Objective To observe the effects of cisplatin on the expression of tumor stem cell markers in human hepatoma cell line HepG2 .Methods The cultured human hepatoma HepG2 cells in logarithmic growth phase were used for the study ,which were divided into control(no special treatment was administrated) and experimental groups(cisplatin was added) ,then the rates of cell growth inhibition ,transitional healing rates and changes in tumor associated markers associated P53 ,caspase‐3 ,caspase‐8 ,CD133 ,a‐denosine triphosphate‐binding cassette superfamily G member 2(ABCG2) ,intercellular cell adhesion molecule‐1(ICAM‐1) were measured .Results Comparison of cell growth inhibition :with the increase of drug concentration increased ,compared with the con‐trol group ,the difference was statistically significant(P<0 .05) .Transitional healing rate:with the increase of drug concentration , compared with the control group ,the difference was statistically significant(P< 0 .05) .The expression of related tumor markers P53 ,caspase‐3 ,caspase‐8 increased while the drug concentrations increase and were higher in the control group(P< 0 .05) ,the difference were statistically significant .In the immunofluorescence for the detection of CD133 ,ABCG2 ,ICAM‐1 ,the fluorescence in‐tensity increased with the concentrations of cisplatin .Conclusion Cisplatin could inhibit the growth of tumor cells by up‐regulating the tumor markers such as P53 ,caspase‐3 and caspase‐8 .The migration of tumor cells in cell scratch test could also be inhibited by cisplatin w hile their drug resistance w ere enhanced .

Objective:To investigate the efficacy of Hebert screw internal fixation of osteoporotic distal humeral coronary fractures in the elderly.Methods:A retrospective case series study was conducted to analyze the data of 26 elderly patients with osteoporotic distal humeral coronary fractures treated in Changhai Hospital from December 2011 to December 2018, including 3 males and 23 females aged 56-84 years (mean, 67.8 years). According to Bryan-Morrey classification, there were 7 patients with type I, 11 with type III, and 8 with type IV. All patients received open reduction and internal fixation. Among the 26 patients, 10 patients with simple humeral head fractures were treated with Hebert screw internal fixation, and 16 patients with humeral head fractures combined with humeral epicondyle fracture were treated with Hebert screw combined with humeral condyle miniplate. Operation time and intraoperative bleeding volume were recorded. At last follow-up, elbow range of motion were measured, and Mayo elbow performance score and visual analog scale (VAS) score were assessed. Meantime, complications were observed.Results:A total of 22 patients were followed up for 6-57 months (mean, 31.8 months). Intraoperative bleeding volume was 100 to 245 ml (mean, 126 ml) and operation time was 60 to 195 minutes (mean, 85 minutes). At last follow-up, the elbow joint flexion was (117.3±4.2)° and extension was (8.2±2.1)°. Mayo elbow performance score improved from preoperative 16.5 (12.8, 24.0)points to postoperative 85.0 (82.5, 92.3)points ( P<0.05). VAS was increased from preoperative (9.6±0.5)points to (2.3±0.2)points at latest follow-up( P<0.05). Two patients had elbow joint stiffness after operation and recovered after functional exercise. One patient had bone displacement when receiving rehabilitation care, which did not affect the function, and hence no further treatment was given. All patients had no infection or skin and soft tissue complications after surgery. Conclusions:For osteoporotic distal humeral coronary fractures in the elderly, Hebert screw internal fixation is effective in facilitating function recovery and relieving pain. When the fracture is combined with lateral humeral condyle fracture, additional plate fixation can be used for rigid stabilization.

Objective: To explore the efficacy of open reduction and internal fixation in the treatment of senile osteoporotic ankle fractures. Methods: A retrospective case series study was conducted to analyze the data of 26 elderly patients with osteoporotic ankle fractures which all caused by sprain from June 2012 to June 2018 in Changhai Hospital, including 10 male and 16 female patients aged from 60 to 93 years (mean, 69.72 years). In these 26 patients, three had medial malleolus fractures, four had lateral malleolus fractures, six had double ankle fractures and 13 had cotton's fractures. According to the Lauge-Hansen type, all 26 patients can be classified into four types: 5 with supination external rotation type, 4 supination adduction type, 16 with pronation-external rotation type and 1 with pronation abduction type. All the patients received open reduction and internal fixation. Plate fixation was used for lateral and posterior malleolus fractures, plate fixation and cannulated screws were applied to fix the comminuted posterior malleolus fracture while in the comminuted internal malleolus fracture, the steel plate was used only when needed. Early professional functional rehabilitation training and active anti-osteoporosis treatment were applied. All the operation time and bleeding volume were recorded, and the reduction of fracture plus the healing of wounds were observed. At last follow-up, American Orthopedic Foot & Ankle Society (AOFAS) Ankle Hindfoot Scale was used to evaluate the treatment effect and the Visual Analogue Scale (VAS)to evaluate the therapeutic effect and the subjective satisfaction of the patients. Complications were recorded as well. Results: All patients were followed up for 12-48 months (mean, 23.6 months). Operation time ranged from 30 to 95 minutes (mean, 70 minutes) and bleeding volume ranged from 10 to 150 ml (mean, 70 ml). All patients got satisfied reduction of fracture within 25 patients' incision healing in first intention, although one has fat liquefaction. AOFAS Ankle Hindfoot Scale improved from preoperative (84.4±10.8)points to (31.9±11.4)points at last follow-up (P<0.01), and the results were excellent in five patients, good in 17, fair in three and poor in one, with the excellent and good rate of 85%. VAS improved from preoperative(1.85±0.73)points to (9.23±0.28)points at last follow-up (P<0.01). Among 26 patients, 5 with ankle stiffness of different degree recovered after rehabilitation care, and 2 with internal malleolus fractures had bone displacement when receiving rehabilitation care, with no side effect on basic function. No serious complications such as wound infection or skin necrosis were found. Conclusion For osteoporotic ankle fractures in the elderly, open reduction and internal fixation can promote functional recovery and relieve pain.
