Objective To investigate the effect of high flux dialysis mode on the improvement of β2-microglobulin clearance and hypertension in maintenance hemodialysis (MHD) patients. Methods Patients who received MHD at the Blood Purification Center of Xintang Hospital, Zengcheng District, Guangzhou from September 1, 2018 to October 31, 2018 (except for long-term low-flux dialysis patients due to self-tolerance factors)were selected. Random number table method was used to divide the patients into two groups,20 patients in each group. The control group received low flux hemodialysis, and the observation group received high flux hemodialysis. The treatment effects of the two groups were compared, levels of β2-microglobulin (β2-MG), intact parathyroid hormone (iPTH), changes in heart rate and blood pressure, and statistics on cardiovascular disease in the two groups before and after treatment at 3, 6, 12, and 18 months were recorded. Results The total effective rate in the observation group was 95.00%, which was higher than the 20.00% in the control group (P<0.05). After treatment, the levels of β2-MG and iPTH of the two groups decreased, and the observation group [(13.02±2.10) mg/L, (210.13±18.12) ng/L] was lower than the control group [(19.78±2.37) mg/L, (289.41±17.02)ng/L]; the β2-MG clearance rate of the observation group was higher than that of the control group at 3 months, 6 months, 12 months, and 18 months (P<0.05).Compared with that before treatment, the average arterial pressure and systolic blood pressure of the two groups were reduced, and the observation group was lower than that of the control group (P<0.05); the differences between diastolic blood pressure and systolic blood pressure at each time point in the control group were not significant (P>0.05); the 24-hour diastolic blood pressure and systolic blood pressure of the observation group decreased after 1, 3, 6, 12 and 18 months, compared with those before treatment (P<0.05), and were lower than those in the control group (P＜0.05).Comparison of the incidence of cardiovascular disease between the two groups: 1 case in the observation group was hospitalized for acute myocardial infarction; 2 cases in the control group were hospitalized for heart failure and 1 case was hospitalized for acute coronary syndrome; complications incidence in the two groups were compared (P>0.05). Conclusion The high flux dialysis mode can effectively improve the treatment outcomes of MHD patients, effectively remove blood toxins, lower blood pressure, and reduce the incidence of complications. It can be used in clinical practise.

Objective To summarize the application experience of a new technique in mediastinal infection after cardiac operation. Methods A retrospective analysis of adult patients with mediastinal infection after cardiac surgery from February 2017 to June 15, 2019 were taken including a total of 5 cases (1.2%), of which 4 were male and 1 was female, with an average age (49±19) years old, average weight (70±15) kg;2 cases had acute type A aortic dissection, 2 cases had coronary heart disease, 1 case had infective endocarditis with Behcet's disease. After diagnosed, the patients developed severe wound infection and excessive secretion. VSD (vacuum sealing drainage) was performed for transitional treatment. After the wounds were cleaned and the granulation were still fresh, the wounds were for debridement in the operating room. During the operation, 4 cases were fixed with the SternaLock^® plating system, and 1 case was only treated with debridement and suture in front of the sternum because it did not involve the sternum. Results Four cases were cured and discharged smoothly, and 1 case died due to multiple organ failure, but the wound healed well. Conclusion The VSD increased sternum blood flow, which accelerated the granulation tissue formation, further to prevent infection and stable sternum, create a good foundation for further debridement, meanwhile the SternaLock ^® plating system(consists of eight pass since the titanium plate and 2.4 mm drill lock screw) was used for fixation, which significantly increased the stability of the sternum, further improved the prognosis of patients.

Objective Influenza-associated necrotizing encephalopathy (IANE) in children is a serious complication of influenza. At present, there is a lack of indicators for early diagnosis and early warning. In this paper, the role of blood biochemical and cerebrospinal fluid detection in early warning of IANE in children is discussed, so as to provide a predictive reference for early diagnosis of IANE. Methods A retrospective analysis was conducted on children diagnosed with influenza and with neurological complications who were treated in our hospital from January 2016 to December 2020. Forty children with influenza-associated encephalopathy (IAE) and 32 children with IANE were included. Receiver operating characteristic curve (ROC) analysis was used to determine the predictive value of the selected variables. Results Compared with IAE group, the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine kinase (CK), lactate dehydrogenase (LDH), cerebrospinal fluid lactate dehydrogenase (CSF LDH) and cerebrospinal fluid protein (CSF PRO) were all increased in IANE group, and the differences between the two groups were statistically significant (P<0.05). The area under curve (AUC) of LDH, CSF LDH and CSF PRO used to distinguish IAE from IANE were 0.876, 0.853 and 0.831, respectively. The sensitivity and specificity of LDH>535 U/L for predicting IANE were 89.7% and 86.5% respectively. The sensitivity and specificity of CSF LDH>67 U/L for predicting IANE were 82.8% and 73.3% respectively. The sensitivity and specificity of CSF PRO＞0.49 g/L in predicting IANE were 73.7% and 76.6%. There were 10 deaths of IANE (43.3%) and 0 death of IAE (P<0.05). Conclusion The levels of LDH, CSF LDH and CSF PRO were significantly increased in IANE group, which could be used as early warning indicators for IANE. For such children, close evaluation, early prediction and intervention should be made to reduce sequelae and fatality rate and to improve prognosis.

Objective To detect the expression of SNCG in ovarian cancer tissue and its clinical significance, to clarify the relationship between the expression of SNCG in human ovarian cancer and the degree of malignancy, so as to provide theoretical basis for the diagnosis, treatment and prognosis of clinical ovarian cancer. Methods From January 2010 to January 2015 in First Affiliated Hospital of Medical College of Shihezi University,119 patients with ovarian cancer and 50 patients with normal ovarian which had complete clinical data and paraffin section were selected. Immunohistochemical method was used to detect ovarian SNCG expression, and the expression of SNCG relationship with clinical pathological characteristics and prognosis of patients with ovarian cancer was analyzed. Results The expression of SNCG in ovarian cancer tissue was significantly higher than that in normal ovarian tissue (χ²=73.575,P＜0.001). SNCG expression was correlated with tumor stage, degree of differentiation, lymph node metastasis, satisfying tumor reduction, CA125 and HE4 levels in ovarian cancer patients, and the differences were statistically significant (P＜0.05). It was not correlated with the tumor primary site, ascites, recurrence of ovarian tumor and chemotherapy resistance, and the differences were not statistically significant (P＞0.05).The overexpression of SNCG was correlated with PFS and OS in HGSOC patients, and the differences were statistically significant (P＜0.05). Analysis of multivariate Cox proportional risk model showed that SNCG was an independent prognostic factor in patients with HGSOC, related to PFS (HR=2.107,95%CI: 1.014-3.795,P=0.034) and OS (HR=1.238,95%CI: 0.716-1.928,P=0.047). Conclusion The high expression of SNCG in ovarian cancer is related to tumor stage, degree of differentiation, lymph node metastasis, satisfying tumor reduction, CA125 and HE4 expressions, but it is not related to the recurrence of ovarian cancer or chemotherapy resistance. The overexpression of SNCG protein can be used as an independent prognostic factor in patients with HGSOC for clinical diagnosis and treatment guidance.

P=0.097 3),但学生患者占比从2016年的2.52%上升到2020年的7.74%,上升了3.07倍。学生患者均为新发,男女性别比为1.27:1,以15～24岁年龄段的高中生和大学生构成为主,分别占45.55%和39.79%,两者合计85.34%。发现方式主要以转诊、追踪到位和因症到结防机构直接就诊为主,分别为44.50%、25.13%、23.56%,其中转诊比例最高,占了44.50％;各年的发现方式构成比差异未见统计学意义(χ²=12.057,P=0.441 1)。共登记涂阳患者45例,就诊延误10例,延误率22.22%,确诊延误2例,延误率4.44%;共登记涂阴患者146例,就诊延误29例,延误率19.86%,确诊延误3例,延误率2.05%。共登记培养阳性(涂阳培阳45例,涂阴培阳6例),对一线抗结核药物(HRZES)全敏感42例,全敏感率82.35%;单耐药9例,耐药率17.65%,其中单耐药率最高的为异烟肼和链霉素,不同年份的全敏感率未见统计学差异(χ²=3.81 P=0.432)。需开展筛查的学生肺结核患者178例,已开展筛查的患者169例,筛查率94.94%。需筛查的密切接触者7954例,实际接受筛查(开展了PPD或胸片筛查1项或以上)者7 898例,筛查率99.30%,发现活动性肺结核13例,检出率0.16%。密切接触者筛查方式:胸片筛查6 317人,发现胸片异常42人,异常率0.66%;PPD筛查7 897人,强阳性493人,强阳性率6.24%;症状筛查7 897人,自诉有症状64人,症状阳性率0.81%。结论 2016—2020年,广州市越秀区学生肺结核疫情较轻,患者以高中和大学生首次发病为主,男女差别不大,但就诊延误和确诊延误仍较普遍。其次,对学生患者及其密切接触者的筛查工作做得较好,及时发现了较多现症患者及近期感染者。因此,继续加强高中以上学校的结核病防治知识宣传工作和做好应筛必筛工作,是今后学校疫情控制的侧重点。
