Objective To discuss the reasons of false judgments of localization of the rupture aneurysms and find the way to fix this problem in patients with multiple intracranial aneurysms. Methods The clinical data of 25 consecutive patients, who presented with their first spontaneous subarachnoid hemorrhage and had multiple intracranial aneurysms from 2003 to 2009 in our hospital, were analyzed retrospectively. The rupture aneurysms were determined according to Nehls' method that reported before, and the supposed responsible rupture aneurysms w0ere clipped within 48 hours after hemorrhage in all patients. More aneurysms that could not be accessed in the same surgical session were surgically terated later. Results The location of the rupture aneurysm was verified at the time of surgery in all 25 patients. The concordance rate of the prediction and the reality of the rupture aneurysm was 80% (20/25). Four patients ( 16% ) ,in whom the ruptured aneurysm was not correctly identified,rebled after surgery,and 2 patients died as a result of the rebleeding One patients had no clear diagnosis at the end. Conclusion In the reported cases, about 80% rupture aneurysms could be correctly diagnosed before treatment according to the CT and DSA examinations. If clear diagnosis couldn't be made,additional examinations should be considered, such as CTA or MRI. Rupture aneurysms must be confirmed during the operation and the other aneurysms should be checked to exclude additional responsible aneurysms in all cases.

Objective To evaluate the effect of computer-aided design of composite materials with epoxide acrylate maleic (E) and hydroxyapatite (H) in cranioplasty. Methods A total of 45 patients with cranium defects were treated with cranioplasty by using skull bone flaps made of composite materials including epoxide acrylate maleic (E) and hydroxyapatite (H) ,which was designed with computer aid according to individual requirements. The patients were followed up for 6-36 months. Results After cranioplasty with composite EH, there occurred subcutaneous fluid in one patient and mild bone collapse in one. The composite EH showed good histocompatibility, with no infection or rejection. Conclusion During cranioplasty, use of computer-aided design of composite EH takes advantages of good accuracy, short operation time, good biocompatibility and good clinical efficiency.

Spontaneous bacterial peritonitis (SBP) is a common serious complication of end-stage liver disease. Intestinal microecology is closely associated with the development, progression, and prognosis of SBP, and bacterial translocation is the key pathogenesis of SBP. This article summarizes the intestinal microecology in patients with liver cirrhosis and briefly describes the mechanism of action of intestinal flora in the development and progression of SBP, thus providing a theoretical basis for the clinical regulation of intestinal microecology and treatment of SBP.

Objective To investigate the serum levels of brain derived neurotrophic factor (BDNF) and heat shock protein 70 (HSP70),and evaluate their clinical significance in brain injury of children with complicated febrile convulsions (CFC).Methods Forty-three patients with CFC,41 children with simple febrile convulsions and 36 healthy controls were recruited in this study; their serum levels of BDNF and HSP70 were detected by enzyme linked immunosorbent assay (ELISA); correlation between levels of BDNF and HSP70 and both time of twitch duration and twitch frequency were analyzed.Results The mean serum concentrations of BDNF (4.96±1.21 ng/mL) and HSP70 (2.86± 0.93 ng/mL) in patients of CFC group were significantly higher than those in patients of simple febrile convulsions and healthy controls (P＜0.05); while no significant difference was noted between patients of simple febrile convulsions and healthy controls (P＞0.05).These changes were closely related to the duration time and frequency of convulsions(r=0.553,P=0.015; r=0.587,P=0.012; r=0.526,P=0.024; r=0.562,P=0.018).Conclusions It is sure that some brain injury exists in children with CFC; BDNF and HSP-70 might be one of the molecular mechanisms for the brain injury and protective effect.

Objective:To analyze the effects of angiotensin converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB) on coronavirus disease 2019 (COVID-19) patients with hypertension, and to provide an evidence for selecting antihypertensive drugs in those patients.Methods:Clinical data were retrospectively analyzed in 58 COVID-19 patients with hypertension admitted to Shanghai Public Health Clinical Center from January 20 to February 22, 2020, including epidemiological history, clinical manifestations, laboratory findings, chest CT and outcome. Patients were divided into ACEI/ARB group and non-ACEI/ARB group.Results:Twenty-six patients were in ACEI/ARB group and the other 32 patients in non-ACEI/ARB group, with median age 64.0 (49.5, 72.0) years and 64.0 (57.0, 68.8) years respectively. The median time to onset was 5(3, 8) days in ACEI/ARB group and 4 (3, 7) days in non-ACEI/ARB group, the proportion of patients with severe or critical illness was 19.2% and 15.6% respectively. The main clinical symptoms in two groups were fever (80.8% vs. 84.4%) and cough (23.1% vs. 31.3%). The following parameters were comparable including lymphocyte counts, C-reactive protein, lactate dehydrogenase, D-dimer, bilateral involvement in chest CT (76.9% vs. 71.9%), worsening of COVID-19 (15.4% vs. 9.4%), favorable outcome (92.3% vs. 96.9%) between ACEI/ARB group and non-ACEI/ARB group respectively (all P>0.05). However, compared with non-ACEI/ARB group, serum creatinine [80.49 (68.72, 95.30) μmol/L vs. 71.29 (50.98, 76.98) μmol/L, P=0.007] was higher significantly in ACEI/ARB group. Conclusions:ACEI/ARB drugs have no significant effects on baseline clinical parameters (serum creatine and myoglobin excluded) , outcome, and prognosis of COVID-19 patients with hypertension. Antihypertensive drugs are not suggested to adjust in those patients, but the potential impairment of renal function as elevation of serum creatinine should be paid attention in patients administrating ACEI/ARB drugs.

ObjectiveTo investigate the clinical features of acute hepatitis E (AHE) patients with or without severe jaundice and the risk factors for severe jaundice. MethodsA retrospective analysis was performed for the clinical data of 179 AHE patients who were admitted to Shanghai Public Health Clinical Center Affiliated to Fudan University from January 1, 2018 to March 26, 2020. According to whether total bilirubin (TBil) was ＞171 μmol/L, the patients were divided into AHE-mild jaundice (AHE-M) group and AHE-severe jaundice (AHE-S) group, and the two groups were compared in terms of clinical data and laboratory markers. The t test or the Mann-Whitney U test or the chi-squared test was used for comparison, and a binary logistic regression analysis was used to identify independent risk factors. ResultsOf all 179 patients, 101 (56.42%) were found to have severe jaundice. Compared with the AHE-M group, the AHE-S group had a significantly higher proportion of male patients (80.20% vs 61.54%, χ2=7.612, P=0.006), a significantly longer length of hospital stay ［29 (19-45) days vs 18 (14-22) days, Z=-6.035, P＜0.001］, a significantly higher number of patients with liver failure (23 vs 0, χ2=18.373, P＜0.001), and a significantly poorer prognosis (P＜0.001). Compared with the AHE-M group, the AHE-S group had significantly higher baseline anti-HEV-IgM, alpha-fetoprotein, and liver elasticity (Z=-3.534, -3.588, and -4.496, all P＜0.001), significantly lower baseline CD4 (Z=-2.015, P＜0.05), significantly higher peak values of TBil, direct bilirubin, creatinine, prothrombin time, international normalized ratio, and absolute neutrophil count (Z=-11.016, -10.926, -2.726, -4.787, -4.989, and -6.016, all P＜0.01), a significantly lower peak value of gamma-glutamyl transpeptidase (GGT) (Z=-4.55, P＜0001), and significantly lower valley values of albumin, prealbumin (PA), and absolute lymphocyte count (Z=-4.685, -5.087, and -4.818, all P＜0.001). The logistic regression analysis showed that anti-HEV-IgM (odds ratio ［OR］=1.022, 95% confidence interval ［CI］: 1005-1.039, P=0.012), GGT (OR=0.995, 95%CI: 0.993-0.998, P=0.001), PA (OR=0.991, 95%CI: 0.983-0.999, P=0.02), and neutrophils (OR=1.486, 95%CI: 1.169-1.889, P=0.001) were independent risk factors for severe jaundice in AHE patients. ConclusionThere is a relatively high proportion of male patients among the AHE patients with severe jaundice, with a long length of hospital stay, a large number of patients with liver failure, and poor prognosis. Anti-HEV-IgM, GGT, PA, and neutrophils are independent risk factors for severe jaundice in AHE patients.

Compared to conventional cancer treatment, combination therapy based on well-designed nanoscale platforms may offer an opportunity to eliminate tumors and reduce recurrence and metastasis. In this study, we prepared multifunctional microspheres loading I-labeled hollow copper sulfide nanoparticles and paclitaxel (I-HCuSNPs-MS-PTX) for imaging and therapeutics of W256/B breast tumors in rats. F-fluordeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) imaging detected that the expansion of the tumor volume was delayed (<0.05) following intra-tumoral (i.t.) injection with I-HCuSNPs-MS-PTX plus near-infrared (NIR) irradiation. The immunohistochemical analysis further confirmed the anti-tumor effect. The single photon emission computed tomography (SPECT)/photoacoustic imaging mediated by I-HCuSNPs-MS-PTX demonstrated that microspheres were mainly distributed in the tumors with a relatively low distribution in other organs. Our results revealed that I-HCuSNPs-MS-PTX offered combined photothermal, chemo- and radio-therapies, eliminating tumors at a relatively low dose, as well as allowing SPECT/CT and photoacoustic imaging monitoring of distribution of the injected agents non-invasively. The copper sulfide-loaded microspheres, I-HCuSNPs-MS-PTX, can serve as a versatile theranostic agent in an orthotopic breast cancer model.

Objective To analyze the clinical features of patients with coronavirus disease 2019 (COVID-19) in Shanghai and to investigate the risk factors for disease progression to severe cases. Methods The clinical data of 292 adult patients with COVID-19 hospitalized in Shanghai Public Health Clinical Center from January 20, 2020 to February 10, 2020 were retrospectively analyzed, including 21 severe patients and 271 mild patients. The demographic characteristics, epidemiological history, history of underlying diseases and laboratory examinations were compared between the two groups. Measurement data were compared using t test or Mann-Whitney U test. The count data were compared using hi-square test. The binary logistic regression equation was used to analyze the risk factors for the progression of patients to severe cases. Results Among the 292 patients, 21 were severe cases with the rate of 7.2% (21/292). One patient died, and the mortality rate was 4.8% in severe patients. The severe patients aged (65.0±15.7) years old, 19 (90.5%) were male, 11 (52.4%) had underlying diseases, 7 (33.3%) had close relatives diagnosed with COVID-19. The mild patients aged (48.7±15.7) years old, 135 (49.8%) were male, 74 (27.3%) had underlying diseases, 36 (13.3%) had close relatives diagnosed with COVID-19. The differences between two groups were all significant statistically ( t =-4.730, χ 2 =12.930, 5.938 and 4.744, respectively, all P <0.05). Compared with the mild patients, the levels of absolute numbers of neutrophils, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, creatinine, serum cystatin C, C reactive protein (CRP), procalcitonin , D -dimer, pro-B-type natriuretic peptide (proBNP), serum myoglobin, creatine kinase (CK), creatine kinase isoenzyme (CK-MB), serum troponin I (cTnI) in severe patients were all significantly higher ( U =2 091.5, 1 928.0, 1 215.5, 729.0, 1 580.5, 1 375.5, 917.5, 789.5, 1 209.0, 1 434.0, 638.0, 964.5, 1 258.0 and 1 747.5, respectively, all P <0.05), while the levels of lymphocyte count, albumin, transferrin, CD3 + T lymphocyte count, CD8 + T lymphocyte count and CD4 + T lymphocyte count in severe patients were all significantly lower ( U =1 263.5, t =4.716, U =1 214.0, 962.0, 1 167.5 and 988.0, respectively, all P <0.05). Further logistic regression analysis showed that the albumin (odds ratio ( OR )=0.806, 95% CI 0.675-0.961), CRP ( OR =1.016, 95% CI 1.000-1.032), serum myoglobin ( OR =1.010, 95% CI 1.004-1.016), CD3 + T lymphocyte count ( OR =0.996, 95% CI 0.991-1.000) and CD8 + T lymphocyte count ( OR =1.006, 95% CI 1.001-1.010) at admission were independent risk factors for the progression of COVID-19 patients to severe illness (all P <0.05). Conclusions Severe cases of patients with COVID-19 in Shanghai are predominantly elderly men with underlying diseases. Albumin, CRP, serum myoglobin, CD3 + T lymphocyte count and CD8 + T lymphocyte count could be used as early warning indicators for severe cases, which deserve more clinical attention.
