Objective To study the application of total intravenous anesthesia(TIVA) in patients with larp-aroscopic cholecystectomy(LC). Methods 100 cases with LC were randomly and evenly assigned to two groups: the combined intravenous with inhalation anesthesia(CIIA) group(n = 50) and the TIVA group(n = 50). The maintain anesthesia. BP, HR and SpO2 at all stages and time for extubation,the consciousness were recorded. Results The pneumoperitoneum after 10 min HR(96.8±13.5)times/min,SBP(142.5±14.3) mmHg、DBP(93.0±14.3) mm-Hg in A group higher than before induction of anesthesia(82.3±12.5) times/min, (129.0±21.7) mmHg, (77.3±13.5) mmHg(P < 0.05～0.01) ; The pneumoperitoneum after 10 min HR (84.0±11.0) times/min, pneumoperito-neum comphte(76.3±9.0) times/rain in B group lower than the(96.8±13.5) times/min, (84.1±11.0) times/min in A group(P >0.05); B group patients completed the opening time(6.5±1.5) min、extubation time (11.5±1.4) min、pestoperative nausea and vomiting in 3 cases,after 8 h VAS value of (2.8±1.1) in group B were lower than the (10.5±2.8) min,(25.2±9.5)min,12 cases(5.4±2.1) in group A(t =2. 411, P <0.05). Conclusion The application of TIVA to LC anesthetic effect is satisfaction.

OBJECTIVE:To establish a method for determining the content of paeoniflorin in Xiaohe syrup. METHODS:HPLC method was adopted. The Waters SunFire C18 column was used with the mobile phase of acetonitrile-0.1% phosphoric acid(12∶88, V/V)at the flow rate of 1.2 ml/min;the detection wavelength was 230 nm with column temperature at 30℃. Sample size was 10μl . R E-SULTS:There was a good linear relationship between the amount of paeoniflorin and peak area in the range of 0.061 0-1 . 2 2 0 8 μg (r=0.999 9). The RSDs of precision,stability and reproducibility tests were all less than 2% and the average recovery was 98.77%(RSD=1.09%,n=6). CONCLUSIONS:The method is simple,rapid and accurate and can be used for the content deter-mination of paeoniflorin in Xiaohe Syrup.

Objective To investigate the protective effect of indole-3-carbinol (I3C) on radiation-induced mouse bone marrow hematopoietic cell injury and the involved mechanisms. Methods (1) The bone marrow nuclear cells (BMNCs) from CD45.1 subtype of C57BL/6J mice were collected by a density gradient centrifugation method. The BMNCs were pretreated with a series doses of I3C (0 mol/L, 10-8 mol/L-10-3 mol/L) and then exposed with radiation of 137Csγ-ray (doses of irradiation were 0 Gy, 1 Gy and 4 Gy). After 18-hour culturing, the bioluminescence method was used to detect the cell viability. (2) These cells were divided into control group and 10-6 mol/L I3C group. Both groups were received the irradiation (0 Gy, 1 Gy and 4 Gy) and inoculated into the methylcellulose semi-solid culture medium to incubate 7 days, the colony forming unit-granulocyte monocytes (CFU-GM) were observed. (3) Twenty-four CD45.2 subtype mice used as the receptor were exposed with 8 Gy radiation. The CD45.1 BMNCs were divided into control group, 4 Gy irradiation group, 4 Gy irradiation and 10-6 mol/L I3C group. Donor cells were harvested from C57BL/6J (CD45.1) mice after they received various treatments, and were then mixed with competitive BMNCs from C57BL/6J (CD45.2) mice. The mixed cells were transplanted into recipient mice (8 mice/group). Flow cytometry was used to analyze the proportion of donor cells in peripheral blood of receptor. (4) The cells were divided into control group, 10-6 mol/L I3C group, 1 Gy irradiation group, 1 Gy irradiation with 10-6 mol/L I3C group. After 24-hour culturing, Western blot assay was used to detect the expression levels of nuclear factor erythroid 2-related factor 2 (Nrf2) and hemeoxygenase-1 (HO-1). Results (1) I3C showed a significant cytotoxic effect on the BMNCs when its concentration was above 10-4 mol/L. 10-7-10-6 mol/L I3C could reduce the radiation injury of BMNCs under the same dose of irradiation. Therefore, 10-6 mol/L I3C was chosen for subsequent experiments. (2) The CFU-GM was significantly higher in 10-6 mol/L I3C group than that of control group (P<0.05). (3) Results of flow cytometry showed that the proportion of donor cells in receptor was significantly higher in 4 Gy irradiation group than that of control group, which decreased the engraftment capability of irradiated HSCs (P<0.05), although the engraftment capability of irradiated HSCs improved after 10-6 mol/L I3C treatment. (4) I3C significantly enhanced the increased protein expression of Nrf2 and HO-1 caused by radiation (P<0.05). Conclusion I3C has a protective effect on hematopoietic cells following radiation-induced injury, which may be related with activating the Nrf2/HO-1 signal pathway.

Thermal Shift Assays was applied for high-throughput screening optimized buffer system used in the gel filtration chromatography for purification of recombinant TBEV serine protease. The optimization included kinds of salt and pH. It was optimized new buffer remarkably improved the quality of the purified TBEV serine protease by increasing its monomer from 75% to 99%. This result may improve future crystal studies of this protein.

Objective To observe the analgesic effect after cesarean section with different paregoric meth-ods. Methods 100 cesarean patients were randomly divided into A and B group. A group adopted patient controlled epidura analgesia(PCEA) micro-injection pump;B group using patient controlled intravenous analgesia(PCIA) mi-cro-injection pump,patients were observed and recorded for their pain, vomit disgustingly, exsufflation and the time of first urination or accidentally tube pull-out. Results The time of average surgery for A, B group were (53.5±8.5) min, (54.7±8.2) min, between the two groups was not significant (t=1.524, P>0.05) ; A group of visual Analog score (1.49±0.43) points were significantly higher than B group (1.13±0.56) points(t=2.119,P<0.05) ;the incidence of headache, dizziness, nausea and vomiting, skin itching(30.0%, 16.0% ,6.0%) in A group were signifi-candy higher than B group(16.0%,8.0% ,2.0%) (t=2.223, t=2.313, t=2.283, all P>0.05) ; the time of A first exhaust,voiding time[(24.56±8.77) h, (6.51±1.57) h] in A group were significantly higher than B group [(19.29±8.16)h,(4.06±1.76)h](t=2.445,t=2.415,P<0.05). Conclusion PCIA method was safe,effec-tive and allowed patients to have early activities after treatment and to promote early rehabilitation. It should be promo-ted for cesarean section.

By studying the physician-related factors in physicianpatient relationship,authors put forwards that excellent medical skill,good medical ethics,favorable communication ability,and adequate knowledge on relevant legal regulations are four key points to handle the physician-patient relationship harmoniously.This article will supply reference from the above aspects for the all-around quality-based education for medical students.
