3.Digital renovation of S2001 field X-ray vehicle
Chinese Medical Equipment Journal 1989;0(02):-
S2001 field X-ray vehicle is used to perform X-ray examination in the field hospital, while the disadvantages of the traditional film-screen radiography restrict its role of field examination in this digital era. By analyzing the detail of modern digital X-ray radiography, and comparing three different digital X-ray flat detectors, a solution is put forward to update S2001 field X-ray vehicle to a field digital X- ray radiography vehicle by using Canon CXDI digital X- ray detector.

International Journal of Surgery 2021;48(3):170-174,F3
Objective:To investigate the related factors of pancreatic fistula after laparoscopic-assisted distal gastrectomy (LADG).Methods:A retrospective analysis was performed of 189 patients who underwent LADG in Beijing Friendship Hospital, Capital Medical University from June 2017 to March 2018. Twenty-seven patients with postoperative pancreatic fistula and 27 randomly selected normal patients were included in the study. The preoperative characteristics and surgical data of all patients were recorded, including body mass index, visceral fat area, past history, preoperative tumor staging, operation time and bleeding volume, etc. The related factors of postoperative pancreatic fistula were analyzed. Measurement data were expressed as mean±standard deviation ( Mean± SD), and t-test was used for comparison between groups. Chi-square test was used to compare the count data between groups. Results:The patients with high body mass index ( t=3.956, P=0.003), high visceral fat area ( t=6.161, P=0.038), long operation time ( t=2.650, P=0.024), profuse hemorrhage ( t=1.887, P=0.042), complete lymphadenectomy ( t=2.092, P=0.001) were prone to postoperative pancreatic fistula, while there was no significant difference of visceral fat area/total abdominal fat area ( χ2=1.334, P=0.324), preoperative with pulmonary diseases ( χ2=0.750, P=0.379), coronary heart disease ( χ2=0.081, P=0.500), hypertension ( χ2=0.667, P=0.239), diabetes mellitus ( χ2=2.030, P=0.127), chronic kidney disease ( χ2=0.587, P=0.352), tumor stage( χ2=1.388, P=0.500) and other factors between the two groups. Conclusions:Obesity patients and LADG patients with long operation time are more likely to have postoperative pancreatic fistula. Comprehensive preoperative assessment and prudent intraoperative operation may be one of the effective methods to avoid postoperative pancreatic fistula.

Reversed phase high performance liquid chromatography with diode array detector was employed for simultaneous determination of five main index components and specific chromatograms analysis in Xiaochaihu granules with a linear gradient elution of acetonitrile-water (containing 0.1% phosphoric acid) as mobile phase. The results showed that five main index components (baicalin, baicalein, wogonoside, wogonin, enoxolone) were separated well under the analytical condition. The linear ranges of five components were 0.518 - 16.576, 0.069 - 2.197, 0.167 - 5.333, 0.009 - 0.297 and 0.006 - 0.270 mg x g(-1), respectively. The correlation coefficients were 0.999 9, and the average recoveries ranged from 95% to 105%. Twelve common peaks were selected as the specific chromatograms of Xiaochaihu granules with baicalin as the reference peak. There were good similarities between the reference and the ten batches of samples. The similarity coefficients were no less than 0.9. The analytical method established is highly sensitive with strong specificity and it can be used efficiently in the quality control of Xiaochaihu granules.

Objective To explore the effect of the recombinant plasmid pcDNA3.1/C-sis on fulminant hepatic failure (FHF) in rats.Methods 48 h after recombinant plasmid pcDNA3.1/C-sis being imported into rat liver by using the method of fluid mechanics,FHF in rats was induced by endotoxin (LPS)+D-galactosamine (D-GaIN).With fluorescence quantitative PCR and Western blotting,C-sis expression was tested.The apoptosis of rat liver was detected by using HE staining and measuring Caspase-3 activity.The expression changes of Bcl-2 and Bax were examined through using Western blotting.The mortality rate of rats was calculated during 24 h observation period.Resnlts Compared with the normal control group and FHF+ empty plasmid group,C-sis mRNA and protein expression levels were increased significantly in the FHF+C-sis plasmid group,there were statistically significant differences (P<0.01).Compared with the normal control group,the apoptotic hepatocytes were increased in the FHF + Ringer's solution injection group and FHF+ empty plasmid group;compared with FHF+ empty plasmid group,the apoptotic hepatocytes in the FHF+C-sis plasmid group were decreased.Compared with the normal control group,Caspase-3 expression level was increased in the FHF+ Ringer's solution injection group (P<0.01);compared with the FHF+ empty plasmid group,Caspase-3 expression level in the FHF+C-sis plasmid group was decreased (P<0.05).Compared with the normal control group,Bcl-2 expression level was decreased significantly (P<0.01),and Bax expression level was increased significantly (P<0.01) in the FHF+Ringer's solution injection group;compared with the FHF+ empty plasmid group,the Bcl-2 expression level was increased (P<0.05),and Bax expression was decreased (P<0.05)in the FHF+C-sis plasmid group.During the 24 h observation period,all rats in the normal control group were alive;the mortality rates of the FHF+ Ringer's solution injection group and FHF+ empty plasmid group were 70.0% and 80.0% respectively,while that of the FHF+C-sis plasmid group was only 20.0%.Conclusion C-sis gene could inhibit FHF in rats induced by LPS+D-GalN.

OBJECTIVE: To observe the effects of kidney-tonifying Chinese herbal medicine on the synthesis and secretion of gonadotropin releasing hormone (GnRH) and the related neurotransmitters and neuropeptides, and to explore the mechanism of the regulative effect of Chinese herbal medicine on the hypothalamic-pituitary gonadotrophic function. METHODS: Female Sprague-Dawley rats during the period of normal adolescent initiation (160-180 g, 1.5 months) were randomly divided into three groups. The control group was fed with normal saline and the two experimental groups were fed with Chinese herbal medicine for nourishing yin to reduce fire (Zi Yin Xie Huo, ZYXH) or nourishing kidney to replenish essence (Yi Shen Tian Jing, YSTJ) respectively. The dosage was 5 ml/d for 30 days by gastric gavage. Integrated optic densities of the GnRH and neuropeptide Y (NPY) in medial preoptic area (MPOA), arcuate nucleus (ARC) and median eminence (ME) of hypothalamus were determined by immunohistochemistry method and image processing. The content of GnRH in homogenate of hypothalamus preoptic area was determined by radioimmunoassay (RIA). The releasing amount of monoamine neurotransmitters from medial basal hypothalamus (MBH) was determined by brain slices incubation and high pressure liquid chromatography (HPLC). The releasing amount of GnRH and NPY from POA was determined by push-pull perfusion and RIA, and the releasing amount of monoamine neurotransmitters from this site was determined by HPLC. RESULTS: ZYXH could inhibit the synthesis and secretion of GnRH from periodic and tonic secretory centers of GnRH, while YSTJ could stimulate the synthesis and secretion of GnRH from the both secretory centers of GnRH. ZYXH could inhibit the activity of GnRH neurons via diminishing the releasing of norepinephrine (NE) from tonic secretory center of GnRH, increasing the releasing of dopamine (DA) in periodic secretory center of GnRH and increasing the synthesis and releasing of NPY from the both secretory centers of GnRH, it hence inhibited the hypothalamic-pituitary gonadotrophic function. YSTJ could stimulate the activity of GnRH neurons via diminishing the synthesis and releasing of NPY from tonic secretory center of GnRH, it hence promoted the hypothalamic-pituitary gonadotrophic function. CONCLUSION: Chinese herbal medicine for tonifying the kidney could modulate hypothalamic-pituitary gonadotrophic function via regulating the synthesis and secretion of GnRH and the related neurotransmitters (NE, DA) and neuropeptides (NPY).
