Objective To explore the effect and mechanism of stent implantation on the quality of sexual activity in middle and old age male patients with exertional angina pectoris.Methods One hundred and seventy-two male patients with exertional angina pectoris were enrolled in this study,and they were divided into control group (94 patients) and percutaneous coronary intervention group (78 patients).The patients in control group were given routine pharmacotherapy and the patients in percutaneous coronary intervention group were given drug-eluting stent implantation and routine pharmacotherapy.The sexual activity function was evaluated by international index of erectile function (IIEF)-5 scale before treatment and 3 months after treatment.The times of sexual intercourse was added up.The evaluation of angina pectoris was performed by the grade of Canadian cardiovascular society (CCS).At the same time,the walking distance and heart rate were measured through 6-minute walking test.The left ventricular ejection fraction(LVEF) was detected by echocardiogram.Results After treatment for 3 months,the scores of IIEF-5,the degree of sexual satisfaction,the times of sexual intercourse and the grade of CCS in percutaneous coronary intervention group were significantly improved compared with those in control group [(20.58 ± 7.36) scores vs.(16.38 ± 6.35) scores,(4.32 ± 1.38) scores vs.(2.51 ± 1.89) scores,(6.3 ± 3.2) times/month vs.(3.5 ± 1.6) times/month,(1.10 ± 0.43) grades vs.(2.50 ± 1.1 0) grades] (P ＜ 0.05).The walking distance and heart rate after 6-minute walking test and LVEF in percutaneous coronary intervention group were significant improved compared with those in control group [(386 ± 82) m vs.(281 ± 86) m,(95 ± 18) times/minute vs.(122 ± 25) times/minute,(65.2 ± 11.2)％ vs.(55.6 ± 13.8)％] (P ＜ 0.05).Conclusions Stent implantation can significandy improve the quality of sexual activity in middle and old age male patients with exertional angina pectoris.The mechanisms are associated with the exercise capacity increasing and the frequency of angina pectoris attacks decreasing during sexual intercourse.

Objective To investigate the influence of proton pump inhibitors (lansoprazole and rabeprazole) on dual-antiplatelet therapy (DAPT) in patients with coronary heart disease.Methods One hundred and eighty-one cases of coronary heart disease with DAPT were selected,and they were divided into control group (66 cases,no proton pump inhibitors administered),lansoprazole group (65 cases,lansoprazole administered) and rabeprazole group (50 cases,rabeprazole administered).100 mg/day of aspirin and 75 mg/day of clopidogrel were concomitantly used in all patients.Platelet aggregation rate,platelet aggregation threshold index (PATI) and adenosine diphosphate (ADP) was measured.Results The ADP-PATI in control group was (3.47 ± 0.96) μ mol/L,lansoprazole group was (3.28 ± 1.05) μ mol/L,rabeprazole group was (3.32 ±0.83) μ mol/L,and there was no statistically significant difference among three groups (P＞0.05).There was also no statistically significant difference in platelet aggregation rate and collagen-PATI among three groups (P ＞ 0.05).Conclusion In patients with coronary artery disease,the concomitant use of lansoprazole or rabeprazole does not affect antiplatelet action during DAPT.

Objective To investigate the influence of dexmedetomidine on expressions of protein kinase c (PKC)γ, cal?cium/calmodulin-dependent protein kinase (CaMK)Ⅱαand pCaMKⅡαin spinal cord in rats with incisional pain (IP) and remifentanil-induced hyperalgesia. Methods Forty male Sprague-Dawley rats, aged 2-3 months, weighing 240-260 g, were randomly divided into 5 groups (n=8 each):blank control group (group C), remifentanil+incisional pain group (group R+I), dexmedetomidine + remifentanil + incisional pain group (group D+R+I), dexmedetomidine + remifentanil + incisional pain+phorbol myristate acetate+DMSO group (group D+R+I+P+DMSO) and dexmedetomidine+remifentanil+incisional pain+DMSO group (group D+R+I+DMSO). The incisional pain rat model was established by a plantar incision in left hind paw. Remifentanil was infused at a rate of 1.2μg·kg-1·min-1 for 90 min via the caudal vein. Dexmedetomidine was adminis?tered subcutaneously at a dose of 50μg/kg at 30 min before plantar incision. Phorbol myristate acetate and DMSO were intra?thecally injected at a dose of 10 μL. Paw withdrawal latency (PWL) to thermal stimulation and paw withdrawal threshold (PWT) to von Frey hair stimulation were measured 24 h before remifentanil infusion (T0) and at 2, 6, 24 and 48 h (T1-4) after intraveonus remifentanil injection. The rats were sacrificed after the last behavioral test and the L 4-6 segment of spinal cord was removed to determine the expressions of PKCγ, CaMKⅡαand pCaMKⅡαin spinal cord by Western blot analysis. Re? sults Compared with group C, the value of PWL was significantly shortened and PWT was significantly decreased except T0, and the expressions of PKCγ, CaMKⅡαand pCaMKⅡαwere up-regulated in other groups. Compared with group R+I, the value of PWL was significantly prolonged and PWT was significantly increased, the expressions of PKCγ, CaMKⅡαand pCaMKⅡαwere down-regulated in group D+R+I and group D+R+I+DMSO. Compared with group D+R+I, the value of PWL was significantly shortened and PWT was significantly decreased, the expressions of PKCγ, CaMKⅡαand pCaMKⅡαwere up-regulated in group D+R+I+P+DMSO. Compared with group D+R+I+P+DMSO, the value of PWL was significantly prolonged and PWT was significantly increased, the expressions of PKCγ, CaMKⅡαand pCaMKⅡαwere down-regulated in group D+R+I+DMSO. Conclusion Dexmedetomidine can reduce the expressions of PKCγ, CaMKⅡαand pCaMKⅡαin spinal cord in rats with IP and hyperalgesia induced by remifentanil.

CC chemokine receptor 4 (CCR4) is a kind of G-protein-coupled receptor, which plays a pivotal role in allergic inflammation. The interaction between 2-(2-(4-chloro-phenyl)-5-{[(naphthalen-1-ylmethyl)-carbamoyl]-methyl}-4-oxo-thiazolidin-3-yl)-N-(3-morpholin-4-yl-propyl)-acetamide (S009) and the N-terminal extracellular tail (ML40) of CCR4 has been validated to be high affinity by capillary zone electrophoresis (CZE). The S009 is a known CCR4 antagonist. Now, a series of new thiourea derivatives have been synthesized. Compared with positive control S009, they were screened using ML40 as target by CZE to find some new drugs for allergic inflammation diseases. The synthesized compounds XJH-5, XJH-4, XJH-17 and XJH-1 displayed the interaction with ML40, but XJH-9, XJH-10, XJH-11, XJH-12, XJH-13, XJH-14, XJH-3, XJH-8, XJH-6, XJH-7, XJH-15, XJH-16 and XJH-2 did not bind to ML40.Both qualification and quantification characterizations of the binding were determined. The affinity of the four compounds was valued by the binding constant, which was similar with the results of chemotactic experiments. The established CEZ method is capable of sensitive and fast screening for a series of lactam analogs in the drug discovery for allergic inflammation diseases.

Recent years, China has released a series of policies to encourage drug research and development in pediatric populations, aiming to meet pediatric populations' medical needs. Because of the physical and psychological developmental characteristics, tolerance of aversive feelings when taking medications are different between pediatric population and adults. So pediatric populations are at a relatively higher risk of not taking medications as prescribed when the medication tasted unpleasant. Therefore, sound design and evaluation of oral sensory features have important clinical significance and value in developing pediatric medications. "Technical guidance for the design and evaluation of the oral sensory features of pediatric drugs (trial version) " was released in November 2022, by Centre for Drug Evaluation, National Medical Products Administration of China. Based on the guidance, this article will introduce the drafting background and review considerations, hoping to provide reference for the design and evaluation of oral sensory features, and promote drug developing in pediatric population.

OBJECTIVETo explore the effect of septoplasty or in combination with out fracture of the inferior turbinate in patients with nasal septum deviation on the airflow field and the nasal airway structure.

METHODSSix patients with nasal septum deviation underwent spiral CT imaging scans before surgery and during the follow-up. The 3D finite element meshes of the nasal airway were developed from the above CT scans. Given three preconditions, the nasal airflow fields were described by the Navier-Stokes and continuity equations at the inspiratory flow rate of 12 L/min. The whole airflow patterns were obtained and then compared with the airflow filed and airway structure changes before and after surgery. SPSS 12.0 software was used to analyze the data.

RESULTSBefore surgery, area of the common airway and the middle and ventral medial regions in the concave side were (1.61 ± 0.18), (0.40 ± 0.10), (0.40 ± 0.14) cm(2) respectively, and those of convex side were (1.30 ± 0.18), (0.33 ± 0.05), (0.36 ± 0.10) cm(2) respectively. The differences between both sides were of no statistical significance (Z value was 1.782, 1.363, 0.526 respectively, all P > 0.05). Airflow of the above airways were (361 ± 68), (131 ± 25), (100 ± 28) ml respectively in concave side and (178 ± 33), (59 ± 26), (59 ± 18) ml respectively in convex side, which differences were significant statistically (Z value were 2.207, 2.201, 2.201 respectively, all P < 0.05). The inferior turbinate in concave side [(0.93 ± 0.10) cm] was statistically (Z = 2.214, P < 0.05) bigger than that in convex side [(0.58 ± 0.12) cm] before surgery. The airflow fields were in disorder in both ill-airways. After surgery, area of the common airway was (2.55 ± 0.44) cm(2) in concave side and (2.20 ± 0.72) cm(2) in convex side respectively, and area of the middle and ventral medial regions in the convex side were (0.58 ± 0.13), (0.81 ± 0.26) cm(2) respectively, which differences were of significance statistically when comparing to areas before surgery (Z value were 2.201, 2.201, 2.201, 2.201, P < 0.05). The airflow passed through nasal airway orderly in both sides. But the thickness of inferior turbinate was (0.73 ± 0.08) cm in concave side after surgery, which difference was significant statistically in comparison to that before surgery (Z = 2.264, P < 0.05). Consequently, nasal resistance decreased from (0.41 ± 0.03) kPa×L(-1)×s(-1) to (0.16 ± 0.01) kPa×L(-1)×s(-1) after surgery, the difference was significantly (Z = -2.207, P = 0.027).

CONCLUSIONSeptoplasty or in combination with out fracture of the inferior turbinate, followed by the self-adaptation consecutively, could improve the airway and breathing capacity of the nose.

OBJECTIVETo evaluate efficacy of adjuvant chemotherapy after D2 dissection on survival for patients with gastric cancer.

METHODSRandomized clinical trials (RCT) that compared adjuvant chemotherapy after D2 dissection with D2 dissection alone for gastric cancer were searched with Pubmed, Cochrane, Embase and CBM databases. Eligible trials published between 1990 and 2012 were included in the study. The quality of RCTs was assessed by the Jadad scale. Data synthesis and statistical analysis were performed by RevMan 5.1 software.

RESULTEight RCTs with 3633 patients were included in this study. Among them, 1824 patients received adjuvant chemotherapy and 1809 patients didn't. Adjuvant chemotherapy was associated with a significant benefit in terms of overall survival (RR = 0.76, 95% CI: 0.69-0.84), disease free survival (RR = 0.72, 95%CI: 0.66-0.80) and recurrence rate (RR = 0.69, 95% CI: 0.62-0.77).

CONCLUSIONAdjuvant chemotherapy was associated with survival benefit for gastric cancer after D2 dissection.
