[Objective] To analyze the phenomena and characteristics of the mutations in 24 short tandem repeat (STR) loci. [Methods] A total of 5 084 parentage confirmed cases were analyzed. The mutation events were screened. The sources of mutant alleles were ascertained. The mutation rates of STR loci were calculated. The rule and feature of mutation were analyzed. [Results] A total of 172 mutation events were observed in 24 STR loci. The mutation rate was between 0-0.492%. The number of mutation loci was between 1 and 3 for 1 case. The mutation model was accordant with stepwise mutation model. The maximum mutation step was four. In addition, the ratio of paternal versus maternal mutation was 3.55:1. [Conclusion] STR mutation events were common in paternity testing. The information of mutated STR loci should be considered and included when calculating PI value.

Objective:To explore the regulatory effect of glutathione S-transferase P1(GSTP1) on the radiosensitivity of mouse Lewis lung cancer (LLC) cells.Methods:GSTP1-shRNA lentivirus and negative control lentivirus were used to respectively infect the LLC cells, and stable transgenic strains were selected. Real-time PCR and Western blot were conducted to quantitatively measure the expression levels of GSTP1 mRNA and protein in the LLC cells to verify the knockdown effect. The cell counting kit-8(CCK-8) assay was used to detect cell viability after irradiation. The colony formation assay was utilized to assess the cell proliferation ability after irradiation. Flow cytometry was performed to assess the level of cell apoptosis after irradiation. The tumor-bearing mice were established and irradiated to detect the changes in the tumor volume after irradiation. TUNEL staining was employed to detect the level of tumor apoptosis after irradiation. Immunofluorescence was used to detect the number of CD 4+ CD 8+ T cells in the tumor after irradiation. Results:Real-time PCR and Western blot showed that after shRNA lentivirus interference, the expression levels of GSTP1 mRNA and protein were significantly down-regulated. Down-regulation of GSTP1 reduced cell viability and proliferation, and increased the rate of cell apoptosis after irradiation. The tumor volume of the tumor-bearing mice after irradiation in the GSTP1 knockdown group was significantly smaller than that in the NC group, whereas the tumor apoptosis rate was significantly higher and the number of infiltrating CD 4+ CD 8+ T cells in the tumor was remarkably higher compared with those in the control group. Conclusion:Knockdown of GSTP1 can significantly increase the radiosensitivity of LLC cells and enhance the infiltration of lymphocytes in tumor tissues.

Background and objective Lung cancer is a serious threat to human health and its morbidity and mortality in recent years has always been ranked first in the country. Lung cancer patients are often associated with anxiety,depression and other emotional problems, and anxiety, depression and other emotional problems will further lead to a series of somatic symptoms. At present, we lack the clinical understanding of somatization symptoms in patients with lung cancer and related clinical studies are not too much. This research is to study the features of clinical manifestation of lung cancer patients with somatization symptoms and correlative analysis between anxiety, depression and somatization symptoms in medical on-cology department of general hospital. Methods Lung cancer patients who met somatization symptoms diagnostic standard were assessed with the self-constructed somatic symptoms investigation questionnaire, the Chinese version of the Patient Health Questionnaire-15 (PHQ-15) and anxiety and depression were recorded by the Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD). The detection rate of the anxiety, depression and the number of patients with different severity somatization symptoms were calculated, the relationship between the PHQ-15 scores and anxiety and/or depression and the distribution of the different frequency somatization symptoms were analyzed. Results There were 43 patients with anxiety and/or depression in the 50 lung cancer patients with somatization symptoms. Prevalence rates of anxiety, depression and anxiety combined with depression were 10%, 10% and 66% respectively. The more severity the somatization symptoms are, the higher detection rates of anxiety combined with depression are. Significant positive correlations were observed between PHQ-15 scores, PHQ-15 positive symptom numbers and HAMA scores (r=0.752, P<0.001; r=0.710, P<0.001), HAMD scores (r=0.648, P<0.001; r=0.618, P<0.001). The most common somatization symptoms were fatigue (96%), weakness (88%),sleep disturbance (84%), dizziness (82%), and pain in extremities (80%). There was no significant statistical difference in somatization symptoms between lung cancer patients with different gender (P>0.05). Conclusion Symptoms of anxiety or depression were very common in lung cancer patients with somatization symptoms and there was a close relationship between anxiety, depression, and somatization symptoms. The most common symptoms of these patients were nonspecific generalized symptoms.

Objective To explore the effect of low replacement plasma exchange(LPE)combined with double plasma molecular adsorption(DPMAS)in the treatment of patients with chronic acute liver failure(ACLF)and its influence on liver function,inflammatory cytokines and short-term prognosis.Methods One hundred patients with ACLF were randomly divided into the observation group and the control group by envelope method,with 50 cases in each group.On basis of routine symptomatic treatments(liver protection,removing jaundice,reducing enzymes,anti-viruses,bleeding prevention),the control group and the observation group were treated with plasma exchange(PE)and LPE plus DPMAS,respectively.The liver function,coagulation function,the levels of inflammatory cytokines,incidence of adverse reactions,and 90-day survival rate were compared between the two groups after treatment.Results After treatment,the liver function and coagulation function in the observation group were significantly improved(P＜0.05)and the levels of inflammatory cytokines were significantly lowered than those in the control group(P＜0.05).There was no statistically significant difference in the 90-day survival rate and the total incidence of adverse reactions between the groups(P＞0.05).Conclusion LPE combined with DPMAS can effectively improve liver function and coagulation function,and reduce levels of inflammatory cyto-kines in ACLF patients,with high safety.
