The liver is the most common site of colorectal cancer metastasis(CRLM). The importance of how to treat CRLM has attracted attention from doctors world wide and specific academic organization and expect consensus has been established. Relative principals of treatment of CRLM also developed in China, for example, guideline of diagnosis and treatment of colorectal cancer liver metastasis(draft) and standard for diagnosis and treatment of colorectal cancer, which were established in 2008 and 2010, respectively. However, we found that the Chinese doctors still understand these treatment policies inadequately, and easily produce deviation on the treatment progress. Based on the problems of current CRLM treatment, we have some thoughts or suggestions as follows: (1)Promoting the core conception of CRLM treatment actively: surgery is the only method to achieve possible cure of the CRLM. (2) Evaluating the status of new adjuvant chemotherapy for CRLM dialectically. (3)Paying attention to multi-disciplinary team(MDT): MDT is the scientific treatment foundation of CRLM. (4)Changing the treatment conception of primary tumor of CRLM: radical resection of primary tumor is essential for the resectable CRLM.(5)Emphasizing the surgical treatment of CRLM combined with lung metastasis. (6)Do not neglect the safety of patients, when we emphasize the surgery is the optimal treatment of CRLM. These guides of treatment of CRLM will improve the outcomes of CRLM around the world, but we still need pay attention to above mentioned points in order to insure the standardization and scientification of CRLM therapy.

ObjectiveTo evaluate the therapeutic efficacy of low-dosage methyltestosterone or andriol in men with senile osteoporosis. MethodsA total of 134 male patients with senile osteoporosis and the decreased serum level of free testosterone were divided into three groups. 45 patients were treated with low-dosage methyhestosterone(100 mg, once a day, sublingual) and 46 patients were treated with low-dosage andriol (40 mg, once a day, orally), while 43 patients were treated with placebo. The duration of treatment in each group was 1 year. The bone density, blood and urine biochemical indexes related to bone metaholites,the quality of life indexes, ultrasonography for prostate,serum prostate specific antigen,blood routine, urine routine, hepatic and renal function were detected before and after the treatment. ResultsBoth low-dosage methyltestosterone and low-dosage andriol could prevent the decrease of bone mineral density and improve patients' general health, role-emotional function and vitality (all P＜0.05). The difference values of femoral neck bone mineral density before and after treatment with low-dosage andriol and low-dosage methyltestosterone were (0.14+0.18)g/cm2 and (0.12±0.09)g/cm2 , respectively(P＜0.05). Low-dosage andriol hadstronger effects in increasing the level of estradiol (32.5±14.2 )ng/L than low-dosage methyltestosterone(19.3±9.2)ng/L(P＜0.05) and showed more notable effects in improving the physical functioning and role-physical function than low-dosage methyhestosterone. The use of the two androgenic hormones at low dosage showed safety. ConclusionsBoth low-dosage methyltestosterone and low-dosage andriol can be used to treat senile osteoporosis in men and to improve life quality. Both of them are effective and safe therapeutic choices.

Objective To investigate the effect of different Chinese herbs on cell proliferation and cartilage oligomeric matrix protein(COMP)expression in chondrocyte culture.Methods Chondrocytes isolated from rabbit knee cartilage were cultured for 3 generations with the density of 2?10~4/cm~2 and were verified by collagenⅡimmunohistochemical staining.Rabbit sera containing herbs were obtained after animals orally ad- ministrated herbs at the dosage equivalent to human.At 5% and 10% serum density,cells were cultured in the medium that contained liver-softening herbal compound sera.Subgroups setting at 1,3 and 5 hours after herb intervention were observed.Rabbit and bovine sera were control groups.Seven days after intervention,chon- drocytes proliferation was observed using the MTT assay kit.For the study of COMP expression,chondrocytes were isolated from human knee cartilage supematant.Superuatant COMP level was tested by enzyme-linked immunoabsorbent assays(ELISA)after directly adding compound and extract from liver-softening herbs to the culture at the final concentration of 10 mg/ml for 3 days.Results Liver-softening herbal compound group had significant effect on cell proliferation compared to control,of which,3-hour subgroup was more significant than 1-and 5-hour subgroups(P

Pancreatic cancer is a highly lethal disease in gastrointestinal malignant tumors.The mortality of pancreatic cancer closely parallels its incidence.Most patients with pancreatic cancer remain asymptomatic until the disease reaches an advanced stage.There is no program for screening patients at high risk of pancreatic cancer.Although CT,MRI,positron emission tomography,endoscopic ultrasonography,and endoscopic ultrasonography-guided fine-needle aspiration offer high diagnostic ability for pancreatic cancer,it cannot be found at the early stage easily.Surgical resection is regarded as the only potentially curative treatment and adjuvant chemotherapy is given after surgery.This article reviews epidemiology,risk factors,diagnosis and treatment for pancreatic cancer by summarizing relevant literature.

Objective: To explore the correlation between serum level of high molecular weight adiponectin (HMW-ADPN) and arteriosclerosis. Methods: Clinical data of 87 middle-aged and aged people living in home, who underwent health examinations in Xiangya second hospital from Jan 2011 to Dec 2011, were collected. According to carotid-femoral pulse wave velocity (cf-PWV) = 9 m/s, they were divided into group A (cf-PWV<9 m/s, n=21) and group B (cf-PWV≥9 m/s, n=66). Blood pressure, blood lipid, blood glucose etc. were measured and compared between two groups. Results: Compared with group A, there were significant rise in blood pressure, levels of low density lipoprotein cholesterol, triglyceride and total cholesterol, and significant reduction in levels of high density lipoprotein cholesterol (HDL-C), serum total ADPN and HMW-ADPN in group B, P<0.05 or <0.01. Multiple regression analysis indicated that serum HMW-ADPN (B= - 4.469，P=0.011), total ADPN ((B= - 3.965，P=0.012), HDL-C（B= - 2.077，P=0.015) and systolic blood pressure levels (B= 0.045，P=0.045) were independent predictors of cf-PWV. Conclusion: Serum high molecular weight adiponectin and total adiponectin levels may be protective factors against arteriosclerosis. Its role in predicting occurrence and development of arteriosclerosis is worthy of further study.

OBJECTIVETo observe the effect of Feiyanning Granule (FYN) on tumor growth and cell cycle distribution in mice with Lewis lung cancer, as well as its influence on G1/S cell cycle checkpoint dominating signaling RB-E2F1 bio-axis.

METHODSModeled C57BL/6 mice were randomly divided into 6 groups: the model group (A), the DDP treated group (B) peritoneally injected with cisplatin 0.1 mg on d1, d3 and d5 after modeling, and the 4 FYN treated groups (C-F), administered via gastrogavage with FYN Decoction, and FYN Granule in small-, median- and high- dose respectively for 14 days. The tumour inhibiting rate, tumour weight, and body weight of mice were observed after treatment; cell cycle distribution was detected by flow cytometry (FCM), RB-E2F1mRNA expressions in tumour tissue were analyzed by RT-PCR, and their protein expressions by Western blot.

RESULTSTumour weight in the 5 treated groups was lower than that in the model group (P < 0.05, P < 0.01). Body weight in group E was significantly higher than that in group A and B (P < 0.05, P < 0.01). FCM analysis showed the proportion of G0/G1 phase was higher in group E than in group A, B and C (P < 0.01), and cancer cell proliferation index (PI) in group E was lower than in group B (P < 0.05, P < 0.01). RT-PCR showed mRNA level of E2F1 was lower, but that of RB was significantly higher in group E than those in group A, B and C respectively (P < 0.01). Westem blot analysis showed the protein expression of E2F1 was lower in group E and B than that in group A (P < 0.05), while the protein expression of Rb in group E was higher than that in group A, B and C (P < 0.05).

CONCLUSIONThe effect of FYN in inhibiting Lewis lung cancer growth was related to its intervention on cancer cell cycle distribution which blocks most tumor cells in G0/G1 phase. Moreover, FYN can reduce MDM2 expression, enhance P53 expression to influence cell cycle G1/S checkpoint dominating signaling, so as to achieve the effect of antagonizing lung cancer cell proliferation.
