AIM: To investigate the bile acid pool size after cholecystectomy whether or not correlated to the gastrointestinal migrating myoeiectric complex (MMC) in guinea pigs. METHODS: Gallbladder motilities were assessed before cholecystectomy. Furthermore, we continuously monitored interdigestive gastrointestinal motilities using bipolar electrodes in conscious guinea pigs before and after surgery at 4 wk in standard diet group and high cholesterol diet (cholesterol gallstone) group. Total bile acid pool sizes were measured by isotope dilution method at meantime. RESULTS: After cholecystectomy, there were parallel falls in duration of phase Ⅰ, Ⅱ, Ⅲ and MMC cycle duration but increase in amplitude in the guinea pigs with normal gallbladder function, and in the guinea pigs with cholesterol stones. However, There were not significantly differences. On the other hand, the bile acid pool was definitely small in the GS guinea pigs compared to normal guinea pigs and became slightly smaller after cholecystectomy. Similarly, bile acid in gallbladder bile, fecal bile acid was slightly increased in GS guinea pigs after cholecystectomy, to the same degree as normal. These differences, however, were not significant. CONCLUSION: It is concluded that in the guinea pigs with normal gallbladder function, and in the guinea pigs with cholesterol stones: (1) Cholecystectomy produce a similar but less marked trend in bile acid pool; and (2) MMC are linked to enterohepatic circulation of bile acids, rather than surgery, which is consistent with changes of the bile acid pool size. As a result, gastrointestinal dyskinesia is not involved in occurrence of postchole cystectomy syndrome.

Journal of Cancer Therapy 2015年第4期6卷 293-298页

作者： qianhe Liao Shuhong Hu Department of Pathology Shuyang People’s Hospital Shuyang China Department of Gynecology and Obstetrics The Third Affiliated Hospital of Wenzhou Medical University Wenzhou China

Meigs’ syndrome represents a triad of pleural effusion, ascites, and an ovarian tumor, which is usually benign, occurring together. We describe here 2 patients with Meigs’ syndrome and 2 patients with pseudo-Meigs’ syndrome. Hydrothorax and ascites symptoms in 4 patients are of outstanding performance characteristics of Meigs’ syndrome and pseudo-Meigs’ syndrome. Ovarian tumors were found by clinical examination and surgically removed. Postoperatively, these signs of hydrothorax and ascites were dissolved completely. Conclusions: These cases highlight the difficulties that may be encountered in the management of patients with Meigs’ syndrome, including potential misdiagnosis of the tumor as a malignant ovarian neoplasm that may influence the medical and surgical approach, and the adverse impact that Meigs’ syndrome can have on the patient’s condition. Clinical doctors should be alert to this kind of disease under pathological diagnosis in the absence of a clear effect of chemotherapy or radiotherapy and to prevent unnecessary harm to the patient.

Strategies to accelerate bubble detachment for efficient hydrogen evolution

Chinese Chemical Letters 2024年第1期35卷 196-207页

In the process of electrocatalytic water splitting, the management of gaseous products is an important task. Timely detachment of gaseous products from the electrode surface and the electrolyte is beneficial to the reduction of energy consumption of the electrolytic cell. In the existing industrial electrolytic cells, the circulating pump drives the electrolyte flowing to discharge the gaseous products. Up to now, several much more advanced strategies have been explored to deal with the negative effects of bubbles. In this review, we summarized various strategies for bubble detachment, including electrode design, external field imposing and system upgrading. We also elaborated the principle, functional features, practicability, advantages and limitations of each method. Finally, challenges and perspectives are also provided for the further development of advanced bubbles detachment strategies for efficient hydrogen evolution.

Thermoacoustic theory of graphene films considering heat transfer of substrate materials

引用

Chinese Journal of Acoustics 2018年第2期37卷 191-201页

作者： BIAN Anhua LI Shuang XING qianhe HUANG Xu FAN Xueliang LI Cheng School of Rail Transportation Soochow University

Based on thermoacoustic theory, a coupled thermal-mechanical model for graphene films is established, and the analytical solutions for thermal-acoustic radiation from a graphene thin film are obtained. The sound pressure of the graphene film generator on different substrates is measured, and the measurement data is compared with the theoretical results. The frequency response from the experimental results is consistent with the theoretical ones, while the measured values are slightly lower than the theoretical ones. Therefore, the accuracy of the proposed theoretical model is verified. It is shown that thermal-acoustic radiation from a graphene thin film reveals a wide frequency response. The sound pressure level increases with the frequency in the low frequency range, while the sound pressure varies smoothly with frequency in the high frequency range. Thus it can be used as excellent thermal generator. When the thermal effusivity of the substrate is smaller, then the sound pressure of grapheme films will be higher. Furthermore, the sound pressure decreases with the increase of heat capacity per unit area of grapheme films. Results will contribute to the mechanism of graphene films generator and its applications in the design of loudspeaker and other related areas.
