Objective To probe the surgical approach and effect on upper abdominal malignant tumor infiltrating pancrea. Methods Thirty patients with upper abdominal malignant tumor infiltrating pancreas or tissue around pancrea were treated by radical resection on primary tumor combined pancreaticoduodenectomy. Results Three patients died in 1 month after operation due to multiple organ failure. The patients with gallbladder cancer and metastatic lymph nodes fixed behind caput pancreatis were followed up averaged 35 months. The patients with gastric antrum carcinoma infiltrating caput pancreatis were followed up averaged 31 months. The patients with recurrent gastric cancer infiltrating caput pancreatis were followed up averaged 13 months. The patients with pancreatic and duodenal invasion by cancer of hepatic flexure of colon were followed up averaged 41 months. The patients with hilar cholangiocarcinoma and metastatic lymph nodes fixed behind caput pancreatis were followed up averaged 11 months. Conclusion The patients with upper abdominal malignant tumor infiltrating pancreas should be operated by radical resection on primary tumor combined pancreaticoduodenectomy, which can increase the rate of tumor resection, and be expected to prolong the survival period.

[Abstrct] Objective The deformity of severe varus knee (varus angulation > 15°) can be treated by many ways in primary total knee arthroplasty , but the efficacy and cost are different. The topic of this study provides a new surgery: autograft (wedge grafts) implant and substitute medial tibial bone defects. Methods From Jan. 2006 to Jan. 2014 , a retrospective study was conducted in the First Affiliated Hospital of BaoTou Mendical College. Out of 687 patients, 721 primary knees were operated. Bone defects in proximal tibia (varus angulation >15° ) were encounted in 16 patients in 21 knees in the pattern of non-inclusive slope bone defects in the mean varus degree of 27°. Their IBM was 31 kg/m2. The average age of patients was (63 ± 5) years. The score of clinical knee society score (KSS) before operation was 18 on average. Among of them, the pain score were 12 points, the average range of motion (ROM) were 12 points. the average funtional score were 20 points. During operation,the slope bone defect of the medial tibial plateau was tailored into wedge-shaped ladder bone defect by osteotomy,and then the defect was filled with the resected tibial plateau autograft in which the thickness and shape were matched completely. The high-intensity cortical part of the autograft was placed in the rim to sustain the tibial prosthesis. Three months after operation ,patients started to walk without the help of crutch. Results The average followup period was 5.3 y , We observed that an average postoperative scores of clinical KSS from 42 points to 88 points with the score of functional KSS from 57 points to 92 points. Fusion was observed by trabeculae crossing from the graft to the tibial metaphysis on plain films at least 6 mouths without collapse, stress fracture, untight and bone ununion. Confirmation of vascularization of the graft was observed in bone scans of nuclide. showing increased uptake in the operated area. Inflammatory makers were normal. Conclusion Autograft (wedge grafts) reconstruction of medial tibial bone defects, is of high rate of healing in implant bones, good restoration of the function and low cost.

Objective To evaluate the risk of chondral injury during anterior cruciate ligament (ACL) reconstruction using a double cross-pin femoral fixation device via the anteromedial portal in Chinese cadavers. Methods Nine specimens of the knee (6 left ones and 3 right ones) were taken from 5 male and 4 female conservative cadavers of Chinese adult. The average age of the cadavers were 34.8 (26 to 45)years old. Femoral tunnel drilling and cross-pin guide insertion were performed using the Rigidfix Cross Pin device through the anteromedial portal. The ACL reconstructions were simulated at 3 entrance points of the cross-pin (0°, 45° and 90° relative to the horizontal plane) . The risks of chondral injury were statistically analyzed when the cross-pin entrance point was at the 3 different positions relative to the femoral chondral surface. Results The incidence of chondral injury was 100% when the Rigidfix cross-pin guide was at 90° relative to the horizontal plane. When the Rigidfix cross-pin guide was at 45° and 0° the incidences of chondral injury were 66. 7% and 22. 2% respectively. Conclusion Since there is always a risk of chondral injury when the Rigidfix cross-pin device is used to reconstruct ACL via the anteromedial portal, the anteromedial portal is not recommended for the ACL reconstruction using Rigidfix femoral fixation.

Objective To investigate the protective effect of 3,3′-diindolylmethane (DIM) on radiation-induced injury in mouse hematopoietic system. Methods Thirty C57BL/6 mice were randomly divided into control group, 2 Gy irradiation group and 2 Gy irradiation+DIM group (n=10 for each group). Mice of control group received sham irradiation, and the other two groups accepted 2 Gy 137Cs γ-ray total body irradiation. Mice in 2 Gy irradiation +DIM group were intraperitoneally injected 75 mg/kg DIM 30 min before irradiation. Mice of other two groups were treated with reference solution. After 7 d and 15 d of 2 Gy irradiation, the peripheral blood samples were collected to count the number of bone marrow nuclear cells (BMNCs). The level of reactive oxygen species(ROS) was measured by DCFH-DA. The levels of colony forming units-granulocyte-macrophage (CFU-GM) were also detected. Results The numbers of white blood cell (WBC), platelet count (PLT), BMNCs and CFU-GM were significantly decreased and the ROS level of bone marrow cells increased significantly in the irradiated group than those of control group (P<0.05). Compared to 2 Gy irradiation group, the numbers of WBC, PLT, BMNCs and CFU-GM were significantly increased in 2 Gy irradiation +DIM group, and the level of ROS was decreased significantly (P<0.05). Conclusion DIM has a protective effect on hematopoietic cells following radiation-induced injury, which may be related with the decreased ROS level.

Objective To investigate the effect of music electroacupuncture on perifocal ferric ions and neuronal apoptosis and the brain water content in rats with acute cerebral hemorrhage and explore the mechanism of its action on acute cerebral hemorrhage.Methods One hundred and twenty-eight healthy adult male Wister rats were randomized to normal, model, electroacupuncture and music electroacupuncture groups. In each group, four time points of 6 hrs, 24 hrs, 3 days and 7 days were set up, eight rats each time point. A rat model of acute cerebral hemorrhage was made using collagenase. In the electroacupuncture and music electroacupuncture groups, point Baihui was connected to the anode and point Taiyang to the cathode, 2 voltage was used as a selection parameter and electroacupuncture lasted 30 min. Intracerebral perifocal ferric ions and neuronal apoptosis and the brain water content were measured at four time points of 6 hrs, 24 hrs, 3 days and 7 days after model making.Results Intracerebral ferric ion content was higher in the model, electroacupuncture and music electroacupuncture groups of rats than in the normal group at 6 hrsafter model making (P<0.05), lower in the electroacupuncture and music electroacupuncture groups than in the model group at 24 hrs, 3 and 7 days after model making (P<0.05) and lower in the music electroacupuncture group than in the electroacupuncture group at 3 and 7 days after model making (P<0.05). Intracerebral neuronal apoptosis was higher in the model, electroacupuncture and music electroacupuncture groups of rats than in the normal group at 6 hrs after model making (P<0.05) and lower in the music electroacupuncture group than in the electro- acupuncture group at 7 days after model making (P<0.05). The brain water content was higher in the model, electro- cupuncture and music electroacupuncture groups of rats than in the normal group at 6 and 24 hrs after model making (P<0.05), lower in the electroacupuncture and music electroacupuncture groups than in the model group at 3 days after model making (P<0.05) and lower in the music electroacupuncture group than in the electroacupuncture group at 7 days after model making (P<0.05).Conclusions Music electroacupuncture has a benign regulating effect on intracerebral perifocal ferric ions, inhibits neuronal apoptosis around hematoma in the early stage and reduces cerebral edema in rats with acute cerebral hemorrhage. Its therapeutic effect is superior to that of electroacupuncture.

OBJECTIVE To investigate the phlegm etiology and the prevention measures of respiratory tract infection in 89 cases with heavy type hepatitis in hospital.METHODS From Jan 2004 to May 2007,the phlegm from respiratory tract hospital infection patients were studied retrospectively.RESULTS The main respiratory tract pathogens were the G-bacillui(44.5%),G+ cocci(23.2%),Candida albicans(16.8%),Aspergillus(9.0%) and yeast-like fungi(4.5%).CONCLUSIONS The investigation of the etiology suggests that the prevention of respiratory tract infection be the main measure to decrease hospital infection in heavy type hepatitis patients.

Objective:To find the rate of anxiety and depression in peritoneal dialysis (PD) patients,and the relationship between these emotion disorder and PD processes.Method:88 PD patients were studied, their mood state was evaluated with Hamilton Anxiety Scale and Hamilton Depression Scale. Nutritional indexes, residual renal function and dialysis adequacy, and inflammation status were also recorded as well as history of cardiac-cerebral vascular disease. These patients were followed for 2 years.Result:44.3% patients were detected as anxiety, and 56.8% depression. Higher SGA was associated with higher Hamilton anxiety/depression scale. Patients with higher anxiety and higher depression had lower serum albumin, lower protein intake, lower body index, and lower mid-arm muscle area and fat area. Anxiety and depression is related to cardiac-cerebral vascular diseases and diabetes.There was no significant relationship between Hamilton anxiety/depression score and patient's survival.Conclusion:There is a high rates of anxiety and depression in PD patients and it may be a potential risk factor of malnutrition.
