Objective This study aimed to study the effect of intra-brachial nitroglycerin administration via the angiography catheter on radial artery spasm in transradial percutaneous coronary intervention. Methods From patients undergoing transradial percutaneous coronary intervention (TRI) and succeeding in coronary angiography (CAG), 810 patients who needed percutaneous coronary intervention (PCI) (including Percutaneous Transluminal Coronary Angioplasty and/or stent implantation) were erolled, including 413 patients in the study group and 397 patients in the control group. When coronary angiography completed, positioned the angiography catheter over brachial artery and patients in the group received an administration of 400μg nitroglycerin via the angiography catheter. The control group received an administration of 400μg nitroglycerin via the sheath. The incidence of RAS were recored and compared. Resultes Baseline characteristics were similar between two groups. In the study group, the incidence of RAS was signiifcatively lower (18 vs. 33, P=0.021). Conclusions Intra-brachial nitroglycerin administration via the angiography catheter can prevent RAS during the insertion of guiding catheter in TRI.

Objective To explore the accuracy and practicability of the three-dimensional ultrasound in real-time intellectual positioning navigation.Methods The phantom was applied in the real-time intellectual positioning guided biopsy of three dimensional ultrasound,free-hand ultrasound-guided biopsy and bracket-guided biopsy with different depths(5 cm,10 cm) and different sizes of the targets (6 mm and 15 mm).The time spent,the length of the sample and the success rate of biopsy were compared among three groups,and statistical analysis was done.Results ①The different sizes of targets with different depths were shown in three kinds of biopsy that the real-time intellectual positioning guided biopsy of three-dimensional ultrasound spent more time than bracket-guided biopsy,less than free hand ultrasound-guided biopsy.The difference was significant (P ＜0.05).The aquired red-dyed sample was longer in the real-time intellectual positioning guided biopsy of three-dimensional ultrasound compared to free-hand ultrasound-guide biopsy and bracket-guided biopsy,the difference was significant (P ＜0.001).②For real-time IP-guided biopsy of three-dimensional ultrasound with same depth,larger size of targets(15 mm) spent less time than smaller saize of targets (6 mm),the difference was significant (P ＜ 0.05).However,compared to smaller saize of targets(6 mm),success rate of biopsy in larger size of targets(15 mm) had no significant difference (P =0.238 at depth of 5 cm,P =0.479 at depth of 10 cm).③For real-time intellectual positioning guided biopsy of three-dimensional ultrasound with same size,time spent was less in the targets at the depth of 5 cm than in the targets at the depth of 10 cm,the difference was significant (P＜0.05).The aquired red-dyed sample was longer in the targets at the depth of 5 cm than in the targets at the depth of 10 cm,and success rate of biopsy in the targets at the depth of 5 cm was higher too (P ＜0.05).Conclusions The real-time intellectual positioning guided biopsy of three dimensional ultrasound spend less time with high accuracy and success rate of biopsy,especially for smaller and deeper targets,can be clinically applied with accuracy and practicability.

Objective:To discuss the effect of amlodipine combined with atorvastatin in the treatment of elderly patients with acute cerebral infarction hypertension. Methods:Totally 86 cases with acute cerebral infarction hypertension were randomly divided into the treatment group (43 cases) and the control group (43 cases).

Objective:To investigate the clinical significance of the expression of oxidized α1-antitrypsin (ox-AAT) and neutrophil elastase (NE) in the peripheral blood and fetal membrane tissues of pregnant women with premature rupture of membranes (PROM).Methods:The clinical data of 95 cases of PROM pregnant women admitted to Binhai County People′s Hospital from April 2019 to April 2020 were analyzed. According to combination of histological chorioamnionitis (HCA), they were divided into PROM combined with HCA group ( 31 patients) and PROM without HCA group (64 patients). Besides, 50 normal pregnant women were collected during the same period as a healthy control group. The expression levels of ox-AAT and NE in the peripheral blood and fetal membrane tissues of the three groups were compared and analyzed.Results:The levels of peripheral blood ox-AAT and NE in the PROM combined with HCA group were higher than those in PROM without HCA group and healthy control group: (2.34 ± 0.02) ng/L vs. (1.50 ± 0.12), (0.32 ± 0.04) ng/L; (0.48 ± 0.08) ng/L vs. (0.13 ± 0.06), (0.11 ± 0.05) ng/L;the level of peripheral blood ox-AAT in PROM without HCA group was higher than that in healthy control group: (1.50 ± 0.12) ng/L vs. (0.32 ± 0.04) ng/L, and the differences were statistically significant ( P<0.05). The levels of fetal membrane tissues ox-AAT and NE in the PROM combined with HCA group were higher than those in PROM without HCA group and healthy control group: (0.031 ± 0.005) ng/L vs. (0.015 ± 0.002), (0.009 ± 0.003) ng/L; (0.020 ± 0.002) ng/L vs. (0.003 ± 0.001), (0.002 ± 0.001) ng/L; the level of fetal membrane tissues ox-AAT in PROM without HCA group was higher than that in the healthy control group: (0.015 ± 0.002) ng/L vs. (0.009 ± 0.003) ng/L, and the differences were statistically significant ( P<0.05). There was a positive correlation between ox-AAT and NE in peripheral blood and fetal membrane tissues ( r = 0.879, 0.875, P<0.05). The incidence of placental abruption in the PROM combined with HCA group and PROM without HCA group was higher than that in the healthy control group: 32.26%(10/31), 20.31%(13/64) vs. 4.00%(2/50), the incidence of neonatal pneumonia in the PROM combined with HCA group was higher than that in the PROM without HCA group and healthy control group: 25.81%(8/31) vs. 9.38%(6/64), 2.00%(1/50), and the differences were statistically significant ( P<0.05). Conclusions:The level of ox-AAT is overexpressed in peripheral blood and fetal membrane tissues of pregnant women with PROM, the level of NE is overexpressed in peripheral blood and fetal membrane tissues of PROM combined with HCA, and the increase of ox-AAT and NE expression is closely related to adverse perinatal outcomes.

Objective: To clone human T cell receptor (TCR) ? chain gene and express its encoding protein by baculoviral expression system in insect cells. Methods: TCR ? chain cDNA was cloned from normal human peripheral blood mononuclear cells (PBMC) by RT-PCR and inserted into baculoviral transfer vector. This vector was co-transfected with baculovirus into insect sf 9 cells. The recombinant protein expressed was identified by SDS-PAGE and flow cytometry with mouse anti-human ? chain monoclonal antibody. Results: Human TCR ? chain cDNA cloned and inserted into baculoviral vector specifically expressed protein in the insect sf 9 cells, accounting for about 11% of the total protein yield in the supernatant of cell lysate. The molecular weight of the recombinant protein determined by SDS-PAGE was identical to what we anticipated. The insect cells transfected with recombinant baculovirus were demonstrated by intracellular labeling flow cytometry to express ? chain protein. Conclusion: Human T cell receptor ? chain gene was successfully cloned from human PBMC, and its encoding protein was highly expressed in insect cells. The TCR ? chain protein obtained by bioengineering technique is useful for in depth biological function study.

[Objective] To investigate the pathological features, secretion of interleukin-8 (IL - 8), tumor necrosis factor alpha (TNF-?) and secretory immunoglobulin A (sIgA) and helicobacter pylori (HP) infection in gastric mucosa (GM) of chronic superficial gastritis with spleen-stomach and damp-heat syndrome (SSDHS) and to explore their correlations. [Methods] Fifty-five cases of chronic superficial gastritis included 35 cases of SSDHS (Group A) and 20 cases of spleen-deficiency syndrome (Group B). Fifteen asymptomatic volunteers served as normal control group (Group C). Pathological changes, HP infection rate, levels of IL - 8, TNF -? and sIgA in GM were observed. [Results] HP infection rate was higher and inflammatory change was more obvious in Group A than those in Group B and Group C (P 0.05). [Conclusion] Gastric mucosa of chronic superficial gastritis with SSDHS presents inflammatory changes, which is related with the increase of IL - 8 and TNF -? secretion and the decrease of sIgA, and HP infection may be one of the factors inducing and enhancing the pathological changes.
