BACKGROUND:Recently, the clinical repair methods of irregular wound on fingers primarily include local pedicled flap and free mini-flap of upper extremities or lower extremities.
OBJECTIVE:To discuss the application of free mini-flap derived from upper limb in repairing the wound on fingers.
METHODS:From December 2010 to February 2014, 12 patients with irregular wounds on 12 fingers were selected from Department of Traumatic Orthopaedics and Hand Surgery, First Affiliated Hospital of Guangxi Medical University, China. The size of wounds ranged from 1.5 cm × 2.0 cm to 3.0 cm × 4.5 cm with different degrees of bone or tendon exposure. After the debridement, 12 patients were treated by free mini-flaps of upper limb. The donor sites were directly sutured.
RESULTS AND CONCLUSION:Among the 12 patients, al the wounds at recipient and donor sites were healed at stage I, and the free mini-flags survival completely. Al of patients were fol owed up for 3-6 months (average 4.5 months). Free mini-flags had good appearance and needn’t undergo secondary trimming. The active motion of fingers was improved dominantly. According to the criteria of Hand Surgery Association Society of Chinese Medical Association Society for the function evaluation of upper limb, three cases were excellent, eight were good, and only one was bad. The excellent and good rate was 91%. Free mini-flaps of upper limb are an ideal method for repair of wounds on fingers. It has no injury to normal tissue in hands, donor site is very secluded, and the short-term curative effect is good.

AIM: To explore the predisposing factors, population characteristics and clinical features of severe fungal keratitis.
METHODS:The data of 233 cases 233 eyes of severe fungal keratitis in my hospital from January, 2008 to November, 2013 was retrospectively reviewed. The predisposing factors, population characteristics and clinical features were analyzed.
RESULTS: In 233 cases of severe fungal keratitis, the number of male patients was 153 ( 65. 7%) and the number ratio of male to female was 1. 9:1. The average age of them was (52. 7±11. 3), and most of them were middle-aged and elderly people living in the rural area (78. 1%) and were farmers ( 66. 1%) with low literacy (59. 7%). In 233 cases, 188 cases (80. 7%) possessed a clear history of ocular trauma, mainly caused by plant-based trauma (60. 9%). 90 cases (57. 3%) were infected with Fusarium, and 47 cases ( 29. 9%) by Aspergillus. The main treatment of severe fungal keratitis was surgery (87. 9%). 83 cases ( 52. 9%) were treated with penetrating keratoplasty, and in Fusarium and Aspergillus infected patients with severe fungal keratitis, 58. 4% ( 80/137 ) were performed with penetrating keratoplasty. In addition, patients treated with eye enucleation or evisceration, 68. 4% (13/19) were infected with Fusarium species.
CONCLUSION: Patients with severe fungalkeratitis in our hospital are mainly elderly male farmers living in rural, because of low economic condition and poor diagnosis consciousness. The main pathogens are Fusarium and Aspergillus species, and the major treatment is penetrating keratoplasty. Most of patients with poor clinical outcomes are infected with Fusarium species.

Objective To investigate the expressions of Livin and vascular endothelial growth factor (VEGF)in pancreatic carcinoma and their cilinical significances.Methods The expressions of Livin and VEGF proteins were tested by immunohistochemistry in 68 cases of pancreatic carcinomas and 44 cases of adja-cent paracancerous tissues.Results The positive rates of Livin in pancreatic carcinomas and adjacent paracan-cerous tissues were 73.5% and 4.5% respectively,and the difference was statistically significant (χ2 =48.137,P<0.001).The positive rates of VEGF in pancreatic carcinomas and adjacent paracancerous tissues were 69.1% and 13.6% respectively,and the difference was statistically significant (χ2 =29.147,P <0.001).The expressions of Livin and VEGF were related with tumor differentiation (χ2 =6.061,P=0.014;χ2 =6.592,P=0.010),TNMstage (χ2 =4.175,P=0.041;χ2 =9.992,P=0.002),lymph node metasta-sis (χ2 =11.731,P=0.001;χ2 =12.002,P=0.001)and neural invasion (χ2 =9.950,P=0.002;χ2 =7.433,P=0.006).Significantly positive correlation was found between the expressions of Livin and VEGF by using Spearman correlation analysis (r=0.320,P=0.008).Survival analysis showed that the expressions of Livin and VEGF were independent prognostic factors in pancreatic carcinoma.Conclusion Livin and VEGF involve in the development,migration and metastasis of pancreatic carcinoma.Livin may upregulate the expres-sion of VEGF,which may lead to the angiogenesis and migration in pancreatic carcinoma.

In recent years, the discovery and studies on aquaporin have made us have a more in-depth understanding about the physiological and pathological processes of water metabolism. Over years, however, there has been no quantitative study on the target sites of diuretic traditional Chinese medicines at the molecular level. In that case, aquaporin was found to been a new target molecule to explain the efficacy exertion of diuretic traditional Chinese medicines. By studying aquaporin, researchers can understand the implicit meaning of the diuretic effect of traditional Chinese medicines and conduct quantitative studies on the diuretic effect. So far, many scholars have conducted a series of studies in the traditional Chinese medicine field by using the findings on aquaporin and made certain advances. This article provides a summary about the efficacy exertion of diuretic traditional Chinese medicines through target molecule aquaporin.

The amino acid contents of five floral sources Chinese honeys (jujube, rape, chaste, acacia, and lungan) were measured using reversed phase high-performance liquid chromatography (RP-HPLC). The results showed that proline was the main amino acid in most of the analyzed samples. Phenylalanine presents at the highest content in chaste honey samples, and the total amino acid contents of chaste honeys were also significantly higher than those of other honey samples. Based on the amino acid contents, honey samples were classified using chemometric methods (cluster analysis (CA), principal component analysis (PCA), and discriminant analysis (DA)). According to the CA results, chaste honeys could be separated from other honeys, while the remaining samples were correctly grouped together when the chaste honey data were excluded. By using DA, the overall correct classification rate reached 100%. The results revealed that amino acid contents could potentially be used as indicators to identify the botanical origin of unifloral honeys.

Objective To study the expression of Snail in laryngeal carcinoma and to explore its relationship with invasion and metastasis in subgroup laryngeal carcinoma cells. Method The expression of Snail protein was examined by immunohistochemistry staining in the tissue of laryngeal carcinoma. The statistical evaluation was performed to detect the correlation between the Snail protein expression and clinical features. In different subgroups of laryngeal carcinoma cells (CD 44+CD 133+cells, CD 44 and CD 133-cells), the expression of Snail and adhesion molecules E-cadherin were detected by RT-PCR,Western blot test and immunochemical staining which were studied in the correlation with invasion and metastasis. Results The result of immunohistochemical staining revealed that Snail was moderately or highly expressed in the tissue of laryngeal carcinoma significantly and higher than those in adjacent non-cancerous tissues(P<0.01). Expression of Snail was highly correlated with lymph node metastasis, tumor differentiation and clinical classification(P<0.05).However, it was not related to the age , gender and clinical type. RT-PCR and Western blot test results confirmed that the expression level of Snail was significantly higher in CD 44+CD 133+laryngeal cancer cells than in CD 44-and CD 133-laryngeal cancer cells, otherwise the expression level of E-cadherin in CD 44+CD 133+laryngeal cancer cells was significantly lower than in the CD 44-and CD 133-laryngeal cancer cells. Cell immunohistochemical staining confirmed the expression of Snail and E-cadherin were negatively correlated in CD 44+CD 133+laryngeal cancer cells. Conclusion Over expression of Snail in laryngeal carcinoma is closely related to the development of laryngeal cancer and lymph node metastasis. The expression of Snail in the CD 44+CD 133+laryngeal cancer cell subgroup is negatively correlated with adhesion molecules E-cadherin, which is a close correlation with invasion and metastasis of laryngeal cancer cells.
