In order to obtain experimental evidences of therapeutic effect of rhIL 11 for clinical use, we observed the effects of rhIL 11 on colony formation of multilineage human hematopoietic cells in vitro and acceleration of platelet count and bone marrow hematopoietic recovery in 3 0Gy ? ray irradiated rhesus monkeys. The results showed that rhIL 11 significantly increased the nadirs of PLT count and shortened the duration of PLT numbers below 50% of their baseline values. The recovery of PLT in irradiated monkeys was accelerated. Dosage related PLT recovery was not observed. rhIL 11 not only promoted the proliferation and maturation of CFU Mk but also improved the proliferation of CFU GM, CFU e, BFU e and CFU Mix. These data suggest that rhIL 11 may be an effective agent in the treatment of hemopoietic suppression and thrombocytopenia.

Objective To investigate the operative treatment of displaced intra-articular fractures of the calcaneus using a small lateral incision approach.Methods Thirty-one patients with 32 intra-articular calcaneal fractures,were treated with open reduction and internal fixation through a small lateral incision approach from October 2004 to April 2006.The skin incision was made from the distal tip of the fibula to the base of the fourth metatarsal.According to Sanders classification,there were 21 typeⅡfractures and 11 typeⅢfractures.The first change of dressing was done on the second day after operation.The residual blood clots in the wounds were cleaned as much as possible when the drainage sheet was removed.The operated foot was bandaged with pressure dressing of cotton pad.Results After an average follow-up of 10.5 months(range,3 to 18 months),no soft tissue com- plications were found,and all had acceptable reduction.The preoperative X-ray film showed that B(?)hler angle was 6.84??9.36?,Gissane angle was 106.04??12.03?.The postoperative X-ray film demonstrated that B(?)hler angle was 32.06?+6.87?,Gissane angle was 115.81??9.48?,and the difference was statistically significant(P＜0.01).According to the AOFAS evaluation system for Ankle-Hindfoot,two feet scored 60-70 points,nine feet 70-80 points,16 feet 80-90 points and five feet 90-100 points.Condusion The small lateral incision approach is a good option for management of calcaneus fractures,because it causes minimal soft tissue damage,provides excellent exposure,and leads to convenience for later removal of internal fixators and subtalar arthrodesis.

Remaining organic and functional damage of ischemia cardio-cerebrovascular disease is always a main trouble puzzling the clinicians. After the discovery of endothelial progenitor cells (EPCs), researchers realize that postnatal angiogenesis is an important biological process, which play a key role to repair the ischemia tissue and improve the function. So a new concept which names therapeutic angiogenesis supply a new treament way for the ischemia cardio-cerebrovascular disease. Traditional Chinese medicine (TCM) has accumulated rich experience on treating the ischemia disease, studies found that many Chinese medicine prescriptions and effective ingredients can increase the therapeutic angiogenesis, howerer the mechanisms were not the same, they mainly manifest in regular the secretion of angiogenic factors, increase the proliferation and differentiation etc. In this paper, we review recent studies, summary the Chinese medicine prescriptions and effective ingredients which can increase the therapeutic angiogenesis, and analyze the differernt pathway. We view to provide reference for the later researchers.

Objective To explore the efficacy difference of biliary stent combined with 125I seed intracavity irradiation and palliative biliary drainage in the treatment of obstructive jaundice caused by pancreatic head cancer. Methods The clinic date of 95 patients with pancreatic head cancer who underwent palliative surgery from June 2010 to June 2015 were analyzed retrospectively. 46 of the cases were treated with percutaneous biliary metal stent implantation combined with 125I seed intracavity irradiation (stent group), and the other 49 cases were treated with palliative biliary enterostomy (surgery group). The levels of jaundice, liver function, tumor size, survival time and hospitalization cost were compared between the patients before and after treatment. Paired t-test was applied for statistical analysis. Results Both the two treatment coulel effectively relieve jaundice and improve liver function. The mean TBIL of surgery group and stent group was (29.4±9.6) and (21.0±8.0)μmol/L after three months treanment, (40.3±11.0) and (24.4±9.6)μmol/L after six months treatment, respectively. Tumor maximum diameter of the two groups were (37.9 ± 4.5) mm and (33.5 ± 6.0)mm after three months treatment, (45.9 ± 5.0) mm and (37.0 ± 6.5) mm after six months, respectively. Each time point between them had statistical significance (t=-4.235,-5.476,-3.654,-6.702, P<0.05). The mean survival time was (12.83 ± 0.80) months in the stent group and (9.06±0.49) months in the surgery group, the difference was statistically significant (t=-3.49, P<0.01). The mean hospitalization cost of the stent group was (38 453.0 ± 7 282.0) yuan and the surgery group was (43 057.0 ± 7 667.4) yuan, the difference was statistically significant (t= 2.759, P<0.05). Conclusion For inoperable pancreatic head cancer patients, compared with palliative biliary enteric drainage, percutaneous biliary stent placement combined with 125I seed intracavity irradiation can effectively relieve biliary obstruction, improve liver function, inhibit tumor growth and prolong survival time.

Objective To investigate the application value of pancreatic duct guide wire and transpancreatic septotomy with precutting technique in difficult endoscopic retrograde cholangiopancreatography.Method258 patients who underwent difficult endoscopic retrograde cholangiopancreatography from April 2014 to April 2016 were selected as study subject, 128 patients among them received the technique of pancreatic duct guide wire, the other 130 patients received transpancreatic septotomy with precutting techniques. The success rate, intubation time and incidence of complications were compared between these two methods for cannulation.Result There was no signiifcant difference in preoperative clinical data between the two groups, the success rate did not differ signiifcantly between the two groups (93.75 % vs 93.85 %). Compared with transpancreatic septotomy with precutting techniques group, pancreatic duct guide wire group is less intubation time consuming (5.92 ± 0.69 vs 12.81 ± 3.67) min, the difference was statistically significant (t = -2.27,P < 0.05). 25 patients experienced complications, with 6 cases of acute pancreatitis, 2 cases of biliray tract infection in pancreatic duct guide wire group, and 8 cases of acute pancreatitis, 3 cases of hemorrhage,6 cases of biliray tract infection in transpancreatic septotomy with precutting techniques group. The pancreatic duct guide wire group had a signiifcantly lower incidence of complications (6.25 % vs 13.08 %). the difference was statistically signiifcant (χ2 = 3.27,P < 0.05). The incidence of acute pancreatitis did not differ signiifcantly between the two groups (4.69 % vs 6.15 %).ConclusionsPancreatic duct guide wire and transpancreatic septotomy with precutting techniques both can further improve the success rate of bile duct cannulation with ERCP. The incidence of acute pancreatitis did not differ significantly between two groups. But pancreatic duct guide wire group is less intubation time consuming, and had a significantly lower incidence of complications. Because of the convenience and safety of the pancreatic duct guide wire technique, and the insertion of the pancreatic duct does not increase the risk of postoperative acute pancreatitis. We think that this method is more worthy of Clinical promotion.

Objective To investigate the expression of Notchl and NUMB in gastric cancer and explore the relationship between two genes and clinicopathologic features. Methods The mRNA and protein expressions of Notchl and NUMB in the gastric cancer tissues and normal gastric tissues were determined by realtime PCR and Western blotting. Results The mRNA expression of Notchl in gastric cancer tissues was 1.67times that of Notchl in normal gastric tissues. The increase of the mRNA expression of Notchl was correlated with tumor differentiation and lymph node metastatis of the patients ( P < 0. 05 ). The mRNA expression of NUMB in gastric cancer tissues was 0.597 times that of Notchl in normal tissues. The decrease of the mRNA expression of NUMB was correlated with tumor differentiation of the patients (P < 0.05). The expression of Notchl was negatively correlated to that of NUMB ( r = - 0.459, P < 0.05 ). The protein expression of Notchl in gastric cancer tissues was (0. 348 ±0. 133) , which was significantly higher than (0. 208 ±0. 140) in normal gastric tissues (P < 0.05 ). The protein expression of NUMB in gastric cancer tissues was (0.490 ±0.440), which was significantly lower than 0.746 ±0.390 in normal gastric tissues (P<0.05).Conclusion Up-regulation of Notchl and down-regulation of NUMB may play an important role in the occurrence and development of gastric cancer.

Purpose To investigate the CT gemstone spectral imaging features of gastric stromal tumors (GST), so as to discuss the value of CT gemstone spectral imaging in the diagnosis and differential diagnosis of GST. Materials and Methods Thirty patients with GST proved pathologically were scanned by gemstone spectral imaging. Their GSI scanning image data and the related clinical data were retrospectively analyzed, and the quantitative analysis based on iodine content of the lesions in both arterial phase and portal phase was carried out. Results The GSI findings showed that the lesions were intra-luminal, extra-luminal or both intra-and extra-luminal soft tissue mass, the sizes were various, and they protruded either toward the inner side of stomach or the opposite or both. Among them, the diameter of 4 tumors in the low risk group ranged from 1 to 5 cm; in the intermediate risk group, 3 tumors had diameters from 1 to 5 cm, and 3 others were from 6 to 19 cm; in high-risk group, 18 tumors' diameter were between 6 to 9 cm, 2 were between 1 to 5 cm, and the rest 1 had multiple lesions in various sizes. Fifteen tumors occurred in gastric body, 10 occurred in gastric antrum, 4 were at the bottom of the stomach, and 1 had multifocal growth. Sixteen patients had internal and external growth of lesions, among whom 14 patients were at high risk; 10 patients' lesions were outside the cavity, including 6 patients at high risk and 1 patient at low risk; and 4 patients had lesions inside the cavity, including 3 patients at low risk. At the arterial phase the foci mildly strengthened, and they strengthened increasingly at the portal phase. The material value based water and iodine figure showed that material value based iodine of the lesions at both arterial phase and portal phase was higher than that in the normal gastric wall tissue, and the material value based iodine of the lesions at portal phase was higher than that at arterial phase (F=378.6 and 296.6, P<0.05). At arterial phase, the iodine content of the lesions in the mucosa was slightly higher than that in the submucosa and muscular layer (t= - 2.245, P<0.05). Conclusion CT gemstone spectral imaging can accurately show the external forms and internal changes of GST lesions and iodine content measurement can provide quantitative diagnostic information, therefore they can provide more effective information for clinical diagnosis.

Objective To investigate the clinical characteristics of aerophagia in children,and to evaluate the effect of 24 hours esophageal multichannel intraluminal impedance monitoring in diagnosis of aerophagia.Methods The clinical data of 30 children with aerophagia hospitalized in Department of Digestive Disease,Nanjing Children's Hospital Affiliated to Nanjing Medical University from July 2005 to June 2013 were reviewed.The 24 hours esophageal multichannel intraluminal impedance monitoring was performed in 8 cases of aerophagia.The treatment of these patients normally included psychological counseling,dietary adjustment,Iactulose,Domperidone and vitamins,while Simethicone was given to the patients if normal treatment was invalid.Results Of the 30 patients,aged 2 to 13 years,averaged (8.6 ± 4.5) years,the chief complaints were abdominal distention in 30 cases (100.00％),visible or audible air swallowing in 28 cases (93.33％),repetitive belching in 27 cases (90.00％),reduced appetite in 25 cases (83.33％),constipation in 22 cases (73.33％),psychological stresses in 15 cases (50.00％),recurrent abdominal pain syndrome in 10 cases(33.33％),chronic diarrhea in 3 cases(10.00％) and acute abdominal pain in 3 cases(10.00％).Among the 30 patients,24 hours esophageal multichannel intraluminal impedance monitoring was performed in 8 cases,averaging 149.63 (47-553)times of air swallowing were recorded.In the 30 patients,24 cases (80.00％) were relieved after being treated with psychological counseling,dietary adjustment,lactulose,domperidone and vitamins,and only 6 cases(20.00％) were invalid for normal treatment but well responeded to Simethicone.Conclusions Aerophagia is a kind of functional gastrointestinal disorders in children.Abdominal distention,air swallowing,repetitive belching,reduced appetite,constipation and pain are common symptoms.It can be cured through psychological counseling management,diet modification,laxatives,propulsives and vitamins.24 hours esophageal multichannel intraluminal impedance monitoring is a useful technology in the diagnosis of aerophagia children.

Objective To investigate indications,technique,prognosis and complications of anterior flap hemipelvectomy (hemipelvectomy using a quadriceps femoris muscle flap with superficial femoral artery)in the treatment of pelvic tumors.Methods From April 2009 to October 2010,10 patients with pelvic tumors underwent anterior flap hemipelvectomy in our department.There were 9 males and 1 female,aged from 30 to 62 years (average,46 years).There were 7 cases of chondrosarcoma,1 case of epithelioid sarcoma,1 case of pleomorphic liposarcoma and 1 case of spindle cell sarcoma.Results Nine patients were followed up for 12 to 30 months (average,21.5 months).Superficial skin necrosis occurred in 1 patient,while there was no wound infection.Local recurrence (33.3％) occurred in 3 patients,including 2 cases of chondrosarcoma and 1 case of epithelioid sarcoma.Three patients died at last,including 2 patients with local recurrence and 1 with pulmonary metastasis from liposarcoma.Two patients survived with pulmonary metastasis,and remaining 3 patients survived without recurrence and metastasis.Conclusion Anterior flap hemipelvectomy is indicated for:(1) patients with extensive soft tissue sarcoma in the buttock,and the tumor or reaction zone involve the subcutaneous tissue; (2) patients with recurrent pelvic tumors,and the conventional posterior flap can't be used due to contamination by the original incision; (3) patients whose posterior flap has poor blood supply due to radiotherapy or other factors.The prerequisite of the surgery is that the blood stream between external iliac artery and femoral artery is unobstructed; moreover the blood vessels are not in the tumor reaction zone.Compared with conventional posterior flap,the anterior flap hemipelvectomy is an easier procedure,which not only can easily cover surgical defect and obtain better surgical margin,but also has less complications.
