Stress urinary incontinence (SUI) and underactive bladder (UAB) are common types of lower urinary tract dysfunction in women.As the treatment mechanisms of the two conditions are contradictory, the treatment of SUI patients complicated with UAB remains a difficult clinical problem.In order to improve the treatment rate of such patients and promote research, this paper reviews the latest domestic and overseas diagnostic criteria of UAB, summarizes the treatment experience of conventional midurethral sling (tension-free vaginal tape or outside-in transobturator tape) and adjustable sling procedures (transobturator adjustable tape or Remeex system) combined with medication or intermittent catheterization, and the application prospects of cutting-edge technologies such as stem cell injection, cytokine therapy and gene therapy, so as to provide reference for clinicians and researchers.

[Objective] To explore the efficacy and safety of retrograde intrarenal surgery (RIRS) using a flexible negative pressure suction sheath in the treatment of upper urinary tract stones >2 cm in diameter, to provide reference for the diagnosis and treatment of such disease. [Methods] Clinical data of 155 patients who underwent surgery for upper urinary tract stones during Nov.2022 and Nov.2023 at the Second Affiliated Hospital of Shaanxi University of Chinese Medicine were retrospectively analyzed.The patients were divided into 3 groups: percutaneous nephrolithotripsy (PCNL) group (n=54), conventional sheath RIRS group (n=41), and flexible sheath RIRS group (n=60). The general and clinical data of the 3 groups were compared. [Results] The PCNL group had more patients with severe hydronephrosis (22.22% vs. 4.88%, 5.00%, P=0.027) and smaller IPA involving the lower calyx [(36.17±17.6)° vs. (48.57±17.56)°, (47.41±10.82)°, P=0.014] than the conventional sheath RIRS group and flexible sheath RIRS group.Three days after operation, the stone-free rate (SFR) was 90.74%, 53.66% and 78.33% in the PCNL, conventional sheath RIRS, and flexible sheath RIRS groups, respectively (P<0.05). At 1 month postoperatively, the SFR was 92.59%, 73.17%, and 81.67%, with no statistically significant difference between the PCNL and flexible sheath RIRS groups (P>0.05), but was higher than that in the conventional sheath RIRS group (P<0.05). The PCNL group had shorter operation time than the two RIRS groups [(65.22±17.67) min vs. (91.73±20.57) min, (94.38±24.75) min, P<0.001], longer postoperative hospital stay [(5.0(4.0, 7.0) d vs.3.0(2.0, 4.0) d, 3.0(2.0, 4.0) d, P<0.001], greater decrease in hemoglobin level [(18.00±5.78) g/L vs. (5.57±5.16) g/L, (7.42±5.09) g/L, P<0.001], and higher visual analogue scale (VAS) score [(4.83±1.48) min vs. (2.95±1.07) min, (3.05±1.21) min, P<0.001], while there was no difference between the two RIRS groups (P>0.05). The costs were lower in the flexible sheath RIRS group than in the conventional sheath RIRS group but higher than in the PCNL group [(23 311.19±1 341.20)yuan vs.(24 550.49±1 172.51)yuan, (15 351.97±1 101.4)yuan, P<0.001]. The overall incidence of complications was similar among the three groups, but stone street occurred only in the conventional sheath RIRS group. [Conclusion] For the treatment of patients with upper urinary tract stones >2 cm, RIRS has shorter postoperative hospital stay, lower hemoglobin decrease, and lower VAS score compared to PCNL; the early postoperative SFR of flexible sheath RIRS is superior to that of conventional sheath RIRS, and the 1-month SFR is comparable to that of PCNL, with a low incidence of stone street.

AIM: To analyze the similarities and differences of the clinical features between persistent hyperplastic primary vitreous(PHPV)and congenital fibrovascular pupillary membrane(CFPM).METHODS: Retrospectively analyze the ocular biometric parameters, clinical features and morphological changes in children with PHPV(PHPV group)and CFPM(CFPM group)who received surgery at the department of ophthalmology, Xijing Hospital from March 2006 to December 2021.RESULTS: The study included 56 cases(61 eyes)of PHPV and 24 cases(25 eyes)of CFPM. There were no differences on the gender and age of onset between PHPV and CFPM, and both of them were mainly unilaterally affected, with the ratio of 91% and 96%. Children with PHPV and cataract combined with other complications and ocular developmental abnormalities. CFPM was mainly presented different degrees of blockage and morphological abnormalities of pupillary area. In unilateral cases of PHPV and CFPM, the anterior chamber depth(ACD)of affected eyes was smaller than that of the fellow eyes, and in subgroups with age of operation ≤24mo, the axial length(AL)of affected eyes was smaller than that of the fellow eyes(P<0.05). The corneal diameter(CD)of the affected eyes in PHPV group was smaller and the intraocular pressure(IOP)was higher than those of the fellow eyes(all P<0.05); while there were no significant differences on CD and IOP between affected eyes and the fellow eyes in CFPM group(P>0.05). The ACD of affected eyes in PHPV group was significantly smaller than that of CFPM group(P<0.05). The fibrovascular membrane in PHPV group was located in the posterior part of the lens and vitreous cavity; while the fibrovascular membrane in CFPM group was located between the iris and the anterior capsule of the lens, rarely involving the lens.CONCLUSION: PHPV and CFPM had the similar clinical features, suggesting that they may belong to the different variants of persistent fetal vasculature(PFV). However, PHPV had a wider range of lesions and more complex conditions.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Objective    To evaluate the short-term therapeutic effect of extended adventitial inversion with graft eversion anastomosis technique in the root treatment of acute type A aortic dissection (ATAAD). Methods    From November 2019 to July 2020, 28 patients with ATAAD were treated by extended adventitial inversion with graft eversion anastomosis technique in the Department of Cardiovascular Surgery, Dalian Municipal Central Hospital, including 19 males and 9 females, aged 60.11±11.11 years. The intima of the ascending aorta was trimed to 5 mm above the sinotubular junction. The adventitia of the ascending aorta was longitudinally cut to the reserved intima margin along the junction of the three aortic valves. The extended adventitial inversion was sutured continuously, no coronary sinus was sutured over the aortic annulus, and the left and right coronary sinus was sutured above the coronary ostium. The anastomotic graft was everted and inserted into the aortic lumen, and the everted graft was continuously sutured at the level of sinotubular junction which was 5 mm away from the edge of graft. Results    There was no intraoperative death, intractable root hemorrhage, residual root false lumen, root dilatation, anastomotic hematoma or other complications. There was no recurrence of the pain in the back of all patients, and the results of the CT angiography were not significantly changed. In 22 patients with no regurgitation, only 1 (4.55%) patient had a mild regurgitation. In 6 patients with mild aortic regurgitation, the disappearance rate of regurgitation was 50.0% (3/6). Conclusion    The treatment of extended adventitial inversion with graft eversion anastomosis technique in the root treatment of aortic dissection eliminates the residual dissection at the root. The anastomotic hemorrhage is prevented, the root structure of aortic dissection is reconstructed and strengthened, the root function is restored, and the possible expansion of the root is prevented. The short-term results are satisfactory.

Aortic valve disease is one of the major diseases threatening human health. Transcatheter aortic valve replacement (TAVR) is a new treatment for aortic disease. Preoperative evaluation is of great significance to the successful operation and the long-term quality of life of patients. The 3D printing technology can fully simulate the cardiac anatomy of patients, create personalized molds for patients, improve surgical efficiency, reduce surgical time and surgical trauma, and thus achieve better surgical results. In this review, the relevant literatures were searched, and the evaluation effect of 3D printing technology on the operation of TAVR was reviewed, so as to provide clinical reference.

Objective    To evaluate the value of myocardial perfusion change before and after coronary artery bypass grafting (CABG) in predicting postoperative major adverse cardiovascular events (MACE). Methods    A total of 70 CABG patients who received CABG completed by the same operator from January to November 2017 were selected, including 45 males and 25 females with an average age of 64.83±9.09 years. The patients were divided into two groups according to whether the patients had MACE after 1 year of the surgery, including a non-MACE group (group A, n=60) and a MACE group (group B, n=10). The clinical data of patients were compared. Results    There were statistical difference in the myocardial contrast echocardiography (MCE) score in the group A before and after surgery (P<0.05), and there were statistically significant differences in the left ventricular size and left ventricular ejection fraction (LVEF) value before and 1 year after surgery (P<0.001), but no statistically significant difference in the size of left atrium (P=0.075). There was no significant difference in the preoperative and postoperative MCE score, and preoperative and postoperative 1-year cardiac ultrasound score in the group B (P>0.05). Conclusion    The change of myocardial perfusion after CABG surgery is associated with postoperative MACE. The evaluation of myocardial perfusion before and after CABG surgery is of great significance for the prognosis evaluation of patients.

BACKGROUND: Alcohol consumption has been observed to be a contributing factor in liver damage. However, very few studies have tried to decipher the correlation between patients with liver disease and alcohol consumption. Therefore, this study was planned to determine the prevalence of alcohol consumption among patients with liver disease, and to evaluate the risk factors, liver diseases, and chronic medical conditions associated with alcohol drinking. METHODS: A cross-sectional study was conducted among patients with liver disease in 30 provinces, autonomous regions, and municipalities across China. All participants answered the questionnaire, which led to the calculation of Alcohol Use Disorders Inventory Test (AUDIT) score for each patient. Based on this score, low-risk drinkers, hazardous drinkers, and harmful drinkers were defined as having AUDIT score of <8, between 8 and 15, and ≥16, respectively. RESULTS: A total of 1489 participants completed the questionnaire. Based on this information, 900 (60.44%) participants were classified as alcohol drinkers. Among these, 8.66% were ex-drinkers, 22.10% were low-risk drinkers, 17.13% were hazardous drinkers, and 12.56% were harmful drinkers. Further investigation of the association between alcohol consumption and other baseline characteristics of patients with liver disease revealed that usually men <40 years old, participants having higher family annual income, having college degree or higher education, living alone, having higher body mass index (BMI), current smokers, and ex-smokers had significant association with higher risk of alcohol consumption. In addition, among the 18.07% of the participants with cirrhosis, it was observed that risk of cirrhosis increased with higher alcohol consumption. Furthermore, harmful drinkers showed greater odds of hypertension and heart diseases, while hazardous drinkers and harmful drinkers, both had greater odds of hyperlipidemia. CONCLUSIONS Overall our analyses indicated that among the patients with liver disease in China, there was high rate of alcohol consumption and dependence. Alcohol consumption usually associated with men <40 years old, higher family income, education level, living alone, high BMI, and smoking. Increased alcohol consumption not only increased the risk of cirrhosis, but also enhanced the risk of hypertension, heart diseases, and hyperlipidemia.

Objective    To compare the effect of aspirin+ticagrelor and aspirin+clopidogrel on graft patency one year after coronary artery bypass grafting (CABG). Methods    A total of 67 patients who received CABG in our department from January 2014 to September 2017 were included in this study (52 males and 15 females). They were randomly divided into a group A (aspirin+clopidogrel) and a group B (aspirin+ticagrelor). There were 34 participants in the group A (28 males and 6 females) and 33 patients in the group B (24 males and 9 females). All patients were invited for clinical follow-up and 64-slice multislice computed tomography angiography (MSCTA) analysis in 1 year postoperatively. Cardiovascular events, bleeding events and other adverse events were followed up. Results    Four patients were lost to follow-up. Two patients died. A total of 61 patients (48 males and 13 females) completed coronary CTA, and 31 in the group A (25 males and 6 females) and 30 in the group B (23 males and 7 females). The total number of bridged vessels was 156 (59 internal thoracic artery bridges and 97 great saphenous vein bridges), including 79 in the group A (31 internal thoracic artery bridges and 48 great saphenous vein bridges) and 77 in the group B (28 internal thoracic artery bridges and 49 great saphenous vein bridges). Graft patency rate 1 year post CABG was 82.3% (65/79) in the group A and 92.2%(71/77) in the group B (P>0.05). Artery graft patency rate 1 year post CABG was 96.8% (30/31) in the group A and 96.4%(27/28) in the group B (P>0.05). Saphenous vein graft patency rate 1 year post CABG was 72.9% (35/48) in the group A  and 89.8% (44/49) in the group B (P<0.05). Multivariable analysis with binary logistic regression showed ticagrelor use reduced graft occlusion (OR=0.282, 95%CI 0.093 to 0.862, P<0.05). There was no significant difference in adverse events between the two groups. Conclusion    Compared with clopidogrel plus aspirin, ticagrelor added to aspirin after CABG may enhance the saphenous graft patency without the excess risk of bleeding 1 year post CABG.

Objective To investigate the influence of brain natrluretic peptide(BNP) in the prognosis of cardiac surgery.Methods Selected 115 cases of pafients with the first cardiac surgery.Their BNP concentration was measured before operation. Observed the relationship between BNP and postoperative atrial fibrillation,mechanical ventilation time,hospital stay,and the mortality of 30 d.Results Whether the patients had hypertension,diabetes,myocardial infarction history,left main stem disease and hemoglobin level or not,showed no definite relationship with BNP (P>0.05).Preoperative lower left ventricular ejection fraction (LVEF)(P=0.002) and European system for cardiac operation risk evaluation [(5±3)scores](P=0.003) were associated with higher BNP level.Postoperative mechanical ventilation time was(15.0±5.4)h,hospital stay was (32±11) d,showed a clear relationship with BNP(P= 0.035,0.001),but postoperative mediastinal infection,atrial fibrillation and mortality of 30 d had no definite relationship with BNP(P>0.05).Conclusion BNP can be used to predict the risk after cardiac surgery.
