To summarize the distribution characteristics of human papillomavirus(HPV) infection types in patients with cervical squamous intraepithelial lesion(SIL) and cervical cancer(CC), and to explore the impact of HPV vaccination, HPV infection types, and general clinical data on different grades of cervical lesions.

Objective To compare the clinical outcomes of subxiphoid robot-assisted thoracoscopic surgery (SRATS) and intercostal robot-assisted thoracoscopic surgery (IRATS) in the treatment of anterior mediastinal tumors. Methods A retrospective analysis was conducted on patients with anterior mediastinal tumors who underwent robot-assisted surgery in the Department of Thoracic Surgery, Gansu Provincial Hospital, from May 2020 to July 2022. According to the surgical approach, patients were divided into an SRATS group and an IRATS group. Perioperative data were compared between the two groups. Results A total of 87 patients were included. There were 41 patients in the SRATS group [23 males, 18 females; mean age, (44.51±11.28) years] and 46 patients in the IRATS group [21 males, 25 females; mean age, (46.67±8.76) years]. Compared with the IRATS group, the SRATS group had significantly less intraoperative blood loss [(24.41±6.67) mL vs. (37.93±9.23) mL, P<0.001], shorter postoperative drainage duration [(1.73±0.59) days vs. (2.54±0.50) days, P<0.001], lower postoperative drainage volume [(94.46±34.08) mLvs. (116.72±24.90) mL, P=0.001], lower visual analogue scale (VAS) pain scores on postoperative day 1 [(3.66±0.76) points vs. (4.15±0.84) points, P=0.005] and day 3 [(2.41±0.59) points vs. (2.89±0.82) points, P=0.003], shorter postoperative hospital stay [(4.12±0.81) days vs. (4.98±1.02) days, P<0.001], and lower hospitalization costs [(4.51±0.65) ten thousand yuan vs. (4.86±0.68) ten thousand yuan, P=0.020]. There were no statistical differences between the two groups in operative time or incidence of postoperative complications (P>0.05). Conclusion Both SRATS and IRATS are safe and effective for the treatment of anterior mediastinal tumors. However, SRATS is less invasive and more conducive to enhanced postoperative recovery.

OBJECTIVE This study investigated the clinical implications of endothelial cell-specific molecule 1(ESM-1)in obstructive sleep apnea(OSA)patients,with particular focus on its dynamic correlation with adhesion molecules,aiming to elucidate the regulatory role of ESM-1 in OSA-associated vascular endothelial impairment.METHODS This cross-sectional study enrolled participants undergoing polysomnography(PSG)at the Sleep Medicine Center of Beijing Anzhen Hospital,Capital Medical University between March 2017 and January 2018.Based on the inclusion criteria,161 participants were ultimately included and divided into OSA group(n=118)and control group(n=43).Demographic data and polysomnography parameters were collected.We used a powerful high-throughput Multiplex Immunobead Assay technology to simultaneously test plasm cytokines levels of ESM-1,inter-cellular adhesion molecule 1(ICAM-1),vascular cell adhesion molecule 1(VCAM-1).Circulating C-reactive protein(CRP)and homocysteine(Hcy)were detected by routine blood chemistry panel.RESULTS Circulating ESM-1 levels were significantly elevated in patients with OSA compared with healthy controls[819.73(612.36-1393.47)pg/ml]vs.[286.17(114.48-513.81)pg/ml,P<0.001].After adjusting for confounding factors,we found that circulating ESM-1 levels were an independent risk factor for OSA(odds ratio=2.162,95%CI=1.522-3.072,P<0.001)and circulating ESM-1 levels were positively associated with ICAM-1 and VCAM-1 levels(β=1.977,95%CI=1.429-2.734,P<0.001).CONCLUSION Circulating ESM-1 levels were significantly increased in patients with OSA,which is closely related with adhesion molecules levels.ESM-1 may be a surrogate endothelial dysfunction marker and an independent risk factor for OSA.

Objective:To explore the learning curve of primary urologists mastering Holmium laser enucleation of the prostate for the treatment of large volume benign prostatic hyperplasia (BPH).Methods:The clinical data of 92 patients with larger volume BPH who received HoLEP performed by a urologist in Beijing Friendship Hospital Pinggu Campus, Capital Medical University were retrospectively reviewed. 92 patients were divided into group A (1-23 cases, n=23), group B (24-46 cases, n=23), group C (47-69 cases, n=23), and group D (70-92 cases, n=23) based on the sequence of surgery. The clinical characteristics, including prostate volume, operation time, enucleation efficiency, indwelling catheter time, decrease value of hemoglobin, intraoperative blood transfusion, perioperative complications, and international prostate symptom score (IPSS), quality of life (QOL) score, Qmax, and postvoid residual urine (PVR) at 3 months postoperatively were compared between the four groups. Measurement data were expressed as mean ± standard deviation ( ± s), one-way analysis of variance was used for comparisons among multiple groups, and t-test was used for comparisons between two groups. Count data were expressed as the cases and percentage, and the Chi-square test was used for comparison between groups. Results:There were significant differences among the four groups in terms of operation time [(94.43±8.26) min, (86.39±5.89) min, (70.70±5.64) min, (64.70±4.23) min, P=0.001], enucleation efficiency [(0.90±0.08) mL/min, (1.01±0.07) mL/min, (1.23±0.12) mL/min, (1.34±0.12) mL/min, P=0.001], decrease value of hemoglobin [(25.98±1.39) g/L, (23.27±1.49) g/L, (20.03±1.07) g/L, (18.49±0.96) g/L, P=0.001] and indwelling catheter time [(5.91±1.54) d, (5.35±1.27) d, (3.39±0.72) d, (3.04±0.64) d, P=0.001]. Compared with group C and group D, the operation time was longer, the enucleation efficiency was lower, the decrease value of hemoglobin before and after the operation was higher, and the indwelling catheter time was longer, the above differences were all statistically significant ( P<0.05). However, there was no statistically significant difference between group A and group B, or group C and group D ( P>0.05). Among the 92 patients, only 3 patients received blood transfusion during operation, including 2 patients in group A and 1 patient in group B. 2 patients underwent surgical complications during the perioperative period. Among them, 1 patient suffered bladder wall injury due to improper operation of the tissue pulverizer in group A, and 1 patient developed prostatic capsule perforation in group B. Furthermore, after 56 cases of operation, a primary urologist can perform HoLEP surgery quickly and safely. Conclusion:The learning curve of a primary urologist mastering HoLEP for larger volume (≥ 80 mL) BPH was 56 procedures, and the operation efficiency and safety were significantly improved.

The irrational use of Chinese patent medicines （CPM） is becoming more and more prominent， which makes the demand for clinical practice guidelines of CPM gradually increase. In order to make domestic scholars understand the latest developments and existing problems of the CPM guidelines， and promote its development， this paper introduced the concept of CPM guidelines， summarized the characteristics of the two development modes， namely “taking CPM as the key” and “taking disease/syndrome as the key”， and analyzed the current methodological status of developing and reporting CPM guidelines. Based on the existed problems， three suggestions have been put forward to optimize the quality of CPM guidelines， which were clarifying the target users and scope of CPM guidelines， establishing an open and transparent mechanism of the personnel involvement and process steps， and formulating implementable and operable recommendations for the use of CPM.

This paper summarized the key points and methods in terms of the establishment of the guideline working group and the management of conflict of interests， trying to provide reference for the development of clinical practice guidelines for Chinese patent medicine （CPM）. The establishment of the working group is the first important step for developing CPM guidelines. Considering the characteristics of the clinical practice guidelines for CPM， this study suggests that the three key elements of ‘multidisciplinarity’， ‘clinical relevance’ and ‘geographical representativeness’ should be put focus on when forming the working group. The guideline advisory committee， clinical expert group， evidence systematic evaluation group， secretary group and the external review group should be established. All group members should clarify the conflict of interest， and the process and management method of the conflict of interest should be clearly reported.

The systematic and comprehensive introduction and interpretation of the Reporting Checklist of Clinical Practice Guidelines for Chinese Patent Medicines V1.0 is conducive to the presentation of high-quality clinical practice guidelines for Chinese patent medicines （CPMs）， thus improving their dissemination and use. The Reporting Checklist of Clinical Practice Guidelines for Chinese Patent Medicines V1.0 specifies the requirements for clear， complete and transparent reporting of the whole process of developing CPMs guidelines， containing 4 domains， 17 topics and 43 items， and involving the basic information， recommendations and methods of guideline development. Especially， it details the items related to the rules and regulations of the use of CPMs in the recommendations， which is helpful for improving the completeness， scientificity and practicality of the reporting of CPMs guideline.

The lack of direct evidence is an important problem faced in the formation of recommendations in rapid living guidelines of traditional Chinese medicine under public health emergencies， and the supplementation of indirect evidence can be a key method to solve this problem. For the collection of evidence， the type of evidence required， including direct and indirect evidence， should be clarified， and ‘direct first’ principle for selecting evidence can be set to standardize and accelerate the guideline development. When integrating evidence， recommendations can be formed directly if there is sufficient direct evidence， while regarding insufficient direct evidence， recommendations need to be supplemented and improved by integrating indirect evidence. In addition， when the body of evidence contains evidence from multiple sources， it is suggested to rate the evidence according to “higher rather than lower” principle. Finally， when forming recommendations， the level of evidence， safety and economic efficiency should be taken into consideration to determine the strength of the recommendation.

Objective To investigate the effects of miR-4531/CX3CL1 signaling pathway on the vascular injury in preeclampsia, and to search possible targets for early diagnosis and prevention of preeclampsia. Methods Placental tissue samples were obtained from 10 patients with late-onset preeclampsia and 10 normal pregnant women in the Obstetrics and Gynecology Department of Minhang Hospital, Fudan University from October 2021 to December 2022. The levels of miR-4531 and CX3CL1 were evaluated by qRT-PCR. Cell transfection was performed by lipofectamine 2000 in vitro. The binding relationship between miR-4531 and CX3CL1 was determined by luciferase reporter assay. The apoptosis of neutrophils, the migration, repair, colony formation and cell-free DNA (cfDNA) release of human umbilical vein endothelial cells (HUVECs) were detected. Results MiR-4531 was significantly downregulated, and CX3CL1 was upregulated in placental tissues of preeclampsia patients (P＜0.05). Luciferase report assay confirmed the direct binding relationship between miR-4531 and CX3CL1. Upregulation of miR-4531significantly promoted the migration, proliferation, repair, and inhibited cfDNA release of HUVECs and neutrophils apoptosis in medium under hypoxic condition (P＜0.05). However, downregulation of miR-4531 obviously inhibited the proliferation, migration, repair, and enhanced cfDNA release of HUVECs and neutrophils apoptosis in medium under hypoxic condition (P＜0.05). Conclusions The miR-4531is downregulated in placental tissues of preeclampsia parients and is a potential therapeutic target for preeclampsia. It might cause endothelial damage and an abnormal hypercoagulable state under hypoxic condition by targeting and regulating the CX3CL1 pathway.

To reduce the subjectivity and uncertainty present in the current international methods of drug value pricing when converting value into monetary prices,based on the hedonic pricing theory,it considers the post-negotiation price between manufacturers and payers as a reasonable price reference in the value pricing of Chinese patent medicine.By constructing an indicator system for the characteristics of Chinese patent medicine,it selects and measures the value characteristic variables that affect the price of Chinese patent medicine.It serves as the theoretical foundation and research basis for establishing a Hedonic price model between characteristic price variables and negotiation prices,thereby promoting the enhancement of rationality and objectivity in value-guided pricing of Chinese patent medicine.
