Objective : To analyze the epidemiological characteristics of tuberculosis in Urumqi and assess the im⁃pact of the national health examination policy , as well as COVID⁃19 prevention and control measures , on tuberculo⁃sis incidence in Xinjiang. Methods: The seasonal patterns of pulmonary tuberculosis were examined using the seasonal index method and circular distribution analysis. An Interrupted Time Series (ITS , Interrupted Time Series) model was employed to investigate how the national health examination policy and COVID_19 interventions influenced trends in tuberculosis incidence in Urumqi. Results: From 2013 to 2021 , a total of 19 ,049 cases of tuberculosis were reported in Urumqi. The peak incidence day occurred on May 25th , indicating a consistently high rate throughout the year, particularly during spring and summer months. The results of the interrupted time series model indicated that the initial monthly incidence rate of pulmonary tuberculosis in Urumqi was 5. 05 per 100 ,000. From January 2013 to September 2016 , the incidence rate of pulmonary tuberculosis showed a slow upward trend , and the upward trend was significant (β1 = 0. 039 ,P < 0. 05) . After the implementation of the universal health checkup policy , the incidence rate of pulmonary tuberculosis showed a slow downward trend , and the downward trend was significant(β3 = - 0. 109 ,P < 0. 05) . After the outbreak of the COVID_19 epidemic in January 2020 , the incidence rate of pulmonary tuberculosis in Urumqi first dropped rapidly and then entered a slow upward stage , and the upward trend was significant(β5 = 0. 082 , P < 0. 05) . Conclusion It is recommended that public health authorities prioritize timely identification of potential TB patients during periods with elevated incidence rates observed in spring and summer months. While significant progress has been made through implementing national health examinations policies , attention must be directed towards understanding how ongoing epidemics affect TB patient detection. Thus , enhancing surveillance efforts and intervention strategies are essential in adapting to this new normal.

Objective:To evaluate the short-and medium-term therapeutic efficacy of shockwave balloon therapy for TASCⅡ C/D femoropopliteal artery atherosclerosis obliteration.Methods:This retrospective cohort study included 25 patients who received shockwave balloon therapy in five vascular centers from August 2022 to June 2023. All patients were diagnosed with TASC Ⅱ C/D femoropopliteal arteriosclerosis obliterans (13 cases of type C and 12 cases of type D), and underwent intravascular shock wave lithotripsy (IVL) to treat calcified lesions. The immediate effectiveness (residual stenosis<30% and no flow-limiting dissection), safety (whether there were adverse vascular events during the operation) and the rate of salvage stent implantation were recorded. The observation indexes of patients before operation, early postoperative period (immediately after operation or before discharge) and postoperative follow-up period (3, 6, 12 months after operation) were collected. The observation indexes included ankle-brachial index (ABI), Rutherford classification, and minimum lumen diameter (MLD). Repeated measures ANOVA was used to evaluate the changes of observation indexes in the early postoperative and follow-up stages compared with those before operation; Kaplan-Meier survival analysis was used to evaluate the one-stage patency rate at follow-up and the target lesion revascularization rate free from clinical drive.Results:The immediate effectiveness of surgery was 100% in all patients, with no vascular related adverse events occurred, and no remedial stent implantation was performed. The ABI, Rutherford grade and MLD of the patients in the early postoperative period and each follow-up stage were improved compared with those before operation, with statistically significant differences ( P<0.05). Kaplan-Meier survival analysis showed that the primary patency rate at 12 months after surgery was 0.78 (95% CI 0.64-0.84), and the revascularization rate of target lesions free from clinical drive was 0.87 (95% CI 0.85-0.95). Conclusion:Shockwave balloon therapy for complex calcified femoropopliteal artery lesions is safe and reliable, with satisfactory short-and medium-term efficacy.

Objective To compare the value of standard deviation(SD)method and root mean square(RMS)method for measuring signal-to-noise ratio(SNR)of MRI of American College of Radiology(ACR)phantom based on phased array coils.Methods ACR phantom was scanned with head coil(Head),abdominal coil(Anterior),dual piece flexible coil(Flex L)and abdominal coil+flexible coil(Anterior+Flex L)each for 6 times,respectively,with sequences of axial T 1W-spin echo(SE)and T2W-SE.And the scanning schemes were divided into 8 groups based on 4 types of coils and 2 sequences.SNR of 8 groups were measured with standard deviation method and root mean square method,respectively,and the differences between the above 2 methods were observed.Results For T1W-SE sequence,SNRsD of MRI based on Head,Anterior,Flex L and Anterior+Flex L was 1.25±0.07,0.56±0.02,1.15±0.10 and 1.04±0.11,respectively,while SNRRMs was 1.10±0.07,0.58±0.03,1.01±0.13 and 1.31±0.15,respectively.For T2W-SE sequence,SNRsD was 1.40±0.08,0.48±0.02,1.04±0.07 and 1.08±0.06,respectively,while SNRRMs was 1.29±0.09,0.53±0.03,0.84±0.08 and 1.35±0.12,respectively.Compared pairwise,significant difference of SNRsD was found in 9 pairs(all P＜0.05),while of SNRRMs was detected in 10 pairs(all P＜0.05).Conclusion Compared with standard deviation method,root mean square method was more suitable for measuring SNR of MRI of ACR phantom based on phased array coils.

[Objective]To study the application effect of the"Learning-Skill-Application"teaching method on enhancing the specialized abilities of resident doctors in residence training.[Methods]A total of 140 resident doctors in residence training who rotated in the Acupuncture and Tuina Department of Jiaxing Hospital of Traditional Chinese Medicine from July 2022 to December 2023 were included and divided into two groups by random number table method.The control group was taught traditionally,and the observation group was taught using the"Learning-Skill-Application"guided teaching method.After the rotation,the resident doctors in residence training were evaluated in multiple dimensions,including basic knowledge,clinical skills and clinical consultation ability(such as medical history collection and physical examination,clinical thinking of traditional Chinese and western medicine,medical records writing).The questionnaire survey was concurrently administered to assess resident doctors'satisfaction with the teaching performance of their clinical instructors.[Results]The observation group demonstrated superior performance in both theoretical basic knowledge exam scores and clinical skills operation scores compared with the control group(P<0.05).Additionally,the observation group exhibited better clinical consultation abilities(P<0.05)and reported higher satisfaction with the teaching methodology than the control group(P<0.05).[Conclusion]In the standardized training of Department of Acupuncture and Moxibustion and Department of Tuina,the"Learning-Skill-Application"guided teaching method is better than the traditional teaching method in improving the specialized ability of resident doctors in residence training,and is worth promoting.

As an independent first-level discipline,an appropriate classification of nursing science is significant.In China,each nursing degree-granting institution has developed its own secondary-level discipline directions based on its research characteristics and strengths,with varying names and research scopes.Furthermore,there is no unified global classification system.This paper,based on the characteristics of nursing as a discipline and combined with China's discipline classification principles,used literature analysis,comprehensive classification,philosophical reflection,logical reasoning,and expert consultation methods to explore the connotation of nursing,its unique research objects and scope,and to construct a secondary-level discipline classification system for nursing science that is suitable for China's national conditions.The paper also discussed the challenges faced by the nursing discipline and its future development directions,providing theoretical and practical guidance for the development of the nursing discipline.

Objective To investigate the clinical characteristics and related risk factors of severe Mycoplasmal pneumoniae pneumonia(SMPP)in children.Methods Analysis of clinical data of 240 children with Mycoplasmal pneumoniae pneumonia admitted to Guangxi Hospital Division of the First Affiliated Hospital,Sun Yat-sen University from October 2023 to March 2024.According to the severity of the disease,they were divided into SMPP group and general Mycoplasmal pneumoniae pneumonia(GMPP)group,multivariate Logistic regression analysis was used to analyze the risk factors related to the occurrence of SMPP.The receiver operating characteristic(ROC)curve was plotted to analyze the predictive value of each independent risk factor of SMPP.Results Compared the data during hospitalisation between GMPP group and SMPP group,the SMPP group had longer fever course,hospitalization time,azithromycin treatment time,and glucocorticoid use time(P＜0.05).The proportion of patients with unilateral lung lesions and large patchy shadows in SMPP group were significantly higher than those in GMPP group(P＜0.05).The levels of C-reactive protein,interleukin(IL)-6,and D-dimer in SMPP group were significantly higher than those in GMPP group,while the peripheral blood lymphocyte count was significantly lower than that in GMPP group(P＜0.05).The results of multiple Logistic regression analysis showed that the duration of fever,D-dimer,IL-6,and large patchy shadows in the lungs were independent risk factors for SMPP.The ROC curve results showed that fever duration ≥ 6.5 days,D-dimer≥0.495mg/L,IL-6≥11.05pg/ml,and large patchy shadows in the lungs had good application value in distinguishing SMPP and GMPP children.Conclusion Prolonged fever duration(≥6.5 days),significantly elevated levels of D-dimer and IL-6,and large patchy shadows in the lungs are the main clinical features of children with SMPP,which may be independent risk factors for predicting SMPP.

Objective To observe the clinical efficacy of scalp acupuncture combined with repetitive transcranial magnetic stimulation in the treatment of patients with mild to moderate vascular dementia and to explore its potential mechanism of action.Methods A total of 102 patients diagnosed with mild to moderate vascular dementia who were treated in the outpatient and inpatient departments of Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine from July 2021 to May 2023 were selected as the study subjects.The patients were randomly divided into an observation group and a control group using a random number table,with 51 patients in each group.The control group received repetitive transcranial magnetic stimulation treatment,while the observation group received scalp acupuncture therapy in addition to the treatment given to the control group.The treatment lasted for 16 weeks.After treatment,the clinical efficacy of the two groups was evaluated.Changes in the Mini-Mental State Examination(MMSE)scores,Montreal Cognitive Assessment(MoCA)scores,and traditional Chinese medicine(TCM)syndrome scores were observed before and after treatment.Additionally,serum levels of brain-derived neurotrophic factor(BDNF),vascular endothelial growth factor(VEGF),and homocysteine(Hcy)were measured.The cerebral blood flow velocities in the anterior,middle,and posterior arteries,as well as the levels of lipid peroxide(LPO),malondialdehyde(MDA),and superoxide dismutase(SOD),were compared between the two groups before and after treatment.The safety and incidence of adverse reactions in both groups were also evaluated.Results(1)After treatment,the MMSE and MoCA scores of both groups were significantly improved(P＜0.05),and the observation group showed significantly better improvement in MMSE and MoCA scores compared to the control group,with a statistically significant difference(P＜0.05).(2)After treatment,the serum levels of BDNF,VEGF,and Hcy in both groups were significantly improved(P＜0.05),and the observation group showed significantly better improvement in these levels compared to the control group,with a statistically significant difference(P＜0.05).(3)After treatment,the cerebral blood flow velocities in the posterior,middle,and anterior arteries were significantly improved in both groups(P＜0.05),and the observation group showed significantly better improvement in these velocities compared to the control group,with a statistically significant difference(P＜0.05).(4)After treatment,the levels of LPO,MDA,and SOD were significantly improved in both groups(P＜0.05),and the observation group showed significantly better improvement in these levels compared to the control group,with a statistically significant difference(P＜0.05).(5)After treatment,the TCM syndrome scores improved significantly in both groups(P＜0.05),and the observation group showed significantly better improvement in these scores compared to the control group,with a statistically significant difference(P＜0.05).(6)The total effective rate in the observation group was 88.24%(45/51),while it was 70.59%(36/51)in the control group.The efficacy of the observation group was superior to that of the control group,with a statistically significant difference(P＜0.05).(7)The incidence of adverse reactions in the observation group was 3.92%(2/51),while it was 1.96%(1/51)in the control group.There was no statistically significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion Scalp acupuncture combined with repetitive transcranial magnetic stimulation in the treatment of mild to moderate vascular dementia helps regulate cerebral hemodynamics and neurotrophic factor expression,improves cognitive function,and demonstrates significant efficacy with good safety.

Objective:To explore the changes in carcinoembryonic antigen(CEA)during the immune process of programmed death-1(PD-1)inhibitor Sintilimab in human epithelial growth factor receptor 2(HER2)negative advanced gastric cancer patients and its relationship with prognosis.Methods:HER2 negative late stage gastric cancer patients(88 cases)who were treated in North Anhui Coal Power Group General Hospital from May 2020 to April 2022 were selected as study subjects,all of whom received PD-1 inhibitor Sintilimab treatment;according to the prognosis,they were divided into death group(36 cases)and survival group(52 cases).Followed up was conducted every 6 months to collect tumor marker levels before and after treatment.Analyzed relationship between tumor markers(CEA,CA199,CA125)levels and clinical staging,lymph node metastasis and prognosis.Kaplan-Meier sur-vival curve was used to analyze survival time of patients with negative and positive tumor markers.Multivariate Cox regression model and stepwise regression analysis were used to identify risk factors affecting prognosis.Spearman was used for correlation analysis.Results:After two cycles of treatment,72 cases(81.82%)had disease control and 16 cases(18.18%)had progression.Compared with patients before treatment,positive rate of serum tumor markers in patients after treatment was significantly reduced(P<0.05).Positive rates of CEA and CA199 were significantly correlated with clinical staging(P<0.05).When predicting patient death,sensitivity of CEA level was the highest(48.57%),while CA125 had the highest specificity(95.62%)and the lowest sensitivity(25.71%).Kaplan-Meier sur-vival curve analysis showed that the survival time of patients with positive tumor markers were significantly shorter than that of negative patients(P<0.05).Clinical staging,serum CEA and CA199 levels were independent factors for predicting prognosis(P<0.05).Spear-man correlation analysis results showed that the multiple increases in CEA(r=-0.512,P=0.005)and CA199(r=-0.467,P=0.011)were negatively correlated with patient survival time.Conclusion:After treatment with PD-1 inhibitor Sintilimab,serum tumor markers levels in HER2 negative advanced gastric cancer patients have been significantly reduced on average.High serum levels of CEA,CA199 and CA125 can all predict poor prognosis,and clinical staging,serum CEA and CA199 levels are independent factors in pre-dicting prognosis.The higher the increase in CEA and CA199,the shorter the patient's survival time.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Cholangiocarcinoma (CCA) is a fatal malignancy with steadily increasing incidence and poor prognosis. Since most CCA cases are diagnosed at an advanced stage, systemic therapies, including chemotherapy, radiotherapy, targeted therapy, and immunotherapy, play a crucial role in the management of unresectable CCA. The recent advances in targeted therapies and immunotherapies brought more options in the clinical management of unresectable CCA. This review depicts the advances of targeted therapies and immunotherapies for unresectable CCA, summarizes crucial clinical trials, and describes the efficacy and safety of different drugs, which may help further develop precision and individualization in the clinical treatment of unresectable CCA.
