Objective To study the effect on aiding treatment of patients with dysmenorrhea through psychological intervention.Methods Sixty patients with dysmenorrhea were randomly divied into the intervention group and the control group with 30 cases in each group.The contrd group were treated with allopathy and normal care.On the base of such ineasures,the intervention group were treated with psychological interventions like congnitive regulation,emotion regulation and behavioral regulation.Results The average pain degree of the control group was Ⅱ-Ⅲ.The average pain degree ofthe intervene group Was Ⅰ-Ⅱ.The results ofthe two groups were eonpred.P＜0.01 and the difference was significant.The average dose of Atuopin in the control group was 0.60mg.and the average dose of Atuopin in the intervention group was 0.43 mg.P＜0.01 and the difference of the two groups is obvious.The average time being in bed in the control group was 5.85 hours,and the average time beingin bed in the intervene group was 3.2.5 hours.The results of the two groups were compared,P＜0.01and the difference is significant.Conclusion The intervention can apparently improve patients' symptoms of pain.

Objective To summarize the outcome of volar approach for unstable distal radius fractures, as well as to explore and discuss the more prompt and efficient way with less complications. Methods Volar approach was used for unstable distal radius fractures in 129 cases (140 sides). This study involved 77 males and 52 females with an average age of 43.7 years (range, 15-76 years). According to the Coony universal classification, 36 sides were of type Ⅱ, 7 of type Ⅲ and 97 of type Ⅳ, which included 105 sides of fresh fracture and 35 old ones. Extra-articular reduction was performed under C-arm to restore the palm tilted angle and ulna deviated angle. For those with severe bone defect, artificial bone graft or auto-graft was applied. T-plates were fixed in 32 sides, T-plates with K-wires in 57, external fixators in 13, external fixators with K-wires in 38 respectively. Results The functional recovery was achieved at 3.8 months averagely after operation with a range of 2 to 6 months. The mean follow-up period was 23.6 months ( range, 12-40 months). 91 sides were rated as excellent, 38 as good, 10 fair and 1 poor. The long-term excellent-good rate was 92.1%. Conclusion The volar approach for unstable distal radius fractures has the following advantages: 1)less invasive without compromise to the bone and tendon sheath of distal radius; 2)The volar surface of radius is smooth , easier for plating; 3)no injury to the palmer ligaments and better for recovery; 4)better reduction; 5)avoidance of bone graft displacement; 6) shorten the operation time, less post-operative complication, earlier rehabilitation and faster functional recovery. The volar approach for unstable distal radius fractures is suitable either for internal or external fixation.

Traction during reduction is essent ial for internal or external fixatio n of unstable distal radial fractures.Adequate and effective t raction is the key to the restoration of articular congruence,normal joint relation and the length of distal radius.The f orearm traction instrument develop ed by the authors is a simple,versatile and reliable device,from which stable,continuous and effective traction c an be expected during the surgery.The traction instrument is connected wi th the surgery-table before the operation.According to the needs of diff erent operations,many kinds of traction could be perfo rmed to support the operation.With t he help of the device,frac-ture reduction and fixation is signi ficantly improved during the surgery without excessively violent traction.The X-ray exposure and the operation hou rs can also be decreased as well.Over-traction or long-time violent traction could be avoided during the surgery.According to the author' s experience,the forearm traction i nstrument is an effective implemental device in the treatment of the unstable fractures of distal radius.[

Objective To evaluate the treatment of unstable fractures of the distal end of the radius with external fixator.Methods 28 patients with unstable fractures of the distal end of the radius were treated with external fixators. 19 cases of them were fixed with K wires and bone graft was used in 4 patients with severe bone defect.Results The patients were followed up for an average period of 10.11 months. According to modified Mcbride grading, 25 patients showed excellent or good results with the excellent and good rate being 89.28% . Conclusion It is difficult to reduce unstable fracture of the distal end of the radius with close reduction. Redisplacement is frequent for plaster cast and is not reliable in maintaining reduction. These fractures should be treated with early open reduction. External fixation plus reasonable exercises taken after the operation is one of the good treatments and good results can be predicted. The most important factors affecting final outcome include radial shortening and reduction of articular surface.

Objective To determine the effects of endogenous testosterone on early atherosclerosis of coronary artery in castrated rabbits fed with high fat diet.Methods 30 adult male New Zealand white rabbits were randomly allocated to three groups:castrated group,physiological level group [6mg/kg intramuscular injection of testosterone undecanoate(TU)after cas tration,once every two weeks] and sham operation group.All animals were fed with high fat diet,but only the animals in both castrated group and physiological level group were castrated(bilateral castration)reproduce models with different testosterone levels.Serum total testosterone and estradiol,serum lipids and lipoproteins were determined 12 weeks after model establishment.The intimal thickness of coronary and kidney artery were measured and analyzed.Results The average level of serum TC,TG,LDL-C,ApoB,LDL-C/HDL-C and ApoB/ApoA1 were higher in castrated group than in sham operation group and physiological level group(P0.05).Conclusion The decrease in endogenous testosterone provokes early atherosclerosis of coronary artery in male rabbits fed with high fat eiet.

Objective To investigate the effect of variation of cesarean sections during labour and their indications on the total cesarean section rate. Methods A total of 458 cases of cesarean section was selected from January to June of 1990,1996,2002. They were divided as indication group and no indication group. The change of the indication and cesarean section rate was compared. Results The ratio of cesarean section during labour in total cesarean sections rised. The ratio was 22.0%, 20.8% and 39.4% in 1990, 1996 and 2002 respectively. The proportion of no indication surgery in 2002(63.37%) showed significant growth as compared with that of 1990 (33.84) and 1996 (32.58). Of all cases of cesarean section having indications, the rate of trial produce failure increased in 2002 (25.81%) while it was 11.45% and 16.67% in 1990 and 1996 respectively. The rate of fetal distress decreased from 25.19% (1990), 21.67% (1996) to 12.90% (2002). Conclusion Ascen ding of cesarean section rates during labour was an important factor that increased cesarean section rate in recent years. To decrease the total rates of cesarean section, many important measures should be done such as paying more attention to social factors, reinforcing propaganda and maternal health care , encouraging spontaneous vaginal delivery, emphasizing company during labour and analgesia or pain free delivery, laying stress on the management and monitoring during first stage of labour as well as psychological care.

ObjectiveTo investigate the correlation between the interpersonal trust and coping modes in aged patients with coronary heart disease (CHD).MethodsA total of 246 aged patients with CHD at home and in hospital were tested on their interpersonal trust and reply modes by adopting the Interpersonal Trust Scale (ITS) and Medical Coping Modes Questionnaire (MCMQ).ResultsThe interpersonal trust level of patients with higher educational background was significantly higher than those with poor educational background ( P<0.05). The patient's interpersonal trust was significantly positive correlation to the confrontation coping mode ( r=0.388, P=0.000) and significantly negative correlation to the compromising coping mode ( r=-0.434, P=0.000), but was not significantly correlation to avoidance coping mode ( P>0.05).ConclusionThe interpersonal trust of aged patients with CHD can influence their choice of coping modes.

Objective To evaluate different measurement methods in histogram for the diffusion and perfusion parameters from intravoxel incoherent motion (IVIM) MR imaging of different types of uterine fibroids.Methods 63 patients with confirmed uterine fibroids (80 in total) were examined with MR imaging.3D T2WI and IVIM imaging were performed for those patients.The fibroids were classified into three types (type 1, 2, 3) on the basis of different signal intensities on T2WI according to Funaki's theory.Real diffusion coefficient (D), pseudodiffusion coefficient (D*) and perfusion fraction (f) were calculated using IVIM analysis.25%,50% and 75% of those parameters (D25,D50,D75,D*25,D*50,D*75,f25,f50 and f75) as well as mean values (Dmean,D*mean and fmean) were calculated using histogram method.ANOVA was used to compare the IVIM parameters among the three types of fibroids.Results There were 44 type 1,24 type 2 and 12 type 3 fibroids in the total of 80 fibroids.There was significant difference among all the diffusion parameters from histogram and mean values of different types of fibroids, and only one perfusion parameter D*75 value showed significant difference (P<0.05).There was no significant difference among all the f values from histogram and mean values.Conclusion Different measurements of parameters from IVIM histogram showed no added value for diffusion features in different types of fibroids compared to mean value.While the perfusion parameter D*75 value from histogram can distinguish the features of perfusion within different types of fibroids compared to mean value.

Objective To investigate the clinical manifestations and prognosis of infants less than three months with kawasaki disease (KD).Methods Clinical manifestations,diagnosis,treatment and follow-up of the infants less than 3 months diagnosed with KD and hospitalized from Jan 2009 to Jan 2012 in Capital Institute of Pediatrics were collected and reviewed.Results Fourteen infants less than 3 months were diagnosed as KD during recent 3 years.Among them 8 cases were diagnosed as typical KD,6 cases as incomplete KD.The infants with KD had clinical features as fever longer than 5 d (14/14),cervical lymphadenopathy (11/14),rash (11/14),extremity changes (9/14),mucositis (10/14),conjunctivitis (5/14).Infants with incomplete KD had fever longer than 5 d (6/6) and extremity changes (4/6),cervical lymphadenopathy (3/6),rash (3/6).But fewer infants (2/6) had extremity changes later than 2 weeks.It was difficult to diagnose atypical KD earlier.More than half (8/14) of all the infants with KD had complications,6/14 had damaged liver function.Nearly all the cases (12/14) received intravenous immunoglobulin 1 g/.(kg·d) within 10 d of presentation.The coronary artery lesion was found in 2 infants during hospitalization.2 cases were found to have CAL during the follow-up after discharge from the hospital.The coronary artery lesion of the 4 infants recovered during follow-up.Conclusion Infants less than 3 months have higher rate of incomplete KD.All infants with KD should be followed-up and monitored for the coronary artery lesion.

Objective:To investigate the anesthetic choice for patients undergoing cesarean section complicated with placenta implantation.Methods: A retrospective case review of the patients with placenta implantation between 2008 and 2013 at Peking University Third Hospital was conducted in the International Classification of Diseases (ICD)-9 codes,excluding natural birth and not first diagnosed in our hospital,a total of 96 cases were incorporated into this study.According to the degree of implantation,they were divided into three groups: accreta group,increta group and percreta group.We analyzed the time from the start of surgery to baby delivery and the anesthetic technique.Results: The accreta group included 49 cases,the increta group 33 cases,and the percreta group 14 cases.The average time from the start of surgery to fetus delivery in the three groups were (6.7±3.0) min,(7.2±4.6) min,and (11.9±4.9) min,and the percreta group was significantly different from the accreta group and the increta group (P<0.05).There were significant differences among the three groups in anesthetic choices (P<0.001): in the accreta group,45 cases (91.8％) underwent spinal anesthesia,2 cases (4.1％) underwent general anesthesia,and 2 cases (4.1％) were converted to general anesthesia after spinal anesthesia during the operation;in the increta group,22 cases (66.7％) underwent spinal anesthesia,4 cases (12.1％) underwent general anesthesia,and 7 cases(21.2％) were converted to general anesthesia after spinal anesthesia;in the percreta group,2 cases (14.3％) underwent spinal anesthesia,2 cases (14.3％) underwent general anesthesia,and 10 cases (71.4％) were converted to general anesthesia after spinal anesthesia.Conclusion: Spinal anesthesia can be used as the first choice of cesarean section complicated with placenta implantation and general anesthesia should be considered in placenta percreta.
