Objective To investigate the utility of combined detection of procalcitonin(PCT ) ,C‐reactive protein(CRP)and preal‐bumin(PA)in elderly patients with acute respiratory infectious diseases .Methods Detected the serum procalcitonin(PCT) ,C‐reac‐tive protein(CRP) and prealbumin(PA) of 110 elderly patients with acute respiratory infectious diseases and 40 healthy people dur‐ing the same period as control group .The levels of PCT and CRP and PA among groups were compared before and after treatment . The 110 elderly patients with acute respiratory infections were divided into into bacterial infection group(n= 40) ,virus infected group(n=34) and mixed infection group (n=36) according to the pathogen type .Results Before treatment ,the PCT and CRP of bacterial infection group and mixed infection group were significantly higher than that of control group ,while the level of PA was lower ,and the difference were statistically significant(P<0 .01) .When Viral infection group compared with the control group ,all the indicators showed no significant difference(P>0 .05) .After treatment ,there was no significant difference .The sensitivity ,spe‐cificity ,accuracy ,positive predictive value ,negative predictive value ,and Youden′s index of combined detection of the three indica‐tors were higher than those of single detection in acute respiratory infection .Conclusion PCT ,CRP and PA can be used as the di‐agnostic indexes for elderly patients with acute respiratory tract infection .The combined detection of the 3 indexes can improve the accuracy of early diagnosis of acute respiratory tract infections in elderly patients and can be used in therapeutic efficiency evalua‐tion .

OBJECTIVE: To evaluate the preemptive analgesia effects of both the parecoxib sodium and the pentazocine in patients undergoing nasal endoscopic surgery. METHOD: In the randomized, double blind, controlled study, 120 patients undergoing septoplasty were divided into 3 groups (n = 40): group A received parecoxib 40 mg by muscle injection 30 min before the operation; group B received pentazocine 30 mg; group C received an equal volume of saline. The preemptive analgesia effect was evaluated with VAS scores which recorded at different time points. The proportion of participants using rescue analgesia after the operation were recorded as additional measures of preemptive analgesia. RESULT: Intra-operative as well as the postoperative pain scores were less in the group A and group B than in the control group. Fewer participants required rescue medication after operation with parecoxib as well as pentazocine than placebo. However there were no difference in the preemptive effects between the group A and group B. CONCLUSION Administration of both the parecoxib and pentazocine before the nasal endoscopic surgery can provide preemptive analgesia without serious adverse side effects that deserves popularization in the clinic.

The mechanism of thrombus formation in living vessel wall is complex and involves a combination of blood and vessel wall properties and local flow conditions.The significance，theory and experimental tech-niques of thrombus formation in vivo were comprehensively reviewed.Particularly,the important role of signa-ling pathway and hemodynamic in thrombus formation in vivo was pointed out.The difficulty ic in vivo animal models was analyzed.Some recent new phenomena as welt as new approaches and directions worthy of in-vestigation also were summarized.

The management of medical equipment is a difficult part of health works for CPAPF'smobile health institutions,and it restricts the development of health institutions in a certain extent.So in order to do it well,this paper puts forward some countermeasures for the existing new problems in the management of medical equipment of CPAPF's mobile forces,whose aim is to enhance the ability of medical support for CPAPF's mobile forces.

Objective To investigate the expression, relationship, significance of cyclooxygenase_2 (COX-2) and malonic dialdehyde (MDA) after cerebral ischemic-reperfusion injury and provide basis of treatment. Methods The focal cerebral ischemic-reperfusion model was established with thread embolish of middle cerebral artery. Western blotting, barhituric acid method and neurological evaluation were used to examine the expression of COX-2, MDA in cortex and the changes of neurological function;TTC staining was used to observe the changes of cerebral infarction volume. Results COX-2 prorein expression was correclated well with the MDA(r=0.910,P＜0.01). The content of COX-2 and MDA was very low in sham operation group, they were increased significantly at I2h/R6h model group, with the increase of reperfusion time,they remarkably reached its peak at I2h/R24h,they were slightly lower at I2h/R48h, but still maintained at a high level;Compared with model group, in tetramethylpyrazine(TMP) treatment group, the content of MDA and cerebral infarction volume were markedly decreased(P＜0.01). Conclusion The expression of COX-2 and MDA increases in cerebral ischemic-reperfusion injury.It indicates they may play an important role in the mechanisms of cerebral ischemic-reperfusion injury;TMP has neuroprotective effect.

OBJECTIVE: To evaluate the perioperative analgesic effects of parecoxib sodium in patients undergoing nasal endoscopic surgery. METHOD: In the randomized, double blind, controlled study, 120 patients undergoing septoplasty were divided into 3 groups (n = 40): A group received parecoxib at a dose of 40 mg by muscle injection 30 min before the operation followed by saline at the same volume every 24 h for 48 h; B group received parecoxib at a dose of 40 mg by muscle injection 30 min before the operation followed by 40 mg every 24 h for 48 h; C group received an equal volume of 0.9% saline at the same time points. Patients were assessed with respect to pain score (VAS), rescue analgesia requirement and the side effects during the operation as well as at 3, 24, 48 h after the surgery. RESULT: Intra-operative as well as the postoperative pain scores were less in the A group and B group than in the.control group. Compared with group A, group B had significantly lower VAS score at 24 h after the operation, however there were no significant difference on other time points. Fewer participants of both the A and B groups required rescue medication after operation. CONCLUSION Administration of parecoxib can provide ideal analgesic effects without serious adverse side effects at the perioperative period for patients who received nasal endoscopic operation. Intramuscular parecoxib (40 mg 30 min before the operation followed 40 mg qd for 48 h) designed as preoperative analgesia mode resulted in sufficient perioperative analgesia that deserves popularization in the clinical works.

Objective: To study the effect of antidepressant in treatment of patients with PSD (post-stroke depression) Method: 121 patients with PSD in their rehabilitation period were stratified by results of HAMD and then randomly divided into two groups, the study group (n=64) received Paroxetine 20 mg daily, the control group (n=57) received placebo After 4 months, the result was assessed with HAMD, CSS and ADL (activity of daily living) Result: In the period of rehabilitation of stroke, the degree of neurological impairment (CSS score) was positively correlated to depression (r=0 99, P

Objective To analysis the time of acute cerebral stroke occurrence. Methods The occurrence time of 2675 patients with cerebral infarction (1925 cases,CI group) and intracerebral hemorrhage(750 cases,ICH group) were statisticed by 1 time unit per 2 h from 0∶00. Results There was a time-curve with double peaks of stroke occurrence,like as circadian rhythms of blood pressure in 24 h. ⑴ In CI group,the first peak was 6∶00~10∶00, the second peak was 18∶00~22∶00. The value of the first peak was higher than that of the second(P

In this study, we applied in vivo electroporation(EP) for HBV DNA vaccine administration to improve the cell transfection rate of plasmid DNA and to enhance the immune response. In BALB/c mice (8 mice in each group), the luciferase activity (16170?12533RLU) was 4 digits higher than that of the non EP control (8 02?8 00RLU), the difference between them was very significant ( P
