ObjectiveTo explore the effect of rehabilitation evaluation and treatment on Guillain-Barré syndrome.MethodsThe rehabilitation treatment was performed in 21 patients with Guillain-Barré syndrome, and the therapeutic effect was evaluated with Lindmark Assessment.ResultsThe total effective rate of all patients was 90.47% in the upper limps and wrists, 85.71% in the hands and 95.23% in the lower limps.ConclusionThe rehabilitation can improve the therapeutic effect of Guillain-Barré syndrome.

Objective To investigate the therapeutic outcomes of unilateral adrenalectomy for Cushing syndrome in patients with adrenocorticotropic hormone (ACTH) independent bilateral macronodular adrenal hyperplasia.Methods 22 patients diagnosed with Cushing syndrome caused by ACTH independent bilateral macronodular adrenal hyperplasia from January 2005 to December 2015 were retrospectively concluded.There are 17 male patients and 5 female patients with the median age of 46.5 years.All patients were presented with Cushing syndrome such as moon face, buffalo hump and other typical symptoms of Cushing syndrome.The laboratory tests showed disappearance of cortisol rhythm, elevated 24-hour urinary free cortisol, suppressed or normal ACTH and unsuppressed low dose dexamethasone suppressing test.CT scan showed bilateral macronodular adrenal hyperplasia in all patients.Results All the patients received unilateral adrenalectomy.Pathological results showed adrenal cortex nodular hyperplasia.16 patients had reexamination in the endocrine department.The median follow-up time was 26 (17-118)months for these 16 patients.In the follow-up between 3 to 9 months after surgery, laboratory test showed serum and urinary cortisol level returned to normal range and Cushing syndrome also disappeared in these 16 patients.CT scan showed no recurrence.And no adrenal insufficiency occurred.One patient had recurrence one year after surgery and two patients turned better after surgery but had recurrence at 3 years and 10 years after surgery.Two patients received contralateral adrenalectomy and cortisol hormone replacement therapy after surgery.Another patient with recurrence refused second surgery.No recurrence was observed in other patients.Four patients were followed up by telephone, and all recovered well after surgery.18 patients had hypertension before surgery and their blood pressure significantly decreased after surgery.Among them 13 cases blood pressure returned to normal range.5 patients had elevated blood glucose before surgery, and 3 patients' blood glucose returned to normal range.Conclusions Unilateral adrenalectomy for Cushing syndrome in patients with ACTH independent bilateral macronodular adrenal hyperplasia is safe and effective.

Objective To establish a method for isolating alveolar macrophage (AM) of mouse based on flow cy tometry.Methods The lungs were digested by collagen ⅣV in vitro to prepare single-cell suspension that was stained by CD11 b and CD1 1 c antibody.CD1 1 b1owCD1 1 c + cell population were AM and isolated by flow cytometry.After that,the cell viability was measured via the Typan blue staining,and the identification of AM was through flow cytometry and real-time PCR.Results CD1 1 b1owCD1 1 c + cell population was isolated by flow cytometry,the purity was (93 ± 2)％ and the cell viability was (80 ±5)％.The real-time PCR results showed that peroxisome proliferator-activated receptor γ (PPARγ) mRNA was highly expressed in AM isolated by flow cytometry (P ＜ 0.001).In addition,the functional assay showed that the isolated AM possess high phagocytic activity.Thus,the results described above demonstrate that the isolated cells were AM.Conclusion A method for obtaining AM based on flow cytometry was established.The method has high cell purity and good cell activity which can be used for functional experiments.

OBJECTIVE To investigate the effects and mechanism of luteolin on osteogenic repair of bone defects. METHODS The targets and potential pathways of luteolin in the treatment of bone defects were screened by network pharmacology method， and then the top 2 targets were selected by Hub gene screening for molecular docking verification， with binding energy as the evaluation standard. In vitro experiments were conducted on rat bone mesenchymal stem cells （BMSC） and rat umbilical vein endothelial cells （RUVEC）. Phenotypic validation was performed using alkaline phosphatase staining， alizarin red S staining， and in vitro angiogenesis experiments. Western blot assay was used to detect the protein expressions of phosphatidylinositol 3 kinase （PI3K） and protein kinase 1 （Akt1）， so as to validate the mechanism of luteolin on osteogenic differentiation of BMSC and angiogenesis of RUVEC in vitro. RESULTS The results of network pharmacology showed that the effects of luteolin on vascular formation and bone repair in bone defects were mainly related to Akt1， SRC， estrogen receptor 1， epidermal growth factor receptor， cyclooxygenase 2， matrix metalloproteinase 9 targets， and were closely related to PI3K-Akt signaling pathway. The results of molecular docking showed that luteolin binding to Akt1 and SRC proteins was stable. The results of in vitro experiments showed that luteolin could significantly improve the expressions and activities of alkaline phosphatase in BMSC， increased the number of calcium salt deposits and calcified nodules， and promoted calcification of BMSC. Compared with luteolin 0 μmol/L group， the angiogenesis ability of RUVEC was enhanced significantly in luteolin 1， 10 μmol/L groups， the length of blood vessels and the protein expressions of PI3K and Akt1 were significantly increased （P＜0.05 or P＜0.01）； the higherthe concentration， the better the effect. CONCLUSIONS Luteolin may play a role in promoting angiogenesis and bone repair at the fracture site by activating PI3K/Akt signaling pathway and promoting the protein expressions of PI3K and Akt1.
