Objective To investigate the changes of high mobility group box 1 (HMGB1),glutathione peroxidase(GPX3) in thyroid carcinoma and thier relationship with pathological characteristics.Methods The levels of HMGB1 and GPX3 were detected by using ELISA in 153 cases of thyroid cancer,120 cases of benign thyroid nodules and 120 healthy controls.The changes of HMGB1 and GPX3 in the patients with thyroid cancer were analyzed.Their application value in thyroid cancer was analyzed by using the receiver operating characteristic(ROC) curve.Results The plasma HMGB1 level and the HMGB1 positive expression rate in the thyroid cancer group were higher than those in the benign thyroid nodules group and control group(P＜0.05),while the plasma GPX3 level and GPX3 positive expression rate in the thyroid cancer group were lower than those in the benign thyroid nodules group and control group(P＜0.05).There were no significant differences in the levels of plasma HMGB1,GPX3 and the positive rates of HMGB1 and GPX3 between the thyroid benign nodule group and the healthy control group (P ＞ 0.05).The plasma H MGB1 expression in thyroid cancer was closely related with the infiltration degree,clinical stage and lymph node metastasis(P＜ 0.05),and the GPX3 expression was related with the tumor stage and lymph node metastasis(P＜0.05).The ROC curve showed that the sensitivity and specificity of HMGB1 and GPX3 for diagnosing thyroid cancer were 76.3％ and 85.5％,70.8％ and 82.2％ respectively.Conclusion Plasma HMGB1 and GPX3 expression levels are closely associated with the occurrence and progression of thyroid cancer.

Objective To investigate the influence of pain on liver function recovery after hepatectomy Methods Clinical data of 257 patients with primary hepatocellular carcinoma were analyzed retrospectively. The patients were divided into effective analgesia group(NRS ≤ 3 points)and ineffective analgesia group(NRS > 3 points)according to the digital hierarchy(NRS). The serum liver function indexes including ALT,AST,TBiL, ALB and PT were compared in 2 groups. Results There was no significant difference in preoperative liver function between 2 groups but the levels of ALT ,AST ,PT and TBIL at 1st ,3rd ,5th and 7th days postoperatively were lower in effective analgesia group than those in ineffective analgesic group after surgery(P<0.05). The incidence of the delay of liver function was lower in effective analgesia group than that in ineffective analgesic group. Conclusion Effective analgesic treatment can reduce liver damage and accelerate liver function recovery.

Objective To prepare rabbit anti-human RBBP10 polyclonal antibody and then character them.Methods New Zealand rabbit was immunized with RBBP10 protein,Polyclonal antiserum was analyzed by ELISA and Western blot.Results The titer of the antiserum obtained in this experiment determined by ELISA was up to 1∶16000 and the sensitivity was at least 10?g/?l.Western blot results show the antibody has high specificity.Conclusions Preparation the Rabbit anti-human RBBP10 Polyclonal antibody in this method is successfully,The expression of the RBBP10 protein in tumor can be detected in immunohistochemistry method,it is useful.

[Objective]To investigate the prophylactic effects of intra-articular injection of salvia miltiorrhiza on joint adhesion. [Methods]Twenty-four Japanese male rabbits were randomly divided into 3 groups.All right hind knees were made in this way: the auterior wall of suprapatellar bursae was scraped, the posterior wall of suprapatellar bursae and the infrapatellar fat pad were cut off. Each knee was injected with physiological saline 0.3 ml for group A, sodium hyaluronate injection 0.3 ml for group B, and salvia miltiorrhiza injection 0.3 ml for group C. All right hind knees were immobilized in the extension position with a long leg plaster cast for 4 weeks, and injected weekly.[Results]After 4 weeks, the joint movement range in group B or C was larger than that in group A (P<0.01), and there was no significant difference (P>0.05)compared to group B and group C. The scoring of joint adhesions in group B or C was smaller than that in group A (P<0.01), and there was no significant difference(P>0.05)compared to group B and group C. The scoring of histological changed of the synovial membrane in group B or C was smaller than that in group A (P<0.01), and there was no significant difference(P>0.05)compared to group B and group C.Total collagens content of the synovial membrane in group B or C was smaller than that in group A (P<0.01), while that of group C was less than in group B(P<0.01). [Conclusion]Similarly to sodium hyaluronate, salvia miltiorrhiza can effectively prevent joint adhesions.

Homoacetogens are a group of microorganisms with application potential to produce chemicals and biofuels by the bioconversion of synthesis gas. In this study, we collected waste activated sludge samples to screen homoacetogens by Hungate anaerobic technique, and studied the effect of pH on acetate and alcohol production from H2/CO2 gas. The mixed culture contained Clostridium ljungdahlii, Lysinibacillus fusiformis and Bacillus cereus. Acetate concentration achieved 31.69 mmol/L when the initial pH was 7. The mixed culture containing homoacetogen could converting H2/CO2 to acetate, which provides an efficient microbial resource for the bioconversion of synthesis gas.

Objective To observe the changes of behavior, intracellular free calcium and the expression of calmodulin dependent protein kinase Ⅱ(CaMKⅡ) in the hippocampal neurons of chronic forced swimming stress rats. Methods Male Wistar rats were randomly divided into control group and chronic forced swimming stress group. The behavior was examined using sucrose preference test, open-filed test and Morris water maze. The intracellular free calcium was examined by fluorescence spectrophotometer. The expression of CaMKⅡ was detected using colloidal gold immunoelectron microscopy technique, Western blotting and RT-PCR. Results The consumption of sucrose and erect quantity of chronic forced swimming stress group were lower than those of control group(P<0.01, P<0.05). The escape latency time in Morries water maze test of chronic forced swimming stress group was higher than that of control group(P<0.01). The intracellular free calcium level and the expression of CaMKⅡ in the hippocampus was higher than that of control group(P<0.01).Conclusion The lasting dysfunction of Ca~(2+)/CaMKⅡ signaling cascades in hippocampus may play important roles in the pathogenesis of chronic forced swimming stress rats.

Objective To evaluate the pulmonary protection of dexmedetomidine during one-lung ventilation in patients undergoing radical operation for lung cancer.Methods Thirty patients of both sexes,aged 40-70 yr,weighing 50-80 kg,of ASA physical status Ⅰ-Ⅲ,scheduled for elective radical operation for lung cancer,were randomized into 2 groups (n =15 each):dexmedetomidine group (group D) and control group (group C).Before induction of anesthesia,a loading dose of dexmedetomidine 1.0 μg/kg was infused over 10 min,followed by continuous infusion of dexmedetomidine at a rate of 0.6 μg· kg-1 · h-1 until the chest was closed in group D,while the equal volume of normal saline was given in group C.Immediately after induction of anesthesia,at 30 and 60 min of one-lung ventilation,and at the end of operation,arterial blood samples were collected for determination of the serum concentrations of TNF-α,IL-6 and IL-8,and for blood gas analysis.Oxygenation index was calculated.Results Compared with group C,the serum concentrations of TNF-α,IL-6 and IL-8 were significantly decreased,and oxygenation index was increased in group D.Conclusion Dexmedetomidine can mitigate inflammatory responses during one-lung ventilation and improve pulmonary function,thus providing pulmonary protection in patients undergoing radical operation for lung cancer.
