The clinical data of 8 patients with the fourth-degree laceration of perineum, who were admitted in Beijing Obstetrics and Gynecology Hospital, Capital Medical University from January 2004 to December 2010, were reviewed retrospectively. The causes and clinical strategies were analyzed. The fourth-degree laceration of perineum was mainly caused by improper skills of midwifery, too faster labor,insufficient estimation of fetal-weight and perineal condition and obstetric forceps in this group of patients.Primary suture was performed and all cases achieved complete healing. The improvement of midwifery skill,carefully monitoring the uterine contraction, accurate evaluation of condition of perineum and the fetal-weight and good communication between patients and midwives are the key points to prevent the fourth-degree laceration of perineum.

BACKGROUND: It is believed that repetitive transcranial magnetic stimulation (rTMS) may produce such neurophysiological effects as regulating regional cerebral blood flow, neurotransmitters, local metabolism, and neuronal remodeling after nerve tissue injuries. The prognosis ofischemic stroke is related with the cortical function reconstruction in the ipsilateral and contralateral hemisphere of the lesion. Currently studies have not defined whether rTMS can affect the cortical function, protect ischemic neurons and promote motor functional recovery after cerebral ischemia.OBJECTIVE: To investigate the effects of rTMS on rat motor cortical excitability and neural function in acute stage of cerebral ischemia-reperfusion injury.DESIGN: Completely randomized experiment.SETTING: Electroneurophysiological Laboratory of Peking Union Medical College Hospital.MATERIALS: The experiment was completed in the Zoological Research Center of Peking Union Hospital from January to June 2004. Totally 22adult male healthy Wistar rats were randomly divided into treatment group and the control group with 11 in each.METHODS: After determination of the average motor threshold of the right hind limbs, which was 22% of the maximum output, the rats were subjected to middle cerebral artery occlusion for 1 hour followed by reperfusion for 72 hours. At each time point of immediately and at 12, 36 and 60 hours after the initiation of reperfusion, the rats in the treatment group received rTMS treatment (20 Hz, 40% maximum output, 5 seconds for each session with an between-session interval of 2 minutes for a total of 10 sessions), and the site for motor threshold evaluation was used for rTMS stimulation; the rats in the control group recevied no treatment after model establishment. Motor threshold testing was performed in both groups 4 hours after the last session of treatment to avoid immediate-early effects of rTMS on the motor threshold. At 24 and 72 hours of reperfusion, the scores of neural function were recorded according to evaluation systems. All the rats with scores between 1 and 3 were enrolled in statistical analysis were evaluated between.MAIN OUTCOME MEASURES: ① Motor threshold of the rats in both groups before and after injury; ② Neural function scores at 24 and 72 hour reperfusion; ③ Infarct volume at 72 hour of reperfusion.RESULTS: Totally 13 rats entered the final result analysis. Before injury,motor threshold in the treatment and control group was similar (P=0.71),and after the injury, the motor threshold of the control group was 1.49times that of the treatment group but such difference was not statistically significant [(41.62±24.73)% vs (28.00±9.35)%, t=-1.17, P=0.27]. At 24hours of reperfusion, the functional scores of the treatment group and control group were not significantly different (P=0.46), but at 72 hours, the scores of the treatment group were significantly lower than that of the control group (1.60±1.52 vs 7.75±3.62, t=-3.57, P=0.004). The average infarct volume of two groups was (62.00±60.88) mm3 and (20.00±12.41) mm3 at 72 hours of reperfusion, respectively, which, after logarithm transformation,was not significantly different between the two group (t=-1.31, P=0.22),but when the infarct volume was transformed into Log10 values, a significant difference occurred between them (P=0.045).CONCLUSION: rTMS may stabilize and prevent the increment of the motor threshold, time-dependently relieve the neural function disability and reduce the infarct volume after cerebral ischemia-reperfusion injury.

Objective To analyze the association of DOG1 protein with gastrointestinal stromal tumors(GIST). Methods Seventy-seven patients diagnosed with GIST between January 2005 and June 2010 were enrolled. The DOG1 expression in GIST was determined using immunohistochemistry.The result was compared with that of CD117 and CD34. Results Of 77 GIST patients, the DOG1 was expressed in 74 (96.10%) patients and CD117 in 70 (90. 9%) patients, with no significant difference between DOG1 and CD117 (P>0.05). DOG1 expression was not related to the risk stratification of the tumor, site, age and gender (P>0. 05). Of 7 GIST patients with negative CD117,6 patients were positive for DOG1 expression. Whereas 2 of 3 DOG1 negative patients were positive for CD117 expression. Conclusions DOG1, as a novel marker for GIST,has high sensitivity as CD117. It is a good complementarity in diagnosis of GIST when combine DOG1 with CD117, especially in diagnosis of CD117 negative patients. However, the DOG1 can not be used as an index in eveluating the risk stratification of the GIST.

Objective:To provide policy recommendations for Beijing public health departments to grasp the dy-namic allocation of healthcare resources and the advantage of medical functional dispersal, and making appropriate health policies to rationally adjust the allocation of health resources. Methods:To study the dynamic function of Bei-jing medical, this study uses the method of accounting of cases summary of the annual report on health finance through the descriptive analysis of the gross fixed capital formation in various regional government-run health facili-ties. Results:The results of this study show that the quality of medical health administrative resources was higher, but effectively dispersed in 2015. By contrast, the basic public health resources allocation was unbalanced. Conclu-sion:This study puts forward the corresponding health policy suggestions. On one hand, it is important to make fur-ther policy to encourage high quality medical resources to be effectively relieved and the regional planning should be done according to market demand by avoiding the blind construction at the early stages. On the other hand, much at-tention should be paid on the balanced development of the basic public health service ability and the coordinated de-velopment of administrative capacity in health, and supporting policies should be formulated, which should rationally allocate the public health resources for a better overall medical functional dispersal.
