Objective To review the occurrence and relevant factors of adverse drug reactions (ADR) of Xueshuantong Injection. Methods Articles and documents in CNKI, VIP, and CBM were searched in June 2014 according to incorporation and exclusion standard. The dose, indication, medicating path and method, solvent, as well as the duration of treatment course and adverse reaction of Xueshuantong Injection were analyzed. The national information system for monitoring ADR was searched to collect adverse reaction cases of Xueshuantong Injection (2004.9-2014.9) reported in Lanzhou region. Cases were analyzed and under analogy with literature results. Results Totally 66 articles involving 4686 patients were included (except for patients of control group). Adverse reactions occurred in 767 patients, including skin damage (402 cases), systemic damage (221 cases), gastrointestinal system damage (75 cases). All of these were relieved after treatment. There were 11 adverse reaction cases of Xueshuantong Injection from Lanzhou region reported in the national information system for monitoring ADR. Conclusion There is a high incidence of adverse reactions in the clinical application of Xueshuantong Injection and ratio of serious adverse events report.

BACKGROUND: Conventional hemodialysis mainly for cleaning uremic micro molecule substance, such as urea nitrogen or creatinine; however, few hemodialyses can clean uremic middle molecule substances (MMS). With prolonged dialysis duration, MMS accumulates in vivo and induces a series of complications. OBJECTIVE: To compare the efficiency of adsorptive dialysis (hemoperfusion unites hemodialysis) and conventional hemodialysis in cleaning uremic MMS. METHODS: Totally 60 maintenance hemodialysis patients were averagely divided into the adsorptive dialysis group and conventional hemodialysis group. First of all, hemoperfusion apparatus and dialyser were connected in series to take the adsorptive dialysis in the adsorptive dialysis group (hemoperfusion apparatus were equipped before dialyser). 120 minutes later, the hemoperfusion apparatus was toke off and continues to hemodialysis for 120 minutes. Duration of conventional hemodialysis was 240 minutes. Changes in clinical symptoms and levels of liver function, kidney function, serum electrolytes, hemocytes and uremic MMS were observed prior to and after treatment. RESULTS AND CONCLUSION: Adsorptive dialysis could remove the MMS notably. Compared with the conventional hemodialysis group, a single 120 minutes treatment could decrease MMS significantly (P < 0.05). The platelet levels were obviously decreased in the adsorptive dialysis group after treatment (P < 0.05), which were significantly different from the conventional hemodialysis group (P < 0.05). There was no significant difference in liver function, kidney function or serum electrolytes concentration. But related symptoms, such as the skin itch, sleep disorders and myalgia, were relieved more or less.

Objective To establish a method for determination of cipro-floxacin concentration in human serum by high performance liquid chro-matography-fluorescence detector method ( HPLC-FLD).Methods Ciprofloxacin and the internal standard ( IS) gatifloxacin were extracted from human serum after protein precipitation by 5%perchloric acid , then detected with fluorescence detector after excitation at 278 nm after sepa-ration by an Eclipse XDB -C18 (150 mm ×4.6 mm,5 μm).The mobile phase consisted of acetonitrile -phosphate ( pH 3 ) =15∶85 , with a flow rate of 1.0 mL· min-1 using gradient elution .Results Linear calibra-tion curves were obtained in the range of 0.05 -50.00 μg · mL-1 ( r>0.999 5 ).Intra-day RSD were in the ranges of 0.98%-2.63%and inter-day RSD were in the ranges of 1.87%-3.16%.Conclusion The method provides a sensitive , accurate , precise and reliable analy-tical procedure for clinical monitoring of ciprofloxacin in serum.

Objective To assess the optimal voriconazole dosing regimens for obese patients.Methods PubMed, EmBase, the Cochrane Library, Clinicaltriasl.gov and three Chinese databases ( CNKI, CBM, and Wan-Fang ) were searched through March 2015.Clinical trials or observational studies comparing the clinical and pharmacokinetic outcomes of different dosing regimens in obese patients or healthy subjects were included.Results Three cohort studies involving 237 subjects were included in the review.There were no statistical difference among actual body weight ( ABW) , ideal body weight ( IBW) , adjusted body weight ( AdjBW) and normal body weight ( NBW) groups on rates of hepatotoxicity and neuro-toxicity.No studies reported clinical response of treatment.Attainment of target concentration in AdjBW group was significantly higher than ABW and NBW group , respectively.Random plasma concentration in ABW group was significantly higher than NBW group when using intravenous administration (Median 6.4 vs 2.8μg· mL-1 ).Trough concentration in ABW group was significantly higher than NBW ( MD=2.70μg· mL-1 ) , IBW ( MD=2.25μg· mL-1 ) and AdjBW ( MD =2.90 μg · mL-1 ) groups , respectively.Conclusion Voriconazole AdjBW and IBW dosing regimens are recommended for obese patients.Drug monitoring may be necessary for obese patients to ensure the safety of voriconazole.

Objective:To identify the risk factors for failure in closed reduction of flexed supracondylar humerus fractures of Wilkins type Ⅲ in children.Methods:The data of 171 children were retrospectively analyzed who had been treated for flexed supracondylar humerus fractures of Wilkins type Ⅲ from January 2013 to December 2021 at Department of Orthopaedics, Children's Hospital of Jiangxi Province and Children's Hospital of Fudan University Anhui Hospital. They were divided into a reduction failure group (35 cases) and a reduction success group (136 cases). Factors such as fracture height, age, body mass index, ulnar-radial offset direction, obvious axial rotation of the distal fracture fragment, combined ulnar nerve injury, and time from injury to operation were listed as risk factors. The independent risk factors for failure in closed reduction of flexed supracondylar humerus fractures were identified by univariate analysis of variance and multi-variate logistic regression analysis.Results:The average age of 171 children was (7.8±2.6) years. There were 151 cases of radial deviation and 20 cases of ulnar deviation, 120 high type fractures and 51 low type fractures, and 20 cases of combined ulnar nerve injury and 115 cases of obvious rotation of the distal fracture fragment. The one-way ANOVA showed statistically significant differences between the reduction failure group and the reduction success group in terms of age, obvious rotation of the distal fracture fragment, and ulnar nerve injury ( P<0.05), but no significant differences in fracture height, body mass index, ulnar-radial offset direction, or time from injury to operation ( P>0.05). Multivariate logistic regression analysis showed that obvious rotation of the distal fracture fragment ( OR=3.287, 95% CI: 1.136 to 9.513, P=0.028) and combined ulnar nerve injury ( OR=6.439, 95% CI: 2.262 to 18.327, P=0.001) were risk factors for failure in closed reduction. Conclusion:As obvious rotation of the distal fracture fragment and combined ulnar nerve injury may be independent risk factors for failure in closed reduction of flexed supracondylar humerus fractures of Wilkins type Ⅲ in children, they should arouse more attention in the treatment of such fractures.

OBJECTIVETo investigate the relationship between plasma levels of fibrinogen, the-beta455 G/A fibrinogen gene polymorphism and the severity of periodontal inflammation and to explore the possible role of fibrinogen in the association of periodontitis with coronary heart disease (CHD).

METHODSA total of 121 patients with moderate to severe periodontitis and periodontally healthy and gingivitis controls were enrolled in the study. Peripheral blood samples were collected and the plasma fibrinogen levels were determined by the clotting method of Clauss. Polymerase chain reaction and restriction fragment length polymorphism analysis with Hae III were used to examine the -beta455 G/A fibrinogen gene polymorphism.

RESULTSFibrinogen levels were significantly higher in moderately or severely chronic periodontitis patients [(3.45 +/- 0.68) g/L] than periodontally healthy and gingivitis controls [(2.47 +/- 0.42) g/L, P < 0.001]. The carrier status of the A allele at position -455 in the beta fibrinogen gene was associated with elevated fibrinogen levels and the frequency of the-A455 allele in the beta fibrinogen gene in the patient group was significantly higher than in the control group (P = 0.032). Carriers of the -A455 allele were about 3-fold more likely to have moderate or severe periodontitis as compare to individuals without the -A455 allele( OR = 3. =135, P= 0.008).

CONCLUSIONSFg-beta455 G/A polymorphism may contribute to the elevated plasma fibrinogen levels and put individuals at higher risk of having severe periodontitis. As the independent risk factor of CHD, fibrinogen levels and Fg-beta455 G/A polymorphism may play a role in the pathogenesis of periodontitis.

In order to study phylogeography, population dynamics and molecular evolution of rabies viruses (RABVs) isolates from China, especially spatio-temporal dynamics, the timescale of RABVs evolution and its pattern of migration, we performed an extensive comparative analysis of RABV N gene sequence data, representing 167 isolates sampled from 20 provinces in a 78-year period (from 1931 through 2009). The available Chinese isolates could be divided into two distinct clades:Phylogroup clades I comprised Chinese group 1-4; Phylogroup clades II contained Chinese group 5-8. We found no evidence for positive selection (dN/dS>1) acting at any codon and found strong selective constraints for N gene. Bayesian Markov Chain Monte Carlo (MCMC) analysis suggested that the Chinese rabies viruses originated within the last 2000 years and the mean rates of nucleotide substitution for the N gene were approximately 4 x 10(-4) substitutions per site per year. The analyses of the spatial and spatio-temporal evolution indicated that RABV isolates from China migrated among different Provinces.

OBJECTIVETo synthesize Gal-BSA-SPIO as the magnetic resonance imaging (MRI) contrast agent targeting asialoglycoprotein (ASG) receptors in the liver and observe its role in MRI detection of hepatocellular carcinomas (HCCs).

METHODSGal-BSA was synthesized by means of reductive amination and mixed with SPIO in ice bath to prepare Gal-BSA-SPIO complex. Twenty rabbits bearing VX2 liver tumor underwent MRI enhanced by SPIO (n=10) and Gal-BSA-SPIO (n=10), and the T2 values of the liver and tumor before and after the contrast imaging were measured. Fresh human normal hepatic tissues (n=3), cirrhotic tissues (n=4) and HCC tissues (n=6) were obtained and incubated with Gal-BSA-SPIO followed by Perl's Prussian blue staining to observe the distribution of ASG receptors.

RESULTSThe size of the Gal-BSA-SPIO particles was 34.4 nm. The 20 rabbits bearing VX2 tumor, with tumor size ranging from 3 mm to 12 mm, showed isointense signal in the liver and hypointense signal in the tumor on T1WI, and isointense signal in the liver and slightly hyperintense signal in the tumor on GRE T2*WI. The signal intensity of the liver decreased slightly or moderately after administration of SPIO in the rabbits, and administration Gal-BSA-SPIO resulted in obvious reduction in the signal intensity of the liver. The signal intensities of the tumors did not exhibit obvious changes after the administration of SPIO or Gal-BSA-SPIO. Histological examination revealed numerous blue iron deposits in the Kupffer cells in SPIO group and in the hepatocytes in Gal-BSA-SPIO group, but not in the tumors in either of the groups. The human liver specimens incubated with Gal-BSA-SPIO contained numerous blue iron deposits in the hepatocyte cytoplasm and cell membrane in normal liver tissue, but the deposits were reduced in the cirrhotic tissue and almost absent in the HCC tissue.

CONCLUSIONGal-BSA-SPIO can specifically bind to ASG receptors on hepatocyte membrane to improve the tumor-liver contrast-to-noise ratio.

OBJECTIVETo investigate the correlation between moderately and severely chronic periodontitis and coronary heart disease, as well as the role of fibrinogen in the mechanisms responsible for the correlation between periodontitis and coronary heart disease.

METHODS95 subjects who were systemic health or patients of coronary heart disease with or without periodontitis were enrolled. All the subjects were placed into 4 groups based on their periodontal status and cardiovascular health. The 4 groups were healthy control group (HC), moderately and severely chronic periodontitis group (MSP), coronary heart disease group(CHD), and MSP coexisted with CHD group (MSP+CHD). Clinical periodontal index were examined, at the same time, plasma fibrinogen levels and serological changes used in diagnosing of cardiovascular disease routinely were determined. ANOVA and ANCOVA were used in the statistical analysis.

RESULTSFibrinogen levels of HC, MSP, CHD, and MSP+CHD group were (2.36+/-0.37), (3.63+/-0.73), (4.08+/-0.84), and (4.14+/-0.96) g/L, respectively. Fibrinogen levels of MSP and MSP+CHD group were significantly higher than that of healthy controls (P<0.01). The patients with moderately to severely chronic periodontitis were more likely to have coronary heart disease as compared to periodontally healthy controls (OR=2.527, P=0.047) after adjusted for blood pressure and body mass index.

CONCLUSIONModerately and severely chronic periodontitis maybe a risk factor of coronary heart disease and fibrinogen could be one of the biological basis which links periodontitis with coronary heart disease.

Objective To investigate the effect of one of the acute-phase proteins,fibrinogen,on the release of IL-1β and-8 by human peripheral polymorphonuclear leukocytes (PMN)and the possible role of fibrinogen during the destruction of periodontium. Methods Peripheral PMN were isolated by discontinuous density gradient centrifuging technique. The freshly isolated PMN were suspended in Hank's balaneed saline solution(1×109/L)supplemented with 0.5% BSA and 0.1% glucose.The levels of I-1β and-8 in the supernatants produced by cultured cells upon the addition of human fibrinogen at different concentrations were measured by ELISA technique. Results Incubated with human fibrinogen at 2 g/L or 10 g/L for different time periods,human peripheral PMN released significantly greater amount of IL-1β [(10.41±0.37)-(35.86±0.30)ng/L or(22.81 ± 0.45)-(57.77±2.08)ng/L]and IL-8[(93.90 ±13.95)-(2045.66±53.03)ng/L or(115.02±10.61)-(3858.69 ± 25.65)ng/L]than PMN without the stimulation offibrinogen(IL-1β,P＜0.001,and IL-8,P≤0.016).The higher concentration of fibrinogen or the longer treatment time,the higher levels of IL-1β and -8 were released by PMN(P＜0.001).Conclusions Fibrinogen induced the secretion of pro-inflammatory cytokines IL-1β and-8 by PMN and may be involved in magnification of the inflammatory response of periodontium and bone resorption.
