AIM: To evaluate the clinical outcomes of management in younger patients with primary chronic angle-closure glaucoma (PCACG).METHODS: Thirty-eight patients (50 eyes) aged 40 or younger with confirmed diagnosis of PCACG in advanced or late stage who received surgical treatment in Zhongshan Ophthalmic Center from January 2000 to December 2005were retrospectively investigated. All patients underwent trabeculectomy. The mean follow-up was 23.6±7.5 months.Full ophthalmic examinations were performed. The clinical outcomes including clinical presentations, surgical results and complications were evaluated.RESULTS: The mean age of patients was 33.5±6.1 years old. There was a female preponderance (60.5%). The mean axial length was 22.4±3.5mm with 18.0% short axis of eyeball and 14% nanophthalmos. There was 60.0% fiat anterior chamber depth (<1.9mm). Ultrasonic Biomicroscopy identified that plateau iris was the most common underlying etiology (80.6%). There was a statistically significant difference in intraocular pressure (IOP) reduction postoperativelyvs preoperatively (P<0.001). Four eyes failed to control IOP and received second filtration surgery. The main postoperative complications included shallow anterior chamber (20.0%) and malignant glaucoma (12.0%).CONCLUSION: The younger PCACG patients in advanced or late stage can be effectively managed by trabeculectomy.They have more frequency of postoperative sustained shallow anterior chamber and malignant glaucoma. Careful ophthalmic examinations, delicate surgical procedures and well-managed technique of complications were suggested on younger PCACG patients.

Objective To observe the effects of Baishile Capsules on the hippocampal PI3K signaling pathway in chronic mild unpredictable stress (CUMS) rats; To discuss its mechanism of action for anti-depression. Methods SD rats were randomly divided into 6 groups, control group, model group, fluoxetine group, Baishile Capsules high-, medium- and low-dose groups, with 10 rats in each group. The cums depression model was established, and gavage for medication was conducted at the same time for 21 days in a row. The behavioral changes of rats in each group were detected by the novel feeding experiment and Open-field experiment; monoamine neurotransmitter in serum were detected by ELISA; the expressions of PI3K, AKT and SGK1 in rat hippocampus were detected by immunofluorescence and Western blot test. Results Compared with the control group, feeding latency of rats in model group was significantly prolonged (P<0.01), horizontal and vertical activities were significantly reduced (P<0.01); the content of serum monoamine neurotransmitter decreased (P<0.01); the expressions of PI3K and AKT in hippocampus decreased, while the expression of SGK1 increased (P<0.01, P<0.05). Compared with the model group, Baishile Capsule high- and medium-dose groups can significantly shorten the incubation period of feeding rats (P<0.05), and increase the number of horizontal and vertical activities (P<0.01); the 5-HT and NE levels in serum were significantly elevated (P<0.05, P<0.01); the expressions of PI3K, AKT in hippocampal increased; the expression of SGK1 decreased (P<0.05, P<0.01). Conclusion Baishile Capsules can alleviate the depression like behavior in rat models, and regulate key factors of hippocampal PI3K signaling pathway, so as to exert antidepressant effects.

OBJECTIVETo observe the effect of Bushen Wenyang Huayu Recipe (BWHR) on hypoxia inducible factor-1α (HIF-1α), proline hydroxylase2 (PHD2), von Hippel Lindau disease (VHL) suppressor gene expressions in endometriosis (EM) rats with Shen yang deficiency blood stasis syndrome (SYDBSS), and to explore the pathogenesis of EM and the mechanism of BWHR for treating EM.
METHODSTotally 50 SD rats were randomly divided into five groups, i.e., the blank control group, the sham-operation group, the model group, the Chinese medicine (CM) group, and the Western medicine (WM) group, 10 in each group. Rats in the blank control group and the sham-operation group were fed routinely. Rats in the rest 3 groups received 30-day "extended refrigerator freezing and ice water immersion" and combined with " autotransplantation" to establish EM rat model with SYDBSS. One Milliliter BWHR at 3.33 g/mL was administered to rats in the CM group by gastrogavage. Gestrinone at the daily dose of 0. 5 mg/kg was administered to rats in the WM group by gastrogavage. Equal volume of normal saline was administered to rats in the model group, the blank control group, and the sham-operation group. The size and morphology of ectopic foci in rats were observed after 4 weeks of medication. Expressions of serum CA125, plasma cyclic adenosine monophosphate (cAMP), and plasma cyclic guanosine monophosphate (cGMP) were detected by radioimmunoassay. Morphological changes of eutopic endometrium and ectopic tissue were observed under the optical microscope by HE staining. Protein expressions and contents of HIF-lα, PHD2, and VHL were detected by immunohistochemical SABC method and Western blot. mRNA expressions of HIF-1α, PHD2, and VHL were detected by RT-PCR.
RESULTSThe ectopic foci grew significantly in the model group. Their volumes were obviously contracted after treated by CM and WM. Compared with the blank control group and the sham-operation group, serum CA125 and plasma cGMP obviously increased, cAMP obviously decreased (P < 0.05); expressions and contents of HIF-1α mRNA and protein all decreased (P < 0.05); mRNA and protein expressions and contents of PHD2 and VHL all decreased in the model group (P < 0.05). Compared with model group, levels of CA125 and cGMP obviously decreased; cAMP levels obviously increased, expressions and contents of HIF-1α mRNA and protein all increased, mRNA and protein expressions and contents of PHD2 and VHL all increased in the WM group and the CM group (P < 0.05). Compared with the CM group, PHD2 protein contents were higher in the WM group (P < 0.05). HIF-1α was negatively correlated with PHD2 (r = -0.799, P = 0.00). HIF-1α was negatively correlated with VHL (r = -0. 625, P = 0.003).
CONCLUSIONSBWHR could effectively treat EM. Its mechanism might be associated with reducing contents of HIF-1α, serum CA125, and plasma cGMP, and up-regulating expressions of PHD2, VHL, and cAMP.

OBJECTIVETo investigate the influence of pleiotrophin (PTN) on the growth of rat hepatocytes.
METHODSPrimary rat hepatocytes were isolated from male Sprague-Dawley rats and divided into three groups: group A (negative control), cultivated in normal culture medium; group B (positive control), cultivated with culture medium supplemented with supernatant from the embryonic fibroblast 3T3 cell line; group C (experimental), cultivated with culture medium supplemented with human recombinant (hr) PTN (100 ng/ml). The hepatocytes' growth rate and level of secreted albumin (ALB) were evaluated by microscopy and biochemical assay, respectively. Significance of between-group differences were assessed by one-way ANOVA, and pairwise comparisons were performed by the least significant difference test.
RESULTSThe growth rates of hepatocytes in groups A, B and C were 2.800+/-0.084%, 4.300+/-0.132% and 3.800+/-0.053%, respectively. The growth rate of group B was significantly higher than the other two groups (F = 333.735, P less than 0.05). For all groups, the highest levels of secreted ALB were detected between the second and sixth day of culture, with g/L concentrations at day 2, 4 and 6 of: group A, 0.550+/-0.010, 0.900+/-0.030 and 0.300+/-0.040; group B, 0.900+/-0.030, 1.300+/-0.020 and 1.400+/-0.030; group C, 0.900+/-0.010, 1.160+/-0.010 and 0.700+/-0.050. The secreted ALB of group B was significantly higher than that of the other two groups (F = 651.355, 338.831 and 863.205, P less than 0.05 ).
CONCLUSIONPTN can benefit in vitro culturing of rat hepatocytes by stimulating growth and enhancing their ability to secrete albumin.
