ObjectiveTo evaluate the clinical efficacy of cutaneous branches of reverse second and third dorsal metacarpal artery fasciocutaneous flaps for repair of distal- and middle-segment finger soft tissue defects. MethodsA total of 14 patients with distal- and middle-segment finger soft tissue defects complicated by exposure of the phalanx or tendon were repaired by using cutaneous branches of second and third dorsal metacarpal artery fasciocutaneous flaps ranging between 2.0 cm × 4.5 cm and 3.0 cm × 7.0 cm.ResuitsAll of the skin flaps survived after surgery.Follow-up data during a 6-40 month period showed that the flaps exhibited a satisfactory appearance.They were not fat or clumsy,with a 2-point discrimination of 59 mm,and there was good recovery of finger function.The donor site was able to be directly sutured without dermoplasty.Pigmented linear surgical streaks appeared in the donor site.Conclusion The cutaneous branches of Second and third dorsal metacarpal artery fasciocutaneous flaps provide a good approach for the repair of distal- and middle-segment finger soft tissue defects and functional reconstruction because of convenient dissection,little trauma,sufficient use of the dorsal metacarpal artery.

Objective To evaluate 99tcm-DTPA nuclear dynamic imaging in distinguishing the renal occupied disease.Methods A total of 164 in-patients with renal occupied disease who underwent surgery were included.According to the pathological diagnosis,119 patients had malignant tumors,and 45 patients had benign diseases.All patients’ imaging was retrospectively analyzed.Application of 99Tcm-DTPA nuclear dynamic imaging in renal occupied disease was compared with ultrasonography (US),computed tomography (CT),magnetic resonance imaging (MRI),intravenous pyelogram (IVP),and positron emission tomography (PET)-CT.Results The accuracy rates of different imaging methods in distinguishing between renal malignant and benign disease were 99Tcm-DTPA (84 ％,45 ％),US (72 ％,64 ％),CT ( 91％,92 ％),MRI (50 ％,67 ％),IVP (50 ％, 17 ％), respectively.The diagnostic accuracy rate of PET-CT for malignant tumors was 67 ％.The accuracy rates of 99Tcm-DTPA in distinguishing different phases of renal cell carcinoma were statistically significant (x 2 =83.4, P ＜ 0.01), while the accuracy rates in distinguishing renal cyst from renal angiomyolipoma were not statistically different.With the greater diameter, the diagnostic accordance rate is higher (x 2 =16.05,P ＜ 0.05).Conclusion 99Tcm-DTPA could be used not only to evaluate the renal function quantificationally,but also be helpful to distinguish renal malignant tumor from benign disease.

Objective To investigate the management and control of hypertension in patients with chronic kidney disease(CKD) and its associated factors.Methods Data of 726in-patients with CKD and hypertension who hospitalized in our hospital from March 2009 to April 2010 were studied.Results 91.74％ of patients was treated with antihypertensive medications,and 21.21％, 22.59％, 19.56％, 28.37％ of patients received 1, 2, 3, ≥4 antihypertensive drugs,respectively.42.4％ of patients with CKD and hypertension could be controlled up to the standard,and the mean blood pressure was(137.86±20.75)/(76.30±11.35) mm Hg.There was significant difference among stage 1 plus 2, 3, 4 plus 5 (non-dialysis), 5 (dialysis) kidney diseases, with the hypertension control rate being 50.8％, 46.7％, 42.0％, 33.5％, respectively.The hypertension control rate of non-dialysis patients was significantly higher than that of dialysis (44.9％ vs 33.5％,P＜0.05).There was no significant difference between blood dialysis group and peritoneal dialysis group(32.3％ vs 38.7％, P＞0.05).Multivariate Logistic regression analysis showed that female (OR=1.787, 95％CI 1.045-3.056)and ACEI application (OR=4.378, 95％CI1.830-10.472) were positively associated with hypertension control.Whereas, diabetes (OR=0.415, 95％CI 0.188-0.919)and pulse pressure (OR =0.847, 95％ CI 0.811-0.885) were associated with inadequate blood pressure control.ConclusionsDespite almost universal hypertension treatment is used in patients with CKD and high blood pressure, the hypertension control rate is still suboptimal.Female and ACEI are positively associated with adequate hypertension control, whereas diabetes and pulse pressure are negatively associated with the standard.

OBJECTIVETo investigate the clinical results of the proximal femoral nail antirotation (PFNA) system in the treatment of unstable intertrochanteric femoral fractures.

METHODSFrom September 2006 to September 2009, 90 patients (40 males and 50 females, ranged in age from 64 to 95 years with an average of 73.2 years with unstable intertrochanteric femoral fractures were surgically treated with PFNA. Fifty patients had the fractures in the right hip, and 40 patients had the fractures in the left hip. The fractures were classified according to the AO classification: 11 patients were type A2.1, 21 patients were type A2.2,25 patients were type A2.3 9 patients were type A3.1,6 patients were A3.2 and 18 patients were A3.3. The patients underwent surgery within a mean of 3.2 days(ranged,2 to 20.1 days) from injury. The mean hospital stay was 12.8 days(ranged,7 to 24 days). Closed reduction was achieved in all the patients. Harris hip score were used for the evaluation of clinical effects.

RESULTSThe mean operation time was 36.8 min (ranged, 23 to 110 min) and the mean blood loss was 150 mi (ranged, 100 to 500 ml). The mean follow-up period was 12 months (ranged, 6 to 24 months). All the patients had fracture union. Sixty-nine patients got excellent reduction, 14 good and 7 bad. The mean collodiaphysial angle was 135.60 (ranged, 1260 to 1470). Postoperative complications included secondary varus in 2 patients,calcification at the tip of the greater trochanter in 5 patients, medial thigh pain in 7 patients,and screw cut-out in 1 petient. Ten patients had femoral shortness (mean 9.3 mm,ranging from 8 to 14 mm). The mean Harris hip score was (80.5 +/- 9.8). According to Harris hip scores evaluation system, 26 patients reached an excellent result, 37 good, 18 poor and 9 bad.

CONCLUSIONDue to advantages of high union rate, short operation time, and early postoperative mobilization, PFNA osteosynthesis is an idea method for surgical treatment of unstable intertrochanteric femoral fractures.

Objective To analyze the protective role of intraoperative EMG monitoring in surgical removal of tumors related to the floor of the fourth ventricle and its influencing factors.Methods Intraoperative EMG monitoring was performed during the surgical removal of 32 patients with brain tumor, admitted to our hospital from January 2007 to December 2010; among these 32patients, 11 was conformed as having medulloblastoma, 9 ependymoma, 6 brain stem cavernous hemangioma, 4 brain stem exogenous glioma and 2 hemangioblastoma of the dorsal brain stem. The influencing factors of intraoperative EMG monitoring and the possible damage of cranial nerve nuclei caused by these surgical procedures were analyzed.Results Twenty-one patients enjoyed total removal, 9 sub-total removal and 2 partial removal. Good function protection of patient's posterior cranial nerves was noted in 9 patients, mild impairment in 18 patients, and moderate dysfunction in 5 patients.The influencing factors of EMG monitoring included leaking electric current caused by bipolar coagulation, excessive use of muscle relaxant drugs, changes in depth of anesthesia, and rapid changes of patient′s temperature, saline temperature and blood pressure. Conclusion The intraoperative EMG monitoring can provide evidence about the location of the cranial motor nuclei during the surgical removal of the tumor related to the floor of the fourth ventricle and the function protection of patient’s posterior cranial nerves.

Objective To study the clinical manifestations and treatment methods of hyperprolactinemia (HPRL), a common disorder encountered in clinical practice, and explore its association with prolactinomas. Methods The clinical data, hormone profile and imaging data of 166females with documented HPRL, admitted to our hospital from January 2005 to January 2010, for over a period of 5 years, including 4 years of retrospective analysis and 1 year of prospective study, were retrospectively analyzed. Results Most patients aged 20-40 with abnormal menstruation as their most common symptom; 141 patients (84.9％) appeared abnormal menstruation and 1 14 (68.7％) with galactorrhea. Microadenoma was noted in 62 patients (37.3％), nonfunctioning pituitary macroadenoma involved stalk occurred in 26 patients (15.7％). As compared with that in patients with idiopathic HPRL ([93.9±20.4]ng/mL), the level ofprolactin in patients with microprolactinoma ([161.2±60.6]ng/mL) was significantly higher (P＜0.05); as compared with that in patients with prolactin microadenoma, the level of prolactin in patients with domperidone caused drug-induced HPRL ([240.2±29.4]ng/mL) was obviously increased (P＜0.05). Conclusion We cannot confirm whether a HPRL patient has prolactinomas only through detecting the level of prolactin. Microprolactinoma is the most common cause of HPRL, followed by idiopathic cause.
