Objective To compare the surgical outcomes of the sequence of screw and rod placement for Lenke type 5C adolescent idiopathic scoliosis(AIS).Methods Lenke type 5C AIS patients who underwent posterior orthopedic fusion and fixation in our hospital from Jan.2013 to Dec.2020 were recruited.Based on surgical sequences,22 cases were assigned to bilateral group(after bilateral screw placement,orthopedics was performed on the convex side and then on the concave side),and 20 cases were assigned to convex group(screws placed on the convex side and performed orthopedics,followed by the concave side).The operation-related indicators(including operation time),imaging parameters,quality of life scores were compared between the 2 groups before and 2 years after surgery.Complications of the 2 groups were analyzed.Results The operation time in the bilateral group was significantly longer than that in the convex group([232.8±13.1]min vs[198.4±16.5]min,P＜0.01).At the last follow-up 2 years after operation,the Cobb angle and its correction rate in the convex group were better than those in the bilateral group([8.0±2.3]° vs[9.9±3.2]°,P=0.03;[81.9±5.4]%vs[77.8±5.8]%,P=0.02).The rate of pedicle screw breach rate was 5.4%(17/312)in the bilateral group and 1.4%(4/280)in the convex group,with significant difference(P＜0.01).At the last follow-up 2 years after operation,the treatment satisfaction of quality of life assessment of the bilateral group was 4.61±1.38,and that of the convex group was 4.50±1.44,but there was no significant difference between the 2 groups(P＞0.05).There were no abnormal electrophysiological monitoring or operation-related complications in the 2 groups.Conclusion For Lenke type 5C AIS,the convex side of pedicle screw placement and orthopedics followed by concave side of pedicle screw placement and orthopedics can achieve better surgical effect.

Objective:To investigate the current situation of knowledge, attitude and practice of medical personnel in areas with high incidence of fever with thrombocytopenia syndrome (SFTS) in Anhui Province, in order to provide a scientific basis for conducting systematic training for medical personnel.Methods:From July to August 2024, a multi-stage random sampling method was used to select medical personnel from village, township, county, and city level medical institutions in high incidence areas of SFTS in Anhui Province (Hefei City, Liu'an City, Chuzhou City, Xuancheng City) for an online questionnaire survey on their knowledge, attitude, and practice status. The survey included demographic data, knowledge, attitude, and practice related to SFTS, and a binary logistic regression model was used to analyze the influencing factors of SFTS knowledge qualification rate.Results:A total of 2 718 valid questionnaires were collected, with an effective response rate of 99.60% (2 718/2 729). Among them, 1 384 were males, accounting for 50.92%. The majority were medical personnel aged 41 to 50 years old, with undergraduate degrees, junior professional titles, working in township health centers or community health service centers, as clinical physicians, and with a working experience of no more than 10 years. They accounted for 31.97% (869/2 718), 50.48% (1 372/2 718), 35.54% (966/2 718), 38.52% (1 047/2 718), 62.33% (1 694/2 718), and 30.61% (832/2 718), respectively. The overall correct rates of medical personnel's relevant knowledge, attitude and practice were 77.52% (31 605/40 770), 94.53% (12 847/13 590) and 89.73% (12 194/13 590), respectively. There were statistically significant differences in the knowledge qualification of medical personnel of different genders, ages, education levels, professional titles, hospital levels, job positions, and years of work experience ( P < 0.05). The results of binary logistic regression analysis showed that professional title, hospital level, work position, and work experience were the influencing factors of knowledge qualification rate ( P < 0.05). Conclusions:Medical personnel have a relatively positive attitude and high level of practice towards SFTS, but their knowledge level still needs to be improved. It is recommended to provide targeted knowledge training for medical personnel in different positions to promote early detection, diagnosis, and treatment of SFTS.

Linzhou,formerly known as Lin County,is the pioneer site for cancer prevention and control in China,established as early as 1959.For more than 60 years,the construction of cancer prevention and control system in Linzhou has been continuously improved,but in the face of the new situation of cancer prevention and control,the existing system has deficiencies in cancer registration,screening,treatment,scientific research,science popularization and other aspects.With the establishment of Linzhou Cancer Center,it has brought new opportunities and new mis-sions for Linzhou cancer prevention and control.Based on this,this paper puts forward a series of measures for the construction of Linzhou cancer prevention and control system,aiming to improve the Linzhou cancer prevention and control system and improve the prevention and control efficiency.

The prevention and treatment of esophageal cancer constitute an important component of China's cancer control efforts.As the earliest established cancer prevention and control field site in China,the Linzhou Esophageal Cancer Prevention and Treatment Site has developed a sys-tematic prevention and control strategy encompassing tumor registration,etiological research,early diagnosis and treatment,and other key areas,providing valuable experience for refining China's cancer prevention system.Based on over six decades of practical experience at the Linzhou site,this paper reviews its historical development,the construction of its prevention-control system,and emerging challenges in the new era,while exploring its reference significance for China's na-tionwide cancer prevention and control initiatives.

[Purpose]To analyze the trends in incidence,mortality and potential life loss of esophageal cancer in Linzhou City of Henan Province from 2010 to 2019.[Methods]The data of esophageal cancer incidence and mortality from 2010 to 2019 were collected from Linzhou cancer registries.The crude incidence and mortality rates,age-standardized rates(ASR)by sex and age group,the potential years of life lost(PYLL),average potential years of life lost(APYLL),and potential years of life lost rate(PYLLR)were calculated.The average annual percentage change(AAPC)from 2010 to 2019 were analyzed with Joinpoint software.[Results]From 2010 to 2019,there were a total of 8 447 newly diagnosed cases and 6 475 deaths of esophageal cancer in Linzhou.The ASR incidence and ASR mortality of esophageal cancer in the total population,males,females all showed significant downward trends,with AAPCs of-3.97％,-4.35％,-3.29％and-3.78％,-2.68％,-4.95％,respectively(all P＜0.05).The crude incidence and mortality rates in all age groups also showed significant downward trends.The AAPCs of incidence rate for the age groups of 0～49,50～59,60～69,and ≥70 years old were-9.92％,-8.27％,-1.41％,and-3.86％,respectively(all P＜0.05),and the AAPCs of mortality rate were-950％,-12.36％,-2.61％,and-2.98％,respectively(all P＜0.05).From 2010 to 2019,the total PYLL caused by esophageal cancer was 60 880 person years,APYLL was 13.73 person years,and PYLLR was 5.77‰.The PYLL,APYLL,and the PYLLR of the total population and those stratified by sex all showed a decreasing trend(all P＜0.05).[Con-clusion]From 2010 to 2019,the incidence,mortality and potential life loss of esophageal cancer in Linzhou City all decreased,and the long-term effect and screening programs is significant.How-ever,the risk of esophageal cancer among men and the elderly is still relatively high,indicating that more targeted prevention and control strategies should be developed.

[Purpose]To analyze the trends of incidence and mortality of malignant tumors in Linzhou City of Henan Province from 2010 to 2019.[Methods]The incidence and mortality data of malignant tumors of Linzhou cancer registration areas from 2010 to 2019 were collected and evaluated for data quality.The crude incidence/mortality rates and age-standardized incidence/mortality rates by Chinese standard population(ASIRC/ASMRC)were calculated by sex,age and can-cer type.Joinpoint software was used to calculate the average annual percentage change(AAPC)to analyze the trends from 2010 to 2019.[Results]From 2010 to 2019,the crude incidence of malig-nant tumors in Linzhou City showed an upward trend,with an AAPC of 2.09％(95％CI:0.58％～3.63％),while the ASIRC tended to be stable.The incidence of malignant tumors showed a signifi-cant upward trend in the 15～29 and 60～69 age groups,and a significant downward trend in the 70～79 age group.From 2010 to 2019,the ASIRC of esophageal cancer and stomach cancer in both men and women showed a significant downward trend,while that of lung cancer and prostate cancer increased in men,and the incidences of thyroid cancer,uterus cancer,cervical cancer,lung cancer and breast cancer increased significantly in women.From 2010 to 2019,the crude mortality of malignant tumors in Linzhou showed a significant upward trend,with an AAPC of 1.18％(95％CI:0.88％～1.48％),while ASMRC showed a significant downward trend,with an AAPC of-1.63％(95％CI:-1.86％～-1.40％).The mortality increased in the group aged 80 and above,while the other age groups remained in a downward or stable state.From 2010 to 2019,the ASMRC of stomach cancer and esophageal cancer in both men and women showed a down-ward trend,while those of prostate cancer,and malignant tumors of the lip,oral cavity and pha-ryngeal in men increased,and that of ovarian cancer in women increased significantly.[Conclu-sion]The disease burden of malignant tumors in Linzhou City is still heavy.The incidence of common cancer types such as thyroid cancer,prostate cancer and lung cancer shows a significant-ly increasing trends from 2010 to 2019.

Objectives:To investigate the clinical efficacy of bilateral mini-open Wiltse approach transforami-nal lumbar interbody fusion(MO-TLIF)in the treatment of degenerative lumbar diseases in the elderly.Meth-ods:A retrospective analysis was conducted on 62 elderly patients with single-segment degenerative lumbar diseases who underwent MO-TLIF or minimally invasive transforaminal lumbar interbody fusion(MIS-TLIF)inthe First Affiliated Hospital of Naval Medical University between September 2017 and August 2020.Among them,37 were male and 25 were female,aged 68.0±5.5 years.The patients were divided into the MO-TLIF group(32 cases)and the MIS-TLIF group(30 cases).There were no statistically significant differences between the two groups in terms of gender ratio,age,body mass index(BMI),surgical segment,disease duration,or follow-up time(P＞0.05).The differences between the two groups were compared in terms of operative time,in-traoperative blood loss,intraoperative fluoroscopy,postoperative wound drainage,time to ambulation,hospital stay,complications,and fusion rate.The visual analogue scale(VAS),lumbar Japanese Orthopedic Association(JOA)scores,and Oswestry disability index(ODI)before surgery,at 3 months postoperatively,and at the final follow-up were recorded and compared.Results:The two groups of patients all successfully completed the surgery without significant surgery-related complications.There were no statistically significant differences be-tween the MO-TLIF and MIS-TLIF groups in terms of intraoperative blood loss(80.3±25.1mL vs.72.3±21.8mL),postoperative wound drainage volume(30.7±10.2mL vs.29.3±9.0mL),or hospital stay(5.4±0.9d vs.5.4±0.8d)(P＞0.05).Compared with the MIS-TLIF group,the MO-TLIF group had shorter operative time(90.8±8.8min vs.98.3±8.0min,P=0.001)and fewer number of intraoperative fluoroscopy(4.7±0.7 times vs.7.2±1.4 times,P＜0.001).Both groups showed significant improvement in low back pain VAS score,lumbar JOA score,and ODI at postoperative 3 months and final follow-up compared with preoperative values(P＜0.001),but there were no statistically significant differences between the two groups at the same time points(P＞0.05).At the fi-nal follow-up,no internal fixation-related complications such as screw or rod breakage were observed in both groups,and all the cases achieved bone fusion.Conclusions:Bilateral MO-TLIF can achieve good therapeutic outcomes in treating single-segment degenerative lumbar diseases,which can reduce intraoperative fluoroscopy frequency and shorten operative time comparing with MIS-TLIF.
