ObjectiveTo assess the efficacy and safety of Xuebijing injection for the treatment of severe acute pancreatitis (SAP).Methods An extensive search of related literatures from the Cochrane Library, EMBASE, China Biology Medicine (CBM), CNKI, VIP and Wanfang data up to March 2014 was performed. Randomized controlled trials (RCTs) regarding Xuebijing injection for the treatment of SAP were collected regardless of languages. Jadad scale was taken for quality evaluation of the included studies by two researchers. The patients in control group were given conventional treatment, and those of the Xuebijing group were given Xuebijing injection on the top of conventional treatment. The Cochrane Collaboration RevMan 5.2 software was used for data analysis regarding the effect of Xuebijing injection on the mortality, incidence of complication, effective rate, the length of stay in hospital, and the safety of the drug in patients with SAP.Results A total of 15 published reports meeting the inclusion criteria were enrolled. The methodological quality of the trials was low. Meta analysis showed that the mortality in Xuebijing group was significantly lower [odds ratio (OR) = 0.37, 95% confidence interval (95%CI) =0.17 - 0.77,P = 0.008], and the incidence of complication was also significantly decreased (OR = 0.26, 95%CI =0.14 - 0.45,P< 0.000 01) as compared with those of control group. The effective rate in Xuebijing group was significantly higher than that of the control group [relative risk (RR) = 0.85, 95%CI = 0.80-0.91,P< 0.000 01]. The length of stay in hospital in Xuebijing group was significantly shorter than that of the control group [mean difference (MD) = -5.28, 95%CI = -6.69 to -3.86,P< 0.000 01]. Adverse reactions of Xuebijing injection were reported in 2 studies. The adverse reaction in one study was headache and nausea, which were relieved by adjusting the speed of intravenous infusion, and mild rash was reported in another case, and it disappeared after the withdrawal of Xuebijing. Conclusions The currently available evidence shows that Xuebijing injection may have some therapeutic effect on SAP. Because of the low methodological quality of the included trials, multi-center and high-quality RCTs with large sample sizes are needed to provide stronger evidence.

OBJECTIVETo assess the diagnostic value of magnetic resonance imaging (MRI) in the follow-up of patients with hepatocellular carcinomas treated with radiofrequency ablation (RFA) and to compare it with that of computed tomography (CT).

METHODSFrom December 2009 to September 2011, 40 patients (47 hepatocellular carcinomas) were treated with RFA after transcatheter arterial chemoembolization and underwent MRI and CT for follow-up. RFA margins were assessed on a five-point scale with receiver operating characteristic curve analysis. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were evaluated.

RESULTSThe interobserver agreement rate for MRI was significantly higher (Kappa=0.935) than for CT (Kappa=0.714; P < 0.05). The scores of 1 and 5 points for MRI, which confirms the presence or absence of residual tumor, accounted for 89.4% (84/94), while for CT accounting for only 31.9% (30/94). The area under the receiver operating characteristic curve of MRI was significantly higher than that of CT (P < 0.05), as were the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of detection rate (mean, 100%, 96.4%, 76.9%, 100%, and 96.8% for MRI, respectively, vs. 30.0%, 57.1%, 10.3%, 87.7%, and 63.8% for CT).

CONCLUSIONMRI is superior to CT in assessing the RFA margins in terms of the diagnostic accuracy and detection rate .

Sanqi in Chinese herbal medicine is the root and rhi-zoma of Panax notoginseng (Burk.)F.H.Chen. As the effects of strengthening with tonics, promoting blood circulation to re-move blood stasis,relieving swelling and pain and hemostasia,it is widely used as a tonic medicine in the traditional Chinese medicine. The main active constituents of Sanqi are panax noto-ginseng saponins,including ginsenoside Rg1,Rb1 and notogin-senoside R1. Notoginsenoside R1 is one of the unique monomer compositions of panax notoginseng,which is often used as an in-gredient indicator in new drug research and development.In cur-rent years, the scientists have been conducted tremendous fun-damental studies to research the pharmacological activities of no-toginsenoside R1, to reveal its protective effects on the cardio-vascular system,central nervous system as well as to many other aspects. It is hoped that the relevant study about the pharmaco-logical action of notoginsenoside R1 would help its further clini-cal application. This paper mainly reviews the research on the pharmacological mechanism of notoginsenoside R1 in recent years.

OBJECTIVETo study the expression level and significance of glucose transporter 1 (Glut-1) in normal breast tissue, adenosis, adenoma and breast carcinoma.

METHODSA total of 147 cases of female breast tissue samples, including 92 cases of invasive ductal carcinoma, 26 cases of breast fibroadenoma, 24 cases of breast adenosis and 5 cases of normal breast tissues, were collected for quantitative detection of the expression of Glut-1 protein by immunohistochemistry (EnVision method) and Western blot, and its mRNA by reverse transcriptase-polymerase chain reaction (RT-PCR).

RESULTSIn normal breast tissue and benign lesions of the breast, Glut-1 was undetectable or only weakly detectable in cytoplasm of ductal and acinar epithelia. In contrast, the intensity of Glut-1 staining was significantly higher in invasive ductal carcinomas (P = 0.0002) with protein expression predominantly in cellular membrane and lesser in cytoplasm. Western blot and RT-PCR analyses showed that the expression of Glut-1 protein and mRNA were significantly increased in invasive ductal carcinoma than fibroadenoma (P =0.001 for protein; P <0.05 for mRNA) and adenosis (P =0.001 for protein; P < 0.05 for mRNA). There was a significant difference among groups (P = 0.0002 for protein; P = 0.0001 for mRNA).

CONCLUSIONSGlucose transport activity, as indicated by Glut-1 protein and its mRNA expression, significantly increases in breast carcinoma than non-cancerous lesions. The over-expression of Glut-1 in breast carcinoma is tightly coupled with tumor cell proliferation, invasion and metastasis, implying that Glut-1 may serve as a new marker in the early diagnosis and prognostication of breast malignancy as well as a new therapeutic target.

OBJECTIVETo study the correlation of vascular endothelial growth factor-C (VEGF- C) expression and lymphatic microvessel density (LMVD) with clinicopathological features and prognosis in colon cancer.

METHODSThe expression of VEGF-C and VEGFR-3 was detected by immunohistochemical staining with monoclonal antibodies against VEGF-C and VEGFR-3 in 44 cases with primary colon cancer. LMVD was calculated.

RESULTSVEGF-C positive rate was 43.2% (19/44). VEGF-C expression was associated with tumor (P=0.003), lymph node metastasis (P=0.002), Dukes stage (P=0.001). The mean LMVD was 10.14+/- 4.19. LMVD was associated with lymph node metastasis (P=0.002), Dukes stage (P=0.001). LMVD in VEGF-C(+) group was (11.34+/- 4.83) higher than (9.24+/- 3.48) in VEGF-C(-) group, but there was no statistically significance between the two groups (P=0.105). The survival rate of the patients with positive VEGF-C was lower than that with negative VEGF-C (P=0.0225). The median survival time of the patients with LMVD(+) group was shorter than that with LMVD(-) (P=0.0036). Distant metastasis (P=0.0004), lymphatic metastasis (P=0.021) and LMVD (P=0.0469) were independent prognostic factors.

CONCLUSIONSVEGF-C and LMVD appear to be new prognostic factors for colon cancer. Furthermore, LMVD may be a new independent prognostic factor.

Neospora caninum is the etiologic agent of bovine neosporosis, which affects the reproductive performance of cattle worldwide. The transmembrane protein, NcSRS2, and dense-granule protein, NcGRA7, were identified as protective antigens based on their ability to induce significant protective immune responses in murine neosporosis models. In the current study, NcSRS2 and NcGRA7 genes were spliced by overlap-extension PCR in a recombinant adenovirus termed Ad5-NcSRS2-NcGRA 7, expressing the NcSRS2-NcGRA7 gene, and the efficacy was evaluated in mice. The results showed that the titer of the recombinant adenovirus was 10(9)TCID50/ml. Three weeks post-boost immunization (w.p.b.i.), the IgG antibody titer in sera was as high as 1:4,096. IFN-gamma and IL-4 levels were significantly different from the control group (P<0.01). This research established a solid foundation for the development of a recombinant adenovirus vaccine against bovine N. caninum.

Although indigenous malaria has been eliminated in Wuhan since 2013,imported malaria remains a potential threat as an infectious source of local malaria transmission.The epidemiological and clinical characteristics of imported malaria are particularly important in areas where local malaria has been eliminated.This study was aimed at analyzing the epidemiological and clinical characteristics of imported malaria in Wuhan from 2012 to 2019,to provide a basis for further improving the preven-tion and control of imported malaria.Patients in Wuhan diagnosed with imported malaria from January 1,2012,to December 31,2019,were included in this study.A case-control study was con-ducted to analyze the features of patients with severe malaria.Uni-variate and multivariate logistic regression was used to identify risk factors for prolonged hospital length of stay(LOS).Among 229 imported malaria cases,212(92.6％)were in Chinese citizens,and most cases were in men(96.5％).The gender ratio is 28:1,and the age of cases is mainly concertrated between 18 and 50 years old(89.1％).More than 80％of patients were mi-grant workers,and most cases were infections from African countries(92.6％).Plasmodium falciparum(80.8％)was the dominant species.Fifty-three severe malaria cases were identified during the study period.Compared with uncomplicated cases,severe cases tended to occur in patients with no history of malaria(P=0.008),patients infected with Plasmodium falciparum(P=0.009),and patients who were initially misdiagnosed(P＜0.001).The median LOS was 6 days,and the species of infec-tion(Plasmodium falciparum),the use of antimalarial drugs(group B),antipyretic time(longer than 3 days),and the turn-around time of blood smear microscopy(longer than 3 days)were significantly associated with longer LOS(all P＜0.05).Al-though malaria has been eradicated in Wuhan for many years,imported cases continue to pose a threat.Efforts should be made to strengthen malaria knowledge education for outbound personnel.Additionally,medical institutions must enhance diagnosis and treatment capabilities for malaria,and adhere to standardized treatment processes,and the development of drug resistance and occurrence of severe malaria must be prevented.
