Mitochondrial oxidative stress has been recognized as a preliminary and critical factor that aggravates the pathological cascade of Alzheimer's disease, which induces the production of β-amyloid protein, upregulates the expression of phosphorylated tau protein and triggers oxidative damage to lipids, proteins and mitochondrial deoxyribonucleic acid. Central neurons are more vulnerable to oxidative stress than non-neuronal cells due to their high oxygen demand, abundant unsaturated fatty acids and antioxidant enzymes deficiency. On this account, this review introduces the causes of mitochondrial oxidative stress, and analyzes the important role of mitochondrial oxidative stress in the pathogenesis of Alzheimer's disease. Meanwhile, the review focuses on the design and intervention strategies of drug delivery systems targeting mitochondrial oxidative stress in neurons, aiming to provide new ideas for the prevention and treatment of Alzheimer's disease.

Objective To investigate the clinicopathology and immunophenotype of primary non- Hodgkin lymphoma(NHL)of the female genital system,and to analyze the prognosis of such tumors. Methods Clinicopathologic features of 43 cases of primary NHL of the female genital system were studied retrospectively,with the histological classification based on the Classification of Haematopoietic and Lymphoid Tumors(WHO,2001).Immunochemistry technique,in-situ-hybridization and polymerase chain reaction methods were used to detect the immunophenotype,epstein barrvirus(EB)virus infection status and immunoglobulin heavy chain gene rearrangement,respectively.Results(1)Primary lesions:there were 24 cases of lymphoma originating in the ovary,3 cases in the endometrium,10 cases in the cervix,2 cases in the vagina and 4 cases in the vulva.(2)Staging:12 cases(28%)were in stage Ⅰ,9 cases (21%)in stage Ⅱ,and 22 cases(51%)in stage Ⅲ.(3)Histological classification:37 cases(86%)were diffuse large B cell lymphoma(DLBCL),3 cases were Burkitt lymphoma and the remaining 3 cases were unspecified peripheral T-cell lymphoma according to biopsy,immunophenotype analysis,in-situ- hybridization technique and IgH gene rearrangement detection.(4)Prognosis analysis:increase in the level of lactic acid dehydrogenase,stage Ⅲ,DLBCL and single operation suggest poor prognosis.Conclusions Establishment of the diagnosis of primary NHL of the female genital system is based on biopsy, immunophenotype analysis,in-situ-hybridization technique and IgH gene rearrangement detection,which play important roles in diagnosis and differential diagnosis of the tumor.Combined therapy is the first choice of therapeutic regimens.

AIM: To analyze the composition, distribution and characteristics of the elderly primary ocular tumors.
METHODS: This was a retrospective study and all 504 cases with primary ocular tumors aged 60 years or older were collected in Shanxi Eye Hospital, during the year 2000- 2012. The onset age, location and pathological pattern were analyzed.
RESULTS: There were 346 cases of benign ocular tumors (68. 7%), and 158 cases of malignancy (31. 3%). Papillomas was the most common type of the benign with 83 cases (16. 5%), followed by a variety of inflammatory cysts and lesions with 69 cases ( 13. 7%) and 64 cases (12-7%) respectively. Among malignant tumors cases, eyelid basal cell carcinoma originated from epithelial was the most common with 72 cases (14. 3%), followed by skin appendages sources malignant tumors with 39 cases (7. 7%). Concerning the location of ocular tumors, there were 282 cases of eyelid tumor (56. 0%) occupied the first position followed by conjunctival tumor with 157 cases (31. 2%).
CONCLUSION: The prevalence and type of primary ocular tumor in elderly people are significant differences from the general population and children's, and the proportion of malignant tumors tended to increase along with the increase of age.

Currently, clinically used drugs for the treatment of gout inflammation, such as colchicine, nonsteroidal anti-inflammatory drugs, and glucocorticoids, can only relieve the pain of joint inflammation and have severe hepatorenal toxicity and multiple organ adverse reactions. The NOD-like receptor thermal protein domain associated protein 3 (NLRP3) inflammasome is a key complex that induces the onset of gout inflammation and has become a crucial target in the development of anti-gout drugs. This article reviews the research progress of anti-gout small molecules targeting the NLRP3 inflammasome and their bioactivity evaluation methods in the past five years, in order to provide information for the development of specific drugs for the treatment of gout inflammation.

Objective To explore the characteristic and its influencing factors of resilience in Chinese recruits to provide the scientific evidence for the mental health training. Methods Resilience Scale for Adults (RSA) ,Self-report Symptom Checklist 90( SCL-90), Eysenck Personality Questionnaire(EPQ) and General SelfEfficacy Scale (GSES) were applied to 2459 recruits(2231 males and 139 females, aged ( 19 ± 1.5 ) ) within two male recruits( 101.76 ± 14.06) was significantly higher than that of males (96.65 ± 15.62) ( t=4. 13, P＜0. 0l ) ;Recruits with College and above education have significantly higher RSA scores than those with junior high school education and senior high school education (P ＜ 0. 0l ). Between the only child group and non only child group, there was no significant difference in RSA total score , but significant difference existed only in three factors higher RSA group scored significantly higher in extraversion (Z = 19.13, P = 0.000), abreaction adjustment (Z =8.67, P = 0.600 ) and self-efficacy (Z = 19.48, P = 0.000 ), while scored significantly lower in the SCL-90 (Z =Resilience had significant positive correlation with extraversion, abreaction adjustment and self-efficacy, and negative correlation with the neuroticism and inhibition adjustment. Multiple linear regression analysis revealed that extraversion, neuroticism,abreaction adjustment/inhibition adjustment and self-efficacy had predictive ability to resilience( explain 41% ). Conclusion Chinese recruits have good resilience. Emotion Regulation (abreaction adjustment/inhibition adjustment), extraversion, neuroticism and self-efficacy are important influencing factors of resilience for Chinese recruits.

Objective To evaluate the possible interactions among different impact factors possibly affecting the treatment efficacy of 131I in Graves′ disease (GD). Methods Six hundred and thirty two GD patients that had been treated by 131I, with or without antithyroid drugs (ATD), were included in this study. The impact factors were pre-defined as age (x1), sex (x2), mass of thyroid (x3), course of disease (x4), initial symptom (x5), condition of disease (x6), ATD treatment duration (x7), effective half life time (x8), maximum 131I uptake rate (x9), total dose of 131I (x10), dose of 131I per gram of thyroid (x11), TRAb (x12), TSI (x13), TgAb (x14), and thyroid microsomal antibody(TMAb) level(x15). Interactions among different impact factors were studied by t-test, χ2 test and multi-variant logistic regression. Results Age, mass of thyroid, ATD treatment duration, maximum 131I uptake rate, dose of 131I per gram of thyroid tissue and TSI level were identified as independent impact factors affecting the 131I treatment efficacy on GD (χ2=6.908, t=-4.063, χ2=13.558, t=-2.553, t=4.528, χ2=9.716, all P<0.05) by uni-variant and multi-variate analyses. Loglinear and general linear model analyses showed that there existed multiple multiplicative and additive interactions among the factors of age, mass of thyroid, ATD treatment duration and maximum 131I uptake rate (likelihood χ2=8.176, P>0.05; F=2.928, 1.992, 2.629, 2.215, all P<0.05), which indicated that the treatment efficacy with co-existing multiple factors was not equal to simple summation of single factors. Conclusions The interactions among multiple factors can cause indi-rect effect on 131I treatment, which might guide the prescription of 131I dosage for GD treatment.

Objective To investigate clinical manifestation of unspecified functional bowel disorder (UFBD), the features of coexistence with functional gastrointestinal disorder (FGID) and its relationship with psychological factors and sleep disturbance in the Chinese Army servicemen.Methodsc FGIDs were diagnosed based on the RomeⅢ Modular Questionnaire. The subjects were 189 servicemen with UFBD (UFBD group) and 372 without FGID (control group). All subjects completed symptom checklist 90 (SCL-90) and Pittsburgh Sleep Quality Index (PSQI) questionnaire.Results'Have to rush to the toilet when having a desire to defecate' was the most frequent symptom of UFBD (93.7%). More than one half of UFBD patients had the symptom 'a feeling of incomplete emptying as bowel movements' or 'straining during bowel movements'. Twenty-eight percent of UFBD subjects had combined FGID (namely cFGID). Among them, the most frequent was proctalgia fugax (7.9%), followed by cyclic vomiting syndrome (6.3%), functional fecal incontinence (6.3%), functional dyspepsia (4.8%) and belching (4.8%). The UFBD group scored significantly higher than the control group in the global severity index (GSI) and in all SCL-90 subscales (P<0.05). The scores of the four domains (sleep quality, sleep latency , sleep disturbance and daytime function disorder), total PSQI score and proportion of poor sleeping quality were significantly higher in the UFBD group than in the control group (P<0.05). The subjects scored significantly higher in combined FGID group than in UFBD group in GSI and in all of SCL-90 subscales, except for phobic anxiety subscales (P<0.05). However, there was no significant difference in each domain, total PSQI and proportion of poor sleeping quality between the cFGID group and UFBD group (P>0.05).ConclusionPathogenesis of UFBD may be closely correlated with psychiatric and psychological factors and sleep disturbance. cFGID are associated with an increased severity of psychopathological features.

The principle of meridian theory in the processing of Chinese materia medica has the same features as the targeting drug delivery in pharmaceutics.Both of them are preparation methods which can change the distribution of drugs,reduce the toxic and side effects as much as possible and enhance the therapeutic effects.However,the target sites of them and the strategies are quite different.The targeting site of the traditional Chinese medicine in the processing of Chinese materia medica is guided by the theory of traditional Chinese medicine and consisted of one or several organizations with a certain degree of integrity.However,most of the target drug delivery are reach to physiologic tissues,organs,cells or organelles with significant accuracy.In addition,the meridian theory in the processing of Chinese materia medica is mainly based on the drug processing,focusing on the change of the material basis through the process to achieve the purpose.The targeting preparation focus on the design of new functional materials to build smart carrier transport drugs to the destination.This article refers to the relevant literature,selects the representative research,discusses the difference and connection between the two concepts,provides some reference to explain the meridian theory,and provides a useful reference for finding a new strategy of targeting drug delivery.

AIM To compare the effects of sealed moistening with brine,simple stir-frying and stir-frying with brine on the contents of psoralen,psoralen,psoralen and psoralen in Psoraleae Fructus aqueous extract.METHODS The HPLC analysis of aqueous extract was performed on a 30 ℃ thermostatic Hibar C1s column (250 mm × 4.6 mm,5 μm),with the mobile phase comprising of 0.1％ formic acid-methanol flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelength was set at 246 nm.RESULTS Compared with the raw product,the contents of glycosides and total components in the product processed with sealed moistening with brine were significantly decreased.Stir-frying with brine could significantly promote the dissolution of glycosides (psoralen and psoralen),but had no significant effect on that of aglycones (psoralen and isopsoralen).Simple stirfrying markedly increased the contents of various constituents.CONCLUSION Both simple stir-frying and stir-frying with brine can significantly increase the total content of four constituents in Psoraleae Fructus aqueous extract.
