Objective To compare the effect oropivacaine combined with fentanyl or sufentanil in labor anal-gesia.Methods 116 cases of maternal birth in obstetrics and gynecology were selected.According to the random number table method,116 cases of parturients were randomly divided into observation group (58 cases,received ropiv-acaine and sufentanil analgesia)and control group (received ropivacaine and fentanyl).In two groups of maternal anesthesia before induction (T0 ),used the drug after 30min(T1 ),60min(T2 ),180min(T3 )detection of the mean arterial pressure (MAP)and heart rate (HR),and digital evaluation table Rating Scale (NRS).The complications of maternal and infant in the two groups were recorded,the change of the mode of delivery and the Apgar score of neo-nates in the two groups were analyzed.Results There were no significant differences in the levels of MAP and HR between the two groups in T0-T3 (tMAP =0.123,1.078,0.212,0.047;P =0.903,0.283,0.832,0.963;tHR =0.033, 0.289,0.288,0.036;P =0.974,0.773,0.774,0.972).The NRS scores in T1 -T3 of the two groups were significantly lower than those in the T0;the T1 -T3 scores of the observation group were (2.21 ±0.36 )points,(1.78 ± 0.24)points,(1.83 ±0.25)points,which were significantly lower than (3.61 ±0.75)points,(3.22 ±0.12)points, (2.84 ±0.26)points of the control group(t =12.816,40.871,21.325,P =0.000,0.000,0.000).In the observation group,there was 0 case (0.00%)had cardiac arrhythmia,the control group had 4 cases (6.90%),and the differ-ence was statistically significant(χ2 =4.143,P =0.042).Two groups of labor analgesia,the way of delivery and birth of the newborn after birth,1min,5min of Apgar score were compared,the differences were not statistically significant (χ2 =0.703,t =0.631,1.149,P =0.402,0.530,0.253).Conclusion Ropivacaine combined with sufentanil or fentanyl in analgesia have no effect in childbirth and maternal vital signs and neonatal,and have good analgesic effect, but ropivacaine combined with sufentanil has stronger analgesic effect,higher safety.

Objective To evaluate the results of less invasive surgical treatment of high energy tibial plateau fracture, which involves limited open reduction, percutaneous screw fixation and Hybrid external fixation. Methods From 1999 to 2002, 12 cases of high energy tibial plateau fracture were treated with Hybrid external fixation. They were 8 males and 4 females. According to Schatzker classification, there were 9 cases of Type Ⅴand 3 cases of Type Ⅵin the group. The average age of the patients was 39.3 years old (ranging from 27 to 48). Results All were followed up for an average of 15 months (ranging from 6 to 27). All the fractures got united, with an average healing time of 3.2 months. All patients achieved 0 to 5 degrees of extension and more than 100 degrees of flexion. The patients had an average knee score of 88.7 and an average functional score of 85.2(Knee Society clinical rating system). 1 case had infection of pin holes, and 2 knees had Grade 2 arthrosis at radiographic check up two years after the operation. Conclusion Hybrid external fixation combined with limited open reduction is appropriate for treatment of the complex tibial fractures, especially those with a poor soft tissue envelope.

Objective Unstable intertrochanteric hip fractures are characterized by comminution of the posteromedial cortex and a fragment of variable size containing the lesser trochanter. This paper is to discuss whether it is necessary to perform reduction and fixation for this fragment. Methods 67 cases of intertrochanteric fractures were treated by dynamic hip screw (DHS) fixation between March 2001 and September 2002 and followed up for a minimum of 1 year. Their treatment results were retrospectively analyzed. Results No nonunion, coxa vara or failure of internal fixation occurred in all these patients. Conclusion If DHS provides stability, screw fixation of the lesser trochanteric fragment is unnecessary.

OBJECTIVE: To study the effect of taspine hydrochloride (TA/HCl) on skin wound healing in rats and its mechanism. METHODS: Bilateral round wounds were made on the backs of SD rats. The effect of TA/HCl on the skin wound was evaluated through determining closure time and contracting ability of the skin wound, observing histopathological characteristics and measuring contents of hydroxyproline (Hyp) and protein in the wound tissue. RESULTS: The closure time of the skin wounds was significantly shorter in the TA/HCl-treated groups than that in the model group. The percentages of wound contraction were higher in the TA/HCl-treated groups than that in the dimethyl sulfoxide (DMSO) control group of the same group (P<0.05 or P<0.01) on the 3rd to 14th days after wounding. The content of the protein in the wound tissue in the TA/HCl-treated group (2 mg/ml) was higher than that in the model group (P<0.05) on the 3rd to 7th days after wounding, and it arrived at the peak on the 7th day and gradually decreased to the normal level in skin tissue on the 14th to 21st days after wounding. The contents of Hyp in the wound tissues in the TA/HCl-treated groups were higher than that in the model group (P<0.05 or P<0.015) on the 3rd to 21st days after wounding, and they arrived at the peak on the 14th day and at the normal level in skin tissue on the 21st day. Histopathological test results showed that TA/HCl could promote the formation of newly born capillaries in the early period of the wound healing. CONCLUSION: TA/HCl has the ability of promoting skin wound healing in rats, and it can also accelerate the growth of newly born capillaries and raise the production of protein and collagen in wound tissue.

Objective To investigate the effect of Gum mastic combined with gemcitabine on human pancreatic carcinoma BxPc-3 cells and its mechanism.Methods Cell proliferation and apoptosis were examined using the methyl thiazolyl tetrazolium assay and propidium iodine staining,respectively.After BxPc-3 cells were treated with different concentrations of Gum mastic and gemcitabine,the expression of NF-κB p65 subunit,IkB,Bcl-2 and Bax proteins was detected by Western blot.BxPc-3 cells were injected subcytaneously into nude mice to establish pancreatic xenograft tumors,and the changes of tumor volume were monitored.Results Compared to either single agent,treatment with Gum mastic (40 mg/L) combined with gemcitabine (10 mg/L) for 72 h signi cantly inhibited the proliferation of BxPc 3 cells (P＜0.01).Its rate of apoptosis(45.13±4.01)was more than Gum mastic,gemcitabine(P＜0.01) and control group (5.07 ± 1.37,P＜ 0.01).When cells were treated with gemcitabine in combination with gum mastic in human pancreatic carcinoma BxPc-3 cells for 48 h,the IκB level was increased,whereas NF-κB activation was blocked; the expression of Bax protein was substantially increased,but Bcl-2 protein was down-regulated; gum mastic or combined with gemcitabine could significantly inhibit the growth of pancreatic xenograft tumors (P ＜ 0.05).Conclusions Gum mastic could effectively strengthen the sensitivity of human pancreatic carcinoma BxPc-3 cells to gemcitabine.It may inhibit the expression of NF-κB p65 subunit and Bcl-2 proteins and increase the expression of IκB and Bax proteins.

Postoperative X-ray films showed that the fracture healing time was averagely 5.4 months. Al of the fractures were recovered wel that subtrochanteric fractures, intertrochanteric fractures and femoral shaft fractures were al healed. There was no fracture displacement, internal fixation loosening and varus deformity. Only one case showed difficulties in nail insertion. Excellence rate of Harris hip functional scores was 88.2%postoperatively. Proximal femoral nail antirotation is a reasonable design, and the helical blade can resist the rotation and stabilize the angle. The proximal femoral nail antirotation has better effects, which is an ideal internal fixation for subtrochanteric femoral fractures.

Objective To prospectively assess the influence of intensity-modulated radiotherapy (IMRT) and conventional radiotherapy on quality of life (QOL) in patients with head and neck cancer (HNC) for clinical guidance. Methods From May 2007 to May 2008, 102 HNC patients were enrolled in this study. Fifty-two patients were treated with IMRT and 50 with conventional radiotherapy. In patients with IMRT, at least one parotid gland was spared, and the contralateral submandibular gland was spared in 24 patients. The parotid and submandibular gland were not spared in patient with conventional radiotherapy.QOL was assessed using EORTC QLQ C30 and HN35 questionnaires at 4 time points (before radiotherapy,end of radiotherapy, 2 months and 6 months after radiotherapy). A change of 10% in scores of the instru-ment range had been previously demonstrated to be clinically significant. Results In the study, 94% (31/33) of the QOL domains were worse after IMRT or conventional radiotherapy, including 49% (16/33) with significant difference (U=2.72-5.98, all values of P<0.01) and 33% (11/33) with clinical signifi-cance. At 2 months after radiotherapy, 12% (4/33) of the domains showed clinically significant improve-ment, however, 15% (5/33) of the domains did not show any improvement (U=3.10-5.93,all value of P < 0.01). Continuous improvement in most domains of QOL was shown at 6 months after radiotherapy. Clini-cally and statistically significant improvement were shown in 21% (7/33) of the domains, and some were even better than pretreatment except in dry mouth and sticky saliva scales (U=4.49 , P<0.01 and U=4.87 ,P <0.01). Compared with conventional radiotherapy, the dry mouth and sticky saliva caused by IM-RT were milder (U=4.57,P <0.01 and U=5.57, P < 0.01) and continuous improvement were shown over time after radiotherapy (U=7.23, P <0.01 and U = 7.57, P < 0.01). Similar improvement weren't shown in patients with conventional radiotherapy. Conclusions QOL in HNC patients is significant worse after ra-diotherapy. QOL can be improved continuously over time after treatment except dry mouth and sticky saliva which are the main factors affecting QOL. IMBT, causing less dry mouth and sticky saliva when compared with conventional radiotherapy, has benefits for the preservation of QOL.
