Objective: To sieve the bioactive constituents of Radix Puerariae,serum pharmacochemistry research was performed.Method: Based on the establishment of HPLC fingerprints of Radix Puerariae,the constituents absorbed into blood were determined by comparing the HPLC fingerprints of the methanol extracts,tested serum samples and blank serum sample.Results: Four compounds absorbed into blood were detected,among which two were original constituents of Radix Puerariae(including puerarin),the other might be metabolites of the original constituents.Conclusion: These four constituents absorbed into blood were possible bioactive components of Radix Puerariae.Further studies on them will help clarify the bioactive constituents and mechanisms of Radix Puerariae.

OBJECTIVETo observe the effect of magnesium sulfate, Nifedipine Tablet (NT) combined Salvia Injection (SI) on endothelin-1 (ET-1), nitric oxide (NO), thromboxane A2(TXA2), prostacyclin I2(PG2), and hemorheology of preeclampsia patients.

METHODSTotally 704 preeclampsia patients were randomly assigned to the treatment group and the control group, 352 cases in each group. All patients were treated with magnesium sulfate combined NT (on the first day: slow intravenous injection of magnesium sulfate 5 g + intravenous dripping of magnesium sulfate injection 10 g + oral administration of NT 30 mg; on the second and third day, intravenous dripping of magnesium sulfate injection 10 g + oral administration of NT 30 mg), while those in the treatment group were dripped with SI additionally at 20 mL per day for 3 consecutive days. Before and after treatment plasma levels of endothelin-1 (ET-1), nitric oxide (NO), TXA2, PGi2, and hemorheology indicators [such as high blood viscosity (HBV), low blood viscosity (LBV), plasma viscosity (PV), erythrocyte rigidity index (ERI), fibrinogen (FIB)] of two groups were detected.

RESULTSCompared with the same group before treatment, serum levels of ET-1, TXA2, HBV, LBV, PV, ERI, and FIB decreased in the two groups after treatment (P <0. 05), but levels of NO and PG2 increased (P <0. 05). Compared with the control group in the same period, levels of ET-1, TXA2, HBV, LBV, PV, ERI, and FIB decreased in the treatment group after treatment (P <0. 05), but levels of NO and PGI2 increased (P <0. 05).

CONCLUSIONMagnesium sulfate, NT combined SI could effectively regulate the balance of ET-1/NO and TXA2/PGI2, and improve hemorheology of preeclampsia patients.

Cytometric bead array (CBA) is a new analytical technique, which can achieve real-time and rapid detection of targeted components in a small amount of sample. With many advantages of high throughput screening, high specificity and sensitivity, low cost, easy operation and good repeatability, this CBA technique has been widely used for the detection of various components in foods, agricultural products and environmental samples. Recently, it has got significant development in rapid detection of small molecules. This review briefly introduced the theory of CBA technique, summarized the application in the analysis of small molecules, such as mycotoxins, pesticide residues, shellfish toxins, and then prospected the application of trace small molecules detection in the complex matrices of traditional Chinese medicine and the development trend of it.

It is a trend that innovate the traditional bilingual education model and select a new teaching model.Code-switching is a lingual phenomenon when a passages or articles are expressed with two or more language.To guarantee effect of bilingual education and improve education quality,penetration bilingual education was applied during microbiology teaching.Professional English vocabulary,words,passages or articles were introduced to students timely and by measure by the way of language code-switching.The results showed that bilingual teaching mode with language code-switching inspire study emotion and self-confidence of English expression from students.

Background It is well known that sclera remodeling occurs during axial elongation in myopia under the control of growth hormone or its downstream effectors.The role of transforming growth factor-β (TGF-β) in myopia has been determined in previous studies.Bone morphogenetic protein (BMP) is one of members of the TGF-β superfamily,but if it plays an important role in the genesis and development of myopia is not completely clear.Objective This study was to identify the presence of BMPs in normal guinea pigs sclera and investigate the change of BMPs in the sclera in form-deprivation myopia (FDM) of guinea pigs.Methods Thirty young guinea pigs were randomized into normal control group and experimental group using table of random number.FDM models were established by occluding unilateral eyes of guinea pigs with a translucent lens for 14 days in the experimental group,and the fellow eyes served as the controls.Diopter of all eyes was tested by retinoscopy optometry,and ocular axial length was measured by A-sonography before and after modeling.Posterior sclera tissue of the animals was obtained on 14 days,and the relative expression level of BMPs mRNA and protein were assayed by reverse transcription PCR (RT-PCR) and Western blot.The use and care of the animals complied with ARVO Statement.Results On 14 days after occluding of unilateral eyes,the refraction diopter of the experimental group was (-0.48±0.51) D,and that of the fellow eyes was (3.22 ±0.34) D,showing a significant difference between them (t =-12.814,P =0.000).Also,a significant difference in the diopter was seen between the experimental group and normal control group ([-0.48±0.51]D vs.[2.97±0.70]D,t =-11.878,P=0.000).Axial length was (8.30 ± 0.05) mm in the experimental group,(8.11 ±0.06) mm in the fellow eyes and (8.06±0.06) mm in the normal control group,showing a significant increase in the experimental group compared with the fellow eyes and normal control group (t =7.230,P =0.000 ; t =9.084,P=0.000).The expressions of BMP-2 mRNA,BMP-4 mRNA,BMP-5 mRNA in posterior sclera were detected in the normal guinea pigs.Fourteen days after the induction of myopia,the relative levels of BMP-2 mRNA and BMP-5 mRNA in sclera were 0.41 ± 0.11 and 0.65 ± 0.06 in the experimental eyes,which were significantly lower than 0.62 ± 0.07 and 0.84 ± 0.03 in the fellow eyes with the descent range of 34.48％ and 23.67％ respectively (t=2.838,P=0.017; t=2.524,P=0.028).The relative values of BMP-2 protein and BMP-5 protein were 0.44±0.06 and 0.70±0.05 in the experimental eyes,and those of the fellow eyes were 0.61±0.05 and 0.82±0.03,showing significant decline in the experimental eyes with the lowing range of 23.42％ and 15.21％,respectively (t =2.465,P =0.030;t =2.445,P=0.031).No significant differences were found in the expression of BMP-4 mRNA and protein in posterior sclera between the experimental eyes and the normal control eyes (mRNA:t =0.704,P=0.460;protein:t=0.987,P=0.365).Conclusions The expressions of the BMP-2 and BMP-5 in sclera down-regulate significantly in FDM eyes,which suggest that BMP-2 and BMP-5 participate in sclera remodeling during myopia induction.

Objective To analyze the safety and diagnostic value of ultrasound-guided biopsy with simple biopsy clip in children.Methods Under simple biopsy clip 52 cases were performed percutaneous renal biopsy.Then the curative rate and the incidence rate of complications were evaluated.Results Of 52 cases,49 cases(94.23%) gained enough renal tissue specimen for histological evaluation;Three failed cases occurred at early stage,nothing was found at later stage.The main complication was macroscopic hematuria occurred only once or twice after the operation and perirenal hematoma in 1.92% of the cases.No other severe complications were found.Conclusions The biopsy clip is convenient and sterile,and can guide the biopsy device exactly and safely.The use of 18-gauge biopsy gun and the automated biopsy device in children can decrease the complication rate,which can be easily performed.
