Some grain sprouts herbs recorded in Chinese Pharmacopoeia 2010, including Oryzae Fructus Germinatus, Setariae Fructus Germinatus and Hordei Fructus Germinatus, together with their adulterants, were identified by ITS2 sequences. The genomic DNA were extracted, their ITS2 sequences were amplified, and purified PCR products were
sequenced. Sequences were assembled using the CodonCode Aligner. The genetic distances, variable sites and the neighbor-joining (NJ) phylogenetic tree were computed by MEGA 6.0 in accordance with the Kimura 2-Parameter (K2P) model. The results showed that their intraspecific genetic distances were all much lower than the interspecific ones of themselves and their adulterants. The NJ tree based on ITS2 sequence indicated that Oryza sativa, Setariaitalica, and Hordeum vulgar formed one monophyletic clade respectively, in addition any one of the grain sprouts herbs and its adulterants could be distinguished clearly. Therefore, ITS2 sequence is suitable to be as a barcode to identify the grain sprouts herbs and their adulterants.

Flow cytometry was previously applied for analysis of Rh(D) antigen density, therefore it was suggested that the flow cytometry may be used for routine detection of weak D positive phenotypes. This study was purposed to evaluate its practicability. Six weak D positive and 7 DEL individuals were detected by using saline, IAT and absorption/elution test from 2010 to 2011 years. By RHD genotyping, zygosity analysis and sequencing, 3 cases of weak D type 15, 3 cases of partial D type DVI-III and 7 cases of DEL carrying RHD1227A alleles were identified. Taking 2 normal Rh(D)-positive and 2 D-negative samples as controls, all the samples were tested by using flow cytometry, and the median fluorescence intensities were observed as well. The results indicated that all weak D type 15 and partial D type DVI samples were detected to be positive by flow cytometry, as compared with 2 Rh(D)-negative samples (P < 0.05). Seven 7 DEL samples were tested to be negative (P > 0.05), although one of 7 DEL was tested as "±" in IAT and strong positive in absorption/elution. The RHD zygosity analysis showed this DEL individual as RHD(+)/RHD(+) homozygote. It is concluded that the sensitivity of detecting D antigen by flow cytometry is similar to that of IAT, but lower than absorption/elution test. As for detecting weak D or partial D antigens, IAT is easier than flow cytometry; as for identifying DEL, the flow cytometry is not sensitive enough.

OBJECTIVETo study the clinicopathologic features, immunophenotype and differential diagnosis of angiomatoid fibrous histiocytoma (AFH).

METHODSThe clinicopathologic features of 5 cases of AFH were analyzed. Immunohistochemical study was carried out and the literature was reviewed.

RESULTSThere were a total of 3 males and 2 females. The average age of patients was 21.4 years old. The average duration of symptoms was 13 months. The patients primarily presented with a slowly enlarging painless deep dermal or subcutaneous mass. The mass was located in the head and neck region in 3 cases, elbow in 1 case and foot in 1 case. The patients underwent complete resection of the tumor, with no adjuvant chemotherapy and/or radiotherapy given. During a period of follow up for 10 to 29 months, all of them had no recurrence or distant metastasis. Gross examination showed that the tumor was well-circumscribed and had a grey-colored cut surface, with focal hemorrhagic cystic changes. The average tumor dimension was 1.9 cm. Histologically, the tumor was composed of histiocytoid or spindly cells arranged in nodular pattern. Fibrillary neuropil-type intercellular material was identified in all cases and a fibrous pseudocapsule surrounded by lymphocytes and plasma cells was demonstrated in 3 cases. Immunohistochemical study showed that all of them were positive for vimentin and negative for S-100 protein, pan-cytokeratin, CD34 and CD31. Three of the cases expressed desmin and CD68. Two cases were epithelial membrane antigen and CD99-positive.

CONCLUSIONSAFH is a rare tumor of intermediate malignant potential. Definitive diagnosis requires thorough histologic examination and clinical correlation. Immunohistochemistry is also helpful for diagnosis and differential diagnosis. Wide local excision with post-operative follow up is the main modality of treatment.

OBJECTIVETo evaluate the transhiatus esophagectomy for patients with esophageal cancer.

METHODSClinicopathological data of 46 patients with esophageal cancer undergone transhiatus esophagectomy by single surgeon team from May 2000 to July 2007 were analyzed retrospectively.

RESULTSThese 46 patients included 44 esophageal squamous cell carcinomas,1 esophageal adenocarcinoma and 1 esophageal carcinoid. The lesions of 11 patients located at neck segment, 21 at upper segment, 5 at middle segment, and 9 at lower segment. All the patients were classified according to UICC TNM stage classification: 3 cases as stage 0, 6 cases as stage I, 17 cases as stage II a, 2 cases as stage II b, 16 cases as stage III. Six patients received preoperative chemotherapy and pathological complete response was seen in 2 cases. Reconstruction with stomach was performed in 42 cases and with colon interposition in 4 cases.All the tumors were resected, and there was no perioperative death. All the resected margins were pathologically clear. Postoperative complications occurred in 12 cases and were successfully treated, including 2 cases of hoarseness, 3 cases of cardiac arrhythmia,1 case of bilateral pleural effusion, and 6 cases of small anastomotic leakage at neck.

CONCLUSIONTranshiatus esophagectomy is an ideal choice in surgical treatment for patients with esophageal cancer, especially for the ones of aged, poor cardiac or pulmonary function, who can not afford the thoracotomy.

OBJECTIVEto study the clinicopathologic features and differential diagnosis of low-grade central osteosarcoma (LGCOS).

METHODSnine cases of LGCOS were retrieved from the archival consultation files. The clinical, radiologic and pathologic features were analyzed, with literature review.

RESULTSthe mean age of the patients was 31 years. The male-to-female ratio was 3:6. All of the patients presented with painful mass and/or swelling. The sites of involvement included thigh (n = 4), tibia (n = 1), fibula (n = 1), cervical vertebra (n = 1), lumbar vertebra (n = 1) and maxilla (n = 1). Radiologic examination showed mixed lytic/blastic lesions with soft tissue shadow in 5 cases and associated periosteal reaction in 3 cases. The tumors were treated by surgical excision, with no adjuvant therapy given. The duration of follow up ranged from 2 to 43 months. Four cases had recurrence which occurred at 8 to 25 months after the operation. Gross examination showed that the tumors were fragmented on submission in 5 cases and en bloc in 4 cases. They had solid and firm cut surface, with various degree of grittiness. Histologically, LGCOS was characterized by the presence of hypocellular fibroblastic stroma associated with focal osteoid production. The spindly tumor cells showed mild degree of nuclear pleomorphism, with occasional mitotic figures demonstrated in all of the 9 cases. The newly formed neoplastic woven bone did not have any osteoblastic rimming. The bony trabeculae were slender and seam-like. Parallel arrays of woven bone were seen in 6 cases. Some of the bony trabeculae appeared irregularly branched and curved. The tumor cells permeated adjoining pre-existing bony trabeculae and bone marrow in all cases. Three cases also showed soft tissue involvement.

CONCLUSIONSLGCOS often posses important diagnostic pitfalls due to the relatively bland-looking tumor cell morphology and associated large woven or longitudinal seams of lamellar-like bone. Thorough understanding of the histologic features, when coupled with clinical and radiologic findings, are essential in arriving at a correct diagnosis.

Objective To observe the injury of high intensity focused ultrasound combined with radiotherapy (RT) to the pancreas,the unintended abdominal tissues and organs of swine in vivo.MethodsAccording to the criterion to grade the gross and histological injury of the pancreas and the unintended tissue,the scores of injury between the groups to get the data of safety and feasibility of high intensity focused ultrasound(HIFU)combined with RT were compared.Results There was a better tolerance in each group and no fatal complication was observed.For the pancreas there was significant difference for the combined group compared with the other groups.For the unintended target tissue there was no significance difference except the control group with the other groups.Conclusion HIFU combined with RT can increase the injury to the pancreas of the swine compared with HIFU alone; while there was no increase for the injury to the unintended target tissue.The main toxicity of combination treatment is the toxicity of RT and can be tolerated by the animals.If the HIFU treatment is strictly controlled,the combination of HIFU and RT is safe and feasible.

Objective To analyze the CT and MRI characteristics of the pineal region tumors (PRTs) to improve the accuracy of diagnosis and differential diagnosis.Methods The MRI and CT findings of 28 patients with PRTs proved by operation and pathology were retrospectively analyzed.Eight of them were performed preoperative 1H-MRS and DWI examination and thier data were analyzed too.Results of these 28 patients,11 were diagnosed as having germinoma,4 teratoma,3 astrocytoma,3 meningioma,2 pinealocytoma and 1 epidermoid cyst,1 pineoblastoma,1 hamartoma and 1 dermoidcyst.The main imaging characteristics were cystic tumors in the pineal region,variational density/signal intensity with few tumors having their specified morphology,density/signal intensity and enhancement style.The germinomas and the pineoblastomas were mainly homogeneous solid masses with symmetrical density/signal.The astrocytoma was cystic-solid,mostly,with changing shapes and odds density/signal.The mature teratoma showed blending density/signal.The 1H-MRS showed typical high Cho peak and low NAA peak in the astrocytoma; no NAA peak was found in the meningeoma; high Cho peak and no Lip peak were found in the pineoblastoma; the germinoma was noted having Lip peak.Conclusion Observation on the changes of the morphologic features,density/signal intensity and enhancement style can help in the differential diagnosis of PRTs.DWI and 1H-MRS examinations can improve the accuracy of differential diagnosis to some extent,but some PRTs remain to be non-differentiable.
