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.

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.

Background Carbachol solution (0.01％) is an agonist of M cholinoceptor and skeletal muscle N cholinoceptor,and it is used to play miotic effect and open peripheral iridectomic hole during the surgery of implantable collamer lens (ICL) implantation in order to lower intraocular pressure (IOP).However,the anterior chamber injection of 0.01％ carbachol solution often causes relevant complications,while whether lower dose of carbachol solution is effective and safe is unclear.Objective This study was to compare the effectiveness and safety between 0.01％ carbachol solution and 0.005％ carbachol solution after anterior chamber injection during the ICL implantation.Methods One hundred and fifty-two eyes of 76 cataract patients were included in Daping Hospital of Third Military Medical University from September 2014 to September 2015.ICL implantation and periphery iridectomy were carried out on both eyes of the patients and the 0.01％ carbachol solution was injected into the anterior chamber during the surgery of the right eyes and 0.01％ carbachol solution was used in the left eyes.The operation duration and IOP at postoperative 2 hours and systemic choline-like reaction were compared between 0.01％ carbachol solution group and 0.005％ carbachol solution group.Results The mean operation duration was (11.86± 2.39) minutes and (11.22 ± 1.85) minutes in the 0.01％ carbachol group and 0.005％ carbachol group,without significant difference between two groups (t =1.851,P =0.066).IOP was (15.76 ± 2.18) mmHg and (13.58 ±2.24)mmHg in the 0.01％ carbachol group before and after surgery,and those in the 0.005％ carbachol group was (15.70±2.35)mmHg and (13.12±2.17)mmHg,there was no significant difference in the IOP between the two concentrations of carbachol (Fsroup =0.986,P=O.322).The IOP at postoperative 2 hours was lower than that before operation,the difference was statistically significant(Ftime =97.339,P =0.000).There was no interaction between drug concentration and time (Fcorrelation =0.772,P =0.381).The incidences of complications,such as dizziness,nausea and vomiting,were lower in the 0.005％ carbachol group than those in the 0.01％ carbachol group (x2 =13.01,5.16,4.03,all at P＜0.05).Conclusions Carbachol solution (0.005％) can play intraoperative miosis effect and maintain effective operation duration in ICL implantation.In addition,the application of 0.005％ carbachol solution is quite safe in both intraoperation and postoperation.

ObjectiveTo recognize the features of genitourinary dysfunction in multiple system atrophy (MSA) and the importance of videourodynamics.Methods5 cases of MSA were reviewed.ResultsGenitourinary dysfunction in MSA included voiding problem, nocturnal urinary frequency, urgency, impotence and so on. The characteristic appearance of videourodynamics was that postvoiding volume more than 100 ml, detrusor-external sphincter dyssynergia (DESD) and open bladder neck at the start of bladder filling. The abnormal sphincter electromyography comprised of abnormal spontaneous activity, motor unit potentials (MUPs) more than 13 ms, polyphasic potentials more than 60%. MRI showed brain atrophy and the "hot cross bun" signal in the pontocerebellar degeneration.ConclusionMSA is a disorder characterized by progressive neuronal atrophy at certain sites of the central nervous system that control the urogenital function. MSA-related urological symptoms are analogous with symptoms of bladder outlet obstruction. It is necessary to take some reasonable investigations for avoiding misdiagnosis and unnecessary surgery.
