The characteristics and rules of acupoint selection of acupuncture for trigeminal neuralgia were analyzed. By searching CNKI, VIP, WF, literature regarding acupuncture for trigeminal neuralgia from 1980 to 2013 was collected to establish an acupuncture prescription database. The data mining technology was applied to analyze the characteristics and rules of the acupoint selection. As a result, a total of 180 papers were included, involving 148 acupoints. It was found that the acupoints that had high frequency of selection included Hegu (LI 4), Xiaguan (ST 7), Fengchi (GB 20) and trigger points. The acupoints selected were distributed in 14 meridians, in which yangming meridian of hand-foot had a frequency of 41. 58%. The special acupoints including crossing points, yuan-primary points and five-shu points were widely used, accounting for 65. 9%. As for the branch of trigeminal nerve, the top-3 selected acupoints were Yangbai (GB 14), Yuyao (EX-HN 4), Cuanzhu (BL 2) in the first branch, Sibai (ST 2), Quanlian (SI 18), Yingxiang (LI 20) in the second branch, Jiache (ST 6), Xiaguan (ST 7), Dicang (ST 4) in the third branch. In conclusion, it is believed that the clinical treatment of trigeminal neural gia focuses on local acupoints in combination with nerve distribution-based acupoints and distal acupoints, also the special acupoints are emphasized.

Objective: To observe the clinical efficacy of acupuncture plus rehabilitation training in treating post-stroke deglutition disorders of qi-deficiency blood stasis pattern. Methods: Sixty-six patients with post-stroke deglutition disorders of qi-deficiency blood stasis patter were divided into an observation group and a rehabilitation group using the random number table method. The two groups both received conventional medications and supportive treatment for stroke. In addition, the observation group received acupuncture plus rehabilitation training while the rehabilitation group only received the same rehabilitation training. The interventions were conducted 3 times a week for a total of 4 weeks in both groups. They were evaluated using Kubota water swallowing test (KWST), Fujishima Ichiro food intake level scale (FILS) and symptoms score of traditional Chinese medicine (TCM) before and after treatment, and at the 1-month follow-up. The therapeutic efficacy was assessed at the 1-month follow-up. Results: The KWST grading and FILS result after treatment and at the follow-up were significantly different from those before treatment in both groups (all P<0.001); the results of these two items at the follow-up were not significantly different from those after treatment in the two groups (all P>0.05). There were significant differences in the KWST grading and FILS result between the two groups after treatment and at the follow-up (all P<0.05). The TCM symptoms score changed significantly after treatment and at the follow-up compared with that before treatment in both groups (all P<0.001). The TCM symptoms grading efficacy at the follow-up was significantly different from that after treatment in the observation group (P<0.05), while the difference was statistically insignificant in the rehabilitation group (P>0.05). The TCM symptoms grading efficacy in the observation group was significantly different from that in the rehabilitation group after treatment and at the follow-up (both P<0.05). Conclusion: Based on the conventional treatment for stroke, acupuncture plus rehabilitation training or use of rehabilitation training alone both can improve the clinical symptoms in post-stroke deglutition disorders of qi-deficiency blood stasis pattern, but acupuncture plus rehabilitation training can produce more significant efficacy and better long-term efficacy in improving TCM symptoms.

Objective To observe the changes of islet cell apoptosis and oxidation-antioxidation before the transplantation, and to explore the pathways of islet protection. Methods Fifteen human pancreases were perfused with the Hanks solution containing collagenase, then digested and isolated. During the procedure, islet cell apoptosis was detected by TUNEL, SOD and MDA in the pancreas were measured by colorimetric method, and the morphologic changes were observed by H-E staining and dithizone staining. Results In the procedure of human islet isolation, especially in the stage of digestion, the apoptosis of human islet cells occurred. In the stages of perfusion and digestion, the MDA contents reached the high levels (6. 18 ± 2. 38 and 9. 21 ± 2. 75 umol/mg protein respectively),and the structures of the islets and tissues around the islets were damaged. Conclusion In the stages of perfusion and digestion, apoptosis of islet cells can be caused by oxidation. It suggests that antioxidation is a pathway for protection of islets before transplantation.

After 28 foreign species of AM fungi were inoculated in sterilized soil, the effects of the AM mycorrhizal colonization and the medicine quality of Paris polyphylla var. yunnanensis were observed by combination of inoculation test in pot at room temperature and instrumental analysis. The results showed that, compared with control group (CK), the inoculation of foreign AM fungi in the soil influenced the spore density, mycorrhizal infection rate, and colonization intensity of AM fungi in root system of P. polyphylla var. yunnanensis. The inoculation of foreign AM fungi enhanced the mycorrhiza viability of P. polyphylla var. yunnanensis by increasing the activity of succinic dehydrogenase (SDH) and alkaline phosphatase (ALP) in intraradical hyphae. The content of single steroid saponin in rhizome of P. polyphylla var. yunnanensis showed variation after P. polyphylla var. yunnanensis was inoculated by different foreign species of AM fungi, which was beneficial for increasing the medicine quality; however, the kinds of steroid saponin showed no difference. In a degree, there was a selectivity of symbiosis between P. polyphylla var. yunnanensis and foreign AM fungi. And we found that the Claroideoglomus claroideum and Racocetra coralloidea were best foreign AM fungi species for cultivating P. polyphylla var. yunnanensis under field condition.

The present study is to establish Caco-2/HT29-MTX co-cultured cells and investigate the transport capability of PLGA nanoparticles with different surface chemical properties across Caco-2/HT29-MTX co-cultured cells. PLGA-NPs, mPEG-PLGA-NPs and chitosan coated PLGA-NPs were prepared by nanoprecipitation method using poly(lactic-co-glycolic acid) as carrier material with surface modified by methoxy poly(ethylene glycol) and chitosan. The particle size and zeta potential of nanoparticles were measured by dynamic light scattering. Coumarin 6 was used as a fluorescent marker in the transport of nanoparticles investigated by confocal laser scanning microscopy. The transport of furanodiene (FDE) loaded nanoparticles was quantitively determined by high performance liquid chromatography. Colchicine and nocodazole were used in the transport study to explore the involved endocytosis mechanisms of nanoparticles. Distribution of the tight junction proteins ZO-1 was also analyzed by immunofluorescence staining. The results showed that the nanoparticles dispersed uniformly. The zeta potential of PLGA-NPs was negative, the mPEG-PLGA-NPs was close to neutral and the CS-PLGA-NPs was positive. The entrapment efficiency of FDE in all nanoparticles was higher than 75%. The transport capability of mPEG-PLGA-NPs across Caco-2/HT29-MTX co-cultured cells was higher than that of PLGA-NPs and CS-PLGA-NPs. Colchicine and nocodazole could significantly decrease the transport amount of nanoparticles. mPEG-PLGA-NPs could obviously reduce the distribution of ZO-1 protein than PLGA-NPs and CS-PLGA-NPs. The transport mechanism of PLGA-NPs and mPEG-PLGA-NPs were indicated to be a combination of endocytosis and paracellular way, while CS-PLGA-NPs mainly relied on the endocytosis way. PEG coating could shield the surface charge and enhance the hydrophilicity of PLGA nanoparticles, which leads mPEG-PLGA-NPs to possess higher anti-adhesion activity. As a result, mPEG-PLGA-NPs could penetrate the mucus layer rapidly and transport across Caco-2/HT29-MTX co-cultured cells.
