Conclusion The ulcer of the patients with diabetic foot was closed early and the blood supply of the limb have been reconstructed by microsurgical treatment,it can not only avoid amputation or lower the limb amputation level,but also improve the life quality of patients and obtain social benefit.

OBJECTIVETo investigate the role of single nucleotide polymorphisms of the gene of diacylglycerol kinase κ (DGKK) in hypospadias in Chinese children.

METHODSWe performed direct sequencing on 2 hypospadias-related candidate single nucleotide polymorphisms of the DGKK gene (rs1934179 and rs7063116, never previously reported in the Chinese population) from 300 children with sporadic hypospadias and 200 healthy controls, and compared the results between the two groups.

RESULTSThe mutation frequencies of rs1934179 and rs7063116 were 5.0% (15/300) and 5.67% (17/300) respectively in the hypospadias patients, significantly higher than 1.5% (3/200) and 2.0% (4/200) in the normal controls (P <0.05). The mutation frequencies of rs1934179 and rs7063116 in the cases of distal and middle hypospadias were also remarkably higher (6.5%, [13/200] and 7.5% [15/200], P <0.05), but those in the proximal cases (both 2.0% [2/100]) showed no statistically significant difference from the control (P >0.05).

CONCLUSIONThe polymorphisms of the DGKK gene may be associated with hypospadias, particularly distal and middle hypospadias, in Chinese children.

Objective To evaluate the surgical approaches, surgical timing and materials for cranial defect repair in children. Methods From the year 2002 to 2006, 4 children with cranial defect received cranial reconstruction using absorbable poly-L-lactic acid (PLA) material and hydroxyapatite. Results The 3-year follow-up showed that the cranial defect was successfully repaired using the absorbable material in 3 patients and failure of repair occurred in 1 patient. Conclusion Cranial defect in children can be effectively repaired using absorbable materials and hydroxyapatite without obviously affecting the skull development. This approach provides an important option for cranial defect repair in children.

OBJECTIVETo observe the effect of Compound Zhajin Granule (CZG) on Toll-like re-ceptor 4 (TLR4) signaling pathway in high-fructose corn syrup induced NASH mice.

METHODSThirty 6-week-old male C3H mice were divided into the high fat and high fructose (HFHFr) group (n = 20) and the control group (n = 10) according to body weight. Mice in the HFHFr group ate high fat diet and drank 20% fructose water, while those in the control group ate common diet and drank common water. After 8 weeks mice in the HFHFr group were divided into two group according to body weight, the HFHFr group and the CZG group, 10 in each group. Mice in the CZG group were fed with high fat forage and 20% fructose water, and administered with 50 mL/kg 12. 8% CZG (prepared by hawthorn, Radix Curcumae, Alisma Orientale, Fritillaria Thunbergii, Silybum Marianum, peach seed in the ratio of 3:1.5:1.5:2:1.5:2:1) by gastrogavage. Mice in the HFHFr group were fed in the same way and daily administered with equal volume of distilled water by gastrogavage. Sixteen weeks later all mice were sacrificed. Body weight, liver wet weight, liver function, and lipid metabolism were detected. Pathological changes of liver tissues were assessed by HE staining, oil red O staining, and Masson staining. Expressions of TLR4, myeloid differentiation factor 88 (MyD88), tumor necrosis factor-alpha (TNF-α) were detected using immunohistochemical staining and real-time fluorescent quantitative PCR.

RESULTSBody weight, alanine aminotransferase (ALT), aspartate aminotransferase (AST) were obviously lower in the CZG group than in the HFHFr group (P < 0.05); oil red O stained area and density were decreased more in the CZG group than in the control group. HE staining showed ballooning inflammation was reduced more in the CZG group than in the HFHFr group. Masson staining was negative. Positive rates of TLR4 and MyD88 and mRNA expressions were significantly lower in the CZG group than in the HFHFr group (all P < 0.05).

CONCLUSIONCZG could significantly inhibit TLR4 signaling pathway of liver in NASH mice.

OBJECTIVETo clone, identify and phylogenetically characterize a clade B-Thai HIV isolate representing the most prevalent virus in Henan province.

METHODSPeripheral blood mononuclear cells (PBMCs) from an HIV-1 infected patient in Henan Province were separated, and co-cultivated with phytohemagglutinin-stimulated healthy donor PBMCs. Proviral DNA was extracted from productively infected PBMCs. The full-length HIV-1 genome was amplified by using the LA Tag long template PCR system. Primers were positioned in conserved regions within the HIV-1 long terminal repeats. Purified PCR products were T-A ligated into a pWSK29-T vector(CNHN 24 clone). Three recombinant clones containing virtually full-length HIV-1 genome were identified by PCR. The full-length genome was sequenced by using the primer-walking approach. Nucleotide sequence similarities were calculated by the local-homology algorithm. Phylogenetic trees of gag, pol and env reading frames were constructed using the Phylip software.

RESULTSHIV-1 C3V4 sequences indicate that the epidemic in this area was B-Thai subtype. V3 loop multiple amino acid sequence alignments showed amino acid alterations at nine positions. The 9,010 bp genomic sequence derived from isolate CNHN 24 contained all known structural and regulatory genes of an HIV-1 genome. No major deletions, insertions, or rearrangements were found. The highest homologies of the gag, pol, vpr, and vif reading frames to the corresponding clade B-Thai RL 42 sequences were 95.42%-97.08%. Phylogenetic trees showed the closest relationship of CNHN 24 and RL 42.

CONCLUSIONThe cloning and characterization of a virtually full-length HIV-1 B-Thai subtype in central China was completed in our laboratory. The data should be helpful to future studies on the genetic diversity of HIV-1.

OBJECTIVETo explore the relationship between neuropeptide substance P (SP) and wound healing in scalded rats.

METHODS(1) Scalded rats with different degrees of scald injury were employed as the experimental model and were sacrificed at 24 post scald hour (PSH), and on 3, 7 and 14 post scald days (PSD). The SP content in the wound was detected with radioimmunoassay method. (2) The murine granulation tissue fibroblasts (GTF) were cultured with different culture media, and divided into control, SP and Spantide (SP receptor antagonism) groups. The effects of SP and Spantide on the cellular activity and apoptotic rate of murine GTF were assessed in vitro.

RESULTSThere was significant difference of the SP content among the superficial (145 +/- 78) ng/g, partial (94 +/- 48 ng/g) and full thickness (53 +/- 27 ng/g) scald wounds at 24 PSH (P < 0.01), while the SP content in partial thickness burn wound on 3 and 7 PSD obviously increased; and that in deep partial thickness burn wound obviously increased on 7 and 14 PSD. But the SP content remained unchanged in full thickness scald wound. (2) SP could promote the activity of GTF and inhibit its apoptosis (The GTF activity in control, SP groups were 0.21 +/- 0.05, 0.36 +/- 0.07, respectively, P < 0.01). Spantide could inhibit the interaction between SP and GTF.

CONCLUSIONSP can promote GTF proliferation, and the SP content in wound is closely associated with the depth of the injury and wound healing capacity.
