Objective To observe the numerical characteristics of dendritic cells (DC),the DC subsets(myeloid dendritic cell,MDC; plasmacytoid dendritic cell,PDC) and CD4+ CD25 + CD127low/-Tr cells in peripheral blood of Graves disease (GD) patients.Methods According to the clinical manifestations and serum FT3,FT4 and TSH,the GD patients were divided into the untreated-group,the clinical remission group and the clinical stable group,and set normal control group as well.The flow cytometry was used to detect DC and CD4+CD25+CD127low/-Tr cells of the percentage of CD4+ T cells in subjects peripheral blood(EDTA-K2 anticoagulated).The indicators were compared among various groups,and the correlation between the indicators with serum FT3,FT4 and TSH were observed.Results (1) In the untreated-group,the clinical remission group,the clinical stable group,and normal control group,total DCs,MDCs and MDC/PDC gradually declined,untreated-group has a significant difference from the other three groups also the significant difference was found among other three groups; (2) In the untreated-group,the clinical remission group,the clinical stable group,and normal control group,PDCs declined successively,but only the difference was found between untreated-group and normal control group; (3)In the untreated-group,the clinical remission group,the clinical stable group,and normal control group,CD4+CD25+CD127low/-Tr cells gradually raised,but only the difference between untreated-group and normal control group make sense; (4)In the untreated-group,PDCs and CD4+CD25+CD127low/-Tr cells have a certain relevance; (5)There was good correlation between DCs and serum FT3,FT4 and TSH,but CD4+CD25+CD127low/-Tr cells only have correlation with FT3 and FT4.Conclusion DC,MDC,MDC/PDC increased in the untreated-GD patients,and decreased after the therapy of anti-thyroid.Therefore,DCs and the DC subsets are expected to be used to monitor GD in the course of disease.CD4+CD25+CD127low/-Tr cells can be used as a new indicator of the onset of GD.

?Optic neuritis ( ON) is one of the most common causes of vision loss by neural eye diseases in youth and middle-aged. In the past, the diagnosis simply according to the risk position, which did not distinguish from the pathogenesis and clinical characteristics, can not meet the current clinical diagnosis and treatment needs. Combining with the etiology, clinical characteristics and prognosis, the latest classification of the current international diagnosis of ON are typical and atypical ON. Typical ON relates to multiple sclerosis ( MS ) or demyelinating disease of the central nervous system, it has a relatively good therapeutic effect and prognosis. Rather than, atypical ON has complex etiology, clinical manifestation, and the treatment and prognosis are also different. At present there are many international ON treatment guidelines with level I evidence-based medical evidence, but with different genetic background, geographical environment and ethnic groups, they are not been determined. China lacks of such a multicenter large sample, a wide range of research evidence. In this paper, we will summarize the progress of the diagnosis and treatment about ON, especially about the atypical ON, in order to provide some suggestions to further improve the standardization and individualization for clinical diagnosis and treatment on ON.

OBJECTIVE: Schwann cells can promote the regeneration of damaged peripheral nerves and serve as seed cells in the engineering repair of peripheral nerve tissue. The effective culture and purification of Schwann cells are the basis of clinical treatment for peripheral nerve injury. This paper summarized the literature of culture of Schwann cells in vitro in recent ten years and made a descriptive review on the research progress of Schwann cell culture and purification, in order to provide references for culture of Schwann cells in vitro. METHODS: Literature related to Schwann cell isolation, culture and purification was retrieved from PubMed, Web of Science, Medline databases, CNKI, Wanfang, VIP and other databases. The keywords included “Schwann cells; isolation; culture; purification”. All the papers obtained from the search were read, analyzed and judged, and finally 62 papers meeting the standards were included. RESULTS: The classical methods of Schwann cell culture include tissue block culture and enzyme digestion. Purification methods include mitosis resistance, immune selection, specific adhesion, pre degeneration, cold jet, differential adherent, laminin package, low serum, stimulating factor, fluorescence activated cell sorting or magnetic activated cell sorting, immunopanning, and extracorporeal shock wave treatment. CONCLUSION: Schwann cells can be cultured and purified in various ways in vitro, and each method has its advantages and disadvantages. How to obtain high-purity Schwann cells quickly and efficiently is still a challenge. Multiple methods can be combined for purification and affective factors can be controlled for Schwann cell proliferation as much as possible.

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.

Objective To investigate insulin sensitivity and beta cell function in female systemic lupus erythematosus (SLE) patients with different glucose tolerances. Methods Insulin sensitivity and beta cell function were compared between SLE patients and non-SLE subjects in the states of normal glucose tolerance (NGT), impaired glucose tolerance (IGT)and diabetes mellitus (DM) respectively.Furthermore, risk factors for insulin sensitivity and beta cell function in SLE patients were analysed by linear regression. Results In NGT state, insulin sensitivity and beta cell function of newly diagnosed SLE patients without glucocorticoids treatment were not significantly different from those of normal control group ( P ＜0. 05). Compared with newly diagnosed SLE patients without glucocorticoids treatment and normal control group, HOMA insulin resistance index (HOMA-IR) , In (HOMA-β), In (early phase insulin secretion index, EISI ) and In ( late phase insulin secretion index, LISI ) of SLE patients with glucocorticoids treatment were significantly higher( 1.91 ± 1.04 vs 0. 81 ±0. 75,0. 94 ±0. 27;5.05 ±0. 65 vs 4. 01 ±0. 63,4. 23 ±0.47;3. 14±0.81 vs 2.42 ±0.39,2.50±0.65;2.30 ±0.55 vs 1.62 ±0.57,1.56 ±0.43;P ＜0.05),while In ( Matsuda index, MI ) was significantly lower ( 4. 53 ± 0. 54 vs 5. 27 ± 0. 68,5. 18 ± 0. 38; P ＜0. 05). In IGT and DM state, HOMA-IR (2. 84 ± 1. 87 vs 1.82 ± 1.22, 3. 18 ±2. 29 vs 2. 94 ±2. 26) and In (HOMA-β) (5. 18 ±0. 93 vs 4. 06 ±0. 58, 3. 99 ± 1.04 vs 3.43 ±0. 83) were significantly higher in SLE patients with glucocorticoids treatment than those of non-SLE subjects ( P ＜ 0. 05 ) respectively. BMI and In (daily glucocorticords doses) were independent risk factors for insulin sensitivity, and age, the SLE disease activity index(SLEDAI) and In(daily glucocorticords doses) were related factors beta cell function.Conclusion In NGT, IGT and DM state,SLE female patients with glucocorticoids treatment have reduced insulin sensitivity and increased beta cell function, these changes are related to the use of glucocorticoids.

A total of 12 cases with Achilles tendon rupture were repaired by modified Kessler's methods.The sutured tendons were then strengthened with Mitek anchor system with 2 anchors inserted into the calcaneus lateral and medial to insertion of Achilles tendon and the sutures passed through the repaired tendon using Bunnel methods.The healing of skin incision,time to weight bearing,range of motion of the ankles,calcaneal pain and re-ruptures were recorded.The results were evaluated according to Amer-Lindholm criteria.All the patients were followed up with mean 17 months (range from 14 to 25 months).There were no calcaneeal pain or re-rupture cases,neither deep nor superficial wound infection or skin necrosis cases.According to Arner-Lindholm criteria for curative result,the result was excellent in 4 cases and good in 8 cases.The Mitek anchor system can be used successfully to treat Achilles tendon rupture and decrease postoperative complications.Thus,the technique is an ideal option for Achilles tendon rupture repair.

In order to investigate the hygienic characteristic of anti-immersion trousers, ten male soldiers dressed in the trousers or in camouflage trousers were subjected to exercise test and sedentary test respectively at room temperature of 17?2℃. In the test, eleven parameters such as core temperature, skin temperature, heat flow and so on were observed. The results indicated that in sedentary tests, the low limb heat flow of the subjects dressed in anti-immersion trousers was larger than that dressed in camouflage trousers; the heat insulation value of anti-immersion trousers was smaller than that of camouflage trousers; and for the other parameters, there was no evident difference between the two group. It suggested that when used on land, hygiene characteristic and effect on body heat balance of the anti-immersion trousers were similar to those of camouflage trousers.
