From 2000 to 2004, the National Natural Science Foundation of China (NSFC) accepted 1 171 applications and funded 160 projects for fundamental research on integrated traditional Chinese and Western medicine. The success rate is 13.64%. Being supported by NSFC, a number of achievements well known in China and abroad have been made, such as acupuncture complementary anaesthesia, treatment of leukemia, viral hepatitis, cardio-cerebrovascular diseases, acute abdomen, burns and fracture with integrated traditional Chinese and Western medicine and their therapeutic mechanisms, and some new concepts and theories have been put forward, such as the theories of activating blood to resolve stagnation, simultaneous treatment of bacteria and toxin, etc. But there still exit some problems in the research of the funded projects. The research ways are mainly combination of different methods instead of integration of both traditional Chinese and Western medicine. The research results are mainly confirmation of traditional Chinese medical theories instead of exploration of their innate regularities. The relationship among disease, syndrome and symptom is not clearly explored. The principal-subordinate relationship between macro- and micro-differentiation of syndromes is not clear. Academic research is short of new ideas. Improper or biased explanation of the theories of traditional Chinese medicine still exists. On analysis of above problems, some preferable aspects of projects for fundamental research on integrated traditional Chinese and Western medicine funded by NSFC in future are suggested in this article.

A 59-year-old man with myelodysplastic syndrome who was hospitalized for evaluation of fever and generalized fatigue had elevated levels of C-reactive protein and pancytopenia. A search for a site of infection and empiric treatment with antibiotics were unsuccessful. Over 5 to 6 weeks right upper quadrant pain and rebound tenderness developed. Sonographic Murphys sign was present. Computed tomography showed thickening of the gallbladder wall, and repeated ultrasonography demonstrated changes consistent with cholecystitis. Open cholecystectomy was performed as an emergency procedure. Macroscopically the resected gallbladder showed an edematous and thickened wall. Histopathologic examination revealed transmural infiltration by atypical mononuclear cells with distinct nuclei. The cells showed immunohistochemical staining for CD15, indicating myeloid lineage. By 10 days after surgery, counts of leukocytes and leukoblasts had markedly increased, reaching 36,700/microL and 76.0%, respectively. The blast crisis was thought to indicate progression from myelodysplastic syndrome to leukemia. The patient died of progressive disease 12 days after surgery. We have described a rare case of acute cholecystitis caused by infiltration of immature myeloid cells to the gallbladder. An acute abdomen complicating hematologic disorders is life-threatening and requires prompt and appropriate treatment.

Well-differentiated papillary mesothelioma (WDPM) is an uncommon mesothelial tumor that occurs in the peritoneum of women over a wide age range. Although considered a tumor of uncertain malignant potential, information about its biological behavior is still limited. In this study, we present the clinicopathologic features of 26 cases of WDPM of the female peritoneum seen in our institution over a 20-year period (1990 to 2010). Clinical information and pathology material were reviewed in all cases. Patients ranged in age from 23 to 75 years (median, 47 y; mean, 48.6 y). There was no history of asbestos exposure in any of our cases. Ten patients had undergone surgery previously, and 6 had a history of endometriosis. In 24 patients, the WDPM was an incidental finding during surgery for a benign or malignant lesion. Only 2 patients presented with symptoms: 1 with an acute abdomen and the other with chronic pelvic pain. The former had developed a small hemoperitoneum because of bleeding of 1 of the lesions of WDPM, whereas the latter had a 2-cm WDPM involving the distal fallopian tube. The lesions were single or multiple (13 cases each) and ranged in size from 0.1 cm to 2 cm. The following sites were involved: abdominal or pelvic peritoneum not otherwise specified (10 cases), omentum (7 cases), cul-de-sac (6 cases), colonic serosa (4 cases), small bowel mesentery (2 cases), uterine serosa (2 cases), stomach serosa (1 case), large bowel mesentery (1 case), fallopian tube (1 case), ovary (1 case), and inguinal hernia (1 case). In all cases the lesions were excised. Microscopically, all of our cases had the typical features described for WDPM (ie, a papillary architecture that may be accompanied by glandular/tubular patterns, nests of cells and individual cells, bland mesothelial cells, absent or rare mitotic figures). The initial diagnosis in our cases was variable, including WDPM, mesothelial hyperplasia, malignant mesothelioma, serous tumor of low malignant potential of the peritoneum, papillary endosalpingiosis, and chronic xanthogranulomatous salpingiosis. Follow-up was obtained for 25 patients, and it ranged from 4 to 192 months (mean, 47.5 mo; median, 32 mo); 22 patients are alive with no evidence of WDPM after a follow-up that ranged from 5 to 144 months. One of these patients experienced recurrence of WDPM 46.5 months after initial diagnosis. In this patient, WDPM was an incidental finding during a total abdominal hysterectomy and bilateral salpingo-oophorectomy for serous cystadenofibroma. The recurrence was also an incidental finding during a colectomy for colonic adenocarcinoma. This patient is alive with no other recurrences 73 months after initial diagnosis and 36 months after diagnosis of the recurrence. Three patients died of other causes: pancreatic cancer at 4 months and 12 months and leukemia at 192 months. Recognition of the histologic features of WDPM and proper clinical correlation allow for the correct diagnosis of this entity. If necessary, immunohistochemical studies such as calretinin and keratin 5/6 facilitate the recognition of the mesothelial nature of this neoplasm. Although no patient died of disease in this series, follow-up of patients with this diagnosis is warranted on the basis of possible recurrences or misdiagnosis of an undersampled malignant mesothelioma.

The patient was a 66-year-old woman with left breast cancer who underwent left segmental mastectomy with sentinel lymph node biopsy. The histopathological diagnosis was estrogen receptor-positive (ER+), progesterone receptor-positive( PgR+), human epidermal growth factor receptor-2-equivocal( HER2()2+)( with no HER2 gene amplification by fluorescence in-situ hybridization analysis) invasive ductal carcinoma (scirrhous carcinoma) with Ki-67 expression of less than 10% (pathological T1c, N0, M0, stage I). The patient requested chemotherapy, and 4 cycles of docetaxel plus cyclophosphamide (TC) were scheduled. Fever and epigastric pain developed on day 13 of cycle 2. On day 22, the patient was examined before the third cycle of TC, and right lower abdominal pain was reported. Computed tomography revealed appendicitis and an intraperitoneal abscess. She was admitted to the hospital and underwent partial ileocecal resection. The patient was discharged on the 12th postoperative day with no further complications. Acute abdomen during chemotherapy for malignant tumors has been reported sporadically in patients with leukemia. A diagnosis of acute abdomen in patients undergoing cancer treatment requires careful assessment of gastrointestinal symptoms such as nausea and vomiting during chemotherapy, fever associated with granulocytopenia, and findings indicative of local inflammation. The patient in this case recovered uneventfully because imaging studies and surgery were performed promptly after presentation.

Intussusception is rarely reported in adult patients with acute leukemia. We report a case of intussusception in a 29-year-old woman with acute myeloid leukemia (AML). She developed right lower quadrant pain, fever, and vomiting on day 16 of induction chemotherapy. Physical examination showed tenderness and guarding at the right lower quadrant of the abdomen. Abdominal computed tomography (CT) showed distension of the cecum and ascending colon, which were filled with loops of small bowel, and herniation of the ileocecal valve into the cecum. We proceeded to laparotomy and revealed ileocecal intussusception with the ileocecal valve as the leading point. The terminal ileum was thickened and invaginated into the cecum, which showed gangrenous changes. Right hemicolectomy was performed and microscopic examination of the colonic tissue showed infiltration of leukemic cells. The patient recovered after the operation and was subsequently able to continue treatment for AML. This case demonstrates that the diagnosis of intussusception is difficult because the presenting symptoms can be non-specific, but abdominal CT can be informative for preoperative diagnosis. Resection of the involved bowel is recommended when malignancy is suspected or confirmed. Intussusception should be considered in any leukemia patients presenting with acute abdomen. A high index of clinical suspicion is important for early diagnosis.

<strong>BACKGROUND</strong> Appendicitis is the most common cause of an acute abdomen. Approximately 1% of appendicectomies will have an incidental finding of an appendiceal neoplasm. A primary appendiceal lymphoma is extremely rare, and is found in 0.015% of all appendiceal specimens. Burkitt lymphoma is an aggressive B cell lymphoma characterized by translocation and dysregulation of the c-Myc gene. Burkitt leukemia is considered to be an alternative manifestation of the same pathology, and is defined by the presence of >25% Burkitt blasts within the bone marrow. The treatment approaches for Burkitt leukemia/lymphoma are similar. <strong>CASE REPORT</strong> A 6-year old girl presented with a history, examination, and radiological imaging consistent with acute appendicitis. An inflamed, edematous appendix was identified intraoperatively, and a cecectomy was performed. Histopathological investigations demonstrated Burkitt leukemia with isolated extra-nodal involvement of the appendix. The patient was subsequently started on a multi-agent steroid and chemotherapy regimen. A literature review was performed, identifying cases of Burkitt leukemia/lymphoma presenting as appendicitis. <strong>CONCLUSIONS</strong> This case highlights the importance of clinical vigilance and routine specimen histopathology review, and explores key management considerations associated with the incidental diagnosis of Burkitt leukemia/lymphoma.
