OBJECTIVETo analyse the effect of the reduction of multiple pregnancy through transvaginal ultrasonic monitoring on the pregnancy outcome.

METHODSEighty-four cases were divided into two groups according to whether they had vaginal hemorrhage before operation. And the pregnancy outcomes were analyzed.

RESULTSThe abortion rate and preterm birth rate of the vaginal hemorrhage group were higher, and the difference was statistically significant.

CONCLUSIONSThe reduction of multiple pregnancy through transvaginal ultrasonic monitoring is a safe operative method. But it is only a remedial treatment for multiple pregnancy, and how to prevent multiple pregnancy is of more practical value.

Patients with early cataract may have normal visual acuity ( VA ) but complain that they have problems in driving at night, like seeing things through a veil. This phenomenon is defined as disability glare which maybe caused by growing stray light. Patients with intraocular lens following cataract surgery may complain about glare, halos and shadows in visual field, which are also resulted from dysphotopia. Disability glare is the VA loss due to disturbing luminance in visual field. ln other words, it's the retinal contrast sensitivity reduction because of the straylight. This article contains the consensus and new progress of disability glare. lt provides solutions according to its effect factors and offers clues for further study.

LRP16 is a novel gene which was found in our laboratory by using methylation-sensitive restriction landmark genomic scanning (RLGS) technique. In order to clone the full-length cDNA of this leukemia relapse associated gene, the method of rapid amplification of cDNA end (RACE) was employed. By optimizing some procedures of RACE method, the 5'- and 3'-untranslated region of LRP16 cDNA was successfully sequenced. Then, the full length of LRP16 cDNA and open reading frame (ORF) was constructed and was registered in GenBank. The above-mentioned procedure demonstrated RACE technique is a rapid and sensitive method for cloning unknown gene. Especially, it is very useful to cloning the 5'- and 3'-untranslated region of a novel gene.

OBJECTIVETo establish the quantitative methods for calycosin glycoside and formononetin in Radix Astragali, and the samples from different sources were analyzed, in order to supply the basis for the quality control of Radix Astragali.

METHODThe content of calycosin glycoside and formononetin in 59 samples of Radix Astragali from eight with different provinces was analyzed by HPLC-DAD.

RESULTThe contents of calycosin glycoside and formononetin in Radix Astragali from different sources, with different cultivating method or in different ages differed markedly, and the results showed that the quality of samples from Shannxi, Innermongolia and Shanxi were better than other sources, and the semi-wild samples were better than other cultiving samples, moreover the shorter age, the better quality.

CONCLUSIONThis simple, accurate and reproducible method could use to determine the contents of isoflavanoids in Radix Astragali.

Objective To analyze the forensic characteristics of 24 psychiatric patients who died of long-term use of psychotropic drugs.Methods Cases of sudden death of psychiatric patients from2011 to 2016 were collected.The forensic characteristics of these sudden deaths were retrospectively analyzed by systematic investigation plus results of autopsy and toxics (drugs).Results Among the 24psychiatric patients who died of long-term use of psychotropic substances, the ratio of male to female was 1.7∶1, and the average age was (59.0±8.8) years.Fifteen patients had clear disease durations (14.4±8.2) years, and other the nine were known to have disease durations of over 3 years.The death time of 62.5％of patients was the daytime in working days, and 91.7％of the patients died at home.Most patients complained different degrees of physical discomfort before death.Patients with schizophrenia (20 cases) were the most common, followed by depression (4 cases).All patients had the history of taking psychotropic drugs, with clozapine and chlorpromazine being the mostly detected ones.The causes of death were mainly circulatory diseases (15 cases), with the most common being myocarditis (11 cases) followed by pneumonia (4 cases).Conclusion Critical attention should be paid to the risk of antipsychotics-induced sudden unexpected deaths for psychiatric patients, particularly for those with schizophrenia.

Chloride channels belong to a superfamily of ion channels that permit passive passage of anions, mainly chloride, across cell membrane. They play a variety of important physiological roles in regulation of cytosolic pH, cell volume homeostasis, organic solute transport, cell migration, cell proliferation, and differentiation. However, little is known about the functional regulation of these channels. In this study, we generated an integrated transgenic worm strain expressing green fluorescence protein (GFP) fused CLC-type chloride channel 1 (CLH-1::GFP), a voltage-gated chloride channel in Caenorhabditis elegans (C. elegans). CLH-1::GFP was expressed in some unidentified head neurons and posterior intestinal cells of C. elegans. Interacting proteins of CLH-1::GFP were purified by GFP-Trap, a novel system for efficient isolation of GFP fusion proteins and their interacting factors. Mass spectrometry (MS) analysis revealed that a total of 27 high probability interacting proteins were co-trapped with CLHp-1::GFP. Biochemical evidence showed that eukaryotic translation elongation factor 1 (EEF-1), one of these co-trapped proteins identified by MS, physically interacted with CLH-1, in consistent with GFP-Trap experiments. Further immunostaining data revealed that the protein level of CLH-1 was significantly increased upon co-expression with EEF-1. These results suggest that the combination of GFP-Trap purification with MS is an excellent tool to identify novel interacting proteins of voltage-gated chloride channels in C. elegans. Our data also show that EEF-1 is a regulator of voltage-gated chloride channel CLH-1.

OBJECTIVETo investigate the relationship of (TAAAA)n repeat polymorphism in the promoter of the sex hormone-binding globulin (SHBG) gene and SHBG serum levels to the glucose metabolic status of Chinese polycystic ovary syndrome (PCOS) patients in Shandong province.

METHODSGeneScan method was used to detect and identify (TAAAA)n repeat number (alleles) and genotypes for 156 controls and 157 patients who were divided into normal glucose tolerance without hyperinsulinemia (NIR group) and with hyperinsulinemia (HI group) and abnormal glucose metabolic (AGM) group according to the results of oral glucose test and insulin resistant test; IRMA was used to measure serum SHBG for part of them.

RESULTSFive alleles containing (TAAAA) 6-10 repeats and 14 genotypes including 6/6, 6/7, 6/8, 6/9, 6/10, 7/7, 7/8, 7/9, 7/10, 8/8, 8/9, 8/10, 9/9, 9/10 repeats genotypes were present in the subjects. Genotype distribution of 6/10 repeats genotype is lower in PCOS than that in control, and 8/9 repeats genotype vice versa (P < 0.01); among PCOS subgroups, the eight repeat genotypes in NIR group is more frequent than that in HI group (P < 0.01), and 7/9 genotype distribution in AGM group is higher than that in NIR group and HI group(P < 0.05-0.01). The serum SHBG levels in homozygous genotype groups exhibit a sequence of 8/8 > 9/9 > 6/6, 7/7 repeats and the fall of serum SHBG trend is in reversed relation with the increase in body mass index (BMI), Homa-IR, and blood pressure. Serum SHBG levels in AGM exhibit a sequence of HI group < NIR group < control but show no statistical difference between both groups.

CONCLUSIONThis study reveals that the repeat number, alleles, genotypes and their distributions in Chinese women are very different from these in foreigners. Some special genotypes and low serum SHBG levels may be associated with PCOS and its glucose metabolic status; some special genotypes may influence Chinese serum SHBG and need more studies, but both SHBG gene polymorphism genotype and serum SHBG are not good indicators to find out the PCOS individual at high risk.
