Objective To investigate the treatment of combined subclavian artery and brachial plexus injury. Methods Since 1994, we have treated 5 cases of combined subclavian artery and brachial plexus injury. 2 of them were cut wound, 1 gun shot wound, and 2 blunt trauma. 2 cases had combined aneurysm and 1 had combined aneurysm plus A V fistula. According to the sites of subclavian artery injury, vein graft( 1 case) , suture repair( 1 cases) and ligation (1 case) were performed. The 2 cases of blunt trauma underwent only neurolysis because of masses of hematoma and tissue adhesion. Results The 3 cases of open injury who had underwent early repair of artery and nerve had various degrees of recovery of nerve functions and experienced no pain in the injured extremities. As for the 2 cases of blunt trauma, 1 got only pain relief and 1 had no recovery. Conclusion Dysfunction due to hematoma or progressive pseudoaneurysm compression on the brachial plexus can be relieved and patients can get maximal rehabilitation if hematoma or aneurysm is managed in time and the brachial plexus nerve is decompressed early.

Objective To analyze the relationship between daytime sleepiness and oxygen desaturation in the male eldcrly with obstructive sleep apnea /hyponea syndrome (OSAHS).Methods 147 male elderly (aged 60-80 years) with OSAHS in our sleep laboratory from March 2008 to February 2011 were divided into daytime sleepiness and daytime non-sleepiness groups. Epworth sleeping scale (ESS) and polysomnography (PSG) were employed to detect the degree of sleepiness.Oxygen desaturation were evaluated by oxygen desaturation index (ODI),average and minimum blood oxygen,time percentage of 90% oxygen desaturation (CT90). Resulls There were significant differences between the two groups in body mass index (BMI) (t=4.157),ODI (t=-10.063),average (t=5.800) and minimum (U=916) blood oxygen,CT90(U=887)and apnca/hypopneaindex (AHI) (t =-11.361) (all P<0.001).ESS scores were related with desaturation parameters of ODI,average and minimum blood oxygen and CT90 (r=0.683,-0.450,-0.583,0.507,all P<0.001).ODI was correlated with average and minimum blood oxygen and CT00 (r=-0.628,-0.763,0.689,all P<0.001).Among parameters of oxygen desaturation,only ODI had influence on ESS scores (odds ratio=1.11,95%CI:1.07 1.15),The sensitivity and specificity predicting daytime sleepiness at ODI ≥23 times/h were about 79.2% and 84.3%,respectively.Conclusions Daytime sleepiness is associated with oxygen desaturaion and may be predicted by ODI through which average and minimum blood oxygen and CT00 are related with daytime sleepiness in the male elderly with OSAHS.

Objective To explore the relationship between obstructive sleep apnea-hypopnea syndrome (OSAHS) and metabolic syndrome (MS) in obese middle-aged and older men. Methods We selectively recruited 154 obese middle-aged and older men matched for body mass index (BMI) and age. The polysomnography was performed for diagnosing OSAHS and for discriminating disease severity. The BMI, waist circumference, blood pressure, plasma glucose and lipid profiles were measured and analyzed in all subjects. Appropriate statistical methods were used to compare the components of MS in each group. Logistic regression was taken to elucidate the relationship between OSAHS and MS. Results Compared to control group, severe OSAHS group had significantly lower high density lipoprotein cholesterol level [( 1.03 ± 0.29 ) mmol/L vs. ( 1.31 ± 0. 38) mmol/L,P<0. 05] and higher fasting glucose [(6.61±1.76) mmol/L vs. (5.47±0.64) mmol/L, P<0. 05]as well as higher systolic blood pressure [( 133 ± 13) mm Hg vs. ( 125 ± 12) mm Hg, P<0. 05] and diastolic blood pressure [(99±10) mm Hg vs. (80±5) mm Hg, P<0. 05]. The prevalence of MS was significantly higher in OSAHS group than in control group (mild OSAHS group: 25.7%,moderate OSAHS group: 46. 5%, severe OSAHS group: 84.4%, control group: 16. 1 %, all P<0. 01). OSAHS was independently associated with an increased prevalence of MS Odds ratio, 6.16).Conclusions OSAHS is independently associated with MS in obese middle-aged and older men.

Objective To investigate the risk factors in association with congenital syphilis, in order to provide a basis for further improvement of the ongoing Prevention of Mother to Child Syphilis Transmis- sion Project in Shenzhen. Methods A nested case-control study was designed in neonates with risk of con- genital syphilis. The case group included 51 neonates with congenital syphilis, and the control group included 320 neonates without the disease. Results The risk factors in association with congenital syphilis were mother's age, residence, education level, weeks of gestation at time of starting standardized treatment,moth- er's TRUST titer at time of diagnosis; and also father's education level, occupation and history of multiple sex partners, as showed with univariate logistic regression analysis. After adjusted with multivariate uncondi- tional logistic regression analysis, 4 independent risk factors were found, namely, mother's age, father's edu- cation level, weeks of gestation at time of starting standardized treatment, and mother's TRUST titer at time of diagnosis. Conclusions Risk factors in association with congenital syphilis are identified, which provide important clues for effective prevention of congenital syphilis.

Background Stromal-derived factor 1α /chemokine receptor 4(SDF-1α/CXCR4) axis is one of the important signals which mediates several different activities such as chemotaxis,adhesion,proliferation and survival resulting in recruitment to sites of immune and inflammatory reactions.Considerable evidence suggests that CXCR4/SDF-1α axis is involved in tumor angiogenesis and plays a key role in the development of ocular neovascularization.Objective The purpose of this study was to explore the effect of CXCR4 antagonist on the development of cxperimental corneal neovascularization(CNV).Methods CNV model was established in the left eye of 8-weekold clean BALB/c mouse by putting the filter with 1 mol/L NaOH at the central cornea for 40 seconds.The animals were randomizcd into hyaluronate group and CXCR4 antagonist group,and the edydrops was topically administered respectively on the day of modeling 4 times per day for 14 days.CNV was examined under the slit lamp at the fourteenth day,and then the corneal suspension and section were made.Expressions of CXCR4 mRNA and protein in corneas were detected using RT-PCR and Western blot.The CD31 level in cornea was assayed by flowcytometry and immunochemistry.The expression of VEGF in burned corneas and suspension from mouse peritoneal macrophages stimulated with CXCR4 antagonist in vitro was detected by ELISA.The use of the animal followed Ragulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results Two weeks after corneal alkali burn,the growth of CNV peaked under the slit lamp.Compared with hyaluronate group,CNV was obviously decreased in the CXCR4 antagonist group.Immunochemistry showed that intensity of positive staining for CD31 in cornea in the CXCR4 antagonist group was weaker than the hyaluronate group.Flowcytometry clarified that CD31 positive cells rate was 9.50% ±2.34% in the CXCR4 antagonist group and 17.50% ±3.16% in the hyaluronate group,showing a significant difference between them (t=-7.312,P<0.05).In 2,4,7 days after cornea alkali burn,the expressions of CXCR4 mRNA and protein were significantly enhanced in burn corneas compared with normal corneas(P<0.01 ;P<0.05).ELISA showed that the VEGF expression level in corneal tissue and supernatant of mouse peritoneal macrophages in vitro were significantly lower in the CXCR4 antagonist group than that of hyaluronate group(t =10.927,5.151,P<0.05).The expression level of VEGF in corneal suspension was lower in the GM-CSH+CXCR4 antogonist group than that in the GM-CSH group (P<0.05).Conclusions CXCR4 antagonist can reduce experimental CNV by down-regulating VEGF expression in cornea.

Objective To explore a method for isolation and culture of human epidermal stem cells. Methods Epidermis was obtained by digesting human foreskin with Dispase Ⅱ and Trypsin-EDTA.After suspension on the epidermal stem cell medium (ESCM), these single epidermis cells were inoculated onto human collagen Ⅳ-coated flasks and cultured at 37 ℃ in a humidified atmosphere containing 5% CO_2 for 10 min. The nonadherent cells were rinsed off 10 min after inoculation, and the adherent cells continued to be cultured after enriching and abstraction by type Ⅳ collagen. The cell growth was observed through inverted microscope, and the cell cloning efficiency and time of clone sustain were also detected. Immunocytochemistry was used to observe the expression of ?_1-integrin and keratin 19(K19). Keratinocytes were served as controls. Results It was revealed by histological observation that colonies were formed 24 hours after inoculation. The isolated and cultured cell cloning efficiency was higher and the time of clone sustain was longer than that of the control group. Positive expression of ?_1-integrin and K19 of cultured cells was detected by immunocytochemistry. Conclusion Adult epidermal stem cells could be successfully isolated and cultured by adhension with type Ⅳ collagen and culture with ESCM.
