ABSTRACT
Objective To analyze the clinical characteristics and changes of serum tumor markers in lung cancer patients with different smoking status in Hanzhong area. Methods A retrospective analysis was performed on 642 hospitalized lung cancer patients in Hanzhong area from March 2017 to March 2019. According to their smoking status, they were divided into observation group (smoking history, n=404) and control group (no smoking history, n=238). Age, sex, place of residence, basic information of the disease including pathological stage, pathological type, short-term efficacy, survival and serum tumor marker level were analyzed retrospectively. Results The proportion of male in observation group (67.08%) was significantly higher(57.56%) (χ2=5.855,P2=4.824 , P2=2.110 , P2=15.291, P 2=10.817,P2=2.051, P>0.05). The 1-year survival rate of the observation group (64.85%) was significantly lower than that of the control group (73.95%) (χ2=5.255, P<0.05). Conclusion Middle-aged and elderly male smokers in Hanzhong area have a high incidence of lung cancer, multiple stage Ⅲ squamous cell carcinoma, and the level of tumor markers in serum is higher than that of non-smokers. The prognosis is not good, so we should encourage patients to quit smoking, which can improve the survival rate of patients.
ABSTRACT
Objective To establish the reference range of thyroid function from the normal pregnant women in different pregnant period in Hanzhong region.Methods According to the NACB inclusion criteria,collected local resident pregnant women 4 031 cases,from July 2012 to December 2015.With the combination of random sampling,stratified sampling and cluster sampling,thyroid hormone levels were measured by a fully automated chemiluminescence analyzer and its accompanying reagents.All patients were divided into three groups:998 cases in early pregnancy (T1),1 543 cases in mid-pregnancy (T2),1 490 cases in late pregnancy (T3),and 105 cases of non-pregnant women in childbearing age (T0) were selected as control group.Results The levels of thyroid hormones were different among three periods of pregnant women.TSH were 0.25～5.32,0.42～6.26 and 0.61～7.68 mIU/L respectively in the early,middle and late stages.FT3 were 3.54～6.04,3.57～5.94 and 2.93～5.40 pmol/L,respectively.FT4 was 7.11～16.88,6.78～16.94 and 6.03～16.87 pmol/L.Thyroid hormone levels in pregnant women compared with non-pregnant women,there were significant differences (TSH:x2=233.183,P＜0.05,FT4:x2 =388.12,P＜0.05 and FT3:x2 =558.795,P＜0.05).TSH were lower in early pregnant women comparing to non-pregnancy women,and higher in middle-late pregnant women.The change of FT3 and FT4 were consistent,and reduced with the extension of pregnancy comparing to non-pregnancy women.Conclusion The level of thyroid function in pregnant women were different from non-pregnant women.and the normal reference range of local pregnant specific thyroid hormone should be established.
