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.

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.

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.

A novel method based on the separation and enrichment effect of magnetic beads and the fully complementary hybridization of two DNA strands was developed for highly sensitive detection of bacterial DNA using a surface-enhanced Raman spectroscopy (SERS) with 5,5’-dithio-bis(2-nitrobenzoic acid) (DTNB)-modified gold nanoparticles as reporter probes. Capture probe was immobilized onto the surface of streptavidin-enwrapped magnetic beads ( SA-MB ) through high affinity between biotin and avidin, by which the target bacterial DNA sequences that connected with the reported probe decorated AuNPs with DTNB and SH-DNA ( AuNPs@DTNB@DNA) were captured and loaded onto the magnetic beads by the hybridization reaction with the capture probe. Compared with previous methods, this design shortened the distance between particles by the ways that the magnetic beads tempted to nanoparticles aggregation, and produced the plasma resonance coupling effect, which increased the SERS signal significantly. The results showed that, under the optimized conditions and in the concentration range from 5 pmol/L to 5 nmol/L, the method performed a good linear relationship between Raman intensity and DNA concentration. The limit of detection ( LOD) of bacterial DNA was estimated to be 5 pmol/L. The method is simple and low cost, and can be used in the sensitive and selective detection of bacterial DNA.

Currently,surgical treatments in tennis elbow include open,arthroscopic and percutaneous procedures.Open surgery,having definite curative effects,is commonly used.There are different surgical methods based on different hypotheses about the pathogenesis of tennis elbow,such as detachment of common extensor origin,resection of annular ligament,denervation surgery and resection of microvascular nerve bundle.There is a huge difference in open surgery of tennis elbow between China and abroad.Debriding or releasing extensor carpi radialis brevis and common extensor tendon are mostly used abroad though it remains controversial whether we should release or debride with tendon,as well as whether it is better to decorticate on lateral epicondyle or not.In China,tennis elbow is treated with resection of microvascular nerve bundle except for debridement and release of tendon.As for evaluation criteria,the following methods,grip strength,grading system and visual analogue scale have been used in researches.However,cure rate and response rate are valuation criteria for resection of microvascular nerve bundle in China.The evaluation criteria are different among various surgical methods,even in the methods,especially for grading system.Each research has unique standards to define excellent,good,fair and poor outcomes.Complications of tennis elbow open surgery are rare,while subcutaneous hematoma is the common complication.
