OBJECTIVES:
To evaluate the feasibility and safety of bipolar-plasmakinetic transurethral enucleation and resection of the prostate (B-TUERP) in day surgery.
METHODS:
From January 2021 to August 2022, 34 patients with benign prostatic hyperplasia (BPH) underwent B-TUERP in day surgery in the First Affiliated Hospital of Anhui Medical University. Patients completed the screening and anesthesia evaluation before admission and received the standard surgery which implements "anatomical enucleation of the prostate" and "absolute bleeding control" on the same day of admission, and by the same doctor. Bladder irrigation was stopped, catheter was removed and the discharge evaluation was performed on the first day after operation. The baseline data, perioperative conditions, time of recovery, treatment outcomes, hospitalization costs, and postoperative complications were analyzed.
RESULTS:
All operations were successfully conducted. The average age of the patients was (62.2±7.8) years, average prostate volume was (50.2±29.3) mL. The average operation time was (36.5±19.1) min, the average hemoglobin and blood sodium were decreased by (16.2±7.1) g/L and (2.2±2.0) mmol/L, respectively. The average postoperative length of hospital stay, and total length of hospital stay were (17.7±2.2) and (20.8±2.1) h, respectively, and the average hospitalization cost was (13 558±2320) CNY. All patients were discharged on the day after surgery except for one patient who was transferred to a general ward. Three patients received indwelling catheterization after catheter removal. The 3-month follow-up results showed a substantial improvement in the International Prostate Symptom Score, quality of life score and maximum urinary flow rate (all P<0.01). Three patients experienced temporary urinary incontinence, 1 patient experienced urinary tract infection, 4 patients were diagnosed with urethral stricture and 2 patients experienced bladder neck contracture. No complications above Clavien grade Ⅱ occurred.
CONCLUSIONS
The preliminary results showed that B-TUERP ambulatory surgery is a safe, feasible, economical and effective treatment for appropriately selected patients with BPH.

Development of thoracolumbar vertebra (TLV) and rib primordium (RP) is a common evolutionary feature across vertebrates, although whole-organism analysis of the expression dynamics of TLV- and RP-related genes has been lacking. Here, we investigated the single-cell transcriptome landscape of thoracic vertebra (TV), lumbar vertebra (LV), and RP cells from a pig embryo at 27 days post-fertilization (dpf) and identified six cell types with distinct gene expression signatures. In-depth dissection of the gene expression dynamics and RNA velocity revealed a coupled process of osteogenesis and angiogenesis during TLV and RP development. Further analysis of cell type-specific and strand-specific expression uncovered the extremely high level of HOXA10 3'-UTR sequence specific to osteoblasts of LV cells, which may function as anti-HOXA10-antisense by counteracting the HOXA10-antisense effect to determine TLV transition. Thus, this work provides a valuable resource for understanding embryonic osteogenesis and angiogenesis underlying vertebrate TLV and RP development at the cell type-specific resolution, which serves as a comprehensive view on the transcriptional profile of animal embryo development.

Objective:To evaluate a new imaging sign, named" bilateral water sign" (BWS), which can evaluate the neurovascular compression of primary trigeminal neuralgia (TN).Methods:A prospective study was conducted on 85 primary TN patients admitted to our hospital from March 2017 to March 2019. All patients accepted magnetic resonance 3D-T2W-DRIVEN sequence examination and multiplanar reconstruction (MPR) for post-processing. The sequential nerve (low signal)-cerebrospinal fluid (high signal)-vessel (low signal)-cerebrospinal fluid (high signal)-nerve (low signal) signs on the recombination plane were named as "BWS". The sensitivity, specificity, positive predictive value and negative predictive value of BWS in evaluating the neurovascular compression were calculated respectively, by combining with intraoperative situation of microvascular decompression (MVD).Results:In 85 TN patients, 46 patients (54.12%) had BWS. The sensitivity was 57.14%, the specificity was 75.00%, the positive predictive value was 95.65% and the negative predictive value was 15.38%. There was a statistically significant difference in the degree of neurovascular compression between patients with and without BWS ( P<0.05); and degree of neurovascular compression was severer in patients with BWS. Conclusion:BWS can evaluate the relation of neurovascular compression in TN patients and suggest the degree of neurovascular compression.

Objective To explore the role of phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway in early brain injury after subarachnoid hemorrhage (SAH) and its possible mechanism in rats. Methods Ninety healthy male SD rats were randomly divided into 5 groups (n=18) according to the random number table, namely sham-operated group, SAH group, vehicle control group, SAH+PI3K/Akt pathway agonist group (group A), and SAH+PI3K/Akt pathway inhibitor group (group I, n=18). Rat SAH models of the later 4 groups were established by intravascular puncture; rats in the vehicle control group, group A, and group I were given 10μL dimethyl sulfoxide (DMSO), insulin-like growth factor (IGF-1, 1μg/10 μL), and Ly294002 (25μg/10μL) solution, respectively, before model making. After 24 h of intravascular puncture, modified Garcia nerve function scale was used to evaluate the motor function, dry-wet weight method was used to detect the water content of the brain tissues, and immunofluorescence staining was employed to observe the β-amyloid precursor protein (β-APP)/ βtubulin III positive expressions in the subcortical white matter, and Western blotting was employed to detect theβ-APP, and total (t)-and phosphorylated (p)-PI3K and Akt protein expressions in the brain tissues; one month after modeling, HE staining was used to observe the changes of cell structure after cerebral edema. Results As compared with the sham-operated group, SAH model group had significantly lower modified Garcia nerve function scale scores, significantly increased brain water content, significantly larger number ofβ-APP/βtubulin III positive cells, statistically increasedβ-APP protein expression, and significantly increased t-PI3K, and t-Akt protein expressions (P<0.05). As compared with the SAH model group, group A had significantly higher modified Garcia nerve function scale scores, significantly decreased brain water content, significantly smaller number of β-APP/ βtubulin III positive cells, statistically decreasedβ-APP protein expression, and significantly increased p-PI3K and p-Akt protein expressions (P<0.05). As compared with group A, group I had significantly lower modified Garcia nerve function scale scores, significantly increased brain water content, significantly larger number ofβ-APP/βtubulin III positive cells, statistically increasedβ-APP protein expression, and significantly decreased p-PI3K and p-Akt protein expressions (P<0.05). HE staining showed serious morphological damage. Conclusion PI3K/Akt signaling pathway plays an important role in early brain injury after SAH in rats;early stimulation of PI3K/Akt signaling pathway activation can alleviate early brain injury after SAH, and the mechanism may be related to regulation of axonal injury in white matter after SAH.
