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 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.

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.

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.

AIM:To study the effects of astragali radix extract(ARE)on renal resistance to atrial natriuretic peptide(ANP)in rats with experimental nephrotic syndrome.METHODS:Male Sprague-Dawley rats were randomly divided into normal control,adriamycin nephropathy(ADR),ADR treated with ARE(2.5 g? kg-1? d-1)and ADR treated with benazepril(10 mg? kg-1? d-1).After 6 weeks,rats received intravenous infusion of 2% body weight isotonic saline.Urinary cGMP excretion(UcGMPV),plasma ANP level,renal PDE5 activity and protein expression were also detected.RESULTS:ARE increased UNaV while ACEI was not natriuretic.Nephrotic rats had a blunted natriuretic response and reduced rate of UcGMPV after volume expansion despite higher plasma ANP concentration.ARE increased UcGMPV and restored partly natriuretic response to volume expansion.The activity and protein abundance of renal PDE5 were high in nephrotic rats.ARE significantly reduced the PDE5 activity and protein expression.CONCLUSION:ARE may ameliorate the renal resistance to ANP in rats with adriamycin nephropathy by inhibiting the PDE5.

4-fold elevation in renal cortex in plasma aldosterone as compared to those of the SHAM rats. The above pathologies were markedly improved in bi-ectomised rats with significantly lower aldosterone level. Being constantly infused exogenous aldosterone, bi-ectomized rats manifested greater proteinuria, hypertension, glomerulosclerosis and increased level of TGF-?1 compared to bi-ectomised rats. Indeed, these features were similar in exogenous aldosterone rats and 5/6 nephrectomized rats. Furthermore, the expression of mineralocorticoid receptor (MR) mRNA was remarkablely enhanced in SNX group and was decreased in ADX group. However, the mRNA expression of 11 ?-hydroxysteroid dehydrogenase II (11?-HSD2) in each group was opposite to that of MRmRNA. Ccr and kidney/body weight showed no differences among four experimental groups. Conclusion Aldosterone contributes to the progression of ablative nephropathy in the rat through mechanisms other than systolic blood pressure.

ObjectiveTo evaluate the reliability and clinical value for detecting paraquat (PQ)concentration in serum by spectrometry. MethodsThe determinations of wave length for detecting serum PQ concentration by ordinary spectrometry and second-derivative spectrometry were carried out. When the second-derivative spectrometry was used for detecting PQ in serum, the linear range and precision for PQ concentration were well defined. The results of serum PQ concentration determined by second-derivative spectrometry and by HPLC (high performance liquid chromatography) were compared in 8 patient with PQ poisoning. A total of 21 patients with acute poisoning after PQ ingestion over 4 hours admitted from October 2008 through September 2010 were retrospectively studied. Patients were divided into two groups as per the serum concentrations more than 1.8 μg/mL or less than that by second-derivative spectrometry on the day of admission. The severity of clinical manifestations between two groups was analyzed with t-test or Fisher's exact probabilities analysis. Results ( 1 ) The absorption peak of 257 nm could not be found by using ordinary spectrometry to detect the PQ concentration in serum. (2) The calibration curve in the 0. 4 ～ 8.0μg/mL range for detecting PQ concentration by second-derivative spectrometry observed the Beer's law (r =0. 996) . The average retrieval rate of PQ was within the range of 95.0％～ 99. 5％ with relative standard deviation (RSD) within 1.35％～ 5.41％ ( n = 6), and the lowest detection limit was 0. 05μg/mL. (3) The results of PQ concentrations from 8 patients with PQ poisoning detected by second-derivative spectrometry were consistent with those of the quantitative determinations by HPLC ( r = 0. 995,P＜0. 01 ) . (4) The survival rate of patients with serum PQ concentration more than 1.8 μg/mL was 22. 2％ ,and the incidences of acidosis, oligouria and pneumomediastium in these patients were 55.6％,55. 6％ and 77.8％, respectively. These clinical manifestations were significantly different from those in patients with serum PQ concentration less than 1.8 μg/mL ( P ＜ 0. 05 ) . Conclusions ( 1 ) It was inappropriate to take 257 nm as the determination wave length for detecting serum PQ concentration by ordinary spectrometry. (2) The method of second-derivative spectrometry was reliable for detecting serum PQ concentration. (3) Serum PQ concentration detected by second derivative spectrometry could be used to predict the severity of clinical manifestations of patients with PQ poisoning and was an important predictive factor for poor prognosis if the serum PQ concentration more than 1.8 μg/mL after PQ ingestion over 4 hours.
