Characteristics of Chinese Medicine Education Under British Education System in New Zealand

Abstract

With the globalisation of Chinese medicine (CM), the local CM education institutions were established in many other countries outside of China. These CM education institutions have formed a new mode in CM education after integrating with local culture, law and national conditions. This article takes New Zealand CM education institutions as an example to discuss the characteristics of CM education under the British education system, aiming to provide ideas on CM education in China and other countries.

Correlation Analysis of Rubella Incidence and Meteorological Variables Based on Chinese Medicine Theory of Yunqi

Abstract

Objective

To analyze the correlations between the incidence of rubella and meteorological factors over the same period and previous periods including 1, 2, 3 and 4 year ago (defined according to Chinese medicine Yunqi theory of "pestilence occurring after 3 years") and establish the rubella-meteorological forecast models for Beijing area, China.

Methods

Data regarding the incidence of rubella between 1990 and 2004 from Beijing Center for Disease Control and Prevention, and the meteorological variables including daily average temperatures, daily average wind speeds, average precipitations, average relative humidity, average vapor pressures and average low cloud covers between 1986 and 2004 were collected from the Beijing Meteorological Observatory. Descriptive statistics and back-propagation artificial neural network for forecast model’s establishment were adopted for data analysis.

Results

The average temperature and relative humidity have a great contribution (100%) to the rubella morbidity. But the combination of other meteorological factors contributed to improve the accuracy of rubella-meteorological forecast models. The forecast accuracy could be improved by 76% through utilizing a combination of meteorological variables spanning from 3 years ago to the present rather than utilizing data from a single year or dating back to more earlier time than 3 years.

Conclusions

There is a close relationship between the incidence of rubella and meteorological variables in current year and previous 3 years. This finding suggests that rubella prediction would benefit from consideration to previous climate changes.

Post-marketing Re-evaluation of Tongxiening Granules (痛泻宁颗粒) in Treatment of Diarrhea-Predominant Irritable Bowel Syndrome: A Multi-center, Randomized, Double-Blind, Double-Dummy and Positive Control Trial

Abstract

Objective

To evaluate the efficacy and safety of Tongxiening Granules (痛泻宁颗粒, TXNG) in the treatment of irritable bowel syndrome with predominant diarrhea (IBS-D).

Methods

A randomized, double-blind, double-dummy, and positive parallel controlled clinical trial was conducted from October 2014 to March 2016. Totally 342 patients from 13 clinical centers were enrolled and randomly assigned (at the ratio of 1:1) to a treatment group (171 cases) and a control group (171 cases) by a random coding table. The patients in the treatment group were administered orally with TXNG (5 g per time) combined with pinaverium bromide Tablet simulator (50 mg per time), 3 times per day. The patients in the control group were given TXNG simulator (5 g per time) combined with pinaverium bromide Tablets (50 mg per time), 3 times per day. The treatment course lasted for 6 weeks. The improvement of Irritable Bowel Syndrome Symptom Severity Score (IBS-SSS) was used to evaluate the primary outcome. Secondary outcomes included adequate relief (AR) rate, Irritable Bowel Syndrome-Quality of Life Questionnaire (IBS-QOL), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), and the recurrence rate at follow-ups. Safety indices including the adverse events (AEs) and related laboratory tests were evaluated.

Results

Primary outcome: IBS-SSS at baseline, weeks 2, 4, 6 showed no statistical significance in both full analysis set (FAS) and per protocol set (PPS, P>0.05). After 6 weeks of treatment, the total effective rate of IBS-SSS scores in the treatment group (147/171,86.0%) was higher than the control group (143/171, 83.6%) by FAS (P>0.05). In regard to secondary outcomes, after 6-week treatment, there was no significant difference in AR rate, total score of IBS-QOL, improvement of HAMD and HAMA total scores between the two groups (P>0.05). The recurrence rate at 8-week follow-up was 12.35% (10/18) in treatment group and 15.79% (12/76) in control group, respectively (P>0.05). A total of 21 AEs occurred in 15 cases, of which 11 occurred in 8 cases in the treatment group and 10 AEs in 7 cases in the control group. The incidence of AEs had no statistical significance between the two goups (P>0.05).

Conclusion

Tongxiening Granules could relieve the symptoms of patients with IBS-D and the treatment effect was comparable to pinaverium bromide. (No. ChiCTR-IPR-15006415)

Anti-obesity Effects of Ginsenosides in High-Fat Diet-Fed Rats

Abstract

Objective

To examine the anti-obesity effects of ginsenosides in Korea Red Ginseng (KRG, Panax ginseng) in rats fed with a high-fat diet (HFD).

Methods

Twenty-five 4-week-old obesity rats after receiving an HFD for 5 weeks; subsequently, they were additionally treated with ginsenosides Rb1, Rd, Rg1, or Re (10 mg/kg, intraperitoneal injection) for a further 3 weeks (n=5 in each group). The control rats were fed a normal diet. The food consumption, body weight, locomotor activity, serum lipids, adipose tissues, nitric oxide (NO) expression, leptin, neuropeptide Y (NPY), cholecystokinin (CCK) in the brains were measured.

Results

In the HFD-fed rats, body weight, body fat mass, serum levels of leptin and NO were significantly higher than in the control rats (P<0.05 or P<0.01). However, the treatment of Rd, Re, and Rb1 markedly decreased body fat mass and body weight (P<0.05). The serum level of leptin and NO in ginsenoside-treated rats were markedly lower than the control group (P<0.01). The expression of NPY and CCK in the hypothalamic nuclei showed insignificant difference among groups. However, the expression of NPY immunoreactive neurons in the hypothalamus was significantly reduced in the Rb1-treated group (P<0.05).

Conclusion

PD-type ginsenoside Rb1 from the crude saponins of KRG may be a useful compound for the treatment of obesity and related disorders through the modulation of peripheral and central appetite-regulating signals.

Comparison between Xingnaojing Injection (醒脑静注射液) and Naloxone in Treatment of Acute Alcohol Intoxication: An Updated Systematic Review and Meta-Analysis of Randomized Controlled Trials

Abstract

Objectives

To investigate the effectiveness and safety of Xingnaojing Injection (XNJ, 醒脑静注射 液) compared with naloxone for the treatment of acute alcohol intoxication (AAI), and provide the latest evidence through evidence-based approach.

Methods

Seven electro-databases including PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure Databases, Chinese Biomedical Literature Database, Chinese Science and Technology Periodical Database (VIP) and Wanfang Database were searched from the inception to January 2018. Randomized controlled trials (RCTs) comparing XNJ with naloxone for patients with AAI and reporting at least one of the below outcomes were included: patients' conscious recovery time, stay length in emergency department, disappearance time of the ataxia symptom, the severity of the symptoms, the blood alcohol content as well as the adverse events. Methodological quality of included trials was assessed using the risk of bias tool which recommended by the Cochrane Collaboration. Meta-analysis was conducted by Review Manager 5.3 software.

Results

Totally 141 trials with 13,901 patients were included in this review, all of them were assessed as unclear or high risk of bias. Results showed that on the basis of routine therapy, standard dose XNJ (10–20 mL) may have similar results with naloxone on the recovery time of consciousness (MD 12 min, 95% CI 7.2–17.4 min) and disappearance time of symptoms (MD 6 min, 95% CI–13.8–25.8 min) for patients with AAI. Larger dose of XNJ Injection (21–40 mL) may speed up the time (almost 1 h earlier). Combination of XNJ and naloxone seemed superior to the naloxone alone for all the relevant outcomes. The average difference of time in consciousness recovery was 2 h and the number of AAI patients whose consciousness recovery within 1 h was above 50% the combination group than in the control group (RR 1.42, 95% CI 1.29 to 1.56). No severe adverse events or adverse reactions of XNJ were reported in the included trials.

Conclusions

Low quality of evidence showed XNJ may have equal effect as naloxone and may achieve better effect as add-on intervention with naloxone for patients with AAI. We failed to evaluate the safety of XNJ Injection due to the insufficient evidence in this review. Registration number. in PROSPERO (No. CRD42018087804)

Panaxdiol Saponins Component Promotes Hematopoiesis and Modulates T Lymphocyte Dysregulation in Aplastic Anemia Model Mice

Abstract

Objective

To investigate the potential efficacy of panaxadiol saponins component (PDS-C) in the treatment of aplastic anemia (AA) model mice.

Methods

Totally 70 mice were divided into 7 groups as follows: normal, model, low-, medium-, high-dose PDS-C (20, 40, 80 mg/kg, namely L-, M-, H-PDS-C), cyclosporine (40 mg/kg), and andriol (25 mg/kg) groups, respectively. An immune-mediated AA mouse model was established in BALB/c mice by exposing to 5.0 Gy total body irradiation at 1.0 Gy/min, and injecting with lymphocytes from DBA mice. On day 4 after establishment of AA model, all drugs were intragastrically administered daily for 15 days, respectively, while the mice in the normal and model groups were administered with saline solution. After treatment, the peripheral blood counts, bone marrow pathological examination, colony forming assay of bone marrow culture, T lymphocyte subpopulation analysis, as well as T-bet, GATA-3 and FoxP3 proteins were detected by flow cytometry and Western blot.

Results

The peripheral blood of white blood cell (WBC), platelet, neutrophil counts and hemoglobin (Hb) concentration were significantly decreased in the model group compared with the normal group (all P<0.01). In response to 3 dose PDS-C treatment, the WBC, platelet, neutrophil counts were significantly increased at a dose-dependent manner compared with the model group (all P<0.01). The myelosuppression status of AA was significantly reduced in M-, H-PDS-C groups, and hematopoietic cell quantity of bone marrow was more abundant than the model group. The colony numbers of myeloid, erythroid and megakaryocytic progenitor cells in the model group were less than those of the normal mice in bone marrow culture, while, PDS-C therapy enhanced proliferation of hematopoietic progenitor cells by significantly increasing colony numbers (all P<0.01). Furthermore, PDS-C therapy increased peripheral blood CD3+ and CD3+CD4+ cells and reduced CD3+CD8+ cells (P<0.05 or P<0.01). Meanwhile, PDS-C treatment at medium- and high doses groups also increased CD4+CD25+FoxP3+ cells, downregulated T-bet protein expression, and upregulated GATA-3 and FoxP3 protein expressions in spleen cells (P<0.05).

Conclusion

PDS-C possesses dual activities, promoting proliferation hematopoietic progenitor cells and modulating T lymphocyte immune functions in the treatment of AA model mice.

Anticancer Effects of Constituents of Herbs Targeting Osteosarcoma

Abstract

Osteosarcoma is a rare primary malignancy of bone that is prone to early metastasis. Resection surgery and chemotherapeutic regimens are current standard treatments for osteosarcoma. However, the long-term survival rate of patients with osteosarcoma is low due to a high risk of metastasis. Hence, a new approach is urgently needed to improve the treatment of osteosarcoma. Compared with chemotherapy, natural active constituents isolated from herbs exhibit less adverse effects and better anti-tumor effects. This study aimed to summarize the anticancer effects of constituents of herbs on the progression and metastasis of osteosarcoma cells. It showed that many constituents of herbs inhibited osteosarcoma by targeting proliferation, matrix metalloproteinases, integrin and cadherin, and angiogenesis. The findings might be beneficial for the development of new drugs and treatment strategies.

Ultrastructure Characteristics of Different Chinese Medicine Syndromes of Helicobacter pylori -Correlated Gastric Diseases

Abstract

Objective

To explore the ultrastructure characteristics of patients with dampness-heat of Pi (Spleen)-Wei (Stomach) syndrome (DHPW) and Pi-qi deficiency syndrome (PQD), both of which are Helicobacter pylori (Hp)-correlated gastric diseases (HPCG), and implicate a helpful hint for the clinical microcosmic syndrome differentiation.

Methods

Fourteen gastric mucosa samples from 6 chronic gastritis (CG) and 6 active peptic ulcer (including 8 DHPW, 4 PQD) as well as 2 healthy volunteers were collected and tested for Hp infection. The ultrastructure of gastric mucosa was observed under the transmission electron microscope (TEM).

Results

Among 14 gastric mucosa samples, 8 of them were Hp positive (6 DHPW and 2 PQD), which were all accordance with the results screened by supermicro-pathological method. Under TEM, the normal gastric mucosa, with tidy microvilli and abundant in mucus granules, mitochondria and rough endoplasmic reticulum distributed evenly, and with smooth nucleus membrane. But in those specimens of DHPW with Hp infection, microvilli were presented with burr shape. Especially, those samples from dampness-heat syndrome with predominant heat type (DHSH) patients were more obvious, with microvilli damaged, mitochondria concentrated and distributed in disorder, secretory tubule extended. In dampness-heat syndrome with predominant dampness type (DHSD) patients, mucus granules aggregated obviously, mitochondria swelled and blurred, and rough endoplasmic reticulum crowded. For 2 samples of DHPW without Hp infection, their microvilli were intact, with mitochondria increased and gathered but well-distributed, and secretory tubule extended mildly. In 2 PQD patients with Hp positive, the specimens of microvilli were sparse, and their mucus granules and mitochondria were decreased, with fractured crests and vacuole, secretory tubules extension to nucleus membrane, and rough endoplasmic reticulum extension in a pool-like way, and nucleus condensed. The 2 samples from PQD patients without Hp infection were characterized with intact microvilli, decreased mitochondria, fractured crest and extended rough endoplasmic reticulum in a pool-like way.

Conclusion

It’s obviously different in ultrastructure of DHPW and PQD patients under TEM, which may give a helpful hint for the microcosmic syndrome differentiation of HPCG.

Systems-Based Interactome Analysis for Hematopoiesis Effect of Angelicae sinensis Radix : Regulated Network of Cell Proliferation towards Hemopoiesis

Abstract

Objective

To explore the molecular-level mechanism on the hematopoiesis effect of Angelicae sinensis Radix (ASR) with systems-based interactome analysis.

Methods

This systems-based interactome analysis was designed to enforce the workflow of "ASR (herb)→compound→target protein→internal protein actions→ending regulated protein for hematopoiesis". This workflow was deployed with restrictions on regulated proteins expresses in bone marrow and anemia disease and futher validated with experiments.

Results

The hematopoiesis mechanism of ASR might be accomplished through regulating pathways of cell proliferation towards hemopoiesis with cross-talking agents of spleen tyrosine kinase (SYK), Janus kinase 2 (JAK2), and interleukin-2-inducible T-cell kinase (ITK). The hematopoietic function of ASR was also validated by colony-forming assay performed on mice bone marrow cells. As a result, SYK, JAK2 and ITK were activated.

Conclusion

This study provides a new approach to systematically study and predict the therapeutic mechanism for ASR based on interactome analysis towards biological process with experimental validations.
