Objective To analyze the dynamic changes in blood lipids and ATP-binding cassette transporter A1 (ABCA1) in peripheral blood monocytes of the patients with type 2 diabetes, and explore the correlations between ABCA1 expression and blood lipids levels and glycometabolism. Methods Human monocytes were isolated from the patients with type 2 diabetes (n=40) and from the healthy individuals (n=40) serve as normal control. ABCA1 was labeled by immune reaction PE fluorescence, then the changes in ABCA1 expression before and after being incubated with the ox-LDL were investigated by flow cytometer. The blood lipid levels, fasting plasma glucose (FPG) and glycosylated hemoglobin (HbA1c) levels in the patients of type 2 diabetes group were determined, and the correlations between ABCA1 and age, blood lipid, and glycometabolic levels were analyzed. Results Plasma levels of triglyceride, non-high density lipoprotein cholesterol (NHDL-C) [low density lipoprotein cholesterol (LDL-C) and very low density lipoprotein cholesterol (VLDL-C)] in the patients of type 2 diabetes group were significantly higher than that in control group (P

Objective To evaluate the role of contrast-enhanced ultrasound (CEUS) for preoperative detection of colorectal liver metastases.Methods 42 consecutive patients with colorectal liver metastases confirmed by histopathology after surgery were recruited in the study.They all had undergone preoperative CEUS examination with contrast agent SonoVue.The number,location and size of the hepatic lesions found by CEUS were correlated with postoperatively histopathologic results on a lesion-by-lesion basis.Results 96 liver metastases in 42 patients with colorectal cancer had been resected and confirmed by histophathology.The size of the metastatic lesions ranged from 0.3～8.5 cm [average (2.6 ± 1.8)cm].From one to eight metastatic lesions were detected in one patient.21 (21.9％) metastatic lesions were equal to or less than 1.0 cm.86 of 96 metastatic lesions were correctly depicted by CEUS,with a sensitivity of 89.6％.And the sensitivity for metastatic lesions equal to or less than 1.0 cm was 71.4％ (15 of 21 tumors) by CEUS.35 metastatic lesions were found between the portal venous phase and late phase by CEUS and 19 (54.3％) metastatic lesions among them could not be detected at conventional ultrasound.The curative resection was performed in 37 (88.1％) of 42 patients.With 3 - 39 months follow-up,the intrahepatic recurrence rate within two years was 32.4％ (12 of 37 patients) and the one-year survival rate was 90.0％.Conclusions CEUS is highly sensitive for detecting liver metastases resulted from colorectal cancer,especially for small metastatic lesions.CEUS is helpful to choose reasonable therapeutic strategies and can be regarded as one of the most importantly and noninvasively preoperative imaging modalities.

OBJECTIVE:To discuss the characteristics and regular patterns of adverse drug reactions (ADRs) induced by Qingkailing injection for references of clinical rational drug use. METHODS:ADR cases induced by Qingkailing injection reported in Chinese pharmaceutical journals from 2003 to 2005 were retrieved and analyzed statistically. RESULTS:The ADRs induced by Qingkailing injection were more often seen in men than in women, with children and young adults showing higher percentages. Allergic reactions were the main type of adverse drug reactions. Of the total ADR cases induced by Qingkailing injection, 22 cases(33.33%) were anaphylactic shock,15(22.73%) were allergic reactions,10(15.15%) were allergy of circulation system. CONCLUSION:The ADRs induced by Qingkailing injection may be resulted form many factors, which should be given fully attention in the clinic. ADRs monitoring should be stressed when this drug being used by western medicine physicians to make sure rational use of which and to reduce incidences of ADRs.

OBJECTIVE:To investigate the situation and characteristics of serious adverse drug reactions (ADR) occurred in our hospital in order to promote rational clinical drug use. METHODS: 25 severe ADR cases collected in our hospital from Jun. 2004 to Dec. 2006 were analyzed statistically and evaluated based on the ADR causality judgment criteria. RESULTS: The 25 severe ADR were associated with 21 kinds of drugs, with anti-infectives (12 kinds) making up the highest proportion, followed by traditional Chinese medicine preparations. The main systems involved in he ADR were skin and its appendages and nervous system. 3 new and severe ADR cases were found to have no report in package inserts or literature. CONCLUSION: Severe ADR may be induced by many factors, therefore, it is necessary to strengthen the awareness of rational drug use to guard against severe ADR and ensure safe and effective medication.

Objective;To explore the mechanism ofSimiaosan drug-containing serum on prevention and treatment of renal fibrosis.Methods Human renal tubular epithelial cells (HK-2) were divided into blank group, model group, control group, and drug-containing serum high dosage group, medium dosage group and low dosage group. The expressions of CTGF and BMP-7 were determined by real-time PCR assay and immunocytochemistry.Results After the HK-2 cell was induced by uric acid (UA), the expression of CTGF significantly increased (P<0.05), the expression of BMP-7 significantly decreased (P<0.05). After intervened bySimiaosan, the expression of CTGF significantly decreased (P<0.05), the expression of BMP-7 significantly increased (P<0.05) and present dosage dependent.Conclusion Reducing the expression of CTGF and up-regulation the expression of BMP-7 and controlling epithelial-myofibroblast transdifferentiation may be the mechanism ofSimiaosan on prevention and treatment of renal fibrosis.

Objective To evaluate the role of contrast-enhanced ultrasound (CEUS) on the the detection of hepatic metastases in comparison with conventional ultrasonography (US) and contrastenhanced computed tomography (CECT).MethodsNinety-seven patients with hepatic metastases underwent US,CEUS and CECT images.Their detection of hepatic metastases were compared.Results Hepatic metastases showed five enhancement patterns with CEUS,including bolus hyper-enhancement,peripheralrimenhancement,inhomogeneousenhancementwithnecrosis,hypo-enhancement,isoenhancement with liver parenchyma,all hepatic metastases showed dark defects in portal and delayed phase.The mean number of metastases at CEUS was greater than that of US (2.6±1.9 vs 1.6 ±1.2,P＜0.05).The detection of hepatic metastases was 53.4％ and 87.1％ respectively(P＜0.05).CEUS and CECT have no statistically significant difference in the detection of hepatic metastases (P＞0.05).ConclusionsCEUS can improve detection of hepatic metastases.

ObjectiveTo observe the subcutaneous and intraperitoneal insulin injection's effect of the level of oxygen free radicals of type 2 diabetes model.MethodsC57BL/6J mice were chosen as normal control group (C group,n=9).KK mice were randomly divided into intraperitoneal injection of insulin group (i.p.group,n=9),the subcutaneous insulin group (s.c.group,n=9) and untreated group (U group,n =9).The i.p.group and the s.c.groups were given certain amount of insulin (insulin injecta and protamine insulin injecta by volume ratio of 2:1 mixture)for one month,maintained the GLU at normal levels (6±1.5) mmol/L.SOD,GSH-PX activity and MDA content of serum,liver,kidney and heart in each group were detected.Results The liver,kidney,heart and serum's SOD and GSH-PX activity significantly reduced and MDA content significantly increased in the U group.Both kinds of delivery methods could increase serum SOD and GSH-PX activity and reduce the content of MDA to the normal control group level,but the intraperitoneal injection had stronger effect.Two kinds of delivery methods could both reduce the MDA content of liver,and had almost the same effect; but the subcutaneous injection group had better effect on increasing the liver's SOD activity,and the intraperitoneal injection had better effect on increasing liver's GSH-PX activity.Intraperitoneal injection had better effect on reducing kidney' s MDA content and increased SOD activity.Two kinds of delivery methods had the same effect on reducing the heart's MDA content.Conclusion The two delivery methods can both make the MDA levels of KK mice in serum,heart,liver and kidney fall to as normal as that of control group,but the two delivery methods have different ways of improving the antioxidant capacity in different organs.Intraperitoneal injection can reduce MDA content in serum and kidney better.

Objective To analyze the efficacy and prognosis of different antiviral agents on compensated hepatitis B cirrhosis.Methods Eight hundred and sixty-five cases of Hepatitis B patients with compensated cirrhosis were randomly divided into five groups:A group(n =143,subcutaneous injection interferon 3 million U every other day for 48 weeks),B group(n =171,orally treatment with lamivudine 100 mg/d for 48weeks),C group(n =137,orally treatment with adefovir 10 mg/d for 48 weeks),D group(n =83,oral treatment with entecavir O.5 mg/d,for 48 weeks) and E group(n =331,treated with general hepatoprotective drugs).Clinical symptoms and signs,changes in liver function were observed and prothrombin time activity degrees (PTA),quantitative HBV-DNA,HBeAg seroconversion and HBeAg/HBeAb conversion situation were detected.Results There were significant differences on HBeAg seroconversion between A group and other four groups after treated for48 weeks(31.5％ vs 13.5％,22.6％,18.1％,5.7％,x2 =58.56,P ＜0.01) and at the end of follow up (33.1％ vs 14.2％,23.3 ％,23.6％,6.4％,x2 =52.87,P ＜ 0.01).Patients' condition in A,B,C,D groups progressed slowly,and their incidence rates of decompensate cirrhosis were significantly lower than that in group E(x2 =122.41,P ＜ 0.01).The incidence rate of liver cancer in group A was significantly lower than that in B,C,D,E groups (x2 =19.61,P ＜ 0.01).Conclusion Antiviral therapy of interferon and nucleoside drugs can slow the progression of compensated Hepatitis B cirrhosis and reduce the incidence rates of decompensate cirrhosis.And interferon can significantly reduce the incidence rate of liver cancer.

Objective To explore the relationship between infant feeding practices and infants growth,especially the weight gain for length in the first 6 months of life. Methods Two-hundred healthy full-term singlet normal birth weight 5 - 6 months old infants and their main care givers were recruited in Kongjiang community health service center in Shanghai. The questionnaires included infants feeding pattern, feeding environment and care givers feeding behaviors, and were completed on-site by investigators. The birth weight was obtained. The weight and length of infants at 6 months were measured. Results There were 70/200 (35.0%) infants overweight (BMI for age Z score>+1) at 6 months. There were more overweight boys than girls (40.0% vs. 30.9%, x2 = 1.798, P = 0.180). Compared with normal weight infants, the overweight infants had same birth weight (3.30 ± 0.35 kg vs. 3.35 ± 0.32 kg, t =1.010, P = 0.314) and same length at 6 months (67.64 ± 2.10 cm vs. 67.91 ± 1.97 cm, t=- 0.896, P = 0.371). However, the overweight infants gained much more weight for length in the first six months of life. At 6 months, the weight and BMI of overweight infants was significantly higher than that of normal weight infants (9.16 ± 0.67 vs. 7.94 ±0.64, t = 12.324, P < 0.01;19.86 ± 1.24 vs. 17.41 ± 0.80, t = 14.953, P < 0.01). The rates of exclusive breastfeeding for at least four months, continued breastfeeding at six months, complementary food consistency, and complementary feeding frequency, were not significantly differenct between overweight and normal weight infants (x2 =0.723 - 2.701, P > 0.05). The grandparents played an important role in infants feeding in Shanghai. There were 39.0% infants fed only by grandparents, and 23.0% infants fed jointly by grandparents and parents (x2 = 0.175, P > 0.05).The care givers' educational level and knowledge of feeding skill were similar in overweight and normal weight infants (x2 = 0.446, t = 0.949, P > 0.05). However, the overweight infants were fed more quickly than normal weight infants (Z = 2.753, P < 0.01), and there was less language communication between care givers and overweight infants during feeding (Z = 2.932, P < 0.01). In overweight infants, the overfeeding behaviors of care givers were positively correlated with BAZ (r = 0.281, P < 0.05). Conclusions Overweight in early life is associated with some particular infants feeding behaviors of care givers in Shanghai. The long term effect of more rapid weight gain for length in the first 6 months of life on the risk of childhood obesity warranted to be further followed and researched.

Objective To observe the efficacy and side effects of combined therapy with victoria A acid,arsenic trioxide and chemotherapeutics for newly diagnosed acute promyelocytic leukemia (APL). Methods 40 cases of patients were treated with combined therapy of ATRA, As2O3 and chemotherapy. The efficacy and side effects were analysed. Results 92.5 % (37/40) achieved complete remission(CR).
