Objective To compare the clinical efficacy of abdominal ultrasound-guided endoscopic retrograde appendicitis therapy(ERAT)with laparoscopic appendectomy(LA)for acute uncomplicated appendicitis using propensity score matching.Methods The clinical data of 441 patients with acute uncomplicated appendicitis admitted to the Third People's Hospital of Yunnan Province from March 2020 to April 2023 were collected.The cases were classified based on the differences in surgical method and divided into the ERAT group(n = 30)and LA group(n = 411).The clinical efficacy of patients was compared between the two groups after reducing confounding bias by propensity score matching(PSM).Results After PSM,a total of 30 pairs of patients in the two groups were successfully matched,and the baseline data of the two groups met the requirements for comparability.At 24 hours after the operation,the ERAT group exhibited lower white blood cells,neutrophil counts,and C-reactive protein levels compared to the LA group,and these differences were statistically significant(P<0.05).There was no significant difference in the operation time and total effective rate between the ERAT group and the LA group(P>0.05).However,the ERAT group had lower intraoperative blood loss and shorter pain relief time compared to the LA group,and these differences were statistically significant(P<0.05).Conclusion Abdominal ultrasound-guided endoscopic retrograde appendicitis treatment is an effective,safe,and feasible technique with good prospects for the treatment of acute uncomplicated appendicitis.

Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine （TCM） mainly involves peripheral vestibular diseases of Western medicine， such as Meniere's disease， benign paroxysmal positional vertigo， vestibular neuritis， and vestibular migraine， being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo， aural vertigo affecting the quality of life， aural vertigo not relieved after surgery， aural vertigo with complex causes， and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM： Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo， the control and mitigation of the symptoms， and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.

Objective To investigate the clinical application value of transrectal real-time tissue elastography(TRTE)guided targeted puncture in the diagnosis of prostate cancer.Methods A total of 52 patients with suspected prostate cancer who were treated in the First People's Hospital of Zhengzhou from January 2020 to December 2022 were selected as the study objects.Preoperative routine transrectal ultrasound and TRTE examination were performed to evaluate the benign and malignant prostates.For the 28 patients with suspected lesions found in TRTE,TRTE-guided targeted puncture(2 needles)+ systematic puncture(8 needles)were performed,for the 24 patients with no suspicious lesions found in TRTE,routine ultrasound-guided systematic puncture(12 needles)was performed.The efficacy of TRTE in the diagnosis of prostate cancer was analyzed and the positive rate of targeted puncture and systematic puncture was compared.Results In this study,25 cases of prostate cancer and 27 cases of benign lesions were ultimately pathologically diagnosed,while a total of 28 cases of prostate cancer and 24 cases of benign lesions were diagnosed with TRTE.The positive predictive value and negative predictive value of the diagnosis were 75.0%(21/28)and 83.3%(20/24),respectively.In 28 patients with suspected lesions found by TRTE,a total of 56 needles were targeted puncture,36 needles were diagnosed with prostate cancer,positive rate was 64.29%(36/56),and a total of 224 needles were systematic puncture,89 needles were diagnosed with prostate cancer,with a positive rate of 39.73%(89/224).The positive rate of prostate cancer by targeted puncture was significantly higher than that by systematic puncture(P<0.05).Conclusion TRTE can better diagnose prostate cancer,and its guided targeted puncture has a higher positive rate in the diagnosis of prostate cancer,which can maximize the positive rate of puncture while reducing the number of puncture needles.

OBJECTIVE To investigate the transfer and diffusion of berberine hydrochloride(BBH), the main active component of Coptis and Phellodenticum in the system of carboxymethyl chitosan(CMCS)-sodium alginate(SA). METHODS CMCS and SA were stirred in a certain proportion, and D-gluconolactone(GDL) was added to form polyelectrolyte hydrogel. Rheometer was used to study the rheological properties of CMCS-SA hydrogel, including the elastic modulus G′ and the viscous modulus G′′. A BBH diffusion model for CMCS-SA hydrogel was designed, and the relevant rules of BBH permeation through CMCS-SA polyelectrolyte hydrogel were observed by UV-VIS. RESULTS The elastic modulus G′ of the hydrogel was measured when the ratio of CMCS to SA was 3∶1, 2∶1, 1∶1, 1∶2, and 1∶3. When the ratio of CMCS to SA was 1∶1, G′ was the highest, and the crosslinking strength of the hydrogel was the highest. The cumulative amount of BBH transfer was measured by the BBH transfer model, and the diffusion of BBH in CMCS-SA hydrogel was fitted as the skeleton dissolution by Peppas equation, indicating that BBH dissociation and the transfer efficiency increased as the amino group of CMCS decreased or the carboxyl group of SA increased. The elastic modulus G′ of CMCS-SA hydrogel increased with the increase of GDL content. The reason was that the binding force between CMCS and SA molecules gradually increased with the decrease of pH, and the crosslinking degree of the hydrogel was enhanced. When ratio of fixed CMCS to SA was 1∶1 and the GDL content was 0.15 g·mL−1, the formability of CMCS-SA hydrogel was good. In addition, when BBH was transferred in hydrogel with different concentrations of GDL, the transfer efficiency increased with the increase of GDL content. When BBH was delivered in different thickness hydrogel, the delivery efficiency of CMCS-SA hydrogel increased with the decrease of thickness. CONCLUSION The CMCS-SA hydrogel system, as a potential drug carrier for traditional Chinese medicine extracts such as BBH, is expected to serve as a gel carrier for transdermal drug delivery.

BACKGROUND: Xuanwei and Fuyuan are rural counties, located in the late Permian coal poly area of eastern Yunnan and western Guizhou, where lung cancer mortality rates are among the highest in the China, with similarity for both men and women, younger age at diagnosis and death, and higher in rural areas than in urban areas. In this paper, long-term follow-up of lung cancer cases in local peasants was conducted to observe their survival prognosis and its influencing factors. METHODS: Data of patients diagnosed with lung cancer from January 2005 to June 2011, who had lived in Xuanwei and Fuyuan counties for many years, were collected from 20 hospitals at the local provincial, municipal and county levels. To estimate survival outcomes, individuals were followed up until the end of 2021. The 5-year, 10-year and 15-year survival rates were estimated using the Kaplan-Meier method. Survival differences were examined with Kaplan-Meier curves and Cox proportional hazards models. RESULTS: A total of 3,017 cases were effectively followed up (2,537 peasants and 480 non-peasants). The median age at diagnosis was 57 years, and the median follow-up time was 122 months. During the follow-up period, 2,493 cases (82.6%) died. The distribution of cases by clinical stage was as follows: stage I (3.7%), stage II (6.7%), stage III (15.8%), stage IV (21.1%) and unknown stage (52.7%). Treatment at the provincial, municipal and county-level hospitals accounted for 32.5%, 22.2% and 45.3%, respectively, and surgical treatment was performed in 23.3% of cases. The median survival time was 15.4 months (95%CI: 13.9-16.1), and the 5-year, 10-year and 15-year overall survival rates were 19.5% (95%CI: 18.0%-21.1%), 7.7% (95%CI: 6.5%-8.8%) and 2.0% (95%CI: 0.8%-3.9%), respectively. Peasants with lung cancer had a lower median age at diagnosis, higher proportion residing in remote rural areas, and higher use of bituminous coal as a household fuel. They also have a lower proportion of early-stage cases, treatment at provincial or municipal hospitals, and surgical treatment, leading to poorer survival outcomes (HR=1.57). Even when considering factors such as gender, age, residential location, clinical stage at diagnosis, histological type, hospital level of service, and surgical intervention, peasants still exhibit a survival disadvantage. Multivariable Cox model analysis comparing peasants and non-peasants reveals that surgical intervention, tumor-node-metastasis (TNM) stage, and hospital level of service are common factors influencing survival prognosis, while the use of bituminous coal as a household fuel, hospital level of service and adenocarcinoma (compared to squamous cell carcinoma) are independent prognostic factors for lung cancer survival among peasants. CONCLUSIONS The lower lung cancer survival rate among peasants is associated with their lower socioeconomic status, lower proportion of early-stage diagnoses, lower proportion of surgical interventions, and treatment at provincial-level hospitals. Furthermore, the impact of other factors such as high-risk exposure to bituminous coal pollution on survival prognosis requires further investigation.

Objective:To study the clinical characteristics of neonatal umbilical vascular catheter (UVC) rupture.Methods:A neonate with UVC rupture admitted to Neonatology Department of our hospital was retrospectively reviewed. Literature on this subject were searched in the following databases: Chinese Medical Journal full-text Database, CNKI, Wanfang Database, CQVIP database, PubMed, Web of Science, Embase and Cochrane Library (up until March 15 2022). The causes, treatment and prognosis of neonatal UVC rupture were analyzed.Results:In our case, the UVC was accidentally damaged during the removal of the ligature suture. The UVC was ruptured after a slight force was applied to remove the catheter, resulting in approximately 7 cm of UVC remaining in the body. Trans-umbilical vein intervention was performed and the catheter was successfully removed with a lasso under X-ray guidance. A total of 33 UVC rupture cases were included from 15 articles (no case report in China before). In 16 cases (47.1%), the UVCs were accidentally cut off by knife or scissors when removing the catheter. In 3 cases (8.8%), the UVCs were broken during insertion. The UVC was broken in 1 case (2.9%) during flushing the catheter. The causes of the other 14 cases (41.2%) were unknown. 9 cases (26.5%) had clinical manifestations, including respiratory distress, prominent heart murmur, sepsis and limb ischemia. 20 cases (58.8%) showed no clinical features. No data on the other 5 cases (14.7%). 21 cases (61.8%) received vascular intervention removal, 11 cases (32.4%) received surgical removal, 1 case (2.9%) was removed with tweezers, and 1 case (2.9%) died before UVC was removed. Among the neonates receiving surgical treatment, 1 case died of sepsis on the second day after surgery and 1 case had sequela of limb ischemia. 2 cases had postoperative vasospasm and embolism after vascular intervention with overall good prognosis.Conclusions:The rupture of UVC in neonates is rare and mainly related with knife and scissors injury.

Objective:To investigate the clinical manifestations of population following COVID-19 by using questionnaires.Methods:COVID-19 among anesthesia workers and the surrounding population was investigated between 11 November 2022 and 31 December 2022 in China.The Tencent electronic questionnaire(ID.11492813) was sent to different WeChat groups of the Association of Anesthesiologists or Society of Anesthesiologists via the WeChat platform of the medical personnel in China. The survey was conducted between January 7 and January 15, 2023. Results:A total of 17 000 questionnaires were issued for this survey, 11 060 valid questionnaires from 31 provinces and autonomous regions were collected all over the country, with a recovery rate of 65.059%.There were 10068 (91.037%) participants diagnosed as having COVID-19, and among of them, 47.606% were male and 52.394% were female. The main post-COVID-19 clinical manifestations included fever (85.777%), cough (83.731%), fatigue (75.338%), parasomnia (64.352%), limb soreness (58.890%), dizziness, headache, tinnitus (38.617%), loss or abnormality of taste (37.763%), and loss or abnormality of smell (30.960%); peripheral neuralgia was usually found within 3 days after positive nucleic acid test or positive antigen test; there were 2 963 cases accompanied with sweating, and among of them, 47.25% were male and 52.75% were female, and 37.80% of these participants continued to sweat after the nucleic acid test or antigen test became negative. There were 1 151 cases with premature heart beats among the study population, and the symptoms aggravated following COVID-19 were found in 34.32% of these patients.Conclusions:In addition to the respiratory system, the central and peripheral nerves of patients are also affected following COVID-19, and the peripheral and central nerve disorders last until several days after negative nucleic acid test or antigen test, suggesting that anesthesiologists should pay more attention to monitoring of various nerve function and impact of surgery and anesthetic drugs on the stress response of the body in such patients.

Objective:To investigate the effects of breast milk to total milk intake ratio during hospitalization on the duration of antibiotic therapy in preterm infants less than 34 weeks of gestation.Methods:Clinical data of preterm infants ( n=1 792) less than 34 gestational weeks were retrospectively collected in 16 hospitals of Jiangsu Province Neonatal-Perinatal Cooperation Network from January 1, 2019, to December 31, 2021. The days of therapy (DOT) were used to evaluate the duration of antibiotic administration. The median DOT was 15.0 d (7.0-27.0 d). The patients were divided into four groups based on the quartiles of DOT: Q 1 (DOT≤7.0 d), Q 2 (7.0 d27.0 d) groups. According to the breast milk intake ratio (breast milk intake to total milk intake during hospitalization×100%), they were also divided into four groups: very-low-ratio breastfeeding group (breast milk intake ratio≤25%), low-ratio breastfeeding group (25%75%). Univariate analysis ( Chi-square test and Kruskal-Wallis rank-sum test) was used to analyze the factors influencing DOT. Spearman correlation analysis and trend Chi-square test were used to explore the relationship between breast milk intake ratio and DOT. After using multiple imputations to address missing data, two models were constructed after adjusting for different factors, and multinomial logistic regression model was applied to evaluate the effects of the breast milk intake ratio on DOT. Finally, sensitivity analysis was conducted to assess the stability of the models. Results:(1) Of the 1 792 preterm infants, there were 507 (28.3%) in the Q 1 group, 422 (23.5%) in the Q 2 group, 438 (24.4%) in the Q 3 group and 425 (23.7%) in the Q 4 group. (2) The median values of DOT in the very-low-ratio, low-ratio, medium-ratio and high-ratio breastfeeding groups were 20.0 d (11.0-31.0 d), 20.0 d (11.0-32.0 d), 13.0 d (6.0-25.8 d) and 10.0 d (4.0-21.0 d), respectively. Compared with the very-low-ratio and low-ratio breastfeeding groups, the medium-ratio and high-ratio breastfeeding groups had shorter DOT (all P<0.05). (3) After adjusting for factors with P<0.1 (prenatal glucocorticoid exposure, antimicrobial use within 24 h before delivery, gestational age at delivery, birth weight, Apgar score≤7 at 1 min, neonatal respiratory distress syndrome, infectious pneumonia and early-onset neonatal sepsis) between the DOT quartile groups, it showed that medium-ratio and high-ratio breastfeeding were protective factors in contrast to very-low-ratio breastfeeding in the Q 2, Q 3 and Q 4 groups as compared with the Q 1 group [Q 2 group: OR=0.50 (95% CI: 0.30-0.85) and OR=0.36 (95% CI: 0.26-0.51); Q 3 group: OR=0.31 (95% CI: 0.18-0.55) and OR=0.20 (95% CI: 0.14-0.29); Q 4 group: OR=0.22 (95% CI: 0.12-0.42) and OR=0.17 (95% CI: 0.12-0.26)]. Conclusion:Breast milk intake accounting for over 50% of total milk intake has a positive impact on reducing DOT in premature infants requiring antibiotics, which suggests that breastfeeding should be actively encouraged.
