Objective To investigate the expressions of CD147,MMP-9 and TIMP-1 in human gliomas and analyze the correlations.Methods Expressions of CD147,MMP-9 and TIMP-1 were assessed in paraffin-embedded specimens collected from 78 gliomas and 12 benign brain lesion tissues by immunohistochemistry.Real time PCR was performed to detect CD147 mRNA expression.Results The positive rates of CD147,MMP-9 and TIMP-1 expression were 62%(48/78),71%(55/78),59%(46/78) respectively.We found a significant positive correlation between CD147,MMP-9,TIMP-1 expressions and poor gliomas differentiation by Spearman analysis(rs=0.2671-0.5631,Ps＜0.01).There was also a significant positive correlation between CD147 and MMP-9 expression(rs =0.3576,P＜0.01).In addition,the expressions of CD147(47% vs.80%,x2=9.510),MMP-9(56% vs.89%,x2=10.702),and TIMP-1(49% vs.71%,x2=4.138) were significantly higher in advanced gilomas than early gliomas(Ps＜0.05).The relative expression levels of CD147 mRNA in gliomas of Ⅰ to Ⅳ pathological grades were 0.15,0.27,0.46,0.78 respectively.Conclusion The expressions of CD147,MMP-9 and TIMP-1 were important characteristic of gliomas,which may serve as biomarkers in the glioma prognostic prediction.

This study was aimed to investigate the immunophenotypic characteristics of 109 cases of B-cell chronic lymphoid leukemia (B-CLL) so as to provide evidences for the diagnosis and therapy of B-CLL, and for the detection of the minimal residual disease and its prognosis. Immunophenotyping was performed in 109 patients of B-CLL by two/three color multiparameter flow cytometry analysis using a panel of monoclonal antibodies. The results showed that in 109 cases of B-CLL, all cases expressed CD19, the positive ratios of other B lineage antigen such as CD20, CD22 and CD23 were 95.40%, 94.50%, 86.20% respectively. None of the B-CLL cases expressed CD10. The expression ratio of FMC-7 and CD38 in 105 cases of B-CLL were 28.60% and 36.20%. Among the B-CLL cases the CD5(+) cells amounted to 86.23%, CD5(-) cells amounted to 13.76%, ZAP-70 protein was expressed in 12 out of 50 patients. It is concluded that immunophenotypic data are very useful for the diagnosis and detection of minimal residual disease of B-CLL, and the relationship between the immunophenotypic characteristics and the prognosis of B-CLL needs further study.

Objective To evaluate the clinical efficacy and safety of compound polymyxin B ointment combined with desonide cream for the treatment of subacute or chronic eczema. Methods A multicenter, randomized, double?blind, parallel?group, controlled clinical study was conducted. Totally, 144 patients with subacute eczema and 144 patients with chronic eczema were enrolled into this study, and both randomly and equally divided into the test group and control group. The test group and control group firstly topically applied compound polymyxin B ointment and its vehicle respectively, then both topically applied desonide cream 3 hours later. The drugs or vehicle were applied twice a day in all the patients. Patients′ symptoms and signs (including degree of itching, inflammation, erosion/exudation and infiltration/thickening, as well as area of target lesions) were evaluated, and the time to onset and duration of itching?alleviating effect were recorded. The clinical efficacy and safety of treatments were analyzed and compared between the test group and control group. Results The total symptom and sign scores significantly decreased to different extents on days 7 and 14 in the test group(subacute eczema patients:6.09 ± 2.78 and 3.68 ± 3.18 vs. 13.44 ± 1.66; chronic eczema patients: 6.56 ± 2.68 and 4.38 ± 3.27 vs. 12.96 ± 1.16)and control group(subacute eczema patients:8.26 ± 3.17 and 5.28 ± 4.05 vs. 13.60 ± 1.75;chronic eczema patients: 8.84 ± 2.90 and 6.25 ± 3.78 and vs. 12.64 ± 1.18)compared with those at baseline. Moreover, the total symptom and sign score of patients with subacute or chronic eczema was significantly lower in the test group than in the control group on days 7 and 14(all P<0.05). A significant increment was observed in the degree of decrease in scores for itch, infiltration/thickening in patients with subacute eczema in the test group compared with that in the control group(all P<0.01), as well as in scores for itch, infiltration/thickening and area of target lesions in patients with chronic eczema in the test group compared with those in the control group (all P < 0.05). In addition, patients with subacute eczema in the test group showed significantly shorter onset and longer duration of itching?alleviating effect than those in the control group(both P<0.05). The time to onset of itching?alleviating effect was also significantly shorter in patients with chronic eczema in the test group than in those in the control group(P<0.000 1), but there was no significant difference in the duration of it between the two groups of patients with chronic eczema. Clinicians and patients were both more satisfied with therapeutic effects in the test group than in the control group(all P<0.05). Conclusions Topical compound polymyxin B ointment can increase the efficacy of topical desonide cream for the treatment of subacute or chronic eczema, especially subacute eczema. Compound polymyxin B ointment also shows a favorable therapeutic effect on itching and infiltration/thickening in patients with eczema.

OBJECTIVETo evaluate the efficacy and safety of telbivudine use during the second and third trimester of pregnancy for reducing hepatitis B virus (HBV) transmission from highly viremic hepatitis B e antigen-positive (HBeAg+) mothers to their fetuses.

METHODSPregnant women, between weeks 20 to 32 of gestation, who were HBeAg+ and had HBV DNA more than 1.0*10(7) copies/mL were enrolled in our study. The women were offered inclusion into one of two treatment arms, based upon their personal preference: telbivudine or no telbivudine. The patients in the telbivudine treatment arm were administered 600 mg/d telbivudine at least until postpartum week 4. All delivered infants in both treatment arms were administered hepatitis B immune globulin (HBIG; 200 IU) within 12 hours of delivery and recombinant HBV vaccine (20 mug) at 0, 1 and 6 months. The HBV perinatal transmission rate was determined by measuring HBsAg and HBV DNA in infants at postpartum week 28.

RESULTSA total of 220 pregnant women were enrolled in our study, 120 chose the telbivudine arm and 100 chose the control arm. All telbivudine treated subjects were registered in the Antiretroviral Pregnancy Registry. Telbivudine treatment was associated with a marked reduction in the mothers' serum HBV DNA, HBeAg and ALT levels before delivery. A striking decline of HBV DNA levels in treated mothers was observed at week 2 of treatment, which was followed by a gradual and steady decrease that continued until delivery. Thirty-seven (31%) of the telbivudine-treated mothers and none (0%) of the untreated controls had polymerase chain reaction-undetectable viremia at delivery. At week 28, 0% of the infants delivered from telbivudine-treated mothers were HBsAg+ or HBV DNA+, as compared to 8% HBsAg+ or HBV DNA+ in the untreated control arm (P = 0.002). No telbivudine discontinuations occurred from adverse events, and no congenital deformities were observed in the infants delivered to telbivudine-treated mothers. Eighty mothers discontinued telbivudine at week 4 postpartum, and there were no cases of severe hepatitis. There were no significant differences between the two treatment arms for postpartum hemorrhage, adverse events during pregnancy, cesarean section, gestational age, or infants' height/weight or Apgar scores.

CONCLUSIONSTelbivudine use during the second and third trimester of pregnancy in HBeAg+ highly viremic mothers can safely reduce perinatal HBV transmission rates. Telbivudine was well-tolerated by our patient group. Furthermore, no safety concerns were observed in either the telbivudine-treated mothers or their delivered infants in short term follow-up.

OBJECTIVETo make multi-central clinical evaluation of the massage for supplementing qi and removing obstruction in the Governor Vessel for treatment of infantile diarrhea due to spleen deficiency.

METHODSBy using multi-central, randomized and controlled method, 275 cases were randomly divided into an observation group (n = 137) and a control group (n = 138). The observation group were treated by the massage for supplementing qi and removing obstruction in the Governor Vessel, and the control group by routine massage therapy in Tuina Science, a teaching material for college and school of TCM. After treatment for 7 days, their therapeutic effects were compared.

RESULTSThe cured rate was 83.2% in the observation group and 69.6% in the control group with a signifi cant difference between the two groups (P < 0.05), the former being better than the latter. The mean cured time was (3.22 +/- 1.04) days in the observation group and (4.20 +/- 1.11) days in the control group with a significant difference between the two groups (P < 0.05), the former being shorter than the latter.

CONCLUSIONThe massage for supplementing qi and removing obstruction in the Governor Vessel has a definite therapeutic effect on infantile diarrhea due to spleen deficiency, with rapid effect.

OBJECTIVETo investigate the association of the risk of prostate cancer (PCa) with the polymorphism of the CYP2E1 gene, smoking and drinking, and to explore the joint role of genes and living habits in PCa pathogenesis.

METHODSWe conducted a case-control study on 109 PCa patients and 202 age-matched non-PCa male controls, and detected the polymorphisms of CYP2E1 Rsa I and Pst I sites by PCR-RFLP using DNA from peripheral blood lymphocytes.

RESULTSThe history of deep smoking (OR = 2.29, 95% CI: 1.28 - 4.09) or heavy smoking (OR = 1.81, 95% CI: 1.02 - 3.22) was a risk factor. The CYP2E1 C1/C1 genotype significantly increased the risk of PCa (OR = 1.71, 95% CI: 1.04 - 2.82) and apparently interacted with drinking (OR = 2.21, 95% CI: 1.06 - 4.59). Heavy smokers with the C1/C1 genotype showed an increased risk of PCa (OR = 2.80, 95% CI: 1.20 - 6.56), as compared with non-smokers carrying the genotype of C1/C2 or C2/C2.

CONCLUSIONThe risk of PCa obviously increases in individuals with both the CYP2E1 C1/C1 genotype and the habit of smoking or drinking, and it has a significant positive correlation with the dose of tobacco exposure.

OBJECTIVETo observe the effectiveness of conscious sedation with midazolam, propofol and sufentanil for patients in plastic surgery.

METHODS81 patients, scheduled for plastic surgery, were randomly selected to receive conscious sedation with midazolam 0.05 mg x kg(-1) and sufentanil 0.1 microg x kg(-1) intravenously, following by a continuous infusion of midazolam-propofol-sufentanil combination (midazolam 5 mg + propofol 200 mg + sufentanil 10 microg, a total of 23 ml). The initial infusion rate was 0.2 ml x kg(-1) x h(-1), and was adjusted (in 20% of initial infusion rate increment) to maintain OAA/S score as 11 during the operation. The patients' vital signs, discomfort and level of sedation were evaluated at 5 to 10 min intervals until the end of the surgery. The complications (i. e. anoxemia, apnea, restlessness, nausea and vomiting), anesthesia duration and drug consumption were recorded. The drug infusion was discontinued at 5 - 10 min before the end of the surgical procedure. On the first postoperative day, patients were asked to rate their satisfaction with the anesthetic management and whether they would choose to receive the same anesthetic technique if necessary in the future.

RESULTSThe OAA/S score decreased from 20.0 +/- 0 to 11.9 +/- 2.6 after midazolam and sufentanil IV (P < 0.05), and was maintained as 10.5-11.1 during the procedure. At the end of the procedure, the OAA/S score returned to 16.0 +/- 2.2, which was also lower significantly compared with baseline value (P < 0.05). The induction of sedation produced a significant decrease in SBP and DBP (P < 0.05) and no significant changes in heart rate (P > 0.05). At the end of the procedure, SBP, DBP and HR returned to the baseline value. The anoxemia happened in 11 cases, apnea in 5 cases and restlessness in 2. No nausea and vomiting occurred. The anesthesia duration and consumption of midazolam, propofol and sufentanil were (101.1 +/- 42.5) min, (8.4 +/- 3.7) mg, (189.1 +/- 88.7) mg and (18.2 +/- 5.6) microg respectively. In an interview on the first postoperative day, 96% (78/ 81) of the patients were satisfied with their anesthesia and were willing to receive the same anesthetic technique if necessary in the future.

CONCLUSIONConscious sedation with midazolam, propofol and sufentanil is an effective anesthetic technique for patients in plastic surgery.

BACKGROUND: Investigation on epidemiologic features of knee osteoarthritis in many areas of China has been much reported. However, multicenter studies with large samples have been rarely reported. The published papers cannot give a good description about the epidemiologic features of knee osteoarthritis. OBJECTIVE: To evaluate the epidemiologic features of knee osteoarthritis in the patients aged over 40 years in China. METHODS: Meta-analysis was used to evaluate the data extracted from papers published 2001-2016 on the epidemiology of knee osteoarthritis in the middle-aged and elderly in China. The prevalence rate of knee osteoarthritis in the patients over 40 years of age was summarized, with every 10 years as group, and then analyzed on Stata 12.0 software. RESULTS AND CONCLUSION: Twenty-six articles were included, involving 42 199 people aged more than 40 years old. The total prevalence rate of knee osteoarthritis at the age above 40 years old in China was 17.0% (95% CI:16.7%-17.4%),the prevalence rate was 12.3% in male and 22.2% in female(P<0.05).Noticeably,the prevalence rate increased with age.The total prevalence rate in northern China was 16.1%(95% CI:15.6%-16.6%),12.2% in male and 21.4% in female;the total prevalence in southern China was 18.0%(95%CI:17.5%-18.5%), 12.3% in male and 23.1% in female. There was no significant difference in the prevalence rate between northern and southern China(P>0.05).The total prevalence rate in rural China was 23.6%(95%CI:16.7%-30.4%),with 15.4% in male and 28.1% in female;and the total prevalence in urban China was 20.0%(95% CI:16.2%-23.9%),with 13.7% in male and 24.3% in female. There was no significant difference in the prevalence rate between rural and urban China (P > 0.05). These results suggest that knee osteoarthritis in China is a common disease, characterized by increased prevalence with age, relatively significant difference between male and female, but no difference between northern and southern China as well as between rural and urban China. It is of great significance to timely propagate and perform interventional strategies for prevention and treatment of knee osteoarthritis in China.
