Abstract:
Nitrobenzene compounds (NBCs) are widely used in the world. It has 40 isomers such as nitrobenzene, dinitrobenzene
and nitrotoluene, that are highly toxic and difficult to degrade and can cause harm to human health in different degrees. At pres⁃
ent, there is no unified standard method and occupational exposure limit for the detection of NBCs in the air. In terms of sampling
medium, solid adsorption tube is mostly used for trapping vapor state NBCs, and filter membrane and solid adsorption tube are
mostly used in series for sampling coexist NBCs in vapor state and aerosol state. In the detection methods, gas chromatography
and liquid chromatography are common, and ultraviolet spectrophotometry, Raman spectroscopy, ion migration spectrometry and
some other rapid response methods and technologies are also used in the detection of NBCs. In the detection of NBCs by gas chro⁃
matography, capillary column separation is commonly used, and the main detectors are flame ionization detector, electron capture
detector and mass spectrometry detector. It is of practical significance to establish a method with high sensitivity, strong practica⁃
bility, convenient operation, and can simultaneously collect and detect a variety of NBCs in different states.

OBJECTIVETo investigate whether homocysteine (Hcy) participates the proliferation of the spontaneously hypertensive rat(SHR) vascular smooth muscle cell (VSMCs) and the molecular mechanism.
METHODSThe rat's arota were removed. The primary SHR VSMCs were isolated and cultured in vitro, then the SHR VSMCs were divided into four groups: (1) control group, (2) Hcy group, (3) 18alpha-glycyrrhetinic acid (GA) group, (4) Hcy + 18alpha-GA group. We detected proliferation of the SHR VSMCs by MTT and flow cytometry. The expression and co-localization of the connexin (Cx) 43 and Cx40 proteins in the SHR VSMCs were deteced by immunofluorescence. The expression of the Cx43 and Cx40 proteins in SHR VSMCs were detected by Western blot. The molecular dye transfer method (scrape dye transfer method) was applied to detect the gap junction function in the SHR VSMCs.
RESULTS(1) The Cx43 and Cx40 proteins expression in the SHR VSMCs were positive, confocal microscopy supported the co-localization of Cx43 and Cx40 in the cytoplasm. (2) The S value deteced by cell cycle and A value detected by MTT in the Hcy group were increased obviously compared with those in the control group (P < 0.05), decreased in 18alpha-GA group (P < 0.05). Compared with the Hcy group, the S and A value in the Hcy + 18alpha-GA group were significantly decreased, respectively (P < 0.05). (3) The expression of Cx43 and Cx40 proteins in Hcy group were increased compared with the control group (P < 0.05), decreased in 18alpha-GA group (P < 0.05). Compared with the Hcy group, the expression of Cx43 and Cx40 proteins in the Hcy + 18alpha-GA group were significantly decreased, respectively (P < 0.05). (4) The function of gap junction detected by scrape dye transfer method in the Hcy group were enhanced compared with the control group (P < 0.05), weakened in the 18alpha-GA group (P < 0.05). Compared with the Hcy group,the function of gap junction in the Hcy + 18alpha-GA group was significantly weakened (P < 0.05).
CONCLUSIONHcy can enhance the function of gap junctional to stimulate the proliferation of SHR VSMCs through the expression of Cx43 and Cx40 proteins promoted.

BACKGROUND AND OBJECTIVEAllogeneic hematopoietic cell transplantation (allo-HSCT) is a potent procedure for the treatment of hematologic diseases, yet it is associated with high risks of treatment-related complications. Except for transplant-related organ toxicities, renal insufficiencies which emerge earlier significantly limit patients' long survival. To analyze risk factors for acute kidney injury (AKI), we conducted a retrospective cohort study of 96 patients undergoing HSCT.
METHODSDuring the first 100 days after allo-HSCT, all patients were evaluated for renal function by measuring serum creatinine clearance and glomerular filtration rate (GFR) with a classification below: Grade 0 (<25%, decline in creatinine clearance), Grade 1 (≥25% decline in creatinine clearance but <2-fold increase in serum creatinine), Grade 2 (≥2-fold rise in serum creatinine but no need for dialysis), and Grade 3 (≥2-fold rise in serum creatinine and need for dialysis). Cox regression model was used to calculate the hazard ratios (HRs) of demographic data, clinical variables, and risk factors for AKI.
RESULTSTwenty-eight (29.2%) patients occurred Grades 1-3 renal dysfunction (Grade 1, 14 patients; Grade 2, 12 patients; Grade 3, 2 patients), and ratios of early kidney injury increased in high-risk malignancy group (HR = 2.945, 95% confidence interval (CI)=1.293-6.421), patients treated with myeloablative conditioning regimen (HR=2.463, 95% CI=1.757-4.320), and patients with acute GVHD (HR=3.553, 95% CI=1.809-6.978), sepsis (HR=3.215, 95% CI=1.189-6.333 ), or hepatic veno-occlusive disease (VOD) (HR=3.487, 95% CI=1.392-6.524). Whereas, HLA histocompatibility showed no striking increased risk for acute renal injury (HR=1.684, 95% CI=0.648-4.378). The survival rate was lower in patients with severe nephrotoxicity (21.4%) than in patients without nephrotoxicity (70.6%) (P=0.001).
CONCLUSIONSNephrotoxicity is the primary risk factor for AKI, severely impacting on survival. Sorts of risk factors mentioned will be useful for evaluation for kidney function of patients undergoing allo-HSCT.

The aim of this study was to analyze the risk factors for overall survival at 5 years in 96 patients undergoing allogeneic hematopoietic stem cell transplantation by retrospective analysis. 11 clinical parameters including age, sex, disease status, HLA locus, donor type, donor-recipient blood type, conditioning regimen, aGVHD, HC, VOD and IP were selected for univariate analysis by using a Cox regression. Factors have statistic significance at the 0.1 level on univariate analysis were evaluated by multivariate analysis by a Coxs regression. The cumulative incidence of aGVHD and survival rate of patients were calculated by the method of Kaplan and Meier. The results showed that 95 patients achieved sustained donor engraftment except 1 patients. The median time of leukocyte engraftment (ANC > or = 0.5 x 10(9)/L) was 13 days. The aGVHD of I - IV grade was observed in 42 out of 96 patients (43.75%), in which 11 patients were with aGVHD of I grade (11.46%), 19 patients were with aGVHD of II grade (19.79%), 12 patients were with aGVHD of III - IV grade (12.50%). Out of 96 patients 10 relapsed and 38 dead, the overall survival at 5 years was 60.42%. The Cox regression analysis showed that aGVHD and disease status before transplant were main factors affecting long-term survival of patients, relative risks of which were 2.996 and 2.619 respectively. It is concluded that the main factors affecting long-term survival of patients are aGVHD and disease status. The key to improve the outcome of allo-HSCT is to reduce the incidence and severity of aGVHD, meanwhile to select the CR1 for allo-HSCT to treat the patients in advanced refractory and relapsed situation should be considered as important risk factors.

This paper aims to summarize the achievements during the implementation process of good agricultural practice (GAP) in Chinese Materia Medica (CMM), and on basis of analyzing the existing problems of GAP, to propose further implementation of GAP in TCM growing. Since the launch of GAP in CMM growing ten years ago, it has acquired great achievements, including: (1) The promulgation of a series of measures for the administration of the GAP approval in the CMM growing; (2) The expanded planting area of CMM; (3) The increased awareness of standardized CMM growing among farmers and enterprises; (4) The establishment of GAP implementation bases for CMM growing; (5) The improvement of theory and methodology for CMM growing; (6) The development of a large group of experts and scholars in GAP approval for CMM production. The problems existing in the production include: (1) A deep understanding of GAP and its certification is still needed; (2) The distribution of the certification base is not reasonable; (3) The geo-economics effect and the backward farming practices are thought to be the bottlenecks in the standardization of CMM growing and the scale production of CMM; (4) Low comparative effectiveness limits the development of the GAP; (5) The base of breeding improved variety is blank; (6) The immature of the cultivation technique lead to the risk of production process; (7) The degradation of soil microbial and the continuous cropping obstacle restrict the sustainable development of the GAP base. To further promote the health and orderly GAP in the CMM growing, the authors propose: (1) To change the mode of production; (2) To establish a sound standard system so as to ensure quality products for fair prices; (3) To fully consider the geo-economic culture and vigorously promote the definite cultivating of traditional Chinese medicinal materials; (4) To strengthen the transformation and generalization of basic researches and achievements, in order to provide technical support for the CMM production; (5) To deepen the understanding of GAP, to vigorously promote ecological planting and precision agriculture, in order to overcome the continuous cropping obstacle. The authors think that despite the fact that we are still facing with a huge array of management and technological problems, the GAP in the CMM growing has already enjoyed widespread support and showed great potential. In the future, with people's deeper understanding of GAP and the great progress of the science and technology, the GAP will constantly be fused with the theory, methodology and technology in the modern agriculture like precision agriculture, eco-agriculture and etc.
