Objective:To evaluate the mid-term complication rates of the Hui-Jing one-stage procedure (lingual mucosa combined with longitudinal preputial island flap onlay urethroplasty + tubularized incised plate glansplasty)versus the classic Bracka staged surgery for children with severe hypospadias.Methods:A retrospective analysis was conducted on clinical data of 75 children with proximal hypospadias who were treated at the Seventh Medical Center of PLA General Hospital from March 2017 to June 2022. Of these patients, 31 cases (15 cases penoscrotal type and 16 cases perineal type) were underwent the Bracka two-stage surgery with a median age of 38 months (24.0, 44.5) and 44 cases underwent the Hui-Jing one-stage procedure (23 cases penoscrotal type and 21 perineal type) with a median age of 40.5 months (20.75, 90.5). The length of urethral plate defect after correction of penile curvature was (4.30±0.84)cm in the Bracka group and (4.56±0.79)cm in the Hui-Jing group, which also showed no significant difference.There was no statistically significant difference of the median age and the position of preoperative urethral opening between the two groups( P=0.47, P=0.74). The first stage of Bracka repair consists of orthoplasty and urethral bed substitution with free preputial graft. After 6 months, the urethral plate created from free graft was tabularized to form neourethra; Hui-Jing procedure group used the free lingual mucosal as urethral plate substitution, then we conducted longitudinal preputial island flap Onlay and Snodgrass phalloplasty. The incidence of postoperative urethral fistula, urethral stricture and urethral diverticulum was compared between the two groups of cases and the difference in efficacy between the two procedures was assessed. Results:Among the 75 patients included in the study, there was no statistically significant difference in age or location of urethral meatus between the Bracka and Hui-Jing groups. In Bracka group, 9 cases of urethral stricture (29.0%), 6 case of urethral fistula (19.4%), and 2 cases of urethral diverticulum (6.5%) occurred after surgery, while 12 cases of urethral fistula (27.3%) and 3 case of urethral fistula (6.8%) occurred in the Hui-Jing group. No urethral stricture occurred in Hui-Jing group. There was no statistically significant difference in overall incidence of complications between the two groups [17/31(54.8%) vs.15/44(34.1%), P=0.12]. The incidence of urethral fistula and urethral diverticulum show no significant differences between two groups(19.4% vs 27.3, P=0.61, 6.5% vs. 6.8%, P=0.13). The number of operation in Bracka group was (2.68±1.03) and the hospitalization cost was (12 984.63±3 808.15) Yuan, while the number of operation in Hui-Jing group was (1.36±0.53) and the hospitalization cost was (8 490.54±3 136.84) Yuan. Conclusions:The Hui-Jing one-stage procedure can be used for the surgical treatment of children with severe hypospadias. There is no urethral stricture happened in Hui-Jing group, while the general complication incidence and incidence of urethral fistula and diverticulum show no differences.

BACKGROUND: Corneal confocal microscopy (CCM) is a noninvasive technique to detect early nerve damage of diabetic sensorimotor polyneuropathy (DSPN). Time in range (TIR) is an emerging metric of glycemic control which was reported to be associated with diabetic complications. We sought to explore the relationship between TIR and corneal nerve parameters in asymptomatic patients with type 2 diabetes (T2DM). METHODS: In this cross-sectional study, 206 asymptomatic inpatients with T2DM were recruited. After 7 days of continuous glucose monitoring, the TIR was calculated as the percentage of time in the glucose range of 3.9 to 10.0 mmol/L. CCM was performed to determine corneal nerve fiber density, corneal nerve branch density, and corneal nerve fiber length (CNFL). Abnormal CNFL was defined as ≤15.30 mm/mm 2 . RESULTS: Abnormal CNFL was found in 30.6% (63/206) of asymptomatic subjects. Linear regression analyses revealed that TIR was positively correlated with CCM parameters both in the crude and adjusted models (all P   <  0.05). Each 10% increase in TIR was associated with a 28.2% (95% CI: 0.595-0.866, P  = 0.001) decreased risk of abnormal CNFL after adjusting for covariates. With the increase of TIR quartiles, corneal nerve fiber parameters increased significantly (all P for trend <0.01). The receiver operating characteristic curve indicated that the optimal cutoff point of TIR was 77.5% for predicting abnormal CNFL in asymptomatic patients. CONCLUSIONS There is a significant independent correlation between TIR and corneal nerve fiber loss in asymptomatic T2DM patients. TIR may be a useful surrogate marker for early diagnosis of DSPN.

Objective:In order to analyze the current research status of handover shift in nursing management, summarize, analyze and judge the existing literature, in order to provide reference for clinical nursing practice.Methods:Through literature review, it is planned to review the current situation, shortcomings and future development of nursing handover classes.Results:The handover process was generally divided into four stages, of which SBAR was the best practice tool for handing over key information. For the performance of handover shifts, NASR, PVNC-BR, HES and Handoff CEX were often used to evaluate the performance of shifts, and for the results of shifts, evaluations were mostly conducted at the levels of patient safety, process elements, and organizational management. At present, the use of electronic information systems, benign organizational culture and patient and family-centered clinical practice could effectively improve the efficiency and effectiveness of handover.Conclusions:The process and elements of the current shift mode are relatively complete, and the communication strategy is reasonable, but there are still many shortcomings and defects. This suggests that nursing managers should adopt scientific intervention methods and evaluation tools when paying attention to and reforming nursing handover in the future to continuously improve the quality of handover.

Objective:To investigate the possible mechanism of ultrasound therapy in the rat model of sepsis.Methods:Seventy-eight male Sprague-Dawley (SD) rats were randomly divided into Sham group ( n = 12), septic model group ( n = 22), ultrasound treatment group ( n = 22), methyllycaconitine citrate (MLA) combined with ultrasound treatment group ( n = 22). In the Sham group, only the abdomen was opened, the cecum was found to be free, without cecal ligation and puncture (CLP). In the septic model group, CLP was used to replicate the septic rat model. After operation, each group of rats were subcutaneously injected with preheated 37 ℃ normal saline. The rats in the ultrasound treatment group were treated with ultrasound [Philips IU22 L9-3 ultrasound instrument and 9 MHz probe were used to break the sequence in the spleen area once every 6 seconds, with 1 second for each time, the mechanical index (MI) was 0.72, and the treatment time was 10 minutes]. In the MLA combined with ultrasound treatment group, α7 nicotinic acetylcholine receptor (α7nAChR) specific blocker MLA 4 mg/kg was injected intraperitoneally 30 minutes before operation, and ultrasound treatment was performed 2 hours after operation. The levels of tumor necrosis factor-α (TNF-α) and interleukin (IL-1β, IL-6) in serum of each group were measured by enzyme-linked immunosorbent assay (ELISA) at 24 hours after operation. The 10-day survival rate of each group was recorded, and the symptoms of each group were evaluated by clinical disease score (CDS). The histopathological changes of lung and colon were observed under light microscope. Results:Compared with the Sham group, the 10-day survival rate of rats in the septic model group was decreased significantly [40% (4/10) vs. 100% (6/6)], the CDS was (10.73±2.19 vs. 6.17±0.58) and the levels of TNF-α, IL-6, and IL-1β were increased significantly at 24 hours after operation [TNF-α (ng/L): 42.00±8.92 vs. 13.16±3.19, IL-6 (ng/L): 129.37±25.04 vs. 63.99±12.92, IL-1β(ng/L): 254.98±67.27 vs. 76.83±25.39, all P < 0.01]. Compared with the septic model group, the survival rate in the ultrasound treatment group was improved [70% (7/10) vs. 40% (4/10)], but there was no significant difference ( P > 0.05). The CDS (7.64±2.68 vs. 10.73±2.19) and the expressions of TNF-α, IL-6, and IL-1β were significantly reduced at 24 hours after operation [TNF-α(ng/L): 16.93±6.02 vs. 42.00±8.92, IL-6 (ng/L): 73.65±24.38 vs. 129.37±25.04, IL-1β(ng/L): 111.86±14.08 vs. 254.98±67.27, all P < 0.01]. Compared with the ultrasound treatment group, the survival rate in the MLA combined with ultrasound treatment group was reduced [60% (6/10) vs. 70% (7/10)], but the difference was not statistically significant ( P > 0.05). CDS was significantly increased (9.55±2.72 vs. 7.64±2.68), and the levels of TNF-α, IL-6 and IL-1β were significantly increased at 24 hours after operation [TNF-α(ng/L): 34.61±7.89 vs. 16.93±6.02, IL-6 (ng/L): 112.92±10.42 vs. 73.65±24.38, IL-1β(ng/L): 212.57±32.16 vs. 111.86±14.08, all P < 0.01]. Microscopically, in the septic model group, the alveolar septum was thickened, a large number of inflammatory cells infiltrated, normal pulmonary reticular structure disappeared, and pulmonary interstitium showed obvious hemorrhage and edema, meanwhile, the structure of colonic villi was obviously abnormal, with cells were edema and inflammatory cell infiltration, and the arrangement was disordered, so that the subepithelial space and the top of it fell off. After ultrasound treatment, the thickness of the alveolar interval in rats was similar to that in Sham group, without obvious inflammatory cell infiltration, and the pulmonary reticular structure was relatively intact. At the same time, the morphology of colonic villi was basically normal and orderly, the edema of cell was not obvious, and subcutaneous space and tip fall off were not obvious. After being antagonized by MLA, the rat lung tissue showed thickened alveolar septum, inflammatory cell infiltration, incomplete pulmonary network structure, hemorrhage and edema in the interstitium. The villi structure of the colon was faintly visible, with obvious cell edema and inflammatory cell infiltration, and the arrangement was abnormal. Conclusion:Ultrasound treatment improves the prognosis of septic rats, MLA can reverse the anti-inflammatory effect of ultrasound therapy by antagonizing α7nAChR, suggesting that the protective mechanism of ultrasound in sepsis may be related to activating the cholinergic anti-inflammatory pathway mediated by α7nAChR.

Objective    To evaluate the efficiency and safety of intraprocedural valve-in-valve deployment for treatment of aortic regurgitation following transcatheter aortic valve replacement (TAVR). Methods    Consecutive patients (n=333) who diagnosed with severe aortic stenosis and underwent TAVR in Zhongshan Hospital affiliated to Fudan University from October 3rd, 2010 to April 21st, 2021 were included. There were 208 males and 125 females aged 76.0±7.0 years. There were 316 patients underwent simple TAVR (simple TAVR group) and 17 patients underwent intraprocedural valve-in-valve deployment following TAVR (valve-in-valve group). Their clinical and echocardiographic outcomes were evaluated and compared. Results    There was no significant difference between the two groups of patients at postoperative 30 d and 1 year in all-cause mortality (4.4% vs. 0, P=1.000; 6.3% vs. 0, P=1.000), incidence of pacemaker implantation (10.4% vs. 17.6%, P=1.000; 11.8% vs. 17.6%, P=1.000), incidence of ischemic stroke (1.3% vs. 0, P=1.000; 1.3%  vs. 0, P=1.000), mean trans-aortic pressure gradient (11.4±6.4 mm Hg vs. 8.9±4.9 mm Hg, P=0.099; 10.5±7.6 mm Hg vs. 11.2±5.2 mm Hg, P=0.432), left ventricular ejection fraction (62.0%±9.0% vs. 57.0%±12.0%, P=0.189; 63.0%±7.0% vs. 60.0%±8.0%, P=0.170), and incidence of mitral valve dysfunction (0.6% vs. 5.9%, P=1.000; 0.6% vs. 5.9%, P=1.000). Conclusion    It is feasible to treat perivalvular leakage with valve-in-valve technology in the procedure of TAVR, and the short and medium-term effects are satisfied.

Objective:To explore the protective effect of vagus nerve stimulation (VNS) on the prognosis of rats suffering from cardiac arrest/cardiopulmonary resuscitation (CA/CPR) under different treatment timings.Methods:The method of percutaneous epicardial electrical stimulation was used to establish CA model of rat. Fifty-three male SD rats were randomly (random number) divided into the sham group ( n=5), CPR group ( n=12), PRE group ( n=12), POST5 group ( n=12) and POST30 group ( n=12). The sham group did not experience CA/CPR. VNS treatment was started at 30 min before CA (PRE group, n=12), 5 min after recovery of spontaneous circulation (ROSC) (POST5 group, n=12), and 30 min after ROSC (POST30 group, n=12) in different VNS-treated group, respectively. The electrical stimulation was applied to the vagus nerve for 30 min with a unified parameter. The neurological deficit scores at 24, 48, and 72 h after ROSC were recorded, and the survival rate in each group was observed. TUNEL staining was used to detect the apoptosis of cortical area and the expression of α7 nicotinic acetylcholine receptor (α7nAChR) in brain tissue was measured by immunofluorescence at 72 h after ROSC. Variables were compared with one-way analysis of variance, and survival for Kaplan-Meier curves were tested with the log-rank test. A P value less than 0.05 was considered statistically significant. Results:Compared with the CPR group (survival rate 33.33%), both pre-treatment (survival rate 75%) and post-treatment of VNS (POST5 group survival rate 75% and POST30 group survival rate 83.33%) significantly improved the 72 h survival rate after CPR ( P<0.05), mitigated neurological deficits after ROSC, reduced the positive rate of apoptosis neurons, and up-regulated the expression of α7nAChR in cerebral cortex. There was no significant difference among the VNS-treated groups (all P>0.05). Conclusions:Both pre-treatment and post-treatment of VNS can play a protective role in rats after CA/CPR, which may be related to the activation of α7nAChR-mediated anti-inflammatory and anti-apoptosis effects.

Objective To understand the rationality and safety of oral antihypertensive drugs on chronic renal disease(CKD)combined with hypertension hospitalized patients. Methods It was a multi-center and retrospective investigation. The electronic medical records of CKD with hypertension patients who were hospitalized in 6 comprehensive hospitals in Beijing and used oral antihypertensive drugs on October 1st,2013 to March 31st,2015 were collected. The pharmacists who participated in the project from the 6 research centers filled out the investigation form. According to the drug instruction,the rationality of antihypertensive medication was evaluated by daily dose,frequency of drug delivery,the dosage for renal insufficiency,contraindications and adverse interactions. Results There were 2 833 valid cases in this study,1 730 males and 1 103 females. The ratio of male to female was 1:0.64. The range of age was 18~101 years. The average age was(61 ± 18)years. There were 1 630(57.54%)cases whose age was≥60;314(11.1%)cases were CKD level 1,526(18.6%)cases were CKD level 2,1 117(39.4%)cases were CKD level 3,423(14.9%)cases were CKD level 4,453(16.0%)cases were CKD level 5. 144 (5.1%)cases were hypertension level 1,592(20.9%)cases were hypertension level 2,1 398 cases (49.3%)were hypertension level 3,and 699(24.7%)cases were not graded. The oral hypotensive drugs applied during the hospitalization of 2 833 patients included calcium channel blockers(CCB),beta blockers,diuretics,angiotensin Ⅱ receptor blocker(ARB),angiotensin converting enzyme inhibitors (ACEI),alpha/beta blockers and alpha blockers. 1 022(36.1%)cases used 1 kind of antihypertensive drugs,1 032(36.4%)cases used 2 kinds of antihypertensive drugs,591(20.9%)cases used 3 kinds of antihyper-tensive drugs,157(5.5%)cases used 4 kinds of antihypertensive drugs and 31(1.1%)cases used 5 kinds of antihypertensive drugs. A total of 6038 cases of antihypertensive drugs were administered. The top priority was CCB(35.11%,2 120),the second was beta blockers(17.26%,1 042)and the third was diuretics(16.23%,980). The choice of a single drug for antihypertensive drugs was reasonable. The 2,3,4,5 combined drug users who were not recommended by the guidelines were 4.8%(50/1 032), 21.2%(125/591),28.0%(44/157)and 64.5%(20/31)respectively. The situation of blood pressure control was evaluated with blood pressure target values achieved rate. With blood pressure below 130/80 mmHg as the standard,the admission and discharge blood pressure target achieved rate was 31.2%(884/2 833)and 29.5%(799/2 705)respectively. With blood pressure below 140/90 mmHg as the standard, the admission and discharge blood pressure target achievement rate was 53.6%(1 519/2 833)and 64.4%(1 743/2 705)respectively. Among the 2 833 cases,903(31.9%)cases had 1 204 times of unreasonable use of the drug. The top three were excessive daily frequency of medication(1 029,85.5%),total daily dosage(114,9.5%),and use of drugs that were contraindicated(51,4.2%). Two cases had adverse drug reactions related to antihypertensive drugs. Conclusion The use of antihypertensive drugs in patients with CKD in the six hospitals involved in the investigation was reasonable,but there was still some problems in the combination of drugs. Some doctors are not familiar with the drug instructions,and there are some problems such as increasing the frequency of drug use,overdose medication,and use of drugs that are contraindicated. Clinical pharmacists should be more involved in clinical work in these areas.
