Objective To provide references for clinical rational use of Chinese patent medicine. Methods Totally 387 specifications of Chinese patent medicine in our hospital were analyzed, and were judged by pregnancy contraindication according to China Pharmacopeia (2010 edition). Results The 387 Chinese patent medicines involved 32 prohibited pregnancy ingredients, 1 taboo ingredient. In 89 Chinese patent medicines contraind prohibited ingredients, 33 marked prohibited ingredients, 18 marked contraindicated ingredients, 14 marked cautious ingredients, and 24 marked without-contraindication ingredients. 68 Chinese patent medicines contained pregnancy contraindication labels but without prohibited ingredients. Conclusion A unified standard of pregnancy contraindication should be established;researches on pregnancy contraindication should be strengthened;medicine specifications should be standardized and perfected.

Genetic factors are the important reasons for birth defects.Among genetic factors,chromosome abnormality is the most common.Prenatal diagnosis can effectively avoid fetus of abnormal chromosome being born.Noninvasive prenatal diagnosis has more advantage than invasive prenatal diagnosis,such as non-invasive,painless and safe.It is bound to become the main method of prenatal diagnosis.However,non-invasive prenatal diagnosis is still in its infancy stage and the accuracy and sensitivity of detection are pending and need further clinical validation.This article will present a variety of non-invasive prenatal diagnostic methods using cell-free fetal DNA (RNA) and their advantages and disadvantages will be discussed.

Objective To evaluate the change of left ventricular(LV) function by real-time three dimensional echocardiography(RT-3DE) and to explore the clinical value of change of serum adiponectin level in patients with metabolic syndrome (MS).Methods One hundred and twenty patients were divided into MS group and control group according to the diagnostic standard of the nternational Diabetes Federation.Transthorasic 2D ultrasound and RT-3DE examination were performed in all study objects, and serum adiponectin levels were measured.Results Parameter index [including Tmsv16-SD, Tmsv12-SD,Tmsv16- Dif, Tmsv12-Dif, Tmsv16-SD (％), Tmsv 12-SD (％), Tmsv16-Dif (％), Tmsv12-Dif (％)] of 17segment time to minimal systolic volume in MS group was more than that in control group (all P ＜0.05).Some regional systolic index of LV and serum adiponectin level were less than that in control group (all P ＜0.05).Compared with the control group, E/E' was lower (P ＜ 0.05).There were significant relations between serum adiponectin level and E/A of mitral valves, E'/A' of mitral annulus and E/E'(r = 0.368,0.493,and -0.347 respectively, P ＜0.05).Conclusions RT-3DE can rapidly evaluate LV systolic and diastolic synchrony in MS patients.E/E' show an excellent correlation with serum adiponectin level,and it may be a new promising method for routine evaluation of LV diastolic function.

Objective To study the value of thromhus precursor protein(TpP)in early diagnosis of acute ischemic cerebrovascular disease.Methods The patients who showed completely or partly anterior circulation infarcts syndrome and were within 6 hours from onset on admission were observed dynamically.All patients were divided into thrombotic cerebral infarction(TCI)group(40 cases),transient ischemic attack (TIA)group(42 cases), and lacunar infarction(LI)group(37 cases).Concentrations of TpP in plasma obtained from three groups on admission were detected by enzyme linked immunosorbent assay(ELISA),then were compared with each other.The diagnostic value of plasma TpP to TCI within 6 hours from onset was analyzed with ROC curve.Results The level of TpP in TCI,TIA and LI group was(24.43±3.21),(15.51±2.65)and(13.52±5.45)mg/L respectively,and was significantly higher than that of healthy people (3.9±2.5)mg/L(P<0.01).The level of TpP was significantly higher in TCI group than that in TIA and LI group(P<0.01).The level of TpP was significantly higher in TIA group than that in LI group(P<0.01).The area under ROC curve for TpP to diagnose TCI was 0.979±0.013(P<0.01).The level of TpP on optimal cutoff was 19.1 mg/L.When the level of TpP was over 19.1 mg/L,TCI was determined with 95% sensitivity and 96%specificity, sum of which was largest of all.Conclusion The level of TpP can differentiate TCI from TIA and LI within 6 hours from onset.

Objective To observe the effect of complex sophorae injection combined with FOLFOX4 on Th17 cells, IL-17 and survival rate in patients with rectal cancer.Methods A total of 128 patients with rectal cancer were sellected in this study. The patients were divided into the control group (n=64) and observation group (n=64). The control group received the treatment of FOLFOX4 regimen, and the observation group received the treatment of FOLFOX4 regimen and sophorae injection. The Th17 cells were detected by flow cytometry, and IL-17 by ELISA assay.Results After treatment, the Th17 cells (11.28% ± 2.42%vs. 13.12% ± 3.15%,t=2.376) and IL-17 (16.58 ± 3.26 ng/mlvs. 21.84 ± 4.12 ng/ml,t=2.391) in observation group was lower than those in control group (P<0.05). After treatment, the effective rate (60.9%vs. 43.8%,χ2=2.384) and control rate (92.2%vs. 81.3%,χ2=2.371) in observation group was higher than that in control group (P<0.05). The different levels of white blood cells (37.5%vs. 60.9%,χ2=2.417), anemia (35.9%vs. 59.3%,χ2=2.421), thrombocytopenia (34.4%vs. 62.5%,χ2=2.432), nervous system toxicity (15.6%vs. 37.5%,χ2=2.458), gastrointestinal tract reaction (21.9%vs. 43.8%,χ2=2.453), oral mucositis incidence (28.1%vs. 57.8%,χ2=2.451) in observation group were lower than those in control group (P<0.05). The 1 year survival rate was 79.7% (51/64) in observation group,, which was higher than that of 60.9% (39/64) in control group (χ2=2.414,P<0.05).Conclusions The complex sophorae injection combined with FOLFOX4 regimen can reduce Th17 cells and IL-17 in patients with rectal cancer, improve survival rate, and reduce the clinical toxicity of chemotherapy drugs.

The discovery of cell-free fetal DNA ( cffDNA) in maternal plasma provides a new idea for noninvasive prenatal testing( NIPT).Though some studies to date have shown several fetal DNA markers, how to accurately distinguish cffDNA from the pool of maternal plasma free DNA is still a challenge.So far, NIPT based on cffDNA has been used for detection and study of a variety of diseases, along with the advance and development of technology, it will have a more broad application prospects.This article will make a review for the research status from the biological characteristics and the markers of cffDNA, the clinical applications and the existing issues and development prospects of NIPT based on cffDNA.

Objective To study the relationship between hyperferritinemia and early metabolism disturbance of sugar and Lipid.Methods 382 people in health examination from Hangzhou First People's Hospital were divided into hyperferritin group(A group)and hypoferritin group(B group)according to the level of ferritin.Blood fat,fasting blood glucose(FBG),uric acid(UA),hematoglobin(Hb),red blood cell count(RBC),hematocrit(HCT),mean corpuscular-hemoglobin concentration(MCHC)were determined,and adiposis hepatica was judged by ultrasonic inspection,then we analyzed by meams of statistics.Results The result showed that TG,LDL,HDL,ApoA1,ApoB,FBG,UA,Hb,RBC,HCT,MCHC had significant deviation between two groups.Ferritin was positive correlated with TG,TC,LDL,ApoB,Hb,RBC,HCT,and negative correlated with HDL,ApoA1.The incidence of adiposis hepatica in A group was obviously higher than B group.Conclusions Probably,ferritin was one of the markers of early metabolism disturbance of sugar and Lipid.

Objective To evaluate the significance and expression of the GDNF/GFRα1/RET genes in distal rectum with Congenital Anorectal Malformations(ARMs) Methods Specimens were collected from resected colon which is 3 cm away to the anus and the distal of rectum in 12 ARMs patients. Haematoxylin and Eosin (HE) staining, immunohistochemical (IHC) staining and reverse transcription PCR (RT-PCR) were used to test RET, GDNF and GFRα1 expression in the differ-ent site of samples with ARMs. Results Expression of ganglia and RET, GDNF and GFRα1 were all negative in distal rec-tum in 12 ARMs patients. Ganglionic cells were found in tissues 3 cm away from the anus where RET, GDNF and GFRα1 expression were also positive in those ARMs patients. Expression of RET, GDNF and GFRα1 were strong positive in middle and low imperforate anus indicated by brown color and week positive in high imperforate anus indicated by yellow color. One case of faeces contamination and one case of loose motion without anal incontinence were found in post-op follow up of high ARMs patients. By contrast, one case of rectal mucosa prolapse and one case of occasional faeces contamination which recov-ered with hip bath were found in post op follow up in middle or low ARMs. Conclusion The unsatisfactory anorectal func-tion is possibly related to the decrease or lost of neurotrophic factors (GDNF/GFRα1/RET) and ganglia in the myenteric plex-uses post plastic surgery in ARMs patients.

Epstein-Barr virus (EBV) remains one of the most important pathogens in children,which usually causes acute EBV infection,chronic active EBV infection,hemophagocytic lymphohistiocytosis,lymphoma and other cancers.Therefore,effective laboratory diagnosis is of importance in diagnosis,surveillance,and control of EBV-associated disease.Currently,a variety of detection methods have been applied in clinical laboratories and typical diagnostic assays are always focusing on EBV-DNA and serological tests.Different assays vary in different purposes and applications,which seems to be difficult to choose an appropriate technique.This article aims at systematically analyzing clinical significance of these assays and evaluating the immune functions of EBV infection and the detection of susceptibility genes of EBV-related disease.
