Objective: To investigate the expression of angiopoietin-related growth factor (AGF) in obese patients and its relationship with body mass index(BMI), waist circumference(WC), waist-hip ratio(WHR), blood glucose(FBG), plasma insulin(FINS) levels, and HOMA-insulin resistance index(HOMA-IR). Methods: Plasma AGF levels were assayed by ELISA in 40 patients with obesity and 40 normal controls. The relationship of AGF level with BMI, WC, WHR, HbA 1c, blood lipids, FBG, FINS, and HOMA-IR was also analyzed. Results: AGF levels in patients with obesity were significantly increased compared with that in the control group ([177.55±74.09] ng/ml vs [122.37±66.91] ng/ml, P<0.05). We also found that AGF level was positively correlated with Triglyceride(TG), FINS and HOMA-IR(r=0.325, P<0.05; r = 0.451, P<0.01; r = 0.483, P<0.01); and was negatively correlated with high-density lipoprotein cholesterol(HDL, r= -0.529, P<0.01). Multiple regression analysis showed that HDL, BMI and FINS were the factors influencing AGF levels. Binomial Logistic regression analysis indicated that AGF level was positively correlated with obesity after adjusting sex, age, total cholesterol (TC), TG, HDL and low-density lipoprotein cholesterol (LDL) (OR>1). Conclusion: The change of AGF level is associated with the metabolism disorder in obese patients, and it may also contribute to the pathogenesis of obesity.

Thrombin is the most important factor in hemostasis. In recent years, it has been found that thrombin is a potent mitogen capable of inducing cellular functions. Therefore, it is proved to be of importance in promoting the growth, metastasis and angiogenesis of cancer. Anticoagulant therapy not only reduce the characteristic hypercoagulability of cancer, but also inhibits growth and metastasis of cancer, and alters the fundamental biology of cancer. In this paper thrombin and its receptor, relationship of thrombin and its receptor with cancer growth, metastasis and angiogenesis, the mechanisms of thrombin influence on cancer angiogenesis, as well as application prospects on anti-angiogenesis and anti-coagulation therapy were reviewed.

OBJECTIVETo study the protective effect of Ligustrazine Injection (LI) against cisplatin-induced ototoxicity and to explore its mechanism.

METHODSThirty healthy adult guinea pigs were randomly divided into three groups, 10 in each group, i.e., the normal control group, the cisplatin group, and the LI group. Guinea pigs in the normal control group were intraperitoneally injected with normal saline at 3 mL/kg for 7 consecutive days. Those in the cisplatin group were intraperitoneally injected with cisplatin at 3 mg/kg for 7 consecutive days. Those in the LI group were intraperitoneally injected with LI at 140 mg/kg for 7 days, but cisplatin (3 mg/kg) was intraperitoneally injected from the opposite side starting from the 4th day. Brainstem auditory evoked potential (BAEP) was performed in all animals before and after injection. All animals were sacrificed after the final testing under anesthesia and their cochleas collected. Half the cochleas of each group were collected for silver nitrate staining of cochlear basilar membrane stretched. The other half the cochleas of each group made into paraffin sections to observe the apoptosis of cochlea cells by TUNEL method and the expression levels of c-Jun detected by immunohistochemistry.

RESULTSThere was no statistical difference in the difference of BAEP threshold among the 3 groups before injection (P > 0.05), but the BAEP threshold increased in the cisplatin group and the LI group (P < 0.05). Besides, it was higher in the cisplatin group (P < 0.05). In the cisplatin group, most hair cells were missing, spiral ganglion cells obviously decreased, more TUNEL positive cells occurred, and the expression of c-Jun was stronger. But the aforesaid impairment in the LI group was obviously lessened (P < 0.05).

CONCLUSIONSLI showed certain antagonist effect on cisplatin-induced ototoxicity. Its mechanism might be associated with scavenging oxygen radicals of the cochlea tissue, improving the microcirculation, and fighting against apoptosis.

OBJECTIVETo investigate the pathogenic infection and its drug resistance in expressed prostatic secretion (EPS) and its correlation with serum PSA, and provide some evidence for the systematic and normalized diagnosis and treatment of prostatitis.

METHODSThree EPS swabs were collected from each of the 320 prostatis patients following measurement of the serum PSA level, 1 for bacterial culture and identification, 1 for detection of Mycoplasma and drug sensitivity, and the other for examination of Chlamydia trachomatis antigen by colloidal gold immunoblot.

RESULTSTotally 244 strains were isolated from the 320 EPS samples, including 188 bacterial strains (dominated by Staphylococcus and sensitive to vancomycin or linezolid) and 44 Mycoplasma and Chlamydia strains (mainly Ureaplasma urealyticum and susceptible to josamycin or doxycycline). The serum PSA level was significantly higher in the pathogen-positive than in the pathogen-negative group ([6.98 +/- 0.56] microg/L vs [2.32 +/- 0.12] microg/L, P < 0.05).

CONCLUSIONProstatitis may lead to the elevation of the serum PSA level and the pathogens involved vary in their resistance to different antibacterial spectrums. Therefore, appropriate and individualized antibiotic therapy should be selected according to etiological diagnosis and the results of drug sensitivity test.

Objective To investigate the effects of family allergic history and dermatophagoides farina on the expressions of Th1/Th2 cytokine of cord blood and allergic disorders in infancy.Methods Ten mil cord blood were obtained from 34 neonates which 17 cases had family allergic history and 17 cases didn′t have.Cord blood mononuclear cells(CBMC) were isolated by gradient centrifugation with Ficoll and were cultured with phytohemagglutinin(PHA) or dermatophagoides farina for 48 hours in vitro.The expressions of interleukin(IL-4) and interferon(IFN-?) of the culture supernatant were detected by enzyme-linked immunosorbent assay(ELISA).Two groups were visited with telephone or clinical service every 1 or 2 months in 1 year follow-up survey.Results In no stimulation,the expressions of IL-4 of family allergic history and no family allergic history were(11.35?1.80) ng/L and(11.0?1.50) ng/L,respectively,there was no significant difference.The expressions of IFN-? were(9.55?1.47) ng/L and(10.19?1.37) ng/L,respectively,there was no significant difference also.In PHA stimulation,the expressions of IL-4 were(43.45?4.57) ng/L and(37.58?3.41) ng/L,respectively,there was significant difference.The expressions of IFN-? were(72.61?25.40) ng/L and(65.84?29.96) ng/L,respectively,there was no significant diffe-rence.In low density dermatophagoides farina stimulation,the expressions of IL-4 were(40.54?3.64) ng/L and(37.17?2.60) ng/L,respectively,which had significant difference.The expressions of IFN-? were(35.30?2.73) ng/L and(40.55?1.85) ng/L,respectively,which had significant difference.In high density dermatophagoides farina stimulation,the expressions of IL-4 were(43.50?3.19) ng/L and(39.55?4.13) ng/L,respectively,which had significant difference.The expressions of IFN-? were(39.40 ?5.21) ng/L and(40.94?2.96) ng/L respectively,which had no significant difference.Allergic diseases were happened in 7 cases of 13 cases with family allergic history and in 2 cases of 15 cases without family allergic history in 1 year follow-up except lost follow-up cases.There were significant difference in 2 groups.Conclusions Th2 cells of cord blood are relative dominant in neonates having family allergic history.Th2 cells relative dominant are more obvious in dermatophagoides farina stimulation.The neonates having family allergic history have a tendency to get allergic diseases in childhood.
