OBJECTIVETo compare the efficacy difference in the treatment of shoulder pain in post-stroke shoulder-hand syndrome among floating acupuncture, oral administration of western medicine and local fumigation of Chinese herbs.

METHODSNinety cases of post-stroke shoulder-hand syndrome (stage I) were randomized into a floating acupuncture group, a western medicine group and a local Chinese herbs fumigation group, 30 cases in each one. In the floating acupuncture group, two obvious tender points were detected on the shoulder and the site 80-100 mm inferior to each tender point was taken as the inserting point and stimulated with floating needling technique. In the western medicine group, mobic 7.5 mg was prescribed for oral administration. In the local Chinese herbs fumigation group, the formula for activating blood circulation and relaxing tendon was used for local fumigation. All the patients in three groups received rehabilitation training. The floating acupuncture, oral administration of western medicine, local Chinese herbs fumigation and rehabilitation training were given once a day respectively in corresponding group and the cases were observed for 1 month. The visual analogue scale (VAS) and Takagishi shoulder joint function assessment were adopted to evaluate the dynamic change of the patients with shoulder pain before and after treatment in three groups. The modified Barthel index was used to evaluate the dynamic change of daily life activity of the patients in three groups.

RESULTSWith floating acupuncture, shoulder pain was relieved and the daily life activity was improved in the patients with post-stroke shoulder-hand syndrome, which was superior to the oral administration of western medicine and local Chinese herbs fumigation (P < 0.01). With local Chinese herbs fumigation, the improvement of shoulder pain was superior to the oral administration of western medicine. The difference in the improvement of daily life activity was not significant statistically between the local Chinese herbs fumigation and oral administration of western medicine, the efficacy was similar between these two therapies (P > 0.05).

CONCLUSIONThe floating acupuncture relieves shoulder pain of the patients with post-stroke shoulder-hand syndrome promptly and effectively, and the effects on shoulder pain and the improvements of daily life activity are superior to that of the oral administration of western medicine and local Chinese herbs fumigation.

BACKGROUNDPrimary percutaneous coronary intervention (PCI) is the best treatment of choice for acute ST segment elevation myocardial infarction (STEMI). This study aimed to determine the clinical outcomes of tirofiban combined with the low molecular weight heparin (LMWH), dalteparin, in primary PCI patients with acute STEMI.

METHODSFrom February 2006 to July 2006, a total of 120 patients with STEMI treated with primary PCI were randomised to 2 groups: unfractionated heparin (UFH) with tirofiban (group I: 60 patients, (61.2 ± 9.5) years), and dalteparin with tirofiban (group II: 60 patients, (60.5 ± 10.1) years). Major adverse cardiac events (MACE) during hospitalization and at 4 years after PCI were examined. Bleeding complications during hospitalization were also examined.

RESULTSThere were no significant differences in sex, mean age, risk factors, past history, inflammatory marker, or echocardiography between the 2 groups. In terms of the target vessel and vascular complexity, there were no significant differences between the 2 groups. During the first 7 days, emergent revascularization occurred only in 1 patient (1.7%) in group I. Acute myocardial infarction (AMI) occurred in 1 (1.7%) patient in group I and in 1 (1.7%) in group II. Three (5.0%) patients in group I and 1 (1.7%) in group II died. Total in-hospital MACE during the first 7 days was 4 (6.7%) in group I and 2 (3.3%) in group II. Bleeding complications were observed in 10 patients (16.7%) in group I and in 4 patients (6.7%) in group II, however, the difference was not statistically significant. No significant intracranial bleeding was observed in either group. Four years after PCI, death occurred in 5 (8.3%) patients in group I and in 4 (6.7%) in group II. MACE occurred in 12 (20.0%) patients in group I and in 10 (16.7%) patients in group II.

CONCLUSIONSDalteparin was effective and safe in primary PCI of STEMI patients and combined dalteparin with tirofiban was effective and safe without significant bleeding complications compared with UFH. Although there was no statistically significant difference, LMWH decreased the bleeding complications compared with UFH.

OBJECTIVETo investigate the different effects of Shengmai injection on testicular injury after testis torsion/detorsion in rats of different ages.

METHODSSixteen healthy male SD rats aged 3, 6 and 12 weeks were equally randomized into an experimental group (testicular torsion/detorsion plus Shengmai injection) and a control group (testicular torsion/detorsion plus saline). The rat models of testicular torsion were killed 24 h after surgery for the measurement of total antioxidant capacity (T-AOC), superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in the testis.

RESULTSCompared with the controls, the 3- and 6-week-old rats of the experimental group showed no significant changes in T-AOC, SOD activity and MDA content (P > 0.05), while the 12-week-old experimental rats exhibited a remarkable increase in SOD and T-AOC and an obvious decrease in MDA content (P < 0.05).

CONCLUSIONShengmai injection has a protective effect against acute ischemia-reperfusion testicular injury after torsion/detorsion in rats, but the effect varies with the age, more obvious in older ones.

OBJECTIVESTo investigate the mechanical properties of bilateral atlantoaxial trans-articular screws and atlas laminar hooks instrumentation with finite element method.

METHODSThere was a volunteer with age of 28 years old, body height 172 cm, body weight of 60 kg and without cervical deformity by X rays. The ligamentous, nonlinear, three-dimensional finite element models of normal upper cervical spine (C0-3) was developed and validated. The destabilized model with bilateral atlantoaxial trans-articular screws and atlas laminar hooks was evaluated for quasistatic loading.

RESULTSThe finite element model of upper cervical spine consists of 229,047 nodes and 152,475 elements, and correlated well with experimental data for all load cases and could be used for experiment. The finite model with bilateral atlantoaxial trans-articular screws and atlas-laminar hooks predicted that the maximum Von Mises Stress was in the region in which screws penetrated the atlantoaxial articular facet. The novel instrumentation resulted in sufficient stability.

CONCLUSIONThe bilateral atlantoaxial trans-articular screws and atlas laminar hooks instrumentation is useful and effective for atlantoaxial arthrodesis.

BACKGROUNDHemodynamic evaluation is crucial for the management of patients with pulmonary hypertention. Clinicians often prefer a rapid and non-invasive method. This study aimed to examine the feasibility of transthoracic echocardiography for the measurements of hemodynamic parameters in patients with pulmonary hypertension.

METHODSA prospective single-center study was conducted among 42 patients with pulmonary hypertension caused by different diseases. Transthoracic echocardiography and right-heart catheterization were performed within 24 hours. Pulmonary artery systolic, diastolic and mean pressure (PASP, PADP and PAMP), cardiac output (CO), and pulmonary capillary wedge pressure (PCWP) were measured by both methods. A linear correlation and a Bland-Altman analysis were performed to compare the two groups of hemodynamic parameters.

RESULTSA good correlation was found between invasive and non-invasive measurements for PASP (r = 0.96), PADP (r = 0.85), PAMP (r = 0.88), CO (r = 0.82), and PCWP (r = 0.81). Further agreement analysis done by the Bland-Altman method showed that bias and a 95% confidence interval for PASP, PADP, and CO were clinically acceptable while great discrepancies existed for PAMP and PCWP.

CONCLUSIONSThe non-invasive measurements by PASP, PADP, and CO in patients with pulmonary hypertension correlate well with the invasive determinations. Transthoracic echocardiography (TTE) was inappropriate for estimating PCWP and PAMP.

OBJECTIVETo study the clinical value of magnetic resonance spectroscopy (MRS) image in stereotactic biopsy for brain lesion.

METHODSFrom April 2008 to April 2010, 126 cases (72 male and 54 female, aged from 10 to 82 years, mean 45 years) of brain lesion which were difficult to diagnose were divided into two groups by random number table, 62 cases were executed for MRI-guided frameless stereotactic biopsy (MRI group), 64 cases were executed for MRI and MRS-guided frameless stereotactic biopsy (MRS group). Operation used MRI and Three-dimensional MRS image to locate, and used frameless CAS-R-2 robots to carry out the positioning operating.

RESULTSNo surgery-related deaths and infections. Pathological diagnosis was 106 cases of brain tumors, 6 cases of inflammatory disease, 4 cases of tumor-like demyelinating disease and multiple sclerosis, 3 cases of neurodegenerative disease, 7 cases failed to obtain positive pathological diagnosis. The total rate of positive diagnosis was 94.4%, the positive rate in MRS-guided stereotactic biopsy group was 98.4% (63/64), the positive rate of conventional MRI-guided biopsy group was 90.3% (56/62), and there was statistically significant difference between the two groups (χ(2) = 3.92, P = 0.047). Four cases presented with postoperative complications, the complication rate was 3.2% (4/126); the complications were cerebral hemorrhage associated with aphasia, epilepsy, subcutaneous hematoma, gastrointestinal bleeding, which were improved after treatment.

CONCLUSIONSMRS-guided stereotactic biopsy group has a higher positive rate than MRI-guided stereotactic biopsy group, indicating that this method can improve the positive rate of diagnosis, and thus will help to formulate treatment plan for brain lesion.

Purpose: Systemic inflammatory response is a critical factor that promotes the initiation and metastasis of malignancies including pancreatic cancer (PC). This study was designed to determine and compare the prognostic value of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and fibrinogen-to-albumin ratio (FAR) in resectable PC and locally advanced or metastatic PC. Materials and Methods: Three hundred fifty-three patients with resectable PC and 807 patients with locally advan-ced or metastatic PC were recruited in this study. These patients were classified into a training set (n=758) and a validation set (n=402). Kaplan-Meier survival plots and Cox proportional hazards regression models were used to analyze prognosis. Results: Overall survival (OS) was significantly better for patients with resectable PC with low preoperative PLR (p=0.048) and MLR (p=0.027). Low FAR, MLR, NLR (p < 0.001), and PLR (p=0.003) were significantly associated with decreased risk of death for locally advanced or metastatic PC patients. FAR (hazard ratio [HR], 1.522; 95% confidential interval [CI], 1.261 to 1.837; p < 0.001) and MLR (HR, 1.248; 95% CI, 1.017 to 1.532; p=0.034) were independent prognostic factors for locally advanced or metastatic PC. Conclusion The prognostic roles of FAR, MLR, NLR, and PLR in resectable PC and locally advanced or metastatic PC were different. FAR showed the most prognostic power in locally advanced or metastatic PC. Low FAR was positively correlated with OS in locally advanced or metastatic PC, which could be used to predict the prognosis.

Objective To investigate the epidemiological status and the anticoagulation treatment of atrial fibrillation (AF) patients,and to provide evidence for improving anticoagulation therapeutic effect in AF patients.Methods We performed a cross-sectional epidemiological investigation of 1 000 patients and out-patients with AF in Huashan Hospital.The clinical data including clinical feature,coexistent diseases,auxiliary examination,and treatment regimen of these patients were collected.The clinical features and anticoagulation status of AF patients were analyzed based on the stroke history,stroke risk evaluation and CHA2DS2-VASc score stratification.Results The mean age of these AF patients was (72.1 ± 11.1) years old.The most common coexistent diseases were hypertension (65％),coronary heart disease (32％) and diabetes (27％).About 6％ of the AF patients were diagosed with non-valvularatrial fibrillation (NVAF),and 22％ had stroke history.Patients were divided into two groups according to their stroke history.Compared with the non-stroke group,the stroke group was found to be older,with longer course of AF and poorer hypertension control.The overall anticoagulation rate was 32 ％ and antiplatelet rate was 46 ％.The anticoagulation rate of stroke group was 44％,higher than the non-stroke group (P＜0.001) but 78％ of these patients began anticoagulation therapy after the occurrence of stroke.When CHA2 DS2-VASc scores of NVAF patients were 2 to 5,the anticoagulation proportion increased gradually.When the scores were 2 to 6,the antiplatelet ratio increased gradually.But when the scores were 7-8 points,both anticoagulation and antiplatelet rates were in decline.Conclusions The anticoagulation rate in AF patients was still low at present,while relatively higher in patients with stroke.Anticoagulation could prevent stroke,AF patients still could benefit from anticoagulation after stroke,but anticoagulation before stroke could get more benefits.

Aim To screen and study the effects of Tao Hong Si Wu decoction(THSWD)-mediated treat-ment on circular RNA(circRNA)expression profiles in rats with middle cerebral artery occlusion(MCAO),and investigate the possible roles and molecular mecha-nisms of THSWD.Methods Next-generation RNA sequencing was conducted to identify circRNA expres-sion profiles in MCAO rats after treatment with THSWD and compared with the MCAO model group and control group.Bioinformatics analysis was performed to predict the potential target microRNAs and mRNAs.Gene On-tology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analyses for the potential target mRNAs were applied to explore the potential roles of differentially expressed circRNAs.RT-qPCR was performed to verify circRNAs with significant differences in expression.Results We identified 87 significantly differentially expressed circRNAs between the MCAO group versus the control group,and 86 sig-nificantly differentially expressed circRNAs between the MCAO group versus the THSWD group.respective-ly.Among them,17 circRNAs induced by the MCAO model were reversed via treatment with THSWD.To demonstrate the roles of mRNAs targeted by DECs,the GO and KEGG databases were used.Further analysis revealed that five circRNAs may play important roles in the development of MCAO.Conclusions The com-prehensive expression profile of circRNAs in rats with middle cerebral artery occlusion after THSWD treat-ment is determined for the first time,suggesting that the therapeutic effect of THSWD on MCAO may be a-chieved by regulating the expression of circRNAs.

In 2004, it was the first time that Wollensak and Spoerl had applied physical and chemical cross-linking methods to scleral tissue. They found that the biomechanical strength of cross-linked sclera, induced by riboflavin/ultraviolet A, glyceraldehyde and glutaraldehyde, could be improved and proposed that scleral collagen cross-linking is expected to be a new method for the treatment of pathologic myopia. In recent years, a series of explorations have been made on the effectiveness and adverse reactions of physical and chemical cross-linking in the prevention and treatment of pathologic myopia, including the establishment of various animal models and different myopia modeling methods, the improvement of cross-linking methods, the amelioration of the measurement of biomechanical strength of scleral tissue and the attention of biological parameters such as the thickness of retinal nerve fiber layer and the amplitude of electroretinogram in vivo. Genipin-crosslinking of the scleral collagen combined with posterior scleral contraction/reinforcement has been applied to clinical research. This review summarizes physical cross-linking and the genipin-crosslinking of scleral collagen to explore the effectiveness and safety of the methods in the prevention and treatment of the pathologic myopia.
