Objective:To explore effects of multidisciplinary collaborative continuous care based on WeChat platform on peri-implant tissue of patients with periodontitis.Methods:Stratified sampling was used to select 100 patients with chronic periodontitis who underwent periodontal treatment in Stomatology Center of Shenzhen People's Hospital from March 2019 to March 2020, and their periodontal status was stable and implant restoration was completed. According to admission time, they were divided into the observation group (50 cases, 82 implants) and the control group (50 cases, 78 implants) . The observation group was given continuous care mode of multidisciplinary cooperation based on WeChat platform, while the control group was carried out the conventional continuous care intervention. At 0, 3, 9 and 12 months after completion of implant restoration, the peri-implant index of patients in the two groups were evaluated, including plaque index, periodontal pocket depth and probing bleeding index.Results:Within 12 months after implant restoration, the plaque index of the observation group showed a decreasing trend, while that of the control group showed an increasing trend. At 6 and 12 months after repair, the plaque index of the observation group were lower than that of the control group, and the differences were statistically significant ( P<0.05) . Within 12 months of completion of implant restoration, the depth of periodontal pockets in both groups showed an increasing trend. At 3, 6, and 12 months after the restoration, the depth of periodontal pocket in the observation group were lower than that in the control group, and the differences were statistically significant ( P<0.05) . At 12 months after implant restoration, the exploratory bleeding index of the observation group and the control group was respectively 10.22 (0, 19.98) % and 34.23 (16.12, 43.23) %, and the difference between the two groups was statistically significant ( P<0.05) . Conclusions:Multidisciplinary collaborative continuous care based on the WeChat platform can effectively control various periodontal indexes of implants in patients with chronic periodontitis, maintain the health of periodontal tissues and help prevent the occurrence of peri-implantitis.

Objective: To investigate the efficacy and safety of using pegylated recombinant human granulocyte-colonystimulating factor (PEG-rhG-CSF) in preventing neutropenia in multiple chemotherapy cycles. Methods: A multicenter, prospective, open-label, singlearmstudy was designed. Patients with malignant tumors, such as lung, ovarian, and colorectal cancers, who received multiple cycles of chemotherapy with the prophylactic use of PEG-rhG-CSF for 2-4 consecutive cycles participated in the study. Results: After the prophylactic use of PEG-rhG-CSF, the incidence of grade IV neutropenia decreased from 4.76% (13/273) in the first cycle to 1.83% (5/273), 1.15% (2/174), and 2.08% (2/96) in subsequent cycles. Meanwhile, the incidence of grade III neutropenia decreased from 11.36% (31/ 273) in the first cycle to 6.23% (17/273), 2.87% (5/174), and 3.13% (3/96) in subsequent cycles. The incidence of febrile neutropenia (FN) during the first cycle was 0.73% (2/273). The duration of FN was 2 days in one case and 5 days in another case. FN was not observed during the second, third, or fourth cycle. After the secondary prophylactic use of PEG-rhG-CSF, the incidence of grade IV neutropenia decreased from 25% (7/28) to 3.57% (1/28), 0% (0/28), and 6.67% (1/15) in subsequent cycles. Meanwhile, the incidence of grade III neutropenia decreased from 71.43% (20/28) to 10.71% (3/28), 14.29% (4/28), and 0% (0/15) in subsequent cycles. The proportion of patients who received antibiotic therapy during the entire chemotherapy period was 10.48% (44/420). Conclusion: The application of PEG-rhG-CSF once per chemotherapy cycle can effectively reduce the occurrence of neutropenia in patients under multiple cycles of chemotherapy treatment with good safety.

Objective:To explore the mechanism of the cytotoxicity of human NK cells induced by atorvastatin to colon cancer cell lines. Methods:After colon cancer cells (HCT-116,SW-480,Caco-2) were cultured with different concentrations of atorvastatin, CCK-8 assay was used to assess the effect of atorvastatin on growth of colon cancer cells. The amplification of human NK cells was induced by SCGM medium in vitro. Automatic biochemical analyzer was applied to test the cytotoxicity of NK cells to colon cancer cells which cultured with different concentration of atorvastatin. FCM was used to detect the expression rate of MICA/B on the cells. Results:(1) The cultivation of NK cells:The proportion of NK cells attained to 93. 1% from 4. 5% after cultured for 10 days. (2) The effects of atorvastatin on the growth of the colon cancer cells:After cultured with atorvastatin,the inhibition rate of HCT-116 cells was higher than that in control when the density of atorvastatin increased from 5 μmol/L to 40 μmol/L after 48 h and from 1. 25 μmol/L to 40 μmol/L after 96 h ( P<0. 05 ) . Correlation analysis showed that the concentration of atorvastatin and the growth inhibition rate of HCT-116 cells were positively correlated(r[48 h]=0. 13,r[96 h]=0. 22,P<0. 05). (3) The cytotoxicity of NK cells to colon cancer cells effected after atorvastatin: In different atorvastatin concentrations groups,the cytotoxicity of NK cells to three colon cancer cell lines was all higher than that in control ( P<0. 05 ) . The atorvastatin concentration was from 2. 5 μmol/L to 10 μmol/L for HCT-116 cells,from 5 μmol/L to 20μmol/L for SW-480 cells,and from 2. 5μmol/L to 20μmol/L for Caco-2 cells. Among the three cell lines, the cytotoxicity of NK cells to HCT116 was the highest in the same concentration. (4)NK cells by atorvastatin cutting statins 96 h,the concentration of 20 mmol/L and 40 mmol/L inhibition rate was higher than that of control group,more than other groups on NK cell growth without significant effect. ( 5 ) The impact of atorvastatin on MICA/B expression of colon cancer cells: After cultured with different concentrations of atorvastatin,the expression of MICA/B on colon cancer cells was higher than that in control(P<0. 05). The concentration was 2. 5μmol/L and 5μmol/L for HCT-116 cells,10μmol/L and 20μmol/L for SW-480 cells,and from 2. 5μmol/L to 40 μmol/L for Caco-2 cells. Conclusion:Atorvastatin could inhibit the growth of colon cancer cells (HCT-116,SW-480 and Caco-2) in a dose-dependent manner;and it could enhance the cytotoxicity of NK cells to colon cancer cells;it also could promote the expression of MICA/B of colon cancer cells,and improve the immunogenicity of colon cancer cells.
