The pathogenesis of migraine is not fully understood as yet. Recently, with the development of ultrasonography, some stud-ies indicated that the prevalence of right-to-left shunt (RLS) seemed to be higher in migraine, especially in migraine with aura. The progress in the relationship between migraine and RLS was reviewed.

OBJECTIVE: To provide references for the improvement of drug safety of emergent public health events.METHODS: The characteristics of drug demands in emergent public health events were analyzed to guarantee the characteristics of drug safety so as to explore effective safeguard strategy.RESULTS & CONCLUSIONS: Special system and countermeasure are required to guarantee drug safety of emergent public health events.The strategy includes three aspects,i.e.adequate plan in advance,rapid response and timely consummation after the event.

Objective To evaluate the diagnostic value of spiral CT and all kinds of 3D reconstruction in pulmonary tuberculosis .Methods 145 cases of pulmonary tuberculosis confirmed by clinical study and histopathology were analyzed retrospectively. All cases weregiven to helical scan and different cases were given to different 3D reconstruction (CTVE, MPR and CPR) .Results Spiral CT (HRCTespecially) could find many signs of pulmonary tuberculosis, such as centrilobular distribution nodules, tree-in-bud, cavitations,tuberculous pneumonia, miliary nodules, branchogenic dissemination, endobranchial tuberculosis, lymph node enlargement and calcification. The accuracy of spiral CT in the diagnosis of pulmonary tuberculosis was 96.6%, The accuracy of spiral CT with 3Dreconstruction in the diagnosis of pulmonary tuberculosis was 99.31%.Conclusion Pulmonary tuberculosis can be diagnosed accurately by spiral CT with all kinds of 3D reconstruction.

BACKGROUND:In the treatment of early caries, fluoride can be used for remineralization of white spot lesions. Varnish XT (durable fluoride-releasing coating) and ICON penetration resins are two new materials. Varnish XT as a new type of resin reinforced glass ionomer can be selected as mineralized material. ICON penetration resin is a high-permeability resin with good liquidity that can infiltrate by capilary action into the pores created by enamel demineralization. Low-viscosity resin is used to replace the lost hard tissue due to demineralization and occupy the micropores, so as to fil the region of enamel demineralization and prevent further development of lesions. OBJECTIVE:To study the effects of two minimaly invasive surgical treatment materials, Varnish XT and ICON penetrating resin, on the microhardness of enamel caries white spot. METHODS:Totaly 100 incisors of cows were selected, embedded with ethoxyline resin and polished. The lip side facing down served as the observation side. An area of at least 6 mm×10 mm on the enamel face was exposed, and there were five regions from incisal to dental cervix, A, B, C, D, E. After demineralization liquid for artificial caries, no treatment was adopted in region A, treatment with Varnish XT was for region B, treatment with ICON penetrating resin for region C, treatment with fluoride for region D, and region E was sealed with antacid nail. Surface micro-hardness was detected. RESULTS AND CONCLUSION: After demineralization, surface micro-hardness of regions A, B, C, D decreases remarkably as compared with region E (P < 0.05). Surface micro-hardness of regions B, C, D was higher than that of region A, and ranged as folows: C > B and D for surface micro-hardness with statistical significance (P < 0.05). There was no statistical significance of surface micro-hardness between regions B and D (P > 0.05). ICON resin infiltration, Varnish XT and fluoride have obvious improvement effects on surface micro-hardness, and ICON resin infiltration is superior to Varnish XT and fluoride.

Objective To evaluate spiral CT scanning and CT virtual endoscopy(CTVE) in the clinical diagnosis of gastric carcinoma.Methods Spiral CT scan was performed in 28 patients with pathologically-proved gastric cancer . The CT scan parameters were : collimating width 5 mm , Pitch 1 . The volumetric data were acquired using a spiral CT scanner and transferred to computer workstation . CTVE was performed by navigator smooth function . The results were compared with the findings of fiberoptic endoscopy and/or surgery .Results Spiral CT scan could demonstrate the location ,size,extension of lesions and the relation with organs around .In 28 patients,CT findings included omentum involvement(n=7),pancreatic ivolvement (n=4),hepatic involvement (n=3),lymph node metastasis(n=3). CTVE could clearly demonstrate the three-dimensional image of normal wall stomach and the lesions , size and extension of lesions . The appearances of the inner lesions and normal wall of stomach on CTVE were similar to those on fiberoptic endoscopy and/or surgery . The accuracy in detecting lesion by CTVE was 92.8% in 28 patients . Conclusion CTVE combination with spiral CT scan is of great value in clinical diagnosis of gastric carcinoma .

Clinical features of 2 cases of ectopic ACTH syndrome with manifestation of severe hypercortisonism are described with the aim of exploring effective therapies.

Objective: To study the anticancer and antioxidative effect of selenium and survival time in mice with tumor. Methods: According to body weight, the mice with S180 and ECS tumor(half in male and female) were randomly divided into group NS and group selenium. The inhibitory rate?survival time, serum and liver glutathion peroxidase(GSH-Px)?superoxide dismutase(SOD) and malondialdehyde(MDA) were studied. Results: The inhibitory rates on S180 and ECS in group Se were significantly higher than those of the NS group(P

Objective To summarize and analyze data of solid pseudopapillary tumor of pancreas (SPTP) in China,and investigate its epidemiology,clinical features,diagnosis and treatment.Methods Retrieval of Chinese Medical Current Contents and China Biology Medicine disc by the key words of solid pseudopapillary tumor of the pancreas,papillary cystic tumor of the pancreas,pancreatic papillary epithelial tumor,cystic solid tumor of pancreas and Frantz tumor were performed,and relevant literatures were included.Results A total of 1180 SPTP patients from 117 articles were involved.There were 1054 women and 126 men and the ratio of male to female was 1:8.37.The average age was 29 years old (range 9 ～83 years).Detailed clinical information was available for 1172 cases,and the main clinical manifestations included abdominal discomfort (n=526,44.88％),medical check-up (n=464,39.59％),abdominal mass (n=131,11.18％).Laboratory and imaging tests were non-specific.The tumors size was 1.3～ 30 cm with a mean value of 7.84 cm.Four handreds and seven (36.8％) cases were located in pancreatic head,96 (8.7％)were in pancreas neck and 587 (53.1％) were in the body and tail of pancreas.Eleven handreds and sixteen patients received treatment,and the resection rate was 99.2％ (n =1107).Pathological examination showed that 628(57.0％) cases were benign and 306 (27.8％) were presented as malignant behavior,mainly as infiltrative growth and invasion of the surrounding organs,vessels.Nine handreds and seventy-seven cases were followed up (ranging from 1 month to 13 years),and re-occurrence or metastasis were detected in 42 cases (4.3％) and 24 patients died.Conclusions Solid pseudopapillary tumor of pancreas is a rare pancreatic tumor with low-grade malignant potential,and part of this tumor may present as malignant behavior and it primarily affects young females.No characteristics in clinical manifestations,laboratory and imaging tests are found.Pathological examination can confirm the diagnosis.Surgical resection is the therapy of choice and the prognosis is good.

In order to acquire the information on the changes and improvement after the implementation of National Schistosomiasis Control and Prevention Regulation, a survey was performed. The awareness of schistosomiasis and the regulation, stool management and other related contents were carried out in the rural areas of Jiangsu, Anhui, Jiangxi, Hubei, Hunan, Sichuan and Yunan provinces. The results showed 98.9% of the residents knew about schistosomiasis, 89. 8% knew the regulation, 95. 1% supported the management of drinking water and lavatory, 45.3% used tap water as their ordinary drinking water supply, but there were 47.6% still drank well water, 51.1% used water closet and 40.0% used simple toilet. The work on improving water and sanitary conditions in mountain areas was left behind that in lake areas. It is indicated that there is still a lot we must do to promote the propaganda of the regulation.
