Endoscopic ultrasound was initially introduced in 1980s as a diagnostic modality combining echoendoscopes with radial scanning, which permitted reconstruction of cross-sectional images similar to computed tomography. Many studies showed that endogastric ultrasonography is more accurate than endoscopy or CT in evaluating the depth of invasion ( T category) and the involvement of lymph nodes (N category) in patients with gastric carcinoma. In addition to being very useful in tissue acquisition for diagnostic purposes, the principles behind endoscopic ultrasound-guided fine needle aspiration ( FNA) paved the way for the development of therapeutic endoscopic ultrasound, which improve the prognosis of patients with gastric cancer.

Objective To investigate the effects of acupuncture combined with conventional treatment on swallowing function and hemorheology in patients with pseudobulbar palsy following stroke. Methods One hundred thirty-one patients with laughing sickness after cerebral stroke from March 2010 to November 2013 were selected and divided into two group by random number table method:a treatment group (66 patients) and a control group (65 patients). The control group was treated with aspirin and rosuvastatin, while the treatment group was additional treated with acupuncture for benefiting vital energy and eliminating phlegm for 4 weeks. The swallowing function was evaluated by Kubota Water Swallow Test and the hemorheological measurements were performed. Results The total improvement rate of swallowing function in the treatment group was significantly higher than that in the control group (86.36% vs. 64.61%; χ2=8.391, P=0.004). After the treatment, the whole blood viscosities at high shear rate (4.96 ± 0.53 mPa?s vs. 5.32 ± 0.63 mPa?s;t=3.541, P=0.001) and low shear rate (23.23 ± 0.94 mPa?s vs. 23.81 ± 1.01 mPa?s;t=3.403, P=0.001), and the plasma viscosity (1.52 ± 0.24 mPa?s vs. 1.61 ± 0.28 mPa?s;t=1.976, P=0.050) in the treatment group were significantly lower than those in the control group. Conclusion Acupuncture combined with conventional treatment can improve the swallowing function and the hemorheological parameters in patients with pseudobulbar palsy following stroke.

Objective To understand the prevalence of physical activity deficiency and its association with depressive, anxiety symptoms and dissatisfaction of school life among adolescents in Shaoxing, Zhejiang province. Method A total of 3 397 valid questionnaires from adolescents from 80 classes of 2 middle schools (including 1 420 urban and 1 977 town adolescents) were investigated for the study, their average age was (13.73±1.01) years. The Depression Self-rating Scale for Children (DSRSC) and Screen for Child Anxiety Related Emotional Disorders (SCARED) were used to assess the mental health status, while the dissatisfaction of school life was evaluated by the School Life Satisfaction Rating Questionnaire for Adolescent (SLRQA), and the data were analyzed by descriptive statistics and multivariate logistic regression models. Result The self-reported proportion of 3 397 adolescents with physical activity deficiency reached 78.5%, and the prevalence rate of depressive, anxiety symptoms and school life dissatisfaction were 55.2%, 18.9% and 31.1%, respectively. Adjusting on other potential confounders, the result of multivariate logistic regression showed that girls engaged in less physical activities, the OR value (95%CI) was 1.597 (1.348-1.892), while the adolescents with town census register and adolescents having six or more close friends participated in more physical activities, their OR values were 0.785 (0.661-0.931) and 0.565 (0.355-0.900), and insufficient physical activity was positively associated with depressive, anxiety and dissatisfaction of their school lives, their OR values were respectively 1.783 (1.506-2.105), 2.141 (1.664-2.755) and 1.337 (1.101-1.621). Conclusion High prevalence of physical activity deficiency appeared among adolescents in Shaoxing and was closely related to the presence of depressive, anxiety symptoms and school life dissatisfaction.

Objective: To explore the effects of hydrogen sulfide (H 2S) on hypoxic pulmonary vascular smooth muscle cell (VSMC) apoptosis in rats. Methods: Twenty four Wistar rats were divided into 3 groups: control group ( n =8), hypoxia group ( n =8), and hypoxia +NaHS group ( n =8). The plasma level of H 2S was determined by methylene blue spectrophotometric method. VSMC apoptosis was measured by terminal deoxynucleotidyl transferase biotin nick end labeling (TUNEL). The protein expressions of Bcl 2, Fas and caspase 3 in pulmonary arteries were detected by immunohistochemical technique. Results: Compared with rats in the control group, the plasma level of H 2S decreased by 36% in rats of hypoxic group . The apoptotic rate per area in VSMCs detected with TUNEL was significantly decreased by 52.9% in rats of hypoxic group . The expressing integral score of Bcl 2 of VSMCs was increased by 123.9%,while Fas protein expression of VSMCs was decreased by 45% and caspase 3 protein expression of VSMCs was not significantly changed in rats of hypoxia group. But compared with rats in the hypoxia group, the plasma level of H 2S increased by 65% in rats of hypoxia+NaHS group. The apoptotic rate in VSMCs of TUNEL was significantly increased by 62.5% in rats of hypoxia+NaHS group. The Bcl 2 protein expression of VSMCs was decreased by 36.4% in rats of hypoxia+NaHS group. The expressing integral scores of Fas and caspase 3 were significantly higher in rats of hypoxia+NaHS group than in those of hypoxia group. Conclusion: Hypoxia decreased the pulmonary artery smooth muscle cell apoptosis. H 2S inhibited Bcl 2 protein expression of VSMCs and activated Fas and caspase-3 protein expressions of VSMCs, and therefore promoted the pulmonary artery smooth muscle cell apoptosis.

Objective To discuss the characteristics and clinical results of rotating platform high flexion(RDHF)total knee replacement TKR. Methods A total of 61 patients(78 knees)including 13males(15 knees)and 48 females(63 knees)at age range of45-79 years(mean 64.3 years)were treated with Sigma(RP-HF)rotating platform high flexion total knee replacement.Osteoarthritis was found in 56patients and rheumatoid arthritis in 5.By medial parapatella approach,denervation and facet repair of the patella were done,without replacing them. Results All 78 knees were followed up for 3-16 months (mean 10.5 months).the X-ray film demonstrated no prosthesis loosening,patella dislocation or subluxation.According to the knee society scoring system,the preoperative score was 48 points(33-72 points)and the knee functional score was 41 points(28-63 points)on average.After surgery,the knee score was 97points(88-100 points),the functional score 96 points(84-99 points),and the range of motion(ROM)130.(110.-150.)on average.No spin-out or infection were detected. Conclusions The Sigma RP-HF knee system provides sufficient contact area.full range of patella locus and sufficient axial rotation,which helps reach a stable and durable high flexion performance.Our short-term clinical follow up result is good but the advantages of low wear and longevity of the Sigma RP-HF prosthesis still need further study.

BACKGROUND: Currently, the morphologic characteristics of the torn discoid lateral meniscus remain unclear, andmorphological indexes used to evaluate the discoid lateral meniscus tears still need to be explored. OBJECTIVE: To discuss the specificity and sensitivity of discoid lateral meniscal tears in children using morphological indexes. METHODS: Seventy-three patients (seventy-six knees) with torn discoid lateral meniscus underwentarthroscopy and MRI data of knee examinations were retrospectively reviewed. All MR images were double-blinded, independently, retrospectively analyzed by attending radiologist (doctor A) and sports physician (doctor B). The following morphological signs of discoid lateral meniscus, such as a internal displaced free edge sign, a hypertrophic free edge sign and a hypertrophied-horn sign, were selected to evaluate the discoid lateral meniscus tears. The likelihood of the discoid lateral meniscus tears was analyzed on basis of arthroscopic findings constituted the gold standard. Sensitivity, specificity and accuracy of MRI diagnosis of the discoid lateral meniscus tears by two physicians were calculated, and the consistency of diagnosis results by two physicians was evaluated using the Kappa statistics.RESULTS AND CONCLUSION: (1) The sensitivity, specificity and accuracy in the diagnosis of discoid lateral meniscustears by internal displaced free edge sign for doctor A were 19%, 94% and 53%, respectively, and for doctor B were 21%, 97% and 55%. (2) The sensitivity, specificity and accuracy in the diagnosis of discoid lateral meniscus tears by hypertrophic free edge sign for doctor A were 52%, 100% and 74%, respectively, and for doctor B were 57%, 97% and 75%. (3) The sensitivity, specificity and accuracy in the diagnosis of discoid lateral meniscus tears by hypertrophied-horn sign for doctor A were 26%, 97% and 58%, respectively, and for doctor B were 24%, 100% and 58%. (4) The sensitivity, specificity and accuracy in the diagnosis of discoid lateral meniscus tears by binding morphological index for doctor A were 86%, 91% and 87%, respectively, and for doctor B were 88%, 94% and 91%. (5) The Kappa statistics for discoid lateral meniscus tears respectively demonstrated a good inter-observer agreement (K > 0.75, P < 0.001). (6) These findings suggest that single morphological index used to evaluate the discoid lateral meniscus tears shows a good specificity, but which also shows a low sensitivity, while a binding morphological index can significantly improve the diagnostic sensitivity. Morphological characteristics may be reliable indexes to evaluate the discoid lateral meniscal tears in children.
