Objective To discuss the effects of applying electric heating pattern instrument in experimental teaching of fixed partial denture technology.Methods Totally 98 prosthodontic undergraduates of 2008 and 2009 grades were selected in this study； 46 students of 2008 grade were taken as control group and 52 students of 2009 grade were taken as experimental group.Students in experimental group made wax patterns with electric heating pattern instruments to melt inlay wax while those in control group made wax patterns with instruments heated by alcohol lamps.Teaching effects were evaluated by experimental test scores and questionnaires.Results Test scores of experimental group were (22.6± 1.8),obviously higher than those of (22.6-± 1.8) in control group (P ＜ 0.05).Satisfaction degree of experimental group were increased significantly compared with that of control group based on the resuits of questionnaire.Conclusions Applying electric heating pattern instrument in making wax patterns in experimental teaching of fixed partial denture technology is easy to operate and can improve the quality of wax pattern and working efficiency as well as enhance students' confidence,therefore it is worthy further spreading.

[Summary] The aim of this study was to examine the association between obstructive sleep apnea-hypopnea syndrome ( OSAHS ) and microalbuminuria in type 2 diabetes mellitus patients. We found that severe OSAHS significantly increases the risk of early renal damage in type 2 diabetes mellitus patients with HbA1C<7% ( lowest oxygen saturation:OR=2. 41, 95% CI 1. 19-8. 08; apnea hyponea index: OR=2. 91, 95% CI 1. 50-9. 11), suggesting that OSAHS may increase the risk for early renal damage in type 2 diabetes mellitus, especially in those with successful control of glucose.

Objective To explore the changes in cardiac index and oxygenation index in sepsis piglets after nitric oxide (NO) gas inhalation. Methods A piglet model of sepsis was induced by intravenous infusion of Gram-negative bacterial endotoxin (LPS), then the piglets were randomly divided into two groups. NO group (n=8) was administered with inhaled nitric oxide of 80ppm via volume control (VC) mechanical ventilation for one hour, while the control group (n = 4) received mechanical ventilation with VC and was observed for one hour to assess the stability of the model. The parameters of oxygenation and hemodynamics were measured by PICCO and arterial blood gas analysis every fifteen minutes for one hour. Results Injection of endotoxin induced a stable pig model of sepsis. PH, HCO3-, arterial oxygen pressure (PaO2), mean arterial pressure (MAP) and cardiac index in this model were significantly lower the baseline values (P < 0.01). Arterial oxygen pressure and cardiac index were significantly higher in N0 group than in the control group (P<0.01). Heart rate (HR), central venous pressure (CVP), global end-diastolic volume index (GEDI) and intrathoracic blood volume index (ITBI) did not significantly differ between NO group and the control group. Conclusions Inhalation of nitric oxide gas can significantly improve oxygenation and cardiac function in piglets with sepsis.

Objective To evaluate the significance of high-frequency oscillatory ventilation(HFOV) used in acute hypoxic respiratory failure(AHRF) children,failing to conventional ventilation.Methods This was a retrospective study of AHRF children ventilated by HFOV from January 2011 to September,2013.All patients were initially treated by conventional mechanical ventilation (CMV),and changed to be treated by HFOV if the patient met to one of the following criteria after the CMV parameters of PIP ＞ 30 mmH2O(1cmH2O =0.098 kPa) or PEEP ＞ 10 cmH2O with FiO2 100％ ∶ (1) SpO2 ＜ 90％ or PaO2 ＜ 60 mmHg (1 mmHg =0.133 kPa) ; (2) severe respiratory acidosis (PaCO2 ＞ 80 mmHg) ; (3) serious air leakage (mediastinal emphysema or pneumothorax).The following parameters were recorded:patient's gender,age,living PICU time,CMV ventilation time,HFOV ventilation time.We reviewed ventilation parameter settings (MAP,△P,F,FiO2),oxygenation index(PaO2/FiO2,OI),arterial blood gas,heart rate,blood pressure at different time points including late CMV(H0),2 h after HFOV(H2),6 h after HFOV(H6),12 h after HFOV(H12),24 h after HFOV (H24) and 48 h after HFOV (H48),respectively.Various indexes at different time points were compared between survival group and death group,oncology group and no-oncology group.Results PaO2 at H2 compared with H0 had significant improvement[76.9(61.9 ～ 128.0) mmHg vs 50.1 (49.5 ～68.0) mmHg,P =0.006] . PaO2/FiO2 at H2,H48 had significant improvement compared with those at H0,H24 [94.9(66.8 ～ 138.9) mmHg vs 68.0(49.5 ～86.8) mmHg,P=0.039; 135.0(77.6～240.0) mmHg vs 90.7 (54.6 ～161.7) mmHg,P =0.023)].All children's systolic pressure,diastolic blood pressure,heart rate at various time points had no difference (P ＞0.05).Compared to death group(n =14),PaO2/FiO2,OI at H6,H12,H24,H48 in survival group (n =9) had significant improvement(P ＜ 0.05).Compared to oncology group (n =10),OI at H2,H6 in no-oncology group(n =10) had significant improvement [(19.2 (13.9 ～ 26.6) vs 33.8 (19.7 ～ 48.3),P =0.049 ; 16.0(8.4 ～27.1) vs 28.9(20.9 ～38.9),P =0.027)],and mean airway pressure between two groups at H2,H6,H12 had significant improvement(P ＜ 0.05).Mortality had no significant differcence between two groups (4/10 vs 10/13,P =0.086).Conelusion HFOV used in children with AHRF which had failed with CMV ventilation can improve the patient's PaO2 and OI.Heart rate and blood pressure are stable during HFOV treatment.Oncology group patients needed higher initial MAP to improve oxygenation than no-oncology group patients when changed to HFOV treatment,but the mortality showed no difference between two groups.

Objective To investigate the common bacteria and change in antimicrobial resistance in an intensive care unit (ICU)in the past 5 years,and provide evidence for rational use of antimicrobial agents.Methods Bacteria isolated from ICU patients in a tertiary first-class hospital from 2009 to 2013 were collected,identified,and per-formed antimicrobial susceptibility testing.Results A total of 1 196 bacteria isolates were isolated in 2009-2013, the top five species were Acinetobacter baumannii (A.baumannii,29.60%),Pseudomonas aeruginosa (P . aeruginosa,14.38%),Staphylococcus aureus (S .aureus ,12.21 %),Escherichia coli (E.coli,12.21 %),and Klebsiella pneumoniae (K .pneumoniae ,11 .37%).Resistance rates of S .aureus to oxacillin,gentamycin, clindamycim,ciprofloxacin,and rifampicin showed a decreasing tendency from 2009 to 2013(all P <0.05),and no strain was detected to be resistant to vancomycin during 5 years.Resistance rates of P .aeruginosa to ceftazidime, cefepime,aztreonam,gentamycin,amikacin,tobramycin,and piperacillin/tazobactam decreased gradually (all P <0.05),imipenem resistance rates were 32.26% -46.43% in 2009 -2012 and 16.00% in 2013;A.baumannii maintained a low level resistance to amikacin,tobramycin,and compound sulfamethoxazole(all P <0.05),resistance rates to imipenem were all >80% in 2009-2011 and 10.53% in 2013,A.baumannii had high resistance rates to most antimicrobial agents(resistance rates were >80%)during 5 years.Resistance rates of K .pneumoniae and E. coli to piperacillin/tazobactam,cefazolin,cefepime,amikacin,and aztreonam had a decreased tendency in 2009 -2013(all P <0.05).Conclusion The common bacteria causing infection in the ICU of this hospital showed a down-ward trend,which may be related to the introduction of national policies and management of hospital,continuous management of antimicrobial agents is suggested,antimicrobial agents should be used rationally to prevent the in-crease of bacterial resistance.

Objective To investigate the effect of Xuesaitong injection on acute inflammatory response and preoperative cognitive dysfunction (POCD) in patients after gynecological laparoscopic surgery. Methods From July 2016 to September 2017, there were 246 patients having undergone gynecological laparoscopic surgery in the Department of Obstetrics and Gynecology of Guangyuan Central Hospital. And according to whether Xueseton was used or not preoperatively, they were divided into a control group (n = 118) and an observation group (n =128). The patients in the observation group were given intravenous drip with 400 mg Xuesaitong at 30 minutes before surgery, while the patients in the control group were given intravenous drip with equal amount of 5% glucose solution at 30 minutes before surgery. The enzyme-linked immunosorbent assay (ELISA) was used to detect serum levels of interleukin-1 and -6 (IL-1, IL-6) and tumor necrosis factor-α (TNF-α); the neuropsychological tests were used to assess the patients' cognitive function; visual analogue scale (VAS) score was applied to assess the postoperative pain of patients; the intra-operative situation and the postoperative related risk occurrence were recorded in the two groups. Results The comparisons of indicators between the observation group and control group were as follows: the operation time (minutes: 106.2±30.6 vs. 114.6±22.7), anesthesia time (minutes: 126.1±21.2 vs. 122.1±25.3), intra-operative blood loss (mL: 324.4±63.1 vs. 313.6±65.1) and postoperative rash (1 case vs. 2 cases), chest distress (11 cases vs. 8 cases), palpitation (10 cases vs. 8 cases), asthma (5 cases vs. 4 cases), hematuria (2 cases vs. 3 cases), incision bleeding (4 cases vs. 3 cases), lower limb deep venous thrombosis (DVT: 11 cases vs. 14 cases) and VAS score (3.6±0.9 vs. 3.8±0.8), prothrombin time [PT (s): 10.7±2.2 vs. 9.7±1.5], activated partial thromboplastin time [APTT (s): 30.3±3.3 vs. 30.7±4.3], international normalized ratio (INR: 0.9±0.1 vs. 1.1±0.1), all of the above comparisons in indexes between the two groups had no statistical significant differences (all P > 0.05); with prolonged treatment, the IL-1, IL-6 and TNF-α levels were gradually decreased in two groups, reached the lowest levels at 12 hours after surgery, and the changes in the observation group were more significant than those in the control group [IL-1 (pg/L): 3.8±1.0 vs. 6.5±1.2, IL-6 (pg/L): 6.3±1.3 vs. 10.3±1.6, TNF-α (pg/L): 5.6±1.3 vs. 8.4±1.2]; after surgery the scores of MMSE test (score: 25.8±3.1 vs.20.8±3.3) and the word fluency test (14.9±1.8 vs. 12.8±1.8) in the observation group were significantly higher than those in the control group, while the incidence of POCD was significantly lower than that in the control group [18.7% (24/128) vs. 33.8% (40/118), all P < 0.05]. Conclusion The use of Xuesaitong before gynecological laparoscopic surgery can reduce the patients' expression levels of serum IL-1, IL-6 and TNF-α at acute inflammatory stage, reduce the occurrence of POCD and does not increase the related risk after surgery.

Erythroderma with complicated etiology is one of the severe skin diseases and has high mortality,of which the incidence was 0.5％-1.5％ in skin diseases.Erythrodermic psoriasis (EP) is the commonest type of erythroderma.In addition,there are drug-induced erythroderma,erythroderma secondary to preexisting dermatoses,malignancy-related erythroderma,and idiopathic erythroderma of unknown etiology.Erythroderma of different etiologies has various clinical manifestations,resulting in relevant curative effects and outcomes.In this article,we retrospectively investigated 205 erythroderma patients about clinical symptoms,auxiliary examination and treatments,and evaluated the efficacy and prognosis.There were 84 cases of EP among 205 patients,10 cases of erythroderma caused by specific drugs,77 cases of erythroderma secondary to preexisting dermatoses (excluding psoriasis),7 cases of erythroderma patients suffering from malignancy and 27 cases with unknown causes.We concluded that the etiology of male patients in different age groups had significant difference.The incidence of EP was the highest among all types.The EP was commonly accompanied with hypoproteinemia,and changed into psoriasis vulgaris after treatment.Drug-induced erythroderma was commonly accompanied with fever,and mostly cured by systematic steroid therapy.For erythroderma secondary to preexisting der matoses,the original dermatoses must be actively treated to achieve a satisfying prognosis.Erythroderma with malignancy or unknown causes had long-term duration,poor response to the treatment,and high potential to relapse.Therefore,clarifying the etiology,providing an appropiate and individual regimen,and regular follow-up are crucial for the successful treatment of erythroderma with unknown causes.

OBJECTIVETo compare the thermal conductivity of the related tissues along meridian line and non-meridian area.

METHODSForty healthy volunteers were observed with a infrared thermal imaging system.

RESULTSDuring heating the acupoint or the non-acupoint along the meridian line, the velocity of spreading of the temperature-increasing response along the meridian line was more easy and rapid, with a definite direction. However, during heating the non-meridian spots, the change of temperature was confined to the local area, with no definite direction. The spreading of skin temperature response along the meridian line was more rapid than the non-meridian area during both the two were heated simultaneously, and finally, 3 infrared radiant tracks along the meridian courses conformed basically with that of the classical three yin- meridians of the hand appeared.

CONCLUSIONThe thermal conductivity of the related tissues along the meridian line is better than that of non-meridian area and has definite direction, with differences in physical characteristics between them.

In order to make clear the packing mechanism of the BmNPV polyhedra, a polyhedrin gene negative recombinant baculovirus, vBmBac(polh-)-5B-EGFP, expressing EGFP was constructed, and used to infect BmN cells jointly with wild-type BmNPV. Fluorescent microscopic observation demonstrated that EGFP and polyhedrin were expressed simultaneously, and the EGFP expression and polyhedra formation occurred in most of the jointly infected cells. Analysis of the purified polyhedra from jointly infected BmN cells showed that the foreign proteins were present in the polyhedra. The results indicated that BmNPV polyhedrin could incorporate proteins other than viral proteins into the polyhedra. It implies that a nonspecific recognition mechanism exists in the embedment of BmNPV polyhedra.
