Objective:To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors.Methods:From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions.Results:Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects ( χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients ( χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications ( χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment ( R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not ( OR=1.83, P<0.001). Conclusions:Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.

Objective:To explore the clinical effects of anterolateral femoral or anteromedial femoral perforator flaps in repairing skin and soft tissue defects after resection of cutaneous squamous cell carcinoma (CSCC).Methods:This study was a retrospective observational study. From July 2015 to July 2022, 21 patients with CSCC were treated in the Department of Burns and Plastic Surgery of Guizhou Provincial People's Hospital, including 15 males and 6 females, aged from 27 to 74 years. The area of skin and soft tissue defects after extended resection of CSCC was 7.5 cm×4.0 cm to 23.0 cm×8.5 cm. The wounds in 18 patients were repaired with anterolateral femoral perforator flaps; variations of perforating branch of the descending branch of lateral circumflex femoral artery were observed in 3 patients during the operation, and the wounds were repaired with anteromedial femoral perforator flaps. The flap areas were 8.0 cm×5.0 cm to 25.0 cm×10.0 cm. The wounds in the donor areas were sutured directly in 19 patients, and the wounds in the donor areas were repaired with thin and medium-thickness skin grafts in the contralateral thigh in 2 patients. The postoperative survival of flaps and the occurrence of vascular crisis were observed. The length of operation and the hospitalization day were recorded. The recurrence of tumor, the appearances of the donor and recipient areas of flaps, the function of the flap donor area were followed up. At the last follow-up, the satisfaction degree of patients for the curative effects was evaluated.Results:The flaps survived in 20 patients, while the vascular crisis occurred in 1 patient within 48 hours after operation, and the flap survived after immediate emergency operation. The length of operation was 4 to 5 hours, and the hospitalization day was 15 to 38 days. The patients were followed up for 1 to 6 years after operation, there was no local tumor recurrence, the color and texture of the flaps were with no obvious differences to those of the surrounding tissue, and the elasticity and appearance were good. The skin grafts in the flap donor areas of 2 patients survived well with local pigmentation. There was only linear scar in the flap donor areas of all patients, and there were no significant effects on sensory and motor functions. At the last follow-up, fifteen patients were satisfied with the curative effect, and 6 patients were generally satisfied with the curative effect.Conclusions:For skin and soft tissue defects after CSCC resection, the anterolateral femoral perforator flaps can be used preferentially. In the case of variation of the perforating branch of descending branch of the lateral circumflex femoral artery, the anteromedial femoral perforator flap is selected. The areas of the two flaps are large and can be adjusted according to the amount of defect tissue, thus accurately and effectively repairing skin and soft tissue defects after CSCC resection. The postoperative appearance and function are good.

Purpose: The prognosis of patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT) is extremely poor, and systemic therapy is currently the mainstream treatment. This study aimed to assess the efficacy and safety of lenvatinib combined with anti–programmed cell death-1 antibodies and transcatheter arterial chemoembolization (triple therapy) in patients with HCC and PVTT. Materials and Methods: This retrospective multicenter study included patients with HCC and PVTT who received triple therapy, were aged between 18 and 75 years, classified as Child-Pugh class A or B, and had at least one measurable lesion. The overall survival (OS), progression-free survival (PFS), objective response rates, and disease control rates were analyzed to assess efficacy. Treatment-related adverse events were analyzed to assess safety profiles. Results: During a median follow-up of 11.23 months (range, 3.07 to 34.37 months), the median OS was greater than 24 months, and median PFS was 12.53 months. The 2-year OS rate was 54.9%. The objective response rate and disease control rate were 69.8% (74/106) and 84.0% (89/106), respectively; 20.8% (22/106) of the patients experienced grade 3/4 treatment-related adverse events and no treatment-related deaths occurred. The conversion rate to liver resection was 31.1% (33/106), with manageable postoperative complications. The median OS was not reached in the surgery group, but was 19.08 months in the non-surgery group. The median PFS in the surgery and non-surgery groups were 20.50 and 9.00 months, respectively. Conclusion Triple therapy showed promising survival benefits and high response rates in patients with HCC and PVTT, with manageable adverse effects.

Objective:To explore any effect of repeated application of low-frequency transcranial magnetic stimulation (rTMS) on depression and the cognition of depressed elderly persons.Methods:Eighty-six elderly persons with depression were randomly divided into an rTMS group and a control group, each of 43. In addition to anti-depressant treatment, the rTMS group was given 20 minutes of 1Hz rTMS daily applied over the right dorsolateral prefrontal cortex, five times a week for 4 weeks. The control group was given sham treatment on the same schedule. Before the experiment and after 1, 2, 3, 4, 6 and 8 weeks of the treatment, depression in both groups was evaluated using the Hamilton Depression Scale (HAMD-24). At the 4- and 8-week evaluations the Wisconsin Card Sorting Test (WCST) and the Trail Making Test Part A (TMT-A) were also administered.Results:Before the treatment there were no significant differences in the 2 groups′ average HAMD or WCST scores. At each subsequent evaluation both groups′ average HAMD score had decreased significantly. After 3 weeks the average HAMD score of the rTMS group consistently remained significantly lower than the control group′s average. At the 4- and 8-week evaluations both groups′ WCST and TMT-A scores had improved significantly compared with before the treatment, with significantly greater improvement in the rTMS group′s average WCST result, though not in their TPT-A result. There was no signi-ficant difference in the incidence of adverse reactions between the 2 groups.Conclusion:As a supplement to antidepressant treatment, right-side low-frequency rTMS can relieve depressive symptoms and improve the cognitive functioning of depressed elderly persons. It is well tolerated with few adverse reactions.

Objective:To explore the efficacy and safety of injection of botulinum toxin A (BTX-A) for female urethral pain syndrome (UPS).Methods:This study retrospectively included 8 women with UPS who were treated by injection of BTX-A in West China Hospital of Sichuan University from February 2021 to September 2021. The average age was (47.87±11.33) years old, the median disease duration was 3(1.0, 10.8) years. Before treatment, The visual analogue scale (VAS) was (5.38±1.92), the Pain, Urgency, Frequency score (PUF) was (10.75±5.12), and the female sexual function index (FSFI) was (14.53±11.63). 100U BTX-A was injected at the 3, 6, 9, and 12 o'clock positions of the urethral meatus, as well as at the mid-urethra and the left and right sides of the bladder neck, totaling 10 injections. The VAS, PUF score, FSFI score, and complications were recorded at 1, 3, and 6 months after treatment.Results:The VAS score decreased to (3.25±2.12), (2.88±2.23)and(2.88±2.23) at 1, 3, and 6 months, showing statistically significant differences compared to the pre-treatment scores ( P<0.05); post-treatment PUF score declined to (6.63±3.93), (6.25±4.03)and(5.13±3.31), respectively, with only the 6-month score showing a statistically significant difference compared to the pre-treatment score ( P=0.03). The FSFI score increased slightly to (14.68±11.56), (16.76±12.17) and (16.76±12.17)at 1, 3, and 6 months post-injection, respectively, with no statistically significant differences compared to the pre-treatment scores ( P>0.05). Only 1 patient had transient dysuria. Conclusion:BTX-A injection is a safe and effective treatment for UPS, and it can be used for UPS patients who are unresponsive to conservative therapy.

Objective:To explore the effect of the new model of "5G cloud plus medicine" network and linkage in improving the therapeutic effect for patients with severe trauma.Methods:A retrospective cohort study was conducted to analyze the clinical data of 410 patients with severe trauma admitted to Qingzhou People′s Hospital affiliated to Shandong First Medical University from November 2016 to November 2020. There were 258 males and 152 females, aged 16-80 years [(45.7±16.1)years]. The injury severity score (ISS) ranged from 17 to 55 points [(28.1±7.6)points]. A total of 210 patients with severe trauma were rescued by using the new model of "5G cloud plus medicine" network and linkage from November 1, 2018 to November 30, 2020 (observation group), and another 200 patients with severe trauma were rescued by the traditional treatment mode from November 1, 2016 to October 31, 2018 were selected as the control group. Time to start rescue (time from admission to the start of rescue), CT examination time (time from consultation to completion of CT scan), time to receive blood transfusion (time from blood transfusion request to execution), residence time in emergency room, ISS at postoperative 28 days, proportion of patients with blood transfusion, success rate of rescue and mortality rate were compared between the two groups.Results:Time to start rescue [(2.4±1.1)minutes], CT examination time [(29.1±10.3)minutes], time to receive blood transfusion [(28.1±10.2)minutes] and residence time in emergency room [(3.0±1.1)hours] in observation group were significantly shorter than those in control group [(5.5±1.2)minutes, (42.8±10.1)minutes, (48.5±13.1)minutes, (5.0±1.4)hours] (all P<0.05 or 0.01). ISS was (18.7±2.8)points in observation group, significantly lower than (22.1±3.4)points in control group ( P<0.05). Proportion of patients with blood transfusion was 49.5% (104/210) in observation group, similar with 42.5% (85/200) in control group ( P>0.05). Success rate of rescue was 99.0% (208/210) in observation group, significantly higher than 93.0% (186/200) in control group ( P<0.05). The mortality rate was 4.3% (9/200) in observation group, significantly lower than 8.5% (17/200) in control group ( P<0.05). Conclusion:For patients with severe trauma, the new model of "5G cloud plus medicine" network and linkage can effectively shorten the time to start rescue, CT examination time, time to receive blood transfusion and residence time in emergency room, improve the success rate of rescue and reduce the mortality rate, which is worthy of further promotion.

Objective:To investigate the effect of the liquid resuscitation therapy strategy using intra-abdominal pressure (IAP) and oxygenation index (PaO 2/FiO 2) as the end point in patients with severe acute pancreatitis (SAP). Methods:A retrospective study was performed, including 84 patients with SAP in emergency intensive care unit of Qingzhou Hospital Affiliated to Shandong First Medical University from January 2018 to August 2021. According to the status of fluid balance at admission, all patients were divided into the positive fluid balance group (43 cases) and the negative fluid balance group (41 cases). The clinical data including gender, age, etiology, underlying disease, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) and sequential organ failure assessment (SOFA) of all patients were collected. Fluid balance, PaO 2/FiO 2, IAP, compliance rate, new mechanical ventilation rate and overall hospital stay of 1 week after admission were recorded and compared between the two groups. Results:After 72 hours of treatment, the cumulative fluid balance was (5 219.5±1 038.4) mL in the positive fluid balance group; IAP was higher than that before treatment [mmHg (1 mmHg≈0.133 kPa): 11.9±2.0 vs. 11.7±2.1], but no significant difference was found ( P > 0.05); PaO 2/FiO 2 was significantly higher than that before treatment (mmHg: 299.8±51.4 vs. 220.5±50.4, P < 0.05). After 72 hours of treatment, the cumulative fluid balance in negative fluid balance group was (-3 542.4±1 310.6) mL; IAP was significantly lower than before treatment (mmHg: 11.4±1.8 vs. 15.2±1.9, P < 0.05); PaO 2/FiO 2 was significantly higher than that before treatment (mmHg: 309.9±50.9 vs. 215.4±49.7, P < 0.05). In the fluid resuscitation goals, after 72 hours of treatment, the compliance rate in the negative fluid balance group was significantly higher than that in the positive fluid balance group [82.93% (34/41) vs. 62.79% (27/43), P < 0.05]; 1 week after admission, the new mechanical ventilation rate in the negative fluid balance group was significantly lower than that in the positive fluid balance group [21.95% (9/41) vs. 41.86% (18/43), P < 0.05]; however, there was no significant difference in overall hospital stay between the two groups (days: 41.2±10.9 vs. 39.1±11.5, P > 0.05). After treatment, 70 patients survived and 14 patients died (including 9 cases in the positive fluid balance group and 5 cases in the negative fluid balance group). Conclusions:Using IAP and PaO 2/FiO 2 to guide liquid therapy could result in effective fluid resuscitation in SAP. The treatment strategy effectively improved prognosis of patients with SAP.

Objective:To retrospectively analyze the urodynamics quality in Southwest China, and find out the main issues of urodynamics quality in Southwest China and try to find out the improvement ways.Methods:In this study, a two-stage sampling method was used.In the first stage, 10 medical institutions in Southwest China were selected by cluster sampling from March to June, 2020.In the second stage, according to the development of UDS in Southwest China, the sample size estimation formula was adopted, and the loss of follow-up rate in reports extraction was considered, the initial sample size was 350. As the workload of UDS in the 10 medical institutions involved in the study was equivalent, 35 urodynamics traces from each medical institution were selected. The initial samples should also meet the inclusion criteria: ①patients with clear medical history and complete clinical data; ②UDS traces were clear; ③UDS system was water filled system; ④age>18, and 150 urodynamic traces were included in the final study. We evaluated the quality of enrolled urodynamics traces, and the quality evaluation standard according to the guidelines established by the International Continence Society (ICS). The evaluation conducted by two independent urologist with more than 10 years working experience. Artifacts were divided into non-technical artifacts: abnormal abdominal pressure changes, urine volume <150 ml when did the uroflow test, and technical artifacts: non-standard zero setting, fail to record all urodynamics parameters, baseline drift, catheter displacement, misjudgment of detrusor physiological contraction and detrusor overactive in voiding phase, misjudgment between detrusor overactive and bladder low compliance in filling phase.Results:non-technical artifacts: 32 cases were found abnormal abdominal pressure changes (21.3%), 21 cases (14.0%) were found when did the uroflow test the urine volume <150 ml, and technical artifacts: Non-standard zero setting in 28 cases (18.7%), fail to record all urodynamics parameters in 8 cases, baseline drift in 16 cases, catheter displacement in 9 cases and misjudgment of detrusor physiological contraction and detrusor overactive in voiding phase in 12 cases, misjudgment between detrusor overactive and bladder low compliance in filling phase in 24 cases (16.0%).Conclusions:At present, the urodynamics quality in Southwest China need to be improved. The main issues were that the operator didn’t obey the basic operation and quality control process, and the operator did not have enough basic knowledge of urodynamics. It can be improved by strictly carry out the operation standard of UDS, identifying and correcting artifacts in time, and promoting the standardized urodynamic training courses.

Objective:To investigate the safety and efficacy of sacral neuromodulation(SNM)therapy for the treatment of lower urinary tract dysfunction(LUTD)in elderly patients.Methods:Clinical data of 91 elderly patients with LUTD from multiple medical institutions who received SNM during the period from January 2012 to December 2016 were retrospectively analyzed.Patients were divided into four groups: the interstitial cystitis(IC)group(n=28), the neurogenic bladder(NB)group(n=36), the overactive bladder syndrome(OAB)group(n=13)and the idiopathic dysuria(ID)group(n=14). Different sets of evaluation parameters were used for different diseases.Patients’ baseline data and data in stage I(test phase)and stage Ⅱ(permanent SNM)were recorded, statistically analyzed and compared.Results:Ninety-one people underwent SNM treatment.Of them, 53 patients received permanent implants(stage Ⅱ), and the total conversion rate of stage I to stage Ⅱ was 58.2%(53/91). Patients receiving permanent implants(stage Ⅱ)had a preoperative period ranging from 3 months to 30 years, and were followed up for 2 to 58 months after treatment, with an average follow-up of 19.6 months.The improvement rates in stage I for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 35.4%, 31.6%, 33.7%, 32.6%, 49.2%, 43.2% and 13.2%, respectively.The improvement rates in stage Ⅱ for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 43.2%, 40.0%, 37.8%, 50.5%, 70.5%, 70.4% and 43.2%, respectively.Three adverse events occurred, including 1 case of recurrent symptoms, 1 case of moderate infection, and 1 case of electrical lead dislocation.Conclusions:Sacral nerve stimulation has definitive and consistent curative effects on LUTD in elderly people.The follow-up time should be extended to further study the safety of sacral nerve stimulation.
