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 observe the effect of Allicin in cardial fibroblasts (CFs) proliferation and Collagen secretion,and to explore its role on TLR4/NF-κB signal pathway.Methods:CFs of neonatal Wistar rats were isolated and cultured ,then was stimulated with AngⅡ.CFs proliferation was measured by thiazolyl blue ( MTT) assay.The expression of collagenⅠ,collagenⅢ was measured by ELISA.mRNA expression of TLR4 and NF-κB were detected by reverse transcription-polymerase chain reaction ,protein expression of TLR4 and NF-κB were detected with Western blot.Results: Allicin could reduced MTT value of cardial fibroblasts ( P<0.01 ) , and inhibited expression of collagenⅠ,collagenⅢ(P<0.01),which in a dose-dependent manner.Allicin could reduced mRNA expression of TLR4 and NF-κB and protein expression of TLR 4 and NF-κB in CF induced by Ang Ⅱ ( all P<0.01 ) .Conclusion: Allicin can inhibit Myocardial fibrosis ,which mechanism is possible by inhibiting TLR 4/NF-κB signal pathway.

Objective To investigate the efficacy and side-effect of docetaxel and cisplatin induction chemotherapy followed by concurrent chemoradiotherapy in locally advanced non-small cell lung cancer (NSCLC).MethodsEighty-six patients with histologically confirmed locally advanced NSCLC were randomized into induction chemotherapy followed by concurrent chemoradiotherapy (ICCRT)arm or concurrent chemoradiotherapy (CCRT) arm. Both arms were treated with intensity-modulated radiation therapy. Induction and concurrent chemotherapy regimen consist of docetaxel and cisplatin. Results Follow-up rate of the whole group is 100％.The response rate in the CCRT arm and ICCRT arm is 70％ and 80％ ( χ2 =1.26,P =0.261 ),respectively; and 1-,2-,3-year survival rate is 65％ and 85％,40％ and 50％,33％ and 44％ (χ2 =3.90,P=0.048),respectively; the median survival time and time to progression is 17.5 and 22.0 months and 14.0 and 19.0 months respectively.Major adverse effects are leukopenia (43 and 32 cases,χ2 =3.48,P =0.062),radiation esophagutis (26 and 20 cases,χ2 =0.12,P =0.730),anemia (26 and 16 cases,χ2 =2.34,P =0.126) and radiation pneumonitis (13 and 9 cases,χ2 =0.37,P =0.541 ).ConclusionsICCRT for locally advanced NSCLC can improve the overall survival rate and time to progression,induction chemotherapy did not increase side-effects.There was no difference in response rate between CCRT and ICCRT arm.

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.

Objective To investigate the therapeutic effect and side effects of concurrent chemotherapy and intensity-modulated radiotherapy (IMRT) following induction chemotherapy (IC) in patients with locally advanced nasopharyngeal carcinoma (NPC).Methods From January 2005 to January 2009,62 cases of locally advanced NPC confirmed by pathological and cytological examination received IC with vinorelbine (25 mg/m2) plus cisplatin (25 mg/m2) for 2-4 cycles and then concurrent chemotherapy and IMRT.Conventional fractionated radiotherapy was adopted in IMRT.The radiotherapy for the nasopharyngeal region was performed a dose of 72-76 Gy/36-38 fractions,and additional 5-Gy gammaknife treatment was carried out in case of local tumor residue.Prophylactic irradiation to the cervical lymph nodes was performed at a dose of 50 Gy,and the dose was increased to 60-70 Gy in case of lymph node enlargement.Results The follow-up rate was 100％.The patients showed a response rate (RR) of 89％ in the nasopharyngeal region and an RR of 90％ in the cervical lymph nodes.The 1-,2-,and 3-year overall survival rates,disease-free survival rates,local relapse-free survival rates,and distant metastasis-free survival rates were 97％,92％,and 82％,94％,73％,and 65％,97％,89％,and 87％,and 97％,84％,and 77％,respectively.The incidence rates of grade 3-4 acute reactions were 37％ for leucopenia,18％ for thrombocytopenia,and 6％ for mucositis.No grade 3-4 long-term temporomandibular joint injury and xerostomia were observed.Conclusions Concurrent chemotherapy and IMRT following IC with vinorelbine (25 mg/m2) plus cisplatin (25 mg/m2) have tolerable adverse effects and can achieve high survival rate in the patients with locally advanced NPC.

Objective To understand clinical distribution and antimicrobial resistance characteristics of Pseudomonas aeruginosa(P.aeruginosa)isolated from hospitalized patients, so as to provide reference for the empiric use of antimicrobial agents and control of healthcare-associated infection(HAI).Methods Clinical distribution and antimicrobial susceptibility testing results of P.aeruginosaisolated from patients in a hospital between 2012 and 2016 were analyzed retrospectively, statistical analysis were conducted based on different wards, specimen types and age groups.Results A total of 2 432 strains of P.aeruginosa were isolated from2012 to 2016, most of which were isolated from intensive care unit(ICU)(n=727, 29.89％), the main specimen was sputum(n=2 064, 84.87％). Resistance rates of P.aeruginosa to other antimicrobial agents except piperacillin/tazobactam in each year from 2012 to 2016 were significantly different(all P＜0.05).Resistance to piperacillin, ceftazidime, cefepime, imipenem, meropenem, levofloxacin, and ciprofloxacin decreased after peaked in2014;resistance rates to amikacin, gentamicin, and tobramycin were all low, showing decreased trend year by year(all P＜0.05).Except resistance rates to cefepime and tobramycin, resistance rates of P.aeruginosafrom sputum specimen were all higher than other specimens(all P＜0.05).Resistance rates of P.aeruginosaisolated from patients aged≥65 years to most antimicrobial agents were significantly higher than those isolated from patients aged＜65 years(all P＜0.05).Except resistance rates to gentamicin and tobramycin, resistance rates of P.aeruginosaisolated from ICU were higher than those isolated from other departments, which were 7.71％-66.02％.Resistance rate of P.aeruginosaisolated from department of surgery were relatively low, which were 1.69％-11.86％.Conclusion Clinical distribution of antimicrobial resistance of P.aeruginosais obviously heterogeneity, empiric antimicrobial use and formulation of HAI monitoring measures should be based on the data of antimicrobial resistance in different wards, different infection sites, and different age.

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.
