Chinese Journal of Pathophysiology 1986;0(04):-
This paper report the effects of hyperglucosemia and hypoinsulinemia on Immune system of alloxan diabetic mice. The results showed that the weight of thymus and spleen as well as the YAC-1 cell cleaning rate in the organs (lung, liver, blood) of the diabetic mice were significantly lower than that of the control. The proliferation response to Con A(2.5-20?g/ml) and the production of IL-2 of the lymphocytes were inhibi-ted markedly. When the lymphocytes were suspended in the culture medium containiny insulin, the proliferation response and the production of IL-2 increased markedly. These results suggested that the functions of lymphocytes and their natural killer activity were impaired in diabetic mice. Insulin is one of the important immunoregulation hormones and plays an important role in the regulation of immune system.

Objective To observe the effects of Tongbi Shuxin Granule on life quality of acute coronary syndrome (ACS) patients with anxiety and depression.Methods Ninety patients were randomly divided into the treatment group and control group through random number table method, 45 cases for each group. The control group was given fundamental treatment and emotional intervention, while the treatment group was given Tongbi Shuxin Granule additionally. On admission and 4th and 12th weeks, the scores of HAMA and HAMD were evaluated. On admission and 12th week, SAQ score was observed.Results In the 4th week, scores of HAMD and HAMA of two groups decreased compared with those on admission (P<0.05), with statistical significance (P<0.05). In the 12th week, scores of HAMD and HAMA of the control group were lower than those of 4th week, without statistical significance (P>0.05);the treatment group decreased significantly compared with on admission and 4th week (P<0.05), without statistical significance between the two groups (P<0.05). In the 12th week, all dimensions of SAQ score in the two groups increased compared with those on admission (P<0.05);the treatment group was much higher than the control group, especially the scores of physical limitation, angina stability and angina frequency (P<0.05).Conclusion Tongbi Shuxin Granule has the exact treatment effects on ACS patients with anxiety and depression.

The in vitro modulation effect of insulin on DNA and IL-2 production of spleen lymphocytes in diabetic mice were studied. The results suggest that the DNA and IL-2 production of the lymphoc-ytes are significantly inhibited in the mice. When suspend the lymphocytes to the culture medium containing insulin, the DNA and IL -2 production of the lymphocytes are remarkably increased. Therefore, insulin is an important immunoregulation hormone.

Positive linear correlation was found between TSH level and detection rate of congenital hypothyroidism (CH). When measured with a cut-off point at 9, 10, 15 and 20 mU/L of TSH, the sensitivity of positive detection rate for CH was 99.77%, 96.80%, 81.25% and 71.88%, respectively. TSH > 9 mU/L seems to be a reasonable cut-off value.

ObjectiveTo explore the screening and therapeutic efficacy of primary carnitine deficiency (PCD) in newborns and mothers.Methods164245 newborns and suspected mothers were investigated for PCD by tandem mass spectrometry (MS/MS).The overall epidemiology,prognosis,and follow-up of the screening program were investigated.ResultsTotally 55 suspected cases were identified at the primary screening stage.Four newborns and three mothers were confirmed as cases of PCD.The incidence rate of newborns was 1 ∶ 40076.All the patients showed normal growth and development during the follow-up.Blood free carnitine level was raised in all three mothers after treatment.ConclusionsScreening for PCD with MS/MS in newborns may represent a valuable procedure in preventive medicine by enabling early diagnosis and treatment before the onset of symptoms.This protocol is also highly efficient and applicable in diagnosis of mothers with PCD.

Objective To investigate the correlation between quantitative parameters of dynamic contrast?enhanced MRI (DCE?MRI) after neoadjuvant chemotherapy and pathological grades in esophageal squamous cell carcinoma. Methods Fifty?six patients with esophageal squamous cell carcinoma who were confirmed by esophagoscope and received neoadjuvant chemotherapy before operation between September 2015 and December 2017 in the Affiliated Cancer Hospital of Zhengzhou University were prospectively analyzed, and MRI examination was performed within one week before operation. All patients underwent routine chest MRI and DCE?MRI scanning, and quantitative parameters of DCE?MRI, including volume transfer constant (Ktrans),exchange rate constant (Kep) and extravascular extracellular volume fraction (Ve) were measured. Pathological grading was assessed as highly differentiated, moderately differentiated, poorly differentiated,and undifferentiated. Intraclass correlation coefficient (ICC) was calculated from the results of two radiologists. Kruskal?Wallis H test was used to compare the differences of quantitative parameters between different pathological grade groups of DCE?MRI,and Mann?Whitney U test was utilized to compare the intraclass differences among pathological grades. Spearman rank correlation analysis was performed for evaluating the correlation between DCE?MRI parameters and pathological grade of esophageal squamous cell carcinoma. The receiver operating characteristic (ROC) curves were used to evaluate the diagnosis accuracy of different DCE?MRI parameters in pathological grade of esophageal squamous cell carcinoma after neoadjuvant chemotherapy. Results The 56 patients were divided into four groups according to pathological findings: well differentiated group (n=8), moderately differentiated group (n=39), poorly differentiated group (n=9) and undifferentiated group (n=0). The differences of Ktransmean,Ktrans75%,Kepmax, Kepmean,Kep75% between different pathological grading groups were statistically significant (all P<0.05),and these parameters showed positive correlation significantly with pathological grading (r values were 0.778, 0.632, 0.594, 0.725, 0.489 respectively, all P<0.05). The ROC curve area of Ktransmean, Ktrans75% in the diagnosis of pathological grade for esophageal squamous cell carcinoma was 0.750,0.856,respectively. The diagnostic efficiency of Ktrans75% was the best with the diagnostic threshold of 0.693/min,sensitivity of 87.5%, specificity of 78.5%, respectively. Conclusion The quantitative parameters of DCE?MRI after neoadjuvant chemotherapy in esophageal squamous cell carcinoma have the potential value for predicting pathological grade.
