Paired box2 ( PAX2 ) is a transciption factor which mainly expressed in the developing kid-ney. Researches indicate that PAX2 promote the transcription through interactions with the adaptor PAX transac-tivation domain interacting protein(PTIP). Otherwise,PAX2 protein can lead to chromatin compaction and gene silencing through interactions with Grg4. PAX2 reexpressed in acute kidney injury and involved in promoting cell proliferation. Congenital PAX2 gene mutation is closely related to congenital abnormalies of the kidney and uri-nary tract. In chronic kidney disease,PAX2 promote proliferation and cyst formation. Here,the recent researches on the function of PAX2 and its role in acute kidney injury and chronic kidney disease are reviewed.

Objective: To investigate the in vitro and in vivo inhibitory effects of DC (dendritic cell)-CIK (cytokine-induced killer cell) co-cultured cells combined with sorafenib against hepatocellular carcinoma cell line BEL-7402. Methods: DC and CIK cells were generated in vitro by stimulating human peripheral blood mononuclear cells with different cytokines, and then they were co-cultured. The cytotoxicity of DC-CIK co-cultured cells (DC-CIK) combined with sorafenib against BEL-7402 cells was determined by CCK8 kit. The apoptosis of BEL-7402 cells was measured by Annexin V-FITC Kit. BEL-7402-implanted tumor model was established by subcutaneous injection in nude mouse. Tumor-bearing mice were divided into normal saline control group, sorafenib group, DC-CIK group and DC-CIK+sorafenib group. The inhibitory effects were observed in different groups. Results: The cytotoxicity rate of BEL-7402 cells in DC-CIK+sorafenib group was significantly higher than those in the other two groups, with cytotoxicity rate in DC-CIK+sorafenib group being (75.24±1.91)%, which was 1.8 times that in DC-CIK group and 2.1 times that in sorafenib group (P<0.01). The apoptosis rate of BEL-7402 cells in DC-CIK+sorafenib group was significantly higher than those in the sorafenib and DC-CIK groups, with the apoptosis rate in DC-CIK+sorafenib group being (78.32±2.54)% (P<0.05). The volume of tumor in the combination group was significantly smaller than those in the other groups (P<0.05). In vivo results showed that DC-CIK+sorafenib treatment significantly inhibited the growth of BEL-7402-implanted tumors, and the inhibitory rate was (83.37 ±0.16)%, which was significantly higher than those of the other groups (P<0.01). Conclusion:DC-CIK co-cultured cells combined with sorafenib can inhibit the growth of hepatocellular carcinoma cell line BEL-7402 in vitro and in vivo. Molecular targeting therapy combined with immunotherapy may be a new way for the comprehensive treatment of hepatocellular carcinoma.

Objective To compare curative effect of decompression and conservative treatment for traumatic superior orbital fissure syndrome to discuss the operation indications and the operative oppor-tunity for this syndrome. Methods Data of 12 patients (seven males and five females) with 14 sides were compared to evaluate different curative effect between decompression and conservative treatment so as to optimize the initial corresponding treatment. Results The patients were at mean age of 28 years and followed up for mean six months. All patients were complicated by one and more of following symptoms in-cluding ophthalmoplegia, ptosis, proptosis and anaesthesia in the distribution of V1 and a fixed dilated pupil. There was one patient complicated by orbital apex syndrome. CT showed involvement of the superi-or orbital fissure in seven patients. Of seven patients treated with decompression, six got recovery at dif-ferent degrees. Meanwhile, three out of five patients treated with conservative treatment recovered to some extent. Conclusions Early effective treatment can improve the functional rehabilitation of the injured nerve. Decompression of superior orbital fissure is proved to be effective in ameliorating symptome, re-ducing disability and improving quality of life.

Objective To evaluate the clinical efficacy of Qilinxintongshu pill for treatment of critical patients with unstable angina pectoris (UAP) accompanied by upper alimentary tract damage.Methods A prospective randomized controlled trial was conducted. A total of 60 critical outpatients or inpatients with confirmed diagnosis of UAP accompanied by upper alimentary tract damage in Cardiology Department of Hospital of Traditional Chinese Medicine of Qionghai City from November 2011 to January 2015 were enrolled in the study, and they were assigned to a therapy group (30 cases) and a control group (30 cases) by table of random number. The conventional medical basic therapy was given to both groups, in addition, the patients in therapy group took Qilinxintongshu pill (made of notoginseng, dragon's blood, fruit of immature citron, etc.) 5 g once, three times a day, and the patients in control group orally administered clopidogrel 75 mg once a day, the therapeutic course being consecutive 30 days. After treatment, the rates of main cardiovascular events [including death, a newly-happened myocardial infarction (MI), and obstinate ischemia] and events of alimentary damage were compared between the two groups, and adverse effects were observed.Results There was no statistically significant difference in incidence of cardiovascular events between the therapy group and control group [6.7% (2/30) vs. 16.7% (5/30),P > 0.05]. The incidence of massive hemorrhage of gastrointestinal tract was significantly lower in therapy group than that in control group [10.0% (3/30) vs. 36.7% (11/30),P < 0.05]. In the treatment process, there was no significant untoward side effect, and no abnormalities in routine blood and urine tests, liver and renal functions were found.Conclusion Qilinxintongshu pill for treatment of critical patients with UAP accompanied by upper alimentary damage is safe and effective, and does not enhance the incidence of massive hemorrhage of gastrointestinal tract.

BACKGROUND: Tumor-adopted immunity and gene transduction technique are used to introduce tumor necrosis factor-α vector into carrier cells, which are then re-infused into the body so that cancer cells can be killed by tumor necrosis factor-α more directly and effectively with fewer side effects on the other tissues due to high local expression.OBJECTIVE: To study the bioactivity of in vitro cultured tumor necrosis factor-α transduced tumor-infiltrating lymphocytes as well as the inhibitory effects on cancer cells of cancer-loaded rats infused in different ways.DESIGN: A randomized controlled study based on experimental animals.SEETING: Cancer Research Institute of China Medical University.MATERIALS: This study was carried out at the Cancer Research Institute and the Experimental Animal Department, China Medical University,between January 2000 and December 2001. TJ8510 cell line (human brain glioblastoma cell line) was provided by the Neurological Research Institute of Tianjin Medical University Affiliated Hospital. The experimental animals were 36 BALB/C nude mice congenitally having no thymius.METHODS: Based on the establishment of tumor necrosis factor-α retroviral transduction system and the preparation of cartier cells tumor-infil-trating lymphocytes, the monoclonal virus cell line PLC-2 and PLJC-5available were used to introduce marked gene NeoR and targeted gene tumor necrosis factor-α into tumor-infiltrating lymphocytes, respectively.Then cell proliferation, tumor necrosis factor expression and in vitro antitumor activity were examined. After cancer cell inoculation, the 36 nude mice were randomly divided into 6 groups: local infusion control group, local tumor-infiltrating lymphocytes infusion group, local tumor necrosis factor-tumor-infiltrating lymphocytes infusion group, venous infusion control group, venous tumor-infiltrating lymphocytes infusion group and venous tumor necrosis factor-tumor-infiltrating lymphocytes infusion group, and the therapeutic effects on the cancer-loaded mice were observed.proliferation and tumor necrosis factor-α expression in tumor-infiltrating oR-tumor-infiltrating lymphocytes and tumor necrosis factor-tumor-infiltrating lymphocytes was not significantly different from each other (P > 0.05).NeoR-tumor-infiltrating lymphocytes, though not significantly different (P >0.05), significantly differ from that of tumor necrosis factor-tumor-infiltrating lymphocytes (P < 0.01); moreover, tumor necrosis factor-tumor-infiltrating lymphocytes were found to express higher tumor necrosis factor-α conactivity did not significantly differ between tumor-infiltrating lymphocytes and NeoR-tumor-infiltrating lymphocytes (P > 0.05), but obviously increased come of the animal experiment: 40 days after tumor necrosis factor-tumorinfiltrating lymphocytes infusion, cancer size in local tumor necrosis factortumor-infiltrating lymphocytes infusion group was found smaller than that in local infusion control group [(307±42) and (2 048±278) mm3, P < 0.01],and it was also smaller in venous tumor necrosis factor-tumor-infiltrating lymphocytes infusion group than that in venous control group [(954±195)and (1 989±305) mm3 , P < 0.05].CONCLUSION: Tumor necrosis factor-α gene transduced tumor-infiltrating lymphocytes could effectively express tumor necrosis factor, exerting higher and in vivo anti-tumor effects than tumor-infiltrating lymphocytes in cancer-loaded nude mice. No obvious inhibitory effects on the growth of subcutaneous solid carcinoma could be observed in nude mice after venous infusion of human brain glioblastoma tumor-infiltrating lymphocytes, but the inhibitory effects became obvious due to venous infusion of tumor necrosis factor-tumor-infiltrating lymphocytes and significant due to local tumor necrosis factor-tumor-infiltrating lymphocytes infusion, indicating that local infusion is the preferable way in the treatment of glioblastoma by immuno-gene therapy.

Objective To discuss clinical effects of early (<48 hours after injury) fraeture exter-nal fixation in treatment of severe traumatic brain injury (TBI) combined with extremity fracture. Meth-ods The study involved patients with no statistical difference in aspects of age, sex, GCS, fracture ,distri-bution and general condition. According to different treatment methods at early stage (<48 hours), the pa-tients with TBI were divided into Group A (early extremity fracture external fixation) and Group B (early extremity fracture traction or cast immobilization). A comparative observation was done on complications in-cluding bedsore, pneumonia and deep venous thrombosis and on duration in ICU, hospitalization, time for fracture healing and mortality in two groups. Results Incidence rate of bedsore, pneumonia, deep ve-nous thrombosis and mortality in Group A was lower than that in Group B (P<0.05), and Group A had shorter time for ICU, hospitalization and fracture healing (P < 0.05). Conclusion For patients with se-vere TBI combined with extremity fracture, early fracture external fixation is more effective to reduce com-plications, shorten the recovery time and reduce mortality, compared with conservative methods.

Objective To investigate the relation between the expression of MICA/B in lung cancer cells and the mediastinum lymph node metastasis. Methods The samples of the lung cancer tissue as test group and the healthy tissue beside lung cancer as control group from 30 cases of patients with lung cancer were collected, and the expression of MICA/B on lung cancer cells surface were detected by flow cytometry.All patients were divided into three groups(N0, N1, N2) according to the state of lymph node metastasis, and the expression of MICA/B was analyzed among the three groups. Results The expression level of MICA/B in test group was significantly higher than that in control group[(0.3788±0.2398) %, (0.1908±0.1760) %] (P <0.01),however the MICA/B expression level between N0 and N1 or between N1 and N2 was not statistically different (P>0.05), while that between N0 and N2 had statistical difference (P<0.05). Conclusion The expression level of MICA/B on surface of lung cancer cells is high, and the MICA/B as ligand of NKG2D may play an important role in the tumor immune response. The expression of MICA/B in mediastinum metastatic lymph node from lung cancer is remarkably increased and the prognosis of patients with lymph node metastasis is poor. MICA/B could be considered as a marker of mediastinum lymph node metastasis.
