Objective To provide anatomical information and clinical application of flaps based on the proximal ulnar artery perforators.Methods Ten fresh cadavers who underwent injected with artery imaging technology and dissected with layer by layer;Eighteen patients who sought surgical treatment with proximal ulnar artery perforator flap for soft tissue defects of the finger and dorsum wrist at our hospital between October 2011 and November 2012 were included in this study.Results The diameter and superficial length of the main perforator respectively were 0.5-0.9 mm and 33.0-47.0 mm in our dissection.There were 5-9 perforators given from the ulnar artery to supply skin over the medial side of the forearm.All of the 18 flaps survived after surgeries.The flap size ranged from 3.0 cm × 2.5 cm to 10.0 cm × 5.5 cm.All of the transplanted flaps presented favourable contours and good functions at 6 to 12 months' followed-up.Conclusion Proximal ulnar arter perforator flap has favourable appearance,constant vascular pedicle,reliable blood supply,and large diameter.The free transplantation of this flap offers a satisfactory alternative for repairing the small and medium-sized area of soft tissue defects of forearm and hand.

Objective：To investigate the changes of calcitonin gene-related peptide immunoreactive (CGRP-IR)nerve fibers in rat dental pulps during acute inflammation. Methods： Rat acute pulpitis model was established by silk thread ligation and the change of CGRP-IR nerve fibers was observed with immunohistochemical method.Results： In radical pulp,the CGRP-IR nerve fibers became denser and more heavily stained；in the coronal pulp,the number of CGRP-IR nerve fibers decreased,but the background staining was heavier. Conclusion： During acute inflammation,the amount of CGRP increases in dental pulps, and is released into the surronding tissue in a large scale in the coronal region.

4.00 ng/ml) were divided into BPH group (without inflammation), acute inflammation group and chronic inflammation group. The diagnosis was confirmed by transrectal-ultrasound guided needle biopsies. Prostate volumes were measured in all patients by the transrectal-ultrasound. A total of 126 patients were included in this study. The biopsy results showed 47 patients in BPH group, 45 patients in acute inflammation group and 34 patients in chronic inflammation group. Results The serum PSA value in the BPH group, acute inflammation group and chronic inflammation group were (5.76?3.21),( 8.67 ?2.92 ) and (5.54?3.01) ng/ml respectively. The serum PSA value in acute inflammation group was much higher than that of BPH group and chronic inflammation group(P

Objective To investigate the effects of continuous positive airway pressure (CPAP) on the levels of hemorheology and C-reactive protein in patients with obstructive sleep hypopnea apnea syndrome (OSAHS). Methods 58 moderate to severe OSAHS subjects were selected as treatment group and 32 healthyadults were selected as control group. Hemorheology and C-reactive protein in all subjects were examined and compared. The levels of hemorheology and C-reactive protein were also examined and compared before and after 3 months CPAP treatment in treatment group. Results In treatment group, the levels of the whole blood viscosity and hs-CRP were significantly higher than those in control group (P < 0.01). After treatment of CPAP for three months, the levels of the whole blood viscosity and hs-CRP obviously decreased (P < 0.01). Conclusion Levels of hemorheology and hs-CRP are elevated in patients with OSAHS and CPAP therapy could effectively decrease serum levels of hemorheology and hs-CRP in patients with OSAHS.

TLR4-MD-2 complex plays a key role in LPS recognition and its signal transduction. These steps are the vital elements of the host's defensive reaction. Studying the functional domain of TLR4 and MD-2 is very important to further understand the mechanism of LPS signal transduction. It was studied the interaction domain of TLR4 and MD-2 in living cells based on gene mutation, gene transfection and fluorescence resonance energy tramsfer(FRET) which is considered as one of the best methods used for intracellular protein-protein interaction study. CY-15P which was fused by CFP and YFP through 15 neutral amino acids was used as positive control, while co-expressed CFP and YFP proteins were used as negative control. The results showed that the ability of TLR4 binding to MD-2 decreased dramatically after the deletion of Glu~(24) ～ Met~(41) in N terminal of TLR4. Aggregation of TLR4 to LPS stimulation was observed, however, TLR4 without the Glu~(24)～ Met~(41) mutation did not aggregate. All these results indicated that TLR4 Glu~(24)～ Met~(41) might be the interaction domain of TLR4 binding to MD-2 and participate in the aggregation effect of TLR4 upon LPS stimulation.

Objective To investigate immunological relationship between early induction of food allergy and occurrence of later asthma in mice, and explore the pathological changes in lung tissues. Methods Thirty-seven female BALB/c mice aged 6 weeks were randomly divided into blank control group ( n = 12), food allergy group ( n = 13) and asthma group (n = 12). After being challenged by ovalbumin (OVA), the levels of serum IgE, IL-4 and INF-γ in bronchoalveolar lavage fluid ( BALF) were detected. The numbers of inflammatory cells and eosinophils ( EOS) in BALF were counted. Lung tissues were obtained for pathological sections, and thickness of bronchial wall and EOS infiltration were observed. Results The level of serum IgE and level of IL-4, ratio of IL-4/IFN-γ and number of EOS in BALF in food allergy group and asthma group were significantly higher than those in control group (P <0.05). The level of IL-4 and number of EOS in BALF in asthma group were significantly higher than those in food allergy group (P <0.05) , while there was no significant difference in serum IgE level between these two groups (P > 0.05), and levels of IFN-7 in BALF in both groups were significantly lower than that in blank control group (P<0.05). There were more EOS infiltration in lung tissues and thicker bronchial wall in food allergy group and asthma group than that in blank control group (P < 0.05), and the number of EOS in asthma group was significantly higher than that in food allergy group ( P < 0.05). Conclusion IgE-mediated immune response is involved in both food allergy and asthma mouse models. Lung immune imbalance of Thl/Th2 and inflammatory cell infiltration caused by food allergy may participate in the occurrence of later asthma.
