Objective To investigate the clinical results in the treatment of developmental dysplasia of the hip (DDH) with one stage open reduction and Salter or Dega osteotomy for “walking age”children .Methods We retrospectively reviewed 16 patients(16 hips)with unilateral hip dislocation who had undergone one‐stage open reduction and Salter or Dega innominate osteotomy in the the“walking age”children .the results were evaluated clinically by McKay′s classification and radiologically by the modified Severin′s classification .Early signs of osteonecrosis were identified by neck widening ,epiphysis fragmentation ,and presence of a metaphyseal growth disturbance line in the first year after the operation .Results After a follow‐up of one year on average ,good clinical and ra‐diographic results were noted in 87 .5% and 81 .25% of the patients ,respectively .Osteonecrosis occurred in 3 hips(18 .75% ) .Con‐clusion One‐stage open reduction and Salter or Dega osteotomy is an effective treatment for developmental dysplasia of the hip in walking age .

Evidence has indicated that low doses of anti-tumor regimens can induce cell apoptosis in vitro, although different regimens induce apoptosis by different mechanism and pathway. In recent years, new tumor treatment strategy has been mainly focused on inducing tumor cell apoptosis. The present review discusses the advantages and disadvantages of inducing tumor cell apoptosis. The benefit of inducing apoptosis is not to cause inflammatory reaction, but as its disadvantage, it inhibits immune responses, and the phagocytosis of apopotic bodies may result in horizontal transfer of genes (including oncogenes and other oncogenic materials), which can be one of the causes of tumor relapse. This paper proposes that the tumor treatment strategy should be turn into promoting tumor cell necrosis and inducing anti-tumor immune responses.

OBJECTIVETo identify the correlation of the volume of residual urine (VRU) with the severity of bladder outlet obstruction (BOO) and detrusor contractility in patients with benign prostatic hyperplasia (BPH).

METHODSA total of 152 patients with clinically diagnosed BPH underwent ultrasonography for measurement of the prostate volume and RVU, free uroflowmetry, and urodynamic examination for the severity of BOO and detrusor contractility. Using the software SPSS20. 0, we analyzed the correlation between the ultrasonographic results and urodynamic parameters and compared the two sample means by the t-test.

RESULTSThe prostate volume was correlated positively with BOO severity (r = 0.432, P < 0.01) and detrusor contractility (r = 0.343 , P < 0.01) while Qmax negatively with BOO severity (r = 0.327, P < 0.01) but not significantly with detrusor contractility (r = 0.123, P > 0.05). VRU showed a significantly negative correlation with detrusor contractility when > 150 ml (r = -0.490, P < 0.01), even more significantly when > 300 ml (r = -0.717, P < 0.01), but exhibited no significant correlation with it when ≤ 150 ml (r = 0.041, P > 0.05).

CONCLUSIONVRU can somehow predict the detrusor function. For patients with VRU > 150 ml, especially for those with VRU > 300 ml, the detrusor function should be evaluated and urodynamic examination is recommended for exact assessment of BOO severity and detrusor contractility.

Conclusion Effective psychology intervention and family rehabilitation guides could impove psychological status and enhance quality of life of patients.

Relapse, which puzzled several generations of hematologists, is the bottle-neck of radical treatment for leukemias. The progress of Human Microbiome Project at the beginning of 21st century suggested that human body was a super-organism constituted by the core of human cells and symbiotic microorganisms. The elucidation and characterization of endogenous retrovirus and prion protein suggested the possible effects of co-evolutional microorganisms on human health. Recently, the elucidation of the roles of tunneling nanotubes in intercellular communication and transportation suggested a novel way for cellular communication and transport of oncogenic materials. The role and significance of in vivo cell fusion have been studied in more detail. On the other hand, donor cell leukemia was reported. All of these approaches provide novel insights for studying the mechanism of leukemia relapse. Based on previous work, the authors suggest the hypothesis: there are two possible mechanisms for the relapse of leukemias: the minimal residual disease (MRD) and intercellular transportation of oncogenic materials.

Objective To investigate the correlation between the Yes-associated protein (YAP) expression and epithelial-mesenchymal transition (EMT) by transiently transfecting with YAP small-interfering RNA (siRNA) in MHCC97H and MHCC97L cells.Methods MHCC97H and MHCC97L cells were transiently transfected by YAP siRNA.Furthermore,protein expressions and mRNA levels of characteristic markers of EMT (E-cadherin,N-cadherin) were examined by Western blotting and real-time polymerase chain reaction.Transwell invasion assay was used to detect changes of invasiveness of MHCC97H and MHCC97L cells.Results The YAP siRNA transfected group in MHCC97H was examined after 72 hours by Western blotting.The result showed obviously higher expression of E-cadherin in transfected group compared with the control group (P ＜ 0.05),and lower expression of N-cadherin (P ＜ 0.05).In MHCC97L cells,the expression of E-cadherin was also significantly increased (P ＜ 0.05),however,N-cadherin expression did not significantly change (P ＞ 0.05).Moreover,compared with the control group,transwell invasion assay showed that the number of the transfected group cells significantly decreased in MHCC97H(66 ± 6.89 vs 117 ± 7.23,P ＜ 0.05),and compared with the control group,the number of the transfected group also significantly decreased in MHCC97L (40 ±2.65 vs 77 ±4.33,P ＜0.05).The result of real-time polymerase chain reaction indicated that mRNA levels of E-cadherin increased (P ＜ 0.05),but mRNA levels of N-cadherin did not significantly change (P ＞ 0.05).This is considered as post-transcriptional regulation after silencing YAP in MHCC97H and MHCC97L.Conclusions YAP silencing is able to inhibit EMT in MHCC97H and MHCC97L cells by modulating the characteristic markers of EMT.The inhibition of YAP expression can reduce the invasion ability of hepatocellular carcinoma cells.

Objective Few researches are reported on the association of integrinαvβ6 with vaginal mucous infection and de-fense.This study aimed to investigate the effects of IL-6, TGF-β, and IFN-γon the expression of integrinαvβ6 in the vaginal epithelial cell line VK2/E6E7. Methods Immortalized human vaginal epi-thelial cells (VK2/E6E7) were cultured in vitro and treated with gra-dient concentrations of IL-6 (1, 10, 50, and 100 ng/mL), TGF-β(0.1, 1, 10, and 100 ng/mL), and IFN-γ(50, 500, 2500, and 5000 U/L) , respectively.After 48 hours, the cells were collected and total RNA extracted by the Trizol method to be reversely tran-scribed to cDNA. The expressions of integrin αand β6 subunit mRNA were detected by real-time quantitative PCR. Results In the IL-6-treated VK2/E6E7 cells, the integrin αand β6 subunit mRNA expressions were significantly lower in the 1 ng/mL and 10 ng/mL groups but remarkably higher in the 100 ng/mL group (1.14 ±0.12 and 1.37 ±0.25) than in the blank control (1.00 ±0.09) (P<0.05), and only the expression ofβ6 subunit mRNA was elevated in the 50 ng/mL group (P<0.05), with the expressions increased in a concentration-dependent manner.In the TGF-βtreated VK2/E6E7 cells, the expressions of integrinαandβ6 subunit mRNA were significantly lower in the 0.1 ng/mL and 1 ng/mL groups but remarkably higher in the 100 ng/mL group than in the blank control (1.00 ±0.09) (P<0.01), and only the expression ofβ6 subunit mRNA was elevated in the 10 ng/mL group (4.31 ±0.78, P<0.01), with the expressions increased in a concentration-dependent manner.In the IFN-γtreated VK2/E6E7 cells, the expressions of both integrinαandβ6 subunit mRNA were significantly lower in the 50 U/L, 500 U/L, 2500 U/L, and 5000 U/L groups than in the blank control (all P<0.01). Conclusion IL-6 and TGF-βhave an inhibitory effect the expression ofαvβ6 in VK2/E6E7 cells at low concentrations, which gradually diminishes with the increased concentration of inflammatory factors.In the early stage of inflammation, IFN-γcan effectively suppress the expression ofαvβ6 at a high concentration.However, with the progression of inflammation and decrease of its concentration, IFN-γloses its inhibi-tory effect and therefore does not help inflammation control.

Up to date, eight types of human herpes viruses have been identified, all of which are ubiquitous, and usually establish latent infection in the host after primary infection. Since most of the herpes viruses are maintained in an asymptomatic form, they are often neglected. However, under some circumstances, these herpes viruses can cause fatal or severe diseases. Furthermore, the association of herpes viruses with hematopoietic malignancies is attracting researchers' attention. With the extensive development of hematopoietic stem cell and organ transplantation, reports regarding transplantation failure and complication caused by infection of human herpes virus has been increasing. Cytokine storm was firstly suggested as the mechanism of graft-versus-host diseases. In recent years, which has also been applied in the pathogenesis research of inflammation, and is supposed to play an important role in severe virus infection. In this paper, through discussing the possible role of latent infection of human herpes virus in the failure or complication of bone marrow or hematopoietic stem cell transplantation, and in refractory leukemia, the function and significance of latent infection of human herpes virus and the cytokine storm it caused were investigated.
