AIM To investigate the anti-neuroinflammation effects of 4-hydroxybenzyl aldehyde (4-HBAL) from Gastrodia elata Blume on acute cerebral ischemic injury in rats and its nechanism of action.METHODS The rat model of acute cerebral ischemic injury was induced by injecting arachidonic acid via intracarotid artery.Brain tissue samples were taken from the animals 3 h after the model of acute cerebral ischemic injury.Tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) were detected in brain tissue to evaluate the effects of 4-HBAL in vivo.Lipopolysaccharid (LPS)-induced activation of BV-2 microglia cells model was used to explore the anti-neuroinflammation mechanism of 4-HBAL.RESULTS The experimental results showed that 4-HBAL had a significant protective effect on acute cerebral ischemic injury.It could significandy decrease the contents of tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β),and obviously inhibit the production of nitric oxide (NO),prostaglandin E2 (PGE2) and TNF-α in LPS-stimulated BV-2 cell,and increase the production of interleukin-10 (IL-10) and transforming growth factors-β (TGF-β) in BV-2 cell.CONCLUSION The mechanism of 4-HBAL may be related to the suppression of the excessive activation of microglia after cerebral ischemia and the promotion of the transformation of microglia into anti-inflammatory phenotype.

Objective:
This study aimed to determine the effect of radiotherapy (RT) on the risk of herpes zoster (HZ) in patients with gynecological cancers via a nationwide population-based study.
Methods:
Based on patient data obtained from the National Health Insurance Research Database, 1928 gynecological cancer patients were identified with 1:1 matching for RT and non-RT cohorts by age, index date, and cancer type. Another cohort consisting of 964 noncancer individuals matched was used as normal control. The incidence of HZ was compared between cancer patients with and without RT. Age, comorbidities, cancer-related surgery and chemotherapy (CT), and cancer type were adjusted as confounders.
Results:
The risk of HZ in cancer patients was higher than that of non-cancer individuals (14.23 versus 8.34 per 1,000 person-years [PY], the adjusted hazard ratio [aHR]=1.38, p=0.044). In the cancer population, the incidence of HZ for the RT and non-RT cohorts was 20.55 versus 10.23 per 1,000 PY, respectively (aHR=1.68, p=0.009). Age >50 years was an independent factor for developing HZ. The 5-year actuarial incidence for patients receiving neither RT nor CT, RT alone, CT alone, and combined modalities was 5.4%, 6.9%, 3.7%, and 9.9%, respectively (p<0.001). In the RT cohort, the risk rose rapidly in the first year, becoming steady thereafter.
Conclusion
This population-based study showed that gynecological cancer patients receiving RT combined with CT had the highest cumulative risk of HZ. Health care professionals should be aware of the potential toxicities.

The aim of this study was to investigate the expression of histone demethylase lysine specific demethylase1 (LSD1) in patients with acute leukemia (AL) and its clinical significance. LSD1 protein expression level was detected by semi-quantitative Western blot in HL-60 and SHI-1 leukemia cell line, in bone marrow mononuclear cells of acute AL patients with different condition [new diagnosis, complete remission (CR) and relapse] and in patients with non malignant hematopathy (control). Clinical data of AL patient followed up was collected. The relationship of LSD1 expression level with clinical prognosis was analyzed. The results showed that in HL-60 and SHI-1 leukemia cell line, LSD1 expression was strong positive, relative amount (LSD1/β-actin gray level rate) was 4.647 ± 3.840 and 1.628 ± 0.185 (n = 4) respectively. In 72 AL patients, LSD1 expression levels were quite different. LSD1 positive rate was 56.9% (41/72), average relative amount was 1.053 ± 1.976. In 17 controls, LSD1 positive rate was 0%, relative amount was 0.004 ± 0.012. The LSD1 positive rate in newly diagnosed AML or ALL group (90.4%, 77.8%) and refractory/relapse AML or ALL group (100%, 100%) was higher than that in AML or ALL CR group (4.7%, 0%) (p = 0.000), relative amount of LSD1 showed no statistically difference between newly diagnosed AML and ALL groups (1.177 ± 1.646, 1.275 ± 1.845) or refractory/relapse group (2.050 ± 2.470, 4.107 ± 3.676) and CR group (0.029 ± 0.033, 0.019 ± 0.024) (p > 0.05). In all AL patients, LSD1 positive rate in newly diagnosed (84.6%) and refractory/relapse groups (100%) was higher than that in CR group (3.8%). LSD1 relative amount in newly diagnosed group (1.274 ± 1.760), refractory/relapse group (3.359 ± 3.319) and CR group (0.027 ± 0.031) was higher than that in control group (p < 0.01), and in refractory/relapse group was higher than that in newly diagnosed group and CR group (p < 0.01), in newly diagnosed group was higher than that in CR group (p < 0.01). It is concluded that overexpression of LSD1 is correlated with refractory or relapse in AL. LSD1 expression level can reflect disease status of AL patients and may be a predictive biomarker for unfavourable prognosis of AL.

OBJECTIVETo investigate the expression of cyclooxygenase-2 (COX-2) in different prostate cancer (PCa) cell lines and its role in the acquisition of invasive and metastatic potentials of PCa.
METHODSWe detected the expressions of COX-2 in prostate cancer cell lines LNCaP, C4-2, IF11, IA8 and PC-3 with different metastatic potentials by Western blotting and RT-PCR, and analyzed their roles in the invasion and metastasis of different PCa cell lines.
RESULTSWestern blotting and RT-PCR showed that the expression of the COX-2 protein was high in PC-3, but absent in IF11, IA8, LNCaP and C4-2 (P < 0.05), and it was consistent with the expression of COX-2 mRNA.
CONCLUSIONCOX-2 expresses differently in PCa cell lines with different metastatic potentials. The overexpression of COX-2 may be associated with the high invasion and metastasis of PC-3, but not with the metastasis of other cell lines.

OBJECTIVETo evaluate the two-tier MDACC grading system for ovarian serous carcinoma by comparing with the WHO grading system, and to investigate the role of p53 immunostaining in ovarian serous carcinoma grading.
METHODS72 cases ovarian serous carcinoma of ovary were graded basing on the MDACC and WHO grading systems, respectively. Statistic analyses were made for the relationship between the data obtained from two grading systems and their clinical significance. All the cases were examined immunohistochemically by using antibody against p53 protein and the immunohistochemistry findings were analyzed with the two grading systems and clinical parameters.
RESULTSThere was a good correlation between the MDACC and WHO grading system (r=0.543, P=0.000). Neither system has a definite relationship with the disease-free survival time (P=0.170 vs. P=0.075), cytoreduction (P=0.478 vs. P=0.120), and the curative effect of platinum-based chemotherapy (P=0.418 vs. P=0.403). However, compared with the WHO grading system, MDACC grading system has a better correlation with tumor stage (P=0.041 vs. P=0.002), 3-year disease-free survival rate (P=0.077 vs. P=0.004), overall survival time (P=0.080 vs. P=0.046), and p53 immunohistochemistry results (P=0.334 vs. P=0.035). No significant difference was found between p53 immunohistochemistry results with other clinical characteristics and prognostic factors.
CONCLUSIONSCompared with the WHO system, the MDACC system showed a better prognostic value and was more likely correlated with the novel dualistic model for ovarian serous carcinogenesis. Although p53 immunostaining was valuable in assisting MDACC grading, it should be cautious to use it alone as an independent indicator in predicting the prognosis of ovarian serous carcinoma.

Objective To explore the value of CT guided ozone(O_3)injection in the ablation treatment of cervical spondylosis.Methods All 86 patients with cervical spondylosis including 37 myelopathy type,30 radiculopathy type,and 16 sympathetic type were treated with O_3 injection under CT guidance.The puncture rout was from the anteroparaline of neck to the disk.A total of (4?3)ml of O_3 with concentration 60?g/ml was injected into the disk and 10 ml of O_3 with concentration 40?g/ml was injected to the paraspinal tissue.Results After injection CT scan showed that O_3 was distributed within the disk and the protruding part as low-density air shadow in 37 myelopathy type and 30 radieulopathy type patients.O_3 was observed to spread in the anterior epidural space of spinal canal and the paraspinal tissue.Three months after 03 injection,67 patients (78% )showed excellent clinical efficacy,14 (16% )had good clinical efficacy,and 5 (6%)were poor respectively.Conclusion CT guided O_3 injection is an accurate,safe, and effective method in the treatment of cervical spondylosis.
