Objective To evaluate the clinical application effect of fracture liaison service(FLS)mode after percutaneous vertebroplasty(PVP)/percutaneous kyphoplasty(PKP)for thoracolumbar fragility fracture.Methods A prospective study was conducted,and 762 patients with thoracolumbar fragility fracture who underwent PVP/PKP in the department of orthopedics in our hospital from January 2018 to May 2021 were included and divided into the control group(374 cases)and the observation group(388 cases)according to the random number table method.Patients in the control group received routine osteoporosis intervention,while the patients in the observation group implemented FLS through Blue Bull Medical Care or Chronic Health APP on the basis of the control group to systematically manage the osteoporosis treatment after discharge.The follow-up lasted for 12 months,and the 8-item Morisky medication adherence scale(MMAS-8)score,pain visual analogue scale(VAS)score,Oswestry disability index(ODI)score and Hamilton depression rating scale(HAMD)score at discharge,and 6 months and 12 months after discharge of the two groups were compared.The incidences of re-fracture and constipation 6 months and 12 months after discharge of the two groups were compared.The Cobb angle and bone mineral density T-value of injured vertebrae 6 months and 12 months after discharge of the two groups were compared.Results There was no statistically significant difference in the MMAS-8 score,VAS score,ODI score or HAMD score at discharge of patients between the two groups(P>0.05).The VAS score,ODI score and HAMD score 6 months and 12 months after discharge in the observation group were lower than those in the control group(P<0.05),the MMAS-8 score in the observation group was higher than that in the control group(P<0.05),and the incidences of re-fracture and constipation in the observation group were lower than those in the control group(P<0.05).There was no statistically significant difference in the Cobb angle of injured vertebrae 12 months after discharge of patients between the two groups(P>0.05).The bone mineral density T-value 12 months after discharge in the observation group was higher than that in the control group(P<0.05).Conclusion The FLS mode can significantly improve the medication compliance of patients,relieve pain,depression and constipation,improve bone mineral density,and significantly reduce the incidence of vertebral re-fracture in patients after vertebral augmentation surgery;however,it has no significant effect on the Cobb angle of injured vertebrae.

Objectives: To analyze the variations of demography, risk factors and triggering factors in acute myocardial infarction (AMI) patients in Beijing area over recent 40 years from 1970s to 2010s. Methods: Our research included in 2 groups: 1970s group, 1314 patients from Beijing collaborative group of coronary artery disease prevention and treatment from 1972-01 to 1973-12; 2010s group, 2200 patients from China AMI registry in Beijing area from 2013-01-01 to 2014-09-30. Demographic characteristics including gender, age, farmer proportion, risk factors and triggering factors for AMI occurrence were compared between 2 groups. Results: Compared with 1970s group, 2010s group had more patients>70 years of age (15.8% vs 25.6%, P<0.001), more with male gender (68.3% vs 75.6%, P<0.001) and the higher farmer proportion (6.5% vs 14.5%, P<0.001); 2010s group showed more patients with previous histories of stroke (6.2% vs 10.5%), MI (9.5% vs 11.9%) and diabetes mellitus (DM) (6.2% vs 27.6%), all P<0.05; 2010s group presented that less patients were triggered by mental stress (51.1% vs 15.2%, P<0.001), while more were induced by physical stress (40.0% vs 61.1%, P=0.007). Conclusions: There were significant changes in recent 40 years for AMI patients in terms of age, gender, farmer proportion, previous histories of stroke, MI and DM; it appeared as aging, androphany and ruralized trends. Physical stress and unhealthy lifestyle were the major triggering factors for AMI occurrence nowadays, more specific efforts should be conducted for heart disease prevention and education.

Using four Uncariae Cum Uncis materials including Uncaria sinensis (HGT), U. hirsutea (MGT), Jianhe U. rhynchophylla (JHGT) and U. rhynchophylla(GT) as the research objects, the correlations between medicinal materials' yield and photosynthetic ecophysiology-factors in the plant exuberant growth period were studied. Results showed that the Uncaria plants net photosynthetic rate (Pn) changed by unimodal curve. There was not "midday depression" phenomenon. There was a different relationship among the photosynthetic ecophysiology-factors and between photosynthetic ecophysiology-factors and medicinal materials' yield. Pn,Tl,Gs had a significant correlation with medicinal materials' yield（M）and were the most important factors of growth.

OBJECTIVETo investigate clinical characteristics and predictive factors of refractory Mycoplasma pneumoniae pneumonia (RMPP) in children so as to recognize and treat the disease earlier.

METHODThe data including febrile time, inflammatory markers (WBC, neutrophil, CRP) and radiological features of 213 children hospitalized with Mycoplasma pneumoniae pneumonia (MPP) (72 with refractory MPP and 141 with mild MPP were retrospectively analyzed). The primary diagnostic criteria of refractory MPP: the patient's condition still deteriorates after treatment with macrolides for more than 5 days. The independent variables which had significant difference in univariate analysis was analyzed by multivariate logistic regression analysis. The predictive criteria of RMPP were further applied in 100 other patients prospectively. Kappa test was used to evaluate the accuracy rate.

RESULTRefractory MPP patients: febrile time was more than 10 days, white blood cell (WBC) count was (3.8 - 18.5)×10(9)/L in peripheral blood routine test, CRP was 38 mg/L - > 160 mg/L, large lobar consolidation with high density (> 2/3 pulmonary lobe, CT value 40 - 50 HU, without air bronchogram). Mild MPP patients: febrile time was less than 10 days, CRP was often less than 40 mg/L. Independent risk factors for RMPP were febrile time, CRP, large consolidation area with high density in lungs with or without pleural effusion (OR = 1.586, P = 0.017; OR = 4.344, P = 0.001; OR = 2.660, P = 0.012), CT value 40 - 50 HU which were demonstrated by logistic regression analysis. The specificity, sensitivity and Youden index for this diagnostic test were respectively 0.96, 0.94 and 0.90 at a CRP cut off of 40 mg/L. The sensitivity, specificity, and Kappa value for the above criteria to diagnose RMPP were respectively 0.96, 0.94 and 0.9.

CONCLUSIONThe predictive factors for RMPP are febrile time (> 10 days), CRP (> 40 mg/L), large lobar consolidation with high density (> 2/3 pulmonary lobe, CT value > 40 HU with or without pleural effusion) for the purpose of treating earlier.

Objective To investigate the impact of cytochrome P450 (CYP) 2C19 681G>A polymorphism on long-term prognosis of clopidogrel-treated Chinese patients after percutaneous coronary intervention (PCI).Methods Between January 1, 2009 and August 31,2009, 267 patients with coronary heart disease who received PCI and treated with clopidogrel for 12 months were enrolled. CYP2C19*2 was detected by MALDI-TOF MS and patients were grouped into CYP2C19*1/*1(n=130) and CYP2C19*2 carriers group (n=137). Follow-up was 12 months. The primary endpoint was angina recurrence, urgent coronary revascularization, acute myocardial infarction, stent thrombosis, death and the combined end points. Results Baseline data were similar between two groups (P>0.05).Urgent coronary revascularization and the combined end points occurred more frequently in CYP2C19*2 carriers than in CYP2C19*1/*1 patients (7.3% vs. 1.5% and 8.0% vs. 2.3% respectively,all P<0.05). But incidence of angina recurrence, acute myocardial infarction, stent thrombosis and death was similar between two groups (all P>0.05).Hazard risk of 1 year cumulative survival of CYP2C19*2 carriers group was significantly higher than CYP2C19*1/*1 group after PCI (HR=3.59, 95%CI: 1.02-12.87, P<0.05). Conclusion CYP2C19 681G>A polymorphism is a determinant of prognosis in coronary heart disease patients receiving chronic clopidogrel treatment after PCI.

OBJECTIVETo report the treatment of perineal hypospadias with one-stage urethroplasty with circumferential vascular pedicle preputial island flap.

METHODSA circumferential incision was made proximal to the corona and the urethral plate to correct chordee. A U-shaped skin incision was then made surrounding the meatus, and extended to the dorsal prepuce and parallel to the first incision. The tissue between the prepuce and dartos was dissected on the dorsum of penis to fix the prepuce as a neo urethra. After mobilizing the loop shaped skin flap through the button-hole of the pedicle, the internal and external sides of the loop were sutured to construct a new urethra. The catheter was removed 10-14 days (mean, 12.8 days) after operation.

RESULTSSince 1997, 22 patients with perineal hypospadias were treated. Primary healing was achieved in 18 cases (81.8%). Fistula happened in 4 patients. Among them, one case with meatal stenosis was treated with dilatation. Another 3 patients were reoperated. The neo urethral flap was 3.50-18.00 cm (mean, 9.43 cm) in length. All patients were followed up for more than 6 months. Good cosmetic appearance was achieved in 72.7% (16/22) of the patients.

CONCLUSIONSThe circumferential vascular pedicle preputial island flap has advantages of good blood supply and autograft for new meatus, which allows the chordee correction and urethroplasty at one stage. It is a good method for the treatment of perineal hypospadias with severe chordee and penoscrotal transposition.

Objective To compare the clinical characteristics and clinical outcomes in young (≤45 years) female and male coronary artery disease (CAD) patients undergoing percutaneous coronary intervention (PCI). Methods Angiographic and clinical data from 124 premenopausal female patients who underwent elective PCI from April 2004 to February 2008 were compared to age-matched 430 male patients who underwent elective PCI between 2006 and 2007 in our department. All patients were treated according to guidelines and coronary angiography was repeated after 6 months. One year clinical follow-up were performed in all patients. Results Incidences of dyslipidemia, the history of myocardial infarction and smoking were significantly lower in female patients than in male patients (all P < 0.01 ). Left main, left anterior descending and bifurcation lesions were more common while type C lesion and right coronary lesion were less common in young female CAD group compared to young male CAD group (P <0. 01 -0. 05). The average lesion length in female patients was significantly longer than that in male patients [ (20. 36±13.37)mm vs.( 23.04±13.86) mm, P < 0. 05 ]. The in-hospital and follow-up incidences of major adverse cardiac events,stent thrombosis and in-stent restenosis were similar between young female and male CAD patients.Conclusions CAD risk factors were less and vessel lesions were more likely to be found at left main, left anterior descending and bifurcation in young female CAD patients compared to young male CAD patients.The clinical outcomes were similar between young female and male CAD patients.

Objective To explore the correlation between plasma BNP level and left ventricular dysfunction parameters in patients with acute myocardial infarction (AMI). Methods Plasma BNP level was determined in 230 consecutive inpatients with AMI and 111 normal controls. Patients were grouped according Killip grades, LVEF and LVEDd, respectively. BNP was transformed into lnBNP for the normal distribution. The receiver operator characteristic curve (ROC curve) was drawn to determine the best threshold and criteria for diagnosing heart failure. Results After AMI, lnBNP levels increased significantly in proportion with increasing Killip grades (Ⅰ-Ⅲ), and decreasing LVEF(all P<0.05). lnBNP level was significantly higher in LVEDd 55 mm group than in the LVEDd < 55 mm group (P<0.01). lnBNP, LVEDd and LVEF all linearly correlated with Killip grades (P<0.05) and the best correlation was shown between lnBNP and Killip grades(r=0.53, P<0.05). lnBNP also positively correlated with LVEDd(r=0.17 ,P<0.05) and negatively correlated with LVEF(r=-0.41, P<0.01). Among the parameters, InBNP level presented the largest AUC in their ROC curves(P<0.01)for diagnosing decompensated heart failure and cardiogenic shock. The sensitivity, specifiticity and accuracy rates for diagnosing decompensated heart failure were 84.9%, 45.0% and 70.0% respectively by lnBNP at the cut point of 140 ng/L The sensitivity, negative predicting value and accuracy rate for diagnosing cardiac shock were 82.8% ,66.7% and 67.4% respectively by BNP at the cut point of 400 ng/L. Conclusion lnBNP level in hospitalized patients with AMI was positively correlated with Killip grades and LVEDd,negatively correlated with LVEF and could serve as a parameter for diagnosing the decompensated heart failure and excluding the cardiac shock.
