Objective To investigate the levels and clinical significance of serum microRNA(miR)-651 and miR-630 in patients with cervical cancer.Methods From June 2017 to May 2020,108 cervical cancer patients accepted by our hospital were collected as the cervical cancer group.Meantime,100 cervical intraepithelial neoplasia(CIN)patients treated in our hospital were regarded as the CIN group,and 110 healthy individuals who underwent physical examination were regarded as the control group.Real-time fluorescence quantitative PCR(qRT-PCR)was applied to detect serum levels of miR-651 and miR-630,while analyzing the relationship between serum miR-651 and miR-630 as well as clinical features and prognosis of patients.Results The serum levels of miR-651 and miR-630 in the cervical cancer group and CIN group were obviously lower than those in the control group(P<0.05),while the serum levels of miR-651 and miR-630 in the cervical cancer group were obviously lower than those in the CIN group(P<0.05).The expression levels of serum miR-651 and miR-630 were positively corre-lated(r = 0.542,P<0.05).The serum levels of miR-651 and miR-630 were related to HPV infection,differentia-tion,lymph node metastasis,and FIGO staging(P<0.05).The overall survival rate of patients with low levels of miR-651 and miR-630 was lower than that of patients with high levels.Cox regression analysis showed that,HPV infection,degree of differentiation,lymph node metastasis,FIGO staging,miR-651,and miR-630 were all influ-encing factors for the prognosis of cervical cancer patients(P<0.05).Conclusion The serum levels of miR-651 and miR-630 in cervical cancer patients decrease,which are related to HPV infection,differentiation,lymph node metastasis,FIGO staging,and prognosis.

Objective:To evaluate the value of 18F-FDG PET/CT for preoperative localization of epileptogenic foci in refractory epilepsy patients with negative MRI. Methods:Clinical data (550 lobes) of 55 epilepsy patients (38 males, 17 females, age (20.0±8.1) years) with negative MRI who underwent preoperative 18F-FDG PET/CT-MRI between January 2014 and June 2020 at the First Affiliated Hospital of Jinan University were retrospectively analyzed. The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of 18F-FDG PET/CT, video electroencephalogram (VEEG), PET/CT+ VEEG and PET/CT-VEEG for localizing epileptogenic foci were calculated using stereoelectroencephalography (SEEG) and the outcomes of at least 1 year of postoperative follow-up as reference standards. χ2 test was used to compare the efficiencies of different examination modalities for unilobar, multilobar and all patients. Results:The correct lateralization rate of epileptogenic foci was 92.6%(25/27) using PET/CT. The sensitivity, specificity, accuracy, PPV and NPV of PET/CT for localization of epileptogenic foci were 65.1%(54/83), 77.9%(364/467), 76.0%(418/550), 34.4%(54/157) and 92.6%(364/393), respectively. The sensitivities of PET/CT-VEEG for localization of epileptogenic foci in all patients and patients with multilobar epilepsy were higher than those of VEEG alone (75.9%(63/83) vs 45.8%(38/83), 68.6%(35/51) vs 31.4%(16/51); χ2 values: 15.80, 14.16, both P<0.001). The specificities of PET/CT+ VEEG for localization of epileptogenic foci in all patients and patients with unilobar epilepsy were higher than those of VEEG alone (97.6%(456/467) vs 94.6%(442/467), 97.9%(282/288) vs 94.1%(271/288); χ2 values: 5.66, 5.48; P values: 0.017, 0.019). The sensitivity of PET/CT-VEEG (PET/CT and VEEG concordance) for localization of epileptogenic foci was higher than that of PET/CT+ VEEG (PET/CT and VEEG discordance) (8/9 vs 28.4%(21/74); χ2=10.40, P=0.001), and its specificity and accuracy were higher than those of PET/CT-VEEG (PET/CT and VEEG discordance) (93.4%(57/61) vs 71.7%(291/406), 92.9%(65/70) vs 72.1%(346/480); χ2 values: 13.23, 13.96; both P<0.001). Conclusions:18F-FDG PET/CT can localize and lateralize epileptogenic foci in patients with negative MRI. The combination of 18F-FDG PET/CT and VEEG improves the sensitivity, specificity, and accuracy for epileptogenic foci detection. 18F-FDG PET/CT is more accurate in detecting epileptogenic foci when it is concordant with VEEG.

Objective:To predict the short-term postoperative recurrence status of patients with refractory temporal lobe epilepsy (TLE) by analyzing preoperative 18F-FDG PET images and patients′ clinical characteristics based on deep residual neural network (ResNet). Methods:Retrospective analysis was conducted on preoperative 18F-FDG PET images and clinical data of 220 patients with refractory TLE (132 males and 88 females, age 23.0(20.0, 30.2) years)) in the First Affiliated Hospital of Jinan University between January 2014 and June 2020. ResNet was used to perform high-throughput feature extraction on preprocessed PET images and clinical features, and to perform a postoperative recurrence prediction task for differentiating patients with TLE. The predictive performance of ResNet model was evaluated by ROC curve analysis, and the AUC was compared with that of classical Cox proportional risk model using Delong test. Results:Based on PET images combined with clinical feature training, AUCs of the ResNet in predicting 12-, 24-, and 36-month postoperative recurrence were 0.895±0.073, 0.861±0.058 and 0.754±0.111, respectively, which were 0.717±0.093, 0.697±0.081 and 0.645±0.087 for Cox proportional hazards model respectively ( z values: -3.00, -2.98, -1.09, P values: 0.011, 0.018, 0.310). The ResNet showed best predictive effect for recurrence events within 12 months after surgery. Conclusion:The ResNet model is expected to be used in clinical practice for postoperative follow-up of patients with TLE, helping for risk stratification and individualized management of postoperative patients.

Objective:To evaluate the optimization effect of transcutaneous electrical acupoint stimulation (TEAS) combined with moderate sedation with propofol (TEAS-propofol balanced anesthesia) for gastrointestinal endoscopy.Methods:This was a single-blind randomized controlled trial. American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients, aged 18-64 yr, undergoing elective gastrointestinal endoscopy at the Endoscopic Diagnosis and Treatment Center of the Affiliated Hospital of Qingdao University from May to August 2022, were divided into 2 groups using the block random allocation method: conventional anesthesia group (group C) and TEAS-propofol balanced anesthesia group (group TPB). Patients received moderate sedation with propofol plus routine anesthesia with fentanyl 50 μg in group C. In TPB group, TEAS was performed at bilateral Neiguan, Hegu and Zusanli acupoints before surgery until the end of surgery, and patients received propofol for moderate sedation (Modified Observer′s Assessment of Alertness/Sedation scale score was 3). The efficacy and safety of anesthesia and parameters related to outcomes were observed and recorded.Results:In this study, 66 patients were recruited, with 33 in each group, the failure rate of anesthesia in both groups was 3%, and no reflux or aspiration was found. Compared with group C, no significant changes were found in the patients′ satisfaction on the same day, intraoperative pain response score, incidence of intraoperative adverse reactions (tachycardia, hypertension, bucking and body movement), awake time, consumption of propofol, rate of intraoperative awareness and rate of patients hoping to receive the same anesthesia method again postoperatively ( P>0.05), the patients′ satisfaction was significantly increased on the next day ( P<0.05), the incidence of intraoperative respiratory depression, physician satisfaction, and degree of postoperative dizziness and nausea were significantly reduced ( P<0.05), and the discharge time and time to the complete recovery of normal behavior function was significantly shortened in group TPB ( P<0.05). Conclusions:The combination of TEAS at bilateral Neiguan, Hegu and Zusanli acupoints with moderate sedation using propofol for gastrointestinal endoscopy is not only safe and effective, but also beneficial to the postoperative outcome of patients, and the effect is better than that of conventional anesthesia with propofol and fentanyl.

Objective:To evaluate the clinical efficacy of allogeneic hematopoietic stem cell transplantation（allo-HSCT）in children with severe aplastic anemia（SAA）.Methods:Twenty-seven cases with SAA who had been treated with allo-HSCT from January 2020 to December 2022 were retrospectively analyzed and reviewed.Results:（1）A total of 27 SAA patients were enrolled，including 18 males and 9 females，with a median age of 8 (2-15) years.There were 20 cases of SAA-Ⅰ type,7 cases of SAA-Ⅱ type.Based upon donor sources，three cases of matched sibling donors hematopoietic stem cell transplantation,and 24 cases of haploidentical hematopoietic stem cell transplantation were adopted.（2）Hematopoietic reconstruction was achieved in all 27 cases.The median implantation time of neutrophils and platelets was 10（9-20）days and 12（7-26）days respectively.The cumulative incidence of acute graft-versus-host disease（GVHD）was 66.67%（18/27）.The incidence of grade Ⅰ-Ⅱ was 55.56%（15/27）and that of grade Ⅲ-Ⅳ was 11.11%（3/27）.The incidence of chronic GVHD was 7.41%（2/27）.Transplant-associated thrombotic microangiopathy (TA-TMA) occurred in 7.41%（2/27）patients,cytomegalovirus viremia in 62.96%（17/27）patients,epstein-barr virus infection in 33.33%（9/27）patients,and 14.81%（4/27）patients progressed to post-transplant lymphoproliferative disorder (PTLD).（3）The median follow-up time was 12 (2-28) months.The overall survival rate was 96.29%.Twenty-six patients survived,and one patient died due to multiple complications of severe acute GVHD,TA-TMA,cytomegalovirus infection,PTLD and secondary epilepsy.Conclusion:Allo-HSCT is an effective therapy for SAA in children.The effective rate of this research is 96.29%.Acute GVHD is still the key to therapy.The incidence rate of acute GVHD is 66.67% in this study.The blood incompatibility of donor and recipient may affect the incidence of GVHD.The intensity of GVHD prevention should be reduced after HLA-matched sibling donor-hematopoietic stem cell transplantation so as to avoid the complications of virus recurrence and PTLD.

Objective:To investigate the distribution characteristics of virulence-related phenotypes/genotype, capsular serotype, drug resistance phenotypes, and sequence typing (ST) of Klebsiella pneumoniae in patients living in Zhongjiang county, improve clinical understanding, and provide evidence for the prevention and control of bacterial drug resistance and clinical rational drug use. Methods:The data of 135 strains of Klebsiella pneumoniae isolated from patients who received treatment in Zhongjiang County People's Hospital from July to December 2019 were retrospectively analyzed. Bacterial identification and drug sensitivity testing were performed using the WalkAway-40Plus automated microbiology system. Strains with a high viscosity phenotype were identified using wire drawing experiments. Hypervirulence-associated capsular serotype and virulence genes were verified by polymerase chain reaction. ST of Klebsiella pneumoniae strain was identified using multilocus sequence typing. Results:Strains with a high viscosity phenotype were identified in 50.4% of the 135 strains. 54.1%, 54.8%, and 54.1% of the strains were positive for virulence genes iucA, iroN, rmpA. The proportion of strains with capsular Serotype K1 or K2 was 11.9% and 15.6%, respectively. A total of 65 kinds of ST were identified, with ST23 and ST37 being the most common, accounting for 11.1% and 6.7%, respectively. The resistance rate of the strains to 16 kinds of antibiotics was 0.0%-25.2%, and the resistance rate to Carbapenem antibiotics, Amikacin, and Tigecycline was less than 1%. The positive rate of virulence gene of strains with a high viscosity phenotype was significantly higher than that of strains without a high viscosity phenotype ( P < 0.001), and its resistance rate to Cephalosporin was significantly lower in strains with a high viscosity phenotype than that in strains without a high viscosity phenotype ( P < 0.001). Conclusion:Klebsiella pneumoniae in Zhongjiang County is characterized by "high virulence and low drug resistance". It is necessary to continuously monitor the changes in the virulence and drug resistance of Klebsiella pneumoniae in Zhongjiang County, Sichuan Province, and be alert to the rapid dissemination of highly virulent strains.

The methods for determining the characteristic chromatogram and index components content of Xuanfu Daizhe Decoction were established to provide a scientific basis for the quality evaluation of substance benchmarks and preparations. Eighteen batches of Xuanfu Daizhe Decoction were prepared with the decoction pieces of different batches and of the same batch were prepared respectively, and the HPLC characteristic chromatograms of these samples were established. The similarities of the chromatographic fingerprints were analyzed. With liquiritin, glycyrrhizic acid, 6-gingerol, ginsenoside Rg_1, and ginsenoside Re as index components, the high performance liquid chromatography was established for content determination with no more than 70%-130% of the mass average as the limit. The results showed that there were 19 characteristic peaks corresponding to the characteristic chromatograms of 18 batches of Xuanfu Daizhe Decoction, including 8 peaks representing liquiritin, 1,5-O-dicaffeoylqunic acid, ginsenoside Rg_1, ginsenoside Re, 1-O-acetyl britannilactone, ginsenoside Rb_1, glycyrrhizic acid, and 6-gingerol, and the fingerprint similarity was greater than 0.97. The contents of liquiritin, glycyrrhizic acid, 6-gingerol, and ginsenosides Rg_1 + Re in the prepared Xuanfu Daizhe Decoction samples were 0.53%-0.86%, 0.61%-1.2%, 0.023%-0.068%, and 0.33%-0.66%, respectively. Except for several batches, most batches of Xuanfu Daizhe Decoction showed stable contents of index components, with no discrete values. The characteristic chromatograms and index components content characterized the information of Inulae Flos, Ginseng Radix et Rhizoma, Glycyrrhizae Radix et Rhizoma, and Zingiberis Rhizoma Recens in Xuanfu Daizhe Decoction. This study provides a scientific basis for the further research on the key chemical properties of substance benchmark and preparations of Xuanfu Daizhe Decoction.
