1.Coats disease-like retinopathy and inherited metabolic disorders or syndromes
Chinese Journal of Ocular Fundus Diseases 2017;33(1):93-96
Coats disease is a relatively rare and idiopathic disorder characterized by retinal telangiectasia and massive intra-retinal and (or) sub-retinal lipid accumulation, resulting in complications including retinal detachment and neovascular glaucoma. Previous reports have revealed that Coats disease can be associated with other disorders, especially some inherited diseases, such as retinitis pigmentosa (RP) and facioscapulohumeral muscular dystrophy (FSHD). Coats disease associated with other inherited disorders is generally called Coats-like retinopathy, which has some unique features that differs from the classic Coats disease, for example there is no sex and age preference, more bilateral cases, more severe cases and more genetic factors involved. Patients of Coats-like retinopathy with RP and FSHD may have mutations in Crumbs homologue gene 1 and D4Z4 genes.

To interpret the traditional Chinese medicine (TCM) theory by the network technology, in order to promote the modernization and programming of studies on compatibility of TCMs. In this paper, efforts were made to express the direct interactions between drugs through the herb-pair network, analyze the community characteristics of the network and its relations with blood-Qi theory, and study the expression of blood-Qi theory on the herb-pair network through prescriptions. According to the findings, the herb-pairs network showed a strong community structure characteristics; Each community is composed of a series of herb pairs with close correlations, and either blood efficacy or Qi efficacy but not both of them. Based on that, the 386 single TCM ingredients involved by the herb-pair network were divided into three types of communities: Blood (B) community, Qi (Q) community and uncertain community. According to the statistical results of 262 prescriptions mapped onto the three types of communities, if a prescription contains single herbs of the Q community, the probability that it contains single herbs o the B community is 99.84%; Meanwhile, there are 140 prescriptions containing single herbs of both the Q community and the B community. The result is completely coincident with the TCM Blood-Qi theory that single herbs belong to both Q and B communities or the B community, because Qi regulation leads to blood regulation, but not vice versa. For example, a patient with hemorrhage due to trauma or blood-heat, Qi tonifying prescriptions may aggravate hemorrhage. In this paper, authors found high-recognition macroscopic network numerical characteristics to network data reference for judging rationality of new prescriptions, and proved human blood and Qi relations from the perspective of data analysis.

9.Effect of oxidative stress on human Wiskott-Aldrich syndrome related protein 2 expression in placental trophoblasts in preeclampsia
Chinese Journal of Perinatal Medicine 2013;16(7):422-428
Objective To explore the effect of oxidative stress on human Wiskott-Aldrich syndrome related protein 2 (WAVE2) expression in placental trophoblasts in women with preeclampsia.Methods (1) Twenty women with preeclampsia and twenty-three normal term pregnant women,delivered from August 15,2011 to February 23,2012 in the First Affiliated Hospital of Chongqing Medical University,were recruited and divided into preeclampsia group and control group.Placenta samples were collected after cesarean section.The localization and distribution of WAVE2 in placenta was studied by immunohistochemistry.Quantitative real-time polymerase chain reaction and Western blot were employed to assay the WAVE2 mRNA and protein levels.Tissue homogenates was applied to determine the levels of reactive oxygen species (ROS).The correlation between ROS levels and WAVE2 was also analyzed.(2) An in vitro hypoxia/reoxygenation (H/R) model was utilized to simulate ischemia/reperfusion injury to placental trophoblasts.The HTR-8/ SVneo cells (immortalized human first trimester extravillous trophoblast cells) were pre-incubated overnight,after exposure to H/R or normoxic conditions for 48 hours.Flow cytometry was employed to analyze intracellular ROS level.Meanwhile,Transwell assay was utilized to analyze the invasion and migration of HTR-8/SVneo cells.The location and expression of WAVE2 in trophoblasts was evaluated by cell immunofluorescence and Western blot.Statistical differences between the two groups were evaluated by independent t-tests.Pearson's correlation coefficient test was used for correlation analysis.Results (1)Compared with the control group,preeclampsia group had significantly higher 24-hour proteinuria [(1.96±0.24) g vs (0.08±0.05) g,t=19.436,P<0.05],systolic blood pressure [(154 ± 13) mm Hg vs (98 ±11) mm Hg,t=11.324,P<0.05] and diastolic blood pressure [(105±14) mm Hgvs (69±8) mm Hg,t=9.612,P<0.05].In addition,the placental weight and birth weight of infants in preeclampsia group were significantly reduced as compared to the control group [(432±53) g vs (536±67) g,(2446± 187) g vs (3207± 233) g,t=14.562 and 16.307,allP<0.05)].The WAVE2 mRNA level (0.28±0.07 vs 1.01±0.02,t=12.747,P<0.05) and the WAVE2 protein levels (0.63±0.08 vs 1.34±0.19,t=11.648,P<0.05) were also significantly decreased in preeclampsia groups.The level of ROS in placenta in the preeclampsia group was significantly higher than in control group [(144.22 ± 12.32) nmol/(mg · prot) vs (75.17 ± 8.71) nmol/(mg · prot),t=20.467,P<0.05].There was significant negative correlation between ROS level and WAVE2 protein expression in preeclamptic placenta (r =-0.726,P =0.000).(2) In vitro study showed that,the levels of ROS in normoxia group and H/R group was (82.9±5.8)% and (155.6±8.1)%,(t=12.747,P<0.05).Compared with normoxia condition,decreased cell invasion and migration were found in HTR-8/SVneo cells in H/R group [(51.9 ± 3.3)% and (58.4 ±4.2)% respectively,t=11.034 and 13.839,P<0.05].Results from the cell immunofluorescence showed that WAVE2 protein located in the cytoplasm of HTR-8/SVneo cells,and the expression of WAVE2 protein was significant decreased in HTR-8/SVneo cells after exposure to H/R for 48 h (0.37±0.05 vs 0.76±0.06,t=8.631,P<0.05).Conclusions Excessive oxidative stress in preeclamptic placentas was correlated with the decreased expression of WAVE2.H/R-induced oxidative stress could decrease WAVE2 expression,which may contribute to impaired trophoblast invasion and migration in preeclampsia.

Gonorrhea is a sexually transmitted disease caused by Neisseria gonorrhoeae,and substantially harms human health and socioeconomic development.Due to inappropriate treatment and the presence of drug resistance genes in patients,antibiotic resistance has emerged in Neisseria gonorrhoeae,such as resistance to penicillin,tetracycline,ciprofloxacin,or other antibiotics.Currently,extended-spectrum cephalosporins (ESCs) are the first-line treatment of gonococcal infection.With the wide use of ESCs,the sensitivity of Neisseria gonorrhoeae to ESCs has been decreasing gradually,and there have been reports on cases of treatment failure in clinical practice.In order to control gonorrhea and deal with drug resistance in Neisseria gonorrhoeae,combined therapy,alternative therapy and new drugs have been developed in clinic.
