Objective To examine the safety, efficacy and durability of totally endoscopic minimally invasive (TEMI) mitral valve repair in Barlow’s disease (BD). Methods A retrospective study was performed on patients who underwent mitral valve repair for BD from January 2010 to June 2021 in the Guangdong Provincial People’s Hospital. The patients were divided into a MS group and a TEMI group according to the surgery approaches. A comparison of the clinical data between the two groups was conducted. Results A total of 196 patients were enrolled, including 133 males and 63 females aged (43.8±14.9) years. There were 103 patients in the MS group and 93 patients in the TEMI group. No hospital death was observed. There was a higher percentage of artificial chordae implantation in the TEMI group compared to the MS group (P=0.020), but there was no statistical difference between the two groups in the other repair techniques (P>0.05). Although the total operation time between the two groups was not statistically different (P=0.265), the TEMI group had longer cardiopulmonary bypass time (P<0.001) and aortic clamp time (P<0.001), and shorter mechanical ventilation time (P<0.001) and postoperative hospitalization time (P<0.001). No statistical difference between the two groups in the adverse perioperative complications (P>0.05). The follow-up rate was 94.2% (180/191) with a mean time of 0.2-12.4 (4.0±2.4) years. Two patients in the MS group died with non-cardiac reasons during the follow-up period. The 3-year, 5-year and 10-year overall survival rates of all patients were 100.0%, 99.2%, 99.2%, respectively. Compared with the MS group, there was no statistical difference in the survival rate, recurrence rate of mitral regurgitation, reoperation rate of mitral valve or adverse cardiovascular and cerebrovascular events in the TEMI group (P＞0.05). Conclusion TEMI approach is a safe, feasible and effective approach for BD with a satisfying long-term efficacy.

OBJECTIVES: Managing patients with refractory head and neck cancer pain is one of the more challenging issues in clinical practice, and traditional intrathecal drug delivery also fails to provide adequate analgesia. There are currently no comprehensive and effective treatment methods. This study aims to observe the efficacy and safety of treating intractable head and neck cancer pain with morphine pump via lumbar approach to the prepontine cistern. METHODS: A total of 18 patients with intractable head and neck cancer pain treated with prepontine cistern morphine pumps were selected from the Department of Pain Management, Second Xiangya Hospital, Central South University between September 2019 and July 2023. Statistical analysis was performed on patients' preoperative and postoperative (1 week, 1 month, and 2 months after surgery), Numerical Rating Scale (NRS) scores, Self-Rating Depression Scale (SDS) scores, daily oral morphine consumption, the number of daily breakthrough pain episodes, and postoperative daily intrathecal morphine dosage. RESULTS: The NRS scores, SDS scores, daily oral morphine consumption, and the number of daily breakthrough pain episodes of patients at each time point after surgery were significantly lower than before surgery (all P<0.05). With the gradual increase in the dosage of intrathecal morphine, the daily oral morphine consumption of patients at each postoperative time point was significantly reduced compared to preoperative levels (all P<0.05). The complications related to the operation were mild, including nausea in 5 cases (31.3%), headache in 2 cases (12.5%); hypotension, urine retention, hypersomnia and constipation in 1 case (6.3% each), and no serious adverse events occurred. All improved and were discharged after symptomatic treatment. CONCLUSIONS The implantation of prepontine cistern morphine pump effectively controls intractable head and neck cancer pain, demonstrating characteristics of minimal invasiveness, mild side effects, and low medication dosage under the premise of standardized procedures.

Myocardial fibrosis is a serious cause of heart failure and even sudden cardiac death. However, the mechanisms underlying myocardial ischemia-induced cardiac fibrosis remain unclear. Here, we identified that the expression of sterile alpha and TIR motif containing 1 (SARM1), was increased significantly in the ischemic cardiomyopathy patients, dilated cardiomyopathy patients (GSE116250) and fibrotic heart tissues of mice. Additionally, inhibition or knockdown of SARM1 can improve myocardial fibrosis and cardiac function of myocardial infarction (MI) mice. Moreover, SARM1 fibroblasts-specific knock-in mice had increased deposition of extracellular matrix and impaired cardiac function. Mechanically, elevated expression of SARM1 promotes the deposition of extracellular matrix by directly modulating P4HA1. Notably, by using the Click-iT reaction, we identified that the increased expression of ZDHHC17 promotes the palmitoylation levels of SARM1, thereby accelerating the fibrosis process. Based on the fibrosis-promoting effect of SARM1, we screened several drugs with anti-myocardial fibrosis activity. In conclusion, we have unveiled that palmitoylated SARM1 targeting P4HA1 promotes collagen deposition and myocardial fibrosis. Inhibition of SARM1 is a potential strategy for the treatment of myocardial fibrosis. The sites where SARM1 interacts with P4HA1 and the palmitoylation modification sites of SARM1 may be the active targets for anti-fibrosis drugs.

OBJECTIVES: To compare the efficacy of toric implantable collamer lens (Toric-ICL) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for myopia correction in patients with moderate to high myopia complicated with astigmatism. METHODS: We retrospectively collected data from 64 patients (aged 18-42 years) with moderate to high myopia complicated with astigmatism (128 eyes) undergoing either Toric-ICL (28 patients/56 eyes) or FS-LASIK (36 patients/72 eyes) at our department between January, 2019 and December, 2020. The changes of uncorrected distance visual acuity (UCVA), spherical equivalent (SE), mean astigmatism correction index (CI), corneal endothelial cell density (ECD) and intraocular pressure (IOP) following the procedures were compared between the two groups. RESULTS: In FS-LASIK group, all the eyes (72/72) achieved an UCVA≥1.0, similar to the rate in Toric-ICL group (55/56 eyes; P=0.2374). The postoperative SE was also comparable between FS-LASIK and Toric-ICL groups [0.43±0.06 D (range: -1.0 to 1.50 D) vs 0.38±0.05 D (range: -0.75 to 1.00 D); P=0.56]. The mean astigmatism CI was significantly higher in FS-LASIK group than in Toric-ICL group (0.8561 vs 0.7176; P<0.0001), and 88.89% of the eyes in FS-LASIK group and 69.64% in Toric-ICL group had postoperative astigmatism ≤0.50 D. No significant changes were observed in postoperative corneal ECD in FS-LASIK group, whereas ECD decreased significantly after the procedure in Toric-ICL group (P=0.0057). The patients undergoing Toric-ICL exhibited no significant changes of postoperative IOP, but the patients receiving FS-LASIK had significantly reduced IOP after the procedure (P<0.001). CONCLUSIONS Although the patients included in Toric-ICL group had higher myopia and astigmatism, Toric-ICL still showed better predictability and efficacy for astigmatic correction in Toric-ICL group. Toric-ICL is an effective and safe equivalent of FS-LASIK for correcting moderate myopia but can be more advantageous for correcting high myopia with astigmatism.

Objective:The distribution characteristics of intrathecal drugs and the limitation of current catheterization techniques make traditional intrathecal analgesic treatment nearly useless for refractory craniofacial pain,such as trigemina neuralgia.This technical guideline aims to promote the widespread and standardize the application of intra-prepontine cisternal drug delivery via spinal puncture and catheterization. Methods:A modified Delphi approach was used to work for this guideline.On the issues related to the intra-prepontine cisternal targeted drug delivery technique,the working group consulted 10 experts from the field with 3 rounds of email feedback and 3 rounds of conference discussion. Results:For the efficacy and safety of the intra-prepontine cisternal targeted drug delivery technique,a consensus was formed on 7 topics(with an agreement rate of more than 80%),including the principles of the technique,indications and contraindications,patient preparation,surgical specifications for intra-prepontine cisternal catheter placement,analgesic dosage coordination,analgesic management,and prevention and treatment of complications. Conclusion:Utilizing the intra-prepontine cisternal drug infusion system to manage refractory craniofacial pain could provide advantages in terms of minimally invasive,secure,and effective treatment.This application can not only alleviate the suffering of individuals experiencing the prolonged pain but also support the maintenance of quality of life and dignity in their final moments,justifiing its widespread dissemination and standardized adoption in domestic and international professional fields.

ObjectiveTo investigate the pharmacological action and mechanism of Shuangshenling granules in treating chronic renal failure in rats，providing laboratory data to support clinical application of Shuangshenling granules. MethodSD rats （150-180 g），half males and half females in number，were used，with ten rats designated as the normal group，ten as the sham operation group，and the remaining rats undergoing chronic renal failure modeling induced by 5/6 nephrectomy. Two weeks after operation，serum creatinine （SCr） and blood urea nitrogen （BUN） levels were measured via orbital blood sampling to select successful model rats. Based on SCr values，the rats were evenly divided into the model group，Shenshuaining positive group （0.84 g·kg^-1·d^-1），and high，medium，and low dose groups of Shuangshenling granules （4.8，2.4，1.2 g·kg^-1·d^-1），with ten animals in each group. Each treatment group received drugs at 10 mL·kg^-1 via intragastric administration once daily for six weeks. At 2，4，6 weeks after administration，SCr，BUN，24-hour urine volume，total urinary protein （UTP），urinary creatinine （UCr），creatinine clearance rate （CCr），serum albumin （SAlb），and total serum protein （STP） were measured. Following the experiment，kidney tissues were dissected for pathological examination. The expression levels of autophagy-related proteins，including PTEN-induced kinase 1 （PINK1），E3 ubiquitin-protein ligase parkin （Parkin），and microtubule-associated protein 1 light chain 3B （LC3B），were detected by immunofluorescence. ResultCompared with the normal group，the model group exhibited significantly increased levels of SCr，BUN，24-hour urine volume，UTP，and UCr （P<0.01），and decreased levels of SAlb and STP （P<0.01）. CCr showed an initial increase followed by a decrease. Histopathological results revealed glomerular hyperplasia and atrophy，with varying degrees of mesangial cell reduction，blood stasis in the glomeruli，and significant widening of Bowman's capsule. Visceral parietal layer cells were displaced or absent，leading to incomplete and damaged glomeruli. A large number of protein casts were present in the proximal and distal convoluted tubules，with reduced and displaced cells，swelling in some tubules，and interstitial inflammatory exudation predominantly comprising lymphocytes and a small number of neutrophils. Compared with the model group，all dose groups of Shuangshenling granules significantly reduced levels of SCr，BUN，24-hour urine volume，UTP，and UCr （P<0.05，P<0.01） and increased SAlb and STP levels （P<0.01） at 2，4，and 6 weeks after administration. The three dose groups also improved CCr and alleviated renal pathological injury in varying degrees at 2-6 weeks after administration. Immunofluorescence results showed that the expression levels of PINK1，Parkin，and LC3B were significantly reduced in the model group compared with the normal group，whereas all dose groups of Shuangshenling granules significantly upregulated the expression levels of PINK1，Parkin，and LC3B compared with the model group. ConclusionShuangshenling granules significantly improved renal function and pathological injury in rats with chronic renal failure，likely through the upregulation of PINK1-mediated autophagy.

ObjectiveTo screen optimized protocol of acupuncture for post-prostatectomy urinary incontinence （PPUI） patients， and to provide evidence for clinical practice. MethodsMEDLINE， Embase， Cochrane Library， Web of Science， Chinese Biomedical Literature Database， China National Knowledge Infrastructure， WanFang and VIP databases were searched to collect randomized controlled trials of acupuncture for PPUI. The search was conducted from the establishment of the database to February 1， 2024， and the quality of the literature was evaluated to exclude the studies with a high risk of overall bias or modified Jadad ＜3， and constructed acupuncture protocol and performed meta-analysis. We used International Consultation on Urinary Incontinence Short Form （ICI-Q-SF） scores， quality of life scores， overall effective rate， and modified Jadad scores as beneficial indicators， and the number of acupoints selected， stimulation duration， the number of acupuncture， and the duration of the treatment course as costly indicators， to derive the standardized protocol matrix， and used the entropy method to determine the weights of the different decision-making indicators， and finally combined with the Technique for Order Preference by Similarity to Ideal Solution （TOPSIS） for comprehensive evaluation. ResultsNine studies met the criteria， and the acupuncture treatments involved were constructed as six protocols including electrical acupoint stimulation with low-frequency， electroacupuncture at four acupoints of sacral region， replenishing qi and tonifying kidney acupuncture， body acupuncture plus pelvic floor muscle training， auricular acupuncture， and electroacupuncture plus pelvic floor muscle training. The ICI-Q-SF， number of acupuncture sessions， and total effectiveness rate were given higher weights in the decision-making indexes， while the stimulation duration and the duration of treatment course were given lower weights； the entropy method of TOPSIS was used for the evaluation and proved that the best protocol was the electroacupuncture at four acupoints of sacral region which used continuous-wave electroacupuncture with a frequency of 2 Hz for 60 min each time， and required the needle sensation to radiate to the root of the penis， with the advantages of streamlined selection of acupoints， a significant reduction in ICI-Q-SF， and an increase in the effectiveness rate. ConclusionThe final optimized protocol was electroacupuncture at four acupoints of sacral region， which can provide an evidence-based basis for clinical decision-making and guideline development.
