Objective:To investigate the effects of laparoscopic transabdominal preperitoneal repair (TAPP) and Lichtenstein surgery on postoperative early pain and mobility in patients with inguinal hernia.Methods:The retrospective cohort study was conducted. The clinical data of 184 pati-ents with unilateral inguinal hernia who were admitted to Shaanxi Provincial People's Hospital from June 2021 to December 2022 were collected. There were 152 males and 32 females, aged (64±8)years. Of the 184 patients, 92 cases undergoing TAPP were divided into the TAPP group, and 92 cases under-going Lichtenstein surgery were divided into the Lichtenstein group. Observation indicators: (1) surgical situations; (2) postoperative pain; (3) postoperative mobility. Comparison of measurement data with normal distribution between groups was conducted using the independent sample t test. Paired sample t test was used for comparison within group before and after surgery. Comparison of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test. Results:(1) Surgical situations. Total duration of hospital stay, duration of postoperative hospital stay, expense of hospitalization were 1.70(1.00,2.00)days, 1.00(1.00,1.00)days, 14 808(14 385,15 292)yuan in the TAPP group, versus 2.12(2.00,3.00)days, 1.42(1.00,2.00)days, 10 590(9802,11 362)yuan in the Lichtenstein group, showing significant differences in the above indicators between the two groups ( Z=-3.23, -4.07, -11.72, P<0.05). (2) Postoperative pain. Score of verbal rating scale (VRS) were 1.36±0.75 and 3.22±0.66 before surgery and at 20-22 hours after surgery in the TAPP group, versus 1.34±0.80 and 3.42±0.80 in the Lichtenstein group, showing significant differences within the two groups ( t=-29.15, -31.46, P<0.05). (3) Postoperative mobility. The time from getting up to standing bedside of patients before surgery and at 20-22 hours after surgery were (5.47±1.08)seconds and (7.94±2.23)seconds in the TAPP group, versus (5.87±1.13)seconds and (11.59±1.88)seconds in the Lichtenstein group, showing a significant difference at 20-22 hours after surgery between the two groups and significant differences within the two groups ( t=-11.99, -15.64, -27.26, P<0.05). The time for hip flexion 90° of patients before surgery and at 20-22 hours after surgery were (0.74±0.32)seconds and (1.23±0.54)seconds in the TAPP group, versus (0.81±0.19)seconds and (1.97±0.69)seconds in the Lichtenstein group, showing a significant difference at 20-22 hours after surgery between the two groups and significant differences within the two groups ( t=-8.11, -16.53, -17.81, P<0.05). The time for walking 10 meters of patients before surgery and at 20-22 hours after surgery were (10.30±1.53)seconds and (12.80±1.67)seconds in the TAPP group, versus (10.38±1.35)seconds and (18.35±1.69)seconds in the Lichtenstein group, showing a significant difference at 20-22 hours after surgery between the two groups and significant differences within the two groups ( t=-22.44, -33.66, -32.46, P<0.05). The time for walking 20 meters of patients before surgery and at 20-22 hours after surgery were (17.87±2.89)seconds and (24.16±2.54)seconds in the TAPP group, versus (18.02±2.82)seconds and (32.64±2.56)seconds in the Lichtenstein group, showing a significant difference at 20-22 hours after surgery between the two groups and significant differences within the two groups ( t=-22.55, -38.75, -34.59, P<0.05). Conclusion:Compared to Lichtenstein surgery, patients with TAPP experience faster recovery of mobility, earlier discharge, and higher expense of hospitalization.

Objective: To investigate the role of long non-coding RNA double homeobox A pseudogene 9 (DUXAP9) in head and neck squamous cell carcinoma (HNSCC) and to evaluate the expression level, molecular function and mechanism of DUXAP9 in HNSCC cells. Methods: Differential expression of lncRNAs between normal and tumor tissues in HNSCC tissues were screened using lncRNA microarray, the expression level of DUXAP9 in HNSCC tissues and its relationship with prognosis were analyzed in the TCGA database. The expression levels of DUXAP9 in HNSCC tissues and cell lines were detected using qRT-PCR. The function in HNSCC cells after DUXAP9 silencing was evaluated using the CCK-8 assay, wound healing assay, Transwell migration assay and subcutaneous xenograft assay in nude mice. Changes in the transcription and translation of epithelial-mesenchymal transition (EMT)-related proteins in head and neck squamous cell carcinoma cells after DUXAP9 silencing were detected using qRT-PCR and Western blot. Results: lncRNA microarray results showed that, compared to adjacent normal tissues, DUXAP9 was abnormally upregulated in HNSCC tissues. Analysis from TCGA database showed that, compared to HNSCC patients with low DUXAP9 expression, HNSCC patients with high DUXAP9 expression had poorer survival. The relative expression of DUXAP9 in HNSCC tissues and 4 HNSCC cell lines increased compared to paired adjacent normal tissues as detected using qRT-PCR. Silencing DUXAP9 significantly inhibited the proliferation, migration and expression of EMT-related genes in HNSCC cells. The silencing of DUXAP9 significantly inhibited subcutaneous tumorigenesis of the HNSCC cell line CAL27 in nude mice. Conclusion Silencing DUXAP9 significantly inhibited the proliferation of HNSCC cells and subcutaneous xenografts in nude mice. DUXAP9 may mediate the migration of head and neck squamous cell carcinoma cells via the EMT pathway.

Objective:To evaluate the therapeutic effect of electroacupuncture on acute gastrointestinal injury (AGI) in patients with severe traumatic brain injury (sTBI).Methods:A prospective randomized controlled trial was conducted. 126 consecutively hospitalized patients with AGI after sTBI admitted to intensive care unit (ICU) of the First Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine from January 2018 to December 2019 were enrolled. The patients were divided into observation group and control group by random number table. All the patients of two groups were given conventional treatment of western medicine for consecutive 7 days, including the treatments of primary diseases, indwelling nasogastric tube to extract gastric contents every 6 hours to determine gastric residual volume (GRV). When vital signs were basically stable, enteral nutrition (EN) was implemented and EN feeding amount and speed were adjusted according to GRV. On the basis of conventional western medicine treatment, the observation group was treated with electroacupuncture at Zusanli, Tianshu, Shangjuxu, Xiajuxu and Zhongwan, once in the morning and once in the evening, 30 minutes each time. The gastrointestinal function parameters including intra-abdominal pressure (IAP), serum diamine oxidase (DAO) and gastrointestinal failure (GIF) scores were observed before treatment and at day 3 and day 7 of treatment. The incidence of ICU hospital-acquired pneumonia (HAP-ICU), duration of mechanical ventilation (MV), length of ICU stay, 28-day mortality and adverse reactions of electroacupuncture were also observed in the two groups. Kaplan-Meier method was used for 28-day survival analysis.Results:During the 7-day treatment and observation, 26 cases of 126 patients withdrew from the study, and 100 cases were actually enrolled, 50 cases in the observation group and 50 cases in the control group. IAP and DAO at day 3 of treatment in both groups were significantly lower than those before treatment [control group: IAP (cmH 2O, 1 cmH 2O = 0.098 kPa) was 13.75±2.76 vs. 18.11±3.97, DAO (U/L) was 129.88±24.81 vs. 158.01±22.64; observation group: IAP (cmH 2O) was 13.56±2.19 vs. 18.50±3.54, DAO (U/L) was 129.11±29.32 vs. 159.36±28.65; all P < 0.01]. The gastrointestinal function parameters of the two groups improved gradually with the extension of treatment time, and the IAP, DAO and GIF scores at day 7 of treatment in the observation group were significantly lower than those in the control group [IAP (cmH 2O): 11.28±3.61 vs. 12.68±3.23, DAO (U/L): 49.69±17.56 vs. 57.27±20.15, GIF score: 2.02±0.74 vs. 2.40±0.70, all P < 0.05). The duration of MV and the length of ICU stay in the observation group were significantly shorter than those in the control group [duration of MV (days): 15.72±4.60 vs. 18.08±4.54, length of ICU stay (days): 16.76±4.68 vs. 19.26±5.42, both P < 0.05], and the incidence of ICU-HAP and 28-day mortality were significantly lowered (12.0% vs. 30.0%, 22.0% vs. 32.0%, both P < 0.05). Survival analysis showed that the 28-day cumulative survival rate in the observation group was significantly higher than that in the control group (86.4% vs. 76.1%; Log-Rank test: χ 2 = 37.954, P < 0.001). The patients in the observation group had no significant adverse reaction of electroacupuncture treatment. Conclusion:Electroacupuncture at corresponding acupoints can effectively improve gastrointestinal function in patients with AGI after sTBI, which is beneficial to shortening the length of ICU stay, promoting the recovery of the patients, and reducing the 28-day mortality.

Objective: To compare the effects of various interventions on the incidence of central line-associated bloodstream infection (CLABSI) . Methods: The clinical data of 218 patients with central venous catheterization were retrospectively analyzed. Infected patients were treated as CLABSI group and non-infected patients as control group. Results: Of the 218 patients, 24 patients were developed CLABSI. There was no significant difference in sex, age, primary infection status and puncture site between CLABSI group and control group. Univariate analysis showed that axillary vein puncture could significantly reduce the incidence of CLABSI (P=0.028), and the infection rate of axillary vein puncture per 1000 days under B-ultrasound was significantly reduced by 0.93‰. The average indwelling days of deep venous catheter in patients with pulse puncture were significantly longer than those in other groups (47.32 days vs 19.90 days). The average indwelling days in patients with axillary vein puncture positioned by B ultrasound were longer than those in patients with other parts of vein puncture positioned by B ultrasound (P < 0.05). Logistic multiple regression analysis showed that the main risk factors for CLABSI were anatomically located puncture (P = 0.031) and non-axillary venous catheterization (P = 0.068). Conclusions Choosing axillary vein as the position of deep venous catheterization and using ultrasound-guided central venous puncture can reduce the incidence of CLABSI and prolong the average catheterization time.
