[Objective]To study the application and clinical results of the adjustable erternal fixation of ankle joint(AEFA) in orthopedic surgery.[Method]From January 1999 to May 2005,45 cases(55 feet)of equinovarus deformity were treated with orthopedic surgery.In order to preventent the deformity relapsion,the patients were assigned to two groups.The A group(26 cases,32 feet)patients were treated with the adjustable erternal fixation of ankle joint(AEFA).The B group(19 cases,23 feet)patients were treated with plaster immobilization.The orthopedic surgery effect and functions of ankle joint were studied and tested with independent sample t test and x~2 test.[Result]Thirty-eight cases were fellowed-up for 3 months to 9 years(averaged 19 months).There were significant difference between the two groups in the functions of ankle joint.[Conclusion]The new apparatus can effectively prevent the foot-drop deformity and enhance the function of ankle joint.

Objective To evaluate the diagnosis and surgical management of appandiceal mucoceles.Method The clinical data of 50 patients with appendiceal mucoceles surgically treated from January 2004 to January 2008 were reviewed retrospectively. Result The correct preoperative diagnosis rate was 8%.Eight patients were complicated with pseudomyxoma peritonei.The canceration rate was 4%.All the 50 patients recovered uneventfully after the surgery.There was no complications,no recurrence during the follow-up period,including the 2 patients with canceration. Conclusion It was difficult to make correct diagnosis of appendiceal mucoceles preoperatively.The diagnosis should always be in mind if the B-type ultrasonography indicated a cystoadenoma.Abdominal CT coupled with necessary digestive image examinations may improve the correct diagnosis rate.Some patients may be complicated with pseudomyxoma peritonei.Occasionally this abdominal mass was also associated with malignancy.Surgery is the management of choice,and the prognosis is good.

Objective To explore the changes of the levels of CA-125 antigen(CA125) and vascular endothelial growth factor (VEGF) in serum and peritoneal fluid in patients with endometriosis (EMT), and the relationship with EMT. Methods One hundred and twenty patients with EMT (EMT group)and 98 patients with uterine fibroids (control group) were enrolled in this study. The levels of CA125 and VEGF in serum and peritoneal fluid were detected by enzyme linked immunosorbent assay (ELISA), and the results were compared. Results The levels of serum CA125,VEGF in EMT group were significantly higher than those in control group:(40.31±11.14) kU/L vs.(24.71±9.19) kU/L,(59.75±6.87) ng/L vs. (36.38±8.12) ng/L, there were significant differences(P<0.05). The levels of serum CA125,VEGF inⅠ-Ⅱphase andⅢ-Ⅳphase in EMT group had no significant differences ( P>0.05). The levels of peritoneal fluid CA125,VEGF in EMT group were significantly higher than those in control group:(311.46± 107.29) kU/L vs.(158.17± 55.42) kU/L,(73.28 ±10.40) ng/L vs. (40.21 ±9.84) ng/L, there were significant differences (P<0.05). The levels of peritoneal fluid CA125,VEGF in Ⅲ-Ⅳ phase were significantly higher than those in Ⅰ-Ⅱ phase in EMT group:(387.41±70.91) kU/L vs. (308.42±81.21) kU/L, (69.22±7.13) ng/L vs. (55.44±8.23) ng/L, there were significant differences (P<0.05). In EMT group, the levels of CA125 and VEGF in serum were significantly lower those in peritoneal fluid:(40.31±11.14) kU/L vs. (311.46±107.29) kU/L, (59.75±6.87) ng/L vs. (73.28 ±10.40) ng/L, there were significant differences (P<0.05). Conclusions The levels of CA125 and VEGF in serum and peritoneal fluid are closely related to EMT. Peritoneal fluid in monitoring of EMT may be more sensitive and reliable than serum.

Primary aldosteronism (PA) is a common form of secondary endocrine hypertension,which is characterized by hypertension,hypokelamia,myathenia,elevated serum aldosterone concentration and suppressed plasma renin activity.Besides,accumulating research evidences showed that parathyroid hormone (PTH) level was elevated in patients with primary aldosteronism,accompanied by secondary hyperparathyroidism.This review systemically introduces the interaction between aldosterone and PTH in PA patients.

Objective To establish a recombinant retroviral vector containing insulin-like growth factor-1(IGF-1) gene and to provide the basis for the application of IGF-1 in treating nervous system diseases such as stroke.Methods The plasmid pcDNA3.1-IGF-1 was cut by EcoR I/Xho I,and subcloned to retroviral vector pLXSN,resulting in the recombinant plasmid(pLXSN-IGF-1.)The recombinant IGF-1 expression vector was evaluated by using enzyme cutting and sequencing.By the Lipofectamine 2000,pLXSN-IGF-1 was transferred to packaging cell line-pA317.Culture supernatant of these cells was detected for titration of the recombinant virus.Results The two fragments from recombined IGF-1 eukaryotic expression vector by EcoR I and Xho I represented 400?bp and 6.0?kb by agarose electrophoresis,and PCR showed positive fragment which was about 400?bp long,and sequence analysis showed the same sequence as expected.The cell line pA317-IGF-1 was established,and average virus titer of the recombinant virus in the culture supernatant was about 6.5?10~5 CFU/ml.Conclusion A recombinant retroviral containing IGF-1 gene was successfully constructed.

Objective To establish a nested-real-time-PCR for the detection of IL-21R mRNA in peripheral blood mononuclear cells(PBMC)of patients with rheumatoid arthritis,and explore its clinical significance.Methods The outer primers of span intron and inner primers were designed for nested-real-time-PCR.To increase specific template,the concentration of primers and enzyme,cycle times were decreased in the first amplification,and the real-time fluorescent quantity assay was performed in the second amplification.The ?-actin gene was used as internal reference,and the results were presented as the ratios of IL-21R mRNA to ?-actin mRNA.Results IL-21R mRNA was detected in 60 patients with RA and 30 healthy controls.The expression of IL-21R mRNA gene in the patients with RA was increased,and the statistical analysis has significant differences(P0.05),but a significant difference was found in the patients of grade III compared with those of grade I and II(P

Objective: To construct the Behavior Inhibition Scale. Methods: The compilation of items was in accordance with the content validity of seven kinds behavior inhibition. The Self Consistency and Congruence Scale and SCL-90 were also applied as validity index. Results: Factor analysis on 660 subjects rating on original 86 items of Behavior Inhibition Scale yielded seven factors composed of 42 items, measuring the inhibition of help-seeking, self-confidence, independence, negativeness, alienation, dominate, and refuse, respectively. Behavior inhibition correlated significantly with SCL-90 and self congruence, and significant sex and education differences were also detected. Conclusion: The Behavior Inhibition Scale has good reliabilities and well validated.

Objective: To investigate the characteristics of Behavior Styles personality dimension among subjects of dif- ferent age, genders, marriage status, and occupations. Methods: After subjects fulfilled Chinese Personality Scale (QZPS), score differences of Behavior Styles and its sub- factors were compared among age, genders, marriage status, and occupa- tions. Results: Significant differences were detected among different age, genders, and occupations. Males have lower scores than females; the elder the subjects, the higher the scores; executives and technicians have the same scores, and both have higher scores than workers and peasants. Some interactions were also significant. Conclusion: There were sig- nificant differences among subjects of different gender, age, and occupation.

Objective To evaluate the incidence of nasopharyngeal hemorrhage after radiotherapy of nasopharyngeal carcinoma (NPC) in order to adjust adequately the dose of fractionated stereotactic radiosurgery (FSRS). Methods Eighteen NPC patients were treated by FSRS following conventional radiotherapy of D T65～74?Gy. Of them, 5 patients (T 4) with uncontrolled lesions received a boost dose of 24～40?Gy/6～8 f and 13 patients (T 2～3 ) with local recurrence received their second course of treatment with different regimens. Group A: 8 patients received routine radiotherapy 30～40?Gy followed by FSRS 24～30?Gy/6～9 f; Group B: 5 patients received FSRS 40～42?Gy/6～8 f alone. Results The frequency of nasopharyngeal hemorrhage was 3/5 for skull base invasion (T 4 ) lesions. The incidence of morbidity for re radiation after local recurrence of T 2～3 tumor was 1/8 in Group A and 1/5 in Group B.Conclusions The frequency of nasopharyngeal hemorrhage is high in skull base invasion by NPC (T 4).Therefore the dose of FSRS combined with conventional radiotherapy should be limited when re treating local recurrence of NPC.
