Objective　To study chemotherapy sensitivity and apoptosis in tumor cell line.Methods　Two different human colon carcinoma cell lines, LoVo and Ls-174-t were incubated with DDP,MMC,5-FU，EPI at various peak plasma concentrations (PPC), 1/10PPC，1/5PPC，5PPC and 10 PPC. Apoptosis was detected by FACScan and TUNEL technique after 24 hours and 48 hous. Cell growth inhibition rates were assessed by MTT, DNA ladder were examined by agarose electrophoresis.Results　At 48 hours, the highest cellular apoptosis rates were observed with PPC which was assessed by FACScan technique. There was a positive linear correlation between apoptosis assessed by TUNEL technique and growth inhibition rates of cells determined by MMT(P＜0.05).Conclusion　Using Annexin-V-Fluos staining FACScan technique to assess apoptosis of tumor cells is an exploring and useful method which can be used to choose both kinds and doses of chemotherapeutic drugs.

Objective To evaluate the techniques and effects of post-operational surgery of colorectal cancer for metastatic tumor on caudate lobe of liver. Methods For the patients admitted from Jan. 1999 to Jan. 2007 to the Navy General Hospital of PLA and undergone metastasectomy on caudate lobe of liver after colorectal cancer operation, the operative procedure and effects were studied retrospectively. Results A total of 18 cases of metastasectomy on caudate lobe of liver were successfully performed. The mean diameter of the metastases was 6.3cm (3.2-11.3cm). The types of operation included total caudate lobectomy (6 cases), total caudate lobectomy combined with extended hepatectomy (9 cases) and partial caudate lobectomy (3 cases). The mean operative time was 198min (154-360min) and the average intraoperative blood loss was 975ml (400-3250ml). No intraoperative death occurred, while the remarkable complications were found in 5 cases (27.8%). The survival rates of follow up for 1, 3 and 5 years were 83.3%, 61.1% and 27.8%, respectively. Conclusions The metastases on caudate lobe of liver after colorectal carcinoma resection usually involve all the hepatic portals. Surgical resection, though sophisticated in technique, remains to be a safe and effective treatment, and the first choice for treating metastases.

Objective To investigate the indications and results of combined liver-kidney transplantation.Methods From Jan. 2001 to Dec. 2003, 15 patients were subjected to combined liver-kidney transplantation in our department. The underlying diseases included hepatitis B viral cirrhosis complicated by HRS ( n= 8), hepatitis B viral cirrhosis complicated by uremia ( n =2), hepatitis B viral cirrhosis complicated by diabetic nephropathy ( n =1), polycystic liver and kidney disease ( n =2), Caroli's disease and polycystic kidney ( n =1), alcoholic liver cirrhosis complicated by uremia ( n =1). The surgical procedure, perioperative complications, acute and chronic rejection, the recurrence of hepatic viral B hepatitis, and the result of follow-up were analyzed.Results The graft function in 15 cases of combined liver-kidney transplantation was restored well after operation. The 6-month and one-year survival rate was 100%. One patient was supported by respiration machine for 48 days. The complications occurred in 3 patients after operation, including one case of gastroenternal bleeding repeatedly and one case of postoperative wound bleeding subject to non-surgical treatment, and one case of stenosis of biliary anastomosis subject to ERCP. Only one patient experienced a rejection episode of the liver. No acute rejection of the kidney graft occurred. One patient was died from liver graft function failure by recurrence of hepatitis B after 30 months.Conclusions Combined liver-kidney transplantation is only radical treatment method for patients with end-stage liver disease with chronic renal dysfunction or chronic renal failure. In the patients with hepatitis B,lamividine and hepatitis B immunoglobin can prevent the recurrence of hepatitis B.

Objective To understand the health of the electronic waste (e-waste) treatment workers and the adverse effects of e-waste on the workers engaged in e-waste dismantlement.Methods Health states were assessed by questionnaire investigation on 226 e-waste dismantlement workers and 172 non e-waste dismantlement workers (control group).Results The prevalence rates of headache/vertigo(47.7%),tetter /itch (15.0%),nausea(11.1%),insomnia(9.7%),hypomnesia (5.3%),nasal obstruction(5.3%),and conjunctiva congestion(4.8%) in e-waste dismantlement workers were significantly higher than that in the control group,and it seemed that the severity of the symptoms was strongly related to the type of work.Furthermore,there was a tendency that rate of insomnia raised with the length of service in the circuit boards dismantlement group.Conclusion E-waste dismantlement will produce adverse effects on health of the employed workers.

Objective:To study the mechanism of anti-proliferative effect of lupeol on highly metastatic human hepatocellular car-cinoma HCCLM3 cells. Methods:CCK-8 assay was performed to evaluate the effects of lupeol at different concentration on cell viability in 12-48 h. Caspase inhibitors were used to identify the subtypes of caspases activated during lupeol-induced cell death. The effects of lupeol on the mRNA expression of caspase family and Bcl-2 related genes were detected by real-time PCR. The effects of lupeol on HC-CLM3 cell phase distribution were investigated by flow cytometry. Results:Compared with the control group, lupeol could inhibit HC-CLM3 cell proliferation in a concentration-dependent manner with IC50 of 93 μmol·L-1 in 24h. The number of HCCLM3 cells in the period of G2/M was increased by 1-fold when the lupeol concentration was within 60-100 μmol·L-1 . Lupeol could activate the path-way of caspase, and the mRNA expression of caspase-3 was elevated by 50%-150% when compared with that in the control group. Mo-reover, the mRNA expression of p53 and Bax were increased above 1-fold by lupeol at 100 μmol·L-1 , and the Bcl-2 and PARP ex-pression were significantly suppressed by lupeol at 60-100 μmol·L-1(P<0. 05 or P<0. 01). Conclusion:The results indicate that lupeol has anti-proliferative effect on the liver cancer cells, which is beneficial to the prevention and treatment of liver cancer.
