Objective To investigate the therapeutic effect of arterial interventional chemotherapy on bulky cervical cancer. Methods One hundred and twenty-six patients with bulky cervical cancer were randomly divided into two groups. Arterial interventional chemotherapy group(n =74, C gronp), and radiotherapy group(n =52 R group). Patients in C group underwent internal iliac arterial infusion chemotherapy by using Seldinger technique. The chemotherapy regimens of cervical squamous cell carcinoma were prescribed including cisplatin and BLM, and cervical adenocarcinoma were prescribed including cisplatin and ADM and VCR. Patients in R group were only given radiotherapy Ir192 high-dose rate intracavitary radiotherapy was performed with A point dose at 24 Gy. Both groups of patients were followed up after two weeks. Results The tumor regression rate of C group was 93.24 %, significantly higher than 71.15 % in R group(P 0.05). The 3-year recurrence rate between the two groups had obvious difference(P 0.05). Conclusion Neoadjuvant chemotherapy can effectively reduce tumor volume, and postoperative 3-year recurrence rate, increases surgery rate on bulky cervical cancer. But the effect on long-term survival rate needs to be evaluated further through long-term follow-up.

Objective To investigate the effect of psychological intervention on alleviation of negative emotion of patients with cervical cancer.Methods 100 patients diagnosed with cervical cancer and needed surgery were randomly divided into the control group and the observation group with 50 in each.The control group was given routine preoperative interview,the observation group received health education,cognitive therapy,psychological intervention.Self-rating anxiety scale (SAS) and serf-rating depression scale (SDS)were used to evaluate the degree of negative emotion.Results SDS and SAS score of the obscrvation group were significantly lower than the control group,incidence of negative emotion was significantly lower than the control group.Conclusions Application of comprehensive psychological intervention for patients with cervical cancer can reduce negative emotion such as anxiety and depression,help patients cope with treatment,increase tolerance to surgery,improve the effect of surgical treatment,and promote an early re-covery of patients.

Objective To analyse the efficacy of hysteroscopic resection and norethisterone in abnormal uterine bleeding.Methods 38 cases of submucos myoma of uterine body,26 cases of endometrium polyps and 16 cases of complex hyperplasis of endometrium were treated with hysteroscopic resection,and all the cases take norethisterone for one month before hysteroscopic resection and go on taking norethisterone for three months after operation.All the cases were followed up with the improvement of symptoms and the chang of uterine cavity.Results All the cases were followed up for 3～18 months after operation.The efficacy of submucous myoma of uterine body was 92.10%(36/38) and that of endometrium polyps was 84.61%(22/26) and that of complex hyperplasis of endometrium was 93.75%(15/16).Conclusion The treatment of hysteroscopic resection and norethisterone in submucous myoma,endometrium polyps and complex hyperplasis has advantages of satisfied results,slight trauma,fast recovery and fewer recurrence relapse.

Objective To summarize the analytical results of radioactivity in the food and drinking water nationwide following the Fukushima nuclear accident,and to evaluate its possible contamination to the public health in China.Methods According to the national standard methods and IAEA,FDA correlative references,the scheme was established on sampling and measurements in food and drinking water after the breakout of the accident.The quality control was requested on the sampling,analyses and data report.Results Trace artificial radioactive isotope of 131I was measured in spinach samples on 2 April 2011 in Beijing. Subsequently 131I was found in 10 kinds of growing leaves vegetables (open field)nationwide.The maximum detectable activity of 131I in vegetables was about 3.1 Bq/kg.Since 3 May 2011,the concentration of 131I has been below the detection limits.No artificial radionulide was detectable in all of milk,drinking water and marine products samples during March to December,2011.Conclusions The food and drinking water measurements in China following the Fukushima nuclear accident denoted that the minor amounts of 131I in vegetables might result in very low absorbed dose and induce no impact on human health.The maximum detectable activity of 131I in vegetables was close to that reported in European countries,and much less than that measured in China immediately after the Chernobyl accident in 1986.

Objective To investigate the relationship between cardiovascular risk factors and arterial elasticity in elderly hypertensive patients.Methods 253 subjects were divided into two groups:hypertension group (n=141) and non-hypertension group (n =112).Carotid-femoral pulse wave velocity (C-FPWV),carotid-radial PWV (C-RPWV),height and weight were determined.Fasting plasma levels of blood glucose (BG),blood lipids,insulin,endothelins (ET),nitric oxide (NO) and high sensitivity C-reactive protein (hsCRP) were assessed.Results C-FPWV and CRPWV were higher in hypertension group than in non-hypertension group [(11.7±1.9) m/s vs.(9.7±1.1)m/s,(11.7±1.7) m/s vs.(9.4±1.1)m/s,t=8.43 and-6.30,both P＜0.01].Body mass index (BMI),systolic blood pressure (SBP),diastolic blood pressure (DBP),levels of triglyceride (TG),BG,ET,NO and hsCRP,HOMA-IR had significant differences between the two groups (t=-5.27,-4.18,-6.00,6.29,-4.18,-4.86,-3.41,respectively,all P＜0.05).Pearson correlation analysis showed that CFPWV was correlated with SBP,age,DBP,fasting BG,NO,ET,TG,HOMA IR,cholesterol (CHO),hsCRP (r=0.534,0.374,0.340,0.338,-0.306,0.242,0.228,0.225,-0.218,0.178,respectively,all P＜0.05); C-RPWV was correlated with age,DBP,SBP,NO,TG (r=0.312,0.319,0.241,-0.197,0.151,respectively,all P＜0.05).Multiple regression analysis demonstrated that C-FPWV=4.640 + 0.081× HOMA IR+ 0.047× age+0.035×SBP+0.29×TG-0.017×NO+0.014×ET+0.132×hsCRP,r2=0.514; CRPWV=3.161+0.034×age+0.033×DBP+0.313×fastingBG+0.013×ET-0.013×NO,r2=0.390.Conclusions The decreases of arterial elasticity are closely related with endothelial function,insulin resistance,levels of blood lipids and hsCRP in elderly patients with hypertension.
