Objective To evaluate the value of continuous glucose monitoring system (CGMS) in the gestational patients with impaired glucose regulation. Methods The glucose level in the subcutaneous tissue was monitored by CGMS for 3 days in 6 patients with gestational diabetes mellitus (GDM) and 6 patients with gestational impaired glucose tolerance (GIGT). The fluctuation coefficient of blood glucose, percentage of hyperglycemic time, and percentage of hypoglycemic time were calculated. Results As shown by CGMS, the fluctuation coefficient of blood glucose, mean glucose level, percentage of hyperglycemic time, percentage of hypoglycemic time, mean fasting blood glucose, and mean postprandial blood glucose (PBG) levels were not significantly different between GDM group and GIGT group (P > 0. 05). The time for reaching the peak PBG level ranged 90-120minutes in both two groups (P > 0. 05). No sensor-related adverse events were noted. Conclusions It is safe to apply CGMS sensor in pregnant women. The blood glucose profiles are comparable between GDM and GIGT patients by CGMS; therefore, control of blood glucose should be equally strict in patients with GIGT as those with GDM.

Objective To understand the status of schistosomiasis of staff in the Hydrology Bureau of Yangtze Water Re-sources Committee and the Oncomelania hupensis snail condition of their work areas in 2013 so as to provide the evidences for the schistosomiasis control in the industry. Methods The physical examination data about schistosomiasis of the staff from 2006 to 2013 were collected and analyzed to understand the schistosomiasis prevalence condition of the staff and the changes of their liver parenchyma. Meanwhile the snail status in the work areas was surveyed. Results There were 1 393 staff involved in the physical examinations of schistosomiasis in 2003 197 of them were schistosomiasis patients the prevalence rate was 14.14% and no new acute schistosomiasis case occurred. The cases whose liver parenchyma were classified as Grade 0 ⅠⅡ Ⅲoccupied 28.9% 67.0% 3.05%and 1.02% respectively. A total of 24 work areas were involved in the snail survey and 71 snails were captured. Among the whole snails captured 39 were living snails but no schistosome infected snails were found. Conclusions The prevalence rate of schistosomiasis in staff of the Hydrology Bureau of Yangtze Water Resources Com-mittee is relatively high so the schistosomiasis surveillance as well as the snail survey and control still should be carried out con-sistently.

Objective To evaluate the accuracy, of different threshold segmentation of 18FDG PET for target volume delineation of non-small cell lung cancer(NSCLC) and the potential influence on radiotherapy treatment planning. Methods Eight NSCLC patients who had tumor with clear margin on CT scan and the amplitude of tumor movements not more than 5 mm were enrolled. PET scans were carried out at 1 h after intravenous injection of 18FDG with CT image for attenuation revisement. Gross target volume (GTV) delineated on CT image ( GTVCT ) was used as the standard. Then, GTVs were delineated on PET image with three different threshold segmentation of 42% Imax(total) (42% of maximum voxel intensity within the tumor) ,Iback + 20% Imax-back(max) (mean background intensity + 20% of normalized background-subtracted maximum voxel intensity within the tumor) and Iback -20% Imax-back(slice) (mean background intensity + 20% of normalized background-subtracted maximum voxel intensity of each slice within the tumor) ,the corresponding GTV was named as GTV42%, GTV20%max and GTV20%slice. Both the size of GTV42%, GTV20%max, GTV20%slice and GTVCT,and the coverage over GTVCT for each GTV were compared. A three dimensional margin of 1 cm were added to GTVCT, GTV42%, GTV20%max and GTV20%slice to form corresponding PTVCT, PTV42%, PTV20%max and PTV20%slic e. Three dimensional conformal radiotherapy treatment plans were designed based on PTVCT,PTV42% , PTV20%max and PTV20%slice respectively for each patient. The prescription dose of all PTVs was 66 Gy in 33 fractions in 6.6 weeks. Both the volume accepting dose less than 95% of prescription dose within PTVCT ( VPTV ) and the lung V20 were compared among the four plans based on different PTVs. Tumor control probability(TCP) as well as lung normal tissue complication probability (NTCP) were also compared. Resuits Eight patients were enrolled in this study. Median deviation of volume between GTVPET and GTVCT were -54.1% , -21.5 % and 5.3 % for GTV42% , GTV20%max and GTV20%slice, respectively. Median coverage over GTVCT of GTV42% , GTV20%max and GTV20%slice was 45.9% ,78.0% and 95.3% respectively( F = 57.50,P<0.01). Median 7.5% of VPTV was observed for radiotherapy treatment plan based on PTV42% ,which meant that it might induce median 1% decrease of TCP comparing with that of radiotherapy treatment plan based on PTVCT. Whereas,there were only 1.3% and 0.0% of VPTV for treatment plans based on PTV20%max and PTV20%slice respectively. As far as TCP was concemed, both PTV20%max group and PTV20%slice group were superior to PTV42% group,there was no significant difference among PTV20%max group, PTV20%slice group and PTVCT group. Lung V20 and lung NTCP showed no significant difference among all groups. Conclusions The threshold segmentation of Iback + 20% Imax-back(slice) , being slice specialized, might be an optimal threshold segmentation for target volume delineation of lung caner. Independent of information of target volume provided by CT scan in advance,it is recommended to use for the target volume delineation of NSCLC with atelectasis.

Objective:To analyze the intervention effect of rehabilitation platform-based online psycho-education on patients with bipolar disorder (BD) in remission stage.Methods:In this randomized controlled study, 91 patients with BD in remission stage who attended the community health center in Xicheng District, Beijing from July to August 2021 were randomly divided into a test group (46 cases) and a control group (45 cases) according to a 1∶1 ratio using the random number table. Baseline data were collected from both groups, and the control group received conventional medication and community telephone follow-up, while the test group was given online mental health education in the form of a WeChat subscription number on this basis, including BD mental health education course push (twice a week) and disease self-management (daily recording of mood, sleep, medication, exercise and gratitude diary), and the intervention period was 6 months in both groups. During the intervention, one patient in the test group was admitted to hospital due to exacerbation of mental illness and the trial was terminated. A total of 90 cases were included in the study. The scores of Medication Adherence Rating Scale (MARS), Hamilton Depression Scale (HAMD), Young Mania Rating Scale (YMRS) and Perceived Devaluation-Discrimination Scale (PDD) were assessed at baseline, after 3 months and 6 months of intervention in both groups, respectively. And the differences in baseline data between the two groups were compared using two independent samples t test and χ2 test, and the repeated-measures ANOVA was used to compare the differences in MARS, HAMD, YMRS, and PDD scores between the two groups before and after the intervention, and to analyze the intervention effects of network mental health education based on the rehabilitation platform on patients in remission stage of BD. Results:After 6 months of intervention, MARS scores in the test group was significantly higher than that in the control group [(8.47±1.75) vs (7.47±1.85)], and was significantly higher than that at baseline (7.36±2.13) and after 3 months of intervention (8.04±1.68) (all P<0.05). YMRS and PDD scores in the test group were significantly lower than those at baseline after 3 and 6 months of intervention [YMRS, 2.0(1.0,4.0),2.0(0,3.0) vs 3.0(1.0,5.5); PDD, (31.18±4.65), (30.13±4.76) vs (32.51±4.51)] (all P<0.05); the differences in YMRS and PDD scores in the control group were not statistically significant (all P>0.05). There was no statistically significant difference in HAMD scores between the two groups before and after the intervention (all P>0.05). Conclusion:Combining mental health education based on rehabilitation platform with conventional medication and community management can significantly improve the medication compliance of patients with BD in remission stage, and improve their manic symptoms and reduce the stigma of the disease.

The purification of parasite-infected erythrocytes from whole blood containing
leucocytes is crucial for many downstream genetic and molecular assays in parasitology.
Current methodologies to achieve this are often costly and time consuming. Here, we
demonstrate the successful application of a cheap and simple Non-Woven Fabric (NWF) filter
for the purification of parasitized red blood cells from whole blood. NWF filtration was
applied to the malaria-parasitized blood of three strains of mice, and one strain of rat, and to
Babesia gibsoni parasitized dog blood. Before and after filtration, the white blood cell (WBC)
removal rates and red blood cell (RBC) recovery rates were measured. After NWF filter
treatment of rodent malaria-infected blood, the WBC removal rates and RBC recovery rates
were, for Kunming mice: 99.51%±0.30% and 86.12%±8.37%; for BALB/C mice: 99.61%±0.15%
and 80.74%±7.11%; for C57 mice: 99.71%±0.12% and 84.87%±3.83%; for Sprague-Dawley rats:
99.93%±0.03% and 83.30%±2.96%. Microscopy showed WBCs were efficiently removed from
infected dog blood samples, and there was no obvious morphological change of B. gibsoni
parasites. NWF filters efficiently remove leukocytes from malaria parasite-infected mouse
and rat blood, and are also suitable for filtration of B. gibsoni-infected dog blood.
