To investigate the gene typing, molecular characteristics of virulence and resistance associated gene of Clostridium difficile from clinical isolates in China, the genes tcdA,tcdB of toxin A and B, cdtA,cdt B of binary-toxin, and erm B of clindamycin resistance were detected by conventional PCR. Genotyping of toxic C. difficile were conducted by means of analysis of 16s-23s internal spacer region polymorphism with PCR assay. Then the antibiotic resistance of toxic C. difficile to ampiciline, clindamycin, metronidazole and vancomycin was conducted with E-test. It was found that 8 toxic C. difficile strains were demonstrated out of 12 clinical isolates, in which 5 strains were tcdA+ and tcdB+, and 3 strains tcdA- and tcdB+, accounting for 62.5% and 37.5% respectively. Binary-toxin genes detection were negative in all the strains. Clindamycin resistance associated gene ermB was positive in 4 out of 8 toxic C. difficile strains, accounting for 50%. 8 toxic isolates were typed into 4 gene types, the dominant type was ZR I,accounting for 62.5%. Resistance rate of 8 toxic C. difficile strains against ampiciline(AC), clindamycin(CM), metronidazole(MZ) and vancomycin(VA) was 37.5%,87.5%,12.5%, and 0 respectively. No isolates belonged to ribotype 027 or 078. Isolation rate of toxic C. difficile is high to 66.7%. There is obvious gene polymorphism in clinical isolates of Chinese toxic C.difficite, and ZR I is preponderant genotype in 4 genotypes. C. difficile shows some resistance to ampiciline, clindamycin, metronidazole, but susceptive to vancomycin.

ObjectiveTo evaluate the feasibility of using dexmedetomidine (Dex) as supplement to stellate ganglion block (SGB) in the treatment of trigcminal post-herpetic neuralgia in elderly patients.MethodsForty-five ASA Ⅱ patients with trigeminal post-herpetic neuralgia aged 65-85 yr weighing 45-85 kg undergoing stellate ganglion block were randomly divided into 3 groups ( n =15 each): group SGB; group Dex 0.4 and 0.6 μg/kg +SGB (groups DS1 and DS2).SGB was performed on the affected side with 0.5％ ropivacaine 8-10 ml.Dex 0.4 and 0.6 μg/kg in normal saline were infused iv over 15 min before SGB in groups DS1 and DS2 respectively.The onset time and duration of block were recorded.Bradycardia,hypotension and respiratory depression were also recorded.The intensity of pain was assessed with VAS scores (0=no pain,10 =worst pain) before and at 1,2,4,8 weeks after SGB.VAS score ≤3 was defined as satisfactory analgesia.The rate of satisfactory analgesia was calculated.ResultsThere was no significant difference in the incidence of bradycardia,hypotension and respiratory depression among the 3 groups.The duration of block was significantly longer and the rate of satisfactory analgesia at 2,4,8 weeks after SGB was significantly higher in groups DS1 and DS2 than in group SGB.There was no significant difference in the onset time,duration of block and the rate of satisfactory analgesia between groups DS1 and DS2.ConclusionSGB with Dex has better therapeutic effect than SGB in elderly patients with trigeminal post-herpetic neuralgia.

Objective To characterize the association of adiponectin,leptin and free fatty acids(FFA)with adiposity,insulin resistance,lipid profiles and inflammatory markers in type 2 diabetes.Methods We measured fasting serum adiponectin,leptin,FFA,high-sensitive C reactive protein(hs-CRP) levels and metabolic parameters in 77 cases of type 2 diabetic patients with or without obesity and 26 healthy subjects.Results Following parameters were significantly higher in type 2 diabetic patients than in healthy subjects: fasting serum leptin(?g/L)(4.5?3.9 vs 4.1?2.1),hsCRP(mg/L)(0.69?1.07 vs 0.33?0.47),FFA(?mol/L)(566?227 vs 391?129) and triglyceride(mmol/L)(1.61?1.02 vs 1.01?0.40);however,following parameters were significantly lower in type 2 diabetic patients than in healthy subjects: serum adiponectin(mg/L)(5.5?3.4 vs 9.1?4.1),highdensity lipoprotein cholesterol(HDL-C)(mmol/L)(1.22?0.27 vs 1.48?0.26), apolipoprotein AI(mmol/L)(1.35?0.19 vs 1.49?0.18) and apolipoprotein AII(mmol/L)(0.29?0.07 vs 0.34?0.06) concentrations(P

Sixty gynecological patients undergoing laparoscopic surgery during October 2010 to June 2011were randomly divided into 2 groups:laryngeal mask airway proseal ( PLMA group,n =30 ) and laryngeal mask airway classic (CLMA group,n =30).Laryngeal mask was inserted after induction.The heart rate (HR),mean arterial pressure (MAP),airway sealing pressure,the average time of placement,the pulmonary satisfaction and complications were recorded.There was no significant difference in heart rate and MAP between the two groups(P＞0.05).The airway sealing pressure [ (26 ±6) cm H2O ( 1cm H2O =0.098 kPa) vs.(16±5) cm H2O],the average time of placement [(36±5) vs.(24±6) s)] and the excellent lung ventilation(90％ vs.73％ ) in the PLMA group were more significantly increased than those in the CLMA group(P ＜0.05).PLMA can assure good airway sealing and is more suitable for gynecological patients undergoing laparoscopic surgery.

Objective:To investigate the relationship between T/N take-up value and the clinic feature of breast cancer, and explore the predictive ability of T/N take-up value for breast cancer prognosis.Methods:Breast cancer patients treated at Zhongshan Hospital, Fudan University and undergoing BSGI examination before surgery from Jan 2014 to Nov 2018 were collected. The relationship between T/N take-up value and the clinical features of breast cancer and DFS was analyzed.Results:A total of 419 breast cancer patients were collected. The median follow-up time after operation was 34 months. At the end of the follow-up, 43 cases relapsed and 376 cases did not. The average T/N values of CC position and MLO position before surgery were 2.74 and 2.58. The T/N value of CC is related to tumor stage (χ 2=22.077, P<0.05), lymph node metastasis ( Z=2.138, P<0.05) and degree of invasion ( Z=3.371, P<0.05). The T/N value of MLO is related to tumor stage (χ 2=23.091, P<0.05), lymph node metastasis ( Z=2.531, P<0.05) and degree of invasion ( Z=2.99, P<0.05). The best cut-off values of CC position and MLO position calculated by ROC curve are 2.59 and 2.97. Univariate analysis showed that tumor staging ( HR: 2.039, 95% CI: 1.404-2.962, P=0.001), T/N value at CC position ( HR: 4.349, 95% CI: 2.141-8.883, P<0.001) and T/N value at MLO position ( HR: 2.767, 95% CI: 1.520-5.039, P<0.001) is an independent risk factor for the prognosis of breast cancer. Multivariate COX regression analysis showed that tumor stage ( HR: 1.959, 95% CI: 1.302-2.946, P=0.001) and T/N value at MLO position ( HR: 3.498, 95% CI: 1.531-7.992, P=0.003) are independent risk factor of breast cancer prognosis. Conclusion:The BSGI T/N value has a certain correlation with breast cancer DFS.

Objective To evaluate the myocardial protective effect of dexmedetomidine in the pediatric patients undergoing total correction of tetralogy of Fallot.Methods Forty ASA physical status Ⅱ] or Ⅲ pediatric patients of both sexes,aged 9 months-5 yr,weighing 7-21 kg,scheduled for elective total correction of tetralogy of Fallot under cardiopulmonary bypass,were randomly divided into 2 groups (n =20 each):control group (C group) and dexmedetomidine group (D group).Anesthesia was induced with iv injection of midazolam,sufentanil,etomidate and rocuronium.The patients were endotracheally intubated and mechanically ventilated.After intubation,dexmedetomidine was infused intravenously at 0.6 μg· kg-1 · h-1 until the end of operation in group D,while the equal volume normal saline was given instead of dexmedetomidine in group C.Venous blood samples were obtained before operation,at the end of operation and at 24 h after operation for determination of plasma TNF-α and IL-6 concentrations.The occurence of anoxic spells was recorded.Results The concentrations of plasma TNF-α and IL-6 were significantly lower at the end of operation and 24 h after operation in group D than in group C(P ＜0.05).The incidence of anoxic spells was 0 in group D,however it was 20％ in group C.Conclusion For the pediatric patients undergoing total correction of tetralogy of Fallot under cardiopulmonary bypass,dexmedetomidine infused at 0.6 μg· kg-1 · h-1 during operation can exert myocardial protective effect with clinical significance.

Objective To evaluate the effects of blood-lipid report's reformat on outpatients' behavior and knowledge of dyslipidemia therapy.Methods The blood-lipid report was reformatted by adding three tables from the Chinese Guideline on the Prevention and Treatment of Adult Dyslipidemia on its back.The same questionnaire was used twice to evaluate the patients' behavior and knowledge of dyslipidemia therapy before and after reformat.Results Before and after reformat,the rates of correct deterination of their own risk stratification were 26.0％ ( 112/430 ) and 26.3％ ( 115/438 ) respectively.The awareness rates of Different LDL-C goals among different persons wcre 37.0％ (159/430) and 35.8％ (157/438).Only 0.7％ (2/306) and 1.0％ (3/299) of patients knew their blood lipid goals (P =0.557).When the report showed normal blood lipid levels,the percentages of taking lipid-lowering drug were 47.6％ ( 230/483 ) and 46.6％ ( 216/464 ),20.5％ ( 99/483 ) and 19.0％ ( 88/464 ) of patients questioned the prescription.Non-medication rates were 31.9％ ( 154/483 ) and 34.5％ ( 160/464 ) respectively before and after reformat ( P ＞ 0.05 ).For patients requiting lipid-lowering drug therapy by the guideline,treatment rate improved significantly in the low-risk group (13.3％ vs.75.0％,P =0.002).Treatment rate slightly increased in the high-risk and very high-risk groups after reformat (54.0％ vs.56.8％,62.4％ vs.69.0％,P ＞ 0.05 ).Rates of achieving lipid goal showed no change [ 41.5％ ( 102/ 245 ) vs.44.5％ ( 114/256 ),P ＞ 0.05 ] after reformat,especially among the very high-risk patients [17.9％(12/68) vs.21.6％(11/52),P＞0.05].Conclusions The blood-lipid report reformat did not improve the patient behaviors and knowledge of the prevention and treatment of dyslipidemia because of poor treatment rate and medication compliance.The combination of patient education and thorough blood-lipid report reformat may help to increase the attainment rate of dyslipidemia therapy.
