Conclusion There is an excess activation of cytokines in T2DM,which is significantly correlated with insulin resistance. Cytokines play the important role in the occurrence and development of T2DM and insulin resistance.

Objective There are many methods to treat adult humeral shaft fracture. Plates fixation and intramedullary locking nail are two important methods. Though plate fixation are "gold criterion", there were many defects limited its development. With humeral intramedullary nail widely used, this study is to analysis and investigates the complications of locked nailing in humeral shaft fractures. Methods Between January 2000 and January 2004, 90 humeral shaft fractures (74 acute fractures and 16 delayed unions or nonunions) in 89 patients were treated with humeral intramedullary locking nails and followed up for an average of 25.4 months(12-34 months). There were 56 males and 33 females, with an average age of 39.3 years. Acute fractures included 62 closed, 7 Gustilo type Ⅰ, 3 type Ⅱ and 2 type Ⅲa open fractures. 12 nonunions had previous operations. 8 patients had radial nerve palsy. In general, acute fractures were treated with closed nailing and nonunions were treated with open nailing with bone grafting. 53 proximal humeral fracture were treated by antegrade nail, the others with distal humeral fracture were treated by retrograde nail. Results In total, 17 patients had 18 significant complications. 5 of them were persistent nonunions. There was no statistics difference between antegrade nail and retrograde nail. The others were protruded screws, fracture gap, shoulder impairment, elbow impairment, angular malunion, deep infection and postnailing radial nerve palsy. Conclusion The risk of operative comminution was significantly higher in retrograde nailing, and operative comminution resulted in a significantly higher risk of nonunion. Many complications of humeral locked nailing can be prevented by improving the implant design or surgical techniques.

Objective By analyzing the clinical and pathological characteristics of small intestinal neoplasms of patients presenting at our hospital,this study was to improve our cognition of this disease and the prognosis.Methods We collected and reviewed the medical records of 121 patients suffering from small intestinal neoplasms,who underwent surgery at Ruijin hospital from January 2003 to June 2009.Diagnosis was confirmed by pathological examination,and patients were followed-up.Results Intestinal hemorrhage,anemia and abdominal pain were the three main symptoms for all patients.CT,and gastrointestinal endoscopy were valuable for the diagnosis of small intestine neoplasms.Compared with open surgery,laparoscopic procedures can shorten the operation time and the postoperative length of hospital stay.Conclusions Surgical procedure is the key treatment for patients with small intestinal neoplasms.Long term follow-up plays important role in the detection of other synchronous or metachronous gastrointestinal tumors and improves the prognosis.

The diagnosis and treatment of prostate cancer are being improved due to the popularized screening of prostate specific antigen. Advanced prostate cancer, in spite of its response to androgen deprivation therapy, may finally develop into castration-resistant prostate cancer (CRPC) and shorten the overall survival of the patients. Many efforts have been made by worldwide researchers for new approaches to the management of CRPC, including new hormonal therapy, cytotoxic chemotherapy, immunotherapy, and bone metastasis-targeted therapy. This paper reviews the emerging agents undergoing clinical evaluation and drugs that have received approval for the treatment of CRPC in order to provide doctors and patients with more treatment options for CRPC and improve the overall survival rate and quality of life of the patients.

Objective To determine the perioperative risks of partial hepatectomy by determining the preoperative liver functional reserve in patients with hepatocellular carcinoma (HCC),and to compare the model for end-stage liver disease (MELD) score with the Child-Pugh classification in predicting prognosis.Methods We reviewed the clinical data of 202 patients with HCC who underwent partial hepatectomy.The MELD score and the Child-Pugh classification were determined preoperatively.Results The incidence of postoperative liver dysfunction happened in 44.0％ of Child A patients,50％ in Child B patients,41.6％in patients with a MELD score below 14,and 91.7％ in patients with a MELD score of ＞ 14.The difference between the rates of postoperative liver dysfunction in patients with a preoperative MELD score above 14 and below 14 was significant (P ＜ 0.05),while that between patients with Child-Pugh A and B was insignificant (P ＞ 0.05).The incidences of postoperative liver dysfunction in patient with a MELD ＜ 8,8 ≤ MELD ≤ 14,MELD ＞ 14 were 38.2％,57.6％ and 91.7％,respectively,indicating that there was a positive co-relationship between the MELD score and the incidences of liver dysfunction.The Spearman rank correlation test showed the MELD score was significant correlated with the Child-Pugh score (r =0.404 ; P ＜ 0.05).The areas under the ROC curves of the MELD score and the Child-Pugh score were 0.703 and 0.587 (P ＜ 0.05).Conclusions The MELD score predicted postoperative liver dysfunction more accurately than the Child-Pugh classification.HCC patients undergoing partial hepatectomy with a preoperative MELD score ＞ 14 had a high perioperative risk.To ensure the safety of partial hepatectomy,HCC patients with a preoperative MELD score ＞ 14 requires active preoperative preparation,bringing the score near to or less than 14.

Objective: To set a quantified diagnostic standard for large intestinal cancer of spleen qi deficiency syndrome. Methods: The spleen qi deficiency syndrome was identified by experts on the basis of clinical epidemiological investigation of 311 patients suffering from large intestinal cancer. Corresponding points were assigned to the correlative factors (traditional Chinese medicine symptoms) on the basis of symptom differences between spleen qi deficiency syndrome and non-spleen-qi-deficiency syndrome. The best threshold was determined by receiver operating characteristic curve (ROC) according to syndrome differentiation from expert team, and the quantified diagnostic standard was established. The syndrome identification from the expert team which was regarded as golden standard was tested retrospectively. Results: All the traditional Chinese medicine symptoms possibly related to spleen qi deficiency syndrome were analyzed based on the opinions of experts, and 28 symptoms were confirmed as candidate correlative factors. The occurrence of 11 symptoms between spleen qi deficiency syndrome and non-spleen-qi-deficiency syndrome showed statistical differences by means of crosstabs analysis (P<0.05). The 11 symptoms were filtered by logistic regression analysis, and tiredness, fatigue, loose stool, and poor appetite were finally determined as the symptoms relative to large intestinal cancer. These four symptoms were analyzed with conditional probability conversion and endowed with 16, 11, 4 and 8 points respectively. The diagnostic standard of spleen qi deficiency syndrome of large intestinal cancer was over 13 points. The sensitivity, specificity and accuracy of retrospective examination were all above 80%, and its positive likelihood ratio was 9.89. Conclusion: The quantified diagnostic standard for spleen qi deficiency syndrome of large intestinal cancer is in accordance with clinical characteristics of large intestine cancer and the characteristics of TCM syndrome diagnosis.

ObjectiveTo study the effect of Rehabilitative Ankle-Foot Orthoses training program on walking function of hemiplegic patients after stroke .Methods95 patients were randomly divided into two groups: observed group (49 cases) and control group (46 cases). The patients of control group were trained by routine rehabilitation training program, the patients of observed group were trained by Rehabilitative Ankle-Foot Orthoses and routine rehabilitation training program.ResultsAfter training, either observed group or control group showed significant improvement at walking function and ADL(P<0.01), but the improvement on observed group were more marked than coutrol group(P<0.01 and P<0.05). ConclusionsThe ability of walking in acute stroke patients were obviously improved, and the degree of the disability of them was decreased by Rehabilitative Ankle-Foot Orthoses.

Objective To investigate the different effect among ropivacaine,bupivacaine,lidocaine on analgesia after harvesting grafts from the scalp in burn patients. Methods 84 patients who need harvesting grafts from the scalp after burn were divided in 4 groups random-ly(n=21). Patients in group C hypodermically injected with saline 200 mL were control,while patients in group R injected with 0. 05% ropi-vacaine 200 mL,group B with 0. 188% bupivacaine,and group L with 0. 1% lidocaine. Motor activity assessment scale( MAAS) and visual analogue scale(VAS) were made before anesthesia(T0) and 20 min,5 h,10 h after awake of patients. VAS were made focus on head and body in part. Vital signs were also monitored and recorded for assessment of security. Results All patients in 4 groups had passed the period of operation safely. Patients in group R have better VAS than other groups. Conclusion Low concentration ropivacaine hypodermically injec-tion of head is helpful to relieve the pain after harvesting grafts from the scalp.

Objective To elucidate the immunologic mechanism and clinical effect of high intensity focused ultrasound (HIFU) combined with dendritic cell and cytokine induced killer cell (DC-CIK) immunotherapy on patients with pancreatic cancer.Methods Seventy-two pancreatic cancer patients were divided randomly into 2 equal groups,one treated with HIFU only the other treated with HIFU and DC-CIK immunotherapy.Ultrasound imaging and a variety of immunological indexes were recorded before and after treatment and the clinical effects in the two groups were compared.Moreover,autogenous tumor cells were isolated from the combination therapy group and the killing activity of DC-CIK which loaded tumor antigen processed by HIFU on autogenous tumor cells was observed.Results Tumor antigen processed by HIFU can improve the killing activity of DC-CIK on autogenous tumor cells.After treatment,the immunological indexes,of all patients were better than before treatment.(58.26 ± 17.97 versus 52.15 ± 14.22 pg/ml with IL-12 22.14 ± 6.39 versus 17.36 ± 5.73 ng/ml with HSP70 and 0.94 ± O.34 versus 1.32 ± O.61 ng/ml with TGF-β,P ＜ 0.05 ) ; The combination group was significantly better than the HIFU group with regard to the average scores of quality of life (75.89 ± 19.65 versus 67.22 ± 16.34,P＜0.05),pain (3.15 ±0.82 versus 3.59 ± 1.04,P ＜0.05),tumor markers (107.55 ±27.58 versus 123.63 ±34.12 U/ml) and survival time (18.92±6.47 versus 13.36 ±5.78 mos).Conclusion HIFU can improve the immunologic status and anti-tumor response in patients with pancreatic cancer.HIFU combined with DC-CIK has good synergistic therapeutic effect for treating pancreatic cancer.

Objective To investigate the effects of Saussurea involucrata extract pretreatment on the expression of the Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) in focal cerebral ischemia/reperfusion in mice and its possible neuroprotective mechanism.Methods Seventy-two Kunming mice were randomly divided into four groups:sham operation,saline,Saussurea involucrata extract,and edaravone groups (n =18 in each group).Saussurea involucrata extract 0.8 g/kg was given intraperitoneally in the Saussurea involucrata extract group; edaravone 3 mg/kg was given in the edaravone group; and the same volume of saline was given in the saline group.A model of middle cerebral artery occlusion (MCAO) was induced after 7 days of continuous injection.Cerebral infarct volume was determined by 2,3,5-triphenyltetrazolium staining.Immunohistochemical staining was used to detect TLR4-positive cells in ischemic brain tissue.Reverse transcriptase polymerase chain reaction was used to detect the expression of TLR4/NF-κB mRNA.Results The cerebral infarct volume in mice in the saline,Saussurea involucrata extract and edaravone groups was 131.55± 28.25 mm3,84.10 ±13.92 mm3 and 65.10 ± 6.78 mm3,respectively.There were significant difference (F =10.158,P =0.012).The infarct volume in the Saussurea involucrata extract group (P =0.020) and edaravone group (P0.005) was significantly less than that in the saline group,and there was no significantly difference between the 2 groups.The numbers of cortex and TLR4 positive cells in hippocampus area at the ischemic sides in the saline group were significantly more than those in the sham operation group (all P ＜0.001).The numbers of positive cells of cortex and TLR4 in the Saussurea involucrata extract group and the edaravone group were significantly decreased compared to the saline group (all P ＜ 0.05),and there was no significant differences between the Saussurea involucrata extract group and the edaravone group.The expressions of TLR4,p50,and p65 mRNA in the saline group were significantly up-regulated compared to the sham operation group (all P =0.000).Saussurea involucrata extract could significantly down-regulate the expressions of TLR4,p50,and p65 mRNA at 24 hours after ischemia/reperfusion (all P =0.000).Edaravone could significantly down-regulate the expressions of TLR4 and p65 mRNA (all P =0.000) and it had a down-regulated trend for the expression of p50 mRNA (P =0.053); while there was no significant difference in the expressions of TLR4 and p65 mRNA between the Saussurea involucrata extract group and the edaravone group.Conclusions Saussurea involucrata extract pretreatment may significantly reduce the cerebral infarct volume,down-regulate the expressions of TLR4 and NF-κB subunit,and play a neuroprotective effect by inhibiting inflammatory response after ischemia.
