1.Surgical strategies and techniques of laparoscopic surgery in hepatobiliary, splenic and pancreatic diseases
Chinese Journal of Digestive Surgery 2016;15(9):868-871
Laparoscopic surgery in hepatobiliary,splenic and pancreatic diseases is being widely used.However,the incidence of postoperative complications is relatively higher due to the complexity of the operative procedures.Surgeons are expected to have familiarity with normal and variant anatomy,as well as a good command of prevention and management of bleeding.Different separation techniques should be used based on the different characteristics of tissues.Moreover,digestive tract reconstruction is the technical bottleneck in laparoscopic hepatobiliary,splenic and pancreatic surgeries,and depending on the team work.Different anastomotic methods should be applied according to patients' condition.Three-dimensional laparoscopy and Da Vinci robot surgical system have greatly promoted the development of complex laparoscopic surgery in hepatobiliary,splenic and pancreatic surgeries.Comprehensive perioperative management and enhanced recovery after surgery are the guarantee of safe and quick postoperative recovery,which also fully embody the advantages of minimally invasive surgery.

Pancreatic adenocarcinoma is a highly malignant tumor and its prognosis is poor. The key factors for cure and prolonged survival are early detection, adequate evaluation of resectability and surgical resection with microscopic tumor clearance. Surgeons should pay attention to standardize operative procedures to increase the R0 resection rate. Whipple specimens should be inked and examined carefully. Postoperative adjuvant radiotherapy and chemotherapy are beneficial in the prevention of local tumor recurrence and distant metastasis. Inter-disciplinary cooperation and multimodality treatment are helpful to improve the prognosis and quality of life of patients with pancreatic cancer.

Pancreatic cancer is highly malignant with a poor prognosis. The resectability and prognosis of early pancreatic cancer are much better than the advanced, so early diagnosis is crucial for saving patients' lives. Because the symptoms of pancreatic cancer are non-specific, most of the patients are misdiagnosed as gastrointestinal or hepatobiliary diseases. Early diagnosis rate of pancreatic cancer can be greatly improved by combined application of tumor marker detection, endoscopic ultrasound, computed tomography, positron emission tomo-graphy, and etc. Early screening of high-risk population has been advocated by the experts, and its value in early diagnosis of pancreatic cancer has been confirmed by relevant studies. The colaboration of multiple pancreatic surgery centers in conducting prospective studies and setting gnidlines for the pancreatic cancer diagnosis, and relevant fundamental reseaches should also be emphasized.

AIM: To investigate the effects of low-dose theophylline on differentiation of the naive T lymphocyte. METHODS: Naive T lymphocytes and monocytes were isolated from cord blood in neonate. Theophylline (10 mg?L-1 ) was added in naive T lymphocytes and monocytes which stimulated by PHA (200 mg?L-1 ) for 3 days, and the differentiation of T cells was analyzed by flow cytometry. Cytokines were measured by enzyme linked immune-sorbent assay ( ELISA ). RESULTS: Theophylline significantly promoted differentiation fromTh1 cells to naive T cells ( P

Purpose:A comparison of the therapeutic effect studied by ?-rag,selec- tive asteriography and TAIC on advancing gastric carciomas with HM(hepatic metastasis) in 41 cases and NHM(without hepatic metastasis)the other 35 were reported.The correla- tion of primary and metastatic lesions including the efficacy of TAIC were also evaluated, Materials and Methods:Every case was undergone CAG;in addition LGA+CA were al- ways performed in cases of carcinoma of cardiac end of stomach so as CHA,either CA or LGA for gastric antrum carcinomas;while FDM(5Fu+CDDDP+MMC)were the drugs used for the majority of the patients.Results showed the number with large extent gastric carcinoma(≥one part of gastric zone)accompanied by moderate to severe deformaties in HM group were obviously greater than those of the NHM group(P

AIM: To investigate the mechanism of anti inflammatory action of theophylline on asthma. METHODS: Nineteen asthmatic patients were administered 200 mg sustained release theophylline twice daily for 4 weeks. The numbers or levels of CD4 +T lymphocytes, eosinophils, interleukin(IL) 5 and interferon gamma (IFN ?) in sputum pre and post administration were measured by direct immunofluorescene technique, Wright's stain and enzyme linked immunosorbent assay, respectively. The symptom scores and lung function were also evaluated. RESULTS: Theophylline treatment significantly improved symptom scores, FEV 1.0 and FEV 1.0 %(P 0.05 ). The mean (range) serum theophylline concentration in final steady state was 7.9 ( 3.9 - 14.7 ) mg?L -1 . CONCLUSION: The anti inflammatory action of theophylline in asthma may result from reduction of IL 5 production in the airways.

Farnesoid X receptor(FXR), a member of the metabolic nuclear receptor superfamily, plays key roles in maintaining bile acid and lipid homeostasis.FXR is highly expressed in the entero-hepatic system where it transcriptionally regulates bile acid metabolism, intestinal barrier function and liver regeneration, etc.Loss or down regulation of FXR expression can lead to a lot of diseases, such as cholecystolithiasis, biliary cirrhosis,primary hepatic carcinoma, colon carcinoma, etc.Activation of FXR may protect against or provide a pharmacological target for these diseases.

An inductively coupled plasma mass spectrometry ( ICP-MS) was developed for the direct determination of Be, Na, Mg, Al, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Zr, Mo, Sr, Cd, Ba, Pd, Ag, Sn, Au and Pb in lithium hexafluorophosphate. The sample was dissolved with absolute ethyl alcohol to analyze the above 26 impurity elements in the solution by ICP-MS. The condensation and deposition of high concentrations of carbon in mass cone interface and ion lens, which will decrease the sensitivity of element analysis, can be avoided effectively by introducing O2 to plasma. The mass spectral interferences of polyatomic ions to analytes were corrected by collision reaction cell (CRC). The matrix matching method was used to corrected matrix effect. Satisfactory linearity of each working curve of 26 impurity elements was obtained. The correlation coefficients being over 0. 9995, the detection limits for the investigated elements were in the range of 0. 6-32 ng / L, the relative standard deviation of each element within 2. 5% -7. 3% , and the recovery of each element at 90. 6% -108. 6% . The method had been applied to the determination of trace elements in lithium hexafluorophosphate with satisfactory results.
