Objective To explore the feasibility of using the consensus of European Working Group on Sarcopenia in Older People(EWGSOP) to diagnose sarcopenia among community-dwelling women aged from seventy to seventy-nine in Shanghai.Methods Twenty-two healthy community-dwelling women were recruited as the subject group(group S),and another ten young girls were randomly selected as the control group(group C).The anthropometry,bioelectrical impedance analysis(BIA)and dual energy X-ray absorptionmetry(DEXA)were used to evaluate the circumferences of upper and lower limbs,and the dimension of muscle mass,according to relative appendicular skeletal mass(RASM)and skeletal muscle index(SMI).The grip dynamometer and isokinetic dynamometer were used to measure the muscle strength of upper and lower limbs.The ten meters gait speed,functional reach test,timed up and go test,Berg balance scale and short physical performance battery were all applied to assess the physical performance.The criteria of EWGSOP consensus were applied to diagnose the situation of sarcopenia.Results Firstly,the average biceps circumference and fat mass of upper limbs in group S were significantly higher than group C (P＜0.01),while no significant differences were observed in the muscle mass(P＞0.05).Secondly,RASM values gained from BIA and DEXA in S group were significantly higher than C group(P＜0.05),while the SMI values of the former were significantly lower than the latter(P＜ 0.01).Thirdly,absolute grip strength,relative grip strength and other bio-mechanical indexes of lower limbs in the s group were significantly lower than the C group(P＜0.01);the relative grip strength showed significant correlation with most bio-mechanical indexes of lower limbs.Fourthly,the physical performance in group S declined significantly compared with that of the c group(P＜O.05),and no significant correlation was found between muscle strength and physical performance of upper limbs except the absolute grip strength and gait speed.The prevalence was 0％ according to the RASM index,while the prevalence was 63.6％ and 45.4％ according to the BIA and DEXA respectively.Conclusion The assessing pattern from EWGSOP consensus could not be simply copied to applying on Chinese old people due to serious difference between RASM and SMI.The combination of SMI+relative grip strength+ TUG/SPPB/Berg may be better than the classical mode of RASM+absolute grip strength+gait speed in diagnosing sarcopenia.

Objective To investigate the CT manifestations of gastric carcinoma invasion to lesser omentum and to assess the im-pact of lesser omentum on the spreading of gastric carcinoma.Methods We retrospectively reviewed CT findings in 48 patients with gastric carcinoma and lesser omentum involved for primary tumor and the lesser omentum abnormalities.The influence of lesser o-mentum on the extension of gastric carcinoma as well as the accompanied ascites were also analyzed.Results CT manifestations of lesser omentum involvement in gastric carcinoma included the following items:① direct infiltration (35.4%,1 7/48),which was mainly shown as increased density of fatty tissue and the development of mass within the lesser omentum,including spreading into the liver through the lesser omentum directly in two cases;② omental seeding (25.0%,12/48),including smudged appearance (1 1 cases)and omental caking (1 case);③ metastasis of lymph nodes (64.6%,31/48),including enlargement and increase of lymph nodes (27 cases)and cystic mass (4 cases).Ascites was found in 1 1 patients and fluid collection in the lesser sac was shown in 3 of these 1 1 patients.The lesser omentum forms the anterior wall of the lesser sac and separates the fluid collection in the lesser sac from the ascites in the greater peritoneal cavity.Ascites was associated with the omental seeding statistically.Conclusion CT scan is helpful for detecting lesser omentum invasion by gastric carcinoma.The imaging features consist of mass sign,enlargement of lymph nodes,smudged andcakingappearance,and so on.Lesser omentum may also play a certain role in both the extension of gastric carcinoma and the compartmentalization of ascites due to gastric carcinoma.

Fibroblast growth factor-21 (FGF-21) is an important metabolism regulator, however, whether FGF-21 has effects on cardiovascular remains unclear. In this study, H2O2-induced injury in H9c2 cells was used as a cell model, the anti-apoptosis potential and mechanism of FGF-21 against oxidative injury were evaluated by MTT assay, flow cytometry assay and real-time PCR. The results showed that FGF-21 could increase the cell survival of H2O2-induced injury in H9c2 cells and prevent H9c2 cells from oxidative stress-induced apoptosis. Furthermore, FGF-21 can elevate SOD activity and regulate Bcl-2/Bax expression in H9c2 cells. The results suggest that FGF-21 have protective effect against the H2O2-induced apoptosis in H9c2 cells.

Objective To investigate the correlation between the expression of aryl hydrocarbon receptor(AHR) mR-NA and tryptophan dioxygenase (TDO) mRNA in bone marrow mononuclear cells of patients with acute leukemia.Methods Sixty-five patients with newly diagnosed acute leukemia in Henan Provincial People's Hospital from August 2013 to August 2014 were selected as observation group,and there were 50 patients with acute myeloid leukaemia(AML) and 15 patients with acute lymphoblastic leukaemia(ALL).Fifteen patients with anemia were selected as control group in the same period(excluding the malignant disease of blood system).The expression of AHR mRNA and TDO mRNA in bone marrow mononuclear cells of patients in the groups was detected by real time fluorescence quantitative reverse transcription polymerase chain reaction.The correlation between AHR mRNA and TDO mRNA was analyzed.Results The expression of TDO mRNA and AHR mRNA in bone marrow mononuclear cells of AML and ALL patients in the observation group was significantly higher than that in the control group(P ＜0.05).There was no significant difference in the expression of TDO mRNA and AHR mRNA in bone marrow mononuclear cells between AML and ALL patients (P ＜ 0.05).There was significantly positive correlation between the expression of TDO mRNA and AHR mRNA in bone marrow mononuclear cells of AML and ALL patients(r =0.801,0.922;P ＜ 0.05).The levels of white blood cell,hemoglobin,platelet and lactate dehydrogenase were not related to the expression of TDO mRNA and AHR mRNA in AML and ALL patients(P ＜ 0.05).Conclusion The expression of TDO and AHR in bone marrow mononuclear cells of acute leukemia patients is high,and the TDO-KYN-AHR pathway promotes the development of acute leukemia.

Objective:To analyze the correlation between cognitive impairment and cortical atrophy in elderly patients with asymptomatic carotid artery stenosis (ACAS).Methods:In this cross-sectional study, 40 consecutive elderly patients with ACAS treated in the Department of Neurology, Northern Jiangsu People′s Hospital from July 1, 2020 to June 30, 2021 (ACAS group), and 40 elderly healthy controls who accepted physical examination during the same period (control group) were included. Cognitive assessment was performed using the Mental State Examination Scale (MMSE) and the Montreal Cognitive Assessment Scale (MoCA), and brain magnetic resonance imaging scanning was performed in the ACAS group. The artificial intelligence technique was applied for brain lobe segmentation and cortical volume calculation. The χ2-test, independent sample t-test and Wilcoxon non-parametric test were used to analyze the difference of clinical data and cognitive scores between the two groups. In the ACAS group, the cortical volumes of the side with carotid stenosis was compared with that of the normal side, and Spearman′s correlation analysis was used to assess the correlation between cognitive scores and cortical atrophy. Results:Compared with the control group, the ACAS group got significantly lower scores of MMSE and MoCA, as well as lower scores of visuospatial executive function, attention and calculation, language function, abstraction ability and delayed recall [(25.60±2.49) vs (27.18±1.01), (22.05±3.59) vs (25.60±1.43), (2.73±1.04) vs (4.08±0.62), (4.53±0.93) vs (5.03±0.66), 2.00 (0.00) vs 3.00 (0.00), 1.00 (1.00) vs 2.00 (0.00), and (2.95±0.96) vs (3.35±0.62)] (all P<0.05). There was not significant differences in naming and orientation ability between the two groups (both P>0.05). The volume of cortical, temporal lobe, frontal lobe, parietal lobe and insular lobe on the side with carotid stenosis in the ACAS group were significantly smaller than those on the normal side [186.23 (177.97, 202.53) vs 194.67 (185.65, 204.82) cm 3, 54.74 (50.66, 56.95) vs 55.61 (51.24, 58.49) cm 3, 72.98 (70.76, 78.34) vs 75.27 (72.34, 80.66) cm 3, 53.66 (51.11, 57.86) vs 56.59 (52.80, 60.09) cm 3, 6.57 (6.35, 7.07) vs 6.72 (6.46, 7.34) cm 3] (all P<0.05). The MoCA score in the ACAS group was positively related to the cortical volume ratio of the two sides ( r=0.427, P<0.01). The attention ( r=0.353) and abstraction ( r=0.226) ability scores were positively correlated with the temporal lobe volume ratios of the two sides (both P<0.05). The visuospatial executive ( r=0.187) and language ( r=0.373) ability scores were positively correlated with frontal lobe volume ratios of the two sides (both P<0.05), and visuospatial executive ( r=0.386), naming ( r=0.344), language ( r=0.517), abstraction ( r=0.335) and delayed recall ( r=0.333) ability scores were positively correlated with parietal lobe volume ratios of the two sides (all P<0.05). Conclusion:In elderly patients with ACAS, the cognitive impairment and cortical atrophy on the sides with carotid stenosis are significant and a positive correlation is detected between them.

Objective To explore the correlations between monocyte immunodepression andthe levels of C-reactive protein (CRP) and fibrinogen (Fg) in patients with severe acute stroke. MethodsThis prospective study involved 53 consecutive patients admitted in the neurological intensive care unit(NICU) within 24 h after stroke onset. Blood samples were collected serially on days 1, 2, 4, 6 and 14after stroke to determine monocytic HLA-DR expression using flow cytometry. CRP and Fg weredetected on day 2 after the admission, and Graph_Pad PRISM 4.0 software was used to analyze thecorrelations among the variables. Thirty-nine concurrent patients admitted in the general ward, whocomplained dizziness without magnetic resonance imaging evidence of acute stroke, were enrolled toserve as the control group. Results The levels of CRP and Fg in the stroke group were significantlyhigher than those in the control group (P<0.05). The CRP and Fg levels were both found to inverselycorrelate to monocytic HLA-DR expression at different observational points. The correlations of CRP andFg to HLA-DR expression were the most obvious on day 2 and 4 after admission (r=-0.419, P=0.001;r=-0.434, P=0.001), respectively. Conclusion Immunosuppression of the monocytes in patients withsevere acute stroke is probably associated with the inflammatory reaction after stroke.

OBJECTIVETo compare the outcomes of intracytoplasmic sperm injection (ICSI) with retrieved epididymal and testicular sperm for obstructive azoospermia and with ejaculated sperm for severe oligozoospermia and asthenospermia.

METHODSWe retrospectively analyzed 431 ICSI cycles, which were divided according to sperm sources into Groups A (n=287 in patients with severe oligozoospermia or asthenospermia using ejaculated sperm), B (n=109 in obstructive azoospermia patients with sperm retrieved by percutaneous epididymal sperm aspiration, PESA) and C (n=35 in obstructive azoospermia patients with sperm retrieved by testicular sperm extraction, TESE). Comparisons were made among the three groups in the rates of embryo implantation, fertilization, pregnancy, cleavage, and miscarriage.

RESULTSGroup A showed statistically significant differences from Groups B and C in the rates of embryo implantation and pregnancy (18.46% vs. 25.23% and 28.76%, 31.23% vs. 42.16% and 39.39%, P < 0.05). But no significant differences were seen in the rates of fertilization, cleavage and miscarriage among the three groups (P > 0.05).

CONCLUSIONThe rates of embryo implantation and clinical pregnancy are higher in patients with obstructive azoospermia than in those with severe oligozoospermia or asthenospermia after ICSI with ejaculated sperm.

OBJECTIVETo assess zero drift of intraventricular and subdural intracranial pressure (ICP) monitoring systems.

METHODSA prospective study was conducted in patients who received Codman ICP monitoring in the neurosurgical department from January 2010 to December 2011. According to the location of sensors, the patients were categorized into two groups: intraventricular group and subdural group. Zero drift between the two groups and its association with the duration of ICP monitor were analyzed.

RESULTSTotally, 22 patients undergoing intraventricular ICP monitoring and 27 receiving subdural ICP monitoring were enrolled. There was no significant difference in duration of ICP monitoring, zero drift value and its absolute value between intraventricular and subdural groups (5.38 d+/-2.58 d vs 4.58 d+/-2.24 d, 0.77 mm Hg+/-2.18 mm Hg vs 1.03 mm Hg+/-2.06 mm Hg, 1.68 mm Hg+/-1.55 mm Hg vs 1.70 mm Hg+/-1.53 mm Hg, respectively; all P larger than 0.05). Absolute value of zero drift in both groups significantly rose with the increased duration of ICP monitoring (P less than 0.05) while zero drift value did not. Moreover, daily absolute value in the intraventricular group was significantly smaller than that in the subdural group (0.27 mm Hg+/-0.32 mm Hg vs 0.29 mm Hg+/-0.18 mm Hg, P less than 0.05).

CONCLUSIONThis study demonstrates that absolute value of zero drift significantly correlates with duration of both intraventricular and subdural ICP monitoring. Due to the smaller daily absolute value, ICP values recorded from intraventricular system may be more reliable than those from subdural system.
