OBJECTIVE:To investigate the clinical efficacy and safety of Cinobufacin capsules combined with radiotherapy in the treatment of median and advanced nasopharyngeal carcinoma. METHODS:Ninety-five patients with median and advanced naso-pharyngeal carcinoma in cancer center of our hospital during 2011-2012 were analyzed retrospectively,and then divided into con-trol group (57 cases) and observation group (38 cases) according to therapy plan. Control group received radiotherapy alone, while observation group was additionally given Cinobufacin capsule 0.5 g,tid,till the end of radiotherapy. A treatment course last-ed for 4 weeks. The prolonged radiotherapy were compared between 2 groups. Clinical response rate was observed in 2 group,and 1-year and 3-year survival rate and the occurrence of ADR were followed up. RESULTS:The proportion of prolonged radiotherapy was 89.47% in control group,which was significantly higher than 52.63% of observation group,with statistical significance(P<0.05). At the end of therapy and one month after therapy,clinical total response rates of observation group were 81.58% and 63.16%,which were significantly higher than 70.18% and 45.61% of control group,with statistical significance (P<0.05). The incidence of white blood cell lowering,hemoglobin lowering,local side effect of radiotherapy, nasopharyngeal dysphagia/odyno-phagia in observation group were significantly lower than in control group,with statistical significance (P<0.05). There was no statistical significance in survival rate between 2 groups in 1st-year and 3rd-year follow-up (P>0.05). CONCLUSIONS:Cinobu-facin capsule combined with radiotherapy can significantly relieve the side effects of radiotherapy in median and advanced nasopha-ryngeal carcinoma patients.

Objective To investigate the relationship of plasma fibrinogen (FIB) and non-highdensity lipoprotein cholesterol (non-HDL-C) with diabetic nephropathy in the elderly with type 2 diabetes. Methods Totally 152 patients (aged 60 years and over) with type 2 diabetics were divided into normal albuminuria (UAER＜30 mg/24 h,n=89) and abnormal albuminuria (UAER≥ 30 mg/24 h,n=63) groups,with high FIB (＞4.00 g/L,n=88) and normal FTB (2.00-4.00 g/L,n=64)sub-groups.The body mass index (BMI),systolic blood pressure (SBP),diastolic blood pressure (DBP),fasting plasma glucose (FPG),postprandial blood glucose (2 hPG),glycated hemoglobin (HbAlc),serum triglyceride (TG),total cholesterol (TC),high density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C),FIB and 24-hour urinary albumin excretion rate (UAER) were measured.The non-HDL-C and estimated glomerular filtration rate (eGFR) were calculated. Results Compared with normal albuminuria group,the values of age,hypertension rate,SBP,Scr and FIB in abnormal albuminuria group were increased [(74.6 ± 7.3) years,57 cases (90.5％),(146.8±23.2)mm Hg,(1.010.7)μmol/L,(4.8±1.5)g/Lvs.(71.6±7.2)years,59 cases (66.3％),(137.7±19.2) mm Hg,(0.8±0.3)μmol/L,(4.2±1.3)g/L,t=-2.536,-2.656,- 2.474,-2.857,x2 =11.936,all P＜0.05] while eGFR was significantly decreased [(68.5±31.2)ml · min-1 · 1.73 m-2 vs.(81.4±25.9)ml · min-1 · 1.73m-2,t=2.791,P＜0.05].The number of patients with high FIB was enhanced in abnormal albuminuria group than normal albuminuria group[45 cases (71.4％) vs. 18 cases (28.6％),x2 =8.085,P=0.004]. The proportion of abnormal albuminuria in high FIB group was lower than that in normal FIB group [(62.6±30.5) ml· min-1 · 1.73 m-2 vs.(83.2±28.7) ml· min-1 · 1.73 m 2,t=2.459,P=0.017].The Pearson analysis revealed that UAER was positively correlated with FIB,TG,TC and non-HDL-C (r=0.276,0.268,0.243,0.176,all P＜0.05).Stepwise regressive analysis showed that FIB was an independent risk factors of urinary albumin in the elderly with type 2 diabetes.Conclusions Higher levels of FIB and non-HDL-C are well correlated with diabetic nephropathy in the elderly with type 2 diabetes.

Objective To evaluate the expression of transient receptor potential melastatin 7(TRPM7)in cholangiocarcinoma and its correlation with prognosis.Methods The expressions of TRPM7 were detected by SP immunohistochemical in 49 cases of cholangiocarcinoma,7 cases of benign bile duct lesions and 36 cases of adjacent histologically noncancerous bile duct tissues,and to analysis its relationship with the clinical pathological characteristics of cholangiocarcinoma.Results The positive expression rate of TRPM7 in cholangiocarcinoma was 77.6%(38/49),which was higher than that in benign bile duct lesions(0,0/7)and adjacent his-tologically noncancerous bile duct tissues(2.8%,1/36),the difference was statistically significant(P <0.05).The positive expres-sion of TRPM7 in cholangiocarcinoma was correlated with the TNM stage of tumor,lymph node metastasis and organ metastasis (P <0.05),but not related to patients′age,gender,site,differentiation and hepatitis(P >0.05).Kaplan-Meier analysis showed that increased expression of TRPM7 was associated with shorted overall survival (P <0.05).Cox regression analysis showed that the expression level of TRPM7 was significantly associated with prognosis and an independent risk factor for prognosis(P <0.05 ). Conclusion TRPM7 plays an important role in the tumorigenesis progression,invasion,and metastasis of cholangiocarcinoma,and is an important factor for prognosis in patients with cholangiocarcinoma.

ObjectiveTo study the relationship between the exposure to two kinds of phthalate esters （PAEs） ［Di-N-butyl phthalate，（DBP） and Di-（2-ethylhexyl）phthalate （DEHP）］ and estrogen homeostasis in pregnant women. MethodsIn 2021， we classified the Jiading District of Shanghai into five geographical areas， east， west， south， north and central. A total of 151 pregnant women from each area were selected for questionnaire survey， with random urine samples during first， second， and third trimesters collected. A DBP metabolite ［Mono-N-butyl phthalate （MBP）］ and two DEHP metabolites ［Mono（2-ethylhexyl） phthalate （MEHP）， Mono（2-ethyl5-oxohexyl） phthalate， （MEOHP）］ and three estrogens ［estrone （E₁）， 17β -estradiol （E₂）， and estriol （E₃）］ in urine were determined by ultra-performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry. After a natural logarithmic transformation of PAEs metabolite levels and estrogen concentration， multivariable linear regression was used to control potential confounders and determine the relationship between PAEs metabolite levels and estrogen concentration. ResultsThe detection rates of three PAEs metabolites in urine of pregnant women were more than 98%. The median corrected concentrations of MBP， MEHP and MEOHP were 5.18， 0.59 and 4.23 mg·kg^-1， respectively. During the whole pregnancy， MEOHP was positively correlated with E₁ （β=0.450， 95%CI： 0.057‒0.844）， and MBP was positively correlated with E₃ （β=0.250， 95%CI： 0.034‒0.465）. Stratified by trimesters， MBP was positively correlated with E₃ in the first trimester （β=0.428， 95%CI： 0.103‒0.752）. MEOHP was positively correlated with E₁ in the second trimester （β=0.734， 95%CI： 0.130‒0.752）， and had a possitive trend with E₁ in the third trimester （β=0.744， 95%CI： -0.140‒1.629）. In addition， MEHP had a negative correlation with E₁ in the second trimester （β=-0.498， 95%CI： -1.063‒0.066）. MEOHP had a positive correlation trend with E₂ （β=0.628， 95%CI： -0.101‒1.356） in the third trimester. ConclusionPAEs exposure may interfere with estrogen homeostasis during pregnancy and differs by trimesters. Given the cross-sectional nature of this study， it warrants further study to validate the findings.
