Extracts of Radix Pueraria and Herba Cirsii, obtained by the same isolating procedure,were examined with IR spectra. Results showed that the IR spectra of Radix Pueraria lobota and Herba Cirsii,collected at different times had distiuct characteristics,consistency aud repcatability.The spectra of Radix Pueraria thomsonii also showed characteristic evidence.Accordingly, Radix pueraria and Herba Cirsii may be well distinguished by means of IR spectra.

Objective To discuss the risk factors of free wall rupture (FWR) in acute ST-segment elevation myocardial infarction (STEMI) patients. Methods We retrospectively reviewed all patients (n=1247) with STEMI hospitalized in CCU from January 2005 to July 2010. Results FWR occurred in 29 patients(2.3%). Of these 1247 patients, 128 (10.2%) patients received thrombolytic therapy, 623 (50.0%) patients underwent primary PCI. Compared to No-FWR group, FWR group has signiifcant differences in age (62.4±6.4 y vs. 66.6±8.3 y, P<0.05), hypertenion (29.7%vs. 21.8%, P>0.05), diabetes mellitu (55.2%vs. 23.5%, P=0.022), presence of heart failure on admission (Killip≥Ⅱ) ( 16.4%vs. 34.0%, P<0.05), Peak value of hCRP[20.33 (15.02, 81.25) vs. 43.35 (16.56, 126.78)], no-history of pervious MI (10.3%vs. 18.4%, P=0.018). Multivariate logistic regression showed that age (≥70 years old), Killip≥Ⅱ, hCRP ( > 100 mg/L) and thrombolytic therapy were independent risk factors of FWR. Conclusions STEMI patients with advanced age, Killip≥Ⅱ, hCRP and thrombolytic therapy were more vulnerable of FWR.

Objective To investigate the correlation of serum interleukin-6 (IL-6) and C-reactive protien (CRP) lev?els with left atrial thrombus and severe spontaneous echocontrast (SEC) in patients with atrial fibrillation (AF). Methods A case-control study of patients with atrial fibrillation (n=76) was carried out. All patients were divided into control group (n=45) and study group (n=31) according to their conventional echocardiography performance. Serum IL-6 and CRP were exam?ined in both groups. Results The levels of serum IL-6 in patients with thrombus and severe SEC were (324.13±42.86) ng/L and (332.29±53.17) ng/L, respectivly which is higher than that in patient without thrombus or without severe SEC (108.75± 25.43) ng/L and (93.59 ± 27.82) ng/L respectively. In parallel, CRP levels in patients of thrombus and severe SEC were (66.97 ± 17.65) mg/L and (71.81 ± 20.19) mg/L respectively which is higher than that in patients without thrombus or without severe SEC (17.28±6.52) mg/L and (16.76±8.73) mg/L respectively. All differences were of statistically significant(P<0.05). Conclusion Increase of serum IL-6 and CRP as well as high systemic inflammatory state correlate with left atrial thombus and severe SEC in patients with AF.

Objective To study the diagnostic value of common inflammatory markers in patients with infectious diseases. Methods One hundred sepsis patients, 100 viral infection patients,100 pulmonary tuberculosis patients and 100 gonorrhea patients were analyzed retrospectively. The contents of procalcitonin (PCT), C-reactive protein (CRP), haptoglobin (HP), ceruloplasmin (CER), α1-acid glycoprotein (α1-AAG), α1-antitrypsin (α1-AAT), white blood cell count (WBC) and erythrocyte sedimetation rate (ESR) were measured. The receiver operating characteristic curve (ROC curve), sensitivity, specificity, positive predictive value, negative predictive value, Youden's index,positive and negative likelihood ratios and total coincidence rate were calculated respectively. Results The area under the ROC curve, sensitivity, specificity, Youden's index and positive likelihood ratios,positive predictive value and total coincidence rate of PCT in sepsis patients were 0. 895, 0.84, 0.92,0.76, 10.50, 0.91 and 0.88, respectively, which were superior to CRP, HP, CER, α1-AAG, α1-AAT, WBC and ESR. Conclusions PCT is a better inflammatory reactive parameter than other parameters currently applied in practice and may serve as a rapid and sensitive test in the early stage of severe bacterial infections.

BACKGROUND:Mason II type and III type radial head fractures with massive bone are mainly treated by open reduction and metal fixation, but metal implants have to be removed in the second operation, which increased patients’ travail and financial burden. Absorbable screw/rod also can be used to treat radial head fractures, and has its special advantages due to the low price and no second operation. OBJECTIVE:To compare the clinical therapeutic effects of absorbable rod and Herbert screw for the treatment of Mason II or III type radial head fractures. METHODS:A total of 80 patients with Mason II and III type radial head fractures were equal y assigned to experimental and control groups. They received open reduction and internal fixation. The experimental group was treated with absorbable rod and the control group received Herbert screw. RESULTS AND CONCLUSION:A total of 79 patients were fol owed up for averagely 34 months. No significant difference in average operative time, fracture healing time, Broberg and Morrey elbow scores and incidence of complications was detected between the experimental and control groups (P>0.05). However, treatment costs were lower in the experimental group than in the control group (P<0.05). Results indicated that the therapeutic effects between absorbable rod and Herbert screw for Mason II or III type radial head fractures were similar. However, absorbable rod for radial head fractures can avoid the second operation for removal of the implant. Therefore, we recommend absorbable rod in the choice of internal fixation materials.

BACKGROUND:At present, the methods of treating unstable comminuted radial head fractures contain open reduction and internal fixation and metal prosthesis replacement. There were success cases treated by the two methods, but some shortcomings simultaneously existed.
OBJECTIVE:To compare the clinical therapeutic effects of replacement of the radial head with metal prosthesis with open reduction and internal fixation for the treatment of unstable comminuted radial head fractures.
METHODS:A prospective randomized control ed analysis was performed in 45 cases of unstable comminuted radial head fractures. These cases received open reduction and internal fixation and metal prosthesis replacement. This study compared the Broberg and Morrey elbow joint function score and the incidence of complications after fixation, and performed statistical analysis.
RESULTS AND CONCLUSION:The subjects were fol owed up for 1-5 years, averagely 2.8 years. According to Broberg and Morrey scores, the average score was 90.1 and the incidence of complications was 13.6%in the prosthesis replacement group. The average score was 76.8 and the incidence of complications was 47.9%in the open reduction. Significant differences were visible between the two groups (P<0.01). Compared with the open reduction group, prosthesis replacement for unstable comminuted radial head fractures obtained better joint function and lower incidence of complications.

Peripheral exudative hemorrhagic chorioretinopathy (PEHCR) is a peripheral retinal disease characterized by subretinal hemorrhage and/or subretinal pigment epithelial hemorrhage or exudation. It is often misdiagnosed as age-related macular degeneration, polypoidal chorioretinopathy or choroidal melanoma. With the development of multimodal imaging, PEHCR has different features under different examinations, such as B-scan ultrasound, fluorescein fundus angiography, optical coherence tomography and so on, which contributes to differention from other diseases. Clinical treatments for the disease include intravitreal injection of retinal photocoagulation therapy, anti-vascular endothelial growth factor, pars plana vitrectomyand so on, but there is still no universal consensus. In order to gain a deeper understanding of the clinical features, treatment options and prognosis of PEHCR, minimize missed diagnoses and misdiagnoses, and improve treatment efficiency, further research is required.

Objective To evaluate the value of MSCT, MRI and SPECT in detecting acute myocardial ischemia in Chinese mini-swine model. Methods A total of six male mini-pigs were recruited with a mean body weight of (21.6 ± 1.2) kg. All pigs were scanned on MSCT before the ligation of distal segment of Left anterior descending artery. Then, MSCT was rescanned every 2 h from ligation till 8 h latter.MRI, SPECT and the last MSCT scan were performed within 24 h one by one. Finally pathological examination was carried out right after the pig killed. Results One pig died during operation, the other 5 finished all the examinations. The pathological staining showed the same areas of myocardial infarction in the left ventricular anterior wall with the all the imaging findings, including low perfusion region of MSCT arterial phase at 2-24 h, low perfusion region of SPECT at 24 h and low perfusion region of MRI first pass phase at 24 h. Three of 5 pigs showed enhanced edge of low perfusion region on MSCT delayed scan at 4-8 h. The mean CT values in the region with reduced first-pass perfusion were 75.9,36.4, 35. 2,37. 8,37.4,33.3 HU on MDCT image at baseline, 2-8 h after operation and within 24 h after operation, respectively,and there were statistically significant difference of CT values ( F = 12. 341, P ＜0. 01 ) between preoperative and all postoperative MSCT scan. There were no statistically significant difference (F = 2. 278, P = 0. 792)among all postoperative MSCT scan. At baseline, 2-8 h after operation and within 24 h, the average volumes of stroke volume(SV)were 21.7,11.9,10.3,11.4,12. 3,12.6 ml, respectively, while the average volume of end-systolic volume( ESV)were 15.2,23.4,25.0,24. 4,25.3,22. 8 ml,respectively. The average volume of end-diastolic volume ( EDV ) at these time point were 37. 0,35.4,35.0,35.7,37. 6,37.5 ml,respectively and the average percentage of ejection fraction (EF) were 58.9% ,33.8% ,29. 0%, 31.9%,32.6% ,33.5% ,respectively. SV(F =22. 349, P＜0.01) ,ESV (F=8. 810, P＜0.01) ,EF(F =27. 240,P ＜ 0. 01 ) were all significantly different among all postoperative MSCT scan except EDV ( F = 2. 339, P =0. 079). Infarct size, which was defined as the proportion of the area of infarction to that of the entire heart,were (39.4 ±12.6)% for MSCT,(37.2 ± 10.0)% for MRI, (35.9 ±9.6)% for TTC, respectively.There were no significant differences of infarct size between TTC and MSCT (t =0. 612, P =0. 574), TTC and MRI (t=0.820, P=0.458), MSCTand MR (t=0. 425 ,P =0. 692 ). Conclusions MSCT,MRI and SPECT were all able to be used to detect the myocardial infarction in acute myocardial ischemia model The infarct size defined on MSCT, MRI and pathology were consistent. The density of ischemic myocardium and cardiac function did not change over the time within 24 h right after infarction.

OBJECTIVETo evaluate the application of small intestine double stoma and succus entericus reinfusion in the patients with severe intra-abdominal infection.

METHODSTen patients with high intestinal perforation from February 2005 to November 2014 were enrolled in the study. All the cases received emergency operation. Small bowel with intestinal perforation was resected, and double stoma was applied in the proximal and distal small intestine. When abdominal infection under control, total enteral nutrition was successfully administered from nasogastric tube. The succus entericus from the proximal intestine was collected and transfused back to the distal intestine. Stool was collected and fecal nitrogen, fat and carbohydrate contents were determined. Related serum protein levels were measured.

RESULTSAs compared to pre-reinfusion, the absorption rate of carbohydrate [(90.9±7.8)% vs. (82.7±15.2)%], fat [(87.6±6.4)% vs. (59.1±10.8)%], and nitrogen [(82.4±9.8)% vs. (67.2±15.4)%] increased after succus entericus reinfusion (P<0.05). The serum protein levels increased significantly as well[fibronectin: (285.6±3.6) vs. (157.0±22.6) mg/L, P<0.01; transferrin: (4.86±0.21) vs. (3.60±0.25) g/L, P<0.05; pre-albumin: (291.3±112.5) vs. (199.1±53.3) mg/L, P<0.05].

CONCLUSIONSmall intestine double stoma and succus entericus reinfusion are effective in improving the absorption of carbohydrate, fat and nitrogen in the patients with severe intra-abdominal infection.

Objective To investigate the biomechanical properties and clinical effects of the unilateral/bilateral percutaneous vertebroplasty (PVP) on the treatment of osteoporotic vertebral compression fractures in elderly patients. Methods The finite element models of the unilateral/bilateral percutaneous vertebroplasty (PVP) in osteoporotic vertebral compression fractures were established to evaluate changes in strain and stress of the fractured vertebra after surgery. Eighty patients with osteoporotic vertebral compression fractures underwent unilateral or bilateral PVP were collected for retrospective analysis. The operation time,intraoperative fluoroscopy times,injected bone cement volume, bone cement leakage rate and visual analogue scales (VAS) score between the two groups were analyzed. Results The maximum strain and stress in unilateral PVP group were 1.18 times and 1.15 times of those in bilateral PVP group,respectively.The operation time and intraoperative fluoroscopy times in unilateral PVP group were obviously smaller than those in bilateral PVP group (P<0.001). There was no statistical significance in the injected bone cement volume, bone cement leakage rate, and VAS score between the two groups (P>0.05).Conclusions The biomechanical effect of unilateral PVP was similar to that of bilateral PVP. The puncture needle localization of unilateral PVP for treating elderly patients with osteoporotic vertebral compression fractures had the advantage of less operation time and limited X-ray exposure.
