Zebrafish (Danio rerio) is a simple biological labora-tory animal, with similar biological structure and physiological functions to mammals. Almost transparent embryos, in vitro de-velopment of embryos and up to 87% of human genetic similari- ties enable a wide application of zebrafish in the field of pharma-ceutical research. In this paper, we have studied the application of zebrafish in drug metabolism, the research of Chinese medi-cine, the evaluation of drug toxicology and safety, the screening of drugs and the discovery of new drugs, the research of regener- ative drugs, so as to provide new ideas of zebrafish in the field of pharmacy.

Objective To explore the characteristics of human plague using a sero-epidemiologic method in the source of the three rivers area in Qinghai for possible plague control strategies. Methods Investigate human plague sero-epidemiologically in the source of 4 counties in the three rivers area in Qinghai. The human serum would be tested to confirm the sew-positive rate for plague F1 antibody using indirect hemagglutination assay(IHA). Results A total of 2508 local participants were tested in 4 counties, the overall plague sero-positive rate was 2.31%(58/2508). This represents a statistically significant difference with 4 counties(X2=19.30,P<0.01). The sew-positive rate for males and females were 2.54% (32/1261) and 2.09% (26/1247), respectively. There were no statistically significant differences between males and females(X2= 0.65,P 0.05). The sero-positive rate in herdsman, cadre, Tibetan, Hart nationalities were 3.54% (44/1243), 6.47% (11 / 170), 2.40% (56/2335) and 1.47% (2/136), respectively. The sero- positive rate increased with age. The highest titre for human plague serum antibody was 1 : 640. Conclusion There were occult infections of plague in the population on source of three rivers area in Qinghai. Sero-epidemiologic data revealed that the human plague sero-positive rate was closely correlated with the local animal plague.

PURPOSE: Sleeve gastrectomy (SG) is an emerging approach, but there have been a surge in popularity because of its perceived technical simplicity, feasibility, and good outcomes. We describe results of a single fully experienced gastric surgeon's short-term outcomes of laparoscopic sleeve gastrectomy (LSG) and robotic sleeve gastrectomy (RSG) for morbidly obese patients. MATERIALS AND METHODS: We retrospectively reviewed 20 patients underwent LSG and RSG from July 2010 to February 2014. RESULTS: The mean age was 36.3+/-10.1 years, the mean preoperative body mass index (BMI) was 37.3+/-5.4 kg/m2. Mean operative time was 124.4+/-36.2 min. The postoperative length of stay was 5.1+/-4.1 day. There was no open conversion and mortality, nor severe postoperative complication found in the LSG and RSG cases. The mean BMI decreased to 26.1+/-2.5 kg/m2 at 1 year and the mean percentage excess weight loss was 69.8+/-24.9% at 1 year. CONCLUSION: Effective weight loss without complication would be achieved by sleeve gastrectomy if the procedure is performed by experienced gastric surgeon. However, further well-designed comparative studies with larger sample size are warranted to prove this preliminary result.

OBJECTIVETo observe the effects of marine protein peptide (MPP) on immunomodulating in mice and its possible mechanism.

METHODSFemale ICR mice (6-8 weeks old) were administered the MPP for 4 weeks with the dose of 0.22 g/kgBW, 0.45 g/kgBW and 1.35 g/kgBW. Spleen and thymus were weighted and cell-mediated immune functions, humoral immune functions, phagocytic functions of mononuclear phagocyte, NK cell activity assays, the T cell subpopulation of the spleen tissue by the flow cytometer and the concentrations of cytokines in serum by cytometric bead array were examined.

RESULTSThe capacity of lymphocyte proliferation induced by Con A (0.33 +/- 0.21), DTH response (0.36 +/- 0.11) mm in MPP 0.22 g/kgBW group were significantly increased in comparison with these values in control group (0.15 +/- 0.10) and (0.21 +/- 0.10)mm, respectively, P < 0.05. IgM-PFC number of MPP 0.22 g/kgBW group (1.64 +/- 0.06), 0.45 g/kgBW group (1.59 +/- 0.05) and 1.35 g/kgBW group (1.56 +/- 0.10) were higher than those in control group (1.38 +/- 0.10), P < 0.01; and the level of serum HC50 of MPP 0.22 g/kgBW group (141.00 +/- 23.00) and 0.45 g/kgBW group (130.40 +/- 33.20) were greater than the control (100.30 +/- 19.40) , P < 0.01. The activity of NK cells in MPP 0.22 g/kgBW group (1.672 +/- 0.142) was significantly elevated in comparison with this value in control group (1.392 +/- 0.182), P < 0.05. The percentage of CD4 T helper (Th) cell in spleen of MPP 0.22 g/kgBW group (32.84 +/- 3.776)% and 0.45 g/kgBW group (32.42 +/- 3.507) % was higher than those in control group (25.06 +/- 0.354) %, P < 0.05. The concentrations of IL-2 in serum of MPP 0.22 g/kgBW group 181.06 pg/ml, 0.45 g/kgBW group 94.84 pg/ml and 1.35 g/kgBW group 102.61 pg/ml were higher than those in control group 0.50 pg/ml, P < 0.05; and the level of IL-5 of MPP 0.22 g/kgBW group (38.31) pg/ml was greater than the control 0.50 pg/ml, P < 0.05. Nevertheless, no obvious effects on weight increasing, the ratio of immune organ and body weight and phagocytosis capacity were observed in our study.

CONCLUSIONMPP could improve the immune functions in mice, and might be by the mechanism of enhancing the function of Th cells stimulating the secretion of Th1 and Th2 type cell cytokines.

BACKGROUNDPatients aged over 85 years have been under-represented in percutaneous coronary intervention (PCI) trials despite an increase in referrals for PCI. The long-term safety and efficacy of percutaneous coronary stenting in patients aged over 85 years with acute coronary syndrome (ACS) remain unclear. Moreover it is unknown whether there are differences between bare metal stent (BMS) and drug eluting stent (DES) in this special population.

METHODSA total of 80 patients with ACS aged over 85 years undergoing stenting (BMS group n = 21 vs DES group n = 59) were retrospectively studied. In-hospital, one year and overall clinical follow-up (12 - 36 months) of major adverse cardiac events (MACEs) including cardiac deaths, myocardial infarction, target lesion revascularization (TLR) and target vessel revascularization (TVR) as well as stroke and other major bleeding were compared between the two groups.

RESULTSIn the entire cohort, the procedure success rate was 93.8% with TIMI-3 coronary flow post-PCI in 93.8% of the vessels and the procedure related complication was 17.5%. The incidence of in-hospital MACEs in BMS group was higher (14.3% vs 6.8%, P = 0.30). The 1-year incidence of MACEs in DES group was 7.0% while there was no MACE in the BMS group. Clinical follow-up for 12 - 36 months showed that the overall survival free from MACE was 82.9% and the incidence of MACE in the BMS group was lower (5.3% vs 21.1%, P = 0.20). Multivariate regression analysis showed that the creatinine level (OR: 1.013; 95% CI: 1.006 - 1.020; P = 0.004) and hypertension (OR: 3.201; 95% CI: 1.000 - 10.663; P = 0.04) are two major factors affecting the long-term MACE.

CONCLUSIONSPercutaneous coronary stenting in patients aged over 85 years is safe and provides good short and long-term efficacy. Patients with renal dysfunction and hypertension may have a relatively high incidence of MACE.

OBJECTIVE: To review the clinical data of pathological morphology, diagnosis, surgical treatment of cor triatriatum in 15 patients. METHODS: Fifteen patients with a mean age of (14.6+/-10.3) years (range from 6 months to 40 years) were performed operations under extracorporeal circulation. Fourteen of the patients had cor triatriatum sinister, and 1 had cor triatriatum dexter; 12 of the 15 patients had other cardiac abnormalities. The excision of the fibromuscular membrane was accomplished through a right atrial incision in all of the 14 cases, and the associated abnormalities were corrected at the same time. RESULTS: One patient died after the operation, and the other survivors had good outcome. CONCLUSION Operation is necessary if the diagnosis is clear. The patients generally have good prognosis. Surgical results of cor triatriatum depend on the complexity of associated defects and the adequacy of the repair.

PURPOSE: Identification of the infrapyloric artery (IPA) type is a key component of pylorus-preserving gastrectomy. As the indocyanine green (ICG) fluorescence technique is known to help visualize blood vessels and flow during reconstruction, we speculated that this emerging technique would be helpful in identifying the IPA type. MATERIALS AND METHODS: From August 2015 to February 2016, 20 patients who underwent robotic or laparoscopic gastrectomy were prospectively enrolled. After intravenous injection of approximately 3 mL of ICG (2.5 mg/mL), a near-infrared fluorescence apparatus was applied. The identified shape of the IPA was confirmed by examining the actual anatomy following infrapyloric dissection. RESULTS: The mean interval time between ICG injection and visualization of the artery was 22.2 seconds (range, 14–30 seconds), and the mean duration of the arterial phase was 16.1 seconds (range, 9–30 seconds). The overall positive predictive value (PPV) of ICG fluorescence in identifying the IPA type was 80% (16/20). The IPA type was incorrectly predicted in four patients, all of whom were obese with a body mass index (BMI) of more than 25 kg/m². CONCLUSIONS: Our preliminary results indicate that intraoperative vascular imaging using the ICG fluorescence technique may be helpful for robotic or laparoscopic pylorus-preserving gastrectomy.

PURPOSE: It is hypothesized that robotic gastrectomy may surpass laparoscopic gastrectomy after the operators acquire long-term experience and skills in the manipulation of robotic arms. This study aimed to evaluate the long-term learning curve of robotic distal gastrectomy (RDG) for gastric cancer compared with laparoscopic distal gastrectomy (LDG). MATERIALS AND METHODS: From October 2008 to December 2015, patients who underwent LDG (n=809) were matched to patients who underwent RDG (n=232) at a 1:1 ratio, by using a propensity score matching method after stratification for the operative year. The surgical outcomes, such as trends of operative time, blood loss, and complication rate, were compared between the two groups. RESULTS: The RDG group showed a longer operative time (171.3 minutes vs. 147.6 minutes, P<0.001) but less estimated blood loss (77.6 ml vs. 116.6 ml, P<0.001). The complication rate and postoperative recovery did not differ between the two groups. The RDG group showed a longer operative time and similar estimated blood loss compared with the LDG group after 5 years of experience (operative time: 159.2 minutes vs. 136.0 minutes in 2015, P=0.003; estimated blood loss: 72.9 ml vs. 78.1 ml in 2015, P=0.793). CONCLUSIONS: In terms of short-term surgical outcomes, RDG may not surpass LDG after a long-term experience with the technique.
