ABSTRACT
Objective:To analyze common respiratory pathogens epidemiology in hospitalized children with lower respiratory tract infection (LRTI) in a single center in Shanghai, and to provide the basic data support for clinical diagnosis and treatment of children with LRTI in Shanghai.Methods:Children with LRTI in Children′s Hospital of Fudan University were enrolled from January 1, 2015 to December 31, 2019, and respiratory samples were collected and tested by direct immunofluorescence assay and real time polymerase chain reaction. The epidemiological characteristics of different respiratory pathogens were analyzed. Chi-square test was used for statistical analysis.Results:A total of 18 716 children were included, the total detection rate of respiratory pathogens was 36.96% (6 918/18 716), and the most frequent detected pathogen was Mycoplasma pneumoniae (MP) (15.31%(2 866/18 716)), followed by respiratory syncytial virus (RSV) (10.40%(1 946/18 716)) and parainfluenza virus Ⅲ (PIV-Ⅲ) (4.65%(871/18 716)). The detection rate of pathogens in female was significantly higher than that in male (38.48%(2 936/7 630) vs 35.92%(3 982/11 086), χ2=12.72, P<0.001). RSV and influenza virus A (Flu-A) infections peaked in winter. The detection rates of influenza virus B (Flu-B) and human metapneumovirus (MPV) were higher in winter and spring. PIV-Ⅲ infection peaked in spring and summer. The peak of PIV-Ⅱ infection occurred in summer and autumn. The infections of adenovirus (ADV), MP, Chlamydia trachomatis (CT) and PIV-Ⅰ were prevalent throughout the year without significant seasonality. The detection rate of RSV declined with age, while the detection rate of MP increased with age. The co-infection rate was 1.65%(309/18 716), and the predominant co-infection type was MP and RSV (0.37%(70/18 716)). Conclusions:A variety of pathogens lead to children′s LRTI in Shanghai from 2015 to 2019, with the common infection of MP, RSV and PIV-Ⅲ. Different pathogens showed different epidemiological characteristics in age and season distributions.
ABSTRACT
Objective:To investigate the epidemiological characteristics of classic human astrovirus (HAstV) among children under five years old with acute diarrhea, and to understand the role of HAstV in children acute diarrhea.Methods:A total of 1 010 fecal specimens were collected in 1 010 outpatients under five years old with acute diarrhea admitted to Children′s Hospital of Fudan University, Shanghai from January 2012 to December 2016. Reverse transcription polymerase chain reaction (PCR) or PCR was used for screening classic HAstV, group A rotavirus, norovirus and adenovirus. Genotypes of classic HAstV were determined by nucleotide sequencing and phylogenetic tree analysis.Results:The overall positive rate of classic HAstV was 2.7%(27/1 010). The detection rates of classic HAstV from 2012 to 2016 were 6.9%(10/144), 3.5%(5/144), 2.1%(3/144), 1.5%(4/265) and 1.6%(5/313), respectively. Almost 96.3%(26/27) of children infected with HAstV were 0 to 36 months of age. The prevalence of classic HAstV infections displayed a typical autumn/winter seasonality except in 2016. All the positive classic HAstV strains were genotyped as HAstV-1 with two lineages of HAstV-1a and HAstV-1b. Among them, the lineage of HAstV-1a was the predominant subtype (63.0%, 17/27). There were 77.8%(21/27) of the children with acute diarrhea only infected with classic HAstV, whereas for the remaining cases a variety of other enteric viruses were detected (three cases co-infected with HAstV and group A rotavirus, two cases co-infected with HAstV and adenovirus, and one case co-infected with HAstV, group A rotavirus and adenovirus).Conclusions:Children infected with HAstV are mainly less than 36 months of age. Although the genotype of classic HAstV detected in this study is single, but the lineages are in a state of dynamic change. Long-time and continuous monitor for the epidemiology of classic HAstV is needed to avoid outbreak of diarrhea in children.
ABSTRACT
Background@#Postherpetic neuralgia (PHN) is the most common complication of acute herpes zoster. The treatment of PHN remains a challenge for clinical pain management. Despite the effectiveness of anticonvulsants, antidepressants, and lidocaine patches in reducing PHN, many patients still face intractable pain disorders.In this randomized controlled study, we evaluated whether hydromorphone through intravenous patient-controlled analgesia (IV PCA) was effective in relieving PHN. @*Methods@#Patients with PHN were randomly divided into two groups, one group received oral pregabalin with IV normal saline, another group received oral pregabalin with additional IV PCA hydromorphone for two weeks. Efficacy was evaluated at 1, 4, and 12 weeks after the end of the treatments. @*Results@#Two hundred and one patients were followed up for 12 weeks. After treatment, numerical rating scale (NRS) score of patients in the hydromorphone group was significantly lower than that of the control group, and the difference of NRS scores between the two groups was statistically significant at 4 and 12 weeks after treatment. The frequency of breakthrough pain in the hydromorphone group was significantly lower than that in the control group 1 and 4 weeks after treatment.After treatment, the quality of sleep in the hydromorphone group was significantly improved compared with the control group. The most common adverse reactions in the hydromorphone group were dizziness and nausea, with no significant respiratory depression. @*Conclusions@#IV PCA hydromorphone combined with oral pregabalin provides superior pain relief in patients with PHN, which is worthy of clinical application and promotion.

ABSTRACT
Objective Based oncomputer-aided design (CAD) technology, we compared the optimized method of locating inserting point (2 cm lateral to and 1 cm below angulus oris) with traditional ones and assessed its clinical value by simulating foramen ovale (FO) cannulation. Methods Skull CT data of 100 primary trigeminal neuralgia patients were used in this study and three-dimensional reconstruction with FO cannulation simulation were conducted. With self-control test method, each patient was divided into three groups: group of optimized insertion point (method O) : point 2 cm lateral to and 1 cm below angulus oris as the insertion point; group of traditional entry point A (method A) : 2.5 cm lateral the angulus oris as the insertion point; group of traditional entry point B (method B) : intersecting the external extension of angulus oris and the vertical line of the lateral eye angle as the entry point. Puncture simulation was performed along connecting line of insertion point and the central point of the FO. We recorded results of simulation and measured the available area and short diameter of FO in the direction of puncture. Results The cases that the puncture route was obstructed of methods O, A and B were 15, 28 and 31, respectively. The occlusion rate of method O was significantly lower than those of methods A and B (P ＜ 0.01 or P ＜ 0.05). The available area of methods O, A and of B were (9.45 ± 6.57) mm2, (6.91 ± 5.96) mm2, (6.59 ± 5.86) mm2, respectively. The available area of method O was significantly larger than those of methods A and B (P ＜ 0.01 or P ＜ 0.05). The short diameters of methods O, A and B were (2.25 ± 1.04) mm, (1.81 ± 0.97) mm, (1.71 ± 0.92) mm, respectivtly. Short diameters of method O was significantly longer than those of methods A and B (P ＜ 0.01 or P ＜ 0.05). Conclusion compared with the traditional positioning method, the optimized method can provide better condition for puncture through Hartel approach.
ABSTRACT
Objective To explore the effectiveness and precision of 3D printing navigational template in puncturing of foramen rotundum for radiofrequency thermocoagulation to treat primary trigeminal neuralgia (V2).Methods Forty-three patients (27 males,16 females,aged 45-85 years,ASA grade Ⅰ or Ⅱ) with primary trigeminal neuralgia (V2) were included and randomly divided into experimental group (group A,n=21) and control group (group B,n=22).After taking a CT scan and 3D reconstruction of each patient's skull,puncture simulations were carried out,then the final puncture schemes were decided.In group A,puncture was performed under guidance of navigational template but was conducted empirically in group B.In both groups,3D-CT image and electrical stimulation were used in all the procedures to confirm the location of point of needle before radiofrequency thermocoagulation.The cases of successful puncture in one-time,times of CT scanning,radiant quantity,operation time during the operation in both groups were recorded.Furthermore,NRS scores and complications including hypoesthesia,motor function degeneration,hematoma,absence of corneal reflex,cerebrospinal fluid leakage were recorded after procedure.Results The rate of successful puncture in one-time of group A was superior than that of group B (90.4% vs.22.7%).Compared with group B,CT scan times [(1.1±0.3) times vs.(2.8±1.3) times],radiant quantity [(323.1±108.7) mGy*cm vs.(787.8±355.7) mGy*cm],operation time [(15.3±5.5) min vs.(28.5±6.5) min] in group A were significantly reduced (P<0.05).NRS scores of both two groups were obviously reduced after surgery [group A: (3.1±1.7) scores vs.(8.5±0.7) scores;group B: (3.1±1.5)scores vs.(8.5±0.7) scores] (P<0.05),but the effectiveness in group A was not superior than group B.No serious complications occurred in all patients.Conclusion On the basis of sufficient preoperative planning of puncture approach,3D printing template can significantly enhance the effectiveness and precision of puncture of foramen rotundum,improving the efficiency and quality of radiofrequency treatment of primary trigeminal neuralgia (V2).
ABSTRACT
Objective To compare the molecular epidemic characteristics of human astrovirus (HAstV) between outpatient and hospitalized children with acute diarrhea,and to investigate the relationship between HAstY infection and diarrhea in children.Methods A total of 298 cases were randomly collected from hospitalized children from January 2008 to December 2010 in Children's Hospital of Fudan University,and 360 specimens were collected from outpatients with acute diarrhea from August 2010 to July 2011.Reverse transcriptase polymerase chain reaction (RT-PCR) was used to detect rotavirus (RV),human calicivirus (HuCV),HAstV and human adenovirus (HAdV).H AstV genotype was determined by gene sequencing and phylogenetic analysis.Results Epidemiology of HAstV in hospitalized children was as follows:among the included 298 samples,HAstV was detected in 27.2％ (81/298) of the patients,compared with 33.9％ (42/124),33.8％ (25/74) and 14.0％ (14/100),respectively from 2008 to 2010.HAstV diarrhea occurred throughout the year and peaked in January,March,and April.95.1％ (77/81) of the infected children were 0-35 months old.All the episodes of HAstV were mixed with other diarrhea virus infection.Molecular epidemiology of HAstV in outpatient children with diarrhea was as follows:the overall incidence of HAstV was 1.9 ％ among the 360 cases (7/360).The seasonal distribution of HAstV's gastroenteritis showed a peak in November.All the outpatient children were 0-35 months old.Three cases were single infection with HAstV and the others were coinfection with RV (3 cases) or HAdV (1 case).All of the detected HAstV,either in inpatients or outpatients,belonged to HAstV-1.Conclusions The detection rate of HAstV in hospitalized children is significantly higher than that in outpatients.Most HAstV infections in hospitalized children are ascribed to nosocomial infections.Most episodes of HAstV infection were accompanied with other diarrhea viruses infection.HAstY single infection is seen in outpatient children while the detection rate is very low,implying that HAstV co-infection with other viruses plays a main role in diarrhea in most instances.
ABSTRACT
Objective To investigate the factors influencing the lipid control success rate among patients with coronary heart disease (CHD).Methods Questionnaire and clinical data reviews were conducted to investigate the general information,disease characteristics and patients controlling blood lipid and by blood biochemical tests were done to detect the lipid levels.The relationships between lipid control success rate and general information,disease characteristics and patients' behaviors were analyzed by chi-square test and logistic regression analysis.Results The blood lipid success rate was only 67.09％ in patients with CHD combined dyslipidemia.The education level,cardiovascular disease risk grading,complications,body mass index,medication compliance and dietary evaluation were the main factors influencing the patients' success in blood lipid control.Conclusion The lipid control success rate can be raised by taking measurements to help patients with CHD and dyslipidemia control weight and increase medication compliance and dietary behavior.
ABSTRACT
Objective: To study the effect of PI3K-Akt signaling pathway on the openness degree of mitochondrial permeability transition pore (mPTP)in the aged model rats of myocardial ischemic preconditioning (IPC),and to clarify its possible mechanism.Methods:Thirty-five Wistar Wistar rats (aged 21-23 months)were randomly divided into ischemia reperfusion (I/R)group,I/R+Wort (Wortmannin,inhibitor of PI3K)group,IPC group and IPC+ Wort group (n=7).The models of I/R and IPC were established and 0.6 mg·kg-1 Wort were injected to the caudal veins of the rats in Wort group before reperfusion. After 120 min reperfusion, the myocardium tissue protein was extracted, and the Akt and p-Akt protein expression levels were detected by Western blotting method.The myocardial mitochondrial of rats was separated through differential centrifugation, and the superoxide level, SOD level and openness degrees of mPTP were determined by microplate reader. Results:Compared with I/R group (0.288±0.071),the expression level of p-Akt protein in myocardium tissue of the rats in IPC group (0.346±0.051)was increased (P 0.05).Compared with I/R group (1.15±0.15),the SOD activity in mitochondrial of the rats in IPC group (1.39±0.14)was increased (P 0.05).Compared with I/R group,the mPTP openness degree in IPC group was decreased (P 0.05).Compared with IPC group,the mPTP openness degree in IPC+ Wort group was increased (P < 0.05).Conclusion:The IPC of aged rats can inhibit the openness of mitochondrial permeability transition pore through activating the PI3K-Akt signaling pathway.
ABSTRACT
Objective To analyze implementation outcomes of the new health reform policy at a provincial hospital for the past six months.Methods Trend analysis,factor analysis and ratio analysis approaches were used in monthly surveillance,along with comparative study of the data before and after the reform,to probe into impacts of the new policy on hospital operations.Results Medical income increased by 22.09％,mainly contributed by volume growth (22.28％) of medical services; Medical income dropped by 0.16％ due to pricing policy factors; medicine proportion deceased by 4.84％; following the reform,the income per outpatient and inpatient increased by 12.32％ and 5.35％ respectively.Conclusion Following the drug zero profit policy and rise of the charging standards for medical treatment service at the hospital,the growth of total income mainly comes from growing volume of medical services instead of pricing policy factors.The new health reform is conducive to optimizing the hospital's income structure and raising value to doctors' technical service.
ABSTRACT
<p><b>OBJECTIVE</b>To study the etiology, pathogenesis, clinicopathologic characteristics, prognosis and treatment of congenital pulmonary airway malformation (CPAM).</p><p><b>METHODS</b>Eighteen cases of CPAM were enrolled into the study. The clinical history, autopsy findings and immunohistochemical results were evaluated, with review of literature. The pathogenetic mechanism, pathologic features and differential diagnosis of CPAM were studied.</p><p><b>RESULTS</b>Histologic examination showed that 2 cases were classified as Stocker type I, 12 cases as type II, and 4 cases as type III. The lesion was unilateral and involved single lobe in 13 cases. The remaining 5 cases had bilateral diseases. Of the 18 cases studied, 12 cases showed single organ involvement and 6 cases had malformations affecting multiple organs. The associated malformations included cardiac anomalies (4 cases), polycystic kidney with gastrointestinal atresia (1 case) and nuchal cystic hygroma with hydrothorax (1 case).</p><p><b>CONCLUSIONS</b>CPAM is a rare pulmonary disorder. The etiology of this non-neoplastic condition is unknown. Imaging analysis is a valuable tool to suggest CPAM, while definite diagnosis requires pathologic examination. The overall prognosis is determined by the presence of associated malformations, fetal hydrops and pulmonary hypoplasia.</p>

<p><b>OBJECTIVE</b>To study the expression and clinicopathologic significance of cancer stem cell markers CD44v6 and CD24 in ovarian serous carcinoma tissues.</p><p><b>METHODS</b>One hundred and two cases of ovarian carcinoma diagnosed during the period from June, 2001 to December, 2010 were retrieved from archival files. The histology slides were reviewed and a two-tier system for grading of ovarian serous carcinoma was applied. The expression of CD44v6 and CD24 was detected by immunohistochemistry using EnVision method. The relationship between CD44v6/CD24 expression and various clinicopathologic parameters was analyzed.</p><p><b>RESULTS</b>There were 46.1% (47/102) and 59.8% (61/102) cases expressing CD44v6 and CD24, respectively. Both CD44v6 and CD24 expression showed positive correlation with higher histopathologic grade (P = 0.003 and P < 0.05, respectively). CD24 expression also correlated with the presence of lymph node metastasis (P < 0.05). There was no statistically significant relationship between the expression of these two markers (χ(2) = 0.394, P = 0.530). The age of the patients, histopathologic grade, clinical stage and nodal status correlated with progression-free survival time (P < 0.05). CD44v6 expression and histopathologic grade correlated with the overall survival time (P < 0.05). Patient age was an independent poor prognostic factor by multivariate analysis.</p><p><b>CONCLUSIONS</b>CD44v6 expression, age older than 50 years, high clinical stage and presence of lymph node metastasis are associated with poor prognosis in patients with ovarian serous carcinoma. The two-tier system for grading of ovarian serous carcinoma is useful in predicting survival; and high tumor grade represents an important poor prognostic indicator for ovarian serous carcinoma.</p>

Objectives To investigate gestational multiple metabolic abnormalities aggregation and diagnostic criteria for gestational metabolic syndrome(GMS),and to analyze the risk factors of GMS.Methods A cohort study recruiting 309 pregnant women with preeclampsia,627 pregnant women with gestational diabetes mellitus(GDM)and 1245 normal pregnant women was performed from January 2008 to December 2011 in Guangdong Women and Children's Hospital.Information regarding age,gestational weeks,basic blood pressure,admission blood pressure,height and body mass index(BMI)before pregnancy was recorded.Biochemical indicators including fasting plasma glucose(FPG),fasting insulin (FINS),total cholesterol(TC),triglyceride(TG),high density lipoprotein(HDL-C),low density lipoprotein(LDL-C),free fatty acids(FFA)were tested.GMS was diagnosed with three or all of the following conditions:(1)overweight and/or obesity before pregnancy(BMI ≥ 25 kg/m2);(2)hypertension with blood pressure ≥ 140/90 mm Hg(1 mm Hg =0.133 kPa);(3)hyperglycemia:diagnosed as GDM;(4)dyslipidemia with TG≥3.23 mmol/L The incidence of GMS of the three groups were calculated and the risk factors were analyzed.Results(1)The age,gestational weeks,basic blood pressure,admission blood pressure,BMI before pregnancy of women with preeclampsia and women with GDM were significantly different compared to normal women,respectively(P ＜ 0.01).(2)Biochemical indicators of women with preeclampsia were as following:FPG(4.6 ± 1.0)mmol/L,FINS(10.1 ± 5.6)mU/L,TC(6.3 ±1.6)mmol/L,TG(3.9 ± 1.8)mmol/L,HDL-C(1.4 ±0.4)mmol/L,LDL-C(3.0 ± 1.0)mmol/L,FFA (0.8 ±0.4)mmol/L.And those in women with GDM were:FPG(4.7 ± 0.9)mmoL/L,FINS(10.2 ± 5.8)mU/L,TC(5.7 ± 1.3)mmol/L,TG(3.2 ± 1.1)mmol/L,HDL-C(1.4 ± 0.4)mmol/L,LDL-C (2.7 ± 0.9)mmol/L,FFA(0.6 ± 0.3)mmol/L In normal pregnant women they were:FPG(4.3 ±0.5)mmol/L,FINS(9.0±4.4)mU/L,TC(5.7 ±1.1)mmol/L,TG(2.8 ±1.1)mmol/L,HDL-C (1.5 ± 0.4)mmol/L,LDL-C(2.9 ± 0.8)mmol/L,FFA(0.6 ± 0.2)mmol/L Statistic differences were found in preeclampsia and GDM women compared to normal women respectively(P ＜ 0.01).(3)The prevalence of GMS in preeclampsia group and in GDM group was 26.2％(81/309)and 13.6％(85/627),statistically different from that of the control group(0)(P ＜0.01).(4)Compared to normal women,women with preeclampsia had higher risk of developing GMS(OR =1.62,95 ％ CI 1.31-2.00,P ＜ 0.01).The risk factors were BMI(OR =1.29,95％ CI 1.13-1.47)and TG(OR =2.49,95％ CI 1.87-3.31).Also,women with GDM had higher risk of developing GMS than normal women(OR =1.27,95％ CI 1.09-1.49,P ＜ 0.01),and the risk factors were BMI(OR =1.13,95 ％ CI 1.04-1.23)and TG(OR =1.16,95 ％ CI 1.02-1.33).TG was the independent risk factor in both preeclampsia women and GDM women(P ＜ 0.01,P ＜ 0.05).HDL-C seemed to have less importance in identifying GMS(P ＞ 0.05).Conclusions According to the GMS diagnostic criteria used in this study,some preeclampsia patients and some GDM women had aggregation of multiple metabolic abnormalities including pre-pregnancy overweight/obesity,hyperglycemia,high blood pressure and dyslipidemia.TG was the independent risk factor for GMS.HDL-C seemed to have less importance in identifying GMS.
ABSTRACT
Objective To investigate the dynamic characteristic of molecular epidemiology of group A Rotavirus (RV) by analyzing viral genotypes,disease seasonality,and the patients' age distribution,so that to provide theoretical basis for preyention and control of RV diarrhea in children.MethodsA total of 380 RV antigen positive samples were selected from 5176 stool specimens collected from ＜5 year-old patients with acute diarrhea who were admitted to Children's Hospital of Fudan University during January 2006 to December 2008. Multiplex nested reverse transcription polymerase chain reaction (RT-PCR) was used to analyze the RV genotypes.ResultsDuring 2006-2008,the incidence of RV related diarrhea peaked from October to December and about 96.8％ of all RV episodes occurred in patients younger than 3 years old,The predominant genotype was G3 which accounted for 58.4％ (222/380),G9 was an emerging genotype with the prevalence rate as high as 10.8％ (41/380).G1 and G2 types were rarely found during the three years.Infections with both G3 and G9 were the major mixed genotype G infection. Genotype P [8] was predominant with the prevalence rates of 64.6％ (53/82) and 46.8％ (58/124) in 2006 and 2008,respectively,whereasgenotype P[4] was predominant in 2007 (38,5％,67/174).P[6] and P[9] were found as minor types.The major mixed genotype P infection were genotype P[4] and P[8]. The proportion of undetermined genotype G and genotype P strains tended to increasing during 2006-2008.Genotype P [8]G3 was the major RV strain (20.5％) in Shanghai during 2006-2008 and the other prevalent genotypes included P[4]G3 and P[m]G3.Conclusion The infection of group A RV in Shanghai presents some new molecular epidemiology characteristics during 2006-2008,such as switch of predominant genotypes and diversification of prevalent genotypes.
ABSTRACT
The powder X-ray diffraction Fourier fingerprint pattern technique was used to develop a new quantitation method for the analysis of andrographolide and dehydroandrographolide. And the high performance liquid chromatography method was used to evaluate the quantity of andrographolide and dehydroandrographolide. The relationship of diffraction peak intensity and content of andrographolide and dehydroandrographolide was investigated. The powder X-ray diffraction Fourier fingerprint pattern analysis technique can be used to evaluate the quantity of andrographolide and dehydroandrographolide in the herb simultaneously.
