OBJECTIVETo discuss the safety line to avoid the post-hepatectomy hepatic insufficiency by combining indocyanine green test by pulse dye-densitometry (PDD-ICG) and standard remnant liver volume (SRLV).

METHODSSeventy-five hepatic cancer patients undergone hepatectomy from March 2007 to February 2008 were included. According to the liver function decompensatory grades after operation, the relationship between ICG retention rate at 15 min (ICGR15) and standard remnant liver volume by linear regression were analyzed.

RESULTSThere were 60 cases with slight hepatic insufficiency, 12 cases with moderate hepatic insufficiency, and 3 cases with severe hepatic insufficiency. There were no difference in age [(50 +/- 13) years old and (53 +/- 9) years old], prothrombin time [(13.6 +/- 1.0) s and (13.5 +/- 1.0) s], international normalized ratio (1.09 +/- 0.10 and 1.06 +/- 0.10) between slight hepatic insufficiency group and moderate and severe hepatic insufficiency group (P > 0.05). And there were difference in K value (0.20 +/- 0.04 and 0.17 +/- 0.03), ICGR15 (6 +/- 4 and 9 +/- 4), SRLV [(545 +/- 93) ml and (398 +/- 82) ml] between two groups (P < 0.05). Compared ICG test and standard remnant liver volume of the patients with moderate hepatic insufficiency after operation, the liner relationship was found (R = 0.640, P = 0.025), and the regression equation was: standard remnant liver volume (ml/m(2)) = 1594.6 x ICGR15 + 265.

CONCLUSIONSPDD-ICG test and standard remnant liver volume are effective to estimate hepatic function reserve of patient undergone hepatectomy.

OBJECTIVETo investigate the time trends of cancer mortality among residents in Kaifeng county, Henan province.

METHODSData on cancer mortality from the vital registration system in Kaifeng county from 1988 to 2005 was analyzed. A total of 9543 death records (5974 males and 3567 females) due to malignant tumors were studied. A two-year-period age-specified standardized mortality rates were directly adjusted by the world standard population, and the annual percentage change (APC) of mortality were estimated by a linear logarithm regression.

RESULTSThe crude cancer death rate for male was 95.09/100,000 and its age-standardized death rate was 117.41/100,000. While, the crude cancer death rate for female was 59.13/100,000 and the age-standardized death rate was 57.15/100,000. There was a significant growth tread for lung cancer (APC: 6.54%), liver cancer (5.07%) in males and breast cancer (7.04%) in females in the groups aged over 18. On the contrary, the decreasing treads for esophageal cancer in both of sexes (-7.09%, -13.53%) were also observed in this study. Meanwhile, there was no other significant changes in the trend, either in the tumor sites or mortality, was observed.

CONCLUSIONIn the past two decades, there has been a significant increasing trend for cancer mortality in Kaifeng county, of Henan Province. Hence, it is necessary to enhance epidemiological survey to identify risk factors at the earlier stages.

OBJECTIVETo investigate the association between genetic polymorphisms in methylenetetrahydrofolate reductase (MTHFR) and risk of breast cancer among women.

METHODSTwo hundred seventeen cases with breast cancer and 218 matched controls were genotyped for the MTHFR C677T and A1298C polymorphisms by PCR-RFLP methods. The adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using unconditional logistic regression model.

RESULTSWe found that the frequency of the MTHFR C677TT genotype among cases was significantly different from that among controls (32.7% vs. 24.8%; P = 0.02). The MTHFR C677TT genotype had an increased risk of breast cancer compared with the 677CC genotype (95% CI, 1.09 - 3.14). No significant association between the MTHFR C677T or A1298C polymorphism and risk of the cancer was observed.

CONCLUSIONThese findings suggest that 677CT polymorphism in MTHFR may be a genetic susceptibility factor for breast cancer among Chinese women.

OBJECTIVETo study the use of vein grafts in adult-to-adult (AA) living donor liver transplantation (LDLT), we transplanted recipient vena saphena magna grafts for drainage of the paramedian portion of the right lobe liver grafts without a middle hepatic vein in LDLT.

METHODSFrom January 2002 to March 2006, 26 patients underwent A-A LDLT, and recipient saphenous vein grafts were used for revascularization of veins and arteries such as: tributaries of the middle hepatic vein from V5, V8; right inferior hepatic vein; injured portal vein; and hepatic artery.

RESULTSTotal outflow reconstruction ratio of V5, V8 and right inferior hepatic vein was 76.9% (20/26), the ratio of one-vein reconstruction was 57.7%, and the ratio of two-vein reconstruction was 19.2%. Reconstruction patterns and cases were demonstrated as follows: V5 (n=3), V8 (n=2), V5 and V8 (n=3), V5 and right inferior hepatic vein (n=1), V8 and right inferior hepatic vein (n=1), right inferior hepatic vein (n=10), injured portal vein of the donor (n=1). Total ratio of hepatic artery bypass grafting was 11.5% (3/26), anastomosis between hepatic artery and abdominal aorta (n=2), and anastomosis between hepatic artery and hepatic artery (n=1). Doppler ultrasound showed no thrombosis and the blood flowed smoothly and without venous outflow obstruction during the 2 to 48 months follow-up period.

CONCLUSIONReconstruction of V5 or V8 outflow and hepatic artery bypass grafting using vena saphena magna of the recipients can provide sufficient venous outflow and prevent the small-for-size syndrome and solve hepatic artery complications. This approach can be recommended.

OBJECTIVETo study the pathological changes of the liver tissues of patients with HIV infection.

METHODS14 biopsy and 12 autopsy liver tissues were examined histologically. HIV-1 related antigen of outer membrane protein gp120 and capsid protein p24 were examined with their corresponding monoclonal antibodies by immunohistochemistry.

RESULTSIn the biopsy group, cytomegalic virus (CMV) infection was found in one (1/14) case, outer membrane protein gp120 and/or capsid protein p24 antigen were detected in Kupffer cells and in some of the lymphocytes in 11 cases. All the hepatocytes were negative for outer membrane protein gp120 and capsid protein p24 antigens. In the autopsy group, there were 5 (5/12) cases of liver tissues with CMV infection and 5 cases each with mycobacterium and Toxoplasma gondii infection. Capsid protein p24 was detected in liver tissues in 3 cases.

CONCLUSIONThere is HIV infection in liver tissue of patients with HIV. The rate of opportunistic infections in liver biopsy samples was lower than that in the autopsy liver tissues of patients with HIV.

OBJECTIVETo establish a favorable formula of estimation adult standard liver volume (SLV) based on the data of living donors for liver transplantation.

METHODSFrom March 2005 to December 2007, 90 Adult-to-Adult living donor liver transplantation were performed. The donors' anthropometric data of gender, year, body weight and body height was collected prospectively. The total liver volume (TLV) of 90 living donors was measured by computed tomography. The correlation between TLV and several factors including body weight index (BMI) and body surface area (BSA) were analyzed. Then multiple stepwise linear regression analysis was performed and a new equation predicting SLV to improve approximate TLV was determined. TLV was then compared with the estimation standard liver volume (ESLV) calculated using our formula and published formulas in literature previously.

RESULTSAll the subjects had a mean body weight of (62.4 +/- 8.7) kg. The mean total liver volume was (1319.1 +/- 167.0) ml. There were positively correlated between TLV and body weight (BW), which could be expressed in the equation: TLV (ml) = 12.5 x BW (kg) + 536.4 (r(2) = 0.43, P < 0.01). Compared TLV with ELSV, which were calculated using previously published formulas based on the anthropometric data of the 90 subjects, the difference was be statistically significant.

CONCLUSIONA new simple formula is established that might be a more suitable to calculate TLV in Chinese adults.

OBJECTIVETo evaluate the therapeutic effect of comprehensive therapeutic protocol of electroacupuncture combined with active-blood-and-dissolve-stasis herbs and rehabilitation training for cerebral infarction.

METHODSA multi-center randomized controlled trial was done, three hundred and twenty cases were divided into four groups: electroacupuncture combined with active-blood and dissolve-stasis herbs and rehabilitation training group (group A), electroacupuncture combined with rehabilitation training group (group B), herbs combined with rehabilitation training group (group C) and rehabilitation training group (group D), 80 cases in each group. The following two groups of acupoints were used alternatively in electroacupuncture treatment: the first group including Vasomotor Area, Jianyu (LI 15), Biguan (ST 31), Hegu (LI 4) and Taichong (LR 3); the second group including Motor Area, Quchi (LI 11), Yanglingquan (GB 34) and Shenshu (BL 23). 20 mL Xiangdan injection and 250 mL 5% glucose injection or 250 mL 0.9% sodium chloride injection were used by intravenous drip in herbs treatment once a day. The rehabilitation training was performed by the professional physical therapist. Each group was treated with corresponding treatment protocol. The therapeutic effect was evaluated by index of the mortality or disability rate 3 months after the onset of disease. The intention to treat analysis (ITT) was used in data.

RESULTSThe mortality or handicap rate 3 months after the onset of disease of four groups were 17.5% (14/80) in group A, 22.5% (18/80) in group B, 40. 0% (32/80) in group C, and 31.3% (25/80) in group D, respectively. The group A has a best therapeutic effect (vs group C, group D, both P<0.05), and there was no adverse event.

CONCLUSIONThe combined application of electroacupuncture, active-blood and dissolve-stasis herbs and rehabilitation training is a better treatment for cerebral infarction in clinic.

BACKGROUNDBacterial pneumonia in the recipients of liver transplantation (LTX) is a common postoperative complication influencing the prognosis greatly. In this article, the diagnosis and treatment of bacterial pneumonia in 33 LTX recipients are reported.

METHODSFrom February 1999 to January 2003, a total of 103 patients underwent allogeneic LTX at our center; afterwards, a retrospective analysis was made on their postoperative clinical manifestations, including symptoms (expectoration, panting and fever), sign (rale), results of laboratory examinations (white blood cell count and sputum culture of tracheal secretions or pleural fluid culture), and chest X-ray films. The following data of the pneumonia and non-pneumonia groups were collected, and the rank sum test (SPSS 11.0, Wilcoxon's method) was used to analyze the duration of postoperative respirator utilization and the volume of pleural effusion through pleurocentesis or pleural drainage.

RESULTSIn the 103 patients, 33 experienced 53 episodes of bacterial pneumonia during their hospital stay after transplantation, 14 of them (42.42%) had more than three manifestations of the seven mentioned above. The pathogens causing bacterial pneumonia included Pseudomonas aeruginosa (17.48%), Klebsiella pneumoniae (15.53%), Acinetobacter baumannii (10.68%), and Staphylococcus aureus (7.77%). Amilkacin, tienam, ciprofloxacin, vancomycin, etc. were the antibiotics of choice against those bacteria. Acute rejection occurred during the treatment of bacterial pneumonia in 16 patients, and 5 of them died. Wilcoxon's rank sum test of the data indicated that the pneumonia group had longer duration of postoperative ventilator treatment and larger volume of pleural effusion than the non-pneumonia group (P < 0.05).

CONCLUSIONSThe clinical manifestations of pneumonia after LTX might be atypical, and special attention should be paid to the respiratory symptoms and signs within 2 months after LTX. Whenever the diagnosis of bacterial pneumonia is confirmed, consideration should be given to reasonable use of antibiotics and regulation of immunity in addition to other routine therapies.
