[Effects of Biochar on Growth and Pollutant Accumulation of Lettuce in Soil Co-contaminated with Tetracycline and Copper].

Through lettuce potting experiments, the effects of different types of biochar (apple branch, corn straw, and modified sorghum straw biochar with phosphoric acid modification) on lettuce growth under tetracycline (TC) and copper (Cu) co-pollution were investigated. The results showed that compared with those under CK, the addition of biochar treatment significantly increased the plant height, root length, shoot fresh weight, and root fresh weight of lettuce (P < 0.05). The addition of different biochars significantly increased the nitrate nitrogen, chlorophyll, and soluble protein content in lettuce physiological indicators to varying degrees, while also significantly decreasing the levels of malondialdehyde, proline content, and catalase activity. The effects of biochar on lettuce physiological indicators were consistent during both the seedling and mature stages. Compared with those in CK, the addition of biochar resulted in varying degrees of reduction in the TC and Cu contents of both the aboveground and underground parts of lettuce. The aboveground TC and Cu levels decreased by 2.49%-92.32% and 12.79%-36.47%, respectively. The underground TC and Cu levels decreased by 12.53%-55.64% and 22.41%-42.29%, respectively. Correlation analysis showed that nitrate nitrogen, chlorophyll, and soluble protein content of lettuce were negatively correlated with TC content, whereas malondialdehyde, proline content, and catalase activity were positively correlated with TC content. The resistance genes of lettuce were positively correlated with TC content (P < 0.05). In general, modified biochar was found to be more effective in improving lettuce growth quality and reducing pollutant accumulation compared to unmodified biochar, with modified sorghum straw biochar showing the best remediation effect.

Effects of Fe(II) concentration on the biosynthesis of schwertmannite by Acidithiobacillus ferrooxidans and the As(III) removal capacity of schwertmannite.

The effect of Fe(II) concentrations on schwertmannite bio-synthesis and the As(III) removal capacity of schwertmannite were investigated in this study. Acidithiobalillus ferrooxidans (A. ferrooxidans) were inoculated into five FeSO4 systems with initial concentrations of 50, 100, 200, 300, and 400 mmol/L, respectively, to bio-synthesize schwertmannite. The Fe(II) of the systems were almost completely oxidised at 48, 72, 120, 168, and 192 h, respectively, and the bio-schwertmannite yield was 1.99, 3.81, 9.36, 12.42, and 21.60 g/L. The results of this study indicate that all minerals harvested from the different systems are schwertmannite. As the initial Fe(II) concentration increases, the effect of the minerals removing As(III) decreases; moreover, the structure and extracellular polymeric substance (EPS) of schwertmannite may regulate the As(III) removal process. The EPS generated by the A. ferrooxidans can absorb As(III). The outcomes of this study provide fresh insights into the bio-synthetic regulation of schwertmannite and play a significant role in treating As-containing groundwater.

Effect of pH regulation on the formation of biogenic schwertmannite driven by Acidithiobacillus ferrooxidans and its arsenic removal ability.

The effect of pH regulation on schwertmannite bio-synthesis and its As removal ability were investigated in this study. The total Fe precipitation efficiency in a conventional schwertmannite bio-synthesis system (CK) reached 26.5%, with a mineral weight of 5.21 g/L and a mineral specific surface area of 3.18 m2/g. The total Fe precipitation efficiency increased to 88.4-95.8%, the mineral weight increased to 17.10-18.62 g/L, and the specific surface area increased to 3.61-90.67 m2/g of five different treatments in which the system pH was continually adjusted to 2.50, 2.70, 2.90, 3.10, and 3.30 every 3 h, respectively. The very small amounts of schwertmannite were transformed to goethite when the system pH was periodically adjusted to 2.90, 3.10 and 3.30. The increased specific surface area of bio-schwertmannite was due to the contribution of mesopores, with most pores having a diameter of 2-20 nm. For actual As-containing groundwater (27.4 µg/L), the As removal rate was 52.9% for bio-schwertmannite collected from the CK system. However, the removal rate of As increased to 92.7-97.8% for minerals which were collected after five adjusted pH treatments. The outcomes of this study provide a fresh insight into the bio-synthesis regulation of schwertmannite, and have great significance for the treatment of As-containing groundwater.

The correlation between preoperative MR imaging features of clear cell renal cell carcinoma and the incidence of metastasis / 实用放射学杂志

Objective To investigate the correlation between preoperative MR imaging features and the incidence of tumor metastasis in clear cell renal cell carcinoma.Methods The clinical and preoperative MR imaging data of 64 patients with clear cell renal cell carcinoma were analyzed retrospectively.According to the occurrence of metastasis,the patients were divided into non-metastasis group(n=42)and metastasis group(n=22).The clinical and imaging features of the two groups were analyzed with univariate analysis and multivariate logistic regression.Results The results of the univariate analysis showed that among the clinical and preoperative MR imaging data,there was no significant difference between the two groups in gender,tumor location and intra-tumoral cystic changes(P>0.05),but the patient's ages,clinical symptoms,tumor sizes,necrosis,capsule breakthrough,low signal nodules in T2WI,venous thrombosis,TNM stages,and Fuhrman grades were significantly different between two groups(P<0.05).Multivariate logistic regression analysis showed that low signal nodules in T2WI was an independent predictor of metastasis of clear cell renal cell carcinoma(P=0.028).Combined with diffusion weighted imaging(DWI)sequence,the average apparent diffusion coefficient(ADC)in related areas was measured.The ADC value of low signal nodules area was(0.541±0.101)×10-3 mm2/s in the metastasis group,and the ADC value of non-low signal nodules area was(0.972±0.113)×10-3 mm2/s(P<0.001).Conclusion The metastasis of clear cell renal cell carcinoma is often accompanied by low signal nodules in T2WI in tumors.Combined with the lower ADC value,they can be used as the characteristic imaging features to effectively evaluate the risk of metastasis of clear cell renal cell carcinoma.

Advances in animal models of chronic heart failure and its applications in traditional Chinese medicine / 中国中药杂志

Chronic heart failure(CHF) is a series of clinical syndromes in which various heart diseases progress to their end stage. Its morbidity and mortality are increasing year by year, which seriously threatens people's life and health. The diseases causing CHF are complex and varied, such as coronary heart disease, hypertension, diabetes, cardiomyopathy and so on. It is of great significance to establish animal models of CHF according to different etiologies to explore the pathogenesis of CHF and develop drugs to prevent and treat CHF induced by different diseases. Therefore, based on the classification of the etiology of CHF, this paper summarizes the animal models of CHF widely used in recent 10 years, and the application of these animal models in traditional Chinese medicine(TCM) research, in order to provide ideas and strategies for studying the pathogenesis and treatment of CHF, and provide ideas for TCM modernization research.

Textual research on Bungarus Parvus / 中国中药杂志

Bungarus Parvus, a precious animal Chinese medicinal material used in clinical practice, is believed to be first recorded in Ying Pian Xin Can published in 1936. This study was carried out to analyze the names, geographical distribution, morphological characteristics, ecological habits, poisonousness, and medicinal parts by consulting ancient Chinese medical books and local chronicles, Chinese Pharmacopeia, different processing standards of trditional Chinese medicine(TCM) decoction pieces, and modern literatures. The results showed that the earliest medicinal record of Bungarus Parvus was traced to 1894. In 1930, this medicinal material was used in the formulation of Annao Pills. The original animal, Bungarus multicinctus, was recorded by the name of "Bojijia" in 1521. The morphological characteristics, ecological habits, and poisonousness of the original animal are the same in ancient and modern records. The geographical distribution is similar between the ancient records and modern documents such as China Medicinal Animal Fauna. The dried body of young B. multicinctus is used as Bungarus Parvus, which lack detailed references. As a matter of fact, it is still inconclusive whether there are differences between young snakes and adult snakes in terms of active ingredients, pharmacological effects, and clinical applications. This study clarified the medicinal history and present situation of Bungarus Parvus. On the basis of the results, it is suggested that systematic comparison on young and adult B. multicinctus should be carried out to provide references for revising the medicinal parts of B. multicinctus.

Pharmacological research progress of five classical prescriptions in treatment of chronic heart failure / 中国中药杂志

Chronic heart failure(CHF) is a comprehensive clinical syndrome caused by multiple factors that result in structural and/or functional abnormalities of the heart, leading to impaired ventricular contraction and/or relaxation functions. This medical condition represents the final stage of various cardiovascular diseases. In the treatment of CHF, multiple clinical studies have demonstrated the benefits of using traditional Chinese medicine(TCM) to control oxidative stress, inflammation, and apoptosis, thereby delaying ventricular remodeling and reducing myocardial fibrosis. In this study, common TCM syndromes in the diagnosis and treatment of CHF in recent years were reviewed and summarized. Five common treatment methods including benefiting Qi and activating blood circulation, enhancing Qi and nourishing Yin, warming Yang for diuresis, eliminating phlegm and dampness, rescuing from collapse by restoring Yang, and corresponding classic prescriptions in prevention and treatment of CHF were concluded under the guidance of TCM syndrome differentiation thinking. Meanwhile, research progress on the modern pharmacological effects of these classic prescriptions was systematically discussed, so as to establish a unique treatment system for CHF by classic prescriptions under the guidance of TCM syndrome differentiation theory and provide innovative diagnosis and treatment strategies for clinical CHF.

Comparison on volatile components between Artemisiae Verlotori Folium and Artemisiae Argyi Folium based on GC-MS and chemometrics / 中国中药杂志

Artemisiae Argyi Folium is commonly used in clinical practice. Artemisiae Verlotori Folium, the dried leaves of Artemisia verlotorum, is often used as a folk substitute for Artemisiae Argyi Folium in Lingnan area. In this study, gas chromatography-triple quadrupole mass spectrometry(GC-MS) was used to detect the volatile oil components of 27 samples of Artemisiae Verlotori Folium and 13 samples of Artemisiae Argyi Folium, and the volatile components were compared between the two species. The internal standard method was combined with multi-reaction monitoring mode(MRM) to determine the content of six major volatile components. Hierarchical clustering analysis(HCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were carried out for the content data. The results showed that the Artemisiae Argyi Folium samples had higher content and more abundant volatile oils than the Artemisiae Verlotori Folium samples. Artemisiae Argyi Folium mainly had the components with lower boiling points, while Artemisiae Verlotori Folium mainly had the components with higher boiling points. Terpenoids were the main volatile components in Artemisiae Verlotori Folium(mainly sesquiterpenoids) and Artemisiae Argyi Folium(monoterpenoids). In addition, Artemisiae Argyi Folium had higher content of oxygen-containing derivatives than Artemisiae Verlotori Folium. Furthermore, the stoichiometric analysis showed that the two species could be distinguished by both HCA and OPLS-DA, indicating that the volatile components of the two were significantly different. This study can provide a scientific basis for the quality evaluation and data support for the local rational application of Artemisiae Verlotori Folium in Lingnan.

Multi-parameter flow cytometry (FCM) was used to detect the expression levels of ROR1 in tumor cells of 209 patients. And then the diagnostic value of ROR1 in CLL patients and its correlation with the genetic and molecular biological abnormalities were analyzed by c2 test and fourfold table assessment.Results:The positive expression rate of ROR1 in CLL patients was significantly higher than that in non-CLL patients (78%>11%, P<0.001); there was no significant difference of ROR1 expression between typical phenotype CLL and atypical phenotype CLL (81%>63%, P>0.05). The positive expression rate of ROR1 in atypical phenotype CLL was significantly higher than that in MCL (63%>21%, P<0.05). Additionally, there was significant difference in detection rate of chromosomal abnormalities between ROR1 +CLL group and ROR1 -CLL group. The detection rate of complex karyotype in ROR1 +CLL group was higher than that in ROR1 -CLL group (34%>14%, P<0.05). The CLL patients over 60 years old had higher ROR1 positive rate ( P<0.05). Conclusions:ROR1 can be helpful in the diagnosis of CLL, especially in the differential diagnosis of atypical phenotype CLL, MCL and other types of B-CLPD. Patients with ROR1 positive expression were older and more likely to detect complex chromosomal karyotypes.

A new method of microglia sorting and functional characteristics of spinal microglia in aged rats / 中国应用生理学杂志

Objective: To establish an improved method of separating microglia from aged rats and to observe the biological characteristics of spinal microglia of aged rats. Methods: Young SD rats (2 months) were used as control group. Single cell suspension of rat microglia were prepared by trypsin, trypsin substitutes or mechanical net rubbing method. Then, by assessing the purity and survival rate of cells, and observing the morphological characteristics and analyzing the inflammatory functional characteristics, we optimized the isolation and purification method of microglia from aged rats (20 months old) , and observed the functional characteristics of spinal microglia in aged rats. Results: The survival rate of cells digested by pancreatic enzyme was low(young rats 83%, aged rats 60%). Although the survival rate of mechanical net rubbing method was higher than that of pancreatic enzyme digest methods (95%), the cell acquisition rate was lower(young rats(0.207±0.020)×106, aged rats(0.243±0.023)×106). Trypsin substitute dissociation combining density gradient centrifugation method was the best way to get abundant, active and higher survival microglia, and the purity reached more than 85%. We used this method to separate microglia from spinal cord of rats. Compared with the young rats, the spinal cord tissue of old rats was larger, the digestive fluid volume was higher, but the digestion time was shorter. Compared with the young rats, the aged rat spinal microglia had larger and rounder cell body, fewer and shorter protrusions, it tended to be activated morphologically, the level of proinflammatory cytokine IL-1β of microglia in aged rats was lower, and the level of antiinflammatory factor IL-10 was higher. Conclusion: The method of trypsin substitute dissociation combined with density gradient centrifugation was successfully established to isolate and purify microglia from spinal cord of rats, the spinal microglia of old rats showed anti-inflammatory phenotype.

Correlation analysis of VHL and Jade-1 gene expression in human renal cell carcinoma.

OBJECTIVE: The aim of this study was to investigate the correlation of von Hippel-Lindau tumor suppressor (VHL) mRNA expression and jade family PHD finger 1 (Jade-1) gene expression in patients with renal cell carcinoma (RCC). Another aim of this study was to analyze the relationship of these two genes with clinicalpathological features of the RCC patients. METHODS: A total of 75 RCC patients who received surgically therapy in our hospital were included. All patients had complete pathological data. The expression of VHL/Jade-1 was determined by real-time polymerase chain reaction (RT-PCR). RESULTS: VHL and Jade-1 were both obviously downregulated in RCC tissues than that of the matched normal tissues, and both negatively correlated with tumor size as well as tumor grade. And we found a fine association of VHL gene expression with Jade-1. CONCLUSION: VHL/Jade-1 exhibited significantly decreased expression in RCC tissues and was closely related to the clinical prognosis of patients. The finding of VHL expression positively correlated with Jade-1 expression shed light and provided crucial evidence on the connection of VHL protein with Wnt/b-catenin pathway.

Effect of Different Stimulating Strength of Electroacupuncture on Gastrointestinal Motility and RhoA/ROCK Signaling in Gastric Antral Smooth Muscle in Diabetic Gastroparesis Rats / 针刺研究

OBJECTIVE: To observe the effect of different strength of electroacupuncture (EA) stimulation on gastrointestinal motility and Ras homolog gene family member (RhoA)/Rho associated coiled-coil forming protein kinase (ROCK) signaling in diabetic gastroparesis (DGP) rats, so as to reveal the underlying mechanisms of EA for improving DGP. METHODS: Sixty SD rats were randomly and equally divided into blank control, DGP model, weak EA, medium EA, and strong EA groups (n＝12 rats in each). The DGP model was established by intraperitoneal injection of streptozotocin (STZ, 55 mmol/kg, 2%) and high-sugar and high-fat fodder feeding for 8 weeks. EA (0.12, 0.24, 0.36 mA, 20 Hz/100 Hz) was applied to "Zusanli" (ST 36), "Sanyinjiao" (SP 6) and "Liangmen" (ST 21) for 20 min, once daily for 15 successive days. Blood glucose levels were measured weekly with blood glucose meter and blood glucose test paper. Fecal phenol red excretion method was used to display gastric emptying and small intestinal propulsion function. The expression of RhoA protein in the gastric antral smooth muscle tissue was detected by immunohistochemistry and Western blot (WB), separately, and that of ROCK, myosin phosphatase target subunit 1 (MYPT 1) and phosphorylated (p)-MYPT 1 proteins in gastric antrum detected by WB. RESULTS: Compared with the blank control group, the gastric emptying rate and small intestine propulsion rate of the model group were significantly decreased (P0.05). CONCLUSION: Electroacupuncture stimulation of ST 36-SP 6-ST 21 at 0.12, 0.24 and 0.36 mA can promote the gastrointestinal motility in DGP rats, which may be associated with its effects in enhancing RhoA/ROCK signaling in the gastric antral smooth muscle at different degrees.
