Background At present,researches about retinitis and acquired immunodeficiency syndrome (AIDS) mainly focus on observation and analysis of the cytomegalovirus (CMV)-induced ocular complication.To screen the effective drugs is very important for the treatment of AIDS-related CMV-induced retinitis.Objective This study was to describe the clinical features,diagnosis and treatment outcome of CMV-induced retinitis with BAY 38-4766 and evaluate the relationship between CMV retinitis and AIDS.Methods This was a case observational study.A total of 154 eyes of 84 patients with CMV retinitis and AIDS were enrolled in this study.Before the definitive diagnosis of CMV retinitis,the AIDS course of these patients were 4-26 months.In the initial examination,the visual acuity ranged from finger counting to 0.4,and the number of CD4+ T-lymphocyte was 0-30 cells/μl.The survival time in the patients ranged from 3 weeks to 18 months.BAY 38-4766 was used in 117 eyes of 62 patients,and 102 eyes of 53 patients showed the srinked of retinal lesion and improvement of vision (0.1-0.7).BAY 38-4766 was used to treat the CMV retinitis in 117 eyes of 62 patients with the initial intravenous dose of 5 mg/kg,twice per day for consecutive 2 weeks and followed by oral dose 1 gram per day.The follow-up duration was 2 weeks to 18 months.The fundus feature,visual acuity and CD4+ T-lymphocyte counts were analyzed.This study proposal was approved by Ethic Committee of the 474th Hospital of PLA,and written informed consent was obtained from each patient prior to entering this study.Results The numbers of CD4+T-lymphocytes increased to 12-402 eells/μl after administration of BAY 38-4766.The CMV retinitis aggravated and the vision decreased in the untreated 22 patients with the CD4+T-lymphocytes 0-30 cells/μl.Conclusions CMV retinitis is the most common intraocular complication in patients with AIDS.Diagnosis of CMV retinitis is based on the characteristics of necrotizing retinitis,which is typically associated with retinal hemorrhage and vasculitis.BAY 38-4766 is an effective drug for the treatment of CMV retinitis.

AIM: To evaluate the effect of flavored Siwu granules in the clinical adjuvant treatment for phlegm and blood stasis mutual junction retinal vein occlusion.
METHODS: Sixty patients (60 eyes) were randomly divided into treatment group and control group, both with retinal laser photocoagulation and intravitreal injection of triamcinolone acetonide, but the treatment group used flavored siwu granules. Vision, fundus change, fundus fluorescein angiography, clinical syndrome of traditional Chinese medicine ( TCM ), hemorheology examination and safety assessment were evaluated before and 8wk after treatment.
RESULTS: At 8wk after treatment, there were differences on vision improvement, retinal circulation time, whole blood low shear viscosity and total efficient rate of clinical syndrome of TCM, compared with control group(P<0. 05).
CONCLUSION: Flavored siwu granules adjuvant for phlegm and blood stasis mutual junction retinal vein occlusion can improve visual acuity and reduce the eye complications.

To investigate the therapeutic effect of artesunate on mouse cytomegalovirus pneumonia, the BALB/c-nu mice were infected with murine cytomegalovirus-green fluorescent protein (MCMV-GFP) by nose dropping method. The experimental protocol was approved by the Medical Laboratory Animal Ethics Committee of Guangzhou Medical University. The BALB/c-nu mice were randomly divided into five groups: control group, MCMV pneumonia group, and artesunate (60, 120, and 240 mg·kg^-1) groups. The survival rate, weights, and virus loads in lungs among the groups were observed. The degree of histopathologic changes in lungs was assessed directly by hematoxylin-eosin (HE) assay. MCMV-GFP expression was assessed by immunofluorescence. In addition, reverse transcription polymerase chain reaction (RT-PCR) analysis was performed to investigate the content of major immediate early 1 (Mie1) mRNA, and enzyme-linked immunosorbent assay (ELISA) was used to detect the changes of inflammatory factors, interleukin 10 (IL-10), IL-6, and tumor necrosis factor-α (TNF-α). Western blot analysis was used to detect the expression of the changes of nuclear factor-kappa B (NF-κB) signaling pathways in total proteins. Compared with MCMV group, artesunate (120 mg·kg^-1) significantly increased body weights of MCMV-infected nude mice over 30 days, and decreased the viral titer in lung homogenate, lung inflammation, and histological severity. Moreover, the administration of artesunate (120 mg·kg^-1) could downregulate the expression of phospho-NF-κB (p-NF-κB) p65 in the lungs of mice. The present study suggested that artesunate can protect the immunocompromised mice from MCMV-induced interstitial pneumonia via downregulating NF-κB signaling pathway, thus attenuating inflammation in the lungs.

The development of printing ink is a challenge for binder jetting 3D printed preparations, which directly determines the quality of the printed product. This study adopted a 2³ full-factor Design of Experiment (DoE) with three central points to optimize the printing ink composition of levetiracetam 3D printed dispersible tablet based on the concept of Quality by Design. Firstly, using polyvinyl pyrrolidone K30, glycerin and polysorbate 20 as independent variables based on 40% (v/v) isopropanol aqueous solution, and weight variation, hardness, friability and dispersion uniformity of the printed tablets were used as dependent variables. Then obtained the design space of the printing ink prescription by DoE model analysis, and the response optimizer was used to obtain the optimal printing ink prescription: isopropanol aqueous solution containing 0.1% (w/w) polyvinyl pyrrolidone K30 and 4.0% (w/w) glycerin. The jetting mechanism and wettability of the printing ink were analyzed, and different strengths of personalized 3D printed tablets were prepared and characterized, which verified the rationality of the printing ink formulation. This study provided a reference for the development of printing ink for binder jetting 3D printed preparations.

Toxicogenomics (TGx) refers to a set of technologies that assess genome-wide responses after toxic agent exposure. Altered gene expression patterns that are caused by specific exposures reveal how toxicants may disrupt cellular processes and lead to side effects. Development and application of " omics" technology facilitate the toxicogenomic research which sharing and interpretation of the enormous amount of biological information generated in toxicologic field. In recent years TGx has been widely valued and successfully applied as an effective research tool to evaluate the toxic effects of traditional Chinese medicine (TCM). Here we reviewed current progress in the field of TGx and focused on its application in traditional Chinese medicine safety evaluation, especially in revealing the mechanism, finding potential toxic biomarkers and studying compatibility detoxification of TCM.

OBJECTIVETo observe the impacts of the acupoint catgut implantation on postpartum pain of uterine contraction with qi and blood deficiency.

METHODSOne hundred and ten primiparas of natural delivery differentiated as qi and blood deficiency pattern in TCM were selected as the subjects. They were randomized into an acupoint catgut implantation group (55 cases) and a routine nursing group (55 cases). In the acupoint catgut implantation group, the catgut was implanted in Zigong (EX-CA 1), Zusanli (ST 36), Sanyinjiao (SP 6), Pishu (BL 20) and Geshu (BL 17) in 6 h after delivery; additionally, the routine post-delivery nursing was adopted. In the routine nursing group, the routine post-delivery nursing was applied simply. Visual analogue scale (VAS) and the pain relief time of uterine contraction were compared in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation between the two groups.

RESULTSVAS Scores in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation in the acupoint catgut implantation group were lower apparently than those in the routine nursing group (3.31 +/- 0.39 vs 4.31 +/- 0.29, 1.86 +/- 0.29 vs 2.66 +/- 0.25, 0.89 +/- 0.21 vs 1.59 +/- 0.24, 0.35 +/- 0.10 vs 0.69 +/- 0.13, all P < 0.05). The pain relief was achieved in (72.06 +/- 6.83) h in the acupoint catgut implantation group and was (123.42 +/- 11.12) h in the routine nursing group. The pain relief in the acupoint catgut implantation group was achieved more quickly (P < 0.01).

CONCLUSIONThe intervention of acupoint catgut implantation in 6 h after natural delivery in primiparas prevents effectively postpartum pain of uterine contraction.
