Loop-mediated isothermal amplification (LAMP) is a novel in vitro nucleic acid amplification method conducted under isothermal conditions with the advantages of high specificity, sensitivity, rapidity and easy detection. Since it was established in 2000, it has been widely applied in various fields of analytical science including the diagnosis of a variety of pathogens, identification of embryo sex, detection of genetically modified organisms and cancer gene identification. Additionally, significant progress has been made in the optimization of the LAMP method, such as accelerated reactions, simplified sample processing, the realization of multiplex amplification, and the enhanced specificity of reaction and detection methods. LAMP technology also shows much potential to be adopted as part of point-of-care testing platforms by the micromation, automation and integration with other technologies such as Lab-on-a-Chip and digital nucleic acid amplification. This review summarizes the latest advances in the LAMP technique and its applications in developing point-of-care testing platforms.

Objective To investigate the value of lumbar puncture in the diagnosis of subarachnoid hemor-rhage of aneurysms .Methods The clinical data of 13 patients diagnosed negative by computer tomography(CT) scanning and then as subarachnoid hemorrhage (SAH) followed by lumbar puncture and as aneurysms by catheter digital subtraction angiography(DSA) were retrospectively analyzed.Results The positive rate was 100% by lum-bar puncture.Conclusion Lumbar puncture is of great significance in the diagnosis of subarachnoid hemorrhage of aneurysms, which should be applied reasonably.

A sophisticated effort is made to uplift the clinical nursing quality in hospitals, which aims at improving hospital nursing quality by means of enhancing the management functionality of the nursing department, enhancing nursing systems, implementing clinical paths, and quality service campaigns. These efforts are designed to effectively improve hospital nursing quality.

From the view of medical professionals, this paper explored the standards of residents′ competency cultivation in Zhuhai using Delphi method. The research outcome that consisted of 53 factors and 6 dimensions was obtained after two rounds of expert consultation. There are 6 first-level indexes including professionnalism and body-mind quality, clinical practice skill, the competency of lifelong learning and self-improvement, humanistic medicine practice skill, medical knowledge, and the competency of promoting the medical system to develop. As well, there are 18 second-level indexes and 29 third-level indexes. The standards stated that the clinical prac-tice skill would not be the main part of residents′competency cultivation. Qualified residents should reach the na-tional standard of the clinical practice skill but also the other five indexes.

Objective To analyze the change of the proportions of the hospitalization causes in patients with chronic heart failure(CHF) in a single-central hospital in late 20 years.Methods 1 259 hospitalized cases diagnosed primarily as chronic heart failure were selected from the First Central Hospital of Tianjin during 1983-2002,and divided into two groups with a decade interval.A comparative analysis was performed to explore the proportions of the primary,concomitant and multiple causes of hospitalization for CHF patients between two groups.Results(1) The most common primary causes in general cases was coronary artery disease(CAD,56.6%),rheumatic heart disease(RHD,20.9%) and pulmonary heart disease(PHD,9.2%).During the latter decade,the proportions of CAD and dilated cardiomyopathy(DCM) increased,while RHD,PHD,congenital heart disease(CHD) decreased.(2) The causes of concomitant disease for CHF was essential hypertension(EHT,44.0%),diabetes mellitus(DM,16.4%),chronic obstructive pulmonary disease(COPD,14.3%),cerebral-vascular disease(CVD,11.4%) and anemia(5.2%).All proportions of these concomitant diseases except COPD increased during the latter decade(P

To compare the efficacy and side effects of bupivaeaine(Bup)at two concentrations and fentanyl for caudal analgesia in children. Method:One hundred-fifty children undergoing hernia repair procedures under caudal anesthesia, were randomly assigned to five groups. Group A: 1% lidocaine (Lid), group B: 10% Lid+0.1% Bup, group C: 1% Lid+0.25% Baeup, group D: 1%Lid+0.15%Bup with 2?g?kg~(-1) fentanyl, group E: 1%Lid+0. 25%Bup with 2?g?kg~(-1) fentanyl for caudal analgesia, The degree of pain(LPS), nausea and vomiting (NV) were as sessed at 4, 8, 12 and 24 h after operation. Result: The numbers of LPS

Objective To investigate the effects of medullary reaming on respiratory and circulatory system in dog model during total hip replacement. Methods Twelve mongrels were randomly divided into two groups. In control group, femoral necks were cut while femoral canals were not disturbed. In experimental group, femoral canals were reamed with femoral rasps as done in total hip replacement. The changes of hemodynamics and pulmonary function were monitored during perioperative period. The postmortem pulmonary tissues were studied by pathological examination. Results No fat embolus was found in any lung sections of control group. Meanwhile, pulmonary fat emboli were found in all of experimental group. After fat embolism happened, cardiopulmonary effects included increased pulmonary artery pressure, pulmonary shunt and pulmonary vascular resistance accompanying a decrease in partial pressure of oxygen and cardiac output. There is statistically significant difference in response between the two groups. Conclusion The present study showed that embolic events and intraoperative pulmonary impairment are common during reaming of femoral medullary canal in total hip replacements. Further research can be made with this model in order to reduce the risk of fat embolism syndrome.

Objective To describe the effect of cannualted rasps in reduc in g the fat embolic risks during preparation for femoral canal in experimental tot al hip arthroplasty. Methods Twelve mongrels were used to perform resection of b ilateral femoral heads, and randomly assigned to one of two groups with six each . In experiment group, impacting cannulated rasp was used in preparing femoral c anal; while, in control group, impacting traditional rasp was used. Both the ras ps were of same shape; however, there was a 4 mm diameter canal inside the cannu lated rasp connecting its two ends. A bone hole was made through the lateral fem oral cortex to the femoral canal at a point 12 cm distal to the greater trochant er in order to measure the intramedullary pressure of femoral canal when the fem oral canal was prepared with either rasp. The pathology of the postmortem pulmon ary tissue was analyzed. Using quantitative morphometry, the size of fat embolus in the lung tissues and the volume proportion of lung tissues occluded by fat w ere measured respectively. The statistical differences between the two groups we re analyzed using t test. Results In control group, the intramedullary pressure during preparation of femoral canal with traditional rasp increased with a peak of (34.5?10.2)kPa, pulmonary fat emboli were found in all mongrels, the volum e proportion of postmortem lung tissue occluded by fat was 0.64%, and pulmonary arterial pressure increased to (2.2?0.4)kPa[the normal value was (0.8?0.3 )kPa]; while in the experiment group, the intramedullary pressure peak increas ed to (22.4?7.7)kPa, significantly lower than that of the control group; the volume proportion of lung tissue occluded by fat was 0.21% which was also signif icantly lower than that of the control group, and pulmonary arterial pressure wa s (1.7?0.4)kPa. The differences between the two groups were significant in al l measured values. Conclusion The present study suggests that conventional prepa ration of canal can cause an increase of intramedullary pressure, which may lead to pulmonary fat embolism and cardiopulmonary impairment. However, the cannulat ed rasp can decrease the volume proportion of lung tissue occluded by fat and al leviate the influence of preparation of canal on cardiopulmonary function.
