?AlM:To observe the eye complications in the cases of acute chlorine gas poisoning.
?METHODS:A retrospective review of 121 cases of acute chlorine gas poising with eye irritation, dry eye and other eye complications in Linyi People’s Hospital from February 2009 to February 2013 was performed.
?RESULTS: Among 121 patients, 117 cases ( about 96. 7%) had complications of eye irritation and conjunctival and corneal epithelial damage, and the ocular surface damage was aggravated with the increasing level of chlorine gas poisoning. After 3, 6mo being discharged, 32 and 7 patients respectively occurred dry eye among 115 patients followed up. One mild chlorine poisoning patient, during the hormonotherapy of pulmonary complication, complicated with bullous retinal detachment, of which symptoms and physical signs had been improved after stopping hormonotherapy and adding drugs facilitating fluid absorption. One severe chlorine poisoning patient with loss of consciousness during the treatment, had corneal ulcer and after ulcer being healed with drug and conjunctival flap covering surgery, was left permanent leukoma cornea.
?CONCLUSlON: Acute chlorine poisoning can cause corneal and conjunctival epithelial damage and dry eye. Ocular complications like bullous retinal detachment associated with hormone application should be paid more attention to in the hormonotherapy. For some patients with severe poisoning, the therapy of corneal and conjunctival epitheliums should be taken seriously in case of irreparable damage in rescuing patient’s life.

Salvia miltiorrhiza is a highly valued traditional chinese medicine for the treatment of atherosclerosis-related disorders in china, such as cardiovascular and cerebrovascular diseases in China. The wilt disease is serious in the culture of S. miltiorrhiza. Wilt disease cause biomass of plant shoots and roots is lessened, active components are decreased. To solve these problems, we research the pathogen causing wilt disease of S. miltiorrhiza. The suspected pathogen is identified by morphology and etiological test. The identification was further confirmed by alignment the sequences of internal transcribed spacer (ITS) amplified by PCR. Our result show the wilt disease of S. miltiorrhiza mostly occurred in July and August, which is hot and wetter. The wilt disease rate of S. miltiorrhiza continuous cropping for one year in S. miltiorrhiz stubble is 10%, but the wilt disease rate of S. miltiorrhiza continuous cropping for three years in S. miltiorrhiz stubble is 60%-70%. The root rot of S. miltiorrhiz caused by the wilt disease, so the wilt disease was mistaken for the rot root in production. Morphological characteristics show the pathogen is Fusarium oxysporum. The sequence of ITS wes determined and found by BLAST shared 99% identity to that of F. oxysporum f. sp. cucumerinum. So it comes to the conclusion that the causing agent of wilt disease on S. miltiorrhiza belongs to F. oxysporum.

Orthodenticlehomeobox 1 (OTX1) overexpression had previously been associated with the progression of several tumors. The present study aimed to determine the expression and role of OTX1 in human hepatocellular carcinoma (HCC). The expression level of OTX1 was examined by quantitative real-time PCR (qRT-PCR) in 10 samples of HCC and paired adjacent non-cancerous tissues, and by immunohistochemistry (IHC) analysis in 128 HCC samples and matched controls. The relationship between OTX1 expression and the clinicopathological features werealso analyzed. Furthermore, the effects of OTX1 knockdown on cell proliferation and migration were determined in HCC cell lines. Axenograft mouse model was also established to investigate the role of OTX1 in HCC tumor growth. TheqRT-PCR and IHC analyses revealed that OTX1 was significantly elevated in HCC tissues compared with the paired non-cancerous controls. Expression of OTX1 was positively correlated with nodal metastasis status (P = 0.009) and TNM staging (P = 0.001) in HCC tissues. In addition, knockdown of OTX1 by shRNA significantly inhibited the proliferation and migration, and induced cell cycle arrest in S phase in vitro. Tumor growth was markedly inhibited by OTX1 silencing in the xenograft. Moreover, OTX1 silencing was causable for the decreased phosphorylation level of ERK/MAPK signaling. In conclusion, OTX1 contributes to HCC progression possibly by regulation of ERK/MAPK pathway. OTX1 may be a novel target for molecular therapy towards HCC.

OBJECTIVETo examine the activation and cytotoxicity of human peripheral blood T lymphocyte induced in vitro by human 4-1-BB ligand (4-1-BBL) gene transfected into tumor Tca8113 cells.
METHODSThe eukaryotic expression vector pEGFP-h4-1-BBL was transfected into human oral carcinoma cell line Tca8113 by Lipofectamine 2000. The transfected cells were then selected in medium containing G-418, cloned by limited dilution and named as Tca8113-4-1-BBL. Human 4-1-BBL mRNA and protein expression of transfected cells was detected by reverse transcriptase-polymerase chain reaction (RT-PCR) and western blotting respectively. The tumor cell vaccines (TCV) were obtained by treatment with mitomycin (MMC). Human peripheral blood mononuclear cells (PBMC) were prepared from lymphoprep, and then stimulated with anti-CD-3 mAb and incubated with non-transfected or transfected TCV-Tca8113 cells, respectively. The proliferation of T cells was evaluated by trypan blue exclusion; the CCK-8 was used to detect the cytotoxic effect of T lymphocytes. Meanwhile, the secretion of interferon-gamma (IFN-gamma) and interleukin (IL)-2 in culture supernatant was detected by enzyme-linked immunosorbent assay (ELISA).
RESULTSThe Tca8113 cells transfected by pEGFP-h4-1-BBL could express human 4-1-BBL efficiently. As compared with wild type Tca8113 cells, the transfected Tca8113 cells could markedly promote proliferation, IL-2 and IFN-gamma production and cytotoxic activity of lymphocytes.
CONCLUSIONSThe transfection of human 4-1-BBL gene in Tca8113 cells is effective in enhancing its immunogenicity and inducing antitumor immune response in vitro.

OBJECTIVETo observe the incidence of heparin-induced thrombocytopenia (HIT) in patients received unfractionated heparin (UFH) treatment, and explore the feasibility of monitoring HIT by platelet counts, as well as the significance of HIT-antibody test in HIT diagnosis.
METHODS145 patients received UFH treatment in Vascular Surgery Department were studied. Before and after the UFH treatment, platelet counts, HIT-antibody ELISA test and heparin-induced platelet aggregation (HIPA) were tested.
RESULTSAmong the 145 patients, thrombocytopenia occurred in 40 (27.6%) cases, HIT-antibody ELISA test positive in 59 (40.7%) cases, HIPA test positive in 26 (17.9%) cases. The HIT was diagnosed in 24 (16.5%) cases, and heparin-induced thrombocytopenia and thrombosis (HITTS) occurred in 5 (3.4% in all cases, and 20.8% in HIT patients). In HIT patients, 15 patients (62.5%) were thrombocytopenia, HIT-antibody positive and HIPA test positive. Platelet counts in all of the 24 patients recovered to normal or level before UFH treatment in 3-6 days after heparin withdrawal therapy.
CONCLUSIONHIT can be early diagnosed by monitoring platelet counts, HIT-antibody ELISA test and HIPA test. Withdrawal of heparin therapy in time and use of alternative anticoagulant, HITTS rate might be expected to decline further.

OBJECTIVETo investigate the effects of drug-containing serum of Chinese herbal compound, Xiongshao Capsule (, XS, for activating-blood) and Huanglian Capsule (, HL, for dispellingtoxin) on the oxidized low-density lipoprotein (ox-LDL)-induced inflammatory factors in human umbilical vein endothelial cells (HUVECs).
METHODSThirty-two rats were randomly divided into four groups: the blank control group treated with distilled water, the positive control group treated with simvastatin (1.8 mg/kg), the test group I treated with Chinese herbal compound of XS (0.135 g/kg), and the test group II treated with Chinese herbal compound of XS (0.135 g/kg) and HL (0.135 g/kg). All the treatments were administered for 7 successive days by gastrogavage. Rats' blood serum was harvested 1 h after the last administration to prepare respective drugcontaining serum. HUVECs were exposed to ox-LDL (100 μg/mL) to induce cell injury model and incubated with corresponding drug-containing serum for 24 h. Untreated HUVECs were set for blank control. Levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and soluble intercellular adhesion molecule-1 (sICAM-1) in supernatant of cultured HUVECs were determined by enzyme-linked immunosorbent assay (ELISA). HUVEC surface expressions of ICAM-1 and E-selectin were determined by flow cytometry.
RESULTSLevels of IL-6, TNF-α, and sICAM-1 in the supernatant of HUVECs as well as the cell surface expressions of ICAM-1 and E-selectin significantly increased after 24-h ox-LDL stimulation (P<0.01), while the abnormal elevations, except sICAM-1 in the test group I, were all reduced in the treated groups (the positive control and the two test groups) significantly (P<0.01 or P<0.05). Besides, the effect in the test group II seemed somewhat higher than that in the test group I but with no statistical significance (P>0.05).
CONCLUSIONDrug-containing serum of XS plus HL has a certain inhibitory effect on the vascular endothelial inflammation response induced by ox-LDL.

Objective To investigate the infection rate of human papillomavirus(HPV)among pregnant women, and to explore the effect of HPV infection on adverse pregnancy outcome. Methods A total of 1 679 pregnant women in hospital were collected for the research. The flow-through hybridization and genechip(HybriMax)method was used to detect the infection of HPV. Univariate analysis was used to analyze the factors affecting HPV infection in pregnant women. The binary logistic analysis was used to analyze risk factors affecting adverse pregnancy outcome. Results HPV infection rate was 31.39%(527/1 679), including 14.23%(239/1 679)of HR-HPV, 15.54%(261/1 679)of LR-HPV and 1.61%(27/1 679)of mixed of HR-HPV and LR-HPV. Univariate analysis showed that there was significant difference in initial sex age, education level and smoking history between infection group and non-infection group, with statistical difference(P<0.05). The incidence rate of adverse pregnancy outcomes in infection group(31.50%) was significant higher than that of non-infection group(9.81%), with statistical difference(P<0.01). The incidence rate of premature rupture of fetal membranes, newborn respiratory papillomatosis and other adverse pregnancy outcomes among HR-HPV group, LR-HPV group and mixed group had no significant difference (P>0.05). Binary logistic regression analysis showed HR-HPV infection(OR=4.194, 95% CI: 3.099-5.675), LR-HPV infection(OR=1.771, 95%CI: 1.288-2.434)and mixed type infection(OR= 3.350, 95%CI: 1.630-7.735)were the risk factors affecting adverse pregnancy outcome(P<0.01), however, age and times of gestation had no statistical significance in the binary logistic analysis(P>0.05). Conclusion HPV infection was the risk factors for adverse pregnancy outcome, which indicated that screening work in pre-pregnancy and pregnancy, and persisting in early prevention, early detection and early treatment could reduce the incidence rate of adverse pregnancy outcome.

ObjectiveTo explore the effect of Chaishao Liujuntang on Hedgehog signaling pathway in rats with chronic atrophic gastritis (CAG) of liver depression and spleen deficiency. MethodWistar rats were randomized into normal group and modeling group. CAG with the liver depression and spleen deficiency syndrome was induced in rats in the modeling group with a compound method. After modeling, they were classified into the model group, vitacoenzyme group, Chaishao Liujuntang group, GDC-0449 (blocker) group, and Chaishao Liujuntang + GDC-0449 group. Normal group and model group were given (ig) normal saline. Vitacoenzyme and Chaishao Liujuntang group received (ig) corresponding drugs at 240 mg·kg-1·d-1 and 5.1 g·kg-1·d-1, respectively, and GDC-0449 group was treated (ip) with GDC-0449 at 50 mg·kg-1·d-1. For the Chaishao Liujuntang + GDC-0449 group, rats received GDC-0449 (ip) at 50 mg·kg-1·d-1 and Chaishao Liujuntang (ig) at 5.1 g·kg-1·d-1. The administration lasted 4 weeks. The pathological morphology of rat gastric mucosa was observed based on hematoxylin-eosin (HE) staining. mRNA and protein expression of sonic hedgehog (Shh), 12th transmembrane receptor Patched1 (Ptch1), and glioma-associated oncogene homolog 1 (Gli1) in gastric mucosa tissues was detected by real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) and Western blot. Content of serum interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) was determined by enzyme-linked immunosorbent assay (ELISA). ResultCompared with normal group, the model group demonstrated decrease in gland cells, glandular atrophy, large lumen volume, plasma cell infiltration, intestinal metaplasia, decrease in the mRNA and protein expression of Shh, Ptch1, and Gli1 in gastric mucosa (P<0.01), and rise of serum IL-1β and TNF-α content (P<0.01). Compared with model group, vitacoenzyme group and Chaishao Liujuntang group showed ordered cells, alleviation of gland atrophy, and no obvious inflammatory infiltration, and GDC-0499 group and Chaishao Liujuntang + GDC-0449 showed no significant improvement. Significant rise in the mRNA and protein expression of Shh, Ptch1, and Gli1 in gastric mucosa tissues of vitacoenzyme group and Chaishao Liujuntang group (P<0.01), no significant difference in serum IL-1β content and significant decrease in TNF-α content in vitacoenzyme group (P<0.01), significant reduction in content of serum IL-1β and TNF-α in Chaishao Liujuntang group (P<0.05, P<0.01) were observed compared with those in the model group. The mRNA and protein expression of Shh, Ptch1, and Gli1 in gastric mucosa and the content of serum IL-1β and TNF-α were insignificantly different between the GDC-0449 group and Chaishao Liujuntang + GDC-0449 group. ConclusionChaishao Liujuntang can effectively improve the pathological state of gastric mucosa in CAG rats with liver depression and spleen deficiency, which may be related to the activation of Hedgehog signaling pathway and the decrease of IL-1β and TNF-α content.
