Patients′ clinical data, complications and therapeutic effects of endoscopy were retrospectively analyzed. Results All patients underwent endoscopy successfully. No recurrent bleeding was found in any case after treatment. Eight cases of varicosis nearly disappeared. Six?month follow?up showed three cases of gastrointestinal bleeding, one case of death of bleeding, and no recurrence hemorrhage in 27 others. Conclusion Endoscopic treatment could safely and effectively control the primary liver cancer combined with gastroesophageal variceal hemorrhage, hence may provide opportunity for further treatment of liver cancer.

Objective: To optimize the water extraction process of Siwu Decoction by BP neural network combined with orthogonal experiment. Methods: The water amount, the extraction time, and the extraction times were taken as factors. Entropy weight method was used to calculate the comprehensive scores of the multi-indicators of eight active components of 5-hydroxymethylfurfural, chlorogenic acid, caffeic acid, paeoniflorin, ferulic acid, verbascoside, senkyunolide A, and ligustilide in R language environment. Using comprehensive score as an evaluation indicator, the BP neural network model was established by orthogonal experiment design, and the optimal water extraction process of Siwu Decoction was predicted through network training. Results: The optimized extraction process of Siwu Decoction was carried out by adding 8 times of water and extracting 3 times for 1 h. The relative error between the network predicted value and the actual measured value of the test sample was less than 1%. Conclusion: The established mathematical model can analyze and predict the water extraction process of Siwu Decoction. The obtained process is stable and feasible, and can effectively extract the active ingredients in Siwu Decoction.

?ig-h_3 was first identified as a transforming growth factor-beta1-inducible gene in human lung adenocarcinoma cell line. It encodes for a secreted extracellular matrix (ECM) protein, which is thought to act on cell attachment and ECM composition. Previous study showed that ?ig-h_3 were highly expressed in human hepatoma cell lines and lowly expressed in human normal hepatic cells. The present study aimed to transfect ?ig-h_3 into 7721 cells to investigate its effect on secretion of MMPs in the transfected human hepatoma cells. Full-length ?ig-h_3 gene,cloned by reverse transcription polymerase chain reaction (RT-PCR) was inserted into the eukaryotic expression vector pEGFP-C_2. The recombinant plasmid was transfected into 7721 cells with Lipofectamine2000 and Gelatin-Zymography were adopted to detect the production of MMPs in the transfected cells. Results showed that ?ig-h_3/pEGFP-C_2 recombinant expression plasmid was successfully constructed and achieved high transfection efficiency. MMPs expression of the transfected cells was promoted significantly. These results suggest that overexpression of ?ig-h_3 promoted the production of MMPs, indicating that ?ig-h_3 may play roles in the invasive and metastatic processes of hepatoma.

Objective To assess the application of Chinese children's intelligence equation (CCIE) and Bayley Scales of infant and toddler development-Ⅲ (BSID-Ⅲ) in screening of postoperative cognitive dysfunction (POCD) in children after general anesthesia.Methods The study group (Group A),including 50 ASA-Ⅰ participants of 1-3 years old who would undergo hernia repair laparoscopic surgery,was assessed on one day (1 d) before and three days (3d) after the surgery respectively by both of CCIE and BSID-Ⅲ according to their ages of month.The control group (Group C),including 50 healthy participants with the matched age,was assessed in the same period by the same method.Both of Group A and C were assessed by the Z score method to diagnose POCD and both scales were used to analyze the results of POCD screening and their agreement.Results (1) Compared with preoperative 1 d,the CCIE score of Group A on 3d after surgery was relatively decreased (21.22±4.96 vs 18.65±4.74,P＜0.05) and the POCD rate was 12.0％.While in Group C,the CCIE score and the POCD rate had no statistical significance (20.83±4.97 vs 21.22±5.21,P＞0.05).(2) Compared with preoperative 1d,the scores of cognition,language,motion,social-emotion and adaptive behaviors in BSID-Ⅲ of Group A decreased (100.00±4.58 vs 96.44± 4.20,103.22±4.99 vs 96.24± 5.75,102.06±4.01 vs 95.28±4.27,101.22±7.38 vs 91.06±7.10,98.52±9.11 vs 90.5±8.47,P＜0.05) and the POCD incidence was 20.0％.While in group C,the BSID-Ⅲ score and the POCD rate had no statistical significance (104.61±5.48 vs 103.79±5.38,107.68±5.60 vs 107.11 ±6.05,108.29±5.91 vs 108.29±4.21,101.11±7.61 vs 101.86±6.99,99.00±7.99 vs 100.82±7.36,P＞0.05).(3)Reasonable agreement of the CCIE and BSID-Ⅲ was observed (Kappa value was 0.70;P＜ 0.05).Conclusion There is considerable agreement between BSID-Ⅲ and CCIE.While BSID-Ⅲ is relatively more sensitive to the POCD and more efficient in the diagnosis of POCD than the CCIE.Thus,BSID-Ⅲ is more likely to provide better evaluation of the postoperative cognitive functions of children within 1-3 years old and should be recommended to the health professionals in China.

Objective To investigate the safety and efficacy of endoscopic tissue adhesive injection combined with sequential endoscopic variceal ligation for gastroesophageal varices of Le,g type. Methods Twenty-three patients with gastroesophageal varices of Le,g type were enrolled to General Hospital of PLA from May 2013 to March 2015, who were treated with endoscopic tissue adhesive injection in the fundic and cardiac site in the first session, followed with endoscopic variceal ligation for esophageal varices. The clinical data, procedure complications and efficacy were retrospectively analysed. Results All procedures were successfully performed with no such evident complications as intraoperative and postoperative bleeding, embolization, mediastinal infection or death with an average hospitalization time of 15. 3±4. 09 days. Mild and moderate thoracalgia occurred in 13 patients(56. 5%), low-grade fever in 2 patients(8. 7%, recovered after symptomatic treatment for 1-2 days) . During the follow-up of 2 weeks, the rate of varices disappearance was 56. 5% (13/23) and no recurrent bleeding was observed. Six months after discharge, 10 patients underwent endoscopy again, varices disappeared in 4 and 6 with remains;the 13 others showed no hemorrhage according to follow-up call. Conclusion The therapy of endoscopic tissue adhesive injection with sequential endoscopic variceal ligation for gastroesophageal varices of Le,g type is safe and efficient.

Objective:To evaluate the benefit of autologous stem cell transplantation (ASCT) as a consolidation therapy in the survival of multiple myeloma (MM) patients at different risks. Methods:A total of 67 MM patients who received ASCT as consolida-tion therapy between August 2006 and July 2011 were enrolled in the retrospective study. The cases were divided into three risk groups on the basis of the International Staging System and fluorescence in situ hybridization. Another 67 patients who accepted consolidation chemotherapy at the same period were selected as case-paired controls matched in terms of age, sex, optimal response after induction, and risk stratifications. All the patients received bortezomib-and/or thalidomide-based induction therapies. Results:No statistical differ-ences in non-complete remission (nCR)/complete remission (CR) rate were observed between the ASCT and chemotherapy groups (44.8%vs. 37.3%, P=0.380) after the induction therapy. The progression-free survival (PFS) was longer in the ASCT group than in the chemotherapy group (32.4 months vs. 15.1 months, P<0.001). The overall survival (OS) was longer in the ASCT group than in the che-motherapy group (58.8 months vs. 42.1 months, P=0.009). both the PFS (median:30.5 months vs. 11.2 months, P<0.001) and the OS (median:85.5 months vs. 34 months, P=0.015) rates were significantly prolonged in the high-risk subgroup after ASCT. In the interme-diate-risk subgroup, neither PFS nor OS showed any significance after ASCT (P>0.05). In the low-risk subgroup, only PFS was extend-ed (median: 34.8 months vs. 17.6 months, P=0.012) after ASCT, without significant improvements in the OS (P>0.05). Conclusion:The MM patients obtained cytogenetic high-risk benefits mostly from ASCT consolidation after inductions based on novel agents.
