Objective To determine the socio-demographic and clinical correlates of suicide attempts in Chinese schizophrenia outpatients and their impact on patients' quality of life (QOL).Methods Two hundred and fifty eligible subjects were recruited and interviewed using standard instruments. Multiple logistic regression with stepwise method was used.Results The prevalence of suicide attempts was 33.6%. Patients with a history of suicide attempts were more likely to have multiple hospitalizations and poor physical QOL domain. Negative symptoms inversely predicted suicide attempts.Conclusion Suicide attempts could be controlled if more attention is paid on schizophrenia patients with multiple hospitalizations and poor physical QOL domain, which could facilitate the re-entry to community for schizophrenia outpatients in China.

Objective To investigate the effect of propofol on cognitive function in young obese rats, and to explore its relationship with heme oxygenase 1 (HO-1), superoxide dismutase 1 (SOD1) protein expression and plasma S100 calciumbinding protein β (S100β) expression. Methods A total of 140 male SD rats aged 21 days were randomly divided into normal diet group (n=40) and high-fat diet group (n=100), and the rats were fed with a normal diet and a high-fat diet, respectively. After 4 weeks of feeding, 40 rats of the high-fat diet group with body mass≥the average body mass ≥1.4 times of the standard deviation of the normal diet group were designated as obese rats. The rats in the normal diet group were randomly divided into the normal lipid emulsion solvent group (NL group) and the normal propofol group (NP group), and the 40 obese rats were randomly divided into the obese lipid emulsion solvent group (OL group) and the obese propofol group (OP group), with 20 rats in each group. The rats in the propofol groups were intraperitoneally given propofol 100 mg/kg, and those in the lipid emulsion solvent groups (control groups) were intraperitoneally given lipid emulsion solvent 100 mg/kg, once a day for 7 days. On the first day after drug withdrawal, Morris water maze test was performed to evaluate the spatial learning and memory abilities of rats in each group. Meanwhile, the plasma S100β protein content of each group was detected by enzyme-linked immunosorbent assay, the expression levels of HO-1 and SOD1 protein in hippocampus were detected by Western blotting, and the changes of neurons in hippocampus CA1 area were observed by hematoxylin-eosin staining. Results Compared with the OL group, the escape latency time was significantly prolonged on 1-5 days (all P<0.05), the third quadrant residence time was significantly shortened (P<0.05), the times of crossing platform was significantly decreased (P<0.05), the expression of plasma S100β protein was significantly increased (P<0.05), the relative expression levels of HO-1 and SOD1 protein in hippocampus were significantly decreased (both P<0.05), and the number of neurons in hippocampal CA1 area was significantly decreased (P<0.01) in the OP group. Compared with the NL group, the escape latency time of the NP group was significantly prolonged on 1-2 days (both P<0.05), and there were no significant differences in other indexes mentioned above (all P>0.05). Conclusion Propofol can down-regulate the expression of anti-oxidant factors HO-1 and SOD1 in the hippocampus of young obese rats, leading to increase of S100β expression and oxidative stress and eventually causing cognitive impairment..

Objective To investigate the effect of mircoRNA-128-3p (miR-128-3p) on epithelial-mesencfrymal transition (EMT) of ovarian cancer cells and its regulatory mechanism on zinc finger E-box binding homobox 1(ZEB1). Methods Real-time PCR technology was used to detect the expression of miR-128-3p in epithelial ovarian cancer tissue (EOC) and adjacent normal tissue (30 cases each), and to observe whether there was a difference. Two human ovarian cancer cell lines, SK0V3 and A2780, were selected and transfected respectively. MiR-128-3p mimic (miR-128-3p mimic group) and negative control mimic (NC mimic group) were used to detect the expression of miR-128-3p in 4 groups by Real-time PCR to verify the interference effect. Transwell assay was used. The migration and invasion abilities of the four groups of cells were observed. The regulatory relationship between miR-128-3p and ZEBl was verified by dual luciferase assay, and the expression level of ZEBl protein after overexpression of miR-128-3p was detected by Western blotting; pcDNA-ZEBl was transfected into SK0V3 and A2780 cell lines to make it overexpression of ZEBl was divided into NC mimic group, miR-128-3p mimic group, and miR-128-3p mimic+pcDNA-ZEBl group. Western blotting was used to detect the EMT-related protein E-cadherin in 6 groups of cells and the expression level of vimentin. Results Real-time PCR result showed that the expression of miR-128-3p in EOC tissues decreased compared with that in adjacent tissues (P < 0. 01); The relative expression of miR-128-3p in the miR-128-3p mimic group was higher than that in the NC mimic group, while the numbers of migrating cells and invasive cells were lower than those in the NC mimic group (P < 0 . 0 1) . The result of dual luciferase experiments showed that miR-128-3p had a negative regulatory effect on ZEBl. In SK0V3 and A2780 cells, the relative expression of ZEBl protein in the miR-128-3p mimic group was lower than that in the NC mimic group, while the relative protein expression of E-cadhein was higher than that in the NC mimic group (P < 0 . 0 1) . The relative protein expression of E-cadhein in the miR-128-3p mimic+pcDNA-ZEBl group was lower than that in the miR-128-3p mimic group (P < 0 . 0 1) . In SKOV3 and A2780 cells, the relative protein expression of vimentin in the miR-128-3p mimic group was lower than that in the NC mimic group, and the relative protein expression of vimentin in the miR-128-3p mimic+pcDNA-ZEBl group was higher than that in the miR-128-3p mimic group (P < 0 . 0 1) . Conclusion The expression of miR-128-3p decreases in epithelial ovarian cancer tissues, which ma)' be due to the regulation of ZEBl to affect the expression of EMT-related proteins and participate in the EMT process of ovarian cancer cells.

On 18th October 2018, a 49 years old man with right thigh proximal medial swelling and pain was received in the Department of Pathology, People′s Hospital of Deyang of Sichuan Province. The patient had experienced amputation twice because of burn in right lower limb 46 years ago. Cicatricial squamous cell carcinoma metastasis in right thigh proximal medial was diagnosed by fine needle aspiration cytology in our hospital. The wound remained ulcered and unhealed after biopsy in a higher level hospital. The patient died in ten days after first chemotherapy which was required by the patient. This case suggests that clinician should perform pathological examination on burn patients with scar ulcer as soon as possible to avoid delay in treatment, which may cause carcinogenesis deterioration and metastasis.

AIM: To study the efficacy of AMSPL on myopia control, and confirm the security of wearing AMSPL, through comparing the impacts on visual parameters between myopic children wearing spectacle lens designed to reduce peripheral hyperopic defocus(AMSPL)and myopic children wearing the standard design control lens(SPL).

METHODS: Totally 50 children aged 8 to 14 years wearing spectacle lens designed to reduce peripheral hyperopic defocus(AMSPL)were collected into the AMSPL group, and other 50 children in the same age, the same degree of myopia and the same glasses time wearing standard design control lens(SPL)were selected into normal control group randomly(SPL group). We reviewed their documents and exam all patients. The examination include intraocular pressure, refraction under cycloplegia, distant strabismus and near strabismus, AC/A ratio.

RESULTS: The children wearing spectacle lens designed to reduce peripheral hyperopic defocus(AMSPL)had lower feeling of comfort than SPL group, mainly in peripheral vision confused, but no difference between them 1mo later. The AMSPL group's average growth of refractive error is -0.62±0.50D, the SPL group's average growth of refractive error is -0.77±0.48D(P=0.072). In myopic children aged 8 to 10 years, the AMSPL group's average development of refractive error is -0.71±0.41D, lower than the SPL group that of -1.05±0.39D, the difference was significant(t=2.164, P=0.041). Between the two groups, there was no significant difference(P>0.05)in visual parameters of distant strabismus, near strabismus, AC/A ratio.

CONCLUSION: Wearing spectacle lens designed to reduce peripheral hyperopic defocus(AMSPL)can delay the progression of myopia to a certain extent, especially for myopic children aged 8 to 10 years. It suggests that wearing AMSPL has the same safety with SPL for myopic children.

AIM: To investigate the effect of docosahexaenoic acid(DHA)on photoreceptor apoptosis and phosphatidylinositol-3-kinase/threonine protein kinase(PI3K/Akt)pathway in age-related macular degeneration(ARMD)rats.

METHODS: The rats were randomly divided into blank control group, model group, low dose DHA group(L-DHA group), medium dose DHA group(M-DHA group)and high dose DHA group(H-DHA group). The rat model of dry ARMD was established by light injury. He staining was used to observe the pathological changes of retina, TUNEL method to detect the apoptosis of retinal cells, transmission electron microscopy to observe the ultrastructure of retinal ganglion cells, enzyme-linked immunosorbent assay to detect the levels of TNF - α and IL-6 in retina, Western blot to detect the expression of p-PI3K, p-Akt, Bax, Bcl-2, p-NF-κBp65 and cleved-caspase-3 protein in retina.

RESULTS: Compared with the blank control group, the total thickness of retina, the thickness of outer nuclear layer and inner nuclear layer, the expression of p-PI3K, p-Akt and Bcl-2 protein in the retina of the model group decreased(P<0.05), the apoptosis index in the ganglion cell layer and outer nuclear layer, the level of TNF-α and IL-6 in the retina, the expression of Bax, p-NF-κBp65 and cleared caspase-3 protein increased(P<0.05). Compared with the model group, the total thickness of retina, the thickness of outer nuclear layer and inner nuclear layer, the expression of p-PI3K, p-Akt and Bcl-2 protein in retina increased in M-DHA group and H-DHA group(P<0.05), the apoptosis index in ganglion cell layer and outer nuclear layer, TNF-α and IL-6 levels in retina, Bax, p-NF-κBp65 and cleved caspase-3 protein expression decreased(P<0.05).

CONCLUSION: DHA may inhibit photoreceptor apoptosis by activating PI3K /Akt pathway.

In recent years, the incidence of idiosyncratic drug-induced liver injury (IDILI) has been increasing, posing a threat to human health. This article reviews the incidence, pathogenesis, and the principles of clinical diagnosis and treatment of IDILI. Because there is limited literature on IDILI in children, so this article simply describes the experience in the diagnosis and treatment of IDILI in children. It is considered that to reduce the incidence of IDILI in children, drug indications should be strictly followed, and molecular test and accurate medical treatment should be promoted.

Autoimmune liver diseases mainly include autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis, and various types of overlap syndromes and are often associated with extrahepatic autoimmune diseases. However, few studies have described the association of autoimmune liver diseases with rheumatic disease and/or skin disease. For this purpose, this article reviews the rheumatic and skin manifestations associated with autoimmune liver diseases in detail and the clinical significance of non-specific antibodies. It is pointed out that individualized treatment should be given to patients with rheumatic disease and/or skin disease.
