OBJECTIVETo investigate the incidence of depression and its etiological factors in patients with cryptorchidism 6-16 years after surgical treatment.

METHODSUsing Self-Rating Depression Scale and Correlation Factor Questionnaire, we investigated the incidence of depression symptoms among 70 patients with cryptorchidism 6-16 years after surgical treatment and another 70 healthy males as controls, and analyzed the related factors of depression symptoms.

RESULTSThe incidence rate of depression symptoms was 50% in the cryptorchidism patients postoperatively, extremely significantly higher than 4.3% in the control group (χ2 = 23.5, P <0.01). Multiple stepwise regression analysis showed that the main risk factors of depression symptoms were worries about natural fertility (F = 15.8992, P <0.01), dissatisfaction with scrotal appearance (F = 4.6003, P <0.05), and the status of being married (F = 4.1002, P <0.05).

CONCLUSIONSymptoms of depression often occur in cryptorchidism patients after operation, and the major etiological factors are infertility, dissatisfaction with scrotal appearance, and the status of being married.

To observe the effects of total flavones of Metasequoia glyptostroboides Hu et Cheng (TFM) on volume-overload cardiac hypertrophy and the expression of c-Fos protein in rat. Methods　Volume-overload cardiac hypertrophy of rat was induced by aortocaval shunts. The rats were given ig TFM (400, 40 and 4 mg/kg/d). c-Fos protein in the ventricles were measured by immunocytochemical study. Results　TFM at the above dosage decreased heart weight and contents of RNA and protein in the myocardium, inhibited the expression of c-Fos protein in the ventricles. Conclusion　TFM can prevent volume-overload cardiac hypertrophy in rats. The inhibitory effects on the expression of c-Fos protein may be its mechanism in the molecular level.

This study was aimed to clone human intercellular adhesion molecule-1 (ICAM-1) gene, to transfect the constructed eukaryotic expression vector ICAM-1-GFP into CHO cells, as well as to detect ICAM-1-GFP expression in CHO cells binding with Molt-4 cells. ICAM-1 cDNA gene was amplified by RT-PCR and inserted in PMD(18)-T vector. Then ICAM-1 cDNA from pMD18-ICAM-1 vector was subcloned into eukaryotic expression vector pEGFP-C1 to construct recombinant ICAM-1-pEGFP-C1 vector. Restriction analysis and DNA sequencing were used to confirm the recombinant vector. After stable transfection of CHO-K1 cells with the recombinant vector, the expression and subcellular localization of ICAM-1-GFP were detected by RT-PCR, flow cytometry and fluorescence microscopy. The function of ICAM-1-GFP fusion protein was assessed by the binding of ICAM-1-GFP/CHO cells to Molt-4 cells. The results showed that 1622 bp full-length ICAM-1 cDNA obtained and was successfully ligated with pMD(18)-T-vector, subcloned to construct recombinant ICAM-1-pEGFP-C1 vector. Restriction analysis and DNA sequencing indicated that recombinant ICAM-1-GFP was successfully constructed and ICAM-1-GFP was expressed stably in CHO cells. ICAM-1-GFP expression was only observed in the cytoplasm of ICAM-1-GFP/CHO cells by fluorescence microscopy. The ICAM-1-GFP/CHO cells were bound to PMA-treated Molt-4 cells. The expression of MEM-148 was very weak in PMA-treated Molt-4 cells. It is concluded that the ICAM-1-GFP eukaryotic expression vector has been constructed successfully and expresses stably in CHO cells. PMA can increase the binding of Molt-4 cells to ICAM-1-GFP/CHO cells by inducing specialized form of ICAM-1 clustering.

OBJECTIVETo explore the effect of Bushen Huoxue Compound (BHC) on lactate dehydrogenase (LDH) leakage, expressions of vascular endothelial growth factor (VEGF) and VEGF mRNA in retinal Muller cells under high glucose condition or advanced glycosylation end products (AGEs) condition by using serum pharmacological method.

METHODSThe retinal Müller cells of 5-7 days post-natal Sprague Dawley (SD) rats were cultured with modified enzyme-digestion method. Purified retinal Muller cells were cultured in normal conditions, high glucose condition (50 mmol/L) or AGEs (50 mg/L and 100 mg/L) conditions, and BHC-containing serum was added to culture medium. The LDH leakage and VEGF expressions were measured by enzyme-linked immunosorbent assay (ELISA). In addition, the relative expression of VEGF mRNA was tested by reverse transcription polymerase chain reaction (RT-PCR).

RESULTSCompared with the normal control group, expressions of VEGF and VEGF mRNA were significantly increased in the high glucose group, the low dose AGEs group and the high dose AGEs group (all P < 0.01). The LDH leakage was obviously increased in the high dose AGEs group, when compared with the normal control group and the high glucose group (P < 0.01). The LDH leakage, expressions of VEGF and VEGF mRNA were obviously decreased by BHC-containing serum both in high glucose and AGEs conditions (P < 0.05, P < 0.01). BHC-containing serum had no significant effect on the LDH leakage and expressions of VEGF and VEGF mRNA in normal conditions (P > 0.05).

CONCLUSIONSAGEs intervention could obviously lower the stability of Müller cell membrane. Up-regulated expressions of VEGF and VEGF mRNA in cultured Müller cells could be induced by AGEs or high glucose. BHC-containing serum could stabilize the stability of Müller cell membrane, inhibit the transcription of VEGF mRNA and decrease the protein expression of VEGF, which might be one of important mechanisms for preventing and treating diabetic retinopathy.
