Objective To investigate the expressions of TESTIN gene and Caspase-3 protein and thier relations with the clinicopathological features and prognosis of esophageal squamous cell carcinomas(ESCC). Methods The expressions of TESTIN and Caspase-3 in 50 ESCC tissues and paracancerous tissues (＞5 cm apart form the ESCC tissue) were detected by immunohistochemistry.The expression of TESTIN in 65 matched-pairs of ESCC tissues was detected by Western blotting and RT-PCR. The association of TESTIN and Caspase-3 with clinicopathological features and prognosis of ESCC were analyzed. Results The immunohistochemistry examination showed that the positive rates of TESTIN protein [30. 0% (15/50)] and Caspase-3 protein [24.0% ( 12/50)] were significantly lower in ESCC tissues than those in paracancerous tissues [(84. 0% (42/50) and 94. 0% (47/50),respectively, P＜0.01)]. The mRNA level of TESTIN was down-regulated in ESCC tissues (P＜0.05). Whereas the protein level of TESTIN was down-regulated in 45 (69.2%) of 65 ESCC tissues in comparison with paracancerous tissues. TESTIN expression was positively correlated with the differentiation of ESCC, but not associated with gender, age, tumor size, TNM stage and lymph node metastasis. There was a positive correlation between TESTIN and Caspase-3 in protein expressions (P＜0. 05). Patients with negative expression of TESTIN had lower survival rate compared to those with positive expression (P＜0. 05). Conclusions The positive relation between low-expression of TESTIN and Caspase-3 implicates that both are involved in the development of esophageal squamous cell carcinogenesis, and TESTIN might be a novel ESCC marker with prognostic significance.

Objective:To investigate the effect of genistein,a soybean-derived isoflavone,on thestimulating effect on bone resorption of IL-1?.Methods:The osteoclasts(OCs)were isolated with themethods of Yu Shifeng.The rat calvaria were cultured as an organ.The cells in the experiment weregrown in four respectively:Control(without genistein or IL-1?),10~(-6) mol/L genistein,10 ?g/L IL-1?and 10~(-6) mol/L genistein+10 ?g/L IL-1?.The area of bone resorption,the concentration of Ca~(2+) in thesupernatant liquid of OCs cultures and mice calvaria were tested.The contents of acid phosphatase(ACP)were also examined by biochemistry method.The index of bone resorption was counted as the ra-tio of the experiment average and control ones,which indicated the increase in bone resorption when itwas above 1.0.Results:The area of bone resorption of 10~(-6) mol/L genistein+10 ?g/L IL-1? increasedcompared with that of 10~(-6) mol/L genistein,while the concentration of Ca~(2+) in the supernatant liquid ofOCs cultures decreased significantly.The index of bone resorption of 10~(-6) mol/L genistein+10 ?g/L IL-1? lied between 10~(-6) mol/L genistein and 10 ?g/L IL-1?.In the organ culture,there was no differencein the content of ACP among all the groups,The index of bone resorption of 10~(-6) mol/L genistein+10?g/L IL-1? was below that of 10?g/L IL-1?,but both were above 1.0.The index of bone resorptionwas below 1.0 in the group of 10~(-6) mol/L genistein.Conclusion:Genistein can suppress obviously thebone resorption simulated by single IL-1?.

Objective To detect the type of gene mutation of thalassemia in Kunming city.Methods Sixty-three cases highly suspec-tive of thalassemia were determined with the methods of ploymerase chain reaction(PCR) and reverse dot blot(RDB) for the type of gene mutation.Results According to gene analysis,35 cases were final diagnosed from 63 cases suspective of thalassemia.Among the total,4 cases were gene deficiency ?-thalassemia,and 30 cases were gene deficiency ?-thalassemia,and there was 1 case both ?-thalassemia and ?-thalassemia.There were 9 types of gene mutation with 15 gene combinations in 35 samples.The main type of ?-thalassemia was--SEA/??,there were 6 types with 11 gene combinations from the types of genes of ?-thalassemia,the highest incidence of gene mutation was 17 site,including 17 site homozygote,heterozygote and double heterozygote.Conclusions The thalassemia invasion of Yunnan has its characters,and it is valuable to launch further research.In the same patient,there are ?-thalassemia and ?-thalassemia,it signifies that those 2 types should be diagnosed in the same time,to prevent missed diagnosis.

Objective To investigate the effects of maternal long-term exposure to low-dose trichlorfon on the serum paraoxonase (PON) activity of pregnant mice and development of embryos. Methods Female ICR mice (n=120) were randomly divided into control group and trichlorfon groups of different doses,and were managed by intragastric injection with trichlorfon of 0,2,10 and 50mg/kg,respectively. All the mice were managed once a day for a consecutive of 27 days,and were subjected to mating. The pregnant mice were continued to be managed with trichlorfon for 3 days,and were sacrificed on day 3 of gestation. The serum PON and acetylcholinesterase (AchE) activities were detected,and the development of embryos was evaluated. Results The serum PON activity of 2,10 and 50mg/kg trichlorfon group were (14.15?1.22),(12.78?1.80) and (10.45?1.95)IU/mL,respectively,and that of 50mg/kg trichlorfon group was significantly lower than that of control group [(13.37?2.31)IU/mL] (P0.05),while the the percentage of abnormal embryos of 50mg/kg trichlorfon group had an increased tendency. Conclusion Long-term exposure to low-dose trichlorfon can inhibit serum PON and AchE activity in pregnant mice without obvious effect on the development of embryos.

Objective To study the cell death in macrophages (THP-1) stimulated with different agonists (H37Rv-PPD or BCG-PPD) and to investigate the relationship between Toll like receptor (TLR)-2 and THP-1 apoptosis. Methods H37Rv-PPD and BCG-PPD were used to stimulate THP-1 cells for 3 h, 8 h, 15 h and 24 h, respectively with or without TLR-2 blockade. Cells were analyzed by flow cytometry to detect the TLR-2 expression. Annexin V staining and Hochest staining were performed to evaluate apoptosis. Results The apoptosis cells were increased when stimulated with BCG-PPD and the percentage was 30.2% at 24 h, which were confirmed by Hochest staining.However, the expression of TLR-2 did not increase simultaneously with percentage of 8.8% at 24 h.Nevertheless, most cells presented with necrosis form when stimulated with H37Rv-PPD and the expression of TLR-2 remained at high level with the percentage of 17.2% at 24 h, while the percent of apoptosis rate was only 7.7%. Under treatment of TLR-2 antibodies, the percentage of apoptosis decreased to 10.5% at 24 h of BCG-PPD stimulation and TLR-2 expressions were down-regulated to less than 3% at all time points; but after H37Rv-PPD stimulation, the percentage of apoptosis and TLR-2 expression did not changed obviously. Conclusions The attenuated BCG-PPD induces THP-1 apoptosis predominately, which is partially correlated with TLR-2 expression. While virulent H37Rv-PPD induces THP-1 necrosis predominately.

Objective To explore the mechanisms by which hydrogen sulfide (H2S) regulates collagen metabolism during hypoxic pulmonary vascular structural remodeling. Methods Wistar rats were randomly divided into control group (n=6), hypoxia group (n = 6) and hypoxia+NaHS group(n= 6) H2S content in plasma was measured with spectrophotometry. The expression of collagen I was detected by immunohistochemistry. The expression of tissue inhibitor of metalloproteinase-1(TIMP-1) mRNA was detected with situ hybridization Results Compared with hypoxia group, H2S content in plasma increased significantly and the expressions of collagen I and TIMP-1 mRNA in pulmonary arteries were down- regulated in hypoxia + NaHS group. The H2S content in plasma negatively correlated with TIMP-I mRNA expression. Conclusions H2S increases the degradation of collagen in small and media pulmonary arteries of rats under hypoxia by decreasing the synthesis of TIMP-1, and therefore, attenuats the collagen remodeling in pulmonary arteries of hypoxic rats.

Objective To evaluate the feasibility and the effect of the early postoperative enteral nutrition on improving the nutritional status, cost of nutrition and hospital stay after operation in abdominal surgery.Methods 48 patients who underwent abdominal operation were allocated into 2 groups: enteral nutrition group(EN group,23 cases) and parenteral nutrition group(PN group,25 cases). It was isonitrogenous and isocaloric intake in both groups. Each day nitrogen intake (0.18±0.02)g/kg,104.6—125.52 kJ(25—30kCal/kg). EN was given at postoperation 8 hours by naso intestinal tube which was placed 30 cm distal to ligament of Treitz or jejunal export loop. PN was provided by peripherally inserted central venous catheters(PICC). The nutritional indices were investigated. A visual analogy scale was used to estimate the infection related complication, cost of nutrition and hospital stay. These parameters were evaluated preoperatively and on the 8th day after operation.Results Early postoperative enteral nutrition showed significant nutrition effect in the patients undergoing abdominal surgery. In the EN group,the nitrogen balance became positive at the postoperative day 4,whereas the nitrogen balance still remained negative in the PN group. The EN group decreased their hospital stay and cost of nutrition compared with that of the PN group(P<0.05). Conclusion The early postoperative enteral nutrition is safe and feasible. It cannot only improve the nutritional status and intestinal function obviously, but also decreased the hospital stay and cost of nutrition compared with parenteral nutrition.
