Objective To evaluate the effects of a health education project on prevention and control of iodine deficiency disorders.Methods From January to June 2011,an investigation was conducted using combined unified questionnaire in 9 counties on target population,and 3 townships were chosen in each project county.Health educational activities were carried out in grade 5 classes in the central primary school.In the meantime,3 villages were chosen in each selected township where the health educational activities in the community were carried out.Before and after the health educational activities,questionnaire surveys on knowledge of iodine deficiency disorders were conducted in each project county.Thirty students in one class of grade 5 in the central primary school were selected,and 15 women of childbearing age near the central primary school were selected too.The health education content included but not limited to:popular science films about the knowledge on endemic disease prevention and public-interest ads were broadcasted by radio,television,newspapers and other media in the project counties,aiming at spreading knowledge on prevention and treatment of endemic diseases.In each of the project township government and village committee locations,posters,banner pieces and slogan suspensions about knowledge on endemic disease prevention were posted or put up.In the project rural hospitals,a special bulletin boards was set up,and in the village clinics (rooms),posters were put up,to carry out a training program for women of childbearing age on endemic disease prevention.In primary schools,students in grades 4 to 6 were given a class about knowledge on prevention and treatment of iodine deficiency disorders,aiming at their transferring the learned knowledge to family members.Results A total of 2678 persons were investigated before and after the health education.After health education,the rate of knowledge(the correct answer rate) on iodine deficiency disorders increased from 69.04％ (1920/2781) to 94.08％ (2622/2787,x2 =580.63,P ＜ 0.05) among primary school students,and 74.76％(924/1236) to 92.60％(1139/1230,x2 =143.59,P ＜ 0.05) among women of childbearing age.Conclusions The rate of knowledge awareness in the students and the women of childbearing is increased significantly after the health educational activities.Systematic and targeted health education activities are effective measures in prevention and control of iodine deficiency disorders.

OBJECTIVETo observe the clinical efficacy difference on vegetative state in children between acupoint injection combined with plum-blossom needle and western medication based on basic treatment.

METHODSForty-eight children of vegetative state were randomized into an observation group and a control group, 24 cases in each one. On the basis of the treatment of transcranial magnetic stimulation apparatus, balancing treatment apparatus and massage, the acupoint injection and tapping method with plum-blossom needle were adopted in the observation group, in which Xingnaojing injection, mouse nerve growth factor (mNGF) injection, monosialotetrahexosylganglioside sodium injection (MSI), compound Danshen injection were divided in 6 pairs and were injected respectively in Baihui (GV 20), Yongquan (KI 1), Fengfu (GV 16), Yamen (GV 15) and the others, 0.5 mL in each acupoint, once a day for continuous 10 days. Additionally, the tapping method with plum-blossom needle was used on the Governor Vessel and Jiaji (EX-B 2) on the back. In the control group, the intravenous infusion was adopted with citicoline sodium injection, mannitol injection and dexamethasone injection. The treatment was given once a day, 20 days of treatment made one session and totally 3 sessions were required in the two groups. The clinical efficacy, the vegetative state score and the mean curing time were observed after 20 days, 40 days and 60 days of treatment between the two groups.

RESULTSThe effective rates were 58.3% (14/24), 70.8% (17/24) and 79.2% (19/24) in 20 days, 40 days and 60 days of treatment in the observation group and 20.8% (5/24), 45.8% (11/24) and 58.3% (14/24) in the control group respectively. The efficacy in the observation group was superior to those in the control group (P < 0.01, P < 0.05). The vegetative state score was improved apparently after 20 days, 40 days and 60 days of treatment as compared with those before treatment separately (all P < 0.05). It was improved obviously at the each time point after treatment in the observation group as compared with that in the control group (3.34 +/- 2.41 vs 2.64 +/- 11.56, 6.20 +/- 1.46 vs 4.34 +/- 1.64, 11.26 +/- 2.63 vs 8.75 +/- 2.18, all P < 0.05). The mean curing time was (45.67 +/- 16.24) days in the observation group, which was shorter apparently than that of (55.34 +/- 4.57) days in the control group (P < 0.05).

CONCLUSIONBased on basic treatment acupoint injection combined with tapping method of plum-blossom needle achieve the reliable efficacy on vegetative state in children.

OBJECTIVE:To discuss the effect of trastuzumab combined with chemotherapy on efficacy and serum tumor mark-ers in patients with human epidermal growth factor receptor 2(HER2)positive advanced gastric cancer. METHODS:74 advanced gastric cancer patients in HER2 positive were randomly divided into observation group and control group,37 cases in each group. Control group received cisplatin + capecitabine chemotherapy;based on it,observation group additionally received trastuzumab by intravenous infusion in the first day,8 mg/kg. 21 d was a course,and it lasted for 6 months. The short-term efficacy,long-term effi-cacy,serum tumor marker contents and toxic and side effects were compared between 2 groups. RESULTS:The effective rate (56.76% vs. 32.44%)and control rate(89.19% vs. 65.86%)in observation group were significantly higher than control group,the differences were statistically significant(P<0.05);progression-free survival time and median survival time in observation group sig-nificantly longer than control group,the differences were statistically significant(P<0.05);contents of serum carcinoembryonic anti-gen,carbohydrate antigen (CA)199,CA724 in observation group significantly lower than control group,the differences were statis-tically significant(P<0.05). And there were no significant differences in the incidences of nausea and vomiting,liver damage,bone marrow suppression and hand-foot syndrome in 2 groups (P>0.05). CONCLUSIONS:Trastuzumab combined with chemotherapy helps to reduce serum tumor markers content,and improve short-term efficacy,long-term efficacy of advanced gastric cancer patients with positive HER2.

Objective To explore the changes of weight,body mass index(MBI),serum glucose,serum insulin in sodium valproate(VPA)-treated children with epilepsy.Methods The study was carried out in 30 epileptic children treated with VPA for 3 months.Weight,height,serum glucose and insulin levels were conducted before and after VPA treatment.Serum insulin levels were detected by radioimmunoassay.Results After 3 months' treatment,body weight [(15.68?3.82)kg vs(19.64?4.75)kg,t=3.56 P0.05].Conclusions VPA therapy can make insuline weight,BMI,serum insulin increased and may lead to insulin resistance.Insulin resistance may be one of the reasons for weight gain in VPA-treated patients.

To explore the effect of estrogen on pathogenesis of osteoporosis in women with maintenance hemodialysis. One hundred and twenty women aged 18-45 years had been undergoing maintenance hemodialysis for ≥ 3 months were included. Of them ,60 women without osteoporosis served as control group and the other 60 women with osteoporosis as observation group. Serum concentrations of estradiol, tumour necrosis factor-α (TNF-α), parathyroid hormone (PTH), and calcium were determined, meanwhile bone mineral density (BMD)was measured by quantitative computed tomography. Serum estradiol levels in the observation group were lower while TNF-α level were higher than those in control group (all P<0. 05). PTH and calcium levels were not significantly different (P= 0.567 and P = 0. 588). In the observation group, linear correlation analysis revealed positive correlation (r = 0. 865 ,P<0. 01)between estradioi and BMD,while multiple linear regression analysis showed that serum estradiol and calcium levels were positively correlated with BMD, and the concentrations of TNF-α and PTH were negatively correlated with BMD (F= 140.32 ,P<0.01). Estradiol levels were found to have greater effect on BMD(t=5. 386, P<0. 01). Lowered serum concentration of estradiol in women with maintenance hemedialysis seems to be a major factor related to osteoporosis,it accelerates the pathogenesis of osteoporosis by modulating TNF-α.
