All patients were treated withYiqi Huoxue Jiedu Recipe lasting for 4 weeks (200 mL, twice a day). The main endpoint was the quantities of CD4+CD25+ cells, CD8+CD28- regulatory T cells and CD8+CD28+ cytotoxic T cells measured by flow cytometry, and the accessory endpoints were variations of symptoms which included pain, fatigue, and numbness etc.Results The quantities of CD4+CD25+ and CD8+CD28- cells significantly decreased compared with those of pre-treatment (P<0.05); the quantity of CD8+CD28+ cell increased significantly (P<0.05). Except for pain, significant improvement showed in fatigue, tinnitus, numbness, poor appetite, abdominal discomfort, insomnia, diarrhea and abnormal urinate (P<0.05).ConclusionYiqi Huoxue JieduRecipe is proved to be effective in regulating immunosuppression advanced ovarian cancer and improving patients’ life quality.

Objective:To determine the correlation of BCG concentration in Freund complete adjuvant ( FCA) and severity of arthritis during arthritis establishment in DBA 1/j male mice induced by bovine type Ⅱcollagen.Methods:CIA was induced by the im-munization of DBA1/j mice with bovine type Ⅱcollagen and BCG of various concentrations dissolved in FCA.To ascertain the effects administering the collagen booster,CIA-related features(including body weight,clinical scoring of arthritis),TNF-αin serum and the histopathological changes in the spleen and the joints regions were measured.Results:4 mg/ml BCG induced more serious arthritis than 1 mg/ml in DBA1/j mice after collagen exposure.Conclusion:There is a positive correlation of arthritis severity with BCG.Which indicates that selection of adjuvant with suitable BCG concentration could determine pathological outcome in CIA mouse model .

Objective To explore the relationship between tumor necrosis factor-?(TNF-?)level in the serum of maternal women with intrauterine infection of Toxoplasma gondii and absortion.Methods An examination was carried out on TNF-? in maternal sera and DNA of Toxoplasma gondii in the cervical secretions,and the aborted tissues of the abortion group,and the cervical secretions of the control group by ELISA and PCR,respectively.Results The TNF-? levels increased in the sera of women with intrauterine infection of Toxoplasma before abortion as compared with those of the control group and those of themselves after abortions.There were high TNF-? levels in the sera of prognostication abortion women with Toxoplasma infection before the anti-Toxoplasma treatment as compared with those of the control group and those of themselves after the treatment with azithromycin.Conclusion The results suggest that Toxoplasma gondii infection is an important factor to increase the TNF-? level in maternal serum.

Objective To investigate the expressions of inflammatory factors in papillary thyroid carcinoma tissue and their relationships with the clinical pathological characteristics,and to provide an experimental basis for guiding clinical treatment and prognosis.Methods 74 patients with papillary thyroid carcinoma dignosed by puncture were selected as experimental group,and 26 cases of healthy people were used as normal control group.The fasting venous blood samples from the subjects in two groups were collected,and the postoperative specimens from cancer tissue,adjacent normal tissue and the fasting venous blood 7 d after operation of the patients in experimental group were collected again.The interleukin 1α(IL-1α),interleukin 1β(IL-1β)and cyclooxygenase-2 (COX-2)protein expression levels in serum,cancer adjacent normal tissue and cancer tissue were detected by ELISA;the gene and protein expression levels of IL-1α,IL-1βand COX-2 were examined by real-time fluorescent quantitative method and immunohistochemistry;the relationships between their expressions and clinical stages, pathological types,lymph node metastasis of thyroid papillary carcinoma were analyzed.Results The expression levels of serum IL-1α,IL-1βand COX-2 protein of the patients in experimental group were significantly higher than those in normal control group (P<0.01);the gene and protein expression levels of IL-1α,IL-1βand COX-2 in thyroid papillary carcinoma tissue were significantly higher than those in adjacent tissue (P<0.01).There were positive correlations between the expressions of IL-1αand IL-1β,IL-1αand COX-2,IL-1βand COX-2 in thyroid papillary carcinoma tissue (r=0.64,P=0.035;r=0.71,P=0.042;r=0.69,P=0.038).Conclusion The expression levels of IL-1α, IL-1βand COX-2 in thyroid papillary carcinoma tissue are increased, suggesting that inflammation is involved in metastasis and invasion of thyroid papillary carcinoma,its application is expected to become a new means of cancer treatment strategies.

Objective To investigate differences in Rab protein expressions in McCoy cells with acute versus persistent Chlamydia trachomatis (Ct) infection.Methods Cultured McCoy cells were infected with different amounts (400,500,550 μl/well) of Ct strain D suspensions,then cultured with the medium containing 100 U/ml penicillin G (persistent Ct infection groups) or that without penicillin G (acute Ct infection groups).Ct-uninfected McCoy cells receiving no penicillin G treatment served as the blank control group,and those receiving penicillin G treatment as the penicillin group.Mter 48-hour culture,McCoy cells were lysed,proteins were collected,and total RNA was extracted from the cells.Enzyme-linked immunosorbent assay (ELISA) was conducted to measure protein levels of Rab4A,Rab6A,Rab10,Rab11A and Rab14,and fluorescence-based quantitative PCR to quantify mRNA expressions of Rab4A and Rab14 (expressed as 2-ΔΔα).Results Protein levels of Rab4A,Rab6A,Rab10,Rab11A and Rab14 were all significantly lower in the acute than in the persistent Ct infection groups (all Z =3.621,P ＜ 0.001),and lower in the persistent and acute Ct infection groups than in the blank control group (all P ＜ 0.008 3),but insignificantly different between the blank control group and penicillin group (all P ＞ 0.05).In addition,the expressions of Rab4A and Rab14 mRNAs were consistent with those of their proteins in these groups.Conclusion The transcriptional and expression levels of Rab proteins are higher in McCoy cells persistently infected with Ct than in those acutely infected with Ct.

Objective To establish a method for the determination of serum potassium using isotope dilution inductively coupled plasma mass spectrometry.Methods Frozen human serum pools of different potassium concentrations were prepared from healthy donors of Chao-yang Hospital laboratory in 2010 Serum samples were diluted with 1％ HNO3 supplemented with 41K spike and isotope ratio was measured after selection and optimization of ICP-MS analysis conditions.Serum 39K concentrations were calculated by interpolation method.3 different serum samples were used to evaluate the precision of the method.Standard Reference Material 909b Ⅰ and Ⅱ of National Institute of Standards and Technology were used to evaluate the accuracy.The recovery was evaluated through 2 serum samples added standard material for potassium,uncertainty was calculated.Results The analytical precision of serum potassium measurement was 0.14％ to 0.11％.The results of SRM909b Ⅰ and Ⅱ gave the coefficients of variation (CVs) of 0.39％ to 0.32％.Data was consistent with the certified value and the CV was + 0.12％ and + 0.49％ respectively.The recovery was 99.68％ to 100.12％ for 2 different serum samples.Conclusions ID-ICP-MS method was successfully established to measure the serum potassium concerntration precisely and accurately,it is an ideal method for the accurate determination of inorganic elements.

Objective To investigate the postmortem redistrib ution of morphine in rat model of chronic morphine poisoning. Methods Samples including cardiac blood, liver, heart, kidney, lung and brain tissues were collected in the rats with chronic morphine poisoning at 0～96 h after death, respectively. The morphine amount was measured with solid phase ext raction-gas chromatography. Results The study showed an increase in morphine concentrat ion of postmortem cardiac blood. Significant increase in morphine level was also observed 24～96 h after death in liver, heart and brain tissues, while the kid ney morphine levels decreased at 96 h after death. In the liver there was the g reatest increase (25-fold) in morphine levels 96 h after death. All the sample s showed marked alterations in morphine concentration within 96 h after death c ompared with cardiac blood at time of death. The postmortem morphine levels in b rain were closely related to those in the heart blood. Conclusion The postmortem redistribution of morphine exists in rats with chronic morphine poisoning. The brain tissues may better represent morphine levels in heart blood at the time of death.
