Sepsis can cause life-threatening organ dysfunction and is one of the leading causes of death in critically ill patients. Early diagnosis and correct treatment of sepsis are the key to reducing the fatality, however, there is no golden standard for diagnosis at present. The ideal sepsis biomarker can be used for early diagnosis and predicting poor prognosis with good sensitivity and specificity. There are many candidate biomarkers for sepsis. This article reviews the latest developments on acute phase proteins, soluble receptors, non-coding RNAs and other candidate biomarkers of sepsis that attracted more recent attention.

Chronic hepatitis B (CHB) is often treated with drugs such as interferons and nucleoside (acid)/nucleotide (acid) analogs. While these drugs are effective in controlling the viral loads, they are not able to eliminate hepatitis B virus (HBV) from the body completely. Besides, side effects and drug resistance may by caused by the long-term use of these drugs. Several monoclonal antibodies (McAbs) against HBV, mostly against hepatitis B surface antigen (HBsAg), have been demonstrated with viral neutralization capability and with effective inhibition of HBV replication in relevant animal models. The use of a McAb individually or in combination with another therapy has the potentials to achieve functional cure of CHB. In this review, we summarized the encouraging results from the research and development of anti-HBV McAbs in clinical or pre-clinical development stage, aiming to provide new idea for the treatment of CHB.

Objective: To evaluate the therapeutic effect and security of Buyang Huanwu decoction in treatment of the ischemic stroke recovery. Methods: We retrieved the relevant articles of random and semi- random control trials in treating ischemic stroke recovery using Buyang Huanwu decoction, published in China National Knowledge Infrastructure (CNKI), the Wanfang Data, the Weipu Information Resources System, the Chinese Biomedical Literature Database (CBM), Cochrane Library, PUBMED and MEDLINE from the date of establishment until to March 2018. The quality of studies was evaluated according to the Cochrane Reviewers?? handbook 5.1, and the study was carried out using Cochrane system assessment methods. Statistical analysis was performed with Rev Man 5.3. Results: Altogether 39 studies and 3539 cases of ischemic stroke recovery were enrolled. In terms of clinical efficacy, the difference between Buyang Huanwu Decoction and Western Medicine conventional therapy in the treatment of ischemic stroke was significantly different from that of conventional western medicine therapy [RR =1.26, 95％CI (1.20, 1.31), Z =10.05, P ＜ 0.00001], and the difference between Buyang Huanwu Decoction and other Chinese patent medicines was statistically significant [RR =1.12, 95％CI(1.06, 1.19), Z =3.82, P =0.0001]; neurological deficit NIHSS score [MD =-2.55, 95％CI (-3.10, -2.01), Z =9.20, P ＜ 0.00001]; clinical neurological deficit score (CSS) [MD =-3.85, 95％CI (-5.21, -2.50), Z =5.56, P ＜ 0.00001]; limb motor function score (FMA) [MD =6.10, 95％CI (1.19, 11.01), Z =2.43, P =0.01]; Barthel Index of Daily Living Activity Scale [MD =9.09, 95％CI (6.95, 11.23), Z =8.33, P ＜ 0.00001]; In terms of improving blood rheology index, serum peroxide lipid (LPO), serum superoxide dismutase (SOD) and other biochemical indicators, due to the small number of studies, it may have a certain effect. Most studies did not report adverse reactions. Conclusion: Based on the existing clinical evidence, combination of Buyang Huanwu decoction and western medicine has higher clinical efficacy than western medicine alone for the ischemic stroke recovery. Due to the limited methodological quality of the included studies, more high- quality RCTs with large scale are needed to increase the strength of the above evidence.

[Abstract ] Objective Globular C1q receptor (gC1qR), a highly acidic receptor protein, is expressed in almost all mamma-lian cells in addition to exoerythrocytic, which can mediate a variety of biological responses.The study aimed to explore gC1qR expres-sion in cervical cancer and itd effects on the biological behaviors of human cervical cancer cells. Methods Retrospective analysis was made on 100 cervical tissue samples of patients in Nanjing Maternal and Child Health Hospital from August 2014 to April 2015, in-cluding 50 cervicitis tissues and 50 cervical cancer tissues.Immunohistochemical SP method was applied in the research of cervical cancer cell line C33a to detect the expression and the location of gC1qR in cervical tissues.Real-time PCR and Western blot analysis were respectively applied to detect the levels of gC1qR mRNA and gC1qR protein expression.Besides, the abilities of C33a cells mi-gration, invasion and apoptosis were respectively assessed by in vitro cell wound healing experiment, transwell assay and flow cytome-try. Results The expression of gC1qR gene was dramatically decreased in the group of cervical cancer tissues when compared with chronic cervictis group (2.18 ±0.37 vs 7.23 ±0.69, 0.27 ±0.09 vs 0.74 ±0.02, P<0.001).gC1qR overexpression could result in sig-nificant up-regulation of cervical celluer apoptosis([22.89 ±1.46]%vs [12.98 ±0.57]%) and down-regulation in migration ([42.60 ± 3.29]%vs [141.83 ±4.71]%) and invasion([26.20 ±2.89]%vs [67.13 ±0.95]%).Typical apoptosis was also observed in cervi-
cal cells by transmission electron microscope. Conclusion gC1qR expression might play an important role in inhibiting the invasion and migration of cervical cancer cells and inducing the apoptosis of cervical carcinoma cells, which provides new clues and potential targets for the treatment of cervical cancer in further research.

Human enterovirus 71 (EV71) is the main causative pathogen of hand, foot, and mouth disease (HFMD) in children. The epidemic of HFMD has been a public health problem in Asia-Pacific region for decades, and no vaccine and effective antiviral medicine are available. Curcumin has been used as a traditional medicine for centuries to treat a diversity of disorders including viral infections. In this study, we demonstrated that curcumin showed potent antiviral effect again EV71. In Vero cells infected with EV71, the addition of curcumin significantly suppressed the synthesis of viral RNA, the expression of viral protein, and the overall production of viral progeny. Similar with the previous reports, curcumin reduced the production of ROS induced by viral infection. However, the antioxidant property of curcumin did not contribute to its antiviral activity, since N-acetyl-l-cysteine, the potent antioxidant failed to suppress viral replication. This study also showed that extracellular signal-regulated kinase (ERK) was activated by either viral infection or curcumin treatment, but the activated ERK did not interfere with the antiviral effect of curcumin, indicating ERK is not involved in the antiviral mechanism of curcumin. Unlike the previous reports that curcumin inhibited protein degradation through ubiquitin-proteasome system (UPS), we found that curcumin had no impact on UPS in control cells. However, curcumin did reduce the activity of proteasomes which was increased by viral infection. In addition, the accumulation of the short-lived proteins, p53 and p21, was increased by the treatment of curcumin in EV71-infected cells. We further probed the antiviral mechanism of curcumin by examining the expression of GBF1 and PI4KB, both of which are required for the formation of viral replication complex. We found that curcumin significantly reduced the level of both proteins. Moreover, the decreased expression of either GBF1 or PI4KB by the application of siRNAs was sufficient to suppress viral replication. We also demonstrated that curcumin showed anti-apoptotic activity at the early stage of viral infection. The results of this study provide solid evidence that curcumin has potent anti-EV71 activity. Whether or not the down-regulated GBF1 and PI4KB by curcumin contribute to its antiviral effect needs further studies.

OBJECTIVETo learn more about the clinical and laboratory features of patients with paroxysmal nocturnal hemoglobinuria (PNH) diagnosed in the past ten years.

METHODSClinical and laboratory data for 78 cases of PNH diagnosed from January 1990 to November 1999 in our hospital were analyzed retrospectively.

RESULTSIn comparison with PNH cases reported in the 1980s, the newly diagnosed PNH cases showed the following features: (1) older age of disease onset (from 27 to 34 years); more female cases (from 18.5% to 38.5%); more cases without hemoglobinuria (from 24.2% to 38.5%). (2) No positive family hereditary history. (3) Bone marrow dysplasia, abnormal karyotype and negative sister chromatid differentiation were found in 19.2%, 12.2% and 8.9% of the PNH patients, respectively. 12.3% of the patients had bone marrow hypoplasia, and most of them had no hemoglobinuria. Ham's tests were negative in about 34.2% of the cases. CD55 and CD59 on peripheral blood cells were deficient in 100.0% of the cases, suggesting that CD55 and CD59 tests can improve the diagnosis of PNH. (4) Adrenocortical hormone was effective in 83.8% of the patients, 54.2% of whom relapsed within one year. Eight refractory and relapsed patients were treated with low dose chemotherapy (MP therapy: Melphalan 2 - 6 mg x d(-1); Prednisone 0.5 mg x kg(-1) x d(-1)). Five (62.5%) of them showed positive responses. Bone marrow failure and other side effects were not serious in this group of patients.

CONCLUSIONSPNH, an acquired blood disease seen more often among adult males, can be diagnosed more sensitively by hemocyte member CD55 and CD59 tests and treated more effectively with adrenocortical hormone or low dose chemotherapy.

OBJECTIVETo study the in vitro effects of low-molecular weight heparin (LMWH) and dexamethasone on the hemolysis of red blood cells from paroxysmal nocturnal hemoglobinuria (PNH) patients.

METHODSBy Ham's test and micro-complement lysis sensitive test (mCLST), the changes of hemolysis of red blood cells from 6 PNH patients were tested by adding different doses of LMWH and dexamethasone into the test mixture. The effects of LMWH and dexamethasone on the coagulation of the tested blood samples were also studied by activated partial thromboplastin time (APTT).

RESULTS(1) Either LMWH or dexamethasone could dose-dependently inhibit the hemolysis of PNH red blood cells, and the effects were synergistic when added together. The same dose of LMWH induced a less than 100% prolongation of APTT. (2) Dexamethasone could inhibit the hemolysis in Ham's test and had different effects on the hemolysis by different adding methods in mCLST. LMWH could inhibit the hemolysis in both Ham's test and mCLST.

CONCLUSIONBoth LMWH and dexamethasone could inhibit the hemolysis of PNH red cells and showed a synergistic effect. The mechanisms of the inhibition of hemolysis were different. Furthermore, a tolerable dose of LMWH induced only a limited prolongation of APTT, which might be useful for controlling acute hemolysis and reducing the dose of dexamethasone.

OBJECTIVETo understand the clinical feature and natural course of polycythemia vera (PV).

METHODSThe clinical symptoms, signs, laboratory examination and prognosis of 185 patients with PV were analysed.

RESULTSThere are 122 males and 63 females. The mean age was (52.7 +/- 14.1) years. The mean hemoglobin level was (208.3 +/- 21.2) g/L. Pancytosis was displayed in 74 (40%) cases, excess of red blood cells in 33 (17.8%), excess of red blood cells and granulocytes in 67 (36.2%) and excess of red blood cell and platelets in 11 (5.9%). Splenomegaly was found in 123 (66.5%) patients and hepatomegaly in 30 (16.2%). Quantitative assess of serum Epo was done in 25 patients. The level was low in 16 (64.2%) and normal in 9 (36.0%). Hematopoietic progenitor culture yields was elevated in 11 patients, endogenous erythroid colonies (EEC) formation was found in 10 cases (90.9%). Eighty two patients (44.3%) had 101 attacks of vascular thrombotic incidents, 7 patients developed myelofibrosis (MF). Secondary cancer occurred in 1 patient. Two patients died of thrombosis.

CONCLUSIONPV is an elderly adult myeloproliferative disease with a high frequency of thrombosis. EEC can be found out in PV patients. The serum Epo level is not increased in PV patients. The main sequelae of PV is MF.
