Objective To explore the feasibility of microinvasive technique in high level malignantesophageal obstruction and to provide the palliative therapy that can't be dredged by traditional methods. Methods There were 39 patients suffered from high level esophageal obstruction,involving the segments from esophageal circular pharynx to 12mm below. Tube-reticular nitinol metal stents woven by single thread were placed in orally to dredge the esophagus under fluoroscopic guidance after repeated tolerant expanding performance through expandable catheter. Interventional chemical therapy were administrated through blood-supply vessels. Results Thirty nine patients were grafted with 46 high level esophageal stents. 34 patients accepted 156 times of interventional chemical therapy. All patients restored with fine residue diet without showing side-effects except slight pain and tolerant uncomfortable feeling. The survival rate of the patients with both interventional chemical therapy and stents was longer than those with stent therapy alone. Conclusion Cervical high level segment of esophagus shouldn't be the restricted zone in the management of inner-stents. Interventional chemical therapy showed tumor-inhibiting effect in the cervical malignant diseases.

Objective To compare the effects of adjustable pressure drainage device, negative pressure ball drainage and drainage bag drainage on patients with the total hip arthroplasty. Methods The silicone drainage ball with negative pressure, the urine collection bag, the infusion set′s regulator were used to make adjustable pressure drainage device. 120 cases of total hip arthroplasties from January to December in 2015 were chosed and divided randomly into 3 groups based on the sequence of operation notifications. In 40 cases, drainage bag were used (control group 1), 40 cases with negative pressure ball drainage (control group 2) and 40 cases with adjustable pressure drainage device (experimental group). Total postoperative bleeding, the blood transfusion amount, swelling (the thickness of hematoma) and the nursing workload of the three groups were compared. Results The total postoperative bleeding, the blood transfusion amount, the thickness of hematoma and the nursing workload in the experimental group were (775.1±130.5) ml, (3.5±1.3) mm, (180.2±29.9) ml, (34.5±5.2) min. The total postoperative bleeding, the blood transfusion amount, the thickness of hematoma and the nursing workload in the control group 1 were (889.4 ± 160.8) ml, (5.2 ± 1.1) mm, (285.9 ± 30.4) ml, (40.6 ± 7.4) min and in the control group 2 were (876.2±156.7) ml, (4.3±1.2) mm,(208.3±33.3) ml, (50.3±8.5) min. Compared the data of the experimental group and the control group 1, the difference was of statistically significance (t=3.49-15.68, P < 0.01). Compared the data of the experimental group and the control group 2, the difference was of statistically significance (t=2.86-10.03, P<0.01). Conclusions The effects of adjustable pressure drainage device are better than the drainage bag and negative pressure drainage ball. It can effectively reduce the postoperative bleeding and the swelling degree, and bring a lot of relief to the patients and lots of convenience to the nursing work. The method is affordable, reliable and safe which should be promoted in the primary hospital.

Background and purpose:Angiofollicular lymphoid hyperplasia(Castleman's disease,CD) is a rare kind of abnormal disease with lymphoid hyperplasia. We analyzed the clinical data of 21 patients with pathologically-confirmed CD. Methods:Twenty-one cases,including 10 males and 11 females with a mean age of 38.6 years,with CD were collected from January 1971 to December 2007 in this study. The disease was divided into localized type(n=19) and disseminated type(n=2) . The clinical data,CT images and pathological and surgical results were restrospectively analyzed. Results:All cases were categorized as hyaline vascular type. In 19 cases with localized type of CD,the lesion presented as a solitary soft-tissue mass with a mean diameter of 5.2 cm,located at the left and right hilus of the lung(n=3 and 2 respectively) or in the interior lung(n=3) ,in the thoracic wall(n=2) or in the mediastinum(n=9) . Two cases of disseminated type were characterized by many groups of thoracic lymphadenopathy with a mean diameter of 2.3 cm,without other organ involvement. On plain CT scan,the mean CT value was 42 Hu. After contrast administration,obvious homogeneous enhancement was observed in arterial phase with CT value of 112 Hu. The preoperative misdiagnosis by CT was 90.5%. Conclusion:CD have no specifi c CT characteristic,its verifi cation is mainly based on pathologic examination. Surgical resection for localized type of CD is curative,but for disseminated CD,multidisciplinary therapies are recommended.

Objective:The feasibility of a minimally invasive cosmetic transbilical laparotomy was studied in fifty-seven pediatric patients.The advantages of this technique will be discussed.Methods:The circumferential incision was made following the ring fold of the right umblilicus,which was less than 2700.The peritoneum was opened in the midline via rectus abdominis.Intra-peritoneal lesions were detected and explored.The surgical procedures were able to be carried out either inside or outside of the peritoneum.After closure of peritoneum,the umbilical incision was closed subcutaneously with an absorbable suture.Results:From January 2001 to January 2005,58 procedures via transumbilical route have been done in 57 pediatric patients.None of those cases required conversion to a traditional abdominal incision.The duration of surgery was from 20 to 170 minutes.All patients were discharged five days postoperatively and follow-up was conducted from 3 months to 4 years.No complications were observed in all but one patient.This patient had a leaking anastamosis.No visible scars were present and the cosmetic results were excellent.All patients had shorter hospital stay and lower operating cost.Conclusion:Transumbilical approach is a feasible,safe,economical,minimally invasive procedure with excellent cosmetic results which appears to be superior to traditional procedures.It suggests that the transumbilical route should be widely used clinically and might be applicable for elder children and possibly would be of benefit in the treatment of other conditions.

Objective To investigate the effects of extended care on the treatment compliance and the quality of life on discharged elderly patients with chronic heart failure. Methods One hundred and eight patients were randomly assigned to the experimental group and the control group with 54 patients in each, the experimental group received extended care for 1 year, including regular telephone and visit follow-up, supporting medical care, diet care, rehabilitation exercises and supervision of self-care. The control group underwent routine health education before discharge. Medical compliance and self-management ability were compared three months, six months and 1 year after discharge, evaluation score of life quality were also compared at discharge and one year after discharge between the two groups. Results There were no significant differences in medication, diet and regular follow-up visits between the two groups. However, the patients in the experimental group showed better compliance than the control group in the self-testing of urine, body weight,and recording of symptoms, body signs and required exercises. Additionally, the patients in the experimental group had higher scores than the control group in the daily life-skills, happiness and the quality of life. Conclusions The extended care significantly improved the treatment compliance and the quality of life in the elderly patients with chronic heart failure.

Objective To study the effects of ginkgo biloba extract(GBE)on c-reactive protein(CRP) and tumor necrosis factor-α(TNF-α)in serum and alveolar lavage fluid(BALF)from rats with chronic obstructive pulmonary disease(COPD). Methods 90 rats were randomly divided into groups A,B,C,D,E and F. There were 15 rats in each group. The rat model of COPD were established in groups B,C,D,E and F. Groups C and D were given intraperitoneal injections with GBE from day l to day l4 and day 29 to day 42. Groups E and F weregiven intraperitoneal injections with erythromycin from day l to day l4 and day 29 to day 42. After the end of experi-ment ,the contents of CRP and TNF-α in serum and BALF were detected in all groups. Results The contents of CRP and TNF-α in the serum and the BALF were markedly lower in groups C,D,E and F than in group B (P<0.05);and the contents of CRP in the serum and the BALF and TNF-αin the BALF were lower in groups C, E and F than in group D(P<0.05). Conclusions GBE can inhibit the airway and systemic inflammatory response in COPD rats. Early intervention is more effective.

Cell morphometry method was applied in courting a nd analyzing 12 ultrastruc-ture morphological parameters of the rough endoplasmic reticulum and ribosome from 10 female patients of the simple breast carcinoma in the late stage by pathological diagnosis． The best equation was set up with stepwise regression analysis was as follows: y=0.22+0.503N6-013N7． Due to above equation, selecting the best parameters were the surface density of free ribosome N6 and specific surface of rough endoplasmic reticulum N7． They could be used to distinguish the normal cell-apparatus from carcinoma cell-apparatus． These results show that N6 and N7 in varying degrees could provide fixed quantity basis for the prognosis of breast carcinoma．
