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.

Lesion was made individually to the various cortical areas in 14 rats.The cortico- fugal fibers terminating into cochlear nuclei were traced in sections by means of the modified Nauta and Fink-Heimer silver staining method.The results were as follows: 1.After damaging the auditory area or somato-sensory area 1(SI)of the cerebral cortex unilaterally,degenerating fibers were found bilaterally in the ventral and dorsal cochlear nuclei.This result showed that the above cortical areas have direct descending connection with the cochlear nuclei. 2.No degenerating fibers were found in the cochlear nuclei after the ablation of the motor or visual area of the cerebral cortex,which demonstrated that the cochlear nuclei do not receive descending fibers from the above cortical areas. 3.The pathway from the cerebral cortex to the cochlear nuclei was:The descending fibers which originated from the auditory area or SI area ipsilaterally passed through the capsula interna and basis pedunculi,and part of these fibers passed dorsally and downward to the lateral portion of the reticular formation of the midbrain;and from there the fibers passed through the lemniscus lateralis and dorsal acustic stria to the cochlear nuclei of the ipsilateral side.The cochlear nuclei in contralateral side also received the corticofugal fibers by way of the dorsal acustic stria.These fibers might cross to the contralateral side at the region in the posterior commissure,superior colliculus commissure and inferior colliculus commissure.

To compare the effects of laparoscopic total or subtotal hysterectomy and myomectomy on ovarian reserve by measuring the serum level of anti-Mullerian hormone (AMH).A total of 96 patients with uterine fibroids underwent total laparoscopic hysterectomy (TLH group,n =32),laparoscopic subtotal hysterectomy (LSH group,n =31) and laparoscopic myomectomy (LM group,n =33).Changes in ovarian reserve were examined by measuring the level of AMH pre-operation and at 1 and 4 months post-operation.No significant differences existed in AMH in LM group[(1.42 ±0.65),(1.31 ±0.53) & (1.33 ±0.61) μg/L,P ＞ 0.05].The levels of AMH in both groups were significantly lower than those at pre-operation [(1.17 ± 0.11),(1.01 ±0.10),(0.48±0.54) & (1.18±0.93),(0.45 ±0.39),(0.14±0.0) μg/L,P＜0.001].The mean percentage decrease in AMH was lower in TLH group than that in LSH group at 4-month follow-up [(-37.4 ± 37.6) ％ vs.(-27.0 ± 23.0) ％,P =0.017].The results showed that LM had no effect on ovarian reserve.Both LSH and TLH had adverse effects on ovarian reserve and TLH was more marked.
