This study was aimed to investigate the induction effect ofRe-Du-Ning (RDN) Injection on rat liver microsome CYP450 enzymes. SD rats were randomly divided into the solvent control group, positive control group as well as the low, middle and high dose group of RDN (1, 2, 4 mL·kg-1·d-1). After drugs were administrated continuously for 7 days, the rats were sacrificed. The liver was weighed and prepared to microsomes. Meanwhile, the liver coefficients of rats were calculated. And the protein content was detected by BCA method. Finally, activities of five important subtypes of CYP450 enzymes such as CYP1A2, CYP2C9, CYP2C19, CYP2D6 and CYP3A1/2 were measured by the“cocktail” method. The results showed that the levels of liver coefficients, microsome yield rate and activities of CYP450 subtypes increased significantly in the positive control group compared with the solvent control group (P < 0.01). There was no significant difference on the levels of liver coefficients, microsome yield and protein content between the low and middle dose group of RDN. However, there was significant difference on the levels of liver coefficients and microsome yield in the high dose group (P < 0.05). In terms of the influence on enzyme activity, RDN Injection can significantly induce the activities of CYP1A2 with dose dependence. It can induce the activities of CYP2C9 and CYP2C19 at the middle and high dose. However, there was no obvious influence on the activities of CYP3A1/2 and CYP2D6. It was concluded that the positive control group can obviously induce activities of CYP450, which can be used in the evaluation of induction experiments. RDN Injection had induction effect on CYP1A2, CYP2C9 and CYP2C19. But it had no influence on the activities of CYP3A1/2 and CYP2D6.

OBJECTIVESTo investigate a survey about acceptance of central slaughtering of live poultry in residents of Guangzhou.

METHODSWe conducted a telephone survey by sampling residents with fixed-line telephone and with normal hearing, whose age is more than 15 years, by Mitofsky-Waksberg two-stage method during Jan 6(th) to 8(th), 2014. 358 residents finished the telephone questionnaire by 12 320 health hot line. We investigated the acceptance rate of city-wide central slaughtering permanently. We compared the difference between the respondents and the 2010 Guangzhou census data by Cohen's effect sizes (w) and weighted by population age and sex. We used χ(2) test to compare the acceptance rate of central slaughtering in residents with different characteristic. We used multiple logistic regression analysis to analyze the factors.

RESULTSThe difference in gender and age was small between respondents and the 2010 Guangzhou census data (w value was 0.13, 0.28, respectively), but that in education and marital status was large (w value was 0.52, 0.31, respectively). 49.0% (95% CI: 43.7%-54.3%) accept city-wide central slaughtering permanently. The acceptance rate of city-wide central slaughtering permanently in those who bought fresh, chilled and frozen poultry in their family in previous year was 54.3% (133/245), 60.0% (57/95) and 59.8% (49/82), respectively. It was more than those who didn't buy fresh, chilled and frozen poultry (38.1% (43/113), 44.9% (118/263) and 45.7% (126/276); χ(2) values were 8.15, 6.40 and 5.03; P values were 0.004, 0.011 and 0.025, respectively). The acceptance rate of city-wide central slaughtering permanently in those who deem fresh poultry taste better than live poultry was 64.9% (24/38). It more than those who deem not (47.0%, 151/320) (χ(2) = 4.22, 6.02, P = 0.040, 0.014, respectively). The acceptance rate of city-wide central slaughtering permanently in the male (OR = 2.68, 95% CI: 1.64-4.37) and those who deem getting sick due to buying live birds from LPM (OR = 1.72, 95% CI: 1.05-2.82), who can accept only fresh poultry carcass supply (OR = 2.39, 95% CI: 1.33-4.30), Who bought live poultry in their family in previous year (OR = 0.29, 95% CI: 0.11-0.74), who will decrease the consumption after ban on live poultry sale (OR = 0.50, 95% CI: 0.30-0.83) was 58.6% (109/186), 59.0% (92/156), 60.7% (139/230), 44.9% (132/295), 36.6% (68/186), respectively.

CONCLUSIONIn the early stage of avian influenza A(H7N9) epidemic in Guangzhou, the rate of acceptance of central slaughtering permanently in residents was not so high. Who deem getting sick due to buying live birds from LPM, who could accept only fresh poultry carcass supply and the male more accept city-wide central slaughtering permanently.

Objective:To compare the short-term clinical effect between laparoscopic distal pancreatectomy (LDP) and open distal pancreatectomy (ODP).Methods:We performed a retrospective study on 161 patients who underwent pancreatectomy between September 2017 to December 2018 in the Department of Pancreatic and Gastric Surgery, Cancer Hospital of Chinese Academy of Medical Sciences. According to the mode of operation, the patients were divided into the LDP group ( n=43) and the ODP group ( n=118). To compare the short-term clinical effect and safety between the LDP group and the ODP group, the preoperative clinical data, intraoperative related index, postoperative complication, postoperative recovery index, preoperative and postoperative inflammatory index were analyzed. Results:The preoperative clinical characteristics between the LDP group and the ODP group were not statistically different ( P>0.05). The intraoperative blood loss in LDP group was (194.19±241.83) ml, significantly less than (315.17±295.94) ml in ODP group ( P<0.05), and the postoperative exhaust time in LDP group was (3.00±0.72) days, significantly shorter than (4.05±0.97) days in OPD group ( P<0.001). The time to get out of bed in LDP group was (3.14±1.01) days, significantly shorter than (3.55±1.05) days in OPD group ( P<0.05). The postoperative eating time in LDP group was (3.88±1.61) days, significantly shorter than (5.11±1.56) days in ODP group ( P<0.001). The time of the drainage tube removal in LDP group was (8.44±1.93) days, significantly shorter than (9.82±3.70) days in ODP group ( P<0.05). The postoperative hospital stay in LDP group was (9.65±3.57) days, significantly shorter than (11.99±6.57) days in ODP group ( P<0.05). The mean operation time in LDP group was (168.65±55.45) min, shorter than (171.23±65.61) min in ODP group, but without significant difference ( P>0.05). The incidences of non-pancreatic fistula-related complications in LDP group and ODP group were 16.3% and 11.0%, respectively, without statistical significance ( P>0.05). The incidences of pancreatic fistula in LDP group and ODP group were 16.3% and 19.5%, respectively, without statistical significance ( P>0.05). The total incidences of complications in LDP group and ODP group were 32.6% and 30.5%, respectively, without statistical significance ( P>0.05). The preoperative and postoperative inflammatory indexes between these two groups were not statistically different ( P>0.05). Conclusions:Compared with ODP, LDP has the advantages of less intraoperative blood loss, faster postoperative recovery, shorter postoperative hospital stays, without increased postoperative complications and prolonged operation time. LDP is a safe and feasible operation method, and its short-term clinical effect is better than that of ODP.

Objective To assess the safety, feasibility and short?term outcome of totally laparoscopic distal gastrectomy(TLDG). Methods Seventy?five patients who underwent laparoscopic distal gastrectomy in Cancer Hospital of Chinese Academy of Medical Science between August 2015 and April 2018 were enrolled in this study. A total of 46 laparoscopy?assisted distal gastrectomy ( LADG) cases and 29 TLDG cases were included. The Short?term outcomes and safeties of the two groups were compared. Results The operation time of TLDG group was significantly longer than that of LADG group (207±41 vs. 156± 34 min, P＜0.001), while the length of wound was shorter in the TLDG group (3.6±0.6 vs. 5.8±0.8 cm, P＜0.001). The time to first flatus in TLDG group was (3.3±0.6) days, significantly shorter than (3.7±0.8) days in LADG group ( P＝0.034). There were no significant differences between the two groups in the estimated blood loss, intraoperative blood transfusion, extraction of gastric tube, drainage tube removal, interval of the first time to eat semi?liquid food, postoperative hospital stays, surgical complications, number of retrieved lymph nodes, proximal and distal resection margin lengths ( all P＞0.05). The white blood cell count at postoperative day 1 in the TLDG group was (10.96±1.96)×109／L, significantly lower than (12.49± 3.46)×109／L of the LADG group ( P＝0.017).While the CRP level at postoperative day 1 in the TLDG group were lower than that of LADG group, no statistical difference was observed (P＝0.072). Conclusions Our study shows that TLDG is safe and feasible. TLDG has better cosmesis, less blood loss, and faster recovery compared to LADG.

Objective:To analyze the results of lymphocyte subsets and 12 plasma cytokines in patients with tuberculosis by flow cytometry and to evaluate their diagnostic efficacy in these patients.Methods:This is a retrospective case-control study. A total of 128 patients with evidence of tuberculosis disease or clinically confirmed tuberculosis who were admitted to the 8th Medical Center of PLA General Hospital from January 2022 to December 2023 were included. According to the location of mycobacterium tuberculosis infection, the patients were divided into the pulmonary tuberculosis group (83 cases) and the extrapulmonary tuberculosis group (45 cases), and 100 healthy age-and sex matched people who underwent health check up during the study period were selected as the control group. Flow cytometry was used to detect peripheral blood lymphocyte subsets and 12 plasma cytokines [including 10 pro-inflammatory factors: interleukin (IL)-5, interferon (IFN)-α, IL-2, IL-6, IL-1β, IFN-γ, IL-8, IL-17, IL-12P70, Tumor necrosis factor (TNF)-α, and two anti-inflammatory factors: IL-4, IL-10] in participants of all groups. Spearman correlation method was used to analyze the correlation between lymphocyte subsets and cytokines, binary Logistic regression was used to screen the TB related factors, and receiver operating curve (ROC) was used to evaluate the diagnostic efficacy of TB related factors.Results:Compared with the control group, the absolute number of CD3 +T lymphocytes, CD3 +CD8 +T lymphocytes, CD3 +CD4 +T lymphocytes, NK cells and B cells were lower in pulmonary tuberculosis group and extrapulmonary tuberculosis group (all P<0.05). Except for IL-1β, the levels of other 11 cytokines are all significantly higher in the pulmonary tuberculosis group (all P<0.01), and the levels of IL-6, IFN-γ, IL-17, TNF-α, IL-4 and IL-10 were significantly higher in extrapulmonary tuberculosis group (all P<0.05). Compared with extrapulmonary tuberculosis group, the level of IL-8 was higher in pulmonary tuberculosis group ( P=0.026). Spearman correlation analysis showed that IL-6, IFN-γ and IL-8 were negatively correlated with the absolute numbers of CD3 +T lymphocytes, CD3 +CD8 +T lymphocytes, CD3 +CD4 +T lymphocytes, NK cells and B cells (IL-6: R2=-0.30, -0.28, -0.32, -0.26, -0.28; IFN-γ: R2=-0.36, -0.31, -0.37, -0.25, -0.36; IL-8: R2=-0.14, -0.13, -0.16, -0.14, -0.22; all P<0.05), IL-10 was negatively correlated with the absolute number of CD3 +CD4 +T lymphocytes, NK cells and B cells ( R 2=-0.14, -0.19, -0.21, all P<0.05); Binary Logistic regression analysis showed that IL-6, IFN-γ, IL-8 and IL-10 were the related factors of tuberculosis ( OR=1.809, 1.136, 0.910, 2.218, all P<0.05), ROC curve analysis showed that the AUC of IL-6, IFN-γ, IL-8 and IL-10 in the joint diagnosis of tuberculosis was 0.845, the sensitivity was 0.766, and the specificity was 0.820. Conclusion:The lower absolute number of lymphocyte subsets and cytokine levels in patients with pulmonary tuberculosis and extrapulmonary tuberculosis indicate that their immune function is in a low state, and the higher levels of pro-inflammatory factors (IL-6, IFN-γ, IL-8) and anti-inflammatory factor (IL-10) indicates the higher inflammatory status, and evaluation of these 4 cytokines has satisfactory diagnostic efficacy for tuberculosis.
