BACKGROUND:Lycium barbarum polysaccharide, the main active component of leaves of lycium barbarum, has a remarkable therapeutic effect on osteoporosis in adult ovariectomized female rats.
OBJECTIVE:To explore effects of leaves ofLycium barbarum on serum estradiol and bone estrogen receptor expressions in adult oxariectomized female rats.
METHODS: Thirty-two 6-month-od female rats were randomized into sham-surgery, model, and treatment groups, respectively. Rat models of postmenopausal osteoporosis were induced by ovariotomy folowed by oraly administration of water solution of leaves ofLycium barbarum (500 or 1 000 mg/kg) or distiled water once daily for consecutive 12 weeks in treatment and model groups, respectively. Serum estradiol level was detected by radiation immunoassaymethod. Estrogen receptor α, β immunoreactivities in bone tissue were determined by immunohistochemical staining.
RESULTS AND CONCLUSION:Serum estradiol level in the model group was significantly decreased compared with the sham-surgery group (P < 0.01), but that was significantly increased in the treatment groups, particularly at high dose, compared with the model group (P< 0.01). Estrogen receptor α, βimmunoreactivities were weaker in the model group than the sham-surgery group (P < 0.01), and those were stronger in the treatment groups than the model group (P < 0.01). Our results suggest that leaves of Lycium barbarum treat osteoporosis through enhancing serum estradiol and estrogen receptor expressions in adult ovariectomized rats.

0.05). However, compound muscle action potential (CMAP) amplitude in ims injected group wa s si gnificantly higher as compared with the other two groups[ims injected group (12.50?2.06) mV, iv group (1.50?0.20) mV, control group (10.13?4.04) mV, F=6.347, P=0.033].

The atrophy of gastrocnemius in ims injected group was much less severe than that of the other 2 groups. The diameter of muscle fibers was significantly longer on d60 (F=4.537,P=0.021).Conclusion:Intra- muscular injection of MSC was well distributed in denervated muscle, which provides a newway of nerve regeneration in the rat model of sciatic nerve injury.

Objective To detect and analyze the levels of preoperative serum carcino-embryonic antigen (CEA) and CA15-3 in early invasive breast cancer patients and their correlation with pathological parameters. Methods Electrochemical luminescence immunoassay (ECLI) technology was used to detect serum levels of CEA and CA15-3 in 223 cases of early invasive breast cancer patients, 109 patients with benign lesions, and 30 cases of heath control. Immunohistochemical (IHC) and fluorescence in situ hybridization (FISH) were used to detect the estrogen receptors (ER), progesterone recepter (PR), and its HER-2 pathological indicators.Besides, the correlation of serum CA15-3, CEA levels and pathological parameters was analyzed. Results The serum CA15-3 and CEA levels of Breast cancer patients [(22.27±15.11) U/ml, (5.03± 0.49) μg/L] were significantly higher than that of patients in benign lesion group [(14.13±3.04) U/ml, (2.72± 0.11) μg/L] (P< 0.05). CEA level of patients with histological grade Ⅲ was (6.34 ±0.93) μg/L, significantly higher than the level Ⅰ-Ⅱ (4.23±0.50) μg/L (P< 0.05). CA15-3 level was (19.26±15.08) U/ml in T1 tumors, and CA15-3 level was (28.73 ±11.53) U/ml in T2 tumors (P<0.05). The serum levels of CEA and CA15-3 between different histology, pathologic stage, lymph node status, ER, PR, HER-2, pathological characteristics had no significant difference (P>0.05). CEA positive rate of breast cancer group was significantly higher than that of benign lesions(13.5%vs. 3.7%, 26.5%vs. 1.8%, P<0.05). 30 cases of normal control group had no positive one. The joint monitoring sensitivity of CEA and CA15-3 breast cancer group was 9.4 %, the sensitivity was 0 in benign lesion group. There was significant difference (P < 0.05). Conclusion The changes of Serum CA15-3 and CEA levels in breast cancer patients can be considered as the judgment standard for early diagnosis, pathological staging, prognosis and clinical effect monitoring.

Abstract： Objective To evaluate the filtration effects of various nanofiltration systems on intravenous human immunog⁃ lobulin（IVIG）in order to screen the optimal nanofiltration system. Methods Various nanofilters were used for IVIG filtration to determine the best one and then various prefilters were selected to combine with the optimal nanofilter for IVIG filtration to determine the optimal nanofiltration system. Results The tangential flow（cross flow）nanofilter showed better filtering effect than dead end（direct current）nanofilter，and nanofilter C was the best one. The effect of deep filtration prefilter was better than that of absolute filtration prefilter，and prefilter Y1 in series with nanofilter C was the optimal nanofiltration system. Conclusion The optimal nanofiltration system was determined through the effect evaluation of various nanofiltration systems filtering for IVIG.

ObjectiveTo evaluate the feasibility and efficacy of ex-vivo liver resection combined liver autotransplantation for patients with massive primary liver cancer who underwent complex liver resection.Methods The clinical data of 4 patients suffering from massive primary liver cancer who were admitted to the Beijing Chaoyang Hospital from January 2008 to May 2010 were retrospectively analyzed.Regular liver resection could not be carried out because the first,second and third hepatic hilum of the 4 patients were invaded by the tumors,so ex-vivo liver resection combined liver autotransplantation were performed.ResultsThe operation was successfully carried out for the 4 patients.The operation time,the duration of anhepatic phase and the volume of operative blood loss were 690-840 minutes,250-300 minutes and 400-1400 ml,respectively.Portacaval bypass operation was not performed.After ex-vivo liver resection,the inferior vena eava or hepatic vein and portal vein of the 4patients were repaired,and the allogenous blood vessels were kept to extend the superior vena cava of the remnant liver so as to facilitate the anastomosis of blood vessels and reconstruction of the first hepatic hilum. After operation,the hepatic function of 1 patient was back to normal; 1 patient who stfffered from abdominal hemorrhage received reoperation for hemostasia; 1 patient was found with hepatic dysfunction; 1 patient died of hepatorenal dysfunction at postoperative day 5.Compensatory hypertrophy was observed in the 3 patients who survived at postoperative months 1-2.Of the 3 patients,2 were found with multiple pulmonary metastases at postoperative months 8 and 9,and they died at postoperative mouths 13 and 15.Until April 2012,1 patient survived for 37 months with no tumor recurrence or metastasis. ConclusionsEx-vivo liver resection combined liver autotransplantation provides the technical feasibility for performing complex liver resection for patients. The incomplete compensation of liver function and the short-term recurrence of tumors after operation are still the main issues which hinder the development of this technique.

Objective To identify a aldehyde dehydrogenases positive (ALDH+) cancer stem cell subpopulation in MCF-7 cells and to investigate the proliferation and differentiation characteristics of these cells in vitro.Methods ALDH+ breast cancer stem cells were isolated from MCF-7 cells by flow cytometry and the biological property of ALDH+ breast cancer stem cells were examined by scarification test,MTT,growth curvature and Transwell migration assay.Results The ratio of CD-/low24 CD+44 cells was about 1.4 ％ in MCF-7 cells.The ratio of ALDH+ CD-/low24CD+44 cells was about 1.2 ％.The growth curvature of ALDH+ breast cancer stem cells was almost the same with that of CD-/low24 CD+44 cells.The distance between cells was obviously shorter in both CD-/low24 CD+44 cells scarification zone and ALDH+ CD-/low24 CD+44 cells scarification zone.The migration ability of CD-/low24CD+44 cells and ALDH+ CD-/low24CD+44 cells was stronger than control group cells.There were migration ability differences between CD-/low24CD+44 cells and ALDH+ CD-/low24CD+44 cells.The results of Transwell experiments were in coincidence with above results.Lots of CD-/low24CD+44 cells and ALDH+ CD-/low24CD+44 cells were through the membrane.In MTT assay,absorbance values were 1.05±0.098,1.56±0.075 and 1.67±0.032.Conclusion CD--/low24CD+44 and ALDH+ CD-/low24CD+44 breast cancer stem cell subpopulation exist in MCF-7 cells.ALDH could potentially be used as a molecular marker to identify breast cancer stem cell subpopulation.

Objective To study the correlation of HBV infection pretransplantation and posttrans-plantation and HCMV recurrence after liver transplantation (LT). Methods We reviewed historical patient medical records of LT patients in recent two years in our hospital. All the patients were divided into HBV in-fection group and a control group based on a peripheral blood HB antigen assay before LT. The HBV infec-tion group was divided into HBV reactive infection group and HBV non-relapse group. HCMV antigen pp~65 was detected by immunohistochemical methods. HB antigens and antibodies were detected by time-resolved fluorescence immunoassay, and liver enzyme levels were detected by conventional methods. Results Com-paring two groups of patients, pp65-positive rates of LT patients with HBV infection and control group pa-tients were 84.3% and 57.9% respectively (P=0.024). While in HBV recurrence infection group and non-recurrence infection group, the incidences of HCMV recurrence were 90.9% and 83.3% (P=0.843). The changes in the liver transaminases level in both groups have no statistical significance (P>0.05). Conclusion Pretransplantation HBV infection may increase the incidence of HCMV recurrence. Posttrans-plantation HBV reactive infection, however, may not increase the incidence of HCMV reactive infection. Meanwhile, compare with either HBV infection or HCMV infection alone, co-infection may not serious in liv-er enzymes levels.
