The authors examined the Ascaris Eggs on the surface of the strawberries and in the soil of the strawberry yards. The results were as follows : 1. The number of Ascaris eggs detected from 870 strawberries grown on strawberry yards was 26, of which 17 eggs were found to be alive. 2. The mean number of Ascaris eggs detected in every 10gm of the soil of strawberry yards was 10.3. The Ascaris eggs were detected over 93% from th yards examined, which had been fertilized with both chemical fertilizer and night soil, or night soil only. 3. No Ascaris eggs was found from strawberries which were produced only with chemical fertilizer. 4. Ascaris eggs were detected 6 from 705 marketing strawberries studied, 3 of them developed to larval stage. 5. When the strawberries were washed by shaking 20 time after kept immersed in water for 10 minutes, the recovery rates of Ascaris eggs after first, 2nd, 3rd, 4th and 5th washing were 60, 87, 96, 99 ad 100%, respectively. 6. Besides Ascaris eggs of hook worm and Fasciolidae were also found from the strawberries examined.

Objective To establish an evaluation system to assess the effect of personnel training program for health professionals in the hospital,in order to achieve the goal that improve the overall competitiveness of the hospital.Methods Comparing and analyzing the differences in research project,research achievements,personnel capacity building before and after implementation of the training program.Paired T-test was used to exam the differences.Results There are statistically significant differences for proposed analyses (p ≤ 0.05).Conclusions The outcome of this study indicates that the personnel training program is extremely important to further development of the hospital.

Background The dosage of verteporfin photodynamic therapy (PDT) for central exudative chorioretinopathy(CEC) depends on the calculation formula of Treatment of Age-related Macular Degeneration with Photodynamic Therapy Study Group(TAP)and Verteporfin in Photodynamic Therapy Study Group(VIP).Some local adverse responses or normal tissue damage have been noted under the standard dose of verteporfin during the treatment of CEC.So it is necessary to explore an appropriate therapeutic dosage of verteporfin.Objective This clinical study aimed to observe and compare the clinical efficacy and safety of different doses of verteporfin PDT for CEC.Methods Ninety eyes of 90 patients with CEC were enrolled in this study with the approval of the Ethic Commission of Affiliated Second Hospital of Nanchang University.Written informed consent was obtained before PDT.The patients were randomly divided into standard dose group,half dose group and 1/3 dose group.All of the patients received PDT.Standard dose(6 mg/m2),3 mg/m2 or 2 mg/m2 of verteporfin was applied in the three groups respectively,with the laser intensity 50 J/cm2.The patients were followed-up for 3 months.Repeat treating regimen was performed in the same way in the patient with fundus fluorescein leakage after initial PDT.Results The BCVA(logMAR) value was 0.44±0.36 after PDT in the standard dose group.Visual acuity improved in 20 patients (66.67％),stabilized in 8 patients(26.67％)and decreased in 2 patients (6.67％).The BCVA showed a significant difference between the preoperative and postoperative BCVA (t =6.719,P =0.000).CNV disappeared in 19 patients (63.33％),obviously improved in 7 patients (23.33％),partially disappeared in 3 patients (10.00％) and unchanged in 1 patient (3.33％).The central fovea thickness (CFT)value was significantly declined in postoperation compared with preoperation (t =5.758,P =0.000).Eight patients received secondary PDT with the recurrence rate 26.67％.In the half dose group,visual acuity improved in 18 patients(60.00％),stabilized in 11 patients(36.67％)and decreased in 1 patient (3.33％).CNV disappeared in 16 patients (53.33％),obviously improved in 8 patients (26.67％),partially disappeared in 5 patients (16.67％) and unchanged in 1 patient (3.33 ％).Significant difference was seen between the preoperative BCVA and postoperative BCVA(t=8.294,P =0.000).The decrease of C FT was significant in postoperation(t =8.493,P =0.000).Ten patients received secondary treatment with the recurrence rate 33.33％.In 1/3 dose group,visual acuity improved in 8 patients (26.67 ％),stabilized in 12 patients (40.00％),decreased in 10 patient (33.3％).CNV disappeared in 8 patients (26.67％),obviously improved in 8 patients (26.67％),partially disappeared in 6 patients (20.00％) and unchanged in 8 patient (26.67％).There was no significant difference between the preoperative BCVA and postoperative BCVA (t =0.536,P =0.596).The difference between preoperative CFT and postoperative CFT was insignificant(t =0.942,P=0.354).Fourteen patients received secondary PDT and 8 patients received three times with the recurrence rate 73.33％.Conclusions 3 mg/m2 verteporfin PDT for CEC shows a similar clinical efficiency and safety to 6 mg/m2 verteporfin.3 mg/m2 verteporfin PDT can decrease cost,but the effect of 2 mg/m2verteporfin PDT is not satisfacted.

Objective To investigate the function of helper T lymphocyte cell(Th)1/Th2 cytokine in food allergy development.Methods A total 110 Balb/c mice were randomly divided into 2 groups:control group(40 mice)and food allergy group(70 mice).Food allergy animal models were established by ovalbumin,performed by skin prick test;in positive reaction mice,serum specific IgE,IL-4 and IFN-? were measured by enzyme linked immuosorbent assay(ELISA),and intestinal pathology were performed,and the mRNA expressions of IL-10,TGF-? in intestinal were measured by real-time PCR assay.Results In food allergy group,the mRNA expression of IL-10,TGF? in intestinal decreased(P

Most insects including the honeybee cause erythema and edema at the site of a sting in non-allergic individuals. This reaction usually resolves within a few days. However, in certain cases, the persistence of inciting materials in the cutaneous tissue may promote a local inflammatory foreign body reaction. Localized nodular lesions were seen in our two patients and erythemstous patches were present in one patient due to rarely encountered complications induced by retained sting materials. In these cases histopathology showed multiple foci of foreign body granuloma containing yellow refraetile material in the center surrounded by histiocytes and foreign body giant cells. The granulomatous skin lesions in these patients were treated with intralesional injections of triamcinolone acetonide and partial excisions of the nodular masses were performed.

Leiomyomas of vagina and vulva are rare solid tumors, but most common mesenchymal tumors in adult woman. Most of the reported cases have been benign. The tumors were firm, well-defined submucosal masses in a majority of patients. We experienced two cases of vulvar and vaginal leiomyoma, thus it is presented with a brief review of the cases and its literatures.

We describe the case of a 45-year-old woman who had self-regressing livedo reticularis on the lower extremities. Examination of a biopsy specimen from the mottled area revealed myxomatous emboli in the deep dermal arterioles. Echocardiography showed a myxoma in the left atrium. After the tumor was surgically excised, the patient had no further evidence of the disorders during the 3-year period of follow-up. Livedo reticularis caused by an peripheral arterial embolism, which in turn was caused by the tumor fragments in our patient with left atrial myxoma, is considered to be unusual.
