Mice was stimulated by peptidoglycan from Lactobacillus sp and detect cytokines production。It was found that PG induced the production of inflammatory cytokines (IL-1,TNF-? in peritoneal macrophages,IFN-? in spleen cell)and did not induce the IL-2 production in spleen cell. Affymetrix MOE430A genechip was used to analyze changed gene expression of immune cells. It was found that expression of cytokines and related genes were changed under peptidoglycan administration. This might induced by activation of TLR-NF-?B signal pathway.

A total of 121 subjects comprising 40 normal subjects,58 patients with overweight or obesity and 23 patients with Cushing's syndrome were recruited in the study.The modified radioimmunoassay (RIA) for salivary cortisol test was established'and its normal range was determined.Then the diagnostic value of the salivary cortisol for the initial diagnosis of Cushing's syndrome was evaluated and single midnight salivary cortisol test demonstrated a sensitivity of 100.0% and specificity of 91.4 %.Salivary cortisol test can be recommended as a first-line diagnostic parameter for Cushing's syndrome.

Background Selective laser trabeculoplasty(SLT)has been widely accepted for the treatment of open-angle glaucoma.However,there are few reports about its application in treating angle-closure glaucoma so far.Objective This study was to clinically evaluate the safety and efficacy of selective laser trabeculoplasty for primary angle-closure glaucoma with opened anterior angle follow-up surgery.Methods A case-observational design was adopted in this study.A total of 33 eyes from 23 angle-closure glaucomatous patients with opened 180° angle were enrolled.All the patients understood this trial and written informed consent was obtained prior to the medical treatment.The average preoperative intraocular pressure(IOP)and number of medication were(23.07±4.01)mmHg and 1.52±0.66,respectively.A frequency doubled Q-switched Nd:YAG laser was used to irradiate the trabecular meshwork with 70-80 laser spots over 180°.The same preoperative anti-glaucoma drugs were topically administered during the follow-up period.Visual acuity,IOP,slit lamp examination,gonioscopy and the coefficient of outflow facility were regularly assessed and performed after laser surgery.Results The IOP values of the 33 eyes were(18.78±4.87)mmHg,(18.83±3.95)mmHg,(19.78±4.48)mmHg,(19.63±3.68)mmHg,(19.11±3.36)mmHg,and(21.17±3.14)mmHg 1 day,l week,and 1,3,6,9 months after operation,showing significant decline in comparison with preoperation(P＜0.01).The mean drug uses were 1.63±0.85,1.23±1.01,1.25±0.98,1.21±1.02,1.22±0.86,and 1.69±0.53 at the same time point after operation,respectively,and significant differences were found 1 week,1,3,6 months in postoperation in comparison with preoperation(P =0.020,0.026,0.020,0.031).Ciliary congestion and aqueous flare naturally disappeared 1 week after surgery.The coefficients of outflow facility were 0.11±0.09 and 0.23±0.15,respectively at pretreatment and 3 months after SLT with a statistically significant difference (P=0.002).Conclusions Selective laser trabeculoplasty is effective and safe for angle-closure glaucoma.However,it is essential to have 1/2 circle of anterior chamber open for SLT in angle-closure glaucoma.

Objective To evaluate the value of percutaneous transhepatic angioplasty in treatment of portal vein stenosis (PVS) after pediatric liver transplantation.Methods The data of 8 pediatric patients with PVS after liver transplantation were retrospectively evaluated.All cases were confirmed by portal vein angiography,and were treated with percutaneous transluminal angioplasty and/or percutaneous transluminal stent angioplasty.The effect of endovascular interventional therapy in 8 cases was analyzed.Results A total of 12 times of 8 patients received endovascular interventional therapy.The success rate was 66.67％ (8/12).The clinical success rate of the first treatment was 62.50％ (5/8).Three cases were treated with balloon dilation after the first balloon dilation,and there was no recurrence of PVS after operation in 2 cases.After the treatment of balloon dilation,stent angioplasty was performed in 1 case.There were no complications related to treatment in 8 cases.Conclusion Endovascular interventional treatment is a safe and effective way for PVS after pediatric liver transplantation.

Quantitative models were established to analyze the content of chlorogenic acid and soluble solid content in the liquid-liquid extraction of Reduning injection by near-infrared (NIR) spectroscopy. Seven batches of extraction solution from the liquid-liquid extraction of Lonicerae Japonicae Flos and Artemisiae Annuae Herba were collected and NIR off-line spectra were acquired. The content of chlorogenic acid and soluble solid content were determined by the reference methods. The partial least square (PLS) and artificial neural networks (ANN) were used to build models to predict the content of chlorogenic acid and soluble solid content in the unknown samples. For PLS models, the R2 of calibration set were 0.9872, 0.9812, RMSEC were 0.1533, 0.7943, the R2 of prediction set were 0.9837, 0.9733, RMSEP were 0.2464, 1.2594, RSEP were 3.25%, 3.31%, for chlorogenic acid and soluble solid content, respectively. For ANN models, the R2 of calibration set were 0.9903, 0.9882, RMSEC were 0.0974, 0.4543, the R2 of prediction set were 0.9868, 0.9699, RMSEP were 0.1920, 0.9427, RSEP were 2.61%, 2.75%, for chlorogenic acid and soluble solid content, respectively. Both the RSEP values of chlorogenic acid and soluble solid content were lower than 6%, which can satisfy the quality control standard in the traditional Chinese medicine production process. The RSEP values of ANN models were lower than PLS models, which indicated the ANN models had better predictive performance for chlorogenic acid and soluble solid content. The established method can rapidly measure the content of chlorogenic acid and soluble solid content. The method is simple, accurate anc reliable, thus can be used for quality control of the liquid-liquid extraction of Reduning injection.

Near infrared (NIR) spectroscopy as a kind of rapid process analysis technology has been successfully applied in Chinese medicine pharmaceutical process. In this research, the technology was adopted to establish the rapid quantitative analysis models of main indicators from the Lonicera japonica and Artemisia annua alcohol precipitation process of Reduning injection. On-line NIR spectra of 142 samples from alcohol precipitation process were collected and the content of main indicators for each sample were detected through off-line HPLC. With eliminating outliers, determination of spectra pretreatment method and selecting optimal band, the NIR quantitative calibration model for each indicator was established using partial least squares (PLS). These models were used to predict the unknown samples from precipitation process of Reduning injection to achieve the goal of rapid detection. The results showed that the models were ideal. The correlation coefficients of models for neochlorogenic acid, chlorogenic acid, 4-O-caffeoylquinic acid and secoxyloganin were 0.973 872, 0.985 449, 0.975 509 and 0.979 790, respectively and their relative standard errors of prediction (RSEP) were 2.922 49%, 2.341 37%, 2.930 40% and 2.184 60%, respectively. This study indicated that the NIR quantitative calibration model showed good stability and precision, and it can be used in rapid quantitative detection of main indicators of efficacy in order to on-line monitor the alcohol precipitation process of Reduning injection.
