Abstract
In order to understand the current status of main chemical components of atmospheric precipitation in Xi'an, the pH, electrical conductivity, mass concentration of water-soluble ions and heavy metals, wet deposition fluxes, and their sources in precipitation samples in urban and suburban areas of Xi'an in 2019 were studied. The results showed that the pH, conductivity, water-soluble ions, and heavy metals in precipitation in Xi'an in winter were higher than those in other seasons. The main water-soluble ions in precipitation were Ca2+, NH+4, SO2-4, and NO-3, and the sum of these ions accounted for (88.5%±2.8)% of the total ion concentration in urban and suburban areas. The main heavy metals were Zn, Fe, and Zn and Mn; their sum accounted for (54.0%±3)% and (47.0%±8)% of the total metal concentration. The wet deposition fluxes of water-soluble ions in precipitation in urban and suburban areas were (253.2±58.4) mg·(m2·month)-1 and (241.9±61.1) mg·(m2·month)-1, respectively. They showed higher values in winter than those in other seasons. The wet deposition fluxes of heavy metals were (86.2±37.5) mg·(m2·month)-1 and (88.1±37.4) mg·(m2·month)-1, respectively, with little seasonal difference. The source analysis using PMF showed that the water-soluble ions in urban and suburban precipitation mainly came from combustion sources (57.5% and 32.32%), followed by motor vehicles (24.4% and 17.2%) and dust sources (18.1% and 27.0%). The ions in suburban precipitation were also affected by local agriculture (11.1%). Heavy metals in precipitation in urban and suburban areas mainly came from industrial sources (51.8% and 46.7%), and the contribution rate of coal and motor vehicle mixed sources in winter was 10.7% and 6.1% higher than that in summer, respectively.

Abstract
In this study, we investigated the mechanism of crude extract of Psammosilene tunicoides(CEPT) in the treatment of rheumatoid arthritis(RA) based on the Nod-like receptor protein 3(NLRP3) inflammasome. The collagen-induced arthritis(CIA) mouse model was established. On day 32 after the primary immunization, according to the arthritis score, the mice were randomly divided into model group, positive control(methotrexate) group, low-and high-dose CEPT groups, and normal group, with 10 mice in each group. According to the administration dose of each group, the mice were continuously administered for 21 days. Every four days during the administration, the paw edema degree, arthritis score, and spleen index of the mice were measured; histopathological examination was performed for the ankles of the mice; the contents of IL-1β and IL-18 in the serum were determined; the protein expression levels of NLRP3, caspase-1, and apoptosis-associated speck-like protein containing a CARD(ASC), as well as the mRNA expression levels of NLRP3 and caspase-1 in the ankle joints of the mice were detected. The results showed that compared with those in the model group, the mice in the positive control group and CEPT groups had significantly decreased the contents of IL-1β and IL-18 in the serum and spleen index(P<0.01), significantly lowered arthritis score and degree of paw edema(P<0.01), alleviated arthritic infiltration of the knee, and down-regulated protein and mRNA levels of NLRP3, ASC, and caspase-1 in the ankle joint(P<0.01). These results suggest that P. tunicoides may reduce the paw edema and arthritis score and alleviate the inflammatory response in CIA mice by inhibiting the expression of NLRP3. This study provides a basis for the study of immune regulation of P. tunicoides in RA.

Methods: The clinical data of 300 patients with liver malignant tumor who received treatment from January 2016 to January 2017 in the Third Department of Hepatic Surgery of Eastern Hepatobiliary Surgery Hospital was retrospectively analyzed in this study, including 221 male and 79 female patients aged from 7 to 76 years with median age of 54 years. The median height was 168 cm (115-183 cm), the median weight was 65 kg (20-105 kg) and the median tumor volume was 142 ml (23-2 493 ml). Three-dimensional visualization technology was used in all patients to reconstruct liver three-dimensional graphics. Also, two and three-dimensional methods were taken respectively to evaluate patients and develop treatment strategy. The change of treatment strategy caused by 3D evaluation, actual surgical plan, operation time, time of hepatic vascular occlusion, intraoperative blood loss, volumes of blood transfusion and postoperative complications was observed. Results: After three-dimensional visualization technology was applied, 75(25%) of 300 patients' treatment strategies had been changed. The range of hepatectomy was extended in 25 patients. And 7 of them were due to hepatic venous variation, which resulted in increasing drainage area. In other 4 patients, liver resections were extended due to lack of perfusion of the liver parenchyma after the removal of portal vein. And hepatectomy was expanded in 14 patients in order to increase the surgical margin. The range of hepatectomy was reduced in 8 patients, 4 of which were due to hepatic venous variation, such as hepatic vein of segment 4 or lower right posterior hepatic vein. The remaining 4 cases were because of insufficient residual liver volume.The surgical resection was performed in 278 cases, 257 of which received operation directly. Left hepatectomy was performed in 24 patients and right hepatectomy was performed in 33 patients. Left trisectionectomy was carried out in 12 patients and right trisectionectomy was carried out in 11 patients. Caudate lobectomy was applied in 10 patients. There were 18 cases of left lateral sectionectomy, 7 cases of right anterior sectionectomy, 25 cases of right posterior sectionectomy and 18 cases of mesohepatectomy. Single or multi segment resection was performed in 99 patients. The treatment strategy of thirty-six patients was converted to staged hepatectomy (ALPPS 11 cases and portal vein embolization 25 cases). The median operation time was 130 minutes (90-360 minutes) and the median inflow blood occlusion time was 20 minutes (0-75 minutes). Median blood loss volume was 200 ml (20-1 600 ml). Thirty-seven of 278 patients received transfusions, and the average red blood transfusion volume was (4.4±1.7)units (0-8 units). Median hepatic resection volume was 530 ml(30-2 600 ml). There were 117 cases of pleural effusion after operation, including 3 patients needing invasive therapy. Ascites occurred in 23 patients, 6 of whom needed invasive therapy. Biliary leakage was observed in 30 patients. Eight patients occurred hepatic cutting surface hemorrhage, 6 of whom received blood transfusion, and 4 of whom underwent laparotomy to stop bleeding. Three patients had pulmonary infection after surgery and 3 patients appeared biliary obstruction. Deep vein thrombosis took place in 2 patients and portal vein thrombosis was observed in 4 patients. No postoperative liver failure and death ever happened in our study group. Conclusion: Three-dimensional visualization technique can optimize the treatment strategy of patients with liver malignant tumor, improve surgical safety.

Abstract
In this paper the metal-assisted electrochemical etching of silicon is introduced. By electrochemical measurement and sequent simulation, it is revealed that the potential of the valence band maximum at the silicon/metal interface is more negative than that of the silicon/electrolyte interface. Accordingly, holes injected from the back contact are driven preferentially to the silicon/metal interface. Consequently, silicon below metal is electrochemically etched much faster than a naked silicon surface without metal coverage. Metals such as Ag and Cu have been utilized to catalyze the electrochemical etching. Feature sizes as small as 30 nm can be achieved by metal-assisted electrochemical etching. Meanwhile, the metal-assisted electrochemical etching method enables convenient control over the etching direction of non-(100) substrates, and facilitates the fabrication of orientation-modulated silicon nanostructures.

Abstract
The aim of the present study was to examine the uterine expression pattern of implantation serine proteinase 2 (ISP2) protein during early pregnancy in mice and the effects of anti-ISP2 antibody on embryo implantation. Expression of ISP2 protein was found to be specifically up-regulated in mouse uterine endometrial glands following the initiation of embryo implantation. Similarly, ISP2 protein expression was observed during pseudopregnancy, indicating that its expression is not embryo dependent. In other experiments, rabbit anti-ISP2 IgG was infused into the mouse uterine lumen on Day 3 or 4 of pregnancy to examine its effects on embryo implantation, whereas vehicle (saline) or unspecific rabbit IgG served as controls. The mean number of implanted embryos from anti-ISP2-IgG-treated mice was significantly lower than that from control mice. These results suggest that ISP2 may play an important role during embryo implantation.

Abstract
AIMS To isolate and characterize the novel Bacillus thuringiensis strains from bryophytes collected from Wuyi Mountain, Fujian Province of China, and identify new B. thuringiensis strains and toxins active against mosquitoes. METHODS AND RESULTS Twelve novel B. thuringiensis strains were isolated from 76 bryophyte samples. According to the results of this preliminary screening, LLB6 was the most toxic to Aedes albopictus. Then phase-contrast as well as scanning electron microscopy, bioassays, cloning, sequencing and expression were performed to characterize the novel isolate LLB6 and its new gene cry2Ac5. CONCLUSIONS Bacillus thuringiensis occurred naturally on bryophytes. LLB6 isolated from Physcomitrium japonicum was toxic to A. albopictus. A new cry2Ac5 gene of LLB6 was detected, cloned and expressed successfully. Bioassays on A. albopictus showed that the expressed Cry2Ac5 was also toxic to the third instar larvae. SIGNIFICANCE AND IMPACT OF THE STUDY This is the first report of B. thuringiensis strains isolated from bryophytes. It represents a specific source of new B. thuringiensis strains and is of great importance for the knowledge of the ecology of B. thuringiensis. Novel LLB6 harboring the new gene cry2Ac5 and its expressed Cry2Ac5 protein revealed activity against A. albopictus and became a new member of B. thuringiensis toxins.

Abstract
HL-60 cells were treated by isoverbascoside with different time and different concentrations in vitro. The differentiation of HL-60 cells was evaluated by light and electron microscopy to observe morphological changes, by chemiluminence to detect phagocytosis and by tumorigenesis in nude mice to determine malignancy. The cytotoxical effect of isoverbascoside on HL-60 cells was examined by trypan blue excluding staining and electron microscopy. The influence of isoverbascoside on cell cycle was measured by flow cytometry. Granular differentiation of HL-60 cells was induced by isoverbascoside at 20-25 mumol/L within 1-3 days as the results of morphological changes, enhancement of phagocytosis and decreasing of tumorigenesis. Strong cytotoxicity was evidenced in HL-60 cells treated by isoverbascoside at 30-35 mumol/L. HL-60 cells treated by isoverbascoside at 20 mumol/L were delayed at G1 phase at 12 hours and G2/M phase at 72 hours.

Abstract
Free-standing aligned carbon nanotubes have previously been grown above 700 degreesC on mesoporous silica embedded with iron nanoparticles. Here, carbon nanotubes aligned over areas up to several square centimeters were grown on nickel-coated glass below 666 degreesC by plasma-enhanced hot filament chemical vapor deposition. Acetylene gas was used as the carbon source and ammonia gas was used as a catalyst and dilution gas. Nanotubes with controllable diameters from 20 to 400 nanometers and lengths from 0. 1 to 50 micrometers were obtained. Using this method, large panels of aligned carbon nanotubes can be made under conditions that are suitable for device fabrication.

Abstract
Analysis of liver specimens is an important issue in forensic toxicology, but suitable workup and extraction methods for general screening purposes have been lacking until now. A workup and extraction scheme based on a recently developed procedure for the screening of biological fluids was developed that can be used for the screening of acidic, neutral, and basic drugs in liver. This method uses a single solid-phase extraction (SPE) column and gas chromatography-flame ionization detection (GC-FID) for the final analysis. First, the homogenized liver sample is sonicated and centrifuged; the resulting supernatant is applied to the SPE column. Elution of acidic, neutral, and some weakly basic drugs is then performed with acetone-chloroform and analyzed by GC-FID. Next, the pellet of tissue material obtained from the centrifugation is enzymically digested by subtilisin Carlsberg. This frees the drugs bound to the liver tissue. The resulting clear liquid is brought to the reconditioned SPE column. A wash step is introduced to remove acidic and neutral interferences and the basic drugs can then be eluted with ammoniated ethyl acetate. Using 100-mg wet liver samples spiked with 2 micrograms of amounts of various drugs, recoveries were 70-102% with relative standard deviations less than 9%. The resulting GC-FID chromatograms were virtually free of endogenous interferences. GC-nitrogen-phosphorous detection detected smaller amounts of nitrogen-containing drugs, again without endogenous interferences. With the SPE columns currently used, which contain a bed mass of 130 mg, the liver samples should be smaller than 200 mg because the endogenous compounds obtained after the digestion of the tissue will overload the column, which results in a lower recovery of the drugs of interest. Drugs that decompose under the digestion conditions (pH 10.5 at 60 degrees C for 1 h) may be lost in the present procedure. This phenomenon is being investigated further.

Abstract
Acute and chronic effect of Radix Angelicae Sinensis (RAS) on serum gastrin levels in patients with cirrhosis were investigated. The results showed that after intravenous perfusion of RAS, serum gastrin levels of inferior vana cava, hepatic and peripheral veins were significantly decreased. After long-term administration of the agent, the level fell nearly to that of control subjects. It is suggested that the effect of reducing serum gastrin level by RAS may improve portal hemodynamics and be beneficial for portal hypertensive gastroduodenal mucosal lesions in cirrhosis.

Abstract
Collagen corneal shields immersed in 13.33 mg/ml gentamycin solution for 5 minutes were placed in rabbit eyes and the gentamycin concentrations in the cornea and aqueous humor were determined with radioimmunoassay. The results were compared with those achieved by soft contact lens, subconjunctival injection, and frequent instillations. It was found that (1) 1 and 3 hours after application, the collagen corneal shield produced significantly higher concentration of gentamycin in the aqueous than did the other methods, and in the cornea than did the contact lens or instillations; and (2) 6 hours after application, the antibiotic level in the cornea dropped lower than that by subconjunctival injection, but still 15-30 times higher than the bactericidal concentration.

Abstract
To explore a definite diagnostic criterion of chronic gastritis, we undertook a quantitative study of the gastric biopsy specimens taken from 131 subjects. Seven stages were classified from normal gastric mucosa to mild, moderate and severe superficial and atrophic gastritis. The results shown the number of inflammatory cell was much greater in the mild superficial gastritis (128 +/- 84.37/HP) than in normal gastric mucosa (22 +/- 10.54HP, P less than 0.001). In these stages, the numbers of pyloric and fundic gland progressively decreased, the size of the gastric gland gradually enlarged and the percentage of intestinal metaplasia by degrees increased. According to these, we establish the quantitative diagnostic criterion of chronic gastritis.

Abstract
A total number of 241 boys aged 13 to 16 were studied longitudinally for 8 months from April 1986 to December 1986. The linear correlation analysis showed that urinary HP/Cr was highly correlated with height growth rate (r = 0.83) and moderately with weight growth rate (r = 0.63). The multiple correlation coefficients between urinary HP/Cr and height growth rates were much bigger than those between urinary HP/Cr and weight growth rates, only the former were statistically significant. It is suggested that the urinary HP/Cr is mainly correlated with height growth rate. The multiple regression analysis was employed with urinary HP/Cr, age as independent variables and height growth rate as dependent variable. The equation is very significant, 95% confidence limit is y +/- 1.38%. It is suggested that the prediction of height growth rate is rather precise, so urinary HP/Cr is a valuable index in the evaluation of growth of children.

Abstract
The nuclear pore complex in spermatogenesis of Beijing domestic duck has been studied by means of electron microscopic observation of freeze-etching. The structure of the pore observed proves to be in accord with the model of the nuclear pore complex proposed respectively by Franke (1970) and Roberts et al. (1970). But its central granule may be present (1-3 granules) or absent. The granules are considered to be material in transit. The size and frequency of the pore vary with different types of reproductive cells, which is believed to be related to the cells' function. The pores concentrate on the side of nucleus near Golgi zone in primary spermatocyte and near the proacrosome of spermatid, and this shows the functional variety of parts in the nucleus.
