, Gammaproteobacteria, Enterobacteriaceae, and Escherichia-Shigella in PD model group to exhibit the neuroprotective effect. In summary, the results indicated that Nar. ethanol extract exert the therapeutic effect on PD rats. Specifically, the extract may regulate gut microbiota, decrease the levels of proinflammatory cytokines, and reduce the protein aggregation of α-syn in the colon and striatum to alleviate intestinal inflammation and neuroinflammation. This study provides a basis for combining the theory of "Zangfu-organs of spleen and stomach" with the theory of "microbiota-gut-brain axis" to treat PD.

Analysis of the Electrophoretic Profiles of Prion Protein in Carcinous and Pericarcinous Lysates of Six Different Types of Cancers / 生物医学与环境科学（英文）

Objective@#To find the different electrophoretic profiles of prion protein in carcinous and individual pericarcinous tissues in lysates of gastric, colon, liver, lung, thyroid, and laryngeal cancers.@*Methods@#Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and Western blot were used to test the amounts and electrophoretic patterns of total PrP and the tolerance of PK (protease K) digestion among six various cancer tissue types.@*Results@#A mass of PrP signals with a large molecular weight were identified in the homogenates of peripheral tissues. The amounts and electrophoretic patterns of total PrP did not differ significantly between carcinous and pericarcinous tissues. PrPs in all types of the tested cancer samples were PK sensitive but showed diversity in the tolerance of PK digestion among various tissue types.@*Conclusions@#The study revealed that the included electrophoretic patterns of carcinous and pericarcinous tissues were almost similar. Unlike PrP-specific immunohistochemical assay, evaluation of PrP electrophoretic patterns in the peripheral organs and tissues by Western blot does not reflect tumor malignancy.

Research progress on diarrhea induced by molecular-targeted agents / 药学学报

In recent years, the focus of anti-cancer agents has gradually shifted from cytotoxic chemotherapy to molecular-targeted agents that interfere with frequently overexpressed or mutated molecules in cancer cells. Compared with cytotoxic chemotherapy, molecular-targeted therapy is a new biological therapy with higher specificity and lower toxicity, however, the adverse reactions caused by molecular-targeted agents cannot be ignored. Diarrhea is one of the most common adverse drug reactions, which could seriously affect the quality of life and even lead to treatment discontinuation and consequently decreased cancer control. To provide a reference for relevant research and clinical medication, we review the current reports on the incidence, pathogenic mechanism, and management of diarrhea induced by the molecular-targeted agents.

Historical Evolution and Modern Research Progress of Quality Evaluation Based on Character Identification of Traditional Chinese Medicinal Materials / 中国实验方剂学杂志

Quality evaluation based on character identification of traditional Chinese medicinal materials is the wisdom crystallization of the long-term medication experience of the pharmacists in the past dynasties， and is a quality evaluation system with the characteristics of traditional Chinese medicine （TCM）. Because of its simple language， easy to understand and easy to operate， it plays an important guiding role in the quality evaluation of TCM. Modern electronic sensory apparatus technology can realize the objective expression of TCM characters. Some scholars correlated their expression results with the contents of the main chemical components in TCM， proving that quality evaluation based on character identification of traditional Chinese medicinal materials has a certain scientific basis. However， the scientific connotation of quality evaluation based on character identification of traditional Chinese medicinal materials has not yet been clearly clarified. There is a lack of systematic research on which characters of TCM can truly reflect its quality. Therefore， the author summarizes quality evaluation based on character identification of traditional Chinese medicinal materials from three aspects. It makes clear that the idea of quality evaluation based on character identification of traditional Chinese medicinal materials is derived from analogical thinking， and combs the four stages of germination， development， prosperity and maturity experienced in its formation process， summarizes the modern research progress of this theory， clarifies that the role of the theory in evaluating the quality of medicinal materials， guiding the classification of commodity specifications， and harvesting and processing of medicinal materials. It is recommended that the follow-up should be strengthened on the research of quality evaluation based on character identification of traditional Chinese medicinal materials， make full use of electronic sensory instruments， liquid-mass spectrometry， biological efficacy evaluation and other technologies， strengthen the objective description of the characteristics of TCM， and attach importance to the analysis of the correlation between the overall characteristics of TCM and its efficacy， and establish a new research model related to the characteristics-active ingredients-pharmaceutical effects of TCM， in order to elucidate the scientific connotation of quality evaluation based on character identification of traditional Chinese medicinal materials， so as to better serve the quality evaluation of TCM.

Research progress of pneumococcal polyaccharide conjugate vaccine / 上海预防医学

Humans have been struggling for two centuries to reduce the health and economic burden caused by pneumococcal infection. Invasive pneumococcal disease （IPD）， meningitis， and acute otitis media caused by pneumococcus occur worldwide， especially in infants， children and elderly. Pneumococcus is resistant to most antibiotics and vaccines remain the most effective measure against the pneumococcal epidemic. The development of the pneumococcal vaccine was initiated at the beginning of 21 century. In 2014， incidence and mortality of pneumococcal pneumonia and IPD induced by vaccine serotypes decreased accordingly after the introduction of 13-valent pneumococcal conjugate vaccine （PCV）. Subsequently， the new challenge is to further improve the low response of some existing vaccine serotypes， include more serotypes in the PCV， and research on the application of PCV in specific populations. This review briefly describes the development of PCV.

Study on mechanism of Valerianae Jatamansi Rhizoma et Radix against post-traumatic stress disorder based on molecular docking and network pharmacology / 中国中药杂志

This paper aims to investigate the active components and mechanism of Valerianae Jatamansi Rhizoma et Radix against post-traumatic stress disorder(PTSD) based on network pharmacology and molecular docking. The main components and targets of Valerianae Jatamansi Rhizoma et Radix were obtained by literature mining methods, SwissTargetPrediction, BATMAN and ETCM database. PTSD-related genes were collected from DrugBank, TTD and CTD databases. The protein-protein interaction(PPI) network was constructed based on STRING, and the core targets of Valerianae Jatamansi Rhizoma et Radix in the treatment of PTSD were selected according to the topological parameters. Cytoscape 3.7.2 was used to construct the compound-target network. DAVID database was used for GO enrichment analysis and KEGG enrichment analysis. The relationship network of "compound-target-pathway" was constructed through Cytoscape 3.7.2 to analyze and obtain the key targets and their corresponding components in the network, and their results were verified by molecular docking. The results showed that a total of 47 components(such as valeraldehyde, dihydrovalerin, valerate, chlorovaltrate K, 8-hydroxypinoresinol, 6-hydroxyluteolin, apigenin, farnesin, vanillin, luteolin, kaempferol, glycosmisic acid and pogostemon) of Valerianae Jatamansi Rhizoma et Radix may act on 94 key targets such as CNR1, MAOA, NR3 C1, MAPK14, MAPK8, HTR2 C and DRD2. Totally 29 GO terms were obtained by GO functional enrichment analysis(P<0.05), and 20 signaling pathways were obtained from KEGG pathway enrichment, mainly involving neuroactive ligand-receptor interaction, serotonergic synapse, calcium signaling pathway, cAMP signaling pathway, dopaminergic synapse, retrograde endocannabinoid signaling, neurotrophin signaling pathway, gap junction, cholinergic synapse, estrogen signaling pathway, glutamatergic synapse and long-term potentiation. Molecular docking analysis showed that hydrogen bonding, π-π interaction and hydrophobic effecting may be the main forms of interaction. This study used the network of compound-target-pathway and molecular docking technology to screen the effective components of Valerianae Jatamansi Rhizoma et Radix against PTSD, and explore its anti-PTSD mechanism, so as to provide scientific basis for exploring the anti-PTSD drugs from traditional Chinese medicine and clarifying its mechanism of action.

Methods:The construction process, registration content and preliminary results of HCPRRMS were systematically introduced. Results:HCPRRMS was independent developed in 2014. Since March, 2015, the system has been used to register information of patients with cerebral palsy in the Third Affiliated Hospital of Zhengzhou University. Until September, 2019, a total of 23 child rehabilitation institutions had used the registration management system. There were 1357 patients with cerebral palsy registered in this system, in which 936 cases (68.98%) were male, 501 cases (36.92%) were with gestational weeks < 37, 443 cases (32.65%) were with birth weight < 2500 g, and 430 cases (31.69%) were born with hypoxic-ischemic encephalopathy. Among them, the spastic cerebral palsy patients (1117 cases, 86.74%) accounted for the highest proportion. There was significant difference among types of cerebral palsy and the classification of GMFCS. A total of 1117 patients with cerebral palsy showed MRI-identified brain abnormalities, in which, periventricular leukomalacia accounted for the most (480 cases). For the complications, epilepsy accounted for 14.44% (196 cases), vision impairment accounted for 8.03% (109 cases), hearing impairment accounted for 11.64% (158 cases). Among 769 cases aged more than two years, language-speech dysfunction accounted for 52.66% (424 cases); and among 216 cases aged more than four years, mental retardation accounted for 37.96% (82 cases). Conclusion:HCPRRMS could help to understand the risk factors, clinical characteristics, and complications of cerebral palsy.
