Objective To investigate a novel therapeutic strategy in the treatment of lung cancer with diffuse pleural metastasis accompanied by malignant pleural effusion. Methods From December 1978 to February 2003, 55 patients of carcinoma of lung with pleural metastasis underwent the comprehensive therapy characterized by pleuropneumonectomy. A follow-up of all the patients after hospital discharge was conducted. Results Death due to complications was found in 2 out of the 55 patients, but remission and significant improvement of symptoms were found in the rest. A follow-up period ranging from 1 to 25 years revealed that 48 patients survived for 5-40 months (median survival time: 14 months), and 5 patients were still living and well. Conclusion Strict control of the surgical indications and radical removal of the malignant tumor can improve the quality of life and prolong the survival time of patients, even there is already metastasis to the pleura.

Objective To summarize the experiences in diagnosis and treatment of thymoma in 120 cases. Methods 120 patients with thymoma were operated on, and the diagnosis was confirmed pathologically, from January 1994 to December 2003 in our department. According to Masaoka clinical and pathological classification, 54 cases were stage Ⅰ, 32 were stage Ⅱ, 22 were stage Ⅲ, 12 were stage Ⅳ. In 42 cases there were symptoms of myasthenia gravis. Result Total excision was performed in 112 cases and partial excision in 8 cases. When the tumor was beyond stage Ⅱ, postoperative radiotherapy was given. Recurrence occurred in 5 patients 1-7 years after operation. Conclusions Surgical resection is currently the main therapeutic method for tumor of the thymus. The preferred surgical approach was excision of thymoma and removal of perithymic fat in the anterior mediastinum through a median sternotomy. Thymoma is a potentially malignant disease, and the patients with the tumor beyond stage Ⅰ must undergo postoperative radiotherapy. Local recurrence of the tumor should be surgically excised.

Objective To compare the levels of serum CEA, NSE and CYFRA21-1 of patients with lung cancer and those with benign lung diseases, and to evaluate the clinical differential diagnostic value of combined detection of serum CEA, NSE and CYFRA21-1 in patients with lung cancer. Methods CEA, NSE and CYFRA21-1 were determined with enzyme-linked immunosorbent assay in 122 patients with lung cancer and 37 patients with benign lung diseases. The data was analyzed by t test. Results The serum levels of CEA(12.95?33.04ng/ml), CYFRA21-1(4.87?0.638ng/ml) in patients with lung cancer were significantly higher than that in those with benign lung diseases (1.92?0.84ng/ml and 4.87?0.638ng/ml, respectively)(P0.05). The levels of serum CEA, NSE and CYFRA21-1 were related to types of pathology. The highest levels of CEA, NSE and CYFRA21-1 appeared in adenocarcinoma, small cell carcinoma and squamous cell carcinoma, respectively. The level of serum of NSE (26.05?20.69ng/ml) in patients with small cell carcinoma was significantly higher than that of the patients with benign lung disease, adenocarcinoma (11.26?6.97ng/ml) and squamous cell carcinoma (12.71?7.64ng/ml), respectively (P0.05). Conclusion Combined determination of serum levels of CEA, NSE and CYFRA21-1 is helpful in differential diagnosis of lung cancers.

Objective To investigate the in-vitro transdermal permeability of cyclovirobuxine D ethosomes.Methods Ethosomes,liposomes,saturated aqueous solution and 35.5% saturated alcohol solution of cyclovirobuxine D were prepared.The in-vitro transdermal permeability of different kinds of preparations of cyclovirobuxine D was studied by in-vitro permeation experiments.Results Cyclovirobuxine D ethosomes enhanced transdermal flux rate of cyclovirobuxine D and the enhancement ratio was 8.85,superior to liposomes and saturate alcohol.The dermatic hold-up amount of cyclovirobuxine D in 35.5% saturated alcohol solution,liposomes and ethosomes was in a decreasing sequence.Conclusion Compared with the liposomes,the ethosomes can enhance the transdermal flux rate of cyclovirobuxine D,which could increase the systematic action of the drug.

Objective To investigate the clinical efficacy and significance of preoperative superselective endovascular embolization in treatment of patients with vascularized meningioma.Methods 3-9 days before operation, 98 patients with vascularized meningioma underwent DSA and preoperative superselective embilization with PVA particles, gelatin sponge, and silk. The surgical intervention was performed after embolization. Results The vascularized meningioma was mainly supplied by the middle meningeal artery, ascending pharyngeal artery, occipital artery, internal maxillary artery as well as submeningeal artery. After the supplying artery was embolized, tumors' staining in 42 cases disappeared completely and that of 56 cases disappeared totally or partly. Most patients were operated on 3-9 days after embolization. 64 tumors were removed completely, while other 34 cases were removed totally or partly. The average volume of bleeding during the operation was 950 ml in the former and 1 500 ml in the latter.Conclusions The best time for operation is 7～9 days after embolization. Preoperative embolization of the vascularized meningioma contributes to reduce the bleeding significantly during the operation, increase the safety of the operation and improve the total removal of the tumor. It is a safe and effective microinvasive method.

Objective To evaluate the safety of nasogastric tube feeding and nasojejunal tube feeding in early enteral nutrition treatment of acute pancreatitis.Methods Using key words,subject headings,and citation tracing,we searched literatures reporting randomised controlled trials on early enteral nutrition treatment of acute pancreatitis through nasojejunal tube and nasogastric tube in the following databases:PubMed,Embase,Cochrane library,Wanfang,China National Knowledge Infrastructure (CNKI),and VIP published since the founding of the databases up to 2016.Meta-analysis was performed with the selected literature.Results Seven randomised controlled trials with 367 patients were included.Meta-analysis showed that the nasogastric tube group was not inferior to the nasojejunal tube group in the incidence of recurrent abdominal pain,gastrointestinal adverse reaction,the total length of hospital stay,and mortality.Conclusion Enteral nutrition via nasogastric tube is safe and well tolerated,may be a safe approach of nutrition treatment for acute pancreatitis.

Objective To observe the clinical effect of manipulation combined with McKenzie technique on discogenic low back pain. Methods 80 patients were randomly divided into control group (n=39, 1 case was lost) and observation group (n=40). The patients in obser-vation group received manipulation and McKenzie technique, while the control group received manipulation only. All the patients were eval-uated with Oswestry Disability Index (ODI), Visual Analogous Scale (VAS) and Self-rating Depression Scale (SDS) before and 3 weeks af-ter treatment. Results The scores of ODI, VAS and SDS decreased after treatment in both groups (P<0.01). The score of ODI and VAS were lower in the observation group than in the control group (P<0.05), while there was no significant difference in the score of SDS between two groups after treatment (P>0.05). Conclusion Manipulation combined with McKenzie technique is more effective on discogenic low back pain.
