Objective To study the effect of lead exposure in different development periods (father BBLL and mother BBLL,MPBLL,UCBLL,IBLL,CBLL) on children behavior problems. Methods From 1996 to 2004,a nine-year epidemiological cohort study was conducted in a place with severe environmental lead pollution, Guichi district of Chizhou city in Anhui province, China. 210 newly-married couples with the intention to pregnancy and living around a lead and zinc smelt factory from Dec,1996 to Dec,1998 until delivery and then their offspring were chosen. 161 children were investigated through the questionnaires and Achenbach child behavior checklist(CBCL)at Nov,2001 and Aug,2004. Meanwhile, 210 couples baseline blood (father BBLL and mother BBLL), 93 mid-pregnancy blood(MPBLL), 98 umbilical cord blood (UCBLL),165 blood of infants(IBLL), 161 blood of children (CBLL) were collected to determined the levels of lead by PE-AA800 atomic absorption spectrophotometer. Results Geometric mean of mother BBLL, father BBLL, children BLL, infants BLL, UCBLL and MPBLL were (62.71?2.18)?g/L,(72.93?2.06)?g/L, (91.93?1.58)?g/L, (130.39?1.88)?g/L, (54.32?2.11)?g/L and (50.93?1.95)?g/L respectively,and the proportion of blood lead level at which were higher than 100 ?g/L were 32.38%, 38.10%, 45.34%, 43.03%, 10.20%, 9.68% respectively. In 161 infants, the incidence of abnormal behavior problems was 16.1%. The scores of delinquent and abruption in boys were significant higher than those in girls, while the scores of depression and social withdrawal in girls were higher than those in boys. The single correlative and the multiple stepwise regression analysis showed that the score of abruption was positively correlated significantly with MPBLL(?=0.162,P

Objective To explore preventive effect of evidence-based nursing intervention program in patients at high risk of pressure ulcer in intensive care unit.Methods A total of 227 patients with risk evaluation score of Braden leas than 12 were randomly divided into the observation group (125 cases) and the control group (102 cases).The control group was only given regular nursing interventions.Patients in the observation group received evidence-based nursing interventions : including turning over per 2 hours, turning prostration to 30 degree left to fight inclined position, raising patient's head lower than 30 degree and putting a soft pillow under his/her heels; the patients whose risk evaluation score of Braden was less than 7, with cervical fracture or turning ever was limited by her/his situation needed to use air bed; comfeel transparent paste was used on the surface probably suffered from skin ulcer;, giving PN or EN according to patients' nutritional condition; keepping the skin around anus dryness.The incidence of pressure ulcer be-tween the two groups was compared.Results The incidence rate of pressure ulcer was siguificantly lower in the observation group than that in the control group.The occurring time significantly delayed and the sit-uation significantly better.Conclusions The evidence- based nursing inventions can lower the incidence rate of unavoidable pressure ulcer,reflect the scientific and artistic characteristics of nursing care, also effi-cient allocate limited nursing resources and reduce the incidence of pressure ulcer.

Objective:To evaluate the effect of non-pharmacological interventions on benefit finding of breast cancer patients by using network Meta-analysis.Methods:Randomized controlled trials on the effect of non-pharmacological interventions on the benefit finding of breast cancer patients were retrieved by computer from CNKI, VIP, Wanfang Date, China Biology Medicine disc, PubMed, Web of Science, Cochrane Library, EBSCO, Embase, Medline, Ovid, CINAHL and other databases. The retrieval time was from establishment of the databases to October 15th, 2023. Literature screening and data extraction were carried out independently by two researchers. The Cochrane Manual 5.1.0 randomised Controlled Trial Bias Risk Assessment Scale were used to evaluate the included literature. And the Stata 14.0 were used for Network Meta-analysis.Results:A total of 10 literatures were included. The results of Network Meta-analysis showed that cognitive behavior therapy was the best intervention in improving the benefit finding of breast cancer patients. The effects of different non-pharmacological intervention methods in descending order were cognitive behavior therapy, yoga, acceptance and commitment therapy, self disclosure and muscle stretching.Conclusions:Existing evidence suggests that cognitive behavioral therapy is most effective in improving benefiting finding in breast cancer patients, but more valuable evidence support and high-quality randomized controlled trial studies are needed to further validate.

Objective:To investigate the effect of laparoscopic ovarian cystectomy on anti-Mullerian hormone (AMH) level, ovarian response to gonadotropin stimulation and pregnancy rate for in vitro fertilization (IVF) patients with benign ovarian cysts.Methods:Patients with benign ovarian cysts who were admitted for cystectomy and had undergone IVF treatment were enrolled in the study. There were 373 participants with ovarian cysts underwent laparoscopic ovarian cystectomy in the experimental group. According to duration of post-surgery, there were four sub-groups: 1 year post-surgery (1Y POST), 2 years post-surgery (2Y POST), 4 years post-surgery (4Y POST) and ≥5 years post-surgery (≥5Y POST) in the experimental group. According to histopathologic types of ovarian cysts, there were two sub-groups: ovarian endometriotic cysts and ovarian non-endometriotic cysts. Two hundreds and three patients with no history of ovarian cysts and ovarian surgery were in the control group. The level of AMH and basic concentrations of follicle stimulating hormone (FSH), luteinizing hormone (LH), progesterone (P), estradiol (E 2) were measured. Antral follicle counts (AFC) were calculated. There were other study variables: total dose of gonadotropins, duration of ovarian stimulation, the number of oocyte retrieved, the number of embryo obtained, blastocyst transfer rate and pregnancy rate. Results:The control group was matched as closely as possible to the experimental group, including age, body mass index and menstrual cycle (all P>0.05). Compared to the women in control group, the women in ovarian endometriotic cystectomy sub-group had significantly higher levels of basal FSH and basal P, lower level of AMH (all P<0.05); the women in ovarian endometriotic cysts sub-group had significantly higher dose of gonadotropins (all P<0.05); the women in ovarian endometriotic cysts ≥5Y POST sub-group had significantly lower number of oocyte retrieved, lower number of embryo obtained, lower blastocyst transfer rate, and lower pregnancy rate (all P<0.05). Compared to the women in control group, the women in ovarian non-endometriotic cysts sub-group had a significantly higher level of basal FSH and basal P (all P<0.05). The women in ovarian non-endometriotic cysts sub-group had lower level of AMH, higher dose of gonadotropins, lower number of oocyte retrieved, lower number of embryo obtained, lower rate of blastocyst transfer and lower rate of pregnancy than the control group but there were no statistically significant differences among them (all P>0.05). The women with unilateral ovarian endometriotic cysts had significantly lower number of oocyte retrieved on the side of surgery than another side ( P<0.05). Conclusions:In short term laparoscopic ovarian cystectomy has no significant effect on ovarian reserve. But with long-term follow-up ovarian reserve, ovarian response to gonadotropin stimulation and pregnancy rate are decreased. The effect of laparoscopic ovarian cystectomy in benign cysts on ovarian is associated with whether or not it is the surgical side.

Aiming to solve the problem of complex structure, low flexibility and practicability for a wearable sensing data glove device of hand function evaluation system, this paper presented a wearable pressure-sensing data glove device based on visual and tactile fusion, which can stimulate the active motor function of patients. Firstly, it introduced the upper limb action research test theory, the basic test flow and the grading rules that used to evaluate the hand function. Secondly, it described the processing flow of visual and tactile information, and the hand function evaluation test method of visual and tactile fusion, which was used to achieve digital score and evaluation of the patient training process. Finally, ten patients with stroke were enrolled into the EGET system for hand function test and evaluation. The results were compared with the doctors'. The maximum relative error is 8%, and the average relative error is 4%, which means that EGET system can achieve the expected goal.

Objective: To investigate the level and trend of cardiovascular disease mortality in China from 2002 to 2016. Methods: Using data of China Health Statistics Yearbook (2003-2012) and China′s Health and Family Planning Statistical Yearbook (2013-2017),we calculated the age-standardized mortality rates (ASMR) in China. Joinpoint regression model was employed to estimate the annual percent change (APC) and average annual percent change (AAPC) of cardiovascular disease ASMR. Results: (1)The ASMR of cardiovascular disease were 225.65/100 thousands, 242.74/100 thousands, 214.63/100 thousands, 240.97/100 thousands, 195.24/100 thousands, 201.50/100 thousands, 208.83/100 thousands, 248.44/100 thousands, 261.38/100 thousands, 231.98/100 thousands, 210.25/100 thousands, 237.80/100 thousands, 235.21/100 thousands, 237.58/100 thousands,and 237.25/100 thousands from 2002 to 2016, and there was no significant difference in ASMR of cardiovascular disease (AAPC=0.2%, P>0.05) . The ASMR of chronic rheumatic heart disease decreased significantly (AAPC=-4.5%,P<0.05). There were no significant differences in ASMR of cerebrovascular disease, hypertensive heart disease, and ischemic heart disease (AAPC=0, P>0.05; AAPC=2.0%, P>0.05; AAPC=4.3%, P>0.05, respectively). (2) There were no significant differences in ASMR of cardiovascular disease from 2002 to 2016 in city and country (AAPC=-0.7%, P>0.05; AAPC=0.8%, P>0.05, respectively). The ASMR of chronic rheumatic heart disease decreased significantly in city and rural area (AAPC=-4.4%, P<0.05; AAPC=-4.6%, P<0.05, respectively). (3) There were no significant differences in ASMR of cardiovascular disease from 2002 to 2016 in male and female (AAPC=-0.3%,P>0.05; AAPC=-0.2%,P>0.05,respectively). The ASMR of chronic rheumatic heart disease decreased significantly in female (AAPC=-4.2%, P<0.05). The ASMR of ischemic heart disease increased significantly in male and female (AAPC=4.7%,P<0.05; AAPC=5.2%,P<0.05,respectively). (4) The ASMR of cardiovascular disease showed a significant upward trend in residents aged 15 to 34 from 2002 to 2016 (AAPC=3.1, P<0.05). There were no significant differences in ASMR of cardiovascular disease in residents aged 35 to 64 and ≥65 (AAPC=-0.1%, P>0.05; AAPC=-0.2%, P>0.05, respectively). Conclusion The ASMR of cardiovascular disease in China remains stable during 2002 to 2016, and the ASMR of cardiovascular disease shows upward trend among young people.
