ObjectiveTo compare the therapeutic efficacies and adverse reactions of micro-invasive thread embedding with two types of materials in treating chronic facial paralysis.MethodTotally 186 patients with chronic facial paralysis were randomized into a catgut group and a PDS group, 93 cases in each group. For the two groups, Cuanzhu (BL2), Yuyao (EX-HN4), Taiyang (EX-HN5), Dicang (ST4), Jiache (ST6), Quanliao (SI18), Yingxiang (LI20), Qianzheng (Extra), Xiaguan (ST7), Fengchi(GB20), and bilateral Hegu (LI4) and Zusanli (ST36) were selected. The thread embedding treatment was given once every 10 d, 3 timesas a treatment course, successively for 2 courses. The therapeutic efficacy and adverse reactions were analyzed after 2 treatment courses. ResultThe Sunnybrook Facial Grading System scores were significantly increased after intervention in the two groups (P<0.05), while there was no significant difference in comparing the therapeutic efficacy between the two groups (P>0.05). There were no significant differences in comparing the adverse reactions including tenderness, nodules, and swelling right after thread embedding between the two types of materials (P>0.05); 10 d after thread embedding, the adverse reactions happened inthe catgut group were significantly more than that in the PDS group (P<0.05); 30 d after thread embedding treatment, the tenderness occurred more frequently in the catgut group compared to that in the PDS group; although the occurred frequency of nodules and swelling was comparatively low, the total frequency in the catgut group was significantly higher than that in the PDS group (P<0.01). There were no significant differences in comparing the adverse reactions between the two groups 60 d after treatment (P>0.05).Conclusion Acupoint thread embedding with PDS can help recover facial nerve function in chronic facial paralysis; as a thread embedding material, PDS thread produces a lower occurrence rate of adverse reactions, and thus it’s a kind excellent thread embedding material.

OBJECTIVETo compare the clinical therapeutic effects on intractable facial paralysis among acupuncture, acupoint catgut embedding and PDS embedding.

METHODSTwo hundred and seventy-nine patients of intractable facial paralysis were randomized into an acupuncture group, a catgut embedding group and a PDS embedding group, 93 cases in each one. Cuanzhu (BL 2), Yuyao (EX-HN 4), Taiyang (EX-HN 5), Xuanlu (GB 5), Dicang (ST 4), Jiache (ST 6), Quanliao (SI 18), Qianzheng (Extra), Xiaguan (ST 7) and Fengchi (GB 20) on the affected side and bilateral Hegu (LI 4) and Zusanli (ST 36) were selected in the three groups. In the acupuncture group, acupuncture was applied to those acupoints, once every two days; 10 treatments made one session; the successive three sessions were required. In the catgut embedding group and the PDS embedding group, catgut and PDS were embedded separately, once every 10 days; 3 treatments made one session and the successive two sessions were required. The therapeutic cycle was 2 months in the three groups. The therapeutic results were analyzed statistically 2 months later. The scores of Sunnybrook facial nerve grading system and the facial nerve electroneurography (ENoG) were used for the efficacy assessment before and after treatment in the three groups.

RESULTSAfter treatment, the score of Sunnybrook facial nerve grading system was improved apparently after treatment as compared with that before treatment in any of the three groups (all P < 0.05). The score in either of the embedding groups was better than that in the acupuncture group (both P < 0.05). The difference was not significant between the catgut embedding group and the PDS embedding group (P > 0.05). After treatment, ENoG wave ampli tude values in the frontal muscle and orbicularisoris muscle on the affected side were improved as compared with those before treatment in the three groups (all P < 0.05). Those in the catgut embedding group and the PDS embedding group were better than those in the acupuncture group (all P < 0.05), and had no significant difference as compared with those on the healthy side (P > 0.05). In the acupuncture group, ENoG wave amplitudes on the affected side were lower than those on the healthy side (both P < 0.05).

CONCLUSIONAcupuncture, catgut embedding and PDS embedding at acupoints all achieve the therapeutic effects on intractable facial paralysis. However, the acupoint embedding therapy presents more advantages on the recovery of facial nerve function. The efficacy is similar between the catgut embedding and the PDS embedding.

MicroRNAs (miRNAs) are a class of small non-coding RNAs, which mainly regulate gene expression through post-transcriptional process. They are highly conserved, tissue-specific and highly specific in miRNA-binding on 3'-untranslated regions. MicroRNAs have been identified as crucial regulators in myocardial cell proliferation, differentiation and apoptosis, migration of cardiac neural crest cells, cardiac morphogenesis and cardiac patterning processes, which may provide a new insight into the research on developmental mechanism of congenital heart diseases. The research on miRNAs in congenital heart diseases includes clinical research and animal experiments. This article reviews two types of research advances, the mechanism of congenital heart diseases, and the current status and limitation of the domestic reports.

OBJECTIVEIn this study, five heavy metals contamination of soil and different parts of Panax notoginseng in the plantation area was investigated. Analysis of heavy metals correlation between the planting soil and P. notoginseng; and the absorption and accumulation characteristics and translocation of soil heavy metals by P. notoginseng plants was revealed.

METHODThrough field investigation and laboratory analytical methods, analysis of China's 30 different soil P. notoginseng origin and content of heavy metals in five different parts of the P. notoginseng plant content of heavy metals.

RESULTThe results revealed that the soil heavy metals should not be neglected in the plantation area Referring to the national soil quality standards (GB15608-1995), the excessive degree of soil heavy metals pollution showed Hg > As > Cd > Cr in the plantation area, and Pb content of soil was in the scope of the standard. Refer to 'Green Industry Standards for Import and Export of Medical Plants and Preparations', the excessive degree of heavy metals content of P. notoginseng plants showed As > Pb > Cr > Cd, and Hg content of plants was in the scope of the standard. Concentrations of five heavy metals of underground parts of P. notoginseng plants are higher than aboveground, and heavy metals elements are more concentrated in the root, followed by the rhizome of P. notoginseng plants. Heavy metal accumulation characteristics of the different parts of the P. notoginseng of the overall performance is the root > the rhizome > the root tuber > leaves > stems. From the point of view BCF value analysis of various parts of the P. notoginseng plants to absorb heavy metals in soil, BCF values of all samples were less than 1, description P. notoginseng not belong Hyperaccumulator. From the view of transportation and related analysis of the soil-P. notoginseng systems, the rhizome of P. notoginseng and the content of As and Cr in soil was significantly correlated, the root of P. notoginseng and the content of Cd in soil was significantly correlated, and no significant correlation between the other indicators. Through the analysis of transportation transfer coefficient showed: Pb, As and Cr are not easy to transport aboveground part from the underground, but Cd and Hg are relatively easy to transport stems from rhizome, the migration of five heavy metals in the aerial part is relatively strong, and heavy metal of stems is easily transported to the leaves.

CONCLUSIONP. notoginseng does not belong to the enrichment of heavy metals in crops, especially for Hg in soil with strong patience. In survey area, the content of heavy metals of P. notoginseng's planting soil is relatively high, and the heavy metals As, Pb, Cr, Cd of P. notoginseng also exist heavy metals exceeded problems. Due to the presence of heavy metals in crops internal absorption and translocation of special laws, accumulation of heavy metals varied significantly in different parts of P. notoginseng. The overall, the performance for the heavy metal content of the underground parts is more than aboveground, it explain heavy metals of P. notoginseng plants is still the main source of the soiL Therefore, the key to control of planting area soil environmental quality and reduce exogenous harmful substances secondary pollution of soil in the cultivation process are to study and solve the heavy metals pollution problem of P. notoginseng.
