Glaucoma is a group of diseases which can threaten and damage the optic nerve and its visual pathway, leading to visual impairment as a result. Glaucomatous optic neuropathy is a chronic disease accompanied by apoptosis of retinal ganglion cells ( RGCs ) , visual field defect and cupping of optic nerve head. The gold standard in functional glaucoma evaluation is standard automated perimetry ( SAP) , but it is often limited to the subjective feelings of the patients. Still, visual electrophysiological techniques cannot replace the conventional inspection, but with its rapid development, it has provided a new strategy for the early diagnosis of glaucoma as a supplement because it can show changes in amplitude and latency before visual field defect. Here we review three special electroretinograms and multifocal focal visually evoked potentials in the early diagnosis of glaucoma.

The major objective was to explore the effect of early hyperbaric oxygen (HBO) therapy on the tissue structure, apoptosis, and metalloproteinases of kidney cells in Goto-Kakizaki (GK) rats with type 2 diabetes mellitus. GK rats (n = 24) were divided randomly and evenly into model, metformin hydrochloride (MH), and hyperbaric oxygen (HBO) groups, while healthy Wistar rats (n = 8) were used as normal control group. The healthy rats in the normal control group and the GK rats in the model group were both intragastrically administered with purified water (5 mL/kg) once per day. Meanwhile, the rats in the MH group received intragastric administration of MH (250 mg/kg) once daily, while the rats in the HBO group inhaled pure oxygen under a constant pressure (0.15 MPa) for 30 min. After 3 weeks of treatment, the body weight of each rat was measured, and the blood samples were collected from tails. Subsequently, the kidneys of all rats were excised for weighing mass and further examination. For each renal sample, the sections were firstly embedded with paraffin and sliced to prepare histopathologic sections stained using HE, PAS and Masson, respectively, for subsequent observation with optical microscopy. Later, the apoptosis of kidney cells was examined using the TUNEL method by computing the apoptotic index. Furthermore, the histopathologic sections were also examined using the immunohistochemistry approach with Caspase-3, MMP-2, and TIMP-2 antibodies, respectively. At the same time, the plasma concentration of TGF-β1 of the rats in each group was detected using ELISA method. These resultant data showed that the pathological changes of the HBO group were less than those of the model group with respect to increased glomerular volume density of mesangial cells, broadening mesangial matrix and thickening basement membrane as well as swelling renal tubular epithelial cells. The index of cell apoptosis and Caspase-3 expression in the HBO group showed no significant differences (P > 0.05) compared with those in the normal control and MH groups respectively, but demonstrated significant decrease compared with that in the model group (P < 0.01). Meanwhile, the MMP-2 and TIMP-2 expressions of the HBO group were stronger than those in the model and MH groups, but weaker than those in the normal control group (P < 0.05). Although the plasma concentration of TGF-β1 in HBO, MH and model groups was greater than that in the normal control group, no significant statistical difference was distinguished among these four groups (P > 0.05). These results indicate that the HBO treatment can inhibit the apoptosis and Caspase-3 expression of renal cells of GK rats, adjust the activity of MMP-2 and its inhibitors, and reduce the accumulation of extracellular matrix. This implies that the HBO treatment might protect renal tissues, thus delaying occurrence and retaining development of diabetic nephropathy.

OBJECTIVETo study the difference of plasma actual bicarbonate between the children with growth hormone deficiency (GHD) and idopathatic short stature (ISS) and to value the plasma bicarbonate standard deviation scores (SDS) in diagnosis of GHD.

METHODSForty-seven short stature children were divided into two groups (GHD and ISS) according to the peak GH response to provocative test. Plasma actual bicarbonate concentrations anion gap (AG), base excess and electrolytes were measured in 47 children with short stature before GH provocative tests.

RESULTSThe mean plasma actual bicarbonate concentrations, bicarbonate SDS were (22.60+/-1.29)mmol/L and -0.27+/-0.98 respectively in GHD children, which were significantly lower than those of ISS children (P<0.01), whereas AG was higher than that of ISS children [(11.73+/-4.52 vs 7.87+/-1.70) mmol/L], P<0.01. Seventy-two percent of patients with bicarbonate SDS

CONCLUSIONPlasma actual bicarbonate concentrations and bicarbonate SDS are lower in patients with GHD than those in patients with idopathatic short stature. Evaluation of plasma bicarbonate SDS of short stature children can predict the probability of GHD, especially when bicarbonate SDS is less than 1 s.

To evaluate the effects of p-octyl polyethylene glycol phenyl ether (Triton X-100), polyoxyl 35 caster oil (EL35) and polyoxyl 40 hydrogenated caster oil (RH40) on the activity of Cytochrome P450 3A (CYP3 As) in vivo. Rats were administered with saline, ketoconazole (75 mg x kg(-1) x d(-1)), Triton X-100 (30 mg x kg(-1) x d(-1)), EL35 (150 mg x kg(-1) x d(-1)) and RH40 (150 mg x kg(-1) x d(-1)) intragastrically for 5 consecutive days, and then given midazolam 10 mg x kg(-1) 20 min after the last treatment of ketoconazole or three surfactants with the same dose through duodenal administration. Pharmacokinetics parameters for midazolam and its metabolite 1'-hydroxymidazolam were estimated from the plasma concentration-time data by a noncompartmental approach. The results showed that multiple dose administration of Triton X-100, EL35 and RH40 decreased the ratios of 1'-hydroxymidazolam and midazolam AUC0-infinity from 1.14 to 0.90, 1.03 and 0.64, respectively. In contrast, multiple dose administration of ketoconazole caused the ratios of 1'-hydroxymidazolam and midazolam a significant decrease to 0.50. This study indicated that Triton X-100 and EL35 would have no inhibition on CYP3A, while RH40 had significant inhibition on CYP3A. Therefore, RH40 might be used to prepare drug formulations in pharmaceutical industry and would increase the bioavailability of some drugs transformed by CYP3As and further lead to significant clinical pharmacologic effects.

AIM To study the influence and action mechanism of effective components in compatible solution of Sparganii Rhizoma-Curcumae Rhizoma on pelvic adhesions of model rats with chronic pelvic inflammatory disease.METHODS Laboratory rats were randomly assigned into six groups,a sham-operated group,a model group,a positive Fukeqianjin tablets group,compatible solution groups (40 g/kg high-dose group,20 g/kg medi um-dose group,and 10 g/kg low-dose group).Except rats of the sham-operated group,those in the other groups were induced into models of chronic pelvic inflammatory disease by mechanical bacterial strain implantation,after which a 20 d corresponding drug administration by oral gavage for each group was initiated.After completion of the last drug administration,Verco criterion was taken as the reference to evaluate pelvic adhesions,HE staining was performed on uterine tissues for pathological scoring,ELASA method was applied to measuring serum IL-1β and TNF-α levels,and Western blot method was used to detect the expression levels of proteins FGF-2 and IGF-1 in uterine tissues.RESULTS Compared with the model group,the high-dose compatible solution group had a much sharper fall in Verco scores (P ＜ 0.05),and remarkably decreased serum IL-1β and TNF-α levels (P ＜ 0.01);both high-dose and medium-dose groups manifested with notably alleviated degenerative necrosis and lowered scores of chronic inflammation infiltration and epithelial hyperproliferation (P ＜ 0.01 or P ＜ 0.05),and a distinct reduction in the expression of proteins FGF-2 and IGF-1 (P ＜ 0.05,P ＜ 0.01).CONCLUSION The significant improvement of the chronic pelvic inflammatory disease in model rats due to the effective components in the compatibile solution of Sparganii Rhizoma-Curcumae Rhizoma may be associated with inhibited release of inflammatory mediators IL-1β and TNF-α,and the reduced expression of proteins FGF-2 and IGF-1 as well.

Objective To understand the obsessive-compulsive symptoms (OCS) and relative influencing factors among college students with left-behind experience. Methods College students with left-behind experience were selected from three universities in Anhui Province. The Chinese Obsessive-Compulsive Inventory-Revised (OCI-R), Rosenberg Self-Esteem Scale (RSES), Self-Rating Depression Scale (SDS) and self-edited basic situation questionnaires were used to measure the OCS, self-esteem, depression and left-behind experience. Multivariate logistic regressions model was applied to examine the influential factors of OCS. Results A total of 2 291 college students with left-behind experience were investigated. The detection rate for OCS in college students with left-behind experience were 26.5%. Regarding the OCS in college students with left-behind experience, significant differences were found in the following aspects: frequency of meeting with parents, parenting style, conflicts with caregivers, smoking and drinking (all P<0.05). Logistic regression analysis showed that caregiver adopts strict parenting style (OR=1.300, 95%CI:1.025-1.649,P=0.030), indulgent parenting style (OR=1.372, 95%CI:1.017-1.852, P=0.038), smoking (OR=1.982, 95%CI:1.305-3.011, P=0.001), depressive symptoms (OR=2.423, 95%CI:1.954-3.005, P<0.001), medium self-esteem (OR=0.604, 95%CI:0.481-0.759, P<0.001) and high self-esteem (OR=0.488, 95%CI:0.362-0.659, P<0.001) were influencing factors of OCS. Conclusions The prevalence rate of OCS among college students with left-behind experience is high. Some interventions should be taken to reduce the OCS among college students with left-behind experience.
