Objective To evaluate the effect of isoflurane or sevoflurane inhalation before and after gestation on the offspring brain development. Methods Thirty female adult Sprague Dawley rats were randomly assigned into 5 groups(n=6 each):control group(group C),group that ex?posed to isoflurane with the concentration of 1.6%for 6 hours before gestation(group BI),group that exposed to isoflurane with the concentration of 1.6%at the 6th,10th,14th and 18th day for 6 hours(group PI),group that exposed to sevoflurane with the concentration of 2.4%for 6 hours before gestation(group BS),and group exposed to sevoflurane with the concentration of 2.4%at the 6th,10th,14th and 18th day for 6 hours after gestation (group PS). Twelve offspring rats from pregnant rats in each group were chosen on the day of birth(T1),and 7th,14th and 28th days after birth(T2, T3 and T4)and sacrificed,and the hippocampi were then isolated. Hematoxylin and eosin stain were adopted to observe the tissue pathological change. Electron microscope was used to observe the neuron ultrastructure change of hippocampus. Immolunohistochemistry was used to detect cas?pase?3,the expression of growth associated protein?43(GAP?43)and neuronal nitric oxide synthase(nNOS). Results Compared with group C, no significant change was found in caspase?3,GAP?43 and nNOS expression in offspring rat hippocampus in groups BI and BS(P>0.05),and no damage change in hippocampal was seen by HE staining and electron microscopy. In group PI and PB,the expression of caspase?3 was significantly up?regulated,the expression of GAP?43 and nNOS was down?regulated at T1 to T3(P<0.01),and structural changes in cell were seen by electron microscopy. In group PI,significant pathological changes in hippocampal were seen by HE staining at T1 to T3. Compared with group PI,the expres?sion of GAP?43 and nNOS was significantly up?regulated(P<0.01),and the expression of caspase?3 was down?regulated at T1 to T3(P<0.01). Conclusion Isoflurane or sevoflurane inhalation before gestation does not affect the offspring brain development,while isoflurane or sevoflurane in?halation after gestation can induce transient abnormal change of offspring brain development,and isoflurane′s toxicity was greater than sevoflurane.

Objective To evaluate the effect of isoflurane or sevoflurane inhalation before and after gestation on the N-methyl-D-aspartate (NMDA) receptor expression in offspring rat hippocampus.Methods Thirty female adult Sprague-Dawley rats,aged 3 months,weighing 250-300 g,were randomly assigned into 5 groups (n =6 each):control group (group C),exposure to isoflurane before gestation group (group BI),exposure to isoflurane during gestation period group (group PI),exposure to sevoflurane before gestation group (group BS),exposure to sevoflurane during gestation period group (group PS).The rats inhaled 1.6％ isoflurane for 6 h at 1 day before gestation in group BI.The rats inhaled 1.6％ isoflurane for 6 h at 6,10,14 and 18 day gestation in group PI.The rats were exposed to 2.4％ sevoflurane for 6 h before gestation in group BS.The rats were exposed to 2.4％ sevoflurane for 6 h at 6,10,14 and 18 day gestation in group PS.Twelve offspring rats from pregnant rats in each group were chosen on the day of birth (T1),and 7th,14th and 28th days after birth (T2-4) and sacrificed,and the hippocampi were then isolated for determination of the expression NMDA receptor (NR1,NR2A and NR2B).Results Compared with group C,no significant change was found in NMDA receptor expression in off spring rat hippocampus in groups BI and BS (P ＞ 0.05),and the expression of NR1 and NR2A protein and mRNA was significantly up-regulated,and the expression of NR2B protein and mRNA was down-regulated at T1-3 (P ＜0.05),and no significant change was found in NMDA receptor expression at T4 in groups PI and PS (P ＞ 0.05).Compared with group PI,the expression of NRI and NR2A protein and mRNA was significantly up-regulated,and the expression of NR2B protein and mRNA was down-regulated at T1 3 (P ＜ 0.05 or 0.01),and no significant change was found in N MDA receptor expression at T4 in group PS (P ＞ 0.05).Conclusion Isoflurane or sevoflurane inhalation before gestation does not affect the NMDA receptor expression in offspring rat hippocampus,while isoflurane or sevoflurane inhalation after gestation can induce abnormal expression of the NMDA receptor in offspring rat hippocampus,which may result in apoptosis in hippocampal cells and abnormality in the development of nervous system and cognitive function.

Objective:To analyze the influenza vaccination status of chronic disease management patients in Qingpu district of Shanghai and the vaccination characteristics of different characteristic populations, so as to provide scientific basis for improving the influenza vaccination rate of chronic disease patients in the community.Methods:By comparing the data of Shanghai chronic disease management information system, immunization planning information system and medical association platform, 89 453 subjects who met the inclusion and exclusion criteria in Qingpu district were selected as the research objects. The vaccination coverage rate of the study subjects was calculated according to gender, age group, urban and rural distribution, occupation, chronic disease type and quantity, and the vaccination coverage rate of different subgroups was compared to analyze the influencing factors of vaccination coverage rate.Results:Most of the 89 453 patients with chronic diseases were 60 years old and above (71.93%). Patients with hypertension, diabetes, chronic obstructive pulmoriary disease (COPD) and three chronic diseases accounted for 87.12%, 28.67%, 8.71% and 1.83%, respectively. Influenza vaccination coverage in the 2016/2017 flu season was low, at 0.32%. Influenza vaccination coverage rate of women (0.37%) was higher than that of men (0.27%), which was 1.41 times respectively(95% CI: 1.16, 1.72) that of men patients. The coverage rate of influenza vaccination for the 70-79 year-old group was the highest (0.74%), which was 1.74 times respectively(95% CI: 1.39, 2.19) that of 60-69 year-old patients. The vaccination coverage rate of government departments and institutions was the highest (1.14%), which was 12.58 times respectively(95% CI: 4.52, 34.99) that of retirees. The vaccination rate of COPD patients (3.68%) was 2.50 times (95% CI: 1.66, 3.77) higher than that of patients without COPD.Conclusions:Influenza vaccination rate for chronic disease management patients in Qingpu district of Shanghai is low. Gender, occupation, age and types of chronic diseases are the influencing factors. Patients with chronic disease management should be included in the priority vaccination targets for influenza vaccines, and vaccination intervention for occupational chronic diseases such as non-retired agriculture and forestry patients, especially male patients, should be strengthened to improve influenza vaccination coverage rate.

Objective:To develop a wireless sensor module for wound temperature and pressure (hereinafter referred to as wireless sensor module), and to carry out related characteristic test and biosafety evaluation.Methods:(1) The structure and working mode of the wireless sensor module were designed. The temperature and humidity sensor welded at one end of the flexible cable and the pressure sensor were simultaneously connected with the printed circuit board, which was welded with the Bluetooth transmitter, microprocessor, and power interface to establish a wireless sensor module. A mobile data receiving application was developed and the monitoring values of the wireless sensor module exposed to the air were read through the Bluetooth function on the smart phone. (2) The temperature of a 35-42 ℃ hot water bag was measured by the wireless sensor module and an infrared thermometer at the same time, and 30 pairs of data were compared with correlation analysis performed. (3) The vacuum sealing drainage material was pasted on the arm of the second author, and the wireless sensor module was placed in the condition of negative pressure. The negative pressure values measured by the wireless sensor module and the negative pressure meter values were recorded at the same time, and 14 pairs of data were compared with correlation analysis performed. (4) The corresponding material extract was prepared by adding 1 mL normal saline per 3 square centimeters surface area of the pressure sensor or flexible cable with temperature and humidity sensor welded respectively. Twenty 6-8 week-old female C57BL/6 mice were weighed before experiment and divided into pressure sensor extract group, flexible cable extract group, mixed extract group, and normal saline group according to the random number table ( n=5). The abnormal toxic reactions of mice were observed after intraperitoneal injection of pressure sensor extract, flexible cable with temperature and humidity sensor welded extract, 1∶1 mixed extract of pressure sensor extract and flexible cable with temperature and humidity sensor welded extract, and normal saline for 50 mL/kg in corresponding groups. The body mass of mice was weighed at 24, 48, and 72 hours after injection, and the toxicity of the materials was evaluated comprehensively. (5) Four Japanese big ear white rabbits aged 3-6 months were selected, and there was no limit between male and female. Two regions on the left side of the spine were applied with aseptic gauze as aseptic gauze group, and two areas on the right side of the spine were applied with wireless sensor module as wireless sensor module group. The skin status of each region was evaluated at 1, 12, 24, 48 hours after application, and the score according to the skin irritation score standard was recorded. (6) The corresponding material extract was prepared by adding 1 mL serum-free Dulbecco′s modification of Eagle′s medium (DMEM) per 1 square centimeter surface area of the pressure sensor or flexible cable with temperature and humidity sensor welded respectively. L-929 fibroblasts were divided into pressure sensor extract group, flexible cable extract group, phenol control group, and medium control group. The corresponding extract was added in the first two groups, the phenol control group was added with 64 g/L phenol, and the medium control group was cultured with serum-free DMEM. The total volumes of the above four groups were all 100 μL. The absorbance values on the 2nd, 4th, 7th day of culture were detected by methyl thiazolyl tetrazolium method to calculate the cell proliferation rate ( n=6 at each time point) and to grade the cytotoxicity. Data were statistically analyzed with paired samples t test, Wilcoxon signed rank test, Pearson correlation analysis, Spearman correlation analysis, Mann-Whitney U test, analysis of variance for repeated measurement, analysis of variance for factorial design, one-way analysis of variance, and Bonferroni correction. Results:(1) The smart phone successfully received the air temperature, humidity, and pressure information detected by the wireless sensor module through the Bluetooth function. (2) The temperature of the hot water bag measured by the wireless sensor module was (37.7±1.7) ℃, which was close to (37.7±1.7) ℃ of the infrared thermometer ( t=-0.112, P>0.05), and there was a significant positive correlation between them ( r=0.996, P<0.01). (3) The negative pressure of arm under negative pressure material measured by the wireless sensor module was -36.7 (-38.8, -27.4) kPa, which was significantly lower than -22.7 (-32.7, -12.5) kPa of negative pressure meter ( Z=-3.235, P<0.01), but there was a significant positive correlation between their absolute values ( ρ=1.000, P<0.01). (4) There was no abnormal toxic reaction in all groups of rats, and there was no statistically significant difference in body mass among the four groups of mice ( F=3.132, P>0.05). (5) The scores of skin irritation in application region of rats in the two groups were similar at 1, 12, 24, 48 hours after application ( Z=-1.000, <0.001, -0.620, <0.001, P>0.05). (6) At each time point of culture, compared with that of medium control group, the cell proliferation rate increased significantly in pressure sensor extract group and flexible cable extract group ( P<0.01) but decreased significantly in phenol control group ( P<0.01). On the 2nd, 4th, 7th day of culture, the cytotoxicity grade of phenol control group was 1, 1, and 2 respectively, and the cytotoxicity grade of each extract group was 0. Conclusions:The wireless sensor module integrates temperature, humidity, and pressure sensors, which can monitor local temperature and pressure and realize the visualization of parameters on the mobile application program. The measurement of temperature is accurate and the pressure measurement results are consistent with the values of the negative pressure meter with good biosafety. It possesses a big value in clinical application and prospects for development.

Objective:To evaluate the effect of clinic standardized blood pressure measurement model (SBPM) applying to first blood pressure measurement among community population aged 35 years old and above.Methods:SBPM was implemented in the community health service center of Dapuqiao street, Huangpu district of Shanghai from June 1, 2018, and the data between June 1 and December 31, 2018 was used as the SBPM data. The first-diagnosis blood pressure measurement data in this center between June 1 and December 31, 2017 was used as the conventional measurement (CM) model data. The detection rate of elevated blood pressure under SBPM was standardized according to the gender and age distribution of subjects in CM. The equilibrium of the value distribution of the end digit of blood pressure value in different pressure-measuring models and difference of elevated blood pressure rate of subjects with different characteristics and seasons were analyzed by using the χ 2 test, and the difference of standardized elevated blood pressure rate in different pressure-measuring models was analyzed by using the U test. Results:The SBPM included 1 548 subjects and 639 (41.28%) of them were males. The CM included 2 952 inpatients and 1 196 (40.51%) of them were males. The frequency of the end digit of blood pressure in SBPM ranged from 9.04% to 10.72%, and both systolic and diastolic blood pressure showed a balanced distribution of end digit ( P values were 0.996 and 0.981 respectively). The frequency of blood pressure end digital in the CM ranged from 0.37% to 67.92%, and both systolic and diastolic blood pressure showed an unbalanced distribution (both P values <0.001). The crude rate and standardized elevated blood pressure rate in SBPM were 23.19% (359/1 548) and 23.05%, which were higher than that in CM, about 7.22% (213/2 952) (both P values <0.001). The elevated blood pressure rate in SBPM in summer, autumn and winter was 18.85% (141/748), 26.72% (152/591) and 31.58% (66/209), respectively, which was higher than that in CM, about 6.28% (91/1 450), 7.20% (82/1 139) and 11.02% (40/363), respectively (all P values <0.001). Conclusion:The quality of blood pressure data and the efficiency of hypertension screening of SBPM are better than those of CM when applying to first blood pressure measurement among community population aged 35 years old and above.

ObjectiveTo evaluate the effect of standardized blood pressure measurement in consulting room （SBPM） model on blood pressure screening of non-hypertensive patients in community. MethodsFour communities were randomly selected from Fengxian District of Shanghai， and non-hypertensive patients in the communities were included for screening. Based on the communities， participants were further classified into the intervention group and control group. A one-year intervention study was conducted from January 1， 2021 to December 31， 2021. The intervention group received the intervention measures of standardized measurement， and the control group remained the routine measurement. The distribution of blood pressure values and last digit of the values between the intervention group and control group were tested using Chi-square test and normality test. Then changes in abnormal blood pressure rate before and after the intervention were determined by double difference method. Statistical analysis was performed using SPSS 20.0. ResultsA total of 15 368 participants were included in the intervention group， and 19 811 participants in the control group. After the intervention， range of the last digit of blood pressure values in the intervention group was 9.55%‒10.41%， of which that of systolic and diastolic blood pressure were equally distributed （P=0.932 and 0.871， respectively）. The range of the last digit in the control group was 1.31%‒42.58%， of which that of systolic and diastolic blood pressure showed unequal distribution （P<0.001）. Through one-year standardized measurement intervention， the abnormal rate of blood pressure in the intervention group was 26.29%， which was 7.61 times as high as that in the control group （OR=7.55， 95%CI： 6.75‒8.57， P<0.001）. ConclusionStandardized blood pressure measurement in consulting room is suitable for the screening of blood pressure measurement in community， which has higher data quality than that of routine measurement.
