The sanitary habitation and office are very important for human health, so cleaning is an absolutely necessary part in our living. Although cleaning presents a substantial perceived benefits for our living, there are still some risks for our health. Except for the exposures to dust and other particulate matter suspended during cleaning activities, the main health problem caused by cleaning is the cleaning products. The main hazard composition of cleaning products, air pollution, inhalation pathways, health adverse effects and the measures for reducing the exposures to indoor air pollution caused by cleaning were reviewed in this paper.

Objective To investigate the effect of Tegafur, Gimeracil and Oteracil Potassium Capsules ( TS-1 ) on peripheral blood tissue polypeptide antigen (TPS), soluble MHC class I chain-related molecules A (sMICA), hypoxia-inducible factor-1 (HIF-1α) and human epidermal growth factor receptor 2 ( Her-2 ) in the treatment of patients with advanced cervical cancer.Methods 80 cases with advanced cervical cancer were selected and divided into two groups, 40 cases in the control group were treated with routine clinical therapy, 40 cases in the experimental group were treated with TS-1.Tumor markers, TPS,sMICA,HIF-1αand Her-2 were compared before and after the treatment.Results Compared with the control group, the levels of tumor antigen TA-4,carcinoembryonic antigen (CEA) and squamous cell carcinoma antigen (SCCA) in the experimental group were lower (P<0.05); the TPS, HIF-1, sMICA and Her-2 were lower (P<0.05), and the total effective rate in the treatment group was higher (P<0.05).Conclusion TS-1 has a obvious clinical efficacy in the treatment of advanced cervical cancer.It is speculated that the possible mechanism may reduce the serum tumor marker levels via reducing the TPS and SMICA, HIF-1 alpha, HER-2 levels.

Objective To study the inhibit efficiency of lake sediment phosphorus release by adding chemical reagents and to provide the technical basis for the comprehensive management of city lake.Methods In May 20,2008,Mochou Lake upper sediment and water samples were collected.The phosphorus forms of sediments,total phosphorus(TP),NaOH-P,HCl-P,inorganic phosphorus(IP),organic phosphorus(OP) were analyzed and the pH value and content of TP in water samples were determined.Each water(250 ml)-sediment(10 g) system was respectively added by 0-1 000.0 mg/L of Ca(OH)2,2.0-10.0 mg/L of A12(S04)3 and 0-25.0 mg/L of FeCl3.The pH value and content of TP in water were determined,then the control rate of TP release were calculated.Results The pH values were between 7.6-8.0,TP content was 2.0 mg/L in water of Mochou Lake.The contents of TP,HCl-P,NaOH-P,IP,OP were 2 187.06,1 383.89,526.48,1 910.37 and 276.69 mg/kg respectively.With the increase of Ca(OH)2 concentration,pH value of water increased rapidly,content of TP showed a decreasing trend,control rate of TP release was increased.With the increase of A12(SO4)3 or FeCl3 concentration,pH value of water declined slightly,content of TP showed a decreasing trend,control rate of TP release was increased.Conclusion Ca(OH)2,A12(SO4)3,FeCl3 can significantly inhibit the phosphorus release of sediments in Mochou Lake.

OBJECTIVESTo explore the significance of noninvasive central blood pressure detection in blood pressure management and vessel function assessment of hypertension.

METHODSA total of 348 subjects were recruited in the study and A-pulse CASP software were derived to measure the parameters of CASP and vessel function. The recruited subjects were divided into different groups for analysis according to age and disease.

RESULTS(1) CASP in hypertension group were both higher than those in normal group, while RAI and PRT lower. (2) Hypertensive patients of which brachial blood pressure were controlled have lower CASP and RAI than those above the level. (3) Hypertensive patients whose brachial blood pressure were controlled have significantly higher CASP than normal subjects.

CONCLUSIONSCentral blood pressure is more reflective of actural blood pressure and vessel function. Enhanced control of CASP in hypertensive patients contributes to improving vessel compliance.

Objective:To investigate the effects of ultrasound-guided intervention with methotrexate combined with lauromacrogol on uterine wall thickness and menstrual recovery time in patients with uterine scar pregnancy.Methods:Sixty patients with uterine scar pregnancy who received treatment in Jinhua Wenrong Hospital, Jinhua Central Hospital, and Yiwu Maternity and Children Hospital from February 2019 to February 2020 were included in this study. They were randomly assigned to receive either uterine artery embolization treatment ( n = 30, control group) or ultrasound-guided interventions with methotrexate combined with lauromacrogol ( n = 30, study group). The success rate of treatment, uterine wall thickness at the scar, menstrual recovery time, hospitalization time, hospitalization expenses, incidence of adverse reactions, serum levels of beta-human chorionic gonadotropin (β-HCG) and high sensitivity C-reactive protein (hs-CRP) after 7 days of treatment and uterine wall thickness before and after treatment were compared between the study and control groups. Results:After treatment, the success rate of treatment in the study group was significantly higher than that in the control group [96.67% (29/30) vs. 70.00% (21/30), χ 2 = 7.680, P < 0.05]. Before treatment, there were no significant differences in β-HCG and hs-CRP levels between the control and study groups ( t = -0.197, 0.197, both P > 0.05). After treatment, serum level of β-HCG in the control and study groups was significantly decreased ( t = 22.803, 10.233, both P < 0.01), and serum level of hs-CRP in the control and study groups was significantly increased ( t = -16.357, 7.854, both P < 0.001) compared with before treatment. After treatment, there were no significant differences in serum β-HCG and hs-CRP levels between the control and study groups ( t = 20.413, -20.306, both P < 0.05). After treatment, the incidence of adverse reactions in the study group was significantly lower than that in the control group [6.67% (2/30) vs. 30.00% (9/30), χ 2 = 5.455, P < 0.05). After treatment, menstrual recovery time, hospitalization time and hospitalization expenses in the study group were shorter or less than those in the control group ( t = 5.080, 5.398, 7.599, all P < 0.05). There was no significant difference in the thickness of uterine wall at the scar site between the two groups ( t = -1.045, P > 0.05). Conclusion:Ultrasound-guided intervention with methotrexate combined with lauromacrogol for treatment of uterine scar pregnancy can effectively increase the success rate of treatment, promote the restoration of menstruation, shorten the length of hospital stay, and is highly safe.
