Objective To develop an intelligent assist order system for parenteral nutrition and embed it into hospital information system,so as to facilitate rational prescription of parenteral nutrition.Methods Comprehensive database,knowledge base and control system of parenteral nutrition orders were set up based on production rule.An intelligent assist order system for parenteral nutrition was designed and developed.Individual energy demand of patients were calculated automatically and compared with doctors' orders of parenteral nutrition.Cation concentration was calculated automatically and controlled for the stability of all-in-one parenteral nutrition admixture.Results This system achieved successful and fast calculation of individual energy demand,over-standard warning of total energy,the ratios of carbohydrates to lipids and non-protein calories to nitrogen,ion concentration,and liquid volume.It also controlled the cation concentration,thus avoiding demulsification.Conclusions The intelligent assist order system for parenteral nutrition can solve the problems of energy calculation and ensure the stability of all-in-one parenteral nutrition admixture.As a result,it can improve the utilization of parenteral nutrition in hospital.

OBJECTIVETo investigate the clinical application of pedicled superficial circumflex iliac artery (SCIA) flaps in Burns and Plastic Surgery.

METHODS19 cases with skin and soft tissue defects were repaired with the Superficial circumflex iliac artery flaps. The defects located in the hand and forearm, the lower abdomen and perineal area, the radicle area of thigh, etc. Before the SCIA flaps were transfered to the recipient areas, 15 cases with different kinds of wounds were debrided thoroughly, 3 cases with scar were removed directly. The size of the flaps ranged from 3.0 cm x 4.5 cm to 26.0 cm x 22.0 cm, and the pedical was 5 cm to 7 cm in length.

RESULTSThe flaps in the 18 cases survived completely. Skin necrosis in the distal end of the flap appeared in 1 case, and the wound healed after the second repair. The follow-up period rang from 3 to 18 months. The apperance and function of the hand or foot was satisfactory.

CONCLUSIONSBecause the pedicled SCIA flaps can be obtain conveniently and contain sufficient blood-supply, so the flap is easy to survive and the flap can be designed in a large size. We believe it is an ideal method to use this flap to repair skin and soft tissue defects located in hands, forearms, the lower abdomen and perineal areas, the radicle area of thigh and so on.

Objective To evaluate the value and the expression of Axl receptor tyrosine kinase (AxlTK) in renal pathology of lupus nephritis (LN) patients. Methods The expression of AxlTK were detected in 29 LN and 10 primary nephritic syndrome (NS) patients using immunohistochemistry in renal tissue. The correlations between the levels of AxlTK on glomeruli and clinical manifestations, laboratory parameters, disease activity, and renal pathology in LN patients were investigated. T test and single factor analysis of variance were used tp compare between groups, and Pearson or Spearman test was used for correlation analysis. Results AxlTK was extensively expressed on surface of mesangial cells, endothelial cells in glomeruli. There was more expression of AxlTK on mesangial cells in LN patients [(7.0 ±2.2)×10-2] than that in primary NS patients [(3.1 ±1.2) ×10-2] (t=5.382, P<0.01). The expression of AxlTK in the glomeruli of LN patients with oral ulcers is higher than that in patients without of ulcers (t=2.259, P=0.032), and it was positively correlated with the anti-nucleosome antibody (AnuA) level in patients (r=0.488, P=0.017). The expression of AxlTK on glomeruli were higher in class Ⅳ and classⅢ of LN patients than that of class Ⅴ, but there was no statistically significant difference between them (P>0.05). Conclusion The expression of Axl TK in glomerular is significantly increased in glomeruli in LN patients. The expression level of AxlTK on glomeruli is correlated with the occurrence of oral ulcers and AnuA. The level of AxlTK expression is related to pathological categories of kidney in LN patients. The results of this study suggest that AxlTK might participate in the pathogenesis of LN.

Objective To compare the effects of equivalent dose sufentanil,remifentanil or fentanyl on hemodynamic and cardiac output in the elderly patients during induction of general anesthesia.Methods Ninety elderly patients(ASA Ⅰ ～ Ⅱ) undergoing elective abdominal surgery under general anesthesia were randomly divided into sufentanil group(group S),remifentanil group(group R) and fentanyl group(group F),30 patients in each group.Patients in group S,group R and group F received sufentanil 0.2μg/kg,remifentanil 2μg/kg and fentanyl 2μg/kg Ⅳ,respectively,using an blind method before intubation.SBP,DBP,MAP,HR,CO,CI and SVR were recorded before of anesthesia (T0),immediately after induction (T1),1,3 minutes after tracheal intubation (T2,T3).Changes of SBP and HR during observation were also recorded.Results The MAP and HR in three groups at T1 were significantly lower than those at T0 and decreased significantly in group R than those in group F and S(P ＜0.05).The MAP and HR in group F significantly increased at T1 than T0.The MAP and HR in group R were significantly decreased after tracheal intubation.Compared with the baseline,the MAP and HR in group S at T1,T2,remained unchanged.In group R,there were two patients whose HR were under 50 bpm.In group F,the MAP at T1,T2 were significantly higher than those at T.In group S,there were no significant changes in CO,CI,SVR which were all within normal range (P ＞ 0.05).Conclusion Both sufentanil and remifentanil effectively inhibit the stress response during induction of general anesthesia.At the same time,sufentanil has better hemodynamic stability.

Objective To evaluate the respiratory mechanics and inflammatory status in elderly patients with stable chronic obstructive pulmonary diseases (COPD).Methods The arterial blood gases (ABGs),respiratory drive and its derivatives,mechanics of respiratory muscles,resistance and compliance of airway,interleukin-8 (IL-8)and interferon-?(IFN-?)were measured in 42 cases withstable COPD and 40 subjects of normal control.Results The elderly patients with stable COPD had great changes in the following parameters while compared with the control group:peak inspiratory pressure(PIMAX) [(4.48?2.11)vs(6.10?2.91)kPa],maximum expiratory pressure (PEMAX)[(6.30?3.20)vs(9.15?93.30)kPa],0.1s mouth occlusion pressure(P_(0.1)) with its correction index,airway resistance,compliance,ABGs,the levels of IL-8[(218.46?91.14) vs (161.84?14.40)ng/L]and IFN-?[(2435.82?639.92)vs(1652.40?95.08)ng/L],which might aggravate the progress of COPD consistently.Conclusions The elderly patiends with stable COPD has marked changes in respiratory drive,airway resistance,and airway compliance,respiratory mechanic and inflammatory status.The intervention should be performed in the elderly stable COPD patients.

Objective To explore the operational methods and effect of craniopharyngioma resection via fronto-basal interhemisheric approach. Methods The clinical data of 31 patients who had underwent craniopharyngioma resection via fronto- basal interhemisheric approach were analyzed retrospectively. Results The saddle area structures of all the 31 patients were revealed well. The tumor total resection was in 19 cases (61.3%), and the tumor subtotal resection was in 12 cases (38.7%). The vision and field of vision after surgery were improved. Six cases (19.4% ) presented electrolyte disturbance, and 15 cases (48.4%) presented diabetes insipidus. Conclusions The fronto-basal interhemisheric approach can clearly expose the anatomical structures in midline and saddle area. This approach is safe and effective for craniopharyngioma resection.

Objective To study the efficacy and safety of CO2 laser microsurgery for early glottis carcinoma.Methods The data of 96 cases of early glottic laryngeal carcinoma treated with CO2 laser microsurgery were retrospectively analyzed.Surgical specimens were conventionally embedded with paraffin and serially sectioned.Sections were stained by using hematoxylin-eosin for pathologic examination.The local control rate was observed after operation.Results Among the 96 specimens,88 surgical margins were negative and 8 were positive.10 patients (10.4 ％) recurrenced followed up for 3 years.The recurrence rates of Tis,T1a,T1b and T2 were 0 (0/10),4.1％ (2/48),25.0 ％ (4/16) and 18.1％ (4/22),respectively,with significant differences among groups (X2 =6.105,P ＜ 0.05).All of 8 cases with positive margin and 2 cases with negative margin were recurrened.The recurrent rate of patients with involvement of the anterior commissure was 30.0 ％ (6/20),which was higher than that of patients with no tumor invasion [5.3 ％ (4/76)] (X2 =9.624,P ＜ 0.01).Conclusions The safe edges can be obtained by CO2 laser microsurgery for early stage of glottis carcinoma,which have advantages in local control rate,vocal function of the larynx and curative effect.

To develop an ophthalmic preparation of Shedan, an in situ forming gel was prepared with the formulation containing 18% of poloxamer 407 and 5% of poloxamer 188 by response surface designs plus central composite designs. The rheology results showed that LVE range gamma should limited within 0.5%, Shedan high-frequency region, and the thixotropy recovery time is less than 5 seconds. The phase transition temperature was 33.25 °C according to curve of storage modulus and loss modulus determined by temperature scanning. Surface tension and osmometer of it determined by surface tension meter and dew point osmometer were 36.43 mN · m(-1), and 320.6 mOsm · kg(-1), respectively. Fluorescein sodium was selected as the marker to monitor the corneal residence time, and the results showed that Shedan gel could prolong drug residence for 180 min. In line with zero-order kinetics, releases of muscone and salvianolic acid B in vitro depends on gels erosion. The results of rabbit ocular irritation experiments suggested that Shedan in situ forming gel was biocompatible and nonirritant. In conclusion, a novel Shedan in situ forming gel was developed and characterized for potential drug treatment of retinal vein occlusion.
