Objective To investigate the effects of lidocaine throat surface anesthesia on hemodynamics in patients with surgical operation. Methods From January 2013 to April 2016, 118 cases of patients with upper abdominal surgery in our hospital, were randomly divided into observation group (n=68) and control group (n=50), the observation group were given lidocaine throat surface anesthesia, the control group did not give the throat surface anesthesia, observed two groups before induction of anesthesia (T0), before intubation (T1) and after 1 min (T2), 5min (T3) and 10min (T4) intubation, heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) and other indicators.Results The observation group T1 and T2 SBP, DBP, MAP were significantly lower than control group (P<0.05);observation group SBP at T4 was lower than control group (P<0.05);HR of observation group and control group was not statistically significant at each period;The incidence of cough and cough classification in observation group were 22.06% and (1.20 ±0.73), which were significantly lower than that of control group 58.00%and (3.18 ±0.57)(P<0.05).The observation group and the control group breathing recovery time and the time of opening eyes difference had no statistically significant.Conclusion The surface of lidocaine anesthesia can reduce the cardiovascular response to tracheal intubation in patients with surgery and postoperative cough.

Objective To analyze the therapeutic outcomes and adverse effects of high-dose intravenous immunoglobulin (hd-IVIg) in the treatment of some severe skin diseases (toxic epidermal necrolysis, drug hypersensitivity syndrome, connective tissue disease, autoimmune bullous disease, acute graft-versus-host disease). Methods Twenty-five cases of severe skin diseases were treated with hd-IVIg (0.4 g/kg/day for a course of 5 days). Results The therapeutic outcomes were different from each other. Of all the cases, 21 improved, especially those of acute onset of toxic epidermal necrolysis and drug hypersensitivity syndrome; 1 adult dermatomyositis and 2 elder bullous pemphigoid were not relieved. A patient with acute graft-versus-host disease died. Three patients presented with minor adverse effects (headache and blood pressure rising). Conclusions hd-IVIg is effective and safe in the treatment of some severe skin diseases. More importantly, it has a substantial effect on shortening disease course and decreasing the dosage of glucocorticoids and immunosuppressants as well as on preventing infections.

Objective To study the resistance mechanism of Ureaplasma urealyticum (Uu) to erythromycin.Methods The susceptibility of 73 clinical isolates of Uu to erythromycin was evaluated by using broth dilution techniques. PCR and DNA sequencing were carried out to screen hot spot mutations at the variable region of 23S ribosomal RNA in erythromycin-resistant strains of Uu. Moreover, erythromycin resistance methylase genes (ermA, ermB, ermC) and efflux pump genes (mefA/E, msrA/B, mreA) were screened by using PCR with specific primers. Results There were 35 (47.95%) resistant Uu strains out of the 73 isolates, and the minimal inhibitory concentration varied from 8 to 32 mg/L among these resistant strains. The ermB gene was detected in 19 (54.29%) resistant strains, and msrA/B gene in 9 (25.71%) resistant strains. Two resistant strains harbored both ermB gene and msrA/B gene. No mutation at 23S ribosomal RNA or amplification of resistance-associated genes was noted in sensitive or reference strains of Uu. Conclusion The ermB and msrA/B genes may be responsible for the erythromycin resistance of Uu.

Objective To explore the efficiency of continuous glucose monitoring system(CGMS) and blood glucose self-monitoring (SMBG)in evaluating blood glucose excursion in type 1 diabetes mellitus (T1DM) complicated with pregnancy. Methods Twenty-five patients having suffered from T1DM complicated with pregnancy were selected randomly during June 2012 to July 2015. All subjects underwent blood glucose monitoring by CGMS and SMBG for 72 h, including the data of blood glucose before meal, 2 h post-meal blood glucose (2hBG) and blood glucose at 2:00 AM. Results The level of the highest blood glucose in CGMS was significantly higher than that in SMBG:(10.60 ± 2.11) mmol/L vs. (7.50 ± 1.18) mmol/L, P<0.01. The level of the lowest blood glucose in CGMS was significantly lower than that in SMBG:(3.60 ± 1.06) mmol/L vs. (4.50 ± 1.15) mmol/L, P<0.01. The level of mean blood glucose in CGMS and SMBG had no significant difference:(7.20 ± 1.18) mmol/L vs. (7.30 ± 1.15) mmol/L, P>0.05. The rate of hypoglycemia(blood glucose<3.3 mmol/L) in CGMS was 4.6%, and in SMBG was 1.9%. Through adjusting the treatment by CGMS, the blood glucose before meal, 2hBG and blood glucose at 2:00 AM at 49-72 h were significantly lower than that at 0-24 h (P<0.05). Conclusions Compared with SMBG, CGMS has a relatively larger blood glucose monitoring range and can sensitively evaluate blood glucose excursion, CGMS provides a scientific basis to develop a more rational and effective strategies for controlling diabetes.

Objective To study the ability of standard strain and clinical isolates of Ureaplasma spp. to form biofilms in vitro and to compare the antibiotic susceptibility of sessile cells and their planktonic counterparts. Methods A total of 21 Ureaplasma wealyticum(Uu) isolates recovered from female patients diagnosed with cervicitis and Uu serovar 3 and Uu serovar 8( Uu3, Uu8) were included. Scanning electron microscope and confocal scanning laser microscopy were used to identify biofilm formation. Conventional antibiotic susceptibility tests and biofilm susceptibility assays for tetracycline, erythromycin and ciprofloxacin were carried out. The paired rank sum test and was applied to analyze the statistical differences between the MIC and the minimal biofilm inhibitory concentration. The x2 test was applied to analyze the statistical differences of global resistance percentages between planktonic cells and sessile cells. Results Uu3, Uu8 and 21 Uu isolates all can form biofilms in vitro. Minimal inhibitory concentration of sessile cells compared with planktonic cells were obviously higher for tetracycline, erythromycin and ciprofloxacin (P <0.001). Global resistance percentages between planktonic cells and sessile cells were different for erythromycin (9.52% vs 61.90% , P < 0. 001), ciprofloxacin ( 80. 95% vs 100% , P = 0. 035 ) and tetracycline (4. 76% vs 14.29% , P =0.293). Conclusion Uu isolates and Uu1, Uu8 all can form biofilms in vitro, and biofilm formation can strengthen resistance of Uu to antibiotics, even multidrug resistance was observed.

Objective To investigate the role ofglutamic acid decarboxylase autoantibody(GAD-Ab)and protein tyrosine phosphatase autoantibody(IA-2A) in postpartum follow-up of gestational diabetes mellitus (GDM).MethodsGAD-Ab,IA-2A,insulin and glucose metabolism index were measured in 82subjects with normal glucose tolerance (control group) and 84 patients with GDM(GDM group) during 24 to 28 weeks in pregnancy,postpartum 6 to 12 weeks and 2 years.GDM group was divided into antibodies positive group (GAD-Ah or IA-2A were positive) with 18 cases and antibodies negative group (GAD-Ab and IA-2A was negative) with 66 cases.Results Homeostasis model insulin resistance index (HOMA-IR) in GDM group was higher than that in control group (3.87 ± 2.17 vs.2.31 ± 0.52,P ＜ 0.05 ).Homeostasis β -cell function index (HBCI) and 30 min net increment of insulin/30 min net increment of glucose ( △ I30/△ G30) in GDM group were lower than those in control group[206.38 ± 138.06 vs.422.43 ± 228.93 and (20.16 ±11.38) mU/mmol vs.(26.54 ±24.30) mU/mmol,P ＜0.05].The numbers who had the family history of diabetes mellitus and the used of insulin for treatment in antibodies positive group were higher than those in antibodies negative group[ 83.3％ (15/18) vs.28.8％ (19/66) and 77.8％ ( 14/18 ) vs.30.3％ (20/66) ],HOMA-IR,△ I30/ △ G30 and HBCI in antibodies positive group were lower than those in antibodies negative group [3.20±0.84 vs.4.02±0.36,(16.81 ±2.91) mU/mmol vs.(21.55± 11.11) mU/mmol and 124.95 ± 5.03 vs.217.43 ± 115.64,P＜ 0.01 ].Fasting plasma glucose (FPG),2 hours postprandial glucose (2hPG)and glycosylated hemoglobin (HbA1c) in antibodies positive group were higher than those in antibodies negative group during postpartum 6 to 12 weeks and 2 years [postpartum 6 to 12 weeks: (8.20 ±3.11)mmol/L vs.(5.39 ±0.76) mmol/L,(15.22 ±7.29) mmol/L vs.(8.15 ± 1.93) mmol/L,(7.26 ± 1.04)％ vs.(5.88 ±0.41)％ ;postpartum 2 years: (8.91 ±2.80) mmol/L vs.(4.93 ±0.66) mmol/L,(15.75 ±7.87)mmol/L vs.(7.85 ± 1.79) mtmol/L,(7.18 ± 1.22)％ vs.(5.64 ± 0.32 )％,P ＜ 0.01].△ I30/ △ G30 and HBCI were significantly decreased in antibodies positive group postpartum 2 years.No change of the above parameters in antibodies negative group was found.The occurrence rate of type 1 diabetes mellitus (T1DM) was 16.7％(3/18) and 33.3％(6/18) postpartum 6 to 12 weeks and 2 years in antibodies positive group,there was no T1DM in antibodies negative group.ConclusionsWomen with GDM are partly associated with T1DM.Requiring insulin therapy during pregnancy and GAD-Ab or IA-2A positive have considerable risk for developing T1DM.It is also an important predictor to GDM after parturition.

OBJECTIVETo investigate the value of application of mandibular outer cortex as bone graft by comparing its bone absorption with cranial outer cortex.

METHODS8 minitype grown-up pigs at the age of 8 - 12 months underwent surgery of taking out the same size (2.5 cm x 1.0 cm) of outer cortex from mandible and craninium. The volume of the outer cortex was measured by volume-displacement method. Then the outer cortex of mandible and cranium were onlay grafted to the each side of the pig snout, respectively. 12 weeks later, 2 pigs were randomly selected for histological examination. The other 6 pigs were killed 24 weeks after surgery for measurement of the bone graft volume and histologic examination.

RESULTSThe bone graft absorption rate was (41 +/- 5)% for mandibular outer cortex and (46 +/- 12)% for cranial outer cortex, showing no significant difference between them (P = 0.51). The histologic examination results also had no marked difference in the bony healing and reforming between the two graft.

CONCLUSIONSMandibular outer cortex is a good donor site for onlay bone graft in craniofacial region.

Lonicerae Japonicae Flos was one of the most widely used traditional Chinese medicine for its special biological activities. The content of luteoloside, one of its major compounds, was an important standard for the quantity control of Lonicerae Japonicae Flos. The major method used for the detection of luteoloside was instrumental analysis. Compared with the ELISA method, instrumental analysis was time-consuming, complex pretreatment and low-throughout. Thus, it was significantly important to develop an enzyme-linked immunosorbent assay (ELISA) for luteoloside analysis. Here, the conjugates of luteoloside-bovine (LG-BSA) and luteoloside-ovalbumin (LG-OVA) were produced as the immunogen and coating antigen by the carbodiimide ( CDI) method, respectively. The conjugation ratio of carrier protein and the hapten in the conjugate were determined by UV-Vis spectrophotometry (UV). LG-BSA conjugate was used to immunize Bal b/c mice to produce antiserum. The titer and specificity of antiserum were detected by ELISA. The conjugation ratio of hapten and carries protein were 3. 7: 1 (LG-BSA) and 1. 0: 1 (LG-OVA). The antiserum titer was higher than 2 000 with the linear range of 18.4-4 852.4 μg x L(-1), R2 = 0.988 4 and IC50 = 298.7 μg x L(-1). The result showed that the conjugate antigen LG-BSA was synthesized successfully and the mice can produce specific antiserum injected with artificial antigen.
