In our study, we adopted a schedule plan management of the Project Management Body of Knowledge(PMBOK)in the management practice of the expefimental research on "The Research in Teaching and Inheritance of Experience of Famous and Veteran Doctors of TCM "which was supposed by " tenth five years "plan of national science and technology as a key program. We tried to establish a project planning based on the special features of TCM and the characters of the project. This planning played a significant support role in the top project design and ensuring the smooth implementation of the research.

Objective To summarize the diagnosis and surgical treatment of the cavernous transformation of portal vein (CTPV). Methods Clinical data of 63 patients with adult CTPV trea-ted in our hospital from 1976 to 2006 were retrospectively analyzed. Results The diagnosis of CT-PV was comfirmed according to (1) The main symptoms were repeated haematemesis, hemafecia, hy-persplenotrophy, hypersplenia and normal hepatic function. (2) B uhrasonography or ultrasonic Doppler manifested that portal vein thinning or obstruction or embolism, honeycomb appearance con-duit can be seen around. Portal vein frequency spectrum can be seen in the honeycomb appearance con-duit. (3) CT and MR scan materials were exhibited that the main portal vein and its branches lost the normal shape and had the shaggy edge. (4) percutaneous splenoportography or selective arteriography of superior mesenteric artery showed that occlusion of the main branch of portal vein at the porta hepa-tis was revealed, and a masslike network of tortuose veins around the porta hepatis and many small ir-regular veins radiating from the network to the liver were demonst rated. Splenectomy and devaseu-larization was performed in 23, spleneetomy and splenorenal shunt in 32, portal systemic shunt plus porta-azygous devascularization in 8. Portal hypertension was treated first in CTPV with disease of biliary tract. No death happened. The rascult of haemogram recovered in a short period of time.Conclusion Once the patients are diagnosed to suffer from adult CTPV, they should receive explora-tory laparotomy. It is important to choose the most effective treating method for the disease.

Objective　To summarize the methods of diagnosis and operation of carcinoma of the extrahepatic bile ducts. Methods　The clinical data of 100 cases of carcinoma of the extrahepatic bile ducts which were treated in our hospital from 1972 to 1999 were retrospectively analysed. In this series, there were 68 cases of the cancer located in the upper portion of exlrahepatic duct(proximal cancer), 12 in midder portion(midder cancer), 18 in lower portion(distal cancer), and 2 in whole bile duct. Results　The initial symptom was upper abdominal discomfort or vague pain, abdominal distension, weakness, weight loss and progressive jaundice. BUS, CT and MRI were scatheless. If the intrahepatic bile duct dilatation or extrahepatic cholestatic jaundice were revealed, PTC(13 cases in this series) or ERCP(42 cases in this series) were to further determine the location of tumor. According to the position and type of the tumor, the different operations were selected. Twenty-five cases(36.8%) of the proximal cancer were resected, including 15 cases of type Ⅰ treated with localresection or “skeletonization” resection, 9 cases of type Ⅱ treated with resection of the tumor and caudate lobe, 1 case of type Ⅲb treated with resection of the tumor, caudate lobe and left hepatic trisegmentectomy. Nine cases(75%) of midder cancer were resected. After resected the proximal and midder cancer, bile duct reconstruction by Roux-en-Y hepaticojejunostomy was performed on all the cases. Fourteen cases(77.8%) of distal cancer were treated by pancreatoduodenectomy. The total resection rate in this series was 48%. Of the cancer resected cases, 35 were followed up, the five-year survival rate was 58%. 32 of the 52 cases without cancer resection were followed up, and all of them died one to one and half year after operation. Conclusions　BUS, CT and MRI are the first selective methods for early diagnosis of the carcinomas of extrahepatic bile duct. If needed, PTC or ERCP should be done because of these methods have more accurate diagnostic value. Surgical resection of the tumor is the only likelihood for effective treatment.

BackgroundThe etiopathogenesis of major depressive disorder （MDD） is strongly associated with neuroinflammation. MDD is a highly heterogeneous psychiatric disorder， and the disease subtyping is an essential step for the identification of biological markers. The presence of psychomotor retardation seriously affects the prognosis of MDD， whereas the underlying mechanism is not yet completely clear. A potential involvement of granulocyte colony-stimulating factor （G-CSF） and macrophage colony-stimulating factor （M-CSF） in the pathogenesis of MDD with psychomotor retardation has been suggested in previous studies， but little detailed research has been completed. ObjectiveTo analyze the correlation of plasma G-CSF and M-CSF levels with psychomotor retardation in patients with MDD， and to explore the potential biological underpinnings of psychomotor retardation in MDD. MethodsA total of 50 MDD patients who met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） and attended the outpatient clinics of Shanghai Mental Health Center from April 2018 to April 2019 were included. The severity of symptoms was assessed using the Hamilton Depression Scale-17 item （HAMD-17）. According to the retardation factor in HAMD-17， patients with a score of ≥8 were included in retardation group （n=22）， and those with a score below 8 were included in non-retardation group （n=28）. Another 22 age- and sex-matched healthy controls were concurrently recruited. Plasma G-CSF and M-CSF levels were measured in all subjects using Luminex liquid suspension chip technology. Spearman correlation analysis was adopted to verify the correlation of retardation factor score in HAMD-17 with plasma G-CSF and M-CSF levels in MDD patients. ResultsPlasma G-CSF levels were decreased in MDD patients compared with healthy controls ［57.34（39.24， 83.15）pg/mL vs. 71.47（61.20， 79.99）pg/mL， Z=-2.098， P<0.05］. A statistical difference was found in plasma G-CSF level ［63.92（54.60， 89.43）pg/mL vs. 47.80（33.41， 74.66）pg/mL vs. 71.47（61.20， 79.99）pg/mL， H=8.247， P=0.016］ and plasma M-CSF level ［20.05（16.05， 22.23）pg/mL vs. 13.05（11.43， 17.50）pg/mL vs. 18.95（14.59， 22.88）pg/mL， H=7.620， P=0.022］ among retardation group， non-retardation group and healthy control group. The post hoc pairwise comparisons using Bonferroni correction indicated that plasma G-CSF level was lower in non-retardation group compared with healthy control group （adjusted P<0.05）， and plasma M-CSF level was higher in retardation group compared with non-retardation group （adjusted P<0.05）. The retardation factor score in HAMD-17 was positively correlated with plasma M-CSF level in MDD patients （r=0.348， P<0.05）. ConclusionThe prevalence of psychomotor retardation in MDD patients may be related to abnormally elevated plasma M-CSF level. ［Funded by Shanghai "Science and Technology Innovation Action Plan" Project in Medical Innovation Research Field （number， 21Y11905600）； Shanghai "Science and Technology Innovation Action Plan" Project in Natural Science Field （number， 21ZR1455100）； Shanghai Mental Health Center Scientific Research Project （number， 2021-YJ02）］
