Objective To assess the value of procalcitonin( PCT) in anti-infective therapy by observing PCT concentration change in therapy. Methods Sixty-eight patients with bacterial infection meet the diagnostic criteria were divided into effective group and invalid group,the PCT level on day 1,day 3,day 5 and day 7 were observed respectively. Results PCT concentrations of two groups showed no sig-nificant difference on day 1. The PCT level of effective group gradually declined and PCT level of invalid group gradually rised with significant difference on day 3,day 5 and day 7(P<0. 05). Conclusion PCT level that is positively correlated with inflammation of infectied patients, which can be used as an effective indicator to optimize antibiotic therapy.

Objective To evaluate the therapeutic effects of early intratympanic steroid of different concentrations and types combined with systemic steroid on severe idiopathic sudden sensorineurl hearing loss(ISSNHL).Methods We reviewed 95 patients with unilateral ISSNHL from January 2012 to June 2016 in the Department of Otolaryngology of the People's Hospital of Changshou and according to the steroid treatment methods,Patients were divided into systemic steroid therapy alone group(group A,30 cases),early intratympanic steroid of low concentration combined with systemic steroid group (group B,32 cases) and early intratympanic steroid of high concentration combined with systemic steroid group (group C,33 cases).Results Total effective rates of the group A,group B and group C were 46.67 ％,56.25 ％,78.79％.Group C was significantly higher than that of group A and group B(P＜0.05);the average pure tone threshold improvement was (46.67±9.32) in group C which was better than group A (20.53±8.83) and group B(25.19± 7.46),the differences were stastically significant (P＜0.01).Conclusion Severe ISSNHL should be treated by intratympanic steroid of high concentration combined with systemic steroid as early as possible in order to rescue the hearing,the efficacy of which is much better than other steroid treatments so far.

Objective T o establish a gas chrom atography-m ass spectrom etry (G C-M S ) m ethod for the determ ination of sulfide ion in blood and apply it to the practical cases. Methods T he 1, 3, 5-tribro-m obenzene w as selected as an internal standard, and 0.2 m L blood sam ple w as collected and analyzed using G C-M S after α-B rom o-2, 3, 4, 5, 6-pentafluorobenzyl brom ide derivatization. Results T he m ass concentration of sulfide ion in blood had good linearity in the range of 0.2-40μg/m L w ith a lim it of detection (L O D ) of 0.05μg/m L . T he m ass concentration of sulfide ion w as less than 0.05μg/m L in blank blood from different sources such as healthy subjects and dead cases. In 3 sulfide poisoning cases, sul-fide ion w as detected in the blood sam ples of 6 victim s, and the m ass concentration range w as 1.02-3.13μg/m L . Conclusion T his study establishes a m ethod for investigation of sulfide ion in blood w hich has been applied successfully to the cases of fatal sulfide poisonings.

Objective T o analyse the m etabolic changes in urine of rats w ith brodifacoum intoxication, and to reveal the m olecular m echanism of brodifacoum-induced toxicity on rats. Methods B y establish-ing a brodifacoum poisoning rats m odel, the urine m etabolic profiling data of rats w ere acquired using high performance liquid chromatography-timeofflightmassspectrometry (HPLC-TOF-M S).The orthogo-nal partial least squares analysis-discrim ination analysis (O PLS-D A ) w as applied for the m ultivariate statistics and the discovery of differential m etabolites closely related to toxicity of brodifacoum . Results O PLS-D A score plot show ed that the urinary m etabolic at different tim e points before and after drug adm inistration had good sim ilarity w ithin tim e period and presented clustering phenom enon. C om paring the urine sam ples of rats before drug adm inistration w ith w hich after drug adm inistration, tw enty-tw o m etabolites related to brodifacoum-induced toxicity w ere selected. Conclusion T he toxic effect of brodi-facoum w orked by disturbing the m etabolic pathw ays in rats such as tricarboxylic cycle, glycolysis, sphin-golipid m etabolism and tryptophan m etabolism , and the toxicity of brodifacoum is characterized of accu-m ulation effect. The m etabonom ic m ethod based on urine H PLC-TO F-M S can provide a novel insight into the study on m olecular m echanism of brodifacoum-induced toxicity.

Objective To compare the clinical outcomes of percutaneous cannulated lag screws versus posterior buttress plate in the fixation for posterior malleolar fractures.Methods We reviewed the 167 patients who had been treated between January 2010 and December 2014 for ankle fracture involving larger than 25％ of the articular surface of the posterior malleolus.They received posterior malleolus fixation with percutaneous cannulated lag screws or with a buttress plate.In the cannulated screw group (84 patients),there were 47 males and 37 females,aged from 23 to 72 years (average,49.7 ±9.1 years),and 39 cases of type B and 45 ones of type C according to the Dennis-Webber classification.In the buttress plate group (83 patients),there were 38 males and 45 females,aged from 31 to 69 years (average,52.3 ± 8.3 years),and 45 cases of type B and 38 ones of type C according to the Dennis-Webber classification.At 6 and 12 months postoperation and the final follow-up,the ankle motion was evaluated using American Orthopaedic Foot and Ankle Society (AOFAS) score and range of motion (ROM).Results The average operation time for the cannulated screw group was significantly shorter than for the buttress plate group (Z =-9.145,P ＜ 0.001).No fracture nonunion,reduction loss or incision infection happened in either group.In the cannulated screw group,we detected malunion with a step-off beyond 2 mm in 5 patients,and penetration of one cannulated lag screw into the tibiofibular syndesmosis in 3 patients.In the buttress plate group,we detected toe flexion contracture in 4 patients,and uncomfortable feeling in ankle motion in 7 patients.At the final follow-up,X-rays and CT scans in the 2 groups showed no obvious post-traumatic osteoarthritis of the ankle.There were no significant differences between the 2 groups regarding the AOFAS scores at 6 and 12 months postoperation and the final follow-up(P ＞ 0.05);the AOFAS scores at the final follow-up for all the patients were significantly different from those at 6 and 12 months postoperation (P ＜ 0.05).At the final follow-up,there were no significant differences between the 2 groups regarding ROMs of dorsal flexion,plantar flexion,varus or valgus (P ＞ 0.05).Conclusions As there are no significant differences between the percutaneous cannulated lag screws and posterior buttress plate in AOFAS score and ROM of the ankle after fixation for posterior malleolar fractures,the 2 fixation methods can both achieve good clinical outcomes.Fixation with cannulated lag screws has advantages of indirect reduction and minimal invasion but also a disadvantage of uncertain quality of reduction;fixation with buttress plates has an advantage of anatomical reduction under direct vision but also shortcomings of relatively large invasion and high cost.

AIM: To evaluate the clinical curative effect of Qiangli Tianma Duzhong Capsule in the treatment of acute cerebral infarctions. METHODS: 72 patients were randomly divided into two groups:the treatment group and contrast group.The treatment group on the basis of the regular treatment was assigned to 28 days of treatment with Qiangli Tianma Duzhong Capsule.The contrast group on the same regular treatment was assigned to 28 days of treatment with Fufang Danshen Injection.The European Stroke Score(ESS) and clinical curative effect were evaluated in the treatment group and control group on the 28~(th) day. RESULTS: After 28 days,the European Stroke Score(ESS) of the treatment group(6.02?4.81) decreased significantly in the control group(7.88?4.85)(P
