Objective To study the anatomic data of the first metatarsal dorsal artery and to provide anatomical basis for clinical tissue transplantation based on the first metatarsal dorsal artery.Methods The 16 adult cadaver specimens with 32 feet were dissected and meas-ured by vernier caliper.Then the anatomic data of the first metatarsal dorsal artery were analyzed.Results Through the examinations of 32 feet sample,the first metatarsal dorsal artery were classified into 5 types.Type Ⅰ:the first metatarsal dorsal artery runs at the surface of the first dorsal interosseous muscle (13 sides,40.6%).Type Ⅱ:the first metatarsal dorsal artery runs in the interior of the first dorsal interosse-ous muscle (11sides,34.4%).Type Ⅲ:the first metatarsal dorsal artery runs underneath the first dorsal interosseous muscle (6 sides, 18.8%).Type Ⅳ:the first metatarsal dorsal artery is slender (1 side,3.1%).TypeⅤ:the first metatarsal dorsal artery is absent (1 side, 3.1%).Distance relationship was measured between the first metatarsal bone and the first metatarsal dorsal artery:the vertical distance be-tween the origin of the posterior branch of the first metatarsal dorsal artery and base of the first metatarsal bone was (2.4 ±0.3)mm,the ver-tical distance between the origin of the posterior branch of the first metatarsal dorsal artery and head of the first metatarsal bone was (10.1 ±1.0)mm;the vertical distance between the origin of the anterior branch of the first metatarsal dorsal artery and the first metatarso-phalangeal joint was (7.6 ±2.7)mm.Conclusion The first metatarsal dorsal artery has clinical reference significance for the hands and feet’s trauma and skin flap transplantation such as thumb reconstruction.

OBJECTIVETo investigate the clinical effects of close reduction and minimally invasive percutaneous plate osteosynthesis in treating proximal humerus fractures in the aged.

METHODSFrom February 2012 to December 2013,39 patients with proximal humerus fractures were treated with minimally invasive percutaneous plate osteosynthesis (MIPPO group, 21 cases) and open reduction internal fixation (ORIF group, 18 cases). Including 17 males and 22 females in the study, and aged from 67 to 88 years old with an average of (71.8 ± 5.2) years old. In MIPPO group, there were 11 males and 10 females with an average age of (70.0 ± 5.3) years old;and in ORIF group, there were 10 males and 8 females with an average age of (72.0 ± 4.2) years old. Operation time, blood loss during operation, fracture healing time and postoperative complications were recorded. The functions of the shoulder joints were assessed according to Constant-Murley score at final follow-up.

RESULTSAll the patients were followed up from 11 to 27 months with an average of 18.1 months. The mean blood loss of the MIPPO group was (176.0 ± 57.4) ml,while the ORIF group was (356.0 ± 66.9) ml (t = 7.22,P = 0.01). The operation time of the MIPPO group was (47.4 ± 14.9) min, while the ORIF group was (92.7 ± 15.8) min (t = 0.79, P = 0.03). Fracture healing time in the MIPPO group and ORIF group was (17.6 ± 5.8), ( 21.7 ± 4.9) weeks, respectively (P < 0.05). The mean Constant-Murley score at final follow-up was 89.7 ± 14.5 in MIPPO group, and 81.8 ± 13.2 in ORIF group (P < 0.05).

CONCLUSIONMIPPO has advantages of little trauma, less blood loss, rapid recovery, less vascular damage and so on and can effectively treat the proximal humerus fracture in the aged.

Objective To determine the influence of gender on the association between serum uric acid and branchial-ankle pulse wave velocity (baPWV).Methods Cross-sectional data from 1418 adults who underwent routine laboratory tests and baPWV measurements were analyzed in a gender-specific manner.BaPWV≥ 1400 cm/s was defined as abnormality.The individuals were assigned to four groups (Q1,Q2,Q3 and Q4) according to the gender-specific quartiles of serum uric acid.The relationship between serum uric acid and the baPWV values was assessed by Spearman's correlation coefficients.In female,the relationship of serum uric acid quartiles with baPWV was evaluated by logistic regression analysis.Results In male and female,diastolic blood pressure,fasting blood glucose,triglyceride and body mass index were increased with serum uric acid level,in contrast to high-density lipoprotein cholesterol.The Spearman's correlation coefficient for the relationship between serum uric acid and baPWV was 0.18 in female and-0.05 in male (P =0.16).In female,univariate logistic regression analysis showed that in comparison with group Q1,odds ratio (OR) value of baPWV abnormality of group Q4 was 2.45 (95％confidence interval (CI) 1.48 to 4.06).In multivariate logistic regression,after adjusting for creatine and estimated glomerular filtration rate,OR value of baPWV abnormality of group Q4 was 2.45 (95％ CI 1.48 to 4.06) when compared with group Q1.However,after adjustment for age and other risk factors of cardiovascular diseases,there were no significant differents in ORs among serum uric acid quartile groups.Conclusions The association between serum uric acid level and baPWV in female may depend on age and metabolic syndrome components.

OBJECTIVETo discuss the efficacy of the myogenic elephant skin cream combining with VSD for treating severe bedsores.

METHODSTwenty-nine cases of III and IV degree bedsores were treated from June 2009 to June 2013. Among them, 15 cases were treated by myogenic elephant skin cream combined with VSD (VSD group) including 7 males and 8 females with an average age of (69.0±5.3) years old ranging from 17 to 96 years;other 14 cases were treated by the treatment of conventional dressing change (control group) including 6 males and 8 females with an average age of (71.0±4.2) years old ranging from 40 to 86 years. At 7, 14, 21, 28 d after treatments, specimens of wound two groups were respectively taken to examine immunohistochemical CD34 adopted SABC, the number of wild vascular cross were observed as capillary density value under high magnification microscope. It was used to assess the hyperplasia of granulation tissue of wound. The capillary density value and the visual wound observation were indicators for evaluation of clinical efficacy.

RESULTSSeventeen of 19 cases got complete data of specimens of wound at 7, 14, 21, 28 d,included 9 cases of VSD group,8 of control group. In the microscope view, the capillary density of VSD group was higher than that of control group significantly (P<0.05), it showed the application of VSD technology improved hyperplasia of granulation tissue much faster than conventional dressing change. In VSD group, 13 cases with 15 wounds healed, 2 cases with 3 wounds improved; in control group,3 cases with 3 wounds healed,7 cases with 9 wounds improved, 4 cases with 5 wounds were unhealed.

CONCLUSIONUsing the VSD technology with continuous high pressure suction to clean the drainage of wound and lacuna thoroughly can effectively control infection,promote the growth of granulation tissue, and then applying myogenic elephant skin cream to improve partial blood supply while prompting rapid growth of new granulation tissue and epithelial cell. The risk of this treatment is low,and the course of treatment is short, this provides a safe and effective method for treating bedsores.
