Objective To determine the safety, pregnancy outcome and the affect on neonates in pregnant patients with systemic lupus erythematosus(SLE).Methods Sixty-two pregnant patients with SLE were evaluated retrospectively from 1999 to 2009 in our hospital. These patients were divided into two groups:selective pregnancy group and nonselective pregnancy group. The pregnancy outcomes, fetal outcomes, and lupus activity during pregnancy were compared between the two groups. The children of the SLE patients were followed up. Results There were 43 patients in the selective pregnancies group and 19 patients in nonselective pregnancies group. In the selective pregnancies group, lupus flare occurred in 10 pregnancies(23%), 35(81%)had a live birth, 7 had low birth weight infants and 7 had premature delivery; however, in the nonselective pregnancies group, lupus flare occurred in 16 pregnancies(84%), 13(68%) had abortion,6 had a live birth, but all neonates were low birth weight infants. The rates of lupus flare and pregnancy loss in the nonselective pregnancy group were higher than those of the selective pregnancy group(P＜0.05). None of the 22 children had SLE during the follow-up period. Conclusion Both selective and nonselective pregnancy may adversely affectmaternal and fetal outcomes, but patients with selective pregnancy have better outcomes either in lupus flare or maternal and fetal outcomes compared with those of the nonselective pregnancy.

To compare the clinical effect of phacoemulsification and middle incision extracapsular cataract extraction ( Ml-ECCE) . METHODS: One hundred and eighty - five eyes of phacoemulsification (137 cases) and 185 eyes of 139 cases for Ml-ECCE from January 2011 to May 2013 were involved in this study. And the ratio posterior capsular rupture during surgery, visual acuity, corneal edema, corneal astigmatism and intraocular pressure post operation were followed up.RESULTS: On 1d after surgery, uncorrected visual acuity in the group of Ml-ECCE was better than that of phacoemulsification group, while from 3d; 1 and 3mo after surgery, no significant difference was found from the above two groups. On 1d postoperation, corneal edema ratio in phacoemulsification group ( 45 eyes ) was higher than that in Ml-ECCE group(20 eyes) ( X2=11. 665, P=0. 0006 ) . No significant difference was found for the ratio of posterior capsule rupture during surgery in these two surgical technique groups(X2=0. 094,P=0. 759). On 1wk;1 and 3mo after surgery, significant difference was found for the average of surgical induced corneal astigmatism between two groups (u=6. 661, 6. 880, 4. 187, P = 0. 00, respectively ). During following up, no significant difference was found for the intraocular pressure between two groups ( u=1. 858, 0. 963, 0. 471, 1. 349, 1. 388; P= 0. 063, 0. 335, 0. 638, 0. 177, 0. 165). lntraocular pressure on 1d postoperation in phacoemulsification and Ml-ECCE groups was higher than before operation ( u = 19. 86, 19. 39, P = 0. 00, respectively). And on 1wk; 1 and 3mo postoperation, intraocular pressure in the operated eyes in both groups was lower than before operation for 2~3mmHg.CONCLUSlON: Although phacoemulsification and Ml-ECCE could both get good visual rehabilitation, with similar visual outcome, no significant effect for intraocular pressure, and no severe complications, the latter one owns the advantage that easier maneuver, quicker recovery, and cheaper instruments needed, which is suitable for the hard nuclei cataract in local hospitals. Ml-ECCE is a safe, effective and easy manipulation for local hospital for large batch of cataract surgeries.

Objective To explore the value of improved elasticity scores in differentiating malignant and benign breast lesions. Methods A prospective study was done in 394 patients with 508 breast lesions confirmed by pathology and the elastographic images of the lesions were evaluated by using old and improved elasticity scores respectively. Results The elastographic images of the lesions could be evaluated and classified in all patients by improved elasticity scores but could not be evaluated and classified in 82 lesions by old elasticity scores. The accuracy of ultrasonic elastography for diagnosing benign and malignant breast lesions was 88.8% and 78.1%, respectively by old elasticity scores and improved elasticity scores. Conclusions The elastographic images of breast lesions were accurately evaluated by using improved elasticity scores, and the use of improved elasticity scores is helpful to reduce the biopsy which is not necessary.

Aim This study was designed to investigate the inhibition of matrine on U251 glioma cell line and its mechanism. Methods MTT was used to measure the levels of the proliferation of U251 cultured with matrine in different concentrations.The effects of matrine on cell cycle of U251 were observed by FCM. The expression of proto oncogenes c myc was measured by RT PCR. Results The proliferation of U251 was obviously inhibited by matrine in a dose dependent manner. The inhibitory rate was (53 7?6 0)%,when cultured with matrine at 0 10 g?L -1 . The outcome of FCM showed that the proportion of G 0/G 1 phase cells were decreased. The proportion of S phase cells were reduced obviously,when cultured with matrine at 0 10 g?L -1 in 3 days.The outcome of RT PCR showed that the expression of proto onco gene C myc was notably decreased, when the dose of matrine was increased. Conclusion Matrine can inhibit the proliferation of U251 and inhibit the expression of proto onco gene C myc.

Objective To investigate the diagnostic value of strain ratio for differentiation breast benign and malignant solid lesions. Methods Two hundred and sixty-nine patients with 377 lesions (278 benign, 99 malignant) were included in the study. Ultrasonography found the lesions, then ultrasonic elastography got the strain images. By the strain ratio measure method equipped with the ultrasonic machine, strain ratio of the lesion was calculated. Compared with the pathologic diagnosis, the cut-off point of strain ratio was determined with receiver operating characteristic curve. Results There was significant difference between the strain ratio of benign and malignant lesions( P <0. 05). The cut off point of strain ratio was determined as 3. 08, Youden's index was 0. 88,sensitivity was 97. 38% ,and specificity was 91. 33%. Conclusions Strain ratio could be used to differentiate benign and malignant lesions in breast and would be a new diagnostic standard in future.

Objective:To observe the correlation between the B7 blocker,CD28 and cytotoxic T lymphocyte-associated antigen 4 immunoglobulin (CTLA-4Ig) impacting on Th17 and Treg cells expressed in the spleen of lupus mice and its intervention role in lupus-like symptoms of B6.MRL-Faslpr/J lupus mice.Methods:Sixteen 4-month-old female B6.MRL-Faslpr/J mice were selected and randomly divided into treatment group ( groupⅠ) and control group ( groupⅡ);injected the same amount of CTLA-4Ig and PBS intra-venously,checked their 24 hour urine protein ,ANA antibody,ds-DNA antibodies before and after the intervention.Two weeks after the intervention ,detected serum IL-17A,and the percentage of Th17 and Treg cells in their spleen.Results:Two weeks after the last inter-vention,24-hour urine protein,serum ANA and ds-DNA in groupⅠdecreased,and all the differences were statistically significant (P<0.05) compared with groupⅡ.Two weeks after the last intervention,serum IL-17A and the proportion of Th17 cells in the spleen in groupⅠwere lower than those in groupⅡ, but Treg cells in CD4+T lymphocytes was higher than that in groupⅡ,all the differences were statistically significant ( P<0.05).Conclusion:CTLA4-Ig can relieve the lupus-like symptoms in lupus mice;raising the number of Treg cells and decreasing the number of Th17 cells may be one of the important mechanisms for CTLA-4Ig to alleviate lupus-like symptoms in B6.MRL-Faslpr/J mice.

Objective To systematically assess the efficacy and safety of non-indwelling urinary catheter during perioperative period of cesarean section.Methods The databases including Medline(PubMed),EMbase,Cochrane Library,CNKI and WanFang Data were retrieved by computer.The randomized controlled trials (RCTs) on the efficacy and safety of non-indwelling urinary catheter during perioperative period of cesarean section were comprehensively collected.Two reviewers independently screened literatures,extracted the data and assessed the quality.The Meta-analysis was conducted by using RevMan 5.3 software.Results A total of 5 RCTs involving 1 090 patients were included.The meta-analysis results showed that compared with the indwelling urinary catheter group,although the non-indwelling urinary catheter group increased the incidence rate of urinary retention[RR=11.67,95%CI(2.22,61.24),P<0.01],but significantly decreased the incidence rate of urinary tract infection(UTI) [RR=0.10,95%CI(0.04,0.26),P< 0.01] and incidence rate of initial urination discomfort [RR=0.17,95%CI (0.04,0.74),P=0.02],significantly shortened the initial time of off-bed activities [SMD=-3.68 ,95%CI(-5.25,-2.12),P<0.01]and hospitalization time [SMD=-1.03,95%CI(-1.67,-0.38),P<0.01].There were no significant differences in the operation time[SMD=-0.13,95%CI(-0.32,0.07),P=0.20] and incidence rate of postpartum hemorrhage (PPH)[RR=1.50,95%CI (0.43,5.26),P=0.53],The incidence rates of bladder injury in the two groups were similar.Conclusion According to the evidence of current clinical researches,selecting non-indwelling urinary catheter in elective cesarean section is effective and safe,prompting that indwelling urinary catheter during the perioperative period of cesarean section is selective rather than routine indwelling.

AIM: To investigate the inhibitory effect of TanshinoneⅡA on U251 glioma cell line and its mechanism. METHODS: MTT was used to measure the levels of the proliferation in U251 cultured with TanshinoneⅡA at different concentrations. The effects of TanshinoneⅡA on cell cycle of U251 were observed by FCM. The expression of proto-oncogene c-myc was measured by RT-PCR. RESULTS: The proliferation of U251 was obviously inhibited by TanshinoneⅡA in a dose dependent manner. The inhibitory rate came to the peak at (54 2?0 9)%, when cultured with TanshinoneⅡA at 0 10 g/L. The outcome of FCM showed that the proportion of G 0/G 1 phase cells was increased and the proportion of S phase cells was reduced obviously, when cultured with TanshinoneⅡA at 0 10 g/L for 3 days. The RT-PCR experiment showed that the expression of proto-oncogene c-myc was notably decreased, when the dose of TanshinoneⅡA was increased. CONCLUSION: TanshinoneⅡA inhibited the proliferation of U251 and the expression of proto-oncogene c-myc.
