This study was conducted to investigate the physicochemical properties of Polyporus umbellatus sclerotial exudate. Morphological characteristics of the sclerotia and its exudate were observed during different stages of sclerotial formation. The pH of the exudate was detected at different time during cultivation. A phenol-sulfuric acid method was employed to determine the polysaccharide content of P. umbellatus sclerotial exudate during cultivating time. Additionally, the protein content was measured by means of BCA protein assay. Furthermore, CAT content was detected using ultraviolet absorption method. That the protein content of the exudate and CAT specific activity rose gradually during the passage of the cultivating time indicated a high level of oxidative stress during P. umbellatus sclerotial exudate formation. The results showed that the pH of the exudate increased gradually and then dropped down during sclerotial formation. That the pH of the exudate maintained the acidity state during the cultivation indirectly indicated that acidic environment would help sclerotial formation. The exudate produced gradually and was absorbed by the sclerotia itself.

By direct communication between clinicians and laboratorians, obstacles between clinical work and laboratory diagnosis were unequivocally found at an academic conference. Many clinical physicians feel disappointed and frustrated at the laboratory diagnosis by semen analysis and frankly express their expectations, as to recognize the role and significance of laboratory diagnosis, understand the value of routine semen analysis, work out the puzzles in the analysis of sperm morphology, fulfil the requirements for the identification of cells in semen, and obtain responses from and initiate discussions among laboratorians about the relevant questions. Both laboratorians and clinicians are appealing for strengthened management and earlier establishment of national standards and operating specifications for laboratory diagnosis by semen analysis.

Hoxa gene plays an essential role in the generation and development of the human female reproductive system. This gene is expressed in the Mullerian duct and the adult female reproductive system. Expression of Hoxa10 dramatically increased during the midsecretory phase of the menstrual cycle, corresponding to the time of implantation. Female mice lacking Hoxa10 have a uterine factor defect that results in death of the preimplantation embryo and failure of implantation. These results suggest Hoxa10 may have an important function in implantation. Hoxa10 - deficient males exhibit cryptorchidism that lead to male infertility.

Objective To study the expression of HOXA10 gene in the endometrium of normal fertile women and patients with unexplained infertility during different phases of menstrual cycle. Methods Endometrium samples were obtained by curettage in 52 normal fertile women and 38 patients with unexplained infertility during different phases of menstrual cycle, HOXA10 mRNA expression were detected by in situ hybridization and reverse polymerase chain reaction (RT-PCR). Results (1) HOXA10 mRNA were detected in the glandular and stromal cells of endometrium of fertile women during the menstrual cycle. By in situ hybridization (positive unite, PU), HOXA10 mRNA levels were significantly higher in the mid-secretory phase [glandular cells (G) 5.69?0.57,stromal cells (S) 7.48?0.67] and late-secretory phase(G 5.99?0.40,S 7.98?1.08) than those in late proliferative phase (G 3.35?0.20,S 3.20?0.37) and early secretory phase (G 3.07?0.26,S 3.18?0.27)(P

Objective·To investigate the incidence, risk factors and treatment of the catheter-related thrombosis (CRT) in breast cancer patients after implantation of totally implantable venous access port (TIVAP) in chemotherapy. Methods·A total of 190 cases after implantation of TIVAP were investigated. Color Doppler ultrasound was used to monitor the neck blood vessels to find whether there was CRT before chemotherapy and before taking out the port. The incidence of CRT, occurrence time, risk factors and treatment efficacy were observed. Results·There were 112 (58.9%) cases with CRT and 108 (56.8%) patients with asymptomatic thrombosis, and only 4 cases had symptomatic thrombosis, the incidence of which was 2.1%. Most thrombosis developed on the 21th day after catheterization, and the patients over the age of 60, with clinical stage Ⅲ - Ⅳ and chemotherapy regimens TEC (docetaxel combined pirubicin and cyclophosphamide) were the risk factors for thrombosis. All the patients with asymptomatic thrombosis accepted anticoagulant treatment with low molecular heparin, earthworms enzyme or aspirin, respectively, but there was no significant difference in efficacy in the three groups (P=0.743). Conclusion·Port catheter related symptomatic thrombosis incidence is low but the incidence of symptomatic thrombosis is high in the breast cancer patients after chemotherapy. Age, tumor stage and TEC chemotherapy regimens are the risk factors for catheter-related thrombosis.

Objective To investigate the nursing care in ultra-high pressure balloon dilatation for treating in patients with hemodialysis patients.Methods The patients with arteriovenous fistula were treated with ultra-high pressure balloon dilatation.Under fluoroscopy guidance the ultra high pressure balloon was used to dilate the stenosis.Preoperative preparation included psychological and routine care.Results Blood flow in all the 14 patients with hemodialysis was ≥ 250 ml/min,mean (270.00±27.33) ml / min.All patients were successfully completed the treatment,there were no angiorrhexis,bleeding,infection and embolism.Conclusion Careful nursing can promote the rehabilitation of patients,improve the effect of postoperative treatment.

Objective:To detect the expression of IDO, iNOS, gp91 NADPH ox releated with IFN-? function following Chlamydia trachomatis lung infection in mice and to investigate the immunological defense mechanism of IFN-?. Methods:A murine model of pneumonia induced by intranasal inoculation of Chlamydia trachomatis,mouse pneumonitis (MoPn) biovar,was used for this study. Chlamydial growth in the lung was assessed by inoculating HeLa 229 cell monolayer with lung homogenates followed by HRP conjugate anti-Chlamydial LPS mAb.The mRNA expressions of IDO, iNOS, gp91 NADPH ox and IFN-? in the lung were determined by RT-PCR on day 7 and 14 postinfection.Results:Chlamydial growth in the lung was observed on day 2 postinfection, peaking at day 7 with subsequent decline in quantity. At day 21 following inoculation, the IFU declined to the baseline. Contrast with the uninfected group, Th1-like cytokine IFN-? underwent a significant increase at day 7 and a decrease on day 14 postinfection. mRNA expression for IDO, iNOS, gp91 NADPH ox was significantly increased in the lungs on day 7 and 14 postinfection, IDO and gp91 mRNA expression was significantly highler at day 7(P

Objective To investigate the status and requirement of knowledge of reproduction and acquired immunodeficiency syndrome (AIDS)/sexually transmited disease (STD) in pregnant adolescents with abortion in order to conduct proper interventions. Methods Two hundred and ninety-one unmarried pregnant adolescents below 22 years old with abortion completed questionnaires which involved the information on individual social-demographics characteristics, knowledge of reproduction, AIDS/STD and sex-related beliefs, attitudes and partners. Results Among these 291 adolescents, 37.7% experienced first sexual intercourse before 19 years old, 69.1% performed well in the knowledge of reproduction, and 62.6% and 43.5% did well in the knowledge of AIDS and the knowledge of the other STD, respectively. The rate of implementation of contraception was far less than that of awarenesss of contraception(P<0.05). These pregnant adolescents were not enthusiastic for seeking reproductive knowledge, and 45.0% would like to acquire the knowledge from professionals. Conclusion The knowledge of reproduction and AIDS/STD in the pregnant adolescents is not adequate, and they fail to carry out the proper behaviors of contraception. More education should be conducted on AIDS/STD prevention and contraception among pregnant adolescents.

AIM: To analyze the change of serum inflammatory factors in glaucoma patients at different stages and its clinical significance. ·METHODS:Totally 70 cases of 128 eyes with primary open-angle glaucoma in our hospital from January 2014 to August 2016 were selected. According to the mean defect of visual field, they were divided into light ( observation Group 1 ) , moderate ( observation Group 2 ) and heavy group(observation Group 3). Another 65 cases of 130 eyes with cataract were taken as the control group in our hospital. The observation and expression of serum cytokines in these patients with glaucoma were taken. ·RESULTS:There was no significant difference in serum IL-2 and IFN- γlevels between the two groups (P>0. 05). The sIL-2R and IL-4 levels in the glaucoma group were higher than those in the control group, and the levels of IL-6 and IL-12 were lower than those of the control group (P<0. 05). The IOP and proportion of myopia in the glaucoma group was higher than that in the control group, the difference was not statistically significant ( P<0. 05) . The ratio of moderate myopia to severe myopia in each group was not statistically significant (P>0. 05). To observe the low myopia ratio in Group 3 of patients, it was less than observation Group 1 and observation Group2 ( P > 0. 05 ). There was no statistically significant difference between observation Group 1 and 2 of patients on IL-2, sIL-2R, IL-4, IL-6 and IFN-γlevels (P>0. 05). The level of sIL-2R in the Group 3 was higher than that in the Group 1, and the level of IL-12 was lower than that in the Group 1 and in the Group 2 (P<0. 05). There was no significant difference in IL-2, IL-4, IL-6 and IFN-γlevels between the glaucoma patients (P>0. 05). The IOP level and the proportion of myopia in the Group 3 were higher than those in the Group 1 and the Group 2 were observed, the difference was statistically significant (P<0. 05). The intraocular pressure was higher in Group 2 than in group 1 (P<0. 05). There was no statistically significant difference on proportion of myopia between observation Group 1 and observation Group 2 (P>0. 05). ·CONCLUSION: The levels of serum IL-12, sIL-2R and intraocular pressure in patients with primary open-angle glaucoma fluctuated significantly at different stages of the nerve injury, indicating that the immune response and intraocular pressure were involved in the process of optic nerve damage.
