ABSTRACT
Objective:To investigate the safety and efficacy of ultrasound-guided sclerotherapy combined with radiofrequency ablation on the complex lymphatic malformations (LM) in children.Methods:The clinical data of 21 children with complex LM treated with ultrasound-guided sclerotherapy combined with radiofrequency ablation in the First Affiliated Hospital of Zhengzhou University from June 2018 to October 2021 were retrospectively analyzed.Intraoperative and postoperative complications were recorded.Imaging examinations were performed at 1, 3, 6, 9, 12, 18, 24 months postoperatively to observe the recurrence, the volume of the lesions and their reduction rate were calculated, and the efficacy was analyzed. Friedman test was used to compare the lesion volume at different time points before and after surgery, and the reduction rate of lesion volume at 1 month postoperatively and other time points after surgery. Results:A total of 21 children were included in this study, among them, there were 12 males and 9 females, age range from 1 month to 5 years and 6 months, with a median age of 23 months.A total of 26 LM in 21 children were successfully treated, and no serious complications like organ damage occurred during and after surgery.One patient with abdominal LM had a postoperative infection, which was controlled by 3 weeks of catheter drainage.Four LM in 3 children recurred at 3 or 6 months after surgery, while all lesions were significantly narrowed down than those before surgery and they were cured after 1-3 sessions of continued sclerotherapy.There were significant differences in the lesion volumes before surgery and 1, 3, 6, 9, 12, 18 and 24 months postoperatively [222.26(159.57, 316.40) cm 3vs.43.06(22.74, 62.53) cm 3, 31.56(15.49, 45.94) cm 3, 25.21(9.63, 36.22) cm 3, 19.80(6.79, 28.81) cm 3, 12.80(3.93, 20.38) cm 3, 7.13(0, 11.34) cm 3, and 2.79(0, 4.93) cm 3; all P<0.05]. There were significant differences between the volume reduction rates at 1 month postoperatively and 3, 6, 9, 12, 18, and 24 months postoperatively [79.36(73.30, 87.81)% vs.85.40(81.09, 91.61)%, 88.85(84.70, 93.61)%, 91.67(87.87, 95.05)%, 94.15(94.47, 97.35)%, 97.11(95.02, 100.00)%, and 99.04(97.93, 100.00)%; all P<0.05]. Patients were followed up for 24 months, and all of them were cured. Conclusions:Ultrasound-guided sclerotherapy combined with radiofrequency ablation is a minimally invasive, safe and effective therapeutic strategy for children with complex LM.
ABSTRACT
ObjectiveTo investigate the willingness of middle school students to engage in medicine and its influencing factors during COVID-19 pandemic in Lanzhou， so as to provide references for the early career planning education on middle school students. MethodsConvenient sampling method was used to choose 1 795 middle school students from 5 schools in Lanzhou from July 21 to July 31， 2022 for this study where an online questionnaire survey was distributed to collect data. A self-compiled questionnaire was used to gather the general information， assess the willingness to engage in medicine and seek the underlying reasons. The psychological resilience level of students was assessed using Resilience Scale for Adolescents. Then multivariate Logistic regression analysis was conducted to screen the factors associated with the willingness of middle school students to engage in medicine. ResultsAfter the local outbreak of COVID-19 in Lanzhou， 835 （46.52%） middle school students demonstrated their willingness to engage in medicine， and the top three reasons for their willingness were being affected by medical staff during the pandemic （75.69%）， having interests in medical sciences （67.31%）， and the potential increase of attention to national medical development after the epidemic （43.23%）. Logistical regression analysis showed that female gender （OR=1.438， P<0.01）， family members engaged in the medical and health industry （OR=1.574， P<0.01） and having a high psychological resilience score （OR=1.011， P<0.01） were related to the clear willingness to engage in medicine， while studying in senior middle school （OR=0.473， P<0.01） and excessive exposure （≥50%） to negative information during the epidemic （OR=0.797， P<0.05） were related to declining willingness to engage in medicine. ConclusionAfter the COVID-19 outbreak in Lanzhou， a large proportion of local middle school students show their willingness to engage in medicine， especially among those of female gender， having family members engaged in the medical and health industry and having high level of psychological resilience. Whereas students studying in senior middle school and with excessive exposure to negative information during the outbreak indicate low willingness to engage in medicine.

ABSTRACT
Objective:To investigate the safety and efficacy of ultrasound-guided percutaneous radiofrequency ablation in the treatment of nonmetastatic pheochromocytoma.Methods:A retrospective analysis was performed on 7 patients with nonmetastatic pheochromocytoma admitted to the First Affiliated Hospital of Zhengzhou University from January 2018 to June 2020, all of whom underwent ultrasound-guided percutaneous radiofrequency ablation. The changes of postoperative blood pressure, improvement of symptoms, intraoperative and postoperative complications were observed.Plasma free methoxypinephrine (MN) and normetanephrine (NMN) levels were recorded before and 2 weeks after operation. The reduction rate of ablation lesion volume at 1, 3 and 6 months after operation was calculated.Results:Postoperative blood pressure of all 7 patients was reduced to the normal range within 3 days, and symptoms such as headache were significantly relieved immediately after operation.No serious complications occurred during or after operation. Plasma free MN and NMN levels decreased to normal levels 2 weeks after operation. The mean reduction rates of the ablation lesions at 1, 3 and 6 months after operation were (46.61±13.42)%, (67.21±10.54)% and (85.73±4.15)%, respectively. Postoperative follow-up of 12-30 months showed that the blood pressure, plasma free MN and NMN levels of the patients were all in the normal range, and no symptoms such as headache and palpitation occurred again. All the tumors were completely ablated, and no recurrence was observed.Conclusions:Ultrasound-guided percutaneous radiofrequency ablation in the treatment of nonmetastatic pheochromocytoma is minimally invasive, safe and effective, and can retain adrenal cortex function, which is worthy of clinical promotion.
ABSTRACT
Objective:To analyze the impact of rare bacteria infection on clinical outcome in patients with diabetic foot ulcer(DFU).Methods:A total of 288 cases infected with single strains bacteria were selected. Data were grouped according to the 15 bacteria infection identified. The outcomes of healing, amputation, cardio and cerebrovascular events, and death were collected, and risk factors to the outcome were analyzed.Results:The rare infected bacteria were acinetobacter baumannii, staphylococcus epidermidis, morgan morganella, staphylococcus haemolyticus, streptococcus lactis, streptococcus agalactiae, enterobacter cloacae, and serratia marcescens.There were significant differences in age, albumin, HbA 1C, body mass index, condition of foot ulcer, degree of infection, healing, and minor amputation among these groups. Severe lower extremity arterial disease and age over 70 years were the main risk factors for the healing of ulcers. Wagner grade over 3 and infected with streptococcus lactis were the main risk factors for minor amputation. Severe lower extremity arterial disease, hemoglobin(Hb)≤90 g/L, and albumin(ALB)≤30 g/L were the main risk factors for major amputation. Estimated glomerular filtration rate <60 ml·min -1·(1.73 m 2) -1 and Hb≤90 g/L were the main risk factors for heart failure. Age over 70 years and ALB≤30 g/L were the main risk factors for death(All P<0.05). Conclusion:There exist significant differences in general condition, foot ulcer, and outcome in DFU patients infected with rare bacteria strains.
ABSTRACT
Objective:To analyze the feasibility and efficacy of ultrasound-guided percutaneous biopsy and radiofrequency ablation of gallbladder polyps.Methods:From April 2019 to January 2021, 25 patients with gallbladder polyps underwent ultrasound-guided biopsy and radiofrequency ablation in the ultrasound department of the First Affiliated Hospital of Zhengzhou University were collected, the maximum diameter of the lesion was 11.00(10.00, 12.50)mm. Under general anesthesia, ultrasound-guided injection of water into the gallbladder serosa layer was performed to make the gallbladder edema thicker than or equal to 10 mm. Percutaneous biopsy and radiofrequency ablation of gallbladder polyps were performed to ablate the gallbladder mucosa layer of polyps and polyp attachment.Intraoperative contrast-enhanced ultrasound was used to evaluate the need for supplementary ablation.The operation time, intraoperative and postoperative conditions were recorded. The complete ablation rate of gallbladder polyps, the reduction rate of lesion volume after ablation, the incidence of complications and the effect of operation on gallbladder wall thickness and gallbladder contraction rate were evaluated.Results:Biopsy and radiofrequency ablation of gallbladder polyps were successfully performed in 25 patients.There were 14 cases of cholesterol polyp, 5 cases of adenoma, 5 cases of inflammatory polyp and 1 case of gallbladder adenomyosis. Twenty-nine gallbladder polyps showed changes after ablation, and the lesion volume was reduced to varying degrees. In the first, third and sixth months, the volume reduction rates of ablation focus were 70.74%(58.55%, 77.56%), 89.47%(85.04%, 96.87%) and 100%(95.68%, 100%) respectively, and the differences were statistically significant ( P<0.05). There were no significant differences in gallbladder wall thickness and gallbladder contraction rate before and 1 month after operation ( P>0.05). The operation time was 14-39(23.32±6.68)min. During the operation, 3 patients(12.0%) had a decrease in heart rate, 2 patients(8.0%) had mild abdominal pain and 1 patient(4.0%) had obvious abdominal pain, which was relieved after treatment. No bleeding, gallbladder perforation, abdominal infection and other complications occurred. All patients were followed up for 1 to 22 months, with a median of 6 (3, 7) months. No patients were lost or follow-up, polyp recurrence, or new polyps, or secondary gallstone. Conclusions:Ultrasound-guided biopsy and radiofrequency ablation of gallbladder polyps is a feasible choice for gallbladder preserving treatment of gallbladder polyps with low complication rate.
ABSTRACT
In recent years, peptide self-assembly has received much attention because of its ability to form regular and ordered structures with diverse functions. Self-assembled peptides can form aggregates with defined structures under specific conditions. They show different characteristics and advantages (e.g., good biocompatibility and high stability) compared with monomeric peptides, which form the basis for potential application in the fields of drug delivery, tissue engineering, and antiseptics. In this paper, the molecular mechanisms, types and influencing factors of forming self-assembled peptides were reviewed, followed by introducing the latest advances on fibrous peptide hydrogels and self-assembled antimicrobial peptides. Furthermore, the challenges and perspectives for peptide self-assembly technology were discussed.

Objective:To study the safety and efficacy of ultrasound-guided radiofrequency ablation in treatment of gallbladder polyps.Methods:The clinical data of 13 patients who underwent ultrasound-guided radiofrequency ablation for gallbladder polyps at the First Affiliated Hospital of Zhengzhou University from April 2019 to March 2020 were retrospectively analyzed. These were 8 males and 5 females, with ages ranging from 20 to 49 years. The incidence of adverse reactions and complications after treatment, the complete ablation rate of polyps and the absorption of postoperative lesions were studied, and the gallbladder systolic function of patients before and after treatment were compared.Results:Of 13 patients, surgery was successfully carried out and there was no serious complications of gallbladder perforation, bleeding and collateral organ injury. The median radiofrequency ablation time was 30 s, and the complete ablation rate was 100.0%(13/13). After 6 months of follow-up, the rate of reduction of lesion volume was 100.0(98.0, 100.0)% at 6 months after surgery, which was significantly higher than the rates of 46.0(40.0, 54.0)%, 72(64.0, 100.0)% and 87.0(81.0±100.0)% at 1, 2 and 3 months after surgery ( P<0.05). The gallbladder contractility rate at 3 months after operation was (78.38±10.83)% compared with that before operation (77.46±11.28)%, and there was no significant difference ( P>0.05). Conclusion:Ultrasound-guided radiofrequency ablation for gallbladder polyps was safe. It had a significant short-term efficacy for treatment of gallbladder polyps.
ABSTRACT
Objective:To investigate the clinical efficacy of ultrasound-guided percutaneous radiofrequency ablation in the treatment of ectopic pregnancy.Methods:A retrospective analysis was performed on 8 patients with ectopic pregnancy admitted to the First Affiliated Hospital of Zhengzhou University from January 2018 to January 2020, all of whom underwent ultrasound-guided percutaneous radiofrequency ablation. Contrast ultrasonography was performed immediately after the operation to observe the changes of pregnancy sac. The length of hospital stay, mass absorption time and menstrual recovery time of the patients were recorded. Postoperative complications and serum human chorionic gonadotropin (HCG) negative conversion time were observed. At 3 months after the operation, hysterosalpingography was performed 3-7 days after the menstruation to observe the patency of the fallopian tubes, all patients were followed up for 1 year to observe the postoperative intrauterine pregnancy and re-ectopic pregnancy.Results:All the 8 patients were successfully treated with radiofrequency ablation, and postoperative ultrasonography showed that the mass remained unenhanced. The length of hospital stay was (3.0±0.8)d. The packet absorption time was (32.4±14.3)d. The recovery time of menstruation was (39.6±2.7)d. There were no serious complications.Blood HCG levels decreased rapidly within a week, and all returned to normal level of non-pregnancy 2-3 weeks after the operation. Three months after the operation, the salpingogram showed that the fallopian tubes were recanalized in 3 patients. After a follow-up of 1 year, 1 patient had a natural intrauterine pregnancy, and there was no case of recurrent ectopic pregnancy.Conclusions:Ultrasound-guided percutaneous radiofrequency ablation is effective in the treatment of ectopic pregnancy with minimal trauma and rapid recovery, and can retain the reproductive ability of patients to some extent, which is worth popularizing in clinical application.

ABSTRACT
Objective:To investigate the correlation between right-to-left shunt (RLS) and infarct pattern in patients with cryptogenic stroke.Methods:Young and middle-aged patients with acute cryptogenic stroke admitted to the Department of Neurology, Xiaogan Central Hospital from May 2016 to January 2020 were enrolled retrospectively. The demographic data, vascular risk factors, baseline blood pressure, laboratory findings, stroke severity, infarct location and distribution pattern were documented. The patients were divided into RLS group and non-RLS group according to the findings of the transcranial Doppler ultrasound foaming test. They were divided into single lesion group and multiple-lesion group according to the findings of diffusion-weighted imaging. Multivariate logistic regression analysis was used to identify the correlation between RLS and infarct pattern. Results:A total of 68 patients with acute cryptogenic stroke were included, 37 of them were male (54.4%), and their age was 47.63±6.57 years (range, 31-59 years). Thirty patients (44.1%) had RLS, including 22 (73.3%) with mild shunt and 8 (26.7%) with severe shunt. The proportions of men, cortical-subcortical infarction and multiple blood supply area lesions in the RLS group were significantly higher than those in the non-RLS group, while triacylglycerol, body mass index, the proportions of patients with subcortical infarction and single lesions in the single vessel blood supply area were significantly lower than those in the non-RLS group ( P<0.05). The proportions of patients with anterior circulation+ posterior circulation infarction, cortical-subcortical infarction, and RLS in the multi-lesion group were significantly higher than those in the single-lesion group, while the proportion of patients with subcortical infarction was significantly lower than that in the single-lesion group (all P<0.05). Multivariate logistic regression analysis showed that RLS was an independent risk factor for multiple infarctions (odds ratio 6.681, 95% confidence interval 1.206-37.019; P=0.030). Conclusion:RLS is independently associated with multiple infarctions in patients with cryptogenic stroke.

ABSTRACT
Objective:To observe the morphological changes of the deep lumbar multifidus (DM) during rest and movement among persons with chronic low back pain (cLBP) using ultrasound imaging.Methods:Twenty-one cLBP patients and 30 pain-free healthy controls were studied. The resting thickness of the DM muscle was measured, and then its cross-sectional area and thickness during maximum voluntary isometric contraction (MVIC). The results were correlated with pain intensity and duration.Results:The cLBP patients showed significant reductions in the DM′s resting thickness, and in its cross-sectional area and thickness during a MVIC compared with the healthy controls. The resting thickness of the DM was positively correlated with pain duration, but not with pain intensity.Conclusions:These results suggest that cLBP patients have atrophy and less thickness change during an MVIC. This should be considered in planning clinical rehabilitation training.
ABSTRACT
Objective@#The study is to explore daily violence exposure and its association with campus bullying, to provide theoretical basis for positive development of middle school students.@*Methods@#Questionnaire survey was conducted by using Violence Exposure Scale, Normative Beliefs about Aggression Scale, Middle School Students’ Self-control Scale, and Middle School Students’ Campus Bullying Scale. During Aug. to Oct. 2019, 1 372 middle school students were selected by the convenient sampling method as subjects of study from 2 junior high schools and 3senior high schools in Xinxiang.@*Results@#The total score in daily violence exposure was (34.22±12.09). The scores of violence exposure, traditional bullying and cyberbullying in female were lower than in male(t=-2.60--6.32, P<0.05). The scores of violence exposure, traditional bullying and cyberbullying in junior high school students were higher than senior high school students(t=4.59-7.50, P<0.05). The relationship between violence exposure and normative beliefs about aggression, traditional bullying, cyberbullying were positive (r=0.20, 0.44, 0.51, P<0.01). The relationship between violence exposure and self-control was negative (r=-0.29, P<0.01) . The relationship between normative beliefs about aggression and traditional bullying, cyberbullying were positive (r=0.28, 0.22, P<0.01). The relationship between normative beliefs about aggression and self-control was negative (r=-0.38, P<0.01). Violence exposure indirectly affects traditional bullying/cyberbullying through normative beliefs about aggression. The effect of normative beliefs about aggression on the traditional bullying/cyberbullying of middle school students is reduced with the increase of self-control.@*Conclusion@#Normative beliefs about aggression plays an intermediary role in violence exposure and traditional bully/cyberbullying, and self-control regulates the relationship between them.

ABSTRACT
Objective To discuss the correlation between dynamic changes in pulmonary function and chronic cough in 5-to-14-year-old children with Mycoplasma pneumoniae pneumonia(MPP)after acute period(about 2 weeks after admission). Methods One hundred and fifty - six hospitalized children diagnosed with MPP from Lianyungang Maternal and Child Health Care Hospital Affiliated to Yangzhou University from February 2014 to May 2017 were selected. According to the results of routine ventilatory pulmonary function before discharge(10-14 days in hospital;acute phase group),there were 50 patients with normal pulmonary function and 106 patients with abnormal pulmonary function. All patients continued to take oral azithromycin for 2 to 3 courses after discharge,and the indexes of lung function were dynamically tracked in 1 month(1-month group)and 2 months(2-month group)in the group of abnormal lung function after leaving the hospital,and the incidences and causes of chronic cough were followed up. Results (1)There were 106 cases with abnormal pulmonary function in 156 cases with MPP in acute phase group,and the rate of incidence was 67. 95%. Twenty-seven(29. 35%)out of 97 children were still abnormal in pulmonary functional testing 1 month after leaving hospital( 1-month group). Among the 27 cases,about 18. 52%(5/27 cases) of them still did not return to normal 2 months after discharge( 2-month group ). There were significant differences in the occurrence of abnormal pulmonary function among 3 groups mentioned above(χ2 ＝162. 64,P<0. 001).(2)Ratios of measured values and predicted ones of forced vital capacity( FVC ),forced expiratory volume in one second (FEV1 ),peak expiratory flow(PEF)and maximum mid-expiratory flow(MMEF 25% -75%)in the lung function of 2-month group after the acute phase of MPP were significantly higher than those of 1-month group and acute phase group,and the values of 1 -month group were better than those in acute phase one,which were statistically different among 3 groups(P<0. 01).(3)The rate of occurrence of chronic cough in normal lung function group was about 18. 00%(9/50 cases),and in abnormal pulmonary function group,it was about 70. 75%(75/106 cases). There was a significant difference between them(χ2 ＝35. 96,P<0. 05). Abnormal pulmonary functions were the influencing factors of chronic cough(r＝0. 55,P<0. 01).(4)There were 5 cases with upper airway cough syndrome(UACS)and 4 cases with post-infection cough(PIC)found in the normal lung function group. By contrast,75 cases suffered from chronic cough in abnormal pulmonary functions group,of which 36 cases with cough variant asthma( CVA),24 cases with UACS,8 cases with comorbidity of CVA and UACS and 7 cases with PIC. Conclusions Abnormal lung function after acute period of MPP may last 4 to 8 weeks,or probably even longer. In normal lung function group,UACS is the most common cause,then followed by PIC. On the contrary,the main cause of chronic cough in abnormal pulmonary function group is CVA,followed by UACS. Chronic cough is related to abnormal lung function after acute phase of MPP.
ABSTRACT
From December 2016 to February 2018,5 patients with type Ⅲ or mass type cesarean scar pregnancy (CSP) were treated in Zhejiang Taizhou Hospital.The clinical features,imaging findings and disease outcome were retrospectively analyzed.There were 3 cases of type Ⅲ and 2 cases of mass type,which were diagnosed by transvaginal ultrasound.The CSPs were resected with combination of laparoscopy and hysteroscopy,the average intraoperative blood loss was 80 ml (50-100 ml) and there were not postoperative complications.The average length of hospital stay was 9.4 days (8-12 d).Postoperative serum β-hCG returned to normal in average 22 days (14-30 d),and the menstruation recovered in 22-39 days after operation.The data indicates that resection of type Ⅲ or mass type caesarean scar pregnancy with a combination of laparoscopy and hysteroscopy is an effective treatment.
