Objective To investigate the effects of controlled hypotension induced with sodium nitroprusside (SNP) or nicardipine on hemodynamics during hip operation and postoperative hepatic and renal function.Methods Twenty ASA Ⅰ or Ⅱ patients aged 20-70 yrs weighing 50-80 kg scheduled for total hip replacement or open reduction and internal fixation of fracture of acetabulum were randomized to receive either SNP (group Ⅰ ) or nicardipine (group Ⅱ ) for induced hypotension during operation. Each group included 10 patients. Radial artery and right internal jugular vein were cannulated for BP and CVP monitoring. The probe of Hemo-Sonic ?100 esophageal supersonic hemodynamic monitor (Arrow U.S.A) was placed in the esophagus and fixed when best signal was obtained. ECG, hemodynamics including MAP, HR, CVP, CO and other parameters, SpO2 and PetCO2 were continuously monitored. Anesthesia was induced with propofol 2 mg?kg-1 , fentanyl 2-3 ?g? kg-1 and vecuronium 0.1 mg?kg-1 and maintained with 1.5% isoflurane and continuous infusion of propofol ( at 4-6 mg?kg-1 ?h-1 ) and intermittent i.v. boluses of vecuronium after tracheal intubation. MAP was reduced to 55-65 mm Hg with SNP (at a rate of 0.5-8.0 ?g?kg-1?min-1 ) or nicardipine (at 1.0-8.0 ?g?kg-1 ?min-1 ) . Intraoperative blood loss and blood transfusion and postoperative drainage from the wound were measured and recorded.Hemodynamic parameters were recorded before hypotension and 15, 30 and 60 min after start of induced hypotension and 15 and 30 min after recovery from hypotension. Hepatic and renal functions were measured before and after operation using total bilirubin, AST, ALT, BUN and creatinine. Results The two groups were comparable with respect to sex ratio (M/F) , age, height, body weight, duration of induced hypotension and operation. MAP and systemic vascular resistance (SVR) were significantly reduced and tachycardia developed during hypotension in both groups. The left ventricular ejection time was significantly prolonged and aortic blood flow (ABF) and cardiac output (CO) were significantly increased and CVP was lowered during hypotension as compared to the baseline values in SNP group. BUN was significantly reduced after operation ( P

Objective: To observe the clinical effects of moxibustion at abdominal acupoints for slow transit constipation (STC) due to yang deficiency of the spleen and kidney. Methods: A total of 52 cases with slow transit constipation in conformity with the inclusion criteria were selected and divided into a control group and an observation group according to their visit order and random digital table, 26 cases in each group. Patients in the control group received routine nursing guide. Besides the same routine nursing guide, patients in the observation group received moxibustion at the abdominal acupoints, once every day. The course of the treatment was 4 weeks in the two groups, and the 3-month follow-up was given after the course was finished, for comparing the clinical symptoms, results of colon transit tests, scores of depression/anxiety scale and nursing satisfaction. Results: The total effective rate was 92.3% in the observation group and 69.2% in the control group, with a significant difference between the two groups. After the treatment and during the follow-up checks, the scores of Chinese medical symptoms in the two groups were remarkably decreased than those before the treatment (all P<0.01); the scores of the observation group were obviously lower than those in the control group (all P<0.01). The discharge rates of the markers in the two groups were remarkably increased than those at the same time period before the treatment; moreover, the discharge rates of the markers at various time periods were remarkably better in the observation group than those in the control group (P<0.01). SDS and SAS scores were remarkably decreased after the treatment in the two groups (P<0.01). In comparison of SDS score between the two groups after the treatment, the difference was statistically significant (P<0.01). In comparison of SAS score between the two groups after the treatment, the difference was statistically significant (P<0.05). The nursing satisfaction was 96.2% in the observation group after the treatment, obviously better than that in the control group (73.1%). The recurrence rate was 8.3% in the observation group, remarkably lower than that in the control group (33.3%). Conclusion: Moxibustion at the abdominal acupoints plus routine nursing can remarkably improve the colon transit functions and anxious and depressive emotion in patients with STC, and the therapeutic effects are remarkable. Not only the clinical satisfaction is higher, but the recurrence rate is obviously lower than that of routine nursing.

Objective To analyse the long-term result and prognosis of 18 FDG PET/CT positioning three - dimensional conformal radiotherapy ( 3 DCRT ) for stage Ⅲ non - small cell lung cancer. Methods Sixty-four cases with stage Ⅲ non-small cell lung cancer (clinical stage Ⅲa- Ⅲb ) were randomly divided into two groups: PET/CT positioning three-dimensional conformal radiotherapy group (PET/CT group) and the conventional CT positioning three-dimensional conformal radiotherapy group (conventional CT group). In the PET/CT group, the target volume and critical organs were sketched according to PET/CT after fusion of the PET and the CT images; the treatment plan was worked out, then conventional fractionated 3DCRT ( total dosage around 40 Gy) followed by field-shrinked radiotherapy to a total dose of 65 Gy or sowas performed ;in the conventional CT group, the target volume and critical organs were sketched according to CT and 3DCRT were performed to the same total dose; All cases were treated with the TP scheme (paclitaxel 175 mg/m2,d1 ,cisplatin 40 mg,d2-4) adjuvant chemotherapy for 6 cycles after the radiotherapy. Results The followup rate was 100%. The number of patients who completed the 1-,2-and 5-year follow-up were 40,20 and 11 respectively ;The number of patients of the PET/CT group and conventional CT group were 23 and 17,11 and 9,7 and 4 respectively. Target volumes of 13 cases in the PET/CT group were changed. The complete remission and partial remission rates of the two groups were 13% 、66% and 19% 、53% (x2 = 0. 33, P =0. 564), respectively. The 1-,2-and 3-year local control rates of the PET/CT group and conventional CT group were84 % 、66% 、53 % an d72% 、59% 、44% ( x2 = 2.36, P = 0. 124 ) respectively. The1 -, 2-and 3-year survival rates were 72% 、34% 、22% and 53% 、28% 、13% (x2 =2. 46,P =0. 117) respectively. The level-1 and level-2 lungs' and trachea's late radiation injury of the PET/CT group and the conventional CT group were 28% and 53% ( x2 = 4. 14, P = 0. 042 ), respectively. The hilar and mediastinal lymph node recurrence rates of the PET/CT group were lower than those of the conventional CT group, were 3% ,25%(P = 0. 026) and 6%, 28% ( P = 0. 042 ), respectively. The main reason for treatment failure was distant metastasis both in the PET/CT group and conventional CT group,56% and 47% (x2 = 0. 56,P = 0. 453 ),respectively. Conclusions PET/CT, as a method of sketching the target of stage Ⅲ non-small cell lung cancer, can improve the radiation treatment plan, reduce the recurrence rate of hilar and mediastinal lymph nodes, meanwhile it can not improve the long-term survival rate; Distant metastasis was the main reason of failure.

Objective To explore the relationship between R time in thrombelastography (TEG) and prognosis of traumatic brain injury (TBI).Methods The data of TBI patients were collected in Fourth Peoples Hospital in Shaanxi Province from January 2015 to June 2016.The patients were divided into two groups according to the prolongation of R time at admission,and the basic data and the outcomes were analyzed.Results In basic data,Glasgow coma scale (GCS) [(9.7 ± 4.4) scores vs (12.1 ± 2.2) scores] was lower,and injury severity score (ISS) [(32.4 ± 8.9) scores vs (21.7 ± 10.4) scores],head abbreviated injury scale (AIS) [(5.0 ±0.0) scores vs (4.1 ± 1.5) scores],hemorrhage volume [(6.2 ± 5.5) ml vs (1.1 ± 1.8) ml] and mean arterial pressure[(127.2 ± 28.1) mmHg vs (103.3 ± 17.0) mmHg] were higher in the prolonged R time group.In outcomes,the in-hospital mortality (42.9％ vs 17.2％) and the rate of neurosurgical intervention (71.4％ vs 37.7％) were higher,and the duration of mechanically ventilated [(9.3 ±3.2) d vs (4.1 ± 1.7) d],ICU stay [(10.2 ± 4.4) d vs (5.6 ± 2.1) d] and hospital stay [(22.4 ± 8.1) d vs (8.3 ± 4.7) d] were longer in prolonged R time group.The Logistic regression analysis results showed that GCS ≤8 scores,ISS ＞ 25 scores and R time ＞ 10 min were the possible risk factors of hospital mortality.Conclusion TBI patients with longer R time have worse prognosis and longer R time is the possible risk factor of hospital mortality,and the prediction efficiency of R time need to be explored and validated by more research.

The kinase domain of receptor tyrosine kinase(RTK) ErbB2 was expressed fused with GFP in Pichia pastoris. Recombinant expression vector pPIC3.5K was constructed in Escherichia coli TOP10. The right P. pastoris transformants were screened on his-deficient plates and YPD-G418 plates by turns after electroporation of recombinant vector, and then induced by methanol in baffled shake bottles. The strain with highest protein yield was scaled up in a 5 L fermentor. Recombinant protein was analyzed with tyrosine kinase assay after Ni2+ affinity chromatograph. Results showed that the 100 kD recombinant protein with tyrosine kinase activity was successfully expressed in P. pastoris.

The bioreactor production of recombinant Lateolabrax japonicus growth hormone (rljGH) expressed intracellularly by Pichia pastoris was investigated. A strategy of feeding methanol at the exponential rate was established and the effect of specific growth rate on the rljGH production was examined. The results indicated that the average specific production rate increased and the rljGH production duration decreased as the specific growth rate increased. The maximum specific rljGH production (0.58 mg/g WCW) was achieved at a specific growth rate of 0.029/h. The effect of supplementing ammonium sulfate, peptone and yeast ex- tract on the rljGH production was further investigated. The results indicated that the effects of ammonium sulfate and peptone were not significant. Supplementing yeast extract of 2.5 g/L was advantageous for the rljGH production. The duration of the rljGH production was increased to 23 h from 17 h and the fermenta- tion stability of run-to-run could be improved.

A fusion expression vector pPIC3.5K-PDGFR? was constructed to express recombinant receptor tyrosine kinase PDGFR? and the right Pichia pastoris transformants were screened on his-deficient plates and YPD-G418 plates by turns after electroporation of strain GS115, a high yield strain named M3 was screened. The strain M3 was cultured in a 5 L fermentor and His-GFP-PDGFR? fusion protein was purified by Ni2+ chelating affinity chromatography. One distinct peak was obtained after elution with 250 mmol/L imidazole. Fusion protein was proved to be 90.08 kD by western blotting, and have tyrosine kinase activity by ELISA. Results showed that the receptor tyrosine kinase PDGFR? was successfully expressed in P. pastoris and could be used as a target for small molecule selective inhibitors screening.

Iron uptake mechanism of Vibrio alginolyticus was primarily investigated. V.alginolyticus could survive in the medium with high-concentration iron chelator. The strain of V. alginolyticus isolated from diseased fish produced more siderophore than that from marine environment. The extract of siderophore from V. alginolyticus could stimulate the growth of Escherichia coli mutant AN93. Under iron limitation,the growth rate was decreased and several outer membrane proteins were induced. Adding iron into the iron-limited medium the normal growth could be recovered.

Cell viability of Pichia pastoris was detected by flow cytometry (FCM) with two reagents fluorescein diacetate (FDA) and propidium iodide (PI). Compared with FDA/PI double-stained dot plots and PI single-stained dot plots,the latter could divide dead and living cells into two separate zones,and get the correct proportion. Then PI single-stained method was used to detect the change of cell viability in Pichia patoris fermentation. At glycerol batch and fed-batch phase,little dead cells were detected. At methanol fed-batch phase,cell viability decreased when cell weight increased,and was only 73.8% at 88 h.
