Objective To evaluate the efficacy of ambroxol on community acquired pneumonia (CAP) in elderly patients.Methods Totally 120 patients with CAP were selected and divided into 3 groups:low-dose group (patients received ambroxol 15 mg intravenously,3 times per day,n=40),conventional-dose group (patients received ambroxol 30 mg intravenously,3 times per day,n=40)and control group (patients received routine treatment including antibiotic therapy and oxygen inhalation,n=40).All patients were treated for 7 days.The levels of white blood cell (WBC),high sensitivity C-reactive protein (hs-CRP) and procalcitonin (PCT) were determined dynamically during the treatment.Results The markedly efficient rate,efficient rate and inefficient rate were 62.5％ (25/40),15.0％ (6/40) and 22.5％ (9/40) in low-dose group,82.5％ (33/40),15.0％ (6/40) and 2.5％ (1/40) in conventional-dose group,40％ (16/40),15.0％ (6/40) and 45.0％ (18/40) in control group,respectively.The total efficient rates were 77.5％,97.5％ and 55.0％ in low dose,conventional dose and control groups,respectively.The markedly efficient rate was higher in lowdose,conventional-dose groups than in control group (x2 =15.29,P＜0.05).There was a significant difference in markedly efficient rate between low dose and conventional-dose groups (x2 =4.01,P＜ 0.05).The total efficient rate was higher in low-dose,conventional-dose groups than in control group (x2 20.22,P＜0.05).There was a significant difference in total efficient rate between low dose and conventional-dose groups (x2=7.31,P＜0.05).Compared with before treatment,the levels of WBC,hs CRP and PCT were decreased in 3 groups after treatment (all P＜0.05).The levels of WBC,hsCRP and PCT were decreased more remarkably in low dose,conventional-dose groups than in control group (all P＜0.05).There was a significant difference in the decrease of WBC,hs-CRP and PCT levels between low-dose and conventional-dose groups (all P＜0.05).Conclusions Conventional dose ambroxol treatment (30 mg,iv,3 times/d) is an efficient therapy for community acquired pneumonia in elderly patients.

Objective To observe the effects ofShenkang bolt on the IL-10 and IL-6 of patients with continous ambulatory peritoneal dialysis (CAPD).MethodsA total of 60 patients with CAPD were divided into the control group (n=30) andShenkang bolt observation group (n=30). The control group was treated with convertional treatment of CAPD, low salt, low fat, low phosphorus and high quality diet. The observation group was treated withShenkang bolt based on control group treatment. The clinic effect was detected after treatment for 8 weeks. The serum creatinine was determinated by basic picric acid method, and blood urea nitrogen was determinated by urease test. The clinic and biochemical indicator of Scr, BUN, 24h urine volume, Kt/Vurea, RRF, and ultrafiltration volume were compared between the two groups. The IL-10 and IL-6 were detected by ELISA analysis.Results After treatment, IL-10 (19.56 ± 4.38μg/mlvs. 8.98 ± 2.05μg/ml,t=4.392,P<0.01) was significantly higher in observation group than that in control group, and IL-6 (21.82 ± 3.57μg/mlvs. 49.66 ± 5.26μg/ml,t=5.264,P<0.01) was significantly lower in observation group than that in control group. The RRF (7.86 ± 2.12vs. 5.31 ± 1.62;t=2.436, P=0.046) and ultrafiltration volume (421.37 ± 81.61 ml/dvs. 321.23 ± 71.94 ml/d;t=2.617, P=0.038) was significantly higher in observation group than those in control group. ConclusionShenkang bolt could help patients with CAPD balancethe immune, suppress inflammation and improve the RRF and ultrafiltration volume.

BACKGROUND:In the elderly patients with a variety of diseases, poor physical and compensatory ability results in a high demand for anesthesia during hip replacement and internal fixation. Lumbar epidural anesthesia with ropivacaine is the commonly used method of narcotic analgesics, but this method of anesthesia has been less studied in elderly hip replacement and internal fixation. OBJECTIVE: To investigate the effects of lumbar epidural anesthesia with ropivacaine in elderly hip replacement and internal fixation. METHODS: Data of fifty elderly patients with hip replacement implants and internal fixation, who were treated in the Department of Orthopedics, Affiliated Hospital of Xizang Minzu University from February 2014 to August 2015, were analyzed. 50 patients were randomly divided into continuous epidural anesthesia group and ropivacaine lumbar epidural anesthesia group, with 25 patients in each group. Anesthetic effect was compared. Self questionnaire on risk factors was used for non-conditional Logistic multivariate analysis between the two groups. RESULTS AND CONCLUSION: (1) Anesthetics onset time, the amount of local anesthesia, the use of trimetaphan camsilate agent number, complete block time, heart rate after anesthesia and complication rate were significantly less in the ropivacaine lumbar epidural anesthesia group than in the continuous epidural anesthesia group (P < 0.05). (2) The highest block level, Bromage score, mean arterial pressure after anesthesia and anesthesia satisfaction rate were significantly higher in the ropivacaine lumbar epidural anesthesia group than in the continuous epidural anesthesia group (P < 0.05). (3) Logistic multivariate analysis on postoperative cognitive dysfunction showed that postoperative cognitive dysfunction was strongly associated with age, education, complications, and hip arthroplasty (P < 0.05). (4) Results verified that lumbar epidural anesthesia with ropivacaine showed ideal effects in hip arthroplasty and internal fixation. Postoperative recovery was rapid, and it is safe and reliable.

Long noncoding RNAs( lncRNAs) are classified as transcripts >200 nucleotides in length with lit-tle or no evidence of protein-coding potential, and can regulate gene expression at various levels, including transcriptional regulation, posttranscriptional processing and so on.It has been widely involved in cell differentiation, individual develop-ment and other important life processes.Recent studies show lncRNA-related dysfunction plays critical roles in various dis-eases, indicating that lncRNA may serve as a new target for disease diagnosis and treatment.This review summarizes the functions of lncRNAs, including various modes of lncRNAs in regulating gene expression, the roles of lncRNAs in differen-tiation and development, and the connection between lncRNAs and malignant tumor.

[Objective]To investigate the clinical value of computed radiography(CR),computed tomography(CT)and magnetic resonance imaging(MRI)in spinal tuberculosis.[Method]Forty-one patients with histologically confirmed spinal tuberculosis underwant imaging examinations.Forty-one patients were performed CR,22 CT and 31 MRI.[Result]CR of 38 patients clearly revealed bone changes and narrowed or disappeared disk space.CR of 30 patients well showed the abnormal soft tissue.CT scan of 22 patients clearly depicted calcification and no abnormal was found in pedicles in all the 22 CT scans.CT scan of 21 patients revealed bone changes of vertebral bodies and CT scan of 20 patients showed abnormal soft tissue.The soft tissue was involved in all 31 patients with spinal tuberculosis.Diskspaces were involved in 29 cases and the pedicles were normal in all 31 case.The lesions showed hypointense in T1 scan primarily,hyperintense in T2 scan primarily.[Conclusion]CR is the first imaging approach for spinal tuberculosis.CT well reveal the extent and minute calcification.The extent,abnormal soft-tissue and abnormal disk space are more dramatically demonstrated on MRI imaging.CR,in addition to CT and MRI,is helpful in diagnosis of spinaltubereuinsis.

[Objective]To investigate the value of 16-slice spiral CT(MSCT)postprocessing in styloid process in vivo and provide the vivisection data for diagnosing and curing styloid process syndrome.[Method]Totally 100 volunteers with normal styloid processes underwent 16-slice spiral CT(MSCT). Based on the initial datum,4 kinds of postprocessing including multiple planar reconstruction(MPR), curve planar reconstruction(CPR),surface shaded display(SSD) and volume rendering (VR) were performed.The length and inclination angle of stytoid processes were measured. The distance of between styloid processes and carotid canal external aperture,jugular foramen, stylomastoid foramen ,mastoid process, internal carotid artery and internal jugular vein were surveyed. [Result]The average length of styloid processes was 24.51 mm?3.05 mm, left was 24.33 mm?3.15 mm and right was 24.69 mm?2.95 mm. The anterior inclination angle was 19.35??2.92? and medial was 24.00??4.07?.The distance of between styloid processes and carotid canal external aperture, jugular foramen,stylomastoid foramen ,mastoid process , internal carotid artery and internal jugular vein were 8.53 mm?2.45 mm, 2.87 mm?0.88 mm, 2.34 mm?0.74 mm, 17.23 mm?1.85 mm,6.49 mm?1.58 mm and 3.70 mm?1.46 mm respectively. [Conclusion]Sixteen-slice Spiral CT postprocessing demonstrate the stytoid processes in vivo accurately and fully, among which multiple planar reconstruction and surface shaded display are more valuable, because they can evaluate the length and inclination of the styloid processes and the distance between the processes and their surrounding structures in vivo more accurately.
