Objective To investigate the clinical significance of serum sialic acid (SA) in the diagnosis and treatment of IgA type multiple myeloma (MM). Methods The level of serum SA in 50 healthy subjects and 70 patients with MM were determined. Results In MM group, there were 25 cases of IgA type, 51 cases of other than IgA type (40 cases of IgG type, 7 cases of light chain type MM, 4 cases of non-secreting type MM). In healthy subjects, patients with IgA, IgG, light chain, non-secreting types and other than IgA type, the serum SA levels were (570.33 ± 67.72) mg/ L, (1289.24 ± 325.42) mg/ L, (585.88 ± 159.12) mg/L, (600.77 ± 126.90) mg/L, (590.50 ± 100.86) mg/L, and (588.39 ± 150.90) mg/L. The serum SA level of IgA type patients was higher than those of healthy subjects and other types (all P<0.01), and there was no significant difference among the other groups (all P> 0.05). The serum SA level of IgA type patients had positive correlations with serum IgA, globulin, bone marrow smear myeloma cell population and ESR (r values were 0.699, 0.753, 0.504, and 0.732, all P< 0.05); the serum SA level of IgA type patients had negative correlations with serum albumin, IgG, hemoglobin and platelet (r values were -0.712, -0.505, -0.629, and -0.596, all P< 0.05). The serum SA level of IgA type patients had no correlation with leukocyte, serum creatinine, serum IgM, lactic dehydrogenase, serum calcium, C-reactive protein and β2-microglobulin (all P>0.05). The level of serum SA in IgA type patients decreased with the improvement of the condition, and increased with the severity of the disease. Conclusions In MM patients, serum SA level in IgA type is high. The serum SA is an index for reflecting the tumor load capacity, and can evaluate the therapeutic efficiency of IgA type MM patients.

OBJECTIVETo explore the working mechanism and age-related change of the conflict processing system of the frontal cortex.
METHODSFifteen normal elderly people and 15 youth were performed a modified Eriksen flanker paradigm, while event-related potential (ERPs), which include 32 systerm electroencephalography, reaction time and correct rate were recorded.
RESULTSThe elderly group showed a distinct effect of reaction time and effect of conflict in the respond level compared with the youth group. The elderly group had a longer time window of N380 and same amplitude as the youth group. Low resolution brain electromagnetic tomography (LORETA) showed the bilateral temporal lobe and the dorsolateral prefrontal cortex (especially right) were activated in the youth group, while the left temporal lobe, the left dorsolateral prefrontal cortex and left medial frontal gyrus were activated in the elderly group.
CONCLUSIONWhen conflict stimuli existed in the response level, old people showed frontal interference control hypofunction. N380 reflected the activation of the left dorsolateral prefrontal cortex and the left temporal lobe during response selection and executive control processing in older people.

10. Efficacy and toxicity analysis of domestic and imported precision radiotherapy equipment in the treatment of lymphoma
Academic Journal of Second Military Medical University 2020;41(5):527-534
Objective To clarify the advantages and disadvantages of domestic precision radiotherapy equipment by comparing the clinical efficacies of domestic and imported precision radiotherapy equipments in the treatment of lymphoma. Methods We investigated the treatments of lymphoma in hospitals of different levels using domestic and imported medical linear accelerators and divided them into domestic and imported groups. The data of patients in the two groups were retrospectively analyzed, and the radiotherapy equipment brand, short-term efficacy, acute toxicity, dosimetric parameters of organs at risk and the costs of radiation therapy were compared between the two groups. Results A total of 101 cases receiving radiation therapy for lymphoma in 10 hospitals were collected, including 77 cases in the imported group and 24 cases in the domestic group. The overall response rates were high in both groups, being 88.3% (68/77) in the imported group and 87.5% (21/24) in the domestic group, with no significant difference (P=1.00). The incidences of hematological toxicity (>grade 2) were low in both groups, being 1.3% (1/77) vs 8.3% (2/24), with no significant difference (P=0.14). Subgroup analysis was performed on the dosimetric parameters of organs at risk and acute toxicity of the two groups for extranodal nasal type NK/T cell lymphoma, and there were no significant differences in the maximal dose (Dmax) of the lens, Dmaxof the optic nerve, or mean dose (Dmean) of the parotid gland between the two groups (all P>0.05). However, there was an increasing trend in the domestic group compared with the imported group for Dmeanof bilateral parotid gland (left: [2 306.53±1 119.66] cGy vs[ 1 279.44±1 026.95] cGy, P=0.16; right:[ 2 328.35±1 009.76] cGy vs[ 1 303.79±1 116.79] cGy, P=0.17). The incidence of grade 2 xerostomia in the domestic group was higher than that in the imported group, but the difference was not statistically significant (50.0%[ 2/4] vs 14.3%[ 1/7], P>0.05). The domestic group had significantly lower radiotherapy cost [( 26 743.9±8 061.2] yuan vs[ 42 428.7±14 744.7] yuan) and total hospitalization cost [( 36 702.1± 12 225.8] yuan vs[ 50 192.7±15 494.4] yuan) than the imported group (both P<0.01). Conclusion There is no significant difference in the short-term efficacy of lymphoma treatment between the domestic radiotherapy equipment and the imported radiotherapy equipment, while the treatment cost of the domestic radiotherapy equipment is relatively low. However, the dosimetric parameters of organs at risk of imported radiotherapy equipment is lower and the acute toxicity is less..
