Chinese Journal of Behavioral Medicine and Brain Science 2012;(11):1029-1031
Objective To assess the violence risk levels of the community patients with severe mental illness and Analyze the associated factors.Methods A working group composed of psychiatrists,community police,FIMITIC staff,community physicians,neighborhood or village committee members was established.501 community patients with severe mental illness were evaluated with Violence Risk Assessment Scale by working group.While the data of the general demograpbic,medical history and violence history was investigated.Logistic regression analysis was used to explore the factors associated with violence.Results In 501 patients,risk levels of grade 0:124cases (24.8%),grade 1:165 cases (32.9%),grade 2:118 cases (23.5%),grade 3:59 cases (11.8%),grade 4:28 cases (5.6%) and grade 5:7 cases (1.4%).Logistic regression analysis showed four significant risk factors,which were schizophrenia (OR 4.139),no taking medicine (OR 6.883),unstable condition (OR 234.534) the number of previous violence(OR 3.457) (P < 0.05).Logistic regression equation:Logit (severe violence) =-8.511 + 1.420 (schizophrenia) + 1.929 (no taking medicine) + 5.458 (unstable condition) +1.241 (the number of previous violence).Conclusion The results of violence risk assessment and risk factors have directive significance for management of community patients with severe mental illness.

Journal of Leukemia & Lymphoma 2013;22(3):172-174
Objective To study the clinical characteristics and therapeutic effect of the combination of intensive immunosuppression therapy with umbilical cord blood infusion in severe aplastic anemia (SAA) patients with infections.Methods A retrospective analysis of bacterial spectrum and treatment effect was performed for infections occurred in 27 SAA-Ⅰ patients who received antithymocyte globulin (ATG),cyclophosphamide (Cy) and cyclosporine A (CsA) followed by umbilical cord blood infusion.Results The prevalence of infections in 27 SAA-Ⅰ patients was 48.1%,among which 70 % were infected with bacteria (mostly gram-negative bacilli) and 30 % with fungal infection.Upper respiratory tract was the most common site,followed by the blood and lungs.The primary infections occurred at the median time of 9.5 d (-2-10 d)after the immunosuppressive therapy,and the initial infections of ANC were < 0.2 ×109/L.Conclusion Combination of intensive immunosuppression and umbilical cord blood infusion is proven effective in treating SAA-Ⅰ.As a result,infection rate is low and can be controlled with sensitive antibiotics.

Recent Advances in Ophthalmology 2017;37(3):230-234
Objective To dynamically observe the expressions of Toll like-receptor 2 (TLR-2),TLR-4 and inflammatory cytokine IL-1 beta and TNF alpha,and analyze the correlation between TLR-2,TLR-4 and inflammatory response on rat cornea alkali burn.Methods Forty SPF healthy SD rats were excluded the anterior segment disease,the right eye was set as burn experiment and the left eye as normal control,Ⅲ level corneal alkali burn model was established with concentration of 1 mol · L-1 NaOH(At the establishment and after the establishment of the model,the inconsistent degree of corneal bums,the corneal perforation and hyphema in rats,etc.,were removed,and finally randomly selected 32 eligible rats),then were randomly grouped into 3 days,7 days,14 days and 21 days group,8 eyes in each group.The rats were observed and photographed anterior segment of each group,evaluated the corneal inflammation index,then removed the eyeball of the rats in the corresponding time points.The eyeballs were made into pathological tissue section and stained with HE method.The number of inflammatory cells in the cornea was calculated,and the expression of TLR-2,TLR-4,IL-1 beta and TNF alpha was detected in the rat cornea with method of Western blot protein detection at the same time.The differences of each group were analyzed,and the correlation was assessed between TLRs and inflammatory factor.Results There were the expressions of TLR-2,TLR-4,IL-1 beta and TNF alpha in the normal rat cornea,and its expressions were gradually increased after alkali burn,reached the peak at the 7 days,then decreased gradually,the difference of each group (the 3 day,the 7 day,the 14 day,the 21 day) was statistically significant (all P < 0.05).The expressions of TLR-2 and IL-1 beta (r =0.986,P < 0.05),TNF alpha (r =0.986,P < 0.05) were positive correlated.The expressions of TLR-4 and IL-1 beta(r =0.975,P < 0.05),TNF alpha (r =0.990,P <0.05) were positive correlated.Conclusion TLRs participates and may start immune inflammatory response after corneal alkali burn,mediates the production of inflammatory cytokine.
8.The matched control study between medical imaging and pathologic findings in ossification of the ligamentum flavum of the thoracic spine
Chinese Journal of Orthopaedics 2001;0(06):-
Objective To analyze and classify the characteristic of plain X-ray, CT scan, MRI and pathologic findings in ossification of the ligamentum flavum of the thoracic spine. Providing the clinic criterion to verify the extent and progression of ossification of ligaments based on medical imaging findings. Methods Twenty-four patients with thoracic myelopathy due to ossification of the ligamentum flavum underwent surgical decompression posteriorly. There were 18 males and 6 females with age ranging from 42-76 years (mean, 57.9 years). The morphology of ossification on the CT scan was divided into isotype and non-isotype. The signal intensity of ossification was compared with that of spinal cord on T2 stage in MRI, whose results were divided into four types, such as no signal, low signal, iso signal and high signal. There were two types of ossification in pathologic findings, the mature and immature ossification. 73 segments of ossified ligaments removed from surgery were evaluated and classified individually on the base of their X-ray, CT scan, MRI and pathologic findings. 27 segments of ossified ligaments were examined immunohistochemically by use of TGF-?1 antibody. The relationship between classification of X-ray, CT scan, MRI and pathology of the ossified ligaments were compared on the basis of individual segment, to determine whether there was correlation between these findings. Results The relationship between the pathologic findings of the 73 ossified fragments and the manifestation for the CT classification and MRI signal showed: 18 isotype ossification on CT scan turn out to be mature; and among the 55 non-isotype ossification, 51 were immature and 4 were mature. 22 no signal ossifications on MRI were confirmed as mature type; all the 50 low signal ossifications were immature type; and 1 iso signal ossification was immature type. 100% were matched between MRI and pathological findings, 94.5% matched between CT and pathological findings. Conclusion The extent and progression of ossification of ligaments may be verified and predicted clinically on the base of CT scan and MRI findings, which provide the clinic criterion to guide the extent and timing of decompression.
