In this article, the concept of complementary and alternative medicine (CAM) was reviewed, and the functions and status of Chinese medicine in malignant tumor therapy as a CAM were summarized. The major usage of Chinese medicine as a CAM in treatment of malignant tumor are as follows: (1) Chinese medicine alone can be used as an alternative therapy for advanced patients who cannot benefit from chemotherapy or radiotherapy; (2) Chinese medicine can be used together with chemotherapy or radiotherapy as a complementary therapy to alleviate signs and symptoms, reduce toxicities and increase effect; (3) Chinese medicine can be used as an alternative therapy for elderly or patients with poor performance status (PS); (4) it can also combine with new technology (e.g., extracorporeal high frequency thermotherapy, radioactive seed implantation, and radiofrequency ablation) as a complementary treatment; (5) Chinese medicine can work with molecular target therapeutic drugs to increase efficacy and sensitivity, reduce toxicities, improve quality of life and prolong survival; (6) Chinese medicine can act as a maintenance therapy after surgery, chemotherapy and radiotherapy; (7) Chinese medicine can also be taken as a preventive measure in high-risk patients with pre-cancerous diseases or "tumor-free" status. Finally, the author concluded the prescription pattern of Chinese medicine in treatment of malignant tumor, and presented several clinical effective cases treated with Chinese medicine.

ObjectiveTo explore the clinical diagnosis and surgical treatment of primary retroperitonealneurilemoma(schwannoma). MethodsClinicaldataof 47patientsof primary retroperitoneal schwannoma admitted and surgically treated from January 1995 to December 2009 were retrospectivelly reviewed.ResultsAs diagnosed by pathology there were 36 cases of Benign schwannoma,with a median age at onset of 41years, among those 11 patients were symptomatic, and 25 were asymptomatic. There were 11 malignant 11 cases, the median age was 38 years, among those 6 patients were symptomatic, and 5 were asymptomatic. The positive diagnostic rate of preoperative CT and MRI were 36. 2％ ( 17/47 ) and 58. 3％ ( 7/12 ) respectively. Immunohistochemically positive rates of S-100 were 100％ and 81.8％(9/11) in benign and malignant group respectively.All cases underwent surgical treatment. Surgical resection rates for benign and malignant groups were 100％ and 90. 9％(10/11)respectively. There was no perioperative death, Overall 5-year survival rates were 100％ and 45.5％ for benign and malignant tumors groups respectively. In benign group 2 cases recurred, in malignant group 4 cases recurred, and 3 had distant metastasis.ConclusionsPrimary retroperitoneal schwannomas are less common. It is difficult to make an accurate preoperative diagnosis. Surgery is the most effective therapy.Prognosis is good for benign and poor for malignant retroperitoneal neurilemomas.

Objective To investigate the surgical treatment strategies and prognostic factors of cT4bM0 primary rectal cancer.Methods The clinical data of 53 patients with cT4bM0 primary rectal cancer who were admitted to the First Hospital of Peking University from January 2000 to December 2010 were retrospectively analyzed.All the patients received en-bloc multivisceral resection and postoperative chemotherapy.The survival and prognostic factors were analyzed.The patients were followed up via out-patient examination,phone call or mail,and the follow-up was ended till December 2012.The survival curve was drawn using the Kaplan-Meier method,and the survival was analyzed using the Log-rank test.Uni-and multivariate analysis were done using chisquare test and COX's proportional hazard model.Results Of all the 53 patients,20 received posterior pelvic exenteration (PPE),20 received total pelvic exenteration (TPE),3 received low anterior resection (LAR) +local resection of ballder,2 received LAR + ovariectomy,2 received LAR + local resection of ureter,1 received LAR + local resection of posterior vaginal wall,1 received LAR + vesiculectomy and vesectomy,3 received abdominoperineal resection (APR) + local resection of posterior vaginal wall,1 received APR + sacrectomy.R0 resection was achieved in all the patients.No intraoperative death was observed,and the incidence of postoperative complication was 9.4％ (5/53).The results of postoperative pathological examination showed that 2 patients were with well-differentiated adenocarcinoma,41 with moderate-differentiated adenocarcinoma,and 10 with poorly differentiated adenocarcinoma.Twenty-four patients were with lymph node metastasis.Four patients were in TNM stage Ⅰ,25 in TNM stage Ⅱ and 24 in TNM stage Ⅲ.Fifty-three patients were followed up postoperatively,and the median time for follow-up was 33 months (range,4-116 months).The overall 5-year survival rates was 57.3％.The 5-year survival rate for patients with or without lymph node metastasis were 77.1％ and 30.4％,respectively,with significant difference between the 2 groups (x2 =7.374,P ＜ 0.05).The 5-year survival rates of patients with malignant infiltration and inflammatory adhesion mere 51.0％ and 68.5％,with no significant difference (x2=1.148,P ＞0.05).The 5-year survival rates of patients with malignant infiltration and inflammatory adhesion in stage Ⅱ were 74.6％ and 85.7％,with no significant difference between the 2 groups (x2=0.118,P ＞ 0.05).The 5-year survival rates of patients with malignant infiltration and inflammatory adhesion in stage Ⅲ were 28.8％ and 37.5％,with no significant difference between the 2 groups (x2 =0.959,P ＞ 0.05).The results of univariate analysis showed that lymph node metastasis and TNM stage were the risk factors influencing the prognosis of patients with cT4bM0 primary rectal cancer (x2=6.468,6.596,P ＜ 0.05).The results of multivariate analysis showed that lymph node metastasis was the independent risk factor (RR =3.797,P ＜ 0.05).Conclusions En-bloc multivisceral resection should be the first surgical treatment choice for patients with cT4bM0 primary rectal cancer,and lymph node metastasis is the independent risk factor.Under the same N stage,the prognosis of patients with malignant infiltration or inflammatory adhesion is similar if R0 resection is achieved.

AIM: Based on the finding of adipophilin expression with the increase in cellular cholesterol, the aim of the present study was to look for the active site of adipophilin in cellular cholesteryl metabolism. METHODS: Mouse peritoneal macrophages were incubated with 80 mg/L Ox-LDL (Ox-LDL group) or 80 mg/L Ox-LDL plus 1 mmol/L adipophilin antisense oligonucleotides (Ox-LDL+antisense group), respectively. At the various time points, the incubated cell samples were observed with adipophilin immunofluorescence staining, flow cytometric analysis and cellular cholesterol analysis. RESULTS: The Ox-LDL+antisense group cells contained significantly lower cholesteryl ester (19.9?1.9) mg/g (protein) than that of cells in Ox-LDL group (46.6?3.4) mg/g (protein) at 4 days. From 12 h, expression of adipophilin in Ox-LDL group increased more quickly than that of the cells in Ox-LDL+antisense group. At day 4, the level of adipophilin expression in Ox-LDL group was significantly higher than that in Ox-LDL+antisense group. During the observation, the amount of Ox-r[CL-3H] LDL taking up increased gradually in both groups, however, from day 1 the taking up amount in Ox-LDL+antisense group was less than that in Ox-LDL group. There was a statistical difference between the two groups from day 2 to day 4. From 6 h to day 2, the relative ACAT activity increased in both groups. The relative ACAT activity kept unchanged from day 2 to day 4 in the two groups. At day 2, the relative ACAT activity in Ox-LDL+antisense group was significantly lower than that in Ox-LDL group. Correlative analysis between activity of ACAT and adipophilin expression showed than R2 were 0.6176 and 0.8212 (P

Objective To investigate the feasibility of ultrasmall superparamagnetic iron oxide- enhanced(USPIO)-enhanced MR imaging for monitoring synovitis of antigen-induced arthritis in rabbit model and explore the optimal MR imaging sequences.Methods Nine female white rabbits with antigen(0.5 ml mBSA,2 mg/ml)induced arthritis of the right knees were used in the study.The left knees of these rabbits and both knees of another 3 rabbits served as the control.Nine to 28 days(mean 21.3 d)after successful model induction,all knees were imaged before and 24 h after intravenously injection of USPIO (0.3 ml/kg),among which 2 rabbits were also imaged at 48 and 72 h after administration of USPIO respectively.The MR protocol included spin-echo(SE) T_1WI,fast spin-echo(FSE)T_2WI,gradient echo (GRE)T_2~* WI and short tau inversion recovery(STIR).Images were analyzed quantitatively and qualitatively based on signal characteristics and patterns of the synovium.Paired t-test was used for the analysis of the signal intensity of inflammatory synovial membrane before and 24 h after injection of USPIO. MR findings were correlated with histopathology.Results Arthritis was successfully induced in all 9 right knees with intraarticular injection of mBSA.Pathological examination revealed hyperplasia of synovium with infiltration of USPIO-loaded-macrophages.MR depicted synovial thickening(thickness 2.07?0.97 mm) and joint effusion.Synovium and joint fluid appeared as slightly hypo- or iso-intense on T_1 WI and hyper- intense on T_2 WI or T_2~* WI.Twenty four hours after USPIO injection,significant T_1 enhancement(ASNR 41.91%?27.94%),negative T_2 and T_2~* enhancement(△SNR -34.92%?11.77% and -57.24%? 16.05%)were demonstrated in the region of synovial inflammation respectively.The signal at 48 h and 72 h changed less than that at hour 24.No signs of arthritis occurred in all left knees and in all knees of the artificial model group.Conclusion Iron oxide phagocytized into macrophages can be a root cause resulted in signal change on USPIO-enhanced MR images.The gradient echo sequence should be the optimal sequence to be used in USPIO-enhanced MR imaging in antigen-induced arthritis.

ObjectiveTo explore the expression of N-cadherin and β-catenin mRNA in human brainstem and supratentorial gliomas. MethodsN-cadherin and β-catenin mRNA expression in 18 cases of brainstem gliomas and 18 cases of supratentorial gliomas tissues were detected with PT-PCR. Resultsβ-catenin mRNA expression was more in human brainstem gliomas than in supratentorial gliomas （t=2.255,P<0.05）, but was not significantly different of N-cadherin mRNA (P＞0.05). The expression of N-cadherin mRNA in human brainstem gliomas of grades Ⅰ～Ⅱ were less than those in human gliomas of grades Ⅲ～Ⅳ (t=2.711，P<0.05), but was not of β-catenin mRNA (P＞0.05). N-cadherin mRNA expression was positively correlated with the β-catenin mRNA expression in either brainstem gliomas or supratentorial gliomas （r=0.480，r=0.809 respectively, P<0.05）. ConclusionThe over expressions of N-cadherin and β-catenin may play an important role in the invasion and malignant progress of human brainstem gliomas.

OBJECTIVE To evaluate the genotoxicity of naproxen (NPX) impurities acetylnerolin (Ace). METHODS The genotoxicity of Ace was predicted by ADMET, Derek and Sarah with the quanti?tative structure-activity relationship (QSAR). The chromosomal aberration and bacterial reverse-muta?tion (Ames) tests were performed to verify the above results. In chromosomal aberration tests, CHL cells were incubated with Ace 10, 20 and 40 mg · L-1 for 4 h in the presence or absence of metabolic activation system solution (S9 mix). Methyl methane sulfonate (MMS) 20 mL · L-1 without S9 mix and cyclophosphamide (CP) 12 mg · L-1 with S9 mix served as positive control. The number of chromo?somes in each aberrant metaphase (including fissure, exchange, ring, break and polyploid) was counted and recorded, when the distortion rate less than 5％was considered negative and more than 10％was considered positive. In Ames test, the potential mutagenicity was evaluated using five strains of S. typhimurium ( TA97,TA98,TA100,TA102 and TA1535). They were treated with Ace 5, 25, 125 and 625μg per plate with or without S9 mix and incubated for 48-72 h. When without S9 mix, Dexon 50μg per plate served as positive control for TA97 and TA98, MMS 2.0μL per plate served as positive control for TA100 and TA102, and sodium azide 1.5μg per plate served as positive control for TA1535. When with S9 mix, 2-AF 100 μg per plate served as positive control for TA97, TA98 and TA100, 1, 8-dihydroxyanthraquinone (100μg per plate) served as positive control for TA102 and CP 50μg per plate served as positive control for TA1525. When the number of colonies was at least two-fold that of the negative control, the compound was considered mutagenic. RESULTS Although the Derek and Sarah software predicted that the NPX impurities were not genotoxic, ADMET data showed that Ace could induce chromosomal aberrations. The distortion rate of Ace 40 mg · L-1 was greater than 5％, but less than 10％. The distortion rate of Ace was less than 5％when<20 mg·L-1. Consistent with the results of ADMET, Ace might induce chromosomal aberrations. Ames test results showed that Ace did not signifi?cantly increase the number of bacteria (5-625μg per plate) compared with the negative control. Contrary to the ADMET results, Ace had no mutagenicity. CONCLUSION Ace has potential chromosomal muta?genicity. For life-long usage of NPX, the content of Ace should be reduced from 0.15％of conventional impurities to 0.015％.
