AIM: To observe the clinical efficacy of adjunctive intravitreous injection with Lucentis for the treatment of neovascular glaucoma ( NVG) .
METHODS:The retrospective case series study included 25 eyes of 25 patients who underwentintravitreous injection with Lucentis. Patients firstly received an intravitreous injection with Lucentis (0. 5mg/0. 05mL), after the regression of neovascularization of the iris, patients accepted different surgical treatments according to different etiopathogenesis condition. Iris, chamber angle neovascularization condition, intraocular pressure, and visual acuity were observed postoperatively. The follow-up duration was 3mo.
RESULTS:After 3-7d of intravitreous Lucentis injecting, iris and chamber angle neovascularization was totally faded in 20 cases (20 eyes) and was not completely faded in 5 cases ( 5 eyes ) . Additional treatments were compound trabeculectomy ( 14 cases, 14 eyes ) , vitrectomy ( 4 cases, 4 eyes ) . The patients' mean intraocular pressure was 43. 42 ± 10. 99mmHg before treatment, which decreased rapidly when they came out of the hospital (14. 26±7. 64mmHg, P<0. 05) and stabilized during the follow-up 3mo (18. 76±5. 96mmHg, P<0. 05). Follow-up at 3mo, visual acuity improved or remained in 20 cases ( 20 eyes ) and decreased in 5 cases ( 5 eyes ) . The complete success, qualified success and failure were 21 eyes, 3 eyes and 1 eye, respectively.
CONCLUSION:Intravitreous injection with Lucentis can be used as an assisted treatment of NVG. According to different etiopathogenesis condition, it is an effective treatment to combine with other treatment methods for NVG.

Objective:To evaluate of the feasibility of low-dose CT(LDCT)in the reconstruction of three-dimensional(3D)model of maxillofacial hard and soft tissues.Methods:Lightspeed 16-slice spiral CT scanner was used to scan one adult cadaveric head specimens with conventional parameters(280 mA)and low dose parameters(200,150,100,50,35,25,15 and 5 mA)respectively;the 3D model of the hard and soft tissues were reconstructed with Mimics 10.01 software,and 3D comparison were carried on with Geomagic 11.0 software.A comparison of the surface morphology of the hard and soft tissues of the 3D models with different scanning parameters was made.Results:With the reduction of the tube current,the model surface became rough gradually.Compared with the 280 mA scan results,the model surface produced by 35 mA scanning was still fairing,when the dose fell to less than 25 mA,the model surface became rough and the exact shape of the model could not be recognized.The same results of model surface were pro-duced after registration.Conclusion:The low-dose (35 mA)CT can be used to reconstruct 3D model of the maxillofacial hard and soft tissues.

Objective To explore the effect of adenovirus carrying pigment epithelium-derived factor(ADV-PEDF)gene treatment on retinal neovascularization of mice with retinopathy of prematurity (ROP).Methods Sixty 7 d C57BL/6J mice were put into the environment with (750?5)mL/L oxygen for 5 days and returned to normal environment to establish animal models of ROP.The eyes in experimental group received an intravitreal injection of 1 ?L of ADV-PEDF,and the same volume of ADV-LacZ was injected into the eyes of mice in control group.The ADPase histochemical staining was used for retinal flatmount to observe changes of retinal vessels.The inhibitory effects of PEDF on retinal neovascularization were evaluated by counting the endotheliocyte nuclei of new vessels extending from retina to vitreous in the tissue-slice.The expression of PEDF in retina were detected by Western blotting.Results The vessels from optic disc were very thin and distorted in eyes of control group in retinal flatmount.There were avascular area around optic disc and neovascular trufts beside avascular area.Compared with control group,regular distributions and no conspicuous avascular area were found in eyes of experiment group in retinal flatmount.The number of the endotheliocyte nuclei of new vessels extending from retina to vitreous was less in the eyes of the experiment group than that in control group (P

Objective: To understand sleep behavior among primary and middle school students and its impact on overweight and obesity changes, to provide evidence for developing obesity prevention and controlling strategies in children and adolescents. Methods: Primary and middle school students from three cities in Zhejiang Province who participated in questionnaire surveys and physical measurements in both 2017 and 2019 were selected. A follow up dataset of 605 students was developed and the relationship between sleep duration and body mass index was analyzed. Results: From 2017 to 2019, BMI Z scores for male and female participants increased by 0.24 and 0.13, respectively. BMI Z scores increased by 0.29 in students of 9-12 years old and increased by 0.11 and 0.25 in urban and rural students, respectively ( P <0.05). The prevalence of insufficient sleep duration increased from 37.0 % to 41.8% simultaneously ( χ 2=3.68, P =0.06). After adjusting for confounding factors, the BMI Z score of students with insufficient sleep was 0.20 higher than those with sufficient sleep duration ( P <0.01). Compared with participants who had sufficient sleep duration from 2017 to 2019, participants whose sleep duration changed from sufficient to insufficient, and those who always had insufficient sleep duration increased by 0.23, respectively ( P <0.05). Conclusion Insufficient sleep duration is a risk factor for obesity. Shortened sleep duration is related to weight gain, and maintaining sufficient sleep duration may reduce the risk of obesity in children and adolescents.

OBJECTIVEConcentration of extracellular calcium ([Ca(2+)](o)) in the central nervous system decreases substantially in different conditions. It results in facilitating neuronal excitability. The goal of this study is to examine the mechanisms of enhanced neuronal excitation in low [Ca(2+)](o) in order to provide new clues to treat the hyperexcitability diseases in clinic.

METHODSWhole-cell patch-clamp technique and neuron culture were used in the study.

RESULTSThe firing threshold of cultured hippocampal neurons decreased markedly in low [Ca(2+)](o) saline. Unexpectedly, apamine and isoprenaline, antagonists of medium afterhyperpolarization (mAHP) and slow AHP (sAHP) respectively, had no statistic significant effect on excitability of neurons. TTX at a low concentration was sufficient to inhibit I(NaP), which blocked the increase of firing frequency in low [Ca(2+)](o). It also reduced the number of spikes in normal [Ca(2+)](o).

CONCLUSIONThese results suggest that in cultured hippocampal neurons, modulation of spiking threshold but not AHP may cause the increased excitability in low [Ca(2+)](o).

Development of the disease is the result of several factors involved in biological network changes. The nature of drug intervention is to regulate these pathological changes to the normal range. Advantages of traditional Chinese medicine (TCM) are to integrally and systematically regulate this biological networks and systematic pathology through multi-targets, multi-levels, multi-channels. Structural components TCM provides the controlled and precise basis "substance" for this regulation and also to clarify the "truth" of the nature of the regulation by the network pharmacology. Network pharmacology provides new strategy for the research on mechanism of structural components TCM. This study not only reflects the overall characteristics of the development of the disease, but also fully embodies the essence of TCM for preventing and treating diseases through changing traditional model on "one drug, one gene, one disease". This paper explores systematically the integration essence, features and research strategies of structural components TCM and the network pharmacology, understand the interaction of structural components TCM and body from the perspective of the overall concept of improving or restoring the balance of.biological networks. It is effective measure to reveal the structure of a multi-component for regulating biological networks mechanisms, and also provide new ideas and methods for further scientific research and innovation of structural component TCM.
