OBJECTIVETo explore clinical effects of digital artery bilobed flap for the treatment of skin degloving injury of thumb.

METHODSFrom January 2007 to December 2012, 45 patients with skin degloving injury of thumb were treated with grafting of digital artery bilobed flap. There were 39 males and 6 females, ranging in age from 19 to 46 years, with an average of 32 years. The disease course ranged from 0.5 to 15 h. Eighteen patients suffered from defect of palmar skin above nail root and nail bed, 19 patients suffered from skin degloving injury of thumb phalangette, and 8 patients had whole skin degloving injury of thumb. The double lobe flaps were designed at the ulnar side of middle finger and the radial side of ring finger according to the defect of thumb skin. The arteria digitalis communis between the middle and ring fingers and its two branches of arteriae digitales propriae supplying the two fingers were used as a vessel pedicle. The flap with digitales proprii nervi was transposed and used to cover the exposed phalanx of thumb. Full thickness graft was used for the donor site. Observation of the appearance, texture, color and wear resistance of flap, appearance, color and depression of grafting area, skin feeling, and finger activities was conducted.

RESULTSAll the flaps and grafts were alive. Forty-three patients were followed up with an average duration of 25 months, and two patients lost follow-up. The color and texture of the flaps were similar to that of the contralateral thumb pulp. The average two point discrimination was 4.2 +/- 0.3 mm. The color of graft skin was slightly deeper than that of the surroundings skin.

CONCLUSIONDigital artery bilobed flap graft is an effective and ideal operation, which is of low risk and high success rates for skin degloving injury of thumb.

AlM: To study clinical reference value of retinal microvascular changes in patients with cerebral microbleeds ( CMBs) and discuss its clinical significance.
METHODS:From January 2012 to December 2013, 125 hospitalized patients were collected, including 81 cases were male, 44 cases were female, mean age 76. 3 ± 11. 2 years old. For all patients, functions of liver and kidney, blood - lipoids, blood sugar and blood biochemical examination were tested, and fundus photography and cerebral MR was done. According to the fundus camera eyes, retinal arteriolar equivalent ( RAE) , retinal venular equivalent ( RVE) , retinal vein diameter ratio ( AVR) and arteriovenous crossing sign ( AVN ) were identified, CMBs were classified with cerebral MRl. All the data were processed by SPSS statistical software.
RESULTS: The central retinal arteriolar equivalent (CRAE), central retinal venular equivalent (CRVE) and AVR values in the eyes were found no statistical difference (P<0. 05). Of CMBs classification, the grade 0 in 75 cases, 1 in 27 cases, 2 in 9 cases and 3 in 14 cases were included. The RVE, AVR and AVN and the different grades of CMBs had statistically significant correlation ( P<0. 01). The higher CMBs classification, the more obvious retinal microvascular changes were found. ln respectively to eliminate risk factors such as age, sex, blood glucose and blood pressure, AVR and AVN were still influencing factors for CMBs classification.
COCLUSlON: The results show that retinal microvascular changes, especially small retinal vein arteriovenous cross width, and arteriovenous crossing phenomenon, in which CMBs will happen more likely. After sex, age, hypertension and hyperglycemia in patients with traditional cardiovascular risk factors being ruled out, the retinal microvascular changes are still relatively factors of CMB's occurrence.

OBJECTIVETo discuss the treatment of the windblow hand deformity.

METHODSWe treat 18 patients with operations step by step. First phase: to improve the thumb function; Second phase: shift the flexor digitorum superficialis of the middle and little finger to improve the ulnar drift of the digits; Third phase : to solve the flection deformity of the palm and digits.

RESULTSWe follow the patients for 6 - 72 months, only lost 3.11 of 15 patients have the thumb function recovered. 9 patients had their ulnar drift of the digits corrected, 2 patients partly corrected, 4 have relapse. 5 among the 15 patients were offered second operation, to have the ulnar arthrosis bursa contracted, using abduction splint, after rehabilitation 4 patients have the deformity corrected, 1 has partly corrected.

CONCLUSIONSOperation step by step is better for the complex windblow hand deformity, solve one major problem each time,and systemic rehabilitation therapy is needed for satisfied curative effect.

OBJECTIVETo examine granulocyte colony stimulating factor (G-CSF) expression in human non-small cell lung cancer (NSCLC) as well as discuss its clinicopathological significance.

METHODSSpecimens were obtained from 114 cases (53 cases with granulocyte infiltration) diagnosed pathologically as NSCLC in General Hospital of PLA. Paraffin-embedded tissues from these 114 cases of NSCLC were examined for expression of G-CSF by immunohistochemical staining. Correlation between G-CSF expression and pathological features, clinical manifestation, prognosis of patients with NSCLC was analyzed statistically. All the patients were retrospectively followed-up.

RESULTSFifty-five of the 114 NSCLC specimens expressed G-CSF, and among these 41 (41/54, 75.9%) were large cell carcinoma, nine (9/30, 30.0%) were adenocarcinoma and five (5/30, 16.7%) were squamous cell carcinoma. The expression was significantly correlated with infiltration of tumor mass by neutrophilic granulocytes, histological type, necrosis, differentiation, lymph node metastases, distant metastases, recurrence and survival period (P < 0.01). There was no significant correlation with primary tumor size (P > 0.05). Logistic multi-factor analysis revealed that necrosis, lymph nodes metastases and distant metastases RR (risk ratio) in G-CSF positive group was 5.57, 6.28 and 5.24 times higher than those of G-CSF negative group (P < 0.05). There were remarkable difference of 5-year survival rates (0 and 12.1% respectively) and survival period (42 and 62 months respectively) between positive and negative groups (P < 0.01).

CONCLUSIONSNSCLC with G-CSF excretion are mainly large cell lung cancer. The pathologic characteristics of these cases with G-CSF expression included poor differentiation, remarkable atypia, prominent necrosis and infiltration of tumor mass by neutrophils or emperipolesis. These tumors are usually more aggressive in biological behavior and have worse prognosis than those without G-CSF expression.

Diabetes has become the third largest killer to human life and health,and its development is closely related to the intestinal flora imbalance caused by series of consequences.So adjusting the structure of intestinal flora becomes a new idea for the treatment of diabetes.Traditional Chinese medicine (TCM) has good curative effect in prevention and treatment of diabetes,and improvement on the structure of intestinal flora may be one of its important mechanisms.The article reviewed the research progress on prevention and treatment of diabetes by TCM single components (berberine,phloridzin,rheinic acid,etc),TCM single prescription (essential oil from Cinnamomum cassia,flower stalk of Coptis chinensis,total coumarin of Feucedani Radix) and TCM priscriptions (Gegen Qinlian Decoction,Shengjiang Powder,Buzhong Yiqi Decoction,Huanglian Jiedu Decoction,Wenyang Yiqi Huoxue Compound,etc.) based on new targets in intestinal flora,so as to provide reference for the development of TCM for prevention and treatment of diabetes.

Objective To investigate the influence of body mass index(BMI) on the prognosis of patients who had received elective PCI.Methods The study population consisted of 2964 consecutive patients with electivePCIs performed between July 2009 and September 2011. The patients were divided into three groups based on their preoperative BMI levels:the normal group( BMI<24.0 kg/m2,n=810); the overweight group( 24.0 kg/m2≤BMI<28.0 kg/m2,n=1454) and the obese group(BMI≥28.0 kg/m2,n=700). We examined the association between baseline BMI levels and postoperative mortality through a mean(571.5±130.8)days of follow up.Results Patients with high BMI had a higher percentage of comorbidities compared with the normal BMI group. The results of multivariate Cox regression analysis revealed that preoperative BMI was inversely associated with mortality after adjustment for other factors (HR 0.896,95％ CI 0.821-0.977,P=0.031). Compared with the obese group, the hazard ratios for risk of mortality in the overweight and the normal groups were 1.908(95％CI 0.689-5.291,P=0.213) and 2.241(95％CI 1.154-4.350,P=0.017).Conclusions For patients undergoing elective PCI, individuals with obesity and overweight had the better prognosis than those with normal BMI.

BACKGROUNDCoronary slow flow phenomenon (CSFP) is an important, angiographic clinical entity but is lacking non-invasive detecting techniques. This study aimed to elucidate the value of transthoracic Doppler echocardiography (TTDE) in the diagnosis and monitoring of coronary slow flow in left anterior descending (LAD) coronary artery.

METHODSWe consecutively enrolled 27 patients with CSFP in LAD detected by coronary arteriography from August 2009 to April 2010. Thirty-eight patients with angiographically normal coronary flow served as control. Corrected thrombolysis in myocardial infarction (TIMI) frame count (CTFC) was used to document coronary flow velocities. All subjects underwent TTDE within 24 hours after coronary angiography. LAD flow was detected and the coronary diastolic peak velocities (DPV) and diastolic mean velocities (DMV) were calculated.

RESULTSSixty of 65 (92.3%) subjects successfully underwent TTDE. Baseline clinical characteristics were similar between the two groups. Coronary DPV and DMV of LAD were significantly lower in the CSFP group than in the control group ((0.228 ± 0.029) m/s vs. (0.302 ± 0.065) m/s, P = 0.000; (0.176 ± 0.028) m/s vs. (0.226 ± 0.052) m/s, P = 0.000, respectively). There was a high inverse correlation between CTFC and coronary DPV and DMV (r = -0.727, P = 0.000; r = -0.671, P = 0.000, respectively). Receiver operating characteristic (ROC) curve showed that the area under the curve (AUC) was less than one half for coronary DPV (AUC = 0.104) and DMV (AUC = 0.204), respectively.

CONCLUSIONSIn patients with CSFP, there is a high inverse correlation between CTFC and coronary diastolic flow velocities in the LAD coronary artery, as measured by TTDE. The value of TTDE in the monitoring and evaluation of coronary flow in patients with CSFP deserves further investigation.
