Objective To explore the relationship between children obesity and adiponectin(ADPN),leptin(LP),and high-sensitive C-reactive protein(hsCRP).Methods Seventy-one obese volunteers as obesity group and 30 normal volunteers who matched obese volunteers in age and sex as control group were selected from 13 702 children and adolescents of 2 to 18 years old in Xiangtan city by sampling survey.The body mass index(BMI),ADPN,LP,hsCRP,fasting blood-glucose(FBG),and fasting pure insulin(INS) were checked respectively.The homeostasis model assessment for insulin resistance(HOMA-IR) and the quantitative insulin-sensitivity check index(QUICKI) were calculated.The difference between the two groups was compared and the relationship of all indexes was analyzed.Results The values of ADPN and QUICKI in obesity group were significantly lower than those of control group(P

Objective To explore the clinical effect of procedure for prolapse and hemorrhoids (PPH) treating for Ⅲand Ⅳ degree hemorrhoid under the local anesthesia.Methods One hundred and fifty patients with Ⅲ and Ⅳ degree hemorrhoid were divided into two groups randomly.One group was the local anesthesia group (LA group) which included 73 cases,the other one was the combined spinal epidural anesthesia group (CSE group) which included 77 cases.Compared the safety and efficacy of different procedure.Results The original symptom of the two groups were improved.There was a significant difference in the time of hospitalization time and the hospitalization expense between the two groups (P＜0.05).The LA group was(4.8±1.1)days with(3980±639)yuan,and the CSE group was(6.8±1.1) days with(5128±728)yuan.The rates of two groups of urine retention were 9.6% and 24.7% (P＜0.05) after the operation respectively,and there were no significant differences in recovery normal activity time,the pain index,copracrasia and pruritus,the bleed,the anal fistula,the prolapse of hemorrhoid,the skin tag (P ＞0.05).Conclusion PPH under the local anesthesia is safe,compare to the combined spinal epidural anesthesia,it excels in shortening the hospitalization time and reducing the hospitalization expense,also it can reduce significantly the rate of urine retention after operation.

Infectious bursal disease virus(IBD) causes infectious bursal disease (IBD), which infects bursal of chicken and can evoke immune suppression. This study identified the antigenic epitopes of four McAbs to IBDV VP3(HRB-3F, HRB-7B, HRB-7C and HRB-10E)with pepscan. A set of 17 partially overlapping or consecutive peptides (P1-P17) spanning VP3 were expressed for epitope screening by pepscan. Finally, two antigenic epitopes, 109-119aa and 177-190aa of IBDV VP3, were identified by Western blot and ELISA. The peptides on epitopes could react with IBDV, and they had better immunnogenicity. The sequences of epitopes were compared with that of several other IBDV strains in the same region, and was found they were totally homologous. This study showed the two epitopes were novel conserved linear B cell epitopes on the VP3 of IBDV. This study provides basis for the development of immunity-based prophylactic, therapeutic and diagnostic measures for control of IBD and further for structural and functional analysis of IBDV.

OBJECTIVETo observe dynamically the development of fetal long bone and detect the expression and distribution of HIF-1alpha,to investigate the expression pattern and possible effects of hypoxia inducible factor-1alpha (HIF-1alpha) in fetal long bone development of mouse.

METHODSE12.5, E13.5, E14.5, E15.5, E16.5 and E17.5 pregnant C57BL6 mice were sacrificed. After sacrifice, the embryos were delivered by caesarean section. The development of fetal long bone was dynamically observed by stereoscopic microscope, and the distributional expression of HIF-1alpha protein was detected by using method of immunohistochemistry. The expression of HIF-1alpha mRNA and osteoblast marker gene at various stage were also detected by using methods of reverse transcription-polymerase chain reaction (RT-PCR).

RESULTSThe cartilaginous long bone began to form and joints outline arised at E13.5, then the primary ossification center was observed at E14.5, showing opaque ossification under stereoscopic microscope,and then the osteogenesis expanded and extended to both sides. Immunohistochemistry demonstrated lots of HIF-1alpha protein positive chondrcytes in the center of primary ossification at E14.5, then they decreased dramatically. HIF-1alpha mRNA expressed at high level from E13.5 to E15.5, and then decreased to low level.

CONCLUSIONFetal long bone development pattern appeared to be endochondral osteogenisis process, existing hypoxia microenviroment may increase HIF-1alpha mRNA expression and thus initiate the cascade of endochondral osteogenisis.

OBJECTIVETo investigate the effect of edaravone on expression of interleukin-1beta (IL-1beta), nuclear factor-kappaB (NF-kappaB) and neuron apoptosis in the juvenile rat hippocampus after status convulsion (SC).

METHODSOne hundred and ninety-five juvenile male Sprague-Dawley (SD) rats were randomly divided into normal saline (NS) control group, status convulsive group and edaravone treatment group. Each group was further divided into five subgroups for different time points. The rats in status convulsive group were kindled into epilepsy by lithium-pilocarpine chemical method. Expressions of IL-1beta and NF-kappaB proteins were detected with immunohistochemistry methods. Expression of NF-kappaB mRNA was detected with reverse transcription-polymerase chain reaction (RT-PCR). The neuron apoptosis was observed by TdT-mediated dUTP nick end labeling (TUNEL).

RESULTS(1) Measured by immunohistochemistry the value of IOD of IL-1beta (30.83 +/- 3.81, 41.00 +/- 5.61, 36.32 +/- 6.78 and 28.48 +/- 4.61, respectively, 12-72 h points) and NF-kappaB (67.60 +/- 5.81, 74.61 +/- 7.94, 82.43 +/- 10.67, 70.70 +/- 5.85 and 68.22 +/- 9.67, respectively, 4-72 h points) positive cells in the SC group increased,there was significant difference compared with NS group (IL-1beta: 11.74 +/- 2.32, 12.93 +/- 2.49, 13.02 +/- 2.83 and 12.98 +/- 5.29, respectively, 12-72 h points. NF-kappaB: 48.67 +/- 16.14, 44.62 +/- 7.82, 53.16 +/- 114.45, 54.27 +/- 5.25 and 55.56 +/- 7.56, respectively, 4-72 h points) (P < 0.01, or P < 0.05). By ED intervention in IL-1beta (22.01 +/- 4.45, 28.28 +/- 4.50 and 26.00 +/- 5.34, respectively, 12-48 h points) and NF-kappaB (58.56 +/- 6.37, 59. 86 +/- 6.73, 70.00 +/- 10.09, 64.78 +/- 7.56 and 64.45 +/- 6.51, respectively, 4-72 h points) positive cells value of the IOD decreased as compared with SC group (P < 0.01, or P < 0.05). (2) Measured by RT-PCR, the expression of NF-KB mRNA and protein trend was similar. (3)The TUNEL positive cells in hippocampus, CA1 of SC group (11.41 +/- 2.37) were more than that of NS group 12 h after the SC (P < 0.01), reached its highest level at48 h (28.78 +/- 5.11), after the intervention with edaravone (8.98 +/- 2.22, 13.09 +/- 2.54 and 20. 57 +/- 4.89, respectively, 12-48 h points) ,TUNEL positive cells showed a significant drop in SC group at 12-48 h time points (P < 0.01, or P < 0.05), but still significantly higher than that of the NS group (6.22 +/- 1.50, 6.57 +/- 1.61 and 6.72 +/- 1.14, respectively) (P < 0.01, or P < 0.05), at the 4 h time point(NS group 6.29 +/- 1.49, SC group 6.61 +/- 1.71, ED group 5.75 +/- 1.41) among the three groups, no significant difference in TUNEL positive cells was found (P = 0.759).

CONCLUSIONSEdaravone inhibited expression of IL-1beta and NF-kappaB in pilocarpine-induced seizures in rat hippocampus, reduced the number of neuronal apoptosis. These results suggest that edaravone may have protective effect against the damage caused by status convulsion.

U-shaped sacral fractures are rare and often difficult to diagnose primarily due to the difficulty in obtaining adequate imaging and the severe associated injuries.These fractures are highly unstable and frequently cause neurological deficits.The majority of surgeons have limited experience in management of U-shaped sacral fractures.No standard treatment protocol for U-shaped sacral fractures has been available till now.This study aimed to examine the management of U-shaped sacral fractures and the early outcomes.Clinical data of 15 consecutive patients with U-shaped sacral fracture who were admitted to our trauma center between 2009 and 2014 were retrospectively analyzed.Demographics,fracture classification,mechanism of injury and operative treatment and deformity angle were assessed.All the patients were treated with lumbopelvic fixation or (and) sacral decompression.EQ-5d score was applied to evaluate the patients' quality of life.Of the 15 consecutive patients with U-shaped sacral fracture,the mean age was 28.8 years (range:15-55 years) at the time of injury.There were 6 females and 9 males.The mean followup time was 22.7 months (range:9-47 months) and mean full weight-bearing time was 9.9 weeks (range:8-14 weeks).Ten patients received lumbopelvic fixation and sacral decompression,one lombosacral fixation,and 4 merely sacral decompression due to delayed diagnosis or surgery.The post-operation deformity angle (mean 27.87°,and range:8°-90°) of the sacrum was smaller than that pre-operation (mean 35.67;range:15-90) with no significance difference noted.At the latest follow-up,all patients obtained neurological recovery with different extents.Visual analogue score (VAS) was reduced from preoperative 7.07 (range:5-9) to postoperetive 1.93 (range:1-3).All patients could walk without any aid after treatment.Eight patients were able to care for themselves and undertook some daily activities.Five patients had returned to work full time.In conclusion,lumbopelvic fixation is an effective method for stabilization of U-shaped sacral fractures with fewer complications developed.Effective reduction and firm fixation are the prerequisite of early mobilization and neurological recovery.Sacral decompression effectively promotes neurological recovery even in patients with old U-shaped sacral fractures.

navirus disease 2019 (COVID-19) in the patients younger than 18 years old infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant, and to provide a basis for determining the chest CT changes and efficacy of COVID-19 caused by Omicron virus variant in patients younger than 18 years old. Methods　The clinical and imaging data of 30 cases of patients younger than 18 years old infected with COVID-19 Omicron variant, who admitted to the Third People's Hospital of Shenzhen from February 11 to March 26, 2022 were collected and retrospectively analyzed. The clinical manifestations, imaging features and dynamic changes of lesions were summarized. Results A total of 41 intrapulmonary lesions in 30 patients with COVID-19 caused by SARS-CoV-2 Omicron variant. The main manifestations were patchy or nodular ground-glass opacities and/or consolidation, with focal subpleural distribution, lesions mainly occur in the right lung (70.73%, 29/41). There were 42 lesion morphologies, with 22 (52.38%) striped shadows and 16 (38.10%) nodular shadows, with small lamellar and patchy shadows predominating. There were 36 lesion density variations, with ground glass shadows being the most common, with a total of 24 ground glass shadows (66.66%) in each lobe of the lung, and also 6 consolidation lesions (16.67%) and 6 mixed ground glass opacity and consolidation lesions (16.67%). With the progression of the disease, lesions gradually enlarged, appeared on the 2nd day (312.93 mm3), peaked on the 9th day (1 837.18 mm3). The average absorption time of the lesions was (16±3) days, and there was no significant difference between the absorption time of patchy and nodular lesions (ground glass and/or consolidation) (t=0.853, P>0.05). The lesions showed focal ground-glass opacity in the early stage, 77.78% lesions were absorbed after treatment in the late stage. Inflammatory nodules were absorbed slowly (9-19 days), without residual fibrotic changes. Conclusions　The imaging manifestations of COVID-19 in patients younger than 18 years old infected with SARS-CoV-2 Omicron variant have certain characteristics, showed patchy or nodular ground glass opacities and/or consolidation, mainly distributed in the subpleural area, with small and few lesions and slow change, didn't remain fibrosis. Being familiar with its clinical and imaging manifestations can assist in early diagnosis, but confirming the diagnosis requires a combination of epidemiological history, clinical symptoms, SARS-CoV-2 nucleic acid and radiological manifestations.

OBJECTIVETo investigate the relation of heparanase gene and angiogenesis with the progress of gastric carcinoma (GC).

METHODSExpression of heparanase mRNA in 52 GC tissue was detected by in situ hybridization assay. Microvessel density (MVD) was examined by immunohistochemical method. MVD and heparanase mRNA expression were analysed with their relation to histological grade, invasion depth,lymph node metastasis and organ metastasis.

RESULTSMVD was 73.2 +/- 22.8 in 25 (48.1%) tissue with positive heparanase mRNA. It was 44.8 +/- 11.9 in 27 (51.9%) tissues with negative heparanase mRNA, between which the difference was significant (P < 0.001). MVD and heparanase mRNA expression were related with lymph node metastasis and depth of serosal invasion in GC (P < 0.005).

CONCLUSIONHeparanase, being related to angiogenesis in gastric cancer, promotes growth, invasion and metastasis. Heparanase mRNA expression is an important predictor of the biological behavior of human gastric carcinoma.
