Objective To observe the clinical efficacy of Yu’s meridian detection and treatment plus acupuncture in treating facial paralysis.Method Sixty patients with facial paralysis in acute stage were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by Yu’s meridian detection and treatment plus acupuncture, while the control group was by ordinary acupuncture. The House-Brackmann (H-B) scale and symptom-sign scores were observed before and after the treatment.Result The H-B scale scores were changed significantly in the two groups after the treatment (P<0.05). After the treatment, the H-B score of the treatment group was significantly different from that of the control group (P<0.05). The symptom-sign scores were significantly changed in both groups after the treatment (P<0.01). The symptom-sign score of the treatment group was significantly different from that of the control group after the treatment (P<0.05).Conclusion Yu’s meridian detection and treatment plus acupuncture is an effective method in treating facial paralysis.

Aim To investigate the antioxidant capacity of crocetin and crocin in an in vivo system.Methods Column chromatography was applied to the seperation of crocetin and crocin-1 from gardenia.Crocetin(6.25,12.5 and 25.0 mg·kg~(-1)·d~(-1)) and crocin (18.7,37.5 and 75.0 mg·kg~(-1)·d~(-1)) were orally administered to kunming mice.Then,superoxide dismutase(SOD),glutathione peroxidase(GSH-Px),total antioxidant capacity(TAOC)and malondialdehyde(MDA)in mice were determined for the comparison of antioxidant activity of crocetin and crocin-1.Results Oral administration of crocetin and crocin for six weeks could enhance SOD of liver and kidney,GSH-Px of liver and TAOC of heart and kidney.In addition,it could decrease MDA of serum in mice.Conclusions The comparison of results suggests the evidence supporting the comparable antioxidant activity of crocetin and crocin.The results of the research also indicate that liver and kidney are two organs targeted for protection concerning endogenous antioxidant among various tissues.

Research on the association between maternal periodontal disease and the risk of preeclampsia has generated inconsistent results. This meta-analysis was conducted to evaluate the association between maternal periodontal disease and the risk of preeclampsia. A literature search of PubMed and Embase was performed to identify relevant papers published before March 2013. Only observational studies that assessed maternal periodontal disease and the risk of preeclampsia were selected. Patients' periodontal status was examined at different time points during pregnancy or after delivery (at 14-32 weeks of gestation, within 48 h prior to or within 5 days after delivery). Pooled odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were calculated for cases and controls. Cases were defined as women with concurrent hypertension and proteinuria after 20 weeks of gestation. Eleven studies involving 1118 women with preeclampsia and 2798 women without preeclampsia were identified and analyzed. Women with periodontal disease before 32 weeks of gestation had a 3.69-fold higher risk of developing preeclampsia than their counterparts without periodontal disease (OR=3.69; 95% CI=2.58-5.27). Periodontal disease within 48 h prior to delivery was associated with a 2.68-fold higher risk of preeclampsia (OR=2.68; 95% CI=1.39-5.18). Pregnant women with periodontal disease within 5 days after delivery had a 2.22-fold higher risk of preeclampsia than women without periodontal disease (OR=2.22; 95% CI=1.16-4.27). In conclusion, this meta-analysis suggests that maternal periodontal disease is an independent predictor of preeclampsia.

OBJECTIVETo explore the clinical effects of total vertebral column resection combined with anterior mesh cage support in treating severe congenital kyphoscoliosis.

METHODSFrom April 2008 to April 2012,21 patients with severe congenital kyphoscoliosis were treated with total vertebral column resection and internal fixation through posterior approach combined with anterior mesh cage support. There were 8 males and 13 females with an average age of 19.4 years old (ranged from 10 to 35). And 6 cases were thoracic segments deformity,13 cases were thoracolumbar segments and 2 cases were lumbar segments, of them, 2 cases were accompanied with Chairs deformity, 6 cases with diastematomyelia, 4 cases with syringomyelia,and 1 case with neurofibromatosis. According to the Frankel grade system, 3 cases were grade C, 5 cases grade D and 13 cases grade E. Blood loss, operative time, and perioperative complications were recorded. Coronal and sagittal Cobb angle, apical vertebral offset distance, sagittal offset, the relative height of shoulders, razor back deformities were measured and analyzed before and after operation.

RESULTSThe average operative time was 5.2 h (3.5 to 6.5 h) and blood loss was 2,500 ml (1,400 to 4,900 ml). The 2nd day after operation, apical vertebral offset distance, sagittal offset, the relative height of shoulders, razor back deformities had obviously improved than preoperative (P < 0.05). There was no significant difference in above items between postoperative on the 2nd day and final follow-up (P > 0.05). The corrective rate of kyphosis and scoliosis were (60.97 +/- 6.30)% and (62.24 +/- 5.82)%, respectively. On the first day after surgery,2 cases of Frankel grade E aggravated to grade D, and obtained recovery at 2 week after conservative treatment. And 1 case palinesthesia later,grade D aggravated to grade C and obtained recovery after revision surgery in time. One case complicated with permanent blindness of left eye, 1 case occurred injury of pleura and 2 cases had cerebrospinal fluid leak during operation. All patients were followed up from 9 to 31 months with an av- erage of 18.6 months. At final follow-up,all patients obtained bone union, Frankel grade D in 4 cases and grade E in 17 cases, no correction loss and internal fixation loosening was found.

CONCLUSIONTotal vertebral column resection combined with anterior mesh cage support can effectively correct kyphosis and scoliosis in severe congenital kyphoscoliosis and can avoid injury of spine cord by spinal crispation, but intraoperative position and neurologic complications should still be considered.

Purpose: This study aimed to explore the role of the long non-coding RNA (lncRNA) RNA component of mitochondrial RNAase P (RMRP) in sepsis-induced acute kidney injury (AKI). Materials and Methods: Venous blood was collected from septic patients and healthy people. C57BL/6 mice who underwent cecal ligation and puncture (CLP) were used as in vivo models of septic AKI. Lipopolysaccharide (LPS)-induced HK-2 cells were employed as in vitro models of AKI. Flow cytometry analysis was conducted to detect cell apoptosis. Enzyme-linked immunosorbent assay and Western blot assays were used to detect levels of pro-inflammatory cytokines. Results: RMRP was upregulated in sera from patients with AKI and in LPS-induced cells. Knockdown of RMRP inhibited cell apoptosis and reduced production of inflammatory factors in LPS-induced cells, as well as alleviated AKI in CLP mice. RMRP facilitated inflammation by activating NACHT, LRR, and PYD domains-containing protein 3 (NLRP3) inflammasome. We found that microRNA 206 (miR-206) binds with and is negatively regulated by RMRP: miR-206 directly targets the 3’ untranslated region of DEAD-box helicase 5 (DDX5) and negatively regulates DDX5 expression. By binding with miR-206, RMRP upregulated DDX5 expression. Rescue assays revealed that overexpression of DDX5 counteracted the effect of RMRP inhibition on cell apoptosis and inflammatory response in LPS-induced cells. Conclusion The lncRNA RMRP contributes to sepsis-induced AKI through upregulation of DDX5 in a miR-206 dependent manner and through activation of NLRP3 inflammasome. This novel discovery may provide a potential strategy for treating AKI.

The purpose of this study was to investigate whether pretransplant infusion of reactive natural killer cells (NK cells) from donor or recipient can reduce graft-versus-host disease (GVHD) and enhance engraftment in bone marrow transplantation (BMT). Recipient BALB/c mice were divided into 4 groups after received 6.5 Gy total-body irradiation (TBI): control group 1 was treated with nothing, control group 2 received BMT alone, experiment group 1 received BMT and autoreactive NK cells, experiment group 2 received BMT and alloreactive NK cells. Life span, clinical and pathologic changes of GVHD and chimerism rate of each group were evaluated. The results showed that all mice were survival in control group 1. The life span was shorter in experiment group 1 than that in control group 2 (P < 0.05) and longer in experiment group 2 than that in control group 2 (P < 0.01). GVHD was higher in score of experiment group 1 than in control group 2 (P < 0.05) but lower in experiment group 2 than that in control group 2 (P < 0.01). The donor chimerism rate in both two experiment groups were higher than that in control group 2 (P < 0.05), however, the donor chimerism rate was higher in experiment group 2 than that in experiment group 1 (P < 0.01). It is concluded that pretransplant infusion of alloreactive donor NK cells can prolong life span, reduce the degree of GVHD and enhance engraftment. But autoreactive recipient NK cells can shorten life span, aggravate the degree of GVHD and also enhance engraftment, which is weaker than that using alloreactive donor NK cells.

To investigate the effects of DENV infection on the expression of Vascular endothelial growth factor (VEGF) in monocytes, and to explore which innate immune signaling pathway is responsible for VEGF induction. Real-time PCR was used to determine the expression levels of VEGF in DENV-infected THP-1. We found that different serotype viruses (DENV1, DENV2, DENV3) induced the VEGF expression. Moreover, VEGF expression was significantly increased in human primary monocytes infected with DENV 2. In addition, VEGF induction by DENV2 was significantly impaired by knockdown of TLR3 and interferon-beta promoter stimulator 1 (IPS-1), or by inhibition of ERK, JNK or NF-kappaB. These results demonstrated that DENV induced VEGF expression in monocytes, and the activation of TLR3, IPS-1 signal pathways were required for DENV2-triggered VEGF induction, suggesting that VEGF might be a promising therapeutic target for DHF.

OBJECTIVEChemokine receptor CXCR4 and its ligand stromal-derived factor 1 alpha (SDF-1alpha) have been paid increasing attention for their involvement in megakaryocytic hematopoiesis. It has been revealed in recent years that they can induce mature and immature megakaryocytes (MKs) to migrate through bone marrow endothelial cells (BMEC) by increasing the affinity of MKs for BMEC. Thus MKs maturity and eventual release of platelet from MKs ensues. While maturity disturbance of MKs and impaired production of platelets have been regarded as the main pathogenesis of ITP, the mechanism of which still remains unclear. Therefore, a clear understanding of the levels of CXCR4 and SDF-1alpha within bone marrow in children with ITP will help us to elucidate further the mechanism of ITP as well as to provide direct theoretical evidence for predicting treatment effect and evaluating prognosis.

METHODSBone marrow were aspirated from 28 children with AITP and 12 normal children. Percoll density gradient and immunomagnetic beads method were used to purify megakaryocytes from the bone marrow. The immune cytochemistry was used to detect CXCR4 on megakaryocytes. The levels of SDF-1alpha were detected by ELISA. SPSS10.0 statistical software was used to deal with the experimental data.

RESULTSBefore the treatment in children with AITP, both the CXCR4 expression on megakaryocytes and the SDF-1alpha level in bone marrow plasma were markedly decreased compared with the normal controls (P < 0.05). As to the cases who were sensitive to the high-dose intravenous immunoglobulin (HDIVIgG), the CXCR4 and SDF-1alpha levels were much higher in children after the treatment than those before the treatment (P < 0.05). In 6 cases insensitive to HDIVIgG, before the treatment the CXCR4 level was much lower than the children sensitive to HDIVIgG (P < 0.05).

CONCLUSIONSThe low levels of CXCR4/SDF-1alpha system in bone marrow may be one of the factors which contribute to the maturity disturbance of megakaryocytes and disturbance of platelets production in AITP, while decreased CXCR4/SDF-1alpha system may be caused by the effect of autoantibody against platelet. The mechanism of HDIVIgG in the treatment of AITP may involve in the increasing expression of CXCR4/SDF-1alpha system. The level of CXCR4 on megakaryocytes may play a certain role in predicting the treatment effect of immunoglobulin.
