Objective:To study serum procalcitonin (PCT), C-reactive protein (CRP) and platelet count (PLT) in evaluation of severity of acute cholangitis (AC).Methods:Ninety patients with AC who were treated at the General Surgery Department, Guangming Hospital, Liaocheng, Shandong Province from January 2016 to December 2018 entered into the observation group, while 60 patients with bile duct stones but without infection treated at the hospital during the study period entered into the control group. Using the " Guidelines for the Diagnosis and Treatment of Acute Biliary Tract Infections" , the study group of patient was further divided into the mild infection, moderate infection, and severe infection groups. The PCT, CRP and PLT levels of all the subjects were checked. Spearman correlation was used to analyze the relationship between PCT, CRP, PLT indexes with severity of infection. The receiver operating characteristic curve was used to analyze the sensitivity and specificity of PCT, CRP and PLT in the diagnosis of patients with different degrees of infection.Results:In the observation group, there were 46 males and 44 females with a Mean±SD age of (45.6±21.1) years. In the control group, there were 30 males and 30 females, with a Mean±SD age of (45.0±19.3) years. The levels of PLT in the observation group and the control group were (8.2±1.1) ng/ml and (0.4±0.1) ng/ml, respectively. The corresponding CRP were (92.7±21.1) mg/L and (6.1±1.0) mg/L, respectively. The observation group had higher levels than the control group. The PLT counts were (62.6±17.6)×10 9/L and (156.3±35.3)×10 9/L for the two groups, with the observation group having lower platelet count than the control group (both P<0.05). The severity of infection was positively correlated with blood PCT levels and CRP indicators ( r=0.427, r=0.584, all P<0.05), and negatively correlated with the PLT ( r=-0.429, P<0.05). The sensitivity and specificity of PCT using a cut-off value of 9.4 μg/L were 84.0% and 65.0%, respectively, which were higher than the CRP using a cut-off value of 145.7 mg/L. The sensitivity and specificity were 67.0% and 48.0%, respectively. When PLT using a cut-off value of 52.8×10 9/L, the sensitivity and specificity were 71.0% and 52.0%, respectively. Conclusions:Changes in serum PCT, CRP and PLT reflected the severity of infection in patients with AC; PCT had a higher sensitivity and specificity, and it can be used to guide treatment.

The relationship of connexin43 (Cx43) and bystander effect in ovarian tumor cells in herpes simplex virus thymidine kinase/ganciclovir (HSV-TK/GCV) gene therapy in vitro was explored and the effect of all-trans retinoic acid (RA) on the expression of Cx43 and bystander effect investigated. The Cx43 expression was detected by flowcytometry, Western blot, and immunofluorescence in two ovarian tumor cell lines OVCAR3, CaOV3 before and after RA treatment. Bystander effect was determined by the cells growth inhibitory rate with methyl thiazolyl tetrazolium. Following exposure to ganciclovir, there was much greater bystander killing in OVCAR3 than that in CaOV3 (P<0.05). The expression of Cx43 was detected in OVCAR3 by flowcytometry and Western blot, but it could not be detected in CaOV3. The expression of Cx43 in both cell lines could be induced by RA. Immunofluoresence staining showed that Cx43 protein of OVCAR3 was located on membrane surface, whereas CaOV3 in cytoplasm. RA could not change the location of Cx43 protein in both cell lines. There is relationship between Cx43 expression and HSV-TK/GCV bystander effect. HSV-TK/GCV bystander effect can be enhanced by RA in ovarian cancer.

OBJECTIVETo evaluate the safety of a group A + C meningococcal polysaccharide vaccine as part of a phase IV clinical trial.

METHODSThe study area was divided into 108 clusters according to the principle of cluster randomization, stratified and paired sampling methods. 54 out of 108 clusters served as observation groups were administered A + C vaccine, while the rest 54 groups were administered Vi polysaccharide vaccine. An adverse event surveillance system was established to monitor the adverse events following the vaccination campaign. Identical form and methods were used for data collection to investigate the adverse events following the vaccination of both A+ C vaccine and Vi vaccine.

RESULTS34,543 people were vaccinated, including 18,167 of whom received A + C vaccine, while the other 16,376 received Vi vaccine. The rates of immediate injection reaction and unsolicited non-serious adverse events from A + C vaccine group were 0.44% and 0.38% while of Vi vaccine group were 0.79% and 0.73% respectively. At the solicited adverse event survey on 3-day-post-vaccination, 1239 vaccinees were followed-up including 771 received A + C vaccine and 468 received Vi vaccine. The local injection reaction rate of A + C vaccine group on the 1st day was significantly higher (X2 = 13.98, P = 0.0002) than that of Vi vaccine group. Neither the local injection reaction rate nor the system reaction rate between both groups was significantly different on 2nd and 3rd day, post vaccination. It was not statistically different when comparing fever onset rate between those who received vaccine and those who did not, in each vaccine group. There were no serious adverse events observed.

CONCLUSIONResults showed that the side effects of A + C vaccine and the Vi vaccine were mild and safe for vaccination campaigns targeting on populations at different age.

Background::The study aimed to describe the aortic valve morphology in Chinese patients underwent transcatheter aortic valve replacement (TAVR) for symptomatic severe aortic stenosis (AS), and the impact of sizing strategies and related procedural outcomes.Methods::Patients with severe AS who underwent TAVR were consecutively enrolled from 2012 to 2019. The anatomy and morphology of the aortic root were assessed. "Downsize" strategy was preformed when patients had complex morphology. The clinical outcomes of patients who performed downsize strategy were compared with those received annular sizing strategy. The primary outcome was device success rate, and secondary outcomes included Valve Academic Research Consortium-3 clinical outcomes variables based on 1-year follow-up.Results::A total of 293 patients were enrolled. Among them, 95 patients (32.4%) had bicuspid aortic valve. The calcium volume (Hounsfield Unit-850) of aortic root was 449.90 (243.15-782.15) mm 3. Calcium is distributed mostly on the leaflet level. Downsize strategy was performed in 204 patients (69.6%). Compared with the patients who performed annular sizing strategy, those received downsize strategy achieved a similar device success rate (82.0% [73] vs. 83.3% [170], P= 0.79). Aortic valve gradients (downsize strategy group vs. annular sizing group, 11.28 mmHg vs. 11.88 mmHg, P = 0.64) and percentages of patients with moderate or severe paravalvular regurgitation 2.0% (4/204) vs. 4.5% (4/89), P = 0.21) were similar in the two groups at 30 days after TAVR. These echocardiographic results were sustainable for one year. Conclusions::Chinese TAVR patients have more prevalent bicuspid morphology and large calcium volume of aortic root. Calcium is distributed mostly on the leaflet level. Compare with annular sizing strategy, downsize strategy provided a non-inferior device success rate and transcatheter heart valve hemodynamic performance in self-expanding TAVR procedure.
