Objective To investigate the risk factors for severe and mild preeclampsia (PE) in women with irregular prenatal care,and to identify practical measures to reduce the occurrence of severe PE.Methods A retrospective study of 222 PE patients with irregular prenatal care,who delivered in Peking University Third Hospital from January 2007 to December 2011,was performed.The risk factors for PE and the status of prenatal care were analyzed.The non-parametric test,Chi-square test,Fisher's exact test,trendy Chi-square test and Logistic regression analysis were used for statistical analysis.Results There were 207 (93.2％) cases of severe PE and 15 (6.8％) cases of mild PE.In 207 severe PE patients,there were 95 cases (45.9％) of early-onset PE (diagnosed before 32 gestational weeks) and 112 cases (54.1％) of late-onset PE.In the 15 mild PE patients,there were two early-onset cases and 13 late-onset cases.The percentage of early-onset cases in severe PE patients was higher than that in mild PE patients [45.9％ (95/207) vs 2/15,x2=6.027,P=0.015].After excluding 9 cases without any prenatal care,213 PE patients were analyzed,and it was found that the proportion of severe PE diagnosed in hospitals of grade 3,2 and 1 were significantly different [5/9,94.2％ (131/139) vs 96.9％ (63/65),x2=8.600,P=0.003].Compared with mild PE patients,the prenatal care interval for PE diagnosis in severe PE patients was longer [M(Q),8.0(4.0) vs 4.8(4.4) weeks,Z=2.695,P=0.007];the frequency of prenatal care after 20 gestational weeks was less [1(1) vs 3(3) times,Z=-4.195,P=0.000];the gestational week of PE diagnosis and referral to grade 3 hospitals were earlier [32.4(5.6) vs 35.4(4.3) weeks,Z=-3.075,P=0.002;33.1(5.3) vs 35.4(3.9) weeks,respectively,Z=-2.608,P=0.009];and the interval between PE diagnosis and referral was longer [0.1 (0.7) vs 0.0(0.0) weeks,respectively,Z=2.904,P=0.004].Multivariate logistic regression showed that the frequency of prenatal care after 20 gestational weeks was an independent risk factor for severe PE (OR=0.115,95％CI:0.046-0.285,P=0.000).Conclusion In women without regular prenatal care,the onset of severe PE is related to low-level prenatal hospital care,lack of prenatal care after 20 gestational weeks and longer prenatal care intervals as well as referral to grade 3 hospitals.

Objective To investigate the 5-and 10-year survival and complications of patients with stage Ⅱb cervical carcinoma treated by pre-operative photon radiotherapy (POPRT) plus brachytherapy (192Ir) and selective lymphadenectomy hysterectomy (SLH) plus intra-operative electron radiotherapy (IOERT). Methods From February 1997 to May 2007, 160 patients with stage Ⅱb cervical carcinoma were treated by POPRT of 20 Gy in 10 fractions to the whole pelvis, 192Ir brachytherapy of 14 Gy in 2fractions, followed by IOERT of 18 -20 Gy to the whole pelvis during SLH one week after. Results The follow-up rate was 98.1%. The number of patients followed-up for 5 and 10 years was 143 and 135,respectively. The 5-year overall survival rate, disease-free survival rate and local control rate of all patients were 89.4%, 86. 3% and 96. 3%, with the corresponding 10-year rates of 84.4%, 81.0% and 95.0%,respectively. The radiation-induced rectitis and cystitis were 5.0% and 0. 6%, respectivly. The rate of hydronephrosis and lower extremity edema was 6. 3% and 1.3%, respectively. Conclusions Combination of EBRT plus 192Ir brachytherapy and SLH plus IOERT could improve the survival and local control of patiens with cervical carcinoma, with only a few side effects.

In recent years, more and more research shows that the pharmacokinetic parameter of traditional Chinese medicine can be affected by the disease states. It's possible that drug metabolic enzymes, transporters, cell membrane permeability and the change of microbes group could be interfered with physiological and pathological changes, which enables the pharmacokinetics of traditional Chinese medicine in the body to be altered, including the process of absorption, distribution, metabolism and excretion, and then the pharmacokinetic parameters of traditional chinese medicine are altered. It's found that investigating the pharmacokinetic of traditional Chinese medicine in the pathological state is more useful than that of in normal state because the great part of traditional Chinese medicine is mainly used to treat disease. This article reflects the latest research on the pharmacokinetic of traditional Chinese medicine in the disease state such as diabete, cerebral ischemia, liver injury, inflammatory disease, nervous system disorders and fever in order to provide certain reference for clinicians designing reasonable administration dose.

Objective To evaluate the development of immature oocytes after freezing-thawing by conventional cryopreservation method for mature oocytes.Methods Immature oocytes were collected from stimulated ovaries of intracytoplasmic sperm injection(ICSI)cycles.Immature oocytes were in vitro matured directly or after slow freezing-fast thawing and immunostained for tubulin and chromatin and at last visualized by confocal microscopy.Results No statistical difference was found in maturity rate between freezing groups and the controls.There was a statistically significant increase in abnormalities of chromosome(23.7% vs. 50%)and spindle(28.9% vs.53.9%)in the GV freezing group compared with the GV control(P

Objective To compare the effects of vitrification with slow-freezing on the developmental ability of day 3 cleavage stage embryos.Methods Patients who had no less than 4 high quality embryos were included in this study.These embryos were cryopreserved using the methods of vitrification or slow-freezing.In the eryopreserved embryo transfer cycles,the embryos which were cryopreserved using one of the methods were chosen randomly.The developmental ability of embryos was compared between these two groups.Results A total of 80 patients were included in this study with 160 embryos.In the group of slow-freezing,73(91%)embryos were survived and achieved 15(38%)clinical pregnancies.Among these,3 were twins and the implantation rate was 25%(18/73).In the group of vitrification,71(89%)embryos were survived and achieved 19(48%)clinical pregnancies.Among these, 9 were twins and the implantation rate was 39%(28/71),which was significantly higher than the slow- freezing group(P

Aim To observe the effect of hemodialysis on pharmacokinetics of sparfloxacin in thepatients contracting chronic renal failure. Methods Sparfloxacin concentrations inserum and urine of hemodialysis and non-dialysis patients were measured with a highperformance liquid chromatography method after administration a single oral dose of 200mg sparfloxacin. The pharmacokinetic parameters were computed with the programPKBP-N1.Results The main pharmacokinetic parameters in hemodialysis group wereT1/2(ka) - (1. 25 ?0. 57) h, T1/2(?) = (11. 88?4. 13) h, Tpeak = (4. 18 ? 0. 78) h,Cmax = (0.80 ? 0. 17) mg? L-1 and AUC0-= (6. 90 ? 3. 25) mg?h?L-1, while innon-dialysis group were T1/ 2(ka) = (1. 12 ? 0. 42) h, T1/ 2(?) = (15. 93 ? 5. 20) h, Tpeak =(3. 88 ? 0. 75) h, Cmax = (0. 69 ? 0. 37) mg?L -1, AUC0-= (10.05 ? 4. 13) mg?h?L-l. The original sparfloxacin discharge rats in urine within 24 h were (8. 98 ? 3. 92) % and(10. 58 ? 5. 64) % separately. T1/2(?) and AUC in hemodialysis group were markedly lowerthan in non-dialysis group (P

Literatures on pain intervention with transcutaneous electrical acupoint stimulation (TEAS) were collected by searching the databases both in Chinese and English, and summarized to understand the research progress of TEAS effects on pain mediators in recent years. This will provide a more objective and scientific theoretical basis for clinical practice of TEAS to treat pain syndrome, thus promoting the clinical application of TEAS. Our literature analysis indicated that TEAS effectively regulated the release levels of various pain factors such as prostaglandin, 5-hydroxytryptamine, interleukins, substance P and tumor necrosis factor-α to achieve the analgesic effects by affecting the conduction pathways. TEAS is a safe, non-invasive and effective treatment for pain syndrome. However, further research is necessary due to the lack of rigor of the current clinical trial design.
