BACKGROUND Gallbladder rupture is common in laparoscopic cholecystectomy because the gallbladder is usually in acute or chronic inflammation *** gallstones may sometime be spilled into the peritoneal cavity,resulting in intra-abdominal ab-scess if the gallstones were not *** diagnosis of intra-abdominal ab-scess caused by unretrieved gallstone can usually be correctly identified in the routine imaging studies,such as abdominal ultrasonography or computed tomo-graphy(CT).Here we present a case of abscess formation from unretrieved gall-stone following laparoscopic cholecystectomy,which mimics the imaging findings of metastatic gallbladder *** SUMMARY This case described a 78-year-old man who received laparoscopic cholecystectomy and gallbladder adenocarcinoma was diagnosed after *** adjuvant chemotherapy,the following up abdominal CT showed several small nodules at right upper abdomen and peritoneal carcinomatosis is *** laparoscopic surgery for the excision of seeding tumor was conducted and the pathological diagnosis of the nodules and mass was inflammatory tissues and gallbladder *** Spilled gallstones are a common complication during laparoscopic cholecystectomy and some gallstones fail to be retrieved due to the size or the restricted view of laparoscopic *** spilled gall bladder stones,surgeons may consider regular computerized tomography follow-up,and if necessary,laparoscopic examination can be used as a means of confirming the diagnostic and treatment.

Evaluation of remediation process with soapberry derived saponin for removal of heavy metals from contaminated soils in Hai-Pu, Taiwan

引用

Journal of Environmental Sciences 2013年第6期25卷 1180-1185页

作者： Jyoti Prakash Maity Yuh Ming Huang cheng-Wei Fan chien-cheng chen Chun-Yi Li Chun-Mei Hsu Young-Fo Chang Ching-I Wu chen-Yen chen Jiin-Shuh Jean Department of Earth and Environmental Sciences "National" Chung Cheng University 168University Rd. Department of Soil Environmental Science "National" Chung-Hsing University Department of Biotechnology "National" Kaohsiung Normal University Graduate School of Landscape "National" Chin-Yi University of Technology Department of Earth sciences "National" Cheng Kung University

The use of a biodegradable natural plant-based surfactant extracted from soapberry is proposed for the remediation of Ni, Cr and Mn from industrial soil site in Hai-Pu, Taiwan. Batch experiments were performed under variation of fundamental factors （saponin concentration, pH, and incubation time） for metal remediation. Removal of Ni and Mn were increased with increasing saponin concentration （0.015-0.150 g/L）, whereas the removal of Cr was increased upto 0.075 g/L saponin. The Ni, Cr and Mn were removed significantly （p 〈 0.05） at near to the neutral and slightly acidic （pH 5 to 8） conditions. Removal efficiency of Ni （99%） from the soil was found to be greater than that of Cr （73%） or Mn （25%） in the presence of saponin at a concentration of 0.150 g/L at pH 5. The removal percentage increased with incubation time where the removal of Ni was faster than that of Cr and Mn. The result indicates the feasibility of cco-friendly removal of heavy metal （Ni, Cr and Mn） from industrial soil by soil washing process in presence of plant derived saponin.

Evidence-Based Dampness-Heat ZHENG(Syndrome) in Cancer: Current Progress toward Establishing Relevant Animal Model with Pancreatic Tumor

引用

Chinese Journal of Integrative Medicine 2024年第1期30卷 85-95页

作者： JIAO Ju-ying cheng chien-shan CAO Zhang-qi chen Lian-yu chen Zhen Department of Integrative Oncology Fudan University Shanghai Cancer CenterShanghai(200032)China Department of Oncology Shanghai Medical CollegeFudan UniversityShanghai(200032)China

Cancer is one of the deadliest diseases affecting the health of human beings. With limited therapeutic options available, complementary and alternative medicine has been widely adopted in cancer management and is increasingly becoming accepted by both patients and healthcare workers alike. Chinese medicine characterized by its unique diagnostic and treatment system is the most widely applied complementary and alternative medicine. It emphasizes symptoms and ZHENG(syndrome)-based treatment combined with contemporary disease diagnosis and further stratifies patients into individualized medicine subgroups. As a representative cancer with the highest degree of malignancy, pancreatic cancer is traditionally classified into the "amassment and accumulation". Emerging perspectives define the core pathogenesis of pancreatic cancer as "dampness-heat" and the respective treatment "clearing heat and resolving dampness" has been demonstrated to prolong survival in pancreatic cancer patients, as has been observed in many other cancers. This clinical advantage encourages an exploration of the essence of dampness-heat ZHENG(DHZ) in cancer and investigation into underlying mechanisms of action of herbal formulations against dampness-heat. However, at present, there is a lack of understanding of the molecular characteristics of DHZ in cancer and no standardized and widely accepted animal model to study this core syndrome in vivo. The shortage of animal models limits the ability to uncover the antitumor mechanisms of herbal medicines and to assess the safety profile of the natural products derived from them. This review summarizes the current research on DHZ in cancer in terms of the clinical aspects, molecular landscape, and animal models. This study aims to provide comprehensive insight that can be used for the establishment of a future standardized ZHENG-based cancer animal model.

World Journal of Gastroenterology 2011年第3期17卷 379-384页

AIM: To study the computed tomography (CT) signs in facilitating early diagnosis of necrotic stercoral colitis (NSC). METHODS: Ten patients with surgically and pathologically confirmed NSC were recruited from the Clinico-Pathologic-Radiologic conference at Chang Gung Memorial Hospital, Taoyuan, Taiwan. Their CT images and medical records were reviewed retrospectively to correlate CT findings with clinical presentation. RESULTS: All these ten elderly patients with a mean age of 77.1 years presented with acute abdomen at our Emergency Room. Nine of them were with systemic medical disease and 8 with chronic constipation. Seven were with leukocytosis, two with low-grade fever, two with peritoneal sign, and three with hypotensive shock. Only one patient was with radiographic detected abnormal gas. Except the crux of fecal impaction, the frequency of the CT signs of NSC were, proximal colon dilatation (20%), colon wall thickening (60%), dense mucosa (62.5%), mucosal sloughing (10%), perfusion defect (70%), pericolonic stranding (80%), abnormal gas (50%) with pneumo-mesocolon (40%) in them, pericolonic abscess (20%). The most sensitive signs in decreasing order were pericolonic stranding, perfusion defect, dense mucosal, detecting about 80%, 70%, and 62.5% of the cases, respectively. CONCLUSION: Awareness of NSC and familiarity with the CT diagnostic signs enable the differential diagnosis between NSC and benign stool impaction.
