"Resolving,espulsing and tonifying" three methods are the general outline of endotherapy in surgery of TCM.The author of this article thinks that pelvic inflammation and appendagitis can be classified in internal ulcer and vusceral carbuncle,and it can be treated by "Resolving,espulsing and tonifying" three methods.As the general programme of treating female inflammatory aphoria in different periods,the three methods can avoid exfetatio and promote the probability of pregnancy.Resolving method is applied in acute period of inflammatory aphoria,active period of chronic inflammatory and chronic pelvic inflammation when abdominal mass has formed but vital qi is not deficient.The pathologic character in this period is sufficiency of vital qi and excessive of pathogenic qi.Expulsing method is applied in inflammatory aphoria patients whose pathogenic has not been cleared but the vital qi has been harmed,at this time damp heat pathogen poison remain in uterus meridians and the nvital qi has no power to resist pathogen,and whose corporeity is always week and infects pathogen poison which results in the course of diseases being repeated and prolonged.Tonifying method is applied after the resolving and espulsing methods have been used.In this period,damp heat stasis have been cleared,inflammation and inflammatory matters have been absorbed,disease has been improved and patient has had condition to be pregnant.Tonifying method can promote human generative function and improve the possibility of conception.

The precocious puberty in female rats were induced by subcutaneous injection of N-methyl-DL-aspartate (NMA). The female rats with induced precocious puberty showed the same sexual feature as the rats that had normal puberty. NMA plays its role at the level of hypothalamus. Subcutaneous injection of NMA is an effective means to induce true precocious puberty in female rats.

Object To study the causes for the occurrence of red skin and dark green skin of Panax quinquefolius L. during processing and its mechanism. Methods To observe the phenomena and analyze the result which simulated the processing condition of P. quinquefolius based on its components. Results The cross section of P. quinquefolius began to appear light red at 40 ℃, lasting 72 h. Whereas the time of browning was shortened with the temperature rising. The cross section of P. quinquefolius turned green while dipping in solution of Fe 3+ ion of 0 01 mol/L for 25 min. The time of turning green was shortened with the increasing concentration of Fe 2+ , Fe 3+ solution. Conclusion The results show that red skin of P. quinquefolius was caused by the Maillard reaction while drying at the excessive higher temperature. Whereas the complex reaction between phenolic substances in P. quinquefolius and metal ions during processing might result in dark green skin of P. quinquefolius. This expounds the mechanism of red skin and dark green skin turning during the P. quinquefolius processing in the theory.

Objective:? N oxalo L ?,? diaminopropionic acid were isolated from the powder of red ginseng. its physiological characteristics were studied. Method:This material is obtained by CM Sephadex C 25 and FPLC MonoQ. We have examined the effect of ? N oxalo L ?,? diaminopropionic acid on contraction of artery of guinea pig. Result:When histamin and adrenalin do not exist, there is neither contraction nor relaxation. It can strengthen induction of contraction of artery of guinea pig, but it has no such effect on adrenalin. Besides, it doesn't induce plaque coagulation through adrenalin, ADP blood coagulation enzyme and collagen. It doesn't suppress the transformation from tension peptide of blood vessel to enzyme.Conclusion:Hemostatic effect of ? N oxalo L ?,? dlaminopropinomie acid may caused by vesseles contraction through promoting Histamine.

OBJECTIVETo obtain 20(S)-ginsenoside Rh1 by the method of enzymolysis with the protopananxtriol saponins, and to provide the theory for large-scale preparation of 20(S)-ginsenoside Rh1.

METHODAB-8 macroporous resin was used to isolate the total saponins of the stems and leaves from Panax ginseng and the protopanaxtriol saponins (mainly included Rg1 and Re) were obtained. Then, we used enzymic hydrolysis (helicase) with the protopanaxtriol saponins to get the secondary ginsenoside 20(S)-Rh1. High performance liquid chromatography analysis method was established to determine the conversion with the YMC C18 column at the 25 degrees C.

Objectives To provide prenatal diagnosis and genetic counseling for four athigh-risk pregnant women with a suspected family or personal history of fragile X syndrome (FXS) by genetic screening of fragile X mental retardation (FMR1) gene.Methods This study was conducted on four pregnant women (No.l to 4) who received outpatient treatment in Peking University First Hospital from August 2014 to June 2016.Genomic DNA was extracted from peripheral blood samples of the pregnant women and six of their family members,four of which were suspected or confirmed FXS and the other two were FMR1 gene carriers.Amplide X kits were used to detect CGG repeat size in FMR1 gene.Two amniocytes and one chorionic villi samples were collected from three pregnant women to extract DNAs for FMR1 gene and karyotyping analyses.Results There were patients diagnosed with FXS in all the families by detecting CGG repeat numbers in FMR1 gene.The pregnant woman No.1 was a permutation carrier;No.2 carried normal FMR1 alleles while her brother had a mutation with over 20 CGG repeats in FMRI gene at chromosome X.No.3 and 4 were full mutation carriers with over 200 CGG repeats in FMR1 gene.After genetic counseling,No.3 decided to terminate the pregnancy due to abnormal fetal karyotype (47,XY,+21) and full mutation of FMR1 alleles.No.1 and 4 continued to pregnancy as their fetuses were normal in FMR1 alleles and karyotype.No.2 continued to pregnancy as her fetus was free of FXS risk.Conclusions Prenatal diagnosis and genetic counseling should be conducted on women at highrisk for FXS to avoid birth defects.People with a family history of FXS should be tested for FMR1 gene carrier status.

Objective Sarcopenia and metabolic syndrome share similar pathophysiological mechanisms. The aim of this study was to investigate the prevalence of sarcopenia among health examination population, and to analyze the relationship between sar-copenia and blood pressure, blood glucose, uric acid and lipids. Methods Physical examination data of 1191 healthy persons in the medical examination center of the hospital from Mar 2011 to Jun 2011 were collected. The weight, skeletal muscle, body fat, body mass index ( BMI) , waist circumference,body fat percentage, waist-hip ratio and visceral fat area were analyzed by human body compositionanalyzer and the prevalence of sarcopenia was observed. At the same time, triglyceride (TG), total cholesterol (TC), high density lipo-protein-cholesterol ( HDL-C ) , low density lipoprotein-cholesterol ( LDL-C) , uric acid and fasting blood glucose were also detected. Results The prevalence rate of sarcopenia of the subjects was 5.21%, and the highest incidence was found in ≥60 years group( 11.11%) . The prevalence rates of overweight and obesity were 33.8% and 10.2%, respectively. The prevalence of sarcopenia is grad-ually higher along with increasing BMI. The prevalence rates of sarcopenia of overweight and obesity subjects were 5.47% and 26.23%, respectively. Compared with the normal control group, the level of weight[(66.34±11.75)kg vs (76.71±12.84)kg ], BMI[(23.37± 3.13) vs (28.05±3.66)], body fat percentage[(25.33±6.06)% vs (36.76±4.47)%], waist circumference[(83.19±9.56)cm vs (95.45±13.74)cm] and visceral fat area[(88.96±29.74)cm2 vs (136.91±25.56)cm2] were higher in the sarcopenia group (P<0.05). Compared with the normal control group, the incidence of systolic blood pressure[(125.59±30.04)mmHg vs (139.39±19.79) mmHg], diastolic blood pressure[(75.82±11.95)mmHg vs (82.34±10.96)mmHg ] TG[(1.56±1.12)mmol/L vs (1.98±1.72)mmol/L] and uric acid[(313.75±83.07)mmol/L vs (335.55±96.07)mmol/L] were higher in the sarcopenia group (P<0.05). Compared with the normal subjects, the detectable rates of abnormal diastolic blood pressure, fasting blood glucose, uric acid, and LDL-C were increased in the sarcopenia, obesity and sarcopenia combined with obesity subjects (P<0.05). The odds ratio of abnormal systolic blood pressure, diastolic blood pressure, uric acid, and LDL-C increased in the sarcopenia, obesity and sarcopenia combined with obe-sity subjects using logistic regression analyses after correction of gender and age. Conclusion The sarcopenia may have some con-nection with metabolic risk factors. Early detection of sarcopenia can help to distinguish people predisposed to metabolic syndrome, and it has important significance for prevention of chronic disease.

Objective To perform a prenatal diagnosis for the second fetuses from 28 pedigrees with proband of mitochondrial disease due to mitochondrial DNA (mtDNA) mutation.Methods From April 2011 to November 2015,peripheral blood samples of 28 probands and their parents,urine samples of these probands and their mothers as well as amniotic fluid samples of the second fetuses from the 28 pedigrees were collected in Peking University First Hospital.DNA sequencing was used to identify mtDNA mutations.Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was performed to verify mutation sites,calculate mutation loads,and further confirm the diagnosis after birth.Microsatellite maker analysis was also performed on five short tandem repeats located in nuclear genes to exclude maternal contamination.Statistical analysis was carried out using independent t-test.Results In the 15 pedigrees carrying A3243G mutation,13 mothers and nine fetuses carried A3243G mutation.Neither the other two mothers nor their fetuses were positive for A3243G mutation.Among the 12 pedigrees with T8993G mutation,there were eight mothers carrying T8993G mutation and all of their fetuses carried the same mutation;and the other four mothers and their fetuses were negative for T8993G mutation.T10191C mutation was only found in one proband and the second fetus of that pedigree,but not in the mother.None of the fathers had mtDNA mutation.Results of PCR-RFLP were consistent with those of DNA sequencing.Short tandem repeat analysis demonstrated that amniocyte samples were from fetuses without maternal contamination.No mtDNA mutations were found in the six newborns who were negative for mtDNA mutations in prenatal diagnosis.The mean mutation load in urine samples of the six mothers without A3243G mutation in amniocytes was significantly lower than that of the nine mothers with A3243G mutation [(10.1 ±4.8) ％ vs (28.2 ± 15.1) ％,t=2.290,P=0.043].Conclusions The lower the mtDNA mutation load in maternal urine samples,the less the possibility she bears a child with mtDNA mutation.However,prenatal diagnosis of mitochondrial disease is necessary.

Objective:To investigate the clinical value of Omniview combined with volume contrast imaging (VCI) in measuring the posterior angle of fetal near-field lateral ventricle.Methods:Fifty fetuses whose lateral ventricles were widened, corpus callosum was poorly developed, and who had hydrocephalus as indicated by routine ultrasonography performed between October 1, 2018 and December 31, 2019 in Hangzhou Obstetrics & Gynecology Hospital were included in this study. The width of the posterior angle of fetal near-field lateral ventricle was measured using routine ultrasonography, Omniview-VCI technique, and magnetic resonance imaging (MRI) in each fetus and compared among the three techniques.Results:The width of the posterior angle of fetal near-field lateral ventricle measured by Omniview-VCI and MRI techniques was (1.17 ± 0.15) cm and (1.20 ± 0.12) cm, respectively, which was significantly greater than that measured by routine ultrasonography [(1.11 ± 0.13) cm, t = 2.137, 3.597, both P < 0.05]. There was no significant difference in the width of the posterior angle of fetal near-field lateral ventricle measured by Omniview-VCI technique versus MRI technique ( t = 1.104, P > 0.05). The mean examination cost and waiting time of Omniview-VCI technique were (222.15 ± 3.20) yuan and (0.24 ± 0.04) days, which were less or shorter than those of MRI technique [(597.23 ± 11.02) yuan, (1.02 ± 0.10) days, t = 213.126, 51.210, both P < 0.05]. Conclusion:Omniview-VCI technique can replace MRI and accurately measure the posterior angle of fetal near-field lateral ventricle. It provides a more simple, fast and effective method for evaluating fetal near-field lateral ventricle, and can become a conventional application technique.
