From March 2004 to March 2005, 43 patients (49 hips) admitted to Department of Orthopedic Surgery, Fushun Central Hospital for minimally invasive total hip arthroplasty (THA) were selected, including 22 male and 21 female aged 22-79 years. All patients underwent THA with cementless prosthesis. The preoperative Harris scores were (46.2?5.3). For comparison, 35 patients (43 hips) were selected undergoing standard THA at the same period, including 22 male and 13 female, aged 31-78 years; 16 patients underwent THA with mixed prosthesis (cementless prosthesis for acetabulum; cemented prosthesis for the femur), and the others with cementless prosthesis. Their preoperative Harris scores were (43.4?4.6). The perioperative bleeding, operation time, incision length, postoperative functional recovery, and prosthetic position were compared. The THA was succeeded in all patients, and all subjects were followed up for 13.1 months averagely. The perioperative bleeding, drainage, blood transfusion and incision length in minimally invasive THA group were significantly less than standard group (P

Objective To explore the initial effects of the treatment of proximal femoral nail-helical blade (PFNA) in elderly patients with intertrochanteric fracture of the incomplete lateral wall type. Methods A total of 25 patients were enrolled in this study including 8 cases of type A2, 17 cases of type A3 according to AO classification. All patients under-went three-dimensional CT scan. In all patients with type A2 fracture, there were 6 cases with coronal plane fracture on the greater trochanter, and PFNA was used instead of DHS when an iatrogenic fracture occurred in 2 patients. All other patients were treated with closed reduction and fixed with PFNA. Results All patients healed and the average healing time was 11 weeks, one patient fell down once again and the fracture occurred on the shaft, when a long PFNA was used, both of the frac-tures healed 14 weeks after surgery. In all of the 25 patients,1 patient died due to cerebral hemorrhage 13 months after sur-gery;2 patients needed walking aids due to the presence of osteoarthritis of the knee and calf muscular venous thrombosis was diagnosed in 3 cases. No complications were found in the other patients, such as infection, nonunion and fixation failure. According to the Harris hip score system, there were 14 cases of“excellent”,8 cases of“good”,2 cases of“fair”and1 pa-tient of“poor”.Conclusion The PFNA treatment can provide a good fixation for intertrochanteric fractures of incomplete lateral wall type, which allow patients to do exercise early and achieve an excellent initial outcome.

Objective To explore the clinical value of tissue synchronization imaging(TSI) in assessment of the characteristics of myocardium asynchrony in patients with ischemic cardiomyopathy(ICM). Methods Thirty-eight patients with ICM were divided into two groups: 26 patients without left bundle branch block(LBBB) in group A, and 12 patients with LBBB in group B. The control group consisted of 26 normal healthy subjects. According to 2D color,the characteristics of myocardium motion in each group were compared by TSI. The time for reaching systolic velocity peak(Ts) and early diastole velicity peak(Te) were measured separately in 12 segments. Standard deviations of Ts(Ts-SD) and Te(Te-SD) as well as difference of Ts(Ts max-min) and Te(Te max-min) of all 12 segments were calculated. The myocardium synchronization were assessed in each group. Results ①91.8% segments in the control group showed normal, with only 8.2% segments were slightly prolonged. TSI of all the ICM patients showed an obvious uneven chroma distribution from green to yellow and then to red. There were far more yellow or red segments than in the control group. ②Ts-SD.Ts max-min of LV 12 segments were significantly prolonged in all ICM groups compared with that in the control group ( P <0. 05). Systolic asynchrony was more obvious in group B than in group A. ③Te-SD,Te max-min of LV 12 segments were significantly prolonged in ICM groups than in the control group ( P < 0. 05). Diastolic asynchrony was more obvious in group B than in group A( P < 0. 05). ④Compared with that in the control group, postsystolic shortening(PSS) was common in patients with ICM. 32. 4% segments of group A were detected PSS.and 56. 0% segments of group B were detected PSS. Conclusions Left ventricular systolic and diastolic mechanical asynchrony is obvious in patients with ICM and PSS is common among them. Systolic and diastolic mechanical asynchrony is more severe in ICM patients with LBBB. TSI is the optimal means to evaluate the characteristics of asynchronous myocardial contraction.

Objective:To investigate the relationship between herpesviridae and malignant or benign laryngeal diseases.Method:128 paraffin-embedded laryngeal squamous cell carcinoma and laryngeal epithelium hyperplastic lesions were detected by polymerase chain reaction (PCR) and PCR-ISH for herpesviridae. Result:HSV-1 was detected in 10 cases by PCR,among them 3 were laryngeal squamous cell carcinoma (LSCC),1 was carcinoma in situ(CIS),4 were laryngeal polyps and 2 were laryngeal keratosis. Except 1 LSCC and 1 CIS, 8 of 10 cases were positive while detected by PCR-ISH. In benign diseases, signals were shown from basal layer to superficial cell; in malignant lesions, the signals were scattered in the diseases.Conclusion:Most of laryngeal diseases were not related to herpesviridae, but HSV-1 may acts as initiator in the development of a few cases.

Objective To study the maternal blood glucose management of gestational diabetes mellitus during the labor and relationship of maternal blood glucose in labor and neonatal blood sugar. Methods A prospective study on maternal blood glucose monitoring and control during labor was carried in 40 pregnant women with abnormal glucose metabolism. We adjusted maternal blood glucose by low-dosage constant insulin drop during labor. Results Maternal blood glucose in labor arranged between 3.8 ~ 11.2 mmol/L,and low-dosage constant insulin drop was used in 17 cases (42.5%). The neonatal blood glucose was (4.0?1.5)mmol/L following delivery and (3.9?1.0)mmol/L at 24-hour postpartum. There were 2 cases with neonatal hypoglycemia. The neonatal blood glucose of the rest 23 cases was (4.2?1.5)mmol/L,and (3.9?1.0)mmol/L at 24-hour postpartum,and 1 case with neonatal hypoglycemia. There was no the difference of the blood glucose level of newborns between mothers with abnormal glucose metabolism and the normal pregnant women. Conclusion It is necessary to monitor and control the blood glucose level by low dose constant insulin during labor in pregnant women with abnormal glucose metabolism.
