[Clinical effects of matrix acupuncture on cervical spondylotic radiculopathy with nuchal ligament calcification].

OBJECTIVE: To observe the effects of matrix acupuncture on the neck disability index (NDI) score, clinical efficacy, and the calcification size of the nuchal ligament in patients of cervical spondylotic radiculopathy with nuchal ligament calcification. METHODS: A total of 120 cases were randomly divided into a matrix acupuncture group and a routine acupuncture group, with 60 cases in each group. In the matrix acupuncture group, Ashi-point, bilateral Tianzhu (BL10), bilateral Fengchi (GB20), bilateral Dazhu (BL11), bilateral Jianzhongshu (SI15), and Jianjing (GB21), Tianzong (SI11), Quchi (LI11), Shousanli (LI10), Waiguan (TE5), and Hegu (LI4) at the affected side were selected. In the routine acupuncture group, C3-C7 Jiaji points at the neck and Jianjing (GB21), Tianzong (SI11), Quchi (LI11), Shousanli (LI10), Waiguan (TE5), Hegu (LI4), and Ashi-point at the affected side were selected. The patients in the two groups were treated 30 min once, six days a week, for a total of four weeks. The NDI scores, clinical efficacies, and calcification sizes of nuchal ligament were compared between the two groups every wee-kend. RESULTS: After four weeks of treatment, the NDI scores and calcification volumes of nuchal ligament decreased in both groups (P<0.05). Compared with the routine acupuncture group, the matrix acupuncture group showed decreased NDI scores and reduced calcification volumes of nuchal ligament at the 1st, 2nd, 3rd, and 4th weeks of treatment (P<0.05). The cure and marked effective rate in the matrix acupuncture group at the 2nd, 3rd, and 4th weeks of treatment were superior to those of the routine acupuncture group (P<0.05). CONCLUSION: The matrix acupuncture group and the routine acupuncture group are effective in reducing the NDI score and calcification size of nuchal ligament in patients of cervical spondylotic radiculopathy with nuchal ligament calcification. However, matrix acupuncture has obvious advantages over routine acupuncture.

Solid alcohol based on waste cooking oil: Synthesis, properties, micromorphology and simultaneous synthesis of biodiesel.

Solid alcohols based on waste cooking oil (WCO) and other edible oils (butter or soybean oil) were synthesized by a simple one-step method. The effects of sodium hydroxide (NaOH) dosage and type of oil on the combustion performances were explored. IR spectroscopy and micro-morphologies of the oil based solid alcohols were also studied. Results showed that, for oil based solid alcohol, use of an appropriate excess of NaOH and an oil with lower iodine value produced the solid alcohol with better combustion performance. Centrifugation produced the bottom waste cooking oil (B-WCO) with lower iodine value and the supernatant waste cooking oil (S-WCO) with higher iodine value. The B-WCO afforded solid alcohol with longer combustion time, higher melting temperature and relatively low combustion residue rate, whereas the S-WCO could be used for synthesizing biodiesel.

Rheum palmatum extract exerts anti-hepatocellular carcinoma effects by inhibiting signal transducer and activator of transcription 3 signaling.

ETHNOPHARMACOLOGICAL RELEVANCE: Hepatocellular carcinoma (HCC) is among the most common malignancies. Signal transducer and activator of transcription 3 (STAT3), with abnormal expression and constitutive activation, has been reported to promote proliferation, metastasis, survival and angiogenesis of HCC cells. Rheum palmatum (RP), a traditional Chinese medicinal herb, exhibited tumor-suppressing effects in multiple human cancers, but its potential functions in HCC remain unexplored. AIM OF THE STUDY: This study aimed to examine the involvement of STAT3 signaling in the anti-HCC effects of RP extract. MATERIALS AND METHODS: SMMC-7721 and HepG2 HCC cell lines were treated with RP extract for 24 h, and then viability, migration, and invasion of HCC cells and angiogenesis of human umbilical vein endothelial cells (HUVECs) were analyzed using MTS, wound-healing, Transwell invasion and tube formation assays, respectively. Western blotting and immunohistochemistry (IHC) were used to examine the activation of key molecules in STAT3 signaling, including STAT3, JAK2, and Src. Additionally, we explored the in vivo antitumor effects of RP extract in a xenograft tumor nude mouse model of HCC. RESULTS: The result showed that RP extract reduced viability, migration, and invasion of SMMC-7721 and HepG2 cells and angiogenesis of HUVECs. It suppressed the phosphorylation of STAT3 and its upstream kinases including JAK2 and Src. In addition, RP extract treatment downregulated STAT3 target genes, including survivin, Bcl-xL, Mcl-1, Bcl-2, MMP-2, MMP-9, Cyclin D1, CDK4, c-Myc, and VEGF-C. Furthermore, RP extract suppressed the xenograft tumor growth and activation of STAT3 in xenograft tumor mice. CONCLUSION: Collectively, the results showed that RP extract prevented HCC progression by inhibiting STAT3, and might be useful for the treatment of HCC.

Salvianolic acid B attenuates oxidized low-density lipoprotein-induced endothelial cell apoptosis through inhibition of oxidative stress, p53, and caspase-3 pathways.

OBJECTIVE: To investigate the effect of salvianolic acid B (Sal B) on oxidized low-density lipoprotein (ox-LDL)-induced human umbilical vein endothelial cells (HUVECs) apoptosis and the possible mechanism. METHODS: HUVECs were divided into 6 groups, including control group, ox-LDL group, vitamin C group (positive control), and 5, 10 and 20 µg/mL Sal B groups. Cell viability of HUVECs was determined by 3-(4,5-dimethylthiazol- 2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The anti-apoptotic effect of Sal B was tested by Hoechst 33258 staining and Annexin V/propidium iodide flflow cytometry analysis. Apoptosis-related genes (p53, Bcl-2 and Bax) expression and caspase-3 activity were also determined. Oxidative stress markers malondialdehyde (MDA) and superoxide dismutase (SOD) were determined by the corresponding kits. RESULTS: In HUVECs, ox-LDL signifificantly reduced cell viability and induced apoptosis (P<0.05 or P<0.01), however, Sal B diminished the effects of ox-LDL in a dose-dependent manner (P<0.05). Moreover, 10 and 20 µg/mL Sal B reduced the expression levels of p53, increased the Bcl-2/Bax ratio and inhibited the caspase-3 activity in ox-LDL-treated HUVECs (P<0.05). In addition, 5, 10 and 20 µg/mL Sal B signifificantly enhanced the activity of SOD, while decreased the level of MDA in the HUVECs which treated with ox-LDL (P<0.05). CONCLUSION: Sal B exhibited anti-apoptotic effects in ox-LDL-induced endothelial cell injury by suppressing oxidative stress, p53, and caspase-3.

[Therapeutic Efficacy of Multigly-Cosidorum Tripterygium Combined with rhIL-11 for Immune Thrombocytopenia].

OBJECTIVE: To study the therapeutic efficacy of multigly-cosidorum Tripterygium combined with rhIL-11 for treating patients with immune thrombocytopenia (ITP). METHODS: A total of 75 patients with ITP were divided into 2 group: experimental group and control group. The experimental group included 40 patients who had been treated with multigly-cosidorum Tripterygium combined with rhIL-11. Multigly-cosidorum Tripterygium was given at a dose of 1mg/kg·d for 2 months and rhIL-11 was injected at a dose of 16,000,000 units per day. Control group included 35 patients who had been treated with prednisone at a dose of 1 mg/kg·d. Platelet counts were performed every day before platelet counts >30 × 109/L. Peripheral blood T cells were collected before and after treated for 2 months. The ratios of CD4⁺, CD8⁺ T cells in peripheral blood T cells were analyzed by flow cytometry. RESULTS: Totally effective rate in experimental group was 77.5%. Totally effective rate in control group was 82.9%. Totally effective rate showed no statistical difference between these two groups (P > 0.05). The average time of platelet count 30 × 109/L in experimental and control groups were 13.06 ± 6.10 days and 9.76 ± 5.71 days respectively; in experimental group, the ratio of CD4⁺ T cells in peripheral blood was 21.03% before treatment, then rised to 34.49% after treatment for 2 months (P < 0.01); The ratio of CD8⁺ T cells in peripheral blood was 26.35% before treatment, then decreased to 20.18% (P < 0.01). In control group, the ratio of CD4⁺ T cells was 22.30% before treatment, then rised to 25.11% after treatment for 2 months (P < 0.05); The ratio of CD8⁺ T cells in peripheral blood was 27.24% before treatment, then decreased to 21.35% (P < 0.01). CONCLUSION: Multigly-cosidorum tripterygium can correct disorder of T lymphocytes, the combination of multigly-cosidorum triptergium and rhIL-11 can accelerate therapeutic efficacy for treating ITP and with less adverse reaction, so this combination may be effective and safe for treating patients with ITP.

Epidemiological trends and the advances of treatments of amphetamine-type stimulants (ATS) in China.

BACKGROUND AND OBJECTIVES: Amphetamine-type stimulants (ATS) have quickly spread and been widely abused in many parts of the world, particularly in China. This review focuses on and describes the epidemiological trends and the advances of treatments of ATS in China. METHODS: A descriptive study based on literature identified from searches of the China National Knowledge Infrastructure (1979-2013), PubMed databases, hand-picked references, and online references with emphasis on epidemiology, treatment and traditional Chinese medicine. This review covers some traditional Chinese treatments and their complementary Western approaches. RESULTS AND CONCLUSIONS: The epidemiological trends of ATS in China have led to its being 2.2 times the rate of morphine abuse and second only to marijuana abuse. The treatment programs in China have used traditional herbal approaches as well as acupuncture, often in combination with Western medications such as fluoxetine for depression associated with ATS abuse. Other herbal treatments have reversed the cardiac arrhythmias associated with ATS intoxication, and acupuncture has been used successfully for the protracted depressive and somatic symptoms of ATS withdrawal over a period of 3 months. SCIENTIFIC SIGNIFICANCE: These traditional Chinese treatments may be increasingly available to the world, but will remain a consistent complementary therapy for ATS in China and the Far East, where ATS has become such a prevalent problem.

[Evaluation on reducing effect of eye drop on herpes simplex virus-I in vitro].

OBJECTIVE: To observe the effect of herbal eye drop Reduqing (clearing toxic heat) on herpes simplex virus (HSV) on the cytopathic effect in cell culture in vitro. METHODS: The maximal non-toxic Reduqing eye drop concentration added to cell culture infected with 100 and 10TCID50 of herpes simplex virus? (HSV-1) to observe the inhibitory effect of the medicine on HSV-I induced cytopathic effect. RESULTS: The Reduqing eye drop at maximal non-toxic concentration could obviously inhibit the cytopatic effect induced by 100TCID50 and 10TCID50 HSV-I. No statistically significant difference was found when compared with 0.1% acyclovir eye drop (P>0.05), on cytopathic effect occurred with boty eye drops. However, there was significant difference when compared with control group(P<0.05). The inhibitory effect of concentrations of Reduqing at 500,000 and 63,000 microg/L was stronger than that of 2,000,000 and 1,000,000 microg/L (P 0.01). The maximal tolerable concentration of Reduqing eye drop by the cell was 2,000,000 microg/L (1:80 dilution), which was higher than that of 5,000 microg/L(1:400 dilution) acyclovir eye drop. CONCLUSIONS: These results suggest that Reduqing eye drop could markedly inhibit the cytopathic effects caused by HSV-I. The Reduqing eye drop showed remarkably low toxic effect to the cells as compared to acyclovir eye drop.
