Objective:To research the stability of Dazhu Hongjingtian injection combined with four different infusion solutions (0. 9% sodium chloride injection, 5% glucose injection, fructose injection, xylitol and sodium chloride injection) . Methods:The insolu-ble particles and pH value of Dazhu Hongjingtian injection in 0, 0. 5,1,2,4 and 8h after the combination were detected by the methods described in China Pharmacopeia ( 2010 edition ) . Results: Dazhu Hongjingtian injection combined with the four infusion solutions showed no significant changes in appearance and pH value in 8h. The number of insoluble particles in Dazhu Hongjingtian injection combined with 0. 9% sodium chloride injection and 5% glucose injection met the requirement in the pharmacopeia, and that in 0. 9%sodium chloride injection was lower than that in 5% glucose injection. The quantity of insoluble particles in Dazhu Hongjingtian injec-tion combined with fructose injection exceeded the standard level, and showed remarkable change in the fourth hour. The quantity of insoluble particles in xylitol and sodium chloride injection slightly exceeded the standard. Conclusion: Dazhu Hongjingtian injection can be mixed with 0. 9% sodium chloride injection and 5% glucose injection, and fructose injection and xylitol and sodium chloride in-jection are not suitable for the solvent of Dazhu Hongjingtian injection. Although there is no instruction indicating that 0. 9% sodium chloride injection can be used as the suitable solvent for Dazhu Hongjingtian injection, the results of the experiment can be reasonable reference for diabetes patients treated with Dazhu Hongjingtian injection.

Objective To summarize the causes of death and to analyze the risk factors in a surgical intensive care unit (SICU).Methods The relevant information of patients died in the SICU of Xijing Hospital of Fourth Military Medical University in past 15 years (from December 1999 to February 2015) was retrospectively analyzed.The gender,age, reason and date of hospitalization, date of transfer SICU, past medical history, whether or not admitted directly from emergency department, or transferred from other department, operated or not, date of death, the main cause of death, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, the history of undergoing mechanical ventilation, continuous renal replacement therapy (CRRT), or antifungal therapy, as well as the ratio of the patients with body temperature higher than 39 ℃, white blood cell (WBC) count higher than 10 × 109/L, platelet (PLT) count below 100 × 109/L, albumin (Alb) below 35 g/L of two periods, namely from December 1999 to July 2007 (the first period),and from August 2007 to February 2015 (the second period) were compared.The above parameters were compared with those of 201 survivors in SICU, and the risk factors leading to death were analyzed by logistic regression.Results From December 1999 to February 2015, 4 317 patients were taken care of in the SICU.Among them, the number of death was 186, and the mortality rate was 4.3％.In the first time period (from December 1999 to July 2007), the total number of patients was 1 356, and the number of death were 109 (the mortality rate was 8.0％).In the second period, i.e.from August 2007 to February 2015, the number of SICU patients was 2 961, and 77 died (the mortality rate was 2.6％).The difference of mortality rate between the two periods was statistically significant (x2 =66.707, P =0.001).The death rate of patients transferred directly from emergency department in tle first period was 79.8％ (87/109), and it was lower in the second period (51.9％, 40/77, x2 =16.181, P =0.001).The death rate of the patients with blood Alb below 35 g/L in the second period (59.7％, 46/77) was higher than that of the first period (41.3％, 45/109, x2 =6.151, P =0.017).The top three causes of death from December 1999 to February 2015 were sepsis (38.2％), trauma (16.7％), and operation for cancer (14.0％).In the first period, the top three causes of death were sepsis (35.8％), trauma (22.0％),and operation for cancer (13.8％).In the second period, the top three causes of death were sepsis (41.6％), damage of the central nervous system (16.9％), and operation for cancer (14.3％).Top three reasons for SICU admission were trauma (29.03％), abdominal pain (20.97％) and other reasons (18.82％).Top three departments from which the patients were transferred were the emergency department (19.35％), orthopedics department (17.20％), and hepatobiliary department (16.13％).Logistic regression analysis showed that age [odds ratio (OR) =2.025, 95％ confidence interval (95％CI) =1.500-2.734, P =0.000], mechanical ventilation (OR =3.514, 95％CI =1.701-7.259, P =0.001), CRRT (OR =5.604,95％CI =3.003-10.459, P =0.000), body temperature higher than 39 ℃ (OR =1.992, 95％CI =1.052-3.771, P =0.034) were the risk factors of death in SICU patients.Conclusion Sepsis and severe trauma are the leading causes of death in severe SICU patients, to whom with risk factors of death enough attention should be given.

Objective:To analyze KCNJ5 mutation of adenomas in patients with aldosterone-producing adenoma (APA) companying with hypokalemia, and to compare the clinical characteristics of patients with and without KCNJ 5 mutations.Methods:Clinical data of 144 APA patients were retrospectively analyzed. DNA were extracted from adenoma tissues, and amplified and sequenced for KCNJ5 gene. The serum potassium level and cardiac complications in patients with and without KCNJ5 gene mutation were compared.Results:Among 144 tumors, 131 tumors (91%) had KCNJ5 mutation, including 68 tumors with G151R, 56 tumors with L168R, 5 tumors with E145Q, and two tumors with novel mutations, V156_K160delITE and G151delinsVR. Compared with patients without KCNJ5 mutation, patients with KCNJ5 mutation had lower preoperative serum potassium levels, more cardiac complications, lower postoperative systolic blood pressure, and better postoperative hypertension relief. There were no statistical differences in age, gender, blood pressure, serum potassium level, plasma renin activity or plasma aldosterone concertration.Conclusion:91% adenomas in patients with APA and hypokalemia had KCNJ5 mutation, suggesting that KCNJ5 mutation is the main cause in these patients.

Objective To explore the specific role of autophagy and ubiquitin-proteasome pathway in apoptosis, specific protease inhibitor and (or) macroautophagy inhibitors.Methods The stimulators were selected to work on the pheochromocytoma (PC12) cell lines transfected with human mutant α-synuclein (A53T).Cell activity and apeptosis rate were detected by MTT law and flow cytometry.NO energy, heat shock protein 70 (Hsp70) and Caspase-3 expression were determined in cell culture.Results A53T cell survival rate significantly decreased 24 hours after handling with the protease inhibitor (100 nmol/L) and (or) autophagy inhibitors 3-MA (10 mmol/L, A =0.23±0.01,0.19±0.01 and 0.17±0.01 respectively; P <0.05) compared with the control group (A =0.32±0.06).Cell survival rate was significantly higher than the other drug group after 24 hours handling with autophagy stimulators (A =0.44±0.08).Compared with the control group or autophagy stimulator of rapamycin (0.2 μg/ml) group (1.55%±1.15%), A53T cells apeptosis percentage rate was significantly higher after treated with proteasome inhibitor and macroautophagy inhibitors 24 hours (4.74%±0.91%, 4.59%±1.18% and 5.40%±1.75%respectively, P <0.05); and a slight decrease with stimulators.Protein Hsp70 and NO were significantly higher in proteasome inhibitor groups than the control group.But in antophagy inhibitor and stimulator group, NO and Hsp70 protein was similar to the control group.Conclusion The inhibition of macroautophagy and proteasome can promote apoptosis.Inhibiting or stimulating autophagy has less impact on Hsp70 and NO than proteasome pathway.
