OBJECTIVE:To provide reference for rational use of antibiotics in the clinic. METHODS:The study quarterly count the dosage of carbapenems,the department distribution of cultured K. pneumonia (271 strains) during Oct. 1st 2013-Sept. 30th 2014,and it’s resistant rates to carbapenems and then investigate the correlation of dosage of carbapenem and drug-resistance of K. pneumoniae. RESULTS:Carbapenem drugs are mainly used in these departments,such as neurosurgery department,ICU and the departments of transplantation and respiratory. Carbapenem-resistant K. pneumonia was also detected in these departments. More-over,with the usage of carbapenem increased by from 64.24% to 360.63%,and the resistant rates of K. pneumonia increased by nearly 10%. CONCLUSIONS:The resistance rates of K. pneumonia is positively related to the amount of carbapenem;the amount control of carbapenems can delay the generation of K. pneumonia.

Objective To investigate whether or not extracorporeal shock wave (ESW) treatment is safe for treating low back pain caused by lumbar facet joint degeneration by observing its effects on the lumbar segment of the spinal cord.Methods Five adult dogs were used for this study.ESWs were focused on their right L_(4～5) facet joints. The energy output was set at 40% of the maximum output,and a total of 1000 shocks were delivered at a frequency of 120/min.Before and 3 days after the treatment,the somatosensory evoked potentials (SEPs) induced by stimulating the tibial nerve were recorded from the animals' scalps,and the motor function of their hind limbs was evaluated with Tarlov's scale.The animals were then sacrificed and the L_(4～5) segments of their spinal cords were taken for histopatho- logical observation,with the T_(12) segments taken as controls.Results Three days after ESW treatment,the left and the right hind limbs scored 5 and 4 on the Tarlov scale.The amplitude of SEPs decreased and their latency increased. Histopathological observation showed mild swelling of the L_(4～5) segment of the spinal cord with congested veins on the surface.Erythrocyte and leukocyte exudation as well as myelin sheath swelling in the spinal cord were also observed un- der the microscope,but with no demyelination.Conclusion ESW had some adverse effects on the spinal cord when focused on the facet joint.Further studies of the safety range of ESW energy and distance are needed.

Objective To explore the effects of oral rehydration salts [Ⅰ] (ORS Ⅰ) for autonomic nerve mediated syncope(NMS) in children with different hemodynamic patterns.Methods A total of 105 patients with unexplained syncope and prodromal symptoms of syncope who were confirmed as NMS by head-up tilt table test(HUTY) and treated in the Department of Pediatric Cardiovasology,Children's Medical Center,the Second Xiangya Hospital,Central South University,from March 2012 to February 2015.Their ages were from 4 to 18 years old,the average age was (11.96 ± 2.86) years old.Totally 73 cases were diagnosed as vasovagal syncope (VVS) (46 cases were vasodepressor type,27 cases were VVS mixed type or cardioinhibitory type),while 32 cases were diagnosed as postural orthostatic tachycardia syndrome(POTS).Simple random method was used to divide them into conventional therapy (health education and tilt training) plus ORS Ⅰ group (55 cases),and conventional therapy group (50 cases).Patients were followed up for 6-25 (14.82 ± 6.13) months.The recurrence of syncope and review of HUTT outcome assessment in 6 months,treatment was studied to evaluate short-term efficacy of 2 different therapies for NMS in children with different hemodynamic patterns.Taking recurrence of syncope as outcome events,Kaplan-Meier curves were drawn to compare long-term efficacy of different therapies in treating NMS children.Results There was no statistical difference in the short-term efficacy among the different hemodynamic patterns when treated with conventional therapy plus ORS I,or conventional therapy(all P ＞ 0.05).The cumulative efficiency of the conventional therapy plus ORS Ⅰ was superior to that of the conventional therapy for NMS children through the long-term follow-up study (74.5％ vs.52.0％,x2 =14.424,P ＜ 0.01).Patients with vasodepressor patterns had a better response than those with mixed or cardioinhibitory patterns to conventional therapy plus ORS I (90.0％ vs.61.1％,x2 =4.435,P ＜ 0.05).Conclusions Compared with VVS mixed type or cardioinhibitory type,children with VVS vasodepressor patterns are more appropriate to take ORS I as initial treatment.

Purpose:To study the influence of treatment with high dose progesterone on telomerase activity in patients with endometrial adenocarcinoma.Methods:20 patients were treated for adenocarcinoma of endometrium with high dose progesterone and the change of telomerase activity in tumor tissue was examined by PCR-TRAP ELISA before and after treatment.Results:The average A value of tumor telomerase before and after treatment were 0.3636(0～1.11) and 0.1134 (0～0.556),respectively.It shows that telomerase activity in tumor was decreased by treatment with progesterone (P
