Abscopal effect is for tumor therapy and control of tumor metastasis.it will produce consider-able eignifieance in clinical tumor therapy.The exactly mechanisms of this effect have not been recognized com-pletely so far,and researchers find this effect is associatod with immune system response,espeeiaHy the cell-me-diated immunity.The response of abscopal effect can activate antitumor immunologic response in vivo possibly through antigen releasing and presentation,activation of T cell and natural killer cell,the role of cytokine,in-flammatory reaction,apoptosis,and etc.

Objective:To construct recombinant bacille calmette-guerin (BCG) carrying murine interleukin-12 (mIL-12) genes,and to identify the ability of recombinant BCG for submitting plasmids to eukaryotic cells. Methods:Co-expression shuttle plasmid of pBM12, including mIL-12 gene and mycobacterial replicon of Orim,was built using molecular biological approach.The pBM12 was transfected to BCG competence by electroporation to construct recombinant BCG. The plasmid of recombinant BCG was extracted for PCR identification. The ability of submitting plasmids to eukaryotic cells was determined by RT-PCR. Results:The plasmid pBM12 may be transduced into BCG with electroporation. The specific bands for mIL-12 of the recombinant BCG were detected by PCR. The specific bands for 1632 bp mIL-12 were amplified from transfected macrophages after 96 hours byRT-PCR. Conclusion:The recombinant BCG carrying pBM12 was constructed successfully. The recombinant BCG can submit the carried genes to mice macrophages.

Bone metabolism of OVX rats was examined by single photon radionulide emission computed tomograpy.Results: Compound Zigui Capsule could antagonize an increase in body weight and atrophy of the uterus of OVX rats. The estrogenic content and phosphoric level in serum increased significantly. Results of bone metaboism examination showed that the radioactive cound/weight(c/w t) increased. Conclusion: Compound Zigui Capsule had markedly effect on improvement of endocrine disorder, increase of weight, atrophy of the sexual organs and osteopenia in OVX rats.

Objective:To explore the clinical feature and prevention of delayed vitamin K deficiency in infants.Methods:The clinical data of 36 infants with delayed vitamin K deficiency who had been admitted to paediatric ward in our hospital during the last 4 years were analyzed retrospectively.Results:28 cases were cured with a cure rate of 77.78%;5 cases died with a mortality rate of13.89%;3 cases gave up treatment which accounts for 8.33%.Conclusion:The incidence rate of delayed vitamin K deficiency is high in infants on pure breastfeeding,and it could be prevented by periodical administration of supplementary vitamin K_1 in small doses to all infants from birth to 3 months.The early diagnosis and proper treatment of delayed vitamin K deficiency are of much clinical significance in increasing cure rate and reducing mortality rate.

Objective To investigate the spatiotemporal patterns and age-related changes of expression of type Ⅰ and type Ⅳ collagen in the corneal development of Bufo raddei larvae during metamorphosis.Methods Using immunohistochemical method,type Ⅰ and Ⅳ collagen distributions were investigated in the cornea of Bufo raddei at hind-limb bud stage,hind-limb developing stage,forelimb bud stage,complete metamorphosis stage,one-year-old adult and three-year-old adult,respectively.Results The inner and outer cornea fused together into mature cornea during metamorphosis.Type Ⅰ collagen was expressed widely during the period,it existed in Bowman's membrane,Descemet's membrane,corneal stroma and endothelium,especially showing a progressive change in corneal stroma.The expression of type Ⅳ collagen was only observed in Bowman's membrane and Descemet's membrane at first,since the forelimb bud stage,it also expressed in corneal stroma and endothelium,but it didn't express the same as Type Ⅰ.Conclusion Type Ⅰ collagen has the role in the construction of the corneal stroma and its fuction in the corneal development of Bufo raddei larvae during metamorphosis.Type Ⅳ and type Ⅰ collagen expressed differently in corneal stroma showing that the construction of the corneal stroma may depend partly on the right expression proportion of different collagen type.

The first-line chemotherapy with platinum-based regimens for 4 to 6 cycles is a standard care in advanced non-small cell lung cancer (NSCLC). However, for patients who got disease stabilization or maximal response after first line chemotherapy, how to choose safe and efficacy anticancer agents to extend first-line treatment and provide a better clinical benefit is deserving of more concerns currently. In this article,the clinical progress of the chemotherapy and molecular targeted agents as maintenance therapy for patients with advanced NSCLC is reviewed.

Atrioventricular septal defect (AVSD)is a frequently diagnosed congenital heart malformation affecting the atrioventricular valves and septa. Heart transcription factors play fundamental roles in atrioventricular valves development and atrioventricular septa formation. Now cardiac transcription factors ( GATA4, NKX2. 5,TBX5 ,ZIC3)have been identified to involve in the pathogenesis of AVSD in humans. Their abnormal expression or function change may cause atrioventricular valve and septa developmental anomalies. Here we review advances in the understanding of the relationship between these transcription factors and AVSD.

Objective To investigate the clinical efficiency and immune adjustment of oxymatrine capsule and acitretin in the treatment of psoriasis.Methods Eighty patients with psoriasis were randomly divided into treatment (T) and control (C) groups.The T group took orally oxymatrine one capsule (0.2g) three times a day and one acitretin (10 g) two times a day.The C group only took orally one acitretin (10 g) two times a day.The T and C groups were applied the same drug for external use.Moreover,another 40 normal volunteers were set as normal control group.The peripheral blood T cell subset CD3 +,CD4 +,CD8 +,CD4 +/CD8 + were detected in all the three groups (T,C,and normal) before and after treatment.Results The effective rate was 92.5％ in the T group,and 72.5％ in the C group with statistical significance (x2 =8.66,P ＜ 0.05).The symptom integral decline index of two groups before and after treatment has statistical significance (t =10.02,P ＜ 0.05).For the peripheral T cell subset CD3 +,CD4+,CD8 +,CD4 +/CD8 + in the T group,a significant difference was found between pretreatment and posttreatment [(57.13 ±8.14)％,(37.62 ±7.97)％,(33.01 ±2.97)％,(1.24 ±0.51)％ vs (60.09 ±11.53)％,(43.02±7.67)％,(25.63 ±4.24)％,(1.73 ±0.69)％,t =3.08 ～9.02,P ＜0.01].However,there was not any statistical significance between pretreatment and posttreatment in the C group (P ＞ 0.05).Conclusions The treatment of common psoriasis combined with oxymatrine capsule and acitretin had a good curative effect and it improved the imbalance of peripheral blood T cell subsets.
