Cyclooxygenase-2 (COX-2) plays an important role in the development of leukemia.COX-2 inhibitor plays a certain anti-leukemia role in the process.Many studies show that COX-2 inhibitor plays antileukemia role by inhibiting the proliferation of leukemia cell,promoting apoptosis,affecting cell cycle,inhibiting cell metastasis and reversing cell drug resistance and so on.Therefore,the researches about the anti-leukemia mechanisms of COX-2 inhibitor will provide a new target in clinical prevention and treatment of leukemia.

Osteoporotic fracture is the most destructive ending of osteoporosis, many interacting risk factors play a role in its occurrence. With age, the bodies function decline gradually. Symptoms like soreness of the waist, back pain, cramp of the lower limb and weakness appears. These are related to TCM syndrome factors like kidney deficiency, liver deficiency, spleen deficiency and blood stagnation. Symptoms can act as a warning of the occurrence of osteoporotic fracture in the early stages. The risk assessment tool of osteoporotic fracture is mostly developed on the basis of modern risk factors and thus lacks syndrome differentiation, that may limit its utilization. If the relevant content of syndrome differentiation is integrated into the forecasting tool and a risk assessment tool of osteoporotic fracture which complies with the demographics of China is built up, population risk assessment for high of risk could be established and scientific evidence for the adoption of effective interventions could be applied.

OBJECTIVETo investigate the therapeutic effects of manipulative reduction for calcaneal fractures.

METHODSFrom January 2009 to June 2012, 53 cases (60 affected feet) of Sanders type I-IV calcaneal fractures were treated by manipulative reduction and external fixation with cardboard splint,including 45 males and 8 females with an average age of (33.5 +/- 1.54) years old ranging from 18 to 65. The course of disease ranged 0.5 h to 7 d. Before treatment the feet were swelling, ache and activity limitation in evidence, some feet were wide flat deformity, the cortical bone was broken in the imaging examination. All selected cases were evaluated using Creighton-Nebraska health foundation assessment scale for fractures of calcaneus.

RESULTSAll cases were followed up at 12 months after treatment, 13 feet got excellent curative effect, 34 good, 11 moderate and 2 poor.

CONCLUSIONManipulative reduction for Sanders type I-IV calcaneal fractures could get excellent curative effect. Manipulative reduction for calcaneal fractures could avoid surgical trauma while assure high curative effects. Manipulative reduction is not only economical and easy therapy, but also can restore maximum function of the calcaneus with few complications and facilitate early rehabilitation of ankle and joint function.

Objective To assess the benefit of intraoperatively placed nasointestinal feeding tubes for early postoperative enteral nutrition.Methods The retrospective study was carried out on 19 cases of in-fants with long gap esophageal atresia who underwent one-stage operation in Xinhua Hospital from January 2006 to December 2013.Patients were divided into two groups according to whether the transanastomotic na-sointestinal feeding tubes(TNFT)were placed.Demographics,associated anomalies,operative findings,com-plications,duration of enteral nutrition(EN),length of stay were analyzed.Results Thirty-seven patients had long gap esophageal atresia and nineteen underwent one-stage operation.Eight patients were identified as TNFT group while eleven patients were identified as nonfeeding tube(NFT)group.There was no significant differences between the two groups in gestational age,birth weight,associated anomalies,anastomotic leak, weight gain,ICU-free days and length of stay(P>0.05).But the ventilator-free days(23.5 d vs.19.3 d), first EN time(0.8 d vs.9.1 d)and total EN feeding time(15.9 d vs.21.4 d)between the two groups were significantly different(P<0.05 ).Conclusion Intraoperatively placed TNFT may lead to earlier EN feeding and shorter parenteral nutrition duration,but a larger prospective study would be required to prove the benefits and ensure the safety.

ObjectiveTo explore a procedure to correct the multiple facial deformities by using the expanded frontal flap combined with the axial flaps.MethodsAccording to the face deformity we used the rectangle 100-350 ml expanders behind the frontal hairline,after finishing the tissue expanding,adopted two or three axial flaps based on the supraoribital,supratrochlear or temporal vessels. ResultsA total of 13 cases were treated with this approach.7 eases were nose and lip defect reconstruction after burn,in which temporal vessel-based flap was used in 2 cases and supraoribital or supratrochlear vessel-based flaps in 5 cases.The other 6 cases were nasal reconstruction combined with the frontal defect correction by using random flaps,including 2 cases of pigmented nevus,1 neurofibroma,and 3 burn scars.All the flaps survived and satisfactory appearance was obtained.Conclusions The expanded frontal flap combined with axial flap based on multiple vessels is a good approach to correct the multiple facial deformities.

The Hedgehog (Hh) signaling pathway plays a key role in the embryonic development, which is formed by the Hedgehog(Hh) , membrane-receptor complex Patched (Ptch) and Smoothened (Smo), multifunctional transcription factors Glioma-associated oncogene homolog (Gli) and other signal molecules. The Hh signaling pathway controls a variety of developing processes, however, no or less expression is observed in the normal pancreas tissues.The mutational activation of the Hh signaling pathway is associated with tumorigenesis and metastasis of the pancreatic cancer. The aim of this review is to present a brief overview of the Hedgehog signaling pathway in the mechanism of the tumorigenesis of the pancreatic cancer.

Objective To explore the mechanism of aluminum-induced damage of learning and memory by studying the change of calcium-calmodulin-dependent protein kinase Ⅱ(CaMKⅡ) in the hippocampus of lactational rats. Methods Three groups of clean pregnant Wistar rats (120-200 g) were randomly divided into 3 groups. On the first day of parturition, the dams of two groups were given 0.3% and 0.6% AlCl3 through drinking water and terminated on the weaning day (21 days). Western blot was used to determine the content and activity of ?-CaMKⅡ. Results The aluminum levels in the blood and brain of aluminum-treated rats were obviously higher than that in the control (P

In the past two decades,with the development of electron optics,computer and imaging,hip arthroscopy surgery has become the best effective method in the diagnosis and treatment of the hip discord,as a method integrates less invasive and invisible characteristics.The indication of hip arthroscopy gradually expands and has become the gold standard in the diagnosis and therapy of hip discord.Recent research shows hip arthroscopy can provide early diagnosis and treatment hip unexplained pain,such as femoroacetabular impingement(FAI),labral tears,chondral lesions,furthmore hip arthroscopy shows good prospects in the treatment avascular necrosis of femoral head,synovial abnormalities,post hip arthroplasty discomfort.
