Interleukin ( IL) -38 is the most recently discovered cytokine, which is the tenth member of IL-1 cytokine family. IL-38 shares a high homology with IL-1 receptor antagonist ( IL-1 Ra) and IL-36 Ra. IL-36 R is the specific receptor of IL-38 which is the partial receptor antagonist of IL-36. Now, research has shown that IL-38 not only had relationship with intracellular infection and inflammation, but also with many clinical diseases such as autoimmune diseases, osteoarthritis, tumor and cardiopulmonary diseases. However, the molecular immune regulation mechanism of IL-38 is complicated, involving specific receptor recruitment, apoptosis mediated phagocyte regulation, regulation of Th17 cell differentiation and many other processes. It also provides several new clues to the treatment of diseases. IL-38 is a new cytokine research hot spot with extensive application prospects and need deep exploration.

Breast cancer is the most common cancer for Chinese women. Early screening is the best way to improve the rates of early diagnosis and early treatment of breast cancer. The peak ages of breast cancer in Chinese women are obviously different from those in the European and American countries. It is imperative to develop a guideline for breast cancer screening that is suitable for Chinese women. Based on the analysis and summary of breast cancer screening data in China, and the latest guidelines and consensus on breast cancer screening in Europe, the United States and East Asia, China Anti-Cancer Association and National Clinical Research Center for Cancer (Tianjin Medical University Cancer Institute and Hospital) has developed a population-based guideline for breast cancer screening in Chinese women. This guideline has provided detailed recommendations on the screening starting age, screening modalities, and screening interval in Chinese women with average risk and high risk of breast cancer, respectively. This article aims to interpret the above guideline, providing references for professionals in breast cancer screening.

OBJECTIVE:
To compared the therapeutic effect between filiform fire needle assisted 308 nm excimer laser and simple 308 nm excimer laser on vitiligo of different parts.
METHODS:
Target lesions of 134 patients were divided into an observation group and a control group according to the principle of self-controlled, 201 pieces in each one. In the observation group, filiform fire needle was performed at target lesions. Then target lesions both of the two groups were irradiated with 308 nm excimer laser at the same time. Once every 2 weeks, totally 10 treatments were required. The effective rate and effective rate, color recovery rate and responding time of different parts in the two groups were evaluated 2 weeks after treatment.
RESULTS:
The effective rate in the observation group was 82.59% (166/201), which was higher than 68.16% (137/201) in the control group (<0.01). The effective rate of face-neck, trunk, limbs and hand-foot were 90.32%, 81.63%, 81.48% and 58.62% respectively in the observation group, which were higher than 82.80%, 69.39%, 51.85% and 31.03% in the control group (<0.01, <0.05). The color recovery rate of different parts in the observation group was higher than the control group, and the effect was faster in the observation group (<0.01, <0.05).
CONCLUSION
Filiform fire needle as an adjunctive therapy, combined with 308 nm excimer laser are more effective than simple 308 nm excimer laser for vitiligo of different parts. Combination therapy has a shorter responding time, the face-neck has the best effect and hand-foot has poor effect.

Objective To evaluate the optic nerve impairment using MRI histogram texture analysis in the patients with optic neuritis.Methods The study included 60 patients with optic neuritis and 20 normal controls. The coronal T2 weighted imaging (T2WI) with fat saturation and enhanced T1 weighted imaging (T1WI) were performed to evaluate the optic nerve. MRI histogram texture features of the involved optic nerve were measured on the corresponding coronal T2WI images. The normal optic nerve (NON) was measured in the posterior 1/3 parts of the optic nerve. Kruskal-Wallis one-way ANOVA was used to compare the difference of texture features and receiver operating characteristic (ROC) curve were performed to evaluate the diagnostic value of texture features for the optic nerve impairment among the affected optic nerve with enhancement (ONwEN), affected optic nerve without enhancement (ONwoEN), contralateral normal appearing optic nerve (NAON) and NON.Results The histogram texture Energy and Entropy presented significant differences for ONwEN vs. ONwoEN (both P=0.000), ONwEN vs. NON (both P=0.000) and NAON vs. NON (both P<0.05). ROC analysis demonstrated that the area under the curve (AUC) of histogram texture Energy were 0.758, 0.795 and 0.701 for ONwEN vs. ONwoEN, ONwEN vs. NON and NAON vs. NON, AUC of Entropy were 0.758, 0.795 and 0.707 for ONwEN vs. ONwoEN, ONwEN vs. NON and NAON vs. NON.Conclusions The altered MRI histogram texture Energy and Entropy could be considered as a surrogate for MRI enhancement to evaluate the involved optic nerve and normal-appearing optic nerve in optic neuritis.

The patient was a female infant aged 1 month and 29 days. She was admitted to the hospital due to convulsions for 6 days and increased blood glucose level for 5 days. She had unstable blood glucose levels. The level of glycosylated hemoglobin was too high to measure. Urine glucose was positive (+ - ++++). The levels of fasting C-peptide and insulin were 0.19 ng/mL and 11.68 μIU/mL respectively. High-throughput sequencing of the genetic endocrine disease gene Panel (412 detected genes, including 49 known diabetes-related genes) showed that the EIF2AK3 gene in the infant had two novel compound heterozygous mutations, c.2731_2732delAG and c.2980G>A, both of which were located in the kinase domain. The infant was diagnosed with Wolcott-Rallison syndrome (WRS). As a rare autosomal recessive disease, WRS is characterized by neonatal diabetes, multiple epiphyseal dysphasia and liver disease. Neonatal diabetes is a prerequisite for the diagnosis of WRS. The EIF2AK3 gene is the pathogenic gene of WRS.

Aesculus chinensis belongs to Hippocastanaceae family,bears medicinal and ornamental values. The oleanane type triterpenoid saponin aescin is regarded as active ingredient and accumulated in seed. In order to understand its molecular basis of the triterpenoid biosynthesis,we used high-throughput sequencing under Illumina Hi Seq 2000 platform to obtain the transcriptome data of seed and flower from A. chinensis to further mine the genes involved in its metabolic pathway. Unigene's de novo splicing was performed using Trinity software; the transcriptome results were annotated with KEGG database to predict the specific pathways of the aescin triterpenoid metabolism. Terpenoid and triterpenoid pathways were found from transcriptome data,and forty seven and twenty seven corresponding genes were uncovered respectively. It was found that there are eight kinds of enzymes related to the terpenoid metabolism pathway precursors and three kinds of enzymes related to the triterpenoid metabolism pathway. In this study,five genes corresponding to triterpene cyclase were analyzed in A. chinensis for the first time,which may participate in the synthesis of triterpenoid. It' s revealed that there were thirty three differential genes associated with the ko00900 and ko00909 pathways by analysis on the difference in transcriptome expression between seeds and flowers; seventeen unigenes were up-regulated and sixteen unigenes were down-regulated in the seeds relative to flowers. In this study, qRT-PCR experiments were used to verify the expression of three key enzyme genes of SQE( Unigene25806),HMGS( Unigene36710),and β-AS( Unigene33291). The results of qRT-PCR were consistent with the transcriptome data. The candidate genes related to triterpenoid saponin aescin synthesis in A. chinensis found in this study can provide theoretical basis for the metabolism synthesis and regulation of aescin.

OBJECTIVE:
To study the clinical characteristics, drug sensitivity of isolated strains, and risk factors of drug resistance in children with invasive pneumococcal disease (IPD).
METHODS:
The clinical characteristics and drug sensitivity of the isolated strains of 246 hospitalized children with IPD in nine grade A tertiary children's hospitals from January 2016 to June 2018 were analyzed.
RESULTS:
Of the 246 children with IPD, there were 122 males and 124 females. Their ages ranged from 1 day to 14 years, and among them, 68 (27.6%) patients were less than 1 year old, 54 (22.0%) patients were 1 to 2 years old, 97 (39.4%) patients were 2 to 5 years old, and 27 (11.0%) patients were 5 to 14 years old. Pneumonia with sepsis was the most common infection type (58.5%, 144/246), followed by bloodstream infection without focus (19.9%, 49/246) and meningitis (15.0%, 37/246). Forty-nine (19.9%) patients had underlying diseases, and 160 (65.0%) had various risk factors for drug resistance. The isolated Streptococcus pneumoniae strains were 100% sensitive to vancomycin, linezolid, moxifloxacin, and levofloxacin, 90% sensitive to ertapenem, ofloxacin, and ceftriaxone, but had a low sensitivity to erythromycin (4.2%), clindamycin (7.9%), and tetracycline (6.3%).
CONCLUSIONS
IPD is more common in children under 5 years old, especially in those under 2 years old. Some children with IPD have underlying diseases, and most of the patients have various risk factors for drug resistance. Pneumonia with sepsis is the most common infection type. The isolated Streptococcus pneumoniae strains are highly sensitive to vancomycin, linezolid, moxifloxacin, levofloxacin, ertapenem, and ceftriaxone in children with IPD.

OBJECTIVE:
To systematically evaluate the efficacy and safety of anterior decompression and posterior decompression in the treatment of thoracolumbar fractures with spinal cord injury, so as to provide a good scientific basis for more effective treatment of thoracolumbar fractures with spinal cord injury.
METHODS:
A clinical data about comparative study of anterior decompression and posterior decompression in the treatment of thoracolumbar fractures with spinal cord injury was searched and collected. The databases of Pubmed, Embase, Cochrane Library, CNKI, CBM, Wanfang Medical Network were searched by computer. Artificially collected journals included Spine, European Spine Journal, The Journal of Bone and Joint Surgery. Two spine surgeons independently screened the literature according to established inclusion and exclusion criteria and assessed the quality of the included studies. Meta-analysis was performed on the data using Review Manager 5.3 software, the indicators included operative time, intraoperative blood loss, postoperative tactile score, postoperative motor score, postoperative vertebral height, hospitalization time, neurological function recovery, efficiency of treatment, postoperative complications.
RESULTS:
Fifteen randomized controlled trials (RCTs) were enrolled in a total of 1 360 patients, including 680 anterior decompression and 680 posterior decompression. The results of Meta-analysis showed that the anterior decompression group had longer operation time [MD=80.09, 95% CI(36.83, 123.34), P=0.000 3], more intraoperative blood loss [MD=225.21, 95%CI(171.07, 279.35), <0.000 01], longer hospitalization time [MD=2.31, 95% CI(0.32, 4.31), P=0.02]. And the postoperative tactile score [MD=13.39, 95% CI(9.86, 16.92), <0.000 01], postoperative motor score [MD=13.15, 95% CI(7.02, 19.29), <0.000 1], vertebral height [MD=1.36, 95% CI(0.79, 1.92), <0.000 01] in anterior decompression were higher than that in posterior decompression. There was no statistically significant differences in the efficacy of treatment [OR=1.14, 95% CI(0.56, 2.31), P=0.72], neurological recovery [OR=0.87, 95% CI(0.57, 1.33), P=0.52] between two groups.
CONCLUSIONS
Compared with posterior decompression, the anterior decompression has the advantages of longer operating time, more intraoperative blood loss, longer hospitalization time, higher postoperative tactile score, higher postoperative motor score, and higher injury vertebral height, But there was no significant difference in the treatment efficiency and nerve function recovery between two groups.

Macrophages show significant heterogeneity in function and phenotype, which could shift into different populations of cells in response to exposure to various micro-environmental signals. These changes, also termed as macrophage polarization, of which play an important role in the pathogenesis of many diseases. Numerous studies have proved that Hesperidin (HDN), a traditional Chinese medicine, extracted from fruit peels of the genus citrus, play key roles in anti-inflammation, anti-tumor, anti-oxidant and so on. However, the role of HDN in macrophage polarization has never been reported. Additional, because of its poor water solubility and bioavailability. Our laboratory had synthesized many hesperidin derivatives. Among them, hesperidin derivatives-12 (HDND-12) has better water solubility and bioavailability. So, we evaluated the role of HDND-12 in macrophage polarization in the present study. The results showed that the expression of Arginase-1 (Arg-1), interleukin-10 (IL-10), transforming growth factor β (TGF-β) were up-regulated by HDND-12, whereas the expression of inducible Nitric Oxide Synthase (iNOS) was down-regulated in LPS- and IFN-γ-treated (M1) RAW264.7 cells. Moreover, the expression of p-JAK2 and p-STAT3 were significantly decreased after stimulation with HDND-12 in M1-like macrophages. More importantly, when we taken AG490 (inhibitor of JAK2/STAT3 signaling), the protein levels of iNOS were significantly reduced in AG490 stimulation group compare with control in LPS, IFN-γ and HDND-12 stimulation cells. Taken together, these findings indicated that HDND-12 could prevent polarization toward M1-like macrophages, at least in part, through modulating JAK2/STAT3 pathway.
