Objective:To evaluate the effect of high intensity interval training on cancer patients.Methods:Web of Science, EBSCO, PubMed, Ovid, EMbase, Cochrane Library, CBM, CNKI and Wanfang database were searched for randomized controlled trials of the effect of high intensity interval training on cancer patients, RevMan5.3 software was used for analysis.Results:Eleven articles with a population of 614 were included in the analysis, which involved 323 cases of the intervention group and 291 cases of the control group. The analysis showed that high intensity interval training could improve the total quality of life ( SMD values were 0.40, 95% CI 0.14-0.65, P<0.01) and peak oxygen uptake ( MD values were 3.00, 95% CI 2.19-3.80, P<0.01) of cancer patients, and reduce carotid intima-media thickness ( MD values were -0.06, 95% CI-0.08--0.03, P<0.01), but did not reduce the high-sensitivity C-reactive protein ( MD values were -0.61, 95% CI-1.23-0.01, P>0.05) and body weight ( MD values were 0.16, 95% CI-3.19-3.51, P>0.05). Conclusions:High intensity interval training has a positive impact on quality of life, cardiopulmonary function and carotid intima-media thickness with cancer patients, but has no significant effects on high-sensitivity C-reactive protein and body weight.

Objective To investigate the dose-effect relationship between Q-switch ruby laser and skin pigmentation in Guinea pigs. Methods Ten Guinea pigs were included in this study, and the back of each pig was divided into 5 areas, negative control area receiving no UVB irradiation or laser treatment, positive control area receiving UVB irradiation but no laser treatment, low-, middle- and high-dose areas receiving UVB irradiation followed by the treatment with laser at an energy density of 1.5, 3.0 and 6.0 J/cm2 for 4, 2, and 1 session, respectively, with an interval of 1 week. Melanin content index (MCI) was determined, and confocal laser scanning microscopy (CLSM) and histopathology were performed to observe melanin granules and melanocytes in the skin tissue from Guinea pigs before the initial laser treatment, 2 and 4 weeks after the final laser treatment. Results The best response was observed in the low-dose areas, and there was a complete clearance of hyperpigmentation in these areas, which maintained 8 weeks without recurrence, while different degrees of skin pigmentation recurred in the middle- and high-dose areas. Moreover, the low-dose areas showed a significantly lower melanin content index (MCI) compared with the middle- and high-dose areas (F = 4.2,P < 0.05), together with a marked reduction in the extent of pigment deposition, melanin granules, melanocyte number and density. Conclusions The efficacy of Q-switched ruby laser on skin pigmentation in Guinea pigs is correlated with the energy density and treatment frequency, and, low intensity and high frequency are often associated with a better treatment outcome.

A 27-year-old man presented with a 3-year history of persistent asymptomatic papules on the left chest and axirlary fossa. Multiple skin biopsies were performed and histopathology revealed mild acanthosis, extension of the dermal papilla, lichenoid lymphoid infiltrates in upper dermis. Some lymphoid cells migrated into the epidermis and formed Pautrier's microabscesses. Immunohistochemistry revealed that the infiltrating cells were positive for LCA, CD45RO, CD3, CD4 and CD8 (scattered), but negative for CD68 or CD30. Cutaneous laser confocal microscopy showed the shadow of scattered, oval or round, slightly refractive cells measuring 4-8 pm in diameter. A diagnosis of papular mycosis fungoides was made. The papules were softened with the lightening of lesional color after treatment with narrow-band ultraviolet B, topical fluticasone propionate cream and isotretinoin gel.

Objective To evaluate the efficacy of Disposcope endoscope for tracheal intubation in patients with difficult glottis exposure.Methods Sixty adult patients of both sexes,aged 22-68 yr,scheduled for elective oro-tracheal intubation under general anesthesia,whose glottis was not visible under Macintosh laryngoscope (grade Ⅲ or according to Cormach-Lehane Grading of laryngoscopic view),were randomized into 2 groups (n =30 each) using a random number table:group Macintosh laryngoscope-assisted Disposcope endoscope (group DM) and group Disposcope endoscope (group D).The glottis exposure condition and time,intubation condition and time,assisted lifting mandible,laryngeal mucosa bleeding and postoperative sore throat and hoarseness were recorded.Results The success rate of intubation at second attempt achieved 100％ in the two groups.Compared with group DM,the incidence of assisted lifting mandible was decreased,and no significant changes were found in the success rate of glottis exposure,glottis exposure time,intubation time,success rate of intubation at first attempt,incidence of laryngeal mucosa bleeding,and postoperative sore throat and hoarseness in group D.Conclusion Disposcope endoscope can improve the condition for tracheal intubation significantly after lifting mandible in patients with difficult glottis exposure.

Objective:To compare the efficacy of domestic and imported hemostatic clips in preventing delayed post-polypectomy bleeding (DPPB) after endoscopic resection of colorectal polyps ≥ 10 mm.Methods:Clinical data of 789 patients who underwent endoscopic resection of colorectal polyps (polyp diameter ≥10 mm) in Beijing Friendship Hospital, Capital Medical University from January 2018 to December 2019 were collected. The patients were divided into DPPB group ( n=15) and non-DPPB group ( n=774). Univariate and multivariate logistic regression models were used to analyze the influential factors for DPPB. The patients using one type of hemostatic clip were divided into the domestic hemostatic clip group ( n=499) and the imported hemostatic clip group ( n=208). The efficacy of hemostatic clips in preventing DPPB in the two groups was compared. Results:Among the 789 patients undergoing endoscopic resection of colorectal polyps, 1.9% (15/789) suffered from DPPB. Multivariate logistic regression analysis showed that pedunculated polyp was an independent risk factor for DPPB ( OR=6.621, 95% CI: 2.278-19.241, P=0.001), and closure of mucosal defect was an independent protective factor for DPPB ( OR=0.169,95% CI: 0.050-0.570, P=0.004). Regardless of physician experience, there was no significant difference between the domestic and imported hemostatic clip group in preventing DPPB after endoscopic resection of colorectal polyps ≥10 mm [experienced physicians: 1.8% (7/385) VS 0.6% (1/175), χ2=1.314, P=0.445; common physicians: 2.6% (3/114) VS 3.0% (1/33), χ2=0.010, P>0.999]. The domestic hemostatic clip group paid for less medical expenses than the imported hemostatic clip group (experienced physicians: 1 433.51±889.02 yuan VS 3 033.97±1 686.87 yuan, t<0.001 , P<0.001; common physicians: 1 181.58±815.29 yuan VS 3 303.46±1 690.43 yuan, t<0.001 ,P<0.001). Conclusion:Pedunculated polyp is an independent risk factor for DPPB after endoscopic resection of colorectal polyp larger than 10 mm, and clipping can significantly reduce the risk for DPPB. There is no significant difference in the prevention of DPPB between domestic and imported clips, but domestic clips compared with imported clips yield less medical burden, which are suitable for promotion to primary hospitals and major clinical centers.
