OBJECTIVETo investigate the feasibility of transferring p21 gene into lung tissue with recombinant adenovirus with full-length cDNA of p21 inserted in the Wistar rat model of pulmonary hypertension (PAH) induced by left-to-right shunt, study the expression of the desired gene in vivo, find if overexpression of desired gene can inhibit pulmonary hypertension.
METHODSWith full-length cDNA of p21 transfected HEK293 cells with clonfectin, and was packed, amplified in order to obtain the high-titer recombinant adenovirus (AdCMV-p21). The infection titer was determined by TCID50 method and was diluted into 1.67 x 10(8) pfu/L. Wistar rats were randomly allocated to control group (n = 10), model group (n = 15), test group (n = 10) and test control group (n = 10). In model group and test group left-to-right shunt pulmonary hypertension was developed by using cuff technique. AdCMV-p21 was transfected into test group and test control group using tracheal inhalation. The mPAP, mRVP and RVHI were measured and compared between every two groups. The left lung was immunohistochemically stained to observe the result of transfection. The right lung was HE stained to observe morphological changes in arteria pulmonalis and calculate WT%.
RESULTSThe mRVP, mPAP and WT% in model group and test group were significantly higher than those in control (P < 0.05), which suggested that the rat model of PAH was established successfully. Brown spots in the nucleus of VSMCs of pulmonary artery were seen in test group and test control group, which indicated that AdCMV-p21 was transfected successfully. The rate of transfected cells in test group was (42.8 +/- 11.6)%, which was equal to that of test control group (P > 0.05). In test group, the mPAP was (20.06 +/- 3.40) mm Hg (1 mm Hg = 0.133 kPa), mRVP was (22.53 +/- 2.53) mm Hg, WT% was (30.8 +/- 3.5)%, which were significantly lower than those in model group (P < 0.05), but higher than those in control group and test control group (P < 0.05).
CONCLUSIONThe recombinant adenovirus could successfully carry p21 and transfect the lung tissue of PAH rat model, and full expression of p21. p21 gene could inhibit the development of PAH.

OBJECTIVETo evaluate the efficacy and safety of thrombopoietin (TPO) on platelet engraftment in hematological malignancies patients after allogeneic haematopoietic stem cell transplantation (allo-HSCT).
METHODSOne hundred and twenty patients were enrolled in a multicenter, open-label, randomized, controlled clinical trial, and were randomized into 4 treatment groups following allo-HSCT. Group A was the control arm without TPO, while group B, C and D were trial arms with received 300 U×kg(-1)×d(-1) of TPO starting from day +1, +4 and +7, respectively. A total of 89 cases were evaluated, of which 22 cases in group A, 23 in group B, 20 in group C and 24 in group D. Efficacy evaluation (the time of platelet engraftment, the number of platelet transfusion) and safety evaluation \[adverse events, routine blood tests, liver and renal function, coagulation function and occurrence of graft-versus-host disease (GVHD)\] were observed.
RESULTSThe median platelet engraftment time in experimental groups (groups B, C and D) were on day (13.17 ± 2.89), day (12.15 ± 2.08), day (12.33 ± 1.76), respectively, and that in control group was on day (14.82 ± 5.05). There was statistically significant difference between two groups (P = 0.029), There were no statistically significant difference in the average amount of platelet transfusion, platelet engraftment time, and platelet nadir value among the 3 experimental groups. No significant adverse events were observed in experimental groups.
CONCLUSIONSTPO administration following allo-HSCT for patients with hematologic malignancies appears to shorten platelet engraftment time. TPO given starting from day +7 is effective and safe.

Liver cancer is a common malignant tumor in China and a major health concern. We aimed to estimate the liver cancer incidence and mortality in China in 2010 using liver cancer data from some Chinese cancer registries and provide reference for liver cancer prevention and treatment. We collected and evaluated the incidence and mortality data of liver cancer in 2010 from 145 cancer registries, which were included in the 2013 Chinese Cancer Registry Annual Report, calculated crude, standardized, and truncated incidences and mortalities, and estimated new liver cancer cases and deaths from liver cancer throughout China and in different regions in 2010 from Chinese practical population. The estimates of new liver cancer cases and deaths were 358,840 and 312,432, respectively, in China in 2010. The crude incidence, age-standardized rate by Chinese standard population (ASR China), and age-standardized rate by world standard population (ASR world) were 27.29/100,000, 21.35/100,000, and 20.87/100,000, respectively; the crude, ASR China, and ASR world mortalities were 23.76/100,000, 18.43/100,000, and 18.04/100,000, respectively. The incidence and mortality were the highest in western regions, higher in rural areas than in urban areas, and higher in males than in females. The age-specific incidence and mortality of liver cancer showed a rapid increase from age 30 and peaked at age 80-84 or 85+. Our results indicated that the 2010 incidence and mortality of liver cancer in China, especially in undeveloped rural areas and western regions, were among high levels worldwide. The strategy for liver cancer prevention and treatment should be strengthened.

OBJECTIVETo investigate the protective effect of the roots of F. hirta against the cocaine-induced hepatotoxicity and it's active components.
METHODCocaine hydrochloride was subcutaneously injected to make male ICR mice liver wounded. Male ICR mice were randomly ig administered with the F. hirta decoction. The dose groups are 100, 200, 300 g x kg(-1) herb materials per body weight. Cocaine hydrochloride was subcutaneously injected into the mice after the administration. The serum ALT, AST activity and the activity of CAT in liver homogenate were assayed, and liver change of pathomorphism was evaluated to prove the effect of the F. hirta decoction on cocaine-induced hepatotoxicity. And the activity of psoralean which was separated from the F. hirta decoction by bioassay-guided fractionation, was proofed in the same method.
RESULTWe find that the F. hirta decoction shows a distinct effect on reducing serum transferase. The serum transferase and the content CAT in liver homogenate were dose-related reduced, and the histopathological examination found a significantly change of the liver tissues. And the psoralean, qua the mainly component, shows the same effect.
CONCLUSIONF. hirta has the protective effect against the cocaine-induced hepatotoxicity. Psoralean is the basis.
