The effective flood storage volume of flood storage and detention area is the real capability of occupying flood, which is a fundamental basis when formulating and optimizing real-time the flood dispatching plan in flood storage and detention area. The dispatch of inland river flood will occupy the flood storage volume of lakes, polders and swales in the flood storage and detention area, reducing the effective flood storage volume. This paper selects the flood storage and detention area of Longsai Lake, Hanbei River as an example, calculates and analyzes the flood storage volume and its variation characteristics of lakes, polders and swales occupied by the inland river flood dispatching at different frequencies as well as the change rule of the effective flood storage volume after dispatching inland river flood and its influence. The results show that: ➀ When there are lakes, polders and swales in a flood storage and detention area, the flood storage volume of lakes occupied by the dispatching of inland river flood is significantly greater than those of polders and swales, and the greater the inland river flood, the greater the difference in flood storage volume occupied between lakes versus polders and swales. When the 5-year to 50-year occurrence flood happens in the inland river of the Longsai Lake flood storage and detention area, the flood storage volume occupied by lakes are 97.9%~98.1% in all dispatching volume. ➁ The reduction of the effective flood storage volume in flood storage and detention area caused by inland river flood dispatching changes with the frequency of inland river flood. The greater the flood in the inland river, the more significant the reduction of effective flood storage volume in flood storage and detention area. When the 50-year occurrence flood happens in the inland river of the Longsai Lake flood storage and detention area, the effective flood storage volume decreases by about 13.5%, and when the 5-year occurrence flood happens, the effective flood storage volume decreases by 7.81%. ➂ When the inland river flood occurs and is likely to encounter the flood of the mainstream, the reduction of effective flood storage volume will influence the flood dispatching plan obviously, and the effective flood storage volume of the flood storage and detention area shall be calculated and determined in real time according to the incoming flow, and the dispatching plan shall be optimized or adjusted, the personnel and property shall be transferred in advance.

Objective Exploring the impact of job demand-oriented training on the core competence and quality of nursing in the radiology department. Methods The 26 nurses from the Department of Radiology at the First Affiliated Hospital of Nanchang University were selected as the research subjects, and the training needs were investigated. The training plan was formulated according to the survey results and job characteristics, and the job demand-oriented training was conducted for one year. The core competence, nursing quality, specialist theory and operational skills of the nurses before and after the training were compared. Results After training, the core competence score, preparation completion rate, puncture success rate, post-training nurse specialized theory, and operational skill scores were significantly higher than those before training (all P <0.05). The contrast leakage rate was significantly lower than that before training (P < 0. 05). Conclusion The implementation of job demand-oriented training will help improve the core competence, specialized theory and operational skills of the radiology nurses and improve the quality of care.

Objective: To observe the effect of acupuncture stimulation of acupoints of the Conception Vessel, Kidney Meridian, Spleen Meridian, and Bladder Meridian on menstrual cycles and duration, and serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estrogen 2 (E(2)) levels in patients with diminished ovarian reserve (DOR)., Methods: A total of 96 patients with DOR of both yin and yang deficiency were randomly divided into medication group and acupuncture group (n = 48 cases in each group). Patients of the medication group were treated by Estradiol Valerate tablets, 2 mg/d on the first 10 days, and Estradiol Cyproterone, 3 mg/d from day 11 to 21, followed by 5 -7 days' rest, and the next therapeutic course, continuously for 6 months. For patients of the acupuncture group, filiform acupuncture needles were separately inserted into every 5 points of the Conceptional Vessel, Kidney, Spleen and Bladder Meridians, manipulated with uniform reinforcing and reducing methods till Deqi, and retained for 40 min. The treatment was conducted once daily for consecutive 10 days in one menstrual cycle, beginning from the 10(th) day on after menstruation, which was repeated for 6 months. The integrative scores (normal = 0, mild=2, moderate=4 and severe=6 points) of menstrual cycle, menstrual duration, amount, color, quality [blood blot or ame- nia, symptoms of traditional Chinese medicine (TCM)] were assessed according to "Guiding Principles for Clinical Trials of New Drugs of Chinese Materia Medica". Serum FSH, LH and E(2) contents were detected by Roche's electrochemical luminescence method., Results: After the treatment, of the two 48 cases in the medication and acupuncture groups, 12 (25.0%) and 20 (4.7) were cured, 11 (22.9 %) and 12 (25.0 %) experienced marked improvement in their symptoms, 20 (41.7%) and 10 (20.8%) were effective, and 5 (10.4%) and 6 (12.5%) failed, with the effective rate being 89.6% and 87.5%, respectively. The integral score of TOM symptoms, menstrual cycle, serum FSH, LH and E2 contents were considerably diminished in both groups after 6 months of treatment (P<0.05), and the TOM symptom score, menstrual cycle, and serum FSH, LH and E2 levels were significantly lower in the acupuncture group than in the medication group 6 months after cease of the treatment (P<0.05), while the menstrual duration in each cycle was notably longer in both groups after the treatment, and evidently longer in the acupuncture group than in the medication group 6 months after cease of the treatment (P<0.05). No significant differences were found between the two groups in the effective rate, score of TOM symptoms, menstrual cycle and duration, and serum FSH, LH and E(2) contents following the treatment (P>0.05)., Conclusion: Acupuncture stimulation of acupoints of the Conception Vessel, Kidney, Spleen, and Bladder Meridians is effective in improving clinical symptoms of DOR patients with deficiency of both yin and yang, and has a longer effect, which may be closely associated with its functions in lowering serum FSH, LH and E(2) levels through regulating the hypothalamic-pituitary-ovarian axis.

Foamy virus can establish lifelong persistent infection in mammal hosts without inducing diseases. Such special characteristic stimulates the interests of researchers. As reported, the accessory protein Bet of foamy virus could regulate the gene expression and infection cycle of foamy virus and take part in the generation of chronic viral infection. And also, Bet might prevent the host cellular defense factor APO-BEC3 from interfering the replication of virus and play a role in maintaining viral persistent infection. In order to elucidate the roles of Bet in the foamy virus replication and infection, this review summarized the research progress of Bet protein reported in recent years.

Objective: To investigate the infection of HEV in Quzhou area of Zhejiang Province., Methods: All sera from blood donors in the central blood bank of Quzhou from April 2006 to April 2007 were used. Anti-HEV IgG and anti-HEV IgM were measured by EIA. RT-PCR was also performed to the samples with positive anti-HEV IgM. Genotype and sequence homology were analyzed after sequencing., Results: The positive ratio of anti-HEV IgG was 40.60%, in which the male infection ratio was higher than the female significantly (43.09% VS 36.09%; chi2=22.6; P < 0.01). The infection ratio was increased with age. The positive ratio of anti-HEV IgM was 0.43%. The positive ratio of anti-HEV IgG and the titers of antibody were higher in the inferior clinical infectors with positive anti-HEV IgM than the negative ones (P < 0.05). Two samples were positive in HEV PCR among 21 samples with positive anti-HEV IgM. The toxemia ratio was 0.4% of all the donors. And the genotype of the two samples with toxemia were both HEV-IV., Conclusion: The HEV infection was correlation with age and sex significantly and the infection occurred in the adults mainly in Quzhou area. HEV toxemia was not infrequency in the blood donors.

Background & Objective: Accurate target localization is the essential requirement in the quality control in fractionated stereotactic radiotherapy (FSRT). This paper is to analyze the magnitude of errors in FSRT for head and neck carcinoma including the errors of CT localization, mechanical isocenter, setup of patients, and CT image., Methods: The stereotactic radiotherapy treatment planning system (SRT-TPS), target simulator and head frame were used to check the errors of target localization during each radiation procedure. Five reference points were set randomly; the CT localization error was measured using the target simulator. Seven different mechanical angles of Gantry/Table were selected; the magnitude of isocentric errors of Philips SL-18 linear accelerator were acquired with films. Setup errors were collected by portal films. The image error possibly from CT image artifact was analyzed after scanning a self-made phantom by CT., Results: The CT localization error was(1.5+/-0.4)mm. The maximal error of the mechanical isocenter was (1.0+/-0.6)mm according to the different mechanical gantry/table angles. The distance error of patient setup was (1.0+/-0.3)mm. The maximal total errors estimate was (2.1+/-0.8)mm., Conclusions: The effect of target localization of every procedure should be taken in account in FSRT, the results of the error analysis can be used to determinate the planning target volume in the treatment.
