Objective To investigate the treatment of acute obstructive colorectal cancer.Methods The clinical data of 26 cases with acute obstructive colorectal cancer were analysed retrospectively and relevant literatures were reviewed.Results Radical right hemicolectomy was performed in 9 patients with obstructive right colonic cancer.Among 17 patients with obstructive left colorectal cancer,one-stage radical resection was perfomed in 12 cases,including one-stage anastomosis in 4 cases and Hartmann's operation in 8 cases.Palliative colostomy was performed in 3 cases.Right hemicolectomy and sigmoid colon loop colostomy was performed in 1 case of rectum cancer with ascending colon strangulation.One case refused surgery.Two cases died of MODS and 1 case with inflammatory ileus recovering from conservative treatment after operation.In the course of disease,septic shock and MODS happened in 3 cases,lung infection in 5 cases,heart disease in 2 cases and Hypoalbuminemia in 16 cases.Conclusions One-stage radical colectomy and anastomosis should be performed in patients with obstructive right colonic cancer.In order to reduce toxin absorption and prevent the deterioration of disease,Bowel decompression and removal of inflammatory exudate should be performed in patients with obstructive left colorectal cancer according to the damage control theory.Then effective and safe operation should be chosen in accordance with patients' status.Anti-infection and nutrition support treatment must be strengthened after operation.

Objective:To evaluate the clinical effect of minimally invasive extraction of impacted supernumerary teeth.Methods :35 cases of impacted supernumerary teeth were included.Excluding extraction contraindications,preoperative X-ray or dental CT examina-tion was executed to find out the location of the impacted teeth and adjacent anatomical structures.According to the location,operation approach was selected to extract the impacted supernumerary teeth using minimally invasive apparatus.Intraoperative and postoperative feeling of the patients and the complications were recorded.Results:Operation time lasted from 1 0 to 40 minutes,average 1 5 minutes. All patients maintained good comfort in the operation.8.6% patients had postoperative adverse reactions such as mild pain and discom-fort.None had serious reactions.Conclusion:Minimally invasive extraction of impacted supernumerary teeth has less complication and less uncomfort.

OBJECTIVE: To test the reliability and validity of Health Scale of Traditional Chinese Medicine (HSTCM) by means of questionnaires. METHODS: A cross-sectional survey was conducted at Liwan Community of Guangzhou, Old People's Home in Guangzhou and Outpatient Department of the Second Affiliated Hospital of Guangzhou University of Chinese Medicine. A total of 652 Chinese individuals (over 18 years old) were assessed with the 88-item version of HSTCM and World Health Organization Quality of Life Measure-Abbreviated Version (WHOQOL-BREF), which were randomly delivered to them. Some socioeconomic characteristics were registered. RESULTS: A test-retest reliability (15-day interval) was found among the 76 persons who completed the questionnaires by themselves. Intra-class correlation coefficient (ICC) was 0.93. Associated 95% confidence interval (CI) was 0.89-0.96. Split-half reliability was 0.79. Inter-investigator reliability (0.93) was also good, and the ICC of HSTCM was 0.90 (95%CI 0.67-0.97). The correlation between HSTCM and WHOQOL-BREF was -0.66. The correlations of HSTCM and questionnaire deliver order, investigator, interview date and interview time were 0.06, -0.12, -0.17 and 0.20 respectively. The correlation between HSTCM and self-rated health (0.46) was greater than that between HSTCM and chronic illness (0.28). Divided by individuals with or without chronic illness, area under the ROC (receiver operator characteristic) curve for HSTCM was 0.67 (95%CI 0.63-0.71). CONCLUSION: It indicates that the HSTCM is conceptually valid with satisfactory psychometric properties and forms a basis for further applications in clinical research of traditional or integrative medicine.

Objective:To explore the effect of extracorporeal shock wave combined with meloxicam tablets on joint function and serum matrix metalloproteinase-9 (MMP-9) and resistin levels in elderly patients with osteoarthritis.Methods:80 cases of elderly patients with osteoarthritis in Nanchong Central Hospital from May 2016 to March 2019 were selected as the research objects, and they were randomly divided into two groups, 40 cases in each group. The control group was given conventional oral medicine (meloxicam + potassium glucosamine sulfate tablets), and the observation group was given meloxicam tablets combined with extracorporeal shock wave therapy. The total effective rate, incidence of adverse reactions, and the scores of osteoarthritis symptoms (WOMCA), joint function (Lysholm), serum MMP-9 and resistin before and after 8 weeks' treatment were compared between the two groups.Results:After treatment, the WOMCA score of the observation group was lower than that of the control group, and Lysholm score was higher than that of the control group ( P<0.05); the total effective rate of the observation group (95.00%) was higher than of the control group (77.50%) ( P<0.05); the serum resistin and MMP-9 levels of the observation group were lower than those of the control group after treatment ( P<0.05); there was no significant difference in the incidence of adverse reactions between the observation group (15.00%) and the control group (17.50%) ( P>0.05). Conclusions:Extracorporeal shock wave combined with meloxicam tablets in the treatment of elderly patients with osteoarthritis can significantly improve the clinical symptoms, promote the recovery of joint function, reduce the levels of serum resistin and MMP-9, and further improve the treatment effect with high safety.

BackgroundResearches demonstrated that the levels of soluble CD44 (sCD44)molecule in aqueous is significantly higher in primary open-angle glaucomous(POAG) eye than normal eye,but how the sCD44 would affect the expression of apoptosis protein in trabecular meshwork cells is below understanding.Objective The present study was to investigate the effect of sCD44 on the expression of regulatory proteins bcl-2 associated death factor bad in trabecular meshwork cells in the patients with POAG.MethodsHuman scleral tissue with trabecular meshwork were obtained from POAG patients during the surgery.The trabecular meshwork cells were primarily cultured by explant culture method and identified by immunochemistry.The third generation of cells were incubated with free-serum DMEM/F12 medium added differnt dosages of sCD44 (0,1,5,10,25,50 mg/L) for 48 hours.The expression of bad protein in cultured cells was detected using cell counting kit-8 (CCK-8) as the absorbance values at 490 nm(A,90 value),and the bad protein level in cultured cells was assayed by ELISA.ResultsThe cultured cells showed the positive response for laminin ( LM ),neuron specific enolase ( NSE ),fibronectin ( FN ) monoclonal antibodies.The CCK-8 assay showed that the A490 values of the trabecular meshwork cells in 0,1,5,10,25,50 μg/L of sCD44 groups were 0.2460±0.0019,0.1874±0.0015,0.1570±0.0016,0.1302±0.0019,0.1084±0.0018,0.0940±0.0020 respectively with a statistically significant difference among the 6 groups( F =14.922,P =0.000 ),and the A490 values in various dosages of sCD44 groups were significantly lower than the 0 μg/L sCD44 group (P=0.013,0.008,0.011,0.005,0.004).The ELISA assay showed that bad protein levels in 0,1,5,10,25,50 μg/L of sCD44 groups were ( 114.8461 ± 2.9560 ),( 137.8270 ± 2.4259 ),( 161.4194 ± 3.7381 ),( 170.9453 ± 3.2006 ),( 221.2252 ±4.3738 ),( 324.6167±4.4220) ng/L,showing a total difference among them ( F =16.610,P =0.000 ),and the bad protein levels in various dosages of sCD44 groups were significantly lower than the 0 μg/L sCD44 group( P =0.017,0.013,0.008,0.007,0.006).ConclusionssCD44 can contribute to the apoptosis of the trabecular meshwork cells in patients with POAG in certain dose range by regulating the apoptosis regulatory proteins bcl-2 associated death factor bad.

Objective To investigate the protective effects and the mechanisms of 17β-estradiol on the propofol-induced neuroapoptosis in primary cultured rat cortical neurons.Methods The neurons were cultured for 7 days and then divided into three groups: vehicle-control group ( treated with equal volume of 20% intralipid ) , propofol-treated group ( treated with 500μmol/L propofol) , and propofol plus 17β-estradiol treated group ( treated with 500μmol/L propofol and 0.1 μmol/L 17β-estradiol).12 hours after the treatment, neuroapoptosis was detected by Hoechst 33258 staining and TUNEL assay, and the levels of Bcl-2, Bax and cleaved caspase-3 proteins were detected by Western blot.Results Compared with the vehicle-control group, the neuroapoptosis increased greatly ( P<0.01 ) , Bcl-2 level reduced ( P <0.01), Bax and cleaved caspase-3 levels increased greatly (P<0.01), and Bcl-2/Bax ratio reduced significantly (P<0.01).Compared with the propofol-treatment group, the neuroapoptosis decreased greatly ( P <0.01), Bcl-2 level increased ( P<0.01 ) , Bax and cleaved caspase-3 levels reduced greatly ( P <0.01 ) , and Bcl-2/Bax ratio increased greatly ( P <0.01 ) . Conclusions 17β-estradiol can protect cortical neurons against propofol-induced cortical neuroapoptosis by regulating the expression of Bcl-2 and Bax.

Objective To explore the effects of iPS cells-derived chimeric thymus transplantation on T cells reconstitution and graft versus host disease of murine after allo-BMT. Methods iPS cells-derived chimeric thymus was grafted under the renal capsules of mice after allogeneic IBM-BMT. The mice were divided into three groups:IBM-BMT group, IBM-BMT+TT group and IBM-BMT+DLI group. Four weeks after BMT, T lymphocyte subsets in the peripheral blood were analyzed by flow cytometry, the degree and pathological examination of GVHD were observed, respectively. Results Percentage of CD8+T cells in IBM-BMT group, IBM-BMT+TT group and IBM-BMT+DLI group was(5.52 ± 0.83)%,(11.10 ± 1.49)%and(8.49 ± 0.82)%respectively, there was signifi-cant difference between pairwise comparisons(P<0.05), and percentage of CD4 + T cells of the peripheral blood in IBM-BMT+TT group(9.60 ± 0.69)%was significantly higher than IBM-BMT group(6.42 ± 1.40)%and IBM-BMT+DLI group(8.07 ± 0.65)%(P<0.05) . IBM-BMT group and IBM-BMT+TT group showed less clinical and histopathological scoring of GVHD than IBM-BMT + DLI group. Conclusion iPS cells-derived chimeric thymus transplantation could effectively accelerate T cells reconstitution and prevent GVHD after allo-BMT.
