Objective:To investigate the correlation and causal relationship between neonatal birth weight and urinary microproteins and creatinine in adulthood.Methods:Genome-wide association studies were conducted to extract genetic loci with significant influ-ence from dataset as instrumental variables,and they were analyzed by inverse variance weighted(IVW),weighted median,MR Egger,and MR-PRESSO methods to investigate the causal relationship between neonatal birth weight and urinary microproteins and creati-nine in adulthood.A retrospective analysis was performed for 113 neonates who were admitted to Department of Neonatology,Shanxi Children's Hospital,from January 2005 to January 2007,and related data were collected during the neonatal and adult stages.A Pear-son correlation analysis was used to determine the correlation between neonatal birth weight and urinary microproteins and creatinine in adulthood.Results:The MR-IVW test showed that neonatal birth weight had a statistically significant correlation with urinary micro-proteins(P=0.037)and urinary creatinine(P=0.015)in adulthood.The retrospective study showed that there were no significant differ-ences between the two groups in all variables except body weight(P>0.05).In addition,the Pearson correlation analysis showed that neonatal birth weight was negatively correlated with urinary microproteins(r=-0.78,P=0.015)and was positively correlated with uri-nary creatinine(r=0.78,P=0.018).Conclusion:Neonatal birth weight is negatively correlated with urinary microproteins and is positively correlated with urinary creatinine in adulthood.

OBJECTIVE To preliminarily assess the horizontal sound localization and its influencing factors in patients with unilateral sudden sensorineural hearing loss during the acute phase.METHODS The azimuth discrimination test and azimuth identification test were completed,with the speech sound(65 dB SPL)as the stimulus.The minimum audible angle(MAA)and root-mean-square error(RMSE)were obtained,and the RMSE of the affected side and the healthy side were calculated respectively.According to the WHO(2021)hearing loss classification criteria,the data were analyzed based on the pure-tone average(PTA)of the affected ear.And the best resident hearing at each frequency of the affected ear was recorded.RESULTS The performance of the unilateral sudden sensorineural hearing loss patients in the sound localization varied greatly.Some performed close to the normal level,while others completely lost the ability to localize sound.The RMSE of the moderate hearing loss group(≥35 dB HL)was significantly higher than that of the normal hearing group(P<0.01),the MAA of the moderate to severe hearing loss group(≥50 dB HL)showed statistically significant differencescompared with normal hearing group(P<0.001).The RMSE of the affected side of patients in the severe and above hearing loss group was significantly larger than that of the healthy side.Regression analysis showed that the best resident hearing at each frequency of the affected ear was the most significant factor affecting MAA(R2=0.572,P<0.001)and RMSE(R2=0.768,P<0.001).CONCLUSION The horizontal sound localization of unilateral sudden sensorineural hearing loss patients in the acute phase varies greatly.When the PTA of the affected side reaches moderate hearing loss,the localization ability is significantly lower than that of normal-hearing individuals.The best resident hearing at each frequency of the affected ear is the key factor affecting the localization ability.

Objective To evaluate the effect of ultrasound-guided selective brachial plexus block on postoperative muscle strength in the block area of patients after wrist surgery.Methods Sixty patients who underwent wrist surgery,33 males and 27 females,aged 18-64 years,BMI 21-28 kg/m2,ASA physi-cal status Ⅰ or Ⅱ,were randomly divided into two groups by random number table method:ultrasound guided selective brachial plexus block in the middle of the forearm group(group A)and ultrasound guided axillary brachial plexus block group(group B),30 patients in each group.In group A,the ulnar nerve,and/or median nerve,and/or radial nerve were selectively blocked in the middle of the forearm according to the location of the surgical incision,and 0.4％ropivacaine was injected into each nerve with 5 ml.Patients in group B received conventional axillary brachial plexus block under ultrasound guidance and injected 30 ml of 0.4％ropivacaine.In the both two groups,dexmedetomidine 0.8 μg/kg was injected for 10 minutes be-fore nerve block,and was changed to 0.4 μg·kg-1·h-1 until the end of operation,and then patients were transferred to the recovery room for observation 30 minutes and then returned to the ward.Muscle strength 2,4,8,12,24,48 hours after operation and recovery time to grade 5 were recorded.VAS pain scores at rest and exercise 2,4,8,12,24,and 48 hours after surgery and tourniquet tolerance scores were recorded.Satisfaction score,nerve block operation time,anesthesia onset time,duration of analgesia,number of addi-tional postoperative analgesics,occurrence of postoperative remedial analgesia,and length of hospital stay were recorded.Complications such as hematoma,nerve injury and infection were recorded.Results Com-pared with group B,the muscle strength score of patients in group A 2,4,8 and 12 hours after surgery was significantly higher(P＜0.05),the time of muscle strength recovery to level 5 in group A was significantly shorter(P＜0.05).Compared with group B,the satisfaction score in group A was better(P＜0.05),the duration of nerve block operation and hospitalization in group A was shorter(P＜0.05),the intraoperative tourniquet tolerance score of in group A was worse(P＜0.05),and both groups were tolerated.There were no significant differences in VAS pain scores at rest and exercise,the onset time of anesthesia,duration of analgesia,number of postoperative analgesia remedies between the two groups.There were no complications such as hematoma,nerve injury and infection in the two groups.Conclusion Ultrasound-guided selective brachial plexus block has little effect on the motor function of upper arm and forearm,and muscle strength recovers quickly after operation,can be safely and effectively adopted in short wrist surgery.

Objective:To investigate the influence of curative-intent resection with textbook outcomes of liver surgery (TOLS) on long-term prognosis of gallbladder carcinoma (GBC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 824 patients with GBC in the national multicenter database of Biliary Surgery Group of Elite Group of Chinese Journal of Digestive Surgery, who were admitted to 15 medical centers from January 2014 to January 2021, were collected. There were 285 males and 539 females, aged (62±11)years. According to the evalua-tion criteria of TOLS, patients were divided into those who achieved TOLS and those who did not achieve TOLS. Measurement data with normal distribution were represented as Mean± SD, and com-parison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data were conduc-ted using the Mann-Whitney U test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and the Log-rank test was used for survival analysis. The COX stepwise regression model with backward Wald method was used for univariate and multivariate analyses. Results:(1) Achievement of TOLS. Of the 824 patients undergoing curative-intent resection for GBC, there were 510 cases achieving TOLS and 314 cases not achieving TOLS. (2) Follow-up. Of the 824 patients undergoing curative-intent resection for GBC, after excluding 112 deaths within 90 days after discharge, 712 cases were included for the survival analysis. The median follow-up time, median overall survival time and 5-year overall survival rate of the 510 patients achieving TOLS were 22.1(11.4,30.1)months, 47.6(30.6,64.6)months and 47.5%. The median follow-up time, median overall survival time and 5-year overall survival rate of the 202 patients not achieving TOLS were 14.0(6.8,25.5)months, 24.3(20.0,28.6)months and 21.0%. There was a significant difference in overall survival between patients achieving TOLS and patients not achieving TOLS ( χ2=58.491, P<0.05). (3) Analysis of factors influencing prognosis of patients. Results of multivariate analysis showed that TOLS, carcinoembryonic antigen (CEA), CA19-9, poorly differentiation of tumor, T2 stage of eighth edition of American Joint Committee on Cancer (AJCC) staging, T3 and T4 stage of eighth edition of AJCC staging, N1 stage of the eighth edition of AJCC staging, N2 stage of the eighth edition of AJCC staging, adjuvant therapy were independent factors influencing overall survival time of patients undergoing curative-intent resection for GBC ( hazard ratio=0.452, 1.479, 1.373, 1.612, 1.455, 1.481, 1.835, 1.978, 0.538, 95% c onfidence interval as 0.352-0.581, 1.141-1.964, 1.052-1.791, 1.259-2.063, 1.102-1.920, 1.022-2.147, 1.380-2.441, 1.342-2.915, 0.382-0.758, P<0.05). Conclusion:Patients under-going curative-intent resection for GBC with TOLS can achieve better long-term prognosis.

Purpose: To evaluate the incidence and identify the risk factors for radiotherapy-induced oral mucositis among patients with nasopharyngeal carcinoma. Methods: A meta-analysis was conducted. Eight electronic databases (Medline, Embase, Cochrane Library, CINAHL Plus with Full Text, Web of Science, China National Knowledge Infrastructure, Wanfang Database, and Chinese Scientific Journals Database) were systematically searched from inception to 4 March 2023 for relevant studies. Study selection and data extraction were conducted by two independent authors. The Newcastle‒Ottawa scale was used for quality assessment among the included studies. Data synthesis and analyses were performed in R software package version 4.1.3 and Review Manager Software 5.4. The pooled incidence was calculated using proportions with 95% confidence intervals (CIs), and the risk factors were evaluated using the odds ratio (OR) with 95% CIs. Sensitivity analysis and predesigned subgroup analyses were also conducted. Results: A total of 22 studies published from 2005 to 2023 were included. The results of the meta-analysis showed that the incidence of radiotherapy-induced oral mucositis was 99.0% among nasopharyngeal carcinoma patients, and the incidence of severe radiotherapy-induced oral mucositis was 52.0%. Poor oral hygiene, overweight before radiotherapy, oral pH < 7.0, the use of oral mucosal protective agents, smoking, drinking, combined chemotherapy, and the use of antibiotics at early treatment stage are risk factors for severe radiotherapy-induced oral mucositis. Sensitivity analysis and subgroup analyses also revealed that our results are stable and reliable. Conclusions Almost all patients with nasopharyngeal carcinoma have suffered from radiotherapy-induced oral mucositis, and more than half of patients have experienced severe oral mucositis. Facilitating oral health might be the key focus of reducing the incidence and severity of radiotherapy-induced oral mucositis among nasopharyngeal carcinoma patients.Registration numberCRD42022322035.

OBJECTIVE: To summarize the regulatory effect of non-coding RNA (ncRNA) on type H vessels angiogenesis of bone. METHODS: Recent domestic and foreign related literature about the regulation of ncRNA in type H vessels angiogenesis was widely reviewed and summarized. RESULTS: Type H vessels is a special subtype of bone vessels with the ability to couple bone formation. At present, the research on ncRNA regulating type H vessels angiogenesis in bone diseases mainly focuses on microRNA, long ncRNA, and small interfering RNA, which can affect the expressions of hypoxia inducible factor 1α, platelet derived growth factor BB, slit guidance ligand 3, and other factors through their own unique ways of action, thus regulating type H vessels angiogenesis and participating in the occurrence and development of bone diseases. CONCLUSION At present, the mechanism of ncRNA regulating bone type H vessels angiogenesis has been preliminarily explored. With the deepening of research, ncRNA is expected to be a new target for the diagnosis and treatment of vascular related bone diseases.
