Effect of traditional Chinese medicine on portal vein thrombosis in patients with liver cirrhosis and its medication characteristics / 临床肝胆病杂志

Objective To investigate the therapeutic effect of traditional Chinese medicine (TCM) on portal vein thrombosis (PVT) in patients with liver cirrhosis and its medication characteristics. Methods A retrospective analysis was performed for 89 patients with liver cirrhosis and PVT who were hospitalized and treated in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, and according to whether TCM treatment was applied in combination, they were divided into TCM group with 59 patients and control group with 30 patients. Related data were collected for the two groups, including demographic data, laboratory examination, radiological examination, gastroscopy, history of surgery, portal hypertension-related complications, medication, and follow-up data. The independent samples t -test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups. An ordinal polytomous Logistic regression analysis was used for multivariate analysis. TCM Inheritance Computing Platform (V3.0) was used to perform a drug effect cluster analysis of TCM prescriptions. Results The multivariate logistic regression analysis showed that esophageal and gastric varices (odds ratio [ OR ]=3.144, 95% confidence interval [ CI ]: 1.221-8.094), PVT involving the portal vein (PV) and the superior mesenteric vein (SMV) ( OR =51.667, 95% CI : 3.536-754.859), PVT involving PV+spleen vein (SV)+SMV ( OR =13.271, 95% CI : 2.290-76.928), cavernous transformation of the portal vein ( OR =11.896, 95% CI : 1.172-120.696), and TCM intervention ( OR =0.348, 95% CI : 0.129-0.938) were influencing factors for the outcome of PVT in liver cirrhosis. Follow-up results showed that compared with the control group, the TCM group had a significantly lower progression rate (16.95% vs 56.67%, P < 0.001) and a significantly lower incidence rate of variceal rupture and bleeding (8.47% vs 33.33%, P < 0.001). Effective TCM drugs with a relatively high frequency of use included deficiency-tonifying drugs (359 times, 34.6%), blood-activating and stasis-resolving drugs (202 times, 19.5%), and diuresis-inducing and dampness-draining drugs (180 times, 17.3%); the TCM drugs with a relatively high frequency of use included Astragalus membranaceus (57 times, 8.7%), Angelica sinensis (50 times, 7.6%), and leech (48 times, 7.3%); TCM drug combinations with a relatively high frequency of use included Astragalus membranaceus+Angelica sinensis, Astragalus membranaceus+leech, Angelica sinensis+leech, and Astragalus membranaceus+Angelica sinensis+leech. Conclusion Qi-tonifying, blood-activating, and stasis-breaking drugs, such as Astragalus membranaceus, Angelica sinensis, and leech, can promote the stabilization or recanalization of PVT in liver cirrhosis and reduce the incidence rate of bleeding events due to portal hypertension.

Neuroprotective Effects of the Psychoactive Compound Biatractylolide (BD) in Alzheimer's Disease.

Mitochondria play a central role in the survival or death of neuronal cells, and they are regulators of energy metabolism and cell death pathways. Many studies support the role of mitochondrial dysfunction and oxidative damage in the pathogenesis of Alzheimer's disease. Biatractylolide (BD) is a kind of internal symmetry double sesquiterpene novel ester compound isolated from the Chinese medicinal plant Baizhu, has neuroprotective effects in Alzheimer's disease. We developed a systematic pharmacological model based on chemical pharmacokinetic and pharmacological data to identify potential compounds and targets of Baizhu. The neuroprotective effects of BD in PC12 (rat adrenal pheochromocytoma cells) and SH-SY5Y (human bone marrow neuroblastoma cells) were evaluated by in vitro experiments. Based on the predicted results, we selected 18 active compounds, which were associated with 20 potential targets and 22 signaling pathways. Compound-target, target-disease and target-pathway networks were constructed using Cytoscape 3.2.1. And verified by in vitro experiments that BD could inhibit Aß by reducing oxidative stress and decreasing CytC release induced mPTP opening. This study provides a theoretical basis for the development of BD as an anti-Alzheimer's disease drug.

The development and validation of a predictive model for neonatal phototherapy outcome using admission indicators.

Delayed exchange transfusion therapy (ETT) after phototherapy failure for newborns with severe hyperbilirubinemia could lead to serious complications such as bilirubin encephalopathy (BE). In this current manuscript we developed and validated a model using admission data for early prediction of phototherapy failure. We retrospectively examined the medical records of 292 newborns with severe hyperbilirubinemia as the training cohort and another 52 neonates as the validation cohort. Logistic regression modeling was employed to create a predictive model with seven significant admission indicators, i.e., age, past medical history, presence of hemolysis, hemoglobin, neutrophil proportion, albumin (ALB), and total serum bilirubin (TSB). To validate the model, two other models with conventional indicators were created, one incorporating the admission indicators and phototherapy failure outcome and the other using TSB decrease after phototherapy failure as a variable and phototherapy outcome as an outcome indicator. The area under the curve (AUC) of the predictive model was 0.958 [95% confidence interval (CI): 0.924-0.993] and 0.961 (95% CI: 0.914-1.000) in the training and validation cohorts, respectively. Compared with the conventional models, the new model had better predictive power and greater value for clinical decision-making by providing a possibly earlier and more accurate prediction of phototherapy failure. More rapid clinical decision-making and interventions may potentially minimize occurrence of serious complications of severe neonatal hyperbilirubinemia.

Determinants of Infant Young Child Feeding Among Mothers of Malnourished Children in South Punjab, Pakistan: A Qualitative Study.

Inadequate feeding is one of the most critical underlying determinants of child malnutrition. In this study, we explore infant young child feeding (IYCF) and deconstruct breastfeeding barriers in mothers of severely malnourished children in one of the most marginalized districts of Punjab province of Pakistan. Using purposive sampling, 20 lactating mothers are recruited for open-ended semi-structured interviews. Results reveal that barriers to immediate and exclusive breastfeeding include the introduction of pre-lacteal, butter, and cow or formula milk by mothers and grandmothers. Birthing difficulties and ritualizing prelacteal to transfer religion and culture cause the delay of early initiation of breastmilk. The colostrum is also discarded based on its weird physical look. Moreover, household circumstances, limited diet, extra workload, and mental stress associated with marital relationships are other significant barriers. Mothers perceive their breastmilk as thin, impotent, and of bad quality and often complain against breastmilk insufficiency due to general weakness. Furthermore, poor mothers reduce breastfeeding when the fertility burden is high, especially if a female baby is in their womb. Alternatively, outer milk is recommended but washing bottles with detergents often becomes frequent. In conclusion, immediacy, exclusivity, frequency, and duration of breastfeeding are circumscribed owing to multiple social, cultural, and economic causes. Therefore, a holistic approach combining cultural and structural causes might be more relevant for successful IYCF practices in marginalized communities of Pakistan.

Curcumin alleviated lipopolysaccharide-induced lung injury via regulating the Nrf2-ARE and NF-κB signaling pathways in ducks.

BACKGROUND: Under the intensive modern poultry farming system, the lung of duck is one of the main target organs for various bacterial and viral infections. Curcumin is a kind of natural polyphenol compound for which various beneficial biological functions exist, including being an anti-inflammatory, antioxidant, and antiviral. The aim of this work was to investigate the mechanism of curcumin-alleviated lipopolysaccharide (LPS)-induced lung damage by the nuclear erythroid 2-related factor 2 (Nrf2)-antioxidant reaction element (ARE) and nuclear factor kappa B (NF-κB) signaling pathway in ducks. RESULTS: In total, 450 one-day-old male specific pathogen-free ducks were randomly assigned into three dietary treatments: CON, basal diet; LPS, basal diet + LPS treatment; LPS + CUR, basal diet + LPS + 500 mg kg-1 of curcumin. At the end of the experiment (21 days), ducks in LPS treatment were challenged with 5 mg LPS per kilogram of body weight and the other two treatments were injected with the same dose of phosphate-buffered saline solution. The results showed that LPS caused acute inflammation, oxidation stress, and lung injury. Dietary addition of curcumin significantly relieved the oxidation stress and inflammation parameters. Moreover, the results showed that remission may be through the signaling pathways of both Nrf2-ARE and NF-κB. CONCLUSION: In conclusion, dietary supplementation of 500 mg kg-1 of curcumin exhibited a lung-protective effect in ducks. This experiment broadens the mode of metabolism actions of curcumin in the target organs and provides an insight for the application of curcumin in waterfowl feed. © 2022 Society of Chemical Industry.

A randomized sham-controlled trial of manual acupuncture for infertile women with polycystic ovary syndrome.

BACKGROUND: Polycystic ovary syndrome (PCOS) is a complex polygenic disease and is one of the most common endocrinological and reproductive disorders. The purpose of this study was to evaluate the efficacy of acupuncture combined with herbal medicine among infertile females with polycystic ovary syndrome (PCOS). METHOD: A total of 86 women with PCOS, experiencing infertility, were recruited and randomly assigned to receive either manual acupuncture (MA) or sham acupuncture (SA) twice per week for three menstrual cycles. Both groups received herbal medication. The evaluations were conducted after three menstrual cycles and 24 weeks' follow-up. RESULTS: The trial was completed by 79 (91.86%) of the 86 randomly selected patients. During this study, the pregnancy rate in the MA group (46.34%) was significantly higher than the SA group (18.42%), with a P-value of 0.008. Moreover, the ovulation rate of the MA group (58.14%) was higher than that of the SA group (45.74%), with a P-value of 0.046. The improvement rate of PCOS score and testosterone level showed a statistical difference between the two groups (P-values were <0.05). There were no other differences between the two groups. Sex hormones level, including E2, T, P, LH, and LH/FSH were significantly lower after intervention in the MA group (P-values were <0.05) compared with baseline, while only the progesterone level was reduced in the SA group (P-value = 0.008). CONCLUSION: Manual acupuncture combined with herbal medicine may be clinically useful for infertile women with PCOS in improving pregnancy and ovulation rate.

Enhanced luminescence performances of BaLaMgTaO6:Mn4+ red phosphor by Bi3+, Ca2+ doping for indoor plant lighting supplementary LED.

A new perovskite BaLaMgTaO6:Mn4+ (BLMTO:Mn4+) red phosphor was synthesized for the first time via the high-temperature solid-state method. The emission band of the phosphor ranges from 650 to 750 nm, which matches well with the absorption band of PFR and PR. By doping of Bi3+ and Ca2+ ions in the BLMTO:Mn4+ phosphor, a 4.76-fold enhancement in the luminescence emission intensity was achieved. The optimized BLMTO:0.5%Mn4+, 1.5%Bi3+, 2%Ca2+ phosphor exhibited a high quantum efficiency of 65% and a high color purity of 98.1% with the chromaticity coordinate (CIE) at (0.733, 0.267). Finally, a LED device was fabricated with the BLMTO:0.5%Mn4+, 1.5%Bi3+, 2%Ca2+ phosphor for further agricultural lighting, which emits warm white light with a low color temperature of 3549 K. The result indicates that the BLMTO:Mn4+, Bi3+, Ca2+ phosphors have a potential for applications in agricultural cultivations.

Clinical metabolomics research on Xiaozhang Tie with the umbilical compress therapy for cirrhotic ascites / 药学学报

We used metabolomics technology to identify and understand the biomarkers and therapeutic mechanisms of umbilical compress therapy based on Xiaozhang Tie (XT) to provide scientific evidence for its clinical application. A total of 10 patients with cirrhotic ascites and gastrointestinal motility disorders who were hospitalized in the Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from November 2017 to June 2018 were divided into a placebo group (4 cases) or an XT group (5 cases), and 10 healthy volunteers were included as controls. This clinical trial was approved according to the Ethics Committee of Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine (2017-528-11-01). The patients in the XT group were given umbilical compress therapy with Xiaozhang Tie, and patients in the placebo group were administered a plaster patch in which the drug content was less than 5%, receiving one patch per day for three consecutive days. Non-targeted metabolomics technology and UPLC-Q/Orbitrap-MS/MS analysis technology were utilized to investigate the fluctuations in endogenous metabolic profiles in the patient's urine prior to and after administration of XT. By analyzing and comparing the urine metabolic profiles of patients with cirrhotic ascites to those of healthy volunteers, a total of 31 biomarkers were identified, 14 of which were significantly decreased by the intervention with Xiaozhang Tie (P <0.05). Pathway enrichment analysis revealed that phenylalanine metabolism and tryptophan metabolism are key pathways affected by XT treatment. The results suggest that XT can alleviate cirrhotic ascites by modulating abnormalities in amino acid metabolism.

Curcumol inhibits the proliferation and metastasis of melanoma via the miR-152-3p/PI3K/AKT and ERK/NF-κB signaling pathways.

Melanoma is the most aggressive and treatment-resistant form of skin cancer. Curcumol is a Chinese medicinal herb traditionally used as a cancer remedy. However, the molecular mechanisms underlying the anticancer activity of curcumol in melanoma remains largely unknown. In the present study, we observed that Curcumol decreased mouse melanoma B16 cell proliferation and migration. The xenograft tumor assay showed that curcumol reduced melanoma volume and lung metastasis. Curcumol upregulated the expression of E-cadherin and downregulated the expression of N-cadherin, MMP2 and MMP9 in mouse melanoma B16 cell. Western blot analysis revealed that curcumol reduced the translocation of p65 to the nucleus and decreased p-ERK. Furthermore, curcumol attenuated c-MET, P13K and p-AKT protein expression and upregulated miR-152-3p gene expression. The dual-luciferase reporter assay indicated that c-MET was a target gene of miR-152-3p. Reduced expression of miR-152-3p partially attenuated the effect of curcumol on mouse melanoma B16 cell proliferation and migration. The decrease in c-MET, P13K and p-AKT protein expression following curcumol treatment in mouse melanoma B16 cells was notably attenuated by the miR-152-3p inhibitor. Taken together, our findings suggested that curcumol attenuated melanoma progression and concomitantly suppressed ERK/NF-κB signaling and promoted miR-152-3p expression to inactivate the c-MET/PI3K/AKT signaling pathway.

Advances in drug therapy for primary biliary cholangitis / 临床肝胆病杂志

Primary biliary cholangitis (PBC) is a cholestatic liver disease with unclear etiology and pathogenesis. Ursodeoxycholic acid and obeticholic acid are the therapeutic drugs for PBC approved by the US Food and Drug Administration, both of which have the effect of alleviating intrahepatic cholestasis. However, some patients still have poor biochemical response to them, and it is urgent to explore new therapeutic drugs or methods. Fibrates, immunosuppressants, and traditional Chinese medicine have a certain effect in the treatment of patients with PBC, but further studies are needed to analyze their clinical safety and mechanism of action.

WBQ5187, a Multitarget Directed Agent, Ameliorates Cognitive Impairment in a Transgenic Mouse Model of Alzheimer's Disease and Modulates Cerebral ß-Amyloid, Gliosis, cAMP Levels, and Neurodegeneration.

Previously, we designed, synthesized, and evaluated a series of quinolone-benzofuran derivatives as multitargeted anti-Alzheimer's disease (anti-AD) compounds, and we discovered that WBQ5187 possesses superior anti-AD bioactivity. In this work, we investigated the pharmacokinetics of this new molecule, as well as its therapeutic efficacy in restoring cognition and neuropathology, in the APP/PS1 mouse model of AD. Pharmacokinetic analyses demonstrated that WBQ5187 possessed rational oral bioavailability, metabolic stability, and excellent blood-brain barrier (BBB) permeability. Pharmacodynamics studies indicated that a 12-week treatment with the lead compound at doses of 40 mg/kg or higher significantly enhanced the learning and memory performance of the APP/PS1 transgenic mice, and the effect was more potent than that of clioquinol (CQ). Furthermore, WBQ5187 notably reduced cerebral ß-amyloid pathology, gliosis, and neuronal cell loss and increased the levels of cAMP in the hippocampus of these mice. The surrogate measures of emesis indicated that WBQ5187 had no effect at its cognitive effective doses. Overall, our results demonstrated that this compound markedly improves cognitive and spatial memory functions in AD mice and represents a promising pharmaceutical agent with potential for the treatment of AD.

Observation of the therapeutic and characteristic effects of terlipressin on refractory cirrhotic ascites / 中华肝脏病杂志

Objective@#To observe the therapeutic effect of terlipressin on refractory ascites (RA) in cirrhosis, and its role and impact on acute kidney injury (AKI).@*Methods@#A non-randomized controlled clinical trial data of 111 hospitalized cases of liver cirrhosis accompanied with RA was collected from Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Zhongshan Hospital of Hubei Province, The First Affiliated Hospital of Zhengzhou University, The First Affiliated Hospital of Medical School of Zhejiang University, and People's Hospital of Pudong New Area of Shanghai between March 2015 and March 2017. 26 cases of conventional treatment group (control group) were divided into two subgroups: RA without AKI (RA-NAKI) and RA with AKI (RA-AKI), and each subgroup consisted 13 cases. Patients with bacterial infection were treated with diuretics, albumin supplementation and antibiotics. 85 cases were presented in terlipressin combined treatment group, of which 27 cases were of RA-NAKI and 58 cases were of RA-AKI. Control group was injected terlipressin 1mg of intravenous drip or static push (once q6 h ~ 12 h) for more than 5 days. The treatment duration lasted for 2 weeks with 4 weeks of follow-up. Body weight, 24-hour urine volume, abdominal circumference, mean arterial pressure (MAP), liver and kidney function, anterior hepatic ascites, deepest point of ascites, and ultrasonographic detection of ascites in supine position before treatment, one and two weeks after treatment and 4 weeks after follow-up were compared. Count data were tested by χ 2. Samples of four groups at baseline were compared. One-way analysis of variance was used for normal distribution data and Kruskal-Wallis H test for non-normal distribution data. Repeated measures analysis of variance was used to compare the difference in efficacy between different time points before and after treatment in the group. The LSD method of one-way ANOVA was used to compare the two groups. A t-test of independent samples was used to compare the efficacy of different time series between the two groups. Mann-Whitney rank- sum test was used to compare the data of non-normal distribution between the two groups.@*Results@#(1) Baseline data were compared among 4 subgroups of terlipressin RA-NAKI and control RA-AKI. Control group age was higher than that of terlipressin group, and the serum creatinine (SCr) of the RA-AKI group was higher than RA-NAKI group, and there was no significant difference in the rest of the baseline data and the combined medication (P > 0.05). (2) An intra-group comparison between control and trelipressin before and after treatment showed that all patients had lower body mass, abdominal circumference and deepest ascites, and higher serum albumin (P < 0.05). 24-hour urine volume and MAP was significantly increased in the terlipressin group, while the pre-ascites, SCr and child Turcotte Pugh (CTP) scores were decreased. Body weight, abdominal circumference, pre-ascites, and deepest ascites of the terlipressin group were decreased, while MAP was increased during the treatment and follow-up periods. The differences were statistically significant when compared with the control group at the same time (P < 0.05). There was a statistically significant difference in the increase of 24-h urine volume in the terlipressin group compared with the control group (P < 0.05). The decrease in SCr and CTP in the terlipressin group after 2 weeks of treatment and 4 weeks of follow-up was statistically significant compared with the control group (P < 0.05). (3) Among the two subgroups of RA-AKI and RA-NAKI in the terlipressin group, the baseline SCr value of the former was higher than that of the latter. After treatment, the body weight, abdominal circumference, pre-ascites, deepest ascites and CTP scores were decreased. In the RA-AKI group, 24-hour urine volume, MAP, SCr and serum albumin concentration were significantly increased. The difference between the two subgroups before and after treatment was compared, and the body weight of RA-AKI group at 1, 2 weeks of treatment and 4 weeks of follow-up was significantly lower than RA-NAKI group, which were (- 2.3 ± 0.2 vs. - 1.5 ± 0.2) kg, (- 4.1 ± 0.2 vs. - 2.6 ± 0.2) kg, (- 4.2 ± 0.3 vs. - 2.4 ± 0.3) kg, respectively. RA-NAKI group urine volume was significantly increased at 2 weeks of treatment and 4 weeks of follow-up, which was (468 ± 42 vs. 110 ± 131) ml, (272 ± 34 ml vs. 11 ± 112) ml, respectively. SCr reduction (18.3 ± 4.7 vs. 0.9 ± 2.4) µmol/l at 4 weeks of follow-up was apparent in RA-NAKI group, and the difference was statistically significant (P < 0.05).@*Conclusion@#Addition of terlipressin to conventional treatment may significantly increase MAP, 24-h urine volume, improve renal function and promote ascites resolution in patients with refractory cirrhotic ascites. Moreover, its combination effect is more obvious in AKI patients, and adverse reactions are mild.

Metabolite profiling and genome-wide association studies reveal response mechanisms of phosphorus deficiency in maize seedling.

Inorganic phosphorus (Pi) is an essential element in numerous metabolic reactions and signaling pathways, but the molecular details of these pathways remain largely unknown. In this study, metabolite profiles of maize (Zea mays L.) leaves and roots were compared between six low-Pi-sensitive lines and six low-Pi-tolerant lines under Pi-sufficient and Pi-deficient conditions to identify pathways and genes associated with the low-Pi stress response. Results showed that under Pi deprivation the concentrations of nucleic acids, organic acids and sugars were increased, but that the concentrations of phosphorylated metabolites, certain amino acids, lipid metabolites and nitrogenous compounds were decreased. The levels of secondary metabolites involved in plant immune reactions, including benzoxazinoids and flavonoids, were significantly different in plants grown under Pi-deficient conditions. Among them, the 11 most stable metabolites showed significant differences under low- and normal-Pi conditions based on the coefficient of variation (CV). Isoleucine and alanine were the most stable metabolites for the identification of Pi-sensitive and Pi-resistant maize inbred lines. With the significant correlation between morphological traits and metabolites, five low-Pi-responding consensus genes associated with morphological traits and simultaneously involved in metabolic pathways were mined by combining metabolites profiles and genome-wide association study (GWAS). The consensus genes induced by Pi deficiency in maize seedlings were also validated by reverse-transcription quantitative polymerase chain reaction (RT-qPCR). Moreover, these genes were further validated in a recombinant inbred line (RIL) population, in which the glucose-6-phosphate-1-epimerase encoding gene mediated yield and correlated traits to phosphorus availability. Together, our results provide a framework for understanding the metabolic processes underlying Pi-deficient responses and give multiple insights into improving the efficiency of Pi use in maize.

[Exploring research ideas of mechanism of dominant diseases in traditional Chinese medicine based on evidence-based medicine].

The prescription of clinical curative effect has promoted the formation and development of the dominant diseases in traditional Chinese medicine, but it has been controversial for a long time because its mechanism has not been effectively explained. Breaking the gap between animal/cell research and clinical research, and understanding the mechanism of dominant diseases in traditional Chinese medicine based on evidence-based medicine has become an important breakthrough in this scientific issue. Therefore, based on evidence-based medicine, we established the research concept that "originating from clinic, testing in experiment, returning to clinic". Taking the classic formula (Jinqi Jiangtang formula) treating diabetes as an example to find characteristic markers of diabetes supported by evidence-based medicine from clinic. We used the reverse analysis strategy of the response of characteristic markers to explore the intervention mechanism of Jinqi Jiangtang formula on characteristic markers. Then, we verified the key signaling molecules of the metabolic regulation of the Jinqi Jiangtang formula in clinic. The research ideas and key technologies for the mechanism of treatment of diabetes by Jinqi Jiangtang formula based on evidence-based medicine are formed, and it is expected to provide research reference for explaining the mechanism of dominant diseases in traditional Chinese medicine based on evidence-based medicine.

[Expert consensus on prescription comment of Chinese traditional patent medicine for promoting the rational use of drugs in Beijing].

Due to the complexity of Chinese medicine theory and the uncertainty of clinical application, the prescription review of Chinese patent medicine always relied on experience in their respective, leading to the uncontrolled of clinical rational use. According to the traditional Chinese medicine (TCM) theory and characteristics of the unique clinical therapeutics, based on the practice experience and expertise comments, our paper formed the expert consensus on the prescription review of Chinese traditional patent medicine for promoting the rational use of drugs in Beijing. The objective, methods and key points of prescription review of Chinese patent medicine, were included in this expert consensus, in order to regulate the behavior of prescription and promote rational drug use.

[Effect of Xinling Wan in treatment of stable angina pectoris: a randomized, double-blinded, placebo parallel-controlled, multicenter trial].

To evaluate the effectiveness and safety of Xinling Wan on patients with stable angina pectoris, a randomized, double-blinded, placebo parallel-controlled, multicenter clinical trial was conducted. A total of 232 subjects were enrolled and randomly divided into experiment group and placebo group. The experiment group was treated with Xinling Wan (two pills each time, three times daily) for 4 weeks, and the placebo group was treated with placebo. The effectiveness evaluation showed that Xinling Wan could significantly increase the total duration of treadmill exercise among patients with stable angina pectoris. FAS analysis showed that the difference value of the total exercise duration was between experiment group (72.11±139.32) s and placebo group (31.25±108.32) s. Xinling Wan could remarkably increase the total effective rate of angina pectoris symptom score, and the analysis showed that the total effective rate was 78.95% in experiment group and 42.61% in placebo group. The reduction of nitroglycerin dose was (2.45±2.41) tablets in experiment group and (0.50±2.24) tablets in placebo group on the basis of FAS analysis. The decrease of symptom integral was (4.68±3.49) in experiment group and (3.19±3.31) in placebo group based on FAS analysis. Besides, Xinling Wan could decrease the weekly attack time and the duration of angina pectoris. PPS analysis results were similar to those of FAS analysis. In conclusion, Xinling Wan has an obvious therapeutic effect in treating stable angina pectoris, with a good safety and a low incidence of adverse event and adverse reaction in experiment group.

Therapeutical effect of intrapleural perfusion with hyperthermic chemotherapy on malignant pleural effusion under video-assisted thoracoscopic surgery.

BACKGROUND: Patients with malignant pleural effusions (MPEs) have limited life expectancy. This study aims to investigate the feasibility of intrapleural perfusion with hyperthermic chemotherapy (IPHC) under video-assisted thoracoscopic surgery on MPE patients. METHODS: MPE patients were enrolled in the study and treated with IPHC. The treatment response was classified as complete response (CR, no re-accumulation of pleural fluid for 4 weeks), partial response (PR, re-accumulation above the post-IPHC level but below the pre-IPHC level for four weeks), no response (NR; re-accumulation or above the pre-IPHC level). The change of Karnofsky performance score (KPS) and tumour markers were also recorded. Follow-up was done every two weeks during first month and monthly thereafter until death. RESULTS: Eighty patients included 46 males and 34 females were included in the study. The total response rate was 100%, with 71.3% of CR and 28.7% of PR. The KPS scores were significantly elevated and the level of tumour markers in pleural effusion were dramatically decreased after IPHC. The median survival was 16.8 months ranged from 2.1 to 67.4 months. One-year and two-year survival rates were 82.5% and 23.8%, respectively. There were no serious clinical compilations during IPHC treatment. CONCLUSIONS: IPHC is a safety, effective and promising approach for MPE patients. It provides well survival benefit and minor toxicities.

Biatractylolide Modulates PI3K-Akt-GSK3ß-Dependent Pathways to Protect against Glutamate-Induced Cell Damage in PC12 and SH-SY5Y Cells.

Biatractylolide, isolated from the ethyl acetate extract of Atractylodes macrocephala, has shown various pharmacological activities such as antitumor and antioxidant activities. In this work, we aim to study the protective effect of biatractylolide on glutamate-induced rat adrenal pheochromocytoma cell (PC12) and human bone marrow neuroblastoma cell line (SH-SY5Y) injury and preliminarily explore its mechanism. The results showed that glutamate was cytotoxic with an inhibitory concentration 50% (IC50) of 8.5 mM in PC12 and 10 mM in SH-SY5Y cells. In this work, the preincubation with biatractylolide (10, 15, and 20 µM) observably improved cell viability, inhibited the apoptosis of cells induced by glutamate, and reduced the activity of LDH. AO staining revealed that apoptosis of cells was decreased. Additionally, the results of western blotting manifested that pretreatment with biatractylolide could downregulate GSK3ß protein expression and upregulate p-Akt protein expression, thereby protecting PC12 and SH-SY5Y cells from injury. All these findings indicate that biatractylolide has a neuroprotective effect on glutamate-induced injury in PC12 and SH-SY5Y cells through a mechanism of the PI3K-Akt-GSK3ß-dependent pathways.

[Effects and mechanism of Angelicae Sinensis Radix on Th1/Th2 and Th17/Treg in mice with asthma and Yin deficiency syndrome].

Angelicae Sinensis Radix, with nourishing Yin, promoting blood circulation, and moisturizing dryness functions, is commonly used in clinical medicine. In order to investigate the effects and mechanism of Angelica sinensis(AS) on Th1/Th2 and Th17/Treg in mice with asthma and Yin deficiency syndrome, asthmatic and Yin deficiency syndrome Balb/c mice models were established by injecting and inhaling ovalbumin(OVA) and thyroxin. The models were treated with dexamethasone(DXM), AS extract and AS extract+DXM, respectively. Pathological examination of lung tissues was conducted by HE staining, and ELISA was used to detect the levels of IL-4, IL-17, IFN-γ, TGF-ß as well as retinoic acid receptor-related orphan receptor (RORγt). Results showed that AS could significantly improve the situation of inflammation infiltration, increase ratios of IFN-γ/IL-4 and TGF-ß/IL-17, decrease the levels of RORγt in lung tissues. The AS+DXM group showed a best treatment effect. The results indicated that AS played a therapeutic role for asthma with Yin deficiency syndrome and improved airway inflammation by inhibiting the expression of RORγt in lung tissues and regulating the balance of Th1/Th2 and Th17/Treg.

Correlation of liver stiffness measured by FibroTouch and FibroScan with Ishak fibrosis score in patients with chronic hepatitis B / 中华肝脏病杂志

Objective@#To investigate the correlation of liver stiffness measured by FibroTouch (FT) and FibroScan (FS) with Ishak fibrosis score in patients with chronic hepatitis B.@*Methods@#A total of 313 patients with chronic hepatitis B who visited Department of Liver Cirrhosis in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from November 2014 to May 2016 were enrolled. All the patients underwent liver biopsy, and FT and FS were used to determine liver stiffness measurement (LSM). Serum biochemical parameters were measured, and the aspartate aminotransferase-to-platelet ratio index (APRI) in a multi-parameter model of liver fibrosis and fibrosis-4 (FIB-4) index were calculated. The consistency between the results of four noninvasive examinations and Ishak fibrosis score was compared. The t-test was used for comparison of LSM determined by FT and FS. Pearson correlation analysis was used investigate the correlation between LSM determined by FT and FS; Spearman correlation analysis was used to investigate the correlation of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels and Knodell score with LSM determined by FT and FS; the correlation between LSM determined by FT and FS and fibrosis stage was analyzed by partial correlation analysis adjusted by Knodell score for liver inflammatory activity; Spearman correlation analysis was used for APRI, FIB-4, and fibrosis stage. Based on the Ishak fibrosis score, the receiver operating characteristic (ROC) curve was used to analyze the values of four noninvasive methods in the diagnosis of liver fibrosis.@*Results@#There was no significant difference in LSM measured by FT and FS in all patients (15.75±9.42 kPa vs 15.42±10.52 kPa, P > 0.05) and Pearson correlation analysis indicated a significant positive correlation between them (r = 0.858, P < 0.01); serum ALT and AST levels and liver inflammatory activity were correlated with LSM determined by FT and FS. There was a significant positive correlation between LSM determined by FT and FS and fibrosis stage (r = 0.501 and 0.526, both P < 0.001), and APRI and FIB-4 were also positively correlated with fibrosis stage (r = 0.236 and 0.218, both P < 0.001). Based on the Ishak fibrosis score, in the diagnosis of fibrosis stages F3, F4, F5, and F6, the areas under the ROC curve were 0.915/0.856/0.839/0.816 for FT, 0.933/0.883/0.849/0.856 for FS, 0.618/0.630/0.608/0.638 for APRI, and 0.614/0.624/0.595/0.649 for FIB-4, and FT and FS had a significantly larger areas under the ROC curve than APRI and FIB-4.@*Conclusion@#LSM determined by FT or FS has a good correlation with the Ishak fibrosis score, so FT and FS have a significantly better diagnostic performance for liver fibrosis than APRI and FIB-4.
