126 adult male Wistar rats were used.A 4?6 cm~2 standard island skin flap wasraised on one side of the abdominal wall of the rats.In the flaps of the experim-ental group,only the superficial epigastric and lateral thoracic vein were preserved.The process of revascularization,histological changes,glycogen content and lactatedehydrogenase (LDH) activity of the flap were observed postoperatively with Indian ink injection,X-ray,microscopy and microspectrometry.The shrinking rateand degree of edema of the experimental flap were also observed and all comparedwith those of the control flaps.The results indicated that the flaps of experimentalgroup had a higher survival rate and lower degree of edema,and its glycogencontent and LDH activity decreased markedly on the lst postoperative day,andincreased gradully afterwards.Revascularization started on the 2nd postoperative day,such as capillary anastomoses passing through the cut edges of the flap,vesselsentering the flap from the recipient bed,vessels becoming tortous,dilated,andmarkedly proliferated.The results suggest that there was a true plasmatic circulationat the early stage in the simple venous flap and turns to a normal vascular type byrevascularization.The vividness of a flap may be indicated by the variance of themetabolism of carbohydrate in the skin flap.

Central nervous system (CNS) damage caused by enterovirus 71 (EV71) infection is the main reason for its mortality and morbidity.In recent years,survival rate of EV71 infection-associated CNS damage in children is improved.However,the condition of survivors with sequelae is still unclear.It is important to understand its prognosis in order to improve the life quality of children with CNS damage after EV71 infection.In this paper,the prognosis and sequelae classifications of EV71 infection-associated CNS damage are described.

Objective To evaluate the effect of permissive hypercapnia on pulmonary function and in-flammatory responses of the collapsed lung of patients underwent video-assisted pulmonary lobectomy after one-lung ventilation.Methods Fifty patients,aged 38-65 years,ASA Ⅱ or Ⅲ,including 30 males and 20 females,scheduled for video-assisted pulmonary lobectomy were selected and divided into two groups ran-domly,with 25 patients in each group.During the surgery,PaCO2 of patients in group C were maintained during 35 to 45 mm Hg,while in group H the value were 55 to 65 mm Hg.The arterial blood samples were collected at 1 min before one-lung ventilate (T1 ),30 min after one-lung ventilate (T2 )and 30 min after re-flow of the collapsed lung (T3 )for arterial blood gas analysis,then the respiratory index of each patient was evaluated.Peripheral venous blood and bronchoalveolar lavage fluid draw from left lower lobar of the col-lapsed lung were collected to evaluate the levels of TNF-α,IL-6,and IL-10 at T1 ,T2 and T3 .The peak in-spiratory pressure,plateau pressure and tidal volume were also recorded to calculate lung dynamic compli-ance.Results Compared to group C,peak inspiratory pressure of group H was significantly higher;the IL-10 level of bronchoalveolar lavage fluid of the collapsed lung and the pulmonary dynamic compliance of group H were significantly higher at T2 and T3 ,and the concentrations of TNF-α,IL-6 of bronchoalveolar lavage fluid,the peak pressure,and respiratory index of group H were lower significantly at the same point of time (P <0.05).Conclusion Permissive hypercapnia would inhibit inflammation response of collapsed lung after one-lung ventilation effectively,improve lung diffusion capacity and pulmonary compliance.

Objective To compare the influence of three kinds of complete media with 0. 10 ,0. 15 ,0. 20 fetal bo-vine serum( FBS) on purity and cycle of rat bone marrow mesenchymal stem cells ( BMSCs) cultured in vitro and to seek suitable FBS concentration for the cultivation of the stem cells. Methods SD rats were executed by cervical dislocation method and used whole bone marrow adherence to isolate rat BMSCs. Experiment was divided into A, B,C,3 groups. Compared the expression of CD45, CD29, CD90, CD44 in the three groups in 2,3,4,5 passages ( P2 , P3 , P4 , P5 );the cells of P3 in group A were digested and cultured in three different concentration of com-plete culture media for four days, measuring cell cycle in 24,48,72,96 h by flow cytometry instrument. BMSCs of P3 were collected and inoculated to 6 pieces of 96-well plates, then vaccinated with complete media with 0. 10, 0. 15,0. 20 FBS in every plate, one culture plate was taken out for optical density(OD) meaturement every day with CCK-8. Results CD45 was negative, CD29, CD90, CD44 were positive. The difference of BMSCs surface markers cultured in the three kinds of complete media was bigger in the first two passages, but the difference was less in P3 , P4 , all could obtain pure BMSCs in P4 relatively;according to the results of the cell cycle at the same time, G0/G1 phase:with the increase of concentration of fetal bovine, G0/G1 phase reduced and had no diference in A, B, C groups;G2/M phase:there was difference between them after 24 h(P<0. 05,F=12. 412), but with the extension of time, the differences disappeared;S phase:there was no difference in the three groups;S+G2/M phase increased with the concentration of FBS. According to the result of cell vitality, the OD of ABC three groups increased in turn in 24 h, and there was difference(P<0. 05,F=5. 002), but with the extension of time, there was no obvious difference between them. Conclusion The three kinds of culture media in P4 can obtain pure BM-SCs, cell cycle and vitality show three complete media can promote the growth of BMSCs. There is no difference between them. Culture media with 0. 10 FBS can satisfy the isolation and amplification of BMSCs, in order to ob-tain pure BMSCs in the short term, using culture media with 0. 15 and 0. 10 FBS in the primary culture and subcul-ture respectively.

Anaplastic thyroid cancer (ATC) is the most aggressive thyroid tumor, with lower morbidity and higher mortality rates. Radical surgery could improve local control and survival rates. Conformal radiotherapy is superior to conventional radiotherapy, which could improve the patients’ quality of life. There are a few chemotherapeutic drugs against ATC, and the outcome of chemotherapy alone is modest. Concurrent chemoradiotherapy can prolong the survival. Targeted therapy brings new hope for refractory patients. Many cancer centers are exploring surgery, radiotherapy, chemotherapy, targeted therapy and other biological treatment of comprehensive application, in order to enhance the curative effect. This article reviewed the foregoing treatments for ATC.

Enterovirus 71 (EV71) is one of the most important causes of hand-foot-mouth disease and herpangina.EV71,due to its neurotropic nature,can also cause severe complications of the central nervous system than other types of enterovirus.EV71 infection also causes devastating syndromes such as acute pulmonary edema,pulmonary hemorrhage and cardiopulmonary failure.In this review,clinical manifestations and the pathogenesis of central nervous system dysfunction after EV71 infection were described.
