OBJECTIVETo explore the incidence, degree, and pattern of rib cartilage calcification in congenital microtia patients, in order to provide reference for harvesting the rib cartilage, sculpturing cartilage framework.
METHODSFrom Jun. 2013 to Nov. 2014, 383 patients (age range, 6-45 years) underwent CT scans of the chest. 11 patients with bony diseases or traumatic history were excluded. The remaining 372 patients were divided by age into four groups as 6-15, 16-25, 26-35, 36-45 years old. Twenty patients (10 male and 10 female) were selected by the order of patient identification number in each age group, thus selecting a total of 80 patients (40 male and 40 female). Retrospective study of CT scans of the chest in 80 patients and the incidence, degree, and pattern of cartilage calcification of the sixth to eighth ribs were noted. A chi-square test is conducted to test whether there are significant difference between the variables through the SPSS 19.0 software.
RESULTSOverall, 40.4% (194/480) cartilage was calcified; female patients (47.50%, 114/240) showed higher frequency of calcification than male patients (33.33%, 80/240, P = 0. 025). Calcification rates of all age groups are 1.7% (2/120), 46.7% (56/ 120), 49.2% (59/120), 64.2% (77/120). Calcification rate of 6-15 years group is lowest in all groups (P < 0.05) while other three groups have no statistical significance (P > 0.05). Calcification rates of the sixth and sevent rib cartilage were higher than those of the eighth rib cartilage in all age groups except 6-15 years group, who had a similar rate of all three ribs. Calcification rate of all three rib cartilage was significantly increased with age. Calcification rates of the amle's rib cartilage and the female's in all age groups are 3.3% (2/60) and 0.0% (0/60) (6-15 years): 33.3% (20/60) and 60.0% (36/60) (16-25 years): 40.0% (24/60) and 58.3% (35/60) (26-35 years), 56.7% (34/60) and 71.2% (43/60) (36-45 years). In 6-15 years group calcification rates of male and female had a similar rate, while female's rates were higher than male's rates in other three groups. Male and females mainly had the granular type of calcification [70.0% (56/80), 63.2% (72/114)].
CONCLUSIONSFemales who are over 16 years old should pay more attention to the possibility of middle-severe calcification before harvesting rib cartilage. These patients should take CT examination if necessary. In addition, the patients who had previous operation, or traumatic history, rib deformity, or spine deformity should select the CT examination.

The challenge of the emergence of drug-resistant influenza strains, which is caused by wide spread utilization of direct-acting antivirals (DAAs), accelerates the research and exploration towards host targeted agents. In contrast to DAAs targeting viral replication components, host targeted agents, which regulate host factors and pathways linked to viral replication, can interfere the replication of influenza. Additionally, the innate immune system is activated by influenza during the early stage of infection, so manipulating the innate immune response may prevent the viral infection. However, the excessive inflammatory response induced at the late phase of influenza infection would lead to severe tissue injures. Thus, it is very important to explore drugs with anti-inflammatory actions to suppress these immune imbalances and tissue injures. Here we overview the current progresses about host targets related to anti-influenza drugs.

Objective:To evaluate the role of esophagogastric junction contractile index (EGJ-CI) in distinguishing patients with refractory gastroesophageal reflux disease (RGERD) from functional heartburn (FH).Methods:From March 2014 to January 2018, 82 patients with proton pump inhibitor (PPI) refractory heartburn and/or regurgitation, who visited the Outpatient Department of Gastroenterology at The First Affiliated Hospital with Nanjing Medical University were enrolled, among them 50 patients with RGERD (RGERD group) and 32 patients with FH (FH group). EGJ-CI of RGERD group and FH group were compared. The sensitivity and specificity of EGJ-CI to distinguish RGERD from FH patients. The correlation between EGJ-CI and high resolution esophageal manometry parameters, baseline impedance level and 24 h impedance-pH monitoring parameters were analyzed. Mann-Whitney U test, receiver operator characteristic curve analysis and Spearman correlation analysis were used for statistical analysis. Results:The EGJ-CI of RGERD group was lower than that of FH group (25.8 mmHg·cm (14.1 mmHg·cm, 35.9 mmHg·cm)(1 mmHg=0.133 kPa) vs. 39.2 mmHg·cm (23.0 mmHg·cm, 60.8 mmHg·cm)), and the difference was statistically significant ( Z=-2.833, P=0.005). When the cut-off value of EGJ-CI was 35.8 mmHg·cm, the sensitivity and specificity to distinguish RGERD from FH were 76.0% and 62.5%, respectively; area under the curve was 0.69 (95% CI 0.57 to 0.81). EGJ-CI was positively correlated with lower sphincter resting pressure, integrated relaxation pressure, distal contractile integral, distal esophageal pressure, and mean nocturnal baseline impedance ( r=0.812, 0.631, 0.451, 0.490 and 0.401, all P<0.01). EGJ-CI was negatively correlated with DeMeester score, acid exposure time, total reflux episodes, acid reflux episodes, long reflux episodes and longest reflux time ( r=-0.363, -0.372, -0.346, -0.318, -0.300 and -0.291, all P<0.01). Conclusions:EGJ-CI can help to distinguish patients with FH from RGERD.

Objective To value the significance of TGFBR2 gene in mediating HepG2 cell proliferation by RNA interference technology. Methods Three kinds of siRNAs targeting TGFBR2 gene were designed, synthesized and transfected into HepG2 cells via lipofetamine2000. Among three kinds of siRNAs, only the one with the most interference efficacy was selected and the correspondent DNA sequence was inserted into plasmid pEGFP-N3. Then the recombinant plasmid of siRNA-pEGFP-N3 was transfected into HepG2 cell and western blot was used to detect the protein level of TGFBR2. Then, TGF-β1 was used to stimulate HepG2 cells with or without siRNA interference and proliferation of HepG2 cells was observed. Results Among these three siRNAs, siRN-1 appeared to be the most effective. After stimulated by 5ng/mL TGF-β1, proliferation of HepG2 cells showed a marked increase in siRNA-1 group compared with blank and siRNA-NC groups (P<0.05). For all that, the proliferation rate was still lower than that in normal HepG2 cell group without TGF-β1 stimulation. Conclusion By silencing TGFBR2 gene, inhibition of TGF-β1 signaling pathway to HepG2 cells could be decreased, thereby enhancing the cell proliferation.

PurposeTo evaluate the existence and extent of magnetic resonance(MR) artifacts caused by frequently used metallic dental materials and to compare the influence of different MRI sequences on artifacts.MethodsA total of 22 kinds and 25 metallic dental samples were tested with 1.5 T MR imager and gradient-echo sequence. Spin-echo and fast spin-echo were added to parts of these samples. Results Of all the 25 metallic dental samples, 11 including gold, amalgam, and silver point did not produce artifact. Titanium alloy and porcelain product fused in metal had mild artifacts. Whereas the remaining 12 samples such as the retention pin and pivot pin showed severe artifacts. Artifacts produced by retention pin, nickel chromium crown and so on were less severe on fast spin-echo. ConclusionsAttention should be paid to some of the metallic dental materials, which could cause severe MR artifacts and image degradation, when undergoing face,jaw and head MR examination. Artifacts can be alleviated by using proper metallic materials or choosing proper imaging sequence and parameters.
