Objective To analyze and explore the value of 3 T high resolution magnetic resonance vessel wall imaging for identifying the activity of Takayasu arteritis. Methods Twenty-six consecutive patients with Takayasu arteritis underwent 3.0 T high resolution MR vessel wall imaging on supraortic vessels (according to the classification of Lupi-Herrea , type Ⅰ and Ⅲ were included). Sixteen patients were in active phase and 10 in inactive phase based on the Kerr criteria. The MR vessel wall imaging appearances of Takayasu arteritis were compared between the active phase and inactive phase cases. Results Wall thickening was demonstrated in all involved arteries. There were statistically significant differences between active phase and inactive phase cases in MR appearances including multi-ring thickening of vessel wall (75/80 and 18/50), arterial inner wail enhancement (50/80 and 19/50), obscurity of perivascular fat (55/80 and 18/50,X<'2>=50.39,7.41,13.40,P<0.01). There was also a statistically significant difference in the thickness of carotid artery wall between the two groups [ (3.8±0.2) mm vs (2.5±0.8) mm]. Conclusion 3 T high resolution MR vessel wall imaging is valuable for identifying the activity of Takayasu arteritis.

Objective:To evaluate the indications, surgical skills and clinic outcomes of abdominal minimal incision sacrocolpopexy (AMISC) for treatment of advanced pelvic organ prolapse (POP).Methods:The retrospective study analyzed 30 women with advanced POP who underwent AMISC between June 2016 and October 2019, including 9 cases of recurrent prolapse and 10 cases of vault prolapse. AMISC was especially applicable to: (1) patients with several medical complications who was unable to tolerate general anesthesia or laparoscopic surgery, but able to tolerate combined spinal-epidural anesthesia and open surgery; (2) other abdominal procedures were indicated to perform with AMISC simultaneously, such as myomectomy, subtotal hysterectomy etc, the specimens were easy to get out of the abdominal cavity and morcellation was avoided; (3) surgeons preferring open surgery to laparoscopic surgery or skilled in open surgery; (4) patients with prior pelvic operations, presenting severe abdominal and pelvic adhesions. Objective outcomes were assessed by pelvic organ prolapse quantification (POP-Q) system. Subjective outcome were assessed by pelvic floor distress inventory-short form 20 (PFDI-20), pelvic floor impact questionnaire-short form (PFIQ-7) and patient global impression of improvement (PGI-I).Results:All patients with 1-3 medical complications were successfully performed with AMISC without stopping procedure, enlarging the incision or changing to other procedure, the operation duration was (110±19) minutes. The mean time of follow-up was (33.5±12.4) months (range: 8-49 months). The postoperative points of Aa, Ba, C, Ap, Bp reduced significantly and point C improved from (2.33±2.50) cm to (-7.54±1.18) cm after AMISC ( P<0.01). The objective cure rates were both 100% (30/30) in apex and posterior compartment, while 97% (29/30) in anterior compartment. Postoperative scores of PFDI-20 and PFIQ-7 were all significant decreased (all P<0.01). About PGI-I, 29 patients chose “significant improvement”, subjective satisfaction was 97% (29/30). Anterior sacral plexus hemorrhage occurred in 2 cases (7%, 2/30). There was no intestinal obstruction or injury of bladder, bowel and ureter intra- and postoperation. Two cases (7%, 2/30) had mesh exposure. Conclusion:AMISC is a safety, convenient, minimal traumatic and durable procedure for apical prolapse with short learning curve in the most of cases.

Objective To explore the effects of nursing intervention in the clinical emergency of organic phosphorus pesticide poisoning. Methods Fifty-six patients with organic phosphorus pesticide poisoning, who were admitted to the Department of Emergency in the Affiliated Hospital of Zhejiang Normal University from May 2012 to May 2013, were selected. They were assigned into observation group and received nursing intervention on the basis of regular nursing care. 56 patients with organic phosphorus pesticide poisoning, who were admitted to the same hospital from April 2011 to April 2012 and received only regular emergency nursing care, were selected as control group. Volume of gastric lavage, duration of gastric lavage, number of cases with overflow of gastric contents during a surgery, and complications were collected in the two groups. The satisfaction rates of patients and their families from the two groups were also sur-veyed after the nursing care. Results The volume of gastric lavage, duration of gastric lavage, cases with overflow of gastric contents during a surgery and the incidence of complications in observation group were all less than those in control group. The satisfaction rate in observation group was 96.4%, in which 28 patients were very satisfied, 26 fairly satisfied, 2 unsatisfied. The satisfaction rate in control group was 75.0%, in which 20 patients were very satisfied, 22 fairly satisfied, 14 unsatisfied. The difference of satisfaction rates between the two groups was statistically significant (P<0.05). Conclusion Strengthening of diet and mental nursing for emergency patients with severe organic phosphorus pesticide poisoning helps safeguard patients ’ life at the meantime, wins high recognition.

Objective: To observe the changes of Notch signaling pathway related molecule expression in hippocampus of rats with stagnation of liver qi and spleen deficiency syndrome and to explore the regulatory effect of Xiaoyaosan. Methods: Male SD rats were randomly divided into four groups: normal group, model group, model+xiayaosan group and model+fluoxetine group, each group had 12 rats. The stagnation of liver qi and spleen deficiency model was established by chronic immobilization stress for 21 days. Detection of Nissl bodies by Nissl staining, expression of NICD, Hes1, Hes5 and Jad1 were detected by Fluorescent quantitative PCR and Western-blot method. Results: Compared with the normal group, the number of Nissl bodies in the model group decreased significantly (P ＜ 0.01), which showed that Xiaoyaosan and fluoxetine could reverse it (P ＜ 0.01). The expression of Notch signaling pathway-related protein in model group was significantly lower than that in normal group (P ＜ 0.01), which showed that Xiaoyaosan and fluoxetine could reverse the expression of NICD, Hes5 and Jag1 protein (P ＜ 0.05, P ＜ 0.01). Compared with the normal group, the expression of each gene in the model group decreased (P ＜ 0.01), which showed that Xiaoyaosan and fluoxetine could reverse the expression of NICD, Hes1 and Hes5 mRNA (P ＜ 0.05, P ＜ 0.01). Conclusion: The hippocampal neurons of rats with stagnation of liver qi and spleen deficiency syndrome were damaged and the Nissl bodies were reduced, the expression of each protein and gene in Notch signaling pathway decreased. Xiaoyaosan may play a therapeutic role by regulating the expression level of hippocampal related molecules to protect neurons.

To investigate the effect of hSCGF-alpha on human Umbilical Cord Mesenchymal Stem Cells (hUCMSCs), we obtained hSCGF-alpha using genetic engineering, hSCGF-alpha gene was amplified from hUCMSCs cDNA using two-step PCR and was inserted into pET-28a(+) plasmid vector. Induced by IPTG at 20 degrees Celsius for 24 h, the fusion protein expressed in E. coli BL21 (DE3) was mainly existing in soluble form. The recombinant hSCGF-a was purified using NI-NTA affinity chromatography and the purity was up to 90%. The colony forming test revealed that combined use hSCGF-alpha and rmGM-CSF (recombinant murine GM-colony stimulating factor, rmGM-CSF) had granulocyte/macrophage (GM) promoting effects on murine bone marrow GM progenitor. In addition, the results indicated that hSCGF-alpha and rhGM-CSF had stimulatory effect on hUCMSCs and their synergetic effect was the strongest.

Major depressive disorder (MDD) is a common affective disorder.With its unique characteristics and advantages,traditional Chinese medicine (TCM) has played an important role in the treatment of MDD.Recent researches have revealed that the neuroinflammation-induced neurogenesis reduction were the key pathology of MDD.This analysis indicated that salvia was frequently used for treatment of MDD from the prescriptions reported in literatures.Salvianolic acid (SalB),one of main active compounds of salvia,had showed anti-inflammation and neuroprotection effects in previous studies.In this review,we summarized the antidepressant effects of SalB through regulating microglial activation,inhibiting neuroinflammation and promoting neurogenesis.According to the theory of removing blood stasis for promoting tissue regeneration,it was suggested that the novel antidepressant strategies for antiinflammatory and neuroprotective activities were through microglia-modulating pathway with TCM.

OBJECTIVE: To explore the repair effects of bone marrow mesenchymal stem cells( BMSCs) on hematopoietic injury induced by benzene poisoning in mice. METHODS: Five specific pathogen free healthy male Kunming mice were selected to obtain BMSCs through bone marrow attachment culturing method. The Kunming mice were randomly divided into poisoning group and BMSCs transplantation group,18 mice in each group,after the benzene poisoning model was established by subcutaneous multi-point injection of benzene and oil mixture 3 times/week,10 weeks continuously. Each group was injected through tail vein with 250. 0 μL 0. 9% sodium chloride solution or 250. 0 μL BMSCs suspension( cell density 2 × 109/L) once per week for 4 weeks,respectively. The control group( 10 mice) was not given any treatment.Mice were euthanized 2 weeks after treatment. The blood routine examination was conducted. Nucleated cells in bone marrow were observed after Giemsa staining. The clones of hemopoietic progenitor cells were counted and the levels of serum interferon-γ( IFN-γ) were examined using enzyme-linked immune sorbent assay. RESULTS: The mouse model of chronic benzene poisoning was established successfully. After the BMSCs transplantation treatment,the white blood cell count,platelet count,red blood cell count,hemoglobin level and bone marrow nucleated cell as well as granulocyte-macrophage colony forming unit( CFU-GM) in benzene poisoning group were significantly decreased compared with control group( P <0. 01),while those indexes of BMSCs treatment group were higher than that of benzene poisoning group( P < 0. 05). The counts of platelet,red blood cell,bone marrow nucleated cell and CFU-GM in BMSCs treatment group were significantly lower than that of control group( P < 0. 05). The level of serum IFN-γ in benzene poisoning group was higher than that of control group( P < 0. 01),and serum IFN-γ level in BMSCs treatment group was lower than that of benzene poisoning group( P < 0. 01). There was no significant difference of IFN-γ level in BMSCs treatment group compared with control group( P > 0. 05). CONCLUSION: BMSCs have repair effects on hematopoietic system injury caused by benzene poisoning.
