The pathogenesis of heart failure is a complex progression and associated with abnormal regulation of many signaling pathways. As a cofactor of hemoglobin, myoglobin, oxidative respiratory chain, DNA synthase and other important proteins, iron plays an indispensable role in myocardial energy metabolism. Recently, a large number of studies have shown that heart failure is related to the disorder of iron metabolism. Both iron deficiency and iron overload can lead to the development of a variety of cardiomyopathy, and even progress to heart failure. Iron metabolism could be a key target for the diagnosis, prevention and treatment of heart failure. Here, we review the basic process of iron metabolism and its mechanism in heart failure, expecting to provide new clues and evidence for the treatment of heart failure.

In this article we analyzed the current development of moxibustion treating rheumatoid arthritis from the usefulness, advancement, synergistic effect as well as the variance between different kind of moxibustion. We concluded that moxibustion was an effective intervention for treating RA, and the methods used in moxibustion were searched in clinic. But the clinical tralls has a long way to go, we should pay more attention to the critical issues while in the use of moxibustion.

Hepatitis B virus (HBV)-human DNA integration is a commonly seen event in the evolutionary process of hepatocellular carcinoma (HCC). HBV chronic infection induces HBV mutation, HBV integration and the inflammatory microenvironment alternation in the hosts, which provides a evolutionary soil for the hepatocarcinogenesis. The second generation sequencing technique provides a better approach for understanding the HBV integration mechanism in HCC. This review focuses on the features of HBV integration and influences of HBV integration on human, virus genomes, and discusses the association of HBV integration with HCC.

AlM: To demonstrate the effect of comprehensive treatments for meibomian gland dysfunctional dry eye.
METHODS:Totally, 86 cases (172 eyes) in our hospital, who suffered from meibomian gland dysfunctional dry eye, were measured by BUT, CFS, the machine of infrared meibomian gland function and testing meibomian gland after extrusion. The scores of meibomian gland function missing and secretions were observed, which as a diagnosis, and assessed the effectiveness of treatment, after took comprehensive treatments in different stages ( comprehensive treatments including cleaning, hot covering, massaging, TobraDex, Pranoprofen and Lubricant, etc. ) .
RESULTS:All patients were treated and observed for 3wk, in which 46 cases (92 eyes) of cured, 29 cases (58 eyes) effective, 11 cases (22 eyes) ineffective, the total effective rate was 87. 2%. After 6wk, 68 cases (136 eyes) of cured, 13 cases (26 eyes) effective, 5 cases (10 eyes) ineffective, the total effective rate was 94. 2%, not appeared adverse ocular and systemic reactions in the process of treatment.
CONCLUSlON: Taken comprehensive treatments for meibomian gland dysfunctional dry eye could effectively shorten the course of the disease, quickly remove meibomian gland tube obstruction, restore the meibomian gland secretion and stable the lipid layer, and could reduce the discomfort of patients with dry eye positively and effectively.

OBJECTIVETo observe the characteristics of sperm single-stranded DNA breaks (SSB) and double-stranded DNA breaks (DSB) in infertile men, explore the association of DSB with male infertility, and provide a new observation index and idea for the diagnosis and treatment of the disease.

METHODSThis study involved 60 infertile men (infertility group) and 30 normal healthy males with infertile wives (control group). We comparatively analyzed the seminal parameters of the two groups, determined sperm concentration and viability using the computer aided sperm analysis system, measured the sperm survival rate by hypoosmotic swelling (HOS) test, examined sperm morphology by Diff-Quick staining, and detected sperm DNA damage by two-tail comet assay.

RESULTSNine two-tail comet models were established for detecting sperm DNA integrity. Comparisons between the fertility and control groups showed that the sperm DNA fragmentation index (DFI) was (33.8 ± 13.1) vs (16.3 ± 7.9)% (P < 0.01), the SSB-DFI was (19.2 ± 11.4) vs (14.9 ± 7.6)% (P > 0.05), the SSB-DFI/DFI was (56.8 ± 32.4) vs (91.4 ± 27.8)% (P < 0.01), the DSB-DFI was (23.9 +13.4) vs (6.1 ± 2.7)% (P < 0.01), and the DSB-DFI/DFI was (70.8 ± 19.5) vs (37.4 ± 11.3)% (P < 0.01). The optimal cut-off value of DSB-DFI/DFI in the diagnosis of male infertility was 39.5%, with the AUG, sensitivity, and specificity of 0.969, 98.3%, and 90%; that of DSB-DFI was 15.85%, with the AUC, sensitivity, and specificity of 0.912, 86.7%, and 80%; and that of DFI was 18.65%; with the AUC, sensitivity, and specificity of 0.861, 90%, 70%, respectively. In the infertile men, neither SSB-DFI nor SSB-DFI/DFI exhibited any correlation with semen parameters (P > 0.05); DFI was correlated negatively with the percentage of progressively motile sperm, sperm survival rate, and the percentage of morphologically normal sperm (P < 0.05 or P < 0.01), but not correlated with sperm concentration (P > 0.05); both DSB-DFI and DSB-DFI/DFI showed a negative correlation with sperm concentration, sperm survival rate, and the percentages of progressively motile sperm and morphologically normal sperm (P < 0.05 or P < 0.01).

CONCLUSIONDouble-stranded, rather than single-stranded DNA breaks, may be a factor inducing male infertility. The type of sperm DNA strand damage is of much reference value for the assessment of male fertility.

AIM: To compare the safety and efficacy of conjunctival autograft transplant ( CAT ) and limbal - conjunctival autograft transplant (LCAT) for primary pterygium.
METHODS: In this prospective, randomized and controlled clinical study, 120 patients ( 120 eyes ) diagnosed with primary pterygium were collected in NO. 474 Hospital of Chinese PLA from January 2014 to January 2015. The 120 patients enrolled in the study in turn, and divided into two group by the odd and even number. The odd number underwent CAT and the even number underwent LCAT.
RESULTS:One hundred and seven patients (107 eyes) completed the follow-up of 1a, including 54 patients (54 eyes) from the CAT group and 53 patients (53 eyes) from the LCAT group. Four patients (4 eyes, recurrence rate 7. 4%) in the CAT group and 2 patients ( 2 eyes, recurrence rate 3. 8%) in the LCAT group developed recurrence. However, there were no significant in recurrence rate between CAT group and LCAT group (P =0. 678).
CONCLUSION: CAT and LCAT might be both effective treatment for primary pterygium for reducing the recurrence rate of pterygium. However, LCAT is the optimal surgical method for primary pterygium.

OBJECTIVEIn contrast to severe aplastic anemia (SAA), the appropriate management of patients with moderate aplastic anemia (MAA) is unclear. Recently, it was reported that when childhood MAA was treated with supportive care alone, 2/3 of patients progressed to SAA, and therefore patients with MAA should be treated with immunosuppressive (IS) therapy in time. The present study aimed to review the natural history, the rate of progression to SAA and outcome of children with MAA seen at our institution over the past 12 years and to explore the relationship between the effectiveness of IS therapy and the immune mediated pathological mechanism.

METHODSSeventy-one MAA patients were included in this study. At the first stage, thirty-six children with MAA were given IS therapy (IS group, antithymocyte globulin, ATG or cyclosporin-A, CSA). The therapeutic effects were evaluated and compared with those of 35 children with MAA who received the treatment of supportive care alone (androgens, control group). At the second stage, the patients with MAA progressed to SAA were given combined immunosuppressive (CIS) therapy (CIS group, a combination of ATG, CSA and high-dose immunoglobulin). Peripheral blood lymphocyte subsets levels were measured with a flow cytometer.

RESULTSAt the first stage, in the IS group, the percentage of overall and complete responders was 83.3% and 69.4%, respectively, which was significantly higher than that of the control group (34.3% and 17.1%). Twenty-three patients with MAA progressed to SAA. In the control group, 18 patients with MAA progressed to SAA. In the IS group, five patients with MAA progressed to SAA. The 17 patients with MAA who progressed to SAA were given combined immunosuppressive therapy. The percentage of overall and complete responders was 70.6% and 41.2%, respectively. The level of CD4(+), NK cell ratio decreased but the level of CD8(+) cell increased in MAA children before the treatment. The level of NK and CD4(+) cell was significantly higher in the IS group with the treatment than in the control group.

CONCLUSIONWhen childhood MAA is treated with supportive care alone, more than 50% of patients may progress to SAA. Immune mediated pathological mechanism of MAA might be the base of IS therapy. IS therapy is effective and safe for childhood MAA.CIS therapy given to patients with MAA that was progressed to SAA may also be effective.
