The paper reviewed and analyzed the literature in the past five years about the function of the cells and mediums in the liver, and the influence and mechanism of traditional Chinese drug therapy on experimental liver fibrosis. It reveals that the traditional Chinese drug therapy treats experimental liver fibrosis through lots of mechanisms. The author gives also some suggestions on the further research into liver fibrosis.

Pulmonary hypertension has now become a common diseases threaten to human health .There are many factors that can cause pulmonary hypertension , such as heredity, immune injury, inflammation and endothelial function damage , etc.In recent years, studies have found that patients with pulmonary hypertension commonly have the phenomenon of iron deficiency , and intravenous iron agent can improve that , but the specific mechanism is unclear .Iron in the human body mainly is controlled by a protein called hepcidin, it inhibits iron flow from the gastrointestinal to the blood .Thus, intravenous iron administration can provide new options for the treatment of pulmonary hypertension .This paper reviews the progress of the iron deficiency and pulmonary hypertension .

Objective To enrich breast cancer stem cells of breast cancer cell lines MCF-7 and MDA-MB-231 through culturing mammospheres,and to detect the expression differences of gene of breast cancer stem cells makers.Methods The MCF-7 and MDA-MB-231 cell lines were cultured by serum and serum-free medium.The proportion of CD44+/CD24-and CD133+ cancer stem cells was measured in cells derived from mammosphere cells or monolayer culture cells by flow cytometry,and the expression of CD44,CD24,CD133,ALDH3A1,ABCG2 and CXCR4 mRNA were detected by RT-PCR.Results Flow cytometry analysis indicated that the CD44+/CD24-low proportion of the MCF-7 mammosphere cells was higher than its adherent culture cells (P ＜ 0.05),and CD133+ proportion had no difference between them (P ＞ 0.05).However,the CD44+/CD24-/low proportion of the MDA-MB-231 mammosphere cells was lower than its adherent culture cells (P ＜ 0.05),while CD133+ proportion was significantly higher than its adherent cultured cells (P ＜ 0.05).RT-PCR analysis suggested that the expression of CD44 and ABCG2 increased obviously in MCF-7 microspheres (P＜ 0.05),and the expression of CD24,CD133,ALDH3A1 and CXCR4 had no significant difference between the mammosphere cells and adherent culture cells (P ＞ 0.05).The CD24,CD133,ABCG2,ALDH3A1 and CXCR4 increased obviously in MDA-MB-231 microspheres.On the contrary,the CD44 decreased (P ＜ 0.05).The expression of CD44 and CD24,CD133 and ALDH3A1 had significant differences in the microspheres of MCF-7 and MDA-MB-231 cells (P ＜ 0.05).Conclusion The related cancer stem cells gene expression is different in the microspheres of human breast cancer cell line,which indicates that the different subtypes of breast cancer may be derived from different origins.

Objective To explore the significance of serum cytokine interferon-gamma (IFN-γ) ,interleukin-4(IL ) ,transforming growth factor-beta 1 (TGF-β1) ,interleukin-9 (IL-9) ,interleukin-17 (IL-17) in detection of youth first-episode depression .Methods Ninety cases of youth first-episode depression as the experimental group were equally divided into 3 groups according to different disease courses(<6 months ,6 months to 2 years ,>2 years)and other 30 normal persons served as the control group .The levels of serum cytokines were measured by ELISA .The level of each cytokine and Hamilton Depression Scale (HAMD) score were per-formed the Spearman correlation analysis .Results The IL-9 level in the 6 months to 2 years group and > 2 years group was high-er than that in the control group (P< 0 .05);the IFN-γlevel was negatively correlated with psychic anxiety (P<0 .05);the IL-9 level was positively correlated with the somatic anxiety and systemic symptoms (P<0 .05);the IL-17 level was positively correla-ted with the depressive mood and suicide (P<0 .05);the IFN-γlevel was positively correlated with difficulty falling asleep ,early a-wakening ,work and interest in the 6 months to 2 years group ,while positively correlated with somatic anxiety (P<0 .05);the IFN-γ level was positively correlated with depressive mood and block in the >2 years group(P<0 .05);the IL-4 level was positively correlated with the depressive mood (P<0 .05) .Conclusion Different cytokines play different roles in youth first-episode depres-sion ,cytokines may involve in the occurrence and development of depression .

Repeated administrations of gangliosides extracted from Cervus nippon Temminek exerted remarkable facilitation action on the acquisition, retrieval and consolidation of memory in mice. It was able to increase the incorporations of [8H] Leucine into protein and [3H] Uridine into RNA in mouse brain tissue. It was suggested that the above-mentioned actions of gangliosides may be due to the promoting action for the synthesis of protein in brain tissue.

The expression of human epidermal growth factor (hEGF) and hEGF receptor (hEGF-R) was examined by 125I-labeled-hEGF binding analysis in 21 cases of colonic carcinomas. No significant difference was found in the values of hEGF binding among carcinoma, paracarcino-ma regions and regions far away from carcinoma, but the values in all of them were higher than that in normal colonic tissues (P

Objective To sum up the experience of perioperative management of patients with heart transplantation.Methods In recent 3 years 24 cases of dilated cardiomyopathy,4 cases of(serious) valve disease,1 case of serious ischemic cardiomyopathy and 1 case of bi-ventricular assist(received) heart transplantation surgery.The mean by pass time was 75?24 min and the mean aortic clamp time was 72?8 min.Cyclosporine,MMF and prenisodone were adopted as anti-immune(response) strategy and the dose of cyclosporine was adjusted according to the serum concentration.(Intramyocardial) electrograms and tissue Doppler ultrasound technique were used to monitor the(immune) response situation.The myocardial biopsy was performed in case of the suspect of acute(rejection).Results In 5 postoperative deaths,3 cases died of low cardiac output,1 died of infection-(induced) multiple organ failure and 1 case died of serious bleeding.The postoperative complications(included) right heart failure in 6 cases,renal failure in 13 cases,and acute rejection in 4 cases.(Conclusion) The effective prevention and management of complications is the key point of success of heart transplantation.Application of comprehensive monitoring techniques is beneficial to the management of the immune rejection after transplantation.

Aim To observe the effect of dopamine (DA) and its antagonist on the electrical activities of pain excitation neurons (PEN) in the caudate nucleus (Cd) of morphine dependent rats. Methods The right sciatic nerve was stimulated by train of electrical impulses as noxious stimuli to morphine dependent rats.The electrical discharges of PEN in Cd were recorded with glass microelectrode to observe influences of intracerebroventricular (icv) injection of DA and droperidol on the electrical activities of PEN. Results DA could decrease excitabilities of PEN in Cd of morphine dependent rats. Conclusion Results suggest that the depression of DA on PEN response in Cd of morphine dependent rats might be blocked by droperidol.

AIM: To investigate the clinic efficacy and operation safety of improved small incision extracapsular cataract extraction in the sight-regaining program.
METHODS: Totally 82 cases ( 82 eyes ) included in the sight-regaining program of the cataract patients were underwent small incision extracapsular cataract extraction conbined with improved technology ( anterior capsule staining, continuous curvilinear capsulorhexis, auxiliary incision ) , postoperative visual recovery and operative complications were observed.
RESULTS: Postoperative visual acuity: uncorrected visual acuity when out of hospital: ≥0. 3 were 67 cases (82%);1wk after dismissed from hospital:≥0. 3 were 76 cases (93%), admist which ≥0. 8 were 45 cases (55%). There is no serious complication such as posterior capsule rupture, zonular dialysis, etc. in the operation.CONCLUSION: Combined use of improved technology can increase operation safety of small incision extracapsular cataract extraction.
