Objective To compare the clinical effects between uniportal video-assisted thoracic surgery (VATS) and 3-portal VATS lobectomy for patients with lung cancer. Methods Patients were divided into uniportal VATS lobectomy group (n=45) and 3-portal VATS lobectomy group (n=53). The clinical data were compared between two groups, including the oper-ation time, intraoperative blood loss, number of lymph node dissection, length of incision, postoperative extubation time, post-operative pain score and postoperative hospitalization. Results There were no significant differences in intraoperative blood lose (128.75±18.32) mL vs (129.15±17.69) mL, lymph node dissection number (13.33±1.05) vs (13.12±1.38), duration of chest drainage (4.90±0.75)d vs (4.75±0.70)d, duration of hospital stay (7.52±1.16)d vs (7.55±1.10)d and incidence of seri-ous postoperative complications between two groups (P>0.05). The incision length (5.36±0.22)cm vs (7.44±0.35)cm, numeric pain intensity scale including first day(6.47±0.54) vs (6.86±0.52),third day(3.59±0.29) vs (4.05±0.25), and patient satisfac-tion scores (91.03 ± 2.62) vs (88.35 ± 2.97) were significantly better in uniportal VATS group than those of 3-portal VATS group (P<0.05). The operation time (143.81±17.97) min vs(130.11±15.03)min was longer in uniportal VATS group than that of 3-portal VATS group (P < 0.05). Conclusion Uniportal VATS lobectomy is safe and reliable for patients with early-stage lung cancer, which has less surgical injury, slighter pain, and higher satisfaction than 3-portal VATS lobectomy.

Sichuan Mental Health 2023;36(4):377-379
This article presents a case report of Wernicke's encephalopathy misdiagnosed as schizophrenia. The patient was hospitalized and diagnosed with schizophrenia at a local psychiatric hospital over a month ago. Twelve days ago, the patient gradually developed symptoms such as salivation, difficulty in eating, trembling hands, unsteady walking, glossoptosis and so on. The above symptoms were interpreted as drug-induced adverse reactions and managed accordingly, whereas the patient showed a poor response to treatment, and began to experience intermittent consciousness disorder. After referral to our hospital, findings were diagnostic for Wernicke's encephalopathy and peripheral polyneuropathy. Due to the progression of the disease, the family members abandoned further treatment and requested discharge from the hospital, and the patient died outside the hospital. This case report aims to improve the prognosis of Wernicke's encephalopathy in patients with mental disorder by raising the awareness of the disease and enhancing the early prevention.

Objective:To investigate the effect of BMAL1 gene on the proliferation, migration and invasion ability of radiation-resistant nasopharyngeal carcinoma cell line (5-8FR) and the molecular mechanism. Methods:A multi-target click model was constructed for radiation-resistant nasopharyngeal carcinoma cell line 5-8FR by low-dose fractionated irradiation, and the results of clone formation assay were used to fit the multi-target click model and calculate the sensitization ratio of radiotherapy. The expression levels of PI3K/Akt/MMP-2/9 signaling pathway-related proteins in 5-8FR and control 5-8F cell lines were detected by Western blot. The overexpression and knockdown vectors of BMAL1 gene were constructed and transfected with 5-8F and 5-8F cell lines, respectively. The BMAL1 gene overexpression (pcDNA-BMAL1) and its control (pcDNA) and interference (BMAL1-shRNA) and control (con-shRNA) cell lines were stably transfected with nasopharyngeal carcinoma cell line 5-8F and radiation-resistant cell line 5-8FR, respectively. Western blot was performed to verify the infection efficiency and detect the changes of PI3K/Akt/MMP-2/9 signaling pathway-related proteins after overexpression or interference of BMAL1 gene in both groups of cells. CCK-8 assay, cell scratch test and Transwell chamber test were conducted to investigate the proliferation, migration and invasion capabilities of 5-8FR cell line after overexpression or interference of BMAL1 gene. Results:BMAL1 gene expression was down-regulated, and those of PI3K/Akt pathway proteins and downstream related molecules of MMP-2 and MMP-9 were up-regulated, and TIMP-2 and TIMP-1 expression was down-regulated in nasopharyngeal carcinoma radiation-resistant cell lines. Overexpression of BMAL1 gene inhibited the expression of PI3K/Akt pathway proteins and downstream related molecules of MMP-2 and MMP-9, promoted the expression of TIMP-2 and TIMP-1, and inhibited the proliferation, migration and invasion capabilities of radiation-resistant nasopharyngeal carcinoma cells, while interference with BMAL1 gene yielded the opposite results. Conclusions:BMAL1 gene can reverse the expression of PI3K/Akt/MMP-2/9 signaling pathway-related proteins in radiation-resistant nasopharyngeal carcinoma cell lines and inhibit the proliferation, migration and invasion capabilities of radiation-resistant nasopharyngeal carcinoma cell lines.

Objective:To analyze the characteristics of etiology and clinical indicators of hepatitis B virus (HBV) and non-HBV liver failure, and to evaluate their potential roles in reflecting disease outcomes.Methods:The clinical data of 369 patients with liver failure admitted to the intensive care unit (ICU) of the Fifth People's Hospital of Wuxi which was the designated hospital for treatment of liver failure from January 2018 to December 2020 were retrospectively analyzed. The classification and comparison of etiology of non-HBV and HBV liver failure patients were performed according to the Guidelines on the Diagnosis and Treatment of Liver Failure (2018 edition). The indicators of liver failure related etiologies, including gender, age, anticoagulant enzyme Ⅲ (ATⅢ), total bilirubin (TBil), length of ICU stay, hepatic encephalopathy, underlying disease (liver cirrhosis and liver cancer, etc.) and usage of artificial liver were analyzed. According to the 6-month follow-up results after discharge, the differences in the etiological indicators of died and survival patients and the outcome of patients with different types of liver failure were analyzed. Results:A total of 369 patients were enrolled, including 134 (36.3%) with liver failure not caused by HBV and 235 (63.7%) with liver failure caused by HBV. The male with HBV-related liver failure was 4.34 times higher than female (cases: 191 vs. 44), which was higher than non-HBV-related liver failure (1.03 times, cases: 68 vs. 66). The 6-month follow-up showed that the proportion of male with HBV-related liver failure who died and survived was significantly higher than that of female (78.76% vs. 21.24% in died patients, 92.86% vs. 7.14% in survival patients, both P < 0.01). The age of died patients in the non-HBV-related liver failure group was significantly higher than that of the survival patients (years: 58.53±0.15 vs. 54.38±3.01, P < 0.05), and the ATⅢ level was significantly lower than that of the survival patients [(32.20±6.43)% vs. (38.63±2.74)%, P < 0.05]. The length of ICU stay of the died HBV-related liver failure group was significantly shorter than that of the survival patients (days: 23.77±11.74 vs. 35.51±2.85, P < 0.01). The 6-month mortality after discharge of HBV-related liver failure combined with liver cancer was significantly higher than that of non-HBV-related liver failure (12.34% vs. 2.24%, P < 0.01), but there was no significant difference in 6-month mortality after discharge of patients receiving artificial liver and those with hepatic encephalopathy and cirrhosis between different types of liver failure groups. Conclusions:HBV is the main cause of liver failure. Patients with HBV-related liver failure were younger and had a longer hospitalization period, which was conducive to the recovery of the disease. HBV-related liver failure accompanied with liver cancer is the main factors of death. The ATⅢ has the potential value to reflect the disease outcome.
