Objective To investigate the clinical value of 6‐indicator of albumin ,alpha 1 globulin ,alpha 2 globulin ,beta 1 globu‐lin ,beta 2 globulin and gamma globulin detected by the automatic capillary serum protein electrophoresis in liver cancer disease . Methods Eighty‐three hospitalized patients(51 cases of primary liver cancer and 32 cases of secondary liver cancer) in our hospital from December 2014 to November 2015 were collected .The automatic biochemical analyzer and automatic capillary serum protein e‐lectrophoresis was adopted to detect the 8 indicators of serum albumin(g/L for quantitative indicator and % for qualitative indica‐tor) ,total protein ,alpha 1 globulin ,alpha 2 globulin ,beta 1 globulin ,beta 2 globulin ,gamma globulin .And 100 individuals undergo‐ing the healthy physical examination were randomly extracted as the control group .The levels of above 8 indicators were compared among various groups .Results The level of albumin(% ) and gamma globulin had statistical difference between the primary liver cancer group before treatment and the control group(P<0 .05);the levels of albumin(g/L) ,albumin(% ) ,beta 1 globulin and gam‐ma globulin had statistical difference between the primary liver cancer group after treatment and the control group(P<0 .05);the levels of albumin(g/L) and albumin(% ) after treatment in the primary liver cancer group were decreased compared with before treatment ,the difference was statistical difference(P<0 .05);the sensitivity and specificity of gamma globulin for indicating primary liver cancer were significantly higher than those of the other three indicators;at the same time in the comparison of the positive rate of serum gamma globulin ,the positive rate of serum gamma globulin in the primary liver cancer group was higher than that in the secondary liver cancer group and the control group(P<0 .05) .Conclusion The automatic capillary serum protein electrophoresis detection finds that gamma globulin has some clinical value in the diagnosis and treatment of liver cancer .

Objective To evaluate the value of intrathecal synthetic related markers in patients with mild cognitive impairment(MCI),Alzheimer's disease(AD),and other types of dementia.Methods Retrospec-tively collect the clinical data of 577 patients diagnosed with MCI(MCI group,178 cases),AD(AD group,131 cases),and other types of dementia(other types group,268 cases)from June 2019 to July 2023 in Beijing Tiantan Hospital,Capital Medical University.Oligoclonal zone electrophoresis(OCB)and 24 h intrathecal pro-tein synthesis rate(ISR)of each group were investigated,and the difference of different indexes among the groups was compared to evaluate the value of related indexes in the differential diagnosis of different diseases.Results Compared with AD group and other groups,AD group had a higher proportion of females,more patients were＞50-70 years old,and the incidence of abnormal lipid metabolism was higher,with statistical significance(P＜0.05).There were significant differences in OB(S),cerebrospinal fluid albumin,serum albumin and cerebrospinal flu-id IgG in different disease groups(P＜0.05).IgG index and ISR in patients with positive SOB(CSF)were higher than those in negative and weakly positive patients,and the differences were statistically significant(P＜0.001).IgG index was positively correlated with ISR(r=0.878,P＜0.001).Conclusion Intrathecal synthetic mark-ers such as IgG index,SOB(CSF)and 24 h ISR have synergistic effects in the diagnosis of cognitive dysfunction and various dementias,which can be collectively utilized in the diagnosis of diseases.
