Clinical Observation of Xiaotan Tongluo Gel Combined with Mecobalamin Tablets in Ttreating Peripheral Neurotoxicity Induced by Chemotherapy / 中国中医药信息杂志

Objective To investigate clinical efficacy of Xiaotan Tongluo Gel combined with mecobalamin tablets in treating chemotherapy-induced peripheral neuropathy (CIPN). Methods Totally 67 cases of CIPN were divided into the treatment group (36 cases) and the control group (31 cases). Both groups were given mecobalamin tablets, 0.5 mg each time, three times a day, orally. Patients in the treatment group were treated with Xiaotan Tongluo Gel for external use at the same time. The patients in control group were treated with placebo gel for external use, 1 mL/cm2, rubbed on the skin 1 cm more than sensory obstruction in diameter. The treatment for both groups lasted for 14 d as a treatment course, and the treatment lasted for 2 courses. The changes of peripheral nerve toxicity, TCM syndrome scores and the nerve conduction velocity were observed in the two groups. Results On the 14th and 28th days of treatment, the total effective rates of peripheral nerve toxicity were 75.00% and 91.67% in the treatment group, and 38.71% and 67.74% in the control group, and the treatment group was significantly better than those of the control group (P=0.002, P=0.005); On the 14th and 28th days of treatment, the total effective rate of TCM efficacy in the treatment group was 75.00% and 94.44% respectively, and that in the control group was 45.16% and 64.52% respectively, and the treatment group was significantly better than the control group (P=0.018, P=0.005). Compared with before treatment, the TCM syndrome scores in both groups were significantly reduced on the 14th and 28th days (P＜0.01); The TCM syndrome scores in the treatment group were significantly lower than those in the control group at the same time points after treatment (P＜0.01). Compared with before treatment, the sensory and motor nerve conduction speeds of the peroneal and median nerves in the two groups at 14th and 28th days were significantly increased (P＜0.01); Comparing the two groups at the same time point after treatment, the sensory and motor nerve conduction velocity of the peroneal and median nerves in the treatment group was significantly better than that in the control group (P＜0.05, P＜0.01). Conclusion Xiaotan Tongluo Gel combined with mecobalamin tablets can effectively improve the peripheral neurotoxicity induced by chemotherapy, TCM syndrome scores, and the nerve conduction velocity.

Therapeutic effect of Jinlongshe Granule () on quality of life of stage IV gastric cancer patients using EORTC QLQ-C30: A double-blind placebo-controlled clinical trial / 中国结合医学杂志

<p><b>OBJECTIVE</b>To evaluate the impact of Jinlongshe Granule (, JLSG) on quality of life (QOL) of stage IV gastric cancer patients.</p><p><b>METHODS</b>This randomized, double-blind and placebo-controlled clinical trial included 50 patients with advanced gastric cancer. They were equally randomized into a JLSG group and a placebo group. Patients in both groups received routine Chinese herbal decoctions according to Chinese medicine (CM) treatment based on syndrome differentiation. Patients in JLSG group received additional JLSG, and those in the placebo group received an additional placebo. In the JLSG group, 19 patients who completed the study were used for analysis. In the placebo group, finally the data of 20 patients who completed the study were used for analysis. The treatment course was at least 3 months, and the follow-up duration was at least 6 months in 5 interviews. Repeated measurements of the subscale items and individual items in European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire C30 (EORTC QLQ-C30) obtained at the 5 interviews were compared using different patient groups, changes over time and changes within one group over time independently to observe the tendency of changes in the scores.</p><p><b>RESULTS</b>Using time as the variant, there was signifificant difference in 4 functional scales (physical, role, emotional and social, P<0.05), 3 symptom scales (fatigue, nausea and vomiting and pain,P<0.05) and a global health status/QOL scale (P<0.05) and 6 single symptoms dyspnoea (P>0.05), insomnia (P<0.05), appetite loss (P<0.05), constipation (P<0.05), diarrhea (P>0.05) and financial difficulties (P<0.05). There was also signifificant difference in these items between the two groups when the placebo group and group over time were used as variants (P<0.05 or P<0.01).</p><p><b>CONCLUSION</b>Additional use of JLSG on the basis of routine CM treatment could improve the somatic function, role function, emotional function, social function, cognitive function and general QOL of patients with advanced gastric cancer, and relieve the symptoms of fatigue, nausea and vomiting, pain, loss of appetite and constipation.</p>

Establish and optimization of real-time fluorescent reverse transcription loop-mediated isothermal amplification for detection of avian influenza H5 hemagglutinin gene / 病毒学报

H5 subtype avian influenza (AIV-H5) is a major causative agent of animalloimia a rapid and sensitive molecular biological diagnosis is crucial to the control program of AIV-H5. AIV-H5 real-time fluorescent reverse transcription loop-mediated isothermal amplification (qRT-LAMP) was established by means of heat treatment of the samples. The sensitivity, specificity and repeatability of this method were assessed and the performance of Calcein,SYBR Green I,HNB,SYTO 81 in colorimetric detection was comparatively analyzed to screen the optimum dye. The results showed the sensitivity of this method was 100 times higher than that of standard real-time fluorescent RT-PCR, and the detection limit was one copy of the gene per reaction. This method had no cross-reactivity with other common avian respiratory tract infectious disease-related pathogens such as IBV and NDV. The present study suggested Calcein was the optimum dye. Small-scale tests suggested this method was reliable for survey monitoring of AIV-H5 on the spot, indicating its potential applications in field investigation.

Study on analgesic effect of traditional Chinese medicine / 中国结合医学杂志

Chinese medicine has been used in treating pain for a long time. Much progress has been made in studies on the mechanism of the analgesic effect of Chinese medicine in animal experiments. It is found that the analgesic action may be related to the following actions: (1) Reducing the secretion of peripheral algogenic substances and inducing the secretion of pain-sensitive substances; (2) Alleviating the accumulation of local algogenic substances; (3) Increasing the release of endogenous analgesic substances; (4) Regulating c-fos gene and increasing the secretion of such substances in the central nervous system, etc. In this paper, the experimental methods and analgesic effect of Chinese medicines are reviewed.
