Abstract
Objective: To compare the efficacy of conventional open ankle fusion and three dimensional(3D) printed guide plate assisted arthroscopic ankle fusion. Methods: A retrospective cohort study was performed on 256 patients with advanced traumatic ankle arthritis, who were admitted to the Department of Orthopaedics, Shanghai Sixth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from May 2018 to February 2023 and underwent ankle fusion procedures. The study cohort comprised 119 males and 137 females, with an age of (59.6±9.5) years (range: 37 to 83 years). Among them, 175 cases underwent internal fixation with plates and screws (58 cases through the combined medial and lateral approach, and 117 cases through the simple lateral approach), 48 cases underwent internal fixation with screws through the anterior approach (conventional open group), and 33 cases underwent minimally invasive arthroscopic ankle fusion assisted by 3D printed guide plate (3D printed guide plate arthroscopy group). Propensity score matching was employed to achieve a 1∶1 match(caliper value=0.02) between the baseline characteristics of patients in the 3D printed guide plate arthroscopy group and the conventional open group. Perioperative and follow-up data between the two groups were compared using the t-test, Mann-Whitney U test, Wilcoxon signed rank test,χ² test, or Fisher's exact probability method, as appropriate. Results: Matching was successfully achieved with 20 cases in both the 3D printed guide plate arthroscopy group and the conventional open group, and there were no statistically significant differences in baseline characteristics between the two groups (all P>0.05). The operation time in the 3D printed guide plate arthroscopy group was significantly longer than that in the conventional open group ((88.9±5.6) minutes vs. (77.9±11.7) minutes;t=-2.392, P=0.022), while the frequency of intraoperative fluoroscopies ((1.7±0.8) times vs. (5.2±1.2) times; t=10.604, P<0.01) and length of hospitalization ((5.5±0.9) days vs. (6.4±1.5) days;t=2.480, P=0.018) were significantly lower in the 3D printed guide plate arthroscopy group compared to the conventional open group. The fusion rate was 95.0% (19/20) in the 3D printed guide plate arthroscopy group and 85.0% (17/20) in the conventional open group, with no statistically significant difference between the two groups (χ²=1.111,P=0.605). The fusion time was (12.1±2.0) weeks in the conventional open group and (11.1±1.7) weeks in the 3D printed guide plate arthroscopy group, with no statistically significant difference between the two groups (t=1.607, P=0.116). At the final follow-up, the American Orthopedic Foot and Ankle Society ankle hindfoot scale was (72.6±5.5)points in the 3D printed guide plate arthroscopy group and (70.5±5.8)points in the conventional open group, with no statistically significant difference between the two groups (t=-1.003, P=0.322). The VAS score of the 3D printed guide plate arthroscopy group was (M(IQR)) 1.50 (1.00) points, lower than that of the conventional open group by 3.00 (1.00) points, with statistically significant differences (Z=-3.937, P<0.01). The complication rate was significantly higher in the conventional open group (25.0%(5/20) vs. 5.0%(1/20), P=0.182). Conclusion: 3D printed guide plate assisted arthroscopic ankle fusion exhibited several advantages, including reduced frequency of fluoroscopies, alleviation of postoperative pain, and decreased complications and length of hospitalization.

Abstract
Objective: To investigate the clinical phenotype and genetic characteristics of patients with Fabry disease caused by a GLA variant, IVS4+919G>A. Methods: It was a prospective study. Fabry disease screening was conducted among high-risk population in Ninghai from October 2021 to August 2023. Those children with decreased α-galactosidase enzyme activity<2.40 μmol/(L·h) or elavated Lyso-GL-3 level>1.10 μg/L in dried blood spot (DBS) method underwent GLA genetic testing for diagnosis confirmation. Meanwhile, family screening was carried out. A proband and his family members diagnosed with Fabry disease were research subjects. The clinical and genetic characteristics of patients with Fabry disease caused by the GLA variant (IVS4+919G>A) were analyzed. Results: The female proband aged 9.8 years with pain in both lower limbs as the initial symptom was found to have a heterozygous GLA variant IVS4+919G>A among 102 patients. In family screening, there were 4 family members (proband's father, elder sister, elder male cousin and elder female cousin) with Fabry disease and a family member (proband's fifth aunt) with a GLA variant. Among these 4 diagnosed family members, the elder male cousin of the proband, a boy aged 13.2 years had a heterozygous GLA variant, IVS4+919G>A with intermittent pain in both lower limbs as the initial symptom. The proband's father had knee joint pain. The proband's elder sister had decreased vision and his elder female cousin had no obvious symptoms. The proband's fifth aunt with a GLA variant had decreased vision. Conclusions: High-risk screening in children and family screening are helpful for early diagnosis and treatment of Fabry disease. Neuropathic pain may be a early symptom in children with Fabry disease caused by the GLA variant, IVS4+919G>A.

Abstract
OBJECTIVES Computed tomographic perfusion (CTP) can play an auxiliary role in the selection of patients with acute ischemic stroke for endovascular treatment. However, data on CTP in non-stroke patients with intracranial arterial stenosis are scarce. We aimed to investigate images in patients with asymptomatic intracranial arterial stenosis to determine the detection accuracy and interpretation time of large/medium-artery stenosis or occlusion when combining computed tomographic angiography (CTA) and CTP images. METHODS We retrospectively reviewed 39 patients with asymptomatic intracranial arterial stenosis from our hospital database from January 2021 to August 2023 who underwent head CTP, head CTA, and digital subtraction angiography (DSA). Head CTA images were generated from the CTP data, and the diagnostic performance for each artery was assessed. Two readers independently interpreted the CTA images before and after CTP, and the results were analyzed. RESULTS After adding CTP maps, the accuracy (area under the curve) of diagnosing internal carotid artery (R1: 0.847 vs. 0.907, R2: 0.776 vs. 0.887), middle cerebral artery (R1: 0.934 vs. 0.933, R2: 0.927 vs. 0.981), anterior cerebral artery (R1: 0.625 vs. 0.750, R2: 0.609 vs. 0.750), vertebral artery (R1: 0.743 vs. 0.764, R2: 0.748 vs. 0.846), and posterior cerebral artery (R1: 0.390 vs. 0.575, R2: 0.390 vs. 0.585) occlusions increased for both readers (p < 0.05). Mean interpretation time (R1: 72.4 ± 6.1 s vs. 67.7 ± 6.4 s, R2: 77.7 ± 3.8 s vs. 72.6 ± 4.7 s) decreased when using a combination of both images both readers (p < 0.001). CONCLUSIONS The addition of CTP images improved the accuracy of interpreting CTA images and reduced the interpretation time in asymptomatic intracranial arterial stenosis. These findings support the use of CTP imaging in patients with asymptomatic intracranial arterial stenosis.

Abstract
Objective: To investigate the chronic respiratory symptoms and pulmonary function of adult residents in 3 towns of Hongtong County, Shanxi Province, and to explore their risk factors. Methods: The investigation of chronic respiratory symptoms and lung function status of adult residents in Hongdong County is based on the regional population of the entire county in Hongdong County. The project was initiated by the Science and Technology Department of Linfen City and coordinated by the Hongdong County Government. The investigation will be conducted in 3 townships in Hongdong County, Linfen City, Shanxi Province from April to November 2021: Demographic characteristics, respiratory symptoms, smoking dust exposure and other personal history were collected through questionnaires. Physical examination, routine blood tests and lung function tests were also performed on each individual. SPSS 22.0 software was used to conduct t test, χ2 test, ANOVA or Kruskal-Wallis test for statistical analysis of the collected information. Results: 10 945 subjects aged 18-102 years were included in the analysis, of whom 3 754 (34.3%) were male, 1 222 (11.2%) had a history of dust exposure, 7 164 (65.5%) had used straw and firewood as cooking fuel, and 3 296 (30.1%) had a history of smoking. Among the participants, 394 (3.6%), 339 (3.1%), and 1 543 (14.1%) had respiratory symptoms such as chronic cough, sputum, and dyspnea. Statistics showed that the population with chronic respiratory symptoms was more elderly and had a smoking history, and the incidence of chronic respiratory symptoms was higher in those who smoked more than 40 packs a year (all P<0.05). Men with a history of dust exposure were more likely to suffer from chronic cough and expectoration, while emaciation and biofuel use for more than 40 years were more likely to suffer from chronic expectoration and dyspnea (all P<0.05). The median values of forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) and FEV1/FVC in 1 second were 2.19 L/s, 3.24 L and 69.16%, respectively. Among them, the lung function of 5 801 (53.0%) respondents was lower than the expected value. The median FEV1/FVC decreased with the increase of age. The FEV1/FVC of people over 40 years old with smoking history was lower, the dust exposure history of people with decreased lung function was more than that of people with normal lung function, and the incidence of chronic expectoration and dyspnea was higher in people with decreased lung function (all P<0.05). The absolute value and ratio of eosinophils in patients with decreased ventilation function over 60 years old were significantly higher than those with normal ventilation function, but the level of body mass index (BMI) was lower (all P<0.05). Conclusion: In Hongdong County, Shanxi Province, grassroots residents have poor medical awareness, low lung function examination rate, chronic respiratory symptoms and lung function decline are associated with more risk factors. Primary medical institutions need to formulate prevention strategies and carry out lung function detection according to the actual situation, focusing on monitoring and follow-up of high-risk groups to achieve early and timely prevention, diagnosis and treatment of chronic obstructive pulmonary disease.

Abstract
Objective: To understand the incidence of HIV infection, high risk behaviors and pre-exposure prophylaxis/post-exposure prophylaxis (PrEP/PEP) utilization in men who have sex with men (MSM) in Beijing. Methods: Sample size was estimated to be 1 227 persons and 207 person year respectively in the survey and the cohort by using Epi Info 7.0 software. Using convenient sampling method, MSM were recruited by using Wechat app. Questionnaire was completed online to collect the information about demographic characteristics, high risk behavior, and utilization of PrEP/PEP of the MSM. MSM collected dry blood spot (DBS) samples by themselves, and mailed the DBS samples to laboratory for HIV nucleic acid testing. Open cohort was established and those with HIV negative nucleic acid testing results were followed up. Non-conditional binary logistic regression method was used to identify the associated factors for high risk anal sex in the last month and having multiple homosexual partners in the last month. Results: A total of 1 147 MSM were recruited, and follow up for 236 person years was conducted in 956 MSM with negative HIV nucleic acid testing results. The detection rate of new HIV infection was 1.3 per 100 person-years (3/236). During the last month, the proportions of consistent condom use in anal sex and oral sex were 50.7% (238/469) and 4.9% (23/469). In the MSM, 5.9% (43/723) had sex with HIV positive partners in the last month. 9.8% (103/1 049) used PrEP, and 8.7% (91/1 049) used PEP. The proportion of consistent condom use in PrEP and PEP were 34.3% (24/70) and 72.2% (39/54) respectively. Logistic regression analysis revealed that compared with those who used no PrEP/PEP, those who used PrEP/PEP were more likely to have unprotected anal sex in the last month (aOR=3.16, 95%CI:1.45-7.18), and more likely to have multiple homosexual partners in the last month (aOR=2.64, 95%CI:1.19-6.30), and compared with those who used no Rush Popper or drugs in the last month, those who used Rush Popper or drugs in the last month were more likely to have unprotected anal sex in the last month (aOR=2.34, 95%CI:1.67-3.30), and more likely to have multiple homosexual partners (aOR=2.42,95%CI:1.76-3.33). Conclusions: It is necessary to strengthen the health education to promote condom use and introduce the harm of drug use in MSM. In PrEP and PEP services, it is still necessary to suggest consistent condom use for MSM.

Abstract
Objective: To examine the willingness of HIV non-occupational post-exposure prophylaxis (nPEP) among MSM and factors related were also assessed. Methods: The respondent-driven sampling method was used to recruit MSM for a face-to-face interview with a structured questionnaire,the sample size was estimated at 600 subjects. Demographic data, sexual behavior, awareness, and willingness regarding nPEP were collected. The factors related to willingness to nPEP were assessed using complex logistic regression. Results: A total of 14 rounds were recruited and 608 MSM subjects were included in the study. The average age was (41.6±11.0) years. 55.4% (95%CI: 49.4%-59.4%) were aware of nPEP, and 4.5% (95%CI: 2.9%-6.2%) have used its. 35.9% (95%CI: 31.1%-40.7%) expressed interest in taking nPEP if needed. Among the reasons for not being willing to take nPEP, 68.9% (244/354) were never heard of nPEP, and 24.6% (87/354) were a fluke mentality. The multivariate logistic analysis results showed that the willingness of nPEP awareness of MSM was related to the group aged 25-39 years old (aOR=1.80, 95%CI: 1.01-3.20), knowing a group of HIV prevention knowledge (aOR=2.43, 95%CI: 1.52-3.90), group of consistent condom use in anal sex in the past half of year (aOR=1.76, 95%CI: 1.11-2.79). Conclusions: The use rate of nPEP among MSM in Beijing was low, and the willingness to use in the future also needs to be improved. The training of social organizations should be strengthened to improve the role of peer education in promoting nPEP.

Abstract
Background: Intravenous thrombolysis is the preferred clinical treatment for ultra-early (<4.5 h) ischemic stroke. However, whether intravenous thrombolysis should be used in patients with mild stroke remains controversial. This study reports a systematic review and meta-analysis of the efficacy and safety of intravenous thrombolysis in acute mild stroke.
Methods: The PubMed, Cochrane Library, MEDLINE, Embase and CBM disc databases were searched for studies on intravenous thrombolysis versus nonthrombolysis in acute mild stroke. All studies published in English prior to March 2022 were retrieved. The studies were screened and selected based on the inclusion and exclusion criteria. Then, the data were extracted and recorded by trained researchers. RevMan 5.4 statistical software was used to analyze the data on the efficacy (mRS score, stroke recurrence rate and mortality at 90 days) and safety (intracranial hemorrhage, symptomatic intracranial hemorrhage) of the patients with acute mild stroke in the intravenous thrombolysis and nonthrombolysis groups.
Results: A total of 14 high-quality studies containing 86,063 patients with acute mild stroke (8,824 in the intravenous thrombolysis group; 77,239 in the nonthrombolysis group) were included in this meta-analysis. The meta-analysis results were as follows: (1) Efficacy: There were significant differences in mRS scores of 0~1 and 0~2 between the intravenous thrombolysis and nonthrombolysis groups (mRS 0-1, OR= 1.53, 95% CI: 1.31~1.79, Z=5.40, P <0.00001; mRS 0-2, OR= 1.33, 95% CI: 1.07~1.65, Z=2.59, P =0.01). (2) Safety: There was no significant difference in the recurrence rate of stroke or mortality between the two groups ( recurrence rate, OR= 0.62, 95% CI: 0.35~1.08, Z=1.68, P =0.09; mortality, OR=0.89, 95% CI: 0.45~1.77, Z=0.33, P =0.74). There were more patients with intracranial hemorrhage in intravenous thrombolysis group than in nonthrombolysis group (asymptomatic intracranial hemorrhage, OR= 2.39, 95% CI:1.19~4.80, Z=2.45, P =0.01; symptomatic intracranial hemorrhage, OR= 7.65, 95% CI:3.07~19.05, Z=4.37, P <0.0001).
Conclusion: Intravenous thrombolysis significantly improved the functional outcomes but did not reduce mortality at 90 days in patients with acute mild stroke and had a higher risk of intracranial hemorrhage.

Abstract
The East Asian scorpion Buthus martensii Karsch (BmK) is one of the classical traditional Chinese medicines for treating epilepsy for over a thousand years. Neurotoxins purified from BmK venom are considered as the main active ingredients, acting on membrane ion channels. Voltage-gated sodium channels (VGSCs) play a crucial role in the occurrence of epilepsy, which make them become important drug targets for epilepsy. Long chain toxins of BmK, composed of 60-70 amino acid residues, could specifically recognize VGSCs. Among them, α-like neurotoxins, binding to the receptor site-3 of VGSC, induce epilepsy in rodents and can be used to establish seizure models. The β or β-like neurotoxins, binding to the receptor site-4 of VGSC, have significant anticonvulsant effects in epileptic models. This review aims to illuminate the anticonvulsant/convulsant effects of BmK polypeptides by acting on VGSCs, and provide potential frameworks for the anti-epileptic drug-design.

Abstract
Objective: To enhance the early recognition of Prader-Willi syndrome by summarizing the clinical characteristics of Prader-Willi syndrome (PWS) during perinatal period. Methods: Through a nationwide cross-sectional study in the Department of Pediatrics, Peking Union Medical College Hospital, Peking Union Medical College, Chinese Academy of Medical Sciences,226 children diagnosed as PWS by molecular genetics were recruited from September 2019 to March 2020. Clinical data including fetuses Age, birth weight, fetal movement, fetal position, amniotic fluid, mode of bith, crying, muscle tension, feeding, and cryptorchidism were collected to analyze the clinical characteristics of Chinese PWS patients in the perinatal period, and according to the mode of birty, birth weight and genotypes to perform subgroup analysis. The clinical manifestations of different subtypes were statistically analyzed by t test, χ2 test or Mann-Whitney U test. Results: Among the 226 PWS patients, 120 were males, and 106 were females. Among them, 100 (44.2%) patients were small for gestational age. Decreased fetal movement was the most common manifestation 202 cases (89.4%) during pregnancy, and other manifestations included polyhydramnios 71 cases (31.4%) and abnormal fetal position 58 cases (25.7%). One hundred and eighty-five (81.9%) patients were delivered by cesarean section and the frequency of abnormal fetal position was significantly higher (30.8%(57/185) vs. 2.4%(1/41),χ²=14.161,P<0.01). As for abnormal manifestations after birth included hypotonia 221 cases (97.8%),220 cases (97.3%) showing weak crying, 116 cases among the total 120 males patients (96.7%) wanifested with cryptordnildism and 206 feeding difficulties (91.2%). In terms of genetic subtype, most of them (184/226, 81.4%) had a paternal deletion, while maternal age (35±5 vs. 29±5, t=-6.591, P<0.01) and the frequency of polyhydramnios (47.6% (20/42) vs. 27.7% (51/185), χ²=6.286, P=0.012) were significantly higher in the non-deletion group. Conclusions: The main manifestations of PWS patients during the perinatal period are hypotonia, weak crying, feeding difficulties, decreased fetal movement, cryptorchidism and those patients are more likely to be born by cesarean section. In newborns with these characteristics, pediatricians should be aware of the possibility of PWS. In terms of the relationship between genotypes and phenotypes, polyhydramnios is more frequently observed in the non-deletion group.

Abstract
Objective: To explore the self-conscious health status and related influencing factors of greenhouse agricultural workers in Beijing suburb, so as to provide scientific basis for developing strategies to improve and promote the occupational health conditions of those workers. Methods: According to the production characteristics and scale of the main agricultural districts or counties in the suburb of Beijing, 182 agricultural production personnel were randomly selected to investigate the general situation, occupational situation and self-conscious health status during June 2018 to December 2019. The relevant factors which may affect the self-conscious health conditions were also analyzed by statistical methods. Results: The detection or reported rate of self-conscious health problems was 51.6% (94/182) , among which 29.1% (53/182) workers reported musculoskeletal disorder diseases and 21.4% (39/182) workers reported nervous system diseases. And the self-conscious health status of greenhouse agricultural workers were statistically different in household registration, gender, marital status, working years, mixing or spraying pesticides, smoking or eating in the greenhouse (P<0.05) . Moreover, gender, mixing or spraying pesticide, eating and smoking behavior in the workplace all had an impact on the risk of self-conscious health status of greenhouse agricultural workers (P< 0.05) . Specifically, male is the protective factor to reduce the occurrence of self-conscious symptoms of greenhouse agricultural workers (OR=0.447, 95%CI: 0.234~0.852) , while mixing or spraying pesticides and smoking or eating behaviors in the workplace are the risk factors (OR=1.055, 2.524; 95%CI: 0.503~2.210, 1.107~5.755) . Conclusion: Reducing pesticide use from the source thus minimize related exposure opportunities, strengthening occupational health education thus foster good hygienic habits and improve individual protection consciousness are of great significance for the health protection of greenhouse agricultural workers in Beijing suburb.

Abstract
Understanding the relationship between land use and water quality at different scales is essential in the restoration and protection of water quality. On March 2014, we collected 97 samples in highly urbanized Taihu Basin and analyzed their water quality characteristics. Spatial differences in water quality were evident in sub-basins. The Hu Xi zone with the largest forest area had the best water quality among all the sub-basins. The correlation analysis indicated that the proportions of forest and construction land were significantly associated with multiple water quality variables from buffer to sub-basin scale. Farmland was significantly related to NO3-N at the sub-basin scale. The impact of landscape metrics at the sub-basin was insignificant. Forest and construction land in the 1-2 km buffer zone appeared to have a greater influence on the water quality than the buffers with smaller distance. These results are beneficial toward the understanding of water quality status in highly urbanized watersheds and provide a reference for water quality conservation and land use management in the future.

Abstract
Objective: To investigate the value of sedation in colonoscopy. Methods: A retrospective cohort study of colonoscopy procedures was performed in our institution. Inclusion criteria: (1) colonoscopy procedures were performed by well-trained gastrointestinal surgeons our institution; (2) medical records were complete and colonoscopy was documented properly by notes, videos, photographs, and traceable pathological reports. Those with incomplete records or performed in other institution were excluded. According to above criteria, clinical data of 49 057 cases of clinic and hospitalization receiving diagnostic or therapeutic colonoscopyat Department of Gastric and Colorectal Surgery, Daping Hospital from July 2007 to February 2017 were collected. Among them, there were 24 638 (50.2%) males and 24 419 females, with mean age of (50.6±14.1) (4 to 98) years. Based on the application of sedation during colonoscopy, patients were divided into the sedation group (39 412 cases, 80.3%) and the non-sedation group (9 645 cases, 19.7%). Clinical characteristics of two groups were compared. Results: The sedation rate increased from 45.6% (369/810) to 94.8% (917/967) from 2007 to 2017. As compared to non-sedation group, a higher proportion of females [51.0% (20 095/39 412) vs. 44.8% (4 324/9 645), χ(2)=117.422, P<0.001] and younger median age (50.0 years vs. 51.0 years, Z=-4.774, P<0.001) were found in the sedation group, whose differences were statistically significant. In all the 9645 cases in the non-sedation group, about 5.5% (534) of them terminated the examination because of unbearable discomfort, including 244 (4.6%) males and 290 (6.7%) females (χ(2)=20.522, P<0.001). Among all the screening population who were ≥50 years old, there was no significant difference in the polyp detection rate (PDR) between the sedation group and the non-sedation group [26.7% (4 737/17 753) vs. 27.4% (1 093/3 984), χ(2)=0.937, P=0.330]. The cecal intubation rate (CIR) in the sedation group was significantly higher than that in the non-sedation group [(85.2% (14 422/16 933) vs. 76.1% (2 803/3 682), χ(2)=180.032, P<0.001]. Five cases in the sedation group developed iatrogenic colonic perforation (ICP), with none in the non-sedation group. Conclusions: The application of sedation in colonoscopy is increasingly popular. Sedation can significantly improve CIR in colonoscopy, while it has no positive influence on PDR. Meanwhile, sedation increases the medical expense and may result in higher ICP rate.

Abstract
The maintenance requirements of net energy and net protein were assumed to represent the most accurate and important values totally for the animal's utilization. The objective of this experiment was to determine the net energy and net protein requirements for maintenance of growing arctic foxes. The experiments was evaluated using regression models estimated from data collected by means of indirect calorimetry, nitrogen balance trials, and digestion and metabolism experiments. Thirty-six growing arctic foxes (3 487 ± 261.7 g) at the age of 85 days were randomly assigned to four groups with 9 animals in each group. Arctic foxes were fed a complete formula diet at four intake levels (100%, or 80%, 60%, and 40% of feed requirements) from 24 July 2017 to 23 September 2017. Arctic foxes in each treatment were kept individually in respiration chambers after 1-d adaptation at day 2 for a 3-d balance trial and then at day 5 followed by a 3-d fasting period. The metabolizable energy intake (MEI), heat production in the fed state (HP), and retained energy (RE) of arctic foxes significantly decreased (P < 0.01) as the feed intake level decreased. Fasting heat production (FHP) of arctic foxes was not influenced by feed intake level (P > 0.05). The metabolizable energy maintenance requirement (MEm) and net energy maintenance requirement (NEm) estimated from the linear relationship between RE and MEI were 230 and 217 kJ/kg of body weight BW0.75/d, respectively. The MEm and NEm estimated by logarithmic regression of HP on MEI were 225 and 209 kJ/kg BW0.75/d, respectively. The net N maintenance requirement (NNm) and net protein maintenance requirement (NPm) estimated from the linear relationship between retained nitrogen (RN) and daily nitrogen intake (NI) were 179.6 mg/kg BW0.75/d and 1.123 g/kg BW0.75/d, respectively. It is concluded that NEm and NPm values obtained fill the net energy and protein requirements shortage, and provide the basic data for establishing the standard of nutrition demand of breeding arctic foxes in China.

Abstract
ABA is important for plant growth and development; however, it also inhibits photosynthesis by regulating the stomatal aperture and ribulose-1,5-bisphosphate carboxylase/oxygenase activity. Noteworthy, this negative effect can be alleviated by antioxidants including ascorbic acid (AsA) and catalase (CAT), but the underlying mechanism remains unclear. Two rice cultivars, Zhefu802 (recurrent parent) and its near-isogenic line, fgl were selected and planted in a greenhouse with 30/24 °C (day/night) under natural sunlight conditions. Compared to fgl, Zhefu802 had significantly lower net photosynthetic rate (PN) and stomatal conductance (Cond) as well as significantly higher ABA and H2O2 contents. However, AsA and CAT increased PN, Cond, and stomatal aperture, which decreased H2O2 and malondialdehyde (MDA) levels. In this process, AsA and CAT significantly increased the ribulose-1,5-bisphosphate carboxylase activity, while they strongly decreased the ribulose-1,5-bisphosphate oxygenase activity, and finally caused an obvious decrease in the ratio of photorespiration (Pr) to PN. Additionally, AsA and CAT significantly increased the expression levels of RbcS and RbcL genes of leaves, while H2O2 significantly decreased them, especially the RbcS gene. In summary, the removal of H2O2 by AsA and CAT can improve the leaf photosynthesis by alleviating the inhibition on the stomatal conductance and ribulose-1,5-bisphosphate carboxylase capacity caused by ABA.

Abstract
Objective: To understand the prevalence, diagnosis and treatment of chronic critical illness (CCI) in China. Methods: The clinical data of 472 adult patients admitted to ICU in 53 hospitals, including basic information, disease-related data, nutrition program, etc., were collected on May 10, 2019, by means of multi-center cross-sectional study. If surgical intervention was needed or the occurrence of the disease was directly related to the surgery, ICU patients were regarded as surgical ICU cases (n=211). In this study, the diagnostic criteria for CCI were: (1) admission to ICU >14 days;(2) combined with persistent organ dysfunction. The prevalence,distribution and treatment of CCI and surgery-related CCI were recorded and analyzed. The Mann-Whitney U test, chi-square test or Fisher exact test were used for comparative analysis. Results: Among the 472 ICU patients from 53 hospitals, 326 were male (69.1%) and 146 were female (30.9%). The prevalence of CCI was 30.7% (145/472). Among 211 surgery-related ICU patients, 57 developed CCI with a prevalence of 27.0%. As compared to non-CCI patients, higher APACHE II score [median (IQR) 13.5 (10.0, 18.3) vs. 11.0 (7.0, 16.0), U=2970.000, P=0.007], higher Charlson comorbidity index [median (IQR) 4.0 (2.0, 7.0) vs. 3.0 (1.0, 5.0), U= 3570.000, P=0.036] and higher ratio of breath dysfunction [68.4% (39/57) vs. 48.1% (74/154), χ(2)=6.939, P=0.008] and renal dysfunction [42.1% (24/57) vs. 18.2% (28/154), χ(2)=12.821, P<0.001] were found in surgery-related CCI patients. While SOFA score, Glasgow coma score and other visceral function were not significantly different between surgery-related CCI and non-CCI patients (all P>0.05). NUTRIC score showed that surgery-related CCI patients had higher nutritional risk [43.9% (25/57) vs. 26.6%(41/154), U=5.750, P=0.016] and higher ratio of mechanical ventilation [66.7% (38/57) vs. 52.3% (79/154), χ(2)=3.977, P=0.046] than non-CCI patients. On the survey day, the daily caloric requirements of 50.2% (106/211) of surgery-related ICU patients were calculated according to the standard adult caloric intake index (104.6 to 125.5 kJ·kg(-1)·d(-1), 1 kJ=0.239 kcal), and the daily caloric requirements of 46.4% (98/211) of patients were calculated by physicians according to the severity of the patient's condition. 60.2% (127/211) of nutritional support therapy was enteral nutrition (including a combination of enteral and parenteral nutrition), while the remaining patients received parenteral nutrition (24.6%, 52/211), simple glucose infusion (9.0%, 19/211), or oral diet (6.2%, 13/211). The target calorie of CCI group was 104.6 (87.9, 125.5) kJ·kg(-1)·d(-1), and the actual calorie intake accounted for 0.98 (0.80, 1.00) of the target calory. In the non-CCI group, the target calorie was 104.6 (87.9, 125.5) kJ·kg(-1)·d(-1), and the actual calorie consumed accounted for 0.91 (0.66, 1.00) of the target calorie. There was no statistically significant difference between two groups (P=0.248, P=0.150). Conclusion: The prevalence of CCI and surgery-related CCI in ICU is high, along with severe complications, respiratory and renal dysfunction and mechanical ventilation. Surgical patients admitted to ICU are at high nutritional risk, and active and correct nutritional support is essential for such patients.

Abstract
Objective: To explore the value of cathepsin S in the bronchoalveolar lavage fluid (BALF) of patients with chronic obstructive pulmonary disease (COPD) in the evaluation of pulmonary function and CT phenotypes. Method: From April 2014 to April 2017, 46 patients with stable COPD were enrolled, and 29 healthy volunteers served as the control group. The patients were divided into 4 subgroups: GOLD Ⅰ(n=12), GOLD Ⅱ(n=6), GOLD Ⅲ(n=14), GOLD Ⅳ(n=14). The levels of cathepsin S and IFN-γ in BALF were determined by enzyme-linked immunosorbent assay (ELISA). The percentage ratio of low attenuation area to total lung area (LAA%), two times the ratio of airway wall thickness to outer diameter(2T/D), and the ratio of wall area to total cross-sectional area (WA) were measured by HRCT. Results: There were significant differences in the levels of cathepsin S in BALF between the groups (F=6.639, P=0.000). BALF cathepsin S levels were as follows: GOLD Ⅳ grou P>GOLD Ⅲ grou P>GOLD Ⅱ grou P>GOLD group Ⅰ >healthy control group (P value were all<0.05); LAA grade 3>LAA grade 2>LAA grade 1>LAA grade 0 (P value were all<0.05). Correlation analysis showed that BALF cathepsin S levels were correlated negatively with FEV(1)/FVC, FEV(1)% predicted, and DLCO% (r value was -0.065、-0.576、-0.392, respectively, P value were all<0.05), and but positively with RV/TLC%, LAA%, 2T/D, WA and IFN-γ(r value was 0.695, 0.497, 0.142, 0.309, 0.148, respectively, P value were all<0.05). Conclusion: The levels of cathepsin S were associated with the degree of airflow limitation and emphysema phenotype in COPD.

Abstract
Mulberry leaf was first recorded in the Shennong Bencao Jing(The Classic of Herbal Medicine)《》 on the list of drugs affixed, and first separate recorded in the Bencao Shiyi(Supplement to Materia Medica)《》. By checking Chinese herbs' literature of the harvest processing and application of mulberry leaves, we found that Mulberry leaves can be harvested in Summer and autumn before the Qing dynasty, but from Qing dynasty to present, those harvested in autumn and winter, which were called frost mulberry leaves or winter mulberry leaves, were seen as better. Before the Republic of China, mulberry leaves were dried in shade or on the fire, after that, they were dried in the sun. It can be found that the harvest processing of mulberry leaves was changing as time went on. The clinical application of mulberry leaves had multiplicity, depending on different picking time and different processing method. It is suggested that research of mulberry leaves on chemistry and pharmacology of picking time, processing method can result in new scientifically clinical application.

Abstract
The early-stage diagnosis and treatment for the recurrence of larynx carcinoma needs further investigation. Mesenchyme homeobox 2 (MEOX2) was speculated as a novel suppressor gene in larynx carcinoma in our study, the molecular mechanism was studied. Real-time quantitative PCR (RT-qPCR) and Western blot were used to detect mRNA and protein levels of MEOX2 in laryngeal cancer tissues and cells (Hep-2, TU212, AMC-NH-8 and TU686 cells), and also apoptosis and phosphoinositide 3-kinase (PI3K)/protein kinase (Akt) related factors in TU212 cells transfected with MEOX2. Cell counting kit-8 (CCK8) assay and Annexin-Ⅴ/PI staining assay were conducted to determine cell viability and apoptosis rates respectively.46 patients with larynx carcinoma were involved in this study. The expression of MEOX2 was lower in larynx carcinoma tissues than normal tissues, correlated with clinical stages, differentiated degrees, and survival times. The expression of MEOX2 was the lowest among those laryngeal cancer cells, and was chosen to be transfected with MEOX2 in the following study. Over-expression of MEOX2 inhibited cell viability and promoted apoptosis of TU212 cells, via increasing the expression levels of Caspase-3, and decreasing levels of C-Myc, XIAP, PI3K p110α, PI3K p110β, PI3K class III and p-Akt. In summary, the expression levels of MEOX2 were inhibited in larynx carcinoma than normal tissues, correlated with the progression of the cancer. Over-expression of MEOX2 in laryngeal cancer cells inhibited cell viability and promoted apoptosis, via regulating apoptosis and PI3K/Akt pathway related factors. It would provide evidence for MEOX2 to be used as a therapeutical gene in larynx carcinoma.

Abstract
Jixuecao was first recorded in the Shennong bencaojing. The variety of plant referred to is undefined because of a lack of detailed description in the medical books of the Han and Tang dynasties. From the Song dynasty to the Republican period Jixuecao refers to Glechoma longituba (Nakai) Kupr. The name was also recorded as Jinqiancao instead of Jixuecao in the Bencao gangmu shiyi from the Qing dynasty to the Republican period, though it refers to the same plant. In recent times, Jixuecao has evolved to refer to Centella asiatica (L.) Urb, Jinqiancao now refers to Lysimachia christinae Hance, while G. longituba (Nakai) Kupr. is now called Lianqiancao. It is thus determined that G. longituba (Nakai) Kupr. alone is unequivocally the original plant referred to as Jixuecao, and has the longest medicinal history.

Abstract
Objective: To investigate the relationship between serum secreted frizzled-related protein 5(sfrp5) levels, insulin resistance, and airway inflammation in patients with chronic obstructive pulmonary disease(COPD). Method: A total of 178 COPD patients visiting our respiratory outpatient clinic from February 2015 to January 2017 were enrolled, and 99 healthy control subjects from the same time period were selected. Serum sfrp5 levels were compared between the 2 groups. Serum sfrp5 and inflammatory cytokines in induced sputum were observed in the 4 subgroups: insulin resistant COPD group [homeostasis model assessment of insulin resistance (HOMA-IR)≥2.29], non-insulin resistant COPD group, non-COPD insulin resistant group, and healthy control group. Results: Serum sfrp5 levels were found to be significantly higher in the COPD group as compared to the healthy control group (t=-14.29, P<0.001). Serum sfrp5 levels in the insulin resistant COPD group [(8±3)ng/ml] were significantly lower than that of the non-insulin resistant COPD group [(10±5)ng/ml], non-COPD insulin resistant group [(13±3)ng/ml], and normal control group [(14±4)ng/ml, F=35.85, P<0.01]. The insulin resistant COPD group had higher levels of In(Homa-IR), as well as tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in induced sputum as compared to the non-insulin resistant COPD group, non-COPD insulin resistant group, and healthy control group (F values were 64.968, 41.40, 64.15, respectively, P value <0.01 for all items). The non-insulin resistant COPD group had higher levels of In(HOMA-IR) as well as TNF-α and IL-6 in induced sputum as compared to the non-COPD insulin resistant group and healthy control group. FEV(1)/FVC and FEV(1)% predicted were significantly lower in the insulin resistant COPD group as compared to those of non-insulin resistant COPD group and non-COPD insulin resistant group, and healthy control group (F values were 2.481 and 8.37, respectively, P value<0.05 for all items). FEV(1)/FVC and FEV(1)% predicted were significantly lower in the non-insulin resistant COPD group as compared to those of the healthy control group and non-COPD insulin-resistant group. Serum sfrp5 levels were positively correlated to FEV(1)/FVC and FEV(1) predicted (r values were 0.466 and 0.412, respectively; P values were <0.001 and 0.007, respectively) and inversely correlated to In(HOMA-IR) and TNF-α and IL-6 in induced sputum (r values were -0.304, -0.459, -0.517, respectively; P values were <0.001, 0.002, <0.001, respectively). BMI, ln(HOMA-IR), and IL-6 in induced sputum were independent related factors (r(2) values were 0.286, 0.176, 14.69, respectively; P values were <0.01 for all items) Conclusion: Sfrp5 may be concurrently associated with COPD and insulin resistance; insulin resistance may be associated with airway inflammation and airflow limitation. Sfrp5 may be involved in the development of COPD and may be the key link by which insulin resistance exerts its effects on airway inflammation.

Abstract
The hybrid grouper, Epinephelus fuscoguttatus (♀) × Epinephelus lanceolatus (♂), is a newly bred cultivated marine fish species of high economic value. However, a skin ulcer disease with high mortality has occurred, and the responsible pathogen remains unknown. In this study, we summarized the epidemic status and external signs of this disease. We screened potential pathogens and finally isolated one bacterial strain ML01 from affected fish. We subjected healthy juvenile hybrid groupers to bacterial challenge tests with the isolate by immersion, immersion after dermal abrasion and intraperitoneal injection, respectively. Within 14 days post-infection, the isolate ML01 caused mass mortality of juveniles infected via immersion after dermal abrasion or intraperitoneal injection. Diseased juveniles displayed obvious signs of skin ulcers. The median lethal dose of ML01 by intraperitoneal injection was 1.10 × 105 colony-forming units. ML01 was identified as Vibrio harveyi by bacterial morphology, analytical profile index identification, 16S rDNA sequencing and multilocus sequence analysis. Antibiotic susceptibility tests showed that ML01 was sensitive to ceftriaxone, doxycycline and minocycline. The results of this study suggest that V. harveyi is the causal agent of skin ulcer disease in juvenile hybrid groupers, thus providing a basis for effective control and prevention of this disease.

Abstract
By sorting out the literature on materiamedica, it is found that medicinal history of ClinopodiumHerba is rather long which can be traced back to caoxuejiein Lüchan yan ben cao (Mountainous Materia Medica) with definite efficacy and usage; it is generally believed that the original plant of ClinopodiumHerba is Clinopodiumpolycephalum (Vaniot) C. Y. Wu et Hsuan and C. chinensis (Benth.) O. Kuntze are two separate species, also some scholarsclaim that C. polycephalum and C. chinensisare the same plant. But I think C. polycephalum is the main origin of ClinopodiumHerba, and the relationship of C. polycephalum and C. chinensis maybe a species and its variety.

Abstract
The transcriptomes of salt-stressed and unstressed Betula kirghisorum plants were analyzed using high throughput sequencing technology. A total of 52,239,804 and 51,772,998 clean reads were obtained from the two libraries, respectively, and de novo assembled into 60,545 all-unigenes. A total of 39,997 unigenes were annotated using public databases. Overall, 7206 genes were differentially expressed in unigenes and were involved in 127 pathways. Thirteen transcription factor families were identified in B. kirghisorum, including GRAS proteins, which are plant-specific transcription factors. By using bioinformatic methods to predict and analyze physicochemical properties, structural data were obtained on the 19 potential GRAS proteins. The results revealed that these proteins are hydrophilic, with significant differences in their length and molecular weight. The main secondary structures were alpha helices and random coils. BkGRAS proteins possess typical GRAS domains: LHR I; VHIID motif; LHR II; PFYRE motif; and SAW motif. In the majority of BkGRAS proteins, AGG, AGA, UCU, GCU, GGG, CCA, GUU, GUG, AUU, GAU, and AAG codons were used preferentially. Aside from the BkGRAS17 gene (relative synonymous codon usage (RSCU) = 1.20), usage of the UUA codon by other BkGRAS genes was low (RSCU < 1.0). The effective number of codons showed that BkGRAS genes have low codon bias. Subcellular localization analysis that predicted these proteins are found in the nucleus, cytoplasm, or chloroplast. BkGRAS proteins were divided into six subfamilies: SCR, LISCL, SCL3, DELLA, HAM, and PAT1. These results provide important information for the further functional study of GRAS genes in B. kirghisorum.

Abstract
Herba Schizonepetae was firstly recorded in the Sheng nong ben caojing (Shennong's Materia Medica) with the title Jiasu. It could be sure that the original plant of Jiasu is Ocimumbasilicum L. ofLabiatae based on the record of Jiasu's name, morphology, edible property before the Song Dynasty. Beginning from the Ben cao tu jing (Illustrated Classic of Materia Medica) in the Song Dynasty, the source of this drug evolved as SchizonepetatenuisfoliaBriq. ofLabiatae, and it has been in use until now. Hence, the sources of Jiasu should be both O. basilicum L. and the co-existence of S. tenuisfolia Briq in the Qing Dynasty. It is claimed that the hometowns of those herb writers who considered the source ofOcimumbasilicum L. to be the producing areas of cultivation of the edible Ocimumbasilicum L. It was found that the source of Jiasu recorded in the Sheng nong ben cao jing should be O. basilicum L. , hence, it is suggested the title Jiasu should be recorded for the source of O. basilicum L, and the original plant of Herba Schizonepetae was Schizonepetatenuisfolia Briq. of Labiatae, and this medicine should be separately recorded. In fact, Jiasu and Herba Schizonepetae were two different kinds of medicines.

Abstract
GRAS proteins are plant-specific transcription factors that are involved in the regulation of root and shoot growth. Here, we cloned BkGRAS2 from Betula kirghisorum (abbreviated to Bk) and analyzed the physicochemical properties and expression pattern of the encoded protein. BkGRAS2 had an open reading frame of 1614 bp encoding 537 amino acid residues. The deduced BkGRAS2 protein was hydrophilic, and it contained highly conserved VHIID and SAW motifs. BkGRAS1 and BkGRAS2 showed considerable sequence similarities. An expression analysis indicated that BkGRAS2 was expressed in root, stem, and leaf, with the highest level in the leaf. Expression of BkGRAS2 was increased following stress treatment with 0.6% NaHCO3. Transient expression analysis of GFP-BkGRAS2 in onion epidermal cells revealed that the BkGRAS2 protein was localized in the cytoplasm, but could also be detected in the nucleus. Our study provides the basis for future research on the role of the GRAS gene family in B. kirghisorum.

Abstract
The study was conducted to investigate the effect of dietary manganese (Mn) on reproductive performance of female Ussuri raccoon dogs (Nyctereutes procyonoides) during the breeding season. Healthy female Ussuri raccoon dogs (n=72) were randomly divided into six groups of twelve each. The six experimental diets were formulated to contain graded amounts of Mn (0, 40, 80, 120, 200 and 400mg/kg of diet; Groups A through F, respectively). Litter size of Group D was greater than that of Groups A, B, C and E (P<0.05), with Group E having the smallest litter size. Values of number born alive were affected by different amounts of organic Mn. Number of pups born alive in Group D was greater than that of Groups B, C, E and F (P<0.05). Number of pups weaned alive for Group D was greater than that of Groups A, B, C and E (P<0.05). Mn supplementation of the control diet (containing 24.32 mg/kg from raw materials) with 120 mg/kg of Mn was adequate for female Ussuri raccoon dogs during the breeding season, based on positive effects of reproduction performance.

Abstract
Two experiments were conducted to study the effects of dietary manganese levels on growth performance, nutrients digestibility, and N balance of minks during growing period. In experiment 1, 75 healthy male minks (60 days old) were selected and randomly divided into five groups with different types of diet. The diet was supplemented with 0 (control), 50, 100, 300, and 600 ppm of manganese as MnSO4 of dry matter (DM) in basic diet, respectively. From early July to middle September, the results showed that the final body weights of minks were significantly affected by diets (P < 0.05). Average daily gains (ADG) were significantly higher in the 300-ppm manganese group than those in other groups. The ratio of feed to body weight gain (F/G) was significantly affected by manganese level (P < 0.05). In experiment 2, 45 male minks (75 days old) with the same body weight were selected from each group of experiment 1 to carry out the nutrient digestion and N-balance tests which lasted for 4 days for the collection of the feces and urine, and the diets and treatment codes were same as in experiment 1. The results showed that no significant differences were found in DM, crude protein (CP), and crude carbohydrate (CC) digestibility among all groups (P > 0.05), but ether extract (EE) and gross energy (GE) digestibility were all the highest in the 300-ppm group. N intake and fecal N were similar among all groups (P > 0.05). Urinary N was lower in the 300-ppm group; in contrast, N retention was higher in this group (P < 0.05). In conclusion of experiment 1 and experiment 2, the diet supplemented with 300 ppm of manganese (as manganese sulfate) could improve the growth performance and increase the EE and GE digestibility of mink during the growing period and moreover reduce the nitrogen emissions to the environment, and the optimal total manganese level in mink's diet was 409.16 in DM during the growing period.

Abstract
The Chinese dwarf banana (Ensete lasiocarpum) is one of the ornamental bananas that belongs to Musaceae family. The plant is native to the southwestern China, where it grows semi-wild in the mountains between 1,500 and 2,500 m above sea level. During July 2011, a leaf spot disease on this plant was observed in the campus and parks in Kunming, Yunnan Province. The incidence level was about 22%, mainly on the old leaves. The leaf symptoms were irregular spots with gray to off-white centers surrounded by dark brown margins, and usually also surrounded by chlorotic halos. Leaf tissues (3 × 5 mm), cut from the margins of lesions, were surface-disinfected (95% ethanol for 3 min, 0.1% HgCl2 for 2 min, rinsed three times with sterile water), plated on potato sucrose agar (PSA), and incubated at 26°C under natural lights. The same fungus was consistently isolated from the diseased leaves. Colonies of white-to-dark gray mycelia formed on PSA that were black on the underside. The colonies were further identified as Alternaria sp. based on the dark brown, obclavate to obpyriform catenulate conidia with longitudinal and transverse septa tapering to a prominent beak attached in chains on a simple and short conidiophore (2). Conidia were 5.26 to 30.26 μm long and 3.95 to 15.79 μm wide, averaging 10.21 (±3.17) × 20.02 (±5.75) μm (n = 50), with a beak length of 0 to 7.89 μm, and had 3 to 8 transverse and 0 to 3 longitudinal septa. PCR amplification was carried out by utilizing universal rDNA-ITS primer pair ITS4/ITS5 (1). The ITS region of isolate DY1 (GenBank Accession No. KF516556) was 572 bp in length. BLAST search revealed 99% identity with two Alternaria alternata isolates (JF440581.1 and GQ121322.2). Phylogenetic analysis (MEGA 5.1) using the neighbor-joining algorithm placed the isolate in a well-supported cluster with other A. alternata isolates. The pathogen was identified as A. alternate (Fr.:Fr.) Keissler based on the morphological characteristics and rDNA-ITS sequence analysis. To confirm pathogenicity, Koch's postulates were performed on detached leaves of E. lasiocarpum inoculated with mycelial plugs with ddH2O and agar plugs as a control. Leaf spots identical to those observed in the field developed in 9 days on the inoculated leaves but not on the control. The inoculation assay used three leaves, totaling 72 spots for control and 36 spots for inoculation. The experiments were repeated once. A. alternata was consistently re-isolated from the inoculated leaves. The symptom developed easier with wounds. To our knowledge, this is the first report of E. lasiocarpum leaf spot disease caused by A. alternata in China and the world. References: (1) T. J. White et al.

Abstract
OBJECTIVES The aim of this study was to explore mechanisms by which salvianolic acid A (SAA) revealed its anti-inflammatory activity, in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. MATERIALS AND METHODS Nitric oxide (NO) concentration was determined by the Griess reaction and cell viability was assessed by MTT assay. Interleukin-6, TNFα and interleukin-1β were determined by ELISA. The RAW264.7 cells were transfected with siRNA against p38 or HO-1. Expressions of COX-2, inducible NO synthase (iNOS), NF-κB, HO-1, p-p38 and phosphorylation of IκB kinase α/β were detected by western blotting. Potential targets of SAA were analysed by homology modelling, target prediction, protein-protein interaction prediction and docking studies. RESULTS Salvianolic acid A suppressed LPS-triggered production of NO, TNFα and Interleukin-6. It also reduced protein expression of inducible NO synthase and COX-2, and reduced translocation of NF-κB to nuclei. Moreover, SAA promoted expression of phosphorylated p38, and downstream HO-1. Zn (II) protoporphyrin IX, a specific inhibitor of HO-1, or siRNA against HO-1 could effectively increase transfer of NF-κB. SAA was predicted to target amyloid-beta protein-like protein and arachidonate 5-lipoxygenase, that could regulate p38 and HO-1. CONCLUSIONS In silico analysis and experimental validation together demonstrated that SAA exhibited its anti-inflammatory effect via the p38-HO-1 pathway in LPS-stimulated RAW264.7 cells, reduced transfer of NF-κB to the nuclei and thus reduced production of inflammatory mediators.

Abstract
Chinese bean tree, Catalpa fargesii f. duciouxii (Dode) Gilmour, is an ornamental arbor plant. Its roots, leaves, and flowers have long been used for medicinal purposes in China. During July 2010, severe outbreaks of leaf spot disease on this plant occurred in Kunming, Yunnan Province. The disease incidence was greater than 90%. The symptoms on leaves began as dark brown lesions surrounded by chlorotic halos, and later became larger, round or irregular spots with gray to off-white centers surrounded by dark brown margins. Leaf tissues (3 × 3 mm), cut from the margins of lesions, were surface disinfected in 0.1% HgCl2 solution for 3 min, rinsed three times in sterile water, plated on potato dextrose agar (PDA), and incubated at 28°C. The same fungus was consistently isolated from the diseased leaves. Colonies of white-to-dark gray mycelia formed on PDA, and were slightly brown on the underside of the colony. The hyphae were achromatic, branching, septate, and 4.59 (±1.38) μm in diameter on average. Perithecia were brown to black, globose in shape, and 275.9 to 379.3 × 245.3 to 344.8 μm. Asci that formed after 3 to 4 weeks in culture were eight-spored, clavate to cylindrical. The ascospores were fusiform, slightly curved, unicellular and hyaline, and 13.05 to 24.03 × 10.68 to 16.02 μm. PCR amplification was carried out by utilizing universal rDNA-ITS primer pair ITS4/ITS5 (2). Sequencing of the PCR products of DQ1 (GenBank Accession No. JN165746) revealed 99% similarity (100% coverage) with Colletotrichum gloeosporioides isolates (GenBank Accession No. FJ456938.1, No. EU326190.1, No. DQ682572.1, and No. AY423474.1). Phylogenetic analyses (MEGA 4.1) using the neighbor-joining (NJ) algorithm placed the isolate in a well-supported cluster (>90% bootstrap value based on 1,000 replicates) with other C. gloeosporioides isolates. The pathogen was identified as C. gloeosporioides (Penz.) Penz. & Sacc. (teleomorph Glomerella cingulata (Stoneman) Spauld & H. Schrenk) based on the morphological characteristics and rDNA-ITS sequence analysis (1). To confirm pathogenicity, Koch's postulates were performed on detached leaves of C. fargesii f. duciouxii, inoculated with a solution of 1.0 × 106 conidia per ml. Symptoms similar to the original ones started to appear after 10 days, while untreated leaves remained healthy. The inoculation assay used three leaves for untreated and six leaves for treated. The experiments were repeated once. C. gloeosporioides was consistently reisolated from the diseased tissue. C. gloeosporioides is distributed worldwide causing anthracnose on a wide variety of plants (3). To the best of our knowledge, this is the first report of C. gloeosporioides causing leaf spots on C. fargesii f. duciouxii in China. References: (1) B. C. Sutton.

Abstract
The cell biological properties of collagen, gelatin and collagen hydrolysate (<15 000 Da) were studied using murine keratinocytes. Keratinocyte culture experiments demonstrated that only collagen had significant effects on cell attachment and proliferation, but the results of cells cultured on gelatin and collagen hydrolysate showed the rates of adhesion and proliferation were similar to those of cells cultured on plastic as a control. It is concluded that collagen has better physiological effects than those of gelatin and collagen hydrolysate as skin-care cosmetic materials.

Abstract
This randomized, double-blind, parallel-design study compared the short-term effects of rosuvastatin and atorvastatin on serum lipids and markers of inflammation and endothelial function in patients with stable atherosclerosis. Patients received either 10 mg/day rosuvastatin ( n = 18) or 20 mg/day atorvastatin ( n = 18), orally, for 4 weeks. Serum lipids, high-sensitivity C-reactive protein (hsCRP), Rho-associated coiled-coil containing protein kinase (ROCK) activity and flow-mediated dilation (FMD) of the brachial artery were assessed before and after therapy. Both statins produced significant reductions in total cholesterol, low-density lipoprotein cholesterol (LDL-C), triglyceride and hsCRP levels, and significant increases in FMD. Both statins significantly reduced ROCK activity and inhibition was significantly greater with rosuvastatin. There was no correlation between ROCK activity and LDL-C level in either group. There was a significant correlation between ROCK activity and FMD for both statins, but no correlations between FMD and LDL-C or hsCRP levels. Short-term treatment with either rosuvastatin or atorvastatin inhibits ROCK activity independent of cholesterol reduction, and improves endothelium dysfunction in patients with atherosclerosis.

Abstract
AIMS To differentiate pathogenic and nonpathogenic Edwardsiella tarda strains based on the detection of type III secretion system (T3SS) gene using polymerase chain reaction (PCR). METHODS AND RESULTS Primers were designed to amplify Edw. tarda T3SS component gene esaV, catalase gene katB, haemolysin gene hlyA and 16S rRNA gene as an internal positive control. Genomic DNAs were extracted using a commercial isolation kit from 36 Edw. tarda strains consisting of 18 pathogenic and 18 nonpathogenic strains, and 50 ng of each DNA was used as the template for PCR amplification. PCR was performed with a thermocycler (TaKaRa TP600) in a 25-μl volume. Products of esaV were detected in all pathogenic strains, but not in nonpathogenic strains; katB was detected in all pathogenic strains and one of nonpathogenic strains; hlyA was not detected in any strains. CONCLUSIONS The detection of esaV gene can be used for the assessment of pathogenic Edw. tarda strains. SIGNIFICANCE AND IMPACT OF THE STUDY The strategy using T3SS gene as the virulence indicator provides a useful tool for the clinical assessment of pathogenic Edw. tarda strains and prediction of edwardsiellosis risk in fish culture environments.

Abstract
A novel nonionic surfactant- and hydrophilic solvent-stable alkaline serine protease was purified from the culture supernatant of Serratia sp. SYBC H with duckweed as nitrogen source. The molecular mass of the purified protease is about 59 kDa as assayed via SDS-PAGE. The protease is highly active over the pH range between 5.0 and 11.0, with the maximum activity at pH 8.0. It is also fairly active over the temperature range between 30 and 80°C, with the maximum activity at 40°C. The protease activity was substantially stimulated by Mn(2+) and Na(+) (5 mM), up to 837.9 and 134.5% at 40°C, respectively. In addition, Mn(2+) enhanced the thermostability of the protease significantly at 60°C. Over 90% of its initial activity remained even after incubating for 60 min at 40°C in 50% (v/v) hydrophilic organic solvents such as DMF, DMSO, acetone and MeOH. The protease retained 81.7, 83.6 and 76.2% of its initial activity in the presence of nonionic surfactants 20% (v/v) Tween 80, 25% (v/v) glycerol and Triton X-100, respectively. The protease is strongly inhibited by PMSF, suggesting that it is a serine protease. Washing experiments revealed that the protease has an excellent ability to remove blood stains.

Abstract
OBJECTIVE To investigate the effects of Yikunning (compound of Chinese traditional Medicine, YKN) on the apoptotic rate and expression of caspase-3 in rat ovaries during perimenopausal period. METHODS Thirty female Wistar rats during perimenopausal period were selected by unforced aging. Then the rats were divided into 3 groups randomly: YKN group, livial control group and aged control group. Ten young female rats were selected as young control group. Intragastric administrations were conducted for 4 weeks once daily continuously. The apoptotic rate in rat ovaries were detected by TUNEL. The expression of caspase-3 mRNA and protein in rat ovaries were detected by RT-PCR and Western blot, respectively. RESULTS The apoptotic rate in rat ovaries in YKN group was lower than that in aged control group, which showed difference between them (P < 0.01). The levels of caspase-3 mRNA and protein in rat ovaries in YKN group were lower than those in aged control group, which showed differences among them (P < 0.01). CONCLUSION YKN can decrease the apoptotic rate and down-regulate the expression of caspase-3 mRNA and protein in rat ovaries of during perimenopausal period. It may be one of the molecular mechanisms of YKN postponed the ovarian failure and cured perimenopausal syndrome.

Abstract
Phytophthora sansomeana E.M. Hansen & Reeser is a newly described species and infects Douglas-fir, alfalfa, and soybean (1). Soybean production is an important part of the local economy in Yili State in Xinjiang Uygur Autonomous Region, northwest China. Unfortunately since 2005, root and stem rot disease has emerged on a number of farms. To identify the causal agent, plant samples with symptoms, including whole plant wilting or yellowing and stunting, were collected from fields during 2005 and 2008. Tissue from the edges of stem lesions was placed on selective lima bean agar (LBA) at 20°C for 3 to 4 days (2,3). Four single zoospore isolates of Phytophthora were obtained and maintained on LBA or 10% V8 juice liquid medium for examination of morphological and physiological characteristics. The colonies on LBA were aerial and rosaceous. The isolates were homothallic, and oogonia and oospores were readily produced in culture after 7 days on LBA plates. Oogonia averaged 38 μm and oospore width ranged from 23 to 48 μm and averaged 31 μm. Antheridia were approximately 15 × 12 μm and predominantly amphigynous in V8 juice. Sporangia were terminal or paragynous on persistent sporangiophores, nonpapillate, ovoid to obpyriform, and measured 52 × 35 μm with an average length/breadth ratio of 1.5. Hyphal swellings were produced in V8 juice 2 days after inoculation. The optimum temperature for growth was approximately 25°C and none occurred at 0 or 35°C. The internal transcribed spacer (ITS) sequence of this Phytophthora species (GenBank FJ966880) agreed 100% with sequences of P. sansomeana isolates deposited in GenBank (GQ853880 and EU925375). Pathogenicity tests were performed by hypocotyl inoculation method (2) using isolate Yili71 and potted soybean cv. Williams. Plants were grown in a growth chamber for 10 days before inoculation in 16-cm-diameter pots (2). Plants were inoculated with 2- × 2-mm plugs of mycelium grown for 4 days on LBA at 25°C, the plugs were adhered to the sides of wounded lower hypocotyls. As controls, plants were inoculated with LBA agar plugs without mycelium (2). Inoculated plants were maintained in a growth chamber at approximately 25°C with a 10-h dark/14-h light cycle and 50% relative humidity and symptom development was monitored daily for 1 week. Wounded stems inoculated with mycelium developed water-soaked lesions, which were similar to those seen on naturally infected plants. A Phytophthora sp. was reisolated from the margins of expanding lesions on wounded stems. To our knowledge, this is the first report of P. sansomeana infection of soybean in China and the threat it may pose to soybean production is unclear. References: (1) E. M. Hansen et al.

Abstract
Verticillium dahliae Kleb. causes Verticillium wilt in large numbers of crops all over the world. Common symptoms caused by the pathogen include yellowing, wilting of leaves, and discoloration in vascular tissue of the stem. In June 2007, symptoms of Verticillium wilt were observed in a grapevine (Vitis vinifera) field in the Shihezi Region of Xinjiang. To isolate the pathogen, stem segments (0.5 cm long) were surface sterilized with 1% HgCl2 for 1 min and then dipped in 70% ethanol for 10 s. The sterilized tissues were rinsed with sterile water and incubated in the dark for 7 days at 25°C on potato dextrose agar (PDA) medium. The fungus growing from the diseased tissue showed dark colonies that produced verticillate conidiophores with two to three layers with colorless, ovoid, unicellular conidia and small, black microsclerotia, which are characteristics of V. dahliae (3). To confirm its identity, ribosomal DNA fragments (regions ITS1, 5.8S rDNA, and ITS4) were PCR amplified with primer pair ITS1/ITS4 (4) and sequenced (GenBank Accession No. FJ475122). Sequential analysis revealed that the rDNA region of the fungus isolated from grapevine was identical to that of a Greek strain of V. dahliae (GenBank Accession No. AF104926). Furthermore, the specific fragment (1,500 bp) of nondefoliating pathotype of V. dahliae (1) was PCR amplified from 24 grapevine isolates of V. dahliae collected in Xinjiang, indicating that the V. dahliae pathogen from Xinjiang is a nondefoliating pathotype. To verify the causal role of the isolated fungus, pathogenicity assays were conducted on 1-year-old seedlings of the Centennial seedless cultivar. Trimmed roots were submerged in a conidial suspension (1 × 106 conidia/ml) for 30 min and sterile tap water was used as a control. The seedlings were transplanted into a pot containing 2:1 sterile mixture of peat/perlite (vol/vol). Plants were grown in a greenhouse at 25°C. Six Verticillium isolates were found to cause the same symptoms as in fields 50 days after inoculation. V. dahliae was successfully reisolated from the stems of inoculated plants. Control seedlings inoculated in sterile tap water remained healthy. Because grapevine (Vitis vinifera) is an economically important crop for fruit and winemaking material in Xinjiang, Verticillium wilt poses a threat. The disease has been previously reported in the United States (2), but to our knowledge, this is the first report from China. References: (1) E. Pérez Artés et al. Eur. J.

Abstract
In this paper, we describe sex-related health risks among hostesses in two metropolises in China based on data obtained from in-depth interviews. The data show that hostesses, many engaging in commercial sex, are vulnerable to HIV infection, unwanted pregnancies and reproductive tract infections. Nevertheless, many obstacles still are present that hinder them from engaging in safe sex. The findings from our study illustrate the need for targeted interventions in order to improve reproductive health and promote safe sex among this group.
