Objective To discuss methods of decoration reconstruction for finger defect in emergency and to observe the elinical effects.Methods Of the 41 cases of finger injuries of different degrees,15 were repaired with part of the skin flaps of the big toenails or skin flaps of the second toenalis,8 were repaired with part of the skin flaps of the big toenails,7 were reeonstructed with the second tiptoes,11 were repaired with the abdominal skin flaps of the big toes or lateral flaps of the second toes.Results All the 41 fingers sur- vived.One skin flap of the big toe was somewhat swelling and a decorating operation was performed.The 4～18 months of follow-up visitation of the rest cases revealed good function and shapes.No obvious functional ab- norality was found in the donating feet.Conclusion Various kinds of decoration reeonstruetion for finger defects are available to recover the hand shape and function as much as possible.

OBJECTIVETo summarize the epidemiological and biological features of triple-negative breast cancer (TNBC) and non-triple-negative breast cancer (non-TNBC) to provide reference for devising individualized therapy and making prognostic evaluation.

METHODSThe 5-year follow-up data were collected from 231 patients with pathologically established diagnosis of breast cancer treated in the Affiliated Hospital of Ningxia Medical University and Yinchuan People's Hospital between Jan. 2002 and Dec. 2004. The epidemiological and clinicopathological characteristics as well as the recurrence, metastasis and 5-year survival were compared between TNBC group and non-TNBC group.

RESULTSTNBC accounted 17.3% of the total breast cancer cases enrolled in this study. The tumor size and rates of recurrence and metastasis (especially visceral metastasis) were significantly greater in TNBC group than in non-TNBC group (P<0.05). The TNBC patients showed significantly lower 3- and 5-year survival rates than the non-TNBC patients (P<0.05), and TNBC patients with positive lymph nodes in clinical stage II had also a lower 5-year survival (P<0.05). Cox regression model analysis identified the patients' age, primary tumor size, clinical stages and triple-negativity as the independent risk factors for breast cancer.

CONCLUSIONCompared to non-TNBC patients, patients with TNBC have higher rates of local recurrence and invasion, visceral metastasis and poorer prognosis, and a lower rate of 5-year survival. The triple negativity represents an independent factor for prognosis evaluation of breast cancer.

OBJECTIVETo explore the expression of MICA/B in human esophageal cancer, and to analyze its correlation with clinicopathological features.

METHODSThe expression of MICA/B in 40 cases of esophagus carcinoma and corresponding normal esophageal mucosa tissues were examined by immunohistochemistry.

RESULTSThe positive rate of expression of MICA/B protein in the esophageal carcinoma was 75.0% (30/40), and that in the corresponding normal esophageal mucosa was 0 (0/40). Up-regulation of MICA/B expression was found in the esophageal carcinomas. The expression of MICA/B was related with histological grade of the esophageal carcinoma (P = 0.012).

CONCLUSIONMICA/B protein plays an important role in the esophageal carcinogenesis, and my become a useful molecular marker for the diagnosis of esophageal carcinoma.

OBJECTIVETo sort CD133(+) subset cells in human gastric cancer (GC) and to identify their tumor initiating cell-like properties.

METHODSThe tissues of GC and normal tissues adjacent to GC were obtained from 50 patients. Samples were stained for CD133 by immunohistochemistry. Likewise, assessments of CD133 were undertaken by Western blot. Flow cytometry was used to determine the proportion of CD133(+) cells in four GC cell lines therein the KATO-III was sorted by magnetic activated cell sorting (MACS) method. The growing characteristics and the tumorigenic ability of CD133(+) cells were evaluated in vitro and in vivo. Meanwhile, the growth of single cells in suspension culture was observed and expression of stem cell-specific marker were determined using reverse transcription-polymerase chain reaction (RT-PCR).

RESULTSThe expression of CD133 was demonstrated on the cell membranes in the mucosa and submucosa of primary GC, which were higher than those in the normal gastric tissues adjacent to cancer (P<0.05). Four GC cell lines including KATO-III, SGC-7901, AGS and MKN-45 were found to contain (28 ± 2)%, (17 ± 2)%, (6 ± 2)%, and (4 ± 2)% of CD133(+) cells respectively. In addition, the purity of CD133(+) cells isolated from KATO-III by MACS was (91 ± 3)% and up to(95 ± 2)% after 1-week culture. CCK-8 detection showed that population doubling time of the CD133(+) cells was (21 ± 3)h, significantly shorter than that of the CD133(-) cells[(40 ± 8)h, P<0.05]. Notably, there was a remarkable difference of tumor formation rate between CD133(+) cells (100%), non-sorted cells (80%), and CD133(-) cells(0). The average mass and volume of tumor in group of CD133(+) cells was larger and heavier than those in non-sorted cells (P<0.05, P<0.05). Furthermore, the single cell proliferated well, formed the big sphere and semi-quantitative RT-PCR showed expression of stem cell markers such as Oct-4, Nanog, Sox-2, Musashi-1 and EGFR.

CONCLUSIONSCD133 protein expression in primary lesions is higher than those in the normal gastric tissues. CD133(+) subset cells can be isolated, purified, and amplified in human GC, and possess some properties including the ability of self-renewal, proliferation, and higher tumorigenic ability in vivo and can express some stem cell markers.

OBJECTIVETo study the effect of human alpha-mannosidase Man2c1 transgene on tumor growth and metastasis in mice.

METHODSHepatoma cell H22 or squamous epithelial carcinoma cell S180 was subcutaneously inoculated into the right armpit of mice (wild type mice and 28#, 35#, and 54# transgenic mice). Tumor size was measured every week. Mice were sacrificed on day 9 or 10 and then the tumors were exercised and weighted. Tumors and lungs were fixed in formaldehyde and sectioned. The sections were stained with hematoxylin/eosin and examined under microscope. The red blood cells in spleen were destroyed by Tris-NH4Cl. Natural killer (NK) cell activity was detected with Yac-1 cell as target.

RESULTSH22 and S180 tumors grew faster in all the three transgenic mice (28#, 35#, and 54#) than in wild type mice. The average size and weight of tumors between the transgenic mice and wild type mice were significantly different (P<0.05). Most tumors in the transgenic mice invaded the surrounding tissues. In contrast, nearly all the tumors in wild type mice were capsulized. Three of 10 28# transgenic mice, 5 of 10 35# transgenic mice, 3 of 10 54# transgenic mice, and 1 of 10 wild type mice showed lung metastasis of H22 tumor. Two of 6 28# transgenic mice, 3 of 6 35# transgenic mice, 1 of 6 54# transgenic mice, and 0 of 6 wild type mice showed lung metastasis of S180 tumor. No difference of NK activity in spleen cells was observed between the transgenic mice and wild type mice.

CONCLUSIONShMan2c1 transgene promotes growth, invasion, and metastasis of transplanted H22 and S180 tumors in mice. hMan2cl transgene does not affect NK activity in splenocytes.

OBJECTIVETo introduce and evaluate the clinical effects of percutaneous reduction and Kirschner pin fixation for the treatment of intraarticular fractures of the calcaneus in children.

METHODSFrom March 2001 to February 2009,12 patients with intraarticular calcaneal fractures were treated by percutaneous reduction and Kirschner pin fixation (13 feet). There were 8 males and 4 females,ranging in age from 3 to 14,with an average of 8.7 years. According to Essex-Lopresti classification, among 5 feet were tongue fractures and 8 feet were compressed fractures. According to Sanders classification, 9 feet were type II and 4 feet were type III. The Biihler angle and Gissane angle of the calcaneus were obtained before and after operation. All patients were evaluated according to Maryland Foot Score.

RESULTSAll the patients were followed up for 16-71 months (means 35.9 months),and all the incisions were healed without complications and infection. The preoperative X-ray film showed that Böhler angle was (19.7+/-5.3) degrees, Gissane angle was (137.3+/-7.5) degrees. The postoperative X-ray film demonstrated that Böhler angle was (32.6+/-3.7) degrees, Gissane angle was (125.4+/-2.9) degrees. There was a significant difference between preoperative and postoperative (P<0.01). The average Maryland score was 96.3+/-2.4 (range, 92 to 100 points).

CONCLUSIONPercutaneous reduction and Kirschner pin fixation is an effective minimally invasive way to treat intraarticular fractures of the calcaneus in children, it has many advantages such as minimal invasion, reliable fixation and satisfactory effects.

OBJECTIVETo study the clinical effects of AO distal humerus plate (DHP) for the treatment of distal humeral fractures in elderly osteoporotic patients.

METHODSFrom September 2008 to January 2010, 18 elderly osteoporotic patients with distal humeral fractures were treated with open reduction and internal fixation with DHP. There were 3 males and 15 females, ranging in age from 62 to 83 years (averaged, 71.4 years). According to AO classification, 1 patient was Type A2, 3 patients were Type A3; 2 patients were Type B1, 2 patients were Type B2; 3 patients were Type C1, 4 patients were Type C2, 3 patients were Type C3. The surgical approaches were either bilateral or via olecranon process of ulna. Early mobilization was initiated after surgery. Functional results were evaluated according to the Mayo elbow performance score (MEPS).

RESULTSThe average duration of follow-up was 14.6 months (ranged from 11 to 24 months). All the patients had a complete healing of their fractures. There was no infection, hardware failure or loss of reduction after the operations. The average Mayo elbow performance score (MEPS) was (92.2 +/- 9.6) (65 to 100 points), among which the score of pain was (42.5 +/- 5.8) (30 to 45 points), the score of motion range was (19.2 +/- 1.9) (15 to 20 points), the score of stability was (9.2 +/- 1.9) (5 to 10 points), and the score of function was (21.4 +/- 2.9) (15 to 25 points). According to MEPS, 11 patients got excellent results, 5 good and 2 fair.

CONCLUSIONTreatment of distal humeral fractures in elderly osteoporotic patients with AO distal humeral plates can obtain immediate stabilization which facilitates early mobilization of the elbow.

OBJECTIVETo investigate the effects of effective components extracted from medicines compatibility on ischemic myocardial remodeling.

METHODThe animal models of ischemic myocardial remodeling was copied by ligating the left anterior descending branch of coronary artery in rat. And then decoction and effective components extracted from the same medicines were administrated to rats. The heart function was detected by ultrasound diagnostic apparatus and the heart morphology was examined by Hematoxylin and Eosin, picrosirius staining respectively on the 3rd and 56rd day.

RESULTBoth concentrated decoction and effective components compatibility showed good restrained effects on ventricle malignant remodeling, such as improved heart function, reduced the area of myocardial infarction, lowered heart index, mitigated the fibrosis level and decreased apoptosis cell numbers in infarction and non-infarction areas. The difference were statistically significant when compared with the control group (P < 0.01, P < 0.05), and effective components treated group had better effects than concentrated decoction group (P < 0.05). Concentrated decoction group showed little effects on the 3rd day, while effective components group showed significant effect (P < 0.05).

CONCLUSIONEffective components compatibility has better effects on inhibiting the process of ischemic myocardial remodeling than concentrated decoction. Effective components compatibility has better effects on ventricle malignant remodeling by eliminating the interfrence non-pharmacodynamic elements of the medicine.

OBJECTIVETo investigate the clinical efficacy of glucocorticoid combined with ulinastatin in the treatment of Kawasaki disease (KD) in children.

METHODSA total of 104 children who were admitted and diagnosed with typical KD between January 2011 and December 2013 were assigned to ulinastatin group (methylprednisolone+ulinastatin; n=46) and intravenous immunoglobulin (IVIG) group (n=58) according to the severity of KD and the willingness of their parents. Observations for the two groups were performed to compare the changes in coronary artery diameter before and at 1 week, 3 months, and 6 months after treatment, fever clearance time, retreatment condition, changes in white blood cells (WBC), platelets (PLT), hemoglobin (HB), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) at 1 week and 3 weeks after treatment, and total in-hospital cost.

RESYLTSThere was no significant difference in the coronary artery diameter between the two groups before or at 1 week, 3 months or 6 months after treatment (P>0.05). All the patients (100%) in the ulinastatin group vs 83% in the IVIG group had a normal body temperature after 48 hours of treatment (P<0.01). Two patients (4%) in the ulinastatin group and 10 patients (17%) in the IVIG group received retreatment. Significant differences were observed in ESR, WBC, and HB between them (P<0.01). The total in-hospital cost in the ulinastatin group was significantly lower than that in the IVIG group (P<0.01).

CONCLUSIONSFor children with KD, methylprednisolone combined with ulinastatin does not increase the risk of coronary artery aneurysm, decreases in-hospital costs, is superior in controlling laboratory markers and shortening the duration of fever during the acute phase compared with the IVIG therapy.
