Objective To discuss effects of thoracoscopic lobectomy on early-stage non-small cell lung cancer . Methods 60 patients with non-small cell lung cancer patients were randomly divided into two groups of 30 cases in each group using thoracoscopic lobectomy (VATS) treatment,as the VATS group,another group using traditional open surgery(TOS) therapy,TOS as a group.(1) Operative time,blood loss,postoperative drainage time,drainage, postoperative pain,postoperative bed days,after several days of hospitalization were compared between the two groups . (2) 1,3 and 5 days after surgery,serum C-reactive protein(CRP) and interleukin-6(IL-6)levels were compared. Results (1)were operative time,postoperative drainage time,pain time,bed time and hospitalization time in VATS group were (69.50 ±15.33)min,(60.23 ±9.75)h,(46.75 ±7.36)h,(3.54 ±1.58)d,(9.50 ±2.50)d,com-pared with TOS group (86.77 ±19.56)min,(66.50 ±10.50)h,(58.36 ±9.58)h,(5.50 ±1.55)d,(13.55 ± 3.18)d short d observed group blood loss ,drainage volume(161.55 ±25.54)mL,(155.75 ±23.18)mL,compared with TOS group(186.58 ±25.35)mL,(169.65 ±26.87)mL less,the difference was statistically significant (t =39.14,28.19,54.11,6.03,7.24,98.36,76.34,all P<0.05).(2) VATS group after 1,3 and 5 days CRP serum and were(79.58 ±22.15) mg/L,(97.23 ±28.16) mg/L,(98.44 ±27.19) mg/L,IL-6,respectively (69.36 ± 17.32) ng/L, ( 96.33 ±25.67 ) ng/L, ( 103.16 ±28.89 ) ng/L, were higher than the TOS group ( 97.84 ± 25.37)mg/L,(119.17 ±31.77)mg/L,(130.81 ±33.29)mg/L,(76.83 ±21.97)ng/L,(121.15 ±32.64)ng/L, (122.08 ±30.74)ng/L,the difference was statistically significant (t=70.12,58.33,69.17,64.34,79.58,92.17,all P<0.05).Conclusion VATS lobectomy for non-small cell lung cancer has better effects and safety .

Objective To observe the changes of sodium iodide symporter (NIS) in mammary gland of rats at different lactation periods,and to explore iodine uptake mechanism.Methods Seventy-five adult Wistar rats were selected,including 60 females,15 males,weighting 220-250 g.All female Wistar rats were divided into 4 groups according to their body mass via random number table method:normal non-pregnant group,lactating for 7-,14-and 21-day groups,15 rats in each group.All rats were fed with adequate conventional fodder and tap water.In addition to normal non-pregnant group,other three groups of female and male rats were mated at 3 ∶ 1,respectively,then after lactating for 7th,14th and 21th days,mammary gland tissues were harvested.The expressions of NIS mRNA and protein were measured with real time quantitative PCR (qRT-PCR) and immunohistochemical staining,respectively.Results NIS protein was expressed in the small ductal epithelium of mammary gland and the basal lateral membrane under light microscope,obvious brown particles visible.The expression of NIS mRNA (0.79 ± 0.11,1.05 ± 0.21,0.98 ± 0.18,0.89 ± 0.16) in mammary gland showed significant differences between groups (F =5.965,P ＜ 0.05),the expressions of NIS mRNA in 7th and 14th day groups were higher than that of normal non-pregnant group (P ＜ 0.05).The expression of NIS protein in mammary gland showed significant differences between groups (H =32.747,P ＜ 0.05),the staining intensity of mammary gland tissue after lactating for 7th,14th and 21th days groups was stronger than that of normal non-pregnant rats (P ＜ 0.05).Conclusions NIS is expressed in mammary gland of rats at different lactation periods.The iodine uptake of mammary gland is enhanced in early lactation period.

Objective:It aims at constructing the equipment visualization management system in orthopedics on the basis of Godot engine,as well as exploring and discussing its values related to equipment visualization management system in orthopedics of hospitals.Methods:The equipment visualization management system in orthopedics on the basis of Godot engine was designed which further contained data collection,model drawing and function development,then,it further realized the equipment visualization management in orthopedics by relying on the movable terminal.180 medical equipment commonly used in orthopaedic clinic of Beijing Puren Hospital were selected in 2021-2022.Moreover,they were managed by two modes of management which were respectively the traditional equipment management mode(traditional equipment mode)and equipment visualization management system in orthopedics on the basis of Godot engine(visual system).Finally,the effectiveness of the two management modes of the medical equipment,the level of management and the satisfaction scores of doctors,nurses and patients on the two management modes were assessed accordingly.Results:The time utilization rate,quality stability rate and diagnosis and treatment effectiveness rate of the visual system equipment were respectively(95.37±4.06),(96.74±4.72)and(96.41±5.01)%,which were higher than that of the traditional equipment model and the differences were all statistically significant(t=9.608,9.438,4.909,P<0.05).the standardized placement rate,standardized recording rate and intact rate of the visual system equipment were respectively 97.22%(175/180),97.78%(176/180)and 99.44%(179/180),which were higher than that of the traditional equipment model and the differences were all statistically significant(x2=6.972,11.429,9.656,5.236,P<0.05).the failure rate of the visual system was 5.00%(9/180),which was lower than the traditional equipment mode(x2=5.236,P<0.05).the satisfaction scores of doctors,nurses and patients for the visual system equipment were respectively(95.63±3.47),(96.85±3.21)and(95.79±3.92),which were higher than that of the traditional equipment mode and the difference was statistically significant(t=14.068,17.996,14.438,P<0.05).Conclusion:The application of equipment visualization management system in orthopedics on the basis of Godot engine can visualize and manage medical equipment in orthopedics of hospitals,enhance the equipment effectiveness,intensify the equipment management level,as well as improve the users'satisfaction degree with the equipment.
