Objective To evaluate the effectiveness of intern doctor training by 360 degree evaluation scale and to provide references for formulating targeted training plan. Methods A 360-degree evaluation scale with 6 subscales(Attendings, Peers, Nurse, Patients, Directors and Students) was employed to measure the status quo of medical education , represented by professional ethics and communication skills, among 129 intern doctors in medical clinical college. Cronbach's alpha was used to evaluate the reliability of the scale,one-way ANOVA was used to compare the difference of score among different scorers,and t test and Mann-Whitney test were employed to compare scores be-tween male group and female group, 5-year class and 8-year class (The significance level was set at P<0.05). Results Cronbach' α coefficients were 0.878, 0.948, 0.914, 0.908, and 0.934 for six sub-scales and 0.964 for the general scale. There were significant differences in evaluation scale scores a-mong differ-ent evaluators(P<0.01). After being adjusted by weight index, the average scores of pro-fessional ethics and communication ability & interpersonal relationship were ( 92 . 52 ± 8 . 09 ) and (93.32±8.67) respectively. No differences was observed between male and female, 5-year class and 8-year class(P>0.05). Conclusions 360 degree evaluation scale has reasonable reliability and it can provide valuable references for future similar survey in China. Meanwhile, intern doctors exhibit rela-tively good performances in professional ethics and communication ability & interpersonal relationship in the present study.

Objective To evaluate the diagnostic role of multi-slice CT(MSCT)angiography for tumors of intra-abdominal testes.Methods MSCT angiography of 5 cases with seminoma of intra-abdominal testes proved by surgery and pathology was analyzed.All patients were male,and the age ranged from 33 to 59 years with the mean of 43.6 years.Results(1)The arterial-supply of tumors completely came from the testicular artery of the same side.The arteries went into tumors from the posterior side.(2)The tumors had comparatively large volume with complete or incomplete amicula.The tumor density of 3 cases was inhomogeneous.The degree of entity augmentation of 5 patients was about 14—25 HU.Conclusion MSCT angiography can reveal the tumor vessel and is essential for the diagnosis of tumors of intra-abdominal testes.

Objective To examine the clinical manifestations and pulmonary radiological features in patients with triphosgene poisoning.Methods Clinical manifestations,laboratory tests and CT scans were analyzed retrospectively in 17 patients with triphosgene poisoning.We focused on the severity,development and repair of pulmonary impairment.Results Plain film and CT scans in five mild cases demonstrated bilateral scattered pulmonary patchy shadows.Of 12 cases with moderate to severe diseases,three showed bilateral multiple pulmonary patchy shadows and nodules with confluence of part of the lesions on plain film and CT scans;bilateral lungs were involved in nine cases with imaging findings of bilateral disseminated pulmonary round or ovary nodules with different size,ill-defined and partly-confluent patchy shadows and thickening of both interlobular septum and the wall of bronchus.Of clinical interests,imaging findings were closely correlated with clinical course and laboratory results.Conclusion Radiological examinations with plain films and CT scans could reveal the severity,evolvement of pulmonary edema in patients with triphosgene poisoning,and these are of clinical benefit in the early management and prognostic evaluation of patients with triphosgene poisoning.

OBJECTIVETo observe the influent of the different components of nourishing kidney herbs on the main items of bone metabolism in osteoporosis rats induced with Dexamethasona(DXM).

METHODModels of three-month old SD female rats with osteoporosis here made by being fed with low calcium diet (containing calcium 0.2%) and distilled water, and injected with DXM 0.1 mg/100 g weight intramuscularly, twice a week. Then the osteoporosis rats were treated with different components of nourishing kidney herbs, and the change of calcium, phosphate, alkaline phosphatase(ALP), calcitonin(CT), PTH, CT/PTH, estrogen(E2), testosterone(T), T/E2 and bone section and bone quantitative morphology in these osteoporosis rats were observed.

RESULTThe total components of nourishing kidney herbs could improve the general condition of osteoporosis rats, decrease PTH, increase CT, estrogen, testosterone, CT/PTH and T/E2. The total components of nourishing kidney herbs could improve osteoporotic state, promote bone formation, and inhibite bone resorption. But no effect of the A, B, C, D components of nourishing kidney herbs on the main items of bone metabolism in osteoporosis rats induced with DXM was found.

CONCLUSIONIt is possible that the purification and separation of these herbs weaken or destroy the integrative effect of nourishing kidney herbs or destroy effective components of nourishing kidney herbs during the process of purification and separation.

Objective To learn the timeliness and reasons for the delay in discovering outbreaks via a dengue fever outbreak in Zhejiang Province,and try to improve our disease monitoring system.Methods Epidemic and clinic data were collected by searching cases and epidemiological investigation,and clinic behavior of cases in dengue fever outbreak were described,then the risk factors involved in the delay in discovering outbreak were analyzed.Results Totally 46 cases were found in this outbreak,among which 36 (78.28％) cases were infected before.The onset date of the first case we found was on July 15 th,57 day before the outbreak confirmation.According to the results,95.65％ of cases see a doctor after their sickness,and the rate of three day hospital visiting was 93.36％ (42/46),among which the rate of three day hospital visiting before pathogen confirmation was 91.67％ (33/36),and there was no statistic significance in diagnostic rate before and after pathogen confirmation(P =1.00).Conclusion Cases in this dengue outbreak presented high and timely outpatient rate.Thus,the delay confirmation of dengue fever outbreak was caused by the low sensitivity of doctors in all levels of hospital.More training on dengue fever diagnosis for doctors should be carried out in the future to control and prevent dengue fever more efficiently.

OBJECTIVETo study the mechanism and clinical effect of using the manipulatin of move, adduction, rotation method for the treatment of shoulder dislocation.

METHODSfrom January 2010 to March 2012,120 patients with shoulder dislocation admitted were randomly divided into treatment group and control group, 60 cases in each group. In the treatment group, there were 31 males and 29 females; In control group, there were 30 males and 30 females. In treatment group, 60 patients create their own "on the move, adduction, rotation manipulative treatment,the other 60 cases in control group used traditional restoration methods in wearing the traction treatment. The efficacy of two methods of treatment of shoulder dislocation were compared on reset process once successfully rate, the patient's level of pain (VAS).

RESULTSIn treatment group, restoration once successfully were in 59 cases, improvement of the pain (VAS) values was 3.76 +/- 1.05, the results were excellent in 57 cases, good in 2, poor in 1,without concurrent fractures and nerve injury, without re-dislocation after 3 months. In control group, restoration once successfully were in 50 cases, improvement of pain (VAS) values was 5.67 +/- 1.15, the results were excellent in 45 cases, good in 7, poor in 8. The reset once successfully rate,improvement of VAS values and clinical effect in treatment group were better than that of control group.

CONCLUSIONOn the move, adduction, rotation method has advantages of more wearing traction with uniform force, work together to focus, saving time and effort, easy and convenient to avoid iatrogenic injury.

OBJECTIVETo investigate the diagnostic value of computerized tomographic angiography (CTA) and magnetic resonance angiography (MRA) for intracranial traumatic aneurysms (TAs).

METHODSCTA and MRA of six patients with intracranial TAs verified by digital subtraction angiography (DSA) and surgery were retrospectively analysed. All patients were examined by nonenhanced computerized tomography (CT) and two by CTA. The source data were reconstructed by volume rendering (VR) and multi-planar reconstruction (MPR) from CTA. Four of them had maximum intensity project (MIP) from MRA.

RESULTSOf the six patients, a total of seven TAs were detected by CTA and MRA examinations. Five cases had only one TA and one case had two TAs. The average diameter was 2.3 cm (1.1-3.3 cm). CTA demonstrated two TAs appeared at the cavernous segment of the internal carotid artery (ICA) and the middle cerebral artery (MCA) respectively. MCA TA was definitely and clearly demonstrated on VR images, whereas VR images failed to depict the cavernous ICA TA, which was detected on MPR images. Two TAs were found irregular saccular shape, irregular margin of parent artery and wide neck on CTA. Four MRA examinations demonstrated five TAs, including the cavernous segment ICA TAs (2 cases), the supraclinoid segment ICA TA (1 case), and the cavernous segment associated with opposite side of the petrosal segment ICA TA (1 case). In a cavernous ICA TA, MRA only revealed aneurysm body, whereas aneurysm neck and distal segment of the parent artery were not revealed. In the remaining cases, MRA clearly depicted aneurysm body and parent artery, whereas the neck was not displayed. ICA TAs showed irregular capsule-like high signal intensity on MRA images. Four TAs exhibited irregular distal segment of the parent artery. TAs at the supraclinoid segment or MCA failed to find fracture signs on nonenhanced CT.

CONCLUSIONSBoth CTA and MRA examinations are the effective non-invasive method of imageology for diagnosing intracranial TAs, while CTA is more eligible for diagnosing TAs after nonenhanced CT has demonstrated skull base fractures.
