The brainstems of 6 rabbits were cut transversely in series and stained fornerve cells or myelin.The architecture of the parabrachial nucleus was studied.Be-sides general observation the length and width of 100 nerve cells in each of the 5nuclear areas chosen were measured and analysed statistically with the help of adigital computer.The following items were calculated:ratio of length to width,itsmean and 95% tolerance interval;area of nerve cells,its mean and 95% toleranceinterval;80% elliptical contour of normal bivariates for the length and width of thecells;cluster analysis of the more dispersed nuclear areas and 80% elliptical contourof each cluster. We concluded that the parabrachial complex consists mainly of 3 nuclei,viz.medial parabrachial nucleus,lateral parabrachial nucleus and magnocellularparabrachial nucleus.Dorsal to the medial parabrachial nucleus there is asmall area,which was tentatively called“d”area in the present study.The medial parabrachial nucleus lies medial to the brachium conjunctivum.Its cells are more or less round in shape,varying markedly in size and canbe clustered into 3 groups according to their size.The lateral parabrachial nucleusis located lateral to the brachium conjunctivum.Its cells are smaller than those ofthe medial nucleus,mostly spindle in shape.Some larger cells can also be seen scat-tered among the smaller ones and the process of clustering has yielded 2 groups ofcells.The magnocellular parabrachial nucleus can be seen in the middle range ofthe nuclear complex.It lies ventrolateral to the brachium conjunctivum with denselypacked large round cells.Its demarkation with the surroundings is sharp.A dorsalextension of this nucleus can be seen wedging between the brachium conjunctivumand the lateral parabrachial nucleus.Its cells are also large and compacted but arespindle in shape.Cells of the“d”area are small and round.Its relation with eitherthe medial or the lateral parabrachial nucleus remain unsettled.The relation between the parabrachial nucleus and the K(?)lliker-Fuse nucleuswas discussed.

With the development of surgical instruments and improved surgical techniques, more and more patients with low rectal cancer can get the effect of the radical cure while preserving the anus. Still, nearly 60%-90% of patients will undergo low anterior resection after surgery Syndrome (down anterior resection syndrome, LARS) LARS can seriously affect patients′ quality of life after surgery. This article will explain the concept, symptoms, possible pathogenesis, prevention, and treatment measures of LARS and provide help for the diagnosis, treatment and prevention of LARS.

The root of Caragana sinica (Buc' hoz)Rehd' is a Chinese folk medicine which is said to be useful for thetreatment of asthenia syndrome,vascular hypertension, leukorrhagia, arthrodynia, and as antiinflammatory agent. In the course of our search for inhibitors of protein kinase C from Chinese herbs,chemical constituentsof the root of C. sinica was examined. Frorn ethanol extract of this crude drug,five isof1avones were isolatedand identified as flemichapparnin B, formononetin, pseudobaptigenin, 5-hydroxy-7, 4'-dimethoxy isoflavone,and 5-hydroxy-7-methoxy-3', 4' -methylenedioxy isoflavone.

Objective To investigate the effect of transplantation of islet allograft with Bcl-2 gene transfection on diabetic rats. Methods Among 26 Wistar rats, 22 were built as model of diabetes, and were divided in to 3 groups. Islet cells expressing Bcl-2 by adenovirus-mediated Bcl-2 gene transfection were transplanted through the portal vein of streptozotocin-induced diabetic rats. The function and rejection of the transplanted islet allograft were evaluated by analysis of blood glucose level and histological examination after transplantation. Results 48h after transplantation, the level of blood glucose was significantly decreased in both transfected and untransfected islets transplantation groups. The euglycemia period of transfected islet cells transplantation group was longer than that of the untransfected islet cells transplantation group (16.4?4.3d vs 6.8?2.2d, P

Objective To explore the effect of hyperglycemia on the survival time, duration of disease remission and complications during induction chemotherapy for acute lymphocytic leukemia(ALL). Methods The treatment-related complications in 98 adult ALL patients with or without hyperglycemia were retrospectively analyzed. Survival time and complete remission duration(CRD) were evaluated using Kaplan-Meier method. Cox regression analysis was used to examine whether hyperglycemia was an independent predictor of disease recurrence and death. Results ALL patients with hyperglycemia were found to be older, and more likely to occur thrombocytopenia. ALL patients with hyperglycemia had a shorter CRD and survival time, and were more likely to develop infection and neuropathy. Conclusion Hyperglycemia during induction chemotherapy for ALL increased the frequency of infection and the risk of disease recurrence and death.

Objective: To observe the effect of Weixikang apozema on growth factor of acetic acid gastric ulcer rats.Methods: The rats were divided into blank control group(abbreviated as blank group),model group,ranitidine group,Weixikang low dosage group(abbreviated as low dosage group) and Weixikang high dosage group(abbreviated as high dosage group) at random,each group has 8 rats.The content of epidermal growth factor(EGF) and transforming growth factor-?(TGF-?) were measured with radioimmunoassay.The protein expression of EGF,TGF? and EGFR were measured with immunohistochemical method.Results: The content of EGF and TGF-? and the protein expression of EGF,TGF-? and EGFR in low dosage group and high dosage group have increased(P

BACKGROUND:A large number of experiments have shown that bone marrow mesenchymal stem cels (BMSCs) have good effects on the treatment of lung disease or improvement of lung injury, and its therapeutic effect is mainly oriented to reduce the inflammatory response. OBJECTIVE: To study the effects of BMSCs combined with reduced glutathione in murine models of bleomycin-induced lung injury. METHODS:BMSCs were isolated from a male NOD/SCID mouse and cel morphology and phenotype were observed. Sixty-four female NOD/SCID mice were randomly divided into a control group, a model group, a BMSCs group and a BMSCs+reduced glutathione group (combined group). The control group received intratracheal injection of normal saline, the model group received intratracheal injection of bleomycin, and the BMSC group received BMSCs injectionvia the tail vein at 2 hours after intratracheal injection of bleomycin, and combined group received BMSCs+reduced glutathione injection via the tail vein at 2 hours after intratracheal injection of bleomycin. Al mice were kiled after 7 days, and levels of tumor necrosis factor-α, interleukin-β, malondialdehyde in lung tissue were detected and lung tissue specimens were obtained for pathological examination. RESULTS AND CONCLUSION:BMSCs were fibroblast-like cels, Positive for CD10, CD13 and CD44, but negative for CD34 and CD45. Compared with the control group, the levels of tumor necrosis factor-α, interleukin-β and malondialdehyde were increased in the model group, while decreased significantly in the BMSCs group and combined group (P < 0.05), especialy in the combined group (P < 0.05). Pathological examination showed that more serious lung injury was observed in the model group and BMSCs group than the combined group. These findings indicate that BMSCs combined with reduced glutathione can more effectively protect against bleomycin-induced lung injury.

Objective To determine whether cultured neural stem cell expresses morphogen molecule sonic hedgehog′s functional receptor patched. Methods Cultured neural stem cell clones were subjected to RT\|PCR after passaged several times in vitro ,the amplification production was sequenced and labeled by digoxingemin and in situ hybridization technique was carried out to detect the cryosection of the neural stem cell clones. Results Most cells in the stem cell clones were positive for sonic hedgehog functional receptor patched,no significant difference was found among the positive cells and the center and peripheral of the stem cell clones.Conclusion\ The sonic hedgehog signal transduction may have important role in the proliferation and differentiation process of neural stem cell.\;[
