Objective To explore the sleep quality in patients with psoriasis. Methods Twelve psoriatic patients and 19 normal controls were examined by means of polysomnography (PSG). Results Light sleep increased markedly, but medium and deep sleep decreased in psoriatic group. Hypopnea index, apneahypopnea index, lowest oxygen saturation in arterial blood,

Objective To explore the value of Toll-like receptor 2(TLR2) on the diagnosis of neonatal septicemia especially for the early diagnosis.Methods Twenty-two newborns with septicemia were divided into 2 groups according to the time of onset:early-onset group(n=12) and late-onset group(n=10).Another 14 non-infectious newborns were collected as control group.The TLR2 mRNA in peripheral blood was detected by real-time polymerase chain reaction,and mononuclear cells were isolated by the density gradient centrifuga-tion;the C reaction protein(CRP) was detected,and the co-relationship of the indexes was analyzed by Pearson correlation analysis.Results 1.The level of CRP in early-onset group were(157.89?32.96) ng?L-1,and(89.78?16.24) ng?L-1 in late-onset group,and there was significant difference between both groups(P=0.001);(6.91?1.20) ng?L-1 in control group,which was significantly lower than that in early-onset group and late-onset group(P=0.000,0.001).2.The expression of TLR2 mRNA in early-onset group and late-onset group was(57.38?10.72)?1012 copies?L-1and(32.74?4.65) ?1012 copies?L-1,which was significantly higher than that in control group[(4.12?0.68) ?1012 copies?L-1].3.CRP is positively correlated with TLR2 mRNA(C=0.972,P=0.000).Conclusions TLR2 expression is proven to be related to both the level of CRP and the stage of onset and may play a key role in the pathogenesis of neonatal septicemia.Detection for TLR2 may assist the earlier diagnose of atypical neonatal septicemia.

Objective To explore the clinical features, surgical techniques and treatment efficacy of blood blis?ter-like aneurysms (BBA) of the internal carotid artery (ICA). Method We retrospectively reviewed 45 BBAs of the ICA treated surgically at our department between Jan. 2006 and Jan. 2016. The data was analyzed. Results Direct clipping of BBA was performed in 38 patients, clipping over wrapping in 3 patients and trapping of ICA in 4 patients. Intraoperative rupture occurred in 12 patients (27%). Postoperative cerebral infarction developed in 10 cases (22%). Seven patients died (16%). During the follow-up time of 47 months (range, 6~126 months), Good results were achieved in 34 patients (76%) with a modified Rankin Scale (mRS) 0~2 and 4 patients were in mRS 3~5. Follow-up angiography revealed a re?currence of BBA in one patient, which was retreated with endovascular coiling. No rebleeding was found in all fol?lowed-up patients. Conclusions BBAs of the ICA are difficult to treat surgically with high risk and complications. Thoughtful pre-operative evaluation of BBA and application of various surgical strategies during operation can signifi?cantly reduce the surgical risk and achieve good outcomes.

Aim To discuss the influence of endosome/ lysosome transport proteins SNX10 on macrophage, providing new potential targets for the treatment of variety of related immune diseases . Methods The genotype of mice was identified by PCR. The role of SNX10 in phagocytosis of bacterial components and sterilization by macrophages were assessed. The levels of TNF-α、IL-12 / 23 p40 and IL-6 were measured by q-PCR and ELISA assay. Finally, the NF-κB signaling pathway was evaluated by Western blot and immuno-fluorescence staining. Results Ex vivo experiments showed that SNX10 knockout could enhance bactericid-al ability and inhibit the expression and production of TNF-α, IL-12 / 23 p40 and IL-6 of macrophages.These effects might attribute to the inhibition of NF-κB signaling pathway activation. Conclusion SNX10 knockout could enhance bactericidal ability and inhibit the inflammatory response of macrophages, and its mechanism may be achieved through the NF-κB signa-ling pathway.

To investigate the protective effect of curcumin on endotoxin-induced acute lung injury in rats, and explore the underlying mechanisms, 24 male Wistar rats were randomly divided into 4 experimental groups: sham-vehicle (S), sham-curcumin (C), lipopolysaccharide (LPS)-vehicle (L), and curcumin-lipopolysaccharide (C-L) groups. The wet/dry (W/D) weight ratio of the lung and bronchoalveolar lavage (BAL) fluid protein content were used as measures of lung injury. Neutrophil recruitment and activation were evaluated by BAL fluid cellularity and myeloperoxidase (MPO) activity in cell-free BAL and lung tissue. The levels of cytokine-induced neutrophil chemoattractant-I (CINC-1) in lung tissues were measured by ELISA. The histopathological changes of lung tissues were observed by using the HE staining. Our results showed that lung injury parameters, including the wet/dry weight ratio and protein content in BALF, were significantly higher in the L group than in the S group (P<0.01). In the L group, higher numbers of neutrophils and greater MPO activity in cell-free BAL and lung homogenates were observed when compared with the S group (P<0.01). There was a marked increase in CINC-1 levels in lung tissues in response to LPS challenge (P<0.01, L group vs S group). Curcumin pretreatment significantly attenuated LPS-induced changes in these indices. LPS caused extensive morphological lung damage, which was also lessened after curcumin pretreatment. All the above-mentioned parameters in the C group were not significantly different from those of the S group. It is concluded that curcumin pretreatment attenuates LPS-induced lung injury in rats. This beneficial effect of curcumin may involves, in part, inhibition of neutrophilic recruitment and activity, possibly through inhibition of lung CINC-1 expression.

Objective To investigate the radiologic and angiographic findings of dilated superior ophthalmic vein(SOV)associat- ed with orbital arteriovenous malformations(AVM).Design Retrospective case series.Participants Six cases of orbital AVM patients, with clinical symptoms and signs mimicking a carotid cavernous fistula(CCF).Methods Examinations of the six cases,such as CT, MRI,and selective cerebral angiography,were summarized and analyzed.Main Outcome Measures Images findings and hemodynam- ics.Results All patients were found with dilated SOV on CT and MRI.Additional radiographic findings included proptosis and AVM. All six AVM were located at the orbit,and one of them was also found with AVM in brain.The main draining vein was SOV in all cas- es.The branches contributing to the fistula's blood supply were the middle meningeal artery,the internal maxillary artery,and the oph- thalmic artery.Conclusions Orbital AVM can cause similar clinical signs and radiologic features to those associated with a CCF.How- ever,the bulging cavernous sinus cannot be found in most AVM.Angiography is necessary for definitive management,non-invasive techniques have an important role in pre-angiographic diagnostic decisions.(Ophthalmol CHN,2007,16:395-398)

Objective To evaluate the efficacy of methylprednisolone pulse therapy in the treatment of thyroid-associated oph- thalmology. Design Meta analysis. Participants Published literatures about methylprednisolone pulse therapy for thyroid-associated ophthalmopathy. Methods A meta-analysis of published randomized clinical trials was used. Published literatures were selected for study based on a computerized search of the literature and a manual search of the bibliographies of relevant papers. Studies meeting se- lected criteria were reviewed systematically by meta-analysis. Data was extracted on the basis of the intention-to-treat principle. Treat- ment effect was measnred as relative risk(RR) of response rates. Main Outcome Measures The effective rate and the relative risk(RR). Results A total of 6 articles were included in this meta-analysis. The RR (95%CI) were 7.50 (1.14, 49.26) when comparing methylpred- nisolone pulse therapy with placebo, 3.33 (0.51, 21.89) when comparing methylprednisolone pulse therapy with surgical decompression, and 1.50 (1.12, 2.00) when comparing methylprednisolone pulse therapy with oral steroids. The combination of methylprednisolone pulse therapy and orbital radiotherapy was significantly effective than oral steroids combined with orbital radiotherapy which pooled RR (95% CI) was 1.42 (1.11, 1.81). Conclusions Methylprednisolone pulse therapy appears to be an effective treatment for thyroid-associated ophthalmology, and seems to have increased effect when given with orbital radiotherapy.

OBJECTIVETo observe clinical efficacy in treating cutaneous deficiency of traumatic shank amputation stump with full-thickness skin graft combined with vacuum sealing drainage.

METHODSFrom September 2009 to December 2012, 15 patients with cutaneous deficiency of traumatic shank amputation stump were treated with full-thickness skin graft combined with vacuum sealing drainage. Among patients, there were 11 males and 4 females with an average age of 41.5 (ranged from 25 to 62) years old. Ten cases were caused by traffic accident and 5 cases were caused by heavy object, 9 cases on left and 6 cases on right. Six patients with smashed wound were treated with debridement and amputation, combined with vacuum aspiration in-emergency; 9 patients caused by infection and necrosis were treated with debridement and amputation, combined with vacuum aspiration, and full-thickness skin graft were performed at stage II. The skin defect area of residual limbs ranged from 40 cm x 20 cm to 25 cm x 15 cm.

RESULTSAll patients were followed up from 3 months to 1 year. Full-thickness skin graft of residual limbs were survived,and obtained satisfactory walking function with prosthetic. Residual skin increased thicken, wearproof without rupture and pain.

CONCLUSIONFull-thickness skin graft combined with vacuum sealing drainage in treating cutaneous deficiency of traumatic shank amputation stump could reserve the length of residual limbs, increase survival rate of skin graft with less scar of survival skin, get good wearability and it is conducive to prosthetic wear. It is a simple and easy treatment method.

Roles of sympathicus, sensory neuropeptides (SNP), metabolites of cyclooxygenase, metabolites of lipoxygenase, endothelium derived relaxing factor (EDRF), reactive oxygen (ROS) and potassium channels (PC) in the hypoxic pulmonary vasoconstriction (HPV) and hypoxic cerebral vasodilation (HCVD) were studied in intact rats, rabbits and dogs. Results were as follows: during hypoxia, the excitation of sympathicus results in a constriction of both pulmonary and cerebral vessels; SNP, EDRF and the opening of 4-AP sensitive PC caused the dilation of both of them; metabolites of lipoxygenase mediated HPV and HCVD, whereas metabolites of cyclooxygenase were their modulators; hypoxia induced blockade of the ATP sensitive PC mediated HPV, but had no effect on HCVD; reduction of O_2~+ in the lung might potentiate HPV, but had no effect on HCVD. It is suggested that the alteration of lipoxygenase metabolites, ROS and ATP sensitive PC are factors accounting for the difference in response of pulmonary and cerebral vassels to hypoxia.
