Objective To explore clinical characteristics of severe pre-eclampsia and eclampsia complicated with reversible posterior leukoencephalopathy syndrome(RPLS).Methods Clinical data of 31 cases of severe pre-eclampsia and eclampsia complicated with RPLS were studied retrospectively.ResulIs These 31 cases with RPLS accounted for 48% of those with eclampsia,.and all presented with hypertension,headache and disturbalice of vision,24 cases with seizure episodes,19 cases with nausea and vomiting and 13 with continuous dysphoria after seizure.Neuroradiologic findings showed edema predominantly in the bilateral posterior cerebral white matter,especially in occipital-parietal lobe,with low density lesions in CT and long T1 and T2 signals in brain MRI. Conclusions Severe pre-eclampsia and eclampsia tended to complicate with RPLS,presenting severe hypertension,headache,disturbance of vision and recurrent seizure as major clinical manifestations.

Objective:To investigate whether the mindfulness training can reduce the aggression level and im-prove the sleeping quality among incarcerated people.Methods:Fifty-four male criminals were recruited into the study.They were divided into mindfulness training group (n =25)and control group (n =29).The training group took mindfulness exercise once a week for 6 weeks.While the participants in waiting list control group waited for 6 weeks without intervention.After 6-week mindfulness training for training group and post-assessment for all partici-pants,the waiting list control group went into 6-week mindfulness training.The Five Facet Mindfulness Question-naire (FFMQ),Aggression Questionnaire (AQ)and Pittsburgh Sleep Quality Index (PSQI)were assessed before and after the intervention.Results:There were 19 valid data in training group,and 21 in control group.After 6-week training,the score difference between pre-and post-assessment of FFMQ (P <0.01 )was higher in the training group than in the control group,and the difference of AQ (P <0.01)and PSQI (P <0.01)was lower in training group than in the control group.Conclusion:The results suggest that 6-week mindfulness training could effectively reduce the aggression level and improve the sleep quality in the long-term incarcerated males.

OBJECTIVETo evaluate therapeutic effects of Rigidfix cross pins combined with Intrafix pins for the reconstruction of anterior or posterior cruciate ligament under arthroscopy.

METHODSFrom January 2009 to June 2010,34 patients with anterior or posterior cruciate ligament injuries were divided into two groups : group A and group B. There were 24 patients in group A, including 19 males and 5 females,with an average age of (31.83±9.57) years old. The patients in group A were treated with anterior cruciate ligament reconstruction under arthroscopy; Rigidfix cross pins and Intrafix pins were used to fix femoral and tibial side respectively. Among the 10 patients in group B, 8 patients were male and 2 patients were female, with an average age of (27.20+7.59) years old. The patients in group B were treated with posterior cruciate ligament reconstruction under arthroscope; Intrafix pins and Rigidifix cross pins were used to fix femoral and tibial side sepectively. The drawer test and Lachaman test were used to evaluate postoperative knee stability. All the patients were followed up at least 18 months. Lysholm and Tegner knee scores were used to evaluate the clinical therapeutic effects.

RESULTSAll the 34 patients were followed up, and the duration ranged from 18 to 26 months,with an average of (20.79±2.39) months. All the patients obtained good pain relief and knee stability. In group A,Lysholm scores significantly increased from 43.04±7.57 preoperatively to 85.41±4.68, 92.50±3.05, and 93.45±2.57 at 6,12, and 18 months postoperatively; Tegner scores significantly increased from 2.62±0.92 preoperatively to 7.45±1.14, 8.58±0.77, and 8.95±0.55 at 6, 12, and 18 months postoperatively. In group B,Lysholm scores significantly increased from 46.20±8.27 preoperatively to 86.40±5.14,90.40±2.67,and 92.00±3.85 at 6,12,and 18 months postoperatively ;Tegner scores significantly increased from 2.00±0.66 preoperatively to 7.10±0.99, 8.60±0.84, and 8.80±0.42 at 6,12, and 18 months postoperatively. There were no differences in Lysholm and Tegner scores between group A and B at different times during follow-up. Lysholm scores of all patients significantly increased from 43.97±7.79 preoperatively to 85.70±4.76,91.88±3.06,and 93.02±3.01 at 6,12,and 18 months postoperatively. Tegner scores of all patients significantly increased from 2.44±0.89 preoperatively to 7.35±1.09, 8.58±0.78, and 8.91±0.51 at 6,12,and 18 months postoperatively. During the follow-up period,there were no serious immunological rejection and complications.

CONCLUSIONReconstruction of anterior or posterior cruciate ligament under arthroscopy with Rigidfix cross pins and Intrafix pins fixation is feasible therapy for anterior or posterior cruciate ligament injuries, and the fixation is rigid. The therapy restores knee stability and provides a satisfactory short-term results.

OBJECTIVETo explore the surgical method and its clinical effects of minimally invasive osteosynthesis on the treatment of complex ankle fractures.

METHODSFrom January 2007 to December 2011, 53 patients with complex ankle fractures were treated with minimally invasive osteosynthesis. There were 31 males and 22 females, with an average age of 38.2 years old (ranged, 18 to 65). According to the system of Lauge-Hansen, 32 fractures were supination external rotation injury (grade WV), 13 fractures were pronation external rotation (grade III or IV), 5 fractures were pronation abduction (grade III); and 3 fractures can not be classified due to serious comminution fracture of fibula. According to the system of Denis-Weber, there were 4 cases with type A, 34 cases with type B and 15 cases with type C. Seven cases were open fractures. The duration from injuries to operation ranged from 2 hours to 14 days with an average of 5 days. The sequence of reduction and fixation of ankle fractures was firstly posterior malleolus, then medial malleolus and lateral malleolus, and inferior tibiofibular syndesmosis lastly. The fractures of posterior malleolus were reduced and fixed through anterior ankle approaches; the fractures of medial and lateral malleolus were percutaneously fixed with bolts or blade plate or tensile force band; and inferior tibiofibular syndesmosis were firmly fixed if necessary. Baird-Jackson scoring system was used to evaluate clinical effects.

RESULTSForty-eight patients were followed up from 10 to 36 months with an average of 13 months. The fractures got healing with an average time of 12 weeks (ranged, 10 to 18). According to the Baird-Jackson scoring system, the mean score of ankle function was 94.7 +/- 4.2, and 28 cases obtained excellent results, 15 good, 3 fair and 2 poor. One case experienced superficial infections and was cured by changing dressings, 2 cases experienced fixed syndesmosis screw breakage.

CONCLUSIONThe surgical method of minimally invasive osteosynthesis can ensure the anatomical join restoration, protect the blood supply of fracture end, rebuild the function of ankle joint, obtain satisfactory clinical results in treating complex ankle fractures.

Objective To investigate the inhibitory effect of adriamycin in combination with hyperthermia on apoptosis and bcl-2 expression in the chronic leukemic cell line K562/AO2 in vitro.Methods The working con- centration of adriamycin against K562/AO2 determined by using methyl thiazolyl tetrazolium(MTT) assay was used to treat the chronic leukemic cell line K562/AO2 in vitro alone or in combination with hyperthermia induced using a hot water bath at 40,41 or 42℃.The inhibitory effect was evaluated by MTT assay.The apoptosis rates and bcl-2 ex- pression of K562/AO2 were determined by flow cytometry.Results The working concentration of adriamycin in the study was defined as its 50% inhibition concentration (IC50).A 60 min session of hyperthermia at 40℃,41℃or 42℃was associated with significant growth inhibition of the cell line K562/AO2.Adriamycin chemotherapy alone and with hyperthermia significantly inhibited the growth of K562/AO2.All treatments significantly increased apoptosis rates and down-regulated bcl-2 expression of the K562/AO2 cell line.Conclusion Adriamycin chemotherapy com- bined with 60 min sessions of hyperthermia showed significant suppression effect on K562/AO2 cell proliferation.The treatment can increase apoptosis rates and down-regulate bcl-2 expression.

PURPOSE: We carried out to determine the effectiveness of trabeculectomy and neodymium:YAG (Nd: YAG) cyclophotocoagulation in eyes with neovascular glaucoma from diabetic retinopathy. METHODS: We retrospectively reviewed medical records of patients who had undergone trabeculectomy or Nd:YAG cyclophotocoagulation from May 1992 to August 1997. RESULTS: The average drop in IOP was 24.6 mmHg in the trabeculectomy group and 17.3 mmHg in the transscleral cyclophotocoagulation group. Success rate was 69.2% in the trabeculectomy group and 21.4% in the transscleral cyclophotocoagulation group. Most common postoperative complication was hyphema (38.4%) in the trabeculectomy group and phthisis bulbi (21.4%) in the transscleral cyclophotocoagulation group. CONCLUSIONS: Trabeculectomy had higher success rate and less serious complications than transscleral cyclophotocoagulation. Transcleral cyclophotocoagulation may be considered as a treatment of neovascular glaucoma in the patients who have severe pain or poor general condition.

Epidermoid tumors rarely occur in the central nervous system. Their incidence among intraspinal canal tumors is even less than 1% in most large series. Epidermoid tumors are generally understood as embryogenic or congenital tumor, however the etiologic importance of previous lumbar punctures in the formation of epidermoids has been also suggested by some papers, and almost confirmed by an extensive literature review and an animal experiment. Recently we have experienced a case of intraspinal epidermoid, which occurred at the same site as a lumbar puncture had been performed to carry out lumbar myelogram. To our knowledge, such a case has never been reported in a scientific journal in Korea yet. In this report we emphasize the importance of using a spinal puncture needle with a stylet in spinal taps, and of considering a lesion in the thoraco-lumbar junction on performing lumbar spine CT scan even in a patient only with lumbar disc symptoms.
