Objective To investigate the effect of patient positioning on the Duplex ultrasound evaluation of great saphenous vein reflux elicited by the pneumatic cuff method. Methods FFifty great saphenous veins (GSV) with relfux (relfux group) and iffteen with no prior history of venous disease (healthy group) were examined by duplex scanning in the supine, 20 degrees reverse-trendelenburg (RT-20), 40 degrees reverse-trendelenburg (RT-40) and standing position. Each GSV was assessed for relfux at three venous sites:two centimeter below the sapheno-femoral junction (SFJ), the greater saphenous vein in the mid thigh (MGV) and the greater saphenous vein in the upper calf (CGV). Pneumatic cuff compression pressure of conifned 100 mmHg (1 mmHg=0.133 kPa) was used onto the calf to elicit relfux. The incidence of positive venous relfux was calculated. The statistical differences of the peak relfux velocity and duration of relfux in four positions were analyzed. Results TThe relfux elicited in the standing position was set as the gold standard. In healthy group, there was no false positive results of relfux in supine, RT-20 and RT-40 positions. In relfux group, false negative results were found at all venous sites when limbs were examined in supine position [false negative rate:59%(19/32), 22%(11/50), 24%(12/50)]. At RT-20 and RT-40 positions, the incidence of venous relfux reached 100% at MGV and CGV, and false negative cases were only detected at SFJ [false negative rate:12%(4/32), 12%(4/32)]. The relfux time in standing, supine, RT-20 and RT-40 positions were (7.75±3.23) s, (5.27±3.66) s, (8.67±3.72) s, (8.55±3.93) s respectively. There were signiifcant differences among different positions in reflux time (F=56.9, P<0.01). In detail, no significant differences were identified between standing position and RT-20 or RT-40 position (q=1.51, 1.33 respectively, both P > 0.05), except for supine position (q=4.11, P<0.01). Peak relfux velocity in standing, supine, RT-20 and RT-40 positions were (55.26±22.24) cm/s, (22.87±12.03) cm/s, (38.46±16.30) cm/s, (45.13±19.21) cm/s respectively. There were also signiifcant differences among different positions in peak relfux velocity (F=13.7, P<0.01). Comparing the supine, RT-20 and RT-40 positions with standing position, differences of the peak relfux velocity between them were all statistically signiifcant (q=12.71, 6.59, 3.98 respectively, all P<0.01). Conclusions When GSV reflux was examined by pneumatic cuff compression, false negative rate was higher in the supine position. RT-20 and RT-40 position were effective to detect GSV relfux, espically for GSV at mid-thigh and upper calf.

Objective To analyze the effects of Ileus tube (IT) along with somatostatin (SS) used for treatment of patients with severe acute pancreatitis (SAP).Methods Under conventional treatment,75 patients with SAP were divided into three groups as per different additional treatments,namely group A (IT and SS),group B (nasogastric decompression tube and SS),and group C (IT alone),and the therapeutic efficacies of those treatments were evaluated in respects of improvement of physical signs and symptems,dynamic changes in decompression drainage and prognosis.Results Therapeutic efficacy was 100％ in group A,84％ in group B and 80％ in group C.The difference between group A and B was x2 =8.26 (P ＜0.01) ; group B vs.C was x2 =0.38 (P ＞ 0.05).The physical signs and symptoms in group A were improved more rapid than those in group B and C (P ＜ 0.05),but there was no significant differences in those signs and symptoms between group B and group C (P ＞ 0.05).In comparison of decompression drainage,the t value of group A vs.group B was 2.14,group B vs.group C was 3.83,and group A vs.group C was 2.23 (P ＜ 0.05).As cure rate of patients with SAP in hospital on the 14th day,rate of transferring to surgical treatment as a last resort and mortality in group A were compared with group B and C,the differences were statistically significant (P ＜ 0.05),while group B vs.C,the difference was not statistically significant (P ＞ 0.05).Conclusions Application of IT combined with SS can significantly improve the condition of patients with SAP,thereby reducing the operation rate,shortening hospital stay,lowering mortality and improving the outcome,and it is worthy of clinical popularization.

BACKGROUND:Intra-articular injection of sodium hyaluronate or dexamethasone can relieve pain and increase range of motion after traumatic arthritis. OBJECTIVE:To observe the effect of dexamethasone combined with sodium hyaluronate on traumatic arthritis of rat knees. METHODS:Forty-eight Sprague-Dawley rats were randomly divided into four groups. The anterior ligament of the left knee was resected and the medial meniscus was removed to establish models of traumatic arthritis in al the rats. After 3 weeks, the four groups were respectively injected dexamethasone+sodium hyaluronate (combined group), dexamethasone, sodium hyaluronate, and nothing (control group). After 4, 8, 12 weeks of injection, the samples were obtained for gross observation, anteroposterior and lateral X-ray films and hematoxylin-eosin staining. RESULTS AND CONCLUSION:At 12 weeks after injection, X-ray films showed that there was no stenosis in the combined group, mild stenosis in the dexamethasone and sodium hyaluronate groups, and obvious stenosis in the control group (indicating severe osteoarthritis);hematoxylin-eosin staining exhibited the fibrous cartilage-like tissue grew wel in the combined group, varying degrees of proliferation of fibrous cartilage-like cells were visible in the dexamethasone and sodium hyaluronate groups, and there was a smal amount of fibrosis in the control group. These findings suggest that the combination of dexamethasone and sodium hyaluronate can improve the cartilage repair and restore the joint function.

Objective Increasing evidence supports the involvement of autophagy in the etiopathology of autoimmune diseases.Systemic lupus erythematosus (SLE) is a potentially fatal autoimmune disease characterized by production of multiple autoantibodies through poorly understood mechanism.In order to explore the role of autophagy in the development of SLE,the expression of autophagy related gene microtubule-associated protein 1 light chain 3 (MAPLC3) in peripheral blood mononuclear cells (PBMCs) was measured in patients with SLE.Methods The mRNA levels of LC3 in PBMCs from 56 SLE patients and 45 healthy individuals were detected by real-time quantitative polymerase chain reaction (qPCR) technique.Autophagy in PBMCs was also determined by flow cytometry (FACs) in 20 SLE patients and 15 healthy controls.The correlation between LC3 mRNA expression and disease activity of SLE (SLEDAI) was then analyzed.Results The mRNA level of LC3 (RQ) in SLE patients was obviously downregulated compared with that in healthy population (1.30 ± 0.10 vs 1.35 ± 0.09; P =0.029),paralleled with the decreased autophagy rate detected by flow cytometry in PBMCs of SLE patients [(2.21 ± 1.07) ％ vs (9.91 ±4.01) ％ ;P =0.047].Moreover,LC3 mRNA expression level was negatively correlated with SLEDAI (r =-0.337,P =0.023).However,when the clinical features of 27 SLE patients with decreased LC3 mRNA expression (RQ ＜ 1.351) were compared with those of other 29 SLE patients with normal or high LC3 mRNA expression (RQ ＞ 1.351),increasing rates of arthritis,serositis,hematological abnormalities were noted in patients with decreased LC3 mRNA expression yet without statistically significance.However,there was a significant difference between two groups in the incidence of renal involvement (P =0.028).Conclusion The impaired autophagy due to dowrnregulated LC3 mRNA level in SLE patients indicates that autophagy plays a role in mediating the occurrence and development of SLE.

The electronic structure of a Lindqvist type [Mo7O24]6- anion with 5 different types of counterion (K+, Na+, NH4+, [NH3Pr]+ and [NH3Pri]+) was calculated by using the Discrete Variational Method coupled with Density Functional Theory (DFT-DVM). It could be concluded through variance analysis to the calculated results that the type of counterion does not influence remarkably the electronic structure of [Mo7O24]6- anions. Perhaps it can be used to explain the experiment fact that the polyoxomolybdate structure of the Mo7O24 framework is apparently of critical significance to antitumor action. On these grounds we forecast that two other lindqvist type heptamolybadates(their counterions are Na+ and [NH3Pr]+ respectively) may also exhibit antitumor activities.

Objective: Envy, as a stable personality trait, can affect individuals’ mental health. Specifically, previous studies have found that envy can lead to depression; however, the mechanism by which envy affects depression is still unclear. Therefore, based on the resilience framework, we used structural equation modeling to explore the mediating roles that social support and psychological resilience play between envy and depression. Methods: Chinese college students (n=680) were recruited to complete four scales: the Dispositional Envy Scale (DES), the Symptom Checklist 90-Depression Subscale (SCL-90-DS), the Connor-Davidson Resilience Scale (CD-RISC), and the Perceived Social Support Scale (PSSS). Results: The results confirmed that both social support and psychological resilience are significant mediators between envy and depression. Furthermore, social support plays a significant mediating role between envy and psychological resilience, and psychological resilience plays a significant mediating role between social support and depression. Specifically, the results indicated that envy not only directly increases the likelihood of developing depression, but also indirectly increases the likelihood of developing depression by affecting psychological resilience through negatively influencing social support. Conclusion This study provides a theoretical basis for enhancing psychological resilience and social support in order to ameliorate adverse effects of envy on depression.

Objective To study the accuracy of real-time continuous monitoring system (RT-CGMS) at different stages and its association with glucose excursion. Methods Totally 33 patients with type 1 diabetes or type 2diabetes were under surveillance of RT-CGMS for 5 d. Capillary glucose values were measured 7 times daily.Correlation coefficient, error grid analysis (EGA), and Bland-Altman analysis methods were used to assess the correlation, accuracy and agreement of RT-CGMS at different stages and in general level; The mean amplitude of glucose excursion (MAGE) and the frequency of glucose excursion ( FGE ) were also calculated. Results ( 1 ) The correlation coefficient of RT-CGMS with capillary glucose values at fasting, postprandial stages, and in general level were 0.94,0.92, and 0.93 respectively( P＜0.01 ). (2) EGA showed that 98.82%, 98.39%, and 98.64% of the results fell in the A and B zones and 1. 18%, 1.61%, and 1.36% fell in the D zone respectively at fasting,postprandial stages, and in general level. There is no result fell in C and E zones. ( 3 ) The agreement analysis showed that RT-CGMS readings were in close agreement with capillary glucose values at fasting, postprandial periods, and in general level. (4)The MAGE at fasting, postprandial periods, and in general level were (3.57±2.66), (4.07±3.09), and (4. 02 ±3.04) mmol/L (P＞0. 05), (0±0. 5), (3± 1), and( 1 ±3) d for FGE (P＜0. 01 ).Conclusion RT-CGMS at fasting stage has higher accuracy than postprandial stage and general level, FGE at fasting stage is higher than postprandial stage and general level.

To analyze the antigenic and genetic characteristics of the influenza A (H3N2) virus in mainland China during the surveillance year of 2013-2014, the antigenic characteristics of H3N2 virus were analyzed using reference ferret anti-sera. The nucleotide sequences of the viruses were determined by Sanger dideoxy sequencing, phylogenetic trees were constructed with the neighbor-joining method, and the genetic characteristics of the viruses were determined in comparison to current vaccine strains. The results showed that most of the H3N2 viruses were antigenically closely related to the A/Victoria/361/2011 vaccine strain cell-propagated prototype virus (99.6%). Using the A/Texas/50/2012 egg isolate as the reference antigen, 15.1% of the viruses were found to be closely antigenically related to it, while 11.9% of strains were closely antigenically related to the egg-propagated epidemic strain, A/Shanghai-Changning/1507/2012. Phylogenetic analysis of HA genes indicated that the A(H3N2) viruses in this surveillance year were in the same clade, but no drug resistant mutation was identified in the NA genes. During the 2013-2014 influenza surveillance year, no significant genetic change was detected in either the HA or NA genes of the A(H3N2) viruses, while significant mutations were found in egg isolates resulting from their adaptation during propagation in eggs. The antigenic and genetic changes should be investigated in a timely manner to enable the selection of an appropriate vaccine strain in China.

OBJECTIVE: To explore the genetic basis of a fetus with ventricular septal defect (VSD) by using modified noninvasive prenatal testing (NIPT) for the detection of microdeletion syndromes. METHODS: Chromosomal karyotypes of the fetus and its parents were analyzed by G-banding technique. Next generation sequencing (NGS) was used to detect genomic copy number variations (CNVs) in cell-free fetal DNA. The results were verified by fluorescence in situ hybridization (FISH). RESULTS: The fetus and its parents all had a normal karyotype at 320-400 band level. NGS revealed a deletion of 1.30 Mb at 7q11.23 in the fetus, with a 93% overlap with that of Williams-Beuren syndrome (WBS). The father also had a deletion of 1.42 Mb at 7q11.23, with a 99% overlap with that of WBS. Modified NIPT also detected the 1.30 Mb deletion at 7q11.23 in the fetus. The result of FISH has confirmed the above results. CONCLUSION It is necessary to carry out genetic testing on fetuses with VSD. NGS can detect fetal microdeletion syndromes and help to trace their parental origin. The modified NIPT for fetal chromosomal microdeletions/microduplication syndromes is highly accurate.
