Objective To explore a new method for lacrimal passage irrigation after laser dacryocystoplasty surgery. Method One-hundred patients (104 eyes), which underwent laser dacryocystoplasty surgery combined with lacrimal drainage tube indwelling, were divided into two groups. In Group A (50 patients, 52 eyes), lacrimal passage irrigation was performed by traditional No.5 needle. While in Group B (50 patients, 52 eyes), it was done by No.7 blunt round needle designed by the researchers. Lacrimal passage irrigation was performed three times, each at the 3rd day, 1 week and 1 month after surgery. The silicone tube was removed 3 months after surgery and the treatment was evaluated. Results The total effective rate was 64% (32/50) in Group A and 92%(46/50) in Group B. The difference was statistically significant (χ2=18.537, P < 0.01). Conclusions The No.7 blunt round needle showed better effect when used for lacrimal passage irrigation after laser dacryocystoplasty surgery. It could improve the efficiency of lacrimal passage irrigation, thus decreasing irrigation times and reducing psychological pressure for the patients, which is worthy of clinical application.

Objective To describe the trend of lung cancer mortality in Xuanwei City,Yunnan Province,from 1990 to 2016 and provide scientific evidence for the prevention and control of lung cancer in Xuanwei.Methods Mortality data from the 2nd(year 1990-1992)and 3rd(year 2004-2005)Retrospective Survey on Causes of Death,and the Routine Death Registration System(year 2011-2013 and 2014-2016)in Xuanwei were used in this study.We calibrated the missing report of the mortality data for the corresponding periods,calculated the crude mortality rates,standardized mortality rates and corresponding 95% of different types of lung cancers in the above four periods.Results The crude mortality rates of all lung cancers in Xuanwei for these four periods(1990-1992,2004-2005,2011-2013,and 2014-2016)were 34.0/100 000,89.8/100 000,102.3/100 000 and 87.2/100 000 respectively.The standardized morality rate of lung cancer remain high in Xuanwei although it has been decreasing since 2004.Morality rates of lung cancer for most age groups showed decreasing trends.The decrease has been statistically significant in the ≤ 40 year group since 2014.Except for Longchang,the standardized mortality rates have decreased in all other townships with high lung cancer prevalence.Conclusions Although the mortality rate of lung cancer remains high in Xuanwei,it has shown a decreasing trend since 2004.The decrease in lung cancer mortality in populations younger than 40 years is statistically significant.

Objective To investigate the effect of recombinant human growth hormone (rhGH) on the growth rate, glucose and lipid metabolism and bone metabolism in children with idiopathic short stature (ISS). Methods The clinical data of 150 children with ISS admitted to the hospital from January 2010 to January 2015 were collected. The children were divided into the routine group (68 patients) and rhGH group (82 patients) according to the treatment methods. The routine group was given enhanced nutritional guidance, enhanced protein and calcium intake, and guidance for exercise. On this basis, rhGH group was additionally treated with rhGH. The intervention lasted for 12 months, and changes of height, weight, bone age (BA) and growth velocity (GV) in two groups were statistically analyzed. Changes in fasting blood glucose (FBG), insulin (INS), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and other glucose and lipid metabolism indicators before and after treatment were detected. The insulin sensitivity index (ISI) was calculated, and changes in serum insulin-like factor 1 (IGF-1), osteocalcin (OC), bone alkaline phosphatase (BAP), typeⅠprocollagen amino-terminal propeptide (PINP), β-collagen degradation products (β-CTX) and other bone metabolism parameters before and after treatment were determined. The incidence of adverse reactions in both groups was statistically analyzed. Results There were no significant differences in height, weight, BA or GV between two groups before treatment (P>0.05). After 12 months of treatment, the above indicators in both groups were increased (P<0.05). The height, weight, BA and GV were (132.12 ± 7.26) cm, (26.21 ± 1.74) kg, (9.41 ± 0.37) years old and (10.03 ± 2.41) cm/year of the rhGH group, which were significantly higher than those of the routine group [(124.22 ± 6.31) cm, (24.13 ± 1.92) kg, (8.96 ± 0.42) years old and (5.85 ± 1.76) cm/year (P<0.05)]. There were no significant differences in glucose and lipid metabolism levels between two groups before and after treatment (P>0.05). There was no statistical difference in bone metabolism indexes between two groups before treatment (P>0.05). After 12 months of treatment, PINP, IGF-1, OC and BAP in both groups increased while β-CTX decreased (P<0.05). PINP, IGF-1, OC and BAP in rhGH group [(598.21 ± 78.57) μg/L, (301.23 ± 51.45) μg/L, (78.52 ± 12.65) μg/L, (171.26 ± 42.17) U/L] were higher than those in routine group [(520.14 ± 47.55)μg/L, (244.35 ± 46.38)μg/L, (70.25 ± 9.77) μg/L, (120.55 ± 38.42) U/L] (P<0.05), whileβ-CTX was lower than that in routine group [(0.48 ± 0.26)μg/L vs (0.63 ± 0.24) μg/L] (P<0.05). There were no significant difference in adverse reaction between two groups [3.66％(3/82) vs. 0, P>0.05]. Conclusions The rhGH treatment of children with ISS can obviously promote the growth and improve bone metabolism and growth rate of children, without significant adverse effect on their glucose and lipid metabolism and with certain safety.

Objective: This study aims to explore the effect of practice on the triage and acuity scale in the emergency department of Stomatological Hospital. Methods : 150 emergency patients admitted to the emergency department from April 2016 to July 2016 were randomly selected as the control group before the implementation of graded district diagnosis and treatment, and 150 emergency patients admitted from August 2016 to November 2016 were selected as the observation group after the implementation of graded diagnosis and treatment. The control group was treated with the traditional nursing treatment mode, and the observation group adopted the triage and acuity scale mode. The efficiency of treatment for the patients and the degree of satisfaction of the patients in terms of the nursing work was compared between the two groups (waiting time, checkup time, start treatment time). Results: A comparison of the patients in the observation group and control group showed that the waiting time (min)(25.63 ± 8.75 vs. 35.57 ± 10.60, t = -8.52, P < 0.001), the time of accepting examination (min)(24.80 ± 7.90 vs. 39.23 ± 12.42, t = -12.01, P < 0.001) and the starting time of treatment （min）(28.67 ± 9.37 vs. 40.47 ± 10.86, t = -10.08, P < 0.001) were significantly lower in the observation group than the control group (P < 0.05). The degree of satisfaction with the nursing work for the patients in the observation group (96.67%) was higher than that of the control group (85.33%), and this difference was statistically significant (χ2=17.647, P=0.001). Conclusion The application of a triage and acuity scale in the diagnosis and treatment of stomatological emergency patients according to the severity and urgency of disease can ensure the priority of treatment in critically ill patients, the safe and efficient performance of emergency work, and improvements to the efficiency and quality of emergency medical services.

OBJECTIVE To evaluate the consistency between the quetiapine LC-MS/MS kit and the laboratory-built method(reference method) in the detection results of quetiapine therapeutic drug monitoring. METHODS A total of 120 remaining plasma samples were collected from patients receiving quetiapine therapeutic drug monitoring from March to October in 2021. The plasma concentration of quetiapine was detected by kit and reference method respectively. The analysis of correlations and consistency was performed by outlier analysis, linear regression and Bland-Altman method. RESULTS No outliers were detected. The linear regression equation was Y=1.018X+4.400(r=0.998), indicating a good correlation. The Bland-Altman plot analysis showed good agreement between the two measurements. CONCLUSION The detection results of quetiapine LC-MS/MS kit and reference method are in good agreement. The kit can be used for clinical quetiapine treatment drug monitoring.
