Humanized medical service should take Benevolence as the goal and run throughout the whole process of diagnosis and treatment of rheumatic immune diseases.Through the discussion on improving doctors' medical skills and paying attention to patients' mental health and physiological needs in the department of rheumatology and immunology,this paper put forward that it should improve the patient's disease control rate,prolong the survival,improve the quality of life and build a harmonious relationship between doctors and patients through the humanized treatment program,health education and follow-up.

A total of 16 patients with airway stenosis including benign lesion (n=4) and malignant disease (n=12) were treated with argon plasma coagulation (APC) and Z-type covered retrievable metallic stent.L-and I-type stents were placed by guidance of brenchoscope,while Y-type stent was placed by the guidance of both bronchoscope and fluoroscope.Airway stenosis was from (58.8 +9.1)% before APC to (7.5±2.4)% after APC in tracheal,from (67.4±7.4)% to (19.4±4.1)% in left main bronchus,from (69.6±8.9)% to (27.6±5.4)% in right main bronchus.Symptoms of chest distress and breathlessness were improved remarkably,tachypnea indexes were decreased,but Kamofsky performance scope were increased.Twelve stents were successfully installed by the first time,including 9 Y-shape;otherwise,4 stents failed to be installed because the carinal was too wide to insert the Y-shape stent in two patients with lung cancer,finally,L+I type stents were used.Median survival time after successful stenting was 10 months,and mean time was 13 months.APC combined with bifurcated metal stants relieved obstruction and improved quality of life.

Objective To investigate the clinical characteristics of patients with polymyositis(PM) and dermatomyositis (DM), and compare the differences of PM/DM to help the understanding of clinical diagnosis and treatment. Methods One hundred and forty-five hospitalized PM/DM patients from Department of Rheumatology of the First Affiliated Hospital of Xiˊan Jiaotong University were collected from May 2008 to December 2014, and the clinical manifestations, muscle enzymes, electromyogram, muscle biopsy, treatment outcome were retrospectively analyzed. Mann-Whitney U test and χ2 test were used for statistical analysis. Results The most common initial symptom of PM was muscle weakness, accounted for 51.2%, while rash was the initial presentation in most DM patients(43.1%). The incidence of interstitial lung disease (ILD) (62.7% vs 39.5%, χ2=11.009, P=0.001), and the elevation of CRP (48.9% vs 26.8%, χ2=10.272, P=0.001) were all higher in DM than PM, while the elevation of level of CK (85.4% vs 61.8%, U=-2.668, P=0.008) and CKMB (82.9%vs 41.2%, U=-3.303, P=0.001) were more common in PM compared with DM. The pathological study showed degeneration of muscle fiber, connective tissue hyperplasia in most PM patients, and perimysium atrophy, vacuoles degeneration, muscle bundles, perivascular inflammatory cell infiltration were observed in most DM patients. During the follow-up, the clinical remission rate was 57.5%, the relapse rate and the mortality rate was 7.5%and 31.1%respectively. The mortality rate was higher in DM than PM (34.6% vs 21.4%, χ2=4.861, P=0.027). Infection and tumors were the major causes of death, and the lung was the most common site of infection. Conclusion Differences in the clinical features, muscle enzymes, CRP level, pathology and the mortality rate between PM and DM are evident, while ILD, infection and the higher mortality rate are more common in DM than in PM.

Objective To investigate the affect of body positions on biochemical indexes. Methods By autogenous contrast and cross matched survey, 107 volunteers divided into 3 season patches of winter, spring and summer, blood samples were drawn from the same part in both standing and lying positions。From19 persons, blood samples were collected respectively after standing and sitting for 15 min, lying for 15 min and 30 min and then sitting for another 15 min。 The blood samples were analyzed for 32 biochemical indexes on analyzer。Results 25 biochemical indexes in sitting position were significantly different from those in lying position (P0。05)。Conclusions Changing body position can result in obvious physiological variation of 28 biochemical indexes, particularly of those related to protein. Such result may lead to abnormality in some marginal values. It suggests body position should not be neglected in analyzing laboratory data.

BACKGROUND AND OBJECTIVETranscatheter arterial chemotherapy and embolization is the main method in the treatment of lung cancer, but most of the reports do not study individually to small cell lung cancer (SCLC), non-small cell lung cancer (NSCLC), hypovascular and hypervascular lung cancer. The pre-embolization perfusion of hemotherapeutics is still being used routinely and seldom report to iodized oil embolization. The article summarized the quality of life after the treatment, clinical efficiency, survival time and complications to evaluate the clinical effect of primary hypervascular NSCLC treated with embolization of emulsion of chemotherapeutics and iodized oil.

METHODSThe study totally analyzed 41 cases which confirmed by pathology and follow up study from January, 2008 to January 2009. The CT scan with IV contrast demonstrates over moderate enhanced lesion which indicate hypervascular. Within the 41 cases, 23 cases of central, 18 cases of peripheral. Suqamous carcinoma 21 cases, adenocarcinoma 15 cases and squamoadenocarcinoma 5 cases. Stage IIIb 34 cases, stage IV 7 cases. Superselective incubation with microcatheter under DSA, to embolize the capillary bed with liquefied iodized oil and the emulsion of pharmorubicin, to embolize the supply artery of the tumor with gelatin foam microparticle. The liquefied iodized oil 5 mL-10 mL, pharmorubicin 10 mg-30 mg. The longest follow up is 12 months and to compare with the references of 2007-2009.

RESULTSThe KPS is widely acclaimed after the treatment (P < 0.05), no complete response (CR), 31 cases of partial response (PR), 7 cases of no change (NC) and 3 cases of progressive disease (PD), the total efficiency (CR+PR) is 75.6%. The clinical efficiency (CR+PR+NC) is 92.68%. 33 cases of total survival tome over 12 months (80.48%), IIIb stage 29/34 (85.29%), IV stage 4/7 (57.14%). 1 case with severe complication-spinal injury.

CONCLUSIONTo treat primary hypervascular NSCLC with simple embolization of emulsion of chemotherapeutics and iodized oil is very useful and can avoid the side effect of chemotherapeutics. The key point to avoid spinal injury and other severe complications is to distinguish the spinal aretery and intratumor AV fistula by using superselective incubation with microcatheter under DSA.

BACKGROUND AND OBJECTIVETACE, Ar-He target cryosurgery and radioactive seeds implantation are the mainly micro-invasive methods in the treatment of lung cancer. This article summarizes the survival quality after treatment, the clinical efficiency and survival period, and analyzes the advantages and shortcomings of each methods so as to evaluate the clinical effect of non-small cell lung cancer with multiple minimally invasive treatment.

METHODSAll the 139 cases were non-small cell lung cancer patients confirmed by pathology and with follow up from July 2006 to July 2009 retrospectively, and all of them lost operative chance by comprehensive evaluation. Different combination of multiple minimally invasive treatments were selected according to the blood supply, size and location of the lesion. Among the 139 cases, 102 cases of primary and 37 cases of metastasis to mediastinum, lung and chest wall, 71 cases of abundant blood supply used the combination of superselective target artery chemotherapy, Ar-He target cryoablation and radiochemotherapy with seeds implantation; 48 cases of poor blood supply use single Ar-He target cryoablation; 20 cases of poor blood supply use the combination of Ar-He target cryoablation and radiochemotheraoy with seeds implantation. And then the pre- and post-treatment KPS score, imaging data and the result of follow up were analyzed.

RESULTSThe KPS score increased 20.01 meanly after the treatment. Follow up 3 years, 44 cases of CR, 87 cases of PR, 3 cases of NC and 5 cases of PD, and the efficiencywas 94.2%. Ninety-nine cases of 1 year survival (71.2%), 43 cases of 2 years survival (30.2%), 4 cases with over 3 years survival and the median survival was 19 months. Average survival was (16 +/- 1.5) months. There was no severe complications, such as spinal cord injury, vessel and pericardial aspiration.

CONCLUSIONMinimally invasive technique is a highly successful, micro-invasive and effective method with mild complications. To non-small cell lung cancer, we can improve the middle and long term clinical effect by using the different combination of multiple minimally invasive treatments according to the patient's condition.

Objective:To investigate the clinical characteristics of E. coli peritoneal dialysis-associated peritonitis (PDAP) and the risk factors for its occurrence and treatment failure.Methods:The clinical data of patients with episodes of PDAP in four general hospitals in Jilin Province from 2013 to 2019 were retrospectively reviewed. According to the pathogenic bacteria, the patients were divided into E. coli and non- E. coli groups. The incidence of E. coli PDAP in the last seven years was calculated and the clinical characteristics were compared between two PDAP groups. Logistic regression was used to analyze the risk factors for the occurrence and treatment failure of E. coli PDAP. Results:A total of 693 PDAP episodes/cases were enrolled in this study, including 100 episodes/cases in the E. coli group and 593 episodes/cases in the non- E. coli group. The incidence rate of E. coli PDAP in the four hospitals showed a decreasing trend during 2013 to 2019. Compared with the non-E.coli group, the proportion of diabetic patients and the average blood albumin levels in the E. coli group were lower ( χ2=5.006, Z=-2.992, P<0.05), while the proportion of refractory peritonitis was higher, and the duration of antibiotic therapy was longer ( χ2=6.350, Z=-2.779, P<0.05). Multivariate Logistic regression analysis showed that history of PDAP ( OR=1.577, 95% CI: 1.015-2.448) and low baseline serum albumin level ( OR=0.958, 95% CI: 0.923-0.995) were independent risk factors for the development of E. coli PDAP, while concomitant diabetes was an independent protective factor for E. coli PDAP ( OR=0.538, 95% CI: 0.330-0.876). Moreover, long-term dialysis was an independent risk factor for treatment failure of E. coli PDAP ( OR=1.047, 95% CI: 1.018-1.076). Conclusion:The incidence rate of E. coli PDAP in study institutions has declined in the past 7 years, but the rate of refractory PDAP is still high. The history of PDAP and low blood albumin level are independent risk factors for the occurrence of E. coli PDAP, while concomitant diabetes is an independent protective factor for the occurrence of E. coli PDAP. Long-term dialysis is an independent risk factor for treatment failure of E. coli PDAP.

Objective:To investigate the effect of systemic lupus erythematosus (SLE) on the status of hepatitis B virus (HBV) infection, and provide data for clarifying the relationship between autoimmunity and infection.Methods:SLE patients in the department of rheumatology and immunology of the First Affiliated Hospital of Xi'an Jiaotong University from January 2016 to December 2019 were screened. A retrospective case-control study was carried out. SLE patients with positive hepatitis B surface antigen (HBsAg) were gender and age matched with chronic hepatitis B (CHB) in a 1∶4 ratio. Chi-square test was used to compared the positive rates of hepatitis B e antigen (HBeAg) and Paired-Samples t test or Signed rank Wilcoxon test was used to compare the HBV DNA load and HBsAg titer. Results:The positive rate of HBsAg in SLE patients was lower than the prevalence rate of HBsAg in general population in the second Chinese National Hepatitis Seroepidemiological Survey in 2006 [2.2%(27/1 227) vs 7.2%], but the positive rate of HBcAb was not obviously different from that in general population in China [33.9%(416/1 227) vs 34.1%]. Compared with matched CHB patients, the positive rate of HBeAg [37.0%(10/27) vs 58.3%(63/108), χ2=3.94, P=0.047], the HBV DNA load [0(0, 3.7) lg U/ml vs 4.8(2.2, 3.7) lg U/ml, Z=-5.37, P<0.001] and HBsAg titer [(2.0±1.5) lg U/ml vs (3.3±1.1) lg U/ml, t=-4.26, P<0.001] in SLE patients were lower. Conclusion:The HBV infection status of SLE patients is different from that of patients with chronic hepatitis B and the HBV infection is more likely to be controlled.

OBJECTIVE: To evaluate the association of GRIK2 and NLGN1 with autism spectrum disorder in a Chinese population. METHODS: We performed spatio-temporal expression analysis of GRIK2 and NLGN1 in the developing prefrontal cortex, and examined the expression of the genes in ASD cases and healthy controls using the GSE38322 data set. Following, we performed a case-control study in a Chinese population. RESULTS: The analysis using the publicly available expression data showed that GRIK2 and NLGN1 may have a role in the development of human brain and contribute to the risk of ASD. Later genetic analysis in the Chinese population showed that the GRIK2 rs6922753 for the T allele, TC genotype and dominant model played a significant protective role in ASD susceptibility (respectively: OR=0.840, p=0.023; OR=0.802, p=0.038; OR=0.791, p=0.020). The NLGN1 rs9855544 for the G allele and GG genotype played a significant protective role in ASD susceptibility (respectively: OR=0.844, p=0.019; OR=0.717, p=0.022). After adjusting p values, the statistical significance was lost (p>0.05). CONCLUSION: Our results suggested that GRIK2 rs6922753 and NLGN1 rs9855544 might not confer susceptibility to ASD in the Chinese population.
