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.

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 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 compare the quality differences in benzalkonium chloride samples from domestic and abroad to provide references for the quality standard revision for benzalkonium chloride in Chinese pharmacopoeia. Methods: The ratio of alkyl compo-nents was determined according to the method described in USP 38, and the total content of benzalkonium chloride was determined ac-cording to the method recorded in Chinese Pharmacopoeia (2015 edition) and USP 38, respectively. Results:According to the results of composition ratio of alkyl, the fraction defective of domestic samples and imported samples was 100% and 50%, respectively. The content difference between the values calculated by the methods in the two pharmacopoeias showed that the total content of domestic samples changed from 3. 86% to 4. 15%, and that of imported samples changed from 1. 15% to 3. 90%. Conclusion:There are sig-nificant differences in the quality of benzalkonium chloride between domestic samples and imported samples. It is recommended that the ratio of alkyl components should be supplemented in our pharmacopoeia referring to the method in USP 38 and the total content calcula-tion formula for benzalkonium chloride should be revised to improve the quality standard for benzalkonium chloride.

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.

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.
