ABSTRACT

OBJECTIVE Optimizing the water extraction technology of Xiangqin jiere granules. METHODS The orthogonal test of 3 factors and 3 levels was designed, and comprehensive scoring was conducted for the above indexes by using G1-entropy weight to obtain the optimized water extraction technology of Xiangqin jiere granules with water addition ratio, extraction time and extraction times as factors, using the contents of forsythoside A, baicalin, phillyrin, oroxylin A-7-O-β-D-glycoside, wogonoside, baicalein and wogonin, and extraction rate as evaluation indexes. BP neural network modeling was used to optimize the network model and water extraction process using the results of 9 groups of orthogonal tests as test and training data, the water addition multiple, decocting time and extraction times as input nodes, and the comprehensive score as output nodes. Then the two analysis methods were compared by verification test to find the best water extraction process parameters. RESULTS The water extraction technology optimized by the orthogonal test was 8-fold water, extracting 3 times, extracting for 1 h each time. Comprehensive score was 96.84 (RSD=0.90%). The optimal water extraction technology obtained by BP neural network modeling included 12-fold water, extracting 4 times, extracting for 0.5 h each time. The comprehensive score was 92.72 (RSD=0.77%), which was slightly lower than that of the orthogonal test. CONCLUSIONS The water extraction technology of Xiangqin jiere granules is optimized successfully in the study, which includes adding 8-fold water, extracting 3 times, and extracting for 1 hour each time.

ABSTRACT

Objective To compare the efficacy of Wang Juyi meridian regulating method for determining abnormal meridians versus syndrome differentiation-based acupoint selection in the textbook in treating stroke patients and analyze whether this method has an advantage in discriminating and treating stroke disorders. Method One hundred and thirty-eight stroke patients were allocated, in order of visits, to treatment and control groups. The therapeutic effects were evaluated after 20 treatments and compared at three months after treatment. The Stroke Specific Quality of Life (SS-QOL) scale score, meridian distribution state and correlation between syndrome type and meridian distribution were used as indicators. Result In the treatment group, the SS-QOL score had a statistically significant difference after treatment and at three months after that compared with before (both P<0.05), indicating that the quality of life improved in the treatment group of stroke patients. There was no statistically significant difference in the SS-QOL score after treatment (P>0.05) but there was at three months after treatment (P<0.05) between the two groups, indicating that after stroke the quality of life improved more in the treatment group than in the control group. In the stroke patients,meridian abnormality mainly occurred in hand and foot Taiyin, hand and foot Yangming, foot Jueyin and hand and foot Shaoyang meridians and seldom in hand and foot Taiyang, foot Shaoyin, Ren and Du meridians. There was a correlation between every syndrome type and a certain meridian. Conclusion Meridians have a specific distribution in stroke patients. There is a correlation between different syndrome type and the corresponding meridian. In stroke patients, Wang Juyi meridian regulating method can improve the quality of life in discriminating and treating stroke disorders.

ABSTRACT

cRGD-carboxymethyl chitosan-palmitic acid (cRGD-CMCh-PA) was synthesized and a pHsensitive paclitaxel-loaded cRGD-CMCh-PA micelles (PTX-cRGD-CMCh-PA) was prepared with the film dispersion method; related substances were characterized by FT-IR and 1H NMR. PTX-cRGD-CMCh-PA micelles were studied with the particle size distribution, zeta potential, morphology and release behavior in vitro was investigated by the method of equilibrium dialysis. In vitro cytotoxicity of different formulations on A549 cells was tested by MTT assay. The uptake process of micelles was explored using confocal microscopy and a live cell station was used to observe the dynamic phagocytosis. The subcutaneous and orthotropic tumor models were built to study the distribution of DiR-labeled micelles by near-infrared fluorescence (NIR) imaging system. The FT-IR spectra and 1H NMR spectra confirmed the successful conjugation of cRGD-CMCh-PA polymer and the degree of carboxymethyl and the palmitic acid grafted on chitosan were 45.0% and 15.0%. PTX-cRGD-CMCh-PA micelles were prepared with particle size of (162.9±1.5) nm, zeta potential of +26.3 mV and encapsulation efficiency and the drug loading of 99.67% and 28.5%, respectively. The micelles released slowly in pH 7.4 whose release curves were accorded with the Higuchi equation; they had an initial burst effect in second hours and showed a pH sensitive release behavior in pH 5.3. The IC50 of PXT-CMCh-PA and PTX-cRGD-CMCh-PA were 2.077 μg·mL-1 and 0.876 μg·mL-1, respectively. The cells uptake process of micelles in A549 cells revealed that the micelles were mainly co-located with lysosome and PTX-cRGD-CMCh-PA showed much better targeting effect. The NIR fluorescence imaging results showed that the micelles had a good targeting effect on both subcutaneous and orthotropic tumors. In this study, a novel copolymer cRGDCMCh-PA was synthesized with a sustained and pH-dependent drug release activity which would potentially become a new carrier for hydrophobic drugs.

<p><b>OBJECTIVE</b>To investigate the expression and possible roles of Wnt inhibitory factor-1 (Wif-1) and β-catenin in the Wnt pathway in childhood acute lymphoblastic leukemia (ALL).</p><p><b>METHODS</b>The clinical data of 35 children who had newly-diagnosed ALL and achieved complete remission on day 33 of remission induction therapy were retrospectively reviewed. The children before treatment were considered as the incipient group, and those who achieved complete remission on day 33 were considered as the remission group. Fifteen children with non-malignant hematologic diseases were enrolled as the control group. RT-PCR was used to measure the mRNA expression of Wif-1 and β-catenin. ELISA was used to measure the protein expression of Wif-1.</p><p><b>RESULTS</b>Compared with the control and remission groups, the incipient group had significantly lower mRNA and protein expression of Wif-1 and significantly higher mRNA expression of β-catenin (P<0.05). In the incipient and remission groups, high-risk children showed significantly higher mRNA expression of β-catenin and significantly lower mRNA and protein expression of Wif-1 than the medium- and low-risk children (P<0.05). In the incipient and remission group, the children with T-cell acute lymphoblastic leukemia showed significantly higher mRNA expression of β-catenin and significantly lower mRNA and protein expression of Wif-1 compared with those with B-lineage acute lymphoblastic leukemia (P<0.05). In each group, there was a negative correlation between the mRNA expression of Wif-1 and β-catenin (P<0.05).</p><p><b>CONCLUSIONS</b>Reduced expression of Wif-1 and increased expression of β-catenin may be involved in the pathogenesis of childhood ALL, and the degree of reduction in Wif-1 and/or increase in β-catenin may be related to prognosis.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the correlation between the lumbar bone marrow fat and abdominal fat.</p><p><b>METHODS</b>A total of 68 individuals (32 men and 36 women, aged 21-74 years with a median of 49.5 years) were included in this study. All the subjects underwent spectroscopic examination of the third lumber vertebra with the single voxel method on a 1.5T MR scanner to measure the fat fraction (FF%). Quantitative CT was also performed for measurement of the abdomen subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT). The measurements were compared between subjects aged ≥50 years and those below 50 years, respectively,in male or female subjects.</p><p><b>RESULTS</b>In male subjects, BMI, FF%, VAT or SAT showed no significant differences between the two age groups (P>0.05), and FF% was not correlated with BMI, VAT or SAT (r=0.109, 0.034, 0.066, respectively; P>0.05). In the female subjects, BMI, FF%, VAT and SAT differed significantly between the two age groups (P<0.05), and in ≥50 years group, FF% showed a positive correlation with VAT (r=0.499, P<0.05) but was not correlated with SAT (r=0.221, P>0.05); in<50 years group, FF% was not correlated with VAT or SAT (r=0.076, -0.067, respectively; P>0.05).</p><p><b>CONCLUSION</b>FF% is positively correlated with VAT in female subjects aged beyond 50 years, but is not correlated with VAT or SAT in male subjects or in younger female subjects.</p>
