ObjectiveTo introduce clinical experience of the modified lateral crural reverse island skin flap with two sets of blood supply system for aged ankle & foot soft tissue defect.MethodsOn the anatomy base that cutaneous artery branches of lateral crural reverse island skin flap and perforating branches of sural neurocutaneous vascular flap were originated from peroneal artery, we designed the modified lateral crural reverse island skin flap located in posterolateral cruris treated for aged ankle & foot soft tissue defect. The modified flap had two sets of blood supply system which were from lateral crural flap and sural neurocutaneous flap.ResultsAll 11 flaps survived. The skin grafting of donor sites healed well. Followed up 3-9 months, six cases were satisfactory. Five cases with extensor defect were regained by tendon transplantation after 3 months of the operations.Conclusion The modified lateral crural reverse island skin flap with two sets of blood supply system is a good method for aged ankle & foot soft tissue defect.

BackgroundMonocyte chemotactic protein-1 (MCP-1)plays an important role in the tumor,inflammation,diabetic retinopathy and other neovascular disease,but the expression and the role of MCP-1 in the oxygen induced retinopathy(OIR) model have rarely been reported. Objective This study was to investigate the expression of MCP-1 in the retina development of newborn mouse and in mouse models with OIR.Methods C57BL/6J newborn mice were divided into two groups and 60 mice in each group.Mice in OIR group were exposed to 75％ oxygen for 5 days and then to room air.All mice in normal control group exposed to room air only.Ten mice in each group were randomly chosen and sacrificed at postnatal 5,7,12,14,17,21 days.The expression of MCP-1 in mouse retina was detected with the method of immunohistoehemistry and reverse transcription polymerase chain reaction(RT-PCR).Results MCP-1 positive cells were seen in normal mouse retina.Up-regulation of MCP-1 positive cells was detected both in 12 days in normal control group and in 14 days in OIR group.MCP-1 mRNA was detected in mouse retina at 5 days,and a transient up-regulation of MCP-1 mRNA was observed in 12 days in normal control group.MCP-1 mRNA in OIR group significantly increased in 14 days in comparison with the normal control group( P =0.028,P =0.001 ). Conclusions Expression of MCP-1 is detectable in whole retinal development procession of mice.A transient up-regulation of MCP-1 expression is detected in the critical period of retinal vascular development in mice models with OIR,which is closely related to the retinal vascular development and progression of retinal new vessels.

Background Various studies have suggested that inflammatory factors such as leucocytes and macrophages are involved in the occurrence and development of diabetic retinopathy (DR),and many cytokines promote the occurrence of DR.However,the relationship of aqueous and serum monocyte chemotactic protein-1 (MCP-1) and macrophage migration inhibitory factor (MIF) change with DR is unclear.Objective This study was to investigate the effects of MCP-1 and MIF in aqueous and serum during DR development.Methods Eighty patients with type 2 diabetes were enrolled from Beijing Shijitan Hospital.These patients received phacoemulsification or phacoemulsification and vitrectomy from September,2010 to June,2011.Twenty-six cataract patients in the same stage (without diabetes) who underwent phacoemulsification surgery served as controls.According to the clinical stage of the DR,the diabetic patients were classified as the non-DR group (NDR) (20 eyes),non-proliferative DR group (NPDR) (38 eyes) and proliferative DR group (PDR) (22 eyes).Aqueous humour and periphery blood samples were collected during the operation to detect MCP-1 and MIF using enzyme-linked immnunosorbent assay (ELISA).Written informed consent was obtained from each subject before any relevant medical examination.Results The average aqueous MCP-1 levels were(1660.78±562.98),(1463.26± 623.41),(686.76±186.16) and(494.35±148.59) ng/L in the PDR group,NPDR group,NDR group and control group,respectively,showing a significant difference among the 4 groups (F=37.968,P=0.000).No significant differences were found in the aqueous MCP-1 levels between the control group and NDR group (P=0.169),or between the NPDR group and PDR group (P=0.117).However,the aqueous MCP-1 levels were significantly elevated in the PDR group,NPDR group and NDR group compared with the control group (P=0.000).The average aqueous MIF levels were (6.85±1.99),(3.56±0.90),(1.10±0.48) and (0.86 ± 0.46) μg/L,respectively,with significant differences among them (F =144.502,P =0.000).Multiple comparisons between groups were found to be significantly different (P =0.000) according to the LSD-t test,except between the control group and NDR group (P =0.475).A significant positive correlation was seen between the aqueous MCP-1 level and MCP-1 level in all study participants (r =0.564,P =0.000).However,serum levels of MCP-1 and MIF were not statistically significantly different among the 4 groups (F =2.158,P＞0.05;F =0.813,P＞0.05).Conclusions The increase of the aqueous MIF and MCP-1 levels is associated with the progression of diabetic retinopathy.The results suggest that MIF and MCP-1 promote the occurrence of DR.

Objective To investigate the diagnostic value of double balloon endoscopy (DBE) in the elderly. Methods Clinical manifestations and endoscopic findings of 42 elderly patients (aged 60-80 years) and 73 young and middle-aged patients (aged 12-59 years) with small bowel lesions were obtained and compared. Factors influencing the diagnostic outcome of DBE in patients with small bowel bleeding were identified,and the optimal check time after the latest bleeding was determined.Results The procedures of 85.7％ (36/42) in the elderly and 79.5％(58/73) in young and middle aged were completed (P＞0.05).There was no significant difference in the procedure time between the two age groups.No severe complications were observed in the elderly group.The overall positive rate by double balloon enteroscopy examination were 71.4 ％ (30/42) and 63.0 ％ (46/73),respectively in the two groups (P＞ 0.05). Ulcer and tumor lesions were the most common findings,and diverticula and angiodysplasia were the second common findings. Longer duration of bleeding and higher number of bleeding episodes were found in the elderly with positive DBE findings than those with negative findings. Positive diagnostic rate was significantly higher when DBE was performed within 7 days than that after 7 days (90％ vs. 40％). Conclusions DBE is a safe,reliable diagnostic modality,especially in the elderly patients with small bowel bleeding in which ulcer and tumor lesions are the most common identifications.DBE is of greater benefit in patients with more bleeding episodes over a long period,and should be performed within 7 days after the last bleeding.

Objective To assess the value of pulmonary artery CT obstruction index for the evaluation of the severity of pulmonary embolism (PE),and to investigate the relation between pulmonary artery CT obstruction index and D-dimer levels.Methods 125 patients were diagnosed as PE by computed tomographic pulmonary angiography (CTPA)and D-dimer.Patients were separated into high-risk group and non-high risk group.CT obstruction index,D-dimer levels,diameter of the pulmonary artery were compared between two groups. Spearman’s rank correlation coefficients were used to assess the correlation between the CT obstruction index and the D-dimer levels,diameter of the pulmonary artery.Results CT congestion index of high-risk PE group was obviously higher than that of the non-high risk group (P=0.000).The diameter of pulmonary artery in high-risk PE group was obviously greater than that of the non-high risk group,the difference was statistically significant (P=0.000).No statistically significant difference was found in D-dimer levels between the two groups (P=0.103).There was no correction with CT congestion index and D-dimer levels(P=0.71).Conclusion The D-dimer levels of serum was a predictor of pulmonary embolism,cannot evaluate the severity of PE.CT obstruction index can reflect the severity of PE in some extent as an indicator of PE,there was no correlation with CT obstruction index and D-dimer levels.

OBJECTIVETo examine the differential levels of fecal Bifidobacterium, Bacteroides, Eubacterium rectale-Clostridium, Escherichia coli, Enterococcus, and Clostridium difficile between patients with hepatic cirrhosis and healthy controls. Fecal samples were collected from 29 patients with hepatic cirrhosis treated in the Department of Digestive Diseases at Zunyi Hospital between March and December of 2010.

METHODSFecal samples were collected from 13 healthy college students for use as controls. All samples were assessed by pH measurement, bacterial culture for turbidity, fluorescence in situ hybridization, and laser scanning confocal microscopy. The t-test and rank correlation test were used to determine statistical significance of intergroup differences in each tested parameter.

RESULTSThe feces of patients with hepatic cirrhosis had higher pH than that of healthy controls (6.79+/-0.64 vs. 6.18+/-0.74, P less than 0.05). The bacterial turbidity was not significantly different between the feces of hepatic cirrhosis patients and healthy controls (1.15+/-0.59 vs. 1.39+/-1.01, P more than 0.05). The numbers of Bifidobacterium, Bacteroides, Eubacterium rectale-Clostridium, Escherichia coli, Enterococcus, and Clostridium difficile in feces of patients with hepatic cirrhosis were significantly lower than those of the controls (all P less than 0.01). No significant correlation was found between the number or ratio of bacteria species and the severity of hepatic cirrhosis (Child-Pugh scores; P more than 0.05).

CONCLUSIONThe total quantity of intestinal bacteria in patients with hepatic cirrhosis is not significantly different from that in healthy patients. However, the profile of intestinal bacteria is different, which may explain the increased pH of fecal samples from patients with hepatic cirrhosis, but the differential profile is not correlated to cirrhosis pathogenesis.
