Objective: To establish the quality standard for Shangtongning capsules. Methods: Microscopic identification was used for the qualitative identification of Bombyx batryticatus, Scorpio, Eupolyphaga steleophada, Pheretima, Notoginseng radix et rhizo-ma and Gastrodiae rhizoma. A TLC method was used for the qualitative identification of Chuanxiong Rhizoma, Angelicae Sinensis Ra-dix, Notoginseng Radix ET Rhizoma, Dipsaci Radix and Glycyrrhizae Radix ET Rhizoma. HPLC was used to determine the content of liquiriti. The determination was performed on an Agilent TC C18 (250 mm × 4. 6 mm,5μm) column with the mobile phase consisting of acetonitrile-water(15:85)at the flow rate of 1. 0 ml·min-1. The detection wavelength was set at 276 nm. Results: The features of the microscopic identification were significantly visible. The TLC spots were clear and well-separated without any negative interference. The linear range of liquiriti was 0. 341-1. 193 μg (r=0. 999 9)with the average recovery of 98. 97%(RSD=0. 77%, n=6). Con-clusion:The method is simple, accurate and reproducible, which is effective in controlling the quality of Shangtongning capsules and provides the basis for improving the quality standard for Shangtongning capsules.

Objective To approach a way to induce MSCs to dopaminergic neuron by mesencephalic conditional media and cytokines in vitro,and supply an ideal cells source for the treatment of Parkinson's disease.Methods The rat MSCs were isolated primarily from the femurs and tibias of the Wistar rats.MSCs were cultured,proliferated and purified by passage culture.Cultuered MSCs were divided into the control and the experimental group.In control group,MSCs were cultured without any induction medium.MSCs of experimental group were first cultured at medium containing bFGF for 24 hours.Then media were replaced with induction media which contained the agents as follows,respectively:GM_1,GDNF, GDNF+GM_1,GDNF+GM_1+mesencephalic conditional media.The surface markers of the differentiated neuron,such as NSE and TH were detected by immunocytoehemistry after MSCs were cultured in induction media for 3 and 7 days.Results In control groups,the NSE expression of MSCs was very lower than experimental groups.The percentage of NSE-positive cells of GDNF+GM_1+mesencephalic conditional media group in 7 day((45.257?5.999)/HP)was significantly more than other groups(control group is 2.214?0.779,GM_1 group is 22.014?3.624,GDNF group is 31.345?2.850,GDNF?GM_1 group is 40.314?4.203,P

Objective To evaluate the application value of percutaneous transsplenic varices embolization(PTSVE)in the treatment of upper gastrointestinal hemorrhage in patients with schistosomiasis cirrhosis. Methods Sixteen schistosomiasis cir-rhosis patients(12 males and 4 females)with portal hypertension complicated with esophageal and upper gastrointestinal hemor-rhage were selected as the investigation subjects,all the patients had been treated by esophageal vein ligation and sclerothera-py,but with bleeding again post-operation. The patients were treated by PTSVE under the guidance of X-ray fluoroscopy. The success rate of PTSVE and the rate of complications were observed. In addition,the patients received PTSVE were reexamined with abdominal CT one month post-operation,and the degrees of varices were compared before and after PTSVE. Results Four-teen cases(87.50%)were successfully treated with PTSVE. Two cases(12.50%)failed,and one case had an abdominal bleed-ing 1 week post-operation. The abdominal CT showed the degrees of esophageal varices(P < 0.001),esophageal vein(P <0.001)and gastric varices(P < 0.001)were significantly decreased in the patients who received PTSVE one month after the op-eration. Conclusions PTSVE is a safe and effective method in the treatment of upper gastrointestinal hemorrhage in the pa-tients with schistosomiasis cirrhosis. PTSVE is especially suitable for the patients with severe liver cirrhosis,significantly bor-dered liver split,and bared main portal vein and even the branches.

Objective To discuss the application of the degree of portal systemic shunting in assessing the upper gastrointes-tinal bleeding in patients with hepatic schistosomiasis. Methods Thirty - three patients with upper gastrointestinal bleeding caused by hepatic schistosomiasis(a bleeding group)and 29 schistosomiasis cirrhosis patients without bleeding(a non-bleeding group)were enrolled as investigation subjects in Jinshan Hospital. The subjects were scanned by the 128 abdominal slice spiral CT. The portal systemic shunting vessels were reconstructed by using thin slab maximum intensity projection(TSMIP)and multi-planar reconstruction(MPR). The degrees of the shunting vessels of the subjects were evaluated and compared,and the relation-ship between upper gastrointestinal bleeding and the degree of the shunting was analyzed. Results In the bleeding group,the occurrence rates of the shunting vessels were found as follows:86.4% in left gastric varices,68.2% in short gastric varices, 50.0% in esophageal varices,50.0% in para-esophageal varices,37.9% in gastric varices,69.7% in gastric-renal varices, 51.5% in spleen-renal varices,25.8% in abdominal wall varices,15.2% in omentum varices,63.6% in para-splenic varices, 34.8% in umbilical varices,40.9% in retroperitoneal-paravertebral varices,and 36.4% in mesenteric varices. In the bleeding group,the occurrence rates and the degree of shunt were significantly higher than those in the non-bleeding group in esophageal varices,esophageal vein,left gastric vein and gastric varices(all P < 0.05). Conclusions CT portal vein reconstruction can accurately display the location,degree and walking of all kinds of shunting vessels. Esophageal varices,esophageal vein,left gastric vein and gastric varices can accurately predict the risk of upper gastrointestinal bleeding in patients with hepatic schisto-somiasis. The patents with higher degree of the shunting vessels have a higher risk of gastrointestinal bleeding.

OBJECTIVE:To observe the effects of total organic acid of Thladiantha dubia fruit(TOATF)on coagulation time and hemorheology of rats with cold coagulation and blood stasis. METHODS:60 rats were randomly divided in normal control group (water),model control group (water),aspirin group (positive drug,50 mg/kg) and TOATF low-dose,medium-dose and high-dose groups(50,100,200 mg/kg)with 10 rats in each group. Except for normal control group,cold coagulation and blood stasis model was induced by 4 ℃ water bath and subcutaneous injection of adrenaline hydrochloride,and then given correspon-dence medicine intragastrically,once a day,for consecutive 14 d. 24 h after last administration,blood samples were collected from aorta abdominalis. The coagulating time(CT),erythrocrit(HCT),plasma viscosity(PV),prothrombin time(PT),thrombin time (TT),activated partial thromboplastin time (APTT),platelet aggregation rate (PAR) and whole blood low-shear,middle-shear and high-shear viscosity were measured and blood sedimentation equation K value was calculated. RESULTS:Compared with nor-mal control group,CT,PT,TT and APTT of model control group were shortened,and HCT,PV,blood sedimentation equation K value,PAR and whole blood low-shear,middle-shear and high-shear viscosity increased(P<0.05 or P<0.01). Compared with model control group,CT,PT and APTT prolonged in aspirin group and TOATF medium-dose and high-dose groups,and PAR de-creased;PT of treatment groups prolonged,while HCT,PV,blood sedimentation equation K value and whole blood low-shear and middle-shear viscosity decreased(P<0.05 or P<0.01). CONCLUSIONS:TOATF has obvious improvement effects on anticoagula-tion and hemorheology in rats with cold coagulation and blood stasis.

Objective To evaluate the relationship between thyroid autoimmunity and the risk of preterm birth. Methods Literature search was done among PubMed, Embase, Wanfang Medical Database, China Academic Journal Network Publishing Database and China Biology Medicine disc from Jan. 1st 1980 to July 31st, 2015. (1) Literature were extracted according to inclusion and exclusion standards, and the quality of the extracted literature were evaluated by Newcastle-Ottawa Scale (NOS). (2) Meta-analysis was performed by RevMan 5 software formulated by using the Cochrane library databases. Various heterogeneity of the research was inspected firstly. According to the results of the inspection a certain effect model was selected (including fixed effects model, the random effects model) to be utilized in merger analysis. In this study pregnant women with both thyroid peroxidase antibodies (TPO-Ab) and thyroglobulin (TG-Ab) positive were defined as thyroid antibody positive pregnant women. Pregnant women with only TPO-Ab positive were defined as TPO-Ab positive pregnant women. Then the relationship of antibody positive and the risk of a pre-term birth was analyzed respectively. Results (1) Ten cohort studies were enrolled, of which NOS scale score were 7 or higher. All the studies are of medium quality and above. A total of 1 322 cases of preterm birth occurred among 19 910 pregnant women. (2) Positive thyroid autoantibodies did not increase the risk of preterm birth in euthyroid pregnant women (OR=1.41, 95%CI:0.83-2.40, P=0.200) or in pregnant women with hypothyroidism (OR=0.68, 95%CI: 0.32-1.44, P=0.310). Positive TPO-Ab in euthyroid pregnant women increase the risk of preterm birth significantly (OR=2.08, 95%CI:1.09-3.97, P=0.030), but positive TPO-Ab in pregnant women with hypothyroidism did not increase the risk of preterm birth significantly (OR=1.21, 95%CI:0.65-2.24, P=0.550). Conclusion Positive TPO-Ab is an independent risk factor of preterm birth in euthyroid pregnant women.

Objective To analyze the incidence and risk factors of microalbuminuria in newly diagnosed and hospitalized type 2 diabetes mellitus patients,and to provide the theoretical basis for therapy of diabetes and diabetic chronic complications.Methods The blood glucose,lipid profile,24h-urinaryalbumin,fasting and postprandial serum insulin and peptid C were measured in 286 newly diagnosed and hospitalized type 2 diabetic patients from Mar.2006 to Sep.2009.Microalbuminuria was defined as the 24h-urinary albumin between 30 to 300 mg twice.Insulin resistance index (HOMA-IR) was recorded and all the patients received fundus examination by ophthalmologists after expansion of the pupil to ensure whether there was retinopathy or not.Results (1)The incidence rate of microalbuminuria in this study was 19.58％ (56/286).(2)Normal albuminuria group and MA group combined DR were 19.57％ (45/230) and 33.93 ％ ( 19/56 ) respectively,and the difference was statistically significant( x2 =5.349,P =0.021 ).Compared with control,the FPG,HbA1c and HOMA-IR were significantly higher in microalbuminuria group ( FPG:[ 11.08 ± 1.76 ] mmol/L vs [9.24 ±1.65]mmol/L,t =-6.148,P ＜0.001;HbA1c:[11.54 ± 1.59]％ vs [9.39 ± 1.64]％,t =-7.533,P ＜0.001 ;HOMA-IR:[3.73 ±0.42] vs [3.50 ±0.30],t =-3.774,P ＜0.001 ).(3) Pearson correlation analysis revealed microalbuminuria was positively correlated with FPG( r =0.460),HbA1 c ( r =0.499),HOMA-IR( r =0.308)and combined DR(r =0.405)(P ＜0.01).(4)Stepwise multiple regression analysis revealed that FPG (ββ =- 0.804,P ＜ 0.01 ),HbA1 c (β =- 0.455,P ＜ 0.01 ) and combined DR (β =1.527,P ＜ 0.05 ) were independently risk factors of microalbuminuria.Conclusion The development of microalbuminuria in newly diagnosed and hospitalized type 2 diabetic patients is associated with FPG,HbA1c and HOMA-IR,and will be easier to merge diabetic retinopathy.

BACKGROUND:Compared with bone marrow transplantation, peripheral blood stem cel transplantation has its own advantages, including rich resources of stem cel s from the peripheral blood, convenient and easy col ection, without anesthesia, smal trauma, easily accepted, high safety, and easy to restore the patient’s hematopoietic system.
OBJECTIVE:To observe the function and safety of autologous peripheral blood mononuclear cel s in the treatment of patients with decompensated cirrhosis.
METHODS:Four patients with decompensated liver cirrhosis were selected from November 2010 to July 2011 in the First Affiliated Hospital of Dalian Medical University, aged 31-67 (averagely 44 years). Among them, three cases had hepatitis B, and another one had autoimmune liver disease. Peripheral blood stem cel s were col ected after being mobilized by granulocyte colony stimulating factor. Then, autologous peripheral blood stem cel s were transplanted via a hepatic artery catheter.
RESULTS AND CONCLUSION:There were no adverse reactions such as fever, bleeding and nausea after peripheral blood stem cel col ection and hepatic artery transplantation. Symptoms such as fatigue, poor appetite and abdominal distension gradual y improved at 1, 3 and 6 months after transplantation. Liver function and liver fibrosis indexes were improved to some extent after transplantation.
