This review summarizes the present advance of effects of stress on hippocampal structure and function and the role of hippocampus in feedback regulation of thalamic-pituitary-adrenocortical (HPA) axis during stress. It shows that stress can affect hippocampal structure and function, on the other hand, the hippocampus can also suppress the stress reaction through the feedback regulation of HPA axis, but chronic stress can attenuate this regulation, then significantly impair its structure and function.

OBJECTIVETo observe the effects of local co-transfection vascular endothelial growth factor165 (VEGF165) and tissue-type plasminogen activator genes on inhibiting intimal hyperplasia and restenosis in rabbits artery after operation injury and possible mechanisms.

METHODSMicrology operation injury was used to establish the model of intimal injury of right external iliac artery in rabbits. To select 120 male New Zealand rabbits and were randomly divided into 3 groups (n = 40, in each group): Group A (physiological brine control group), Group B (pBudCE4.1 group), Group C (pBudCE4.1/VEGF165-tPA group). The vas-wall of micrology operation injury were infused respectively physiological brine, pBudCE4.1 and pBudCE4.1/VEGF165-tPA transfection solution by micro-injector. Each group were divided into 5 subgroups (n = 8, in each subgroup) randomly according to the sacrifice times (2 d, 1 week, 2 week, 4 week and 8 week after operation). The injured vascular specimen were harvested for pathology test, electric microscopy study, reverse transcription-PCR examining and immunochemistry detecting.

RESULTSThe intimal area and narrow ratio of vases in Group C at every time point after operation were significantly lessened than that in Group A and Group B (P < 0.01). The narrow ratio of vases in Group C at 8 week after operation were decreased respectively by 57.9% and 59.0% than that in Group A and B. The expression of VEGF165 mRNA in Group C were increased significantly than that in Group A and B at every time point after operation (P < 0.01), the expression reached the peak at 1 week and continued to 4 week after operation. Immunohistochemical identified that tPA positive cell in Group C were significantly increased than that in Group A and B (P < 0.01) at every time point after operation.

CONCLUSIONLocal co-transfection VEGF165 and tPA genes could restrain intimal hyperplasia and restenosis of vas, which lay a foundation for future multi-gene therapy of vascular intimal hyperplasia.

OBJECTIVETo discuss the anti-inflammatory mechanism of sinomenine on inflammatory media in joint of adjuvant arthritis rats.

METHODRats were randomly divided into the normal group and the model group, the prednisone group, the small, medium, large of sinomenine group (30, 60, 120 mg x kg(-1)). Except for the rats in the normal group, animals were modeled to adjuvant arthritiswith freund's complete adjuvant. The arthritis index (AI) and the swelling degree of paws were recorded, and the activity of IL-1, TNF and the levels of NO, PGE2 in joint fluids of secondary arthritis were determined.

RESULTCompared with the normal group, the activity of IL-1, TNF and the levels of NO, PGE2 in joint fluids of secondary arthritis were increased significantly in the model group (P < 0.05). Compared with the model group, it was shown to exert a dramatic inhibitory effect on secondary reaction of freund's adjuvant arthritis of rats, and the activity of IL-1, TNF and the levels of NO, PGE2 in joint fluids of secondary arthritis were significantly decreased in the sinomenine group (P < 0.05).

CONCLUSIONSinomenine has a remarkable treatment effect on RA. It is via NO to inhibit the activity of cytokines and decrease the level of inflammation mediators, which may be one of its curing RA mechanism.

OBJECTIVETo investigate the effects of the reconstruction of the mentum with cervical tissue flaps in the surgical management of postburn cervical scar contracture.

METHODSThirteen postburn patients with severe cervical scar contracture and mental deformity were enrolled in the study. The platysma flap (3 cases), scar tissue flap (6 cases) and cervical deep fascia tissue flap (3 cases), with the pedicle containing the facial and the superior thyroidal artery, were turned upwards to replenish mental soft tissue, and to form new mentum and sulcus mentolabialis. The cervical scars were repaired with expanded flap (11 cases), free flap (1 case) or trapezius muscular flap.

RESULTSThe post-operative cervical configuration was found to be good, and the tissue flaps for mental reconstruction healed satisfactorily. Ten patients were followed-up for 6 to 24 months. All flaps were successful and achieved good results, except that scar formation was found in the cervical linear incision in 4 patients.

CONCLUSIONTransfer of the platysma flaps, scar tissue flaps, or deep cervical fascial flaps for the reconstruction of cervical scar were simple and effective. The use of cervical scar tissue flaps could not only loose the constructed scar, but also beneficial in rectifying the configuration of the chin.

OBJECTIVETo assess the clinical effect and safety of the Chinese medicine Longbishu Capsule combined with mesylate doxazosin in the treatment of benign prostatic hyperplasia (BPH) of the kidney deficiency and blood stagnation type.

METHODSThis was a randomized, double-blind, double-simulation control study. We equally assigned 60 men diagnosed with BPH of the kidney deficiency and blood stagnation type to an experimental and a control group, the former treated with mesylate doxazosin plus Longbishu Capsule and the latter with mesylate doxazosin plus placebo. We compared the International Prostate Symptom Score (IPSS), quality of life (QOL), Chinese symptom score (CSS), maximal urinary flow rate (Qmax), and prostate volume between the two groups of patients before and after 6 months of medication.

RESULTSAfter treatment, there were 5 cured cases, 13 markedly effective cases, 9 effective cases, 1 ineffective case, and 2 eliminated cases in the experimental group, as compared with 2 cured cases, 8 markedly effective cases, 10 effective cases, 7 ineffective cases, and 3 eliminated cases in the control group. The total effectiveness rate was obviously higher in the former (96.4%) than in the latter (74.1%). IPSS, Qmax, and CSS were improved in both of the groups after medication, even more significantly in the experimental than in the control group (IPSS: 15.22 ± 2.98 vs 18.15 ± 5.88, P <0.05; Qmax: [13.56 ± 2.26] ml/s vs [11.78 ± 2.97] ml/s, P <0.05; CSS: 6.18 ± 2.13 vs 9.52 ± 3.15, P <0.05). Because of the difference in the QOL score between the two groups at the baseline (P = 0.038 <0.05), no more comparison was made in this aspect after treatment.

CONCLUSIONThe combination of Longbishu Capsule with mesylate doxazosin is safe and effective for the treatment of BPH.

AIMTo investigate the penetration kinetics of xanthotoxin in human skin and stratum corneum.

METHODSThe penetration experiments were accomplished by the deposit of ethanolic xanthotoxin solution onto human skin and stratum corneum mounted on Franz cells. The diffused xanthotoxin in the receptor solution (1.4% human serum albumin) and the retained amount in the skin and in the stratum corneum after 24 h exposure were quantified by using high performance liquid chromatography.

RESULTSXanthotoxin flux was increased with the concentration deposited onto the human skin, and when the concentration is above 2.5 mg x mL(-1), there is no influence on the xanthotoxin flux. Similar results were obtained from the stratum corneum. And the peak time for the flux in the stratum corneum was preceded about 6 h earlier than that of the whole human skin. The retained xanthotoxin amount after 24 h exposure in the skin and in the stratum corneum increased according to the concentration deposited and has the tendency to saturate. The lag time of ethanolic xanthotoxin solution in the whole human skin is significantly higher than that in the stratum corneum (P < 0.05).

CONCLUSIONThe characteristics of penetration kinetics of xanthotoxin will provide the information for concentration choice of topical formulation and give a reference for ultra violet A (UVA) irradiation time confirmation.

OBJECTIVETo investigate the correlation of International Prostate Symptom Score (IPSS) with the levels of interleukin-8 (IL-8) and cyclooxygenase-2 (COX-2) in the prostate tissue and expressed prostatic secretion (EPS) in patients with benign prostatic hyperplasia (BPH) complicated by prostatitis.

METHODSWe divided 80 BPH patients to be treated by transurethral resection of the prostate (TURP) into a simple BPH group (n = 30) and a BPH with prostatitis group (n = 50) based on the pathologic features. We statistically analyzed IPSS and the levels of IL-8 and COX-2 in EPS before surgery and the IL-8 and COX-2 levels in the prostate tissue after surgery.

RESULTSIPSS was positively correlated with the IL-8 and COX-2 levels in the prostate tissue and EPS of the BPH patients, moderately in the simple hyperplasia group (r > 0.5) and highly in the other (r > 0.8). The levels of IL-8 and COX-2 in the prostate tissue and EPS were significantly higher in the BPH with prostatitis group than in the simple BPH group (P < 0.05).

CONCLUSIONThe levels of IL-8 and COX-2 in EPS indirectly reflect those in the prostate tissue. IPSS and the levels of IL-8 and COX-2 in EPS can help determine whether BPH is complicated by histological prostatic inflammation.
