This study was aimed to investigate the expressions of vascular endothelial growth factor (VEGF) and cyclooxygenase-2 (COX-2) in patients with multiple myeloma (MM) and its clinical significance. Expression of VEGF was detected by enzyme linked immunosorbent assay (ELISA) and the level of COX-2 was detected by Western blot. The results showed that the serum VEGF level of multiple myeloma patients (365.34 +/- 65.63 pg/ml) was higher than that in the normal persons (122.52 +/- 39.29 pg/ml) (p < 0.05); the serum VEGF level of patients at advanced stage (395.07 +/- 54.90) pg/ml was higher than those at stable stage (300.33 +/- 44.22) pg/ml (p < 0.05). The serum Cox-2 positive rate in the patients (31%) was higher than that in normal persons (0%) (p < 0.01); the serum Cox-2 positive rate in the patients at advanced stage (50%) was higher than those at stable stage (21%) (p < 0.01). It is concluded that VEGF and COX-2 may play an important role in the pathogenesis and development of multiple myeloma, they can be used to evaluate the status of patients with MM.

OBJECTIVETo assess the performance of a minimally invasive thoracic drainage tube (14 F) made of polyurethane (PU) in a rabbit model of hemothorax in comparison with the conventional 28 F chest tube (CCT).

METHODSThirty New Zealand rabbits were divided into experimental chest tube (ECT) group (n=9), CCT group (n=6), and blood provider group (n=15). Blood samples (20 mL) collected from the blood providing rabbits were injected into the chest cavity of the rabbits in the other two groups, and the time taken for closed drainage of the thoracic cavity was recorded. The rabbits in ECT and CCT groups were subjected to blood injections (20 mL for each injection) into the chest cavity every 20 min for 5 times, and the volumes of blood drained by ECT and CCT were measured. Two hours later, the rabbits were sacrificed and the residual blood and blood clots in the chest cavities were observed.

RESULTSCompared with CCT, the use of ECT significantly shortened the operation time (P<0.05) and produced more effective blood drainage at 20 min and 40 min after the placement of the drainage tube (P<0.05). No significant difference was found in the total blood volume drained between ECT and CCT groups, but the volume of residual blood in the thoracic cavity was significantly smaller in ECT group than in CCT group. No post-operative complications were found in the rabbits in ECT group while all the rabbits in CCT group had abutment pressure to the lung.

CONCLUSIONCompared to CCT, ECT is less invasive and allows more effective thoracic drainage with more convenient operation and reduced postoperative complications, suggesting its potential for use in closed thoracic drainage in single-port video-assisted thoracoscopic surgery (VATS) or in pediatric patients.

Objective To compare the clinical features of severe hand foot and mouth disease between enterovirus(EV)71 and other EV to find specific diagnosis index of EV71 severe hand foot and mouth disease.Methods Case definition were adopted from national guideline of hand foot and mouth disease diagnose(Version 2010).Clinical data of severe hand foot and mouth disease came from case history and contents of questionnaire would include the ones between the time of onset and diagnoses being made.EV and EV71,Cox A16 nucleic acid tested were by RT-PCR in stopl samples.Clinical features of severe hand foot and mouth disease between EV71 and other EV were compare.Results There appeared statistical differences between neurologic symptoms such as tremor,myoclonic jerk,listlessness,convulsion and white blood cell counts in CSF(P<0.05).Results from the step Fisher discriminant analysis showed only tremor and white blood cell had an increase in CSF,with statistically significant differences.The discriminant equation of EV71 was Y=3.059X1+3.83X5-2.742 and the equation of other EV was Y=1.634X1+1.623X5-1.693.The specificity of EV71 was 91% and the specificity of other EV Was 40%.Conclusion The increase of clinical features of tremor and white blood cell in CSF could be used as diagnosis index of severe EV71.

The aim of this study was to investigate the gene expression of programmed cell death 5 (pdcd5) in plasma and bone marrow cells from patients with multiple myeloma (MM). Enzyme liked immunosorbent assay (ELISA) and real-time quantitative reverse transcription polymerase chain reaction (RQ-RT-PCR) were used to examine pdcd5 gene expression in plasma and marrow cells in 45 MM patients and 20 normal controls. The results showed that serum levels of PDCD5 protein in 45 MM patients were lower significantly compared with the normal controls and 20 responsive patients after chemotherapy, their plasma levels were (16.91 +/- 0.28) ng/ml, (19.11 +/- 0.29) ng/ml and (17.94 +/- 0.154) ng/ml respectively (p < 0.05). The pdcd5 gene expression levels detected by RQ-RT-PCR in 45 MM patients were lower significantly compared with the normal controls, their pdcd5 gene expression levels were 0.64 +/- 0.47 and 1.28 +/- 1.21 respectively (p < 0.05). It is concluded that the PDCD5 protein expression levels are low in patients with MM. These findings suggest that abnormal expression of pdcd5 may be involved in the pathogenesis of MM.

This study was aimed to detect the expression level of cmtm 5 (CKLF-like MARVEL transmembrane domain containing member 5) gene in the bone marrow cells from patients with multiple myeloma (MM), and to investigate the correlation between the expression level of cmtm5 and various clinical characteristics. Real-time quantitative reverse transcription polymerase chain reaction (RQ-RT-PCR) was used to measure the expression levels of cmtm5 gene in the bone marrow cells collected from MM patients, and the MM cell lines, namely, RPMI8226 and CZ1 cells. The normal donor marrow specimens were used as the reference. The ratio of cmtm5 copy number to abl (Abelson murine leukemia viral oncogene homolog) gene copy number was used for indicating the expression level. The results showed that the expression level of cmtm5 gene was significantly down-regulated in bone marrow cells of 51 untreated or relapsed/refractory MM patient as compared to those of normal donor marrow cells (0.047+/-0.062 for the untreated or relapsed/refractory MM patients versus 0.255+/-0.333 for the normal, p<0.01). According to the International Staging System (ISS), the cmtm5 expression level in marrow cells of patients in ISS III stage was significantly lower than that in patients in ISS I stage (0.034+/-0.034 for the ISS III stage versus 0.103+/-0.109 for ISSI stage, p<0.01). Similarly, lower expression levels of cmtm5 gene were also found in two human MM cell lines (0.014+/-0.009 for RPMI8226 cells and 0.004+/-0.006 for CZ1 cells). After the MM patients were effectively treated, their expression levels of cmtm5 gene significantly increased (0.020+/-0.005 for the untreated patients versus 0.227+/-0.038 for the effectively treated patients, p<0.01). A significant negative correlation was observed between the expression level of cmtm5 gene and the number of bone marrow plasma cells (r=-0.307, p<0.05). However, the correlation was not found between the expression level of cmtm5 gene and the clinical characteristics, such as gender, age, hemoglobin level, or M-protein level, etc. It is concluded that the expression level of cmtm5 gene is abnormally lower in the bone marrow cells from the MM patients, and are associated with ISS stages. Furthermore, the expression level of cmtm5 gene is negatively correlated with the number of bone marrow abnormal plasma cells in MM patients, which suggests that the abnormally lower expression of cmtm5 may be involved in the pathogenesis of the MM patients.

OBJECTIVE: To observe the effect of acupuncture combined with rehabilitation training on cognitive function and amino acid metabolism in children with cerebral palsy. METHODS: Twenty children with cerebral palsy (cerebral palsy group) were randomly divided into an acupuncture and rehabilitation group (11 cases) and a rehabilitation group (9 cases), and 10 healthy children were included as the normal group. The rehabilitation group was treated with rehabilitation training, 30 min each time; on the basis of rehabilitation training, the acupuncture and rehabilitation group was treated with acupuncture at Sishenzhen, Zhisanzhen, Naosanzhen, Niesanzhen, Dazhui (GV 14), Shenzhu (GV 12), Mingmen (GV 4), etc. The Sishenzhen (left and right points) and the ipsilateral Niesanzhen were respectively connected with a group of electrodes, intermittent wave, frequency of 2 Hz for 30 min. Both groups were treated once every other day, three times a week, totaling for 3 months. The Gesell developmental diagnostic scale (GESELL) was used to evaluate the developmental quotient (DQ) scores before and after treatment, and the blood samples of children with cerebral palsy before and after treatment and normal children were collected for amino acid metabolomics. RESULTS: Compared before treatment, the DQ scores of adaptation, fine motor and social in the acupuncture and rehabilitation group was increased after treatment ( CONCLUSION Acupuncture combined with rehabilitation training could improve cognitive function in children with cerebral palsy, and the effect may be related to the down-regulation of L-histidine and L-citrulline metabolism.
