The clinical efficacy of single-hole punch excision combined with intralesional steroid injection for nodular keloid treatment: a self-controlled trial.

There are many methods to treat keloid, including various excision operations, laser, injection and radiotherapy. However, few studies have explored the effectiveness of single-hole punch excision in keloid treatment. This study aimed to investigate the efficacy and safety of lateral punch excision combined with intralesional steroid injection for keloid treatment through self-control trial. In this self-controlled trial, 50 patients meet the diagnosis of nodular keloid, and try to choose left-right symmetrical control, one skin lesion in the control group (50 skin lesionsin total) and the other in the observation group (50 skin lesions in total).The keloids in the treatment group were initially treated with punch excision combined with intralesional steroid injection, followed by injection treatment alone. Keloids in the control group received intralesional steroid injection alone. The Vancouver Scar Scale (VSS) of the keloid before and after the punch excision was evaluated; the keloid scores at different time points and the number of injection treatments required in both groups were compared, and adverse reactions were observed. The effective rate of the observation group was 86.0%, which was significantly higher than that of the control group (66.0%), and the recurrence rate of 22% was lower than that of the control group (χ2 = 4.141,63417), all of which were statistically significant (all P < 0.05). At the end of treatment, the VSS and total injection times in the observation group were significantly lower than those in the control group (t = 5.900,3.361), with statistical significance (P < 0.01). The combination of single-hole punch excision and intralesional steroid injection is an effective method to treat multiple nodular keloids, shortening the treatment course of tralesional steroid injection without obvious adverse reactions.

Study on Bearing Strength and Failure Modes of Single Bolted Joint Carbon/Epoxy Composite Materials.

The growth of the Urban Air Mobility (UAM) industry emphasizes the need for considerable study into assembly procedures and dependability to guarantee its effective integration into air transport networks. In this context, this study seeks to evaluate the mechanical characteristics of bolted joint Carbon Fiber Reinforced Plastic (CFRP), with a particular emphasis on bearing strength. By altering the w/D (specimen width to hole diameter) and e/D (distance between hole center and specimen end to hole diameter) ratios, the study investigates how edge and end distances affect material performance. The study discovered a shift from tension to bearing failure at w/D ratios of 4.0, with maximum bearing strength decreases of 90.50% and 69.96% compared to full bearing failure. Similarly, for e/D ratios of 1.5, 2.0, and 3.0, transitioning from shear to bearing failure at 2.0 resulted in maximum bearing strength losses of 94.90% and 75.96%, respectively. Maintaining a w/D ratio of at least 6.0 and an e/D ratio of at least 3.0 is critical for maintaining maximum performance and stability in CFRP structure design.

Comparison of efficacy of single-port versus conventional laparoscopic treatment for uterine leiomyoma: a latest meta-analysis.

Objective: Single-port laparoscopy has been proposed as an ideal surgical method for the treatment of uterine leiomyoma. It can effectively remove the lesion, reduce the loss of hemoglobin, and has superior cosmetic effects. Therefore, we searched relevant studies and conducted a meta-analysis to evaluate the effect of single-port laparoscopy on myoma resection, hemoglobin loss, and scar beauty compared to conventional laparoscopy. Methods: We systematically searched PubMed, EMBASE, scope, Cochrane, CNKI, and other databases to find randomized controlled studies on the efficacy of single-port laparoscopy and traditional laparoscopy for meta-analysis. The main outcomes of our study were the duration of surgery, the reduction of hemoglobin, and the cosmetic effect of the postoperative scar. The effect model was selected according to heterogeneity (random effect model or fixed effect model), and the relevant sensitivity analysis and publication bias test were performed. Results: We searched a total of 501 related literature articles and finally included 19 studies involving 21 researchers. Comparison of single-port laparoscopic myomectomy with traditional surgery: Operation time had no significant difference (Standardized Mean Difference [SMD]: 0.13, 95% Confidence interval (CI), -0.04 to 0.30; I²=74%; P = 0.14); The reduction of hemoglobin is lower ([SMD]: -0.04; 95% CI, -0.23 to 0.14; I²=71%; P = 0.65), and the cosmetic effect of postoperative scar is more satisfactory ([SMD]: 0.42, 95% CI: 0.02 to 0.83; I²=72%, P= 0.04). There was no significant difference in conversion rate, postoperative pain, blood loss, postoperative gastrointestinal recovery time, or length of hospital stay. Conclusion: Compared with traditional laparoscopy, the operation time of the treatment of uterine leiomyoma by single-port laparoscopy is not extended, the reduction of hemoglobin is less, and the cosmetic effect of the scar is better. Therefore, single-port laparoscopy is superior to traditional surgery in the treatment of uterine leiomyoma.

Enhanced recovery of postoperative nursing for single-port thoracoscopic surgery in lung cancer patients.

Lung cancer is a common clinical malignant tumor, and the number of new lung cancer patients is increasing year by year. With the advancement of thoracoscopy technology and equipment, the scope of application of minimally invasive surgery has expanded to almost all types of lung cancer resection, making it the mainstream lung cancer resection surgery. Single-port thoracoscopic surgery provides evident advantages in terms of postoperative incision pain since only a single incision is required, and the surgical effect is similar to those of multi-hole thoracoscopic surgery and traditional thoracotomy. Although thoracoscopic surgery can effectively remove tumors, it nevertheless induces variable degrees of stress in lung cancer patients, which eventually limit lung function recovery. Rapid rehabilitation surgery can actively improve the prognosis of patients with different types of cancer and promote early recovery. This article reviews the research progress on rapid rehabilitation nursing in single-port thoracoscopic lung cancer surgery.

Coherence Characteristics of a GaAs Single Heavy-Hole Spin Qubit Using a Modified Single-Shot Latching Readout Technique.

We present an experimental study of the coherence properties of a single heavy-hole spin qubit formed in one quantum dot of a gated GaAs/AlGaAs double quantum dot device. We use a modified spin-readout latching technique in which the second quantum dot serves both as an auxiliary element for a fast spin-dependent readout within a 200 ns time window and as a register for storing the spin-state information. To manipulate the single-spin qubit, we apply sequences of microwave bursts of various amplitudes and durations to make Rabi, Ramsey, Hahn-echo, and CPMG measurements. As a result of the qubit manipulation protocols combined with the latching spin readout, we determine and discuss the achieved qubit coherence times: T1, TRabi, T2*, and T2CPMG vs. microwave excitation amplitude, detuning, and additional relevant parameters.

Preliminary Analysis of Safety and Feasibility of a Single-Hole Laparoscopic Myomectomy via an Abdominal Scar Approach.

Purpose: This paper aims to explore the safety and feasibility of a single-hole laparoscopic myomectomy through an abdominal scar approach. Method: The clinical data of seven patients who underwent the single-hole laparoscopic myomectomy via the abdominal scar approach from January to November 2021 in the Department of Gynecology, the Affiliated Changzhou No. 2 People's Hospital of Nanjing Medical University, were studied retrospectively. The duration of operation, the intraoperative blood loss, the decrease of postoperative hemoglobin, and the postoperative visual analogue score (0 points: no pain, 10 points: maximum pain) were recorded. Results: All seven patients received the operation successfully, without changing to the conventional laparoscopic operation or open appendectomy. The average blood loss was 101.42 ± 7.89 ml, the average length of hospital stay was 5 ± 0.53 days, the average operation duration was 130 ± 26.86 min, and the 24-h pain score was 1.57 ± 0.53. The seven patients had no intraoperative or postoperative complications and no damage to the ureter or bladder. All patients could urinate spontaneously without urinary retention or urinary tract infection after catheter removal. No analgesic drugs were used after the operation. Conclusion: The single-hole laparoscopic myomectomy via the abdominal scar approach is a more aesthetic and feasible option for eligible patients, but more cases and studies are needed for further confirmation.

Surgical Management of Hirschsprung's Disease: A Comparative Study Between Conventional Laparoscopic Surgery, Transumbilical Single-Site Laparoscopic Surgery, and Robotic Surgery.

Background: Hirschsprung's disease (HD) is a commonly digestive malformation in children that usually requires surgery. This study aims to evaluate the short-term efficacy of conventional laparoscopic surgery (CLS), transumbilical single-hole laparoscopic surgery (TU-LESS), and robotic surgery (RS) in the treatment of Hirschsprung's disease. Methods: 90 patients with Hirschsprung's disease undergone laparoscopic surgery at our center between 2015 and 2019, divided into three groups (group CLS, TU-LESS and RS), were retrospectively analysed. Results: CLS and TU-LESS group showed no significant difference in operation duration (P > 0.05) but shorter operation duration than the RS group (P < 0.05). RS group had highest overall SCAR scores, while TU-LESS group had the lowest one (P < 0.05). Other parameters such as operative blood loss, hospital stays, recovery time of digestive function, postoperative complications had no significant difference among the three groups (P > 0.05). Conclusion: The three surgical methods for HD revealed similar efficacy, where TU-LESS and CLS spent less time than RS; TU-LESS led to the most aesthetic effect, followed by CLS and RS.

Probing hole spin transport of disorder quantum dots via Pauli spin-blockade in standard silicon transistors.

Single hole transport and spin detection is achievable in standard p-type silicon transistors owing to the strong orbital quantization of disorder based quantum dots. Through the use of the well acting as a pseudo-gate, we discover the formation of a double-quantum dot system exhibiting Pauli spin-blockade and investigate the magnetic field dependence of the leakage current. This enables attributes that are key to hole spin state control to be determined, where we calculate a tunnel couplingtcof 57µeV and a short spin-orbit lengthlSOof 250 nm. The demonstrated strong spin-orbit interaction at the interface when using disorder based quantum dots supports electric-field mediated control. These results provide further motivation that a readily scalable platform such as industry standard silicon technology can be used to investigate interactions which are useful for quantum information processing.

Clinical application and research progress of single-hole laparoscopy / 西安交通大学学报(医学版)

The minimally invasive surgery is the mainstream of the development of surgery, and the transformation of surgery from traditional open surgery to endoscopic surgery has brought great benefits to patients. However, surgeons have never stopped their exploration from porous laparoscopy to single hole or even endoscopic surgery via the natural cavity, and looking for a more minimally invasive way of surgery has always been the pursuit of clinicians. As a minimally invasive technique, single-hole laparoscopy is becoming more and more widely used in clinic, and achievements and difficulties will guide the development direction of further research in the future. This paper reviews the clinical application of single-hole laparoscopy in recent years and the status quo of its development.

A Suspended Silicon Single-Hole Transistor as an Extremely Scaled Gigahertz Nanoelectromechanical Beam Resonator.

Suspended single-hole transistors (SHTs) can also serve as nanoelectromechanical resonators, providing an ideal platform for investigating interactions between mechanical vibrations and charge carriers. Demonstrating such a device in silicon (Si) is of particular interest, due to the strong piezoresistive effect of Si and potential applications in Si-based quantum computation. Here, a suspended Si SHT also acting as a nanoelectromechanical beam resonator is demonstrated. The resonant frequency and zero-point motion of the device are ≈3 GHz and 0.2 pm, respectively, reaching the best level among similar devices demonstrated with Si-containing materials. The mechanical vibration is transduced to electrical readout by the SHT. The signal transduction mechanism is dominated by the piezoresistive effect. A giant apparent effective piezoresistive gauge factor with strong correlation to single-hole tunneling is extracted in this device. The results show the great potential of the device in interfacing charge carriers with mechanical vibrations, as well as investigating potential quantum behavior of the vibration phonon mode.

A Flexible Film toward High-Performance Lithium Storage: Designing Nanosheet-Assembled Hollow Single-Hole Ni-Co-Mn-O Spheres with Oxygen Vacancy Embedded in 3D Carbon Nanotube/Graphene Network.

Ternary transition metal oxides (TMOs) are highly potential electrode materials for lithium ion batteries (LIBs) due to abundant defects and synergistic effects with various metal elements in a single structure. However, low electronic/ionic conductivity and severe volume change hamper their practical application for lithium storage. Herein, nanosheet-assembled hollow single-hole Ni-Co-Mn oxide (NHSNCM) spheres with oxygen vacancies can be obtained through a facile hydrothermal reaction, which makes both ends of each nanosheet exposed to sufficient free space for volume variation, electrolyte for extra active surface area, and dual ion diffusion paths compared with airtight hollow structures. Furthermore, oxygen vacancies could improve ion/electronic transport and ion insertion/extraction process of NHSNCM spheres. Thus, oxygen-vacancy-rich NHSNCM spheres embedded into a 3D porous carbon nanotube/graphene network as the anode film ensure efficient electrolyte infiltration into both the exterior and interior of porous and open spheres for a high utilization of the active material, showing an excellent electrochemical performance for LIBs (1595 mAh g-1 over 300 cycles at 2 A g-1 , 441.6 mAh g-1 over 4000 cycles at 10 A g-1 ). Besides, this straightforward synthetic method opens an efficacious avenue for the construction of various nanosheet-assembled hollow single-hole TMO spheres for potential applications.
