Objective To analyze the clinical feature and diagnostic methods of patients with ischemic colitis(IC) for improving the recognition and the efficacy of therapeutic treatment. Methods Retrospective analysis of the clinical data of 30 cases of IC,including the medical history,clinical symptomatology,endoscopic appearance, histopa-thology,treatment and prognosis. Results IC occurred most of frequently in mid-aged and elders,the male-female ra-tio was 1:2.3,83.3% of the patients were over 60 years old, and most them had underlying disease. The most com-mon presenting features were sudden abdominal pain and bloody stools. Endoscopic lesions located mainly in left co-lon. Mucosal edema,erosin and submucosal bleeding were common pathological feature. Vasodilator drugs and compre-hensive medical therapy had good effects. The average duration for healing or improving was 10 days. Conclusions IC should be suspected in all elder patients with sudden abdominal pain and bloody stools. Colonoscopy is helpful for diagnosis. The prognosis is good in most cases and with rapid recovery.

Objective To explore the diagnostic value of "Standard" EEG,which include common induced test with sleeping induce(1.5 to 2.0 h) and choice sphenoidal electrode description in epilepsy.Methods 236 epileptic patients were inspected with routine,standard EEG early and late, and then they were diagnosed primarily and once more.Results The epileptic discharges positive rate(81.36%) of standard EEG was higher than routine EEG (29.66%),(P

Objective To explore neuronal damage in epileptic patients after seizures.Methods The serum and cerebrospinal fluid (CSF) levels of neuron-specific enolase (NSE) in the epileptic patients were dynamically determined after seizures by enzyme-linked immuno-sandwich assy. Results The serum and CSF levels of NSE in the epileptic patients were markedly increased after seizures. The serum levels of NSE peaked 1 day after seizure, decreased about one week later,and then returned to normal after two weeks or so. The serum and CSF levels of NSE were much higher in the epileptic patients with tic or frequency.Conclusion NSE in serum and CSF could reach higher levels after seizures, suggesting that neuronal damage may result from seizures,especially when tic and frequency occur.

【Objective】 To analyze the correlation between thromboelastogram(TEG) index and postoperative bleeding in patients underwent percutaneous nephrolithotomy, thus providing evidence for clinical treatment and prevention. 【Methods】 The clinical data of 90 patients suffered from percutaneous nephrolithotomy were collected for a retrospective study. According to the presence or absence of bleeding, they were divided into non-bleeding group (n=71) and bleeding group (n=19).1) The clinical data, including gender, age, operation time, glomerular filtration rate (GFR), stone length, stone width, stone CT value, white blood cell count (WBC), hemoglobin (Hb), platelet count (Plt), neutrophil ratio, prothrombin time (PT), international normalized ratio (INR), activated partial thromboplastin time (APTT), D2 polymer, procalcitonin (PCT), interleukin-6 (IL-6), and TEG indicators (R value, K value, MA value, and angle), of the bleeding group and the non-bleeding group were compared. 2) The risk factors of postoperative bleeding in patients underwent percutaneous nephrolithotomy were analyzed. 3) The K, MA, R value, angle and ROC curve of the combined index were analyzed. 【Results】 There was no significant difference in gender, age, operation time, stone length, stone width, WBC, Plt, neutrophil ratio, PT, INR, APTT, R value between the two groups (P>0.05). General data of the two groups, including GFR, CT value of stones, Hb, D2 polymer, PCT, IL-6, K value, MA value, and angle, were statistically different (P<0.05). Binary logistic regression analysis showed that the decrease of Hb and K value, and the increase of angle were independent factors in the prediction of postoperative bleeding in patients underwent percutaneous nephrolithotomy (P<0.05). Correlation analysis displayed that Hb was positively related to K and R value, and negatively correlated with MA value and angle (r=0.508/0.391/-0.349/-0.548, both P<0.05); ROC curve analysis indicated the AUC of K value: (0.707, P<0.05), 0.416 of Youden index, 89.50% of sensitivity, and 52.10% of specificity; the AUC of MA value: (0.618, P>0.05), 0.303 of Youden index, 89.50% of sensitivity, and 40.80% of specificity; AUC value of angle: (0.720, P<0.05), 0.430 of Youden index, 89.50% of sensitivity, and 53.50% of specificity; AUC of R value: (0.610, P>0.05), 0.377 of Youden index, 84.20% of sensitivity, and 53.50% of specificity; AUC value of the combined index: (0.696, P<0.05), 0.384 of Youden index, 94.70% of sensitivity, and 43.70% of specificity. 【Conclusion】 TEG indicators can assess the coagulation function of patients underwent percutaneous nephrolithotomy, predict the risk of postoperative bleeding, and help guide clinical postoperative treatment.

AIM: To investigate the relationship between the levels of chemokine receptor 2(CXCR2)and basic fibroblast growth factor(bFGF)in aqueous humor and the prognosis of trabeculectomy in patients with acute primary angle-closure glaucoma(APACG).METHODS: A total of 80 cases(80 eyes)APACG patients who underwent trabeculectomy in our hospital from June 2020 to January 2022 were collected in the case group. According to the postoperative efficacy, they were grouped into a success group of 60 cases(60 eyes)and a failure group of 20 cases(20 eyes). Another 86 cataract patients(86 eyes)who underwent phacoemulsification with normal intraocular pressure in our hospital during the same period were included in the control group. Enzyme linked immunosorbent assay was applied to detect the levels of CXCR2 and bFGF in aqueous humor. ROC curve was applied to analyze the value of predicting trabeculectomy failure in APACG patients by the levels of CXCR2 and bFGF in aqueous humor. Furthermore, multivariate Logistic regression was applied to analyze the influencing factors of trabeculectomy failure in APACG patients.RESULTS: The levels of CXCR2 and bFGF in the aqueous humor of the case group were significantly higher than those of the control group(P<0.05). The levels of CXCR2 and bFGF in the aqueous humor of the failed group and the proportion of patients with postoperative shallow anterior chamber were significantly higher than those of the successful group(P<0.05). The AUC for predicting trabeculectomy failure in APACG patients using CXCR2 and bFGF levels alone and in combination was 0.885, 0.883 and 0.953, respectively. CXCR2 and bFGF were independent risk factors for trabeculectomy failure in APACG patients(P<0.05).CONCLUSION: The levels of CXCR2 and bFGF in the aqueous humor of APACG patients are obviously elevated, and both are risk factors for trabeculectomy failure.

Objective To compare percutaneous suturing with sponge forceps and open suturing for repair of acute closed Achilles ruptures.Methods From March 2011 to June 2014,40 patients with acute closed Achilles rupture were enrolled in this study and randomized into 2 equal groups (n =20) which were subjected to percutaneous suturing with sponge forceps or open suturing.The operative time,incisive length,blood loss,wound healing,hospitalization time and complications were compared between the 2 groups.Their ankle functions were evaluated at postoperative 3,6,and 12 months according to American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores.Results The operative time (median,60.0 min),hospitalization time (median,8.5 d) and incisive length (median,8.0 cm) in the open suturing group were significantly greater than those in the sponge forceps group (32.5 min,7.0 d and 1.5 cm) (P ＜ 0.05).The blood loss (15.1 ± 13.7 mL) in the sponge forceps group was significantly less than in the open suturing group (54.2 ± 33.9 mL) (P ＜ 0.05).The open suturing group received an average follow-up of 16.8 months (from 12 to 23 months),witnessed superficial skin infection in 3 cases,and obtained AOFAS scores of 91.2 ± 5.1,95.2 ± 2.8 and 97.8 ± 1.6 at 3,6,and 12 months postoperatively.The sponge forceps group received an average follow-up of 15.6 months (from 12 to 24 months),witnessed wound healing in all cases,and obtained AOFAS scores of 90.6 ±5.3,94.I ±2.6 and 97.0 ±2.6 at 3,6,and 12 months postoperatively.The sponge forceps group obtained insignificantly lower AOFAS scores than the open suturing group (P ＞ 0.05).No injury to the sural nerve or tendon rerupture happened in either group.Conclusions In treatment of acute closed Achilles ruptures,compared with open suturing,percutaneous suturing with sponge forceps may be relatively easier without using special equipment,and additionally,may lead to lower incidence of incision complications and better short-term efficacy.

Objective To observe the therapeutic effects of Cheneau orthosis with different pressure areas on the patients with adolescent idiopathic scoliosis. Methods Thirty patients with adolescent idiopathic scoliosis who had apex vertebraes below T6 were included, and randomly divided into group A in which patients wore orthosis spanning across 3 vertebra, and group B in which patients wore orthosis spanning across 5-6 vertebra. All patients were assessed with regard to Cobb degree, apex vertebrae rotary degree and pain index after wearing the orthosis. Results The rectified ratio of Cobb degree were 17% and 29% in groups A and B, respectively. There was a statistical difference between the 2 groups(P<0.05). No statistical difference was found between the 2 groups in terms of apex vertebrae rotary degrees(P>0.05). Pain index was 5.00 in group A, and 2.07 in group B, which was statistically different (P<0.05). Conclusions Increasing pressure points' areas of Cheneau orthosis properly can improve more effectively the lateral curvature angle of the patients with adolescent idiopathic seoliosis.

Objective To understand the etiological characteristics and risk factors of respiratory virus infection in children with bronchial asthma, and to provide theoretical basis for the prevention and treatment of respiratory virus infection in children with bronchial asthma. Methods A total of 374 children with bronchial asthma who were treated in Jianyang People's Hospital from December 2018 to December 2020 were enrolled. Pharyngeal swabs were collected from the outpatient children on the day of treatment, and 2 mL of nasopharyngeal secretions were collected from the hospitalized children within 24 hours by negative pressure aspirator. Seven viral antigens including RSV, ADV, IVA, IVB, PIVI, PIV II, and PIV III were detected. According to whether the virus test results were positive or not, they were divided into the experimental group (n=191) and the control group (n=183). Logistic regression analysis was used to screen the risk factors of respiratory virus infection in children with bronchial asthma. Results Among the 374 samples, the virus positive rate was 51.07% (191/374), and the top 3 virus species in the positive samples were RSV, ADV, and PIV III, accounting for 41.36% (79/191), 30.36% (58/191), and 9.42% (18/191), respectively. In addition, IVA accounted for 5.24% (10/191), PIV II accounted for 5.24% (10/191), PIVI accounted for 3.66% (7/191), and IVB accounted for 1.57% (3 /191). The positive rates of virus were 47.96% (94/196) and 54.49% (97/178) in male and female children, respectively, with no significant difference (χ²=1.597，P>0.05). The positive rate of 1~3 years old children was significantly higher than that of >3 years old group (χ²=6.412，P<0.05). There were significant differences in the frequency of asthma attack, intravenous glucocorticoid application and the onset season between the two groups (P<0.05). Further analysis showed that the frequency of asthma attack >3 times, intravenous glucocorticoid application and onset season were independent risk factors for respiratory virus infection in children with bronchial asthma (P<0.05). Conclusion The infection season of acute respiratory tract infection in children with asthma is mainly concentrated in autumn and winter, with RSV as the main viral pathogen. Targeted preventive measures should be given to children with bronchial asthma who have more than 3 asthma attacks and intravenous glucocorticoid application, which can reduce respiratory virus infection in children with asthma.

Objective To verify BMP-2 and VEGF gene activated nanobone paste can effectively enhance the vertebral bone of ovariectomized goat.Methods From January,2011 to May,2016,the goats had been neutered by ovariectomy 6 months earlier to induceosteoporosis.Then surgery to established the model of vertebral bone defected with nanobone implanting,and the operation vertebrae divided randomly into 3 groups:control group,nanobone group and double gene activated nanobone group.Three months after operation the goats were sacrificed and removed the vertebrae.Micro CT analysis of micro three-dimensional structure of trabecular bone,scanning electron microscope (SEM) analysis of the two-dimensional structure of the vertebrae,the structure of trabecular bone was evaluated by movat pentachrome staining.Results The dual gene activated nanobone group compared with the nanobone group,the bone volume fraction (BV/TV) significantly increased (85％ at 1.2 mm vs 43％ at 1.2 mm,P ＜ 0.05);the dual gene activated nanobone group compared with nanobone group,in the largest ROI (1.2 mm),TbTh increased 10.9％ (374 ± 26.2 μm vs 337 ± 22.3 μm,P ＜ 0.05);Trabecular distribution coefficient (TbPf) was significantly decreased (7.519 ± 0.184 mm-1 vs 7.529 ± 0.261 mm-1,P ＜ 0.05);In the largest ROI (0.8 mm),trabecular distribution coefficient (TbPf) was significantly decreased (283 ± 36.4 μm vs 327 ± 31.2 μm,P ＜ 0.05),In the largest ROI (0.8 mm),the trabecular bone volume (Tbn) was increased 20％(1.404 ± 0.283 mm-1 vs 1.173 ± 0.224 mm-1,P ＜ 0.05);Cortical thickness over the implantation area showed asignificant increase of 43％ in vertebrae(P ＜ 0.05);The histological analysis revealed a more extensive osseointegration of the dual gene activated nanobone group,with the presence of anabundant osteoid tissue and an osteoblastic celllining.Conclusion BMP-2 and VEGF gene activated nano bone paste can effectively enhance the vertebral bone of ovariectomized goat.

Objective To explore the relationship between glucose-6-phosphate dehydrogenase deficiency and type 2 diabetes and to provide reference for clinical diagnosis,monitoring and treatment of Type 2 diabetes.Methods Subjects were selected from our hospital,including 173 cases of healthy volunteers assigned to the control group;1 95 cases with type 2 diabetes conforming to the diagnostic criteria of WHO were assigned to the diabetic group.97 cases were diagnosed with glucose-6-phosphate dehydrogenase deficiency in our hospital,of whom 82 cases were assigned to simple glucose-6-phosphate dehydrogenase deficiency group,and 1 7 cases were assigned to the diabetes with glucose-6-phosphate dehydrogenase deficiency group.The correlation of glucose-6-phos-phate dehydrogenase activity and diabetes was measured by each detected value.Results Compared with the control group,the glu-cose-6-phosphate dehydrogenase activity and RBC count in diabetic group were higher(P <0.05).Positive correlations between glu-cose-6-phosphate dehydrogenase activity and RBC count in the two groups were significant(P <0.05).HbA1c and FBG showed a significant positive correlation in the control group,diabetic group and diabeties with glucose-6-phosphate dehydrogenase deficiency group(P <0.05).But there was no significant correlation in the glucose-6-phosphate dehydrogenase deficiency group.The rate of screening for glucose-6-phosphate dehydrogenase deficiency in diabetes group was 3.6%,and the rate in the control group was 1. 1%.When HbAlc≥6.5%,the rate of screening for glucose-6-phosphate dehydrogenase deficiency in the diabetes group was signifi-cantly higher than that in the control group (χ2 =4.239,P =0.039).Conclusion The level of HbA1c is discordant with that of blood glucose in diabetic patients with glucose-6-phosphate dehydrogenase deficiency group.Diabetes leads to the increasement of the rate of glucose-6-phosphate dehydrogenase deficiency.The glucose-6-phosphate dehydrogenase activity of diabetic patients with non-glucose-6-phosphate dehydrogenase dificiency is higher than that of the normal group.It may be associated with the level of RBC or increase of compensatory.Further more,glucose-6-phosphate dehydrogenase activity may be a good indicator for controlling diabetes,which remains to be further studied.
