Henoch-Scholein purpura(HSP)is a common systemic vasculitis of the small vessel in children,with a variety of clinical manifestations.The main diagnostic criteria include palpable skin purpura.Patients who have gastrointestinal tract as the main symptoms suffer clinically abdominal pain and gastrointestinal bleeding,they are easily misdiagnosed before skin purpura,the rate of misdiagnosis can be as high as 87.5%,and the main treatment is early application-oriented glucocorticoids.This review include etiopathogenisis,pathogenesis,pathology,clinical manifestations,auxiliary examination and treatment about gastrointestinal manifestations in HSP.

Objective To investigate the auditory brainstem response (ABR) of newborns in the neonatal intensive care unit (NICU) after hear screening failure.Methods To test ABR of 833 healthy newborns with no perinatal diseases at the clinic,and 425 newborns born in NICU who failed the hearing screening of monaural or both-ear from March 2014 to May 2015.Results 49.6% of children′s wave V response thresholds were ≥30 dB in the NICU group and 36.1% children′s wave V response thresholds were ≥30 dB in healthy group.The hearing abnormality rate of the NICU group was significantly higher than that of the healthy group(P<0.05);The average auditory thresholds healthy of the group[(19.76±6.59)dB] was significantly lower than those of the NICU group[(41.52±20.35)dB](P<0.05);both ear latency for waves Ⅰ,Ⅲ and Ⅴ and interpeak latency for waves Ⅰ-Ⅴ in healthy group were significantly shorter than those in NICU group (P<0.05).Conclusion The hearing loss extent of the NICU group is greater than that of the healthy group.The ABR abnormality reflects auditory pathway is abnormal.

Objective To explore the curative effect of microsurgery via posterior approach through the sigmoid sinus in the treatment of secondary trigeminal neuralgia. Methods Clinical data of 37 cases of trigeminal neuralgia secondary to cerebellopontine angle (CPA) tumor from October 2000 to July 2006 were studied, including 18 cases of cholesteatoma, 8 cases of meningoma, 6 cases of acoustic neuroma, and 5 cases of trigeminal schwannoma. All tumors were removed with microsurgery through a posterior approach by way of the sigmoid sinus. Results A total resection was achieved in 23 cases, a subtotal resection in 10 cases, and a partial resection in 4 cases. Symptoms of neuralgia disappeared in 35 cases (including 32 cases of immediate relief and 3 cases of relief 2 months after operation). There was no improvement in 2 cases. Conclusions Microsurgery via posterior approach through the sigmoid sinus in the treatment of secondary trigeminal neuralgia is safe and effective.

Objective To investigate the expression of extracellular signal regulated kinase(ERK) in human gastric cancer and evaluate the relationship between ERKs protein level and clinicopathological parameters. Method Western blot was used to measure the activity and expression of ERK 1 and ERK 2 proteins and immunohistochemistry was used for localization in 42 gastric cancer patients.Results ERK 1 and ERK 2 protein levels increased in gastric cancer tissues in comparison to normal tissues ( P 0 05). Expression of ERK 1 and ERK 2 showed a positive linear correlation (r=0 550, P

Objective To present the preliminary clinical results of anterior thoracoscopic correction for thoracic idiopathic scoliosis and consider its ind ications. Methods Between June 2002 and May 2003, 8 female patients with a diagn osis of right thoracic idiopathic scoliosis were selected to undergo thoracoscop ic instrumentation, correction and fusion using Eclipse system. The average age at surgery was 14.8 years (ranged from 13 to 16 years). The average preoperative Cobb angle was 54? (ranged fom 40? to 72?). 5 had idiopathic thoracic curves of King type Ⅲ, 2 of King type Ⅱ, and 1 of King type Ⅴ. The Risser sign rang ed from (+++) to (++++). The bending films of the thoracic curves showed a flexi bility of 60%-75%. The thoracic sagittal profiles remained normal without obviou s kyphosis or lordosis. In all cases the rotation of the top vertebra of scolios is was of degree Ⅰ. The operative time, blood loss, postoperative drainage, the number of instrumented levels, curve correction and loss of correction were ana lyzed. Results The instrumented levels were from T5 to T12. The average number o f instrumented levels for each patient was 7.4. The operative time averaged 6 ho urs. The blood loss during surgery averaged 629 ml (ranged from 400 to 800 ml), with no blood transfusions being required, except in one case. The average posto perative drainage was 500 ml. The postoperative Cobb angle was 15? on average w ith curve correction of 74%. With an average follow-up period of 6.5 months (ran ged from 3 to 12 months), the loss of correction averaged 8.3%. No hardware comp lications occurred. Conclusion Compared to the open anterior and posterior surge ry, the thoracoscopic Eclipse instrumentation is a safe and an effective way to correct thoracic idiopathic scoliosis with similar short-term postoperative resu lts. However, challenging issues remain. These included long operative time, hig h technical requirement, relatively limited indication and large radiation expos ure. Again, further research is needed to study its long-term impact.

0.05). Conclusion Thoracoscopic anterior spinal release have comparable clinical results as conventional thoracotomic release for AIS patients.

0.05). Conclusion There exist radiological changes in paravertebral muscles in AIS, which may be secondary to AIS and have potential clinical importance on the evaluation of curve progression.
