Objective To analyze the clinical features and factors affecting prognosis for intracerebral hemorrhage (ICH) during pregnancy and postpartum.Methods A study of ICH was performed on 61 women in Beijing Tiantan Hospital,Capital Medical University between January 1997 and December 2014,and all cases were diagnosed with cerebral hemorrhage or subarachnoid hemorrhage during pregnancy or six weeks after delivery with CT or MRI after exclusion of ICH due to craniocerebral trauma.The subjects were divided into surgery (n=26) and conservative treatment (n=35) groups according to different ways of treatment;pregnancy associated problems (n=11) and cerebrovascular diseases groups according to the aetiology of ICH;low (n=13) and high score group (n=48) according their Glasgow score at the first visit;and short clinical onset to diagnosis time (O-D time) group (≤ 24 h,n=33) and long O-D time (＞24 h) group (n=28).We compared the maternal clinical features and prognosis between different groups with t,Mann-Whitney U or Chi-square tests.A stratified logistic regression was used to assess the effect of factors affecting the prognosis.Results The average gestational age at the onset of ICH of the 61 cases was (28.8±8.3) weeks (6-40 weeks),the Glasgow score was (11.3±4.8),the median O-D time was 24.0 h,the modified Rankin scale (mRS) was 2.7,and 14 maternal deaths were reported (23.0％).Among the 61 women,three were terminated in early trimester,12 terminated in second trimester,and the rest 46 delivered in late term among which two fetal deaths,44 live births,and four neonatal deaths.Thus the perinatal infant death rate was 13.0％ (6/46).The difference of maternal clinical features and prognosis between the surgery and conservative treatment group was not significant (all P＞0.05).However,comparison between the cerebrovascular disease and pregnancy associated diseases group showed the latter had a lower Glasgow score and Apgar score [12.2(3.0) vs 7.5(12.0),(8.9±1.9) vs (7.2±2.6)],the higher mRS [2.4(2.0) vs 3.9(5.0)] and gestational age [(27.7±8.4) vs (34.9±4.1)],maternal mortality rate [14.0％ (7/50) vs 7/11] and perinatal death rate [5.4％ (2/37) vs 4/11] (t or x2=-3.09,-2.34,1.93,1.17,2.12 and 1.78,all P＜0.05).For women with low Glasgow score,the median O-D time was shorter than that of higer Glasgow score group (8.0 vs 48.0 h),the mRs and maternal mortality rate were higher 4.9(2.5) vs 3.1(2.0);9/13 vs 10.4％(5/48),t,U or x2=426.00,5.77 and 19.14,all P＜0.05].The short O-D time group showed lower Glasgow score and average Apgar score of the newborns than the long O-D time group [9.8(11.3) vs 13.2(2.0),(7.9±2.7) vs (9.2±0.9);t,U or x2=-2.91 and-2.23,both P＜0.05].The Glasgow scores was negatively associated with the mRs (OR=-0.26,95％CI:-0.16 to-0.05).In particular,O-D time (OR=0.03,95％CI:0.00-0.66) and pre-eclampsia (OR=0.33,95％CI:0.12-0.26) were both positively related to maternal mRs.However,the Glasgow scores,surgical treatment,O-D time and concomitant pre-eclampsia were irrelevant to the death ofperinatal infants (all P＞0.05).Conclusions The prognosis is poor in women with ICH during pregnancy or postnatal period whose Glasgow score was low or O-D time was long,or the ICH occurred due to pre-eclampsia.Antenatal care should be strengthened and early identification and diagnosis might improve the prognosis.

It remains controversial whether tumor necrosis factor (TNF)-α antagonism is effective for asthma. This meta-analysis was performed to evaluate efficacy of TNF-α antagonism in treatment of patients with asthma. MEDLINE, EMBASE, LILACS, and CINAHL databases were searched for English-language studies published through January 3, 2010. Randomized-controlled trials comparing TNF-α antagonism with control therapy were selected. For each report, data were extracted in relation to the outcomes analyzed: asthma exacerbation, asthma quality of life questionnaire scores, and forced expiratory volume in 1 second. Four assessable trials were identified including 641 patients with asthma. TNF-α antagonism therapy was superior to control therapy in preventing exacerbations in asthmatics [pooled odds ratio 0.52 (95% confidence interval 0.29-0.88), P=0.02]; however, there was a nonsignificant reduction in asthma quality of life questionnaire scores [0.23 (0 to 0.47), P=0.05], forced expiratory volume in 1 second [0.03, (-0.14 to 0.10), P=0.74] when analyzed using standardized mean differences. TNF-α antagonism was superior to control chemotherapy in terms of asthma exacerbation, but not asthma quality of life questionnaire scores or forced expiratory volume in 1 second.

Objective:To investigate the effect of rapamycin (Rapa) on apoptosis of acute myeloid leukemia THP-1 cells induced by idarubicin (IDA) and its molecular mechanism.Methods:The THP-1 cells were treated with 10, 20, 40 and 80 nmol/L Rapa for 1 h, and the cells without Rapa treatment were set up. Western blot was used to detect the conversion of autophagy marker LC3 protein in THP-1 cells (the ratio of LC3Ⅱ/LC3Ⅰ), flow cytometry was used to detect the apoptotic rate, and the pretreatment concentration of Rapa was determined. THP-1 cells were treated with different concentrations of IDA for 24 h, the cell proliferation inhibition rate of IDA for THP-1 cells was detected by CCK-8 method, and the half maximal inhibitory concentration ( IC50) was calculated. THP-1 cells with or without Rapa treatment were treated by IDA with the concentration of lower than IC50 for 24 h, CCK-8 method was used to detect cell proliferation inhibition rate, flow cytometry was used to detect cell apoptosis, real-time fluorescent quantitative polymerase chain reaction was used to detect the expression changes of autophagy-related genes Beclin-1, LC3 and p62, and Western blot was used to detect the conversion of autophagy marker LC3 protein. Results:The ratio of LC3Ⅱ/LC3Ⅰ in THP-1 cells treated by 20 nmol/L Rapa was higher than that in the untreated cells ( P=0.002 4). The apoptotic rate in THP-1 cells treated by 80 nmol/L Rapa was higher than that in the untreated cells ( P=0.007 3). According to the results of Western blot and flow cytometry, 20 nmol/L Rapa was selected as the pretreatment concentration. The IC50 of IDA for THP-1 cells treated with IDA for 24 h was 59.874 nmol/L. After treated with 50 nmol/L IDA for 24 h, the proliferation inhibitory [(69.67±5.03)% vs. (41.67±3.51)%] and apoptotic rates [(74.35±4.83)% vs. (41.25±5.24)%] in THP-1 cells pretreated by Rapa were higher than those in the unpretreated cells (both P<0.05); the Beclin-1 and LC3 mRNA expression levels and the ratio of LC3Ⅱ/LC3Ⅰ in THP-1 cells pretreated by Rapa were higher than those in the unpretreated cells, and the expression of p62 mRNA was lower than that in the unpretreated cells (all P<0.05). Conclusion:Rapa can enhance the apoptosis of THP-1 cells induced by a relative low dose of IDA, which may be achieved through inducing excessive autophagy in THP-1 cells.

To compare and evaluate the discriminatory ability and potential value of pulsed field gel electrophoresis (PF-GE) and multiple locus VNTRs analysis (MLVA) on the genotyping of Brucella ,a total of 60 strains of Brucella and three standards (16M ,544A ,1330S) were genotyped simultaneously by PFGE and MLVA .The result indicated that the similarity coefficient among the 63 isolates was from 72 .1-100 .0% by PFGE ,and could distinguish three species of B .melitensis ,B .su-is and B .abortus at the similarity level of 94 .4% .There were 14 clusters and 29 PFGE types identified by PFGE with discrim-inatory index (DI) of 0 .957 5 at the similarity level of 100% ;the similarity coefficient among the 63 isolates was from 16 .9-100 .0% by MLVA ,and could distinguish three species of Brucella at the similarity level of 52 .3% .There were 8 clusters and 47 MLVA types identified by MLVA with discriminatory index (DI) of 0 .985 2 at the similarity level of 100% .It's suggested that PFGE and MLVA could be used to distinguish three species of Brucella in the similarity coefficient of certain ,but could not effectively distinguish the type in the same species .Both of these two methods could be used for Brucella molecular typing , but MLVA is better than PFGE for its relatively higher discriminating ability .

Objective To investigate the role of circulating neutrophil extracellular trap (NET) levels in the postoperative formation of deep vein thrombosis (DVT) in patients undergoing total knee arthroplasty (TKA). Methods Circulating NET levels were measured preoperatively and on postoperative days 1, 3, and 7 in 30 patients diagnosed with DVT by venography after TKA and 30 controls from May 2014 to July 2015. Results In patients with DVT, the mean circulating NET levels were significantly higher on postoperative days 1 and 3 compared with those in the non?DVT group (postoperative day 1, 1.598 ± 0.067 vs. 1.212 ± 0.037, t=7.514, P=0.000;postoperative day 3, 1.305±0.044 vs. 1.167±0.032, t=2.675, P=0.015). ROC curve analysis revealed the inferior sensitivity and specificity of NET levels on postoperative day 3 compared with postoperative day 1. Area under the curve (AUC) postoperative day 1 was 0.828 (95%CI:0.722, 0.933, P=0.000);AUC postoperative day 3 was 0.677 (95%CI:0.541, 0.814, P=0.018). The cutoff point for NET levels on postoperative day 1 was 1.294, with a sensitivity of 80%, a specificity of 80%, a posi?tive predictive value of 80%, and a negative predictive value of 80%. After Logistic regression, the NET level on postoperative day 1 was considered an independent predictor of DVT (OR:24.08, 95%CI:4.94, 117.28, P=0.000). Conclusion High circulating NET levels are associated with DVT in patients who undergo TKA. NETs may serve as a potential biological marker to delineate patients undergoing TKA who are most at risk for DVT.

Objective To explore the ultrasonography findings and pathological features of adrenal ganglioneuroma and to improve diagnostic level. Methods Ultrasonography appearance and clinical pathological data of 12 cases of primary adrenal ganglioneuroma were retrospectively analyzed. The location, shape, size, echo characteristics, with or without calcification, the color signal of blood flow and its neighboring structure relationship on ultrasound were analyzed. Re-sults In 12 cases, 9 cases were found in the right adrenal gland and 3 cases in the left. All the tumors were solitary and the diameter was between 1.8 and 12 cm. The tumors were round or oval, some irregular or"embedded" growth. E-chogenic focus were found in 5 cases which was pathologically confirmed calcification, 3 cases of tumor showed a small dot color flow signal, all tumors with clear boundaries around the surrounding tissue. Pathology of tumor was mainly composed of ganglion cells and Schwann cells. Conclusion Ultrasonography is of great value in the diagnosis of adrenal ganglioneuroma owing to some specific sonograms.

The primary importance of magnetic resonance (MR) imaging in evaluating anal fistulas lies in its ability to demonstrate hidden areas of sepsis and secondary extensions in patients with fistula in ano. MR imaging is relatively expensive, so there are many healthcare systems worldwide where access to MR imaging remains restricted. Until recently, computed tomography (CT) has played a limited role in imaging fistula in ano, largely owing to its poor resolution of soft tissue. In this article, the different imaging features of the CT and MRI are compared to demonstrate the relative accuracy of CT fistulography for the preoperative assessment of fistula in ano. CT fistulography and MR imaging have their own advantages for preoperative evaluation of perianal fistula, and can be applied to complement one another when necessary.

Objective To assess the myocardial blood flow and reserve function by rest and stress 13 N-NH3 PET myocardial perfusion imaging ( MPI) , and evaluate the diagnostic value of PET and risk fac-tors of non-obstructive coronary microvascular disease ( CMVD) type 1. Methods A total of 56 patients (28 males, 28 females;age:(52.0±7.6) years) with clinical suspected CMVD type 1 from April 2017 to December 2018 were prospectively enrolled. The coronary CT angiography, coronary angiography and other clinical data were recorded. All patients underwent one-day rest and stress 13 N-NH3 PET MPI. Images were analyzed and the absolute myocardial blood flow ( MBF) and coronary flow reserve ( CFR) were obtained. Patients were divided into CMVD type 1 ( CMVD) group and non-CMVD group. The differences between 2 groups were analyzed by two-sample t test and logistic regression. Results Among 56 patients, 20 patients were diagnosed as CMVD type 1, and 36 patients were excluded as non-CMVD group. The proportion of smoking and diabetes in the CMVD group was significantly higher than that in the non-CMVD group (χ2 val-ues:9.433 and 4.114, both P<0.05). The stress MBF ((2.37±0.61) vs (3.83±1.25) ml·min-1·g-1;t=-4.807, P<0.001) and CFR (2.67±0.60 vs 3.81±0.96;t=-4.751, P<0.001) were lower in smokers than those in non-smokers, and the stress MBF was lower in diabetes patients than that in non-diabetes patients ((2.63±0.98) vs (3.62±1.28) ml·min-1·g-1;t=-2.758, P=0.008). Smoking might be the risk factor for lower stress MBF (odd ratio (OR)=0.310, 95％ CI:0.114-0.880) and lower CFR (OR=0.278, 95％ CI:0. 080-0.894), and diabetes might be the risk factor for lower stress MBF (OR=0.254, 95％ CI:0.073-0. 887) . Conclusions PET MPI can be used for the diagnosis of CMVD type 1. Smoking and diabetes are likely to be associated with the onset of CMVD type 1.

Objective To investigate the predictive value of urinary exosomal microRNA(miR)-29 c in the clinical outcome of organ-and non-organ-confined bladder urothelial carcinoma(BUC).Methods From January 2017 to March 2022,152 patients with BUC were recruited from the Department of Urology in our hospital as a validation set.In addition,126 non-cancer controls were selected from the physical examination center of our hospital.The expression level of urinary exosomal miR-29c was detected by real-time quantitative PCR.Results In the validation set,urinary exosomal miR-29c level in BUC patients was significantly lower than that in non-cancer control group(P＜0.05),while urinary exosomal miR-17-5p level and miR-590-5p level were not significantly different(P＞0.05).The area under ROC curve of urinary exosomal miR-29c for the diagnosis of BUC was 0.969(95％CI:0.953～0.986),and the corresponding sensitivity and specificity were 92.1％and 90.2％,respectively.In subtype analysis,urinary exosomal miR-29c levels were further reduced in patients with non-organ-confined BUC compared with patients with organ-confined BUC(P=0.009).Overall survival(OS),disease-free survival(DFS)and disease-specific survival(DSS)were longer in the urinary exosomal miR-29c high expression group(P＜0.05).Conclusion Low levels of urinary exosomal miR-29c are an adverse prognostic factor for survival in patients with BUC,and are promising as a predictor of adverse clinical outcomes of organ-and non-organ-confined BUC.

Objective: To compare the effectiveness and clinical safety between the two through the observation of Orthokeratology lens and multifocal soft lens. Methods: By using prospective longitudinal design, sixty patients (120 eyes) with orthokeratology lens and multifocal soft lens were selected. After 1, 3, 6 and 12 months, our tests were conducted, including ocular surface disease index (OSDI) questionnaire, tear break up time(BUT), corneal fluerescein staining (CSF) and meibomian gland function assessment, before and after wearing glasses, ocular axis and refraction in 6,12 and 18 months after were evaluated to assess the effect of myopia control. Results: But in the orthokeratology lens group was lower than the soft lens group after two months. The difference was statistically significant( t=4.35, P <0.05). After 1 month of wearing glasses, BUT in the orthokeratologylens group was shorter than before( F=305.83, P <0.05). In the group of soft lens, there was no statistically significance before and after wearing glasses( F= 0.38, P >0.05). There was no difference in corneal fluorescence staining (CSF) and meibomian gland function between the two groups before and after wearing glasses.( F time=1.55, 1.38, 10.15, 1.50, P >0.05, F group=2.31, 0.02， P >0.05). After 18 months of wearing orthokeratology lens, the average degree of spherical lens increased by -0.53 D, which was different from that before wearing( F=6.54, P <0.05). After wearing soft lens 18 month, the average degree of spherical lens increase by -0.34 D, which was different from that before wearing( F=2.88, P <0.05). After 18 months of wearing glasses, there were differences in the growth of ocular axis between the two groups( F =2.73, 2.83, P <0.05). Conclusion Orthokeratology lens and multifocal soft lens are both safe and effective measures to control myopia.
