Objective To observe the postoperative analgesic effects of ultrasound-guided transversus abdominis plane block after cesarean section. Methods Forty patients having underwent cesarean section under intraspinal anesthesia were selected, and they were divided into experiment group and control group by random digits table method with 20 cases each. All the patients were given ultrasound-guided transversus abdominis plane blocks when surgery finished. The patients in experiment group were injected 0.25%ropivacaine 20 ml, and the patients in control group were injected 0.9% sodium chloride 20 ml. All the patients received patient controlled intravenous analgesia (PCIA) pump after surgery. The movement and resting visual analog score (VAS), incision VAS at 4, 8, 12 and 24 h after surgery, and the compression time of analgesis pump were compared between 2 groups. The correlated adverse reaction of transversus abdominis plane block were recorded. Results The movement VAS at 4 and 8 h after surgery in experiment group were (4.1±1.7) and (5.3±1.8)scores, and in control group were (6.3±2.0) and (7.0±1.2) scores, and there were statistical differences (P<0.05). The incision VAS at 4 and 8 h after surgery in experiment group were (0.9±0.4) and (1.2±0.8) scores, and in control group were (3.6±2.1) and (6.8±2.4) scores, and there were statistical differences (P<0.05). The compression time of analgesis pump in experiment group was significantly lower than that in control group: (2.8± 1.4) times vs. (4.0±1.9) times, and there was statistical difference (P<0.05). The using dose of tramadol in experiment group was significantly lower than that in control group:(214±12) mg vs. (224±15) mg, and there was statistical difference (P<0.05). All the patients did not appear the correlated adverse reaction of transversus abdominis plane block. Conclusions Ultrasound-guided transversus abdominis plane block is accurate and easy. It provides effectual post-cesarean section analgesia with lower adverse reaction, which is a better choice of multimodal analgesia for cesarean section.

OBJECTIVETo explore the effects of acupuncture with different filiform needles on structure of fascial connective tissues, cellular activity, arrangement and content of collagen fibers in acupoint area of rats.
METHODSA total of 32 SD rats were randomly divided into a blank group, a thin needle group, a medium needle group and a thick needle group, 8 rats in each one. Except for the blank group, rats in the remaining groups were treated with horizontal acupuncture at "Zhongwan" (CV 12) towards Conception Vessel with different filiform needles, and twirling mild reinforcing-reducing method was applied, once a day. Rats in the blank group were treated with identical anesthesia, grasping and fixation. After 3-day intervention, the fascial connective tissue of acupoint area was collected. HE staining, immumohistochemical staining of proliferating cell nuclear antigen (PCNA) and MASSON staining were adopted to observe the morphology of fascial connective tissues, expression of PCNA in cells and arrangement and expression of collagenous fiber.
RESULTSAfter acupuncture in each group, the consistency of morphology of fascial connective tissues and arrangement of collagenous fiber were changed; the expression of PCNA protein in the fascial connective tissue in each group was significantly increased (P<0. 01, P<0. 05). The area distribution of collagenous fiber were changed, and that in the thin needle group was insignificantly increased compared with that in the blank group (P>0. 05), and that in the medium needle group and thick needle group were reduced compared with that in the blank group (both P<0. 05).
CONCLUSIONSAcupuncture with different filiform needles can change the local tissue morphology of acupoints, strengthen cell activity and adjust the exyression of collagenous fiber protein, which may be one of the cellular biomechanics principles of the acupuncture therapy's "regulating meridians" effects. However, the stimulation is produced by different fifiform needles, and the complex relationships exist between cells and collagen fibers.

OBJECTIVETo compare clinical efficacy of anatomic locking plate and Gamma nail in treating unstable femoral intertrochanteric fractures with external wall fractures.
METHODSFrom June 2010 to June 2014,clinical data of 44 patients with intertroehanteric fractures associated with lateral wall fractures (type 31A2.2-3.3) followed more than 12 months,which treated with Gamma nail or anatomic locking plate,were retrospective analyzed. Sixteen patients were treated with anatomic locking plate, including 6 males and 10 females aged from 32 to 83 years old with an average of 56.5 years old. Twenty-eight patients were treated with Gamma nail including 17 males and 11 females aged from 26 to 87 years old with an average of 60.4 years old. Operative time, intraoperative fluoroscopy times, blood loss (intraoperative and hidden blood loss), hospital stays were observed and compared. PPMS and HHS scoring were used to evaluate postoperative clinical effect.
RESULTSAll patients were followed up from 12 to 24 months with an average of 16.2 months. Operative time in Gamma nail was shorter than anatomic locking plate; while blood loss( intraoperative and hidden blood loss) and intraoperative fluoroscopy times in anatomic locking plate were less than that of in Gamma nail. There was no significant meaning in hospital stays between two groups. Postoperative full weight-bearing time in anatomic locking plate was prolonged than Gamma nail. At the final following-up, PPMS in Gamma nail was 7.50 ± 1.78 and 6.82 ± 1.38 in anatomic locking plate, and there was no obvious meaning between two groups (t = 2.341, P = 0.132); there was no significant differences in HHS score between Gamma nail (83.25 ± 11.18) and anatomic locking plate (86.14 ± 12.36) (t = 1.923, P = 0.243). The incidence of complications in Gamma nail was less than anatomic lock-ing plate (P = 0.005).
CONCLUSIONAnatomic locking plate for intertrochanteric fractures with external wall fractures could avoid re-injury of external wall, especially for severe comminuted fractures, difficult for intramedullary nailing, and there was no significant meaning in hip joint function compared with Gamma nail, while postoperative incidence of complications was higher than Gamma nail, so early weight-bearing was not stress.

Objective To describe the clinical features of convulsive status epileptieus (CSE) in our hospital and to provide a basis for future CSE prevention and treatment. Methods Patients with CSE hospitalized from January 1996 to October 2007 were prospectively observed. Logistic regression was used to identify predictors of prognosis. Results All 220 eases of CSE were prospeetively analyzed, a hundred and two patients(46.4%) originated from rural areas. The primary cause of CSE was central nervous system(CNS)infectian (72cases, 32.7%), followed by discontinuation or reduction of antiepileptie drugs (AEDs, 35 cases,15.5%). The median duration of CSE was 5 hours and median duration of seizures before treatment was 2 hours; both were longer in rural patients (7.0 and3.5 hours respectively) than in urban patients (3.0 and 2.0 hours, Z=-3.433,-1.558,both P<0.05). The fatality rate by the time of discharge was 15.9%. Logistic regression analysis showed that the duration of CSE (χ2=20.941), a history of epilepsy (χ2=4.910), and respiratory depression (χ2=16.086) were independent predictors of CSE prognosis (allP<0.05) . Comparisons between these data of USA and Europe were made. Conclusions CSE occurs mostly in rural population and epilepsy patients. CNS infection and withdrawal or reduction of AEDs in patients with epilepsy were important triggers of CSE. Antiepileptic therapy for status epilepticus in China falls behind that in the European countries.
