AIM: To evaluate the clinical efficacy of combination of active immunotherapy and allylestrenol in treatment of patients with unexplained recurrent spontaneous abortion (URSA) and to investigate a best therapeutic method in treatment of patients with URSA. METHODS: 435 patients with primary URSA were randomly assigned to three groups: 185 in combination medication group which was treated with active immunotherapy and allylestrenol, 152 in active immunotherapy group which was only treated with active immunotherapy, 98 in allylestrenol group which was only treated with allylestrenol. 96 secondary URSA in secondary URSA group were treated with active immunotherapy and allylestrenol. RESULTS: The successful pregnant rates of combination medication group, active immunotherapy group, allylestrenol group and secondary group were 92.05 %, 71.43 %, 31.51 % and 86.76 %, respectively. The successful pregnant rate in combination group were higher than that in the active immunotherapy group and the allylestrenol group (P 0.05 ). CONCLUSION: Combination of active immunotherapy and allylestrenol is better than other therapy method in treatment of patients with URSA, which is worth further widespread application in clinical practice.

Objective To investigate the correlation among expression of serum VEGF without operation between pre-and post-chemoradiotherapy in non-small cell lung cancer (NSCLC) patients, to explore the correlation of markers on prognosis and effect. Methods The serum vascular endothelial growth factor (VEGF) were detected in 50 patients without operation between pre-and post-chemoradiotherapy with NSCLC by ELISA method. The group t-test was played into before concurrent chemoradiotherapy and normal control. The paired t-test was played into before and after concurrent chemoradiotherapy. Results The prechemoradiotherapy serum VEGF ( 241.09 ± 52.45 ) ng/L in NSCLC patients was significantly higher than those in normal control patients (103.72 ± 39. 22) ng/L (t = 2. 50,P <0. 05 ). The pre-chemoradiotherapy serum VEGF in NSCLC patients was closely related to pTNM stage, distant metastasis, grade of cell differentiation and the size of the primary tumors ( t = 9. 61 - 14. 94, all P < 0. 05 ), but not to the histological classification, type of the tumor, lymph node status, age, gender of the patients or smoking or not (t =0. 58 - 1.84, all P > 0. 05 ). The pre-chemoradiotherapy serum VEGF ( 24 1.09 ± 52. 45 ) ng/L was significantly higher than that of the post-chemoradiotherapy ( 133.64 ± 33.62) ng/L ( t = 12. 20, P < 0. 01 ). The post-chemoradiotherapy serum VEGF decreases to the pre-was the biggest in the CR patients (( 92.35 ± 37.48ng/L) ,t =3.79,P <0. 01 ) ,the smallest in the PA patients ( (276.32 ±47.98) ng/L,t = 1.32,P >0. 05) ) ,and bigger in the PR patients and the NC patientspatients ( ( 113.10 ± 39. 20) ng/L,t = 13.58,P <0. 01 and ( 198.10 ± 42.68 ) ng/L, t = 4. 78, P < 0. 05 ) ), respectively. Conclusions Elevation of serum VEGF exists in patients with NSCLC . The serum VEGF in patients with NSCLC might be helpful to evaluate the biological behavior of lung cancer. Detection of VEGF expression maybe helpful for predicting the prognosis of NSCLC patients.

OBJECTIVETo observe the effect of Gingerol on endotoxemia mouse induced by heatstroke.
METHODSForty mice were randomly divided into five groups, the endotoxemia model group (A), the normal temperature group (B), the Gingerol treated group (C), the solvent control group (D), and the saline control group (E), 8 mice in each group. Group B to E was administered with saline, Gingerol, solvent and saline respectively. Mice in group B were placed at room temperature 25 +/- 0.5 degrees C , relative humidity 43 +/- 5 % for 2 hrs, while mice in the other groups were exposed under 35 +/- 0.5 degrees C and relative humidity 65 +/- 5 % for 2 hrs in an artificial hot-climate mimic cabin to establish heatstroke endotoxemia model. The energy metabolic level of celiomacrophage was detected with MTT; the phagocytic ability was examined with neutral red chromometry; the hepatocyte ultrastructure was observed with transmission electron microscopy, as well as the activity of superoxide dismutase (SOD) and the level of malondialdehyde (MDA) in plasma was tested.
RESULTSAs compared with Group A, D and E, in Group C, energy metabolic levels of macrophage, phagocytic ability, and activity of SOD were significantly higher (P < 0.01), and the level of MDA was significantly lower respectively (P < 0.01), with the levels of SOD and MDA approaching to those in Group B (P >0.05). The pathologic changes of hepatocyte ultrastructure in group C were less than those in the other three endotoxemia groups.
CONCLUSIONGingerol could raise the energy metabolic level of celio-macrophage to enhance its phagocytic ability, increase the activity of SOD and reduce the production of MDA in mouse with heatstroke endotoxemia, so as to alleviate the liver damage.

Objective To explore the effects of endoplasmic reticulum stress response(ERS) and its related apoptosis on dopaminergic neurons death.Methods NGF treated-PC12 cells were treated with 6-OHDA,MPP+ and rotenone.MTT assay and flow cytometry were used to measure the cell viability and the rate of cells apoptosis induced by those neurotoxins at different concentrations and times.The expressions of ERS-related gene XBP1,Grp78,CHOP,caspase-12 in drug-treated group and reserpine preincubation group were determined by RT-polymerase chain reaction(RT-PCR) and immunohistochemistry.Results After exposing to different concentration toxins,the vitality of PC12 cells was decreased by 52% at 100?mol/L 6-OHDA,by 44% at 75?mol/L MPP~+,and by 40% at 20 nmol/L rotenone for 24 hours respectively and ws decreased in a dose dependent manner. FCM assay confirmed time-dependent cell apoptosis.The apoptotic cells ratio of 24 h groups were (31.22?3.21)%,(27.46?2.35)%,(29.26?2.53)%,respectively(P<0.01).In 6-OHDA groups,the gene expressions of XBP1,Grp78 were approximately 2-fold increased after 8 h exposure, CHOP reached peak level at 16 h(149.5?3.3% vs 35.9?1.8%,P<0.01).The transcription level of caspase-12 was significantly higher than normal control at 16h[(95.4?2.8% vs(23.8?3.0)%, P<0.01],but was alleviated by reserpine prcincubation(62.15?4.3%,P<0.05).The increased expressions of Grp78 and CHOP after drug exposure were confirmed by immunochemistry stain.The similar results were observed in MPP~+ and rotenone groups.Conclusions The excessive ERS and ERS-activated cell apoptosis pathway may be involved in selective death of dopaminergic neurons.
