Objective To explore the general anesthetic EI on the rat fetal neural stem cell proliferation(NSCs) and the role played by JNK in the influence. Methods The cultured rat fetal NSCs were randomly divided into 6 groups (n=8 each):normal group (group N);fat milk group (group F);EI groups(including 8. 12,9. 80,12. 04 mmol/L EI) , 9. 80 mmol/L EI group+20 μmol/L SP600125 group ( group EISP) . After incubated for 12 hours, the cellular effects of EI and cell viability were evaluated by MTT reduction assay. The apoptotic rate of the rat NSCs were determined by flow cytometry, and the expression of protein Caspase-3 was observed by Western blot. Results There was no statistical difference in cell viability, apoptotic rate and protein expression of Caspase-3 in group N and group F. EI group had higher cell apoptotic rate(P<0. 01), protein expression of Caspase-3 (P<0. 05 ) , but lower cell viability than group N ( P<0. 01 ) . And significant differences were found between three do-ses of EI groups (P<0. 05). Compared with EI group, lower cell apoptotic rate (P<0. 01), protein expression of Caspase-3 but higher cell viability were observed in group EISP ( P<0. 05 ) . Conclusion JNK plays an important role in EI-induced cytotoxicity possibly in a dose-dependent manner.

Objective To explore the effect of one-piece shoulder pillow on patients suffering from shoulder pain and skin erubescence during gynecological laparoscopy with lithotomy position and trendelenburg position. Methods Two hundred and six patients who underwent gynecological laparoscopic operation were divided into control and experiment groups according to cardinal or even number of registration. The patients in both groups were set in lithotomy position and trendelenburg position during the operation, with the difference in the use of a common shoulder pillow for support in the control group but no use in the experiment one. On-position time and incidence rate of shoulder pain and skin erubescence were compared between two groups. Result The sholder pain and skin erubescence were less than those of control group (P < 0.05). Conclusion Use of one-piece shoulder pillow can reduce the incidence rates of shoulder pain and skin erubescence after gynecological laparoscopic operation with lithotomy position and trendelenburg position.

BACKGROUND: Continuous blood purification can remove cytokines and inflammatory mediators, maintain homeostasis and prevent the occurrence of multiple organ dysfunction syndrome in patients with severe pancreatitis, which has become the main therapy for severe pancreatitis. Since the hemodialysis technology began to be applied clinical y, the biological and physicochemical properties of hemodialysis membrane materials have been studied. A variety of hemodialysis membranes have been developed in order to improve the biocompatibility and anticoagulant effect in vitro. OBJECTIVE: To investigate the application effect of hemodialysis membranes on severe pancreatitis. METHODS: Ten Wistar rats were selected to make rat models of severe pancreatitis and then were randomized into two groups (n=5 per group): homophone membrane group and polysulfone membrane group. Hemodialysis- related biochemical parameters were detected in the two groups. RESULTS AND CONCLUSION: Compared with the homophone membrane, ultrafiltration coefficient, creatinine clearance, blood urea nitrogen clearance, phosphorus clearance, number of circulating endothelial cel s, and levels of plasma nitric oxide and asymmetric dimethylarginine were significantly lower in the polysulfone membrane group (P < 0.05). Vitamin B12 clearance and amount of pre-congestion increased significantly in the polysulfone membrane group as compared with the homophone membrane (P < 0.05). These findings indicate that the polysulfone membrane for hemodialysis has good biocompatibility, and keeps a stable environment in vivo for severe pancreatitis patients.

OBJECTIVE: To investigate the effect of T lymphoma invasion and metastasis 1 (Tiam 1) overexpression in head and neck squamous cell carcinoma (HNSCC) cells. METHOD: Endogenous expression of Tiam 1 in 8 head and neck squamous cell carcinoma cell (HNSCC) lines was investigated by real-time RT-PCR. A lentivirus vector containing Tiaml was transfected into UM-SCC-47 cells, a head and neck squamous cell carcinoma cell line with little endogenous Tiaml expression. Stable clone, obtained by G418 screening, were assayed by RT-PCR and Western blot to validate the gene expression efficiency. The biological behaviors of the transduced cells were determined by cell counting, MTT and in-vitro migration assay. RESULT: Tiam 1 gene was highly expressed in M2 cell line and it's low level expression was found in UM-SCC-47. Cell counting and MTT assay showed that over-expression of Tiaml significantly promoted cell proliferation (P < 0.05). The cell monolayers overexpressed Tiaml that resulted in a significant increasment of cell migration in infected head and neck squamous cell carcinoma cell lines (P < 0.05). CONCLUSION Tiam 1 gene plays an important role in the growth and migration in head and neck squamous cell carcinoma cell lines. It may be a useful marker for metastasis of head and neck squamous cell carcinoma.

The abnormal results of TCD showed the blood flow velocity in single or multiple branch of artery increased mainly, some of which decreased or became asymmetrial. Conclusion The cervical vertigo in children may result from various kinds of disorders of the atlas, axis or/and C2, C3 vertebrae.

Objective: To explore the anatomy and clinical application of stepladder V-Y advanced flaps based on the lateral calcaneal artery perforator. Methods: Twenty-four lower extremities from 12 adult cadavers were dissected to investigate the perforators emerging along the lateral edge of the achilles tendon, in terms of amount and distribution, relative to the tip of the lateral malleolus. Based on the anatomical findings, stepladder V-Y advanced flaps, based on the perforator(s) of the lateral calcaneal artery (LCA) or the peroneal artery (PA), were used for reconstruction of lower-posterior heel defects in 22 cases. Results: Twenty-four lower extremities from 12 adult cadavers were successfully dissected. The peroneal artery continued to be the lateral calcaneal artery at the level of (6.0±1.4) cm above the tip of the lateral malleolus. Both of them have the perforators distributed to the skin in the achilles tendon area. In the space from the tip of the lateral malleolus to 8.0 cm and above, a total of 71 perforators with diameter larger than 0.5 mm were found in all extremities. Among them, 9%(7/71) were originated from peroneal artery, and 91%(64/71) were the lateral calcaneal artery. In the 22 cases of clinical application, the pedicle of flaps were used, based on the perforator of lateral calcaneal artery and (or) peroneal artery. The size of flaps ranged from 3.5 cm×9.0 cm to 5.0 cm×10.0 cm.There were 3 cases of skin necrosis at the tip of the flap, which were healed after dressing change. The other flaps had completely survived, and the wound healed in the first stage. Follow-up last for 8-24 months after operation. All patients had well recovery of ankle flexion, extension and appearance. They were able to weight-bearing walk, with natural gait. The texture and sensation of the flaps were similar to that of the surrounding skin. There were few obvious scar or contracture deformity. The functional recovery was satisfied. Conclusions The blood supply in the achilles tendon region is mainly from the lateral calcaneal artery, and partly from the peroneal artery. Stepladder V-Y advanced flap based on the lateral calcaneal artery perforator can be used with reliable blood supply and sensation reconstruction, which is a good choice to repair small to medial wounds in heel area.
