Objective To analyze the relationship between serum HBV-DNA and hepatic fibrosis in patients with hepatitis B. Methods Serum HBV-DNA load and hepatic fibrosis hyaluronic acid (HA),Ⅲ procollagen N terminal peptide(PⅢNP),laminin (LN),Ⅳ collagen(Ⅳ-C)of 154 cases were detected by real-time fluorescence quantitative PCR and chemiluminescence method. Statistical analysis of the correlation between HBV-DNA load and hepatic fibrosis indicator was performed.Results The data of HBV-DNA load after taking lg value was 5.49±1.39;The serum concentration of hepatic fibrosis HA was (166.95±148.20)ng/mL,PⅢNP was (12.14±7.37)ng/mL,Ⅳ-C was (65.29±45.48)ng/mL,LN was (59.52±35.67)ng/mL.The difference between experimental group and control group in hepatic fibrosis was significant(P <0.05).Serum HBV-DNA only correlated with LN(r=0.284,P =0.015).Conclusion There is no significant correlation between serum HBV-DNA and hepatic fibrosis in hepatitis B pa-tients.Anti-fibrosis treatment should also be strengthened for hepatitis B patients in the course of antiviral treatment.

Objective To observe the protective effect of erythropoietin (EPO) on anoxia of motoneurons after spinal cord injury in rats.Methods The motoneuron was dissociated from neonate Wistar rats and cultivated in vitro with deprivation of oxygen in the medium. The changes of morphology were observed by phase-contrast microscopy, and the expression of EPO receptor (EPOR) was detected with Western blotting. The survival rate of motoneuron was measured with methyl thiazolyl tetrazolium (MTT) assay, and the level of lactate dehydrogenase (LDH) was observed. Results Compared with the control group, the expression of EPOR and the level of LDH increased (P<0.01),and the survival rate of motoneuron decreased (P<0.01) in the anoxia group. Compared with the anoxia group, the expression of EPOR and the level of LDH decreased (P<0.05), and the survival rate of motoneuron increased (P<0.01) in the EPO group, which was related with the level of EPO. Conclusion EPO could relieve the damage of motoneuron caused by anoxia, especially by upregulating EPOR.

Objective To semiquantify salivary gland damage after 131I treatment in patients post thyroidectomy using salivary gland scintigraphy. Methods Fifty-six patients underwent salivary gland scintigraphy 6 months after 131I ablation therapy following thyroidectomy, including 21 with both baseline (before 131I treatment) and follow-up (6 months after the 1st 131I treatment) imaging. Salivary gland function was quantified by uptake ratios at 4 minutes (UR4) and 15 minutes (UR15), and excretory index at maximum secretion (MS), time duration from stimulation to minimum count (Tmin ). Paired t test was used for the 21 patients with both baseline and follow-up imaging. All the studies were divided into four groups: before 131I therapy, after 1st therapy, after 2nd therapy, and after 3rd or more times of therapy. Group differences were evaluated by the one-way analysis of variance (ANOVA)/Kruskal-Wallis test. Spearman test was used to analyze the correlation between the parameters and times of therapy. Results After the 1st 131I therapy, UR15 for the left and right parotid glands were 16% and 14% lower than the baseline, respectively (t=2.188, 3.322, both P<0.05). All the other parameters were not significantly different from those of baseline (t: -0.952 to 2.039, all P>0.05). Among the four groups, significantly different parameters for both parotid glands were found: UR4, UR15, MS for the left parotid of the four groups were 1.76±0.29, 2.60±0.38, (72.8±24.2)%; 1.55±0.34, 2.15±0.51, (64.4±21.6)%; 1.55±0.40, 2.02±0.68, (57.2±34.2)%; 1.45±0.33, 1.69±0.46, (30.6±36.9)%; respectively (F values for UR4 and UR15 were 7.018, 3.112 and H value for MS was 12.240, all P<0.05). UR4, UR15, MS for the right parotid were 1.81±0.33, 2.57±0.51, (69.1±18.5)%; 1.61±0.38, 2.19±0.59, (64.2±25.0)%; 1.60±0.42, 2.00±0.62, (53.2±41.7)%; 1.48±0.38, 1.63±0.29, (26.1±45.9)%, respectively (F=13.393,10.194,H=26.569,all P<0.05). However, no statistical differences were P>0.05). According to pair-pair comparison, only the degree of reduction of UR15 for parotid glands was significantly different between the 1st and 2nd therapy (P<0.05). UR4, UR15, MS for bilateral parotid glands reduced significantly after 3 or more times of therapy (all P<0.05).The parametres UR4, UR15, MS were correlated with times of 131I therapy (r:-0.296 to -0.566, all P<0.05). Conclusions Salivary uptake function is impaired slightly after the 1st radioiodine therapy. After several times of therapy, both parotid uptake and excretion functions are impaired. Submandibular functions are not affected even after repeated 131I therapy.

Objective To explore the mechanism of anti-tumor effects of transferring tumor-specif-ic lymphocytes obtained from pre-immunized BALB/c mice with inactive rolL-21 tumor vaccine (mIL-21-Sp2/0)to syngeneic mice, associated with mIL-21 tumor vaccine immunization, in the condition of cyclo-phosphamide (Cy)-induced lymphopenia. Methods Activated lymphocytes of spleen and lymph nodes ob-tained from pre-immunlzed syngeneic mice with irradiated mIL-21-Sp2/0 cells were infused into BALB/cmice treated with Cy 2 days before, subsequently vaccinated with mlL-21 tumor vaccine, after 7 days, chal-lenged with Sp2/0 tumor cells, observed the growth of tumor of mice. T lymphocyte subsets differentiation was measured by flow cytometry (FCM) analysis. The proliferation and cytotoxie activities of activated lym-phocytes were analyzed by FCM, respectively, staining with CFSE and 7-AAD. The number of IFN-γ-secre-ting cells was evaluated by ELISPOT. Results The lymphopenic mice were transferred with activated lym-phocytes and inoculated with raiL-21 tumor vaccine might provide superior anti-tumor immunoprotection, re-tard tumor growth of the mice. The proliferating capabilities and killing rate of transferred tumor Ag-specific lymphocytes enhanced obviously, the number of IFN-γ-secreting cells was significantly higher compared with the control groups. Conclusion Under Cy-induced lymphopenia condition, tumor Ag-specific lymphocytes sensitized by raiL-21 tumor vaccine were transferred to mice and immunized with mlL-21 tumor vaccine at the same time, benefit the proliferation of transferred effective cells and immune cells itself, assist to form and sustain special anti-tumor effects.

Objective To evaluate the olfactory functions in patients with Parkinson's disease (PD) with a smell identification test developed for the Chinese population and to examine possible factors contributing to PD patients' olfactory performance.Methods Fifty-five patients with idiopathic and nondementia PD and 55 demographically matched healthy controls (HC) were recruited and their olfactory identification tested using the Chinese Smell Identification Test developed by the Institute of Psychology at Chinese Academy of Sciences.Results Olfactory identification score was significantly lower (t =-6.827,P＜0.01) in the PD group (19.3 ±5.4) as compared with the HC group (26.5 ±5.7).Of all PD patients,63.6％ scored over 1 SD below the age norm.In particular,of those with Hoehn-Yahr ratings between 2 to 3,77.8％ scored over 1 SD below the age norm.Receiver operating characteristic (ROC) curve analysis indicated that a cut-off score of 22.5 on the Chinese Smell Identification Test distinguished between PD patients and HC with a sensitivity of 74.6％ and specificity of 70.9％.Within the PD group,age,education,Hoehn-Yahr rating and Mini-Mental State Examination score were not found to correlate with olfactory performance (all P ＞ 0.05).Conclusion PD patients in China show significant impairment of olfactory identification,which is effectively captured by the Chinese Smell Identification Test.

AIM: To explore whether strontium ranelate ( Sr ) promotes osteogenic differentiation of rat bone mesenchymal stem cells (BMSCs) through the Hedgehog/Gli1 signaling pathway.METHODS:BMSCs were isolated from 4-week-old rats by adherent culture and induced to differentiate into osteoblasts .According to the experimental purposes , the cells were exposed to different concentrations of Sr , cyclopamine ( Cy, an inhibitor of Hedgehog receptor ) or Gli1-siR-NA.The expression of Gli1 and Runx2 in the cells was detected by Western blotting .The activity of alkaline phosphatase ( ALP) was measured by the method of colorimetry , and the mineralized nodules were observed under microscope with aliz-arin red staining .RESULTS:Exposure to Sr at concentrations of 0.1 to 5 mmol/L for 7 d markedly increased the expres-sion of Gli1 in the BMSCs , and the increase in Gli1 expression was the most obvious following Sr exposure at concentration of 3 mmol/L.Cy at concentration of 10 μmol/L inhibited Sr-induced up-regulation of Gli1 expression.Transfection of the BMSCs with Gli1-siRNA not only obviously inhibited Sr-induced up-regulation of Gli1 and Runx2 ( a downstream protein of Gli1) expression, but also antagonized Sr-induced enhancement of ALP activity and the formation of mineralized nodules . CONCLUSION:The Hedgehog/Gli1 pathway is involved in Sr-induced osteogenic differentiation of rat BMSCs .

Objective To evaluate the efficacy of extended-field intensity-modulated radiotherapy (IMRT) in the treatment of patients with early-stage NK/T cell lymphoma (NKTCL),and to examine the clinical characteristics and the effect of treatment factors on the prognosis of these patients.Methods The clinical data of 165 patients with early-stage NKTCL who underwent extended-field IMRT with (n=158,95.8%) or without chemotherapy (n=7,4.2%) were reviewed.Of these 165 patients,140(84.8%) received a radiation dose of ≥50 Gy to the primary lesion,and 25 patients (15.2%) received a radiation dose of<50 Gy.Most patients (n=147,89.1%) were treated with L-asparaginase-based chemotherapy regimens,whereas only 11 patients (6.7%) were treated with doxorubicin-based CHOP/CHOP-like regimens.In addition,109 patients (66.1%) received ≥4 cycles of chemotherapy.Locoregional control (LRC),overall survival (OS),and progression-free survival (PFS) rates were calculated using the Kaplan-Meier method,and the log-rank test was used for survival comparison and univariate prognostic analysis.A multivariate prognostic analysis was performed using the Cox model.Results The 5-year sample size 55.The 5-year OS,PFS,and LRC rates of all patients were 74.2%,72.5%,84.4%,respectively.The patients who received a dose of ≥50 Gy had a significantly higher 5-year LRC rate than those with<50 Gy (91.8% vs.39.7%,P=0.000).The 5-year OS was significantly higher in the low-risk early-stage group than in the high-risk early-stage group (P=0.002).For the high-risk early-stage NKTCL group,patients who received ≥4 cycles of chemotherapy had significantly higher 5-year OS and PFS than those who received<4 cycles of chemotherapy (5-year OS:71.3% vs.59.5%,P=0.032;5-year PFS:70.4% vs.54.4%,P=0.009).In addition,multivariate analysis showed that ECOG≥2,primary tumor invasion (PTI),and Ann Arbor stage Ⅱ were associated with poor OS (P=0.006,0.002,0.014),and ECOG≥2 and PTI were associated with reduced LRC (P=0.004,0.016).Furthermore,ECOG≥2,PTI,Ann Arbor stage Ⅱ,and extranasal primary site were associated with lower PFS (P=0.045,0.003,0.030,0.032).Conclusions Extended-field IMRT at a dose of ≥50 Gy can lead to favorable LRC,OS,and PFS in patients with early-stage NKTCL.However,it is less effective against distant early-stage NKTCL in patients with poor prognosis.Nevertheless,≥4 cycles of chemotherapy can significantly improve the OS and PFS of patients with early-stage NKTCL.

Hypoxia is one of the most important characteristics of malignant tumor microenvironment, and its degree is closely related to the development and prognosis of the tumor. Hypoxia promotes neovascularization in tumor microenvironment, which leads to changes of energy metabolism and the formation of drug tolerance in tumor. Studies in recent years have shown that TCM can interfere with the occurrence and development of hypoxia tumor microenvironment in certain aspects, thus inhibiting tumor growth. This article summarized recent studies on the etiology, pathogenesis, and TCM intervention for the occurrence and development of hypoxia tumor microenvironment in terms of spleen deficiency, blood stasis, and phlegm retention, and provided a reference for clinical intervention of tumors and research and development of new drugs.
