Objective To compare the curative effects of CT-guided ethanol injection and lauromacrogol injection into the sac cavity in treating ovarian endometriosis cysts. Methods A total of 86 patients with ovarian endometriosis cyst were enrolled in this study. The patients were divided into ethanol group (n=44) and lauromacrogol group (n=42). Under CT guidance, injections of ethanol or lauromacrogol into the sac cavity of ovarian endometriosis cysts were respectively performed for the patients of both groups. The patients were followed up for six months, and the curative effects and the complications were analyzed. Results Six months after the treatment, the cure rates of ethanol group and lauromacrogol group were 95.50%and 92.86%respectively, and no statistically significant difference in cure rate existed between the two groups (P>0.05). The preoperative serum CA125 levels of the ethanol group and lauromacrogol group were (48.42±23.68)μg/L and(49.21±22.83) μg/L respectively, and the post operative ones were (23.56±5.89) μg/L and (25.49± 6.10) μg/L respectively; the differences between the preoperative data and the postoperative data were statistically significant in both groups (P<0.05), although the differences in serum CA125 levels between the two groups were not significant (P>0.05). The incidence of postoperative complications in the lauromacrogol group was obviously lower than that in the ethanol group (P<0.05). The cure time in the ethanol group was shorter than that in the lauromacrogol group, although the difference was not significant after six months. Conclusion For the treatment of ovarian endometriosis cysts, CT-guided lauromacrogol injection into the sac cavity has reliable curative effect. Compared to ethanol injection, injection of lauromacrogol is safer and has fewer adverse reactions. Therefore, this technique should be recommended in clinical practice. Serum CA125 can be used as an indicator for the evaluation of curative effect.

Prolyl-4-hydroxylase domain (PHDs) family is one of the most important regulatory factors in hypoxic stress. PHD2 plays a critical role in cells and tissues adaptation to the low oxygen environment. Its hydroxylation activity regulates the stability and transcriptional activity of the hypoxia-inducible factor 1 (HIF-1), which is the key factor in response to hypoxic stress. Subsequently, PHD2 acts as an important factor in oxygen homeostasis. Studies have shown that PHD2, through its regulation on HIF-1, plays an important role in the post-ischemic neovascularization. Furthermore, under hypoxic condition, PHD2 also regulates other pathways that positively regulate angiogenesis factors HIF-1 independently. Moreover, recently, several evidences have also shown that PHD2 also affects tumor growth and metastasis in a tumor microenvironment. Based on these facts, PHD2 have been considered as a potential therapeutic target both in treating ischemic diseases and tumors. Here, we review the molecular regulation mechanism of PHD2 and its physiological and pathological functions. We focus on the role of PHD2 in both therapeutic angiogenesis for ischemic disease and tumor angiogenesis, and the current progress in utilizing PHD2 as a therapeutic target.

Objective To observe the effect of polyethylene terephthalates (PET) coated with 58S bioactive glass on graft-bone healing.Methods The PET coated with 58S bioactive glass was used in experimental group,and uncoated PET was used as a control.The coating solution was made of 20％ bioactive glass powder and 80％ gelatin powder (by weight).In our vitro study,4×104/ml MT3T3-E1 cells were cultured in 24-well plates with the coated or uncoated PET,and the MTT and ALP were tested at 1,3,5 days to show the proliferation and the activity of the cells.The SEM and the X-ray photoelectron spectrometer were adopted to analyze the surface characteristics of the fiber.In our vivo study,24 skeletally mature New Zealand white rabbits were randomly divided into two groups,the 58S-PET group and the PET group.Both groups underwent a surgical procedure to establish a tibia-articular tendon-bone healing model.Mechanical examination and histological assay were taken to verify the coating effect in vivo.Results The 58S-PET group showed significantly differences in both the MTT and ALP tests at each time point (3,5 days) compared with the PET group.In the animal experiments,the maximum load increased by time in both groups.At 6 weeks,the load-to-failure was significantly higher in the 58S-PET group [(61.70±6.95) N]than that of the PET group [(45.21±9.78) N].At 12 weeks,the load-to-failure was also significantly higher in the 58S-PET group [(89.25±9.50) N]than that of the PET group [(71.38±6.26) N].In the histological assay,it was found that there was new bone formation in the indistinct interface between the graft and the host bone in both groups at 6,12 weeks,and a stronger binding was seen in the 58S-PET group than in the PET group.Conclusion The 58S-PET could enhance the proliferation and activity of the osteoblast and therefore promote the new bone formation and subsequently leads to a positive effect on tendon-bone healing.

Objective To compare the characteristics of connective tissue disease-associated interstitial lung disease (CTD-ILD) and idiopathic pulmonary fibrosis(IPF). Methods Patients with a diagnosis of ILD from June 2014 to December 2015 were selected in this study and patients with known other causes of ILD were excluded. The clinical manifestation, autoantibody, high resolution chest computed tomography (CT) and blood gas analysis were retrospectively analyzed. Results Six hundred and twenty-eight patients were included in this study. The prevalence of CTD-ILD and IPF were 459 (73.09%) and 169(26.91%) respectively. The age in IPF group was higher than that in CTD-ILD group:(67.10 ± 13.13) years vs. (52.10 ± 14.23) years, and there was significant difference (t =-10.092, P =0.000). The rate of male in IPF group was higher than that in CTD-ILD group: 75.15%(127/169) vs. 28.32%(130/459), and there was significant difference (P=0.000). Autoantibodies were commonly seen in CTD-ILD group and only antinuclear antibody, and anti-SSA antibody and anti-Ro-52 antibody were seen in IPF group. The most common chest images were honeycombing, bullae of lung and pneumonectasis in CTD-ILD group, while the presence of consolidation and small nodular shadow were more common in IPF group. The concurrence of respiratory failure was higher in IPF group compared with that in CTD-ILD group:49.11%(83/169) vs. 13.07%(60/459), and there was significant difference (P<0.01). Conclusions Patients with CTD-ILD and IPF possess distinct characteristics. Overall assessment of clinical manifestation, autoantibody serology, high resolution chest CT and other indicator will be conducive to the differential diagnosis and treatment of ILD.
