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.

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 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.

Objective To investigate whether antiseptic central venous catheters (CVC) modified with chlorhexidine acetate and silver sulfadiazine can be beneficial in reducing bacterial colonization and catheter-related infection. Methods Prospective controlled non-blinded randomized clinical trial was conducted. Seventy adult inpatients with CVC from intensive care unit of General Hospital of Chinese People's Armed Police Force during June 2007-June 2009 were enrolled. Their baseline characteristics, APACHE Ⅱ score and therapeutic interventions were comparable. Patients were randomly received either an antiseptic CVC ( antiseptic group, n = 28) or a standard two-lumen CVC ( control group, n = 42 ). Microbiological evaluation was done after CVC removal. A catheter bacterial colonization ( CBC) was considered if bacterial growth of > 15 CFU was found by semi-quantitative roll-plate technique from a proximal or distal catheter segment. A catheter-related infection ( CRI) was defined as a colonized catheter with local signs of inflammation. A catheter-related bloodstream infection ( CR-BSI) was defined as a colonized catheter with isolation of the same organism from the patient' s blood with accompanying clinical signs of infection. SPSS 11.5 software was used for statistical analysis. Kaplan Meier curve was used to evaluate the association between CVC retention time and bacterial colonization or infection, and Log-rank test was performed to compare between the groups. Results CVC was removed from 3.6% (1/28) patients of antiseptic group and 21.4% (9/42) patients of control group because of infection (x2 = 5. 143, P <0. 05). Colonization of CVC was observed in 7. 1% (2/28) patients from antiseptic group and 35. 7% ( 15/42) from control group (x2 =7.458, P<0.01). CBC or CRI was not observed in antiseptic group until day 19, while CRI occurred at day 6 in the control group. CVC colonization and infection were developed in 31.4% and 14. 3% patients of antiseptic group during day 14-day 28 respectively, while the rates in the control group were 90% and 70% ( u = 27.5 and 14.31, P < 0.01). Conclusions Antiseptic CVC modified with chlorhexidine acetate and silver sulfadiazine can significantly lower the risks of CBC and CRI. But more than 50% patients would develop infection when colonization occured, no matter patients receive standard or antiseptic CVC. After CVCs have been inserted for > 2 weeks, the colonization and infection will increase significantly in both standard or antiseptic CVC, so to shorten the insertion time is an effective measure to decrease the CVC-related infection.

Objective:To compare 3 maxillofacial trauma scoring systems in mandible fracture grading.Methods:Maxillofacial Injury Severity Score(MISS),Maxillofacial Injury Severity Score(MFISS),Mandible Injury Severity Score(S5)were used in the analysis of mandible fracture severity in 313 cases with mandible fractures.The results were statistically analyzed.Results:S5 score showed higher correlation with operation time,operation charge and hospitalization expenses than MFISS and MISS,and it could distinguish single and multiple mandible fractures effectively.It was also a significant factor affecting the cost of hospitalization.Conclusion:The Mandible Injury Severity Score was more suitable for the scoring of mandible fracture.
