Objective To investigate the relationships between the expression of VEGF,its receptor KDR/flk-1,cNOS mRNA and angiogenesis,cell proliferation,metastasis in human hepatocellular carcinoma(HCC). Methods Immunohistochemical analysis using antibodies against VEGF and its kinase insert domain receptor (KDR) was carried out.cNOS mRNA expression in HCC,liver cirrhosis and normal liver tissue was observed by in situ hybridization.CD34 immunostaining was used to measure the microvascular density(MVD)and proliferative index was evaluated by Ki-67 immunostaining. Results The expressions of VEGF and KDR of HCC were significantly related to MVD,proliferation and metastasis of HCC(P

Objective To investigate the association of angiotensinogen(AGT)gene A-6G、T174M and G-217A polymorphisms with the risk of essential hypertension(EH)in the elderly of Han nationality.Methods Genotypes of AGT gene A-6G,T174M and G-217A polymorphisms in 177 aged EH patients and 86 sex and age-matched controls were analyzed with gene chip technology.Results The A-6G and T174M polymorphisms of AGT gene were significantly associated with EH.The numbers of the three genotypes of A-6G were 113,58 and 6 in the patient group and 70,15 and 1 in the control group(P= 0.014)and those of T174M were 94,77 and 6,60,25 and 1(P=0.031),respectively.G-217A polymorphism was not related to EH.Individuals carrying A-6G AA and T174M CC genotypes showed 57% and 56% lower risk of EH(OR=0.43;95%CI=0.23-0.82 and OR=0.44;95%CI=0.25-0.79, respectively).Conclusions The A-6G AA and the T174M CC genotype may be related with decreased risk of EH and G-217A polymorphism may have little role in the etiology of EH in Han nationality.

OBJECTIVETo investigate clinical outcomes of tendon allograft reconstruction with arthroscopy minimally invasive technique at stage I for the treatment of knee dislocation with multiple ligaments injury.

METHODSForty-eight patients with knee dislocation were reconstructed anterior and posterior ligament under arthroscopy at stage I from January 2008 to January 2012, and repaired ligaments injury of knee joint by minimally invasive technique. There were 38 males and 10 females aged from 20 to 59 years old with an average of 35.6 years old; 22 cases on the left side and 26 cases on the right side; the time from injury to operation ranged from 2 d to 2 weeks. Two cases combined with anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL) and posterolateral complex injuries, 36 cases combined with ACL, PCL, and MCL injuries, 10 cases combined with ACL, PCL and PLC injuries; 4 cases combined with peroneal nerve injury. Lysholm scoring were used to compared the cases before operation and final following-up to evaluate knee function.

RESULTSAll patients were followed up from 12 to 30 months with an average of (18.2 ± 6.3) months. Activity and stability of joint were obviously improved. Lysholm score were improved from 40.3 ± 4.1 before operation to 87.0 ± 6.4 at final following-up.

CONCLUSIONReconstruction with arthroscopy minimally invasive technique at stage I for the treatment of knee dislocation with multiple ligaments injury could recover stability of joint better,reserve joint function. Preoperative training and postoperative individualized rehabilitation treatment is the key point of recover knee joint function.

Objective To explore the pathological changes by CT scan on localized thermochemotherapy dur- ing and after the operation of human gliomas.Methods Retrospective analysis was given to the CT scan of 37 pa- tients receiving thermochemotherapy during and after the operation,and the relation of the tumorous cells and mi- crovessels and CT density by EM were analyzed.Changes of tumorous cells and microvessels after localized ther- mochemotherapy on C_6 gliomas in rat were analyzed.Results When the tumor was low dense on CT pattern,less cellular number with increasing the amount of fluid between the cells was demonstrated pathologically.On EM,a lower cellular electron density was observed.The amount of fluid in cytoplasm was increased,the cytoplasm was porous,swelling denaturation was chiefly seen in organelle.If the tumor had mixed density on CT,cellular number was more,the amount of fluid was less.On EM,cellular electron density increased correspondingly,the fluid in cyto- plasm decreased,organdie was aggregated.After thermochemotherapy,the tumor reduced,liquefied,and vanished by CT scan.It could be observed that the tumorous cell become smaller,concentrated and cataclased,finally formed apoprotic bodies and separated from the cell in C_6 gliomas in EM.The tumorous vessels was less,smaller and thinker. Some vessels only could see the base membrane and no endothelioid cells.Conclusion The remaining tumors is van- ished by CT scan.The mechanisms of tumors disappearance proposes to explain that thermochemotherapy can dam- age C_6 glioma cells and microvessels,decrease microvessels density and induce tumor ceils apoptosis.That inhibits tu- morous angiogenesis and proliferation.

OBJECTIVETo analyze the Chinese medicine syndrome types of patients undergoing maintenance peritoneal dialysis to provide some clinical reference for the treatment based on syndromes.

METHODSAccording to the criterion made by the Nephropathy Branch of China Association of Chinese Medicine in 2006, the syndrome type of 156 patients were differentiated, and the related laboratory parameters, including serum albumin (ALB), C-reactive protein (CRP), hemoglobin (HB), total urea clearance rate (KT/Vt), residual kidney urea clearance (KT/Vr), blood flow mediated vascular endothelial dilatation (FMD) and volume overload (OH) were measured.

RESULTSSyndrome type presented in patients was different. Along with the progress of dialysis, it changed in the root syndromes from qi-deficiency to yang-deficiency and further to both yin-yang deficiency, while in the superficial syndromes it turned from turbid-damp to blood-stasis. ALB in patients with Pi-shen yang-deficiency type and both yin-yang deficiency type was significantly lower than that in patients with Pi-Shen qi-deficiency type and both qi-yin deficiency type (P < 0.05); KT/Vt in both yin-yang deficiency type was the lowest, significantly lower than that in Gan-Shen yin-deficiency type and both qi-yin deficiency (P < 0.05); OH in Pi-Shen yang-deficiency type and both yin-yang deficiency type was significantly higher than that in other types (P < 0.01). Comparison of patients' age showed that group of patients without superficial syndrome was the youngest and the group of patients with damp-heat syndrome type was the oldest (P < 0.01). CRP in damp-heat type was significantly higher than that in other types (P < 0.05); FMD was lower in blood-stasis type than in turbid-damp type and toxic heat type (P < 0.01); and OH was significantly higher in turbid-damp type than in other types (P < 0.01).

CONCLUSIONSome rules of syndrome type distribution could be seen in patients undergoing peritoneal dialysis, which is related with some laboratory parameters to a certain extent, so may provide a few references for clinical treatment based on syndrome type.

Objective To discuss the clinical characteristics and treatment of upper cervical spine injuries in the elderly. Methods A retrospective study was done on clinical data of 28 elderly patients ( > 60 years old) with upper cervical spine injuries treated from January 2003 to December 2007. There were 20 males and 8 females, at age range of 60-86 years (mean 68.1 years). Injury causes included slip in 16 patients, traffic injury in eight and fall from height in four. Atlas fractures occurred in five patients and axis ones in 15,of which there were eight patients with odontoid fractures, six with C2 vertebral arch fractures and one with C2 body fractures. Upper cervical spine injury was combined with lower cervical spine injuries in five patients. There were combined atlantoaxial injuries including odontoid fractures combined with lateral atlas fracture in one and edontoid fractures combined with anterior atlas arch fracture in one. Atlantoaxial dislocation occurred in one patient and combined spinal injury in four. Of all, eight patients were treated conservatively, eight with open surgical operation and 12 with minimally invasive surgery. Results The average hospital stay was 16.5 days, with no statistical difference be-tween conservative treatment group and open surgical operation group ( P > 0.05 ). While the average hos-pital stay in minimally invasive surgery group was shorter than that in conservative treatment and open sur-gical operation groups ( P < 0.05 ). Of all, two patients in conservative treatment group and one in open surgical operation group died and the other 25 patients were followed up for average 16.8 months (9-56 months). The satisfaction rate was 50% in conservative treatment group, 72% in open surgical operation group and 75% in minimally invasive surgery group. Complications occurred in four patients in conserva-tive treatment group, three in open surgical operation group and two in minimally invasive surgery group. Conclusions With odontoid fracture the most common injury type, upper cervical spine injuries arema-inly caused by low-energy force and characterized by low mobidity of spinal cord injuries and high possi-bility of missed diagnosis in the elderly patients. The surgical treatment especially minimally invasive surgery can bring good results compared with conservative methods.
