Background The extraocular muscles (EOMs) Pulley is considered as the functional origins of the recti EOMs,it is determinants of ocular motility.Objective The structure of the connective tissue around EOMs in cat was studied,and the role of EOMs Pulley to ocular movement was investigated.Methods Five adult cats were involved.The gross anatomy of an orbit in each cat was observed.The other orbit was processed with paraffin imbedding and coronal serial sections.A murine monocolonal antibody to α-smooth muscle actin (α-SMA) was used to show smooth muscle,while Masson trichrome stain was used to show muscle and collagen,and Weigert stain to show elastin.Results An encircling ring of collagen circled EOM was thin and connected to the orbital layer of muscle fiber loosely.Less elastin fibers and little smooth muscle cells were embedded in the collagen ring and connective band.Collagen ring around medial rectus and the connective band between medial rectus and inferior rectus was not more significantly developed than other bands.Conclusions The connective tissue around EOMs in cat may be related to its function of ocular movement,which is not developed.

Objective To discuss the valuable influence of the total-body massage on the facilitation of the rehabilitation for the women in puerperium.Methods Both Chinese traditional medical total-body massage and the biological information theories and its methodology were employed in dealing with 50 cases of puerperants without contraindications,who had labored naturally 12 hours before and who had received cesarean sections 48 hours before. The results were compared with the control group in which conventional preventive health care for puerperants was adopted.Results Notable differences exist in the aspect of lochia,defecation,lactation and emotions between the two groups.Conclusion Significant benefits can be obtained from the massage to facilitate the rehabilitation of the women in puerperium while promoting their quality of lives and broadening the coverage of services of the preventive health care for the puerperants.

Chinese patent medicine with double identity was a special phenomenon, and many preparations not only were prescription drugs but also over the counter ( OTC) drugs, which brought a lot of trouble. Based on statistics of list of OTC medicines of CFDA, related varieties, route of administration and functions of these drugs were searched. The causes of insufficient were analyzed and the potential risk was investigated. To ensure the safety of drug usage for the patient, risk management system should be set up by improving the technical requirements for registration, improving the drug labels and manuals, playing the role of pharmacists in pharmacy services and raising awareness of doctor and patient for these drugs.

OBJECTIVETo explore the prognostic factors for rectal cancer patients with synchronous liver metastases.

METHODSData from a total of 77 cases of rectal cancer with synchronous liver metastases treated in our center from January 2002 to December 2008 were collected and reviewed. The total survival rate was analyzed by Kaplan-Meier method. Log-rank test and Cox regression model with SPSS 17.0 software were used to analyze 13 factors including clinicopathological factors and treatment choices.

RESULTSThe median survival time of the 77 cases was 12 months. The 1-, 2-, 3- and 5-year survival rates were 47.7%, 28.0%, 13.1%, and 1.5%, respectively. Univariate analysis with Kaplan-Meier method revealed that the differentiation of the primary tumor, T-stage, N status, the distribution, number and size of liver metastases, extrahepatic disease, serum CEA level at diagnosis and treatment modality were prognostic factors (P < 0.05). Multivariate analysis showed that the differentiation of the primary tumor (P = 0.007), T-stage (P = 0.027), the size of liver metastases (P = 0.003), serum CEA value at diagnosis (P = 0.000) were independent prognostic factors for rectal cancer patients with synchronous liver metastases.

CONCLUSIONThe factors affecting the prognosis for rectal cancer patients with synchronous liver metastases are the differentiation of the primary tumor, T-stage, N status, the distribution, number and size of liver metastases, extrahepatic disease, serum CEA level at diagnosis and treatment modality. The differentiation of the primary tumor, T-stage, the size of liver metastases, and serum CEA value at diagnosis are independent prognostic factors.

Objective To isolate and identify the adult neural stem cells from the parenchyma of spinal cord in adult mouse.Methods The parenchymal spinal cord from adult mouse was dissected and dissociated by mechanical trituration.The tissue suspension was cultured in serum-free DMEM/F12 medium supplemented with EGF and B27.The cell colonies generated from a single cell were screened by limited dilution and incubated with BrdU.The cell colonies were transferred into medium with serum to induce differentiation.The cells were identified with antibodies to Nestin,BrdU,MAP2 and GFAP by immunofluorescence staining.Results The cells were cultured for seven days to generate proliferative neurospheres.The majority of cells in these neurospheres expressed Nestin and were differentiated into MAP2-positive cells and GFAP-positive cells in medium containing with fetal bovine serum.Conclusion A significant number of neural stem cells are present in the parenchymal adult mouse spinal cord and can proliferate and also give rise to neurons and glia in vitro.

Objective To introduce a new technique for urethral coverage in Snodgrass hypospadias repair,and to evaluate its effectiveness and complications.Methods From April 2003 to February 2006, this new procedure was performed in 289 children with hypospadias aged 3 months to 12 years (mean age,2. 4 years).The native meatus of urethra was identified subcoronal in 78 cases,penile/shaft in 136,penoscrotal in 36 and scrotal in 16;and 23 cases had undergoneⅡstage operation and re-operation.The overlapping coverage with bilateral shaft based vascularized dartos pedicle was done in the new urethra by Snodgrass hy- pospadias repair in these children.Results All the cases were followed for 3 months to 2 years.Postoper- atively,urinary fistulas developed in 32 cases (11%).Of them,11 were cured spontaneously within 4 weeks. The incidence of actual urinary fistula was 7% (21/289).Of the 21 fistulas which were not cured,11 (5%) occurred in 214 cases of distal hypospadias;and 10 (13%) in 75 cases of proximal hypospadias,Ⅱstage and re-operation.No dehiscence and diverticulum was found.Combined with mucosal collar technique,the ventral skin of the penis was sewn on the midline.During the follow-up,excellent cosmetic results with normal-ap- pearing circumcised penis were achieved in most patients.Conclusions Bilateral shaft based vascularized dartos pedicle urethral coverage procedure is a reliable and effective method for preventing urethral cutaneous fistulas and dehiscence.This method can reconstruct a satisfactory cosmetic appearance of the penis.

BACKGROUND: The effect of pituitary adenylate cyclase activating polypeptide (PACAP) during traumatic brain injury (TBI) and whether it can modulate secondary injury has not been reported previously. The present study evaluated the potential protective effects of ventricular infusion of PACAP in a rat model of TBI. METHODS: Male Sprague Dawley rats were randomly divided into 3 treatment groups (n=6, each): sham-operated, vehicle (normal saline)+TBI, and PACAP+TBI. Normal saline or PACAP (1g/5L) was administered intracerebroventricularly 20 minutes before TBI. Right parietal cortical contusion was produced via a weight-dropping method. Brains were extracted 24 hours after trauma. Histological changes in brains were examined by HE staining. The numbers of CD4+ and CD8+ T cells in blood and the spleen were detected via flow cytometry. RESULTS: In injured brain regions, edema, hemorrhage, inflammatory cell infiltration, and swollen and degenerated neurons were observed under a light microscope, and the neurons were disorderly arrayed in the hippocampi. Compared to the sham group, average CD4+ CD8– lymphocyte counts in blood and the spleen were significantly decreased in rats that received TBI+vehicle, and CD4– CD8+ were increased. In rats administered PACAP prior to TBI, damage was attenuated as evidenced by significantly increased CD4+, and decreased CD8+, T lymphocytes in blood and the spleen. CONCLUSION: Pretreatment with PACAP may protect against TBI by influencing periphery T cellular immune function.
