APC model analysis of lung cancer death trend in residents of Macheng City, Hubei Province, 1984-2018 / 公共卫生与预防医学

Objective To study the trends of lung cancer mortality among adult residents in Macheng City, Hubei Province from 1984 to 2018． Methods Mortality data was extracted from Macheng City disease surveillance points (DSPs) system and China Demographic Yearbook. The age-period-cohort (APC) model and Intrinsic Estimator algorithm were used to estimate the age effect, period effect and cohort effect of lung cancer mortality. Results The age effect coefficient of lung cancer mortality increased with age from 20 to 74 years old. The mortality risk of the 70-74 group was 42.62 times that of the 20-24 group. The period effect coefficient of lung cancer mortality also continued to rise with time. The cohort effect coefficient was parabolic, and residents born in 1939-1943 had the highest coefficient (1.298 4). Conclusion The risk of lung cancer death of adult residents in Macheng City significantly increased with the year and the rapid development of socio-economics.

Television Viewing Time and Breast Cancer Incidence for Japanese Premenopausal and Postmenopausal Women: The JACC Study / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: The evidence on effects of TV viewing time among premenopausal and postmenopausal women for breast cancer risk remains controversial and limited. MATERIALS AND METHODS: A prospective study encompassing 33,276 (17,568 premenopausal, and 15,708 postmenopausal) women aged 40-79 years in whom TV viewing time, menstrual, and reproductive histories were determined by a self-administered questionnaire. The follow-up was from 1988 to 2009 and hazard ratios (HRs) with 95% confidence intervals (CIs) of breast cancer incidence were calculated for longer TV viewing time in reference to shorter TV viewing time by Cox proportional hazard models. RESULTS: During 16.8-year median follow-up, we found positive associations between TV viewing time and breast cancer incidence with a borderline significant trend among total women and a significant trend among postmenopausal women. Among total women, the multivariable HRs (95% CIs) for risk of breast cancer in reference to < 1.5 hr/day of TV viewing time were 0.89 (0.59-1.34) for 1.5 to < 3.0 hr/day, 1.19 (0.82-1.74) for 3.0 to < 4.5 hr/day, and 1.45 (0.91-2.32) for ≥ 4.5 hr/day (p for trend=0.053) and among postmenopausal women, the corresponding risk estimates were 1.10 (0.42-2.88), 2.54 (1.11-5.80), and 2.37 (0.92-6.10) (p for trend=0.009), respectively. CONCLUSION: Prolonged TV viewing time was associated with increased risk of breast cancer, especially among postmenopausal women.

Prospective efficacy of chronic sinusitis lost to short-term follow up after nasal endoscopic surgery / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the prospective efficacy of chronic sinusitis lost to short-term follow up after nasal endoscopic surgery and the influential factors.@*METHOD@#Prospective efficacy of 153 chronic sinusitis (CRS) was evaluated . All cases were treated by nasal endoscopic surgery at least 1 year ago but lost to follow up within 3 months after surgery. The clinical data of 153 patients were analyzed, including gender, age, educational level, course of the disease, smoking and drinking history, early surgery history, allergic rhinitis (AR) history, nasal polyps, visual analogue scale (VAS) score, nasal endoscopy score, CT examination score, the endoscopic experience of surgeons, medication of intranasal glucocorticoid and nasal irrigation after surgery. Multifactor logistic regression analysis were used to analyze the data.@*RESULT@#Among 153 patient, the symptoms of 32 cases (20.9%) were completely control, while those of 74 cases (48.4% ) were partially control, and the symptoms of 47 cases (30.7%) were not controlled. The curative effect were better for CRS without nasal polyps, AR or early surgery history, with CT examination score < or = 5, operated by surgeons with experience of endoscopy surgery for more than 5 years. and treated with intranasal glucocorticoid for more than -1 weeks after surgery.@*CONCLUSION@#Postsurgery follow-up should be paid more attention to in treatment of CRS. Plans of follow up should be adjusted to patients condition. Treatment of postoperative sinus cavity should be minimized when the lesion is slight and operated properly.

Clinical analysis of 337 cases of chronic rhinosinusitis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the clinical symptoms and signs situation of chronic rhinosinusitis, for future treatment provides the basis.@*METHOD@#The clinical data of 337 patients with chronic sinusitis were analyzed, using SPSS 18.0 software and conducted Person chi-square test and Kruskal-Wallis test to analysis.@*RESULTS@#VAS total score of chronic nasal sinusitis patients is 15.9 +/- 5.7. The three top of severe symptoms were: stuffy nose 56 cases (16.6%), nasal secretions or postnasal drip 23 cases (6.8%) and dizziness or headache 11 cases (3.3%), there are statistically significant differences (chi2 = 430.923, P 0.05).@*CONCLUSION@#Comprehensive treatment should be proceeded according to different symptom severity and sinus lesions parts with patients, grasped the surgery procedures strictly, so as to improve the cure rate.

Determination of Emodin and Chrysophanol in Rhubarb Sodium Bicarbonate Table by HPLC / 浙江中医药大学学报

[Objective] TO establish an HPLC method for the determination of emodin and chrysophanol in rhubarb sodium bicarbonate tablets.[Methods] An HPLC method was applied;Chromatographic column was Shim-pack clc-ODS(150?6.0mm,5.0um);The mobile phase was methanol-0.1% phosphoric acid (85:15);Velocity of flow was 1.0ml/min;The detaction wavelength was 254nm.[Resulet] The linearty of this method was well.Emodin and chrysophanol average recovery rates were 98.5%,99.3%;RSD=2.75%,2.83%(n=9).[Conclusion] This method is simple,accurate with strong reproducibility,and can be used for the quality control of rhubarb sodium bicarbonate tablets.

Clinical significance of NMP 22 in early diagnosis of bladder cancer / 中华泌尿外科杂志

10 U/ml was determined as positive value.Urinary NMP 22 protein was elevated in 22 cases.Bladder cancer was diagnosed in 11 cases.The sensitivity and specificity of the NMP 22 test were 100%(11/11) and 81%(46/57),respectively.Cystoscopy alone identified 35% of the cancers (4/11).Among 22 cases with elevated NMP 22,1 case was dignosized as bladder cancer during 1 year visit. Conclusions Urine NMP 22 is a new useful marker in early diagnosis of bladder cancer.
