The amount of acupuncture treatment refers to the sum of acupuncture effects during the treatment. From the factors that constitutes the amount of acupuncture treatment, including the numbers of needling, the size of acupuncture instruments, the depth of acupuncture, the manipulation, the retained time of needle, etc., and combined with teaching and clinical experience, it is believed that the amount of acupuncture treatment is closely related with clinical efficacy, besides, moderate amount of acupuncture treatment is a key factor to improve acupuncture efficacy and guarantee the safety of acupuncture. The basic principles of regular treatment amount are arrival of qi and being moderate, indicating the retained time of needle, treatment frequency and course should be based on individual condition, time, location and disease.

Objective To investigate the effect of fluvastatin on activation of nuclear factor kappa B (NF-κB)induced by angiotensin Ⅱ (Ang Ⅱ ) in rat kidney tubular epithelial cells (NRK-52E). Methods NRK-52E cells were divided into (1)control group ; (2)Ang Ⅱ groups with different concentration and time; (3)Ang Ⅱ (10-6 mol/L)+SB203580 ( 10 μmol/L)group; (4) Ang Ⅱ (10-6mol/L) +different fluvastatin concentration (10-7, 10-6, 10-5 mol/L)groups;(5)Ang Ⅱ (10-6mol/L) +fluvastatin (10-5 mol/L) +mevalonate (10-4 mol/L)groap. Electrophoretic mobility shift assays (EMSA) was used to detect NF-κB activation. Phosphorylation of cellular p38 mitogen-activated protein kinase (p38MAPK) was determined by Western blot. Monocyte chemoattractant protein (MCP)-1 mRNA was determined by RT-PCR. Results Ang Ⅱ stimulated the DNA-binding activity of NF-κB,phosphorylation of p38MAPK and up-regulated the expression of MCP-1mRNA in cultured NRK-52E cells in a dose-dependent manner (P<0.01). Ang Ⅱ (10-6 mol/L) induced a rapid (5 minutes) elevation of the p38MAPK phosphorylation. NF-κB DNA binding activity was increased at as early as 30 minutes(P<0.01), peaked at 2 hours after AngⅡ treatment (P<0.01). This stimulatory effect of Ang Ⅱ on NF-κB was blocked by SB203580 (a specific inhibitor of p38MAPK) (P<0.01). Incubation of cells with fluvastatin significantly inhibited the Ang Ⅱ-induced NF-κB activation and expression of MCP-1 mRNA in dose-dependent manner (P< 0.05). Exogenous mevalonate (10-4 mol/L) prevented the effect of fluvastatin on NF-κB activation (P <0.05). Conclusions Fluvastatin reduces Ang Ⅱ-induced NF-κB activation via the p38MAPK pathway in NRK-52E cells. Such effect of flurastatin is partly through blocked by mevalonate.

Objective　To provide data support for the prevention and control of melioidosis by analyzing epidemiological characteristics of melioidosis bloodstream infection and antibiotic resistance of its pathogen in Hainan Province from 2012 to 2021. Methods Data was collected from Hainan Antimicrobial Resistance Surveillance System, and WHONET 5.6 software was used to merge and analyze data. Results The case numbers of melioidosis bloodstream infection showed an increasing trend year by year from 2012 to 2021. The ratio of male to female patients was 4.6∶1, with 347 cases (58.91%) of patients aged 40-<60, the age group with the highest incidence. The number of cases from July to November were 424 cases (72.0%). Haikou and Sanya reported the largest case number, with 261 and 116 cases respectively. But there were no case reported from central area including Chengmai, Tunchang, Qiongzhong and Baoting. Burkholderia pseudomallei strains were isolated from both blood and other specimens in 105 of the 589 patients, with respiratory tract and wood specimens being the sites with the highest number of strains isolated other than blood; the resistance rates of Burkholderia pseudomallei to five antibiotics showed no obvious trend of change, with the lowest resistance rate to imipenem among the five drugs at 0.6%, followed by ceftazidime at 2.2%. Conclusion During the typhoon season, elderly, middle-aged male in coastal areas should pay attention to avoid or reduce their contact with mud and water. For patients with melioidosis bloodstream infection, imipenem or ceftazidime should be selected as early as possible for initial treatment.

Objective To assess the diagnostic value of CT spectral imaging using quantitative iodine-based material decomposition images in the evaluation of pulmonary embolism. Methods Fifty-three patients underwent CT angiography with spectral imaging mode on a GE Discovery CT750HD scanner. Iodine distribution in the lung parenchyma using the iodine-based material decomposition images was quantitatively measured by post-processing. Monochromatic CT angiographic images were reconstructed from the same data sets and thee images were reviewed for the identification and localization of pulmonary embolism as well as the degree ( partial or complete) of the embolic occlusion. The number and location of perfusion defects were recorded. The iodine content of perfusion defects and normal lung parenchyma on the iodine maps were measured by one reader using an ROI analysis. Comparative analyses were obtained using the Chi-square test for categorical data. Two independent samples rank test and 2 related samples signed-rank test were used to compare iodine densities between different groups. Results CT angiography showed no pulmonary embolism in 33 patients, and iodine distribution was homogeneous. A total of 93 clots with lobar ( n = 26), segmental (n = 54) and sub-segmental (n=13) distribution were detected in 19 patients; Fifty-one clots were occlusive and 42 clots were non-occlusive. The iodine-based material decomposition images of all occlusive clots showed lobar, segmental or sub-segmental iodine distribution defects; whereas eleven of 42 non-occlusive clots had evidence of iodine distribution defects. There was significant difference ( x2 = 39. 94,P＜0. 01 ) in the perfusion defects between occlusive and non-occlusive clots. There was a significant difference in iodine content between normal lung parenchyma [ (1.92 ±0. 54) g/L] and perfusion defects [ (0. 30 ± 0. 20)g/L] (Z= -5.63, P ＜ 0. 01 ). There was a significant difference in the iodine content of peffusion defects before [ (0. 26 ± 0. 23 )g/L] and after anticoagulation [ (0. 94 ± 0. 50 )g/L ] ( Z = -3.93,P ＜ 0. 01 ). Conclusion With the ability of iodine mapping, CT spectral imaging is areliable method in the evaluation of pulmonary embolism both qualitatively and quantitatively, and may be a useful tool in providing information regarding the severity of PE and monitoring therapeutic efficacy.

Abstract: Objective - - To establish a pre column derivatization high performance liquid chromatography method for detecting Methods dimethyl sulfate (DMS) in workplace air. DMS in workplace air was collected with mercaptopyridine impregnated （ silicone tube. The derivative of DMS and mercaptopyridine was eluted by mobile phase phase A: water, phase B: acetonitrile, ∶ the volume ratio was 40 60) , and separated with a C18 column, then detected with diode array detector and quantitated by a Results - standard curve. The linear range of DMS was 0.17 40.00 mg/L, with the correlation coefficient of 0.999 95. The detection limit and the lower limit of quantitation were 0.05 and 0.17 mg/L respectively. The minimum detection concentration and minimum quantitation concentration were 0.02 and 0.04 mg/m³, respectively (air sample volume of 4.5 L, 1.0 mL sample - - - solution). The average desorption efficiency was 98.40% 102.00%. The within run and between run relative standard deviations - - were 0.61% 3.92% and 1.71% 6.00%, respectively. The samples could be stored at room temperature for at least 14 days. Conclusion This method can be used to detect DMS in workplace air.
