OBJECTIVETo investigate the precise locations of the blood vessels and nerves surrounding the seminal vesicles (SV) in men and provide some anatomical evidence for SV-related minimally invasive surgery.

METHODSWe observed the courses and distribution of the blood vessels and nerves surrounding SVs and obtained the data for positioning the SV neuroplexes in 20 male pelvises.

RESULTSOne branch of the neuroplexes was distributed to the SVs bilaterally with the neurovascular bundles, (2.85 ± 0.18) cm from the median sulcus of the prostate (MSP), while another branch ran through the Denonvillier fascia behind the SV, (0.81 ± 0.06) cm from the MSP. The arterial SVs (ASV) originated from the inferior vesical artery and fell into 4 types, 55% going directly to the SVs as one branch, 15% running between the SV and the ampulla of the deferent duct as another branch, 25% downward as 2 branches to the SV and between the SV and the ampulla of the deferent duct respectively, and 5% as the other ASVs. The shortest distance from the ASV through the prostatic neuroplexus to the posterior SV was (1.08 ± 0.09) cm.

CONCLUSIONIn SV resection, neuroplexus injury can be reduced with a bilateral distance of < 2.85 cm and a posterior distance of < 0.81 cm from the MSP, and so can bleeding by vascular ligation between the SV and the ampulla of the deferent duct.

AIM: To investigate the use of therapy ultrasound to enhance nonviral gene delivery. METHODS: Endothelial cells (EC) and vascular smooth muscle cells (VSMC) were cultured in 6-well plates. Plasmid (pcDNA3.1/His/LacZ) with or without microbubbles at the different concentrations was transfected into the cells with the use of ultrasound for 1 min at 2 MHz, 1.8 mechanical index (MI). Additional controls included ultrasound alone, microbubble alone and microbubble plus plasmid. The rate of blue cells and the activities of ?-Gal were measured. In addition, cell viability was detected with different time from 1 to 30 min of ultrasound irradiation and the different concentrations of microbubbles. RESULTS: In the group of ultrasound with microbubble, the rate of blue cells and activity of ?-Gal markedly increased by 60% and 9-fold, respectively. Microbubbles at concentration of 10% led to the highest transfection effect. Ultrasoud exposure at 1 to 30 minute had no cell toxic effects, while microbubbles at the concentration of 50% had significant effect on cell survival. CONCLUSIONS: Albumin-coated microbubbles markedly enhance gene delivery by therapeutic ultrasound-mediated microbubble destruction, which can be used as a safe and practicality vectors in gene therapy.

OBJECTIVETo investigate the tongue manifestation features of sexually transmitted and intravenous drug use spread HIV infected population in Xinjiang.

METHODSRecruited were 990 HIV infected subjects in Xinjiang from May 2011 to March 2012, who were assigned to the intravenous drug use spread HIV infected (498 cases) and the sexually transmitted (492 cases). By using tongue figure shoot combined with analyses of experts, tongue manifestations were analyzed and compared between the sexually transmitted and the intravenous drug use spread from four aspects, i.e., the tongue color, the tongue shape, the fur color, and the fur property.

RESULTSCompared with the sexually transmitted population, red tongue, fissured tongue, yellow fur, thick fur, eroded fur, deficiency of fur fluid were more often seen, showing statistical difference (P < 0.05). Compared with the intravenous drug use spread population, pale tongue, white fur, and thin fur were more often seen, showing statistical difference (P < 0.05).

CONCLUSIONSThe tongue manifestations of the intravenous drug use spread HIV population reflected inner exuberance of evil toxin and heat impairing qi and yin. Compared with the intravenous drug use spread population, the attack of HIV infection was more hiding in the sexually transmitted population, with milder internal injury. Their Wei-qi was not damaged and no obvious change occurred in the tongue figure.

Objective To explore the satisfaction of nurses on the work and patients on the nursing service after implementing the model of continuous scheduling and group-responsibility system,so as to to provide theories for improving nursing quality and human management.Methods Self-designed satisfaction questionaire was used to investigate nurses and patients before and after implementing the model of continuous scheduling and group-responsibility system,and nurses'satisfaction on the work and patients'satisfaction on the nursing care were observed and compared.Results The comprehensive satisfaction of nurses on the work in sixth,ninth,twelfth month after implementing the model of continuous scheduling and group-responsibility system was 91.0％,91.6％,92.3％,respectively which was higher than 80.6％ before implementing,and the difference was statistically significant ( x2 =4.74,5.56,6.40,respectively ; P ＜ 0.05 ).The satisfaction of patients on nursing increased from 90.1％ to 95.7％ after the model was implemented three to twelve months,which was significantly higher than 78.5％ before implementing( P ＜ 0.01 ).Night shift period was shortened and the nurses' satisfaction was decreased from 76.2％ to 61.8％ after the model was implemented ( x2 =6.95,P ＜ 0.01 ),while there was no difference in the situation of their mental pressure.Conclusions The scheduling revolution and group-responsibility system can provide no-gap and excellent nursing,and stimulate nurses' potential,and improve the nursing quality.But the situation of nurses' mental pressure is not improved for the lack of clinical nurses.

OBJECTIVETo review the effects of the active components of Chinese herbs on drug metabolizing-enzymes.

METHODRelevant research papers reported in recent years were consulted and studied.

RESULTThe drug metabolizing-enzymes cytochrome P450 and UDP-glucuronosyl transferase and glutathione S-transferase were inhibited or induced by the flavonoids, furocoumarins, and the active components extracted from salvia miltiorrhiza and hypericum perforatum, and so on, which therefore slowed or sped metabolism of other drugs in vivo and in vitro.

CONCLUSIONMuch attention should be paid to the metabolic interaction of the Chinese herbs when coadministered with other drugs.

BACKGROUNDTo study the relationship of Epstein-Barr virus (EBV) and T cell lymphoma.

METHODSSixty cases of T cell lymphomas were examined for the presence of EBV using in situ hybridization for EBV encoded RNA (EBERs).

RESULTSEBERs were detected in tumor cells in 37(69.8%) of 53 cases with peripheral T cell lymphoma, but in none of seven cases of precursor T lymphoblastic lymphoma. The total detected EBERs were 37(61.6%) in 60 cases of T cell lymphomas. By Revised European-American Lymphoma(REAL) classification, EBERs were detected in 2/2 angioimmuno-blastic T cell lymphoma,17/18 angiocentric lymphoma, 4/6 anaplastic large cell lymphoma and 14/27 peripheral T cell lymphoma, unspecified (51.9%). The frequency of EBERs among the extranodal peripheral T cell lymphoma was higher than the nodal (P less than 0.01) there was no significant correlation with the sex, age and clinical stage.

CONCLUSIONSThis study indicated that high incidence of EBV was observed in peripheral T cell lymphoma, with predilection for angiocentric lymphoma and extranodal presentation.

OBJECTIVETo analyze the influence of knowledge about hypertension and clinical competence among physicians in district and community hospitals on management of hypertensives.

METHODSQuestionnaire investigation was used in 9 district and community hospitals in Chaoyang and Haidian district, including 181 physicians and 204 patients with hypertension.

RESULTS(1) The hospitals involved were divided into two groups according to our evaluation on the knowledge of hypertension and clinical competence of physicians. Four hospitals were graded as high-score group and 5 hospitals as low-score group. (2) There was no significant difference on physicians' evaluation between district and community hospitals. There was higher proportion of hypertensives with instructed physical exercises, reducing salt ingestion, psychological balance and weight reduction in district hospitals than those in community ones. (3) The proportion of hypertensives who were examined with funduscopy, ambulatory pressure and instructed with physical exercises, reducing salt ingestion and weight reduction in high-score group was obviously higher than that in low-score group. The control rates of blood pressure, on the days of examination during lastest check-up or the past three months, were significantly higher in high-score group than in low-score group (P < 0.05).

CONCLUSIONKnowledge of hypertension and clinical management competence among physicians in district and community hospitals did influence the management of hypertension and education of physicians and thus should be increased.
