Objective:To compare the clinical efficacy of ultrasound-guided spinal nerve block (SNB) and paraverteral nerve block (PVB) in treating postherpetic neuralgia.Methods:A total of 52 patients with postherpetic neuralgia who visited the Pain Clinic of the Xiangya Hospital, Central South University from February 2020 to December 2022 were selected and randomly divided into an ultrasound-guided SNB group and a PVB group using a random number table method, with 26 patients in each group. Patients in the SNB group received ultrasound-guided spinal nerve block therapy; The PVB group received ultrasound-guided paraverteral nerve block treatment. Visual Analog Scale (VAS) scores, 36-Item Short Form Survey (SF-36) scores, and total effective rate were observed in two groups of patients before treatment, 2 weeks after treatment, 1 month after treatment, 3 months after treatment, and 6 months after treatment. Complications during treatment were also observed.Results:The total effective rates of SNB group patients at 1, 3, and 6 months after treatment were significantly higher than those of PVB group (all P<0.05). After treatment, the VAS scores of both groups of patients at each time point were significantly reduced compared to before treatment (all P<0.05); The VAS scores of patients in the SNB group were lower than those in the PVB group at 1, 3, and 6 months after treatment, but the difference was not statistically significant (all P>0.05). There was no statistically significant difference in Physical Component Summary (PCS) and Mental Component Summary (MCS) scores between SNB and PVB groups before nerve block treatment (all P>0.05). The MCS and PCS scores of the two groups of patients were significantly higher than before treatment at 2 weeks, 1 month, 3 months, and 6 months after treatment (all P<0.05). The MCS scores of the SNB group were significantly higher than those of the PVB group at 2 weeks, 1 month, 3 months, and 6 months after treatment (all P<0.05), but there was no statistically significant difference in PCS scores between the two groups (all P>0.05). Both groups of patients did not experience any serious complications related to the treatment in this study during the follow-up period. Conclusions:Both ultrasound-guided spinal nerve block and paraverteral nerve block can safely and effectively treat postherpetic neuralgia. The clinical effect of ultrasound-guided spinal nerve block in treating postherpetic neuralgia is better than that of paraverteral nerve block.

Pain caused by surgery is an important clinical issue that seriously affects postoperative rehabilitation and health-related quality of life. Failure to effectively manage postoperative pain not only leads to a decrease in patient quality of life, increases medical expenses, but also has a negative impact on patient recovery. Therefore, it is of great clinical significance to address the challenges of acute postoperative pain management, find effective management strategies, and improve the quality of pain management. This article summarizes the current status of acute postoperative pain management in recent years, including the mechanism of pain occurrence, pain assessment methods, drug and non drug management strategies, and predictive factors for chronic postoperative pain. It also looks forward to future research directions and application prospects.

Objectives:To analyze the clinical features of juvenile myelomonocytic leukemia (JMML) and investigate the characteristics of diagnosis and treatment of this disease.Methods:The clinical data of seven children patients with JMML who received treatment in The First Affiliated Hospital of Xinxiang Medical University between April 2015 and February 2020 were retrospectively analyzed. The clinical efficacy of different treatments was analyzed.Results:The median age at diagnosis of JMML was 8 months and 4 days for seven children patients. Fever was the principal cause of treatment, and it was mostly accompanied by hepatosplenomegaly. The median value of peripheral blood leukocyte count was 36.1 × 10 9/L, and it was 4.5 × 10 9/L for mononuclear cell count, 88 g/L for hemoglobin level, and 47 × 10 9/L for platelet count. Myeloid immature cells were found in peripheral blood smears of six patients. Chromosome examination results revealed 7-monomer in one patient, and normal karyotype in six patients. Hemoglobin level was increased in six patients. Gene detection results revealed PTPN11+NF1 mutation in one patient, N-RAS mutation in two patients, and K-RAS mutation in one patient. Three patients gave up treatment, three patients received low-intensity chemotherapy , and these six patients died of complicated infection. One patient received allogeneic hematopoietic stem cell transplantation and the patient survived without any event after 14 months of follow-up. Conclusion:The age of JMML onset is low. JMML has poor clinical specificity. Gene detection is helpful for early diagnosis of JMML. Low-intensity chemotherapy can prolong survival period, but it can not improve prognosis. Infection is the principal cause of death in patients with JMML. Hematopoietic stem cell transplantation is the only possible method to cure the disease.

Enhanced recovery after surgery (ERAS) is mainly based on evidence-based medicine to implement a series of measures to optimize perioperative management, reduce patients′ physiological and psychological trauma stress during perioperative period, reduce patients′ functional damage and promote patients′ functional recovery, so as to achieve rapid rehabilitation. ERAS has been widely used in clinic and achieved good clinical results. However, it still faces a series of problems that need further research to clarify the clinical path of ERAS required by different patients and different surgical methods. In particular, it is necessary to strengthen the research on risk factors of ERAS, minimally invasive surgery, goal-directed fluid therapy, anesthesia and postoperative pain management technology, pre rehabilitation and postoperative rehabilitation technology, and implement ERAS guided by the best outcome in the perioperative period.

Objective:Through retrospective analysis of perioperative management data of ambulatory thyroid surgery under the concept of enhanced recovery after surgery (ERAS), we provide foundation for the safe implementation of ambulatory thyroid surgery.Methods:From January 2019 to December 2019, patients undergoing thyroid surgery were enrolled in the study under the concept of ERAS at the ambulatory surgery center of Xiangya Hospital, Central South University. Data of patients during perioperative period were collected, including adverse events, anesthesia recovery, postoperative and post-discharge recovery were recorded.Results:This study was included 703 cases of patients, thyroid nodules in 374 cases, thyroid malignant tumor in 329 cases. There were no significance difference in the operation time, anesthesia time, wake up of time, and postanesthesia care unit (PACU) time between the two groups (all P>0.05). No hypertension, hypotension, tachycardia, bradycardia or other arrhythmias occurred during perioperative period. No adverse events such as intraoperative awareness and delay of wake up occurred. No severe pain, nausea, vomiting, dizziness and other discomfort occurred after surgery. All 703 patients were discharged from hospital within 24 hours. Conclusions:Anesthesiologists participate in patient management according to the perioperative medicine requirements, and ambulatory thyroid surgery may be performed safely under the concept of ERAS.

It is necessary to use objective and accurate methods to assess the changes of the consciousness of patients emergencing from general anesthesia. In this way, adverse medications during the waking period can be avoided, and it can ensure the stable and safe recovery of consciousness of the patients, quickly remove the adverse factors affecting the patients, and strive to reduce the occurrence of complications during the waking period. This article briefly reviews the research progress of bispectral index and other common clinical anesthesia depth monitoring techniques used to assess the changes of consciousness of patients awakening from general anesthesia, and explores the regular pattern of recovery of consciousness in patients awakening from general anesthesia, in order to reduce complications in the recovery period .

To investigate whether mammalian target of rapamycin (mTOR) signaling pathway is involved in peripheral nerve injury-induced hyperalgesia through activation of spinal dorsal astrocytes in rats.
 Methods: A total of 30 male Sprague-Dawley (SD) rats were randomly divided into 6 groups (n=5): the 1 day group (D1 group), the 4 days group (D4 group), the 7 days group (D7 group), the 14 days group (D14 group), the normal group and the sham group. The sciatic nerve chronic constriction injury (CCI) model was established in the D1, D4, D7 and D14 group. The normal group received no treatment while the sham group was only exposed the sciatic nerve. Paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL) were measured at the 1st, 4th, 7th, and 14th day after CCI in the different groups. Lumbar spinal cord were harvested on the 1st, 4th, 7th and 14th day in the D1, D4, D7, D14 group correspondingly, which were harvested on the 14th day in the normal group and the sham group. Distribution of mTOR in rat spinal cord was assessed by immunohistochemistry. The expressions of mTOR mRNA and protein in the spinal cord in different groups were determined by real-time PCR and Western blotting, respectively. Another 30 male intrathecal catheterized SD rats were randomly divided into 6 groups (n=5): a blank group, a CCI group, a CCI+early rapamycin (RAPA) group, a CCI+early dimethylsulfoxide (DMSO) group, a CCI+ later RAPA group, and a CCI+later DMSO group. The blank group didn't received any treatment; The CCI group was carried out the treatment of CCI model in the left hind limbs. 10 μL of 1% RAPA was given to the CCI+early RAPA group intrathecally at 4 hours after CCI for 3 days; the CCI+later RAPA group were treated with the same dose of RAPA on the 7th days after CCI for 3 days; the CCI+early DMSO group and the CCI+later DMSO group were injected with the same volume of 4% DMSO at the corresponding time as controls. The PWTL and PWMT were measured before and after intrathecal catheterization, and every other day after CCI. The lumbar spinal cords were selected and the expression of glial fibrillary acidic protein (GFAP) in spinal dorsal horn were examined by immunohistochemistry in the 14th day after CCI.
 Results: The immunohistochemistry positive particles of mTOR were widely distributed in the cytoplasm of the normal spinal neurons. Compared with the base line, the PWMT in the D14 group on the 1st, 4th, 7th and 14th day after CCI were significantly lower, and the PWTL on the 4th, 7th and 14th day after CCI were also significantly lower (P<0.05 or P<0.01). The expressions of mTOR mRNA and protein in the CCI groups (D1, D4, D7 and D14 group) were significantly increased than those in the normal group (P<0.05 or P<0.01). Compared with the CCI+early DMSO group, the PWMT and PWTL in the CCI+early RAPA group were obviously increased on 4th, 6th, 8th, 10th, 12th or 14th day after CCI (P<0.05 or P<0.01); compared with the CCI+later DMSO group, the PWMT and PWTL in the CCI+later RAPA group were also significantly increased at the 8th, 10th or 14th day after CCI (P<0.01 or P<0.05). The GFAP immunohistochemistry positive area and absorbance value in the dorsal horn of the lumbar spinal cord in the CCI rats were decreased in the CCI+early RAPA group compared with the CCI+early DMSO group (P<0.05 or P<0.01), and which were also decreased in the CCI+later RAPA group compared with the CCI+later DMSO group (P<0.05 or P<0.01).
 Conclusion: mTOR signaling pathway may be involved in hyperalgesia induced by peripheral nerve injury via spinal astrocyte activation in the dorsal horn of the spinal cord.

Ambulatory surgery is widely practiced in developed countries Since it was first proposed by Dr.James Nicoll.There are significant differences in anesthesia management between ambulatory surgery and hospital surgery.With the development of minimally invasive surgical and anaesthetic techniques,short-acting anesthetics,the use of ambulatory surgery has grown rapidly.Anesthesiologist is a necessary condition for the safety of perioperative patients and the implementation of ambulatory surgery.Anesthesiologist participates in preoperative evaluation and choice of patients,intraoperative anesthesia,safe discharge after operation,as well as the management of postoperative pain and complications in the perioperative period.For successful ambulatory anesthesia,the anesthesiologist must consider various factors relating to the patient and surgery.Patient selection is a particularly important factor.Appropriate surgical and anesthetic techniques shoull be used to minimize postoperative complications,especially postoperative pain,nausea,and vomiting.It has become increasingly important to identify patients at risk of perioperative complications and to use appropriate methods to decrease these risks.Future studies should be focus on data derived from ambulatory surgery patients and prospective,randomized,double -blind studies in a large population of patients in order to first identify the patient at risk and the quality system of ambulatory surgery anesthesia,subsequently to use drugs and techniques that reduce these perioperative risks and perioperative complications,allow quick recovery from anesthesia and improve the quality of ambulatory surgery.
