Tianjin Medical Journal 2014;(7):638-640
Objective To investigate the effect of cisplatin on proliferation and invasion of colorectal cancer cell line SW480. Methods SW480 cells were used as the research object, and untreated SW480 cells were used as the control group. Different concentrations of cisplatin was given at different times to intervene. The MTT, Transwell chamber and phos-phate determination methods were used to detect proliferation, invasion and Na+-K+-ATPase activity expression level in SW480 cells. Results The physiological concentration of cisplatin (70 μmol/L) inhibited the proliferation of SW480 cells at 48 h. There was no significant difference in the inhibition rate at 48 h compared with 72 h and 96 h. Treatment with 70 μmol/L cisplatin for 48 h reduced the number of cells through Matrigel membrane matrix. The Na+-K+-ATPase activity was significantly increased in 35, 70 and 140 μmol/L cells after treatment with 17.5, 35, 70 and 140 μmol/L of cisplatin in SW480 cells for 48 h, and Na+-K+-ATPase reached the highest level at 70 μmol/L of cisplatin. Conclusion The decreased activity of Na+-K+-ATPase may lead to the attenuation in proliferation and invasion of colorectal cancer cells, which may be associated with cisplatin resistance in colorectal cancer cell SW480.

Journal of Preventive Medicine 2025;37(1):65-68
Objective:
To investigate the epidemiological characteristics of rubella in Wuxi City, Jiangsu Province from 2015 to 2023, so as to provide the basis for rubella prevention and control.
Methods:
Data of rubella surveillance cases and laboratory tests were collected through the Chinese Measles Surveillance Information Report Management System. The temporal, regional and demographic distribution of confirmed rubella cases were analyzed using the descriptive epidemiological method.
Results:
A total of 2 167 rubella surveillance cases were reported in Wuxi City from 2015 to 2023, including 154 confirmed rubella cases, with an average annual reported incidence of 0.25/105. All the confirmed cases were laboratory-confirmed, and the positive rate of laboratory testing was 7.11%. The main clinical symptoms were rash (96.75%) and fever (86.36%). The incidence of rubella peaked in 2015 and 2019, with sporadic cases in other years. Rubella incidence exhibited a distinct seasonal pattern, and the prevalent months were from February to May. Xishan District and Huishan District had the higher reported incidences, at 0.44/105 and 0.42/105, respectively. There were 101 male confirmed rubella cases and 53 female cases, with a male-to-female ratio of 1.91∶1. The incidence was higher in males than in females (0.32/105 vs. 0.18/105, P<0.05). The majority of cases were aged 19 to <46 years, with 112 cases accounting for 72.73%. There were 43 workers (27.92%) and 27 housekeepers and unemployed individuals (17.53%). The rubella containing vaccine immunization rate among the confirmed rubella cases was 12.99%, which was lower than the 36.20% among the cases excluding measles and rubella (P<0.05). The majority of the individuals aged 19 years and above had unknown immunization histories.
Conclusions
The reported incidence of rubella in Wuxi City remained low from 2015 to 2023. The disease was prevalent in winter and spring, and the cases mainly distributed in Xishan District and Huishan District. Individuals aged 19 to <46 years, males and workers were key populations for prevention and control.

7.Research progress of long non-coding RNAs in colorectal cancer
Journal of Medical Postgraduates 2016;29(5):556-560
Long non-coding RNAs ( LncRNAs) are a class of RNA transcripts greater than 200 nt in length without the func-tion of protein encoding.LncRNAs, which consist of a great variety of categories and structures, regulate the associated gene expression on multiple levels, including chromatin modification, transcriptional and post-transcriptional regulation, and epigenetic modification. Moreover, LncRNAs are widely involved in the physiological and pathological processes.Recently, a large number of studies have found that the abnormal expression of LncRNAs is closely related to the occurrence, development, invasion and metastasis of tumor, and plays an essential role in pathogensis of colorectal cancer.In this paper, the function of LncRNAs in colorectal cancer is reviewed, which provides a theoretical evidence for its use in the diagnosis and treatment of colorectal cancer in clinical study.

Chinese Journal of Applied Clinical Pediatrics 2016;31(17):1336-1338
Objective To observe the characteristics of electrocardiographic parameters of the right heart in the early newborns with different gestational age.Methods Seventy-five cases of early newborns from January 2014 to January 2015 were selected.They were divided into 4 groups according to gestational age,15 cases in group A (28-30 weeks),18 cases in group B (>30-33 weeks),17 cases in group C (>33-37 weeks) and 25 cases in group D (> 37-40 weeks).All newborns were examined by the synchronous 12-lead ECG machine,and the changes in ECG time limit detection results,QRS amplitude and RV1 amplitude were compared among groups.Results (1) There was a significant difference in P-R intervals among group A [(0.090 ± 0.011) s],group B [(0.095 ± 0.012) s],group C [(0.098 ± 0.013) s] and group D [(0.105 ± 0.014) s] (F =7.458,P < 0.05).The P-R intervals of group A,group B and group C were much shorter than those of group D (P < 0.05);the comparison of QRS duration and QTc among groups had no statistical significance (F =1.626,1.569,all P > 0.05).(2) In group A:QRS amplitude was:(4.430 ± 1.380) mV,RV1 amplitude:(0.850 ± 0.420) mV;in group B:QRS amplitude was:(4.800 ± 1.350) mV,RV1 amplitude:(1.012 ± 0.425) mV;in group C:QRS amplitude was:(5.200 ± 1.600) mV,RV1 amplitude:(1.210 ± 0.520) mV;in group D:QRS amplitude was:(5.800 ± 1.800) mV,RV1 amplitude:(1.509 ± 0.525) mV.There were significant differences in QRS and RV1 amplitude among 4 groups (F =7.002,16.870,all P < 0.05).The QRS amplitude changes in group A and group C were far less than those in group D (P < 0.05),the RV1 amplitude changes in group A,group B,and group C were far less than those in group D (P < 0.05),and there was no difference between among other groups (all P > 0.05).Conclusions There are correlations between the electrocardiographic parameters of right heart and the gestational age of newborn infants.These parameters,including the P-R intervals,the amplitude of QRS and RV1,increase with the gestational age.
10.Research progress of chimeric antigen receptor-transduced-T cells in B-cell malignancies
Journal of Leukemia & Lymphoma 2014;23(12):757-760
Chimeric antigen receptor-transduced-T (CAR-T) cells shows strong cytotoxicity to the tumor with specific antigen by CTL effects and cytokines releasing without MHC-restriction.As multiple clinical trials from cancer centers around the West countries reported recent years,anti-CD19-CAR T cells can not only induce complete remission of B-cell malignancies resistant,but also eliminate the minimal residual disease (MRD) at the molecular level.It is believed that the obstacles from bench to clinic will be cleared and CAR will become one of the main cancer therapies with breakthroughs in comprehensive treatment of tumors.
