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.

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

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.

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 evaluate the early and midterm effect by retrospective analysis of the cone reconstruction in Ebstein′s anomaly. Methods From January 2012 through June 2016,16 patients with Ebstein′s anomaly underwent the cone reconstruction in our hospital. There were 7 males and 9 females at mean age(28.21 ± 11.88)years,including 12 patients of Carpentier B type,4 patients of Carpentier C type. There were 9 patients in New York Heart Association(NYHA)functional class Ⅲ,5 patients in NYHA functional class Ⅳand the others in NYHA functional class Ⅱ. All patients had Tricuspid insufficiency ,including 2 patients with Grade 2 ,10 patients with Grade 3 and 4 patients with Grade 4. All patients were followed up over a period of 6 to 51 months (mean:24.36 ± 10.71). By comparing the details of pre-operation with post-operation and post-operation with current stage,we analyze the outcomes of early and midterm effects. Results All patients are well survived. There were one patient recovering from the low cardiac output syndrome with adding the strength of the positive inotropic drug in the first day after operation ,and one patient recovering from bigeminy of ventricular prematurebeat with the aid of amiodarone and lidocaine the third day after operation. The remaining patients recovered smoothly. Early post-operative echocardiograms showed good right ventricular morphology and reduction in tricuspid regurgitation grade from(3.13 ± 0.62)to(1.75 ± 0.45)(P<0.001)with the functional class improved from(3.19 ± 0.66)to(2.00 ± 0.52)(P<0.001). After mean follow-up of(24.36 ± 10.71)months,the situation is improving furtherly with the tricuspid regurgitation grade reducing to(1.31 ± 0.48)(P=0.016)and the functional class rising to(1.50 ± 0.52) (P = 0.031). Conclusions This surgical technique for Ebstein′s anomaly can improve the function of tricuspid valve and the right ventricular morphology. It showed a satisfactory performance in the early and midterm results by enhancing the Cardiac function and life quality. But indications should be strictly grasped and more experiences need to be accumulated. Long-term effect need to be furtherly explored.

Purpose To investigate the expression of TET2 and DNMT3A in patients with peripheral T cell lymphoma (PTCL) and the relationship to immunophenotypes of PTCL.Methods Using a panel of immunohistochemical markers (CD3,CD4,CD10,BCL-6,CXCL-13,CD30,ALK),all cases of PTCLs were further divided into four groups,including angioimmunoblastic T cell lymphoma (AITL),peripheral T cell lymphoma,not otherwise specified (PTCL-NOS),anaplastic lymphoma kinase negative anaplastic large cell lymphoma (ALK-ALCL) and anaplastic lymphoma kinase positive anaplastic large cell lymphoma (ALK + ALCL).The expression of TET2 and DNMT3A in 89 cases of PTCL was detected by immunohistochemical analysis.Results 89 cases were divide into four subtypes,AITL (36/89),PTCL-NOS (26/89),ALKALCL (18/89),and ALK + ALCL (9/89).Immunohistochemistry staining revealed higher cytoplasmic expression of TET2 and DNMT3A in AITL than that of in PTCL-NOS and ALCL (P ＜ 0.05).And the nuclear expression of DNMT3A in patients with AITL was higher than that of PTCL-NOS and ALCL (P ＜ 0.05).The cytoplasmic expression of TET2 was positively related with both cytoplasmic and nuclear expression of DNMT3A in patients with AITL (P ＜ 0.05).Conclusion TET2 combined with DNMT3A could be used as markers in AITL diagnosis,which could provide new strategy for AITL diagnosis.
