ObjectiveTo evaluate the effectiveness and safety of Qiaoqi Formula （翘芪组方） for mild influenza. MethodsA randomized controlled study was designed， recruiting 74 patients with mild influenza， who were randomly divided into trial group and control group. The trial group took Qiaoqi Formula orally， 40ml each time， twice a day； the control group took Lianhua Qingwen Capsules （连花清瘟胶囊） orally， 1.4 g each time， three times a day. Both groups were treated for 3 consecutive days and follow-up for 4 consecutive days after treatment. The time for fever reduction including onset of fever reduction， complete fever reduction time， fever reduction rates at 24， 48 and 72 hours， improvement of influenza symptoms， total traditional Chinese medicine （TCM） symptom score， and safety indicators in two groups after treatment were recorded. ResultsSixty-five patients were ultimately included， including 36 in the trial group and 29 in the control group. Onset time of fever reduction in the trial group was （15.49±23.47） h， the complete fever reduction time （21.37±30.06）h， and the 24 h， 48 h， 72 h， fever reduction rate was 77.14%， 88.57%， 91.42% respectively. The above indicators of the control group showed as （17.58±20.38）h， （24.30±21.87）h， 61.29%， 90.32%， 96.77% respectively， with no statistically significant differences （P＞0.05）. On the 7th day after treatment， the total score of TCM syndromes in trial group and control group decreased compared to those before treatment （P＜0.05）. There was no statistically significant difference in the cure rate， significant effective rate， effective rate， and total effective rate of TCM syndromes between groups （P＞0.05）. On the 4th day， the lymphocyte ratio of patients in the control group was higher than before treatment， while alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， urea， and creatinine of both groups before and after treatment were within the normal range. The main adverse reactions in both groups were mild headache and dizziness， and no serious adverse reactions observed. ConclusionThe therapeutic effect of Qiaoqi Formula in treating mild influenza is equivalent to Lianhua Qingwen Capsules， which can shorten the fever reduction time， improve clinical symptoms， and no adverse events observed during the study.

Analysis of genomic copy number variations in two sisters with primary amenorrhea and hyperandrogenism / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To analyze genomic copy number variations (CNVs) in two sisters with primary amenorrhea and hyperandrogenism.</p><p><b>METHODS</b>G-banding was performed for karyotype analysis. The whole genome of the two sisters were scanned and analyzed by array-based comparative genomic hybridization (array-CGH). The results were confirmed with real-time quantitative PCR (RT-qPCR).</p><p><b>RESULTS</b>No abnormality was found by conventional G-banded chromosome analysis. Array-CGH has identified 11 identical CNVs from the sisters which, however, overlapped with CNVs reported by the Database of Genomic Variants (http://projects.tcag.ca/variation/). Therefore, they are likely to be benign. In addition, a -8.44 Mb 9p11.1-p13.1 duplication (38,561,587-47,002,387 bp, hg18) and a -80.9 kb 4q13.2 deletion (70,183,990-70,264,889 bp, hg18) were also detected in the elder and younger sister, respectively. The relationship between such CNVs and primary amenorrhea and hyperandrogenism was however uncertain. RT-qPCR results were in accordance with array-CGH.</p><p><b>CONCLUSION</b>Two CNVs were detected in two sisters by array-CGH, for which further studies are needed to clarify their correlation with primary amenorrhea and hyperandrogenism.</p>

Risk factors and prognostic analysis of cranial nerve impairment in 121 patients with tuberculous meningitis / 中华传染病杂志

Objective To investigate the risk factors associated with cranial nerve impairment in patients with tuberculous meningitis.Methods A total of 121 patients with tuberculous meningitis who were admitted to Huashan Hospital from 2000 to 2011 were reviewed retrospectively.Demographic data (gender,age),course of disease,initial results of cerebral spinal fluid (CSF) tests,occurrence of cranial nerve impairment and prognosis of these patients were collected.All the patients were followed up for at least 3 months,and for those with cranial nerve impairment,the minimum follow-up period was 1 year in order to judge the recovery of cranial nerve impairment.Multivariate analysis was performed to study the associated risk factors.Results Out of 121 patients,22 (18.2 ％)developed cranial nerve impairment.Nerves involved were abducens nerve,oculomotor nerve,optic nerve and auditory nerve,and impairment of single nerve occurred in 9 (40.9 ％),8 (36.4 ％),7(31.8％) and 1(4.5％) patient,respectively.Three cases had more than one group of cranial nerves involved,accounting for 13.6％ of the 22 patients with cranial nerve impairment.The incidence of conscious disturbance was significantly higher in patients with cranial nerve impairment than those without impairment (77 ％ vs 45 ％,P=0.020).Delay in diagnosis (OR =1.017,95 ％ CI:1.001-1.033,P=0.040) and occurrence of conscious disturbance (OR =3.242,95 ％ CI:1.142-9.205,P=0.027) were independent predictive factors of cranial nerve injury.During one-year follow-up,90.9％ of patients were fully recovered from cranial nerve impairment,with a median duration of 1 month (range 0.5-6.0 months).Conclusions Cranial nerve impairment is a common complication in patients with tuberculous meningitis.Delay in diagnosis and occurrence of conscious disturbance were independent predictive factors.Most cranial nerve impairment were reversible,and timely diagnosis and treatment are important ways to reduce complications.

Cranial nerve impairment in cryptococcal meningitis: predictors and prognosis / 中华传染病杂志

Objective To understand the predictors and prognostic significance of cranial nerve impairment in non-acquired immune deficiency syndrome (AIDS) patients with cryptococcal meningitis.Methods A total of 145 non-AIDS patients with cryptococcal meningitis admitted to Huashan Hospital,Fudan University from Jan 2000 to Dec 2010 were reviewed retrospectively.Clinical characteristics,initial antifungal therapies and outcome of these patients were analyzed.Continuous variables were analyzed using t test and categorical variables were compared by x2 test or Fisher's exact test.Multivariate analysis was performed by binary Logistic regressions.Results Out of 145 patients,52 (35.9％) patients had cranial nerve impairment at enrollment.Optic (25/52,48.1％) and oculomotor (22/52,42.3％) nerves were the most commonly involved,followed by auditory (12/52,23.1％),abducens (6/52,11.5％),olfactory (4/52,7.7％) and facial (3/52,5.8％) nerves.The best predictive factor of cranial nerve injury was duration of diagnosis (OR =1.056,95％ CI:1.002-1.111).The risk of cranial injury would increase by 5.6％ with one-week delay of diagnosis.Intracranial hypertension and low cerebrospinal fluid cell count were also the independent predictive factors (both P＜0.05).In the follow-up period,73.3％ patients who had cranial nerve injuries were fully recovered,with a median time of 3 (0.5-24.0) months.The independent predictors of recovery were numbers of nerve involved (OR =0.230,95 ％ CI:0.066-0.800,P=0.021) and amphotericin B (AmB) plus 5-fluorocytosine,triazole antifungal agent therapy (OR=10.317,95％CI:2.086-51.025,P=0.004).Conclusions Cranial nerve impairment occurs in one-third of non-AIDS patients with cryptococcal meningitis.Delay in diagnosis,intracranial hypertension and low cerebrospinal fluid cell count are independent predictive factors.Less cranial nerve involvement and AmB plus triazole therapy predict recovery.

Objective To assess the value of S index and FIB-4 for diagnosis of liver fibrosis in patients with chronic hepatitis B (CHB) by comparing with traditional indexes APRI and Forns.Methods A total of 361 patients with confirmed CHB from the First Hospital of Nanjing Medical University and Huashan Hospital Affiliated to Fudan University during January 2006 and December 2011 were enrolled in the study.The clinical,laboratory and pathological data of patients were collected.Four noninvasive score systems APRI,Forns,S index and FIB-4 were computed.With liver biopsy as the gold standard,the area under the ROC curve (AUROC) was used to assess the value of above 4 score systems in diagnosis of liver fibrosis,and Z test was performed to evaluate the effectiveness of above systems.Results The areas under ROC curve (AUCs) of APRI,Forns,S index and FIB-4 for significant fibrosis (≥S2) were (0.737 ±0.027),(0.716 ± 0.028),(0.745 ± 0.026) and (0.781 ± 0.025),respectively.When the cut off value of FIB-4 was set at 1.62,the sensitivity,specificity,positive predictive value (PPV) and negative predictive value (NPV) for diagnosis of significant fibrosis were 59.3％,85.8％,89.4％ and 51.2％,respectively,which were better than Forn index (Z =3.28,P =0.001).While for S4 (cirrhosis) the AUCs of APRI,Foms,S index and FIB-4 were (0.687 ± 0.035),(0.792 ± 0.028),(0.863 ± 0.024) and (0.832 ± 0.025),respectively.When the cut off value of S index was set at 1.06,the sensitivity,specificity,PPV and NPV for diagnosis of cirrhosis were 77.9％,85.5％,59.4％ and 93.5％,respectively,which were better than APRI and Forns (Z =6.74 and 3.21,P ＜ 0.01).Conclusions APRI,Forns,S index and FIB-4 are simple and accurate methods for assessing liver fibrosis.FIB-4 and S index are better than APRI and Forns in diagnosis of significant fibrosis and cirrhosis,which may replace liver biopsy in certain extend.

Application of iTRAQ multiple labeling and tandem mass spectrometry in proteomic research of human peripheral blood mononuclear cells / 生物医学工程学杂志

This paper is aimed to establish and optimize proteomic research platform using isobaric tags for relative and absolute quantitation (iTRAQ) so as to facilitate further proteomic research of human peripheral blood mononuclear cells (hPBMC). We collected hPBMC, after protein extraction and trypsin digestion, we labeled the samples with iTRAQ reagents and then subjected to mass spectrometry. In triplicates, thirty precursors were randomly selected and detected; as a result, 26, 28 and 29 peptides were respectively tagged with ITRAQ reporter ions. The labeling efficiencies ranged between 86.7%-96.7%, with no significant difference among the groups (P>0.05). The coefficient of variance for the relative ratios of peptides from different proteins was ranged from 7.6% to 25.5% and there were no significant differences across the groups (P>0.05). The coefficient of variance for the relative ratios of different peptides from the same protein was varied from 9.3% to 19.1% and the differences across groups were not significant (P>0.05). The labeling of iTRAQ combined with tandem mass spectrometry in PBMC was successful with favourable reproducibility and accuracy, which could lay a foundation for further proteomic study of hPBMC in autoimmune disorders.

Detection and analysis of genomic copy number variations in a 46,X0, +der(?) fetus by array-based comparative genomic hybridization / 基础医学与临床

Objective To understand genomic copy number variations (CNVs) and ascertain karyotype for a 46,X0, + der(?) fetus, and investigate possibility and superiority of array-based comparative genomic hybridization (array-CGH ) in clinical cytogenetic diagnosis. Methods G-banded chromosome analysis was carried out. The whole genome of the fetus was scanned and analysed by array-CGH. The results of array-CGH were confirmed by RT-qPCR. Results G-banded chromosome analysis showed that the fetal karyotype was 46,X0, +der(?). Array-CGH revealed the derivative chromosome as Y chromosome without CNVs. A total number of 118 submicroscopic CNVs were identified. Comparable results between array-CGH and RT-qPCR were obtained for 9 novel CNVs. Conclusion Comparing with conventional cytogenetic analysis, array-CGH is of high resolution, high-throughput and high accuracy, which provides a technical platform for accurate detection of submicroscopic chromosomal aberrations.

Prenatal diagnosis and molecular cytogenetic analysis of a de novo isodicentric chromosome 18

Isodicentric chromosome 18 [idic[18]] is rare structural aberration. We report on a prenatal case described by conventional and molecular cytogenetic analyses. The sonography at 24 weeks of gestation revealed multiple fetal anomalies; radial aplasia and ventricular septal defect were significant features. Routine karyotyping showed a derivative chromosome replacing one normal chromosome 18. the parental karyotypes were normal, indicating that the derivative chromosome was de novo. Array comparative genomic hybridization [array-CGH] revealed 18p11.21[right wards arrow] qter]. Fluorescent in situ hybridization [FISH] confirmed that the derivative chromosome was idic[18]. Our report describes a rare isodicentric chromosome 18 and demonstrates that array-CGH is a useful complementary tool to cytogenetic analysis for reliable identifying derivative chromosome
