Lesion was made individually to the verious cortical areas in 14 adult cats.Thecorticofugal fibers terminating into vestibular nuclei were traced in sections by meansof modified Nauta silver staining method.The majority of cortical efferents which terminated to the vestibular nuclei deri-ved from somato-sensory area Ⅰ.A few fibers originated from the cortical motorareas,and some fibers derived from vestibular area and somatosensory area Ⅱ.Thefibers originated from the visual and auditory areas were not observed.The corticovestibular fibers descended within the pyramidal tract.These fibersleft pyramidal tract at the level of pons.Then,most of them reached to the vesti-bular nuclei ipsilaterally,and others reached bilaterally.Terminal degeneration was present throughout the whole extent of the vestibularnuclei.The total number of preterminal degenerating fibers in the nuclei was small.The anatomical and functional significance of our findings are discussed.

Objective To comprehensively know clinical pathological change of recurrent anterior dislocation of shoulder joint by arthroscopy. Methods 52 patients with recurrent anterior shoulder dislocation were inspected by arthroscopy in our institute, 38 cases were male, 14 cases were female; the mean age were 24.7, from 16 to 49 years old. 2 epilepsy patients were excluded, the other 50 cases were divided into two groups, the first group included 32 shoulder dislocated patients accompanied with shoulder hyper-laxity. The other group included 18 purely traumatic shoulder dislocated patients. All patients were explored by arthroscopy and all pathological changes were recorded and the difference of pathological change between the two groups were contrasted. Results 51 cases showed anterior-inferior labrum injury, 50 cases showed Hill-Sachs injury, 32 cases showed biceps-tendon inflammation or injury, 30 cases showed bone or cartilage injury of anterior-inferior glenoid, 29 cases showed SLAP injury, 7 cases showed rotator cuff injury. Anterior-inferior labrum injury: labrum abraded disappear was more occurred in pure traumatic group(P=0.055) and ALPSA injury was more in hyper-laxity group (59.4% to 38.9%, P=0.164). Bone or cartilage injury of anterior-inferior glenoid were more occurred in purely traumatic group(P=0.083, P=0.052). Hill-Sachs injury was more superficial or only cartilage injury in hyper-laxity group but wider and deeper in purely traumatic group. Conclusion The general pathological changes of recurrent anterior shoulder dislocation sucessively are: anterior-inferior labrum injury, Hill-Sachs injury, biceps-tendon inflammation or injury, bone or cartilage injury of anterior-inferior glenoid, SLAP injury and rotator cuff injury. The pathological changes of the hyper-laxity group were lighter than purely traumatic group.

Objectives: To research the effects of recombinant human growth hormone(rhGH) with total parenteral nutrition(TPN) on the old patients following abdominal surgery. Methods: 26 old patients receiving TPN after major abdominal surgery were selected and distributed to study group(rhGH+TPN, n =13) and control group(TPN only, n =13).For 7 days after operation, rhGH (8 U/d) or normal saline(in control group) were used. The patients' weight, serum albumin, right hand grip, sleep time and the time of incision cicatrized were determined. Results: The increase of weight, level of plasma albumin, grip power of right hand and sleep time were improved more in study group than those in control group. The incision cicatrized time was also shortened in study group. Conclusions: Growth hormone can promote protein synthesis, accelerate incision healing and reduce the postoperative fatigue syndrome.

Objective:To explore the discrimination against the patients with mental disorders and current situation of awareness of mental health knowledge of medical postgraduates and their relationship.Methods:A questionnaire survey was conducted among 132 medical postgraduates in October 2016 using the assessment scale of discrimination against patients with mental disorders and mental health knowledge awareness questionnaire,which derived from mental health work indicators survey and evaluation program issued by the General Office of the Ministry of Health in 2010.Results:There was significant gender difference (P <0.01)in the overall score and the score of each dimension of assessment scale of discrimination against patients with mental disorders,and the score of mental health knowledge was (13.93-± 3.13).There was significant negative correlation between scores of assessment scale of discrimination against patients with mental disorders and mental health knowledge.Multiple linear regression analysis showed that awareness of mental health knowledge could predict the discrimination against the patients with mental disorders and all its factors.Conclusion:Awareness of mental health knowledge in medical post graduates can predict the discrimination against the patients with mental disorders.Medical universities should carry out corresponding education and publicity work with pertinence.

Objective: To explore the effects of ranitidine on pharmacokinetics of rhein in rats after oral administration of Dachengqi Decoction (DCQD), a compound traditional Chinese herbal medicine. Methods: Twelve male Sprague-Dawley rats were divided into DCQD group and DCQD plus ranitidine group, and were orally administered with DCQD at a dose of 10 g/kg or DCQD (10 g/kg) combined with ranitidine (150 mg/kg), respectively. Blood samples were gathered after a series of time intervals. Metabolism of rhein was determined with a reversed-phase high-performance liquid chromatography with internal standard of 1, 8-dihydroxyanthraquinone and the data were analyzed with DAS 2.1 program. The pharmacokinetic parameters were compared between the two groups. Results: The pharmacokinetic parameters of rhein in the DCQD group, including peak concentration (C(max)), area under the plasma concentration-time curve (AUC), distribution phase half-life (t(1/2alpha)), elimination rate constant (K(10)) and central to peripheral transfer rate constant (K(12)), were significantly different to those in the DCQD plus ranitidine group (P<0.05, P<0.01). There were no significant differences in the other parameters between the two groups. Conclusion: Ranitidine can influence the pharmacokinetics of rhein in rats after oral administration of DCQD.

Objective To investigate the inhibitory effect of melatonin on the proliferation activity of murine foregastic carcinomac ( MFC) cells via melatonin membrane receptors MT 2 and its relationship with the signaling pathways of mitogen-activated protein kinases ( MAPKs), phosphatidylinositol 3-kinase ( PI3K)-Akt.Methods Using siRNA technology to silence MT2 expression, we examined the ability of melatonin to inhibit the proliferation activity of MFC cells and its influence on the phosphorylation of ERK 1/2 and Akt.Results We found two interesting effects of SiRNA-mediated silencing of MT2 expression.Firstly, it significantly antagonized the inhibitory effect of melatonin on the proliferation activity of MFC cells .Secondly , it partially blocked the inhibitory effect of melatonin on the phosphorylation of ERK 1/2 and Akt.Conclusion Our results suggest that melatonin can inhibit the phosphorylation of ERK 1/2 and Akt via MT2 receptors , thereby inhibiting the proliferation of gastric cancer cells .

Objective:To review and compare the clinical features and treatment outcomes of oral and maxillofacial space infection (OMSI)between diabetic and non-diabetic patients.Methods:Clinical data of 43 diabetic patients with OMSI(simultaneoustly treated by blood sugar control)and 84 of non-diabetic patients with OMSI were reviewed,the clinical features and treatment outcomes were compared.Statistical analyses were conducted by T test,the chi square test and variance analysis.Results:Diabetic patients with OM-SI were older(P =0.000),had more spaces involved concurrently(P =0.035 )and had higher blood sugar at presentation(P =0.000).There was no significant difference between groups about the use and change of antibiotics,the incision times,hospital stay durition and the incidence of the complications.Conclusion:The prognosis of the diabetic patients with OMSI under the strict control of the blood glucose concentration has no significant difference from the non-diabetic patients with OMSI.Diabetic patients with OMSI have older age and more spaces involved,and special attention should be paid.
