Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective:To explore the surgical techniques and effects of transfer of the free chimeric functional thoracodorsal artery perforator flap (TDAPF) with latissimus dorsi in reconstruction of dynamic muscle and soft tissue defects in forearm.Methods:From January 2014 to December 2020, a total of 13 transfer surgery of free chimeric functional TDAPF with vascularised latissimus dorsi were performed in the Department of Hand Surgery, Plastic & Reconstructive Surgery, Ningbo Sixth Hospital, to reconstruct forearm composite defects. The patients were 12 males and 1 female with an average age of 33.2 years old. They all had open forearm injuries, with 5 in the left and 8 in the right. Removal of inactivated muscles, exploration and repair of blood vessels and nerves were performed in emergency surgery, and VSD were applied after the surgery. Phase II reconstructive surgery were completed within 4 to 12 days, with 7.5 days in average. The wounds and flaps sized were 9.0 cm×8.0 cm - 21.0 cm×11.0 cm and were 10.0 cm×9.0 cm - 22.0 cm×12.0 cm, respectively. The volume of transferred muscles ranged were 9.0 cm × 2.0 cm × 1.5 cm - 19.0 cm × 9.0 cm × 1.5 cm. Free chimeric functional muscular flaps were transferred to reconstruct the musculus flexor digitorum profundus in 4 patients, the musculus extensor digitorum communis in 8 patients, the musculus flexor carpi radialis in 3 patients, and the musculus flexor pollicis longus in 1 patient. Reconstruction of both of musculus flexor carpi radialis and musculus extensor digitorum communis with 2 functional sub-blocks of latissimus dorsi were performed in 3 patients. All donor sites were closed primarily. All patients were included in the postoperative follow-up to evaluate the appearance of flaps, range of motion of the digits, recovery of muscle strength and gripping power, at the outpatient clinics or through the telephone interview.Results:A total of 12 flaps survived uneventfully after reconstructive surgery. One flap developed a vascular crisis and it was rectified after surgical exploration. Postoperative follow-up ranged from 17 to 52 months, with a mean of 34.1 months. Appearances of limbs and flaps were good without obvious bulky, hyperpigmentation or scar contracture. Four patients with reconstructed musculus flexor digitorum profundus showed muscle strength recovery of M 4, with the fingertips measured lower than 2.0 cm from the centre of palm when clenching a fist, and the average gripping strength of the hand reached 27.5% (20%-35%) to the healthy side. Five patients with reconstructed musculus extensor digitorum communis showed muscle strength recovery of M 4, and there was no obvious limitation in fingers flexion and extension, with the average gripping strength of the hand reached 75.4% (65%-80%) to the healthy side. Of the 3 patients with reconstruction of both power muscles, the recovery of muscle strength of musculus flexor carpi radialis was at M 4 in all the 3 patients, and the musculus extensor digitorum communis was at M 4 in 1 and M 3 in 2 patients. However, the patient who received reconstruction of musculus flexor pollicis had no significant recovery in muscle strength. Conclusion:Transfer of free chimeric functional TDAPF combines the benefits of a perforator flap and a functional muscle transfer together. This surgical technique can effectively reconstruct damaged muscle groups in forearm and resulting in good hand movement. Additionally, it can also restore the aesthetic appearance of forearm, hence makes it an excellent option for complex wound coverage.

BACKGROUND: Current replacement procedures for stenosis or occluded arteries using prosthetic grafts have serious limitations in clinical applications, particularly, endothelialization of the luminal surface is a long-standing unresolved problem.METHOD: We produced a cell-based hybrid vascular graft using a bioink engulfing adipose-derived mesenchymal stromal cells (ADSCs) and a 3D bioprinting process lining the ADSCs on the luminal surface of GORE-Tex grafts. The hybrid graft was implanted as an interposition conduit to replace a 3-cm-long segment of the infrarenal abdominal aorta in Rhesus monkeys. RESULTS: Complete endothelium layer and smooth muscle layer were fully developed within 21 days post-implantation, along with normalized collagen deposition and crosslinking in the regenerated vasculature in all monkeys. The regenerated blood vessels showed normal functionality for the longest observation of more than 1650 days. The same procedure was also conducted in miniature pigs for the interposition replacement of a 10-cm-long right iliac artery and showed the same long-term effective and safe outcome. CONCLUSION This cell-based vascular graft is ready to undergo clinical trials for human patients.

Objective:To evaluate the feasibility of using positive anti-M-type phospholipase A 2 receptor(PLA 2R)antibody detection as a surrogate for renal biopsy in the diagnosis of idiopathic membranous nephropathy(IMN)in elderly Chinese. Methods:From June 2021 to March 2022, clinicopathological data of ninety-six elderly patients(≥60 years old)with positive anti-PLA 2R antibody detection(ELISA≥14 RU/ml), complete renal pathology records, and the exclusion of secondary disease and diabetes mellitus were collected from the Department of Nephrology, The First Affiliated Hospital of Zhengzhou University.Patients were divided into high eGFR group(≥60 ml·min -1·1.73 m -2)and low eGFR group(<60 ml·min -1·1.73 m -2), and the data were analyzed retrospectively. Results:Of the 96 patients, 95(99.0%)had IMN(1 in stage Ⅰ, 59 in stage Ⅱ, 34 in stage Ⅲ, and 1 in stage Ⅳ), and 1(1.0%)had atypical membranous nephropathy(AMN).For the IMN patients, 81(85.3%)had high eGFR and most IMN patients(66.7%)were in stage Ⅱ, with 10(12.3%)showing additional pathological findings, including mild mesangial proliferative IgA nephropathy(2 cases)and subacute tubulointerstitial nephropathy(2 cases).There were 14 patients(14.7%)with low eGFR, and most of them(57.1%)had stage Ⅲ IMN, with 10(71.4%)showing additional pathological findings.This percentage was higher than that in the high eGFR group( χ2=21.642, P<0.05).The most common additional pathological findings were acute tubular injury(4 cases)and ischemic kidney injury(2 cases). Conclusions:Positive anti-PLA 2R antibody detection is highly predictive of IMN in elderly Chinese patients, but it often co-exists with other pathological entities.The advantages of renal biopsy in detecting other pathological conditions and the risks associated with the procedure should be evaluated.

Metastases account for the overwhelming majority of cancer-associated deaths. The dissemination of cancer cells from the primary tumor to distant organs involves a complex process known as the invasion-metastasis cascade. The underlying biological mechanisms of metastasis, however, remain largely elusive. Recently, the discovery and characterization of non-coding RNAs (ncRNAs) have revealed the diversity of their regulatory roles, especially as key contributors throughout the metastatic cascade. Here, we review recent progress in how three major types of ncRNAs (microRNAs, long non-coding RNAs, and circular RNAs) are involved in the multistep procedure of metastasis. We further examine interactions among the three ncRNAs as well as current progress in their regulatory mechanisms. We also propose the prevention of metastasis in the early stages of cancer progression and discuss current translational studies using ncRNAs as targets for metastasis diagnosis and treatments. These studies provide insights into developing more effective strategies to target metastatic relapse.

Background The contracted family doctor services are the embodiment of the implementation of the new medical reform policy, and the transformation of the grass-roots health service mode. Studies have proved that the occupational stress in medical staff was at a high level. The enhancement of professional identity will contribute to strengthen team building，alleviate job burnout, and reduce turnover intention of family doctors. Objective To investigate the current situation of occupational identity among family doctor teams in Chengdu, to examine potential influencing factors of occupational identity, and to provide a reference for promoting career development and team building of family doctor teams. Methods Multi-stage random cluster sampling was adopted to enroll study participants form 46 primary healthcare centers where family doctor contract services were implemented among 23 districts and counties in Chengdu between March 4 and 26, 2021. A total of 2 681 family doctors participated in this survey. A self-reported survey was conducted to collect participants' demographic and occupational data. The Effort-Reward Imbalance (ERI）questionnaire was implemented to assess occupational stress. The Professional Identity Scale was used to appraise occupational identity. Results A total of 2 327 valid questionnaires were collected, with a valid recovery rate of 86.80%, involving 1 715 females (73.7%) and 612 males (26.3%), with dominant age groups of 26−35 years (43.3%) and 36−45 years (30.4%), a high proportion of being married (82.8%), having college (36.0%) and undergraduate (47.3%) education, a high proportion of primary titles (66.0%) and informal work contract (66.1%). About 88.7% of family doctor team workers reported occupational stress. The average score of occupational identity was (3.68±0.62) points. There were significant differences in occupational identity scores among different professional title, work contract, working years in medical institutions, income, and effort/reward ratio (EER) groups (P < 0.05). ERR was negatively correlated with occupational identity (r_s=−0.495, P<0.05）. The multiple regression model showed that occupational identity score in the non-staffed participants was lower than the score in the staffed ones (OR=0.429, 95%CI: 0.299−0.825). The occupational identity score in the participants having associate senior title or above was higher than in without professional title (OR=1.424, 95%CI: 1.194−2.328). The longer the working years, the higher the occupational identity score among the participants. The score of the more than 20 working years group was 1.820 times that of the less than 5 working years group (95%CI: 1.342−2.543). The higher the income, the higher the occupational identity score. The score of the 9001−12000 yuan per month group was 1.977 times that of the 1000−3000 yuan per month group (95%CI: 0.811−9.696) , and the score of the more than 12000 yuan per month group was 2.283 times that of the 1000−3000 yuan per month group (95%CI: 1.199−10.267）. Conclusion The family doctor team workers generally report occupational stress, and their occupational identity is at a medium level in Chengdu. Relevant managers should implement intervention measures against the main influencing factors to reduce their work tension and improve their occupational identity.

Ischemic-type biliary lesion (ITBL) refers to biliary tract injury caused by insufficient blood supply of hepatic artery, which is one of the main factors affecting the long-term survival and quality of life of liver transplant recipients. The incidence of ITBL is associated with cold and warm ischemia, acute and chronic rejection, cytomegalovirus infection and the bile effect, etc. The occurrence of ITBL is a complicated process involving with multiple factors and steps. The therapeutic option of ITBL is extremely limited. A large proportion of ITBL patients should undergo repeated liver transplantation. ITBL has become one of the most critical factors preventing further advancement of liver transplantation. Hence, it is of significance to strengthen prevention and explore more effective modalities. Recent studies have found that toxic injury of bile salts plays a central role in ITBL. Active regulation of bile components, regulation of bile acid-related receptor expression and blockage or activation of bile acid-related signaling pathways probably have potentials in the prevention and treatment of ITBL. In this article, the cytotoxicity of bile salts and the mechanism of bicarbonate umbrella in the incidence and progression of ITBL after liver transplantation were reviewed, aiming to provide reference for the diagnosis and treatment of ITBL.

【Objective】 To describe the BMI growth trajectories from birth to 24 months and examine the effects of fully breastfeeding time and breastfeeding duration on the BMI growth trajectories. 【Methods】 We conducted a follow-up study of a cohort of 1 388 eligible births. Height and weight were measured at birth, every 3 months to 12 months, and every 6 months to 24 months. Detailed demographic, feeding, activity and diseases data were also collected prospectively. Latent growth mixture modeling was conducted to model the BMI growth trajectories from birth to 24 months. Mixed-effects logistic regression analyses were made to examine the impacts of breastfeeding on this outcome. 【Results】 We identified six BMI trajectory patterns in the 1 285 infants analyzed and labeled them as follows: "normative growth" (26.6%), "normal-accelerating growth" (8.7%), "normal-decelerating growth" (11.7%), "lower-persistent growth" (6.6%), "rapid growth" (26.8%), and "rapid-accelerating growth" (19.5%). Mixed-effects logistic regression analyses revealed that fully breastfeeding ≥ 3 months could significantly decrease the risk of "rapid growth" (OR=0.71, 95% CI 0.51-0.98) and "rapid-accelerating growth" (OR=0.53, 95% CI 0.37-0.75). After adjustment for confounding factors, the relationship remained significant (OR=0.61, 95% CI 0.41-0.89; OR=0.46, 95% CI 0.31-0.68). Weaning before 6 months could significantly increase the risk of "rapid growth" (OR=1.76, 95% CI 1.19-2.61) and "rapid-accelerating growth" (OR=2.08, 95% CI 1.38-3.14). These associations persisted after adjustment for confounding factors (OR=1.69, 95% CI 1.08-2.71; OR=1.88, 95% CI 1.18-2.99). 【Conclusion】 In rural Western China, the main BMI growth trajectory patterns include "normative growth" , "rapid growth" , and "rapid-accelerating growth" . Prolonging breastfeeding may reduce excess weight gain during infancy.

Objective:To compare the prognosis of hemodialysis (HD) and peritoneal dialysis (PD) in end-stage renal disease (ESRD) patients without diabetes mellitus and identify related influencing factors.Methods:Patients who started hemodialysis with an arteriovenous graft or fistula or PD in the First Affiliated Hospital of Zhengzhou University from January 1, 2013 to February 1,2019 were included. They were followed up until May 1, 2019. The patients were divided into HD group and PD group according to the initial dialysis modality. Kaplan-Meier method was used to obtain survival curves, the Cox regression model was used to evaluate influence factors for survival rates, and the inverse probability of treatment weighting (IPTW) was used to eliminate influence of the confounders in the groups.Results:There were 371 patients with maintenance dialysis enrolled in this study, including 113 cases (30.5%) in HD group and 258 cases (69.5%) in PD group. At baseline, the scores of standard mean difference ( SMD) in age, body mass index (BMI), combined with cerebrovascular disease, Charlson comorbidity index (CCI), blood potassium, plasma albumin and hemoglobin between the two groups were greater than 0.1. The score of SMD decreased after IPTW, and the most data were less than 0.1, which meant that the balance had been reached between the two groups. The Kaplan-Meier survival curve showed that the cumulative survival rates had no significant difference for all-cause death before using IPTW between the two groups (Log-rank χ2=0.094, P=0.759). After adjusting for confounders with IPTW, the Kaplan-Meier survival curve showed that the cumulative survival rates still had no significant difference for all-cause death between the two groups (Log-rank χ2=2.090, P=0.150). Univariate Cox regression analysis showed that there was no significant difference between HD and PD on survival rates in ESRD patients without diabetes mellitus for all-cause death (PD/HD, HR=1.171, 95% CI 0.426-3.223, P=0.760). Multivariate Cox regression analysis showed that there was no significant difference between HD and PD on survival rates in ESRD patients without diabetes mellitus (PD/HD, HR=1.460, 95% CI 0.515-4.144, P=0.477), and high plasma albumin ( HR=0.893, 95% CI 0.813-0.981, P=0.019) was an independent protective factor for survival in ESRD patients without diabetes mellitus. There was still no significant difference between HD and PD on survival rates in ESRD patients without diabetes mellitus after using IPTW (PD/HD, HR=1.842, 95% CI 0.514-6.604, P=0.348). Conclusion:The difference of cumulative survival rates between HD and PD is not significant in ESRD patients without diabetes mellitus.

Objective: To investigate the short-term efficacy and adverse events of chemotherapy combined with androgen-deprivation therapy in high-volume metastatic hormone sensitive prostate cancer. Methods: From March 2015 to August 2017, 55 patients with high-volume metastatic hormone sensitive prostate cancer were enrolled at Department of Urology, Fudan University Shanghai Cancer Center receiving chemotherapy combined with androgen-deprivation therapy. The age was 65(8) years (M(Q_R)) (range: 46 to 79 years). Patients were enrolled in the study for continuous androgen-deprivation therapy (medical or surgical castration), combined with docetaxel 75 mg/m² intravenous injection on the first day, repeated every 21 days (6 cycles). Endpoints included overall survival, progression-free survival of prostate cancer, prostate specific antigen (PSA) response rate, and adverse events. Results: The follow-up time was 21.2(11.7) months. The PSA value before chemotherapy was 144.9(415.3) μg/L. The days in patients undergoing androgen deprivation therapy before chemotherapy was 14(23) days. Four patients (7.3%) presented 0 in Eastern Cooperative Oncology Group scoring system and 51 patients(92.7%) presented 1. Thirty-nine patients (70.9%) completed more than 6 cycles of combined chemotherapy, 17 patients (30.9%) showed PSA<0.2 μg/L at 6 months after treatment, and 14 patients (25.5%) showed PSA<0.2 μg/L at 12 months after treatment. Twenty-eight patients (50.9%) had grade 3 to 4 neutropenia and 1 patient (1.8%) developed infectious neutropenia and died. Nausea and vomit occurred in 16 patients (29.1%). Twelve patients (21.8%) underwent dose adjustment due to adverse events in blood system. Conclusions The short-term effect was confirmed in high-volume metastatic hormone sensitive prostate cancer using chemotherapy combined androgen-deprivation therapy, and the long-term effect remains to be seen. Myelosuppression during chemotherapy requires close attention, and taking timely examination is recommended.
