OBJECTIVE To analyze the metabolites of Zhideke granules and speculate its metabolic pathway in rats in vivo. METHODS Male SD rats were randomly divided into blank group and administration group （Zhideke granules， 9.45 g/kg）； they were given ultrapure water or relevant medicine， twice a day， every 6-8 h， for 3 consecutive days. Serum， urine and feces samples of rats were collected， and their metabolites were identified by UPLC-Q-Exactive-MS technique after intragastric administration of Zhideke granules； their metabolic pathways were speculated. RESULTS After intragastric administration of Zhideke granules， 16 prototype components （i.g. irisflorentin， baicalin， chlorogenic acid） and 11 metabolites （i.g. hydration products of kaempferol or luteolin， methylation products of chlorogenic acid， and hydroxylation products of baicalin） were identified in serum， urine and feces of rats. Among them， 8 prototype components and 4 metabolites were identified in serum samples； 10 prototype components and 7 metabolites were identified in urine samples； 8 prototype components and 5 metabolites were identified in the fecal samples. CONCLUSIONS The metabolites of Zhideke granules in rats mainly include baicalin， irisflorentin，chlorogenic acid， and the main metabolic pathways included methylation， hydroxylation， glucuronidation.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

OBJECTIVE：To optimize the extraction technology of Zhideke granules. ME THODS：The extraction technology （water extraction ，alcohol extraction ，water extraction and ethanol precipitation ）of Zhideke granules was initially screened by ammonia-induced cough experiment and xylene-induced ear swelling experiment in mice. Based on its preparation route ，the immersion time of medicinal materials containing volatile oil was investigated with water absorption as index firstly. The single factor test was adopted to investigate the amount of water added and the extraction time taking the volatile oil yield as index to optimize the extraction technology of medicinal materials containing volatile oil. Taking the contents of irisflorentin and total flavonoids as indicators ，on the basis of single factor investigation ，orthogonal test was adopted to examine the influence of three factors including the amount of water added ，extraction time and extraction frequency ，so as to optimize the water extraction technology of Zhideke granules and the validation tests were conducted. RESULTS ：The results of pharmacodynamics experiment showed that the cough latency of mice in water extract low-dose and high-dose groups （6.34，12.68 g/kg，by crude drug ）and water-extraction alcohol-precipitation extract high-dose group （12.68 g/kg，by crude drug ）were significantly longer than those inmodel group ，and the number of cough within 2 minutes was significantly reduced （P＜0.05 or P＜0.01）. Compared with model group ， the ear swelling of mice in water extract low-dose and high-dose groups （6.34，12.68 g/kg，by crude drug），ethanol extract high-dose group （12.68 g/kg，by crude drug） and water-extraction alcohol-precipitation extract hig dose group （12.68 g/kg，by crude drug ） were decreased significantly （P＜0.05 or P＜0.01）. The swelling inhibition rates were 42.26％，55.08％，33.49％，51.56％，39.57％ and 44.36％ in low-dose and high-dose groups of water extract ，alcohol extract ， water-extraction and alcohol-precipitation extract respectively ，indicating that the water extract had better antitussive and anti-inflammatory effects. The optimal extraction technology of volatile oil was adding 5-fold water ，soaking for 30 minutes，and extracting for 3 hours. The optimal water extraction technology was adding 12-fold water ，extracting for 3 times after soaked for 50 min，lasting for 1 h each time. Results of 3 times of validation tests showed that average content of irisflorentin in the extract obtained by optimal technology was 76.47 μg/g（RSD＝ 2.15％，n＝3）and the average content of total flavonoids was 92.45 mg/g（RSD＝0.48％，n＝3）. CONCLUSIONS ：The optimal extraction technology of Zhideke granules is stable and feasible.

Objective Inflammation plays a critical role in the presence , development and maintenance of atrial fibrillation ( AF) , but it remains unclear what factors induce inflammation in AF patients , especially in those with valvular heart disease ( VHD) . The aim of this paper was to investigate the role of the shedding of Syndecan -4 in left atrial inflammation in patients with valvular atrial fibrillation. Methods Sixty VHD patients scheduled for valvuloplasty or valve replacement surgery were divided into three groups of equal number:sinus rhythm (SR), paroxysmal atrial fibrillation (PaAF), and persistent atrial fibrillation (PeAF).Another 10 pa-tients with congenital heart disease but no valve damage and atrial fibrillation were included in a control group .Baseline clinical data were recorded and tissues were obtained from the left atrial appendage during operation .The expressions of iNOS , HMGB1, and Syn-decan-4 in the left atrium were detected by Western blot , and the pathological changes of the left atrial tissue observed by HE staining . Results Western blot analysis was performed to detect expression levels of proteins .The iNOS level was significantly higher in pa-tients from the paroxysmal AF group (1.61 ±0.10) and persistent AF group (1.67 ±0.08) than those from sinus group (1.06 ± 0.11) and control group (1.02 ±0.12), as was the protein level of HMGB1 (0.63 ±0.05, 0.95 ±0.10, 0.45 ±0.07 and 0.46 ± 0.06 in paroxysmal AF group, persistent AF group, sinus group and controlgroup respectively ).Inflammatory cell infiltration in-creased, while syndecan 4 was down-regulated in AF groups.All these comparisons were significant (P<0.05). Conclusion The decreased expression of Syndecan-4 and enhanced inflammatory response in the left atrial tissue indicate that the shedding of Synde-can-4 may play a role in the presence and development of inflamma-tion in the left atrium .

To solve the calibration transmission problem in near-infrared ( NIR) spectroscopy, a novel model transfer method, Simple Linear Regression Direct Standard-ization ( SLRDS ) , has been presented. To investigate the validity of the proposed method, a real corn sample NIR dataset was tested and the direct standardization ( DS ) method and piecewise direct standardization ( PDS ) method were involved as a comparison. Our results indicated that SLRDS can correct compressed NIR data differences among instruments and enable the user to share corn sample PLS calibration model among three instruments, at the same time it has higher prediction accuracy, fewer parameters and simpler model than DS and PDS.
