OBJECTIVETo investigate the clinical characteristics of patients with idiopathic pulmonary arterial hypertension (IPAH) in China.

METHODSA total of 161 patients diagnosed as IPAH in Shanghai Pulmonary Hospital from June 2008 to June 2010 were retrospective analyzed.

RESULTSThe mean diagnostic age was (33 ± 15) years old and 70.2% patients were female. The median duration from symptoms onset to diagnostic right heart catheterization was 12 months. Incidence of NYHA class III to IV was 56.5% at diagnosis and the mean six minutes walk distance was limited to (398 ± 108) meters. Incidence of mild obstructive, restrictive and diffusing impairment in pulmonary function test was 7.8%, 42.2% and 82.2% patients with IPAH, respectively. Right heart catheterization demonstrated severe elevated mean pulmonary arterial pressure [(63 ± 17) mm Hg (1 mm Hg = 0.133 kPa)] and pulmonary vascular resistance index [(25 ± 12) Wood U/m(2)] in this patient cohort. The response rate of acute pulmonary vasoreactivity testing was 8.7% in this cohort. Compared with non-responders, responders to acute pulmonary vasoreactivity testing were younger and with less severe pulmonary hypertension. Among non-responders, 89% patients were treated by one specific anti-pulmonary arterial hypertension drug and 27% patients received combined anti-pulmonary arterial hypertension medications.

CONCLUSIONSYoung female was predominantly involved in patients with IPAH in China. The diagnosis of IPAH is often made at advanced disease stage and majority patients with IPAH received specific anti-pulmonary arterial hypertension therapies in this patient cohort.

Objective To investigate the gene mutations of calcium-and integrin-binding protein 2 (CIB2) 196C＞T, 272T ＞ C and 297C ＞ G carried by students with non-syndromic hearing impairment from special educational schools in Yunnan Province. Methods The experimental group included 337 students with non-syndromic hearing impairment who failed to carry deafness gene with GJB2 (35 del G, 176_191 del 16,235delC, 299_300 del AT), GJB3 (C538T,G547A), mtDNA 12S rRNA (A1555G, C1494T), and SLC26A4 (IVS7_2A＞G, A2168G) . The control group consisted with 150 healthy people. Genomic DNA was isolated from peripheral blood with EDTA anti-coagulate. The subject's DNA fragments including CIB2 196C＞T, 272T ＞ C and 297C＞ G were amplified by polymerase chain reaction (PCR), and subsequently analyzed by direct sequencing to identify deafness-associated mutations. Results Both in the experimental group and control group, we failed to find the mutation of CIB2 196C＞T, 272T＞C and 297C＞G in all individuals. Conclusion Mutations in CIB2 gene 196C＞T, 272T＞C and 297C＞G are not a frequent cause of non-syndromic hearing loss among deaf people in Yunnan province. It provided important information for deafness with formulating landscape of gene screening in this region.

OBJECTIVETo investigate the relationship between the polymorphic (AT)n repeats in 3ountranslated region of exon 4 of CTLA4 gene [CTLA4(AT)n] and Graveso disease (GD) in Zhuang nationality population of Guangxi province.

METHODSThe studied groups comprised 48 patients with GD and 44 normal controls. Amplification of target DNA was carried out by polymerase chain reaction (PCR). The amplified products were run by 8% polyacrylamide gel electrophoresis, and then followed by 0.1% silver staining. Some of amplified products were sequenced directly.

RESULTSNineteen alleles of CTLA4 gene microsatellite polymorphism were found in Guangxi Zhuang nationality individuals. The 106 bp long allele was apparently increased in patients with GD of Zhuang nationality but not in healthy controls (P< 0.05).

CONCLUSIONCTLA4 gene microsatellite polymorphism is strongly associated with Graveso disease in Zhuang nationality population of Guangxi province. CTLA4(AT)n 106 bp may be the susceptible gene in GD patients of Zhuang nationality in Guangxi; 19 alleles of CTLA4 gene microsatellite polymorphism were found in Guangxi Zhuang nationality individuals.

OBJECTIVETo evaluate the clinical efficacy and safety of the treatment of osteonecrosis of the femoral head by percutaneous decompression and autologous bone marrow mononuclear cell (BMCs) infusion.

METHODS44 hips in 28 patients with avascular necrosis at early stage were treated by percutaneous multiple holes decompression followed by autologous BMCs infusion. Autologous BMCs were concentrated from bone marrow that was taken from the posterior iliac crest of the patient. Patients were followed up at least 2 years. The results were determined by the changes in the Harris hip score and the progression in the radiograghic stages.

RESULTSNo complications were observed after the operation. Before operation, there were stage I of femoral head necrosis in 8 hips, stage II in 15 hips, stage III in 14 hips, stage IV in 7 hips, and the postoperative stages at the most recent follow-up were stage O in 1 hip, stage I in 6 hips, stage II in 13 hips, stage III in 13 hips, stage IV in 7 hips, stage V in 4 hips. The mean preoperative Harris hip score was 58 (46-89), and improved to 86 (70-94) postoperatively. All the femoral head collapsed preoperatively showed that the necrotic size was at least more than 30%.

CONCLUSIONSPercutaneous multiple holes decompression combined with autologous BMCs is a new way to treat avascular necrosis of the femoral head. The earlier the stage, the better the result. A randomized prospective study needed to compare with routine core decompression in the future.

OBJECTIVEThe primary aim of this prospective study was to use serial (18)F-FDG PET-CT imaging to evaluate the trend of the tumor's maximum standardized uptake value (SUVmax) during radiotherapy (RT) for patients with nasopharyngeal carcinoma (NPC), and to explore the possibility of early evaluation of the tumor bio-metabolic response during radiotherapy.

METHODSSixty patients with biopsy-proven primary NPC were prospectively enrolled into the study. All patients underwent four (18)F-FDG PET-CT scans: one initial scan before RT/cisplatin based concurrent chemoradiotherapy, at the point of 50 Gy during RT, the end of RT, and one month after RT, respectively. Tumor (18)F-FDG uptake was analyzed according to the World Health Organization pathological type.

RESULTSThere was a significant difference (P < 0.001) of the mean of SUVmax of the primary site among pretreatment (11.20 ± 5.37) and posttreatment at the dose of 50 Gy (3.50 ± 1.59), at the end of RT (3.05 ± 1.56) and one month after RT (2.52 ± 1.46). There was also a significant difference (P < 0.001) of the mean of SUVmax of neck node site. However, there was a significant difference of the SUVmax between histological WHO type IIb and type IIa in the primary site (P = 0.046) [(67 ± 19)% reduction at dose 50 Gy for type IIb vs. (55 ± 24)% for type IIa] but not in the lymph nodes.

CONCLUSIONSEarly PET scan during or right after RT instead of conventional 3 months interval after RT is indicated to evaluate the tumor response and to develop individualized adaptive radiotherapy in NPC. Our next study will attempt to demonstrate the results based on long-term follow-up data.

OBJECTIVETo investigate the effectiveness of testicular sperm cryopreservation in male fertility preservation by evaluating the clinical outcome of ICSI cycles with frozen-thawed testicular sperm for azoospermia patients.

METHODSWe retrospectively analyzed 96 samples of cryopreserved testicular sperm obtained by testicular biopsy, vasovasostomy (V-V), vasoepididymostomy (V-E) , of which 55 were subjected to 60 ICSI cycles with frozen-thawed testicular sperm. We evaluated the rates of sperm recovery, fertilization, cleavage, transferable and good-quality embryos, clinical pregnancy, pregnancy outcome, and health of the newborns.

RESULTSAll the frozen testicular sperm samples were recovered successfully. The rates of fertilization, 2PN fertilization, cleavage, available embryos and good-quality embryos were 77.6, 69.4, 99.4, 84.5 and 40.8%, respectively. There were transferable embryos in all cycles. Fresh embryos were transferred in 52 of the 60 cycles, with the clinical pregnancy rate of 57.7% (30/52), including 19 singletons and 11 twins, and the rates of implantation and miscarriage were 38.7% (41/106) and 3.33% (1/30). Up to the present time, there have been 20 healthy newborns, including 12 boys and 8 girls, and another 13 ongoing pregnancies. No birth defects have been found so far.

CONCLUSIONDesirable clinical outcomes can be obtained from ICSI cycles with frozen-thawed testicular sperm, and testicular sperm cryopreservation is an effective method of fertility preservation for azoospermia males.

OBJECTIVETo explore the infarct sites in patients with inferior wall acute myocardial infarction (AMI) concomitant with ST segment elevation in leads V1-V3 and leads V3R-V5R.

METHODSFive patients diagnosed as inferior, right ventricular, and anteroseptal walls AMI at admission were enrolled. Electrocardiographic data and results of isotope 99mTc-methoxyisobutylisonitrile (MIBI) myocardial perfusion imaging and coronary angiography (CAG) were analyzed.

RESULTSElectrocardiogram showed that ST segment significantly elevated in standard leads II, III, aVF, and leads V1-V3, V3R-V5R in all five patients. The magnitude of ST segment elevation was maximal in lead V1 and decreased gradually from lead V1 to V3 and from lead V1 to V3R-V5R. There was isotope 99mTc-MIBI myocardial perfusion imaging defect in inferior and basal inferior-septal walls. CAG showed that right coronary artery was infarct-related artery.

CONCLUSIONSThe diagnostic criteria for basal inferior-septal wall AMI can be formulated as follows: (1) ST segment elevates > or = 2 mm in lead V1 in the clinical setting of inferior wall AMI; (2) the magnitude of ST segment elevation is the tallest in lead V1 and decreases gradually from lead V1 to V3 and from lead V1 to V3R-V5R. With two conditions above, the basal inferior-septal wall AMI should be diagnosed.

OBJECTIVEThis study was sought to compare the sensitivity, specificity and accuracy of (1) dual isotope simultaneous acquisition single-photon emission computed tomography (DISA SPECT) myocardial image with (99m)Tc-sestamibi/(18)F-fluorodeoxyglucose ((99m)Tc-MIBI/(18)FDG); (2) low dose dobutamine alone and combined with Isosorbide Dinitrate (ISDN: Isoket) stress two dimensional echocardiography (2DE) to predict regional movement recovery after revascularization (CRV) in patients with old myocardial infarction (OMI) and severe left ventricular dysfunction.

METHODSTwenty-six patients (mean age 51 +/- 8 years, male 25, female 1) with OMI and severe left ventricular dysfunction (mean left ventricular ejection fraction, LVEF (38.6% +/- 4.9%) underwent low dose dobutamine 10 microg x kg(-1) x min(-1) (Dob10 microg) and ISDN (286 +/- 31 microg/min) combined with Dob5 microg (ISDN-Dob 5 microg) 2DE and DISA SPECT within one week. In echocardiogram and DISA SPECT images: the left ventricle (LV) was divided into 16 segments. The semi-quantitative scoring system was used for both images. Myocardial viability was defined as an improvement of at least >or= 1 grade in at least two contiguous segments at rest 2DE after CRV. The viable segments detecting rate with stress 2DE and DISA SPECT were compared. Compared with the results of post-CRV, the sensitivity, specificity and accuracy of detecting viable segments of two methods were calculated.

RESULTSAmong 272 abnormal segments in 26 patients, 156 (57.4%) segments showed contractile improvement after CRV. The viable segments detecting rate with DISA SPECT was 72.4% (134/254), which was significantly higher than the contractile improved rate after CRV (P < 0.001). During Dob10 microg 2DE and ISDN-Dob5 microg 2DE, the detecting rates were 65.5% (163/249) and 65.7% (176/268), respectively, which were both comparable to the improved rate after CRV (both P > 0.05). With DISA SPECT, the sensitivity, specificity and accuracy were 93.7%, 55% and 76.8%, respectively. Compared with DISA SPECT, Dob10 microg 2DE showed similar sensitivity (88.6%), specificity (64.2%) and the accuracy (77.9%). When ISDN combined with Dob5 microg, the sensitivity (91.4%), specificity (68.1%) and accuracy (81.4%)were comparable to those of Dob10 microg 2DE and DISA SPECT (all P > 0.05), while the specificity was even higher than DISA SPECT (P < 0.05).

CONCLUSIONIn identifying myocardial viability in patients with OMI and severe left ventricular dysfunction, DISA SPECT has higher sensitivity, lower specificity and better accuracy. Dob10 microg and ISDN-Dob5 microg 2DE are both equivalent to DISA SPECT in sensitivities, specificities and accuracies, and even higher in specificity in ISDN-Dob5 microg 2DE.
