Objective To explore the relationship between plasma cholesterol ester transfer protein(CETP) and TaqIB gene polymorphism and type 2 diabetes mellitus(DM).Methods The genotypes of the first intron of CETP TaqIB gene in 102 patients with type 2 DM and 103 healthy controls were analyzed by polymerase chain reaction-restricted fragment length polymorphism(PCR-RFLP),and plasma CETP were measured by enzyme-linked immunosorbent assay(ELISA).The association of gene polymorphism with plasma lipids,lipoproteins and apolipoproteins was also analyzed.Results No significant differences in both of the alleles frequencies and genotypes in type 2 DM were noted in comparison with controls.There were no relationships between CETP TaqIB gene polymorphism and gender,family history,smoking and body mass index(BMI).No significant differences of plasma lipid levels were observed in healthy controls with different genotypes.However,significant differences in level of HDL-C or apoAI among different CETP TaqIB genotype groups were observed,and significant correlation between low high-density lipoproteinemia and B1 allele in type 2 DM was observed.Conclusion CETP TaqIB gene polymorphisms associated with lipid metabolism,which may be an important genetic factor for abnormal lipid metabolism in type 2 DM.

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.

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 investigate the significance of test of receptor activator of nuclear factor?kappa B(NF?κB)ligand(RANKL)in serum and urine for the diagnosis of osteoporosis. Methods A total of 53 patients with osteoporosis(the experimental group)and 45 healthy controls(the normal control group)were recruited in this study. The expression levels of RANKL in serum and urine was measured and compared by enzyme?linked immunosorbent assay. Results The serum and urine levels of RANKL in the experimental group were significantly higher than those in the normal control group(P<0.01). The areas under receiver operating characteristic(ROC)curve of serum and urine RANKL were 0.898 and 0.734, respectively. The combined detection of serum and urine RANKL and Ca2+reached a high sensitivity of 89.5%and a specificity of 86.1%for diagno?sis of osteoporosis. Conclusion RANKL may be closely associated with the progression of osteoporosis. Serum and urine RANKL test may be help?ful in the diagnosis of osteoporosis.

Preeclampsia(PE) is a unique disease to pregnancy women,and women who had a history of preeclampsia significantly increased the risk of cardiovascular disease.Preeclampsia etiology and pathogenesis is not clear yet,it may have common pathophysiology with cardiovascular disease(CVD),such as oxidative stress,endothelial injury,insulin resistance,lipid metabolic disorder and so on.The article reviewed the relationship between preeclampsia and long-term cardiovascular disease among women,especially discussed the disease such as coronary heart disease,hypertension and stroke,to find the association and to explore the potential risk management options for these high-risk women.To block,intervene,and prevent cardiovascular disease starting with preeclampsia,it is of significance to the cardiovascular health of over 300 million women worldwide.
