Neuroblastoma (NB) is a common malignant solid tumor that occurs during childhood;it has a significant heterogene-ity in clinical symptoms and outcome. NB diagnosis is complicated, and various clinical techniques are often involved in examining im-agery, cellular morphology, immunohistochemical staining, gene and molecule biology, and operation excision scope. Diagnoses are graded based on danger extent, which is indicated by clinical stages and unfavorable prognosis factors. These characteristics are the ba-sis for formulating the corresponding synthetic treatment plan. Limited studies are available on treatment norms for adult cases of NB;such cases are currently diagnosed and treated in accordance with child NB diagnosis and treatment norms. An adult patient diagnosed with NB stage 4 is presented. This patient experienced obvious relief from the symptoms after whole body chemotherapy, with further surgery operation indications. This successful case of multi-disciplinary joint diagnosis and cooperative treatment may provide potential treatment techniques for similar patients.

Methods Study clinical data of eight case with PSM infection in patients with AIDS in our hospital from 1999 were definite diagnosed PSM infection in patients with AIDS. Results (1)Eight patients including five females, at a mean age of 26~53, suffered from the diseases for a period of 1~4 months;(2)The most common clinical presentations include fever, stomatomycosis, lymphadenectasis papular skin lesion, anemia, abdominal pain, hepatomegaly, Plenomegaly, Herpes progenitalis, Subcutaneous nodule, Pleural effusion, bad bone ache. Laboratory examination showed elevated hepatic enzymes,coagulated dysfunction,hemocytopenia. Chest X-ray showed nonspecific include bilateval interstitial or alveolar. (3) Fungus cultured: yeast like cells were found in the culture at 37℃ or in tissues. The fungi outside the host cells were elongated, often curved, Sausage like and with clear cemral septate. When cultured at 25℃,the fungus was mycelia-like and produced a characteristic red Pigment, diffusing into the medium. (4) CD4 cell count was reduced significantly, HIV-RNA was high.(5)Mortality was high. Conclusions Definite diagnosis of disseminated Penicillium marneffei requires culture of the pathogenic fungus from clinical specimens. No specific clinical manifestation for Penicillum marneffei infection was found and Amphotericin B are effective in treating penicillosis marmeffei.

Objective: To evaluate the bioavallability and bioequivalence of rabeprazole sodium enteric-coated pellets capsules. Methods:A randomized crossover design was performed in 32 healthy male volunteers. A single oral dose of 20 mg rabeprazole sodium enteric-coated pellets capsules ( test preparation) or enteric-coated shell capsules ( the reference capsules) was administrated under fed conditions. The wash period was 7 days. The blood samples were collected at different time points. The concentration of rabeprazole in plasma was determined by an LC-MS/MS method. The pharmacokinetic parameters were calculated by DAS 3. 0 software and the bio-equivalence was evaluated. Results:The maln pharmacokinetic parameters of the two formulations were shown as follows:T1/2 of (2. 20 ± 0. 83)h and(1. 951 ± 0. 515)h,Tmax of (3. 88 ± 1. 11)h and(4. 64 ± 1. 504)h,Cmax of (401. 06 ± 170. 75)ng·ml-1 and(394. 63 ± 215.64)ng·ml-1,AUC0→t of (918.42 ±427.39)ng·h·ml-1 and (994.49 ±520.73)ng·h·ml-1, and AUC0→∞ of(937.30 ± 445.13)ng·h·ml-1 and(1 011.69 ±534.77)ng·h·ml-1. The analysis showed that the maln pharmacokinetic parameters of the two formulations had no significant differences(P>0. 05) except for Tmax(P<0. 05). The relative bioavallability of rabeprazole sodium enteric-coated pellets capsules was (99. 80 ± 7. 20) %. Conclusion:Compared with the reference capsules, rabeprazole sodium enter-ic-coated pellets capsules show the property of higher dispersion degree, milder influence from food, more rapid release and absorption. The enteric-coated pellets capsules and the reference capsules are bioequivalence.
