Interleukin-24 (IL-24) is a novel cancer suppressor cytokine. It can suppress cancer cell growth, induce cancer cell apoptosis, inhibit angiogenesis, stimulate the PBMC secretion of cytokines, and enhance the antitumor activity of radiotherapy, chemotherapy and targeting gene-virotherapy. It is reasonable to suggest that IL-24 may be a powerful and effective protocol for combinatorial cancer treatment in the clinic.

OBJECTIVE: We aimed to analyze the quality of life (QOL) in adults with allergic rhinitis according to the sensitization profile for relevant aeroallergens in Northern China, investigate the proportion of patients with coexisting asthma, and explore the correlation between QOL of rhinitis patients and the specific IgE level to the causative allergen. METHOD: One hundred and sixty-four allergic rhinitis patients participated in this study, whose clinical history, results of intradermal skin test and serum specific IgE levels to common aeroallergens in North China were collected. QOL was evaluated using the rhinoconjunctivitis quality of life questionnaire (RQLQ). RESULT: QOL of rhinitis patients was worse in those sensitized to tree pollens or weed pollens than those sensitized to house dust mites in Northern China. The proportion of patients with co-existing asthma was lower in tree pollen group than in house dust mite group or weed pollen group, and there was no significant difference between house dust mite group and weed pollen group. There was no significant correlation between QOL of rhinitis patients and the specific IgE level to the causative allergen. CONCLUSION In our study group, QOL of patients with allergic rhinitis varied with the allergen responsible for symptoms, but was not influenced by the specific IgE level to relevant allergen. The proportion of patients with co-existing asthma also varied with different pollen allergens. Rhinitis patients sensitized to weed pollens might be more likely to suffer from asthma than those sensitized to tree pollens.

[Objective]To explore the application value of vascularized fibular graft in the repairment of maxillofacial defects.[Methods] Forty-five patients with maxillofacial defects caused by various reasons were enrolled and treated by vascularized fibular graft.The related disease history,survival situation of blood vessels and tissue flaps of all the patients were recorded.[Results]All the patients were followed up for 3-6 months after surgery.All the patients could eat by mouth and without no obvious obstacle.There was no facial asymmetry,healthy side bite jaws deflection and so on.The maxillofacial appearance and functions almost returned back to normal.Oral panoramic radiography showed that the osseous healing of transplanted fibular and mandibular was good,and there was no bone nonunion,osteonecrosis,titanium plate rejection or fracture happened.Three-dimensional CT scàn revealed that the recovery of mandibular appearance was good.There was 1 case with leg wound drainage and 1 case with cervical wound effusion,which were all healed after the second phase by dressing change and necessary treatment.The rest of the patients were all healed at the first phase.There was no free tissue flap necrosis and calf obvious dysfunction.[Conclusions] Using vascularized fibular graft for the repairment of maxillofacial defects,the maxillofacial appearance and functions of patients almost return to normal after surgery.The surgery can satisfy the requirements of patients on postoperative oral and maxillofacial appearance and function with lower incidence of complications and hig her survival rate of free tissue flap.Therefore,it is worthy of clinical application.

BACKGROUND:The development of minimaly invasive technology significantly reduces the occurrence of surgical complications due to spinal metastases. Currently, the minimaly invasive treatment basicaly has three broad categories: vertebral cement augmentation, radiofrequency ablation combined with vertebroplasty, intraoperative radiotherapy combined with vertebroplasty. OBJECTIVE:To summarize the research progress of three kinds of minimaly invasive treatments for spinal metastases. METHODS:PubMed and Wanfang databases were searched using the keywords of spinal metastases, vertebroplasty, radiofrequency ablation, radiotherapy in English and Chinese, respectively. RESULTS AND CONCLUSION:Vertebral cement augmentation with good analgesic effect has been used widely, and the efficiency is up to 80%-90%. But its effect to kil tumors is very limited that is unable to control tumor growth. Radiofrequency ablation and radiation can kil the tumor, but cannot rebuild the vertebral stability. Therefore, the combination of different technologies can improve the therapeutic effect on spinal tumors. In recent years, intraoperative radiation and implantation of radioactive particles or radioactive bone cement have been developed as new technologies. However, there is no conclusion that these new technologies have better outcomes than the vertebral cement augmentation because of less reports and lack of long-term folow-up. Especialy in the metastatic patients with damaged vertebral posterior wal and tumors invaded into vertebral canal, the risk of nerve function damage caused by bone cement leakage is stil very high, even after many attempts. Above al, there is no a perfect minimaly invasive treatment for spinal metastases.

Objective To investigate the expressions of receptor for advanced glycation endproducts (RAGE) and nuclear factor κB(NF-κB) in brain hippocampus of rat with chronic fluorosis,and to reveal the mechanism of brain damage resulted from chronic fluorosis.Methods Sixty clean grade SD rats were randomly divided to three groups(20 rats in each group,10 female and 10 male) fed with different contents of fluoride,control group with normal tap-water(＜ 0.5 mg/L fluoride),small dosage of fluoride exposure group(10 mg/L fluoride in tap-water) and large dosage of fluoride exposure group(50 mg/L fluoride) for six months.Then the rats were killed by femoral artery bleeding and hippocampus was removed.Protein and mRNA levels of RAGE and NF-κB in the hippocampus were determined by Western blotting and quantitative real time PCR,respectively.Results As compared to the control groups[(100.00 ± 2.60)％,(100.00 ± 7.80)％],the expressions of RAGE and NF-κB at protein level in the hippocampus were significantly increased in the small dosage of fluoride exposure groups [(205.00 ± 15.30)％,(156.00 ± 12.20)％] and the large dosage of fluoride exposure groups[(232.00 ± 10.90)％,(162.00 ± 9.80)％,all P ＜ 0.05]; for the mRNA level of RAGE and NF-κB,the expressions were higher in the small dosage of fluoride exposure groups(1.27 ± 0.09,0.83 ± 0.15) and the large dosage of fluoride exposure groups (2.60 ± 0.19,1.27 ± 0.19) than those of the control groups(0.66 ± 0.18,0.32 ± 0.08,all P＜ 0.05).Conclusions The increased expressions of RAGE and NF-κB in the hippocampus of rat brain are caused by chronic fluorosis,and these changes may be associated with the mechanism of nerve injury.

Objective Aim of the study is to investigate the expression of syndecan-4 and nuclear factor κB(NF-κB) in the kidney of rat with chronic fluorosis,and to reveal the mechanism of kidney damage resulted from the toxicity of excessive amount of fluoride.Methods According to body mass and sex,sixty SD rats were randomly divided to three groups according to body mass and fed with different contents of fluoride:control group with normal tap-water(＜ 0.5 mg/L fluoride),small dosage of fluoride exposure group (adding 10 mg/L fluoride in tap-water) and large dosage of fluoride exposure group (50 mg/L fluoride) for six months.The protein level of syndecan-4 and NF-κB in the kidney was detected by Western blotting and syndecan-4 mRNA level by quantitative real time PCR.Results As compared to the control group[(100.0 + 8.1)％],the expression of syndecan-4 at protein level in the kidney of rat was significantly increased in the small dosage of fluoride exposure group [(198.5 + 5.6)％,P ＜ 0.05] and large dosage of fluoride exposure group [(209.2 + 13.0)％,P ＜ 0.05]; the protein levels of NF-κB in the small dosage of fluoride exposure group[(284.4 + 11.1)％,P ＜ 0.05] and in the large dosage of fluoride exposure group[(343.2 + 2.9)％,P ＜ 0.05] were significantly increased than that of the control group[(100.0 ± 10.7)％].The mRNA levels of syndecan-4 in the kidney in the small dosage of fluoride exposure group and large dosage of fluoride exposure group(0.431 + 0.058 and 0.453 ± 0.065,both P ＜ 0.05,respectively) were significantly increased than that of the control(0.128 + 0.026).Conclusions The increased expression of NF-κB in the kidney is induced by increased expression of syndecan-4,which may be involved in kidney damage of chronic fluorosis.

Objective To study the relationship between serum Treg cells content and superoxide dismutase(SOD) level with the severity and clinical prognosis in the patients with preeclampsia.Methods Forty cases of preeclampsia in our hospital from September 2015 to September 2016 were selected as the research subjects divided into the mild preeclampsia group(25 cases) and severe preeclampsia groups(15 cases) according to the disease severity,and 20 healthy pregnant women served as the control group.The peripheral blood Treg cells and serum SOD level were compared between the two groups.The relationship between Treg cell content and serum SOD level with the disease severity and prognosis in the patients with preeclampsia was investigated.Results The systolic and diastolic blood pressure in the severe preeclampsia group were(145.3±10.6)mm Hg and(102.3±7.8)mm Hg,the occurrence rates of premature delivery,placental abruption and fetal distress were 33.3%,20.0% and 13.3% respectively,BMI before pregnancy was 25.4±1.3,which were significantly higher than those in the mild preeclampsia group and control group,while the mild preeclampsia group was higher than the control group.The Treg cell content and SOD level in the severe preeclampsia group were (2.3±0.7)×106/L and(2.6±0.7)μg/mL,which were significantly lower than those in the mild preeclampsia group and control group and which in the mild preeclampsia group were (3.4±0.6)×106/L and(4.3±0.9)μg/mL,and significantly lower than those in the control group,the differences were statistically significant(P<0.05).The Logistic regression analysis results indicated that BMI index(P=0.018),Treg cell content(P=0.024) and SOD level(P=0.029) were the independent risk factors for poor pregnancy outcome.Conclusion The peripheral blood Treg cells content and serum SOD level are closely related to poor pregnancy outcome in the patients with preeclampsia.

Objective To investigate the effect of tumor necrosis factor alpha ( TNF-?) in combination with Go6976 on murine liver cancer cells (H22). Method H22 cells were divided into two groups. Each group was further divided into four subgroups. Group 1 was treated with TNF-? 0, 20, 40, 60ng/ml. Group 2 was treated with TNF-? 0, 20, 40, 60 ng/ml and Go6976 (4.6 nmol/ml). The apoptotic rate, protein kinase C alpha (PKC-?) expression and phosphorylation-PKC-? (p-PKC-?) were detected by flow cytometer and Western blotting respectively in 4 h, 8 h and 16 h. Result Treated with TNF-? (0, 20, 40, 60 ng/ml) for 4 h, the apoptotic rates of H22 cells were 2. 44% ? 0. 31 % , 1. 80% ? 0. 32% , 2. 73% ?0. 14% and 3. 05% ?0. 78% respectively, with no change on the expression of PKC-? and p-PKC-?; For 8 h, the expressions of PKC-? and p-PKC-? in H22 cells were up-regulated with increasing concentration of TNF-?; When PKC-? was inhibited with Go6976 at the same time, the apoptotic rates of cells increased significantly, being 2. 90% ?0.39%, 7.76% ?0.35%, 11.43% ?1.05% and 12.96% ?2.44% , respectively. Moreover, PKC-? and p-PKC-? were down-regulated accordingly. When H22 cells were treated with TNF-? only or combined with Go6976 for 16 h, the result was similar to that of 8 h; The apoptotic rate dropped in the group in which PKC-? was inhibited by Go6976 with TNF-? at 60 ng/ml, but the proportion of necrotic cells increased. Conclusion TNF-? up-regulates the expression of PKC-? and p-PKC-? in H22 cells. Inhibiting the activity of PKC-? significantly enhances the toxicity of TNF-? to H22 cells.
