OBJECTIVETo observe the therapeutic effect of traditional Chinese medicine (TCM) and Western medicine (WM) treatments on mycoplasmal pneumonia in children and the changes in the serum cytokines.

METHODSNinety children with mycoplasmal pneumonia were randomly divided into the treatment group and the control group. TCM was given orally and azithromycin at the daily dose of 10 mg/kg was administered intravenously in the treatment group. In the control group, only intravenous azithromycin was given. After a 7-day treatment, the response rate, time of symptom disappearance, and serum levels of IL-6, IL-8 and TNF-alpha were observed.

RESULTSThe total response rate was 93.33% in the treatment group and 73.33% in the control group, showing a significantly better therapeutic effect in the treatment group (P<0.05). The combined treatments also showed better effects in alleviating fever, coughing and rales (P<0.05), and resulted in more obvious reduction in the serum levels of cytokines (P<0.05).

CONCLUSIONCombined treatment with TCM and WM produce good therapeutic effects in children with mycoplasmal pneumonia.

OBJECTIVETo evaluate application of the sponge of demineralized bone matrix (SDBM) in tissue engineering of bone.

METHODSSDBM was prepared from long bone of rabbits. Bone marrow cells were flushed from the bone shaft of femurs of a two-month-old New Zealand white rabbit. After the cells were cultured for 9 days, the flasks were added into dexamethasone (10(-8) mol/L), beta-glycerophosphate sodium (10 mmol/L) and L-ascorbic acid (50 micrograms/ml). After 5 weeks, the cultured cells were collected and marked by 5-Bromo-2'-dexyouridine (BrdU). The grand sum of cells seeded on a piece of SDBM was about (4-6) x 10(6). The composites of cells and SDBM (tissue engineered chip, TEC) were implanted into muscles and bone defects of radius in rabbits. A standard procedure was applied to make a 10 mm long defect bilaterally in the radius of nine skeletally mature male New Zealand white rabbits. All of the 18 defects were randomly divided into three groups: group I, six defects were grafted by TEC; group II, six defects were grafted with SDBM alone; group III, six defects were empty.

RESULTSThe results of radiographic and histological evaluation showed that all of the defects were repaired in group I and group II at 6 weeks, none of the defects was repaired in group III. The results of BrdU staining showed that the staining was positive in group I, but negative in group II. Biomechanical test showed that the compressive ultimate strength (CUS) of new bone in TEC implanted group was comparable with normal radius (P = 0.623) and in SDBM implanted group was significant lower than normal radius (P = 0.038).

CONCLUSIONSThe TEC can form cartilage and bone tissue in muscles and repair segmental bone defects. SDBM is a kind of effective natural scaffold in tissue engineering of bone.

OBJECTIVETo analyze the prognostic factors of colorectal cancer patients with synchronous liver metastasis treated by simultaneous colorectal and liver resection.

METHODSThe clinical and follow-up data of 44 colorectal cancer patients with synchronous liver metastases who underwent simultaneous colorectal and liver resection from Jan. 1993 to Jan. 2003 were analyzed retrospectively. Survival rate was estimated by Kaplan-Meier method, and was compared using log-rank test. Prognostic factors were analyzed by multivariate Cox proportional hazards model.

RESULTSThe overall 1-, 3- and 5-year survival rates were 86.3%, 40.9% and 25.0%, respectively. The lymph node metastasis and vascular invasion by cancer cells from the primary tumour were found to affect prognosis significantly, while gender, age, tumor location, histopathological types, the number and distribution of liver metastases were not. Multivariate analysis revealed that the lymph node metastasis was the only independent prognostic factor.

CONCLUSIONSimultaneous liver and colorectal resection can be performed and may achieve good outcome in colorectal cancer patients with synchronous liver metastases, especially in those without lymph node metastasis.

OBJECTIVETo evaluate the prognostic factors for patients who underwent curative resection of pulmonary metastases from colorectal cancer.

METHODSThe clinicopathological data of 60 patients with pulmonary metastases from colorectal carcinoma who underwent a radical pulmonary metastasectomy between February 1985 and December 2004 at the Cancer Hospital of Chinese Academy of Medical Sciences were retrospectively reviewed and analyzed.

RESULTSThe overall 5-year survival rate was 43.7% after pulmonary excision and 74.0% after colorectal resection. Three factors were identified as significant by univariate log-rank test for overall survival after pulmonary resection, they were preoperative carcinoembryonic antigen, number of pulmonary metastases (solitary vs. multiple), and hilar and/or mediastinal lymph node metastases (P < 0.05). Multivariate analysis showed that number of pulmonary metastases (solitary vs. multiple) and hilar and/or mediastinal lymph node metastasis were independent prognostic factors. However, shorter disease-free interval and more number of pulmonary metastases predicted poor prognosis after primary colorectal resection.

CONCLUSIONPulmonary resection for metastases from colorectal cancer is safe and patients may get long-term survival in selected cases, especially in patients with a solitary pulmonary metastasis and without hilar and/or mediastinal lymph node metastasis.

OBJECTIVETo investigate the association between the number of retrieved lymph nodes and the prognosis of stage II colorectal cancer.

METHODSClinical data of 380 patients with stage II colorectal cancer were analyzed retrospectively. SPSS 13.0 was used for data processing. Survival rate was calculated by Kaplan-Meier method, and risk factors related to prognosis of stage II colorectal cancer were analyzed by Logistic regression analysis. Recurrence rate and survival rate were assessed with Chi-squared test.

RESULTSThe average number of lymph nodes retrieved from 56 patients who developed recurrence or metastasis in 5 year after surgery was 9.5, and 16.3 from patients who had no recurrence or no metastasis(P<0.01). The number retrieved from 97 patients who died in 5 years after surgery was 11.1, and 16.7 from survivors. Patients were divided into 2 groups:>or=12 group and <12 group. The 5-year survival rate was 83.9% in >or= 12 group and 62.0% in < 12 group, respectively(P<0.01), the recurrence rate was 6.4% in >or=12 group and 25.7% in < 12 group (P<0.01). The univariable analysis showed that the number of retrieved lymph nodes was significantly associated with the survival and recurrence in patients with stage II colorectal cancer (P<0.05).

CONCLUSIONSThe number of retrieved lymph nodes is associated with the prognosis of stage II colorectal cancer. Patients with more retrieved lymph nodes have a higher survival rate.
