Objective To obtain the data of radiological diagnosis and treatment resource distribution at medical institutions of different levels and in various cities, understand the status of resource allocation, provide policy-making basis and suggestions for optimizing the allocation of radiological diagnosis and treatment resources within the province, and offer data and references for related research. Methods A basic situation questionnaire survey was conducted on radiological diagnosis and treatment institutions in Hunan Province. Data were reviewed, analyzed, and statistically processed using Excel software to understand the allocation situation of radiological diagnosis and treatment resources in Hunan Province. Results As of 2022, there were 3031 radiological diagnosis and treatment institutions, 19770 radiation workers, and 6617 pieces of radiological diagnostic and treatment equipment. There were 80 radiation treatment institutions, 49 nuclear medicine institutions, 178 interventional radiology institutions, and 3028 X-ray imaging diagnosis institutions. There were 1077 radiation workers in radiation treatment, 461 radiation workers in nuclear medicine, 3369 radiation workers in interventional radiology, and 14,863 radiation workers in X-ray imaging diagnosis. There were 135 pieces of radiation treatment equipment, 56 pieces of nuclear medicine equipment, 262 pieces of interventional radiology equipment, and 6164 pieces of X-ray imaging diagnosis equipment. Conclusion Primary and lower grade medical institutions in Hunan Province account for a relatively high proportion of the total number of medical institutions, whereas radiological diagnostic and treatment resources are predominantly concentrated in tertiary medical institutions, demonstrating a unbalanced allocation of radiological diagnosis and treatment resources in various cities. In terms of the overall allocation of radiological diagnosis and treatment resources, interventional radiology is superior to the national average, nuclear medicine and X-ray imaging diagnosis are comparable to the national averages, and radiation treatment is lower than the national average. The total GDP is not the decisive factor in determining the development of local medical levels. It is suggested that relevant authorities should improve the rationality of the planning for the allocation of radiological diagnosis and treatment resources, promote the allocation of radiological diagnosis and treatment resources to the grassroots and underdeveloped areas through various measures, and thus achieve the goal of balanced resource allocation.

Objective To observe the clinical efficacy of thumb-tack needling therapy combined with Oxycodone Hydrochloride Sustained-Release Tablets in treating patients with severe cancer pain caused by malignant tumors.Methods A total of 60 patients diagnosed with severe cancer pain who were admitted to the Traditional Chinese Medicine Department of Qingpu Branch,Zhongshan Hospital Affiliated to Fudan University between November 2023 and December 2024 were selected as study subjects.Patients were randomly divided into an observation group and a control group using a random number table,with 30 cases in each group.The control group received conventional western medicine pain management,while the observation group received additional thumb-tack needling therapy based on the control group's treatment.The treatment duration was 2 weeks.After treatment,clinical efficacy was evaluated by observing changes in European Quality of Life-5 Dimensions(EQ-5D)scores,Numerical Rating Scale(NRS)scores,Cancer Pain Self-Efficacy Scale(CPSS)scores,and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire(EORTC QLQ-C30)scores in both groups before and after treatment.Changes in serum levels of prostaglandin E2,endothelin-1,β-endorphin,and substance P were also compared.Safety and adverse reactions were assessed.Results(1)The total analgesic effective rate was 76.67％(23/30)in the observation group and 46.67％(14/30)in the control group.The total effective rate in the observation group was significantly higher than that in the control group,with a statistically significant difference(P＜0.05).(2)After treatment,serum levels of prostaglandin E2,endothelin-1,β-endorphin,and substance P were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(3)After treatment,EQ-5D scores,NRS scores,and CPSS scores were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(4)After treatment,EORTC QLQ-C30 scores were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(5)The incidence of adverse reactions was 53.33％(16/30)in the observation group and 83.33％(25/30)in the control group.The incidence of adverse reactions in the observation group was significantly lower than that in the control group,with a statistically significant difference(P＜0.05).Conclusion Thumb-tack needling therapy combined with Oxycodone Hydrochloride Sustained-Release Tablets significantly alleviates pain symptoms,improves health status and self-efficacy,and enhances the quality of life in patients with severe cancer pain caused by malignant tumors.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

There are few reports in China on the laparoscopic Burch procedure in the treatment of female stress urinary incontinence. Twenty-two female stress urinary incontinence patients admitted to our hospital were treated with laparoscopic Burch procedure, with an overall effective rate of 100%. The score of the International Continence Advisory Committee Urinary Incontinence Questionnaire-Short Form (ICI-Q-SF) at one month after treatment was lower compared to that before the procedure. There were no complications during two months of follow-up.

Objective:To investigate the effects and molecular mechanism of non-coding RNA-activated DNA damage(NORAD)induced autophagy on oxaliplatin resistance in adenocarcinoma of esophagogastric junction (AEG).Methods:Four pairs of surgical samples of AEG and para-carcinoma normal tissues from patients with advance AEG treated in Anyang Tumor Hospital from January to June 2023 were collected. The expression of NORAD in AEG and para-carcinoma tissues was analyzed by long non-coding RNA microarray chip. The primary tumor cell line of AEG (PDC) was derived from fresh AEG tissues. Oxaliplatin-resistant cell lines of PDC and AEG cell line OE19 (PDC-R and OE19-R) were established. NORAD expression knockdown PDC-R and OE19 cell lines (shNORAD PDC-R and shNORAD OE19-R) were prepared by transfection. The target of NORAD, the correlation and interaction between microRNA-433-3p (miR-433-3p) and NORAD were predicted using Starbase v3.0 and DIANA-lncBase v3.0. PDC, PDC-R, OE19 and OE19-R cells were co-transfected with miR-144-3p and wild-type NORAD (NORAD-WT) or mutant NORAD (NORAD-Mut) plasmid, respectively. Dual-luciferase reporter assay was used to verify the correlation between NORAD and miR-433-3p. The expression levels of NORAD and miR-433-3p in normal gastric mucosal cell line GES-1 and AEG cell lines PDC, PDC-R, shNORAD PDC-R, OE19, OE19-R and shNORAD OE19-R were detected by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). The expression of p62 protein and microtubule-associated protein 1 light chain 3B-Ⅱ (LC3B-Ⅱ) was determined by Western blotting. The half inhibitory concentration (IC 50) of PDC, PDC-R, shNORAD PDC-R, OE19, OE19-R and shNORAD OE19-R cells was measured by cell counting kit-8 (CCK-8) assay. Independent sample t-test was used for statistical analysis. Results:The results of microarray analysis showed that NORAD was significantly up-regulated in AEG compared with that in para-carcinoma tissues (fold change≥2.0, P<0.05). Bioinformatics studies found that miR-433-3p was the potential target of NORAD. The results of dual-luciferase reporter assay indicated that the relative luciferase activity of the NORAD-WT group was lower than that of NORAD-Mut group in PDC and PDC-R cells (0.441±0.104 vs. 0.928±0.204, 0.449±0.112 vs. 0.947±0.201), and the differences were statistically significant ( t=-14.74 and -14.94, both P<0.001). The results of dual-luciferase reporter assay of OE19 and OE19-R cell lines were the same as those of PDC cell lines. The results of qRT-PCR showed that the expression of NORAD in GES-1 cells (1.016±0.213) was lower than that of PDC cells (2.194±0.322) and PDC-R cells (4.040±0.336), and the differences were statistically significant ( t=-14.94 and -37.21, both P<0.001). Furthermore, the expression level of NORAD in PDC was also found to be lower than that in PDC-R cells, and the difference was statistically significant ( t=-19.43, P<0.001). Additionally, shNORAD PDC-R cells exhibited lower expression level of NORAD (0.290±0.165) compared with PDC-R cells, and the difference was statistically significant ( t=-49.05, P<0.001). The expression level of miR-433-3p in GES-1 cells (1.017±0.248) was higher than that in PDC cells (0.470±0.156) and PDC-R cells (0.203±0.045), and the differences were statistically significant ( t=9.15 and 15.85, both P<0.001). Moreover, the expression level of miR-433-3p was found to be higher in PDC cells compared with PDC-R cells, and the difference was statistically significant ( t=8.11, P<0.001). Additionally, the expression level of miR-433-3p in shNORAD PDC-R cells (0.699±0.256) was also higher than that in PDC-R cells ( t=9.37, P<0.001). The results of Western blotting showed that the expression of LC3B-Ⅱ in PDC-R was higher than that in PDC cells (0.426±0.060 vs. 0.212±0.041), the expression of LC3B-Ⅱ in shNORAD PDC-R cells (0.155±0.029) was lower than that in PDC cells, and the differences were statistically significant ( t=8.70 and -79.45, both P<0.001). However the expression of p62 protein in each cell line showed an opposite trend, with a lower relative expression in PDC-R than PDC (0.205±0.031 vs. 0.311±0.400), and the expression in shNORAD PDC-R (0.504±0.084) was higher than that in PDC, and the differences were statistically significant ( t=-31.19 and 62.80, both P<0.001). The expression patterns of NORAD, miR-433-3p, LC3B-Ⅱ and p62 proteins in OE19, OE19-R and shNORAD OE19-R cells were similar to those in PDC. The results of CCK-8 assessment of target cell viability showed that the IC 50 values of PDC, PDC-R and shNORAD PDC-R cell lines were 14.28, 22.27 and 2.51 μg/mL, respectively; and the IC 50 values of OE19, OE19-R and shNORAD PDC-R cell lines were 3.95, 8.12 and 1.89 μg/mL, respectively. Conclusions:NORAD is highly expressed in AEG tissues and cells. NORAD is overexpressed in oxaliplatin-resistant cell lines and increase the autophagy activity of cells. After NORAD is knockdown, autophagy activity is inhibited and the sensitivity of AEG cells to oxaliplatin is significantly enhanced.

Objective:To discuss the effect of simultaneous implantation of artificial cavernous body and urethral sphincter for severe erectile dysfunction and urinary incontinence after traumatic posterior urethral stricture.Methods:A retrospective analysis was performed on 3 patients with traumatic posterior urethral stricture admitted to the Southern Theater General Hospital from January 2021 to December 2022, aged 42, 32, 28 years old, all of whom suffered pelvic fracture and posterior urethral stricture after trauma. Patient 2 were missing left lower limb and patient 3 were missing right lower limb, all of whom had dysuria. Preoperative cystourethrography indicated posterior urethral stricture with a length of 2, 2, 3 cm, respectively. No erectile response and severe erectile dysfunction were reported in penile nocturnal erectile function tests. Posterior urethral stricture was cured by end-to-end anastomosis surgery. After urethral stricture was cured, the nighttime erectile function test indicated severe erectile dysfunction and diagnosed erectile dysfunction and urinary incontinence. After 3 months of continuous administration of sildenafil and/or tadalafil, the erectile dysfunction did not improve, and the score of the international erectile function test was 1, 2, 2 points. Severe erectile dysfunction. The urine could not be controlled, the number of urine pads per day was 6, 6, 8, respectively, and pelvic floor rehabilitation training was adopted for urinary incontinence. 6 months later, urodynamic examination indicated severe stress incontinence, and the urine pad test was 30g, 32g, and 82g per hour. Patients were fully informed of the surgical risks before surgery. Simultaneous implantation of artificial penile cavernous body and artificial urethral sphincter were performed after full preoperative preparation: General anesthesia, supine frog position with transverse incision in upper scrotum, the urethra was separated and the artificial urethral sphincter cuff was easily inserted into the upper scrotum. Then the left and right sides of the penis cavernous sinus were dilated and the length of the cavernous body was measured. Suitable artificial penis cavernous body was implanted, water sacs were placed in the posterior pubic space and the anterior vesical space, and the tubes were connected. The erectile switch was placed under the scrotum, and the incision was closed after repeated testing of urine control and normal erectile function.Results:Three cases were successfully completed. The simultaneous implantation time of artificial cavernous body and artificial urethral sphincter was 270, 260, 240 min, respectively. The catheter was removed 1 week after surgery, and the erection switch was trained 2 weeks after surgery, and full erection was achieved after 1 week. The urine control switch was activated 6 weeks after surgery, and urine control was normal without urine pad. Following up for 12 to 18 months, 2 cases had normal erections and urinary control, 1 case had urethral corrosion 2 months after surgery, the original artificial sphincter was removed completely and a new artificial urethral sphincter was implanted in the same period, the operation was successful, and the follow-up was 1 year, urine control and erectile function returned to normal.Conclusions:For the severe erectile dysfunction and severe urinary incontinence after traumatic posterior urethral stricture, simultaneous implantation of artificial penile cavernous body and artificial urethral sphincter could be alternative choice.

Tertiary lymphoid structures (TLSs) is important channel for tumor immune cell infiltration. The existence of tumor TLSs is not only related to the prognosis of patients, but also to the efficacy of a variety of anti-tumor therapies. To explore the function and immunomodulatory mechanism of TLSs and its potential value as a tumor prognostic biomarker in comprehensive anti-tumor therapy will provide new ideas for follow-up research.

Objective:To evaluate the clinical application of water-filling with "four-eyes" sign under the guidance of ultrasound in nasal-jejunum intubation for critical patients.Methods:This study was a randomized controlled trial. Eighty patients who needed indwelling nasobenteric tube were selected from June 2021 to April 2022 in the Department of Critical Care Medicine, Xiangya Hospital, Central South University. They were divided into control group ( n=40) and experimental group ( n=40) by systemic randomization. For the patients in the experimental group, the intubation was performed by water-filling with "four-eyes" sign under the guidance of ultrasound. For the control group, the traditional method was applicated under the guidance of ultrasound. Using abdominal X-ray as the gold standard of successful pylorus posterior catheterization, the result of catheterization, time of operation, efficiency of positioning in the two groups were analyzed and compared. Results:In the experimental group, 38 cases were successfully intubated, 2 were failed; in the control group, 27 cases were successfully intubated, 13 were failed, and all the failed cases in the control group were then successfully intubated again by using method of the experimental group. The success rate of tube placement in the experimental group was 95.0% (38/40), which was higher than 67.5% (27/40) in the control group ( χ2 = 9.93, P<0.05). The average time of operation in the experimental group was (45.2 ± 14.2) min, which was significantly lower than (70.2 ± 17.7) min in the control group, the difference was significantly different ( t=-5.51, P<0.05). The specificity, sensitivity, positive predictive value, negative predictive value and diagnostic rate of nasal-jejunum intubation positioning in the experimental group were 100.0% respectively, higher than 38.4%, 77.7%, 72.4%, 45.4%, 65.0% in the control group; the false positive rate, false negative rate in the experimental group were both 0, lower than 22.2%, 61.5% in the control group, with statistically significant differences( χ2 values were 4.69- 16.97, all P<0.05). Conclusions:Water-filling with "four-eyes" sign under the guidance of ultrasound in nasal-jejunum intubation was a new method which can shorten the operation time and increase the success rate for intubation. It has relatively high positioning accuracy and possess valuable clinical application.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

As the National Health Commission changes the management of novel corona virus infection, the situation and preventive policies for controlling the epidemic have also entered a new stage in China. Perioperative care strategies for orthopedic trauma such as designated isolation and nucleic acid test screening have also been adjusted in the new stage. Based on the perioperative work experiences in the new stage of epidemic from the frontline anti-epidemic staff of orthopedics in domestic hospitals and combined with the literature and relevant evidence-based medical data in perioperative care of orthopedic trauma patients under the current anti-epidemic policies at home and abroad, Chinese Orthopedic Association and Chinese Society of Traumatology organized relevant experts to formulate the Guideline for clinical perioperative care of orthopedic trauma patients in the new stage of novel corona virus infection ( version 2023). The guideline summarized 16 recommendations from the aspects of preoperative diagnosis and treatment, infection prevention, emergency operation and postoperative management to systematically standardize the perioperative clinical pathways, diagnosis and treatment processes of orthopedic trauma in the new stage of novel corona virus infection, so as to provide a guidance and reference for hospitals at all levels to carry out relevant work in current epidemic control policies.
