Objective To research the important of prenatal diagnosis and effect of intervention to fetal hydrothorax. Methods The cases of fetal hydrothorax (n=5) were obtained from the Shengjing Hospital,China Medical University between December 2014 and May 2015. All pregnancies were uncomplicated, excluded congenital organic and chromosomal abnormalities during prenatal diagnosis and with a 37 average gestational weeks. The case 1, 2, 4 were unilateral hydrothorax and the case 3, 5 were bilateral. We performed an antenatal thracocentesis to case 1, 2, 3. In case1, the hydrothorax increased rapidly after 5 days, and the patient underwent a cesarean section and ex utero intrapartum treatment (EXIT);in case 2, the fetal heart rate was decreased to 40-50 bpm suddenly during thracocentesis, and we performed an emergent cesarean section and EXIT for the patient; in case 3, the patient underwent thracocentesis and a meanwhile cesarean section and EXIT procedure. We performed a conservative management to case 4, 5, the hydrothorax resolved spontaneously during the pregnancy and after birth, both patients underwent cesarean section. Results All fetuses were survived, the neonates of case 1, 2 and 3 underwent assited mechanical ventilation, thoracic close drainage, then discharged after hydrothorax resolved and feeding tolerance;in case 4, there was no respiratory distress and hospital treatment;in case 5, the neonate underwent assited mechanical ventilation and conservative management, the hydrothorax has resolved gradually. Conclusions The prenatal diagnosis and antenatal intervention (thracocentesis) may play an important role in fetal hydrothorax treatment. In clinical, we should choose different plan according to the gestation weeks and classification of hydrothorax of the patient.

Objective To discuss the methods and outcomes of twin reversed arterial perfusion sequence in different stage. Methods From August 2012 to December 2013, 11 cases were diagnosed with twin reversed arterial perfusion sequence (TRAP) by 3d color Doppler ultrasound in the Maternal ang Fetal Medicine Center ,Affiliated Shengjing Hospital, China Medical University, including 3 cases in stageⅠa, 7 in stageⅡa and 1 case in stageⅡb. We performed expected therapy to 3 cases in stageⅠa and 4 cases in stageⅡa [1 case (case 9) in stageⅡa developed to stageⅡb and was terminated by emergency cesarean section], radio frequency ablation (RFA) selective reduction to 3 cases in stage Ⅱa, emergency cesarean section to 1 case in stageⅡb. All cases except case 1,4 took cesarean section to terminate pregnancy and would be followed up on the aspect of infant′s growth. Results (1) 3 cases in stageⅠa were monitored by sequential ultrasound examination, all donors grew normally, in which 2 acardias arised spontaneous cessation of flow and were implemented of cesarean section after the normal period of gestation; 1 case suffered premature rupture of membrane and experienced the natural childbirth at 34 gestation weeks plus 5 days. The survived average labor weight was 2 923 g. (2) In the 7 stage Ⅱa cases, 3 cases were implemented of RFA selective reduction, 2 cases survived and the average labor gestation was 35 weeks plus 1 day and average labor weight was 2 050 g;in 3 expected therapy cases, 1 case suffered premature rupture of membrane at 34 gestation weeks plus 5 days and experienced cesarean section; 1 case was observed for 3 weeks and the donor was stillborn; 1 case progressed to stage Ⅱb and experienced cesarean section at 34 gestation weeks plus 5 days;and 1 case was lost of follow up. (3) For 2 cases of stageⅡb cases, one was progressed from stage Ⅱa during expected therapy; the other one had been already in stage Ⅱb since visiting and experimented an emergency cesarean section, but the neonate died of heart failure two days after labor. (4) 7 survived neonates were followed up, all had a normal condition compared to kids of the same age, except one suffering a congenital heart disease, patent ductus arteriosus and atrial septal defect and whose weight (6 kg at 7 months) was lighter. Conclusions We should make the diagnosis of TRAP as early as soon and choose appropriate therapy according to the stage. According to our research, cases in stage Ⅰa can undergo an expected therapy under a sequential ultrasound examination;cases in stageⅡa can undergo a RFA selective reduction to improve the prognosis of the donor, which can make a good perinatal outcome.

Objective: To assess the clinical features, diagnosis and treatment of gastrointestinal stromal tumor in the rectum.Methods: Records of 18 patients diagnosed as GIST in the rectum between January 2002 and April 2009 were re-viewed and the major clinical features, treatment modalities and outcomes were analyzed.Results: The clinical features of GIST in the rectum were nonspecific.Most patients manifested with bloody stool or changes in bowel habits.CT scan or MRI findings showed necrosis and/or hemorrhage in the tumor and well defined tumor margins.Even in the case of large GIST, no lymphadenopathy was not found, which could be a factor for the differential diagnosis of GIST from other rectal neoplasms.All of the resected tumor specimens showed positive expression of CD117 and CD34 in immunohistochemical staining.Low and very low risk patients accounted for 44.4% (8/18).All patients received surgery.Twelve patients were treated with local excision with different approaches.Anterior resection of the rectum (Dixon) was undertaken in three pa-tients and abdominoperineal resection (Miles) in three patients.Neoadjuvant therapy with imatinib was applied for three pa-tients with partial response.After a median follow-up of 34 months (1~84 months), recurrence and/or metastasis occurred in five patients, and three of them were treated with imatinib.One patient received Miles surgery after repeated local exci-sions.Only one patient died of bone metastasis.Recurrence-free survival (RFS) of the local excision group was longer than that of abdominoperineal resection (APR) group (75.0±8.4 months vs 26.0±11.1 months, P=0.023).Conclusion: The treatment for rectal GIST should be individualized and be different from that of rectal cancer.Treatment decision and choice of procedures should be based on careful preoperative evaluation of tumor size, location, extent and risk level.Most of the anorectal GIST were rated as low-risk in this cohort and could be excised locally by different approaches with satisfactory outcome.Neoadjuvant therapy with imatinib may benefit some patients to obtain the opportunity of sphincter-saving.

Objective To characterize the clinical manifestations and to evaluate the value of the electrophysio-logical examination in patients with peripheral nerves injuries caused by neurobrucellosis. Methods Electrophysiology examination was conducted in 32 patients with peripheral nerve injuries caused by neurobrucellosis and 32 normal controls who had equivalent age and gender. The results were further statistically analyzed. Results There were sig-nificant difference between patients and healthy control group in distal motor latency (DML), compound motor active potentials (CMAP) amplitude, motor nerve conduction velocity (MCV), sensory nerve action potential latency(SL),senso-ry nerve action potential (SNAP) amplitude and sensory nerve conduction velocity (SCV) ( P﹤0.05). Electrophysiology examination revealed peripheral nerve damage of limbs involving, both sensory nerve and motor nerves, of which sen-sory and motor nerve injuries accounted for 55.47% and 16.80%, respectively. Median and sural nerve injuries were most frequently affected in upper (64) and lower limbs (16). Motor and sensory nerve conduction velocity was delayed in 43 nerves (16.80%) of 256 examined motor nerves and in 142 nerves (55.47%) of 256 examined sensory nerves. The damage of the sensory nerves was more severe than those of the motor nerves and damage of nerves in the upper limbs was more severe than those in the lower limbs. Conclusion Electrophysiologoical examination provides objective basis for the diagnosis of peripheral nerve injuries in neurobrucellosis.

The shape and structure of granules are controlled by the granulation process, which is one of the main factors to determine the nature of the solid dosage forms. In this article, three kinds of granules of a traditional Chinese medicine for improving appetite and promoting digestion, namely, Jianwei Granules, were prepared using granulation technologies as pendular granulation, high speed stirring granulation, and fluidized bed granulation and the powder properties of them were investigated. Meanwhile, synchrotron radiation X-ray computed micro tomography (SR-µCT) was applied to quantitatively determine the irregular internal structures of the granules. The three-dimensional (3D) structure models were obtained by 3D reconstruction, which were more accurately to characterize the three-dimensional structures of the particles through the quantitative data. The models were also used to quantitatively compare the structural differences of granules prepared by different granulation processes with the same formula, so as to characterize how the production process plays a role in the pharmaceutical behaviors of the granules. To focus on the irregularity of the particle structure, the box counting method was used to calculate the fractal dimensions of the granules. The results showed that the fractal dimension is more sensitive to reflect the minor differences in the structure features than the conventional parameters, and capable to specifically distinct granules in structure. It is proved that the fractal dimension could quantitatively characterize the structural information of irregular granules. It is the first time suggested by our research that the fractal dimension difference (Df,c) between two fractal dimension parameters, namely, the volume matrix fractal dimension and the surface matrix fractal dimension, is a new index to characterize granules with irregular structures and evaluate the effects of production processes on the structures of granules as a new indicator for the granulating process control and optimization.

Objective To compare the effect of various manipulation of Tuina on surface electromyogram (sEMG) in hemiplegics after stroke. Methods From January to May, 2016, 20 inpatients with hemiplegia after stroke accepted Tuina on bilateral rectus femoris by the same therapist, with the techniques of rolling, patting, rubbing, shaking, kneading and pressing, one minute a manipulation and interval one minute. Integrated electromyography (iEMG), root mean square (RMS) and median frequency (MF) of sEMG were compared, both in rest and during Tuina. Results There was no significant difference of iEMG, RMS and MF between affected and unaffected sides in rest (t<1.147, P>0.05). iEMG and RMS were the most under patting (F>21.376, P<0.001), and MF was the highest under pressing (F>11.772, P<0.001). iEMG, RMS and MF were not very different under other manipulation (P>0.05). iEMG and RMS were less in the affected side than in the unaffected side under patting (P<0.05). Conclusion Various manipulation of Tuina may be different in neuromuscular stimulation, that patting may stimulate more muscles and motor units.
