Objective:To describe the clinical features and immunological of Uygur systemic lupus erythematosus (SLE) subjects.Methods:Atotal of 484 adult patients (≥18 years) followed in the People's Hospital of the Xinjiang Uygur Autonomous Region were included into this study including 211 Uygur patients with SLE and 273 Han patients with SLE.Results:① Of the 211 Uygur SLE patients, 195 (92.4%) were female and 16(7.6%) were male (female:male=12.2∶1), the mean age at SLE onset was 15-64(35±12) years, mean disease duration was 0.1-228(21±35) months.② Of the 211 Uygur SLE patients, the most prevalent clinical presentationswere renal involvement 56.4%(119/211), hematological 56.4%(119/211), rash 50.2% (106/211), arthralgia/arthritis 49.8%(105/211), weakness 47.9%(101/211). The significant difference observed between the Uygur and Han SLE patients was Raynaud phenomenon( χ2=6.066, P=0.014) .③ The positive rates of antinuclear antibodies were 94.8%(200/211), 54.5%(115/211) for anti-dsDNA antibodies, 47.9% (101/211) for anti-SSA antibodies, 35.1%(74/211) for anti-U 1-RNP antibodies, and 28.4%(60/211) for anti-AHA antibodies. The positivity of anti-AHA antibodies ( χ2=4.952, P=0.026) was higher in Uygur SLE patients than thatin Han SLE patients. More Uygur SLE patients were anemic ( χ2=6.904, P=0.009), with decrease of complement ( χ2=6.330, P=0.012). Conclusion:This study can not find any significant differences between the Uygur SLE patients and Han SLE patients in common clinical manifestations in Xinjiang. The Uygur SLE patients are more likely to have anemia and decrease of complement, which may be related to race and diet habits.

Objective Primitive neuroectodermal tumor (PNET) is a rare malignant small round cell tumor .This paper aimed to study the clinical and pathological features of primary pulmonary primitive neuroectodermal tumor . Methods We collected 2 cases of primary pulmonary PNET to review the clinical and pathological features .Immunohistochemical staining was used to detect immune mark-ers, and fluorescence in situ hybridization (FISH) was applied to detect EWS translocation. Results 2 patients were aged 33 years and 17 years.Microscopically, the tumor cell was composed of single small round cells in diffusion or in distribution of sheets or beams , with scant cytoplasm , oval or spindle-shaped nucleus , high mitotic count .Irregular tumor necrosis scattered in the tumor along with visi-ble rosette structure.Immunohistochemical study showed that the tumor cells were positive for CD 99, FLI-1 and Syn, while CKpan, EMA, Desmin, CgA, TTF1, CD34 were negative.EWS/FLI1 translocations were detected positive in both the cases .2 patients died 7 months and 32 months after operation , respectively . Conclusion Primary pulmonary PNET is rare , so the selection of appropriate im-mune markers (CD99, FLI-1, Syn) and FISH for the detection of EWS translocation helps to improve the accuracy of diagnosis .

Objective: Fungal keratitis is one of the most common diseases leading to blindness.It has a high incidence in China,and its early diagnosis and treatment are of vital importance.We aimed to investigate the value of laser confocal corneal microscopy in the clinical diagnosis of fungal keratitis.Methods: We conducted laser confocal corneal microscopy on 37 patients suspected of fungal keratitis,and compared the results with those obtained from the corneal tissue smears and fungal cultivation.Results: The fungus-infected corneas histologically exhibited defected epithelial cells,damaged subepithelial nerves and disordered stroma with reduced transparence.The hyphae showed bright,disordered,interlaced thread-or short rod-like structures.The positive rates of smear examination,fungus cultivation and laser confocal corneal microscopy were 48.65,62.16 and 78.39% for the 37 eyes,75.00,87.50 and100% for the 16 untreated eyes,and 28.57,42.85 and 61.90% for the other 21 pretreated eyes.Conclusion: Confocal laser corneal microscopy,rapid,effective and noninvasive,can be used as an important new alternative in the diagnosis of fungal keratitis

Objective To determine whether color doppler ultrasonography (CDU),thyroid function or thyroid autoimmune antibodies could identify Graves' disease in pregnancy(GDP) in pregnant patients with newly diagnosed thyrotoxicosis.Methods It is an observational study.Sixty-eight pregnant patients with newly diagnosed thyrotoxicosis including gestational hyperthyroidism (GHT) subjects (GHT group,n =33) and GDP subjects (GDP group,n =35),and 62 age-and sex-matched healthy subjects (C1 group:pregnant,n =32,C2 group:non-pregnant,n =30) were recruited.Thyroid function,human chorionic gonadotropin(HCG),thyroid autoimmune antibodies were detected.Peak systolic velocity of the superior thyroid artery (STA-PSV) and diastole inner diameter(STA-D) of the superior thyroid artery were measured by CDU.A ROC curve was used to evaluate STA-PSV,STA-D,thyroid function and thyroid autoimmune antibodies for identification of GDP.Results The area under the ROC curve of STA-PSV,STA-D and thyroid stimulating hormone (TSH),free T4 (FT4) for GDP were 0.905,0.887,0.803 and 0.786,respectively.The optimal cut-off points of STA-PSV,STA-D,TSH and FT4 for GDP were 40 cm/s,2.0mm,0.03 mIU/L and 30 pmol/L with the sensitivity of 82.9％,72.1％,81.8％,76.2％ and specificity of 81.8％,87.9％,75.2％,80.3％,respectively.Conclusions Detection of STA-PSV and STA-D by CDU,as well as thyroid function,is useful in screening GDP in pregnant patients with thyrotoxicosis.

Objective To detect the pathological state of metabolic syndrome and the expression of microRNA-205 in women with endometrial cancer.Methods Thirty-eight cases of patients with endometrial cancer were collected including waist circumference,weight,blood pressure.Collected preoperative fasting blood,postoperative endometrial lesions and endometrium tissue adjacent to carcinoma paraffin section.Analyzed the metabolic syndrome in patients with pathological state indicators,extracted the total RNA of endometrium tissue and the level of microRNA-205 was detected.Results The prevalence of metabolic syndrome was 44.74％ (17/38).The abnormal rate of high-density lipoprotein cholesterol,blood pressure,triglycerides,waist circumference,fasting blood sugar successively were 52.6％ (20/38),36.8％ (14/38),34.2％ (13/38),34.2％ (13/38) and 26.3％ (10/38).The expression level of microRNA-205 in endometrial carcinoma was higher than that in normal endometrium tissues,there was significant difference (P ＜ 0.01).Conclusions Metabolic syndrome is closely associated with the metabolic syndrome and its components.The expressions of microRNA-205 may participate in the occurrence and development of endometrial carcinoma,and it may be as an early screening of molecular markers.

Objective To evaluate left atrial (LA) function by real-time three-dimensional echocardiography (RT-3D) and speckle tracking imaging (STI) after circumferential ablation of pulmonay vein ostia for atrial fibrillation guided by carto mapping system. Methods Thirty patients who had ablation procedure for paroxysmal atrial fibillation were accepted echocardiography to estimate the LA function at pre-operation,3 days and 3 months of post-operation. The LA maximal, minimal and pre-systolic volume (LAVmax, LAVmin and LAVp), LA passive ejection fraction (LAPEF), LA active ejection fraction (LAAEF) were measured by RT-3DE respectively. The strain rate curve was acquired in each LA segment (anterior, posterior, lateral, inferior and septal) by STI. Systolic strain rate (SRs), early diastolic strain (SRe) and late diastolic strain rate(SRa) of each left atrial segments were measured. Results Comparing with preoperative,3 days post-ablation SRs,SRe and SRa decreased significantly in each wall of LA. After 3 months,SRa and SRe in anterior, inferior and septal were significantly improved, however, SRs showed no significant difference. LAVmax and LAVpre were significantly decreased. LAPEF and LAAEF were significantly improved. Conclusions The patients with circumferential pulmonary vein ablation were in a deterioration after three days. The pump function and conduit functions of left atrial were increased after 3 months.

Objective　To provide data support for the prevention and control of melioidosis by analyzing epidemiological characteristics of melioidosis bloodstream infection and antibiotic resistance of its pathogen in Hainan Province from 2012 to 2021. Methods Data was collected from Hainan Antimicrobial Resistance Surveillance System, and WHONET 5.6 software was used to merge and analyze data. Results The case numbers of melioidosis bloodstream infection showed an increasing trend year by year from 2012 to 2021. The ratio of male to female patients was 4.6∶1, with 347 cases (58.91%) of patients aged 40-<60, the age group with the highest incidence. The number of cases from July to November were 424 cases (72.0%). Haikou and Sanya reported the largest case number, with 261 and 116 cases respectively. But there were no case reported from central area including Chengmai, Tunchang, Qiongzhong and Baoting. Burkholderia pseudomallei strains were isolated from both blood and other specimens in 105 of the 589 patients, with respiratory tract and wood specimens being the sites with the highest number of strains isolated other than blood; the resistance rates of Burkholderia pseudomallei to five antibiotics showed no obvious trend of change, with the lowest resistance rate to imipenem among the five drugs at 0.6%, followed by ceftazidime at 2.2%. Conclusion During the typhoon season, elderly, middle-aged male in coastal areas should pay attention to avoid or reduce their contact with mud and water. For patients with melioidosis bloodstream infection, imipenem or ceftazidime should be selected as early as possible for initial treatment.
