BACKGROUNDPancreatic cancer is one of the most aggressive human malignancies. Lymphangiogenesis plays an important role in lymph node metastasis of many solid tumors. It is well known that low molecular weight heparins (LMWHs) can inhibit cell growth, cell invasion and angiogenesis, which are key processes in tumor progression.
METHODSWe measured the expression of vascular endothelial growth factor C (VEGF-C) in pancreatic cancer cells (PANC-1) using reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting. We used an in vitro assay to evaluate the anti-lymphangiogenic effect of an LMWH, Fragmin, on human lymphatic endothelial cell (HLEC) proliferation.
RESULTSFragmin at a low concentration can effectively inhibits HLEC proliferation induced by VEGF-C. VEGF-C secreted by PANC-1 cells stimulated HLEC proliferation. Low concentration LMWH suppressed HLEC proliferation induced by VEGF-C but did not affect proliferation or VEGF-C expression of PANC-1 cells, whereas high concentrations of LMWH inhibited PANC-1 cell proliferation.
CONCLUSIONSThese results suggest that VEGF-C released by cancer cells plays an important role in promoting HLEC proliferation. The LMWH Fragmin has anti-lymphangiogenic effects and may inhibit lymphatic metastasis in pancreatic cancer.

OBJECTIVETo observe the impacts on skeletal fluorosis pain, joint motor dysfunction and urine fluoride excretion in the treatment with fire needle therapy, electroacupuncture and calcium carbonate D3.
METHODSThe randomized controlled trial was adopted. Ninety-five patients were randomized into a fire needle group (31 cases), an electroacupuncture group (33 cases) and a calcium carbonate D3 group (31 cases). In the fire needle group and the electroacupuncture group, Ashi points, Dazhui (GV 14), Geshu (BL 17), Quchi (LI 11), Hegu (LI 4), Xuehai (SP 10) points were selected and stimulated with fire needle and electroacupuncture separately, three times a week. In the calcium carbonate D3 group, calcium carbonate D3 tablets was prescribed for oral administration, 600 mg each time, twice a day. The duration of treatment was 2 months in the electroacupuncture group and calcium carbonate D3 group and 1 month in the fire needle group. VAS score, the range of motion (ROM) and urine fluoride value were compared before and after treatment in the patients of the three groups.
RESULTSAfter treatment, VAS value and ROM were improved significantly in the patients of the three groups (all P < 0.05), the difference was not significant in comparison of the three groups (all P > 0.05). After treatment, the urine fluoride value was increased significantly in the fire needle group [(7.89 +/- 3.61) mg/L vs (9.81 +/- 4.17) mg/L, P < 0.01] and was increased in the electroacupuncture group [(7.53 +/- 3.46) mg/L vs (8.97 +/- 4.21) mg/L, P < 0.05]. The difference was not significant in comparison before and after treatment in the calcium carbonate D3 group (P > 0.05).
CONCLUSIONThe fire needle therapy, electroacupuncture and calcium carbonate D3 all have the clinical value in the prevention and treatment of skeletal fluorosis and the difference in the therapeutic effect has not been discovered among them yet at present. But it has been found that the fire needle therapy and electroacupuncture display the active significance in the promotion of urine fluoride excretion.

Objective To analyze the safety and efficacy of laparoscopic radical resection of colorectal cancer for elderly patients over 70 years old. Methods From January 2014 to January 2017,a retrospective analysis of the patients with radical surgery for colorectal cancer in Department of General Surgery,Beijing Anzhen Hospital,Capital Medical University was performed. According to the patient′s age, the patients were divided into ≥70 years old group (68 cases) and<70 years old group (84 cases). The preoperative clinical data of the two groups were analyzed. The surgeons strictly followed the standard lymph node cleaning and the principle of no tumor for colorectal cancer radical operation. The surgical conditions, pathology,short-term efficacy and the follow-up conditions of the two groups were compared. Statistical analysis was performed using SPSS 20. 0. The normal distribution of the data was expressed as Mean±SD,and the t-test was used for comparison between the group. The count data was compared using the χ2 test or the Fisher exact probability method. Results The operation was successfully completed in both groups. In the group of≥70 years old,2 cases were converted to open due to extensive adhesion of the abdominal cavity,no perioperative death. Compared with the<70 years old group,≥70 years old group had more hypertension and coronary heart disease, respectively ( 38. 2%( 26/68 ) vs. 14. 3%( 12/84 )), and the difference was statistically significant ( P<0. 05 ) . There was no significant difference in intraoperative blood loss and operation time between the two groups (P>0. 05) . There was statistically significant difference in incidence of postoperative cardiovascular events between the groups (26. 4%(18/68) vs. 7. 14%(6/84)χ2= 6. 428, P=0. 010) . However,there were no significant differences between the two groups in implications,rate of death and the time stayed in hospital. (P>0. 05). Conclusion Laparoscopic radical resection for colorectal cancer patients over 70 years old is safe and feasible with strict indications and attention to perioperative management.

OBJECTIVETo study the human immunodeficiency virus (HIV) prevalence of residents living in a village located in rural region of central China where the paid blood donors used to be popular.
METHODSAll residents of one village "ZY" were asked to participate in HIV serologic screening test. Those over the age of 16 and participated in HIV serologic test was followed to undergo an indoor interview a week later, to finish a questionnaire, which including information on demography, marital status, smoking and drinking habits, history of blood donation, sexual behavior and history of drug use. Names on those either died from AIDS or having HIV serologic testing before were collected from local hospitals and the Center of Disease Control and Prevention.
RESULTSThere were in total 2364 residents in 527 households in "ZY" village including 1551 residents participated in the HIV serologic screening test, and 926 completed questionnaires. A total of 115 HIV seropositive residents were found in the HIV screening. 5 had been undergone HIV screening tests before, and 24 died of AIDS. The HIV prevalence of the whole population was 9.1% (CI: 7.7% - 10.6%). There were 19.6% households had at least one member living with HIV, out of which 25% had over two HIV seropositive members. No significant difference was found between genders with respect to HIV prevalence. 40 - 50 years old group had the highest HIV prevalence, significantly differed from other age groups. The HIV prevalence among former paid blood donors was 22.4%. The proportions of getting HIV infection through routes of blood transfusion, sex and mother-to-child, were 0.9%, 9.6% and 5.2% respectively among 115 HIV seropositive residents.
CONCLUSIONSome villages in the rural regions of central China showed high HIV prevalence. Former paid blood donation was responsible for the main transmission route in these villages. However, sexual transmission and mother-to-child transmission were becoming dominant routes in general population which called for effective action be taken to contain the spread of HIV.
