A total of 1140 medical workers from 8 public hospitals of secondary and tertiary levels in Anhui were surveyed with questionnaire. Their knowledge of the reform, acknowledgement of key points of the reform, desire of participating in the reform and other factors that may influence the reform were investigated as categorized by their hospital, position, title and age. This study comes up with such recommendations as reinforcing communications on public hospital reform, reforming the compensation mechanism to clarify government responsibilities, probing into a better model for multi-institution practice of certified physicians, and encouraging private capital to participate in medical service while ensuring its non-profit nature, and improving the performance appraisal mechanism to ensure incentives of medical workers. These recommendations aim to enable the health administrators in their decision making.

Meningomyelocele combined with squamous cell carcinoma is rare in literature. In this article,we report the clinical and treatment of a patient with meningomyelocele and squamous cell carcinoma and discuss its mechanism,clinical feature,therapy and prognosis.The patient was a 11-year-old Chinese boy.At the time of his birth he was noted to have a lumbosacral meningomyelocele,which was disrupted and the cerebral spinal fluid flew out when the child was six.The wound surface abrased and exudated repeatedly.Two months before admission,the meningomyelocele was disrupted again and the condition got worse.Inspection showed a meningomyelocele in the lower lumbar region 10 cm in diameter,consisting of a cauliflower-shaped swelling and a central crater containing black slough.The area smelled foul and was constantly draining serosanguineous fluid.Magnetic resonance imaging showed meningomyelocele associa-ted with spinal dysraphism and tethered cord syndrome.After thorough preparation,operation was undertaken.A perpendicular skin incision,which was carried down to the lumbar aponeurosis,allowed the main bulk of the tumour to be undercut and removed.The quick frozen pathological examination confirmed that it was squamous cell carcinoma.The skin and subcutaneous tissue were fruther resected and the vertebral canal explored until frozen section showed the excision edge was clear.Skin closure was achieved by a bi-pedicle advancement flap,some 10 cm wide and the secondary defect was closed with a thigh skin graft.Histological examination showed that the massive outgrowth was a well-differentiated squamous cell carcinoma.The postoperative recovery was uneventful and the wounds healed by primary intention.Although meningomyelocele combined with squamous cell carcinoma is rare in literature,the possibility of can-cerization should be considered when there is a long-term and non-healing ulcer (Marjolin ulcer) with foul smell in a meningomyelocele patient.

BACKGROUND: Studies have demonstrated that hyperpolarization-activated andcyclic nucleotide-gated cation channels (HCN) 2 and HCN4 are abnormal expressed in ventricular muscle following heart disease, which is closely correlate to ventricular arrhythmia. Bone marrow stem cells (BMSCs) transplantation can improve damaged cardiac muscle; however, its effect on remodeling of ion channel is unclearly. OBJECTIVE: To detect the changes of HCN2 and HCN4 expression in left ventricle following BMSCs transplantation.METHODS: Five Sprague-Dawley (SD) rats, aged 3 weeks, were prepared for BMSCs by Percoll method. Additional 30 health, male, SD rats, were randomly divided into DMEM, cell transplantation, sham operation and control groups. At 4 weeks after model preparation, DMEM culture medium was injected into the infarcted area and surroundings with 5 points in the DMEM group. The 3rd generation of cultured BMSCs (200 μL, with 5×10~6 cells) were injected into rats in the cell transplantation group with the same methods. The mRNA and protein expression of HCN2 and HCN4 gene was detected by RT-PCR and Western blot respectively.RESULTS AND CONCLUSION: In non-infarcted region, the mRNA and protein expression of HCN2 and HCN4 among each groups had no significant difference (P > 0.05). Compared with the control and sham operation groups, mRNA and protein expression of HCN2 and HCN4 in surrounding of the infracted region was elevated in the DMEM group (P < 0.05), which was greater than that of the cell transplantation group (P < 0.05). The mRNA and protein expression of HCN2 and HCN4 was smaller in the center area of infracted region in the DMEM group than that of the control and sham operation groups (P < 0.05), which was similar to the cell transplantation group (P > 0.05). Acute myocardial infarction can increase mRNA and protein expression of HCN2 and HCN4 in infracted region surrounding. BMSCs transplantation may lower the fatality rate of ventricular arrhythmia by reducing HCN2 and HCN4 expression.

The present study was to examine the effect of stellate ganglion block (SGB) on bilateral regional cerebral oxygen saturation (rSO2) and postoperative cognitive function. Eighty patients undergoing selective coronary artery bypass graft with cardiopulmonary bypass (CPB) were randomly and equally divided into two groups. The patients in group S were given right SGB with ropivacaine, while the patients in group C were injected with normal saline. We compared the bilateral rSO2 after SGB. Minimum Mental State Examination (MMSE), Visual Verbal Learning Test (VVLT), and Digital Span Test (DST) were applied to observe the effect on cognitive function. We found that the incidence of postoperative cognitive dysfunction (POCD) 7 days after surgery in group S was lower than that in group C. The level of blocked side rSO₂ of S group were significantly higher before CPB time of rewarming than that before SGB (P < 0.05), much higher than corresponding non-blocked side rSO₂ before CPB (P < 0.05), and much higher than rSO₂ level in group C before CPB and after CPB (P < 0.05). The non-blocked side rSO₂ in group S before anesthesia were much lower than basic levels and those in group C (P < 0.05). It could be concluded from the above results that there was significant increase in the blocked-side rSO₂ compared to the non-blocked side and there was significant decrease in the incidence of POCD compared to the control group after SGB.

Objective To investigate the potential effect of Lactobacillus acidophilus (L. acidophilus) on prevention and treatment of neonatal mice infected with human rotavirus (HRV). Methods Sixty 4-day-old kunming mice were randomly divided into control group. HRV infected group, L. acidophilus pretreated group (treated before HRV infection ) and L. acidophilus treated group(treated after HRV infection). The manifestation and pathological changes in small intestine of neonatal mice were observed. The HRV antigen in the feces and intestines were measured by ELISA and fluorescent-focus assay, respectively. Results The severity and duration of diarrhea as well as mortality in L. acidophilus pretreated group and treated group were lower than those in HRV infected group. The duration of HRV-antigens shedding following infection was considerably prolonged in HRV infected group compared to that in L. acidophilus pretreated group and treated group. Furthermore, decreased expression of HRV antigen and little pathological changes in intestinal mucosa were found in L. acidophilus pretreated group and treated group when compared with HRV infected group. Conclusion L. acidophilus may be used as an alternative approach for the prevention and treatment of neonatal mice infected with HRV.
