OBJECTIVETo investigate the clinicopathological features, diagnosis, treatment and prognosis of primary clear cell carcinoma of the liver (PCCCL).
METHODSThe clinicopathological data of 24 cases with pathologically proven PCCCL in the First Affiliated Hospital of Guangxi Medical University from May 1996 to December 2003 were collected and analyzed.
RESULTSThere were 21 males and 3 females in this group, with an average age of 46 years (range: 30 approximately 78 years). HBV infection was detected in 83.3%, and AFP expression was found in 75.0% of them. Of the 24 cases, 28 tumors were found with an average size of (6.64 +/- 5.54) cm. Liver cirrhosis was found in 75.0% of the patients. Macroscopic and microscopic tumor thrombi were found in 20.8% and 29.2%, respectively. Lymph node metastasis was found in 4.2% of the patents. The 1-, 3-, and 5-year overall survival rates of the 24 cases were 75.0%, 41.7% and 27.8%, respectively, with a median survival time of 29 months.
CONCLUSIONThe clinical characteristics of primary clear cell carcinoma of the liver are similar to that of common hepatocellular carcinoma. It is difficult to be diagnosed preoperatively and final diagnosis depends on pathological examination. Surgical resection is an effective way to achieve favorable treatment outcome and even long-term survival.

OBJECTIVETo study the distribution of aldehyde dehydrogenase-2 (ALDH2) polymorphisms between healthy Zhuang and Han ethnic individuals in Guangxi Autonomous Region and its influence to the behaviors of alcohol consumption.
METHODSPolymerase chain reaction with confronting two-pair primers (PCR-CTPP) and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) techniques were used to genotype ALDH2, respectively, and alcohol consumption was recorded in a constructed questionnaire.
RESULTSThe frequencies of ALDH2 alleles (ALDH2(1)/ALDH2(2)) among Zhuang and Han ethnics were 0.511, 0.489 and 0.508, 0.492 respectively (chi2 = 0.001, P > 0.05). The ALDH2 genotypes were verified with PCR-RFLP method. The frequencies of ALDH2(1) genotype in alcoholics (> or = 3 times drinking per week) were 35.59% and 15.67% in Zhuang and Han groups respectively (chi2 = 5.800, P = 0.016).
CONCLUSIONThere was no significant different distribution of ALDH2 genotype among healthy Zhuang and Han ethnic people. The genotype of ALDH2 in different ethnicity might influence individual behavior of alcohol consumption.

BACKGROUND AND OBJECTIVEMultinodular hepatocellular carcinoma(HCC) might originate from multicentric occurrence (MO) or intrahepatic metastasis(IM). This study was to find out proteins which play important roles in clonal origin of multinodular hepatocellular carcinoma bt screening the differentially expressed proteins between the MO and IM tissues using comparative proteomic analysis.
METHODSTotal protein extracted was separated by two-dimensional gel electrophoresis. Comparative analyses of the 2-DE protein patterns between the two groups were carried out using computerized imaging techniques. Proteins exhibiting significant alternations were subsequently isolated and identified by mass spectrometry.
RESULTSA total 1025+/-52 and 900+/-98 spots were detected in the protein profile in IM and MO, respectively. Twenty-five protein spots were statistically different at expression levels between the two groups. Twenty of them were identified by MALDI-TOF-MS and bioinformatics.
CONCLUSIONSThe protein profile of MO HCC tissues is different from that in IM HCC tissues. The twenty differentially expressed proteins might play a key role in the carcinogenesis and progression of multinodular HCC. These newly identified proteins might be potential and valuable biomarkers for identifying the multinodular HCC of clonal origin.

BACKGROUND:
Butylphthalide (NBP) and edaravone (EDV) injection are common acute ischemic stroke medications in China, but there is a lack of large real-world safety studies on them. This study aimed to determine the incidence of adverse events, detect relevant safety signals, and assess the risk factors associated with these medications in real-world populations.
METHODS:
In this study, data of acute ischemic stroke patients were extracted from the electronic medical record database of six tertiary hospitals between January 2019 and August 2021. Baseline confounders were eliminated using propensity score matching. The drugs' safety was estimated by comparing the results of 24 laboratory tests standards on liver function, kidney function, lipid level, and coagulation function. The drugs' relative risk was estimated by logistic regression. A third group with patients who did not receive NBP or EDV was constructed as a reference. Prescription sequence symmetry analysis was used to evaluate the associations between adverse events and NBP and EDV, respectively.
RESULTS:
81,292 patients were included in this study. After propensity score matching, the NBP, EDV, and third groups with 727 patients in each group. Among the 15 test items, the incidence of adverse events was lower in the NBP group than in the EDV group, and the differences were statistically significant. The multivariate logistic regression equation revealed that NBP injection was not a promoting factor for abnormal laboratory test results, whereas EDV had statistically significant effects on aspartate transaminase, low-density lipoprotein cholesterol and total cholesterol. Prescription sequence symmetry analysis showed that NBP had a weak correlation with abnormal platelet count. EDV had a positive signal associated with abnormal results in gamma-glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, prothrombin time, and platelet count.
CONCLUSIONS
In a large real-world population, NBP has a lower incidence of adverse events and a better safety profile than EDV or other usual medications.
