Objective To explore the clinical effect of corticosteroids combined with Chinese medicine sequential therapy of Guishao Dihuang pill and Yupingfeng granules on children nephrotic syndrome (NS) with yin deficiency of liver and kidney.Methods Fifty patients (the loss of children during the course of treatment were not included in the statistical analysis) with definitely diagnosed NS accompanied by yin deficiency of the liver and kidney admitted to the First Affiliated Hospital of Gannan Medical University from January 2012 to June 2016 were enrolled,and they were divided into control group and observation group by random number table,25 cases in each group.Conventional treatment of western medicine and long-term treatment of corticosteroids were given to the two groups.In addition,sequential therapy of Guishao Dihuang pills and Yupingfeng granules was given to the observation group on the bases of conventional treatment.The changes of platelet aggregation rate (PAT),cholesterol,cortisol,T cell subsets CD3,CD4,CD4/CD8 were observed before and after treatment for 8 weeks and 6 months,then the clinical efficacy and infection,etc.complications were compared between the two groups.Results There were no statistical significant differences in cholesterol,cortisol and curative effect compared between the two groups before treatment and after treatment for 8 weeks and 6 months (all P ＞ 0.05).Mter treatment for 8 weeks and 6 months,the PAT,cholesterol,cortisol of two groups were significantly decreased compared with those before treatment,while CD3,CD4 were obviously higher than those before treatment,and the degrees of changes of PAT,CD3,CD4 in the observation group were more remarkable than those of the control group [PAT:treatment after 8 weeks was (63.01 ± 6.99)％ vs.(66.62 ± 4.65)％,treatment after 6 months was (51.42 ± 7.74)％ vs.(57.01 ± 6.77)％,CD3:treatment after 8 weeks was 0.56 ± 0.06 vs.0.52± 0.06,treatment after 6 months was 0.61 ± 0.05 vs.0.58 ± 0.03,CD4:treatment after 8 weeks was 0.33 ± 0.06 vs.0.30 ± 0.05,treatment after 6 months was 0.39 ± 0.05 vs.0.33 ± 0.06,all P ＜ 0.05].CD4/CD8 ratio was significantly higher in observation group after treatment for 8 weeks and 6 months than those before therapy (1.68 ± 0.76,1.82 ± 0.95 vs.1.16 ± 0.67,both P ＜ 0.05);the number of patients with infection in observation group was obviously lower than that of the control group (86 cases vs.175 cases,P ＜ 0.05).Conclusions The therapeutic effect of corticosteroids combined with Chinese medicine sequential therapy of Guishao Dihuang pills and Yupingfeng granules for treatment of children NS with yin deficiency of the liver and kidney is better than that of using western medicine therapy alone,as the combined sequential therapy has good effects on reduction of infection,anti-thrombosis and elevation of immunity.

Objective:This work aims to investigate diallyl disulfide (DADS) inhibition of cell migration and invasion in human colon cancer SW480 cells through the Rac1-ADF/cofilin1 pathway. Methods:The potential of cell migration and invasion was examined by scratch healing assay and transwell membrane assay. The expression of Rac1-ADF/cofilin1 pathway was detected by RT-PCR and Western blot. Results:After the SW480 cells were treated with 40 and 50 mg·L-1 of DADS for 24 h, the number of transmembrane cells through the Matrigel obviously decreased by 57.12%and 64.59%, respectively (P<0.05). After cell treatment for 48 h, the cell migration rates were 23.23%and 12.87%, which were significantly lower compared with the control group (75.86%;P<0.05). After the cells were treated with 45 mg·L-1 of DADS for 24 and 48 h, the expression of Rac1, Rock1, PAK1, LIMK1, and destrin mRNA respectively decreased compared with the control group (P<0.05). However, no significant difference was observed in the expression of cofilin1 mRNA (P>0.05). After the treatment with 45 mg·L-1 of DADS for 6, 12, 24, and 48 h, the expression of Rac1, Rock1, PAK1, LIMK1, and Destrin proteins respectively decreased in a time-dependent manner compared with the control group (P<0.05). However, no significant differences were observed in the expression of the cofilin1 protein (P>0.05). Moreover, the expression of p-LIMK1 and p-cofilin1 notably decreased in a time-dependent manner (P<0.05). Conclusion:DADS inhibits cell migration and invasion, which is related to the down-regulation of Rac1, Rock1, PAK1, LIMK1, p-LIMK1, p-cofilin1, and destrin through the Rac1-ADF/cofilin1 pathway.

OBJECTIVETo establish a new method for simultaneous determination of shanzhiside methyl ester, chlorogenic acid, 8-O-acetyl shanzhiside methylester, forsythiaside B, rutin, acteoside and galuteolin in Lamiophlomis rotata.

METHODSeparation was performed on a Welchrom-C18 chromatographic column with acetonitrile-0.1% orthophosphoric acid as mobile phasewith gradient elution. The flow rate was 1.0 mL x min(-1). The column temperature was 30 degrees C, and the detection wavelength was set at 238 nm, 330 nm and 350 nm.

RESULTThe seven compounds were well separated with good linear correlations. The mean recoveries of seven compounds were 96.47%-102.2% (RSD 0.70%-2.2%).

CONCLUSIONThere were good correlations among the seven compounds in the samples of aerial parts. The mean sum of shanzhiside methyl ester and 8-O-acetyl shanzhiside methylester in samples of aerial parts is 1.44%. The aerial parts have more kinds of composition and with higher content than that of underground parts in L. rotata, which was reasonable for the resonable use of the aerial part as medicinal part. The method was simple, repeatable and stable, which could be used for identification and quality evaluation of L. rotata.

OBJECTIVE: To investigate the effect of the course and menopause on the change of bone mineral density (BMD) in female patients with hyperthyroidism. METHODS: BMDs of hip and lumbar vertebrae were measured by dual-energy X-rays absorptiometry(DEXA) in the female patients (n=192, aged 14 approximately 72). Patients were divided into 2 groups (premenopausal and postmenopausal)and 2 subgroups(short-course and long-course). The BMDs were compared between those of age-matched, weight-matched, height-matched and body mass index matched control subgroups. RESULTS: In the premenopausal hyperthyroidic patients, only the BMDs of the second and total lumbar vertebrae with long-course were significantly lower than those of short-course group(P< 0.05). In the post-menopausal group with the long-course,each BMD measured had a lower level compared with that with short-course, of which the hip and the second lumber vertebrae were evident (P< 0.01). CONCLUSION The course and menopause have an effect on the BMDs in female patients with hyperthyroidism.

· AIM: To examine the expression of MMP-9 and TIMP-3 mRNA during choroidal neovascularization (CNV) in a murine model and to investigate the role of them in the development of CNV. · METHODS: CNV was induced in C57BL/6J mice by intensive diode laser (810nm) photocoagulation (120mW, 75μm, 0. 1s) of the fundus whereafter eyes were enucleated at 1, 3days, 1, 2, and 4 weeks. The MMP-9 and TIMP-3 mRNA expression were analyzed using in situ hybridization and image analysis system. · RESULTS: Both expression of MMP-9 and TIMP-3 mRNA had dynamic changes. For MMP-9, the expression was 1, 2, 4 wk > 3d > 1d (P < 0.05), whereas TIMP-3 mRNA, 3d, 1, 2, 4 wk>1d (P<0.05). · CONCLUSION: The imbalance between the changes of MMP-9 and TIMP-3 may accelerate the degrading of extracelluar matrix, and then be involved in the pathogenesis of CNV.

Objective To investigate the initiation pathway of corneal endothelial cell apoptosis induced by high-pression.Methods Primary rabbit corneal endothelial cells were identified by immunohistochemistry and cultured under high pressure 50 mmHg (1 kPa =7.5 mmHg) for 1 h,2 h,24 h,respectively,while cells cultured under the normal pressure 15 mmHg served as the normal pression group.In addition,the first generation of rabbits corneal endothelial ceils with 70％ to 80％ fusion were pretreated with 10-6 mol · L-1 anti-Caspase 8 and anti-Caspase 9 for lh,followed by 50 mmHg pression for the treatment of the cells;while cells cultured with no inhibitor in the same pression served as the control group.Then the expression of P53 and Bcl-2 protein was detected by Western blot,and cytochrome C in rabbit corneal endothelial cells was determined by immunofluorescence staining in all groups.Results The expression levels of P53 in the 50 mmHg group were 0.651 +0.007,0.805 ±0.006 and 0.839 ±0.011 after 1 h,2 h,24 h high-pression respectively,which were significantly higher than those in the normal pressure group (0.033 ± 0.004),and the difference approached statistical significance (all P ＜ 0.01).The expression of P53 protein in corneal endothelial cells gradually increased as time went on,and the difference was statistically significant between each two time-points (all P ＜ 0.01).Moreover,the expression of Bcl-2 in the 50 mmHg pressure group was 0.590 ± 0.009,0.724 ± 0.005 and 0.34 ± 0.016,respectively,which was higher than that in the normal pressure group (0.081 ±0.013),with signifi cant difference (all P ＜ 0.01),and the difference approached statistical significance between each two time points in this group (all P ＜ 0.01).The expression level of P53 in anti-Caspase 9 and anti-Caspase 8 group was 0.535 ± 0.007 and 0.703 ± 0.010,respectively,which was significantly lower than that in the control group (0.727 ± 0.021),and the difference was statistically significant (all P ＜ 0.01).The expression of Bcl2 was 0.312 ± 0.003 and 0.442 ± 0.011,respectively,which were significantly lower than that in the control group (0.501 ± 0.011),with statistical difference (P ＜ 0.01).Finally,the expression of P53 and Bcl-2 in anti-Caspase 9 group was lower than that of anti-Caspase 8 group (P ＜ 0.01),indicating that anti-Caspase 9 had more enhanced inhibitory effect on the apoptosis of corneal endothelial cells than anti-Caspase 8.Conclusion AntiCaspase 9 inhibitor could effectively block the corneal endothelial cell apoptosis induced by high pressure.And the damage from high pressure on corneal endothelial cells mainly triggers the release of cytochrome C from chondriosome to activate the endogenous enzyme linked apoptotic pathway in which Caspase 9 involves.

BACKGROUND:To invent a novel cardiopulmonary resuscitation (CPR) time point recorder to synchronously and automatically record the time and to identify its effectiveness in humans. METHODS:A CPR time point recorder was invented after the doctors were familiar with the traditional Utstein recovery registration mode and mastered the registration time points required. The progress of CPR was simulated. The standard and correct times were recorded, and the doctors performing the recovery collected the data about the times using our CPR time point recorder or the memory registration mode. RESULTS:The deviation times were 21.4±24.7 seconds for the memory group and 3.57±4.58 seconds for CPR time point recorder group. The deviation of times increased significantly depending on the increase of the operation items in the memory group. A similar phenomenon was found in the timer group but with a smaller difference (P<0.01). CONCLUSION: A CPR time point recorder could reduce the deviation of operate-time, especially after a long-time operation, and for procedures with more operating items, compared with the memory mode. It was a more advantageous and accurate method for the Utstein registration.

The proteins encoded by the Herpesviridae β-gene play a critical role in the replication stage of the virus. In this paper, phylogenetic analyses provided evidence that someβ-gene products, such as UL2 and UL23 from HSV1, have their homologous genes in its family, and also exist in prokaryotic organisms, indicating that these viruses appear to have been assembled over evolutionary time by numerous independent events of horizontal gene transfer.

OBJECTIVETo study the clinical and epidemiologic characteristics and the serum types of enterovirus of hand, foot and mouth disease (HFMD) in children.

METHODSThe RT-nPCR method was established with universal primers within 5' untranslated region of enterovirus and VP1 region of Coxsackievirus A16 (CAV16) and enterovirus 71 (EV 71). Enteroviruses were detected with RT-nPCR in 237 children with HFMD. Clinical and epidemiologic characteristics and serum types of enterovirus of the patients with HFMD were studied.

RESULTSThe patients'age ranged from 7 months to 11 years (mean 4.2 +/- 0.5 years). The majority (94.5%) were less than 6 years old. HFMD was mostly seen in spring and winter (67.9%). Oral mucosal pox or ulcer as well as hand and foot rashes were observed in all 237 patients. Fever occurred in 141 patients (59.5%). Of the 237 patients, 133 (56.1%) were RT-nPCR positive. Of the 133 cases, 38 were positive for EV71, 64 were positive for CAV16, and 31 were negative for both EV71 and CAV16. The patients infected by different types of enteroviruses had similar clinical characteristics. Gene colon and sequence analysis for 12 strains of enteroviruses PCR positive products presented as EV71 (n=5), CAV16 (n=5), ECHO13 (n=1), and CAV5 (n=1).

CONCLUSIONSHFMD tends to occur in younger children less than 6 years old. The majority are affected in spring and winter. EV71 and CAV16 are common pathogens of HFMD. There is no relationship between clinical characteristics and serum types of enteroviruses in HFMD patients.
