AIM To study the effects of high glucose on the cardiac hypertrophy,cultured cardiomyocytes were used to study the accelerating effects of high glucose on norepinephrine(NE) induced cardiac hypertrophy. METHODS Using cultured myocardial cells as a model, the cellular hypertrophy was observed. The protein content was assayed with Lowrys method. The cardiomyocytes' volumes was measured by computer photograph analysis system. The protein synthesis was assayed with leucine intake method. RESULTS The total cellular protein content?cellular volumes?cellular protein synthesis showed an increase in high glucose group, NE group, high glucose and NE group compared with control group, respectively. High glucose and NE group showed a further increase compared with NE group. CONCLUSIONS The high glucose itself induced hypertrophy of the cultured myocardial cells slightly. Meanwhile high glucose can further accelerate hypertrophy of the cultured myocardial cells induced with NE. The effective mechanism between high glucose and NE on cardiac hypertrophy need further study.

Objective To observe the clinical features, phenotypes and genotypes in a Chinese family with choroideremia (CHM). Methods A Chinese four-generation family (15 members) with CHM, including 5 patients (4 males/1 female), 2 female carriers and 8 healthy members, was enrolled in this study. Initially all family members underwent best corrected visual acuity (BCVA), indirect ophthalmoscopy, fundus fluorescein angiography, optical coherence tomography (OCT), visual field and full view electroretinogram (ERG). BCVA was followed up for 3 years. Venous blood samples were collected, and all of the 15 coding exons and flanking intron regions were amplified in the proband by polymerase chain reaction followed by direct sequencing. Protein structure was modeled based on the protein data bank and mutations in DeepView v4.0.1 to predict the effect of the mutations. A total of 180 healthy volunteers were enrolled as control group to matching CHM gene sequences. Results The visual acuity (VA) of 3/4 adult male patients began to decrease at less than 10, 10 and 30 years old, the average BCVA was 0.43. There were characteristic signs and symptoms of CHM including narrow visual field, extinguished rod and cone response in ERG, disappeared junction line and intermediate line of photoreceptor inner segment/outer segment on OCT. After 3 years, the mean BCVA decreased to 0.11. The BCVA of one young male patient was 1.0 in both eyes with minor changes fundus and visual field. The VA of the female patient began to decrease at 50 years old, her BCVA of two eyes were 0.5 and 0.25, respectively. The fundus changes were typical of CHM, with relative scotomas in the peripheral visual field of OD, and big scotomas in the OS. After 3 years, her mean BCVA decreased to 0.2. Of 2 female carriers, one had minor fundus changes (patches of pigmentary deposits, atrophy spots of retinal pigment epithelium cells), and the other was normal. A novel heterozygous c.1837G>A mutation in exon 15 of CHM was detected in the proband, which resulted in the substitution of serine by proline at codon 613 (p.D613N). Based on molecular modeling, the misfolded protein caused by the mutation might destabilize the structure of the helix that potentially could affect the global stability of the Rep-1 protein. Conclusions A novel c.1837G>A (p.D613N) mutation may be the causative mutation for CHM in this family. Female CHM carriers may have some signs and symptoms.

Background Infectious keratitis is common blinding eye disease in China.Inflammatory runaway reaction often occurs in infectious keratitis, and its mechanism and treating approach are worthy of research.Objective This study was to investigate the clinical manifestation,mechanism and treatment outcome of doxycycline in overwhelming inflammation induced by Pseudomonas aeruginosa keratitis.Methods Pseudomonas aeruginosa suspension was intrastromal injected in 60 right eyes of 60 New Zealand white rabbits,and gatifloxacin eye drops was frequent instilled for consecutive 3 days to establish corneal inflammatory runaway reaction models,and 42 eyes with worse keratitis were defined as overwhelming inflammation.Then the models were randomly divided into gatifloxacin treatment group (15 rabbits), combined treatment group (gatifloxacin with doxycycline treatment, 15 rabbits) and balance salt solution (BSS) control group (12 rabbits), and corresponding eye drops was topically administered in the rabbits 8 times per day for 14 days.The symptoms of the models were observed under the slit lamp microscope on day 1,3,7 and 14 after treatment,and the corneal infiltration area was calculated.The corneal morphology was examined by using hematoxylin-eosin staining.The expressions of matrix metalloproteinase-2 (MMP-2) and MMP-9 in the corneal tissue were examined by immunohistochemistry.The contents of tumor necrosis factor α (TNF-α) and interleukin-1β (IL-1β) in corneal homogenate were detected by ELISA.The use and care of the animals complied with the ARVO Statement.Results The inflammatory scores were lower and infiltration area of cornea was smaller 7 days after treatment than those before treatment in the combined treatment group and gatifloxacin treatment group (both at P＜0.05).Hematoxylin-eosin staining result showed that the inflammation response of cornea subsided 14 days in comparison with 5 days after treatment in the combined treatment group, with the proliferation and rearrangement of fiberal tissue.The MMP-2 and MMP-9 were strongly expressed in corneal tissue with overwhelming inflammation in day 5 after treatment, however, the expression intensity weakened in 14 days after treatment in the combined treatment,showing significant differences in the absorbance between them (all at P＜0.05).ELISA assay showed that the contents of TNF-α and IL-1β in corneal tissue were significantly lower in the combined treatment group than those in the BSS group (P =0.00,0.03).In addition, contents of TNF-α and IL-1β in corneal tissue were significantly declined at day 14 in comparison with day 5 and day 7 after treatment in the combined treatment group (all at P＜0.05).Conclusions Overwhelming inflammatory keratitis models can be successfully established by corneal intrastromal injection of Pseudomonas aeruginosa suspension and immediately frequent 3-day instillation of gatifloxacin eye drops in rabbits.The topical application of doxycycline plays treating effect on overwhelming inflammatory keratitis by inhibiting the release of pro-inflammatory cytokines and MMPs.
