Objective To investigate the clinical characteristics and current condition of treatment for systemic lupus erythematosus (SLE) associated pulmonary arterial hypertension (PAH).Methods 10-year inpatients cases were reviewed and followed up.Cases were divided into 2 groups:group A:patients with baseline pulmonary arterial systolic pressure (PASP) lower than 70 mmHg; group B:patients with baseline PASP higher than 70 mm Hg.Pearson's correlation analysis,Chi-square test,Logistic regression,Cox-Mantel and Wilcoxon test were used for statistical analysis.Results There were totally 155 cases with 184 records of admission which accounted for 4.16% among total lupus cases.The main clinical characteristics included Raynaud's phenomenon (47.3%),pericardial effusion (41.9%) and high titer of anti-RNP antibody (55.4%).There were 132 cases enrolled for prognostic statistical analysis.There were 47 cases of death (35.6%) in total,among which 9 cases (19.1%) were in group A and 38 cases (80.9%) were in group B.In group A,there was a positive correlation between PASP and lupus disease activity index score.Single therapy analysis by Chi-square test showed that cyclophosphamide (CTX) (P<0.05) and PAH targeted drugs (P<0.01) were significantly associated with favorable outcome but logistic regressive analysis only confirmed the efficacy of target drugs (P<0.01).PAH target drugs significantly improved the one year survival rate of the severe cases.Conclusion The main clinical characteristics of SLE associated PAH include Raynand's phenomenon,pericardial effusion and positive anti-RNP antibody.The severity of PAH may not be related to lupus disease activity.PAH targeted drugs are effective in SLE-PAH.CTX may be effective in some cases.For severe cases,the combination therapy of CTX and PAH targeted drugs could significantly improve the prognosis.

Otjective To study whether there is the apoptosis of neural cells and the expressionof Bcl-2 protein in intracerebral hemorrhage (ICH) in model of rats, for the further understanding the mechanism of the delayed damage of the neural cells around the hematoma after ICH. Methods Fifty SD rats were randomly divided into 5 groups, ten in each. With the Group A as the control, the rest 40 were used to set up intracerebral hemorrhage model. The brains were taken out at 12th, 24th, 48th and 72th hours, respectively. Apoptosis cells were detected with terminal deoxynucleotidyl transferase mediated dUTP nick end labeling (TUNEL), and the expression of Bcl-2 protein was detected with immunochemical stainging methed (SP). Results In the control group, no apoptosis cells and Bcl-2protein were detected. In rest groups, the apoptosis cells and Bcl-2 protein were expressed in different degree.Apoptosis rates verified and corresponded with the time after ICH, with the peak at 48th -72th hour after hemorrhage.The peak rate of apoptosis cells was (24. 50± 2.69)% and Bcl-2 protein expression was (20. 76 ± 1.97)% . There was significant difference between the experimental groups and control (P<0.05), and no linear relationship between the apoptosis rate and the expression of Bcl-2 protein. Conclusion Apoptosis may be an important factor in the secondary trauma of ICH. There is a time leg after hemorrhage. All this is instructive to clinical treatment in time. Bcl-2 protein keeps increasing in a certain time after hemorrhage, but not synchronize with the cell apoptosis. This indicates that bcl-2 has the effect to reduce the apoptosis of neural cells.

From the aspects of advantages, barriers, opportunities and challenges, this paper analyzed the environmental factors of Shanghai medical resources serving people in the Pan-Yangtze River Delta. As envisaged by the author, such services will provide medical resources information to patients from outside Shanghai, probe into feasible ways to medical insurance based on experiences drawn from serving such patients, help with the resources integration of medical systems in Shanghai, and probe into the potentials of telemedicine and distant medical e-learning, as well as improve hospital management levels and service functionality.

Objective To design a microarray of ~60mer oligonucleotide for detection and sub-typing of human papillomavirus (HPV). Methods The type-specific oligonucleotide probes of 4 different types of HPV (6, 11, 16, 18) were designed by using biological software Arraydesigner 2.0, which analyzed the whole genome sequences of HPV and selected optimal probes with high specificity, identical length and similar melting temperature (Tm). These probes were synthesized and printed onto the surface of glass slides in order to prepare a low-density microarray. HPV samples were labeled with fluorescence dyes Cy3 using a method of restriction display PCR (RD-PCR). HPV plasmid DNA was restricted with Sau3AⅠ to produce multiple fragments which were ligated to adaptors subsequently and used as PCR template. PCR labeling was performed with the fluorescently labeled universal primer (Cy3-UP) whose sequence is designed according to the adaptor of the RD-PCR approaches. The labeled samples were then hybridized with the oligonucleotide microarray. Results Both single and multiple HPV DNA samples could be detected with oligonucleotides microarray, and the corresponding HPV subtypes were recognized as well. And no signals were detected in all the negative and blank control spots. Conclusion 60mer oligonucleotide microarray designed by appropriate bioinformatics software can be applied to HPV detection and genotyping on gene level.

Objective To evaluate the value of double stapling technique with curved cutter stapler in colorectal anastomosis,especially in low colorectal anastomosis. Methods The clinical data of 168 cases of rectal carcinomas treated with double stapling technique with curved cutter stapler were retrospectively reviewed.The intraoperative condition,postoperative complications and findings during follow up were analysed. Results During the operations,the processes of closure and anastomosis of all the patients were satisfactory,and no operative death occurred.After the operations,4 cases(2.4%) had anastomotic leakage,3 cases(1.8%) had anastomotic bleeding,and 2 cases(1.2%) had rectovaginal fistula.All the complications were cured.There was no anastomotic stricture. Conclusion Double stapling technique with curved cutter stapler may help to accomplish low colorectal anastomosis which is a difficult task for handed suture.

Objective To study the screening value of color doppler flow imaging (CDFI) for gastroesophageal reflux(GER).Methods Through the window of left lobe liver, the abdominal esophageal length,the phenomenon of GER and the frequency of GER were detected by CDFI in 55 children with GER and 55 control group.Results Abdominal esophagus was identified by CDFI in every children. The abdominal esophageal length was shorter in refluxers than that in control group. A significant correlation was found between its length and the age of control group.To diagnose GER with CDFI ,its accuracy was 98.18%,and its specificity was 76.36%.Conclusions Visualization and measurements of the abdominal esophagus are readily achieved with CDFI in children.Abdominal esophageal length is shorter in refluxers than that in control group. CDFI is a rapid method of screening GER.
