Objective To compare the changes of hs-CRP,IL-6 level,insulin secretion index (HOMA-β),insulin resistance index (HOMA-IR) in the different TCM Hou of type 2 diabetic patients.Methods 63 newly diagnosed type 2 diabetic patients were selected.According to the TCM syndrome,they were divided into combination of phlegm and heat,deficiency of both qi and yin,yin and yang deficiency three groups.20 healthy people were selected as control group.The serum hs-CRP,IL-6 and fasting blood glucose,insulin were measured.Results The levels of hs-CRP,IL-6 and insulin resistance index were lower than the other three groups,there were significant differences (t =6.948,P < 0.05).There was no significant difference in insulin secretion index between the control group and the combination of phlegm and heat gruop (t =4.832,P > 0.05).There were significant differences in IL-6 level and HOMA-β among different syndromes groups(t =4.985,5.043,P <0.05).HOMA-β from high to low was the combination of phlegm and heat group > deficiency of both qi and yin group > yin and yang deficiency group.Conclusion The change of IL-6 correlates with TCM syndromes,and the change of TCM syndrome with the change of islet function.IL-6 and insulin secretion index can be used as reference of TCM type.

Aim To investigate the effect of curcumin on radiosensitivity of radioresistant nasopharyngeal carcinoma cell line CNE-2R and its mechanism.Methods The concentration of curcumin was screened by MTT assay.Dose-survival curves were obtained according to the colony forming test for L-Q matching and multitarget-single hitting matching,while SF2 and the correlation parameters of radiation biology were calculated.The changes of cell cycle in CNE-2R cells caused by curcumin were also tested by flow cytometry(FCM).The differential expression of genes related to cell cycle and DNA damage repair were detected by RT-qPCR.Results CNE-2R cells could not be inhibited by 10 μmol·L-1 curcumin.Dealt with 10 μmol·L-1 curcumin for 24 h,the value of α/β increased to 1 596 from 6.56;the value of SF2 decreased to 0.361 Gy from 1.93 Gy;the value of N decreased to 1.06 from 1.60;the value of D0 decreased to 2.12 from 3.27;the value of Dq decreased to 0.12 from 1.53.FCM showed that the cells in G2 phase had a significant increase and the cells in S phase had a significant decrease after dealt with 10 μmol·L-1 curcumin for 24 h.The expression of CDK4 was significantly up-regulated and GADD45g,BRCA1 were significantly down-regulated.Conclusion Curcumin radiosensitizes nasopharyngeal carcinoma cell line CNE-2R by changing cell cycle and affecting DNA damage repair through regulating the expression of CDK4,GADD45 g and BRCA1.

OBJECTIVE:
To explore the value of in situ amniocyte culture for prenatal diagnosis.
METHODS:
2716 amniotic fluid samples were cultured in situ on slides. After the culture, the slides were stained, photographed and analyzed.
RESULTS:
All samples were successfully analyzed, with the success rates for primary culture and subculture being 98.42% and 1.58%, respectively. 224 samples (8.25%) were detected with chromosomal aberrations, which included 125 cases with trisomy 21, 31 with trisomy 18, 3 with trisomy 13, 4 with 45,X, 17 with 47,XXY, 5 with 47,XYY, 1 with 48,XXY,+18, 1 with 48,XXYY, 26 with structural chromosomal aberrations, and 11 with mosaicisms for aneuploidies.
CONCLUSION
In situ amniocyte culture is stable and has a high success rate, and is capable of identifying true and false mosaicisms, which can improve the accuracy of prenatal diagnosis.

Objective To compare the success rates of different culture methods for hemorrhagic amniotic fluid.Methods Thirty-one hemorrhagic amniotic fluid samples from pregnant women who were subjected to chromosomal examination at Anhui Maternal and Child Health Hospital were collected from January 2021 to December 2022.Two culture methods,the slide in situ culture box method(re-ferred to as the slide method)and the plastic bottle culture combined with slide in situ culture box method(referred to as the combined culture method),were used for cell cultivation.All the cells were harvested and stained with Giemsa staining,then the number of eligi-ble karyotype was counted and the success rates were compared between the two methods.Results Among the 31 cases of the slide method,21 were successfully cultured with a success rate of 67.7%.For the combined culture method,all the 31 cases were success-fully cultured with a success rate of 100%.The success rate of the combined culture method was significantly higher than that of the slide method(P<0.05).Of 31 bloody amniotic fluid samples,three cases were fresh bleeding,and an average number of eligible kary-otype was 8 in the slide method and 32 in the combined culture method.Twenty-eight cases were old bleeding,and an average number of eligible karyotype was 13 in the slide method and 53 in the combined culture method.The number of eligible karyotype in the com-bined culture method was significantly higher than that of the slide method(P<0.05).Conclusion The combined culture method is suitable for the cultivation of hemorrhagic amniotic fluid samples,and should be worthy of promotion in the clinics.
