The purpose of this study was to investigate how Zuogui pills from the Kidney-tonifying and Nourishing Yin formula, in combination with the gonadotrophin-releasing hormone antagonist cetrorelix, affected the ovarian local oxidative stress response in decreasing ovarian reserve (DOR) mice. All animal experiments were carried out in accordance with the guidelines and standards established by Jinan University's Experimental Animal Management Committee. Cyclophosphamide (CTX)-treated DOR mice were given Zuogui pills, cetrorelix, or a combination of the two drugs intragastrically. After treatment, there were changes in the estrous cycle, serum sex hormone levels, oxidative stress-related indexes, growth biochemical factor levels, and SIRT1/P53/P21 expression. In comparison to the model group, the Zuogui pills and the cetrorelix+Zuogui pills group had significantly prolonged estrous periods and shortened interestrous periods, and the cetrorelix+Zuogui pills group had a significantly shortened cycle length. Follicle-stimulating hormone (FSH) decreased and estradiol (E₂) increased in all treatment groups compared to the model group, oxidative stress indexes nitric oxide synthase (NOS), nitric oxide (NO), and reactive oxygen species (ROS) decreased, growth biochemical factors brain derived neurotrophic factor (BDNF) and growth differentiation factor 9 (GDF-9) concentrations increased significantly, and leukemia inhibitory factor (LIF) showed no significant change. SIRT1/P53/P21 immunohistochemical results revealed that, when compared to the model group, the expression of SIRT1 increased while the expression of P53 and P21 proteins decreased in all treatment groups, with the cetrorelix+Zuogui pills group having the largest decrease, with significant differences in all indicators. We conclude that cetrorelix combined with Zuogui pills for kidney nourishing and Yin recipe improved the oxidative stress response in the follicle by regulating the SIRT1/P53/P21 pathway, reducing peroxide product production, protecting ovarian function, and regulating ovarian hormone secretion, and its efficacy is superior to that of cetrorelix or Zuogui pills alone.

OBJECTIVETo explore the neuro-protective effect and mechanism of qingkailing injection (QKL) against cerebral injury caused by E. coli-meningitis (CM).

METHODSThe CM model rabbits were treated by ampicillin with QKL as adjuvant. The leukocyte count and protein content in cerebral spinal fluid (CSF), the contents of water, sodium, potassium and calcium in cerebral tissues were measured before, 16 h and 26 h after Bacillus coli injection respectively. The expression of matrix metalloproteinase-9 (MMP-9) was determined at the same time.

RESULTSAdjunctive treatment with QKL can not only inhibit the increase of leukocyte cells, protein content in CSF, and water, sodium, calcium content in cerebral tissues, but also the decrease of potassium content revealed during simple antibiotic treatment. It also can decrease the expression of MMP-9 in cerebral tissues of rabbits with CM.

CONCLUSIONAs an adjunctive treatment, QKL can prevent transient inflammatory reaction and aggravation of brain injury in CM induced by simple antibiotic treatment, its mechanisms might relate with calcium antagonism and attenuation of MMP-9 expression in brain tissues.

This study was aimed to investigate the effect of chemokine-like factor superfamily 8 (CKLFSF8) on proliferation and expression of epidermal growth factor receptor (EGFR) of HL-60 cells. Expression of CKLFSF8 mRNA on HL-60 cell line was assayed by RT-PCR; the target gene was transfected into the cells by lipid vector, cell proliferation was determined by MTT assay, while expression of EGFR in HL-60 was determined by immunocytochemical technique. The results indicated that expression of CKLFSF8 existed in HL-60 cells. After transfection, cell proliferation was inhibited (P < 0.05) and the expression of EGFR in HL-60 cells was also discovered to be inhibited (P < 0.05). It is concluded that the proliferation and expression of EGFR in HL-60 cells can be inhibited by transfection of CKLFSF8. The novel chemokine may provide a new approach in the treatment of leukemia.

OBJECTIVETo study the relationship between ultrasonic bone mineral density (BMD) of calcaneus and age, height, and body weight, and to establish the normal reference value for stiffness index (SI) of healthy subjects in Guangxi autonomous region and provide scientific foundation for the diagnosis and prevention of osteoporosis.

METHODSSI of calcaneus in 1 816 healthy adults aged 11-90 years (775 men, 1 041 women) were measured with quantitative ultrasound. According to their ages, all the men and women were divided into 13 groups by 5-year age group.

RESULTSSI reached peak values in 21-25 year group in men (range: 111.45 +/- 21.19) and in 16-20 year group in women (range: 101.26 +/- 17.51). Then the SI value began to decline with aging. The SI featured by a typical dual-peak curve in women and the decrease rate of SI was faster in women than in men over 61 years. Multivariate linear regression analysis showed significantly negative correlation between SI and age (P < 0.001), positive correlation between SI and body weight (P < 0.05 for men; P < 0.01 for women), and positive correlation between SI and height in women (P < 0.01).

CONCLUSIONSI correlates with age, height, and weight. The acquired SI value may provide a reference for the diagnosis of osteoporosis.

The aim of this study was to investigate whether exosomes derived from K562 cells and human monocyte-derived dendritic cells (DCs) transfected with total RNA of K562 cells are capable of inducing antigen-specific cytotoxic T lymphocytes (CTL) responses in vitro. DCs were generated from peripheral blood mononuclear cells (PBMNC) of healthy volunteers in the presence of GM-CSF and IL-4, and then were transfected with K562 RNA by using DOTAP lipofection. Exosomes was extracted from the supernatant of DCs and K562 cells. The T cell were activated to be tumor specific CTL after DCs and exosomes were co-cultured with autologous T cells derived from healthy volunteers' PBMNC. The effect of CTL on K562 cells was detected by MTT assay. The results showed that treatment of T cells with exosomes derived from K562 cells or DCs transfected with total RNA of K562 cells could significantly promote their killing ability on K562 cells as compared with untreated T cells (P < 0.05). The killing ability of T cells treated with exosomes on K562 cells was stronger than on HL-60 cells (P < 0.05). It is concluded that the specific CTL immune response to leukemia cells can be induced by exosomes derived from K562 cells.

OBJECTIVETo study the impact of maternal weight gain during pregnancy on the risk of infant obesity within 1 year old.

METHODSA total of 785 infants who were born in Hefei and participated children medical care in one district health center and their mothers were chosen as the research subjects from September 2010 to September 2011. Three groups were classified by weight gain during pregnancy according to the percentiles: excessive pregnancy weight gain group of 126 pairs, adequate pregnancy weight gain group of 542 pairs and inadequate pregnancy weight gain group of 117 pairs. Mother's general demographic information was collected. The height and weight were measured when the infant was 42 days, 3, 6, 9, and 12 months of physical examination. Z score was calculated. The differences of Z score in different groups were compared and the RR values of different weight gain during pregnancy on infant obesity were computed.

RESULTSThe weight-for-age Z score (WAZ) of infant at 42 days 3, 6, 9 and 12 months in excessive pregnancy weight gain group were 0.23 ± 0.93, 0.25 ± 1.03, 0.23 ± 0.99, 0.28 ± 1.09, 0.26 ± 1.14, respectively, all higher than that of the corresponding age in adequate pregnancy weight gain group (-0.04 ± 1.02, -0.07 ± 0.99, -0.05 ± 0.98, -0.06 ± 0.97, -0.07 ± 0.95, respectively). The differences were statistically significant (all P values < 0.05). In excessive pregnancy weight gain group, infant body mass index (BMI) at 9 months ((18.01 ± 0.15) kg/m(2)) and 12 months ((17.66 ± 0.15) kg/m(2)) were higher than that of adequate pregnancy weight gain group ((17.63 ± 0.13) and (17.22 ± 0.15) kg/m(2), respectively). The differences were statistically significant (all P values < 0.05). Differences of infant Height-for-age Z score (HAZ) among three groups were not statistically significant (all P values > 0.05). Compared to adequate pregnancy weight gain group, RR (95%CI) value of infant obesity in excessive pregnancy weight gain group was 1.86 (1.14 - 3.03).

CONCLUSIONExcessive maternal weight gain during pregnancy increased the risk of infant obesity within 1 year old.

Objective:To observe the effect of tuina exercise on simple obesity in college students.Methods:Fifty-seven college students with simple obesity were divided into two groups according to the stratified randomization method.Twenty-eight in the tuina exercise group were trained in tuina exercise;while 29 in the auricular acupoint sticking group were treated with acuricular acupoint sticking.The tuina exercise group was trained once every other day,and 10 times made one course.The auricular acupoint sticking was replaced once every 4 d,and 5 times made one course.After 2-course treatment,the total therapeutic effect,weight,body mass index (BMI),waist and hip circumferences,serum total cholesterol (TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were assessed.Results:The total therapeutic effect was 86.2％ in the auricular acupoint sticking group and 85.7％ in the tuina exercise group.There was no significant difference between the two groups (P＞0.05).After treatment,the weight,BMI,waist and hip circumferences were decreased and the differences were statistically significant (all P＜0.05).The waist and hip circumferences in the tuina exercise group were lower than those in the auricular acupoint sticking group,showing statistically significant differences (all P＜0.05).After treatment,there were no significant intra-group differences in TC,TG,HDL-C and LDL-C in the two groups (all P＞0.05),and the between-group differences were not significant (all P＞0.05).Conclusion:Tuina exercise has reliable effect in treating obesity.It can produce more significant improvements in waist and hip circumferences than auricular acupoint sticking.But no obvious effect is shown in blood lipid indicators.

Objective Radionuclide-labeled low molecular weight polypeptide is reeently advocated for the diagnosis and treatment of malignant tumor. The purpose of this study was to evaluate the anti-tumor effect of 131Ⅰ-Tyr-octreotide in nude mice bearing human non-small cell lung cancer (NSCLC). Methods 131Ⅰ-Tyr-octreotide was prepared by Ch-T method. The radiochemical purity was measured and biodistribution was evaluated. The nude mice models bearing human NSCLC were studied and divided into four groups: group A injected 131Ⅰ-Tyr-octreotide through tail vein, group B injected normal saline, group C injected 131Ⅰ-Tyroctreotide through stroma and group D injected 131Ⅰ through stroma. The radioactivity ratio of tumor to normal tissue (T/NT) was calculated over region of interest (ROI). The tumor cell cycle and cell apoptosis were analyzed by flow cytometry (FCM), terminal deoxynucleotidyl transferase mediated dUTP-biotion nick end labeling (TUNEL) and histopathological analysis. Statistical analysis was performed with SPSS 11.0, and the comparison for difference between groups performed with one-way ANOVA analysis. Results The labeled radiochemical purity was (95.23±1.67)% and specific activity of 3.5×106Bq/ug. The biodistributiou showed high uptake in kidney, and low uptake in liver and spleen. The radioactive uptake in group C was higher than the other groups, and the retention time was longer. The T/NT was 52.74±0.13 after 24 h, which was much higher than that the other groups (group D: 8.90±0.23, group A: 6.42±0.02, q=628.81 and 664.33, all P<0.05). The resuits of tmnor cell cycle determined by FCM showed that the G1 phase was blocked mast remarkably in group C than the other groups [group C: (83.17±6.86)%, group A: (57.02±18.81)%, group D: (49.29±7.80)%, group B: (45.88±5.13)%, q=5.29, 6.86, 7.55, 1.56, 2.26, 0.69, all P<0.05]. Apeptotic cells were observed by TUNEL, and apoptotic body was detected by immuno-histochemical examination. Conclusions 131Ⅰ-Tyr-octreotide was easily labeled by Ch-T. 131Ⅰ-Tyr-octreotide could induce tumor cell apoptosis and inhibit the tumor cell of NSCLC. It might be a potential target-directed agent in NSCLC.
