1.Functional hemodynamic monitoring should be emphasized in intensive care for burn and trauma patients.
Chinese Journal of Burns 2014;30(4):291-294
Hemodynamic monitoring is a very important measure for critically ill patients with burn and trauma, and it should be carried out throughout the course of treatment. Functional hemodynamic monitoring consists of the assessment of the dynamic interactions of hemodynamic variables in response to a defined volume change. Accordingly, response of fluid volume can be assessed in a quantitative fashion by measuring variation of both arterial pulse pressure and left ventricular stroke volunime during positive pressure breathing, or the change in cardiac output response to passive leg raising maneuver. Functional hemodynamic monitoring, contrary to that of static condition in order to realize dynamic and individual monitoring, is related to response to treatment, and it is a useful complement to static (routine) hemodynamic monitoring. At present, in the care of sepsis, shock, and mechanical ventilation, etc. related to burn injury and trauma, functional hemodynamic monitoring is more and more accepted and applied by medical personnel of ICU in burn and trauma departments. Therefore, further study on functional hemodynamic monitoring should be emphasized and practised.

Up to date, eight types of human herpes viruses have been identified, all of which are ubiquitous, and usually establish latent infection in the host after primary infection. Since most of the herpes viruses are maintained in an asymptomatic form, they are often neglected. However, under some circumstances, these herpes viruses can cause fatal or severe diseases. Furthermore, the association of herpes viruses with hematopoietic malignancies is attracting researchers' attention. With the extensive development of hematopoietic stem cell and organ transplantation, reports regarding transplantation failure and complication caused by infection of human herpes virus has been increasing. Cytokine storm was firstly suggested as the mechanism of graft-versus-host diseases. In recent years, which has also been applied in the pathogenesis research of inflammation, and is supposed to play an important role in severe virus infection. In this paper, through discussing the possible role of latent infection of human herpes virus in the failure or complication of bone marrow or hematopoietic stem cell transplantation, and in refractory leukemia, the function and significance of latent infection of human herpes virus and the cytokine storm it caused were investigated.

Fibrolase is a non-hemorrhagic zinc metalloproteinase isolated from southern copperhead snake venom (Agkistrodon contortrix contortrix) and is capable of degrading fibrin clots resulting from purified fibrinogen or from blood plasma. Alfimeprase, a truncated form of fibrolase, as a clinical agent was successfully completed PhaseII clinical trials.The cDNA of alfimeprase was amplified by recursive PCR, digested with BamHI and HindII, and cloned into pET43.1a, pMALp2X and pMALc2X vectors to generate fusions with NusA, MBP and sMBP(with signal peptide), respectively. Nus/alfimeprase was expressed in soluble form by co-expressing with chaperone FkpA and inducing with1mmol/L IPTG. The fusion protein accounted for about 25 % of total protein following cell lysis. Alfimeprase was successfully purifiesd by Ni-NTA affinity chromatography and cleaved by enterokinase. The results demonstrate the fibrinolytic activity of recombinant alfimeprase using fibrin plate assays and fibrinogen hydrolysis.

Sulfate-reducing bacteria (SRB) are widespread in the environment. SRB are obligate anaerobes and capable of dissimilatory reduction of sulfate. SRB have application prospects in the control of environmental pollution due to that many pollutants can be removed by SRB. The biological characteristics and metabolic mechanisms of SRB are introduced, and the application of SRB in the treatment of environmental pollution is described in this paper. The research progress of Cr(Ⅵ ) reduction and Cr(Ⅵ ) removal from wastewater by SRB is reviewed, and future direction of research on the control of Cr(Ⅵ ) pollution by SRB is also analysed.

Objective To study whether carbon dioxide used to establish pneumoperitoneum has an influence on port-site and intraperitoneal implantation and metastasis of tumor cells. Methods R 15 hepatic cancer cells were injected into 30 Wistar rats’ peritoneal cavities 1 hour before operation, then the 30 Wistar rats were randomly divided into 3 groups: gasless group, helium group and carbon dioxide group. The suspension was exposed to the gas environment for 2 hours, all animals were killed after 28 days and the port-site and intraperitoneal implantation and metastasis of tumor cells were examined.Results On port-site, intestinal serous coat, mesentery, greater omentum and diaphragm, the weights of tumor cells, in carbon dioxide group were (326.7?230.3) mg, (626.2?215.9) mg, (476.2?204.8) mg,(2 536.5?906.7) mg and (384.5?149.9) mg respectively; in helium group were (235.6?107.3) mg, (414.2?148.4) mg, (261.8?92.6) mg, (1 633.4?247.3) mg and(220.0?57.9) mg; in gasless group were (145.0?42.4) mg, (221.5?108.2) mg, (212.5?109.6) mg, (797.5?335.9) mg and 113.0 mg.The weights of carbon dioxide group showed a significant increase, compared with helium group and gasless group (P 0.05). Conclusion The insufflation of carbon dioxide promotes intraperitoneal tumor implantation and growth compared with helium and gaslessness in a rat model.

OBJECTIVETo study clinical value of shear wave elastography (SWE) in the evaluation of neck-shoulder myofascial pain syndrome.
METHODSFrom December 2013 to July 2014,30 patients diagnosed as neck-shoulder myofascial pain syndrome were in the treatment group,including 17 males and 13 females, with an average age of (44 ± 3) years old. Thirty healthy people were in the control group, including 22 males and 8 females, with a mean age of (37 ± 5) years old. The patients in the treatment group were treated with manipulation, once every other day, total 7 times. The SWE was used to detect tension part of trapezius muscle of patients in the treatment group before and after treatment, as well as to detect muscle belly at the descending part of trapezius muscle in the control group. The tissue elasticity and Yang's modulus value were recorded and compared.
RESULTSThe tissue elasticity chart of patients in the treatment group before treatment was mainly greenish blue with the score of 3.70 ± 1.53, and the Yang's modulus was (43.4 ± 15.6) kPa. The tissue elasticity figure after treatment was mainly blue with the score of 2.40 ± 0.87, and the Yang's modulus was (29.0 ± 5.9) kPa. Whereas in the control group, the tissue elasticity figure was mainly blue with the score of 1.60 ± 0.72, and the Yang's modulus was (24.0 ± 7.6) kPa. These were statistical differences between the two groups (P = 0.000).
CONCLUSIONSWE can be used as an evaluation method of manipulation treatment for neck-shoulder myofascial pain syndrome, which is an objective and sensitive detection method.
