Background:
and Purpose Ruptured intracranial aneurysms (RIA) are associated with a mortality rate of up to 40% in the Chinese population, highlighting the critical need for targeted treatment interventions for at-risk individuals. Although the impact of aldehyde dehydrogenase 2 (ALDH2) gene mutations on susceptibility to intracranial aneurysms (IA) is well documented, the potential connection between ALDH2 rs671 single-nucleotide polymorphism (SNP) and RIA remains unexplored. Given the increased prevalence of ALDH2 gene mutations among Chinese Han individuals, it is clinically relevant to investigate the link between ALDH2 rs671 SNP and IA rupture.
Methods:
A prospective study was conducted on 546 patients diagnosed with IA to investigate the association between ALDH2 rs671 SNP and the risk of IA rupture.
Results:
The ALDH2 rs671 SNP (ALDH2*2) was significantly more prevalent in patients with unruptured IA (UIA) than in those with RIA (32.56% vs. 18.58%, P=0.004). Multivariate logistic regression analysis revealed that people with the ALDH2 mutation (ALDH2*1/*2 and ALDH2*2/*2 gene type) had a significantly reduced odds ratio (OR=0.49; 95% confidence level [CI] 0.27–0.88; P=0.018) for RIAs. Age-specific subgroup analysis indicated that the ALDH2 mutation provided a stronger protective effect in individuals aged 60 years and above with IA compared to those under 60 years old (OR=0.38 vs. OR=0.52, both P<0.05).
Conclusion
The incidence of RIA was significantly higher in individuals with a normal ALDH2 gene (ALDH2*1/*1) than in those with an ALDH2 rs671 SNP (ALDH2*1/*2 or ALDH2*2/*2). ALDH2 rs671 SNP may serve as a protective factor against RIA in the Chinese Han population.

Metastasis is crucial for the mortality of non-small cell lung carcinoma (NSCLC) patients. The epithelial-mesenchymal transition (EMT) plays a critical role in regulating tumor metastasis. Glioma-associated oncogene 1 (Gli1) is aberrantly active in a series of tumor tissues. However, the molecular regulatory relationships between Gli1 and NSCLC metastasis have not yet been identified. Herein, we reported Gli1 promoted NSCLC metastasis. High Gli1 expression was associated with poor survival of NSCLC patients. Ectopic expression of Gli1 in low metastatic A549 and NCI-H460 cells enhanced their migration, invasion abilities and facilitated EMT process, whereas knock-down of Gli1 in high metastatic NCI-H1299 and NCI-H1703 cells showed an opposite effect. Notably, Gli1 overexpression accelerated the lung and liver metastasis of NSCLC in the intravenously injected metastasis model. Further research showed that Gli1 positively regulated Snail expression by binding to its promoter and enhancing its protein stability, thereby facilitating the migration, invasion and EMT of NSCLC. In addition, administration of GANT-61, a Gli1 inhibitor, obviously suppressed the metastasis of NSCLC. Collectively, our study reveals that Gli1 is a critical regulator for NSCLC metastasis and suggests that targeting Gli1 is a prospective therapy strategy for metastatic NSCLC.

Objective:To explore the effect of occupational nickel exposure on blood glucose related indicators of workers.Methods:In March 2019, five electroplating enterprises and one plastic hardware enterprise were selected by cluster sampling method. 159 nickel plating workers were selected as the contact group, and 66 administrative personnel of the same enterprise were selected as the control group. The serum nickel concentration, fasting blood glucose (FPG) , fasting insulin (FIns) and glycosylated hemoglobin (HbA1c) were measured in the contact group and the control group. The differences of blood glucose related indexes between the two groups were compared, and the risk factors of abnormal blood glucose indexes were analyzed.Results:Compared with the control group, the blood nickel concentration and detection rate of nickel in the contact group were higher, the levels of FIns were lower, and the proportion of HbA1c was higher in the contact group ( P<0.05) . Stratified analysis showed that compared with the control group, the blood glucose index of men in the contact group changed significantly ( P<0.05) ; logistic regression analysis showed that male was an independent influencing factor for decreased FIns ( OR=8.264, P<0.05) . Conclusion:Long term exposure to nickel can affect the blood glucose related indexes such as fins and HbA1c.

Aim To clarify the effect of Borneol on the chloride channels and cell volume in poorly differentia-ted nasopharyngeal carcinoma CNE-2Z cells.Methods The technique of whole-cell patch clamp was used to detect the chloride currents and analyze the character-istics of the currents in CNE-2Z cells.The volume changes caused by Borneol were measured by the meth-od of time-lapse live cell imaging.Results The chlo-ride currents were induced by extracellular application of Borneol (20 μmol·L -1 )isotonic condition.The currents showed a characteristic of outward rectification and did not show voltage-dependent or time-dependent inactivation.The reversal potential of the currents was close to the CI-equilibrium potential. The currents were inhibited by the chloride channel blocker tamox-ifen.The currents were also inhibited by 47% hyper-tonic solution.Borneol decreased the cell volume by 9.4% in 30 min.Tamoxifen completely inhibited the Borneol-induced cell volume decrease.Conclusion Borneol can activate volume-sensitive chloride channels and induce volume decrease in CNE-2Z cells.Chloride channels play a pivotal role in the process of volume decrease caused by Borneol.

Objective To evaluate the technique and clinical outcomes of modified transperitoneal laparoscopic radical prostatectomy. Methods A total of 285 patients received the operation with mean age of 67 years (50-76 years) from January 2008 to April 2012.Mean level of PSA was 15.7 μg/L (1.8 -50.0 μg/L),and mean prostatic volume was 44 ml (26 -74 ml). No lymph node or seminal vesicle involvement was found by CT or MR and radionuclide bone scan revealed no metastasis.271 cases were confirmed diagnosis by prostatic biopsy and 14 were detected through pathological studies of TURP specimens.Gleason score ranged from 6 to 8.14 cases were in clinical stage T1b,29 cases in T1c,214 cases in T2 and 28 cases in T3a.Transperitoneal approach and modified technique involving bladder neck dissection,nervesparing technique and vesicoureteral anastomosis were applied on patients. Results Mean operative time was 105 min (55 -150 min).Mean intraoperative estimated blood loss was 240 ml (50-800 ml).Rectal injures occurred in 2 cases and were repaired under laparoscopy.Drainage tube and urinary catheter were removed 48 -72 h and 5 -8 d postoperatively.Postoperative hospital stay was 7 d (5 - 11 d).Positive surgical margin was present in 58 patients.Mean follow-up time was 29 months (3 -50 months).Complete continence were found in 208 patients immediately after catheter removal.68 patient recovered continence within 3 months and 9 patients remained incontinence 3 months after surgery. Normal erection presented in 42 of the 57 cases with nerve-sparing. Conclusions Transperitoneal laparoscopic radical prostatectomy is safe and efficient.Higher efficiency and lower complication rate have been achieved through modified laparoscopic technique involving bladder neck dissection,nerve-sparing technique and vesicoureteral anastomosis.

Objective To summarize the experience of intraoperative neuromonitoring (IONM) system for monitoring and protection of recurrent laryngeal nerve (RLN) during thyroid surgery.Methods A total of 220 cases were enrolled in this study (53 males and 167 females),with the median age of 38.2 years old.There were 85 cases of thyroid cancer,19 cases of thyroid benign tumor,90 cases of thyroid goiter,3 cases of Hashimoto's diseases,and 23 cases of hyperthyroidism.113 cases had tumors larger than 5 cm in diameter.During the procedure,2 recording needle electrodes were put in cricothyroid muscle and 1 stimulator electrode was explored in tracheoasophageal groove.If any RLN was fight there or nearby,doctors can see the electromyogram and hear the toothonk.With careful dissection,RLN can be found out till exploring into the larynx site.Results Electromyogram showed in 207 cases (278 nerves),and it didn't show in 13 cases,among whom 9 cases were false-negative because of system or annesthesia problems,4 cases didn't manage to have needle electrodes put in properly due to cricothyroid muscle being invaded.No permanent RLN paralysis occoured.Transient nerve paralysis occurred in 2 cases,who recovered in 1 month after operation.Conclusion IONM system is an effective way to avoid damage to RLN in thyroidectomy.
