Identification of factors affecting Oncomelania hupensis density in Eastern Dongting Lake regions / 中国血吸虫病防治杂志

Objective To evaluate the impact of water pollutants, water levels and meteorological factors on the Oncomelania hupensis density in Eastern Dongting Lake regions, so as to provide insights into schistosomiasis control. Methods O. hupensis snails were surveyed using a systematic sampling method in snail-infested marshlands in Eastern Dongting Lake regions from 2007 to 2014, and data pertaining to water pollutants, water levels and meteorological factors were collected. The duration of submergence and the date of the start of submergence were calculated. The snail density and its influencing factors were descriptively analyzed, and a linear mixed model was generated to examine the impacts of variables on the snail density. In addition, smooth curves were fitted to investigate the relationship between snail density and variables. Results The snail density appeared a fluctuation in Eastern Dongting Lake regions during the period from 2007 to 2014, with the highest density on October, 2010 (52.79 snails/0.1 m2) and the lowest density on January 2009 (2.15 snails/0.1 m2). Linear mixed-model analysis showed that permanganate index, total phosphorus and the date of the start of submergence affected the snail density (t = 6.386, −2.920 and −3.892, all P values < 0.01). Smooth curve analysis revealed that the associations of the snail density with the permanganate index and total phosphorus appeared an approximately quadratic curve. After the end of April, the earlier date of the start of submergence resulted in a higher snail density. Conclusion Permenganate index, total phosphorus and the date of the start of submergence affect the O. hupensis snail density in Eastern Dongting Lake regions.

Impact of water body environments on the microbial community of Oncomelania hupensis snails in marshlands around the eastern Dongting Lake / 中国血吸虫病防治杂志

Objective To evaluate the effects of water body environments on the microbial community of Oncomelania hupensis snails in marshlands of the eastern Dongting Lake where natural extinction of O. hupensis snails are found, so as to explore the correlation between the natural extinction of O. hupensis snails and the microbial community in snails. Methods Snails were caged water bodies in the Qianliang Lake marshland (Qianliang Lake regions) where natural extinction of snails was found and in the Junshan Park marshland (Junshan Park regions) in the eastern Dongting Lake for 30 days, and then all snails were collected and identified for survival or death. DNA sequencing of the fungi and bacteria was performed in snails before and after immersion in waters, and the biodiversity and abundance were analyzed. Results The survival rates of O. hupensis snails were 28.0% (70/250) and 64.8% (162/250) in Qianliang Lake regions and Junshan Park regions 30 days after immersion in waters, respectively (χ2 = 81.365, P < 0.01). The number of the fungal community and the biodiversity of the bacterial community were both greater in snails caged in Qianliang Lake regions post-immersion than pre-immersion, and there was a significant difference in the structure of the fungal and bacterial communities. The microbial community with a significant difference included Flavobacteriaceae,which was harmful to O. hupensis snails. Conclusion The water body environment affects the composition of the microbial community in O. hupensis snails in marshlands with natural snail distinction around the eastern Dongting Lake; however, further studies are required to investigate whether the natural distinction of snails is caused by water body environments-induced changes of the microbial spectrum in O. hupensis snails.

Objective To estimate sex based on patella measurements of Sichuan Han population by computed tomography three-dimensional volume reconstruction technique, and to explore the application value of patella in sex estimation. Methods CT three-dimensional volume reconstruction images of patella of 250 individuals were collected, the four measurement indicators including patellar length, patellar width, patellar thickness, and patellar volume were measured. The t-test was used to determine measurement indicators with sex differences. Fisher discriminant analysis was used to establish the sex discriminant function and the prediction accuracy was calculated by leave-one-out cross validation. Results The sex differences of the four measurement indicators had a statistical significance （P<0.05）. The accuracy rate of the univariate discriminant function established by the patellar length was the highest （82.0%）. The accuracy rates of the all indicators discriminant function and the stepwise discriminant function were 80.4% and 81.6%, respectively. Conclusion It is feasible and accurate to estimate sex of Sichuan Han population by patella measurements with CT three-dimensional volume reconstruction technique. The method may be used as an alternative for sex estimation of Sichuan Han population when other bones with higher accuracy are not available.

Home-based Early Intervention on Auditory and Speech Development in Mandarin-speaking Deaf Infants and Toddlers with Chronological Aged 7-24 Months / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Early auditory and speech development in home-based early intervention of infants and toddlers with hearing loss younger than 2 years are still spare in China. This study aimed to observe the development of auditory and speech in deaf infants and toddlers who were fitted with hearing aids and/or received cochlear implantation between the chronological ages of 7-24 months, and analyze the effect of chronological age and recovery time on auditory and speech development in the course of home-based early intervention.</p><p><b>METHODS</b>This longitudinal study included 55 hearing impaired children with severe and profound binaural deafness, who were divided into Group A (7-12 months), Group B (13-18 months) and Group C (19-24 months) based on the chronological age. Categories auditory performance (CAP) and speech intelligibility rating scale (SIR) were used to evaluate auditory and speech development at baseline and 3, 6, 9, 12, 18, and 24 months of habilitation. Descriptive statistics were used to describe demographic features and were analyzed by repeated measures analysis of variance.</p><p><b>RESULTS</b>With 24 months of hearing intervention, 78% of the patients were able to understand common phrases and conversation without lip-reading, 96% of the patients were intelligible to a listener. In three groups, children showed the rapid growth of trend features in each period of habilitation. CAP and SIR scores have developed rapidly within 24 months after fitted auxiliary device in Group A, which performed much better auditory and speech abilities than Group B (P < 0.05) and Group C (P < 0.05). Group B achieved better results than Group C, whereas no significant differences were observed between Group B and Group C (P > 0.05).</p><p><b>CONCLUSIONS</b>The data suggested the early hearing intervention and home-based habilitation benefit auditory and speech development. Chronological age and recovery time may be major factors for aural verbal outcomes in hearing impaired children.

Correlation of sex hormones and parathyroid hormone with biochemical markers of bone turnover in aged men / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the correlation of serum sex hormones and parathyroid hormone (PTH) with the biochemical markers of bone turnover in aged men.</p><p><b>METHODS</b>We collected the laboratory data of 465 men aged 60- 93 (73. 1 +/- 8. 3) years old, who came for routine physical examinations in our hospital. We obtained the levels of serum follicle- stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), testosterone (T), sex hormone binding globulin (SHBG), PTH, 25-hydroxy-vitamin D3 (25(OH) D3), and bone turnover markers C-terminal telopeptide of type I collagen (CTX), osteocalcin (OC) and amino-terminal propeptide of type I procollagen (PINP). We also determined free testosterone (FT) , bioactive testosterone (BT) , testosterone secretion index (TSI) and FT index (FTI), and analyzed the correlation of each index with the biochemical markers of bone turnover.</p><p><b>RESULTS</b>The concentrations of serum FSH, LH, and SHBG increased, while the levels of FT, BT, TSI, FTI, PTH, CTX, OC and PINP decreased with age, especially in those over 80 years old (P <0.05). PTH was positively correlated with CTX, OC and PINP (r =0. 227, 0. 269 and 0. 162, P <0. 01), even after the adjustment for age, while SHBG negatively correlated with OC (r = -0. 100, P <0.05). The bone turnover markers increased with the elevation of the PTH quartiles, with significant differences between the first and the fourth quartile (P <0. 01). Multiple stepwise regression analysis showed that age was correlated inversely with CTX, OC and PINP ( beta = -0. 126, -0. 141 and -0. 122, P <0.05) , PTH positively with the three markers (beta = 0. 196, 0.279 and 0.189; P <0. 001), and SHBG negatively with OC ( beta = -0. 100, P <0.05) .</p><p><b>CONCLUSION</b>Aging is the fundamental cause of reduced bone turnover in aged men. The levels serum PTH and SHBG are significantly associated with the biochemical markers of bone turnover.</p>

Parsimonious model for blood glucose level monitoring in type 2 diabetes patients / 生物医学与环境科学（英文）

To establish the parsimonious model for blood glucose monitoring in patients with type 2 diabetes receiving oral hypoglycemic agent treatment. One hundred and fifty-nine adult Chinese type 2 diabetes patients were randomized to receive rapid-acting or sustained-release gliclazide therapy for 12 weeks. Their blood glucose levels were measured at 10 time points in a 24 h period before and after treatment, and the 24 h mean blood glucose levels were measured. Contribution of blood glucose levels to the mean blood glucose level and HbA1c was assessed by multiple regression analysis. The correlation coefficients of blood glucose level measured at 10 time points to the daily MBG were 0.58-0.74 and 0.59-0.79, respectively, before and after treatment (P<0.0001). The multiple stepwise regression analysis showed that the blood glucose levels measured at 6 of the 10 time points could explain 95% and 97% of the changes in MBG before and after treatment. The three blood glucose levels, which were measured at fasting, 2 h after breakfast and before dinner, of the 10 time points could explain 84% and 86% of the changes in MBG before and after treatment, but could only explain 36% and 26% of the changes in HbA1c before and after treatment, and they had a poorer correlation with the HbA1c than with the 24 h MBG. The blood glucose levels measured at fasting, 2 h after breakfast and before dinner truly reflected the change 24 h blood glucose level, suggesting that they are appropriate for the self-monitoring of blood glucose levels in diabetes patients receiving oral anti-diabetes therapy.

Endoscopic thyroidectomy: an evidence-based research on feasibility, safety and clinical effectiveness / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The feasibility and safety of endoscopic thyroidectomy were evaluated by an approach of systematic review of published studies in the past decade.</p><p><b>METHODS</b>A database searching was performed on MEDLINE, Cochrane Database of Systematic Reviews, American College of Physicians Journal Club, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials. Both comparative and non-comparative studies about endoscopic thyroidectomy were selected and analyzed. For the comparative studies, RevMan 4.2 was used for statistical analysis; and for the non-comparative studies, data analysis was performed by SPSS 13.0.</p><p><b>RESULTS</b>Seven comparative studies involving 367 patients (video-assisted thyroidectomy (VAT), 174 patients; conventional thyroidectomy (CT), 193 patients) were included in VAT-CT group. Age, gender, operative types, and pathological diagnosis were similar. Compared with CT, the mean operative time for VAT was significantly longer (VAT, 80.0 minutes; CT, 61.9 minutes, P < 0.01), but the postoperative hospital stay was shorter (VAT, 1.7 days; CT, 2.5 days, P < 0.01). The complication rate for VAT was 6.9%, while that for CT was 9.3% (P = 0.35). Three studies analyzed the postoperative pain and cosmetic evaluation, and indicated that the VAT group was superior to the CT group, but there was no significant difference after a meta-analysis. Three comparative studies involving 273 patients (totally endoscopic thyroidectomy (TET), 145 patients; CT, 128 patients) were included in TET-CT group and the results generally resembled that of VAT-CT group. There were 18 and 14 non-comparative studies reporting the results of VAT and TET, respectively. The mean operative time for VAT was 76.8 minutes compared with 135.8 minutes for TET. The postoperative hospital stay was 1.8 and 3.8 days for VAT and TET respectively. The rates of conversion to open surgery for VAT and TET were similar (VAT, 2.8%; TET, 3.9%, P = 0.105). The complication rate for VAT was 8.6%, while that for TET was 3.5% (P < 0.01).</p><p><b>CONCLUSIONS</b>The feasibility and safety of endoscopic thyroidectomy were initially verified and accepted, and it should be considered as a valid option, offering some advantages to patients in terms of cosmetic results and postoperative distress.</p>

<p><b>OBJECTIVE</b>To evaluate the performance of 18F-FDG three-head tomography with coincidence imaging and serum tumor marker assays in identifying lung lesions in 104 patients with abnormal findings on chest X-ray or computer tomography.</p><p><b>METHODS</b>A prospective evaluation of 18F-FDG coincidence imaging and the measurement of 3 serum markers for lung cancer ( carcinoembryonic antigen, CYFRA21-1 and neuron specific enolase) were performed within one week in 104 inpatients with suspected lung malignancy. All images were analyzed visually. It was considered positive for malignancy if the 18F-FDG uptake was increased relative to that in the adjacent lung tissue, and was focal. The serum tumor marker test was considered positive for malignancy if the serum level of at least one marker was elevated.</p><p><b>RESULTS</b>66 patients were proven to have lung cancer by pathology, and 38 patients had benign lung diseases. The sensitivity, specificity, accuracy of 18F-FDG coincidence imaging and serum tumor markers in assessing lung cancers were 80. 0% , 77. 2% , 77. 9% and 56. 0% , 60. 9%, 64. 4% , respectively. 18F-FDG coincidence images in assessing lung lesions showed significantly higher sensitivity, specificity and accuracy than serum tumor markers. Four patients with lung cancer had negative findings on 18F-FDG coincidence images but showed positive serum markers.</p><p><b>CONCLUSION</b>18F-FDG coincidence imaging is a powerful tool for evaluating patients with lung lesions suggestive of malignancy. Although the determination of serum marker levels is less accurate than 18F-FDG coincidence imaging, the combination of a positive 18F-FDG coincidence result and positive tumor markers may be helpful in improving the diagnosis of lung cancers.</p>
