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.

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.

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

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.

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 investigate the relationship between clinical types and related risk factors in female patients with post-adolescent acne.Methods Female outpatients with post-adolescent acne aged more than 25 years were enrolled from Department of Dermatology of Renji Hospital between January and October 2016.A questionnaire survey was conducted to investigate related risk factors for post-adolescent acne in the females.Skin lesions and clinical types were evaluated by dermatologists.Statistical analysis was carried out by t test for comparison of means between two groups and by chi-square test for comparison of ratios.Results A total of 312 female patients with post-adolescent acne completed the survey,including 268 (85.9％) with mild to moderate acne and 44 (14.1％) with severe acne,241 (77.2％) with persistent acne and 71 (22.8％) with late-onset acne,or 102 (32.7％) with comedonal post-adolescent acne (CPAA) and 210 (67.3％) with papular post-adolescent acne (PPAA).Survey on related risk factors showed that 121 patients reported seasonal factors and 59 (18.9％) patients became worse in summer,and spicy,sweet and fried foods can aggravate the condition in 131 (42％),93 (29.8％) and 85 (27.2％) patients respectively.Other risk factors such as premenstrual period (62.8％,196/312),psychological factors (51.6％,161/312) and exogenous chemical exposures (43.6％,136/312) were complained of by the patients.Furthermore,premenstrual period,diet and constipation were found to be more associated with PPAA compared with CPAA (x2 =4.523,4.068,3.910,respectively,all P ＜ 0.05).Exogenous chemical exposures,such as the use of cosmetics,exposure to polluted air environment and occupational hazards,were more associated with CPAA compared with PPAA,as well as with late-onset acne compared with persistent acne (x2 =6.579,9.057,both P ＜ 0.05).In addition,premenstrual exacerbation occurred more frequently in patients with persistent acne compared with those with late-onset ache (x2 =4.512,P ＜ 0.05).Conclusions The risk factors for the occurrence of female post-adolescent acne are very complex.Premenstrual exacerbation plays a major role in the aggravation of papular and persistent post-adolescent acne,diet and constipation are more associated with PPAA,and exogenous chemical exposures are still be considered in the aggravation of comedonal and late-onset post-adolescent acne.Thus,clinical types should be considered in the diagnosis and treatment of post-adolescent acne in females.

AIM: To find out whether traditional Chinese medicine Angelicae Sinensis has direct suppressive effect on schistosome egg-induced granulomatous response. METHODS: The lung model of granuloma response was established by injecting living eggs of Schistosoma japonicum into the tail veins of eggs-sensitized mice then the preparation of Angelicae Sinensis were given intraperitoneally once a day for ten days. In vitro model of granulomatous reaction was set up by incubating dry schistosome eggs together with those splenocytes isolated from schistosome infected-mice or from the mice with pulmonary granuloma formation. Different doses of the preparation was, in the need of experiment, added to culture fluid. The sizes of granulomas formed surrounding single egg in lungs or the intensity of in vitro granulomatous responses were measured and observed. RESULTS: The average diameter of pulmonary granulomas in administered group was significantly smaller than that of the control ( P
