OBJECTIVE: To compare the therapeutic efficacy and safety of local anesthesia and spinal anesthesia for the patients with varicocele (VC) who underwent microsurgical varicocelectomy (MV). METHODS: We retrospectively analyzed the data of VC patients who underwent MV treatment at the Andrology Department of the Affiliated Ruikang Hospital of Guangxi University of Chinese Medicine from May 2020 to March 2023. Cases with complete clinical data and follow-up evaluation were selected and divided into a control group (spinal anesthesia) and an observation group (local anesthesia) according to different anesthesia methods. The surgical time (including anesthesia time), visual analogue scale (VAS) score for pain, hospital stay, treatment cost, sperm concentration, forward motile sperm rate, and normal sperm morphology rate after three months of surgery, as well as postoperative complications and recurrence rate were compared between the two groups. RESULTS: A total of 107 eligible cases were included, with 56 cases in the control group and 51 cases in the observation group. There was no significant difference in the VAS score for pain during and after four hours of surgery, as well as postoperative complications, and recurrence rate between the two groups (P> 0.05). There was an significant increase in sperm concentration, forward motile sperm rate, and normal sperm morphology rate in both of two groups after three months of surgery (P<0.05). However, there was no significant difference between the two groups three months after surgery (P>0.05). The surgical time and hospital stay were shorter than those of the control group (P<0.05). And the treatment cost in observation group was lower than that of the control group (P<0.05). CONCLUSION Both local anesthesia and lumbar anesthesia for MV treatment of VC have good efficacy and safety. However, patients treated with MV under local anesthesia for VC have obvious advantages in terms of operation time (including anesthesia time), hospital stay, and treatment cost, which is worthy of clinical promotion and application.

Early-life stress (ES) leads to cognitive dysfunction in female adolescents, but the underlying neural mechanisms remain elusive. Recent evidence suggests that the cell adhesion molecules NECTIN1 and NECTIN3 play a role in cognition and ES-related cognitive deficits in male rodents. In this study, we aimed to investigate whether and how nectins contribute to ES-induced cognitive dysfunction in female adolescents. Applying the well-established limited bedding and nesting material paradigm, we found that ES impairs recognition memory, suppresses prefrontal NECTIN1 and hippocampal NECTIN3 expression, and upregulates corticotropin-releasing hormone (Crh) and its receptor 1 (Crhr1) mRNA levels in the hippocampus of adolescent female mice. Genetic experiments revealed that the reduction of dorsal CA1 (dCA1) NECTIN3 mediates ES-induced object recognition memory deficits, as knocking down dCA1 NECTIN3 impaired animals' performance in the novel object recognition task, while overexpression of dCA1 NECTIN3 successfully reversed the ES-induced deficits. Notably, prefrontal NECTIN1 knockdown did not result in significant cognitive impairments. Furthermore, acute systemic administration of antalarmin, a CRHR1 antagonist, upregulated hippocampal NECTIN3 levels and rescued object and spatial memory deficits in stressed mice. Our findings underscore the critical role of dCA1 NECTIN3 in mediating ES-induced object recognition memory deficits in adolescent female mice, highlighting it as a potential therapeutic target for stress-related psychiatric disorders in women.

Adverse experiences in early life have long-lasting negative impacts on behavior and the brain in adulthood, one of which is sleep disturbance. As the corticotropin-releasing hormone (CRH)-corticotropin-releasing hormone receptor 1 (CRHR1) system and nucleus accumbens (NAc) play important roles in both stress responses and sleep-wake regulation, in this study we investigated whether the NAc CRH-CRHR1 system mediates early-life stress-induced abnormalities in sleep-wake behavior in adult mice. Using the limited nesting and bedding material paradigm from postnatal days 2 to 9, we found that early-life stress disrupted sleep-wake behaviors during adulthood, including increased wakefulness and decreased non-rapid eye movement (NREM) sleep time during the dark period and increased rapid eye movement (REM) sleep time during the light period. The stress-induced sleep disturbances were accompanied by dendritic atrophy in the NAc and both were largely reversed by daily systemic administration of the CRHR1 antagonist antalarmin during stress exposure. Importantly, Crh overexpression in the NAc reproduced the effects of early-life stress on sleep-wake behavior and NAc morphology, whereas NAc Crhr1 knockdown reversed these effects (including increased wakefulness and reduced NREM sleep in the dark period and NAc dendritic atrophy). Together, our findings demonstrate the negative influence of early-life stress on sleep architecture and the structural plasticity of the NAc, and highlight the critical role of the NAc CRH-CRHR1 system in modulating these negative outcomes evoked by early-life stress.

OBJECTIVE: To investigate the expression level of miR-181b in CD19+ B lymphocytes of patients with chronic lymphocytic leukemia (CLL), to analyze the relationship between its expression and the prognosis of CLL patients, and to predict the potential target gene of miR-181b in CLL by using bioinformatics. METHODS: Eight-four patients with CLL treated in People's Hospital of Xinjiang Uygur Autonomous Region from June 2013 to June 2018 were selected. and 20 healthy people were selected as control group. RNA was extracted from CD19+B lymphocytes of peripheral blood by magnetic bead sorting, the expression level of miR-181b was detected, and it's expression differences in different IPI groups were analyzed. The correlation between the expression level of miR-181b and PFS of CLL patients also was analyzed. miR-181b target genes were predicted by online database and literatures, and gene annotation analysis and relevant signal pathway analysis were performed for candidate target genes. RESULTS: The expression level of miR-181b in CLL patients was significantly lower than that in control group (P＜0.01); The expression level of miR-181b in the low-risk group was higher than that in high-risk group and extremely high-risk group (P＜0.05), but there was no statistical difference between low-risk group and medium-risk group (P=1.00). The expression level of miR-181b in medium-risk group was higher than that in high-risk group and extremely high-risk group (P＜0.05), but there was no difference between high-risk group and extremely high-risk group (P=1.00). ROC curve results showed that the area under the curve (AUC) was 0.792 (P＜0.01).When the expression level of miR-181b was at the threshold value of 0.279, it showed a better sensitivity (62.9%) and specificity (91.8%). Survival analysis results suggested that compared with the high expression group, the miR-181b low expression group had poor PFS (log rank: P=0.047). Prediction of miR-181b by using the starBase, targetscan and picTar database and its combination with literature reports indicated that CARD11, ZFP36L1, RUNX1, NR4A3, ATP1B1, PUM1 and PLAG1 related with blood diseases, and up-regulated CARD11 and ZFP36L1 participated in lymphoid tumor formation by promoting cell proliferation and inhibiting cell aging. CONCLUSION The expression level of miR-181b in CLL group are significantly lower than that in the controls group, and the low expression of miR-181b relates with poor prognosis of CLL patients. Through bioinformatics prediction and combined with literature reports, it is speculated that CARD11 and ZFP36L1 as target genes of miR-181b may be participated in the occurrence and development of CLL. Further experiments are needed to verify this result.

Objective To evaluate the value of CT plus CTA in emergency surgical treatment of spontaneous intracerebral hemorrhage caused by brain arteriovenous malformations(AVM). Methods A total of 15 cases diagnosed with spontaneous intracerebral hemorrhage by emergent CT examination in the Second Affiliated Hospital of Wenzhou Medical University were retrospectively reviewed from May 2015 to June 2018, and subsequent emergent CTA examination was adopted to verify whether the patients had brain AVM that was responsible for the hemorrhage. After diagnosis, emergency surgical resection of the brain AVM and evacuation of hematoma were performed. Glasgow outcome score (GOS) was used to evaluated the outcome. A secondary DSA or CTA was performed from 2 weeks to 6 months post the operation. Results All 15 cases exanimated by emergent CT plus CTA were demonstrated to have brain AVM and intracranial hematoma. All the patients received emergency brain AVM resection and hematoma evacuation. The surgical finding during operation was in line with what was seen on emergent CT plus CTA, and all cases got total hematoma evacuation. Twelve cases received total brain AVM resection, and the other 3 cases received partial resection because the residual AVM foci existed in deep brain structures . After the operation, none had rebleeding at the surgical site. Follow-up DSA or CTA confirmed the 12 cases had total resection and the other 3 cases had partial resection. All patients were alive after the surgery and GOS scores during the follow-up time, from 2 weeks to 6 months after emergency surgery, were: 5 in 6 patients, 4 in 4 patients, 3 in 4 patients and 2 in 1 patient. Conclusions CT plus CTA can better show the relationship between vascular malformation, hematoma, and the adjacent anatomical structure, and therefore may contribute to intraoperative judgment and complete resection of vascular malformation. It is a practical imaging tool for the preoperative evaluation and emergency surgical treatment of spontaneous intracerebral hemorrhage caused by brain AVM.

Rehabilitation physician training is an important part of the development of rehabilitation medicine.Rehabilitation physician education in Taiwan has a complete and standardized training system,and rehabilitation physician training in mainland China is mainly achieved through standardized residency training.This article compares the differences in training processes for rehabilitation physicians in education in medical colleges and universities,residency training,and specialist training between Taiwan and mainland China.The results show that rehabilitation physician training in Taiwan is rigorous and orderly,with reasonable contents,clear objectives,strong specialty,and standardized assessment,while in mainland China,rehabilitation physicians in mainland China have insufficient training time,and there is a lack of detailed training plan and unified assessment standards.Rehabilitation physician training in mainland China needs to learn from advanced experience,further reform the training process,improve the operability of the overall education program,and perfect the training system of rehabilitation physicians.

Objective To investigate the association between maternal food group intakes during pregnancy and the risk of infantile eczema in a Chinese population. Methods A prospective birth cohort study was conducted and 523 women were recruited at 20-28 weeks of pregnancy in Guangzhou from 2017 to 2018. A validated 81-item quantitative food frequency questionnaire was used to assess maternal dietary intakes during the past month. Food items were divided into ten food groups according to the Chinese Dietary Guidelines. Offspring were followed up at 6 months by the symptom questionnaire of eczema. Multivariate Logistic regression model was conducted to evaluate the association between maternal food group intakes during pregnancy and the risk of infantile eczema. Results The cumulative incidence of eczema at 6 months was 51.8%. Maternal consumption of poultry was higher in the eczema group (27.62±25.20 g/d) than the control group (22.03±22.63 g/d, P=0.022). Comparing to the lowest quantile (Q1), higher maternal intake of poultry (Q4) and fish (Q3) were significantly associated with an increased risk of infantile eczema (OR=2.71, 95% CI=1.24-4.81; OR=2.38, 95% CI=1.23-4.59, respectively) after multivariate adjustment. Conclusion Higher intakes of poultry or fish during pregnancy were associated with an increased risk of infantile eczema in Chinese population.

Background: Depression affects approximately 5% of elderly people and its etiology might be related to chronic stress exposure during neurodevelopmental periods. In this study, we examined the effects of adolescent chronic social stress in aged mice on depressive behaviors and the excitatory-inhibitory (E/I) balance in stress-sensitive regions of the brain. Methods: Sixty-four adolescent, male C57BL/6 mice were randomly assigned to either the 7-week (from post-natal days 29 to 77) social instability stress (stress group, n = 32) or normal housing conditions (control group, n = 32). At 15 months of age, 16 mice were randomly selected from each group for a series of behavioral tests, including two depression-related tasks (the sucrose preference test and the tail suspension test). Three days following the last behavioral test, eight mice were randomly selected from each group for immunohistochemical analyses to measure the cell density of parvalbumin (PV⁺)- and calretinin (CR⁺)-positive gamma-aminobutyric-acid (GABA)ergic inhibitory inter-neurons, and the expression levels of vesicular transporters of glutamate-1 (VGluT1) and vesicular GABA transporter (VGAT) in three stress-sensitive regions of the brain (the medial pre-frontal cortex [mPFC], hippocampus, and amygdala). Results: Behaviorally, compared with the control group, adolescent chronic stress increased depression-like behaviors as shown in decreased sucrose preference (54.96 ± 1.97% vs. 43.11 ± 2.85%, t₍₂₂₎ = 3.417, P = 0.003) and reduced latency to immobility in the tail suspension test (92.77 ± 25.08 s vs. 33.14 ± 5.95 s, t₍₂₅₎ = 2.394, P = 0.025), but did not affect anxiety-like behaviors and pre-pulse inhibition. At the neurobiologic level, adolescent stress down-regulated PV⁺, not CR⁺, inter-neuron density in the mPFC (F_{(1, 39)} = 19.30, P < 0.001), and hippocampus (F_{(1, 42)} = 5.823, P = 0.020) and altered the CR⁺, not PV⁺, inter-neuron density in the amygdala (F_{(1, 28)} = 23.16, P < 0.001). The VGluT1/VGAT ratio was decreased in all three regions (all F > 10.09, all P < 0.004), which suggests stress-induced hypoexcitability in these regions. Conclusions Chronic stress during adolescence increased depression-like behaviors in aged mice, which may be associated with the E/I imbalance in stress-sensitive brain regions.
