Objective To investigate the age distribution and types of human papillomavirus (HPV) cervical infection in patients in Wuhan region, so as to provide scientific basis for the prevention and treatment of HPV infection and cervical cancer.Methods 9 915 exfoliated cervical cell specimens from patients in Wuhan Medical and Health Center for Women and Children between January 2015 and March 2016 were performed HPV genotyping (21 subtypes), clinical data of 1 732 HPV positive cases were statistically analyzed.Results HPV-positive rates in ≤25, 26~, 36~, 46~, and ≥56 age groups were 22.15%, 15.90%, 17.04%, 19.97%, and 17.57%,respectively (χ2=36.587,P<0.01),HPV-positive rates in ≤25 and 46~ age groups were both higher than other age groups.There were significant differences in single infection and multiple infection rates among different age groups respectively(χ2=14.39, 36.51,respectively, both P<0.05),single infection rate was highest in 46~ and ≤25 age groups (15.41% and 15.24% respectively);multiple infection rates was highest in ≤25 and ≥56 age groups (6.90% and 5.86% respectively).The percentage of single infection and multiple infection were 75.58% and 24.42% respectively, the major single infection type was HPV high-risk subtype (84.34%),the major multiple infection types were high-risk and high-risk compound subtype as well as high-risk and low-risk compound subtype, accounting for 60.52% and 38.77% respectively.The main single infection types were HPV high-risk subtypes 33, 68, 31 and 16, as well as and low-risk subtype 11, the ratios of single infection to multiple infection were 3.13, 2.03, 1.71, 1.67 and 2.00 respectively.Conclusion Cervical infection rates in women in Wuhan region is high in ≤25 and 46~ age groups, there are differences in the distribution of different HPV subtypes of single infection and multiple infection.

Objective To evaluate engraftment status of patients after allogeneic hematopoietic stem cell transplantation(Allo-HSCT) and prompt relapse of disease based on DNA polymorphism analysis technique.Methods Sixty-six cases were detected by DNA polymorphism analysis technique and 25 cases were monitored and analyzed dynamically during this period.Results After Allo-HSCT,48 patients obtained type of donors,but 13 patients did not; 5 patients showed mixed chimerism.Two cases of type of donors converted into mixed chimerism and 4 cases of mixed chimerism converted into type of donors after some time. The others' engraftment status did not change.Conclusion DNA polymorphism analysis technique can detect engraftment status of patients exactly, rapidly, which provides effective evidences of constitution for more clinical therapy projects.

Objective To investigate the effect of insulin-like growth factor-1 (IGF-1) on intercellular adhesion molecule-1 (ICAM-1) expression in rat model with congestive heart failure (CHF). Methods The model of CHF in male Sprague-Dawley rat was established using subcutaneous injection of isoproterenol. The rats were randomized into model group (n = 10),angiotensin converting enzyme inhibitors (ACEI) group ( n=10) and IGF- 1 group ( n = 10). The rats injected with saline were used as normal controls (n=10). The haemodynamic parameters of rats in each group were detected. The concentration of plasma angiotensin Ⅱ (Ang Ⅱ ) and expression of ICAM-1 in rat myocardium were determined by radioimmunoassay and immunohistochemistry,respectively. Results Compared with model group, ACEI and IGF-1 could rescue the diversities of hemodynamic parameters. In addition, ACEI and IGF-1 could also significantly down-regulated concentration of plasma Ang Ⅱ and inhibited ICAM-1 expression. Compared with ACEI, IGF-1 more significantly inhibited ICAM-I expression (0. 804 ± 0. 024 vs. 1. 254 ± 0. 059) and down-regulated concentration of plasma AngⅡ [(369.2±65.0) μg/L vs. (384.4±56.2) μg/L]. Conclusions IGF-1 can suppress ICAM-1 expression in rat model with CHF induced by isoproterenol. This effect may be related to inhibiting activation of RAS system.

To learn about the economic studies on traditional Chinese medicines in domestic literatures, in order to analyze the current economic assessment of traditional Chinese medicines and explore the existing problems. Efforts were made to search CNKI, VIP, Wanfang database and CBM by computer and include all literatures about economic assessment of traditional Chinese medicines published on professional domestic journals in the systematic assessment and quality evaluation. Finally, 50 articles were included in the study, and the systematic assessment and quality evaluation were made for them in terms of titles, year, authors' identity, expense source, disease type, study perspective, study design type, study target, study target source, time limit, cost calculation, effect indicator, analytical technique and sensitivity analysis. The finally quality score was 0.74, which is very low. The results of the study showed insufficient studies on economics of traditional Chinese medicines, short study duration and simple evaluation methods, which will be solved through unremitting efforts in the future.

OBJECTIVETo study the effect of nano-SiO2 on spatial learning and memory.

METHODSTwenty-four male rats were randomly divided into 3 groups: control group (C group), low dose group (L group) and high dose group (H group). The rats were intragastrically administrated with nanometer particles at 25 and 100 mg/kg body weight every day for 4 weeks. After exposure, the ability of learning and memory of rats was tested by Morris water maze, and electrophysiological brain stereotactic method was used to test long-tear potentiation (LTP) in dentate gyrus (DG) of the rats.

RESULTSThe increase rate of body weight in H group was reduced significantly compared with C group ( P < 0.05). In the space exploration experiment of Morris water maze test, the escape latency of H group was longer than that of C group (P < 0.05). The rats of H group spent less time in finding the target quadrant (P < 0.05) . The rate of LP induction of H group was significantly lower than that of C group (P < 0.05). After high fre quency stimulation (HFS), The changes of amplitude of population spike (PS) of L group and H group were lower than those of C group significantly (P < 0.05, P < 0.01).

CONCLUSIONNano-SiO₂may result in impairment of spatial learning and memory ability by reducing the rate of LTP induction and the increase of PS in hippocampus.

OBJECTIVETo investigate the effect of Sijunzi decoction (SJZD) on malondialdehyde (MDA) content and telomerase activity in heart, liver and brain tissues of D-galactose (D-gal) induced aging model mice.

METHODSD-gal aging mice model was established by cervicodorsal region subcutaneous injection with 10% D-gal once a day for six successive months. The model mice in the low-, middle- and high-dose SJZD treated groups were treated with SJZD in a dose of 6 g/kg, 12 g/kg, 24 g/kg per day respectively in the volume of 0.2 ml/10 g for 6 successive weeks. While the mice in the normal control group (NCG, non-modeled) and the model control group (MCG, modeled but untreated) were treated with distilled water instead. The MDA content and telomerase activity in heart, liver and brain tissues of mice was measured with TBA colorimetric method and PCR-ELISA respectively.

RESULTSIn MCG, the MDA content in heart, liver and brain tissues was significantly higher (P < 0.01), and the telomerase activity in liver and heart tissues was significantly lower (P < 0.01) but that in brain tissue was insignificant different to that in NCG (P > 0.05) respectively. As compared with MCG, the MDA content was significantly lower in the three SJZD treated group (P < 0.01). In comparison of telomerase activity between MCG and SJZD treated groups, it was shown that in heart tissue, there was an increased trend of the activity in the low-dose and middle-dose group, but with statistical insignificance (P > 0.05), but it did show a significant increase in the high-dose group (P < 0.05); in liver tissue no significant difference was shown between the three SJZD treated groups and MCG (P > 0.05); as for that in brain tissue, significant increase only shown in the high-dose group (P < 0.01).

CONCLUSIONSJZD can antagonize free radical injury, decrease the MDA content of heart, liver and brain in D-gal aging mice, and increase the telomerase activity in heart and brain tissues but with no effect on that in liver tissue.
