1.Clinical observation of the application of disposable suction curettage tube in the early intrauterine pregnancy
Chinese Journal of Primary Medicine and Pharmacy 2011;18(1):29-30
Objective To find the best way to terminate early intrauterine pregnancy through comparative observation. Methods Through comparing the method of using disposable suction curettage tube to terminate early intrauterine pregnancy and medical abortion, and the method of induced abortion with traditional metal suction tube combined with local infiltration anesthesia, the complete abortion rate, intraoperative pain, blood loss and complications,etc were observed. Results Using disposable suction curettage tube to terminate early intrauterine pregnancy can result in no pain or less pain,with a bleeding time 1 to 6 days ,3.5 days on average ,both of which less than menstrual volume,with 100% complete abortion and no complications. Postoperative recovery time of period was 25 to 40 days,32.8 days on average. This method was better than medical abortion and induced abortion with local infiltration anesthesia. Conclusion Using disposable suction curettage tube to terminate early intrauterine pregnanncy did not need cervical dilation,and had advantage of light suction,less bleeding,no pain or less pain for pregnant women,no complications,rapid recovery,and was easy and safe to operate. It was the best way to terminate early intrauterine pregnancy.

Traditional Chinese Drug Research & Clinical Pharmacology 2000;0(06):-
Objective To compare the rutin contents in 7 kinds of commercial Fructus jujubae by HPLC method. Methods The analysis was carried on MN NUCLEODUR C18 column. The mobile phase consisted of acetonitrile-0.05 % H3PO4(15 ∶ 85), flow rate was 1.0 mL/min, determination wavelength was 257 nm and the column temperature was at 40 ℃ . Results The linear range was 0.050 5~ 0.404 4 ? g and r= 0.998 7.The recovery was 96.2 % and RSD 1.6 % (n=6). Conclusion This method can eliminate the interference of sugar ingredients efficiently and is with good repeatability. It is suggested that the plumper the fruits of jujubae, the higher the content of rutin.

OBJECTIVE:To establish a method to determinate the content of paeoniflorin in Bailing tablet,and to evaluate the uncertainty of results. METHODS:HPLC was performed on the column of Platisil C18 with mobile phase of water- acetonitrile(87:13,V/V) at a flow rate of 1 ml/min,the detection wavelength was 230 nm,the column temperature was 25 ℃ and the injection volume was 10 μl. Quantitative analysis was conducted for the processes and procedures and the uncertainty was evaluated. RESULTS:The linear range of paeoniflorin was 0.100 1-2.502 8 μg;RSDs of precision,stability and reproducibility tests were lower than 2.0%,recovery rate was 98.7%-100.9%(RSD=0.86%,n=6). Reference substance amount,elution produce and the accuracy of method had great effect on the uncertainty. CONCLUSIONS:The established method can be used for the content determination of paeoniflorin in Bailing tablet,and the uncertainty evaluation provides reliability for the method.

It is important to establish a simple method of culture in vitro to obtain purity oligodendrocyte. This paper introduced the re-searches about co-culture in vitro with rat cortical gliocyte, proliferation and differentiation of oligodendrocyte progenitor, differentiation of oligodendrocyte and identification of cell surface antigens at different stages of development.

Objective To make a qualitative and a quantitative control on the Calculus Bovis in Houzao Niuhuang Powder.Methods Hyodeoxycholic acid and bilirubin in Calculus Bovis were separately identified by TLC,and the cholic acid content was determined by TLCS with the scan wavelength of ?s=380 nm,?R=650 nm.Results TLC can be used for the identification in-vitro cultured Calculus Bovis and artificial Calulus Bovis,the samples containing cultured Calulus Bovis showed the specific spots of bilirubin but no hyodeoxycholic acid spot while the samples containing artifical Calulus Bovis showed the hyodeoxycholic acid spot but no bilirubin spot.TLC-scanning can be used to measure the quantity of cholic acid,with the linear range being 0.2~1.8 ?g,average recovery rate of 99.5 %,and RSD being 3.3 %(n=6),and the results accorded with the criterion of the cultured Calculus Bovis in Chinese pharmacopoeia.Conclusion The methods can effectively control the quality of Calculus Bovis in Houzao Niuhuang Powder.

ObjectiveTo elucidate the association between aquaporins (AQPs) expression in kidney tissue and edema of nephrotic syndrome(NS) patients.MethodsNS patients were divided into edema group (14 cases) and non-edema group (8 cases).Ten patients without NS were used as control group.Expressions of AQP1,AQP2,and AQP4 in renal tissues of 3 groups were detectedbyimmunohistochemistrywithstandardtechniquesandsemi-quantitativeanalysis.Association between AQPs expression and edema was examined.ResultsThe positive index of AQP1 expression in proximal tubules in edema group was 0.0373±0.0110,which was significantly lower as compared to non-edema group (0.0510±0.0120) and control group 0.0574±0.0100),while the difference between non-edema and control groups was not significant.The positive index of AQP1 expression in glomerulus was 0.0106±0.0037 in edema group,which was significantly higher than that in non-edema group(0.0021±0.0013) and control group(0.0020±0.0012),while no significant difference was found between the last two groups.AQP2 mainly localized in the collecting duct system.The positive indexes of AQP2 expression were 0.0498±0.0081,0.0370± 0.0072 and 0.0255±0.0103 in edema group,non-edema group and control group,respectively.The differences were significant among 3 groups.AQP4 expression was not found in the renal cortex and collecting duct system.ConclusionsAQPs expression is different in renal tissues of NS patients.AQP2 may play an important role in the edema of NS patients,and AQP1 may involve in the occurrence of edema.

Purpose:The value of color doppler ultrasonography( CDUS) in monitoring hemodynamic changes was investigated in patients with hyperdynamic circulatory state before and during 730 days after orthotopic liver transplantation.Materials and Methods:83 cases of orthotopic liver transplantation (OLT) were examined by CDUS to assess the hemodynamic changes of portal vein,hepatic artery,splenic artery and longitudinal diameter of the spleen ( LDS).Results:(1) Portal flow velocity ( PFV) was significantly lower in pre-OLT but higher than controls (P < 0.05 ) during 730 days after OLT.Resistance index of the hepatic artery ( HARI) in pre-OLT and within 7 days- after OLT was significantly higher (P<0.05).(2) Resistance index of splenic artery ( SARI) was also significantly higher in pre-OLT (P < 0.05 ).LDS was significantly higher after OLT than in both pre-OLT phase and controls(P<0.05).Conclusions: In early stage after OLT,HARI changed from high to low value and so did PFV,which kept the stability of hepatic blood flow.In late stage,high PFV and large spleen improved,but could not back to normal.

Objective To discuss the preventive measures of anterior palatal fistula by modified the operation of cleft palate. Methods For 23 patients of complete cleft palate with alveolar ridge cleft, bilateral mucoperiosteum flap was moved forward as possible so as to close fistula front of hard palate, and incised junction of the hard and soft palate to prolong soft palate and the wound was repaired by buccal mucosal flap.The incidence of anterior palatal fistula and velopharyngeal closure after operation was observed. Results Twenty-three patients were rechecked 1 month after operation ,there was no anterior palatal fistula occurring,10 cases were examined by epipharyngoscope 1 year after operation,the velopharyngeal closure was 90%-100%. Six cases were followed up for 6 months,the velopharyngeal closure was 80%-85%. Conclusions For second-stage operation methods of anterior palatal fistula, there are too many discussions of selection criterias, advantages and disadvantages. If first-stage operation is taken measures to prevent anterior palatal fistula or decrease the diameter of fistula as possible. It reduces percentage of second-stage operation or decreases the difficulty. It should get more attention in the clinical works.
