To explore the relationship between serum total bile acid concentration and fetal prognosis in patients with intrahepatic cholestasis of pregnancy (ICP).A total of 131 ICP patients were divided into mild and severe ICP groups according to serum total bile acid concentration.And another 100 normal subjects during the same period were selected as control group.Their medical records and fetal prognoses were analyzed.The serum total bile acid,liver enzyme and lipid concentration of ICP patients were all significantly higher than those of the controls (P < 0.01).The fetal prognoses of ICP patients were significantly different with those of controls (P < 0.05).A high serum level of total bile acid of ICP patients may produce serious adverse effects on fetal prognosis.

[Objective]To explore the curative effect of the three diamen sional external fixation frame and limited internal fixation in treating the comminuted fracture of the shaft of humerus.[Method]Twenty-eight patients of the comminuted fracture of the shaft of humerus were treated from Jan 2000 to May 2006.According to the AO/ASIF,there were 5 cases of the B1 type,3 cases of the B2 type,9 cases of the B3 type,6 cases of the C1 type,4 cases of the C2 type,1 case of the C3 type.All of them were treated by the three diamensional external fixation frame and limited internal fixation of the screws or wires,and all of them were given the reasonable rehabilitation training at 3 day after the operation.The curative effect of the operation,the complications,the fracture healing and the function appraisal were analyzed.[Result]The 28 patients were followed-up for 10~15 months(average 13 months),27 cases had the frature healed and the healing rate was 96.4%.The healing period of the fracture lasted from 12 weeks to 33 weeks,average 19.5 weeks.Only 1 case was not healed.The functions of the shoulder and the elbow were normal,the excellent rate was 92.8%.[Conclusion]The three diamensional external fixation frame and limited internal fixation is a better method in treating the comminuted fracture of the shaft of humerus.It fits the rule of minimal-invasive-biology. The operation is simple,and the fixation is reliable,the function is satisfactory.

Objective To decrease radiation induced toxicities especially mucostis in patients with locally advanced nasopharyngeal carcinoma( NPC ) who underwent concurrent radiochemotherapy, the maximum tolerated dose and dose limited toxicities of capecitabine combination with cisplatin were observed. Methods From Aug 2006 to Oct 2007, 24 patients with intensity modulated radiotherapy(IMRT) and concurrent chemotherapy with capecitabine and cisplatin for nasopharyngeal carcinoma(stages Ⅲ-Ⅳ) were enrolled in this study. There were four dose-level groups of Capecitabine[625-1250 mg/(m2 ·d) , d1-14]and fixed cisplatin dose[20 mg/(m ·d) ,d1-5) ]MRI and CT scan were used for evaluation of tumor shrinkage. Treatment related toxicities were evaluated according to the common toxicity criteria( NCI-CTC Version 3.0). Results The acute side-effects include Grade 3 or Grade 4 mucosal toxicity(lasting for at least 5 d) and Grade 3 or Grade 4 non-mucosal toxicity were evaluated. Group 625 mg/m2 and Group 825 mg/m2 had none, Group 1000 mg/m2 had 6 patients and Group 1250 mg/m2 had 3 patients for mucosal toxicity, which were the main dose-limited toxicity and relevant to the dose of capecitabine apparently( P < 0. 05 ). There was also a trend of increase by the dose level of capecitabine for other toxicities. The median follow-up time for all patients was 28. 5 months. The locoregional recurrence occurred in 2 patients and distant metastasis in 2 patients. Two-year overall survival rate and locoregional control rate were 100% and 91.7%, respectively.Complete response and partialresponse were found on MRI or CT scan in patients of 29. 2% at the end of treatment and 83. 3% after three months, respectively. Conclusions The combination regimen of capecitabine and cisplatin is safe and effective according to the preliminary result. Toxicities related to radiochemotherapy for NPC were significantly associated with the dose level of chemotherapy.

Objectiye To explore the expression of COX-2 and VEGF and its clinical significance in non-Hodgkin lymphoma (NHL). Methods The expression of COX-2 and VEGF were detected by immunohistochemistry in 42 cases of NHL and 20 cases of lymph node with benign pathological change. Results The positive rate of COX-2 and VEGF was 45.24% and 73.81% in NHL respectively. The expression rate of VEGF was positively correlated with that of COX-2 in tissues of NHL ( x2 = 4. 63, P < 0. 05).The expression of COX-2 was related to clinical stage and histopathologic grade of NHL ( x2 = 5.43, P <0. 05), but it had no association with gender, age, B symptoms, and IPI. The expression of VEGF was significantly related with aggression, B symptoms and IPI ( x2 =8. 979, 8. 893,6. 434, P <0. 05), but it had no association with age, gender and clinical stages. Conclusion COX-2 and VEGF may be involved in NHL tumorgenesis, and COX-2 may accelerate angiogenesis by increasing VEGF expression. Specific COX-2 inhibitors may be a novel therapeutic approach for NHL.

In surgery operations, wound should be cleaned with warm sterilized saline solution. In order to reach rapidly warming the washing solution from the room temperature during the surgery, we designed a thermostatic medical infusion pump. The present paper mainly presents researches on the two temperature control methods in the standby mode and in the flushing mode of the system. In the standby mode, the traditional proportional-integral-derivative (PID) control algorithm was adopted. In the flushing mode, dynamic characteristics of the system was changed in real time, which made the thermostatic control process more complex, and the fitted control function combined with the PID control algorithm was adopted in this mode. The temperature control parameters were adjusted in real time according to the initial temperature and the flow rate of the washing solution to obtain a constant temperature of the washing solution, no matter how the initial temperature and the flow rate are changed. The experiment results showed that this kind of control system performed well with a high accuracy.

Objective To evaluate the effects of health management of stomatology on the marginal bone resorption of minimally invasive implant in the elderly.Method Tottally 54 implants were placed in 37 elderly patients of missing teeth in maxillary molar areas and the patients were randomly divided into health management group and control group.Patients in the group of health management were guided to master the proper techniques of oral hygiene practices before and after the implantation and periodontal maintenance were carried out carefully until 1 year after loading of restoration.In the control group, oral hygiene was applied. X-ray and CBCT examinations were made and implant marginal alveolar bone loss (MBL) was measured 3, 6, 9, 12 months after loading with Planmeca PROMAX3D software. Besides, 3, 6, 9, 12 months after loading, improved plaque index (iPLI), modified bleeding index (mBI) and probing depth (PD) were also recorded. SPSS 15.0 was applied to analyze the data. Result Differences in diastolic and systolic blood pressure and changes in heart rate in patients during the intraoperative period were (8.86 ± 0.31) mmHg(1 mmHg=0.133 kPa), (19.18 ± 0.22) mmHg, (20.19 ± 1.84) times/min, which were significantly lower than those of the control group values [(16.55±1.08) mmHg, (28.31±2.30) mmHg, (20.19±1.84) times/min] (P<0.05 or 0.01);at 12 months after the load around the implant in oral health management group, the values of MBL and mSBI were 2.6 (2, 4), 2.1 (2, 4), which were significantly better than control group [4.3(3, 7), 4.3(3, 7)] (P<0.01);simultaneously, there was significant difference in the values of MBL and PD between experimental group (1.42 ± 0.03, 0.77 ± 0.24) and control group (1.59 ± 0.04, 0.54 ± 0.17) (P<0.01). Conclusion Well-performed health management of peri-implant could reduce the MBL and keep healthy soft tissue environment around implants.
