OBJECTIVETo study the blood enriching effects of Paeoniae Radix Rubra and Paeoniae Radix Alba, paeoniflorin and albiflorin on mouse model of blood deficiency caused by γ-ray radiation.

METHODBuild mouse model of blood deficiency induced by γ-ray radiation. Paeoniae Radix Rubra and Paeoniae Radix Alba were given during modeling. The amount of WBC was detected af- ter the treatment. Based on the result of WBC and paeoniflorin content, albiflorin content in Paeoniae Radix Rubra and Paeoniae Radix Alba, the same model and the same method were used to comparatively study the effect of blood enriching of paeoniflorin and albiflorin.

RESULTOn the 7th day, the amount of WBC in model mice treated with 2 g x kg(-1) Paeoniae Radix Alba and 2 g x kg(-1) Paeoniae Radix Rubra significantly increased compared with that of model group (P < 0.05). In another experiment with the same model, the amount of WBC in model mice treated with 120 mg x kg(-1) paeoflorin and 120 mg x kg(-1) albiflorin significantly increased (P < 0.05) compared with that of model group on the 7th day. On the 10th day, the amount of WBC in rats treated with 120 mg x kg(-1) paeoflorin increased significantly (P < 0.05) compared with that of model group. Compared with the same dose of paeoniflorin, the amount of WBC in mice treated with albiflorin had no significant difference.

CONCLUSIONAll Paeoniae Radix Alba, Paeoniae Radix Rubra, paeoniflorin and al- biflorin can raise the amount of WBC and have the effect of enriching blood induced by radiation, while paeoniflorin and albiflorin have a similar result in this model. The result indicated that both paeoniflorin and albiflorin are effective constituents in Paeoniae Radix Alba, and paeoniflorin work as the common effective constituent in both Paeoniae Radix Rubra and Paeoniae Radix Alba.

OBJECTIVETo study the clinicopathologic features and differential diagnosis of myxoid dermafibrosarcoma protuberans (DFSP).

METHODSThe clinical and pathologic features of 16 cases of myxoid DFSP were reviewed.

RESULTSThere were altogether 15 males and 1 female. The age of the patients ranged from 11 to 73 years (mean = 47 years and median = 48 years). The commonest site of involvement was trunk (number = 11), followed by shoulder (number = 2), head and neck (number = 2), and extremity (number = 1). Similar to conventional DFSP, most patients presented with a slowly enlarging subcutaneous nodule which showed a rapid recent growth in some cases. Amongst the 16 cases studied, 12 occurred de novo and 4 represented local recurrence. The tumors ranged from 2 to 10 cm in greatest dimension (mean = 5 cm and median = 4 cm). Histologically, they were poorly circumscribed and located in the dermis, with focal infiltration into the underlying subcutaneous tissue. Seven cases were purely myxoid and composed of spindly and stellate cells with delicate arborizing vascular meshwork. The remaining 9 cases were predominantly myxoid (> 50%), with 5 cases containing cellular areas resembling conventional DFSP and 4 cases showing fibrosarcomatous transformation. In addition, foci of giant cell fibroblastoma-like areas were noted in 1 case. Immunohistochemical study showed that the tumors cells were positive for CD34. The staining was weak in the myxoid areas, as compared with conventional DFSP. Of the 4 recurrent cases, one patient developed lung metastases.

CONCLUSIONSMyxoid DFSP represents a rare variant of DFSP and may pose important diagnostic pitfalls. It is especially so if the tumor purely consists of myxoid element. Familiarity with the histologic features helps to avoid misdiagnosis.

Objective To determine clinical characteristics and the effects of drug-eluting stents on the occurrence of major adverse cardiac events during percuteneous coronary artery interventional(PCI)and long- term outcomes in patients with chronic renal insufficiency(CRI).Methods Nine hundreds and seventy three patients with angiographically-documented coronary artery disease(lumen inner diameter narrowing＞50%), included 516 patients complicated with experienced renal impairment(CRI group)and 457 with normal renal function(control group).Baseline clinical data and coronary angiographic features were recorded.Results Comparing with control group,patients in CRI group were older with higher incidence of hypertension or diabetes and simultaneously complicated by reduced left ventricular ejection fraction,and more complex coronary lesions(type C).During follow-up(mean 17 months),the mortality was significantly higher in CRI than in control group(6.2% vs 3.3%,P＜0.05),but the former with CRI was significantly lower by using drug-eluting stents in comparing with bare-metal stents(4.1% vs 8.5%,P＜0.05).Conclusion Patients with CRI often complicated with severe coronary artery disease,the mortality after PCI would be significantly reduced by using drug-eluting stents.

Neuroendocrine tumors (NETs) is a rare and heterogeneous group of tumors with widely varying morphologies and behaviors. Due to their rarity and heterogeneity, progress in improving its treatment has been slow. Pancreatic neuroendocrine tumors (pNETs) is a subset of NETs, previously known as islet cell tumors, occupies 3% of the primary pancreatic tumors with the annual incidence rate of (1-2)/100 000. In recent years, it is very necessary to improve the diagnosis and treatment of pNETs.

Metastatic epidural compression of the spinal cord is a significant source of morbidity in patients with systemic cancer. With improvment of oncotheray, survival period in the patients is improving and metastatic cord compression is en- countered increasingly often. Surgical management performed for early circumferential decompression for the spinal cord com- pression with spine instability, and spine reconstruction performed. Patients with radiosensitive tumours without spine instabili- ty, radiotherapy is an effective therapy. Spinal stereotactic radiosurgery and minimally invasive techniques, such as vertebro- plasty and kyphoplasty, percutaneous pedicle screw fixation, radiofrequency ablation are promising options for treatment of cer- tain selected patients with spinal metastases.

Objective To report the clinical and pathological characteristics of one patient with glycogen storage disease Ⅳ (Anderson disease). Methods The patient was received detailed clinical examinations, ultrasound, electromyography, head MRI and muscle biopsy. Results The onset of the 22 years old male patient was 7yrs. The main symptoms were intolerance and fatigue in proximal limbs muscular movement, cardiopalmus by chance. Abdominal ultrasound examinations showed cirrhosis, portal hypertension, splenomegaly. Echocardiogram showed left ventricular myohypertrophia, mild mitral and tricuspid valve insufficiency. Electrophysiology study revealed widespread myogenic changes. Cranial MRI, MRA and MRS were normal. Muscle biopsy showed basophilic intracytoplasmic material in a lot of fibers deposits, which was intensively PAS-positive material and partially resistant to diastase digestion. In the electron microscope, the storage material consisted of filamentous and finely granular material. Conclusions There was the first case of glycogen storage disease Ⅳ reported in our country, mainly involved skeletal muscle, liver, spleen and cardiac muscle.

Objective To explore the value of brain CT scanning for distinguishing tumor-like inflammatory demyelinating diseases (TIDD) from glioma or primary central nervous system lymphoma.Methods The brain CT features in 20 patients with TIDD(10 female,10 male;mean age (35.6±14.0)years;range,6-51 years)and 32 gliomas(16 female,16 male;mean age(42.0±19.8)years;range,12-75 years)and 6 lymphomas(3 female,3 male;mean age(53.8±11.8)years;range,32-68 years)were retrospectively reviewed and compared between brain tumors and TIDD.Results (1)Among the 38 primary brain tumors,there were 19 cases(50%,14 gliomas,5 lymphomas)with hyperdense lesions,10 cases(26.3%,9 gliomas,1 lymphomas)with isodense lesions,and 9 glionms (23.7%)with hypodense lesions.In contrast,the brain unenhanced CT manifestation of 20 TIDD all showed with hypodense lesions.(2)On unenhanced CT the lesions of 6 lymphomas all were hyperdense or isodense,like 90% of 20 high grade gliomas(WHO grade Ⅲ and Ⅳ),but this rate for grade Ⅱ was only 41.7%.(3)According to the shape of hyperdense lesions of the 19 primary brain tumors with,7 cages(6 gliomas,1 lymphomas)manifested with asymmetric hyperdense small-patches,4 cases(1 gliomas,3 lymphomas)with symmetric hyperdense large-patches,4 cases(3 gliomas,1 lymphomas)with diffused hyperdensed lesions,and 4 cases(4 gliomas)with ring-shaped hyperdensed lesions.Furthermore,4 primary brain tumors(4 lymphomas)underwent CT enhanced scanning and all the cases showed strong enhancement(3 cases with hyperdense lesions and 1 with isodense lesions on unenhanced CT),but only 3 cases of 7 TIDD showed mild enhancement in contrast.(4)By Spearman's relevant analysis,hyperdense and isodense on unenhanced CT was proved to have significant positive correlation between the grade of gliomas(r=0.435,P=0.013).Therefore,the frequency of hyperdense and isodense lesions in lymphomas and WHO grade Ⅲ and Ⅳ astrocytoma was higher in contrast with low grade astrocytoma.Conclusions Brain CT as a simple,economical and practical examination method has significant meaning for differentiating TIDD from glioma or PCNSL and could be used as an adjuvant method for MRI and magnetic resonance spectroscopy.Patients with hyperdense or isodense on unenhanced CT or strong enhancement could be excluded from TIDD.
