Retained products of conception (POC) complicates nearly 1% of all pregnancies, occurring with greater frequency after termination of pregnancy than after vaginal or caesarean delivery. The presenting symptoms of retained products of conception are similar to those of gestational trophoblastic disease and hence accurate differentiation is difficult based on clinical history and physical examination alone. The distinction between these two entities is extremely important as the treatment differs dramatically. These patients often need to be further evaluated with either ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) of the pelvis. Hence, radiologists play a vital role in clinching the diagnosis although at times it may be challenging to differentiate between these two entities. Herein, we discuss a case of degenerated retained products of conception which was initially misdiagnosed as invasive trophoblastic disease in a 41-year-old woman whom last known pregnancy was 10 years ago.

OBJECTIVE:To observe clinical efficacy and safety of Shuxuening injection in the adjunctive treatment of traumat-ic subarachnoid hemorrhage. METHODS:96 patients with traumatic subarachnoid hemorrhage were randomly divided into control group and observation group with 48 patients in each group. Control group was given Tranexamic acid injection,Nimodipine injec-tion and Citicoline injection,daily lumbar punctrive and determined intracranial pressure and drained cerebrospinal fluid via lumbar puncture;observation group was additionally given Shuxuening injection 20 ml added into 5% Glucose injection 250 ml,ivgtt,qd. Both group were treated for consecutive 2 weeks. Clinical efficacy of 2 groups were observed,and GCS and MCA were also ob-served before and after treatment;ADR of 2 groups were recorded. RESULTS:Excellent rate of observation group(60.42%)was significantly higher than that of control group(31.25%),with statistical significance(P<0.05). Before treatment,3 and 5 days af-ter treatment,there was no statistical significance in GCS and MCA between 2 groups(P>0.05);7 and 14 days after treatment, GCS of 2 groups increased significantly while MCA decreased significantly,and the observation group was better than the control group,with statistical significance (P<0.05). The incidence of cerebral vasospasm,cerebral infarction and cerebral hemorrhage were 8.33%,4.17%and 4.17%in observation group,and those of control group were 16.67%,12.50%and 16.67%;the observa-tion group was significantly lower than the control group,with statistical significance(P<0.05). CONCLUSIONS:Shuxuening in-jection shows significant therapeutic efficacy in the adjunctive treatment of traumatic subarachnoid hemorrhage,with low incidence of ADR.

Objective To analyse the prognostic value of serumal copeptin in patients with acute exacerbation of COPD compli-cated withrespiratory failure.Methods The serumal copeptin were detected in 60 hospitalized AECOPD patients before and after the treatment and in 30 healthy controls.Results Comparing with control groups,the serumal levels was significantly elevated in the patient with AECOPD before thetreatment and declinied two months later(P <0.05).The level of serum copeptin wereincreasing with the increase in the severity of the disease in acertain extent;The serumalcopeptin were positively correlated with lung function and CAT (r=0.058 and 0.821,P =0.00)and were negativelycorrelated with 6MWD(r=-0.652,P =0.00).Conclusion Serum copeptin could as-sess the incidence of acute exacerbations ofchronic obstructive pulmonary disease and its therapeutic effect;Serum copeptin can reflect the se-verity of AECOPD patients in a certain extent,and has certain clinical value to evaluate the quality of life in patients.

Objective To assess the effect of rhein on diabetic nephropathy in rats with type 2 diabetes mellitus. Methods Diabetes was induced by high-lipids and high-sucrose diets (20% sucrose, 10% lard, 2.5% cholesterol, 1% cholic acid and 66.5 % regular chow, w/w) for 1 month and then intraperitoneal injection with 25 mg/kg streptozoticin(STZ) in female inbred Wistar rats. Rhein was continuously given 100 mg?kg-1?day-1 for 6 months 1 week after STZ injection in rhein-prevented group, and 1 month after STZ injection in rhein-treated group. Blood and urinary biochemistry and renal morphology were evaluated at divers times. Results Rhein ameliorated hypertriglyceridemia and hypercholesterolemia, but had few effect on the level of plasma glucose in both rhein-prevented group and rhein-treated group. Excretion of urinary protein reduced markedly and stable-state plasma glucose (SSPG) level decreased in both groups as compared with diabetic group. Examination of kidney sections from both rhein-prevented group and rhein-treated group showed that the structural lesions of glomeruli including mesangial expansion, diffuse glomerulosclersis and thickening of glomerular basement membrane, as well as artery injury such as arteriolar hyalinosis, atherosclerosis were markedly improved as compared with diabetic group. Morphometry of glomeruli from both rhein-prevented group and rhein-treated group showed that glomerular grow and mesangial hypertrophy occurred in diabetic group were ameliorated. The accumulation of fibronectin examined by immunostaining in glomeruli was reduced in both groups. Conclusion Therapeutic intervention with rhein can halt the progression of diabetic nephropathy and prevent the development of glomerulosclerosis and vascular injuries in this animal model of type 2 diabetes mellitus.

Huaier (Trametes robiniophila) has been widely used as an adjuvant drug for cancer treatment in China. The anti-cancer effect of Huaier extract has been confirmed in liver cancer, lung cancer, breast cancer, ovarian cancer, gastric cancer, and so on. The main mechanisms by which Huaier exerts an anti-neoplastic effect include inhibition of the growth and proliferation of cancer cells, induction of apoptosis of cancer cells, suppression of angiogenesis, inhibition of the invasion and migration of cancer cells, regulation of oncogenes and tumor suppressor genes expression, improving immunity, and reversal of drug resistance in cancer cells. In order to provide references for further study and clinical application on anti-tumor effect of Huaier, the latest research progress on anti-tumor effect of Huaier in recent years is summarized in this paper.

Objective To study the long-term neurodevelopment in term neonates with hyperbilirubinemia and explore the predictive value of cerebrospinal fluid neuron specific enolase (CSF-NSE) on long-term neurodevelopment outcome.Methods A mental and psychomotor scale for 0-4 years old was performed to evaluate the intelligence development of 39 neonates with hyperbilirubinemia and 39 randomly selected healthy controls when they were at 3 to 24 months old. The former were tested for the level of CSF-NSE in jaundice climax.Results There was significant difference between 2 groups in total development quotient (DQ) tested at 3 month and 24 month old (P=0, 0.047). It was shown that the DQ scores for fine activity and social behavior were significantly lower in the study group than those in the control group (Pa=0). Furthermore, within the hyperbilirubinemia group, CSF-NSE was significantly associated with DQ of 3 month and 24 month old, while there was not association with TSB. The correlation coefficients were -0.46(P=0.04) and -0.32(P=0.047),respectively.Conclusions Hyperbilirubinemia may influence long-term neurodevelopment of term infants and CSF-NSE can predict this outcome.

Objective:To observe the influence of isehemia-reperfusion(I/R)on hepatoma growth and on the expression of genes associated with tumor metastasis and recurrence(VEGF and MMP-9)in the adjacent tissues of cancer in nude mice. Methods:BALB/c nude mouse model bearing Hep3B-tumor in the liver was established and the model mice were evenly randomly into 5 groups:sham group and ischemia/reperfusion 1 h,6 h,5 d,and 7 d groups(n=8).I/R models were established by blocking porta hepatic;the sham group underwent the same treatment as the I/R model group except for blocking of porta hepatic.ALT and AST were detected in I/R 1 h and 6 h groups.Real-time-PCR was employed to detect the change of VEGF and MMP-9 in the adjacent tissues of cancer and the results were compared with that of the control group(n=6). Histopathological changes of liver were studied by H-E staining and necrotic areas were calculated in I/R 5 d and 7 d groups (n=6).The remnant tumor bearing mice were sacrificed 2 weeks after I/R to measure the volume and mass of the tumors. Results:Two weeks later,the tumor volume and mass in I/R group were increased compared with those in the sham group ([209.6?25.74]mm~3 vs[330.6?32.01]mm~3,[0.214?0.036]g vs[0.374?0.045]g,P

Objective To establish the national standard materials for haemiglobincyanide (HiCN) for the traceability assays of hemoglobin. Methods HiCN national standard materials were established according to the document of International Committee for Standardization in Haematology (ICSH). The standard materials were certificated according to ISO Guide 35, including homogeneity and stability. Then they were characterized by the calibrated spectrophotometer which can be traceable to National Institute of Standards and Technology (NIST). The international reference materials of HiCN were compared with the result of the WHO reference laboratory to confirm the reliability. Results The uncertainty of the HiCN standard materials was 0.000 4 g/L and the variation coefficient (CV) was 0.09%. The uncertainty of long-term stability was 0.000 6 g/L; the certificated value of the standard materials was 0.615 9 g/L with uncertainty of 0.000 4 g/L. The combined uncertainty was 0.000 9 g/L and the expanded uncertainty was 0.001 8 g/L when the cover factor was 2. The relative error was 0.08% between the result of the standard materials and the international certificated value. Conclusion The homogeneity and stability of the standard material is acceptable and the method of characterization is accurate and reliable.
