Objective:To explore the influencing factors of false-positive serological reaction of syphilis.Methods:A total of 166 patients with false-positive serological reaction of syphilis (false-positive group), 145 patients diagnosed with early syphilis without treatment (positive control group) and 124 persons undergoing entry physical examination (negative control group) were included from January 2017 to February 2020 in Beijing Tongren Hospital, Capital Medical University. The gender, age and underlying diseases of the three groups were compared. Logistic regression was used to analyze the influencing factors of false-positive serological reaction of syphilis. The efficacies of chemiluminescence immunoassay (CLIA) and toluidine red unheated serum test (TRUST) were compared. Paired t test or chi-square test was used for statistical analysis. Results:In the false-positive group (166 cases), the age of 117 cases were more than 50 years old and 49 cases <50 years old. There were significant differences in age ((53.1±13.8) vs (24.7±2.8), t=22.56, P<0.01), autoimmune disease (36.7%(61/166) vs 6.5%(8/124), χ2=35.93, P<0.01), hepatitis (9.6%(16/166) vs 3.2%(4/124), χ2=4.92, P=0.026) and tumor (6.6%(11/166) vs 0.8%(1/124), χ2=4.68, P=0.030) between the false-positive group and the negative control group. There were significant differences in gender (there were 91(54.8%) males and 75(45.2%) females in the false-positive group, and 103(71.0%) males and 42(29.0%) females in the positive control group, χ2=8.67, P=0.003), age ((53.1±13.8) vs (34.4±12.9), t=20.13, P<0.01) and autoimmune disease (36.7%(61/166) vs 6.9%(10/145), χ2=39.14, P<0.01) between the false-positive group and the positive control group. Multivariate logistic regression analysis showed that gender (odds ratio ( OR)=2.692, 95% confidence interval ( CI) 1.504-4.816, P=0.001), age ≥50 years old ( OR=30.512, 95% CI 15.959-58.335, P<0.01), autoimmune disease ( OR=2.677, 95% CI 1.258-5.695, P=0.011) and hepatitis ( OR=4.408, 95% CI 1.799-10.799, P=0.001) were the influencing factors of false-positive serological reaction of syphilis. In the false-positive group, the positive rate of TRUST was 84.9% (141/166), which was higher than that of CLIA (23.5%(39/166)). The difference was statistically significant ( χ2=126.25, P<0.01). CLIA was 1.0-10.0 cut off index (COI) in 36 patients, and >10.0 COI in three patients.The difference was statistically significant ( χ2=52.51, P<0.01). The titers were ≤1∶4 in 139 patients and≥1∶8 in two patients with TRUST positive.The difference was statistically significant ( χ2=262.35, P<0.01). The sensitivity and specificity of CLIA were 95.2% and 96.0%, respectively, and those of TRUST were 77.2% and 91.1%, respectively. Conclusions:The influencing factors of false-positive serological reaction of syphilis include patients age ≥50 years and with autoimmune disease or hepatitis. The false-positive rate of TRUST is significantly higher than CLIA.

Objective To investigate the clinical features of primary retroperitoneal fibrosis (RPF), and to find out better method for diagnosis and therapy. Methods Nine patients with primary RPF in Peking Union Medical College Hospital since 1990 to 2003 were analyzed retrospectively. Results All patients had abnormal findings in CT or MRI, and 8 of them had chronic non-specific inflammation of the retroperitoneum in pathology. Six patients had renal involvement and 2 of them had severe renal failure. Eight of the patients had received therapy with corticosteroid or tamoxifene. Conclusions RPF is an uncommon collagen vascular disease characterized by a chronic non-specific inflammation of the retroperitoneum.Because of the atypical manifestations of RPF, awareness of the disease is important.CT and (or) open biopsy remains the gold standard for diagnosis.Management typically includes surgery and drug treatment.Corticosteroid therapy or more recently,tamoxifen has been used successfully. The clinical and radiographic improvement with drug treatment has been seen in several patients and confirmed the diagnosis,thereby early diagnosis and treatment can bring the patient more excellent renal and general outcome.

Objective To investigate whether the release of fibroblast growth factor-1 ( FGF-1 ) was changed after inhibition of S100A13 gene (small hairpin RNA, shRNA)and serum-deprivation in human thyroid cancer cells (TT cells ). Methods The S100A13-shRNA pENTRTM/U6 entry vector was transfected into TT cells. The expression of S100A13 mRNA and protein was detected by immunoflurescence, real-time RT-PCR, and Western blot. Then TT cells were treated with S100A13 gene inhibition and serum-deprivation. The changes in release of FGF-1 were detected by indirect immunoflurescence, RT-PCR, and ELISA. Results S100A13 shRNA transfected TT cells (S100A13 RNAi cells)had a reduction of S100A13 gene and protein expression by 80%.Indirect immunofluorescence indicated FGF-1 was mostly localized in the cytoplasm and nucleus of TT cells in primary culture. When serum-deprivation stress was given to TT cells, FGF-1 in cytoplasm almost disappeared in the cells at 6 h. RT-PCR indicated that when serum-deprivation stress was given to TT cells the mRNA of FGF-1 was reduced. ELISA showed that with inhibition of S100A13, the release of FGF-1 was reduced (P＜0.05).Conclusion S100A13-shRNA pENTRTM/U6 entry vector transfected TT cells may inhibit the expression of S100A13 and reduce the release of FGF-1.

OBJECTIVEChinese herbal medicine has been extensively used in the treatment of vascular dementia (VaD), but lacked systematic review on its efficacy and safety. So we conducted a systematic review to assess the efficacy and safety of Chinese herbal medicine in treating VaD.

METHODSCNKI, CBM, PubMed, and Wiley Online Library were retrieved for randomized trials (RCTs) on Chinese herbal medicine treating VaD patients. Randomized parallel control trials by taking Chinese herbal medicine as one treatment method and placebos/cholinesterase inhibitors/Memantine hydrochloride as the control were included. Quality rating and data extraction were performed. RevMan5.2.0 Software was used for meta-analysis. Standardized mean difference (SMD) at 95% confidence interval (CI) was used to indicate effect indicators of results.

RESULTSSeven RCTs met the inclusive criteria. Totally 677 VaD patients were randomly assigned to the treatment group and the control group. Descriptive analyses were performed in inclusive trials. The cognitive function was assessed in all trials. Results showed Mini-Mental state examination (MMSE) score was better in the Chinese herbal medicine group than in the placebo group, but with no significant difference when compared with the donepezil group (P > 0.05). Adverse reactions were mainly manifested as gastrointestinal symptoms such as abdominal pain in the Chinese herbal medicine group. But they occurred more in the donepezil group than in the Chinese herbal medicine group.

CONCLUSIONSThe methodological quality of included trials was poor with less samples. Results of different trials were lack of consistency. Present evidence is not sufficient to prove or disapprove the role of Chinese herbal medicine in improving clinical symptoms and outcome indicators of VaD patients. Their clinical efficacy and safety need to be supported by more higher quality RCTs.

Objective:To evaluate the effect of remote ischemic conditioning (RIC) on left ventricular (LV) myocardial perfusion, myocardial viability, LV remodeling, regional and global LV function serially following acute myocardial infarction (AMI) in Chinese mini-pigs.Methods:AMI was established in 12 Chinese mini-pigs (8 males, 4 females; age: 6-8 months) and they were randomly divided into RIC group ( n=6) and non-RIC group ( n=6). RIC was performed in pigs by blood pressure inflation on the lower limbs for 5 min period and 4 cycles immediately after surgery. A series of myocardial perfusion imaging and gated 18F-fluorodeoxyglucose (FDG) myocardial metabolism PET/CT imaging were performed longitudinally at the 1st, 14th, 28th and 56th days after AMI, and parameters including total perfusion defect (TPD), hibernating myocardium (HM), Scar, left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), summed motion score (SMS), summed thickening score (STS) and changes of these parameters were obtained. Independent-samples t test and Mann-Whitney U test were used to analyze data. Results:Nine Chinese mini-pigs survived after surgery and were performed imaging. Compared to non-RIC group ( n=4), HM at the 28th ((6.0±2.4)% vs (17.0±4.6)%; t=-4.158), TPD 14th-1st ((-11.8±5.4)% vs 9.0%(4.5%, 15.0%); z=2.449), TPD 28th-1st ((-15.3±3.9)% vs (12.0±3.0)%; t=-10.071), TPD 56th-1st ((-18.0±6.5)% vs 9.0%(4.5%, 12.0%); z=2.449), HM 28th-1st ((-10.5±6.9)% vs (8.3±2.1)%; t=-4.507), HM 56th-1st (-15.0%(-17.5%, -8.5%) vs 2.0%(0%, 7.0%); z=2.449) and LVEDV 14th-1st (-0.5(-2.5, 0) ml vs (13.0±4.4) ml; z=2.470) were reduced in RIC group ( n=5; all P<0.05). Conclusion:RIC can improve myocardial perfusion, delay LV remodeling in the acute stage and salvage hibernating myocardium in the subacute stage and chronic stage.

Patent ductus arteriosus (PDA) is a common problem encountered in the early neonatal period, particularly in preterm infants. Optimal management of PDA in preterm infants remains controversial. Despite considerable historical and physiological data indicating a persistent PDA may be harmful, robust evidence of long-term benefits or harms from treatment is lacking. This has been equated to a lack of benefit but is also a reflection of the fact that many clinical trials were designed to assess the effects of short-term (2-8 days) rather than prolonged exposure to a PDA. No clinical trials have been designed to assess the effects of prolonged exposure of persistent PDA on morbidity and mortality of very premature infants. Significant changes in management of PDA, i.e., less treatment for PDA, have evolved in recent years. This paper reviews the current literature and evidence for treatment options and research progress of PDA in infants with gestational age of <28 weeks.

In this study, 120 patients with rheumatic heart disease undergoing valve replacement were randomly divided into the control group and the Qishen group, with 60 cases in each group. Before the operation, the control group was given routine heart and diuretic treatments and placebo of Qishen Yiqi dropping pills for seven days (0.5 g each time, three times a day); While the Qishen group was given Qishen Yiqi dropping pills for seven days (0.5 g each time after meal, three times a day) on the basis of the routine treatments. The right ventricular end-diastolic volume (RVEDV), end-systolic volume (RVESV), stroke volume (SV) and right ventricular ejection fraction (RVEF) were detected after the operation. The results showed that patients in the two groups showed significantly lower right ventricular end diastolic volume (RVEDV), right ventricular end systolic volume (RVESV) and stroke volume (SV) decreased than that before the operation, but with significantly higher Ejection fraction (RVEF) significantly than that before the operation. However, the Qishen group showed a significantly lower right heart function reduction than the control group, with the statistical significance in the differences (P < 0.05). This indicated that the pretreatment with Qishenyiqi Drop Pills showed a remarkable efficacy in the improvement of right ventricular function after valve replacement.

Objective:To investigate the characteristics of health-related risky behaviors in adolescents with bipolar disorder.Methods:Fifty adolescents aged 12 -18 years,fulfilled the International Statistical Classification of Diseases and Related Health Problems,Tenth Revision(ICD-10)criteria for bipolar disorder(29 in depressive state, 19 in manic state,and 2 in mixed state)and 100 healthy-matched controls were recruited.Their health-related risky behaviors were assessed using the Questionnaire for Adolescents Health-related Risky Behavior Inventory (AHRBI) and the Questionnaire for Adolescents Health-related Risky Behavior Inventory for Parent (AHRBI-P).Results:The bipolar group had higher AHRBI scores in the total scale and six subscales than controls,including Aggression and Violence (AV),Health-Compromising Behavior (HCB),Rule Breaking (RB),Unprotected Sex (US),Self-injury and Suicide (SS),and Smoking and Drinking(SD)[Total scores,55.5(38,119)vs.46(38,65);P <0.05].Besides, the scores of 26 items of bipolar group were all higher than controls(Ps <0.05).The scores in the total scale and six subscales had no difference between AHRBI and AHRBI-P.According to the partial correlation analysis (de-pressive state =0;manic state =1),the AHRBI and AHRBI-P scores of Self-injury and Suicide subscale were nega-tively associated with the episode state (r =-0.32,-0.33;Ps <0.05).The AHRBI scores of'destroy properties'which belongs to the Aggression and Violence subscale were positively associated with the episode state (r =0.32, P <0.05).Conclusion:The adolescents with bipolar disorder have more health-related risky behaviors than the healthy adolescents.The depressive patients have higher risk of suicide.While,the risky behavior of destroying properties tend to occur among the manic patients.

Objective To observe the effect of adenosine A1 receptor (A1AR) on the megalin defect in type 1 diabetic mice with early kidney disease.Methods 7-8 week-old,baseline body weight and fasting blood glucose matched wild type (WT) C57BL/6J mice were selected,and randomly divided into two groups:control group (n=6) and WT DM group (n=6).In the same way,male A1AR knock-out C57BL/6J mice were selected as A1AR-/-DM group (n=6).DM model was established by intraperitoneal injection of streptozocin.The blood glucose (BG),body weight (BW),kidney weight (KW),24 h proteinuria (24hUP) and albumin creatine ratio (ACR) were measured at 4 weeks.The renal pathological lesion was observed and the expression of megalin in proximal tubules was examined by immunohistochemistry.The expression of caspase-1,IL-18 and A1AR were detected by Western blotting.Results At 4th week,compared with WT control mice,the BG,BW,KW and 24hUP of WT DM mice were increased significantly (n=6,P ＜ 0.01),with the pathological glomerular enlargement,mesangial cell proliferation,extracellular matrix accumulation and renal tubule hypertrophy being observed.Immunohistochemistry revealed decreased expression of megalin,an important multiligand protein receptor on the brush border of proximal tubular epithelial cells in WT DM mice,which was correlated with 24hUP (r=-0.645,P ＜ 0.01).Compared with the control mice,the expressions of caspase-1,IL-18 and A1AR were significantly increased in WT DM mice (P ＜ 0.05).For A1AR-/-DM mice,more serious pathological lesion and megalin defect,together with increasing of casapase-1 and heavier proteinuria were observed than those in WT DM mice.Conclusion A1AR may play a protective role in megalin expression of diabetic mice with early kidney disease,in which the mechanism may be associated with caspase-1 related pyroptosis pathway.The details need further exploration.
