The thioredoxin system consists of thioredoxin(Trx),thioredoxin reductase(TrxR)and reduced nicotinamide adenine dinucleo-tide phosphate.Trx is a small redox-active multifunctional protein.Thioredoxin 2,which is localized in the matrix mitochondria,has been shown involved in not only oxidative stress,nucleic acid metabolism,cell grow and apoptosis,but also many diseases such as organism growth and development,oxidative stress damage,cancer and ischemical reperfusion injury.It participates in redox reactions by reversible oxidation of its active center dithiol to disulfide and catalyzes dithio-disulfide exchange reactions involving many thiol-dependent processes.As signaling molecule,Trx2 participates in many signaling pathways.

Objective To investigate the relative risk factors of glucose metabolism disorder in newborn infants.Methods Clinical information of 791 newborns suffered from glucose metabolism disorders who had been hospitalized in NICU from Jan.2004 to May 2007 were analyzed retrospectively.Four hundred and thirty-nine cases presented with hypoglycemia,275 cases presented with hyperglycemia,and 77 cases presented with both hypoglycemia and hyperglycemia.Data of risk factors were processed with both ?2 test and multiple Logistic regression analysis.Results The statistic analysis showed that low birth weight[258 cases(58.77%)],asphyxia[217 cases(49.43%)],acidosis[146 cases(33.26%)],hypothermia[128 cases(29.16%)],maternal gestational hypertension[83 cases(18.91%)],pneumonia[63 cases(14.35%)],anomaly of placenta[35 cases(7.97%)],maternal diabetes[17 cases(3.87%)] and septicaemia[10 cases(2.28%)]were significant hypoglycemia risk factors(according to the level of morbidity).Pneumonia[98 cases(35.64%)],asphyxia[129 cases(27.23%)],hypoxemia[61 cases(22.18%)]and septicaemia[24 cases(8.73%)]were significant hyperglycemia risk factors.Acidosis[33 cases(42.86%)],pneumonia[27 cases(35.06%)]and maternal diabetes[6 cases(7.79%)] were significant risk factors for neonates with both hypoglycemia and hyperglycemia.Conclusion Dynamic monitoring of blood glucose concentration and reasonable adjustment is recommended for neonates with risk factors to lower morbility and mortality.

Objective To observe the expression of mitochondrial encoding cytochrome oxidase subunitⅠ(COXⅠ) and subunitⅡ(COXⅡ) in type Ⅱalveolar epithelial cell(AEC Ⅱ) of rats exposed to hyperoxia and explore the role of COXⅠand COXⅡ in hyperoxia-induced lung injury.Methods AECⅡ were gained by primary culture from 19-days fetal rats lung.After purified,AECⅡ were randomly assigned to hyperoxia group and air group.Hyperoxia group was flushed the flake with 950 mL/L O2 and 50 mL/L CO2 at 3 L/min for 10 min,then sealed.Both groups were in CO2 culture chamber(37 ℃,50 mL/L CO2).After 6,12 and 24 hours of exposure,AECⅡ were harvested and extracted for total RNA.COXⅠand COXⅡ mRNA were detected by reverse transcription polymerase chain reaction(RT-PCR).The results were analyzed by SPSS 12.0 softwore.Results Compared with air group,COXⅠmRNA expression in hyperoxia group increased significantly at 6 hours(t=3.832 P=0.019) and 12 hours(t=10.431 P=0),respectively,then decreased to the equivalent level in 24 hours(t=0.360 P=0.731).Compared with air group,COXⅡmRNA expression in hyperoxia group increased significantly at 6 hours(t=2.795 P=0.035),then decreased to the equivalent level at 12 hours(t=0.892 P=0.40) and 24 hours(t=2.018 P=0.071).Conclusions Exposure of hyperoxia up-regulate the expressions of COXⅠmRNA and COXⅡmRNA in AECⅡ,which may be a protective mechanism of hyperoxia-induced lung injury.

OBJECTIVETo evaluate the efficacy and safety of high doses of thymopentin (10 mg/d) combined with transartery chemoembolization for primary liver cancer.

METHODSFifty primary liver cancer patients were randomly divided into two groups: therapeutic and control group, and all were treated with transfemoral artery chemoembolization (TACE) with oxaliplatin 150 mg, pharmorubicin 50 mg, 5-Fu 750 mg, CF 300 mg and lipiodol 20 ml. Therapeutic group (25) were added 10 mg thymopentin daily after TACE: i.v. on dl - d5, and im on D6 - D21.

RESULTSThere was a significant difference in adverse effect and toxicity such as naupathia,fever, swirl, asthenia observed between two groups (P < 0.05). No difference in either pre- or post-chemotherapy peripheral blood examination and biochemical assay was found between two groups (P > 0.05). In control group, CD4+ cell was 37.92% +/- 8.71% in pre-treatment, which decreased to 29.16% +/- 8.21% in post-treatment with a significant difference (P < 0.01), whereas there was no evident difference in CD4+ cell between pre-treatment and post-treatment in the treatment group.

CONCLUSIONTransartery chemoembolization combined with high dose of thymopentin in the treatment for primary liver cancer is effective and safe, and can significantly improve the immune function and the chemotherapy tolerance.

OBJECTIVETo investigate clinical effect and safety of bone-setting manipulation in treating isolated systolic hypertension combined with cervical spondylosis.

METHODSFrom January 2012 to January 2015, 320 patients suffered from isolated systolic hypertension combined with cervical spondylosis were randomly divided into treatment group and control group. In treatment group, there were 160 patients including 84 males and 76 females with an average age of (39.82 ± 10.33) years old, average blood pressure was (149.61 ± 10.75)/(81.01± 8.25) mmHg, NPQ score was 24.61 ± 8.14; treated with flexion top spin and lock bone-setting manipulation of cervical spine, once every two days for 20 days. While in control group, there were 160 patients including 90 males and 70 females with an average age of(41.37 ± 9.42) years old, average blood pressure was (151.48 ± 11.32)/ (79.65 ± 9.32) mmHg, NPQ score was 25.78 ± 9.53; treated with manipulation of reposition cervical spine by rotation, once every two days for 20 days. Blood pressure and NPQ score were tested and compared for evaluating clinical effects.

RESULTSBefore and after a period treatment, systolic pressure in treatment group was (149.61 ± 10.75) mmHg and (129.67 ± 12.26) mmHg; (151.48 ± 11.32) mmHg and (132.02 ± 11.73) mmHg in control group. After treatment, systolic pressure in both two groups was obviously decreased, and treatment group was better than control group. Before and after a period treatment, diastolic pressure in treatment group was (80.01 ± 8.25) mmHg and (78.15 ± 10.34) mmHg, (79.65 ± 9.32) mmHg and (76.89 ± 9.79) mmHg in control group, and there was no significant difference between two groups. NPQ score in treatment group was 24.61 ± 8.14 before treatment, 12.46 ± 7.94 after treatment, while in control group was 25.78 ± 9.53, 14.17 ± 8.86; NPQ score of the two groups after treatment was better than before treatment, while there was no obviously significance between two groups after treatment. The whole clinical effect in treatment group was better than control group.

CONCLUSIONBone-setting manipulation for isolated systolic hypertension combined with cervical spondylosis at early stage could receive good clinical result, and flexion top spin and lock bone-setting manipulation of cervical spine was better and safety than manipulation of reposition cervical spine by rotation.
