Artificial intelligence (AI) has been widely used in all walks of life, including healthcare, and has shown great application value in the auxiliary diagnosis of pulmonary nodules in the medical field. In the face of a large amount of lung imaging data, clinicians use AI tools to identify lesions more quickly and accurately, improving work efficiency, but there are still many problems in this field, such as the high false positive rate of recognition, and the difficulty in identifying special types of nodules. Researchers and clinicians are actively developing and using AI tools to promote their continuous evolution and make them better serve human health. This article reviews the clinical application and research progress of AI-assisted diagnosis of pulmonary nodules.

OBJECTIVE: Xiaotan Sanjie recipe (XTSJ), a Chinese herbal compound medicine, exerts a significant inhibitory effect on gastric cancer (GC) metastasis. This work investigated the mechanism underlying the XTSJ-mediated inhibition of GC metastasis. METHODS: The effect of XTSJ on GC metastasis and the associated mechanism were investigated in vitro, using GC cell lines, and in vivo, using a GC mouse model, by focusing on the expression of Glc-N-Ac-transferase V (GnT-V; encoded by MGAT5). RESULTS: The migration and invasion ability of GC cells decreased significantly after XTSJ administration, which confirmed the efficacy of XTSJ in treating GC in vitro. XTSJ increased the accumulation of E-cadherin at junctions between GC cells, which was reversed by MGAT5 overexpression. XTSJ administration and MGAT5 knockdown alleviated the structural abnormality of the cell-cell junctions, while MGAT5 overexpression had the opposite effect. MGAT5 knockdown and XTSJ treatment also significantly increased the accumulation of proteins associated with the E-cadherin-mediated adherens junction complex. Furthermore, the expression of MGAT5 was significantly lower in the lungs of BGC-823-MGAT5 + XTSJ mice than in those of BGC-823-MGAT5 + solvent mice, indicating that the ability of gastric tumors to metastasize to the lung was decreased in vivo following XTSJ treatment. CONCLUSION XTSJ prevented GC metastasis by inhibiting the GnT-V-mediated E-cadherin glycosylation and promoting the E-cadherin accumulation at cell-cell junctions.

Objective To investigate the difference of matrix stiffness in different regions of tibial plateau in osteoarthritis (OA) and its effects on morphology of the cartilage and mitochondria. Methods The tibial plateau cartilage specimens of OA were obtained for nanoindentation test, transmission electron microscopy and histological analysis. The stiffness of cartilage matrix in different regions of OA tibial plateau was detected by nano-indentation. The morphology of cartilage mitochondria in different regions was observed by transmission electron microscopy, and the changes of mitochondrial plane area, shape and ridge volume density were quantitatively analyzed. Cartilage injury in different regions of OA tibial plateau was observed by histological staining. Results The cartilage of OA tibial plateau showed regional heterogeneity, and the cartilage and mitochondria on medial side of varus knee OA were more severe, and the matrix stiffness was higher. The OA scores were positively correlated with matrix stiffness. There was also a significant correlation between OA scores and mitochondrial morphology: the higher OA scores, the larger and rounder mitochondrial plane area, and the lower cristae volume density. Conclusions The differences of tibial plateau revealed the correlation between cartilage matrix stiffness, OA scores and mitochondrial morphological parameters. The increased cartilage matrix stiffness may be the main cause of chondrocyte mitochondrial injury, and further aggravate the progression of OA.

Langerhans cell histiocytosis(LCH)and Langerhans cell sarcoma(LCS)are characterized by clone proliferation of Langerhans-type cells, which may occur concurrently or sequentially with T-cell acute lymphoblastic leukemia (T-ALL) and other Lymphoid neoplasms. A 15-year old female patient diagnosed with T-ALL developed LCH involving multiple systems during maintenance chemotherapy of T-AL. After treated with chemotherapy with improved result, the patient showed progression of the illness and refractory to the second-line treatment. We found c.G35A (p.G12D)mutation in the KRAS gene and used the targeted drug Trametinib for treatment. The treatment proved effective, leading to partial remission within a week. Three months after Trametinib treatment, the patient developed new lymphadenopathy. Biopsy revealed the existence of LCS. The disease progressed quickly, and the patient died 7 days after diagnosis of LCS. The case of patients with T-ALL then developing LCH and LCS sequentially is extraordinarily rare. The causes of the case is unclear and may be related to cell transdifferentiation, clonal evolution, and chemotherapy. Targeted drugs can contain this disease for a short time.

Objective:To evaluate the clinical efficacy and safety of Longmu Zhuanggu granule for the treatment of children recurrent respiratory infection due to lung-spleen Qi deficiency. Method:This multicenter stratified， block-randomized， double-blind， double-dummy， positive drug （pidotimod granule） parallel controlled， and non-inferiority trail intended to included 240 children patients and divided them into the experimental group （n=120） and the control group （n=120） at the ratio of 1∶1. Patients in both groups were treated for eight successive weeks and followed up for 12 months. The cure rates， numbers of respiratory infections， average courses of disease， curative effects of traditional Chinese medicine （TCM） syndrome， curative effects of individual symptoms， curative effects of immune indexes， and safety indexes between the two groups were observed and compared. Result:A total of 237 subjects were collected from 10 research centers， including 119 cases in the control group and 118 in the experimental group. There were 236 cases enrolled into the full analysis set （FAS）， 210 into the per-protocol set （PPS）， and 236 into the safety set （SS）. The baseline data of the two groups were not significantly different from each other， indicating that they were comparable. The cure rates of the experimental group and control group were 75.21% （88/117） and 73.95%（88/119）， respectively， with the 95% confidence interval （CI） of difference between the two groups being 1.26% （-9.85%，12.37%） for FAS and 3.81% （-6.28%，13.90%） for PPS. The 95% CI fell within the 10% non-inferiority margin， implying that non-infertility test of the cure rate in the treatment of endpoint disease was valid， and the conclusions of FAS and PPS analysis were consistent. There was no significant difference in the number or course of upper respiratory infection， bronchitis， and pneumonia. The difference in curative effects of TCM syndrome between the two groups after four weeks of treatment was not remarkable. After eight weeks of treatment， the total effective rate of the experimental group was 84.62%（99/117）， statistically higher than 78.15%（93/119） of the control group（χ²=-3.26，P<0.05）. There were no significant differences in the disappearance rates of individual symptoms between the two groups after four weeks of treatment. After eight weeks of treatment， the experimental group and control group exhibited the disappearance rates of 67.50%（54/80） and 47.37%（36/76） for shortness of breath and laziness to speak， 75.00%（54/72） and 53.33%（40/75） for poor appetite， 54.55%（60/110） and 37.84%（42/111） for hyperhidrosis， respectively， with obviously better outcomes observed in the experimental group （P<0.05，P<0.01）. The inter-group comparison revealed significant differences in immune indexes after eight weeks of treatment. As demonstrated by comparison with the situations before treatment， IgA， IgG， IgM， and CD4 did not change significantly after treatment. Except for CD8 in the experimental group (P<0.05), there was no significant difference in other immune indexes before and after treatment There was no significant difference in the incidence of adverse reactions. Conclusion:Longmu Zhuanggu granule is not inferior to pidomod granule in the treatment of children recurrent respiratory infection due to lung-spleen Qi deficiency， and it exhibits good safety， implying its promising clinical application value.

Wiskott-Aldrich syndrome (WAS) is also called immunodeficiency syndrome complicated with eczema and thrombocytopenia, which is a rare X-linked primary immunodeficiency disease.Mutations in the WAS gene causes the deficiency of WAS protein, impairing normal functions of T and B lymphocytes, and thereby leading to the clinical manifestations of WAS.Hematopoietic stem cell transplantation (HSCT) is the only effective treatment for WAS patients currently.However, HSCT also has disadvantages of few human leucocyte antigen (HLA) matched donors, the risk of graft versus host disease and immune system disorders.With the development of gene editing technology, multiple studies have established that gene therapy is a promising therapy for WAS.In this study, recent research on the application of gene therapy in WAS were reviewed to promote clinicians′ understanding of gene therapy in the management of WAS.

Visual fixation is an item in the visual function subscale of the Coma Recovery Scale-Revised (CRS-R). Sometimes clinicians using the behavioral scales find it difficult to detect because of the motor impairment in patients with disorders of consciousness (DOCs). Brain-computer interface (BCI) can be used to improve clinical assessment because it directly detects the brain response to an external stimulus in the absence of behavioral expression. In this study, we designed a BCI system to assist the visual fixation assessment of DOC patients. The results from 15 patients indicated that three showed visual fixation in both CRS-R and BCI assessments and one did not show such behavior in the CRS-R assessment but achieved significant online accuracy in the BCI assessment. The results revealed that electroencephalography-based BCI can detect the brain response for visual fixation. Therefore, the proposed BCI may provide a promising method for assisting behavioral assessment using the CRS-R.

Objective: To compare the safety and efficacy of pulsed dye laser (PDL) with different sessios for the East Asian infants with port-wine stains(PWS). Methods: From September 2016 to September 2017, 24 East Asian infants with untreated PWS, who met the standards of enrollment, received seven treatments by PDL at 2-week intervals and three treatments at 6-week intervals at adjacent locations in each patient 2 months after final treatment. The efficacy outcome was compared with Wilcoxon signed-rank test, while the safety was compared using Fisher′s exact test. Results: Of the 24 patients, 20 completed study. Seven patients had multiple sites, given a total of 62 treated PWS sites. Among the patients, 18 had lesions on the face and 2 on the extremities. The average blanching rate was (43.71 ± 27.16) % and (43.29 ± 31.58) % for PDL treatments with 7- and 3- sessions, respectively (P>0.05). The result was consistent with independent observer assessment judging that the result of 7 laser treatments was equally with that of 3 treatments (r=0.416, P=0.0008). The average grade was 3.58 ± 1.21 and 3.53 ± 1.16 for 7- and 3-sessions. The patients treated with 7-sessions developed a little more side effects than 3-sessions, including residue purpura, pigmentation changes, eczema and dermatitis. Conclusions After three treatments of PDL, the efficacy may not necessarily increased by more frequent treatments for East Asian infantile PWS.

OBJECTIVETo validate the clinical relationship between miR-182 and glucocorticoid-resistance in patients with lymphoid malignancy.

METHODSReal-time quantitative PCR(qRT-PCR) was employed to detect the expression of miR-182 in lymphoma patients (68 cases, the specimens indluded bone marrow of 20 cases, and plasma of 48 cases), multiple myeloma patients (24 cases, the specimens included bone marrow of 14 cases and plasma of 10 cases), ALL patients (3 cases, specimen was plasma of 3 cases) and non-lymphotic system disorder patients (18 cases, specimens included bone marrow of 8 cases and plasma of 10 cases).

RESULTSThe expression of miR-182 in refractory lymphoblastic tumor patients was significantly higher than that in initial treatment group (P<0.05); the expression of miR-182 in initial treatment patients was not significantly different from the controls. The expression level of miR-182 in plasma of lymphoid malignancy patient significantly correlated with their used dosage of corticosteroids (P<0.05). When the expression level of miR-182 in bone marrow cells was 10.09, its sensitivity and specificity for diagnosis were 100% and 88.2% respectively; when the expression level of miR-182 in plasma was 1.393, its sensitivity and specificity for diagnosis of glucocorticoid resistance of lymphoblastic tumor cells were 90.9% and 51.3% respectively.

CONCLUSIONThe expression of miR-182 in lymphoblastic tumor with glucocorticoid resistance is significantly up-regulated, suggesting that the glucocorticoid resistance of lymphoblastic tumor is related with the over-expression of miR-182. The miR-182 is expected as a new biomarker for the diagnosis of glucocorticoid resistant lymphoblastic tumor.

Objective To determine collateral circulation in patients with acute ischemic stroke using capillary index score (CIS)in order to evaluate the prognosis of endovascular treatment. Methods From January 2013 to December 2015,46 consecutive patients with acute ischemic stroke treated with endovascular treatment at the Department of Neurology,Central Hospital of Baotou were enrolled retrospectively. Angiography was performed before endovascular treatment in order to complete CIS score. The patients were divided into a good prognosis group (n = 21)and a poor prognosis group (n = 25)according to the modified Rankin scale (mRS)scores. Univariate analysis was used to compare the baseline data and the clinical data of the two groups,including age,sex,history of diabetes,pretreatment systolic blood pressure,conducting intravenous thrombolysis or not,time from ictus to intravenous thrombolysis,National Institutes of Health Stroke Scale (NIHSS)score,Alberta stroke program early CT score (ASPECTS),vascular filling,time from onset to revascularization,and postoperative vascular recanalization (the modified Thrombolysis in Cerebral Infarction [mTICI]). Multivariate analysis was used to analyze the effect of CIS score on good prognosis. Results There were no significant differences in age,sex,history of diabetes,pretreatment systolic blood pressure,conducting intravenous thrombolysis or not,time from ictus to thrombolysis,and number of mechanical thrombectomy between the good prognosis group and the poor prognosis group (all P > 0. 05). There were significant differences in the NIHSS score (15 ± 3 vs. 19 ± 4),ASPECTS score (8 [7,10]vs. 6 [5,8]),filling well 85. 7% (18 / 21)vs. 44. 0% [11 / 25]),time from ictus to recanalization (363 ± 42 min vs. 398 ± 53 min),and postoperative vascular recanalization (mTICI≥Ⅱb)(100. 0% [21 / 21]vs. 68. 0%[17 / 25];all P < 0. 05). CIS (OR,8. 600,95% CI 2. 670 -33. 800)and mTICI grade (OR,5. 720, 95%CI 12. 170-22. 300)were significantly associated with the prognosis. Conclusion The CIS score can be used to evaluate brain perfusion. fCIS is closely associated with the good clinical prognosis. When screening the suitable patients for endovascular therapy,increasing the CIS score to evaluate the salvageable brain tissue is effective and feasible.
