Objective To investigate the effects of continuous invasive mechanical ventilation combined with BAL on COPD patients with respiratory failure. Methods Sixty COPD patients with respiratory failure were divided into BAL and control group randomly. Control group were treated with sputum suction tube to aspire sputum and BAL group treated with BAL. The changes in the indicators were observed. Results The SpO2, airway peak inspiratory pressure and blood gas analysis were improved significantly compared with the control group (P < 0.01). The number of peripheral blood leucocytes and the level of CRP in BAL group were lower than those in control group at the seventh day (P < 0.01). The duration of invasive mechanical ventilation and hospital stay in BAL group was shorter than that in control group (P < 0.01) and there was no severe complication in both groups. Conclusion BALwith continuous mechanical ventilation support are safe and effective and shorten hospitalization time and improve the prognosis of COPD patients with respiratory failure.

Objective To evaluate the possibility of keyhole approaches for surgical treatment of petroclival meningiomas. Methods We retrospectively analyzed our experience in 14 cases with petroclival meningiomas surgically treated from May 2003 to January 2004. Eight tumors involved the upper and middle clivus.five tumors were attached to the entire width of clivus and one tumor involved the middle and lower cilvus. The tumors infiltrated into parasella regions or cavernous sinus in six cases simultaneously. Retrosigmoidal keyhole approach was selected to remove the tumors in 6 cases, and subtemporal keyhole approach was selected in 2 cases,while the combined retrosigmoidal and subtemporal keyhole approaches were applied in other six cases. Results Gross total resections of the tumors were achieved in 8 cases, subtotal resections in 4 cases, large resection in two cases who had recurrent tumors. Postoperatively, neurological intact or unchanged were found in 8 cases. The main surgical complications were mild facial palsy (4 cases) , abducent dificits (3 cases) ,temporary oculomotor nerve dificits (2 cases),and lower cranial nerve palsy (1 case). One patient died from disseminated intravascular coagulation (DIC) two weeks after surgey. There were no CSF leakage and infections after surgery in all cases 11 to 19 months follow-up studies demonstrated the great improvement of the Ⅲ and Ⅶ nerve deficits,but minor improvement in the Ⅵ nerve deficits. Conclusion According to the location and extension of the tumors, retrosigmoidal or subtemporal keyhole approaches or their combined can be selected for surgical treatment. These keyhole approaches can expose sufficiently the petroclival region, shorten the surgical time, and minimize the complications. Combined usage of minimally invasive techniques including the keyhole approach and radiosurgey in the treatment of the petroclival meningiomas is suggested.

Objective To investigate the expression of tumor suppressor gene p16~(INK4A) in mouse endometrium during the estrus cycle and early pregnancy and its possible role in blastocyst implantation. Methods Reverse transcription polymerase chain reaction(RT-PCR) was used to detect the expression of p16~(INK4A) mRNA,immunohistochemistry and Western blotting were applied to detect p16~(INK4A) protein in mouse endometrium tissues during the estrus cycle and early pregnancy. Results The intensity of p16~(INK4A) mRNA expression in mouse early pregnancy was higher than that in the estrus cycle.Compared with the other 3 stages, the level of p16~(INK4A) mRNA expression at estrus was obviously higher. During the early pregnancy, the level of p16~(INK4A) mRNA expression increased steadily from day 2 to day 5,reaching the maximal level on day 5,then decreasing. Both immunohistochemical and Western blotting analysis showed the same results in expression patterns of p16~(INK4A) protein for mouse endometrium tissues as those results of RT-PCR.Conclusion p16~(INK4A) is involved in the embryos penetrating into the endometrial barrier.

BACKGROUND: Exogenous neural stem cells (NSCs) can repair nerve and promote recovery of neurofunction following cerebral hemorrhage.OBJECTIVE: To observe the growth and development of NSCs in vitro, to evaluate the survival, migration and differentiation of transplanted NSCs surrounding hematoma and the possible recovery function of NSCs, and to investigate the repairing effect of NSCs on damaged neurofunction in cerebral hemorrhage model rats.DESIGN: Completely randomized grouping design and controlled animal study,SETTING: Department of Neurosurgery, Huashan Hospital, Fudan University.MATERIALS: Eighteen adult healthy male SD rats weighing 280-320 g were provided by Shanghai Animal Center of Chinese Science Academy. BrdU was provided by Neomarkers Company; rat-anti-glial fibrillary acidic protein (GFAP) and rabbit-anti-microtubule-associated protein-2 (MAP-2) by Chemicon Company.METHODS: This study was performed at the Laboratory of Anatomy and Histology & Embryology, Shanghai Medical College,Fudan University from February to December 2006. The NSCs was isolated, cultured, and evaluated from hippocampus of day E14fetal SD rats. Eighteen rats were randomly divided into control group, PBS group and NSC transplantation group. Cerebralhemorrhage rat models were established via injection of autoiogous arterial blood in caudate nucleus. Thirty minutes after model establishment, 5 μ L NSC suspension with the concentration of 2×1011 L-1 was transplanted at four points surrounding hematoma cavity in the NSC transplantation group. Transplantation of PBS and NSCs was the same as autoblood transplantation. Thirty minutes after model establishment, injuries at the four points were performed, and nothing was injected in the control group.MAIN OUTCOME MEASURES: Neurofunction was evaluated with forward limb scale and turning scale just soon after transplantation and at 1, 3, 5, 14, and 28 days after transplantation. Brain was colleted by anesthesia 28 days after model establishment.Differentiation of transplanted NSCs was detected through testing GFAP, MAP-2, and BrdU by using immunohistochemistry.RESULTS: ①Neurofunction scores: There was no significant difference 5 days after model establishment (P>0.05). However, the scores were significantly improved in the NSC transplantation group 14-28 days after model establishment (P<0.05).②lmmunofluorescent double labeling: Apoptosis ceils around hemotoma in the NSC transplantation group were less than those in the PBS group. BrdU and MAP-2 or GFAP-positive ceils were observed in cerebral tissue sections, and this suggested that NSCs could survive, migrate and differentiate in host brain and differentiate into neurons or astrocytes.CONCLUSION: NSC Transplantation contributes to the recovery of neurofunction in cerebral hemorrhage rats through differentiation into neurons or astrocytes.
