Combined Effects of Electroacupuncture and Behavioral Training on Learning-Memory Ability and Event-Related Potential P300 in Rats with Mid/Advanced Cerebral Infarction / 中华医学杂志(英文版)

<p><b>Background</b>The effectiveness of the combination of electroacupuncture (EA) and behavioral training (BT) for mid/advanced cerebral infarction (M/ACI) and related mechanisms remains unclear. This study aimed to investigate the combined effects on the learning-memory ability and event-related potential P300 in rats with M/ACI.</p><p><b>Methods</b>Eighty rats with M/ACI were divided into Group Model (M), Group EA, Group BT, and Group EA-BT (n = 20) according to the random number with five healthy rats in Group Control (CON). On the 6 week after modeling, EA, BT, and EA-BT were given to Group EA, Group BT, and Group EA-BT, respectively, whereas Group M and Group CON were not given any intervention. Y-maze test and P300 were recorded before and after the intervention.</p><p><b>Results</b>After intervention, the P300 latency was lower and the amplitude was higher in the Group EA-BT, Group EA, and Group BT than before (for latency, t = -7.638, -4.334, and -5.916; for amplitude, t = 8.125, 3.846, and 5.238; P < 0.01), with Group EA-BT superior to Group EA (for latency, t = -3.708; for amplitude, t = 3.653; P < 0.01) and Group BT (for latency, t = -2.067; for amplitude, t = 2.816; P < 0.05), with no significant difference between Group BT and EA (for latency, t = -1.439; for amplitude, t = 1.075; P > 0.05). While the performances of Y-maze tests in the Group EA-BT, Group EA, and Group BT were all better than before (t = 10.359, 4.520, and 7.791, P < 0.01), with Group EA-BT better than Group EA (t = 5.627, P < 0.01) and Group BT (t = 2.913, P < 0.01) respectively, and Group BT better than Group EA (t = 2.912, P < 0.01).</p><p><b>Conclusion</b>EA or BT can affect P300 in rats with M/ACI, and the combination of these two methods can significantly improve the learning-memory ability.</p>

Regulation effects of liuwei dihuang pill, jingui shenqi pill, jiangu erxian pill containing serums on adipogenic and osteogenic differentiation-related genes expressions in the differentiation process of preadipocytes to osteoblasts / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the effects of Chinese medical recipes for invigorating Shen on rat bone marrow mesenchymal stem cells (BMSCs)-derived preadipocytes' differentiation to osteoblasts.</p><p><b>METHODS</b>The BMSCs were cultured using whole bone marrow adherence wall method. The BMSCs were induced to preadipocytes by classic chemical method. The osteogenic differentiation process of preadipocytes was intervened by Liuwei Dihuang Pill (LDP), Jingui Shenqi Pill (JSP), or Jiangu Erxian Pill (JEP)-containing serums (with the concentRation of 10%, on behalf of tonifying Shen yin, tonifying Shen yang, and tonifying Shen essence). Reverse transcription-real time fluorescent quantitative-PCR (RT real time qPCR) was used to detect RUNX2, ALP, BGP, BMP2, BMP4, SPP1, and IGF1 mRNA expressions of osteogenic differentiation-related genes, mRNA expressions of LPL, FABP4, and PPARgamma of adipogenic differentiation-related genes on the 6th, the 12th, and the 18th day.</p><p><b>RESULTS</b>As for the osteogenic differentiation-related gene, when compared with the control group, there was no statistical difference in the gene expression level in the experimental groups on the 6th day (2.0 > Ratio > 0.5). On the 12th day, the mRNA expressions of IGF1 and Runx2 increased more significantly in the JSP group, with their relative quantification (Ratio) being 2.97 and 1.81 respectively. On the 18th day the IGF1 mRNA expression significantly increased, being the Ratio value of 3.74, 12.60, and 8.35, respectively, in the LDP group, the JSP group, and the JEP group. The SPP1 mRNA expression also significantly increased, with the Ratio value of 2.94, 3.18, and 2.62, respectively, in the LDP group, the JSP group, and the JEP group. As for adipogenic differentiation-related genes, on the 6th day, when compared with the control group, FABP4 mRNA expression significantly decreased in the LDP group and the JSP group (with the Ratio value of 0.47 and 0.40 respectively). The expression levels of other genes were all down-regulated, but not significantly. On the 12th day and 18th day, there was no statistical change in the adipogenic differentiation-related genes expressions (2.0 > Ratio > 0.5).</p><p><b>CONCLUSIONS</b>Up-regulation of osteogenic differentiation-related genes expression occurred in later time, while down-regulation of adipogenic differentiation-related genes expression occurred in earlier time after treatment by Chinese medical recipes for invigorating Shen. In general, above data indicated that tonifying Shen yang was more effective in promoting osteogenic differentiation and inhibiting adipogenic differentiation of BMSCs.</p>

Acupoint catgut-embedding therapy: superiorities and principles of application / 中国针灸

<p><b>OBJECTIVE</b>To analyze the superiorities of acupoint catgut-embedding therapy, discuss its law of clinical application and provide scientific decision-making for clinical treatment.</p><p><b>METHODS</b>Literatures on acupoint catgut-embedding therapy in the recent 40 years were selected, input, examined and verified, picked up and analyzed by establishing database with the modern computer technology.</p><p><b>RESULTS</b>(1) One thousand and seventy-five literatures were input. It shows that the acupoint catgut-embedding therapy has an extensive application in all departments, especially in the internal department, accounting for 48.54% (50/103) of the total disease category. It has the most extensive application on treatment of epigastric pain, with the frequency of 102 times, and obesity of 74 times. The next is surgery, accounting for 14.56% (15/103). The major application is on low back pain and leg pain with the frequency of 79 times. Psoriasis, with the frequency of 30 times, holds the major application in dermatological department. And blepharoplasty, with the frequency of 30 times, gains the most application in department of ophthalmology and otorhinolaryngology. (2) In the included literatures, selection of adjacent acupoints and distal acupoints are held as the major method of acupoint selection. The adjusted lumbar puncture needle is taken as the major tool for the acupoint catgut-embedding therapy. And catguts of different sizes are adopted for the operation. (3) Analysis of the therapeutic effect shows that acupoint catgut-embedding therapy has obvious effect in all departments, especially in surgery and dermatology, with the total effective rate over 90%.</p><p><b>CONCLUSION</b>Epigastric pain, obesity, epilepsy, asthma, abdominal pain, facial paralysis and constipation of the internal medicine, low back pain and leg pain of the surgical department, psoriasis of the dermatological department and blepharoplasty of the department of ophthalmology and otorhinolaryngology are considered as the dominant diseases for acupoint catgut-embedding therapy.</p>
