OBJECTIVETo dicuss the application and therapeutic effect of middle-forearm flap based on perforator of ulnar artery for electrical burn wound on the wrist.

METHODSFrom Oct. 2009 to Oct. 2012, 10 cases of electrical burn wounds on the wrist were treated. A line from radialis medial epicondyle of humerus to the interior radialis pisiform bone was connected as flap axis. At the midpoint of the line, Doppler flow imaging meter was used to detect the emerging point of perforator vessel. The flap was designed and harvested. The flap was transferred reversely, with superficial vein retaining which was anastomosed with vein at recipient sites in 3 cases. The wounds in the donor sites were closed directly in 2 cases, and with skin graft in 8 cases.

RESULTSAll the 10 flaps survived completely. 7 cases without vein anastomosis underwent obvious flap edema during 2-4 days postoperatively, which resovled 1 week later. Sub-flap tissue necrosis and infection happened in 2 cases, which healed after dressing and drainage. Patients were followed up for 3-36 months with satisfactory results.

CONCLUSIONSThe middle-forearm flap based on perforator of ulnar artery has a stable and reliable blood supply. It offers a new choice for the electric burn wound on the wrist, especially at the ulnar side.

The results showed that the linearity ranges ofhesperidin,magnolol,honokioland liquiritinwere 4.47-178.70 μg·mL-1, 3.42-136.96 μg·mL-1, 3.49-139.48 μg·mL-1, 3.92-157.20 μg·mL-1, respec-tively (r>0.999). The average recoveries of them were 99.48%, 99.05%, 99.57% and 99.79%, respectively. It was concluded that the method was accurate, sensitive and specific for quality control of Soft Capsule JWHXZQ.

ObjectiveTo study the role of Kukoamine B (KB) in inhibiting the inflammatory response of small intestine in septic mice and its molecular mechanisms.Methods Twenty-four male ICR mice were randomly divided into control group, model group, and KB intervention group (each,n= 8). Sepsis model was reproduced by intra-peritoneal injection of 20 mg/kg lipopolysaccharide (LPS), while equivalent normal saline was given in control group, and 20μg/kg KB was injected through caudal vein 4 hours after LPS challenge in KB intervention group. The blood/tissue samples (jejunum and ileum) were harvested 8 hours after LPS injection. The levels of plasma LPS, tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were measured. The pathological changes in small intestine tissues were observed under light microscope, while the levels of inflammatory cytokines TNF-α and IL-1β in the tissue homogenates (jejunum and ileum) were assessed by enzyme linked immunosorbent assay (ELISA). The activity of myeloperoxidase (MPO) was measured by colorimetry. The expression of intercellular adhesion molecule-1 (ICAM-1) was determined by immunohistochemistry. The expressions of inducible nitric oxide synthase (iNOS) mRNA was assayed by reverse transcription-polymerase chain reaction (RT-PCR). The activation of nuclear factor-κΒ (NF-κΒ) was determined by Western Blot.Results The mice in model group were found to have an increase in microvascular permeability, interstitial edema, and infiltration of white blood cells, and the levels of LPS, TNF-α and IL-1β in their plasma, with an increase in concentrations of TNF-α and IL-1β, activity of MPO, positive expression of ICAM-1, expression of iNOS mRNA and NF-κB protein in small intestine (jejunum and ileum). Compared with model group, in mice with KB intervention, microvascular permeability, interstitial edema, and infiltration of white blood cells were reduced significantly, while the levels of LPS, TNF-α and IL-1β in plasma, the concentration of TNF-α and IL-1β, the activity of MPO, the positive expression of ICAM-1, the expression of iNOS mRNA and NF-κB protein in small intestine (jejunum and ileum) were significantly decreased [plasma LPS (kEU/L): 654.09±28.13 vs. 1 155.65±47.15, TNF-α (ng/L): 12.75±0.47 vs. 30.61±0.71, IL-1β (ng/L): 53.06±5.32 vs. 64.47±2.61; jejunum TNF-α(ng/L): 43.27±1.20 vs. 64.82±2.09, IL-1β (ng/L): 326.38±14.47 vs. 535.22±13.48, MPO (U/g): 0.14±0.01 vs. 0.32±0.02, iNOS mRNA (2-ΔΔCt): 2.39±0.13 vs. 10.80±0.22, NF-κB protein (gray value): 0.687±0.062 vs. 1.404±0.046; ileum TNF-α (ng/L): 62.75±3.92 vs. 104.24±2.82, IL-1β(ng/L): 408.06±1.70 vs. 521.97±1.16, MPO (U/g): 0.36±0.08 vs. 0.66±0.05, iNOS mRNA (2-ΔΔCt): 1.65±0.11 vs. 3.59±0.29, NF-κB protein (gray value):0.830±0.114 vs. 1.609±0.051, allP< 0.05].Conclusion KB can combine with LPS and inhibit LPS/Toll-like receptor 4 (TLR4) signaling pathway, thereby significantly inhibit the inflammatory response and protect the function of the small intestine in LPS-induced septic mice.

Objective To investigate the effect of methylprednisolone on T helper 17 cell (Th17 cells) related cytokines (interleukin (IL)-23,17A,21,22,6,and tansforming growth factor (TGF)-β) in serum and cerebrospinal fluid from patients with relapsing remitting multiple sclerosis and their effects on the pathogenesis.Methods We recruited relapsing remitting multiple sclerosis group (38 patients)and noninflammatory neurological disease group (20 controls),and detected the levels of IL-23,IL-17A,IL-21,IL-22,TGF-β and IL-6 in serum and cerebrospinal fluid (CSF) with ELISA kit in both controls and patients before and after treatment by methylprednisolone.Results After treatment in relapsing remitting multiple sclerosis patients,IL-17A,IL-23,IL-21,and IL-22 levels in cerebrospinal fluid and serum were significantly decreased,however,they were still higher than that in the non-inflammatory neurological disease patients.TGF-β levels was significantly increased (serum:(17.2 ± 5.9) pg/ml vs (34.1 ± 6.5) pg/ml,t =14.351,P =0.000 ; CSF:(26.4 ± 4.7) pg/ml vs (73.2 ± 19.7) pg/ml,t =16.352,P =0.000).The levels of TGF-β in serum and CSF in patients before treatment were lower than those of in non-inflammatory neurological disease patients (serum:(30.2 ± 8.9) pg/ml,t =6.769,P =0.012 ; CSF:(3 1.4 ± 7.5) pg/ml,t =9.368,P =0.017).However,the levels of TGF-β in CSF in patients after treatment were significantly higher than those in non-inflammatory neurological disease patients (t =9.138,P =0.000).Correlation analysis showed that IL-23 and IL-17A were positive correlation in the serum of relapsing remitting multiple sclerosis patients before treatment.Moreover,positive correlations among IL-23,IL-17A and IL-21 were detected in the CSF of relapsing remitting multiple sclerosis patients before treatment.Conclusions Decreased levels of IL-23,IL-17A,IL-21 and IL-22,and elevated levels of TGF-β were detected in serum and CSF of patients with relapsing remitting multiple sclerosis after methylprednisolone treatment.IL-23,IL-17A,IL-21,IL-22 and TGF-β might involve in the pathogenesis of relapsing remitting multiple sclerosis.
