ObjectiveTo investigate the clinical efficacy of oral/ gastric tube/ jejunal tube administration or retention enema of Qingjie Huagong Formula （清解化攻方， QHF） mirabilite abdominal bag external application combined with conventional western medicine in patients with acute pancreatitis （AP）. MethodsA prospective， randomized， double-blind， placebo-controlled trial was conducted. A total of 128 AP patients were enrolled and randomly assigned to a control group and a treatment group， with 64 cases in each group. The control group received placebo and conventional western medicine， while the treatment group additionally received oral/ gastric tube/ jejunal tube administration or retention enema of QHF， and mirabilite abdominal bag external application. Both groups received treatment from admission to discharge as one complete course， with the maximum treatment duration not exceeding 14 days.The primary outcome was the severity grading of AP. Secondary outcomes were clinical efficacy， laboratory indicators including white blood cell count （WBC）， C-reactive protein （CRP）， procalcitonin （PCT）， blood urea nitrogen （BUN）， lactate （Lac）， and D-dimer， gastrointestinal function recovery indicators including time to relief of abdominal pain， time to recovery of bowel sounds， and time to resumption of enteral nutrition， total fluid volume administered within 24 h after admission， intra-abdominal pressure， length of hospital stay， hospitalization costs， and incidence of complications. ResultsDuring the treatment period， 3 cases dropped out in the control group and 9 cases in the treatment group， leaving 116 cases for final analysis （55 in the treatment group and 61 in the control group）. After treatment， the markedly effective rate and overall effective rate in the treatment group were 69.09% （38/55） and 92.73% （51/55）， respectively， which was higher than 49.18% （30/61） and 80.33% （49/61） in the control group. The severity of the disease in the treatment group was significantly lower than that in the control group （P＜0.05）. Compared to the control group， the treatment group showed significantly reduced levels of WBC， CRP， PCT， BUN， Lac， and D-dimer； the time to relief of abdominal pain， time to recovery of bowel sounds， and time to resumption of enteral nutrition were significantly shortened； the fluid volume administered within 24 h after admission and intra-abdominal pressure were significantly reduced， as well as the length of hospital stay and hospitalization costs （P＜0.05 or P＜0.01）. The incidences of acute kidney injury， systemic inflammatory response syndrome， and infected pancreatic necrosis in the treatment group were significantly lower than those in the control group （P＜0.05）. ConclusionQHF combined with conventional western medicine can significantly improve the inflammatory status of AP patients， promote gastrointestinal function recovery， reduce intra-abdominal pressure and fluid resuscitation requirements， lower the risk of certain complications， and shorten the length of hospital stay.

Objective To investigate the influencing factors of treatment decision dilemma in the pa-tients with intracranial aneurysm.Methods A total of 210 patients with intracranial aneurysms hospitalized in the neurosurgery department of this hospital from January to December 2022 were selected as the research subjects.The questionnaire survey on the patients was conducted by using the general data questionnaire,De-cision Dilemma Scale (DDS),Perceptive Social Support Scale (PSSS) and Hospital Anxiety and Depression Scale (HADS).Results The scores of decisional dilemma,perceived social support,anxiety and depression of the patients with intracranial aneurysm were (38.08±14.05) points,(50.59±3.38) points,(11.12±3.46) points and (9.56±2.11) points respectively.The multiple linear regression analysis showed that the age,fam-ily per capita monthly income,aneurysm diameter,social support and anxiety were the main influencing fac-tors of treatment decision dilemma in the patients with intracranial aneurysm (P<0.05).Conclusion The de-cision-making dilemma in the patients with intracranial aneurysms is in a moderate level.Medical care staff should for-mulate the targeted decision support measures according to the patient' s age,economic status,aneurysm size,patient's social support and anxiety situation to help the patients to improve their decision-making level.

Objective:To explore the status of social alienation among survivors of nasopharyngeal carcinoma and analyze its influencing factors.Methods:This study was a cross-sectional study. From October 2021 to January 2022, 200 survivors of nasopharyngeal carcinoma reviewed in the radiotherapy department of the First Affiliated Hospital of Guangxi Medical University were investigated by General Data Questionnaire, General Alienation Scale (GAS), Cancer Fatigue Scale (CFS) and Self-Perceived Burden Scale (SPBS).Results:The total score of GAS in survivors of nasopharyngeal carcinoma was (37.47 ± 2.88) points. The total scores of GAS were positively correlated with the total score and each dimension score of CFS and SPBS ( r values were 0.312-0.524, all P<0.01). Multivariable linear regression showed that the duration of diagnosis, whether or not having hearing loss, the number of symptoms, cancer fatigue and self-perceived burden were the main influencing factors of social alienation in survivors of nasopharyngeal carcinoma( t values were -3.99-4.86, all P<0.05), which could explain 49% of the total variation. Conclusions:Clinical medical staff should attach importance to social alienation of surviors of nasopharyngeal carcinoma. More attention should be paid to patients with less than one year of diagnosis, a large number of symptoms and hearing loss, and targeted intervention should be conducted to reduce the degree of social alienation of patients and promote their integration into society.

A new method to express oligomerized feruloyl esterase (FAE) in Pichia pastoris GS115 to improve the catalytic efficiency was developed. It was realized by fusing the foldon domain at the C-terminus of FAE, and the fusion protein was purified by histidine tag. Fusion of the feruloyl esterase with the foldon domain resulted spontaneously forming a trimer FAE to improve the catalytic performance. The oligomerized FAE and monomeric FAE were obtained by purification. The apparent molecular weight of the oligomerized FAE was about 110 kDa, while the monomeric FAE about 40 kDa, and the optimum temperature of the oligomerized FAE was 50 °C, which is the same as the monomeric one. The optimal pH of the oligomerized FAE is 5.0, while the optimal pH of the monomer FAE is 6.0. When compared with the monomeric ones, the catalytic efficiency (kcat/Km) of the oligomerized FAE increased 7.57-folds. The catalytic constant (kcat) of the oligomerized FAE increased 3.42-folds. The oligomerized FAE induced by foldon have advantages in the catalytic performances, which represents a simple and effective enzyme-engineering tool. The method proposed here for improving the catalytic efficiency of FAE would have great potentials for improving the catalytic efficiency of other enzymes.
