Mechanism of electroacupuncture regulating the ligand pathway of tyrosine kinase receptor in improving vascular dementia / 解剖学报

Objective To observe the potential mechanism of electroacupuncture regulating the erythropoietin-producing hepatocellular receptor B2/erythropoietin-producing hepatocellular receptor-interacting B2/big mitogen-activated protein kinase 1(EphB2/EphrinB2/BMK1) signaling pathway to improve neural damage in vascular dementia rats. Methods Eighty SD male adult rats were randomly divided into a sham surgery group, a model group, a non acupoint electroacupuncture group, a nimodipine group, and an electroacupuncture three needle group. The vascular dementia rat model was made by the modified Pulsinelli four vessel occlusion method. After grouping, the rats in each group were subjected to water maze test, HE staining, Nissl staining, and transmission electron microscopy(TEM) to observe the pathological changes in the hippocampal CA1 area, and the expression of EphB2 and BMK1 in the hippocampal CA1 area was detected by immunohistochemistry; Detection of EphB2 and BMK1 protein expression in rat hippocampal CA1 region was detected by Western blotting. Results Compared with the model group, the escape latency of vascular dementia rats treated with electroacupuncture and nimodipine decreased (P0.05). Compared with the nimodipine group, the expression of EphB2 and BMK1 in the hippocampal CA1 region of rats in the electroacupuncture Zhisanzhen group significantly increased (P<0.05). Conclusion Electroacupuncture may improve the damage of hippocampal neurons in vascular dementia rats by increasing the expression of EphB2 and BMK1 in the CA1 region of the hippocampus, thereby improving the learning and memory of vascular dementia rats.

Pharmacotherapy of urethral stricture / 亚洲男科学杂志(英文版)

Urethral stricture is characterized by the chronic formation of fibrous tissue, leading to the narrowing of the urethral lumen. Despite the availability of various endoscopic treatments, the recurrence of urethral strictures remains a common challenge. Postsurgery pharmacotherapy targeting tissue fibrosis is a promising option for reducing recurrence rates. Although drugs cannot replace surgery, they can be used as adjuvant therapies to improve outcomes. In this regard, many drugs have been proposed based on the mechanisms underlying the pathophysiology of urethral stricture. Ongoing studies have obtained substantial progress in treating urethral strictures, highlighting the potential for improved drug effectiveness through appropriate clinical delivery methods. Therefore, this review summarizes the latest researches on the mechanisms related to the pathophysiology of urethral stricture and the drugs to provide a theoretical basis and new insights for the effective use and future advancements in drug therapy for urethral stricture.

OBJECTIVE@#To study the protective effect of forsythiaside B (FB) against cerebral oxidative stress injury induced by cerebral ischemia/reperfusion (I/R) in mice and explore the underlying mechanism.@*METHODS@#Ninety C57BL/6 mice were randomized into sham-operated group, middle cerebral artery occlusion (MCAO) model group, and low-, medium and highdose (10, 20, and 40 mg/kg, respectively) FB groups. The expression levels of MDA, ROS, PCO, 8-OHdG, SOD, GSTα4, CAT and GPx in the brain tissue of the mice were detected using commercial kits, and those of AMPK, P-AMPK, DAF-16, FOXO3 and P-FOXO3 were detected with Western blotting. Compound C (CC), an AMPK inhibitor, was used to verify the role of the AMPK pathway in mediating the therapeutic effect of FB. In another 36 C57BL/6 mice randomized into 4 sham-operated group, MCAO model group, FB (40 mg/kg) treatment group, FB+CC (10 mg/kg) treatment group, TTC staining was used to examine the volume of cerebral infarcts, and the levels of ROS and SOD in the brain were detected; the changes in the protein expressions of AMPK, P-AMPK, DAF-16, FOXO3 and P-FOXO3 in the brain tissue were detected using Western blotting.@*RESULTS@#In mice with cerebral IR injury, treatment with FB significantly reduced the levels of ROS, MDA, PCO and 8-OHdG, increased the activities of antioxidant enzymes SOD, GSTα4, CAT and GPx, and enhanced phosphorylation of AMPK and FOXO3 and DAF-16 protein expression in the brain tissue (P < 0.01). Compared with FB treatment alone, the combined treatment with FB and CC significantly reduced phosphorylation of AMPK and FOXO3, lowered expression of DAF-16 and SOD activity, and increased cerebral infarction volume and ROS level in the brain tissue of the mice (P < 0.01).@*CONCLUSION@#FB inhibits oxidative stress injury caused by cerebral I/R in mice possibly by enhancing AMPK phosphorylation, promoting the downstream DAF-16 protein expression and FOXO3 phosphorylation, increasing the expression of antioxidant enzymes, and reducing ROS level in the brain tissue.

Anti-pyroptosis effect of Albiziae Cortex-Tribuli Fructus combination on hepatic stellate cell line LX2: based on network pharmacology / 中国中药杂志

Based on network pharmacology, molecular docking, and in vitro experimental verification, this study aims to explore the effect of Albiziae Cortex-Tribuli Fructus combination on HSC-LX2 pyroptosis. Specifically, the targets of Albiziae Cortex, Tribuli Fructus, and hepatic fibrosis were retrieved from an online database and CNKI, and "drug-component-target" network and "drug-component-target-disease" network were constructed. Protein-protein interaction(PPI) network was established based on STRING. Metascape was employed for Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment, and the mechanism of Albiziae Cortex-Tribuli Fructus combination against liver fibrosis was predicted. Molecular docking was used to verify some of the results of network pharmacology, and in vitro experiment was carried out to further verify the above conclusions. According to the results of network pharmacological analysis, 25 active components and 439 targets of Albiziae Cortex-Tribuli Fructus combination and 152 anti-liver fibrosis targets were screened out, including nucleotide-binding oligomerization domain and leucine-rich-repeat-and pyrin-domain-containing 3(NLRP3) and caspase-1. The key targets were involved in 194 KEGG pathways in which the NOD-like receptor signaling pathway topped. The binding common targets were related to pyroptosis. The results of in vitro experiment showed that the pair-containing serum reduced the proliferation rate of HSC-LX2 and the content of reactive oxygen species(ROS), interleukin-18(IL-18), and interleukin-1β(IL-1β)(P<0.05). Western blot and qRT-PCR suggested that the protein and gene expression of NLRP3, caspase-1, α-smooth muscle actin(α-SMA), and gasdermin D(GSDMD) in HSC-LX2 increased after AngⅡ stimulation, and the expression decreased after the intervention of pair-containing serum(P<0.05). In summary, the pair-containing serum can inhibit the classic pathway of pyroptosis, which may be the anti-liver fibrosis mechanism. This is consistent with the predicted results of network pharmacology.

Brain network mechanism of Xingnao Kaiqiao acupuncture treatment for stroke / 国际中医中药杂志

Objective:To explore the effect of Xingnao Kaiqiao acupuncture treatment on brain network reorganization for the patients with stroke recovery, and therefore understand the neural mechanism underlying Xingnao Kaiqiao acupuncture treatment.Methods:Prospective case series study. Thirteen acute ischemia stroke patients were recruited from the Department of Neurology, Shanghai Minhang Hospital of Integrated Traditional Chinese and Western Medicine from Aug 2018 to Oct 2019. They were treated with Xingnao Kaiqiao acupuncture once a day for 10 consecutive days in addition to routine treatments, and received clinical assessments before treatment and 14 days after treatment onset. EEG signals were recorded during the first acupuncture treatment, from before inserting the needles (the baseline), during needle retention, to after removal of the needles. The brain network was constructed using phase locking index, and its clustering coefficient (CC), characteristic path length (PL) and small-worldness (S) were analyzed using one-way repeated ANOVA.Results:Compared with the baseline, the CC of delta-band network (sparsity=0.10: t=3.306, P=0.006; 0.12: t=2.909, P=0.013; 0.14: t=2.331, P=0.038) and the PL of delta-band (sparsity=0.12: t=3.236, P=0.007; 0.14: t=2.754, P=0.017, 0.18: t=2.878, P=0.014) and alpha-band (sparsity=0.10: t=2.432, P=0.032) networks were significantly decreased during the needle retention stage. Clinical assessments demonstrated a significant treatment efficacy of Xingnao Kaiqiao acupuncture, and its efficacy which was indicated by improved NIHSS score, was significantly correlated with the CC changes in the delta band network from baseline to needle retention. The correlation was strongest when the network sparsity was 0.12 ( r=0.78, P=0.002). Conclusion:Xingnao Kaiqiao acupuncture can regulate the brain network of stroke patients in real time, and this immediate regulation maybe associated with its treatment effect.

Chinese expert consensus on emergency surgery for severe trauma and infection prevention during corona virus disease 2019 epidemic (version 2023) / 中华创伤杂志

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Priority ranking of Chinese patent medicine prescriptions for type 2 diabetes mellitus (syndrome of deficiency of both Qi and Yin): based on analytic hierarchy process (AHP) / 中国中药杂志

Clinical expertise, patient preference, and the best evidence are the three elements of evidence-based medicine. Based on high-level and high-quality evidence, qualitative and quantitative analysis of the prescribing decisions of physicians is beneficial to improving clinical efficacy. A mature methodological system is available for the retrieval, analysis, summary, evaluation, and recommendation of the evidence, but there are still few studies on physicians' prescribing decisions. How to analyze the trend of physicians' prescribing decisions based on the priority ranking in addition and subtraction of prescriptions? Analytic hierarchy process(AHP) is a method for decision making, which arranges the elements of the decision problem into overall goal, criteria, and operational sub-criteria, and uses the matrix eigenvector method to solve the problem. This study aims to analyze the priority of physicians' prescribing decisions for diabetes mellitus with deficiency of both Qi and Yin based on AHP. To be specific, a database of diabetes mellitus cases with deficiency of both Qi and Yin was established and AHP was used to yield the priority ranking of Chinese patent medicine prescriptions in specific clinical scenarios. In the selected cases of diabetes mellitus with deficiency of both Qi and Yin, Xiaoke Pills was the best prescription for the treatment of type 2 diabetes mellitus(deficiency of both Qi and Yin)(normalized=0.388), followed by Liuwei Dihuang Pills(normalized=0.269), Qishen Capsules(normalized=0.230), and Shengmai Injection(normalized=0.113). According to the analysis the available data, for type 2 diabetes mellitus(deficiency of both Qi and Yin), Xiaoke Pills was the most effective prescription in specific scenarios. When the physicians' prescribing decisions are consistent with the evidence, quantitative analysis of physicians' cognition will boost the evidence-based medical decision-making. However, the research results are also affected by the quality of literature, evidence level and priority, which are thus have some limitations. It is recommended that further small data research based on individual cases be carried out to lay a evidence-based basis for the clinical decision-making of type 2 diabetes mellitus.

YANG Jun's clinical experience of acupuncture for oculomotor paralysis / 中国针灸

Professor YANG Jun's clinical experience of acupuncture and moxibustion for oculomotor paralysis is summarized. Professor YANG Jun pays attention to disease differentiation and syndrome differentiation in the treatment of this disease. According to the characteristics of oculomotor paralysis, "early diagnosis and seeking treatment from the source" is advocated. According to the etiology and pathogenesis, professor YANG divides oculomotor paralysis into three types: the syndrome of wind-evil attacking collaterals, the syndrome of spleen-stomach weakness and the syndrome of qi-deficiency and blood-stasis. As such, the acupoints are selected according to syndrome differentiation, and several different acupuncture methods (pricking needling at eyelids, penetrating needling and lifting eyelids and contralateral- balance needling on the healthy side) are adopted to improve the symptoms of oculomotor paralysis. It is also suggested to use the combination of scalp acupuncture and electroacupuncture to achieve the best dose-effect state. Moreover, local stimulation around the eyes is important to achieve the effects of "qi reaching affected area".

A nomogram for predicting lymph node metastasis in early gastric cancer / 中华胃肠外科杂志

Objective: To explore the independent risk factors of lymph node metastasis (LNM) in early gastric cancer, and to use nomogram to construct a prediction model for above LNM. Methods: A retrospective cohort study was conducted. Inclusion criteria: (1) primary early gastric cancer as stage pT1 confirmed by postoperative pathology; (2) complete clinicopathological data. Exclusion criteria: (1) patients with advanced gastric cancer, stump gastric cancer or history of gastrectomy; (2) early gastric cancer patients confirmed by pathology after neoadjuvant chemotherapy; (3) other types of gastric tumors, such as lymphoma, neuroendocrine tumor, stromal tumor, etc.; (4) primary tumors of other organs with gastric metastasis. According to the above criteria, 1633 patients with early gastric cancer who underwent radical gastrectomy at the Department of General Surgery of the Chinese PLA General Hospital First Medical Center from December 2005 to December 2020 were enrolled as training set, meanwhile 239 patients with early gastric cancer who underwent gastrectomy at the Department of General Surgery of the Chinese PLA General Hospital Fourth Medical Center from December 2015 to December 2020 were enrolled as external validation set. Risk factors of LNM in early gastric cancer were identified by using univariate and multivariate logistic regression analyses. A nomogram prediction model was established with significant factors screened by multivariate analysis. Area under the receiver operating characteristic curve (AUC) was used for assessing the predictive value of the model. Calibration curve was drawn for external validation. Results: Among 1633 patients in training set, the mean number of retrieved lymph nodes was 20 (13-28), and 209 patients (12.8%) had lymph node metastasis. Univariate analysis showed that gender, resection range, tumor location, tumor morphology, lymph node clearance, vascular invasion, lymphatic cancer thrombus, tumor length, tumor differentiation, microscopic presence of signet ring cells and depth of tumor invasion were associated with LNM (all P<0.05). Multivariate analysis revealed that females, tumor morphology as ulcer type, vascular invasion, lymphatic cancer thrombus, tumor length≥3 cm, deeper invasion of mucosa, and poor differentiation were independent risk factors for LNM in early gastric cancers (all P<0.05). Receiver operating characteristic curve indicated that AUC of training set was 0.818 (95%CI: 0.790-0.847) and AUC of external validation set was 0.765 (95%CI: 0.688-0.843). The calibration curve showed that the LNM probability predicted by nomogram was consistent with the actual situation (C-index: 0.818 in training set and 0.765 in external validation set). Conclusions: Females, tumor morphology as ulcer type, vascular invasion, lymphatic cancer thrombus, tumor length≥3 cm, deeper invasion of mucosa and poor differentiation are independent risk factors for LNM of early gastric cancer. The establishment of a nomogram prediction model for LNM in early gastric cancer has great diagnostic value and can provide reference for treatment selection.

Clinical and laboratory diagnosis of indolent leukemic mantle cell lymphoma: report of one case and review of literature / 白血病·淋巴瘤

Objective:To improve the understanding of indolent mantle cell lymphoma (MCL).Methods:The data of a patient with indolent leukemic MCL in the Second Affiliated Hospital of Nanjing Medical University in May 2013 were collected. The cell morphology was analyzed by using cell smear, the flow cytometry was used to make immunophenotype analysis, the karyotype analysis was performed by usig cytogenetic technique, and polymerase chain reaction (PCR) was used to make the immunoglobulin gene analysis. At the same time, lymph node pathology and immunohistochemistry were also analyzed. The related articles published were reviewed to sum up the characteristics and the treatment of indolent MCL.Results:The male patient aged 60 years was obviously asymptomatic accompanied with slow disease progression, leukemic manifestation and without lymphadenopathy. He received pathological biopsy because of located lymphadenopathy in 2008. Small cell morphology, Kappa light chain immunophenotype, t(11;14) translocation showed after the cytogenetic examination, clonal immune globulin gene rearrangement and low Ki-67 positive index were identified. In situ MCL was diagnosed by retrospective pathology.Conclusions:Indolent MCL is extremely rare. It is typically asymptomatic with none or minimal nodal involvement, indolent disease course, leukemic phase with mild lymphocytosis, Kappa light chain expression, simple karyotype, classical or small cell morphology of tumor cells and the positive index of Ki-67 <10%. In situ MCL can be seen in pathology examination. IgVH gene mutation positive and SOX11 negative expression are notable in indolent MCL. International prognostic index of MCL is probably not appropriate in the prognostic analysis of leukemic indolent MCL. It is emphasized that initial observation and having therapies only after the disease progression can be suited for indolent MCL.

Burden of disease and risk factors among children under 5 years in China from 1990 to 2019: a perspective of international comparison / 中华预防医学杂志

Based on the Global Burden of Disease study 2019, the standardized mortality rate and disability-adjusted life years (DALYs) rate of children under 5 years old were selected as evaluation indicators to compare and analyze the current situation and differences of disease burden of children under 5 years old between China and other regions from 1990 to 2019. The change trend and difference of disease burden of children under 5 years old in China were analyzed by sexes. From 1990 to 2019, the all-cause standardized mortality rate of children under 5 years old in China decreased from 1 153.81/100 000 to 160.39/100 000, and the all-cause standardized DALY rate decreased from 104 426.40/100 000 to 16 479.01/100 000. In 2019, neonatal preterm birth, congenital heart anomalies and lower respiratory infections ranked the top three disease burden of children under 5 years old in China. Except that the disease burden of neonatal preterm birth was lower than that in North America, they were much higher than that in Western Europe and North America in the same period. The burden of unintentional injury diseases, including pulmonary aspiration and foreign body in airway and drowning, was higher than that in Western Europe and North America. The standardized mortality and DALY rate of the top ten diseases and injuries in boys and girls under 5 years old in China showed a downward trend (P<0.05), and most of them were higher in boys than girls (P<0.05). From 1990 to 2019, the disease burden of children under 5 years old in China decreased significantly. However, compared other regions, it is still necessary to strengthen the prevention and control of neonatal premature birth, birth defects and unintentional injuries, and take different sex-specific interventions to improve the overall health of children.

Investigation of cerebrospinal fluid metabolites in patients with leptomeningeal metastases from lung adenocarcinoma based on untargeted metabolomics / 国际肿瘤学杂志

Objective:To analyze the diagnostic value of metabolic makers in cerebrospinal fluid in advanced lung adenocarcinoma patients with leptomeningeal metastases (LM) .Methods:A total of 46 cerebrospinal fluid samples (LM group) from lung adenocarcinoma patients with LM admitted to Nanjing Drum Tower Hospital Affiliated to Nanjing University Medical School from December 2019 to December 2021 were collected, and 48 cerebrospinal fluid samples (control group) from patients with benign neurological diseases during the same period were collected. Metabolomics analysis of cerebrospinal fluid was carried out by high-performance liquid chromatography-mass spectrometry. Principle component analysis (PCA) and orthogonal to partial least squares discriminant analysis (OPLS-DA) were used for modeling. Multi-criteria assessment was used to identify the different metabolites between the two groups. Receiver operating characteristic (ROC) curve, pathway enrichment analysis and other methods were used to screen metabolites and pathways related to LM from lung adenocarcinoma.Results:There were no statistically significant differences in the proportions of age ( Z=-0.41, P=0.210) , gender ( χ2=1.19, P=0.275) , history of smoking ( χ2=2.86, P=0.091) , Karnofsky performance status score ( χ2=0.65, P=0.419) and increased intracranial pressure ( χ2=0.65, P=0.419) between the LM group and control group. The models of PCA (R2X was 0.608 and 0.583, Q2 was 0.462 and 0.513 in electrospray ion positive and negative modes, respectively) and OPLS-DA (R2Y was 0.967 and 0.889, Q2 was 0.959 and 0.852 in electrospray ion positive and negative modes, respectively) showed that the overall data quality was good. Meanwhile, the model interpretation rate and prediction rate were effective. The permutation tests duplicated for 200 times and showed no over-fitting of the established model. The metabolic profiles of the two groups were significantly different. A total of 30 endogenously differential metabolites were screened by using multi-criteria assessment. Six potential biomarkers with larger area under the curve (AUC) were identified through ROC curve analysis, including tyrosine (AUC=0.967, 95% CI: 0.906-1.000) , phenylalanine (AUC=0.992, 95% CI: 0.973-1.000) , pyruvate (AUC=0.976, 95% CI: 0.935-1.000) , tryptophan (AUC=0.935, 95% CI: 0.880-0.973) , glucose (AUC=0.932, 95% CI: 0.880-0.975) and adenosine monophosphate (AUC=0.993, 95% CI: 0.987-1.000) . The 30 selected differential metabolites were enriched and analyzed for metabolic pathways, and 20 relevant metabolic pathways were matched. Among them, the four metabolic pathways most likely to cause changes in metabolites were glycolysis and glucose metabolic synthesis, pyruvate metabolism, phenylalanine metabolism, phenylalanine, tyrosine and tryptophan biosynthesis. Conclusion:Untargeted metabolomics analysis can effectively screen specific cerebrospinal fluid metabolites in lung adenocarcinoma patients with LM. Six potential metabolites such as tyrosine, phenylalanine, pyruvate, tryptophan, adenosine monophosphate, glucose and their metabolic pathways may be involved in the pathogenesis of LM from lung adenocarcinoma.

Repairing Diabetic Wounds with Polysaccharides from Traditional Chinese Medicines： A Review / 中国实验方剂学杂志

As of 2020， there are more than 120 million diabetic patients in China. Diabetic wounds is one of the common complications of diabetes with increasing incidence and has the potential to cause disability and mortality. Traditional Chinese medicine （TCM） has a long history in treating diabetic wounds， demonstrating significant efficacy and safety. In recent years， increasing researchers have explored the mechanisms of polysaccharides from TCM in the repair of diabetic wounds. Polysaccharides are the main active ingredients of TCM and employ one or more blood sugar-lowering mechanisms. However， most studies focus on the repair mechanism of single polysaccharides， and there is little in-depth discussion and summary. To provide a new therapy for diabetic wounds， which meets international standards and has the characteristics of TCM， and provide reference for the clinical treatment of diabetic wounds， we reviewed relevant literature to summarize the mechanisms of TCM polysaccharides in treating diabetic wounds. The mechanisms include inhibiting inflammation to improve wound microenvironment， lowering blood sugar， promoting fibroblast migration and proliferation， regulating wound growth factor to promote angiogenesis， inhibiting oxidative stress response， and regulating immune function. Finally， we put forward some possible research directions in the future.

Objective:To analyze the clinical application and to evaluate the efficiency of hysteroscopical electroresection of International Federation of Gynecology and Obstetrics (FIGO) type 3 myoma.Methods:The clinical data of patients who underwent hysteroscopical electroresection single FIGO type 3 myoma in Obstetrics and Gynecology Hospital of Fudan University from January 2019 to October 2021 were collected retrospectively. The clinical symptoms, myoma size, location, operation time, intraoperative bleeding, surgical complications and postoperative follow-up were recorded, and the subsequent pregnancy outcomes were followed-up.Results:Totally 35 patients with FIGO type 3 myoma were included in this study. The average age was (36.6±4.7) years old, the diameter of myoma was (4.0±1.2) cm (range: 2.0-5.8 cm). The rate of complete resection of myoma in one operation was 86% (30/35), the average operation time was (41±15) minutes (range: 20-65 minutes), and the average intraoperative bleeding was (24±18) ml (range: 5-150 ml). No complications such as uterine perforation, massive hemorrhage, hyperhyderation syndrome and infection occurred in all patients perioperation. There were 20 cases with significant increase of menstruation before operation, the cure rate and effective rate of hysteroscopical electroresection of FIGO type 3 myoma were 75% (15/20) and 95% (19/20). There were 24 patients with fertility requirements, their average follow-up time was (14.5±6.8) months, the pregnancy rate within 1 year after operation was 79% (19/24), and the average postoperative pregnancy time was (5.8±3.4) months. There were 15 cases who had completed delivery after operation, including 10 cases of vaginal delivery and 5 cases of cesarean section, and none of them had uterine rupture.Conclusions:Hysteroscopy could effectively resect FIGO type 3 myoma. Hysteroscopical electroresection of FIGO type 3 myoma is minimally invasive with rapid postoperative recovery and could achieve pregnancy in a short time, which is not only helpful to reduce the amount of menstruation, but also beneficial for the prognosis of fertility. It should be carried out by the experienced hysteroscopists.

Objective To observe the effect of acupoint catgut embedding on the expression of inflammatory factor mRNA in cyclooxygenase-2 (COX-2)/prostaglandin E2 (PGE2) signal pathway of vascular dementia (VD) rats, and to explore the protective mechanism of acupoint catgut embedding on the brain inflammatory response of VD rats. Methods VD model was established by the modified Pulsinelli ' s four vessel blocking method. Totally 148 male rats were randomly divided into VD model group, non acupoint catgut embedding group and acupoint catgut embedding group. On the 7th day after operation, catgut embedding at acupoints and catgut embedding at non acupoints were performed in the two treatment groups respectively, and materials were taken out 15 days later. Western blotting was used to detect the expression of COX-2 and PGE2, and real-time PCR was used to detect the mRNA expression of tumor necrosis factor α (TNF-α), intercellular cell adhesion molecule 1 (ICAM-1), interieukin(IL)-6, macrophage inflammatory protein 2 (MIP-2), IL-lβ, and monocyte chemotactic protein 1 ( MCP-1 ) in rat hippocampus. Results Compared with the sham group, the expressions of COX-2, PGE2, TNF-α, ICAM-1, IL-6, MIP-2, IL-lβ and MCP-1 in hippocampus of the other three groups were significantly higher (P<0.01). Compared with the model group, the expressions of COX-2, PGE2 protein and TNF-α, ICAM-1, IL-6, MIP-2, IL-lβ, MCP-1 mRNA in the hippocampus of the acupoint catgut embedding group and the non acupoint catgut embedding group decreased significantly (P<0.01). Conclusion Acupoint catgut embedding can protect the brain from inflammatory injury by down-regulating the expression of related inflammatory factors in COX-2/PGE2 signaling pathway and reducing the inflammatory response induced by VD rats.

Research progress of T-type calcium channel in cancer / 中国医师杂志

In most non-excited cells, voltage-gated T-type calcium channels present three properties of activation, inactivation and slow inactivation, thus contribute to cellular calcium signaling and membrane potential. By which T-type calcium channels play an important role in many cancer cellular processes such as cell proliferation, differentiation, apoptosis, invasion, and metastasis. Inhibiting T-type calcium channels by drugs or genetic tools can change the related cellular currents and the intracellular Ca 2+ , thereby regulating the biological tumorigenesis. This article reviews the electrophysiological of T-type calcium channels during tumor progression, aims to provide a scientific basis for the study and treatment in cancer.
