Objective To investigate the effects of human IL-18 gene combined with diterpenoid alkaloids in inhibiting the proliferation and inducing the apoptosis of tongue squamous carcinoma cells Tscca.Methods We constructed recombinant plasmid pEGFPN3-IL-18 and tranfected it into tongue squamous carcinoma cells Tscca.The transduction efficiency of the target cells was detected by fluorescent microscopy,cytotoxic effect of IL-18 gene with diterpenoid alkaloids on Tscca was detected by MTT assay,and apoptosis was detected by flow cytometry. Western blot was employed to examine the expression level of cellular signal-regulated kinase Akt/p-Akt.Results The tongue squamous cells Tscca which transfected pEGFPN3-IL-18 had significantly increased apoptosis compared with non-transfected cells (P<0 .05 ).Tongue carcinoma squamous cells cultured with diterpenoid alkaloids at the concentrations of 0 .2 ,0 .4 and 0 .6 mg/mL had significantly increased apoptosis in a dose-dependent manner (P<0.05).Human IL-18 gene combined with diterpenoid alkaloids for 48 hours inhibited significantly Tscca in a concentration-dependent manner compared with diterpenoid alkaloids alone (P<0 .05 ).The two in combination could also decrease the protein level of p-Akt dose-dependently.Conclusion The combination of pEGFPN3-IL-18 and diterpenoid alkaloids has a synergistic effect in inhibiting the growth of tongue squamous carcinoma cells Tscca.

Colorectal cancer is a common clinical malignant tumor. As the main therapeutic method of colorectal cancer, radiotherapy has a good inhibitory effect on tumor progression. In recent years, because of its good physical and biological advantages, carbon ion has shown better clinical efficacy than traditional radiotherapy in the treatment of local recurrence or distant metastasis of colorectal cancer. In this article, basic and clinical studies related to the efficacy of carbon ion therapy for the recurrence of colorectal cancer in recent years were reviewed, aiming to provide theoretical basis for preventing and reducing adverse reactions after radiotherapy and prolonging the survival of colorectal cancer patients.

Objective To explore the effect and mechanism of microRNA (miR)-17-5p on the invasion and metastasis of hepatocellular carcinoma (HCC) cells. Methods Expression of miR-17-5p in the normal human L-02 hepatocyte and QGY-7703 HCC cells was detected by RT-PCR. QGY-7703 HCC cells were transfected by miR-17-5p mimic and mimic control respectively. Influence of miR-17-5p on the invasion and metastasis ability of HCC cells was detected using Transwell assay and scratch test. Target gene of miR-17-5p was confirmed by bioinformatic analysis, and its expression in HCC cells was detected by Western blot. After siRNA silenced by target gene, the invasion and metastasis ability of HCC cells were observed. Comparison of microRNA in the two kinds of cells was conducted by t test. Results Expression level of miR-17-5p in HCC cells was 0.16±0.04, significantly lower than 1.01±0.19 in normal L-02 hepatocytes (t=-9.67, P<0.05). Number of trans-membrane cells and metastasis rate of HCC cells transfected by miR-17-5p mimic were respectively 36±4 and (5.37±0.15) mm/d, significantly lower than 62±7 and (7.50±0.01) mm/d of control group (t=-15.40, -32.00; P<0.05). Bioinformatic analysis showed that AKT3 was the key target gene of miR-17-5p, and the expression of AKT3 in HCC cells was obviously higher than that of normal hepatocyte. Number of trans-membrane cells and metastasis rate of HCC cells transfected by siRNA-AKT3 were respectively 13±3 and (4.13±0.15) mm/d, significantly lower than 58±3 and (7.23±0.25) mm/d of control group (t=-17.88, -53.69; P<0.05). Conclusion miR-17-5p inhibits the invasion and metastasis ability of HCC cells through targeting effect on AKT3.

Objective:To evaluate the differences and aesthetic meaning of stable vitiligo treatment in the face and neck region using suction blister transplantation or noncultured autologous suspension of epidermal cells.Methods:Sixty-four stable vitiligo patients (25 males and 39 females with age ranges from 10 to 46 years, average 25 years) in the face and neck region were randomly divided into two groups (32 patients in each group): one group received suction blister transplantation, while other group received noncultured autologous suspension of epidermal cells. Patients′treatment effectiveness, pigmentation and piecing deformity were evaluated in postoperative 3 months and 6 months.Results:In the postoperative 3 months and 6 months, the effectiveness of suction blister transplantation group was 68.75% (22/32) and 90.63% (29/32), respectively, while the effectiveness of noncultured autologous suspension of epidermal cells group was 59.37% (19/32) and 87.50% (28/32), respectively, in which no significant differences were found between two groups ( P>0.05). No obvious pigmentation and piecing deformity were found in noncultured autologous suspension of epidermal cells group, which were much better than the suction blister transplantation group in postoperative 3 months and 6 months. Conclusions:Both suction blister transplantation and noncultured autologous suspension of epidermal cells could bring good treatment effectiveness for patients of stable vitiligo in the face and neck region. Compared with suction blister transplantation, noncultured autologous suspension of epidermal cells could offer better aesthetic appearance.

ObjectiveTo investigate the trends in diabetes mortality rate and the characteristics of decreased population in Fengxian District, Shanghai from 2012 to 2021. MethodsData from the death registration records of the residents in Fengxian District between 2012 and 2021, sourced from the Shanghai Death Surveillance System, were analyzed. Indicators such as the crude mortality rate due to diabetes, the standardized mortality rate, years of life lost (YLL), and the probability of premature death were estimated. Annual percentage change (APC) was used to analyze the temporal trends of mortality and the probability of premature death due to diabetes. Rate decomposition analysis was used to assess the contributions of demographic and non-demographic factors to diabetes mortality. ResultsFrom 2012 to 2021, there were 1 471 deaths due to diabetes in Fengxian District, with a crude mortality rate of 27.51/100 000 and a standardized mortality rate of 17.58/100 000. The crude mortality rate showed an overall increasing trend (APC=4.58%, Z=3.49, P<0.05). The potential years of life lost (PYLL) due to diabetes over this period amounted to 9 715 person-years, with a PYLL rate of 1.82 ‰, and the average years of life lost (AYLL) was 11.94 years. The probability of premature death was 0.41% (APC=3.36%, t=2.33, P<0.05). Both population aging and non-aging factors contributed to the increase in diabetes mortality, with overall contribution rates of 67.99% and 32.01%, respectively. Among men, the contribution rates were 60.57% and 39.43%, while among women, they were 79.43% and 20.57%, respectively. ConclusionFrom 2012 to 2021, both the crude mortality rate and the probability of premature death due to diabetes showed an upward trend among the residents in Fengxian District, with a higher YLL. Population aging was the main factor causing the increase in mortality rate, while non-demographic factors had a greater impact on the rise in diabetes mortality among men than that in women. Therefore, the management on male diabetes patients should be strengthened.

Hepatocellular carcinoma is one of the common causes of tumor-related death, and it has high morbidity and mortality rates in China. Recent studies have shown that platelets are closely associated with the development of hepatocellular carcinoma. Literature review shows that platelets not only participate in hemostasis, but also act on liver cells and tumor microenvironment, promote the formation of new blood vessels, and participate in the development and progression of hepatocellular carcinoma as a cell mediator through immune response and other pathways. In addition, platelets and their derivatives can be used as potential therapeutic targets for hepatocellular carcinoma. Therefore, antiplatelet therapy is expected to become a new adjuvant strategy for the treatment of hepatocellular carcinoma, which has important clinical significance.
