The endophytic microorganisms found widely in many kinds of plants mediate various effects to theirs hosts. In this study, seven different dominant endophytes (SDE01 to 07) isolated from a Hy-peraccumulator-Solanum nigrum L. were resistant to Cd2+, and the strain SDE06 survived even in the medium containing 80 mg/L of Cd2+. Bacteria strain SDE06 was identified as Bacillus sp.. The removal of Cd2+ of SDE06 in different conditions were studied. Under the optimal conditions, the incubating time was 36 h, the solution pH 6.0, the temperature was 37?C and the Cd2+ concentration of medium was 20 mg/L, the highest removal rate was up to 80.2% at this condition.

With references of historical materials and modern literature regarding acupoint characteristic, a secondary analysis on the concept, origin, related factors and research methods in present research of acupoint characteristic is performed. The acupoint characteristic should be considered as an acupoint inherent attribute that could explain physiological and pathological manifestations at the same time, including location attribute and function attribute, which is related with time and treatment method. Some re-thinking on acupoint characteristic is proposed as well as advice on further research method and direction, hoping to promote the research development of acupoint characteristic.

The rate of corneal graft rejection is still high for high-risk keratoplasty although immune suppression drug is routinely used.The role of traditional Chinese medicine in corneal transplantation is concerned gradually.Heijingpaichitang on the prevention and treatment of rats with high-risk corneal allograft rejection needs further study.Objective This study was to investigate the inhibitory effect of heijingpaichitang on high-risk corneal transplantation immune rejection in rats.Methods Sixteen female SD rats were used as the donors and 32female Wistar rats were served as recipients.The high-risk corneal trasplantation models were established by corneal suture in 32 Wistar rats,and then homogeneity variant SD-Wistar corneal transplantation was performed.The recipients were randomized into model control group,cyclosporinc A (CsA)group,heijingpaichitang group and CsA +heijingpaichitang group.CsA,heijingpaichitang and CsA + heijingpaichitang was orally administered 4 days after operation once per day for 15 days,and normal saline solution was used at the same way in the model control group.Ocular anterior segment reaction was examined under the slit lamp and corneal opacification,edema and neovasculation were scored based on Larkin' s criteria.Rejection index of the corneal graft was recorded and the graft survival time was calculated.The pathological examination of the corneal graft was carried out in all rats,and the inflammatory cells in the corneas and CD4+ cells in the periphery blood were assayed using flow cytometry.The use of the animals complied with ARVO Statement.Results Corneal graft rejection occurred in 10 days after operation in the model control group,12-13 days in the CsA group and heijingpaichitang group and 22 days in the CsA +heijingpaichitang group.Compared with model control group,the scores of the corneal opacification,corneal edema and neovascularization were significantly lower in the CsA group,heijingpaichitang group and CsA+heijingpaichitang group (P＜0.05),and all the scores were declined in the CsA+ heijingpaichitang group compared with CsA group and heijingpaichitang group(P＜0.01),but no significant differences were seen in the scores between the CsA group and heijingpaichitang group(P＞0.05).The mean survival time of grafts was (10.38 ±1.69)days in the model control group,(22.50 ± 3.07) days in the CsA + heijingpaichitang group,with the significant difference (t =-9.790,P =0.000).The pathological examination of graft showed that the lymphocytes and new blood vessels were less in the CsA+heijingpaichitang group compared with CsA group and heijingpaichitang group 15 days after operation.Flow cytometry verified that the number of lymphocytes in graft,CD4+cells and CD4+/CD8+ in periphery blood were significantly lower in the heijingpaichitang group,CsA group and CsA+heijingpaichitang group compared with model control group (P＜0.05).Conclusions Heijingpaichitang can inhibit immune rejection to certain extent in high-risk corneal transplantation rat and has a similar effect to 0.1％ CsA.Heijingpaichitang and 0.1％ CsA have a synergistic effect.

OBJECTIVETo explore the relationship between maternal milk and serum thyroid hormones in patients with thyroid-related diseases.

METHODSSerum and breast milk samples were collected from 56 breastfeeding mothers. Milk and serum free triiodothyronine (FT3), free thyroxine (FT4), triiodothyronine(T3), thyroxine (T4), and thyrotrophin (TSH) were determined, and T3/T4 was calculated. Using the serum thyroid hormones as the independent variables and milk thyroid hormones as the dependent variables, we performed linear regression analysis.

RESULTSThe milk FT3, FT4, T3, T4, TSH, and T3/T4 were (2.30 ± 0.82) pg/ml ,(0.45 ± 0.26) ng/dl, (0.35 ± 0.20) ng/ml, (2.96 ± 1.55) Μg/dl, (0.12 ± 0.08) ΜU/ml, and 0.12 ± 0.04, respectively. Milk FT3 (r = 0.778, P = 0.000), T3 (r = 0.603, P = 0.000), T4 (r = 0.485, P = 0.004), and TSH (r = 0.605, P = 0.000) concentrations were positively correlated with those in serum.

CONCLUSIONThyroid hormones are present in human milk and are positively correlated with those in serum.

Background Human limbal allograft transplantation or limbal autograft transplantation are the primary approaches to the severe corneal-blindness,but their application in clinic were limited because of the defects of donor material.With the development of tissue engineering technology,transplantation of in vitro cultured limbal epithelial stem cells is being an advanced management.Objective The aim of this work was to expand human limbal epithelial stem cells ex vivo under the guidance of confocal microscope and to lay the foundation for fabricating ex vivo cultured cell sheets.Methods Ten eyes of ten patients were examined with the Heidelberg Retina Tomography Ⅲ Rostock Cornea Module(HRT3-RCM)to elucidate the structure of the human corneoscleral limbus and to correlate limbal epithelial dimensions.According to the analysis of the images of limbal epithelia,the limbal tissues provided by Eye Bank of Henan Eye Institute were cut into suitable explants.Then,this study was conducted to expand limbal epithelial stem cells ex vivo on denuded amniotic membrane.The phenotypes of primary cultured cells were evaluated by morphology and immunofluorescent staining with antibodies for limbal epithelial stem cell markers (p63,cytokeratinl9)and differentiation markers(keratin 3,involucrin).This experimental procedure was approved by the Ethic Committee of Henan Provincial People's Hospital.The written informed consent was obtained from subjects before initiation of any examination.Results The palisade morphology of human limbus was imaged clearly on the laser scanning in vivo confocal microscopy and many hyperreflective cells were observed in palisade basal cells.The cell-island phenomenon was seen in the basement membrane under the laser scanning in vivo confocal microscopy.The oblique sections of limbus showed many papilla-like epithelial columns below the superficial limbal epithelia.Throughout the experiment duration,the epithelial cells grew well with the migration rates from limbal tissue (68.62± 16.94)％ and the migration time(5.83 ±2.04)days,which depended on the tissue freshness.Compared with the second and forth batch of tissue,the migration rates of the third and sixth batch of tissues were significantly higher(P＜0.05),and the migration time was evidently longer in the forth and sixth batch of tissue compared with the first,second,third and fifth batch(P＜0.05).The positively expressing rates in the cultured corneal stem cells were 4.05％ and 36.52％ for p63,26.07％ and 40.55％ for CK19,57.88％ and 40.81％ for K3,64.66％ and 59.19％ for involucrin.Conclusion Human limbal epithelial stem cells can be successfully and purposefully obtained from the limbal tissue based on the guidance confocal miscroscope.The cultured corneal stem cells can grow well on the denuded amniotic membrane

OBJECTIVE: To investigate the effect of pre-amputation pain block on the N-methyl-D-aspartate receptor activation in the central nervous system of amputated rats, and the association between pre-amputation pain block and chronic amputation-related pain. METHODS: Thirty-six adult male SD rats were randomly assigned to an NA group (n=12), a PA group (n=12) and a PAB group (n=12). Group NA was intraplantarly injected saline l00 μL while group PA and group PAB were intraplantarly injected complete Freund adjuvant (CFA) 100 μL. The sciatic nerve of group NA and group PA were freed from surrounding tissue, and that of group PAB was blocked by bupivacaine under pentobarbital sodium anesthesia 5 days after the injection. Thermal withdrawal latency (TWL) was measured before and after the injection. All rats were amputated at the scheduled survival time. The expression of N-methyl-D-aspartate receptor (NR2B) was measured by immunohistochemistry in L4-6 of the spinal cord and the anterior cingulated cortex 7 days after the amputation procedure. RESULTS: The TWL after intraplantar administration of CFA in group PA and group PAB decreased significantly compared with the baseline value (P<0.05), while the saline treated control group remained unchanged. Besides the basic value, the TWL of group PA was shorter than that of group NA at the above-mentioned time-points (P<0.05). Compared with the basic value and group NA, the TWL of group PAB after the block increased significantly (P<0.05). Compared with group NA and group PAB, group PA had a remarkably high expression of NR2B (P<0.05), while there was no difference between group PA and group PAB. CONCLUSION Pre-amputation pain may activate N-methyl-D-aspartate receptor of the central nervous system, which may lead acute postoperative pain to chronic pain. It is necessary to treat pre-amputation pain.

Objective: To study the nursing of patients with morbid obesity treated with laparoscopic vertical banded gastroplasty (LVBG). Methods: Before operation, obese degree, obesity-related conditions and mental states were examined routinely. Monitoring of respiratory tract, observing operative complications and instructing of diets were done after operation. Results: Among 6 patients, 5 were at the third degree of obese, one was at second. In obesity-related conditions, 4 patients had hypertension and acantha derma, 1 had arthritis, and all had respiratory sleeping syndrome. The operations were all successful. The food amount food and body weight both decreased significantly 1 month after operation. The common operative complications were mild bleeding (1 case), shoulder-back pain (1 case), nausea and vomiting (5 cases). Diet principle was high protein, low energy, liquid food was the first choice. Conclusion: Observing and preventing respiratory sleeping syndrome are the main points of postoperative cares. Instructing patients to establish correct diet habit is the key to reach the best efficacy of LVBG.

At present, the modernization of Chinese medicine preparations (CMPs) is still a challenging task. The 3 typical Chinese medicine materials (CMMs) used for preparing CMPs are the powders, extracts, and components of Chinese medicine and their properties of CMMs are important for designing CMPs. Basing on our long term research, we have established a property system for CMMs according to the state of CMMs under an exactly condition and according to the interaction characteristics between substances. The property system could be divided into 5 categories: material composition, spatial structure, body property, surface property, physicochemical properties, and they could also be divided into 18 subcategories. Furthermore, we also established the corresponding index and characterization system, where the 61 indexes and characterization techniques were systematically summarized. At last, we hope that the article will promote the modernization of CMPs.
