Objective:To investigate the application effect of quadratus lumborum block (QLB) combined with less opioid anesthesia analgesia in laparoscopic total hysterectomy (LTH) in elderly patients with uterine prolapse.Methods:A total of 86 elderly patients with uterine prolapse who received LTH in the Langfang People’s Hospital from Jan. 2021 to Oct. 2023 were prospectively selected and divided into group A ( n=42) and group B ( n=44) according to the random number table method. Group A received transversus abdominis block (TAPB) + general anesthesia, and group B received QLB combined with less opioid anesthesia + general anesthesia. The pain duration at different time points after operation [Numeric Rating Scale (NRS) method to evaluate resting incision and visceral pain] was compared between the two groups. The dosage of opioids and the additional analgesia rate were compared between the two groups. The sleep quality of the two groups before and 72 hours after operation was compared, and the adverse reactions of anesthesia were counted. Results:Compared with 6 h after operation, NRS scores of resting incision pain and visceral pain in the two groups decreased gradually at 12, 24 and 48 h after operation, and it was lower in group B than in group A. There were statistically significant differences between groups ( P<0.05) . Dosage of sufentanil and remifentanil in group B was lower than that in group A, and the postoperative additional analgesia rate in group B (9.09%) was lower than that in group A (28.57%) ( P<0.05) . 72 hours after surgery, the sleep efficiency and total sleep time of patients in both groups were lower than those before surgery, and they were higher in group B than in group A; The awakening time and number of awakenings in both groups were higher than those before surgery, while they were lower in group B than in group A ( P<0.05) . The total incidence of adverse reactions in group B was 4.76% (2/44) , lower than 23.81% (10/42) of group A ( P<0.05) . Conclusion:QLB combined with less opioid anesthesia analgesia can effectively reduce the degree of incision and visceral pain after LTH in elderly patients with uterine prolapse, reduce the amount of opioids used during operation and the rate of additional analgesia, and reduce the incidence of adverse reactions of anesthesia.

Objective To observe the effect of quadratus lumborum block(QLB)anesthesia on intraoperative blood gas indexes and postoperative recovery in female uremic patients with peritoneal dialysis catheterization.Methods A total of 70 female uremic patients with peritoneal dialysis catheterization admitted to Langfang People's Hospital from January 2021 to December 2023 were selected as the research objects.According to the random number table method,they were divided into the control group and the study group,with 35 cases in each group.The control group was given conventional local infiltration anesthesia,whereas the study group was given QLB anesthesia.The changes of mean arterial pressure(MAP),heart rate(HR),blood gas indexes[pulse oxygen saturation(SpO2),arterial partial pressure of carbon dioxide(PaCO2)]and numeric rating scale(NRS)score,at different points pain factors[5-hydroxytryptamine(5-HT),substance P(SP),norepinephrine(NE)]before operation and 24 hours after operation,postoperative recovery(time to get out of bed for the first time,exhaust time,length of hospital stay)and adverse reactions were observed in the two groups.Results There was no significant difference in MAP,HR,blood gas index and NRS score between the two groups at the admission.The MAP,HR,PaCO2 in the study group were significantly lower than those in the control group during skin incision,rectus abdominis separation,catheterization,suture,and leaving the room,and SpO2 was significantly higher than that in the control group,and NRS score in the study group were significantly lower than those in the control group during skin incision,rectus abdominis separation,catheterization,suture(all P<0.05).There was no significant difference in the levels of 5-HT,SP and NE between the two groups before operation,but the levels of 5-HT,SP and NE at 24 hours after operation were significantly higher than those before operation,but the levels of 5-HT,SP and NE in the study group were lower than those in the control group.The first ambulation time,exhaust time and hospitalization time in the study group were significantly shorter than those in the control group(all P<0.05).The incidence of nausea and vomiting,constipation,pruritus,dizziness and other adverse reactions in the study group was significantly lower than that in the control group(all P<0.05).Conclusion QLB can reduce the fluctuation of intraoperative blood gas indexes in female uremic patients with peritoneal dialysis catheter,relieve postoperative pain,reduce the level of pain factors and reduce the occurrence of adverse reactions,and has a good effect on promoting postoperative recovery of patients.

Objective:This study aimed to analyze the genomic characteristics of Varicella-Zoster Virus (VZV) strains circulating in Jilin province from 2010 to 2023.Methods:Vesicle fluid from 78 sporadic cases with VZV infection were collected in Jilin province from 2010 to 2023, after detecting by Real-time PCR, 26 specimens (CT<25) were detected by PCR. Open reading frame 22(ORF22), ORF38 and ORF62 were amplified and analyzed. Genotyping was confirmed by SNPs ORF22 (37902, 38019, 38055, 38081 and 38177) and ORF38 (69424). Vaccine strains were indentified from wild-type strains according to ORF38 (69349) and ORF62 (106262, 107252, and 108111). Sequences were analyzed by homologous comparison and phylogenetic analysis.Results:The comparison with Dumas sequence revealed that SNPs (37902, 38055, 38081 and 38177) in ORF22 and ORF38 (69424) have mutations similar to the pOka strain, which belong to clade 2. Compared to the Dumas and Baike strains, all 26 samples were wild-type strains. JL2016-4 strain changes from threonine to asparaginyl at position 38059, JL2021-4 strain changes from arginine to proline at position 37933, from aspartic acid to tyrosine at position 37935, and from aspartic acid at base 38031 to tyrosine. JL2023-1 strain changes from arginine to leucine at position 37933.Conclusions:VZV has been prevalent for 14 years in Jilin province. The main epidemic strains belong to the clade 2. We should strengthen the monitoring of VZV outbreaks and raise the coverage rate of VZV vaccination.

Congenital heart disease（CHD）is a common congenital anomaly that is the leading cause of death among children under the age of five years with birth defects in both developed and developing countries. With the increasing prevalence of CHD，the importance of early diagnosis and intervention of CHD is well accepted. Prenatal ultrasonography is routinely applied for the screening of CHD but many factors influence its diagnostic accuracy. Biomarker testing is a simple and rapid method that can be used as an adjunct to prenatal screening for CHD. This review aims to provide new ideas for the early diagnosis of children with CHD by exploring the pathogenesis of biomarkers in CHD. In recent years，many studies have been devoted to the exploration of biomarkers related to CHD，and the studies on biomarkers in CHD are summarized from three aspects：epigenetics，proteomics and environmental factors.

Objective:To investigate the application of ultrasound-guided quadratus lumborum block (QLB) combined with general anesthesia in laparoscopic hysterectomy (LH) and its effect on inflammation and oxidative stress response of patients.Methods:Patients with adenomyosis who underwent surgery to minimize LH in Langfang People’s Hospital from Jan. 2021 to Dec. 2023 were collected as the study subjects. They were divided into two groups according to the random number table method, 53 cases each. The control group were given general anesthesia, and the observation group were given ultrasound-guided QLB+general anesthesia. The recovery and postoperative recovery indexes (recovery, spontaneous breathing recovery, removal of laryngeal mask, first getting out of bed, exhaust time), opioid dosage, remedial analgesia times and first pressing analgesia pump time were counted and compared between the two groups. The pain numerical rating scale (NRS) scores of the two groups at different time points (2, 6, 12, 24 h after operation) were compared. The incidence of adverse reactions during hospitalization was counted and compared between the two groups.Results:The time of awakening, spontaneous breathing recovery, removal of laryngeal mask, first getting out of bed and exhaust in the observation group were shorter than those in the control group ( P < 0.05). The total dosage of remifentanil in the observation group was less than that in the control group, the number of remedial analgesia was lower than that in the control group, and the time of first pressing analgesia pump was longer than that in the control group ( P<0.05). At 6, 12 and 24 h after operation, the NRS scores in resting and active state were higher than those at 2 h after operation. The NRS scores in resting and active state at 24 h after operation were lower than those at 12 h after operation, showing a trend of rising first and then decreasing. The NRS scores in resting and active state in the observation group were lower than those in the control group ( P<0.05). The adverse reaction rate of the two groups was compared ( P> 0.05) . Conclusion:Ultrasound-guided QLB combined with general anesthesia can effectively improve the recovery of LH patients, promote postoperative recovery, relieve postoperative pain, and reduce the dose of opioids.
