Objective To study the clinical,image and pathological features of cerebral gliomatosis.Methods 2 cases with cerebral gliomatosis underwent routine MRI scan, contrast enhance MRI scan and pathologic examination of the lesions. Their clinical manifestations were observed during the past 2 years.Results Main clinic features of the 2 patients were headache, dizziness, nausea, vomit, diplopia, hemiplegia, hemianesthesia and ataxia. Cranial MRI scan showed long T 2 signals in the bitemporal lobes, biparietal lobes, corpus collosum, thalamus, caudate nucleus and putamen. Brain stem and cerebellum were also involved in 1 patient. The borders of the lesions were unclear and no mass-effect phenomenons were found. Contrast enhancement occurred only in 1 patient after Gd-DTPA injection. The biopsies in the 2 patients showed diffuse infiltrative growth of most astroglioma cells. The shape of nucleus was round or ellipse and the staining of nucleus was comparatively deep. Cleavage of nucleus was seldom. The 2 patients died in 4 to 6 months after the onset of the disease.Conclusions MRI scan and pathologic examination are essential diagnostic methods for cerebral gliomatosis. The prognosis of cerebral gliomatosis is poor.

Objective To evaluate the efficiency of Finasteride in treating inflammatory hemospermia and approach the mechanism of action. Methods 56 cases of hemospermia were randomly divided into two groups. The experimental group (n = 30) was treated with Finasteride combined with antibiotic for 1 month, while the control group(n=26) was treated only with antibiotics for 1 month. The expression of VEGF in sperma was de-tected by enzyme linked immunosorbent assay (ELISA) in pretherapy and post-treatment. Results Hemospermia disappeared in 28 cases of experiment group(28/30, 93.3%) and in 17 cases of control group(15/30,57.7%),with significant difference. The expression of VEGF degrade in post-treatment. Conclusions Hemospermia can be treated more effective with finastefide combined with antibiotics. The mechanisms may be associated with Finas-teride can reduce VEGF synthesis and inhibit the microvascular formation.

Objective To report clinical symptoms of a Chinese pedigree of familial paramyotonia congenital (PMC) with progressive myopathy (PM), and investigate the mutations of hot spots in the adult skeletal muscle sodium channel α-subunit (SCN4A). Methods The medical history and clinical phenotype of the patients from this large family with PMC were collected. Insertional and spontaneous activity were recorded by routine electromyograph (EMG), and the exercise test (ET) and cool water test were also performed on some patients during episodes. The mutations of SCN4A were screened by PCR-SSCP and DNA sequencing in affected and unaffected members. Results The family is a four-generation kindred with 15 members affected by severe, homogeneous paralysis periodiea paramyotoniea pheuotype. The onset was early, and almost all patients developed severe progressive myopathy by middle age. Routine EMG shows myotonia discharge in all affected subjects. The compound remarkably motor action potential (CMAP) decreased more than 40% after ET with greater decreases in cool water test than in ET. The mutation screening study revealed a missense mutation (Met1592Val) in SCN4A in patients. Conclusions Autosomal dominant inheritance pattern with complete penetrance was observed in this family. The phenotype is in accord with that reported in other ethnic populations with more severe symptoms. The ET and cool water tests may be used as an easy and reliable diagnostic method. Our research supports that periodic paralysis and paramyotonia can be caused by the same mutation in SCN4A. Mutation Met1592Val is a hotspot for mutation screening in patients with PMC accompanied by PM in the Chinese population.

Objective To discuss the clinical features, diagnosis and therapy of primary adrenal lymphoma (PAL) . Methods Two patients (65-year old and 52-year old respectively) who complained vague pain were analyzed. Occupying lesions in adrenal gland were discovered by computed tomography (CT) and diagnosed by needle biopsy and laparoscopic surgery. Results The two patients in our hospital were diagnosed as nonHodgkin's lymphoma. They were treated with chemotherapy and one of them was partial response. Literatures on PAL were reviewed. In the literature, 7 of the 65 patients achieved complete response, 15 partial response, 43 death or unspecified and the survival duration was 3 days to 26 months. Conclusions Most of PAL are bilateral, without specific clinical characters. Neele biopsy is the first choice to make the diagnosis. The therapeutic modalities for PAL include surgery, chemotherapy, surgery followed by chemotherapy as well as radiation therapy. The prognosis of PAL is poor if other organs are involved.
