Objective To investigate effects of co-grafts of bone marrow stromal cells (BMSCs) combined with nerve growth factor (NGF) suspension on repair of spinal cord injury (SCI) in adult rats so as to determine whether the co-grafts are more effective than a single protocol.Methods Spinal cords of adult rats (n=32) were injured by the modified Allen's method.One week after injury,the injured cords were injected with Dubecco-modified Eagles Medium,BMSCs,NGF,and BMSCs plus NGF respectively.One month and two months after injury,rats were respectively sacrificed-and their injured cord tissues were sectioned to identify the transplanted cells under fluorescent microscopy.We observed axonal regeneration and differentiation of BMSCs through immunocytochemical staining conducted with neurofilament (NF) and Neuron-Specific Nuclear Protein (NeuN) and glial fibrillary acidic protein (GFAP).We measured the cavity volume by staining with hematoxylin-eosin (HE).At the same time,rats were subjected to behavioral tests using the open-field BBB (blood brain battier) scoring system.Results One month and two months after transplantation,immunocytochemical staining showed that transplanted cells partially expressed NeuN and GFAP.At the same time,significant reduction in lesion area (P＜0.05) and improvement in BBB lo- comotor rating scale (P＜0.05) were observed in the cases that received implantation,as compared with those that received vehicle injection.More importantly,further reduction in lesion area and improvement in function were ob- served in the combined treatment group.Conclusions BMSCs can differentiate into neurons and astroeytes. BMSCs and NGF can reduce lesion size,promote axonal regeneration and improve functional recovery,and may have a synergistic effect.

To study the impact of five different origin processing methods, namely natural drying, drying in baking shop, drying by microwave heating, drying in drum and drying with sulphur fumigation, on the quality of Lonicerae Japonicae Flos from Donghai cultivation base in Jiangsu Province, with the contents of chlorogenic acid and galuteolin and the similarity in HPLC fingerprints as the evaluation indicators. The results showed that different origin processing methods had significant impact on the content of chlorogenic acid and the similarity in HPLC fingerprints, but with no significant difference on the content of galuteolin. By means of drying by microwave heating and drying in drum, the samples showed higher contents of chlorogenic acid, respectively 3.67% and 3.39%. The similarities of HPLC fingerprints were 0.815 and 0.793, respectively. By means of the drying in baking shop and the drying with sulphur fumigation, the contents of chlorogenic acid in the samples were 2. 87% and 2. 53% , respectively. The similarities of HPLC fingerprints were 0.964 and 0.765, respectively. The lowest content of chlorogenic acid in naturally dried samples was 1.92%. The similarity of HPLC fingerprints was 0.940. According to the findings as well as the internal control standards for Lonicerae Japonicae Flos herbs of Jiangsu Kanion Pharmaceutical Co. , Ltd. , the optimum processing method for Lonicerae Japonicae Flos from Donghai cultivation base was the drying in baking shop. This study provided a theoretical basis for determining the processing method for Lonicerae Japonicae Flos from Donghai cultivation base of Jiangsu Province.

OBJECTIVEHighland natives adapt well to the hypoxic environment at high altitude (HA). Several genes have been reported to be linked to HA adaptation. Previous studies showed that the endothelial ni- tric oxide synthase (ENOS) G894T polymorphism contributed to the physiology and pathophysiology of hu- mans at HA by regulating the production of NO. In this meta-analysis, we evaluate the association between the ENOS G894T polymorphism and HA adaptation through analyzing the published data.

METHODSWe searched all relevant literature about the ENOS G894T polymorphism and HA adaptation in PubMed, Med- line, and Embase before Step 2015. A random-effects model was applied (Revman 5.0), and study quality was assessed in duplicate. Six studies with 634 HA native cases and 621 low-altitude controls were included in this meta-analysis.

RESULTSFrom the results, we observed that the wild-type allele G was significantly overrepresented in the HA groups (OR = 1.85; 95% Cl, 1.47-2.33; P < 0.0001). In addition, the GG genotype was significantly associated with HA adaptation (OR = 1.99; 95% Cl, 1.54-2.57; P < 0.0001).

CONCLUSIONOur results showed that in 894 G allele carriers, the GG genotype might be a beneficial factor for HA adaptation through enhancing the level of NO. However, more studies were needed to confirm our findings due to the limited sample size.

Objective To explore the relationship between adjustment of immunosuppressant and prognosis in renal transplantation recipients with pulmonary infection. Methods The clinical data of 98 patients with pulmonary infection following renal transplantation were retrospectively analyzed.Patients were divided into two groups: conventional group (n = 45) and immunosuppressant adjustment group (n = 53). The mortality, recovery time and rejection rate in two groups were analyzed under the statement of serious infection (SOFA≥12) and slight infection (SOFA＜ 12) by sequential organ failure assessment (SOFA) score. Results When the SOFA scores ≥ 12, the mortality and recovery time in immunosuppressant adjustment group were significantly lower than in conventional group (P＜0.05), but there was no significant difference in the rejection rate between two groups (P＞0.05). When the SOFA scores ＜11, there was no significant difference in mortality and recovery time between the two groups (P＞0.05). The incidence of rejection in immunosuppressant adjustment group was significantly higher than in conventional group (P＜0.05).Conclusion Mortality could be decreased and course of anti-infection treatment could also be shortened by adjusting the immunosuppressant in renal transplantation recipients with serious pulmonary infection (SOFA≥12). Immunosuppressant agent was proposed to maintain the original treatment protocol when the infection was slight (SOFA＜12).
