Esophageal cancer is one of the most high incidence of malignant tumors in China. However, the evaluation of chemoradiotherapy curative effect for esophageal cancer is lack of accurate and uniform criteria. In recent years, the imaging evaluation methods for chemoradiotherapy response in esophageal cancer have made some progress. The methods mainly include X-ray barium examination, endoscopic ultrasonography (EUS), computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography-computed tomography (PET-CT), and so on. Imaging examination has the advantages of safety, non-invasion and repeatability, and so on, which is a progressing tool for curative effect evaluation. Current status of the application of medical imaging which is used to evaluate esophageal cancer chemoradiotherapy curative effect were reviewed in this paper.

The standardized prevalences of CDS suggestiondiagnosed metabolic syndrome(MS) and its components were 11.46% in MS,5.17% in diabetes,16.35% in hypertension,25.59% in high triglyceride level,4.72% in low HDL-C level,18.84% in overweight or obesity in 2512 randomized official employees in Fushan city of Guangdong province in 2003.The MS prevalence was increased with ageing.

Screening the 2512 employees aged 20~94 years in Fushan city by 75 g OGTT showed that 5.51 mmol/L of FPG was the optimal cut-point for diagnosis of diabetes with a sensitivity of 80% and a specificity of 80%; 5.15 mmol/L of FPG was the optimal cut-point for the diagnosis of IGT.It is reasonable to lower FPG cut-point for IFG.

Objective To study the incidence of malignant tumors in renal allografts and explore the mechanism of increased incidence.Methods A retrospective study was performed on 1 120 renal allografts under at least 0.5 year immunosuppression from 1978～2000. Results 47 cases of malignant tumors were found in 1 120 cases undergoing renal transplantation with the incidence being 4.2?%. 40 cases had intact medical history and 34 cases were demonstrated pathologically. Most patients accepted operations, additional therapies including chemical or radiological and immunological therapies. 25 cases survived and the longest survived time was 4.5 years. Conclusions The incidence of malignant tumors in renal allografts was higher than normal persons. Besides the outcome of immunosuppression, the effects of transplantation itself, such as oncogene chimera, transition of carcinogenic virus and so on, can not be neglected.

Objective This report investigate the intervention effect of the water extract of Alpinia oxyphylla Miq. fruit (AOF)on memory impairment and the mechanism in cerebral ischemia rats. Methods 48 Rats were randomly divided into sham-operated group(n=12), ischemia group(n=12), AOF group Ⅰ( n= 12)and AOF group Ⅱ (n= 12). The model of transient cerebral ischemic/reperfusion was made by bilateral occlusion of common carotid arteries in rats and combination with reducing blood pressure with an abdominal injection of so-dium nitroprusside. Learning-memory ability was observed by step through test. The content of NO and the activi-ties of NOS were measured in hippocampus. Results In step through test,the latency in ischemia group[(143.8±65.2)s]significantly decreased, the number of errors (8.9±4.2 ) significantly increased compared with sham-operated group [latency: (257.2±67.1 ) s; number of errors: (1.7±1.1 ), P<0.01 ]. The latency in AOF group Ⅰ and AOF group Ⅱ[(186.5±46.2) s, (193.4±43.7 ) s ] significantly increased, the number of errors (6.1±2.9,5.2±2.1 ) significantly decreased compared with ischemia group(P<0.05, P<0.01). In hippocampus, the content of NO and the activities of NOS in ischemia group [(56.53±27.42) nmol/mg prot, (17.23±5.64) nmol/mg prot] significantly increased compared with sham-operated group[ (40.02±17.9 ) nmol/mg prot, ( 10.46±6.15)nmol/mg prot], and in AOF group Ⅰ and AOF group Ⅱ [content of NO:group Ⅰ (46.60 ±20. 26)nmol/mg prot,group Ⅱ (42.38±21.23) nmol/mg prot ;activities of NOS:group Ⅰ (13.98±5.13 ) nmol/mg pint,group Ⅱ(13.61±5.27) nmol/mg prot] significantly decreased compared with ischemia group(P<0.05). Conclu-sion AOF could significantly ameliorate the memory impairment in cerebral ischemic rats. Its effects may be in-volved in the decrease of content of NO and activities of NOS in hippocampus.

CT findings and complete clinical data of 185 cases with closed chest injuries were retrospectively analyzed.The diagnosis of 185 cases were pulmonary contusion ( n = 185 ),pulmonary laceration ( n = 35 ),Macklin effect ( n = 5 ) and lung herniation ( n = 1 ).CT findings of lung contusion appeared as thick and vagur lung marking (n =9),small points shadows (n = 12 ),blotchy shadows (n =48),small pieces shadows (n=10),ground-glass shadows (n=16),large pieces shadows (n =5),diffuse patchy clouding shadows (n = 17) or mixed lesions (n = 68).CT appearance of lung laceration included pulmonary hematomas (n = 12),cavitary lesions with air ( n = 19),cavitary lesions with air-fluid levels ( n = 53 ).Macklin effect appeared as bronchus-,pulmonary vessel-adjacent air collection and mediastinal air collection (n=5).Traumatic pulmonary hernia appeared as lung herniation through an intercostal space.Initial CT scan missed one case of pulmonary contusion and 2 cases of pulmonary laceration.

Objective To evaluate the effect of the percutaneous nephrolithotomy ( PCNL) in the manage-ment of complicated upper ureteric calculi , compared with retroperitoneal laparoscopic ureterolithotomy ( RLU ) . Methods Seventy-one cases with complicated upper ureteric calculi were retrospectively investigated ( PCNL group 23 cases,RLU group 29 cases).Clinical data including operation time ,stone free rate and the surgical complications were statistically analyzed .Results All the operations were successful in all 52 cases.Compared with the RLU group,the PCNL group had a significant shorter operation time [(45.12 ±11.56)min vs (82.03 ±12.45)min,t=10.13,P<0.01],and significant difference were detected .A week after the operation,the PCNL group showed a stone free rate of 95.6%(22/23) while the RLU group 100.0%(29/29),and no significant difference were detec-ted.No significant complications ,such as intraoperative or postoperative bleeding and damage to surrounding organs , were detected.The patients were followed up for 6 to 12 months(mean,9 months),and no recurrent stones or ureteral stricture were developed during the period .Conclusion Both PCNL and RLU are safe and effective for complicated upper ureteral calculi.The appropriate method depends on the patients′specific conditions,the unit equipments and the experience of operator .

Objective To observe the clinical efficacy of Huxinkang Pills in treating patients with unstable angina pectoris (UAP) and its effects on the tumor necrosis factor-α (TNF-α) and N-terminal pro-brain natriuretic peptide (NT-proBNP). Methods Sixty patients with UAP were randomly divided into the treatment group and the control group, 30 cases in each group. Patients in the treatment group were treated with Huxinkang Pills based on the basic western medicine, while the patients in the control group were treated with Tongxinluo Capsules based on the basic western medicine. The treatment course was 4 weeks. Clinical efficacy and the change of the TNF-α and NT-proBNP levels before and after treatment were observed. Results The general efficacy, electrocardiograph efficacy, angina pectoris efficacy, TCM syndrome efficacy and glonoine reduction of the two groups had statistically difference (P<0.05) respectively, and the efficacy of the treatment group was superior to that of the control group (P<0.05). The TNF-α and NT-proBNP levels in both groups before and after treatment had statistically difference (P<0.05) respectively. The differences in TNF-α and NT-proBNP levels between both groups after treatment were all statistically significant (P<0.05), and these indexes of treatment group were superior to those of the control group (P<0.05). Conclusion Huxinkang Pills are remarkable in treating patients with UAP, and able to restrain the levels of TNF-α and NT-proBNP.

Objective To observe the changes of foot processes,expression and distribution of transient receptor potential cation channel 6 (TRPC6) in podocytes by puromycin aminonucleoside (PAN) and dexamethasone (DEX) intervention,then to investigate the function of TRPC6 in podocytes and its relation to proteinuria in kidney diseases.Methods Podocytes cultured in vitro were divided into three group:control group,PAN stimulation group and DEX intervention group.Mouse podocyte cell line (MPC5) were cultured in 0.02％ dimethyl sulfoxide (DMSO) in control group,subjected to PAN (50 μg/ml) treatment alone or with DEX (1 μmol/L) in other two groups for 8 h,24 h,48 h.The podocyte morphology was observed and took pictures by phase-contrast microscope,then the differences of morphology and areas were analyzed.The distribution,mRNA expression and protein expression of TRPC6 were detected by indirect immunocyto-fluorescence,real-time quantitative PCR and Western blotting,respectively.Results The well-developed podocyte arborization and interconnection was formed in control group,but PAN led to significant shrinkage of podocytes (P ＜ 0.05),together with podocyte foot process retraction,effacement and loss of cell contact.DEX significantly prevented the shrinkage and apoptosis of podocytes.The apoptosis rate was significantly increased after PAN stimulated 48 h (P ＜ 0.05).Real-time quantitative PCR and Western blotting found TRPC6 mRNA and protein expression were prone to increase in PAN group compared with control group (P ＜ 0.05).The distribution of TRPC6 becamed abnormal in PAN group.DEX decreased TRPC6 mRNA and protein expression at 48 h compared with PAN group (P ＜ 0.05).The abnormal distribution of TRPC6 was also alleviated by the protection of DEX.Conclusion DEX exerts a direct action to podocyte which retains the integrity of slit diaphragm against podocyte injury,and alleviates proteinuria via stabilizing mRNA,protein expression and distribution of TRPC6.
