Relaxation and contraction factors influencing penile erection are produced and released by the central and peripheral nerves as well as intracavernosal sinus gap and vascular endothelial cells. Aging, diabetes, cardiovascular disease and spinal cord injury can influence these factors. Further researches of hyperbaric oxygenation (HBO) on the erectile dysfunction (ED) can provide some theoretical evidences for the clinical treatment of ED.

Four diterpenoid alkaloids were isolated from Aeonitum longtounens T. L. Ming grown in Lijiang of Yunnan Province, for the first time. They were identified as foresaconitine, chasmaconitine, delsoline and delcosine by Physical contants and spectral data.

One hundred and thirty-two cases of acute facial paralysis involving the channels and collater als (Group A) were treated with acupoint injection of dexamethasone combined with radiance of TOP. And ninety-three cases treated with acupuncture served as the control (Group B). The results showed that the therapeutic effect in Group A was superior to that in Group B ( P

Objective] To study the impact of outpatient appointment supposed on the management of outpatient department and whole hospital. [Methods] Survey and research the average outpatient registration volume, patients' registration waiting time and the patients' satisfaction monthly during May 2011 to May 2014 when outpatient appointment was applied, and analyze the impact of outpatient appointment supposed on the management of outpatient department and whole hospital by comparing the results 3 years ago(during April 2008 to April 2011) when outpatient appointment was not applied. [Results] The number of patients with an appointment was on the rise, the total number of outpatients increased with the increase of outpatient appointment, and patients' registration waiting time was significantly shortened with higher satisfaction. The difference had statistical significance( P<0.05). [Conclusion] By outpatient appointment services, outpatient management has been optimized, with the increase of outpatients; the hospital benefits grow, and meanwhile the patients' satisfaction is improved.

There is a small amount of liquid in healthy people's abdomen,but excessive liquid in abdomen has been called peritoneal effusion or ascites.Ascites is a common clinical sign.Though many causes can lead to ascites,cirrhosis,malignancy and tuberculosis are more common.According to different causes and physical and chemical properties,ascites can be divided into extravasate and transudate.It is important to distinguish between benign and malignant ascites,but sometimes the differential diagnosis is difficult.In this paper,the characteristics of the ascites,the procedure of diagnosis and treatment are discussed.

Objective To explore the change of peripheral benzodiazepine receptors (PBR) expression in the telencephalon of mice with schistosomiasis. Methods The changes of PBR mRNA in the telencephalon of schistosomiasis mice were observed by the real-time FQ-PCR method. The results were judged with circle number of times (C_T) when the level of amplification exponent achieved detecting liminal value. Results Comparing the experiment group (n=10) with the healthy control (n=10) at the 8th、12th、20th week, the changes of C_T were significant(P

Surface-enhanced laser desorption ionization spectrometry (SELDI),as a new type of proteinchip technique,could easily and quickly acquire the information of proteins in all kinds of body fluid and tissue. It could be used in selecting new tumor markers,early diagnosis and evaluating the risk of tumors. This article introduces the principium of this ProteinChip technique,its application in clinic detection,and the outline of its future.

Objective:To evaluate the feasibility of the 3-D surface reconstruction by multislice spiral CT(MSCT) technique in the diagnosis of impacted teeth in maxilla.Methods:Eighty two cases with impacted teeth in maxilla were examined with volumetric CT scan using MSCT,the dental reconstruction images were obtained with multiplanar reformation technique and 3D-reconstruction technique.Results:Dental surface 3D-reconstruction image could display the shape,location and eruption orientation of the impacted teeth clearly.Conclusion:3-D surface reconstruction by MSCT can provide valuable diagnostic and anatomic information of the impacted teeth in maxilla.

Objective To detect the antimutagenesis of carrot juice and to provide necessary data for the development of fruit-vegetable beverage. Methods Revised rat salmonella mutagenicity test was used, strains had been cultured for 48 hours at a constant temperature of 37 ℃. We counted the anaphysis strains produced in the paper circle, and judged whether there was a antimutagenesis effect according to the difference of the anaphysis strain number between the samples and the dissolvent controls. We also judged the mutagensis effect of the samples based on the anaphysis strains outside the paper circle. Results TA98-TA100 strains were all inside the normal scope, mutagenesis effect of all samples had not been observed. Conclusion Under our laboratory conditions, the inhibition rate of sample Ⅰ,Ⅳ on the induction of N-methy1-N/-nitroso-N-nitrosoguanidine(MNNG) to TA100-S9 and of sample Ⅱ, Ⅲ on the induction of aflatoxin B1( AFB1) to TA+S9 was high, and dose-response effect was obvious, also the inhibition effect of both sample Ⅰ,Ⅱ on the induction of AFB1 and that of sample Ⅰ on the Benzo(a)pyrene (BAP) to TA100+S9 was relatively high, but there was no dose-response effect exist.

Objective To investigate the effect of long-term intraocular retention of domestic perfluorocarbon liquid (PFCL) on morphology and histology of ocular tissues. Methods A total of 18 New-Zealand rabbits were randomly divided into 3 experimental groups, whose left eyes underwent intraocular injection with 0.3, 0.6, and 1.0 ml PFCL, respectively. All of the right eyes of the rabbits were in the control group. The morphological, electrophysiological and histological changes of the ocular tissue were observed 4, 8, and 12 weeks after the injection. Results No clinically significant retinopathy but only mild morphological changes were found in group 1 and 2, while obvious morphological and histological changes were found in group 3. Mild morphological and histological changes were found in all of the rabbits 4-8 weeks after the injection while significant ones were found 8-12 weeks after the injection. The results of electroretinography indicated a statistically significant decline of amplitude of b wave in group 3. Conclusions Long-term intraocular retention of few PFCL may cause mild histological changes but not affect the clinical function. Plentiful PFCL remains in eyes may lead to toxic reaction to the ocular tissue.
