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 investigate whether silencing signal transducer and activator of transcription 6 (STAT6) with siRNA can inhibit eosinophilic inflammation of sinonasal mucosa in a mouse model of eosinophilic chronic rhinosinusitis (ECRS).Methods:The study was conducted from March to September in 2022. Forty-eight female BALB/c mice were randomly divided into four groups: the control group, the Vehicle (transfection reagent)-treated group, the Scramble siRNA (Control siRNA)-treated group, and the STAT6 siRNA-treated group, with twelve mice in each group. An ovalbumin (OVA)-staphylococcal enterotoxin B (SEB)-induced ECRS murine model was established. SiRNA prepared in Lipofectamine was locally administered to the nasal cavity. After administration, samples of the peripheral blood and sinonasal mucosa were collected. Eosinophils in peripheral blood were detected by hematology analyzer. Total and OVA-specific IgE (OVA-sIgE) in serum were detected by enzyme-linked immunosorbent assay (ELISA). Mucosal levels of cytokines and chemokines, including interleukin (IL)-5, IL-17A, interferon-γ (IFN-γ) and eotaxin-1, were also measured using ELISA. Mucosal histological changes of eosinophil infiltration were examined using hematoxylin, and eosin staining, and tissue eosinophil count was performed using a microscope under a high-power field (HPF). Tissue expression of STAT6 and phosphorylated STAT6 (p-STAT6) was detected with the western blot method. Immunofluorescence staining was used to localize the expression of p-STAT6 in sinonasal mucosa. Statistical analysis was conducted using SPSS 18.0 software.Results:Peripheral blood eosinophil count, percentage of peripheral blood eosinophil, total serum IgE level, and serum OVA-sIgE level in the STAT6 siRNA-treated group [(0.318±0.045)×10 3/μl, (3.667±0.479)%, (102.070±13.205) ng/ml, and (38.870±7.352) ng/ml] were significantly different from those of the Vehicle-treated group [(0.532±0.049)×10 3/μl, (6.710±1.061)%, (203.102±29.653) ng/ml, and (74.575±6.432) ng/ml, Z value was -2.56, -2.24, -2.40, and -2.56, respectively, all P<0.05] and Scramble siRNA-treated group [(0.493±0.036)×10 3/μl, (5.858±0.872)%, (189.964±30.042) ng/ml, and (80.935±8.358) ng/ml, Z value was -2.17, -2.08, -2.24, and -2.72, respectively, all P<0.05]. Besides, IL-5 and eotaxin-1 levels in the STAT6 siRNA-treated group [(312.279±34.281) pg/ml and (25.297±4.323) pg/ml] were significantly lower than those in the Vehicle-treated group [(689.667±31.905) pg/ml and (68.278±6.485) pg/ml, Z value was -2.73 and -2.88, respectively, both P<0.01] and Scramble siRNA-treated group [(661.783±42.094) pg/ml and (63.015±7.416) pg/ml, Z value was -2.72 and -2.81, respectively, both P<0.01]. Tissue eosinophil count in sinonasal mucosa was (29.132±4.163)/HPF in the STAT6 siRNA-treated group, and were significantly less than those in the Vehicle-treated group [(78.050±7.912)/HPF, Z=-2.88, P<0.01] and Scramble siRNA-treated group [(73.864±8.671)/HPF, Z=-2.72, P<0.01]. The expression level of STAT6 protein (0.105±0.021) was significantly decreased in the mice treated with STAT6 siRNA compared with PBS, Vehicle, and Scramble siRNA (0.232±0.037, 0.243±0.039, and 0.228±0.032, Z value was -2.25, -2.49, and -2.56, respectively, all P<0.05). Corresponding, p-STAT6 protein level (0.292±0.038) was markedly decreased by the introduction of STAT6 siRNA, the difference was statistically significant as compared with the Vehicle-and Scramble siRNA-treated groups (0.613±0.046 and 0.641±0.050, Z value was -2.81 and -2.88, respectively, both P<0.01). Immunofluorescence staining showed that p-STAT6 was mainly located in the nucleus of nasal epithelial cells and inflammatory cells. The green fluorescence of p-STAT6 expression in sinonasal mucosa in the STAT6 siRNA-treated group was weaker than that in the Vehicle-and Scramble siRNA-treated groups. Conclusion:Intranasal administration of STAT6 siRNA can significantly downregulate STAT6 expression, decrease p-STAT6 level, and prohibit the development of Th2-skewed ECRS.

OBJECTIVE: To evaluate the effectiveness of neurovascular staghorn flap for repairing defects in fingertips. METHODS: Between August 2019 and October 2021, a total of 15 fingertips defects were repaired with neurovascular staghorn flap. There were 8 males and 7 females with an average age of 44 years (range, 28-65 years). The causes of injury included 8 cases of machine crush injury, 4 cases of heavy object crush injury, and 3 cases of cutting injury. There were 1 case of thumb, 5 cases of index finger, 6 cases of middle finger, 2 cases of ring finger, and 1 case of little finger. There were 12 cases in emergency, and 3 cases with finger tip necrosis after trauma suture. Bone and tendon exposed in all cases. The range of fingertip defect was 1.2 cm×0.8 cm to 1.8 cm×1.5 cm, and the range of skin flap was 2.0 cm×1.5 cm to 2.5 cm×2.0 cm. The donor site was sutured directly. RESULTS: All flaps survived without infection or necrosis, and the incisions healed by first intention. All patients were followed up 6-12 months, with an average of 10 months. At last follow-up, the appearance of the flap was satisfactory, the wear resistance was good, the color was similar to the skin of the finger pulp, and there was no swelling; the two-point discrimination of the flap was 3-5 mm. One patient had linear scar contracture on the palmar side with slight limitation of flexion and extension, which had little effect on the function; the other patients had no obvious scar contracture, good flexion and extension of the fingers, and no dysfunction. The finger function was evaluated according to the total range of motion (TAM) system of the Hand Surgery Society of Chinese Medical Association, and excellent results were obtained in 13 cases and good results in 2 cases. CONCLUSION The neurovascular staghorn flap is a simple and reliable method to repair fingertip defect. The flap has a good fit with the wound without wasting skin. The appearance and function of the finger are satisfactory after operation.

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 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.
