Abstract
Objective: To explore potential predictors of refractory Mycoplasma pneumoniae pneumonia (RMPP) in early stage. Methods: The prospective multicenter study was conducted in Zhejiang, China from May 1st, 2019 to January 31st, 2020. A total of 1 428 patients with fever >48 hours to <120 hours were studied. Their clinical data and oral pharyngeal swab samples were collected; Mycoplasma pneumoniae DNA in pharyngeal swab specimens was detected. Patients with positive Mycoplasma pneumoniae DNA results underwent a series of tests, including chest X-ray, complete blood count, C-reactive protein, lactate dehydrogenase (LDH), and procalcitonin. According to the occurrence of RMPP, the patients were divided into two groups, RMPP group and general Mycoplasma pneumoniae pneumonia (GMPP) group. Measurement data between the 2 groups were compared using Mann-Whitney U test. Logistic regression analyses were used to examine the associations between clinical data and RMPP. Receiver operating characteristic (ROC) curves were used to analyse the power of the markers for predicting RMPP. Results: A total of 1 428 patients finished the study, with 801 boys and 627 girls, aged 4.3 (2.7, 6.3) years. Mycoplasma pneumoniae DNA was positive in 534 cases (37.4%), of whom 446 cases (83.5%) were diagnosed with Mycoplasma pneumoniae pneumonia, including 251 boys and 195 girls, aged 5.2 (3.3, 6.9) years. Macrolides-resistant variation was positive in 410 cases (91.9%). Fifty-five cases were with RMPP, 391 cases with GMPP. The peak body temperature before the first visit and LDH levels in RMPP patients were higher than that in GMPP patients (39.6 (39.1, 40.0) vs. 39.2 (38.9, 39.7) ℃, 333 (279, 392) vs. 311 (259, 359) U/L, both P<0.05). Logistic regression showed the prediction probability π=exp (-29.7+0.667×Peak body temperature (℃)+0.004×LDH (U/L))/(1+exp (-29.7+0.667×Peak body temperature (℃)+0.004 × LDH (U/L))), the cut-off value to predict RMPP was 0.12, with a consensus of probability forecast of 0.89, sensitivity of 0.89, and specificity of 0.67; and the area under ROC curve was 0.682 (95%CI 0.593-0.771, P<0.01). Conclusion: In MPP patients with fever over 48 to <120 hours, a prediction probability π of RMPP can be calculated based on the peak body temperature and LDH level before the first visit, which can facilitate early identification of RMPP.

Abstract
Objective: Based on a cohort and intervention study of the Eastern Chinese Student Surveillance, Cohort and Intervention Study (ES-SCI), this research aims to explore the correlation between monitor of the school environment and longitudinal data on myopia and provide evidence for the government myopia intervention strategy. Methods: This survey adopts the stratified cluster sampling method with the school as the unit. Students from grade 1 to grade 3 were selected according to the whole class to monitor the school environment in the classroom. Students will use the full-automatic computer optometer (TOPCON RM800) to conduct optometry from 2019 to 2021 under the condition of mydriasis to perform refractive eye examinations. Meantime eye axis length monitoring was also conducted. Cox proportional risk regression model was used to explore the relationship between school environmental monitoring and the occurrence and development of students' myopia. Results: From 2019 to 2021, 2 670 students from 77 classrooms participated in the observation study. The students' diopter after right/left eye mydriasis decreased in varying degrees (P<0.001), and the axial length of the right/left eye increased in various degrees (P<0.001). The weighted qualified rate of per capita area of primary school classrooms increased from 18.0% in 2019 to 26.0% in 2021, the weighted average illuminance pass rate of blackboard surface increased from 23.8% in 2019 to 26.4% in 2021, and the weighted average illuminance pass rate of classroom table decreased from 86.7% in 2019 to 77.5% in 2021. The trend chi-square test was significant (P<0.05). Cox proportional risk regression showed that after correcting for the grade, gender, parental myopia, diet, sleep, near work (sitting posture, working time, electronic mobile equipment, eye exercises), and outdoor activities, the per capita area of 1.36- m2 was the protective factor of eye axis length (HR=0.778, 95%CI: 0.659-0.918, P=0.003); The average reflection ratio of blackboard 0.15-0.19 was the protective factor of eye axis length (HR=0.685, 95%CI: 0.592-0.793, P<0.001); The average illumination of the blackboard 150-, 300-, 500- lx was the protective factor of the eye axis length (HR=0.456, 95%CI: 0.534-0.761, P<0.001; HR=0.794, 95%CI: 0.705-0.895, P<0.001; HR=0.690, 95%CI: 0.619-0.768, P<0.001). The blackboard evenness 0.40-0.59 was the risk factor of eye axis length (HR=1.528, 95%CI: 1.018-2.293, P=0.041), and the blackboard evenness 0.80- was the protection factor of eye axis length (HR=0.542, 95%CI: 0.404-0.726, P<0.001). The evenness of the desktop 0.40-0.59 was the protective factor of eye axis length (HR=0.820, 95%CI: 0.698-0.965, P=0.017). The average illuminance of 150-, 300-, 500- lx was the protective factor of a diopter (HR=0.638, 95%CI: 0.534-0.761, P<0.001; HR=0.911, 95%CI: 0.848-0.978, P=0.011; HR=0.750, 95%CI: 0.702-0.801, P<0.001). The average illumination of desktop 500- lx was a protective factor of a diopter (HR=0.855, 95%CI: 0.763-0.958, P=0.007). Conclusion: School environmental monitoring indicators, such as meeting per capita area standards, passing blackboard, and desk top-related indicators, all play protective effects on myopia development in students.

Abstract
Clinical classification of advanced schistosomiasis japonica is important for treatment options and prognosis prediction. Network analysis was used to solve the problem of complexity and co-occurrence complications in classification of advanced schistosomiasis. A total of 4,125 retrospective patients were enrolled and divided randomly into a training cohort (n = 2,888) and a validation cohort (n = 1,237). Network analysis was used to cluster the isolated complications of advanced schistosomiasis. The accuracy of the network was evaluated. Nomograms based on the clustered complications were built to predict 1- to 5-year survival rates in advanced schistosomiasis. The predictive performance of the nomogram was also evaluated and validated. Fifteen isolated complications were identified: metabolic syndromes, minimal hepatic encephalopathy, hepatic encephalopathy, chronic obstructive pulmonary disease, pulmonary hypertension, respiratory failure, right heart failure, gastroesophageal variceal bleeding, gastrointestinal ulcer bleeding, splenomegaly, fibrosis, chronic kidney disease, ascites, colorectal polyp, and colorectal cancer. Through network analysis, three major clustered complications were achieved-namely, schistosomal abnormal metabolic syndromes (related to chronic metabolic abnormalities), schistosomal abnormal hemodynamics syndromes (related to severe portal hypertension and portosystemic shunting), and schistosomal inflammatory granulomatous syndromes (related to granulomatous inflammation). The nomograms showed a good performance in prognosis prediction of advanced schistosomiasis. The novel classification-based nomogram was useful in predicting the survival rate in advanced schistosomiasis japonica.

Abstract
This study aimed to explore the infrared manifestation and role of brown adipose tissue(BAT) in phlegm-dampness me-tabolic syndrome(MS), and to provide objective basis for clinical diagnosis and treatment of phlegm-dampness MS. Subjects were selected from the department of endocrinology and ward in the South District of Guang'anmen Hospital, China Academy of Chinese Medical Sciences from August 2021 to April 2022, including 20 in healthy control group, 40 in non phlegm-dampness MS group and 40 in phlegm-dampness MS group. General information, height and weight of the subjects were collected and body mass index(BMI) was calculated. Waist circumference(WC), systolic blood pressure(SBP) and diastolic blood pressure(DBP) was measured. Triglyceride(TG), high density lipoprotein cholesterol(HDL-C), fasting blood glucose(FBG), fasting insulin(FINS), leptin(LP), adiponectin(ADP) and fibroblast growth factor-21(FGF-21) were detected. The infrared thermal image of the supraclavicular region(SCR) of the subjects before and after cold stimulation test was collected by infrared thermal imager and the changes of infrared thermal image in the three groups were observed. In addition, the differences in the average body surface temperature of SCR among the three groups were compared, and the changes of BAT in SCR were analyzed. The results showed compared with the conditions in healthy control group, the levels of WC, SBP, DBP, TG and FPG in MS groups were increased(P<0.01), and the HDL-C level was decreased(P<0.01). Compared with non phlegm-dampness MS group, phlegm-dampness MS group had higher conversion score of phlegm dampness physique(P<0.01). According to the infrared heat map, there was no difference in the average body surface temperature of SCR among the three groups before cold stimulation. while after cold stimulation, the average body surface temperature of SCR in MS groups was lower than that in healthy control group(P<0.05). After cold stimulation, the maximum temperature of SCR and its arrival time in the three groups were as follows: healthy control group(3 min)>non phlegm-dampness MS group(4 min)>phlegm-dampness MS group(5 min). The thermal deviation of SCR was increased and the average body surface temperature of left and right sides were higher(P<0.01) in healthy control group and non phlegm-dampness MS group, while the thermal deviation of SCR did not change significantly in the phlegm-dampness MS group. Compared with that in healthy control group, the elevated temperature between left and right sides was lower(P<0.01, P<0.05), and compared with that in non phlegm-dampness MS group, the elevated temperature of left side was lower(P<0.05). The changes of the average body surface temperature of SCR in the three groups were in the order of healthy control group>non phlegm-dampness MS group>phlegm-dampness MS group. Compared with the conditions in healthy control group and non phlegm-dampness MS group, FINS, BMI and FGF-21 levels were increased(P<0.01,P<0.05), while ADP level was decreased(P<0.01, P<0.05) in phlegm-dampness MS group. Moreover, the LP level in phlegm-dampness MS group was higher than that in non phlegm-dampness MS group(P<0.01). It was observed in clinical trials that after cold stimulation, the average body surface temperature of SCR in MS patients was lower than that of the healthy people; the thermal deviation of SCR did not change significantly in the phlegm-dampness MS patients, and the difference in their elevated temperature was lower than that in the other two groups. These characteristics provided objective basis for clinical diagnosis and treatment of phlegm-dampness MS. With abnormal BAT related indicators, it was inferred that the content or activity of BAT in SCR of phlegm-dampness MS patients were reduced. There was a high correlation between BAT and phlegm-dampness MS, and thus BAT might become an important potential target for the intervention in phlegm-dampness MS.

Abstract
Objective: To compare oxytocin combined with ergometrine with oxytocin alone in terms of primary prophylaxis for postpartum hemorrhage (PPH) at the time of cesarean section (CS). Methods: This was a multicenter double-blind randomized controlled interventional study comparing ergometrine combined with oxytocin and oxytocin alone administered at CS. From December 2018 to November 2019, a total of 298 parturients were enrolled in 16 hospitals nationwide. They were randomly divided into experimental group (ergometrine intra-myometrial injection following oxytocin intravenously; 148 cases) and control group (oxytocin intra-myometrial injection following oxytocin intravenously; 150 cases) according to 1∶1 random allocation. The following indexes were compared between the two groups: (1) main index: blood loss 2 hours (h) after delivery; (2) secondary indicators: postpartum blood loss at 6 h and 24 h, placental retention time, incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution; (3) safety indicators: nausea, vomiting, dizziness and other adverse reactions, and blood pressure at each time point of administration. Results: (1) The blood loss at 2 h after delivery in the experimental group [(402±18) ml] was less than that in the control group [(505±18) ml], and the difference was statistically significant (P<0.05). (2) The blood loss at 6 h and 24 h after delivery in the experimental group were less than those in the control group, and the differences were statistically significant (all P<0.05). There were no significant differences between the two groups in the incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution (all P>0.05). (3) Adverse reactions occurred in 2 cases (1.4%, 2/148) in the experimental group and 1 case (0.7%, 1/150) in the control group. There was no significant difference between the two groups (P>0.05). The systolic blood pressure within 2.0 h and diastolic blood pressure within 1.5 h of drug administration in the experimental group were higher than those in the control group, and the differences were statistically significant (P<0.05), but the blood pressure of the two groups were in the normal range. Conclusion: The use of ergometrine injection in CS could reduce the amount of PPH, which is safe and feasible.

Abstract
Radioactive iodine (129I and 131I), produced or released from nuclear-related activities, posed severe effects on both human health and environment. The efficient removal of radioiodine from aqueous medium and vapor phase is of paramount importance for the sustainable development of nuclear energy. Herein, a metal-organic framework (MOF) nanosheet with a positive charge was constructed for the capture of iodine for the first time. The as-synthesized ultrathin nanosheets, with a thickness of 4.4 ± 0.1 nm, showed a record-high iodine adsorption capacity (3704.08 mg g-1) from aqueous solution, which is even higher than that from the vapor phase (3510.05 mg g-1). It can be ascribed to the fully interactions between the extensive accessible active sites on the largely exposed surface of 2D MOF nanosheets and the target pollutants, which also gave rise to fast adsorption kinetics with relative high removal efficiencies in the low concentrations, even in seawater. Moreover, a facile recyclability with fast desorption kinetics can also be achieved for the MOF nanosheets. The excellent iodine removal performance in aqueous solution demonstrated that the electrostatic attraction between MOF nanosheets with a positive charge and the negatively charged triiodide (I3-, the dominant form of iodine in aqueous solution) is the driving force in adsorption, which endows the adsorbents with the characteristics of fast adsorption and desorption kinetics. The adsorption mechanism was systematically verified by the studies of ζ potential, Fourier transform infrared, X-ray photoelectron spectroscopy, and Raman spectra.

Abstract
Two-dimensional (2D) metal-organic framework (MOF) nanosheets, with largely exposed surface area and highly accessible active sites, have emerged as a novel kind of sensing material. Here, a luminescent 2D MOF nanosheet was designed and synthesized by a facile top-down strategy based on a three-dimensional (3D) layered MOF {[Zn(H2L)(H2O)2]·H2O}n (Zn-MOF; H4L = 3,5-bis(3',5'-dicarboxyphenyl)-1H-1,2,4-triazole). With a large π-conjugated system and rigid planar structure, ligand H4L was elaborately selected to construct the bulk Zn-MOF, which can be readily exfoliated into 2D nanosheets, owing to the weak interlayer interactions and easy-to-release H2O molecules in the interspaces of 2D layers. Given the great threat posed to the ecological environment by anti-inflammatory drugs and pesticides, the developed luminescent Zn-MOF nanosheets were utilized to determine these organic pollutants, achieving highly selective and sensitive detection of diclofenac sodium (DCF) and tetramethylthiuram disulfide (TMTD). Compared to the detection limits of 3D Zn-MOF (7.72 ppm for DCF, 6.01 ppm for TMTD), the obviously lower detection limits for 2D Zn-MOF nanosheets toward DCF (0.20 ppm) and TMTD (0.18 ppm) further revealed that the largely exposed surface area with rigid planar structure and ultralarge π-conjugated system greatly accelerated electron transfer, which brought about a vast improvement in response sensitivity. The remarkable quenching performance for DCF and TMTD stems from a combined effect of photoinduced electron transfer and competitive energy absorption. The possible sensing mechanism was systematically investigated by the studies of powder X-ray diffraction, UV-vis, luminescence lifetime, and density functional theory calculations.

Abstract
Objective: To evaluate the nutritional status by the Controlling Nutritional Status (CONUT) score and its association with the long-term prognosis in patients with acute heart failure (AHF). Methods: This prospective monocentric study consecutively enrolled patients admitted to our hospital for AHF from April 2012 to May 2016. Patients were divided into 3 groups based on the CONUT score at admission: normal (0-1), mild malnutrition (2-4) and moderate-severe malnutrition (5-12) groups. Baseline information was obtained and recorded within 24 hours after admission. All patients were followed up every 3 months by outpatient visit or telephone call until March 2019. The primary endpoint was all-cause mortality. The Kaplan-Meier survival curves and log-rank test were used to compare all-cause mortality between groups. Variables showing statistical significance in the univariate analysis were incorporated into multivariate Cox regression model to analyze the independent risk factors for all-cause mortality after discharge. Results: A total of 396 patients were enrolled in this study, including 114 patients with normal nutritional status, 200 patients with mild malnutrition and 82 patients with moderate-severe malnutrition. One hundred and fifty-eight patients died during a median follow-up of 34 (18, 46) months. The mortality was 32.4% (37/114), 39% (78/200) and 52.4% (43/82) in normal, mild malnutrition and moderate-severe malnutrition groups, respectively. The mortality was significantly higher in the moderate-severe malnutrition group than in normal nutrition group (P<0.05). However, there was no significant difference in mortality between normal and mild malnutrition group as well as between mild and moderate-severe malnutrition group (both P>0.05). Kaplan-Meier curves indicated that patients with high CONUT score group was at higher risk of all-cause mortality compared with those with low CONUT score (P=0.002). Cox proportional hazard analyses showed that the risk of all-cause mortality of moderate-severe malnutrition group was significantly higher than that of normal nutrition group (HR =1.648, 95%CI 1.021-2.660, P=0.041). Conclusions: The CONUT score of patients with AHF at admission is associated with the long-term prognosis. High CONUT score is an independent risk factor for all-cause mortality in AHF patients after discharge.

Abstract
Nighteen people at a restaurant experienced dizziness headaches and other discomforts in six days. According to the description method, the time and location distribution were found to be concentrated. A second Investigation was conducted at the same time as the onset of the case, the test found that the carbon monoxide concentration of second floor up to 539 mg/m(3). The on-site testing found that when 2 steam generator in snack room on the first floor turned on, the carbon monoxide concentration on the top of elevator on the second floor was 1225.0 mg/m(3). After the accident, the restaurant replaced a steam generator, the carbon monoxide concentration on the top of the new and old steam generator were 350 mg/m(3) and >1 000 mg/m(3), respectively. After the steam generators were fitted with exhaust smoke pipe and exhasust hood, the carbon monoxide concentrations of on the top of the vegetable transfer elevator and the room on the second floor were both 0.4 mg/m(3), and there were no cases of recurrence. It was determined that this was a carbon monoxide poisoning incident caused by a high concentration of carbon monoxide emitted by the steam generators, which spread to the second floor of the private room through the vegetable transfer elevator.

Abstract
Objective: To investigate the etiology of necrotizing pneumonia (NP) in children and the clinical characteristics of NP caused by different pathogens in China. Methods: A retrospective, case-control study was performed in children with NP who were admitted to 13 hospitals in China from January 2008 to December 2019. The demographic and clinical information, laboratory data, etiological and radiological findings were analyzed. The data were divided into three groups based on the following years: 2008-2011, 2012-2015 and 2016-2019, and the distribution characteristics of the pathogens in different period were compared. Meanwhile, the pathogens of pediatric NP in the southern and northern China were compared. And the clinical characteristics of the Mycoplasma pneumoniae (MP) NP and the bacterial NP were also compared. T-test or Mann-Whitney nonparametric test was used for comparison of numerical variables, and χ2 test was used for categorical variables. Results: A total of 494 children with NP were enrolled, the median ages were 4.7 (0.1-15.3) years, including 272 boys and 222 girls. Among these patients, pathogens were identified in 347 cases and the pathogen was unclear in the remaining 147 cases. The main pathogens were MP (238 cases), Streptococcus pneumoniae (SP) (61 cases), Staphylococcus aureus (SA) (51 cases), Pseudomonas aeruginosa (13 cases), Haemophilus influenzae (10 cases), adenovirus (10 cases), and influenza virus A (7 cases), respectively. MP was the most common pathogen in all three periods and the proportion increased yearly. The proportion of MP in 2016-2019 was significantly higher than that in 2012-2015 (52.1% (197/378) vs. 36.8% (32/87), χ2=6.654, P=0.010), while there was no significant difference in the proportion of MP in 2012-2015 and that in 2008-2011 (36.8% (32/87) vs. 31.0% (9/29), χ²=0.314, P=0.575).Regarding the regional distribution, 342 cases were in the southern China and 152 in the northern China. Also, MP was the most common pathogen in both regions, but the proportion of MP was higher and the proportion of SP was lower in the north than those in the south (60.5% (92/152) vs. 42.7% (146/342), χ2=13.409, P<0.010; 7.9% (12/152) vs. 14.3% (49/342), χ2=4.023, P=0.045). Comparing the clinical characteristics of different pathogens, we found that fever and cough were the common symptoms in both single MP and single bacterial groups, but chest pain was more common (17.0% (34/200) vs. 6.1% (6/98), χ2=6.697, P=0.010) while shortness of breath and wheezing were less common in MP group (16.0% (32/200) vs. 60.2% (59/98), χ2=60.688, P<0.01; 4.5% (9/200) vs. 21.4% (21/98), χ2=20.819, P<0.01, respectively). The white blood cell count, C-reactive protein and procalcitonin in the bacterial group were significantly higher than those in the MP group (14.7 (1.0-67.1)×109/L vs. 10.5 (2.5-32.2)×109/L, 122.5 (0.5-277.3) mg/L vs. 51.4 (0.5-200.0) g/L, 2.13 (0.05-100.00) μg/L vs. 0.24 (0.01-18.85) μg/L, Z=-3.719, -5.901 and -7.765, all P<0.01). Conclusions: The prevalence of pediatric NP in China shows an increasing trend during the past years. MP, SP and SA are the main pathogens of NP, and the most common clinical symptoms are fever and cough. The WBC count, C-reactive protein and procalcitonin in bacterial NP are significantly higher than those caused by MP.

Abstract
We theoretically investigate the linear susceptibility and propagation of light in a three-dimensional (3-D) Rydberg gas under conditions of electromagnetically induced transparency. Rydberg atoms with two relevant S states are coupled via exchange interactions. When the gas is initially prepared in an entangled spin-wave state, this coupling induces a strong, nonlocal susceptibility whereby the photon field at one point of the medium acts as a source at a distant position. The nonlocal propagation occurs not only in the propagation direction but also in the paraxial direction. We discuss the absorption features and numerically simulate the 3-D propagation of probe laser light. Combined with the long-range exchange interaction, we show that the 3-D Rydberg gas is an ideal medium for studying nonlocal wave phenomena, in which the strength, range, and sign of the nonlocal interaction kernel can be widely tuned.

Abstract
Objective: To establish the nutrition literacy core items for Chinese lactating women. Methods: The framework system and preliminary items of nutrition literacy were established through literature review and experts consultation. E-Delphi method was used to determine the nutrition literacy items. 11 experts in the field of maternal and child nutrition, obstetrics and gynecology, health education and nutrition and diseases were invited to score the importance of each nutrition literacy item via Email. The judgment basis and familiarity of experts towards the items, active coefficient, authority coefficient and harmony coefficient were evaluated and analyzed to generate the final list of nutrition literacy items. Results: The active coefficients of consultation in two rounds were 81.8% (9/11) and 87.5% (8/9). The authority coefficients were (0.86±0.11) and (0.85±0.06). The average scores of importance were (4.03±1.24) and (4.64±0.50)and the harmony coefficients were 0.556 (χ²=163.42, P<0.001) and 0.40 (χ²=64.41, P<0.001). After the second round of consultation, all selected items met the inclusion criteria. We identified the final list of nutrition literacy items consisting of 3 scales (basic knowledge and concept, lifestyles and dietary behaviors, and basic skills), 10 subscales (basic nutrition concept, food and nutrition knowledge, feeding knowledge, lifestyles, dietary behaviors, feeding behaviors, weight management, complementary food production, acquisition, understanding and application of nutrition information, judgement of nutrition information, and nutrition decision making) with 24 items in total. Conclusions: The framework system and core items of nutrition literacy were established for Chinese lactating women based on E-Delphi method. The experts involved in the consultation process presented a performance with good representativeness, enthusiasm and authority. All experts' opinions are coordinated and unified, which could satisfy the demand of developing nutrition literacy core items for target population.

Abstract
Nutrition literacy is one of essential components of health literacy. A relatively mature health literacy evaluation system has been established in China so far. However, the studies on nutrition literacy evaluation are still limited, especially for specific population, such as children, adolescents, older people, and maternal. The present study introduces the concept of nutrition literacy, and summarizes the evaluation tools of nutrition literacy for both general population and special population (i.e., children, adolescents, older people, and maternal) in China and foreign countries, and their dimension, reliability, validity and applicable scope. This study aim to provide evidence for the development of nutrition literacy evaluation tools for different population according to the current problem of nutrition in China.

Abstract
Objective: To investigate the prevalence, awareness, treatment and control of hypertension in adult residents in Jiangsu province and provide evidence for the prevention and control of hypertension. Methods: A population-based cardiovascular disease screening project was conducted during 2015-2018 in Jiangsu, a total of 95 348 community-dwelling adults aged 35-75 years from 6 project areas were included in the study. The prevalence rate of hypertension and rates of awareness, treatment and control of hypertension in the adults with different characteristics were analyzed. Multilevel model was applied to identify the influencing factors. Results: Among 95 348 adults surveyed, 54 407 were hypertensive, the standardized prevalence rate was 48.1%. The prevalence rate was significantly higher in males than in females (62.1% vs. 54.0%, P<0.05). Among the hypertension patients, the rates of awareness, treatment and control of hypertension were 56.6%, 45.3% and 12.0% (standardized rates: 52.2%, 41.0% and 11.2%), respectively, and all the rates were positively associated with age (all P<0.05). Multilevel model analysis showed that those who were males, at older age, lived in rural area, suffered from diabetes, had frequent alcohol drinking and those who were overweight/obese had higher risk for hypertension (all P<0.05). Among people with hypertension, those who had younger age, lower education level, lower household income level and those who had frequent alcohol drinking had lower awareness, treatment and control rates of hypertension (all P<0.05). Conclusions: The prevalence rate of hypertension was high, but related awareness, treatment and control rates were low in adult residents in Jiangsu province. Comprehensive measures should be taken to improve awareness, treatment and control of hypertension in whole population, especially in young adults, and those with low education or income levels.

Abstract
Objective: To compare the characteristics of Mycoplasma pneumoniae necrotizing pneumonia (MPNP) and bacterial necrotizing pneumonia (BNP), and explore the biomarkers for differentiation of MPNP from BNP. Methods: A retrospective, observational study of 52 necrotizing pneumonia (NP) cases who were hospitalized in our hospital from January 2008 to December 2017 was conducted. According to the pathogen causing NP, patients were divided into two groups, BNP and MPNP, and the clinical manifestations, laboratory data, imaging findings, hospital course and prognosis between these groups were analyzed. Results: This study enrolled 19 boys and 33 girls, and the median ages of patients were 4.4 (0.1-13.8) years old. Of the totally of 52 NP patients, 19 were in the BNP group (9 boys and 10 girls), 33 were in the MPNP group (10 boys and 23 girls). The mean age of MPNP patients was much older than that of BNP patients (5.2 (2.3-13.2) years vs. 1.8 (0.1-13.8) years, Z=-0.128, P<0.01). The number of patients with tachypnea and pleural effusion septation were significantly higher in BNP patients than those in MPNP patients (15 cases vs. 4 cases, χ(2)=23.222, P<0.01; 14 cases vs. 1 case, χ(2)=29.326, P<0.01), which more needed to oxygentherapy (18 cases vs. 12 cases, χ(2)=16.833, P<0.01) and undergo chest drainage (9 cases vs. 4 cases, χ(2)=5.829, P=0.022); while the number of patients required bronchoalveolar lavage was higher in MPNP patients than that in BNP patients (5 cases vs. 32 cases, χ(2)=29.326, P<0.01). The values of white blood cell (WBC) (23.2 (5.2-67.1)×10(9)/L vs. 9.7 (6.3-18.7)×10(9)/L, Z=-4.855, P<0.01), procalcitonin (PCT) (3.69 (0.23-90.15) mg/L vs. 0.28 (0.02-1.44) mg/L, Z=-3.207, P=0.001), C reactive protein (CRP) (160 (94-220) mg/L vs. 90 (5-134) mg/L, Z=-4.337, P<0.01), interleukin (IL)-10 (11.7 (4.2-401.5) ng/L vs. 4.8 (2.0-23.4) ng/L, Z=-2.278, P=0.023), pleural fluid cell count (5 200 (120-50 000)×10(6)/L vs. 790 (68-6 920)×10(6)/L, Z=-3.125, P=0.002), pleural fluid lactic dehydrogenase (LDH) (3 990 (589-29 382) U/L vs. 2 211 (673-3 993) U/L, Z=-2.488, P=0.013) in BNP group were significantly higher than those in MPNP group; while the values of pleural fluid glucose(0.43 (0.03-18.00) mmol/L vs. 5.95 (4.27-7.87) mmol/L, Z=-2.795, P=0.005), serum tumor necrosis factor (TNF)-α (2.3 (1.0-2.8) ng/L vs. 2.6 (1.3-109.2) ng/L, Z=-2.113, P=0.035) and interferon (IFN)-γ (4.8 (2.6-7.7) ng/L vs. 11.9 (2.9-154.6) ng/L, Z=-2.455, P=0.014) were lower in BNP group than those in MPNP group. Meanwhile, the mean time from the onset of symptoms to the discovery of necrotic lesions was longer in MPNP group than that in BNP group ((20.6±6.4) days vs. (14.6±6.2) days, t=3.029, P=0.004). After treatments, all patients were discharged without death, WBC and PCT recovered more quickly in MPNP group than those in BNP group (12 (0-24) days vs. 0 (0-23) days, Z=-4.484, P<0.01; 10 (5-15) days vs. 0 (0-23) days, Z=-3.244, P=0.001). As to prognosis, 34 cases were followed up, and the results showed that patients recovered without surgical intervention, and chest lesions were resolved within 3.0 (1.0-8.0) months, and the time to necrosis disappearance was similar in the BNP group and MPNP greup (3.0 (1.0-8.0) months vs. 3.0 (1.0-8.0) months, Z=-0.128, P=0.001). In receiver operator characteristic curve analysis, the cut-off values for the age, WBC, CRP, PCT, pleural fluid cell count and pleural fluid glucose were set at 2.4 years of age, 17.2×10(9)/L, 157 mg/L, 1.505 mg/L, 2 630×10(6)/L and 3.73 mmol/L, respectively. Conclusions: NP is found to be severe and prolonged, yet, reversible through proper therapy, such as rational antibiotics application. The age, WBC, CRP, PCT, pleural fluid cell count and pleural fluid glucose could be used as biomarkers to differentiate MPNP from BNP in children.

Abstract
The forced migration of diblock copolymers (ANABNB) in periodically patterned slits was investigated by using Langevin dynamics simulation. The lower surface of the slit consists of stripe α and stripe β distributed in alternating sequence, while the upper one is formed only by stripe β. The interaction between block A and stripe α is strongly attractive, while all other interactions are purely repulsive. Simulation results show that the migration of the diblock copolymer is remarkably dependent on the driving force and there is a transition region at moderate driving force. The transition driving force ft, where the transition region occurs, decreases monotonously with increasing length of block B (NB) but is independent of the polymer length and the periodic length of the slit, which is interpreted from the free energy landscape of diblock copolymer migration. The results also show that periodic slits could be used to separate diblock polymers with different NB by tuning the external driving force.

Abstract
Objective: To explore the expression and distribution of programmed death receptor 1 (PD-1) and T-cell immunoglobulin mucin 3 (TIM-3) in breast cancer microenvironment and analyze the their correlation with the clinicopathological features. Methods: The specimens of tumor tissue and adjacent tissues from 30 patients with infiltrative breast cancer who were diagnosed as breast cancer from June 2016 to May 2017 in The First Hospital of Jiaxing were collected, and the specimen were divided into two parts along the center. After embedding and cryosectioning, the expression and distribution of PD-1 and TIM-3 protein in tumor tissues were observed by immunofluorescence staining. Another part of the specimen was cut and digested, and non-continuous density gradient centrifugation was used to extract tumor-infiltrating lymphocytes (TILs), real-time quantitative PCR (qRT-PCR) was used to detect the mRNA expression of PD-1 and TIM-3 in TILs. Meanwhile, the protein expression was determined by Western blotting. The relationship between the expression of PD-1 and TIM-3 and pathological parameters of breast cancer was analyzed with correlation analysis. Results: Immunofluorescence results showed that more PD-1 and TIM-3 positive cells were observed in the tumor tissues compared with the tumor-adjacent tissues. The qRT-PCR showed that the expression of PD-1 and TIM-3 mRNA in TILs were both significantly higher than those in paracancerous tissues (3.09±0.38 vs 1.26±0.23, 3.42±0.31 vs 1.57±0.29, t=4.16, 4.37, both P<0.05). At the protein level, the expression of PD-1 and TIM-3 in tumor tissue lymphocytes(0.66±0.08, 0.80±0.11) was significantly higher than those in cancerous tissues(0.10±0.01, 0.26±0.02) (t=6.79, 4.57, both P<0.05). There were significant differences in the expression of PD-1, TIM-3 mRNA in the TILs between the different tumor histological grades, tumor sizes, lymph node metastasis (t=2.22-2.99, all P<0.05). Correlation analysis showed that there was a significant positive correlation between the expression of PD-1 and TIM-3 in tumor tissues (r=0.616, P<0.01). Conclusions: In the breast cancer microenvironment, PD-1, TIM-3-mediated signaling pathway plays an important role in the occurrence and development of breast cancer, it provides a new basis for the combination therapy of breast cancer.

Abstract
Objective: To investigate the predominant genotypes and epidemiological characteristics of human adenovirus (HAdV) in pediatric community-acquired pneumonia (CAP) in China. Methods: This was a repeated cross sectional study. Between November 2014 and November 2016, nasopharyngeal aspirates (NPAs) or throat swabs from each hospitalized pediatric patients diagnosed as CAP in 12 hospitals in Northern and Southern China were collected. Respiratory specimens were screened for 18 respiratory viruses including HAdV by using Luminex xTAG RVP Fast V2 multiplex Assay. Typing of HAdV and analysis for the epidemiological characteristic of HAdV were performed. Results: (1) A total of 2 723 hospitalized pediatric patients with CAP were enrolled in this study and 156 (5.7%, 156/2 723) respiratory specimens were positive for HAdV, and 74 (6.6%, 74/1 128) and 82 (5.1%, 82/1 595) were in Northern and Southern China, respectively. There was no significant difference in the positive detection rate between the Northern and Southern China. (2) In Northern China, the HAdV positive rate of children at the age of <6 months, 6 months-<1 years, 1-<3 years, 3-<5 years and ≥5 years was 5.9%(6/101), 6.7%(7/104), 10.3%(34/331), 4.1%(11/266) and 4.9%(16/326), respectively, and the incidence of HAdV infection peaked in children aged 1-3 years (χ(2)=11.511, P=0.021). While in Southern China the HAdV positive rate of children at the age of <6 months, 6 months-<1 years, 1-<3 years, 3-<5 years and ≥5 years was 2.2% (7/312), 4.6% (12/259), 6.3% (31/494), 7.3% (18/245) and 4.9%(14/285), respectively. There was no significant difference in the positive detection rate among age groups. (3) In 2015, the highest detection rate of HAdV in northern China was 12.5% (25/200) in winter, and in Southern China was 6.7% (35/525) in spring and 5.3% (19/357) in summer. (4) In 108 cases of HAdV positive specimens typing was done and 80 in cases classification was successfully performed.Totally 7 genotypes of HAdV, including HAdV-3 (n=32), HAdV-7 (n=9), HAdV-1 (n=12), HAdV-2 (n=15), HAdV-5 (n=10), HAdV-6 (n=1) and HAdV-4 (n=1), were detected. The predominant HAdV genotypes were HAdV-3 (30.8%, 8/26) and HAdV-7 (26.9%, 7/26) in Northern China, while HAdV-3 (44.4%, 24/54) and HAdV-2 (22.2%, 12/54) were the most prevalent genotypes in Southern China. Conclusions: HAdV is an important viral pathogen in pediatric CAP. The predominant HAdV genotypes and peak seasons of HAdV infections were different between Northern and Southern China. The predominant HAdV genotypes were HAdV-3 and HAdV-7 in Northern China, while HAdV-3 and HAdV-2 in Southern China. The peak season of HAdV infections was winter in Northern China. However, HAdV infections are more common in spring and summer in Southern China.

Abstract
We sought to investigate the strength of two multi-strand tendon repair configurations in a chicken model. Fifty-six chicken flexor tendons were repaired with one to two different four-strand configurations: 1) a four-strand repair consisting of a two-strand core modified Kessler suture with a circle loop repair and 2) a four-strand core Kessler suture repair with three separate peripheral suture points. The strength of the repaired tendons were measured 2, 3 and 4 weeks after the surgical repair and were analyzed statistically. The strength of the two repair methods was not statistically different 2 weeks after surgery. The tendons repaired with the four-strand core Kessler suture repair and three separate peripheral suture points were significantly stronger than those repaired with a two-strand core modified Kessler suture and a circle loop repair at 3 weeks (P = 0.033) and 4 weeks (P = 0.039). The four-strand repair with three separate peripheral suture points had greater strength than a two-strand repair with one circle loop suture based on an in vivo chicken flexor tendon model.

Abstract
Background Clinical study has demonstrated that the traditional Chinese medicine Qiliqiangxin (QLQX) has protective effects on heart failure. Phenylephrine (PE) is an important inducing factor for cardiac hypertrophy and our previous studies have showed that QLQX attenuates PE-induced cardiac hypertrophy. Besides, QLQX protects against cardiac remodeling after myocardial infarction via activating PPARγ. However, whether QLQX prevents PE-induced cardiac hypertrophy through PPARγ and its coactivator PGC-1α is still unknown. Methods The effects of QLQX were investigated based on PE induced cardiac hypertrophy mouse models. Echocardiography and hematoxylin-eosin (HE) staining were used to determine cardiac function and cross-sectional area, respectively. Quantitative real time PCR (qRT-PCR) was used to determine ANP and BNP expressions. Based on primary neonatal rat ventricular cardiomyocytes (NRVMs) treated with PE, the cell size and expressions of ANP and BNP were determined by immunofluorescent staining and qRT-PCR, respectively. In addition, western blot was used to determine PPARγ and PGC-1α expressions. Results In present study, we confirmed that QLQX could significantly attenuate cardiac hypertrophy in mice treated with PE. Then we showed that PPARγ and PGC-1α were downregulated in PE-induced cardiac hypertrophy, and QLQX could block the decrease of PPARγ and PGC-1α both in vitro and in vivo. Importantly, we found that PPARγ inhibitors or PGC-1α siRNAs eliminated the protective effects of QLQX on PE-induced cardiac hypertrophy. Conclusions Our study suggested that QLQX prevents from PE-induced cardiac hypertrophy by activating PPARγ and its coactivator PGC-1α.

Abstract
The development of multidrug resistance (MDR) is a crucial cause of therapy failure in gastric cancer, which results in disease recurrence and metastasis. Long non-coding RNAs (lncRNAs) have been proven to be critical in carcinogenesis and metastasis of gastric cancer. However, little is known about the roles of ANRIL (antisense non-coding RNA in the INK4 locus) in gastric cancer MDR. The aim of our study is to identify the biological function of ANRIL in gastric cancer MDR. In our results, ANRIL was highly expressed in gastric cancer tissues of cisplatin-resistant and 5-fluorouracil (5-FU)-resistant patients, and the same upregulation trends were observed in cisplatin-resistant cells (BGC823/DDP) and 5-FU-resistant cells (BGC823/5-FU). In addition, BGC823/DDP and BGC823/5-FU cells transfected with ANRIL siRNA and treated with cisplatin or 5-FU, respectively, exhibited significant lower survival rate, decreased invasion capability, and high percentage of apoptotic tumor cells. The influence of ANRIL knockdown on MDR was assessed by measuring IC50 of BGC823/DDP and BGC823/5-FU cells to cisplatin and 5-FU, the result showed that silencing ANRIL decreased the IC50 values in gastric cancer cells. Moreover, qRT-PCR and western blotting revealed that ANRIL knockdown decreased the expression of MDR1 and MRP1, both of which are MDR related genes; regression analysis showed that the expression of ANRIL positively correlated with the expression of MDR1 and MRP1, resprectively In summary, knockdown of lncRNA ANRIL in gastric cancer cells inhibits the development of MDR, suggesting an efficacious target for reversing MDR in gastric cancer therapy.

Abstract
AIMS Our aim is to identify important lncRNAs and mRNAs which may play a key role in contributing to pathogenesis of gastric cancer. METHODS Different LncRNAs and mRNAs are identified by microarray in gastric cancer tissue and corresponding normal tissues. The function and relationship of different LncRNAs and mRNAs is performed by GO analysis and Pathway analysis and made code-non-code network (CNC) by Pearson correlation coefficients (PCC). Then mRNA-miRNA relationship is predicted through mRNA-miRNA relationship software (http://www.targetscan.org). Lastly, mRNA-miRNA-LncRNA network is established for further research. RESULTS The expression profiles of 3732 lncRNAs showed different expression (fold change (FC)≥2.0, p<0.05) in gastric cancer tissue and normal tissue and expression profiles of 3994 mRNAs also showed different expression (FC≥2.0, p<0.05) in gastric cancer and corresponding normal tissue. CONCLUSION The expression of TM4SF5, CTD-2354A18.1 and miR-4697-3P is in balance at physiological conditions, however, the balance is disrupted by some situations, which may contribute to gastric cancer. GO analysis and Pathway analysis also showed TM4SF5 played an important role in proliferation, differentiation and apoptosis. Therefore, TM4SF5-miR-4697-3P- CTD-2354A18.1 may play a key role in the pathogenesis of gastric cancer (Tab. 2, Fig. 4, Ref. 30).

Abstract
OBJECTIVE Growth differentiation factor-15 (GDF-15) has been identified as a strong biomarker of cardiovascular diseases; however, no evidence are available concerning the relationship of GDF-15 and atrial fibrosis in patients with atrial fibrillation (AF) and rheumatic heart disease (RHD). METHODS Twenty patients with rheumatic heart disease were divided into two groups, 10 cases with AF and 10 cases with sinus rhythm (SR). Clinical data and blood samples were collected; left atrial appendage was taken by the surgeon in the process of valve replacement. Masson stained sections and mRNA levels of cardiac fibrosis biomarkers were used to determine the level of cardiac fibrosis, the expression level of GDF-15 was evaluated via immunohistochemistry, enzyme-linked immunosorbent assay (ELISA) and real-time polymerase chain reaction (PCR). RESULTS Compared with SR group, more collagen deposited in the atrial tissue of AF group. The distribution of GDF-15 in the AF group was significantly higher than SR group (P<0.05). In addition, plasma GDF-15 level and mRNA level of GDF-15 in atrial tissue of AF showed the same trend as the result of immunohistochemistry. After linear correlation analysis, the expression level of GDF-15 was found to be positively related to the degree of cardiac fibrosis. CONCLUSION GDF-15 might involve in the development and maintenance of atrial fibrosis in patients with atrial fibrillation and rheumatic heart disease, and GDF-15 could be used as a novel biomarker to evaluate myocardial fibrosis in the future.

Abstract
Adhesion formation after digital flexor tendon injury greatly affects gliding function of the tendon, which is a major clinical complication after hand surgery. Transforming growth factor beta 1 (TGF-β1) has a critical role in adhesion formation during tendon healing. Persistent regulation of TGF-β1 through application of microRNA (miRNA) specifically inhibiting the function of TGF-β1 (TGF-β1-miRNA) holds promise for treatment of such a complication. Adeno-associated virus (AAV) was used to transfer TGF-β1-miRNA to the chicken digital flexor tendons, which had been injured and surgically repaired. Four doses of AAV2-TGF-β1-miRNA (2 × 10¹¹, 2 × 10¹⁰, 2 × 10⁹ and 2 × 10⁸ vector genomes (vg)) were used to determine the transfection efficiency. At postoperative 3 weeks, we found a positive correlation between the administered AAV2-TGF-β1-miRNA doses and transfection efficiency. The transfection rate ranged from 10% to 77% as the doses increased. Production of TGF-β1 protein in the tendons decreased on increasing vector dosage. When 2 × 10¹¹ and 2 × 10¹⁰) vg were injected into the tendon, gliding excursion of the repaired tendon and work of flexion of chicken toes were significantly increased and adhesion score decreased 6 and 8 weeks later, indicating the improvement of tendon gliding and decreases in adhesion formations. However, the ultimate strength of the tendons transfected at the dose of 2 × 10¹⁰ vg was 12-24% lower than that of the control tendons. The results of this study demonstrate that application of TGF-β1-miRNA had a mixed impact on tendon healing: adhesion around the tendon is reduced but strength of the tendon healing is adversely affected. Future studies should aim at maintaining the beneficial effects of reducing tendon adhesions, while eliminating the adverse effects of decreasing the healing strength.

Abstract
Settlement of cyanobacterial bloom biomass (CBB) into sediments in eutrophic lakes often induced the occurrence of black water agglomerate and then water quality deterioration. This study investigated the effect of sediment microbial fuel cell (SMFC) on CBB removal in sediments and related water pollution. Sediment bulking and subsequent black water from decomposition of settled CBB happened without SMFC, but were not observed over 100-day experiments with SMFC employment. While CBB in sediments improved power production from SMFC, the removal efficiency of organic matters in CBB-amended sediments with SMFC was significantly lower than that without SMFC. Pyrosequencing analysis showed higher abundances of the fermentative Clostridium and acetoclastic methanogen in CBB-amended bulk sediments without SMFC than with SMFC at the end of experiments. Obviously, SMFC operation changed the microbial community in CBB-amended sediments, and delayed the CBB degradation against sediment bulking. Thus, SMFC could be potentially applied as pollution prevention in CBB-settled and sensitive zones in shallow lakes.

Abstract
Powdery resistance putatively derived from Thinopyrum intermedium in the wheat line L962 is controlled by a single dominant gene designated PmL962 and mapped to chromosome arm 2BS. Powdery mildew, caused by Blumeria graminis f. sp. tritici (Bgt), is a destructive disease affecting the production of wheat (Triticum aestivum). Powdery mildew resistance was putatively transferred from Thinopyrum intermedium to the common wheat line L962, which conferred resistance to multiple Chinese Bgt isolates. Genetic analysis of the powdery mildew response was conducted by crossing the resistant line L962 with the susceptible line L983. Disease assessments of the F1, F2, and F2:3 populations from the cross L983/L962 indicated that resistance was controlled by a single dominant gene. A total of 373 F2:3 lines and 781 pairs of genomic simple sequence repeat (SSR) primers were employed to determine the chromosomal location of the resistance gene. The gene was linked to four publicly available and recently developed wheat genomic SSR markers and seven EST-STS markers. The resistance gene was mapped to chromosome arm 2BS based on the locations of the linked markers. Pedigree, molecular marker and resistance response data indicated that the powdery mildew resistance gene in L962 is novel. It was temporarily designated PmL962. It is flanked by Xwmc314 and BE443737at genetic distances of 2.09 and 3.74 cM, respectively, and located in a 20.77 cM interval that is co-linear with a 269.4 kb genomic region on chromosome 5 in Brachypodium distachyon and a 223.5 kb genomic region on rice (Oryza sativa) chromosome 4. The markers that are closely linked to this gene have potential applications in marker-assisted breeding.

Abstract
Acrylonitrile (ACN) is a widely used chemical in the production of plastics, resins, nitriles, acrylic fibers, and synthetic rubber. Previous epidemiological investigations and animal studies have confirmed that ACN affects the lymphocytes and spleen. However, the immune toxicity mechanism is unknown. Lipid rafts are cell membrane structures that are rich in cholesterol and involved in cell signal transduction. The B cell lymophoma-10 (Bcl10) protein is a joint protein that is important in lymphocyte development and signal pathways. This study was conducted to examine the in vitro effects of ACN. We separated lipid rafts, and analyzed Bcl10 protein and caveolin. Western blotting was used to detect mitogen-activated protein kinase (MAPK) and phosphorylated MAPK levels. The results indicated that with increasing ACN concentration, the total amount of Bcl10 remained stable, but was concentrated mainly in part 4 to part 11 in electrophoretic band district which is high density in gradient centrifugation. Caveolin-1 was evaluated as a lipid raft marker protein; caveolin-1 content and position were relatively unchanged. Western blotting showed that in a certain range, MAPK protein was secreted at a higher level. At some ACN exposure levels, MAPK protein secretion was significantly decreased compared to the control group (P < 0.05). These results indicate that ACN can cause immune toxicity by damaging lipid raft structures, causing Bcl10 protein and lipid raft separation and restraining Ras-Raf-MAPK-extracellular signal-regulated kinase signaling pathways.

Abstract
Using first-principles calculation based on density functional theory, diffusion of Mg atom into α- and β-Sn was investigated. The diffusion barriers are 0.395 and 0.435 eV for an isolated Mg atom in the α- and β-Sn, respectively. However, the diffusion barriers of the Mg atom decrease in the α-Sn, whereas they increase in the β-Sn, when an additional Mg atom was inserted near the original diffusing Mg atom, which is mainly due to strong binding of Mg-Mg atoms in the β-Sn. Therefore, it is better to use the α-Sn, rather than the β-Sn, as an anode material for Mg ion batteries.

Abstract
Effects of iron oxide amendment into freshwater sediments on performance of sediment microbial fuel cell (SMFC) were investigated. It was found that amending amorphous bulk ferric oxyhydroxide, and crystalline goethite and magnetite did not affect SMFC operation. However, amendment of the mixed solution including soluble ferric citrate and colloidal iron oxyhydroxide, stably improved SMFC performance with voltage outputs up to threefolds higher than those without amendment. The enhanced voltage production corresponded to lower anode potential, but was not related to organic matter removal in sediments. Further experiments demonstrated that colloidal iron oxyhydroxide instead of soluble ferric iron played an important role in voltage production through maintaining high-concentration ferrous iron in pore water of sediments as electron shuttle and for chemical oxidation on the anode. Thus, colloidal iron oxyhydroxide amendment was a promising strategy to improve power production from SMFC employed in sediments especially with low content of organic matters.

Abstract
OBJECTIVE To investigate the role of Th17 cells of synovial fluid (SF)in the pathogenesis of rheumatoid arthritis (RA). METHODS RA patients with knee synovial fluid (n = 15) and healthy volunteers (n = 15) were enrolled. The amounts of Th17 cells in peripheral blood and SF were measured by flow cytometry. Since there was no SF in healthy control, only the amounts of Th17 cells in peripheral blood were measured. The correlation between the amounts of SF Th17 cells and clinical inflammatory parameters was evaluated. Retinoic acid-related orphan receptor gammat (RORgammat), interleukin-17 (IL-17) gene expression in lymphocytes were assessed by real-time PCR. RESULTS The percentages of Th17 cells in SF from RA patients (1.89 +/- 0.88)% were significantly higher than that in paired PB from RA patients (1.03 +/- 0.57)% and that in PB from healthy controls (0.35 +/- 0.18)%; (2) The frequency of Th17 cells in SF from RA patients correlated positively with serum CRP (r = 0.519, P = 0.047); (3) The mRNA levels of RORgammat and IL-17 were increased in SF lymphocyte population from RA patients compared to paired PB from RA patients and healthy controls (P < 0.01). CONCLUSION Increases of Th17 cells in synovial fluid of patients with RA patients might attribute to the difference between local joint inflammation and systemic inflammation, and participates in joint damage.

Abstract
OBJECTIVE To observe the effect of acupuncture of "Shenmai" (BL 62) and "Zhaohai" (KI 6), "Shenmen" (HT 7), etc. on the expression of hypothalamic gamma-aminobutyric acid (GABA) and GABA(A) receptor (GABA(A)R) proteins in experimental insomnia rats so as to explore its mechanism underlying improving sleeping. METHODS Seventy Wistar rats were randomly divided into normal control, model, "Sanyinjiao" (SP6), "Neiguan" (PC 6), "Zusanli" (ST 36), "Shenmen" (HT7), and "Shenmai" (BL 62)-Zhaohai (KI 6, BL 62-KI 6) groups, with 10 rats in each group. Insomnia model was established by intraperitoneal injection of chlorophenylalanine solution (PCPA, 1 mL/100 g). An acupuncture needle was inserted into each of the bilateral HT 7, PC 6, SP 6, ST 36 and BL 62-KI 6 respectively and manipulated for about 1 min, once daily for 7 days. Hypothamic GABA and GABA(A)R protein expressions were detected by immunohistochemistry. The animals' physical ability was evaluated by using pole-climbing test in a water tank. RESULTS In comparison with the normal control group, the numbers of hypothalamic GABA immunoreaction (IR)- and GABA(A)R IR-positive neurons and the pole-climbing time were reduced significantly in the model group (P < 0.05). While in comparison with the model group, the numbers of hypothalamic GABA IR-positive neurons and those of hypothalamic GABA(A)R IR-positive neurons in the HT 7, PC 6, SP 6, ST 36 and BL 62-KI 6 groups, as well as the pole-climbing duration in the SP 6, ST 36 and BL 62-KI 6 groups were increased considerably (P < 0.05, P < 0.01). The effects of HT 7 and BL 62-KI 6 groups were significantly superior to those of PC 6, ST 36 and SP 6 groups in up-regulating GABA and GABA(A)R expression, and the effect of BL 62-KI 6 group was remarkably better than those of HT 7, PC 6, SP 6 and ST 36 groups in lengthening the pole-climbing time (P < 0.05). CONCLUSION Acupuncture can effectively suppress insomnia induced down-regulation of hypothalamic GABA and GABA(A)R in rats and lengthen pole-climbing time, which may contribute to its effect in relieving insomnia.

Abstract
Increases in the resistance to tendon during movement may lead to rupture or gapping of the repaired tendon. The relative contribution of these factors-tissue oedema, tendon oedema, and the intact A2 pulley-to resistance to tendon gliding is unclear. In in vitro chicken models, we created oedema in subcutaneous tissue or tendon. The work of digital flexion (WOF) increased significantly after creation of oedema in those tissues. WOF decreased significantly after division of the A2 pulley. Preservation of the integrity of the A2 pulley significantly increased WOF at post-operative weeks 1 and 2 in the in vivo chicken model; increases in WOF were greater than those due to the presence of oedematous subcutaneous tissue. Pulley division at the time of surgery reduced WOF more drastically than the removal of volar subcutaneous tissue. Presence of an intact A2 pulley adds greater resistance to the movement of the repaired flexor tendon than volar oedematous subcutaneous tissue.
