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.

OBJECTIVETo explore the clinical effect of the method by using an expanded post-auricular skin flap combined with autologous rib cartilage framework for correction of concha-type microtia.

METHODSThe operation were performed in three stages. The expander was implanted under post-auricular skin at the first stage and expanded skin flap was formed. At the second stage, the expander was taken out and the expanded skin flap was transferred with autologous rib cartilage framework and skin graft for correction of microtia. At the third stage, the reconstructed ear was revised and new concha was formed.

RESULTSFrom August 2008 to August 2011, 108 cases with 113 concha-type microtia were corrected by this method. All patients healed primarily and were followed up for 6 months to 3 years. The reconstructed ears had a good appearance and position, and were symmetric to ear on the healthy sides.

CONCLUSIONSUsing expanded post-auricular skin flap combined with autologous rib cartilage framework is a reliable method for concha-type microtia.

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.

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.

OBJECTIVETo analyze the imaging features of osteopoikilosis and its diagnosis knowledge.

METHODSThe imaging data of 9 patients with osteopoikilosis were analyzed retrospectively, including 6 familial cases and 3 sporadic cases. In 6 familial cases,there were 4 males and 2 females with an average age of 28 years old ranging from 10 to 63 years. Clinical manifestations of 1 familial case were left knee pain and limitation of activity for 3 years, and other 5 cases without clinical manifestation. In 3 sporadic cases, there were 2 males and 1 female with an average age of 33.7 years old ranging from 25 to 44 years. Three sporadic cases had obvious injury history with following up from 6 to 12 months. All imaging results of 9 cases were observed.

RESULTSThe imaging data of 6 familial osteopoikilosis showed the multiple round or oval nodes within bone with clear margins, uniform density, different size. The occurrence of the hyperostotic spots preferentially localized in the epiphyses and metaphyses of the long bones, and carpus and tarus. X-ray features of 3 sporadic osteopoikilosis were similar to that of 6 familial cases and for 6 to 12 months follow-up X-ray features were unchanged.

CONCLUSIONThe imaging features of osteopoikilosis are relatively specific such as the multiple mottling dense focal within bone with clear border and bilateral symmetry, and the focus located on cancellous bone and the diaphyses usually is unaffected. The imaging is a valuable examination for the accurate diagnosis of osteopoikilosis.
