OBJECTIVETo evaluate the effects of Huafenqinutang combined with vardenafil for the treatment of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) with erectile dysfunction.

METHODSOne hundred and thirty-eight cases diagnosed as CP/CPPS with erectile dysfunction were randomized into trial group (70 cases) and control group (68 cases) for treatment with Huafenqinutang for 8 weeks, and in the former group, vardenaffil was added since the fifth weeks. All the cases were evaluated according to NIH-CPSI and IIEF-5 scores at 4 weeks and 8 weeks, respectively.

RESULTSAt the end of the fourth weeks, NIH-CPSI score was 13.1-/+4.7 in the trial group and 13.3-/+4.5 in the control group, which were comparable between the two groups (P>0.05) but significantly decreased compared with the pre-treatment scores in both groups (P<0.01). IIEF-5 score was also similar between the two groups (14.1-/+3.3 vs 14.3-/+5.0, P>0.05) but significantly increased compared with the pre-treatment scores in both groups (P<0.01). At the end of the eighth week, NIH-CPSI score was 7.8-/+2.2 and IIEF-5 score 20.1-/+4.4 in the trial group, which were significantly different from those at the end of the fourth week (P<0.01). In the control group, NIH-CPSI score was 12.7-/+2.3 and IIEF-5 score 14.3-/+4.5 at the eighth week, similar to those at the end of the fourth week (P>0.05). There were significant differences in NIH-CPSI and IIEF-5 scores between the 2 groups (P<0.01), and the change of NIH-CPSI score was negatively correlated with IIEF-5 score in the trial group (r=-0.89, P<0.01).

CONCLUSIONFor patients with CP/CPPS with erectile dysfunction, Huafenqinutang treatment in combination with vardenafil can effectively improve the erectile functions and decrease the NIH-CPSI score to favor the recovery from CP/CPPS.

To study the allele frequencies and their polymorphism characteristics of human platelet antigen (HPA) and human leucocyte antigen-I (HLA-I) in Chinese xi'an population, the types of HPA and HLA-I in 375 Chinese xi'an voluntary platelet donors were detected by PCR-SSP and PCR-SSO as well as flow cytometry with magnetic beads, and were analyzed. The results showed that there was no polymorphism in HPA-7-HPA-14, HPA-16 and HPA-17 which only expressed-aa type, the -bb type was only detected in HPA-3 and HPA-15, 9 out of 16 samples for the HPA-5ab phenotype simultaneously expressed HPA-15ab, the other 7 samples expressed HPA-15bb, no HPA-15aa phenotype was observed. Phenotypes detected in this study were HPA-1aa-17aa, HPA-1ab, -2ab, -3ab, -3bb, -4ab, -5ab, -6ab, -15ab and -15bb. Among 375 cases, HLA-A specificity of 16 species was observed, which accounted for 76% (16/21) of detectable phenotype specificity in this locus, moreover, 11 species showed frequency > 1%; HLA-B specificity of 36 species was observed which accounted for 84% (36/43) of detectable phenotype specificity in this locus, moreover 23 species showed frequency > 1%, these species were covered by common specific HLA-I in northern China, 264 species haplotype HLA-A-B were found in 375 cases, the frequency of 30 species was > 1%. It is concluded that the gene frequency distribution of HPA and HLA-I in Chinese Xi'an population is in accordance with population of northern China on the whole, but it has its own characteristics.

Objective To understand the pathogen detection of hospitalized patients before antimicrobial therapy in a hospital through implementation of comprehensive intervention measures,and provide reference basis for the de-velopment of targeted measures.Methods Hospitalized patients who received therapeutic antimicrobial agents in this hospital were selected as the research subjects.Patients who were hospitalized from January to May 2022 were selected as the pre-intervention group,comprehensive intervention measures were taken from June to October 2022,and those who were hospitalized from November 2022 to March 2023 were selected as the post-intervention group.The pathogen detection rate before antimicrobial therapy,sterile specimen detection rate,antimicrobial use rate,de-tection rate of key multidrug-resistant organisms of patients before and after the intervention were analyzed.Results Compared to before intervention,the proportion of pathogen detection rate before antimicrobial therapy(62.09％vs 74.04％),detection rate of healthcare-associated infection diagnosis-related pathogens(62.82％vs 92.73％),and sterile specimen detection rate(35.17％vs 41.06％)of hospitalized patients after intervention all increased signifi-cantly,with statistically significant differences(all P＜0.05).After intervention,pathogen detection rate before the combination use of key antimicrobial agents was not statistically different from before intervention(93.33％vs 90.48％,P＞0.05),while antimicrobial use rate was lower than before intervention(39.93％vs 44.95％,P＜0.05).There was no statistically significant difference in the detection rate of key multidrug-resistant organisms be-fore and after intervention(all P＞0.05).Conclusion Adopting scientific and rational intervention measures can improve the pathogen detection rate,provide a reference basis for the rational use of antimicrobial agents.There was no significant improvement in the pathogen detection rate before the combination use of key antimicrobial agents and the detection rate of key multidrug-resistant organisms,indicating that relevant measures still need to be further optimized.

OBJECTIVETo evaluate the efficacy of iloprost in acute vasodilatation test during cardiac catheterization and to explore a useful hemodynamic indication regarding operability in the patients with severe pulmonary hypertension (PH) related to congenital heart disease (CHD).

METHODSThe clinical data of 46 patients [mean age (12 ± 9) years] with severe PH related to CHD from June 2006 to December 2008 was retrospectively analyzed. All patients underwent standard right and left cardiac catheterization and a trial of inhaled iloprost test during cardiac catheterization. The mean pulmonary arterial pressure was (80 ± 13) mm Hg (1 mm Hg = 0.133 kPa) and pulmonary vascular resistance index was (17 ± 10) wood.m². A positive response to inhaled iloprost was defined as a decrease of at least 20% in pulmonary vascular resistance index (PVRI) without changes on systemic artery pressure. Patients with positive response to iloprost underwent cardiac surgical repair. The pulmonary artery pressure and PVRI was monitored by Swan-Ganz catheter postoperatively.

RESULTSOf the 46 patients, 29 (63.1%) showed a positive response after iloprost inhalation, defined by a significant reduction in PVRI from (15 ± 6) wood.m(2) at baseline to (9 ± 4) wood.m² in response to iloprost inhalation therapy (P < 0.05). The ratio of pulmonary to systemic resistance (Rp/Rs) decreased from 0.7 ± 0.2 to 0.4 ± 0.2 (P < 0.05). Seventeen patients (36.9%) didn't respond to iloprost displayed only little changes in PVRI [from (21 ± 10) wood.m(2) to (19 ± 9) wood.m²] and Rp/Rs (from 1.0 ± 0.5 to 0.9 ± 0.5). Out of 29 positive patients, 21 (72%) underwent successful cardiac surgical repair with a reduction of mean pulmonary arterial pressure (mPAP) to an average of (27 ± 10) mm Hg after the operation. Only 2 patients out of the 17 patients from the negative group were referred to surgery. Their mPAP was greater than 45 mm Hg.

CONCLUSIONSA significant reduction in pulmonary artery pressure after cardiac surgery was observed in patients with positive response to inhaled iloprost. Inhaled iloprost may be a valuable tool in the preoperative evaluation of patients with severe PH related to CHD.

Objective:To evaluate the efficacy and safety of adalimumab (ADA) in the treatment of Crohn′s disease (CD), and to analyze the predictive factors of ADA efficacy.Methods:From January 2020 to December 2020, 49 CD patients treated with ADA at the Department of Gastroenterology, Tenth People′s Hospital of Tongji University of Shanghai were enrolled. The clinical data before treatment were collected. During 12 weeks of ADA treatment, the patients were followed up every 2 weeks, the laboratory examinations were conducted every 4 weeks, and colonoscopy examination was rechecked at the 12th week. The improvement of the main symptoms of patients was assessed at 2nd, 4th, and 6th week during ADA treatment. At the 12th week after ADA treatment, the clinical response (Crohn′s disease activity index (CDAI) score decreased ≥70 points from baseline), clinical remission (CDAI score < 150 points), endoscopic response (simple endoscopic score for Crohn′s disease (SES-CD) decreased >50% from baseline) and endoscopic remission (SES-CD ≤2 points or Rutgeerts score ≤1 point), closure of anal fistula of CD patients complicated with anal fistula and occurrence of adverse reactions during treatment were recorded. The predictive factors of clinical remission of CD patients after ADA treatment for 12 weeks were analyzed. The Mann-Whitney U test and binary logistic regression analysis were used for statistical analysis. Results:The main symptom improved rates of 49 CD patients received ADA treatment at 2nd, 4th and 6th week were 75.5% (37/49), 95.9% (47/49) and 98.0% (48/49), respectively, and the main symptom improved time was 14.0 d (7.0 d, 17.0 d). After ADA treatment for 12 weeks, the clinical remission rate was 55.1% (27/49), the clinical response rate was 73.5% (36/49), the endoscopic remission rate was 43.3% (13/30), the endoscopic response rate was 55.6% (15/27), the anal fistula closure rate was 7/18, and the overall incidence of adverse reactions was 24.5% (12/49). The baseline of fecal calprotectin (FC) level of patients in the clinical remission group (27 cases) was lower than that of the patients in the active disease group (22 cases) (111.0 μg/g, 26.3 μg/g to 125.6 μg/g vs. 540.5 μg/g, 420.2 μg/g to 866.9 μg/g), and the difference was statistically significant ( Z=-4.44, P<0.001). The results of binary logistic regression analysis showed that baseline FC level was an independent predictive factor of clinical remission in CD patients treated with ADA for 12 weeks ( OR=1.08, 95%confidence interval 1.02 to 1.14, P=0.013). When the baseline FC cut-off value was 172.39 g/g, the sensitivity and specificity of it in predicting clinical remission in CD patients treated with ADA for 12 weeks were 81.48% and 90.91%, and the area under the receiver operator characteristic curve was 0.87 ( P<0.001). Conclusions:ADA is safe and effective in the treatment of CD. The baseline FC level is an independent predictive factor of clinical remission in CD patients treated with ADA for 12 weeks.

Objective To investigate the changes of matrix Metalloproteinases-9 (MMP-9) content in the cerebrospinal fluid of patients with brain injury and its clinical significance.Methods Sixty cerebrospinal fluid (CSF) specimens from patients with traumatic brain injury were chosen in our study as experimental group,and other CSF samples from 35 healthy subjects were selected as control group.The content of MMP-9 in cerebrospinal fluid was measured by enzyme-linked immunosorbent assay (ELISA) at 24 h and 72 h,1 and 2 weeks,respectively; and the comparative study was performed.Results The MMP-9 content in all CSF samples from the experimental group was significantly higher than that in the healthy control group (P＜0.05).Conclusion MMP-9 content in CSF of patients with brain injury increases obviously; MMP-9 in CSF may contribute to the severity of traumatic brain injury determination and guide the treatment strategies,which is worth for further study.

To explore differentially expressed genes in leukemia gene expression profile and identify main related genes in acute leukemia, gene expression profiles were analyzed in bone marrow/leucopheresis peripheral blood stem cells samples from 9 acute leukemia patients and their sibling donors with the use of oligonucleotide microarrays. 163 reported leukemia-related genes were involved in the study. The oligonucleotide primers were designed, synthesized and spotted on the chemical-material-coated-glass plates in array. The total RNAs were isolated from nine patients' bone marrow or leucopheresis peripheral blood cells and from nine their sibling donors peripheral blood stem cells treated by G-CSF, then collected by CS-3000 cell selection machine, and were reversely transcribed to cDNAs with the incorporations of fluorescent dUTP. The mixed probes were then hybridized to the oligonucleotide microarray. The results showed that in four patient/donor pairs with B-ALL, 5 up-regulated (RIZ, STK-1, T-cell leukemia/lymphoma 1A, Cbp/p300, Op18) and 1 down-regulated genes (hematopoietic proteoglycan core protein) were identified; In five patient/donor pairs with AML-M(4) and AML-M(5), 6 up-regulated (STAT5B, ligand p62 for the Lck SH2, CST3, LTC4S, myeloid leukemia factor 2 and epb72) and 1 down-regulated genes (CCR5) were identified. In conclusion, on the basis of distinguishing study of specific genetic related recipient/sibling donor pairs, screening leukemia-related genes with oligonucleotide microarrays, a set of 13 up-regulated or down-regulated genes among 163 leukemia-related genes has been identified. The result has further confirmed that above genes play critical role in the molecular mechanism of acute leukemia.

OBJECTIVETo investigate the outcome of video-assisted thoracoscopic extended thymectomy (VATET) for myasthenia gravis.

METHODSFrom January 2005 to February 2006, VATET had been performed for 41 patients of myasthenia gravis. Among them, 23 patients were female and 18 were male. The age ranged from 18 to 67 years old, and the disease duration ranged from 1 month to 3 years. In order to achieve maximal benefit, a transverse cervical incision was given access to the peri-thyroid space to remove fat in the neck which may contain ectopic thymus after all thymic tissue, including far-reaching ectopic sites. Peri-thymic adipose tissue in the anterior mediastinum was completely removed.

RESULTSIn the 41 patients, mean operative time was 162 min. Sever patients sustained myasthenic crises that required reintubation and mechanical ventilation for a few days. Of all patients, 35 had lymphadenectasis, and 4 had ectopic thymus in the peri-thyroid space. After the 2 years' follow-up, the rate of complete stable remission was 41.4%, and the effective rate was 85.4%.

CONCLUSIONSVideo-assisted thoracoscopic thymectomy represents a safe and valid approach for patients with myasthenia gravis. VATET may be a complement to completely remove all thymus including ectopic tissues.
