Abstract
OBJECTIVE To assess the total factor productivity (TFP) of schistosomiasis control programs in Jiangsu Province, so as to provide insights into sustainable schistosomiasis control. METHODS The data envelopment analysis-Malmquist index method was employed to analyze the human resources and financial investments in schistosomiasis control programs from health sectors in each schistosomiasis-endemic city of Jiangsu Province from 2005 to 2015, and assess the outputs of each schistosomiasis control project. RESULTS The overall productive efficiency of schistosomiasis control programs in Jiangsu Province showed an increasing tendency, and the mean fluctuation of annual TFP was 2.3%. The comprehensive technical efficiency, including pure efficiency and scale efficiency, appeared a steady increase with minor fluctuations, and the mean fluctuation of annual comprehensive technical efficiency was 3.8%. The growth rate of technical progress fluctuated greatly from 2005 to 2011, and showed a steady increase from 2012 to 2015, which became a major contributor to the growth of TFP. A higher growth rate of TFP was seen in Huai ' an and Changzhou cities, which showed a greater comprehensive technical efficiency, and a large fluctuation was observed in the growth rate of technical progress in Yancheng, Nanjing, Huai ' an and Yangzhou cities. CONCLUSIONS There is a continuous improvement in the technical level of schistosomiasis control programs in Jiangsu Province, and technical application and supervision and management capacity also show a steady increase. In addition, the application of new techniques and new strategies contributes greatly to TFP growth. In the future, the investment into new techniques and new strategies should be increased to ensure the sustainable schistosomiasis control in Jiangsu Province.

Abstract
Objective: To investigate the food source of water of college students from Hebei Province in spring. Methods: In March 2017, the subjects were recruited in a college in Baoding, Hebei Province. 156 students completed the investigation. All foods were collected for 3 consecutive days using duplicate portion study combined with weighing method to test the water content of various foods. To analyze the water content of the food and calculate the proportion to the total amount of food water intake, the edible parts of each meal were divided into staple food, dishes, porridge, soup and snacks. Body mass index (BMI) was grouped according to quartiles, and the differences in food intake and food water sources among subjects of different genders and BMI were compared. Results: The age of subjects was (19.8±1.1) years old, including 80 male students. The median intake of staple food, dishes, porridge, soup and snacks per day was 562 g, 743 g, 111 g, 102 g and 0 g, respectively. The median intake of water from staple food, dishes, porridge, soup and snacks per day was 301 ml/d, 620 ml/d, 97 ml/d, 93 ml/d and 0 ml/d, respectively. The median ratio of water intake to total food water intake of staple food, dishes, porridge, soup and snacks was 27%, 53%, 8%, 8% and 0%, respectively. The median intake of water from staple food and dishes in male students was significantly higher than that of female students (P<0.05). The amount of water intake from porridge of female students was significantly higher than that of male students (P<0.05). There was no significant difference in the water intake from soup and snacks between different genders. There was no significant difference in food intake and food water sources among college students with different BMI (P>0.05). Conclusion: The food source of water of college students from Hebei Province in spring is mainly based on dishes and staple foods. The food source of water for boys and girls is different.

Abstract
At present, methods of water-intake survey include government, industry, sector statistics data, dietary survey (24 hours dietary recall, dietary record and food frequency questionnaire), fluid intake survey (retrospective fluid-intake questionnaire, 1-5 days 24 hours fluid-intake survey, 7 days 24 hours fluid-intake record), weighing method with the food composition table, weighing method, duplicate portion method and chemical analysis, and so on. The method of 7 days 24 hours fluid-intake record is an internationally recognized and authoritative method for fluid-intake survey with the highest accuracy, which can reflect the differences of fluid intake between working and non-working days, and can obtain detailed data on behaviors and patterns of fluid water, such as the time, types and places of fluid intake. The method of combining weighing method, duplicate portion method and chemical analysis is used to analyze water intake from food with the highest accuracy, which can be used in an extensive range of population and areas, but with high cost and complex operating steps. It is of great practical significance to compare and evaluate the advantages and disadvantages of different methods about water-intake survey, which will be helpful for researchers to choose appropriate methods for water-intake survey to obtain accurate and representative data in various areas, different population, and complex circumstances.

Abstract
OBJECTIVE To understand the potential risk of schistosomiasis transmission in Xiuzhou District of Jiaxing City, so as to provide the scientific evidence for consolidating schistosomiasis control achievements. METHODS Fixed and mobile surveillance sites were set up in Xiuzhou District of Jiaxing City from 2013 to 2015. Oncomelania hupensis snails was surveyed historical snail habitats, current snail habitats, and suspected snail habitats. The schistosome infections were identified using serological and parasitological testing among local residents and mobile populations. In addition, the survival and reproduction of snails imported into Xiuzhou District was observed, and the schistosome infection in wild reservoir hosts was detected. RESULTS A total of 540.14 hm2 of settings were surveyed in Xiuzhou District, Jiaxing City from 2013 to 2015, and 1.65 hm2 of snail habitats were identified. The snail habitats were mainly located in dry lands, and no infected snails or importation of snails were found. During the period from 2013 to 2015, a total of 7 668 local residents and mobile populations were examined in Xiuzhou District, and no new local infections were detected; however, three imported schistosomiasis cases were identified. Field simulation experiment showed that the imported snails laid eggs and reproduced in Xiuzhou District, and no schistosome infections were found in wild animals. CONCLUSIONS There are still residual Oncomelania snails and imported schistosomiasis patients in Xiuzhou District of Jiaxing City; therefore, the surveillance and management of local Oncomelania snails and imported schistosomiasis should be intensified to reduce the risk of schistosomiasis transmission.

Abstract
Objective: To understand the epidemiological characteristics of one large HIV molecular transmission cluster in Jiaxing city, Zhejiang province, 2017 in order to select those people under high-risk and providing basis for programs on prevention. Methods: During 2017, newly diagnosed HIV/AIDS cases in this city were recruited. Plasma samples were collected from subjects, followed by RNA extraction, RT-PCR and nest-PCR for pol gene amplification, before being sequenced and aligned. Mega 6.0 software was used to construct phylogenetic tree, and Cytoscape 3.6.0 software was used to identify HIV molecular transmission clusters. Cases within the large transmission clusters were investigated, using a field-epidemiology-questionnaire. Data related to socio-demographics and previous sexual behaviors were collected and EpiData 3.0 and SPSS 20.0 software were used. Results: In the large transmission cluster with subtype identified as CRF07_BC, in Jiaxing, 2017, 26 cases of the total 30 cases were investigated. A total of 80.8% (21/26) could be identified as newly infected within the last two years and 30.8%(8/26) could be identified as newly infected within the last one year, including 22 cases infected locally. Among several infected cases who were at age 45 years or older, they admitted that they had experienced unprotected sexual contacts in local city for long time and having had more than 10 disclosed sexual contacts within the last two years at the local venues. Conclusions: This molecular cluster had been formed and scaled up quickly in recent two years, it has played an important role in promoting and scaling up the HIV transmission. Three cases identificed as high risk played an importantrde role in scaling up this cluster.

Abstract
Objective:To determine the diagnostic role of diffusionweighted imaging(DWI) and apparent diffusion coefficient(ADC) under different b values in differentiating benign and malignant thyroid nodules by using postoperative histopathological results were taken as the reference standard. Method: From January 2017 to June 2018, 64 patients with thyroid nodules diagnosed by ultrasound in the head and neck surgery of Shanxi Cancer Hospital were collected, and a total of 80 nodules were collected. The Philips 3.0T superconducting magnetic resonance imaging system was used for T1 weighting, T2 weighting, and DWI horizontal axis scanning imaging. The b values were 300, 500, 800 and 1 000 s/mm², respectively. Taking postoperative histopathological results as the reference standard, the ADC values of thyroid nodules of all subjects were calculated and compared, and the working characteristics(ROC) curves of all subjects with b values were drawn, the area under the curve was calculated, and the threshold value of differentiating benign and malignant thyroid nodules was obtained. Result:A total of 80 nodules, 33 malignant and 43 benign were excluded, including 1 diffuse b-cell non-hodgkin's lymphoma, 2 parathyroid cysts, and 1 pure cystic patient. A total of 76 nodules were included. When b values were 300, 500, 800 and 1 000 s/mm², the average ADC values of malignant nodules were(1.498±0.210) ×10⁻³mm²/s, (1.311±0.190) ×10⁻³mm²/s, (1.134±0.170) ×10⁻³mm²/s, (0.972±0150) ×10⁻³mm²/s. The mean ADC values of benign nodules were(2.207±0.390) ×10⁻³mm²/s, (1.928±0.430) ×10⁻³mm²/s, (1.702±0.410) ×10⁻³mm²/s,(1.557±0.420) ×10⁻³mm²/s. At the same b value, the average ADC value of malignant nodules was lower than that of benign nodules, and the difference was statistically significant(t values were 9.279,7.641,7.301,7.569, P values were 0.000,0.000,0.000,0.000,0.000). The average ADC values of the benign and malignant nodules decreased with the increase of b value, and the difference was statistically significant(the F values of the benign and malignant groups were 210.091 and 353.822, respectively,P values are 0.000, 0.000). Under different b values, the area(AUC) of ROC curve is 0.927,0.884,0.878,0.901,and 95%CI are 0.862-0.993,0.804-0.956,0.794-0.962 and 0.829-0.972, respectively. When b value is 300 s/mm², AUC is the largest, indicating that it is the best indicator to distinguish benign and malignant thyroid nodules. The diagnostic threshold of benign and malignant nodules is 1.802×10⁻³mm²/s. Specificity, sensitivity, accuracy, positive predictive value, and negative predictive value were 95.00%,86.11%,90.79%,93.94% and 88.37%, respectively. Conclusion: DWI is a noninvasive diagnostic tool used to identify benign and malignant thyroid nodules. It can help to make a definite diagnosis before surgery and reduce the unnecessary burden of surgery.

Abstract
Objectives: To investigate the total fluids intake among college students in spring from Hebei. Methods: In March 2017, the subjects were recruited in a college in Baoding, Hebei Province. 156 students completed the investigation. Total drinking fluids was assessed by 7-day 24-hour fluid intake questionnaire, with a quantitative tool. The water from food was assessed by duplicate portion method. The sources of total fluids intake among subjects were analysed. Results: The age of subjects was (19.8±1.1) years old, including 80 male students. The median amounts of total fluids intake, total drinking fluids and water from food were 2 324, 1 135 and 1 174 ml, respectively. The proportions of total drinking fluids and water from food in total fluids intake were 51%±9% and 49%±10%. Only 19.9% (n=31) and 18.6% (n=29) of college students had adequate total fluids intake and total drinking fluids, according to the recommendation of China. The median amounts of total fluids intake, total drinking fluids and water from food were 3 210, 1 860 and 1 093 ml/d, respectively. The proportion of total drinking fluids in total fluids intake was 61%±7%, which were all higher than those who did not reach the recommended intake (2 158, 1 000, 1 149 ml/d; drinking fluids accounting for 46%±8% of total fluids intake) (P<0.05). Conclusion: The amounts of total fluids intake and total drinking fluids of college students in Hebei Province are lower than the recommended intake in China. The contributions of total drinking fluids and water from food to total fluids intake were nearly same.

Abstract
To reveal the association between retinal microvasculature changes and coronary heart disease (CHD), we assessed the full retinal thicknesses of eight areas, the vessel density of four layers (consisting of nine areas) and the flow area in two layers with optical coherence tomography angiography (OCTA) in CHD patients and healthy controls. The mean vessel density of several layers was significantly lower in patients. The difference in choroid capillary flow (negative correlation) between the two groups was significant. Decreased vessel density and blood flow were associated with coronary artery and branch stenosis. The decreases in retinal vessel density, choroidal vessel density, and blood flow area are closely related to coronary artery and branch stenosis.

Abstract
Objective: To study the contamination, serotype, pulsed field gel electrophoresis (PFGE) and drug resistance of listeria monocytogenes (L.monocytogenes) in the process of restaurant kitchens in Heilongjiang Province. Methods: Seventeen typical restaurants were selected from three cities in Heilongjiang Province in 2016, and 590 kitchen samples were collected and tested according to the national standard method. The serotype, pulsed field gel electrophoresis (PFGE) and drug resistance of isolated strains were analyzed. Results: L. monocytogenes was found in 104 of 590 of the samples analysed (17.63%). The isolates belong to six serotypes (1/2 a, 1/2 b, 1/2c, 3a, 3 b, 4 b) and self-condensing bacteria, and 57.38% (70 strains) of the strains belong to serotype 1/2b. Two highly pathogenic serotype 4b was detected for human listeria disease. The results of PFGE analysis show that the bacteria have cross-contamination in the environment, tools, equipment, food and personnel. The drug resistance results showed that 2 strains were resistant to tetracycline, 1 strain was resistant to erythromycin, 13 strains were intermediate to tetracycline, and 2 strains were resistant to tetracycline and erythromycin. Conclusion: There is a certain degree of L. monocytogenes cross-contamination in the catering kitchen in Heilongjiang Province. And an important serotype 4b that can cause human Listeria disease was detected.

Abstract
Oxaliplatin is commonly used in managing malignancy, including colorectal cancer. While treatment often fails due to decreased drug sensitivity, the mechanisms involved are not clear. In this study, we investigate how exosomal miR-19b participates in oxaliplatin sensitivity and then prove that miR-19b down-regulates oxaliplatin sensitivity of sw480 cells. We found that suppressing the secretion of exosomal miR-19b with gw4869 promotes sw480 cell oxaliplatin sensitivity. Our combined results demonstrate for the first time that miR-19b regulates the oxaliplatin sensitivity of sw480 cells and provides a unique mechanism mediated by gw4869 to modulate oxaliplatin sensitivity by suppressing exosomal miR-19b release.

Abstract
OBJECTIVE To investigate the clinical correlation between the manifestations of neuropsychiatric lupus (NPSLE) and brain magnetic resonance imaging (MRI). METHODS Retrospective analysis of 65 neuropsychiatric lupus patients with brain MRI and clinical data from Peking University Third Hospital from January 2006 to October 2016, which was classified by rheumatologist, neurologists, and radiologists based on their brain MRI findings. The correlation between brain MRI findings and clinical manifestations was analyzed. RESULTS The characteristics of the brain MRI of the 65 patients were divided into 6 categories: 16 cases (25%) with demyelination in the white matter, 15 cases (23%) with cerebrovascular disease, including 4 cases (6%) with large vascular disease and 11 cases (17%) with small vessel disease, 4 cases (6%) with inflammation, 4 cases (6%) with edema, 13 cases (20%) with multiple manifestation coexistence, and 13 cases (20%) without any abnormality. Except for 4 cases of brain MRI with edema, the clinical manifestations were only epileptic seizures, other patients had complex and diverse clinical manifestations, including epileptic seizures, lupus-like headaches, mental symptoms, blurred vision, peripheral neuropathy and disturbance of consciousness. The incidence of epileptic seizures in patients with edema of MRI is significantly higher than that of other patients, and the therapeutic response time is the shortest. CONCLUSION Multidisciplinary collaboration divides the MRI findings of neuropsychiatric lupus patients into six categories. This classification method helps clinicians to predict and intervene early possible neuropsychiatric symptoms to guide clinical treatment.

Abstract
Objective: To compare the operation time, estimated blood loss, clinical outcome and correction of lumbar lordosis between oblique lateral interbody fusion (OLIF) and transforaminal lumbar interbody fusion (TLIF) in patients with degenerative lumbar diseases. Methods: Seventy-three patients who underwent OLIF or TLIF surgery from January 2016 to December 2017 in Sir Run Run Shaw Hospital Zhejiang University were analyzed in this retrospective case-control study. The patients included 31 males and 42 females, with a mean age of 65.8 years (range, 36-88 years). Of the patients, there were 9 cases of calcified disc herniation, 34 cases of spinal stenosis, 17 cases of degenerative spondylolithesis, 12 cases of degenerative scoliosis and 1 case of isthmic spondylolithesis. According to the type of surgery, patients were divided into OLIF group (34 cases) and TLIF group (39 cases). The operation time, estimated blood loss and transfusion were recorded, pre-and post-operative visual analogue scale (VAS) for back pain and Oswestry Disability Index (ODI) were evaluated, and pre- and post-operative lumbar lordosis (LL) and fused segment lordosis (FSL) were measured. Student t test were used in comparison between groups. Results: Ten (29.4%) patients in OLIF group and all 39 (100%) patients in TLIF group were supplemented with posterior instrumentation (χ(2)=41.013, P<0.05). The average operation time and estimated blood loss was significantly lower in OLIF group than in those in TLIF group[(163±68) vs (233±79) min, (116±148) vs (434±201) ml, t=4.019, 6.964, both P<0.05]. There was no significant differences in decreases value in VAS and ODI after surgery between the two groups (t=1.716, 0.522, both P>0.05). The correction of LL was 4.0°±10.0° in the OLIF group and 4.2°±6.1° in the TLIF group; the correction of FSL was 4.1°±7.0° in the OLIF group and 5.2°±4.6° in the TLIF group, with no significant differences between the two groups too (t=0.139, 0.805, both P>0.05). The correction of LL was significantly higher in OLIF group with posterior instrumentation than that in TLIF group (9.9°±11.1° vs 4.2°±6.1°, t=2.180, P<0.05). Conclusions: Both OLIF and TLIF can restore LL to some extent, but OLIF has obvious advantages in the operation time and blood loss during surgery. When supplemented with posterior instrumentation, OLIF can achieve better correction of LL than TLIF.

Abstract
Wire and nonparallel plate electrode-type electrostatic air accelerators have attracted significant interest. The physical process involved in using accelerators is complicated. Moreover, mechanisms are unclear, especially for accelerators with double- and multiwire electrodes. In this study, the two-dimensional (2D) model of a wire-nonparallel plate-type accelerator validated by experiments is established with a finite element method. Onset voltage, average current, and outlet average velocity are analyzed with respect to different parameters. Onset voltage is derived by the proposed quadratic regression extrapolation method. Moreover, current is affected by interference and discharge effects, while velocity is also influenced by the suction effect. For the single-wire electrode, high wind speed can be obtained by either increasing channel slope or placing the wire near the entry section. For the double-wire electrode, velocity can be further increased when one of the wires is placed near the inlet and the distance between the two wires is widened. Comparatively, the velocity of the three-wire electrode is higher with larger gaps between wires and stronger discharge effect. The highest velocity is obtained by the four-wire electrode. Comparisons indicate that higher velocity can be obtained with weaker interference effect, stronger suction effect, and intensified discharge effect. Optimum parameter combinations are considered by the Taguchi method. Consequently, velocity can be enhanced by more than 39% after optimization compared with the reference design.

Curcumin attenuates heat-stress-induced oxidant damage by simultaneous activation of GSH-related antioxidant enzymes and Nrf2-mediated phase II detoxifying enzyme systems in broiler chickens. Poult Sci 2018; 97:1209-1219. [PMID: 29438543 DOI: 10.3382/ps/pex408] [Citation(s) in RCA: 70] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2017] [Accepted: 11/28/2017] [Indexed: 12/16/2022] Open
Abstract
The object of this study was to investigate the effect of curcumin on modulating the glutathione (GSH)-related antioxidant enzymes and antioxidant responses via NF-E2-related factor 2 (Nrf2) signaling pathway in heat-stressed broiler chickens. A total of 400 one-day-old male Arbor Acres broiler chicks was reared in an environmentally controlled room. At 21 d, broiler chicks were divided into 5 treatment groups and were fed one of 4 diets under 2 temperature conditions: 22°C + a basal diet (CON treatment); 34°C for 8 h (0900-1700) + a basal diet supplemented with 0, 50, 100, or 200 mg/kg curcumin (HS, CMN1, CMN2, and CMN3 treatments, respectively). The heat treatment lasted for 20 consecutive days. The results showed that heat stress significantly increased (P < 0.05) the weekly rectal temperature and average head and feet temperature. Compared to the HS treatment, feed conversion was significantly decreased (P < 0.05) in CMN1 and CMN2 treatments. CMN1 administration significantly improved (P < 0.05) the pH24 of muscle. The abnormal changes of serum malonaldehyde and corticosterone concentrations were prevented (P < 0.05) by curcumin. Mitochondrial GSH concentration in the liver was significantly increased (P < 0.05) in CMN1 and CMN2 treatments compared with the HS treatment. The CMN1, CMN2, and CMN3 supplementations significantly increased (P < 0.05) γ-GCL, GSH-Px, and GST activities. Curcumin significantly increased (P < 0.05) the expression of Nrf2, HO-1, and γ-GCLc in the liver as compared to the CON diet. The expression of Cu/ZnSOD and CAT were increased (P < 0.05) by feeding CMN2, respectively, as compared to the HS treatment. It was concluded that curcumin supplementation enhanced the resistance of broilers to heat stress, as evidenced by reversing the FC, increasing the GSH content and GSH-related enzyme activities, and inducing the expression of Nrf2 and Nrf2-mediated phase II detoxifying enzyme genes.

Abstract
Objective: To investigate the clinical characteristics of patients with hydrofluoric acid (HF) burns. Methods: Clinical data of 316 patients with HF burns admitted to Zhejiang Quhua Hospital from January 2004 to December 2016 were retrospectively analyzed. Patients were divided into non and mild poisoning group (NMP, n=157), moderate poisoning group (MP, n=120), and severe and fatal poisoning group (SFP, n=39) based on the severity of poisoning. Occurrences of hypocalcemia, hypomagnesemia, hypokalemia, and hyperkalemia of patients within 24 hours after admission were recorded. Values of emergency urinary fluoride of patients on admission were recorded. Values of urinary fluoride of patients admitted to hospital in 4 hours post injury in groups MP and SFP at post injury hour 4, 12, and 24 and on post injury day 2, 3, 4, 5, 6, and 7 were also recorded. Electrocardiographic abnormalities of patients within 24 hours after admission were recorded. Data were processed with chi-square test, Kruskal-Wallis H test, and Mann-Whitney U test. Results: (1) Hypocalcemia, hypomagnesemia, and hypokalemia occurred in some patients in each of the three groups, but no patient had hyperkalemia. Taking serum calcium namely total serum calcium as reference, the incidence rate of hypocalcemia of patients in group NMP was close to that in group MP (χ(2)=0.05, P>0.05). The incidence rate of hypocalcemia of patients in group SFP was significantly higher than that in group NMP or group MP (χ(2)=10.53, 7.92, P<0.01). The incidence rates of hypokalemia in the three groups were close (χ(2)=0.63, P>0.05). Taking serum ionized calcium as reference, the incidence ratio of hypocalcemia of patients in group NMP was close to that in group MP (χ(2)=0.01, P>0.05), while there were statistically significant differences in incidence ratio of hypocalcemia of patients between group SFP and each of group NMP and group MP (χ(2)=4.66, 4.47, P<0.05). Taking serum calcium as reference, the incidence rate of hypocalcemia of patients was 7.3% (23/316). Taking serum ionized calcium as reference, the incidence rate of hypocalcemia of patients was 60.0% (42/70), which was significantly higher than that of taking serum calcium as reference (χ(2)=113.74, P<0.01). The incidence rates of hypomagnesemia of patients in groups MP and NMP were close (χ(2)=0.02, P>0.05). The incidence rate of hypomagnesemia of patients in group SFP was significantly higher than that in group NMP or group MP (χ(2)=14.69, 9.94, P<0.01). (2) The urinary fluoride levels were tested in 288 patients, with the value of emergency urinary fluoride of patients on admission 0.2-590.0 mg/L. The values of urinary fluoride of 202 patients were above the normal value. The values of emergency urinary fluoride of patients in groups NMP, MP, and SFP were 2.15 (1.11, 4.30), 5.89 (1.72, 14.25), and 36.0 (13.2, 103.2) mg/L, respectively. The values of emergency urinary fluoride of patients in groups MP and SFP were significantly higher than the value in group NMP (χ(2)=23.28, 66.03, P<0.01). The value of emergency urinary fluoride of patients in group SFP was significantly higher than that in group MP (χ(2)=39.23, P<0.01). The value of urinary fluoride of 33 patients admitted to hospital within 4 hours post injury in groups MP and SFP reached the top at 4 hours post injury and then gradually declined, which returned to normal on about 5 days post injury. The values of urinary fluoride of patients in group SFP at 4, 12, and 24 hours post injury and on 2, 3, 4, 5, 6, and 7 days post injury were significantly higher than those in group MP (Z=-4.28, -4.15, -3.81, -4.21, -2.48, -2.06, -2.31, -2.68, -3.03, P<0.05 or P<0.01). (3) Twenty-seven patients had electrocardiographic abnormality. There were 12 patients with T wave changes (the most common), 8 patients with ST-T changes, 6 patients with ventricular arrhythmias, 6 patients with conduction block, and 1 patient with broadened QRS waveform. There was no patient with prolonged Q-T interval. The ratios of patients with the above electrocardiographic abnormalities in group SFP were higher than those in group NMP and group MP. Conclusions: Clinical manifestations of patients with HF burn are hypocalcemia, hypomagnesemia, hypokalemia, and electrocardiographic abnormality. In addition to routine serum electrolyte and electrocardiogram monitoring, the levels of serum ionized calcium and urinary fluoride can be helpful to evaluate the severity of illness of the patients.

Abstract
Objective: To retrospectively explore the effects of modified dosage of calcium gluconate (CG) on the patients with hydrofluoric acid burns not in hands or feet. Methods: One hundred and sixty patients with hydrofluoric acid burns not in hands or feet were hospitalized in our burn ward from January 2004 to December 2017. Based on the dosage of CG at different admission time, 76 patients hospitalized from January 2004 to December 2012 were included in traditional group, and 84 patients hospitalized from January 2013 to December 2017 were included in modified group. For patients in the two groups, subcutaneous injection of CG solution at one time was immediately conducted on admission in topical treatment. In traditional group, the injection was CG solution with mass concentration of 100 g/L. For wounds of superficial partial-thickness and above degree, CG solution was prescribed at the dosage of 50 mg/cm(2). Wounds of superficial-thickness or mass fraction of hydrofluoric acid less than 20.0% did not receive injection. In modified group, the mass concentration of CG solution for injection was diluted with normal saline to 25 g/L. For wounds of deep partial-thickness and above degree, CG solution was prescribed at the dosage of (50×mass fraction of hydrofluoric acid) mg/cm(2). For wounds of superficial partial-thickness, CG solution was prescribed at the dosage of (25×mass fraction of hydrofluoric acid) mg/cm(2). For wounds of superficial-thickness, CG solution was prescribed at the dosage of 2.5 mg/cm(2). For systemic treatment, the injection velocity of CG solution via venous access was adjusted according to the level of serum calcium namely total serum calcium of patients in traditional group. In modified group, serum ionized calcium was additionally detected through automatic blood gas analyzer by the bed to regulate the injection velocity of CG via venous access. The incidence rate of hypercalcemia and mortality of patients after treatment in the two groups, and the situation about treatment of survivors in the two groups were analyzed. Data were processed with chi-square test, Fisher's exact probability test, t test, and Mann-Whitney U test. Results: (1) After treatment, 9 patients (11.8%) had hypercalcemia, while the other 67 patients (88.2%) did not have hypercalcemia in traditional group. Two patients (2.4%) had hypercalcemia, while the other 82 patients (97.6%) did not have hypercalcemia in modified group. The incidence rate of hypercalcemia of patients in traditional group was significantly higher than that in modified group (χ(2)=5.579, P=0.02). (2) There were two deaths (2.6%) and 74 survivors (97.4%) in traditional group, while there were two deaths (2.4%) and 82 survivors (97.6%) in modified group. The mortalities of patients in the two groups were close (P>0.05). (3) The ratios of eschar excision and skin grafting and hyperplastic scar formation, wound healing time, and ratio of esophageal scar stenosis of survivors in the two groups were close (χ(2)=0.002, 0.054, Z=0.66, P>0.05). Conclusions: Hydrofluoric acid is highly dangerous. The early management of patients with hydrofluoric acid burns emphasizing specialized dosage of CG for treatment can be helpful to reduce incidence of complications and improve the safety of treatment.

Abstract
Objective: To understand the distribution of HIV-1 subtype diversity and its transmission characteristics in Zhejiang province. Methods: A total of 302 newly diagnosed HIV-1 positive patients were selected through stratified random sampling in Zhejiang in 2015. HIV-1 pol genes were sequenced successfully with reverse transcription PCR/nested PCR and phylogenetic analysis was conducted for 276 patients. Then a molecular epidemiologic study was performed combined with field epidemiological investigation. Results: Of 276 sequence samples analyzed, 122 CRF07_BC strains (44.2%), 103 CRF01_AE strains (37.3%), 17 CRF08_BC strains (6.1%), 9 B strains (3.2%), 6 CRF55_01B strains (2.2%), 5 C strains (1.8%), 1 CRF59_01B strain (0.4%), 1 CRF67_01B strain (0.4%), 1 A1 strain (0.4%), and 11 URFs strains (4.0%) were identified. Phylogenetic analysis revealed 16 clusters with only 15.1% (34/225) sequences involved among CRF07_BC and CRF01_AE strains. The clustered cases in MSM were higher than that in populations with other transmission routes. And clusters existed between the populations with different transmission routes. Conclusion: The major strains of HIV-1 in Zhejiang are CRF07_BC and CRF01_AE. The HIV subtypes showed more complexity in Zhejiang. It is necessary to strengthen the surveillance for HIV subtypes, carry out classified management and conduct effective prevention and control in the population at high risk.

Abstract
Objective: To understand the characteristics of distribution on HIV-1 subtypes and the transmission clusters in Yiwu in Zhejiang province. Methods: A cross-sectional study of molecular epidemiology was carried out on newly reported HIV/AIDS cases in Yiwu. RNA was extracted from 168 plasma samples, followed by RT-PCR and nest-PCR for pol gene amplification, sequencing, phylogenetic tree construction used for analyzing the subtypes and transmission clusters. Mutations on drug resistance was analyzed by CPR 6.0 online tool. Results: Subjects were mainly males (86.3%, 145/168), with average age as (39.1±13.4) years old and most of them were migrants (66.7%, 112/168). The major routes of transmission included homosexual (51.2%, 86/168) and heterosexual (48.8%, 82/168) contacts. The rate of success for sequence acquisition was 89.9% (151/168). The dominant subtypes showed as CRF01_AE (74, 49.0%) and CRF07_BC (64, 42.4%), followed by CRF08_BC (5, 3.3%), CRF55_01B (3, 2.0%), each case of subtype B, CRF45_cpx, CRF59_01B, CRF85_BC and URF (B/C). CRF45_cpx and CRF85_BC were discovered the first time in Zhejiang province. Twenty-six transmission clusters involving 65 cases were found, with the total clustered rate as 43.0% (65/151), in which the CRF01_AE clustered rate appeared as 54.1% (40/74), higher than that of CRF07_BC (21/64, 32.8%). The average size of cluster was 2.5 cases/cluster, with average size of cluster in CRF01_AE patients infected through heterosexual transmission as the largest (3.5 cases/cluster). The prevalence of transmitted drug resistance was 4.6% (7/151). Seven cases with surveillance drug resistant mutations (SDRM) were found, including 5 cases of M46L (3.3%), and one case of F77L or Y181C. Conclusion: HIV genetic diversity and a variety of transmission clusters had been noticed in this study area (Yiwu). Programs on monitoring the subtypes and transmission clusters should be continued and strengthened.

Abstract
The removal of phenanthrene and iodine from aqueous solutions in single and binary systems by inactivated soil indigenous bacterial biomass (SIBB), as well as affecting factors, were evaluated. Sorption kinetic and isotherm studies were carried out to investigate the synergistic effects of phenanthrene and iodine. Optimal parameters for the biosorption process included a solution pH of 6.0 and biosorbent dosage of 0.75 g L−1. The ionic strength significantly decreased the biosorption of both phenanthrene and iodine in single conditions, while no obvious influences were found in the binary conditions. A pseudo-second-order model was well fitted to the kinetic biosorption data for both phenanthrene and iodine. The results showed that the presence of co-solute accelerated the biosorption processes and the pseudo-second-order biosorption rates (k2) for phenanthrene and iodine increased from 0.005441 to 0.009825 g mg−1 min−1 and from 0.000114 to 0.000223 g mg−1 min−1, respectively. The SIBB showed strong affinity with both phenanthrene and iodine, with a partition coefficient Kd (Linear model) of 6892.4 L kg−1 for phenanthrene and affinity parameter KL (Langmuir model) of 232 500 L kg−1 for iodine. The presence of co-solute illustrated a synergistic effect on the biosorption of phenanthrene and iodine due to intermolecular forces between phenanthrene and iodine, enhancing the Kd of 34.7% for phenanthrene and KL of 107.0% for iodine, respectively. The results suggested that SIBB was an effective material for the simultaneous biosorption of phenanthrene and iodine from aqueous solutions. Co-solute significantly enhanced the sorption affinity of phenanthrene and iodine by bacterial biomass.![]()

Abstract
Objective: To investigate the effect of human umbilical cord mesenchymal stem cells (hUCMSCs) on the immune function and prognosis of patients with decompensated hepatitis B cirrhosis. Methods: A total of 65 patients with decompensated hepatitis B cirrhosis were divided into observation group and control group. The patients in the observation group were given intervention (via the proper hepatic artery or the portal vein) and intravenous infusion of 4×108 hUCMSCs in two doses, as well as the same basic treatment as in the control group. The patients in the control group were given conventional medical treatment. ELISA as used to measure the serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNFα), interleukin-10 (IL-10), and transforming growth factor-β (TGFβ) in the observation group before surgery and at 1 week after surgery, as well as the serum levels of IL-6, TNFα, IL-10, and TGFβ in the control group on admission and at 1 week after admission. Flow cytometry was used to measure the percentage of lymphocyte subsets in the observation group before surgery and at 1 week after surgery, as well as that in the control group on admission and at 1 week after admission. In addition, the patients' prognosis and major complications during hospitalization were observed in both groups, and the patients were followed up for 24 weeks to record the number of deaths. The t-test was used for comparison of continuous data, and the chi-square test was used for comparison of categorical data which were expressed as percentages. Results: At 1 week after the transplantation of hUCMSCs, compared with the control group, the observation group had significant reductions in the serum levels of IL-6 and TNFα and significant increases in the serum levels of IL-10 and TGFβ (all P < 0.001), as well as significant increases in the percentages of T4 cells and Treg cells and significant reductions in the percentages of T8 cells and B cells (all P < 0.05). There were no significant differences in the changes in T3 cells and natural killer cells between the two groups (P > 0.05). Compared with the control group, the observation group had a significantly lower probability of progression to liver failure (6.45% vs 14.71%, P = 0.017). Conclusion: In the treatment of patients with decompensated hepatitis B cirrhosis, transplantation of UCMSCs can inhibit the proliferation of T cells and B cells and the differentiation of T8 cells, upregulate Treg cells, promote the secretion of immunosuppressive cytokines, and reduce the production of inflammatory cytokines. Therefore, it can alleviate liver inflammatory response and liver cell damage and reduce the probability of hepatic failure.

Abstract
The present study was conducted to investigate the influence of dietary supplementation with different levels of fermented Ginkgo biloba leaves (FGBL) on growth performance, slaughter performance, meat quality, antioxidant enzyme capacity, and free radical scavenging activities of muscles in broiler chickens. A total of 648 one-d-old broiler chickens were randomly allocated into six dietary treatments, including control group (CON group: basal diet), FGBL1, FGBL2, FGBL3, FGBL4, and FGBL5 groups (basal diet containing 1.5, 2.5, 3.5, 4.5, and 5.5 g/kg FGBL, respectively). Body weight gain and feed intake were recorded at 1, 21, and 42 d. At 42 d, 2 birds from each replicate were slaughtered. The results indicated that 3.5 g/kg FGBL diet significantly increased (P < 0.05) ADFI and ADG in 1 to 42 d and ADFI in 22 to 42 d compared with the CON group. In 1 to 21 d, 4.5 g/kg FGBL diet improved (P < 0.05) ADFI and ADG. With dietary FGBL increasing, the feed: gain ratio (F/G) in 1 to 21 d was significantly decreased (P < 0.05). However, birds fed with 5.5 g/kg FGBL had a higher (P < 0.05) F/G compared with other groups in 22 to 42 d and 1 to 42 d. In addition, FGBL3 and FGBL4 showed lower (P < 0.05) L* value in breast muscle, cooking loss in thigh muscle and lower 24 h and 48 h drip loss in both breast and thigh muscles than those of other groups. Furthermore, birds in the FGBL3 and FGBL4 groups increased (P < 0.05) the activity of total superoxide dismutase and total antioxidant capability in muscles, and the scavenging activities of 2,2΄-azino-bis (3-ethylbenzothiazoline-6-sulfonic) acid radical, OH•, and O2•- in thigh muscle, decreased (P < 0.05) malondialdehyde concentration in thigh muscle, as compared to the CON group. In conclusion, FGBL had the potential to improve the growth performance, meat quality and antioxidant status of broiler chickens. The optimal dose in the present study of FGBL in broiler diets was from 3.5 to 4.5 g/kg.

Abstract
Objective: To detect the expression of long noncoding RNA(lncRNA)stomach cancer-associated transcript-3(STCAT3) in gastric cancer tissues, adjacent tissues, human gastric cancer cell lines and normal gastric epithelial cell lines, and to investigate the relationship between STCAT3 expression and clinicopathological features and malignant phenotype of gastric cancer. Methods: Quantitative fluorescent real-time polymerase chain reaction (qRT-PCR) was applied to detect the lncRNA STCAT3 expression levels in gastric cancer tissues, paired adjacent non-tumorous tissues, in order to explore the relationship between STCAT3 expression and clinicopathological features of gastric cancer. lncRNA STCAT3 low-expressing and high-expressing gastric cancer cell lines were transfected with expression plasmid to simulate gain-of-function, or interference plasmid to achieve loss-of-function. Cell proliferation was measured with CCK-8 and colony formation assay, cell migration with scratch assay, and cell invasion with Transwell migration assay. human gastric tumor were also transplanted to nude mice to detect the effect of lncRNA STCAT3 on tumorigenesis. Results: The expression of lncRNA STCAT3 was generally up-regulated in gastric cancer tissues compared with the adjacent tissues(12.55±0.16 vs 6.52±0.14), with median expression level in gastric cancer tissues being 6.03 higher (P<0.05). Meanwhile, the expression level of lncRNA STCAT3 in gastric cancer tissues was not correlated with age or gender (both P>0.05), while positively correlated with TNM stage (P<0.05). Interference of lncRNA STCAT3 expression in BGC-823 cells was found associated with significantly suppressed colony formation, proliferation, invasion, and migration (all P<0.05). Over-expression of lncRNA STCAT3 in AGS cells were also founded could promote the gastric cancer cells' proliferation, colony formation, migration, and invasion (all P<0.05). Conclusions: lncRNA STCAT3 may participate in the proliferation and invasion of gastric cancer cells, indicating that dysregulation of STCAT3 expression may play a role in occurrence and development of gastric cancer. lncRNA STCAT3 has the potential to be the biomarker of gastric cancer progression and target in treatment. The underlying mechanism is yet to be further studied.

Abstract
Objective: To explore the value of neuroendoscope and minimal-access in enhanced recovery after surgery of microvascular decompression (MVD) for treatment elderly patients with idiopathic trigeminal neuralgia (ITN). Methods: The clinical data of 62 elderly patients with ITN who undergoing neuroendoscope-assisted minimal-access microvascular decompression were analyzed retrospectively, including operative data and follow-up results. Results: In 62 cases, the effective rate was 96.8%, with 88.7% complete cure and 8.1% little residual pain. Sixty successful cases were followed-up for an average of 61 months.Three cases recurred within 3 years after operation.Eight cases had complications after MVD. Conclusions: There was no serious complications that could be ascribed to old age and the operative result was satisfactory compared with younger age cases.Endoscope and minimal-access can help shorten operation time, raise the effectiveness of MVD, reduce postoperative recurrence rate, and enhanced recovery after surgery for elderly patients.
