In this study, to investigate the effect on expression of IL-2 in lymphocytes from bone marrow and peripheral blood of normal donors after they were mobilized by G-CSF in allo-BMT, 7 normal donors bone marrow and peripheral blood were harvested before and after G-CSF administration. The separated lymphocytes were measured by FCM after they were stained intracellularly by anti-IL-2, and their expressions of IL-2 were compared. The degree of aGVHD in patients after bone marrow transplantation was evaluated clinically, and it was compared with the status of aGVHD of 15 patients whose donors didn't receive G-CSF administration in our department, and 2 groups of patients are comparable in age, types of diseases and status of donors. The results showed that the expression of IL-2 in lymphocytes in 7 G-CSF mobilized donors decreased significantly after G-CSF administration and more severe aGVHD than grade II didn't develop in these recipient patients, and comparing with 15 patients received the bone marrow from donors who didn't receive G-CSF, the incidence of aGVHD decreased. It is suggested that the expression of IL-2 in lymphocytes was influenced by donors' G-CSF administration, and it is likely that thereby reduces the incidence of aGVHD in patients after BMT.

OBJECTIVETo investigate the risk factors of lung cancer in Tianjin and to provide evidence for further monitor there of.

METHODSA case-control study involving interviews with 193 new cases and 259 controls aged 30 - 76 years was carried out. Structured questionnaires were used to collect information on general condition, living environment, living style, disease and family history, etc. Logistic regression model univariate and multivariate analysis were used to pick out the significant lung cancer risk factors.

RESULTSBy monovariate analysis, risk factors such as smoking, passive smoking, drinking, history of malignancy in family and occupation were found. By multivariate analysis, smoking, passive smoking, higher body mass index (BMI) and average income and living space per capita ten years earlier were ascertained, their operations research (OR) values were 3.302, 1.193, 1.003, 1.067 and 0.913.

CONCLUSIONSmoking and passive smoking are independent risk factors of lung cancer. Monthly income per person and living space per person 10 years earlier are associated with elevated risk of lung cancer. Higher body mass index has protective effects on lung cancer risk.

OBJECTIVETo investigate the efficacy and safety of secreted interferon in treatment of chronic hepatitis B.

METHODSA multi-center randomized open-label controlled clinical trial was carried out. The patients of the study group were treated by secretory human interferon alpha-2a, and the patients of the control group were treated with an ordinary interferon.

RESULTSALT normalization rate in the secreted interferon group was 48.3% and it was higher at the end of treatment than that of the control group, but there was no difference between the two groups at the end of the follow-up. HBV DNA dropped more in the study drug group, but there was no difference in the normalization rate between the two groups. HBeAg seroconversions in secreted interferon group and in the control interferon group were 19.0% and 18.4% respectively. The safety of the two types of interferon was satisfactory.

CONCLUSIONSSecreted interferon was superior to ordinary interferon in ALT normalization and HBV DNA drop at the end of treatment in chronic hepatitis B patients, but there was no difference at the end of the follow-up. There was also no difference in HBeAg negative and HBeAg seroconversion between the two groups.

A sensitive, rapid and specific liquid chromatographic-tandem mass spectrometric (LC-MS/MS) method for quantification of gabapentin in human plasma has been developed. After a single plasma protein precipitation with methanol, gabapentin and metformin (internal standard) were chromatographed on a Inertsil ODS-3 column (50 mm x 2.1 mm ID, 3 microm) with mobile phase consisting of methanol-0.2% formic acid aqueous solution (80:20, v/v) at a flow-rate of 0.2 mL x min(-1). Electrospray ionization (ESI) source was applied and operated in the positive ion mode. Multiple reaction monitoring (MRM) mode with the transitions of m/z 172 --> m/z 154 and m/z 130 --> m/z 71 were used to quantify gabapentin and metformin, respectively. The run time was 2.2 min. The linear calibration curve was obtained in the concentration range of 40.8-8.16x10(3) ng x mL(-1). The lower limit of quantification was 40.8 ng x mL(-1). The intra- and inter-day precision (RSD) was less than 12%, and the accuracy (RE) was within +/-6.4% calculated from quality control (QC) samples. The method was used to determine the concentration of gabapentin in human plasma after a single oral administration of 600 mg gabapentin capsule to 20 healthy male Chinese volunteers. The method was proved to be selective, sensitive, rapid and suitable for pharmacokinetic study of gabapentin in human plasma.

OBJECTIVETo study the levels of prevalence and to describe the epidemiological features of birth defects in high-prevalence areas in China.

METHODSA population-based retrospective study was conducted in two counties of Shanxi province that including birth defects among fetuses and live births born after 20 weeks' gestational age in the study areas from 2002 through 2004.

RESULTSDuring 2002 - 2004, the prevalence of birth defects was 844.2 per 10 000 births in study areas and the first five main birth defects were inguinal hernia (182.2 per 10,000 births), anencephaly (104.4 per 10 000 births), congenital mental retardation (79.4 per 10,000 births), congenital heart diseases (73.2 per 10,000 births) and spina bifida (63.9 per 10,000 births). These five main birth defects accounted for about 60% of total birth defect cases. Inguinal hernia, undescended testicle, congenital mental retardation were usually not included for statistical analysis on birth defect. Excluding these birth defects, the prevalence of birth defects in study areas was 537.2 per 10,000 births and the first five main birth defects were anencephaly, congenital heart diseases, spina bifida, hydrocephaly (40.5 per 10 000 births) and encephalocele (31.2 per 10 000 births). The male prevalence of birth defects was 966.2 per 10 000 births, which was significantly higher than prevalence in females. The prevalence rates of birth defects for maternal age groups under 20 years old and over 30 years old were remarkably higher than those for 20-24 year and 25-29 year old mothers. The teenage mothers were at higher risk of having a child with neural tube defects(NTDs) or congenital heart diseases. Prevalence rates under 20 year maternal age group were 408.8 and 188.7 per 10 000 births for NTDs and congenital heart diseases respectively, whereas corresponding rates were 204.8 and 91.0 per 10 000 births for groups over 30 years of age. The prevalence rates increased with increasing gravidity or parity.

CONCLUSIONThis study showed that the patterns of birth defects in study areas were very different from those of other areas, with an unusually high prevalence of NTDs. The study also suggested that both young and advanced mothers were at increased risk of having a child with a birth defect.

OBJECTIVETo evaluate the mRNA and protein expressions of peroxiredoxin II (PrxII) in hepatocellular carcinoma (HCC) and their significance.

METHODSHCC was induced by aflatoxin B1 (AFB1) in 6 tree shrews (Tupaia belangeri chinensis). The expression levels of PrxII mRNA and protein were detected by reverse transcriptase polymerase chain reaction (RT-PCR) and Western blot on HCC tissues and on their surrounding liver tissues (para-HCC). Biopsied liver tissues were taken before the HCC induction (pre-HCC) from the same animals and from a group of blank controlled animals that served as controls. Liver biopsy specimens from 18 cases of human HCC and from 17 healthy human volunteers were studied using the same methods.

RESULTSThe mRNA and protein expressions of PrxII in tree shrew HCC tissues were significantly higher than those in para-HCC and pre-HCC tissues, and also higher than those in the liver tissues from the control animals (all P < 0.05). The expression levels of PrxII mRNA and protein in human HCC tissues were also significantly higher than those in their para-HCC tissues and in the human normal liver tissues (P < 0.05).

CONCLUSIONPrxII might play an important role in hepatocarcinogenesis and might be used as a molecular target for HCC prevention and treatment.

OBJECTIVETo study the effects of umbilical cord blood monocytes (UCBMC) transplantation on erythropoietin (EPO) protein and oligodendrocyte progenitor cells in hypoxia-ischemia (HI) neonatal rats.

METHODSForty seven-day-old Sprague-Dawley rats were randomly divided into normal control (N), HI, UCBMC and HI+UCBMC groups (n=10 each). Hypoxic-ischemic brain damage (HIBD) model was prepared according to the Rice method. Twenty-four hours after hypoxia, the N and HI groups were injected with 2 μL phosphate buffered saline (PBS), and the UCBMC and HI+UCBMC groups were injected with 3×10(6) UCBMC via the lateral ventricle. EPO protein and oligodendrocyte progenitor cells in the subventricular zone of the injured brain were observed by EPO/DAPI and NG2/DAPI immunofluorescence double staining, and their correlation was analyzed.

RESULTSSeven days after transplantation, there were more NG2(+)DAPI(+) and EPO(+)DAPI(+) cells in the HI+UCBMC group than in the UCBMC (P<0.05), N and HI groups (P<0.01). More NG2(+)DAPI(+) and EPO(+)DAPI(+) cells were observed in the UCBMC group compared with the N and HI groups (P<0.01). There were more NG2(+)DAPI(+) cells in the N group than in the HI group (P<0.01). The number of NG2(+)DAPI(+) cells was correlated with the number of EPO(+)DAPI(+) cells in the HI+UCBMC group (r=0.898, β=1.4604, P<0.01).

CONCLUSIONSUCBMC can promote expression of oligodendrocyte progenitor cells, which is correlated with an increase in EPO protein and thus repairs brain white matter damage in neonatal rats with HIBD.

OBJECTIVETo uncover the transmission patterns of the HIV epidemic in Dehong prefecture.

METHODSThe reviewed case reports, data of sentinel surveillance, testing and special survey were analyzed by SAS 8.0 program. The transmission patterns were modeled by utilizing data including sizes of the whole population and the high risk groups, high risk behavior data from 1989 to 2007, and the population index such as sex ratio and fertility rate.

RESULTSIn 2005, case reports showed the proportion of people infected with HIV through sexual contact was 39.1%, and 46.9% in 2006. Among 1636 cases reported between January 1 to September 20, 2007, the proportion of people infected with HIV through sexual contact was 52%. From 1989 to 2007, the proportion of HIV infection among drug users was declining, while HIV infection through sexual contact was rising after standardizing the population tested/surveyed. The Asian Epidemic Model has shown that the proportions of incident HIV infections through sexual transmissions were 50.6%, 52.3% and 52.7% respectively from 2005 to 2007. Correspondingly, the proportions of incident cases by injecting drug user were 48.9%, 47.2% and 46.7% respectively during this period. Moreover, the Workbook method has shown that, among adults living with HIV in 2007, 50.3% were infected through injecting drugs and 48.4% through unsafe sexual activity.

CONCLUSIONThe rapid rise in HIV infections through injecting drug in Dehong prefecture has been initially curbed. HIV epidemic has already witnessed a change from predominantly through drug injecting-related activity to an almost equally fuelled epidemic by sexual and drug-related transmission.
