OBJECTIVE To explore the intestinal absorption characteristics of saikosaponins. METHODS Based on everted intestinal sac model, using accumulative absorption amount (Q) and absorption rate constant (Ka) as indexes, UHPLC-MS/MS technique as a method, the absorption of saikosaponin A, B2, C, D and F from total saponins of Bupleurum chinense (8 g/mL, by crude drug) in the duodenum, jejunum and ileum was detected. RESULTS The correlation coefficients (r) of the regression equations for the absorption of saikosaponins A, B2, C and F in the duodenum, jejunum and ileum were all higher than 0.95, while the r of saikosaponin D in the above intestinal segments was lower than 0.95; compared with the absorption of the same composition in the duodenum, the Q and Ka of saikosaponin A and C circulating in jejunum and ileum for 120 min, as well as the Q and Ka of saikosaponin F circulating in the ileum for 120 min were significantly decreased (P<0.05). CONCLUSIONS Saikosaponin A and the other 4 saikosaponins are all absorbed in the duodenum, jejunum and ileum; among them, saikosaponin A, B2, C and F are linearly absorbed, which conforms to the zero-order absorption characteristics, but saikosaponin D shows non- linear absorption.

Objective:To investigate the relationship between single nucleotide polymorphism (SNPs) of Zeste homolog enhancer 2 (EZH2) gene and the risk of breast cancer.Methods:Recruiting 1 039 breast cancer patients and 1 040 controls at 22 referral hospitals nationwide in China, the genotype distribution of 3 SNPs loci of EZH2 genes was observed to detect the correlation between different genotypes and the risk of breast cancer genotypes EZH2 expression in breast cancer tissues and its correlation with patient prognosis were analyzed using breast cancer data from the database.Results:EZH2 rs6464926 CC genotype was compared with TT genotype (TT vs. CC: OR=1.362, 95% CI: 1.063-1.746, P=0.015) and dominant model (TC+TT vs .CC: OR=1.22, 95% CI: 1.004-1.483, P=0.045) .In women with BMI ≥24 kg/m 2, the TC genotype ( P=0.050), TT genotype ( P=0.025) and dominant model (TC+TT, P=0.021) of rs6464926 locus were significantly different from CC genotype in cancer risk. rs6464926 was correlated with EZH2 gene expression ( P=6.89E-47). EZH2 gene is highly expressed in breast cancer tissues, and patients with high expression were associated with shorter OS ( HR=1.27, P=0.013), DMFS ( HR=1.37, P<0.01), and RFS ( HR=1.44, P<0.01). Conclusions:The polymorphism rs6464926 of EZH2 gene is associated with breast cancer susceptibility in Chinese women. rs6464926 might regulate breast cancer risk and prognosis by changing EZH2 expression.

Objective To compare ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) and chemiluminescence immunoassay(CLIA) measurement of human serum androgen levels in polycystic ovarian syndrome(PCOS). Methods 160 PCOS patients and 146 healthy subjects(control group) were recruited and their serum androgen levels——measurements of testosterone and dehydcoepiandrosterone sulfate (DHEA-S) were tested by UPLC-MS/MS and CLIA. The androgen results combined with body mass index(BMI) were analyzed by ROC curve. According to area under curve(AUC) calculated by SPSS, a better method will be selected to provide accurate test results for physicians. Results (1)AUC of DHEA-S tested by UPLC-MS/MS was significantly higher than the one tested by CLIA(P<0.01). There was no significant difference between the AUC of T tested by UPLC-MS/MS and the one tested by CLIA. (2)AUC of T combined with DHEA-S tested by HPLC was not only significantly higher than the AUC of two combined indicators tested by CLIA(P<0.01),but also significantly higher than the AUC of a single indicator——either T(P<0.01) or DHEA-S(P<0.01) tested by UPLC-MS/MS. (3)The AUC of T,DHEA-S combined with BMI tested by HPLC was not only significantly higher than the AUC of three combined indicators tested by CLIA(P<0.01),but also higher than the AUC of two combined indicators tested by UPLC-MS/MS(P<0.05). Conclusion T and DHEA-S tested by UPLC-MS/MS combined with BMI has a certain reference value in the diagnosis of PCOS.

Objective:
To summarize the measures and experience of treatment in mass extremely severe burn patients.
Methods:
The clinical data and treatment of 8 extremely severe burn patients in August 2 Kunshan factory aluminum dust explosion accident who were admitted in the 100th Hospital of PLA on August 2nd, 2014, were retrospectively analyzed. There were 4 males and 4 females, aging 22-45 (34±7) years, with total burn area of 55%-98% [(89±15)%] total body surface area (TBSA) and full-thickness burn area of 45%-97% [(80±21)%] TBSA. All the 8 patients were accompanied with severe shock, inhalation injury, and blast injury. According to the requirements of former PLA General Logistics Department and Nanjing Military Command, a treatment team was set up including a special medical unit and a special care unit, with Chai Jiake from the First Affiliated Hospital of PLA General Hospital as the team leader, Zheng Qingyi from the 175th Hospital of PLA (the Affiliated Dongnan Hospital of Xiamen University) as the deputy leader, the 100th Hospital of PLA as the treatment base, and burn care, respiratory, nephrology, nursing specialists from the First Affiliated Hospital of PLA General Hospital, and the burn care experts and nursing staff from the 180th Hospital of PLA, 118th Hospital of PLA, 98th Hospital of PLA, and 175th Hospital of PLA, and nurses from the 85th Hospital of PLA, 455th Hospital of PLA, 101th Hospital of PLA, 113th Hospital of PLA as team members. Treatment strategies were adopted as unified coordination by the superior, unified responsibility of team leader, division of labor and cooperation between team members, and multidisciplinary cooperation led by department of burns. With exception of one patient who received deep vein catheterization before admission, the other 7 patients were treated with deep vein catheterization 0.5 to 3.0 hours after admission to correct hypovolemic shock as soon as possible. Eight patients received tracheotomy, and 7 patients were treated with mechanical ventilation by ventilator in protective ventilation strategy with low tide volume and low volume pressure to assist breathing. Fiberoptic bronchoscopy was done one to three times for all the 8 patients to confirm airway injuries and healing status. Escharectomy and Meek dermatoplasty in the extremities of all the 8 patients were performed 3 to 6 days after injury for the first time. Escharectomy, microskin grafting, and covering of large pieces of allogeneic skin on the trunks of 4 patients were performed 11 to 16 days after injury for the second time. The broad-spectrum antibiotics were uniformly used at first time of anti-infective therapy, and then the antibiotics species were adjusted in time. The balance of internal environment was maintained and the visceral functions were protected. One special care unit was on responsibility of only one patient. Psychological intervention was performed on admission. The rehabilitative treatment was started at early stage and in company with the whole treatment.
Results:
Acute renal injury occurred in 5 patients within 36 hours after injury and their renal function was restored to normal 4 days after injury due to active adjustment of fluid resuscitation program. No pulmonary complications, such as severe pulmonary infection and ventilator-associated pneumonia, occurred in the survived patients. One of the 8 patients died, and the other 7 patients were cured successfully. The wounds were basically healed in 2 patients in 26 or 27 days by 2 or 3 times of operation, and in 5 patients by 4 or 5 times of operation. The basic wound healing time was 26-64 (48±15) days for all the 7 patients.
Conclusions
Treatment strategies of unified coordination by the superior, unified responsibility of team leader, division of labor and cooperation between team members, and multidisciplinary cooperation led by department of burns are the bases to successful treatment. Correcting shock as soon as possible is the prerequisite and closing wound as soon as possible is the key to successful treatment. Comprehensive treatment measures, such as maintaining and regulating the function of viscera, improving the body immunity, and preventing and treating the complications, are the important components to successful treatment. It is emphasized that in the treatment of mass extremely severe burn patients, specialist burn treatment should always be in the dominant position, and other related disciplines may play a part in auxiliary function.

Objective: The aim of the study is to validate whether the Recognition Of Stroke In the Emergency
Room (ROSIER) scale can be used by general practitioners (GPs) in an emergency medical service
(EMS) protocol to transfer stroke patients from primary care center to advanced hospital with acute
stroke center. Methods: GPs prospectively performed the ROSIER scale and the Cincinnati Prehospital
Stroke Scale (CPSS) on suspected stroke patients as a transfer protocol. All patients were immediately
transferred to the Level-II hospital for further treatment. Results: 468 of the 512 suspected stroke
patients met the inclusion criteria in this study. The ROSIER scale showed a diagnostic sensitivity
of 83.13% (95% confidence intervals [CI] 79.74-86.52%) and specificity of 80.88% (95% CI 77.32-
84.44%). The CPSS showed a diagnostic sensitivity of 78.01% (95% CI 74.26-81.76%) and specificity
of 70.59% (95% CI 66.46-74.72%). The Kappa statistic value of the ROSIER scale and the CPSS
were 0.601 and 0.454, respectively. The area under the curve (AUC) of ROSIER scale was large than
the CPSS (AUC 0.855 vs. 0.791). However, the difference was not significantly different.
Conclusions: This study suggest that ROSIER and CPSS could be used in an EMS protocol to transfer
stroke patients from a primary care center to an advanced hospital offering thrombolysis service
